Abstract
The utility model relates to a thermal cup with an easy-to-open cup cover, which is composed of a cup body, a cup cover, and a balance valve arranged in the center of the cup cover. The balanced valve comprises a valve body, a valve, and a valve cover; the upper and the lower ends of the valve body are provided with flangings which are clamped on the upper and the lower face of the cup cover, and a hole is arranged in the center of a base plate of the valve body; a valve lever is arranged in the hole in the center of the base plate, and ventilating holes are arranged on the base plate. After the cup cover is fastened down, thermal insulation conditions in the cup is constantly maintained; after the water temperature is lowered in the cup, the cup cover can be easily opened.
Description
The utility model relates to a kind of thermos cup of easy unlatching bowl cover, belongs to drinking instrument.
What existing thermos cup was used is totally enclosed bowl cover, and when in the cup during splendid attire hot water, people get used to bowl cover screwed makes its airtight insulation.Its weak point is: after treating that water temperature reduces, cup internal cause liquids and gases shrink and negative pressure occurs, and bowl cover is held and is difficult to even can't opens.
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and thermos cup that a kind of easy unlatching bowl cover is provided.
The purpose of this utility model can reach by following measure: the utility model is made of cup, bowl cover and the balanced valve that is loaded on bowl cover central authorities, balanced valve comprises valve body, valve and valve gap, the valve body upper and lower side has flange to be installed on the bowl cover top and bottom, valve body base plate central authorities are porose, valve lever is packed in the base plate medium pore, and base plate has passage.
There is raised line valve gap top board bottom surface.
There is projection in the bonnet lower outside.
The drawing of accompanying drawing is described as follows:
Fig. 1 always schemes for broken section of the present utility model
Fig. 2 is the enlarged drawing of facing of valve gap;
Fig. 3 is the vertical view of Fig. 2;
Fig. 4 is the A portion enlarged drawing of Fig. 1.
Below in conjunction with embodiment and accompanying drawing the utility model is done further to comment:
Fig. 1-Fig. 4 represents general structure of the present utility model.Be placed on the central authorities of the bowl cover 2 on the cup 1, balanced valve is housed, valve body 3 upper and lower sides of balanced valve have flange, for the usefulness that is installed on the bowl cover.Valve body base plate 4 central authorities are porose, the usefulness that the valve lever 6 of confession valve 5 is packed into.The valve body base plate also has passage 7.There is raised line 8 valve gap top board bottom surface, to erect the valve gap top board, makes the air gap that leaves ventilation between top board and the bowl cover.There is projection 9 in the bonnet lower outside, tightly lives valve gap in order to projection peaks at circle in the valve body, simultaneously, also allows the air gap that left gas in the valve gap outside and the valve body between the circle.
During use, pour into boiling water or hot water, screw bowl cover, the cup internal pressure holds out against valve to guarantee that the interior sealing of cup is incubated and water in the cup is not excessive slightly greatly than atmospheric pressure.After treating that the water in the cup temperature drop is low, negative pressure is lower than valve insertion pressure (equaling atmospheric pressure) in the cup, and with the downward breakdown of valve, to reach the pressure balance of valve upper and lower cavity, promptly the cup inner chamber reaches atmospheric pressure, and like this, bowl cover just is easy to outward winding.
The utility model contrast prior art has following advantage:
After covering tightly bowl cover, heat-retaining condition remains unchanged in the cup, after the water in the cup temperature drop is low, is easy to open cup cover.
