DETAILED DESCRIPTION

[0027] The utility model is further explained below in combination with the drawings and embodiments.

[0028] As Figures 1-9 shown, the utility model relates to a double-cavity bubble generator, including water inlet piece 1, water outlet piece 2, the intermediate piece 5 for connecting water inlet piece 1 and water outlet piece 2, be equipped with first recess 14 on water inlet piece 1, be equipped with second recess 24 on water outlet piece 2, be equipped with upper recess 51 and lower recess 52 on intermediate piece 5, and the upper recess 51 is communicated with the lower recess 52 through second through-hole 53, and first recess 14 is connected to form first cavity 6 with the upper recess 51, and second recess 24 is connected to form second cavity 7 with the lower recess 52, and first bubble center piece 3 is equipped in first cavity 6, and second bubble center piece 4 is equipped in second cavity 7, and the slit for gas inflow is equipped between first bubble center piece 3 and first cavity 6, and between second bubble center piece 4 and second cavity 7.

[0029] First recess 14 top is equipped with water inlet end wall 15, and water inlet end wall 15 is equipped with first through-hole 151, and first bubble center piece 3 is equipped with first water inlet hole 311, and second bubble center piece 4 is equipped with second water inlet hole 411, and first through-hole 151 is communicated with first water inlet hole 311, and second through-hole 53 is communicated with second water inlet hole 411.

[0030] When water flow enters first water inlet hole 311, first will pass through first through-hole 151, according to Bernoulli equation P1+1 / 2rhoV1 2 +rhoGh1=P2+1 / 2rhoV2 2 +rhoGh2, wherein P is the pressure of a point in fluid, V is the speed of the point in fluid, rho is fluid density, g is gravitational acceleration, h is the height of the point, can know that the flow rate of water flow at first water inlet hole 311 is greater than the flow rate of water flow at first through-hole 151, and the pressure of water flow at first water inlet hole 311 is less than the pressure of water flow at first through-hole 151, so, after water flow passes through first through-hole 151, air will be sucked into water flow channel because of the smaller water flow pressure.

[0031] Because the gap is arranged between the accommodating space and the bubble center piece, the space for air entering the water flow channel is smaller, according to the Venturi effect equation: P2-P1=1 / 2rhoV2 2 -V1 2 , wherein P is the pressure of a point in fluid, V is the speed of the point in fluid, rho is fluid density, can know that the speed of air entering the water flow is faster due to the smaller space for air entering the water flow channel. So when air enters the water flow channel, air cuts the water flow at a very fast speed, so that air bubbles are mixed in the water flow.

[0032] Similarly, the water flow mixes bubbles in the water flow again at the second through hole 53 and the second water inlet hole 411, thereby increasing the bubble concentration in the bubble water. In the present embodiment, two cavities are used, and more cavities can be used to repeatedly mix more bubbles in the water flow and increase the bubble concentration in the bubble water.

The first filter screen 33, the second filter screen 34, the third filter screen 43, and the fourth filter screen 44 each include three layers of filter screens.

[0035] Each layer of filter screen has a pore size of 80-200 mesh.

[0038] The first water inlet section 11 has a first connector 16 arranged thereon, and the first connector 16 has a first clamping jaw 17 arranged thereon.
