The purpose of this utility model is realized using following technical scheme：

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

Further, the cup includes the collar, and 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 also includes shell and groove, and the collar is socketed on the support, in the shell Axis overlaps with the axis of the collar, and 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 rack side wall is provided with stomata, the stomata be ellipticity, circle or it is square in one kind or It is a variety of.

Further, the length of the filtering body 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 utility model are：The mistake to gas is realized by filter screen and filtering body Filter, plays a part 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, is easy to Insert nasal cavity；Filtering body card is placed on internal stent, is conveniently replaceable.

Embodiment

Below, with reference to accompanying drawing and embodiment, the utility model is described further, it is necessary to explanation is, On the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new Embodiment.

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

Main body 10 is made of soft silica gel material, has 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 overlaps, 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 both 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 body 40 is made up of adsorbable filtering material such as activated carbon, and the card of filtering body 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, the flanging 32 of support 30 is set to be abutted with the bottom land of groove 15, so as to the connection of realization body 10 and support 30.Filter screen 20 Openend is fixed between main body 10 and support 30 under the pressing effect of support 30 and main body 10.

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 the filtering of filter body 40 from the stomata 31 on support 30, then after the filtering of filter screen 20 Into air cavity 16.Another part air filters after directly being discharged from the stomata 31 on support 30 through filter screen 20 enters air cavity 16.Gas After body enters air cavity 16, respiratory tract is inhaled into, during being somebody's turn to do, harmful substance is attracted to filter screen 20 and filtering body 40 in gas On, and then stimulation of the dust to respiratory tract in air is reduced, reduce the generation of breathing problem.

Filtering body 40 in the anti-dust nose mask can be changed, and 20 cleaning easy to disassemble of support 30 and filter screen, 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 body 40 is shorter than the length of support 30, makes filtering body 40 and is not filled by entirely propping up The inner space of frame 30, contribute to being smoothed out for breathing, reduce respiratory resistance.

Above-mentioned embodiment is only preferred embodiment of the present utility model, it is impossible to is protected with this to limit the utility model Scope, the change of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacing belongs to In the utility model scope claimed.
