[0037] With reference to Figures 1-11 The present application provides a mouth beautifying device, which comprises a lip beautifying assembly 100 and a bite structure for pressing against teeth. The lip beautifying assembly 100 comprises a first mounting seat, a first light therapy component, a first support part for supporting the bite structure, and a first electrode 141 electrically connected to the first light therapy component. The first light therapy mounting seat has an light-out side, the first light therapy component is mounted on the first mounting seat, and the light-emitting surface of the first light therapy component is arranged towards the light-out side. The first support part and the first electrode 141 are both mounted on the light-out side of the first mounting seat. The bite structure has a second support part for detachable connection with the first support part.

[0038] Specifically, the first mounting seat is used to support the first light therapy component. In use, the light-out side of the first mounting seat faces the lips of a user, so that the light-emitting surface of the first light therapy component faces the lips of the user. The light-emitting surface of the first light therapy component can irradiate lip beautifying light of a specific wavelength to the lips, stimulate the formation of collagen in the lips of the user, and promote blood circulation in the lips, thereby improving the appearance of the lips of the user.

[0039] The bite structure is a component that can be held in the oral cavity by the user and pressed between the upper and lower teeth. In use, the bite structure is fixed on the light-out side of the first mounting seat through the connection of the second support part and the first support part. The user can support the lip beautifying assembly 100 at the lip position by holding the bite structure in the oral cavity, so as to be able to use the first light therapy component to beautify the lips.

[0040] With reference to Figure 2 and Figure 3 In some embodiments, the first mounting seat comprises a main body part 120 and a first bracket 110 mounted in the main body part 120; the first light therapy component is located in the main body part 120 and mounted on the first bracket 110; one end of the first bracket 110 is exposed on the light-out side and matched with the end of the bite structure, and the first support part and the first electrode 141 are arranged on the end of the first bracket exposed on the light-out side.

[0041] Specifically, the first support 110 is configured to support the first light therapy component in the first cavity 1201 of the main body 120, and the shape of the first support 110 can be adapted according to the connection mode with the first light therapy component. The main body 120 can be made of a medical-grade silicone material, and the shape of the main body 120 can be adapted to the overall shape of the first support 110 and the first light therapy component, so as to embed the first light therapy component in the first cavity 1201 and protect the first light therapy component. The light-emitting side of the main body 120 is transparent or transparent as a whole, so that the light emitted by the first light plate 130 can pass through the light-emitting side of the main body 120 and irradiate the user's lips. In use, the surface of the main body 120 is in contact with the user's lips to improve the comfort of the user's lips, and the main body 120 also has a certain anti-pollution ability, which is convenient for cleaning and disinfection, and ensures the hygiene and safety during use. In addition, the main body 120 can also play a waterproof sealing role to improve the safety during use.

[0042] For example, the first support 110 can include a first lip support 111 and a second lip support 112, the first lip support 111 is connected to one end of the second lip support 112, and the area of the end face of the second lip support 112 facing the first lip support 111 can be greater than the cross-sectional area of the first lip support 111, so that the end face of the second lip support 112 facing the first lip support 111 forms a positioning surface 1121. The first lip support 111 and the second lip support 112 can be integrally formed, or independently processed and fixed by bonding or connecting members.

[0043] The first support portion can be a support column 1102 protruding on the first lip support 111, and the shape of the support column 1102 can be arbitrary, for example, the cross-sectional shape of the support column 1102 is rectangular or circular. The number of the first support portion can also be arbitrary, for example, the number of the first support portion is two and is arranged at intervals. In addition, the first support portion can also be a support groove recessed on the first lip support 111.

[0044] The main body 120 can include an outer silica gel sleeve 121 and an inner silica gel sleeve 122, the inner silica gel sleeve 122 is covered in the outer silica gel sleeve 121 to form a first cavity 1201 between the outer silica gel sleeve 121 and the inner silica gel sleeve 122, and the inner silica gel sleeve 122 can be provided with a first opening 1202 which has the same shape as the first lip support 111. When assembling, the first light therapy component can be installed on the first support 110 first, then the first opening 1202 of the inner silica gel sleeve 122 is sleeved on the first support 110, and finally the outer silica gel sleeve 121 is wrapped around the second lip support 112 of the first support 110 and is fixed with the inner silica gel sleeve 122 by bonding or the like, so as to encapsulate the first light therapy component in the first cavity 1201 and expose the first connecting end 1101 of the first support 110 on the light emitting side, so as to connect the first support part and the second support part on the occlusion structure. In addition, the main body 120 can also be integrally formed, and the first opening 1202 is expanded by the elasticity of the main body 120, and then the first lamp plate 130 and the like are placed in the first cavity 1201.

