[0039] An embodiment of the cleaning module provided by the present invention is described as follows. Please refer to Figures 1 to 4 , the cleaning module 1 includes a box body 2, at least one turntable assembly 3 and at least one driving mechanism 4. Among them, the driving mechanism 4 is disposed on the bottom surface of the box body 2 and has at least one driving shaft 40. Each turntable assembly 3 is connected to a driving shaft 40 and has a cleaning surface, and the cleaning surface rotates under the drive of the driving shaft 40 for cleaning the surface to be cleaned.

[0040] In this embodiment, by disposing the driving mechanism 4 on the bottom surface of the box body 2, and the driving mechanism 4 is connected to the turntable assembly 3, the driving mechanism 4 and the turntable assembly 3 are integrated on the box body 2 to form the cleaning module 1. The driving mechanism 4 drives the turntable assembly 3 to rotate, and the cleaning surface of the turntable assembly 3 rotates to clean the ground. Since the box body 2 is detachably installed on the body of the cleaning robot, compared with the driving mechanism built in the body, when the driving mechanism 4 fails, the cleaning module 1 is easy to replace and repair.

[0041] In the present invention, it can be understood that the number of the turntable assembly 3 and the driving mechanism 4 can be set according to actual needs. For example, when the cleaning module 1 has only one turntable assembly 3, the number of the driving mechanisms 4 is also 1, and there is only one driving shaft 40, and the driving shaft 40 is connected to the turntable assembly 3. When the cleaning module 1 has two turntable assemblies 3, the number of the driving mechanisms 4 can be 1, and there are two driving shafts 40. One driving shaft 40 is connected to one turntable assembly 3, and then the driving mechanism 4 drives the two turntable assemblies 3 to rotate in opposite directions. When the cleaning module 1 has two turntable assemblies 3, the number of the driving mechanisms 4 is also 2. One driving mechanism 4 has one driving shaft 40, and one driving shaft 40 is connected to one turntable assembly 3. When the cleaning module 1 has three turntable assemblies 3, the number of the driving mechanisms 4 can be 1, 2 or 3, and three driving shafts 40 of one driving mechanism 4 can respectively drive the three turntable assemblies 3 to rotate. When the cleaning module 1 has four turntable assemblies 3, the number of the driving mechanisms 4 can be 1, 2 or 4, and four driving shafts 40 of one driving mechanism 4 can respectively drive the four turntable assemblies 3 to rotate.

[0042] In this embodiment, at least one groove 20 is provided on the bottom surface of the box body 2, and each groove 20 houses at least one driving mechanism 4. Since the driving mechanism 4 is housed in the groove 20, the main body part of the driving mechanism 4 will not protrude from the bottom surface of the box body 2, thereby reducing the height of the entire cleaning module 1 and avoiding too large a distance between the turntable assembly 3 and the bottom surface of the box body 2.

[0043] In the present invention, it can be understood that the number of grooves 20 can be set according to actual needs, and the number of driving mechanisms 4 housed in a single groove 20 can also be adjusted according to actual needs. For example, one groove 20 can house one driving mechanism 4, or two driving mechanisms 4, or even all driving mechanisms 4. In addition, in other embodiments of the present invention, the driving mechanism 4 can be directly installed on the bottom surface of the box body 2, that is, the driving mechanism 4 protrudes as a whole relative to the bottom surface of the box body 2, which also solves the technical problem of the present invention.

[0044] In this embodiment, the box body 2 includes at least one bottom cover 200 and at least one first sealing ring 202, and the bottom cover 200 and the first sealing ring 202 are arranged corresponding to the groove 20. The bottom cover 200 covers the periphery of the groove 20, and the first sealing ring 202 is located between the bottom cover 200 and the periphery of the groove 20. The driving shaft 40 penetrates the opening of the bottom cover 200. The first sealing ring 202 serves to seal the driving mechanism 4. At the same time, in order to ensure the sealing between the opening and the driving mechanism 4, a second sealing ring is provided between the periphery of the opening of the bottom cover 200 and the surface of the driving mechanism 4.

[0045] In this embodiment, each turntable assembly 3 includes a turntable 30 and a cleaning member 32. The turntable 30 is connected to the driving shaft 40. The cleaning member 32 is installed on the surface of the turntable 30 facing away from the driving mechanism 4, and the cleaning surface is provided on the surface of the cleaning member 32 facing away from the turntable 30. The turntable 30 can install and support the cleaning member 32, and when the cleaning member 32 cleans the ground, the turntable 30 presses the cleaning member 32 to improve the cleaning effect.

