An Elevator Fault Automatic Detection Device

The utility model is related to an automatic elevator fault detection device. When in use, the external air is sucked into the air inlet duct by the fan and blown into the converging space. A low pressure area forms in the intersection space. Since the circuit components are located on both sides of the intersection space, even if there is dust on the circuit components, under the action of air pressure and air flow, the dust will pass through the intersection space and It will reach the air outlet channel to prevent dust from entering. accumulating in the circuit Components, to avoid circuit components caused by dust short circuit.
