Abstract

The utility model belongs to the technical field of reciprocating electric shavers, and relates to a middle knife movable knife driving structure of a reciprocating electric shaver. The reciprocating linear motion of the middle knife moving knife is not driven by the driving head of the main machine but driven by the circular knife fixing frame. The bulges are arranged on the circular knife fixing frame, the middle knife driving head is coupled with the bulges, and the bulges directly drive the middle knife driving head to make the middle knife driving head do reciprocating linear motion which is the same as that of the circular knife fixing frame, so that the middle knife is driven to do reciprocating linear motion, and the motion stroke is the same as that of the circular knife.

Description

Intermediate knife moving knife driving structure of reciprocating electric shaver

Technical Field

The utility model relates to a middle knife moving blade driving structure of a reciprocating electric shaver. Belongs to the technical field of reciprocating electric shavers.

Background

In the prior art, reciprocating electric shavers are divided into a linear reciprocating type, a parallel swing reciprocating type and a vertical swing reciprocating type according to the working mode of a main machine driving head.

In the linear reciprocating type and the parallel swing reciprocating type, the reciprocating linear motion of the middle knife moving knife and the circular knife is directly driven by the driving heads which are in one-to-one correspondence on the main machine, and the reciprocating strokes of the middle knife moving knife and the circular knife are the same.

In the vertical swing reciprocating type, the main machine driving head swings left and right by taking one shaft as a circle center, and the working plane of the main machine driving head is vertical to the working planes of the middle knife moving blade and the circular knife. In the driving mode, the circular knife of which the working plane is far away from the swinging circle center can be directly driven by the main machine driving head, but the middle knife moving knife of which the working plane is close to the swinging circle center or is superposed with the swinging circle center cannot be driven by the main machine driving head, because the closer to the swinging circle center, the smaller the stroke is, and the zero is.

SUMMERY OF THE UTILITY MODEL

The utility model provides a structure capable of driving a movable blade of a middle blade in a vertical swing reciprocating type electric shaver. The whole structure is simple, and the use performance is stable and reliable.

In order to achieve the purpose, the technical scheme of the utility model is as follows:

a middle knife moving knife driving structure of a reciprocating electric shaver comprises a circular knife fixing frame, a circular knife, a middle knife driving head and a middle knife moving knife. The reciprocating linear motion of the middle knife moving knife is not driven by the driving head of the main machine but driven by the circular knife fixing frame. The circular knife fixing frame is provided with the protrusions, the middle knife driving head is coupled with the protrusions, and the protrusions directly drive the middle knife driving head to make the middle knife driving head do reciprocating linear motion the same as that of the circular knife fixing frame, so that the middle knife is driven to do reciprocating linear motion, and the motion stroke is the same as that of the circular knife.

The utility model relates to a driving structure of a reciprocating electric shaver middle cutter moving cutter, which realizes the work of vertically swinging the reciprocating electric shaver middle cutter moving cutter, and has simple whole structure and stable and reliable use performance.

Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Example 1:

referring to fig. 1 to 4, a driving structure of an intermediate cutter of a reciprocating electric shaver includes a circular cutter holder 2, a circular cutter 3, an intermediate cutter driving head 4 and an intermediate cutter moving cutter 5. The circular knife fixing frame 2 is provided with a protrusion 1, the protrusion 1 is a cylindrical object, and the protrusion 1 is coupled with a groove on the movable knife driving head 4. When the main machine driving head 6 does left-right circular arc swing by taking the swing shaft 7 as a circle center, the main machine driving head 6 drives the circular knife fixing frame 2 to enable the protrusion 1 and the circular knife 3 to do left-right reciprocating linear motion together, and the middle knife driving head 4 coupled with the protrusion 1 also does the same reciprocating linear motion under the driving of the protrusion 1, so that the middle knife 5 does the same reciprocating linear motion as the circular knife 3.

Example 2:

referring to fig. 1-4, the protrusion 1 is two columns, and the protrusion 1 is coupled with the column on the moving blade driving head 4, so as to realize the reciprocating linear motion of the middle blade 5 with the same stroke as the circular blade 3.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, and the scope of protection is still within the scope of the utility model.
