Description

Technical Field

[0001] The utility model relates to the technical field of fire smoke exhaust fans, in particular to a fire smoke exhaust fan which is convenient to disassemble and assemble. Background Art

[0002] Fire smoke exhaust fans are fans that supply air to escape corridors. They deliver outdoor wind pressure into indoor spaces. When a fire occurs in a building, a large amount of smoke, carbon monoxide and other toxic gases will be produced, blocking the line of sight. Positive pressure fans supply air to the escape fire stairs, preventing indoor smoke from reaching the stairs, creating conditions for people to escape.

[0003] For example, the utility model with application number CN202323188828.8 relates to the field of fire smoke exhaust, and in particular to a fire smoke exhaust fan. When the motor is working, the coolant in the cavity flows into the heat dissipation cavity and mixes with the coolant in the heat dissipation cavity, which greatly reduces the temperature of the motor, and the heat in the heat dissipation cavity is transferred to the metal sheet position, radiated to the outside air through the metal sheet, and the motor drives the fan blades to rotate. When the fan blades rotate, airflow is formed. When the airflow passes through the metal sheet position, the hot air at the metal sheet position is taken away. However, when the existing fire smoke exhaust fan is working, the suction force generated causes the air to flow from the inside, and a thick layer of dust and oil is easily adhered to the cylinder wall and its blades, affecting the normal operation of the fan. The cylinder itself is usually in the shape of a circular cylinder, which is inconvenient to disassemble and assemble, resulting in inconvenience in cleaning.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a fire smoke exhaust fan that is easy to disassemble and assemble is provided. Utility Model Content
