[0038] A phototherapy beauty device is a type of beauty device that performs phototherapy by emitting light to illuminate the user's target skin area. Existing phototherapy beauty devices generally include a light-emitting component and a light-transmitting component. The light-emitting component is arranged inside the body of the phototherapy beauty device, and the light-transmitting component is arranged on the shell of the phototherapy beauty device. The light emitted by the light-emitting component illuminates the target skin area of ​​the human body through the light-transmitting component, and continuously illuminates the target skin area to achieve beauty effects such as whitening and freckle removal. However, in existing phototherapy beauty devices, since the connection between the light-transmitting component and the body of the beauty device is not tight and there is a connection gap, the light emitted by the light-emitting component is not only emitted after passing through the light-transmitting component, but also emitted from the connection gap, resulting in light leakage, thereby affecting the phototherapy effect of the phototherapy beauty device. At the same time, the existence of the connection gap also allows substances such as sebum, sweat and dust to enter the interior of the phototherapy beauty device, thereby affecting the service life of the beauty device.

[0039] In order to improve the tightness of the connection between the light-transmitting part of the beauty instrument and the body and eliminate the connection gap between the two, refer to Figure 1 The utility model proposes a beauty instrument, referring to Figure 2 and Figure 3 , the beauty instrument includes:

[0040] The housing 1 is provided with a light outlet 10 and a receiving cavity 11, and the light outlet 10 is connected to the receiving cavity 11;

[0041] The light-transmitting member 3 has one end disposed in the accommodating cavity 11 and the other end forming a light-emitting surface 3a, and the light-emitting surface 3a is exposed to the housing 1 through the light-emitting port 10;

[0042] The sealing member 2 is disposed in the accommodating cavity 11 and is used for sealing the gap between the light-transmitting member 3 and the housing 1 .

[0043] In this embodiment, the main structure of the beauty instrument of the present application includes a shell 1, a light-transmitting member 3 and a sealing member 2. The shell 1 is provided with a light outlet 10 and a receiving cavity 11, the light outlet 10 is connected to the receiving cavity 11, one end of the light-transmitting member 3 is arranged in the receiving cavity 11, and the other end of the light-transmitting member 3 forms a light-emitting surface 3a, and the light-emitting surface 3a is exposed to the shell 1 through the light outlet 10 on the shell 1. The sealing member 2 is arranged in the receiving cavity 11, connecting the light-transmitting member 3 and the shell 1, and the sealing member 2 is used to seal the gap between the light-transmitting member 3 and the shell 1, that is, the connection tightness between the light-transmitting member 3 and the shell 1 is improved by the sealing member 2. So that during the use of the beauty instrument of the present application, the light emitted by the light-emitting component passes through the light-transmitting member 3, and then is emitted from the light-emitting surface 3a of the light-transmitting member 3 through the light outlet 10 to the target skin area of ​​the human body outside the shell 1, and the light continuously irradiates the target skin area of ​​the human body to achieve a phototherapy effect. Since the seal 2 seals the gap between the light-transmitting component 3 and the shell 1, the light emitted by the light-emitting component will not leak out from the gap between the light-transmitting component 3 and the shell 1. Therefore, the beauty instrument of the present application reduces the probability of light leakage in the gap between the light-transmitting component and the shell in the phototherapy beauty instrument in the prior art by setting the seal 2, improves the utilization rate of light, and makes the phototherapy treatment effect of the beauty instrument of the present application better than that of the existing phototherapy beauty instrument in the prior art.

[0044] In some embodiments, the light-transmitting element 3 may be made of sapphire material, which has the following advantages:

[0045] First, the sapphire light-transmitting element 3 has good light-guiding properties and can fully utilize various visible lights emitted by the light source, allowing the lights to pass through the sapphire efficiently with little light loss.

[0046] Secondly, the light passing through the sapphire can form a soft and uniform light on the light-emitting surface, illuminating the skin surface.

