Embodiment Construction
[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0033] Please also refer to Figure 1 to Figure 8 and Figure 12 Now, the self-cleaning projector dust-proof net device provided by the present invention will be described. The self-cleaning projector dust-proof net device is used to prevent dust from entering the interior of the projector, including a bottom case 1 and a cooling air duct 2, and also includes a control chip for controlling the automatic cleaning process of the dust-proof net device (Fig. Invisible), dust-proof net 3, cleaning system and detection system, the dust-proof net 3 is set at the air inl...

The invention is suitable for the technical field of projecting equipment production, and particularly provides an automatic cleaning projector dust screen device and a projector. The dust screen device includes a bottom housing, a cooling air passage, a control chip, a dust screen, a cleaning system formed by an outer cleaning air passage, a fan, a motor and an air checking groove, and a detecting system including an air pressure sensor for detecting air pressure in the cooling air passage, wherein the fan and the motor are in communication connection with the control chip; the air pressure sensor issues the signal for starting the cleaning system to clean the dust screen once detecting that the air pressure in the cooling air passage is lower than the set value; and the projector includes the automatic cleaning projector dust screen device. The automatic cleaning projector dust screen device and a projector provided by the invention can automatically detect and clean the dust screen of the projector, dispenses with manual operation, and greatly improves the convenience and practicability of the projector.
Description
technical field [0001] The invention belongs to the technical field of automatic office equipment production, and more specifically relates to an automatic cleaning dust-proof net device for a projector and a projector. Background technique [0002] For projectors, dust resistance is an extremely important factor. If the dustproof effect is good, the precision components inside the projector will be well protected, and the life of the projector can be extended a lot. Therefore, the device specially used for dust-proofing of the projector is also the first thing to consider when designing. At present, the dust-proof nets used for projectors on the market are basically used for a period of time, and they need to be manually removed and cleaned before they can be used again, which is troublesome to operate and inconvenient to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatically cleanable projector...
