Abstract
The utility model discloses an invisible U-shaped filter. The invisible U-shaped filter comprises two nose plug bodies which are connected through a connecting rod, wherein each nose plug body comprises an outer cover and an inner cover; each of the outer cover and the inner cover is provided with a vent hole respectively; each of the outer cover and the inner cover consists of an outer surface layer and a filter layer respectively; the filter layers are made of viscose TPR (thermoplastic rubber); and the connecting rod is made of transparent PP. Through interaction of the outer cover and the inner cover, dust particles in air can be effectively filtered out; both the outer cover and the inner cover are provided with the vent holes respectively, so that when the invisible U-shaped filter is put on, air circulation is smooth, without affecting respiration; when the invisible U-shaped filter is required to be used, the two nose plug bodies are required to be plugged into nares only, so that the invisible U-shaped filter is convenient and quick; furthermore, the connecting rod is made of transparent PP, as a result, the invisible U-shaped filter is difficult to find out, thereby achieving invisible effect and not affecting overall appearance.
Description
Technical field
The utility model relates to a kind of breathing apparatus, particularly a kind of stealthy U filter.
Background technology
At present, air quality worse and worse, people adopt usually the band mouth mask mode protect oneself, thereby avoid sucking a large amount of dust granules.But unsmooth breath when wearing mouth mask, and influence attractive in appearancely used in season of sweltering heat or area, had certain limitation, and the effect that hides of mouth mask is very limited in addition, poor effect; In the use, the mouth mask both sides are provided with hanging support, collude and are hung on ear, influence each other with eyes, cause and wear uncomfortablely, it wears the normal interchange that mouth mask influences the people again, such as traffic police and traffic management assistant, dust is more on road, need wear mouth mask, is being in an emergency need blow a whistle the time, must take mouth mask, use inconvenience.
The utility model content
The purpose of this utility model is to provide a kind of novel stealthy U filter.
According to one side of the present utility model, a kind of stealthy U filter is provided, comprise two nasal obstruction bodies that connect by connecting rod, the nasal obstruction body comprises outer cover and inner cover, outer cover and inner cover are equipped with passage, outer cover and inner cover are formed by extexine and filter course, and filter course is made by viscosity TPR (thermoplastic elastomer) material, and connecting rod is made by transparent PP (polypropylene) material.Thus, when needing to use, only need to bring two nasal obstruction bodies into nostril and get final product, easy to use.In use, airborne dust enters the nasal obstruction body, earlier the filter course by inner cover is adsorbed in dust on the filter course, and air enters outer cover after by inner cover, and the filter course of outer cover carries out second adsorption, so reach the function of twice filtration, dust granules in the filtered air, and outer cover effectively and inner cover all have passage, make when wearing, be convenient to air and reflux, can not influence breathing; Connecting rod is made by the transparent PP material in addition, is difficult for finding, thereby reaches stealthy effect, can not influence overall appearance.
In some embodiments, the filter course of inner cover is provided with via hole, is provided with filter block and first filtering rod around its via hole.Thus, be provided with via hole convenient with being connected of outer cover, filter block and first filtering rod make that the filter effect of inner cover is better.
In some embodiments, the filter course of outer cover is provided with holddown groove, is provided with second filtering rod around the holddown groove.Thus, the structure of " bowl " shape makes outer cover can wrap up inner cover, can enter the filter course of outer cover after air is by inner cover; Holddown groove is used for fixed connecting rod, and second filtering rod increases the filter effect of outer cover.
In the something real mode, inner cover is loop configuration, and outer cover integral body is " bowl " shape, and its inside is provided with the cavity that holds inner cover.Thus, convenient combination and dismounting.
In some embodiments, the connecting rod middle-end is " U " type.The both ends of connecting rod are provided with bulge loop.Thus, the nostril is pressed close in the design of " U " type more, make when wearing more comfortable and attractive in appearance, more firm when bulge loop make to be pegged graft.
In some embodiments, extexine is made by TPE (thermoplastic elastomer (TPE)) material.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 to Fig. 5 has schematically shown the stealthy U filter according to preferred embodiment of the present utility model.
According to one side of the present utility model, a kind of stealthy U filter is provided, comprise two nasal obstruction bodies 2 that connect by connecting rod 1.Connecting rod 1 is made by the transparent PP material and its both ends are provided with for what peg graft and are provided with bulge loop 101, and the middle-end of connecting rod 1 is " U " type as shown in Figure 2, so makes the utility model connecting rod 1 when wearing can press close to the nostril more, and is more comfortable and attractive in appearance.
Stealthy U filter of the present utility model, nasal obstruction body 2 is pegged graft by the two ends of connecting rod 1, form " U " type structure as shown in Figure 1, only need that when using two nasal obstruction bodies 2 are filled in the nostril and get final product, convenient and swift, and during use only the middle-end of connecting rod 1 expose outside the nostril, and connecting rod 1 is made by transparent BB material, be difficult for finding, thereby reach stealthy effect, can not influence overall appearance.In use, airborne dust enters nasal obstruction body 2, by the filter course 204 of inner cover and filter block 206 and first filtering rod of being located on the filter course 204 207 dust is adsorbed earlier, air enters outer cover 201 by first passage 2021 of inner cover, the filter course of outer cover 201 and second filtering rod 208 that is provided with carry out second adsorption, so reach the function of twice filtration, dust granules in the filtered air effectively, and outer cover 201 and inner cover all have passage, make when wearing, be convenient to air and reflux, can not influence breathing.
