[0030] Please see Figures 1 to 10A microbubble generator includes a generator body 100, the generator body 100 including a housing 1 and a bubble generating assembly 2 disposed within the housing 1. The housing 1 is provided with a first cavity 11 for mounting the bubble generating assembly 2, a first inlet 12 for liquid inflow, and a first outlet 13 for liquid outflow. The bubble generating assembly 2 includes a first generating element 21, the first generating element 21 having a first channel 214 for liquid to pass through and for generating microbubbles. The first channel 214 has a diameter a away from the first outlet 13 and a diameter b close to the first outlet 13, the diameter a of the first channel 214 being larger than the diameter b.

[0031] In this invention, the housing 1 is the outer shell of the microbubble generator, used to protect the internal components and provide a closed environment to ensure the stability and safety of the liquid flow path. The first cavity 11 provides the installation space for the bubble generating assembly 2 and constitutes the main space for liquid flow. Further, the bubble generating assembly 2 includes a first generating element 21, which has a first channel 214 for liquid to pass through and generate microbubbles. The first channel 214 has a diameter a away from the first outlet 13 and a diameter b close to the first outlet 13. The diameter a of the first channel 214 is larger than the diameter b, forming a channel that gradually decreases in size from the inlet to the outlet. This causes the liquid to be subjected to gradually increasing pressure when passing through the channel. This pressure can atomize the air contained in the liquid, thereby generating microbubbles. Therefore, the design of the first channel 214 utilizes the principle of fluid dynamics to achieve efficient microbubble generation, effectively improving the ease of use and adaptability of the microbubble generator. It solves the problem that existing microbubble generators need to rely on an external power source to power the water pump, which makes it inconvenient to use the microbubble generator.

[0032] Furthermore, the first generator 21 has an upward-facing second cavity 211 on its upper side, the first channel 214 is located inside the second cavity 211 and penetrates the first generator 21, the first generator 21 has a first groove 212 on its upper side located around the second cavity 211, the first groove 212 has a second channel 2121 for liquid to pass through and for generating microbubbles, the second channel 2121 has a diameter c away from the first outlet 13 and a diameter d close to the first outlet 13, and the diameter c of the second channel 2121 is smaller than the diameter d.

[0033] In this invention, the second cavity 211 is located above the first generator 21 with its opening facing upwards, and the first channel 214 is located inside the second cavity 211, meaning that the first cavity 11 and the second cavity 211 are connected. Liquid entering the first cavity 11 from the first inlet 12 can enter the second cavity 211 and pass through the first channel 214 inside the second cavity 211, thereby generating microbubbles. Furthermore, the first groove 212 is located above the first generator 1 and around the second cavity 212, and the first groove 212 has a second channel 2121 for liquid to pass through and generate microbubbles, providing an additional liquid flow path to further increase the generation of microbubbles. Furthermore, the second channel 2121 has a first outlet 13, and the second channel... The second channel 2121 has a diameter c that is far from the first outlet 13 and a diameter d that is close to the first outlet 13. By designing the diameter c to be smaller than the diameter d, the second channel 2121 forms a channel that gradually expands from the inlet to the outlet. This design can also generate microbubbles using the principle of fluid dynamics. Therefore, by introducing the second channel 2121 into the first generator 21, the liquid can generate microbubbles in two different paths, increasing the amount and diversity of microbubbles generated, and effectively improving the generation efficiency and production effect of microbubbles. Specifically, multiple second channels 2121 can be provided and evenly distributed in the first groove 212. This arrangement can effectively increase the amount and quality of microbubbles generated, while avoiding the malfunction caused by blockage of one channel, thus effectively improving the reliability of the microbubble generator.

[0034] Furthermore, the bubble generating assembly 2 includes a first water-blocking member 22 connected to the first generating member 21 and the housing 1. The first water-blocking member 22 includes a first water-blocking portion 221 connected to the upper side of the first cavity 11 and a second water-blocking portion 222 connected to the first water-blocking portion 221 and the first generating member 21. The upper side of the first water-blocking portion 221 is provided with a plurality of first water-guiding portions 2211 connected to the first cavity 11, so that a first water-guiding hole 22111 is formed between two adjacent first water-guiding portions 2211. The first water-blocking member 22 is provided with a third cavity 224 communicating with the second cavity 211. The side of the second water-blocking portion 222 is provided with a first water inlet hole 225 for liquid to pass through and enter the third cavity 224. The diameter of the first water-blocking portion 221 is smaller than the diameter of the first cavity 11 and larger than the diameter of the second water-blocking portion 222.

