Problems solved by technology

The projector uses a high-power light source as the projection light source, so it generates a lot of heat. In order to protect the components from high temperature damage, a large air inlet is generally opened, and a fan or other device is used to force the air in to improve the heat dissipation of the projector. Efficiency, but it is very easy to bring dust in the outside air into the projector. If the dust enters the optical channel, it will seriously affect the imaging quality of the projector, increase the failure rate, and reduce the service life.
[0003] The color wheel is an accessory inside the projector, and it is the closest device to the entrance of the light channel of the projector, so the dust accumulated on the color wheel can easily enter the light channel when the projector is started, polluting the optical system

Embodiment

[0013] Example: see attached figure 1 As shown, a projector color wheel dust cover includes an aluminum alloy cover body 1 that can partially cover the color wheel. The alloy cover body 1 is provided with positioning screw holes 4, which are connected with the internal positioning of the projector through screws.

[0014] The aluminum alloy cover body 1 is provided with a plurality of aluminum alloy cooling fins 5 , the aluminum alloy cooling fins 5 have hollow cavities, and the hollow cavities of the aluminum alloy cooling fins 5 communicate with the cover inner cavity of the aluminum alloy cover body 1 .

[0015] The surface of the aluminum alloy cover body 1 has an electrodeposited layer.

Abstract

The invention discloses a dustproof cover for a projector color wheel. The dustproof cover is characterized by comprising an aluminum alloy cover body (1) which can partially cover the color wheel, wherein the aluminum alloy cover body (1) is provided with an arc part (2) and a square part (3) which are matched with the color wheel in appearance; and the aluminum alloy cover body (1) is in positioned connection with the inside of a projector. After the dustproof cover is arranged on the color wheel for use, dust can be prevented from entering into a light channel of the projector and the pollution to a light path is avoided; and in addition, the damage to elements due to high temperature when the projector works can be avoided and effective heat dissipating can be realized.

Description

technical field [0001] The invention belongs to projector accessories, in particular to a projector color wheel dustproof cover. Background technique [0002] In recent years, projector technology has become more and more popular, and has been widely used in teaching, scientific research and entertainment and other fields. The projector uses a high-power light source as the projection light source, so it generates a lot of heat. In order to protect the components from high temperature damage, a large air inlet is generally opened, and a fan or other device is used to force the air in to improve the heat dissipation of the projector. Efficiency, but it is very easy to bring dust in the outside air into the projector. If the dust enters the optical channel, it will seriously affect the imaging quality of the projector, increase the failure rate, and reduce the service life. [0003] The color wheel is an accessory inside the projector, and it is the closest device to the entr...
