Description

Floor Cleaner

Technical Field

The utility model relates to the technical field of cleaning equipment, in particular to a floor cleaner.

Background technique

The floor cleaner uses a motor to drive a roller brush to wipe the floor. At the same time, the floor cleaner is also equipped with a water system to clean the roller brush, thereby cleaning the floor. In the floor cleaners sold on the market, the roller brush cleaning part is made of nylon flannel or PVA super absorbent sponge.

If nylon flannel is used for the roller brush cleaning part, the whole machine generally needs to be equipped with a high-power powerful motor to pump the sewage into the sewage tank, which has the problems of high noise and high cost of the whole machine.

If the roller brush cleaning part uses a PVA strong water-absorbing sponge, the whole machine does not need to be equipped with a high-power powerful motor. The metal strip set on the sewage tank is interfering with the PVA sponge roller brush, and the roller brush assembly continuously rotates to squeeze out the sewage; the sewage flows into the sewage tank through the mesh set on the sewage tank; the suction generated by the vacuum pump draws the sewage into the sewage tank through the pipe. However, this structure has the following problems: due to the special nature of the PVA sponge material, the sewage entering the sewage tank is prone to produce a large amount of foam; the sewage tank is set in a long strip, and the vacuum pump has less suction on the end of the sewage tank that is farther away, resulting in a very slow sewage extraction speed, foam accumulation in the sewage tank, and thus affecting the sewage separation effect of the PVA sponge; when used continuously, the residual water stains on the ground increase, and the cleaning effect decreases.

Please refer to FIG. 1 . The floor cleaner provided by the present disclosure includes a floor brush 40 and a handle 50 connected to the floor brush 40. The user can operate the floor brush 40 by holding the handle 50 to make the floor brush 40 clean the floor. The floor brush 40 includes a floor brush housing 100, a cleaning roller brush 200 and a dust collecting assembly 300. The cleaning roller brush 200 is arranged at the front end of the floor brush housing 100. The dust collecting assembly 300 includes a hair-wrapped roller brush 301 and a dust collecting box 304. The hair-wrapped roller brush 301 and the dust collecting box 304 are both arranged inside the floor brush housing 100. The hair-wrapped roller brush 301 is interference-fitted with the cleaning roller brush 200. The hair-wrapped roller brush 301 is driven by the cleaning roller brush 200 to rotate, so that the dust collecting assembly 300 can collect dirt on the cleaning roller brush 200. It should be noted that: the entangled brush 301 and the cleaning brush 200 are interference fit, and the entangled brush 301 is driven by the cleaning brush 200 to rotate, but the contact point between the entangled brush 301 and the cleaning brush 200 generates relative motion, and the rotation speeds of the two are different, so that the entangled brush 301 can clean the dirt on the cleaning brush 200. Specifically, the dirt may include hair and particles, etc. When the cleaning brush 200 drives the entangled brush 301 to rotate, on the one hand, the particles on the cleaning brush 200 are knocked down into the dust box 304 by the entangled brush 301, and on the other hand, the hair on the cleaning brush 200 is collected by the entangled brush 301 and entangled with its own bristles.

The floor brush 40 further includes a cleaning component, which is disposed on the floor brush housing 100. Specifically, the cleaning component is located behind the moving direction of the cleaning roller brush 200, and can be in the form of a roller brush or a flat mop. In a possible implementation, during the movement of the floor cleaner, the cleaning component contacts the surface to be cleaned (e.g., the floor) to wipe off the moisture remaining on the surface to be cleaned after the cleaning roller brush 200 works.

The floor brush housing 100 includes a floor brush base 106 and a floor brush upper cover 125. The floor brush base 106 has a receiving space 107 and an installation space 108. The receiving space 107 and the installation space 108 are connected through a connecting port 109, as shown in FIG15. The cleaning roller brush 200 is installed in the installation space 108, and the dust collecting assembly 300 is detachably installed in the receiving space 107. The hair-wrapped roller brush 301 passes through the connecting port 109 and is interference-fitted with the cleaning roller brush 200. The floor brush upper cover 125 covers the floor brush base 106.

The entangled brush 301 is located between the cleaning brush 200 and the dust box 304. The dust box 304 is provided with an opening 305 on one side facing the cleaning brush 200. The entangled brush 301 is located at the opening 305. When the dust box 304 is installed in the accommodating space 107, the opening 305 on the dust box 304 is connected with the connecting port 109. The entangled brush 301 rotates to sweep the solid waste on the cleaning brush 200 into the dust box 304. The lower edge 307 of the opening 305 of the dust box 304 extends into the connecting port 109 or directly abuts against the connecting port 109 to achieve connection with the connecting port 109. In the structure shown in Figure 9, the lower edge 307 of the opening 305 of the dust box 304 extends into the connecting port 109 and contacts the cleaning roller brush 200. The solid waste cleaned from the cleaning roller brush 200 by the hair-wrapped roller brush 301 can enter the dust box 304 along the lower edge 307 of the opening 305 of the dust box 304.

The opening 305 is provided at the upper part of the dust box 304, and the entangled hair roller brush 301 is located at the upper rear part of the cleaning roller brush 200. The opening 305 is provided at the upper part of the dust box 304, and the solid waste swept from the cleaning roller brush 200 can be deposited at the bottom of the dust box 304, thereby increasing the effective volume of the dust box 304. In this embodiment, the bottom depth of the dust box 304 is not less than 1/3 of the diameter of the cleaning cylinder 201.

In a possible implementation, the opening 305 is provided at the upper part of the dust box 304, and extends from a side of the dust box 304 close to the cleaning roller brush 200 to the top surface of the dust box 304, and the hair roller brush 301 is close to the lower edge 307 of the opening 305. This design enables the dust box 304 to have a larger opening 305, which is convenient for receiving the solid waste peeled off from the cleaning roller brush 200 by the hair roller brush 301, and is also convenient for the user to clean the dust box 304. In addition, since the opening 305 extends to the top of the dust box 304, an additional cover plate is required for shielding. In the structure shown in Figures 2 and 3, the top of the dust box 304 is shielded by the cover plate of the floor brush 40 to prevent the solid waste in the dust box 304 from spilling out, while maintaining an integral and beautiful appearance.

In another possible implementation, the opening 305 is provided on one side of the dust box 304 close to the cleaning roller brush 200 and located at the upper part of the dust box 304, and the top of the dust box 304 is closed. This design does not require an additional cover plate to cover the dust box 304. In the structure shown in Figures 13 and 14, a handle 306 is also provided on the top of the dust box 304. When the floor brush upper cover 125 is covered on the floor brush base 106, the top of the dust box 304 is exposed from the floor brush upper cover 125, and the user can quickly take out and put back the dust box 304 by operating the handle 306. In this structure, the dust box 304 can also be made of transparent material, which is convenient for the user to observe the internal situation of the dust box 304 from the top and dump the garbage in time.

The long axis of the cleaning roller brush 200 is consistent with the long axis direction of the hair-entangled roller brush 301. When the cleaning roller brush 200 drives the hair-entangled roller brush 301 to rotate, the rotation direction of the hair-entangled roller brush 301 is opposite to the rotation direction of the cleaning roller brush 200. In a possible implementation, the hair-entangled roller brush 301 always rotates from the position of interference fit with the cleaning roller brush 200 to the top of the dust box 304, and accordingly, the cleaning roller brush 200 rotates from the position of interference fit with the hair-entangled roller brush 301 to the top of the floor brush housing 100, and the solid garbage swept off the cleaning roller brush 200 by the hair-entangled roller brush 301 can directly enter the bottom of the dust box 304, while the hair is entangled on the hair-entangled roller brush 301, thereby reducing or avoiding the hair entangled on the cleaning roller brush 200.

The entangled hair roller brush 301 includes a rotating shaft 302 and bristles 303 arranged on the outer surface of the rotating shaft 302. The entangled hair roller brush 301 can be arranged on the floor brush housing 100, or on the dust box 304. Since both the entangled hair roller brush 301 and the dust box 304 need to be cleaned, the entangled hair roller brush 301 and the dust box 304 need to be detachable. In the structure shown in Figures 5 and 15, the entangled hair roller brush 301 is arranged on the dust box 304, and the user can take out the entangled hair roller brush 301 together when taking out the dust box 304. In a possible implementation, since the dust box 304 is provided with a sufficiently large opening 305, the entangled hair roller brush 301 will not block the opening 305, so there is no need to remove the entangled hair roller brush 301 from the dust box 304 during cleaning, which can improve the convenience of use and improve the user experience.

