Description

Technical Field

[0001] This utility model belongs to the field of radio frequency beauty device technology, specifically relating to a detachable dual-temperature detection radio frequency skin treatment device. Background Technology

[0002] Radiofrequency (RF), microcurrent therapy (EMS), and cryotherapy (COOL) are widely used in the field of beauty devices. The principle is that the device installed on the treatment area of ​​the beauty device emits heat energy, electromagnetic energy, etc., and applies the heat energy and electromagnetic energy to the subcutaneous surface or superficial layer, stimulating elastic fibers and collagen fibers to contract, regenerate and remodel, thereby achieving the effect of eliminating wrinkles and improving skin texture.

[0003] Radiofrequency therapy uses high-frequency radio waves to reach the dermis, causing water molecules in the cells to resonate and rub against each other, generating heat that is transferred to the collagen in the dermis, stimulating collagen to tighten and regenerate.

[0004] Microcurrent therapy uses frequencies from a few Hz to a few kHz to deliver electrical stimulation to the skin, increasing the number of electrons in the skin layers, stimulating cells to repair themselves, improving skin metabolism, and making the skin softer, smoother, and more radiant.

[0005] Cryotherapy uses semiconductor cooling technology. The rapid heat transfer between the cold surface of the semiconductor cooling device and the radio frequency electrode cools the radio frequency electrode. When the radio frequency electrode surface is applied to human skin, it can cool the skin, further shrink pores, lock in moisture, soothe the skin, and relieve redness and swelling.

[0006] However, existing radio frequency beauty devices have limited functions that cannot be combined, resulting in limited treatment objectives, a small number of electrodes, and a small treatment area, leading to insignificant effects. Furthermore, the lack of effective temperature detection and feedback measures increases the risk of burns during use. Additionally, the integrated design of the treatment head and housing makes it inconvenient to disassemble and repair the device when the worktable malfunctions, which requires further improvement. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a detachable dual-temperature detection radiofrequency skin therapy device.

Detailed Implementation

[0027] The present invention will be further described below through specific embodiments.

[0028] Reference Figures 1 to 6 As shown, a detachable dual-temperature detection radiofrequency skin therapy device includes a housing 1, an installation port 2 formed on the upper end of the housing 1, a detachable care head 3 disposed at the installation port 2, a positioning mechanism 4 disposed between the installation port 2 and the care head 3, a switch button 5 disposed on the housing 1 and connected to the care head 3, and three mode selection buttons 6. The three mode selection buttons 6 respectively control the care head 3 to perform RF+COOL+blue light mode, RF+EMS+red light mode, and COOL+blue light mode.

[0029] The nursing head 3 includes a mounting cover 31 disposed at the mounting port 2, a circuit board 32 disposed inside the mounting cover 31, a central electrode 33 disposed on the circuit board 32, a first radio frequency electrode 34 and multiple second radio frequency electrodes 35 disposed around the central electrode 33 on the circuit board 32, a first temperature sensor 36 disposed on the first radio frequency electrode 34, a second temperature sensor 37 disposed on the central electrode 33, a cooling chip 38 connected to the circuit board 32 and disposed on the central electrode 33, a fixing assembly 39 disposed between the circuit board 32 and the mounting cover 31, multiple first LED beads that emit blue light disposed on the circuit board 32, and multiple second LED beads that emit red light disposed on the circuit board 32, wherein the central electrode 33 and the first radio frequency electrode 34... Multiple second radio frequency electrodes 35 extend one end to the surface of the mounting cover 31 and contact the skin; the switch button 5 and three mode selection buttons 6 are respectively connected to the circuit board 32; specifically, a first radio frequency electrode 34 and multiple second radio frequency electrodes 35 are arranged around the central electrode 33, and the polarities of adjacent first radio frequency electrodes 34 and second radio frequency electrodes 35 or two second radio frequency electrodes 35 are opposite; furthermore, the circuit board 32 is provided with a clearance hole 321 for one end of the central electrode 33 to pass through, and the cooling chip 38 is provided at the end of the central electrode 33 that passes through the clearance hole 321; furthermore, 17 second radio frequency electrodes 35 are provided, which, together with one first radio frequency electrode 34 and the central electrode 33, form an equidistant concentric circle arrangement design, which not only increases the treatment area, but also makes the heating effect more uniform.

[0030] The first radio frequency electrode 34 includes a first radio frequency electrode body 341 and a first mounting groove 342 disposed in the first radio frequency electrode body 341 for mounting a first temperature sensor 36. The first temperature sensor 36 detects the temperature of the first radio frequency electrode 34 during operation to prevent the radio frequency electrode from overheating and burning the skin. The first radio frequency electrode 34 and the second radio frequency electrode 35 can be made of metal materials for conducting electricity and heat, generating radio frequency energy, and realizing the treatment and care functions of the beauty device. Specifically, pure copper, silver, copper-tungsten alloy, silver-tungsten alloy, stainless steel, and other metal materials can be used.

[0031] The center electrode 33 includes a center electrode body 331 and a second mounting groove 332 disposed in the center electrode body 331 for mounting a second temperature sensor 37; the second temperature sensor 37 is used to detect the temperature of the cooling chip 38 when it is working, so as to prevent skin from being frostbitten; specifically, both the first temperature sensor 36 and the second temperature sensor 37 are thermistors to accurately detect the temperature of the first radio frequency electrode 34 and the center electrode 33.

