Removable airtight air cushion mouth mask
Technical field
The utility model is applied to the safe and sanitary field, refers to especially that a kind of obturation effect is good, conveniently uses, saves use cost and has the removable airtight air cushion mouth mask of environmental protection concurrently.
Background technology
General epidemic virus is a lot, and is especially serious with the saliva infection, for example: flu, SARS (SARS) ... etc., therefore for the protection of mouth, nose, widely common people note, but general mouth mask protection effect may not be certain effective.
Therefore have the mouth mask of so-called cup formula on the market, for example checked and approved Taiwan patent announcement number several the 25317 No. two " can adjust the mouth mask of elasticity ", it mostly was the filter body end face and was provided with an iron plate, utilize the flexible of iron plate, to fit in bridge of the nose position, and make the mouth mask cover close mouth and nose position in the user, but the degree of flexibility of iron plate is limited, still can't be effectively change effectively this mouth mask driving fit in user's face according to user's shape of face, and be easy to generate trickle gap, cause the leak of protection; Moreover generally mouth mask is because the filter effect of contained activated carbon mostly can only be kept three to six hours, and therefore good protection needs per three hours, changes one time mouth mask, and causes the problem that use cost significantly increases and environmental protection is not good.
Summary of the invention
The utility model, still has the shortcoming that protection effect is not good, cost is high and environmental protection is not good to exist, and is redesigned on reality is used in view of aforementioned existing cup formula mouth mask.
Main purpose of the present utility model is for providing a kind of removable airtight air cushion mouth mask, it utilizes the complete driving fit of soft air cushion energy in user face, prevent side leakage and reach permanent protective property, and have conveniently replaced filter body simultaneously that it is good to reach reduction user cost and environment protecting.
In order to reach aforesaid utility model purpose, the technological means that the utility model used is to provide a kind of removable airtight air cushion mouth mask, it comprises an air cushion, this air cushion is established the soft ringwise and inner pneumatophore that is filled with air, and this air cushion one face closure is fixed with a cover body, this cover body is provided with a ventilating part, run through in this ventilating part and be provided with a passage, and in the both sides of this cover body the outstanding respectively ear that is provided with, and this ventilating part periphery is provided with a tearable filter body that changes, and the periphery of this filter body fits tightly the outer peripheral edges in this ventilating part.
The utility model utilizes above-mentioned technological means and after implementing, because this air cushion is constituted by soft air bag, therefore this air bag utilizes the gas indefiniteness, for the shape of face of this air bag physical efficiency according to the user, fully driving fit be covered with shut up, nose, significantly promote airtight effect, reduce the leak of protection, and cooperate this filter body energy conveniently replaced, and can reuse for the cover body and the air cushion of this mouth mask in this cover body, reduce cost waste, and with the effect of environmental protection.

The specific embodiment
As shown in Figures 1 to 4, removable airtight air cushion mouth mask of the present utility model, it comprises an air cushion 10, and this air cushion 10 is established the pneumatophore of filling air in the soft ringwise colloid, and this air cushion 10 is made as nearly rhombus, and is concaved with a recess 11 for bridge of the nose closing in the top;
One cover body 20, this cover body 20 is floating prominent shape sealing and is fixed in the one side that this air cushion 10 differs from this recess 11, and the face shaping of these cover body 20 relative these air cushions 10 is established and is nearly rhombus, this cover body 20 even extends the ventilating part 21 that both sides are concaved with a shallow slot shape in central authorities, run through in this ventilating part 21 and be laid with a plurality of passages 22, and all sides that this ventilating part 21 differs from this passage 22 are respectively equipped with a plurality of combination bore that run through 23, each combination bore 23 uniformly-spaced is provided with a plurality of lobes 230 towards central projection respectively outwardly, and the top side that this cover body 20 differs from this ventilating part 21 is respectively equipped with two non-return valves 24, and two non-return valves 24 run through three steam vents 25 of this cover body 20 and circular array and a cover respectively and close valve block 26 in this steam vent 25, and in the both sides of this cover body 20 the outstanding respectively ear 27 that wears for rope body 28 that is provided with;
One filter body 30, this filter body 30 is located at this ventilating part 21, and is same as the circumferential profile setting of this ventilating part 21, and that this filter body 30 is provided with towards these cover body 20 directions is a plurality of in conjunction with protuberance 31, be embedded in each combination bore 23 for each in conjunction with protuberance 31, and periphery is subjected to lobe 230 clampings of closing; By above-mentioned structure, to finish removable airtight air cushion mouth mask of the present utility model.
When using, as shown in Figures 2 and 3, two ears 27 of this cover body 20 can link respectively be provided with the rope body 28, so that the user is hung on ear, and utilize the complete driving fit of these air cushion 10 energy in user's mouth and nose periphery, effectively promote the effect of protection, and the user is after air being filtered by this filter body 30, air-breathing for the user through each passage 22 when breathing, and when feeling elated and exultant, can utilize this non-return valve 24 that waste gas is spued, in use for some time simultaneously, i.e. this 30 filtrable times of filter body, just can conveniently and easily this filter body 30 be pulled away this cover body 20, re-use new filter body 30 and be incorporated into this ventilating part 21, more can continue to filter clean air, after being used, can sterilize this air cushion 10 and cover body 20 are to reach the repeated use effect of safety and sanitation.
