Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning tools, and in particular to a flat mop cleaning tool based on a mop cleaning bucket, which is suitable for cleaning flat mops or foam flat mops. Background Technology

[0002] There are numerous patents related to mop buckets used for cleaning flat mops. A representative patent is Chinese utility model patent 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 wringing area is equipped with a squeezing device. The flat mop includes a cleaning material, a mop handle, and a flat mop plate connected to the lower end of the mop handle. In use, the flat mop is rotated to a squeezing state, and then the squeezing device is inserted into the wringing area. Moving it up and down squeezes the cleaning material, and the squeezed water is transferred to the water-holding area via a water transfer device. Because the amount of water squeezed out is greater than the amount of water entering the wringing area from the water-holding area through the slow-release mechanism, after multiple repetitions, almost all the water in the wringing area can be transferred to the water-holding area, and the cleaning material is also squeezed dry during this process. Afterwards, the water in the water-holding area enters the wringing area through the slow-release mechanism. When the flat mop gets dirty, it can then enter the wringing area for wringing and cleaning.

[0003] The applicant of the aforementioned patent has also applied for many similar patents with different focuses of protection, but the core of them is that the mop bucket has an independent squeezing area and an independent water holding area, and the water squeezed out of the wiping material is transferred to the water holding area through a water transfer device.

[0004] This indicates that flat mop cleaning tools have the following drawbacks: 1. Each time the wastewater is washed off the mop, it is discharged back into the water collection area, causing the water cup in the water collection area to become contaminated. The contaminated water in the water collection area then enters the squeezing area through the slow release mechanism, so the water used to wash the mop next time is not clean water, which affects the cleanliness of the mop.

[0005] 2. The amount of water released into the wringing zone through the slow-release mechanism each time cannot be quantitatively controlled. That is, the amount of water used to wash the mop each time is not fixed, and the water used to wash the mop may not fully submerge the objects being wiped, further affecting the cleanliness of the objects.

[0006] 3. The slow-release mechanism may be a small hole that cannot be closed. In this case, during the cleaning and squeezing process, the lower end of the wipe may always be soaked in water in the squeezing area, which will reduce the squeezing effect and prevent the wipe from being fully squeezed out.

[0007] In conclusion, the aforementioned cleaning tools for cleaning flat mops or sponge mops can be further improved. Summary of the Invention

[0008] The technical problem to be solved by this utility model is to provide a flat mop cleaning tool with a reasonable structure, which can achieve quantitative water supply, ensure that the water used to clean the mop is clean every time it is washed, and separate the clean and dirty operations of washing and wringing.

[0009] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a flat mop cleaning tool for separating clean and dirty parts, comprising a cleaning bucket and a mop, wherein the mop includes a mop head rotatably connected to the lower end of the mop handle, and the mop head is provided with a wiping agent; characterized in that: the cleaning bucket includes an outer bucket, a clean water inner bucket, and a washing inner bucket, wherein the washing inner bucket and the clean water inner bucket are at least partially installed inside the outer bucket, the clean water inner bucket constitutes a clean water area, the washing inner bucket constitutes a washing area, the washing inner bucket and the clean water inner bucket are connected through a water supply channel, the water supply channel is controlled to open and close by a switch, the top opening of the clean water inner bucket is provided with a bucket lid to form a closure, the bucket lid is provided with a water inlet, the water inlet... The device is equipped with a sealed cap, and the opening of the inner cleaning tub has an outward-curving reinforced flange. The outer tub has two water-squeezing devices, a first and a second, for the mop head to pass through. The first water-squeezing device corresponds to the inner cleaning tub, and the mop head can enter the inner cleaning tub after passing through the first water-squeezing device. The second water-squeezing device is located outside the inner cleaning tub and the clean water tub, and the mop head can pass through the second water-squeezing device and move up and down to perform a water-squeezing operation. The first water-squeezing device has a first drainage channel for transferring the water from wiping the object to the outside of the inner cleaning tub, and the outlet of the water supply channel is lower than the first drainage channel.

[0010] Because there is an atmospheric pressure difference between the inside and outside of the inner water tank, to strengthen the side wall and prevent deformation that could affect the sealing effect, the inner water tank is provided with reinforcing ribs with alternating concave and convex sections on its surrounding wall as an improvement.

