[0018] When making sparkling water with a sparkling water machine, the gas cylinder interface of the gas cylinder connector is connected to a high-pressure gas cylinder, and the water bottle interface of the water bottle connector is connected to a water bottle filled with water. By pressing down the gas cylinder thimble with a pressing plate, the gas cylinder thimble triggers the inflation valve on the gas cylinder to open it. At this time, the free end of the pressing plate rotates downward, the end of the pressing block close to the pressing plate rotates downward, and the end close to the exhaust thimble rotates upward. The first spring pushes the valve core to block the valve port, and the exhaust valve closes. The high-pressure gas in the gas cylinder enters the injection pipe through the pipeline and is injected into the water in the water bottle through the injection pipe to complete the production of sparkling water. After the sparkling water is made, release the pressing plate. The pressing plate rotates upward under the action of the second spring. The free end of the pressing plate pushes the end of the pressing plate close to the pressing plate to rotate upward, and the end close to the exhaust thimble rotates downward, causing the pressing block to press down the exhaust thimble. The exhaust thimble overcomes the elastic force of the first spring and pushes the valve core to move downward to open the valve port, and the exhaust valve opens. In this way, the excess high-pressure gas in the gas cylinder can be discharged through the exhaust valve.

[0019] Therefore, when pressing down the pressing plate in this application, the exhaust valve automatically closes, and when releasing the pressing plate, the exhaust valve automatically opens. The exhaust valve does not require manual operation, which is convenient for operation. Moreover, the force for the exhaust thimble to push the valve core to open comes from the elastic force of the second spring, and at the same time, the first spring can provide an elastic force to prevent the valve core from opening, which is convenient for controlling the opening degree of the exhaust valve, and thus convenient for controlling the exhaust speed of the exhaust valve, solving the problem of water backflow from the water bottle during exhaust.

[0030] It should be noted that the gas release valve on the gas cylinder is a prior art, and its internal is provided with a valve core and a spring. When the gas cylinder thimble touches the valve core of the gas release valve, the gas release valve opens. When the gas cylinder thimble separates from the gas release valve, the valve core of the gas release valve automatically resets under the action of the spring, and the gas release valve automatically closes.

[0031] In order to prevent air leakage between the gas cylinder thimble 240 and the thimble guide hole 220, a first annular groove is provided on the outer periphery of the gas cylinder thimble 240, and a first sealing ring is provided in the first annular groove. The first sealing ring is in sealing contact with the thimble guide hole 220.

[0032] Reference Figure 2 Figure 2 , the lower part of the water bottle connector 300 is provided with a water bottle interface 310 for docking with the water bottle.

One end of the air inlet interface 320 located at the water bottle interface 310 is connected with an air injection pipe 340 for extending into the water bottle.

[0033] A one-way valve is arranged in the air inlet interface 320. The one-way valve allows the injected gas to pass through unidirectionally and can prevent the bubble water in the gas cylinder from flowing back in reverse.

[0034] Reference Figure 2 Figure 2 , the exhaust valve 400 includes a valve body 410, a valve core 420 and an exhaust ejector pin 430. An upper cavity 411, a lower cavity 412 and a valve seat 413 located between the upper cavity 411 and the lower cavity 412 are arranged in the valve body 410. A valve hole is arranged at the center of the valve seat 413, and a valve port is arranged at the lower end of the valve hole. The valve core 420 is adapted to be inside the valve port. A first spring 440 supporting the lower side of the valve core 420 is arranged in the lower cavity 412. The exhaust ejector pin 430 is slidably adapted to be inside the upper cavity 411. The lower end of the exhaust ejector pin 430 has a top shaft 431 extending into the valve hole. An exhaust inlet 414 communicating with the lower cavity 412 and an exhaust outlet 415 communicating with the valve hole are arranged outside the valve body 410. A pipeline is connected between the exhaust inlet 414 and the first exhaust port 330.

[0035] In order to prevent air leakage between the exhaust ejector pin 430 and the upper cavity 411, a second annular groove is arranged on the outer periphery of the exhaust ejector pin 430, and a second sealing ring is arranged in the second annular groove. The second sealing ring is in sealing contact with the upper cavity 411.

