Problems solved by technology

[0004] However, after the filter is used for a period of time, there will be too much dust blocking the mesh and reducing the flow of air flowing into the projection device, resulting in poor heat dissipation efficiency of the projection device

Abstract

An air filter module adapted to be used with a projection module and disposed to cover an air vent of the projection module. The air filter module includes a filter component and a cleaning unit. The cleaning unit is disposed to cover the air vent and configured to drive the filter component to have a movement so as to remove the dust on the filter component according to a cleaning-start signal. A projection device adopting the air filter module is also provided.

Description

【Technical field】 [0001] The present invention relates to a projection device, and in particular to a projection device capable of cleaning a gas filtering device in the projection device. 【Background technique】 [0002] In recent years, due to the increasing demand for high-brightness projection devices, the lamp power or system heat density in current projection devices tends to increase continuously. The bulbs, electronic components and power supply in the projection device all generate heat and generate high temperature during use, and the optical components in the projection device also generate high temperature due to the irradiation of the light beam. Therefore, in the prior art, one or more axial fans or blowers are used to cool the components inside the projection device. However, when the projection device is used in a dusty environment, the airflow generated by the axial flow fan or the blower fan will bring dust from the external environment into the projection ...
