Description

[Detailed description of the invention] The present invention relates to a mask with excellent dustproof and deodorizing effects.

Gauze masks are commonly used, but these alone do not have sufficient antibacterial and deodorizing effects.

In order to compensate for this, products with activated carbon interposed therein are commercially available, but they have problems such as a feeling of use, difficulty in breathing, and poor voice quality.

The present invention is intended to solve such problems, and is designed to reduce the amount of cigarette smoke, dust, etc.
The aim is to provide a product on the market that effectively captures particles down to the micron size, has excellent adsorption properties for organic solvents and bad odors, does not feel like it touches the face, makes breathing easier, and allows for voice to be heard clearly.

An example of implementing the present invention will be described below based on the drawings.

FIG. 1 is an overall perspective view, and FIG. 2 is an exploded view.
Reference numeral 1 denotes a mask main body in which the front and back surfaces 1a and 1b are sewn into a rectangular bag with gauze cloth, and string holes 2a and 2b are formed on both side edges, and an opening is formed on the upper edge. A tongue piece 3 of a certain length is provided from the front side and is designed to be folded into the inside. This allows the stored items to be covered from above, which will be described below, and also prevents them from protruding.

4 is a fine dust filter made of non-woven fibers that can capture cigarette smoke, dust, dust, pollen, etc. down to about 0.5 microns, and 5 is spunbond felt-like P with a certain amount of activated carbon fiber inside. The suction pack 5 has soft metal wires 6, 6' on the upper edge and both side edges to facilitate the retention of the shape that matches the face shape when worn. It is installed.

7 is a frame made of polyurethane foam with a thickness T of approximately 1 cm, and an internal frame with a vertical length of approximately 5 cm and a horizontal length W of approximately 9 cm, making it sized to accommodate the tip of the nose and the vicinity of the lower lip. .

In the present invention, the above components are a fine dust collection filter 4,
The suction pack 5 and the frame 7 are stacked in this order, with the fine dust filter 4 being the front part and the frame 7 being the rear part (face side).
In this way, the mask body 1 is stored in the bag from the open upper side, and the open upper surface is covered with the tongue piece 3. In addition, 8 is an ear hook string.

Therefore, when in use, the rear part of the mask body 1 is placed in contact with the face, and at this time, the upper part of the mask frame 7 comes into contact with the nasal tip and the lower part with the lower lip. Yes, and with the ear straps hanging over your ears, from the front side of the mask body, align the soft metal bar 6 above the suction pack with the height of the nasal tip and fold it slightly inward, as well as The soft metal bar 6' on the side edge is bent toward the buccal side. This allows the mask itself to fit snugly on people with various face shapes, and effectively prevents impurities from entering from around the mask.

In this invention, the activated carbon fiber of the adsorption pack is about 100 times faster at adsorbing organic solvents and bad odors than conventional powdered granular activated carbon, and dirty air can be removed from the front of the mask body using gauze. It passes through 6 layers connected to a fine dust filter, spunbond, activated carbon fiber, spunbond, and gauze, and effectively collects not only pollen (2 microns) but also dust and dirt up to 0.5 microns. It becomes something to do. The mask itself, as well as the fine dust filter and activated carbon fiber, can be washed and replaced at will, allowing for long-term use.

When using this product, the adsorbent on the face side does not come into direct contact with the nose or mouth, and a constant distance is always maintained, making breathing easier. Because the mask is held in a way that fits the shape of the face, there is no feeling of use, the voice comes through easily, and there is no movement restriction in the jaw or mouth, making it an easy-to-use product. At this time,
The window frame dimensions of this frame 7 are approximately 5 cm to 9 cm in length and width, but we have prepared several sizes within this range so that the user can select the appropriate size according to the user. do.
