Description

Technical Field

[0001] This application relates to the field of environmental cleaning electrical appliances, and in particular to a water tank structure and cleaning equipment. Background Technology

[0002] In the prior art, floor scrubbing machines include a machine body and a wastewater tank. The wastewater tank mainly includes a wastewater tank body, a wastewater tank cover, and a sealing structure. The wastewater tank cover can be placed on the open end of the wastewater tank body, and the sealing structure is connected to the wastewater tank cover so that the wastewater tank cover is sealed to the wastewater tank body through the sealing structure, thereby improving the sealing performance of the wastewater tank.

[0003] However, due to the interference fit between the sealing structure and the sewage tank body, it is necessary to pull the sewage tank cover off the sewage tank body with force, which causes sewage to overflow. When the sewage tank cover is put back into the sewage tank body, it is necessary to press it in with force, making assembly difficult and thus making the disassembly and assembly of the sewage tank cover quite difficult. Utility Model Content

[0004] Based on this, this application provides a water tank structure and a cleaning device to address the shortcomings of related technologies.

[0005] In a first aspect, this application provides a water tank structure, comprising:

[0006] The box has a receiving cavity, and one end of the receiving cavity has an outlet;

[0007] A box cover assembly, comprising a box cover, at least one seal and at least one retaining ring, wherein at least a portion of the box cover, the seal and the retaining ring are disposed in a receiving cavity via an outlet, and the seal and the retaining ring are both disposed circumferentially along the outlet and are both connected to the box cover.

[0008] The retaining ring is positioned around the inner circumference of the seal and is configured to move the seal toward or away from the sidewall of the receiving cavity.

[0009] The water tank structure provided in this application embodiment improves the sealing performance of the water tank structure by providing a receiving cavity for containing liquid, an outlet for easy liquid pouring, a tank cover for closing the outlet, and a sealing element that abuts against the side wall of the receiving cavity and the tank cover. Because the inner side of the sealing element has a retaining ring, the expansion or contraction of the retaining ring can move the sealing element, thereby flexibly adjusting the fit between the sealing element and the side wall of the receiving cavity. Thus, during operation of the water tank structure, expanding the retaining ring creates an interference fit between the sealing element and the side wall of the receiving cavity, improving the sealing performance. Conversely, during disassembly and installation of the tank cover, contracting the retaining ring creates a clearance fit between the sealing element and the side wall of the receiving cavity, reducing friction and minimizing the user's operating effort, while preventing sewage leakage due to excessive operating force.

[0010] In one possible implementation, the lid assembly further includes a first slider and a second slider, with a retaining ring connected to the second slider;

[0011] The first slider and the second slider are slidably connected, and the second slider and the first slider have a first connection state and a second connection state;

[0012] When the second sliding member switches from the first connection state to the second connection state with the first sliding member, the second sliding member drives the retaining ring to retract away from the sealing member.

[0013] When the second sliding member switches from the second connection state to the first connection state with the first sliding member, the second sliding member drives the retaining ring to expand toward the sealing member.

[0014] Thus, when a force is applied to the first sliding member and causes it to slide relative to the second sliding member, so that the first and second sliding members are in a first connection state, the second sliding member can drive the retaining ring to expand outward, thereby causing the seal to expand outward, thus causing the seal to have an interference fit with the side wall of the receiving cavity.

[0015] When a force is applied to the first sliding member and causes it to slide relative to the second sliding member, so that the first and second sliding members are in a second connection state, the second sliding member can drive the retaining ring to retract inward, thereby causing the seal to retract inward, which in turn causes the seal to fit with the side wall of the receiving cavity, thereby reducing the friction between the two and facilitating the quick assembly and disassembly of the cover assembly.

[0016] In one possible implementation, a first slider is inserted into a second slider, and the first slider has a first abutting surface and a second abutting surface on the side facing the sidewall of the receiving cavity, with the first abutting surface being disposed closer to the sidewall of the receiving cavity than the second abutting surface.

[0017] The second sliding member has a third abutting surface and a fourth abutting surface, with the third abutting surface disposed away from the side wall of the receiving cavity relative to the fourth abutting surface;

[0018] When the third contact surface abuts against the first contact surface, the second sliding member and the first sliding member are in a first connection state; when the fourth contact surface abuts against the second contact surface, the second sliding member and the first sliding member are in a second connection state.

