Description

Technical Field

[0001] This application relates to the field of cleaning equipment, and more particularly to a cleaning device and its water tank assembly. Background Technology

[0002] Currently, cleaning robots equipped with cleaning equipment have both automatic and manual water filling ports for their water tanks. Automatic water filling ports are typically located in pre-drilled holes on the exterior of the machine, which disrupts the overall aesthetics of the design. Manual water filling ports, on the other hand, are located under the tank's cover, requiring the cover to be opened for manual water filling. This is inconvenient and poses a safety hazard as it may cause liquid to leak into the machine's interior during the filling process. Summary of the Invention

[0003] This application provides a cleaning device and its water tank and water container to solve the above-mentioned problems.

[0004] This application provides a cleaning device, including a body and a water tank. The water tank includes a housing and a water container. The housing is mounted on the body and has a water storage space inside. The water container includes a box and a water valve. The box is movably mounted on the housing and has a first water inlet, a second water inlet, and an outlet connected together, with the outlet communicating with the water storage space. The water valve is mounted on the box and can move relative to the box to close or open the first water inlet. The water container has a first usage state and a second usage state. In the first usage state, the box is retracted into the housing, and the water valve protrudes from the surface of the housing. In the second usage state, the box extends out of the housing, exposing the second water inlet.

[0005] In some embodiments of this application, the water gate includes a door panel and a reset element. The reset element is connected between the door panel and the housing and can be compressed by the door panel under external force, and can push against the door panel to close the first water inlet after the external force is released.

[0006] In some embodiments of this application, the water gate further includes a door frame and a pivot. The door frame surrounds the first water inlet, the pivot is disposed on one side of the door frame, the door panel is pivotally connected to the pivot, the reset element is sleeved on the pivot, and the first end of the reset element pushes against the door panel and the second end pushes against the housing.

[0007] In some embodiments of this application, a limiting groove is provided on the door panel, and a stop is provided on the side of the box body adjacent to the door frame. The first end is engaged in the limiting groove, and the second end is located in the gap between the stop and the door frame.

[0008] In some embodiments of this application, a fastener is provided on one side of the door panel, the fastener being engaged with the pivot and rotatable relative to the pivot.

[0009] In some embodiments of this application, the housing includes a top surface and a bottom surface opposite to each other. A clearance groove is provided on the side of the bottom surface adjacent to the first water inlet. The reset element is disposed in the clearance groove and pushes the door panel against the top surface.

[0010] In some embodiments of this application, a groove is provided on the side of the box body adjacent to the first water inlet. The groove is provided along the top surface toward the bottom surface and communicates with the clearance groove. A handle is provided on the door panel. The handle extends out of the box body through the groove and can be displaced along the groove.

[0011] In some embodiments of this application, the surface of the box is provided with an installation port communicating with the water storage space, and the water box further includes a sleeve, which is engaged in the installation port and sleeved on the outside of the box, wherein the sleeve is fixed to the box and the box can move back and forth relative to the sleeve.

[0012] In some embodiments of this application, a sliding track mechanism is provided between the sleeve and the housing, the sliding mechanism being arranged along the axial direction of the sleeve to guide the displacement of the housing relative to the sleeve.

[0013] In some embodiments of this application, a guide rail and a limiting member are provided between the sleeve and the box body. The guide rail is arranged along the axial direction of the sleeve and has a closed end on the side facing the first water inlet. The limiting member extends into the guide rail and can abut against the closed end after being displaced a predetermined distance along the guide rail.

[0014] In some embodiments of this application, a stop portion is provided on the side of the sleeve facing the second water inlet. The stop portion extends into the second water inlet in the first state and corresponds to the side edge of the box body located inside the second water inlet, so as to prevent the box body from displacing in the direction of the water storage space.

[0015] In some embodiments of this application, the diameter of the first inlet is larger than the diameter of the outlet, the housing has an inclined structure between the two, the second inlet is opened on the inclined structure, and the side of the inclined structure facing the first inlet contacts the stop portion, and the side facing the outlet has a gap with the sleeve.

[0016] This application embodiment also provides a cleaning device, including a body and a water tank. The water tank includes a tank body and a water container. The water container includes a box body and a water inlet. The box body is movably disposed on the tank body and has a first water inlet and a second water inlet that are connected to each other. The water inlet is disposed on the box body and can move relative to the box body to close or open the first water inlet. The water container has a first usage state and a second usage state. In the first usage state, the box body is retracted into the tank body, and the water inlet is exposed on the surface of the tank body. In the second usage state, the box body extends out of the tank body, and the second water inlet is exposed.

