Description

Technical Field

[0001] The embodiment of the present invention relates to a cleaning device of a squeeze flat mop. Background Art

[0002] In the prior art, there are three ways to dehydrate a flat mop: foot-operated squeezing dehydration, in which a foot-operated squeezing device is arranged on the mop bucket, and the foot-operated squeezing device includes a squeezing basket arranged in the mop bucket, a pedal hinged on the upper part of the mop bucket and opposite to the squeezing basket, and the pedal and the squeezing basket form a squeezing space. When dehydrating, the mop on the mop board of the flat mop needs to be removed first, and the mop needs to be placed in the squeezing space, and then the pedal is stepped on to shrink the squeezing space to achieve the purpose of squeezing out the water on the mop. This form of dehydration method requires the design of a complex foot-operated squeezing device, which is costly; when squeezing water, the mop needs to be removed first, and the foot needs to be lifted for stepping operation, which is troublesome to operate.

[0003] The second method is centrifugal spin dehydration, which uses a hand-pressed spin mop rod. When dehydrating, the mop plate of the flat mop needs to be bent at both ends and placed in the dehydration area of ​​the mop bucket, and the mop rod is pressed down to make the mop plate of the flat mop spin centrifugally dehydrated. This form of dehydration method requires the mop plate of the flat mop to be designed as a bendable structure, which is relatively complex in structure and needs to be coordinated with the hand-pressed spin mop rod, which is costly.

[0004] 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 plate movably connected to the mop rod, and a water squeezing mechanism on the mop rod, and the water squeezing mechanism and the flat mop plate are relatively squeezed and moved to achieve squeezing and cleaning of the wiped objects on the flat mop plate. It also has the disadvantage that: when squeezing water, one hand needs to hold the mop rod for positioning and the other hand needs to hold the water squeezing mechanism, and the relative squeezing movement between the water squeezing mechanism and the flat mop plate is achieved by pushing and pulling the water squeezing mechanism with one hand, which is very laborious and not easy to operate.

[0005] At present, in the prior art, when a flat mop is cleaned by using a mop bucket, it is sometimes necessary to transport the sewage generated by the flat mop in the mop bucket during the cleaning process to the sewer through an external sewage pipe. Sometimes, the sewage pipe cannot be found, and the drainage port set on the side wall of the mop bucket needs to be aligned with the sewer sewage port. At the same time, even if the drainage port on the side wall of the mop bucket is aligned with the sewer sewage port, the sewage will still overflow to the surrounding of the sewer sewage port, resulting in a poor environment around the sewer sewage port, which brings a poor experience to the operator. In addition, when squeezing and cleaning the flat mop with a mop bucket, it is generally necessary to first pour a certain amount of clean water into the mop bucket, and then squeeze and clean the wipes on the flat mop. Then, the sewage generated during the cleaning process cannot be discharged from the mop bucket in time, and thus the purpose of continuous flushing with clean water cannot be achieved. Moreover, the sewage after a certain period of use is manually poured out, so the cleaning efficiency is low. Summary of the invention

[0006] In view of the above problems existing in the prior art, the main purpose of the present invention is to provide a cleaning device for squeezing a flat mop, which uses a mop bucket to clean and squeeze water from the flat mop.

[0094] When in use, the mop head 202 is rotated to a state where water can be squeezed and cleaned, that is, the mop head 202 is rotated to a state where it is parallel or substantially parallel to the mop rod 201. When squeezing water and cleaning, the mop head 202 moves back and forth in the stroking opening 101 on the stroking mechanism to squeeze water and clean the wiped material on the mop head 202 through the stroking plate 102.

[0095] The specific process of squeezing water and cleaning the flat mop by the stroking head mechanism provided on the mop bucket is as follows: when squeezing water and cleaning, the mop head 202 is first rotated to a state where water can be squeezed and cleaned, and then the mop head 202 is inserted into the stroking opening 101 of the stroking head mechanism. When the mop head 202 is squeezed and moved toward the inside of the stroking opening 101 of the cleaning bucket 300 (i.e., squeezed and moved downward), the stroking plate 102 contacts the wiping material 203 on the mop head 202 and the stroking plate 102 moves and squeezes the wiping material 203. At the same time, the two rollers are abutted against and slidably connected to the back side of the mop head 202, and the wiping material on the mop head is closely matched with the stroking plate 102 through the sliding squeezing of the roller 115. During the downward movement of the mop head 202, the width of the stroking opening 101 is the smallest, and then the stroking plate 102 is used to fully clean the wiping material 203. When the mop head 202 is squeezed and moved upward from the mop bucket, the back of the mop head 202 abuts against the roller 115, so that the end of the roller mounting portion 117 close to the roller 115 can rotate upward through the cooperation of the rotating pin 121 and the mounting hole 122, thereby increasing the distance between the roller and the stroking plate. Even if the opening of the stroking mouth or the width of the stroking mouth increases, the friction between the stroking plate and the wiping object on the mop head is reduced, reducing the effect of squeezing water or cleaning, that is, it is easier to lift the mop head upward, which is convenient to operate, labor-saving, and prevents water from splashing to the operator, and reduces the wear of the mop head, thereby extending the service life of the mop head.

When the flat mop is inserted into the stroking opening 101 and moves downward, the back of the mop head 202 presses against the roller 115 and makes the roller 115 slide to the bottom of the rectangular limiting hole 131, and at the same time, the upper end of the roller 115 is flush with the upper end of the stroking plate 102. At this time, the distance between the roller 115 and the stroking plate 102 is the smallest and the roller 115 is tightly against the back of the mop head 202, that is, the roller 115 and the mop head 202 are tightly matched. When the flat mop continues to move downward, the wipes on the mop head 202 in the flat mop 200 are squeezed and squeezed out by the stroking plate 102; when the flat mop 200 passes through the mop When the rod 201 moves the mop head 202 upward along the stroking mouth 101, the roller 115 moves with the mop head 202 to the top of the limiting hole 131. At this time, the distance between the roller 115 and the stroking plate 102 is the largest, and then the friction resistance between the roller 115 and the mop head 202 becomes the smallest, which facilitates the upward movement of the mop head 202, thereby realizing the one-way stroking of the flat mop by the stroking plate 102, and the mop head 202 moves up and down in the stroking mouth 101 to realize the squeezing and squeezing operation of the wiped object; in addition, since the mop head 202 and the roller are slidably connected, it is more labor-saving and convenient to operate when squeezing and squeezing water from the flat mop through the stroking head mechanism.
