[0052] The water bottle in this embodiment is a container bottle, which can be used to hold water or beverages such as juice. The gas tank 23 contains carbon dioxide gas, and no excessive restrictions are made here.

[0053] Specifically, Figure 3 As shown, the housing 21 in this embodiment includes a body 211, a second bracket 212 is provided in the body 211, a receiving hole 213 is provided on the second bracket 212, a cover structure 223 is placed in the receiving hole 213, a receiving cavity is formed below the second bracket 212, and a gas release device is provided at the upper end of the second bracket 212, one end of the gas release device is suitable for communicating with the water bottle, and the other end is suitable for communicating with the outside, specifically, the gas release device is a gas release valve 24. Among them, the upper end of the second bracket 212 refers to the end close to the thread 2111 on the body 211, and the lower end of the second bracket 212 refers to the direction away from the thread 2111. 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 accommodating hole 213 on the second bracket 212, forming an accommodating cavity below the second bracket 212, and arranging the air release device at the upper end of the second bracket 212, the structure of the body 211 is made more compact, and the air release device can satisfy the pressure relief of the water bottle. As a convertible embodiment, the second bracket 212 can also be arranged separately from the body 211.

[0054] like Figure 7 As shown, 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 213 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 213, 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.

[0055] 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.

[0056] like Figure 7 and Figure 8As shown, the first bracket 221 is provided with a bracket snap 2212, and the inner wall of the receiving hole 213 is provided with a snap groove 2131 that is matched with the bracket snap 2212, which is suitable for the gas tank 23 to be in the working state when the bracket snap 2212 is snapped into the snap groove 2131. The top of the bracket snap 2212 is provided with an inclined surface, which is suitable for guiding the bracket snap 2212 to escape from the snap groove 2131 under the action of external force. By providing the bracket snap 2212 on the first bracket 221, and providing the snap groove 2131 that is matched with the bracket snap 2212 on the inner wall of the receiving hole 213, when the first bracket 221 moves in the receiving hole 213, when the bracket snap 2212 is snapped into the snap groove 2131, the gas tank 23 is in the working state, which is convenient for subsequent use with a water bottle.

[0057] The size of the accommodating space 222 in this embodiment is slightly larger than the size of the gas tank 23. The sizes of the accommodating space 222 and the gas tank 23 are not limited. In this embodiment, when the accommodating space 222 is in a non-deformed state, there is a certain gap between it and the gas tank 23, which is suitable for the deformation of the bracket spring buckle 2212 when the bracket spring buckle 2212 is buckled into the buckle groove 2131, so that the first bracket 221 clamps the gas tank 23. By setting the size of the accommodating space 222 to be slightly larger than the size of the gas tank 23, the gas tank 23 is conveniently placed in the accommodating space 222. At the same time, when the bracket spring buckle 2212 is buckled into the buckle groove 2131, the elastic deformation of the bracket spring buckle 2212 squeezes the gas tank 23, so that the bracket can clamp the gas tank 23, ensure that the gas tank 23 is fixed in the accommodating space 222 of the first bracket 221, and ensure that the gas tank 23 is in a working state, which is convenient for the subsequent preparation of sparkling water with a water bottle.

[0058] Specifically, the accommodating space 222 is a variable size structure, the size of the accommodating space 222 away from the cover structure 223 gradually decreases toward the size of the accommodating space 222 close to the cover structure 223, and the size of the end of the accommodating space 222 close to the cover structure 223 is adapted to the size of the gas tank 23, so that when the bracket snap 2212 is snapped into the snap groove 2131, the part of the accommodating space 222 away from the cover structure 223 clamps the gas tank 23. As a convertible embodiment, the size of the accommodating space 222 can also be a fixed structure.

[0059] In this embodiment, as a variation, an interference fit can be adopted between the accommodating space 222 and the gas tank 23, so as to further improve the clamping effect of the accommodating space 222 on the gas tank 23 itself.

[0060] In order to facilitate connection with a water bottle, the end of the body 211 away from the cover structure 223 is provided with a thread 2111 suitable for threaded connection with a water bottle.

[0061] like Fig. 9 As shown, the second aspect of the present invention provides a sparkling water machine, comprising a machine body 1, on which the above-mentioned portable inflation device 2 is suitable for being placed.

