Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of cleaning tools, especially a cleaning structure suitable for cleaning flat mop or foamed cotton flat mop. BACKGROUND

[0002] There are many patents of mop buckets for cleaning flat mop, and a representative patent is a Chinese utility model patent with the patent number CN201821203889.3 (publication number CN209863678U) which discloses a flat mop tool, including a mop bucket and a flat mop; the mop bucket has a separate wringing area and a separate water holding area, and the bucket body of the wringing area is provided with a squeezing device; the flat mop includes a wiping object, a mop rod, and a flat mop plate connected to the lower end of the mop rod. When in use, the flat mop is rotated to a state where it can be squeezed, and then inserted into the squeezing device in the wringing area, and moved up and down to squeeze the wiping object through the squeezing device, and the water squeezed out of the wiping object is transferred to the water holding area through a water transfer device. Since the amount of water squeezed out of the wiping object is greater than the amount of water entering the squeezing area from the water holding area through the slow-release mechanism, the water in the wringing area can be basically completely transferred to the water holding area after multiple reciprocations, and the wiping object is also squeezed dry in this process. Then the water in the water holding area enters the wringing area through the slow-release mechanism, and the flat mop can enter the wringing area for squeezing and cleaning after the wiping object is dirty.

[0003] The applicant of the foregoing patent has also applied for many similar patents with different protection focuses, but the core is that the mop bucket has a separate wringing area and a separate water holding area, the water holding area is used to clean the mop, and the wringing area is used to squeeze dry the mop, and the water squeezed out of the wiping object is transferred to the water holding area through a water transfer device.

[0004] This flat mop cleaning tool has the following defects: cleaning and squeezing are divided into two areas, and two operations in different areas are required to complete a cleaning work, which is inconvenient for cleaning operation. In addition, the sewage washed off the wiping object each time is discharged back to the water holding area, which pollutes the water cup in the water holding area, and the contaminated water in the water holding area enters the wringing area through the slow-release mechanism, so that the water used for cleaning the mop next time is not clean water, which affects the cleaning of the wiping object; the slow-release mechanism may be a small hole that cannot be closed, so the lower end of the wiping object may be always soaked in the water in the wringing area during the operation of cleaning and squeezing the wiping object, which reduces the squeezing effect of the wiping object and cannot be fully squeezed dry.

[0005] In summary, the foregoing flat mop cleaning tool can be further improved. UTILITY MODEL CONTENTS

[0006] The technical problem to be solved by the utility model is to provide a cleaning structure of a mop with a bucket, which can ensure that clean water is used for each cleaning operation, can complete cleaning and wringing at the same time in one area, and can be smoothly operated.

[0007] The utility model discloses a technical scheme that solves the above technical problem: a cleaning structure for cleaning a flat mop, comprising a cleaning bucket and a mop, the mop comprising a mop head rotatably connected to the lower end of a mop rod; characterized in that: the mop head is provided with a wiping material, the cleaning bucket has a clean water area, a washing area and a sewage area which are independent of each other, the height of the sewage area is L1, the width of the sewage area is L2, L1 is greater than L2, the clean water area and the middle part of the washing area are connected through a water supply channel, and further comprising a switch for opening and closing the water supply channel, the switch is provided with a convex linkage part that can be inserted into the washing area and trigger the mop head to move downward; the washing area is provided with a water wringing plate that forms a squeezing action on the wiping material, the bottom of the washing area is provided with a support component that forms a support for the bottom end of the mop head entering the washing area, the water wringing plate has a water wringing and scraping edge that scrapes water from the wiping material, and the water wringing plate has a water blocking wall extending upward from one end away from the water wringing and scraping edge; during the process of the mop head entering the washing area downward, the inner wall of the washing area forms a support for the back plate of the mop head, the top surface of the water wringing plate is downwardly inclined from the water blocking wall to the water wringing and scraping edge to form a water guide surface, the outlet of the water supply channel is located below the water guide surface, the water blocking wall blocks a part of water squeezed and scraped from the wiping material and makes it flow back to the washing area along the water guide surface, and the part of water squeezed and scraped from the wiping material flows into the sewage area from above the water blocking wall; when the mop head is moved to a state supported by the support component, the liquid level in the washing area is lower than the top surface height of the wiping material and is located below the water guide surface.

[0008] To limit the downward movement of the mop head, the support component is a support column, a support table or a support frame arranged in the washing area.

