Description

FIELD OF THE INVENTION

[0001] The present invention relates to a cleaning device, and more particularly to a mop cleaning bucket with dehydrating and cleaning a mop with water by circulating and purifying sewage.

BACKGROUND OF THE INVENTION

[0002] According to the general floor cleaning method, after sweeping the floor dust, put the traditional mop into a bucket with clean water, soak it and wring it dry by hand, then wipe the floor back and forth with the mop's cleaning cloth to remove the dirt on the floor. Dirt, bacteria or dust that is difficult to remove can be removed, or special cleaning agents can also be added to the clean water to achieve different cleaning effects.

[0003] However, the conventional bucket only has the function of holding clean water. When the user puts the mop into the bucket, the user must shake the mop continuously to make the cleaning cloth shake in the clean water to wash and remove the attachments on the cleaning cloth. At the same time, the clean water in the bucket is gradually polluted into sewage. When the user wants to wash the mop again, the water in the bucket will become more and more dirty and there will be more and more dirt in the bucket. The sewage must be drained and then replaced with clean water. As a result, the water in the bucket must be changed back and forth for every floor cleaning, and the mop must be wrung out by hand to mopping the floor. Not only is the water consumption very expensive, but also the water source is not environmentally friendly.

[0004] In addition, when the existing cleaning products contain cleaning water, it is necessary to replace the cleaning water in large quantities and frequently to avoid contamination of the cleaning water to maintain and improve the efficiency of cleaning the floor or doors and windows. In this situation, frequent replacement is also required. Clean water, resulting in increased cleaning and cleaning procedures and time, waste of water sources, and in this conventional cleaning method, the parts of the environmental cleaning device that have been in contact with the dirty environment will immediately pollute the clean water. This conventional mode for thousands of years has greatly reduced the effect of cleaning the environment.

[0005] Therefore, mop cleaning buckets that use filter materials to filter sewage came into being, but the filter materials use pressure difference to generate power, so that the filter can effectively filter impurities in the water. It cannot be under no pressure or low pressure. Large-flux filtered sewage is purified to obtain clean water to wash the mop, which cannot achieve the efficiency of the cycle of sewage purification and reuse, nor can it achieve the requirements of saving water and reducing cleaning time.

[0006] In view of the foregoing circumstances, the inventor has invested a lot of time to study the relevant knowledge, compare the pros and cons, research and develop related products. After quite many experiments and tests, the "mop cleaning bucket" of this invention is eventually launched to improve the foregoing shortcomings, to meet the public use.
