Technical Field

[0001] The present invention relates to the technical field of power supply modules, and in particular to a low-loss ATX power supply module. Background Art

[0002] ATX power supply module is a power supply module that provides power to computers. It is widely used in desktop computer systems to provide stable power supply for various components of the computer (such as motherboards, hard disks, graphics cards, fans, etc.), including transformers, rectifiers, filters, power switch tubes, power control ICs, voltage regulator modules, protection cables, cooling systems, output interfaces and cables, standby power supplies and main circuit boards. Among them, the cooling system mainly dissipates the heat generated by the power supply. Most ATX power supplies are equipped with a fan to enhance heat dissipation to ensure power performance and improve equipment safety. The fan of the power supply module also needs regular maintenance and cleaning to prevent dust accumulation from affecting the heat dissipation effect. In the prior art, the fan reversal of some power supply modules has a reversal self-cleaning function, which uses the reversal of the fan to cause the dust on the blades to fall off, but the cleaning effect is not good for some dust with strong adhesion, and the scattered dust easily falls into the power supply box, affecting the performance of internal parts.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] An embodiment of a low-loss ATX power supply module of the present invention is as follows: Figures 1 to 8 As shown, it includes a main chassis 100, a cooling fan 200 and a cleaning component.

[0029] The main chassis 100 is provided with a mounting frame 110 for mounting the cooling fan 200 . The mounting frame 110 is fixed in the main chassis 100 . A protective grille 120 is provided on the main chassis 100 corresponding to the mounting position of the cooling fan 200 . The side panel of the main chassis 100 is provided with a plurality of cooling holes.

[0030] The heat dissipation fan 200 includes an intermediate compartment 210 and blades 220. The intermediate compartment 210 is rotatably mounted on the mounting frame 110 and driven to rotate by the power module in the main chassis 100, and the power module can drive the intermediate compartment 210 to rotate forward or reverse. There are multiple blades 220, which are evenly distributed around the intermediate compartment 210, and each blade 220 is inclined relative to the axial direction of the intermediate compartment 210; the blades 220 bring out the hot air in the main chassis 100 as the intermediate compartment 210 rotates forward, thereby dissipating the heat of the power module in the main chassis 100.

[0031] The cleaning assembly includes a cleaning rope 310, a collecting bin 320, a rotating wheel and a power assembly. There are multiple collecting bins 320, all of which are arranged in the middle bin 210 and are spaced apart around the middle bin 210; there are multiple rotating wheels, all of which are rotatably installed in the middle bin 210 and are parallel to the rotation axis of the middle bin 210, and each rotating wheel corresponds to a blade 220; there are multiple cleaning ropes 310, each cleaning rope 310 corresponds to a blade 220, one end of the cleaning rope 310 extends from the middle bin 210, goes around one side of the blade 220 to the end of the blade 220 away from the middle bin 210, and then extends from the blade The other side of the blade 220 extends into the middle bin 210, and the two ends of the cleaning rope 310 in the middle bin 210 are connected and sleeved on the rotating wheel; specifically, the two side surfaces of the blade 220 are the first surface and the second surface, respectively. When the middle bin 210 rotates forward, the first surface of the blade 220 is the windward side, and the second surface is the leeward side. The cleaning rope 310 wound around the first surface of the blade 220 passes through the middle bin 210 at the front side of the middle bin 210 in the forward direction of the middle bin 210, and the cleaning rope 310 wound around the second surface of the blade 220 passes through the middle bin 210 at the rear side of the middle bin 210 in the forward direction of the middle bin 210. The part of the cleaning rope 310 in the middle bin 210 passes through the collecting bin 320; the collecting bin 320 is used to clean and collect dust carried by the cleaning rope 310; the power assembly is used to drive the rotating wheel to rotate forward or reverse.

[0032] When the intermediate bin 210 rotates forward, the first side of the blade 220 is the windward side, and the second side is the leeward side. The cleaning rope 310 located on the first side is blown by the wind toward the rear side of the blade 220 in the forward rotation direction of the intermediate bin 210. At the same time, the power component drives the wheel to rotate forward, so that the side of the cleaning rope 310 located on the second side moves toward the direction close to the inside of the intermediate bin 210, so that the cleaning rope 310 carries the dust on the first side of the blade 220 and enters the intermediate bin 210 from the leeward side of the blade 220 and is collected by the collecting bin 320. When the intermediate bin 210 reverses, the second side of the blade 220 is the windward side and the first side is the leeward side. The cleaning rope 310 located on the second side is blown by the wind toward the rear side of the blade 220 in the reversal direction of the intermediate bin 210. At the same time, the power component drives the wheel to reverse, so that the side of the cleaning rope 310 located on the first side moves toward the direction close to the intermediate bin 210, so that the cleaning rope 310 carries the dust on the second side of the blade 220 and enters the intermediate bin 210 from the leeward side of the blade 220 and is collected by the collecting bin 320. By matching the moving direction of the cleaning rope 310 with the rotating direction of the blade 220, the cleaning rope 310 is moved by the wind while rotating along the blade 220, and after collecting the dust on the windward side of the blade 220, the carried dust is sent to the collection bin 320 in the intermediate bin 210 from the leeward side of the blade 220, so as to prevent the wind from blowing the dust on the cleaning rope 310 away again and escaping into the main case 100 when the cleaning rope 310 enters the intermediate bin 210.

