The second air inlet channel 140, the partition 180 for separating the first air inlet channel 120 and the second air inlet channel 140, the wiper 190 located on one side of the second air inlet channel 140 and abutting against the roller brush body 300, the seal 400 located on the front side of the roller brush chamber 110 and abutting against the roller brush body 300, the sealing cavity 112 located between the roller brush body 300 and the roller brush cover plate 130 and adjacent to the seal 400, the roller 420 located on the rear side of the roller brush chamber 110, and the pair of support wheels 440 located on the rear side of the roller 420 and adjacent to the connector 200.

[0018] The roller brush cover 130 is used to partially cover the roller brush body 300 and is made of transparent material to allow observation of the degree of dirt on the roller brush body 300. The distance between the roller brush cover 130 and the roller brush body 300 ranges from 0.5 to 5 mm.

[0019] The invention also includes a water storage section 150 located between the first air inlet channel 120 and the second air inlet channel 140, a water spray hole 152 located at one end of the water storage section 150, and a temporary water storage cavity 170 located between the water storage section 150 and the scraper 190, wherein the circumferential angle between the sealing member 400 and the water spray hole 152 relative to the center of the roller brush body 300 is between 90 and 180 degrees. The scraper 190 intersects the horizontal plane at an acute angle and extends along the axial direction of the roller brush body 300, and is used to scrape away water accumulated in the bristles of the roller brush body 300. The partition 180 extends horizontally and makes the first air inlet channel 120 and the second air inlet channel 140 independently arranged. The cross-section of the temporary water storage cavity 170 is at least partially triangular. The horizontal edge of the water storage section 150 serves as a support surface for storing water, and the wiper 190 and the horizontal edge of the water storage section 150 form a temporary water storage cavity 170 with a triangular cross-section, with the opening of the temporary water storage cavity 170 facing the roller brush body 300. The part of the wiper 190 that contacts the roller brush body 300 is a comb or a scraper.

[0020] The roller brush body 300 is provided with bristles, and the seal 400 has interference fit with the bristles. The roller brush body 300, as... Figure 2 The counterclockwise rotation shown can be driven by a belt or a built-in motor. To facilitate centrifugal dehydration, the rotation speed of the roller brush 300 is preferably 1000-5000 rpm.

[0021] The bottom surfaces of the brush body 300, roller 420, and support wheel 440 are on the same horizontal plane, and the distance between the brush body 300 and roller 420 is less than the distance between roller 420 and support wheel 440. The diameter of the brush body 300 is greater than three times the diameter of roller 420 but less than six times the diameter of roller 420, and the diameter of the brush body 300 is less than the diameter of support wheel 440.

[0022] During operation, the roller brush 300 rotates counterclockwise, and cleaning fluid or water is sprayed from the spray holes 152 of the water storage section 150, wetting the bristles on the roller brush 300. Under the action of centrifugal force, some water is thrown into the temporary water storage chamber 170. When the temporary water storage chamber 170 is full, the water will fully wet the bristles on the roller brush 300. Since the temporary water storage chamber 170 is close to the second air inlet channel 140, the water on the roller brush 300 enters the second air inlet channel 140 during the counterclockwise movement of the roller brush 300, then passes through the conveying pipe 160 and the connector 200, and finally enters the wastewater tank of the cleaning device. At the same time, some dust or debris will also enter the first air inlet channel 120, then pass through the conveying pipe 160 and the connector 200, and finally enter the wastewater tank of the cleaning device.

[0023] This invention discloses a second embodiment of a cleaning device, which is preferably a floor scrubber, a wet / dry vacuum cleaner, or a carpet cleaner, etc. It includes a cleaning brush and a body connected to the cleaning brush and having a motor. The cleaning brush includes: a base 100 with a roller brush chamber 110 and a roller brush cover plate 130 at the front end; a connector 200 disposed at the rear end of the base 100 and downstream of the roller brush chamber 110; a roller brush body 300 disposed in the roller brush chamber 110; a conveying pipe 160 located between the roller brush chamber 110 and the connector 200; a first air inlet channel 120 connected to the upstream end of the conveying pipe 160 and near the bottom of the roller brush body 300; and a second air inlet channel 140 connected to the upstream end of the conveying pipe 160 and near the top of the roller brush body 300.