[0062] Specifically, a storage cavity 11 is provided on the top cover of the body 1, and the storage cavity 11 is suitable for placing the portable inflatable device 2. Among them, some card positions are provided in the storage cavity 11 to facilitate the limiting of the portable inflatable device 2, and a cover plate is also provided on the top cover. After the portable inflatable device 2 is placed in the storage cavity 11, the portable inflatable device 2 is covered to prevent dust from entering or falling off. When the portable inflatable device 2 needs to be used, the cover plate can be opened to take it out. By providing the storage cavity 11 on the top cover of the body 1, the portable inflatable device 2 is placed in the storage cavity 11, and the portable inflatable device 2 can be placed in the body 1 by opening the top cover of the body 1, the storage function of the bubble water machine is realized, space is saved, and the use of the bubble water machine is extended, so that the bubble water machine can be used for two purposes. As a convertible embodiment, it is also possible that the storage cavity 11 is provided in other parts of the body 1.

[0063] The bubble water machine is a machine for making bubble water. Its working principle is to control the conduction of the channel of the gas cylinder mouth through the valve body, and then fill the gas into the water bottle through the pipeline, nozzle, etc., so as to achieve the purpose of dissolving the carbon dioxide gas in the solution in the water bottle. The bubble water machine in this embodiment is equipped with a portable gas filling device 2. When a small volume of bubble water is needed, the portable gas filling device 2 can be used to directly fill the carbon dioxide gas in the gas tank 23 into the water bottle connected thereto through the nozzle, so as to achieve the purpose of dissolving carbon dioxide in water to make bubble water.

[0064] The bubble water machine in this embodiment provides a storage chamber 11 in the existing bubble water machine, so as to make full use of the space of the existing bubble water machine, save space and extend the use of the bubble water machine; the portable inflator 2 facilitates the filling and taking of the carbon dioxide gas cylinder 23 by cooperating with the bracket spring buckle 2212 and the buckle groove 2131, and the gas cylinder 23 can be replaced according to the usage to make a proper amount of bubble water without waste; after the standard carbon dioxide gas cylinder of the bubble water machine is used up, the built-in portable inflator 2 can be used to continue making bubble water without immediate ventilation, thereby extending the use frequency of the bubble water machine.

[0065] Combination Figure 2 , Figure 3 , Figure 6 and Figure 7The shell 21 is the mounting base of the first bracket 221 and the cover structure 223. The first bracket 221 passes through the receiving hole 213 set on the shell body 211, and the cover structure 223 is fixedly connected with the first bracket 221 by a buckle 224. The cover structure 223 can make axial movement along the length direction in the receiving hole 213 of the shell 21. The gas tank 23 is a storage base for compressed carbon dioxide gas. The gas tank 23 is a disposable item. The gas tank 23 is set in the receiving space 222 on the first bracket 221. After the gas tank 23 is loaded into the first bracket 221, an external force pushes the first bracket 221 to move in the axial elongation direction along the outer shell 21, and the bracket spring buckle 2212 arranged on the first bracket 221 is squeezed by the buckle groove 2131 on the inner wall of the accommodating hole 213 arranged on the outer shell 21, so that the bracket spring buckle 2212 is deformed and squeezes the gas tank 23, so that the gas tank 23 is kept in the first bracket 221, so that the portable inflatable device 2 is in a working state. The portable inflatable device 2 in a working state is threadedly connected to the nozzle (not shown in the figure) through the thread 2111 arranged on the outer shell 21. When it is screwed in to the bottom and tightened, the needle on the nozzle (not shown in the figure) punctures the gas tank 23, so that the carbon dioxide gas in the gas tank 23 is filled into the water bottle to make sparkling water.

[0066] The portable inflatable device 2 in working state presses the cover structure 223 to make the cover body move axially along the outer shell 21, wherein 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 excessively extending into the accommodating cavity. When the blocking portion of the cover structure 223 abuts against the outer shell 21, the first bracket 221 is partially withdrawn from the accommodating hole 213 of the outer shell 21, and the bracket spring buckle 2212 is in a relaxed state. The gas tank 23 therein can move freely without external force, so that the gas tank 23 can be withdrawn from the first bracket 221. After the gas tank 23 is discarded and recycled, a new unactivated carbon dioxide gas tank 23 can be put back into the first bracket 221 of the portable inflatable device 2, and then the portable inflatable device 2 is placed in the storage cavity 11 of the bubble water machine and stored in the body 1.

[0067] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
