ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to cleaning apparatus and, more particularly, to a shoe-base cleaning apparatus with jack means for replenish of cleaning solution.
2. Description of Related Art
When cleaning the floor, people may move the wiper with the legs over the floor. It is uncomfortable to step the foot on the wet, cold wiper. It is also inconvenient to move the wiper over the floor with the foot or the toes, or to apply cleaning solution or water wax to the wiper during cleaning.
Therefore, it is desirable to provide a cleaning apparatus that eliminates the aforementioned problems.
SUMMARY OF THE INVENTION
The main object of the present invention is to provide a shoe-base cleaning apparatus, which can be put on the foot for cleaning the floor conveniently. Another object of the present invention is to provide a shoe-base cleaning apparatus, which can be conveniently filled with cleaning solution for cleaning.
To achieve the aforesaid objects, the shoe-base cleaning apparatus of the present invention comprises a unit bottom and an upper. The unit bottom comprises a sock, a sidewall, a wiper, and at least one jack. The sidewall is connected to the peripheral area of the sock, defining with the sock a receiving chamber. The wiper is mounted in the receiving chamber. The at least one jack is respectively mounted in the side wall for the filling of cleaning solution into the wiper, each formed of a hollow shell and a hollow stud press-fitted into the hollow shell. In order to protect the upper against water, the sock and the sidewall are made of waterproof cloth. The waterproof cloth and its stitching are of the known art not within the scope of the invention. For the filling of cleaning solution into the wiper in the receiving chamber, the sidewall is provided with at least one through hole to which a respective jack is fastened. Through the jack in each through hole of the sidewall, clean water, soap water, liquid detergent, solvent, water wax, and etc., is filled into the wiper inside the receiving chamber. Each jack may be provided with a one-way valve to prevent leakage. The wiper of the shoe-base cleaning apparatus is similar to the structure of the insole or out sole of a regular shoe. It can be made of foamed material, sponge, cotton cloths, non-woven cloths, tissues, or other fabrics. Regular wiper materials can be used for the wiper of the shoe-base cleaning apparatus. When cleaning solution or the like is filled into one jack of the shoe-base cleaning apparatus, the wiper immediately absorbs it. For easy washing, the wiper can be made detachable. In order to provide a wide wiping area, the wiper is made having a wiper body detachably mounted in the receiving chamber, and a wiper head formed integral with the wiper body and extended out of the unit bottom.
Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
