Description
Technical Field
The invention relates to the field of radio frequency beauty treatment instruments, in particular to a household radio frequency beauty treatment instrument with a variable polar distance.
Background
Radio frequency is an electromagnetic wave with high frequency alternating current change, and is a novel noninvasive beauty treatment technology following laser and photons. In recent years, with the rapid development of the medical beauty industry, radio frequency skin tightening frequency is promoted by beauty-seeking people and becomes a pet for resisting aging in the heart of many people. As a high-frequency electromagnetic wave, the radio frequency is between 300KHz and 300GHz, and the high-frequency electromagnetic wave can penetrate through the epidermal layer, heat collagen in the dermal layer and stimulate the growth of the collagen, thereby achieving the effects of lifting and firming the skin and reducing wrinkles.
Medical and aesthetic radio frequency technologies can be classified into monopolar radio frequency, bipolar radio frequency and multipolar radio frequency according to the number of electrodes. The monopolar radio frequency is a radio frequency technology in which one radio frequency electrode directly contacts the face and the other radio frequency electrode is attached to the back of a user to form a closed loop, and the monopolar radio frequency has deeper penetration depth and stronger energy but the penetration depth cannot be controlled. The bipolar radio frequency means that two radio frequency electrodes are integrated on the beauty treatment head, and a closed loop is formed at the local position of the face of a user, so that the penetration depth is relatively shallow, and the safety is higher. In addition, multi-pole radio frequency technologies such as tripolar, quadrapole, pentapolar, etc. are also publicized in many beauty instruments on the market, and all of these technologies are combinations of multiple bipolar radio frequencies.
The penetration depth of the bipolar radio frequency on the skin of the human face can be accurately adjusted by controlling three parameters of driving voltage, frequency and polar distance. The driving voltage determines the effective depth to which the rf energy can be delivered subcutaneously, with higher driving voltages and greater rf energy resulting in greater penetration depths. The frequency refers to the speed of change of the radio frequency waveform, and the higher the frequency is, the shallower the penetration depth is. The polar distance refers to the distance between two radio-frequency electrodes, and the penetration depth is equal to about half of the polar distance. The existing bipolar radio frequency generally adopts a fixed frequency, a double frequency conversion and a triple frequency conversion mode to transmit radio frequency signals. The frequency emitted by the fixed-frequency household radio frequency beauty instrument in the treatment process is unchanged, one frequency can only heat one depth, but the depths of dermis layers of different people and different facial parts are different, and the fixed-frequency radio frequency technology cannot accurately heat dermis collagen. In the treatment process of the household radio frequency beauty instrument with double frequency conversion and three frequency conversion, radio frequencies with two or three frequencies are alternately transmitted, or two or three pairs of electrodes are used for respectively transmitting radio frequencies with different frequencies. The heating range can only be expanded to a certain extent by adjusting the radio frequency, the effect is very limited, and the comprehensive treatment from the superficial dermis to the deep dermis is difficult to realize. And the electrode polar distance of the existing radio frequency beauty instrument is set to be a fixed value in the production process, the electrode distance of the radio frequency emitted by the household radio frequency beauty instrument with the fixed polar distance is fixed in the treatment process, so that the heating range of the radio frequency is limited, the penetration depth of radio frequency energy is constant, and the effective heating can not be carried out according to different skin thicknesses.

Step 2: the treatment head of the radio frequency beauty instrument is tightly attached to the corresponding facial skin part. If the working mode is the periocular mode, the treatment head of the household radio frequency beauty instrument is tightly attached to the periocular skin. If the working mode is the perioral mode, the treatment head of the household radio frequency beauty instrument is tightly attached to perioral skin. If the working mode is the forehead mode, the treatment head of the household radio frequency beauty instrument is tightly attached to the forehead skin. If the working mode is cheek mode, the therapeutic head of the household radio frequency beauty instrument is tightly attached to the cheek skin.
And 3, step 3: the main control chip 41 outputs a low voltage value U in the current working mode, where U is less than or equal to 20V. Low voltage value in eye mode < low voltage value in mouth mode < low voltage value in forehead mode < low voltage value in cheek mode.
And 4, step 4: the transformer 42 converts the low voltage value into a high voltage. Assuming that the voltage transformation ratio of the transformer 42 is k, the high voltage is: u' = kU.
And 5, step 5: the main control chip 41 controls the switch to gate different positive and negative electrodes according to the current working mode. Wherein, the radio frequency signal that positive electrode launched is:
the radio frequency emitted by the negative electrode is:
omega is the angular frequency of the radio frequency signal,

Angular frequency of radio frequency signals in periocular mode<Angular frequency of radio frequency signal in perioral mode<Angular frequency of radio frequency signal in forehead mode<Angular frequency of the radio frequency signal in cheek mode.
As shown in fig. 7, assuming that the electrode pitch in the periocular mode is d, the penetration depth of the radio frequency is d/2. The electrode polar distance in the perioral mode is
The penetration depth of the RF signal is
The electrode polar distance in the forehead mode is 2d, and the penetration depth of the radio frequency signal is d. Electrode pole distance in cheek mode is

And 7, step 7: and transmitting the skin temperature measured by the 4 temperature sensors 7 back to the main control chip 41, and judging whether the skin temperature is higher than a safe temperature threshold value. The default safe temperature threshold is 42.5 ℃, and can be actually adjusted in a range of 42-45 ℃ according to the tolerance of a user.
If the 4 skin temperature values measured by the 4 temperature sensors 7 are all lower than or equal to the safe temperature threshold, the positive and negative electrodes 33 continue to output radio frequency. If 1 of 4 epidermis temperature values measured by 4 temperature sensors 7 is higher than the safe temperature threshold, the main control chip 41 starts the overtemperature buzzer 8 to prompt the user to move the therapy head in the therapy area.

Step 9: and (5) shutting down the machine.
The thickness of the skin of the face of a human body is influenced by a plurality of factors such as sex, age, skin type, position and the like, so that the depth of the dermis is not a fixed value. The principle of the radio frequency beauty technology for realizing anti-aging is to heat dermal collagen. If the RF energy does not heat the dermis accurately, the anti-aging effect is also compromised. Research shows that the penetration depth of radio frequency is related to three factors, namely driving voltage, frequency and polar distance. Wherein, the driving voltage is easy to cause the safety risk and can not be adjusted at will. The range of frequency to rf penetration depth adjustment is very limited. The polar distance is difficult to change under the influence of the manufacturing process of the treatment head. Therefore, the invention arranges a plurality of electrodes into a square matrix, only gates one part of the electrodes when emitting radio frequency, realizes the radio frequency technology of variable polar distance, can greatly expand the radio frequency heating range, and can realize effective anti-aging to the skin with different thicknesses.
The principles and embodiments of the present invention have been described herein using specific examples, which are provided only to help understand the method and the core concept of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed. In view of the foregoing, the description is not to be taken in a limiting sense.
