Existing technology, such as patent application number 202121233406.6, entitled "An LED Phototherapy Facial Mask," discloses a mask body with multiple LED beads installed on it. However, in existing facial masks, the LED beads are usually simply arrayed on the mask body, resulting in poor light uniformity and ineffective light therapy.

[0003] Therefore, existing technologies still need to be improved and enhanced. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a facial mask device that aims to solve the problem of poor light uniformity in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A facial mask device includes: a facial mask body that fits into the human face and a flexible circuit board disposed within the facial mask body. The flexible circuit board is provided with multiple light-emitting arrays, each light-emitting array including light-emitting units arranged along the height direction of the light-emitting array. The light-emitting units on the same light-emitting array are arranged at equal intervals, and the light-emitting units on adjacent light-emitting arrays are arranged vertically and alternately. The light-emitting angle of the light-emitting unit is greater than 30° and less than 120°.

[0007] The distance between two light-emitting units that are vertically misaligned in adjacent light-emitting arrays is the same as the distance between two adjacent light-emitting units on the same light-emitting array.

[0008] The light-emitting unit has a light-emitting angle of 60°.

[0009] The main body of the mask includes an outer mask layer and an inner mask layer disposed on the outer mask layer, the inner mask layer being in contact with the human face; the distance between the light-emitting unit and the inner mask layer is 6mm-15mm.

[0010] The distance between the light-emitting unit and the inner layer of the mask is 8mm.

[0015] Compared to existing technologies, this utility model provides a facial mask device, comprising: a facial mask body that fits into the human face and a flexible circuit board disposed within the facial mask body. The flexible circuit board is provided with multiple light-emitting arrays, each light-emitting array containing light-emitting units arranged along the height direction of the array. The light-emitting units on the same array are equally spaced, and the light-emitting units on adjacent arrays are staggered vertically.

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] Currently, more and more people are using photon facial masks. These devices are LED masks based on photon skin rejuvenation technology. Through embedded LED circuit boards, they provide various colors of light to promote various biochemical processes in the skin. Existing technology, such as patent application 202121233406.6, entitled "An LED Phototherapy Facial Mask," discloses a mask body with multiple LED beads installed on it. In existing masks, the LED beads are usually simply arrayed on the mask body, resulting in poor light uniformity and limited light angle, leading to unsatisfactory light effects. Furthermore, the limited number of LED beads in existing masks results in insufficient total light intensity. Generally, the total light intensity is increased by enhancing the light intensity of individual LED beads. When increasing the light intensity of individual LED beads, the placement of the LED beads becomes crucial. The placement of the LED beads affects the light intensity; uneven light intensity can cause single points on the skin to be exposed to high-intensity light, causing discomfort or even damage.

[0025] This utility model provides a facial mask device. Please refer to [link / reference]. Figures 1-5The device includes a mask body 1 that fits into the human face and a flexible circuit board 2 disposed within the mask body 1. The flexible circuit board 2 has multiple light-emitting arrays (not shown in the figure), each array containing light-emitting units 21 arranged along the height of the array. The light-emitting units 21 on the same array are equally spaced, and the light-emitting units 21 on adjacent arrays are staggered vertically. The light-emitting angle of each light-emitting unit 21 is greater than 30° and less than 120°. This application improves the problem of poor light uniformity in existing mask devices by arranging the light-emitting units 21 on the flexible circuit board 2 and limiting the light-emitting angle of the light-emitting units 21. It should be noted that in this application, the mask body 1 is fitted to the main area of ​​the human face, which includes the forehead area, the jaw area, and the cheek areas. Within these independent areas, the light-emitting units 21 are arranged at equal intervals according to the same light-emitting array, and the light-emitting units 21 on adjacent light-emitting arrays are staggered vertically. Regarding the layout of the light-emitting units 21 around the eyes, nose and surrounding area, and mouth, the positional relationship of the eyes, nose, and mouth may separate the light-emitting units 21 on the same or adjacent light-emitting arrays. These separated, adjacent light-emitting units 21 are not the focus of this application. The light-emitting array includes light-emitting units 21 arranged along the height direction of the array, meaning the light-emitting units 21 are arranged in a vertical column on the flexible circuit board 2. Traditional mask devices typically have 60-70 light-emitting units, which cannot achieve uniform illumination. In this application, the number of light-emitting units 21 reaches 195, and the positions of the light-emitting units 21 are arranged, and the emission angle of the light-emitting units 21 is limited to ensure that the light is irradiated onto the user's skin as uniformly as possible. Figures 1 to 4 The purpose is to demonstrate the overall structure of the facial mask device, without limiting the position of the light-emitting unit 21 on the flexible circuit board 2.

[0026] Furthermore, the distance between two light-emitting units 21 that are vertically misaligned in adjacent light-emitting arrays is the same as the distance between two adjacent light-emitting units 21 on the same light-emitting array.

