A water pump 4 is fixedly installed on the left side of the connecting seat 3. A spraying assembly 5 is provided on the front of the placement plate 2. The spraying assembly 5 includes a support plate 501. A spray head 502 is rotatably connected through and above the support plate 501. A bearing is provided between the spray head 502 and the support plate 501. A pipeline is connected between the spray head 502 and the water pump 4. A flexible hose is provided between the spray head 502 and the water pump 4. A gear 503 is fixedly connected to the outer surface of the spray head 502. A rack 504 meshes with the rear of the gear 503. The rack 504 is slidably connected to the front of the placement plate 2. A slide rail is provided on the placement plate 2 for the rack 504 to slide left and right. A pusher 505 is rotatably connected above the rack 504. A turntable 506 is rotatably connected below the pusher 505. The connection point between the spray assembly 5 and the turntable 506 is eccentrically set on the turntable 506. A rotating shaft 507 is fixedly connected to the bottom of the turntable 506. The rotating shaft 507 is connected to the center of the bottom of the turntable 506. A motor 508 is fixedly connected to the front of the placement plate 2. The output end of the motor 508 is fixedly connected to the lower end of the rotating shaft 507 through a coupling. The motor 508 is electrically connected to the water pump 4. A circuit is provided between the motor 508 and the water pump 4 so that the motor 508 and the water pump 4 can start and operate simultaneously after being powered on. The spray assembly 5 also includes a shaft bracket 509. The shaft bracket 509 is rotatably connected to the outer surface of the rotating shaft 507. The shaft bracket 509 is fixedly connected to the front of the placement plate 2. A storage tank 6 is threadedly connected to the top of the connecting seat 3. The lower end of the storage tank 6 is threaded for screwing into the connecting seat 3. A baffle 7 is provided on the outer surface of the storage tank 6. The storage tank 6 can communicate with the water pump 4 through the connecting seat 3. The baffle 7 is fixedly connected to the front of the placement plate 2.
[0024] In actual use, the disinfectant in the storage tank 6 will be poured into the connecting seat 3 under the action of gravity. When it is necessary to disinfect the elevator car, the water pump 4 is started. The water pump 4 will draw the disinfectant in the connecting seat 3 and deliver it to the spray head 502 through the hose, so that the disinfectant is sprayed out. At this time, the rotation of the motor 508 drives the rotating shaft 507 to rotate. The rotation of the rotating shaft 507 will drive the turntable 506 to rotate. The rotation of the turntable 506 will drive the push bar 505 to push and pull the rack 504 back and forth to slide left and right. The rack 504 will continuously move the gear 503, causing the spray head 502 to swing left and right, thereby expanding the spraying area.
[0025] Example 2
[0026] See Figures 1-4Based on Embodiment 1, a diffusion assembly 8 is provided below the spray head 502. The spray head 502 specifically consists of a hook-shaped tube and a nozzle. The diffusion assembly 8 includes a fan 801, which blows air by rotating. A rotating rod is fixedly connected to the rear end of the fan 801 and is rotatably connected to the front of the placement plate 2. A rotating column 803 is rotatably connected to the left side of the rotating rod via a transmission belt 802. A transmission wheel for transmission by the transmission belt 802 is provided on the rotating rod and the rotating column 803. The rotating column 803 is rotatably connected to the front of the placement plate 2, and a differential gear is provided on the front of the rotating column 803. Component 9, the differential assembly 9 includes a crown gear 901, which is fixedly connected to the outer surface of the rotating shaft 507. A bevel gear 902 meshes above the crown gear 901 and is fixedly connected to the front end of the rotating column 803. The rotation of the crown gear 901 can drive the bevel gear 902 to rotate the rotating column 803. The diffuser assembly 8 also includes a baffle 804, which is specifically a metal mesh cover. The baffle 804 is disposed on the outer surface of the fan 801. An opening for accommodating the transmission belt 802 is provided on the left side of the baffle 804. The baffle 804 is fixedly connected to the front of the placement plate 2.
[0027] In practical use, the rotating shaft 507 rotates, which in turn drives the crown gear 901 to rotate. The rotation of the crown gear 901 drives the bevel gear 902 to rotate the rotating column 803. The rotation of the rotating column 803 drives the transmission wheel to drive the transmission belt 802. The transmission belt 802 drives the rotating rod to rotate, which in turn drives the fan 801 to rotate inside the baffle 804. The rotation of the fan 801 blows air, which disperses the disinfectant sprayed by the spray head 502, thus achieving the effect of spreading the disinfectant and facilitating comprehensive disinfection of the elevator car.
