Specific embodiment
As shown in attached drawing 1 to attached drawing 6:
The present invention provides a kind of fire protection mask, including main body 1, watch window 2, filtering tank 3, neck cover 4, gas vent 5, pressure
The front end insertion of slot 6 and liquid valve 7, main body 1 is provided with watch window 2, and 1 front end of main body is provided with filtering tank 3 close to bottom end insertion,
The bottom end insertion of main body 1 is provided with neck set 4, and the both-side opening of main body 1 is provided with gas vent 5, and the inner tip insertion of main body 1 is set
It is equipped with head tank 6, insertion is provided with liquid valve 7 close to top for the inside of main body 1；
Head tank 6 includes pressure plare 601, air bag 602 and air valve 603, and pressure plare 601 is embedded in the top for being set to head tank 6, gas
Capsule 602 is embedded in the inside for being set to head tank 6, and air bag 602 is located at the lower section of pressure plare 601, and the opening of air valve 603 is set to pressure
The top of power slot 6；
Liquid valve 7 includes liquid bath wall 701, link slot 7011, retraction slot 7012, tongue 702, fixed valve 703, link block 7031, bullet
Property valve 7032 and elastic base 704, the insertion of liquid bath wall 701 is set to around liquid valve 7, and the opening of link slot 7011 is set to liquid bath
For the inner wall of wall 701 at one end, retraction slot 7012 is fixedly connected on the side of link slot 7011, and tongue 702 is fixedly connected on
One end of liquid bath wall 701, fixed valve 703 are embedded in the middle part for being set to liquid bath wall 701, and link block 7031 is fixedly connected on fixed valve
Around 703, feather valve 7032 is fixedly connected on the middle part of fixed valve 703, and the insertion of elastic base 704 is set to liquid bath wall 701
Bottom end.
Wherein, the bottom end surface protrusion of pressure plare 601 is provided with several conic convex, and is lived by the sliding rail of surrounding
Dynamic connection is moved down when by hitting by pressure plare 601 and air bag presses, so that air bag is broken.
Wherein, the opening diameter of air valve 603 and the diameter of 701 top end opening of liquid bath wall mutually agree with together, pass through air valve
Air bag can be that the air-flow generated enters in liquid valve 7 breaking by 603.
Wherein, link slot 7011 is the opening of inclined triangular shape setting, and the table of liquid bath wall 701 is arranged in bottom end protrusion
Face can allow fixed valve 703 to be connected to the middle part of liquid bath wall 701 by link slot 7011.
Wherein, the crooked radian of retraction slot 7012 is bigger than the open loop radian of link slot 7011, passes through retraction slot
7012 can receive the feather valve 7032 at 703 middle part of fixed valve toward center when being pressed down by air pressure in fixed valve 703
Contracting is together.
Wherein, it is the triangle setting with crooked radian, and the volume of front end portion that tongue 702, which is liquid bath wall 701,
Mutually agree with link slot 7011, can pass through protrusion when liquid flows out by the protrusion of tongue 702 can be by water flow
It flows up, can spread out when then falling.
Wherein, the setting in rounded shape of feather valve 7032, and diameter is consistent by the diameter of proximal portion with liquid bath wall 701, leads to
Crossing can be to central reduction, so that liquid bath wall 701 is opened when feather valve 7032 allows fixed valve 703 to move down.
Wherein, liquid bath wall 701 be several mutually around permutation and combination moreover, and liquid bath wall 701 it is mutually arranged at spherical shape
Shape setting, by fluid storage at middle part when collapsing by the bending of liquid bath wall 701, then in fixed valve 703 toward moving down
Can not each liquid bath wall 701 be fixed and be connected when dynamic, allow liquid outflow to cooling down on head.
Wherein, 704 semicircular in shape shape of elastic base be arranged, and middle part be hollow form be arranged, by elastic base 704 by
To two side stretchings when pressure, so that the gap between its liquid bath wall 701 becomes larger, so that liquid bath wall 701 is easier to be opened.
Working principle:
First then main body 1 is observed surrounding from 4 wearing headed of neck set by watch window 2, then passed through
Filtering tank 3 is breathed to filter the air, then the air of exhalation is discharged by gas vent 5, then when there is peculiar smell to fall
The pressure plare 601 that falling when lower can touch when 1 top of main body on head tank 6 it is carried out pressure testing allow its down
It is mobile, air bag 602 can be squeezed when moving down, so that air bag 602 is broken, internal air be allowed to spray, and
Air can be entered in liquid valve 7 by air valve 603, be pressed to fixed valve 703, allow fixed valve 703 to move down, in movement
When link block 7031 can fall off away from link slot 7011, then because the tilt angle of retraction slot 7012 is smaller can allow it is solid
Valve 703 is determined when mobile to central reduction, liquid bath wall 701 can disperse around after fixed valve 703 detaches,
It allows internal liquid to flow out, can finally be applied to elastic base 704 when fixed valve 703 moves down and squeezes liquid
Power so that elastic base 704 can be extended to two sides liquid bath wall 701 can more easily be opened.
