[0062] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0063] The present invention relates to a cleaning tool, which can be used for cleaning the floor, in particular a small smooth and flat floor, such as a home and kitchen floor. The cleaning tool of the present invention is particularly suitable for cleaning mixed garbage containing dry garbage, wet garbage and viscous materials such as noodles, porridge, ketchup and the like.

[0064] The dry garbage mentioned in the present invention specifically refers to granular garbage, such as fruit peels, melon seed shells, rice grains, paper scraps, etc.

[0065] Wet garbage refers to liquid garbage, such as water, beverages, etc.

[0066] Sticky garbage (or sticky garbage) includes soup, stew, porridge, ketchup, chocolate sauce and other garbage with a certain viscosity.

[0067] Other garbage also includes dust, ground marks, etc., which are also cleaning objects of the present invention.

[0068] Figure 1 to Figure 4 The double-drum sweeping robot 100 of the present invention is shown, which comprises a housing 110, a first drum 120, and a second drum 130. The first drum 120 and the second drum 130 are mounted on the housing 110. The housing 110 is provided with a clean water tank 111 and a dirty water tank 112. Figure 1 In the illustrated embodiment, the clean water tank 111 is disposed above the first drum 120 and the second drum 130 , and the dirty water tank 112 is disposed between the first drum 120 and the second drum 130 .

[0069] The first roller 120 and the second roller 130 are connected to the sewage tank 112 respectively. Figure 1In the embodiment shown, the walls of the sewage tank 112 close to the first roller 120 and the second roller 130 extend outward to form a first squeezing strip 112a and a second squeezing strip 112b. The ends of the first squeezing strip 112a and the second squeezing strip 112b interfere with the first roller 120 and the second roller 130 (i.e., squeeze the rollers).

[0070] The first water squeezing bar 112a and the second water squeezing bar 112b have an inclined surface which has a drainage function. The sewage squeezed out from the first roller 120 and the second roller 130 at the ends of the first water squeezing bar 112a and the second water squeezing bar 112b flows into the sewage tank 112 along the surface.

[0071] The first roller 120 and the second roller 130 include an inner layer of hard rubber and a sponge layer wrapped outside the hard rubber. The end of the hard rubber can be fixed to the housing 110 through a connecting piece such as a bearing. The roller driving mechanism drives the hard rubber to rotate around its axis through the roller transmission mechanism, driving the roller to rotate, so that the surface of the roller moves in a circular motion. During operation, the first roller 120 and the second roller 130 rotate in opposite directions (as shown by the arrow direction in the figure, one rotates clockwise and the other rotates counterclockwise), and the first squeezing strip 112a and the second squeezing strip 112b interfere with the first roller 120 and the second roller 130 at point A and point B respectively, thereby squeezing out the sewage in the first roller 120 and the second roller 130. Optionally, the interference amount between the ends of the first squeezing strip 112a and the second squeezing strip 112b and the first roller 120 and the second roller 130 is 0.5 to 7 mm. Under this interference amount, it can be ensured that the sewage is squeezed out from the roller without damaging the surface of the roller. The speeds of the first roller 120 and the second roller 130 are preferably set to be the same.

[0072] In this embodiment, a dual-drum sweeping robot 100 is provided with a universal wheel 140 at one end, a driving wheel 150 in the middle, and an auxiliary wheel 160 at the other end. The driving wheel 150 is driven by a driving motor (independent of the driving motor of the drum) and is connected to the driving motor through a driving gear 151. In this embodiment, there are two left and right driving wheels 150 (such as Figure 2 , Figure 3 shown).

[0073] A clean water tank button 113 and a dirty water tank button 114 are provided on the top of the housing 110. Pressing the clean water tank button 113 can open the clean water inlet of the clean water tank 111. Pressing the dirty water tank button 114 can open the dirty water outlet 112a of the dirty water tank 112.

[0074] Optionally, the sewage outlet 112a is disposed at the bottom of the housing 110 (eg Figure 2 shown).

[0075] Figure 3The process of the sewage tank button 114 opening the sewage outlet of the sewage tank 112 is shown. The sewage tank button 114 is pressed, and it moves downward, pressing down one end of the connecting rod 115, and the other end of the connecting rod 115 is lifted up, which is connected with the plug 116 of the sewage outlet, driving the plug 116 to move upward, thereby opening the sewage outlet.

[0076] Optionally, a first clean water pump 170 and a clean water pipe 180 are provided inside the cleaning robot 100. Figure 4 As shown, the clean water pipe 180 is respectively connected to the first clean water pump 170, the clean water inlet 117, and the clean water outlet 118. Optionally, there are two clean water outlets 118, which are respectively located above the first drum 120 and the second drum 130 (not shown in the figure).

[0077] The sweeping robot of the present invention can be used for mopping the floor and cleaning wet garbage and sticky garbage on the floor.

