Description

Mask for changing film

A mask for covering the mouth and nose of a human body to block externally polluted air, in particular, a mask including a virtual edge film is more closely attached to the face, and has a replaceable and fixed filtered filter. The structure of the film.

Prosperous industrial and commercial society has developed air pollution. Fast and convenient transportation has accelerated the spread of bacteria and viruses. In addition, various weathers, such as the greenhouse effect, have caused many problems and nightmares in human life, but the oxygen in the air is necessary for the human body to sustain life. Therefore, in order to block bacteria and viruses in the air, people wear masks on their faces to cover the nose and mouth to filter the pollution sources in the air and inhale the fresh air.

The masks commonly used in the market today are made of cotton yarn, which has a rectangular shape and a plurality of transverse wrinkles, and a rigid strip that can be concavely folded near the middle of the nose. In use, the cotton cords on both sides are hung on the ears, and the transverse wrinkles are respectively spread out in the direction of the nose and the chin to cover the nose and mouth of the user, and then the concave strips are used to fit the user. In the shape of the bridge of the nose, although such masks are widely used, there are the following defects that need improvement.

When the weather is cold, if such a mask is used to keep warm, under long-term use, the water vapor exhaled in the mouth gradually expands the cotton fiber, so that the airflow in the mask cannot be circulated, and the user feels wet and uncomfortable. Even in colder areas, even frost may form. phenomenon. Moreover, the human mouth is grown up and down instead of left and right, so the rectangular shape of the mask cannot naturally conform to the face, and it needs to rely on the lateral wrinkles to fully cover the nose and mouth, which is inconvenient to use, and The gap between the wrinkles is easy for bacteria and viruses to enter. Finally, the hard strips used to match the nose of different users are also easy to fit completely with the bridge of the nose. The gap between the two is also easy for bacteria and viruses to get into the gap.

In addition, there are other masks for various functions on the market. Although different functional masks can achieve different functions, if the user needs to use masks for each function, it is conceivable that the money spent on purchasing masks will be large. increase.

The purpose of this creation is to solve various problems caused by conventional masks, and to provide a mask with a replaceable filter and a virtual edge film, which can be closer to the human face and effectively prevent bacteria and viruses from entering the gap. An efficient way to isolate the source of pollution.

The structure for achieving the above object comprises: a cover body composed of two pieces, one end side of which is connected to each other as a closed end side, and the other end is an open end side, and the appearance of the piece body is The closed end edge is gradually curved toward the open end edge, and the sheet body is provided with a hanging structure at the open end side thereof, and the first surface of the sheet body can cover the human mouth and nose after the sheet body is unfolded; Provided in a floating manner along a peripheral edge of the first face of the cover; at least one fixing structure disposed on the first face of the cover and disposed not to extend beyond the virtual edge film structure; and a filter The fixing structure is disposed on the first side of the cover.

In a preferred embodiment, the fixing structure is at least one string, and the two ends of the string are connected to the cover body, and the filter piece is provided with at least two notches, and is disposed on the string via the string. The recess is fixed to the first side of the cover.

In another preferred embodiment, when the filter is small in area, it is disposed at a central portion of the cover via a fixing structure, and when the filter is large in area, is disposed through three fixed structures. The cover is comprehensive.

The filter sheet in the above different embodiments may be a fine non-woven fabric, a heat-generating fiber filter sheet, an activated carbon filter sheet, a nano-bamboo carbon filter sheet or a polyester fiber filter sheet. Among them, the filter sheet of the heat-generating fiber material is lighter and softer, and can absorb the sweat and moisture emitted by the human skin to be converted into heat energy, thereby achieving the warmth effect; the activated carbon material filter can filter fine bacteria and adsorb organic gas and foul smell. Toxic dust and other contaminants; Nano bamboo carbon filter can absorb sweat and deodorize, and prevent infrared rays; polyester fiber can quickly discharge sweat by capillary phenomenon and evaporation.

This design utilizes the above-mentioned structure and various materials to implement filters of different sizes and sizes. The purpose is to be able to change the filter at any time, depending on the air quality of the environment or the temperature and temperature, so that the filter can be quickly replaced in any case. Under the present, this mask can be used for the purpose. There are more advantages than the conventional masks described below.

The cover body is formed by two sheets, so that the opening and closing structure similar to the clamshell shape is more easily adhered to the human face, and the appearance of the two pieces is gradually reduced from the closed end edge to the open end edge, so that the shape is reduced. The creation can naturally cover the nose and mouth of the human body, and the inner space of the cover body is wider than the conventional mask, so that the air is circulated smoothly inside the cover body, thereby solving the problem that the conventional mask is prone to suffocation if it is used for a long time. .

The creation uses a film structure to combine the cover body, so that the mask can be closely combined with the face from beginning to end. The principle is as follows: when inhaling, the pressure inside the cover body is small, and the external pressure is large, and the film structure is externally pressed. Apply pressure inside the body, so that the cover can be tighter On the face; when exhaling, the pressure inside the cover is large, the external pressure is small, the cover will naturally expand and rise, but the mask is made of breathable leaking material, so the thrust cannot be continued upward, and the film is attached and The cover is combined to form a virtual edge film inward, so that it is impossible to leave the cheek from beginning to end. It’s just a little tighter on the cheek, or a little looser, but it’s always in close contact.

The creation utilizes a fixed structure and a filter of various functions, so that the user can use the functions of the various filters only by using the creation, thereby reducing the cost of the user to purchase different functional masks, wherein the filter is formed. The area is one-sixth to one-quarter of the material used in conventional masks, which is very economical. In addition, the area of the filter can be made large or small. In winter, the filter piece with larger area can be used for warmth. In summer, the filter piece with smaller area can be used for ventilation, so that users can enjoy it in different seasons. Use this creation. Finally, this creation can easily change the filter of different functions at any time by using a cover. When the filter is unusable, simply discard the filter and immediately replace it with a new filter. The cover can continue to be used. . However, it has to be discarded after several changes. However, it has been used for a longer period of time than the conventional masks. It is in line with the environmental protection needs of today's energy saving and carbon reduction.