[0046] In the present invention, it can be understood that the cleaning liquid can be output from the box body 2 to the cleaning member 32 to wet the cleaning member 32, thereby realizing the scrubbing of the ground. The cleaning liquid can also be transmitted from other containers of the cleaning robot to the cleaning member 32 through the liquid delivery mechanism to wet the cleaning member 32, thereby realizing the scrubbing of the ground. The cleaning liquid can also be directly sprayed from the body of the cleaning robot or the box body 2 onto the ground to wet the ground, and the cleaning member 32 rotates to scrub the ground.

[0047] In this embodiment, the turntable 30 has a bushing 300, and the bushing 300 is sleeved on a drive shaft 40. Specifically, the drive shaft 40 is polygonally arranged, the bushing 300 is provided with a polygonal shaft hole, and the drive shaft 40 is adapted to the shaft hole of the bushing 300. Preferably, the drive shaft 40 is a pentagonal shaft, and the shaft hole correspondingly is a pentagonal shaft hole. Moreover, the turntable assembly 3 further includes a screw. A screw hole is formed in the end face of the drive shaft 40, a connection hole is formed in the bushing 300, and the screw is inserted into the screw hole from the connection hole to lock the turntable 30 and the drive shaft 40. Of course, in other embodiments of the present invention, the drive shaft 40 can be fixedly connected with the bushing 300 by a tight fit or the drive shaft 40 and the bushing 300 can be snap-connected.

[0048] In this embodiment, the box body 2 further includes a liquid cavity 220 for storing a cleaning liquid. At least one liquid outlet 221 spaced from the groove 20 is provided on the bottom surface of the box body 2, and each liquid outlet 221 is used to communicate with the liquid cavity 220 to output the cleaning liquid. An annular liquid groove 302 is provided on the surface of each turntable 30 facing the driving mechanism 4. The annular liquid groove 302 corresponds to at least one liquid outlet 221, and a plurality of through holes 304 are provided at the bottom of the annular liquid groove 302. The annular liquid groove 302 can always receive the liquid flowing out from the liquid outlet 221 when the turntable 30 rotates, and flow to the cleaning member 32 through the through holes 304. Further, the plurality of through holes 304 being uniformly distributed in the radial direction can ensure that the cleaning member 32 is uniformly wetted. It should be noted that in other embodiments of the present invention, a liquid guiding pipeline can be provided between the liquid outlet 221 and the annular liquid groove 302, and the liquid guiding pipeline does not affect the rotation of the turntable 30.

[0049] In the present invention, it can be understood that the liquid outlet 221 can be communicated with a flow channel provided at the bottom of the liquid cavity 220 to output the liquid under the action of gravity. The liquid outlet 221 can also be communicated with a pipeline structure provided in the liquid cavity 220, and the liquid flows to the liquid outlet 221 through the pipeline structure by using gravity or air pressure.

[0050] Please refer to Figure 5 and Figure 6 , in this embodiment, the box body 2 further includes at least one liquid outlet column 226 and a communication component. At least one liquid outlet column 226 is provided at the bottom of the liquid cavity 220. An inlet is provided at one end of each liquid outlet column 226, and a liquid outlet 221 is provided at the other end of each liquid outlet column 226. The inlet is higher than the highest liquid level of the liquid cavity 220. The communication component is provided in the liquid cavity 220 and respectively communicates with the inlets of each liquid outlet column 226. The communication component has an input end, and the input end is arranged below the highest liquid level for inputting the cleaning liquid and transmitting it to each inlet.

[0051] Since the liquid inlet of the liquid outlet column 226 is higher than the highest liquid level of the liquid cavity 220, when it is installed on the robot main body, when the air pressure in the liquid cavity 220 does not reach the preset condition, the liquid cannot enter the liquid inlet, thereby avoiding the liquid leakage when the cleaning robot is not working. It can be understood that gas can be input into the liquid cavity 220 through a built-in or external air pump mechanism to increase the air pressure inside the liquid cavity 220 to meet the liquid supply requirement, and at the same time, the liquid supply amount can be accurately controlled.

[0052] Please refer to Figures 3 to 6 , in this embodiment, at least one turntable assembly 3 is specifically two turntable assemblies 3, the two turntable assemblies 3 are arranged side by side, and each turntable assembly 3 is connected to a drive shaft 40. At least one drive mechanism 4 is specifically two drive mechanisms 4, each drive mechanism 4 is arranged corresponding to one turntable assembly 3, and there is only one drive shaft 40. Driving one turntable assembly 3 to work through one drive mechanism 4 can simplify the drive mechanism 4 and facilitate controlling the rotation directions of the two turntable assemblies 3. It should be noted that the side-by-side arrangement means arranging side by side in the cleaning direction of the cleaning robot, that is, the arrangement direction of the two turntable assemblies 3 is basically perpendicular to the cleaning direction, so that the maximum cleaning width of the cleaning robot can be guaranteed.