[0047] Third, it has good durability. Sapphire has extremely high mechanical strength, corrosion resistance and high temperature resistance, which can make the light-transmitting element 3 work for a long time without performance degradation, thereby ensuring that the beauty instrument maintains a long service life.

[0048] Reference Figure 3 In some embodiments, the sealing member 2 provided in the embodiment of the utility model is an elastic sealing member, and the light-transmitting member 3 is interference-fitted with the sealing member 2 .

[0049] In this embodiment, the seal 2 is an elastic seal, that is, its material itself has the ability to deform elastically. When the light-transmitting member 3 is connected to the seal 2, the seal 2 undergoes elastic compression deformation, and the seal 2 can be closely attached to the surface of the light-transmitting member 3. Specifically, the light-transmitting member 3 and the seal 2 have an interference fit, and the interference fit means that the cross-sectional size of the light-transmitting member 3 is slightly larger than the inner diameter of the cross-sectional area of ​​the seal 2, so that when the two are connected, the seal 2 is in a compressed deformation state, so that the seal 2 generates a greater contact pressure on the light-transmitting member 3, thereby achieving a better sealing effect.

[0050] In this embodiment, the seal 2 is an elastic seal and has an interference fit design with the light-transmitting member 3, which can not only make the seal 2 and the light-transmitting member 3 automatically adapt to the assembly tolerance between the two to maintain elasticity and sealing performance, but also achieve a better sealing effect, effectively prevent light from leaking from the gap, and further, can adapt to slight relative displacement or vibration between the light-transmitting member 3 and the housing 1.

[0051] At the same time, the elastic seal will not cause damage to the connection between the light-transmitting member 3 and the housing 1. Its elastic deformation characteristics can also play a role in buffering and dust prevention. Compared with hard seals such as annular gaskets, the design of interference fit between the elastic seal and the light-transmitting member 3 in this embodiment has the advantages of good sealing, good elasticity, strong adaptability, etc., and is practical and efficient.

[0052] Reference Figures 3 to 5 In some embodiments, the light-transmitting member 3 proposed in the embodiments of the present utility model further includes a light incident surface 3b, the sealing member 2 includes a limiting cavity 21, a light incident hole 22 and a light emitting hole 20, the limiting cavity 21 connects the light incident hole 22 and the light emitting hole 20, the light emitting hole 20 is arranged corresponding to the light outlet 10, at least part of the light-transmitting member 3 is accommodated in the limiting cavity 21, the light emitting surface 3a is exposed to the light emitting hole 20, and the light-incoming surface 3b is exposed to the light incident hole 22.

[0053] In this embodiment, the limiting cavity 21 of the sealing member 2 accommodates at least a portion of the light-transmitting member 3, and the limiting cavity 21 plays a role in limiting and fixing the position and relative movement direction of the light-transmitting member 3. A light entrance hole 22 and a light exit hole 20 are provided on the sealing member 2, and the light entrance surface 3b of the light-transmitting member 3 is exposed in the light entrance hole 22, and the light exit surface 3a is exposed in the light exit hole 20.

[0054] When the light-emitting component of the beauty instrument emits light toward the light-transmitting member 3, the light first enters the limiting cavity 21 through the light entrance hole 22, then enters the interior of the light-transmitting member 3 through the light entrance surface 3b of the light-transmitting member 3, and finally the light is emitted from the light exit surface 3a of the light-transmitting member 3. After the emitted light is emitted to the outside of the limiting cavity 21 through the light exit hole 20, it continues to irradiate the target skin area of ​​the user through the light exit port 10 to achieve a phototherapy effect.

[0055] The arrangement of the limiting cavity 21, the light entrance hole 22 and the light exit hole 20 enables the sealing member 2 to be connected to the light-transmitting member 3 while the sealing member 2 does not block the light emitted by the light-emitting component of the beauty instrument to the light-transmitting member 3. That is, the sealing member 2 achieves a good sealing effect with the light-transmitting member 3 while not affecting the light-transmitting performance of the light-transmitting member 3 itself.

