Description

A kind of laboratory anti-bacterial mask

technical field

The utility model relates to a mask, in particular to a laboratory antibacterial mask.

Background technique

When engaged in scientific research in the laboratory, wearing a mask has a very good protective effect, which can prevent bacteria, dust, harmful gases, and unpleasant odors from entering the human body through the nasal cavity, thereby avoiding harm to the human body. However, although the traditional mask has a strong adsorption effect on dust and the like, it has a weak protective effect on bacteria and cannot meet health protection measures.

Metal silver complexes have good antibacterial effect and good chemical stability. Using metal silver complexes in mask design can not only absorb harmful gases, but also have good antibacterial effect.

Due to the existence of the above-mentioned problems, the inventor designs a kind of laboratory antibacterial mouth mask containing metal-silver complex.

Contents of the invention

The purpose of this utility model invention is to provide a kind of mouth mask for laboratory anti-bacteria.

The purpose of the invention of the utility model is achieved through the following technical measures: a laboratory anti-bacterial mask, comprising a mask body, a metal-silver complex layer, an active carbon layer, a mask band, a fixing strip and an elastic band.

The mask body is made of non-woven fabric, and cotton material can be added to the inner layer on the side of the wearer's face to increase the comfort of the face. The mask body can filter large particles and fine dust in the environment.

The second layer of the mask is a metal-silver complex layer, which can be made into a moderate particle size and evenly distributed in the non-woven layer to kill bacteria entering the nasal cavity.

The third layer of the mask is the activated carbon layer. The activated carbon is placed in the non-woven fabric. The activated carbon particles are uniform in size and can be set as multiple folds spaced apart from each other to increase the specific surface area of the activated carbon and further prevent harmful gases that are not filtered and adsorbed by the second layer. adsorption and removal.

The mask strap is made of elastic material, and there is a mask strap on both sides of the mask.

Furthermore, in order to make the mask fully contact with the wearer's face and achieve real antibacterial protection, a fixing strip with an inner layer of aluminum and an outer layer of PP plastic is installed above the mask, which can be pressed down gently according to the size of the bridge of the wearer's nose to ensure The upper edge of the mask is in full contact with the wearer's face.

Further, elastic belts are installed on the left and right sides of the mask to ensure that the side of the mask is in full contact with the wearer's face without air leakage.

The working principle and working process of the utility model are as follows: a laboratory anti-bacterial mask, the non-woven layer of the mask body can filter and block large particles of dust in the environment from entering the human body through the nasal cavity; the second layer of metal silver complex layer It can kill the bacteria entering the nasal cavity and play an antibacterial effect; the third layer of activated carbon can further absorb and remove the harmful gases that have not been filtered and absorbed by the second layer; the inner layer above the mask is aluminum sheet, the outer layer The layer is a PP plastic fixing strip, which can be gently pressed according to the size of the bridge of the wearer's nose to ensure that the upper edge of the mask is in full contact with the wearer's face; the elastic bands on the left and right sides of the mask can ensure that the side of the mask is in contact with the wearer's face Full contact without leaking.

The beneficial effects of the utility model are: a laboratory antibacterial mask proposed by the present invention has good antibacterial effect, has the functions of filtering and blocking dust, killing bacteria and removing harmful gases, and is suitable for laboratory workers to wear, and its structure is simple , reasonable in design, low in cost, easy to manufacture, and has broad market prospects.

detailed description

The utility model will be further described below in conjunction with specific embodiments. It should be noted that the accompanying drawings of the present invention are all in simplified form and use inaccurate proportions, and are only used to facilitate and clearly illustrate the purpose of implementing the utility model. .

As shown in Fig. 1, a kind of laboratory antibacterial mask provided by the utility model comprises a mask body 1, a metal-silver complex layer 2, an activated carbon layer 3, a mask belt 4, a fixing strip 5 and an elastic belt 6.

In this embodiment, the mask body 1 is made of non-woven fabric, and the inner layer can be added with cotton material on the side of the wearer's face to increase the comfort of the face, and the mask body can filter large particles of dust in the environment Wait.

In this embodiment, the metal silver complex layer 2 is composed of a metal silver complex layer and a non-woven fabric, the metal silver complex layer is placed in the non-woven fabric, the particle size of the metal silver complex is uniform, and the metal silver complex The layer is made into a plurality of folds spaced apart from each other in the non-woven fabric, so as to increase the antibacterial and adsorption capacity of the metal-silver complex layer.
