Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to an energy-saving fire-fighting smoke exhaust axial flow fan. Background Art

[0002] Axial flow fans are fans that move air in the same direction as the axis of the fan blades. For example, electric fans and air conditioner outdoor fans are fans that run in an axial flow manner. They are called "axial flow" because the air flows parallel to the fan axis. Axial flow fans are usually used in situations where the flow rate requirements are high and the pressure requirements are low. Axial flow fans are fixed in place and move air.

[0003] An existing energy-saving fire smoke exhaust axial flow fan can refer to the utility model patent with Chinese patent announcement number CN220081699U3, which discloses an energy-saving fire high-temperature smoke exhaust axial flow fan, which belongs to the field of fans, and includes: the air outlet end of the fan is equipped with a connecting tube; a fan cover, the fan cover is fixedly connected with two connecting ears, the fan cover and the connecting tube are set against each other, and the two connecting ears are slidably connected in the connecting tube, one of the connecting ears is penetrated with a limiting hole, and the connecting tube is equipped with a plug rod slidably connected in the limiting hole, and the two connecting ears are symmetrically distributed on the fan cover. The pull block of the utility model drives the plug rod to move and disengage from the limiting hole, and the fan cover is pulled outward to make the connecting ear disengage from the connecting tube, so that the fan cover can be removed, which is convenient and quick, and a single staff member can complete the disassembly. Under the limit of the limit block, the connecting ear can be guided and the limiting hole can be opposite to the plug rod, so that the plug rod can be inserted into the limiting hole, and the installation is faster and the stability after installation can be guaranteed.
