[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] like Figures 1 to 6 As shown, the floor brush module in this embodiment includes a housing 1, a brush head assembly 2, a driving unit 3, a first driving mechanism 4, a front scraping strip 5, a rear scraping strip 7, and a second driving mechanism 6.

[0036] In order to achieve walking, the bottom of the housing 1 is usually provided with walking wheels. Based on the support of the walking wheels, a small gap space is formed between the bottom of the housing 1 and the ground.

[0037] A dust suction channel 11 is provided inside the housing 1. The entrance of the dust suction channel 11 in this embodiment is located at the bottom of the housing 1, and can be connected to the bottom space of the housing 1, so that the dirt on the ground in the space below the housing 1 is sucked into the dust suction channel 11, and the dirt on the ground is collected. In order to improve the suction effect of the dirt on the ground and to gather and scrape the dirt on the ground, a rear scraper strip 7 is provided at the rear side of the housing 1 and extends downward corresponding to the width of the housing 1. The rear scraper strip 7 is located at the rear side of the brush head assembly 2 and the entrance of the dust suction channel 11. The rear scraper strip 7 can be made of a deformable material such as silicone, so that the rear scraper strip 7 can achieve interference contact with the ground through deformation.

[0038] Based on the gap between the bottom of the casing 1 and the ground, a dust suction port 12 facing the ground and connected to the dust suction channel 11 is formed on the front side of the bottom of the casing 1. When the floor brush module moves forward, based on the opening of the dust suction port 12, it passes through the gap between the casing 1 and the ground from the front side of the dust suction port 12 and finally reaches the dust suction channel 11 to form a suction path for dirt on the ground.

[0039] The brush head assembly 2 is rotatably connected to the housing 1, and based on the contact between the brush head assembly 2 and the ground, the dirt on the ground is cleaned. The brush head assembly 2 can adopt various brush head assembly 2 structures in the prior art, such as a cloth brush structure or a silicone roller brush structure. The drive unit 3 is connected to the brush head assembly 2 to drive the brush head assembly 2 to rotate for cleaning. The brush head assembly 2 in this embodiment includes at least two brush heads 21, and the brush heads 21 are horizontally rotatable and arranged in the housing 1. Specifically, at least two installation cavities 13 facing the ground are arranged in the width direction in the housing 1, each installation cavity 13 is connected to the dust suction channel 11, and a brush head 21 is matched in each installation cavity 13, and the brush head 21 can be horizontally rotatably embedded in the installation cavity 13. The driving unit 3 can choose to use the driving structure in the prior art, such as the driving unit 3 includes a driving source, a gear connected to the driving source, and a pulley meshing with the gear, a belt mounted on each brush head 21 and the pulley, and then the rotational drive of each brush head 21 is realized through the transmission action of the driving source, gears, pulleys, and belts.

[0040] In addition, in the present embodiment, a first driving mechanism 4 is provided for driving each brush head 21 in the assembly to be lifted and lowered, and the brush head 21 is connected to the driving end of the first driving mechanism 4. Specifically, in the present embodiment, a first driving mechanism 4 is provided corresponding to each brush head 21, and the first driving mechanism 4 is provided above the brush head 21. The first driving mechanism 4 includes a first motor 41 and a screw 42 connected to the driving end of the first motor 41, the screw 42 extends vertically, and the brush head 21 is threadedly connected to the screw 42. Of course, in order to limit the lifting range of the brush head 21, a corresponding upper limit and lower limit structure can be provided on the screw 42. When in use, based on the forward and reverse rotation of the first motor 41, the brush head 21 can be driven to rise or fall relative to the screw 42, thereby realizing the lifting and lowering drive of the brush head 21.

[0041] The front scraper strip 5 is arranged on the front side of the housing 1 so as to be able to swing up and down corresponding to the dust suction port 12, and the second driving mechanism 6 is drivingly connected to the front scraper strip 5 to drive the front scraper strip 5 to swing up and down. Specifically, the front scraper strip 5 is drivingly connected to the second driving mechanism 6 through the transmission frame 8, and the two ends of the transmission frame 8 are rotationally limited on the housing 1, and the front scraper strip 5 is fixed to the front edge of the transmission frame 8. The second driving mechanism 6 includes a second motor 61 and a swing arm 62 connected to the second motor 61, and the swing arm 62 is drivingly connected to the transmission frame 8 to drive the transmission frame 8 to rotate and swing up and down. The transmission frame 8 includes a frame body 81 arranged along the width direction of the housing 1, and the front scraper strip 5 is connected to the front edge of the frame body 81. The cross section of the front scraper strip 5 in this embodiment is an arc shape that bends forward. The two ends of the frame body 81 are rotationally connected to the housing 1 through a shaft rod 82, and the shaft rod 82 is connected to the rear edge of the frame body 81. A U-shaped fork arm 83 is inclined on the upper surface of the frame body 81, and the fork arm 83 is inclined backward from bottom to top. The swing arm 62 is connected with a driving rod 63, and the driving rod 63 is movable and limited in the fork arm 83. When working, the second motor 61 drives the swing arm 62 to rotate forward or reverse, and the corresponding swing arm 62 will push the fork arm 83 to swing up or down, thereby realizing the up and down swinging drive of the front scraper strip 5.

