The use of "including," "comprising," "having," and the like, herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. In particular, when "a certain element" is described, the present invention is not limited to the number of the element being one, and may include a plurality of the elements.

As shown in FIGS. 1-10, the present invention provides an epilating apparatus 10 with thermal isolation, the epilating apparatus 10 includes a housing 101 and a plurality of electronic modules disposed in the housing 101. In the present embodiment, the electronic modules include an epilation element, a heat dissipation element and a control circuit board 102 disposed in the housing 101.

Specifically, the hair removal assembly is composed of a light emitting unit 106, and the light emitting unit 106 includes a mounting bracket, a lamp holder 1066 mounted on the mounting bracket, a lamp cup 1067 disposed in the lamp holder 1066, a flash 1068 fixed to the lamp cup 1067, and a light blocking member 1069 sleeved on the flash 1068. The flash lamp 1068 is electrically connected to the control circuit board 102, and irradiates light with a specific wavelength onto the skin surface of a human body as required, so that hair follicles on the skin of the human body are necrotic due to absorption of sufficient light energy, thereby achieving the effect of hair shedding. Accordingly, the front end of the housing 101 is provided with a light exit port 105 at a position corresponding to the light emitting unit 106.

In the illustrated embodiment, as shown in fig. 3 and 5, the housing 101 includes a front shell 1011 and a rear shell 1012, which are detachably connected by a snap connection or a fixing member such as a screw, so as to facilitate assembly and maintenance of the internal electronic module, and the light outlet 105 is disposed at the front end of the front shell 1011. Preferably, the light outlet 105 is further provided with sapphire 116 and quartz glass 117, which can improve the transmittance of light emitted from the light outlet 105, so that energy can reach the deep layer of hair follicle, thereby achieving the purpose of effective depilation; in addition, the plane light outlet of the sapphire 116 can be rapidly cooled to protect the skin surface. As shown in fig. 3, a filter assembly 118 is further disposed between the light outlet 105 and the flash 1068 to filter light.

For example, the isolation unit 107 is some combined components capable of conducting and insulating heat, such as a component formed by depositing copper wires, ceramic-based circuit boards, and the like on a ceramic substrate, so that the output current of the control circuit board 102 reaches the light emitting unit 106 through the isolation unit 107, but the heat generated by the power supply of the light emitting unit 106 is not substantially conducted to the control circuit board 102, and further, the heat is prevented from being further conducted to the housing 101 through the control circuit board 102 to form a high temperature point on the housing 101, which affects the use and safety of the product. Preferably, the thermal conductivity of the isolation unit 107 is lower than that of a metal material.

In the illustrated embodiment, as shown in fig. 8 to 10, the isolation unit 107 includes a heat insulation substrate 1071, and a left lamp socket 1072 and a right lamp socket 1073 disposed on both sides of the heat insulation substrate 1071, wherein the heat insulation substrate 1071 is soldered to the control circuit board 102, the light emitting unit 106 is mounted on the heat insulation substrate 1071, and the contact point of the flash lamp 1068 is electrically connected to the left lamp socket 1072 and the right lamp socket 1073.

In other embodiments, the thermal insulation substrate 1071 may also be mounted on the housing 101, for example, on the inner wall of the housing 101, and also may serve to insulate the heat generated by the light emitting unit 106 in the housing 101, thereby preventing the formation of high temperature spots on the housing 101. Alternatively, two insulating substrates 1071 are provided, one insulating substrate 1071 is mounted on the control circuit board 102 and the other insulating substrate 1071 is mounted on the case 101, further enhancing the thermal insulation effect.

Due to the arrangement of the heat pipe, the heat sink 112 may be mounted at a suitable hole position in the housing 101 and spaced apart from the light emitting unit 106. Through the effect of the refrigeration element 111, the heat generated by the light emitting unit 106 can be conducted to the heat sink 112 for dissipation, and the heat sink 112 is usually a fin-type structure, and has a large heat exchange area, so that the heat dissipation effect can be effectively improved. Preferably, the heat sink 112 is disposed in a ventilation air duct of the fan 1063, and the air flow of the fan 1063 can take away the heat emitted by the heat sink 112, so as to prevent the hot air from being retained in the casing 101.
