Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning tools, and in particular to a flat mop cleaner 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:

[0005] 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.

[0006] 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.

[0007] 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.

[0008] In conclusion, the aforementioned cleaning tools for cleaning flat mops or sponge mops can be further improved. Utility Model Content

[0009] The technical problem to be solved by this utility model is to provide a flat mop cleaner that can achieve quantitative water supply, ensure that the water used to clean the mop is clean every time it is washed, and that the washing and wringing operations are independent of each other, in light of the above-mentioned existing technology.

[0010] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a flat mop cleaner, comprising a cleaning bucket and a mop, wherein the mop includes a mop head rotatably connected to the lower end of the mop handle, the mop head is provided with a wiping agent, and the mop head can be rotated to a cleaning position and a sweeping position; characterized in that: the cleaning bucket has a clean water area, a washing area and a wastewater area that are independent of each other, the clean water area and the washing area are at least partially located in the wastewater area, the clean water area is used to provide clean water to the washing area, and the top of the clean water area is closed; the clean water area and the washing area are connected by a water supply channel, the water supply channel is controlled to open and close by a switch, and the cleaning bucket... The device includes a first and a second wringer for the mop head to pass through. The first wringer corresponds to the cleaning area, and the mop head can enter the cleaning area after passing through the first wringer. The second wringer is located outside the cleaning area. The movement of the mop head through the first wringer is divided into at least two time periods. In the first time period, the movement of the mop head causes the switch to shift or rotate, so that the switch is in the closed state. In the second time period, the switch remains in the closed state throughout the movement of the mop head. The device also includes a first drainage channel or drainage switch for draining water from the cleaning area to the wastewater area.

[0011] In a further improvement, the first drainage channel is located on the first squeezing device. This first drainage channel directly transfers the water squeezed off the wiping material by the first squeezing device to the wastewater area. Each time, the wastewater squeezed off the wiping material is transferred to the outside of the cleaning area through the first drainage channel. This process is repeated multiple times until the water in the cleaning area is basically completely transferred, ensuring that the water in the cleaning area remains clean after the next water supply from the clean water area.

[0012] If it is a drain switch, after cleaning, turn on the drain switch to drain the water in the cleaning area directly. The drain switch usually needs to be installed at the bottom of the cleaning area.

[0013] As a choice of squeezing location, the aforementioned second spout squeezing device corresponds to the wastewater zone; the wastewater zone is provided with a support section that supports the mop head passing through the second spout squeezing device. Because the support section is raised within the wastewater zone, the area of ​​the wastewater zone below the support section becomes a true wastewater storage area. Water transferred through the second drainage channel from the mop head passing through the second spout squeezing device flows into the area of ​​the wastewater zone below the support platform, allowing for further squeezing.

[0014] As an optimal choice for the squeezing location, the cleaning bucket also has a separate squeezing area. The second wringer corresponds to this squeezing area, and the mop head can enter the squeezing area after passing through the second wringer. The squeezing area ensures that the squeezing operation is completed in an independent area, which is conducive to maintaining a basically water-free environment, allowing the wiped items to be squeezed out more thoroughly.

[0015] Further improvements include a second drainage channel to transfer water squeezed off the wiping material by the second spout wringing device to the wastewater area. The second drainage channel ensures that water squeezed off the wiping material is virtually eliminated from the wringing area, resulting in better wringing performance of the mop head. Preferably, a lifting protrusion is 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 material at the bottom of the mop head.

[0016] 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.

[0017] 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 only allows air to enter the space above the liquid surface of the water purification zone from the outside.

[0018] Preferably, the switch moves downward to close the water supply channel, and moves upward to open the water supply channel; to facilitate operation of the upward movement of the switch, the switch is provided with an easy-to-operate control end. To facilitate linkage with a mop, the switch is provided with a protrusion that engages with the downward-moving mop.

[0019] To further improve the user-friendliness of this cleaning tool, a linkage component is included. This component can be triggered by the mop entering the second wringer to open the switch. Thus, during the wringing process, the mop can pre-trigger the linkage component to open the switch, supplying water from the clean water zone to the washing zone for the next cleaning use without requiring additional operation of the switch.

[0020] To facilitate triggering of the linkage component by the mop, as an improvement, the aforementioned linkage component can move left and right. The linkage component has a connecting rod and a protruding trigger head mounted on the connecting rod. The trigger head extends to the second spout wringing device. The connecting rod is connected to a switch. As the trigger head moves towards the switch, the connecting rod causes the switch to move upwards. The aforementioned linkage component has a reasonable layout and can move smoothly, making it easier to open the switch. Specifically, the connecting rod and the switch are connected by a groove-protrusion fitting structure. The groove in the groove-protrusion fitting structure is located on one of the connecting rod and the switch, and the protrusion in the groove-protrusion fitting structure is located on the other of the connecting rod and the switch. The protrusion inserts into the groove and can slide along the groove.

