[0041] Wherever possible, the various aspects and features described and illustrated in this specification may be applied individually, and these individual aspects may serve as the subject matter of a divisional application.
[0042] This utility model provides a fan controller and a fan including the above-mentioned fan controller.
[0043] Figures 1 to 6 An embodiment of a fan controller provided by this utility model is shown. The fan controller includes a control component 1, a wiring frame 2, and a housing 3.
[0044] The housing 3 includes an end cap 31 and a cover plate 32. A wiring cavity is formed on the end cap 31, with a mounting port 311 on the outer side and a wiring through hole 312 on the inner side. The cover plate 32 is detachably and sealingly connected to the mounting port 311. The cover plate 32 closes the mounting port 311 to prevent water from the external environment from entering the end cap 31 through the mounting port 311.
[0045] The control component 1 includes a first circuit board 11 and a terminal block 12. The first circuit board 11 is disposed inside the end cover 31, and the terminal block 12 is connected to the first circuit board 11. There is at least one terminal block 12. Other electronic components are also connected to the first circuit board 11. The control component 1 is used to control the operation of the fan.
[0046] The wiring frame 2 is fixedly connected to the first circuit board 11 and corresponds to the wiring through hole 312 of the end cover 31. The wiring terminals 12 are integrated inside the wiring frame 2, and the wiring frame 2 surrounds a plurality of wiring terminals 12.
[0047] The wiring frame 2 has a potting layer (not shown in the figure) inside, which seals the connection between the wiring terminal 12 and the first circuit board 11, thus providing waterproofing. The wiring terminal 12 is higher than the wiring frame 2 and is used to connect wires.
[0048] The cover plate 32 can be fixedly connected to the end cover 31 by snap-fit, fastener connection or other detachable connection methods, and closes the mounting port 311. After opening the cover plate 32, external wires can be connected to the terminal block 12 through the wiring cavity.
[0049] In one specific implementation, such as Figure 2 As shown, the housing 3 is constructed as a cap-shaped structure, with an inner cavity formed on its inner side to accommodate the control assembly 1. The mounting port 311 is located on top of the end cap 31. The housing 3 covers the top and sides of the control assembly 1.
[0050] The outer casing 3 can be fixedly connected to the fan body to isolate and protect the control component 1 from the external environment. A flange 310 can be provided on the edge of the end cover 31, and the flange 310 can be fixedly connected to the fan by fasteners.
[0051] Those skilled in the art will understand that the fan controller can be installed together with the fan or can be set up independently of the fan. When set up independently, the end cover 31 of the fan controller needs to be fixedly connected to another base.
[0052] In some implementations, such as Figure 2As shown, a sealing ring 33 is provided between the edge of the cover plate 32 and the mounting port 311, which can seal the gap between the edge of the cover plate 32 and the mounting port 311, prevent external moisture from entering the mounting port 311, and protect the control component 1 inside the end cover 31.
[0053] like Figure 4 In one specific embodiment shown, an annular groove 319 may be provided on the edge of the mounting port 311. The sealing ring 33 is embedded in the annular groove 319 to achieve installation positioning.
[0054] In another embodiment, the sealing ring 33 may also be provided on the cover plate 32.
[0055] Furthermore, the edge of the mounting port 311 forms a raised edge that is higher than the sealing ring 33, and the inner side of the cover plate 32 is provided with a groove that matches the raised edge. The raised edge can block water in the annular groove 319 and improve the waterproof effect.
[0056] End cap 31 and cover plate 32 can be fixedly connected by multiple screws. End cap 31 has threaded holes for mounting screws, located near the edge of mounting opening 311. Cover plate 32 has a larger area than mounting opening 311, and multiple screw holes are provided along its edge. These screw holes correspond one-to-one with the threaded holes on end cap 31, and screws are installed to fix cover plate 32 to end cap 31. Cover plate 32 covers mounting opening 311 and presses against sealing ring 33, achieving a seal on mounting opening 311.
