[0029] Reference Figure 1-8As shown, a water bottle protection structure of a sparkling water machine, the water bottle comprises a water bottle cap 2, an air intake and exhaust seat 3 and a water bottle body 4 made of glass, the water bottle body 4 is threadedly sealed with the lower end of the air intake and exhaust seat 3, the water bottle cap 2 covers the air intake and exhaust seat 3, and can drive the air intake and exhaust seat 3 to lock or unscrew the water bottle body 4. An air inlet 31 and an air outlet 32 ​​are arranged on the air intake and exhaust seat 3, and the gap between the air intake and exhaust seat 3 and the water bottle cap 2 forms an exhaust channel connected to the exhaust port 32. An exhaust valve structure 5 is arranged in the exhaust port 32, and the exhaust valve structure 5 adopts the existing design. In the existing design, manual exhaust and automatic exhaust are commonly used. In this embodiment, automatic exhaust is preferred, specifically, a sealing plug and a spring are arranged in the exhaust port 32. When the air pressure in the water bottle reaches a certain value, the sealing plug is moved to overcome the pressure of the spring, thereby making the exhaust port 32 pass through, and allowing the high-pressure gas to flow through the exhaust port 32 and the exhaust channel in sequence until it is discharged to the outside of the water bottle.

[0030] Since the water bottle in this embodiment is made of glass, it is easy to break and explode, especially in the use environment with high internal pressure, so the protective cover 6 proposed in this embodiment is used for protection. The protective cover 6 includes an upper connecting cover 61 and a lower connecting cover 62 which are separately arranged. The upper connecting cover 61 is provided with a connecting port 611 for connecting and fixing with the air inlet base of the bubble water machine 1. The connecting port 611 is cylindrical and protrudes upward and is provided with an external thread. The upper connecting cover 61 and the lower connecting cover 62 are fixed by a set of locking structures 63. The locking structure 63 specifically includes lugs 631 connected to both sides of the lower connecting cover 62, a lever 632 hinged on the lugs 631, and a fastener 633 hinged on the lugs 631 and the lever 632 at the same time. The fastener 633 is engaged with the outer groove 612 of the upper connecting cover by the cam principle when the components rotate. Similar structures can refer to the lock buckle of the stainless steel lunch box in the prior art. It should be noted that the above-mentioned locking structure 63 is only one of the feasible ones, and its main purpose is to lock or separate the upper connecting sleeve 61 and the lower connecting sleeve 62. Locking methods such as threaded connection and buckle connection should also fall within the protection scope of this case. When in use, the upper connecting sleeve 61 is pre-fixed on the sparkling water machine 1, and the water bottle is placed in the lower connecting sleeve 62 and then connected to the upper connecting sleeve 61.

[0031] In order to ensure that the protective sleeve 6 is fixed, the internal water bottle can ensure the air intake connection. The air nozzle 7 is connected to the air intake base of the sparkling water machine 1, and a long air intake needle tube 71 is arranged below the air nozzle 7. The air intake needle tube 71 is inserted into the water bottle cap 2 and connected to the air inlet 31. In order to further improve the sealing effect and the guiding effect, the lower part of the air nozzle 7 is arranged to be an outer cone, and the water bottle cap 2 is provided with a concave 21 and an inner cone matching the shape of the lower part of the air nozzle 7. When connected, the lower part of the air nozzle 7 can be tightly attached to the water bottle cap 2.

