Description

Technical Field

[0001] The utility model belongs to the technical field of fascia guns and relates to a kneading transmission structure and an electric fascia gun adopting the kneading transmission structure. Background Art

[0002] A fascia gun, also known as a deep myofascial impactor, is a soft tissue rehabilitation tool that mainly relaxes the body's soft tissues through high-frequency impacts. The structure of a fascia gun is mainly composed of a main unit and a handle, and a motor and other power components are installed in the main unit. At present, common fascia guns mostly use a crank-connecting rod transmission structure to achieve high-frequency vibration to impact the deep myofascia. This type of fascia gun cannot achieve local muscle kneading, and fascia guns in the prior art mostly achieve muscle heat compress by heating the massage ball with electric heating, which consumes a lot of energy. Therefore, it is necessary to design a structure that can achieve muscle massage and hot compress with a massage ball without an electric heating mechanism.

[0003] For example, a Chinese patent discloses a fascia gun [application number: 202110320826.6], comprising a body and a massage head connected to the body, wherein: the body comprises: a magnet, arranged at one end of the body connected to the massage head, for generating a magnetic field; a controller, electrically connected to the motor, for controlling the rotation of the motor; the motor, for rotating under the control of the controller, so as to drive the massage head to perform reciprocating motion by rotation; the massage head comprises: a coil, arranged in the massage head, for generating an induced voltage and / or an induced current based on electromagnetic induction when the massage head performs reciprocating motion; a working circuit, electrically connected to the coil, for working based on the induced voltage and / or induced current generated by the coil.