[0078] When mopping the floor (only the floor needs to be moistened), clean water is sprayed from the clean water tank to the sponge layers on the surfaces of the first roller and the second roller, so that the rollers saturated with water moisten the floor.

[0079] When there is dust or marks on the ground, clean water is sprayed from the clean water tank to the surface of the first roller and the second roller, so that the sponge layers of the first roller and the second roller saturated with water remove the dust and marks from the ground, and the first extrusion bar and the second extrusion bar interfere with the first roller and the second roller respectively, thereby squeezing out the sewage in the first roller and the second roller. The sewage flows into the sewage tank along the inclined surfaces of the first extrusion bar and the second extrusion bar.

[0080] When there is wet garbage on the ground, the sponge layers of the first and second rollers absorb the wet garbage. The wet garbage moves along with the first and second rollers, and when it reaches the first and second squeezing bars, the first and second squeezing bars squeeze the sponge layers of the first and second rollers, and the wet garbage is released from the sponge layers and flows into the sewage tank along the inclined surfaces of the first and second squeezing bars with the water flow.

[0081] When there is sticky garbage on the ground, the sticky garbage adheres to the sponge layer of the first roller and the second roller, and partially penetrates into the sponge layer. The first roller and the second roller rotate and reach below the clean water outlet, and the clean water is sprayed onto the surface of the sponge layer, flushing the sticky garbage adhered to the surface of the sponge layer into the sewage tank. When it runs to the first extrusion bar and the second extrusion bar, the first extrusion bar and the second extrusion bar can also play a scraping role, and under the joint action of the first extrusion bar, the second extrusion bar and the water flow, the sticky garbage that penetrates into the sponge layer will be released, and the sticky garbage adhered to the sponge layer will also be removed and enter the sewage tank with the water flow.

[0082] Figures 5 to 8A cleaning pile 200 of the present invention is shown. Figure 5 , Figure 6 As shown, the main body 210 of the cleaning pile 200 is provided with a clean water box 211, a first dirty water box 212, and a second dirty water box 213. The clean water box 211 is used to supply water to the clean water tank 111 of the sweeping robot 100, and the first dirty water box 212 and the second dirty water box 213 are used to hold the dirty water in the dirty water tank 112. Figure 6 As shown, the cleaning pile 200 is also provided with a second clean water pump 220 and a sewage pump 230 installed in the body 210. When the cleaning robot 100 enters the cleaning pile 200, the sewage in the sewage tank 112 of the cleaning robot 100 can flow into the first sewage box 212 by its own weight. The cleaning pile 200 is provided with a sewage inlet 216, and when the cleaning robot 100 enters the cleaning pile 200, its position corresponds to the sewage outlet 112a of the sewage tank 112 of the cleaning robot 100. The clean water pump 220 is used to pump the clean water in the clean water box 211 into the clean water tank 111, and the sewage pump 230 is used to pump the sewage in the first sewage box 212 into the second sewage box 213.

[0083] Alternatively, if Figure 5 and Figure 7 As shown, the cleaning pile 200 may be provided with a clean water ejector pin 214 and a sewage ejector pin 215. The clean water ejector pin 214 is used to press the clean water tank button 113, thereby injecting clean water in the clean water box 211 into the clean water tank 111. The sewage ejector pin 215 is used to press the sewage tank button 114, thereby discharging sewage in the sewage tank 112 into the first sewage box 212. When the clean water ejector pin 214 and the sewage ejector pin 215 move downward, the clean water tank 111 and the sewage tank 112 (such as the first sewage box 212) of the sweeping robot are opened respectively. Figure 8 shown).

[0084] In other embodiments of the present invention, the cleaning robot may include a first control module and a first detection module installed in the housing. Optionally, the first control module may be used to perform the following operations:

[0085] Determine the position and cleaning environment of the sweeping robot through the first detection module; and

[0086] Control the sweeping robot to clean up the garbage on the ground.

[0087] At this time, the first detection module is used to detect the position and cleaning environment of the sweeping robot. Then the first control module determines the position and cleaning environment of the sweeping robot according to the information fed back by the first detection module. Then the first control module controls the sweeping robot to clean up the garbage on the ground (mainly wet garbage and sticky garbage).

[0088] Alternatively, if Fig. 9 As shown, the first control module can be used to perform the following operations:

[0089] S91: Determine the position and cleaning environment of the sweeping robot through the first detection module.

[0090] For example, when a sweeping robot is placed in a room, it will first determine its position in the room and the specific conditions of the room through the first detection module. The specific conditions of the room include but are not limited to obstacles in the room (such as sofas, coffee tables, beds, etc.) and the cleanliness of the floor (the amount of garbage, the distribution of garbage, etc.).

