Abstract
A mask seal protective cover overcomes defects of conventional masks such as poor air tightness, high cost, or difficult recycle and the like. The protective cover is a light appliance for providing seal protection or security for various masks or mask filter fabrics and mainly consists of a ring-like frame, securing straps at both sides of the frame, and an inflatable airbag attached to the frame, wherein the inflatable airbag is between the frame and the mask when in use for compressing the periphery of the mask, so that the periphery presses close to a user's face. The straps at the both sides of the frame for securing the mask seal protective cover to the face can be provided with a flexible securing device so as to adjust an effective length of the securing straps. The utility model includes the mask seal protective cover and a scheme for use in combination with breathable fabrics which can filter gas pollutants. The mask seal protective cover can improve the air tightness of the mask and is light in weight and recyclable, thereby reducing waste of mask materials.
Description
Affiliated technical field
The utility model relates to a kind of sealed protective cover for mask.
Background technology
At present, common mouth mask is not strong in the air-tightness around it, causes its protective capacities not strong.Though and but other senior mouth masks have the metal bead of deformation at bridge of the nose place, realize good docile and obediently but still be difficult to full shape of face to the user, and senior mouth mask costs an arm and a leg, and is difficult for promoting, and is difficult to repeatedly use.
Summary of the invention
Strong or involve great expense in order to overcome above-mentioned mouth mask air-tightness, shortcoming such as be difficult to repeatedly use, the utility model provides a kind of sealed protective cover for mask, and this utility model is to provide sealing protection or fixing light utensil for various mouth masks or mouth mask filter lining.
The technical scheme that the utility model adopted is: sealed protective cover for mask is mainly by the frame of sub-circular, the belt that the frame both sides are used for fixing, and the inflatable bladders that invests on this frame forms, this air bag presents the flexible pipe of a sub-circular after inflation.This air bag flexible pipe between frame and mouth mask, and is realized around it and user face well docile and obedient compressing around the mouth mask to make when using the utility model.But some part of hard material such as duroplasts that can some parts adopts frame adopts the metal bead of deformation etc. to have the material of better deformability to make, thereby make frame not only can keep good solid form in use but also can regulate shape by the user, and be convenient to fold at positions such as the bridge of the noses.This air bag flexible pipe can be made by light gas impermeable materials such as polychloroethylene films, and has that gas port to be opened/closed is used to fill, exhaust.Above-mentioned air bag also can make liquid capsule or other physical propertys flexible material suitable with it into.Being used for fixing sealed protective cover for mask in use and can having as Telescopic Fixed devices such as Small clamps in the belt of face of frame both sides is so that the effective length of regulating the belt that is used for fixing when using.In addition, also can around frame, increase as fixtures such as clips, thereby have the ventilative lining of filtering gas pollutant function using only to adopt, and make it be fixed in the said fixing device, and be pressed by air bag and realize the isolation of user's mouth and nose and outside contamination.Above-mentioned lining cutting in use also can cut in advance and place these linings of some parts sealing bag to preserve, and the utility model has comprised the scheme that this sealed protective cover for mask and above-mentioned lining are used in combination.
The beneficial effects of the utility model are that can be embodied as various mouth masks or mouth mask filtration lining provides sealing protection or fixing, thereby improves the mouth mask air-tightness, and waste light, that can repeatedly use, reduce mask material repeatedly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a front perspective view of the present utility model.
1. frames among the figure, 2. air bag, the belt that 3. is used for fixing, gas port 4. to be opened/closed, the 5. Telescopic Fixed device of belt 6. is used for fixing the fixture of filtering gas pollutant lining, the ventilative lining that 7. has filtering gas pollutant function around the frame.
The specific embodiment
In the embodiment shown in fig. 1, sealed protective cover for mask is mainly by the frame (1) of sub-circular, the belt that the frame both sides are used for fixing (3), and the inflatable bladders (2) that invests on this frame forms, this air bag (2) presents the flexible pipe of a sub-circular after inflation.This air bag flexible pipe (2) between frame and mouth mask, and is realized around it and user face well docile and obedient compressing around the mouth mask to make when using the utility model.Frame (1) but can some parts adopt some part of hard material such as duroplasts to adopt the metal bead etc. of deformation to have the material of better deformability to make, thereby make frame (1) not only can keep good solid form in use but also can regulate shape by the user, and be convenient to fold at positions such as the bridge of the noses.This air bag flexible pipe (2) can be made by light gas impermeable materials such as polychloroethylene films, and has that gas port to be opened/closed (4) is used to fill, exhaust.The frame both sides be used in use fixedly that sealed protective cover for mask can have as Telescopic Fixed devices (5) such as Small clamps in the belt (3) of face so that the effective length of regulating the belt that is used for fixing when using.In addition, also can around frame, increase, replace mouth mask at the ventilative lining (7) that uses only employing to have filtering gas pollutant function, and make it be fixed in said fixing device (6) as fixtures such as clip (6).This lining (7) that sealed protective cover for mask can be covered in suitable area go up to use, and this lining is close to user face by air bag (2) institute pressure place and is realized the isolation of user's mouth and nose and outside contamination.This lining (7) can also can be cut in advance and be placed some parts of these linings (7) sealing bag to preserve by user's cutting prepares against use.The utility model has comprised the scheme that this sealed protective cover for mask and above-mentioned lining are used in combination.
