[0047] The cleaning equipment equipped with a water tank has a wet mopping function, which can meet the cleaning needs of users. In the related art, the water tank also has the user pain point that it is inconvenient to fill and pour water and cannot be poured cleanly. In addition, the water outlet control scheme of the water tank is mostly a manual switch or an electric control switch for the water outlet. The manual switch requires the user to manually operate it to open or close it, and there is a risk of forgetting to turn off the water tank and causing the water tank to continue to discharge water. The control scheme of the electric control switch is complex and costly, and there is also a risk of water leakage. If the accumulated water leaked from the water tank is not cleaned up in time, it is easy to cause damage to the ground, moisture and mold growth, etc., reducing the user's experience of using the cleaning equipment.

[0048] The present disclosure proposes a cleaning water tank and a cleaning device to solve at least some of the problems in the related art. The cleaning water tank and the cleaning device of the present disclosure are described in detail below in conjunction with the accompanying drawings. The features of the following embodiments and implementations can be combined with each other without conflict.

The water inlet 32 ​​and the water outlet are both connected to the water storage cavity 31. Figure 5 As shown, it can be understood that the water inlet 32 ​​can realize the function of filling / pouring water, and the number of the water inlet 32 ​​can be set according to actual needs, and the present disclosure does not limit this. The water outlet is used to discharge the water in the water storage chamber 31.

[0051] The switch assembly 10 is movably disposed on the water tank housing 30. When the switch assembly 10 is moved to the closed position, the water storage chamber 31 is isolated from the outside air, and the water in the water storage chamber 31 is blocked from flowing out from the water outlet. When the switch assembly 10 is moved to the open position, the water storage chamber 31 is connected to the outside air and a pressure difference is formed, and the water in the water storage chamber 31 is discharged from the water tank housing 30 from the water outlet under the action of the pressure difference. In practical applications, auxiliary tools such as a mop 90 can be assembled at the bottom of the water tank housing 30, and the water flowing out of the water outlet of the water tank housing 30 can wet auxiliary tools such as the mop 90 to realize the cleaning function. Optionally, auxiliary tools such as the mop 90 can be connected to the bottom of the water tank housing 30 through a connector 91 such as an adhesive plate, a Velcro, or a Velcro.

[0052] It can be seen from the above embodiments that the clean water tank 100 of the present disclosure can be filled with water and poured out by setting a water injection port 32 on the side of the water tank housing 30, solving the user pain point that the water injection port is only set directly above the water tank in the related art, which makes it inconvenient and not clean when filling and pouring water from the water tank. It has stronger environmental adaptability and provides users with more choices, solving the problem of poor user experience and improving user experience. By setting a switch assembly 10, the user pain point of the clean water tank 100 in the related art when it is forgotten to be turned off or when it is stationary, the water tank leaks, avoiding the risk of damage to the ground, moisture and mold, etc.

[0062] In some optional embodiments, the clean water tank 100 may further include a plug cover 50, which is movably arranged at the water inlet 32. In this way, when it is not necessary to fill / pour water, the plug cover 50 can seal the water inlet 32 ​​to prevent water in the water tank housing 30 from leaking out. When it is necessary to fill / pour water, the plug cover 50 can be temporarily removed from the water inlet 32 ​​to expose the water inlet 32. Optionally, the plug cover 50 is a soft rubber plug, which is sealed and connected to the water tank housing 30, and the soft rubber plug can achieve a better sealing effect. In order to achieve a better sealing effect, a sealing ring 51 can also be provided between the plug cover 50 and the water tank housing 30. It should be noted that the sealing form between the plug cover and the water tank housing can be achieved by a soft rubber and hard shell sealing method or a sealing ring and hard shell sealing method.

[0063] Furthermore, a first groove portion 36 may be respectively provided on the upper surface and the side surface of the water tank housing 30, the water injection port 32 is provided on the bottom wall of the first groove portion 36, and the plug cover 50 is movably provided in the first groove portion 36 corresponding to the water injection port 32.