[0032] The positioning mechanism 4, disposed between the mounting cover 31 and the mounting opening 2, includes multiple arc-shaped positioning blocks 41 circumferentially distributed on the inner wall of the mounting cover 31, multiple arc-shaped positioning grooves 42 extending inward from the outer circumference of the multiple arc-shaped positioning blocks 41, multiple arc-shaped inserts 43 circumferentially distributed on the inner side of the mounting opening 2 that can be embedded in the corresponding arc-shaped positioning grooves 42, and multiple limiting blocks 44 circumferentially distributed at the mounting opening 2. A rotation area 45 is formed between adjacent arc-shaped inserts 43 for the arc-shaped positioning blocks 41 to rotate. The mounting cover 31 can rotate relative to the mounting opening 2, thereby causing the arc-shaped positioning blocks 41 located in the rotation area 45 to rotate relative to the arc-shaped inserts 43, so that the arc-shaped inserts 43 are embedded in the corresponding arc-shaped positioning grooves 42, thereby achieving a quick connection between the mounting cover 31 and the housing 1. Multiple limiting blocks 44 are respectively disposed on one side of multiple arc-shaped inserts 43 opposite to the rotation direction of the mounting cover 31, limiting the rotation angle of the mounting cover 31, so that the multiple arc-shaped inserts 43 can be respectively fitted into multiple arc-shaped positioning grooves 42; specifically, the upper end of the housing 1 forms a limiting groove 11 extending downward and surrounding the mounting opening 2, and the opposite surface of the mounting cover 31 and the housing 1 forms a limiting ring 311 that can be embedded in the limiting groove 11. Multiple arc-shaped positioning blocks 41 are located inside the limiting ring 311. When the mounting cover 31 is connected to the housing 1, the limiting ring 311 is first embedded into the limiting groove 11, so that the multiple arc-shaped positioning blocks 41 are respectively located in the opposite rotation area 45, and then the mounting cover 31 is rotated to install it into place, realizing the quick connection between the mounting cover 31 and the housing 1.

[0033] In addition, the bottom surface of the front end of the arc-shaped positioning groove 42 is formed with a first guide surface 421 that is inclined upward along the rotation direction of the mounting cover 31, and the bottom surface of the front end of the arc-shaped insert 43 is formed with a second guide surface 431 that is inclined downward along the rotation direction of the mounting cover 31. Through the setting of the first guide surface 421 and the second guide surface 431, the arc-shaped insert 43 is guided to quickly enter the corresponding arc-shaped positioning groove 42. Specifically, four arc-shaped inserts 43 are provided, of which three arc-shaped inserts have the same arc length and are longer than the length of the remaining arc-shaped insert, so as to limit the rotation direction of the mounting cover 31 and ensure the installation. When the cover 31 is connected to the housing 1, the rotation direction is unique. During the rotation of the cover 31, the arc-shaped insert 43 will smoothly enter the relative arc-shaped positioning groove 42 under the action of the first guide surface 421 and the second guide surface 431. Then, under the action of external force, it will continue to enter the arc-shaped positioning groove 42, slightly press the arc-shaped positioning block 41 outward, and under the reaction force, it will be locked in the arc-shaped positioning block 41, thus realizing the connection between the cover 31 and the housing 1. When there is no large external force, the cover 31 will not easily rotate in the opposite direction and detach from the housing 1, ensuring the stability of the nursing head 3 during use.

[0034] The fixing component 39 includes a plurality of fixing posts 391 disposed on the inner side of the mounting cover 31 opposite to the circuit board 32, a plurality of first fixing holes 392 disposed in the plurality of fixing posts 391, a plurality of second fixing holes 393 disposed on the circuit board 32 opposite to the plurality of first fixing holes 392, and a plurality of fixing bolts threaded through the second fixing holes 393 and threadedly connected to the first fixing holes 392. The circuit board 32 is fixed to the inner side of the mounting cover 31 by the fixing bolts engaging with the first fixing holes 392.

[0035] During use, press the corresponding mode selection button 6 according to the needs of use, so that the circuit board 32 controls the treatment head 3 to work in the corresponding mode. When the RF+COOL+blue light mode is selected, RF can act on the dermis of the skin, while COOL+blue light can soothe the skin surface, thus ensuring that the therapeutic effect of RF is effective in the dermis, and COOL+blue light ensures that the skin surface is not burned. When the RF+EMS+red light mode is selected, when RF heats the dermis of the skin, EMS+red light can stimulate cells to repair themselves, doubling the effect. When the COOL+blue light mode is selected, COOL can soothe the skin and relieve redness and swelling, while blue light can reduce inflammation and promote healing. The combination of the two can quickly reduce swelling and relieve skin redness and swelling.

[0036] This application, by limiting the structural composition of the care head 3, enables the radio frequency beauty device to be used in RF+COOL+blue light mode, RF+EMS+red light mode, and COOL+blue light mode. Each mode is combined with multiple functions for more significant results. In addition, the care head 3 is detachably mounted on the housing 1 through the positioning mechanism 4, making the assembly of the care head 3 simpler, easier to disassemble and assemble, and convenient for maintenance.

[0037] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model application and the contents of the specification should still fall within the scope of the present utility model application.
