The current depilatory instrument sets up a heat dissipation component inside to dissipate heat for the light source and the interior of the depilatory instrument, but still has some problems, such as the unsatisfactory heat dissipation effect, the excessively large volume of the heat dissipation component and the like.

[0003] On the other hand, the current mainstream depilatory instrument adopts a light-transmitting crystal, a sleeve ring and a contact piece to form a cold compress head for contacting the skin, and the light-transmitting crystal is only arranged in a smaller area in the middle of the cold compress head, that is, the light irradiation area of the depilatory instrument is smaller, which is inconvenient for the user to use and has low efficiency, such as the portable depilatory instrument disclosed in Chinese patent CN211633558U, in which the light-transmitting crystal is arranged inside the depilatory instrument, and the contact part for contacting the skin only forms a smaller window for irradiating laser.

[0033] The technical scheme of the present application will be described in further detail below in combination with the drawings and specific embodiments, so that the person skilled in the art can better understand the present application and implement it, but the embodiments are not used as the limitation of the present application. In the present embodiment, it should be understood that the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only used for the purpose of describing the present application, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0034] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element and integrated as a whole, or there can be a middle element. The terms "mounting", "one end", "the other end" and similar expressions used in the present application are only for the purpose of illustration.

[0035] The laser hair removal instrument is based on the selective photothermal dynamics principle, and through reasonable adjustment of laser wavelength, the light beam can penetrate the skin surface and be finally absorbed by the hair follicle. Through selective absorption of laser energy, the hair follicle is damaged, so that the hair loses the regenerative ability, and the surrounding tissue is not damaged. At present, the laser hair removal instrument used by individuals on the market generally uses semiconductor laser and intense pulsed light (IPL) as light source. The advantage of IPL is that it can treat multiple skin problems at the same time, because its spectrum is wide, in addition to hair removal, it can also improve skin pigmentation, vascular dilation and other problems, and it has relatively small stimulation to the skin, and is especially suitable for people with sensitive skin. IPL is not a strict laser, but a high-intensity, wide-spectrum light source, and its wavelength range is generally between 400-1200nm. Without effective heat dissipation design, the temperature at the IPL light source and the temperature at the skin contact position can quickly rise above 100℃, which can burn the skin and damage the hair removal instrument. Therefore, on the one hand, the heat dissipation of the light source part needs to be considered, and on the other hand, the cooling of the part of the hair removal instrument in contact with the skin needs to be considered to avoid burning the skin.

[0036] Please refer to Figures 1-6 The utility model embodiment provides a kind of depilator, it includes shell 1, and air inlet hole 101 and heat dissipation hole 102 are set on shell 1;Depilation mechanism 2, depilation mechanism 2 is set in shell 1 and is set in the end of depilator;First heat dissipation device 301 and second heat dissipation device 302, first heat dissipation device 301 and second heat dissipation device 302 are adjacent to the setting of depilation mechanism 2;Depilation mechanism 2 includes refrigeration component 307, cold compress piece 201 and light source component 310, and cold compress piece 201 is set in the end of depilator, and it is the end surface of depilator in contact with skin;Cold compress piece 201, refrigeration component 307 and first heat dissipation device 301 are sequentially connected, and first heat dissipation device 301 is used to heat dissipation for refrigeration component 307;Light source component 310 is set on one side of second heat dissipation device 302, and air inlet hole 101, second heat dissipation device 302 and heat dissipation hole 102 form second heat dissipation air duct, for heat dissipation for light source component 310. Specifically can refer to Figure 6 Arrow in the figure indicates the direction of air flow.

[0037] It can be understood that cold compress piece 201 is set in the end of depilator and it is the end surface of depilator in contact with skin, which means that the part of depilator in contact with skin is cold compress piece 201, and other components are not included. Relative to the depilator on the market, the end surface of the depilator of the embodiment is cold compress piece 201, and when using the depilator, it has greater cold compress area, and the user has better use experience.

