Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, and in particular relates to a cleaning mechanism. Background Technology

[0002] Chinese patent CN113974513A discloses a "Water-Saving Mop Cleaning Device," which includes a cleaning chamber, a water storage chamber, a squeezing mechanism, a water storage tank, and a transfer mechanism for transferring cleaning water from the water storage chamber to the water storage tank. In use, the cleaning water is first temporarily stored in the water storage tank before being poured, forming a delayed pouring structure. As the mop head moves downwards, the pouring time for the upper part of the object being wiped by the mop head is longer than the pouring time for the lower part. Even after the mop head stops moving, pouring continues for a period of time, thus distributing the cleaning water more evenly on the object being wiped by the mop head. While this achieves a water-saving effect, the cleaning effect on the mop head is not ideal. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a cleaning mechanism that uses a liquid storage section to collect the liquid squeezed out by the scraper section and return it to the flat mop, which can achieve the effect of water saving, and the cleaning effect of the flat mop is better.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a cleaning mechanism, including a mop bucket and a flat mop. The flat mop includes a mop handle and a mop board connected to the lower end of the mop handle, and a wiping material. The mop bucket has a cleaning chamber and a squeezing unit located above the cleaning chamber. The squeezing unit includes at least a scraper part and a liquid storage part. The liquid discharged by the scraper part and the wiping material of the flat mop can enter the liquid storage part. The squeezing unit forms at least a first flow path and a second flow path for the liquid discharged by the flat mop. The first flow path flows back to the wiping material of the flat mop, and the second flow path discharges out of the cleaning chamber.

[0005] Furthermore, the mop bucket also has a wastewater chamber, to which the second flow path delivers the wastewater.

[0006] Furthermore, the liquid flow rate of the first flow path is less than the liquid flow rate of the second flow path.

[0007] Furthermore, the first flow path also forms a branch flow path, which delivers the material to the cleaning chamber;

[0008] or,

[0009] The second flow path also forms a branch flow path, which delivers the material to the cleaning chamber.

[0010] Furthermore, the scraper section and the liquid storage section are linked together, or the scraper section and the liquid storage section are integrally connected.

[0011] Furthermore, the liquid storage section is flipped and connected to the mop bucket, and includes at least a first tank. The first tank is at least partially open on the side facing the flat mop to receive the liquid discharged from the flat mop by pulling and squeezing, and to form a first flow path for backflow to the wiping material of the flat mop. The liquid discharged by pulling and squeezing passes over the first tank and is discharged out of the cleaning chamber through a second flow path.

[0012] Furthermore, the liquid storage unit also includes a second tank connected to the first tank below it.

[0013] Furthermore, the squeezing unit also includes a first limiting structure for restricting the rotation of the liquid storage section. When the liquid storage section is engaged with the first limiting structure, the liquid in the first tank flows back to the mop, while the liquid in the second tank remains.

[0014] Furthermore, the first limiting structure is an inclined extension wall that can abut against the side wall of the liquid storage section; the inclined extension wall is inclined as a whole, and its top surface is inclined along the height direction of the cleaning mechanism.

[0015] Furthermore, it also includes a second limiting structure for restricting the rotation of the liquid storage section. When the liquid storage section is engaged with the second limiting structure, the liquid in the second tank is discharged to the side away from the mop.

[0016] Furthermore, the liquid storage section is provided with a rotating shaft, which can be flipped and connected to the mop bucket. The second limiting structure is an inclined limiting surface that can abut against the rotating shaft. The inclined limiting surface is located in the supporting part of the cleaning mechanism used to support the rotating shaft.

[0017] Furthermore, the scraper section forms a first liquid accumulation area, and the liquid storage section forms a second liquid accumulation area. The first liquid accumulation area is located upstream of the second liquid accumulation area. The liquid in the first liquid accumulation area forms a first flow path, and part of the liquid in the second flow path enters the second liquid accumulation area. The liquid in the second liquid accumulation area forms a branch flow path and flows into the cleaning chamber.

[0018] Furthermore, the liquid storage section has a lower baffle wall that extends into or tends to extend into the cleaning chamber, and an upper baffle wall. Liquid flowing through the second liquid accumulation area is discharged outward after passing over the upper baffle wall, and liquid in the second liquid accumulation area enters the cleaning chamber along the lower baffle wall.