The cleaning roller brush 200 includes a cleaning cylinder 201 and a power device 202, and the power device 202 drives the cleaning cylinder 201 to rotate. In the structure shown in Figure 9, the power device 202 is arranged inside the cleaning cylinder 201, and the output end of the power device 202 is radially engaged with the cleaning cylinder 201. The rotation of the output end can drive the cleaning cylinder 201 to rotate. The power device can be a motor. The power device 202 is arranged in the cleaning cylinder 201, so that the space of the cleaning cylinder 201 can be fully utilized and the volume of the floor cleaner can be reduced.

In the structure shown in FIG9 , the lower edge 307 of the opening 305 of the dust box 304 contacts the cleaning cylinder 201, and a baffle 124 is provided on the lower end of the connecting arm 110 near the accommodating space 107. The baffle 124 is interference fit with the cleaning cylinder 201, and the bristles 303 are interference fit with the area of the cleaning cylinder 201 exposed between the baffle 124 and the lower edge 307. The interference between the bristles 303 and the cleaning cylinder 201 is 1.0 mm to 5.0 mm. The material of the bristles 303 is hard nylon. The interference fit between the bristles 303 and the cleaning cylinder 201 is designed to drive the hair-wrapped roller brush 301 to rotate through the cleaning cylinder 201. If the interference is too large or the bristles 303 are too hard, the friction between the cleaning cylinder 201 and the brush is large, resulting in large power loss; if the interference is too small or the bristles 303 are too soft, the bristles 303 cannot drive the rotating shaft 302 to rotate. The preferred range of the interference between the bristles 303 and the cleaning cylinder 201 is 3mm-4mm.

Since the hair-entangled roller brush 301 is driven to rotate by the cleaning cylinder 201 of the cleaning roller brush 200, the hair-entangled roller brush 301 does not need to be provided with a power device in its internal space like the cleaning cylinder 201, which is conducive to reducing the diameter of the hair-entangled roller brush 301. In this embodiment, the ratio of the diameter of the cleaning cylinder 201 to the diameter of the hair-entangled roller brush 301 is 1.2-3, the preferred ratio range is 1.5-2.5, and the preferred ratio is 2. The diameter of the hair-entangled roller brush 301 refers to the outer diameter of the rotating shaft 302 and the bristles 303 provided on the outer surface of the rotating shaft 302. In a possible implementation, the ratio of the diameter of the cleaning cylinder 201 to the diameter of the rotating shaft 302 is 3-8, and the preferred ratio range is 4.5-5. Usually garbage is collected at the bottom of the dust box 304 or entangled on the hair-wrapped roller brush 301. A brush cover 125 is arranged on the upper part of the dust box 304. The reduction in the diameter of the hair-wrapped roller brush 301 or the rotating shaft 302 is conducive to increasing the bottom depth of the dust box 304 and reserving space for the arrangement of other components.

In this embodiment, the entangled brush 301 and the dust box 304 are both arranged inside the floor brush housing 100, and are interference fit with the cleaning brush 200. When the cleaning brush 200 rotates, the entangled brush 301 rotates driven by the cleaning brush 200, thereby knocking particles on the cleaning brush 200 into the dust box 304, and collecting hair on the entangled brush 301. In the present disclosure, the entangled brush 301 is driven by the cleaning brush 200, and no additional power equipment is required, which saves costs and reduces the weight of the floor brush 40; since a power equipment is reduced, the space of the floor brush 40 is saved, and the volume of the dust box 304 can be expanded; the entangled brush 301 does not need to be connected to the power equipment, and the structure is simple, which is convenient to be taken out and cleaned from the floor brush housing 100.

Please continue to refer to Figure 9. The floor brush housing 100 also includes a sewage trough 101, a sewage extrusion piece 103 and a clean water trough 104 arranged above the cleaning roller brush 200. The clean water trough 104 is located in front of the moving direction of the floor cleaner, and the sewage trough 101 and the sewage extrusion piece 103 are located behind the moving direction of the floor cleaner. The clean water trough 104 has a water outlet 105 facing the cleaning roller brush 200, and the sewage trough 101 has a water inlet 102 facing the cleaning roller brush 200. The sewage extrusion member 103 and the water inlet hole 102 are arranged front and back, that is, the sewage extrusion member 103 is located in front of the floor cleaner in the direction of travel, and the water inlet hole 102 is located behind the floor cleaner in the direction of travel. The sewage extrusion member 103 is located between the water outlet hole 105 and the water inlet hole 102 and has an interference fit with the cleaning roller brush 200. When the cleaning roller brush 200 rotates, the liquid on the cleaning roller brush 200 is squeezed out by the sewage extrusion member 103 and enters the sewage tank 101 through the water inlet hole 102. Specifically, the travel direction of the floor cleaner refers to: after the cleaning roller brush 200 rotates, the floor cleaner moves in the direction driven only by the power device 202. For example, in Figure 9, the power device 202 drives the cleaning roller brush 201 to rotate clockwise, and the floor cleaner will move to the right. At this time, the right direction is the traveling direction; in Figure 9, the power device 202 drives the cleaning roller brush 201 to rotate counterclockwise, and the floor cleaner will move to the left. At this time, the left direction is the traveling direction.

In this embodiment, a sewage trough 101, a sewage extrusion piece 103 and a clean water trough 104 are arranged above the cleaning roller brush 200. The clean water trough 104 is located in front of the floor cleaner in the direction of travel, and the sewage trough 101 and the sewage extrusion piece 103 are located behind the floor cleaner in the direction of travel. The sewage extrusion piece 103 is located between the water outlet 105 of the clean water trough 104 and the water inlet 102 of the sewage trough 101 and is interference fit with the cleaning roller brush 200. When the cleaning roller brush 200 rotates, the clean water trough 104 sprays clean water to the cleaning roller brush 200. After absorbing water, the cleaning roller brush 200 first contacts the ground to clean the ground, and then rotates through the sewage trough 101 and the sewage extrusion piece 103. The liquid on the cleaning roller brush 200 is squeezed out by the sewage extrusion piece 103 and enters the sewage trough 101 through the water inlet hole 102 to realize sewage recovery. In this way, it can not only ensure that the surface of the cleaning cylinder 201 is adsorbed with clean water, but also the cleaning cylinder 201 can be effectively cleaned to improve the floor cleaning effect. In this embodiment, a clean water tank 104 and a dirty water tank 101 are provided independently of each other, and clean water is separated from dirty water, thereby preventing the clean water and dirty water from mixing and supplying unclean water to the cleaning roller brush, thereby affecting the cleaning effect.

The water outlet 105 of the clean water tank 104 does not contact the cleaning roller brush 200. Dirt on the cleaning roller brush 200 will not enter the water outlet 105, avoiding blockage of the water outlet 105, keeping the clean water tank 104 hygienic, and there is no need to remove the clean water tank 104 for cleaning. The interference between the sewage extrusion member 103 and the cleaning roller brush 200 is 2mm-3mm, and the preferred value of the interference is 2.5mm.

The floor cleaner also includes a clean water tank 51, a first pump, a sewage tank 53 and a second pump. The clean water tank 51, the first pump and the clean water tank 104 are connected in sequence to form a clean water path, and the sewage tank 53, the second pump and the sewage tank 101 are connected in sequence to form a sewage path. In the structure shown in FIG1 , the clean water tank 51, the first pump, the sewage tank 53 and the second pump are all arranged on the handle 50. The clean water tank 51, the sewage tank 53 and the first pump and the second pump are arranged in sequence from the grip end of the handle 50 to the floor brush 40. The first pump and the second pump are arranged side by side between the sewage tank 53 and the floor brush 40. The first pump is connected to the clean water tank 51 and the floor brush housing 100 respectively, and the clean water in the clean water tank 51 is pumped into the clean water tank 104 on the floor brush housing 100. The second pump is connected to the sewage tank 53 and the floor brush housing 100 respectively, and the sewage in the sewage tank 101 on the floor brush housing 100 is pumped into the sewage tank 53. Placing the water tank and the pump on the handle 50 can reduce the weight of the floor brush 40, making it more convenient and labor-saving for the user to operate the floor cleaner. Of course, the positions of the clean water tank 51, the sewage tank 53, the first pump, and the second pump on the handle 50 can also be changed. For example, the first pump and the second pump can also be placed on the floor brush as long as they do not affect the normal circulation of the clean water channel and the sewage channel. Among them, the first pump and the second pump can be water pumps or air pumps.

