Description

Technical Field

[0001] The utility model relates to the technical field of beauty equipment, in particular to a skin treatment device. Background Art

[0002] Skin treatment devices include beauty equipment such as hair removal devices and photon skin rejuvenation devices. Hair removal devices and photon skin rejuvenation devices are used to treat the skin to achieve beauty effects. Half of the hair removal devices currently on the market use intense pulsed light beams to irradiate the skin. The light energy is absorbed by the hair follicles, generating heat energy to destroy the hair follicles, thereby achieving the therapeutic effect of hair removal. Photon skin rejuvenation devices use intense pulsed light to act on skin tissue to produce photothermal and photochemical effects, which rearrange the collagen fibers and elastic fibers deep inside, restore elasticity, and improve skin condition. In the existing skin treatment devices, due to the large amount of heat generated by the laser, a burning pain sensation will be caused to the skin during operation. The existing skin treatment devices generally select sapphire as the light-transmitting component so that when it contacts the human skin in the working state, the skin will not produce a burning sensation. In order to maintain the continuous cooling sensation of the light-transmitting component on the skin, it is usually necessary to set the cold end of the refrigeration component to fit with the light-transmitting component. In order to ensure that the light incident surface of the light-transmitting component is not blocked, the existing skin treatment devices usually set the refrigeration component on the side of the light-transmitting component, which increases the thickness of the light-transmitting component, thereby increasing the cost. In addition, due to the limitation of the light-emitting surface area of ​​the light-transmitting component located at the light outlet and the fact that the refrigeration component also needs to occupy a certain space, the light-emitting area and the refrigeration area of ​​the light-transmitting component will be reduced, and the cooling capacity output to the skin will be reduced, thereby causing a reduction in the cooling effect and the light-emitting efficiency. In addition, as the thickness of the light-transmitting component increases, the heat exchange between the light-transmitting component and the surrounding environment in the thickness direction causes a large loss of cooling capacity, thereby reducing the cooling efficiency.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1 and Figure 2 The present invention provides a skin treatment device 1. The skin treatment device 1 includes, for example, a hair removal device, a photorejuvenation device, and the like for treating the skin. In the embodiment of the present application, the skin treatment device 1 includes, for example, a light source assembly 100, a light-transmitting element 200, and a cooling element 400. Figure 1The skin treatment device 1 further includes, for example, a shell 800 , which is used to support and protect components disposed inside the skin treatment device 1 .

[0032] Specifically, the light-transmitting member 200 has, for example, a light-entering surface 210 and a light-emitting surface 220, and the light-entering surface 210 is arranged corresponding to the light source assembly 100, and the light-entering surface 210 is used to guide the light generated by the light source assembly 100 into the light-transmitting member 200. The cooling member 400 is, for example, arranged between the light-transmitting member 200 and the light source assembly 100. Among them, the light source assembly 100 is used to generate light, and can be other light sources such as IPL laser or halogen lamp. The light-transmitting member 200 is, for example, sapphire, etc., which is used to enable the light generated by the light source assembly 100 to pass through the light-transmitting member 200 and irradiate the skin. The cooling member 400 is, for example, a semiconductor cooling sheet, which is used to cool the light-transmitting member 200 to reduce the burning sensation and pain generated by the skin treatment device 1 when treating the skin. The cooling element 400 contacts the light incident surface 210, and at least a portion of the light incident surface 210 is exposed from the cooling element 400. In the present embodiment, the cooling element 400 is, for example, disposed at an edge portion of the light incident surface 210, and a central portion of the light incident surface 210 is used to transmit light generated by the light source assembly 100 to ensure a sufficient area of ​​the light incident surface 210, so that more light energy can be transmitted from the light incident surface 210 to the light emitting surface 220, thereby improving the light emitting effect of the skin treatment device 1.

