DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

Example:

Referring to FIGS. 1 to 7 , a first aspect of the present embodiment provides a liquid storage container 100 , including: a container body, the container body is provided with a liquid storage space 110 and an opening communicating with the liquid storage space 110 , the opening being used for connecting and cooperating with an external component;

A flexible wall 200 is provided on at least the area of the inner wall of the container body facing the liquid storage space 110 . The flexible wall 200 has a pore structure to provide a pressure relief space for the fluid in the liquid storage space 110 when it expands due to heat.

In this embodiment, a flexible wall 200 with a porous structure is provided on the inner wall of the container body facing the liquid storage space 110. When the fluid in the liquid storage space 110 expands due to heat, the pressure inside the liquid storage space 110 increases. The deformation of the flexible wall 200 and the porous structure of the flexible wall 200 can provide an elastic pressure relief space for the fluid, thereby reducing the pressure inside the liquid storage space 110. The pressure relief space can maintain a certain pressure in the liquid storage space 110 at different temperatures, greatly reducing the risk of leakage at the connection between the opening of the container body and the external parts, and/or other porous locations of the external parts and the liquid storage container 100.

As an example, the fluid in the liquid storage space 110 includes liquid and/or gas. Specifically, the liquid in the liquid storage space 110 is an atomized liquid.

Furthermore, the flexible wall 200 includes a first flexible layer 210 integrally formed on the inner wall of the container body, and the pore structure includes a plurality of first holes 211 spaced apart on the first flexible layer 210 , and the first holes 211 constitute at least a portion of the pressure relief space.

As shown in FIG. 1 and FIG. 2 , it should be understood that the first flexible layer 210 may cover the entire inner wall of the container body, or may only cover a portion of the inner wall of the container body. If the first flexible layer 210 covers a portion of the inner wall of the container body, the first flexible layer 210 covers at least a portion of the area on the inner wall of the container body where the liquid storage space 110 is provided. As an example, the area of the area on the inner wall of the container body where the liquid storage space 110 is provided and covered by the first flexible layer 210 may account for at least 20%, 30%, 35%, 40%, 50% or more of the area of the area on the inner wall of the container body where the liquid storage space 110 is provided. The area covered by the first flexible layer 210 on the inner wall of the container body should be such that the first flexible layer 210 has a sufficient area for setting the pore structure, thereby ensuring that the first flexible layer 210 can form a sufficient pressure relief space.

A plurality of first holes 211 are disposed in a region of the first flexible layer 210 that covers the inner wall of the container body and where the liquid storage space 110 is disposed.

Specifically, as shown in FIG1 , as an example, the first flexible layer 210 covers the entire inner wall of the container body, and a plurality of first holes 211 are uniformly arranged in an array in an area where a portion of the liquid storage space 110 is provided on the inner wall of the container body covered by the first flexible layer 210. A plurality of first holes 211 are uniformly arranged in an array in an area where a portion of the liquid storage space 110 is provided on the inner wall of the container body covered by the first flexible layer 210, and the first holes 211 and the flexible wall 200 both provide a pressure relief space for the fluid, and can better adjust the pressure in the liquid storage space 110, and effectively reduce the risk of leakage of the liquid storage container 100.

It can be understood that the plurality of first holes 211 may also be irregularly distributed on the first flexible layer 210. For example, the first flexible layer 210 may have a dense area with a large number of first holes 211 and a sparse area with a small number of first holes 211. The temperature distribution in different areas on the container body may be different. The dense area and the sparse area may be set correspondingly according to the temperature distribution of the container body caused by the external ambient temperature. For example, the dense area corresponds to the high temperature area on the container body, and the sparse area corresponds to the low temperature area on the container body, so that the flexible wall 200 as a whole has a better pressure relief and buffering effect.

Further, as shown in FIGS. 1-2 , the first hole 211 penetrates to the side of the first flexible layer 210 facing the liquid storage space 110 , and the first hole 211 is a capillary hole so that the fluid in the liquid storage space 110 enters the first hole 211 when it expands due to heat.

