Description

Floor cleaner Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and in particular to a floor cleaner. Background Art

[0002] The floor cleaner uses a motor to drive a cleaning drum to wipe the floor. The floor cleaner is also equipped with a water system to clean the cleaning drum, thereby cleaning the floor. To ensure that the garbage on the cleaning drum can be removed and placed in a trash can, a cleaning mechanism is usually installed between the cleaning drum and the trash can. The cleaning mechanism includes a cleaning power unit and a rotating shaft. The cleaning power unit drives the rotating shaft to rotate in the same direction as the cleaning drum, achieving the effect of knocking hair and dust off the cleaning drum and placing them in the trash can.

[0003] However, since the rotating shaft is driven by a driving device, the cleaning mechanism is too large, occupying the upper space of the trash bin and forcing the volume of the trash bin to be smaller; and because of the connection between the rotating shaft and the driving device, the operation of cleaning the rotating shaft is cumbersome.

[0098] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0099] Referring to FIG1 , the floor cleaner provided by the present disclosure includes a floor brush 40 and a handle 50 connected to the floor brush 40. A user can operate the floor brush 40 by gripping the handle 50 to cause the floor brush 40 to clean the floor. The floor brush 40 includes a floor brush housing 100, a cleaning roller brush 200, and a dust collection assembly 300. The cleaning roller brush 200 is disposed at the front end of the floor brush housing 100. The dust collection assembly 300 includes a tangle-coated roller brush 301 and a dust collection box 304. Both the tangle-coated roller brush 301 and the dust collection box 304 are disposed within the floor brush housing 100. The tangle-coated roller brush 301 has an interference fit with the cleaning roller brush 200. The tangle-coated roller brush 301 is driven by the cleaning roller brush 200 to rotate, thereby enabling the dust collection assembly 300 to collect dirt from the cleaning roller brush 200. It should be noted that the entangled roller brush 301 and the cleaning roller brush 200 have an interference fit, and the entangled roller brush 301 is driven to rotate by the cleaning roller brush 200. However, the contact point between the entangled roller brush 301 and the cleaning roller brush 200 generates relative motion, and the rotation speeds of the two are different, so that the entangled roller brush 301 can clean the dirt on the cleaning roller brush 200. Specifically, the dirt may include hair and particulate matter. When the cleaning roller brush 200 drives the entangled roller brush 301 to rotate, on the one hand, the particulate matter on the cleaning roller brush 200 is knocked down by the entangled roller brush 301 into the dust collection box 304, and on the other hand, the hair on the cleaning roller brush 200 is collected by the entangled roller brush 301 and entangled with its own bristles.

[0100] The floor brush 40 also includes a cleaning component, which is provided on the floor brush housing 100. Specifically, the cleaning component is located behind the cleaning roller brush 200 in the direction of travel. It can be in the form of a roller brush or a flat mop. In one possible implementation, during the movement of the floor cleaner, the cleaning component contacts the surface being cleaned (e.g., the floor) to wipe away any moisture remaining on the surface after the cleaning roller brush 200 has been used.

[0101] The floor brush housing 100 includes a floor brush base 106 and a floor brush cover 125. The floor brush base 106 has an accommodating space 107 and an installation space 108. The accommodating space 107 and the installation space 108 are connected through a connecting port 109, as shown in Figure 15. The cleaning roller brush 200 is installed in the installation space 108, and the dust collection assembly 300 is detachably installed in the accommodating space 107. The hair-wrapped roller brush 301 passes through the connecting port 109 and has an interference fit with the cleaning roller brush 200. The floor brush cover 125 covers the floor brush base 106.

[0102] The entangled roller brush 301 is located between the cleaning roller brush 200 and the dust box 304. The dust box 304 has an opening 305 on the side facing the cleaning roller brush 200, and the entangled roller brush 301 is located in the opening 305. When the dust box 304 is installed in the accommodating space 107, the opening 305 of the dust box 304 connects with the communication port 109. The entangled roller brush 301 rotates, sweeping solid waste from the cleaning roller brush 200 into the dust box 304. The lower edge 307 of the opening 305 of the dust box 304 extends into the communication port 109 or directly abuts against the communication port 109 to achieve connection with the communication 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.

[0103] The opening 305 is located at the top of the dust box 304, and the entangled brush 301 is located above and behind the cleaning brush 200. The opening 305 located at the top of the dust box 304 allows solid waste swept from the cleaning brush 200 to settle at the bottom of the dust box 304, increasing the effective volume of the dust box 304. In this embodiment, the bottom depth of the dust box 304 is no less than 1 / 3 of the diameter of the cleaning cylinder 201.

[0104] In one possible implementation, the opening 305 is provided at the top of the dust box 304 and extends from a side of the dust box 304 near the cleaning roller brush 200 to the top surface of the dust box 304, with the bristle roller brush 301 positioned near the lower edge 307 of the opening 305. This design provides the dust box 304 with a larger opening 305, making it easier to receive solid waste removed from the cleaning roller brush 200 by the bristle roller brush 301 and facilitating cleaning of the dust box 304 by the user. Furthermore, because the opening 305 extends to the top of the dust box 304, an additional cover is required to shield it. In the structures shown in Figures 2 and 3, the floor brush 40 cover shields the top of the dust box 304, preventing solid waste from spilling out while maintaining a cohesive and aesthetically pleasing appearance.

[0105] In another possible implementation, the opening 305 is provided on the side of the dust box 304 near the cleaning roller brush 200 and located at the top of the dust box 304, and the top of the dust box 304 is closed. This design does not require an additional cover to shield the dust box 304. In the structure shown in Figures 13 and 14, the top of the dust box 304 is also provided with a handle 306. When the floor brush cover 125 is closed on the floor brush base 106, the top of the dust box 304 is exposed from the floor brush cover 125. The user can quickly remove and replace the dust box 304 by operating the handle 306. In this structure, the dust box 304 can also be made of a transparent material, making it convenient for the user to observe the interior of the dust box 304 from the top and dump garbage in a timely manner.

