[0046] The present application will now be described in detail. While specific embodiments of the present application are shown, it should be understood that the present application can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0047] It should be noted that certain terms are used in the specification and claims to refer to specific components. Those skilled in the art will understand that different terms may be used to refer to the same component. This specification and claims do not distinguish components based on differences in terminology, but rather on differences in function. The terms "comprising" or "including" used throughout the specification and claims are open-ended and should be interpreted as "comprising but not limited to." The following descriptions in the specification are preferred embodiments for carrying out this application; however, these descriptions are for the purpose of understanding the general principles of the specification and are not intended to limit the scope of this application. The scope of protection of this application shall be determined by the appended claims.

[0048] refer to Figure 1 and Figure 2 This application provides a phototherapy face mask. It includes a mask body 1, which comprises a flat portion and a contact portion; the plane containing the contact portion intersects with the plane containing the flat portion; the mask body 1 has a three-dimensional structure in its normal state; the flat portion is in contact with the five crowns of the face, and the contact portion is in contact with the side of the face.

[0049] The mask body 1 includes an outer layer 3 and an inner layer 2, which are fixedly connected. A circuit layer 4 is provided between the inner layer 2 and the outer layer 3, and the circuit layer 4 is clamped and fixed between the outer layer 3 and the inner layer 2. A cavity is formed between the inner layer 2 and the outer layer 3, and the circuit layer 4 is disposed in the cavity; Both the inner layer 2 and the outer layer 3 are separable from and can be connected to the circuit layer 4.

[0050] The inner layer 2 and the outer layer 3 are separate structures, while the circuit layer 4 located between the inner layer 2 and the outer layer 3 is fixed by the clamping effect between the outer layer 3 and the inner layer 2.

[0051] An encapsulation part 5 and a connecting part 6 are provided on the outer layer 3. The encapsulation part 5 can fix the outer layer 3 to the inner layer 2; the connecting part 6 can limit the circuit layer 4.

[0052] A clearance portion 7 is provided on the line layer 4, and a connecting portion 6 is provided corresponding to the clearance portion 7, with the connecting portion 6 located in the clearance portion 7.

[0053] The encapsulation part 5 is located near the outer edge of the outer layer 3, and the encapsulation part 5 is used to encapsulate and fix the inner layer 2 and the outer layer 3.

[0054] The circuit layer 4 is located between the outer layer 3 and the inner layer 2, connecting the inner layer 2 and the outer layer 3 near their edges, thus sealing the circuit layer 4 internally. This not only secures the circuit layer 4, preventing leakage between the outer layer 3 and the inner layer 2, but also protects it from external impurities and oxidation / corrosion. This improves the lifespan and safety of the face mask body 1.

[0055] refer to Figure 1 and Figure 2 The connecting part 6 and the recessing part 7 are mutually adapted. The connecting part 6 and the recessing part 7 are snapped together. This allows the circuit layer 4 and the outer layer 3 to be snapped and fixed together. After the circuit layer 4 is encapsulated between the inner layer 2 and the outer layer 3, the snapping of the connecting part 6 and the recessing part 7 also restricts the movement of the circuit layer 4 within it. This prevents the circuit layer 4 from shifting during use or storage, which would render the phototherapy mask unusable. After the recessing part 7 of the circuit layer 4 is snapped onto the connecting part 6, when the outer layer 3 and the inner layer 2 are moved, bent, or otherwise deformed, the circuit layer 4 will move along with the connecting part 6 of the outer layer 3, preventing the circuit layer 4 from shifting within the outer layer 3 and significantly improving the stability of the mask body 1.

[0056] The clearance portion 7 penetrates the circuit layer 4; the inner layer 2 and the outer layer 3 are connected in the clearance portion 7, and the circuit layer 4 abuts against the inner layer 2 and / or the outer layer 3 at the clearance portion 7; the clearance portion 7 includes a top clearance groove 72 and a face clearance groove 71.

[0057] refer to Figure 1 and Figure 2 The connecting part 6 can not only connect the circuit layer 4 and the outer layer 3, but also connect the inner layer 2 and the outer layer 3.

