Description

Technical Field

[0001] This invention relates to the field of wheelchair cleaning equipment technology, and more specifically to an automatic wheelchair washing device. Background Technology

[0002] Wheelchairs are commonly used assistive mobility devices in hospitals, nursing homes, rehabilitation institutions, and for people with mobility impairments at home. During long-term use, the wheels, frame, seat, and armrests of wheelchairs are prone to accumulating dust, stains, mud, sand, and various other contaminants. In particular, dirt can easily accumulate in the gaps between the wheels and in the corners where the frame is joined, which not only affects the cleanliness of the equipment but also easily breeds bacteria, posing a hygiene hazard.

[0003] Currently, the industry's common methods for cleaning wheelchairs are manual rinsing and wiping with cloths, which have several drawbacks: First, manual cleaning requires staff to repeatedly rinse and wipe all parts of the wheelchair, which is tedious, labor-intensive, and inefficient, failing to meet the needs of large-scale, routine wheelchair cleaning. Second, manual wiping makes it difficult to clean hidden areas such as wheel crevices and frame joints, easily creating blind spots and resulting in serious stain residue problems. Third, after manual cleaning, a large amount of water stains remain on the surface and in the crevices of the wheelchair, and manual drying is difficult to achieve all-round coverage. Long-term water stains can easily lead to corrosion of the wheelchair's metal frame and aging of plastic parts. At the same time, the damp environment is very conducive to the growth of bacteria, affecting hygiene and the lifespan of the wheelchair. Fourth, the few existing wheelchair cleaning devices have limited functions, only having simple spray cleaning capabilities and lacking automatic drying structures. After cleaning, manual drying is still required, failing to achieve fully automated cleaning operations and lacking in intelligence and practicality.

[0004] Therefore, there is an urgent need to develop an automatic wheelchair washing device that can automatically complete all-round cleaning and drying, so as to realize the full automation of wheelchair cleaning process and eliminate cleaning blind spots and water stains. Summary of the Invention

[0017] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0018] This embodiment provides an automatic wheelchair washing device, such as... Figure 1 , Figure 2 As shown, it includes a cleaning box 1, a wheelchair positioning and support mechanism, an automatic spray cleaning mechanism, a hot air drying mechanism, a water circulation and filtration mechanism, and an electrical control mechanism 22.

[0019] The cleaning chamber 1 is a closed hollow chamber structure. The front of the cleaning chamber 1 is hinged to a sealed door 2 via a hinge 23. A sealing strip 24 is fixed around the inside of the sealed door 2 to achieve a sealed protection after closing and prevent sewage from splashing during the cleaning process. The cleaning chamber 1 has a sealed cleaning cavity 3 inside and a water collection cavity 4 at the bottom of the cleaning chamber 1 to collect the sewage generated during cleaning.

[0020] The wheelchair positioning and support mechanism is assembled inside the bottom side of the cleaning chamber 3. The support base plate 5 is horizontally fixed inside the cleaning chamber 3. Two sets of limiting blocks 6 are symmetrically fixed on the left and right sides of the support base plate 5. The positioning slot 7 is opened on the surface of the support base plate 5 to engage and limit the wheelchair wheels, so as to achieve precise positioning of the wheelchair after it is placed and prevent the wheelchair from shifting and shaking during the cleaning process. The surface of the support base plate 5 is evenly provided with through-holes 8. The through-holes 8 are connected to the bottom water collection chamber 4, so as to facilitate the rapid fall and collection of cleaning sewage.

[0021] The automatic spray cleaning mechanism is used to achieve all-round automatic cleaning of the wheelchair. The top spray pipe 9 is horizontally fixed to the top wall of the cleaning chamber 3, and multiple top spray heads 10 are arrayed and fixed to the bottom of the top spray pipe 9 to spray and clean the top area of ​​the wheelchair. The side spray pipes 11 are vertically fixed to the inner walls of the left and right sides of the cleaning chamber 3, and the side spray heads 12 are evenly distributed on the inner side of the side spray pipes 11 to spray and clean the side frames, armrests and seat sides of the wheelchair. The bottom spray pipe 13 is embedded in the support base plate 5, and the wheel spray nozzles 14 are arranged upward through the support base plate 5 to accurately spray and clean the wheelchair wheels and bottom gaps, achieving a thorough cleaning of the wheelchair.

[0022] The hot air drying mechanism is used to automatically dry the wheelchair after washing. The top hot air box 15 is fixed to the outer side of the top wall of the cleaning box 1, and the top air outlet 16 is embedded in the top wall of the cleaning cavity 3 and communicates with the inside of the top hot air box 15 to achieve hot air drying of the top of the wheelchair. The side hot air box 17 is fixed to the outer walls of the left and right sides of the cleaning box 1, and the side air outlet 18 is embedded in the inner wall of the cleaning cavity 3 and communicates with the inside of the side hot air box 17 to blow hot air to dry the sides and middle of the wheelchair, removing residual water stains from all directions and achieving automatic drying effect.

[0023] The water circulation filtration mechanism is installed on the bottom outside of the cleaning box 1. The two ends of the inlet pipe 20 are connected to the water collection chamber 4 and the filter box 19, respectively. The two ends of the outlet pipe 21 are connected to the filter box 19 and each spray assembly, respectively. The collected sewage can be filtered and purified and then transported to the spray mechanism for recycling, thus saving water resources.

[0024] The electrical control mechanism 22 is fixed to the outer wall of the cleaning box 1. The electrical control mechanism 22 is electrically connected to the automatic spray cleaning mechanism, the hot air drying mechanism, and the water circulation filtration mechanism, respectively, and is used to uniformly control the start and stop of each mechanism and the switching of operations, so as to realize the automated operation of the entire process of cleaning, drying and wiping.

[0025] During operation, open the sealed door and push the wheelchair to be cleaned onto the support base. The wheelchair is positioned and limited by the limit blocks and positioning slots. Then, close the sealed door. Start the equipment via the electrical control mechanism. First, the water circulation filtration mechanism and the automatic spray cleaning mechanism operate simultaneously. The top, side, and bottom spray components spray water simultaneously to thoroughly clean the top, sides, wheels, and bottom crevices of the wheelchair. The cleaning wastewater falls into the water collection chamber through the permeable holes and is filtered by the water circulation filtration mechanism for recycling. After the cleaning operation is completed, the spray mechanism stops operating, and the hot air drying mechanism starts. The top and side hot air structures spray air simultaneously to thoroughly dry the entire wheelchair with hot air, removing residual water stains from the surface and crevices, completing the automatic drying operation. After drying is complete, the equipment automatically stops. Open the door to remove the clean and dry wheelchair. The entire process is automated and requires no manual intervention.
