Description

Technical Field

[0001] This utility model belongs to the field of cleaning tool technology, and in particular relates to a squeegee mechanism and a cleaning device for use in cleaning devices. 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.

[0003] Chinese patent CN217447662U discloses a "Combination Cleaning Tool of a Water-Containing Squeezing Mop and Bucket," which includes a mop board for wiping materials and a wringer with a spout. The wringer is connected to a container for storing water, and the water flowing from the outlet of this container flows to the wiping materials on the mop board. The outlet of the container is located below the inlet, allowing external water to enter the container through the inlet and flow out through the outlet to the wiping materials. In this structure, the container and the wiping component are two independent parts, and the liquid in the container is supplied from the outside, thus failing to achieve water conservation and only allowing for a reduction in the bucket's volume. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a squeegee mechanism and a cleaning device for a cleaning device. It uses a liquid storage tank to collect the liquid squeezed out by the squeegee and return it to the cleaning component, which can achieve the effect of water saving and the cleaning effect of the cleaning component is better.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a wiping mechanism for a cleaning device, comprising:

[0006] The scraper section, located in the cleaning device, can abut against the cleaning component and is used to squeeze and clean the cleaning component when it is pulled up and down.

[0007] A liquid storage tank is disposed near the scraper section and can rotate relative to the cleaning device. It has at least a first tank body located above the horizontal height of the scraper section.

[0008] The first tank body can be formed with the baffle to create a first liquid storage area.

[0009] Furthermore, the baffle is part of the cleaning component, or the baffle is a baffle with a water outlet, which is located at the top opening of the liquid storage tank, near the scraper section.

[0010] Furthermore, the first tank includes a water-blocking surface and liquid storage tank sidewalls located on both sides of the water-blocking surface, wherein the water-blocking surface is located on the side opposite to the top opening of the liquid storage tank.

[0011] Furthermore, the liquid storage tank and the scraper section are linked together; or, the liquid storage tank and the scraper section are integrally formed.

[0012] Furthermore, the liquid discharged by the cleaning component through the pulling and squeezing mechanism can enter or exit the first liquid storage area, and the liquid's entry and exit paths are the same or tend to be the same.

[0013] Furthermore, the liquid storage tank also has a second tank body located below the horizontal height of the scraper section, and a second liquid storage area is formed in the second tank body that is connected to the first liquid storage area.

[0014] Furthermore, the liquid storage tank has at least a liquid storage state and a backflow state;

[0015] In the liquid storage state, the cleaning component is pulled downward relative to the scraper part, and the scraper part squeezes the cleaning component. The liquid squeezed out by the cleaning component enters the first liquid storage area / first liquid storage area and second liquid storage area of ​​the liquid storage tank.

[0016] In the backflow state, the cleaning component is pulled downward relative to the scraper section, and the liquid storage tank flips with the scraper section, so the liquid in the first liquid storage area flows back to the cleaning component;

[0017] The liquid flow paths in the liquid storage state and the reflux state are the same or tend to be the same.

[0018] Furthermore, the liquid storage tank has a draining state. When the liquid storage tank enters the draining state, the liquid in the second liquid storage area / first liquid storage area and second liquid storage area of ​​the liquid storage tank is discharged to the side away from the cleaning component.

[0019] Furthermore, it also includes a first limiting structure for restricting the rotation of the liquid storage tank;

[0020] When the liquid storage tank is engaged with the first limiting structure, the liquid in the first liquid storage area flows back to the cleaning component, and at least part of the liquid in the second liquid storage area remains in the second tank.

[0021] Furthermore, the first limiting structure is an inclined extension wall that can abut against the side wall of the liquid storage tank.

[0022] Furthermore, the inclined extension wall is inclined as a whole, with its top surface inclined along the height direction of the cleaning device.

[0023] Furthermore, it also includes a second limiting structure for restricting the rotation of the liquid storage tank;

[0024] When the liquid storage tank is engaged with the second limiting structure, the liquid in the second liquid storage area is discharged to the side away from the cleaning component.

[0025] Furthermore, the liquid storage tank is provided with a rotating shaft, which can be flipped and connected to the cleaning device. 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 device used to support the rotating shaft.

[0026] Furthermore, the top of the liquid storage tank is open, and one side of the opening is integrally connected to the scraper section.

[0027] Furthermore, the scraper extends from the top opening of the liquid storage tank towards the cleaning component, and the scraper extends along the entire length of the liquid storage tank, with one end facing the cleaning component forming an inclined scraping surface; the liquid storage tank is provided with multiple intervals, which are respectively connected to the scraper, the inner wall of the liquid storage tank, and the water-blocking surface.

[0028] Furthermore, it also includes a reset component, which abuts against the cleaning device and the liquid storage tank respectively, for driving the liquid storage tank to rotate and reset from the draining state; it also includes a limiting post, which extends along the height direction of the cleaning device, the reset component is sleeved on the outside of the limiting post, and the liquid storage tank has a hole for the limiting post to pass through.

