The sewage generated when cleaning the mop is recycled into the sewage tank. In order to ensure that the cleaning robot can recycle sewage normally during work, the sewage tank needs to be installed correctly and discharged in time. However, the existing sewage tank is relatively cumbersome to disassemble and assemble, and the setting of detection structures such as in-place detection and water full detection makes the structure of the cleaning robot more complicated, further increasing the difficulty of assembling the cleaning robot.

[0048] 1 and 2 , an embodiment of the present application provides a cleaning device, including a base 10 , a walking mechanism (not shown), a cleaning assembly (not shown) and a water tank 20 .

[0049] The base 10 is a shell structure, and the walking mechanism is installed at the bottom of the base 10, which is used to drive the base 10 to move on the ground or other working surfaces. The cleaning component is installed on the base 10, which is used to clean the ground and can perform self-cleaning during the working process. The water tank 20 is detachably installed on the base 10 and is located on one side of the cleaning component, and is used to collect sewage generated by the cleaning component during the self-cleaning process.

[0050] As shown in FIG. 2 and FIG. 3 , further, in order to realize rapid disassembly, assembly and detection of the water tank 20 , the cleaning device also includes a bracket 30 , a button assembly 40 and a detection module 60 , and the water tank 20 is provided with a conductive module 21 matching the detection module 60 .

[0051] Specifically, the bracket 30 is mounted on the base 10 and is located on one side of the water tank 20. The button assembly 40 is mounted on the bracket 30. The button assembly 40 is used to switch the water tank 20 between a locked state fixed relative to the base 10 and an unlocked state that can be separated from the base 10. The detection module 60 is mounted on the bracket 30. When the water tank 20 is in the locked state, the detection module 60 and the conductive module 21 are in contact with each other to be electrically connected.

[0052] In this way, the button assembly 40 and the detection module 60 are integrated on the structure of the bracket 30. On the one hand, the water tank 20 can be disassembled and assembled through the button assembly 40, and on the other hand, the relevant detection of the water tank 20 can be achieved through the detection module 60, which effectively saves the number of parts, simplifies the overall structure of the cleaning equipment, and significantly improves the assembly efficiency of the cleaning equipment.

[0053] Furthermore, in the present application, a certain lifting space is reserved in the base 10 for the cleaning component, and the cleaning component can be lifted up and down as needed, so when the cleaning device encounters a carpet or other object to be cleaned that cannot be wetted by water during the cleaning process, the cleaning component can be lifted upward to prevent the carpet from being wetted. Therefore, in order not to occupy the lifting space of the cleaning component, in the present application, in the forward direction of the cleaning device, the cleaning component is located in front of the water tank 20, and the bracket 30 is located above the water tank 20 in the direction of gravity, so the arrangement of the button component 40 and the detection module 60 will not occupy the lifting space of the cleaning component.

[0054] In the prior art, since the water tank is usually arranged inside the cleaning device, when the operator tries to observe the water level, the water tank is blocked by the top decorative cover and cannot be directly viewed, so the decorative cover must be opened to take out the water tank for observation. In the present application, as a preferred embodiment, the water tank 20 is located at the rear of the base 10, so that the operator can easily observe the water level in the water tank 20.

[0055] In the following embodiments, the direction parallel to the forward direction of the cleaning device is defined as the first direction (i.e., the X direction in FIG. 3 ), the height direction of the cleaning device is defined as the second direction (i.e., the Z direction in FIG. 3 ), and the width direction of the cleaning device is defined as the third direction (i.e., the Y direction in FIG. 4 ). The first direction, the second direction, and the third direction intersect each other. As a preferred embodiment, the first direction, the second direction, and the third direction are perpendicular to each other. In this way, the cleaning assembly is located on one side of the water tank 20 in the first direction, and the bracket 30 is located above the water tank 20 in the second direction.

[0056] As shown in Figures 4 to 6, the water tank 20 is a hollow shell-like structure. The water tank 20 is inserted into the base 10 along the first direction. The water tank 20 is provided with a locking groove 20a and a conductive module 21 on one side close to the bracket 30 in the second direction. The locking groove 20a is used to cooperate with the button assembly 40, and the conductive module 21 is used to be electrically connected to the detection module 60.