[0106] The long axis of the cleaning roller brush 200 is aligned with the long axis of the hair-wrapped roller brush 301. When the cleaning roller brush 200 drives the hair-wrapped roller brush 301 to rotate, the rotation direction of the hair-wrapped roller brush 301 is opposite to that of the cleaning roller brush 200. In one possible implementation, the hair-wrapped roller brush 301 always rotates from the position where it has an interference fit with the cleaning roller brush 200 toward the top of the dust box 304. Correspondingly, the cleaning roller brush 200 rotates from the position where it has an interference fit with the hair-wrapped roller brush 301 toward the top of the floor brush housing 100. The solid waste swept off the cleaning roller brush 200 by the hair-wrapped roller brush 301 can directly enter the bottom of the dust box 304, while the hair is entangled on the hair-wrapped roller brush 301, thereby reducing or preventing the hair from being entangled on the cleaning roller brush 200.

[0107] The entangled brush 301 includes a rotating shaft 302 and bristles 303 provided on the outer surface of the rotating shaft 302. The entangled brush 301 can be provided on the floor brush housing 100, or on the dust box 304. Since both the entangled brush 301 and the dust box 304 need to be cleaned, both the entangled brush 301 and the dust box 304 need to be detachable. In the structure shown in Figures 5 and 15, the entangled brush 301 is provided on the dust box 304, and the user can take the entangled brush 301 out 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 brush 301 will not block the opening 305, so there is no need to remove the entangled brush 301 from the dust box 304 when cleaning, which can improve the convenience of use and enhance the user experience.

[0108] The cleaning roller brush 200 includes a cleaning barrel 201 and a power unit 202, which drives the cleaning barrel 201 to rotate. In the structure shown in Figure 9, the power unit 202 is disposed inside the cleaning barrel 201. The output end of the power unit 202 is radially engaged with the cleaning barrel 201, and rotation of the output end drives the cleaning barrel 201 to rotate. The power unit 202 can be a motor. Placing the power unit 202 inside the cleaning barrel 201 fully utilizes the space within the cleaning barrel 201, reducing the size of the floor cleaner.

[0109] In the structure shown in FIG9 , the lower edge 307 of the opening 305 of the dust collection box 304 contacts the cleaning cylinder 201. A baffle 124 is provided at the lower end of the connecting arm 110, near the accommodating space 107. The baffle 124 has an interference fit with the cleaning cylinder 201, and the bristles 303 have an interference fit with the area of ​​the cleaning cylinder 201 exposed between the baffle 124 and the lower edge 307. The interference fit between the bristles 303 and the cleaning cylinder 201 is 1.0 mm to 5.0 mm. The bristles 303 are made of hard nylon. The interference fit between the bristles 303 and the cleaning cylinder 201 is designed to drive the rotation of the bristle roller 301 through the cleaning cylinder 201. If the interference fit is too large or the bristles 303 are too hard, friction between the cleaning cylinder 201 and the brush will be large, resulting in significant power loss. If the interference fit is too small or the bristles 303 are too soft, the bristles 303 will not be able to drive the rotation shaft 302. The preferred range of interference fit between the bristles 303 and the cleaning cylinder 201 is 3mm-4mm.

[0110] Because the entangled brush 301 is rotated by the cleaning cylinder 201 of the cleaning roller brush 200, the entangled brush 301 does not need to be equipped with a power device in its internal space, as is the case with the cleaning cylinder 201. This helps to reduce the diameter of the entangled brush 301. In this embodiment, the ratio of the diameter of the cleaning cylinder 201 to the diameter of the entangled brush 301 is 1.2-3, with a preferred ratio range of 1.5-2.5, and a preferred ratio of 2. The diameter of the entangled 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 one possible implementation, the ratio of the diameter of the cleaning cylinder 201 to the diameter of the rotating shaft 302 is 3-8, with a preferred ratio range of 4.5-5. Usually garbage is collected at the bottom of the dust box 304 or wrapped around the bristle 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 bristle 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.

[0111] In this embodiment, the entangled brush 301 and the dust box 304 are both located inside the floor brush housing 100 and have an interference fit with the cleaning brush 200. When the cleaning brush 200 rotates, the entangled brush 301 is driven by the cleaning brush 200 to rotate, 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, eliminating the need for an additional power device, saving costs and reducing the weight of the floor brush 40. Since a power device is removed, space is saved for the floor brush 40, which in turn allows for an increased capacity of the dust box 304. The entangled brush 301 does not need to be connected to a power device, resulting in a simple structure and easy removal from the floor brush housing 100 for cleaning.

[0112] 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 provided above the cleaning roller brush 200. The clean water trough 104 is located in front of the traveling direction of the floor cleaner, and the sewage trough 101 and the sewage extrusion piece 103 are located behind the traveling 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 is arranged in a front-to-rear relationship with the water inlet 102, i.e., the sewage extrusion member 103 is located in front of the floor cleaner in the direction of travel, and the water inlet 102 is located behind the floor cleaner in the direction of travel. The sewage extrusion member 103 is located between the water outlet 105 and the water inlet 102 and has an interference fit with the cleaning roller brush 200. When the cleaning roller brush 200 rotates, 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 102. Specifically, the direction of travel of the floor cleaner refers to the direction of movement of the floor cleaner after the cleaning roller brush 200 rotates, driven solely 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 direction of travel; 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 direction of travel.

[0113] 102 and the cleaning roller 200 are connected. In this embodiment, a clean water tank 104 and a sewage tank 101 are provided independently of each other, and clean water is separated from sewage, thereby preventing the clean water and sewage from mixing and supplying unclean water to the cleaning roller brush, thereby affecting the cleaning effect.

[0114] The outlet hole 105 of the clean water tank 104 does not contact the cleaning roller brush 200. Dirt on the cleaning roller brush 200 does not enter the outlet hole 105, preventing blockage of the outlet hole 105 and maintaining a clean water tank 104. Cleaning the clean water tank 104 does not require removal. The interference fit between the sewage extrusion member 103 and the cleaning roller brush 200 is 2mm-3mm, with a preferred interference fit of 2.5mm.

