Description FUNCTIONAL MASK Technical Field
[1] The present invention relates to a functional mask having sterilizing, worms- destroying, absorbing, filtering and disinfecting functions, and more particularly, to a functional mask which has a breathing part of multi-layers, a detachably mounted filter having the filtering, absorbing, sterilizing and disinfecting functions, and expandable flaps mounted on the right and left sides and the lower end of a mask body, thereby preventing the outside air. Background Art
[2] In general, a commonly used mask except a gas mask is made in such a way that ear strings are mounted on four edges of a fabric of only one fold or many folds. So, the mask prevents cool air in the winter season or prevents some of sandy dust and the outside polluted air generated by factories. However, the conventional mask temporarily prevents some of the polluted air, but cannot filter, absorb, sterilize and disinfect the polluted in the air, and destroy insects.
[3] Furthermore, since the conventional mask is thin and the right and left sides and the lower end of the mask are not in close contact with a user's face, the mask cannot completely prevent the cool air in the winter season, the sandy dust and the polluted air.
[4] However, the general public cannot use the gas mask which is used in a factory for absorption, filtering, sterilization and disinfection or in an army. Disclosure of Invention Technical Problem
[5] Accordingly, the present invention has been made in view of the above problems occurring in the prior art, and it is an object of the present invention to provide a functional mask, which can completely absorb, filter, sterilize and disinfect sandy dust, the outside cool air or polluted air discharged to the air from chemical material treating factories, heavy metal treating factories and so on, and destroy insects. Technical Solution
[6] To completely prevent the outside air, the functional mask according to the present invention includes: a breathing part of multi-layer; a face contacting member such as a sponge detachably mounted on the inner surface part of the mask; a filter detachably mounted on the outer surface part of the mask, the filter being impregnated in Chitosan, Bio-ceramic or active carbon or molded only with Chitosan for absorbing, filtering, sterilizing and disinfecting the outside air and destroying insects; and an ad-
vertising plate for protecting the filter and providing an advertising effect. Advantageous Effects
[7] As described above, when the user wears the mask according to the present invention, the expandable flaps 6, 6' and 6", mounted on the right and left sides and the lower end of the mask body 1 is pulled out by expansion force of the expandable connection part 8, so that the mask is in close contact with the user's face and the face contacting members 10, 10' and 10" of the inner surface part la of the mask body 1 are controlled in their position according to the user's facial shape and size, whereby the present invention can prevent entering of the outside air. Furthermore, since the right and left expandable flaps 6 and 6' respectively have the plate type magnets 24 and 24' buried in the center thereof, the present invention promotes the blood circulation of the user's face. Additionally, the present invention is sanitary and keeps warm since the filter 12 impregnated in Chitosan, Bio-ceramic or active carbon and the multiple reinforcing pieces 4 can absorb, filter, disinfect and sterilize the polluted air. In addition, the present invention provides an advertising effect by the advertising plate 21 detachably mounted on the mask cover 20.

[18] Best Mode for Carrying Out the Invention
[19] Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
[20] A mask according to the present invention includes a mask body 1 made of woven fabric of two to four folds and ear strings 2 mounted on four edges of the mask body 1. An inner part la of the mask body 1 includes multiple reinforcing pieces 4 sewed on a breathing part 3 of the center thereof and made of woven fabric or non-woven fabric of many folds, expandable flaps 6 and 6' sewed and fixed at right and left ends of the mask body 1 and expandably supported by expandable strings 5, plate type magnets 24 and 24' respectively buried in the center of the expandable flaps 6 and 6' expandable flaps 7 and 7' sewed on the lower end of the mask body 1 and expanding by a expandable connection part 8, and a number of Velcro tapes 9' detachably adhered around the breathing part 3 of the center of the mask body 1 and corresponding to a number of Velcro tapes 9' adhered on arc-shaped or "-"shaped face contacting members 10, 10' and 10" An outer surface part lb of the mask body 1 includes: a T- shaped elastic fixing part 11 sewed and fixed on the breathing part 3 of the center thereof; "-"-shaped and 'T'-shaped Velcro tapes 16 adhered on both sides and the upper portion of the outer surface part lb of the mask body 1; and a soft filter 12 such as a sponge detachably fixed on the T-shaped elastic fixing part 11 and having a filter body 12a, which has a supporting portion 13 formed at the center thereof, division pieces 12b' detachably fixed on division recesses 14a and 14b formed at both sides of the filter body 12a, a filter cover 12c detachably fixed in such a way as to surround the division pieces 12b' and the filter body 12a, and a central supporting piece 12d detachably fixed on an expandable groove 15 formed in the center of the filter cover 12c, the filter 12 being impregnated in Chitosan, Bio-ceramic or active carbon or molded only with Chitosan. A lower end 23' of an inner surface part 20a of a mask cover 20 is sewed and fixed on a lower end 23 o the outer surface art lb of the mask bodyl. The mask cover 20 includes: elastic fixing parts 17 and 17' attached to the inner and outer surfaces thereof, the elastic fixing parts 17 and 17' being equal to the T- shaped elastic fixing part 11; a number of Velcro tapes 16' adhered on both sides and the upper portion of the inner part 20a thereof and corresponding to the Velcro tapes 16 adhered on the outer part lb of the mask body 1; and elongated elastic cords 19 and 19' mounted on both sides of the upper portion thereof. The elastic fixing part 17' of the outer surface part 20b of the mask cover 20 has a combined elastic fixing part cover and advertising plate 21 detachably mounted on the elastic fixing part 17' of an outer surface part 20b of the mask cover 20 by Velcro tapes 22 and 22', the combined elastic fixing part cover and advertising plate 21 having a "n" shaped side- sectional view.
