Description

Technical Field

[0001] The utility model relates to an electronic device, in particular to a radio frequency beauty instrument. Background Art

[0002] Radio frequency beauty instrument refers to a beauty instrument that uses radio frequency technology to operate. It has positive and negative electrodes, and the radio frequency energy is distributed and diffused between the electrodes. When the radio frequency beauty instrument is turned on, the radio frequency energy can act on the skin and heat the skin tissue to a suitable temperature, thereby achieving the effect of tightening the skin and achieving beauty and anti-aging effects.

[0003] When radio frequency current passes through human tissue, it generates a frequency of 2×10 6 ~3×10 6 The oscillating current of times / second will cause the water molecules in the human tissue between a group of electrodes to oscillate rapidly in an instant. During the oscillation process, they rub against each other or the surrounding medium, thereby generating a large amount of heat energy locally, heating the dermis through the Ohmic thermal effect. Because the temperature of the human dermis is relatively constant, the dermis layer at 40-50°C will cause the collagen fibers to contract tightly, and stimulate inflammatory cells to secrete fibroblast growth factors (FGFs). FGFs are a kind of polypeptide protein that can enter the cell membrane and promote fibroblasts to produce collagen, elastin and hyaluronic acid. This achieves the effect of treating skin sagging, improving wrinkles, shrinking pores, tightening and lifting skin tissue.

[0004] The radio frequency beauty device in the prior art is usually provided with a lifting mode and a stamping mode. After starting the lifting mode, the radio frequency beauty device is slid on the skin surface according to the technique diagram; after starting the stamping mode, the radio frequency beauty device is placed against a certain area on the skin surface, and after a few seconds, the radio frequency beauty device is removed and placed against another area on the skin surface until all areas are placed against each other to achieve the beauty effect. In the stamping mode, the temperature control (such as effectiveness) of the radio frequency beauty device is particularly important.

[0005] Chinese patent CN214074721U discloses a temperature-controlled radio frequency beauty device, which has a stimulation head in contact with the skin surface, a radio frequency generation module that provides radio frequency energy to the stimulation head, a control module for controlling the output state of the radio frequency generation module, a power module for supplying energy, and a temperature sensing module; when the temperature-controlled radio frequency beauty device is working, at least one electrode group in the stimulation head can contact the skin surface and receive radio frequency energy to generate radio frequency current for stimulating skin tissue, the temperature sensing module senses the surface temperature of the skin tissue in real time, the control module obtains temperature information from the temperature sensing module at a preset frequency, and compares the temperature information with a preset temperature threshold to adjust the output energy of the radio frequency generation module per unit time. In this case, the skin surface temperature detected by the temperature sensing module can be maintained at a suitable temperature, thereby achieving a good skin care effect.

[0006] When using a radio frequency beauty instrument to perform radio frequency beauty treatment on human skin, medical gel is usually used and applied to the skin surface. It has a protective effect, helps to moisturize, rejuvenate, whiten, and improve comfort, and also makes the skin cells heat more evenly. Although the gel used in the prior art is non-toxic, odorless and non-irritating, some sensitive skin will experience redness, swelling and allergies after using the gel. In addition, after the radio frequency beauty instrument is used in conjunction with the gel, gel residue is likely to remain on the lead electrode. If it is not cleaned in time or not cleaned thoroughly, it is easy to breed bacteria and cause skin sensitization risks. However, if the lead electrode is excessively cleaned and flushed, it will damage the lead electrode and shorten the service life of the electronic product. Utility Model Content

[0048] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0049] like Figure 2 As shown, this embodiment provides a radio frequency beauty instrument, including a conducting head component P1, a radio frequency component P2, a control component P3 and a power supply component P4.

The battery can be a lithium battery. In some embodiments, the power control module can also be provided with a charging component for charging the lithium battery.

[0051] In some embodiments, the first conductive head electrode or the second conductive head electrode can use a temperature-sensing conductive head electrode, which is a stainless steel electrode sheet and is provided with an installation cavity. A thermal conductive silicone grease layer is provided inside the installation cavity. The temperature sensor is installed in the installation cavity. The temperature sensor is arranged in contact with the top wall of the temperature-sensing conductive head electrode. The top thickness of the temperature-sensing conductive head electrode is 1 mm.

[0052] like Figure 2A As shown, the radio frequency beauty instrument 1 specifically includes: a housing 511 , a first conductive head electrode 201 a / a second conductive head electrode 201 b , a temperature sensing conductive head electrode 301 , a temperature sensor 401 , a spring needle 501 and a conductive head circuit board 505 .

[0053] The end surface of the housing 511 is provided with a light-transmitting lens 512, and a plurality of mounting holes are provided on the light-transmitting lens 512. One end of the first lead electrode 201a / the second lead electrode 201b and the temperature-sensing lead electrode 301 is stuck in the mounting hole, and can be fixedly connected to the light-transmitting lens 512 by physical or chemical means. The other end of the first lead electrode 201a / the second lead electrode 201b and the temperature-sensing lead electrode 301 is fixedly connected to the lead circuit board 505 by the spring pin 501.

[0054] The first conductive head electrode 201a / the second conductive head electrode 201b, the temperature-sensing conductive head electrode 301, and the temperature sensor 401 are all located on the end surface of the housing 511. When the radio frequency beauty device 1 is attached to human skin, the first conductive head electrode 201a / the second conductive head electrode 201b, and the temperature-sensing conductive head electrode 301 are attached to the skin at the same time.

