Description

TECHNICAL FIELD

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

[0002] There are many patents of mop bucket for cleaning flat mop, and a representative patent is a Chinese utility model patent with patent No. CN201821203889.3 (publication No. CN209863678U) which discloses a flat mop tool, including a mop bucket and a flat mop; the mop bucket has a separate squeezing water area and a separate water holding area, and a squeezing device is arranged on the bucket body of the squeezing water area; the flat mop includes a wiping object, a mop rod, and a flat mop plate connected to the lower end of the mop rod. During use, the flat mop is rotated to a state where it can be squeezed, and then the squeezing device is inserted into the squeezing water area, and the wiping object is squeezed by moving up and down to pass 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 squeezing water 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 squeezing water area through the slow-release mechanism, and the flat mop can enter the squeezing water 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 squeezing water area and a separate water holding area, the water holding area is used to clean the mop, and the squeezing water area is used to squeeze the mop dry, 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 polluted water in the water holding area enters the squeezing water 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 squeezing water 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 utility model provides a technical problem to be solved is to provide a kind of cleaning device for cleaning flat mop, which ensures that each cleaning operation is clean water, can complete cleaning and wringing in one area simultaneously, and the cleaning operation is smooth.

[0007] The utility model discloses a technical scheme for solving the above technical problems: a cleaning device for cleaning flat mop, including cleaning bucket and mop, the mop includes the mop head of rotation connection in the lower end of mop stick, be equipped with wiping material on the mop head;Its characterized in that: the cleaning bucket has the clean water area, washing area and sewage area that are independent of each other;Washing area is equipped with the water squeezing component that forms the extrusion to wiping material, the bottom of washing area is equipped with the support component that forms the support to the bottom end of mop head entering it, the middle part of clean water area and washing area are communicated by water supply channel, water supply channel and water squeezing component are spaced apart and set up oppositely, the height of washing area is L1, the length of washing area is L2, L1 is greater than L2, and it further includes switch for opening and closing water supply channel, the switch is equipped with the convex mop trigger that can be inserted into washing area and linkage portion that moves downward;The back plate of mop head is equipped or buckled on the lower end of wiping material, and the bottom surface of wiping material is bonded on the back plate of mop head, the mop head rotates to the extrusion state of substantially parallel with mop stick, the mop head and mop stick are inserted into the washing area and move up and down in this state, and the wiping material is extruded and scraped by the water squeezing component;Washing area is further equipped with drainage channel for draining the water extruded and scraped on wiping material to sewage area, and reflux channel for returning to washing area.

[0008] To limit the degree of mop head moving down, the above-mentioned support component is a support column, a support table or a support frame arranged in the washing area.

[0009] As a preferred embodiment, the water squeezing component is plate-shaped and can swing, the front part of the water squeezing component forms a scraper part with a thickness decreasing from back to front, an upward extending baffle is arranged at least at the back of the top surface of the water squeezing component, the upper part of the baffle forms the drainage channel, and the front face of the baffle and the top surface of the water squeezing component enclose the reflux channel. The scraper part with a thickness decreasing from back to front is more conducive to clearing the dirt on the wiping material, the baffle can block the water flow to make it return to the washing area, the height of the baffle is limited, and part of the water extruded and scraped on the wiping material can pass over the baffle, forming the drainage channel.

[0010] To ensure the squeezing part swings within a proper angle range, a limiting structure is further arranged to limit the swinging angle range of the squeezing part. During the process of the mop head entering the cleaning area, the squeezing part is blocked by the limiting structure and cannot be flipped downward. During the process of the mop head leaving the cleaning area, the squeezing part is blocked by the limiting structure and cannot be flipped upward. The downward swinging squeezing part can make the scraper part closer to the wiping material, and the water scraping effect is better. On the contrary, the upward flipping squeezing part can make the scraper part farther away from the wiping material, and the mop head is easier to be separated.

[0011] Alternatively, the cleaning bucket includes 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, and the inner cavity of the second inner bucket constitutes the cleaning area. 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 can be arranged in the outer bucket to separate it into the clean water area, the cleaning area and the sewage area.

[0012] To ensure that a smaller amount of water can also meet the requirement that the highest water level in the mop after entering the cleaning area moves upward as much as possible, at least a part of an inner wall of the second inner bucket is arranged to be inclined, so that the cleaning area is flared from bottom to top. In this way, the wiping material can be soaked with relatively less water as much as possible.

