[0022] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 3 As shown, the present invention discloses an industrial ceiling fan 100, comprising a mounting base 1, an extension rod 2, a fan hub, a motor 4, and fan blades 5. The fan hub, motor 4, and fan blades 5 are fixed in place by the mounting base 1 and the extension rod 2. The fan hub and fan blades 5 are further driven by the motor 4 to rotate, thereby achieving ventilation in the space and cooling of people.

[0024] Specifically, the mounting base 1 is mounted on the roof or beam via bolts, the upper end of the extension rod 2 is mounted on the mounting base 1 via fasteners, and the lower end is connected to the motor 4 via fasteners. Optionally, the length of the extension rod 2 can be set to be adjustable to facilitate adjustment of the working height of the industrial ceiling fan 100, effectively improving the practicality of the industrial ceiling fan 100.

[0025] The fan hub and the motor 4 are sequentially mounted on the end of the extension rod 2 from top to bottom, and the fan hub is drivingly connected to the motor 4. Typically, the fan hub has an annular locking portion and a protrusion extending radially from the outer peripheral edge of the locking portion. The protrusion is provided in multiple portions, and the multiple protrusions are arranged at equal angles to connect to the fan blades 5.

[0026] A controller 6 is also mounted on the side of the extension rod 2 near the fan hub. The controller 6 is configured to drive the motor 4 to rotate the fan blades 5. Specifically, two connecting plates 7 are mounted on the extension rod 2, one above the other. Each connecting plate 7 is provided with a connecting piece (not shown). The controller 6 is mounted and matched with the connecting piece to be fixed to the extension rod 2.

[0027] Optionally, there is a first distance between the controller 6 and the mounting base 1, and a second distance between the controller 6 and the fan hub, and the first distance is 3 to 4 times the second distance. In this case, the wires between the controller 6 and the mounting base 1 and between the controller 6 and the motor 4 are the shortest. Of course, the multiple relationship between the first distance and the second distance can be set according to actual needs and is not limited here.

[0028] like Figures 4 to 6 and combined Figure 2 and Figure 3As shown, the connecting plate 7 is provided with a first assembly hole 71, and the extension rod 2 is provided with a second assembly hole 21 corresponding to the first assembly hole 71, and the connecting plate 7 and the extension rod 2 are locked and fixed by a fastener passing through the first assembly hole 71 and the second assembly hole 21. Optionally, the fastener is a screw, and the second assembly hole 21 is a screw hole. Of course, in other embodiments, the connecting plate 7 and the extension rod 2 can also be assembled and fixed by a buckle structure or other structure, as long as the fixed connection of the connecting plate 7 and the extension rod 2 can be realized, which is not limited here.

[0029] The top and bottom of the controller 6 are provided with protruding mounting portions 61, the mounting portions 61 are provided with mounting holes 62, the connecting piece passes through the mounting holes 62 and is fixedly connected with the mounting portions 61. Specifically, the mounting hole 62 is composed of two circular holes with different diameters, and the circular hole with a larger diameter is below and the circular hole with a smaller diameter is above, and the diameter of the connecting piece is matched with the circular hole with a smaller diameter, so that when assembling, the connecting piece can be inserted into the circular hole with a larger diameter first, and then vertically clamped into the circular hole with a smaller diameter, at this time, the assembly and fixation of the connecting piece and the mounting portion 61 can be realized.

[0030] In this embodiment, the connecting piece is a screw fixedly locked on the connecting plate 7. Of course, in other embodiments, the connecting piece can also be a protruding block structure integrally formed with the connecting plate 7, preferably a columnar structure.

[0031] The controller 6 is in the shape of a cuboid, including a shell 601 and a circuit board in the shell 601. The shell 601 includes a cover 602 and a bottom box 603. In a specific embodiment, the cover 602 is provided with a touch screen custom panel, which is used to display the state parameters of the industrial ceiling fan 100, such as running speed, running time, set speed, etc. The edge of the cover 602 close to the bottom box 603 is provided with a bending portion bent inward, which is used to buckle the bottom box 603 to realize the buckling connection between the cover 602 and the bottom box 603. The circuit board is a PCB board, and a plurality of electronic components are integrated on the circuit board to control the operation of the industrial ceiling fan 100. Since the circuit board is a conventional prior art, it is not described and limited in detail here.

[0032] The mounting portions 61 extend from the upper surface and the lower surface of the bottom box 603, and the top of the bottom box 603 is provided with two mounting portions 61, and the bottom is also provided with two mounting portions 61, so that the four corners of the controller 6 can be fixed, increasing the connection stability between the controller 6 and the extension rod 2.

[0033] The extension rod 2 is a hollow square tube, the connecting plate 7 is arranged perpendicularly to the extension rod 2, and both ends of the connecting plate 7 extend beyond the extension rod 2, and the connecting pieces are arranged at both ends of the connecting plate 7 and outside the extension rod 2. In this way, the controller 6 can be fixed without improving the structure of the extension rod 2.

[0034] Of course, because both ends of the connecting plate 7 extend beyond the extension rod 2, the two sides of the bottom box 603 are suspended, that is, not in contact with the extension rod 2, at this time, the space on the side of the bottom box 603 facing the extension rod 2 can be utilized, for example, a heat dissipation hole is arranged on the two sides of the bottom box 603 to enhance the heat dissipation effect of the controller 6, or a fixing structure is arranged on the two sides of the bottom box 603 to connect the extension rod 2 and the bottom box 603, further enhancing the connection stability between the controller 6 and the extension rod 2.

[0035] The bottom of the extension rod 2 is fixedly connected with the fan hub through an adapter 22, the adapter 22 is arranged in a U shape and in surface contact with the extension rod 2, thereby enhancing the connection stability between the extension rod 2 and the adapter 22.

[0036] The extension rod 2 is hollow, the side of the controller 6 facing the extension rod 2 is provided with a wire inlet hole, and a wire outlet hole 23 is arranged on the extension rod 2 correspondingly, a power line (not shown) enters the extension rod 2 from the mounting seat 1, passes out from the wire outlet hole 23, and enters the controller 6 from the wire inlet hole, thereby supplying power to the controller 6.

[0037] Of course, in order to ensure the appearance of the extension rod 2 and the controller 6, the wire outlet hole 23 can not be arranged on the extension rod 2, and the wire can directly pass out from the bottom of the extension rod 2, at this time, the wire inlet hole can be arranged on the bottom of the controller 6.

[0038] In summary, the industrial ceiling fan 100 of the utility model installs the controller 6 on the side of the extension rod 2 close to the fan hub, and installs two connecting plates 7 distributed upward and downward on the extension rod 2, and the connecting pieces are arranged on each connecting plate 7, thereby fixing the controller 6 on the extension rod 2 through the cooperation of the controller 6 and the connecting pieces, saving the wire between the controller 6 and the mounting seat 1, and not affecting the appearance of the wall.

[0039] The above embodiments are only used to illustrate the technical scheme of the utility model and not limit it, although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical scheme of the utility model can be modified or replaced equivalently without departing from the spirit and scope of the technical scheme of the utility model.
