Description

Technical Field

[0001] This utility model relates to the field of carbonated water preparation, and in particular to a carbonated water preparation system with enhanced solubility. Background Technology

[0002] Carbonated water is water infused with carbon dioxide. The principle is that carbon dioxide dissolves in water under pressure, and bubbles form when the pressure is released. Carbonated water replenishes water and minerals, provides energy, refreshes the mind, relieves heat, promotes digestion, and has antibacterial and bacteriostatic effects, making it popular. Existing carbonated water preparation systems typically use a booster pump to pressurize pure water at the inlet and deliver it to a jetting device. Carbon dioxide gas from a carbon dioxide storage tank is then delivered to the jetting device via a pressure regulating valve. After the carbon dioxide and pure water undergo their first gas-liquid mixture in the jetting device, they are then transferred to a gas-liquid mixing tank for a second gas-liquid mixture, forming carbonated water, which is finally output from the carbonated water outlet. The drawback of this structure is that carbon dioxide and pure water only undergo two gas-liquid mixtures, resulting in poor carbon dioxide dissolution in pure water and a low concentration of carbonated water, leading to a less desirable taste. Therefore, some researchers have improved the carbon dioxide dissolution capacity by connecting more gas-liquid mixing tanks in series, but this increases the equipment manufacturing cost. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a carbonated water preparation system with enhanced solubility, which has high solubility in carbon dioxide and pure water, good dissolving ability, high concentration of carbonated water produced, and low equipment manufacturing cost.

[0004] The technical solution of this utility model for a carbonated water preparation system with enhanced dissolving power is as follows: It includes a water inlet and a carbon dioxide storage tank. The water inlet is connected to a booster pump, which is connected to a jetting device. The jetting device is equipped with a water inlet connector, an air inlet connector, and a water outlet connector. The booster pump is connected to the water inlet connector. The carbon dioxide storage tank is connected to a pressure regulating valve, which is connected to an air inlet valve. The air inlet valve is connected to the air inlet connector of the jetting device. The water outlet connector of the jetting device is connected to the inlet of a gas-liquid mixing tank. The outlet of the gas-liquid mixing tank is connected to a tee connector. One end of the tee connector is connected to the carbonated water outlet, and the other end is connected to the inlet of the carbonated water storage device. The outlet of the carbonated water storage device is connected to the booster pump.

[0005] Furthermore, a pressure stabilizing valve and a first control valve are connected between the water inlet and the booster pump.

[0006] Furthermore, an airflow control valve is connected between the air intake valve and the air intake connector of the jet device.

[0007] Furthermore, a water outlet valve is connected between the tee connector and the carbonated water outlet.

[0008] Furthermore, the three-way connector is connected to a first check valve and a second control valve between itself and the carbonated water storage device.

[0009] Furthermore, a second check valve and a third control valve are provided between the carbonated water storage device and the booster pump.

[0010] Furthermore, the carbonated water storage device is a water tank or a pressure storage tank.

[0011] Furthermore, the carbonated water storage device is connected to a pH sensor.

[0012] The beneficial effects of this novel carbonated water preparation system with enhanced solubility are: 1. By connecting a three-way connector to the outlet of the gas-liquid mixing tank, and then connecting the three-way connector to the carbonated water storage device, the carbonated water storage device is connected to the booster pump through the third control valve and the second check valve to form a loop structure, so that the carbonated water can be circulated and mixed with gas and liquid multiple times until the required pH value is reached, so that carbon dioxide and water can be fully dissolved, ensuring the taste of carbonated water. Second, when people are not using carbonated water, the carbonated water storage device can store the pre-made carbonated water. When people need to drink it, the carbonated water in the storage device is finally mixed with gas and liquid for the last time and then sent out from the carbonated water outlet, reducing the time people wait for the carbonated water to be prepared.

Detailed Implementation

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0016] This utility model relates to a carbonated water preparation system with enhanced solubility, such as... Figure 1As shown, the device includes an inlet 1 and a carbon dioxide storage tank 2. The inlet 1 is connected to a booster pump 3, which is connected to a jetting device 4. The jetting device 4 is equipped with an inlet connector 5, an air inlet connector 6, and an outlet connector 7. The booster pump 3 is connected to the inlet connector 5. The carbon dioxide storage tank 2 is connected to a pressure regulating valve 8, which is connected to an air inlet valve 14. The air inlet valve 14 is connected to the air inlet connector 6 of the jetting device 4. The outlet connector 7 of the jetting device 4 is connected to the inlet of a gas-liquid mixing tank 9. The outlet of the gas-liquid mixing tank 9 is connected to a carbonated water outlet 10. The outlet of the gas-liquid mixing tank 9 is connected to a three-way connector 11. One end of the three-way connector 11 is connected to the carbonated water outlet 10, and the other end of the three-way connector 11 is connected to the inlet of a carbonated water storage device 21. The outlet of the carbonated water storage device 21 is connected to the booster pump 3.

[0017] Furthermore, a pressure stabilizing valve 12 and a first control valve 13 are connected between the water inlet 1 and the booster pump 3. The pressure stabilizing valve 12 can stabilize the pressure of the pure water delivered by the water purification equipment or faucet, reducing fluctuations. The first control valve 13 can be a solenoid valve, which facilitates the controller to open or close it.

[0018] Furthermore, an airflow control valve 15 is connected between the air intake valve 14 and the air intake connector 6 of the jet device 4. With the airflow control valve 15, the amount of carbon dioxide entering the system can be adjusted as needed. The airflow control valve 15 can be a solenoid valve, which facilitates the controller in adjusting the airflow control valve 15.

