Detailed description of the invention
Below just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.
As shown in Figures 1 to 6, a kind of hidden-type health respirator, especially, respirator passes in and out gas 2 attachings of having a stuffy nose by filter chamber box 1 and two of matching with human body nostril and forms, turnover gas nasal obstruction 2 communicates with filter chamber box 1 internal gas flow, and turnover gas nasal obstruction 2 is provided with and mate with human nasal vestibular internal mold the convex plug 21 rabbet, convex plug 21 makes to pass in and out gas and has a stuffy nose and 2 dock secure rigid with between human body nasal cavity, improves sealing.
Wherein, as shown in Figure 2, filter chamber box 1 dorsad air inlet side is provided with two stick harnesses 3, and turnover gas nasal obstruction 2 is detachably installed on stick harness 3 also fixing, dismountable turnover gas is had a stuffy nose 2 easy to use, can select suitable turnover gas nasal obstruction according to the nostril form of user and spacing.
For improving the sealing worn further, outside the plug wall of turnover gas nasal obstruction 2, be provided with the shirt rim 22 of more than one deck for respirator wearing state lower seal human body nostril.
In addition, as shown in Figure 3, filter chamber box 1 is the box body into and out of the two-way different time single-pass of air-flow, and filter chamber box 1 is provided with outlet valve 4, inlet valve 5 and air inlet filter core fixes guard 6, and inlet valve 5 and air inlet filter core are fixed between guard 6 and be provided with air filtering core 7.Be illustrated in figure 4 exhale, the structural representation of inlet valve, described inlet valve 5 is made up of base plate 51 and air-breathing silica gel piece 52, base plate 51 separates filter chamber box 1 one-tenth rear chamber B, front cavity A, and base plate 51 is provided with the suction hole 511 of a plurality of through two cavitys, air-breathing silica gel piece 52 be secured to base plate 51 dorsad rear chamber B side and with air pressure displacement close or discharge described suction hole 511; Outlet valve 4 is made up of expiration silica gel piece 42 and exhalation passages 41, exhalation passages 41 to be located in front cavity A and to be provided with a plurality of exhaling holes 411 be connected with air, and expiration silica gel piece 42 is secured to outside exhaling hole 411 and with air pressure displacement and closes or release exhaling hole 411; Under suction condition, exhalation passages 41 is closed and forward and backward cavity and turnover gas have a stuffy noses and 2 to be connected, and under expiration state, rear chamber B closes and passes in and out that gas has a stuffy nose 2, front cavity A is connected with exhalation passages 41.
Prevent from exhaling, air-breathing silica gel piece comes off, base plate 51 is provided with the air-breathing fixture 521 of restriction air-breathing silica gel piece 52 stroke, and exhalation passages 41 is provided with the expiration fixture 421 of restriction expiration silica gel piece 42 stroke.
Finally, air filtering core 7 is the multiplexing filter core that the PM2.5 of more than one deck filters that yarn, active carbon filtration layer or PM2.5 filter yarn and active carbon filtration layer, and filter effect is better.
During concrete enforcement, user selects applicable turnover gas nasal obstruction according to the nasal cavity shape of self and nostril spacing, then by using after turnover gas nasal obstruction and stick harness docking, turnover gas is filled in nostril namely to complete and wear, convex plug can link closely vestibulum nasi internal mold, anti-breather drops, and shirt rim improves sealing.After wearing, when the wearer inhales the air, filter chamber box inside is in negative pressure state, now outlet valve closes and inlet valve unlatching, expiration silica gel piece closes exhaling hole, air-breathing silica gel piece release suction hole, forward and backward cavity is connected with nasal obstruction of giving vent to anger, as shown in Figure 5, extraneous air enters rear chamber, along air inlet filter core fix guard laggard enter air filtering core filter, the clean clean air after filtration enters front cavity by the suction hole of base plate from rear chamber, then enters the nasal cavity of user along turnover gas nasal obstruction; When the wearer exhales the air, filter chamber box inside is in barotropic state, now outlet valve open and inlet valve close, air-breathing silica gel piece closes suction hole, expiration silica gel piece release exhaling hole, rear chamber is closed, front cavity, turnover gas nasal obstruction are connected with exhalation passages, and as shown in Figure 6, the waste gas that human body respiration is discharged enters front cavity through turnover gas nasal obstruction, then by discharging along exhalation passages after exhaling hole, air is entered.
Visible by describing above: to apply a kind of hidden-type health respirator of the present utility model and have the following advantages: respirator volume is little, and wear structure for hidden-type, do not affect the face recognition degree of user after wearing; The turnover gas nasal obstruction of respirator is provided with mates with human nasal vestibular internal mold the convex plug rabbeted, and wears firmly, and the good leak tightness between turnover gas nasal obstruction and nasal cavity; Do not need coated mouth, do not affect user's normal speech and dining.
The utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection domain of the present utility model.
