Fig. 1 shows an assembly of the bubble water mixing assembly 12010 in the refrigerator 1, and it is apparent that this assembly is merely exemplary and not exclusive.

As shown in fig. 2 and 3, in the present embodiment, the bubble water mixing assembly 10 includes a mixing module 100, a supply module 200, the supply module 200 for supplying carbon dioxide, the mixing module 100 for preparing a liquid with bubbles, and a storage box 300 for accommodating the mixing module 100 and the supply module 200. Specifically, the mixing module 100 includes a mixing container 110 and a mixing assembly 120, the mixing container 110 being removably disposed on the mixing assembly 120. The supply module 200 includes a carbon dioxide cylinder 210 and a supply assembly 220, and the carbon dioxide cylinder 210 is detachably disposed on the supply assembly 220. Fig. 4 and 5 illustrate a connection relationship between the supply assembly 220 and the mixing assembly 120 in an operating state, and it should be apparent that this connection relationship is merely exemplary and not exclusive.

In a particular embodiment, the bubble-water mixing assembly 10 includes a mixing module 100 and a supply module 200, the mixing module 100 including a mixing vessel 110 and a mixing assembly 120, the mixing assembly 120 including a mixing connection 121 and a pressure relief switch 122. The mixing container 110 is used for containing liquid to be mixed, the mixing connector 121 is used for detachably arranging the mixing container 110 thereon, and the mixing connector 121 is matched with the mixing container 110 to enable the interior of the mixing container 110 to be a closed space; the mixing connection 121 is also in communication with the supply module 200 to allow the mixing vessel 110 mounted thereon to capture carbon dioxide to produce a bubbled liquid; a pressure relief switch 122 for communicating with the mixing vessel 110; and, when opened, places the mixing container 110 in communication with its environment so that the mixing container 110 holding the bubbled liquid is removed.

The shape, type, and the like of the mixing container 110 are not particularly limited, and in the present embodiment, a mixing bottle is used as the mixing container 110. The mixing container 110 contains a liquid to be mixed, carbon dioxide is introduced into the mixing container 110, and the liquid with bubbles is prepared inside the mixing container 110. The mixing vessel 110 has a certain pressure resistance to satisfy the requirement of the mixing vessel 110 for preparing the mixed liquid with bubbles, and the pressure resistance of the mixing vessel 110 is not particularly limited and is designed according to specific working conditions. The specific type of the liquid is not limited, and may be, for example, purified water, fruit juice, etc., and in this embodiment, purified water. When the mixing container 110 is used to prepare a mixed liquid with bubbles, the pressure inside the mixing container 110 is different from the pressure of the environment in which it is placed, and the mixing container 110 is difficult to detach.

Pressure release switch 122 and mixing vessel 110 intercommunication, bubble water is waited to prepare and is accomplished, and pressure release switch 122 makes mixing vessel 110's pressure and ambient pressure equal, and mixing vessel 110 dismantles easily and makes this bubble water mixing assembly 10 possess a lot of advantages. For example, the bubble water mixing assembly 10 can prepare different types of bubble-containing liquids, i.e., if purified water is contained in the mixing container 110, bubble-containing water is prepared, and if fruit juice is contained in the mixing container 110, bubble-containing fruit juice is prepared, which is more user-selectable. The mixing container 110 is easy to clean and prevents the growth of bacteria. The mixing container 110 is prevented from using water stored in the water tank in the refrigerator 1, and a sanitary problem caused by the long-term non-cleaning of the water tank is prevented. The bubble water mixing assembly 10 occupies a small volume.

The mixing connector 121 is used to detachably connect the mixing container 110 thereto, and the mixing container 110 is not limited to be detachable, and may be a screw connection or a snap connection, for example. The specific type of the supply module 200 is not limited, and the supply module 200 may provide a carbon dioxide gas source.

It can be seen that the pressure relief switch 122 allows for easy removal of the mixing container 110, and that the easy removal of the mixing container 110 provides many advantages to the sparkling water mixing assembly 10. For example, the bubble water mixing assembly 10 can prepare different types of bubble-bearing liquids with more flexibility in user selection. The mixing container 110 is easy to clean and prevents the growth of bacteria. The mixing container 110 is prevented from using water stored in the water tank in the refrigerator 1, and a sanitary problem caused by the long-term non-cleaning of the water tank is prevented. The bubble water mixing assembly 10 occupies a small volume.