[0053] In this embodiment, at least two liquid outlets 221 are provided, and correspondingly, two liquid outlet columns 226 are provided in the liquid cavity 220. Among them, one liquid outlet 221 is arranged corresponding to the annular liquid groove 302 of one turntable 30.

[0054] In this embodiment, two grooves 20 are provided at intervals on the bottom surface of the box body 2, and each groove 20 houses a drive mechanism 4.

[0055] In this embodiment, the peripheries of the cleaning members 32 of the two turntable assemblies 3 arranged side by side extend beyond the periphery of the turntable 30, so that the two cleaning members 32 are in contact. Since the two cleaning members 32 are in contact, it is avoided that an uncleaned blank area is formed at the adjacent position of the two cleaning members 32, and the overall cleaning effect is improved. It should be noted that in other embodiments, a turntable assembly 3 can also be added in front of or behind the two turntable assemblies 3 to clean the uncleaned blank area through the newly added turntable assembly 3.

[0056] In this embodiment, the cleaning member 32 is attached to the surface of the turntable 30, and the cleaning members 32 of the two turntable assemblies 3 arranged side by side are pressed against each other. Since the cleaning members 32 are attached and arranged, the two cleaning members 32 pressed against each other will not be deformed or bent, which can further improve the cleaning effect at the adjacent position of the two cleaning members 32. Moreover, when cleaning the ground, the cleaning surface of the cleaning member 32 can be guaranteed to be flat under the extrusion of the turntable 30.

[0057] In this embodiment, each cleaning member 32 includes a cleaning body and a plurality of cleaning villi, and the plurality of cleaning villi are arranged on the circumferential side surface of the cleaning body. The cleaning villi of two adjacent cleaning members 32 extend alternately with each other, which is beneficial to further improve the cleaning effect at the adjacent position of the two cleaning members 32.

[0058] In this embodiment, a plurality of cleaning villi are also arranged on the surface of the cleaning body facing away from the turntable 30. The cleaning villi can increase the friction coefficient and improve the floor mopping effect, especially the dirt adhering to the ground.

[0059] In this embodiment, the cleaning member 32 is detachably mounted on the turntable 30, which is convenient for replacement and installation and can improve the user experience.

[0060] In this embodiment, each turntable assembly 3 further includes a plurality of magic tapes, and the plurality of magic tapes are arranged between the turntable 30 and the cleaning member 32. In other embodiments of the present invention, the cleaning member 32 can be detachably mounted through a clamping structure.

[0061] Please refer to FIGS. 3 to Figure 7 , in this embodiment, the box body 2 further includes a receiving cavity 222, the receiving cavity 222 is isolated from the liquid cavity 220, and communicates with the two grooves 20 to receive parts of the two driving mechanisms 4. Since parts of the two driving mechanisms 4 are received in the receiving cavity 222, it is convenient to electrically connect the driving mechanisms 4.

[0062] In this embodiment, the cleaning module 1 further includes an air pump mechanism 5, and at least part of the air pump mechanism 5 is received in the receiving cavity 222. The air pump mechanism 5 includes an air pump 50 and an air delivery channel. The air pump 50 is received in the receiving cavity 222, the air delivery channel communicates with the air pump 50, penetrates through the isolation between the receiving cavity 222 and the liquid cavity 220, and communicates with the liquid cavity 220.

[0063] Since the air pump mechanism 5 is built in the receiving cavity 222 and the air delivery channel of the air pump mechanism 5 communicates with the liquid cavity 220, the problem of poor airtightness at the connection between the external air pump mechanism and the water tank is overcome, and the stability of the air supply of the air pump mechanism is improved. At the same time, when the air pump 50 works, it generates gas, and the gas is input into the liquid cavity 220 through the air delivery channel. The air pressure in the liquid cavity 220 increases, and the cleaning liquid in the liquid cavity 220 is output from the liquid outlet 221 under the action of the air pressure and drips into the annular liquid groove 302 of the turntable 30, and then flows to the cleaning member 32 through the through hole 304 of the annular liquid groove 302. Therefore, the output of the liquid can be accurately controlled by the air pump 50, avoiding excessive liquid output resulting in a wet floor, and at the same time avoiding too little liquid output affecting the scrubbing effect.

[0064] In this embodiment, the box body 2 includes a bottom shell 22 and a top cover 24 covering the bottom shell 22. The bottom shell 22 and the top cover 24 are closed to form a liquid cavity 220 and a receiving cavity 222. The air pump mechanism 5 is arranged on the top cover 24, that is, the air pump mechanism 5 is located at a relatively high position, which can prevent water from entering the air outlet of the air delivery channel during air delivery.

