FIG. 6 is a schematic view of an embodiment of a cutting element wrapped by a protective element. FIG. 7 is an elevation view of a cutting element according to one embodiment. FIG. 8 is a perspective view of a cutting element according to one embodiment. FIG. 9 is a perspective view of a cutting blade in one embodiment. FIG. 10 is a side view of a cutting element according to one embodiment. The direction of the arrow in fig. 5 is the cutting direction, i.e., the opening direction of the slit. The cutting device 92 for the roller brush 21 shown in the drawing includes a cutting member 921 and a driving mechanism 926, and the cutting member 921 is used for cutting sundries wound on the surface of the roller brush 21. The drive mechanism 926 is configured to drive the cutter 921 in the direction of extension of the axis. In this embodiment, the driving mechanism 926 includes a cutting motor and a transmission mechanism, which may be a screw transmission, a belt transmission, a hydraulic transmission, etc., and the above-mentioned transmission mechanism is merely exemplary and not limiting, and other transmission mechanisms known to those skilled in the art that are not listed may also be applied to the present invention. The driving mechanism 926 is configured to drive the cutting member 921 to move in the axial direction of the roller brush 21 after the cleaning head 2 is docked to the base body 91 to cut the sundries wrapped around the roller brush 21.

In the embodiment shown in fig. 3, the transmission mechanism is a screw transmission structure, the screw is substantially parallel to the rolling brush 21, one end of the screw is in transmission connection with the cutting motor, the cutting member 921 is sleeved on the screw through a thread, when the output shaft of the cutting motor rotates, the screw is driven to rotate, the screw drives the cutting member 921 to move along the axial direction of the screw through the thread, so as to cut off the sundries wound on the rolling brush 21, and the cut-off sundries are collected in the dirt collection chamber when the rolling brush 21 rotates again.

With continued reference to fig. 7-10, wherein the cutting member 921 includes at least one cut 925, the cut 925 is defined by the alternating edges 94 of the two cutting blades 922, the cut 925 opening in the direction of axial extension, the cutting direction of the cutting member 921, the distance between the two edges 94 increasing. The cutting element may also comprise a plurality of notches arranged side by side in a zigzag pattern, but with a plurality of notches, the shape of the notches may be somewhat smaller. The cutting blade 922 may be a metal material, or may be other materials such as a ceramic material that can be used to form the sharpened edge 94. In one embodiment, the two cutting blades 922 may be integrally formed (see fig. 7 and 8), for example, after a cut 925 is made in a mold, a cutting edge 94 is then machined at the cut 925, and so on. In another embodiment, two separate blades (see fig. 9 and 10) may be connected together by welding or gluing. The cutting edges 94 of the two cutting blades 922 are single-edged and the two single edges face away from each other at least in the area of intersection (the dashed circular area shown in fig. 8 is illustrated as the area of intersection, where the circle is merely illustrative and the area size is not particularly limited). Specifically, the cutting edge 94 of one blade faces one side, the cutting edge 94 of the other blade faces the other side, the two cutting edges 94 are oppositely arranged and close to each other, and because the two cutting edges 94 meet at one point, with this arrangement, hairs wound on the roller brush 21 are cut off in the process of moving to the meeting point, and after hairs which are not cut off in the meeting area move to the meeting point, because the meeting point can be regarded as a point theoretically, hairs at this point can be cut off by one of the two cutting edges 94, and hairs cannot be effectively cut off due to the fact that there are unfavorable conditions such as roundness and the like at the meeting point. (when the blade 94 at the cut 925 is double-edged, an arc-shaped intersection structure is easily formed at the intersection point due to the limitation of the processing technology, and the hair is not easily cut after moving to the intersection point).

In a further embodiment, the angle of the cutout 925 is less than 90 degrees in order to enhance the cutting effect.

In a specific embodiment, to further improve the cutting effect and reduce the cost, the two cutting blades 922 are single-edge blades, each of which includes a cutting edge face 941 and an abutting face 942 opposite to the cutting edge face 941, the two abutting faces 942 are substantially planar and the two abutting faces 942 partially fit into each other to form the cutout 925. When the blades are made of metal materials, the abutting surfaces 942 of the two blades can be contacted, at this time, the cutting edges 94 of the two blades can be effectively ensured to be infinitely close to each other, and then the two blades are fixed together through gluing or welding, and gaps can be effectively prevented from being generated between the two cutting edges 94 (in the overlapping direction).

