In addition, if terms such as "first", "second", "third" appear, they are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0027] The present application will be further described below in conjunction with the drawings and specific embodiments.

[0028] Embodiment 1: As shown in Figure 1 Fig. 1 is a structural schematic diagram of a water dispenser according to an embodiment of the present application; the water dispenser comprises a body 100, the body 100 is provided with a gas tank 200, a water tank 300 and a mixing chamber 400. The body 100 is also provided with a button 101 and a water outlet 102 for outputting liquid outward, and the water outlet 102 starts to output water when the button 101 is pressed. The body comprises an outer shell, the outer shell forms a containing cavity, the gas tank and the mixing chamber are arranged in the containing cavity, at this time, the water tank can be arranged outside the outer shell, which facilitates water replacement, and at the same time, the gas tank and the mixing chamber are arranged in the containing cavity, so that the user can control the amount of mixed soda according to the demand, and output on demand, without the need to prepare a large amount of soda at one time and cause unnecessary waste.

[0029] The gas tank 200 is filled with CO2, and the gas tank 200 is connected with the mixing chamber 400 through the gas outlet pipeline 201, so that the mixing chamber 400 can be filled with gas. The gas tank 200 is provided with an exhaust valve, and the exhaust valve is connected with the mixing chamber 400 below the lowest liquid level through the gas outlet pipeline 201, so as to ensure the effect of filling gas. In addition, the exhaust valve can be linked with the button 101 to realize the opening and closing function of the gas tank 200.

[0030] The water tank 300 is detachably connected to the machine body 100 through the coupler. The water tank 300 can be taken out alone for use, such as taking water alone or refrigerating to obtain ice water or heating to obtain hot water. The machine body 100 is provided with a filtering device. The filtering device adopts a filter core 500, which can be a combination of one or more of PP cotton, carbon rod, carbon fiber, carbon powder, resin, ultrafiltration, RO membrane, etc. The filter core 500 is arranged in the middle of the water tank 300 and divides the water tank 300 into an upper raw water area and a lower purified water area. The unfiltered raw water is poured into the top of the water tank 300, and under the action of gravity, the raw water is filtered by the filter core 500 and flows to the lower purified water area. The purified water area is connected with the mixing chamber 400 through the water outlet pipeline 301. The water outlet pipeline 301 is also provided with a water pump 302 and a check valve 303. The water pump 302 is used to pump the purified water in the purified water area to the mixing chamber 400. The check valve 303 is a one-way flow valve or a valve that is opened during water inflow and closed after water inflow. Its main function is to prevent gas or water from flowing out of the mixing chamber 400 through the water outlet pipeline 301 during the entire working process, thereby preventing the pressure in the mixing chamber 400 from being released.

[0031] The mixing chamber 400 is provided with a drain port, and the lowest position of the mixing chamber 400 is provided with a drain pipeline 401. The drain port is connected with the water outlet 102 through the drain pipeline 401. The drain pipeline 401 is provided with a drain valve 402. The drain valve 402 is a pressure valve. When the pressure in the drain pipeline 401 reaches a certain value, the drain valve 402 is opened. When the pressure is less than a certain value, the drain valve 402 is closed. After the drain valve 402 is opened, the liquid in the mixing chamber 400 automatically flows to the water outlet 102. The drain valve 402 is linked with the button 101 through the first connecting rod 403. When the button 101 is not pressed, the first connecting rod 403 abuts against the drain valve 402, so that the drain valve 402 is always open, ensuring that there is no pressure in the mixing chamber 400, improving the safety of the equipment, and facilitating the next water inflow of the mixing chamber 400. When the button 101 is pressed to start making bubble water, the first connecting rod 403 no longer acts on the drain valve 402. The drain valve 402 is controlled to be opened or closed by the pressure in the mixing chamber 400. That is, when the mixing chamber 400 is filled with more and more gas, the pressure in the mixing chamber 400 becomes larger and larger, until the set value of the drain valve 402 is reached, and then the drain valve 402 is opened. The bubble water automatically flows to the water outlet 102, realizing pressure drainage.

[0032] The mixing chamber 400 is equipped with a safety valve 404 and a pressure relief pipe 405. The safety valve 404 is positioned above the highest liquid level in the mixing chamber 400, and its pressure resistance is greater than that of the drain valve 402. When the drain pipe 401 becomes blocked, the gas pressure in the mixing chamber 400 gradually increases, exceeding the safety setting of the safety valve 404. At this point, under the pressure, the safety valve 404 automatically opens, releasing the gas through the pressure relief pipe 405 to ensure safe operation of the equipment.

[0033] To further enhance the functionality of the mixing chamber 400, a UV sterilization lamp 406 can be installed inside the mixing chamber 400 to improve drinking water quality; a water level sensor 407 can be installed to detect the water level inside the mixing chamber 400 and limit the amount of sparkling water produced.

