Description

LIQUID HEATING CONTAINER
Field
The present application relates to the technical field of small home appliances, and in particular, to a liquid heating container.
Background
A liquid heating container is generally provided with a steam vent at a spout at an upper end of a container body. During heating, steam will emerge out of the steam vent, preventing dangers such as explosions.
However, the above described manner in which the steam vent is provided affects the heat preservation performance of the liquid heating container on one hand, and makes it easy for steam to scald a user on the other hand due to the fact that the steam vent is provided on top of the body at a location which is readily accessible by a user. It is well known that scald caused by steam is more serious than that caused by hot water.
Summary
Therefore, an objective of the present application is to provide a liquid heating container that ensures utilization safety of a user while improving heat preservation effect.
According to a first aspect of the present application, a liquid heating container is provided, the liquid heating container comprising: a container body inside which a closed liquid storing chamber is formed and an upper part of which is provided with a steam outlet in communication with the liquid storing chamber; a bottom lid provided at the bottom of the container body and inside which a cooling mechanism is provided; and a handle provided at a side of the container body and inside which a steam conduit is provided, wherein an upper end of the steam conduit is in communication with the steam outlet, and a lower end of the steam conduit extends into the bottom lid and is in communication with the cooling mechanism.
When the liquid heating container according to an embodiment of the present application works, steam produced from the container body enters the steam conduit via the steam outlet and flows towards and enters the cooling mechanism smoothly and is condensed therein. Compared to the prior art, the flow path of the steam is modified (it does not emerge at easily accessible locations, such as a spout), and steam is further condensed, which reduces the risk of scalding a user and ensures the user’s utilization safety. In an embodiment, the container body comprises a container having an inner chamber that has an upper opening and a lid assembly that blocks the upper opening of the container so as to form the liquid storing chamber; wherein the steam outlet is formed at the lid assembly, or at an upper side wall of the container.
In the liquid heating container according to an embodiment of the present application, the steam outlet can be provided at a corresponding part based on actual needs. In the event that the steam outlet is formed at the lid assembly, it can be ensured that the effective volume for containing liquid in the inner chamber of the container is not affected.
In an embodiment, the cooling mechanism is a condensing conduit formed at an upper surface of the bottom lid, an inlet located at a first end of the condensing conduit being in communication with the lower end of the steam conduit, and wherein the bottom lid is further provided with a discharging through hole that puts the condensing conduit in communication with an exterior of the bottom lid.
In an embodiment, an outlet of the condensing conduit is located at a second end of the condensing conduit opposite to its first end, the condensing conduit having a width and a height that gradually decrease in a direction from the inlet to the outlet. Thus, during its course of flowing in the condensing conduit, steam will gradually be condensed on the surface of the passage wall in contact and thus quickly form condensed water to be discharged smoothly.
In an embodiment, the cooling mechanism comprises a condensing skeleton in the shape of an oblong bar extending from the lower end of the steam conduit along the upper surface of the bottom lid, a first end of the condensing skeleton being connected to the lower end of the steam conduit, a lower surface of the condensing skeleton and the bottom lid together enclosing and forming the condensing conduit, the discharging through hole being located below a second end of the condensing skeleton.
Further, the lower surface of the condensing skeleton protrudes upward to form an upper passage groove that opens downward, a lower edge of the upper passage groove abutting against the upper surface of the bottom lid.
Specifically, the condensing skeleton comprises a condensing skeleton top wall in the shape of an oblong bar, and a first side wall and a second side wall connected to two sides of the top wall, respectively, a lower edge of the first side wall and a lower edge of the second side wall both abutting against the upper surface of the bottom lid so that the condensing conduit is formed between the top wall, the first side wall, and the second side wall of the condensing skeleton and the upper surface of the bottom lid. In an embodiment, the condensing skeleton further comprises a third side wall that blocks an opening of the second end of the condensing skeleton. By providing the third side wall, even if there is residual when steam flows to the outlet of the condensing conduit, it will come into contact with the third side wall and get condensed, and drop into the discharging through hole. In addition, by providing the third side wall, the condensing conduit is separated from the inner chamber of the bottom lid so as to prevent steam from spilling out and affecting performance of electronic parts mounted in the inner chamber of the bottom lid.
In an embodiment, the cooling mechanism further comprises a lower passage groove formed at the upper surface of the bottom lid, the condensing skeleton covering an upper opening of the lower passage groove so as to form the condensing conduit.
Specifically, the lower passage groove is formed by a downwardly recessed inner surface of the lower lid, or by a protruding rib formed on the upper surface of the bottom lid.
In an embodiment, the condensing conduit extends in an arc shape along an edge of the bottom lid over an angle of 20 to 360 degrees. Due to the fact that the condensing conduit has a certain length of extension, steam can be gradually cooled down along a long path so that steam entering via the steam conduit is quickly condensed when passing through the condensing conduit, thus achieving the purpose of reducing the risk of scalds and thereby ensuring utilization safety.
Further, the condensing conduit comprises a plurality of condensing conduit branches, inlets of which are all in communication with the lower end of the steam conduit, so that steam can enter each condensing conduit branch after being distributed in the condensing conduit, achieving the purpose of quick condensing.
Specifically, the condensing conduit comprises a first condensing conduit branch and a second condensing conduit branch that extend in opposite directions from the lower end of the steam conduit.
