Description

The nostril dirt catcher

Technical field

The utility model relates to a kind of dustproof utensil, specifically, is the dirt catcher that is placed in the nostril.

Background technology

The nostril is the critical passage that pollutant enters human body in the outside air.Filter such as existing mouth mask, dust mask dirt instrument, shortcoming such as have that comfort level is bad, strainability difference and big or small length can't be regulated.

The utility model content

The purpose of this utility model is to overcome the deficiency of prior art, provide that a kind of strainability is strong, level of comfort good, can free adjustment, be installed in the dirt catcher in the nostril.

The utility model has left and right each dirt catcher, links together by the adjustable length connector; Each dirt catcher mainly is made up of protuberance guard, inner square, flexible adjustment tensioner ring, filter medium.Inner square is fixedlyed connected with the protuberance guard by inner square groove; The flexible adjustment tensioner ring is circular, is flexibly connected by broken ring and flexible adjustment expander to form, and this flexible adjustment tensioner ring is positioned at the below of inner square, and is fixed together with the edge, lower end of protuberance guard.

Said protuberance guard mainly is made up of grand shape grid cover, evagination point and interior prominent point, inner square groove, flexible adjustment expander slots, soft sealing ring.Load filter medium in the grand shape grid cover, the major function of this protuberance guard is to stop that filter medium is inhaled in the respiratory tract; Outer, interior prominent point on the grand shape grid cover---be used to increase the ventilation space between outer wall and nasal cavity face, inwall and filter medium; Inner square inserts in this inside square groove; The flexible adjustment tensioner ring inserts in the flexible adjustment expander slots; Soft sealing ring is fixed on the periphery of flexible adjustment tensioner ring.

Inner contact that said in-house network covers and mesh, its major function are to stop outside the dirt catcher of filter medium exhalation nostril; Interior prominent point can also increase the ventilation space between inwall and filter medium.

Said flexible adjustment tensioner ring is circular, mainly is made up of broken ring, flexible adjustment expander, and its major function is the soft sealing ring of expansion, makes it closely to contact with nasal wall, prevents that the nostril dirt catcher from dropping out from nasal cavity; Its broken ring---be used to expand soft sealing ring; Its flexible adjustment expander---be used to regulate the diameter of flexible adjustment tensioner ring.

Said adjustable length connector mainly is made up of connector, length adjuster, and its major function is the nostril distance according to different people, regulates the length between the dirt catcher of nostril, the left and right sides.

Said filter medium, its major function are the airborne floating dust things of adsorption filtration, can increase and decrease expense according to actual conditions, regulate filter densities.

The nostril dirt catcher of the utility model is a kind of to entering the airborne floating dust thing in nostril, effectively adsorbs and the stealthy healthy prevention articles for use that filter, make the structure novelty, safe and practical, strainability is strong, comfort level good, and the ground free adjustment that can vary with each individual.Simulated experiment proves: the utility model can filter 90% cigarette floating dust and 100% flour floating dust under comfortable breathing state.

The specific embodiment

Below in conjunction with embodiment of the present utility model of accompanying drawing narration

Present embodiment has left and right each dirt catcher, links together by adjustable length connector 5.Each dirt catcher mainly is made up of protuberance guard, inner square 2, flexible adjustment tensioner ring, filter medium.

Fig. 1 has shown the overall structure of nostril dirt catcher, is made of protuberance guard, inner square 2, soft sealing ring 3, flexible adjustment expander 4, adjustable length connector 5, connector 13.Fill filter medium in the protuberance guard, the lower opening of grand shape guard 1 in inner square 2 shutoff, prevents that filter medium from losing outward; The flexible adjustment tensioner ring is circular, is positioned at the below of inner square 2, is connected with the lower end of grand shape guard 1; Soft sealing ring 3 is fixed on the periphery of flexible adjustment tensioner ring, in order to improve the comfort level that flexible adjustment expander 4 and nasal wall closely contact; With about the connector 13 that links into an integrated entity of single nostril dirt catcher, the adjustable length connector 5 at its two ends can be used for regulating the distance between the dirt catcher of left and right single nostril.

Fig. 2 shown the protuberance guard structure, top mesh 6, interior prominent point 7, evagination point 8, inner square groove 9 are arranged, regulate and expand annular groove 10.Inner square 2 is fixedlyed connected with protuberance guard 1 by inner square groove 9; Adjusting expansion annular groove 10 is connected with the lower end of grand shape guard 1, and the flexible adjustment tensioner ring is fixed in this adjusting expansion annular groove 10; On two flexible adjustment expanders 4 about the two ends of connector 13 are fixed on, the other end of left and right two flexible adjustment expanders 4 is fixed on the flexible adjustment tensioner ring.