[0019] Thus, during the transition from the second connection state to the first connection state between the first and second sliding members, the first sliding member can drive the second sliding member to move towards the side wall of the receiving cavity, thereby causing the retaining ring to move towards the side wall of the receiving cavity, and consequently causing the seal to move towards the side wall of the receiving cavity. At this time, both the retaining ring and the seal are in an expanded state, and the seal is in an interference fit with the side wall of the receiving cavity.

[0020] During the connection between the first and second sliding members, and the process of switching from the first connection state to the second connection state, the second sliding member moves away from the side wall of the receiving cavity. The retaining ring and the sealing member also move away from the side wall of the receiving cavity due to their own elasticity, thereby causing the retaining ring and the sealing member to be in a contracted state, thus making the sealing member and the side wall of the receiving cavity fit with a clearance.

[0021] In one possible implementation, the first slider further includes an abutment block located at the end of the first slider facing the outlet;

[0022] The water tank structure also includes an elastic reset member, the two ends of which abut against the abutment block and the tank cover in the direction of elastic force, and the direction of elastic force of the elastic reset member points towards the abutment block.

[0023] In this way, pressure can be applied to the abutment block, thereby causing the first sliding member to slide relative to the second sliding member, and thus causing the first sliding member and the second sliding member to switch to the first connection state. During this process, the second sliding member can drive the retaining ring to move toward the side wall of the receiving cavity, and then the retaining ring can drive the sealing member to move toward the side wall of the receiving cavity, thereby causing the sealing member to be in a sealing state.

[0024] After the pressure is released, the elastic force of the elastic reset member can cause the first sliding member to slide relative to the second sliding member, thereby switching the first and second sliding members to the second connection state. During this process, the second sliding member moves away from the side wall of the receiving cavity, and the retaining ring and the seal also move away from the side wall of the receiving cavity, thereby making the seal in the disassembled state.

[0025] In one possible implementation, the retaining ring is an open ring.

[0026] In this way, when the open ring expands, the opening of the open ring increases, and when the open ring contracts, the opening of the open ring decreases, thus allowing the retaining ring to expand and contract freely, and the retaining ring is not easily damaged after repeated use.

[0027] In one possible implementation, the lid assembly further includes a handle located outside the receiving cavity and rotatably connected to the lid to switch between a first position and a second position. The handle abuts against a first slider to move the first slider relative to the second slider.

[0028] When the handle is in the first position, the second slider and the first slider are in a first connection state; when the handle is in the second position, the second slider and the first slider are in a second connection state.

[0029] In this way, by switching the position of the handle, the connection state of the first and second sliding parts can be controlled, thereby controlling the expansion or contraction of the retaining ring. This control process does not consume electrical energy, thus reducing the energy consumption of the cleaning equipment.

[0030] In one possible implementation, the handle includes a handle part and a rotating part connected to each other, the rotating part being rotatably connected to the lid;

[0031] The rotating part abuts against the first sliding member.

[0032] Thus, when the user rotates the handle to switch between the first and second positions, the rotating part can be rotated relative to the lid, causing different positions of the rotating part to abut against the first sliding member, thereby causing the first abutting surface to abut against the third abutting surface, or the second abutting surface to abut against the fourth abutting surface.

[0033] In one possible implementation, the rotating part has a rotating hole and a contact surface, and the cover has a rotating shaft that is rotatably connected to the rotating hole;

[0034] The contact surface surrounds the outer periphery of the rotating hole. The contact surface has a first abutment position and a second abutment position. The distance T1 from the first abutment position to the rotating hole and the distance T2 from the second abutment position to the rotating hole satisfy: T1 > T2.

[0035] When the first abutting position abuts against the first sliding member, the second sliding member and the first sliding member are in a first connection state; when the second abutting position abuts against the first sliding member, the second sliding member and the first sliding member are in a second connection state.

