Problems solved by technology

But at the same time of ventilation, dust in the air will also be brought in. If these dusts are attached to optical components, especially liquid crystal panels, it will affect the optical performance of optical components. In order to reduce the impact of dust as much as possible, the prior art often It is to install a filter screen made of silk screen or sponge on the air inlet. On the one hand, adding a filter screen will produce a certain air intake resistance. On the other hand, it will be blocked after a long time of use. The use of the projector has a serious impact, so the filter must be cleaned regularly, usually every 1-2 months, which brings great trouble to the user

Embodiment Construction

[0015] Referring to Fig. 1 and Fig. 2, the dust-proof single-lens projector of the present invention includes a housing 1 and a light engine lighting mechanism 2, a light engine imaging mechanism 3, a circuit board 4, a light source 5, a lamp 6, and a power supply arranged in the housing. 7. An axial flow fan 8, a plurality of vortex fans 9 and a partition plate 10. The partition plate 10 separates the components arranged in the housing into two heat dissipation units, and one heat dissipation unit is a light engine heat dissipation unit, which includes a light engine lighting mechanism 2, a light engine imaging mechanism 3, a circuit board 4 and a plurality of eddy current fan9. Another heat dissipation unit is a light source heat dissipation unit, which includes a light source 5 , a lighting device 6 , a power supply 7 and an axial fan 8 . Wherein, the heat dissipation unit of the light source is provided with an air inlet and an air outlet, and is ventilated and cooled by ...

Description

technical field [0001] The invention relates to a projector, in particular to a dustproof single-lens projector. Background technique [0002] Projectors are widely used in education, business and home. A common projector generally includes a housing, a light engine, a circuit board, a light source and a corresponding heat dissipation mechanism arranged in the housing. According to the number of lenses used in the light engine, projectors can be divided into single-lens projectors and three-lens projectors. In terms of design, the white light generated by a light source is generally separated into red, green and blue three-color light, and the three-color light is modulated by three liquid crystal light valves respectively. The modulated three-color light is designed according to the single-lens or three-lens design. Different methods are used to deal with it. In a single-lens projector, the three-color light is synthesized with a color combining element and projected int...
