Description

Technical fields:

[0001] This utility model relates to the field of beauty instrument technology, and in particular to a cryo-radio frequency microcrystalline beauty instrument. Background technology:

[0002] Most current beauty devices use radio frequency (RF) technology. When RF energy based on a specific waveform is applied to the skin, it can improve the skin's shape. By applying RF output electrodes to the skin, conduction and displacement currents flow through the skin, creating internal heating. This promotes collagen synthesis and regeneration, causes collagen fibers to contract and tighten, and increases the thickness and density of the dermis, resulting in lifted and firmer skin, enhanced skin elasticity, and improved absorption of nutrients.

[0003] When using a radio frequency (RF) beauty device, under the control of an electronic system, dozens of insulated needles simultaneously and rapidly penetrate the epidermis, emitting RF energy from the needle tips before quickly withdrawing from the skin. By delivering RF energy deep into the skin through tiny needles, micro-damage is created, penetrating and opening the skin's absorption channels, facilitating the entry of nutrient products and triggering the body's natural healing response. At this time, combined with the thermal stimulation generated by the RF, the skin may experience noticeable pain. Utility model content:

[0004] The purpose of this invention is to provide a cryo-radiofrequency microcrystalline beauty device, which incorporates a cryo-temperature control module. The cryo-temperature control module controls the skin surface temperature at 5-10℃ through pre-cooling and real-time temperature adjustment. Combined with the deep action of radiofrequency microneedles, it can reduce the pain of using the beauty device, improve user comfort, and also enhance the treatment effect.

[0005] This utility model is implemented by the following technical solution: a cryo-radiofrequency microcrystalline beauty device, including a main control module, a cryo-temperature control module, a radiofrequency microcrystalline module, a human-computer interaction module and a power supply module, wherein the main control module is connected to the cryo-temperature control module, the radiofrequency microcrystalline module and the human-computer interaction module respectively;

[0006] The power supply module supplies power to the main control module, cryo-temperature control module, radio frequency microcrystal module, and human-machine interaction module via an output line. The radio frequency microcrystal module includes a microcrystal component, a working head circuit board, and a motor assembled sequentially. The microcrystal component is used to penetrate the skin. The working head circuit board integrates a radio frequency energy emission unit to transmit radio frequency energy to subcutaneous tissue. The motor drives the microcrystal component to achieve needle depth adjustment. The cryo-temperature control module includes a cooling copper plate, a cryo-temperature control component, and a handle head circuit board. The cooling copper plate is attached to the inside of the working head shell to cool the skin surface. The handle head circuit board integrates a temperature adjustment unit, which, in conjunction with a temperature sensor, collects skin temperature in real time and adjusts the operation of the cooling copper plate. The human-machine interaction module includes a button circuit board, buttons, and a side light bar. The button circuit board integrates buttons for inputting treatment parameters and controlling the device's start and stop. The side light bar indicates the device's operating status.

[0007] Furthermore, the cooling copper sheet is made of copper, and thermally conductive silicone is applied to the surface of the sheet that contacts the working head housing to achieve a tight fit.

[0008] Furthermore, a positioning post is pre-set on the inner side of the working head housing, and a positioning hole is opened on the working head circuit board accordingly. The positioning post is inserted into the positioning hole to achieve preliminary positioning. The output shaft of the motor is connected to the transmission end of the microcrystalline component through a coupling or gear meshing. The motor housing is fixed to the working head circuit board by screws. A pressure plate seat covers the joint between the microcrystalline component and the working head circuit board.

[0009] Furthermore, the handle head circuit board is connected to the positioning post of the working head shell by screws, the temperature adjustment unit is connected to the cooling copper sheet by wires, and the temperature sensor is fixed to the working head shell near the skin contact position by clips or adhesive, and is electrically connected to the handle head circuit board; the freezing temperature control component is fixed to the reserved space inside the working head shell by screws, and is in contact with the non-contact surface of the cooling copper sheet.

[0010] Furthermore, it also includes a handle shell, which is assembled from a working head shell, an upper handle shell, a left handle shell, and a right handle shell. Adjacent shell edges are respectively provided with buckle protrusions and buckle grooves. Initial positioning is achieved by the engagement of the buckle protrusions and buckle grooves. Adjacent shells are pre-drilled with screw holes, through which screws pass to fix the shells. The handle formed by the left and right handle shells is fitted with a silicone handle sleeve. The surface of the silicone handle sleeve is pressed with anti-slip texture and is interference-fitted with the handle shell.

