Problems solved by technology

[0002] Electric hair clippers are consumer products favored by families. At present, electric hair clippers in the industry are usually equipped with a body assembly, and the end of the body assembly is provided with a cutter head assembly. It swings in a straight line to cut hair. In the straight-line shearing swing, since the blades of the two knives move towards each other during the movement, when the pressing between the moving knife assembly and the static knife is not tight, it is easy to produce hair loss. Hair pinching and curling occur. In order to avoid this situation, manufacturers usually increase the clamping force between the moving knife assembly and the static knife to avoid a gap between the two knives, but the increase of the clamping force also Increase the swing friction of the moving knife assembly and increase the power loss of the power unit, which will cause problems such as motor load work and power consumption increase

Embodiment 1

[0029] The invention provides an arc swing electric hair clipper, such as Figure 1 to Figure 7 , including a body assembly 1 and a cutter head assembly 2 cooperating with the body assembly 1, the body assembly 1 is provided with a power unit 3 for driving the cutter head assembly 2, and the cutter head assembly 2 includes a moving knife assembly 21 and the static knife 22, the moving knife assembly 21 is provided with a rotating shaft 218 and a driving part 217, the rotating shaft 218 is hinged on the body assembly 1, and the rotating shaft 218 is relatively to the static knife 22 and the The position of the body assembly 1 is fixed, the line connecting the center of the rotating shaft 218 and the center of the driving part 217 coincides with the center line of the moving knife assembly 21, and the power unit 3 drives the driving part 217 so that The moving knife assembly 21 swings around the rotating shaft 218 so that the moving knife assembly 21 swings and cuts in an arc re...

Embodiment 2

[0037] In this example, if Figure 8 and Figure 9 , the tail of the driving member 211 is provided with a steering part 210 extending backward, and the rotating shaft 218 is arranged on the steering part 210, and the rotating shaft 218 protrudes toward the body assembly 1, and the rotating shaft 218 The axis (axis b) is perpendicular to the centerline c of the body assembly 1 . In this embodiment, the tail of the driving member 211 is provided with a turning part 210, so that the rotation axis (axis b) of the rotating shaft 218 is perpendicular to the centerline c of the body assembly 1, so that the moving knife assembly 21 is at the front end of the body assembly 1 Perform arc swing around the center line c of the body assembly 1. The end faces of the moving knife assembly 21 and the static knife 22 away from the body assembly 1 can be formed into an arc surface, so that the moving knife assembly 21 swings in an arc surface. In this embodiment The movable knife assembly 21...

Embodiment 3

[0039] The difference between this embodiment and Embodiment 1 is that, if Figure 10 , in this embodiment, the connecting plane 225 of the static knife 22 is provided with a shaft hole 12, and the rotating shaft 218 is installed in the shaft hole 12, so that the moving knife assembly 21 and the static knife 22 are assembled into a cutter head Assembly 2, the cutter head assembly 2 is integrally assembled on the body assembly 1 . The shaft hole 12 is arranged on the static knife 22, and the rotating shaft 218 of the driving member 211 is installed in cooperation with the shaft hole 12 on the static knife 22, so that the moving knife assembly 21 rotates around the rotating shaft relative to the static knife 22. 218 arc swing. In this embodiment, the shaft hole 12 is set on the connection plane 225 of the static knife 22, so that the knife head assembly forms an assembled whole, and the knife head assembly can be disassembled and assembled from the body assembly as a whole, whi...

Abstract

The invention provides an arc swing electric hair clipper. The arc swing electric hair clipper comprises a body assembly, and a tool bit assembly mounted in cooperation with the body assembly, a powerunit capable of driving the tool bit assembly is arranged in the body assembly, the tool bit assembly comprises a movable tool assembly and a fixed tool, a rotating shaft and a drive part are arranged on the movable tool assembly, the connecting line of the center of the rotating shaft and the center of the drive part coincides with the centre line of the movable tool assembly, the power unit drives the drive part, the movable tool assembly swings around the rotating shaft, and the movable tool assembly is in arc swing clipping relative to the fixed tool. The arc swing electric hair clipper achieves swing friction, avoids hair clipping and has the excellent clipping effect.

Description

technical field [0001] The invention relates to the field of hand-held cutting tools, in particular to an arc-swing electric hair clipper. Background technique [0002] Electric hair clippers are consumer products favored by families.