[0058] The connecting part 6 of the outer layer 3 passes through the circuit layer 4 and connects to the inner layer 2, so that the connecting part 6 is snapped and fixed in the relief part 7. This not only prevents the circuit layer 4 from shifting, but also limits the inner and outer sides of the circuit layer 4.

[0059] Multiple connecting portions 6 and clearance portions 7 are evenly distributed. The multiple clearance portions 7 and connecting portions 6 work together on the circuit layer 4, making the force on the circuit layer 4 more uniform during movement and reducing the occurrence of deformation of the circuit layer 4. This allows the circuit layer 4, inner layer 2, and outer layer 3 to maintain uniform integrity.

[0060] refer to Figure 2 and Figure 3The top clearance groove 72 is formed near the upper end of the circuit layer 4, and the face clearance groove 71 is formed near the lower end of the circuit layer 4.

[0061] In one specific embodiment, the number of top clearance grooves 72 is greater than the number of face clearance grooves 71. Since the circuit layer 4 is vertical during use, and the circuit layer 4 is made of a flexible material, having multiple top clearance grooves 72 helps improve the stability of the inner layer 2 and outer layer 3 in supporting the circuit layer 4, increasing the force exerted by the outer layer 3 and inner layer 2 on the circuit layer 4. Then, under the influence of gravity, the lower end of the circuit layer 4 can remain flat.

[0062] refer to Figure 2 and Figure 3 The circuit layer 4 includes a face layer 42 located at the lower end, a forehead layer 43 located at the upper end, and a facial features layer 41 located in the middle. The face layer 42 and the forehead layer 43 are connected, and the forehead layer 43 and the facial features layer 41 are connected. There is a gap between the facial features layer 41 and the face layer 42.

[0063] refer to Figure 2 and Figure 3 The facial features layer 41, face layer 42, and forehead layer 43 are integrally formed.

[0064] The top relief groove 72 is formed on the forehead layer 43, and the face relief groove 71 is formed on the face layer 42.

[0065] refer to Figure 2 and Figure 3 The top clearance groove 72 is opened from the top of the forehead layer 43. Multiple top clearance grooves 72 are opened and are evenly opened along the horizontal direction of the forehead layer 43. There are 3 to 30 top clearance grooves 72.

[0066] Specifically, the number of top clearance slots 72 is: 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30.

[0067] refer to Figure 2 and Figure 3 The facial clearance groove 71 is formed starting from the lower edge of the facial layer 42; multiple facial clearance grooves 71 are formed, and the facial clearance grooves 71 are formed at both ends of the lower end of the facial layer 42 near the horizontal direction; furthermore, the facial clearance grooves 71 are formed through the facial layer 42 near the middle of the lower end of the facial layer 42; the number of facial clearance grooves 71 is 1 to 10, preferably 3.

[0068] Specifically, the number of the facial clearance grooves 71 is: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

[0069] In one specific embodiment, the top clearance groove 72 is provided with 8 grooves, and the face clearance groove 71 is provided with 3 grooves.

[0070] refer to Figure 3 and Figure 4 Wearing parts 31 are provided at positions near both sides in the horizontal direction of the outer layer 3. The wearing parts 31 can be used to fix the outer layer 3 and the inner layer 2 to the face.

[0071] An LED bead is disposed on the circuit layer 4 and is electrically connected to the circuit layer 4. An LED bead hole 21 is formed on the inner layer 2 and the LED bead is located in the LED bead hole 21. Preferably, an LED bead adhesive is disposed in the LED bead hole 21, the LED bead adhesive is located on the LED bead, and the LED bead adhesive covers and seals the LED bead.

