The water flow with bubbles enters the tail portion 42 via the flow-through portion 44, and the water in the tail portion 42 flows out through the mesh 60, at which time the fine holes 61 on the mesh 60 further cut the bubbles in the water, thereby generating micro bubbles.
Because the mold of the vortex column is complicated to manufacture when the vortex column is directly arranged in the accommodating cavity of the gas-liquid mixing pipe, the invention is provided with the vortex column shell, so that the vortex column is arranged in the vortex column shell, and then the vortex column shell with the vortex column is arranged in the accommodating cavity of the gas-liquid mixing pipe, thereby improving the manufacturing efficiency.
The microbubble generator provided by the invention enables water to generate vortex which rotates at high speed through the vortex column, and to continuously accelerate when passing through the gas-liquid mixing pipe, so that air is rapidly cut to generate bubbles, and finally, the bubbles are further scattered and cut through the hole net to form microbubbles, so that the microbubble generator is simple in structure and convenient to use. In order to prevent water from flowing back due to large water flow, a protruding part is arranged on the inner wall of the gas-liquid mixing pipe to block water flow, so that water flow is prevented from flowing out through the air inlet and the air inlet hole.
The present invention has been described in detail with reference to the drawings and embodiments, and one skilled in the art can make various modifications to the invention based on the above description. Accordingly, certain details of the illustrated embodiments are not to be taken as limiting the invention, which is defined by the appended claims.