In an embodiment, a first accommodating chamber and a second accommodating chamber that are sealed relative to each other are provided in the lid assembly, and a bottom wall of the lid assembly further comprises a liquid outlet that puts an inner chamber of the container and the first accommodating chamber in communication, a backflow opening that puts the inner chamber of the container and the second accommodating chamber in communication, and a steam vent that puts the inner chamber of the container and the second accommodating chamber in communication, the backflow opening being provided near the liquid outlet, the lid assembly being provided with an output control part capable of opening at the same time the liquid outlet and the backflow opening of the container and blocking at the same time the liquid outlet and the backflow opening of the container.
By providing the liquid outlet that puts the inner chamber of the container and the first accommodating chamber in communication, the backflow opening that puts the inner chamber of the container and the second accommodating chamber in communication, and the steam vent that puts the inner chamber of the container and the second accommodating chamber in communication at the bottom wall of the lid assembly, and providing the backflow opening near the liquid outlet, during use, steam in the inner chamber of the container can enter the second accommodating chamber via the steam vent and can be partly condensed in the second accommodating chamber. When a user presses down the output control part, the liquid outlet and the backflow opening are opened at the same time. While water is being poured out by tilting the container, condensed water inside the second accommodating chamber can flow into the inner chamber of the container via the backflow opening. Thus, timely discharge of condensed water is achieved, thereby preventing bacteria growth due to its long-term accumulation and ensuring drinking water hygiene.
In an embodiment, the liquid heating container further comprises a heating control part provided at the bottom of the container body and above the bottom lid, and an upper connector provided at the bottom of the container body and electrically connected to the heating control part; wherein the cooling mechanism is provided to extend on the bottom lid in a circumferential direction of the upper connector.
By providing the cooling mechanism around the upper connector, steam can be prevented from affecting electronic parts, such as the heating control assembly and the upper connector, while maximizing the steam cooling distance, which not only improves the steam cooling effect, but also guarantees the safety performance.

It should be noted that the position words such as "upper" and "lower" described in the embodiments of the present application are described in terms of perspectives actually illustrated, and should not be construed as limitations on the embodiments of the present application. Furthermore, in the context, it is also necessary to explain that when one element is referred to as being connected to another element, it can be either a direct connection or an indirect connection, unless it is expressly stated that one element is directly connected to the other element.
The terms such as "first" and "second" are used for descriptive purposes only, and should not be understood as indicating or implying relative importance or implying the number of technical features indicated. Thus, a feature defined by "first", "second" may expressly or implicitly include one or more of that feature. In the description of the present disclosure, unless stated otherwise, "a plurality" means two or more.
Specific embodiments of the present application are described in detail. Although some embodiments have been shown and described, those skilled in the art should understand that those embodiments can be modified and improved without departing from the principle and spirit of the present application, the scope of which is defined by the claims and their equivalents. In the liquid heating container according to the present application, the steam conduit is provided inside the handle, and steam created in the container body is guided to flow to a lower part of the liquid heating container, for example, to the bottom lid, by means of the steam conduit in the handle so as to discharge the steam from below. As the formed steam passage is located inside the liquid heating container, and discharge is realized from the bottom of the liquid heating container, it can not only improve the heat preservation effect of the liquid heating container, but also ensure that users will not be scalded during use as steam is not easily accessible to users during use.
In addition, to further reduce the temperature of the steam discharged, the present application further proposes to provide a cooling mechanism in the bottom lid of the liquid heating container to further cool down steam discharged into the bottom lid via the steam conduit so that the steam is condensed into liquid, further reducing the risk of scalding a user. The liquid heating container according to the present application is described in detail below in reference to the drawings.
As shown in Figs. 1 and 2, the present application provides a liquid heating container comprising a container body 10, a bottom lid 30 provided at the bottom of the container body 10, and a handle 40 provided at a side of the container body 10. A closed liquid storing chamber is formed inside the container body 10 which is provided with a steam outlet 20 in communication with the liquid storing chamber, a cooling mechanism 60 is provided inside the bottom lid 30, and a steam conduit 50 is provided inside the handle 40. In this embodiment, an upper end of the steam conduit 50 is in communication with the steam outlet 20, and a lower end of the steam conduit 50 extends into the bottom lid 30 and is in communication with the cooling mechanism 60. The bottom lid 30 is further provided with a discharging through hole 31 that enables condensed water formed by steam after being condensed by the cooling mechanism 60 to be discharged to the exterior of the bottom lid 30.
In the example illustrated, the container body 10 comprises a container 11 formed with an inner chamber that has an upper opening, and a lid assembly 12 that blocks the upper opening of the container 11 so as to together enclose and form the liquid storing chamber. An upper end of the handle 40 is connected with the lid assembly 12. Thus, the steam outlet 20 can be provided at the lid assembly 12. However, the location where the steam outlet 20 is provided is not limited thereto. In the event that the upper end of the handle 40 is connected with the container 11 , the steam outlet 20 can be provided at an upper side wall of the container 11 .