[0055] The conductor circuit board 505 is provided with a cable connection terminal 503. The first conductor electrode 201a / the second conductor electrode 201b, the temperature-sensing conductor electrode 301 and the temperature sensor 401 are connected to the interface terminals corresponding to the cable connection terminals 503. The temperature sensor 401 solders two pins to the two middle soldering pads of the conductor circuit board 505 at a certain height, and the spring pin 501 is also soldered to the soldering pad of the conductor circuit board 505, fixing the temperature-sensing conductor electrode 401 to the light-transmitting lens 512. At this time, the light-transmitting lens 512 is installed on the housing 511, and the light-transmitting lens 512 and the housing 511 can be fixed by physical methods or chemical methods, such as fixing with instant adhesive.

[0056] A capacitor 504 is set between the first conductive head electrode 201a / the second conductive head electrode 201b and the conductive head circuit board 505, and is connected in series with the first conductive head electrode 201a / the second conductive head electrode 201b to achieve voltage division, so as to reduce the total amount of heat generated when all electrodes are not fully attached to the skin, thereby preventing the skin from being scalded by excessive temperature.

The lead electrode group 20 acts on the human skin and performs RF treatment on the human skin to achieve a cosmetic effect. For a better cosmetic effect, the RF output power can be 4MHz, and the gel is not used or used less.

[0058] The temperature sensor 401 is used to detect the temperature of the skin. When the temperature sensing head electrode 301 is attached to the skin, the temperature sensor 401 of the temperature detection device will immediately detect the initial temperature of the skin at this time and transmit it to the central processor. The target temperature in the radio frequency generating module is set in combination with the initial temperature. The radio frequency component controls the power of the radio frequency output in time, thereby achieving real-time detection during radio frequency beauty treatment and controlling the temperature within a safe and effective range, thereby improving the safety and effectiveness of radio frequency beauty equipment.

[0059] Figure 3A to Figure 3C The structural design of the conductor electrode group is exemplarily illustrated. Figure 3A yes Figure 2A Top view of the radio frequency beauty instrument, such as Figure 3AAs shown, the radio frequency beauty device 1 includes a housing 511, and 16 lead electrodes are evenly distributed on the end surface 512 of the housing 511, wherein 201a is a first lead electrode, as shown in the figure, there are 10, 201b is a second lead electrode, as shown in the figure, there are 6, 301 is a temperature-sensing lead electrode and is connected in series with the remaining second lead electrodes, which not only plays the role of the second lead electrode, but also has a temperature detection function, and the first lead electrode 201a and the second lead electrode 201b (including the temperature-sensing lead electrode 301) are arranged alternately to form a lead electrode group 20. The lead electrode group 20 is distributed in an array, with a total of three rows. From top to bottom in the figure, the first row is provided with 5 lead electrodes 201a / 201b, the second row is provided with 6 lead electrodes 201a / 201b, and the third row is provided with 5 lead electrodes 201a / 201b, a total of 16 lead electrodes of the same size and shape. The lead electrode is circular, and its diameter D is not greater than 5mm. The spacing L between adjacent lead electrodes 201 is equal, and the range of L is between 1mm and 4mm. In the center of the second row of lead electrodes, a temperature-sensing lead electrode 301 and a temperature sensor 401 are arranged. In the stamping mode of the radio frequency beauty instrument, the lead electrode group adopts an array distribution mode, which can increase the effective area when working once, and make the lead electrode group act evenly on the human skin. Different from Figure 3A The arrangement of the conductor electrode group, Figure 3B The center position of the electrode is a common guide electrode, which plays the role of the second guide electrode. Figure 3B The arrangement of the conductor electrode group, Figure 3C Among the 16 lead electrodes, only the lead electrode at the center is the first lead electrode 201a, and the remaining 16 lead electrodes are the second lead electrodes 201b.

[0060] Figures 4A to 4E The shapes of the lead electrodes (such as circular, elliptical, quasi-circular, etc.), the number and spacing between adjacent lead electrodes, the shape of the array distribution, and the shape of the end face (quasi-rectangular, circular, quasi-square) are exemplarily illustrated. Those skilled in the art should understand that in order to achieve the same or similar technical effects, adjustments can be made, and all feasible designs are not exhaustive here.

[0061] Compared with the prior art, the technical solution of the embodiment of the utility model has the following beneficial effects:

[0062] First, because the radio frequency beauty device provided by the utility model is safe and reliable, and can detect temperature in real time and control the radio frequency generation module, the radio frequency electrical signal power output by the radio frequency generation module is greater than 4MHz for better beauty effects. When using the radio frequency beauty device of the utility model, there is no need to apply gel on the skin to avoid irritation or allergy to the skin caused by the gel, and it can also prevent the gel from remaining on the guide electrode of the radio frequency beauty device to breed bacteria.

[0063] Thirdly, the human face is three-dimensional rather than planar. When using radio frequency beauty devices for beauty treatments, especially when operating radio frequency beauty devices using non-sliding methods (such as stamping mode), the end faces of some beauty devices are already in close contact with the human facial skin and in full contact, while the end faces of some beauty devices are not in close contact with the human face. Evenly distributing the guide head electrodes and designing the guide head electrodes to be circular or quasi-circular can make it more uniform, especially when performing radio frequency beauty treatments in stamping mode, which can make the heating of the close end faces more uniform, effectively preventing improper operation caused by excessive temperature of some end faces causing burns to the skin, and excessive low temperature of some end faces causing no beauty effect.

[0064] Thirdly, a voltage divider element is added to the RF output circuit board. When the RF loop is formed, the voltage divider element can reduce the total amount of heat generated when all electrodes are not in contact with the skin, thereby preventing the skin from being burned by excessive temperature. At the same time, capacitors are selected as the best, as they do not consume energy, while resistors will generate heat internally.

[0065] Although the utility model is disclosed as above, the utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the scope defined by the claims.
