Description

An air filter mask

technical field

The utility model mainly relates to the field of air filtering masks, in particular to an air filtering mask which can be equipped with pleated non-woven fabric and has filtering ability.

Background technique

Most of the masks used for air filtration are multi-layer non-woven fabrics or multi-layer cotton yarns, and some are even put into use without electrostatic treatment, which has the disadvantages of insufficient cleaning power and weak purification ability. Because the dust cannot be stored or placed, it blocks the ventilation holes, causing the air filter mask to fail in a short time, especially in dusty places. Air filter masks are a guarantee for the health of the human respiratory tract. Excessive dust and exhaust gas inhaled into the human body will affect the health of the respiratory system. The air filter mask is a practical product that filters the dust particles in the outside air to ensure the cleanliness of the respiratory system. On the basis of the existing air filter mask, through improvement, two layers of pleated non-woven fabrics with electrostatic treatment (better dust absorption performance) are added to the inner layer of the mask to filter air more effectively.

Contents of the invention

The utility model aims at solving the above-mentioned problems, and provides an air filter mask with improved air filter degree. It is achieved through the following technical content:

An air filter mask, comprising an outer cover layer, a filter layer, an inner membrane layer, a bridge of the nose, and ear hooks, the filter layer (2) is a two-layer pleated structure; a gap (3) is left in the middle of the two-layer pleated structure .

Compared with the prior art, the utility model has the following advantages:

1. The outer cover layer is to isolate the large particles of dust in the air and filter the air slightly. The main filter layer is the main place for air filtration. Two layers of electrostatically treated pleated non-woven fabrics are placed opposite to each other to effectively improve the dust absorption capacity and filtration degree of the mask.

2. Since the two layers of electrostatically treated pleated non-woven fabrics are placed in opposition, the middle gap can store the adsorbed and filtered dust, avoiding the main filter layer from reducing the purification capacity due to too much dust adhesion, and avoiding the use of Or because the dust adhesion of the main filter layer reduces the air passage gap and hinders breathing, thereby prolonging the service life of the mask.

3. The inner membrane layer uses ordinary electrostatically treated non-woven fabrics to filter the air filtered by the outer cover layer and the main filter layer again, so that the air entering the human body can be well filtered, and because the non-woven fabrics are moisture-proof and breathable , flexible, light weight, non-toxic and non-irritating, and the pleated design has good air permeability, and the human body will not feel depressed or other discomforts.

4. Add a week of nasal bridge around the mask to make the mask contact with the face more closely, prevent air leakage and ensure smooth breathing.

Description of drawings

Fig. 1 is a schematic diagram of the appearance of the utility model;

Fig. 2 is a sectional view of the utility model (without beam bars and ear hooks).

Specific implementation method

1. Outer cover layer; 2. Filter layer; 3. Gap; 4. Intima layer; 5. Nasal tendon; 6. Ear hook.

Below in conjunction with accompanying drawing, the utility model is further described:

The utility model comprises the outer cover layer (1), the bridge of the nose (5), the ear hook (6) in Fig. 1, the filter layer (2), the gap (3) and the intima layer (4) in Fig. 2 . Referring to Fig. 2 is a kind of embodiment of the utility model air filter mouth mask, when the air passes through the outer cover layer, the larger dust impurities of the particles are filtered out, and the tiny particles still enter the filter layer with the air, and the pleated filter layer structure makes the air and filter material As the contact area increases, the frictional resistance between tiny particles and the filter layer also increases, thus being trapped in the gap between the two layers of pleated structures. The air filtered by the double layer enters the human respiratory tract through the slight filtration of the inner membrane layer. The filtered dust falls in the gap between the two pleated filter layers.

Claims (1)

1. an air filter type mouth mask comprises enclosing cover layer, filter course, theca interna, bridge of the nose muscle, ear-hang, it is characterized in that: described filter course (2) is two-layer pleat shape structure; Leave gap (3) in the middle of the two-layer pleat shape structure.
