Description

Water cup with pressure relief function

Technical Field

The utility model belongs to the technical field of the drinking cup, especially, relate to a drinking cup with pressure release function.

Background

When the existing water cup is used for containing hot water or carbonated beverages, the pressure in the cup is high, the cup cover is easily squeezed by air pressure to cause water leakage, particularly, when the cup is shaken, the pressure can be instantly increased, the cup cover can be exploded by impact, and high danger is realized.

Disclosure of Invention

The utility model aims at providing a drinking cup with pressure release function can real-time pressure release, makes the pressure in the cup keep at safe level, and the security is high.

In order to achieve the above purpose, the utility model adopts the following technical scheme.

The cup with the pressure relief function comprises a cup cover assembly covering the opening of a cup body, wherein a pressure relief channel communicated with the inside and the outside of the cup is formed in the cup cover assembly, and a pressure relief device is arranged at one end of the pressure relief channel.

Above-mentioned scheme through set up pressure release passageway and pressure relief device on the bowl cover subassembly, can realize real-time pressure release, makes the pressure in the cup keep at safe level, and the security is high.

The cup cover assembly comprises an upper cover, the pressure relief channel is arranged in the upper cover, an air inlet of the pressure relief channel is arranged on the bottom surface of the upper cover, an air outlet of the pressure relief channel is arranged on the side wall of the upper cover, and the pressure relief device is arranged on the air inlet.

Pressure relief device includes waterproof ventilated membrane and the middle mounting that link up, the upper end of air inlet is equipped with a plurality of pressure release holes, mounting detachably sets up in the air inlet, will waterproof ventilated membrane sticiss in the below in pressure release hole.

The cup cover assembly further comprises a lower cover which is made of plastic materials and has an upper end opening screwed on the opening of the cup body, the upper cover is screwed on the lower cover, a plurality of water outlet holes are formed in the bottom surface of the lower end of the lower cover in a penetrating mode, and the upper end of the lower cover is higher than the opening of the cup body.

Compared with the prior art, the beneficial effects of the utility model are that: through set up pressure release channel and pressure relief device on the bowl cover subassembly, can realize real-time pressure release, make the pressure in the cup keep at safe level, the security is high. Pressure relief device can make pressure relief device keep normally open state to carry out real-time pressure release through setting up waterproof ventilated membrane on the one hand, and on the other hand can let gas pass through and block that liquid passes through, can prevent that liquid from spilling from the relief valve subassembly, also need not worry when pressure release in-process or drinking cup are emptyd from the problem of leaking from the relief valve subassembly, increases the security.

The further beneficial effects are that: through setting up the spiro union and being higher than the lower cover of rim of a cup in rim of a cup and upper end, the user when drinking water, lip and lower cover contact and not with the contact of cup oral area, because the lower cover of plastic material compares with stainless steel's cup oral area to the sense of touch of lip, and is softer and not ice-cold, and the sense of touch is better, increases and uses experience.

Detailed Description

In order to make the technical solution of the present invention clearer, the following describes the present invention in detail with reference to fig. 1 to 2. It should be understood that the detailed description and specific examples, while indicating the scope of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.

The utility model relates to a drinking cup with pressure release function, including cup 1 and bowl cover subassembly, bowl cover subassembly lid closes and is used for the switching rim of a cup at cup 1's oral area, is equipped with the inside and outside pressure release passageway 21 of intercommunication drinking cup on the bowl cover subassembly, is equipped with pressure relief device in the one end of pressure release passageway 21.

In one embodiment, the cup cover assembly comprises an upper cover 2, wherein the side wall of the upper cover is provided with external threads which are matched and connected with internal threads of the opening part of the water cup, a pressure relief channel 21 is arranged in the upper cover 2, an air inlet of the pressure relief channel is arranged on the bottom surface of the upper cover 2, an air outlet of the pressure relief channel is arranged on the side wall of the upper cover 2, and a pressure relief device is arranged on the air inlet.

Preferably, the pressure relief device comprises a waterproof breathable film 31 and a fixing part 32 which penetrates through the middle of the waterproof breathable film, the upper end of the air inlet is provided with a plurality of pressure relief holes 22, the fixing part 32 is detachably arranged in the air inlet in a clamping or threaded connection mode, and the waterproof breathable film 31 is tightly pressed below the pressure relief holes 22. With this structure, the waterproof breathable film 31 can be easily replaced by detaching the fixing member 32.

A cup cover sealing ring 5 is arranged on the side wall below the upper cover 2, and a seal is formed between the cup cover sealing ring and the mouth of the water cup.

The use principle is as follows: the waterproof breathable film 31 can allow gas to pass through and block liquid from passing through, so that liquid can be prevented from leaking out of the pressure relief channel 21, and the problem of water leakage from the pressure relief channel 21 is avoided in the pressure relief process or when a water cup is toppled. Through setting up waterproof ventilated membrane 31 and pressure release channel 21, pressure relief device is normally open state, and the drinking cup is in the pressure release state in real time, keeps safe pressure level.

In the second embodiment, on the basis of the above-mentioned embodiment, the cup cover assembly further comprises a lower cover 4, the upper end of the lower cover 4 is opened and screwed in the mouth of the cup body 1, a plurality of water outlets are arranged on the bottom surface of the lower end of the lower cover in a penetrating manner, and the upper end of the lower cover 4 is higher than the mouth of the cup body 1.

The upper cover 2 is connected with the lower cover 4 in a threaded manner, and a cup cover sealing ring 5 is arranged on the side wall below the upper cover and forms sealing with the lower cover 4.

A cover sealing ring 6 is arranged on the side wall below the lower cover 4, and a seal is formed between the cover sealing ring and the mouth of the water cup.