[0035] In this invention, a first water-blocking part 22 connected to the first generating element 21 and the housing 1 is designed to further guide the liquid entering the first cavity 11. The first water-blocking part 221 connected to the upper side of the first cavity 11 can prevent the liquid flowing in from the first inlet 13 from directly impacting the first generating element 21, while guiding the liquid into a specific area to ensure uniform distribution of water flow. Furthermore, the upper side of the first water-blocking part 221 is provided with multiple first water-guiding parts 2211 connected to the first cavity 11, so that a first water-guiding hole 2211 is formed between two adjacent first water-guiding parts 2211. When the liquid enters the first cavity 11 from the first inlet 13, it will vertically impact the first water-blocking part 221. Under the obstruction of the first water-blocking part 221, the liquid changes its flow direction towards the first water-blocking part. The water flows around the periphery of the first water guide 2211 and is divided into multiple streams by the obstruction of the first water guide 22111, which flows out from the first water guide hole 22111. This provides a more complex path for the liquid flow and effectively promotes the generation and refinement of bubbles. Specifically, the multiple first water guides 2211 are evenly distributed on the upper side of the first water baffle 221 with the axis of the first water baffle 221 as the axis. This design enables the water flow to initially generate bubbles under the impact force and to evenly disperse them under the obstruction of the multiple first water guide holes 22111, further promoting gas-liquid mixing and effectively improving the generation quality of microbubbles. Furthermore, the diameter of the first water baffle 221 is smaller than the diameter of the first cavity 11, which means that the liquid flowing out from the first water guide hole 22111 can enter the space between the shell 1 and the second water baffle 222.

[0036] Furthermore, the first water-blocking member 22 is provided with a third cavity 224 communicating with the second cavity 211, and the side of the second water-blocking member 222 is provided with a first water inlet hole 225 for liquid to pass through and flow into the third cavity 224. This design means that liquid can pass through the space between the housing 1 and the second water-blocking member 222 through the first water inlet hole 225 into the third cavity 224, then flow into the second cavity 211, and finally pass through the first channel 214 and generate microbubbles. Therefore, the design of the first water inlet hole 225 and the third cavity 224 ensures that liquid can effectively pass through the first channel 214, thereby generating microbubbles. Specifically, in some embodiments, the first water inlet hole 225 can be provided in multiple and evenly distributed on the side of the second water-blocking member 222. This design can ensure that liquid can flow into the third cavity 224 evenly, optimizing the flow of liquid.

[0037] Furthermore, the bubble generating assembly 2 also includes a filter element 23 connected to the first water-blocking member 22 and the first generating member 21. The filter element 23 completely covers the outside of the first water inlet hole 225 and abuts against the outer side wall of the second water-blocking part 222 and the first groove 212. The inner side of the third cavity 224 is provided with a first mounting part 2241, and the inner side wall of the first groove 212 is provided with a first mating part 2122 that is connected to the first mounting part 2241.

[0038] This invention, by setting a filter element 23 connected to the first water-blocking component 22 and the first generating component 21, and ensuring that the filter element 23 completely covers the outside of the first water inlet 225 and abuts against the outer walls of the second water-blocking part 222 and the first groove 212, ensures that the liquid in the first cavity 11 is filtered by the filter element 23 before entering the first groove 212 and the third cavity 224. Through the effective filtration of the filter element 23, suspended solids, particulate matter, and other impurities in the liquid can be removed, ensuring the purity of the water entering the first groove 212 and the second cavity 211. This not only improves the quality of microbubbles but also extends the service life of the microbubble generator, reduces maintenance frequency, and effectively improves the reliability of the microbubble generator. Furthermore, the inner side of the third cavity is provided with a first mounting part 2241, and the inner wall of the first groove 212 is provided with a first mating part 2122 that mates with the first mounting part 2241. The connection between the first water-blocking component 22 and the first generator 21 and the first mating part 2122 ensures a stable connection between the first water-blocking component 22 and the first generator 21, preventing displacement or detachment under water flow impact. This effectively improves structural stability and integrity, and forms two separate flow paths. One path is for the liquid filtered by the filter element 23 to flow to the first groove 211 located outside the second cavity 211 and pass through the second channel 2121. The other path is for the liquid filtered by the filter element 23 to pass through the first water inlet hole 225 into the third cavity 224 and flow to the second cavity 211 connected to the third cavity 224, and finally pass through the first channel 214 to generate microbubbles. This separation path ensures that the first channel 214 and the second channel 2121 do not interfere with each other, effectively improving the stability of microbubble generation. Specifically, in some embodiments, the filter material of the filter element 23 can be stainless steel mesh, activated carbon filter element, or multi-layer composite filter material to ensure long-term stable filtration effect.

