Description

Sanitary mask with built-in composite filter {A HEALTH MASK HAVE A COMPOUND FILTERS}

The present invention relates to a portable mask incorporating a composite filter.

General sanitary masks are relatively widely used because of their simple structure, light weight, and ease of carrying and wearing. However, sanitary masks are made of layered fabric or non-woven fabrics, and they do not have high filtration functions such as gas masks, so they have poor filtration even when wearing masks in fire areas such as subway stations or in areas with extreme dust or air pollution. It was difficult to protect the respiratory organs of the human body.

The filtration function of the conventional portable mask is further improved, and some examples of the prior art of the mask are as follows.

① "Hygiene mask using natural scrubber" of Utility Model Registration No. 271681 (registered on Mar. 29, 2002) is a snorkel produced when breathing with scrubber embedded inside a rectangular mask body made of ordinary cotton. Although it can absorb moisture of breathing, but the filtration function of scrubbers is primitive, there is almost no filtration function such as external fine dust, odor and harmful gas.

(2) "Mask with moisture absorption / dustproof / deodorization function" of Utility Model Registration No. 187062 (registered on April 14, 2000) is that an activated carbon filtration member is fixed by a coupling member inside a mask body made of cotton or cloth. The activated carbon filter has the ability to adsorb and remove some of the gas, but it does not have the function of removing antibacterial or charged dust.

③ "Mask using silver fiber activated carbon" of Utility Model Registration No. 284415 (registered on July 23, 2002) is a filter material of silver fiber activated carbon embedded in the mask body. It is equipped with the ability to adsorb, but due to the structure of the mask is insufficient sealing of the nose and mouth part can not block the inflow of outside air and the filtration function of activated carbon is not different from the prior art of ②.

④ The "dust filter mask filter material" of Utility Model Registration No. 278590 (registered on Jun. 03, 2002) is a filter filter layer made of non-woven fabric inside the upper and lower filter material layers, and an electrostatic filter layer made of fibers spun by mixing polypropylene and modacryl. It is formed by laminating a double layer, and the laminated filter material of the filtration filter layer and the electrostatic filter layer is applied to the general mask, and there is a characteristic that can remove the fine dust, but there are inadequate points that the filtration and antibacterial action of harmful gases such as gas masks are not considered.

In addition, the masks of the prior art described above are mostly the level of simple rectangular forge or cloth simple masks having a single filter medium, and even when these masks are used, the area of toxic gas diffusion, air pollution and dust are severe. In the region, there is a problem that the safety of the filtration function is insufficient to withstand only one minute.

The present invention relates to a sanitary mask with a built-in composite filter, and intakes a composite filter consisting of a pre-filter, an antibacterial filter, an electrostatic filter, an activated carbon filter, and a rear filter in which titanium dioxide powder is applied to the surface of a filter case in which a vent is formed. The valve is formed by combining the diaphragm with the diaphragm and the mask cover formed with the breathing hole and the exhaust valve at the inner end of the filter case.

The mask of the present invention can maintain the filtration function when breathing because the composite filter is safely protected by the filter case when worn.

In addition, the prefilter coated with titanium dioxide of the composite filter decomposes harmful gases by photocatalytic action, suppresses the growth of fungi and bacteria, has antibacterial function by the antibacterial filter, and has an electric charge by the electrostatic filter. It isolates between co-antibacterial filter which adsorbs fine dust and activated carbon, and can suppress the invasion of bacteria. In addition, the activated carbon particles can be filtered and adsorbed odor and harmful gas by the activated carbon filter in which the three-dimensional pores are maintained in the receptive medium, and the rear filter can finally enhance the filtration function. This filtering capacity exceeds the gas mask level.

Although the rectangular mask has been described in the present invention, the mask is not limited to the rectangular mask, and various types of masks such as a shell shape, diamond type, and an oval can be configured.