[0066] In some optional embodiments, the water tank housing 30 may be provided with a first vent 1111, and the first vent 1111 is in communication with the inside of the water storage chamber 31 and the outside of the water storage chamber 31. When the switch assembly 10 is in the closed position, the switch assembly 10 blocks the first vent 1111 to isolate the water storage chamber 31 from the outside air. When the switch assembly 10 is in the open position, the switch assembly 10 exposes the first vent 1111 to connect the water storage chamber 31 with the outside air and form a pressure difference. In this way, water outflow control of the water tank is achieved.

[0067] See also Figures 7 to 10As shown, in some optional embodiments, the switch assembly 10 includes a housing 11, a blocking switch 12 and a sealing assembly 13. The housing 11 is disposed inside the water storage chamber 31 of the water tank housing 30. The housing 11 is provided with a first cavity 111, and the cavity wall surrounding the first cavity 111 is provided with a first vent 1111 and a second vent 1112, the first vent 1111 is connected to the outside of the water storage chamber 31, and the second vent 1112 is connected to the inside of the water storage chamber 31. The blocking switch 12 is movably assembled in the housing 11, and the blocking switch 12 includes a blocking portion 122 (which can be understood as a pin structure) disposed in the first cavity 111, and the blocking portion 122 blocks or moves away from the second vent 1112 as the blocking switch 12 moves. The sealing assembly 13 includes a soft sealing member 131, a counterweight member 133, and a deformable connecting member 132 connecting the soft sealing member 131 and the counterweight member 133. The soft sealing member 131 blocks the first vent 1111, and the soft sealing member 131 is provided with a slit 1311. The slit 1311 is in a closed state when the counterweight member 133 is stationary, and is in an open state when the counterweight member 133 moves.

[0068] Since the housing 11 of the switch assembly 10 is provided with a first cavity 111, the cavity wall surrounding the first cavity 111 is provided with a first vent 1111 and a second vent 1112, the second vent 1112 can be opened or closed by controlling the blocking switch 12, and the first vent 1111 can be opened or closed with the movement or stillness of the counterweight 133. The water storage chamber 31 can complete the drainage operation from the water outlet when the internal and external airways are connected, and the blocking switch 12 and the sealing assembly 13 are dually controlled to realize the opening and closing of the airways inside and outside the water storage chamber 31. The sealing assembly 13 will only open the slit 1311 due to the inertia of the counterweight 133 during the movement process, thereby avoiding the leakage of the water storage chamber 31 when the blocking switch 12 or the water storage chamber outlet switch is forgotten to be closed or the blocking fails. The present disclosure ensures the sealing effect of the water storage chamber 31 in a non-draining state through a simple structural setting, and improves the user experience of the water storage chamber 31 and the cleaning equipment using the above-mentioned water storage chamber 31.

[0069] In some embodiments, the housing 11 further includes a second cavity 112 in communication with the interior of the water storage chamber 31, and the first cavity 111 and the second cavity 112 are in communication with each other through a second vent 1112. The second cavity 112 can be used as a buffer space between the water storage space of the water storage chamber 31 and the first cavity 111, thereby avoiding the problem of water flowing into the first cavity 111 when the air passages inside and outside the water storage chamber 31 are in communication, and improving the reliability of the switch assembly 10.

[0070] In the above embodiment, the cavity wall of the second cavity 112 may include a second side wall, and the second side wall is provided with a third vent 1121 communicating with the inside of the water storage cavity 31. The second cavity 112 is communicated with the water storage cavity 31 through the third vent 1121, so that the structure of the second side wall can form a barrier with the water storage space of the water storage cavity 31, thereby reducing the possibility of water in the water storage cavity 31 flowing into the second cavity 112.