[0017] This application embodiment also provides a water tank, including: a tank body and a water-holding box. The tank body has a water storage space. The water-holding box includes a box body and a water valve. The box body is movably disposed on the tank body and has a first water inlet, a second water inlet, and a water outlet connected in communication, and the water outlet is connected to the water storage space. The water valve is disposed on the box body and can move relative to the box body to close or open the first water inlet. The water-holding box has a first usage state and a second usage state. In the first usage state, the box body is retracted into the tank body, and the water valve is exposed on the surface of the tank body. In the second usage state, the box body extends out of the tank body, and the second water inlet is exposed.

[0018] This application also provides a water container, including a container body and a water gate. The container body has a first water inlet, a second water inlet, and a water outlet that are connected to each other. The second water inlet is located at the top of the container body, and the first water inlet and the water outlet are located on opposite sides of the container body. The water gate is located on the side of the container body adjacent to the first water inlet, and can move relative to the container body to close or open the first water inlet.

[0019] In this embodiment, the water container is movably mounted on the water tank, and has a first water inlet, a second water inlet, and a water gate that can open and close the first water inlet. Therefore, when the water container is retracted into the tank, applying force to the water gate causes its door panel to move relative to the first water inlet, opening the first water inlet for automatic water filling. After the force is released, the door panel automatically closes the first water inlet, maintaining the integrity of the water container's appearance. Furthermore, when the water container extends out of the tank, the second water inlet opens, allowing for manual water filling. In this case, the water gate remains closed over the first water inlet, preventing liquid from flowing out of the first water inlet onto the cleaning equipment during operation, eliminating safety hazards and improving the user experience.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0032] like Figures 1 to 3 As shown, this application provides a cleaning device, including a body and a water tank 1. The cleaning device can be, but is not limited to, an automated cleaning device with a base station and a self-moving robot, and the water tank 1 is installed on the base station and / or the self-moving robot. Therefore, in this application, the body of the cleaning device can be a base station or a self-moving robot. For ease of explanation, the following embodiments of this application use a self-moving robot as an example of the body, but are not limited thereto.

[0033] The water tank 1 includes a tank body 10 and a water container 20. The tank body 10 is mounted on the machine body, and a water storage space 10a is provided inside the tank body 10. An installation port 10b is provided on the surface of the tank body 10 to connect the water storage space 10a with the external environment, so as to accommodate the water container 20. Liquids such as clean water or cleaning agents can be injected into the water storage space 10a through the water container 20 to supply the self-propelled robot for cleaning.

[0034] Please refer to Figures 1 to 7 The water container 20 includes a sleeve 210, a container body 220, and a water valve 230. The sleeve 210 engages within the mounting opening 10b and is fitted over the container body 220. The sleeve 210 can be fixed to the container body 10 by screws or bolts, allowing the container body 210 to move within the sleeve 210 relative to the container body 10, extending out of the sleeve 210 or moving towards the water storage space 10a and retracting into the container body 10. In some embodiments of this application, a sliding mechanism 240 is also provided between the sleeve 210 and the container body 220. This sliding mechanism 240 extends axially along the sleeve 210 to guide the container body 220 to move stably back and forth relative to the sleeve 210, and to prevent the container body 220 from rotating relative to the sleeve 210 during displacement.

[0035] The sliding mechanism 240 includes a sliding track 241 and a groove 242, one of which is disposed on the inner wall surface of the sleeve 210, and the other is disposed on the outer surface of the housing 220 (e.g., Figure 4 and Figure 5(As shown). For example, in this embodiment, the groove 242 is provided on the outer surface of the box 220, and the sliding track 241 is provided on the inner wall surface of the sleeve 210 and embedded in the groove 242, so that the box 220 can slide along the axial direction of the sleeve 210 under the guidance of the sliding track 241.

[0036] In addition, in some embodiments of this application, a guide rail 250 and a limiting member 260 (e.g., ...) may be provided between the sleeve 210 and the housing 220. Figures 4 to 7 (As shown). The guide rail 250 is arranged on the sleeve 210 along the axial direction of the sleeve 210 and penetrates the wall of the sleeve 210. A closed end 251 is formed on the side of the sleeve 210 corresponding to the mounting port 10b, and an open end 252 connected to the water storage space 10a is formed on the side corresponding to the water storage space 10a.

