Description

Dustproof respirator

The utility model is a kind of dustproof respirator, belongs to a kind of technical field of appliances for labor protection.

Existing dustproof breathing equipment structure more complicated, generally be to use oxygen breathing apparatus as breathing usefulness, in many occasions, such as: use in the fields such as mine, smelting, building, can prevent the generation of diseases such as similar anthraco-silicosis, but the cost of this product uses, keeps in repair all inconveniences than higher, so a lot of production occasion is difficult to promote the use of, Min Ban enterprise more particularly, can not use especially, so, influence the healthy of the producer greatly.

The purpose of this utility model is: a kind of dustproof respirator is provided, the structure of this product is simple especially, use, easy to maintenance, cost is also lower, can prevent effectively that noxious air is inhaled in the human body, can prevent the generation of diseases such as anthraco-silicosis, product can also use in environment such as fire-extinguishing and lifesaving, prevents that effectively flue dust from suffocating.

The utility model is to constitute like this: it has a breathing mask (1), drain tap (3), pneumostome (4) are arranged on the breathing mask (1), pneumostome (4) connects an end of respiratory siphon (6), the other end of respiratory siphon (6) is fixed on the lid (7) of dust-filtering kettle (2), water or other liquid are housed in the dust-filtering kettle (2) and fix an air inlet pipe (8), cavity (9) is arranged in the dust-filtering kettle (2), one end of air inlet pipe (8) is fixed on lid (7) and upward is communicated with lid (7) outer air, and the two ends of breathing mask (1) are connected with face shield fixed band (5).

Accompanying drawing 1 is a structural representation of the present utility model, and accompanying drawing 2 is face shield side views of the present utility model.

Compared with prior art: the utility model structure is simple especially, use, easy to maintenance, and cost is also lower, can prevent effectively that noxious air is inhaled in the human body, can prevent the generation of diseases such as anthraco-silicosis, product can also use in environment such as fire-extinguishing and lifesaving, prevents that effectively flue dust from suffocating.

Embodiment 1 of the present utility model: it has a breathing mask (1), drain tap (3) is arranged on the breathing mask (1), pneumostome (4), pneumostome (4) connects an end of respiratory siphon (6), the other end of respiratory siphon (6) is fixed on the lid (7) of dust-filtering kettle (2), water or other liquid are housed in the dust-filtering kettle (2) and fix an air inlet pipe (8), cavity (9) is arranged in the dust-filtering kettle (2), one end of air inlet pipe (8) is fixed on lid (7) and upward is communicated with lid (7) outer air, the two ends of breathing mask (1) are connected with face shield fixed band (5), and this product can prevent dust, Smoke prevention.

Embodiment 2 of the present utility model: it has a breathing mask (1), drain tap (3) is arranged on the breathing mask (1), pneumostome (4), pneumostome (4) connects an end of respiratory siphon (6), the other end of respiratory siphon (6) directly is fixed on the dust-filtering kettle (2), soda water liquid is housed in the dust-filtering kettle (2) and fixes an air inlet pipe (8), be communicated with filter jug (2) outer air, cavity (9) is arranged in the dust-filtering kettle (2), the two ends of breathing mask (1) are connected with face shield fixed band (5), this product can prevent acid toxic gas, as the infringement of sulfur dioxide gas to human body.During use, when human body carries out when air-breathing, fresh air sucks the air in dust-filtering kettle (2) internal cavity by respiratory siphon (6), meanwhile, the drain tap (3) on the breathing mask (1) is closed, when air-breathing end, pressure in the dust-filtering kettle (2) reduces, the outer air of dust-filtering kettle (2) is pressed in the filter jug (2), by the filtration of water or liquid, with air cleaning by air inlet pipe (8) like this; When the human body exhaust, waste gas is washed drain tap (3) open and is got rid of.
