Detailed Description

In the utility model, based on the conventional straw cup structure, the cup body is made of stainless steel, and the cup mouth is provided with threads; the cup cover 1 and the flip cover 2 are formed by food-grade high-temperature-resistant plastic in an injection molding mode, the flip cover 2 is connected with the rear end of the cup cover 1 through a rotating shaft, and a clamp spring is arranged at the position of a connecting shaft and can automatically flick the cup cover 1; the cup cover 1 is screwed on the cup body 3 through threads, and a circle of sealing ring 12 is arranged on the inner side of the cup cover to seal the cup body; the soft straw is inserted into a top cover hole of the cup cover 1, and the other end of the soft straw reaches the bottom of the cup through the extension rod; the top of the inner side of the flip cover 2 is provided with a vertical downward pressure rod which can press the straw down to lie on the top cover of the cup cover 1, and the straw is compressed into a closed shape to keep the water temperature in the cup body 3; when the flip cover 2 is bounced, the straw rebounds and rises.

The front end of the cup cover 1 is provided with a push rod 4 which can be pressed towards the inner direction of the cup, the front end surface of the push rod 4 is provided with an integrally formed press key 5, and the rod body of the push rod 4 is arranged in a chute structure which is designed in advance in the cup cover 1; a spring 13 is arranged between the pressing key 5 and the side wall of the front end of the cup cover 1; thus, the push key 5 is pressed/released, and the push rod 4 can slide back and forth;

the push rod 4 is provided with a first clamping hook 6 and a second clamping hook 7, the first clamping hook 6 is arranged at the top end of the pressing key 5, the hook faces backwards, the second clamping hook 7 is positioned behind the first clamping hook 5, and the hook faces forwards; a gap is reserved between the first clamping hook 6 and the second clamping hook 7;

2 front end positions of flip cover are equipped with fixed connection's back-off 8, and this back-off 8 structure is as follows:

the reverse buckle 8 is provided with a front limiting plane 9 and a rear limiting plane 10, the two limiting planes are arranged in tandem, and the rear limiting plane 10 is higher than the front limiting plane 9; the front limiting plane 9 is matched with the first hook 6, and the rear limiting plane 10 is matched with the second hook 7;

the reverse buckle 8 can be inserted into the gap between the first hook 5 and the second hook 6.

The cup cover 1 is provided with an air outlet which is communicated up and down, a check valve 11 (commonly called a duckbill valve) is arranged in the air outlet, the cup cover is made of soft silica gel and is of a conventional market structure, the top of the cup cover is provided with an opening end, the middle of the valve body is provided with an openable linear sealable hole end, and the linear sealable hole end can be opened to form an O shape when the linear two ends are extruded and deformed under pressure; the check valve 11 is positioned at the front end of the suction pipe, namely between the suction pipe and the rear end part of the push rod 4, and the push rod 4 does not contact the check valve 11 under the state that the turnover cover 2 is covered on the cup cover 1; as shown in fig. 1.

When the turning cover 2 is covered on the cup cover 1, the first clamping hook 6 is positioned in front of the front limiting plane 9 in the horizontal direction, and the front limiting plane 9 are staggered back and forth in the vertical direction, so that no constraint is formed; the second hook 7 is inserted on the rear limiting plane 10 to form constraint; the flip cover 2 is locked due to the constraint of the second hook 7 and the rear limiting plane 10; as shown in fig. 1.

The pressing key 5 is pressed, the push rod 4 moves backwards, the first stroke is used as the unlocking stroke of the push rod 4, the second clamping hook 7 moves backwards to be separated from the rear limiting plane 10, and constraint is removed; as shown in fig. 2. Meanwhile, as the push rod 4 moves backwards, the first clamping hook 6 moves backwards and falls above the front limiting plane 9, and as the rear limiting plane 10 is higher than the front limiting plane 9, the flip cover 2 can be popped up by a small stroke, so that the front limiting plane 9 is contacted with the lower part of the first clamping hook 6 to form the constraint of the first clamping hook 6 and the front limiting plane 9, and the flip cover cannot be completely popped open; as shown in fig. 3. At this time, due to the small stroke of the flip cover 2, the second hook 7 is located below the rear limiting plane 10; as shown in fig. 3. Meanwhile, the push rod 4 moves backwards, the rear end part of the push rod pushes against and presses the check valve 11, the closed port of the check valve 11 is pressed and opened, and hot air in the cup is sprayed out with part of hot water; as shown in fig. 2 and 3.

When the pressing key 5 is released, the pressing key 5 rebounds to return to the original position under the action of the spring 13, the push rod 4 moves forwards to serve as a second stroke in the unlocking stroke of the push rod 4, at the moment, the first clamping hook 6 moves forwards to be separated from the upper part of the front limiting plane 9 to remove the restriction limitation, the second clamping hook 7 moves forwards to be located below the rear limiting plane 10, the restriction limitation is not generated, and the flip cover 2 can be completely bounced open; at the same time, the check valve 11 restores the sealed state; as shown in fig. 4.

Corresponding structural oblique angles can be directly arranged on the upper end surface of the second clamping hook 7 and the lower end surface of the rear limiting plane 10, so that the second clamping hook 7 can slide into the position below the rear limiting plane 10 when moving forwards, as shown in fig. 4.

The sealing ring 12 is arranged at the joint of the cup cover and the cup body, the sealing ring 12 and the check valve 11 are made of soft silica gel and are connected together to form an integral body, as shown in fig. 5. Thus, the sealing ring 12 and the check valve 11 are integrally formed, and can be formed by only one set of die, so that the production cost is reduced.

The utility model discloses during the use, when want to unblock flip and use the straw to drink water, promote the push rod, the push rod moves to the cup internal direction, in the first section stroke, the push rod extrudes the check valve in advance, make the airtight hole end of check valve extrude the deformation, the in-line shape of airtight hole end can open and be O-shaped, even the venthole is the open mode, make the hot air of internal inflation of cup drive some hot water and discharge from the venthole, release cup internal pressure, at this moment because the push rod has not made pothook and hasp (namely formed pothook and hasp structure by first pothook and second pothook and preceding spacing plane and back spacing plane combination) stagger completely, flip still is in the state of closing on the bowl cover, when hot air and hot water discharge venthole, there is flip to block, can not cause the scald to the user; then the push rod is continuously moved (namely, the external force is released, and the spring rebounds to push the push rod to move), the clamping hook moves along with the push rod and is separated from the locking position of the turnover cover, and the turnover cover can be opened after being unlocked; at the moment, because the air outlet is opened before, the hot air pressure is released, water can not be sprayed in the suction pipe any more, and the risk of scalding a user is solved. The flip cover is closed, the push rod returns, the check valve returns, the air outlet is sealed, hot air is prevented from being emitted, and the heat preservation effect is achieved.

The utility model discloses the advantage lies in that simple structure is ingenious, and convenient to use is swift, and one-hand one-step operation just can accomplish uncapping and gassing operation, can not spout hot water in guaranteeing the straw, and is with low costs, safe and reliable.