[0011] Furthermore, the left and right outer shells of the handle have pre-set slots inside, and a wire clamping seat is fixed in the slot. The wire clamping seat is fixed to the inner wall of the outer shell by a buckle or screw. The center of the wire clamping seat has a through hole that matches the output wire. The output wire passes through the through hole and is clamped by the wire clamping seat. The output wire is a multi-core shielded wire with an outer insulating protective sleeve.

[0012] Furthermore, the microcrystalline component housing has a buckle on its edge, and the working head housing has a corresponding buckle groove on its inner side. The microcrystalline component is detachably connected to the working head housing by the engagement of the buckle and the buckle groove. The microcrystalline component is compatible with probes of 12P, 24P, 40P and nanocrystalline head specifications.

[0013] Furthermore, the buttons of the human-computer interaction module are fixed to the button circuit board by welding. The outer shell of the handle has a groove adapted to the button circuit board.

The side light strip circuit board is fixed to the inside of the handle shell by screws and is electrically connected to the main control module by wires.

[0015] Advantages of this utility model:

[0016] 1. Significantly reduces pain: By controlling the skin surface temperature at 5-10℃ through the cryo-temperature control module, combined with the deep action of radiofrequency microneedles, clinical tests show that the pain score (VAS scale) has dropped from 6-7 points in traditional devices to 2-3 points, greatly improving user comfort.

[0017] 2.

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0020] Figure 1 This is a block diagram illustrating the control system principle of a cryo-radiofrequency microcrystalline beauty device according to an embodiment of the present invention.

[0021] Figure 2 This is an exploded structural diagram of a cryo-radiofrequency microcrystalline beauty device according to an embodiment of the present invention. Detailed implementation method:

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 As shown, this utility model proposes a cryo-radiofrequency microcrystalline beauty device, including a main control module 1, a cryo-temperature control module 2, a radiofrequency microcrystalline module 3, a human-computer interaction module 4, and a power supply module 5. The main control module 1 is connected to the cryo-temperature control module 2, the radiofrequency microcrystalline module 3, and the human-computer interaction module 4 respectively.

[0024] The main control module 1 uses a high-performance microprocessor to coordinate and control the operation of the radiofrequency microcrystal module and the cryotherapy temperature control module. It can precisely control the timing and intensity of the two modules based on set treatment parameters, such as needle depth, radiofrequency energy intensity, and cryotherapy temperature, ensuring the stability and safety of the treatment process.

[0025] The cryo-temperature control module 2 includes a cooling copper plate 10, a cryo-temperature control component 11, and a handle head circuit board 12. The cooling copper plate 10 is attached to the inside of the working head shell 13 to cool the skin surface. The handle head circuit board 12 integrates a temperature regulation unit 201, which, together with a temperature sensor 202, collects skin temperature in real time and regulates the operation of the cooling copper plate 10. The cooling copper plate 10, as a cooling unit, uses semiconductor cooling technology to achieve rapid cooling. The temperature sensor monitors the skin surface temperature in real time and feeds the data back to the temperature regulation unit. The temperature regulation unit adjusts the cooling unit according to the feedback data to stabilize the skin surface temperature at 5-10℃. The function of this module is to reduce the skin surface temperature and alleviate pain during radiofrequency microdermabrasion treatment through pre-cooling and real-time temperature regulation.

[0026] The radiofrequency microcrystal module 3 comprises, sequentially assembled, microcrystal components 7, a working head circuit board 8, and a motor 9. Microcrystal components 7 penetrate the skin, the working head circuit board 8 integrates a radiofrequency energy emission unit to deliver radiofrequency energy to the subcutaneous tissue, and the motor 9 drives the microcrystal components 7 to adjust the needle depth. The microcrystal components 7 employ an array-type microcrystal needle, with a body diameter of 0.22mm, gradually tapering towards the tip to 0.1mm. This minimizes damage to the epidermis, preventing burns and pigmentation, while facilitating precise delivery of radiofrequency energy from the needle tip to the subcutaneous tissue. Its function is to penetrate the skin, open absorption channels, and deliver radiofrequency energy deep into the skin to create micro-damage, triggering the body's natural healing response and promoting collagen synthesis.

[0027] The human-machine interface module 4 includes a button circuit board 14, buttons 15, and a side light strip 16. The button circuit board 14 integrates buttons 15 for inputting treatment parameters and controlling the start and stop of the device. The side light strip 16 is used to indicate the device's operating status. The human-machine interface module 4 includes a display screen and operation buttons. The display screen is used to display information such as treatment parameters and device operating status; the operation buttons allow users to set treatment parameters, such as adjusting the needle depth between 0.5 and 7 mm.

[0028] Among them, the power supply module 5 supplies power to the main control module 1, the refrigeration temperature control module 2, the radio frequency microcrystal module 3, and the human-machine interaction module 4 through the output line 6.

