Embodiment of the disclosure is included in the triangle outlet valve used on mask.The triangle of the valve can allow the area of increase to flow through the valve for air, and the comfort level of the breathing of user is improved by the valve.The valve may include the lid that base is attached to by the buckle at three angles of the valve, wherein, along the space of the side of valve can be open between buckle, it is allowed to air flow.The area of the increase of valve is flowed through for air can reduce the resistance of the expiration to user, increase the comfort level of the breathing of the user.Extraly, valve may include transparent lid, and it can allow the motion for observing the valve.The transparent lid may also allow for the customizability of the color of the element of valve or valve, it is allowed to the aesthetics of mask（ascetic）Improve.
Referring now to Fig. 1-2, the exemplary embodiment of the triangle valve used on mask is described.Valve 100 could attach to the surface of mask and allow the breath of the exhalation of user to leave the mask.Pressure change in the mask can open and close the valve.
Valve 100 may include lid 102 and base 104.Valve 100 may include triangle, with three sides and three angles.Lid 102 can pass through the buckle 106 on lid 102 and the buckle on base 104 116（Figure 3 illustrates）It is attached to base 104.Buckle 106 can be located at three angles of valve 100.Between side of the buckle 106 along valve 100, the opening 105 between lid 102 and base 104 can be open so that the air through base 104 can leave opening 105.In certain embodiments, lid 102 may include the spine on the surface of lid 102 or other decoration elements.In certain embodiments, lid 102 may also include mark or manufacturer's title.
Fig. 3 is shown in the exploded view of the valve 100 described in Fig. 1 and Fig. 2.The base 104 of valve 100 may include air vent 110, it is allowed to which air flows through base 104 by center.Air vent 110 may include round-shaped.Valve 100 may also include one or more valve blocks 120, wherein, valve block 120 may also include matched with the size and dimension of air vent 110 round-shaped.Valve block 120 can be held in place between lid 102 and base 104.Valve block 120 can be in the upper seal of air vent 110, and can respond the pressure change caused by the breathing by user in valve 100 come closure or openness.For example, when user exhales, valve block 120 can be promoted by the normal pressure in the mask and opened, and the air breathed out can pass through the air vent 110 in valve 100（And the opening 105 shown in fig. 1 and 2）Leave the mask.Similarly, in user's air-breathing, the negative pressure in the mask can pull valve block 120 to be closed in the top of air vent 110, seal air vent 110 and prevent extraneous air from entering the mask by air vent 110.
The structure of buckle 106 and 116 can be seen in figure 3, and the buckle 106 of its middle cover 102 can be caught in place against the buckle 116 of base 104, keep lid 102 in place on base 104.In certain embodiments, valve 100 may include the wall 112 around the part of valve 100（Or shield）, when valve block 120 is opened by the expiration of user, it is operable to prevent condensate from entering air vent 110.
The triangle of valve 100 can allow bigger open area to be moved out for air from air vent 110 and valve block 120.Extraly, the open area of the increase along the side of the valve 100 can be allowed using three buckles 106 at the angle of valve 100（The valve is left for air）.Referring now to Fig. 4 A-4B, it illustrates the comparison between valve shape.This compares three kinds of different shapes that air vent 110 is surrounded in display（As above it is illustrated）.The shape can be circle 402, square 404 and triangle 406.These shapes all are installed to be compared around the air vent 110 of identical size.Illustrated in figure 4b with strip around each shape（Periphery）And thus illustrate the maximum possible area that air flows out valve that is used for of this shape.Circle 402 and square 404 has the peripheral length for being shorter than triangular shaped 406.Therefore, triangular shaped 406 have the maximum possible area for being used for air outflow valve.The shape of triangle valve and effective area for air flow can influence the pressure through the valve so that user is easier to gas breathing out the valve.
Fig. 5-10 illustrates each view of the above-described valve 100 assembled.Fig. 5 illustrates the top view of valve 100.Fig. 6 illustrates the upward view of valve 100.Fig. 7 illustrates the front view of valve 100.Fig. 8 illustrates the rearview of valve 100.Fig. 9 illustrates the first side view of valve 100.Figure 10 illustrates the second side view of valve 100.
Another embodiment of Figure 11 diagram triangles valve 200.In certain embodiments, the element of valve 200 can be similar to the element of above-described valve 100.In the embodiment in figure 11, valve 200 may include at least partly transparent lid 202.The transparency of lid 202 can allow the valve block 220 and/or other inner members for seeing valve 200.Transparency cover 202 can allow the motion that valve block 220 is seen by lid 202, while still protecting the inner member of valve 200.If the breathing of the user can be monitored by other people（For example under medical environment）, this can be useful.Extraly, transparency cover 202 can provide customization and aesthetic benefit, and its middle valve plate 220 may include the various colors that can be observed by transparency cover 202.
Valve 200 may include it is triangular shaped, with three sides and three angles.Lid 202 can be attached to the base 204 of valve 200 by the buckle 216 on the buckle 206 and base 204 on lid 202.Buckle 206 can be located at three angles of valve 200.Along at the side of valve 200 between buckle 206, the opening 205 between lid 202 and base 204 can be open so that the air through base 204 can leave opening 205.In certain embodiments, lid 202 may include the spine on the surface of lid 202 or other decoration elements.In certain embodiments, lid 202 may also include mark or manufacturer's title.
Figure 12 is shown in the exploded view of the valve 200 described in Figure 11.The base 204 of valve 200 may include air vent 210, it is allowed to which air flows through base 204 by center.Air vent 210 may include round-shaped.Valve 200 may also include one or more valve blocks 220, and its middle valve plate 220 may also include matched with the size and dimension of air vent 210 round-shaped.Valve block 220 can be held in place between lid 202 and base 204.Valve block 220 can be in the upper seal of air vent 210, and can respond the unlatching of the pressure change as caused by the breathing of user in valve 200 and close.For example, when user exhales, valve block 220 can be promoted by the normal pressure in the mask and opened, and the air breathed out can pass through the air vent 210 in valve 200（And by figure 11 illustrates opening 205）Leave the mask.Similarly, in user's air-breathing, the negative pressure in the mask can pull valve block 220 to be closed in the top of air vent 210, seal air vent 210 and prevent extraneous air from entering the mask by air vent 210.
The structure of buckle 206 and 216 can be seen in Figure 11-12, and the buckle 206 of its middle cover 202 can click into place against the buckle 216 of base 204, keep lid 202 in place on base 204.In certain embodiments, valve 200 may include the wall 212 around the part of valve 200（Or shield）, when valve block 220 is unlocked by the expiration of user, it is operable to prevent condensate from entering air vent 210.
Each view of the valve 200 that assembles of Figure 13-18 diagrams with above-described transparency cover 202.Figure 13 illustrates the top view of valve 200.Figure 14 illustrates the upward view of valve 200.Figure 15 illustrates the front view of valve 200.Figure 16 illustrates the rearview of valve 200.Figure 17 illustrates the first side view of valve 200.Figure 18 illustrates the second side view of valve 200.
Figure 19 A-19B diagrams are arranged on the valve 100 of Fig. 1-10 on mask 500.Outlet valve 100 may be mounted to that on the arbitrary portion of mask 500, and can be arranged to and will not hinder the comfort level of user when mask 500 are dressed.The base 104 of valve 100 could attach on the material of mask 500.
