When the dust box 304 is installed in the accommodating space 107, the opening 305 on the dust box 304 is engaged with the communication port 109, and the brush 301 rotates to sweep the solid garbage on the cleaning brush 200 into the dust box 304. Wherein, the lower edge 307 of the opening 305 of the dust collecting box 304 extends into the communication port 109 or directly abuts against the communication port 109 to be connected with the communication port 109. In the structure shown in fig. 9, the lower edge 307 of the opening 305 of the dust box 304 extends into the communication port 109 and contacts the cleaning roller brush 200, and the solid garbage cleaned by the brush 301 from the cleaning roller brush 200 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 an upper portion of the dust box 304, and the haired rolling brush 301 is positioned at a rear upper portion of the cleaning rolling brush 200. An opening 305 is provided at the upper portion of the dust box 304, and solid garbage swept down from the cleaning roller brush 200 can be deposited 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 not less than 1/3 of the diameter of the cleaning cylinder 201.

In one possible implementation, the opening 305 is provided in an upper portion of the dust box 304 and extends from a side of the dust box 304 adjacent to the cleaning roller brush 200 to a top surface of the dust box 304, and the brush roller 301 is adjacent to a lower edge 307 of the opening 305. This design provides a larger opening 305 in the dust bin 304 to facilitate receiving solid debris stripped from the cleaning brush 200 by the brush 301 and to facilitate cleaning of the dust bin 304 by a user. In addition, since the opening 305 extends to the top of the dust box 304, an additional cover plate is required to be provided for shielding, and in the structure shown in fig. 2 and 3, the cover plate covers the top of the dust box 304 through the floor brush 40, so that solid garbage in the dust box 304 is prevented from being spilled, and meanwhile, the overall and attractive appearance can be maintained.

In another possible implementation, the opening 305 is provided at a side of the dust box 304 near the cleaning roller brush 200 and at an upper portion of the dust box 304, and a top of the dust box 304 is closed. This design eliminates the need for an additional cover plate to cover the dust box 304, and in the configuration shown in fig. 13 and 14, the top of the dust box 304 is further provided with a handle 306, and when the brush cover 125 is covered on the brush base 106, the top of the dust box 304 is exposed from the brush cover 125, so that a user can quickly take out and replace the dust box 304 by operating the handle 306.

When the cleaning roller brush 200 drives the hair winding roller brush 301 to rotate, the rotation direction of the hair winding roller brush 301 is opposite to the rotation direction of the cleaning roller brush 200. In one possible implementation, the brush roller 301 always rotates from a position in interference fit with the brush roller 200 toward the top of the dust box 304, and accordingly, the brush roller 200 rotates from a position in interference fit with the brush roller 301 toward the top of the brush housing 100, and solid waste that the brush roller 301 sweeps off the brush roller 200 can directly enter the bottom of the dust box 304, while hair is entangled on the brush roller 301, thereby reducing or preventing hair from being entangled on the brush roller 200.

The brush 301 includes a rotating shaft 302 and bristles 303 provided on an outer surface of the rotating shaft 302. The brush 301 may be provided on the floor brush housing 100 or on the dust box 304. Since both the brush 301 and the dust box 304 need to be cleaned, both the brush 301 and the box 304 need to be detachable. In the configuration shown in fig. 5 and 15, the brush 301 is provided to the dust box 304, and the user can take out the brush 301 together when taking out the dust box 304. In one possible implementation manner, since the dust collecting box 304 is provided with the opening 305 which is large enough, the winding brush 301 does not block the opening 305, so that the winding brush 301 is not required to be detached from the dust collecting box 304 during cleaning, the convenience of use can be improved, and the user experience can be improved.

The cleaning rolling brush 200 comprises a cleaning cylinder 201 and a power device 202, wherein the power device 202 drives the cleaning cylinder 201 to rotate.

In this embodiment, as shown in fig. 20, the hair remover 25 further includes a ring-shaped body 251, the ring-shaped body 251 is connected with the floor brush housing 100 or the dust box 304, and the ring-shaped body 251 can be sleeved outside the cleaning roller. One end of the cleaning teeth 252 is connected to the inner side surface of the ring body 251, and the other end of the cleaning teeth 252 extends obliquely toward one end of the cleaning roller away from the mounting hole. The cleaning teeth 252 are obliquely arranged, so that the end parts of the cleaning teeth 252 can pick up long-strip-shaped foreign matters such as hairs or lines on the cleaning roller more easily when being pulled out, the long-strip-shaped foreign matters such as hairs or lines are ensured to be wound on the cleaning teeth 252, and the cleaning effect on the cleaning roller is improved.

