[0077] In the nozzle structure 3 of this embodiment, there is a flow gap 333 between the inner wall of the tubular body 331 and the outer wall of the tube body 321. When the gas in the water bottle 5 rushes in excessively, the excessive gas is discharged through the flow gap 333. An inclined guiding surface 3311 is provided on the outer wall of the other end of the tubular body 331, facilitating the water bottle 5 to be sleeved outside the tubular body 331 and facilitating the installation of the bottle mouth of the water bottle 5 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 fixing portion 332, forming an inclined guiding surface 3311.

[0078] The nozzle structure 3 in this embodiment further includes a gasket 34 connected to one end of the tube head 322 facing away from the tube body 321. The gasket 34 is provided with a first communication port 342 communicating with the flow gap 333 and a second communication port 343 communicating with the lumen of the tube body 321. When the gas in the water bottle 5 rushes in excessively, the excessive gas is discharged through the flow gap 333 and the first communication port 342. The carbon dioxide gas in the gas cylinder 4 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 tube body 321.

[0079] In the nozzle structure 3 of this embodiment, a connection through hole is provided on the tube head 322. The gasket 34 is provided with an anti - detachment buckle 341 clamped at the connection through hole. The first communication port 342 is a through hole penetrating the anti - detachment buckle 341.

The outer diameter of the clamping head is larger than the outer diameter of the connection through hole. The clamping head not only plays a role in clamping and positioning but also plays a role in sealing the connection between the connection through hole and the anti - detachment buckle 341. Gas can only be discharged through the first communication port 342.

[0080] The nozzle structure 3 in this embodiment further includes a one-way valve 35 disposed in the lumen of the pipe body 321. After inflation is completed, when the intake pipeline is in a negative pressure state, it prevents the gas residual pressure in the water bottle 5 from pushing the liquid in the water bottle 5 to flow backward along one end of the pipe body 321 towards the pipe head 322, and will not cause the liquid to remain in the nozzle structure 3 and breed bacteria. The one-way valve 35 includes a valve body 351, an elastic member 352, and a sealing ring 353.

[0081] The valve body 351 has a valve cavity 3513 and an air inlet 3511 and an air outlet 3512 communicating with the valve cavity 3513. The air inlet 3511 communicates with the second communication port 343.

[0082] The elastic member 352 is connected to the air outlet 3512 and has a first state in which it deforms to open the air outlet 3512 when air exits the air outlet 3512, and a second state in which it covers the air outlet 3512. When air exits, the air pressure at the air inlet 3511 is greater than the air pressure at the air outlet 3512, and the elastic member 352 deforms under pressure to open the air outlet 3512. When the air outlet stops, the pressure at the air inlet 3511 is equal to or less than the pressure at the air outlet 3512, and the elastic member 352 returns to its original state under its own elastic force to block the air outlet 3512 and prevent gas from flowing back through the air outlet 3512.

[0083] The sealing ring 353 is sleeved on the outer side wall of the valve body 351 and is in interference fit with the wall of the lumen, and is located between the air inlet 3511 and the air outlet 3512. It prevents gas from overflowing between the sealing ring 353 and the lumen wall.

[0084] In the nozzle structure 3 of this embodiment, the valve body 351 includes a reduced-diameter portion 3514, and the air outlet 3512 is provided on the side of the reduced-diameter portion 3514. The elastic member 352 is an elastic sleeve sleeved outside 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 undergo significant deformation under pressure to cause at least part of it to be constricted inside the air outlet 3512. Preferably, there are two air outlets 3512, and the two air outlets 3512 are coaxial.

[0085] In the nozzle structure 3 of this embodiment, a gas guiding needle 36 is further included and disposed in the lumen of the pipe body 321. A gas guiding cavity is provided on the gas guiding needle 36 to communicate the two ends of the gas guiding needle 36. The gas guiding needle 36 is located between the gasket 34 and the one-way valve 35. One end of the gas guiding needle 36 extends to the outside of the lumen through the second communication port 343 on the gasket 34, and the other end is inserted into the valve cavity 3513 of the one-way valve 35 through the air inlet 3511. The gas guiding needle 36 is adapted to guide gas to the one-way valve 35 to prevent gas leakage. One end of the gas guiding needle 36 has a tip, which is adapted to puncture the gas cylinder 23 of the portable inflating device 2 for inflation.

[0086] In this embodiment, the portable inflating device 2 includes: a housing 21; a cover assembly 22. A receiving space 222 is provided on the cover assembly 22. The cover assembly 22 is adapted to be movably disposed in the housing 21 under the action of an external force. The gas cylinder 23 is adapted to be disposed in the receiving space 222.

Among them, the second bracket 212 can be integrally formed with the inner wall of the body 211. By arranging the second bracket 212 in the body 211, arranging the receiving hole on the second bracket 212, forming a receiving cavity at the lower end of the second bracket 212, and arranging the degassing device at the upper end of the second bracket 212, the structure of the body 211 is more compact, and the degassing device can satisfy the pressure relief of the water bottle. As a convertible embodiment, it is also possible that the second bracket 212 and the body 211 are separately arranged.

[0090] The cover assembly 22 includes: a first bracket 221, on which the accommodation space 222 is provided, which is suitable for being movably arranged in the accommodation hole under the action of external force; and a cover structure 223, which is detachably connected to the first bracket 221, and is suitable for being movably arranged in the accommodation cavity under the action of external force. By setting the cover assembly 22 to include a detachably connected first bracket 221 and a cover structure 223, under the action of external force, the first bracket 221 can be movably arranged in the accommodation hole, and the cover structure 223 can be movably arranged in the accommodation cavity, which can more conveniently ensure that the gas tank 23 is switched between the working state and the storage state, and the structure is relatively simple.