[0065] In this embodiment, the box body 2 further includes a mounting bracket 56. Both ends of the mounting bracket 56 are fixed on the top cover 24; a card slot 242 is provided on the inner surface of the top cover 24; the air pump 50 is installed in the card slot 242 and is located between the mounting bracket 56 and the top cover 24. The card slot 242 houses the air pump 50, and the mounting bracket 56 and the top cover 24 clamp the air pump 50, thereby positioning the air pump 50 with good fixing effect. It can be understood that in other embodiments of the present invention, the air pump 50 can be fixed on the top cover 24 by other means, such as bonding or snap connection.

[0066] In this embodiment, the card slot 242 has two opposite side walls, and one of the side walls is formed at the isolation location between the receiving cavity 222 and the liquid cavity 220, making full use of the internal structure of the receiving cavity 222 and simplifying the setting of the card slot 242.

[0067] In this embodiment, at least one rib 243, 244 is provided on each side wall; the air pump 50 has two opposite side surfaces, and the two side surfaces are clamped between the ribs 243, 244 on the two side walls.

[0068] In this embodiment, the mounting bracket 56 is provided with a mounting groove 560. The mounting groove 560 houses a part of the air pump 50, and the mounting groove 560 cooperates with the card slot 242 to house and position the entire air pump 50, and its mounting and fixing effect is good.

[0069] In this embodiment, the air delivery channel includes a first pipe and a second pipe 52. Among them, one end of the first pipe is connected to the air pump 50, and the other end is connected to one end of the second pipe 52; the second pipe 52 is arranged on the top cover 24, and the other end of the second pipe 52 penetrates through the isolation location between the receiving cavity 222 and the liquid cavity 220 and extends into the liquid cavity 220. Since the second pipe 52 is arranged on the top cover 24 and is higher than the liquid level in the cavity, it can prevent the other end of the second pipe 52 from entering the liquid.

[0070] In this embodiment, the first pipe is a soft rubber pipe, which is bent. When liquid enters it, under the action of gravity, it deforms to prevent the liquid from directly entering the air pump 50.

[0071] In this embodiment, the air delivery channel further includes a third pipe 54. One end of the third pipe 54 is connected to the other end of the second pipe 52, and the other end is arranged close to the bottom of the liquid cavity 220. Since the other end of the third pipe 54 is arranged close to the bottom of the liquid cavity 220, when the box body 2 is inverted, the liquid level in the liquid cavity 220 is usually lower than the other end of the third pipe 54, thus preventing liquid from flowing in.

[0072] In this embodiment, the liquid outlets 221 of the two liquid outlet columns 226 arranged side by side correspond to the two turntable assemblies 3. The connecting component includes a tee and an input pipe. One outlet of the tee is connected to the liquid inlet of one liquid outlet column 226 through a pipeline, and the other outlet is connected to the liquid inlet of the other liquid outlet column 226 through a pipeline. One end of the input pipe is connected to the inlet of the tee, and the other end forms an input end.

[0073] When the air pump 50 works, the air pressure in the liquid chamber 220 increases. The liquid is pressed into through the input end of the input pipe, flows into through the inlet of the tee, flows out from the two outlets of the tee, and then enters the liquid inlets of the two liquid outlet columns 226, and finally flows through the liquid outlet columns 226 and flows out from the liquid outlets 221. When the air pump 50 does not work, the liquid inlet of the liquid outlet column 226 is higher than the highest liquid level of the liquid chamber 220, and the liquid cannot enter the liquid inlet.

[0074] In this embodiment, the input end is arranged close to the bottom of the liquid chamber 220. When the liquid level in the liquid chamber 220 drops to the lowest, the liquid can also be output to the turntable assembly 3 through the input end under the action of air pressure.

[0075] In this embodiment, the box body 2 further includes a support column 227. The support column 227 is arranged at the bottom of the liquid chamber 220, and the tee is installed on the support column 227. The support column 227 plays a role in supporting the tee. In order to better avoid the problem of liquid leakage, the top end of the support column 227 can be higher than or flush with the liquid inlet of the liquid outlet column 226.

[0076] In this embodiment, the support column 227 is provided with a guide groove, and the input pipe is installed in the guide groove and led to the bottom of the liquid chamber 220. The input pipe and the pipeline connected to the tee are both soft rubber hoses. A protrusion is provided at the top end of the liquid outlet column 226, and the liquid inlet is formed on the protrusion, which is convenient for inserting the nozzle of the soft rubber hose into the protrusion to connect the liquid inlet.
