Description

Technical Field

[0001] The utility model relates to the technical field of hair removal devices, and more specifically to an intense pulsed light hair removal device. Background Art

[0002] In order to eliminate body hair, people use various methods for hair removal. The most common method is light hair removal, which is to irradiate the skin with intense pulsed light. The pigment in the hair follicles of the skin absorbs the light energy and generates heat, which destroys the function of the hair follicles and causes the hair to fall off. The hair will no longer grow, thus achieving the purpose of long-term hair removal.

[0003] At present, general hair removal devices use intense pulse light sources as hair removal light sources. Their light output structure usually includes a reflector and a lamp tube that releases the intense pulse light source. The lamp tube is located inside the reflector. When in use, part of the intense pulse light released by the lamp tube is directly emitted from the reflector, and the remaining intense pulse light source is reflected by the reflector and then emitted, acting together on the designated skin area.

[0004] However, after the light emitted by the lamp tube is initially reflected by the reflector, its light distribution often tends to show a phenomenon of excessive local light concentration. This light distribution condition may affect the irradiation effect of the intense pulse light source on the designated skin area during the use of the hair removal device, resulting in poor hair removal effect. Excessively concentrated light may also cause skin burns.

[0005] In view of this, it is indeed necessary to provide a technical solution to the above problems. Utility Model Content

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] An intense pulsed light hair removal device is constructed, comprising a light source and a reflector. Light emitted by the light source is reflected by the reflector to form a high-density area with dense light and a low-density area with relatively sparse light at the light outlet of the reflector. A plurality of light guide plates are arranged at intervals at the light outlet, and the light guide plates guide part of the light in the high-density area to the low-density area to disperse the light in the high-density area.

[0009] As an improvement to the intense pulsed light hair removal device, the light guide plates have the same height and their ends are aligned.

[0010] As an improvement to the intense pulsed light hair removal device, when the light distribution density toward the light outlet is high in the middle and low on both sides, the upper ends of several light guide plates are aligned, and the height gradually decreases from the middle to both sides, so that the light is distributed from the center to both sides.

[0011] As an improvement to the intense pulsed light hair removal device, when the light distribution density toward the light outlet is low in the middle and high on both sides, the upper ends of several light guide plates are aligned, and the height gradually decreases from both sides toward the middle, so that the light is distributed from both sides to the center.

[0012] As an improvement to the intense pulsed light hair removal device, when the light distribution density toward the light outlet is high in the middle and at both ends, the upper ends of several light guide plates are aligned, and the heights of the light guide plates at the two ends and the middle are the same, and the heights of the light guide plates gradually decrease from the ends to the middle.

[0013] As an improvement to the intense pulsed light hair removal device, several of the light guide plates have the same height, and at least part of the light guide plates on both sides are gradually inclined outward, which is used to guide part of the light in the high-density area toward the low-density area. At the same time, at least part of the light that is reflected toward the light outlet and inclined inward can be guided by the light guide plate and reflected outward.

[0014] As an improvement to the intense pulsed light hair removal device, when the high-density areas of the light distribution directed to the light outlet are located at multiple positions on both sides, several light guide plates are distributed to form a first light guide plate and multiple reflective groups symmetrically arranged with respect to the first light guide plate. The multiple light guide plates of the reflective groups have different lengths, wherein the upper ends of the multiple light guide plates of the same reflective group are located at the same horizontal position, and the horizontal position of the lower ends gradually decreases in the direction approaching the first light guide plate.

[0015] As an improvement to the intense pulsed light hair removal device, the reflective groups located on the same side of the first light guide plate have at least some light guide plates of different lengths.

[0016] As an improvement of the intense pulsed light hair removal device, at least part of the light guide plate is provided with a parabolic reflective portion to emit the light in parallel.

[0017] As an improvement of the intense pulsed light hair removal device, a filter and a mounting bracket for mounting a plurality of the light guide plates are provided on the top of the reflector. An adjustment mechanism for adjusting the spacing between the light guide plates is provided on the mounting bracket. The bottom of the reflector is set to a parabolic arc shape.