[0045] In some embodiments, the first light therapy component includes a first lamp plate 130, a first circuit board 140 for controlling the first lamp plate 130, and a first battery 150 electrically connected to the first circuit board 140, and the second electrode 241 is electrically connected to the second circuit board.

[0046] Specifically, the first lamp plate 130 can be composed of a substrate and a plurality of LED lamp beads uniformly arranged on the substrate, and the light emitting surface of the first lamp plate 130 refers to the surface provided with the LED lamp beads. The wavelength of the light emitted by the LED lamp beads can be 600nm-700nm, so as to beautify the user's lip by the light emitted by the LED lamp beads. The shape of the first lamp plate 130 can be arbitrary, for example, the first lamp plate 130 is arc-shaped and matches the shape of the user's lip, so that the first lamp plate 130 can completely cover the user's lip and better fit the user's lip, improving the user's experience.

[0047] The first lamp plate 130 can be provided with a through hole 131 which has the same cross-sectional shape as the first lip support 111, and is sleeved on the first lip support 111 through the through hole 131. The back surface of the first lamp plate 130 (the surface of the first lamp plate 130 facing away from the light emitting surface) can abut against the positioning surface 1121 to position the connection position of the first lamp plate 130. In addition, the back surface of the first lamp plate 130 can be fixed on the positioning surface 1121 by bonding or the like, so as to ensure the position stability of the first lamp plate 130 in use. When the first lamp plate 130 is sleeved on the first lip support 111 and abuts against the positioning surface 1121, the first connecting end 1101 is located on the front side of the light emitting surface of the first lamp plate 130, so that the light emitting surface of the first lamp plate 130 faces the light emitting side.

[0048] The first circuit board 140 is a printed circuit board, and a plurality of electronic components, such as a microcontroller, an LED driver, and a control circuit for controlling the first lamp plate 130, are integrated on the first circuit board 140. The first battery 150 can be a rechargeable lithium battery, which has a long service life and a high energy density, and can provide sustained and stable power support for the lip makeup assembly 100. The first circuit board 140, the first battery 150, and the first lamp plate 130 can be connected to each other by using wires, so as to be powered by the first battery 150 and controlled by the first circuit board 140.

[0049] The first support 110 can be provided with a first mounting cavity 1103, which is a cavity structure with a certain volume. The side of the second lip support 112 of the first support 110 facing away from the first lip support 111 can be provided with an opening of the first mounting cavity 1103. The first circuit board 140 and the first battery 150 are sequentially mounted inside the first mounting cavity 1103, which can ensure the position stability of the first circuit board 140 and the first battery 150 during use of the lip makeup assembly 100.

[0050] The first electrode 141 is made of conductive metal material, and can be directly welded on the surface of the second circuit board 240 or connected to the first circuit board 140 through wires. The shape of the first electrode 141 can be arbitrary, for example, the first electrode 141 is in a cylindrical shape. The number of the first electrode 141 can also be arbitrary, for example, the number of the first electrode 141 is two and arranged at intervals, and the two first electrodes 141 can correspond to the positive and negative poles of the control circuit in the first circuit board 140, respectively. When the first circuit board 140 is mounted in the first mounting cavity 1103, the first connecting end 1101 of the first lip support 111 is provided with a first mounting hole corresponding to the number of the first electrode 141, and the first electrode 141 is arranged in the mounting hole, so that the end of the first electrode 141 facing away from the first circuit board 140 is exposed at the first connecting end 1101.

