Description

Technical Field

[0001] This application relates to the technical field of ceiling fans, and particularly to an industrial ceiling fan. Background Art

[0002] Industrial ceiling fans are commonly used in large spaces such as industrial plants, logistics warehouses, waiting rooms, exhibition halls, stadiums, shopping malls, etc. as a common industrial machine for space ventilation and personnel cooling. It can project a large amount of air flow to the ground, forming a horizontal movement of the air flow layer at a certain height on the ground, thus promoting the overall air circulation and being widely popular in the market.

[0003] In the prior art, the connection between the fan blades and the motor of the ceiling fan is often relatively weak. The fan blades are usually directly connected to the motor respectively by split fasteners. However, the ceiling fan vibrates a lot during operation, which easily causes the problem of loosening of the fasteners and poses a great potential safety hazard.

[0004] In view of this, it is necessary to propose a new industrial ceiling fan to solve the above problems. Summary of the Invention

[0005] In view of the above problems, this application proposes an industrial ceiling fan. By providing a mounting base plate that can connect the fan blades and the main body of the ceiling fan into a whole, the stable connection of the fan is realized, and the structure is relatively ingenious and simple, achieving the beneficial effects of stable installation, convenient installation, convenient production, cost reduction, and efficiency improvement. The industrial ceiling fan is specifically realized through the following technical solutions:

[0006] An industrial ceiling fan, comprising: a housing, a motor, and fan blades. The motor is disposed inside the housing, and the motor shaft of the motor extends out of the housing. The fan blades are detachably disposed on the housing. The housing is provided with a mounting base plate for connecting the housing and the fan blades simultaneously. The mounting base plate is provided as an integral structure. The mounting base plate includes a main body and a connecting portion. The main body is connected to the housing, and the connecting portion is connected to the fan blades.

[0007] Further, the main body is provided as a disc having the same size as the surface of the housing where the motor shaft extends out. The disc is closely attached to the housing. Through this setting, the connection between the mounting base plate and the housing is made compact, making the overall structure more stable and compact.

[0008] Further, a plurality of first mounting holes are formed in the disc, and the housing is provided with first threaded holes corresponding to the first mounting holes. When the disc is closely attached to the housing, the disc is detachably connected to the housing by screwing a screw through the first mounting hole and threadedly connecting it to the first threaded hole. Through this setting, the connection between the disc and the housing is facilitated, and convenient disassembly can also ensure good connection strength.

[0009] Further setting: The connecting part is arranged to be evenly distributed along the outer edge of the main body and is an extension block extending outward from the center of the main body to the periphery. With this setting, the energy conversion of the ceiling fan during rotation is more reasonable and efficient, and the blown air is more stable and powerful.

[0010] Further setting: The fan blade is arranged as a hollow fan blade with a cross-section similar to a water droplet shape, and the extension block is inserted into the cavity inside the inner end of the fan blade. With this setting, the weight of the fan blade is reduced and the cost is lowered.

[0011] Further setting: The extension block is provided with a second mounting hole, and the fan blade is provided with a second threaded hole. When the extension block is connected to the fan blade, the connection between the extension block and the fan blade is realized by setting a screw to penetrate through the second mounting hole and the second threaded hole. With this setting, the connection between the fan blade and the extension block is convenient to disassemble and can also ensure good connection strength.

[0012] Further setting: The number of the connecting parts is set to be multiple, and the number of the connecting parts is the same as the number of the fan blades. With this setting, the force on the extension block and the fan is evenly distributed, it is not easy to be damaged, and the overall structure is more stable and reliable.

[0013] Further setting: The fan blade is provided with a windward side and a leeward side. The windward side is in the same direction as the rotation direction of the motor, and the leeward side is set to be the opposite side of the windward side. With this setting, the fan blade conforms to aerodynamics and the wind force is greater.

[0014] Further setting: The area of the windward side is smaller than that of the leeward side. With this setting, the wind speed on the leeward side is greater and the overall wind force is greater.

[0015] In summary, for the industrial ceiling fan described above, by providing a mounting base plate that can connect the fan blade and the main body of the ceiling fan into a whole, the stable connection of the fan is realized, and the structure is relatively ingenious and simple, achieving the beneficial effects of stable installation, convenient installation, convenient production, cost reduction and efficiency improvement.
