[0027] See also Figure 1 , Figure 1 A schematic diagram of the structure of a cleaning device 100 in an embodiment of the present application is shown. A cleaning device 100 provided in an embodiment of the present application, referring to Figure 2 and Figure 4 , Figure 2 and Figure 4 Two usage states of the cleaning device 100 are shown. In the present application, the cleaning device 100 is described as a floor scrubber as an example.

[0028] like Figure 1As shown, the cleaning device 100 includes a main body 110 and an adjustment assembly 120. The main body 110 includes a sewage tank 111. The sewage tank 111 is used to store the sucked sewage and the garbage that enters with the sewage. The sewage tank 111 includes a side wall 1111 and a bottom surface 1112. The bottom surface is provided with a sewage outlet. The side wall 1111 and the bottom surface 1112 together enclose a storage space for storing sewage and garbage. Figure 1 As shown, when the cleaning device 100 is in a horizontal state and there is no need to recycle garbage, for example, the cleaning device 100 performs normal floor cleaning, at this time, the bottom surface 1112 of the sewage tank 111 is horizontal, and the sewage tank 111 can store water normally.

[0029] like Figure 1 As shown, Figure 1 The cleaning device 100 is in an initial state, and the adjustment component 120 has not yet acted on the main body 110. Figure 2 and Figure 3 As shown, Figure 2 and Figure 3 The adjusting component 120 acts on the sewage tank 111, and the adjusting component 120 is configured to drive the bottom surface 1112 of the sewage tank 111 to tilt toward the sewage outlet. On the one hand, it can increase the speed of sewage in the sewage tank 111 flowing out of the sewage tank 111, thereby increasing the possibility of carrying garbage out. On the other hand, it can make the garbage with higher density and larger mass (such as stones, etc.) located under the inclined bottom surface 1112, so that it slides out of the sewage tank 111 under the action of gravity, so as to facilitate the base station to recycle garbage. It can be understood that the purpose of the adjusting component 120 driving the bottom surface 1112 to tilt is to enable the garbage in the sewage tank 111 to automatically flow to the sewage outlet of the sewage tank 111. Therefore, when the adjusting component 120 drives the bottom surface 1112 to tilt, the position of the bottom surface 1112 close to the sewage outlet is the lower position of the bottom surface 1112.

[0030] like Figure 2 and Figure 3 As shown, in one embodiment, the side wall 1111 and the bottom surface 1112 are intersected and connected to each other, and one end of the side wall 1111 connected to the bottom surface 1112 is a flexible section 1113 made of flexible material. The flexible section 1113 can bend when it is squeezed by force, so that the bottom surface 1112 can be tilted relative to the side wall 1111 without affecting the side wall 1111 and other parts of the main body 110.

[0031] In other embodiments, the side wall 1111 may be made entirely of rigid materials, and in this case, the connection between the sewage tank 111 and other components may be made of flexible materials, and when the driving member 121 drives the bottom surface 1112 to tilt, the sewage tank 111 as a whole tilts along with the bottom surface 1112. Alternatively, in other embodiments, the side wall 1111 and the connection between the sewage tank 111 and other components may be made of rigid materials, and when the driving member 121 drives the bottom surface 1112 to tilt, the main body 110 tilts along with the bottom surface 1112.

[0032] In one embodiment, the flexible material is elastic, and the flexible section 1113 has a tendency to drive the bottom surface 1112 to return to the horizontal position, so that when the bottom surface 1112 is not affected by the adjustment component 120, the bottom surface 1112 can return to the horizontal position under the action of its own gravity and the elastic force of the flexible section 1113. Figure 1 The bottom surface 1112 is reset to a horizontal state.

[0033] In other embodiments, the flexible section 1113 may also be made of a non-elastic flexible material, such as a waterproof cloth, etc. In this case, when the bottom surface 1112 is not affected by the adjustment component 120, the bottom surface 1112 is reset to the position under the action of its own gravity. Figure 1 The bottom surface 1112 is reset to a horizontal state.

