[0038] In the present embodiment, when the milk tea bucket 200 needs to be cleaned, the first plug 100 and the second plug 110 can be separated from each other, and during separation, the first plug 100 and the second plug 110 are separated by the adjusting component 320 while stopping the flow. During cleaning, the position of the movable block 323 can be quickly adjusted to change the flow stopping state of the first plug 100, and the residual milk tea in the milk tea bucket 200 can be guided to be discharged through the first plug 100 faster. At the same time, the cleaning liquid can also be guided to clean the inside of the first plug 100 to avoid cleaning dead corners. The connecting component 330 can automatically pop off and separate from the first plug 100 when it contacts the second plug 110, making the separation process more convenient.

[0039] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the adjustment component 320 includes a first spring 324 fixedly installed on the top of the movable block 323, the other end of the first spring 324 is fixedly connected to the inner top wall of the sealing tube 321, the connecting tube 111 is fixedly installed inside the second plug 110, the connecting tube 111 is located at the bottom end of the sealing tube 321 and is tightly pressed against the bottom end of the sealing tube 321, and a push rod 325 is fixedly installed inside the connecting tube 111, and the push rod 325 is in contact with the movable block 323.

[0040] The adjustment assembly 320 also includes an adjustment block 328 arranged at the top of the sealing tube 321, and an adjustment groove 329 is opened inside the adjustment block 328. A support rod 3210 is slidably connected to one side of the adjustment groove 329. One end of the support rod 3210 extends into the interior of the sealing tube 321 and is fixedly connected to the top of the movable block 323. Limiting blocks 3211 are fixedly installed on both sides of the surface of the support rod 3210, and a limiting groove 3212 is opened on the top of the sealing tube 321.

[0041] The top of the movable block 323 is fixedly connected with a shielding tube 327, and the shielding tube 327 is slidably connected to the inner wall of the sealing tube 321. The bottom of the adjusting block 328 is fixedly installed with a guide ring 3213, and the guide ring 3213 is sleeved on the outside of the sealing tube 321. The outside of the guide ring 3213 is set to be inclined. The top of the adjusting block 328 is fixedly installed with a driving block 3214.

[0042] The limiting groove 3212 is configured as a strip groove, and the bottoms of the two limiting blocks 3211 are configured as inclined surfaces.

[0043] A guide groove 311 is provided at the top of the guide block 310, and the guide groove 311 is set in a funnel shape. A spiral groove 322 is provided on the surface of the guide groove 311. The bottom end of the push rod 325 is fixedly connected to a guide block 326, and the guide block 326 is set in a cone shape.

[0044] In the present embodiment, when the first plug 100 is separated from the second plug 110, the second plug 110 drives the top rod 325 to move downward and no longer presses against the movable block 323. At this time, the first spring 324 moves downward, and synchronously drives its connecting hole 3231 to move downward, and intersects with the connecting hole 3231 of the sealing tube 321, so that the first plug 100 can be stopped when separated. When the movable block 323 moves downward, the shielding tube 327 is synchronously driven to move downward, which can prevent milk tea or debris from entering the sealing tube 321 above the movable block 323 and causing damage to the first spring 324. When it is necessary to adjust the stop state of the first plug 100, the driving block 3214 can be pulled up to allow the driving block 3214 to synchronously drive the shielding tube 327 to move downward. The adjusting block 328 moves, and the adjusting block 328 moves synchronously with the support rod 3210 and the movable block 323. When the two limit blocks 3211 of the support rod 3210 pass through the limit groove 3212, the driving block 3214 is rotated 90°, so that the two limit blocks 3211 can be clamped on the top of the limit groove 3212 to fix the movable block 323. At this time, the movable block 323 is connected with the connecting hole 3231 of the sealing tube 321 again, so that the first plug 100 can be restored to the circulation state. When the first plug 100 is circulated, the guide groove 311 and the spiral groove 322 of the guide block 310 cooperate with each other, which can effectively guide the flow of milk tea or cleaning liquid, make it slide down along the spiral path, and accelerate the discharge and diversion of the liquid.

[0045] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, the connecting assembly 330 includes movable grooves 331 opened on both sides of the second plug 110, and the movable grooves 331 are slidably connected with connecting blocks 332 inside, and a second spring 333 is fixedly connected between the connecting block 332 and the inner wall of the movable groove 331. A mounting groove 335 is opened at the bottom of the guide block 310, and the two connecting blocks 332 of the second plug 110 are both arranged inside the mounting groove 335. Two movable blocks 334 are slidably connected to the two sides of the guide block 310, and the sides of the two movable blocks 334 away from each other extend out of the first plug 100, and the two connecting blocks 332 are respectively aligned with the two movable blocks 334, and one side of the connecting block 332 is in contact with the adjacent movable block 334.

[0046] A side of the connecting block 332 close to the moving block 334 is configured as an inclined surface, and both sides of the inclined surface of the connecting block 332 are configured as rounded corners.