[21] In the functional mask according to the present invention, since the breathing part 3 of the center of the inner surface part la of the mask body 1 has the multiple reinforcing pieces 4 made of woven fabric or non- woven fabric of many folds, most air
pollutants and cool air are intercepted and filtered. Furthermore, since the face contacting members 10, 10' and 10" can be detachably attached at a proper position around the breathing part 3 according to a user's face size and shape by means of the Velcro tapes 9 and 9', when the user wears the mask, the inner surface part la of the mask body 1 is in contact with the user's face by the face contacting members, so that the outside air cannot enter in all directions of the inner surface part la of the mask body 1. Particularly, when the user wears the mask in the winter season, since the upper end bended portion of the right and left face contacting members 10 and 10' of the inner surface part la of the mask body 1 is in close contact with the outer surface of the user's nose, the steam of breath cannot ascend to the upper portion of the mask, so that the present invention can prevent the user's eyeglasses from being frosted. Moreover, since the right and left expandable flaps 6 and 6' of the mask body 1 is fixed to the ear strings 2 by the expandable strings 5 and the expandable flaps 7 and 7' of the lower portion of the mask body 1 is fixed to the expandable connection part 8, when the user wears the mask, the right and left expandable flaps 6 and 6' are expanded by the expandable strings 5 connected to the ear strings 2, closely contact to the user's side face, and promote blood circulation of the user's face by the plate type magnets 24 and 24' buried in the center of the expandable flaps. Since the magnets 24 and 24' are faced and attached with each other when the mask is not used, the mask is not polluted when the mask is folded, thereby providing easiness in safe-keeping. The expandable flaps 7 and 7' of the lower end of the mask body 1 are expanded by the expandable connection part 8 disposed at the center of the mask body and closely contact with the user's chin. So, the present invention can protect the user's all facial parts, keep the use's face warm, and completely prevent cool air and polluted air. [22] Furthermore, the mask 1 has the T-shaped elastic fixing part attached on the outer surface part lb thereof. When the filter 12 which is impregnated in Chitosan, Bio- ceramic or active carbon or molded only with Chitosan, is inserted and fixed to the T- shaped elastic fixing part 11, the functional mask according to the present invention can absorb, filter, disinfect, sterilize and remove the outside polluted air by the filter 12, which impregnated in Chitosan, Bio-ceramic or active carbon or molded only with Chitosan. In addition, since the filter 12 is made of soft material such as the sponge so as to be freely bended when the mask is folded or bended and the filter body 12a is divided into two, the filter body 12a is easily bended at the supporting portion 13 of the center thereof, so that the division pieces 12b' detachably mounted on the division recesses 14a and 14b can freely and laterally move from the supporting portion 13 but not be separated from the filter body 12a. Furthermore, the division pieces 12b' and the filter body 12a are surrounded by the filter cover 12c and freely and laterally move in a mounted state without separation by the expandable groove 15 of the center of the
filter cover 12c and the central supporting piece 12d detachably fixed to the expandable groove 15, so that the filter 12 can be freely folded and unfolded when the mask body 1 is folded.
[23] Moreover, to cover the outer surface part lb of the mask body 1 to which the filter 12 is detachably mounted, when the Velcro tapes 16' adhered on the mask cover 20 sewed and fixed to the lower end of the outer surface part lb and the Velcro tapes 16 adhered on the outer surface part lb of the mask body 1 are attached to each other so as to the inner surface part 20a of the mask cover 20 is in close contact with the outer surface part lb of the mask body 1, the filter 12 and the T-shaped elastic fixing part 11 are hided and only the T-shaped elastic fixing part 17' mounted on the outer surface part 20b of the cover 20 is shown. At this time, the elongated elastic cords 19 and 19' mounted on both sides of the upper end of the mask cover 20 is folded into the inner surface part la of the mask body 1 in a state where the mask cover 20 is fixed to the outer surface part lb of the mask body 1 when the user wears the mask. Then, the ends of the elongated elastic cords 19 and 19' are fit inserted and fixed between the Velcro tapes 9 and 9' of the face contacting members 10, 10' and 10" attached by the Velcro tapes 9 and 9' without separation from the Velcro tapes 9 and 9' so as to provide good outward appearance. Advertising letters or animation can be applied to the outer surface part 20b o the mask cover 20. Additionally, to hide the elastic fixing part 17' of the outer surface part 20b, the n-shaped advertising plate 21 which serves as the elastic fixing part cover is attached to the elastic fixing part 17', so that the advertising plate 21 can advertise by the letters or animation without exposing the T-shaped elastic fixing part to the outside. Moreover, another filter may be inserted into the T-shaped elastic fixing part 17 mounted on the inner surface of the mask cover 20.
[24] Industrial Applicability
[25] As described above, when the user wears the mask according to the present invention, the expandable flaps 6, 6', 7 and 7' mounted on the right and left sides and the lower end of the mask body 1 is pulled out by expansion force of the expandable connection part 8, so that the mask is in close contact with the user's face and the face contacting members 10, 10' and 10" of the inner surface part la of the mask body 1 are controlled in their position according to the user's facial shape and size, whereby the present invention can prevent entering of the outside air. Furthermore, since the right and left expandable flaps 6 and 6' respectively have the plate type magnets 24 and 24" buried in the center thereof, the present invention promotes the blood circulation of the user's face. Additionally, the present invention is sanitary and keeps warm since the filter 12 impregnated in Chitosan, Bio-ceramic or active carbon and the multiple re-
inforcing pieces 4 can absorb, filter, disinfect and sterilize the polluted air. In addition, the present invention provides an advertising effect by the advertising plate 21 detachably mounted on the mask cover 20.