In the present embodiment, the first hole 211 is a capillary pore, which generally refers to a pore with an inner diameter equal to or less than 1 mm, and the liquid fluid in the liquid storage space 110 generates a capillary phenomenon in the capillary pore. Under normal temperature conditions, the pressure inside the liquid storage space 110 is equivalent to the external atmospheric pressure, and the liquid fluid in the liquid storage space 110 does not infiltrate the first hole 211, and the liquid fluid can be located outside the first hole 211. Changes in ambient temperature cause the temperature of the liquid storage space 110 in the liquid storage container 100 to rise, and both the gaseous and liquid fluids in the liquid storage space 110 expand due to the heat, and the pressure in the liquid storage space 110 increases, and the liquid fluid enters the first hole 211. When the temperature of the liquid storage space 110 returns to normal temperature, the fluid entering the first hole 211 flows back into the liquid storage space 110.

As an example, the first hole 211 may be a through hole that penetrates the first flexible layer 210 in the thickness direction, or a blind hole that penetrates only one side of the first flexible layer 210 facing the liquid storage space 110. The first hole 211 may be a tapered hole, a stepped hole, or a hemispherical hole with a gradually decreasing hole diameter in the thickness direction, wherein the hole diameter of the first hole 211 on the side close to the liquid storage space 110 is larger than the hole diameter on the side away from the liquid storage space 110. This arrangement facilitates the integral molding of the first flexible layer 210 having the first hole 211 on the inner wall of the container body, and also facilitates the fluid to enter and exit the first hole 211 due to temperature changes.

In this embodiment, as shown in FIGS. 1 to 4 , the first hole 211 is a through hole that penetrates the first flexible layer 210 in the thickness direction, and the first hole 211 is a cylindrical capillary hole.

Further, as shown in FIGS. 1 to 4 , the diameter of the first hole 211 is 0.2 mm-0.8 mm.

Further, as shown in Figures 1 to 4, the first flexible layer 210 has an integrally connected pressure relief area 210b and a sealing area 210a, the pressure relief area 210b is arranged on the inner wall of the container body facing the liquid storage space 110, and the sealing area 210a extends to the opening end of the container body for sealing with external components, wherein the first hole 211 is arranged on the pressure relief area 210b.

The open end of the traditional liquid storage container 100 is sealed with external components by a silicone part (such as an O-ring), but as shown in FIGS. 1 and 2 , in some embodiments of the present invention, the first flexible layer 210 has an integrally connected pressure relief area 210 b and a sealing area 210 a, and the sealing area 210 a extends to the open end, cleverly utilizing the ductility of the flexible wall 200 so that the flexible wall 200 can have the same sealing effect as the silicone part. This sealing method has low requirements on process precision, simple process, and convenient assembly, which reduces the cost of sealing the open end of the liquid storage container 100 with external components and also reduces the risk of fluid overflowing the liquid storage space 110.

Furthermore, as shown in FIGS. 3-4 , the flexible wall 200 further includes a second flexible layer 220 disposed on one side of the first flexible layer 210 along the thickness direction to reduce heat transfer of the flexible wall 200 from the container body to the liquid storage space 110 .

With such arrangement, on the one hand, the second flexible layer 220 can produce elastic deformation to provide an elastic pressure relief space for the fluid, so that a certain pressure is maintained in the liquid storage space 110 at different temperatures. On the other hand, the second flexible layer 220 increases the thickness of the flexible wall 200, which can reduce the external heat transferred to the liquid storage space 110 through the container body, and reduce the influence of the external ambient temperature on the fluid in the liquid storage space 110. The above two aspects can reduce the risk of leakage at the connection between the opening of the container body and the external component, or other locations with pores between the external component and the liquid storage container 100.

