The working process of the humidifier provided by the embodiment is as follows:

the mist generating means in the base 16 is located below the humidifier and water in the water reservoir above it can flow into the base 16 continuously. When the water in the water tank located below is insufficient, the water tank located above will continue to be replenished. When the amount of water in the water tank is sufficient, the water in the water tank pushes the floating plate 141 so that the protrusion 143 does not contact the valve body 3, and a certain interval exists between the protrusion 143 and the bottom of the valve body 3. When the water volume in the water tank that is located the below is not enough, because the center setting of floating plate 141 is in the one side that the protruding portion 143 was kept away from to floating plate 141, the one end that the protruding portion 143 was kept away from to floating plate 141 this moment will take place to sink under the effect of gravity, and the one end of protruding portion 143 will take place to warp simultaneously, and protruding portion 143 will jack-up valve body 3 this moment for form the rivers passageway in the drainage device, the water that is arranged in the water tank of top will enter into the water tank of below through the rivers passageway, carry out the moisturizing operation to the water tank. When the water tank in the lower water tank is increased to a certain extent, the buoyancy generated by the water pushes the floating plate 141, so that the protrusion 143 moves downward, and at this time, the water flow passage is closed by the spring 4, and the filling of the lower water tank is completed. The above-mentioned actions are repeated until all the water in all the water tanks located above are completely emptied.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
