detailed description

Referring to Figures 1 and 2, a roller-type roller brush hair removal mechanism of the present invention includes a roller brush 1 and a first driving device 6, the roller brush 1 including a roller brush bar 11 and a roller bar 11 The tufting bundle 12 of the central surface of the outer surface of the planting area 111 further includes a depilatory barrel 2 disposed side by side with the brush bar 11, the planting area 111 is provided with a groove 112, and the groove 112 is in the roll The entire hair-planting area 111 is passed through in the direction of the axis of the brush rod 11, and the hair removal barrel 2 is provided with a convex blade 21 matched with the groove 112; the first driving device 6 drives the roller brush 1 Rotating together with the hair cartridge 2, the hair removal cylinder 2 is opposite to the rotation direction of the roller brush 1, and the convex blade 21 is engaged with the groove 112. When the ground cleaning device of the hair removal mechanism of the present invention is required to perform a cleaning operation, the first driving device 6 is caused to drive the roller brush 1 and the hair removal cylinder 2 to rotate by activating the work button, and when there is foreign matter such as hair, When the circumferential direction of the brush bar 11 is wound around the planting area 111, foreign matter such as hair will be crushed and cut off from the roller brush 1 due to the engagement of the groove 112 and the convex blade 21, and since the groove 112 is rolled The brush rod 11 passes through the entire planting area 111 in the axial direction, so that foreign matter such as hair wound around the planting area 111 in the circumferential direction of the roller bar 11 can be broken by the convex blade 21, plus the existing floor cleaning device. Basically, it is equipped with a vacuum cleaner, and foreign matter such as falling hair will eventually be sucked away by the vacuum cleaner, thereby achieving the purpose of automatically removing foreign matter such as hair without stopping the machine during cleaning.

Referring to FIGS. 1 and 3, in order to further remove foreign matter such as hair wound around the tufting bundle 12, in the present embodiment, specifically, a hair-growing strip 7 provided with bristles 71 toward the side of the roller brush 1 is further included. Driving a second driving device 9 of the hair grafting strip 7 moving between a position near the roller brush 1 and a position away from the roller brush 1; the roller brush 1 is rotated and the planting strip 7 is located close to the When the position of the brush 1 is rolled, the tufting bundle 12 and the bristles 71 are combed. When the foreign matter such as hair is wound around the tufting bundle 12 of the roller brush 1, the hairdressing strip 7 is driven by the second driving device 9 to move toward the position close to the roller brush 1, and then the hair is combed by the pair of the tufting bundle 12 and the bristles 71. The foreign matter is combed from the tufting bundle 12; in addition, the existing floor cleaning equipment is basically equipped with a vacuum cleaner, and the foreign matter such as the fallen hair is finally sucked away by the vacuum cleaner, thereby automatically removing foreign matter such as hair without stopping the machine during cleaning. The purpose of the second driving device 9 is to move the hair grafting strip 7 to a position away from the roller brush 1 and to make the bristles 71 and the tufting bundle 12 out of contact with each other after the foreign matter such as hair on the tufting bundle 12 is removed. It is avoided to bring too much resistance to the rotation of the roller brush 1, thereby affecting the cleaning operation.

In the process of removing foreign matter such as hair by the bristles 71 on the tufting strip 7, foreign matter such as hair is likely to be directly transferred to the bristles 71 as the bristles 71 and the tufts of the tufts 12 are combed, and hair may be used after a long period of use. The risk of a large amount of foreign matter accumulating on the bristles 71; therefore, in order to avoid the above-mentioned situation, in the present embodiment, in particular, a fixed grid 8 is disposed between the roller brush 1 and the hair-powder strip 7, the planting strip 7 in the process of being close to or away from the roller brush 1, the bristles 71 pass through the fixed mesh 8, so that even if foreign matter such as hair is transferred to the bristles 71, the fixed mesh 8 is scraped from the bristles 71. Next, and then sucked away by the vacuum cleaner provided on the floor cleaning equipment.

In the present embodiment, in order to drive the hair grafting strip 7 to move away from the position of the roller brush 1, in particular, the second driving device 9 includes a position for driving the hairdressing strip 7 to automatically reset to a position away from the roller brush 1. The first elastic return structure 91 is described. Also, preferably, the first elastic returning structure 91 is a first compression spring, and the first compression spring is mounted between the fixed mesh 8 and the flocking strip 7. Of course, according to the actual situation, in addition to the first compression spring, the first elastic return structure 91 may also adopt other types of elastic elements such as rubber bands and tension springs. At the same time, in order to drive the tufting strip 7 to move closer to the position of the roller brush 1, in particular, the second driving device 9 further includes a first oblique slider 92 fixedly connected to the tufting strip 7, pushing the first The inclined slider 92 is moved toward the second oblique slider 93 in the direction of the roller brush 1, and the first oblique slider 92 and the second oblique slider 93 are provided with a first inclined surface and a second inclined surface that cooperate with each other; When the foreign matter such as hair is needed to be cleaned, the second oblique slider 93 can be pushed by a manual or electric method, and the first oblique slider 92 is pushed by the second oblique slider 93 to drive the planting strip 7 together to approach the roller brush 1 . The direction of movement.

In order to enable the second oblique slider 93 to be automatically reset in the same manner, in the embodiment, the second driving device 9 further includes a second elastic reset structure 94. The second elastic return structure 94 drives the second oblique slider 93 to be reset to a side away from the first oblique slider 92.