In the liquid heating container according to an embodiment of the present application, no steam vent is provided at the spout of the container boy 10, and a closed liquid storing chamber is formed inside the container body 10 which is provided with a steam outlet 20 in communication with the liquid storing chamber. During heating, steam inside the liquid storing chamber enters the steam conduit 50 via the steam outlet 20. The steam conduit 50 is provided inside the handle 40 with its upper end being in communication with the steam outlet 20 and its lower end extending into the bottom lid 30. As the steam conduit 50 is located inside the liquid heating container and not easily accessible by a user, it can be ensured that the user is not scalded during use, a completely safe contact is thus achieved. During use, steam produced from the liquid storing chamber of the container body 10 enters the steam conduit 50 via the steam outlet 20 and flows towards the bottom lid 30, the entire steam passage is located inside the liquid heating container, and steam does not emerge at easily accessible locations, such as at the spout at the top of the container body 10 or at the handle of the container. Thus, steam does not come into direct contact with a user during the course of flowing, which can reduce the risk of scalds. In addition, steam is able to enter the cooling mechanism 60 smoothly and be condensed into condensed water in the cooling mechanism 60. Even if condensed water formed from steam flows out of the liquid heating container, no risk of scalds exists. Compared to the prior art, the present application changes the flow path of steam (not emerging out of easily accessible locations, such as at the spout or at the handle) so as to reduce the risk of scalds, ensuring the utilization safety of a user, and, by providing the cooling mechanism 60 for fast cooling, further ensures the utilization safety of the user.
The cooling mechanism 60 according to an embodiment of the present application has a long extending structure, thus steam is able to be fully cooled and, after being fully cooled and condensed, flows out of the bottom lid 30. Hence, the impact of steam on heating control parts 110 such as NTC and strong current circuits located in the bottom lid 30 is sufficiently reduced, and the safety level of the product is improved.
In the liquid heating container according to an embodiment of the present application, the upper end of the handle 40 is connected with the lid assembly 12, and the steam outlet 20 can be formed at the lid assembly 12 so as to ensure that the effective accommodating volume of the inner chamber of the container 11 is not affected, and can be provided at a side of the lid assembly 12 close to the handle 40 so as to ensure that when pouring water, water will not be poured out from the inlet of the steam outlet 20 and cause a safety accident. In an embodiment, a safety valve can be provided at the inlet of the steam outlet 20 so as to close it when water is being poured out from the spout. Of course, in the event that the upper end of the handle 40 is connected with the container 11 , the steam outlet 20 of the present application can be formed at an upper side wall of the container 11 , specifically, at an upper side wall of the container 11 opposite the handle 40.
Figs. 1 and 2 show an example wherein the steam outlet 20 is formed at the lid assembly 12 which is provided with an internal passage so that the steam outlet 20 communicates with the inner chamber of the container 11 , the handle 40 and the spout are provided at opposite sides of the container 11 , and two ends of the handle 40 are connected respectively with the lid assembly 12 and the bottom lid 30.
In the embodiment, in the event that the bottom lid 30 has a sufficient thickness, the condensing conduit can be a conduit formed in an inner wall of the bottom lid 30. Specifically, a passage can be formed inside the bottom lid 30 as the condensing conduit. Considering the processing difficulty and processing efficiency in the actual production process, the condensing conduit according to an embodiment of the present application is a conduit enclosed by for example a baffle and the upper surface of the bottom lid. Here the shape of a cross-section of the conduit is not limited to a circular shape. A cross-section of the conduit according to the present application can be any polygonal, such as a square.
In the embodiment, the cooling mechanism 60 is a condensing conduit formed at the upper surface of the bottom lid 30 that has a first end and a second end opposite each other and serving as an inlet and an outlet of the condensing conduit, respectively. The inlet of the condensing conduit is located at the first end and is in communication with the lower end of the steam conduit 50. The bottom lid 30 is further provided with a discharging through hole 31 that puts the condensing conduit and the exterior of the bottom lid 30 in communication and thus enables condensed water to be discharged smoothly.
The bottom lid 30 of the present application can have a certain mounting inner chamber. Specifically, the upper surface of the bottom lid 30 is configured to be recessed so as to form the bottom lid 30 having a mounting inner chamber. The bottom lid 30 comprises a bottom wall, a side wall, and a mounting inner chamber enclosed by the bottom wall and the side wall. The cooling mechanism 60 can be formed at an upper surface of the bottom wall, or at an inner surface of the side wall, and located in the mounting inner chamber. Compared to forming the condensing conduit at the side wall, forming the condensing conduit at the upper surface of the bottom wall is relatively easy and the post-mounting stability can be ensured.
Fig. 3 shows an example wherein the cooling mechanism 60 is formed at the upper surface of the bottom wall. In the embodiment, the cooling mechanism 60 is a condensing conduit formed at the upper surface of the bottom wall of the bottom lid 30, the lower end of the steam conduit 50 extends to be just above the inlet of the condensing conduit and is in communication with it, and the discharging through hole 31 is provided in the bottom wall of the bottom lid 30, communicates with the exterior, and is located below the outlet of the condensing conduit. In the liquid heating container according to an embodiment of the present application, as the condensing conduit has an outlet and an inlet, and the discharging through hole 31 is provided below the outlet of the condensing conduit, it is ensured that condensed water generated in the condensing conduit can be timely discharged to the outside of the bottom lid 30, so as to avoid the accumulation of condensed water inside the bottom lid 30 and thus affect the steam condensation. During operation, the steam enters the cooling mechanism 60 through the inlet and outlet of the condensing conduit in sequence, and then flows to the outside of the bottom lid 30 through the discharging through hole 31 in the bottom lid 30.
In the embodiment, the outlet of the condensing conduit is located at a second end of the condensing conduit, and, in the direction from the inlet to the outlet, the width and height of the condensing conduit gradually decrease, in other words, in the direction from the inlet to the outlet, the “diameter” of the condensing conduit gradually decreases.
In the liquid heating container according to an embodiment of the present application, since the width and height of the condensing conduit gradually decrease in the direction from the inlet to the outlet, steam will hit the inner wall of the condensing conduit when flowing therein and rapidly form condensed water due to the relatively low temperature of the innerwall.