[0057] In some implementations, such as Figure 4 As shown, a guide groove 314 is provided on the outer side of the end cap 31. The guide groove 314 extends along the edge of the mounting port 311 to the side of the end cap 31, and the guide groove 314 is lower than the edge of the mounting port 311. The guide groove 314 can quickly guide the water around the cover plate 32 to the side of the end cap 31, avoiding water accumulation around the mounting port 311.
[0058] In some implementations, such as Figure 4 and Figure 5 As shown, the wiring cavity is configured as a groove structure that is recessed from the outside to the inside of the end cover 31, and the side of the end cover 31 is provided with a wire through hole 313 that communicates with the wiring cavity.
[0059] Terminal 12 extends into the wiring cavity through wiring through hole 312, and external wires extend into the wiring cavity through wire through hole 313 and connect to terminal 12. Wiring frame 2 mates with wiring through hole 312, and the inside of wiring frame 2 is sealed with potting compound, so that the wiring cavity is separated from the inside of end cover 31, and the inside and outside of end cover 31 are thus separated from each other.
[0060] When installing or removing the fan controller, the operator opens the cover 32 and connects or disconnects wires in the wiring cavity. Even if water from the external environment enters the wiring cavity at this time, it cannot enter the inside of the end cover 31 through the wiring cavity. The wiring frame 2 and the potting layer effectively prevent water from entering the wiring through hole 312, protecting the control component 1 inside the end cover 31.
[0061] In some embodiments, the end cap 31, the wiring frame 2, and the first circuit board 11 are fixedly connected by fasteners, making installation quick and convenient.
[0062] Specifically, such as Figure 5 and Figure 6 As shown, the inner side of the end cap 31 is provided with multiple connecting posts 3110, and the ends of the multiple connecting posts 3110 are respectively provided with threaded holes. The edge of the wiring frame 2 is provided with multiple connecting holes 23, and the connecting holes 23 correspond one-to-one with the connecting posts 3110. The first circuit board 11 is provided with multiple wiring through holes corresponding to the connecting holes 23. Screws are used as fasteners. The screws pass through the wiring through holes and the corresponding connecting holes 23 of the first circuit board 11, and then are threaded to the corresponding connecting posts 3110, thereby fixing the first circuit board 11, the wiring frame 2 and the end cap 31 together.
[0063] For ease of assembly, the wiring frame 2 and end cap 31 are positioned and connected. For example... Figure 5 and Figure 6 As shown, the inner ring shape of the wiring frame 2 is adapted to the shape of the wiring through hole 312. The top edge of the inner ring of the wiring frame 2 forms a raised positioning edge 22, which can be inserted into the wiring through hole 312 of the end cover 31 to install and position the end cover 31 and the wiring frame 2.
[0064] Furthermore, a waterproof groove 21 can be provided on the top of the wiring frame 2. The waterproof groove 21 has a ring structure and surrounds the positioning edge 22, which can improve the waterproof capability of the wiring frame 2. The bottom of the wiring frame 2 is flat and fits against the surface of the first circuit board 11 to prevent the sealant injected into the wiring frame 2 from flowing out through the gaps.
[0065] In some implementations, such as Figure 1 , Figure 2 and Figure 4 As shown, in order to increase the heat dissipation effect of the controller, an air duct cover 34 is connected to the outside of the end cover 31, and a heat dissipation air duct 35 is formed between the air duct cover 34 and the end cover 31. A vent 315 communicating with the heat dissipation air duct 35 is formed on the end cover 31. The heat dissipation air duct 35 is located on the outside of the end cover 31.
[0066] Airflow from the environment can enter the heat dissipation duct 35 and carry away the heat from the end cover 31. The heat-generating electronic components of the control assembly 1 can be arranged close to the heat dissipation duct 35, which helps to accelerate the heat dissipation speed.
[0067] The heat dissipation duct 35 increases the area through which airflow passes over the end cover 31. The heat dissipation duct 35 can be configured with a streamlined structure, which is conducive to rapid airflow. The outer side of the duct cover 34 can also be configured with a streamlined structure.