[0029] This utility model also discloses a cleaning device, which includes at least a second container for cleaning components, the second container being provided with the aforementioned squeegee mechanism.

[0030] Furthermore, it also includes a third container surrounding the second container, into which the liquid discharged from the storage tank enters the third container when the storage tank enters the discharge state.

[0031] Furthermore, it also includes a first container for storing clean liquid, the first container having an inlet that can be sealed with a sealing component, and the first container and the second container being at least partially located within the third container.

[0032] The beneficial effects of this utility model are: 1) The liquid squeezed out by the scraper on the cleaning component can enter the first tank of the liquid storage tank, and this part of the liquid can flow back to the cleaning component, playing an auxiliary cleaning role and improving the cleaning effect on the cleaning component; 2) The liquid storage tank can accumulate the liquid squeezed out by the scraper, reducing the initial amount of cleaning liquid in the second container and achieving water saving; 3) The liquid storage tank and the scraper are interconnected, and the liquid generated by the scraper squeezing the cleaning component can directly enter the liquid storage tank, resulting in better water storage; 4) The liquid storage tank and the scraper are integrated, with a simple overall structure, eliminating the need for separate connection structures with the second container and simplifying the assembly structure. The cleaning components and the scraper interact to discharge liquid directly into the storage tank, resulting in a larger liquid volume and better cleaning effect on the items wiped by the cleaning components; 5) The liquid flowing back from the storage tank to the cleaning components is relatively evenly distributed, resulting in excellent cleaning effect; 6) The first limiting structure prevents the storage tank from rotating excessively, ensuring that the cleaning components can smoothly drive the scraper to move upward synchronously during the upward pulling process, and also ensuring that the scraper can effectively squeeze the items wiped during the downward pushing process, ensuring sufficient squeezing and discharge of liquid; 7) The layout design of the first, second, and third containers makes the overall size of the cleaning device small and the structure stable.

Detailed Implementation

[0051] 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.

[0052] like Figures 1-3 As shown, a squeegee mechanism for a cleaning device includes a squeegee portion 11 disposed on the cleaning device 1 and a liquid storage tank 3 disposed near the squeegee portion 11. The squeegee portion 11 can abut against the cleaning component 2 and is used to squeeze and clean the cleaning component 2 when it is pulled up and down. The liquid storage tank 3 can rotate relative to the cleaning device 1, and the liquid storage tank 3 has at least a first tank body 31 located above the horizontal height of the squeegee portion 11. The first tank body 31 can be formed with a baffle to form a first liquid storage area 311.

[0053] The scraper section 11 and the liquid storage tank 3 can be either separate or integrated. In the case where they are separate, such as... Figure 16 , Figure 17 As shown, the scraper part 11 has a rotating shaft 112, which is rotatably connected to the cleaning device 1. The liquid storage tank 3 also has a rotating shaft 34, which is rotatably connected to the cleaning device 1. In this case, the movements of the scraper part 11 and the liquid storage tank 3 can be independent of each other or linked together. Of course, when the two are set separately, the scraper part 11 can be fixedly connected to the cleaning device 1, while only the liquid storage tank 3 is rotatably connected to the cleaning device 1 through the rotating shaft 34.

[0054] The baffle can be cleaning component 2, or other structures; there are no specific limitations. For example... Figure 14 , Figure 15 As shown, the baffle is a baffle 38 with a water outlet 381, which is located at the top opening 27 of the liquid storage tank 3, near the scraper part 11. In this embodiment, the baffle is described in detail as a cleaning component 2, which is a flat mop.

[0055] In this embodiment, the liquid storage tank 3 and the scraper part 11 are linked together, that is, the scraper part 11 and the liquid storage tank 3 rotate together. More specifically, the liquid storage tank 3 and the scraper part 11 are integrally formed.

[0056] like Figures 4-6As shown, the top of the liquid storage tank 3 has an open opening 37. The first tank body 31 includes a water-blocking surface 312 and side walls 33 of the liquid storage tank 3 located on both sides of the water-blocking surface 312. The water-blocking surface 312 is located on the side opposite to the open opening 37 at the top of the liquid storage tank 3. In other words, the first tank body 31 is formed by the water-blocking surface 312 and the side walls 33 of the liquid storage tank 3.

[0057] When the baffle is the cleaning component 2, the cleaning component 2 and the water-retaining surface 312 and side walls 33 of the liquid storage tank 3 cooperate to form a first liquid storage area 311 that can accumulate liquid. During the up-and-down pulling of the cleaning component 2, liquid is always accumulated in the first liquid storage area 311. When the baffle is the baffle 38 with a water outlet 381, since the area of ​​the water outlet 381 is relatively small, the baffle 38 and the water-retaining surface 312 and side walls 33 of the liquid storage tank 3 can still cooperate to form the first liquid storage area 311.