[0037] The limiting member 260 is disposed on the side of the housing 220 corresponding to the water storage space 10a and protrudes from the outer surface of the housing 220. Simultaneously, when the housing 220 is displaced relative to the sleeve 210, the limiting member 260 can enter the guide rail 250 from the open end 252 and move along the guide rail 250 to the closed end 251. At this time, because the limiting member 260 protrudes from the outer surface of the housing 220, it simultaneously extends radially into the guide rail 250 along the sleeve 210 and can exit from the outer wall of the sleeve 210. Therefore, when the limiting member 260 moves a predetermined distance along the guide rail 250, the limiting member 260 will abut against the closed end 251 of the guide rail 250 and prevent the box 220 from continuing to move out of the box 10, thus preventing the box 220 from detaching from the sleeve 210 and falling out of the box 10.

[0038] It is understood that in some embodiments of this application, one or both of the combination of the guide rail 250 and the limiting member 260 and the sliding mechanism 240 may be provided. Furthermore, in other embodiments of this application, the combination of the guide rail 250 and the limiting member 260 and the sliding mechanism 240 may also be provided between the inner wall surface of the housing 10 near the mounting port 10b and the box body 220, while the sleeve 210 is omitted from the water container 20.

[0039] In this embodiment, the housing 220 is further provided with a first water inlet 220a, a second water inlet 220b, and a water outlet 220c. The first water inlet 220a and the water outlet 220c are respectively located on the sides of the housing 220, for example, on opposite sides of the housing 220, so that the first water inlet 220a can communicate with the external environment of the housing 10, and the water outlet 220c can communicate with the water storage space 10a inside the housing 10. The second water inlet 220b is located at the top of the housing 220 and is located between the first water inlet 220a and the water outlet 220c.

[0040] Similar to the limiting member 260 in the aforementioned embodiments, in some embodiments of this application, a stop portion 211 is provided on the side of the sleeve 210 facing the second water inlet 220b. This stop portion 211 protrudes from the inner wall of the sleeve 210 and extends into the second water inlet 220b near the first water inlet 220a, corresponding to the side edge of the box 220 located within the second water inlet 220b. Therefore, when the box 220 displaces towards the water storage space 10a and retracts into the housing 10, the side edge 221 of the box 220 within the second water inlet 220b can be, but is not limited to, the stop portion 211 that just abuts against the inner wall of the sleeve 210. This limits the distance the box 220 displaces towards the water storage space 10b, preventing the box 220 from detaching from the sleeve 210 and falling into the water storage space 10a.

[0041] Furthermore, in some embodiments of this application, the diameter of the first inlet 220a of the housing 220 is larger than the diameter of the outlet 220c, causing the top of the housing 220 to form an inclined structure 221 between the first inlet 220a and the outlet 220c due to the change in radial dimension. The second inlet 220b is formed on the inclined structure 221, wherein the side of the inclined structure 221 facing the first inlet 220a is the first side edge 222 of the housing 220 within the second inlet 220b, and the side of the inclined structure 221 facing the outlet 220c is the other side edge 223 of the housing 220 within the second inlet 220b (e.g., ...). Figure 3 (As shown). Therefore, the first side edge 222 can contact the stop portion 211 of the sleeve 210, and the second side edge 223 has a gap with the sleeve 210 to avoid the stop portion 211. In this way, when the box body 220 is closed inside the housing 10, the first side edge 222 can abut against the stop portion 211 of the sleeve 210, and when the box body 220 extends outward from the housing 10, the second side edge 223 can be prevented from contacting the stop portion 211 and interfering with the displacement stroke of the box body 220, so that the stroke of the box body 220 moving outward from the housing 10 is not limited by the diameter of the second inlet 220b.

[0042] Please refer to Figures 1 to 5The water gate 230 of the water container 20 is movably mounted on the container body 220 and can move relative to the container body 220 to close or open the first water inlet 220a. In this embodiment, the water gate 230 includes a door panel 231 and a reset element 232. The reset element 232 is connected between the door panel 231 and the container body 220, and normally pushes the door panel 231 to close the first water inlet 220a. When the door panel 231 is opened by an external force, it can be compressed by the door panel 231 to provide displacement stroke for the door panel 231, and after the external force is released, it provides a restoring force for the door panel 231 to return to the state of closing the first water inlet 220a.

