Description

Fascia gun

Technical Field

The invention relates to a health-care apparatus, in particular to a fascia gun.

Background

The fascial gun can be used for massaging parts with small contact surfaces, such as neck, shoulder, arm, achilles tendon, sole and the like, and can even be used for massaging small muscles and other soft tissues in a joint socket; the fascial gun can be used to massage a wider range of areas on the front and sides of the human body than a massage chair. The massage head is adopted for beating, the beating frequency is about 300 times per minute, and the amplitude is about 10 mm. However, because the hitting frequency is high, a single position cannot be massaged for a long time when the massager is used, otherwise muscle tissues are easily damaged, particularly, when bones such as the spine are massaged, the pressure cannot be too high, but the nearby spine is massaged by using light strength, and dizziness can be caused by a high-frequency hitting mode for a long time. Therefore, the fascia gun is not designed for continuous operation for a long time, but many non-sporters, such as a group who sits for a long time and stands for a long time, namely keeps a posture, also use the fascia gun to massage the whole body to relieve the ache and the discomfort. However, the fascia gun has small volume and large heat productivity, is long in massage time for the whole body, and particularly can smell the taste of plastics when being used for a long time for the fascia gun with low quality, thereby generating potential safety hazard.