[0038] It can be understood that the air inlet hole 101 is arranged as a plurality of spaced small holes penetrating through the lower shell 104, which can increase the air inlet area and air inlet amount to improve the heat dissipation effect. In addition, the air inlet hole 101 is arranged at the upper part of the epilator, where the upper part refers to the side close to the skin contact end of the epilator. On the one hand, the air inlet hole 101 is closer to the epilation mechanism 2, reducing the flow distance of the cold air and dissipating heat to the epilation mechanism 2 faster. On the other hand, the holding part of the epilator is generally arranged at the lower part of the epilator, i.e. the user holds the lower part of the epilator during use, so that the air inlet hole 101 arranged at the upper part is not blocked, thereby affecting the heat dissipation effect.

[0039] In addition, the first heat dissipation device 301 is arranged to cool the refrigeration component 307, and the second heat dissipation device 302 is arranged to cool the light source component 310, so that the double-channel heat dissipation of the epilation mechanism 2 can greatly improve the heat dissipation efficiency and effect.

[0040] Please refer to Figures 5-8 In the embodiment, the end of the shell 1 is provided with a mounting ring 105 fixedly connected with the shell 1 for fixing the cold compress patch 201. The mounting ring 105 is provided with a first opening 106 facing the outer side and an abutting portion 107 arranged on the inner wall. The abutting portion 107 is provided with an abutting platform 108 on the side facing the first opening 106 for limiting the position of the cold compress patch. The cold compress patch 201 is fixed between the first opening 106 and the abutting portion 107. It can be understood that the outer side refers to the side facing the skin during use of the epilator.

[0041] In one embodiment, the shape of the first opening 106 corresponds to the cold compress patch 201, and the inner diameter of the first opening 106 is greater than the outer diameter of the cold compress patch 201, i.e. the size of the first opening 106 is greater than that of the cold compress patch 201, so that the cold compress patch 201 is limited within the first opening 106 or flush with the first opening 106. The abutting portion 107 is arranged as a slope structure facing the outer side. It can be understood that the slope structure facing the outer side specifically refers to the shape of the abutting portion 107 forming a slope, and the slope angle faces the outer side of the epilator, and the slope surface faces the inner side of the epilator. During installation, the cold compress patch 201 slides along the slope surface of the slope structure, and is clamped between the first opening 106 and the abutting portion 107 after passing over the slope structure.

[0042] In another embodiment, the cold compress patch 201 is installed into the first opening 201 and abuts on the abutting platform 108, and is fixed with the inner wall of the mounting ring 105 by adhesion. At this time, the outer side of the cold compress patch 201 is flush with the outer side of the mounting ring 105.

[0043] Please refer to Figure 5In the preferred embodiment, the outer side end surface of the mounting ring 105 forms a contact surface for the epilator to contact the skin with the outer side surface of the cold compress piece 201, and the area ratio of the outer side surface of the cold compress piece 201 to the contact surface is greater than 0.85, that is, the area of the cold compress piece 201 accounts for more than 85% of the area of the contact surface. Compared with the small cold compress window of the existing epilator, the contact surface of the epilator of the present embodiment has a larger cold compress area, and the user has a better experience when using the epilator.

[0044] In the preferred embodiment, the cold compress piece 201 is a transparent crystal, which can be a sapphire crystal, glass, etc., and has a small effect on the light source. The thickness of the transparent crystal is 1-5 mm. Optionally, the thickness of the transparent crystal can be 1 mm, 2 mm, 3 mm, 4 mm, or 5 mm. A lower thickness of the transparent crystal helps to dissipate heat inside the epilator. In further embodiments, the width-to-thickness ratio of the transparent crystal is greater than 30. It can be understood that the width of the transparent crystal refers to the distance at the widest point of the transparent crystal, and a width-to-thickness ratio greater than 30 indicates that the transparent crystal has a large size and a small thickness. The existing epilator often uses a large-size, thick square transparent crystal. This type of epilator has a limited light irradiation area and a limited skin cooling area. The epilator of the present embodiment positions the transparent crystal as a thin sheet in front of the front end of the epilator, which not only increases the cooling area and light transmission area of the epilator, but also reduces the effect of the transparent crystal on the light source, making the epilator more effective.