[0018] The beneficial effects of the present invention are:

[0019] This intense pulsed light hair removal device is provided with a number of light guide plates arranged at intervals. The light guide plates can be set to different heights, or to have some of the same heights, or to have all of the same heights, for adaptation according to the different density distribution conditions of the light reflected by the reflector, thereby guiding part of the light in the high-density area toward the low-density area, avoiding the phenomenon of local excessive concentration of the light emitted from the light outlet, thereby improving the uniformity of light irradiating the target area, thereby improving the hair removal effect of the hair removal device; at the same time, the uniform light distribution can also reduce skin problems that may be caused by uneven light, such as burns or incomplete hair removal, and also improve the user's hair removal experience.

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] It should be noted that in Figures 7 to 9 In the figure, the blue one is the normal, the black one is the light emitted by the light source, and the red one is the light guide plate. Figures 10 to 14 In the figure, the blue is the normal, the black is the initial light, the red is the first reflected light, the purple is the second reflected light, the green is the third reflected light, the yellow is the fourth reflected light, and the cyan is the fifth reflected light.

[0039] like Figure 1 and Figure 15 As shown, an intense pulsed light hair removal device includes a light source 2 and a reflector 1. After the light emitted by the light source 2 is reflected by the reflector 1, a high-density area with dense light and a low-density area with relatively sparse light are formed at the light outlet of the reflector 1; a plurality of light guide plates 4 are arranged at intervals at the light outlet to guide part of the light in the high-density area to the low-density area to disperse the light in the high-density area.

[0040] Specifically, the light source 2 is a xenon lamp. The light outlet is located above the reflector 1. After the light source 2 is turned on, part of the emitted light is emitted directly toward the light outlet, and the remaining light is reflected once or multiple times by the reflective surface inside the reflector 1 and then emitted from the light outlet. Several light guide plates 4 are arranged at intervals, and according to the different density distribution conditions of the light reflected by the reflector 1, the light guide plates 4 can be set to different heights, or partially the same height, or all the same heights for adaptation, thereby guiding part of the light in the high-density area toward the low-density area. This improves the uniformity of light irradiating the target area, thereby improving the hair removal effect of the hair removal device. At the same time, the uniform light distribution can also reduce skin problems that may be caused by uneven light, such as burns or incomplete hair removal, and also improves the user's hair removal experience.

[0041] It should be noted that the number of light guide plates 4 is 13, and the number of light guide plates 4 can also be adjusted according to needs, including but not limited to: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 15 or 16. On the basis of setting up 13 light guide plates 4, if more light guide plates 4 are added, the light can be guided and distributed more finely, which helps to further reduce the excessive concentration of light in local areas and reduce the scattering and divergence of light. If the number of light guide plates 4 is reduced, the light can be guided only in the area where the local light is relatively concentrated, and the light can be directed in other directions to disperse the light in the high-density area; by setting up a small number of light guide plates 4, the purpose of improving the uniformity of light emitted from the light outlet is achieved.

[0042] In some embodiments of the present application, several light guide plates 4 have the same height and their ends are aligned. Specifically, in this case, the light guide plates 4 are designed to have the same height and aligned ends. When the light distribution at the light outlet is already relatively uniform, by maintaining the same height and aligned ends of the light guide plates 4, the light is evenly emitted from the intervals between the light guide plates 4, maintaining the uniform distribution of light, and further improving the uniformity of the light emitted from the light outlet in the target area and the hair removal effect.