To further facilitate the picking up of long and long, hair-like or string-like foreign matter by the cleaning teeth 252, as shown in fig. 20 and 21, the cross-sectional area of the cleaning teeth 252 is gradually reduced in a direction away from the ring-shaped main body 251, so that the end of the cleaning teeth 252 contacting the hair is a tip with a smaller cross-section, which facilitates the insertion of the cleaning teeth 252 between the cleaning roller and the long, hair-like or string-like foreign matter, thereby preventing the long, hair-like or string-like foreign matter from being pulled out of the floor brush housing 100 or dust box 304 with the cleaning roller. Wherein the cross section of the cleaning teeth 252 is perpendicular to the length direction of the cleaning teeth 252. As shown in fig. 21, a line defining the center of the tooth root to the center of the tooth tip of the cleaning tooth 252, which intersects the axis b of the ring body 251, is the length of the cleaning tooth 252. The length direction of the cleaning teeth 252 is the X direction, the section a is perpendicular to the X direction, and the section obtained by cutting the cleaning teeth 252 by the section a is a cross section. Here, the length direction of each cleaning tooth 252 is different, and the X direction in fig. 21 is the length direction corresponding to the cut cleaning tooth 252.

In this embodiment, the longitudinal section of the cleaning teeth 252 is trapezoidal, one bottom of the trapezoid is connected to the annular main body 251, the other bottom of the trapezoid forms an end face of the free end of the cleaning teeth 252, and both sides of the trapezoid are inclined toward one end of the cleaning roller far away from the mounting hole. The longitudinal section is a section parallel to the longitudinal direction of the cleaning teeth 252 and passing through the axis b of the ring body 251. The longitudinal section is the section of the cleaning teeth 252 shown in fig. 21.

Specifically, cleaning teeth 252 include teeth 2521, where teeth 2521 include a first flank, a second flank, a third flank, a fourth flank, and a top land. Wherein the first and second flanks are aligned in the axial direction of the ring body 251, and the third and fourth flanks are aligned in the circumferential direction of the ring body 251. One end of the first flank, the second flank, the third flank and the fourth flank are all connected with the annular main body 251, and the other end is all connected with the tooth top surface, so that the cleaning teeth 252 are approximately of a quadrangular prism structure, and the tooth top surface forms the free end of the tooth portion 2521. To make the end of the cleaning teeth 252 smaller in size, the first and second flanks each extend obliquely toward the end of the cleaning roller remote from the mounting hole, and the distance between the third and fourth flanks gradually decreases in the radial direction of the mounting hole toward the center of the mounting hole.

In other embodiments, the cleaning teeth 252 may have other shapes, such as a circular, oval, or irregular shape in cross-section of the cleaning teeth 252.

To better catch on the long and thin foreign objects such as hair or wire, in one possible implementation, the cleaning teeth 252 include teeth 2521 and ribs 2522 disposed at an included angle, one end of the teeth 2521 is connected to the ring body 251, the other end is connected to the ribs 2522, and the teeth 2521 extend from the inner side of the ring body 251 toward the center of the mounting hole and are inclined toward the end of the cleaning roller away from the mounting hole. The ribs 2522 extend from the teeth toward an end of the cleaning roller remote from the mounting aperture. By arranging the tooth parts 2521, the distance between the end part of the cleaning teeth 252 and the surface of the cleaning roller is reduced, so that the cleaning teeth 252 can conveniently extend into the hair or the linear long-shaped foreign matters to be contacted with the hair or the linear long-shaped foreign matters, the included angle between one side of the convex rib 2522, which faces the center of the mounting hole, and the surface of the cleaning roller is smaller than the included angle between one side of the tooth part 2521, which faces the center of the mounting hole, and the surface of the cleaning roller, and the convex rib 2522 is easier to be inserted between the hair or the linear long-shaped foreign matters and the cleaning roller, so that the cleaning effect is improved.

