Description

Technical Field

[0001] This application relates to the technical field of environmental cleaning equipment, and particularly relates to a sewage tank and a cleaning device. Background Art

[0002] With the development of technology and the improvement of living standards, household cleaning equipment such as vacuum cleaners, floor mopping machines, and sweeping robots have become more and more popular, and their functions have also become more and more diverse.

[0003] The cleaning device includes a vacuum suction main unit, a sewage tank, and a floor brush. The vacuum suction main unit is connected to the sewage tank, the sewage tank is connected to the floor brush, and a dust suction port is provided at the bottom of the floor brush. When the user pushes the floor brush to move on the ground, the garbage and sewage on the ground are sucked into the sewage tank through the suction of the vacuum suction main unit from the dust suction port, so as to temporarily store the dirt in the sewage tank. In the related art, the sewage tank includes a box body, a box cover, and a filter element. The box cover can be covered on the upper end of the box body to facilitate opening or closing the box body. The filter element is connected to the box cover and extends into the box body. However, when the amount of sewage in the box body is relatively large, the filter element together with the box cover is easily separated from the box body. Summary of the Utility Model

[0004] Based on this, this application provides a sewage tank and a cleaning device. The sewage tank locks the cover body and the box body by setting a locking unit to prevent the cover body and the box body from separating when there is more sewage in the box body.

[0005] In a first aspect, this application provides a sewage tank, including a box body and a box cover assembly. The box cover assembly includes a cover body and a locking unit, and the cover body covers the box body;

[0006] The locking unit includes an unlocking member, a locking member, a first elastic member, and a second elastic member. The two ends of the first elastic member in the direction of its elastic force are connected to the unlocking member and the cover body, and the two ends of the second elastic member in the direction of its elastic force are connected to the locking member and the cover body;

[0007] The unlocking member is configured to move towards the locking member under an external force to drive the locking member to be separated from the connection with the box body, or the unlocking member moves away from the locking member under the elastic force of the first elastic member, and the locking member is connected to the box body under the elastic force of the second elastic member.

[0008] The sewage tank provided by the present application includes a box body and a box cover assembly. The box cover assembly includes a cover body and a locking unit. The locking unit includes an unlocking member, a locking member, a first elastic member, and a second elastic member. The box body is provided for recycling sewage, the cover body is provided for opening or closing the box body, the locking member is provided for locking the cover body and the box body to prevent the cover body and the box body from separating when there is a large amount of sewage in the box body. The second elastic member is provided for providing an elastic force to the locking member to enable the locking member to be reliably connected to the box body. The unlocking member is provided for driving the locking member to move under an external force, so that the locking member is disengaged from the box body, thereby unlocking the cover body and the box body. The first elastic member is provided for providing an elastic force to the unlocking member to drive the unlocking member to reset after the external force disappears. Thus, the locking of the cover body and the box body in the sewage tank provided by the embodiments of the present application is relatively simple and reliable, which can prevent the cover body and the box body from separating when there is a large amount of sewage in the box body, and the unlocking of the cover body and the box body is relatively convenient.

[0009] In a possible implementation manner, the sewage tank further includes a first sealing member, and the first sealing member abuts between the inner side wall of the box body and the outer side wall of the cover body.

[0010] In this way, after the first sealing member abuts between the box body and the cover body, the first sealing member can seal the gap between the box body and the cover body, and the first sealing member can increase the friction force between the box body and the cover body, thereby preventing the cover body from separating from the box body.

[0011] In a possible implementation manner, the unlocking member and the locking member are arranged along a first direction. The moving direction of the unlocking member is along the first direction, and the moving direction of the locking member is along a second direction;

[0012] Wherein, the first direction and the second direction are arranged at an angle.