[0115] The floor cleaner also includes a clean water tank 51, a first pump, a dirty water tank 53, and a second pump. The clean water tank 51, the first pump, and the clean water trough 104 are sequentially connected to form a clean water circuit, while the dirty water tank 53, the second pump, and the dirty water trough 101 are sequentially connected to form a dirty water circuit. In the structure shown in FIG1 , the clean water tank 51, the first pump, the dirty water tank 53, and the second pump are all disposed on the handle 50. From the grip end of the handle 50 toward the floor brush 40, the clean water tank 51, the dirty water tank 53, the first pump, and the second pump are sequentially arranged. The first pump and the second pump are disposed side by side between the dirty water 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 pumps clean water in the clean water tank 51 into the clean water trough 104 on the floor brush housing 100. The second pump is connected to the dirty water tank 53 and the floor brush housing 100, respectively, and pumps dirty water in the dirty water trough 101 on the floor brush housing 100 into the dirty water tank 53. Placing the water tank and pump on the handle 50 reduces the weight of the floor brush 40, making it easier and less labor-intensive for the user to operate the floor cleaner. Of course, the positions of the fresh water tank 51, the sewage tank 53, the first pump, and the second pump on the handle 50 can also be varied. For example, the first and second pumps can also be located on the floor brush, as long as they do not affect the normal flow of the fresh water and sewage waterways. The first and second pumps can be water pumps or air pumps.

[0116] There is a connecting arm 110 above the installation space 108 of the floor brush base 106, which 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.

[0117] The clean water pipeline includes a clean water pipe (not shown in the figure) and a first adapter 113 provided on the floor brush base 106, and the sewage pipeline includes a sewage pipe (not shown in the figure) and a second adapter 115 provided on the floor brush base 106. The first adapter 113 connects the clean water pipe with the clean water trough 104, and the second adapter 115 connects the sewage pipe with the sewage trough 101. The clean water pipe and the sewage pipe are provided on the same side or different sides of the floor brush base 106.

[0118] In one possible implementation, the second pump connected to the sewage tank 53 is an air pump. 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 from the sewage tank 101. The exhaust port of the air pump can be connected to the atmosphere through the exhaust hole 130 provided on the floor brush base 106, as shown in FIG18 , or the exhaust port of the air pump can be connected to the sewage tank 101 to promote the flow of sewage in the sewage tank 101, as shown in FIG19 . To achieve the purpose of using the gas discharged from the air pump to promote the flow of sewage in the sewage tank 101, as shown in FIG19 , a gas pipeline can be provided between the exhaust port of the air pump and the sewage tank 101. The gas pipeline includes an air pipe (not shown) 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 53 by the air pump, thereby forming a better sewage flow to reduce the retention of dirt carried in the sewage in the sewage tank 101 and reduce the cleaning frequency of the sewage tank 101.

[0119] 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 elongated, with the third adapter 131 and the sewage tank 53 connected at both ends, respectively, so that the sewage flows along the long axis of the sewage tank 101. Since the exhaust direction of the second pump is aligned with the long axis of the sewage tank 101, the direction of the air blown into the sewage tank 101 by the third adapter 131 is aligned with the direction of sewage discharge from the sewage tank 101, which facilitates the discharge of sewage.

[0120] The sewage extruder 103 squeezes the cleaning roller brush 200, transferring the sewage from the cleaning roller brush 200 into the sewage tank 101. Due to the detergent used or the material of the cleaning roller brush, foam may be generated during the sewage transfer process, resulting in 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 rate. In this embodiment, the air outlet of the second pump is directed to the sewage tank 101. The second pump exhausts air into the sewage tank 101, pushing the foam along with the sewage to the side of the sewage tank 101 connected to the sewage tank 53, thereby reducing the impact of foam on the sewage discharge rate.

[0121] Referring to Figures 21 and 22 , the third adapter 131 includes a first pipe 135 and a second pipe 136 that communicate with each other. The first pipe 135 connects to the exhaust port of the second pump, and the second pipe 136 connects to the sewage tank 101. The second pipe 136 extends in the same direction as the long axis of the sewage tank 101. The sewage in the sewage tank 101 flows along the long axis of the tank 101. The second pipe 136 directs the air blown into the first pipe 135 so that the direction of the air blown out from the second pipe 136 aligns with the direction of sewage discharge from the sewage tank 101. This effectively propels the sewage and foam in the sewage toward the end of the sewage tank 101 that connects to the sewage tank 53, reducing or preventing the stagnation of sewage and foam in the sewage tank 101. In one possible implementation, the first pipe 135 and the second pipe 136 form an angle of approximately 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 set to form a certain angle with each other, so that the third adapter 131 can be arranged in the existing structure of the floor brush base 106 without having to change the structure of the floor brush base 106 to accommodate the third adapter 131.

[0122] Furthermore, referring to Figure 20 , the sewage pipeline may also include a sewage buffer box 132. The sewage buffer box 132 includes a buffer chamber 133 and a diversion port 134 connected to the buffer chamber 133. The diversion port 134 connects to the sewage tank 101, and the second adapter 115 connects to the buffer chamber 133. The design of the sewage buffer box 132 can prevent the delayed discharge of large amounts of sewage, which could lead to overflow from the sewage tank 101. Specifically, the diversion port 134 can be located at the top of the sewage buffer box 132, and the second adapter 115 can be located at the bottom of the sewage buffer box 132, so that the diversion port 134 is higher than the second adapter 115, thereby increasing the volume of the buffer chamber. Preferably, the diversion port 134 can be located at the highest point of the sewage buffer box 132, and the second adapter 115 can be located at the lowest point of the sewage buffer box 132, to drain the sewage in the buffer chamber 133 as much as possible and prevent long-term water accumulation in the buffer chamber 133.

[0123] In one 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 can be composed of a lower bracket 128 and an upper bracket 127. The upper bracket 127 and the lower bracket 128 are formed separately and then assembled into the floor brush base 106. FIG6 to FIG8 show the structure of the lower bracket 128. 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. Both the side panels 111 and the connecting panels are 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, and the other end of the clean water pipe passes through the handle 50 and follows the hollow channel 129 on the connecting plate into the hollow channel 129 of one of the side panels 111, and then connects to the first adapter 113. A second adapter 115 is provided at the end of the sewage tank 101 away from the first adapter 113. One end of the sewage pipe is connected to the second pump, and the other end of the sewage pipe passes through the handle 50 and follows the hollow channel 129 on the connecting plate into the hollow channel 129 of the other side panel 111, and then connects to the second adapter 115. A stopper is also provided within the hollow channel 129 for limiting the position of the clean water pipe and sewage pipe. The stopper prevents the pipes from shaking and causing the joints to loosen, and prevents the pipes from hitting the inner wall of the floor brush housing 100 and generating noise.