[0051] Referring to Figures 1-6 In some embodiments, the occlusion structure is a tooth whitening assembly 200, which includes a second mounting seat, a second light therapy component for light therapy of teeth, and a second electrode 241 connected to the second light therapy component. The second light therapy component is mounted in the second mounting seat, and the second electrode 241 and the second support part are arranged at the end of the second mounting seat close to the first mounting seat. The second electrode is used to contact and conduct with the first electrode 141 when the first support part and the second support part are connected.

[0052] Specifically, the tooth whitening assembly 200 is used for tooth whitening of a user. In use, the user puts part of the second mounting seat into the oral cavity, so that the light emitting surface of the second light therapy component faces the tooth surface. The light emitting surface of the second light therapy component can emit tooth whitening light of a specific wavelength to the tooth of the user, activate the whitening component on the tooth surface, remove the pigmentation on the tooth surface, and improve the color of the tooth. Through the connection of the first support part and the second support part, the first mounting seat and the second mounting seat can be connected to each other, so that the lip whitening assembly 100 and the tooth whitening assembly 200 are connected and fixed to each other. When the user puts part of the tooth whitening assembly 200 into the oral cavity, the lip whitening assembly 100 can be fixed to the lip at the same time. In addition, the first light therapy component and the second light therapy component are connected through the contact of the first electrode 141 and the second electrode 241, so that the first light therapy component and the second light therapy component can be controlled at the same time, and the lip whitening assembly 100 and the tooth whitening assembly 200 can be used at the same time.

[0053] With reference to Figure 4 and Figure 5 In some embodiments, the second mounting seat comprises a bite sleeve 220 and a second support 210 mounted in the bite sleeve 220. The second light therapy component is located in the bite sleeve 220 and connected to the second support 210. One end of the second support 210 is exposed from the bite sleeve 220 and close to one end of the first mounting seat 110. The second support part and the second electrode 241 are arranged at the end of the second support exposed from the bite sleeve.

[0054] For example, the second support 210 can comprise a first tooth support 211 and a second tooth support 212. The first tooth support 211 is connected to one side of the second tooth support 212. The second tooth support 212 can be an arc shape same as the shape of the tooth part of the user. The first tooth support 211 is connected to the outer side of the second tooth support 212. The end of the first tooth support 211 away from the second tooth support 212 is a second connection end 2101. The first tooth support 211 and the second tooth support 212 can be integrally formed or fixed by bonding or fasteners.

[0055] When the first support part is a support column 1102 protruding on the first support 110, the second support part can be a first support groove 2102 for the support column 1102 to be inserted. The shape of the first support groove 2102 can be the same as that of the support column 1102, so that the support column 1102 can be completely inserted into the first support groove 2102. The number of second support parts can be the same as that of first support parts. For example, the number of second support parts can also be two, which are arranged one by one corresponding to the two first support parts. In addition, when the first support part is a support groove recessed on the first support 110, the second support part can be a support column 1102 protruding on the second support 210.

[0056] The bite sleeve 220 can also be made of medical-grade silicone material, and the bite sleeve 220 can be integrally formed, with a second cavity 2201 formed inside to match the shape of the second bracket 210 and the second light plate 230, and having a second opening arranged towards the first mounting seat 110. The second opening can be expanded by the elasticity of the bite sleeve 220, and then the entire second bracket 210 and the second light therapy assembly are embedded into the second cavity 2201. The second connecting end 2101 of the first tooth portion support 211 can extend out of the second cavity 2201 through the second opening, so that the second support portion and the second electrode 241 are exposed to the outside of the bite sleeve 220, facilitating the connection and separation of the tooth whitening assembly 200 and the lip whitening assembly 100. In addition, the bite sleeve 220 can also be provided in a split manner.

[0057] In use, after the user puts the tooth whitening assembly 200 into the oral cavity, the bite sleeve 220 is in contact with the inner surface of the user's oral cavity and the tooth surface, which can improve the comfort of the user in use. Moreover, the second light therapy component is packaged in the second cavity 2201, and the bite sleeve 220 plays a sealing and waterproof role, ensuring the safety in use. Among them, at least a part of the bite sleeve 220 corresponding to the second light plate 230 should be transparent or other color-transmissive, so that the light emitted by the second light plate 230 can penetrate through the bite sleeve 220 to irradiate the tooth surface of the user.