[0019] Furthermore, the bottom wall of the second liquid accumulation zone is provided with a water outlet hole, and the liquid in the second liquid accumulation zone is discharged from the water outlet hole and enters the cleaning chamber along the barrier wall; the side of the second liquid accumulation zone close to the first liquid accumulation zone forms an inclined guide sidewall.

[0020] Furthermore, the highest point of liquid that the first liquid accumulation zone can hold is set vertically to the highest point of liquid that the second liquid accumulation zone can hold.

[0021] Furthermore, the liquid storage section is fixedly installed with the mop bucket, and the scraper section is fixedly installed with the mop bucket, or the scraper section is rotatably connected with the mop bucket.

[0022] The beneficial effects of this utility model are: 1) The liquid squeezed out by the scraper on the flat mop can flow back to the flat mop through the first flow path, which plays an auxiliary role in cleaning and improves the cleaning effect of the flat mop; 2) The liquid squeezed out by the scraper unit on the flat mop can enter the cleaning chamber through the branch flow path, which replenishes the liquid in the cleaning chamber used for cleaning the flat mop and avoids the liquid from being discharged too quickly due to excessive force between the flat mop and the scraper, thus improving the cleaning effect of the flat mop and saving water; 3) The liquid generated by the scraper unit and the pulling and pushing of the flat mop can flow back to the flat mop wiping material through the first flow path. 4) The liquid in the second accumulation zone can flow back to the cleaning chamber through the branch flow path, which can reduce the initial amount of cleaning liquid in the cleaning chamber and achieve water saving effect; 5) The first accumulation zone is formed by the scraper section. The liquid generated by the pulling and pushing of the flat mop and the scraper section directly enters the first accumulation zone, which has a better water storage effect. More liquid flows back to the flat mop through the first flow path, resulting in better water saving effect; 6) The first limiting structure prevents the liquid storage section from rotating excessively, ensuring that the scraper section can move upward smoothly during the upward pulling of the flat mop, and also ensuring that the scraper section can effectively squeeze the wiping material during the downward pushing of the flat mop, ensuring that the liquid is fully squeezed out.

Detailed Implementation

[0046] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0047] like Figure 1 As shown, a cleaning mechanism includes a mop bucket 1 and a flat mop 2. The flat mop 2 includes a mop handle, a mop board connected to the lower end of the mop handle, and a wiping agent. The mop bucket 1 has a cleaning chamber 11 and a wastewater chamber 12. The cleaning chamber 11 is used to clean the flat mop 2, specifically to clean the wiping agent on the flat mop 2. The wastewater chamber 12 is used to receive wastewater after cleaning the flat mop 2. Of course, the wastewater chamber 12 can also be set separately, that is, the wastewater chamber 12 is not part of the mop bucket 1. A scraping unit 3 is provided above the cleaning chamber 11. There is no restriction on whether the scraping unit 3 is set inside the cleaning chamber 11. The scraping unit 3 can be set at any position above the space corresponding to the cleaning chamber 11.

[0048] The squeezing unit 3 includes at least a scraper section 31 and a liquid storage section 32. Liquid squeezed and discharged by the scraper section 31 and the wiping material from the flat mop 2 can enter the liquid storage section 32. The squeezing unit 3 forms at least a first flow path 41 and a second flow path 42 for the liquid squeezed and discharged by the flat mop 2. The first flow path 41 returns to the wiping material from the flat mop 2, and the second flow path 42 discharges the liquid out of the cleaning chamber 11. Here, "outward" refers to the external container, such as a wastewater chamber 12, which exists independently of the mop bucket 1, relative to the cleaning chamber 11. In this embodiment, the second flow path 42 delivers the liquid to the wastewater chamber 12.

[0049] The first flow path 41 here includes a liquid flow path from the wiping material of the flat mop 2 towards the first tank 321, and also includes a liquid flow path from the first tank 321 or from the first tank 321 and the second tank 322 towards the wiping material of the flat mop 2. The flow path of the first flow path 41 is the first tank 321 and the scraper section 31, that is, the liquid in the first tank 321 must flow to the wiping material of the flat mop 2 through the scraper section 31.

[0050] like Figures 2-11 As shown, the scraper section 31 and the liquid storage section 32 are linked together; more specifically, the scraper section 31 and the liquid storage section 32 are integrally connected. Of course, in other embodiments, the scraper section 31 and the liquid storage section 32 can also be separate components. In this case, the scraper section 31 has a rotating shaft, which is rotatably connected to the mop bucket 1, and the liquid storage section 32 also has a rotating shaft, which is rotatably connected to the mop head 1. In this case, the scraper section 31 and the liquid storage section 32 are linked together, meaning that when the flat mop 2 moves the scraper section 31, the liquid storage section 32 also moves synchronously. More precisely, the liquid discharged by the flat mop 2 through the scraper section 31 flows into the liquid storage section 32.

