All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises the element.

Referring to fig. 1 and 2, a cleaning apparatus 100 according to an embodiment of the present application includes a base station 10 and a hand-held cleaning tool 20 (e.g., a hand-held cleaner). The base station 10 is configured to house the hand-held cleaning tool 20, for example, for the hand-held cleaning tool 20 to be placed on standby or for charging the hand-held cleaning tool 20 at the same time. The base station 10 includes a cavity 11, a receiving slot 12 and a dust guard assembly 13. The filter screen 131 of the dust-proof assembly 13 is disposed between the cavity 11 and the receiving groove 12, so that the cavity 11 and the receiving groove 12 communicate with each other through the filter screen. Further, a fan 14 is provided in the chamber 11 to generate an air flow in the chamber 11, the air flow having a flow path through the screen 131 into the receiving groove 12. In certain embodiments of the present application, the blower 14 may be, but is not limited to, activated when the hand-held cleaning tool 20 is received in the receiving slot 12, and deactivated after the hand-held cleaning tool 20 exits the receiving slot 12. In other embodiments of the present application, the fan 14 may be turned on or off by the user's own choice through a corresponding switch on the base station 10.

The air inlet end of the hand-held cleaning tool 20 is provided with a dust suction opening 221, and when the hand-held cleaning tool 20 is accommodated in the accommodating groove 12, the dust suction opening 221 corresponds to the filter screen 131, and may be, but is not limited to, inclined downward or downward to be suspended above the filter screen 131 or contact or abut against the filter screen 131. Therefore, when the blower 14 is started, the air flow generated by the blower 14 can flow into the dust collection opening 221 through the filter screen 131 toward the receiving slot 12. In this way, the dust or particles remaining in the dust collection opening 221 or falling out of the dust collection barrel of the hand-held cleaning tool 20 can be carried into the dust collection barrel under the interception of the filter screen 131 and the driving of the air flow, so as to effectively avoid secondary pollution caused by the particles or dust in the hand-held cleaning tool 20 falling into the storage tank.

As shown in fig. 2 to 7, in some embodiments of the present application, a through hole 15 communicating between the cavity 11 of the base station 10 and the receiving groove 12 is provided, and the dust prevention assembly 13 includes a reset member 132 connected to the filter screen 131 in addition to the filter screen 131. The filter 131 is disposed in the through hole 15, one end of the reset element 132 is disposed in the cavity 11, and the other end is connected to the filter 131, and supports the filter 131 at the initial position P1 to be exposed on the inner surface of the receiving groove 12. The restoring member 132 may be, but not limited to, a spring or a shrapnel, and its structure can maintain the filter screen 131 at the initial position P1 under the condition of no external force (e.g. external force applied to the filter screen 131), or drive the filter screen 131 to move to the avoiding position P2 and sink into the through hole 15 when being pressed by external force (e.g. external force applied to the filter screen 131). It can be understood that, when the external force pressing the filter 131 is eliminated, the reset element 132 can drive the filter 131 to return to the initial position P1 by the elastic force thereof.

Therefore, when the hand-held cleaning tool 20 is accommodated in the accommodating groove 12, the dust suction opening 221 contacts with the filter screen 131 of the dust-proof assembly 13, and pushes the filter screen 131 to compress the reset member 132 toward the cavity 11, so that the filter screen 131 is displaced to the avoiding position P2. At this time, the filter screen 131 is blocked on the dust suction port 221, and dust and particles larger than the fine pore size are blocked in the dust suction port 221 according to the fine pore size on the filter screen 131. It should be noted that when the dust or particles fall onto the filter screen 131, the dust or particles are sucked into the dust collecting barrel of the hand-held cleaning tool 20 again through the dust collecting opening 221 by the air flow.

When the hand-held cleaning tool 20 leaves the receiving groove 12, the external force applied to the filter screen 131 is eliminated, so that the filter screen 131 of the dust-proof assembly 13 can be pushed by the elastic force of the reset member 132 to displace toward the receiving groove 12, thereby returning to the initial position P1 and blocking between the receiving groove 12 and the cavity 11, so as to prevent foreign objects or dust from entering the cavity 11.

