[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. A gas-liquid mixer and a bubble generating device are provided in the high-flux micro-nano bubble generating system of the present invention. Gas and liquid enter the mixing channel from the air inlet and liquid inlet of the gas-liquid mixer respectively, and the first gas-liquid mixing is performed in the gas-liquid mixer, and then inputted from the mixing channel to the small-flux booster pump, which accelerates the discharge speed of the gas-liquid mixed fluid in the gas-liquid mixer, so that the gas-liquid mixer increases the air intake, and the gas-liquid mixed fluid is pumped by the small-flux booster pump in the small-flux booster pump, and the gas-liquid mixing is performed for the second time; and then inputted into the bubble generating device, the gas-liquid mixed fluid is accessed by the gas-liquid access channel, and the gas-liquid mixed fluid enters the bubbler channel through the jet channel of the jet part, and the gas-liquid mixing is performed for the third time. The present invention generates more micro-nano bubbles by multiple gas-liquid mixing, greatly improves the bubble concentration, and the efficiency of micro-nano bubble generation is higher.

[0025] 2. In the bubble generating device, since the cross-sectional area of ​​the jet channel is smaller than the cross-sectional area of ​​the gas-liquid access channel and the diffusion chamber, the pressure of the gas-liquid mixed fluid increases after entering the jet channel, thereby accelerating the flow rate. After reaching the diffusion chamber, the pressure suddenly decreases, forming a negative pressure that further mixes the water and gas together. After entering the bubble generation channel, the cross-sectional area of ​​the bubble generation channel gradually increases, expanding the water-gas mixing volume. Since the gas rises lightly and the water flows downward, the high-speed water impacts the gas, forming a large number of bubbles instantly. The present invention first accelerates the flow rate to mix the water and gas violently, and then expands the water-gas mixing volume to allow the high-speed water to impact the gas to generate bubbles, thereby generating more micro-nano bubbles with higher efficiency.

[0026] 3. A shunt pipe and a shutoff valve are also provided in the high-flux micro-nano bubble generating system of the present invention. The two cooperate, and the shutoff valve can reduce the water flow entering the liquid inlet to a certain extent (the rest of the water is transported from the shunt pipe to the bubble generator), ensuring that the pipeline behind the shutoff valve will not be completely filled with water, which is conducive to the gas entering the gas-liquid mixer from the gas inlet to form a gas-liquid mixed fluid, thereby improving the efficiency of the first gas-liquid mixing; the small-flux gas-liquid mixed fluid generated by the small-flux booster pump is combined with the non-bubble water flowing out of the shunt pipe to ensure a large flow of bubble water, and finally form a large flow of micro-nano bubble water with a high bubble concentration in the bubble generator. A small-flux booster pump is used to effectively reduce costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The following will be combined with the embodiments and drawings to clearly and completely describe the concept, specific structure and technical effects of the present invention, so as to fully understand the purpose, scheme and effect of the present invention. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other without conflict. The same reference numerals used throughout the drawings indicate the same or similar parts.

[0052] It should be noted that, unless otherwise specified, when a feature is referred to as being "fixed" or "connected" to another feature, it may be directly fixed or connected to the other feature, or it may be indirectly fixed or connected to the other feature. In addition, the descriptions of up, down, left, right, etc. used in the present invention are only relative to the relative positional relationship of the components of the present invention in the drawings.

[0053] Reference Figures 1 to 15 A large-flux micro-nano bubble generating system comprises a gas-liquid mixer 1, a small-flux booster pump 2, a bubble generating device 3 and a diverter pipe 5.

[0054] Among them, Figure 2 and Figure 3 As shown, the gas-liquid mixer 1 includes an air inlet 11, a liquid inlet 12 and a mixing channel 13, one end of the mixing channel 13 connects the air inlet 11 and the liquid inlet 12, and the other end is a first gas-liquid outlet 131, the liquid inlet 12 is connected to the liquid supply pipe and a shut-off valve 43 is provided between the two. The small flux booster pump 2 is connected to the first gas-liquid outlet 131. The air inlet 11 is used to input gas (such as air), the liquid inlet 12 is used to input liquid (such as water), and the mixing channel 13 is used to mix the input gas and liquid, which is the first mixing, and the mixed gas-liquid mixed fluid is discharged from the first gas-liquid outlet 131 to the small flux booster pump 2, which extracts and pumps it to the bubbling device, and the gas and liquid are drawn into the pump and can be discharged from the pump, and undergo a second gas-liquid mixing. Among them, the small flux booster pump 2 can be a booster pump. In one embodiment, the gas-liquid mixer 1 is a venturi ejector, and the preliminary mixing of gas and liquid is completed by the venturi ejector. Of course, the present invention also discloses other embodiments of the gas-liquid mixer 1, which will be described in detail below.