[0072] refer to Figure 3 and Figure 4 A power-conducting part 8 is provided on the face mask; the power-conducting part 8 is used to electrically connect with the power connector 85 of the face mask, and the power-conducting part 8 is electrically connected to the circuit layer 4. Preferably, the power-conducting part 8 includes a connector 81, which penetrates the face mask body 1 and is electrically connected to the circuit layer 4. More preferably, the connector 81 is made of a power-conducting material. More preferably, the connector 81 is magnetic and can be magnetically attracted. More preferably, a cap 83 is provided at one end of the connector 81 near the outer layer, and an insulating outer shell layer 82 is provided on the outside of the connector 81. The outer shell layer 82 is integrally formed with the connector 81. More preferably, the connector 81 has a rivet structure, and the cap 83 can be riveted and fixed to the connector 81. More preferably, a fixing adhesive is provided at the connection between the connector 81 and the cap 83.

[0073] refer to Figure 3 and Figure 4 The connector 81 is provided in two, and the two connectors 81 are arranged vertically. The connector head 85 is arranged vertically corresponding to the connector 81. More preferably, the connector head 85 is provided with a power cord, and the power cord is located at the lower end of the connector head 85 in the vertical direction. The power supply for the face mask and the wiring layer 4 are connected to form a circuit using two connectors 81. Therefore, the connector 85 has two contacts corresponding to the two connectors 81, and the positive and negative terminals are distinguished. Therefore, when connecting the connector 85 and the connector 81, they must be matched one-to-one.

[0074] refer to Figure 3 and Figure 4 When the face mask is in use, it is applied to the face. Therefore, in this application, the two connectors 81 and the connector head 85 are positioned vertically. This makes it easier for the user to connect the connector head 85 to the connector 81 in a vertical direction, thus achieving a corresponding connection between the connector head 85 and the connector 81. This effectively prevents incorrect connection between the connector head 85 and the connector head 81.

[0075] refer to Figure 3 and Figure 4 Furthermore, placing the power cord of connector 85 at the bottom position better aligns with everyday usage scenarios, allowing users to more clearly understand the connection method between connector 85 and connector 81. On the other hand, if connector 85 and connector 81 are incorrectly connected, the power cord, which should be at the bottom, will be fixed at the top. Under gravity, the power cord will also cause connector 85 to detach from connector 81, preventing incorrect connection and prompting the user to correctly connect connector 85 and connector 81.

[0076] refer to Figure 3 and Figure 4 More preferably, a foolproof structure is provided on the energized part 8, the foolproof structure electrically connecting the connector 85 and the energized part 8; more preferably, the foolproof structure includes a foolproof block 84 disposed on the energized part 8, the foolproof block 84 being located near the center of the energized part 8; more preferably, the foolproof block 84 and the energized part 8 have a non-rotationally symmetrical structure; more preferably, the foolproof block 84 is inclinedly disposed on the energized part 8.

[0077] refer to Figure 3 and Figure 4 The foolproof structure is used to prevent incorrect connection between connector 81 and connector head 85. The foolproof block 84 is disposed between the two connectors 81.

[0078] A misalignment groove corresponding to the misalignment block 84 is provided on the connector 85. When the connector 81 is connected to the connector 85, the misalignment block 84 will engage in the misalignment groove. However, when the connector 85 is connected to the connector 81 in the reverse direction, the misalignment block 84 and the misalignment groove will misalign, preventing the misalignment block 84 from entering the misalignment groove. Consequently, the connector 85 cannot come into close contact with the connector 81 to achieve a connection. This avoids the possibility of damage to the face mask due to incorrect connection between the connector 85 and the connector 81.

[0079] refer to Figure 3 and Figure 4The power-conducting part 8 further includes a housing layer 82, which is located on the outer layer 3 of the connector 81. The housing layer 82 is fixedly connected to the connector 81. Preferably, the connector 81 and the housing layer 82 are integrally formed.

[0080] By using an insert injection molding process to manufacture the connector 81 and the outer shell layer 82, the connection strength between the connector 81 and the outer shell layer 82 can be increased, reducing the possibility of separation between them. Furthermore, it also increases the overall integrity of the outer shell layer 82 and the connector 81, resulting in a smoother and more complete surface of the face mask body 1 after the energized part 8 is installed on it. This avoids defects such as welding or gluing that may occur in the energized part 8 due to connection requirements, thereby improving the yield rate of both the energized part 8 and the face mask body 1.