[0057] The bracket 30 includes a first mounting portion 32 and two second mounting portions 34. The two second mounting portions 34 are respectively located on opposite sides of the first mounting portion 32 in the third direction. The first mounting portion 32 is used to mount the button assembly 40, and the second mounting portion 34 is used to mount the detection module 60. It can be understood that the structure of the bracket 30 is not limited to this and can be set as needed to meet different requirements.

[0058] The button assembly 40 is mounted on the first mounting portion 32 of the bracket 30, and the button assembly 40 can be switched between the first state and the second state under the action of an external force. When the button assembly 40 is in the first state, the button assembly 40 is inserted into the locking groove 20a of the water tank 20 to put the water tank 20 in a locked state, thereby preventing the water tank 20 from being separated from the base 10 so that the cleaning device can work normally. When the button assembly 40 is in the second state, the button assembly 40 is separated from the locking groove 20a to put the water tank 20 in an unlocked state, thereby facilitating the operator to remove the water tank 20 from the base 10.

[0059] In this way, the water tank 20 can be locked and unlocked simply by changing the state of the button assembly 40, which greatly facilitates the disassembly and assembly of the water tank 20, simplifies the use of the cleaning equipment, effectively improves the user experience of the cleaning equipment, and further reduces people's housework burden.

[0060] Specifically, the button assembly 40 includes a button 41, a latch 43, and a transmission member 45 that are matched with each other. The transmission member 45 is rotatably mounted at the middle position of the first mounting portion 32 of the bracket 30, and the two opposite ends of the transmission member 45 in the third direction are respectively connected to the button 41 and the latch 43. The button 41 is movably mounted on one side of the first mounting portion 32 in the third direction along the second direction, and is limited to one end of the transmission member 45 in the third direction. The latch 43 is movably mounted on the other side of the first mounting portion 32 in the third direction along the second direction, and is limited to the other end of the transmission member 45 in the third direction.

[0061] In this way, the button 41 and the latch 43 are connected by transmission through the transmission member 45. The button 41 can move along the second direction to approach or move away from the water tank 20 under the action of an external force, thereby driving the transmission member 45 to rotate relative to the bracket 30, and finally driving the latch 43 to move along the second direction to insert into or disengage from the locking groove 20a. Specifically, when the operator presses the button 41, the button 41 moves toward the water tank 20 along the second direction, and one end of the transmission member 45 moves toward the water tank 20 under the push of the button 41, and the other end of the transmission member 45 moves in the direction away from the water tank 20 based on the lever principle, thereby driving the latch 43 connected to the end to disengage from the locking groove 20a.

[0062] In some embodiments, the button assembly 40 further includes a first restoring member 47 and a second restoring member 49. The first restoring member 47 is disposed between the bracket 30 and the button 41, and the first restoring member 47 can generate a restorable deformation to apply a force to the button 41 to move it away from the water tank 20 in the second direction. When the operator presses the button 41 downward in the second direction, the first restoring member 47 is compressed under the force applied by the operator, and the button 41 moves in the second direction toward the water tank 20. When the operator releases the button 41, the first restoring member 47 returns to the initial state, and the button 41 moves in the second direction away from the water tank 20 under the push of the first restoring member 47 and returns to the initial position.

[0063] The second reset member 49 is disposed between the bracket 30 and the latch 43. The second reset member 49 can generate a restorable deformation to apply a force to the latch 43 to make it close to the locking groove 20a, so that the latch 43 is inserted into the locking groove 20a of the water tank 20. When the operator presses the button 41 downward along the second direction, the transmission member 45 drives the button 41 to move upward along the second direction and disengage from the locking groove 20a. At this time, the second reset member 49 is in a compressed state. When the operator releases the button 41, the second reset member 49 returns to the initial state, and the latch 43 moves toward the water tank 20 under the push of the second reset member 49.