[0033] In this embodiment, taking the skin treatment device 1 as an epilator as an example, when the epilator is used for epilation, the light source assembly 100, such as an IPL lamp, generates a laser beam, which is emitted onto the skin through the light-transmitting member 200, and the cooling member 400 is arranged on the light-entering surface 210 of the light-transmitting member 200 and the cooling member 400 contacts the light-entering surface 210. By setting the cold end of the cooling member 400 in contact with the light-entering surface 210, the cooling capacity of the cooling member can be transferred to the light-transmitting member 200, so as to cool the light-transmitting member 200, so as to reduce the high temperature burning sensation when the IPL lamp is emitted during epilation. In the prior art, the epilator of the prior art arranges the cooling member 400 on the side of the light-transmitting member 200, which increases the thickness of the light-transmitting member 200, thereby increasing the manufacturing cost. In addition, since the light-transmitting member 200 is usually arranged on the light outlet of the shell 800, the light-emitting area of ​​the light-emitting surface 220 of the light-transmitting member 200 is also limited by the light outlet, and the refrigeration member 400 also needs to occupy a certain space, the light-emitting area and the refrigeration area of ​​the light-emitting surface 220 of the light-transmitting member 200 will be reduced, and the refrigeration effect and light-emitting efficiency cannot be improved. Furthermore, in the prior art, the refrigeration member 400 is arranged on the side of the light-transmitting member 200, and the light-transmitting member 200 is usually made into a hexahedron. Except for the side contacting the refrigeration member 400, the other surfaces not contacting the refrigeration member 400 will exchange heat with the air or the shell, etc., thereby causing the light-transmitting member 200 to lose refrigeration capacity. In order to solve the problem of low light emission and cooling effects in the prior art, the thickness of the light transparent member 200 is generally made thicker, that is, the thickness of the light transparent member is increased. As the thickness of the light transparent member increases, the area of ​​the surface that is not in contact with the refrigeration member will also increase, resulting in more cooling capacity lost after heat exchange. However, the present application arranges the refrigeration member 400 on the light incident surface 210 of the light transparent member 200, so that the light emission area and cooling area of ​​the light transparent member 200 are larger, and the thickness of the light transparent member 200 can be thinned. Therefore, the smaller the area of ​​the light transparent member 200 exchanging heat with the air, the smaller the cooling capacity loss.

[0034] The skin treatment device 1 provided by the embodiment of the utility model has a cooling element 400 disposed on the light incident surface 210 of the light transmissive element 200, so that the cooling element 400 can cool the light transmissive element 200, and the cooling element 400 is disposed in contact with the light incident surface 210 of the light transmissive element 200, so that the cooling element 400 does not affect the light exit area of ​​the light emitted by the light transmissive element 200, and the cooling element 400 is in contact with the light incident surface 210 of the light transmissive element 200, so that the light exit area of ​​the light transmissive element 200 is increased, and the effective area contacting the skin is also increased, thereby improving the cooling effect and the light exit efficiency, and improving the skin care efficiency. In addition, when the light emitting effect and the cooling effect are required to be the same, compared with the prior art in which the cooling element 400 is arranged on the side of the light transparent element 200, the thickness of the light transparent element 200 is thicker, resulting in a loss of cooling capacity. In the present application, the cooling element 400 is arranged on the light incident surface 210 of the light transparent element 200, so that the thickness of the light transparent element can be made thinner. Then, the smaller the area of ​​the light transparent element 200 that exchanges heat with the air in the thickness direction thereof, the smaller the cooling capacity loss.

[0035] Reference Figure 3 and Figure 4 The light incident surface 210 includes a light incident area 211 and a contact area 212. The light incident area 211 is, for example, Figure 3 In the area surrounded by the dotted line shown, the light-entering area 211 is located at the center of the light-entering surface 210, and the contact area 212 is distributed around the light-entering area 211. In other embodiments, the distribution of the contact area 212 and the light-entering area 211 can be adjusted according to the actual design of the product, which is not limited here. The light-entering area 211 is used to guide the light generated by the light source assembly 100 into the light-transmitting member 200, and the cooling member 400 contacts the contact area 212.