[0071] In some embodiments, the switch assembly 10 can be assembled on the bottom plate inside the water storage chamber 31, and the cavity wall surrounding the first cavity 111 includes a first bottom wall matched with the bottom plate and a first side wall connected to the bottom wall, and the first vent 1111 is set on the first bottom wall, and the second vent 1112 is set on the first side wall. The first vent 1111 is set on the first bottom wall to facilitate the coordination and communication with the fourth vent at the bottom of the water storage chamber 31. The fourth vent at the bottom of the water storage chamber 31 avoids the problem of the air inlet channel being covered and blocked by free-falling dust or particles when the water storage chamber 31 is in normal use or idle and laid flat. The second vent 1112 is set on the first side wall, so that the blocking portion 122 can block or stay away from the second vent 1112 during the lateral movement, which helps to optimize the movement trajectory and structural setting of the blocking portion 122.

[0072] For example, a first baffle structure 14, a third baffle structure 16, and a second baffle structure 15 arranged in the longitudinal direction and in the transverse direction may be arranged inside the shell 11, and the outer wall of the shell 11, the bottom plate of the shell 11, the first baffle structure 14, and the second baffle structure 15 may enclose a first cavity 111. The bottom plate of the shell 11, the third baffle structure 16, the first baffle structure 14, and the second baffle structure 15 may enclose a second cavity 112. The bottom plate of the shell 11 may serve as the first bottom wall provided with the first vent 1111, and the first baffle structure 14 may serve as part of the first side wall provided with the second vent 1112.

[0073] In some embodiments, Fig.11 As shown, the housing 11 may further include a slide slot 113, and the blocking switch 12 includes an operating portion 121 disposed outside the first cavity 111. The bottom of the slide slot 113 is provided with an assembly port 1132 communicating with the first cavity 111. The operating portion 121 is movably assembled in the slide slot 113, and is connected to the blocking portion 122 through the assembly port 1132. The blocking portion 122 can be driven to move by manually controlling the operating portion 121 to slide along the slide slot 113, so that the blocking portion 122 can block or move away from the second vent 1112.

[0074] In the above embodiment, the operating part 121 covers the assembly opening 1132 at any position. That is, the operating part 121 can still cover and block the assembly opening 1132 during the movement, so as to avoid air leakage at the assembly opening 1132 and water leakage of the water storage chamber 31.

[0075] In some embodiments, Fig. 9 , Fig.10 As shown, the groove wall of the sliding groove 113 may be provided with a limiting structure 1131, and the limiting structure 1131 includes a transverse limiting portion. In the sliding direction of the operating portion 121, the operating portion 121 is limited and matched with the transverse limiting portion at least at the extreme position to form a limit for the operating portion 121 in the open position and the closed position. The transverse limiting portion can be two limiting ribs arranged in the longitudinal direction on the groove wall. When the operating portion 121 abuts against the limiting ribs arranged in the longitudinal direction, the limit of the open position or the closed position can be formed.

[0076] In the above embodiment, the limiting structure 1131 may further include a longitudinal limiting portion, and the operating portion 121 is engaged with the longitudinal limiting portion for limiting in the depth direction of the slide groove 113. The longitudinal limiting portion may be a limiting rib disposed on the groove wall in the transverse direction, and when the operating portion 121 cooperates with the limiting rib disposed in the transverse direction, limiting in the depth direction of the slide groove 113 can be formed.

[0077] For example, the transverse limiting portion and the longitudinal limiting portion form two limiting grooves arranged on the groove wall. When the operating portion 121 is engaged with the limiting groove on one side, it is in the open position, and the blocking portion 122 is separated from the second vent 1112. When the operating portion 121 is engaged with the limiting groove on the other side, the blocking portion 122 blocks the second vent 1112. When the operating portion 121 is engaged with the limiting groove on the other side, the longitudinal movement of the operating portion 121 can be avoided, thereby improving the reliability of the operating portion 121.