As an example, as shown in Figures 3 and 4, in some embodiments, the second flexible layer 220 is arranged on the side of the first flexible layer 210 facing the liquid storage space 110, and the first flexible layer 210 and the second flexible layer 220 are stacked in sequence on the side wall in the container body, forming a structure in which the middle layer has a columnar cavity. The fluid that expands due to the increase in temperature in the liquid storage space 110 due to the influence of ambient temperature can be squeezed toward the second flexible layer 220, so that the second flexible layer 220 is partially recessed into the first hole 211 of the first flexible layer 210, thereby balancing the pressure in the liquid storage space 110.

In other embodiments, the second flexible layer 220 may also be disposed between the first flexible layer 210 and the inner wall of the container body.

Further, as shown in FIGS. 1 to 4 , the first flexible layer 210 has an integrally connected pressure relief area 210 b and a sealing area 210 a , the pressure relief area 210 b is arranged on the inner wall of the container body facing the liquid storage space 110 , the sealing area 210 a extends to the opening end, and the first hole 211 is at least arranged in the pressure relief area 210 b ;

The second flexible layer 220 is disposed on a side of the first flexible layer 210 facing the liquid storage space 110. The second flexible layer 220 at least partially covers the pressure relief area 210b and the sealing area 210a of the first flexible layer 210. The portion of the second flexible layer 220 at least covering the sealing area 210a is a non-porous layer for sealing contact with external components.

As an example, as shown in FIG3 , in one embodiment, the second flexible layer 220 is disposed on a side of the first flexible layer 210 facing the liquid storage space 110, and the second flexible layer 220 covers the entire surface of the first flexible layer 210, that is, the second flexible layer 220 covers the pressure relief area 210b and the sealing area 210a of the first flexible layer 210, and the second flexible layer 220 is a non-porous layer as a whole, and the first holes 211 are evenly spaced and arranged on the sealing area 210a and the pressure relief area 210b of the first flexible layer 210. Since the surface of the first flexible layer 210 is covered with the second flexible layer 220, the second flexible layer 220 can be in sealing contact with external components, and the first hole 211 arranged in the sealing area 210a of the first flexible layer 210 will not affect the sealing between the opening of the liquid storage container 100 and the external components.

In other embodiments, the sealing area 210a of the first flexible layer 210 may be provided with the first hole 211 or may not be provided with the first hole 211, and the sealing between the opening of the liquid storage container 100 and the external components will not be affected. In addition, those skilled in the art can cover more of the first flexible wall 200 and the second flexible wall 200 at other positions of the liquid storage container 100 according to the actual situation of the product, such as the inner wall of the vent pipe 120 facing the liquid storage space 110.

Further, as shown in FIG4 , the second flexible layer 220 covers the first holes 211 of the first flexible layer 210 ;

In the pressure relief area 210b, the pore structure further includes a plurality of second holes 221 spaced apart on the second flexible layer 220, and at least some of the second holes 221 are connected to at least some of the first holes 211 in a one-to-one correspondence;

When the fluid in the liquid storage space 110 expands due to heat, it can enter the second hole 221 and the first hole 211 in the pressure relief area 210 b in sequence.

As an example, as shown in Figure 4, in one embodiment, the second flexible layer 220 is arranged on the side of the first flexible layer 210 facing the liquid storage space 110, the second flexible layer 220 covers the entire surface of the first flexible layer 210, the portion of the second flexible layer 220 covering the sealing area 210a of the first flexible layer 210 is a non-porous layer for sealing contact with external components, the first holes 211 are evenly spaced on the sealing area 210a and the pressure relief area 210b of the first flexible layer 210, the portion of the second flexible layer 220 covering the pressure relief area 210b of the first flexible layer 210 has a plurality of spaced second holes 221, the second holes 221 are connected to the first holes 211 in a one-to-one correspondence, the first holes 211 and the second holes 221 are connected to jointly provide a pressure relief space for the fluid in the liquid storage space 110, and the fluid in the liquid storage space 110 can enter the second holes 221 and the first holes 211 in sequence when the fluid in the liquid storage space 110 expands due to heat.