[0124] In the structure shown in Figures 10-12, the connecting arm 110 is provided with a clean water trough mounting portion 116 and a sewage trough mounting portion 117 side by side. The clean water trough mounting portion 116 has a first channel 118 connected to the mounting space 108, and the sewage trough mounting portion 117 has a second channel 119 connected to the mounting space 108. When the clean water trough 104 is mounted on the clean water trough mounting portion 116, the water outlet 105 of the clean water trough 104 is exposed to the first channel 118. When the sewage trough mounting portion 117 is mounted on the sewage trough mounting portion 117, the water inlet 102 of the sewage trough 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 trough 104.

[0125] In this embodiment, the clean water trough 104 and the sewage trough 101 are both long strips, and the water outlet 105 of the clean water trough 104 and the water inlet 102 of the sewage trough 101 are both arranged along the long axis of the cleaning roller brush 200. A plurality of the water outlet holes 105 are arranged at intervals along the long axis of the clean water trough 104, and the water outlet range of the water outlet holes 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. A plurality of rows of water inlet holes 102 are arranged at intervals along the long axis of the sewage trough 101, and each row of water inlet holes 102 is provided with a plurality of water inlet holes 102 at intervals along the long axis of the sewage trough 101, and the water inlet holes 102 cover the axial surface of the cleaning cylinder 201, ensuring that the sewage squeezed out of the cleaning cylinder 201 by the sewage extrusion member 103 quickly enters the sewage trough 101. In a possible implementation, the first channels 118 may be through holes corresponding one-to-one to the water outlet holes 105 , and the second channels 119 may be through grooves for accommodating a plurality of water inlet holes 102 .

[0126] 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, and the water retaining portion 120 is interference fit with the cleaning roller brush 200. 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. 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. 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.

[0127] 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 fit 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 portion 120 is interference fit with the cleaning cylinder 201. At the same time, the cleaning roller brush 200 is also interference fit with the side plates 111, 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 is in contact with the water retaining portion 120 protrudes toward the water retaining portion 120, increasing the interference fit between the water retaining portion 120 and the cleaning cylinder 201 and improving the sealing effect.

[0128] The top notch of the sewage tank 101 is provided with a sewage tank cover 122, which is sealed with the sewage tank 101. The sewage tank cover 122 can be made of soft rubber material and seals the top notch of the sewage tank 101 by extrusion and deformation; the sewage tank cover 122 can also be sealed with the top notch of the sewage tank 101 by being provided with a sealing ring.

[0129] In one possible implementation, the sewage trough cover 122 is made of a transparent material. In the structure shown in Figure 3, the floor brush cover 125 is removed 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 bristle 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.

[0130] The top notch of the clean water tank 104 is provided with a clean water tank cover 123, which is sealed against the clean water tank 104. In the structure shown in FIG15 , a first adapter 113 is provided on the clean water tank cover 123, and a clean water pipe is connected to a first pump and the first adapter 113. The first pump pumps clean water from 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 more quickly in the clean water tank 104 and wets the cleaning cylinder 201 more evenly.

[0131] The sewage extrusion member 103 and the sewage tank 101 are formed integrally or separately.

[0132] In the structure shown in Figure 12, the sewage extrusion member 103 is integrally stamped and formed with the sewage trough 101. The bottom of the sewage trough 101 protrudes outward to form the sewage extrusion member 103. Continuing with Figure 12, the portion of the sewage trough 101 forming the sewage extrusion member 103 is also provided with the water inlet holes 102. When the sewage extrusion member 103 squeezes the cleaning cylinder 201, the extruded sewage can also enter the sewage trough 101 through these water inlet holes 102, thereby reducing dirt deposition in this area. In one possible implementation, the water inlet 102 on the sewage extrusion member 103 is provided on a side of the sewage extrusion member 103 close to the buffer space 121 and is connected to the buffer space 121; when the roller brush 200 rotates, the sewage extrusion member 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 member 103, the flow area between the buffer space 121 and the sewage tank 101 can be increased, so that the squeezed sewage can quickly enter the sewage tank 101 and be discharged.

[0133] In the structure shown in Figures 15-17, the sewage extrusion member 103 and the sewage trough 101 are formed separately, and the sewage extrusion member 103 is installed at the bottom of the sewage trough 101. Separately forming the sewage extrusion member 103 and the sewage trough 101 reduces the difficulty of forming the sewage trough 101 and avoids forming a deep recessed area in the sewage trough 101, thereby preventing dirt from accumulating in the recessed area and making the sewage trough 101 easier to clean.

[0134] In a possible implementation, the sewage extruder 103 is driven to rotate by the cleaning roller brush 200 .

[0135] In one possible implementation, two sides of the bottom of the sewage trough 101 are provided with snap-fitting notches, and the two ends of the elongated sewage extrusion member 103 are respectively snapped into the snap-fitting notches on both sides and rotatably connected, with the lower portion of the sewage extrusion member 103 exposed from the snap-fitting notches. In another possible implementation, the two ends of the sewage extrusion member 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 recess that mates with the outer surface of the sewage extrusion member 103, and the upper portion of the sewage extrusion member 103 is embedded in the recess in the bottom of the sewage trough 101.

[0136] In the structure shown in FIG17 , the clean water trough 104 is integrated with the connecting arm 110, and the baffle 124 is integrated with the sewage trough 101. When the floor brush cover 125 is closed on the floor brush base 106, it shields the cleaning roller 200, the clean water trough 104, and the sewage trough 101, while the dust box 304 is exposed from the floor brush cover 125. The floor brush cover 125 is provided with a release button 126, which can be operated to remove the floor brush cover 125 from the floor brush base 106. The dust box 304 can be removed by operating the handle 306 on the top of the dust box 304. This design allows the user to operate the dust box 304 independently without having to remove the floor brush cover 125 and then extract the dust box 304, thus reducing the number of disassembly and assembly steps.