[0021] Preferably, the first spout squeezing device includes a first spout frame with a first spout hole, and a first squeezing component is provided inside the first spout hole. The first squeezing component can be a squeezing scraper, a squeezing protrusion, a cleaning roller, or a water-absorbing mechanism. The first squeezing component squeezes the wiping material on the up-and-down moving mop head, thereby moving, squeezing, and squeezing the wiping material. The second spout squeezing device includes a second spout frame with a second spout hole, and a second squeezing component is provided inside the second spout hole. The second squeezing component squeezes the wiping material on the up-and-down moving mop head, thereby moving, squeezing, and squeezing the wiping material. A mounting frame is connected to the top opening of the cleaning bucket, and the first and second spout squeezing devices are mounted on the mounting frame. The first and second spout squeezing devices are pre-assembled onto the mounting frame, and then the mounting frame is assembled onto the opening of the cleaning bucket, making assembly convenient. The first rinsing hole does not need to have a wringing component; the water in the cleaning area can be absorbed by the wiping material or another adsorption component on the mop head.

[0022] Compared with the prior art, the advantages of this utility model are as follows: During cleaning, when the switch is turned on, 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 stops supplying water, thus completing the quantitative water supply operation. After the quantitative water supply is completed, the mop head enters the cleaning zone through the first spout squeezing device and moves up and down. The clean water in the cleaning zone cleans the wiping object. In the first time period, that is, during the time when the mop head first moves to the bottom, the movement of the mop head causes the switch to shift or rotate, so that the switch is in the closed state. After cleaning, the water in the cleaning zone can be drained, such as by setting a drain switch on the cleaning zone. In the second time period, that is, the time interval after the first time period, during the movement of the mop head... The switch remains closed, and the mop head moves back and forth, using the first wringer to scrape and clean the surface. After cleaning, the dirty water in the cleaning area is drained to the wastewater area via the first drain channel or drain switch. Because the switch remains closed, the water supply channel is not supplied during drainage. After cleaning, the mop head is removed from the first wringer and inserted into the second wringer, moving up and down repeatedly. The second wringer applies reciprocating pressure to thoroughly squeeze the surface dry. This mop cleaner ensures that the water used for each mop cleaning is clean and supplied in a measured amount, resulting in better cleaning and water conservation. The wringing operation is performed in an area separate from and outside the cleaning area, without interference, resulting in better drying compared to wringing in the cleaning area.

[0039] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0040] like Figures 1-15 The figure shown is a preferred embodiment of the present invention.

[0041] A flat mop cleaner 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. The mop head 3 is provided with a wiping material 4, which can be a microfiber cloth or foam. The mop head 3 can be rotated to a cleaning position and a sweeping position.

[0042] The cleaning bucket 1 has three independent zones: a clean water zone 1a, a washing zone 1b, and a wastewater zone 1d. The clean water zone 1a and washing zone 1b are at least partially located within the wastewater zone 1d. The clean water zone 1a provides clean water to the washing zone 1b, and its top is closed. While water is supplied to the washing zone 1b via the water supply channel E, air enters the space above the liquid surface in the clean water zone 1a through the water supply channel E until the water in the washing zone 1b submerges the outlet E2 or inlet E1 of the water supply channel E. The clean water zone 1a and washing zone 1b are connected by the water supply channel E, which is controlled by a switch 7. Moving the switch 7 downwards closes the water supply channel E, and moving the switch 7 upwards opens the water supply channel E. The switch 7 has an easy-to-operate operating end 71 and a protrusion 72 that engages with the downward-moving mop.

[0043] The cleaning bucket 1 is equipped with a first wringer 5 and a second wringer 6 for the mop head 3 to pass through. The first wringer 5 corresponds to the cleaning area 1b. The mop head 3 can enter the cleaning area 1b after passing through the first wringer 5. The second wringer 6 is located outside the cleaning area 1b. The movement of the mop head 3 through the first wringer 5 is divided into at least two time periods. The first time period is when the mop head 3 first moves down to the bottom of the cleaning area. The movement of the mop head 3 causes the switch 7 to move or rotate, so that the switch 7 is in the closed state. The second time period is the time period when the mop head 3 moves up and down in the cleaning area 1b, excluding the first time period. During the movement of the mop head 3, the switch 7 is always in the closed state.

[0044] It also includes a first drainage channel D1 for draining water from the cleaning area 1b to the sewage area 1d. The first drainage channel D1 is provided on the first squeegee water squeezing device 5. The first drainage channel D1 directly transfers the water on the wiping material 4 squeezed down by the first squeegee water squeezing device 5 to the sewage area 1d.

