The technical scheme of the utility model is realized as follows:

a mining nasal air filter comprising: the pair of nasal plugs and the elastic band connected with the pair of nasal plugs are arranged, a connecting ring is fixed on the outer side of each nasal plug, a threaded shaft is fixed on the connecting ring, a threaded hole is formed in the pressure clamp, and the pressure clamp is connected to the threaded shaft; the inside of every nasal obstruction head is provided with the spacing ring, and the filter layer is pasted to the spacing ring outer end, and the filter layer outer end is located the lateral wall fixed connection post of nasal obstruction head, the fixed filter of the outer end of spliced pole.

Preferably, be provided with the screw hole on the filter, filter and spliced pole are through the connecting bolt connection.

Preferably, the outer side of the nose plug is sleeved with a rubber sleeve, and the pressure clamp is sleeved with the rubber sleeve.

Preferably, the opposite side walls of the pair of nasal plugs are respectively fixed with a clamping groove, a U-shaped clamp is fixed between the two clamping grooves, and the opening direction of the U-shaped clamp is consistent with the extending direction of the pressure clamp.

Preferably, the threaded shaft is provided with a rope belt.

Preferably, the nose plug is made of plastic, and the clamping groove is made of plastic.

The utility model has the beneficial effects that: the mining nose plug type air filter is small in size, the pressure clamp is in threaded connection with the threaded shaft, the direction and the clamping degree of the pressure clamp can be adjusted, and the use adaptability is improved. The two nasal plug heads are connected through the elastic band, so that the nasal plug is convenient to use. The two nasal plugs have double filtering functions and are directly plugged into the nostrils for use, so that the problem caused by large volume is completely avoided, and the nasal plugs are convenient to use.

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

FIG. 1 is a schematic overall structure diagram of a mining nasal air filter of the utility model;

fig. 2 is a schematic view of the internal structure of the nasal prong shown in fig. 1.

In the figure:

1. a nasal plug; 2. an elastic band; 3. a connecting ring; 4. a threaded shaft; 5. a pressure clamp; 6. a limiting ring; 7. a filter layer; 8. a filter plate; 9. a rubber sleeve; 11. a card slot; 12. a U-shaped clamp; 41. a rope belt.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example (b): a mining nasal air filter as shown in fig. 1 and 2, comprising: the nasal plug comprises a pair of nasal plugs 1 and an elastic band 2 for connecting the nasal plugs, wherein a connecting ring 3 is fixed on the outer side of each nasal plug 1, a threaded shaft 4 is fixed on the connecting ring, a threaded hole is formed in a pressure clamp 5, and the pressure clamp 5 is connected to the threaded shaft 4; the inside of every nasal obstruction head 1 is provided with spacing ring 6, and filter layer 7 is pasted to 6 outer ends of spacing ring, and 7 outer ends of filter layer are located the lateral wall fixed connection post of nasal obstruction head, and the fixed filter 8 in the outer end of spliced pole. The pressure clamp is in threaded connection with the threaded shaft, and meanwhile, the direction and the clamping degree of the pressure clamp can be adjusted, so that the use adaptability is improved. The filtering layer is stuck on the limiting ring, is arranged on the inner side of the nose plug and is not easy to be influenced, and the filtering layer can be replaced.

The filter 8 is provided with a threaded hole, and the filter is connected with the connecting column through a connecting bolt. The filter can be dismantled and connect, is convenient for wash. The outside of the nose plug is sleeved with a rubber sleeve 9, and the pressure clamp is sleeved with the rubber sleeve, so that the use comfort is improved. The nose plug is made of plastic.

The threaded shaft 4 is provided with the rope belt 41 and is used for being connected to other positions, such as a safety helmet, when the safety helmet is not used, the nasal plug head is directly pulled out, the nasal plug head is prevented from being lost, the nostril is inserted when the safety helmet is used, the use convenience is improved, and the nostril is prevented from being placed difficultly when the safety helmet is not used and is rapidly inserted when the safety helmet is used again. The opposite side walls of the pair of nasal plugs 1 are respectively fixed with a clamping groove 11, a U-shaped clamp 12 is fixed between the two clamping grooves, the opening direction of the U-shaped clamp is consistent with the extending direction of the pressure clamp, and the connection between the nasal plugs and the nostrils is further enhanced. The clamping groove is made of plastic materials, is consistent with the nose plug and is convenient to process.

When in use, the pair of nasal plugs are put into the nostrils, the pressure clips are clamped at the two sides of the nasal alars, and the U-shaped clips are clamped at the nasal root. If the U-shaped clamp of sensation can realize pressing from both sides tightly, extract the nose chock plug, rotate pressure clamp to other sides, reduce user's discomfort, do not influence other simultaneously. The pressure clamp and the U-shaped clamp are used simultaneously, so that the stability of the nose plug head during operation is enhanced. The coal dust is filtered through the outermost filter plate of the nose plug head, and the residual part is filtered through the filter layer, so that the coal dust is prevented from being directly sucked into the lung, and the sight line blockage and other influences caused by the large-size nose plug type air filter are avoided.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
