[0002] As people's living standards improve, the popularity of healthy drinks in daily life continues to increase, among which sparkling water is favored by people from all walks of life. The traditional method of preparing sparkling water has some limitations. It is usually necessary to pre-inject carbon dioxide and water into the mixing tank, and then stir it thoroughly to form a uniformly mixed sparkling water. This process not only has a slow preparation speed, but also a long waiting time for customers, which is difficult to meet the needs of modern fast-paced life. In addition, the sparkling water preparation device needs to use a high-pressure resistant closed cavity to pressurize and promote the dissolution of carbon dioxide into the water. However, this method cannot generate sparkling water instantly and there are safety hazards.

[0034] Figure 1 FIG. 2 shows a cross-sectional view of a microbubble generating device according to an embodiment of the present disclosure. Figure 1, the microbubble generating device includes a main body 1 and an annular body 2. The inner cavity of the main body 1 is provided with a liquid inlet channel 11, an air inlet channel 12 and a gas-liquid mixing channel 13. The liquid inlet channel 11 is used to guide the liquid into the interior of the microbubble generating device to mix with the gas. Usually, the liquid inlet channel 11 is connected to an external liquid source, such as water or other solutions. The air inlet channel 12 is used to introduce gas into the interior of the microbubble generating device. Usually, the channel is connected to an external gas source, such as a gas cylinder or an air pump. The gas-liquid mixing channel 13 is a channel for achieving mixing of gas and liquid.

[0035] The air inlet channel 12 is connected to the gas-liquid mixing channel 13 through the annular body 2, the axis of the liquid inlet channel 11 and the axis of the gas-liquid mixing channel 13 are on the same straight line, and the annular body 2 is arranged at the connection between the liquid inlet channel 11 and the gas-liquid mixing channel 13. The air inlet channel 12, the liquid inlet channel 11, the gas-liquid mixing channel 13 and the annular body 2 are arranged in the same housing, which effectively reduces space occupation and manufacturing costs and improves the convenience of maintenance.

[0036] Figure 2 FIG. 2 shows a schematic diagram of the structure of the annular body according to an embodiment of the present disclosure. Figure 2 The ring body 2 is provided with a plurality of raised portions 21 arranged in sequence along the ring contour, and a preset distance is provided between two adjacent raised portions 21, which are used to form a flow opening and cut the bubbles generated when the gas and liquid are mixed. The flow opening on the ring body 2 can reduce the volume of the bubbles generated when the gas and liquid are mixed, thereby increasing the contact area between the gas and the liquid and accelerating the dissolution of the gas in the liquid; the design of the flow opening helps to control the size and distribution of the bubbles, making the generated bubbles smaller and more uniform, helping to improve the stability and uniformity of the microbubbles, thereby improving the taste of the generated bubble water.

[0037] In one embodiment, Figure 2 The annular body 2 includes an outer cylinder 22, an inner cylinder 23 arranged inside the outer cylinder 22, and a top plate 24 connecting the top of the outer cylinder 22 and the top of the inner cylinder 23. The outer cylinder 22, the inner cylinder 23 and the top plate 24 form a receiving cavity for receiving gas and liquid. The structure of the annular body 2 is designed to form a receiving cavity, which provides sufficient contact space for gas and liquid, thereby providing good conditions for the treatment of bubbles and promoting sufficient mixing of gas and liquid.

[0038] like Figure 2, a plurality of raised portions 21 arranged in sequence along the bottom contour of the inner cylinder 23 are provided at the bottom of the inner cylinder 23. The present disclosure does not limit the preset distance between two adjacent raised portions 21. In one embodiment, the preset distance is greater than or equal to 2 mm and less than or equal to 3 mm. The preset distance between the raised portions 21 can effectively limit the size of the bubbles. When the gas-liquid mixture flows between the raised portions 21, it is squeezed and sheared, so that the volume of the bubbles in the gas-liquid mixture is reduced, the contact area between the gas and the liquid is increased, and the efficiency of the gas-liquid mixing is improved.

[0039] like Figure 2 A through hole 25 is provided on the side of the annular body 2. The through hole 25 is connected to the air inlet channel 12 and is used to transfer the gas from the air inlet channel 12 to the accommodating chamber. By connecting the through hole 25 to the air inlet channel 12, the gas can quickly and conveniently enter the accommodating chamber from the air inlet channel 12, thereby achieving uniform mixing of the gas and the liquid.

