[0034] Example 1

[0035] Reference Figures 1 to 3 This utility model provides an embodiment of an external fan controller, including a controller body 1. The surface of the controller body 1 is frosted to enhance its anti-slip properties. The internal space is reasonably arranged to accommodate electronic components and provide heat dissipation channels. Limiting rods 1 and 2 are fixedly connected to the left and right ends of the rear side of the controller body 1. The surface of the limiting rods 1 and 2 is smooth and threaded holes are provided at both ends. They are fixed to the controller body 1 by screws to ensure stable installation. Multiple slidable wiring mechanisms are connected to the outside of the limiting rods 1 and 2. Dustproof shells 13 are fixedly connected to the left and right sides of the controller body 1 by screws. The transparent design facilitates observation of the internal state and can effectively prevent dust, water vapor and other pollutants from entering the controller. A cleaning mechanism is slidably connected inside the dustproof shell 13. The cleaning mechanism includes a cleaning brush 16. The cleaning brush 16 is slidably connected to the limiting rod 2 15 through the through hole opened inside and can move up and down along the limiting rod 2 15.

[0036] Its outer side is attached to the inner wall of the dustproof shell 13. The dust on the surface of the controller body 1 can be cleaned by manually pushing and pulling, keeping the heat dissipation holes unobstructed. Limit rods 15 are fixedly connected to the front and rear sides of the interior of the dustproof shell 13. The interior of the cleaning brush plate 16 is slidably connected to the exterior of the limit rods 15. A connecting pull plate 17 is fixedly connected to the top of the exterior of the cleaning brush plate 16. A rubber sleeve 18 is fixedly connected to the exterior of the connecting pull plate 17, which is tightly fitted to the exposed end of the connecting pull plate 17 to provide a non-slip grip. The exterior of the cleaning brush plate 16 is slidably connected to the interior of the dustproof shell 13. Heat sinks 14 are fixedly connected to the left and right sides of the exterior of the controller body 1. The heat sinks 14 are in contact with the heat-generating elements inside the controller and transfer heat to the fins through heat conduction, and then dissipate heat quickly through air convection.

[0037] Example 2

[0038] like Figures 2 to 3 As shown, components identical or corresponding to those in Embodiment 1 are referenced using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is that the cable-locking mechanism includes a cable clamping plate 3. The cable clamping plate 3 has a through hole adapted to the limiting rod 2. The tolerance between the inner diameter of the through hole and the outer diameter of the limiting rod 2 is controlled within a very small range, allowing the cable clamping plate 3 to slide smoothly on the limiting rod 2, facilitating the adjustment of the cable-locking mechanism's position. Multiple elastic components are fixedly connected inside the cable clamping plate 3. These elastic components include a telescopic rod 4, which consists of inner and outer sleeves. The inner sleeve can freely extend and retract within the outer sleeve, and the fit between the two is highly precise, resulting in smooth extension and retraction without jamming. A spring 5 is sleeved on the outside of the telescopic rod 4. The elastic coefficient of the spring 5 is precisely calculated based on the thickness of the wire and the required fixing force. The design ensures that the appropriate elasticity is provided to firmly fix the wire in the wire clamping ring 6. The telescopic rod 4 is externally fixedly connected to the outside of the wire clamping plate 3. The wire clamping ring 6 is externally fixedly connected to the elastic component. The wire clamping ring 6 is designed to be circular or elliptical in shape, and the inner diameter is designed according to the outer diameter of common wires to ensure that it can adapt to wires of different thicknesses. The outside of the wire clamping ring 6 is fixedly connected to the spring 5 of the elastic component. The elasticity of the spring 5 achieves the clamping of the wire. The mounting bracket 7 is fixedly connected to the rear side of the wire clamping plate 3. The mounting bracket 7 provides sufficient space to install the adjustment component and ensures that it has sufficient strength to support the weight of the adjustment component and the force during the movement. The adjustment component is fixedly connected inside the mounting bracket 7.

[0039] The adjustment assembly includes a connecting shaft 8, which provides a rotation axis for the extension plate 9. By rotating the extension plate 9, the angle of the wire assembly mechanism can be adjusted, allowing the wire clamping ring 6 to better align with the wire, facilitating wire installation and fixation. The extension plate 9 is rotatably connected to the outside of the connecting shaft 8. By rotating and sliding the extension plate 9, the wire clamping ring 6 can be adjusted to the optimal position and angle for better wire fixation. The other end of the extension plate 9 is slidably connected to a docking plate 10. The docking plate 10 is slidably connected to the slide groove of the extension plate 9 via a slider on one side, allowing the docking plate 10 to slide back and forth on the extension plate 9, thereby achieving adjustment of the wire assembly mechanism in the length direction. When the docking plate 10 slides to the appropriate position, the locking rod 11 is operated to engage with the locking groove 12, fixing the docking plate 10 to the extension plate 9 and ensuring the stability and reliability of the wire assembly mechanism after adjustment. The upper and lower ends of the docking plate 10 are slidably connected to the locking rod 11. The outside of the connecting shaft 8 is fixedly connected to the inside of the mounting bracket 7, and the outside of the wire clamping plate 3 is slidably connected to the inside of the limiting rod 2.

[0040] Example 3

[0041] Reference Figures 2 to 4 The extension plate 9 has multiple slots 12 on its outside. The outside of the locking rod 11 engages with the outside of the slots 12. When it is necessary to fix the position of the extension plate 9, the locking rod 11 is inserted into the corresponding slot 12. The side of the locking rod 11 and the slot 12 fit tightly together. The self-locking characteristic of the trapezoidal structure is used to prevent the extension plate 9 from sliding, ensuring that the entire line mechanism is stable and reliable after adjustment. The outside of the connecting pull plate 17 is slidably connected to the inside of the dustproof shell 13, and the outside of the rubber sleeve 18 is in contact with the top of the controller body 1.

[0042] A display screen 19 is fixedly connected to the front of the controller body 1. The display screen 19 can display the real-time operating status and parameters of the fan, such as wind speed, temperature, and humidity, providing operators with intuitive operating information. Multiple buttons 20 are fixedly connected to the right front end of the display screen 19. When an operator presses a button 20, the button 20 sends an electrical signal, which is transmitted to the control circuit inside the controller to realize various control functions of the fan. Multiple indicator lights 21 are fixedly connected to the left front end of the display screen 19. The colors of the indicator lights 21 are distinguished according to different functions, such as green for normal operation, red for fault alarm, and yellow for standby. One end of a spring 5 is fixedly connected to the outside of a wire clamping ring 6, and the other end of the spring 5 is fixedly connected to the outside of a wire clamping plate 3.

[0043] Work steps

[0044] Step 1: When tidying up the wiring, remove the locking lever 11 to unlock the extension plate 9, allowing the two wire clamping plates 3 to separate. At this point, place the wiring inside the wire clamping ring 6, causing the wire clamping ring 6 to press against the telescopic rod 4, which in turn causes the spring 5 to deform, thus securing the wiring inside the wire clamping ring 6. Pull the two extension plates 9 closer to the inside of the docking plate 10, and insert the locking lever 11 to lock the locking lever 11 against the slot 12 outside the extension plate 9.

[0045] Step 2: When cleaning the heat sink 14, by pulling the connecting pull plate 17, the connecting pull plate 17 causes the cleaning brush plate 16 to slide inside the dust cover 13. As the cleaning brush plate 16 slides, it can clean both the dust cover 13 and the outside of the heat sink 14 at the same time, thereby cleaning the heat sink 14.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
