In some embodiments of the present invention, the ratio between the width dimension of the mixing chamber 9 in the left-right direction and the width dimension of the dissolved water chamber 10 in the left-right direction is in the range of 1/5 to 1. That is, in the left-right direction, the ratio between the width dimension of the mixing chamber 9 and the width dimension of the dissolved water chamber 10 is in the range of one fifth to one, and when the ratio between the width dimension of the mixing chamber 9 and the width dimension of the dissolved water chamber 10 is less than one fifth, the width dimension of the mixing chamber 9 in the left-right direction is small, and sufficient air bubble mixed flow cannot be generated in the mixing chamber 9, thereby affecting the bubble content of the dissolved water and the quality of the dissolved water; when the ratio between the width dimension of the mixing cavity 9 and the width dimension of the dissolved water cavity 10 is greater than 1, the width dimension of the mixing cavity 9 in the left-right direction is large, the width dimension of the dissolved water cavity 10 in the left-right direction is small, air bubbles in the mixing cavity 9 are mixed more, the water to be dissolved in the dissolved water cavity 10 is less, and the air bubbles are mixed into water and cannot be completely dissolved into the water, so that the waste of resources is caused, and the use requirement of the dissolved water by a user is influenced.

Therefore, the volume capacity of the dissolved water cavity 10 is ensured to be enough for users to use, and the content of micro-nano bubbles in the air bubble mixed flow is ensured to be sufficient, so that the economical practicability of the dissolved air tank 100 is improved.

In some embodiments of the present invention, the ratio between the height of the partition plate 2 in the up-down direction and the inner diameter dimension of the housing 1 at the position corresponding to the partition plate 2 is between 0.4 and 0.9. That is to say, the height of the partition board 2 in the vertical direction is in the range of 0.4 to 0.9 relative to the inner diameter of the casing 1 at the position corresponding to the partition board 2, when the height of the partition board 2 in the vertical direction is smaller than 0.4 relative to the inner diameter of the casing 1 at the position corresponding to the partition board 2, the air bubble mixed flow can only enter the dissolved water cavity 10 through the through hole 21 of the partition board 2, the air bubble mixed flow is less, and the air bubble mixed flow is incompletely and unevenly mixed with water, so that the content of micro-nano bubbles in the micro-nano bubble water is reduced, and the quality of the micro-nano bubble water is reduced.

When the ratio of the height of the partition board 2 in the up-down direction to the inner diameter of the shell 1 corresponding to the partition board 2 is larger than 0.9, the distance between the upper side of the partition board 2 and the upper end of the shell 1 is larger, a large amount of air bubble mixed flow directly enters the dissolved water cavity 10 from the upper end of the partition board 2 through the mixing cavity 9, the air bubble mixed flow in the main cavity 13 is not completely and uniformly mixed with water, the quantity of micro-nano bubbles in the micro-nano bubble water is reduced, and the quality of the micro-nano bubble water is reduced.

Therefore, the ratio of the height of the partition board 2 in the vertical direction to the inner diameter size of the position of the shell 1 corresponding to the partition board 2 is between 0.4 and 0.9, the mixing speed of the air bubble mixed flow and the water in the main cavity body 13 is accelerated, and meanwhile, the air bubble mixed flow and the water are fully mixed.

For example, the ratio between the height of the partition plate 2 in the up-down direction and the inner diameter dimension of the casing 1 at the position corresponding to the partition plate 2 may be: 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, etc.

Further, the periphery of the partition board 2 is formed with a connecting flange 22 extending along the axis of the housing 1, the partition board 2 is connected with the inner peripheral wall of the housing 1 by welding through the connecting flange 22, and the connecting flange 22 increases the welding area of the partition board 2 and the inner peripheral wall of the housing 1, so that the welding strength of the partition board 2 and the housing 1 is enhanced.

Further, the connecting flange 22 includes a plurality of flange portions arranged at intervals in the circumferential direction of the separator 2, and the interval between two adjacent flange portions gradually increases in a direction from the fixed end toward the free end of the connecting flange 22 (e.g., a direction from right to left as viewed in fig. 8). That is, the distance between the adjacent burring parts at the position of the fixed end is small, the distance between the adjacent burring parts at the position of the free end is large, and the distance between the adjacent burring parts at the position of the fixed end is smaller than the distance between the adjacent burring parts at the position of the fixed end.