A connecting arm 110 is provided above the installation space 108 of the floor brush base 106, and the connecting arm 110 connects the side panels 111 on both sides of the floor brush base 106. The clean water trough 104 and the sewage trough 101 are arranged on the connecting arm 110. The clean water trough 104 is connected to the first pump through a clean water pipeline, and the sewage trough 101 is connected to the second pump through a sewage pipeline.

The clean water pipeline includes a clean water pipe (not shown in the figure) and a first adapter 113 arranged on the floor brush base 106, and the sewage pipeline includes a sewage pipe (not shown in the figure) and a second adapter 115 arranged on the floor brush base 106. The first adapter 113 connects the clean water pipe with the clean water tank 104, and the second adapter 115 connects the sewage pipe with the sewage tank 101. The clean water pipe and the sewage pipe are arranged on the same side or different sides of the floor brush base 106.

In a possible implementation, the second pump connected to the sewage tank 53 is an air pump, and the air inlet of the air pump is connected to the sewage tank 53, so that the sewage tank 53 generates negative pressure to suck the sewage in the sewage tank 101; the exhaust port of the air pump is connected to the sewage tank 101 to promote the flow of sewage in the sewage tank 101. To achieve the use of the gas discharged by the air pump to promote the flow of sewage in the sewage tank 101, as shown in FIG7, a gas pipeline can be provided between the exhaust port of the air pump and the sewage tank 101, and the gas pipeline includes an air pipe (not shown in the figure) provided on the floor brush base 106 and a third adapter 131, the air pipe connects the exhaust port of the air pump and the third adapter 131, and the third adapter 131 connects the air pipe and the sewage tank 101. The third adapter 131 and the second adapter 115 are respectively arranged at the two ends of the sewage tank 101. The sewage at one end of the sewage tank 101 is pushed by the gas pumped out by the air pump, and the sewage at the other end is sucked back to the sewage tank 52 by the air pump, thereby forming a better sewage flow to reduce the retention of dirt and foam carried in the sewage in the sewage tank 101, thereby reducing the cleaning frequency of the sewage tank 101.

In a possible implementation, please refer to FIG8 , the sewage pipeline further includes a sewage cache box 132, the sewage cache box 132 includes a cache chamber 133 and a diversion port 134 connected to the cache chamber 133, the diversion port 134 is connected to the sewage tank 101, and the second adapter 115 is connected to the cache chamber 133. The design of the sewage cache box 132 can prevent the sewage from being discharged in a timely manner due to a large flow of sewage, which causes the sewage in the sewage tank 101 to overflow. Specifically, the diversion port 134 can be set at the upper part of the sewage cache box 132, and the second adapter 115 can be set at the lower part of the sewage cache box 132, so that the diversion port 134 is higher than the second adapter 115, and the volume of the cache chamber is expanded. Preferably, the diversion port 134 can be set at the highest point of the sewage cache box 132, and the second adapter 115 can be set at the lowest point of the sewage cache box 132, so as to discharge the sewage in the cache chamber 133 as much as possible, and avoid long-term water accumulation in the cache chamber 133.

In this embodiment, the exhaust direction of the second pump is roughly parallel to the flow direction of the sewage in the sewage tank 101. Specifically, the sewage tank 101 is long and narrow, and the two ends of the sewage tank 101 are respectively connected to the third adapter 131 and the sewage tank 53, so the sewage flows along the long axis of the sewage tank 101. The exhaust direction of the second pump is consistent with the long axis of the sewage tank 101, so the direction in which the third adapter 131 blows toward the sewage tank 101 is consistent with the discharge direction of the sewage in the sewage tank 101, which is conducive to promoting the discharge of sewage.

The sewage extruder 103 squeezes the cleaning roller brush 200 to transfer the sewage on the cleaning roller brush 200 to the sewage tank 101. Due to the use of detergents or the material of the cleaning roller brush, foam may be generated during the sewage transfer process, so that there is not only sewage but also foam in the sewage tank 101. The accumulation of foam in the sewage tank 101 may reduce the sewage discharge speed. In this embodiment, the air outlet end of the second pump is led to the sewage tank 101, and the second pump exhausts air to the sewage tank 101, which will push the foam to flow with the sewage to the side of the sewage tank 101 connected to the sewage tank 53, thereby reducing the influence of the foam on the sewage discharge speed.

Please refer to Figures 18 and 19. The third adapter 131 includes a first pipe 135 and a second pipe 136 that are interconnected. The first pipe 135 is connected to the exhaust port of the second pump, and the second pipe 136 is connected to the sewage tank 101. The extension direction of the second pipe 136 is consistent with the long axis of the sewage tank 101. The sewage in the sewage tank 101 flows along the long axis of the sewage tank 101. The second pipe 136 guides the wind blown into the first pipe 135 so that the direction of the wind blown out from the second pipe 136 is consistent with the discharge direction of the sewage in the sewage tank 101, which can effectively promote the sewage and the foam in the sewage to flow toward the end of the sewage tank 101 connected to the sewage tank 53, reducing or avoiding the retention of sewage and foam in the sewage tank 101. In a possible implementation, the first pipe 135 and the second pipe 136 form an angle of about 90°. In other embodiments, the first pipe 135 and the second pipe 136 can form any angle, which is not limited in this application. It should be understood that here the first pipe 135 and the second pipe 136 are arranged at a certain angle to each other, so that the third adapter 131 can be arranged in the existing structure of the floor brush base 106 without changing the structure of the floor brush base 106 to accommodate the third adapter 131.

In a possible implementation, the clean water pipe is arranged along one of the side panels 111 of the floor brush base 106, and the sewage pipe is arranged along the other side panel 111 of the floor brush base 106. As shown in FIG4, the floor brush base 106 may be composed of a lower bracket 128 and an upper bracket 127, and the upper bracket 127 and the lower bracket 128 are formed separately and then assembled into the floor brush base 106. FIG6-FIG8 show the structure of the lower bracket 128, and the lower bracket 128 of the floor brush base 106 has two side panels 111 arranged opposite to each other, the front ends of the two side panels 111 are installation spaces 108, and the rear ends of the two side panels 111 are connecting panels, and the side panels 111 and the connecting panels are both double-layer panels with hollow channels 129 inside. A first adapter 113 is provided at one end of the clean water tank 104, one end of the clean water pipe is connected to the first pump, the other end of the clean water pipe passes through the handle 50 and enters the hollow channel 129 of one of the side plates 111 along the hollow channel 129 on the connecting plate, and then is connected to the first adapter 113; a second adapter 115 is provided at one end of the sewage tank 101 away from the first adapter 113, one end of the sewage pipe is connected to the second pump, the other end of the sewage pipe passes through the handle 50 and enters the hollow channel 129 of the other side plate 111 along the hollow channel 129 on the connecting plate, and then is connected to the second adapter 115. A stopper for limiting the clean water pipe and the sewage pipe is also provided in the hollow channel 129. The stopper limits the sewage pipe and the clean water pipe to prevent the pipe from shaking and causing the joint to loosen, and to prevent the pipe from hitting the inner wall of the floor brush housing 100 to generate noise.

In the structure shown in FIGS. 10 to 12 , a clean water tank installation part 116 and a sewage tank installation part 117 are arranged side by side on the connecting arm 110. The clean water tank installation part 116 has a first channel 118 connected to the installation space 108, and the sewage tank installation part 117 has a second channel 119 connected to the installation space 108. When the clean water tank 104 is installed on the clean water tank installation part 116, the water outlet 105 of the clean water tank 104 is exposed to the first channel 118. When the sewage tank installation part 117 is installed on the sewage tank installation part 117, the water inlet 102 of the sewage tank 101 is exposed to the second channel 119. In this structure, the first channel 118 does not contact the cleaning roller brush 200, so as to prevent dirt on the cleaning roller brush 200 from clogging the water outlet 105 of the clean water tank 104.

In this embodiment, the clean water tank 104 and the sewage tank 101 are both long strips, and the water outlet 105 of the clean water tank 104 and the water inlet 102 of the sewage tank 101 are both arranged along the long axis of the cleaning roller brush 200. A plurality of the water outlets 105 are arranged at intervals along the long axis of the clean water tank 104, and the water outlet range of the water outlets 105 covers the axial surface of the cleaning cylinder 201, ensuring that the surface of the cleaning cylinder 201 is evenly sprayed with clean water, and a plurality of rows of water inlet holes 102 are arranged at intervals along the vertical direction of the long axis of the sewage tank 101 on the sewage tank 101, and each row of water inlet holes 102 is arranged at intervals along the long axis of the sewage tank 101, and the water inlet holes 102 cover the axial surface of the cleaning cylinder 201, ensuring that the sewage squeezed out by the sewage extrusion member 103 on the cleaning cylinder 201 quickly enters the sewage tank 101. In a possible implementation, the first channel 118 may be a through hole corresponding one-to-one to the water outlet holes 105 , and the second channel 119 may be a through groove accommodating a plurality of water inlet holes 102 .