[0013] In this way, when an external force acts on the unlocking member, the external force drives the unlocking member to move along the first direction towards the locking member, and then drives the locking member to move along the second direction away from the box body, thereby causing the locking member to be disengaged from the box body, and unlocking the cover body and the box body. When the external force acting on the unlocking member disappears, the unlocking member moves along the first direction away from the locking member under the elastic force of the second elastic member, and the unlocking member is disengaged from the locking member, and the locking member resets along the second direction under the elastic force of the first elastic member.

[0014] In a possible implementation manner, the first direction is along the height direction of the box body.

[0015] In this way, when the cleaning device is performing cleaning work, this pressing method is not conducive to unlocking the cover body and the box body, thereby preventing the cover body from separating from the box body when the sewage tank is working. When the sewage tank is removed from the device main body, the pressing method from top to bottom is more helpful for the user to apply force, thereby improving the operation convenience.

[0016] In a possible implementation, the number of the locking members and the second elastic members is two. The two locking members are arranged at intervals along the second direction, and each second elastic member is correspondingly connected between the cover body and each locking member.

[0017] In this way, both of the two locking members are clamped with the box body, which can improve the connection reliability between the cover body and the box body. And the two second elastic members are correspondingly connected between the cover body and the two locking members respectively, so that each locking member can be reliably clamped with the box body under the elastic force of the corresponding second elastic member.

[0018] In a possible implementation, the box body includes a main body and a first clamping portion. The first clamping portion is connected to one end of the main body facing the cover body. The locking member has a second clamping portion, and the second clamping portion is clamped with the first clamping portion.

[0019] In this way, the main body is used to hold sewage. When the first clamping portion is clamped with the second clamping portion, the cover body and the box body can be locked. Or when the first clamping portion is disengaged from the second clamping portion, the cover body and the box body can be unlocked, so that the locking member and the box body are detachably connected.

[0020] In a possible implementation, the unlocking member includes a pressing portion and a first abutting portion connected to each other. The locking member further includes a second abutting portion connected to the second clamping portion. The first abutting portion has a first mating surface, and the second abutting portion has a second mating surface. The first mating surface and the second mating surface are in mating abutment, and both the first mating surface and the second mating surface are inclined with respect to the first direction.

[0021] In this way, when an external force is applied to the pressing member along the first direction, the pressing member moves along the first direction. The external force is transmitted to the second mating surface through the first mating surface. Since both of them are inclined with respect to the first direction, the transmission direction of the external force can be changed, and then the locking member is driven to move along the second direction, so that the locking member is disengaged from the clamping connection with the box body.

[0022] In a possible implementation, the unlocking member further includes a first connecting portion. The first connecting portion and the first abutting portion are both connected to the side of the pressing portion facing the locking member. The first elastic member is sleeved on the first connecting portion, and the first elastic member abuts between the pressing portion and the cover body.

[0023] In this way, after the first elastic member is sleeved on the first connecting portion, the connection reliability between the first elastic member and the unlocking member can be improved, so that the unlocking member will not be disengaged from the first elastic member due to the excessive elastic force of the first elastic member.

[0024] In a possible implementation, the locking member further includes a second connecting portion. The second connecting portion and the second clamping portion are connected to both sides of the second abutting portion along the second direction. The second elastic member is sleeved on the second connecting portion, and the second elastic member abuts between the second abutting portion and the cover body.

[0025] In this way, after the second elastic member is sleeved on the second connecting portion, the connection reliability between the second elastic member and the locking member can be improved, so that the locking member will not be separated from the second elastic member due to excessive elastic force of the second elastic member.

[0026] In a possible implementation, the sewage tank further includes a filtering assembly, the filtering assembly is connected to the cover body, and the filtering assembly is located inside the tank body.

[0027] In this way, the filtering assembly can filter out solid garbage to prevent the solid garbage from flowing to the device main body along with the air flow.

[0028] In a possible implementation, the filtering assembly includes a water guiding member and a second sealing member, the water guiding member is connected to the cover body, and the second sealing member abuts between the water guiding member and the tank body.