[0024] This embodiment also includes a detachable wastewater tank mounted on the machine body and a clean water tank adjacent to the wastewater tank.

[0025] The roller brush cover 130 is used to partially cover the roller brush body 300 and is made of transparent material to allow observation of the degree of dirt on the roller brush body 300. The distance between the roller brush cover 130 and the roller brush body 300 ranges from 0.5 to 5 mm.

[0026] The invention also includes a water storage section 150 located between the first air inlet channel 120 and the second air inlet channel 140, a spray nozzle 152 located at one end of the water storage section 150, and a temporary water storage cavity 170 located between the water storage section 150 and the scraper 190, wherein the circumferential angle between the sealing member 400 and the spray nozzle 152 relative to the center of the roller brush body 300 is between 90 and 180 degrees. To facilitate water spraying, the invention further includes a pump located downstream of the clean water tank and upstream of the water storage section 150, a control circuit for controlling the pump and motor, and a power supply for providing power to the control circuit.

[0027] The roller brush body 300 is provided with bristles, and the seal 400 has interference fit with the bristles. The roller brush body 300, as... Figure 2 The counterclockwise rotation shown can be driven by a belt or a built-in motor, with the roller brush body 300 rotating at a speed of 500-5000 revolutions per minute.

[0028] The bottom surfaces of the brush body 300, roller 420, and support wheel 440 are on the same horizontal plane, and the distance between the brush body 300 and roller 420 is less than the distance between roller 420 and support wheel 440. The diameter of the brush body 300 is greater than three times the diameter of roller 420 but less than six times the diameter of roller 420, and the diameter of the brush body 300 is less than the diameter of support wheel 440.

[0029] During operation, the roller brush 300 rotates counterclockwise, and cleaning fluid or water is sprayed from the spray holes 152 of the water storage section 150, wetting the bristles on the roller brush 300. Under the action of centrifugal force, some water is thrown into the temporary water storage chamber 170. When the temporary water storage chamber 170 is full, the water will fully wet the bristles on the roller brush 300. Since the temporary water storage chamber 170 is close to the second air inlet channel 140, the water on the roller brush 300 enters the second air inlet channel 140 during the counterclockwise movement of the roller brush 300, then passes through the conveying pipe 160 and the connector 200, and finally enters the wastewater tank of the cleaning device. At the same time, some dust or debris will also enter the first air inlet channel 120, then pass through the conveying pipe 160 and the connector 200, and finally enter the wastewater tank of the cleaning device.

[0030] Furthermore, the present invention places a sealing element 400 on the lower front side of the floor brush, which can form a relative seal with the roller brush body. After the clean water sprayed from the water spray hole 152 cleans the roller brush body, it is then thrown out by the centrifugal force of the rotating roller brush body into the sealed cavity 112 formed by the roller brush body 300 and the sealing element 400. By controlling the distance S between the roller brush body 300 and the roller brush cover plate 130 to be 0.5-5mm, the water thrown out by the centrifugal force is then vacuumed away by the motor through this tiny gap. In this way, it can be ensured that the roller brush body is dry and clean when mopping the floor, thereby ensuring the dryness and cleanliness of the floor.

[0031] The advantages of this invention are: improved user experience, reduced water accumulation on the ground, increased ground cleanliness, and reduced secondary pollution.

[0032] Of course, the above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be used to limit the scope of protection of the present invention. All equivalent transformations or modifications made according to the spirit and essence of the main technical solution of the present invention should be covered within the scope of protection of the present invention.
