Description

[0002] With the development of modern society and the continuous improvement of people's living standards, people's demand for beauty products is also becoming increasingly diverse. Beauty devices, as a new type of beauty product, have a broad market prospect. Currently, many beauty devices on the market integrate multiple functions, such as radio frequency, infrared light therapy, and microcurrent functions.

[0003] The aforementioned functions may be used simultaneously. Since each function generates heat when it is activated, and the power supply itself also generates heat during operation, the internal temperature of the beauty device is often quite high. At this time, the vents on the casing alone cannot dissipate the heat to the outside quickly enough, causing the device to overheat after the user holds it for a period of time, affecting the user experience and reducing the device's lifespan in the long run.

[0004] Therefore, we need to improve upon existing technology to provide a portable beauty device that can increase heat dissipation speed. Utility Model Content

The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] refer to Figure 1-9 This utility model provides a portable beauty device that can be used for skin beauty treatments on the face, hands, legs, and other parts of the human body. It includes a housing 1, a heat dissipation device 2, a built-in power supply 3, and a phototherapy mechanism 4, all housed within the housing 1. The heat dissipation device 2 and the phototherapy mechanism 4 are electrically connected to the built-in power supply 3. The built-in power supply 3 is mainly used to supply power to the heat dissipation device 2 and the phototherapy mechanism 4, thereby achieving a portable effect. It does not require a power cord to operate during use. At the same time, the housing 1 is also provided with a charging interface (such as a Type-C interface), which is electrically connected to the built-in power supply 3. When the power of the built-in power supply 3 is insufficient, the user can charge the built-in power supply 3 through the charging interface. The front end of the housing 1 is provided with a light-transmitting plate 10, which refers to the end that comes into contact with the user's skin during use; the phototherapy mechanism 4 is located between the light-transmitting plate 10 and the heat dissipation device 2, and the heat dissipation device 2 is connected to the phototherapy mechanism 4; the built-in power supply 3 is spaced apart on one side of the heat dissipation device 2; the heat dissipation device 2 includes a heat dissipation inlet 201 and a heat dissipation outlet 202; the housing 1 is provided with an air inlet 11 and an air outlet 12; the air inlet 11, the heat dissipation inlet 201, the heat dissipation outlet 202, and the air outlet 12 are connected in sequence to form a heat dissipation channel.

[0033] In this embodiment, the working principle of the portable beauty device is as follows: When in use, the phototherapy mechanism 4 emits light waves outward through the light-transmitting plate 10, and the light waves of a certain wavelength irradiate the human skin to achieve a beauty effect. At the same time as the phototherapy mechanism 4 is turned on, the heat dissipation device 2 also starts to work. Since heat is continuously generated during the power supply process and during the operation of the phototherapy mechanism 4, the temperature inside the shell 1 continues to accumulate. After setting the heat dissipation device 2, the heat generated by the device inside the shell 1 can be guided to the exhaust port 12 through the heat dissipation inlet 201 and the heat dissipation outlet 202, thereby being discharged to the outside, achieving the effect of rapid heat dissipation and cooling, and avoiding affecting the user's user experience.

[0034] This portable beauty device has the following beneficial effects compared to existing beauty devices:

[0035] Traditional beauty devices typically rely solely on the heat dissipation vents of the casing 1 for heat dissipation, resulting in insufficient and inefficient heat dissipation. Furthermore, their use is usually plugged in, which imposes limitations such as the location of the socket and the length of the power cord, causing inconvenience. The beauty device provided by this invention, however, effectively dissipates heat from the casing 1 by incorporating a heat dissipation device 2. This heat dissipation is achieved through a heat dissipation channel formed by the air inlet 11, heat dissipation entrance 201, heat dissipation outlet 202, and exhaust vent 12. Simultaneously, the built-in power supply 3 removes these limitations during use, truly achieving portability and convenience, further enhancing the user experience.

[0036] refer to Figure 5-8 In a preferred embodiment, the heat dissipation device 2 includes a heat dissipation fan 21 and a heat dissipation base 22 connected together. The heat dissipation base 22 serves two purposes: providing a mounting and support position for the heat dissipation fan 21 and guiding the heat dissipation of the entire heat dissipation channel. A heat dissipation inlet 201 and a heat dissipation outlet 202 are respectively located on the heat dissipation fan 21 and the heat dissipation base 22. A mounting base 14 is also provided inside the housing 1. The heat dissipation base 22 is connected to the mounting base 14 to form a heat dissipation cavity 220. The phototherapy mechanism 4 is located within the heat dissipation cavity 220. The heat dissipation inlet 201, the heat dissipation cavity 220, and the heat dissipation outlet 202 are sequentially connected. (Reference) Figure 7 The heat dissipation cavity 220 is designed with one end closed (the closure here refers to a relatively closed state; in actual processes, there may be some gaps, and it is not completely closed) and the other end open (the open end is the heat dissipation outlet 202), thereby ensuring that heat can be efficiently discharged through the open port (i.e., heat dissipation outlet 202), which is beneficial to improving the heat dissipation effect.

[0037] In this embodiment, during heat dissipation, airflow passes through the heat dissipation cavity 220. Therefore, by placing the phototherapy mechanism 4 within this heat dissipation cavity 220, the heat generated during its operation can be dissipated in a timely manner. (Reference) Figure 5 Alternatively, 8. Furthermore, the cooling fan 21 will also have an air outlet 210, which communicates with the heat dissipation cavity 220 of the heat sink 22. As the cooling fan 21 rotates, heat flows through the heat dissipation inlet 201 to the air outlet 210, then enters the heat dissipation cavity 220, and finally is discharged to the outside through the heat dissipation outlet 202 and the exhaust vent 12. For details regarding the airflow direction, please refer to [reference needed]. Figure 6 .

