Embodiment Construction
[0044] Hereinafter, embodiments of the cooling system and the projection device of the present invention will be described in detail with reference to the drawings.
[0045] In the following, a liquid crystal projection device (also called a liquid crystal projector, a projector, etc.) is taken as an example for specific introduction in conjunction with the drawings, but the present invention is not limited to a liquid crystal projection device. Any suitable projection device can be applied to the cooling system of the present invention.
[0046] Such as figure 1 , figure 2 with image 3 As shown, the liquid crystal projection device of an embodiment of the present invention includes a housing 1, and the housing 1 includes an upper housing 11 and a lower housing 12, so figure 2 The liquid crystal projection device is displayed as a small thin rectangular parallelepiped shape. Obviously, the liquid crystal projection device can adopt other shapes. An operating portion 13 includin...

The invention provides a dust preventing assembly and a projecting apparatus adopting the same. The dust preventing assembly comprises a dust preventing component, a dust preventing component fixing base and a rotating mechanism; the dust preventing component consists of a dust preventing screen and a winding mechanism for winding the dust preventing screen and opening the same so as to filter air; the dust preventing component fixing base is used for accommodating the dust preventing component; the rotating mechanism is fixed on the dust preventing component fixing base and comprises a motorand a driving system, wherein the motor is jointed with the winding mechanism through the driving system so as to drive the winding mechanism to wind, and the driving mechanism is used for arranging the motor and the dust preventing component in parallel above the bottom of the dust preventing component fixing base. The height occupied by the dust preventing component is reduced, the dust preventing rotation can be automatically controlled by less components and simpler assembly, and the projecting apparatus can be miniaturized.
Description
Background technique [0001] With the rapid development of projection technology, the development and production of miniaturized, lightweight, and low-cost projection devices has increasingly become a market need, and a projection device with a dust-proof effect can play a very effective role in extending the life of the projection device. [0002] At present, some projection devices are equipped with dustproof components. The dustproof components adopt a dustproof net (such as a mesh cloth) to remove dust. The dustproof net is wound on the rotating shaft. When the dust on the dustproof net reaches a certain level, The motor is used to automatically rotate the rotating shaft of the dust-proof assembly, and the dusty mesh is rolled onto a rotating shaft, and at the same time, it drives another rotating shaft with a new mesh in advance to rotate the new mesh into the filtered air In the window, the mesh cloth can continue to play an effective filtering role until all the wound mesh c...