In other embodiments, as shown in fig. 3-7, the supply module 200 includes a carbon dioxide cylinder 210 and a supply connection 221, the supply connection 221 being for the carbon dioxide cylinder 210 to be removably disposed thereon; the supply connection 221 communicates with the mixing connection 121 so that the carbon dioxide cylinder 210 mounted thereon supplies carbon dioxide to the mixing vessel 110.

The carbon dioxide gas cylinder 210 is easily disassembled and assembled by the arrangement and connection of the supply connection member 221, so that frequent replacement of pipeline connection caused when the carbon dioxide gas cylinder 210 is replaced is avoided, and the problems of pipeline aging and sealing are further caused.

In other embodiments, as shown in fig. 7, the supply connector 221 has a push switch 222, and the push switch 222 is used for controlling the opening and closing of the carbon dioxide cylinder 210.

In a specific use process, the switch 222 is pressed to prepare bubble water, and a user generally cannot forget, but the pressure relief switch 122 may forget to operate, so that a certain trouble is caused to the user, and the arrangement can avoid pressing too many keys. The operation of the pressure relief switch 122 is after the press switch 222, if the user forgets the operation steps, that is, the pressure relief switch 122 is turned on first, and then the press switch 222 is turned on, the bubble water cannot be prepared, the operation steps are many, and the inconvenience is brought to the user by the need of a certain sequence. In the present embodiment, this arrangement has many advantages, and the user only turns on the push switch 222, the pressure relief switch 122 will automatically turn off, and the bubble water starts to be prepared; when the bubble water is prepared, the user simply turns off the push switch 222, and the pressure relief switch 122 is automatically turned on, thereby facilitating the disassembly of the mixing container 110. Therefore, the linkage of the push switch 222 and the pressure relief switch 122 in this embodiment makes the bubble-water mixing assembly 10 easy to operate, avoids errors, avoids too many buttons, strict operation steps, and avoids causing certain troubles to users.

In other embodiments, as shown in fig. 3-8, pressure relief switch 122 is in communication with mixing connection 121 such that mixing vessel 110 mounted on mixing connection 121 is in communication with pressure relief switch 122. The pressure relief switch 122 is connected to the mixing connector 121, so that the mixing container 110 has universality, that is, the mixing container 110 only needs to be matched with the mixing connector 121, and the mixing container 110 can be depressurized under the control of the pressure relief switch 122 without configuring other devices.

Specifically, as shown in fig. 1 to 8, a mouth of the carbon dioxide gas cylinder 210 is provided with a flip cover, and the flip cover is flipped up and down relative to the carbon dioxide gas cylinder 210 to open or close the carbon dioxide gas cylinder 210. The supply connection 221 is used to detachably mount the carbon dioxide cylinder 210 thereon, the supply connection 221 has a gas chamber 2212, a supply passage 2211, and a push switch 222, and the push switch 222 has a first push bar 2221. The gas cavity 2212 is used for enabling the bottle mouth to extend upwards into the gas cavity; a supply passage 2211 communicates with the gas cavity 2212, and the supply passage 2211 is used for delivering carbon dioxide. The first plunger 2221 is inserted into the upper end of the flip through the gas chamber 2212, and moves up and down relative to the flip to open or close the carbon dioxide cylinder 210, so that the supply passage 2211 delivers carbon dioxide to the outside or stops delivering carbon dioxide.

The size of the carbon dioxide cylinder 210 is not limited, and the position of the opening of the cylinder is also not limited, for example, in the embodiment, the opening of the cylinder is located at the top of the carbon dioxide cylinder 210. The size of the flip cover is not limited, and the flip cover can be turned up and down relative to the carbon dioxide gas cylinder 210 to open and close the carbon dioxide gas cylinder 210.

The supply connector 221 is used to detachably mount the carbon dioxide cylinder 210 thereon, and the specific detachment is not limited in any way, and may be, for example, a snap fit or a screw fit.