[0011] To prevent the inner tub from wobbling relative to the outer tub during washing, the outer wall of the inner tub is provided with a protruding abutment that abuts against the corresponding inner wall of the outer tub. The abutment against the inner wall of the outer tub enhances the structural stability of both components.

[0012] Preferably, the first and second dewatering devices are located on the same side of the inner water tank. This layout makes the washing and dewatering positions adjacent, which is more user-friendly and also facilitates the rational layout of the drainage circuit, resulting in a more compact structure.

[0013] Preferably, the aforementioned first squeezing device includes a first squeezing frame with a first squeezing hole, and a first squeezing component is provided inside the first squeezing hole. The first squeezing component can be a squeezing scraper, a squeezing protrusion, a cleaning roller, or a water-absorbing mechanism. Alternatively, the squeezing component may not be provided inside the first squeezing hole; water in the cleaning area can be absorbed by the wiping material or another adsorption component on the mop head. The mop head can pass through the first squeezing hole, and the first squeezing component squeezes the wiping material on the up-and-down moving mop head, thereby moving, squeezing, and squeezing the water from the wiping material. As the mop head moves downward into the first squeezing hole, the inner wall of the first squeezing hole supports the back plate of the mop head. The first squeezing component can clean the wiping material, and the support of the inner wall of the first squeezing hole on the back plate of the mop head allows the first squeezing component to squeeze and scrape the wiping material more forcefully, resulting in a better cleaning effect. Of course, cleaning bristles can also be provided inside the first squeezing hole.

[0014] Preferably, the aforementioned second squeezing device includes a second squeezing frame with a second squeezing hole. A second squeezing component is disposed within the second squeezing hole. The second squeezing component can be a scraper, a squeezing protrusion, or a cleaning roller. The mop head can pass through the second squeezing hole. The second squeezing component squeezes the wiping material on the up-and-down moving mop head, thereby moving, squeezing, and squeezing the water from the wiping material. As the mop head moves downwards into the second squeezing hole, the inner wall of the second squeezing hole supports the back plate of the mop head. The second squeezing component can squeeze the wiping material, and the inner wall of the second squeezing hole supports the back plate of the mop head, allowing the second squeezing component to squeeze the wiping material more forcefully, resulting in a better squeezing effect.

[0015] Further improvements include the formation of an independent squeezing zone within the outer tub. The second wringer corresponds to this squeezing zone, allowing the mop head to pass through it and enter the squeezing zone. This squeezing zone ensures the squeezing operation is completed in a separate area, facilitating a near-waterless environment where the wiped items can be squeezed out more thoroughly.

[0016] One way to implement the squeezing area is to divide the outer barrel into two independent areas by a partition, one being a wastewater area and the other a squeezing area, with the clean water tank and the washing tank located in the wastewater area. Alternatively, the outer barrel may be housed within a squeezing inner barrel, with the interior space of the outer barrel forming the wastewater area and the squeezing inner barrel forming the squeezing area.

[0017] Further improvements include a second drain channel on the second spout wringing device that transfers water squeezed from the wiping surface to the outer bucket. This second drain channel ensures that virtually no water remains in the wringing area, resulting in better wringing performance of the mop head. Preferably, a lifting protrusion can be provided at the bottom of the wringing area, so that even if a small amount of water flows into the wringing area, it will be located below the lifting protrusion and will not wet the wiping surface at the bottom of the mop head.

[0018] To better achieve automatic water control, further improvements are made. Simultaneously, air enters the space above the liquid surface in the clean water zone through the water supply channel while water is being injected into the cleaning zone, until the water in the cleaning zone submerges the outlet or inlet of the water supply channel. This better utilizes atmospheric pressure. When the water in the cleaning zone submerges the outlet of the water supply channel, water supply to the cleaning zone ceases. When the water in the cleaning zone does not submerge the outlet of the water supply channel, and the switch is open, water from the clean water zone automatically supplies water to the cleaning zone. Air enters the space above the effective liquid surface in the clean water zone through the water supply channel, ensuring smooth water supply without the need for an additional air inlet valve, resulting in a simpler structure.

[0019] Alternatively, a one-way air inlet valve may be provided on the wall or bottom of the water purification zone or on an associated third component, which allows air to enter the space above the liquid surface of the water purification zone from the outside.

