Technical Field

[0001] The invention belongs to the field of water treatment equipment, and in particular relates to a micro-nano bubble generating connector. Background Art

[0002] Micro-nano bubbles refer to bubbles with a diameter ranging from hundreds of nanometers to about ten microns when they occur. These bubbles have physical and chemical properties that conventional bubbles do not have. They have large specific surface area, slow rising speed, self-pressurized dissolution, surface charge, the ability to generate a large number of free radicals, and a high gas solubility rate. They can be well applied in aquaculture, soilless cultivation, fruit and vegetable cleaning, beauty and skin care, water environment management, and sewage treatment. For example, in cleaning equipment, if micro-nano bubble water is output during cleaning, the cleaning effect will be greatly improved. However, the bubble water outlet of the existing micro-nano bubble water generating equipment is difficult to match and connect with the water outlet terminal of the original cleaning equipment, making it difficult to output the generated bubble water to the cleaning equipment for cleaning, or the cleaning equipment needs to be significantly adjusted before it can be used, which is very inconvenient.

[0006] A micro-nano bubble generating connector, comprising:

[0007] A jet component, wherein the jet component is provided with a gas-liquid access channel, a jet channel, and a diffusion chamber connected in sequence, wherein an end of the gas-liquid access channel away from the jet channel is provided with a first gas-liquid inlet for inputting a gas-liquid mixed fluid; and 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; and

[0008] The bubbler includes at least one bubble channel, one end of the bubble channel is a second gas-liquid inlet, and the other end is a gas-liquid outlet, the second gas-liquid inlet is connected to the diffusion chamber, and the cross-sectional area of ​​the bubble channel gradually increases from the second gas-liquid inlet to the gas-liquid outlet; the gas-liquid outlet joint is provided with a gas-liquid collecting chamber and a terminal connecting portion for connecting to a water outlet terminal, the gas-liquid collecting chamber is connected to the gas-liquid outlet.

[0009] As a further improvement to the technical solution of the present invention, the cross-sectional area of ​​the diffusion chamber is larger than the cross-sectional area of ​​the gas-liquid access channel.

[0010] As a further improvement of the technical solution of the present invention, the bubbling channel is conical.

[0011] As a further improvement of the technical solution of the present invention, the bubbler also includes a first expansion tank connected to the second gas-liquid inlet, the first expansion tank is communicated with the second gas-liquid inlet, and an opening is provided at one end of the first expansion tank away from the second gas-liquid inlet.

[0012] As a further improvement to the technical solution of the present invention, the groove wall of the first expansion groove is provided with a protruding structure protruding toward the opening.

[0013] As a further improvement of the technical solution of the present invention, the protruding structure is in the shape of a sheet and / or a ring.

[0014] As a further improvement of the technical solution of the present invention, a second expansion groove communicating with the first expansion groove is further provided on the groove wall of the first expansion groove.

[0015] As a further improvement of the technical solution of the present invention, the jet component is threadedly connected to the bubbler.

[0016] As a further improvement of the technical solution of the present invention, the bubbler includes a plurality of bubblers connected in sequence, and each bubbler is provided with the bubble channel;

[0017] The foaming member at one end is connected to the diffusion chamber of the jet member, and the foaming member at the other end is connected to the gas-liquid outlet joint;

[0018] In two adjacent foaming parts, the gas-liquid outlet of the foaming part close to the jet part is connected to the second gas-liquid inlet of the foaming part far from the jet part.

[0019] As a further improvement to the technical solution of the present invention, two adjacent foaming parts are connected by threads.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The micro-nano bubble generating connector of the present invention is provided with a jet component and a gas-liquid outlet joint. The gas-liquid mixed fluid can be connected to the gas-liquid access channel and connected to the water outlet terminal device (such as the water outlet faucet of the cleaning equipment) through the gas-liquid outlet joint. No additional modification of the cleaning equipment is required, which is more convenient to use.

[0022] 2. The gas-liquid mixed fluid passes through the jet channel of the jet component and then enters the bubbling channel of the bubbling component. 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, which causes the water and gas to be further mixed together; after entering the bubbling channel, the cross-sectional area of ​​the bubbling channel gradually increases, expanding the water-gas mixing volume. Because the gas rises lightly and the water flows downward, the high-speed water flows and impacts the gas, forming a large number of bubbles instantly. The liquid containing a large number of micro-nano bubbles enters the gas-liquid collection chamber and is input into the water outlet terminal device from the terminal connection part, and then can be supplied to the cleaning equipment through the gas-liquid outlet joint with the liquid containing a large number of micro-nano bubbles for cleaning use.

