Description

A dual-frenquency transducer for medical science and beauty

Technical Field

The utility model relates to a transducer especially relates to a dual-frenquency transducer for medical and beauty.

Background

The ultrasonic transducer can emit a wave shape which is alternately dense and can propagate to the surrounding medium, and the energy of the wave shape is stronger than that of a general sound wave. It has the characteristics of high frequency, good directivity, strong penetration capability, large tension and the like. When the ultrasonic wave acts on the skin of a human body, the blood circulation of the skin can be accelerated, and the metabolism is promoted.

Ultrasonic beautifying is to generate ultrasonic waves with a certain power intensity of tens of thousands to millions of hertz by an energy converter, and when the ultrasonic waves are mechanically vibrated, the ultrasonic waves act on the skin to vibrate cells and tissues along with the ultrasonic waves, so that a mechanical massage effect, a warming effect and a physicochemical effect are generated, the metabolic capability and the movement capability are improved, the capability of supplementing energy and water from external or internal tissue fluid is improved, and the ultrasonic beautifying can also break up the stack formed by garbage metabolized by the cells of the tissues and unclean particles in the air on the surface of the skin, so that the skin is healthy, tender, not loose, and has the effect of vitality and the like.

When the ultrasonic beauty instrument is actually used for beauty treatment, the effects of different people are not the same in the same ultrasonic beauty instrument. The selected ultrasonic frequency and power intensity have different effects on different skin conditions. In order to supplement energy and water to cells efficiently, the most effective method is to resonate the cells by ultrasonic waves of different frequencies, so that the exchange of energy and water can be performed most sufficiently. For example, water molecules absorb ultrasonic waves at extremely high frequencies most easily, and thus, for water-deficient skin, high frequencies are selected for use. For sensitive skin, the interstitial fluid is not made too active and low frequency ultrasound is required to make the skin viable.

Referring to fig. 1, the conventional ultrasonic beauty instrument includes a transducer 100 and a working head 200, the power intensity of the transducer 100 can be generally adjusted, but the frequency of the transducer cannot be changed. Even if different frequencies are realized by using the higher harmonics of the transducer, the frequency span is low, the application value is not large, so that different ultrasonic transducers need to be replaced when cosmetic operation is carried out on different crowds or different skin parts in actual use, the efficiency is low, operators need to switch equipment for many times, and much trouble is brought to actual application. Different effects of low and high frequencies on the human body: the low-frequency vibration is slow, the device is suitable for sensitive skin or needs to be used for deep cleaning, the high-frequency vibration frequency is high, and the device has good drug guiding and penetrating effects.

In addition, the transducer 100 of the existing ultrasonic cosmetic instrument is bonded with the working head 200, the vibration generated by the transducer is transmitted to the working head, the ultrasonic cosmetic instrument can realize different frequencies by using the higher harmonic wave of the transducer, for example, the 20K transducer can have several frequencies of 40K and 80K at the same time, but the higher harmonic wave has weak energy and large attenuation; however, only one transducer can be bonded on one working head, and only one frequency exists; and when the transducer is bonded in the mode of continuously working at high power, the working head generates heat seriously, the transducer and the working head can fall off, and the service life of the transducer is short.
