[0020] A cleaning assembly is provided inside the bottom plate 4, and the cleaning assembly includes a brush 6 and a motor 13. The motor 13 is electrically connected to an external forward and reverse controller, and the output end of the motor 13 is controlled to rotate in the forward and reverse directions by the forward and reverse controller. The motor 13 is installed at one end inside the bottom plate 4, and a rotating rod 14 is installed at the output end of the motor 13. A push plate 15 is provided on the outer thread sleeve of one end of the rotating rod 14, and slide rods 8 are provided on both sides of the push plate 15. The side rod 7 is located on the outer side of the projection lamp body 5, and the two sides of the bottom plate 4 are provided with sliding connections with the slide rod 8. The sliding hole is used to connect the sliding rod 8 and the side rod 7. The interior of the sliding hole is hinged to the two ends of the sliding rod 8 through a movable shutter 19. The movable shutter 19 is composed of a plurality of stacked sliding blades. When the sliding rod 8 slides, the sliding hole is always closed through the movable shutter 19. A groove is provided on the side of the sliding rod 8 close to the push plate 15. The interior of the groove is elastically connected to a limit block 10 through a limit spring 9. The limit block 10 slides against one end of the push plate 15. The other end of the limit block 10 is provided with an inclined surface. The other end of the bottom plate 4 is A guide block 16 is symmetrically installed. The guide block 16 slides against the inclined surface of the other end of the limit block 10. The push plate 15 slides against the inclined surface of the other end of the limit block 10.

When cleaning dust, the motor 13 is started through the forward and reverse controller, and the motor 13 drives the rotating rod 14 to rotate, and the rotating rod 14 drives the push plate 15 to slide. When the push plate 15 slides, the push plate 15 slides against one end of the limit block 10, and the slide bar 8 is driven to slide through the limit block 10. The slide bar 8 slides on the outside of the guide rod 11 and squeezes the buffer spring 12. The slide bar 8 drives the brush 6 to slide from one end of the projection lamp body 5 to the other end through the side rod 7. After the other end of the limit block 10 slides to fit the guide block 16, the inclined surface of the other end of the limit block 10 is resisted by the guide block 16 toward the slide bar 8 The limit block 10 is disengaged from one end of the push plate 15 by the rebound force of the buffer spring 12, and the brush 6 slides back to one end from the other end of the projection lamp body 5. When it needs to be cleaned again, the motor 13 is started by the forward and reverse controller, and the motor 13 drives the rotating rod 14 to rotate in the opposite direction, and the rotating rod 14 drives the push plate 15 to slide in the opposite direction, and the other end of the push plate 15 conflicts with the inclined surface of the limit block 10, so that the limit block 10 enters the groove of the sliding rod 8, and the push plate 15 slides back to one end of the limit block 10. At the same time, the rotating rod 14 drives the fan blade 17 to rotate, and the fan blade 17 increases the air circulation at the bottom of the bottom plate 4, thereby increasing the heat dissipation effect of the projection lamp body 5.