[0036] Thus, when the rotating part rotates, the contact surface also rotates relative to the abutting block. When the position of the abutting block abutting the contact surface changes from the first abutting position to the second abutting position, since the distance from the second abutting position to the rotating hole is less than the distance from the first abutting position to the rotating hole, the elastic force of the elastic reset member is greater than the pressure of the rotating part. The resultant force of the two forces points towards the abutting block, and the resultant force drives the first sliding member to slide relative to the second sliding member, thereby making the two put into the second connection state, which in turn causes the retaining ring to retract, thereby making the seal put into the disassembled state.

[0037] When the position of the abutting block abutting the contact surface changes from the second abutting position to the first abutting position, since the distance from the first abutting position to the rotating hole is greater than the distance from the second abutting position to the rotating hole, the elastic force of the elastic reset member is less than the pressure of the rotating part. The resultant force of the two forces is opposite to the abutting block, and the resultant force drives the first sliding member to slide relative to the second sliding member, thereby making the two in the first connection state, which in turn causes the retaining ring to expand outward, thereby making the sealing member in the sealing state.

[0038] In one possible implementation, two seals are spaced apart along the height of the water tank, with each seal corresponding to a retaining ring.

[0039] Thus, by setting two seals, the sealing performance of the water tank structure can be improved, and each seal is equipped with a corresponding retaining ring to allow the retaining ring to adjust the state of the seal, thereby making the sealing performance of the seal better, and the tank cover assembly is easier to disassemble and assemble.

Detailed Implementation

[0061] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0062] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0063] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0064] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0065] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0066] In existing technology, floor scrubbers include a machine body and a wastewater tank. The wastewater tank mainly consists of a tank body, a lid, and a sealing structure. The lid can be placed over the open end of the tank body, and the sealing structure is connected to the lid to create a sealed connection between the lid and the tank body, thereby improving the tank's sealing performance. However, due to the interference fit between the sealing structure and the tank body, removing the lid requires force, leading to wastewater overflow. Similarly, inserting the lid requires force, making assembly difficult and consequently, disassembling the lid quite challenging.

[0067] In view of the above problems, this application provides a water tank structure and a cleaning device. The water tank structure provides a retaining ring on the inner side of the seal, and the retaining ring can expand or contract, so that the seal can switch between a sealed state and a disassembled state. When the tank cover assembly is installed on the tank body, the retaining ring can be controlled to expand, so that the seal and the tank body have an interference fit, thereby improving the sealing performance of the water tank structure. When the tank cover assembly needs to be removed from or installed on the tank body, the retaining ring can be controlled to contract, so that the seal and the tank body have a clearance fit, thereby facilitating the quick disassembly and assembly of the tank cover assembly.

[0068] The following describes in detail the specific implementation of the water tank structure and cleaning equipment provided in the embodiments of this application, with reference to the accompanying drawings.

[0069] Reference Figure 1 , Figure 2 , Figure 3 As shown in the embodiment of this application, the cleaning equipment includes a water tank structure and a body, with the water tank structure connected to the body.

[0070] The water tank structure of this application embodiment can be applied to cleaning equipment. The water tank structure can be used to recycle wastewater generated during the wet mopping operation of the cleaning equipment. In order to facilitate cleaning of the water tank structure and avoid wastewater remaining in the water tank structure for too long and producing odor, the water tank structure can be detachably connected to the machine body so that users can clean the water tank structure after each use.

[0071] Reference Figure 3 , Figure 4 As shown, based on the above embodiments, this application also provides a water tank structure, including a tank body 100 and a tank cover assembly 200. The tank body 100 has a receiving cavity 110, and one end of the receiving cavity 110 has an outlet 111.

[0072] The box cover assembly 200 includes a box cover 210, at least one seal 220 and at least one retaining ring 230. At least a portion of the box cover 210, the seal 220 and the retaining ring 230 are disposed in the receiving cavity 110 via an outlet 111. The seal 220 and the retaining ring 230 are both arranged circumferentially along the outlet 111 and are both connected to the box cover 210.

[0073] The retaining ring 230 is disposed around the inner circumference of the seal 220, and the retaining ring 230 is configured to move the seal 220 toward or away from the side wall of the receiving cavity 110.