In the embodiment, the cooling mechanism 60 can comprise a condensing skeleton 61 extending from the lower end of the steam conduit 50 along the upper surface of the bottom lid 30. The condensing skeleton 61 is in the shape of an oblong bar and has a first end and a second end opposite each other. The first end of the condensing skeleton 61 is connected with the lower end of the steam conduit 50, a lower surface of the condensing skeleton 61 and the bottom lid 30 together enclose and form the condensing conduit, and the discharging through hole 31 can be located below an outlet of the second end of the condensing skeleton 61 or in communication with the outlet of the second end of the condensing skeleton 61.
In a first embodiment according to the present application, the condensing conduit forms an upper passage groove 62 by the recessed lower surface of the condensing skeleton 61. A lower edge of the upper passage groove 62 abuts against the upper surface of the bottom lid 30 to form the condensing conduit that opens at the second end and the second end of the condensing conduit is located above the discharging through hole 31 , so that steam has been fully condensed after flowing through the entire condensing conduit.
Fig. 3 shows an example of the first embodiment of the present application. In the specific embodiment, the lower surface of the condensing skeleton 61 is recessed so as to form an upper passage groove 62 that opens downward. A lower edge of the upper passage groove 62 abuts against the upper surface of the bottom lid 30 to form the condensing conduit. The second end of the condensing conduit is in the shape of an opening and is located above the discharging through hole 31. Specifically, the condensing skeleton 61 comprises a condensing skeleton top wall 611 in the shape of an oblong bar, and a first side wall 612 and a second side wall 613 connected to two sides of the top wall 611 , respectively. A lower edge of the first side wall 612 and a lower edge of the second side wall 613 both abut against the upper surface of the bottom lid 30 such that the condensing conduit is formed between the top wall 611 , the first side wall 612, and the second side wall 613 of the condensing skeleton and the upper surface of the bottom lid 30.
In the liquid heating container according to the first embodiment of the present application, since the second end of the condensing conduit is open, a small amount of steam may spill out and affect the safety of electronic components such as heating control parts inside the bottom lid 30. Therefore, in a second embodiment according to the present application, on the basis of the first embodiment, the condensing skeleton 61 can further comprise a third side wall 614 that blocks the opening of the second end of the condensing skeleton 61 so as to form a condensing conduit with the second end closed. With such provisions, electronic components such as a heating control part 110 are completely isolated from the condensing conduit, increasing gas-tightness of the condensing conduit and further improving the safety performance and service life of electronic components.
Fig. 4 shows a partial structure of the liquid heating container according to the second embodiment of the present application. In the embodiment shown in Fig. 4, in addition to the features described in the first embodiment, the condensing skeleton 61 further comprises a third side wall 614 that blocks the opening of the second end of the condensing skeleton 61 , and the condensing skeleton 61 and the bottom lid 30 form a closed condensing conduit in communication with the discharging through hole 31. In the liquid heating container according to the present embodiment, by providing the third side wall 614, even if there is some residual steam when it flows to the outlet of the condensing conduit, it will be condensed by coming into contact with the third side wall 614 due to the relatively low temperature of an inner wall of the third side wall 614 and drop into the discharging through hole 31.
Figs. 6 to 8 show an example of a third embodiment of the present application. In the specific embodiment, in addition to the upper passage groove 62 that opens downward formed by the recessed lower surface of the condensing skeleton 61 , the cooling mechanism 60 further comprises a lower passage groove 63 formed at the upper surface of the bottom lid 30. The condensing skeleton 61 covers an upper opening of the lower passage groove 63 so as to form a condensing conduit in communication with the discharging through hole 31. Specifically, the lower passage groove 63 is formed by a protruding rib formed at the upper surface of the bottom lid 30, or by a groove formed in the upper surface of the bottom lid 30. Specifically, the lower passage groove 63 can be provided at a location at the upper surface of the bottom lid 30 that corresponds to the condensing skeleton 61.
Based on the various embodiments described above, the condensing conduit according to the present application can have at least one of the upper passage groove 62 and the lower passage groove 63. By providing a condensing conduit with an appropriate “diameter,” the objective that the condensing conduit facilitates the condensing of steam is achieved. The cross-section of the condensing conduit in an embodiment of the present application can be formed in the shape of a circle or a square, and the condensing conduit can extend on the edge of the bottom lid, for example, extending in the shape of a spiral or an arc.
Fig. 9 shows an example wherein the condensing conduit extends along an edge of the bottom lid in the shape of an arc. Specifically, the angle of extension R can be 20 to 360 degrees. Preferably, it can be 40 to 180 degrees.
In the liquid heating container according to an embodiment of the present application, by providing a condensing conduit having a certain extension length, the temperature of steam can be reduced gradually in a relatively long path so that steam entering from the steam conduit 50 is rapidly condensed when passing through the condensing conduit and thus the purpose of reducing the risk of scalds is achieved, thereby ensuring utilization safety.
In the present application, the cooling mechanism 60 can be formed by one condensing conduit that is formed by one condensing skeleton. However, to increase the rate of steam condensation and ensure that all the steam is condensed and the condensed water flowing out has a relatively low temperature, a plurality of condensing conduit branches can be provided as the cooling mechanism 60.
In an embodiment, the condensing mechanism is formed by a plurality of condensing conduit branches, the inlets of which are all in communication with the lower end of the steam conduit 50 so that steam can branch out in the condensing conduit and enter different condensing conduit branches, achieving the purpose of rapid condensing.
