This utility model belongs to the field of tobacco technology and discloses an exhaust device, including an exhaust hood, a sensor, and a control module. The exhaust hood is positioned above a vibrating trough and is equipped with a lifting device that drives the exhaust hood to move vertically, ensuring that the exhaust hood has at least two states: raised and lowered. The sensor is located on the bottom end of the exhaust hood facing the vibrating trough. The control module is electrically connected to both the sensor and the lifting device. By installing the sensor on the bottom end of the exhaust hood, where the operator is easily squeezed, when the exhaust hood descends due to misoperation, the sensor at the bottom of the exhaust hood comes into contact with the operator during the cleaning process. The sensor converts the pressure into a change in resistance and sends a signal to the control module. The control module then sends a signal to the lifting device to stop descending and resume ascending, preventing the operator from being squeezed. This proactive protection of stopping upon contact significantly improves the safety of the exhaust device, resulting in a high accident prevention rate.

This utility model relates to the field of forklift AGV technology, specifically a safety stop triggering device for forklift AGVs, including a fixed base plate, side blocks, guide baffles, detection handle blocks, connecting frames, detection sensors, detection sensor mounting brackets, and detection plates. When the detection handle block is activated and moves close to the fixed base plate, the detection plate, driven by the connecting frame, moves away from the detection end of the detection sensor. Upon detecting the detection plate's misalignment, the detection sensor sends a signal to the corresponding forklift AGV controller, causing the controller to initiate an emergency stop, preventing further accidents. The device is simple in structure and reliable in use. Furthermore, by adding a laser scanning sensor, this utility model can further enhance safety protection for the forklift AGV's forklift movement and improve its accident prevention capabilities.