[0074] In this embodiment of the application, the receiving cavity 110 is used to receive liquid, and the outlet 111 is used to facilitate the entry of part of the lid 210 into the receiving cavity 110 so as to close the receiving cavity 110 by the lid 210, thereby preventing liquid leakage, and to facilitate the removal of the lid 210 to open the outlet 111, thereby facilitating the pouring out of the liquid in the receiving cavity 110.

[0075] Both the seal 220 and the retaining ring 230 are arranged circumferentially along the outlet 111. The seal 220 abuts between the side wall of the receiving cavity 110 and the tank cover 210 to improve the sealing performance of the water tank structure.

[0076] Since the retaining ring 230 is disposed inside the seal 220 and has both expanded and contracted states, it can move the seal 220 into a sealed state or a disassembled state, thus facilitating the control of the state of the seal 220 according to requirements. The retaining ring 230 can deform, and the deformation is recoverable, which facilitates switching between the expanded and contracted states.

[0077] In this way, when the cover assembly 200 and the box body 100 are normally installed, the seal 220 abuts against the side wall of the receiving cavity 110 and the cover 210. When the retaining ring 230 expands, it can drive the seal 220 to expand outward, thereby making the seal 220 and the receiving cavity 110 an interference fit relationship, which can effectively improve the sealing performance of the seal.

[0078] Alternatively, when it is necessary to disassemble or install the cover assembly 200, the open ring can be controlled to shrink, thereby causing the seal 220 to shrink inward, so that the seal 220 and the receiving cavity 110 are in a clearance fit relationship, thereby reducing the resistance to disassembly and assembly of the cover assembly 200. This makes it easier for the user to remove the cover assembly 200 from the box body 100 or install the cover assembly 200 onto the box body 100. During the disassembly and assembly process, the user's operating force is small, which can effectively prevent sewage leakage from the receiving cavity 110.

[0079] Compared with the prior art, in the embodiments of this application, the fit between the seal 220 and the housing 100 is dynamically adjustable, which can meet both the requirements of high sealing performance and the requirements of quick assembly and disassembly.

[0080] The cover 210 can be provided with an installation groove, and the seal 220 and the retaining ring 230 are both provided in the installation groove, so that the seal 220 and the retaining ring 230 can be installed on the cover 210.

[0081] The water tank structure provided in this embodiment improves the sealing performance of the water tank by providing a receiving cavity 110 for containing liquid, an outlet 111 for easy liquid pouring, a tank cover 210 for closing the outlet 111, and a sealing member 220 for abutting between the side wall of the receiving cavity 110 and the tank cover 210. Since a retaining ring 230 is provided on the inner side of the sealing member 220, the expansion or contraction of the retaining ring 230 can move the sealing member 220, thereby flexibly adjusting the fit between the sealing member 220 and the side wall of the receiving cavity 110. In this way, during the operation of the water tank structure, by expanding the retaining ring 230, the sealing element 220 and the side wall of the receiving cavity 110 can be made to have an interference fit, which helps to improve the sealing performance of the sealing element 220. Furthermore, when disassembling and installing the tank cover 210, by shrinking the retaining ring 230, the sealing element 220 and the side wall of the receiving cavity 110 can be made to have a clearance fit, which helps to reduce the friction between the sealing element 220 and the side wall of the receiving cavity 110. This helps to reduce the user's operating force and prevents sewage from leaking due to excessive operating force.

[0082] Reference Figures 4 to 12 As shown, in one possible implementation, the lid assembly 200 further includes a first sliding member 240 and a second sliding member 250, with a retaining ring 230 connected to the second sliding member 250. The first sliding member 240 and the second sliding member 250 are slidably connected, and the second sliding member 250 and the first sliding member 240 have a first connection state and a second connection state. Figures 7 to 9 This indicates the first connection state. Figures 10 to 12 This indicates the second connection state.

[0083] When the second sliding member 250 switches from the first connection state to the second connection state with the first sliding member 240, the second sliding member 250 causes the retaining ring 230 to contract away from the sealing member 220. When the second sliding member 250 switches from the second connection state to the first connection state with the first sliding member 240, the second sliding member 250 causes the retaining ring 230 to expand away from the sealing member 220.