[0034] In this embodiment, raw water is added to the water tank 300, filtered by the filter element 500, and then pumped into the mixing chamber 400 by the water pump 302 through the outlet pipe 301. CO2 is stored in the gas tank 200 and is also input into the mixing chamber 400 through the gas outlet pipe 201, thus automatically producing sparkling water in the mixing chamber 400. Because a separate mixing chamber 400 is provided, the amount of raw water and CO2 added can be controlled to achieve quantitative production of sparkling water. After the sparkling water is produced, the drain valve 402 is opened to discharge the sparkling water in the mixing chamber 400 to the outlet 102, which is convenient and quick. In addition, when the gas tank 200 is closed, and only water and no gas enter the mixing chamber 400, the liquid discharged from the outlet 102 is drinking water without bubbles, thus achieving the goal of dispensing both drinking water and sparkling water from a single outlet 102.

[0035] Example 2: Based on the structure in the above examples, the difference is that, as shown in the example... Figure 2 As shown in the figure, a mechanical pressure relief valve 408 is separately provided on the mixing chamber 400 in this example. The mechanical pressure relief valve 408 is located above the highest liquid level in the mixing chamber 400. The mechanical pressure relief valve 408 is linked to the button 101 through the second connecting rod 409. When the button 101 is not pressed, the second connecting rod 409 pushes against the mechanical pressure relief valve 408 to keep it open, and the mixing chamber 400 maintains normal pressure to facilitate the water intake of the mixing chamber 400. When the button 101 is pressed, the second connecting rod 409 moves away from the mechanical pressure relief valve 408 to close it. At this time, the mixing chamber 400 is relatively sealed to ensure that the mixing chamber 400 has the pressure required to produce bubble water.

[0036] In this embodiment, the mechanical pressure relief valve 408 makes it easier for the mixing chamber 400 to receive water under normal pressure. However, it must be noted that the button 101 must be pressed continuously when the mixing chamber 400 is draining water, because if the button 101 is released, the mechanical pressure relief valve 408 will open, and there will be no pressure in the mixing chamber 400, so pressure drainage cannot be achieved.

[0037] Example 3: Based on the structure in the above examples, and different from the direct drinking water mode in the above examples, as shown in Figure 3 In this example, the body 100 is provided with a direct drinking water pipeline 304, and the water outlet pipeline 301 is provided with a water pipeline conversion valve 305. One end of the direct drinking water pipeline 304 is connected with the water pipeline conversion valve 305, and the other end of the direct drinking water pipeline 304 is connected with the water outlet 102. After the raw water in the water tank 300 is filtered, there are two water pipeline options after passing through the water pipeline conversion valve 305. One is through the water outlet pipeline 301 to enter the mixing chamber 400 for making bubble water, and the other is through the direct drinking water pipeline 304 to directly reach the water outlet 102 for direct drinking water. On the basis of the function of making bubble water, the direct drinking water function is added, which is different from the direct drinking water path in Example 1. The direct drinking water in this embodiment does not need to pass through the mixing chamber 400 and is not affected by the residual CO2 in the mixing chamber 400. The direct drinking water coming out of the water outlet 102 is more pure.

[0038] Example 4: Based on the structure in the above examples, the difference is that, as shown in Figure 4 In this example, a drainage structure of the mixing chamber 400 is provided. The drainage pipeline 401 is provided with a drainage pump 410. After the drainage valve 402 is opened, the drainage pump 410 draws the liquid in the mixing chamber 400 to the water outlet 102. The drainage pump 410 is used to draw the liquid in the mixing chamber 400 and discharge it from the water outlet 102. The performance is stable, and the front and rear water outlet speeds are consistent.

[0039] Example 5: Based on the structure in the above examples, the difference is that, as shown in Figure 5 In this example, a drainage structure of the mixing chamber 400 is provided. The height of the drainage outlet is higher than the height of the water outlet 102, and there is a height difference between the drainage outlet and the water outlet 102. The type of the drainage valve 402 is not limited and can be a pressure valve, an electric valve, a manual valve, etc. After the drainage valve 402 is opened, it does not need to rely on other power devices. Under the influence of gravity, the liquid in the mixing chamber 400 can automatically flow out of the water outlet 102.

[0040] Example 6: Based on the structure in the above examples, the difference is the position of the filter element 500, as shown in Figure 6 In this example, the filter element 500 is arranged on the water outlet pipeline 301 between the water tank 300 and the mixing chamber 400. The filter element 500 filters the raw water in the water tank 300 in real time to ensure the health of the drinking water.

[0041] Example 7: Based on the structure in the above examples, the difference is the position of the filter element 500, as shown in Figure 7As shown in the figure, the filter element 500 is arranged at the bottom of the water tank 300, and the outlet of the filter element 500 is connected with the water pump 302 in a coupling mode, and the suction force of the water pump 302 accelerates the filtration of raw water by the filter element 500, so that real-time filtration and real-time drinking are realized.

[0042] The above embodiments are only used for further illustrating the application, and cannot be understood as limiting the protection scope of the application, and some non-essential improvements and adjustments of the application by the technical engineers in the art according to the above content of the application all fall within the protection scope of the application.
