[0002] A knee massager is a device that can massage and care for the knees, mainly used to relieve symptoms such as knee pain, stiffness and fatigue. Knee massagers usually use a variety of massage techniques, such as vibration, air bags and pulses, to provide deep relaxation and relief. In addition to massage techniques, knee massagers usually also have a heat function, which can dilate blood vessels and increase blood circulation, further relieving knee pain and stiffness.

[0003] Current knee pad massagers mainly achieve heating effect by embedding a heating film or heating wire inside the knee pad and using electric current to generate heat. The heating wire or heating film is usually directly set inside the knee pad cloth. After long-term use, if the heating wire or heating film is damaged, the heating mechanism cannot be replaced, resulting in damage to the knee pad massager and inability to use. On the other hand, existing knee pads usually use heating films or heating wires for heating, which will generate electromagnetic radiation while heating, and there will be a certain probability of electric shock risk, and the temperature control is not uniform enough. Therefore, a heating mechanism of a knee pad massager is proposed to solve the above problems. Utility Model Content