[0056] In summary, the design of the embodiment scheme enables the seal 2 to not only play a sealing role, but also enhance the positioning and installation functions of the light-transmitting component, and ensure the accuracy and stability of the optical path of the beauty instrument of the present application.

[0057] Reference Figures 3 to 5 In some embodiments, the sealing member 2 provided in the embodiment of the utility model includes a first surface 23 and a second surface 24 opposite to each other, the limiting cavity 21 is located between the first surface 23 and the second surface 24, the light exit hole 20 is arranged on the first surface 23, and the light entrance hole 22 is arranged on the second surface 24;

[0058] The light emitting surface 3 a of the light transmitting element 3 is convex, flush with, or concave to the first surface 23 , and / or the light incident surface 3 b of the light transmitting element 3 is convex, flush with, or concave to the second surface 24 .

[0059] In this embodiment, the sealing member 2 includes a first surface 23 and a second surface 24 that are opposite to each other, and a limiting cavity 21 is located between the first surface 23 and the second surface 24. The limiting cavity 21 is used to accommodate and fix the light-transmitting member 3. The light-emitting hole 20 is provided on the first surface 23, and the light-entering hole 22 is provided on the second surface 24. It can be understood that the light-emitting hole 20 is opposite to the light-entering hole 22. This design of the sealing member 2 avoiding the opening and the limiting cavity 21 on both sides can achieve a better isolation effect between the light-transmitting member 3 and the outside world relative to the light-transmitting member 3, reduce the possibility of light leakage and interference, and also have the characteristics of high light path collimation and light path stability, which is conducive to improving the lighting quality.

[0060] The light emitting surface 3a of the light transmitting member 3 is set to be convex, flush with or concave to the first surface 23, and / or the light incident surface 3b of the light transmitting member 3 is set to be convex, flush with or concave to the second surface 24. The different settings of the light emitting surface 3a and the light incident surface 3b can bring the following different beneficial effects:

[0061] First, it is beneficial to reduce light loss only when the light incident surface 3b is convex or flush with the second surface 24. When the light incident surface 3b is convex or flush with the second surface 24, the light does not need to pass through the light incident hole 22, which can reduce the reflection loss of the light, improve the light transmittance of the light-transmitting member 3, and help to fully utilize the light energy.

[0062] Secondly, only when the light emitting surface 3a is convex or flush with the first surface 23, it is beneficial to improve the distribution of the light. When the light emitting surface 3a is convex or flush with the first surface 23, the area of ​​the light emitting surface 3a exposed to the light emitting hole 20 is larger than that of the concave setting, which can improve the light intensity distribution of the light emitting surface 3a, achieve more uniform light irradiation, and avoid the phenomenon of focusing to a certain extent.

[0063] Thirdly, only when the light incident surface 3b is concave, it is helpful to reduce the surface reflection. The concave light incident surface 3b can eliminate the surface reflection and avoid affecting the incident utilization of light.

[0064] Fourthly, when the light-emitting surface 3a and the light-entering surface 3b are set to be concave, it is beneficial to improve the sealing effect. The concave light-emitting surface 3a and the light-entering surface 3b can make the limiting cavity 21 cover the side of the light-transmitting member 3, increase the sealing contact surface, improve the sealing effect, and reduce the light leakage loss. At the same time, a more stable support effect is achieved, the support function of the light-transmitting member 3 is enhanced, and the overall stability of the beauty instrument of the present application is improved.

[0065] The above-mentioned configuration of the light emitting surface 3a and the light incident surface 3b can bring positive improvements in terms of optical performance, practicality, stability, etc., and better play the lighting function of the beauty instrument. Those skilled in the art can design it according to actual needs.

[0066] Reference Figure 3 and Figure 4 In some embodiments, the light emitting surface 3 a of the light transmitting member 3 of the present utility model embodiment is protruding from the first surface 23 and connected to the light outlet 10 , and the light incident surface 3 b of the light transmitting member 3 is flush with or concave in the second surface 24 .

