Problems solved by technology
As we all know, the projector is a delicate product, whether it is an LCD projector or a DLP projector, the requirements for the use environment are relatively high, especially the optical components are greatly affected by the particles in the air, which requires the projector to have Good dust-proof performance generally needs to keep the interior as sealed as possible. However, since the projector will generate a lot of heat during use, it is required that the projector has good heat dissipation performance, and too good sealing is not conducive to heat dissipation, so There is a contradiction
In order to solve this pair of contradictions, the existing technology is to add filter material to the air inlet of the projector to achieve the purpose of dust prevention, but the filter material needs to be cleaned regularly, and it is used in harsh environments, such as outdoors, remote villages and towns, sandstorm areas, etc. , the dust-proof system of most existing projectors is quickly blocked, causing damage to the machine; in addition, in environments with smoke and oily fume, such as karaoke halls, restaurants, etc., the smoke and oily fume will quickly pollute the optical devices, causing projection damage. The projector fails quickly, seriously restricting the market expansion of the projector

The invention is suitable for the image equipment production technology field and provides an apparatus capable of preventing from dust and fume and an overhead projector comprising the same. The apparatus capable of preventing from dust and fume comprises a shell. A first accommodation chamber and a second accommodation chamber are arranged in the shell. The first accommodation chamber is a sealed chamber. A semiconductor refrigeration sheet is arranged on a junction of the first accommodation chamber and the second accommodation chamber. A cold side and a heat side of the semiconductor refrigeration sheet respectively face the first accommodation chamber and the second accommodation chamber. At least one air inlet and a plurality of air vents are arranged on the second accommodation chamber. An external cooling fan is arranged on the each air inlet. The overhead projector employs the apparatus which can prevent from dust and fume. By using the apparatus capable of preventing from the dust and fume and the overhead projector provided in the invention, smog, oil smoke and various kinds of dusts can be effectively prevented to enter into the apparatus. Therefore, equipment can be applied in various kinds of hostile environments and a service life can be prolonged.
Description
Technical field [0001] The invention belongs to the technical field of image equipment production, and more specifically, relates to an anti-smoke device and a projector including the anti-smoke device. Background technique [0002] With the widespread application of projection technology, the application range of projectors has become wider and wider. At present, projectors are mainly used in the office and education markets. As we all know, the projector is a delicate product, whether it is an LCD projector or a DLP projector, the requirements for the use environment are relatively high, especially the optical components, which are greatly affected by particles in the air, which requires the projector to have Good dustproof performance generally needs to keep the inside sealed as much as possible. However, because the projector generates a lot of heat during use, it requires the projector to have good heat dissipation performance, and the sealing is too good to be harmful to he...