Referring to fig. 6, further, in order to provide effective protection to the roll brush 21 or a user, the cutting member 921 is provided at its outer circumference with a protection member 95, and the protection member 95 is configured to expose at least the blade edge 94 located at the intersection area. That is, only the blade 94 of the intersection region is exposed to perform the cutting function, while the other regions are partially or completely covered by the protective member 95, the protective member 95 may be a plastic housing, detachably or non-detachably attached to the outer periphery of the cutting member 921, and the protective member 95 may be hardened by an encapsulating process except for the intersection region. With continued reference to fig. 6, at least a portion of the guard 95 adjacent the periphery of the cutting blade 922 of the roller brush 21 is tapered and gradually reduces in cross-sectional area in the cutting direction. Since the portion of the protector 95 is in contact with the roller brush 21 and is tapered, it is possible to protect the roller brush 21 and guide the hairs to the meeting area.

Referring to fig. 6, in other embodiments, a protection member 95 may be separately provided near the outer circumference of the cutting blade 922 of the roll brush 21, and at least a portion of the protection member 95 is tapered and gradually reduces in cross-sectional area in the cutting direction.

Referring to fig. 5, the driving mechanism 926 includes a mounting member 96, and the cutting member 921 is drivingly connected to the driving mechanism 926 through the mounting member 96. The cutter 921 is mounted to the mount 96 by a protector 95. Cost and installation space can be effectively saved.

The utility model also provides a cutting device 92 for a roller brush 21, the roller brush 21 being rotatable about its own axis during operation, the cutting device 92 comprising a cutting member 921 and a drive mechanism 926. The cutting member 921 is used to cut the sundries wound on the surface of the drum brush 21. The drive mechanism 926 is configured to drive the cutting device 92 in the direction of extension of the axis. Wherein the cutting member 921 includes at least one cut 925, the cut 925 being defined by the alternating edges 94 of the two cutting blades 922, the edges 94 of the two cutting blades 922 meeting at a point of intersection. The cutting edges 94 of the two cutting blades 922 may be all single-edged, one may be single-edged and the other may be double-edged, or both may be double-edged, it being understood that it is only necessary to ensure that the cutting edges 94 of the two blades are in contact to ensure that the intersection of the two cutting edges 94 approaches an infinite point, rather than a point of intersection that is rounded or not sharp, etc. The material and mounting method of the cutting blade 922 will not be described in detail, and reference may be made to the above-described embodiments.

To save cost and ease of installation, cutting blade 922 includes a cutting edge face 941 and an abutment face 942 opposite cutting edge face 941, the two abutment faces 942 being substantially planar and the two abutment faces 942 partially conforming to one another to form cutout 925.

In one embodiment, the roller brush 21 includes first and second ends disposed opposite to each other in the axial direction, and the cutting member 921 is movable from the first end to the second end of the roller brush 21. The cutting piece 921 is moved from one end of the roll brush 21 to the other end, and the whole roll brush 21 can be effectively cleaned, and the entanglement is prevented from remaining on the roll brush 21. Further, the cutting piece 921 is formed in the same direction over the length of the roll brush 21, so that the outermost edge of the roll brush 21 can be cut off. The cutting member 921 is the cutting member 921 in any of the above embodiments.

In a further embodiment, the cutting member 921 makes at least one reciprocating movement in the axial direction of the roll brush 21 in one working cycle. The cutting member 921 performs one reciprocating motion to further ensure the cutting of the wound object. The cutting member 921 has a start position and/or a final position during a working cycle of the cutting member 921, and the cutting member 921 is hidden in the base body 91 when the cutting member 921 is located at the start position and/or the final position. Set up like this, can hide effectively when cutting piece 921 is inoperative, avoid the user to cause the injury after the mistake. Further, when meeting the condition that cutting piece 921 can not cut off, cutting piece 921 meets and hinders promptly, and the motor takes place the locked rotor, and at this moment, motor control cutting piece 921 back movement one end distance after, cuts again, perhaps directly resets, sends signal for the controller, and the controller sends alarm signal.

The present invention also discloses a cleaning system comprising a surface cleaning apparatus 100 and a base 9 of any of the above embodiments of docking cleaning systems, the base 9 typically being connected by electrical wiring to a municipal power source for providing power to the drive mechanism 926, although it will be appreciated that the drive mechanism 926 on the base 9 may also be powered by a battery of the cleaning apparatus. Surface cleaning apparatus 100 includes a controller configured to control drive mechanism 926 to drive cutting member 921 after surface cleaning apparatus 100 is docked to base 9.
