Description

Technical Field

[0001] This invention relates to the field of beauty care equipment technology, specifically to a flexible phototherapy mask. Background Technology

[0002] With the expanding application of phototherapy technology in skin care, medical aesthetics, and adjunctive treatments, phototherapy masks, as devices used to support phototherapy components and worn on the face, are widely used in these fields. Existing phototherapy masks typically include the mask body, phototherapy components, and a wearing structure for securing the mask.

[0003] In practical use, phototherapy masks need to maintain a stable fit under different face shapes to ensure the relative positional relationship between the phototherapy components and the skin. However, due to the significant differences in facial contours and the variations in tightness during wear, relying solely on the flexible deformation of the mask itself or the length adjustment of the wearing structure often makes it difficult to achieve full expansion and uniform fit of the mask in the initial stage of wear, affecting wearing comfort and user experience.

[0004] In existing technologies, adjusting the fit of phototherapy masks typically requires multiple manual operations by the user, such as repeatedly adjusting the tightness of the wearing structure or readjusting the mask position. This involves numerous steps and limits ease of use. Furthermore, after wearing the mask, if fine-tuning of the fit or loosening of the fixation is needed, the above adjustment process often needs to be repeated, resulting in insufficient flexibility.

[0005] In addition, existing phototherapy masks are mostly integrally molded or fixed structures when not in use, making it difficult to achieve effective folding while maintaining structural integrity. This results in a large storage volume, which is not conducive to carrying and storing.

[0006] Therefore, how to make phototherapy masks better adapt to different facial features during wear without increasing the complexity of use, while taking into account wearing comfort, ease of adjustment and storage performance, remains a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0007] The main objective of this invention is to provide a flexible phototherapy mask that can solve the above-mentioned problems.

[0008] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a flexible phototherapy mask, comprising:

[0009] The mask assembly includes a flexible mask body, a phototherapy component disposed inside the mask body, and an airbag structure disposed on the mask body. A through-hole seat is symmetrically arranged on both sides of the mask body. An inflation groove is provided in the through-hole seat, and a pressure block is movably arranged in the inflation groove. A strap assembly passes through the through seat, and the strap assembly is provided with extrusion structures arranged along its length direction; The pressure block protrudes at least partially into the through-hole of the through seat; during the process of the strap assembly passing through the through seat from back to front in a single direction, the extrusion structure sequentially extrudes the pressure block to generate reciprocating motion in the inflation groove, thereby compressing air and inflating the airbag structure; and when the strap assembly moves in the opposite direction relative to the through seat, the extrusion structure does not drive the pressure block to generate the corresponding inflation reciprocating motion.

[0010] Furthermore, the inflation groove is provided with at least one elastic compression column, one end of which is fixed to the inner wall of the inflation groove and the other end is connected to the pressure block; the edge of the pressure block is provided with a sealing ring, and the inflation groove is connected to the airbag structure through an air pipe.

[0011] Furthermore, the strap assembly includes an elastic band and an insert connected to the end of the elastic band; the extrusion structure consists of a plurality of protruding teeth disposed on the side of the insert. The protruding end of the pressure block has an inclined surface facing the back of the mask body, which is used to contact the protruding teeth and receive force.

[0012] Furthermore, the through seat is also provided with a clutch adjustment mechanism, which is used to switch the contact state between the insert and the pressure block; The clutch adjustment mechanism includes a limiting piece disposed in the through-hole and a pressing protrusion disposed outside the through-seat; the pressing protrusion has a protruding end extending into the through-hole for pressing the insert piece toward the pressing block so that the protruding teeth contact the pressing block.

[0013] Furthermore, the airbag structure includes an inner airbag and an outer airbag; The inner airbag is disposed on the mask body and is used to expand the mask body to form a support frame when it inflates. The outer airbag is positioned between the mask body and the face to improve fit and adjust the distance between the skin and the phototherapy components.

[0014] Furthermore, the through seat includes an upper through seat and a lower through seat; The air tube corresponding to the upper through seat leads to the inner airbag; The trachea corresponding to the lower through-seat leads to the outer airbag.