[0029] In this way, after the second sealing member abuts between the water guiding member and the tank body, the first sealing member can seal the gap between the tank body and the cover body, the second sealing member can also increase the friction force between the water guiding member and the tank body, and since the water guiding member is connected to the cover body, it can prevent the cover body from separating from the tank body due to a large amount of sewage in the tank body.

[0030] In a second aspect, the present application further provides a cleaning device, including a device main body and the sewage tank provided in the first aspect above, and the sewage tank is connected to the device main body.

[0031] In addition to the technical problems solved by the embodiments of the present application described above, the technical features constituting the technical solutions, and the beneficial effects brought by these technical features of the technical solutions, other technical problems that the sewage tank and the cleaning device provided by the present application can solve, other technical features included in the technical solutions, and the beneficial effects brought by these technical features will be further described in detail in the specific implementation manners.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this application without creative efforts belong to the scope of protection of this application. The following will explain the embodiments of this application in detail with reference to the accompanying drawings.

[0050] In the description of this application, it should be noted that unless otherwise clearly specified and defined, the terms "install", "connect", and "couple" should be understood in a broad sense. For example, it can be a fixed connection, or an indirect connection through an intermediate medium, or the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0051] In the description of this application, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships in the accompanying drawings. It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to this application.

[0052] The terms "first", "second", "third" (if any) in the specification, claims, and the above accompanying drawings of this application are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of this application described here can be implemented in an order other than those illustrated or described here.

[0053] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or display that includes a series of steps or units does not necessarily limit to those clearly listed steps or units, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or displays.

[0054] The cleaning device includes a vacuuming main unit, a sewage tank, and a floor brush. The vacuuming main unit is connected to the sewage tank, and the sewage tank is connected to the floor brush. A suction port is provided at the bottom of the floor brush. When the user pushes the floor brush to move on the ground, the suction force of the vacuuming main unit sucks the garbage, sewage, etc. on the ground through the suction port into the sewage tank to temporarily store the dirt in the sewage tank. In the related art, the sewage tank includes a box body, a box cover, and a filtering member. The box cover can be connected to the upper end of the box body for easy opening or closing of the box body. The filtering member is connected to the box cover and extends into the box body. However, when the amount of sewage in the box body is relatively large, the filtering member together with the box cover is likely to be separated from the box body.

[0055] In view of the above problems, an embodiment of the present application provides a sewage tank and a cleaning device. The cover body of the sewage tank is locked to the box body through a locking unit to prevent the cover body from being separated from the box body when there is a large amount of sewage in the box body.

[0056] The following details the implementation manners of the sewage tank and the cleaning device provided by the embodiments of the present application with reference to the accompanying drawings.

[0057] Refer to Figure 1 As shown, an embodiment of the present application provides a cleaning device, including a sewage tank and a device main unit. The sewage tank is connected to the device main unit.

[0058] In addition, the cleaning device may further include a floor brush. The sewage tank is connected to the floor brush and the device main unit. When the device main unit works, it can generate a suction force and provide it to the floor brush and the sewage tank. After the floor brush contacts the surface to be cleaned, it can recover the sewage on the surface to be cleaned into the sewage tank.

[0059] Refer to Figures 1 to 7 As shown, the sewage tank provided by the embodiment of the present application includes a box body 100 and a box cover assembly 200. The box cover assembly 200 includes a cover body 210 and a locking unit 220. The cover body 210 is disposed on the box body 100.

[0060] The locking unit 220 includes an unlocking member 221, a locking member 222, a first elastic member 223, and a second elastic member 224. Two ends in the elastic force direction of the first elastic member 223 are connected to the unlocking member 221 and the cover body 210, and two ends in the elastic force direction of the second elastic member 224 are connected to the locking member 222 and the cover body 210.

[0061] The unlocking member 221 is configured to move towards the locking member 222 under an external force to drive the locking member 222 to be separated from the connection with the box body 100. Alternatively, the unlocking member 221 moves away from the locking member 222 under the elastic force of the first elastic member 223, and the locking member 222 is connected to the box body 100 under the elastic force of the second elastic member 224.

