Abstract
The utility model relates to a self-respiration filtration type dustproof and antigas appliance, particularly a dustproof and antigas mask which is suitable for daily wear. A main body of the dustproof and antigas mask is a flexible bottom board which has a special-shaped structure. The bottom board and a supporting net on the outer side of the bottom board form a gas inlet room of both cheeks and a gas outlet room of a mouth, and the bottom board and a respiratory net on the inner side of the bottom board form a respiratory cavity. An inspiratory valve and an expiratory valve are arranged between the gas inlet room and the respiratory cavity and between the gas outlet room and the respiratory cavity. A supporting diversion rib is arranged between the flexible bottom board and the supporting net. The performance of a dead cavity, visual field, etc., of the dustproof and antigas mask with the structure is largely enhanced than the prior art. When the dustproof and antigas mask is worn, the flexible bottom board makes the whole dustproof and antigas mask tightly attached to a face. The utility model has good sealing effect. The appearance of the dustproof and antigas mask is similar to an ordinary gauze mask. The dustproof and antigas mask is suitable for daily wear.
Description
Technical field
The utility model relates to self-absorbing filtering type dust proof and gas defence apparatus, particularly a kind of suitable daily antidusting and anti-poisoning mask of wearing.
Background technology:
Have at present dustproof or dust proof and gas defence with have common cotton cloth respirator, in be provided with cotton cloth respirator, fixture type antidusting and anti-poisoning mask, stent-type antidusting and anti-poisoning mask and the compound antidusting and anti-poisoning mask of dust proof and gas defence interlayer, 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 respiratory air flow mobile poor, filter area is little.Fixture type, stent-type and compound 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 antidusting and anti-poisoning mask of wearing.
The technical scheme that realizes the foregoing invention purpose is: this antidusting and anti-poisoning mask comprises filter course, supporting network, inlet valve, outlet valve and has abnormally-structured flexible plate, this base plate constitutes the inlet plenum of two cheeks and the discharge chamber of oral area with the supporting network that is contained in its outside, constitute respiratory cavity with the breathing net that is contained in its inboard, inlet valve and outlet valve are housed respectively between this inlet plenum and discharge chamber and the respiratory cavity, are provided with the support fuisw rib between flexible plate and the supporting network.When air-breathing, outlet valve ends, and inlet valve is opened, and air enters inlet plenum through outside filter course, enters respiratory cavity through inlet valve again.During expiration, inlet valve ends, and outlet valve is opened, and the gas of exhalation enters discharge chamber and gets rid of from outlet valve.
According to the antidusting and anti-poisoning mask that technique scheme is implemented, its abnormally-structured flexible plate promptly forms turnover, air chamber and forms respiratory cavity again, makes its structure compact more, reasonable, improves a lot than prior art in the dead space and the visual field of mouth mask; Have the support fuisw rib in the inlet plenum, can strengthen gas flow; When adopting collar extension nose all-sealed structure, can make mouth mask thickness reach the thinnest, minimum thickness is about 5mm, and the similar common cotton cloth respirator of profile, so good looking appearance are suitable for daily wearing.When wearing, flexible plate makes whole mouth mask be close to face, and good sealing effect adapts to various shapes of face.
Description of drawings:
Fig. 1 is a horizontal section schematic diagram of the present utility model (cutting open along the inlet valve central cross).
Fig. 2 is the utility model longitudinal profile schematic diagram of no nasal respiration head (along the inlet valve central longitudinal to cutting open).
Fig. 3 is the utility model longitudinal profile schematic diagram that the nasal respiration head is arranged (along the inlet valve 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 has provided the of the present utility model general structure embodiment of no nasal respiration head, it is by flexible plate 1, sealing strip 2, inlet valve 3, breathe net 4, outlet valve 5, discharge chamber 6, respiratory cavity 7, inlet plenum 8, the outer bunting bed of material 9, fixed network 10, filter course 11, supporting network 12, supporting fuisw rib 13 forms, have abnormally-structured flexible plate 1 and constitute the inlet plenum 8 of two cheeks and the discharge chamber 6 of oral area with the supporting network 12 that is contained in its outside, constitute respiratory cavity 7 with the breathing net 4 that is contained in its inboard, inlet valve 3 and outlet valve 5 are housed respectively between this inlet plenum 8 and discharge chamber 6 and the respiratory cavity 7, be provided with between flexible plate 1 and the supporting network 12 and support fuisw rib 13, help air when air-breathing and flow.The antidusting and anti-poisoning mask of 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.Its filtration fraction structure of the antidusting and anti-poisoning mask of this structure is: filter course 11 is equipped with in the outside of supporting network 12, and fixed network 10 is equipped with in these filter course 11 outsides, and these fixed network 10 outsides are covered with the outer bunting bed of material 9.Therefore, its profile of the antidusting and anti-poisoning mask of this structure 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, inlet valve 3, breathe net 4, outlet valve 5, discharge chamber 6, respiratory cavity 7, inlet plenum 8, the outer bunting bed of material 9, fixed network 10, filter course 11, supporting network 12, support fuisw rib 13, nasal respiration 14 forms.The difference of the antidusting and anti-poisoning mask of this structure and the mouth mask of aforementioned structure is: the nasal respiration that flexibly connects with it 14 is equipped with on the top of respiratory cavity 7, and this nasal respiration 14 is short tube shape structure, and its outside has rib 14, rib 15 shooting property of overcoat crusts 16.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 14, and the space back-pressure of air between rib 15 when air-breathing is close to around the nostril so that airtight around the nasal respiration 14 a nasal respiration elasticity crust 16.Nasal respiration 14 flexibly connects with respiratory cavity 7 tops, makes nasal respiration 14 that certain amplitude of oscillation be arranged, and it is comfortable to guarantee that the user wears.
