When the laser irradiates the skin of the user, the regrowth of the hair of each part of the body can be effectively prevented. However, when the light emitting assembly 20 is operated, heat may be generated inside, and the heat may cause the internal temperature of the epilation instrument 100 to rise, thereby affecting the use safety of the epilation instrument 100.

When the air flow passes through the light emitting component 20, heat on the light emitting component 20 is carried away by the air flow, so that the temperature of the light emitting component 20 is reduced, and the normal use of the epilation instrument 100 is ensured.

Specifically, referring to fig. 2 and 3, the housing 10 may include a head 11 and a handle 12, and both the head 11 and the handle 12 may be connected to each other to form one body. As shown in fig. 2, the head 11 may include a first direction L1 and a second direction L2, and the head 11 and the handle 12 are sequentially arranged in the first direction L1. The handle 12 is used for holding by a user to help the user to better grasp and operate the epilation instrument 100 to ensure the epilation effect of the epilation instrument 100. Because the handle 12 is easily accessible, the user can hold for a long period of time, reducing the fatigue caused by long-term holding. The handle 12 comprises a first side 121 and a second side 122 distributed along the second direction L2, the first side 121 being adapted to be gripped by a thumb and an index finger of a user, the second side 122 being adapted to be grasped by the palm of the hand. This design provides a good grip and makes handling more natural and convenient. The head 11 protrudes and forms the protruding portion 113 relative to the first side 121 of the handle 12 in the second direction L2, and the protruding portion 113 forms the light emitting surface 1131 on a side, away from the handle 12, of the second direction L2, so that the head 11 can be better perceived and operated by a user, and the protruding portion 113 can extend outwards, so that interference of hands on the epilator 100 is reduced. In use, the distance between the light exit surface 1131 and the skin may be shortened. The light exit surface 1131 is provided with a light exit 1132, and the area ratio of the light exit 1132 to the light exit surface 1131 may be 1/4, 1/3, or 1/2, which is not limited in this embodiment.

Preferably, referring to fig. 3 and 4, a first heat dissipation member 1133 is disposed on a side of the protrusion 113 away from the light-emitting surface 1131, the first heat dissipation member 1133 includes a semiconductor refrigeration member, a heat pipe and a heat sink, the semiconductor refrigeration member includes a cold end and a hot end, and the cold end and the hot end mutually transfer heat. The cold end abuts against one side of the protruding portion 113 away from the light-emitting surface 1131, and heat of the light-emitting surface 1131 can be absorbed by the cold end. The cold junction transmits heat to the hot junction, and the hot junction is connected with the heat pipe, and accessible heat pipe transmits heat to the fin on, and the fin is arranged in second wind channel 125, and the air current is through can taking away the heat of fin, and then reduces the temperature of play plain noodles 1131, avoids taking place the condition of scalding the user.

The inside of the head 11 is provided with a first air duct 114, and the head 11 can effectively guide the wind flow. The head 11 is provided with an air outlet 115 communicated with the first air duct 114, the handle 12 is provided with a first air inlet 123, and air flow can enter from the first air inlet 123 and flow out from the air outlet 115 under the drive of the fan 30 so as to realize smooth flow of the air flow. The number of the first air inlets 123 may be plural, the first air inlets 123 may be spaced apart from the first side 121 of the handle 12, and the first air inlets 123 may ensure a sufficient air intake amount. And the aperture of the single first air inlet 123 may be reduced to refine the air flow entering the fan 30 so that the air flow can flow more smoothly. The air flow can be filtered to prevent foreign matters from entering the depilating apparatus 100. The area where the plurality of first air inlets 123 are located forms an air inlet surface 124, which may facilitate increasing the effective area of the first air inlets, thereby enhancing the air intake capacity of the handle 12 portion.

