5. at the filter course place in air outlet valve thin slice outside, be provided with through hole, the gas of discharge need not pass through filter course, only through through hole and ventilative extexine, directly get rid of outside mouth mask, and air resistance is little, and exhaust is unimpeded, strengthens exhaust effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the cutaway view of Fig. 1.
The specific embodiment
In order to understand better the present invention, below in conjunction with accompanying drawing, explain in detail embodiments of the present invention.
As shown in Figure 1, a kind of dustproof filter-type respirator, comprise the cover body being connected, fixed band 4, described cover body comprises the ventilative extexine 1 connecting successively from outside to inside, filter course 3, endosexine 2, described endosexine 2 comprises the marginal portion 27 being connected, mid portion, the neighboring of marginal portion 27 is connected with extexine 1, mid portion comprises upper flat plate body 21, described upper flat plate body 21 is corresponding with naris position, the top of described upper flat plate body 21 is provided with nostril breather check valve, bottom is provided with nostril outgassing nonreturn valve, described nostril breather check valve comprises is located at upper flat plate body 21 near Yi Ce nostril, nostril intake valve groove, on the intake valve groove of nostril, be provided with air inlet rectangular opening 216, on air inlet rectangular opening 216, be coated with nostril intake valve thin slice 214, air inlet rectangular opening 216 is greater than the length of vertical direction along the lateral length of the nose left and right sides, nostril intake valve thin slice 214 is connected with the nostril intake valve groove on air inlet rectangular opening 216 left sides or right side, the area of nostril intake valve thin slice 214 is greater than the area of air inlet rectangular opening, nostril intake valve thin slice 214 covers air inlet rectangular opening completely.
The nostril intake valve groove on described air inlet rectangular opening 216 right sides is provided with nostril intake valve groove connecting hole 215, nostril intake valve thin slice 214 is provided with nostril intake valve thin slice connecting hole, and nostril intake valve thin slice 214 is connected with nostril intake valve groove plane by nostril intake valve groove connecting hole 215, nostril intake valve thin slice connecting hole and self-tapping screw.When nostril is air-breathing, pressure in space between endosexine 2 and face is less than the pressure in filter course 3, under the effect of inside and outside differential pressure, outside gas is inwardly pushed nostril intake valve thin slice 214 open predetermined gap, make outside air enter into the space between face, then by the suction body of nostril.
Described nostril outgassing nonreturn valve nose comprises the air outlet valve groove of being located near on the upper flat plate body 21 of filter course one side, on air outlet valve groove, be provided with the rectangular opening 213 of giving vent to anger, the described rectangular opening 213 of giving vent to anger is greater than the length of vertical direction along the lateral length of the nose left and right sides, on the rectangular opening 213 of giving vent to anger, be coated with air outlet valve thin slice 212, air outlet valve thin slice 212 is connected with the air outlet valve groove on give vent to anger rectangular opening 213 left sides or right side, the area of thin slice is greater than the area of rectangular opening, and air outlet valve thin slice 212 rectangular opening of giving vent to anger covers completely.While exhaling by nostril, pressure in space between endosexine 2 and face is greater than the pressure of 3 li of filter courses, under the effect of inside and outside differential pressure, the gas in internal voids is outwards pushed air outlet valve thin slice 212 open predetermined gap, makes inner Bas Discharged outside to filter course.Filter course 3 places in air outlet valve thin slice 212 outsides are provided with through hole 31, and the gas of discharge need not pass through filter course 3, only through through hole and ventilative extexine 1, directly get rid of outside mouth mask, and air resistance is little, and exhaust is unimpeded, strengthens exhaust effect.