[0058] The side of the bite sleeve 220 facing the user's teeth can be provided with a bite portion 221, which can be in a crescent shape. The bite portion 221 can also be provided with a limiting portion 222, which is a protruding structure provided on the upper and lower surfaces of the bite portion 221 on the side away from the second light plate 230. The distance between the limiting portion 222 and the light-emitting surface of the second light plate 230 is matched with the thickness of the user's teeth to form a limiting groove 2202 in which the user's teeth can be embedded.

[0059] After the user puts the tooth whitening assembly 200 into the oral cavity, the bite portion 221 is located between the two rows of teeth of the user, so as to fix the position of the tooth whitening assembly 200 in the oral cavity of the user by biting the bite portion 221. At the same time, the limiting portion 222 is located inside the teeth, which can limit the tooth whitening assembly 200 from being separated outward from the oral cavity, so that the user does not need to continuously exert the biting force on the bite portion 221, and the position of the tooth whitening assembly 200 can also be maintained, improving the comfort of the user in use and reducing the fatigue feeling in use.

[0060] In some embodiments, the second light therapy component includes the second light plate 230 and a second circuit board 240 for controlling the second light plate 230, and the second electrode 241 is electrically connected to the second circuit board 240.

[0061] Specifically, the second lamp plate 230 can also be composed of a substrate and a plurality of LED lamp beads uniformly arranged on the substrate. The light-emitting surface of the second lamp plate 230 is the side provided with the LED lamp beads. The wavelength of the light emitted by the LED lamp beads can be 400nm-500nm, so as to whiten the user's tooth surface through the light emitted by the second lamp plate 230. The shape of the second lamp plate 230 can be an arc shape matching the shape of the user's tooth part, so that the second lamp plate 230 can be fitted on the tooth surface of the user after being contained in the oral cavity, and the comfort of the user is better while covering all the teeth. The back surface of the second lamp plate 230 (the side of the second lamp plate 230 facing away from the light-emitting surface) can be fixed to the inner side surface of the second tooth part support 212 by bonding or the like, so that the second tooth part support 212 supports the second lamp plate 230 and can be located between the teeth and the lips together with the second lamp plate 230 after being contained in the oral cavity of the user.

[0062] The second circuit board 240 is also a printed circuit board. The second circuit board 240 is also integrated with electronic components such as a controller, an LED driver, and a control circuit for controlling the second lamp plate 230. The second lamp plate 230 and the tooth part control board can be connected to each other by wires, so as to control the opening, closing, irradiation time, and irradiation intensity of the second lamp plate 230 by the tooth part control board.

[0063] The second support 210 can be provided with a second mounting cavity 2103. The second mounting cavity 2103 is a cavity structure with a certain volume. The second mounting cavity 2103 can be arranged on the first tooth part support 211 of the second support 210, and the opening of the second mounting cavity 2103 is formed on the second connecting end 2101 of the first tooth part support 211. Two second support parts are respectively located on both sides of the second mounting cavity 2103. The second circuit board 240 is installed in the second mounting cavity 2103, so as to ensure the stability of the position of the second circuit board 240 of the tooth whitening assembly 200 in use. In addition, the second support 210 can also include a cover plate 213. The shape of the cover plate 213 is the same as the shape of the opening of the second mounting cavity 2103, and the cover plate 213 covers the opening of the second mounting cavity 2103, so as to avoid the exposure of the second circuit board 240.

[0064] The second electrode 241 can also be made of a conductive metal material. The second electrode 241 can be directly welded on the surface of the first circuit board 140, or can be connected to the second circuit board 240 through a wire. The shape of the second electrode 241 can be arbitrary, for example, the second electrode 241 is in a cylindrical shape. The number of second electrodes 241 should be the same as the number of first electrodes 141, for example, the number of second electrodes 241 is two and arranged at intervals, and the two second electrodes 241 correspond to the positive and negative electrodes of the control circuit in the second circuit board 240 respectively. When the second circuit board 240 is installed in the second mounting cavity 2103, the cover plate 213 can be provided with a second mounting hole corresponding to the number of second electrodes 241, and the second electrode 241 is arranged in the mounting hole, so that one end of the second electrode 241 away from the second circuit board 240 is exposed at the second connecting end 2101. The end surface of the second electrode 241 is flush with or slightly protrudes from the second connecting end 2101.