[0015] Furthermore, both ends of the insert are provided with limiting strips that cannot pass through the through-hole, which are used to limit the maximum travel of the strap assembly.

[0016] Furthermore, both the inner and outer airbags are equipped with a deflation valve, which is used to release the air inside the airbag when not in use to achieve folding and storage of the mask.

[0017] Furthermore, the mask body is made of a flexible material, and the inserts in the strap assembly are made of an elastic material.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention provides a physical support frame for the mask body when the inner airbag is inflated by setting an inner airbag on the mask body. This allows the flexible material that was originally in a collapsed state to be quickly expanded and maintain a stable spatial structure, effectively avoiding the problems of obstructed vision and uneven distribution of light source caused by material shrinkage.

[0019] 2. This invention achieves the technical effect of simultaneous inflation during the wearing of the mask by coordinating the adjustment and tightening action of the strap assembly with the reciprocating motion of the pressure block. It transforms the wearing and adjustment steps into a power source for mechanical inflation, eliminating the need for an external inflation device, simplifying the overall structure and improving ease of use.

[0020] 3. By setting an outer airbag, this invention achieves the function of establishing an adjustable buffer layer between the mask body and the user's face. The elastic deformation characteristics of the airbag improve the mask's adaptability to different facial contours and wearing comfort. Furthermore, by controlling the inflation volume, the physical distance between the skin surface and the phototherapy components can be adjusted, ensuring the stability of phototherapy energy input.

[0021] 4. This invention achieves human-controlled management of the inflation process by setting a clutch adjustment mechanism composed of press-type protrusions on the through seat. Users can decide whether to start inflation and adjust the final air pressure by switching the contact state between the squeezing structure and the pressure block according to the actual wearing environment and the need for support force.

[0022] 5. By setting a depressurization valve on the airbag structure, this invention enables the inner and outer airbags to quickly deflate and return to their natural crumpled state after use, greatly reducing the storage volume of the mask. Combined with the flexible material's easy bending properties, it significantly improves the device's portability and storage performance. Attached Figure Description

[0029] Reference Figures 1 to 8 This invention discloses a flexible phototherapy mask, whose mask assembly 1 includes a mask body 101 made of a flexible material, such as silicone, fabric, or a composite material thereof. A phototherapy component consisting of an LED light-emitting array is disposed on the inner surface of the mask body 101, and airbag structures are distributed on its outer surface and periphery. Four through-hole seats 102 are symmetrically distributed along the left and right edges of the mask body 101. Figure 3 As shown, the two through-hole seats 102 located at the top are the first group, which are used to fix the upper part of the head circumference in conjunction with one of the strap components 2, and the air tube 1025 is connected to the inner airbag 103; the two through-hole seats 102 located at the bottom are the second group, which are used to fix the lower part of the head circumference in conjunction with another set of strap components 2, and the air tube 1025 is connected to the outer airbag 104.

[0030] The specific mechanical structure of the through-body 102 is as follows: Figure 5 As shown, the through-hole 1021 extends through the entire through-hole 102, allowing the insert 202 in the strap assembly 2 to pass through. An inflation groove 1022 is located to the side of the through-hole 1021, and the base of the pressure block 1023 is located within the inflation groove 1022. A rubber ring with a cup-like effect is tightly fastened at the contact point between the pressure block 1023 and the inner wall of the inflation groove 1022. When the pressure block 1023 moves towards the depth of the inflation groove 1022, the edge of the rubber ring is forced outwards and pressed tightly against the groove wall due to the air pressure inside the inflation groove, thus achieving dynamic sealing during inflation. When the pressure block 1023 moves towards the reset direction, the edge of the rubber ring slightly contracts inwards due to negative pressure and friction, allowing air to enter the interior of the inflation groove 1022 from the gaps in the groove wall. The pressure block 1023 is connected to the bottom wall of the inflation groove 1022 via multiple elastic compression columns 1024. In its natural state, the elastic compression column 1024 is in an extended state, pushing the end of the pressure block 1023 into the through-hole 1021. The end of the pressure block 1023 protruding from the inflation groove 1022 is provided with a slope, which faces the back of the mask body 101.