[0039] Furthermore, the bubble generating assembly 2 also includes a second water-blocking member 24 connected to the first generating member 21. The second water-blocking member 24 is provided with a second water outlet 245 for liquid to pass through. The lower side of the first generating member 21 is provided with a fourth cavity 213 into which the second water-blocking member 24 extends. The second water-blocking member 24 is provided with a second extension 241 on the side toward the first water-blocking member 22. The side of the second extension 241 is provided with a second mating part 2411. The side wall of the fourth cavity 213 is provided with a second mounting part 2131 that is mated and connected with the second mating part 2411.

[0040] This invention, by setting a second water-blocking component 24 connected to the first generating component 21, and providing a second water outlet 245 for liquid to pass through the second water-blocking component 24, addresses the issue that the liquid impact force through the first channel 214 and the second channel 2121 is relatively large. If it flows directly out from the first water outlet 13, it is easy to cause a large impact force, leading to safety risks and reducing the user experience. The second water-blocking component 24 can effectively block the liquid from the first channel 214 and the second channel 2121, reduce and disperse the liquid impact force, and promote the further generation of microbubbles, which finally flow out from the second water outlet 245. This effectively improves the quality of the microbubbles and the user experience of the microbubble generator. Furthermore, the lower side of the first generating component 21 is provided with a water outlet 245 for the liquid to pass through. The second water-blocking member 24 extends into the fourth cavity 213, providing installation space for the second water-blocking member 24. This effectively improves the structural compactness and integrity of the microbubble generator and ensures that the water flow can be fully mixed and dispersed within it, promoting gas-liquid contact. Furthermore, by providing a second extension 241 on the side of the second water-blocking member 24 toward the first water-blocking member 22, and providing a second mating part 2411 on the side of the second extension 241, and providing a second mounting part 2131 on the side wall of the fourth cavity 213 that mates with and connects to the second mating part 2411, the second water-blocking member 24 and the first generating member 21 are securely connected, preventing them from shifting or falling off under the impact of water flow, effectively improving the connection stability and reliability between the two.

[0041] Furthermore, the second water-blocking member 24 is also provided with a third extension 242 in the same extension direction as the second extension 241. The second water-blocking member 24 extends into the fourth cavity 213, so that the third extension 242 and the first generating member 21 form a fifth cavity 243, and the second extension 241, the third extension 242 and the first generating member 21 form a sixth cavity 244. The fifth cavity 243 and the sixth cavity 244 are respectively connected to the first channel 214 and the second channel 2121. The third extension 242 is provided with a through hole 2421 connecting the fifth cavity 243 and the sixth cavity 244.

[0042] This invention provides a third extension 242 in the second water-blocking member 24, extending in the same direction as the second extension 241. This allows the third extension 242 and the first generating member 21 to form a fifth cavity 243, and the second extension 241, third extension 242, and the first generating member 21 to form a sixth cavity 244. The fifth cavity 243 and the sixth cavity 244 are respectively connected to the first channel 214 and the second channel 2121. Since the structures of the first channel 214 and the second channel 2121 are different, the sizes of the bubbles they generate are also different. The design of the fifth cavity 243 and the sixth cavity 244 enables… The first channel 214 and the second channel 2121 are effectively separated to prevent them from affecting each other and ensure the quality of microbubble generation. Furthermore, by providing a through hole 2421 in the third extension 242 to connect the fifth cavity 243 and the sixth cavity 244, the different bubbles in the two cavities can be mixed to a certain extent, making the microbubbles in the liquid more uniform and balancing the pressure of the two cavities, which effectively improves the output effect of the microbubble generator. Specifically, in some embodiments, multiple through holes 2421 can be provided and evenly distributed in the third extension 242, which increases the complexity and mixing degree of liquid flow and promotes the distribution and uniformity of bubbles in the liquid.

[0043] Furthermore, the bubble generating assembly 2 also includes a third water-blocking member 25 connected to the housing 1. The third water-blocking member 25 is provided with a plurality of third water outlet holes 251 for liquid to pass through. The diameter of the third water outlet holes 251 is smaller than the diameter of the second water outlet hole 245. The third water-blocking member 25 is located below the second water-blocking member 24. The bubble generating assembly 2 also includes a fourth water-blocking member 26 connected to the housing 1 and provided at the first water outlet 13. The fourth water-blocking member 26 is provided with a plurality of fourth water outlet holes 261 for liquid to pass through. The upper side of the housing 1 is provided with a connecting part 28 connected to an external water channel. The connecting part 28 communicates with the first water inlet 12.