[0051] The liquid storage section 32 is flipped and connected to the mop bucket 1 via a pivot 36. It includes a first tank 321 and a second tank 322 connected below the first tank 321. The first tank 321 is at least partially open on the side facing the flat mop 2, so as to receive the liquid that is pulled and squeezed out from the flat mop 2.

[0052] like Figure 4 , Figure 5 As shown, the top of the liquid storage section 32 is open. The first tank 321 includes a water-blocking surface 3211 opposite to the scraper section 11, and side walls on both sides of the water-blocking surface 3211. In other words, the first tank 321 is formed by the water-blocking surface 3211 and the side walls. When the scraper section 31 of the squeezing unit 3 interacts with the flat mop 2, the flat mop 2 blocks the open part of the first tank 321 opposite to the water-blocking surface 3211, and liquid can be accumulated in the first tank 321. Specifically... Figure 5 The first groove 321 is located between the plane where L1 is located and the plane where L2 is located.

[0053] Of course, such as Figure 12 , Figure 13 As shown, it is not necessarily the flat mop 2 that surrounds the side of the first tank 321 opposite to the water-blocking surface 3211. It can also be surrounded by a baffle 38 with a water leakage hole 381. The baffle 38 is integrally set on the side of the top opening of the liquid storage part 32 near the scraper part 31.

[0054] The liquid storage section 32 has an overall longitudinal section that is roughly V-shaped with a smooth bottom transition. The open side of the top of the liquid storage section 32 is integrally connected to the scraper section 31. Specifically, in this embodiment, the scraper section 31 extends from the open top of the liquid storage section 32 toward the direction of the flat mop 2, and the scraper section 31 extends along the entire length of the liquid storage section 32. The aforementioned water-blocking surface 3211 is the portion higher than the horizontal plane of the scraper section 31. In other words, when the liquid storage section 32 is placed approximately horizontally, the portion higher than the scraper section 31 is defined as the water-blocking surface 3211. The side wall height of the first tank 321 is flush with the water-blocking surface 3211. The height of the water-blocking surface 3211 should not be too large, so as to ensure that the liquid discharged by the interaction between the squeezing unit 3 and the flat mop 2 can form the first flow path 41 and the second flow path 42.

[0055] When the flat mop 2 is pulled down, as Figure 6 As shown, the flat mop 2 abuts against the scraper section 31, causing the scraper section 31 to rotate counterclockwise, which in turn causes the liquid storage section 32 to rotate counterclockwise. The liquid on the object being wiped by the flat mop 2 is squeezed by the scraper section 31 and forms a first flow path 41, entering the first tank 321 and the second tank 322. At the same time, the liquid in the first flow path 41 flows back to the object being wiped by the flat mop 2, cleaning the object on the upper part of the flat mop 2. Thus, even if the amount of liquid in the cleaning chamber 11 is limited, that is, when the flat mop 2 is fully inserted into the cleaning chamber 11 and the liquid cannot submerge the top of the flat mop 2, the liquid in the first flow path 41 can flow back to the flat mop 2 to clean the object on the upper part of the flat mop 2, achieving the purpose of water conservation.

[0056] The liquid that flows back to the flat mop 2 to wipe the object can flow out from the first tank 321, or it can flow out from the second tank 322 and the first tank 321. There is no specific limitation.

[0057] The liquid in the first flow path 41 flows entirely towards the wiping material of the flat mop 2. Of course, when the liquid flow rate of the first flow path 41 is large, the first flow path 41 also forms a branch flow path 43. This branch flow path 43 delivers the excess liquid after it has been absorbed by the wiping material of the flat mop 2 to the cleaning chamber 11. This prevents too much liquid in the cleaning chamber 11 from being delivered to the wastewater chamber 12 too quickly, thus extending the cleaning time of the flat mop 2 in the cleaning chamber 11. The liquid squeezed out also flows into the cleaning chamber 11, which also plays an auxiliary role in cleaning, resulting in a better cleaning effect on the flat mop 2.

[0058] The liquid formed by the wiping material and the scraper part 31 of the flat mop 2 is pulled and squeezed to form a second flow path 42, which passes through the first tank 321 and is discharged out of the cleaning chamber 11.