[0067] In this embodiment, the convex light emitting surface 3a can increase the light contact area between the light emitting surface 3a and the target skin area of ​​the user that needs light therapy, that is, the light projection range is wider and the irradiation is more uniform. It also reduces the reflection loss of light and has a higher light extraction efficiency.

[0068] The effect of the light incident surface 3b being flush or concave with the second surface 24 is that, when flush, the light-transmitting member 3 can receive incident light with a wider angle distribution, thereby improving the utilization rate of light. When concave, the anti-reflection effect of the concave surface of the sealing member 2 can also reduce the influence of surface reflection, improve the light incident performance, and make the light output more concentrated.

[0069] The light emitting surface 3a of the light-transmitting member 3 cooperates with the light outlet 10 of the housing 1 at the connection point, which can enhance the stable fixing effect of the housing 1 on the light-transmitting member 3 to ensure the accuracy and stability of the optical path.

[0070] In summary, this embodiment improves light utilization efficiency and light input and output performance, improves the lighting quality of the beauty instrument from different angles, and enhances the beauty effect by setting the light output surface 3a of the light transparent member 3 to protrude from the first surface 23 and the light input surface 3b of the light transparent member 3 to be flush with or recessed from the second surface 24.

[0071] Reference Figure 2 , Figure 3 and Figure 6 In some embodiments, the inner wall of the light outlet 10 proposed in the embodiment of the utility model is a wedge-shaped surface 101, and the light-transmitting member 3 includes a receiving portion 31 and a wedge-shaped portion 32, the receiving portion 31 is received in the limiting cavity 21, the wedge-shaped portion 32 extends out of the limiting cavity 21, and the wedge-shaped portion 32 is in contact with the wedge-shaped surface 101.

[0072] In this embodiment, the inner wall of the light outlet 10 is set as a wedge-shaped surface 101, and the light-transmitting member 3 is provided with a wedge-shaped portion 32 corresponding to the wedge-shaped surface 101. Through the fit between the wedge-shaped surface 101 and the wedge-shaped portion 32, the position self-locking effect of the wedge-shaped structure is fully utilized between the two. When the wedge-shaped portion 32 of the light-transmitting member 3 fits with the wedge-shaped surface 101 of the light outlet 10. Since the inward axial self-locking force can be generated between the wedge-shaped structures, the wedge-shaped portion 32 fits tightly with the wedge-shaped surface 101. This makes the connection gap between the two smaller, and the connection method of the wedge structure makes the contact area between the light-transmitting member 3 and the housing 1 larger, thereby achieving a more tightly connected effect between the two.

[0073] In summary, this embodiment brings the following beneficial effects:

[0074] Firstly, the sealing between the light-transmitting member 3 and the housing 1 is enhanced, and the possibility of light leakage is reduced as the gap is reduced, thereby achieving a better light leakage prevention effect.

[0075] Secondly, the stability of the optical performance is increased. The smaller the connection gap between the two, the better the connection stability and relative positioning performance between the two, which is conducive to the accurate emission of light.

[0076] Thirdly, the vibration resistance is enhanced, the connection gap between the two is reduced, and the matching area is increased, which can enhance the mechanical support performance of the connection between the light-transmitting member 3 and the housing 1, thereby enhancing the ability to resist external vibration.

[0077] Fourthly, the service life of the beauty instrument of the present application can be extended. A small gap means that the relative movement and wear opportunities of the two fittings are reduced, so that the service life of the structure can be extended.

[0078] In general, the wedge-shaped structure can be used to reduce the connection gap between the light-transmitting component 3 and the housing 1, which can effectively enhance the service life and optical performance quality of the light-transmitting structure of the beauty instrument.

