Abstract
The utility model relates to a separation type emergency mask for preventing against chemical agent. The separation type emergency mask for preventing against chemical agent is composed of a mask, right and left filter paper, an air suction tank arranged between the bottom plate and a smoke inlet closed plate with an air inlet hole, an eye mask, an air suction pipe and a head cover, wherein, the filter paper arranged in the right and the left air suction tanks is designed into a tooth shape; the filtering material of both ends is positioned by flat screw pressing springs; both sides of the outside of the flat screw pressing springs are respectively positioned by an air inlet pressing plate with press strips; the air inlet pressing plate is provided with air holes; one side of the air inlet pressing plate is sealed and fixed by an air passage block, and the other side is compressed tightly by applying a definite compressive force; the other end of the spring is positioned by the smoke inlet closed plate with an air inlet hole; the left and the right air suction tanks are packaged by an aluminium casing.
Description
Provided by the utility model is the emergent breathing mask of a kind of separate type, belongs to the lifesaving appliance field in human lives's needs.
Breathing mask in the prior art background, as Chinese patent 96229337.7, it is comparatively ideal breathing mask, but in actual use, especially uses in the environment of inclement condition, also has the not enough and high temperature resistant defect of insufficient of Air permenbility.
The purpose of this utility model has been to overcome the defective that exists in the prior art background, has especially structurally adopted some corrective measures, has overcome deficiency of the prior art preferably.
Content of the present utility model mainly is to relate to the emergent breathing mask of a kind of separate type, in order to strengthen filter tolerance, improved the air-breathing jar of internal structure design in the former left and right sides, filter paper is designed to the profile of tooth filter paper is located by flat silk stage clip respectively at the two ends of filtering material, both sides, the flat silk stage clip outside are respectively by the air inlet pressing plate location that has press strip, one side of air inlet pressing plate is sealed fixing by the air channel piece, opposite side applies certain pressure by spring and compresses, the pressure of spring is compressed in duty effectively reliably with filtering material, and the other end of spring is located by the cigarette shrouding that advances that has air admission hole.In order to improve high-temperature resistance, on the air-breathing jar in the former left and right sides, be designed to form by the aluminum shell parcel.
The utility model is obvious through improving design effect, and air-breathing jar inspiratory capacity has more than tripled, but the air-breathing jar of high temperature resistance in the left and right sides reaches 800 ℃.
Below with reference to accompanying drawing so that technical characterictic of the present utility model is described in detail:
Fig. 1 front schematic view of the present utility model
Schematic diagram cuts open in Fig. 2 air-breathing jar of office of the present utility model
Fig. 3 profile of tooth filter paper structural representation
As shown in Figure 1 and Figure 2, the utility model mainly is made of mouth mask 1, air-breathing jar 2 on a left side, right air-breathing jar 3, eyeshade 4, air intake duct 5 and head-shield 6, be respectively equipped with filter paper in the air-breathing jar 2,3 in the left and right sides, in order to increase Air permenbility, improve the air inflow of filtering gas, filter paper is designed to profile of tooth filter paper 7, and profile of tooth filter paper 7 is arranged on base plate 14 and has the advancing between the cigarette shrouding 15 of air admission hole.The two ends of filtering material 9 are by flat silk stage clip 10 location, flat silk both sides, stage clip 10 outside are respectively by air inlet pressing plate 12 location that have press strip 11, offer pore on the air inlet pressing plate 12, the one side is sealed fixing by air channel piece 13, opposite side applies certain pressure by spring 16 and compresses, and the other end of spring 16 is by entering cigarette shrouding 15 location.In order further to improve the ability of high temperature resistance of the present utility model, the left and right sides is designed to for air-breathing jar 2,3 be formed by aluminum shell 8 parcels.