[0023] 3. The present invention first accelerates the flow rate to mix the water and gas vigorously, and then expands the water and gas mixing volume to allow the high-speed water flow to impact the gas to generate bubbles, thereby generating more micro-nano bubbles and higher efficiency.

[0042] 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 and features in the embodiments of this application can be combined with each other unless there is a conflict. The same reference numerals used throughout the drawings indicate the same or similar parts.

[0043] 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 indirectly fixed or connected to the other feature. Furthermore, terms such as "upper," "lower," "left," and "right" used in this disclosure are intended solely to describe the relative positions of the components of the disclosure as shown in the accompanying drawings.

[0044] Reference Figures 1 to 13 A micro-nano bubble generating connector includes a jet component 1, a bubbler 2 and a gas-liquid outlet joint 3.

[0045] Among them, reference Figures 1 to 4The jet element 1 comprises a sequentially connected gas-liquid inlet channel 11, a jet channel 12, and a diffusion chamber 13. A first gas-liquid inlet 111 is provided at the end of the gas-liquid inlet channel 11, distal from the jet channel 12, for inputting a gas-liquid mixed fluid. The cross-sectional area of ​​the jet channel 12 is smaller than that of the gas-liquid inlet channel 11 and the diffusion chamber 13. The gas-liquid mixed fluid enters through the first gas-liquid inlet 111 and sequentially passes through the gas-liquid inlet channel 11, the jet channel 12, and the diffusion chamber 13. Because the cross-sectional area of ​​the jet channel 12 is smaller than that of the gas-liquid inlet channel 11, the pressure suddenly increases upon entering the jet channel 12, accelerating the flow through the jet channel 12 and increasing the impact force of the water flow, which facilitates the subsequent generation of bubbles. After entering the diffusion chamber 13 from the jet channel 12, the fluid is rapidly ejected. Because the cross-sectional area of ​​the jet channel 12 is smaller than that of the diffusion chamber 13, the pressure suddenly decreases, creating a negative pressure at the outlet of the jet channel 12, further dissolving the gas in the water.

[0046] The gas-liquid mixed fluid here is water with bubbles. The gas-liquid inlet of the water inlet connector can be connected to a Venturi ejector. When water flows through the Venturi ejector, it draws in air, forming a gas-liquid mixed fluid that is then fed into the gas-liquid inlet of the water inlet connector. The cross-sectional area of ​​the diffusion chamber 13 is larger than that of the gas-liquid access channel 11, thereby increasing the pressure difference and boosting the solubility of bubbles in the water.

[0047] Reference Figure 1 、 Figure 2 、 Figures 5 to 7 The bubbler 2 includes at least one bubble channel 211, one end of which is a second gas-liquid inlet 2111 and the other end is a gas-liquid outlet 2112. The second gas-liquid inlet 2111 is connected to the diffusion chamber 13, and the cross-sectional area of ​​the bubble channel 211 gradually increases from the second gas-liquid inlet 2111 to the gas-liquid outlet 2112. The gas-liquid mixed fluid from the diffusion chamber 13 enters the bubble channel 211 from the second gas-liquid inlet 2111. As the cross-sectional area of ​​the bubble channel 211 gradually increases from the second gas-liquid inlet 2111 to the gas-liquid outlet 2112, the gas-water mixed volume is expanded, the pressure gradually decreases, and the gas dissolved in the water turns into bubbles. Combined with the high-speed impact of the water flow on the gas, a large number of micro-nano bubbles are instantly formed. In addition, generally, when in use, the micro-nano bubble generating connector is vertical, with the jet component 1 at the top and the bubbler 2 at the bottom. Because the gas rises lightly, the water flow impacts downward, and the high-speed water impacts the gas, the two are violently mixed, thereby forming a large number of micro-nano bubbles in an instant. In one embodiment, the bubble channel 211 is tapered. The bubble channel 211 can have only one, or multiple and all connected to the diffusion chamber 13.