[0043] The determination of uniform light distribution at the light outlet can be performed, for example (including but not limited to): density values ​​are randomly taken at multiple locations in the high-density area, with the maximum density value being the first value; density values ​​are randomly taken at multiple locations in the low-density area, with the minimum density value being the second value. When the density difference between the first value and the second value is less than 5% of the first value, the distribution of the emitted light at the light outlet is relatively uniform. By sampling and comparing the first value and the second value, it is determined that the density difference between the high-density area and the low-density area of ​​the light outlet is less than 5% of the first value. Regarding the acquisition of the first value and the second value, multiple sampling points are performed at different locations in the high-density area and the low-density area of ​​the light outlet using a photometer or optical density measuring device; the light intensity readings at these sampling points can be used to calculate the density difference between each point. The density value is actually the light intensity value at different locations of the light outlet, thereby determining the first value and the second value. In other embodiments, the density difference between the first value and the second value (i.e., 5%) can be set according to specific actual needs.

[0044] It should be noted that the bottom of the reflector 1 is the lower cover 101, and the structure of the intense pulsed light hair removal device forming a light distribution density difference of less than 5% includes but is not limited to: 1. Figure 7 As shown, the reflector 1 is semicircular, and the axis of the lamp is aligned with the center of the reflector 1, and Figure 7 Schematic diagram of light distribution before uniform light;

[0045] Figure 8 Schematic diagram of light distribution after light uniformity. Figure 12 As shown, the reflector 1 is polygonal, and the axis of the lamp tube is aligned with the center of the lower cover portion 101 .

[0046] In some embodiments of the present application, Figure 2 As shown, when the light distribution density toward the light outlet is high in the middle and low on both sides, the upper ends of several light guide plates 4 are aligned, and the height gradually decreases from the middle to the sides, so that the light is evenly distributed from the center to the two sides. Specifically, when the light density toward the light outlet is high in the middle and low on both sides, under this light density distribution, several light guide plates 4 are set to be aligned at the upper ends, but the height gradually decreases from the middle to the two sides, so that the light guide plates 4 can guide and redistribute the light. When the high-density light toward the middle of the light outlet encounters the light guide plates 4 that gradually decrease from the middle to the two sides, it is reflected by the light guide plates 4 and guided to the low-density areas on both sides to be emitted, making the light more uniform at the light outlet, significantly improving the original light distribution that was high in the middle and low on both sides, so that the light can be more evenly irradiated to the target area, ensuring the uniformity of energy release when the hair removal device is in use.

[0047] It should be noted that if Figure 10As shown, the bottom of the reflector 1 is the lower cover part 101, and the intense pulsed light hair removal device forms a light distribution density structure with high density in the middle and low density on both sides, including but not limited to: the reflector 1 is semicircular, and the axis of the lamp tube is lower than the center of the lower cover part 101.

[0048] In some embodiments of the present application, Figure 5 As shown, when the light distribution density toward the light outlet is low in the middle and high on both sides, the upper ends of several light guide plates 4 are aligned, and the height gradually decreases from both sides toward the middle, so that the light is evenly distributed from both sides to the center. Specifically, when the light density toward the light outlet is low in the middle and high on both sides, several light guide plates 4 are set to an arrangement structure in which the upper ends are aligned and the height gradually decreases from both sides toward the middle. The high-density light on both sides is guided toward the middle by the light guide plates 4 with gradually decreasing heights. Specifically, the light is reflected by the surface of the light guide plates 4, so that the light originally diverging to both sides is redirected to the central area, thereby achieving the effect of light homogenization. The uniform distribution of light from both sides to the center is achieved, which significantly improves the uniformity of light irradiation to the target area. Secondly, the uniform light distribution enables the hair removal device to act more effectively on the target hair, thereby improving the hair removal effect.

