Specifically, the formation of the dissolved air water is formed by mixing compressed air and clear water, the air and the water are not easy to separate due to the fact that the pressure in the dissolved air water tank is high, in the process that the dissolved air water extrudes the core block 22 from the water inlet pipe 21 and enters the shell 20, the elastic force of the first elastic piece is increased by the dissolved air water extrusion core block 22, the energy consumption process is carried out, then the pressure in the shell 20 is far smaller than the pressure in the dissolved air water tank after the dissolved air water enters the shell 20, the pressure is reduced, a large amount of microbubbles generated by quick release of the air dissolved in the water are discharged from the water outlet pipe 23, in the embodiment, the first wave plate 27 is arranged on the lower bottom plate in the shell 20, then the dissolved air is directly impacted to the first wave plate 27 through the intermittent space formed by the core block 22 and the ring body 26 after the core block 22 is separated from the pipe orifice of the water inlet pipe 21, the dissolved air and the first wave plate 27 form multidirectional impact, after the power of the air compressor is regulated to any fixed value, compressed air enters the dissolved air tank, the compression of the air has certain frequency change, namely the force of the dissolved air to extrude the core block 22 is slightly changed within a certain range, so that the core block 22 can slide back and forth along the axial direction on the outer cylinder 24 under the action of the elastic force of the first elastic piece, then the power generated when the inner cylinder 25 moves on the outer cylinder 24 is transferred to the first wave plate 27 through the first transmission component 28, so that the first wave plate 27 can slide back and forth along the radial direction on the lower bottom plate under the action of the second elastic piece, the first wave plate 27 and the washed dissolved air can mutually collide, the first wave plate 27 is equivalent to the radial reciprocating vibration, the advantage of the arrangement is that the acting force generated by the water flow impacting the core block 22 is utilized, by using the force to vibrate the first wave plate 27, the dissolved air water can be quickly dissipated by vibration, the air in the dissolved air water can be quickly released, and the release rate of the air in the dissolved air water can be improved.
