Working principle and function of ultrasonic introducer
This paper introduces the working principle of the scheme development of ultrasonic lead-in instrument; It is a kind of beauty that acts on human skin through sound waves. When an object vibrates mechanically, dense elastic waves will be generated in the air, and they will become sound in the ear. Generally, the vibration number is between 16-16000hz. When it exceeds 16000hz, the mechanical vibration wave that cannot cause normal hearing is ultrasound.
principle
It is a waveform that can be transmitted to the surrounding medium and transmitted through special instruments. It has the characteristics of high frequency, good directivity, strong penetration and high tension. When ultrasound acts on the human body, it will strengthen skin blood circulation and accelerate metabolism.
Ultrasonic inductor
function
1. It has mechanical function: the energy provided by ultrasound will cause cell vibration, so as to change the interior of skin cells and achieve the purpose of beauty;
2. It has warming effect: the sound energy of ultrasound can be transformed into heat energy, which is an endogenous heat without feeling to the skin to achieve the purpose of beauty;
3. It has physical and chemical effects: the resulting polymerization and depolymerization reactions can effectively penetrate the skin. Increase the efficacy of skin care products.
instructions
When using, first test whether it is connected to the instrument. After opening, drop a few drops of water on the ultrasonic probe. If there is a response, it indicates that the connection is correct.
1. Clean the facial skin before doing ultrasound;
2. Before opening the sound head, apply enough cream to prevent it from burning;
3. When the knob is set to zero or the energy output indicator is off, the probe has no energy output;
4. The sound head cannot output ultrasonic energy for a long time (more than 30 minutes) without finishing operation to avoid overheating and damage to the sound head;
5. Clean the probe after ultrasound.