Alternatively, as shown in fig. 22, the extending direction of the ribs 2522 may be substantially parallel to the axis of the cleaning roller so as to be able to intercept a long-shaped foreign matter such as hair or wire as the cleaning roller is pulled out.

In this embodiment, the diameter of the circular area surrounded by the free ends of the 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 improving the cleaning effect on the foreign matters. The interference of the cleaning teeth 252 with the cleaning roller should be set relatively small for the above-mentioned sponge rolling brush, soft velvet rolling brush or lint rolling brush to avoid increasing the withdrawal resistance of the cleaning roller, the interference of the cleaning teeth 252 with the cleaning roller should be set relatively large for the above-mentioned soft rubber rolling brush, flocked rolling brush to facilitate improving the cleaning effect on long and long foreign matters such as wound hair or wire on the bristles, and the soft rubber or bristle bundles have a certain flexibility and can be deformed to pass through the circular area.

In one possible embodiment, the area of the cleaning teeth 252 in contact with the cleaning roller has at least one edge that can apply a shearing force to the wound hair or wire-like long-strip-like foreign matter when the cleaning teeth 252 pick up the foreign matter so that the hair or wire-like long-strip-like foreign matter can be severed to enhance the cleaning effect of the foreign matter.

In this embodiment, the cleaning roller includes at least two cleaning roller brushes 200 and at least one brush roller brush 301, in which the cleaning roller brush 200 is selected as a sponge roller brush, the brush roller brush 301 is selected as a brush roller brush, and other suitable types of brush roller may be selected according to actual requirements. The cleaning roller brush 200 is rotatably arranged on the bottom surface of the ground brush housing 100 and is used for contacting with a surface to be cleaned (such as the ground) to clean dirt, the dust collecting box 304 is detachably arranged in the ground brush housing 100, an inlet is arranged on one side of the dust collecting box 304 facing the cleaning roller brush 200, and the hair winding roller brush 301 is rotatably arranged at the inlet of the dust collecting box 304 and can be abutted with the cleaning roller brush 200 to clean the dirt on the surface to be cleaned (such as the cleaning roller brush 200).

In the following description, taking an example that the cleaning roller includes one cleaning roller brush 200 and one brush roller 301, the axes of the brush roller 301 and the cleaning roller brush 200 are parallel, and the axial dimensions of the brush roller 301 and the cleaning roller brush 200 may be approximately equal to improve the cleaning effect of the brush roller 301 on the cleaning roller brush 200. As shown in fig. 23, mounting holes 232 and hair cleaners 25 are provided at positions corresponding to the hair-winding roller brushes 301, and the circumferential outer walls of the hair-winding roller brushes 301 are brought into contact with the cleaning teeth 252 on the hair cleaners 25 during the extraction of the hair-winding roller brushes 301 through the mounting holes 232 to clean the hair-winding roller brushes 301.

The axes of the brush 301 are parallel to the axis of the brush 200, and are all disposed along the longitudinal direction of the brush 40. When the floor brush 40 moves on a surface to be cleaned (e.g., the floor), the cleaning roller brush 200 actively rotates clockwise as viewed in fig. 9, and the trash such as hair, debris, etc. on the surface to be cleaned can adhere to the cleaning roller brush 200 and move with the cleaning roller brush 200. Since the brush 301 abuts against the cleaning roller brush 200, the brush 301 can be driven to rotate by the cleaning roller brush 200, that is, the brush 301 is not provided with a driving device and is driven to rotate counterclockwise by the cleaning roller brush 200. It should be noted that, the cleaning roller brush 200 is in interference fit with the brush 301, and the brush 301 is driven by the cleaning roller brush 200 to rotate, but the contact point of the cleaning roller brush 200 and the brush 301 moves relatively, and the rotation speeds of the two are different, so that the brush 301 can clean dirt on the brush 200. The brush 301 cleans the surface of the cleaning roller brush 200, so that the impurities such as hairs and chips adhered to the surface of the cleaning roller brush 200 can be peeled off from the cleaning roller brush 200 and enter the dust collecting box 304 through the inlet of the dust collecting box 304, thereby realizing garbage collection. Of course, the number of the cleaning roller brush 200 or the brush roller 301 may be plural, one brush roller 301 may be disposed corresponding to one cleaning roller brush 200, one brush roller 301 may be disposed corresponding to plural cleaning roller brushes 200, or plural brush roller brushes 301 may be disposed corresponding to one cleaning roller brush 200, or plural brush roller brushes 301 may be disposed corresponding to plural cleaning roller brushes 200, all of which may be disposed according to actual requirements.

