At the bottom of the first control valve 45, a jet injector 44 is fixedly connected (the jet injector is an existing jet injector on the market. The jet injector uses one or more nozzles to eject a high-speed fluid (usually called the "main fluid"). The main fluid flows out through the nozzle at a relatively high speed, forming a high-speed flowing jet. Due to the injection of the high-speed fluid, a low-pressure area will be formed around the nozzle. This low-pressure area will cause the surrounding fluid (usually the "suction fluid") to be sucked into the jet injector and enter the mixing area with the main fluid. The suction fluid and the main fluid are mixed in the mixing area. Due to the kinetic energy and flow rate of the main fluid, the mixing process is often very rapid and uniform, and the mixed fluid flows out through the outlet of the jet injector), and the first control valve 45 is used to connect the jet injector 44 and the third connecting pipe 46. On the right side of the jet injector 44, a delivery pump 43 is fixedly connected, and the jet injector 44 is used to fix the delivery pump 43.

The output end of the motor 2 is fixedly connected to a transmission rod 21. The motor 2 drives the transmission rod 21 to rotate. At the bottom end of the transmission rod 21, a mixing paddle 22 is fixedly connected. The transmission rod 21 drives the mixing paddle 22 to rotate.

[0041] Working principle: When the hypochlorous acid solution preparation device is operating, first, sodium hydroxide solution is conveyed into the reaction barrel 1 through the second control valve 6. At the same time, the motor 2 drives the mixing paddle 22 to rotate by means of the transmission rod 21. While stirring the solution, it also conveys the top solution downward. Then, chlorine gas is conveyed into the spiral tube 31 through the first air inlet pipe 3, and the chlorine gas is refined into bubbles with a smaller diameter through the spiral tube 31, and the refined chlorine gas bubbles are conveyed into the sodium hydroxide solution for reaction. After that, the top solution is extracted by the delivery pump 43 by means of the second connecting pipe 42, the three-way valve 41 and the first connecting pipe 4, and is conveyed back into the reaction barrel 1 through the ejector 44. During this process, the gas at the top of the reaction barrel 1 is extracted by the ejector 44 through the third connecting pipe 46 and the fourth connecting pipe 48, and after being remixed inside the right side of the ejector 44, it is ejected at a high speed, so as to continue the reaction inside the reaction barrel 1. At the same time, the high-speed ejected gas-liquid mixed fluid forms a vortex inside the reaction barrel 1, thereby increasing the lateral stress of the bubbles, enabling the bubbles to stay in the same water layer for a longer time and carry out a long-time reaction. After the mixing is completed, by rotating the three-way valve 41, the first connecting pipe 4 is connected to the communicating pipe 5, and cleaning water can be conveyed into the reaction barrel 1 to facilitate subsequent cleaning.
