The embodiment relates to a mask module for irradiating light to a face and a manufacturing method thereof.

Recently, as interest in beauty has increased, the popularity of LED masks that irradiate light on the face is high.

In general, an LED mask is manufactured by mounting an SMD type LED package (including red LED, near-infrared LED, etc.) on an FPCB and inserting it into a plastic case. Accordingly, the inner surface of the case is irradiated with light while being separated from the user's face by a predetermined distance.

As a result, there is a problem in that the light significantly less than the amount of light required for skin care is irradiated, and thus, the cosmetic effect is hardly shown. In addition, it can dry out the skin, resulting in damage to the skin.

The embodiment provides an LED mask capable of irradiating the amount of light required for skin care.

In addition, an LED mask with improved massage effect by preventing skin dryness is provided.

The problem to be solved in the embodiment is not limited thereto, and it will be said that the solution to the problem described below or the purpose or effect that can be grasped from the embodiment is also included.

A mask module according to an embodiment of the present invention includes an elastic pad having a shape corresponding to a user's face shape; a cover mask having a shape corresponding to a user's face shape; and a plurality of light emitting elements disposed on the cover mask or the elastic pad to emit light.

The elastic pad includes inner and outer surfaces corresponding to the shape of the user's face, and the cover mask includes inner and outer surfaces corresponding to the shape of the user's face.

The elastic pad may be disposed on the user's face to suppress moisture evaporation.

The elastic pad includes a silicon material, and may have a thickness of 0.1 mm to 10.0 mm.

The elastic pad may be directly attached to the user's face, and the cover mask may include a fixing unit fixed to the user's face.

A case disposed outside the cover mask may be included.

A mask manufacturing method according to one aspect of the present invention includes obtaining face shape information of a user; manufacturing a plurality of masks using the face shape information; and manufacturing an elastic pad corresponding to face shape information using the plurality of masks.

The step of manufacturing the plurality of masks. A first molding mold and a second molding mold for manufacturing the elastic pad may be manufactured using the face shape information, and the shape of the first molding mold and the shape of the second molding mold may be the same.

In the manufacturing of the elastic pad, the elastic pad may be manufactured by filling a resin between the first molding mold and the second molding mold.

In the manufacturing of the plurality of masks, a first molding mold, a second molding mold, and a cover mask are manufactured, and the cover mask may have openings formed at locations where the user's eyes, nose, and mouth are disposed.

A step of assembling a mask module using the elastic pad may be included after the step of manufacturing the elastic pad, and the step of assembling the mask module may include disposing a plurality of light emitting devices on the cover mask.

According to the embodiment, since the elastic pad is in close contact with the face, moisture evaporation is suppressed, thereby preventing the face from becoming dry. Therefore, light having enough power to improve the skin can be irradiated.

1 and 2, the mask module according to the embodiment includes an elastic pad 30 having a first inner surface 31 corresponding to the shape of a user's face, and a second inner surface 31 corresponding to the first inner surface 31. It includes a cover mask 20 having an inner surface, and a plurality of light emitting elements 60 radiating light toward a user's face or skin.

The elastic pad 30 may have a first inner surface 31 and a first outer surface corresponding to the face shape 2 of the user 1 . The elastic pad 30 may be individually manufactured according to the shape of the user's face. By manufacturing the elastic pad 30 according to the user's face shape information, the elastic pad 30 can adhere to the user's face when worn. Here, close contact may be defined as having a contact area of 70% or more with a distance of 1 mm or less from the user's face based on 100% of the area of the elastic pad 30 .

The elastic pad 30 may be made of an elastic material so as not to excessively press the user's face. Illustratively, the elastic pad 30 may be made of a polymer resin such as silicon, but is not necessarily limited thereto. The elastic pad 30 can be selected without limitation as long as it can transmit light and is made of an elastic material.

The elastic pad 30 may have a thickness of 0.1 mm to 10.0 mm. If the thickness is less than 0.1 mm, it is too thin and may be torn during use. If the thickness is greater than 10.0 mm, there is a problem of giving pressure to the face due to the weight, and it is difficult to manufacture finely to correspond to the shape of the face.

The elastic pad 30 may include openings 32 and 33 exposing the user's eyes and nose. In addition, although not shown in the drawings, an opening exposing the user's mouth may be further included. However, it is not necessarily limited thereto, and some openings may not be formed as needed.

The cover mask 20 may be made of a plastic material, but is not necessarily limited thereto, and various materials having a predetermined strength may be selected. Both inner and outer surfaces of the cover mask 20 may have the same shape as the user's face. Like the elastic pad 30, the cover mask 20 can be individually manufactured using information on the shape of a user's face.

The cover mask 20 may include openings 25 and 26 exposing the user's eyes and nose. In addition, although not shown in the drawings, an opening exposing the user's mouth may be further included. However, it is not necessarily limited thereto, and some openings may not be formed as needed.

The user may wear the cover mask 20 after first attaching the elastic pad 30 to the face. That is, the elastic pads 30 may be manufactured separately without being fixed to the cover mask 20 . A reflective film (not shown) is coated on the inner surface of the cover mask 20 to reflect light reflected from the user's skin back toward the skin.

The plurality of light emitting devices 60 may be disposed on the cover mask 20 or the elastic pad 30 to emit light toward the first inner surface 31 of the elastic pad 30 . Accordingly, the light passing through the elastic pad 30 may be irradiated to the user's face or skin. An insertion groove 23 into which the light emitting device 60 and the circuit board 70 can be inserted may be formed on an inner surface of the cover mask 20 .

