Detailed Description
In the invention, based on the conventional straw cup structure, the cup body is a stainless steel cup body, and the cup opening is a thread; the primary cup cover 1 and the secondary cup cover 2 are formed by injection molding of food-grade high-temperature resistant plastic; the primary cup cover 1 is screwed on the cup body through threads, the cup body is sealed, and the soft suction pipe is inserted into a top cover hole of the primary cup cover 1 until reaching the bottom of the cup; the secondary cup cover 2 is provided with an integrally formed pressing rod, when the secondary cup cover 2 is covered on the primary cup cover 1, the pressing rod can press the suction pipe to lie on the top cover of the primary cup cover 1, and the suction pipe is compressed to be airtight; when the secondary cup cover 2 is opened, the suction pipe contacts and seals and bounces up; one side of the primary cup cover 1 is connected with one side of the secondary cup cover 2 through a rotating shaft, and a spring piece capable of bouncing off the secondary cup cover 2 is arranged on the rotating shaft.
The primary cup cover 1 is provided with an air outlet duct 5 which is vertically communicated; a transverse rectangular empty groove 6 is arranged in the top cover surface of the primary cup cover 1, the opening of the empty groove 6 is positioned on one side opposite to the rotating shaft, the empty groove is communicated with the suction pipe from the side surface of the top cover surface of the primary cup cover 1, and the middle of the empty groove is communicated with the air outlet duct 5 to divide the air outlet duct 5 into an upper duct and a lower duct; the push rod 4 is inserted into the recess 6 and can move back and forth in the recess 6.
A butt joint air outlet hole 7 is arranged on the push rod 4, and the butt joint air outlet hole 7 can butt joint an upper section of the air outlet hole 5 and a lower section of the air outlet hole; when the secondary cup cover 2 is covered and locked on the primary cup cover 1, the push rod 4 is positioned at the outermost end of the empty groove 6 as an initial position, the butt joint air outlet 7 is staggered and sealed with the air outlet duct 5, and the push rod 4 is not extruded to the suction pipe; the stagger distance between the butt joint air outlet hole 7 and the air outlet duct 5 is the stroke of the push rod 4, namely the moving distance required by the push rod 4 from the initial position to the extrusion suction pipe to the closed state.
A silica gel layer area 13 is arranged around the butt joint air outlet holes 7 on the upper surface and the lower surface of the push rod 4, the silica gel layer is slightly higher than the surface of the push rod 4 by 0.1-0.3 mm, a double-material injection molding process and the push rod 4 are integrally formed, and the silica gel layer area 13 covers the position of the air outlet duct 5 when the push rod 4 is located at the initial position and the pressed position. So as to ensure that peripheral gaps of the air outlet duct 5 and the butt joint air outlet holes 7 are sealed in butt joint and non-butt joint states, and no air leakage occurs; meanwhile, the silica gel is soft, and the movement of the push rod 4 is not influenced. As shown in fig. 3.
The cup cover edge of the secondary cup cover 2 is inwards turned over to be protruded to form a clamping groove 8, namely an inverted clamping hook, a clamping hook 9 which is protruded to the outer direction of the cup body is arranged on the push rod 4, the lower end face of the clamping hook 9 is contacted with the upper end face of the clamping groove 8, and the two-stage cup cover 2 is mutually restricted, so that the two-stage cup cover 2 cannot be turned over upwards; thereby locking the primary cup cover 1 and the secondary cup cover 2; the push rod 4 is pushed inwards, and the clamping hook 9 can be moved out of the clamping groove 8 to unlock the primary cup cover 1 and the secondary cup cover 2. As shown in fig. 1.
The push rod 4 is provided with a push surface 10 in the moving direction, the top surface of the first-stage cup cover 1 is correspondingly provided with a blocking surface 11, when the push rod 4 is positioned at the initial position, a gap 12 is arranged between the push surface 10 and the blocking surface 11, the gap 12 can be compressed along with inward pushing of the push rod, and an elastic device for the push rod 4 to rebound back to the initial position after inward pushing is arranged in the gap 12 and is a spring or an elastic rubber block. As shown in fig. 1.
When the cup cover is used, when the secondary cup cover is to be unlocked and drinking water is taken by the suction pipe, the push rod 4 is pushed, the push rod 4 moves towards the inner direction of the cup, the elastic device (namely the space of the compression gap 12) is compressed, the clamping hook 9 also moves inwards and is separated from the clamping groove 8, and therefore the primary cup cover 1 and the secondary cup cover 2 are unlocked; the secondary cup cover 2 is turned over by the elastic sheet and bounces off, at the moment, the pressure lever is separated from the soft suction pipe, the suction pipe stands up to not close the air outlet duct 5 any more, and the part of the suction pipe on the upper surface of the top cover of the primary cup cover 1 is in a sealing state;
meanwhile, the push rod 4 is arranged in the top cover of the first-level cup cover 1 and presses the suction pipe, so that the suction pipe is still sealed; simultaneously, the butt joint air outlet hole moves to the position of the air outlet hole, and the upper and lower sections of hole channels of the air outlet hole are communicated, so that the hot air expanded in the cup is discharged from the air outlet hole channel 5;
therefore, when the secondary cup cover is opened, the push rod 4 presses the suction pipe, so that the suction pipe still keeps sealing, hot water does not enter the suction pipe when the air is discharged and reduced, and the suction pipe is free of hot water when the air pressure in the cup is discharged. When the user drinks water by using the straw, the drinking straw is completely safe, and no hot water is sprayed out.
If the suction pipe is in a completely opened state while hot air is discharged, part of hot water is extruded into the suction pipe to be sprayed out while the air is discharged due to high air pressure in the cup, and the danger of water spraying is also caused by simply making an air outlet hole on the first-stage cup cover 1.
The invention has the advantages of simple and ingenious structure, convenient and quick use, single-hand one-step operation, complete uncovering and deflating operation, no hot water is sprayed out of the suction tube, and safety and reliability.