[0036] In this embodiment, the light source assembly 100 generates light, which enters the light-transmitting member 200 through the light-entering area 211. The light-entering area 211 is located at the center of the light-entering surface 210, which is conducive to accurately introducing light. The cooling element 400 is arranged in the contact area 212 and contacts the contact area 212 to ensure that the cooling element 400 effectively provides cooling capacity to the light-transmitting member 200, thereby reducing the pain and burning sensation during skin treatment. The cooling element 400 is arranged on the contact area 212 of the light-transmitting member 200 and contacts the contact area 212. The cooling element 400 will not block the light-entering surface 210 of the light-transmitting member 200, so that the light-emitting area of ​​the light generated by the light source assembly 100 when it is emitted from the light-emitting surface of the light-transmitting member 200 will not be affected by the cooling element 400. Therefore, the cooling area and the light-emitting surface 220 of the light-transmitting member 200 can be increased, thereby improving the cooling effect and light-emitting efficiency, so that there is no need to increase the thickness of the light-transmitting member 200. In this embodiment, the light-transmitting member 200 is, for example, a sapphire crystal. The thinner the light-transmitting member 200 is, the more sapphire wafers can be cut. Therefore, the thinner the light-transmitting member 200 is, the lower the cost of using the light-transmitting member 200 is. In other embodiments, the light-transmitting member 200 is, for example, quartz glass or K9 glass. Any light-transmitting member that can reduce the burning sensation caused by the light emitted by the light source assembly 100 on the skin is acceptable, and the specifics are not limited here.

[0037] Specifically, the distance from the light incident surface 210 to the light emitting surface 220 is 1-10 mm. By limiting the distance range from the light incident surface 210 to the light emitting surface 220, this embodiment can ensure that when light is transmitted from the light incident surface 210 of the light-transmitting member 200 to the light emitting surface 220, it passes through a shorter distance, thereby reducing energy loss and light diffusion, improving light extraction efficiency and cooling effect, allowing more light to accurately irradiate the skin, and achieving better therapeutic effects. In one embodiment, the distance from the light incident surface 210 to the light emitting surface 220 is 1 mm. In another embodiment, the distance from the light incident surface 210 to the light emitting surface 220 is 5 mm, and in yet another embodiment, the distance from the light incident surface 210 to the light emitting surface 220 is 10 mm. Preferably, the distance from the light incident surface 210 to the light emitting surface 220 is 1.5-5 mm. This embodiment can control the focusing degree of light and the heat conduction distance by limiting the distance range from the light incident surface 210 to the light emitting surface 220, thereby controlling the transfer of heat between the light-transmitting element 200 and the skin, avoiding excessive heat transfer to the skin, reducing pain, and improving comfort and safety, so as to ensure that the skin treatment device 1 has a good light emitting effect and a cooling effect while having a low cost.

[0038] Reference Figure 5 and Figure 6The skin treatment device 1 further includes, for example, a support bracket 600, which is, for example, disposed on a side of the light-transmitting member 200 close to the light source assembly 100, the support bracket 600 is connected to the light-transmitting member 200 and in contact with the contact area 212, the support bracket 600 is provided with an installation space 620, and the refrigeration member 400 is provided on the installation space 620. The installation space 620 is, for example, provided on the side of the support bracket 600, and the installation space 620 is, for example, a space formed by an inward depression on the side of the support bracket 600. The support bracket 600 provides additional support and protection to prevent the light-transmitting member 200 and the refrigeration member 400 and other components mounted thereon from being impacted or damaged by the outside world, thereby improving the stability and durability of the device, extending the service life, and achieving the excellent cooling effect and structural stability of the skin treatment device 1.

[0039] Reference Figure 6 , a light-entering hole 610 is provided on the support bracket 600, and a mounting space 620 is provided adjacent to the light-entering hole 610, and the cooling element 400 is embedded in the mounting space 620 and exposed on the surface of the support bracket 600. In this embodiment, by providing the light-entering hole 610, light can pass through the support bracket 600 through the light-entering hole 610 and enter the light-transmitting element 200, thereby achieving accurate light conduction. The cooling element 400 is embedded in the mounting space 620 of the support bracket 600 and exposed on the surface of the support bracket 600. The cooling element 400 exposed on the surface of the support bracket 600 can increase the heat dissipation effect and maintain the working temperature of the cooling element 400. In this way, when the cooling element 400 is working, the light-transmitting element 200 can be cooled more effectively, the cooling structure is optimized, the cooling effect of the skin treatment device 1 is improved, the skin temperature is reduced, and the pain is reduced.

