Specifically, the atomizing sheet 4 is connected to the atomizing bin 5, the atomizing bin 5 and the liquid storage bin 6 are separated by a partition plate 70, and are connected by an overflow groove 51, the overflow groove 51 is located above the partition plate 70, when the liquid level in the liquid storage bin 6 exceeds the height of the partition plate 70, the liquid in the liquid storage bin 6 will flow into the atomizing bin 5 through the overflow groove 51.

Specifically, the liquid level sensor 50 is located on the wall of the atomization bin 5 and has a certain limit height for maintaining the liquid level in the atomization bin 5 so that the liquid level in the atomization bin 5 is always at an appropriate height, thereby ensuring that the atomization amount is at a stable level.

Specifically, the liquid level control system 7 is connected to the liquid storage tank 6, and its function is that when the liquid level sensor 50 detects that the liquid level in the atomization tank 5 is low, the liquid level control system 7 raises the liquid level in the liquid storage tank 6 to the height of the overflow tank 51, and then allows the liquid in the liquid storage tank 6 to enter the atomization tank 5 until the liquid level in the atomization tank 5 reaches the limit height of the liquid level sensor 50.

In this embodiment, an optional overflow structure in the liquid level control system 7 is that a first piston plate 8 is arranged at the bottom of the liquid storage tank 6, the edge of the first piston plate 8 is sealed with the tank wall 61 of the liquid storage tank, and a push rod 81 is arranged on the back of the first piston plate 8. The lower part of the push rod 81 is engaged with the transmission gear of the micro servo motor 80, and the lifting and lowering of the first piston plate 8 is controlled by the forward and reverse rotation of the micro servo motor 81.

The working principle of the overflow structure in Example 1 and Example 2 is as follows: when the liquid level sensor 50 detects that the liquid level in the atomization bin 5 is lower than the limit height, the liquid level control system 7 controls the piston plate in the liquid storage bin 6 to move upward, so that the liquid level in the liquid storage bin 6 is higher than the partition plate 70, so that the liquid in the liquid storage bin 6 continuously enters the atomization bin 5 through the overflow groove 51 until the liquid level in the atomization bin 5 is replenished to the limit height.

In this embodiment, the overflow structure includes a flow valve 52 embedded in the bottom of the partition plate 70 , and the flow valve 52 communicates with the bottom of the atomization bin 5 and the bottom of the liquid storage bin 6 .

Its working principle is: when the liquid level sensor 50 detects that the liquid level in the atomization bin 5 is lower than the limit height, the liquid level control system 7 controls the opening of the flow valve 52, so that the liquid in the liquid storage bin 6 enters the atomization bin 5 through the flow valve 52 until the liquid level in the atomization bin 5 is replenished to the limit height.

Furthermore, when the liquid level control system 7 uses the flow valve 52 to control the liquid level, the bottom of the liquid storage bin 6 must be no lower than the bottom of the atomization bin 5 to ensure that all the liquid in the liquid storage bin 6 can flow into the atomization bin 5 .