[0055] Among them, Figures 4 to 15 As shown, the bubble generating device 3 includes a jet element 31 and a bubbler 32 .

[0056] like Figure 4 and Figure 5As shown, the jet component 31 is provided with a gas-liquid access channel 311, a jet channel 312 and a diffusion chamber 313 connected in sequence, and the gas-liquid access channel 311 is provided with a first gas-liquid inlet 3111 connected to the small flux booster pump 2; the cross-sectional area of ​​the jet channel 312 is smaller than the cross-sectional areas of the gas-liquid access channel 311 and the diffusion chamber 313. The gas-liquid mixed fluid comes out of the small flux booster pump 2 and is input into the first gas-liquid inlet 3111, and passes through the gas-liquid access channel 311, the jet channel 312 and the diffusion chamber 313 in sequence. Since the cross-sectional area of ​​the jet channel 312 is smaller than the cross-sectional area of ​​the gas-liquid access channel 311, after entering the jet channel 312, the pressure will suddenly increase, thereby accelerating the speed of the flow in the jet channel 312, increasing the impact force of the water flow, and facilitating the generation of bubbles later. After entering the diffusion chamber 313 from the jet channel 312, the gas is ejected quickly. Since the cross-sectional area of ​​the jet channel 312 is smaller than the cross-sectional area of ​​the diffusion chamber 313, the pressure suddenly decreases, thereby forming a negative pressure at the outlet of the jet channel 312, causing the gas to further dissolve in the water. In one embodiment, the cross-sectional area of ​​the diffusion chamber 313 is larger than the cross-sectional area of ​​the gas-liquid access channel 311, thereby increasing the pressure difference and increasing the amount of bubbles dissolved in the water.

[0057] Among them, one end of the shunt tube 5 is connected to the liquid supply pipe 41 and the connection is located in front of the shut-off valve 43, and the other end is connected to the first gas-liquid inlet 3111; wherein, the flow rate of the shunt tube 5 is greater than the flow rate of the small-flux booster pump 2. On the one hand, the small-flux booster pump 2 is used to increase the small-flux gas-liquid mixed fluid, and on the other hand, the shunt tube 5 is used to access more flow, so that the flow rate of the micro-nano bubble water finally generated is large enough and the concentration of micro-nano bubbles is high.

[0058] Based on the above structure, the present invention generates more micro-nano bubbles through multiple gas-liquid mixing, greatly improves the bubble concentration, and has a higher efficiency in generating micro-nano bubbles. In addition, a small-flow gas-liquid mixed fluid generated by a small-flux booster pump 2 is used in combination with non-bubble water flowing out of the diversion pipe 5, thereby ensuring a large flow of bubble water and ultimately forming micro-nano bubble water with a large flow and a high bubble concentration in the bubble generator.

[0059] In one embodiment, the flow rate of the shunt tube 5 is greater than 80% of the total flow rate of the bubble generating device 3. Since the flux of the small-flux booster pump 23 is small, the shunt tube 5 requires a larger flow rate to meet the usage demand. After many tests and adjustments, the inventor confirmed that when the flow rate of the shunt tube 5 accounts for more than 80% of the total flow rate of the liquid inlet pipe, it can achieve better results, which can ensure that the flow rate of the micro-nano bubble water is large and the bubble concentration of the bubble water is high.

[0060] like Figures 5 to 11As shown, the bubbler 32 includes at least one bubble channel 3211, one end of the bubble channel 3211 is a second gas-liquid inlet 32111, and the other end is a second gas-liquid outlet 32112. The second gas-liquid inlet 32111 is connected to the diffusion chamber 313, and the cross-sectional area of ​​the bubble channel 3211 gradually increases from the second gas-liquid inlet 32111 to the second gas-liquid outlet 32112. The gas-liquid mixed fluid coming out of the diffusion chamber 313 enters the bubble channel 3211 from the second gas-liquid inlet 32111. Since the cross-sectional area of ​​the bubble channel 3211 gradually increases from the second gas-liquid inlet 32111 to the second gas-liquid outlet 32112, the gas-water mixed volume is expanded, the pressure gradually decreases, and the gas dissolved in the water becomes bubbles. With the high-speed impact of the water flow on the gas, a large number of micro-nano bubbles are instantly formed and discharged from the second gas-liquid outlet 32112. This is the third mixing of gas and liquid.

