In the embodiment of the present application, the diameter of the air inlet 112 is 2-3 mm, the diameter of the air inlet 112 is related to the inner diameter of the air inlet hose, generally, the diameter of the air inlet 112 is equal to the inner diameter of the air inlet hose, and in other embodiments, the diameter of the air inlet 112 may be specially set according to the inner diameter of the air inlet hose and some requirements. For example, the diameter of the inlet 112 may be 1-5 millimeters, etc. In order to allow the gas entering through the gas inlet 112 to reach the mixing chamber 111, the flow cross section is abruptly increased, so that the flow velocity is reduced to almost zero and the total pressure is almost entirely converted to static pressure, so that the solubility of the gas in the aqueous solution is increased. In the embodiment of the present application, the cross-sectional area of the mixing chamber 111 parallel to the cross-section of the air inlet 112 is greater than 2500 square millimeters, and in particular, in the embodiment of the present application, the cross-sectional area of the mixing chamber 111 parallel to the cross-section of the air inlet 112 is 2500-. In other embodiments, the cross-sectional area of the mixing chamber 111 in a cross-section parallel to the air inlet 112 may also be slightly less than 2500 square millimeters.
In the embodiment of the present application, the gas mixing box 110 is a cuboid, and the ratio of the cross-sectional area of the mixing chamber 111 to the cross-sectional area of the water inlet 113 is large, which easily causes the height of the aqueous solution in the mixing chamber 111 to be small, so that the height of the aqueous solution in the mixing chamber 111 can be increased by arranging the water collecting tank 117 in the embodiment of the present application, the path of the gas passing through the aqueous solution is increased, and the gas dissolved in the aqueous solution is sufficient; and this application embodiment is through setting up water catch bowl 117, can improve the great condition that causes of bottom area of mixing chamber 111 that the mixing chamber 111 catchments, and water catch bowl 117 floor area that this application embodiment set up is less relatively, improves the condition that microbubble generating device 100 catchments bottom after using up.
In the present embodiment, the depth of the water collecting groove 117 increases along the direction from the water outlet pipe 115 to the drain 1110. In the embodiment of the present application, along the direction from the water outlet pipe 115 close to the end of the water outlet 114 to the water outlet pipe 1110, the depth of the water collecting tank 117 is increased, so that when the water collecting tank 117 circulates to the water outlet pipe 115 through the water outlet pipe 1110, the gravitational potential energy of the aqueous solution is converted into kinetic energy, so that the aqueous solution smoothly circulates to the water outlet pipe 115 through the water outlet pipe 1110, and the aqueous solution can flow out through the water outlet pipe 115 to form micro bubbles.
In the present embodiment, the sump 117 includes a first bottom surface 1171 and a second bottom surface 1172, and the first bottom surface 1171 and the second bottom surface 1172 form a step structure such that the sump 117 increases in depth. In the embodiment of the present application, by providing the step structure, the depth of the water collecting tank 117 is increased, so that when the aqueous solution of the water collecting tank 117 flows toward the drain 1110, the gravitational potential energy of water is converted into kinetic energy, so that the aqueous solution flows from the water collecting tank 117 to the water outlet pipe 115, and the flow is smooth. The embodiment of the present application includes a step structure formed by the first bottom surface 1171 and the second bottom surface 1172, in other embodiments, the number of the step structures may be two or more, for example, the number of the step structures may be two, three or four, and the like, and the water collection groove 117 may be correspondingly provided with a plurality of bottom surfaces, for example, three, four or five bottom surfaces, and the like. In the embodiment of the present application, the bottom surface of the water collecting groove 117 is located on the outer surface of the water outlet pipe 115. By setting the bottom of the water collecting tank 117 to be a step structure, the embodiment of the present application can reduce the remaining of the aqueous solution in the water collecting tank 117 when the microbubble generating device 100 is turned off. In other embodiments, the bottom surface of the water collection groove 117 may be provided as an inclined bottom surface such that the depth of the water collection groove 117 gradually increases toward the drain 1110.
In the present embodiment, the width of the water collection tank 117 decreases along the direction from the water outlet pipe 115 to the drain 1110. By providing a water collection channel 117 that decreases in width in the direction from outlet tube 115 near the end of outlet 114 to collector 1110, the depth of water collection channel 117 near the end of collector 1110 increases and the volume of the aqueous solution is similar or identical to the volume of the rest of the water collection channel 117, increasing the distance of gas passing through the aqueous solution. When the amount of aqueous solution in the water collection tank 117 decreases, or the water inlet 113 stops feeding water into the mixing chamber 111, the width of the water collection tank 117 near the end of the drain 1110 is smaller, so that the depth of the water collection tank 117 near the end of the drain 1110 is still higher, so that the distance for gas to pass through the aqueous solution is larger, and the gas is more soluble in the aqueous solution. Meanwhile, when the amount of the aqueous solution in the water collection tank 117 is small, the larger gravitational potential energy can still be maintained, so that the amount of the aqueous solution flowing out of the water outlet pipe 115 is uniform, the amount of the bubbles generated by the micro-bubble generation device 100 in the initial stage of generating micro-bubbles, the intermediate process stage and the stage of ending soon is uniform, and the generated bubbles are in the micro-nano level. Also, in the embodiment of the present application, by setting the width of the water collection tank 117 to decrease toward the drain 1110, the remaining amount of the aqueous solution in the water collection tank 117 at the end of the microbubble generation device 100 can be reduced.

In the embodiment of the application, the first side surface and the second side surface are located on the same side, and the first side surface and the second side surface form a step surface, the width of the water collecting tank 117 in the direction towards the water outlet 1110 can be reduced by setting the side surface of the water collecting tank 117 into a step structure, so that the height of the aqueous solution in the water collecting tank 117 is higher under the condition of the same water quantity, the distance of gas passing through the aqueous solution is increased, and the gas and the aqueous solution can be fully mixed; the amount of residual water in the water collection tank 117 after the operation of the microbubble generation device 100 is completed is small. The step surfaces of the step structures formed by the first side surface and the second side surface in the embodiment of the present application, and the first bottom surface 1171 and the second bottom surface 1172 form a step surface coplanar with each other, so that the water collecting tank 117 is easy to manufacture; in other embodiments, the step surfaces of the step structures formed by the first side surface and the second side surface of the embodiments of the present application, and the step surfaces forming the step structures with the first bottom surface 1171 and the second bottom surface 1172 may not be coplanar.