Simultaneously, the LED beads are aligned with the LED bead holes 21 on the inner layer 2, and the encapsulation portion 5 of the outer layer 3 is welded and fixed to the inner layer 2, sealing the circuit layer 4 entirely between the inner layer 2 and outer layer 3. Finally, adhesive is applied to the LED bead holes 21 for sealing, covering the LED beads.

[0095] This application also provides a method for preparing a phototherapy mask, the phototherapy mask comprising an inner layer 2, a circuit layer 4, and an outer layer 3 connected in sequence, comprising the following steps: First station: Batch production of inner layer 2; can be molded independently without relying on other processes, molding time is about 12 seconds, production is 10 hours per day, one machine can produce 3000 sets.

[0100] The dispensing station is used to add glue to the inner layer 2 to cover the LED beads on the sealing circuit layer 4; it can also be used to seal the connection between the power-conducting part 8 and the mask body 1.

[0101] In this application, a first workstation is set up to independently produce the inner layer 2, and a second workstation is set up to independently produce the outer layer 3. Therefore, the production process of the phototherapy mask can be divided into steps, reducing production difficulty and thus improving the production efficiency of the mask.

[0102] Furthermore, the first and second workstations are independent of each other, producing inner layer 2 and outer layer 3 as independent parts. Therefore, the outer layer 3 and inner layer 2 can be inspected before being connected, thus improving the quality and yield of inner layer 2 and outer layer 3.

[0103] After the inner layer 2 and outer layer 3 are produced independently, the production speed of either the inner layer 2 or the outer layer 3 can be independently controlled based on their consumption rates. This avoids material waste in either the inner layer 2 or the outer layer 3.

[0109] Laser welding is a cleaner and more environmentally friendly joining process, as it does not use any polluting substances. Therefore, even when the phototherapy mask is discarded, it will not cause environmental pollution. Furthermore, laser welding does not produce any toxic or polluting byproducts. The working space for laser welding is also more environmentally friendly and safer.

[0115] Insert molding is a processing method that involves pre-placing an insert in a mold and injecting plastic to encapsulate the insert, forming a one-piece product. The insert can be made of metal or other plastics and can be manufactured through injection molding, compression molding, transfer molding, or other methods.

[0116] By using an insert injection molding process to manufacture the connector 81 and the outer shell layer 82, the connection strength between the connector 81 and the outer shell layer 82 can be increased, reducing the possibility of separation between them. Furthermore, it also increases the overall integrity of the outer shell layer 82 and the connector 81, resulting in a smoother and more complete surface of the face mask body 1 after the energized part 8 is installed on it. This avoids defects such as welding or gluing that may occur in the energized part 8 due to connection requirements, thereby improving the yield rate of both the energized part 8 and the face mask body 1.

[0117] The energized part 8 is riveted to the mask body 1.

[0120] During laser welding, the power of the laser is 100~3000W; preferably, the power of the laser is 300~2400W; more preferably, the laser is a galvanometer or a multi-head synchronous welding process.

[0121] Specifically, the power of the laser is: 300W, 350W, 400W, 450W, 500W, 550W, 600W, 650W, 700W, 750W, 800W, 850W, 900W, 950W, 1000W, 1050W, 1100W, 1150W, 1200W, 1250W, 1300W, 1350W, 1400W, 1500W, 1600W, 1700W, 1800W, 1900W, 2000W, 2100W, 2200W, 2300W, 2400W, 2500W, 2600W, 2700W, 2800W, 2900W, 3000W.

[0122] When the laser power is 2400W, the laser welding speed is 4~12s / piece; preferably, When the laser welding is a multi-head synchronous welding, the laser welding joint will fully weld the inner layer 2 and the outer layer 3.

[0123] In one specific implementation, when using multi-head synchronous welding, one head is welded every 8 seconds.

[0124] Preferably, when the laser welding is galvanometer welding, the speed is 10 mm / s to 70 mm / s.

