Massage device

Abstract

A massage device comprising an output shaft, a plurality of permanent magnets arranged on the output shaft, and an electromagnetic driving module arranged radially outside the permanent magnets. The stator yoke of the electromagnetic driving module and the permanent magnets interact to generate a cogging torque. The electromagnetic driving module interacts with the permanent magnets to generate anelectromagnetic driving force. The massage device has improvements in efficiency and output, is compact and reduces heat generation. The activation of the electromagnetic driving module actuates theoutput shaft to strike forward. The cogging torque applies a first pulling force to the output shaft to provide braking and buffering to the output shaft. When the output shaft is urged to move in thedirection opposite to the strike forward direction from the idle state, the cogging torque applies a first thrust to the output shaft, to thereby increase the output.

Description

technical field [0001] The invention relates to a massage device, in particular to a massage device suitable for massaging human muscles, meridians, specific acupoints or specific sore points, or an impact vibration device for human bones. Background technique [0002] There are a variety of massage devices on the market to suit various needs, such as massage chairs that can massage the entire back and neck, foot massage devices that can massage the calf to the entire foot, and massage guns that can target specific acupoints or specific soreness Click for a massage. [0003] Furthermore, related known technologies about massage guns include Chinese Taiwan Patent Announcement Nos. M343481, M446632, and No. M508318 new patents, and Chinese Taiwan Patent Publication No. 201440753 Invention Patent, wherein No. M343481 patent uses a motor to drive the crankshaft to achieve reciprocating impact. effect, but the impact effect of the crankshaft is not obvious, and the output force ...

Problems solved by technology

[0005] However, as far as the prior art in the last three chapters is concerned, the output force depends on the electromagnetic force of the output shaft and the solenoid valve coil. The operation of the output shaft only uses electromagnets and does not use permanent magnets, so the efficiency is poor. And it is easy to heat up. In addition, the end of the output stroke of the output shaft must be buffered by a spring, and the output shaft must be driven to reset by the spring. However, the spring will inevitably reduce the consumption of part of the output, resulting in unnecessary energy consumption, and the spring will There are life and noise problems, and it also increases the complexity of the mechanism
