Description

The gas defence box
1, technical field
The utility model relates to a kind of labour protection protective articles, specifically a kind of gas defence box that is used for the air pollution environment.
2, background technology
In various industrial production environments, have some operation places usually and contain various toxic gases, as benzene, chlorine, acetone, carbon disulfide, carbon tetrachloride, chloroform, Celfume, chloromethanes, nitroparaffin, alcohols, phenyl amines etc.The concentration of various toxic gases exceeds the health standard, and long-term unshielded measure ground is under this contaminated environment, can directly influence life and health.
For preventing various dust and being with malicious air to suck, in the contaminated environment of air, wear breathing mask usually.Existing dust proof and gas defence mask causes when the contaminated environment operation because of volume is too big, influences operating efficiency.The unreasonable structure that has, it is poor to seal, and leaks greatly, and easily aging yielding, profile is not attractive in appearance, the not high shortcoming of cost performance.
3, summary of the invention
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.
Filter cartridge 1 is fixed on the air-breathing Button Block 10 of half mask 2 by air-breathing seat 9.The silk ribbon string of headband is in the bracelet 16 of half mask.
Filter cartridge 1 is a rounded cylindrical, and front end is provided with gas-permeable nets 3, gas-permeable nets 3 arranged outside coarse filtration cores 4, its outer end is fixing by button cover 5, the sealing plate 6 of rear end is provided with air-breathing seat 9, and the bilateral symmetry of air-breathing seat 9 is provided with locating convex block 17, is provided with filter core 8 between gas-permeable nets 3 and the sealing plate 6.
Half mask 2 front end arranged outside have circular air-breathing Button Block 10, and the arranged outside of air-breathing Button Block 10 has and the corresponding flange of air-breathing seat 9 inboard grooves.Bilateral symmetry at air-breathing Button Block 10 is provided with and locating convex block 17 corresponding detents 18, and air-breathing Button Block 10 belows are provided with exhaling hole 11, is provided with baffle plate 12 between the air-breathing Button Block 10 in half mask 2 outsides and exhaling hole 11.Baffle plate 12 half is wrapped in the first half of exhaling hole 11, stops that effectively the liquid that condenses on the inlet valve 13 flows on the outlet valve 14, causes outlet valve 14 sealings to reduce and expiratory dyspnea.In the air-breathing Button Block 10 inlet valve 13 is set, outlet valve 14 is set in the exhaling hole 11.Half mask 2 arranged outside have the oronasal mask 15 that meets face's shape, and both sides are provided with bracelet 16.
