Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

First preferred embodiment:

The housing 101 has a cavity for receiving at least a portion of the components to which the phototherapy assembly 300 is mounted. In the present embodiment, according to the reference direction of fig. 1, the cavity of the housing 101 has an upward and downward opening, the lens 103 closes one side of the housing 101, the rear cover 102 closes the other side of the housing 101, and the lens 103 may be an integral part of the housing 101 as an alternative embodiment.

The phototherapy unit 300 is provided in the housing 101, and the phototherapy unit 300 includes a circuit board 301 having a plate-like structure and a heat dissipation plate 302. The phototherapy unit 300 is located on one side of the lens 103, and the heat dissipation plate 302 is located on one side of the rear cover 102. At least a portion of the heat dissipation plate 302 abuts against the surface of the circuit board 301, and the heat dissipation plate 302 is connected to the surface of the circuit board 301 through heat-conductive silicone grease. The heat sink 302 is typically a metallic material, such as aluminum, copper, and aluminum alloy, with good thermal conductivity. These materials can rapidly absorb heat generated by the light source of the phototherapy assembly 300, and rapidly emit the heat in a surface heat-dissipating manner, thereby maintaining the normal operation of the light source of the phototherapy assembly 300. As an alternative embodiment, the heat dissipation plate 302 may also be made of ceramic or glass.

The phototherapy assembly 300 has a light source that generally employs light of a specific wavelength, such as blue light, red light, yellow light, etc., which may directly or indirectly produce different cosmetic effects on the skin, such as skin lightening, skin effect improvement, skin chromaticity lightening, pore refinement, etc. Such as: the blue light has the effects of sterilizing, diminishing inflammation, reducing grease secretion and the like, can relieve the problems of acne and the like, and has certain improvement effects on the problems of acne marks, color spots, dark yellow skin and the like; the red light has effects of promoting collagen production, increasing skin elasticity, etc., and can improve wrinkle, relaxation, etc. In this embodiment, the blue wavelength is selected to be between 400 and 500 nanometers, the red wavelength is selected to be between 600 and 700 nanometers, and the yellow wavelength is generally selected to be between 570 and 600 nanometers. Light of these wavelengths is believed to be beneficial to the skin. Notably, the specific wavelength depends on different cosmetic functions and therapeutic purposes. For example, the wavelength of blue light is 400-470nm, and the blue light with certain curative effects on treating acne, inflammation, allergy and the like can destroy the DNA structure of bacteria and cause the bacteria to die, so that the occurrence of the acne and the inflammation is reduced. The wavelength of the red light is between 630 and 700nm, and the red light has certain curative effects on the aspects of promoting metabolism of skin cells, increasing skin elasticity and compactness, improving skin pigmentation, blood circulation and the like, and can lighten skin color. The red light may stimulate collagen production, thereby reducing wrinkles and sagging phenomena. Huang Guangneng has effects in promoting blood circulation, removing lymph toxin, increasing toughness of capillary vessel, improving skin immunity, reducing skin sensitivity, resolving pigment, removing mottle, and refining pores.

In general, the power and the radiation angle of the light source affect the radiation range of the light, and when the power is smaller, the radiation range is smaller, so that the face of the human body needs to be close to the face. The use is inconvenient. Therefore, it is necessary to boost the power of the light source in the phototherapy assembly 300. The relatively generated heat after lifting is more transferred to the circuit board 301 and the housing.

Therefore, a heat dissipation structure is further disposed in the frame 101, the heat dissipation structure includes an inlet 104 and an outlet 105, a heat dissipation path is formed between the inlet 104 and the outlet 105, at least a portion of the phototherapy assembly 300 is located on the heat dissipation path, and the heat dissipation plate 302 of the phototherapy assembly 300 is located on the heat dissipation path. A cooling source 200 is provided upstream of the phototherapy unit 300, and the cooling source 200 delivers a flowing cooling medium into the heat radiation path. The cold source 200 outputs the flowing cooling medium and passes through the position of the heat dissipation plate 302, and brings out the heat generated at the phototherapy assembly 300 from the outlet 105.

Specifically, the heat sink 400 is made of the same material as the heat sink 302. Preferably aluminum. The heat sink 400 includes a base plate 403 and fins 401, the base plate 403 being fixed to the surface of the heat dissipation plate 302; the fins 401 are arranged in plurality on the base plate 403, and heat dissipation channels 402 are arranged between adjacent fins 401 or on each fin 401 and located on the heat dissipation path. The cooling medium passes through the heat dissipation channels 402 on the plurality of fins 401, so that the heat dissipation area can be increased, the cooling medium is transferred from the circuit board 301 to the heat dissipation plate 302, and heat dissipation is performed from the surfaces of the plurality of fins 401, thereby improving the heat dissipation efficiency.

In an embodiment, the heat dissipation channel 402 is linear or folded or curved or wavy. The contact area with the air flow can be increased by various shapes, and the heat dissipation effect is improved.

In this embodiment, the heat dissipation channel 402 extends along the heat dissipation path direction, so as to reduce the flow resistance of the cooling medium, increase the flow speed of the cooling medium, and increase the heat exchange efficiency of heat transfer, thereby improving the heat dissipation efficiency.

A diversion channel 700 forming a heat dissipation path is arranged between the rear cover 102 and the phototherapy assembly 300, specifically between the rear cover and the heat dissipation plate 302, and the inlet 104 and the outlet 105 are communicated with the diversion channel 700.

In this embodiment, the cold source 200 is preferably a wind source, which is disposed at the inlet 104 of the rear cover 102, where the wind source is a fan, and may be other blower devices. The impeller of the fan rotates and conveys flowing air flow into the heat dissipation path, heat can be taken away rapidly by adopting air source blowing, and the frame 101, the heat dissipation plate 302, the fins 401 and the circuit board 301 are subjected to faster heat dissipation, so that the stability of configuring the high-power light source is improved.
