Description

A massage head with heating function and a muscle massager using the same

technical field

The invention relates to the technical field of vibration massage equipment, in particular to a massage head with heating function and a muscle massager using the same.

Background technique

Muscles often cause pain or spasm due to sports injuries or morbid reasons. Muscle tension is abnormal due to various reasons such as hemiplegia and spinal cord injury. Massage the corresponding muscles can treat, relieve or help the muscles return to normal. Traditional push-pull massage therapy is unstable due to the intensity lead to a reduction in the efficacy of the treatment.

Therefore, people provide sarcolemma massage equipment. The sarcolemma massage device disintegrates the diseased tissue and eliminates the cause of pain through vertical vibration of different frequencies and intensities. The working voltage is provided to the vibration drive motor structure, and the vibration drive motor structure drives the massage part to act on the muscle surface that needs to be massaged through the piston rod, so as to achieve the effect of deep massage.

If the massage part is heated during the massage, the muscle massager will not only relieve muscle fatigue, but also promote human blood circulation and increase the therapeutic effect and comfort of massage. The heating function of the existing muscle massager is turned on and off by a button switch. Although it can achieve the function of heating at the same time as massage, there are still many defects, such as:

1. When the user operates the muscle massager with one hand, the heating function cannot be turned on or off by pressing the switch with the thumb, resulting in inconvenience;

2. If you forget to turn off the heating function after use, the power of the muscle massager will be exhausted, and you will need to recharge it next time. In the worst case, the high temperature will cause flammable materials to burn, which will pose a greater safety hazard.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a massage head with heating function which can automatically turn on and off the heating function.

In order to achieve the above object, the massage head with heating function provided by the invention, the specific embodiments are as follows:

A massage head with heating function, comprising a massage head body and a cover body, the cover body and the massage head body are assembled to form a accommodating cavity, the bottom of the massage head body is provided with a connection base connected with a muscle massager, including :