[0137] In the floor cleaner provided by this embodiment, when the cleaning roller brush 200 rolls up hair and particulate matter, the hair-wrapped 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 collection box 304, and the hair attached to the cleaning roller brush 200 is wound around the hair-wrapped roller brush 301 to remove solid dirt on the surface of the cleaning roller brush 200; at the same time, a clean water tank 104, a sewage extrusion piece 103 and a sewage extrusion piece 104 are sequentially provided on the floor brush housing 100 in the direction of rotation of the cleaning roller brush 200. The water trough 101 and the clean water trough 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 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, 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.

[0138] As shown in Figure 23, the floor brush 40 further includes a hair cleaner 25 for cleaning dirt on the outer circumference of the cleaning roller brush 200 or the entangled hair roller brush 301. Herein, it is explained that the cleaning roller brush 200 or the entangled hair roller brush 301 will be collectively referred to as a cleaning roller for convenience of description.

[0139] The hair cleaner 25 is arranged at a mounting hole (not shown) on the side wall of the floor brush housing 100 or a mounting hole (shown as mounting hole 232 below) on the side wall of the dust box 304, and is capable of contacting the circumferential outer wall of the cleaning roller during the process of the cleaning roller being pulled out through the mounting hole in the withdrawal direction, so as to achieve cleaning of the cleaning roller on the basis of disassembling the cleaning roller. The withdrawal direction is: when the cleaning roller is installed on the floor brush housing 100 or the dust box 304, it points from the end of the cleaning roller away from the mounting hole to the end of the cleaning roller close to the mounting hole, and the direction is also parallel to the axis of the cleaning roller. 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.

[0140] 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 velvet roller brush. The surface of the soft rubber roller brush is covered with a soft rubber layer, and the outer peripheral surface of the soft rubber layer can be formed with multiple rows or single rows of rubber convex columns; the surface of the bristle roller brush is provided with a number of bristle bundles, and there are various 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, which can be a PVA strong water-absorbing sponge, and cleaning is achieved through its water absorption properties; the surface of the soft velvet roller brush or the velvet roller brush is provided with a soft velvet layer or velvet 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.

[0141] In this embodiment, as shown in Figure 23, the hair cleaner 25 also 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 mounted on the outside of 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 at an angle, so that the end of the cleaning tooth 252 can more easily pick up long foreign objects such as hair or thread on the cleaning roller when it is pulled out, thereby ensuring that long foreign objects such as hair or thread are wrapped around the cleaning tooth 252, thereby improving the cleaning effect on the cleaning roller.

[0142] To further facilitate the cleaning teeth 252 in picking up long foreign objects such as hair or thread, as shown in Figures 23 and 24, 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 foreign objects such as hair or thread, thereby preventing the long foreign objects such as hair or thread from being pulled out of the brush housing 100 or the dust collection box 304 along with the cleaning roller. Among them, the cross-sectional area of ​​the cleaning teeth 252 is perpendicular to the length direction of the cleaning teeth 252. As shown in Figure 24, the line connecting the center of the tooth root to the center of the tooth tip 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, and the cross section a is perpendicular to the X direction. The cross section of the cleaning tooth 252 obtained by cutting the cross 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 Figure 24 is the length direction corresponding to the cleaning tooth 252.

[0143] In this embodiment, the cleaning tooth 252 has a trapezoidal longitudinal cross-section. One base of the trapezoid is connected to the annular body 251, while the other base forms the end surface of the free end of the cleaning tooth 252. Both sides of the trapezoid, including the waist, extend obliquely toward the end of the cleaning roller away from the mounting hole. A longitudinal cross-section is a section parallel to the length of the cleaning tooth 252 and passing through the axis b of the annular body 251. This longitudinal cross-section is the cross-section of the cleaning tooth 252 shown in Figure 24.

[0144] Specifically, the cleaning tooth 252 includes a tooth portion 2521, and the tooth portion 2521 includes a first tooth flank, a second tooth flank, a third tooth flank, a fourth tooth flank, and a tooth top surface. The first tooth flank and the second tooth flank are arranged along the axial direction of the annular body 251, and the third tooth flank and the fourth tooth flank are arranged along the circumferential direction of the annular body 251. One end of the first tooth flank, the second tooth flank, the third tooth flank, and the fourth tooth flank 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 flank and the second tooth flank are both inclined and extended toward the end of the cleaning roller away from the mounting hole, and the distance between the third tooth flank and the fourth tooth flank gradually decreases along the radial direction of the mounting hole toward the center of the mounting hole.

[0145] 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.

[0146] To better capture long foreign objects such as hair or thread, in one possible implementation, the cleaning teeth 252 include a tooth portion 2521 and a 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 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 angled toward the end of the cleaning roller away from the mounting hole. The rib 2522 extends from the tooth portion toward the end of the cleaning roller away from the mounting hole. The provision of the tooth portion 2521 reduces the distance between the end of the cleaning tooth 252 and the surface of the cleaning roller, making it easier for the cleaning tooth 252 to reach and contact long foreign objects such as hair or thread. The angle between the side of the 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, making it easier for the rib 2522 to penetrate between the long foreign objects such as hair or thread and the cleaning roller, thereby improving the cleaning effect.

[0147] Optionally, as shown in FIG. 25 , the extension direction of the rib 2522 may be substantially parallel to the axis of the cleaning roller, so as to intercept long foreign objects such as hair or thread as the cleaning roller is withdrawn.

[0148] In this embodiment, the diameter of the circular area enclosed 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 have a certain interference fit with the cleaning roller, which is beneficial to improving the cleaning effect of foreign matter. For the sponge roller brush, soft velvet roller brush or flannel roller brush mentioned above, the interference fit 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 soft rubber roller brush and planted bristle roller brush mentioned above, the interference fit between the cleaning teeth 252 and the cleaning roller can be set relatively large to improve the cleaning effect of long foreign matter such as hair or thread wrapped around the bristles; and the soft rubber or bristle bundles have a certain flexibility and can be deformed to pass through the circular area.