[0062] In the present application, the box body 100 is used for recycling sewage. The cover body 210 is connected to the box body 100 to close the box body 100. Or when it is necessary to clean the sewage in the box body 100, the cover body 210 is opened to pour out the sewage. The locking unit 220 is used to lock the cover body 210 on the box body 100 to prevent the cover body 210 from detaching from the box body 100. Or when it is necessary to open the cover body 210, the locking unit 220 unlocks the cover body 210 and the box body 100.

[0063] Specifically, the locking unit 220 may include an unlocking member 221, a locking member 222, a first elastic member 223, and a second elastic member 224. The locking member 222 is used to lock the cover body 210 and the box body 100. The second elastic member 224 is used to provide an elastic force for the locking member 222. The elastic force of the second elastic member 224 points to the locking member 222. That is to say, the locking member 222 can move outward toward the outside of the box body 100 under the elastic force of the second elastic member 224 so that the locking member 222 is connected to the box body 100, and then the cover body 210 is locked on the box body 100, thereby preventing the cover body 210 from detaching from the box body 100 due to a large amount of sewage in the box body 100. Thus, the connection between the cover body 210 and the box body 100 is relatively reliable.

[0064] The unlocking member 221 is used to unlock the cover body 210 and the box body 100. The second elastic member 224 is used to provide an elastic force for the unlocking member 221. The elastic force of the second elastic member 224 points to the unlocking member 221. When an external force acts on the unlocking member 221, the external force can be transmitted to the locking member 222 through the unlocking member 221, and then the locking member 222 is disconnected from the box body 100, thereby unlocking the cover body 210 and the box body 100. When the external force acting on the unlocking member 221 disappears, the unlocking member 221 can be reset under the elastic force of the first elastic member 223, and the locking member 222 can be reset under the elastic force of the second elastic member 224. Thus, the box body 100 can be conveniently opened to clean the sewage in the box body 100.

[0065] The sewage tank provided by the embodiment of the present application includes a tank body 100 and a tank cover assembly 200. The tank cover assembly 200 includes a cover body 210 and a locking unit 220. The locking unit 220 includes an unlocking member 221, a locking member 222, a first elastic member 223, and a second elastic member 224. By providing the tank body 100 for recycling sewage, by providing the cover body 210 for opening or closing the tank body 100, by providing the locking member 222 for locking the cover body 210 and the tank body 100 to prevent the cover body 210 and the tank body 100 from separating when there is a large amount of sewage in the tank body 100, by providing the second elastic member 224 for providing an elastic force to the locking member 222 so that the locking member 222 is reliably connected to the tank body 100, by providing the unlocking member 221 for driving the locking member 222 to move under an external force, and then enabling the locking member 222 to be disengaged from the tank body 100, thereby unlocking the cover body 210 and the tank body 100, and by providing the first elastic member 223 for providing an elastic force to the unlocking member 221 to drive the unlocking member 221 to reset after the external force disappears. Thus, in the sewage tank provided by the embodiment of the present application, the locking of the cover body 210 and the tank body 100 is relatively simple and reliable, which can prevent the cover body 210 and the tank body 100 from separating when there is a large amount of sewage in the tank body 100, and moreover, the unlocking of the cover body 210 and the tank body 100 is relatively convenient.

[0066] Referring to Figure 2 、 Figure 5 and Figure 7 As shown, in a possible implementation manner, the sewage tank further includes a first sealing member 230, and the first sealing member 230 abuts between the inner side wall of the tank body 100 and the outer side wall of the cover body 210.

[0067] It can be understood that after the first sealing member 230 abuts between the tank body 100 and the cover body 210, the first sealing member 230 can seal the gap between the tank body 100 and the cover body 210, and moreover, the first sealing member 230 can increase the friction force between the tank body 100 and the cover body 210, thereby preventing the cover body 210 from separating from the tank body 100.

