Description

A cleaning device for squeezing a flat mop

technical field

The embodiment of the utility model relates to a cleaning device for squeezing a flat mop.

Background technique

In the prior art, there are three ways to dehydrate the flat mop by foot pressing type dehydration, which is provided with a foot pressing and pressing device on the mop bucket. The pedal on the upper part of the mop bucket and opposite to the squeezing basket, the pedal and the squeezing basket form a squeezing space. When dehydrating, you need to remove the mop on the mop board of the flat mop first, and place the mop in the squeezing space. , and then step on the pedal to shrink the water squeezing space to squeeze out the water on the mop. This type of dehydration method requires the design of a foot pressing device with a complex structure, which is costly; when squeezing water, the mop needs to be removed first, and the foot needs to be lifted to perform the stepping operation, which is troublesome.

The second method is centrifugal rotary dehydration, which uses a hand-pressed rotary mop bar. During dehydration, both ends of the mop plate of the flat mop need to be bent and placed in the dehydration area of the mop bucket, and the mop bar is pressed down to make the mop. The mop plate of the flat mop was spin-dehydrated by centrifugation. This type of dehydration method requires the mop plate of the flat mop to be designed into a bendable structure, which is complicated in structure, and needs to be matched with a hand-pressed rotary mop rod, resulting in high cost.

The third method is hand-push extrusion dehydration, such as Chinese utility model patents ZL200720192814.5, ZL201320019718.6, ZL201420624020.1, etc., which include a mop bar, a flat mop board movably connected to the mop bar, and a mop bar on the mop bar. A water squeezing mechanism is provided, and the water squeezing and cleaning of the wipes on the flat mop board are realized through the relative squeezing movement between the water squeezing mechanism and the flat mop board. It also has the disadvantage that: during the squeezing operation, it is necessary to hold the mop rod with one hand for positioning and the squeezing mechanism with the other hand, and push and pull the squeezing mechanism with one hand to realize the relative squeezing between the squeezing mechanism and the flat mop board. Moving movement, the operation is very laborious, and the operability is not strong.

At present, when the mop bucket is used to clean the flat mop in the prior art, it is sometimes necessary to use the mop bucket to transport the sewage generated during the cleaning process of the flat mop in the mop bucket to the sewer through the external sewage pipe, and sometimes it is not even possible to find it. To the sewage pipe, it is necessary to align the drain port on the side wall of the mop bucket with the sewer drain port. At the same time, even if the drain port on the side wall of the mop bucket is aligned with the sewer drain port, the sewage will still overflow to the surrounding of the sewer drain port, resulting in sewer drain. The environment around the mouth is poor, and 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 clean water into the mop bucket first, and then squeeze and clean the wipes on the flat mop, and then clean the sewage generated during the process. It cannot be discharged from the mop bucket in time, so that the purpose of rinsing with clean water cannot be achieved all the time, and the sewage after a certain period of time is poured out manually, so the cleaning efficiency is low.