[0084] It is understandable that, with the housing 100 as a reference, the retaining ring 230, the sealing member 220, and the second sliding member 250 can move in the inward and outward directions of the housing 100, and the first sliding member 240 can move in the up-down direction of the housing 100. The direction of movement of the first sliding member 240 is perpendicular to the direction of movement of the second sliding member 250.

[0085] Thus, when a force is applied to the first sliding member 240 and causes the first sliding member 240 to slide relative to the second sliding member 250, so that the first sliding member 240 and the second sliding member 250 are in the first connection state, the second sliding member 250 can drive the retaining ring 230 to expand outward, thereby driving the sealing member 220 to expand outward, thereby causing the sealing member 220 to have an interference fit with the side wall of the receiving cavity 110.

[0086] When a force is applied to the first sliding member 240 and causes the first sliding member 240 to slide relative to the second sliding member 250, so that the first sliding member 240 and the second sliding member 250 are in a second connection state, the second sliding member 250 can drive the retaining ring 230 to retract inward, thereby driving the sealing member 220 to retract inward, thereby causing the sealing member 220 to have a clearance fit with the side wall of the receiving cavity 110, which helps to reduce the friction between the two, thus facilitating the quick assembly and disassembly of the cover assembly 200.

[0087] In practice, users can manually apply force to the first sliding member 240 to drive it to slide, or an electric mechanism can be installed on the water tank structure to drive the first sliding member 240 to slide.

[0088] Reference Figure 13 As shown, in one possible implementation, the first slider 240 is inserted into the second slider 250. For example, the first slider 240 is a sliding rod, and the second slider 250 is a slider with a sliding hole. The shape of the sliding hole is adapted to the shape of the sliding rod. The accompanying drawings of this embodiment illustrate a scheme in which the sliding rod is a square rod.

[0089] The first sliding member 240 has a first abutment surface 241 and a second abutment surface 242 on the side facing the sidewall of the receiving cavity 110. The first abutment surface 241 is disposed closer to the sidewall of the receiving cavity 110 relative to the second abutment surface 242. The second sliding member 250 has a third abutment surface 251 and a fourth abutment surface 252. The third abutment surface 251 is disposed away from the sidewall of the receiving cavity 110 relative to the fourth abutment surface 252.

[0090] When the third abutting surface 251 abuts against the first abutting surface 241, the second sliding member 250 and the first sliding member 240 are in a first connection state. When the fourth abutting surface 252 abuts against the second abutting surface 242, the second sliding member 250 and the first sliding member 240 are in a second connection state.

[0091] Thus, during the transition from the second connection state to the first connection state between the first sliding member 240 and the second sliding member 250, the first sliding member 240 can drive the second sliding member 250 to move towards the side wall of the receiving cavity 110, thereby causing the retaining ring 230 to move towards the side wall of the receiving cavity 110, and thus causing the sealing member 220 to move towards the side wall of the receiving cavity 110. At this time, both the retaining ring 230 and the sealing member 220 are in an expanded state, and the sealing member 220 is in an interference fit with the side wall of the receiving cavity 110.

[0092] During the process of switching from the first connection state to the second connection state when the first slider 240 and the second slider 250 are connected, the second slider 250 moves away from the side wall of the receiving cavity 110. The retaining ring 230 and the sealing member 220 both move away from the side wall of the receiving cavity 110 due to their own elasticity, thereby causing the retaining ring 230 and the sealing member 220 to be in a contracted state, so that the sealing member 220 is in clearance fit with the side wall of the receiving cavity 110.

[0093] For example, the first abutting surface 241 and the third abutting surface 251 are both parallel to the length direction of the first sliding member 240, and the second abutting surface 242 and the fourth abutting surface 252 are both inclined relative to the length direction of the first sliding member 240, and the inclination directions are consistent.

[0094] Reference Figure 6 As shown, in one possible implementation, the first slider 240 further includes an abutment block 243 located at the end of the first slider 240 facing the outlet 111.

[0095] The lid assembly 200 also includes an elastic reset member 260, the two ends of which abut against the abutment block 243 and the lid 210 in the elastic direction, and the elastic direction of the elastic reset member 260 points towards the abutment block 243.

