Problems solved by technology

[0002] Nowadays, flat panel display has become the mainstream product in the display, and it is the general trend to become the mainstream of TV in the future, but there is no strict definition in the world. Generally, this kind of display screen is thinner, with thin, light, low power consumption and low radiation. , no flicker, beneficial to human health, etc., but because large-scale flat-panel displays are generally used outdoors, an effective cooling system needs to be installed inside the display. In order to display content more clearly, the brightness of outdoor flat-panel displays is higher than that required indoors Therefore, in the heat dissipation process of the flat panel display, the exhaust pipe is installed outside the display. Since the temperature of the nozzle is lower than the internal temperature, the water in the exhaust pipe will flow back into the flat panel display, and due to the exhaust of the outdoor flat panel display The air port is large, and under the influence of external factors, dust may enter the flat-panel display from the exhaust pipe, causing the flat-panel display to malfunction

Abstract

The invention discloses an exhaust assembly of a flat-panel display. The exhaust assembly structurally comprises a display screen, a back plane, an exhaust mechanism and a stabilizing block. The rear end of the display screen is welded to the surface of the front end of the back plane, and the exhaust mechanism is arranged on the surface of the rear end of the back plane. In order to prevent dust from entering the interior of the flat-panel display, after air is exhausted when the flat-panel display operates, a rotating shaft in a rotating device drives a rotating frame to rotate, a rotating sheet connected to the rotating frame rotates along with the rotating device, gas of an exhaust pipe is exhausted, and external dust is further prevented from entering the flat-panel display. A heat dissipation device is arranged in the exhaust mechanism, so that the flat-panel display runs, hot air reacts with a condensation pipe and slides down into a drainage device connected to the lower end of a cooling device through a water receiving pipe, a baffle rotates downwards through rotation of a torsion shaft, water falls to the lower end, a blocking block is fixed to the lower end of a connecting rod connected to the middle ends of sliding shafts at the two ends, the blocking block moves downwards, and the water is discharged.