[0020] Preferably, the switch moves downward to close the water supply channel, and moves upward to open the water supply channel; the mop cooperates with the switch, so that the downward movement of the mop causes the switch to move downward. To facilitate coordinated operation with the mop, the switch is provided with a protrusion that cooperates with the downward-moving mop.

[0021] To ensure a stable connection between the two inner tubs and facilitate assembly, the aforementioned cleaning inner tub and clean water inner tub are fitted together to form a single unit, which can be detached from the outer tub. This unit can be moved to the faucet for independent water filling and also facilitates cleaning of the outer tub.

[0022] Compared with the prior art, the advantages of this utility model are as follows: It features independent clean water inner tub and cleaning inner tub. The clean water inner tub provides clean water to the cleaning inner tub, forming the clean water zone, while the cleaning inner tub forms the cleaning zone. The opening of the cleaning inner tub has an outward-curving reinforcing flange, increasing its strength and preventing deformation. Before cleaning, the cap is opened, and water is injected into the clean water inner tub through the water inlet. After filling, the cap is closed. During cleaning, the switch is turned on, and the clean water zone supplies water to the cleaning zone through the water supply channel. Because the top of the clean water zone is closed, the water in the cleaning zone does not exceed the outlet or inlet of the water supply channel. Under atmospheric pressure, the cleaning zone no longer supplies water to the cleaning zone, completing the quantitative water supply operation. After the quantitative water supply is completed, the mop... The mop head enters the cleaning zone through the first wringer and moves up and down. The clean water in the cleaning zone cleans the object being wiped. During the cleaning process, the water in the cleaning zone is gradually drained out through the first drainage channel, completing the cleaning operation. After cleaning, the mop head is detached from the first wringer and inserted into the second wringer, moving up and down repeatedly. The second wringer applies reciprocating pressure to the object being wiped, thoroughly squeezing out the water. This cleaning tool ensures that the water used to wash the mop is clean and supplied in a measured amount each time, resulting in better cleaning and water conservation. The wringing operation is performed in an area separate from and outside the cleaning zone, without interference, resulting in better wringing performance compared to wringing in the cleaning zone.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1-13 The figure shown is a preferred embodiment of the present invention.

[0026] A flat mop cleaning tool with clean and dirty separation includes a cleaning bucket 1 and a mop. The mop includes a mop head 3 rotatably connected to the lower end of the mop handle 2. The mop head 3 is provided with a wiping material 4. The wiping material 4 can be a fiber cloth or foam.

[0027] The cleaning tub 1 includes an outer tub 11, a clean water inner tub 12, and a washing inner tub 13. The washing inner tub 13 and the clean water inner tub 12 are at least partially installed inside the outer tub 11. The clean water inner tub 12 forms a clean water zone 1a, and its surrounding wall is provided with reinforcing ribs 121 spaced apart. The washing inner tub 13 forms a washing zone 1b, and its outer wall has a raised abutment portion 132 that abuts against the corresponding inner wall of the outer tub 11. The top opening of the clean water inner tub 12 is provided with a tub lid 10 to form a closure. The tub lid 10 has a water inlet 101, which is sealed with a cap 102. A sealing ring 103 seals between the top opening of the clean water inner tub 12 and the tub lid 10. The opening of the washing inner tub 13 has an outwardly flared reinforcing flange 131.

[0028] The inner cleaning tub 13 and the inner clean water tub 12 are connected by a water supply channel E. While water is being supplied to the cleaning zone 1b via the water supply channel E, air also enters the space above the liquid surface in the clean water zone 1a through the water supply channel E until the water in the cleaning zone 1b submerges the outlet E2 or inlet E1 of the water supply channel E. The water supply channel E is controlled by a switch 7; moving the switch 7 downwards closes the water supply channel E, while moving it upwards opens it. The mop works in conjunction with the switch 7, causing the switch 7 to move downwards as the mop moves downwards. The switch 7 has an easy-to-operate operating end 71 and a protrusion 72 that engages with the downward-moving mop.

[0029] The outer tub 11 is equipped with two wringing devices, a first wringing device 5 and a second wringing device 6, for the mop head 3 to pass through. The first wringing device 5 and the second wringing device 6 are located on the same side of the inner tub 12. The first wringing device 5 corresponds to the inner tub 13, and the mop head 3 can enter the inner tub 13 after passing through the first wringing device 5.