[0044] This invention provides a third water-blocking component 25 connected to the housing 1 on the lower side of the second water-blocking component 24, and provides multiple third water outlets 251 on the third water-blocking component 25, each with a diameter smaller than the second water outlet 245, for liquid to pass through. Through the different diameter water outlets on the second water-blocking component 24 and the third water-blocking component 25, since the third water-blocking component 25 is located below the second water-blocking component 24, the liquid passing through the second water-blocking component 24 will continue to pass through the third water outlets 251 on the third water-blocking component 25, and be dispersed into smaller droplets, which helps to generate finer bubbles, thereby improving the microbubble generation quality of the microbubble generator. Specifically, in some embodiments, the second water outlet 245... 45 are evenly distributed on the third water-blocking component 25. Further, the fourth water-blocking component 26 is connected to the housing 1 and is located at the first water outlet 13. The fourth water-blocking component 26 is provided with multiple fourth water outlet holes 261 for liquid to pass through. This means that the liquid passing through the third water-blocking component 25 will continue to pass through the fourth water outlet holes 261 of the fourth water-blocking component 26, further dispersing the liquid and making the bubbles in the liquid more uniform and fine, effectively improving the microbubble generation quality of the microbubble generator. Furthermore, by providing a connection part 28 on the upper side of the housing 1 to connect with the external water channel, the microbubble generator can be connected to the external water channel, effectively improving the ease of use of the microbubble generator.

[0045] Furthermore, the first water-blocking part 221 is provided with a plurality of second water-guiding holes 2221 evenly on its side, and the second water-blocking part 222 is provided with a plurality of fourth extensions 223 that extend outward and abut against the inner side of the filter element 23 evenly on its side, so that a seventh cavity 227 is formed between the filter element 23 and the second water-blocking part 222, and the seventh cavity 227 is connected to the first groove 212 and the third cavity 224.

[0046] This invention, by uniformly providing a plurality of second water guide holes 2221 on the side of the first water-blocking part 221, allows the liquid passing through the first water guide holes 22111 to form a more complex liquid flow path under the guidance of the second water guide holes 2221, promoting the generation of bubbles. Specifically, in some embodiments, the second water guide holes 2221 are arc-shaped. Furthermore, by uniformly providing a plurality of fourth extensions 223 extending outward and abutting against the inner side of the filter element 23 on the side of the second water-blocking part 222, a gap is formed between the filter element 23 and the second water-blocking part 222. A seventh cavity 227 is formed, which is connected to the first groove 212 and the third cavity 224. This means that the liquid filtered by the filter element 23 can enter the seventh cavity 227. The liquid entering the seventh cavity 227 collides with the second water-blocking part 222, promoting the generation of bubbles and gas-liquid mixing. The seventh cavity 227 provides space for gas-liquid mixing. At the same time, the seventh cavity 227 is connected to the first groove 212 and the third cavity 224, which can divert the liquid to the first groove 212 and the third cavity 224, thereby realizing the process of microbubble generation.

[0047] Further, the housing 1 includes an upper housing 14 and a lower housing 15 connected to the upper housing 14. The first water inlet 12 is located in the upper housing 14, and the first water outlet 13 is located in the lower housing 15. The lower housing 15 has a fifth extension 151 extending inward at one end near the first water outlet 13. The generator body 100 also includes a sealing member 3 connected to the lower housing 15, the upper housing 14, and the first generating member 21. The fourth water-blocking member 26 is connected to the fifth extension 151. The fourth water-blocking member 26 is connected to the lower side of the sealing member 3, and the lower housing 15 and the first generating member 21 are connected to the upper side of the sealing member 3.

[0048] In this invention, the housing 1 is divided into an upper housing 14 and a lower housing 15. This split-connection structure facilitates assembly and maintenance by the user. The first water inlet 12 is located on the upper housing 14, and the first water outlet 13 is located on the lower housing 15. This layout promotes smooth liquid flow and bubble generation. Furthermore, the lower housing 15 has a fifth extension 151 extending inward at the end near the first water outlet 13, which cooperates with the fourth water baffle 26. Further, by providing a connection with the lower housing 15... The sealing element 3, which connects the upper housing 14 and the first generating element 21, prevents liquid from leaking from the connection gap between the first generating element 21 and the housing 1, effectively improving structural stability. Furthermore, the fourth water-blocking element 26 is disposed between the sealing element 3 and the fifth extension 151, so that when assembling the microbubble generator, the sealing element 3 can fix the fourth water-blocking element 26 under the pressure of the upper housing 14, lower housing 15, and first generating element 21, reducing the number of fixing structures and effectively improving the structural compactness of the microbubble generator and reducing production costs.

[0049] A microbubble generating device, including the microbubble generator mentioned above.
