Abstract
The utility model discloses a pneumatic valve and have bowl cover of this pneumatic valve has last cavity and lower cavity, goes up the cavity and has the baffle between the cavity down, and it has the through -hole to open on the baffle, and the pneumatic valve lid that roughly is down the U -shaped is arranged in the cavity, the pneumatic valve cover with last cavity in intermural gapped, the pneumatic valve covers keeps away from the baffle to and has elasticity return device between the baffle, the pneumatic valve is covered has protruding axle, and protruding axle passes and be gapped between the through -hole from the through -hole, protruding axle lower extreme is connected with the pneumatic valve lower cover, and the pneumatic valve lower cover is arranged in lower cavity and keeps away from the baffle, and protruding epaxial still cover has the sealing washer, and the sealing washer lies in between baffle and the pneumatic valve lower cover, the pneumatic valve lower cover is internal intermural gapped with the cavity of resorption. Press the pneumatic valve lid, the pneumatic valve lid drives protruding axle and the pneumatic valve lower cover moves down, and through -hole, the upper portion air and the lower part circulation of air of baffle are kept away from to the sealing washer. This pneumatic valve and bowl cover can balance the interior and cup external pressure of cup, the light bowl cover of opening.
Description
Technical field
The utility model belongs to daily living article, specifically a kind of air valve and the bowl cover with this air valve.
Background technology
In use, when the fluid temperature in cup is higher, the air pressure in cup is larger than the outer air pressure of cup, and be now malleation in cup, bowl cover is by the outside jack-up of air pressure for existing seal cup; When the fluid temperature in cup is lower, the air pressure in cup lower than the outer air pressure of cup, and becomes negative pressure, and bowl cover is inwardly adsorbed by negative pressure.What therefore no matter formed in cup is malleation or negative pressure, all very easily increases the frictional force of bowl cover and rim of a cup junction, thus allows user be not easy to open bowl cover, bring certain puzzlement to daily life.
Utility model content
The technical problems to be solved in the utility model overcomes the deficiencies in the prior art, provides a kind of air valve and the bowl cover with this air valve, and this air valve when bowl cover is not opened, can make a glass inner air and outer air circulation, eliminate pressure in cup, easily open bowl cover.Another technical problem that will solve of the utility model is to provide a kind of bowl cover with air valve.
For solving the problems of the technologies described above, the utility model provides a kind of air valve, it has upper cavity and lower chamber, dividing plate is had between upper cavity and lower chamber, dividing plate has through hole, is roughly arranged in upper cavity in inverted U-shaped air valve cap, between the inwall of air valve cap and upper cavity, has gap, air valve cap away from dividing plate, and and between dividing plate, there is elastic recovery device; Air valve cap has convex axle, convex axle and air valve cap one-body molded, convex axle from through hole through and and through hole between have gap; Convex axle lower end is connected with air valve lower cover, and air valve lower cover is arranged in lower chamber and away from dividing plate, on convex axle, also cover has sealing ring, and sealing ring, between dividing plate and air valve lower cover, has gap between described air valve lower cover and lower chamber inwall.
When needing to open bowl cover, downward pressing air valve cap, air valve cap moves down together with air valve lower cover with convex axle, sealing ring on convex axle also moves down, sealing ring is away from through hole, cup outer air is entered and cup inner air flow by the gap between air valve cap and upper cavity inwall, through hole, gap between air valve lower cover and lower chamber inwall, balance cup external and internal pressure, thus opens bowl cover; Afterwards, unclamp finger, air valve cap, under the effect of elastic recovery device, moves up, and drives convex axle to move together with air valve lower cover, and also upwards, be against through hole, the upper and lower air of dividing plate no longer circulates sealing ring, plays sealing function synchronously.
Preferably, described elastic recovery device is spring, and spring housing is on convex axle, and upper end is against on air valve cap, and lower end is against on dividing plate.
Preferably, cover under described air valve and have several passages, air can be made to circulate fast.
The utility model also provides a kind of bowl cover with air valve, and described bowl cover is provided with air valve as above.
Accompanying drawing explanation
Fig. 1 is the top view of the utility model bowl cover.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the enlarged drawing in M portion in Fig. 2.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
A kind of air valve 2, as shown in FIG. 1 to 3, be installed on bowl cover 1, there is upper cavity 22 and lower chamber 24, there is dividing plate 28 between upper cavity 22 and lower chamber 24, dividing plate 28 has through hole 23, be roughly arranged in upper cavity 22 in inverted U-shaped air valve cap 21, have gap between the inwall of air valve cap 21 and upper cavity 22, air valve cap 21 is away from dividing plate 28; Air valve cap 21 has convex axle 29, convex axle 29 is one-body molded with air valve cap 21, and convex axle 29 passes from through hole 23 also and between through hole 23 has gap; Convex axle 29 lower end is connected with air valve lower cover 26, and described air valve lower cover 26 top has groove, and convex axle 29 is fixed in groove, and air valve lower cover 26 is arranged in lower chamber 24 and away from dividing plate 28; On convex axle 29, cover has spring 210, and spring 210 upper end is against on air valve cap 21, and lower end is against on dividing plate 28; On convex axle 29, also cover has sealing ring 27, and sealing ring 27 is between dividing plate 28 and air valve lower cover 26; Described air valve lower cover 26 has several passages 25, air can be made to circulate fast, between described air valve lower cover 26 and lower chamber 24 inwall, have gap.
The utility model can also provide a kind of bowl cover 1 with air valve 2, when needing to open bowl cover 1, press the air valve cap 21 of pressure valve 2 downwards, air valve cap 21 moves down together with air valve lower cover 26 with convex axle 29, and the sealing ring 27 on convex axle 29 also moves down, and sealing ring 29 is away from through hole 23, the upper and lower air circulation of dividing plate 28, the inside and outside air circulation of cup, balance cup external and internal pressure, thus open bowl cover 1; Afterwards, unclamp finger, air valve cap 21, under the effect of spring 210, moves up, and drives convex axle 29 to move together with air valve lower cover 26, and also upwards, be against through hole 23 place, the upper and lower air of dividing plate 28 no longer circulates sealing ring 27, plays sealing function synchronously.
The foregoing is only preferred embodiment of the present utility model, not thereby limit scope of patent protection of the present utility model, the utility model can also carry out the improvement of equivalence to the structure of above-mentioned various parts.Therefore the equivalent structure change that all utilizations description of the present utility model and diagramatic content are done, or directly or indirectly apply to other correlative technology fields and be all in like manner all included in the scope that the utility model contains.
