Liquid in liquid bath 2 can continue to flow into liquid storage canal 6.When the liquid level in liquid storage canal 6 rises above reservoir outlet 10
When, ambient atmos can not be entered in reservoir 2 by reservoir outlet 10, then the liquid in reservoir 2 just stops to liquid storage
Flowing in canal 6.Now the liquid level of whole ultrasonic atomizatio equipment be maintained for it is motionless, when outside sonic oscillation circuit is started working
When, the liquid level in submerged soil 12 declines, and because the connection for leading canal 11 is acted on, the liquid level of liquid storage canal 6 also declines, when liquid storage canal 6
The highest point that liquid level drops to liquid storage canal outlet 10 exposes liquid level, and air can enter reservoir 2 in the manner described previously again,
And then realize that the liquid in air pressure balance, reservoir 2 can be just flowed in liquid storage canal 6, until the liquid level in liquid storage canal 6 is high again
10 are exported in liquid storage canal.And so on, be achieved that reservoir 2 according to user with liquid demand from the additive liq of trend liquid storage canal 6
