1. In the previous case, in order to improve the moisture damage of electronic control accessories and fans, the anti-return device must maintain a pre-pressure in the closed state to achieve the expected moisture-proof effect. In this way, the fan power requirements are relatively large. It is enough to overcome this pre-pressure, so the fan purchase cost is higher than the general, the more troublesome is that the previous case is quite wasteful of energy and electricity costs when providing agriculture and long-term operation.

2. The entire circuit of the previous case is not equipped with fuses, so when the fan, oscillator or electronic control accessories exceed the predetermined load, they will continue to operate, there is no way to warn of short circuit, overload or leakage, so the safety of use is not enough, especially in A humid working environment is even more dangerous.

3. Without a time controller, it is impossible to realize the automatic and flexible operation function. If the external setting is simply adopted, it will lose safety and destroy the overall appearance.

1. The present invention is equipped with a delay unit in the electric box, which is used to control the fan to continue to run for a set time when the oscillator is momentarily powered off, so as to avoid the residual water mist inside the water tank, thereby eliminating the water mist erosion fan.

2. The bottom surface of the fan of the present invention is installed above the top surface of the water tank to maintain a convection channel connecting the inside and outside between the two. In addition to making the fan less eroded by the water tank moisture during standby, it can also be The high temperature generated by the oscillator for a long time accelerates heat dissipation, so that the oscillator has better operating efficiency and service life, and can simultaneously reduce the water temperature of the tank, so that the temperature of the water mist produced by the oscillator is more conducive to plant growth.