In order to better clean the hair on the hair-winding roller brush 301, the surface of the rotation shaft 302 in the hair-winding roller brush 301 is provided with at least two ribs 247, the ribs 247 extend in the axial direction of the rotation shaft 302, and the at least two ribs 247 are arranged at intervals in the circumferential direction of the rotation shaft 302. By arranging at least two ribs 247, the hair wound on the hair winding roller brush 301 is supported by the ribs 247, and the hair is prevented from directly contacting the surface of the rotating shaft 302, so that the cleaning teeth 252 can conveniently extend between the hair and the rotating shaft 302, the hair is lifted, and the cleaning effect on the hair winding roller brush 301 is improved.

Further, the end of the cleaning teeth 252 is lower than the top surface of the ribs 247, and at the same time, a gap exists between the end of the cleaning teeth 252 and the surface of the rotating shaft 302 outside the ribs 247, so that the cleaning teeth 252 can conveniently extend between the hair and the rotating shaft 302 and friction between the cleaning teeth 252 and the surface of the rotating shaft 302 is reduced.

Alternatively, the height of the ribs 247 is 0.3mm to 1mm, such as 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, or 0.9mm. The clearance between the end of the cleaning teeth 252 and the surface of the rotating shaft 302 other than the ribs 247 is 0.1mm to 0.5mm, for example, 0.2mm, 0.3mm, and 0.4mm. But ensures that the gap is less than the height of the ribs 246, i.e., that the free end of the cleaning teeth 252 can extend into the recessed areas formed between adjacent ribs 247 to facilitate lifting of the entangled hair. The ribs 247 and gaps in the height ranges described above not only ensure that the hair is effectively supported and prevent direct contact between the hair and the rotating shaft 302 to facilitate the end of the cleaning teeth 252 extending between the hair and the surface of the rotating shaft 302, but also allow for possible contact between the cleaning teeth 252 and the surface of the brush 301 when the brush 301 is drawn sideways to reduce the drag experienced by the brush 301 when drawn.

In this embodiment, the winding brush 301 is a brush roller, i.e. the brush roller 302 is implanted with bristles. Specifically, the bristles 303 of the wound brush roller 301 include a first bristle assembly 244, the first bristle assembly 244 being disposed on the outer circumferential surface of the rotating shaft 302, the first bristle assembly 244 including a plurality of tufts of first bristles, the first bristles being capable of contacting the cleaning brush roller 200 to thereby clean hair and foreign substances such as particles thereon.

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

Further, the distribution mode that the first bristles of the multiple clusters are arranged in an S-shaped manner or in a spiral manner enables the first bristle component 244 to form multiple point contacts with the cleaning roller brush 200, compared with the line contact between the bristles of the multiple clusters and the cleaning roller brush when the bristles are arranged in a straight line, the friction force between the winding roller brush 301 and the cleaning roller brush 200 can be reduced, and the winding roller brush 301 is ensured to clean sundries on the cleaning roller brush 200 with reasonable contact force and contact points.

In this embodiment, the number of first bristle sub-assemblies 244 is one. In other embodiments, the number of the first bristle assemblies 244 may be at least two, and at least two first bristle assemblies 244 are spaced along the circumference of the rotating shaft 302, i.e. form multiple first bristles in a spiral arrangement, so that the hair is more easily wound on the brush roller 301, thereby improving the cleaning effect of the cleaning roller brush 200.

In this embodiment, the bristles 303 of the wound brush roller 301 further include a second bristle assembly 245, the second bristle assembly 245 includes a plurality of clusters of second bristles, the plurality of clusters of second bristles are disposed at intervals along the circumferential direction of the rotating shaft 302, and the second bristle assembly 245 is disposed at one end of the rotating shaft 302 near the hair remover 25. By arranging the second bristle assembly 245, on one hand, the friction force between the hair winding roller brush 301 and the cleaning roller brush 200 can be properly increased according to actual needs, and on the other hand, hair can be prevented from contacting the second rotating shaft 243, so that the problem that the second end of the hair winding roller brush 301 and the movable end cover 261 are invalid or blocked due to hair winding or the cleaning teeth 252 is avoided.

