Detailed Implementation

[0031] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0032] Reference Figure 1 This application illustrates a beauty device provided in an embodiment of the present application, comprising: a housing containing circuit elements and an electrode cover 12 on its side; a cooling plate 14 in the center of the electrode cover 12; and a care electrode 13 surrounding the cooling plate 14 on the electrode cover 12; the circuit elements include a semiconductor cooling chip 24, the cold side of which is attached to the back of the cooling plate 14, and the hot side of which is attached to a heat sink 22.

[0033] In this application, the beauty device uses a semiconductor cooling pad 24 to cool the conductive cooling pad 14. This low-temperature stimulation of the skin effectively constricts blood vessels, reduces inflammation, and alleviates discomfort and redness during the treatment process. This is particularly suitable for sensitive skin, addressing the issue of most beauty devices on the market causing discomfort to nerve endings in the epidermis and even redness in sensitive skin when promoting subcutaneous collagen regeneration due to heating and electrical stimulation. Through the aforementioned treatment electrode 13 and the conductive cooling pad 14, the device achieves both skin tightening by shrinking pores at low temperatures and promoting subcutaneous collagen regeneration through electrode stimulation, providing dual skin care. Compared to traditional single-function beauty devices, this device offers more comprehensive functions and more significant effects. The semiconductor cooling pad 24 is connected to the heat sink 22, which dissipates heat promptly, ensuring the semiconductor cooling pad 24 operates stably and maintaining the low temperature of the conductive cooling pad 14. This ensures the stability and durability of the cooling effect during use, improves ease of use, and enhances the user experience.

[0034] The following will further describe a beauty device according to various exemplary embodiments of this application.

[0035] In an embodiment of this application, a beauty device is provided, wherein the circuit elements include a main PCBA 20 and a negative temperature coefficient thermistor 26; the cooling plate 14 is further provided with a fixing hole, the negative temperature coefficient thermistor 26 is located in the fixing hole, and the negative temperature coefficient thermistor 26 is electrically connected to the main PCBA 20; the negative temperature coefficient thermistor 26 is fixed to the fixing hole by an adhesive.

[0036] As an example, the main PCBA 20 is located inside the instrument and fixed to the heat sink 22 for easy control of the heat dissipation system's operating mode. The aforementioned cooling pad 14 is made of aluminum alloy, a metal with excellent thermal conductivity. The cooling surface of the cooling pad 14 is anodized. Alternatively, the cooling pad 14 can be made of stainless steel, copper, or other materials and electroplated to ensure safety for skin contact. The other side of the cooling surface of the cooling pad 14 is connected to the cold surface of the thermoelectric cooler 24, allowing the thermoelectric cooler 24 to cool the cooling surface of the cooling pad 14. Depending on the instrument mode, the temperature range of the cooling surface is 0–25 degrees Celsius. The heat sink 22 is connected to the hot side of the thermoelectric cooler 24, transferring the heat generated during the operation of the thermoelectric cooler 24 to the heat sink 22. A negative temperature coefficient thermistor 26 is fixed in a mounting hole on the cooling pad 14 using NTC adhesive to detect and monitor the temperature of the cooling surface of the cooling pad 14. This application adds a cooling compress area to the middle area of ​​the beauty device. When the user is caring for their facial skin, the cooling compress will apply a cooling compress to the treated skin as the user slides the device, thereby reducing the user's discomfort caused by electrical stimulation or heat compress and eliminating redness and swelling.

[0037] In the embodiments of this application, the outer shell includes a left shell 10 and a right shell 11; the left shell 10 and the right shell 11 are connected by screws 27 or clips, facilitating the disassembly of the beauty device for internal maintenance. In this application, screws 27 are preferably used to connect the cooling plate 14, electrode cover 12, semiconductor cooling plate 24, and heat sink 22 together. The right shell 11 and the left shell 10 together form the product's outer shape and inner cavity; the outer shape is designed for the user's grip, while the heat sink 22, battery 21, main PCBA 20, etc., are disposed within the inner cavity. The heat sink 22 is fixed inside the left shell 10. The left shell 10 and the right shell 11 together form the product's outer shape and inner cavity; the outer shape is designed for the user's grip, while the heat sink 22, battery 21, main PCBA 20, etc., are disposed within the inner cavity.

[0038] In embodiments of this application, a lamp board 25 and a battery 21 are also included; the lamp board 25 and the battery 21 are electrically connected to the main PCBA 20; the negative temperature coefficient thermistor 26 is electrically connected to the lamp board 25, and the LED beads are electrically connected to the lamp board 25. Specifically, the LED beads are disposed on the lamp board, and a post is provided at the bottom of the nursing electrode for connecting and fixing the nursing electrode 13 to the lamp board 25 through the post and a corresponding screw 27. The LED beads are surface-mount type and are surface-mount soldered onto the lamp board 25, saving space.

