[0002] The existing reciprocating electric shaver has only one head, which is connected to the gear by the motor, through the shaft in the gear or directly connected to the transmission device of the reciprocating parts. Although the existing rotary electric shaver has three or five The head is formed, but the head cannot move away from the connection part and the support point, and can only swing a little in the position of the connection part and the support point, and the swing is only the center of the connection part of each head in the electric shaver. The gap between the large gear and the small gear in the head is produced by the

Abstract

The invention provides a transmission device of an electric shaver with included angles formed between movement directions of a head. The head is formed by movable hinging of two or more identical head shells which are arranged into certain shapes such as a straight line and a triangle. Each head shell is provided with a gear set. A through hole is formed in a shaft of one gear in each gear set, wherein a transmission shaft is movably connected in the through hole in a sleeved mode, a flexible transmission shaft is fixedly connected with one end of the transmission shaft, and the other end of the flexible transmission shaft is fixedly connected with a shaft of a gear in a gear set arranged in the middle of a guiding frame arranged in the electric shaver with included angles formed between movement directions of the head. A flexible transmission shaft is fixedly connected with one end of a shaft of the other gear of the gear set arranged in the middle of the guiding frame, wherein the other end of the flexible transmission shaft is fixedly connected with a transmission shaft which is movably connected with another transmission shaft, fixedly connected with another gear set, in a sleeved mode, and the another gear set is fixedly connected with a motor. The transmission device is simple in structure and stable in high-speed rotation.

Description

technical field [0001] The present invention relates to an electric shaver, in particular to a transmission device for an electric shaver. Background technique [0002] The existing reciprocating electric shaver has only one head, which is connected to the gear by the motor, through the shaft in the gear or directly connected to the transmission device of the reciprocating parts. Although the existing rotary electric shaver has three or five The head is formed, but the head cannot move away from the connection part and the support point, and can only swing a little in the position of the connection part and the support point, and the swing is only the center of the connection part of each head in the electric shaver. The backlash is created by the meshing of the large gear and the small gear in the head. It is also a transmission device that is driven by a motor connected to a gear or a shaft, or a shaft connected to a gear or a movable shaft. These existing reciprocating,...
