[0033] Please refer to Figures 1 to 13 , this embodiment provides a cleaning module, which includes a housing 1, a roller brush unit, a side brush assembly 3, a spraying assembly, a garbage collection box 5, and a water scraping assembly 6. This cleaning module has the functions of dry mopping, wet mopping, sweeping, garbage collection, water scraping, and cleaning the corners. It is a multi-functional cleaning module, which is quite different from the cleaning device with only a single mopping function in the prior art. The cleaning module of this embodiment can be applied to a variety of cleaning robots, generally installed at the bottom of the cleaning robot. The robot applying this cleaning module can perform various cleaning operations such as dry mopping, mopping with water, collecting garbage, cleaning the corners, and scraping water on the ground.

[0034] As Figure 1 shown, an opening is provided at the bottom of the housing 1 of this embodiment. The housing 1 has a cuboid-shaped structure and is used to connect the other components of the cleaning module.

[0035] As Figures 1 - 2As shown in the figure, the brush roller unit in this embodiment includes a brush roller 21, a first connection component 22, a second connection component 23, a locking component 24, and a brush roller drive component 25. The brush roller 21 is disposed within the housing 1, and its two ends are respectively inserted and mated with the first connection component 22 and the second connection component 23; the first connection component 22 and the second connection component 23 are respectively disposed on opposite sides of the housing 1, and the first connection component 22 is fixedly connected to the housing 1, the second connection component 23 is slidably mated with the housing 1, and is mutually fixed to the housing 1 through the locking component 24; the brush roller drive component 25 is disposed on the housing 1 and is connected to the first connection component 22 to drive the brush roller 21 to rotate.

[0036] Due to the above-mentioned brush roller unit, the two ends of the brush roller 21 are respectively connected to the first connection component 22 and the second connection component 23 through an inserted mating method, and the second connection component 23 is connected to the housing 1 through a sliding mating method and is fixed to the housing 1 through a locking component 24, making the disassembly of the brush roller 21 very convenient. During disassembly, only the locking component 24 needs to be removed first, and then the second connection component 23 is slid out of the housing 1, and the two ends of the brush roller 21 can be separated from the first connection component 22 and the second connection component 23. During installation, one end of the brush roller 21 is first inserted into the first connection component 22, then the second connection component 23 is inserted into the other end of the brush roller 21, and finally the second connection component 23 is slid into the housing 1 and the locking component 24 is fastened. The brush roller 21 of the cleaning module in this embodiment is very convenient to disassemble and install, which can greatly improve work efficiency and is convenient for maintenance.

[0037] In this embodiment, the inside of the brush roller 21 is a roller shaft, and brushes are provided on the roller shaft. Driven by the brush roller drive component 25, the roller shaft rotates and drives the brushes to clean, so that the ground at the bottom of the housing 1 is cleaned.

[0038] As Figure 3 shown, specifically, in this embodiment, the first connection component 22 includes a first connection seat 221 and a first connection shaft 222. The first connection seat 221 is fixedly connected to the side surface of the housing 1. One end of the first connection shaft 222 is rotatably connected to the first connection seat 221, and the other end is inserted into the end of the brush roller 21. The brush roller drive component 25 drives the first connection shaft 222 to rotate, thereby driving the brush roller 21 to rotate. Specifically, a bearing is provided in the first connection seat 221, and the first connection shaft 222 is rotatably connected to the first connection seat 221 through the bearing.

[0039] As Figure 4 shown, the second connection component 23 includes a second connection seat 231 and a second connection shaft 232. As Figure 5As shown, on one side of the housing 1 close to the second connection assembly 23, two oppositely arranged limit blocks 11 and a positioning block 12 are fixedly connected. On the opposite sides of the two limit blocks 11, a limit chute 111 is provided. The limit chute 111 extends in the vertical direction, and the positioning block 12 is located at the top of the limit chute 111. In this embodiment, the second connection seat 231 of the second connection assembly 23 is slidably engaged with the housing 1 through the limit blocks 11. Specifically, both ends of the second connection seat 231 are inserted into the limit chutes 111 and slide along the limit chutes 111 until they abut against the positioning block 12. The final position of the second connection seat 231 is as Figure 6 shown. The locking part 24 fixes the second connection seat 231 and the housing 1 to each other. At this time, the second connection seat 231 is installed in place, and accurate positioning is achieved under the cooperation of the limit blocks 11 and the positioning block 12. Under the connection of the locking part 24, it is firmly fixed. One end of the second connection shaft 232 is rotatably connected to the second connection seat 231, and the other end is inserted into the end of the roller brush 21. Specifically, a bearing is provided in the second connection seat 231, and the second connection shaft 232 is rotatably connected to the second connection seat 231 through the bearing.