In the structure shown in Figures 10 and 11, the bottom of the sewage trough 101 has a water retaining portion 120 protruding toward the cleaning roller brush 200, the water retaining portion 120 and the cleaning roller brush 200 are interference fit, the sewage extrusion piece 103 is connected to the bottom of the sewage trough 101 and is located between the water retaining portion 120 and the clean water trough 104, and the water inlet hole 102 is provided in the area between the water retaining portion 120 and the sewage extrusion piece 103 on the bottom of the trough; a buffer space 121 is formed between the water retaining portion 120 and the sewage extrusion piece 103, and when the cleaning roller brush 200 rotates, the liquid squeezed out by the sewage extrusion piece 103 is confined in the buffer space 121 between the water retaining portion 120 and the sewage extrusion piece 103, and enters the sewage trough 101 through the water inlet hole 102.

The two ends of the cleaning roller brush 200 are interference fit with the two side plates 111 of the floor brush housing 100. The interference between the cleaning roller brush 200 and the side plates 111 of the floor brush housing 100 is 2.2 mm. After the sewage extrusion piece 103 squeezes the surface of the cleaning cylinder 201, the cleaning cylinder 201 is deformed, and the water retaining part 120 is interference fit with the cleaning cylinder 201. At the same time, the cleaning roller brush 200 and the side plates 111 are also interference fit, thereby blocking the sewage in the buffer space 121 and forcing the sewage to enter the sewage tank 101 along the water inlet hole 102. In addition, while the cleaning cylinder 201 is squeezed to form the buffer space 121, the part of the cleaning cylinder 201 that contacts the water retaining part 120 protrudes toward the water retaining part 120, increasing the interference between the water retaining part 120 and the cleaning cylinder 201, and improving the sealing effect.

The top notch of the sewage tank 101 is provided with a sewage tank cover 122, and the sewage tank cover 122 is sealed with the sewage tank 101. The sewage tank cover 122 can be made of soft rubber material, and the sealing of the top notch of the sewage tank 101 is achieved by extrusion deformation; the sewage tank cover 122 can also be sealed with the top notch of the sewage tank 101 by sleeve-mounting a sealing ring.

In one possible implementation, the sewage trough cover 122 is made of a transparent material. In the structure shown in FIG3 , the floor brush upper cover 125 is disassembled to expose the sewage trough cover 122 and the dust collecting assembly 300. The user can decide whether to clean the dust collecting assembly 300 based on the amount of solid waste collected in the dust box 304 and the dirtiness of the hair-wrapped roller brush 301. At the same time, the user can observe the dirtiness of the sewage trough 101 through the transparent sewage trough cover 122 to decide whether to clean the sewage trough 101.

The top notch of the clean water tank 104 is provided with a clean water tank cover plate 123, and the clean water tank cover plate 123 is sealed with the clean water tank 104. In the structure shown in FIG15 , the first adapter 113 is provided on the clean water tank cover plate 123, and the clean water pipe connects the first pump and the first adapter 113. The first pump pumps the clean water in the clean water tank 51 into the clean water tank 104, and the clean water flows into the clean water tank 104 from the top, so that the clean water is dispersed faster in the clean water tank 104 and wets the cleaning cylinder 201 more evenly.

The sewage extrusion member 103 and the sewage tank 101 are formed integrally or separately.

In the structures shown in FIGS. 9 to 12 , the sewage extrusion member 103 and the sewage tank 101 are integrally stamped and formed, and the bottom of the sewage tank 101 protrudes outward to form the sewage extrusion member 103. Continuing to refer to FIG. 12 , the part of the sewage tank 101 where the sewage extrusion member 103 is formed is also provided with the water inlet holes 102. When the sewage extrusion member 103 squeezes the cleaning cylinder 201, the squeezed sewage can also enter the sewage tank 101 through these water inlet holes 102, which can reduce the dirt deposition in this part. In a possible implementation, the water inlet hole 102 on the sewage extrusion piece 103 is arranged on a side of the sewage extrusion piece 103 close to the buffer space 121 and is connected to the buffer space 121; when the roller brush 200 rotates, the sewage extrusion piece 103 squeezes out the sewage from the roller brush 200, and the squeezed sewage enters the buffer space and enters the sewage tank 101 from each water inlet hole 102 connected to the buffer space 121. Here, by adding the water inlet hole 102 to the sewage extrusion piece 103, the flow area from the buffer space 121 to the sewage tank 101 can be increased, so that the squeezed sewage can quickly enter the sewage tank 101 and be discharged.

In the structures shown in FIGS. 15 to 17 , the sewage extrusion member 103 and the sewage tank 101 are formed separately, and the sewage extrusion member 103 is installed at the bottom of the sewage tank 101. Separately forming the sewage extrusion member 103 and the sewage tank 101 reduces the difficulty of forming the sewage tank 101, and avoids forming a deep concave area in the sewage tank 101, thereby avoiding the accumulation of dirt in the concave area, making the sewage tank 101 easier to clean.

In a possible implementation, the sewage squeezing member 103 is driven to rotate by the cleaning roller brush 200 .

In one possible implementation, two sides of the bottom of the sewage trough 101 are provided with snap-fitting notches, and two ends of the long strip of sewage extrusion piece 103 are respectively inserted into the snap-fitting notches on both sides and are rotatably connected, and the lower part of the sewage extrusion piece 103 is exposed from the snap-fitting notches. In another possible implementation, two ends of the sewage extrusion piece 103 are rotatably connected to the connecting arm or the two sides of the floor brush base, and the bottom of the sewage trough 101 is provided with a depression that matches the outer surface of the sewage extrusion piece 103, and the upper part of the sewage extrusion piece 103 is embedded in the depression of the bottom of the sewage trough 101.

In the structures shown in Figures 15 to 17, the sewage extrusion member 103 is driven to rotate by the cleaning roller brush 200. Specifically, the two sides of the bottom of the sewage tank 101 are provided with clamping notches, and the two ends of the sewage extrusion member 103 are respectively clamped into the clamping notches on both sides to achieve rotational connection, and the sewage extrusion member 103 is driven to rotate by the cleaning roller brush 200.

In the structure shown in FIGS. 15 to 17 , the clean water tank 104 is integrated with the connecting arm 110, and the baffle 124 is integrated with the sewage tank 101. When the floor brush upper cover 125 is covered on the floor brush base 106, the floor brush upper cover 125 shields the cleaning roller brush 200, the clean water tank 104 and the sewage tank 101, and the dust box 304 is exposed from the floor brush upper cover 125. The floor brush upper cover 125 is provided with a release button 126. The floor brush upper cover 125 can be removed from the floor brush base 106 by operating the release button 126, and the dust box 304 can be taken out by operating the handle 306 on the top of the dust box 304. This design allows the user to operate the dust box 304 alone without having to remove the floor brush upper cover 125 and then extract the dust box 304, thereby reducing the steps of disassembly and assembly.

In the floor cleaner provided in the present embodiment, when the cleaning roller brush 200 rolls up the hair and particulate matter, the hair-entangled roller brush 301 is driven by the cleaning roller brush 200 to rotate, and the particulate matter attached to the cleaning roller brush 200 is knocked down into the dust box 304, and the hair attached to the cleaning roller brush 200 is wound around the hair-entangled roller brush 301 to remove the solid dirt on the surface of the cleaning roller brush 200; at the same time, the clean water tank 104, the sewage extrusion member 103 and the sewage extrusion member 104 are sequentially arranged on the floor brush housing 100 along the rotation direction of the cleaning roller brush 200. The water tank 101 and the clean water tank 104 apply clean water to the cleaning roller brush 200. After absorbing water, the cleaning roller brush 200 contacts the ground to clean the ground, and then rotates through the sewage tank 101 and the sewage extrusion piece 103. The liquid on the cleaning roller brush 200 is squeezed out by the sewage extrusion piece 103 and enters the sewage tank 101, thereby cleaning the cleaning roller brush 200. This embodiment improves the cleanliness of the cleaning roller brush 200, so that when the cleaning roller brush 200 is used to clean the ground, a better cleaning effect can be achieved.