[0034] like Figures 1 to 3 As shown, in one embodiment, the adjustment component 120 includes a driving member 121 and a connecting rod 122 fixedly connected to the bottom surface 1112, and the driving member 121 is configured to drive the connecting rod 122 to move upward to drive the bottom surface 1112 to tilt. In some embodiments, the driving member 121 can be a stepping motor, a telescopic cylinder, etc., which can drive the connecting rod 122 to move upward. It can be understood that the connecting rod 122 is connected to the position of the bottom surface 1112 away from the sewage outlet, so that when the adjustment component 120 drives the bottom surface 1112 to tilt, the position of the bottom surface 1112 away from the sewage outlet is raised, so that the position of the bottom surface 1112 close to the sewage outlet is the lower position of the bottom surface 1112, and then the heavier garbage originally gathered on the bottom surface 1112 of the sewage tank 111 will automatically flow to the sewage outlet of the sewage tank 111 under the influence of its own gravity, so as to facilitate the base station to recycle garbage.

[0035] like Figure 3 As shown, in the embodiment provided in the present application, the adjustment assembly 120 also includes a first transmission member 123 fixedly connected to the driving member 121, and the driving member 121 is configured to drive the first transmission member 123 to rotate. The first transmission member 123 is located below the connecting rod 122 and the connecting rod 122 is located on the rotation path of the first transmission member 123.

[0036] like Figure 2 and Figure 3As shown, in the present embodiment, the driving member 121 can drive the first transmission member 123 to rotate counterclockwise. At this time, the first transmission member 123 pushes the connecting rod 122 to drive the connecting rod 122 to move upward. The bottom surface 1112 fixedly connected to the connecting rod 122 is tilted by the upward traction force of the connecting rod 122, thereby driving the garbage in the sewage tank 111 to be discharged.

[0037] When the cleaning device 100 completes indoor cleaning and returns to the base station for garbage collection, Figure 2 and Figure 3 As shown, the driving member 121 drives the first transmission member 123 to rotate (in this embodiment, the driving member 121 drives the first transmission member 123 to rotate counterclockwise), so as to drive the connecting rod 122 to move upward through the first transmission member 123, thereby driving the bottom surface 1112 fixedly connected to the connecting rod 122 to tilt. At this time, the heavier garbage originally gathered on the bottom surface 1112 of the sewage tank 111 will automatically flow to the sewage outlet of the sewage tank 111 under the influence of its own gravity, thereby facilitating the garbage collection of the base station. When the garbage collection is completed, the driving member 121 is reset. At this time, the bottom surface 1112 of the sewage tank 111 is reset to the bottom surface 1112 of the sewage tank 111 under the action of its own gravity and the elastic force of the flexible section 1113. Figure 1 The status shown is for the next recycling and separation work.

[0038] like Figure 1 and Figure 4 As shown, in one embodiment, the main body 110 further includes an air outlet channel 112 connected to the sewage tank 111. Figure 1 As shown, the air outlet channel 112 is located above the sewage tank 111 and communicates with the interior of the sewage tank 111. When the main body 110 is turned over, the sewage in the sewage tank 111 may enter the air outlet channel 112. The adjustment component 120 is also configured to block the air outlet channel 112 to prevent the sewage in the sewage tank 111 from flowing along the air outlet channel 112 and contaminating the filter element when the main body 110 is turned over.

[0039] like Figure 1 and Figure 4 As shown, in one embodiment, the adjustment component 120 includes a driving member 121 and a water blocking member 124. The water blocking member 124 is movably disposed in the air outlet channel 112. The water blocking member 124 can rotate or move relative to the air outlet channel 112. In the present application, the water blocking member 124 can rotate in the air outlet channel 112. In other embodiments, the water blocking member 124 can also be able to move in the air outlet channel 112 to block the air outlet channel 112.