[0043] Specifically, in one embodiment of this application, the water gate 230, in addition to the door panel 231 and the reset element 232, also includes a door frame 233 and a rotating shaft 234. The door frame 233 is disposed on the side of the housing 220 where the first water inlet 220a is provided, and surrounds the first water inlet 220a. The rotating shaft 234 is disposed on one side of the door frame 233, for example, on the side inside the housing 220. The door panel 231 is rotatably disposed on the rotating shaft 234, and the reset element 232 may be, but is not limited to, being sleeved on the rotating shaft 234 in the form of a torsion spring, and the first end 2321 and the second end 2322 of the reset element 232 respectively abut against the door panel 231 and the housing 220.

[0044] For example, a latching element 235 is provided on one side of the door panel 231. The structure of the latching element 235 matches the structure of the rotating shaft 234, allowing the door panel 231 to be fastened to the rotating shaft 234 via the latching element 235. It can also rotate relative to the rotating shaft 234 to cover the door frame 233, thus closing the first water inlet 220a, or moving away from the door frame 233 to open the first water inlet 220a. The diameter of the two opposite ends of the rotating shaft 234 can also be set to be larger than the diameter of the latching element 235 on the rotating shaft 234, ensuring that the latching element 235 will not detach from the two opposite ends of the rotating shaft 234 when rotating around it.

[0045] Regarding the configuration of the reset element 232, a limiting groove 231a can be provided on the side of the door panel 231 facing the pivot 234, and a stop block 224 can be provided on the side of the housing 220 adjacent to the door frame 233. This allows the first end 2321 of the reset element 232 to engage in the limiting groove 231a, and the second end 2322 to be fixed in the gap between the stop block 224 and the door frame 233. Therefore, the first end 2321 and the second end 2322 of the reset element 232 can be pushed against the door panel 231 under the action of elastic force, so that the door panel 231 normally closes the first water inlet 220a. In some embodiments of this application, the side of the door panel 231 is further provided with a stepped structure 2312 recessed into the surface of its body 2311. When the door panel 231 closes the first water inlet 220a through its body 2311, this stepped structure 2312 is pressed against the door frame 231 by the elastic force of the reset element 232, so that the door panel 231 is tightly attached to the door frame 233. In addition to preventing the door panel 231 from flipping outward, it can also improve the airtightness of the door panel 231 to the first water inlet 220a and maintain the flatness of the appearance of the water door 230.

[0046] It is worth noting that, since the body 220 of the water container 20 can move relative to the housing 10 within the sleeve 210 and extend out of the housing 10 or be retracted inside the housing 10, the water tank 1 provided in this application embodiment has a first usage state in which the body 220 of the water container 20 is retracted inside the housing 10 and a second usage state in which it extends out of the housing 10.

[0047] In one application scenario of this application embodiment, a water tank 1 is installed on a self-moving robot of a cleaning device, and a water replenishment device is installed on a base station that cooperates with the self-moving robot. The water container 20 of the water tank 1 is normally maintained in a first usage state where the container 220 is retracted into the housing 10. When the self-moving robot returns to the base station and docks, the base station determines that the water tank 1 needs to be replenished. At this time, the water supply pipe on the base station extends towards the water tank 1 and pushes against the door plate 231 of the water gate 230, causing the door plate 231 to flip inward into the housing 220 under the action of external force and compress the reset element 232, thereby opening the first water inlet 220a, so that the water supply pipe T can extend into the housing 10 to fill the water storage space 10a. After the water filling process is completed, when the water filling pipe is withdrawn from the box 220, the door panel 231 is pushed against the door frame 233 by the elastic restoring force of the reset element 232, thereby sealing the first water inlet 220a, ensuring the integrity of the appearance of the water tank 1, and preventing liquid from flowing out from the first water inlet 220a.

[0048] Furthermore, in the second usage state, the user can push the door panel 231 with their finger, causing the door panel 2321 to compress the reset element 232 and flip over, allowing the finger to be inserted into the housing 220 through the first water inlet 220a. The user can then grasp the top of the housing 220 and pull it away from the water tank 1. At this time, water can be manually added to the second water inlet 220b directly above the housing 220. Because the door panel 231 is pressed against the door frame 233 by the reset element 232 and the internal water pressure of the housing 10, it acts as a seal, preventing liquid from flowing out of the first water inlet 220a.