[0125] Specifically, the laser welding speed for galvanometer welding is 10 mm / s, 15 mm / s, 20 mm / s, 25 mm / s, 30 mm / s, 35 mm / s, 40 mm / s, 45 mm / s, 50 mm / s, 55 mm / s, 60 mm / s, 65 mm / s, and 70 mm / s.

[0126] The speed at which the inner layer 2 is prepared at the first station is equal to the speed at which the outer layer 3 is prepared at the second station.

[0127] This application also provides a phototherapy mask, which includes an inner layer 2 and an outer layer 3. The inner layer 2 is made of TPU material, the outer layer 3 is made of TPU material, and the inner layer 2 contains a light absorber. The light absorber is one of carbon black, iron oxide, phthalocyanine blue, and phthalocyanine green. Preferably, the light absorber is carbon black. More preferably, the light absorber accounts for 0.05% to 0.8% of the inner layer 2. More preferably, the light absorber accounts for 0.1% to 0.5% of the inner layer 2.

[0128] Specifically, the proportions of the light absorber are: 0.05%, 0.06%, 0.08%, 0.1%, 0.12%, 0.14%, 0.16%, 0.18%, 0.2%, 0.22%, 0.24%, 0.26%, 0.28%, 0.3%, 0.32%, 0.34%, 0.36%, 0.38%, 0.4%, 0.42%, 0.44%, 0.46%, 0.48%, 0.5%, 0.52%, 0.54%, 0.56%, 0.58%, 0.6%, 0.62%, 0.64%, 0.66%, 0.68%, 0.7%, 0.72%, 0.74%, 0.76%, 0.78%, and 0.8%.

[0129] Carbon black (most commonly used) has extremely strong absorption in the near-infrared band; even a small amount can absorb a large amount of laser light and convert it into heat energy. It's a standard ingredient in black TPU. However, excessive amounts can lead to heat dissipation, blurred lettering, carbonization and scorching of the TPU when heated, and can also make the material slightly conductive. Recommended addition: 0.1%~0.5%; exceeding 0.8% can easily cause overheating.

[0130] Iron oxides (iron oxide, iron(II) oxide Fe3O4, laser engraving pigments) have excellent infrared absorption, enabling white marking on dark TPU without significant heat dissipation like carbon black. They are commonly used in flexible TPU and medical-grade applications. Standard addition: 0.05%~0.3%.

[0131] Phthalocyanine blue / phthalocyanine green (organic pigments) exhibit visible light color development and high near-infrared absorption, making them suitable for colored TPU laser welding / engraving. They balance color and light absorption without significantly weakening laser penetration. Standard addition: 0.2%~1.0%.

[0132] They can also be mixed, and those skilled in the art can select the color powder as the absorbent according to different color requirements to prepare products of different colors.

[0133] Adding a light absorber to the inner layer 2 helps the inner layer 2 absorb laser energy. When laser welding the inner layer 2 and the outer layer 3, laser energy needs to be delivered to the connection point between the inner layer 2 and the outer layer 3, and then laser sintering is performed to connect the inner layer 2 and the outer layer 3.

[0134] During the welding of inner layer 2 and outer layer 3, the laser enters from the outside of outer layer 3 and passes through it to reach the connection surface between inner layer 2 and outer layer 3. Then, due to the light absorber added to inner layer 2, inner layer 2 can receive the laser, and then the connection surface between inner layer 2 and outer layer 3 is laser-bonded.

[0135] By adding a light absorber to the inner layer 2, the absorption rate of laser energy in the inner layer 2 is increased, thereby improving the efficiency of laser welding between the inner layer 2 and the outer layer 3. Simultaneously, the difference between the inner layer 2 and the outer layer 3 allows the laser to penetrate the outer layer 3 without sintering, until the inner layer 2 and outer layer 3 are joined, bonding them together. This significantly improves the success rate of laser welding between the inner layer 2 and the outer layer 3, reduces the wear and tear on the inner layer 2 and outer layer 3, and lowers the cost of the phototherapy mask.

[0136] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