As shown in Fig. 20, the floor brush 40 further includes a hair cleaner 25 for cleaning dirt on the outer peripheral surface of the cleaning roller brush 200 or the hair-entangled roller brush 301. Here, it is explained that the cleaning roller brush 200 or the hair-entangled roller brush 301 is collectively referred to as a cleaning roller for convenience of description.

The hair cleaner 25 is arranged at the mounting hole (not shown) of the side wall of the floor brush housing 100 or the mounting hole (shown, the mounting hole 232 below) of the side wall of the dust box 304, and can contact the circumferential outer wall of the cleaning roller during the process of the cleaning roller being pulled out through the mounting hole along the pulling-out direction, so as to achieve cleaning of the cleaning roller on the basis of disassembling the cleaning roller. The pulling-out direction is: when the cleaning roller is installed on the floor brush housing 100 or the dust box 304, the direction from the end of the cleaning roller away from the mounting hole to the end of the cleaning roller close to the mounting hole is also parallel to the axis of the cleaning roller. Among them, the hair cleaner 25 includes a plurality of cleaning teeth 252, which are arranged at intervals along the circumference of the mounting hole, and are arranged at intervals around the circumference of the cleaning roller. The cleaning teeth 252 are used to contact the circumferential outer wall of the cleaning roller during the process of the cleaning roller being pulled out through the mounting hole to achieve cleaning.

Specifically, the cleaning roller can be a soft rubber roller brush, a bristle roller brush, a sponge roller brush, a soft velvet roller brush or a flannel roller brush. The surface of the soft rubber roller brush is covered with a soft rubber layer, and multiple rows or single rows of rubber convex columns can be formed on the outer peripheral surface of the soft rubber layer; the surface of the bristle roller brush is provided with a plurality of bristle bundles, and there are many ways to plant the bristle bundles, which can be arranged parallel to the axis of the roller brush or in a spiral shape; the surface of the sponge roller brush is covered with a sponge layer, and the sponge layer can be a PVA strong water-absorbing sponge, which achieves cleaning through its water absorption characteristics; the surface of the soft velvet roller brush or the flannel roller brush is provided with a soft velvet layer or flannel layer for cleaning. In addition, the cleaning roller can be a component that directly contacts the ground, or it can be other rolling bodies provided on the floor brush (described in detail below). Similarly, the hair cleaner 25 can be provided corresponding to the above-mentioned different types of cleaning rollers.

In this embodiment, as shown in FIG. 20 , the hair cleaner 25 further includes an annular body 251, which is connected to the floor brush housing 100 or the dust box 304, and the annular body 251 can be sleeved outside the cleaning roller. One end of the cleaning tooth 252 is connected to the inner side of the annular body 251, and the other end of the cleaning tooth 252 extends obliquely toward the end of the cleaning roller away from the mounting hole. The cleaning tooth 252 is arranged obliquely, so that the end of the cleaning tooth 252 can more easily pick up long strips of foreign matter such as hair or thread on the cleaning roller when it is pulled out, thereby ensuring that the long strips of foreign matter such as hair or thread are wrapped around the cleaning tooth 252, thereby improving the cleaning effect of the cleaning roller.

In order to further facilitate the cleaning teeth 252 to pick up long strips of foreign matter such as hair or thread, as shown in Figures 20 and 21, the cross-sectional area of the cleaning teeth 252 gradually decreases in the direction away from the annular body 251, so that the end of the cleaning teeth 252 that contacts the hair is a tip with a smaller cross section, which facilitates the cleaning teeth 252 to extend between the cleaning roller and the long strips of foreign matter such as hair or thread, thereby preventing the long strips of foreign matter such as hair or thread from being pulled out of the brush housing 100 or the dust box 304 with the cleaning roller. Among them, the cross section of the cleaning tooth 252 is perpendicular to the length direction of the cleaning tooth 252. As shown in Figure 21, the line from the root center to the top center of the cleaning tooth 252 is defined as the length of the cleaning tooth 252, and the line intersects with the axis b of the annular body 251. The length direction of the cleaning tooth 252 is the X direction, the section a is perpendicular to the X direction, and the section of the cleaning tooth 252 obtained by the section a is the cross section. It should be noted here that the length direction of each cleaning tooth 252 is different, and the X direction in FIG. 21 is the length direction corresponding to the cleaning tooth 252 cut off.

In this embodiment, the longitudinal section of the cleaning tooth 252 is a trapezoid, one of the bottoms of the trapezoid is connected to the annular body 251, and the other bottom of the trapezoid forms the end face of the free end of the cleaning tooth 252; the sides of the two waists of the trapezoid are inclined and extend toward the end of the cleaning roller away from the mounting hole. The longitudinal section is a section parallel to the length direction of the cleaning tooth 252 and passing through the axis b of the annular body 251. The longitudinal section is the section of the cleaning tooth 252 shown in FIG. 21.

Specifically, the cleaning tooth 252 includes a tooth portion 2521, and the tooth portion 2521 includes a first tooth side surface, a second tooth side surface, a third tooth side surface, a fourth tooth side surface and a tooth top surface. The first tooth side surface and the second tooth side surface are arranged along the axial direction of the annular body 251, and the third tooth side surface and the fourth tooth side surface are arranged along the circumferential direction of the annular body 251. One end of the first tooth side surface, the second tooth side surface, the third tooth side surface and the fourth tooth side surface are connected to the annular body 251, and the other end is connected to the tooth top surface, so that the cleaning tooth 252 is roughly a quadrangular prism structure, and the tooth top surface forms the free end of the tooth portion 2521. In order to make the end size of the cleaning tooth 252 smaller, the first tooth side surface and the second tooth side surface are both inclined to extend toward the end of the cleaning roller away from the mounting hole, and the distance between the third tooth side surface and the fourth tooth side surface gradually decreases along the radial direction of the mounting hole toward the center of the mounting hole.

In other embodiments, the cleaning teeth 252 may be in other shapes, for example, the cross-section of the cleaning teeth 252 may be circular, oval, or irregular.

In order to better hook the long strip foreign bodies such as hair or thread, in a possible implementation, the cleaning tooth 252 includes a tooth portion 2521 and a convex rib 2522 arranged at an angle, one end of the tooth portion 2521 is connected to the annular body 251, and the other end is connected to the convex rib 2522, the tooth portion 2521 extends from the inner side of the annular body 251 toward the center of the mounting hole, and is inclined toward the end of the cleaning roller away from the mounting hole. The convex rib 2522 extends from the tooth portion to the end of the cleaning roller away from the mounting hole. By providing the tooth portion 2521, the distance between the end of the cleaning tooth 252 and the surface of the cleaning roller is reduced, so that the cleaning tooth 252 can be easily extended into the long strip foreign bodies such as hair or thread to contact with them; the angle between the side of the convex rib 2522 facing the center of the mounting hole and the surface of the cleaning roller is smaller than the angle between the side of the tooth portion 2521 facing the center of the mounting hole and the surface of the cleaning roller, so that the convex rib 2522 can be more easily inserted between the long strip foreign bodies such as hair or thread and the cleaning roller, so as to improve the cleaning effect.

Optionally, as shown in FIG. 22 , the extension direction of the rib 2522 may be substantially parallel to the axis of the cleaning roller, so that long foreign objects such as hair or thread can be intercepted as the cleaning roller is pulled out.

In this embodiment, the diameter of the circular area surrounded by the free ends of the plurality of cleaning teeth 252 is slightly smaller than the outer diameter of the cleaning roller, so that the cleaning teeth 252 and the cleaning roller have a certain interference, which is beneficial to improve the cleaning effect of foreign matter. For the above-mentioned sponge roller brush, soft velvet roller brush or flannel roller brush, the interference between the cleaning teeth 252 and the cleaning roller should be set relatively small to avoid increasing the extraction resistance of the cleaning roller; for the above-mentioned soft rubber roller brush and planted hair roller brush, the interference between the cleaning teeth 252 and the cleaning roller can be set relatively large, which is beneficial to improve the cleaning effect of long foreign matter such as hair or thread wrapped around the bristles; and the soft rubber or bristle bundle has a certain flexibility and can be deformed to pass through the circular area.

In a possible embodiment, the area where the cleaning teeth 252 contact the cleaning roller has at least one edge, which can apply shear force to the foreign matter when the cleaning teeth 252 pick up the entangled long foreign matter such as hair or thread, so as to cut off the long foreign matter such as hair or thread, thereby improving the cleaning effect of the foreign matter.

