Description

Safe respirator

Technical field

The utility model relates to the respirator technical field, relates in particular to a kind of safe respirator that is widely used in agricultural and industry.

Background technology

Existing respirator plays the effect of mouth mask mostly, generally can not effectively intercept small dust granules, pernicious gas and smog and enter the human body respiration organ, although also have respirator and oxygen cylinder or the plenum chamber by the air blast air-supply to be connected, be used for to people's delivering oxygen or air, but in use there is following shortcoming in it: 1, the scope of application is little, generally only suitable indoor and outdoors etc. among a small circle occasion use, spray insecticide peasant and asphalt roadman for distance that do not stop, long moves are not suitable for using; 2, use inconvenient because it lacks the protection to eyes and head, the injury that can not avoid pernicious gas, liquid or solid that the user is caused, therefore, for the workman in construction site and electric welder in use also add band safety cap and goggles; 3, use cost is higher, is unfavorable for popularizing using.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art; a kind of safe respirator is provided; it is simple in structure, reasonable in design, safe and reliable and cost is lower; simultaneously applied widely; can effectively stop dust granules, toxic gas to enter human respiratory; make the operating personnel can breathe fresh air, and then protected health.

For achieving the above object, the technical solution adopted in the utility model is: a kind of safe respirator, comprise the helmet, face shield and the gas exchanger that backs on the body, it is characterized in that: described face shield is installed on the framework of the helmet, described face shield top is provided with goggles, described face shield bottom is provided with respiratory chamber, the described respiratory chamber left and right sides is connected with escape pipe and air inlet pipe respectively, described escape pipe also is connected with gas exchanger with air inlet pipe, described gas exchanger is made up of not connected left chamber and right chamber, wherein the left chamber upper end is connected with escape pipe, described left chamber lower end is provided with exhaust outlet, described left chamber is provided with exhaust fan in the chamber, and described right chamber upper end is connected with air inlet pipe, and described right chamber lower end is provided with breather pipe thicker than air inlet pipe and that lead to the fresh air place.

The discharge air back valve is housed on the described exhaust outlet.

Described gas exchanger top is provided with jack, is inserted with high pole or duroplasts bar in the described jack.

The described gas exchanger left and right sides is provided with braces.

The described respiratory chamber left and right sides is provided with fixed band.

Described goggles and face shield are for removably connecting.

The utility model compared with prior art has the following advantages:

(1) simple in structure, reasonable in design, it is made up of with air inlet pipe and with the gas exchanger that escape pipe is connected with air inlet pipe with the escape pipe that is connected with face shield the face shield that is installed on the helmet;

(2) safe and reliable, can effectively stop dust granules, toxic gas to enter human respiratory, make the operating personnel can breathe fresh air, and then protected health;

(3) use cost is lower, and it can make the people that are in the contaminated environment directly breathe fresh air by breather pipe, and not only dustproof, gas defence and preventing polluting effect are obvious, and have saved use cost;

(4) applied widely, this safe respirator is not only applicable to carpenter, bricklayer, painter and the electric welder etc. of indoor decoration, and be applicable to operating personnel under the ore deposit, also can be used for spray insecticide peasant and asphalt roadman that outdoor long distance does not stop to move simultaneously.
