And then in the use of lampblack absorber, when meetting the barrier, can in time remind the user through the work of reporting to the police. The driving device is a driving motor.
The working process of the range hood is described with reference to fig. 1 and 2, when the range hood works normally, the movable air duct rises, the movable air duct completes work after moving to a specified position, and at the moment, the standby running state of the main fan of the range hood is achieved. After the range hood in this embodiment starts the switch, the displacement detection device 40 located at the top end of the panel can convert the input displacement change signal of the extension spring into an electric signal and output the electric signal to the single chip microcomputer, so as to control the motor and the buzzer of the lifting moving part to work as required.
When no barrier exists on the panel, after the motor is started, the displacement sensor detects that the spring has no displacement change, the movable air duct works normally, and after the movable air duct reaches a preset working position, the moving part finishes working and stops moving;
when foreign matters exist on the panel or the lifting device touches an upper obstacle in the lifting process, after the lifting motor is started, the movable top cover is stressed, the telescopic spring is compressed, and the displacement sensor detects the stroke change, sends a signal to the controller to start the buzzer to alarm, and suspends the operation of the motor; when the user removes the obstacle, the displacement sensor senses the stroke to reset, and then sends a signal to the controller to stop the buzzer from working, restart the motor and continue working.
When the air duct descends, after the lifting motor is started, the telescopic spring can be stretched to cause stroke change after the foreign matter is blocked, the stroke change can be detected by the displacement sensor to be sensed, a signal is sent to the controller to start the buzzer to give an alarm, and the motor is suspended.
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 therefrom are within the scope of the invention.
