Description

Technical Field

[0001] The utility model relates to the technical field of advertising machines, and particularly relates to an outdoor advertising machine with waterproof and dustproof functions. Background Art

[0002] An outdoor advertising machine is a commercial display device designed specifically for outdoor environments, used to display various advertising contents, capable of showing information under various weather conditions, providing high-quality visual and auditory enjoyment for outdoor information dissemination, and widely applied in various fields such as the CBD of commercial areas, bus stops with large passenger flows, airports, railway stations, docks, park squares, leisure places, tourist attractions, high-end communities, the catering industry, government and enterprise publicity, etc.

[0003] Although some outdoor advertising machines claim to have waterproof and dustproof functions, their actual waterproof and dustproof levels are not high. Especially for air-cooled advertising machines, there are usually multiple cooling fans installed inside air-cooled advertising machines, and ventilation openings are designed to help external cold air be inhaled into the advertising machine and hot air be discharged. To ensure the heat dissipation effect, the size and quantity of the ventilation openings need to meet the heat dissipation requirements, but this also weakens the waterproof and dustproof ability of the advertising machine. The existence of these ventilation openings and fans allows dust and moisture in the external environment to possibly enter the interior of the advertising machine through these ventilation openings. This will not only reduce the display effect and audience experience of the advertising machine, but also dust will adhere to the circuit board, affecting heat dissipation. Overheating temperature and moisture will also cause short circuits or damage to the internal components of the device, resulting in the advertising machine being unable to work properly or even damaging the device, shortening the service life of the advertising machine. Content of the Utility Model

[0004] In view of this, aiming at the deficiencies existing in the prior art, the main purpose of the utility model is to provide an outdoor advertising machine with waterproof and dustproof functions, which can effectively prevent external dust and moisture from entering the interior of the advertising machine, avoid equipment failures and performance degradation caused by dust accumulation and moisture intrusion, reduce the maintenance cost and failure rate of the advertising machine, and thus bring long-term economic benefits.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An outdoor advertising machine with waterproof and dustproof functions, comprising a chassis shell, a display module and a heat exchange mechanism.

[0009] As a preferred solution, a plurality of baffles are arranged at intervals in the diversion hood. The plurality of baffles divide the diversion hood to form a plurality of air inlet chambers, and the internal circulation fan is provided on one side of each air inlet chamber away from the internal circulation air inlet.

[0010] As a preferred solution, the outdoor advertising machine with waterproof and dustproof functions further includes a circuit board assembly arranged on the rear shell. The circuit board assembly is arranged on the side of the internal circulation fan away from the heat exchange core.