[0078] In the above embodiment, the cavity wall of the first cavity 111 includes a top wall, which forms the bottom of the chute 113, and one of the operating portion 121 and the bottom of the chute includes an elastic material. The elastic material can improve the sealing performance of the operating portion 121 and the bottom of the chute, and avoid air leakage at the assembly port 1132. The elastic material can be hard or soft silicone. For example, the operating portion 121 can be ABS plastic, and the bottom of the chute is made of silicone.

[0079] In the above embodiment, the operating part 121 may include a slider 1211 and a decorative piece 1212 covering the slider 1211 . The slider 1211 slidably cooperates with the slide groove 113 . The user may hold the decorative piece 1212 and apply force to push the operating part 121 to slide.

[0080] In some embodiments, the switch assembly 10 may include an electric control module, and the blocking switch 12 is connected to the driving end of the electric control module to controllably drive the blocking portion 122 to block or move away from the second vent 1112. When the blocking switch 12 is driven by the electric control module, automatic control of the opening and closing of the second vent 1112 can be achieved, thereby improving control intelligence.

[0081] In some embodiments, the sealing portion 122 may include a connecting structure 1221 and an elastic sealing structure 1222 disposed at one end of the connecting structure 1221. The connecting structure 1221 may be connected to the driving end of the electronic control module or the manually controlled operating portion 121. The elastic sealing structure 1222 may be an elastic structure made of rubber, silicone or other materials disposed at one end of the connecting structure 1221.

[0082] In the above embodiment, the shape of the second vent 1112 includes one of a circular shape, a conical shape and a square shape, and the elastic sealing structure 1222 matches the shape of the second vent 1112 , which is not detailed in the present disclosure.

[0083] In some embodiments, the soft sealing member 131, the deformable connecting member 132 and the counterweight member 133 form an integrated structure to improve the structural reliability and processing convenience of the sealing assembly 13. The soft sealing member 131, the deformable connecting member 132 and the counterweight member 133 can be made of rubber, silicone and other materials, which are not limited in the present disclosure.

[0084] The deformable connector 132 may be a rod-shaped structure to support the counterweight 133. When the switch assembly 10 moves with the device, the counterweight 133 will deform the deformable connector 132 due to gravity, and pull the soft sealing member 131 to open the slit 1311. When the device is stationary, the deformable connector 132 supports the counterweight 133 and does not pull the soft sealing member 131, so the slit 1311 is in a closed state.

[0085] In the above embodiment, the slit 1311 divides the soft sealing member 131 into a first part and a second part, and the deformable connector 132 is arranged in the first part or the second part. The deformable connector 132 is arranged in the first part or the second part so as to pull one side of the slit 1311 to facilitate the opening of the slit 1311. The slit 1311 can be arranged in the middle position of the soft sealing member 131 so that the first part or the second part is symmetrical. Alternatively, the slit 1311 can also be arranged in other positions of the soft sealing member 131 so that the size of the first part or the second part is different.

[0086] In some embodiments, the slit 1311 includes a straight line structure and / or a curved line structure.

[0087] In some embodiments, Figure 12-14 As shown, the counterweight 133 can be a cuboid, a sphere, a cylinder, or a polyhedron.

[0088] See also Fig.15As shown, the embodiment of the present disclosure further provides a cleaning device, including a cleaning brush 80 and the cleaning water tank 100 described in the above embodiments and implementation methods, wherein the cleaning brush 80 is detachably connected to the water tank housing 30 of the cleaning water tank 100. Optionally, the cleaning brush 80 is provided with a connecting component 81, which is matched and connected with the connecting portion 60 of the cleaning water tank 100 to realize the assembly of the cleaning brush 80 and the cleaning water tank 100. Optionally, the cleaning device can be a sweeping robot, a window cleaning robot, a handheld sweeper, etc., which is not limited by the present disclosure.