Specifically, the condensing conduit can comprise a first condensing conduit branch and a second condensing conduit branch that extend in opposite directions from the lower end of the steam conduit 50. After the cooling mechanism 60 has finished cooling the steam, the condensed water formed needs to be discharged out of the bottom lid 30. In order to enable the condensed water to be discharged out of the condensing conduit easily, a drainage slot can be provided at the outlet of each condensing conduit branch so that the condensed water easily flows out.
As shown in Fig. 8, the drainage slots 64 are inclined downward towards the exterior of the bottom lid 30 so that condensed water flows smoothly to the exterior of the bottom lid 30 via the discharging through holes 31 .
In an embodiment of the present application, the steam conduit can be a pipe that has only two end openings or a passage formed by combining two parts, or can be formed directly by the inner chamber of the handle. For example, in the event that the handle 40 has a sufficient thickness, the steam conduit can be formed directly by means of the handle 40. But in the case of a large amount of steam, the handle 40 is prone to deformation due to long-term heating and there exists also a risk of scalding a user. As to a steam conduit formed by an entire pipe, when it is connected to the steam outlet 20 and the cooling mechanism 60, there are great limitations and the installation is inconvenient. Therefore, the present application preferably adopts a steam conduit 50 formed by combining two parts. The tightness of the combining can be ensured by providing a multi-level snap-fit engagement and sealing gaskets at the location of the combining. In an embodiment, the steam conduit 50 formed can be provided in the inner chamber of the handle 40. As the steam conduit 50 does not come into contact with the inner chamber of the handle 40, a poor heat conductor such as air may be stored between the steam conduit 50 and the inner wall of the handle. Therefore, the temperature of the steam inside the steam conduit 50 will not affect the temperature of the handle 40.
Still in reference to Figs. 1 and 2 showing an example wherein the steam conduit is formed by combining two parts, the steam conduit 50 comprises an outer lid 51 and an inner lid 52 provided at an inner side of the outer lid 51. The steam conduit 50 is formed by combining the outer lid 51 and the inner lid 52. As the steam conduit 50 comprises an obstacle-free passage, for example, there is no baffle that blocks steam in the steam conduit 50, the steam conduit 50 has good air passage performance, thus steam can enter the cooling mechanism 60 smoothly and be condensed therein.
In an embodiment, one of the outer lid 51 and the inner lid 52 can be fixed to the handle 40 so that during use, it is more stable and reliable. The steam conduit 50 can be at a preset distance from the handle 40 (so long as they do not come into direct contact) to ensure that the temperature of the handle 40 will not be too high. In addition, the steam conduit 50 can be of a similar shape as that of the handle 40, and located in the inner chamber of the handle 40. With such provisions, the structure is simple and space is saved. A sealing sleeve capable of ensuring the tightness of the steam conduit 50 can be further provided at an outer side of the steam conduit 50 so as to prevent steam from leaking during the course of flowing in the steam conduit 50.
In an embodiment, the upper end of the steam conduit 50 forms an air inlet 53, the lower end of the steam conduit 50 forms an air outlet 54, and each condensing conduit branch is in communication with the air outlet 54.
Still in reference to Fig. 2, the outer lid 51 and the inner lid 52 are combined to form the steam conduit 50. The air inlet 53 is formed at an upper end of the inner lid 52. A side face of the inner lid 52 is depressed inward to form a guiding groove 523 extending upward to be in communication with the air inlet 53 and downward to form the air outlet 54 when combined with the outer lid 51. When the outer lid 51 covers the inner lid 52, the steam conduit 50 is formed between the outer lid 51 and the inner lid 52.
In the liquid heating container according to the present application, the lower end of the steam conduit 50 can be connected to the cooling mechanism 60 in an integral manner, or in a snap-fit manner.
Fig. 5 shows an example wherein the lower end of the steam conduit 50 and the cooling mechanism 60 are connected integrally. With the lower end of the steam conduit 50 and the cooling mechanism 60 formed integrally during manufacturing, good tightness during the steam flowing can be ensured.
Fig. 6 shows an example wherein the lower end of the steam conduit 50 is connected in a snap-fit manner to the cooling mechanism 60. The formed reliable structure in which the outer lid 51 , the inner lid 52, and the condensing skeleton closely cooperate with each other ensures that the junction between the steam conduit 50 and the cooling mechanism 60 will not be deformed by the heat of the steam to affect the tightness of the connection. When a snap-fit connection is used, a sealing gasket can further be provided at the junction to achieve a good sealing effect.
In an embodiment, the liquid heating container further comprises a heating control part 110 provided at the bottom of the container body 10 and located above the bottom lid 30. The lower end of the steam conduit 50 extends into a region of the bottom lid 30 at the bottom of the heating control part 110 and is at a sufficient preset distance from the heating control part 110, or bypasses the heating control part 110, so that steam is distant from the heating control part 110 and will not affect it. Thus, the utilization safety and service life of the liquid heating container can be ensured. In an embodiment, as shown in Figs. 1 to 2, the liquid heating container further comprises an upper connector 111 provided at the bottom of the container body 10 and electrically connected to the heating control part 110, and the cooling mechanism is provided to extend on the bottom lid 30 in the circumferential direction of the upper connector 111. In this case, the cooling mechanism 60 is provided to surround the upper connector 111 , which makes it possible to avoid the impact of the steam on electronic elements such as the heating control assembly and the upper connector while maximizing the cooling distance of the steam. Not only the steam cooling effect is improved, but also the safety performance is guaranteed.
