[0001] The present invention relates to the field of carbonated water makers, and more particularly to a carbonated water maker with an adapter. [Background technology]

[0002] A carbonated water maker is a device for producing carbonated water, and typically uses a carbon dioxide cylinder as a gas supply source, such as the carbonated water maker described in Patent No. 112890595A. The carbon dioxide cylinder has a connecting screw at the top for screwing into the carbonated water maker, which causes a problem: the carbon dioxide cylinder must be rotated and screwed into the carbonated water maker multiple times to secure the carbon dioxide cylinder to the carbonated water maker. However, to prevent the carbon dioxide cylinder from being directly exposed to the air, a cavity is provided to accommodate the carbon dioxide cylinder. However, the space of this cavity is limited, so during installation, the carbon dioxide cylinder must first be placed into the cavity and then screwed into the gas supply assembly of the carbonated water maker, making the installation process relatively tedious. Summary of the Invention [Problem to be solved by the invention]

[0003] In order to solve the above problem, the present invention aims to provide a carbonated water maker with an adapter, which allows the carbon dioxide cylinder to be screwed onto the adapter and then quickly attached to the carbonated water maker using the adapter.

[0021] Referring to Figures 1 to 7, the carbonated water maker with adapter 30 is a carbonated water maker body (10) including a gas supply assembly (20) connected to a gas cylinder and a gas injection means connected to a water cylinder, wherein a mounting hole (21) is provided at the bottom of the gas supply assembly (20), and at least two mounting slots (24) are provided on the inner wall of the mounting hole (21), and the mounting slots (24) include an elevation groove (242) extending to the bottom surface of the mounting hole (21) and a lateral groove (241) connected to the top of the elevation groove (242), and the gas supply assembly (20) is provided with a movable ejector rod (23) located at the center of the top of the mounting hole (21); a drive switch provided in the carbonated water maker main body 10 and connected to the movable ejector rod 23 for driving the movable ejector rod 23 to move up and down; The adapter 30 has a locking hole 301 at its bottom, a first connecting screw on the inner wall of the locking hole 301, a communicating hole 302 that penetrates to the top of the locking hole 301 at its top, and a positioning lock pin 34 that is movable along the mounting slot 24 on the outer periphery of the upper end of the adapter 30, and when the adapter 30 is mounted in the mounting hole 21, the movable ejector rod 23 faces directly toward the communicating hole 302.

[0022] During installation, the adapter 30 is first removed, the carbon dioxide cylinder 40 is screwed into the locking hole 301 at the bottom of the adapter 30, and then the carbon dioxide cylinder 40 and the adapter 30 are synchronously inserted into the mounting hole 21 at the bottom of the gas supply assembly 20, causing the positioning locking pin 34 to move upward along the lifting groove 242. Once it reaches the top of the lifting groove 242, the carbon dioxide cylinder 40 is rotated to rotate the adapter 30, causing the positioning locking pin 34 to move along the lateral groove 241 to the end of the lateral groove 241, where it is restrained by the bottom of the lateral groove 241, further locking the carbon dioxide cylinder 40 to the gas supply assembly 20. With this solution, when the carbon dioxide cylinder 40 is installed in the gas supply assembly 20, only a slight rotation is required to complete the fixation, making the installation process easier and with less impact on the operation of the cavity that receives the carbon dioxide cylinder 40.

[0023] In the above configuration, the mounting slot 24 may be mounted on the top of the adapter, and the positioning lock pin 34 may be mounted on the inner wall of the mounting hole 21.

[0024] In this case, it is preferable that the horizontal arc central angle of the front and rear ends of the mounting slot 24 is 20 to 60 degrees based on the central axis of the mounting hole 21, so that after the carbon dioxide cylinder 40 is attached to the adapter 30, the rotation range when the adapter 30 is inserted into the mounting hole 21 of the gas supply assembly 20 is 20 to 60 degrees.

[0025] Preferably, the adapter 30 has a plurality of elastic pieces 35 at its upper end, each of which has a positioning bump 351 at its top, and the gas supply assembly 20 has a positioning hole at its bottom that surrounds the mounting hole 21. When the positioning lock pin 34 moves to the end of the lateral groove 241, the positioning bumps 351 engage with the positioning holes, thereby fulfilling the role of positioning and fixing. At the same time, the positioning bumps 351 are fitted into the positioning holes by the elastic pieces, producing a tactile sensation and sound, allowing the user to more clearly confirm that the adapter 30 has been rotated to the desired position. Preferably, the positioning holes are strip-shaped grooves 25 that extend toward the center of the mounting hole 21. In another embodiment, the positioning holes may be blind holes.

[0026] In this proposal, preferably, the adapter 30 includes a main cover 31 and a sub-cover 32 provided at the center of the top of the main cover 31, the locking hole 301 is provided at the bottom of the sub-cover 32, the communicating hole 302 is provided at the center of the top of the sub-cover 32, the positioning lock pin 34 is provided on the outer periphery of the sub-cover 32, the elastic piece 35 is provided at the top of the main cover 31 and is located outside the sub-cover 32, and the bottom of the main cover 31 is used to cover the outer periphery of the top of the carbon dioxide cylinder 40.

[0027] In the present invention, the positioning bump 351 is preferably located directly below the positioning lock pin 34 .

[0028] Preferably, a gas inlet hole 22 is provided at the top of the mounting hole 21, the movable ejector rod 23 is provided within the gas inlet hole 22, a connector 33 is provided at the top of the adapter 30, a seal ring 331 is provided on the side wall of the connector 33 to seal with the inner wall of the gas inlet hole 22, and the communicating hole 302 is provided at the top of the connector 33, thereby improving the sealing performance.

[0029] In this embodiment, in order to make it easier to insert the positioning lock pin 34 into the lifting groove 242, it is preferable that the bottom of the lifting groove 242 is bell-mouth shaped, and it is more preferable that the lateral groove 241 is arranged horizontally.

[0030] In this proposal, preferably, an arc-shaped transition groove 36 is disposed at the junction between the top and side surfaces of sub-cover 32, and reinforcing ribs 37 are provided on the surface of said arc-shaped transition groove 36, the ends of which are connected to the top surface of sub-cover 32 and the top of the side surface of sub-cover 32, respectively. With this configuration, stress concentration at the junction between the top and side surfaces of sub-cover 32 is avoided during the manufacture of adapter 30, thereby avoiding the problem of the adapter being susceptible to cracking after long-term use.

[0031] In another embodiment, the lateral groove 241 may be arranged in a configuration inclined downward toward the end. Alternatively, a protruding stopper 243 may be provided in the center of the lateral groove 241 to restrict movement of the positioning lock pin 34 in its natural state. Preferably, the protruding stopper 243 is provided at the tip end of the lateral groove 241.

[0032] The above is merely a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any direct or indirect application of the conversion to an equivalent configuration made using the contents of the specification and drawings of the present invention under the concept of the present invention in other related technical fields is all included in the patent protection scope of the present invention.
