[0038] The cleaning equipment with the water tank has a wet mopping function, which can meet the cleaning needs of users. In the related art, the water tank water outlet control scheme is mostly a manual switch or an electrically controlled switch for the water outlet. The manual switch needs to be manually operated by the user to open or close, and there is a risk of forgetting to close the water tank, causing the water tank to continuously discharge water. The control scheme of the electrically controlled switch is complex and high in cost, and there is also a risk of water leakage. If the accumulated water leaked from the water tank is not cleaned in time, it will cause damage to the ground, dampness, and mold breeding, etc., reducing the user's experience of using the cleaning equipment.

[0039] The present disclosure provides a switch assembly applied to a water tank. Figure 1This is a three-dimensional structural diagram of a blocking switch of a switching assembly in the open position according to an exemplary embodiment of the present disclosure. Figure 2 This is a cross-sectional view of a blocking switch of a switching assembly in the open position, according to an exemplary embodiment of this disclosure. Figure 3 This is a three-dimensional structural diagram of a blocking switch of a switching assembly in the closed position according to an exemplary embodiment of the present disclosure. Figure 4 This is a schematic cross-sectional view of a blocking switch of a switching assembly in the closed position, according to an exemplary embodiment of this disclosure. Figures 1-4 As shown, the switch assembly 1 includes a housing 11, a blocking switch 12, and a sealing assembly 13. The housing 11 has a first cavity 111, and the cavity wall surrounding the first cavity 111 has a first vent 1111 and a second vent 1112. The first vent 1111 communicates with the outside of the water tank 2, and the second vent 1112 communicates with the inside of the water tank 2. The blocking switch 12 is movably assembled to the housing 11. The blocking switch 12 includes a blocking part 122 disposed within the first cavity 111. The blocking part 122 blocks or moves away from the second vent 1112 as the blocking switch 12 moves. The sealing assembly 13 includes a flexible sealing element 131, a counterweight 133, and a deformable connector 132 connecting the flexible sealing element 131 and the counterweight 133. The flexible sealing element 131 blocks the first vent 1111, and the flexible sealing element 131 has a slit 1311. The slit 1311 is in a closed state when the counterweight 133 is stationary, and in an open state when the counterweight 133 is moving.

[0040] Because the housing 11 of the aforementioned switch assembly 1 has a first cavity 111, and the cavity wall surrounding the first cavity 111 has a first vent 1111 and a second vent 1112, the second vent 1112 can be opened or closed by controlling the sealing switch 12, and the first vent 1111 can be opened or closed with the movement or stillness of the counterweight 133. When the internal and external air passages are connected, the water tank 2 can complete the drainage operation from the outlet. The sealing switch 12 and the sealing assembly 13 provide dual control to achieve the opening and closing of the air passages inside and outside the water tank 2. The sealing assembly 13 only opens the slit 1311 due to the inertia of the counterweight 133 during movement, preventing water leakage from the water tank 2 if the sealing switch 12 or the water tank 2 outlet switch is forgotten to be closed or the sealing fails. This disclosure ensures the sealing effect of the water tank 2 in the non-draining state through a simple structural design, improving the user experience of the water tank 2 and the cleaning equipment using the aforementioned water tank 2.

[0041] In some embodiments, the shell 11 further comprises a second cavity 112 in communication with the inside of the water tank 2, and the first cavity 111 and the second cavity 112 are in communication through a second air vent 1112. The second cavity 112 can serve as a buffer space between the water storage space of the water tank 2 and the first cavity 111, avoiding the problem of water flowing into the first cavity 111 when the air passage of the water tank 2 is in communication, and improving the use reliability of the switch assembly 1.

[0042] In the above embodiments, the cavity wall of the second cavity 112 can comprise a second side wall provided with a third air vent 1121 in communication with the inside of the water tank 2. The communication between the second cavity 112 and the water tank 2 is realized through the third air vent 1121, so that the structure of the second side wall can form a barrier with the water storage space of the water tank 2, reducing the possibility of water flowing into the second cavity 112 of the water tank 2.