In an embodiment, the liquid heating container further comprises a power source base 120 having a lower connector and provided below the bottom lid 30. The lower connector supplies power to the heating control part 110 via the lower part of the bottom lid 30. Generally, the lower connector of the power source base 120 protrudes from the upper surface of the power source base 120 by a preset height so as to ensure that water in the container 11 , after spilling out, will not flow onto the lower connector and cause a short circuit of the power source. The locations of the discharging through holes 31 in the bottom lid will be arranged to avoid the junction between the upper and lower connectors. Therefore, even if a small amount of condensed water is discharged out of the bottom lid 30 via the discharging through holes 31 , the safety performance of the electrical connection of the power source base 120 will not be affected.
As shown in Fig. 10, a first accommodating chamber 71 and a second accommodating chamber 72 that are sealed relative to each other are provided in the lid assembly 12. A bottom wall of the lid assembly 12 further comprises a liquid outlet 73 that puts the inner chamber of the container 11 and the first accommodating chamber 71 in communication, a backflow opening 74 that puts the inner chamber of the container 11 and the second accommodating chamber 72 in communication, and a steam vent 80 that puts the inner chamber of the container 11 and the second accommodating chamber 72 in communication. The backflow opening 74 is provided near the liquid outlet 73, and the lid assembly 12 is provided with an output control part 75 capable of opening the liquid outlet 73 and the backflow opening 74 at the same time and blocking the liquid outlet 73 and the backflow opening 74 at the same time.
In an embodiment, the lid assembly 12 comprises an upper lid 121 and a lower lid 122 that are combined with each other. An upper surface of the lower lid 122 is provided with a partitioning wall 123 that abuts against a lower surface of the upper lid 121 and partitions an accommodating space between the upper lid 121 and the lower lid 122 into the first accommodating chamber 71 and the second accommodating chamber 72. The liquid outlet 73, the steam vent 80, and the backflow opening 74 are all provided in the lower lid 122.
Specifically, the partitioning wall 123 can be integrally formed on the upper surface of the lower lid 122, and a groove can be correspondingly provided in the lower surface of the upper lid 121 in which an upper end of the partitioning wall 123 can be engaged in a snap-fit manner. In an embodiment, at the junction between the upper lid 121 and the lower lid 122, corresponding sealing means, such as a sealing ring, can be further provided, so as to partition the accommodating space between the upper lid 121 and the lower lid 122 into the first accommodating chamber 71 and the second accommodating chamber 72 formed as two chambers sealed relative to each other.
In an embodiment, the backflow opening 74 is provided at the side of the partitioning wall 123 facing the second accommodating chamber 72 and located at the edge of the liquid outlet 73. The output control part 75 comprises a valve plug 751 capable of moving up and down and comprising a valve plug body, which can be in the shape of a plate, for example, a circular plate, and is located below the liquid outlet 73 and capable of moving upward to block the liquid outlet 73 and the backflow opening 74 at the same time and moving downward to open the liquid outlet 73 and the backflow opening 74 at the same time. In an embodiment of the present application, a sealing ring 752 can be further sleeved at the outer side of the valve plug 751 to ensure the reliability of the blocking of the liquid outlet 73 and the backflow opening 74.
In an embodiment of the present application, during use, when the valve plug body of the valve plug 751 is pressed upward against the lower surface of the lower lid 122 and cooperates tightly with a lower part of the liquid outlet 73 and the backflow opening 74, the liquid outlet 73 and the backflow opening 74 are both sealed. When the liquid outlet 73 is sealed, steam and liquid inside the container body will not come out of the liquid outlet 73, effectively preventing a user from being scalded. Meanwhile, the backflow opening 74 is also sealed by the valve plug body so that steam and liquid will not enter the lid assembly 12 via the backflow opening 74, either.
In the liquid heating container according to an embodiment of the present application, as the backflow opening 74 is provided at the side of the partitioning wall 123 facing the second accommodating chamber 72 and at the edge of the liquid outlet 73, the liquid outlet 73 and the backflow opening 74 are relatively close to each other and can be controlled synchronously by one valve plug 751 , which is more convenient.
In an embodiment, the liquid outlet 73 and the backflow opening 74 are provided to be opposite each other. When pouring water, the backflow opening 74 is in a relatively low position so that condensed water in the second accommodating chamber 72 can be all discharged easily via the backflow opening 74.
In an embodiment, in order to more thoroughly discharge water accumulated in the second accommodating chamber, the backflow opening 74 is located at the lowest point of the bottom wall of the second accommodating chamber 72.
In the liquid heating container according to an embodiment of the present application, by positioning the backflow opening 74 at the lowest point of the bottom wall of the second accommodating chamber 72, i.e., in a relatively low position, condensed water accumulated in the second accommodating chamber 72 will converge at the periphery of the backflow opening 74 so that when the container body 10 is in an upright state, so long as the valve plug 751 is pressed downward without tilting the container body 10, condensed water in the second accommodating chamber 72 will flow out of the backflow opening 74 and then be removed from the container, which ensures a full discharge of the condensed water and thus avoids long-term accumulation of the condensed water that would affect water drinking health and hygiene.