[0019] Furthermore, a water outlet valve 16 is connected between the three-way connector 11 and the carbonated water outlet 10. The water outlet valve 16 can be a solenoid valve, which facilitates the controller to open or close it.

[0020] Furthermore, a first check valve 17 and a second control valve 18 are connected between the three-way connector 11 and the carbonated water storage device 21. The second control valve 18 can be a solenoid valve, which facilitates the controller to open or close it. When the second control valve 18 is opened, the carbonated water produced after the second gas-liquid mixing in the gas-liquid mixing tank 9 enters the carbonated water storage device 21 through the first check valve 17 and the second control valve 18. The first check valve 17 can prevent the carbonated water in the carbonated water storage device 21 from flowing back.

[0021] Furthermore, a second check valve 19 and a third control valve 20 are provided between the carbonated water storage device 21 and the booster pump 3. The third control valve 20 can be a solenoid valve, which facilitates the controller to open or close it. When the third control valve 20 is opened, the carbonated water in the carbonated water storage device 21 enters the booster pump 3 through the third control valve 20 and the second check valve 19 to be pressurized. The second check valve 19 can prevent carbonated water from flowing back into the carbonated water storage device 21.

[0022] Furthermore, the carbonated water storage device 21 can be a water tank or a pressurized water storage tank. When the carbonated water storage device 21 is a water tank, a water level sensor can be installed in the water tank (the specific structure of the water level sensor is existing technology, which can sense the water level; when the water level reaches a specified height, it indicates that the water tank is full of carbonated water). When the carbonated water storage device 21 is a pressurized water storage tank, a pressure sensor can be installed in the pressurized water storage tank (the specific structure of the pressure sensor is existing technology; when the pressure reaches a specified pressure, it indicates that the pressurized water storage tank is full of carbonated water).

[0023] Furthermore, the carbonated water storage device 21 is connected to a pH sensor 22. The pH value of the carbonated water in the carbonated water storage device 21 can be detected by the pH sensor 22.

[0024] This utility model discloses a carbonated water preparation system with enhanced solubility. The first control valve 13, air inlet valve 14, airflow control valve 15, water outlet valve 16, second control valve 18, and third control valve 20 can all be solenoid valves. These solenoid valves are connected to a controller (the specific structure and setting principle of the controller are existing technologies). The controller can control the opening and closing of the solenoid valves. When preparing carbonated water, the first control valve 13 at the inlet 1 (which can be connected to a water purifier or tap), the air inlet valve 14 of the carbon dioxide storage tank 2, and the second control valve 18 are opened, while the water outlet valve 16 and the third control valve 20 are closed. Pure water enters the booster pump 3 through the inlet 1 for pressurization. The pressurized pure water is then transported to the jet device 4 through the inlet connector 5. (A Venturi jet injector is installed in the jet device 4; its specific structure is existing technology, and can be referred to in CN217676925U for the structure of a Venturi jet injector in the jet cavity). Carbon dioxide in carbon dioxide storage tank 2 is transported to jet device 4 via pressure regulating valve 8, air inlet valve 14, airflow control valve 15, and air inlet connector 6. In jet device 4, pure water and carbon dioxide undergo the first gas-liquid mixing, and are then transported from water outlet connector 7 to gas-liquid mixing tank 9 (gas-liquid mixing tank 9 is equipped with a microfiltration membrane or ultrafiltration membrane and a flow limiting plate; its specific structure is existing technology, and can be referred to in CN217676925U for the structure of a microporous shearing device and a flow limiting plate in the gas-liquid mixing cavity). A second gas-liquid mixing takes place in gas-liquid mixing tank 9, and then the mixture is transported through the first single... The carbonated water is supplied to the carbonated water storage device 21 via valve 17 and the second control valve 18. If the pH sensor 22 detects that the carbonated water in the carbonated water storage device 21 has not reached the specified pH value (the carbonated water concentration can be set as needed, and can be set via the controller; the specific setting principle of the controller is existing technology), the third control valve 20 can be opened and the first control valve 13 can be closed to stop the flow of pure water. At this time, the carbonated water in the carbonated water storage device 21 re-enters the jet device 4 via the third control valve 20, the second check valve 19, the booster pump 3, and the inlet connector 5. Simultaneously, the carbon dioxide storage tank 2 continues to supply carbon dioxide, which continues to undergo a third gas-liquid mixing with the carbonated water, and then undergoes a second gas-liquid mixing via the gas-liquid mixing tank 9. The mixture undergoes four gas-liquid mixing cycles and enters the carbonated water storage device 21. If the specified pH value is not reached, the cycle continues until the specified pH value is reached. At this point, the carbonated water is stored in the carbonated water storage device 21, and the controller closes all solenoid valves. When people want to drink carbonated water, they open the carbonated water outlet 10. The controller controls the third control valve 20, the air inlet valve 14, and the water outlet valve 16 to open, while the first control valve 13 and the second control valve 18 remain closed. At this time, the carbonated water in the carbonated water storage device 21 enters the jet device 4 via the booster pump 3 and mixes with the carbon dioxide from the carbon dioxide storage tank 2 again. The mixture is then transported to the gas-liquid mixing tank 9 to complete the final gas-liquid mixing. The carbonated water is then output through the water outlet valve 16 and the carbonated water outlet 10.