[0030] The first swiping and squeezing device 5 includes a first swiping frame 9a with a first swiping hole 5a. A first squeezing component 5b is provided inside the first swiping hole 5a. The mop head can pass through the first swiping hole 5a. The first squeezing component 5b squeezes the wiping material 4 on the mop head 3 as it moves up and down, thereby moving, squeezing and squeezing the water out of the wiping material 4. As the mop head 3 moves downward into the first swiping hole 5a, the inner wall of the first swiping hole 5a provides support for the back plate of the mop head 3.

[0031] The outer tub 11 forms an independent squeezing area 1c. The second spout squeezing device corresponds to the squeezing area 1c. The mop head 3 can enter the squeezing area 1c after passing through the second spout squeezing device 6. The outer tub 11 is divided into two independent areas by a partition 14, one of which is a sewage area 1d and the other is the squeezing area 1c. The clean water tub 12 and the washing tub 13 are located in the sewage area 1d. The washing inner tub 13 and the clean water inner tub 12 are fitted together to form a unit, which can be set separately from the outer tub 11. The second swiping and squeezing device 6 includes a second swiping frame with a second swiping hole 6a. A second squeezing component 6b is provided inside the second swiping hole 6a. The mop head 3 can pass through the second swiping hole 6a. The second squeezing component 6b squeezes the wiping material 4 on the mop head 3 as it moves up and down, thereby moving, squeezing and squeezing the water out of the wiping material 4. As the mop head 3 moves downward into the second swiping hole 6a, the inner wall of the second swiping hole 6a supports the back plate of the mop head 3.

[0032] The first rinsing and squeezing device 5 has a first drainage channel D1 for transferring the water from the wiping material 4 to the outside of the inner washing tub 13, and the outlet end E2 of the water supply channel E is lower than the first drainage channel D1. The second rinsing and squeezing device 6 has a second drainage channel D2 for transferring the water squeezed off the wiping material 4 to the inside of the outer tub 11.

[0033] The working principle and process of this cleaning tool embodiment are as follows: like Figures 1-4 As shown, before cleaning: open the cover 102 and inject clean water into the clean water zone 1a through the water inlet 101. Cover the cover 102 to seal the top of the clean water zone 1a. Turn on the switch 7, and the clean water zone 1a supplies water to the cleaning zone 1b through the water supply channel E. When the water in the cleaning zone 1b exceeds the outlet E2 of the water supply channel E, the clean water zone 1a will no longer supply water to the cleaning zone 1b due to the sealing of the top of the clean water zone 1a and the action of atmospheric pressure. Therefore, the amount of water supplied each time is constant.

[0034] like Figures 6-10 As shown, the cleaning and initial wringing operation is as follows: After water supply is complete, switch 7 is turned off. The mop head 3 passes through the first swiping inlet 5a and enters the cleaning zone 1b. The mop head 3 moves up and down repeatedly, and the first wringing component 5b squeezes and cleans the wiping object 4. Each time, the wastewater squeezed off the wiping object 4 is transferred to the wastewater zone 1c through the first drain channel D1. This process is repeated multiple times until all the water in the cleaning zone 1b is removed. After a few more up and down movements of the mop head 3, the first wringing component 5b can initially wring out the water from the wiping object 4. In some scenarios, it is not necessary to transfer all the water from the cleaning zone 1b; only half of it needs to be transferred, as the wringing operation can be performed within the second swiping inlet 6a. Of course, the water in the cleaning zone can also be transferred to the outside through a drain valve, drain hole, pumping mechanism, or an absorbent component made of highly absorbent material. For the second cleaning, simply turn on switch 7 again and repeat the above steps.

[0035] Thoroughly squeeze out the water: such as Figures 11-12 As shown, after being washed and initially squeezed dry, the mop head 3 passes through the second water inlet 6a and enters the squeezing area 1c. The mop head 3 moves up and down repeatedly. The second support structure 8b supports the mop head 3. The second squeezing component 6b further squeezes the wiped object 4 dry. The water squeezed off the wiped object 4 is transferred to the sewage area 1c through the second drainage channel D2. After several repetitions, the wiped object 4 is fully squeezed dry.