In addition, when the hair winding roller brush 301 is pulled out and the first end is separated from the hair remover 25, more hair is accumulated on the second end of the hair winding roller brush 301 and the end of the cleaning teeth 252, so that the resistance between the hair winding roller brush 301 and the hair remover 25 is large, and therefore, the second bristle assembly 245 is not arranged at the end, far away from the hair remover 25, of the rotating shaft 302, so that the user can be prevented from wasting effort when pulling out the hair winding roller brush 301, and the user experience is improved.

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

To prevent hair from moving toward the first end of the brush 301 and into the first rotation hole, the bristles 303 of the brush 301 further include a third bristle assembly 246, the third bristle assembly 246 being disposed at the first end of the brush, the third bristle assembly 246 including a plurality of tufts of third bristles, the tops of the third bristles extending obliquely toward the side wall of the dust box 304 to which the first end of the brush 301 is attached. I.e., 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 securing the rotating fit of the first rotating shaft 242 with the first rotating hole.

In some possible implementations, the brush roller 301 may be disposed on the brush housing 100 outside the dust box 304, and accordingly, the hair remover 25 and the movable end cap 261 are disposed following the brush roller 301 to ensure that the brush roller 301 passes through the hair remover 25 at every position in the axial direction thereof during the drawing process, so as to improve cleaning of the surface of the brush roller 301.

For better cleaning effect, the first bristles are arranged spirally around the axis of the rotating shaft 302, however, the bristles may be implanted on the rib 247, and the height of the rib 247 is steep, that is, the curvature change at the junction of the rib 247 and the non-rib is large, so that the rib 247 is easy to break. To avoid the breakage of the rib 247, a notch is usually provided on the rib 247 to avoid the bristle implantation position, or no bristle implantation is performed on the rib 247 to avoid the breakage of the rib 247. In addition, the height of the rib 247 may cause a large resistance of the hair cleaner to the brush 301 when the brush 301 is pulled out, and the user may have difficulty in assembling and disassembling the brush 301, but may have poor cleaning effect of the linear hair-planting.

To solve the above-described problem, the outer peripheral surface of the rotating shaft 302 includes concave and convex cambered surfaces alternately arranged in the circumferential direction, and ribs 247 are formed at the convex cambered surfaces. The cross-sectional profile of the rotating shaft 302 can be made to be a curve with different curvatures by alternately arranging the concave cambered surface and the convex cambered surface, and the curvatures of the curve are alternately arranged positive and negative, 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 concave and convex cambered surfaces may or may not be equal. The structure of the rotating shaft 302 can form the convex rib 247, and the convex rib 247 can be gradually high, so that even if bristles are implanted into the convex rib 247, the convex rib 247 cannot be broken, the bristle implantation position and mode are not limited, the convex rib does not need to be avoided, and the bristle implantation distribution on the circumferential surface is more uniform. The small height of the convex rib 247 can also reduce the resistance applied when the hair winding rolling brush 301 is pulled out, so that the hair winding rolling brush 301 is more labor-saving to assemble and disassemble, and the use experience of a user is improved.

It will be appreciated that in the above embodiments, the floor brush 40 comprising one cleaning roller brush 200 and one brush roller 301 is one possible implementation, and in some other possible implementations, the floor brush 40 may comprise at least one cleaning roller brush 200 and at least one brush roller 301, and the number of cleaning roller brushes 200 and brush roller 301 may be selected and combined according to actual requirements to improve the cleaning effect.

Of course, in some other possible implementations, the floor brush 40 may not be provided with the brush roller 301, and only include at least one cleaning roller brush 200 to clean a surface to be cleaned (such as a floor), or may not be provided with the cleaning roller brush 200, and only include at least one brush roller 301 to clean other surfaces to be cleaned inside the floor brush 40, which may be set according to practical requirements.

Regardless of how the cleaning roller brush 200 and the hair-winding roller brush 301 are combined in number, the corresponding hair cleaners 25 can be arranged according to actual requirements and structures so as to ensure that all positions of the cleaning roller brush 200 and/or the hair-winding roller brush 301 in the axial direction pass through the cleaning teeth 252 of the hair cleaners 25 during the extraction process, so that the surface of the cleaning roller brush 200 and/or the hair-winding roller brush 301 is cleaned.
