Described filter membrane is the film with air pollutants filtering function, as HEPA(High efficiency particulate air Filter, highly effective air particle filtering) film etc.
Described nasal cavity hole sticking machine employing medical silica-gel etc. has no side effect and has good flexible material human body and makes.Nasal cavity hole sticking machine is divided into two of left and right, for fitting with nasal cavity hole, two of left and right of human body.Nasal cavity hole sticking machine runs through the cavity that a hollow sphere forms for a hollow circular cylinder.Cavity profile designs according to bionics principle, simulation human nasal lumen pore.In cavity inside, the hollow space of hollow circular cylinder and hollow sphere forms an overall hollow communicating structure, and the smooth and easy breathing of this structure can be passed through in nasal cavity hole.Nasal cavity hole sticking machine in use, insert in nasal cavity hole by a part for cavity, and another part is stayed outside nasal cavity hole, and cavity and the similar profile of human nasal lumen pore have ensured that the part that cavity inserts in nasal cavity hole can fit tightly with nasal cavity hole.Hollow circuit cylinder external surface has two circular protrusions, forms an annular groove between projection.
When the miniature individual gas defence dirt mask of mask type uses, nasal cavity hole sticking machine and filter membrane sealing-in.The air of nasal cavity hole incoming call all passes through the filtration of filter membrane, utilizes filter membrane to remove the particularly particulate pollutant of pollutant in air amount.Common mouth mask covers on outside nasal cavity hole sticking machine and filter membrane, has effect attractive in appearance, can also play preliminary filtration air amount, support the effects such as nasal cavity hole sticking machine.
The miniature individual gas defence dirt mask of mask type that the utility model is related, can fit tightly complete airtight nasal cavity hole with human nasal lumen pore, realize particularly effective filtration of particulate pollutant of pollutants in air, biomimetic features based on nasal cavity hole sticking machine design simultaneously can greatly alleviate the discomfort such as feeling oppressed of user, is suitable for using for a long time in air pollution environment.
Brief description of the drawings
Fig. 1 is the front view of nasal cavity hole sticking machine section.(the digital unit marking in figure is millimeter, and R represents radius, and Φ represents diameter.The digital not strict conformance of ratio corresponding relation of the concrete size of the lines of drawing and mark in figure, is as the criterion with the numeral of mark while implementing the utility model.）
Detailed description of the invention
With embodiment, detailed description of the invention of the present utility model is described below, but the utility model is not limited to following embodiment.
Embodiment:
The miniature individual gas defence dirt mask of mask type, comprises common mouth mask, filter membrane and nasal cavity hole sticking machine.
Nasal cavity hole sticking machine is divided into two of left and right.Nasal cavity hole sticking machine runs through the cavity that a hollow sphere forms for a hollow circular cylinder.The overall diameter 10-13 millimeter of hollow circular cylinder bottom surface, preferably 11 millimeters.Hollow circuit cylinder height 16-20 millimeter, preferably 17 millimeters.The outer radius 6-7 millimeter of hollow sphere, preferably 6.5 millimeters.Cavity profile designs according to bionics principle, simulation human nasal lumen pore.In cavity inside, the hollow space of hollow circular cylinder and hollow sphere forms an overall hollow communicating structure, and the smooth and easy breathing of this structure can be passed through in nasal cavity hole.The interior diameter 8-10 millimeter of hollow circular cylinder bottom surface, preferably 9 millimeters.The inside radius 5-6 millimeter of hollow sphere, preferably 5.5 millimeters.Hollow circuit cylinder external surface has two circular protrusions, forms an annular groove between projection.Bottom surface of hollow circular cylinder is apart from the junction 2-3 millimeter of hollow circular cylinder and hollow sphere, and a circular protrusion is close in another bottom surface.Two circular protrusions measure-alike, is overall diameter 14-15 millimeter, thickness 0.8-1 millimeter.Distance 0.8-1.2 millimeter between two circular protrusions.The structure of nasal cavity hole sticking machine as shown in Figure 1.The size of hollow circular cylinder and hollow sphere is according to the size design of human nasal lumen pore, and its preferred value is according to most people's nasal cavity hole dimension design.
Filter membrane can be one or more.If a filter membrane is folded to form two sides and uses, if the stacked use of multiple filter membranes can form a cavity like this between filter membrane.For ease of forming cavity, a side of filter membrane (while using a filter membrane, refers to a side of this filter membrane; While using multiple filter membranes, refer to wherein two filter membranes side separately) on have supporter, the formation that supporter can support cavity.This cavity structure has further improved the smoothness that breathe in nasal cavity hole.Supporter can use plastic strip or other materials to make.For example, utilize plastic strip to form symmetrical projection on a side of a filter membrane, after this filter membrane folds and four limits are sealed, symmetrical projection is conflict mutually, forms cavity between filter membrane.The surface of filter membrane is porose, bore edges has snap ring, snap ring interior diameter is identical with the overall diameter of nasal cavity hole sticking machine hollow circular cylinder, snap ring overall diameter is than the large 8-20 millimeter of its interior diameter, the distance identical or smaller (both gaps are less than 0.2 millimeter) between snap ring thickness and two circular protrusions of nasal cavity hole sticking machine hollow circuit cylinder external surface.Snap ring can adopt the material such as plastics, rubber to make.
Nasal cavity hole sticking machine supports the use with the film formed cavity of filtration.Supporting mode can be a supporting cavity of nasal cavity hole sticking machine, and now the surface of every filter membrane only has a hole; Also can be two supporting cavitys of nasal cavity hole sticking machine, now there be two holes on the surface of every filter membrane, and two hole circles distance is in the heart with reference to distance design in the heart in human nasal lumen pore.
The present embodiment mask before use, first filter membrane is folded to form to cavity, again the circular protrusion of being close to hollow circular cylinder bottom surface on the nasal cavity hole sticking machine of two of left and right is inserted in the hole of filter membrane surface, make two grooves between circular protrusion block snap ring (because hollow circular cylinder has certain elasticity, this operation can realize).When user wears, nasal cavity hole sticking machine is not connected in all or part of insertion nasal cavity hole, one end of filter membrane, fit tightly with nasal cavity hole, and regulate the position of nasal cavity hole sticking machine to realize comfortable wearing.Common mouth mask covers on outside nasal cavity hole sticking machine and filter membrane, has effect attractive in appearance, can also play the effect of supporting nasal cavity hole sticking machine.
The present embodiment filter membrane has certain service life, can change after reaching service life.After nasal cavity hole sticking machine uses, carry out cleaning and sterilizing with sanitizers such as ethanol for disinfection, can prolonged and repeatedly use.