[0038] refer to Figure 5In a preferred embodiment, the heat dissipation outlet 202 is positioned facing the exhaust vent 12. This ensures that heat, upon reaching the heat dissipation outlet 202, can be quickly expelled to the outside through the exhaust vent 12.

[0039] refer to Figure 3-5 In a preferred embodiment, the housing 1 is further provided with a mounting base 14, and a heat dissipation base 22 is connected to the mounting base 14 to form a heat dissipation cavity 220. The phototherapy mechanism 4 is located within the heat dissipation cavity 220. The phototherapy mechanism 4 includes a filter glass 40, a first light source 41, and a reflector 42. The filter glass 40 is positioned close to the light-transmitting plate 10, and the reflector 42 divides the heat dissipation cavity 220 into a first cavity 221 and a second cavity 222 that are connected. At least part of the first light source 41 is located within the second cavity 222. The first cavity 221 and the second cavity 222 are both part of the heat dissipation channel. The working principle of the phototherapy mechanism 4 is as follows: the light emitted by the first light source 41 is reflected by the reflector 42 to the filter glass 40. The filter glass 40 filters light of different wavelengths and finally retains the light of the desired wavelength, which is then irradiated onto the human skin through the light-transmitting plate 10, thereby achieving a better cosmetic effect. Meanwhile, the second cavity 222 serves as part of the heat dissipation channel. The air coming from the cooling fan 21 is split after reaching the heat dissipation cavity 220. Part of the air flows to the first cavity 221 and the other part flows to the second cavity 222. The air flowing through the second cavity 222 can carry away some of the heat generated by the light source, thus achieving the effect of cooling the first light source 41.

[0040] In a preferred embodiment, the phototherapy unit 4 includes a first light source 41 and a filter glass 40. The first light source 41 is a lamp tube, and the emission wavelength of the lamp tube is between 400nm and 2000nm (this refers to the wavelength emitted by the lamp tube before it has been filtered by the filter glass).

[0041] refer to Figure 2-4 In a preferred embodiment, the light-transmitting plate 10 includes a first light-transmitting plate 101 and a second light-transmitting plate 102. The second light-transmitting plate 102 has an opening extending through its thickness. The first light-transmitting plate 101 is placed over the opening, allowing the phototherapy mechanism 4 to emit infrared light through the first light-transmitting plate 101. The wavelength of the infrared light is between 760nm and 1940nm (this refers to the wavelength of the infrared light emitted after filtering by the light-filtering glass). [Reference] Figure 3In a further preferred embodiment, the mounting base 14 has a light-transmitting opening 140 on the side facing the light-transmitting plate 10. The filter glass 40 and the first light-transmitting plate 101 are located on both sides of the light-transmitting opening 140. The light emitted by the first light source 41 of the phototherapy mechanism 4 is filtered by the filter glass 40 and then emitted onto the first light-transmitting plate 101 through the light-transmitting opening 140. In this embodiment, taking milk light as an example (milk light is also called near-infrared light), after passing through the filter glass 40, the light waves of a specific wavelength (near-infrared light) emitted by the first light-transmitting plate 101 penetrate deep into the skin layer. After being absorbed by the water molecules in the skin, they generate a thermal effect, thereby stimulating cell metabolism and collagen production, thus achieving the effect of beautifying and improving skin condition.

[0042] refer to Figure 3 and 4 In a preferred embodiment, the first light-transmitting plate 101 is adapted to the shape and size of the opening. Furthermore, the mounting base 14 has a light-transmitting opening 140 on the side facing the light-transmitting plate 10. The light-transmitting opening 140 corresponds to the opening in position and is also adapted in shape and size, thereby avoiding light leakage.

[0043] refer to Figure 3 and 4 In a preferred embodiment, the housing 1 is further provided with a mounting base 14. A circuit board 15 is provided on the side of the mounting base 14 near the light-transmitting plate 10. The circuit board 15 is located between the mounting base 14 and the light-transmitting plate 10 and is electrically connected to the built-in power supply 3. A second light source 16 is provided on the circuit board 15 and electrically connected thereto. The second light source 16 can emit red light and / or blue light outward through the second light-transmitting plate 102. Red light can penetrate deep into the skin, reaching the dermis, stimulating collagen contraction and regeneration, thereby increasing skin elasticity and firmness. Blue light has a certain bactericidal effect, can regulate sebum secretion, improve the redness and swelling of acne, achieve skin water-oil balance, and accelerate skin metabolism.

[0044] refer to Figure 2-4 In a preferred embodiment, the second light-transmitting plate 102 is further provided with an electrode sheet 17, which is electrically connected to the circuit board 15. During use, because the electrode sheet 17 is in close contact with the skin, the microcurrent emitted by the electrode sheet 17 can stimulate the contraction and relaxation of the skin muscles. Through the stimulation of the EMS microcurrent, the contraction of facial muscles can be promoted, thereby achieving a skin-tightening effect.

[0045] refer to Figure 2 and 4 In a preferred embodiment, there are multiple electrode pads 17, which are arranged around the periphery of the first light-transmitting plate 101. By having multiple electrode pads 17 work simultaneously, a better cosmetic effect can be achieved.

[0046] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
