| titleOfInvention | A LED display screen with dustproof and waterproof effect |
| abstract | The utility model discloses an LED display screen with dustproof and waterproof effects, wherein a sealing plate is arranged behind a protective screen, a circuit substrate is arranged between the protective screen and the sealing plate, an LED lamp is electrically connected to the circuit substrate, and the circuit substrate is electrically connected to the circuit substrate. The rear side of the mounting frame is evenly fixed with a heat dissipation fin, and the rear side of the mounting frame is fixed with a mounting back plate, and the space between the mounting back plate and the sealing plate constitutes a heat dissipation cavity, and the water storage tank is communicated with the heat dissipation cavity; the dust removal mechanism includes: sliding installation The sliding bar on the front side of the installation frame, the cleaning cotton fixed on the inner side of the sliding bar, the water spray pipeline opened on the inner side of the sliding bar, and the driving mechanism connected with the sliding bar power; The water spray port is connected with the water spray pipe and the water spray port. The utility model can effectively prevent dust and water and ensure the normal operation of the LED lamp, can clean the protective screen efficiently and quickly, and can effectively cool the circuit board. |