[0043] In some embodiments, the switch assembly 1 can be assembled on the bottom plate inside the water tank 2, and the cavity wall surrounding the first cavity 111 comprises a first bottom wall fitted to the bottom plate and a first side wall connected to the bottom wall, and the first air vent 1111 is arranged on the first bottom wall, and the second air vent 1112 is arranged on the first side wall. The first air vent 1111 is arranged on the first bottom wall to facilitate communication with the fourth air vent on the bottom of the water tank 2, and the fourth air vent on the bottom of the water tank 2 avoids the problem of the air inlet passage being covered and blocked by free-falling dust or particulate matter when the water tank 2 is in normal use and idle. The second air vent 1112 is arranged on the first side wall, so that the blocking part 122 can block or move away from the second air vent 1112 during transverse movement, which helps to optimize the movement trajectory and structure of the blocking part 122.

[0044] For example, a first barrier structure 14 arranged in the longitudinal direction, a third barrier structure 16 arranged in the longitudinal direction, and a second barrier structure 15 arranged in the transverse direction can be arranged inside the shell 11, and the first cavity 111 is surrounded by the outer wall of the shell 11, the bottom plate of the shell 11, the first barrier structure 14 and the second barrier structure 15. The bottom plate of the shell 11, the third barrier structure 16, the first barrier structure 14 and the second barrier structure 15 surround the second cavity 112. Among them, the bottom plate of the shell 11 can serve as the above-mentioned first bottom wall provided with the first air vent 1111, and the first barrier structure 14 can serve as part of the first side wall provided with the second air vent 1112.

[0045] In some embodiments, as Figure 5As shown, the shell 11 can further include a sliding groove 113, the sealing switch 12 includes an operation part 121 arranged outside the first cavity 111, and the bottom of the sliding groove 113 is provided with an assembly opening 1132 communicating with the first cavity 111. The operation part 121 is movably assembled in the sliding groove 113 and connected with the sealing part 122 through the assembly opening 1132. The sealing part 122 can be moved by sliding the operation part 121 along the sliding groove 113, and thus the sealing part 122 can seal or move away from the second air vent 1112.

[0046] In the above embodiment, the operation part 121 covers the assembly opening 1132 at any position. That is, the operation part 121 can still cover and seal the assembly opening 1132 during movement, avoiding air leakage at the assembly opening 1132 and causing the water tank 2 to leak.

[0047] In some embodiments, as shown in Figure 3 , Figure 4 The groove wall of the sliding groove 113 can be provided with a limiting structure 1131, and the limiting structure 1131 includes a transverse limiting part. In the sliding direction of the operation part 121, the operation part 121 is limitedly matched with the transverse limiting part at least at the limit position, so as to form the limiting of the operation part 121 at the opening position and the closing position. The transverse limiting part can be two limiting ribs arranged in the longitudinal direction on the groove wall. When the operation part 121 abuts against the limiting ribs arranged in the longitudinal direction, the opening position or the closing position can be limited.

[0048] In the above embodiment, the limiting structure 1131 can further include a longitudinal limiting part, and the operation part 121 is limitedly matched with the longitudinal limiting part in the depth direction of the sliding groove 113. The longitudinal limiting part can be a limiting rib arranged in the transverse direction on the groove wall. When the operation part 121 is matched with the limiting rib arranged in the transverse direction, the limiting in the depth direction of the sliding groove 113 can be formed.

[0049] For example, the transverse limiting part and the longitudinal limiting part form two limiting grooves arranged on the groove wall. When the operation part 121 is matched with one side limiting groove, the opening position is located, and the sealing part 122 is separated from the second air vent 1112. When the operation part 121 is matched with the other side limiting groove, the sealing part 122 seals the second air vent 1112. When the operation part 121 is matched with the above limiting groove, the operation part 121 can also avoid the longitudinal movement, and the use reliability of the operation part 121 is improved.

[0050] In the above embodiment, the cavity wall of the first cavity 111 includes a top wall forming a groove bottom of the sliding groove 113, and one of the operation part 121 and the groove bottom includes an elastic material. The elastic material can improve the sealing performance of the operation part 121 and the groove bottom, thereby preventing air leakage at the assembly port 1132. The elastic material can be hard or soft silicone, for example. The operation part 121 can be made of ABS plastic, and the groove bottom can be made of silicone.