The inventor of the present application has found in practice that if the second flexible layer 220 without holes is fully covered on the side of the first flexible layer 210 facing the liquid storage space 110, although it can play a certain role in pressure relief, it is required that the distribution area of the first holes 211 occupies a large area on the inner wall of the container body, and the hole diameter is also large. In the embodiment of the present application, the fluid (mainly the liquid part) in the liquid storage space 110 can reduce thermal expansion by means of the heat insulation effect of the first flexible layer 210 and the second flexible layer 220 in the external high temperature environment. At the same time, by setting the second hole 221 on the second flexible layer 220, the fluid enters the first hole 211 through the second hole 221 during thermal expansion, which can ensure that the hole diameter of the first hole 211 can be made relatively large, so that the liquid in the liquid storage space 110 will not directly enter the first hole 211 at room temperature due to the large hole diameter of the first hole 211, thereby improving the overall pressure relief function of the flexible wall 200.

In this embodiment, the second hole 221 and the first hole 211 are through holes that penetrate the second flexible layer 220 and the first flexible layer 210 in the thickness direction, and the second hole 221 and the first hole 211 are both cylindrical. In other embodiments, the second hole 221 may also be a tapered hole, a stepped hole, or a hemispherical hole with a gradually decreasing aperture in the thickness direction.

In some embodiments, the second hole 221 is a capillary hole, and the pore size of the second hole 221 is smaller than the pore size of the first hole 211 .

As shown in Figure 4, the second hole 221 is a capillary pore, and the liquid fluid in the liquid storage space 110 can produce a capillary phenomenon in the capillary pore, which is mainly manifested in that at room temperature, the liquid fluid in the liquid storage space 110 does not infiltrate the second hole 221, and the liquid fluid in the liquid storage space 110 will not enter the second hole 221. The aperture of the second hole 221 is smaller than the aperture of the first hole 211. Regardless of whether the first hole 211 is set as a capillary pore or a non-capillary pore, the liquid fluid in the liquid storage space 110 will not enter the first hole 211 at room temperature, and will not affect the formation of a pressure relief space in the liquid storage container 100. In this embodiment, the first hole 211 is set as a capillary pore.

The aperture of the first hole 211 is larger than that of the second hole 221 , and a larger pressure relief space is provided for the fluid in the liquid storage space 110 .

In some embodiments, the aperture of the second hole 221 is 5%-30% of the aperture of the first hole 211. Specifically, the aperture of the second hole 221 may range from 0.01 mm to 0.8 mm.

As shown in FIG. 4 , in some embodiments, the first hole 211 and the second hole 221 are both capillary holes, and the aperture of the second hole 221 is set to 30% of the aperture of the first hole 211 .

In other embodiments, the second hole 221 is a capillary pore and the first hole 211 is a non-capillary pore, wherein the second hole 221 is 0.01 mm to 0.8 mm and the first hole 211 is 1 mm to 3 mm. At this time, the specific pore size of the second hole 221 can be selected within the above range as 5%-30% of the pore size of the first hole 211, or other percentages.

In some embodiments, the hardness of the second flexible layer 220 is less than the hardness of the first flexible layer 210 . Specifically, the hardness of the second flexible layer 220 is 10%-40% of the hardness of the first flexible layer 210 .

In some embodiments, the wall thickness of the second flexible layer 220 is less than the wall thickness of the first flexible layer 210 . Specifically, the thickness of the second flexible layer 220 is 25%-50% of the thickness of the first flexible layer 210 .

In other embodiments, the hardness of the second flexible layer 220 is less than that of the first flexible layer 210 , and the wall thickness of the second flexible layer 220 is less than that of the first flexible layer 210 .

