Abstract
The utility model relates to a respirator made the reseau face cloth as the carriage, composed of a filter cover, a reseau frame layer is arranged in the outward the filter cove, the reseau frame is jointed with the filter cove, fastening ties are respectively connected with the two sides of the filter cove. Because the utility model arranges a reseau frame outward the filter cove, increasing the healing capability after respirator extrusion, increasing the intensity of the respirator, so prolong the actual useful life, and because an active carbon grain filter layer is arranged is arranged between the filter cove and the reseau frame, effectively reducing the respiratory resistance, make the customer more brisk and comfortable.
Description
Technical field:
The utility model relates to the mankind life article, relates in particular to the security protection articles for use, particularly mouth mask, and concrete is a kind of mouth mask of making bracing frame with grid surface cloth.
Background technology:
In the prior art, security protection is made of face shield and frenulum with mouth mask, and face shield is made of the filtration case of a solid shape, and the material that filters case adopts nonwoven or PP material, filters the common similar hemisphere of shape of case, and frenulum is connected the both sides of face shield.In the use, will filter case and hide mouth and nose, strap loop is fixed face shield around head, and is air-breathing and when exhaling, and air all sees through the material gap of filtering in the case and passes in and out.But this mouth mask through extruding after, easy deformation, and resilient not make reduce the service life of mouth mask.Secondly,, increased respiratory resistance, made the wearer feel vexed and unhappy because the cloth matter of face cloth is tight.
Summary of the invention:
The purpose of this utility model is to provide a kind of and makes the mouth mask of bracing frame with grid surface cloth, the described this mouth mask of making bracing frame with grid surface cloth to solve in the prior art mouth mask through extruding back easy deformation, non-resilient, service life is short and the wearer feels vexed and unhappy technical problem.
This mouth mask of making bracing frame with grid surface cloth of the present utility model filters case by one and constitutes, the arranged outside of described filtration case has one deck grid frame, described grid frame is made of grid surface cloth, grid frame and described filtration case are fitted and connected, and the position, both sides of described filtration case is connected with restraint zone respectively.
Further, between described filtration case and described grid frame, also be provided with a filter course, evenly be provided with activated carbon granule in the described filter course.
Further, the both sides of described restraint zone and described filtration case are connected by a buckle structure.
Further, described buckle structure is made of a framework, one side of described framework is connected with described filtration case, a groove is set in the described framework, be provided with a flexure strip in the described groove, an end of described flexure strip is fixedlyed connected with described framework, and the other end of flexure strip is wedge type, the length in the outside of flexure strip is greater than the length of inboard, and the length in the outside of flexure strip is more than or equal to the length of described groove.
Further, the described filtration case left and right sides is set with a unidirectional valve of giving vent to anger respectively.
Further, described two unidirectional valves of giving vent to anger are that axial symmetry distributes with the vertical line through described filtration case middle part.
Further, the middle part of described filtration case is set with a unidirectional valve of giving vent to anger.
Further, the edge along described filtration case is set with a circle cushion pad.
Further, described cushion pad is made of the foaming thing.
Further, described grid frame has elasticity.
Concrete, filtration case described in the utility model, the unidirectional valve of giving vent to anger, restraint zone and foaming thing all adopt known technology of the prior art, about filtering case, the unidirectional valve of giving vent to anger, restraint zone and foaming thing known solution in the prior art, those skilled in the art all understands, does not repeat them here.
Operation principle of the present utility model is: will filter case and hide mouth and nose, and utilize restraint zone around head face shield to be fixed.The cushion pad that fixedly installs along the opening part edge that filters case can strengthen the effect that is sealed and matched of filtering case and human body face.When air-breathing, air sees through the material gap of filtering in the case and enters, during expiration, breath is discharged to by the unidirectional valve of giving vent to anger and filters outside the case, accelerated the inside and outside exchange velocity of air, a part of waste gas has been reduced the time of staying of breath in filtering case by charcoal absorption, reduce humidity in the filtration case, ensured the freshness of skin of face health and suction air.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model because in the arranged outside of filtering case one deck grid frame, increased the restorability after mouth mask pushes, strengthened the intensity of mouth mask, therefore also prolonged the physical life of mouth mask, owing between described filtration case and described grid frame, also be provided with one deck the activated carbon granule filter course is arranged again, the waste gas that makes the user discharge can be as soon as possible by charcoal absorption, guaranteed that the user breathes ozone, the utility model is provided with the unidirectional valve of giving vent to anger on the filtration case simultaneously, discharge the filtration case rapidly by unidirectional air outlet valve goalkeeper breath, accelerated the inside and outside exchange velocity of air, reduced the time of staying of breath in filtering case, reduce humidity in the filtration case, ensured skin of face health.Simultaneously, cushion pad is set, has strengthened the effect that is sealed and matched of filtering case and human body face along the opening part edge that filters case.Because the filter course outside is a grid surface cloth, reduces respiratory resistance, makes the wearer more feel easily comfortable.