[0040] Further, there are multiple cooling elements 400, and there are multiple installation spaces 620. The multiple cooling elements 400 are arranged in a one-to-one correspondence with the multiple installation spaces 620, wherein the multiple installation spaces 620 are distributed on the side of the support bracket 600, and the multiple cooling elements 400 are arranged around the light entrance hole 610 and contact the contact area 212. And by arranging the multiple cooling elements 400 in a one-to-one correspondence with the multiple installation spaces 620, the light-transmitting element 200 is cooled by arranging the multiple cooling elements 400. The multiple installation spaces 620 are distributed on the side of the support bracket 600. In this embodiment, the multiple installation spaces 620 are distributed on the side of the support bracket, for example. When there are two installation spaces 620, such as Figure 8As shown, it can be arranged on the opposite left and right sides of the support bracket 600. When there are three installation spaces 620, two of the installation spaces 620 are arranged on the opposite left and right sides of the support bracket 600, and the remaining installation space 620 can be arranged on the upper side or the lower side of the support bracket 600. The installation space 620 is used to provide an installation position for the refrigeration component 400, so that the refrigeration component 400 can fully contact the area that needs to be cooled, thereby effectively delivering the cooling effect. Multiple installation spaces 620 are distributed on the side of the support bracket 600, which can reasonably utilize the space, avoid occupying additional installation positions, and improve the space utilization and installation flexibility inside the device. In addition, the refrigeration component 400 is arranged around the light-entering through hole 610, which can realize cooling of the area near the light-entering through hole 610, effectively reduce the temperature, and improve the working efficiency of the system in a high temperature environment.

[0041] Reference Figure 5 and Figure 6 The skin treatment device 1 also includes a wire space 630, which is connected to the installation space 620, for example, so that the structure of the skin treatment device 1 is more compact, which is conducive to reducing the volume. The refrigeration element 400 is also provided with a first wire 410 and a second wire 420, which are arranged through the wire space 630. One of the first wire 410 and the second wire 420 is connected to the positive pole of the power supply, and the other of the first wire 410 and the second wire 420 is connected to the negative pole of the power supply.

The refrigeration element 400 is provided with a first wire 410 and a second wire 420, which are arranged through the wire space 630. In this embodiment, the first wire 410 and the second wire 420 are located at the same end of the refrigeration element 400, for example, which is conducive to reducing the winding distance, making the structure of the skin treatment device 1 more compact.

In this embodiment, the temperature equalizing plate may include multiple, multiple temperature equalizing plates are arranged at intervals, so that the heat transferred to the temperature equalizing plate is dissipated in a divergent manner. The mounting bracket 500 is arranged on the side close to the light source assembly 100, and the light source assembly 100 is arranged in the mounting bracket 500, which can ensure the stability of the position of the light source assembly 100, and can reduce the displacement or damage of the light position caused by external vibration or collision, and ensure safe use.

[0045] Reference Fig. 9 The skin treatment device 1, for example, also includes an auxiliary light-emitting component 170, which is, for example, arranged between the light source assembly 100 and the light-transmitting component 200. During the operation of the skin treatment device 1, the light generated by the light source assembly 100 first passes through the auxiliary light-emitting component 170, and then is emitted through the light-transmitting component 200. The auxiliary light-emitting component 170 can achieve the effect of uniform light by adjusting and evenly distributing the light, so as to ensure that the light generated by the light source assembly 100 is evenly distributed on the light-transmitting component 200, avoid the problem of excessive or low local brightness, and provide a more uniform and consistent lighting effect. In addition, by setting the auxiliary light-emitting component 170, the light source assembly 100 and the internal stacking structure can be shielded to prevent the user from seeing the internal stacking structure through the light-transmitting component 200, thereby increasing the aesthetic effect of the skin treatment device 1 and improving the user experience.

[0046] Reference Figure 5 , Figure 6 and Fig.10The skin treatment device 1 also includes a heat-conducting connector 180, such as heat-conducting silicone grease, etc. The heat-conducting connector 180 is, for example, disposed between the light-transmitting member 200 and the cooling member 400, and the heat-conducting connector 180 contacts the light-incident surface 210, and the heat-conducting connector 180 is thermally connected to the light-transmitting member 200 and the cooling member 400. When the light source assembly 100 generates heat, the heat-conducting connector 180 contacts the light-transmitting member 200 and the cooling member 400, and quickly transfers the heat to the cooling member 400 through heat conduction, providing an efficient heat conduction channel, so that the heat can be quickly transferred to the cooling member 400, and the heat is effectively dissipated. By providing the heat-conducting connector 180, the light-transmitting member 200 maintains a uniform temperature distribution, ensuring uniform light output, and the heat-conducting connector 180 effectively controls the temperature of the light source assembly 100, preventing temperature fluctuations and instability caused by overheating, and maintaining stable operation of the device.