[0048] Among them, Figure 1、 Figure 2 、 Figure 8 and Figure 9 As shown, the gas-liquid outlet joint 3 is provided with a gas-liquid collection chamber 31 and a terminal connection portion 32 for connecting to a water outlet terminal. The gas-liquid collection chamber 31 is connected to the gas-liquid outlet 2112. The water outlet terminal can be a water faucet or water outlet pipe of a cleaning device. Therefore, the terminal connection portion 32 can be configured as a hollow tube, connected to the gas-liquid collection chamber 31, and can be inserted into the water outlet pipe of the cleaning device to achieve connection. The gas-liquid collection chamber 31 is connected to the gas-liquid outlet 2112, and can receive the liquid (e.g., bubble water) containing a large number of micro-nano bubbles produced by the bubbler 2 and input it from the terminal connection portion 32 to the water outlet terminal of the cleaning device. In addition, the bubbler 2 has multiple bubble channels 211, which can be 2-20, for example 5. In one embodiment, there are 10 bubble channels 211, all of which are connected to the gas-liquid collection chamber 31. The liquid containing a large number of micro-nano bubbles produced by each bubble channel 211 is collected by one gas-liquid collection chamber 31 and inputted together to the water outlet terminal.

[0049] Based on the above structure, the present invention first accelerates the flow rate to mix the water and gas violently, and then expands the water and gas mixing volume to allow the high-speed water flow to impact the gas to generate bubbles, thereby generating more micro-nano bubbles and higher efficiency. In addition, since the jet component 1 and the gas-liquid outlet joint 3 are provided, the gas-liquid supply equipment and the water outlet terminal can be connected respectively, without the need for additional modification of the cleaning equipment, and it is more convenient to use.

[0050] Preferably, refer to Figure 1 、 Figure 2 、 Figures 5 to 7 The bubbler 2 also includes a first expansion tank 212 connected to the second gas-liquid inlet 2111. The first expansion tank 212 is in communication with the second gas-liquid inlet 2111, and an opening is provided at one end of the first expansion tank 212 away from the second gas-liquid inlet 2111. The provision of the first expansion tank 212 can increase the water-gas mixing volume and store some of the gas that is not dissolved in water, allowing the cavity to accommodate more gas and facilitate the generation of more bubbles. The gas-liquid mixed fluid enters the first expansion tank 212 from the diffusion chamber 13 and impacts the tank wall of the first expansion tank 212, causing the gas and liquid to mix more violently, thereby increasing the number of nano-micro bubbles.

[0051] Preferably, refer to Figure 1 、 Figure 2 、 Figures 5 to 7The wall of the first expansion groove 212 is provided with a raised structure 213 that protrudes toward the opening. After the bubbles enter the first expansion groove 212, they impact the raised structure 213, further mixing the gas, liquid, and water in the gas-liquid mixed fluid, generating more bubbles. Specifically, the raised structure 213 is sheet-shaped and / or annular. In one embodiment, the raised structure 213 is annular and sheet-shaped. The annular raised structure 213 is located in the middle, and several sheet-shaped raised structures 213 are located on the outside of the annular raised structure 213 and are radially arranged, dividing the first expansion groove 212 into several blocks, each of which is provided with a bubbling channel 211.

[0052] Preferably, refer to Figure 1 、 Figure 2 、 Figures 5 to 7 A second expansion groove 214 connected to the first expansion groove 212 is further provided on the groove wall of the first expansion groove 212. The second expansion groove 214 further increases the gas-liquid mixing volume, which can increase the water-gas mixing volume and store some gas that is not dissolved in water, so that the cavity can accommodate more gas, which is convenient for generating more bubbles.

[0053] The jet element 1 is threadedly connected to the bubbler 2. Specifically, the jet element 1 is provided with a first threaded section 14, which is provided with an external thread. The bubbler 2 is provided with a first internal thread 215, which can be threadedly connected to the first threaded section 14, thereby connecting the jet element 1 and the bubbler 2. In addition, a sealing ring is provided between the jet element 1 and the bubbler 2 to ensure that the connection between the two will not leak. Similarly, the bubbler 2 is threadedly connected to the gas-liquid outlet joint 3. The bubbler 2 is provided with a second threaded section 216, and the gas-liquid outlet joint 3 is provided with a second internal threaded section 33 that matches the second threaded section 216.

[0055] In addition, if Figures 10 to 13As shown, the bubbler 2 has other settings.

By increasing the number of bubbler parts 21, the content and efficiency of the micro-nano bubbles in the gas-liquid mixed fluid finally discharged can be improved. Accordingly, each bubbler part 21 is provided with a first expansion groove 212, a second expansion groove 214, and a protruding structure 213.

[0056] Among them, the two adjacent bubble parts 21 are threadedly connected, one end of the bubble part 21 is provided with a first internal thread 215, and the other end is provided with a second thread segment 216, the second thread segment 216 is an external thread, and the first internal thread 215 can be connected to the first thread segment 14 of the jet part 1, and can also be connected to the second thread segment 216 of another bubble part 21.
