Abstract
The utility model relates to a respirator which can ensure that people can normally breathe pollution-free air when working in the environment polluted by harmful substances such as dust, smog and the like, thereby effectively protecting the human health. The respirator forms a filtering space (2) between a polluted air inlet hole (4) and a purified air suction hole (3) of a face mask (1), an air purifying and filtering device (5) is arranged in the filtering space, and a liquid-gas injection pipe (7) is communicated with the filtering space (2) through a connector (6). The method can be widely applied to various industries with smoke and toxic gas pollution, such as mining, building materials, chemical industry and the like, and has great labor protection value and social significance.
Description
The utility model relates to a kind of respirator of practicality, when it makes people work or live in the environment that dust, smog and other harmful substance are polluted, can arrive free of contamination air by eupnea, thereby can protect health effectively.
All there is the material such as flue dust, poison gas of a large amount of serious harm healths the work-yard of many industries (as mining, building materials, chemical industry etc.) in the air, make the people that are operated in this environment suffer from various occupational diseases, even jeopardize people's life.In order to alleviate the infringement of these harmful flue dust, be extensive use of a kind of dust mask at present, the simple filtration effect by dust mask reaches the purpose that purifies air to a certain extent, but poor effect, the air that sucks human body still contains a large amount of harmful substances.
Task of the present utility model provides a kind of respirator of practicality, when it makes people work or live in the environment that harmful substances such as flue dust are polluted, can eupnea to free of contamination air, thereby can protect health effectively.
Task of the present utility model is achieved in that respirator forms by face shield with the fixture that face shield is fixed on head, set contaminated air enters the hole and purifies air and constituted filter space between the inlet hole on the face shield, in this space, be provided with air filter, face shield is provided with interface, and liquid gas ascending pipe is communicated with filter space by this interface.Under the condition of no air feed or oxygen supply, can in filter space, inject water or thimerosal etc. at any time by liquid gas ascending pipe, the flushing out air filtration equipment for clarifying also makes it to keep moistening, and wet type filter dirt or filter poison reach the purpose that efficiently purifies air; And under the condition that air feed or oxygen supply are arranged, only need in face shield, import gases such as fresh air, oxygen by liquid gas ascending pipe, can guarantee to suck in the air of human body pollution-free.
The respirator that the utility model proposes; because only form by parts seldom such as face shield, face shield fixture, air purification filter device, liquid gas ascending pipes; structure is very simple; cost is also low; need only during use according to having or not the air feed oxygen supply condition; connect liquid injection pipe or air injection pipe; with cover on the face shield Dai Yutou mouthful, nose gets final product; event is produced and is used this respirator all to be easy to; small investment; the effective utilization height, of many uses, special meaning and value at aspects such as labour protection, the protection of breathing problem infected area is very huge.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is according to the respirator side view that the utility model proposes.
Below in conjunction with Fig. 1, describe details and operating position in detail according to the concrete respirator that the utility model proposes.
The face shield of this respirator (1) is provided with contaminated air and enters hole (4), be provided with the inlet hole that purifies air (3) in the face shield (1), enter between hole (4) and the inlet hole (3) and constituted filter space (2), in this space, be provided with air purification filter device (5), face shield (1) is provided with interface (6), and liquid gas ascending pipe (7) is communicated with filter space (2) by interface (6).
According to air-polluting heterogeneity, the filtrate in the air purification filter device (5) is also different.When air-polluting material is dust, general smog, can adopt filtrate such as gauze, cotton or hair to be arranged in the filter space (2); When air-polluting material is toxic gas, can adopt filtrate such as active carbon to be arranged in the filter space (2).
For purifying, filter contaminated air efficiently, liquid gas ascending pipe (7) is communicated with by the interior filter space (2) of interface (6) and face shield (1), at any time water filling in filter space (2), washing and filtering device (5) also makes filtrate keep moistening, and wet purification filters contaminated air.When air includes noxious material, can inject in the filter space (2) with thimerosal according to the character of contaminated air.
If any air feed, oxygen supply condition, ventilation, air line are for example arranged in the work-yard, or oxygen cylinder etc. is arranged, can in filter space (2), inject gases such as fresh air or oxygen by liquid gas ascending pipe (7).
For getting rid of the waste gas that human body is breathed out better, and can converse with others, be provided with in face shield (1) and exhale and communicator (8), this device is a cage, can be fixed in oral area, is provided with exhaling hole, with the external communications of face shield (1).
The device (9) that respirator is fixed in head is that Ah, also can realize respirator is fixed in the purpose of head with respirator and safety cap or common cap as one with frenulum generally.
Claims (4)
1; a kind ofly make people at dust; when working or living in the environment that harmful substances such as smog are polluted; can arrive free of contamination air by eupnea; thereby can protect the respirator of health effectively; by cover (1) with will cover the fixture (9) that (1) be fixed on head and form; it is characterized in that cover (1) is provided with contaminated air and enters hole (4) and the inlet hole that purifies air (3); enter between hole (4) and the inlet hole (3) and constitute filter space (2); in this space (2), be provided with air purification filter device (5); cover (1) is provided with interface (6), and liquid gas ascending pipe (7) is communicated with filter space (2) by interface (6).
2, respirator according to claim 1 is characterized in that air purification filter device (5) adopts hair to be arranged at filter space (2) Inner as filtrate.
3, respirator according to claim 1 is characterized in that air purification filter device (5) is that the toxic dust filtrate of using always is arranged in the filter space (2).
4, respirator according to claim 1 is characterized in that also being provided with in the cover (1) and exhales and communicator (8), and this device can be a cage, can be fixed in oral area, is provided with exhaling hole and cover (1) external communications.