[0089] Since the switch assembly 10 is assembled to form a module, it is easy to install in the water storage chamber 31 of different cleaning equipment. The housing 11 of the switch assembly 10 is provided with a first cavity 111, and the cavity wall surrounding the first cavity 111 is provided with a first vent 1111 and a second vent 1112. The second vent 1112 can be opened or closed by controlling the blocking switch 12, and the first vent 1111 can be opened or closed with the movement or stillness of the counterweight 133. The water storage chamber 31 can complete the drainage operation from the water outlet when the internal and external airways are connected, and the blocking switch 12 and the sealing assembly 13 are dually controlled to realize the opening and closing of the airways inside and outside the water storage chamber 31. The sealing assembly 13 will only open the slit 1311 due to the inertia of the counterweight 133 during the movement, thereby avoiding the leakage of the water storage chamber 31 when the blocking switch 12 or the water outlet switch of the water storage chamber is forgotten to be closed or the blocking fails. The present disclosure ensures the sealing effect of the water storage chamber 31 in a non-drainage state through a simple structural setting, thereby improving the user experience of the water storage chamber 31 and the cleaning equipment using the water storage chamber 31.

[0090] Taking the clean water tank disclosed in the present invention as an external clean water tank, and applying it to a vacuum cleaner as an example, when a user uses the external clean water tank disclosed in the present invention on a vacuum cleaner, he can choose to add water to the water tank shell by opening the plug cover of the water filling port on the side, or choose to open the plug cover of the water filling port directly above to add water to the water tank shell. The choice can be flexibly made according to the actual situation of the household pool faucet, etc., to improve the user experience. After adding water, the water filling port is sealed and closed by the plug cover. After the water is added, the external clean water tank is placed upright on the ground, and the connecting component at the rear end of the cleaning floor brush of the vacuum cleaner (such as a built-in iron sheet) is magnetically connected to the magnet built into the water tank shell, or the connecting component at the rear end of the floor brush is inserted into the corresponding position of the water tank shell, and a physical connection is achieved through a snap fastener, an adhesive, etc.

[0091] In actual application, the user can move the operating part of the switch assembly provided on the water tank shell to the open position, driving the slider and the sealing part (that is, the ejector structure) to be moved away, so that the first cavity and the second cavity, that is, the left and right cavities are connected. When the user pushes and pulls the cleaning device to move in various directions, the counterweight swings under the action of inertia, and the swinging force is transmitted to the soft sealing part through the deformable connecting part. The slit on the soft sealing part functions like a duckbill valve. The slit is opened by external force, and the outside air enters the first cavity from the air holes on the bottom, and then enters the second cavity through the second vent, and finally enters the water storage cavity, realizing a pressure difference between the inside and outside of the water storage cavity. Under the action of the pressure difference, water is discharged from the water outlet at the bottom of the water tank to wet the mop set at the bottom.

[0092] After using the vacuum cleaner, the user moves the operating part of the switch assembly to the closed position. At this time, the blocking part completely blocks the second vent, and the first cavity and the second cavity are blocked, isolating the outside air from entering the water storage cavity. The external air pressure of the water storage cavity is greater than the internal air pressure, so that the water in the water storage cavity will not leak from the water outlet. Even if the user forgets to turn off the switch and remove the towed water tank after use, the counterweight and the deformable connector will return to the original vertical static state without inertia, and the soft sealing part made of soft material will return to a completely sealed state, isolating the outside air from entering, and can also prevent the water in the water storage cavity from leaking.

[0093] In order to prevent the water tank from stinking, users are often required to clean the mop after using the water tank and pour out the remaining clean water in the water tank. Before using the water tank next time, users need to refill the water tank. Therefore, after removing the water tank, users can also choose to fill the water from the side or the top. According to experience and the generally long and flat characteristics of water tanks, pouring water from the top is difficult and unclean. Pouring water from the narrow side can greatly improve the problem.

[0094] The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the scope of protection of the present disclosure.