[0045] Please refer to Figures 7-8 In the preferred embodiment, the housing 1 has a second opening 109 at one end facing the cold compress piece 201, the refrigeration component 307 is connected to the cold compress piece 201 through the second opening 109, and the light source component 310 irradiates light to the cold compress piece 201 through the second opening 109. The area of the cold compress piece 201 is greater than the opening area of the second opening 109. Specifically, the housing 1 includes an upper housing 103 and a lower housing 104, which are assembled together to form a containing cavity containing components such as the epilator mechanism, the first heat dissipation device, and the second heat dissipation device. The containing cavity is provided with a second opening 109 at one end facing the user, and the second opening 109 is used for connecting the cold compress piece 201 to other components. The area of the cold compress piece 201 is greater than the opening area of the second opening 109. It can be understood that the area of the cold compress piece 201 is greater than the area of the refrigeration component 307, that is, the epilator has a larger cooling area than the refrigeration component 307 and the second opening 109 through the cold compress piece 201.

[0046] Please refer to Figures 7-8In the preferred embodiment, the inner wall of the mounting ring 105 is further provided with a plurality of protrusions 111, and the shell is provided with corresponding clamping grooves 110, the protrusions 111 are clamped and connected with the clamping grooves 110 to fix the mounting ring 105 and the shell 1. Alternatively, the shell 1 extends outwardly on the side facing the mounting ring 105 to form a mounting portion, the clamping grooves 110 are opened on the mounting portion, and the mounting ring 105 is sleeved on the mounting portion and the protrusions 111 are clamped on the clamping grooves 110, so as to fix the mounting ring 105.

[0047] Please refer to Figures 2-3 , Figure 6 In the preferred embodiment, the first heat dissipation device 301 is a heat pipe radiator component, the main body of the heat pipe radiator component is a heat pipe radiator, and the heat pipe of the heat pipe radiator mainly consists of a pipe shell, a wick and a working medium. When the evaporation section (hot end) of the heat pipe is heated, the working medium vaporizes after absorbing heat, and the vaporized steam flows from the evaporation section to the condensation section (cold end) of the heat pipe under the action of a small pressure difference. In the condensation section, the steam releases latent heat and condenses into liquid when it is cold. Then, the liquid returns to the evaporation section under the capillary action of the wick or the action of gravity, and the cycle is repeated to achieve efficient heat transfer from the hot end to the cold end. The first end 305 of the heat pipe radiator component is fixedly connected with the refrigeration component 307 for heat dissipation of the refrigeration component 307. Alternatively, the refrigeration component 307 can adopt a refrigeration sheet, and a larger refrigeration area can effectively reduce the temperature. The first end 305 of the heat pipe radiator component is connected with the refrigeration component 307. It can be understood that the refrigeration sheet, also known as a thermoelectric refrigeration sheet, works based on the Peltier effect. When an electric current passes through a loop composed of N-type and P-type semiconductors, heat absorption or heat release occurs at the junction of the two types of semiconductors. While one side of the refrigeration sheet absorbs heat to cool, the other side will necessarily release heat to the interior space of the epilator. In this embodiment, the first end 305 (hot end) of the heat pipe radiator component is connected with the refrigeration component 307, which can directly absorb the heat of the refrigeration component 307 to dissipate heat for the refrigeration component 307, and the heat absorbed by the heat pipe radiator component is transferred to the second end 306 (cold end). The second end 306 of the heat pipe radiator component is arranged between the air inlet hole 101 and the second heat dissipation device 302. It can be understood that the cold air entering from the air inlet hole 101 will first flow through the second end 306 of the heat pipe radiator component to dissipate heat, which can greatly improve the heat dissipation effect, and the heat pipe radiator component also performs a cold and hot cycle.