[0061] In addition, generally, when in use, the bubble generating device 3 is vertical, the jet element 31 is at the top, and the bubbler 32 is at the bottom, because the gas rises lightly, the water flow impacts downward, and the high-speed water impacts the gas, and the two are violently mixed, thereby forming a large number of micro-nano bubbles instantly. In one embodiment, the bubble channel 3211 is conical. The bubble channel 3211 can be only one, or there can be multiple bubble channels and all connected to the diffusion chamber 313.

[0062] Specifically, Figure 2 and Figure 3 As shown, the liquid inlet channel 12 includes a liquid inlet section 121 and a first jet section 122 connected to the liquid inlet section 121. The liquid inlet section 121 is arranged with equal cross-sections and one end is a liquid inlet 1211. The first jet section 122 is arranged with equal cross-sections and one end is a liquid outlet 1222 connected to the mixing channel 13. The cross-sectional area of ​​the liquid inlet 1211 is greater than the cross-sectional area of ​​the liquid outlet 1222. Liquid is input into the liquid inlet 1211 and discharged into the mixing channel 13 from the liquid outlet 1222. Since the cross-sectional area of ​​the liquid inlet section 121 is greater than the cross-sectional area of ​​the liquid outlet 1222, the flow rate of the liquid is accelerated when passing through the jet section, so that the liquid can quickly rush into the mixing channel 13, and violently mix and dissolve with the gas in the mixing channel 13, which is conducive to the generation of micro-nano bubbles. In one embodiment, the connection between the liquid inlet section 121 and the jet section is arranged in a conical transition.

[0063] Specifically, Figure 2 and Figure 3As shown, the mixing channel 13 includes a mixing section 132 and a second jet section 133. The mixing section 132 is connected to the air inlet 11 and the liquid inlet 12, and the first gas-liquid outlet 131 is provided at the second jet section 133. The gas and liquid input are mixed for the first time in the mixing section 132, and then enter the second jet section 133 after mixing. After passing through the second jet section 133, the gas and liquid are discharged from the first gas-liquid outlet 131 to the small-flux booster pump 2. Among them, the mixing section 132 and the second jet section 133 are set with equal cross-sections, that is, the two can be pipe sections, and the cross-sectional area of ​​the mixing section 132 is larger than the cross-sectional area of ​​the liquid outlet 1222. After the liquid enters the mixing section 132, the space suddenly increases, thereby generating suction, accelerating the suction of the gas and liquid in the air inlet 11 and the liquid inlet 12, and further intensifying the mixing of gas and liquid. The cross-sectional area of ​​the first gas-liquid outlet 131 is larger than the cross-sectional area of ​​the liquid inlet 1211 , that is, the outlet flow rate is larger than the inlet flow rate, and gas is naturally sucked in from the air inlet 11 .

[0064] Preferably, if Figure 1 As shown, the present high-flux micro-nano bubble generating system further comprises a liquid supply device connected to the liquid inlet 12, the liquid supply device comprises a liquid supply pipe 41 and a first control valve 42 for controlling the on-off of the liquid supply pipe 41, the liquid supply pipe 41 can be connected to a faucet or other water source, the first control valve 42 can be a solenoid valve, and a controller can be used to automatically control the channel. More preferably, a pressure stabilizing valve is also provided on the liquid supply pipe 41.

[0065] Likewise, if Figure 1 As shown, the present high-throughput micro-nano bubble generating system also includes an air supply device 5 connected to the air inlet 11, and the air supply device 5 includes an air supply pipe 51 and a second control valve 52 for controlling the on-off of the air supply pipe 51 and a check valve 53 arranged on the air supply pipe 51. The second control valve 52 can be a solenoid valve, and the channel can be automatically controlled by a controller. More preferably, an air filter device and / or a flow regulating valve are also provided on the air supply pipe 51. The air filter device can filter the air entering the gas-liquid mixer 1, and filter the dust and bacteria in the air. The check valve can prevent the pressure in the gas-liquid mixer 1 from being too high, causing the liquid in the gas-liquid mixer 1 to overflow from the air supply pipe 51. The flow regulating valve can control the flow rate of the gas entering the air supply pipe 51, and different flow rates can be selected according to the specific usage.

[0066] Specifically, Figure 5 and Figure 8As shown, the bubbler 32 also includes a first expansion tank 3212 connected to the second gas-liquid inlet 32111, the first expansion tank 3212 is in communication with the second gas-liquid inlet 32111, and an opening is provided at one end of the first expansion tank 3212 away from the second gas-liquid inlet 32111. The provision of the first expansion tank 3212 can increase the water-gas mixing volume, and can also store part of the gas that is not dissolved in water, so that the cavity can accommodate more gas, which is convenient for generating more bubbles. The gas-liquid mixed fluid enters the first expansion tank 3212 from the diffusion chamber 313, and impacts the tank wall of the first expansion tank 3212, so that the gas and liquid are mixed more violently, thereby increasing the number of nano-micro bubbles.

