The support seat is arranged in the inner cavity of the teapot plug body, and a water outlet channel is formed between the support seat and the inner side wall of the teapot plug body. The upper end of the water outlet channel forms a water outlet, and the lower end of the water outlet channel forms a water inlet. The rotating opening and closing driving device can drive the sealing sheet to move away from or seal the water inlet. The rotating opening and closing driving device includes a knob and a linkage mechanism. The knob is rotatably arranged on the upper part of the support seat, and the linkage mechanism is arranged in the support seat. The knob is connected with the power input end of the linkage mechanism, and the sealing sheet is connected with the power output end of the linkage mechanism.

[0004] When in use, the switch type teapot plug is screwed onto the teapot body to seal the opening of the teapot body. When water needs to be poured out, the knob can be rotated to drive the sealing sheet to move downward and away from the water inlet of the water outlet channel through the linkage mechanism. At this time, water can enter the water outlet channel through the water outlet channel and be poured out from the water outlet of the water outlet channel. When water does not need to be poured out, the sealing sheet can be moved upward again by rotating the knob to reseal the water inlet of the water outlet channel. At this time, water cannot be poured out.

[0037] The knob 5 is recessed upward along the axial direction parallel to the knob 5 at the end close to the rotating shaft 6, and the first telescopic groove 20 is arranged therein. The first telescopic block 19 is telescopically arranged in the first telescopic groove 20, and the first spring 21 is arranged between the first telescopic block 19 and the first telescopic groove 20 along the telescopic direction of the first telescopic block 19. The two ends of the first spring 21 are fixedly connected with the first telescopic block 19 and the first telescopic groove 20 respectively, and the first spring 21 drives the first telescopic block 19 to partially extend out of the first telescopic groove 20 in the initial state. The rotating shaft 6 is recessed downward along the axial direction parallel to the knob 5 at the end close to the knob 5, and the first insertion groove 35 is arranged therein. When the knob 5 is rotated to be opposite to the first telescopic groove 20 and the first insertion groove 35, the partially extended first telescopic block 19 can be inserted into the first telescopic groove 20 and the first insertion groove 35 at the same time, so that the knob 5 and the rotating shaft 6 are synchronously rotated. Conversely, when the first telescopic block 19 is retracted, it can be separated from the first insertion groove 35, so that the knob 5 is rotated relative to the rotating shaft 6.

[0038] The knob 5 is recessed with a second telescopic groove 25 on one end close to the rotating shaft 6 in parallel with the axial direction of the knob 5, and the second telescopic groove 25 is sealed and guided with a second telescopic block 24 arranged in a telescopic manner, and a tension spring 26 is arranged between the second telescopic block 24 and the second telescopic groove 25 in the telescopic direction of the second telescopic block 24, and the two ends of the tension spring 26 are fixedly connected with the second telescopic block 24 and the second telescopic groove 25 respectively and drive the second telescopic block 24 to be completely accommodated in the second telescopic groove 25 in the initial state. The driving shaft 16 is recessed with a second insertion groove 36 on one end close to the knob 5 in parallel with the axial direction of the knob 5, and when the knob 5 is rotated to be opposite to the second telescopic groove 25 and the second insertion groove 36, the partially protruding second telescopic block 24 can be inserted with the second telescopic groove 25 and the second insertion groove 36 at the same time, so that the knob 5 and the driving shaft 16 are synchronously rotated. Conversely, the second telescopic block 24 can be disengaged from the second insertion groove 36 when it is retracted, so that the knob 5 is rotated relative to the driving shaft 16.

[0039] The knob 5 is recessed with a second telescopic groove 25 on one end close to the rotating shaft 6 in parallel with the axial direction of the knob 5, and the second telescopic groove 25 is sealed and guided with a second telescopic block 24 arranged in a telescopic manner, and a tension spring 26 is arranged between the second telescopic block 24 and the second telescopic groove 25 in the telescopic direction of the second telescopic block 24, and the two ends of the tension spring 26 are fixedly connected with the second telescopic block 24 and the second telescopic groove 25 respectively and drive the second telescopic block 24 to be completely accommodated in the second telescopic groove 25 in the initial state. The driving shaft 16 is recessed with a second insertion groove 36 on one end close to the knob 5 in parallel with the axial direction of the knob 5, and when the knob 5 is rotated to be opposite to the second telescopic groove 25 and the second insertion groove 36, the partially protruding second telescopic block 24 can be inserted with the second telescopic groove 25 and the second insertion groove 36 at the same time, so that the knob 5 and the driving shaft 16 are synchronously rotated.

[0040] The first telescopic block 19 is fixedly provided with a pulling rope 22, the other end of the pulling rope 22 is inserted into the sliding cavity 27 and fixedly connected with the sealing block 28, and the knob 5 is internally provided with an avoiding through slot 23 for the pulling rope 22 to pass through and move.

[0041] When the stopper body 1 needs to be opened or closed, without pressing the drive block 29, the second telescopic block 24 retracts into the second telescopic groove 25 and does not contact the drive shaft 16. The first telescopic block 19 extends partially out of the first telescopic groove 20 and engages with the first slot 35 on the rotating shaft 6. At this time, rotating the knob 5 causes the rotating shaft 6 to rotate synchronously with the knob 5 while the drive shaft 16 remains stationary. The rotation of the rotating shaft 6 causes the drive inclined surface 38 and the protrusion 8 to slide and engage, driving the protrusion 8 to descend. After passing the tooth 9, the protrusion 8 rises elastically under the restoring force of the second spring 11 and abuts against the lower contact surface 10, causing the sealing plate 4 and the stopper body 1 to disengage, and the water outlet channel 2 to open. Conversely, if the knob 5 is rotated in the same direction, the drive inclined surface 38 and the protrusion 8 slide and engage, driving the protrusion 8 to descend. After passing the tooth 9, the protrusion 8 rises elastically and abuts against the higher contact surface 10, causing the sealing plate 4 and the stopper body 1 to abut against each other, and the water outlet channel 2 to close.

[0042] When it is time to steep tea leaves or to stop steeping tea leaves, press the drive block 29. The transmission rod 31 drives the sealing block 28 to move synchronously, squeezing the air in the sliding cavity 27 into the second telescopic groove 25. The increased air pressure in the second telescopic groove 25 drives the second telescopic block 24 to partially extend out of the second telescopic groove 25 and insert into the second slot 36. At the same time, the movement of the sealing block 28 also pulls the first telescopic block 19 back and disengages it from the first slot 35 through the pull rope 22. At this time, press the drive block 29 and rotate the knob 5. The drive shaft 16 rotates synchronously with the knob 5 while the rotating shaft 6 remains stationary. The mounting arc plate 17 and the sealing layer 18 rotate synchronously with the drive shaft 16. When the mounting arc plate 17 rotates forward to abut against one side of the limiting block 33, the filter hole 15 can be opened to allow the storage space 14 to contact the water inside the pot to steep the tea leaves. When the mounting arc plate 17 rotates in the opposite direction to abut against the other side of the limiting block 33, the filter hole 15 is closed, so that the water in the storage space 14 no longer flows with the water inside the pot, and the steeping of the tea leaves is stopped.