[0029] I. External Shell Structure Design

[0030] The handle housing is the basic load-bearing structure of the equipment, consisting of four parts: the working head housing 13, the upper handle housing 20, the left handle housing 21, and the right handle housing 22. The housings are secured using a dual "buckle + screw" method: pre-set buckle grooves and buckle protrusions on the edges of adjacent housings allow for initial positioning via the buckles, followed by screwing in pre-set screw holes for rigid fixation. At the grip area formed by the left and right handle housings 21 and 22, a silicone handle sleeve 23 is interference-fitted. The inner wall of the silicone sleeve fits tightly against the surface of the housing, and the surface of the silicone sleeve is pressed with anti-slip textures. The snap-fit ​​connection enables quick pre-assembly, while the screw fixation ensures the structural stability of the assembled housings, preventing loosening due to vibration during equipment operation. The interference fit of the silicone sleeve at the grip prevents displacement during use and enhances grip comfort through the flexibility of silicone. The anti-slip textures increase friction between the hand and the grip, preventing the equipment from slipping in wet or slippery environments (such as when in contact with skincare products).

[0031] Meanwhile, the left outer shell 21 and right outer shell 22 of the handle have pre-set slots for fixing the wire clamping base 24. The wire clamping base 24 is connected to the inner wall of the outer shell by a buckle or screw, and has a through hole in its center that matches the output wire 6. After the output wire 6 (multi-core shielded wire with an outer insulating protective sleeve) passes through the through hole, it is clamped and fixed by the wire clamping base 24. This design can prevent the output wire from becoming loose from the internal module's connection terminal due to pulling during equipment movement or use, ensuring the stability of power supply and signal transmission. The outer insulating protective sleeve prevents the risk of leakage caused by wire wear.

[0032] II. Stack-up Assembly and Transmission Connection of RF Microcrystal Modules

[0033] The radiofrequency microcrystal module, as the core treatment component, is assembled by stacking the microcrystal assembly 7, the working head circuit board 8, and the motor 9 in sequence, and is rigidly fixed to the working head shell 13 by the pressure plate seat 17.

[0034] The inner side of the working head housing 13 has a pre-set positioning post, and the working head circuit board 8 has a corresponding positioning hole. The circuit board is fitted into the positioning post through the positioning hole to achieve initial positioning. The output shaft of the motor 9 is connected to the transmission end of the microcrystalline component 7 through a coupling or gear meshing. The motor housing is fixed to the working head circuit board 8 by screws. The outer edge of the microcrystalline component 7 is provided with a buckle, which forms a buckle connection with the buckle groove on the inner side of the working head housing 13. At the same time, the pressure plate seat 17 covers the joint between the microcrystalline component 7 and the working head circuit board 8. The three are pressed and fixed by screws passing through the pressure plate seat 17, the working head circuit board 8 and the positioning post of the working head housing 13.

[0035] The stacked assembly makes the radiofrequency microcrystal module more compact, reducing the overall size of the device. The fit between the positioning post and the positioning hole ensures that the central axes of the working head circuit board 8, motor 9, and microcrystal assembly 7 are aligned, preventing needle wobbling caused by eccentricity during motor drive and ensuring the accuracy of skin penetration by the microcrystal assembly 7. The snap-fit ​​connection facilitates quick replacement of the microcrystal assembly 7 (compatible with different specifications of probes such as 12P, 24P, 40P, and nanocrystalline tips) to meet different treatment needs, while the clamping action of the pressure plate seat 17 further enhances the stability of the module assembly and prevents component displacement under high-frequency vibration from affecting the treatment effect. The transmission connection between the motor 9 and the microcrystal assembly 7 allows the forward and reverse rotation of the motor to drive the extension and retraction of the needle of the microcrystal assembly 7, achieving a depth adjustment of 0.5-7mm to adapt to skin tissues of different thicknesses.

[0036] III. Fitting and fixing the freezing temperature control module to the working head housing

[0037] The cooling copper sheet 10 in the freezing temperature control module is bonded to the working head housing 13 with thermally conductive silicone, while the handle head circuit board 12 and the freezing temperature control component 11 are fixed to the inside of the working head housing 13 with screws.

[0038] One side of the cooling copper sheet 10 (made of copper, optional semiconductor cooling sheet or compression cooling end) is coated with thermally conductive silicone and tightly adhered to the preset plane on the inner side of the working head housing 13. After the silicone cures, a stable bonding structure is formed. The handle head circuit board 12 is connected to the positioning post of the working head housing 13 by screws. Its integrated temperature regulation unit 201 is connected to the cooling copper sheet 10 by wires. The temperature sensor 202 is fixed to the working head housing 13 near the skin contact position by clips or adhesives and is electrically connected to the handle head circuit board 12. The freezing temperature control component 11, including heat sink, fan, etc., is fixed to the reserved space on the inner side of the working head housing 13 by screws and is in contact with the non-adhesive surface of the cooling copper sheet 10.

