Description
Technical field
The present invention relates to a kind of protective face mask with draining valve, category labor protection articles for use field.
Background technology
Existing protection face is covered with helmet-type, hood type, every various structures such as filter formulas, because protective face mask is typically all
Used under mephitical environment, it is more tight better it is desirable to what is be bonded with face, prevent poison gas from directly entering from contact gap
The respiratory tract of people causes human injury.But so again bring one it is new the problem of, when people are entered using protective face mask
It is right particularly in the place of cold in use, the aggregation of the liquid such as condensate can be produced in face masks when row expiration or air-breathing
The respirator valve block of face masks, particularly outlet valve, due to the particulate matter such as meeting dust exposure outside outlet valve, produced with internal
Liquid mixing after cause outlet valve opening and closing it is impacted, cause poor sealing to be revealed, influence the gas defence effect of protective face mask.Seriously
When mask bottom can also form ponding and be inhaled by the user in mouth, influence the normal use of protective face mask.
The content of the invention
It is an object of the present invention to it is directed to above-mentioned the deficiencies in the prior art, there is provided a kind of positioned at protective face mask work shape
The extreme lower position of state is provided with draining valve, and its discharge structure is normally open, directly can be exported when there is liquid accumulation outside mask
Portion；When exhaling, portion gas can form to wash away by draining space ensures the clean and tidy of water trap, and draining valve is flowed through in air-breathing
Air-flow during piece gap produces bernoulli effect, enables the protective face mask with draining valve of draining valve quick closedown.
The present invention is to realize above-mentioned purpose by following technical solution：
The protective face mask with draining valve is made up of outer cover plate, mask body, filter, inlet valve, outlet valve and draining valve,
It is characterized in that：Inlet valve is installed before mask body, filter is installed before inlet valve, enclosing cover is installed before filter
Plate；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, which makes, central through hole, outside
Surface, which makes, fixed card slot；The upper end of drain plug, which makes, upper cone, and lower end, which makes, lower cone；Draining valve body passes through solid
Determine the bottom that neck is installed on mask body, drain plug is inserted into the central through hole of draining valve body, and drain plug leads to center
There is gap between hole, 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, which makes, the uniform axle discharge orifice of a circle, the bottom system of central through hole
It is made horn mouth.
Being made in the lower cone of described drain plug has internal taper hole.
Described draining valve is arranged according to the space of protective face mask, positioned at the extreme lower position of protective face mask working condition, row
The discharge structure of water valve is arranged to normally open.
Described draining valve body is made up according to use condition difference of flexible plastic or rigid plastics, when using flexible plastic
When being made, draining valve body can directly with mask body one-shot forming.
The present invention has following beneficial effect compared with prior art：
The protective face mask with draining valve is provided with draining valve in the extreme lower position positioned at protective face mask working condition, anti-
Mask exterior can be exhausted directly to during water aggregation by exhaling by having in face shield；And portion gas can be empty by draining when exhaling
Gap, which forms to wash away, ensures the clean and tidy of water trap, and air-flow when draining valve piece gap is flowed through in air-breathing produces bernoulli effect, makes
Draining valve being capable of quick closedown.Solve and used under existing protective face mask low temperature, particularly in the place of cold in use, mask
Interior condensate impacts to the respirator valve blocks of face masks, the opening and closing of particularly outlet valve, causes poor sealing to be revealed,
The problem of influenceing protective face mask gas defence effect.

Embodiment：
The protective face mask with draining valve is by outer cover plate 1, mask body 2, filter 3, inlet valve 4, outlet valve 5 and draining valve
6 are formed, it is characterised in that：Inlet valve 4 is installed before mask body 2, filter 3 is installed before inlet valve 4, before filter 3
Face is provided with outer cover plate 1；The bottom of mask body 2 is provided with outlet valve 4；The bottom of mask body 2 is provided with draining valve 6.
Described draining valve 6 is made up of draining valve body 6-1 and drain plug 6-2, and draining valve body 6-1 center is made in having
Heart through hole, outer surface, which makes, fixed card slot 6-8；Drain plug 6-2 upper end, which makes, upper cone 6-4, and lower end is made under having
Cone 6-5；Draining valve body 6-1 is installed on the bottom of mask body 2 by fixed card slot 6-8, and drain plug 6-2 is inserted into draining valve
In body 6-1 central through hole, there is gap between drain plug 6-2 and central through hole, drain plug 6-2 by upper cone 6-4 and
Lower cone 6-5 is movably fixed on draining valve body 6-1.
The top of described draining valve body 6-1 central through hole, which makes, the uniform axle discharge orifice 6-3 of a circle, central through hole
Bottom is fabricated to horn mouth 6-7.
Being made in described drain plug 6-2 lower cone 6-5 has internal taper hole 6-6.
Described draining valve 6 is arranged according to the space of protective face mask, positioned at the extreme lower position of protective face mask working condition, row
The discharge structure of water valve 6 is arranged to normally open.
Described draining valve body 6-1 is made up according to use condition difference of flexible plastic or rigid plastics, when using soft
When plastics are made, draining valve body 6-1 can directly with the one-shot forming of mask body 2.
The draining valve 6 of the protective face mask with draining valve is arranged according to the space of protective face mask, can be set to different close
Shape and structure are sealed, the extreme lower position of mask working condition is mounted on, is easy to draining thorough；The draining knot of its draining valve 6
Structure is arranged to normally open, and mask exterior can be exhausted directly to exhaled gas when there is liquid accumulation.The protection with draining valve
The draining valve course of work of mask is, when exhaling, drain plug 6-2 and draining valve that the water of face masks passes through draining valve 6
Gap between body 6-1 central through holes is as expiration is by the much smoother discharge of water, and the gas breathed out shape in drainage gap
Into the cleaning for washing away guarantee draining valve.In air-breathing, drain plug 6-2 is in the presence of pressure of inspiration(Pi), by flowing through draining valve
Bernoulli effect is produced during core 6-2 and draining valve body 6-1 draining gap, drain plug 6-2 is quickly withdrawn, and pass through draining
The horn mouth 6-7 of lower cone 6-5 and draining valve body the 6-1 bottom of valve element 6-2 bottoms cooperation, can quick closedown drain plug 6-
Drainage gap between 2 and draining valve body 6-1 central through holes, makes it gas-insulated with outside, ensures sealing.
The discharge structure of the protective face mask with draining valve forms porous shaft streaming structure, draining valve body 6- using axle discharge orifice
1 and drain plug 6-2 sealing structure is globoidal structure, and washing away for water can keep valve body and base contacts portion in use
The cleaning of position, the reliability for keeping draining valve to use, this small size special type valve body can effectively avoid plane in breathing mask
The influence of sealing difference caused by structure.