[0040] Combination Figure 1 and Figure 4 The driving member 121 is configured to drive the water blocking member 124 to switch between the first state and the second state. Figure 4As shown, when the water blocking member 124 is in the first state, the water blocking member 124 blocks the air outlet channel 112. Figure 1 As shown, when the water blocking member 124 is in the second state, the air outlet channel 112 is unobstructed.

[0041] like Figure 4 As shown, in one embodiment, the adjustment assembly 120 also includes a second transmission member 125 fixedly connected to the driving member 121, the driving member 121 is configured to be able to drive the second transmission member 125 to move up and down, and the second transmission member 125 is located below the water blocking member 124, the water blocking member 124 is on the upward moving path of the second transmission member 125, the second transmission member 125 moves upward to abut against the water blocking member 124 and drive the water blocking member 124 to switch from the second state to the first state.

[0042] like Figure 1 As shown, in the embodiment provided in the present application, the second transmission member 125 is connected to one end of the first transmission member 123 away from the connecting rod 122, and the driving member 121 is located between the second transmission member 125 and the connecting rod 122, so when the driving member 121 drives the first transmission member 123 to rotate, when the end of the first transmission member 123 close to the connecting rod 122 moves upward, the second transmission rod moves downward and away from the water blocking member 124, and when the first transmission member 123 drives the second transmission rod to move upward and abuts against the water blocking member 124, the end of the first transmission member 123 close to the connecting rod 122 moves downward and away from the connecting rod 122. That is, in the present embodiment, the adjustment component 120 drives the bottom surface 1112 of the sewage tank 111 to tilt and drives the water blocking member 124 to block the air outlet channel 112 without interfering with each other and can be realized only one by one.

[0043] Moreover, in this embodiment, the adjustment component 120 drives the bottom surface 1112 of the sewage tank 111 to tilt and drives the water blocking member 124 to block the air outlet channel 112, which are all controlled by the same driving member 121. When the driving member 121 drives the first transmission member 123 to rotate clockwise, the first transmission member 123 moves upward to drive the connecting rod 122 connected to the bottom surface 1112 to move upward, thereby driving the bottom surface 1112 of the sewage tank 111 to tilt; when the driving member 121 drives the first transmission member 123 to rotate counterclockwise, the first transmission member 123 drives the second transmission member 125 to move upward, so that the second transmission member 125 abuts against the water blocking member 124 and drives the water blocking member 124 to switch from the second state to the first state, thereby blocking the air outlet channel 112 through the water blocking member 124.

[0044] like Figure 4As shown, in one embodiment, the water blocking member 124 includes a water blocking portion 1241 located inside the water blocking channel, the water blocking portion 1241 is a plate-shaped structure and is rotatably connected to the wall of the air outlet channel 112, and the second transmission member 125 can drive the water blocking member 124 to rotate when moving upward to block the air outlet channel 112. It can be understood that the width of the water blocking plate needs to be greater than the vertical width of the air outlet channel 112, and the length of the water blocking plate is slightly smaller than the length of the air outlet channel 112 so that the water blocking plate can block the water blocking channel.

[0045] like Figure 1 As shown, the water blocking portion 1241 is rotatably connected to the wall of the air outlet channel 112, the water blocking portion 1241 is provided with a rotating shaft, and the wall of the air outlet channel 112 is provided with a hole adapted to the rotating shaft. Preferably, the rotating shaft and the hole are sealed and matched.

