Abstract
The invention relates to a protective mask with a drainage valve, and belongs to the field of labor insurance protective equipment. The protective mask is composed of an outer cover plate, a mask body, a filter, an inhalation valve, an exhalation valve and the drainage valve. The inhalation valve is installed in the front of the mask body. The filter is installed in front of the inhalation valve. The outer cover plate is installed in front of the filter. The inhalation valve is installed at the lower portion of the mask body. The drainage valve is installed at the bottom of the mask body. The drainage valve is composed of a drainage valve body and a drainage valve element. The drainage valve is installed at the lowest position of the protective mask in the working state; when water is gathered inside the protective mask, water can be directly drained out of the mask through exhalation; during inhalation, the drainage valve can be rapidly turned off through air flow flowing through a gap of a drainage valve plate. The problems that when an existing protective mask is used at low temperature and particularly used in a cold place, condensate water inside the mask will affect the valve plate of a respirator inside the mask and particularly affect turning-on and turning-off of the exhalation valve, the sealing performance is poor, leakage is caused, and the gas defense effect of the protective mask is affected are solved.
Description
Technical field
The present invention relates to a kind of protective face mask with draining valve, belong to labor protection articles for use field.
Background technology
Existing protection face be covered with helmet-type, hood type, every various structures such as filter formulas, because protective face mask is all generally use under mephitical environment, what therefore hope and face were fitted is more tight better, and the respiratory tract preventing poison gas from directly entering people from contact gap causes human injury.But so bring again a new problem, when people use protective face mask to carry out exhaling or air-breathing time, when particularly using in the place of cold, the gathering of the liquid such as condensate water can be produced, to the respirator valve block, particularly outlet valve of face masks in face masks, due to particles such as outlet valve outside meeting dust exposures, cause outlet valve opening and closing influenced with after the inner liquid mixing produced, cause poor sealing to be revealed, affect the gas defence effect of protective face mask.Time serious, face shield bottom also can form ponding by user's suction inlet, affects the normal use of protective face mask.
Summary of the invention
The object of the invention is to, for above-mentioned the deficiencies in the prior art, provide a kind of extreme lower position being positioned at protective face mask duty to be provided with draining valve, its discharge structure is normally open, directly can derive mask exterior when there being liquid accumulation; When exhaling, portion gas is formed to wash away by draining space and ensures the clean and tidy of water trap, and air-flow when flowing through draining valve block gap when air-breathing produces bernoulli effect, enables the protective face mask of the band draining valve of draining valve quick closedown.
The present invention realizes above-mentioned purpose by following technical solution:
The protective face mask of this band draining valve is made up of outer cover plate, mask body, filter, inlet valve, outlet valve and draining valve, it is characterized in that: be provided with inlet valve before mask body, is provided with filter before inlet valve, be provided with outer cover plate before filter; The bottom of mask body is provided with outlet valve; The bottom of mask body is provided with draining valve.
Described draining valve is made up of draining valve body and drain plug, and the center of draining valve body is manufactured with central through hole, and outer surface is manufactured with fixed card slot; The upper end of drain plug is manufactured with upper cone, and lower end is manufactured with lower cone; Draining valve body is installed on the bottom of mask body by fixed card slot, and drain plug is inserted in the central through hole of draining valve body, has gap between drain plug and central through hole, and drain plug is movably fixed on draining valve body by upper cone and lower cone.
The top of the central through hole of described draining valve body is manufactured with the uniform axial flow hole of a circle, and the bottom of central through hole is made into horn mouth.
Internal taper hole is manufactured with in the lower cone of described drain plug.
Described draining valve is arranged according to the space of protective face mask, is positioned at the extreme lower position of protective face mask duty, and the discharge structure of draining valve is arranged to normally open.
Described draining valve body is made up of flexible plastic or rigid plastics according to service condition difference, and when using flexible plastic to make, draining valve body can directly and mask body one-shot forming.
The present invention compared with prior art has following beneficial effect:
The extreme lower position that protective face mask is being positioned at protective face mask duty of this band draining valve is provided with draining valve, is directly discharged to mask exterior when having water to assemble in protective face mask by exhaling; And when exhaling, portion gas is formed to wash away by draining space and ensures the clean and tidy of water trap, and air-flow when flowing through draining valve block gap when air-breathing produces bernoulli effect, enables draining valve quick closedown.Use under solving existing protective face mask low temperature, when particularly using in the place of cold, the opening and closing of the condensate water in face shield to the respirator valve block, particularly outlet valve of face masks impacts, cause poor sealing to be revealed, affect the problem of protective face mask gas defence effect.