[0079] Reference Figures 2 to 6 In some embodiments, the accommodating cavity 11 proposed in the embodiments of the utility model includes a side wall 11a and a bottom wall 11b, the wedge surface 101 is connected to the bottom wall 11b of the accommodating cavity 11, the side wall of the sealing member 2 connecting the first surface 23 and the second surface 24 is abutted against the side wall 11a of the accommodating cavity 11, and the first surface 23 is abutted against the bottom wall 11b of the accommodating cavity 11.

[0080] In this embodiment, the side wall 11a and the bottom wall 11b of the accommodating cavity 11 provide space for accommodating the light-transmitting member, and the side wall 11a and the bottom wall 11b of the accommodating cavity 11 are arranged to match the outer profile of the sealing member 2, thereby indirectly achieving a better positioning effect of the light-transmitting member 3. The wedge-shaped surface 101 is connected to the bottom wall 11b of the accommodating cavity 11, and the wedge-shaped surface 101 matches the wedge-shaped portion 32 of the light-transmitting member 3, thereby achieving reliable positioning and fixing of the light-transmitting member 3.

[0081] The side wall of the seal 2 abuts against the side wall 11a of the accommodating cavity 11, and the first surface 23 abuts against the bottom wall 11b of the accommodating cavity 11, so that the seal 2 and the housing 1 are sealed and matched in the radial and axial directions, and the connection stability between the light-transmitting member 3 and the housing 1 is enhanced. The light-emitting surface 3b of the light-transmitting member 3 is aligned with the light-emitting port 10 of the housing 1 to form an accurate light path.

[0082] In summary, the present embodiment has formed a structure of accurate positioning and multi-faceted sealing of the light-transmitting member 3 through the above-mentioned arrangement, which effectively improves the sealing, stability and optical performance of the beauty instrument of the present application, so that the beauty instrument of the present application can work stably and reliably. It is also conducive to simplifying the installation process and facilitating quick assembly.

[0083] Reference Figure 7 and 8 In some embodiments, the beauty instrument proposed in the embodiment of the utility model further includes a pressing plate 4, which is detachably connected to the shell 1, the pressing plate 4 abuts against the sealing member 2, and the pressing plate 4 is provided with an avoidance opening 40, which is respectively opposite to the light outlet 10 and the light entrance hole 22.

[0084] In this embodiment, the pressure plate 4 is installed in a detachable connection with the housing 1 and abuts against the seal 2. Such a setting can make the pressure plate 4 generate an axial pressing force on the seal 2, and the pressing force is directed to the direction of the light outlet 10. An additional pressing contact force is formed between the seal 2 and the light-transmitting member 3, which enhances the sealing effect between them and improves the mechanical stability of both. Furthermore, the light-transmitting member 3 transmits pressure to the housing 1, that is, the pressing force is finally transmitted from the wedge-shaped portion 32 to the wedge-shaped surface 101, so that the tightness of the connection between the light-transmitting member 3 and the housing 1 is further improved.

[0085] At the same time, the avoidance opening 40 of the pressing plate 4 is respectively arranged opposite to the light outlet 10 of the shell 1 and the light entrance hole 22 of the sealing member 2, so that the light emitted from the light-emitting component inside the beauty instrument toward the light-transmitting component 3 can pass through the pressing plate 4 smoothly. The pressing plate structure is equivalent to an additional clamping mechanism. Through its pressure, it can significantly enhance the fixing effect of the light-transmitting component 3, making its position and direction more stable and accurate, and can significantly enhance the tightness of the connection between the light-transmitting component 3 and the shell 1. The structure is simple and effective. Not only does it have little effect on the light path emitted by the light-emitting component. It also enhances the mechanical strength and stability of the overall connection. It does not increase the complexity of the optical system, but also achieves better positioning and fixation of the light-transmitting component 3, which has good practicality.

[0086] Reference Figure 2 and Figure 8 The housing 1 of the embodiment of the utility model is further provided with at least two second connecting members 13 , which are symmetrically arranged on both sides of the light outlet 10 , and one end of the pressing plate 4 away from the sealing member 2 is screwed to the second connecting member 13 .
