AI Technical Summary
Existing fire detection smoke generators release smoke into the external environment during use, affecting the environment and the safety of operators. In addition, the devices are bulky and inconvenient to use.
A negative pressure fan is used, which is connected to a shield via a hose. The fan draws smoke into the filter box, where an activated carbon filter removes harmful substances. An electric push rod covers the smoke detector, and the height of the device is adjusted using an extension rod and fastening bolts.
It effectively reduces the harm of smoke to the environment and operators, improves the convenience and flexibility of use, avoids the spread of smoke, and the device can operate on its own power supply.