[0091] In order to facilitate the detachable connection between the cover structure 223 and the first bracket 221, the structure is relatively simple. In this embodiment, the cover structure 223 is provided with a buckle 224, and the first bracket 221 is provided with a slot 2211 that cooperates with the buckle 224. As a convertible implementation, the cover structure 223 may be provided with a slot, and the first bracket 221 may be provided with a buckle that cooperates with the slot.

[0092] The first bracket 221 is provided with a bracket snap buckle, and the inner wall of the receiving hole is provided with a buckle groove that cooperates with the bracket snap buckle, which is suitable for the gas tank 23 to be in the working state when the bracket snap buckle is buckled into the buckle groove. Among them, the top of the bracket snap buckle is provided with an inclined surface, which is suitable for guiding the bracket snap buckle to escape from the buckle groove under the action of external force. By providing a bracket snap buckle on the first bracket 221, and providing a buckle groove that cooperates with the bracket snap buckle on the inner wall of the receiving hole, when the first bracket 221 moves in the receiving hole, it moves to the point where the bracket snap buckle is buckled into the buckle groove, and the gas tank 23 is in the working state, which is convenient for subsequent use with a water bottle.

[0093] In this embodiment, the size of the accommodation space 222 is slightly larger than the size of the gas cylinder 23. When the bracket spring buckle is snapped into the buckle groove, the deformation of the bracket spring buckle causes the bracket to clamp the gas cylinder 23. By setting the size of the accommodation space 222 to be slightly larger than the size of the gas cylinder 23, it is convenient to place the gas cylinder 23 in the accommodation space 222. At the same time, when the bracket spring buckle is snapped into the buckle groove, the elastic deformation of the bracket spring buckle squeezes the gas cylinder 23, enabling the bracket to clamp the gas cylinder 23, ensuring that the gas cylinder 23 is fixed in the accommodation space 222 of the first bracket 221, ensuring that the gas cylinder 23 is in a working state, and facilitating the subsequent preparation of sparkling water in cooperation with a water bottle.

[0094] Specifically, the accommodation space 222 has a variable-size structure. The size of the accommodation space 222 away from the cover structure 223 gradually decreases towards the size of the accommodation space 222 close to the cover structure 223. The size of the end of the accommodation space 222 close to the cover structure 223 is adapted to the size of the gas cylinder 23. When the bracket spring buckle is snapped into the buckle groove, the part of the accommodation space 222 away from the cover structure 223 clamps the gas cylinder 23. As an alternative embodiment, the size of the accommodation space 222 can also be a fixed structure.

[0095] To facilitate connection with a water bottle, a third connection portion 2111 is provided at the end of the body 211 away from the cover structure 223, which is adapted to be connected to the first connection portion of the nozzle structure. Preferably, the third connection portion 2111 is a threaded structure.

[0096] Through the cooperation of the bracket spring buckle and the buckle groove of the portable inflation device 2, the loading and removal of the carbon dioxide gas cylinder 23 are convenient. The gas cylinder 23 can be replaced according to the usage amount to make an appropriate amount of sparkling water without waste. After the standard carbon dioxide gas cylinder of the sparkling water machine is used up, the built-in portable inflation device 2 can be used to continue making sparkling water without having to change the gas immediately, extending the usage frequency of the sparkling water machine.

[0097] The housing 21 is the mounting base for the first bracket 221 and the cover structure 223. The first bracket 221 passes through the accommodation hole provided in the body 211 of the housing 21, and then the cover structure 223 is fixedly connected to the first bracket 221 by buckling with a buckle 224. The cover structure 223 can move axially along the length direction within the accommodation hole of the housing 21. The gas cylinder 23 is the storage base for compressed carbon dioxide gas. The gas cylinder 23 is a single-use item and is arranged in the accommodation space 222 on the first bracket 221. After the gas cylinder 23 is loaded into the first bracket 221, an external force pushes the first bracket 221 to move in the axially elongated direction along the housing 21. The bracket spring buckle provided on the first bracket 221 is squeezed against the buckle groove on the inner wall of the accommodation hole of the housing 21, deforming the bracket spring buckle to squeeze the gas cylinder 23, so that the gas cylinder 23 is held within the first bracket 221, thereby putting the portable inflation device 2 into a working state. In the working state of the portable inflation device 2, it is connected to the first connecting portion on the nozzle structure through the third connecting portion 2111 provided on the housing 21. When screwed in and tightened to the end, the air guide needle on the nozzle (not shown in the figure) pierces the gas cylinder 23, so as to fill the carbon dioxide gas in the gas cylinder 23 into a water bottle to make sparkling water.

[0098] In this embodiment, the gas cylinder 23 can be directly placed outside the portable inflation device. When inflation operation is required, the gas cylinder 23 is placed inside the accommodation space 222; it can also be directly placed inside the accommodation space 222 to form an integral structure with the entire portable inflation device.

[0099] The portable inflation device 2 in the working state makes the cover move axially along the housing 21 by pressing the cover structure 223. A blocking portion is provided at the end of the cover structure 223 away from the second bracket 212 to prevent the cover structure 223 from extending excessively into the accommodation cavity. When the blocking portion of the cover structure 223 abuts against the housing 21, a part of the first bracket 221 is withdrawn from the accommodation hole of the housing 21, and the bracket spring buckle is in a relaxed state. The gas cylinder 23 inside it can move freely without external force, so that the gas cylinder 23 can be withdrawn from the first bracket 221. After the gas cylinder 23 is discarded and recycled, a new unused carbon dioxide gas cylinder 23 can be re-placed into the first bracket 221 of the portable inflation device 2, and then the portable inflation device 2 is placed in the storage space of the sparkling water machine and stored in the body 1.
