Detailed Implementation

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0024] See Figures 1-6This embodiment provides a high-heat-dissipation LED switching power supply, including an LED switching power supply body 1. The LED switching power supply body 1 includes a housing and internal parts and electronic components, which is the prior art. A ventilation grille 2 is provided on the top of the switching power supply body 1 for ventilation and heat dissipation. A cooling fan is provided inside the switching power supply body 1 below the ventilation grille 2. A dustproof component 3 is provided above the ventilation grille 2. The dustproof component 3 includes a metal frame 301, which is disposed on the inner surface of the ventilation grille 2. The ventilation grille 2 has a groove for placing the metal frame 301. A dustproof mesh 302 is fixedly connected to the inner surface of the metal frame 301. A pull tab 303 is fixedly connected to the top of the metal frame 301. A fixed grille 304 is hinged to the square. The fixed grille 304 has an opening for accommodating the pull piece 303. A rubber pad 305 is fixedly connected to the bottom of the fixed grille 304. The rubber pad 305 is in frictional contact with the top of the metal frame 301. When the fixed grille 304 is closed, the rubber pad 305 can squeeze the metal frame 301 to firmly place it in the groove on the ventilation grille 2. The dustproof assembly 3 also includes a fixing piece 306. The fixing piece 306 is fixedly connected to the front of the fixed grille 304. A bolt 307 is threaded through the top of the fixing piece 306. The bolt 307 is threadedly connected to the top of the LED switching power supply body 1. The top of the LED switching power supply body 1 is provided with a threaded hole that matches the bolt 307. A terminal block 4 is provided on the front of the LED switching power supply body 1.

[0025] In practical use, the above-mentioned equipment is connected to the LED switching power supply body 1 via the terminal block 4. During use, the heat inside the LED switching power supply body 1 is discharged by the cooling fan through the ventilation grille 2. The dustproof net 302 plays a role in preventing dust on the ventilation grille 2. When it is necessary to clean or replace the dustproof net 302, first loosen the bolt 307 to remove the fixing plate 306 from the LED switching power supply body 1, then flip the fixing grille 304 upward. At this time, hold the pull plate 303 to lift the metal frame 301 upward, thereby removing the metal frame 301 and the dustproof net 302 inside from the ventilation grille 2 for cleaning or replacement. Example

[0026] See Figures 1-6Based on Embodiment 1, a storage component 5 is provided on the right side of the LED switching power supply body 1. The storage component 5 includes a storage box 501, which is open at the top. The storage box 501 is fixedly connected to the right side of the LED switching power supply body 1. A spring 502 is fixedly connected to the bottom of the inner surface of the storage box 501. Under normal conditions, the spring 502 will apply elastic force to push the placement plate 503 upward. The placement plate 503 is fixedly connected to the upper end of the spring 502. There are four springs 502, which are respectively set under the placement plate 503. The four corners of the square are connected to the inner surface of the storage box 501 by a sliding plate 503. The plate 503 can slide up and down on the inner surface of the storage box 501. A cleaning brush 504 is provided above the plate 503. The cleaning brush 504 includes a brush rod and a brush head. A sealing component 6 is provided above the storage component 5. The sealing component 6 includes a cover plate 601. The cover plate 601 is fixedly connected to the right side of the fixed grid 304. The sealing component 6 also includes two pressing plates 602. The pressing plates 602 are fixedly connected to the upper part of the plate 503.

[0027] In practical use, when the fixed grille 304 flips upward, it will cause the cover plate 601 to flip upward as well. The cover plate 601 will move away from the storage box 501, and at the same time, the cover plate 601 will remove its support for the pressing plate 602. At this time, the spring 502 will apply elastic force to push the placement plate 503 upward. The placement plate 503 will drive the pressing plate 602 to protrude above the storage box 501. At the same time, the placement plate 503 will drive the cleaning brush 504 to rise together, making it easy to remove the cleaning brush 504 from the storage box 501. The dust screen 302 can be cleaned by taking out the cleaning brush 504.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
