Summary of the invention
The utility model wants the technical solution problem to be, the mouth mask that a kind of simple in structure, good filtration effect, expiration are smooth and easy, be easy to process and be convenient to wide popularization and application is provided.
For solving above technical problem; The technical scheme of the utility model is: a kind of mouth mask that has outlet valve; Comprise three-dimensional cup cover and be arranged on the outlet valve on the said three-dimensional cup cover; Said outlet valve is made up of the wedge shape stria, and said wedge shape stria extends along deviating from the human body face direction, and the end of said wedge shape stria bearing of trend is two is not having external force to abut against thin slice together as the time spent.
Preferably, said outlet valve is located at said three-dimensional cup cover and goes up the end near the human body chin.
Improvement as the utility model; On the edge of said three-dimensional cup cover, be connected with soft sealing ring; Said soft sealing ring comprises first end, circle body that matches with human body face that is connected with three-dimensional cup cover and second end that extends to the human body oral area, offers the breach that cooperates with the bridge of the nose in the position of said second end and nose cooperation.
Further improve as the utility model, be connected with fixed band on the said three-dimensional cup cover, said fixed band comprises head halter and bundle neck band, and face location is the X-shaped chi structure in the human body left and right sides for said head halter and said bundle neck band.
As the utility model improvement further; Be provided with the concave support frame in the said three-dimensional cup cover; Said nonwoven layer comprises preceding nonwoven layer, middle nonwoven layer and back nonwoven layer, and said three-dimensional cup cover comprises superimposed successively preceding nonwoven layer, bracing frame, middle nonwoven layer, filter cotton layer and back nonwoven layer.
Further improve as the utility model, support frame as described above comprises not in same plane and interconnective first ring and second ring, the area that the area that said second ring is surrounded is surrounded less than said first ring again.
Through implement the utility model desirable following beneficial effect:
A kind of mouth mask that has outlet valve; Comprise three-dimensional cup cover and be arranged on the outlet valve on the said three-dimensional cup cover; Said outlet valve is made up of the wedge shape stria; Said wedge shape stria extends along deviating from the human body face direction, and the end of said wedge shape stria bearing of trend is two is not having external force to abut against thin slice together as the time spent.This outlet valve structure can in time be opened when exhaling; Discharge the gas of breathing out swimmingly; Outlet valve can in time cut out when air-breathing; Enter in the mouth mask after letting gas to be filtered filter through the multiple filtration layer, what can under the prerequisite that guarantees the filter effect that mouth mask is good, ensure respiration like this is smooth and easy, has improved the comfort level of wearing.Said outlet valve is located at said three-dimensional cup cover and goes up the end near the human body chin; Such structure makes outlet valve and nostril face; The gas of breathing out can be discharged fast in time, has avoided breath not discharge fully and causes sulks, has improved the comfort level of wearing.
On the edge of said three-dimensional cup cover, be connected with soft sealing ring, said soft sealing ring comprises first end, circle body that matches with human body face that is connected with three-dimensional cup cover and second end that extends to the human body oral area,
Position in said second end and nose cooperation offers the breach that cooperates with the bridge of the nose.This structure has guaranteed that mouth mask and human body face are combined closely when wearing, and enters into the risk in the mouth mask thereby stopped air to be filtered from the slit of mouth mask and human body face, has improved filter effect.
Be connected with fixed band on the said three-dimensional cup cover, said fixed band comprises head halter and bundle neck band, and said head halter and said bundle neck band are the X-shaped chi structure in the human face position, and said X-shaped chi structure is arranged on people's left and right sides face position.This structure makes head halter apply a power obliquely for three-dimensional cup cover, and the bundle neck brings three-dimensional cup cover and applies an oblique power down, thereby makes three-dimensional cup cover under the effect of these two power and human body face can be combined closely.Head is compared with ear with neck can bear bigger pulling force, thereby has guaranteed that comfortable wearing degree is preferably arranged under the prerequisite that the pulling force that satisfies the mouth mask sealing fully requires.
Said three-dimensional cup cover comprises nonwoven layer and the filter course that is superimposed with each other; Be provided with the said nonwoven layer of concave support frame in the said three-dimensional cup cover and comprise preceding nonwoven layer, middle nonwoven layer and back nonwoven layer; Said three-dimensional cup cover comprises superimposed successively preceding nonwoven layer, bracing frame, middle nonwoven layer, filter cotton layer and back nonwoven layer, and support frame as described above comprises not in same plane and interconnective first ring and second ring.The concave support frame can guarantee between three-dimensional glass of inboard of covering and the mouth and nose certain clearance is arranged, thereby can not have influence on daily speech talk, and a plurality of filter courses that are superimposed with each other successively together make that the filter effect of mouth mask is better.The bracing frame that interconnective ring constituted in same plane does not greatly reduce the weight of cup cover under the prerequisite that enough gaps are arranged between inboard that guarantees three-dimensional cup cover and the mouth and nose, makes mouth mask more light and handy, wears more comfortable.The area that said second area that surrounded of ring is surrounded less than said first ring, this support frame structure makes three-dimensional cup form an approximate hemispherical, has increased the filter course area to greatest extent, has guaranteed air-breathing smooth and easyly, has avoided sulks.