In the liquid heating container according to an embodiment of the present application, a steam passage can be provided at the lid assembly 12 so that steam in the container 11 enters the steam conduit 50 in the handle 40 via the steam outlet 20 and is discharged from the bottom lid 30 of the container. However, when the liquid heating container is hit by accident and falls overs during use, liquid in the container will flow into the bottom lid 30 along the steam conduit 50 and thus damage electronic assemblies in the bottom lid 30. Therefore, to avoid such a risk of damaging electronic assemblies, the present application further provides an anti-falling structure so that in the event that the liquid heating container falls over, it not only ensures proper steam pressure relief, but also prevents liquid from flowing into the bottom lid. The anti-falling structure in the liquid heating container according to an embodiment of the present application will be described below in detail in reference to Figs. 10 to 13. The anti-falling structure is provided in the lid assembly 12 of the liquid heating container according to an embodiment of the present application. As shown in Figs. 10 to 12, the lid assembly 12 comprises an upper lid 121 and a lower lid 122 that are combined together to form a first accommodating chamber 71 and a second accommodating chamber 72. A steam vent 80 is formed in the lower lid 122. The steam vent 80 is in communication with the second accommodating chamber 72 so that steam in the container body 10 can enter the second accommodating chamber 72 via the steam vent 80.
In an embodiment, as shown in Fig. 11 , the steam vent 80 comprises a first steam vent 81 , the liquid heating container further comprises a venting line 90 provided in the second accommodating chamber 72, a lower end of the venting line 90 being connected to the first steam vent 81. Steam in the inner chamber of the container 11 enters the second accommodating chamber 72 via the venting line 90 through the steam vent 80 and flows to the steam outlet 20, so that steam generated in the inner chamber of the container 11 smoothly enters the steam conduit 50 in the handle 40 via the steam outlet 20, thus achieving internal pressure relief of the container 11.
In an embodiment, the venting line 90 comprises an intake pipe 91 , a connecting pipe 92, a sealing pipe 93, and an exhaust pipe 94 that are connected end to end in sequence. The end of the intake pipe 91 that is not connected to the connecting pipe 92 is in communication with the first steam vent 81 , and the end of the exhaust pipe 94 that is not connected to the sealing pipe 93 serves as an outlet 941 of the entire venting line 90.
In an embodiment of the present application, steam in the inner chamber of the container 11 enters sequentially the intake pipe 91 , the connecting pipe 92, a first sealing pipe section 931 , a second sealing pipe section 932, and the exhaust pipe 94 via the first steam vent 81 , and is discharged into the second accommodating chamber 72 via the outlet 941 of the exhaust pipe 94. Therefore, steam will be collected in the second accommodating chamber 72 and enter the steam conduit 50 in the handle 40 via the steam outlet 20.
In an embodiment, the sealing pipe 93 comprises a first sealing pipe section 931 and a second sealing pipe section 932 connected in communication with each other. The first sealing pipe section 931 is connected in communication with the connecting pipe 92, and the second sealing pipe section 932 is connected in communication with the exhaust pipe 94. The liquid heating container further comprises a mobile sealing member 100 provided in the second sealing pipe section 932, which can be a bead capable of rolling in the second sealing pipe section 932 and is spaced apart from an inner side wall of the second sealing pipe section 932. When the bead rolls to the end of the exhaust pipe 94 that is connected to the second sealing pipe section 932, it is capable of blocking the exhaust pipe 94 so as to block the venting line 90.
In the liquid heating container according to an embodiment of the present application, the sealing pipe 93 is provided to comprise the first sealing pipe section 931 and the second sealing pipe section 932 connected in communication with each other and the mobile sealing member 100 is provided in the second sealing pipe section 932 which can serve as a course guiding chamber of the mobile sealing member 100. Thus, after the liquid heating container falls over, under the effect of gravity, the mobile sealing member 100 will quickly respond and roll to the end of the second sealing pipe section 932 that is connected to the exhaust pipe 94 so as to achieve the purpose of blocking the venting line 90. During normal use, as there is a gap between the bead and the second sealing pipe section 932 capable of letting air pass, the bead can be placed in the second sealing pipe section 932 to ensure that the venting line 90 can perform normal venting and pressure relief.
In the present application, the venting line 90 can be configured as a plurality of interconnected sub-pipes so as to facilitate the formation of a bent structure, for example, a U-shaped structure, which makes it convenient to provide the bead to achieve the purpose of blocking or unblocking under the effect of gravity. In addition, in order to ensure the sealing of the connection between different sub-pipes, corresponding sealing means, such as a sealing ring or sealing glue, can be provided at a connecting end of each sub-pipe.
In an embodiment, the end of the exhaust pipe 94 that is connected to the second sealing pipe section 932 is in the form of a tapered structure that gradually tapers and has two opposite ends, the bead being capable of blocking a tapered opening located at one end of the tapered structure. As shown in the example illustrated in Fig. 13, the bead can block the tapered opening that has a smaller diameter in the tapered structure. In an embodiment, the second sealing pipe section 932 can be sleeved to the outer side of the exhaust pipe 94 and thus a course guiding chamber of the bead can be formed by means of the tapered structure of the exhaust pipe 94.
In the liquid heating container according to an embodiment of the present application, the end of the exhaust pipe 94 that is connected with the second sealing pipe section 932 is configured to be a tapered structure which gradually tapers and in which the bead is capable of rolling with a gap formed between it and the inner wall surface of the tapered structure. When the bead rolls to the side of the tapered opening of the tapered structure that is far away from the second sealing pipe section 932 and abuts against it, the bead can be partly located in the tapered opening. On one hand, it can be ensured that the bead fully seals the tapered opening of the second sealing pipe section 932. On the other hand, the tapered opening can limit the position of the bead and fix it to a certain extent, improving sealing stability.
