[0017] Detailed Embodiment 1: As Figures 1-5As shown in the figure, this embodiment describes a ceiling for an elevator that is convenient for cleaning, including a ceiling 1, a rotating device 2, and a cover plate 3; the ceiling 1 includes a housing 11; the bottom end of the housing 11 is hollowed out, and a circular hole 15 is provided at the top end of the housing 11, and a dust-proof cover 16 is fixedly connected to the upper end of the circular hole 15; a two-way motor 14 is fixedly connected inside the housing 11 through a motor bracket 13; a fan blade 17 is fixedly connected to the output shaft of the two-way motor 14 near one end of the circular hole 15, and the output shaft of the two-way motor 14 far from the circular hole 15 is fixedly connected to the input end of a transmission 19; the transmission 19 is fixedly connected to the motor bracket 13 through a connecting frame 18, and a rotating shaft 110 is provided at the output end of the transmission 19; a chute 112 parallel to its central axis is provided on the outer cylindrical surface of the rotating shaft 110, and an annular groove 111 communicating with the chute 112 is also provided on the outer cylindrical surface of the rotating shaft 110;

[0018] The rotating device 2 includes a connecting cylinder 23; the connecting cylinder 23 is slidably matched with the rotating shaft 110, and a slider 24 slidably matched with the chute 112 and the annular groove 111 is provided on the inner wall of the connecting cylinder 23; a disc 22 is fixedly connected to the lower end of the connecting cylinder 23; a groove 25 is provided on the outer cylindrical surface of the disc 22; a slide plate 21 slidably matched with the groove 25 is connected in the groove 25 through a spring 26; a handle 28 is fixedly connected to the lower end of the circular plate 22;

[0019] The cover plate 3 is provided with a perforation, and the perforation is slidably matched with the slide plate 21 and the disc 22; the cover plate 3 is fixedly connected to the lower end of the housing 11. The slide plate 21, the disc 22 and the perforation are in interference fit.

[0020] A plurality of the slide plates 21 are provided. The plurality of slide plates 21 can improve the cleaning efficiency.

[0021] Brush hairs are provided on the upper end surface of the slide plate 21.

[0022] A plurality of the chutes 112 are provided. The plurality of chutes 112 facilitate the probability of the slider 24 moving from the annular groove 111 into the chute 112.

[0023] A plurality of ventilation holes 27 are provided on the slide plate 21. It is convenient for ventilation in the car.

[0024] A lamp 12 is fixedly connected to the inner top end of the housing 11.

[0025] The working principle of the present utility model is: when using this device, start the two-way motor 14, the two-way motor 14 drives the fan blade 17 to rotate, draw the outside air into the housing 11, and then discharge it into the car through the ventilation holes 27 for air replacement;

[0026] The other end of the bidirectional motor 14 drives the rotating shaft 110 to rotate through the transmission 19. When the disc 22 is embedded in the cover plate 3, the slider 24 slides with the annular groove 111. The rotation of the bidirectional motor 14 cannot drive the connecting cylinder 23 to rotate, and only air replacement is performed. When the cover plate 3 needs to be cleaned, the handle 28 is pulled downward to drive the disc 22 and the slide plate 21 to move downward, and then the connecting cylinder 23 is driven downward by the connecting cylinder 23 to move the slider 24 downward, so that the slider 24 is separated from the annular groove 111 and enters the slide groove 112. The slider 21 is separated from the perforation on the cover plate 3, and the bidirectional motor 14 is started at this time. The bidirectional motor 14 drives the rotating shaft 110 to rotate, and then drives the slider 24 and the connecting cylinder 23 to rotate through the slide groove 112. The connecting cylinder 23 drives the disc 22 and the slider 21 to rotate, so that the bristles on the upper end of the slider 21 clean the lower end surface of the cover plate 3. At the same time, when the slider 21 contacts the side wall of the car, the slider 21 slides into the groove 25 and compresses the spring 26. When the slider 21 reaches the corner of the cover plate 3, it pops out under the elastic force of the spring 26.