[0049] Furthermore, during the above process, when the box 220 is pulled out of the housing 10 by a predetermined distance, the limiting member 260 on the box 220 abuts against the closed end 251 of the guide rail 250 on the sleeve 210, which can prevent the box 220 from detaching from the housing 10; and when the box 220 is retracted into the housing 10, the first side edge 222 above the box 220 is blocked by the stop part 211 on the sleeve 210, which can prevent the box 220 from falling into the water storage space 10a of the housing 10.

[0050] Based on the above, the water tank 1 provided in this embodiment can meet the water filling needs of both automatic and manual modes. A resettable door panel structure is adopted at the first water inlet 220a, ensuring the water tank and the self-moving robot with the water tank have no holes on their exterior surfaces, thus guaranteeing the integrity of the appearance. When manually adding water, the tank can be pulled away from the machine body without opening the water tank's cover, and there is no risk of water leakage into the self-moving robot's body.

[0051] Please refer to Figure 8 and Figure 9Another embodiment of the cleaning device E provided in this application has a water tank that is structurally similar to the above embodiment. The difference lies in that the water gate 230 of the water tank 20 includes a gate plate 231 and a reset element 232, and a clearance groove 225 is provided inside the box body 220 to accommodate the reset element 232. The box body 220 includes a top surface 226 and a bottom surface 227 facing each other. The second water inlet 220b is located on the top surface 226, and the clearance groove 225 is located on the bottom surface 227, adjacent to the side of the first water inlet 220a. The reset element 232 is located in the clearance groove 225 and can be, but is not limited to, a compression spring. One end of the reset element 232 is fixed to the bottom surface 227 of the box body 220, and the other end is connected to the gate plate 231, pushing the gate plate 231 against the top surface 226 of the box body 220, so that the gate plate 231 normally closes the first water inlet 220a. Furthermore, a guide surface 2313 is provided on the side of the door panel 231 facing outward from the housing 220. This guide surface 2313 is inclined from the side adjacent to the first water inlet 220a toward the second water inlet 220b, so that the horizontal force applied to the guide surface 2313 can be converted into a vertical force, causing the door panel 231 to compress the reset element 232 and open the first water inlet 220a.

[0052] Therefore, in one application scenario of this embodiment, when the self-moving robot equipped with a water tank returns to the base station, the sensors on the base station detect that the self-moving robot has stopped in place and transmit a signal to the control unit, causing the control unit to drive the water supply pipe T on the base station to extend towards the water tank. The head of the water supply pipe T used to push against the door panel 231 can be, but is not limited to, an arc surface or a guide slope that cooperates with the guide surface 2313. When the head of the water supply pipe T applies external force to the guide surface 2313 of the door panel 231, the door panel 231 is subjected to the force transmission and moves towards the relief groove 225 of the housing 220, compressing the reset element 232. At this time, the first water inlet 220a of the housing 220 is opened, allowing the water supply pipe T to continuously extend into the housing to fill the water storage space. When the water filling process is completed, the water filling pipe T exits from the box 220. At this time, due to the elimination of the force applied to the door panel 231, the door panel 231 returns to the starting position under the action of the elastic restoring force of the reset element 232, thus closing the first water inlet 220a.

[0053] Similarly, in the water tank provided in this embodiment, the water container 20, in addition to the first usage state where the container 220 is retracted into the tank, also has a second usage state where the container 220 is pulled out of the tank. In the second usage state, the user can push the door panel 231 with their finger, causing the door panel 2321 to compress the reset element 232, allowing the finger to enter the container 220 through the first water inlet 220a, and the fingertip or fingertip can press against the top surface 226 inside the container 220 or the top of the door panel 231. Then, after applying force to pull the container 220 out of the tank, the finger is removed from the container 220. In this state, the container 220 extends out of the tank to a predetermined distance, and the first water inlet 220a on the container 220 is closed by the door panel 231, with only the second water inlet 220b exposed on the top surface 226 of the container 220. At this point, the user can inject clean water or cleaning fluid through the second inlet 220b, allowing the liquid to flow into the water storage space of the tank through the outlet 220c of the casing 220. After completing the water filling process, push the casing 220 back into the tank, so that the second inlet 220b is submerged in the tank, with only the water gate 230 exposed on the surface of the tank to maintain the uniformity of the water tank's appearance.

[0054] Continuing from the above, in some embodiments of this application, a groove 228 is also provided on the side of the housing 220 adjacent to the first water inlet 220a. This groove 228 is provided along the direction from the top surface 226 of the housing 220 toward the bottom surface 227 and communicates with the clearance groove 225.
