Problems solved by technology

However, this lens cover can only block part of the dust, and the finer dust particles will still invade the inside of the lens, so the dustproof effect is poor.
Also, since the projector is at a high position, it is very inconvenient to remove the lens cover
The lens cover is easy to fall off. When the lens cover is dropped, the lens is still not protected from dust