[0040] It can be seen that the first connection assembly 22 and the second connection assembly 23 in this embodiment respectively insert the two ends of the roller brush 21 through the first connection shaft 222 and the second connection shaft 232, which can make the disassembly and assembly operations more convenient. When the roller brush 21 rotates, the first connection shaft 222 and the second connection shaft 232 rotate in the first connection seat 221 and the second connection seat 231 respectively. To facilitate insertion and drive the roller brush 21, as Figures 3 - 4 shown in and 7, preferably, the first connection shaft 222 and the second connection shaft 232 in this embodiment are both convexly provided with insertion parts 201, and both ends of the roller brush 21 are concavely provided with insertion slots 202 adapted to the insertion parts 201. The insertion parts 201 extend radially, and the number of insertion parts 201 on each connection shaft can be designed according to actual needs. In this embodiment, it is set to two.

[0041] As Figure 8 shown, specifically, the locking part 24 in this embodiment is a tower buckle lock, which is simple to operate and firmly connected. The tower buckle lock is a common locking part in the prior art. It generally includes a lock base 241, a lock body 242, a lock tongue 243 and a lock tongue seat 244. The bottom end of the lock body 242 is hinged to the lock base 241, and the top end is hinged to the lock tongue 243. The lock body 242 locks the lock tongue seat 244 by pulling the lock tongue 243. As Figure 9As shown, in this embodiment, the lock base 241 of the tower buckle lock is fixedly arranged on the positioning block 12, and the lock tongue base 244 of the tower buckle lock is fixedly arranged on the second connecting seat 231. By operating the lock body 242, the lock tongue 243 is engaged with the lock tongue base 244, so that the second connecting seat 231 is fixed to the positioning block 12 on the housing 1.

[0042] As Figure 10 shown, specifically, the roller brush driving assembly 25 in this embodiment includes a roller brush driving motor 251, a driving wheel 252, a driven wheel 253 and a transmission belt 254. The roller brush driving motor 251 is arranged on the top of the housing 1. The driving wheel 252 is connected to the output shaft of the roller brush driving motor 251. The driven wheel 253 is connected to one end of the first connecting shaft 222. The transmission belt 254 is sleeved outside the driving wheel 252 and the driven wheel 253. With such an arrangement, the roller brush driving assembly 25 can stably drive the first connecting shaft 222 to rotate, and then drive the roller brush 21 to rotate. Moreover, the driving wheel 252 and the driven wheel 253 are connected by the transmission belt 254, and the structure is simple and easy to assemble.

[0043] The roller brush unit in this embodiment is arranged along the left - right direction of the housing 1, that is, the center line of the roller brush 21 is parallel to the left - right direction of the housing 1. The number of the roller brush units can be set to multiple to achieve a better floor - brushing effect. Specifically, in this embodiment, the roller brush units are set to two. The roller brushes 21 in the two roller brush units are arranged in parallel, and the two roller brushes 21 rotate in opposite directions, which can achieve a better floor - brushing effect.

[0044] The garbage collection box 5 in this embodiment is used to collect and store the garbage swept by the roller brush 21. By setting the garbage collection box 5, the cleaning module in this embodiment has the function of garbage collection. The garbage collection box 5 is slid into the housing 1 from the side of the housing 1 and extends in a direction parallel to the roller brush 21. With such an arrangement, it is convenient to install the garbage collection box 5. Specifically, in this embodiment, the garbage collection box 5 is located at the rear side of the housing 1. The garbage collection box 5 is a strip - shaped box body, and a box opening is provided on the side facing the roller brush 21. When the two roller brushes 21 are brushing the floor, the garbage is squeezed into the gap between the two roller brushes 21 and thrown into the garbage collection box 5.