[0013] As a preferred embodiment, the upper end of the switch forms a convex rib or a concave groove 61 for operation by a person. 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 no additional manual operation is required. The switch is better linked with the mop, and the design is more reasonable.

[0014] Further improvement, the switch is constrained on the inner wall of the cleaning area by a rib and groove guide structure. A guide groove in the rib and groove guide structure is arranged on one of the inner wall of the cleaning area and the side wall of the switch, and a guide rib in the rib and groove guide 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 and groove guide structure applies a force to the switch in the direction of approaching the water outlet end of the water supply channel. The rib and groove guide structure makes the switch move along a predetermined track, and the force applied to the switch in the direction of approaching the water outlet end of the water supply channel can make the switch better close the outlet end of the water supply channel, avoiding water leakage.

[0015] To ensure that the switch does not move additionally after being moved downward to the position, a stop portion is arranged on the inner wall of the cleaning area to block the downward movement of the switch to close the water supply channel.

[0016] Compared with the prior art, the mop has the advantages that the cleaning barrel has a water purification area, a cleaning area and a sewage area which are independent of each other, clean water is filled in the water purification area, when cleaning, the switch is opened, the water purification area supplies water to the cleaning area through the water supply channel, the mop head is rotated to a squeezable state in which the mop head and the mop rod are substantially parallel, the mop head and the mop rod are inserted into the cleaning area in the state, the mop head triggers the linkage part on the switch, the switch closes the water supply channel, the mop head is moved up and down in the cleaning area, the wiping object is squeezed and cleaned by the water squeezing part, most of the sewage squeezed and cleaned from the wiping object each time is drained to the sewage area through the drainage channel, and a small amount of sewage is returned to the cleaning area through the return channel, the wiping object in the cleaning area is soaked, so that the water in the cleaning area does not need to be completely soaked in the wiping object in the initial state, and water can be saved; the lower end of the wiping object is sleeved or buckled on the back plate of the mop head, and the bottom surface of the wiping object is bonded to the back plate of the mop head, so that the lower end of the wiping object is not warped under the squeezing and scraping edge of the water squeezing part during the movement of the mop head downward, and the cleaning operation is ensured to be smooth and not jammed. The mop is repeatedly moved up and down until the water in the cleaning area is basically drained by the drainage channel, the water on the wiping object is fully squeezed out, the cleaning and squeezing are completed in one cleaning area, and the water squeezing operation is more convenient; during the second cleaning, the switch is opened again, the water purification area supplies water to the cleaning area through the water supply channel again, and the foregoing operation is repeated to complete the second cleaning, and the clean water is ensured to clean the mop each time. The water supply channel and the water squeezing part are arranged in a spaced relationship, compared with being arranged on the same side, packaging can be saved, the height of the cleaning area is L1, the length of the cleaning area is L2, L1 is greater than L2, and therefore, the water with a smaller volume can form a high water level in the cleaning area, and water can be saved.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] like Figures 1 to 16 The figure shown is a preferred embodiment of the present invention.

[0035] A cleaning device for cleaning a flat mop includes a cleaning bucket 1 and a mop. The mop includes a mop head 3 rotatably connected to the lower end of a mop handle 2, and the mop head 3 is provided with a wiping material 4. The wiping material 4 can be a fiber cloth or foam.

[0036] The cleaning bucket 1 has three independent areas: a clean water area 1a, a washing area 1b, and a wastewater area 1c. The bottom of the washing area 1b is provided with a support component 7 that supports the bottom end of the mop head 3 that enters it. The support component 7 is a support column, support platform, or support frame located within the washing area 1b. The cleaning bucket 1 includes an outer bucket 11, a first inner bucket 12, and a second inner bucket 13. The inner cavity of the outer bucket 11 constitutes the wastewater area 1c, the inner cavity of the first inner bucket 12 constitutes the clean water area 1a, and the inner cavity of the second inner bucket 13 constitutes the washing area 1b. The first inner bucket 12 and the second inner bucket 13 are at least partially installed inside the outer bucket 11. One inner wall of the second inner bucket 13 is at least partially inclined, causing the washing area 1b to flare out from bottom to top.

[0037] The middle parts of the water purification zone 1a and the cleaning zone 1b are connected by a water supply channel D. The water supply channel D is arranged opposite to the water squeezing component 5 at intervals. The height of the cleaning zone 1b is L1, and the length of the cleaning zone 1b is L2, where L1 is greater than L2.