As shown in fig. 3-5, in some embodiments of the present application, screen 131 further includes a support frame 1311 and a screen body 1312. The sidewall of the support frame 1311 surrounds the outer circumference of the filter screen 131, and a socket 1313 is further provided in the support frame 1311. Socket 1313 may be, but is not limited to, a tubular structure (e.g., tubular) and extends toward reset element 132. The reset element 132 includes a first end 1321 and a second end 1322 opposite to each other, the first end 1321 is disposed in the cavity 11, and the second end 1322 is disposed in the socket 1313 and contacts the net body 1312, so as to be pushed against the filter screen 131 to support the filter screen 131 at the initial position P1, or pushed against by the filter screen 131 to retract toward the first end 1321.

In addition, in some embodiments of the present application, the base station 10 further includes a housing 101 and a fixing base 102. The casing 101 is provided with an opening 103, and the fixing seat 102 is arranged on the casing 101 and seals the opening 103, so that a closed cavity 11 is formed between the fixing seat 102 and the casing 101. For example: the opening 103 is disposed at the bottom of the housing 101, which facilitates assembly or maintenance of internal parts, and the opening 103 is closed by the fixing seat 102 after the operation is completed.

The cavity 11 further includes a positioning post 111, where the positioning post 111 may be, but is not limited to, disposed on the fixing seat 102 or on a wall surface at a proper position in the housing, and extends toward the direction of the receiving slot 12 to correspond to the through hole 15. The top of the positioning column 111 is provided with a groove 1111, and a first end 1321 of the reset element 132 is disposed in the groove 1111. In this way, during assembly, only the opposite ends of the reset element 132 are respectively inserted into the socket 1313 and the groove 1111, so as to position the reset element 132 to avoid sliding or shifting.

In addition, in order to keep the filter screen 131 stable during displacement, in some embodiments of the present application, the guide rail 112 is further disposed in the cavity 11, and the corresponding limiting portion 1314 is disposed on the outer peripheral surface of the supporting frame 1311. Wherein, the guide rail 112 is disposed along an end edge of the through hole 15, and the limiting portion 1314 and the guide rail 112 may be, but not limited to, matched concave-convex structures, for example: the guide rail 112 is a slot, the limiting portion 1314 is a bump with a matched structure, or the guide rail 112 is a rib, and the limiting portion 1314 is a groove with a matched structure, so that the limiting portion 1314 is slidably disposed on the guide rail 112. In the embodiment of the present application, the number of the guide rails 112 is three, and the number of the corresponding limiting portions 1314 is also three as an example, but the embodiment of the present application is not limited thereto, and the number thereof may be determined according to the actual requirement.

Furthermore, in other embodiments of the present application, the guide rail 112 may also include a closed end 1121 proximate the through-hole 15 and an open end 1122 distal from the through-hole 15. In the present embodiment, the open end 1122 is located at a position opposite to the closed end 1121 for the limiting portion 1314 to enter the guide rail 112, and the closed end 1121 is used for blocking the limiting portion 1314 from continuously moving toward the through hole 15 when the filter screen 131 is pushed upward by the reset member 132, so as to limit the moving range of the filter screen 131. In this way, when the filter screen 131 is not pressed by an external force, the elastic force of the reset element 132 pushes the filter screen 131 to displace toward the receiving slot 12, and after the limiting portion 1314 contacts the closed end 1121, the filter screen 131 is limited at the initial position P1, so as to avoid the filter screen 131 from being separated from the base station 10.

It should be noted that in some embodiments, the handheld cleaning tool 20 further includes a dust collecting barrel 21 and an air inlet 22 provided with a dust collecting opening 221, and the receiving slot 12 includes a first receiving area 121 and a second receiving area 122. The outer appearance structures of the first receiving area 121 and the second receiving area 122 respectively conform to the outer appearance structures of the dust collection tube 21 and the air inlet end 22 to have different outer appearances. The first accommodating area 121 and the second accommodating area 122 have a step therebetween, and when the hand-held cleaning tool 20 is accommodated in the accommodating groove 12, the dust collecting barrel 21 and the air inlet end 22 can be combined therein respectively. In the present embodiment, the through hole 15 is disposed between the second receiving area 122 and the cavity 11. Thus, the method is applicable to a variety of applications. When the hand-held cleaning tool 20 is accommodated in the accommodating groove 12, the air inlet 22 is located in the second accommodating area 122, such that the dust suction opening 221 passes through the through hole 15 toward the cavity 11 and correspondingly pushes against the filter screen 131.

