Description

Technical Field

[0001] This utility model relates to the field of projection equipment technology, and more specifically, it relates to an interactive outdoor projection all-in-one machine. Background Technology

[0002] An interactive outdoor all-in-one projector is a specialized outdoor device that integrates a motherboard, projector, and temperature control system. Its chassis is typically made of galvanized steel or stainless steel, providing excellent protection and waterproofing, enabling it to withstand complex outdoor environments. This device needs to operate outdoors for extended periods, and exposure to high temperatures can cause significant heat buildup inside. If this heat cannot be effectively dissipated in time, it will severely impact the lifespan of internal components and may even prevent the device from starting due to overheating.

[0003] Most existing interactive outdoor all-in-one projectors employ a horizontal airflow design for heat dissipation, using intake and exhaust fans at the projector's air inlets and outlets respectively. However, this horizontal cooling method has significant drawbacks: airflow is obstructed by the projector body, resulting in an incomplete airflow path, low heat exchange efficiency, and insufficient heat dissipation. Heat tends to accumulate inside the device, making it difficult to meet the cooling requirements of high-temperature outdoor environments, thus limiting the device's operational stability and lifespan.

[0004] In addition, the internal components of existing equipment are scattered, and heat dissipation components, audio components and other components lack reasonable integrated design. This not only occupies a lot of space, but also brings inconvenience to assembly and later maintenance, making it difficult to adapt to the usage requirements of compact outdoor installation scenarios. Therefore, a new interactive projection outdoor all-in-one machine is proposed. Utility Model Content

[0011] Optionally, a rotating bracket is also included; the rotating bracket is rotatably mounted on the upper housing.

[0012] This utility model has a stable overall structure. Through the vertical circulation air duct design, the heat dissipation airflow directly acts on the heat-generating components.