[0036] In order to facilitate the installation and adjustment of the first spring 440, a threaded interface extending to the lower end of the lower cavity 412 is arranged at the lower end of the valve body 410, and a threaded plug 416 supporting the lower end of the first spring 440 is threadedly connected in the threaded interface.

[0037] Reference Figure 1 and Figure 4 Figure 4 , the driving assembly 500 includes a pressing plate 510 and a pressing block 520. The pressing plate 510 presses on the upper end of the gas cylinder ejector pin 240. One end of the pressing plate 510 is hinged on the frame 100. A second spring 511 is supported between the pressing plate 510 and the water bottle connector 200. The middle of the pressing block 520 is hinged on the frame 100. One end of the pressing block 520 presses on the upper side of the pressing plate 510 near the free end side, and the lower side of the other end of the pressing block 520 presses on the upper end of the exhaust ejector pin 430.

[0038] The driving assembly 500 further includes a driving handle 530. One end of the driving handle 530 is provided with a driving rotating shaft 531. The driving rotating shaft 531 is arranged on the upper side of the pressing plate 510 and is rotatably installed on the frame 100. A cam 532 pressing on the upper side of the pressing plate 510 is provided on the driving rotating shaft 531. When the driving handle 530 is rotated downward, the pressing plate 510 can be driven to rotate downward through the cam 532. When the handle is released, the pressing plate 510 will rotate upward and reset under the action of the second spring 511.

[0039] Referring to Figure 1 and Figure 3 , an upper portion of the water bottle connector 300 is provided with a second exhaust port 350 accessing the water bottle interface 310. A safety valve is provided in the second exhaust port 350. When the air pressure in the water bottle exceeds the specified value, pressure relief can be performed through the safety valve, thereby ensuring safe use.

[0040] Referring to Figure 3 , an exhaust member 600 is installed on the frame 100. The exhaust member 600 has a first interface 610, a second interface 620, and an exhaust port 630 communicating with the first interface 610 and the second interface 620 respectively. A pipeline is connected between the exhaust outlet 415 and the first interface 610, and a pipeline is connected between the second exhaust port 350 and the second interface 620. In this way, whether it is overpressure or pressure relief after gas injection is completed, exhaust can be performed through the exhaust port 630 on the exhaust member 600.

[0041] When making sparkling water with a sparkling water machine, the gas cylinder interface 210 of the gas cylinder connector 200 is connected to a high-pressure gas cylinder, and the water bottle interface 310 of the water bottle connector 300 is connected to a water-filled water bottle. By pressing down the gas cylinder thimble 240 with the pressing plate 510, the gas cylinder thimble 240 triggers the inflation valve on the gas cylinder to open it. At this time, the free end of the pressing plate 510 rotates downward, the end of the pressing block 520 close to the pressing plate 510 rotates downward, and the end close to the exhaust thimble 430 rotates upward. The first spring 440 pushes the valve core 420 to block the valve port, and the exhaust valve 400 closes. The high-pressure gas in the gas cylinder enters the injection pipe 340 through the pipeline and is injected into the water in the water bottle through the injection pipe 340 to complete the production of sparkling water. After the production of sparkling water is completed, the pressing plate 510 is released. The pressing plate 510 rotates upward under the action of the second spring 511. The free end of the pressing plate 510 pushes the end of the pressing plate 510 close to the pressing plate 510 to rotate upward, and the end close to the exhaust thimble 430 rotates downward, causing the pressing block 520 to press down the exhaust thimble 430. The exhaust thimble 430 overcomes the elastic force of the first spring 440 to push the valve core 420 to move downward to open the valve port, and the exhaust valve 400 opens. In this way, the excess high-pressure gas in the gas cylinder can be discharged through the exhaust valve 400.

[0042] Therefore, when pressing down the pressing plate 510 in this application, the exhaust valve 400 automatically closes, and when releasing the pressing plate 510, the exhaust valve 400 automatically opens. The exhaust valve 400 does not require manual operation, which is convenient for operation. Moreover, the force for the exhaust ejector pin 430 to push the valve core 420 to open comes from the elastic force of the second spring 511, and at the same time, the first spring 440 can provide an elastic force to prevent the valve core 420 from opening, which is convenient for controlling the opening degree of the exhaust valve 400, thereby facilitating the control of the exhaust speed of the exhaust valve 400 and solving the problem of water backflow from the water bottle during exhaust.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