[0009] As a preferred embodiment, the switch is in a strip shape, the upper end of the switch forms a convex rib or a concave groove for manual operation, which is convenient for manual operation, the switch moves downward to close the water supply channel, and the switch moves upward to open the water supply channel. The switch is automatically closed by the downward movement of the mop, and manual closing of the switch is not required, which is better linked with the mop and more reasonable in design.

[0010] Further improvement, the switch is constrained on the inner wall of the cleaning area by a rib-slot guiding structure, the guiding slot of the rib-slot guiding structure is arranged on one of the inner wall of the cleaning area and the side wall of the switch, and the guiding rib of the rib-slot guiding structure is arranged on the other one of the inner wall of the cleaning area and the side wall of the switch; during the downward movement of the switch, the rib-slot guiding structure applies a force on the switch in the direction of approaching the outlet end of the water supply channel. The rib-slot guiding structure makes the switch move along a preset track, and the force applied on the switch in the direction of approaching the outlet end of the water supply channel can make the switch better close the outlet end of the water supply channel, thereby avoiding water leakage.

[0011] To ensure that the switch does not move additionally after being moved downward to the position, the inner wall of the cleaning area is provided with a stop portion which blocks the downward movement of the switch to close the water supply channel.

[0012] To ensure that the squeezing plate swings within a proper angle range, the squeezing plate can swing, and further comprises a limiting structure which limits the swinging angle range of the squeezing plate, during the process that the mop head enters the cleaning cavity downwardly, the squeezing plate is blocked by the limiting structure and cannot turn downwardly, and during the process that the mop head leaves the cleaning cavity upwardly, the squeezing plate is blocked by the limiting structure and cannot turn upwardly. The downwardly swinging squeezing plate can make the scraping edge closer to the wiping object, and the scraping effect is better, and conversely, the upwardly turned squeezing plate can make the scraping edge farther away from the wiping object, thereby facilitating the separation of the mop head.

[0013] Alternatively, the cleaning bucket comprises an outer bucket, a first inner bucket and a second inner bucket, the inner cavity of the outer bucket constitutes the sewage area, the inner cavity of the first inner bucket constitutes the clean water area, the inner cavity of the second inner bucket constitutes the cleaning area, and the first inner bucket and the second inner bucket are at least partially installed in the outer bucket. The outer bucket and the two inner buckets are better isolated from each other, and the sewage in the outer bucket cannot enter the two inner buckets. Of course, a partition plate can be arranged in the outer bucket to separate it into the clean water area, the cleaning area and the sewage area.

[0014] To ensure that a relatively small amount of water can also meet the requirement that the highest water level in the cleaning area moves upwardly as much as possible after the mop enters the cleaning area, at least a part of an inner wall of the second inner bucket is arranged in a slanting manner, so that the cleaning area is in a flared shape from bottom to top. In this way, the wiping object can be soaked with relatively less water as much as possible.

[0015] To facilitate water injection into the second inner bucket, the bottom surface of the first inner bucket is higher than the bottom surface of the second inner bucket.

[0016] Compared with the prior art, the advantages of this utility model are as follows: the cleaning bucket has independent clean water zone, washing zone, and wastewater zone; the clean water zone is filled with clean water. During washing, when the switch is turned on, the clean water zone supplies water to the washing zone through the water supply channel. The mop head rotates to a squeezing state that is basically parallel to the mop handle. In this state, the mop head and mop handle are inserted into the washing zone. The mop head triggers the linkage on the switch, the switch closes the water supply channel, and the mop head moves up and down in the washing zone. The wringer scrapes and cleans the wiped items. The inner wall of the washing zone supports the back plate of the mop head. The wringer can better apply force to the wiped items for cleaning and squeezing. The water-blocking wall blocks a small amount of water squeezed off the wiped items and directs it towards the washing zone along the water guide surface. The water level in the cleaning zone is lower than the top of the cleaning material and below the water guide surface. This means that initially, the water in the cleaning zone does not need to completely wet the cleaning material, saving water. Most of the water squeezed off the cleaning material flows over the water barrier into the wastewater zone. By repeatedly moving the mop up and down until the water in the cleaning zone is basically removed, the water on the cleaning material can be thoroughly squeezed out. Cleaning and squeezing are completed in just one cleaning zone, making the squeezing operation more convenient. For the second cleaning, simply turn on the switch again, and the clean water zone will supply water to the cleaning zone again through the water supply channel. Repeat the above operation to complete the second cleaning, ensuring that the mop is clean water every time it is cleaned. Attached Figure Description