As shown in fig. 6 and 8, in some embodiments of the present application, one side of the base station 10 may also be provided with an air intake hole 1011. For example: a plurality of air intake holes 1011 penetrating the wall surface of the housing are provided at one side of the housing 101 so that the cavity 11 can communicate with the external environment through the air intake holes 1011. When the fan 14 is in an operating state, external air can be guided to enter the cavity 11 through the air inlet 1011, and an air flow flowing toward the filter screen 131 is formed in the cavity 11. It should be noted that the base station 10 may further be provided therein with a dust collecting device, and is in communication with the dust collecting cylinder 21 and the air inlet 22 when the hand-held cleaning tool 20 is accommodated in the accommodating groove 12. For example: the dust collection cylinder 21 of the hand-held cleaning tool 20 may be provided with a cover which is opened manually or automatically by a corresponding mechanism on the base station 10 when the hand-held cleaning tool 20 is received in the receiving groove 12, so that the dust collection cylinder 21 and the air inlet end 22 can communicate with the dust collection apparatus. In this way, the dust or particles in the dust collection tube 21 and the dust collection opening 221 are driven into the dust collection device (as indicated by the dotted arrow in fig. 7) by the airflow, so that the dust in the dust collection tube 21 is emptied, and the dust or particles in the dust collection opening 221 are prevented from falling into the cavity 11.

In other embodiments of the present application, the cleaning apparatus 100 may also include a self-moving robot 70, and the base station 10 may also have the capability to dock and house the hand-held cleaning tool 20 from the moving robot 70. The base station 10 further includes a cabin 16, and the cabin 16 is isolated from the cavity 11 and the receiving slot 12, so that the self-moving robot 70 can be parked in the cabin 16 (as shown in fig. 1), and the hand-held cleaning tool 20 is received in the receiving slot 12 at the other side of the cabin 16. In this way, the dust collecting device of the base station 10 not only realizes the shared design, but also solves the problem that the existing hand-held dust collector can only be cleaned manually.

The following describes the technical solution in the embodiment of the present application in detail in connection with a specific application scenario.

And (3) applying the first scene. When the holding groove 12 does not hold the hand-held cleaning tool 20, the reset member 132 pushes the filter 131 to the initial position P1, so that the filter 131 is blocked between the holding groove 12 and the cavity 11, so as to prevent foreign objects or dust from entering the base station 10.

And (3) applying a second scene. When the hand-held cleaning tool 20 is accommodated in the accommodating groove 12, the dust collection opening 221 pushes the filter screen 131, so that the filter screen 131 moves from the starting position P1 to the avoiding position P2 and is blocked on the dust collection opening 221, so as to prevent dust or particles in the dust collection opening 221 from entering the base station 10. At this time, the blower 14 is started to generate an air flow in the cavity 11, so that the dust or particles remained or dropped into the dust collection opening 221 are carried to the dust collection barrel 21 or the dust collection device to be collected under the driving of the air flow.

And (3) application scene III. The base station 10 includes a cabin 16 and a receiving slot 12, so that the self-moving robot 70 can be parked in the cabin 16, and the hand-held cleaning tool 20 is received in the receiving slot 12, which has the advantages and effects of sharing dust collecting equipment and automatic dust collection.

It can be seen from the above description that, according to the embodiment of the application, through the elastic displacement design of the filter screen, when the handheld cleaning tool is accommodated in the accommodating groove, the filter screen is located at the avoiding position and is blocked at the dust collection opening, so that dust or particles at the dust collection opening can be prevented from falling into the cavity, and when the handheld cleaning tool leaves the accommodating groove, the filter screen is located at the starting position and is blocked between the accommodating groove and the cavity, so that external objects or dust can be prevented from entering the base station. In addition, the dust in the dust collection cylinder can be emptied through the air flow generated by the fan, and meanwhile, the dust or particles falling to the filter screen can be sucked into the dust collection port again and driven into the dust collection equipment.

The foregoing is merely exemplary of the present application and is not intended to limit the present application. Various modifications and changes may be made to the present application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. which are within the spirit and principles of the present application are intended to be included within the scope of the claims of the present application.
