Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 The nano bubble mixing and pressure regulating device provided by the utility model comprises a shell 1 and an air inlet 2, a liquid inlet 3, and a release port 4 connected to the shell 1, wherein the ports of the air inlet 2, the liquid inlet 3, and the release port 4 are respectively provided with a first valve, a second valve, and a third valve, and a pressure regulating mechanism is provided at the upper end of the shell 1, and the pressure regulating mechanism comprises a piston plate 5 arranged inside the upper end of the shell 1, and an electric telescopic rod 6 arranged outside the upper end of the shell 1, wherein the movable rod of the electric telescopic rod 6 extends to the upper end of the shell 1 and is fixedly connected to the upper surface of the piston plate 5, and the shell 1 is provided with a dissolving gas bin 7 on the lower surface of the piston plate 5, and the shell 1 is also provided with a bubble cutting component in the dissolving gas bin 7.

[0023] The bubble cutting assembly includes a motor 8 arranged on the lower end surface of the shell 1, a rotating shaft 9 arranged inside the lower end of the shell 1, and a plurality of blades 10. The lower end of the rotating shaft 9 is connected to the output shaft of the motor 8. A sleeve 11 is sleeved on the outer side of the upper end of the rotating shaft 9. The upper end of the sleeve 11 passes through the piston plate 5 and the shell 1. The rotating shaft 9 and the blades 10 are connected by a connecting mechanism, and two adjacent blades 10 in the vertical direction are connected by a hinge.

[0024] The sleeve 11 is fixedly connected to the piston plate 5 and sealed at the connection. The sleeve 11 is slidably connected to the perforation on the upper end surface of the shell 1. When the piston plate 5 moves up and down inside the shell 1, the sleeve 11 moves synchronously.

[0025] It can be understood that the blade 10 is evenly provided with a plurality of through holes.

[0026] The connecting mechanism includes a cross slot 12 and a plurality of cross connecting frames 13 provided on the rotating shaft 9. The plurality of cross connecting frames 13 are installed in the cross slot 12 along the vertical direction. The ends of the cross connecting frames 13 are rotatably connected to the end faces of the blades 10, and a compression spring 14 is installed between two adjacent cross connecting frames 13.

[0027] A first sleeve ring 15 is fixedly provided on the upper surface of the top cross connection frame 13 , and the sleeve ring is sleeved on the outer side of the rotating shaft 9 . A second sleeve ring 16 is provided on the lower end surface of the sleeve 11 , and an end face bearing is provided on the lower surface of the second sleeve ring 16 .

[0028] A pressure gauge 17 for detecting pressure is also provided at the upper end of the sleeve 11 .

[0029] The upper end surface of the sleeve 11 is provided with a conduit 18 communicating with the interior, and a fourth valve 19 is installed at the end of the conduit 18 .

[0030] Specifically, when the utility model is used, the electric telescopic rod 6 is controlled to work so that the movable rod of the electric telescopic rod 6 drives the piston plate 5 to move up and down synchronously inside the shell 1, thereby quickly adjusting the pressure of the dissolved gas bin 7 inside the shell 1.

[0031] At the same time, the motor 8 is started, and the motor 8 drives the blades 10 to rotate synchronously through the rotation 9 and the cross connecting frame 13, and the bubbles in the gas dissolving chamber 7 are quickly cut through the rotation of the blades 10.

[0032] In the above process, when the electric telescopic rod 6 is working, the sleeve 11 moves synchronously with the piston plate 5. In combination with the compression spring 14, the sleeve 11 applies a downward force to the multiple cross-connecting frames 13, so that the distance between two adjacent cross-connecting frames 13 is reduced or increased, and then the angle between two adjacent blades 10 in the vertical direction changes, that is, the center line of the through hole of the blade 10 is deflected, and the diameter of the gas bubble is quickly adjusted. In combination with the movement of the sleeve 11 driven by the electric telescopic rod 6, the pressure regulation and the bubble size regulation are achieved by controlling the opening or closing of the third valve of the release port 4 and the fourth valve 19 of the conduit 18.

[0033] The piston plate 5 is driven by the electric telescopic rod 6 to move up and down synchronously inside the shell 1, thereby realizing rapid pressure regulation of the gas dissolving chamber 7 inside the shell 1. This structure can significantly improve the efficiency of mixing and pressure regulation, so that the bubbles are more evenly dispersed and dissolved in the liquid, thereby improving the mixing effect. The device provided by the utility model can improve the mixing efficiency by 20%,

[0034] The combination of the motor 8, the rotating shaft 9 and the blade 10 can quickly and accurately cut the bubbles in the gas dissolving chamber 7. The center line of the through hole of the blade 10 is deflected, which can realize the rapid adjustment of the bubble diameter, thereby controlling the size and distribution of the bubble and improving the mixing accuracy. It can also effectively reduce the average value of the bubble diameter and reduce the distribution range of the bubble diameter, thereby improving the uniformity of the bubble.

[0035] Through the design of the compression spring 14 and the cross connecting frame 13 in the connecting mechanism, the sleeve 11 can adjust the force of the multiple cross connecting frames 13, thereby achieving the angle change between two adjacent blades 10 in the vertical direction. This automatic adjustment mechanism enables the device to automatically adjust the mixing parameters as needed, thereby improving the intelligence and adaptability of the mixing.

[0036] A pressure gauge 17 for detecting pressure is provided in the device. Through the combination of the conduit 18 and the fourth valve 19, real-time monitoring and adjustment of the pressure in the gas dissolving chamber 7 can be achieved. This helps to ensure that the appropriate pressure is maintained during the mixing process, and improves the stability and controllability of the mixing. The opening and closing of the third valve of the release port 4 and the fourth valve of the conduit 18 can achieve rapid release of the gas, making the entire mixing process more flexible and efficient.
