Description
Technical Field
The utility model relates to the technical field of articles for daily use, especially, relate to a foldable filter core gauze mask of replacing.
Background
The mask is a daily protective sanitary article, is widely used in hospitals and is also applied to a plurality of places with high pollution. Common gauze mask is the plane gauze mask of being made by gauze or non-woven fabrics, the unable better dust and the virus etc. of filtering in the air of simple cloth, because people's facial profile is respectively different, the gauze mask of single size is difficult to laminate different people's face, and simultaneously, most gauze masks are disposable gauze masks or need the whole cleaning of gauze mask after just can reuse, this will be unfavorable for same gauze mask of consumer's continuous use, often need prepare the replacement gauze mask, and the function of each gauze mask is more single usually, can't adapt to multiple occasion demand.
SUMMERY OF THE UTILITY MODEL
The utility model provides a foldable filter core gauze mask of replacing solves current gauze mask and can not continuous use, function singleness scheduling problem.
The utility model discloses the following technical scheme of accessible realizes:
the utility model provides a foldable filter core gauze mask of replacing, includes that the edge overlaps the design and has elastic skin and inlayer, forms the space that is used for holding the filter core between the two, outer middle part is provided with the fretwork, the middle part of inlayer corresponds the person's of wearing mouth nose position and is provided with the opening, and both ends respectively set up an ear-hang about it, be provided with vertical crease on skin and the inlayer, through vertical crease realizes that the bilateral symmetry of gauze mask is folding.
Further, outer, inlayer and two ear-hooks set up integrated into one piece formula structure, adopt the TPU material to make, leave the appointed distance between the edge of open-ended and the edge of inlayer for bear the weight of the filter core.
Furthermore, the outer layer adopts a three-dimensional arch structure, a V-shaped part which protrudes outwards is arranged at a position close to the nose bridge, and a nose bridge strip is embedded in the edge of the V-shaped part.
Further, a PH test paper interlayer is arranged inside the filter element and used for detecting weak acidity generated by reaction of breath of a wearer and water vapor.
Further, the filter element sequentially comprises a water absorption layer, a pH test paper interlayer, a silver ion filtering layer and a waterproof layer.
The utility model discloses profitable technological effect lies in:
through the design of edge overlap and have the space that forms between elastic skin and the inlayer, it uses it to hold the filter core, can conveniently carry out the change of filter core with the help of inlayer upper shed to improve the utilization ratio and the health level of gauze mask, utilize vertical crease on skin and the inlayer simultaneously, can realize that the gauze mask is folding, reduce its volume, be convenient for deposit, fretwork 11 design on outer 1 in addition can increase the air exchange, guarantee to breathe smoothly, the practicality of whole gauze mask is strong, convenient to popularize and apply.

fig. 2 is a schematic perspective view of the mask of the present invention;
wherein, 1-outer layer, 11-hollow, 12-V type part, 2-inner layer, 21-opening, 3-filter core, 4-ear-hang, 5 longitudinal crease and 6-nose bridge strip.
Detailed Description
The following detailed description of the preferred embodiments of the present invention is provided in connection with the accompanying drawings.
Referring to the attached drawing 1, the utility model provides a foldable replaceable filter element mask, including the edge overlapping design and have elastic skin 1 and inlayer 2, form the space that is used for holding filter core 3 between the two, be provided with fretwork 11 at the middle part of skin 1, correspond the oronasal position of the person of wearing at the middle part of inlayer 2 and be provided with opening 21, both ends respectively set up an ear-hang 4 about it, all are provided with vertical crease on skin 1 and inlayer 2, through this vertical crease 5, realize that the bilateral symmetry of mask is folding. Like this, with the help of opening 21, can put into filter core 3 or take out the space between outer 1 and the inlayer 2, convenient replacement to improve the utilization ratio and the health level of gauze mask, utilize vertical crease 5 simultaneously, can realize that the gauze mask is folding, reduce its volume, be convenient for deposit, fretwork 11 design on outer 1 in addition can increase the air exchange, guarantees to breathe smoothly.
In order to improve the fit degree of the mask and the face of a wearer, the outer layer 1, the inner layer 2 and the two ear hooks 4 are arranged into an integral structure and are made of TPU materials, the TPU is thermoplastic polyurethane, is a high polymer material between rubber and plastic and is divided into polyester type and polyether type, the hardness range is wide, the TPU can be 60A-85D, and the TPU is wear-resistant, oil-resistant, transparent and good in elasticity and can be widely applied to the fields of daily necessities, sports goods, toys, decorative materials and the like.
A given distance, which may be specific to the filter insert 3, is left between the edge of the opening 21 in the inner layer 2 and the edge of the inner layer 2 for carrying the filter insert 3. Meanwhile, part of the edge of the opening 21 can reach the edge of the inner layer 2, and the filter element 3 is supported by the remaining part and the outer layer 1 together, for example, a part of the opening 21 is respectively reserved in the upper, lower, left and right directions and can not reach the edge of the inner layer 2, so that the material can be saved, and the functional requirement of the inner layer 2 can be met. It is of course also possible to glue the filter insert 3 to the inner edge of the outer layer 1 or to the outer edge of the inner layer 2 by means of water-soluble glue or the like.
This skin 1 adopts three-dimensional arch-shaped structure, is provided with outside bellied V type portion 12 near the bridge of the nose position, and its edge is embedded to have nose bridge strip 6, and this nose bridge strip 6 can adopt resin material to make, and it has the bending deformation along with the exogenic action like the wire, loses exogenic action and does not kick-back, keeps having the unchangeable excellent performance of shape, plays the effect that the gauze mask is fixed on the bridge of the nose. And the outer layer 1 of the three-dimensional arch structure can leave enough space for the filter element 3, so that the filter element is not too close to the mouth and the nose of a wearer, the inconvenience of breathing is avoided, and the wearing comfort is improved.
As carbon dioxide exhaled by a wearer and water vapor can generate slight chemical reaction to generate carbonic acid, the carbonic acid is weakly acidic, the PH test paper interlayer is arranged in the filter element 3, and the water absorption layer, the PH test paper interlayer, the silver ion filtering layer and the waterproof layer are sequentially arranged from the face close to the wearer to the outside. The pH test paper interlayer can be used for detecting weak acidity generated by reaction of expiration and water vapor of a wearer, the size of the pH test paper interlayer can be designed according to the general respiration level of people by combining the area of the filter element 3 and required wearing time, when the color of the whole pH test paper interlayer is changed, if the color is changed from white to red, the wearing time of the mask is up, the filter element 3 needs to be replaced, and therefore the effect of indicating the wearing time is achieved.
Although specific embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these embodiments are merely illustrative and various changes or modifications may be made therein without departing from the principles and spirit of the invention, and therefore, the scope of the invention is defined by the appended claims.