[0032] In order to improve the applicability, in particular, to be suitable for water bottles of different heights, the air nozzle 7 is configured to be able to float up and down adaptively. Specifically, the air nozzle 7 includes an upper sleeve 72, an intermediate sleeve 73, and a lower connecting end 74; the upper portion of the upper sleeve 72 is threadedly fastened to the air inlet base, and the lower portion is inserted into the intermediate sleeve 73; the lower portion of the intermediate sleeve 73 is threadedly connected to the lower connecting end 74, and the lower connecting end 74 is configured to be the outer cone mentioned above to match and fit with the water bottle cap 2. Meanwhile, inside the gas nozzle 7, a sealing sleeve 75 is provided between the lower connecting end 74 and the upper sleeve 72. A sealing ring is provided on the upper end of the sealing sleeve 75 to form an upper end seal with the inner wall of the upper sleeve 72. A sealing ring is provided between the lower end of the sealing sleeve 75 and the lower connecting end 74 to form a lower end seal. A spring is provided on the sealing sleeve 75 to provide a force to drive the upper sleeve 72 and the lower connecting end 74 to move away from each other. Meanwhile, the upper part of the air inlet needle tube 71 of the gas nozzle 7 extends to the inside of the sealing sleeve 75. The main function of the sealing sleeve 75 is to allow the high-pressure gas in the upper sleeve 72 to directly enter the air inlet needle tube 71 from the sealing sleeve 75, so that the gas will not escape from the matching gap between the upper sleeve 72 and the middle sleeve 73, thereby avoiding gas leakage.

[0033] In order to facilitate taking out the water bottle, a pull ring 22 is also provided on the water bottle cover 2 .

[0034] In order to further improve the sealing performance, a sealing rubber plug 77 is also provided on the lower connecting end 74, and the sealing rubber plug 77 seals the air inlet needle tube 71. At the same time, sealing rings are provided at the upper and lower ends of the sealing rubber plug 77. The upper sealing ring is used to seal the connection between the sealing sleeve 75, the sealing rubber plug 77 and the lower connecting end 74, and the lower sealing ring is used to seal the connection between the sealing rubber plug 77 and the lower connecting end 74.

[0035] Through the above arrangement, when matching water bottles of different heights, the distance between the upper sleeve 72 and the lower connecting end 74 of the air nozzle 7 can move freely under the action of the spring to closely match the water bottle cap 2.

[0036] A nozzle is also connected to the air intake and exhaust seat 3 of the water bottle, and the nozzle extends from top to bottom. During the production of bubble water, compressed gas enters the nozzle from the air nozzle 7 and is released from the air hole 85 below the nozzle. The lower part of the existing nozzle is often through-connected. After the air intake is stopped, it is easy for gas or solution to flow back from the lower end of the nozzle, which greatly affects the user experience. In order to overcome this problem, further, the lower end of the nozzle in this embodiment is provided with an anti-backflow structure, specifically including a nozzle sleeve 81, a gasket 82, and a movable plug 83; the upper part of the nozzle sleeve 81 is provided with an internal thread, which is fastened with the external thread at the lower end of the nozzle, and the nozzle sleeve 81 is provided with an inner cavity 811, and the movable plug 83 is installed in the inner cavity 811 and can move up and down; the gasket 82 is provided between the movable plug 83 and the lower end of the nozzle, and the gasket 82 is fixed on the step inside the nozzle sleeve 81; at the same time, a spring is provided between the movable plug 83 and the lower end wall of the inner cavity 811. In order to further ensure the sealing performance, the middle part of the movable plug 83 is provided with an annular boss 831, and the upper part is columnar, and a sealing ring is sleeved at the junction of the upper part and the annular boss 831. In the normal state, the movable plug 83 is moved upward and tightly against the sealing ring under the action of the spring; in the intake state, the compressed gas will drive the movable plug 83 to overcome the action of the spring and move downward, so that the previously blocked nozzle outlet can be connected with the inner cavity 811, and then discharged from the lower end of the inner cavity 811 and the air hole 85 at the lower end of the nozzle into the water bottle. When the intake work is completed, the movable plug 83 returns to the normal state under the action of the spring, and the solution or gas in the water bottle will be blocked by the movable plug 83 and cannot flow back to the inside of the nozzle.

[0037] The above is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Simple modifications, equivalent changes or modifications made without departing from the technical solution of the present invention all fall within the protection scope of the present invention.