[0038] It also includes a switch 6 for opening and closing the water supply channel D. The switch 6 has a protruding linkage part 62 that can be triggered by a mop inserted into the cleaning area 1b to move downward. The lower end of the wiping material 4 is sleeved or fastened to the back plate 31 of the mop head 3, and the bottom surface of the wiping material 4 is adhered to the back plate 31 of the mop head 3. The cleaning area 1b is provided with a squeezing component 5 that squeezes the wiping material 4. The mop head 3 is rotated to a squeezing state that is basically parallel to the mop handle 2. In this state, the mop head 3 and the mop handle 2 are inserted into the cleaning area 1b and move up and down. The squeezing component 5 squeezes and scrapes the wiping material 4. The cleaning area 1b is also provided with a drainage channel S1 for draining the water squeezed off the wiping material 4 to the sewage area and a return channel S2 for returning to the cleaning area 1b.

[0039] The wringing component 5 is plate-shaped and can swing. The front of the wringing component 5 forms a scraper section 53 whose thickness decreases from back to front. At least behind the top surface of the wringing component 5, an upwardly extending baffle 51 is provided. The drainage channel S1 is formed above the baffle 51, and the front of the baffle 51 and the top surface of the wringing component 5 form the return channel S2. It also includes a limiting structure 8 that limits the swing angle range of the wringing component 5. When the mop head 3 enters the cleaning area 1b downwards, the wringing component 5 is prevented from rotating downwards by the limiting structure 8; when the mop head 3 leaves the cleaning area 1b upwards, the wringing component 5 is prevented from rotating upwards by the limiting structure 8.

[0040] The switch 6 is elongated, with a raised rib or groove 62 at its upper end extending above the cleaning area 1b for operation. Moving the switch 6 downwards closes the water supply channel D, while moving it upwards opens the water supply channel D. The switch 6 is constrained to the inner wall of the cleaning area 1b by a ribbed guide structure 9. The guide groove 9a of the ribbed guide structure 9 is located on one of the inner wall of the cleaning area 1b and the side wall of the switch, and the guide rib 9b of the ribbed guide structure 9 is located on the other of the inner wall of the cleaning area 1b and the side wall of the switch. During the downward movement of the switch 6, the ribbed guide structure 9 applies a force to the switch 6 towards the outlet end of the water supply channel D. The inner wall of the cleaning area 1b is provided with a stop 1b1 that blocks the downward movement of the switch to close the water supply channel D.

[0041] The cleaning bucket 1 has three independent zones: a clean water zone 1a, a washing zone 1b, and a wastewater zone 1c. The clean water zone is filled with clean water. During washing, switch 5 is turned on, and water is supplied from the clean water zone 1a to the washing zone 1b via the water supply channel D. The mop head 3 rotates to a squeezeable state that is essentially parallel to the mop handle 2. In this state, the mop head 3 and the mop handle 2 are inserted into the washing zone 1b. The mop head 3 triggers the linkage 61 on switch 6, which closes the water supply channel D. The mop head 3 moves up and down within the washing zone 1b, using the squeezing component 5 to scrape and clean the wiping object 4. Most of the wastewater scraped off the wiping object 4 each time is drained through the drainage channel S1. The wastewater is discharged to the sewage area 1c, and a small portion of the wastewater flows back to the cleaning area 1b through the return channel S2 to wet the wiping material 4 therein. This means that in the initial state, the water in the cleaning area 1b does not need to fully wet the wiping material 4, thus saving water. The lower end of the wiping material 4 is fitted or fastened to the back plate 31 of the mop head 3, and the bottom surface of the wiping material 4 is adhered to the back plate 31 of the mop head 3. In this way, during the downward movement of the mop head 3, the lower end of the wiping material 4, because it is fitted or fastened to the back plate 31 of the mop head 3, will not warp under the squeezing and scraping edge 51 of the wringing component 5, ensuring that the cleaning operation is smooth and does not get stuck. Move the mop up and down repeatedly until the water in the cleaning area is basically removed by the drainage channel. This will allow you to fully wring out the water from the wiped item 4. The cleaning and wringing can be completed in just one cleaning area 1b, making the wringing operation more convenient. For the second cleaning, simply turn on the switch again, and the clean water area will supply water to the cleaning area 1b 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.