[0059] To limit the counterclockwise rotation range of the liquid storage section 32, the scraping unit 3 also includes a first limiting structure 51 for limiting the rotation of the liquid storage section 32, such as... Figure 9 , Figure 10 As shown, the first limiting structure 51 is an inclined extending wall that can abut against the side wall of the liquid storage section 32. If the extension direction of the partition 39 in the squeezing unit 3 is defined as the width direction of the mop bucket 1, then this inclined extending wall is inclined in two directions. It is inclined along the width direction of the mop bucket 1, specifically extending inclinedly away from the liquid storage section 32 along the width direction of the mop bucket 1. Furthermore, the top surface of the inclined extending wall is inclined along the height direction of the mop bucket 1, specifically extending inclinedly towards the top of the mop bucket 1 along the height direction of the mop bucket 1. When the liquid storage section 32 is engaged with the first limiting structure 51, the liquid in the first tank 321 flows back to the flat mop 2, while the liquid in the second tank 322 remains. In other words, not all the liquid in the second tank 322 flows back to the flat mop 2; at least some remains in the second tank 322.

[0060] An inclined surface 34 is formed on the bottom surface of the side wall of the liquid storage section 32, which can abut against the inclined extension wall. The inclined surface 34 slopes smoothly from the scraper section 31 to the bottom of the liquid storage section 32. The inclined extension wall ensures that the liquid storage section 32 does not rotate excessively counterclockwise, and ensures that the scraper section 31 can move upward smoothly and synchronously when the flat mop 2 is pulled upward. It also ensures that the scraper section 31 can effectively squeeze the wiping material when the flat mop 2 is pushed downward, ensuring that the liquid is fully squeezed out.

[0061] by Figure 10 Taking the direction shown as an example, in order to limit the clockwise rotation range of the liquid storage section 32, the squeezing unit 3 also includes a second limiting structure 52 for limiting the rotation of the liquid storage section 32. When the liquid storage section 32 is engaged with the second limiting structure 52, the liquid in the second tank 322 is discharged to the side away from the flat mop 2, so as to avoid the flat mop 2 not being able to completely dehydrate the wiped items due to the liquid accumulating in the second tank 322. The side wall of the liquid storage section 32 is provided with a rotating shaft 36, and the liquid storage section 32 is flipped and connected to the mop bucket 1 through the rotating shaft 36. The aforementioned second limiting structure 52 is an inclined limiting surface that can abut against the rotating shaft 36, such as... Figure 10 As shown, the inclined limiting surface is located on the support portion 331 of the mop bucket 1 for supporting the rotating shaft 36.

[0062] The supporting portion 331 extends over a considerable range, and the first limiting structure 51 is also provided on the supporting portion 331. Furthermore, the supporting portion 331 is also provided with a support plate 332 that abuts against the bottom arc portion of the liquid storage portion 32. This support plate 332 is integrally connected to the first limiting structure 51—an inclined extension wall. The support plate 332 provides support for the liquid storage portion 32, and its auxiliary support to the portion of the supporting portion 331 that abuts against the rotating shaft 36 ensures stable rotation of the liquid storage portion 32, resulting in a more stable overall structure.

[0063] In the initial state, that is, when the flat mop 2 is not pulled out, the liquid storage part 32 is roughly horizontal. When the flat mop 2 is pulled upward, it will cause the liquid storage part 32 to tilt. In order to restore the horizontal position of the liquid storage part 32 as soon as possible or stably, a reset member 53 is also provided. The reset member 53 abuts against the support part 331 of the mop bucket 1 and the liquid storage part 32 respectively, and is used to drive the liquid storage part 32 to reset. Specifically, it drives the liquid storage part 32 to rotate counterclockwise to reset.

[0064] To ensure the stability of the reset component 53, a limiting post 54 is also included. The limiting post 54 extends along the height direction of the mop bucket 1. The bottom of the limiting post 54 is fixedly connected to the support part 331. The reset component 53 is sleeved on the outside of the limiting post 54. A hole 35 is opened in the liquid storage part 32 for the limiting post 54 to pass through, so as not to interfere with the tilting and rotation of the liquid storage part 32.

