Description
Technical field
The utility model relates to a kind of bowl cover, relates in particular to a kind of bowl cover manual, the automatic air pressure bascule that has concurrently.
Background technology
Drinking glasses or thermos cup that tradition is used, fill hot water after owing to expand with heat and contract with cold, when the water in the cup is colder, contraction of gas, the air pressure of cup the inside promptly produces negative pressure less than the atmospheric pressure of cup outside, bowl cover is just twisted not open; The bowl cover that has some to have hand push button on the market recently, though can eliminate the phenomenon that bowl cover is twisted not open, owing to structural reason, during cleaning, bowl cover is intake easily, brings inconvenience for people's use.
Technical scheme
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of phenomenon that both can solve cup the inside generation negative pressure and bowl cover is twisted not open is provided, and can guarantee the impermeable bowl cover of bowl cover again.
The technical scheme that its technical problem that solves the utility model adopts is: structurally comprise enclosing cover, inner cap, in the inboard of inner cap one sealing ring is set, crown center at enclosing cover is provided with a circular hole, crown center at inner cap is provided with a cylinder groove, the circular hole that covers outward with in the groove that covers corresponding, be symmetrical arranged two air inlet/outlets and an autobalance air valve in the bottom of cylinder groove, one guide collar and hand push button assembly are set in cylinder groove, the hand push button assembly slides along guide collar, the hand push button assembly is by last button, knob down and back-moving spring are formed, one boss is set in the middle of the bottom of knob down, back-moving spring is enclosed within the boss outside, in the middle of the boss small sircle hole is set, the top of autobalance air valve is stretched in this small sircle hole; Junction at enclosing cover and last button is provided with a waterproof apron.Its operation principle is: under the normal condition, under the effect of back-moving spring elastic force, waterproof apron is compressed, form sealing in the lid, after loading onto the hot drink product in the cup, because the effect of autobalance air valve makes cup air pressure interior and bowl cover basic identical, after the drink cooling, form negative pressure with bowl cover in the cup, at this moment bowl cover is twisted not open, and as long as one press hand push button gently, last button breaks away from waterproof apron, air enters in the lid by the periphery of last button and knob down, enter in the cup by aperture, will eliminate with the negative pressure of bowl cover in the cup, bowl cover just can have been turned on.
Realization the utility model had both solved the phenomenon that produces negative pressure inside the cup and bowl cover is twisted not open, and again because waterproof apron is set, guaranteed that bowl cover does not seep water when cleaning, and easy to use, had satisfied consumers in general's demand.
