Here, 'collecting' may mean a function of the mask device 100 corresponding to a process in which the floating particles 20 are adsorbed to the filter layer.

Meanwhile, the mask device 100 according to an embodiment of the present disclosure may perform a filter regeneration function for the filter layer. Accordingly, the user 10 can reuse the mask device 100 several times without replacing the filter layer of the mask device 100 .

Hereinafter, various embodiments in which the mask device 100 can be reused several times without replacing the filter layer will be described in more detail.

According to FIG. 2 , the mask device 100 may include a first filter layer 110 , a first electrode layer 120 , a second electrode layer 130 and a processor 140 .

The first filter layer 110 according to an embodiment of the present disclosure may be a filter layer related to a function of collecting suspended particles in the air. Here, the first filter layer 110 is an electrically polarized fiber and may have a non-uniform weave (or irregular pattern) composition structure. Accordingly, since the floating particles are adsorbed to the polarized fibers constituting the first filter layer 110, it is possible to prevent the floating particles from entering the user's respiratory system. However, since the polarization of the fibers constituting the first filter layer 110 is gradually weakened as the user uses the mask device 100, the filter regeneration function for the first filter layer 110 for continuous use of the mask device 100 this can be done

In particular, the mask device 100 may include a plurality of

electrode layers

Like the first electrode layer 120, the second electrode layer 130 according to an example may also be implemented with a conductive material. Here, the size of the second electrode layer 130 may be the same as that of the first electrode layer 120, but is not limited thereto.

According to an example, at least one surface, that is, both surfaces or one surface of each of the first electrode layer 120 and the second electrode layer 130 may be coated with a dielectric material. Dielectric is a material that generates electric polarization but does not generate direct current when an electrostatic field is applied. When the electrode layer is coated with the dielectric, it is possible to prevent sparks from occurring on the surface of each

electrode layer

120, 130, and mask The filter layer included in the device 100 may be prevented from being damaged.

Meanwhile, the first electrode layer 120 and the second electrode layer 130 may be implemented as at least one of a pin type, a wire type, a mesh type, or a plate type, but are limited thereto. It is not.

The processor 140 controls the overall operation of the mask device 100 . Specifically, the processor 140 may be connected to each component of the mask device 100 to control the overall operation of the mask device 100 .

According to one example, a visible light catalyst obtained by adding Ag or Pt to TiO ₂ or WO ₃ or a composite thereof may be used.

According to one example, a surface of the third filter layer adjacent to the second electrode layer 130 may be coated with a contamination inhibitor. Specifically, in order to prevent contamination of the mask device 100 by adsorption of sebum or cosmetics of the user using the mask device 100 to the third filter layer, the third filter layer prevents the user's sebum or cosmetics from being easily adsorbed. In order to do so, it may be coated with a contamination inhibitor having hydrophilicity.

According to another example, the third filter layer may include a contamination inhibiting layer disposed in a direction adjacent to the second electrode layer 130, and the contamination inhibiting layer may be made of rubber or silicon having a predetermined thickness or more.

According to another example, the third filter layer may be implemented with fluorine fibers. Here, when the third filter layer is implemented with fluorine fiber, since the third filter layer has non-wetting, the mask device 100 may not include a separate contamination suppression layer.

According to another example, a surface adjacent to the second electrode layer 130 may be coated with a contamination inhibitor instead of the third filter layer not including the contamination inhibition layer. Fluorine fibers coated with a stain inhibitor have the advantage that their surface is not easily contaminated and that the contaminated surface is easy to clean.

In the above, it has been described that the processor 140 controls the mask device 100 so that the first electrode layer 120 becomes an anode and the second electrode layer 130 becomes a cathode, but the processor 140 controls the first electrode layer 120 to become a cathode. , the mask device 100 may be controlled so that the second electrode layer 130 becomes an anode. In this case, the direction of the electric field for the first filter layer 110 may be generated in the opposite direction to the previous one, but the sterilization function is performed using the generated electric field. .

Here, the mask device 100 may further include a guide so that the first filter layer 110 does not contact the first electrode layer 120 and the second electrode layer 130 . Specifically, the mask device 100 according to an example includes a first guide (not shown) formed on the first electrode layer 120 in the direction of the first filter layer 110 and the second filter layer 110 on the second electrode layer 130. A second guide (not shown) formed in a direction may be further provided, and the processor 140 may control the mask device 100 such that a potential difference between each guide becomes zero.

According to FIG. 4 , the first filter layer 110 may have a composition structure in which electrically polarized fibers are non-uniform weave (or non-uniform pattern). The suspended

particles

410, 420, and 430 in the air may be charged with a specific charge or electrically polarized. As described above, when the electric polarization of the mask device 100 is weakened due to repeated use of the device, the adsorption function of the suspended

particles

410, 420, and 430 is weakened, and thus filter regeneration is required.
