Description
Technical field
The utility model relates to a kind of water tumbler that can balance pressure in cup, belongs to consumer goods industries.
Background technology
When filling hot water in our water tumbler, the steam having water vapor to be formed in the gas in water tumbler, also has air.Because gas expands with heat and contract with cold, time you pour hot water into, the air inside cup is all awfully hot, waits water cool, will produce negative pressure, thus holds bowl cover and be difficult to not open.When water tumbler is filled with very full, after temperature reduces, steam liquefies, and due to side's little air waterborne, pressure reduces clearly (also the limit can consider, if filled, do not have air, after temperature reduces, steam all liquefies, and is just equivalent to vacuum).In this case, in cup, pressure is less than external atmosphere pressure, and external atmosphere pressure handle cup covers tightly and is pressed on cup, and bowl cover is just difficult to open.
Utility model content
In order to solve the problem, the utility model proposes a kind of water tumbler that can balance pressure in cup, when in cup, pressure reduction is difficult to open bowl cover, intake valve is up mentioned, the air of outside will enter in cup by air admission hole, and after having entered gas, the spring below air inlet post can be returned by appliance for releasing single, and now inside and outside cup pressure consistent, bowl cover is just opened than being easier to.
The utility model solves the technical scheme that its technical problem adopts: a kind of water tumbler that can balance pressure in cup, comprise cup, bowl cover, bowl cover inside groove, inlet valve hole, intake valve, described bowl cover is threaded with cup, bowl cover inside groove is had in bowl cover, bowl cover has inlet valve hole, described intake valve inserts in inlet valve hole, and its bottom enters in bowl cover inside groove; Described intake valve comprises upper cover, air inlet post, air admission hole, mesopore, spring and lower cover, described upper cover is connected in air inlet capital end, air inlet post bottom is connected lower cover, vertical mesopore is provided with in the middle of described air inlet post, the venthole of mesopore is positioned at lower cover center, and air inlet post upper portion side wall has the air admission hole being communicated with mesopore; The diameter of described upper cover and lower cover is all greater than air inlet post, and described spring housing is located on air inlet post, is stuck between lower cover and bowl cover.
Described spring is extension spring.
The stroke of described spring is not less than the distance of air admission hole distance upper cover.
The beneficial effects of the utility model are: a kind of water tumbler that can balance pressure in cup, when in cup, pressure reduction is difficult to open bowl cover, intake valve is up mentioned, the air of outside will enter in cup by air admission hole, after having entered gas, spring below air inlet post can be returned by appliance for releasing single, and now inside and outside cup pressure consistent, bowl cover is just opened than being easier to.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is a kind of structural representation that can balance the water tumbler of pressure in cup.
In figure, 1. cup, 2. bowl cover, 21. bowl cover inside grooves, 22. inlet valve hole, 3. intake valve, 31. upper covers, 32. air inlet posts, 33. air admission holes, 34. mesopores, 35. springs, 36. lower covers.
Detailed description of the invention
In the drawings, a kind of water tumbler that can balance pressure in cup, comprise cup 1, bowl cover 2, bowl cover inside groove 21, inlet valve hole 22, intake valve 3, described bowl cover 2 is threaded with cup 1, bowl cover inside groove 21 is had in bowl cover 2, bowl cover 2 has inlet valve hole 22, described intake valve 3 inserts in inlet valve hole 22, and its bottom enters in bowl cover inside groove 21; Described intake valve 3 comprises upper cover 31, air inlet post 32, air admission hole 33, mesopore 34, spring 35 and lower cover 36, described upper cover 31 is connected in air inlet post 32 top, air inlet post 32 bottom is connected lower cover 36, vertical mesopore 34 is provided with in the middle of described air inlet post 32, the venthole of mesopore 34 is positioned at lower cover 36 center, and air inlet post 32 upper portion side wall has the air admission hole 33 being communicated with mesopore 34; The diameter of described upper cover 31 and lower cover 36 is all greater than air inlet post 32, and described spring 35 is sheathed on air inlet post 32, is stuck between lower cover 36 and bowl cover 2.
Described spring 35 is extension spring.
The stroke of described spring 35 is not less than the distance of air admission hole 33 apart from upper cover 31.
When in cup, pressure reduction is difficult to open bowl cover 2, intake valve 3 is up mentioned, and the air of outside will enter in cup by air admission hole 33, after having entered gas, spring 35 below air inlet post 32 can be returned by appliance for releasing single, and now inside and outside cup pressure consistent, bowl cover 2 is just opened than being easier to.
