Description

Method for cleaning flat mop Technical field

The embodiment of the invention relates to a method for cleaning a flat mop.

Background technique

In the prior art, there are three ways of dewatering a flat mop by foot squeeze type dehydration. A foot squeezing device is provided on the mop bucket. The foot squeezing device includes a water squeezing basket and a hinge The pedals on the upper part of the mop bucket and opposite to the squeeze basket, the pedals and the squeeze basket form a squeeze space. When dehydrating, you need to remove the mop on the mop board of the flat mop first, and place the mop in the squeeze space. , And then step on the pedal to shrink the squeezing space to squeeze the water on the mop dry. This type of dewatering method requires the design of a foot-squeezing device with a complex structure, and the cost is relatively high; when squeezing water, the mop needs to be removed first, and the foot needs to be stepped on, which is troublesome.

The second method is centrifugal spin dehydration, which uses a hand-pressed rotary mop rod. When dehydrating, you need to bend both ends of the mop plate of the flat mop and place it in the dehydration area of the mop bucket. Press the mop rod down to make The mop plate of the flat mop is centrifuged to spin dehydration. This type of dewatering method needs to design the mop plate of the flat mop into a bendable structure, the structure is relatively complicated, and it needs to be matched with the hand-pressed rotary mop rod, and the cost is high.

The third method is hand-push squeeze dehydration, such as Chinese invention patents ZL200720192814.5, ZL201320019718.6, ZL201420624020.1, etc., which include a mop rod, a flat mop board movably connected to the mop rod, and a flat mop board movably connected to the mop rod. There is a water squeezing mechanism, through the relative squeezing movement between the water squeezing mechanism and the flat mop board, the wipes on the flat mop board are squeezed and cleaned. It also has the disadvantage that in the squeezing operation, it is necessary to hold the mop rod with one hand for positioning and the other hand to hold the squeezing mechanism, and push and pull the squeezing mechanism with one hand to realize the relative squeezing between the squeezing mechanism and the flat mop board. The movement is very laborious and the operability is not strong.

At present, when the flat mop is cleaned by using a mop bucket in the prior art, sometimes the mop bucket needs to be transported to the sewer during the cleaning process of the flat mop in the mop bucket through an external drain pipe, sometimes even not found To the sewage pipe, the drain on the side wall of the mop bucket needs to be aligned with the floor drain of the sewer. At the same time, even if the drain on the side wall of the mop bucket is aligned with the floor drain of the sewer, the sewage will still overflow around the drain of the sewer, causing the environment around the drain of the sewer. Poor, the experience brought to the operator is relatively poor. In addition, when squeezing and cleaning the flat mop through the mop bucket, it is usually necessary to pour a certain amount of water into the mop bucket first, and then squeeze and clean the wipes on the flat mop, and then the sewage generated during the cleaning process It cannot be discharged from the mop bucket in time, and thus the purpose of always washing with clean water cannot be realized, and the sewage after a certain period of use is manually poured out, so the cleaning efficiency is low.