[0068] Referring to Figure 4 As shown, in a possible implementation manner, the unlocking member 221 and the locking member 222 are arranged along a first direction. The moving direction of the unlocking member 221 is along the first direction, and the moving direction of the locking member 222 is along a second direction.

[0069] Wherein, the first direction and the second direction are arranged at an angle. The first direction can refer to the X direction in the attached drawing, and the second direction can refer to the Y direction in the attached drawing.

[0070] In this way, when an external force acts on the unlocking member 221, the external force drives the unlocking member 221 to move towards the locking member 222 in the first direction, and then drives the locking member 222 to move away from the box body 100 in the second direction, thereby causing the locking member 222 to disconnect from the box body 100, and thus unlocking the cover body 210 and the box body 100.

[0071] When the external force acting on the unlocking member 221 disappears, the unlocking member 221 moves away from the locking member 222 in the first direction under the elastic force of the second elastic member 224. Moreover, the unlocking member 221 disconnects from the locking member 222, and the locking member 222 resets in the second direction under the elastic force of the first elastic member 223.

[0072] In a possible implementation manner, the first direction is along the height direction of the box body 100. That is to say, in this setting manner, the user needs to press the unlocking member 221 along the height direction of the box body 100 to apply an external force to the unlocking member 221 to unlock the cover body 210 and the box body 100. When the sewage tank is connected to the device main body, for example, when the cleaning device is performing cleaning work, since the unlocking member 221 is located inside the cleaning device, this pressing method is not conducive to unlocking the cover body 210 and the box body 100. In this way, it can prevent the cover body 210 from separating from the box body 100 when the sewage tank is working. When the sewage tank is removed from the device main body, for example, when the sewage in the sewage tank needs to be cleaned, the pressing method from top to bottom is more helpful for the user to apply force, thereby improving the operation convenience.

[0073] In some embodiments, the number of both the locking member 222 and the second elastic member 224 is two. The two locking members 222 are arranged at intervals in the second direction, and each second elastic member 224 is correspondingly connected between the cover body 210 and each locking member 222.

[0074] In this way, both of the two locking members 222 are snap-connected to the box body 100, which can improve the connection reliability between the cover body 210 and the box body 100. And the two second elastic members 224 are correspondingly connected between the cover body 210 and the two locking members 222 respectively, so that each locking member 222 can be reliably snap-connected to the box body 100 under the elastic force of the corresponding second elastic member 224. Moreover, the moving directions of the two locking members 222 are opposite when locking and unlocking.

[0075] Refer to Figure 2 、 Figure 6 And Figure 8 As shown, in specific implementation, the box body 100 includes a main body 110 and a first snap-connection portion 120. The first snap-connection portion 120 is connected to one end of the main body 110 facing the cover body 210. The locking member 222 has a second snap-connection portion 2221, and the second snap-connection portion 2221 is snap-connected to the first snap-connection portion 120.

[0076] Thus, the main body 110 is used to hold sewage. When the first engaging portion 120 is engaged with the second engaging portion 2221, the locking cover 210 and the box body 100 can be connected. Or, when the first engaging portion 120 is disengaged from the second engaging portion 2221, the unlocking cover 210 and the box body 100 can be disconnected, thereby enabling a detachable connection between the locking member 222 and the box body 100.

[0077] Referring to Figures 8 to 11 As shown, in some embodiments, to make the moving directions of the unlocking member 221 and the locking member 222 different, the unlocking member 221 includes a pressing portion 2211 and a first abutting portion 2212 connected to each other. The locking member 222 further includes a second abutting portion 2222 connected to the second engaging portion 2221. The first abutting portion 2212 has a first mating surface 2212a, and the second abutting portion 2222 has a second mating surface 2222a. The first mating surface 2212a and the second mating surface 2222a are in mating abutment, and both the first mating surface 2212a and the second mating surface 2222a are inclined with respect to the first direction.