[0033] In this embodiment, the power assembly includes a driving wheel 341, an intermediate wheel 342 and a driven wheel 343. The driving wheel 341, the intermediate wheel 342 and the driven wheel 343 are all gears, and their axes are parallel. There are multiple driven wheels 343, each of which is coaxial with a rotating wheel and fixedly connected; the intermediate wheel 342 is coaxial with the rotation axis of the intermediate warehouse 210 and meshes with multiple driven wheels 343; the driving wheel 341 is installed in the intermediate warehouse 210 and meshes with the intermediate wheel 342. The driving wheel 341 rotates and drives the driven wheel 343 to rotate through the intermediate wheel 342. Among them, a motor (not shown in the figure) for driving the driving wheel 341 to rotate is provided in the intermediate warehouse 210.

[0034] In this embodiment, a plurality of synchronous wheels 211 are arranged in the intermediate bin 210, and each synchronous wheel 211 meshes with a corresponding driven wheel 343; a vibration rod 321 is arranged on the collection bin 320, and the vibration rod 321 is parallel to the rotation axis of the intermediate bin 210, and is slidably installed on the collection bin 320 along its own axial direction, and is connected to the collection bin 320 through an elastic member (not shown in the figure). One end of the vibration rod 321 extends into the collection bin 320, and the other end extends out of the collection bin 320 and abuts against the end face of the synchronous wheel 211 under the action of the elastic member; a protrusion 212 is arranged on the end face of the synchronous wheel 211, and the protrusion 212 is located at the eccentric position of the synchronous wheel 211. When the synchronous wheel 211 rotates with the driven wheel 343, the vibration rod 321 is intermittently pushed to move and push the part of the cleaning rope 310 located in the collection bin 320, so that the part of the cleaning rope 310 located in the collection bin 320 vibrates, accelerating the dust attached thereto to fall into the collection bin 320.

[0035] In this embodiment, two side surfaces of the blade 220 away from one end of the intermediate chamber 210 are respectively provided with limiting blocks 221 at both ends of the intermediate chamber 210 in the circumferential direction, so as to prevent the cleaning rope 310 from being separated from the blade 220 .

[0036] In this embodiment, a plurality of cleaning holes 213 are provided on the middle bin 210, and each cleaning hole 213 is connected to a collecting bin 320 for cleaning the collecting bin 320. Specifically, when the cooling fan 200 is working normally, the cleaning hole 213 is blocked, and after a period of use, the suction head of the existing suction device can be extended from the cleaning hole 213 into the collecting bin 320 to suck the dust in the collecting bin 320.

[0037] In this embodiment, the cleaning rope 310 is provided with flexible bristles distributed along its length direction, and the flexible bristles can absorb dust.

[0038] In this embodiment, brushes (not shown in the figure) are provided at the inlet and outlet of the cleaning rope 310 in the collecting bin 320 for cleaning the cleaning rope 310 and preventing dust in the collecting bin 320 from flowing out.

[0039] When the ATX low-loss power supply module of the present invention is in normal use, the cooling fan 200 starts to rotate forward synchronously with the power supply module in the main box 100 to dissipate heat and cool the power supply module, and the motor used to drive the driving wheel 341 to rotate is not started. After running for a period of time, the cooling fan 200 is started to reverse. When the cooling fan 200 reverses, the second side of the blade 220 is the windward side, and the first side is the leeward side. The cleaning rope 310 located on the second side is blown by the wind to the rear side of the blade 220 in the reverse direction of the intermediate bin 210. At the same time, the motor drives the rotating wheel to reverse through the driving wheel 341, the intermediate wheel 342 and the driven wheel 343, so that the cleaning rope 310 on the side of the first side moves toward the direction close to the inside of the intermediate bin 210, so that the cleaning rope 310 carries the dust on the second side of the blade 220 and enters the intermediate bin 210 from the leeward side of the blade 220, and is collected by the collection bin 320. The heat dissipation fan 200 rotates forward during normal operation, with the first side being the windward side and the second side being the leeward side. Dust easily adheres to the first side. When cleaning the heat dissipation fan 200, the heat dissipation fan 200 is reversed, with the first side being the leeward side, and the cleaning rope 310 located on the side of the first side moving toward the direction close to the middle bin 210. This can not only quickly deliver the dust cleaned from the first side by the cleaning rope 310 to the collection bin 320, but also reduce the amount of dust that is blown away by the wind when the cleaning rope 310 on the second side enters the collection bin 320. Similarly, if the heat dissipation fan 200 rotates backward during normal operation, when cleaning the heat dissipation fan 200, the heat dissipation fan 200 is rotated forward, and the motor drives the rotating wheel to rotate forward. In some other embodiments, when cleaning the heat dissipation fan 200, the heat dissipation fan 200 can also be reversed and then rotated forward, and the rotating wheel can be reversed and then rotated forward, so as to clean both sides of the blade 220. When the cleaning rope 310 enters the collection bin 320, the synchronous wheel 211 rotates with the driven wheel 343, intermittently pushing the vibration rod 321 to hit the cleaning rope 310, causing the dust on the cleaning rope 310 to fall off. After accumulating for a period of time, the collection bin 320 can be cleaned using an external exhaust device.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