[0048] Please refer to Figures 2-3In the preferred embodiment, a plurality of adjacent fins 308 are arranged on the second end 306 of the heat pipe radiator component, and the adjacent fins 308 form an air inlet channel 309 which is in communication with the air inlet hole 101 and the second heat dissipation device 302. It can be understood that the air inlet channel 309 is arranged vertically with the air inlet hole 101, and the air inlet channel 309 is in communication with the air inlet hole 101 and the second heat dissipation device 302, and the cold air enters the air inlet channel 309 from the air inlet hole 101, and then enters the second heat dissipation device 302, and finally is discharged from the heat dissipation hole 102. The fins 308 are directly mounted on the second end 306 of the heat pipe radiator component, which can transfer heat through direct contact to dissipate heat from the second end 306, and on the other hand, the air inlet channel 309 formed by the adjacent fins 308 can increase the air inlet flow rate, and the contact area between the fins 308 and the cold air is large, which can effectively improve the heat dissipation effect.

[0049] Please refer to Figures 2-3 、 Figure 6 In the preferred embodiment, the second heat dissipation device 302 includes a fan component 318 and an air duct component 4, the air duct component 4 is provided with a first port 313 and a second port 314, and the air duct component 4 forms a one-way flow channel from the first port 313 to the second port 314; the fan component 318 can be a turbine fan or a bracket fan, and a smaller power can provide a larger air volume.

It can be understood that when the fan component 318 works, the cold air enters the epilator from the air inlet hole 101, enters the air inlet 303 of the fan component 318 and flows out from the air outlet 304, in this process, the fan component 318 accelerates the flow rate and flow of the cold air; the cold air flows from the air outlet 304 to the first port 313 of the air duct component 4, and then flows out from the second port 314, and the cold air flowing through the light source component 310 dissipates heat, and the heat dissipation effect is good.

[0050] Please refer to Figure 6In the preferred embodiment, the light source component 310 includes a light source 311, a reflector 312 and a filter 319, which are mature technologies in the field of hair removal devices and will not be described here. Please refer to the applicant's prior application CN215384597U. The light source 311, the reflector 312 and the filter 319 are arranged in the air duct component 4, and the fan component 318 and the air duct component 4 form a one-way second heat dissipation air duct for dissipating heat for the light source component 310. The cold air from the air inlet 303 is blown to the light source component 310 through the second heat dissipation air duct, at the same time, the heat of the light source component 310 is taken away, and flows out from the heat dissipation hole 102, which can effectively dissipate heat for the light source component 310.

[0051] Please refer to Figure 6 In the preferred embodiment, the air outlet 304 includes a first air outlet 315 and a second air outlet 316, the first air outlet 315 is in communication with the first port 313 of the air duct component 4, and the second air outlet 316 is arranged towards the lower part of the hair removal device.

Please refer to Figure 6 The arrow in the figure represents the direction of air flow. The second air outlet 316 is towards the lower part of the hair removal device, that is, after the cold air enters the fan assembly, a part of the cold air is blown to the inside of the hair removal device from the second air outlet 316, which can dissipate heat for the electrical components, power supply 5, etc. inside the hair removal device, thereby prolonging the service life of the hair removal device.

[0052] Please refer to Figures 2-3 In the preferred embodiment, the hair removal device further includes an inner shell 7 arranged between the shell 1 and other components, for mounting and / or fixing other components, such as the hair removal structure, the first heat dissipation device 301, the second heat dissipation device 302 and the circuit board, etc. It can be understood that the inner shell 7 is fixedly connected with the shell 1, and the inner shell 7 is provided with a plurality of mounting positions and connecting positions, which are used for mounting other components on one hand, and providing mounting positions on the other hand, and can also play a supporting role.
