Detailed Description
The invention will be better explained by the following detailed description of the embodiments with reference to the drawings. Wherein references herein to azimuthal nouns such as "upper", "lower", "left" and "right" are made to the orientation of fig. 1. The end of the drum 10 connected to the movable end housing 13 through the first roll brush end cap is defined as "left".
In one aspect, a bristle cutting roller brush, as shown in fig. 1, 2, and 8, includes a roller 10, bristles 20 disposed on the roller 10, and a roller brush fixing end housing 13. Wherein, the circumferential side wall of the roller 10 is formed by splicing two semicircular sector shells 11. First and second brush end caps (not shown) and 12 are provided at left and right ends of a circumferential side wall of the drum 10, respectively, and the first and second brush end caps 12 are disposed in parallel with each other to form the drum 10 having an inner cavity. The two fan-shaped shells 11 can be wedged by using a fastener such as a screw, or can be bonded by using ultrasonic waves or glue.
Referring to fig. 9 and 10, the roll brush fixing end housing 13 includes a connection housing 131 provided at one end of the drum 10 and fixed to the drum 10. The right end of the first rolling brush end cover is fixed with the left end of the roller 10, and the left end of the first rolling brush end cover is buckled with the connecting shell 131. The left end of the second roll brush end cover 12 is fixed to the right end of the drum 10. The right end of the second roll brush end cover 12 is fixedly connected with a cleaner fixing end housing 313 detachably connected with the cleaner body 30. The end of the drum 10 connected to the cleaner body 30 is detachably connected for cleaning. However, the gap between the drum 10 and the connection case 131 is too large, so that foreign materials enter the gap to affect the dust collection effect of the cleaner. Therefore, the bristles 20 are extended in an axial length of the coupling case 131 to interfere with each other for blocking foreign matters from entering the gap, thereby avoiding a phenomenon that the entering of the winding at the gap rotation shaft at the left end of the drum 10 is difficult to clean. The winding is more advantageously cut off, and the axial length of the coupling housing 131 is extended to collide with the bristles 20 so that the winding is not easily entered into the gap, preventing the drum from being entangled into the winding during cleaning.
Further, the connection housing 131 has a ring structure having an outer ring and an inner ring, and the inner ring forms a through hole sleeved at the left end of the outer sidewall of the drum 10. An annular sealing ring 15 is arranged at one end of the outer ring, which is close to the roller 10. The left end of the drum 10 is an interference fit with the outer ring, as seen in fig. 10.
Further, the outer ring protrudes annularly with respect to one end of the drum 10.
Further, the outer ring partially protrudes with respect to one end of the drum 10.
Further, the width of the annular seal ring along the circumferential direction thereof was 2.5mm. Preferably, the outer circumferential surface of the connection housing 131 is inclined so as to guide the winding wound around the surface thereof onto the blade of the first bristle section 40.
The roller brush fixing end housing 13 further includes an end housing wall 132 disposed at the left side of the connection housing 131, and the bottom end of the end housing wall 132 is detachably connected with the cleaner main body 30, the top end of the end housing wall 132 penetrates through the inner ring of the connection housing 131 to be connected with the roller 10, and the rotating shaft of the roller 10 can relatively rotate on the end housing wall 132. The top of the end cap wall near one side of the drum 10 is formed with symmetrically disposed ribs extending along the bristle axis.
Specifically, a fitting 14 having dimensions of 7.4mm×2.9mm×2.5mm in length, width and height is also included. The purpose is to facilitate the assembly of the connection housing 131. Fitting 14 includes protruding arcuate first and second portions with the first portion being connected to a stiffener. The second portion protrudes from the outer ring, as shown in fig. 10.
The left end of the second rolling brush end cover 12 is fixed with the right end of the roller 10, and the end face of the right end of the second rolling brush end cover 12 is fixedly connected with a roller rotating assembly.
The drum 10 is provided with a first cut-out 40 and a second cut Mao Duan. The first cutout segment 40 and the central axis of the drum 10 lie in a first plane. The second cut Mao Duan and the central axis of the drum 10 are located at a second plane, and an included angle between the second plane and the first plane ranges from 90 ° to 180 °. The length of the first and second cuts Mao Duan, 40 is less than the length of the drum 10, and the length of the first and second cuts Mao Duan, 40 is greater than or equal to 1/3 of the length of the drum 10.
A centrifugal driving member is provided in the inner cavity of the drum 10, and pushes the first and second hair-cutting sections 40 and Mao Duan 50 to move left and right in the axial direction of the drum 10 by centrifugal force. So that the winding around the drum 10 is cut off.
Further, the internal cavity is also provided with a limiting block for limiting the transverse movement distance of the first hair segment 40 and the second hair segment Mao Duan; in addition, the internal cavity is also provided with an elastic restoring member that restores the first and second hair segments 40 and Mao Duan 50, which are moving right, to a rest position with elastic force.
According to the hair cutting rolling brush provided by the invention, the sectional type first hair cutting section 40 and the sectional type second hair cutting section Mao Duan are adopted, the arrangement of the hair cutting sections, namely the first hair cutting section 40 and the second hair cutting section Mao Duan are arranged in a staggered mode on the plane, the length relation between the first hair cutting section 40 and the second hair cutting section Mao Duan and the roller 10 enables windings to form tension pre-tightening on the hair cutting sections which are arranged in adjacent staggered mode along the axial direction of the roller 10, the windings are pulled to the cutting section Mao Duan, the windings are cut off more conveniently, and the cleaning effect is further improved. In addition, the blades on the first and second hair-cutting sections 40 and Mao Duan do not penetrate through one side of the drum 10, and the windings can pass through the position where the blades are not arranged so as to be sucked into the cleaner, so that the windings can be effectively prevented from being blocked between the blades and the drum shell.