[0051] In the above embodiment, the operation part 121 can include a sliding block 1211 and a decorative piece 1212 covering the sliding block 1211. The sliding block 1211 is in sliding cooperation with the sliding groove 113, and a user can hold the decorative piece 1212 to apply force to push the operation part 121 to slide.

[0052] In some embodiments, the switch assembly 1 can include an electric control module. The blocking switch 12 is connected to a driving end of the electric control module to drive the blocking part 122 to block or move away from the second air vent 1112. When the blocking switch 12 is driven by the electric control module, the second air vent 1112 can be automatically controlled to open and close, thereby improving the intelligent control performance.

[0053] In some embodiments, the blocking part 122 can include a connecting structure 1221 and an elastic sealing structure 1222 arranged at one end of the connecting structure 1221. The connecting structure 1221 can be connected to the driving end of the electric control module or the manually controlled operation part 121. The elastic sealing structure 1222 can be an elastic structure made of rubber, silicone, or the like arranged at one end of the connecting structure 1221.

[0054] In the above embodiment, the second air vent 1112 has one of a circular shape, a conical shape, and a square shape. The elastic sealing structure 1222 matches the shape of the second air vent 1112, and the present disclosure does not limit the material.

[0055] In some embodiments, the soft sealing piece 131, the deformation connecting piece 132, and the counterweight 133 form an integrated structure to improve the structural reliability and processing convenience of the sealing assembly 13. The materials of the soft sealing piece 131, the deformation connecting piece 132, and the counterweight 133 can be rubber, silicone, or the like, and the present disclosure does not limit the materials.

[0056] The deformation connecting piece 132 can have a rod-shaped structure to support the counterweight 133. When the switch assembly 1 moves with the device, the counterweight 133 deforms the deformation connecting piece 132 due to gravity and pulls the soft sealing piece 131 to open the gap 1311. When the device is stationary, the deformation connecting piece 132 supports the counterweight 133 and does not pull the soft sealing piece 131, so the gap 1311 is in a closed state.

[0057] In the above embodiment, the slit 1311 divides the flexible sealing member 131 into a first part and a second part, and the deformable connector 132 is disposed in either the first part or the second part. The deformable connector 132 is disposed in either the first part or the second part to facilitate pulling one side of the slit 1311, thus facilitating the opening of the slit 1311. The slit 1311 can be located in the middle of the flexible sealing member 131 to make the first part or the second part symmetrical. Alternatively, the slit 1311 can be located in other positions on the flexible sealing member 131 to make the first part or the second part have different dimensions.

[0058] In some embodiments, the slit 1311 described above includes a straight structure and / or a curved structure.

[0059] In some embodiments, such as Figures 6-8 As shown, the counterweight 133 can be one of a cuboid, sphere, prism, or polyhedron.

[0060] This disclosure further provides a cleaning device, which includes a water tank 2 and the aforementioned switch assembly 1, the switch assembly 1 being assembled in the water tank 2.

[0061] It should be noted that the aforementioned cleaning equipment can be a robotic vacuum cleaner, a window cleaning robot, a handheld sweeper, etc., and this disclosure does not limit this. Since the aforementioned switch assembly 1 is assembled into a module, it is easy to install onto the water tank 2 of different cleaning equipment.

[0062] The housing 11 of the aforementioned switch assembly 1 has a first cavity 111. The cavity wall surrounding the first cavity 111 has a first vent 1111 and a second vent 1112. The second vent 1112 can be opened or closed by controlling the sealing switch 12. The first vent 1111 can be opened or closed as the counterweight 133 moves or remains stationary. When the internal and external air passages are connected, the water tank 2 can complete the drainage operation from the outlet. The sealing switch 12 and the sealing assembly 13 provide dual control to achieve the opening and closing of the air passages inside and outside the water tank 2. The sealing assembly 13 only opens the slit 1311 due to the inertia of the counterweight 133 during movement, preventing the water tank 2 from leaking if the sealing switch 12 or the water tank 2 outlet switch is not closed or the sealing fails. This disclosure ensures the sealing effect of the water tank 2 in the non-draining state through a simple structural design, improving the user experience of the water tank 2 and the cleaning equipment using the aforementioned water tank 2.

[0063] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
