Abstract

The utility model relates to a dust-proof gauze mask. The dust-proof gauze mask is characterized in that two copper screens are arranged inside the mask, and the copper screens are separately connected to the positive and the negative electrodes of a button cell by conducting wires to form an electric field. The two copper screens are respectively provided with positive and negative charges, and the utility model uses the principle that object with homogeneous charge are repellent to each other to exclude harmful matter, such as dust particles, gasoloid, bacteria, viruses, etc. outside to obtain the purposes of dust prevention and filtration.

Description

A kind of anti-dust respirator

The utility model relates to a kind of anti-dust respirator

The utility model and the prior art following advantage of having compared:

Existing mouth mask has two kinds of plain edition and modifieds, and the former all constitutes with gauze, though easy washing simple in structure, dustproof weak effect.The latter is provided with active carbon layer or installs Chinese herbal medicine layer additional or magnetic material is housed in gauze layer, as magnet etc., though increased the adsorption filtration effect, exist complex structure, is not durable, washs shortcomings such as inconvenience.

The purpose of this utility model is at the above-mentioned shortcoming of prior art, proposes the anti-dust respirator of the new structure of a kind of advantages of good adsorption effect, simple in structure, durable, convenient for washing.

Feature of the present utility model is: copper mesh 2 is set between the gauze layer 1 and 3, copper mesh 4 is set between the gauze layer 3 and 5, one end of copper mesh 2 links to each other with an end of lead 7, one end of copper mesh 4 links to each other with an end of lead 8, all carry out at the two ends of copper mesh 2 and copper mesh 4 and to be stamped insulating coating 6, the other end of lead 7 and lead 8 is connected on the both positive and negative polarity Connection Block of button cell box, button cell 11 is contained in the button cell box 10, gauze layer 1,3,5 three seal with line 13, gauze layer 1,5 another side is equipped with slide fastener 12, and fixed band is sewn on gauze layer 1,3, the outside at 5 two ends.

The utility model adopts such scheme, and is both simple in structure, and adapts to different charged dust, good dustproof effect.Can be used as simultaneously common mouth mask when not adding copper mesh uses.

Description of drawings:

Fig. 1 is a structural representation of the present utility model, wherein 6---and insulating coating, 7---lead, 8---lead, 9---fixed band, 10---button such as battery case, 11---button cell, 12---slide fastener, 13---line.

Fig. 2 is the utility model cutaway view, wherein 1---and gauze layer, 2---copper mesh, 3---gauze layer, 4---copper mesh, 5---gauze layer.

Embodiment of the present utility model is described below in conjunction with the accompanying drawings:

After gauze layer 1,3,5 and fixed band 9 usefulness lines 13 were made according to the method for front, its basic structure was similar with common mouth mask.The another side of gauze layer 1,5 is equipped with slide fastener 12, after opening slide fastener 12, between gauze layer 1,3 and gauze layer 3,5, load onto two copper mesh 2 and 4 respectively, the copper mesh two ends are carried out and are stamped insulating coating 6, and at one end link to each other with an end of 8 with lead 7 respectively, the lead 7 and 8 the other end are connected in respectively on the both positive and negative polarity Connection Block of button cell box 10, and button cell 11 is contained in the battery case 10, all be encapsulated in slide fastener 12 on the mouth mask lira, its external form is all the same with common mouth mask with use.But form an electric field owing to power up the back on the copper mesh, two copper mesh are respectively both positive and negative polarity, have positive and negative charge.The utility model will have the dust of electric charge according to having the principle that character electric charge object of the same race repels each other in the air, the purpose that exclusions such as aerosol, bacterium, virus reach is dustproof, improve filter effect.When impurity such as airborne dust have negative electrical charge, the one side that then in use copper mesh in the mouth mask is connected button battery cathode outwardly.When airborne dust had positive charge, the one side that when then using copper mesh is connected the button anode outwardly.

The utility model can take out button cell 11 when not using, and when need cleaning washing, can open slide fastener 12, and two ends are scribbled the copper mesh 2,4 of insulating coating 6, takes out together with lead 7,8 button cell boxes 10, can be cleaned.

Claims

1, a kind of anti-dust respirator is made of gauze layer and fixed band, it is characterized in that: copper mesh 2 is set between the gauze layer 1 and 3, copper mesh 4 is set between the gauze layer 3 and 5, one end of copper mesh 2 links to each other with an end of lead 7, one end of copper mesh 4 links to each other with an end of lead 8, all carry out the insulating coating 6 of lid on the both sides of copper mesh 2 and copper mesh 4, the other end of lead 7 and lead 8 is connected on the both positive and negative polarity Connection Block of button cell box 10, button cell 11 is contained in the button cell box 10, gauze layer 1,3,5 three seal with line 13, gauze layer 1,5 another side is equipped with slide fastener 12, and fixed band 9 is sewn on gauze layer 1,3, the outside at 5 two ends.