[0064] In some embodiments, the cleaning device further includes a pushing assembly 50, which is located between the base 10 and the water tank 20, and is used to apply a force along the second direction away from the cleaning assembly to the water tank 20. When the water tank 20 is in an unlocked state, the pushing assembly 50 pushes a portion of the water tank 20 to move along the second direction away from the cleaning assembly to extend out of the base 10, thereby facilitating the operator to take the water tank 20 from the base 10.

[0065] Specifically, in some embodiments, the pushing assembly 50 includes a pushing member 52 and an elastic member 54. One end of the pushing member 52 is movably mounted on the water tank 20 along the second direction, and the other end of the pushing member 52 is abutted against the base 10. One end of the elastic member 54 is limited to the water tank 20, and the other end of the elastic member 54 is limited to the pushing member 52. The elastic member 54 can generate a restorable deformation to apply a force to the water tank 20 to make it partially extend out of the base 10.

[0066] As shown in Figures 2, 3, 4 and 7, the detection module 60 is installed on the second mounting portion 34 of the bracket 30, and includes multiple detection units. The conductive module 21 includes multiple conductive units. The detection units and the conductive units can contact each other to achieve electrical connection, thereby realizing different detection functions.

[0067] Specifically, the detection module 60 includes a first detection unit 61, a second detection unit 63 and a third detection unit 65, wherein the first detection unit 61 and the second detection unit 63 are mounted on a second mounting portion 34 of the bracket 30, and the third detection unit 65 is mounted on another second mounting portion 34. The conductive module 21 includes a first conductive unit 212 and a second conductive unit 214, both of which are mounted on the water tank 20 and pass through the base 10 to contact the detection module 60, and the first conductive unit 212 and the second conductive unit 214 are spaced apart in the third direction.

[0068] When the water tank 20 is in a locked state, the first detection unit 61 and the second detection unit 63 are respectively in contact with and electrically connected to the first conductive unit 212, the second conductive unit 214 is in contact with and electrically connected to the third detection unit 65, and the first detection unit 61, the second detection unit 63 and the first conductive unit 212 together form a conductive circuit, so it can be determined that the water tank 20 has been installed in place to achieve in-situ detection.

[0069] When the water tank 20 is in a locked state and the liquid in the water tank 20 reaches a preset liquid level, the first conductive unit 212 is electrically connected to the second conductive unit 214 through the liquid in the water tank 20, so the first detection unit 61, the second detection unit 63, the first conductive unit 212, the second conductive unit 214 and the third detection unit 65 together form a conductive circuit, thereby determining that the water in the water tank 20 has reached the preset liquid level and realizing full water detection.

[0070] In some embodiments, the cleaning device also includes at least one detection mounting member 70, which is mounted on the bracket 30 from bottom to top along the second direction and can move relative to the bracket 30 along the second direction. The detection module 60 is mounted on the detection mounting member 70 and contacts the conductive module 21 driven by the detection mounting member 70.

[0071] Specifically, the detection mounting member 70 has a roughly cubic shell structure, including a shell bottom wall and a shell side wall extending from the edge of the shell bottom wall toward the second direction, the shell side wall circumferentially surrounds the shell bottom wall to form a accommodating groove with one end open, and the shell bottom wall is provided with a connecting hole allowing the detection unit to pass through, and the shell side walls are respectively provided with clip-on portions that cooperate with the detection unit on opposite sides in the third direction.

[0072] Furthermore, the detection mounting member 70 also includes two limiting portions 72, which are arranged on opposite sides of the detection mounting member 70 in the first direction. The limiting portions 72 are used to abut against the bracket 30 in the direction of moving toward the water tank 20, thereby limiting the position of the detection mounting member 70 in the first direction and preventing the detection mounting member 70 from escaping from the bracket 30 along the first direction.

[0073] Each detection unit includes a detection portion 612 and two elastic arms 614, the two elastic arms 614 are respectively connected to the two side edges of the detection portion 612 in the third direction, and one end of each elastic arm 614 is connected to the detection portion 612, and the other end extends along the second direction, and each elastic arm 614 is provided with a buckle 6141 corresponding to the clamping portion on the detection mounting member 70. In this way, the detection unit is installed in the detection mounting member 70 through the mutual cooperation of the buckle 6141 and the clamping groove, and the detection portion 612 passes through the connecting hole to be electrically connected to the conductive unit.

