Description

Technical Field

[0001] This utility model relates to the field of beauty equipment technology, and in particular to a heated beauty device. Background Technology

[0002] Existing beauty devices generally use heating films to directly conduct heat. Their working principle involves generating heat through heating elements, which is then directly or indirectly transferred to the jade surface of the device to achieve a heat therapy function. However, this traditional technology has significant limitations in terms of energy efficiency and temperature stability, specifically manifested in the following defects: 1. Excessive thermal resistance at the conduction interface: There is a gap in the conduction structure between the heating element and the jade working surface, which causes interface loss during heat transfer, reducing the proportion of effective heat actually reaching the jade working surface.

[0003] 2. Lack of systematic heat preservation: The beauty device lacks a targeted heat preservation design. Heat is easily lost quickly through the heat conduction of the outer shell material and the air convection through the gaps between the components, resulting in non-working heat loss.

[0004] 3. Design flaws in conductive components: The heat dissipation area of ​​conductive components has not been optimized. Excessively exposed surfaces accelerate the diffusion of heat to non-target areas, further aggravating energy loss. Utility Model Content

[0022] like Figure 1-4The illustrated heating beauty device includes a main body 1 and a massage head 2. The massage head 2 includes a head shell 3, a support 4, a PCB board 5, a heat-conducting component 6, a flexible heat-conducting sheet 7, and a jade stone 8. The head shell 3 is connected to the main body 1. The support 4 is disposed inside the head shell 3. The PCB board 5 is disposed on the support 4 and has a heating resistor 51. The heat-conducting component 6 is disposed on the PCB board 5, and its lower surface is attached to the upper surface of the PCB board 5. The flexible heat-conducting sheet 7 is disposed on the inner side of the jade stone 8, and its upper surface is attached to the jade stone 8, while its lower surface is attached to the heat-conducting component 6. The jade stone 8 is disposed at the top of the head shell 3. It should be noted that the main body 1 of the beauty device is the user's handheld part, which also contains components such as a motherboard and a battery. The massage head 2 is the part used by the user for massage. The jade stone 8 at the top of the massage head 2 is used to contact the user's skin. The heat generated by the heating resistor 51 is transferred to the jade stone 8 to achieve the function of heat therapy.

[0023] Specifically, the head shell 3 can be made of ABS engineering plastic (acrylonitrile-butadiene-styrene copolymer), which has both lightweight and insulating properties. Furthermore, the PCB board 5, the heat-conducting component 6, and the flexible heat-conducting sheet 7 all have gaps with the head shell 3 to utilize the low thermal conductivity of air to prevent heat leakage. The bracket 4 can be fixedly connected to the head shell 3 with bolts. Multiple heating resistors 51 are spaced apart on the PCB board 5 to improve heating efficiency. The jade stone 8 is a translucent material, and Tianyu jade or Xiuyan jade can be used as the base material. The thickness is designed to be 3-5mm to take into account both the warm touch and heat storage properties.

[0024] The beneficial effects of this utility model are as follows: the heating resistor 51 on the PCB board 5 can generate heat and conduct the heat to the heat-conducting component 6, then to the flexible heat-conducting sheet 7, and finally to the jade stone 8; the heat-conducting component 6 can improve the heat conduction efficiency, and the deformation characteristics of the flexible heat-conducting sheet 7 can reduce the interface thermal resistance to improve the heat conduction efficiency, and can make the heat evenly conduct to the jade stone 8, which greatly improves the user experience.

[0025] Please refer to Figure 4In one possible implementation, the flexible heat-conducting sheet 7 is made of a light-transmitting material, the PCB board 5 is provided with LED beads 52, and the heat-conducting component 6 is provided with a first hole 61, with the LED beads 52 placed inside the first hole 61. It should be noted that there are multiple LED beads 52 and multiple first holes 61, with each LED bead 52 corresponding to each first hole 61. The first hole 61 can avoid the LED beads 52, which can both ensure that the PCB board 5 and the heat-conducting component 6 fit tightly together, and allow the light emitted by the LED beads 52 to pass smoothly through the flexible heat-conducting sheet 7 and the jade stone 8. The LED beads 52 can emit red and blue light to achieve a phototherapy effect. In addition, the light emitted by the LED beads 52 can also illuminate the jade stone 8, thereby improving the aesthetics of the jade stone 8 and enhancing the user experience. Furthermore, the LED beads 52 can also generate heat when working, and the continuous irradiation of the jade stone 8 by the LED beads 52 can improve the temperature stability of the jade stone 8.

[0026] Please refer to Figure 4 In one possible implementation, a vibration motor 9 is also included. The vibration motor 9 is mounted on the bracket 4 and can drive the bracket 4 to vibrate. It should be noted that the vibration motor 9 can generate inertial vibration by rotating the eccentric wheel at the shaft end, and achieve the mechanical vibration effect by utilizing the uneven mass distribution. The vibration motor 9 can drive the bracket 4 to vibrate, thereby causing the head shell 3 to vibrate, and thus causing the entire massage head 2 to vibrate, so as to realize the massage function. Furthermore, the bracket 4 is provided with a mounting groove 42, and the vibration motor 9 is disposed in the mounting groove 42 to improve the stability of the vibration motor 9.

