Embodiment Construction

[0036] The present invention aims to provide a projector dustproof device and method and a projector with the dustproof device, which can more conveniently dustproof the projector.

[0037] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] Such as figure 1 As shown, it is a specific embodiment of the projector dustproof device of the present invention, which includes a grid group 1 composed of several adjacent grids 2 arranged in parallel, and each grid 2 in the grid group 1 is pivotally connected to the projector The air inlet 4 of 8 is at the air outlet (not shown), and the air outlet is similar to the air inlet 4.

[0039] In the dust-proof device for the projector in this embodiment, each grille 2 in the grille group 1 is pivotally connected to the air inlet 4 and the air outlet of the projector, so that each grille 2 in the grille group 1 can be rotated, When the projector is turned off and no...

Abstract

The invention discloses projector dust preventing device and method as well as a projector equipped with the dust preventing device and relates to the field of projection equipment. The invention aims to achieve more favorable dust preventing function. The projector comprises an air inlet and an air outlet, wherein the air inlet and the air outlet are provided with dust preventing devices; each dust preventing device comprises a grating group which comprises at least two adjacent and parallel gratings; and all the gratings in the grating group are pivoted at the air inlet and the air outlet of the projector. The projector dust preventing method comprises the following steps of: shutting down the projector; driving all the gratings in the grating group pivoted to the air inlet and the air outlet of the projector to rotate; and shutting down the air inlet and the air outlet of the projector by the rotation of all the gratings in the grating group. The projector dust preventing device and method can be used for carrying out dust prevention on the projector.

Description

technical field [0001] The invention relates to a projector, in particular to a dustproof device and method for preventing dust from entering the projector. Background technique [0002] When a projector projects an image on a projection object such as a screen, it needs to use an ultra-high pressure mercury lamp as a light source. In the working state, the ultra-high pressure mercury lamp will generate a lot of heat in the casing of the projector, and the heat will accelerate the ultra-high pressure mercury The aging of some components such as lamps shortens their lifespan, thereby increasing the cost of using the projector, so the heat should be dissipated in time. [0003] At present, a fan is generally used to dissipate heat from the projector, which requires an air inlet and an air outlet to be provided on the projector. When the projector is working, because there is forced convection, it will not accumulate too much dust at the air inlet and outlet of the projector, ...
