Description

Double-cam self-locking type foot bottom massager

Technical Field

The invention relates to a foot massager, in particular to a seven-acupoint foot massager with double cam shafts and self-locking function, and belongs to the technical field of medical instruments.

Background

In ancient times, people work with bare feet on the land all day, and the soles of the feet are in direct contact with the ground, so that the feet are stimulated to promote circulation, and then sweat to drink water, so that normal metabolism circulation is completed, and the healing function of the human body is exerted. The most effective way to remove toxins due to the erosion of organs by toxins is to accelerate the circulation of blood, which drives the toxins out of the excretory organs of the body. The blood circulation is accelerated, and the best method is the foot massage. The sole massage method is to massage the reflecting zone of the pathological organ or gland in a stimulation way to restore the original function of the pathological organ or gland, thereby achieving the effect of treatment. The foot massage machine simulates a massage manipulation technique through mechanical motion, and the massage manipulation technique mainly adopts a kneading method, a moving method, a rubbing method, a pushing method, a vibrating method, a tapping method and the like to perform pressing, scratching, rotating and other motions on the surface of the foot.
