[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1-Figure 4 As shown, the utility model provides an automatic wheelchair wheel cleaning device, comprising a cleaning pool 1, a stop plate 2 fixedly connected to the left side of the cleaning pool 1, an inclined plate 3 provided on the left side of the stop plate 2, a cleaning mechanism 5 provided on the outside of the cleaning pool 1, and a conveying mechanism 4 provided on the outside of the cleaning pool 1;

[0025] The conveying mechanism 4 includes a drive motor 406, which is arranged on the outside of the cleaning tank 1. The drive motor 406 is fixedly connected to a threaded rod 407 through an output shaft. The outer side of the threaded rod 407 is threadedly connected to an L-shaped bar 409. Two groups of symmetrically distributed cylinders 401 are arranged on the top of the L-shaped bar 409. The telescopic end of the cylinder 401 is fixedly connected to the top plate 402. The top of the top plate 402 is fixedly connected to an electric telescopic rod 403. The telescopic end of the electric telescopic rod 403 is fixedly connected to a clamping block 410.

[0026] In a further embodiment, referring to Figure 1-Figure 3The outer side of the L-shaped bar 409 is fixedly connected to a slider 408, and a slide groove 405 is provided on the outer side of the cleaning pool 1. The slide groove 405 limits the moving trajectory of the slider 408, ensuring that the slider 408 can only move left and right in the slide groove 405, and the slider 408 is slidably connected to the inner side of the slide groove 405. Under the cooperation of the slider 408 and the slide groove 405, the moving trajectory of the L-shaped plate is limited, ensuring that the L-shaped plate can only move left and right in reverse, making it convenient to move the wheelchair from the stop plate 2 to the top of the cleaning pool 1, or to take the cleaned wheelchair out from the top of the cleaning pool 1 and move it to the stop plate 2. Two groups of symmetrically distributed fixed blocks 404 are provided on the outside of the cleaning pool 1. The fixed blocks 404 are used to limit the threaded rod 407, ensuring that the threaded rod 407 can rotate between the two fixed blocks 404. The threaded rod 407 is movably connected to the opposite surfaces of the two fixed blocks 404 through bearings.

[0027] In this embodiment, the drive motor 406 drives the threaded rod 407 to rotate through the output shaft, thereby driving the fixed wheelchair to move toward the cleaning pool 1. When cleaning the wheelchair wheels, the wheelchair can be easily placed in or taken out, reducing the difficulty of cleaning and improving the cleaning efficiency.

[0028] In a further embodiment, referring to Figure 1-Figure 3 The two clamping blocks 410 are provided with opening grooves on their opposite surfaces. The two opening grooves are provided for clamping the armrests of the wheelchair from both sides, making it convenient to clean and move the wheelchair.

[0029] In this embodiment, the electric telescopic rod 403 pushes the clamping block 410 to move, clamping the wheelchair through the open slot, thereby facilitating its transport to the cleaning tank 1 for cleaning without manual pushing in or out, thereby improving practicality.

[0030] In a further embodiment, referring to Figure 1 and Figure 4, the cleaning mechanism 5 includes a water pump 501, which is fixedly connected to the outside of the cleaning pool 1. The water pump 501 is used to extract water from the cleaning pool 1 through a pumping pipe 503. The water pump 501 suction port is fixedly connected to a pumping pipe 503, and the water pump 501 discharge port is fixedly connected to an outlet pipe 502. The water extracted by the water pump 501 is discharged through the outlet pipe 502. A cleaning nozzle 506 is provided on the inside of the cleaning pool 1. The cleaning nozzle 506 is curved and is used to drive the rotation of the wheel while cleaning, and to allow the cleaned water to stay in the cleaning pool 1. The bottom end of the pumping pipe 503 passes through the cleaning nozzle 506. The outside of the washing pool 1 extends into the inside of the washing pool 1, and a filter head 504 is provided at the bottom of the water suction pipe 503. The filter head 504 is used to filter dust and dirt in the washing pool 1 to prevent dust and impurities from clogging the water pump 501 or the pipeline and the cleaning nozzle 506. The top of the outlet pipe 502 is connected to two symmetrically distributed branch pipes 505. The arrangement of four branch pipes 505 can clean four wheels through four cleaning nozzles 506 respectively. The other ends of the two branch pipes 505 pass through the outside of the washing pool 1 and extend into the inside of the washing pool 1. The branch pipes 505 are fixedly connected to the water inlet of the cleaning nozzle 506.

[0031] In this embodiment, the water pump 501 draws water from the cleaning pool 1 to clean the dust on the outside of the wheelchair wheels, thereby preventing the dust on the outside of the wheels from polluting the environment and facilitating subsequent use of the wheelchair.

[0032] The working principle of this utility model is as follows:

[0033] When cleaning the wheels of the wheelchair, the wheelchair is pushed to the top of the stop plate 2 via the inclined plate 3, and the cylinder 401 is activated to adjust the height of the clamping block 410 so that the opening groove on the outer side of the clamping block 410 is aligned with the handle of the wheelchair;

[0034] The electric telescopic rod 403 is activated, and the electric telescopic rod 403 pushes the clamping block 410 to move, and the two clamping blocks 410 clamp the wheelchair from the handles on both sides of the wheelchair;

[0035] The drive motor 406 is started, and the drive motor 406 drives the threaded rod 407 to rotate via the output shaft. The rotation of the threaded rod 407 drives the L-shaped plate to move, thereby driving the clamped wheelchair to move until the wheelchair moves above the cleaning tank 1, causing the cylinder 401 to contract, driving the wheelchair to move downward until the wheels of the wheelchair stop at an appropriate position in the cleaning tank 1;

[0036] An appropriate amount of cleaning water is added to the cleaning pool 1. The water pump 501 draws the water from the cleaning pool 1 through the water pump pipe 503 and sprays it out through the cleaning nozzle 506. The cleaning nozzle 506 cleans the wheel of the wheelchair. The curved shape of the cleaning nozzle 506 causes the wheel to rotate while cleaning, thereby comprehensively cleaning the wheel surface.

[0037] After cleaning, the cylinder 401 extends to push the wheelchair out of the cleaning tank 1, and the drive motor 406 rotates in the opposite direction to move the cleaned wheelchair above the stop plate 2 again and take it out to complete the cleaning of the wheelchair wheels.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
