Embodiment 1

[0030] figure 1 Schematically provides the structural diagram of the hair collection device of Embodiment 1 of the present invention, as figure 1 Shown, the collection device of described hair comprises:

[0031] Support, the first cutter head 141, the second cutter head 142, the first motor 15 and the battery 17, the battery 17 supplies power for the first motor 15 and the second motor 17; these are all prior art in the electric hair clipper;

[0032] A cylindrical part 11, the cylindrical part 11 is fixed on the bracket, the cylindrical part 11 has a first open end 111 and a second open end 112, and the first open end 111 faces toward the second A side of the cutter head 142 facing away from the first cutter head 141;

[0033] Retention part 19, such as figure 2 As shown, the retaining member 19 is arranged at the second open end of the cylindrical member, the retaining member allows the passage of gas, and retains the hair;

[0034] An extracting unit, the extracting u...

Embodiment 2

[0052]An application example of the hair collection device and method according to Embodiment 1 of the present invention.

[0053] In this application example, if figure 1 As shown, the first cutter head 141 is a fixed cutter head, the second cutter head 142 is a moving cutter head, and the first motor 15 drives the second cutter head 142, thereby cutting off the first cutter head 141 and the second cutter head. 142 hairs;

[0054] Such as Figure 1-2 As shown, the section perpendicular to the central axis of the cylindrical part 11 is an isosceles trapezoid with rounded corners, and the second open end 112 is provided with a retaining part 19, and the retaining part adopts a stainless steel filter screen, which allows the passage of air, but traps hair; The cylindrical part 11 is stuck on the bracket through the slide groove; the projection of the upper end of the second cutter head 142 on the first plane falls within the projection of the cylindrical part 11 on the first p...

Embodiment 3

[0062] According to the application example of the hair collecting device and method of Embodiment 1 of the present invention, the difference from Embodiment 2 is:

[0063] The distance adjustment unit is no longer arranged on the linear guide rail, but is arranged on the rotating shaft, and the rotating shaft is arranged on the bracket; the nut is fixed on the rotating shaft, thereby fixing the distance adjusting unit on the bracket;

[0064] The angle of the distance adjustment unit relative to the bracket is adjusted and fixed by a nut, thereby adjusting the distance between the distance adjustment unit and the second cutter head.
