The air purification device can assist in the removal of excrement. Harmful and odorous gas, improve the air environment in the cabin.

The invention discloses a ladder anti-dumping safety system based on angle detection and alarm function. The system is mainly composed of a gyroscope, a relay, a logic judgment part, a power supply, a sound-light alarm part and a communication part. By means of the angle detection system with the gyroscope as the core part, the safe use of a ladder is ensured. The angle between the ladder and the ground is detected through the gyroscope, signals are sent to the logic judgment part, and whether the ladder currently is in a safe state or not is judged through the logic judgment part. Once it is judged that the ladder is in an unsafe state, the system can trigger sound-light alarm to remind a user, and the communication part sends the unsafety information to a supervisor. Due to the arrangement of the relay, it is ensured that the power supply is powered on all the time when people work on the ladder and powered off when people climb down the ladder.