With this arrangement, the first flexible layer 210 can also support the second flexible layer 220 . The second flexible layer 220 has stronger ductility and elasticity than the first flexible layer 210 , further expanding the pressure relief space generated by the elastic deformation of the flexible wall 200 in the liquid storage space 110 .

As an example, the first flexible layer 210 has a DuPont hardness of 25 to 45 degrees, and the second flexible layer 220 has a DuPont hardness of 5 to 20 degrees. At this time, within the above-mentioned specific hardness ranges of the first flexible layer 210 and the second flexible layer 220, a hardness value that satisfies the hardness of the second flexible layer 220 is 10% to 40% of the hardness of the first flexible layer 210 can be selected, or a value that is not within the above percentage range can be selected.

The DuPont hardness is used to characterize the hardness of an elastic material. The second flexible layer 220 is used to provide support for the first flexible layer 210. As shown in FIG3 , in one embodiment, when the ambient temperature rises, the fluid inside the liquid storage space 110 expands due to heat, and the pressure inside the liquid storage space 110 increases. When the first flexible layer 210 and the second flexible layer 220 are subjected to the same pressure, the elastic deformation of the second flexible layer 220 will be greater than that of the first flexible layer 210, and the second flexible layer 220 will be recessed toward the first hole 211 of the first flexible layer 210.

In some embodiments, the flexible wall 200 has a wall thickness of 1 mm to 6 mm.

As an example, as shown in FIGS. 1 and 2 , if only the first flexible layer 210 is integrally formed on the inner wall of the container body, the thickness of the first flexible layer 210 is 1 mm to 5 mm, and the total wall thickness of the flexible wall 200 is 1 mm to 5 mm.

As shown in FIGS. 3 and 4 , if the flexible wall 200 includes a first flexible layer 210 and a second flexible layer 220, the total wall thickness of the flexible wall 200 is 3 mm to 6 mm, wherein the thickness of the first flexible layer 210 may be 2 mm to 4 mm, and the thickness of the second flexible layer 220 may be 0.5 mm to 2 mm. For example, the thickness of the first flexible layer 210 is 2 mm, and the thickness of the second flexible layer 220 may be 1 mm, or the thickness of the first flexible layer 210 is 2.5 mm, and the thickness of the second flexible layer is 0.5 mm, 0.6 mm or 1 mm, etc. It should be noted that, in the case of satisfying the above-mentioned overall thickness, within the respective thickness ranges of the first flexible layer 210 and the second flexible layer 220, a specific value that satisfies that the thickness of the second flexible layer 220 is 25%-50% of the thickness of the first flexible layer 210 may be selected, or other values that are not within the above-mentioned percentage range may be selected.

Compared with the liquid storage container 100 with an external elastic pressure relief device, the thickness of the flexible wall 200 in the utility model is in the millimeter level, which can not only meet the pressure relief function of the fluid in the liquid storage space 110 due to thermal expansion, but also make the liquid storage container 100 thinner and more portable, ensuring that there is enough liquid storage space 110 inside the liquid storage container 100.

Furthermore, the material of the container body is thermoplastic plastic, and the material of the flexible wall 200 is thermoplastic elastomer.

Thermoplastic elastomers are also called thermoplastic rubbers. Thermoplastic elastomers can exhibit rubber elasticity at room temperature and can be plasticized and formed at high temperatures. In this embodiment, the material of the flexible wall 200 is silicone, and the first flexible layer 210 and the second flexible layer 220 use the same material with different hardness. In other embodiments, the first flexible layer 210 and the second flexible layer 220 can also be made of different thermoplastic elastomer materials with good bonding properties.

The atomizer assembly 300 is an external component in the above embodiment of the liquid storage container 100.

Further, referring to FIGS. 1 to 7 , the liquid storage container 100 has an air passage 130 , and the atomizing assembly 300 includes a liquid inlet passage 312 , an air inlet passage 323 , and a heating assembly; the heating assembly includes an oil guide body 340 and a heating body 330 ;
