1. Add pressure sensor: The pressure sensor installed in electric sprayer can monitor the pressure change inside the sprayer. When the pressure reaches the set threshold, the sensor will send a signal to the control system of the sprayer to trigger the shutdown action.
2. Installation of liquid level sensor: Install a liquid level sensor in the liquid storage container of the sprayer. When the liquid level drops to a certain extent, the sensor can detect it and send a signal to the control system to instruct the sprayer to stop working.
3. Design a delay device: By adding a delay device, the working state of the sprayer can be continuously detected for a period of time after the sprayer is started. If the sprayer does not detect working activities within a certain period of time (for example, the trigger is released or the sprayer remains motionless), the retarder will trigger the closing action.
