Introduction of electric massager and matters needing attention

Electric massager products make up for the defects of traditional tools and the limitations of manual massage, and also provide a variety of personalized choices to help you choose the right products according to the actual situation, and help to ensure the excellent effects and advantages in the later period. Then the knowledge introduced today is about the functional advantages of electric massager and the analysis of the situations that are easy to encounter during use, including matters needing attention and so on. You can refer to learning to understand.

Introduction of electric massager

The electric massager is a kind of health-care appliance that uses the built-in battery or power supply to push the massage head to vibrate and massage the human body. Massage is conducive to relaxing muscles and tendons, promoting blood circulation, eliminating fatigue and preventing diseases.

The electromagnetic massager is mainly composed of iron core (including fixed iron core and movable iron core), coil, vibrating spring leaf and massage head. When alternating current is applied to the coil on the fixed iron core, an alternating magnetic field is generated, and the massage head vibrates repeatedly under the action of the magnetic field force and the vibrating spring piece. The vibration frequency is generally 100Hz and the input power is10 ~15 w. The methods to change the vibration intensity are as follows: first, change the core gap or current intensity; Second, change the vibration frequency. Motor massager is mainly composed of motor, spring shaft, spring, eccentric wheel and massage head. The motor drives the eccentric wheel to rotate at high speed through the spring shaft, and the eccentric wheel makes the massage head vibrate.

Second, the working principle of electric massager and matters needing attention

1, the working principle of electric massager

Simply put, the electromagnetic massager is mainly composed of an electromagnetic wire core and a coil. When the coil is excited by 50Hz alternating current, an alternating magnetic field is generated. The alternating magnetic field changes from small to large, which drives the iron core to vibrate and then transmits the vibration to the massage head. Because China uses 50Hz alternating current, the vibration frequency of the massage head is 100Hz.

The vibration source of electric massager is motor. Generally speaking, the motor of massager is a permanent magnet micro DC motor. The working principle of the massager is that the rotation of the motor spindle is transmitted to the eccentric wheel through the coupling spring, and the eccentric wheel is used to convert the rotation of the motor into reciprocating motion and transmit the reciprocating motion to the vibrating head. Since the motor speed is 5000 ~ 10000 rpm, the vibration frequency of the electric massager is also per minute.

2. Use precautions

The operation of the electric massager should be carried out in strict accordance with the product manual. In addition, the following points should be noted:

1. If there is no vibration, smoke and other abnormal conditions during use, immediately turn off the switch, unplug the power plug, and then use it after troubleshooting.

2. It is advisable to massage for no more than half an hour each time. If you feel uncomfortable during massage, you should stop using it.

3. Use the massager with 220V AC, and pay attention to the safety of electricity when operating; The massager can't be hit and damp, and water can't splash on the massager.

4. Some patients, such as tumors, fractures, skin diseases and infectious diseases, should not use electric massagers.

3. What does "the electric massager can be used for 20 minutes at most" mean?

The elderly should pay attention to the following points when using massagers: First, choose electric massagers with fast vibration frequency and weak vibration intensity, while electromagnetic massagers are more suitable for middle-aged and young people because of their slow vibration frequency and strong vibration intensity. Second, the use time should not be too long, and the intensity and frequency of massage should be adjusted from light to heavy and from less to more. It is best to control each time at about 20 minutes, morning and evening 1 time. The third is to pay attention to the use method. The arm holding the massager should be flexible, not too tight, and the vibrating head should not press the skin tightly.

The information introduced above includes the matters needing attention in using electric massagers, as well as their functional advantages and characteristics. In addition, we also analyzed the explanation of "don't practice with electric massager for more than 20 minutes" in the market, so as to help friends who have doubts about this to master accurate knowledge, thus ensuring the actual effect advantage in the later period. So we can know that the electric massager can help everyone enjoy high-quality massage service anytime and anywhere, thus relieving fatigue.
