Massage driving mechanism and massage gun

Abstract

The invention belongs to the field of massage equipment, and particularly discloses a massage driving mechanism capable of changing the amplitude and a massage gun comprising the massage driving mechanism. An eccentric wheel assembly of the massage driving mechanism is mainly composed of a lower eccentric wheel, an upper eccentric wheel, a gear and a movable shaft seat, the movable shaft seat with an eccentric shaft is meshed with the gear through a rack on the lower portion of the movable shaft seat, and the movable shaft seat can move between a first limiting part and a second limiting part in the tooth contour line direction of the rack. The eccentric distance e1 of the eccentric shaft is not equal to e2 when the movable shaft seat is in the forward and reverse rotation locking state, so that the amplitude A1 generated by a piston rod is not equal to A2 when the motor rotates forwards and reversely, the requirements of customers for different massage depths when different positions are massaged can be met, the massage effect is ensured, and the user experience is improved.

Description

Technical field [0001] The present invention belongs to the field of massage, and more particularly to a massage drive mechanism and a fascia gun. Background technique [0002] The fascia gun, also known as the deep muscle microscopy, is a soft tissue massage tool that relaxes the body's soft tissue by high frequency impact. The existing brilliance gun drives the massage drive mechanism to reciprocate the backfinder, massage the head and the human body, generate high frequency vibration to the deep layer of muscles, to reduce local tissue, relieve pain, promote blood circulation, etc. . [0003] The existing massage drive mechanism is mainly made of a motor, an eccentric wheel disposed on the output of the motor, and a transmission arm that hinges and the eccentric shaft of the eccentric wheel, and a piston rod hinged to the other end of the transmission arm. The motor is used to drive the eccentric wheel, the drive arm, the piston rod, and the massage head in the process of the ...

Problems solved by technology

[0004] However, the existing massage drive mechanism is a fixed eccentric shaft, and the eccentricity cannot be adjusted. For example, for a massage drive mechanism with a striking distance of 8mm, its motor has the same striking distance when it is forward and reverse. In larger cases, the position with fewer muscles will feel pain, and in the case of smaller hitting distance, the massage effect will not be much greater when the area with more muscles is hit, so it is far from satisfying customers when massaging different positions. The need for different amplitudes of the fascia gun