[0074] Furthermore, the cleaning device also includes a supporting member 80, which is limited between the bracket 30 and the detection mounting member 70. The supporting member 80 can generate a recoverable deformation in the second direction under the action of an external force, so as to apply a force toward the water tank 20 to the detection mounting member 70, so that the detection unit can be in close contact with the conductive unit, thereby ensuring that the two can be stably electrically connected.

[0075] As shown in FIG. 5 and FIG. 6 , the disassembly principle of the water tank 20 is as follows:

[0076] When the water tank 20 is normally installed on the base 10, the button assembly 40 is in the first state, and the latch 43 of the button assembly 40 is inserted into the locking groove 20a of the water tank 20 under the abutment of the second restoring member 49, so that the water tank 20 cannot be separated from the base 10 along the second direction and is in a locked state. At this time, the button 41 of the button assembly 40 is also at a position away from the water tank 20 under the abutment of the first restoring member 47.

[0077] When removing the water tank 20, the operator presses the button 41 of the button assembly 40 downward along the second direction, and the button assembly 40 switches from the first state to the second state. The first reset member 47 is compressed under the pressure and allows the button 41 to move toward the water tank 20, thereby driving the transmission member 45 to rotate, and then driving the pin 43 to move upward along the second direction so that the pin 43 leaves the locking groove 20a of the water tank 20. At this time, the second reset member 49 is in a compressed state.

[0078] After the latch 43 leaves the locking groove 20a, the elastic member 54 of the pushing assembly 50 switches from a compressed state to an extended state, thereby pushing the water tank 20 to move along the second direction away from the cleaning assembly and extend out of the base 10. At this time, the operator can remove the water tank 20 from the base 10.

[0079] When the water tank 20 extends out of the base 10 under the push of the pushing assembly 50 , the force applied by the operator to the button 41 disappears, the first reset member 47 drives the button 41 to return to the initial position, and the latch 43 also returns to the initial position under the drive of the second reset member 49 .

[0080] When installing the water tank 20, the operator inserts the water tank 20 into the base 10 along the first direction, and the latch 43 moves upward along the second direction under the resistance of the water tank 20. When the water tank 20 is completely located in the base 10, the latch 43, which has lost the resistance of the water tank 20, is pushed by the second restoring member 49 and extends into the locking groove 20a of the water tank 20 to re-lock the water tank 20.

[0081] As shown in FIG. 3 and FIG. 4 , the principle of in-situ detection of the water tank 20 of the above cleaning equipment is as follows:

[0082] When the water tank 20 is installed on the base 10 and is in a locked state, the first detection unit 61 and the second detection unit 63 are respectively in contact with and electrically connected to the first conductive unit 212, and the first detection unit 61, the second detection unit 63 and the first conductive unit 212 together form a conductive circuit, thereby judging that the water tank 20 has been installed in place.

[0083] The principle of detecting the full water of the water tank 20 of the above cleaning equipment is as follows:

[0084] When the water tank 20 is installed on the base 10 and is in a locked state, when the liquid in the water tank 20 is lower than the preset liquid level, the first conductive unit 212 and the second conductive unit 214 are in a disconnected state, so the first detection unit 61, the second detection unit 63, the first conductive unit 212, the second conductive unit 214 and the third detection unit 65 cannot form a complete conductive circuit.

[0085] When the liquid in the water tank 20 continues to accumulate and reaches a preset liquid level, the first conductive unit 212 is electrically connected to the second conductive unit 214 through the liquid in the water tank 20. Therefore, the first detection unit 61, the second detection unit 63, the first conductive unit 212, the second conductive unit 214 and the third detection unit 65 together form a conductive circuit, thereby determining that the water in the water tank 20 has reached the preset liquid level.

[0086] In the above cleaning device, since the bracket 30 integrates the button assembly 40 and the detection module 60, modular assembly of the button assembly 40 and the detection module 60 is achieved, which effectively improves the production and assembly efficiency and simplifies the overall structure of the cleaning device.

[0087] The technical features of the above-described embodiments may be arbitrarily combined.