[0068] The connection methods between the air duct cover 34 and the end cap 31 include, but are not limited to, snap-fit, adhesive, screw connection, and integral molding.
[0069] Vent 315 is located at the edge of end cover 31, and heat dissipation duct 35 extends from vent 315 to the top of end cover 31. An opening connecting the heat dissipation duct 35 is formed between the duct cover 34 and the top of end cover 31. Airflow enters the heat dissipation duct 35 from vent 315 and then flows to the opening at the top of end cover 31, or airflow enters the heat dissipation duct 35 from the opening at the top of end cover 31 and then flows to vent 315.
[0070] Specifically, the vent 315 is located on the flange 310 of the end cover 31, and the edge of the vent 315 extends from the flange 310 to the outside of the end cover 31 to form an extension edge 317. The air duct cover 34 is fixedly connected to the extension edge 317.
[0071] Furthermore, multiple spaced heat dissipation fins 316 are formed on the end cover 31. These fins are located within the heat dissipation duct 35 and extend from the vent 315 to the top of the end cover 31, meaning they extend from one end of the heat dissipation duct 35 to the other. The heat dissipation fins 316 increase the contact area between the end cover 31 and the airflow, which helps to accelerate the heat dissipation speed of the end cover 31.
[0072] In some implementations, such as Figure 3 As shown, the control component 1 also includes a second circuit board 13, on which an indicator light 14 for displaying the operating status of the controller is provided.
[0073] A light guide or a viewing window can be provided on the end cover 31, and the indicator light 14 can be placed at the bottom of the light guide or the viewing window, so that the user can easily observe the indicator light 14.
[0074] Specifically, such as Figure 4 and Figure 5 As shown, the top of the end cap 31 is provided with a light-transmitting hole 318, and a light guide post 36 is installed inside the light-transmitting hole 318. The light guide post 36 and the light-transmitting hole 318 are sealed together to prevent water from the external environment from entering the light-transmitting hole 318.
[0075] In some embodiments, the first circuit board 11 is a driver board used to control the fan's driver. The second circuit board 13 is a control board used to control the indicator light 14 and to implement other control functions.
[0076] Reference Figure 2and Figure 3 From a visual perspective, the first circuit board 11 is horizontally positioned inside the end cover 31, and the second circuit board 13 is vertically positioned inside the end cover 31, connected above the first circuit board 11. The indicator light 14 is located on top of the second circuit board 13. The light guide post 36 is located at the top of the end cover 31, and the indicator light 14 is located at the bottom of the light guide post 36, resulting in a compact overall structure. The user can observe the light of the indicator light 14 through the light guide post 36.
[0077] The fan controller provided by this utility model protects the control component 1 inside the end cover 31. The wiring terminals 12 of the control component 1 are integrated in the wiring frame 2 to form a modular structure and extend into the wiring cavity on the end cover 31 through the wiring through hole 312. When wiring, the external wires are inserted into the wiring cavity through the wire hole 313 and connected to the wiring terminals 12. The wiring frame 2 is filled with sealant to form a waterproof potting layer, which separates the wiring cavity from the inside of the end cover 31 and prevents water from entering the inside of the end cover 31. After the wiring is completed, the cover plate 32 is installed on the mounting port 311. The sealing ring 33 between the cover plate 32 and the mounting port 311 can prevent water from entering the wiring cavity. The guide groove 314 around the mounting port 311 can quickly guide the water on the top of the end cover 31 to the side of the end cover 31 to prevent water accumulation around the mounting port 311. When the fan controller is working, the airflow in the environment can enter the heat dissipation air duct 35 between the end cover 31 and the air duct cover 34, carrying away the heat on the end cover 31 and dissipating heat from the control components 1 inside the end cover 31. During the operation of the fan, the operator can observe the lights of the indicator lights 14 inside through the light guide column 36 on the top of the end cover 31 to know the operating status of the fan controller.
[0078] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
