Description

Vehicle-mounted shoe dust removal device and its usage method Technical Field

[0001] This invention relates to the field of vehicles, and more particularly to a vehicle-mounted shoe dust removal device and its usage method. Background Technology

[0002] When riding in a vehicle, passengers bring in mud, dust, and other dirt through the soles and uppers of their shoes. If this dirt is not cleaned in time, it can contaminate the floor, carpet, and other parts of the vehicle. Passengers may try to improve the environment by changing their shoes, but this can be awkward and carries the risk of spreading athlete's foot. In addition, changing shoes can produce odors, be cumbersome, and leave passengers with nowhere to put their shoes. All of these factors can affect the comfort of the ride and the overall environment of the vehicle.

[0003] In existing technologies, simply cleaning the car floor and carpet regularly is insufficient to completely remove long-term accumulated dirt and dust. Residual dirt can also produce odors, polluting the interior environment. Furthermore, passengers cannot clean their shoes before each use. Improving the car's interior environment by changing shoes presents challenges such as embarrassment, the risk of spreading athlete's foot, unpleasant odors, cumbersome procedures, and a lack of storage space for shoes, all of which negatively impact passenger comfort and the overall car environment. Summary of the Invention
