Abstract
The utility model discloses a kind of breathing mask thin film outlet valve.Including substrate diaphragm, connecting portion, lower diaphragm and upper diaphragm, four is one-body molded, wherein substrate diaphragm is provided with blow vent one, lower diaphragm is provided with blow vent two, lower diaphragm is connected with substrate diaphragm by connecting portion makes blow vent one and blow vent two connection, and upper diaphragm connects with the edge of lower diaphragm by being connected limit and is installed with ventilation mouth connecting limit.The utility model has the advantage of, when breathing, upper thin slice is full wafer action, does not has the restriction of supporter, and the startup power needed when with lower thin slice Guan Bi or unlatching is the least, and user uses for a long time and is not easily tied.
Description
Technical field
This utility model belongs to outlet valve field, more specifically, particularly relates to a kind of breathing mask thin film outlet valve.
Background technology
Existing outlet valve is typically all and is made up of expiration cover, expiration bottom and expiration film, and expiration film is arranged on expiration
Between cover and expiration bottom, the mid portion of expiration film is connected with expiration bottom, when breathing, and the limit of gas push expiration film
Edge portion is allowed to and exhales bottom closure or openness, and when such outlet valve is breathed, be failure to actuate in position, intermediate portion, only edge
Partial act, is limited by thickness effect and the supporter of expiration film itself, can be relatively elaborate when people breathes, and uses for a long time
Time user the most tired.
Summary of the invention
The purpose of this utility model is the problem in order to solve above-mentioned existence, it is provided that the power needed when can reduce breathing
Degree, simple and practical a kind of breathing mask thin film outlet valve.
This utility model is achieved through the following technical solutions.
This utility model is a kind of breathing mask thin film outlet valve, including substrate diaphragm, connecting portion, lower diaphragm and upper film
Sheet, four is one-body molded, and wherein substrate diaphragm is provided with blow vent one, and lower diaphragm is provided with blow vent two, and lower diaphragm is by even
The portion that connects is connected with substrate diaphragm makes blow vent one and blow vent two connection, and upper diaphragm connects by being connected limit with the edge of lower diaphragm
And it is installed with ventilation mouth connecting limit.
Preferably, described upper diaphragm is identical with the overall dimensions of lower diaphragm, and the height connecting limit is 0.5 ~ 1mm.
Preferably, being provided with sinking portion in the middle of described upper diaphragm, this sinking portion includes sinking to the bottom and sinking to the bottom with upper diaphragm even
The chamfering connect sinks limit, and the overall dimensions wherein sunk to the bottom is identical with blow vent two.
Preferably, the Breadth Maximum of described connecting portion is less than substrate diaphragm and the Breadth Maximum of lower diaphragm.
Preferably, the quantity of described ventilation mouth is one.
The utility model has the advantage of, breathe time, upper thin slice is full wafer action, does not has the restriction of supporter, with
The startup power needed when lower thin slice Guan Bi or unlatching is the least, and user uses for a long time and is not easily tied.
Accompanying drawing explanation
Fig. 1 is the structural representation during unlatching of this utility model ventilation mouth.
Fig. 2 is structural representation during this utility model ventilation mouth Guan Bi.
Fig. 3 is cross section structure schematic diagram of the present utility model.
Fig. 4 is the state reference map that this utility model is arranged on breathing mask.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
As shown in Fig. 1 to Fig. 3, this utility model is a kind of breathing mask thin film outlet valve, including substrate diaphragm 1, even
Connecing portion 2, lower diaphragm 3 and upper diaphragm 4, four is one-body molded, and wherein substrate diaphragm 1 is provided with blow vent one, and lower diaphragm 3 is provided with
Blow vent two, lower diaphragm 3 is connected with substrate diaphragm 1 by connecting portion 2 makes blow vent one and blow vent two connection, described connecting portion
The Breadth Maximum of 2 is less than substrate diaphragm 1 and the Breadth Maximum of lower diaphragm 3, in order to be conveniently arranged on breathing mask by outlet valve,
Upper diaphragm 4 connects with the edge of lower diaphragm 3 by being connected limit 5 and is installed with ventilation mouth 6 connecting limit 5, and quantity is one.Inhaling
During gas, upper diaphragm 4 is because external atmospheric pressure is more than inner side air pressure, and upper diaphragm 4 can be adjacent to lower diaphragm 3, and ventilation mouth 6 closes, relative,
During expiration, the external atmospheric pressure of upper diaphragm 4 is less than inner side air pressure, and upper diaphragm 4 leaves lower diaphragm 3, and ventilation mouth is opened.
In the present embodiment, described upper diaphragm 4 is identical with the overall dimensions of lower diaphragm 3, and the height connecting limit 5 is 0.5 ~
1mm, i.e. the distance controlling of upper diaphragm 4 and lower diaphragm 3 is between 0.5 ~ 1mm, can ensure that when by smaller power air-breathing
Diaphragm 4 can be adjacent to lower diaphragm 3 well makes ventilation mouth close.
As it is shown on figure 3, as improving further, be provided with sinking portion 7 in the middle of described upper diaphragm 4, this sinking portion 7 includes sinking to the bottom
71 and sink limit 72 by sinking to the bottom 71 chamferings being connected with upper diaphragm 4, wherein sink to the bottom 71 overall dimensions identical with blow vent two,
During air-breathing, blow vent two can be blocked by sinking portion 7, in order to improve the closure of outlet valve.
Above example is this utility model preferred embodiment, but embodiment of the present utility model is not by above-mentioned reality
Execute the restriction of example, change that other any is made without departing from essence of the present utility model and principle, modify, substitute, combine, all
Within being in like manner included in scope of patent protection of the present utility model.