[0049] In some embodiments of the present application, Figure 3 As shown, when the light distribution density toward the light outlet is high in the middle and at both ends, the upper ends of several light guide plates 4 are aligned, and the height of the light guide plates 4 at both ends and in the middle is the same, and the height of the light guide plates 4 from the ends to the middle is gradually reduced. Specifically, when the light density toward the light outlet is high in the middle and at both ends, the light guide plates 4 are arranged to be aligned at the upper ends, and the height of the light guide plates 4 at both ends and in the middle is kept consistent, but the light guide plates 4 from the ends to the middle are arranged to be gradually reduced in height. Since the light is more concentrated in the middle and at both ends, the structural design of the light guide plates 4 can effectively guide the light concentrated at both ends and in the middle of the light outlet toward the low-density area, and the light guide plate 4 in the middle position can not only disperse the light concentrated in the middle, but also prevent the light guide plates 4 on both sides from concentrating the light to the middle. Specifically, the light guide plate 4 at a higher position will reflect more light to the light guide plate 4 at a lower position, and achieve uniform distribution of light through multiple reflections and scattering. Through the above arrangement of the light guide plates 4 , the light originally concentrated in the middle and at both ends is effectively dispersed to the entire light outlet area, making the light distribution more uniform.

[0050] It should be noted that if Figure 11 As shown, the bottom of the reflector 1 is the lower cover part 101, and the intense pulsed light hair removal device forms a structure in which the light distribution density is high in the middle and at both ends, including but not limited to: the reflector 1 is semicircular, and the axis of the lamp tube is higher than the center of the lower cover part 101.

[0051] In some embodiments of the present application, Figure 6As shown, several light guide plates 4 have the same height, and the light guide plates 4 on both sides are gradually inclined outward, which are used to guide part of the light in the high-density area toward the low-density area. At the same time, part of the light that is reflected toward the light outlet and inclined inward can be guided outward through the light guide plate 4.

[0052] Specifically, several light guide plates 4 of the same height are arranged such that the light guide plates 4 on both sides are gradually tilted outward. When the light distribution is already relatively uniform, by maintaining the same height and aligning the ends of the light guide plates 4, light is evenly emitted from the spaces between the light guide plates 4, maintaining a uniform light distribution. Furthermore, the tilted light guide plates 4 can re-reflect a portion of the light that was originally tilted inward and directed toward the light outlet, directing it outward at an angle, thereby achieving a more evenly diffused light distribution and further improving the uniformity of the light distribution. By adjusting the angle and tilt of the light guide plates 4, excessive concentration of light in a particular area can be effectively avoided.

[0053] Increasing the tilt angle of the light guide plate can promote even distribution of light at the light outlet, reducing localized over-concentration of light, and thus improving hair removal effectiveness. However, excessively large tilt angles can also cause excessive light dispersion, reducing the energy density in the target area. Therefore, it is necessary to find the optimal tilt angle balance in practical applications. Reducing the tilt angle of the light guide plate is intended to more precisely direct light to the target area, especially when treating small or specifically shaped target areas. A smaller tilt angle helps maintain energy density in the target area and avoids energy loss due to excessive light diffusion.

[0054] It should be noted that if Figure 14 As shown, the bottom of the reflector 1 is the lower cover part 101, and the intense pulsed light hair removal device forms a structure in which part of the light is reflected and emitted toward the light outlet and is inclined inward, including but not limited to: the reflector 1 is polygonal, and the axis of the lamp tube is higher than the center point of the lower cover part 101.

[0055] In some embodiments of the present application, Figure 4 As shown, when the high-density areas of the light distribution toward the light outlet are located at multiple positions on both sides, a plurality of light guide plates 4 are distributed to form a first light guide plate 4 and a plurality of reflective groups symmetrically arranged with respect to the first light guide plate 4. The plurality of light guide plates 4 in the reflective groups have different lengths. Among them, the upper ends of the plurality of light guide plates 4 in the same reflective group are located at the same horizontal position, and the horizontal position of the lower ends gradually decreases in the direction approaching the first light guide plate 4.