[0031] The strap assembly 2 includes a double-layered elastic band 201, with flexible plastic inserts 202 connected to both ends. Multiple protrusions 2021 are provided along the length of one side of each insert 202. Parallel limiting pieces 1026 are provided on the upper and lower sides inside the through-hole 1021, constraining the inserted insert 202 within a specific track. Due to the physical constraint of the limiting pieces 1026, a certain gap is maintained between the protrusions 2021 on the insert 202 and the pressure block 1023 in the initial insertion state, allowing the insert 202 to slide freely in both directions within the through-hole 1021. A press-type protrusion 1027, employing a self-locking press structure similar to a ballpoint pen, is provided on the outer side of the through-hole 102. When the press-type protrusion 1027 is pressed inward once, its end extending into the through-hole 1021 will squeeze the insert 202 toward the inflation groove 1022, causing the protrusion 2021 to abut against the inclined surface of the pressure block 1023.

[0032] In this state, due to the guiding effect of the inclined surface of the pressure block 1023, when the insert 202 passes through the through seat 102 from the back to the front (i.e., towards the tension direction), the protrusion 2021 will periodically squeeze the pressure block 1023. After being subjected to force, the pressure block 1023 overcomes the elastic force of the elastic compression column 1024 and moves towards the depth of the inflation groove 1022, compressing the air in the inflation groove and delivering it to the airbag through the air tube 1025. When a protrusion 2021 passes over the pressure block 1023, the elastic compression column 1024 drives the pressure block 1023 to reset, and a negative pressure is generated in the inflation groove 1022 to draw in air. As the strap assembly 2 is continuously pulled, multiple protrusions 2021 sequentially trigger the reciprocating pump action of the pressure block 1023 to achieve inflation. When the insert 202 attempts to slide in the opposite direction, a one-way limiting fit is formed between the protrusion 2021 and the pressure block 1023, thereby preventing the strap assembly from accidentally loosening.

[0033] When wearing the mask, the user first positions the upper strap assembly 2 behind the through-hole seat 102. Pressing the upper press-type protrusion 1027 once causes the protrusions 2021 to contact the pressure block 1023. Then, pulling the insert 202 causes the upper through-hole seat 102 to inflate the inner airbag 103 with air. The tension generated by the inflated inner airbag 103 expands the flexible mask body 101 outwards, forming a semi-rigid support frame. This prevents the mask from collapsing, exposing the eye openings and displaying the light-emitting area. After the mask frame is formed, the user puts on the mask and then pulls the lower strap assembly 2. Specifically, by controlling the displacement length of the lowered insert 202, the user can precisely determine the number of protrusions 2021 passing through the pressure block 1023. Since each tooth 2021 drives the pressure block 1023 to complete one reciprocating stroke as it passes through the pressure block 1023, the total inflation level of the outer airbag 104 can be digitally adjusted by adjusting the pulling stroke of the insert 202. The outer airbag 104 is located between the inner side of the mask body 101 and the face. As the inflation volume increases, the outer airbag 104 expands towards the face, using the flexibility of its airbag wall to generate adaptive physical deformation, thereby filling the space gaps between the forehead, cheekbone, and jaw area of ​​different users and the mask body 101, achieving a soft and snug fit to the facial contours. At the same time, after inflating, the outer airbag 104 acts as an elastic distance adjuster between the mask body 101 and the skin. By changing its inflated thickness, the irradiation distance between the mask body 101 and the skin can be compensated and fine-tuned, ensuring that the light emitted by the phototherapy component can act evenly on the skin surface with a preset irradiance.

[0034] After use, the user presses the push-button 1027 again to reset it. At this time, the insert 202 loses its squeezing force and disengages from the pressure block 1023 under the action of the limiting piece 1026, and the strap assembly 2 returns to a free sliding state for easy removal. Finally, the air is released by turning or pressing the deflation valve 105 on the airbag. After the air in the inner airbag 103 and the outer airbag 104 is released, the mask body 101 returns to its soft, unsupported initial state. The limiting strip 2022 prevents the insert 202 from completely detaching from the through seat 102, and the user can directly fold and store the mask body 101 without the need for an external power source.
