Realize the utility model discloses, owing to set up air supplement unit, make the inside and outside atmospheric pressure balance of cup, overcome thermos cup commonly used and lead to twisting not opening or the difficult phenomenon of unscrewing because of the negative pressure, reach and open the convenience and have good sealing performance again, product fashion is novel, handsome in appearance.
Description
The utility model relates to a kind of insulating utensils, particularly relates to a kind of thermos cup.
At present, the thermos cup that people generally use, its bottle cap mostly are single layer structure, when the splendid attire hot beverage and after tightening bottle cap, because the variation of cup internal and external temperature causes the air pressure imbalance, causes glass interior negative pressure and the phenomenon that causes bowl cover to twist not open or be difficult for turning on, makes troubles to daily life.
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of existing good seal performance is provided and opens conveniently fashionable, handsome in appearance thermos cup.
For achieving the above object, the utility model structurally comprises cup and bowl cover, bowl cover is made up of loam cake, inner cap and enclosing cover, inner cap is provided with making-up air device, making-up air device by the valve valve that is arranged on inner cap central authorities and valve valve two pores under topped form, loam cake communicates with atmosphere through the screw thread discontinuities with cavity in the middle of the inner cap.Its operation principle is: after the splendid attire drink, when cup internal gas pressure during more than or equal to atmospheric pressure, movable valve relies on self elastic force to be close to inner cap, stops cross-ventilation; When the cup internal gas pressure was lower than atmospheric gas pressure, valve opened automatically, air tonifying Qi in pore flows into cup, and behind air pressure balance, the valve valve is replied the state that is adjacent to, and keeps good seal performance.
Realize the utility model, because making-up air device is set, make a glass inside and outside air pressure balance, overcome thermos cup commonly used and caused the phenomenon of twisting not open or being difficult for turning on because of negative pressure, reaching to open to make things convenient for has excellent sealing performance again, and product is fashionable, and is handsome in appearance.
Below in conjunction with accompanying drawing structural principle of the present utility model is described in further detail.
Fig. 1 is a structural principle schematic diagram of the present utility model.
