Fixation kit includes gas-tpe fitting, cassette tape, card bracelet, trachea one and trachea two, trachea one and trachea two are plugged on the trachea jack of nose cup respectively, gas-tpe fitting is three way cock, is plugged on trachea one and one end of trachea two, described cassette tape and cassette tape deduction of points and is not packed on the gas-tpe fitting of both sides.
Further, trachea one and trachea jack splicing position horizontal sextant angle are 5 ° ~ 15 °.
Further, trachea one and trachea jack splicing position horizontal sextant angle are 10 °.
Further, trachea two and trachea jack splicing position are 5 ° ~ 10 ° with horizontal sextant angle.
Further, trachea two and trachea jack splicing position horizontal sextant angle are 7 °.
Further, drainage screen is N95 material.
Further, mask is filter cotton material.
Further, mouth and nose protective cover also includes air cleaning facility, and described air cleaning facility is arranged on gas-tpe fitting one end of fixation kit by trachea.
This utility model uses nose cup and mask can flip up to front shroud surface, solve the problem being inconvenient to take food or talk when wearing, the sealing gasket of nose cup fits tightly with the position of nasal contact, breathed by the passage of front shroud, nose key protection as respiratory apparatus is lived by nose cup, and filtering material not with direct body contact, make nose cup inner air flow more preferable, the structure of moisture damage filtering material when will not make breathing, utilizing filtering material efficiently, meanwhile, filtering material is removable, economical environment-protective, the repeatable utilization of nose cup；This utility model can pass through the device such as trachea plug and connecting tube, accesses air purifier, realizes air cleaning with this.