The air inlet surface 124 is gradually inclined towards the second side 122 of the handle 12 from the end close to the light outlet surface 1131 to the end far from the light outlet surface 1131 in the first direction L1, and an included angle between the rotation axis of the fan 30 and the second direction L2 is an acute angle, for example, an included angle between the rotation axis of the fan 30 and the second direction 112 may be 10 ° -40 °, and the first air inlet 31 of the fan 30 faces the first air inlet 123. The fan 30 is disposed obliquely with respect to the second direction L2, which is advantageous in downsizing the handle 12. And the air intake surface 124 is also disposed obliquely with respect to the second direction L2. The air inlet surface 124 can incline corresponding to the fan 30, the air inlet amount of the first air inlet 123 is larger, the heat dissipation effect is ensured, and the working efficiency of the dehairing instrument 100 is improved. Moreover, the inclination angle of the fan 30 in this embodiment is moderate, so that air is not easy to enter due to too much inclination, and the handle 12 is large due to too little inclination, which is not beneficial to miniaturization.

With continued reference to fig. 1 and 3, at least a portion of the fan 30 is mounted to the handle 12, and the fan 30 is adapted to direct the airflow from the first air inlet 123 to the first air duct 114 and out the air outlet 115. The arrangement of at least part of the fan 30 mounted to the handle 12 in this embodiment not only enhances the operational stability of the fan 30, but also facilitates use by the operator. The operator can more easily manipulate the handle 12 to better control the rotational angle and speed of the fan 30.

In one embodiment, referring to fig. 3, a second air duct 125 is further disposed in the handle 12, the air outlet 115 is connected to the first air duct 114, and the first air duct 114 and the second air duct 125 are connected to each other. The first air inlet 123 is communicated with the second air duct 125, the fan 30 is arranged in the second air duct 125, the fan 30 is arranged at one end of the second air duct 125, the fan 30 can suck air from the first air inlet 123, and air flows to the first air duct 114 through the second air duct 125. The air flow passes through the light emitting assembly 20 to absorb heat of the light emitting assembly 20 in the flowing process, and then flows out from the air outlet 115 to carry the heat away from the epilator 100, so as to ensure normal operation of the epilator 100. The included angle between the extending direction of the first air duct 114 and the extending direction of the second air duct 125 may be an acute angle, for example, the included angle between the extending direction of the first air duct 114 and the extending direction of the second air duct 125 may be 10 ° -40 °, for example, the included angle between the extending direction of the first air duct 114 and the extending direction of the second air duct 125 may be 10 °, 20 °, 30 °, 40 °, etc., which is not limited in this embodiment. Such an angular arrangement may allow for smoother air flow and reduced noise. And, have certain contained angle between first wind channel 114 and the second wind channel 125, avoid the problem of gaseous backward flow to a certain extent, avoid flowing back to the air current of first wind channel 114 to take place to flow back, flow back to second wind channel 125 again. Specifically, the bending between the first air duct 114 and the second air duct 125 is prevented from being too large, the air flow is prevented from being affected, and the volume and shape of the epilation instrument 100 are also changed, which is not beneficial to the miniaturization design. Too small a bending degree between the first air duct 114 and the second air duct 125 is avoided, the effect of blocking the air flow from flowing back is poor, and the heat dissipation effect of the epilation instrument 100 is ensured.

Preferably, the width of the first air duct 114 may be 1.5-2 times the width of the second air duct 125. The flow of the air flow in the second air duct 125 can be made more stable, thereby more effectively introducing the air flow into the first air duct 114. Also, as the width of the first air duct 114 increases, the cross-sectional area of the first air duct 114 increases. When the air flows to the first air duct 114, the pressure of the air decreases, and the flow speed is reduced. The air flow can fully contact with the light emitting component 20 in the first air duct 114, so that the heat dissipation effect is improved. The larger first air duct 114 can facilitate the arrangement of the light emitting assembly 20, and ensure that the air flow can smoothly emit air from the air outlet 115.