[0078] With such a setting, when an external force is applied to the pressing portion 2211 in the first direction, the pressing portion 2211 moves in the first direction. The external force is transmitted to the second mating surface 2222a through the first mating surface 2212a. Since both are inclined with respect to the first direction, the transmission direction of the external force can be changed, and then the locking member 222 is driven to move in the second direction, so that the locking member 222 is disengaged from the box body 100.

[0079] Referring to Figure 8 And Figure 9 As shown, in a possible implementation, the unlocking member 221 further includes a first connecting portion 2213. Both the first connecting portion 2213 and the first abutting portion 2212 are connected to the side of the pressing portion 2211 facing the locking member 222. The first elastic member 223 is sleeved on the first connecting portion 2213, and the first elastic member 223 abuts between the pressing portion 2211 and the cover 210.

[0080] In this way, after the first elastic member 223 is sleeved on the first connecting portion 2213, the connection reliability between the first elastic member 223 and the unlocking member 221 can be improved, so that the unlocking member 221 will not be disengaged from the first elastic member 223 due to the excessive elastic force of the first elastic member 223.

[0081] Referring to Figure 8 And Figure 11As shown, in some embodiments, the locking member 222 further includes a second connecting portion 2223. The second connecting portion 2223 and the second engaging portion 2221 are connected to two sides of the second abutting portion 2222 along the second direction. The second elastic member 224 is sleeved on the second connecting portion 2223, and the second elastic member 224 abuts between the second abutting portion 2222 and the cover body 210.

[0082] With this arrangement, after the second elastic member 224 is sleeved on the second connecting portion 2223, the connection reliability between the second elastic member 224 and the locking member 222 can be improved, so that the locking member 222 will not be separated from the second elastic member 224 due to excessive elastic force of the second elastic member 224.

[0083] In a possible implementation, the sewage tank further includes a filtering assembly 300. The filtering assembly 300 is connected to the cover body 210 and is located inside the box body 100.

[0084] Refer to Figure 2 As shown, it should be noted that when the cleaning device is working, the surface to be cleaned not only has liquids such as sewage, but also solid garbage. These solid garbage will also be collected in the sewage tank. However, when the air flow continues to flow towards the device main body, it is necessary to set up to filter out the solid garbage to prevent the solid garbage from flowing along with the air flow and causing jamming of the device main body. Therefore, setting the filtering assembly 300 in the box body 100 can filter out the solid garbage.

[0085] Refer to Figure 2 、 Figure 5 、 Figure 7 And Figure 12 As shown, in a specific implementation, the filtering assembly 300 includes a water guiding member 310 and a second sealing member 320. The water guiding member 310 is connected to the cover body 210, and the second sealing member 320 abuts between the water guiding member 310 and the box body 100.

[0086] In this way, after the second sealing member 320 abuts between the water guiding member 310 and the box body 100, the first sealing member 230 can seal the gap between the box body 100 and the cover body 210. The second sealing member 320 can also increase the friction force between the water guiding member 310 and the box body 100. And since the water guiding member 310 is connected to the cover body 210, it can prevent the cover body 210 from separating from the box body 100 due to a large amount of sewage in the box body 100.

[0087] It should be noted that the water guiding member 310 can divide the inner cavity of the main body 110 into a sewage cavity and a mixing cavity. That is, the mixture of sewage and solid garbage is mainly located in the mixing cavity, and there is basically no solid garbage in the sewage cavity. In this way, the solid garbage can be intercepted to prevent the solid garbage from flowing to the device main body along with the air flow.

[0088] Refer toFigure 7 As shown, in addition, the lid assembly 200 may further include a cover plate 240. The cover plate 240 is connected to the lid body 210, and the cover plate 240 and the lid body 210 together define a receiving cavity, and the locking unit 220 is disposed in the receiving cavity.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