[0065] like Figures 14-20 As shown, the scraper section 31 and the liquid storage section 32 are separately provided, and both are fixedly connected to the mop bucket 1. A portion of the scraper section 31 is recessed to form a first liquid accumulation area 311, as shown... Figure 17 As shown, the scraper part 31 has a bottom surface 313 and three side surfaces 314. The bottom surface 313 and the three side surfaces 314 form an open groove. The wiping material abuts against the open side of the groove, thereby forming a first liquid accumulation area 311. That is, the three side surfaces, the bottom surface of the scraper part 31, and the flat mop 2 cooperate to form the first liquid accumulation area 311. A portion of the liquid storage part 32 is recessed to form a second liquid accumulation area 324. The liquid in the first liquid accumulation area 311 forms a first flow path 41, and the liquid that crosses the first liquid accumulation area 311, that is, crosses the scraper part 31, forms a second flow path 42. A portion of the liquid in the second flow path 42 flows into the second liquid accumulation area 324. In other words, the second liquid accumulation area 324 is located downstream of the first liquid accumulation area 311. A portion of the liquid in the second flow path 42 flows directly into the cleaning chamber 11 across the liquid storage part 32. At the same time, the liquid in the second liquid accumulation area 324 forms a branch flow path 43 and also flows into the cleaning chamber 11.

[0066] Similarly, the first flow path 41 returns to the wiping material of the flat mop 2. Here, the first flow path 41 includes a liquid flow path from the wiping material of the flat mop 2 towards the first liquid accumulation area 311, and also includes a liquid flow path from the first liquid accumulation area 311 towards the wiping material of the flat mop 2. The flow path of the first flow path 41 is the first liquid accumulation area 311 and the scraper part 31, that is, the liquid in the first liquid accumulation area 311 must flow through the scraper part 31 towards the wiping material of the flat mop 2.

[0067] Specifically, the liquid storage section 32 includes an inclined guide sidewall 328 that cooperates with the scraper section 31, an upper blocking wall 326 that is at least partially opposite to the inclined guide sidewall 328, and a bottom wall with a water outlet 327. Here, the cooperation between the scraper section 31 and the guide sidewall 328 means that the guide sidewall 328 extends inclinedly from top to bottom away from the scraper section 31, and the upper end of the guide sidewall 328 is located below the top surface of the scraper section 31, so that liquid can enter the second liquid accumulation area 324 along the guide sidewall 328. A lower blocking wall 325 is connected below the upper blocking wall 326. The lower blocking wall 325 extends downward and at least partially extends into or tends to extend into the cleaning chamber 11, that is, the lower blocking wall 325 extends inclinedly from top to bottom towards the cleaning chamber 11. The inclined guide sidewall 328, the upper blocking wall 326, the bottom wall, and the sidewall connected to the upper blocking wall 326 enclose the second liquid accumulation area 324. The fact that the lower baffle wall 325 extends into the cleaning chamber 11 is meant to illustrate that the lower baffle wall 325 can guide liquid into the cleaning chamber 11, but it is not necessary for the lower baffle wall 325 to extend into the cleaning chamber 11. The cooperation between the scraper part 31 and the inclined guide sidewall 328 here means that the two are joined at this point. Liquid on the scraper part 31 enters the second liquid accumulation zone 324 through the inclined guide sidewall 328, which is located on the side of the second liquid accumulation zone 324 closest to the first liquid accumulation zone 311. The highest point of liquid accumulation in the first liquid accumulation zone 311 is vertically aligned with the highest point of liquid accumulation in the second liquid accumulation zone 324; specifically, the highest liquid level in the first liquid accumulation zone 311 is above the highest liquid level in the second liquid accumulation zone 324.

[0068] like Figures 18-20As shown, during the process of the scraper section 31 pushing and pulling the flat mop 2 to wipe the object, the liquid discharged from the object under pressure enters the first liquid accumulation area 311, forming the first flow path 41. This first flow path 41 can flow back to the object being wiped by the flat mop 2. That is, the liquid discharged from the object by pulling and pushing can enter the first liquid accumulation area 311 or be discharged from the first liquid accumulation area 311, and the above-mentioned entry and exit paths are the same or tend to be the same. Of course, the liquid entering the first liquid accumulation area 311 and being discharged from the first liquid accumulation area 311 can also occur simultaneously. The liquid overflowing the first accumulation zone 311 forms a second flow path 42. After passing the scraper section 31, the second flow path 42 enters the second accumulation zone 324 along the inclined guide sidewall 328. The liquid entering the second accumulation zone 324 can flow into the cleaning chamber 11 through the branch flow path 43. Specifically, it is discharged from the outlet hole 327 and then enters the cleaning chamber 11 along the lower baffle wall 325. Part of the liquid in the second flow path 42 passes over the upper baffle wall 326 and is discharged outward, in this embodiment, into the wastewater chamber 12. At this time, the branch flow path 43 is formed by the second flow path 42.