[0040] In one embodiment, the plane where the bottom of the outer cylinder 22 is located is the same plane as the plane where the tops of the multiple protrusions 21 are located, which effectively prevents gas and liquid from escaping from the gap between the two planes, ensures the sealing of the device, is conducive to the effective treatment of bubbles, and achieves sufficient mixing of gas and liquid.

[0041] In one embodiment, Figure 2 A positioning notch 26 is provided at the bottom of the outer cylinder 22, and a positioning protrusion matching the positioning notch 26 is provided inside the body 1. The positioning protrusion and the positioning notch 26 are used to define the position of the annular body 2 so that the through hole 25 is aligned with the air inlet passage 12. The cooperation between the positioning protrusion and the positioning notch 26 ensures that when the annular body 2 is installed, the through hole 25 is accurately aligned with the air inlet passage 12, avoiding the position offset or misalignment of the through hole 25, thereby ensuring the efficiency and accuracy of gas transmission; the design of the positioning protrusion and the positioning notch 26 simplifies the assembly process, making the alignment of the through hole 25 with the air inlet passage 12 easier and more accurate, which helps to improve production efficiency and reduce assembly costs.

[0042] like Figure 1 The gas-liquid mixing channel 13 includes a first gas-liquid mixing channel 131 and a second gas-liquid mixing channel 132. The first gas-liquid mixing channel 131 and the second gas-liquid mixing channel 132 are both hollow cylindrical structures, and the inner diameter of the first gas-liquid mixing channel 131 is smaller than the inner diameter of the second gas-liquid mixing channel 132.

[0043] The present disclosure does not limit the inner diameter of the first gas-liquid mixing channel 131 and the inner diameter of the second gas-liquid mixing channel 132. In one embodiment, the ratio of the inner diameter of the first gas-liquid mixing channel 131 to the inner diameter of the second gas-liquid mixing channel 132 is greater than or equal to 1 / 3 and less than or equal to 1 / 2. The use of two hollow cylindrical structures with different inner diameters as the gas-liquid mixing channel is intended to utilize the diameter difference effect to produce a flow rate difference to promote the full mixing of gas and liquid. Specifically, due to the relationship between fluid velocity and pipe diameter, a channel with a smaller inner diameter will produce a higher flow rate, while a channel with a larger inner diameter will produce a lower flow rate. Therefore, when the liquid passes through the first gas-liquid mixing channel 131, due to the small inner diameter of the first gas-liquid mixing channel 131, the liquid flow rate is relatively high, which causes the gas to be affected by the high liquid flow rate and thus be subdivided into smaller bubbles; when the gas-liquid mixture passes through the second gas-liquid mixing channel 132, due to the large inner diameter of the second gas-liquid mixing channel 132, the liquid flow rate is relatively low. In this case, the interaction between the gas and the liquid is more sufficient, because the lower flow rate provides more time to achieve the mixing of the gas and the liquid, while preventing the aggregation of bubbles, thereby maintaining the uniformity and stability of the gas-liquid mixture. The first gas-liquid mixing channel 131 and the second gas-liquid mixing channel 132 both adopt a hollow cylindrical structure. By using a hollow cylindrical structure, the inner diameter of the channel remains unchanged, which can avoid the situation where the pressure change or the flow rate change is large, further preventing the aggregation of bubbles, and helping to evenly disperse the gas into the liquid to maintain the uniformity and stability of the gas-liquid mixture.

[0044] The present disclosure does not limit the length of the first gas-liquid mixing channel 131. In one embodiment, the length of the first gas-liquid mixing channel 131 is greater than or equal to 2 mm and less than or equal to 4 mm, which helps to promote the mixing process of gas and liquid in the first gas-liquid mixing channel.

[0045] Figure 3 FIG. 2 shows a schematic diagram of the decomposition structure of the body according to an embodiment of the present disclosure. Figure 3 The body 1 includes a first body 14 and a second body 15, and the first body 14 is threadedly connected to the second body 15. By adopting the threaded connection, the first body 14 and the second body 15 can be easily unscrewed and assembled, which is helpful for repairing and replacing parts; the threaded connection provides a strong sealing performance and can effectively prevent liquid or gas leakage; at the same time, due to the stability of the threaded connection, the device is more stable and reliable during operation.

[0046] The present disclosure also provides a water terminal including the microbubble generating device. The present disclosure does not limit the water terminal, and it can be a water purifier, a water dispenser, a sparkling water dispenser, or other water drinking machines, which can provide a variety of choices for different groups of people to meet different drinking water needs. The water treated by the microbubble generating device is clearer and has a better taste, which can improve people's drinking experience.

[0047] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
