At the same time, since the beauty device cannot obtain the information about the hair on the user's face, it is impossible to adjust the corresponding light-emitting range and light-emitting parameters. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a hair removal device that can effectively obtain the distribution position and distribution condition of hairs in the acting area, and then can adaptively adjust the light-emitting range and light-emitting parameters in view of the above-mentioned prior art.

[0017] Figure 2 It is a cross-sectional view of the hair remover in the embodiment of the present utility model. Detailed Description of the Embodiment

[0018] The present utility model will be further described in detail below with reference to the embodiments of the drawings.

[0019] As Figure 1 and Figure 2 shown, the hair remover in this embodiment includes a housing 1, a light source assembly 2, a light-transmitting plate 3, an information collector 4, and an adjusting mechanism 5.

[0020] The housing 1 has a light outlet, and the light source assembly 2 is arranged facing the light outlet, so that light can be emitted from the light outlet and act on the user's skin. The light source assembly 2 can adopt various structural forms of light source assemblies 2 used in existing hair removal devices. In this embodiment, the light source assembly 2 includes a pulsed lamp tube 21 arranged facing the light outlet, and a light acting plate 22 with an arc-shaped cross-section arranged behind the pulsed lamp tube 21. Different materials of the light acting plate 22 are correspondingly set according to the required light processing effect. To ensure the safety of use, a light-transmitting plate 3 is covered and installed on the light outlet of the housing 1 in front of the light source assembly 2, so that the user can attach the light-transmitting plate 3 to the skin for use.

[0021] The information collector 4 is used to collect hair information on the user's skin. The hair information includes hair distribution position information, hair density information, etc. In this embodiment, the information collector 4 adopts an image collector. The skin image in the area of the light outlet is obtained through the image collector, and then the hair distribution position and distribution density on the skin are obtained through existing image processing algorithms. To better achieve the zonal collection of hair information on the skin, there are two information collectors 4, one of which is arranged at the center of half of the light outlet area, and the other is arranged at the center of the other half of the light outlet area.

[0022] The adjustment mechanism 5 is arranged on one side of the light-transmitting plate 3, and the adjustment mechanism 5 is used to adjust the light-emitting area of the light outlet. To prevent the adjustment mechanism 5 from affecting the collection of facial hair information by the information collector 4, the information collector 4 is embedded in the light-transmitting plate 3, and the adjustment mechanism 5 is arranged at the rear of the light-transmitting plate 3. By adjusting the light-emitting area, not only can the irradiation position of the emitted light be adjusted, but also the adjustment of the emitted light energy can be achieved.

[0023] Specifically, the adjustment mechanism 5 in this embodiment includes a driving module and a baffle 51 connected to the driving end of the driving module. The baffle 51 can move relative to the light outlet based on the driving of the driving module. There are two baffles 51 in this embodiment, and each baffle 51 is equipped with a driving module. The driving module includes a motor 52 and a driving rod 53 connected to the driving end of the motor 52, and the baffle 51 is connected to the driving rod 53. By driving the driving rod 53 by the motor 52, the driving rod 53 drives the two baffles 51 to open and close relative to the light outlet. The area of the light outlet blocked by the baffle 51 cannot emit light, thereby realizing the adjustment of the light-emitting area of the light outlet. Briefly, the driving rod 53 in this embodiment extends along the moving direction of the baffle 51 and is threadedly connected to the baffle 51. As the motor 52 drives the driving rod 53 to rotate, the baffle 51 moves back and forth along the axial direction of the driving rod 53.

[0024] The light-acting plate 22 cooperates with the baffle 51 to control the area and energy of the emitted light. In this embodiment, two types of light-acting plates 22 and two types of baffles 51 are provided for matching to achieve different effects. Of course, the light-acting plate 22 and the baffle 51 are not limited to these two combination methods, and their materials can be specifically determined according to more light requirements.

[0025] In this embodiment, in one case, the light-acting plate 22 is a condenser plate with a condensing effect, and the baffle 51 is a reflector with a light-reflecting coating on the side facing the condenser plate. Based on the characteristics of the light-acting plate 22 and the baffle 51, the light energy emitted by the pulsed lamp tube 21 can be fully utilized. The light emitted by the pulsed lamp tube 21 and irradiated on the condenser plate is more concentrated and emitted from the middle of the light outlet after reflection and condensation, while the pulsed light irradiated on the baffle 51 is reflected to the condenser plate by the reflection of the baffle 51 and then emitted from the light outlet through the emission of the condenser plate. In this way, the light energy emitted by the pulsed lamp tube 21 can be fully utilized to ensure the light energy of the emitted light. During operation, only lower operating parameters are required to achieve a better light energy effect, making it more energy-efficient.

[0026] In another case, the light-acting plate 22 is a light-absorbing plate capable of absorbing light, and the baffle 51 is a light-shielding plate with a light-absorbing coating on the side facing the condenser plate. Based on the characteristics of the light-acting plate 22 and the baffle 51, the excess pulsed light can be absorbed. The pulsed light irradiated on the light-absorbing plate by the pulsed lamp tube 21 is absorbed by the light-absorbing plate and thus no longer emitted from the light outlet, and the pulsed light irradiated on the baffle 51 is also absorbed due to the effect of the light-absorbing layer. This structure of the hair removal device can effectively reduce the energy of the emitted pulsed light, avoid excessive energy of the pulsed tube, and is particularly suitable for the case where the required pulsed light energy is lower than the set minimum power condition, and can be used for sensitive skin and delicate skin areas.

[0027] A control circuit board electrically connected to the light source assembly 2, the information collector 4, and the adjustment mechanism 5 is usually further provided in the housing 1. The light source assembly 2, the information collector 4, and the adjustment mechanism 5 operate based on the control of the control circuit board.

[0028] In the hair remover of the present utility model, various information such as the hair distribution area and hair distribution density on the user's skin can be collected by the information collector 4. Then, the adjusting mechanism 5 can drive the baffle 51 to move relative to the light outlet based on this information, so as to adjust the light output area and light output range of the light outlet, and control the light output area to match the hair distribution area. In this way, it can effectively avoid the part without hair being irradiated by light and heated, and improve the comfort during the hair removal process. In addition, by collecting the hair distribution density information, the working parameters of the light source assembly 2 can be adjusted correspondingly, so as to achieve one-time hair removal treatment, avoid problems such as multiple adjustments of working parameters and long working hours, and avoid skin damage or incomplete hair removal caused by the mismatch between the working parameters and the hair density at the acting position.

However, these terms are used here only for the purpose of convenient description and are determined based on the exemplary orientations shown in the drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions should be regarded as illustrative rather than restrictive. For example, "upper" and "lower" are not necessarily limited to the directions opposite to or consistent with the direction of gravity.
