The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of simple in structure, easy to use, the gas defence box that safety coefficient is high.
The technical solution of the utility model realizes in the following manner, the gas defence box, and its structure is made up of filter cartridge, half mask and headband.
Filter cartridge is a rounded cylindrical, and front end is provided with gas-permeable nets, gas-permeable nets arranged outside coarse filtration core, and its outer end is fixing by the button cover.The sealing plate of rear end is provided with air-breathing seat, and the bilateral symmetry of air-breathing seat is provided with locating convex block, is provided with filter core between gas-permeable nets and the sealing plate.
The half mask front end is provided with circular air-breathing Button Block, and filter cartridge is connected half mask by air-breathing seat with air-breathing Button Block, is provided with and the corresponding detent of locating convex block in the bilateral symmetry of air-breathing Button Block; Air-breathing Button Block below is provided with exhaling hole, is provided with baffle plate between air-breathing Button Block outside half mask and the exhaling hole, in the air-breathing Button Block inlet valve is set, and outlet valve is set in the exhaling hole; The half mask arranged outside has the oronasal mask that meets face's shape, and both sides are provided with bracelet.
The utility model has the advantages that:
1, simple in structure, reasonable in design, volume is little, and is easy to carry, do not influence operation;
2, filter cartridge good airproof performance, the safety coefficient height;
3, filter cartridge is installed simply, easily replaces, and is easy to use.
4, description of drawings
Accompanying drawing 1 is the structural representation of gas defence box.
Accompanying drawing 2 is the filter cartridge structural representation of gas defence box.
Accompanying drawing 3 is the half mask structural representation of gas defence box.
Mark in the accompanying drawing is represented respectively: filter cartridge 1, half mask 2, gas-permeable nets 3, coarse filtration core 4, buckle cover 5, sealing plate 6, Button Block 7, cross filter core 8, air-breathing seat 9, air-breathing Button Block 10, exhaling hole 11, baffle plate 12, inlet valve 13, outlet valve 14, oronasal mask 15, bracelet 16, locating convex block 17, detent 18.
5, the specific embodiment
Below in conjunction with accompanying drawing gas defence box of the present utility model is done following detailed description the in detail.
As shown in Figure 1, gas defence box of the present utility model is characterized in that being made up of filter cartridge 1, half mask 2 and headband.
Outlet valve 14 is round and elastic films that the center is provided with installation shaft, and its installation shaft outer end is bigger, inserts the center mounting hole of exhaling hole 11 in exhaling hole 11 outsides.
Gas defence box of the present utility model is reasonable in design, simple in structure, safe and reliable, easy to use, thereby, have good value for applications.