[0039] The copper cooling plate, made of purple copper, has excellent thermal conductivity. Thermally conductive silicone can fill the tiny gap between the copper cooling plate and the working head shell, reducing thermal resistance and ensuring that the cooling energy of the copper cooling plate can be efficiently transferred to the working head shell 13, thereby cooling the skin surface. The temperature sensor 202 is close to the skin contact position and can accurately collect the skin temperature in real time, feeding it back to the temperature regulation unit 201 to achieve precise temperature control of 5-10℃, reducing treatment pain. The contact between the freezing temperature control component 11 and the copper cooling plate can promptly remove the heat generated by the copper cooling plate, preventing it from reducing cooling efficiency due to overheating and ensuring the continuous and stable operation of the temperature control module.

[0040] IV. Integration and Connection of Human-Computer Interaction Module

[0041] The human-computer interaction module consists of a button circuit board 14, buttons 15, a side light strip board 16, and a side light strip board circuit board 18. Each component forms a dual connection with the handle housing and the main control module, both mechanically and electrically.

[0042] Button 15 is fixed to button circuit board 14 by soldering. Button circuit board 14 is fixed to the preset groove in the upper shell 20 of the handle by screws or clips. The opening of the groove matches the position of button 15 to ensure that the user can press it normally. Side light strip plate 16 is fixed to the inner light groove of the left shell 21 or right shell 22 of the handle by double-sided tape or clips. The pins of the light strip plate are soldered to the side light strip plate circuit board 18 by wires. The side light strip plate circuit board 18 is fixed to the inside of the handle shell by screws and is electrically connected to the main control module 1 by wires. Button circuit board 14 also communicates with the main control module 1 by wires. Button 15 includes parameter confirmation key, ± adjustment key, mode switching key and emergency stop key.

[0043] The soldering and fixing of button 15 and button circuit board 14 ensures stable transmission of operation signals. The circuit board is fixed in the groove of the outer shell of the handle to prevent the button from shifting due to external force. The side light strip plate 16 is embedded in the light groove, which can protect the light strip from collision damage and allow the light to clearly display the equipment status (such as red when pre-cooling, green when the temperature reaches the standard, and red flashing when there is a fault) through the light-transmitting area of ​​the outer shell. The wires connecting each circuit board to the main control module realize the transmission of user operation commands (such as parameter adjustment, equipment start and stop) and the feedback of equipment status signals, ensuring the smoothness of human-machine interaction.

[0044] In summary, this utility model integrates four major modules—main control module, cryogenic temperature control module, radiofrequency microcrystal module, and human-computer interaction module—into the handle shell. This not only ensures the structural stability and functional accuracy of the device during operation but also provides convenience for subsequent component replacement, cleaning, and maintenance, ultimately achieving the core function of "low-temperature pain relief + precise radiofrequency therapy."

[0045] The working principle of this utility model is as follows:

[0046] After the device is started, the user sets the treatment parameters through the human-machine interface module. Upon receiving the parameters, the main control module first controls the cryo-temperature control module to pre-cool the skin surface. When the temperature reaches 5-10℃, the radiofrequency microcrystal module's needle penetrates the skin, simultaneously emitting radiofrequency energy. During treatment, the temperature sensor monitors the skin surface temperature in real time. If the temperature deviates from the set range, the main control module will promptly adjust the cryo-temperature control module to ensure comfort and safety during the treatment. The device automatically stops operating after treatment.

[0047] This utility model achieves the following technical effects:

[0048] 1. Significantly reduces pain: By controlling the skin surface temperature at 5-10℃ through the cryo-temperature control module, combined with the deep action of radiofrequency microneedles, clinical tests show that the pain score (VAS scale) has dropped from 6-7 points in traditional devices to 2-3 points, greatly improving user comfort.

[0049] 2. Improved treatment efficacy: Cryotherapy can reduce pain and minimize skin damage caused by high temperatures, allowing the skin to better cope with the stimulation from radiofrequency microneedling and promoting repair processes such as collagen synthesis, thereby improving treatment efficacy.

[0050] 3. Compatible with multiple probe sizes (12P, 24P, 40P, nano-crystal tip), ensuring safer single-use. Capable of radiofrequency fractional treatment up to 7mm deep, with needle depth adjustable between 0.5 and 7mm, suitable for skin of any thickness.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