In this embodiment, the cleaning roller includes at least two, specifically: at least one cleaning roller brush 200 and at least one entangled hair roller brush 301. In this embodiment, the cleaning roller brush 200 is selected as a sponge roller brush, and the entangled hair roller brush 301 is selected as a planted hair roller brush. Of course, other suitable types of roller brushes can also be selected according to actual needs. The cleaning roller brush 200 is rotatably set on the bottom surface of the floor brush housing 100, and is used to contact the surface to be cleaned (such as the ground) to clean dirt; the dust box 304 is detachably set in the floor brush housing 100, and the dust box 304 is provided with an inlet on the side facing the cleaning roller brush 200; the entangled hair roller brush 301 is rotatably set at the inlet of the dust box 304, and can abut against the cleaning roller brush 200, and is used to clean dirt on the surface to be cleaned (such as the cleaning roller brush 200).

The following is an example of a cleaning roller including a cleaning roller brush 200 and a entangled hair roller brush 301. The axes of the entangled hair roller brush 301 and the cleaning roller brush 200 are parallel, and the axial dimensions of the entangled hair roller brush 301 and the cleaning roller brush 200 can be roughly equal, so as to improve the cleaning effect of the entangled hair roller brush 301 on the cleaning roller brush 200. As shown in FIG. 23, a mounting hole 232 and a hair cleaner 25 are provided at a position corresponding to the entangled hair roller brush 301. When the entangled hair roller brush 301 is pulled out through the mounting hole 232, the circumferential outer wall of the entangled hair roller brush 301 contacts the cleaning teeth 252 on the hair cleaner 25, so as to clean the entangled hair roller brush 301.

The axis of the entangled brush 301 is parallel to the axis of the cleaning brush 200, and both are arranged along the length direction of the floor brush 40. When the floor brush 40 moves on the surface to be cleaned (e.g., the floor), the cleaning brush 200 actively rotates clockwise as shown in FIG9, and the hair, debris, and other garbage on the surface to be cleaned can adhere to the cleaning brush 200 and move with the cleaning brush 200. Because the entangled brush 301 abuts against the cleaning brush 200, the entangled brush 301 can be driven to rotate with the cleaning brush 200, that is, the entangled brush 301 is not provided with a driving device, but is driven by the cleaning brush 200 to rotate counterclockwise. It should be noted that the cleaning roller brush 200 and the entangled hair roller brush 301 are interference fit, and the entangled hair roller brush 301 is driven by the cleaning roller brush 200 to rotate, but the contact point between the cleaning roller brush 200 and the entangled hair roller brush 301 produces relative motion, and the rotation speeds of the two are different, so that the entangled hair roller brush 301 can clean the dirt on the cleaning roller brush 200. The entangled hair roller brush 301 cleans the surface of the cleaning roller brush 200, so that impurities such as hair and debris adhered to the surface of the cleaning roller brush 200 can be peeled off from the cleaning roller brush 200, and enter the dust box 304 through the entrance of the dust box 304 to achieve garbage collection. Of course, there can be multiple cleaning roller brushes 200 or entangled hair roller brushes 301, one entangled hair roller brush 301 is set corresponding to one cleaning roller brush 200, or one entangled hair roller brush 301 is set corresponding to multiple cleaning roller brushes 200, or multiple entangled hair roller brushes 301 are set corresponding to one cleaning roller brush 200, or multiple entangled hair roller brushes 301 are set corresponding to multiple cleaning roller brushes 200, all of which can be set according to actual needs. In this embodiment, the cleaning roller brush 200 is cleaned by the entangled hair roller brush 301, which can avoid the residual hair or debris on the cleaning roller brush 200. The particles affect the cleaning effect of the surface to be cleaned.

In this embodiment, as shown in FIG. 23 and FIG. 24 , the dust box 304 is detachably connected to the floor brush housing 100, and a mounting hole 232 is provided on the dust box 304, and the mounting hole 232 is located on the side wall of the dust box 304, and the hair roller brush 301 can be installed into the dust box 304 or pulled out from the dust box 304 through the mounting hole 232. The hair cleaner 25 is provided at the mounting hole 232 of the dust box 304 and at the second end of the hair roller brush 301, and is used to clean the hair roller brush 301.

In this embodiment, the entangled hair roller brush 301 and the hair cleaner 25 can be removed from the floor brush housing 100 along with the dust box 304. After that, the entangled hair roller brush 301 is pulled out of the dust box 304 through the mounting hole 232. During the pulling-out process, the entangled hair roller brush 301 passes through the hair cleaner 25. The cleaning teeth 252 on the hair cleaner 25 can hook the hair entangled on the entangled hair roller brush 301, so that the hair is separated from the entangled hair roller brush 301 and gathered on the cleaning teeth 252 or dropped into the dust box 304, thereby cleaning the entangled hair roller brush 301. This method does not require the cooperation of auxiliary tools such as a cutting knife, is easy to operate, and has a good cleaning effect; the user contacts the end of the entangled hair roller brush 301 to pull out the entangled hair roller brush 301, which will not dirty the user's hands, thereby improving the user experience.

Specifically, the hair-entangled roller brush 301 is arranged at the entrance, and correspondingly, the mounting hole 232 is arranged near the entrance. This arrangement is convenient for the hair-entangled roller brush 301 to clean the cleaning roller brush 200, and also convenient for the garbage swept by the hair-entangled roller brush 301 to fall directly into the dust box 304 from the entrance, thereby improving the garbage collection effect. The hair cleaner 25 is arranged at the second end of the hair-entangled roller brush 301, so that the hair-entangled roller brush 301 can pass through the hair cleaner 25 at all positions in the axial direction during the extraction process, thereby improving the cleaning effect of the hair-entangled roller brush 301.

To facilitate the disassembly and assembly of the dust box 304, as shown in FIG. 2 and FIG. 3, the floor brush housing 100 includes a floor brush base 106 and a floor brush upper cover 125. The top of the floor brush base 106 is provided with an opening, and the floor brush upper cover 125 is detachably connected to the floor brush base 106 to cover the opening. A mounting groove adapted to the dust box 304 is provided in the floor brush base 106, and the dust box 304 is located in the mounting groove to facilitate the removal and placement of the dust box 304. A hand grip groove and a release button 126 are provided on the floor brush upper cover 125 to facilitate the disassembly and assembly of the floor brush upper cover 125.

In order to facilitate the hair-entangled roller brush 301 to be drawn out or inserted into the mounting hole 232, the first end of the hair-entangled roller brush 301 is detachably connected to the inner wall of the dust box 304, and the second end of the hair-entangled roller brush 301 is detachably connected to the outer wall of the dust box 304 after passing through the hair cleaner 25 and the mounting hole 232. This arrangement allows one end of the hair-entangled roller brush 301 to extend out of the dust box 304, making it convenient for the user to grab and draw out or install the hair-entangled roller brush 301, and at the same time, it can ensure that the hair-entangled roller brush 301 can rotate relative to the dust box 304, so as to ensure that the cleaning function of the cleaning roller brush 200 is realized.

In this embodiment, as shown in Figures 23, 24 and 25, the annular body 251 is connected to the dust box 304, and the annular body 251 is sleeved outside the hair-entangled roller brush 301. The cleaning teeth 252 are all inclined to extend toward the first end of the hair-entangled roller brush 301, and the end of the cleaning teeth 252 that contacts the hair is a tip with a smaller cross section, which facilitates the cleaning teeth 252 to extend between the hair-entangled roller brush 301 and the hair, thereby preventing the hair from being pulled out of the dust box 304 along with the hair-entangled roller brush 301.

The tooth portion 2521 of the cleaning tooth 252 is conducive to reducing the distance between the end of the cleaning tooth 252 and the surface of the hair-wrapped roller brush 301, making it easier for the cleaning tooth 252 to extend into the hair bundle of the implanted hair and clean up the long foreign matter such as hair or thread on the hair bundle of the hair-wrapped roller brush 301; the angle between the side of the rib 2522 facing the center of the mounting hole 232 and the surface of the hair-wrapped roller brush 301 is smaller than the angle between the side of the tooth portion 2521 facing the center of the mounting hole 232 and the surface of the hair-wrapped roller brush 301, making it easier for the rib 2522 to be inserted between the hair and the hair-wrapped roller brush 301 to improve the cleaning effect. Optionally, the extension direction of the rib 2522 can be roughly parallel to the axis of the hair-wrapped roller brush 301, so that the long foreign matter such as hair or thread can be intercepted as the hair-wrapped roller brush 301 is pulled out.

In order to facilitate the replacement of the hair cleaner 25, the hair cleaner 25 is detachably mounted on the outer wall of the dust box 304, and the cleaning teeth 252 extend into the mounting hole 232 to clean the tangled hair roller brush 301 and facilitate the cleaned hair to fall into the dust box 304.

