Abstract

The utility model belongs to a dust-proof anti-toxin mouth and nose mask, composed of a mask body, an air suction hole, an air expiratory valve, a filtering box, a sweat discharging hole and a fixing strap. The air suction hole is positioned on both sides of the middle of the mask body, and the filtering box is inlaid into the air suction hole; the air expiratory valve is fixed on the middle lower part of the middle of the mask body, and the sweat discharging hole is fixed on the lower part of the middle of the mask body; the fixing strap is buckled on the middle upper part of both side edges of the mask body. The dust-proof anti-toxin mouth and nose mask has the advantages of little dead space, favorable dust-proof and anti-toxin effect, cool, convenient and comfortable feeling, convenient assembly and disassembly, and easy replacement.

Description

The dust proof and gas defence oronasal mask
The utility model belongs to the respiratory protection equipment technical field.
At present, it is dustproof that people use, and gas mask is generally bigger, when hot summer is used, hidden most of face, make the people feel sultry discomfort, because the scope of being covered is bigger, dead space is also bigger, and the fresh air of suction is less, and in the big place of labour intensity, it is unhappy that the user feels.
The purpose of this utility model is exactly in order to overcome above-mentioned shortcoming, provides a kind of filtration gas defence effective, features simple structure, and the dead space scope is little, uses comfortable dust proof and gas defence oronasal mask.
The technical solution of the utility model is finished like this: this dust proof and gas defence oronasal mask, it is characterized in that by cover body, suction hole, outlet valve, filter cartridge, sweat discharging hole and fixed band are formed, suction hole is positioned at both sides, cover body middle part, and filter cartridge embeds in the suction hole, and outlet valve is fixed on below in the middle part of cover body, sweat discharging hole is fixed on below, cover body middle part, and fixed band is buckled in position, top position in the cover body dual-side.
As further improvement of the utility model, the dust proof and gas defence oronasal mask is detachably separated between its mouth cover and nose cup, can unload the mouth cover, uses nose cup separately.
As another kind of improvement the of the present utility model, the suction hole of dust proof and gas defence oronasal mask and outlet valve position can exchange mutually, filter cartridge also changes with the position of suction hole, outlet valve is fixed on the medium position of cover body, because after the position changes, filter cartridge also has two original changes to be installed as one, can increase the visual angle when using like this, and it is also more suitable to use.
The utlity model has following advantage: features simple structure, light and handy, volume is little, dead space is few, and is more nice and cool than common dust proof and gas defence face shield, light during use because few with the face contact area, feels comfortable; Filter malicious box and use new material-activated carbon fiber cloth, can alleviate the weight of gas mask greatly, reduce labor strength, because it is dead space is few, fresher than common dust proof and gas defence face shield suction air; According to its usefulness of the required selection in field of employment, and convenient disassembly, change easily.
Fig. 1 is the utility model side-looking examination structural representation.
Fig. 2 is the utility model A type side-looking structural representation.
Fig. 3 is the utility model Type B side-looking structural representation.
Now further describe embodiment in conjunction with Fig. 1: this dust proof and gas defence oronasal mask side view is a left-right symmetry, it is by cover body 1, filter cartridge 2 in the suction hole, outlet valve, sweat discharging hole 5 and two fixed bands 6,7 form, suction hole is positioned at cover body 1 middle part two side positions, filter cartridge 2 is by filtering the dirt box or filtering malicious box (jar) and form, and in the embedding suction hole, outlet valve is made up of with expiration sheet 4 seat 3 of exhaling, expiration sheet 4 is made by soft rubber, expiration sheet 4 places in the interior circle of seat 3 front ends of exhaling, and fixedly connected with the other end of circle core shaft, the centre bore of the other end insertion expiration valve seat 3 of circle core shaft is fixedly connected, whole outlet valve embeds in the exhaling hole of below in cover body 1 middle part, the below of cover body 1 also has a sweat discharging hole 6, sweat discharging hole 6 is the hollow cone shape, in establish a ball float, there is a cross spacing ring 5 the hollow cone top, the corresponding little lug in the dual-side of spacing ring 5 and cover body 1 below is gluing fixing, certain interval is arranged, between spacing ring 5 and ball float after sweat flows to steam vent, because the proportion of ball float is lighter than sweat, ball float come-up, sweat flow out cover body 1 under the gravity effect, also be fixed with two fixed bands 7 with lower position above in the cover body dual-side, one little button frame is arranged on 8 fixed bands 7,8, and fixedly connected after plastic rivet on the cover body 1 dual-side opposite position interlocks.
Fig. 2 is the utility model A type side-looking structural representation, and left-right symmetry, it is a kind of innovative product of the present utility model, its difference is between smallmouth cover 9 and nose cup detachable, have one to connect and softly to be with 8 on the smallmouth cover 9, soft with 8 an end and smallmouth cover 9 gluing fixedlying connected, the other end is loaded onto little triangle button frame, be buckled on the plastic rivet corresponding to cover body 1, smallmouth cover 9 has just fused with cover body 1 like this, sometimes, as get when expecting that discharging need not with the mouth cover, only need press little triangle button frame just can unload the mouth cover, another difference of Fig. 2 and Fig. 1 is that also the outlet valve 3 and the position of suction hole can exchange mutually, outlet valve 3 is fixed on cover body 1 medium position, suction hole and 4 the middle lower positions of filter cartridge that embed on the suction hole at the cover body middle part, when the utility model employing filter dirt box or with activated carbon fiber cloth 6, when superfine fibre filter paper 5 is the filter poison box of filtering material, because the weight of two box bodys is lighter, can directly embed in the suction hole of cover body 1 as Fig. 1 mode, if but when adopting active carbon particle to make filtering material, because weight is heavier relatively, for fixed, design one base 2 on cover body 1, and fix on the cover body 1 by being adhesively fixed, one screw socket is arranged on the base 2, and canister 4 is fixedlyed connected with the screw socket on the base 2 by nut, after the outlet valve of Fig. 2 and the position of suction hole change, filter cartridge is changed into by original two and is installed one, the visual angle is increased, and it is more suitable to use, and 7 among the figure is sweat discharging hole, 10,11 is that fixed band is all identical with Fig. 1 structure.
Fig. 3 is the utility model Type B side-looking structural representation, is similarly left-right symmetry, and it is a kind of simple type product of the present utility model, and the difference of it and Fig. 1 is that mouth cover and nose cup fuse and is that non-dismountable formula, whole cover body cover face's lower lip and end.