[0045] The spraying assembly in this embodiment is arranged in the housing 1 and is used to spray liquid on the roller brush 21. By setting the spraying assembly, the cleaning module in this embodiment can moisten the roller brush 21 to achieve the function of wet floor - brushing. This cleaning module can be used for both dry and wet cleaning, and the user can use it according to specific cleaning needs. As Figure 1 and 11As shown in the figure, specifically, the spraying assembly in this embodiment includes a water inlet pipe 41 and a strip-shaped housing 42. The strip-shaped housing 42 is connected to the top inside the housing 1 and is arranged parallel to the rotary brush 21. A water tank is jointly formed between the strip-shaped housing 42 and the inner wall of the housing 1. A plurality of water spraying holes 421 are arranged on the outer wall of the strip-shaped housing 42 at equal intervals along the extending direction of the strip-shaped housing 42. One end of the water inlet pipe 41 communicates with the water tank, and the other end extends out of the top of the housing 1. When water is added through the water inlet pipe 41 (the water added here does not only refer to clean water, but can also be cleaning liquids such as cleaning solutions and disinfectants), the water enters the water tank and is evenly sprayed out from the water spraying holes 421. The sprayed water columns can evenly wet the bristles of the rotary brush 21, so that the rotary brush 21 is fully wetted to achieve a better effect of wet mopping the floor. When the cleaning module in this embodiment is installed at the bottom of the cleaning robot, the water inlet pipe 41 is communicated with the water tank of the robot, and the robot controls whether to discharge water.

[0046] In the prior art, cleaning the corner has always been a difficult point in the function implementation of cleaning robots. Therefore, the cleaning module in this embodiment is provided with the side brush assembly 3 for cleaning the garbage at the intersection of the wall and the floor, so that it has the function of cleaning the corner. As Figure 12 shown in the figure, specifically, the side brush assembly 3 includes a side brush frame 31, a side brush driving motor 32 and a disc-shaped side brush 33. The side brush frame 31 is connected to one side of the housing 1 and extends along the direction away from the housing 1. The side brush driving motor 32 is arranged at the end of the side brush frame 31 away from the housing 1. The disc-shaped side brush 33 is connected to the output shaft of the side brush driving motor 32. The side brush assembly 3 can effectively solve the problem of cleaning the corner through the extended side brush frame 31. For example, when the cleaning module in this embodiment is actually installed at the bottom of the robot, the tip of the disc-shaped side brush 33 extends 6 cm beyond the casing. Further, in order to solve the problem that the brush exceeds the housing 1 during the cleaning process and is likely to brush pedestrians near the robot, the side brush frame 31 in this embodiment is connected to the right front side of the housing 1. Since the robot travels on the right, such an arrangement can provide a certain protection for pedestrians. In addition, the side brush driving motor 32 and the rotary brush driving motor 251 in this embodiment are both brushless motors, which have the advantages of long service life, low noise and low power consumption.

[0047] The water scraping assembly 6 in this embodiment is arranged on the side of the housing 1 for scraping water on the ground to remove the water marks on the ground. The cleaning module in this embodiment is provided with the water scraping assembly 6 to enable it to have the function of scraping water on the ground. Specifically, the number of the water scraping assemblies 6 in this embodiment is two, which are respectively arranged on the left and right sides of the housing 1, as Figure 13As shown, each wiper assembly 6 includes a wiper strip 61 and a connecting bracket 62. One end of the connecting bracket 62 is connected to the housing 1 through a hinge 63, and the other end is connected to the housing 1 through a bolt member 64. The bolt member 64 is a bolt with a mushroom head, which is convenient for the user to operate without using other tools and is easy to maintain. The wiper strip 61 is connected to the bottom edge of the connecting bracket 62 and can perform the work of wiping water on the ground.

[0048] The cleaning module of the present invention has the following advantages:

[0049] 1. The roller brush unit is convenient to disassemble and assemble, facilitating the replacement of the roller brush, which is beneficial to improving work efficiency, saving working time, and enhancing the user experience.

[0050] 2. It is provided with a roller brush unit, side brush assemblies, a spraying assembly, a garbage collection box, and a wiper assembly, integrating functions such as dry floor brushing, wet floor brushing, floor sweeping, garbage collection, water wiping, and cleaning the corners.