[0091] In order to make the detection more accurate, optionally, multiple first detection modules can be provided. The functions of the multiple detection modules can also be set to be different, for example, some are used to specifically detect obstacles in the room, and another is used to specifically detect the cleanliness of the floor.

[0092] S92: Plan cleaning routes.

[0093] According to its location and the cleaning environment of the room, it plans its cleaning route in the room, such as avoiding obstacles, cleaning multiple times in places with more garbage, cleaning the entire room multiple times, etc.

[0094] S93: Control the sweeping robot to clean up the garbage on the ground according to the cleaning route.

[0095] After the cleaning route is planned, control the sweeping robot to clean up the garbage on the ground according to the cleaning route.

[0096] Optionally, after cleaning, the cleaning environment can be checked again. If the ideal cleaning level is not achieved, the cleaning route can be planned again for cleaning.

[0097] Optionally, the first detection module can also be used to detect the amount of water in the clean water tank and / or the sewage tank. For example, when the amount of clean water in the clean water tank is lower than a set amount (such as no water), the first control module stops the sweeping robot from cleaning, or an audio module can be set in the sweeping robot for sound prompts (such as dripping sounds or voice broadcasts). When the amount of sewage in the sewage tank is higher than a set amount (such as full), the first control module stops the sweeping robot from cleaning, or an audio module can be set in the sweeping robot for sound prompts (such as dripping sounds or voice broadcasts).

[0098] Alternatively, if Fig.10 As shown, the first check control block can also be used to perform the following operations:

[0099] S101: Determine the positional relationship between the sweeping robot and the cleaning pile through a first detection module.

[0100] In order to determine the positional relationship more accurately, a positioning module may be additionally provided on the cleaning pile. Of course, the external environment may also be scanned by only the first detection module to determine the positional relationship between the external environment and the cleaning pile.

[0101] S102: Planning a travel route according to the position relationship.

[0102] S103: Control the sweeping robot to move to the cleaning pile according to the travel route.

[0103] After entering the cleaning pile, you can only use the clean water pump to replenish the clean water tank of the sweeping robot. Of course, you can also only drain the sewage in the sewage tank of the sweeping robot, and of course both can be done at the same time. When they are done at the same time, clean water keeps entering and sewage keeps flowing out, which is equivalent to cleaning the drum.

[0104] A second detection module, a second control module, a clean water pump, and a sewage pump can be arranged in the cleaning pile.

[0105] Alternatively, if Fig.11 As shown, the second control module is used to perform the following operations:

[0106] S111: Determine whether the sweeping robot enters the cleaning pile through the second detection module.

[0107] Here, whether to enter the cleaning pile may include states such as not entering, entering but not in place, in place, etc. Optionally, in these states, an audio module may be provided in the cleaning pile for sound prompts (such as beeping or voice broadcast).

[0108] S112: When the sweeping robot enters the cleaning pile, the clean water ejector pin is controlled to move downward and the clean water tank button is pressed.

[0109] The sweeping robot described here entering the cleaning pile refers to the "in place" state described above.

[0110] S113: Start the clean water pump to pump the clean water in the clean water box into the clean water tank.

[0111] In this case, the cleaning pile only replenishes clean water to the sweeping robot.

[0112] Alternatively, if Fig.12 As shown, the second control module is used to perform the following operations:

[0113] S121: Determine whether the sweeping robot enters the cleaning pile through the second detection module.

[0114] As before, whether to enter the cleaning pile may include the states of not entering, entering but not in place, in place, etc. Optionally, in these states, an audio module may be provided in the cleaning pile for sound prompts (such as beeping or voice broadcast).

[0115] S122: When the sweeping robot enters the cleaning pile, the sewage ejector pin is controlled to move downward and the sewage tank button is pressed.

[0116] The sweeping robot described here entering the cleaning pile refers to the "in place" state described above.

[0117] S123: Open the sewage inlet of the first sewage box, and the sewage in the sewage tank enters the first sewage box.

[0118] S124: Start the sewage pump to pump the sewage in the first sewage box to the second sewage box.

[0119] At this point, all the sewage in the sewage tank of the sweeping robot is discharged to the cleaning pile. The second sewage box can be set to be detachable, so as to facilitate cleaning and pouring out the sewage.

[0120] Of course, the second control device can simultaneously control the cleaning pile to replenish clean water and drain sewage to the sweeping robot, that is:

[0121] Determine whether the sweeping robot has entered the cleaning pile by the second detection module;

[0122] When the sweeping robot enters the cleaning pile, control the water ejector pin to move downward and press the water tank button;

[0123] Start the clean water pump to pump the clean water in the clean water box into the clean water tank;

[0124] Control the sewage ejector pin to move downward and press the sewage tank button;

[0125] Open the sewage inlet of the first sewage box, and the sewage in the sewage tank enters the first sewage box;