[0027] Please refer to Figure 4 In one possible implementation, the heat-conducting component 6 is provided with a second hole 62, and the PCB board 5 is provided with a touch spring 53. The touch spring 53 is placed in the second hole 62, the lower end of the touch spring 53 is electrically connected to the PCB board 5, and the upper end of the touch spring 53 abuts against the flexible heat-conducting sheet 7. It should be noted that the touch spring 53 is located at the center of the PCB board 5, and correspondingly, the second hole 62 is also located at the center of the heat-conducting component 6. The second hole 62 can avoid the touch spring 53 so that the touch spring 53 can contact the flexible heat-conducting sheet 7. The touch spring 53 (also known as a touch sensing spring or button spring) is a spring button specifically used in capacitive and single-chip microcomputer touch screen electrical appliances. It is made of materials such as piano carbon steel wire and stainless steel wire, and the surface plating includes environmentally friendly nickel and gold plating processes. When the user's skin touches the middle area of ​​the jade stone 8, the touch spring 53 is triggered, thereby causing the touch spring 53 to emit an electrical signal to the PCB board 5, which in turn causes the beauty device to start working automatically. The flexible heat-conducting sheet 7 also has a conductive function, which helps to increase the touch area of ​​the touch spring 53.

[0028] Please refer to Figure 2In one possible implementation, a touch ring 10 is also included. The upper end of the touch ring 10 is connected to the lower end of the jade stone 8, and the touch ring 10 is electrically connected to the PCB board 5. It should be noted that the upper end of the touch ring 10 is bonded to the lower end of the jade stone 8. The touch ring 10 is made of a conductive metal material, preferably aluminum. The touch ring 10 is connected to the PCB board 5 via a wire. When the user's skin touches the edge area of ​​the jade stone 8, the touch ring 10 is triggered, causing it to emit an electrical signal to the PCB board 5, thereby automatically starting the beauty device. It is easy to understand that both the touch spring 53 and the touch ring 10 act as trigger signals and work simultaneously. When either the touch spring 53 or the touch ring 10 is triggered, the beauty device can start working, greatly improving the sensitivity of the beauty device.

[0029] Please refer to Figures 2 to 4 In one possible implementation, a sealing groove 31 is provided on the inner wall of the head shell 3, and a sealing ring 32 is provided in the sealing groove 31. The sealing ring 32 abuts against the bracket 4. It should be noted that the sealing groove 31 provides a mounting base for the sealing ring 32 and also limits its position. The bracket 4 is installed inside the head shell 3, and there is a gap between the bracket 4 and the head shell 3. The sealing ring 32 is used to seal this gap, thereby improving the waterproof performance of the massage head 2. Furthermore, the sealing ring 32 is made of a high-temperature resistant material to prevent the sealing ring 32 from melting.

[0030] Please refer to Figure 2 In one possible implementation, the sidewalls of the heat-conducting component 6 are covered with aerogel felt. It should be noted that aerogel felt is a thermal insulation material composed of nanoporous aerogel and inorganic fiber materials, possessing excellent thermal insulation properties. By covering the sidewalls of the heat-conducting component 6 with aerogel felt, the heat dissipation rate of the heat-conducting component 6 to the surrounding environment is greatly reduced, thereby improving the thermal insulation performance of the heat-conducting component 6. This reduces heat loss and also avoids discomfort caused by excessive temperature fluctuations in the jade stone 8, leading to either excessive cold or excessive heat, thus improving the user experience.

[0031] Please refer to Figure 4 In one possible implementation, the bracket 4 is provided with a support column 41, and the PCB board 5 is disposed on the support column 41. It should be noted that the PCB board 5 can be fixed to the support column 41 by bolts. The support column 41 not only serves to fix the PCB board 5, but also reduces the contact area between the PCB board 5 and the bracket 4, thereby reducing the heat conducted from the PCB board 5 to the bracket 4, thus reducing the heat loss of the PCB board 5. Furthermore, the support column 41 can also be made of heat-insulating material to further reduce heat loss.

[0032] Please refer to Figure 3In one possible implementation, the flexible heat-conducting sheet 7 is either a thermally conductive double-sided adhesive or a hydrogel. It should be noted that the thermally conductive double-sided adhesive is an industrial bonding material made of acrylic polymer composite thermally conductive ceramic powder and silicone adhesive; the hydrogel is a type of highly hydrophilic three-dimensional network structure gel that rapidly swells in water and can retain a large volume of water without dissolving in this swollen state; both the thermally conductive double-sided adhesive and the hydrogel have excellent thermal conductivity, electrical conductivity, and light transmittance properties, which can improve the thermal conductivity between the heat-conducting component 6 and the jade stone 8, enhance the touch spring 53, facilitate the export of light from the phototherapy lamp, and improve various performance characteristics of the beauty device.

[0033] In one possible implementation, the thermal conductive element 6 may be thermally conductive silicone grease. It should be noted that the thermally conductive component 6 is preferably thermally conductive silicone grease, which is a high thermal conductivity and insulating silicone material. Thermally conductive silicone grease is a thermally conductive silicone grease-like compound made primarily of silicone, with added heat-resistant and thermally conductive materials. It features high thermal conductivity, excellent thermal conductivity, good electrical insulation, a wide operating temperature range, good stability, low consistency, and good workability. Alternatively, the thermally conductive component 6 can also be made of metals such as silver, copper, or aluminum. Metal thermally conductive components 6 have a higher heating rate than thermally conductive silicone grease, but metal assembly requires higher precision, mainly in terms of component fit tolerances. If the dimensional accuracy of other components is not well controlled, it can easily cause them to not fit perfectly with the metal, leading to a decrease in heat transfer efficiency. The softness of thermally conductive silicone grease can overcome this defect. Furthermore, the thermal conductivity of thermally conductive silicone grease is higher than that of rubber and silicone. Therefore, the material of the thermally conductive component 6 can be changed according to the user's actual needs; either thermally conductive silicone grease or metal can be used to meet diverse user requirements.

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
