DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] As shown in FIG. 1 through FIG. 4, the present invention discloses a sparkling water maker capable of automatically controlling gas inflow, comprising a gas cylinder 1, a gas cylinder connector 2 mounted on the gas cylinder 1, a bottle 3, and a bottle connector 4 mounted on the bottle 3. The bottle connector 4 is provided with a gas injection tube 17 extending downward to be inserted in a solution in the bottle 3. A gas guide tube is connected between the gas cylinder connector 2 and the bottle connector 4. The compressed gas in the gas cylinder 1 is delivered to the bottle 3 through the gas guide tube by pressing an ejector pin 16 disposed above the mouth of the gas cylinder 1. The gas guide tube includes a first gas guide tube 5 connected to the gas cylinder connector 2 and a second gas guide tube 6 connected to the bottle connector 4. A valve 7 is connected between the first gas guide tube 5 and the second gas guide tube 6. The valve 7 is configured to block a flow passage 18 between the first gas guide tube 5 and the second gas guide tube 6. The valve 7 has a plurality of openings 71, 72, 73, 74 connected to the first gas guide tube 5, the second gas guide tube 6, a first pressure relief tube 8 and a second pressure relief tube 9, respectively. The other end of the first pressure relief tube 8 is connected to the bottle connector 4 and is in communication with the bottle 3. The valve 7 has a chamber 10 therein and a movable member that is movable in the chamber 10. The movable member is configured to block the first gas guide tube 5 or the first pressure relief tube 8. When the pressure at an outlet of the first gas guide tube 5 is greater than the pressure at an outlet of the first pressure relief tube 8, the movable member blocks the first pressure relief tube 8. At this time, the sparkling water maker can perform carbonation. When the gas in the bottle 3 is saturated and the pressure at the outlet of the first pressure relief tube 8 is greater than the pressure at the outlet of the first gas guide tube 5, the movable member blocks the first gas guide tube 5. At this time, the sparkling water maker cannot continue to perform carbonation.

[0022] Furthermore, the valve 7 further includes a first passage 12 and a second passage 13. The first passage 12 and the second passage 13 communicate with the chamber 10. The first passage 12 is connected to the first gas guide tube 5 and the second gas guide tube 6. The second passage 13 is connected to the first pressure relief tube 8. A piston 11 is provided in the chamber 10. Two ends of the piston 11 have different cross-sectional areas, defined as a round block 111 and a round rod 112, respectively. A reducer union is connected between the round rod 112 and the round block 111. The cross-sectional area of the round rod 112 is less than the cross-sectional area of the round block 111. The round rod 112 is close to the first gas guide tube 5. The round block 111 is close to the first pressure relief tube 8. The piston 11 is configured to block the first passage 12 or the second passage 13. When the pressure in the first passage 12 is greater than the pressure in the second passage 13, the piston 11 blocks the second passage 13 under pressure; when the pressure in the second passage 13 is greater than the pressure in the first passage 12, the piston 11 blocks the first passage 12 under pressure.

[0023] Furthermore, one end of the second pressure relief tube 9 is connected to the second passage 13, and the other end of the second pressure relief tube 9 is connected to a pressure relief valve 14. When the pressure in the second pressure relief tube 9 is greater than the preset pressure of the pressure relief valve 14, the pressure relief valve 14 is opened to exhaust the gas to the outside of the sparkling water maker.

[0024] In order to maintain the airtightness, a sealing block 113 is provided at the end of the round rod 112, and sealing rings 114 are provided on the round rod 112 and the round block 111. The sealing rings 114 are in interference fit with the inner wall of the chamber 10.

[0025] A compression spring 15 is provided in the chamber 10. Two ends of the compression spring 15 abut against the round block 111 and the end face of the chamber 10 close to the first gas guide tube 5, respectively. In the initial state, the compression spring 15 drives the piston 11 to move toward the second gas guide tube 6.

[0026] In this embodiment, the gas pressure of the carbon dioxide gas in the gas cylinder 1 is about 0.6 MPa, and the saturation pressure of the bottle 3 is 6 bar. When the gas valve used for controlling the carbon dioxide gas is opened, the carbon dioxide gas pushes the piston 11 rightward and flows into the bottle 3 for performing carbonation, and the gas enters the end having the round block 111 of the piston 11 through the bottle 3. Using the different cross-sectional areas of the two ends of the piston 11, when the when the pressure in the bottle 3 reaches the required 6 bar, the piston 11 is moved leftward to shut off the gas, so as to keep the pressure in the bottle 3 at the required 6 bar. When the gas is released, the pressure relief valve opens to exhaust the excess gas in the bottle 3, so that the carbon dioxide gas is fully utilized, there will be no unnecessary waste, and the gas pressure in the bottle 3 is always maintained at about 6 bar. It is safer for use.
