Description

Axial flow fan Technical Field The utility model belongs to the technical field of axial flow fans, and particularly relates to an axial flow fan. Background The axial flow fan, which is the air flow in the same direction as the axis of the fan blade, can be used for ventilation in large space places such as common factories, warehouses, gymnasiums, and the like, and has very wide application. In the existing axial flow fan, the mesh enclosure around the barrel is fixed through bolted connection, needs to be disassembled and assembled by means of tools, has the problems of troublesome and laborious disassembly and assembly, and can influence the tightness due to the fact that the thread slipping occurs later. The prior patent document (bulletin number: CN 220646227U) discloses an axial flow fan, wherein in the technical scheme, a front net cover and a rear net cover are connected and fixed with a cylinder body through bolts, and the technical problems are also existed. Disclosure of Invention The utility model aims to solve the technical problems in the prior art and provides the axial flow fan which is novel in structure, simple in mesh cover disassembly and assembly, labor-saving, convenient and fast and high in practicability. In order to solve the technical problems, the utility model adopts the following technical scheme: The axial flow fan comprises a barrel, a motor, fan blades and fan blades, wherein the motor is arranged in the barrel, the output end of the fan blades are connected with the fan blades, and the axial flow fan is characterized in that a net cover is detachably connected to the end face of the barrel, fixing arms are circumferentially distributed on the net cover, connecting holes are formed in the fixing arms, each connecting hole comprises a guide hole and an arc-shaped limiting hole, the guide holes are communicated with the arc-shaped limiting holes, limiting pins are arranged on the end face of the barrel, each limiting pin comprises a limiting part and a blocking part, the blocking part is arranged on the limiting part, the cross section diameter of the blocking part is larger than that of the limiting part, the guide holes correspond to the blocking part, and the arc-shaped limiting holes correspond to the limiting parts. This axial fan novel structure, the screen panel dismouting is simple, and is laborsaving convenient, and the practicality is strong. Further, a fixed channel is arranged on the cylinder body, a semiconductor refrigerating sheet is arranged in the fixed channel, and the cold end of the semiconductor refrigerating sheet stretches into the cylinder body and is positioned in front of the fan blade. The external power supply is connected, the cold end of the semiconductor refrigerating sheet refrigerates, the air temperature in the cylinder body is reduced, and the air generated by rotation of the fan blades blows out the cold air outwards, so that the cooling effect on the external environment is good. Further, the semiconductor refrigerating sheet is fixed in the fixed channel through the bolts, so that the semiconductor refrigerating sheet is reliable in fixation, convenient to assemble and disassemble, convenient to overhaul and replace, flexible and convenient to install and use.
