Description

A multifunctional massager

technical field

The invention relates to the technical field of massage tools, in particular to a multifunctional massager.

Background technique

Modern people have a fast-paced life, high mental stress, and irregular work and rest time, so poor sleep therapy often occurs. Those who are mild are not easy to fall asleep, and those who are severe can't sleep all night, which seriously affects people's daily life.

Studies have found that excessive stress activates the "fight or flight" physiological response in the human body: heart rate increases, blood pressure increases, and various stress hormones are released into the bloodstream, all of which lead to elevated blood lipids. In addition, when the pressure is too great, it is easy to overeat, smoke, and live a "couch potato" life. These unhealthy lifestyles will lead to an increase in bad cholesterol and a decrease in good cholesterol.

To control blood lipid levels, it is very important to learn how to reduce stress. Decompression methods mainly include relaxation exercises, activities such as massage and swimming can be a good way to relax the body and mind. Massage is divided into manual massage and instrument massage. Manual massage is relatively expensive and cannot be done by yourself. You can massage yourself, usually using a massager.

The Chinese patent application with the application number 201020197969.X discloses a solar facial massager, which includes a middle shell, a rolling tube, a handle and a microcurrent generating device, wherein the rolling tube is rotatably coupled to one end of the middle shell; The handle is fixedly connected to the other end of the middle shell; the micro-current generating device is arranged in the handle, which includes a first electrode, a plurality of second electrodes, a solar cell and a battery holder; When it shines on the solar cell, the solar cell will generate a microcurrent on the battery holder. When using it, the user holds the handle and touches the first electrode, and then makes the second electrode contact the skin of the human face. At the same time, the second electrode will have a micro-current through the human facial skin, and then the rolling tube can be rolled on the human facial skin to contact different parts of the skin, and the micro-current can be used to stimulate the blood circulation in the lymphatic parts and eliminate toxins. , to achieve the effect of beauty and health care.

The micro-current generating device of the massager above includes solar cells and battery holders. When there is light, the light shines on the solar cells, and the solar cells will generate micro-currents on the battery holders. The micro-currents generated in this way The magnitude of the current is unstable, and it needs to be used in a place with solar energy. However, it is impossible for the user to use the massager while irradiating the sun. In the hot summer, the user is even more unwilling to use such a massager.

Therefore, it is particularly important to design a massager that can control the generation of micro-current at any time, so that the massager can be used anytime and anywhere. In view of the fact that the user's frequency of use may be higher, adding other functions to the massager also becomes a problem. necessary.
