Abstract

A nose protection cover, which comprises a bear frame covered with soft coating and the filter material, the shape size adapts with the human body nose, the contour is similar to the human body nose and can be wear on the nose; when used, the soft coating also well adapts the nose that the nose shape is of slight difference; people can breathe the fresh air filtrated once the nose protection cover is wear. The unidirectional respiration valve can also be opened with the airway connection to the highly effective filter to obtain the better protection effect; the airway can be moderately lengthened and put into the warm clothes inside in winter; the own volumetric heat used can reduce the ice-cold air stimulation to the breathing organ. The utility model has good protective function to the respiratory tract patients like the rhinitis patients, etc, and the fresh cool air can be breathed in summer under the burning hot climate by covering the ice bag on the airway.

Description

Protective nose cover

Affiliated technical field

The utility model relates to a kind of air filter, is meant a kind of protective nose cover that is worn on the nose especially.

Background technology

Automobile is more and more in the modern city, the tail gas that wagon flow produces, the health that dust is threatening the pedestrian constantly, resemble especially traffic-police, by bike on and off duty etc. some place oneself in the midst of personnel among tail gas and the dust, be starved of the harm that a kind of convenient effective respiratory protection apparatus comes blocking harmful gas and dust.Nasal cavity is people's a main external respiration passage, if can carry out the protection to nose, just can effectively prevent, alleviate air pollution to the harm of human body.Existing mouth mask, breathing mask etc. because of wear with exchange be inconvenient to use limited, existing nose cup is not extensive use of in daily life because of some shortcomings yet, as the patent No. is that the anti-dust nose mask of 200420061930.X can make breathing smooth inadequately, the patent No. is 200420034767.8 the not enough light and beautiful of a kind of anti-dust nose mask, and it is too complicated that the patent No. is that 92231815.8 light-duty nose covering type is filtered light device structure.

Summary of the invention

The utility model provides a kind of protective nose cover, by the protection to the human nose, stops harmful substances such as waste gas, dust to enter human body internal respiration road from nasal cavity, and this protective nose cover volume is small and exquisite attractive in appearance, easy to use, can allow the people breathe smoothness simultaneously.

The technical scheme that the utility model adopted is: a kind of protective nose cover, comprise support and cover body, it is characterized in that support protects lining by hard material frame part outsourcing one deck flexible material and makes, its shape size adapts with the human nose, can be worn on the nose, cover body is made by filtering material, size shape and support adapt, protective nose cover global shape size adapts with the human nose, profile is similar to the human nose, can have small sucker on the support, the gluing face, firm facility such as protecting band or nose clip is put on protective nose cover and can be breathed through filtered air during use.

Described cover body can be offered one to a plurality of one-way breather valves that can only outwards exhale, so that breathe more unobstructed.

One-way breather valve and the one-way sucting valve that one or more can only unidirectional ventilation be made and be offered to described cover body also can by permeable material not, inlet valve has wireway to stretch out, the wireway other end can connect high efficiency particulate air filter or oxygen cylinder etc., wireway can be worked as protecting band and be tied up on head, its length can be longer, it is warming can suck warm air to inject the clothes the inside winter, and summer can be at the outer wrapping ice bag can suck pure and fresh pleasantly cool air.

Major advantage of the present utility model is: simple in structure, good looking appearance, easy to use; can use in daily life; to reduce the injury of air pollution to human body, can also play a protective role to nose, be fit to rhinitis and breathing problem patient and use for a long time.

1. supports among the figure, 2. cover body, 3. one-way breather valve, 4. one-way sucting valve, 5. notch.

The specific embodiment

Implementation column 1: as Fig. 1, shown in Figure 2, protective nose cover is made of support 1 and cover body 2, support 1 by pliability preferably wired frame make, its shape size adapts with adult's nose, can be worn on the nose, and protect lining in the soft filtration sponge of framework and skin contact part subpackage one circle, cover body 2 is made by the board-like preferably filtering material of permeability, cover body 2 shapes size adapts with support 1 and the edge closely is sticked together, protective nose cover global shape and human nose adapt and appearance similar, the gluing face that one deck and skin-friendly bond property are arranged at support 1 and skin contact, when being worn over protective nose cover on the nose, on the support 1 soft filter cotton both can allow nose shape slightly poor others also can coincide with protective nose cover, can not produce the space, filter cotton can also have certain firm effect to the extruding and the friction of nose simultaneously, adds the absorption affinity of gluing face, protective nose cover better is stabilized on the nose, so just can breathes fresh air through filtering.

Implementation column 2: as shown in Figure 3, on the basis of embodiment 1, cover body is made by the better filtering material of filter effect, and on cover body, offer the one-way breather valve that outwards to exhale, when using, the gas that sucks enters nasal cavity through filtering bodies, and the gas of exhalation discharges through outlet valve, plays filter effect.

Implementation column 3: as shown in Figure 4, on the basis of embodiment 1, cover body is made by impermeable frivolous plastics, on cover body, offer simultaneously 2 one-way sucting valve and the one-way breather valves that can only outwards exhale that can only suck gas, on one-way sucting valve, respectively there is a wireway to stretch out, wireway can be worked as protecting band and be tied up at (on the support shouldn't gluing face) on the head, and can merge into an interface and connect other wireways, connect a portable filter efficiently by wireway during use, just can play protective action preferably.Wireway also can suitably extend; allow winter wireway pass warm clothes nexine; can reduce of the stimulation of ice-cold air, respiratory tract patients such as rhinitis are had the better protect effect, allow summer the part of wireway can also suck pure and fresh pleasantly cool air by portable ice bag to respiratory apparatus.

Claims