[0047] A piston plate 337 is slidably installed inside the mounting groove 335 . The piston plate 337 is located at the top of the second plug 110 . The bottom of the piston plate 337 contacts the second plug 110 . A third spring 336 is fixedly installed between the top of the piston plate 337 and the top wall inside the mounting groove 335 .

[0048] A fixing ring 338 is fixedly installed at the bottom of the first plug 100. The fixing ring 338 is configured as an internal hollow structure. A sealing airbag 339 is sleeved on the outer side of the fixing ring 338. The interior of the fixing ring 338 is connected to the sealing airbag 339. The fixing ring 338 and the sealing airbag 339 are both located between the second plug 110 and the connecting pipe 111. A plurality of delivery pipes 3310 are fixedly installed on the top of the fixing ring 338. The other ends of the plurality of delivery pipes 3310 extend into the interior of the mounting groove 335 and are located on the top of the piston plate 337.

[0049] In this embodiment, when the first plug 100 and the second plug 110 are connected, one side of the second plug 110 enters the installation groove 335, and synchronously drives the connecting blocks 332 on both sides to be recovered into the corresponding movable grooves 331. When the two connecting blocks 332 move to the side of the corresponding moving blocks 334, the second spring 333 pushes the connecting blocks 332 to move the adjacent moving blocks 334 to the outside of the first plug 100, so that the connection between the first plug 100 and the second plug 110 can be quickly completed. When the second plug 110 enters the installation groove 335, the piston plate 337 is squeezed to squeeze the gas on the upper part of the piston plate 337 into the sealing airbag 339, so that the sealing The airbag 339 expands to seal and reinforce the gap between the second plug 110 and the connecting tube 111, thereby preventing the elastic aging of the traditional rubber sealing ring from affecting the sealing effect. Moreover, since a new inflation seal is performed each time a connection is made, the degradation of the sealing performance caused by long-term use can also be avoided. When separating, the two moving blocks 334 are moved toward the inside of the first plug 100, so that the corresponding connecting blocks 332 are recovered into the movable groove 331 again. At this time, the internal gas reflux of the sealing airbag 339 is used in conjunction with the third spring 336 to reset the piston plate 337, and the second plug 110 is ejected to the outside, making the separation of the first plug 100 and the second plug 110 more convenient.

[0050] Working principle: when the first plug 100 is separated from the second plug 110, the second plug 110 drives the top rod 325 to move downward and no longer presses against the movable block 323. At this time, the first spring 324 moves downward, and synchronously drives its connecting hole 3231 to move downward, and intersects with the connecting hole 3231 of the sealing tube 321, so that the first plug 100 can be stopped when separated. When the movable block 323 moves downward, the shielding tube 327 is synchronously driven to move downward, which can prevent milk tea or debris from entering the sealing tube 321 above the movable block 323 and causing damage to the first spring 324. When it is necessary to adjust the stop state of the first plug 100, the driving block 3214 can be pulled up to allow the driving block 3214 to synchronously drive the adjusting The node block 328 moves, and the adjustment block 328 moves synchronously to move the support rod 3210 and the movable block 323. When the two limit blocks 3211 of the support rod 3210 pass through the limit groove 3212, the driving block 3214 is rotated 90°, so that the two limit blocks 3211 can be clamped on the upper part of the limit groove 3212 to fix the movable block 323. At this time, the movable block 323 is connected with the connecting hole 3231 of the sealing tube 321 again, so that the first plug 100 can be restored to a circulation state. When the first plug 100 is in circulation, the guide groove 311 and the spiral groove 322 of the guide block 310 cooperate with each other, which can effectively guide the flow of milk tea or cleaning liquid, so that it slides down along the spiral path, and accelerates the discharge and diversion of the liquid;

[0051] When the first plug 100 and the second plug 110 are connected, one side of the second plug 110 enters the installation groove 335, and synchronously drives the connecting blocks 332 on both sides to be recovered into the corresponding movable grooves 331. When the two connecting blocks 332 move to the side of the corresponding moving blocks 334, the second spring 333 pushes the connecting blocks 332 to move the adjacent moving blocks 334 to the outside of the first plug 100, so that the connection between the first plug 100 and the second plug 110 can be quickly completed. When the second plug 110 enters the installation groove 335, the piston plate 337 is squeezed to squeeze the gas on the upper part of the piston plate 337 into the sealing airbag 339, so that the sealing airbag 33 9 expands to seal and reinforce the gap between the second plug 110 and the connecting pipe 111, so as to avoid the elastic aging of the traditional rubber sealing ring affecting the sealing effect. Moreover, since a new inflatable seal is performed each time a connection is made, the degradation of the sealing performance caused by long-term use can also be avoided. When separating, the two moving blocks 334 are moved toward the inside of the first plug 100, so that the corresponding connecting blocks 332 are recovered into the movable groove 331 again. At this time, the internal gas reflux of the sealing airbag 339 cooperates with the third spring 336 to reset the piston plate 337, and the second plug 110 is ejected to the outside, so that the first plug 100 and the second plug 110 are separated more conveniently.
