Description

Cup cover

Technical Field

The utility model relates to a drinking cup field especially relates to a drinking cup bowl cover.

Background

Drinking water is a thing that people need to do every day, and drinking more water is beneficial to health. However, people use the glass cup to pour hot water and cover the cup cover, and after the water temperature drops, the cup cover is often not easy to open due to the overlarge pressure difference between the inside and the outside of the cup. Especially in winter, after the glass is poured with hot water and covered with the cup cover for a period of time, the cup cover is not easy to unscrew due to the reduction of air pressure caused by air cooling, and even the glass is cracked, so that women or young and old people with less strength can open the glass with help.

SUMMERY OF THE UTILITY MODEL

The purpose of the invention is as follows: the utility model provides a cup cover, which solves the problem that the cup cover is not easy to open after the temperature of the poured hot water drops.

The technical scheme is as follows: the utility model discloses a cup cover, include the lid and locate set up the gas pocket that can balance the inside and outside atmospheric pressure of cup on the lid, be equipped with on the gas pocket rather than shape cooperation and can close or open the automatic re-setting switch of gas pocket.

The automatic reset switch comprises a sliding block matched with the air hole in a shape, and a spring, wherein one end of the spring is connected with the sliding block, the other end of the spring is connected with the cover body, and the spring can reset the sliding block to close the air hole when the sliding block opens the air hole.

For realizing the relative motion of slider and bowl cover and opening or close the gas pocket, the U type groove that matches with lid thickness is seted up to one side that the slider connects the spring, the lid has been seted up towards one side of slider the spring can penetrate and rather than end-to-end connection's hole, just the spring can contract or open in the hole, wherein, the lid can the relative slider of U type inslot slides.

For better fixed spring, the slider is violently equipped with the cylinder on one side of connecting the spring, the cylinder is located in the recess, the spring housing is located on the cylinder.

In some embodiments, one end of the slider is rotatably connected with the cover body, and the slider can rotate around the connecting point and open or close the air hole.

In order to facilitate sliding the sliding block by hand, a bulge is arranged above the sliding block.

In order to ensure that the air tightness of the water cup is good and the water cup does not leak when inverted, the inner edge of the air hole which is contacted with or disconnected from the sliding block is provided with a rubber ring which can be sealed.

Has the advantages that: the utility model discloses simple structure, effectual solved the difficult problem of opening of bowl cover behind the hot water cooling of drinking cup, and it is effectual to keep warm, does not leak water.

Detailed Description

Referring to fig. 1 to 3, an embodiment of the present invention provides a cup cover, which includes a cover body 1 and an air hole 2 disposed on the cover body 1 for balancing air pressure inside and outside the cup, wherein the air hole 2 is provided with an automatic reset switch which is matched with the air hole and can close or open the air hole.

The automatic reset switch comprises a sliding block 3 matched with the air hole 2 in a shape, a spring 4 with one end connected with the sliding block 3 and the other end connected with the cover body 1, the spring 4 can reset the sliding block 3 to close the air hole when the sliding block opens the air hole 2, a rubber ring 5 capable of sealing is arranged on the inner edge of the air hole 2 contacted with or disconnected from the sliding block 3, and a bulge 6 is arranged above the sliding block 3.

Slider 3 one side of connecting spring 4 is seted up with the U type groove 9 that lid 1 thickness matches, and lid 1 has been seted up towards one side of slider 3 spring 4 can penetrate and rather than end connection's hole 7, and spring 4 can contract or open in hole 7, and wherein, lid 1 can slide relative slider 3 in U type groove 9.

One side of the sliding block 3 connected with the spring 4 is transversely provided with a cylinder 8, the cylinder 8 is arranged in the groove, and the spring 4 is sleeved on the cylinder 8.

In some embodiments, one end of the slider 3 is rotatably connected to the cover 1, and the slider 3 can rotate around the connecting point and open or close the air hole 2.

The utility model discloses a theory of operation: after hot water is poured into the cup, when the water temperature is lowered, the sliding block 3 is slid by hand, the sliding block 3 and the air hole 2 are disconnected, the air pressure inside and outside the cup is balanced, and after the sliding block 3 is released, the sliding block 3 automatically resets under the action of the spring 4, and the cup cover is sealed.