When the mask of the present invention is inhaled, the filtered air through the composite filter is sucked into the inlet through the intake valve when inhaling the air, and the intake valve is closed while the exhaled air is opened, and the exhaled air is discharged in one direction of the exhaust port. do. The one-way discharge of the respiratory air is suppressed from mixing the carbon dioxide from the body and the filtered air in the filtration chamber, thereby allowing the fresh air to be sucked and preventing the deterioration of the filtration function of the composite filter due to breathing.

In addition, fine dust, bacteria, odors, and harmful gases are filtered, decomposed, and adsorbed by the mask of the present invention, which can prevent respiratory diseases in cities with high air pollution, and prevent colds by preventing the influx of cold viruses. In case of emergency in fire area, hazardous gas diffusion area and dusty area, you can safely avoid danger area without wearing breathing mask by wearing the mask of this invention.

In addition, the mask of the present invention is satisfied with the ease of portability and hygienic use can be used more safely and usefully than the conventional portable mask.

Rubber bands 1e for wearing a mask are connected to the left and right sides of the filter case 1 by suitable connecting means.

The composite filter 2 is an electrostatic filter that electrically adsorbs a prefilter 2a, a nonwoven fabric coated with a titanium dioxide (TiO ₂ ) powder, which is a photocatalyst, and an antimicrobial filter 2b, and charged fine dust. (2c) and activated carbon particles (c) for adsorbing odors and gases are laminated with an activated carbon filter (2d) distributed in a receiving medium (f) such as fibers and a rear filter (2e) for finally filtering fine dust. have.

According to the present invention, the curved portion 4b of the mask 4 is worn in close contact with the front of the face using the rubber band 1e, and the nose and the mouth are breathed through the breathing holes 4a formed in the mask 4. When drinking air, the outside air is filtered by the composite filter (2) and the intake valve (3v) is introduced into the open inlet (3h) through the filtration chamber (a) to breathe. When exhaling, air exhaled through the exhaust port 4h opened at the same time that the exhaust valve 4v formed in the mask 4 is opened at the same time that the intake valve 3v of the intake port 3h is closed by the discharge pressure of the breathing chamber b. To be discharged. By one-way discharge of the respiratory air can breathe fresher air and the composite filter can be prevented from getting wet or deterioration of the filtration function by the breathing.

During the respiration of air, when titanium dioxide coated on the surface of the prefilter 2a of the composite filter 2 receives ultraviolet light in the sunlight, sulfur dioxide, nitrogen oxide gas, etc. are decomposed by photocatalytic action and bacteria are prefiltered. Reproduction at the surface of (2a) is suppressed. In addition, fine dust in the air to be sucked is filtered by the prefilter 2a. In addition, since the antibacterial filter 2b is embedded between the prefilter 2a and the electrostatic filter 2c, propagation is suppressed even when bacteria suspended in the air by the antibacterial filter 2b are implanted in the prefilter. ) And the electrostatic filter 2c prevent contamination by bacteria. The air filtered by the prefilter 2a and the antibacterial filter 2b is adsorbed and filtered fine dust charged by the electrostatic filter 2c. Further, the activated carbon filter 2d adsorbs odors, harmful gases such as sulfurous acid (SO ₂ ) gas and ammonia (NH ₃ ) gas. In addition, fine dust is finally filtered by the rear filter 2e to suck in very clean air.

The portable mask of the present invention is equipped with a diaphragm with a diaphragm in the filter case, and a diaphragm with an intake valve and a mask cover made of an elastic foam resin is easy to protect and breathe easily. The ease of use and the filtering function of the mask are further improved.

In addition, the dust, bacteria, odor, and harmful gases are filtered, decomposed and adsorbed by the composite filter to prevent respiratory diseases in cities with high air pollution and to prevent cold by invading cold viruses.

In addition, since it can be carried at all times, it can protect the human body's respiratory organs safely while avoiding dangerous areas by wearing the mask in the large fire area, harmful gas diffusion area, and dusty area caused by accidental accident. There are various effects such as being useful for the sick.
