Abstract
A kind of ventilative respirator, including mask body, ear-hang, it is characterised in that also including the ventilating frame on mask body, ventail, air-vent.The present invention can effectively reduce moisture inside mouth mask, it is also possible that the carbon dioxide of exhalation is smoothly discharged, so as to reach that expiration is smooth.
Description
Technical field
The present invention relates to a kind of life mouth mask, more particularly to a kind of novel ventilated mouth mask.
Technical background
Mouth mask is a kind of living-hygienic articles for use, refer generally to be worn over nose and mouth be used for filter entrance mouth and nose air, with up to
Gas, smell, the spittle to blocking harmful pass in and out the apparatus of wearer's mouth and nose, are made with gauze or paper etc..Mouth mask is to entering lung
The air in portion has certain filtration, when respiratory infectious disease is popular, in the environment of the pollutions such as dust during operation, wears mouth
Cover has extraordinary effect.Particularly haze weight city, mouth mask into know clearly people trip must band article, wearing
Although air filtering can be crossed during mouth mask, also breathing is had some setbacks, when particularly expiration, because the gas of exhalation carries two
Carbonoxide and moisture also have hot gas, and it is difficult discharge that the hot gas of exhalation flows in cover, into the hotbed of bacterium, hot gas and moisture
Again can be vexed on the face so that face is uncomfortable, it is also possible to make facial breed bacteria.
The content of the invention
In view of this, the present invention proposes a kind of ventilative respirator, including mask body, ear-hang, it is characterised in that also including face
Ventilating frame in cover main body, is provided with air-vent on ventilating frame, saturating provided with what can only be opened laterally on the outside of air-vent
Gas piece.
Further, grid is provided with the air-vent, can prevent ventail from entering air-vent.
The present invention can effectively reduce moisture inside mouth mask, it is also possible that the carbon dioxide of exhalation is smoothly discharged, so that
Reach that expiration is smooth.
During using ventilative respirator of the invention, ventail is fitted with air-vent when air-breathing, so as to reach filtering
Effect；Ventail is separated with air-vent when exhaling so that the gas of exhalation easily discharges mouth mask.
Brief description of the drawings
In order to illustrate more clearly of technical scheme, letter will be made to the required accompanying drawing used in embodiment below
Singly introduce, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for the common skill in this area
For art personnel, on the premise of not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
The ventilative respirator that Fig. 1 provides for first embodiment of the invention；
The profile for the ventilative respirator that Fig. 2 provides for first embodiment of the invention.
Embodiment
Further to illustrate that the present invention is to realize technological means and effect that predetermined goal of the invention is taken, below in conjunction with
Accompanying drawing and preferred embodiment, to embodiment, structure, feature and its effect according to the present invention, are described in detail as after.
It refer to Fig. 1, the ventilative respirator that first embodiment of the invention is provided, including mask body 1, ear-hang 2, it is characterised in that
Also include the ventilating frame 3 on mask body, air-vent 5 is provided with ventilating frame 3（Dotted line show air-vent in figure）,
The outside of air-vent 5 is provided with the ventail 4 that can only open laterally（Shown in solid in figure is ventail）.
Fig. 2 is refer to, ventilating frame 3 is that PP expects lattice structure, can play a part of protection and fixed ventilation piece 4 well, thoroughly
The top of gas piece 4 is connected with ventilating frame 3, bottom and surrounding be without any link, and ventail 4 diameter than air-vent 5
Diameter it is big, and grid is provided with air-vent 5, due to that can be fitted when gravity factor ventail 4 is flat with air-vent.
When air-breathing, the external pressure of air-vent 5 is bigger than air pressure inside, and because the diameter of ventail 4 is than air-vent 5
Diameter it is big, and ventail 4 is that also have to be provided with grid at the outside of air-vent 5, air-vent 5, so ventail 5 can be tight
Tight fits with air-vent 5, and can the effective particulate pollutant crossed in air filtering.
When exhaling, the air pressure inside of air-vent 5 is bigger than external pressure, and ventail 4 is in the outside of air-vent 5,
Separated so ventail 4 is easy for being blown open by air pressure with air-vent, air just is easy to out, so that it is smooth to allow for expiration
Not by resistance.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention, though
So the present invention is disclosed as above with preferred embodiment, but is not limited to the present invention, any those skilled in the art, not
Depart from the range of technical solution of the present invention, when the technology contents using the disclosure above make a little change or are modified to equivalent change
The equivalent embodiment of change, as long as being that, without departing from technical solution of the present invention content, the technical spirit according to the present invention is implemented to more than
Any simple modification, equivalent variations and modification that example is made, in the range of still falling within technical solution of the present invention.