[0027] In this embodiment, it is assumed that N columns of light-emitting arrays are arranged on the flexible circuit board, and the light-emitting arrays are arranged along the longitudinal direction. Each column of the N light-emitting arrays includes M light-emitting units 21. Then, among two light-emitting units 21 that are vertically misaligned in adjacent light-emitting arrays, one light-emitting unit 21 is the Mth light-emitting unit 21 in the Nth column of the light-emitting array, and the other light-emitting unit 21 is the light-emitting unit 21 in the (N-1)th column that is vertically or horizontally misaligned with the Mth light-emitting unit 21 in the Nth column of the light-emitting array. Specifically, the distance between the Mth light-emitting unit 21 and the (M-1)th light-emitting unit 21 in the Nth column of the light-emitting array is... The distance between the Mth light-emitting unit 21 in the Nth column of the light-emitting array and the two light-emitting units 21 that are staggered vertically in the (N-1)th column of the light-emitting array is n. That is, the arrangement of the Mth light-emitting unit 21 in the Nth column of the light-emitting array and the two light-emitting units 21 that are staggered vertically in the (N-1)th column of the light-emitting array forms an equilateral triangle. The minimum value of N and the minimum value of M are both 1 and are both positive integers. The maximum value of N and the maximum value of M are related to the size of the mask device. In this application, M and N are used to better describe the arrangement of a light-emitting unit in one array and two light-emitting units 21 that are staggered vertically in adjacent arrays forming an equilateral triangle. It should be noted that in this embodiment, the light-emitting units 21 in the same light-emitting array and adjacent light-emitting arrays are continuously arranged in independent areas in the forehead area, jaw area and both cheek areas.

[0028] In this application, a light-emitting unit 21 on a light-emitting array is arranged in an equilateral triangle with two adjacent light-emitting units 21 of adjacent light-emitting arrays that are staggered vertically and close to each other. This arrangement has the following advantages: 1. Uniform light coverage: The equilateral triangle layout allows the light emitted by each light-emitting unit 21 to uniformly cover the main area of ​​the face around it. Since the distance between the three light-emitting units 21 is equal, the light emitted from each light-emitting unit 21 can irradiate the skin at a similar angle and distance, avoiding the problem of light being too concentrated in some areas and too sparse in others, thereby improving the effect of the mask device. 2. Reduced light spots and shadows: Under the equilateral triangle layout, the light spots generated by adjacent light-emitting units 21 can minimize the problem of excessive light intensity in the overlapping area when they overlap. This is because when the light spots overlap, since the distance between the light-emitting units 21 is equal, the boundaries of the light spots can cancel out some of the excessive light, making the light intensity distribution of the entire irradiation area more uniform. This is beneficial for each light-emitting unit to irradiate the main area of ​​the face around it in a relatively uniform manner. 3. Improve light energy utilization: The equilateral triangle layout allows for more efficient use of the light energy emitted by each light-emitting unit 21. Due to the uniform distribution of light spots and reduced overlap, more light energy can directly act on the irradiation area of ​​the mask device, improving the utilization rate of light energy and thus enhancing the skin care effect of the mask device.

[0029] Furthermore, the light-emitting unit 21 has a light-emitting angle of 60°. Figure 5 In the horizontal direction, 0-1.0 refers to the luminous efficiency coefficient, and 0-90° on the fan-shaped circumference refers to the luminous angle of the luminous unit 21. When the luminous angle is 60° (i.e., ... Figure 5 When the light emission coefficient is close to 0.5 (30° on each side of the central fan-shaped area), the light emission intensity is equal to 1 / 2 of the peak light intensity. The light emission unit 21 with an equilateral triangular lamp layout and a light emission angle of 60° has relatively uniform illumination and better light intensity after the light rays intersect.

[0030] The light emission angle of the light-emitting unit 21 matches the layout of the equilateral triangle. Each light-emitting unit 21 can illuminate the area covered by the adjacent light-emitting unit 21 at the optimal angle, thereby further enhancing the uniformity of light. If the light emission angle is too large, it may cause the light of the adjacent light-emitting unit 21 to overlap, resulting in light waste. If the light emission angle is too small, it may not be able to fully cover the adjacent area, resulting in poor lighting effect. The 60° light emission angle can balance these two problems well, reducing light overlap and waste, and making the lighting effect reach the expected level.