In an embodiment, referring to fig. 1 and 3, the housing 10 further includes at least one second air inlet 117, the second air inlet 117 is formed in the handle 12 and located between the first side 121 and the second side 122 of the handle 12, the second air inlet 117 is communicated with the second air duct 125, and when an operator uses the depilating apparatus 100, air flow can also enter through the second air inlet 117, so as to improve the working efficiency and the use safety of the depilating apparatus 100. The fan 30 may be a centrifugal fan 30, the centrifugal fan 30 having a rotational axis (as shown by the dashed line in fig. 3), the centrifugal fan 30 being capable of taking in air in the direction of the rotational axis and taking out air in the radial direction. Referring to fig. 3 and 4, the centrifugal fan 30 has a high air intake capability and low noise. The fan 30 is provided with a first air inlet 31 and a second air inlet 32 on opposite sides thereof, the first air inlet 31 faces the first air inlet 123, and the second air inlet 32 is communicated with the second air inlet 117. The epilating apparatus 100 is enabled to better suck in air and to better introduce air into the interior of the housing 10 for cooling. The minimum distance between the first air inlet 123 and the second air inlet 117 in the second direction L2 is 5mm-15mm. The first air inlet 123 and the second air inlet 32 are separated by a certain distance and are respectively communicated with the two air inlets of the fan 30, so that the air inlet quantity can be increased, and the situation that the air inlet in one area cannot be used for air inlet after being blocked by the hand of a user is avoided. This distance in turn ensures an efficient circulation of air and at the same time prevents the operator from being disturbed too much when using the epilation instrument 100.

With continued reference to fig. 3, the housing 10 is provided with a first mounting plate 118 and a second mounting plate 119, where the first mounting plate 118 and the second mounting plate 119 may be made of metal, for example, the first mounting plate 118 and the second mounting plate 119 may be made of aluminum alloy, and the first mounting plate 118 and the second mounting plate 119 may enhance the structural strength of the housing 10.

The fan 30 is mounted between the first mounting plate 118 and the second mounting plate 119 such that the fan 30 is capable of efficiently drawing air in and directing the air into the first air duct 114 through the second air duct 125. The first mounting plate 118 and the housing 10 define an air guide channel 1171, and the air guide channel 1171 communicates with the second air inlet 117 and the second air inlet 32. The air flow is guided to smoothly enter the fan 30 from the second air inlet 117 and the second air inlet 32, and the fan 30 can drive the air flow to flow towards the first channel and the second channel, so as to ensure the air inlet quantity of the fan 30.

The casing 10 is provided with a connecting air duct 51 between the second air duct 125 and the first air duct 114, and the width of the connecting air duct 51 gradually increases from one end near the second air duct 125 to one end near the first air duct 114. The spatial variation from the first air duct 114 to the second air duct 125 can be slowed down, and thus, the air vortex generated due to the rotation of the fan 30 and the like can be reduced, so that the air can flow more smoothly. Illustratively, the length of the connecting duct 51 may be 0.1-0.2 times the sum of the lengths of the first duct 114 and the second duct 125, avoiding the connecting duct 51 from being too short, resulting in rapid airflow changes and vortex generation.

The width of the air inlet cavity 1172 is 15mm-35mm, which can ensure enough air quantity to enter, ensure the flow rate of air flow and is beneficial to keeping the strength and the hand feeling of the handle 12. Illustratively, the centrifugal fan 30 further includes a fan housing surrounding the centrifugal fan 30, the fan housing may be connected to the second mounting plate 119 or integrally formed therewith, and a through hole is provided at an intersection of the fan housing and the rotation axis of the centrifugal fan 30, so as to better communicate the air guide channel 1171 with the air inlet cavity 1172.

The light emitting component 20 is disposed on the head 11 and at least partially located in the first air duct 114, so that the light emitting component 20 can effectively guide an air flow, and the air flow passes through the light emitting component 20 to reduce the overall temperature of the light emitting component 20, thereby ensuring that the light emitting component 20 can work normally.

The lamp 21 is disposed at a side of the lamp shade 22 facing the light-emitting surface 1131, and when the lamp 21 works, the lamp shade 22 can reflect the light emitted by the lamp 21, so that the light is concentrated and emitted on the light-emitting surface 1131, and the light with higher light intensity can be emitted from the light-emitting opening 1132. The lamp 21 and the lamp housing 22 are at least partially located within the first air duct 114. The lamp shade 22 is illuminated by the lamp tube 21, the surface temperature of the lamp shade 22 is higher, when the external air current passes through the first air duct 114, the heat generated by the operation of the lamp tube 21 and the heat of the lamp shade 22 can be carried away by the air current, and then the temperature of the lamp tube 21 and the temperature of the lamp shade 22 are reduced, so that abnormal conditions caused by overhigh temperature are avoided.