In an embodiment of the present application, a corresponding pad can be provided in the lower lid 122 based on actual circumstances, so that during normal use, the bead will roll into the second sealing pipe section 932 under the effect of gravity. For example, a pad is provided at the lower side of the exhaust pipe 94 so that an inclination angle facilitating rolling is formed between the direction of extension of the exhaust pipe 94 and a horizontal plane, such that during normal use, the bead can roll into the second sealing pipe section 932, ensuring normal venting and pressure relief. In an embodiment, in addition to the first steam vent 81 , the steam vent 80 further comprises a second steam vent 82, and in addition to the first sealing pipe section 931 and the second sealing pipe section 932 in communication with each other, the sealing pipe 93 further comprises a third sealing pipe section 933 in communication with the first sealing pipe section 931 and the second sealing pipe section 932 and capable of being connected to the second steam vent 82.
In the liquid heating container according to an embodiment of the present application, by providing the first steam vent 81 and the second steam vent 82, the size of each steam vent 80 can be reduced as much as possible provided that a preset steam discharge quantity is ensured. As such, excessive size that makes it easy for liquid to spill out from the steam vent is avoided. In addition, by providing a relatively large number of steam vents 80 at the lower lid 122, steam at various locations inside the container 11 can be distributed so as to achieve the purpose of timely discharge.
In an embodiment, the lid assembly 12 is further provided with a water pouring opening 21 and is symmetric relative to the connecting line that connects the water pouring opening 21 and the handle 40. There are at least two venting lines 90 and they are provided symmetrically relative to the connecting line. There are at least two first steam vents 81 which are provided symmetrically relative to the connecting line, near an edge of the lower lid 122, and connected to a corresponding intake pipe 91 respectively. The inlet of each venting line 90 is in communication with a corresponding first steam vent 81 and its outlet is in communication with the second accommodating chamber 72.
In an embodiment, each venting line 90 is a U-shaped line, the base of which is closer to the connecting line than its opening part and provided to face the handle 40. There are at least two second steam vents 82 which are provided symmetrically relative to the connecting line, closer to the connecting line than the first steam vents 81 , and connected to a corresponding third sealing pipe section 933, respectively.
In the liquid heating container according to an embodiment of the present application, a plurality of venting lines 90 are provided and they are provided symmetrically relative to the connecting line, each venting line 90 being U-shaped and provided near an edge of the lower lid 122, and the inlets of the venting lines 90 being provided at an edge of the lower lid 122. Thus, the inlet and outlet of a venting line 90 can be located at the same side of the venting line 90. When the liquid heating container has fallen over, the venting line 90 located below the liquid level is blocked so as to prevent high temperature liquid from leaking, while the inlet of the venting line 90 located above the liquid level is located at an edge at the highest position of the lid assembly 12, which facilitates the relief of steam pressure in the inner chamber of the container 11 , better prevents steam pressure from ejecting water out of the venting line 90 and avoids dangerous situations such as explosions due to excessive pressure in the inner chamber of the container 11 .
Fig. 12 shows an example of the structure of the venting line. In the example shown in Fig. 12, there are two venting lines 90, each being a U-shaped line. The inlet (i.e., air admitting end) and outlet (i.e. air discharging end) of each venting line 90 are both located at an edge of the lower lid 122 and at the same side of the connecting line.
Due to structural reasons, when the liquid heating container of the present application falls over, it will fall over in a certain direction. Generally, there are two fallen-over states. It can fall over in the direction as shown in Fig. 13, or in a mirror direction relative to that shown in Fig. 13.
Fig. 13 shows an example in which the liquid heating container has fallen over. In the example shown in Fig. 13, provided that the inner chamber of the container 11 contains a normal quantity of liquid, after the liquid heating container has fallen over, the mobile sealing member 100 of group B located below will roll to a blocking position. At this moment, the first steam vent 81 and the second steam vent 82 of group B are generally below the liquid level. As the mobile sealing member 100 is in the blocking position, liquid in the inner chamber of the container 11 will not spill out. At this moment, the U-shaped venting line 90 of group B is in a closed state. Meanwhile, the mobile sealing member 100 of group A is not in a blocking position, the U-shaped venting line 90 of group A is thus in an unblocked state, and the first steam vent 81 of group A is located at the highest position of the lower lid 122, generally above the liquid level in the inner chamber of the container 11. When there is a steam pressure inside the liquid heating container, steam will enter the U-shaped venting line 90 of group A via the first steam vent 81 and be discharged via the outlet 941. In addition, after the pressure in the inner chamber of the container 11 is released, liquid in the inner chamber might enter the venting line 90 via the second steam vent 82, but as the outlet 941 is also located at the highest position and above the liquid level in the inner chamber of the container 11 , liquid will not spill out from the outlet 941 either. Therefore, the venting line 90 of group A is in an open state, which makes it possible to release the pressure in the inner chamber of the container 11 and ensure that liquid in the inner chamber of the container 11 will not spill out.
By means of the above-described anti-falling structure, even if the liquid heating container has fallen over, liquid can be prevented from flowing into the bottom lid via the steam vent 80 to cause unnecessary scalds, and pressure can be timely released so as to avoid dangerous situations such as explosions due to excessive pressure in the inner chamber of the container 11. Although the embodiments of the present application have been described in detail above, those skilled in the art may make various modifications and variations to the embodiments of the present application without departing from the spirit and scope of the present application. However, it should be understood that, to those skilled in the art, such modifications and variations will still fall within the spirit and scope of the embodiments of the present application as defined by the claims.
