Description

The first connecting part 311 and the second connecting part 312 are staggered with each other, so as to avoid stress concentration of the pipe wall of the connecting head 31 and damage.

[0067] In the embodiment, the pipe head 322 is provided with an annular welding rib 3221, and the pipe head 322 is ultrasonically welded with one end of the connecting head 31 through the welding rib 3221, so as to realize the fixed connection of the pipe head 322 and the connecting head 31. The welding rib 3221 is annular, so as to realize the sealing of the pipe head 322 and the connecting head 31.

[0068] In the embodiment, the pipe head 322 is provided with an annular connecting protrusion 3222, and the welding rib 3221 is arranged on one end of the connecting protrusion 3222 away from the pipe head 322; the connecting head 31 is provided with a connecting groove 313 matched with the connecting protrusion 3222. The connecting protrusion 3222 is adapted to be inserted into the connecting groove 313, so as to facilitate the positioning and prevent the misconnection of the pipe head 322 and the connecting head 31.

[0069] The nozzle structure 3 in the embodiment further comprises a sealing member 33, which comprises a tubular body 331 sleeved outside the pipe body 321, one end of the tubular body 331 is provided with a fixed portion 332, the fixed portion 332 is clamped between the pipe head 322 and the connecting head 31, and the ultrasonic welded pipe head 322 and the connecting head 31 press the sealing member 33 therebetween, so that the sealing effect is good; the other end of the tubular body 331 is adapted to be placed in the bottle opening of the water bottle 5 when the water bottle 5 is connected with the second connecting portion 312, so as to realize the sealed connection of the water bottle 5 and prevent gas from overflowing between the water bottle 5 and the connecting head 31, so that the pressure in the water bottle 5 cannot be guaranteed.

[0073] The inner wall of the tubular body 331 and the outer wall of the pipe body 321 have a flow gap 333 therebetween, and when the gas in the water bottle 5 rushes excessively, the excessive gas is discharged through the flow gap 333.

[0074] The outer wall of the other end of the tubular body 331 is provided with an inclined guide surface 3311, so as to facilitate the water bottle 5 to be sleeved outside the tubular body 331, and facilitate the bottle opening of the water bottle 5 to be installed between the tubular body 331 and the second connecting portion 312. The outer diameter of the other end of the tubular body 331 gradually increases in the direction close to the fixed portion 332, so as to form the inclined guide surface 3311.

[0075] The nozzle structure 3 in the embodiment further comprises a sealing gasket 34 connected to one end of the pipe head 322 away from the pipe body 321, and the sealing gasket 34 is provided with a first communication port 342 in communication with the flow communication gap 333 and a second communication port 343 in communication with the lumen of the pipe body 321.

[0076] When the gas in the water bottle 5 is flushed in excess, the excess gas is discharged through the flow communication gap 333 and the first communication port 342. The carbon dioxide gas in the gas cylinder is introduced into the water bottle 5 through the second communication port 343, the lumen, and the injection port provided at the other end of the pipe body 321.

[0081] The elastic member 352 is connected to the air outlet 3512 and has a first state of deforming to open the air outlet 3512 when air is discharged from the air outlet 3512 and a second state of covering the air outlet 3512. When air is discharged, the air pressure of the air inlet 3511 is greater than that of the air outlet 3512, the elastic member 352 deforms under the pressure and opens the air outlet 3512. When air discharge is stopped, the pressure of the air inlet 3511 is equal to or less than that of the air outlet 3512, the elastic member 352 restores to the original state under the action of its own elasticity, blocks the air outlet 3512 and prevents air from flowing back through the air outlet 3512.

[0082] The sealing ring 353 is sleeved on the outer wall of the valve body 351, in interference fit with the cavity wall of the lumen and located between the air inlet 3511 and the air outlet 3512. The sealing ring 353 prevents air from overflowing between the sealing ring 353 and the cavity wall.

[0083] After the inflation is completed, when the air inlet pipeline is in a negative pressure state, the residual pressure of the gas in the water bottle 5 prevents the liquid in the water bottle 5 from flowing back along one end of the pipe body 321 to the direction of the pipe head 322, so that the liquid is not left in the nozzle structure 3 and bacteria are not bred.

[0084] In the nozzle structure 3 in the embodiment, the valve body 351 includes a reduced diameter portion 3514, the air outlet 3512 is arranged on the side of the reduced diameter portion 3514, and the elastic member 352 is an elastic sleeve sleeved on the outside of the reduced diameter portion 3514. The outer diameter of the valve body 351 at the reduced diameter portion 3514 is smaller than the inner diameter of the lumen. The elastic sleeve is much larger than the air outlet 3512 and will not significantly deform under the pressure to be at least partially tightened in the air outlet 3512. Preferably, the air outlet 3512 has two air outlets 3512 coaxially arranged.

Alternatively, the elastic member 352 is a sheet structure, a cover is arranged at the air outlet 3512, and at least part of the elastic member 352 is not connected with the air outlet 3512 and can deform to open the air outlet 3512 under the pressure.

[0086] The nozzle structure 3 in the embodiment further comprises a gas guide needle 36 arranged in the lumen of the pipe body 321, the gas guide needle 36 is provided with a gas guide cavity communicating between two ends of the gas guide needle 36; the gas guide needle 36 is located between the sealing pad 34 and the one-way valve 35, and one end of the gas guide needle 36 extends to the outside of the lumen through the second communication port 343 on the sealing pad 34, and the other end is inserted into the valve cavity 3513 of the one-way valve 35 through the gas inlet 3511. The gas guide needle 36 is suitable for guiding gas to the one-way valve 35 to prevent gas leakage. One end of the gas guide needle 36 has a sharp end, which is suitable for piercing the portable gas bubble water machine when the nozzle structure 3 is used for the portable gas bubble water machine.

[0087] The nozzle structure 3 in the embodiment, the outer periphery of the gas guide needle 36 is sleeved with a sealing part, and the sealing part is in interference fit with the cavity wall of the valve cavity 3513. Alternatively, the gas guide needle 36 has an expanded neck part, which is arranged on the one-way valve 35 through the expanded neck part.