[0067] Preferably, if Figure 5 , Figure 8 and Fig. 9 As shown, the groove wall of the first expansion groove 3212 is provided with a protruding structure 3213 protruding toward the opening. After the bubbles enter the first expansion groove 3212, they impact the protruding structure 3213, and the gas-liquid and water in the gas-liquid mixed fluid are further mixed to generate more bubbles. Specifically, the protruding structure 3213 is sheet-shaped and / or ring-shaped. In one embodiment, the protruding structure 3213 is ring-shaped and sheet-shaped. The ring-shaped protruding structure 3213 is located in the middle, and several sheet-shaped protruding structures 3213 are located on the outside of the ring-shaped protruding structure 3213 and are radially divided into several blocks, and each block is provided with a bubbling channel 3211.

[0068] Furthermore, if Figure 5 , Figure 8 and Fig. 9 As shown, a second expansion groove 3214 connected to the first expansion groove 3212 is further provided on the groove wall of the first expansion groove 3212. The second expansion groove 3214 further increases the gas-liquid mixing volume, which can increase the water-gas mixing volume, and can also store part of the gas that is not dissolved in water, so that the cavity can accommodate more gas, which is convenient for generating more bubbles.

[0069] Among them, Figure 4 and Figure 5 As shown, the jet component 31 is threadedly connected with the bubbler 32. Specifically, the jet component 31 is provided with a first thread segment 314, and an external thread is provided on the first thread segment 314. The bubbler 32 is provided with an internal thread, and the internal thread can be threadedly connected with the first thread segment 314, so as to realize the connection between the jet component 31 and the bubbler 32. In addition, a sealing ring is also provided between the jet component 31 and the bubbler 32 to ensure that there is no leakage at the connection between the two.

[0070] In one embodiment, Figure 4 As shown, the bubbler 32 has only one bubbler 321 .

[0071] In addition, the bubbler 32 has other configurations, such as Figures 10 to 15 As shown, the bubbler 32 includes a plurality of bubbler parts 321 connected in sequence, each of which is provided with the bubbler channel 3211; the second gas-liquid inlet 32111 of the bubbler part 321 at one end is connected to the diffusion chamber 313 of the jet part 31; in two adjacent bubbler parts 321, the second gas-liquid outlet 32112 of the bubbler part 321 close to the jet part 31 is connected to the second gas-liquid inlet 32111 of the bubbler part 321 away from the jet part 31. By increasing the number of bubbler parts 321, the content and efficiency of the micro-nano bubbles in the gas-liquid mixed fluid discharged at the end can be improved. Accordingly, each bubbler part 321 is provided with a first expansion groove 3212, a second expansion groove 3214, and a protruding structure 3213.

[0072] like Fig.10 As shown, two adjacent foaming parts 321 are threadedly connected.

[0073] like Figures 7 to 11 As shown, the bubbler 321 can be divided into two categories according to its specific position, namely, a connecting bubbler 3201 and a terminal bubbler 3202. One end of the connecting bubbler 3201 is provided with an internal thread, and the other end is provided with a second thread segment 3216. The second thread segment 3216 is provided with an external thread. The internal thread can be connected to the first thread segment 314 of the jet element 31, and can also be connected to the second thread segment 3216 of another bubbler 321. The terminal bubbler 3202 is only provided with an internal thread, but no external thread segment, and is connected to the second thread segment 3216 of the previous bubbler 321 through the internal thread.

[0074] In one embodiment, Fig.10 As shown, the bubbler 32 includes two bubble generating parts 321 , and the structure of the bubble generating device 3 is sequentially a jetting part 31 , a connecting bubble generating part 3201 and a terminal bubble generating part 3202 .

[0075] In another embodiment, the bubbler 32 includes three bubbler parts 321, and the structure of the micro-nano bubble generating device 3 is sequentially a jet part 31, a connecting bubbler part 3201, a connecting bubbler part 3201 and a terminal bubbler part 3202. Similarly, the number of bubbler parts 321 in the bubbler 32 can be more, and except for one terminal bubbler part 3202, the rest are connecting bubbler parts 3201.

[0076] In a specific implementation, it may be necessary to input the prepared water rich in micro-nano bubbles into a cleaning device. Therefore, it is necessary to connect the bubble generating device 3 to the cleaning device for convenience, such as Figures 12 to 15As shown, the bubble generating device 3 also includes a gas-liquid outlet joint 33, which is provided with a gas-liquid collecting chamber 331 and a terminal connecting portion 332 for connecting to a water outlet terminal, and the gas-liquid collecting chamber 331 is connected to the second gas-liquid outlet 32112.