[0096] Understandably, pressure can be applied to the abutment block 243, thereby causing the first sliding member 240 to slide relative to the second sliding member 250, thus switching the first sliding member 240 and the second sliding member 250 to the first connection state. During this process, the second sliding member 250 can drive the retaining ring 230 to move toward the side wall of the receiving cavity 110, and the retaining ring 230 can drive the sealing member 220 to move toward the side wall of the receiving cavity 110, thereby causing the sealing member 220 to be in a sealing state.

[0097] After the pressure is released, the elastic force of the elastic reset member 260 can cause the first sliding member 240 to slide relative to the second sliding member 250, thereby switching the first sliding member 240 and the second sliding member 250 to the second connection state. During this process, the second sliding member 250 moves away from the side wall of the receiving cavity 110, and the retaining ring member 230 and the sealing member 220 also move away from the side wall of the receiving cavity 110, thereby making the sealing member 220 in the disassembled state.

[0098] In some embodiments, the retaining ring 230 is an open ring. In this way, when the open ring expands, the opening of the open ring increases, and when the open ring contracts, the opening of the open ring decreases, thereby allowing the retaining ring 230 to freely expand and contract, and the retaining ring 230 is not easily damaged after repeated use.

[0099] In some embodiments, an annular groove may be provided on the inner side of the seal 220, and the retaining ring 230 is placed in the annular groove so that the retaining ring 230 can drive the seal 220 to expand or contract synchronously.

[0100] Reference Figure 2 , Figures 3 to 5 As shown, in one possible implementation, the lid assembly 200 further includes a handle 270 located outside the receiving cavity 110 and rotatably connected to the lid 210 to switch between a first position and a second position. The handle 270 abuts against a first slider 240 to move the first slider 240 relative to a second slider 250.

[0101] When the handle 270 is in the first position, the second slider 250 and the first slider 240 are in a first connection state. When the handle 270 is in the second position, the second slider 250 and the first slider 240 are in a second connection state.

[0102] It should be noted that when the handle 270 is in the first position, the handle 270 is folded relative to the cover 210. When the handle 270 is in the second position, the handle 270 is unfolded relative to the cover 210. This makes it more convenient for users to operate and also makes it easier to install the water tank structure onto the machine body.

[0103] Since the handle 270 abuts against the first sliding member 240, the connection state of the first sliding member 240 and the second sliding member 250 can be changed. When the user needs to disassemble or assemble the lid assembly 200, the handle can be changed from a folded state to an unfolded state, making it easier for the user to hold the handle 270. During this process, the first sliding member 240 slides relative to the second sliding member 250 and switches to the second connection state, which allows the retaining ring 230 to retract inward, and the sealing member 220 to retract inward, thereby reducing the resistance to disassembly and assembly of the lid assembly 200.

[0104] During the installation of the water tank structure onto the machine body, the handle 270 can be changed from an unfolded state to a folded state. During this process, the handle 270 can cause the first sliding member 240 to slide relative to the second sliding member 250, switching to a first connection state. This causes the retaining ring 230 to expand outward, resulting in the sealing member 220 expanding outward and achieving a sealed state, thereby improving the sealing performance of the water tank structure. Folding the handle 270 reduces the volume of the water tank structure, facilitating its smooth installation onto the machine body.

[0105] Thus, by switching the position of the handle 270, the connection state of the first sliding member 240 and the second sliding member 250 can be controlled, thereby controlling the expansion or contraction of the retaining ring 230. This control process does not consume electrical energy, thereby reducing the energy consumption of the cleaning equipment.

[0106] Reference Figure 10 and Figure 14 As shown, in one possible implementation, the handle 270 includes a handle portion 271 and a rotating portion 272 connected to each other, the rotating portion 272 being rotatably connected to the lid 210. The rotating portion 272 abuts against the first sliding member 240.

[0107] Thus, when the user rotates the handle 271 to switch between the first and second positions, the rotating part 272 can be rotated relative to the lid 210, thereby causing different positions of the rotating part 272 to abut against the first sliding member 240, thereby causing the first abutting surface 241 to abut against the third abutting surface 251, or causing the second abutting surface 242 to abut against the fourth abutting surface 252.