[0065] Referring to Figure 6 When the lip assembly 100 and the tooth assembly 200 are connected through the first support part and the second support part, the first connecting end 1101 abuts against the second connecting end 2101, and the first electrode 141 and the second electrode 241 are located opposite to each other and abut against each other, so that the first circuit board 140 and the second circuit board 240 can be conducted through the first electrode 141 and the second electrode 241. On the one hand, the first circuit board 140 and the second circuit board 240 can be used and controlled at the same time, and on the other hand, the first battery 150 can be used to supply power to the second circuit board 240 and the second lamp plate 230, so as to realize the cooperative work of the first light therapy assembly and the second light therapy assembly. The first electrode 141 can be located between the two first support parts, and the second electrode 241 can be located between the two second support parts, so that the contact between the first electrode 141 and the second electrode 241 is more stable and less likely to separate during use.

[0066] In addition, the second light therapy assembly can further include a second battery 250, and the second battery 250 is installed in the second mounting cavity 2103 together with the second battery 250, and the second battery 250 is used to supply power to the second circuit board 240 and the second lamp plate 230, so as to be able to use the tooth assembly 200 independently.

[0067] Referring to Figures 7-9 In some embodiments, the mouth cosmetic instrument is a mouthpiece 300, and the second support part is arranged on the mouthpiece 300, so that the mouthpiece 300 can be detachably connected to the lip assembly 100.

[0068] As shown in the figure, the mouthpiece 300 can be flat or other structures convenient for users to bite, and the thickness of the mouthpiece 300 can be adjusted as needed to adapt to the natural arrangement of teeth and the size of the oral cavity and biting habits of different users. The mouthpiece 300 can be made of a relatively hard silicone material to adapt to the shape of the oral cavity of different users and provide a more comfortable biting experience for users by taking advantage of the flexibility and durability of silicone. The silicone material also has certain anti-pollution ability, which is convenient for cleaning and disinfection, and ensures the hygiene and safety during use. In addition, the mouthpiece 300 can also be hollowed out to reduce the weight of the mouthpiece 300, so that users do not easily feel tired during long-term use.

[0069] When the first support part is a support column 1102 protruding on the first support 110, the second support part can be a second support groove 301 recessed on the mouthpiece 300. By inserting the support column 1102 on the first support 110 into the second support groove 301 of the mouthpiece 300, the mouthpiece 300 is fixed at the first connection end 1101 of the first support 110, and the user can support the lip beauty assembly 100 on the lips alone by putting the mouthpiece 300 into the oral cavity.

[0070] Referring to Figure 10 and Figure 11 In some embodiments, the mouth beauty instrument further comprises a charging assembly 400, which comprises a charging wire 410, a charging connector 430 and a magnetic connector 420; the charging connector 430 and the magnetic connector 420 are respectively connected to the two ends of the charging wire 410, and the magnetic connector 420 is provided with a third electrode 421 which can be magnetically connected to the first electrode 141 or the second electrode 241.

[0071] Specifically, the charging connector 430 can be a USB connector to enable the mouth beauty instrument to be powered by a USB charger or a USB interface on an electronic device. The charging connector 430 can also be a type-C connector or a Lightning connector to meet the connection needs of different chargers.

[0072] The third electrode 421 can be made of a magnetically conductive material, such as nickel-copper alloy, stainless steel or ferrite, and the first electrode 141 and the second electrode 241 can be made of a metal material that can be magnetically connected. The third electrode 421 can be magnetically connected to the first electrode 141 or the second electrode 241, which can conduct the charging connector 430 and the first circuit board 140 or the second circuit board 240, and connect the charging connector 430 and the external charger to charge the first battery 150. When the second light therapy component does not have a second battery 250, the charging assembly 400 can be kept connected to the tooth beauty assembly 200 to continuously power the second circuit board 240 and the second light plate 230, enabling the tooth beauty assembly 200 to be used independently.

[0073] The above description is only the preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