[0039] Furthermore, the cold and hot sides of the cooling chip 24 are respectively provided with thermal grease 23 or phase change thermal pads; the battery 21 includes lithium-ion batteries and polymer batteries; the cooling chip 14 and the electrode cover 12 connected thereto are also provided with waterproof adhesive.

[0040] It should be noted that a PCBA is a circuit board on which components are mounted. A PCB is also called a circuit board, printed circuit board, or printed electrical (wire) board, etc. The aforementioned lamp board 25 includes, but is not limited to, a PCBA. The lamp board 25 can also be an FPC or other type of board used to connect and fix electronic components. An NTC (Negative Temperature Coefficient thermistor) is a semiconductor device whose resistance decreases as temperature increases.

[0041] As an example, in electrode cover 12, a cooling pad 14 is positioned in the middle. A waterproof adhesive ring is provided on the contact surface where electrode cover 12 and cooling pad 14 connect to prevent water and cosmetic liquid from penetrating into the product. A negative temperature coefficient thermistor 26 is electrically connected to the lamp board 25 via the aforementioned lamp board 25, providing electrical connection for the thermistor 26 and facilitating temperature acquisition. The aforementioned thermoelectric cooler 24 provides a suitable cooling temperature for the cooling surface of the cooling pad 14 and is electrically connected to the main PCBA 20. Thermal grease 23 is applied to both the cold and hot sides of the thermoelectric cooler 24 to eliminate the gap between the cold side of the thermoelectric cooler 24 and the cooling pad 14; and to the hot side of the thermoelectric cooler 24 to eliminate the gap between the hot side of the thermoelectric cooler 24 and the heat sink 22. The aforementioned battery 21 provides power to the cold compress system. In this application, a lithium battery 18650 battery pack is preferred, but polymer batteries may also be used depending on the internal space of the instrument.

[0042] In this application, a cooling pad is placed in the middle area of ​​the skin care electrode and is mounted on a cooling plate 14. The other side of the cooling pad is connected to the cold side of a thermoelectric cooler 24. Thermal grease 23 is applied between the cooling plate 14 and the thermoelectric cooler 24 to ensure a seamless connection. An NTC fixing hole is provided on the cooling plate 14, in which a negative temperature coefficient thermistor 26 is placed and fixed using NTC adhesive to detect and monitor the temperature of the cooling pad. A heat sink 22 is connected to the hot side of the thermoelectric cooler 24 to conduct heat from the thermoelectric cooler 24. Thermal grease 23 is applied between the thermoelectric cooler 24 and the heat sink 22 to ensure a seamless connection and achieve better heat conduction. Three screw holes are provided on the heat sink 22, through which screws 27 connect to the cooling plate 14, thus connecting the cooling plate 14, the thermoelectric cooler 24, and the heat sink 22 together. The aforementioned thermal grease 23 can also be replaced with a phase change thermal pad, also known as a thermally conductive phase change sheet or phase change plate. When a specified phase change temperature is reached, the phase change material softens, similar to thermal paste, effectively filling interfacial gaps and the voids between electronic components and the heatsink, thus improving heat dissipation. Compared to traditional thermal grease, thermally conductive phase change sheets are much easier to install; there's no need to worry about even application—simply apply them directly. This greatly simplifies the installation process and reduces operational difficulty. Furthermore, phase change thermal pads have a longer lifespan, are less prone to drying or evaporation, and reduce the frequency of maintenance and replacement.

[0043] Furthermore, the nursing electrode 13 includes at least one EMS electrode and / or radio frequency electrode. A phototherapy section is also provided on the electrode cover 12. Specifically, the phototherapy section includes a phototherapy LED light connected to the main PCBA, and the LED light is disposed between the EMS electrode and / or radio frequency electrode within the phototherapy section. Figure 1 As shown, multiple LEDs surround the outer periphery of the cooling plate 14, and EMS electrodes and / or radio frequency electrodes surround the cooling plate 14 at its center. Two or three light-transmitting sections (or light-transmitting holes) can be provided for each EMS electrode and radio frequency electrode, or a material that allows (infrared) therapeutic light to pass through the light-transmitting holes can be provided. Through the aforementioned EMS and radio frequency electrodes, the problems of limited functionality and poor user experience in existing beauty devices are solved. The structural relationship of the functional areas on the electrode cover indicates that, in addition to the cooling function, the surrounding care electrodes can provide muscle stimulation (EMS) and heating (radio frequency) according to the user's selection. By simultaneously heating and stimulating muscles with both types of care electrodes, the therapeutic effect is further enhanced.

[0044] It should be noted that EMS (Electronic Muscle Stimulation) is a device that stimulates muscles with electronic pulses, causing them to contract automatically. It can directly contact the skin and stimulate muscle contraction through low-frequency electrical pulses, thereby simulating brain electrical signals and stimulating brain nerves to complete the movement.

[0045] It should be noted that the temperature status needs to be used in conjunction with a temperature sensor, such as a temperature-sensing resistor. The temperature sensor and application circuit are conventional technologies and will not be described in detail here.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.

[0047] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device.