[0108] Reference Figure 14 As shown, in one possible implementation, the rotating part 272 has a rotating hole 2721 and a contact surface 2722, and the cover 210 has a rotating shaft that is rotatably connected to the rotating hole 2721. The contact surface 2722 surrounds the outer periphery of the rotating hole 2721 and has a first abutment position 27221 and a second abutment position 27222. The distance T1 from the first abutment position 27221 to the rotating hole 2721 and the distance T2 from the second abutment position 27222 to the rotating hole 2721 satisfy: T1 > T2.

[0109] When the first abutting position 27221 abuts against the first sliding member 240, the second sliding member 250 and the first sliding member 240 are in a first connection state. When the second abutting position 27222 abuts against the first sliding member 240, the second sliding member 250 and the first sliding member 240 are in a second connection state.

[0110] Thus, when the rotating part 272 rotates, the contact surface 2722 also rotates relative to the abutting block 243. When the position of the abutting block 243 abutting the contact surface 2722 changes from the first abutting position 27221 to the second abutting position 27222, since the distance from the second abutting position 27222 to the rotating hole 2721 is less than the distance from the first abutting position 27221 to the rotating hole 2721, the elastic force of the elastic reset member 260 is greater than the pressure of the rotating part 272. The resultant force of the two forces points towards the abutting block 243, and the resultant force drives the first sliding member 240 to slide relative to the second sliding member 250, thereby making the two in the second connection state, thereby causing the retaining ring member 230 to retract inward, thereby making the sealing member 220 in the disassembled state.

[0111] When the position of the abutting block 243 abutting the contact surface 2722 changes from the second abutting position 27222 to the first abutting position 27221, since the distance from the first abutting position 27221 to the rotating hole 2721 is greater than the distance from the second abutting position 27222 to the rotating hole 2721, the elastic force of the elastic reset member 260 is less than the pressure of the rotating part 272. The resultant force of the two forces is directed away from the abutting block 243. The resultant force drives the first sliding member 240 to slide relative to the second sliding member 250, thereby making the two in the first connection state, which in turn causes the retaining ring member 230 to expand outward, thereby making the sealing member 220 in the sealing state.

[0112] In some embodiments, the second abutment position 27222 and the handle 271 are located on opposite sides of the rotating hole 2721, and the first abutment position 27221 and the handle 271 are located on adjacent sides of the rotating hole 2721.

[0113] In this way, when the user rotates the handle 271, turning the handle 271 about 90° away from the lid 210 will cause the second abutment position 27222 to abut against the abutment block 243. At this time, the handle 271 is basically in a vertically unfolded state, which is convenient for the user to hold. Turning the handle 271 about 90° towards the lid 210 will cause the first abutment position 27221 to abut against the abutment block 243. The operation is relatively simple and convenient.

[0114] Reference Figure 5As shown, in some embodiments, for ease of processing and assembly, the lid 210 may include a first lid 210a and a second lid 210b, a handle 270 is rotatably connected to the first lid 210a, and a seal 220 and a retaining ring 230 are connected to the second lid 210b.

[0115] In one possible implementation, two seals 220 are spaced apart along the height of the water tank, and the seals 220 and the retaining rings 230 are arranged in a one-to-one correspondence.

[0116] Thus, by setting two sealing elements 220, the sealing performance of the water tank structure can be improved, and each sealing element 220 is provided with a corresponding retaining ring 230 to provide the retaining ring 230 to regulate the state of the sealing element 220, thereby making the sealing performance of the sealing element 220 better, and the tank cover assembly 200 is easier to disassemble and assemble.

[0117] In specific implementation, each retaining ring 230 can be provided with two second sliding members 250. These two second sliding members 250 are arranged at intervals along the circumference of the retaining ring 230 so that the retaining ring 230 can be expanded outward simultaneously by the two second sliding members 250. For example, the two second sliding members 250 can be arranged symmetrically.

[0118] like Figure 6 As shown, the water tank structure includes two sealing elements 220, two retaining rings 230, two first sliding elements 240, and four second sliding elements 250. The retaining rings 230 correspond one-to-one with the sealing elements 220, and each retaining ring 230 is equipped with two second sliding elements 250. The upper and lower two second sliding elements 250 share one first sliding element 240. This effectively allows for the expansion and contraction of the retaining rings 230 and improves the compactness of the water tank structure.