The plurality of light emitting devices 60 may emit light of a wavelength band beneficial to the skin. Illustratively, the plurality of light emitting devices 60 may have at least one output wavelength of 390 nm, 450 nm, 580 nm, 630 nm, and 700 nm. Also, the plurality of light emitting devices 60 may have different output wavelengths. Illustratively, the plurality of light emitting devices 60 may emit light in a near-infrared wavelength range of 600 nm to 940 nm wavelength range.

The plurality of light emitting devices 60 may be light emitting diodes, organic light emitting diodes, or laser diodes. That is, the plurality of light emitting elements are not particularly limited as long as they can emit light to improve facial skin tone or to help maintain facial elasticity.

The case 10 may be coupled to the cover mask 20 to protect the outer appearance of the mask module. The case 10 may have a window 11 through which the user can observe the outside.

When the case 10 is attached, since the cover mask 20 can be manufactured to have only functional parts, the manufacturing process can be simplified. When the cover mask 20 is the outermost cover, it is necessary to separately finish the cover mask.

That is, the elastic pad 30 and the cover mask 20 are manufactured in a customized shape according to the user, but the case 10 may be manufactured in a single standardized size. While the case 10 is manufactured to have a streamlined shape, the cover mask 20 may be manufactured to correspond to the shape of a user's face. Thus, a gap may be formed between the case 10 and the cover mask 20 .

The case 10 or the cover mask 20 may accommodate necessary parts of the mask module, for example, a control module, a circuit module, a power module, and the like.

A fixing unit (not shown) connected to the cover mask 20 or the case 10 to fix the mask module to the user's head may be further included. The fixing unit may be a band type, but is not particularly limited as long as it is connected to the cover mask 20 or the case 10 and can be fixed to the user's head.

Figure 3 is a conceptual diagram of a mask module according to a second embodiment of the present invention, Figure 4 is a view showing that the elastic pad is in close contact with the face to prevent moisture evaporation, Figure 5 is a gap between the conventional LED cover mask and the face This is a diagram showing the state in which sweat evaporates.

Referring to FIGS. 3 and 4 , the cover of the mask module according to the embodiment may be omitted. That is, the mask module may be composed of the elastic pad 30 and the cover mask 20 . At this time, necessary parts of the mask module, such as a control module, a circuit module, a power module, and the like may be connected to the cover mask 30 .

According to the embodiment, since the inner and outer surfaces of the cover mask 20 have shapes corresponding to the shape of the user's face, the light emitting devices 60 mounted on the cover mask 20 may be arranged along the shape of the user's face. can Accordingly, light may be radiated substantially perpendicular to the user's face. As a result, it is possible to improve light injection efficiency by minimizing light reflection from the skin.

According to the embodiment, since the elastic pad 30 is in close contact with the face, moisture 3 such as sweat generated by light irradiation is not discharged to the outside, so that the moisturizing effect can be maintained. In addition, since the skin does not dry, there is an advantage in that the intensity of light can be sufficiently increased to maximize the cosmetic effect.

Referring to FIG. 5, in the case of a conventional LED mask, since a gap G1 exists between the inner surface of the cover mask 20 and the face, moisture (sweat) and heat generated by light irradiation are easily discharged to the outside, so that the skin may dry out. When the light output is increased while the skin is dry, the skin may be damaged. In addition, since the LEDs are not disposed along the face, the light is not vertically incident, resulting in poor injection efficiency.

A plurality of circuit boards 70 may be disposed on an inner surface of the cover mask 20 . Slits 71 may be formed in the plurality of circuit boards 70 in a horizontal or vertical direction. According to this configuration, the circuit board 70 can be freely bent according to the shape of the user's face. In addition, it is possible to improve the problem that the circuit board 70 is damaged even when the cover mask 20 or the elastic pad 30 is bent due to repeated use.

The number and shape of the plurality of circuit boards 70 are not particularly limited. That is, the number of circuit boards 70 , the shape of the circuit boards 70 , and the number of light emitting devices 60 may be appropriately adjusted so that light can be uniformly irradiated to the user's face. A plurality of circuit boards 70 may be connected to the power/control module 80 .

It has been described that the plurality of light emitting devices 60 are disposed in the insertion groove formed in the cover mask 20, but is not necessarily limited thereto. As shown in FIG. 7 , when the elastic pad 30 is sufficiently thick, the light emitting element may be disposed on the inner or outer surface 32 of the elastic pad 30 . In this case, the mask module may be composed of only the elastic pad 30 without a cover mask.

Referring to FIG. 8 , the light emitting device 60 may be disposed inside the elastic pad 30 and may form an exterior with the case 10 . That is, the user may attach the elastic pad 30 to the face and wear the case 10 . However, it is not necessarily limited thereto and may be used by attaching only the elastic pad 30 without mounting the case 10 .

For example, the user's face shape information may be acquired using a face shape measuring device such as the laser scanners SL1, SL2, and SL3, but is not necessarily limited thereto.

For example, when a user downloads and executes an app on a terminal such as a smartphone possessed by the user, the app is driven and the terminal can operate in a laser scan mode. When the user scans his/her face in a way instructed by the app, face shape information is stored in the terminal and can be transmitted to the server.

However, it is not necessarily limited thereto and may be applied to areas requiring skin massage such as hands and necks in addition to the user's face without limitation. In particular, when the light emitting element is disposed on the elastic pad, it can be worn on various body parts without limitation. Hereinafter, it will be described as being worn on the user's face by way of example.

In the step of manufacturing a plurality of masks (S20), a mold for manufacturing the cover mask 20 and the elastic pad 30 constituting the mask module may be manufactured.
