Abstract
The utility model relates to a self-inhalation filter dust-proof anti-toxin appliance, in particular to a ultra thin dust-proof anti-toxin breathing mask for daily wearing, which comprises an external decorative cloth layer, a fixing net, a filtering layer, a supporting net and a flexible bottom board with special shape. The outer side of the bottom board is provided with a supporting guiding bar and a supporting column for installing the supporting net which is laid with the filtering layer at the outer side and fixed by the fixing net. A mouth breathing hole is cut around the mouth part and provided on the inner side with breathing net which forms a breathing chamber with the supporting net. The mask of the structure has great improvement in air flowability of the breathing chamber and visual field performance in comparison with prior art. When the utility model is worn, the flexible bottom board enables the whole mask to adhere to face tightly with good seal effect, and the shape of the mask is similar to that of ordinary gauze mask and suitable for daily wearing of various facial forms.
Description
Technical field
The utility model relates to self-absorbing filtering type dust proof and gas defence apparatus, particularly a kind of suitable daily ultrathin antidusting and anti-poisoning mask of wearing.
Background technology:
Present common cotton cloth respirator and in be provided with the dust proof and gas defence interlayer cotton cloth respirator just hide and filter, protection effect and poor air-tightness because mouth mask is most of and face is pressed close to, make the respiratory air flow flowability poor, filter area is little.Fixture type, stent-type antidusting and anti-poisoning mask profile are big, and aesthetic property is poor, because of airtight scope is big, make air-tightness be difficult for guaranteeing, and dead space are bigger, and the visual field is little, is not suitable for daily wearing.
Summary of the invention:
Goal of the invention of the present utility model provides that a kind of protection effect is good, good looking appearance, be fit to the daily ultrathin antidusting and anti-poisoning mask of wearing.
The technical scheme that realizes the foregoing invention purpose is: this ultrathin type antidusting and anti-poisoning mask comprises the outer bunting bed of material, fixed network, filter course, supporting network and has abnormally-structured flexible plate, this plate outer side is provided with and supports fuisw rib and support column, by this support column supporting network is installed, this supporting network outside is laid filter course and is fixed by fixed network, have the mouth breathing hole in collar extension portion, the breathing net is equipped with in the inboard, hole, breathes between net and the supporting network to constitute respiratory cavity.When air-breathing, fresh air enters respiratory cavity through filtering layer; During expiration, the gas of exhalation is got rid of through filtering layer by respiratory cavity.Be that oral area is air-breathing and exhale all by this respiratory cavity.
Ultrathin antidusting and anti-poisoning mask according to technique scheme enforcement, the respiratory cavity that forms by abnormally-structured flexible plate, make the structure of mouth mask compact more, reasonable, support fuisw rib and can strengthen gas flow, overcome under the prerequisite of respiratory resistance in assurance, making dead space is that respiratory cavity is reduced to minimum, improves a lot than prior art in the visual field.When adopting collar extension nose all-sealed structure, can make mouth mask thickness reach the thinnest, the similar common cotton cloth respirator of profile adapts to that various shapes of face are daily to be worn.
Description of drawings:
Fig. 1 is a horizontal section schematic diagram of the present utility model (cutting open through the respiratory cavity central cross).
Fig. 2 is the utility model longitudinal profile schematic diagram of no nasal respiration head (through the respiratory cavity central longitudinal to cutting open).
Fig. 3 is the utility model longitudinal profile schematic diagram that the nasal respiration head is arranged (through the respiratory cavity central longitudinal to cutting open).
The specific embodiment:
Provide specific embodiment of the utility model below in conjunction with accompanying drawing.
Fig. 1, Fig. 2 have provided the of the present utility model general structure embodiment of no nasal respiration head, it is made up of flexible plate 1, sealing strip 2, support fuisw rib 3, support column 4, breathing net 5, respiratory cavity 6, supporting network 7, filter course 8, fixed network 9, the outer bunting bed of material 10, having abnormally-structured flexible plate 1 its arranged outside has and its all-in-one-piece support fuisw rib 3 and support column 4, and this supports fuisw rib 3 and support column 4 forms latticed supporting construction.By this support column 4 supporting network 7 is installed, filter course 8 and fixing by fixed network 9 is laid in these supporting network 7 outsides, has the mouth breathing hole in collar extension portion, and the inboard, hole is equipped with and is breathed net 5, breathes to constitute respiratory cavity 6 between net 5 and the supporting network 7.This structure adopts the hermetically sealed form of collar extension nose, and promptly the sealing strip 2 of collar extension nose is equipped with in flexible plate 1 inboard.Therefore, its profile is similar to common cotton cloth respirator, and only its thickness is slightly thicker than common cotton cloth respirator.
Fig. 2 has also provided the specific embodiment of the utility model that the nasal respiration head is arranged in conjunction with Fig. 1.It by flexible plate 1, sealing strip 2, support fuisw rib 3, support column 4, breathe net 5, respiratory cavity 6, supporting network 7, filter course 8, fixed network 9, the outer bunting bed of material 10, nasal respiration 11 form.The difference of the mouth mask of this structure and aforementioned structure is: the nasal respiration that flexibly connects with it 11 is equipped with on the top of respiratory cavity 6, and this nasal respiration 11 is short tube shape structure, and its outside has rib 12, rib 12 shooting property of overcoat crusts 13.This structure adopts the seal form of collar extension portion, and promptly the sealing strip 2 of collar extension portion is equipped with in flexible plate 1 inboard.When wearing this structure mouth mask, nostrils are inserted in nasal respiration 11, and the space back-pressure of air between rib 12 when air-breathing is close to around the nostril so that airtight around the nasal respiration 11 the elasticity crust 13 of nasal respiration 11.Nasal respiration 11 flexibly connects with respiratory cavity 6 tops, makes nasal respiration 11 that certain amplitude of oscillation be arranged, and it is comfortable to guarantee that the user wears.
