Abstract
The utility model relates to a thermos cup. Principally, a valve body is arranged at the center of a cup cover, and a small hole is arranged on an inner wall of the cup cover. A valve core is also penetrated in the small hole, and a sealing ring, a spring, and a nut screwed on the upper end of valve core are sheathed on the valve core. Thus, the utility model is convenient to be operated, and sealing effect is not influenced.
Description
The utility model relates to a kind of thermos cup.
At present, after common thermos cup is contained hot water, tighten sealing with bowl cover after, treat that the hot water water temperature descends, just produce negative pressure in the cup, cause bowl cover to be difficult for opening by suction, cause trouble.
In view of this, the purpose of this utility model provides a kind of thermos cup with the automatic air pressure balanced valve, and it is to borrow the air pressure balance valve that is arranged on the bowl cover, makes glass internal gas pressure consistent with ambient pressure.
The purpose of this utility model is achieved in that it mainly comprises cup and bowl cover, be provided with a valve body at the center of bowl cover, and offer an aperture on the bowl cover inwall, wear a spool again in this aperture, this valve core upper sleeve is established sealing ring, spring and is screwed in the nut of spool upper end.
Described spring upper and lower end is respectively against nut and above the bowl cover inwall.
Owing to adopt such scheme: easy to operate, do not influence sealing effectiveness again.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 the utility model exemplary embodiments schematic diagram.
Among the figure:
1, cup 2, bowl cover 21, aperture
22, valve body 23, spool 231, sealing ring
232, spring 233, nut 24, valve gap
Present embodiment mainly comprises cup 1 and bowl cover 2, as shown in Figure 1, and wherein:
Cup 1 is the double-layer stainless steel housing, belongs to prior art.
After pouring hot water in the cup 1, screw bowl cover 2, the air pressure (steam) of hot water (boiling water) upwards pushes spool 23, makes sealing ring 231 to below bowl cover 2 inwalls, makes aperture 21 sealings, keeps the interior hot water heat radiation of cup little;
The hot water temperature descends in cup 1, and steam disappears, and produces negative pressure in the cup 1, pulling spool 23 is (compression spring 232) downwards, makes sealing ring 231 throw off bowl cover 2 inwalls, and aperture 21 just can be ventilated, make the inside and outside air pressure balance of cup, bowl cover 2 takes off at an easy rate, reaches easy to use.
Claims (2)
1, a kind of thermos cup with the automatic air pressure balanced valve, comprise cup (1) and bowl cover (2), it is characterized in that: be provided with a valve body (22) at the center of bowl cover (2), and offer an aperture (21) on bowl cover (2) inwall, wear a spool (23) again in this aperture (21), this spool (23) is gone up sheathed sealing ring (231), spring (232) and is screwed in the nut (233) of spool (23) upper end.
2, by the thermos cup of the described band automatic air pressure of claim 1 balanced valve, it is characterized in that: described spring (232) upper and lower end is respectively against nut (233) and bowl cover (2) above the inwall.