[0031] Furthermore, the mask body 1 includes an outer mask layer 12 and an inner mask layer 11 disposed on the outer mask layer 12, the inner mask layer 11 being in contact with the human face; the distance between the light-emitting unit 21 and the inner mask layer 11 is 6mm-15mm. Within this distance range, the light emitted by the light-emitting unit 21 can evenly illuminate the facial skin, reducing the appearance of light spots and dark areas, ensuring that the skin receives sufficient light as much as possible. At the same time, an appropriate distance can avoid discomfort caused by excessively concentrated or dispersed light, making the user feel more comfortable during the light irradiation process. Preferably, the distance between the light-emitting unit 21 and the inner mask layer 11 is 8mm. An 8mm distance ensures that the light-emitting unit 21 loses less energy during transmission, allowing more effective light to be absorbed by the skin, which helps to improve the light irradiation effect. In addition, the light-emitting unit 21 generates a certain amount of heat during irradiation; an appropriate distance can prevent excessive heat accumulation in the inner mask layer 11, thereby avoiding burns or other damage to the skin. It should be noted that, based on the 60° light emission angle and the 8mm distance between the light emission unit 21 and the inner layer 11 of the mask, the illumination range of a single light emission unit 21 (i.e., the illumination width of the light emission unit in the vertical and / or horizontal directions) can be obtained. Thus, the required spacing between adjacent light emission units 21 can be determined. Given the limited illumination area (i.e., the area where the inner layer 11 of the mask contacts the human body), the number of light emission units 21 can be determined. Therefore, in practice, for different light emission angles and the distance between the light emission unit 21 and the inner layer 11 of the mask, the two factors determine the spacing between the light emission units, and thus determine the number of light emission units 21. In order to make the illumination uniform, the number of light emission units 21 can be selected according to the light emission angle and the distance between the light emission unit 21 and the inner layer 11 of the mask.

[0032] Furthermore, the light-emitting unit 21 is an LED lamp bead, which can emit light of different wavelengths. Different wavelengths of light can target different skin problems. The light emitted by the LED lamp bead is narrow-spectrum light, which can more accurately act on the target tissue and reduce damage to surrounding tissues. The LED lamp bead does not generate high heat during operation and has a long service life and stable energy output characteristics, ensuring a continuous and stable light energy supply during the light irradiation process. The inner layer 11 of the mask is a semi-transparent silicone layer. The semi-transparent silicone helps to improve the light uniformity of the light-emitting unit 21, ensuring that the light emitted by the LED lamp bead can more effectively irradiate the skin. The semi-transparent silicone has good adhesion, which helps the inner layer 11 of the mask to adhere stably to the outer layer 12 of the mask, ensuring the stability of the mask device assembly. Of course, a textured surface can also be provided on the inner layer 11 of the mask to make the light irradiation of the light-emitting unit 21 more uniform.

[0033] Furthermore, a groove for placing the flexible circuit board 2 is provided in the middle of the outer layer 12 of the mask, and the inner layer 11 of the mask is fitted with the periphery stop of the outer layer 12 of the mask. The periphery of the inner layer 11 of the mask is provided with a raised stop 13, and the periphery of the outer layer 12 of the mask is provided with a recessed stop 14. The inner layer 11 and the outer layer 12 of the mask are stably fitted by using an adhesive (such as glue or other adhesive substances similar to glue) through the stop fit. At the same time, it can also prevent external moisture, dust and other impurities from entering the mask body 1 and affecting the irradiation effect of the light-emitting unit 21. The flexible circuit board 2 is placed in the groove in the middle of the outer layer 12 of the mask. The groove limits the position of the flexible circuit board 2 so that the flexible circuit board 2 is centered in the mask device, which makes it easier for the user to accurately align the mask device with the body of the human face and ensure the irradiation effect of the mask device.

[0034] Furthermore, a soft film layer 3 is provided between the flexible circuit board 2 and the inner layer 11 of the mask; the soft film layer 3 is a PVC soft film layer 3, PVC is polyvinyl chloride. The specific layer structure, processing technology and other related information of the PVC soft film layer 3 are existing technologies and will not be described in detail here. During the engagement of the convex stop 13 of the inner layer 11 and the concave stop 14 of the outer layer 12, the edge of the PVC soft film layer 3 can also be pressed into the concave stop 14, so that the PVC soft film layer 3 covers the end face of the outer layer 12, thereby shielding the components of the flexible circuit board 2 and making the appearance of the mask device aesthetically pleasing. When the PVC soft film layer 3 is pressed onto the outer layer 12 by the inner layer 11, the PVC soft film layer 3 is flattened, which can diffuse and homogenize the light from the light-emitting unit 21, making the light distribution on the main body of the human face more uniform. The PVC soft film layer 3 can also play an isolation role, preventing dust, water vapor and other impurities from entering the interior of the mask device, ensuring the cleanliness and hygiene of the interior of the mask device, and improving the service life of the mask device.

[0035] In summary, this utility model provides a facial mask device, comprising: a facial mask body that fits into the human face and a flexible circuit board disposed within the facial mask body. The flexible circuit board is provided with multiple light-emitting arrays, each light-emitting array containing light-emitting units arranged along the height direction of the array. The light-emitting units on the same array are equally spaced, and the light-emitting units on adjacent arrays are staggered vertically. The light-emitting angle of each light-emitting unit is greater than 30° and less than 120°. This application improves the problem of poor light uniformity in existing facial mask devices by arranging the light-emitting units on the flexible circuit board and limiting the light-emitting angle of the units.
