Description

technical field

[0001] The invention relates to the field of massagers, in particular to a driving device for a massager. Background technique

[0002] There are many types of existing massagers, among which the fascia gun is an essential equipment for anti-loosening massage, and its driving methods are also different. The general fascia gun uses a motor to drive the crankshaft, and the crankshaft drives the connecting rod to realize the fascia loosening. The expansion and contraction of the gun massage head makes the drive mechanism larger in the longitudinal direction, which is not conducive to the miniaturization of the product;

[0003] According to the above problems, designers have continuously optimized and improved, such as changing the traditional brushed motor to a brushless motor, greatly shortening the axial size of the motor, or changing the crankshaft and crank structure to the form of end face cam and pin head cooperation to achieve miniaturization , but the ...
