Description

A kind of anti-dust nose mask

Technical field

The present invention relates to the anti-dust respirator for human body, more particularly to a kind of anti-dust nose mask.

Background technology

In recent years, being continually changing with natural environment, atmosphere pollution and weather conditions increasingly deteriorate, to the body of the mankind Body health produces harmful effect.Particularly haze weather increases year by year, and rhinitis, flu, pharyngitis, bronchial astehma, pneumonia etc. are exhaled The incidence of disease for inhaling tract disease is significantly raised.Nasal cavity, as the entrance of respiratory tract, is the key of human lung's protection, but for air In superfine dust and pernicious gas, nasal cavity can not be effectively isolated filtering.At present, conventional dust-proof means are exactly to wear masks, By using hair band or hang over the tether on ear and fix.

But, there is following defect in existing anti-dust respirator：

Although masked area is big but effective usable floor area is small, only there is screening dirt to prevent in the range of the small area positioned at nose and mouth Dirt is acted on；The poor air permeability under hot season or hot environment, there is obvious sense of discomfort, is difficult to be received；It is specific at some Environment in, wear that mouth mask is very inconvenient, such as the manager of building site commander, attend class using on the teacher of chalk, road using pair Say traffic police of machine etc..

The content of the invention

In order to overcome the deficiencies in the prior art, it is an object of the invention to provide a kind of compact structure it is light, easy to use, The anti-dust nose mask of comfortable wearing.

The purpose of the present invention is realized using following technical scheme：

A kind of anti-dust nose mask, including main body, support, filter screen and filtering bodies, the main body include cup, and the support is housed In the cup, the filter screen is located between the cup and the support, and the support is hollow cylinder, the filtering bodies card The internal stent is put in, is discharged into the gas in the support after the filtering bodies and/or the strainer filtering.

Further, the support is made of ebonite material, and the main body is made of flexible glue material, the cup bag The collar is included, the collar is socketed on outside the support.

Further, the main body also includes connector, the connector in circular or U-shaped, the connector with The cup is fixedly connected.

Further, the cup includes the collar, shell and groove, and the collar is socketed on the support, the shell Axis overlapped with the axis of the collar, the groove is located at the junction of the shell and the collar.

Further, the filter screen one end open, other end closure, outwards turnover forms flanging for described support one end, institute Screen port side pressure is stated together between the flanging and the groove bottom land.

Further, the support other end is provided with chamfering.

Further, the filtering bodies are made up of absorption activated carbon particle, and the filter screen is made up of filter cotton.

Further, the rack side wall be provided with stomata, the stomata be ellipticity, it is circular or square in one kind or It is a variety of.

Further, the length of the filtering bodies is less than the length of the support.

Further, the anti-dust nose mask is axially symmetric structure.

Compared with prior art, the beneficial effects of the present invention are：The filtering to gas is realized by filter screen and filtering bodies, is risen To the effect of dust-proof anti-haze；Main body is socketed on support, and filter screen is set between support and main body, simple in construction compact, facilitates insertion into Nasal cavity；Filtering bodies card is placed on internal stent, is conveniently replaceable.

Embodiment

Below, with reference to accompanying drawing and embodiment, the present invention is described further, it is necessary to which explanation is, not Under the premise of afoul, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination Example.

As Figure 1-4, a kind of anti-dust nose mask, including main body 10, filter screen 20, support 30 and filtering bodies 40, are an axle pair Claim structure.

Main body 10 is made of soft silica gel material, with environment-protecting and non-poisonous, soft comfortable, easily the characteristic such as cleaning.Main body 10 Including two cups 11 and connector 12.Cup 11 includes the collar 13 and shell 14, axis and the axis of shell 14 of the collar 13 Line is overlapped, and the junction of the collar 13 and shell 14 forms groove 15, and air cavity 16 is formed between the collar 13 and shell 14.Connector 12 In circular or U-shaped, the two ends of connector 12 are fixedly connected with two cups 11 respectively.In the present embodiment, the one of main body 10 into Type.

Filter screen 20 is made of filter cotton such as non-woven fabrics, good permeability, the dust being used in air filtering.The one end of filter screen 20 Opening, other end closure.

Support 30 is hollow circular cylinder, is made of hard plastic glue.The side wall of support 30 is provided with some stomatas 31, and stomata 31 is random It is distributed or is uniformly distributed, stomata 31 is the one or more in elliptical aperture, circular hole or square hole.One end outward bending of support 30 Flanging 32 is formed, the other end is provided with chamfering 33.

Filtering bodies 40 are made up of adsorbable filtering material such as activated carbon, and the card of filtering bodies 40 is put in inside support 30.Due to Main body 10 is made of flexible glue material, and support 30 is made of ebonite material, and during assembling, the collar 13 in cup 11 is socketed in branch On frame 30, support 30 is set to be contained in cup 11, now, the flanging 32 of support 30 is abutted with the bottom land of groove 15.The opening of filter screen 20 Hold and be fixed under the pressing effect of support 30 and main body 10 between main body 10 and support 30.

In use, cup 11 is inserted nasal cavity by hand-held connector 12, air cavity 16 is set to be connected with respiratory tract.Extraneous air enters Inside support 30, portion of air is discharged after being filtered through filtering bodies 40 from the stomata 31 on support 30, then after the filtering of filter screen 20 Into air cavity 16.Another part air is filtered after directly being discharged from the stomata 31 on support 30 through filter screen 20 enters air cavity 16.Gas Body enters after air cavity 16, is inhaled into respiratory tract, and during being somebody's turn to do, harmful substance is attracted to filter screen 20 and filtering bodies 40 in gas On, and then stimulation of the dust to respiratory tract in air is reduced, reduce the generation of breathing problem.

Filtering bodies 40 in the anti-dust nose mask can be changed, support 30 and the cleaning easy to disassemble of filter screen 20, help to repeat Use.The size in human body nostril has differences, therefore cup 11 can be designed to different sizes.The design of connector 12 is easy to Extract anti-dust nose mask out out of nasal cavity.The length of filtering bodies 40 is shorter than the length of support 30, makes filtering bodies 40 and is not filled by whole branch The inner space of frame 30, contributes to being smoothed out for breathing, reduces respiratory resistance.

Above-mentioned embodiment is only the preferred embodiment of the present invention, it is impossible to limit the scope of protection of the invention with this, The change and replacement for any unsubstantiality that those skilled in the art is done on the basis of the present invention belong to institute of the present invention Claimed scope.