Specifically, the annular body 251 includes a sleeve 2511, the sleeve 2511 is inserted into the mounting hole 232, and the cleaning teeth 252 are connected to the inner wall of the sleeve 2511; the outer wall of the sleeve 2511 is connected with a first flange 2512, and the first flange 2512 is detachably connected to the dust box 304. By providing the first flange 2512, the contact area between the annular body 251 and the dust box 304 can be increased, thereby improving the fixing effect of the annular body 251 and the dust box 304. In this embodiment, the first flange 2512 can be fixed to the dust box 304 by a fastener, wherein the fastener is a screw. In other embodiments, the first flange 2512 can be fixed by clamping with the dust box 304 to facilitate the replacement of the hair cleaner 25.

To further improve the fixing effect of the hair cleaner 25 and the dust box 304, as shown in Figures 20 and 24, a second flange 2513 is further connected to the outer wall of the sleeve 2511, and a socket 231 is provided on the dust box 304, and the second flange 2513 is inserted into the socket 231. The cooperation between the second flange 2513 and the socket 231 can realize the positioning of the hair cleaner 25 and the dust box 304, facilitate the fastener to connect the first flange 2512 and the dust box 304, and improve the fixing effect.

In this embodiment, the first flange 2512 extends downward from the sleeve 2511, and the second flange 2513 extends upward from the sleeve 2511. The cooperation between the first flange 2512 and the second flange 2513 can improve the relative position accuracy of the hair cleaner 25 and the dust box 304, ensure the coaxiality of the sleeve 2511 and the hair-wrapping roller brush 301, avoid the sleeve 2511 from interfering with the disassembly and assembly of the hair-wrapping roller brush 301, and ensure the cleaning effect of the hair cleaner 25 on the hair-wrapping roller brush 301.

In order to ensure that the hair-wrapped roller brush 301 can rotate relative to the dust box 304 and facilitate the disassembly and assembly of the hair-wrapped roller brush 301, as shown in Figures 23 to 26, the floor brush 40 also includes a movable end cover 261, which can be detachably arranged on the outer wall of the dust box 304 and cover the mounting hole 232; the second end of the hair-wrapped roller brush 301 is rotatably connected to the movable end cover 261. When the user needs to disassemble the hair-wrapped roller brush 301, by removing the movable end cover 261, the hair-wrapped roller brush 301 can be driven to separate from the dust box 304, so that the hair-wrapped roller brush 301 can be pulled out of the mounting hole 232. The movable end cover 261 can also cover the mounting hole 232 when the hair-wrapped roller brush 301 is installed in the dust box 304, so as to prevent the garbage in the dust box 304 from spilling out from the mounting hole 232, thereby improving the user experience and ensuring the appearance.

In order to facilitate the assembly and disassembly of the movable end cover 261 and the dust box 304, a first adsorbing member is provided on the outer wall of the dust box 304, and a second adsorbing member is provided on the surface of the movable end cover 261 facing the dust box 304. The first adsorbing member and the second adsorbing member are adsorbed to fix the movable end cover 261 and the dust box 304. The movable end cover 261 and the dust box 304 are fixed by the adsorption of the first adsorbing member and the second adsorbing member, which is convenient for assembly and disassembly and has a simple structure.

In order to improve the relative position accuracy of the first adsorbent and the second adsorbent, a first positioning groove is provided on the outer wall of the dust box 304, and the first adsorbent is fixed in the first positioning groove; a second positioning groove 2612 is provided on the surface of the movable end cover 261 facing the dust box 304, and the second adsorbent is fixed in the second positioning groove 2612. The first adsorbent is fixed in position by the first positioning groove, and the second adsorbent is fixed in position by the second positioning groove 2612, so that the first adsorbent and the second adsorbent can face each other, so as to ensure the adsorption and fixing effect.

In some embodiments, only the first positioning groove may be provided on the dust box 304 , or only the second positioning groove 2612 may be provided on the movable end cover 261 , both of which can improve the fixing effect of the first adsorbent and the second adsorbent.

Further, in combination with FIG. 20 and FIG. 27, the hair cleaner 25 further includes a third flange 2514, which is located on the outside of the dust box 304. The third flange 2514 is provided with an annular flange 25141 on the side facing the dust box 304. The third flange 2514 is used to block the first positioning groove, and the annular flange 25141 is inserted into the first positioning groove to improve the blocking effect of the third flange 2514 on the first positioning groove. The first adsorbent and the second adsorbent are located on both sides of the third flange 2514. On the one hand, the first positioning groove can be blocked by the third flange 2514 to protect the first adsorbent; on the other hand, the hair cleaner 25 can be further fixed by the clamping effect of the first adsorbent and the second adsorbent to ensure the stability of the position of the hair cleaner 25.

In order to prevent the movable end cover 261 from rotating with the hair entanglement roller brush 301, as shown in FIG. 26 and FIG. 27, a positioning notch 2611 is provided on the movable end cover 261, and a positioning convex portion 253 is provided on the hair cleaner 25, and the positioning convex portion 253 is inserted into the positioning notch 2611. Through the cooperation of the positioning convex portion 253 and the positioning notch 2611, the movable end cover 261 can be prevented from rotating with the hair entanglement roller brush 301. In this embodiment, the positioning notch 2611 is provided on the circumferential edge of the movable end cover 261, and the positioning convex portion 253 is formed by extending the side wall of the sleeve 2511 in a direction away from the cleaning teeth 252, so as to simplify the structure of the hair cleaner 25.

In other embodiments, a positioning protrusion 253 is provided on the movable end cover 261 , and correspondingly, a positioning notch 2611 is provided on the hair cleaner 25 , which can also prevent the movable end cover 261 from rotating with the hair-entanglement roller brush 301 .

The floor brush 40 also includes a fixed end cap 262, which is fixedly arranged in the dust box 304, and the first end of the hair-wrapped roller brush 301 is rotatably inserted into the fixed end cap 262. Specifically, the fixed end cap 262 is arranged on the other side wall of the dust box 304 opposite to the side wall where the mounting hole 232 is located. A first rotating hole is arranged on the fixed end cap 262, and one end of the hair-wrapped roller brush 301 is inserted into the first rotating hole and rotatably cooperates with the first rotating hole. This arrangement has a simple structure, and the hair-wrapped roller brush 301 and the fixed end cap 262 are easy to disassemble and assemble.

Specifically, as shown in FIG. 28 , the hair-wrapped roller brush 301 includes a rotating shaft 302, a first rotating shaft 242, and a second rotating shaft 243. The first rotating shaft 242 is fixed to one end of the rotating shaft 302, and the first rotating shaft 242 is rotatably inserted into the first rotating hole of the fixed end cover 262. The second rotating shaft 243 is fixed to the other end of the rotating shaft 302, and the second rotating shaft 243 is rotatably connected to the movable end cover 261. The first rotating shaft 242 and the second rotating shaft 243 can be fixedly connected to the rotating shaft 302 through a thread pair. The end surface of the rotating shaft 302 is spaced apart from the inner wall of the dust box 304. The movable end cover 261 is provided with a second rotating hole, and the second rotating shaft 243 passes through the second rotating hole. The clamp is sleeved on one end of the second rotating shaft 243 that extends out of the second rotating hole. The clamp tightens the second rotating shaft 243 and abuts against the side of the movable end cover 261 that is away from the dust box 304 to fix the axial position of the second rotating shaft 243 and the movable end cover 261.

In order to better clean the hair on the hair-entangled roller brush 301, at least two ridges 247 are provided on the surface of the rotating shaft 302 in the hair-entangled roller brush 301. The ridges 247 extend along the axial direction of the rotating shaft 302, and at least two ridges 247 are arranged at intervals along the circumference of the rotating shaft 302. By providing at least two ridges 247, the hair wound on the hair-entangled roller brush 301 is supported by the ridges 247, avoiding direct contact between the hair and the surface of the rotating shaft 302, thereby facilitating the cleaning teeth 252 to extend between the hair and the rotating shaft 302, thereby picking up the hair and improving the cleaning effect of the hair-entangled roller brush 301.

Furthermore, the end of the cleaning tooth 252 is lower than the top surface height of the ridge 247. At the same time, there is a gap between the end of the cleaning tooth 252 and the surface of the rotating shaft 302 other than the ridge 247. This arrangement makes it easy for the cleaning tooth 252 to extend between the hair and the rotating shaft 302 and reduces the friction between the cleaning tooth 252 and the surface of the rotating shaft 302.