[0149] In one 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.

[0150] 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).

[0151] The following description uses the cleaning roller as an example, comprising a cleaning brush 200 and a tangled brush 301. The axes of the tangled brush 301 and the cleaning brush 200 are parallel, and the axial dimensions of the tangled brush 301 and the cleaning brush 200 can be roughly equal, to improve the cleaning effect of the tangled brush 301 on the cleaning brush 200. As shown in FIG26 , a mounting hole 232 and a hair cleaner 25 are provided at positions corresponding to the tangled brush 301. When the tangled brush 301 is withdrawn through the mounting hole 232, the circumferential outer wall of the tangled brush 301 contacts the cleaning teeth 252 on the hair cleaner 25, thereby cleaning the tangled brush 301.

[0152] The axis of the entangled roller brush 301 is parallel to that of the cleaning roller brush 200, and both are arranged along the length of the floor brush 40. As the floor brush 40 moves across the surface to be cleaned (e.g., the floor), the cleaning roller brush 200 actively rotates clockwise as shown in Figure 9. Hair, debris, and other debris on the surface to be cleaned adhere to the cleaning roller brush 200 and move with it. Because the entangled roller brush 301 abuts the cleaning roller brush 200, it rotates with it. In other words, the entangled roller brush 301 does not have a drive device, but is driven counterclockwise by the cleaning roller brush 200. It should be noted that the cleaning roller brush 200 and the entangled brush 301 have an interference fit, and the entangled brush 301 is driven by the cleaning roller brush 200 to rotate. However, the contact points between the cleaning roller brush 200 and the entangled brush 301 produce relative motion, resulting in different rotational speeds. This allows the entangled brush 301 to clean dirt from the cleaning roller brush 200. The entangled brush 301 cleans the surface of the cleaning roller brush 200, allowing impurities such as hair and debris adhered to the surface of the cleaning roller brush 200 to be peeled off the cleaning roller brush 200 and enter the dust collection box 304 through the inlet, thereby achieving garbage collection. Of course, there can be multiple cleaning roller brushes 200 or entangled hair roller brushes 301, with one entangled hair roller brush 301 corresponding to one cleaning roller brush 200, or one entangled hair roller brush 301 corresponding to multiple cleaning roller brushes 200, or multiple entangled hair roller brushes 301 corresponding to one cleaning roller brush 200, or multiple entangled hair roller brushes 301 corresponding to multiple cleaning roller brushes 200, all of which can be arranged according to actual needs. In this embodiment, the entangled hair roller brush 301 is used to clean the cleaning roller brush 200, which can prevent the residual hair, debris, and other particles on the cleaning roller brush 200 from affecting the cleaning effect of the surface to be cleaned.

[0153] In this embodiment, as shown in Figures 26 and 27, the dust box 304 is detachably connected to the floor brush housing 100. The dust box 304 is provided with a mounting hole 232 located on the side wall of the dust box 304. The entangled hair roller brush 301 can be installed into or removed 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 entangled hair roller brush 301 for cleaning the entangled hair roller brush 301.

[0154] In this embodiment, the entangled brush 301 and the hair cleaner 25 can be removed from the floor brush housing 100 along with the dust box 304. Afterwards, the entangled brush 301 is pulled out of the dust box 304 through the mounting hole 232. During the pulling-out process, the entangled 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 brush 301, causing the hair to separate from the entangled brush 301 and gather on the cleaning teeth 252 or fall into the dust box 304, thereby cleaning the entangled brush 301. This method does not require auxiliary tools such as a cutting knife, is easy to operate, and has a good cleaning effect. The user touches the end of the entangled brush 301 to pull out the entangled brush 301 without dirtying the user's hands, thereby improving the user experience.

[0155] Specifically, the entangled brush 301 is positioned at the entrance, and correspondingly, the mounting hole 232 is positioned near the entrance. This arrangement not only facilitates the entangled brush 301 in cleaning the cleaning brush 200, but also allows the debris swept by the entangled brush 301 to fall directly into the dust box 304 through the entrance, improving the collection of debris. The hair cleaner 25 is positioned at the second end of the entangled brush 301, ensuring that all axial positions of the entangled brush 301 pass through the hair cleaner 25 during extraction, thereby enhancing the cleaning effect of the entangled brush 301.

[0156] To facilitate assembly and disassembly of the dust box 304, as shown in Figures 2 and 3, the floor brush housing 100 includes a floor brush base 106 and a floor brush cover 125. The top of the floor brush base 106 is provided with an opening, and the floor brush cover 125 is detachably connected to the floor brush base 106 to cover the opening. The floor brush base 106 is provided with a mounting slot that is compatible with the dust box 304. The dust box 304 is located in the mounting slot, making it easy to remove and place the dust box 304. The floor brush cover 125 is provided with a thumb groove and a release button 126 to facilitate assembly and disassembly of the floor brush cover 125.

[0157] To facilitate the removal or insertion of the hair-wrapping roller brush 301 from or into the mounting hole 232, the first end of the hair-wrapping roller brush 301 is detachably and rotatably connected to the inner wall of the dust box 304. The second end of the hair-wrapping roller brush 301 passes through the hair cleaner 25 and the mounting hole 232 and is detachably connected to the outer wall of the dust box 304. This arrangement allows one end of the hair-wrapping roller brush 301 to extend outside the dust box 304, making it easier for the user to grab and remove or install the hair-wrapping roller brush 301. At the same time, it ensures that the hair-wrapping roller brush 301 can rotate relative to the dust box 304, thereby ensuring that the cleaning roller brush 200 can perform its cleaning function.

[0158] In this embodiment, as shown in Figures 26, 27, and 28, the annular body 251 is connected to the dust box 304 and is sleeved outside the hair-entangled roller brush 301. The cleaning teeth 252 all extend obliquely toward the first end of the hair-entangled roller brush 301. The ends of the cleaning teeth 252 that come into contact with the hair are pointed 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.

