After violent stirring, the air is crushed into smaller bubbles to become an emulsified soda-water mixture; after passing through the diffuser section of the ejector, the soda-water mixture changes from velocity head to pressure head, and the fine bubbles are further compressed, increasing the solubility of air in water to form dissolved air water; then the dissolved air water is ejected from the diffuser port of the ejector, generating strong vortex stirring in the water body, and a large amount of oxygen is dissolved in the water along with the fine bubbles. The dissolved oxygen is further transported to a distant place through the flow-making effect of the equipment, thus completing the entire oxygen transfer process;