[0069] As described above, some of the liquid discharged by the squeezing and wiping unit 3 through the squeezing and wiping unit enters the second liquid accumulation area 324 through the second flow path 42 and then enters the cleaning chamber 11 through the branch flow path 43. Some of the fluid also enters the wastewater chamber 12 directly through the second flow path 42. Of course, when the amount of liquid in the cleaning chamber 11 is small, it can also enter the wastewater chamber 12 only through the second flow path 42; or, when the water outlet 327 on the bottom wall is blocked, the liquid in the second flow path 42 can also only enter the wastewater chamber 12; or, when the water outlet 327 on the bottom wall is small, most of the liquid in the wastewater chamber 12 enters the wastewater chamber 12. There are no specific restrictions.

[0070] During at least a portion of the time that the scraping unit 3 is squeezing the wiping material, the liquid flow rate of the first flow path 41 is less than the liquid flow rate of the second flow path 42, and the flow rate of the second flow path 42 flowing to the wastewater chamber 12 is greater than the flow rate of the branch flow path 43 flowing to the cleaning chamber 11. In other words, most of the liquid enters the wastewater chamber 12 through the second flow path 42, and relatively less liquid enters the cleaning chamber 11 through the branch flow path 43.

[0071] In this embodiment, the liquid storage section 32 is fixedly disposed with the mop bucket 1, and the scraper section 31 is fixedly disposed with the mop bucket 1. Of course, as... Figure 21 , Figure 22 As shown, the liquid storage section 32 can also be fixedly installed with the mop bucket 1, and the scraper section 31 can be rotatably connected to the mop bucket 1. In this case, the scraper section 31 has shafts 312 at both ends, and the scraper section 31 is rotatably connected to the mop bucket 1 through the shafts 312 on both sides. To avoid excessive rotation of the scraper section 31, a reset member 329 is provided between the scraper section 31 and the liquid storage section 32. When the scraper section 31 rotates counterclockwise under the drive of the flat mop 2 (towards...), the scraper section 31 rotates... Figure 21(Taking the direction shown as an example) When the scraper part 31 is rotated clockwise, the reset member 329 can pull the scraper part 31 clockwise to prevent it from rotating excessively counterclockwise and to prevent it from failing to reset. When the scraper part 31 rotates clockwise under the drive of the flat mop 2, the reset member 329 can push the scraper part 31 upward to drive the scraper part 31 to reset. Of course, in other embodiments, it is also possible that the scraper part 31 and the liquid storage part 32 are integrated and fixedly connected to the mop bucket 1.

[0072] In use, rotate the mop handle to a squeezeable state that is basically parallel to the mop plate. In this state, the flat mop plate and mop handle are inserted downwards into the cleaning chamber 11. The object being wiped and the scraper part 31 are pulled and pushed up and down. The liquid on the object being wiped is squeezed by the scraper part 31 and enters the first liquid accumulation area 311 through the first flow path 41. Of course, during the downward pulling of the flat mop 2, the liquid in the first liquid accumulation area 311 will also flow back to the object being wiped. More importantly, when the liquid in the cleaning chamber 11 cannot submerge the entire height of the object being wiped by the flat mop 2, the liquid in the first liquid accumulation area 311 flows back to the top of the object being wiped, providing auxiliary cleaning water for the part of the object that is not submerged in liquid; some liquid overflows the first liquid accumulation area 311 and then flows through... The liquid enters the second liquid accumulation zone 324 through the second flow path 42. Some of the liquid directly enters the wastewater chamber 12 through the second flow path 42. A portion of the liquid in the second liquid accumulation zone 324 enters the cleaning chamber 11 through the water outlet 327 on the bottom wall and the lower part of the inclined guide side wall 328 in the form of a branch flow path 43. This portion of liquid can continue to be used by the flat mop 2 to pull up and down in the cleaning chamber 11 for cleaning. Most of the liquid in the second flow path 42 enters the wastewater chamber 12 after passing the top surface of the upper baffle wall 326. When the amount of liquid remaining in the cleaning chamber 11 is small, the area of ​​the water outlet 327 on the bottom wall is small. Under the impact of pulling and pushing, the liquid in the second flow path 42 may directly enter the wastewater chamber 12, which is conducive to the emptying of the liquid in the cleaning chamber 11.

[0073] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