[0046] like Figure 4 As shown, in one embodiment, the water blocking member 124 further includes a connecting section 1242 and an abutting portion 1243 located outside the water blocking channel, wherein the connecting section 1242 penetrates the wall of the air outlet channel 112 and acts as a rotating shaft, and the second transmission member 125 abuts against the abutting portion 1243 when moving upward, as shown in FIG. Figure 4 As shown, in this embodiment, the second transmission member 125 abuts against the side of the abutting portion 1243 close to the rotation axis, but the movement trajectory of the second transmission member 125 does not intersect with the rotation axis. The abutting portion 1243 is provided with a counterweight block 1244, which has the tendency to drive the water blocking member 124 to rotate to switch from the first state to the second state. When the cleaning device 100 is reset to a normal position, the driving member 121 drives the first transmission member 123 to reset to Figure 1 state, so that the water blocking member 124 can be reset to the second state under the action of the counterweight block 1244 and its own gravity when it is not affected by the driving member 121, and the air outlet channel 112 is in a smooth state. Figure 4 As shown, in this embodiment, the counterweight block 1244 is located on the side of the abutment portion 1243 away from the rotation axis, that is, the counterweight block 1244 is farther away from the rotation axis than the position where the abutment portion 1243 abuts against the second transmission member 125, so as to increase the torque of the counterweight block 1244, thereby reducing the difficulty of resetting through the counterweight block 1244, and at the same time reducing the mass requirement of the counterweight block 1244.

[0047] The cleaning device 100 provided by the above solution can be used in the following three situations:

[0048] The first type: when the cleaning device 100 is in a horizontal state and there is no need to recycle garbage, for example, the cleaning device 100 performs normal floor cleaning, at this time, the adjustment component 120 is in a state such as Figure 1In the state shown in FIG. 1 , the bottom surface 1112 of the sewage tank 111 is horizontal, the sewage tank 111 can store water normally, and the water blocking member 124 is in a state as shown in FIG. 1 under the action of gravity. Figure 1 In the first state (ie, the horizontal state) shown, the air outlet channel 112 is in an unobstructed state.

[0049] The second type: when the cleaning device 100 completes indoor cleaning and returns to the base station for garbage collection, such as Figure 2 and Figure 3 As shown, the driving member 121 drives the first transmission member 123 to rotate (in this embodiment, the driving member 121 drives the first transmission member 123 to rotate counterclockwise), so as to drive the connecting rod 122 to move upward through the first transmission member 123, thereby driving the bottom surface 1112 fixedly connected to the connecting rod 122 to tilt. At this time, the heavier garbage originally gathered on the bottom surface 1112 of the sewage tank 111 will automatically flow to the sewage outlet of the sewage tank 111 under the influence of its own gravity, thereby facilitating the garbage collection of the base station. When the garbage collection is completed, the driving member 121 is reset. At this time, the bottom surface 1112 of the sewage tank 111 is reset to the bottom surface 1112 of the sewage tank 111 under the action of its own gravity and the elastic force of the flexible section 1113. Figure 1 The status shown is for the next recycling and separation work.

[0050] The third method: when the cleaning device 100 is turned over, the adjustment component 120 is as follows: Figure 4 As shown, at this time, the driving member 121 drives the second transmission member 125 to move upward through the first transmission member 123. In this embodiment, the driving member 121 drives the first transmission member 123 to rotate counterclockwise to abut against the water blocking member 124 and drive the water blocking member 124 to rotate to the first state, so that the air outlet channel 112 is blocked by the water blocking member 124. When the cleaning device 100 is reset to a normal position, the driving member 121 drives the first transmission member 123 to reset to Figure 1 At this time, the water blocking member 124 is reset to the position as shown in FIG. Figure 1 state, the air outlet channel 112 is in an unobstructed state.

[0051] The cleaning device 100 provided in the above scheme is provided with an adjustment component 120 that can drive the bottom surface 1112 of the sewage tank 111 to tilt, so that when the cleaning device 100 completes indoor cleaning and goes to the base station for garbage collection, the adjustment component 120 drives the bottom surface 1112 of the sewage tank 111 to tilt. On the one hand, the speed at which the sewage in the sewage tank 111 flows out of the sewage tank 111 is increased, thereby increasing the possibility of the garbage being carried out of the sewage tank 111. On the other hand, the heavier garbage originally gathered on the bottom surface 1112 of the sewage tank 111 will automatically flow to the sewage outlet of the sewage tank 111 under the influence of its own gravity, thereby facilitating the garbage collection by the base station.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