[0056] Specifically, when high-density areas of light distribution toward the light outlet are located at two locations on either side, there are four high-density areas, corresponding to the four reflective groups. Several light guide plates 4 are arranged in a structure consisting of a first light guide plate 4 and multiple reflective groups symmetrically arranged around the first light guide plate 4. Each reflective group consists of three light guide plates 4 of varying lengths. Vertically, these three light guide plates 4 have varying heights to accommodate light density at different locations. The upper ends of the three light guide plates 4 in the same reflective group are positioned at the same horizontal position, ensuring consistency in the light ultimately reflected from the light outlet. The lower ends of the three light guide plates 4 gradually decrease in horizontal position toward the first light guide plate 4, helping to guide light from high-density areas to low-density areas. Multiple reflective groups are arranged symmetrically around the first light guide plate 4, ensuring uniform and symmetrical light distribution. By adjusting the arrangement of the light guide plates 4 of varying heights, light can be effectively diffused from multiple high-density areas to low-density areas.

[0057] It should be noted that if Figure 13 As shown, the bottom of the reflector 1 is the lower cover part 101. The structure of the intense pulsed light hair removal device that concentrates the light at multiple positions on both sides includes but is not limited to: the reflector 1 is polygonal, and the axis of the lamp tube is lower than the center point of the lower cover part 101.

[0058] In some embodiments of the present application, the reflective groups located on the same side of the first light guide plate 4, wherein at least some of the light guide plates 4 have different lengths. Specifically, in an intense pulsed light hair removal device, after the light emitted by the light source 2 is initially reflected by the reflector 1, its distribution may present different density patterns, including but not limited to high in the middle and low on both sides, low in the middle and high on both sides, etc. In particular, when the high-density areas of light distribution are located at multiple positions on both sides of the light outlet of the reflector 1, more precise adjustment is required. Since the high-density areas at different positions have different light distributions, the reflective groups located on the same side of the first light guide plate 4 can adjust the lengths of some of the light guide plates 4 therein to match the light distribution conditions of the corresponding high-density areas, thereby achieving precise guidance of light in high-density areas at different positions.

[0059] In some embodiments of the present application, the bottom of the reflector 1 is configured to have a parabolic curvature. Specifically, with the parabolic bottom design of the reflector 1, when the light source 2 is located at the focal point of the parabola, light emitted from the focal point, after reflection from the parabola, forms parallel light beams, which helps reduce light scattering and improves light utilization and directionality. Through the focusing and parallelization effect of the parabola, the light emitted by the light source 2 can be more evenly illuminated to the target area, reducing uneven light distribution.

[0060] In some embodiments of the present application, a filter 3 and a mounting bracket 5 for mounting a plurality of light guide plates 4 are located on the top of the reflector 1. The mounting bracket 5 is equipped with an adjustment mechanism for adjusting the spacing between the plurality of light guide plates 4. Specifically, the filter 3, located on the top of the reflector 1, is primarily used to filter out non-target wavelengths of light emitted by the light source 2, ensuring that only light of specific wavelengths (such as those required for intense pulsed light hair removal) can pass through, thereby improving light purity and hair removal effectiveness. The filter 3 can reduce potential damage to the skin while enhancing hair removal effectiveness. The mounting bracket 5 is used to secure and support the light guide plates 4, ensuring that they are stably positioned at the light outlet and allowing for adjustment as needed. The mounting bracket 5 is designed with an adjustment mechanism for adjusting the spacing between the light guide plates 4, allowing the user or technician to manually or automatically adjust the spacing between the light guide plates 4 based on the specific light distribution. By changing the relative position of the light guide plates 4, the reflection path and distribution of light after passing through the light guide plates 4 are altered, thereby optimizing light distribution and reducing skin problems that may be caused by uneven light.

[0061] In other embodiments, Figure 9 As shown, the light guide plate 4 is provided with a parabolic reflective portion 401 to emit light in parallel. Specifically, the operating principle of the parabolic reflective portion 401 provided on the light guide plate 4 is mainly based on the optical properties of a parabola. When light strikes the parabolic reflective portion 401, it is reflected and redirected, so that light incident from all directions is emitted in approximately parallel directions after reflection. This not only achieves the parallelization of light, reduces light scattering and divergence, improves light utilization, but also ensures uniform light distribution.

[0062] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.