The first top rod 2221 extends into the upper end of the flip cover through the gas cavity 2212, the first top rod 2221 is pressed, the flip cover is pressed downwards by the first top rod 2221, and the carbon dioxide gas bottle 210 is opened; the first push rod 2221 stops being pressed, and the pressure in the carbon dioxide cylinder 210 moves upward against the flip cover to close the carbon dioxide cylinder 210. The first plunger 2221 may have any specific shape, such as a shape that can move up and down with respect to the lid to open or close the carbon dioxide cylinder 210.

Therefore, the bubble-water mixing assembly 10 provided by the embodiment has the advantages of simple structure, easiness in assembly and simplicity in operation. The supply connection 221 allows the carbon dioxide cylinder 210 to be easily replaced so that the carbon dioxide cylinder 210 can be controllably discharged with carbon dioxide without having to remove much of the connection piping.

Specifically, as shown in fig. 8, the pressure relief switch 122, the interface portion 2224, and the gas chamber 2212 are sequentially arranged along the extending direction of the lever 2223; first plunger 2221 is located directly below a first end of lever 2223, and pressure relief switch 122 is located directly below a second end of lever 2223. The arrangement mode saves space and enables the structure to be compact.

Specifically, as shown in fig. 9 to 10, the pressure relief switch 122 includes a second ejector 1221, an exhaust pipe 1222, a blocking block 1223, and a compression spring 1224. The second ejector 1221 is located directly below the second end. The exhaust pipe 1222 is sleeved at the lower end of the second push rod 1221, and the exhaust pipe 1222 has a blocking section gradually widening downward for communicating with the mixing container 110 and the environment where the mixing container is located. The plugging block 1223 is disposed in the plugging section of the exhaust pipe 1222, and the plugging block 1223 is gradually widened downward. A pressure spring 1224 is arranged between the bottom of the plugging section and the plugging block 1223; when the first end of the lever 2223 is pressed downwards, the second end of the lever 2223 removes the extrusion on the second ejector rod 1221, the blocking block 1223 moves upwards under the elastic force of the pressure spring 1224, and the pressure relief switch 122 stops communicating with the environment where the pressure relief switch is located; when the lever 2223 is reset, the second end of the lever 2223 presses the upper end of the second push rod 1221, the blocking block 1223 moves downwards, and the pressure relief switch 122 is communicated with the environment.

In this embodiment, the second push rod 1221 is located right below the second end, which is beneficial for the second end of the first push rod 2221 to apply downward pressure to it to control the opening and closing of the pressure relief switch 122. Specifically, the lower end and the side surface (the side surface refers to the side surface at the upper end of the blocking segment) of the exhaust pipe 1222 are respectively communicated with the environment where the exhaust pipe 1222 is located and the mixing container 110, that is, the lower end of the exhaust pipe 1222 is communicated with the environment where the exhaust pipe 1222 is located, the side surface of the exhaust pipe 1222 is communicated with the mixing container 110, and the mixing container 110 is communicated with the environment where the exhaust pipe 1222 is located. In this embodiment, the exhaust pipe 1222 has a blocking section which is gradually widened downwards, the blocking block 1223 is gradually widened downwards, the pressure spring 1224 is arranged between the bottom of the blocking section and the blocking block 1223, the first end of the lever 2223 is pressed, the first push rod 2221 moves downwards, the carbon dioxide container is opened, and bubble water preparation starts; the second end of the lever 2223 no longer applies pressure to the second push rod 1221, the pressure spring 1224 supports the blocking block 1223 to move upwards, and due to the fact that the blocking block 1223 is wide downwards, the blocking block 1223 blocks the blocking section upwards, communication between the mixing container 110 and the environment is prevented, and the pressure relief switch 122 is closed. Stopping pressing the first end of the lever 2223, the lever 2223 is reset, the second end of the lever 2223 applies pressure to the second ejector rod 1221, the second ejector rod 1221 pushes the pressing block 1243 to move downwards, the blocking section is not blocked due to the lower width of the blocking section, and the mixing container 110 is communicated with the environment. It should be apparent that the particular shape and arrangement of the components included in the pressure relief switch 122 in this embodiment are exemplary only and not exclusive. This kind of setting mode makes bubble water mixing assembly 10 practice thrift the space, makes compact structure, and the linkage of press switch 222 and pressure release switch 122 in this embodiment makes bubble water mixing assembly 10 easy to operate, avoids the error, avoids the button too many, operating procedure is harsh, avoids causing certain puzzlement to the user.