[0042] In addition, the bottom of the housing 1 is provided with a soft blocking strip 14 that contacts the ground at the front side of each installation cavity 13. The blocking strip 14 is arc-shaped, and there is a gap between adjacent blocking strips 14. Based on the large air volume during cleaning, the blocking strip 14 can be opened backward at a certain angle to facilitate the dirt on the ground in front of the housing 1 to enter the dust collection channel 11. At the same time, based on the function of the blocking strip 14, more dirt on the ground will enter the dust collection channel 11 through the gap between adjacent blocking strips 14. Since the gap between the blocking strips 14 is effective, the wind speed will be relatively high, which can greatly improve the cleaning power of the dirt.

[0043] The utility model also relates to a cleaning machine, comprising a fan module and the aforementioned floor brush module, wherein the fan module is arranged in the housing 1 corresponding to the dust suction channel 11. Based on the operation of the fan module, a negative pressure is formed in the dust suction channel 11, thereby achieving the suction of the cleaned dirt, concentrating the dirt in the dirt box, and realizing the centralized collection of the dirt.

[0044] When using the cleaning machine for cleaning, the user pushes the floor brush module forward or backward, and the forward and backward signals of the floor brush module will be obtained accordingly. When the floor brush module moves forward, the second drive mechanism 6 is controlled to work to drive the front scraper strip 5 to swing up, so that the dust suction port 12 is in an open state, and the fan module is controlled to work at a higher power. At this time, the blocking strip 14 will open a certain angle based on the large air volume to allow the dirt on the ground to move backward and enter the dust suction channel 11. At the same time, based on the cleaning of the dirt on the ground by the brush head 21 and the negative pressure suction effect formed by the fan module, the dirt on the ground in front of the floor brush module enters the dust suction channel 11 through the dust suction port 12. When the floor brush module moves backward, the second drive mechanism 6 is controlled to drive the front scraper strip 5 to swing down and close the dust suction port 12. Based on the shielding effect of the front scraper strip 5, large particles of dirt are prevented from flying out through the dust suction port 12, thereby ensuring the reliability of cleaning. At the same time, based on the function of the front scraper strip 5, the front scraper strip 5 scrapes away the sewage on the ground below the casing 1. The scraped sewage can enter the dust suction channel 11 based on the suction force of the fan module, avoiding the water stain problem that occurs during the backward movement of the cleaning machine.

[0045] In addition, when the cleaning machine is stopped, the cleaning machine can be controlled to automatically move forward and backward, and the problem of residual water when the machine is stopped can be solved based on the reverse action of the front scraper strip 5.

[0046] In addition, when the cleaning machine is working, the lifting and lowering drive of the brush head 21 can be realized based on the control of the brush head 21 by the first driving mechanism 4. When the first driving mechanism 4 drives the brush head 21 to descend, the brush head 21 contacts the ground, and then performs cleaning work. When the first driving mechanism 4 drives the brush head 21 to rise, a certain gap is formed between the brush head 21 and the ground, which can effectively release the hair pressed on the upper and lower parts of the plate, and then make it easier for the hair to enter the dust collection channel 11, thus solving the problem of hair entanglement and inability to release. When working, the brush head 21 is in contact with the ground based on the normal driving state of the first driving mechanism 4, and the first driving mechanism 4 drives the brush head 21 to rise according to the set time frequency to realize the release of the hair.

[0047] The floor brush module in the utility model solves the problems of hair entanglement, flying of large particles, etc. by driving the brush head assembly 2 to rise and fall, and driving the front scraper to swing up and down, and by coordinating the two states. It also solves the problem of large water stains at the back, thereby improving the user experience.

[0048] The cleaning machine that uses this floor brush module can ensure the cleaning effect of the floor while avoiding problems such as hair entanglement, large particles flying, and large water stains on the back, thereby improving the user experience.