Optionally, the height of the ridge 247 is 0.3 mm-1 mm, such as 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm or 0.9 mm. The gap between the end of the cleaning tooth 252 and the surface of the rotating shaft 302 other than the ridge 247 is 0.1 mm-0.5 mm, such as 0.2 mm, 0.3 mm, 0.4 mm. However, the gap is ensured to be smaller than the height of the ridge 246, that is, the free end of the cleaning tooth 252 is ensured to be able to extend into the concave area formed between adjacent ridges 247, so as to facilitate the picking up of entangled hair. When the ridge 247 and the gap are within the above-mentioned height range, it can ensure that the hair is effectively supported and avoid direct contact between the hair and the rotating shaft 302 to facilitate the end of the cleaning tooth 252 to extend between the hair and the surface of the rotating shaft 302. It also takes into account the possible contact between the cleaning tooth 252 and the surface of the hair rolling brush 301 when the hair rolling brush 301 is pulled out laterally, so as to reduce the resistance encountered by the hair rolling brush 301 when it is pulled out.

In this embodiment, the hair-wrapped roller brush 301 is a hair-planted roller brush, that is, the rotating shaft 302 is implanted with bristles. Specifically, the bristles 303 of the hair-wrapped roller brush 301 include a first bristle assembly 244, which is arranged on the outer peripheral surface of the rotating shaft 302. The first bristle assembly 244 includes a plurality of clusters of first bristles, which can contact the cleaning roller brush 200 to clean the hair and impurities such as particles thereon.

In some embodiments, multiple clusters of first bristles can be arranged in a straight line along the axis of the rotating shaft 302, or multiple clusters of first bristles can be arranged in an S shape, or multiple clusters of first bristles can be arranged in a spiral around the axis of the rotating shaft 302, all of which can have the effect of cleaning the roller brush 200.

Furthermore, the distribution of multiple clusters of first bristles in an S-shaped or spiral arrangement allows the first bristle assembly 244 to form multiple point contacts with the cleaning roller brush 200. Compared with the line contact between the bristles and the cleaning roller brush when they are arranged in a straight line, the friction between the entangled roller brush 301 and the cleaning roller brush 200 can be reduced, ensuring that the entangled roller brush 301 cleans the debris on the cleaning roller brush 200 with reasonable contact force and contact points.

In this embodiment, the number of the first bristle assembly 244 is one. In other embodiments, the number of the first bristle assembly 244 may be at least two, and at least two first bristle assemblies 244 are arranged at intervals along the circumference of the rotating shaft 302, that is, multiple spirally arranged first bristles are formed, so that the hair is more easily wrapped around the hair wrapping roller brush 301, thereby improving the cleaning effect of the cleaning roller brush 200.

In this embodiment, the bristles 303 of the hair-entangled roller brush 301 further include a second bristle assembly 245, which includes a plurality of clusters of second bristles, which are arranged at intervals along the circumference of the rotating shaft 302, and the second bristle assembly 245 is arranged at one end of the rotating shaft 302 close to the hair cleaner 25. By providing the second bristle assembly 245, on the one hand, the friction between the hair-entangled roller brush 301 and the cleaning roller brush 200 can be appropriately increased according to actual needs; on the other hand, the hair can be prevented from contacting the second rotating shaft 243, thereby avoiding the problem that the second rotating shaft 243 or the cleaning teeth 252, resulting in the second end of the hair-entangled roller brush 301 and the movable end cover 261 being unable to rotate or being blocked due to the entanglement of hair.

In addition, when the hair-entangled roller brush 301 is pulled outward and the first end is about to be separated from the hair cleaner 25, a lot of hair has been accumulated on the second end of the hair-entangled roller brush 301 and the end of the cleaning teeth 252, so that the resistance between the hair-entangled roller brush 301 and the hair cleaner 25 is large. Therefore, the second brush assembly 245 is not provided at the end of the rotating shaft 302 away from the hair cleaner 25, which can avoid the user's effort in pulling out the hair-entangled roller brush 301, thereby improving the user experience.

In some embodiments, the bristle entanglement roller brush 301 may be provided with second bristle assemblies 245 at both ends to increase the friction between the bristle entanglement roller brush 301 and the cleaning roller brush 200 according to actual needs.

In order to prevent the hair from moving toward the first end of the hair-entangled roller brush 301 and entering the first rotating hole, the hair-entangled roller brush 301 also includes a third brush assembly 246, which is arranged at the first end of the roller brush. The third brush assembly 246 includes a plurality of clusters of third bristles, and the top of the third bristles extends obliquely toward the side wall of the dust box 304 connected to the first end of the hair-entangled roller brush 301. That is, the third bristles extend obliquely upward from the surface of the rotating shaft 302 and extend toward the fixed end cover 262 to prevent the hair from entering the first rotating hole, thereby ensuring the rotational cooperation between the first rotating shaft 242 and the first rotating hole.

In some possible implementations, the hair-entangled roller brush 301 can be set on the floor brush housing 100 outside the dust box 304. Accordingly, the hair cleaner 25 and the movable end cover 261 are set following the hair-entangled roller brush 301 to ensure that the hair-entangled roller brush 301 passes through the hair cleaner 25 at all axial positions during the extraction process to improve the cleaning of the surface of the hair-entangled roller brush 301.

In order to achieve a better cleaning effect, the present embodiment adopts a method in which the first bristles are arranged in a spiral around the axis of the rotating shaft 302. However, the bristles may be implanted on the ridge 247, and the height of the ridge 247 is relatively steep, that is, the curvature at the junction of the ridge 247 and the non-ridge changes greatly, which is very easy to cause the ridge 247 to break. In order to avoid the breakage of the ridge 247, the prior art often provides a notch on the ridge 247 to avoid the bristle implantation position, or does not implant bristles at the ridge 247 to avoid the breakage of the ridge 247. In addition, the high height of the ridge 247 will cause the hair cleaner to have a large resistance to the bristle roller 301 when the bristle roller 301 is pulled out, and the user has difficulty in disassembling and assembling the bristle roller 301, and the cleaning effect of the straight-line bristle implantation is poor.

To solve the above problems, the outer peripheral surface of the rotating shaft 302 includes an inner concave arc surface and an outer convex arc surface alternately arranged along the circumferential direction, and a convex ridge 247 is formed at the outer convex arc surface. By alternately arranging the inner concave arc surface and the outer convex arc surface, the cross-sectional profile of the rotating shaft 302 can be a curve with different curvatures, and the curvature of the curve is alternately arranged in positive and negative directions, so that the cross-sectional shape of the rotating shaft 302 is petal-shaped. In some embodiments, the absolute values of the curvatures of the inner concave arc surface and the outer convex arc surface can be equal or unequal. The structure of this rotating shaft 302 can not only form the convex ridge 247, but also make the convex ridge 247 have a relatively slow height, so that even if the bristles are implanted on the convex ridge 247, the convex ridge 247 will not be broken. In this way, the position and method of the hair planting are not restricted, and there is no need to avoid the convex ridge, and the distribution of the hair planting on the circumferential surface is more uniform. The small height of the convex ridge 247 can also reduce the resistance encountered when the hair-wrapped roller brush 301 is pulled out, so that the disassembly and assembly of the hair-wrapped roller brush 301 is more labor-saving, and the user experience is improved.

It can be understood that in the above embodiment, the floor brush 40 includes a cleaning roller brush 200 and a hair-entangled roller brush 301, which is a possible implementation method. In some other possible implementation methods, the floor brush 40 may include at least one cleaning roller brush 200 and at least one hair-entangled roller brush 301. The number of cleaning roller brushes 200 and hair-entangled roller brushes 301 can be selected and combined according to actual needs to improve the cleaning effect.

Of course, in some other possible implementations, the floor brush 40 may not be provided with the hair-entangled roller brush 301, and only include at least one cleaning roller brush 200 to clean the surface to be cleaned (such as the ground); or the cleaning roller brush 200 may not be provided, and only include at least one hair-entangled roller brush 301 to clean other surfaces to be cleaned inside the floor brush 40. These settings can be made according to actual needs.

Regardless of the number combination of the cleaning roller brush 200 and the hair entanglement roller brush 301, a corresponding hair cleaner 25 can be provided according to actual needs and structure to ensure that the cleaning roller brush 200 and/or the hair entanglement roller brush 301 are passed through the cleaning teeth 252 of the hair cleaner 25 at all axial positions during the extraction process to improve the cleaning of the surface of the cleaning roller brush 200 and/or the hair entanglement roller brush 301.