[0045] The first drainage channel D1 can also be replaced by a drain switch. After cleaning, open the drain switch to drain the water in the cleaning area directly. The drain switch is generally located at the bottom of the cleaning area. The drain switch can adopt a switch structure similar to that in this embodiment.

[0046] It also includes a second drainage channel D2 for transferring water from the wiping material 4 squeezed out by the second nozzle squeezing device 6 to the sewage area.

[0047] The cleaning bucket 1 also has a separate squeezing area 1c. The second spout squeezing device 6 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.

[0048] It also includes a linkage component 8, which can be triggered by a mop entering the second spout squeezing device 6 to open the switch 7. The linkage component 8 can move left and right. The linkage component 8 has a connecting rod 81 and a trigger head 82 that is provided on the connecting rod 81 and protrudes outward. The trigger head 82 extends to the second spout squeezing device 6, and the connecting rod 81 is connected to the switch 7. The connecting rod 81 moves towards the switch 7 with the trigger head, and the connecting rod 81 drives the switch 7 to move upward. The transmission connection between the connecting rod 81 and the switch can be that the connecting rod 81 and the switch 7 are connected by a groove-protrusion mating structure. The groove 8a in the groove-protrusion mating structure is provided on the trigger component, and the protrusion 8b in the groove-protrusion mating structure is provided on the switch 7. The protrusion 8b is inserted into the groove 8a and can slide along the groove 8a.

[0049] The cleaning tank 1 includes an outer tank 11, a clean water tank 12, and a washing tank 13. The clean water tank 12 constitutes a clean water zone 1a, and the washing tank 13 constitutes a washing zone 1b. The outer tank 11 is divided into two independent areas by a partition 14: one is a wastewater zone 1d, and the other is a squeezing zone 1c. The clean water tank 12 and the washing tank 13 are located in the wastewater zone 1d. The top of the clean water tank 12 is sealed with a lid 10. A sealing ring 103 is provided between the top port of the clean water zone 1a and the lid 10. The lid 10 has a water inlet 101, which is sealed with a cap 102.

[0050] The first swiping and squeezing device 5 includes a first swiping frame 9a with a first swiping hole 5a, and a first squeezing component 5b is provided in the first swiping hole 5a; the second swiping and squeezing device 6 includes a second swiping frame 9b with a second swiping hole 6a, and a second squeezing component 6b is provided in the second swiping hole 6a; the top opening of the cleaning bucket 11 is connected to a mounting frame 9, and the first swiping and squeezing device 5 and the second swiping and squeezing device 6 are mounted on the mounting frame 9.

[0051] The working principle and process of this cleaning tool embodiment are as follows:

[0052] like Figures 1-5 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.

[0053] like Figures 6-10As shown, the cleaning and initial wringing operation is as follows: After water supply is completed, switch 7 is turned off. The mop head 3 passes through the first swiping inlet 5a and enters the cleaning zone 1b. During the first time period, i.e., the time when the mop head 3 first moves to the bottom, the movement of the mop head 3 causes the switch 4 to move down, so that the switch 7 is in the closed state. During the second time period, i.e., the time interval after the first time period, the switch 7 is always in the closed state during the movement of the mop head 3. 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 drainage channel D1. This process is repeated multiple times until the water in the cleaning zone 1b is completely transferred. After moving the mop head 3 up and down a few more times, the first wringing component 5b can initially squeeze the water off the wiping object 4. In some scenarios, it is not necessary to transfer all the water in the cleaning zone 1b; only half of it needs to be transferred because the wringing operation can be carried out in the second swiping inlet 6a, and initial wringing is not required. For the second cleaning, simply turn on switch 7 again and repeat the above steps.

[0054] 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, and 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.

[0055] In summary, this cleaning tool can automatically supply a measured amount of water for each cleaning session, ensuring that only clean water is used to wash the mop each time. This results in better cleaning performance and water conservation. The amount of water in the clean water zone 1a can be used for multiple measured clean water cleanings of the mop. After cleaning and initial wringing are completed in the washing zone 1b, some customers may feel that the mop 4 still has too much moisture. In this case, further wringing can be done in the wringing zone 1d to meet customer needs. Of course, thorough wringing is not a mandatory option for customers; it can be used as needed.

[0056] like Figure 16 The following is a second embodiment of the present invention.

[0057] The difference between this embodiment and the first embodiment is that: no independent squeezing area is set up, and the second squeezing device 6 corresponds to the sewage area 1d; the sewage area 1d is provided with a support part 111 that supports the mop head 3 passing through the second squeezing device 6.

[0058] Compared with the first embodiment, the location of the thorough squeezing operation is different in this embodiment.

[0059] It should be noted that in the description of this embodiment, the terms "front," "rear," "left," "right," "up," "down," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are merely for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