[0159] The tooth portion 2521 of the cleaning tooth 252 helps to reduce the distance between the end of the cleaning tooth 252 and the surface of the hair roller brush 301, making it easier for the cleaning tooth 252 to extend into the hair bundle of the implanted hair and remove long foreign matter such as hair or thread from the hair bundle of the hair 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 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 roller brush 301, making it easier for the rib 2522 to be inserted between the hair and the hair roller brush 301, thereby improving the cleaning effect. Optionally, the extension direction of the rib 2522 can be roughly parallel to the axis of the hair roller brush 301, so that it can intercept long foreign matter such as hair or thread as the hair roller brush 301 is withdrawn.

[0160] 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.

[0161] Specifically, the annular body 251 includes a sleeve 2511, which is inserted into the mounting hole 232. The cleaning teeth 252 are connected to the inner wall of the sleeve 2511. The outer wall of the sleeve 2511 is connected to a first flange 2512, which is detachably connected to the dust box 304. The provision of the first flange 2512 increases the contact area between the annular body 251 and the dust box 304, 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 fasteners, wherein the fasteners are screws. In other embodiments, the first flange 2512 can be fixed by snapping with the dust box 304 to facilitate replacement of the hair remover 25.

[0162] To further enhance the securing of the hair cleaner 25 to the dust box 304, as shown in Figures 23 and 27, a second flange 2513 is connected to the outer wall of the sleeve 2511. The dust box 304 is provided with a socket 231, into which the second flange 2513 is inserted. The cooperation between the second flange 2513 and the socket 231 enables the hair cleaner 25 to be positioned with the dust box 304, facilitates the fastener connection between the first flange 2512 and the dust box 304, and enhances the securing effect.

[0163] 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.

[0164] To ensure that the brush roller 301 can rotate relative to the dust box 304 and facilitate its installation and removal, as shown in Figures 26-29, the floor brush 40 also includes a movable end cap 261. The movable end cap 261 is detachably mounted on the outer wall of the dust box 304 and covers the mounting hole 232. The second end of the brush roller 301 is rotatably connected to the movable end cap 261. When the user needs to remove the brush roller 301, the movable end cap 261 is removed to disengage the brush roller 301 from the dust box 304, allowing the brush roller 301 to be pulled out of the mounting hole 232. The movable end cap 261 also blocks the mounting hole 232 when the brush roller 301 is installed in the dust box 304, preventing debris from the dust box 304 from spilling out through the mounting hole 232, improving the user experience and ensuring aesthetics.

[0165] To facilitate assembly and disassembly of the movable end cover 261 and the dust box 304, a first suction member is provided on the outer wall of the dust box 304, and a second suction member is provided on the side of the movable end cover 261 facing the dust box 304. The first suction member and the second suction member are attracted to each other to secure the movable end cover 261 and the dust box 304. The attraction between the first and second suction members secures the movable end cover 261 and the dust box 304, making assembly and disassembly easy and having a simple structure.

[0166] To improve the relative positioning accuracy of the first and second suction components, a first positioning groove is provided on the outer wall of the dust box 304, into which the first suction component is fixed. A second positioning groove 2612 is provided on the side of the movable end cover 261 facing the dust box 304, into which the second suction component is fixed. The first positioning groove secures the first suction component, while the second positioning groove 2612 secures the second suction component, ensuring that the first and second suction components are aligned, thereby ensuring effective suction and fixation.

[0167] In some embodiments, the first positioning groove may be provided only on the dust box 304 , or the second positioning groove 2612 may be provided only on the movable end cover 261 , both of which can improve the fixing effect of the first adsorption member and the second adsorption member.

[0168] Furthermore, as shown in Figures 23 and 30 , the hair cleaner 25 also includes a third flange 2514. The third flange 2514 is located on the outside of the dust box 304. An annular flange 25141 is provided on the side of the third flange 2514 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 enhance the blocking effect of the third flange 2514 on the first positioning groove. The first and second adsorbents are located on either side of the third flange 2514. On the one hand, the third flange 2514 blocks the first positioning groove to protect the first adsorbent. On the other hand, the clamping action of the first and second adsorbents further secures the hair cleaner 25, ensuring the stability of the position of the hair cleaner 25.

[0169] To prevent the movable end cap 261 from rotating with the hair-entanglement roller brush 301, as shown in Figures 29 and 30 , a positioning notch 2611 is provided on the movable end cap 261, and a positioning protrusion 253 is provided on the hair cleaner 25. The positioning protrusion 253 is inserted into the positioning notch 2611. The cooperation between the positioning protrusion 253 and the positioning notch 2611 prevents the movable end cap 261 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 cap 261, and the positioning protrusion 253 is formed by extending the side wall of the sleeve 2511 away from the cleaning teeth 252, thereby simplifying the structure of the hair cleaner 25.

[0170] 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-wrapping roller brush 301 .

[0171] The floor brush 40 also includes a fixed end cap 262, which is fixedly mounted within the dust box 304. The first end of the bristle roller brush 301 is rotatably inserted into the fixed end cap 262. Specifically, the fixed end cap 262 is mounted on the side wall of the dust box 304 opposite the side wall where the mounting hole 232 is located. The fixed end cap 262 is provided with a first rotation hole, into which one end of the bristle roller brush 301 is inserted and rotatably engages. This arrangement is structurally simple and facilitates assembly and disassembly of the bristle roller brush 301 and the fixed end cap 262.

[0172] Specifically, as shown in Figure 31, the hair-wrapping 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 rotatably inserts into the first rotating hole of the fixed end cap 262. The second rotating shaft 243 is fixed to the other end of the rotating shaft 302 and rotatably connected to the movable end cap 261. The first and second rotating shafts 242, 243 can be fixedly connected to the rotating shaft 302 via a threaded pair. The end surface of the rotating shaft 302 is spaced apart from the inner wall of the dust collection box 304. The movable end cap 261 is provided with a second rotating hole, through which the second rotating shaft 243 passes. A clamp is mounted on the 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 cap 261 facing away from the dust collection box 304, thereby fixing the axial position of the second rotating shaft 243 and the movable end cap 261.

[0173] To better clean the hair on the entangled brush 301, the surface of the rotating shaft 302 of the entangled brush 301 is provided with at least two ridges 247. The ridges 247 extend axially along the rotating shaft 302, and the at least two ridges 247 are spaced apart along the circumference of the rotating shaft 302. The provision of at least two ridges 247 supports the hair wrapped around the entangled brush 301, preventing the hair from directly contacting the surface of the rotating shaft 302. This facilitates the cleaning teeth 252 to extend between the hair and the rotating shaft 302, thereby lifting the hair and improving the cleaning effect of the entangled brush 301.

[0174] 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 easier 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.

[0175] Optionally, the height of the ridges 247 is 0.3 mm to 1 mm, such as 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, or 0.9 mm. The clearance between the ends of the cleaning teeth 252 and the surface of the rotating shaft 302 other than the ridges 247 is 0.1 mm to 0.5 mm, such as 0.2 mm, 0.3 mm, or 0.4 mm. However, this clearance should be less than the height of the ridges 246, ensuring that the free ends of the cleaning teeth 252 can extend into the recessed areas formed between adjacent ridges 247 to facilitate the removal 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 teeth 252 and the surface of the hair rolling brush 301 when the hair rolling brush 301 is pulled out laterally to reduce the resistance encountered by the hair rolling brush 301 when it is pulled out.

[0176] In this embodiment, the bristle-wrapped roller brush 301 is a planted roller brush, i.e., bristles are planted on the rotating shaft 302. Specifically, the bristles 303 of the bristle-wrapped roller brush 301 include a first bristle assembly 244, which is disposed on the outer circumference of the rotating shaft 302. The first bristle assembly 244 includes multiple clusters of first bristles, which can contact the cleaning roller brush 200 to clean impurities such as hair and particulate matter thereon.

[0177] 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.

[0178] 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 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.

[0179] In this embodiment, there is one first bristle assembly 244. In other embodiments, there may be at least two first bristle assemblies 244, which are spaced apart along the circumference of the rotating shaft 302, forming multiple spirally arranged first bristles, so that hairs are more easily wrapped around the bristle wrapping roller brush 301, thereby improving the cleaning effect of the cleaning roller brush 200.

[0180] In this embodiment, the bristles 303 of the entangled roller brush 301 further include a second bristle assembly 245. The second bristle assembly 245 includes a plurality of tufts of second bristles that are spaced apart circumferentially along the rotating shaft 302. The second bristle assembly 245 is disposed at one end of the rotating shaft 302 that is adjacent to the hair cleaner 25. The provision of the second bristle assembly 245 can, on the one hand, appropriately increase the friction between the entangled roller brush 301 and the cleaning roller brush 200 as needed; on the other hand, it can prevent hair from contacting the second rotating shaft 243, thereby preventing the second rotating shaft 243 or the cleaning teeth 252 from becoming entangled in the hair, thereby preventing the second end of the entangled roller brush 301 and the movable end cap 261 from being inoperative or obstructed from rotating.

[0181] In addition, when the entangled roller brush 301 is pulled outward and the first end is about to be separated from the hair cleaner 25, a large amount of hair has accumulated on the second end of the entangled roller brush 301 and the end of the cleaning teeth 252, so the resistance between the 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 from struggling when pulling out the entangled roller brush 301, thereby improving the user experience.

[0182] In some embodiments, the entangled brush roller 301 may be provided with a second bristle assembly 245 at both ends to increase the friction between the entangled brush roller 301 and the cleaning brush roller 200 according to actual needs.

[0183] To prevent hair from moving toward the first end of the entangled roller brush 301 and entering the first rotating hole, the bristles 303 of the entangled roller brush 301 also include a third bristle assembly 246. The third bristle assembly 246 is disposed at the first end of the roller brush and includes multiple tufts of third bristles. The tops of the third bristles extend obliquely toward the side wall of the dust box 304 connected to the first end of the entangled roller brush 301. In other words, the third bristles extend obliquely upward from the surface of the rotating shaft 302 and toward the fixed end cap 262 to prevent hair from entering the first rotating hole, thereby ensuring the rotational coordination between the first rotating shaft 242 and the first rotating hole.

[0184] In some possible implementations, the 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 entangled roller brush 301 to ensure that the entangled roller brush 301 passes through the hair cleaner 25 at all axial positions during the extraction process, so as to improve the cleaning of the surface of the entangled roller brush 301.

[0185] In order to achieve a better cleaning effect, this 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 likely to cause the ridge 247 to break. To avoid the ridge 247 from breaking, 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 ridge 247 from breaking. 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, which makes it difficult for the user to operate when disassembling the bristle roller 301. Disassembly and assembly are difficult, but the cleaning effect of linear bristle implantation is poor.

[0186] To address the above-mentioned issues, the outer circumferential surface of the rotating shaft 302 includes an inner concave arc surface and an outer convex arc surface that are alternately arranged along the circumference, with a ridge 247 formed on the outer convex arc surface. By alternating 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, with the curvature of the curve 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. This structure of the rotating shaft 302 can not only form the ridge 247, but also enable the ridge 247 to have a relatively gentle height, so that even if bristles are implanted on the ridge 247, the ridge 247 will not break. In this way, the location and method of the bristle implantation are not restricted, and there is no need to avoid the ridge, and the distribution of the bristle implantation on the circumferential surface is more uniform. The smaller height of the ridge 247 can also reduce the resistance encountered when the hair-wrapped roller brush 301 is withdrawn, making the disassembly and assembly of the hair-wrapped roller brush 301 more labor-saving and improving the user experience.

[0187] 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 one 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.

[0188] Of course, in some other possible implementations, the floor brush 40 may not be provided with a entangled brush 301, and may only include at least one cleaning brush 200 to clean the surface to be cleaned (such as the ground); or the cleaning brush 200 may not be provided, and may only include at least one entangled brush 301 to clean other surfaces to be cleaned inside the floor brush 40. These settings can be made according to actual needs.

[0189] Regardless of the number combination of the cleaning roller brush 200 and the hair-entangled roller brush 301, a corresponding hair cleaner 25 can be set according to actual needs and structure to ensure that the cleaning roller brush 200 and / or the hair-entangled roller brush 301 pass through the cleaning teeth 252 of the hair cleaner 25 at all axial positions during the extraction process, so as to improve the cleaning of the surface of the cleaning roller brush 200 and / or the hair-entangled roller brush 301.