[0058] by Figure 6 Taking the example shown, the baffle is the cleaning component 2, which, together with the water-blocking surface 312 and the side wall 33 of the liquid storage tank, forms the first liquid storage area 311. In other words, the cleaning component 3 and the first tank 31 cooperate to form the first liquid storage area 311, that is, the area between the plane where L1 and L2 are located in the figure is the first liquid storage area 311. The liquid discharged by the cleaning component 2 during the pulling and squeezing process can enter the first liquid storage area 311. Specifically, during the downward pulling process of the cleaning component 2, the liquid on the object being wiped by the cleaning component 2 is squeezed into the first liquid storage area 311. At the same time, the liquid in the first liquid storage area 311 can also be discharged to the cleaning component 2. The paths for the liquid to enter and exit the first liquid storage area 311 are the same or tend to be the same.

[0059] Specifically, when cleaning component 2 is pulled down, such as... Figure 7 As shown, the cleaning component 2 abuts against the scraper part 11, causing the scraper part 11 to rotate counterclockwise, which in turn causes the liquid storage tank 3 to rotate counterclockwise. The liquid on the object being wiped by the cleaning component 2 is squeezed by the scraper part 11 and enters the first liquid storage area 311. When the amount of liquid in the cleaning device 1 is limited, that is, when the cleaning component 2 is fully inserted into the cleaning device 1 but the liquid cannot submerge the top of the cleaning component 2, the liquid in the first liquid storage area 311 can flow back to the cleaning component 2 to clean the object being wiped on the upper part of the cleaning component 2. Of course, this does not mean that the liquid in the first liquid storage area 311 will only flow back to the upper part of the object being wiped by the cleaning component 2. During the up and down pulling of the cleaning component 2, the liquid in the first liquid storage area 311 will flow back to the object being wiped by the cleaning component 2.

[0060] To increase the liquid storage volume of the storage tank 3, the storage tank 3 also has a second tank body 32 located below the horizontal height of the scraper section 11. It should be noted that the horizontal height of the scraper section 11 refers to a general range. The scraper section 11 has a certain height, which can be the horizontal height of the top of the scraper section 11, the horizontal height of the middle of the scraper section 11, or the horizontal height of the scraper section 11 as a whole after abstracting it into a plane. There is no specific limitation. A second liquid storage area 321 is formed within the second tank body 32, which is connected to the first liquid storage area 311.

[0061] Specifically, such as Figure 5 As shown, the liquid storage tank 3 is an open-top tank with a roughly V-shaped longitudinal section and a smooth bottom transition. One side of the top opening 37 of the liquid storage tank 3 is integrally connected to the scraper part 11. Specifically, in this embodiment, the scraper part 11 extends from the top opening 37 of the liquid storage tank 3 towards the cleaning component 2, and extends along the entire length of the liquid storage tank 3. An inclined scraping surface 111 is formed at the end of the scraper part 11 facing the cleaning component 2. A water-retaining surface 312 is formed on the side of the top opening 37 of the liquid storage tank 3 away from the cleaning component 2, which is higher than the horizontal plane of the scraper part 11. In other words, when the liquid storage tank 3 is placed roughly horizontally, the part higher than the scraper part 11 is defined as the water-retaining surface 312. The height of the side wall 33 of the liquid storage tank 3 is flush with the water-retaining surface 312.

[0062] To increase the strength of the liquid storage tank 3 and to ensure a relatively balanced amount of liquid received by the cleaning component 2 in the width direction when the liquid in the liquid storage tank 3 flows back to the cleaning component 2, multiple spacers 35 are provided inside the liquid storage tank 3. These spacers are evenly spaced along the width direction of the liquid storage tank 3, and each spacer 35 is connected to the upper surface of the scraper part 11, the inner wall of the liquid storage tank 3, and the inner side wall of the water-retaining surface 312 facing the liquid storage tank 3. Alternatively, the spacers 35 may only be connected to the inner wall of the liquid storage tank 3, or only to the inner wall of the liquid storage tank 3 and the inner side wall of the water-retaining surface 312; there is no specific limitation.

[0063] The liquid storage tank 3 has three states: a liquid storage state, a liquid discharge state, and a backflow state. Taking the structure of the liquid storage tank 3 consisting only of the first tank body 31 as an example, when the cleaning component 2 is pulled downwards, the scraper part 11 squeezes the cleaning component 2, and the liquid squeezed out from the cleaning component 2 enters the first liquid storage area 311 of the liquid storage tank 3 and accumulates in the first liquid storage area 311. This is the liquid storage state of the liquid storage tank 3. In the liquid storage state, as the cleaning component 2 is pulled downwards relative to the scraper part 11, it drives the scraper part 11 to rotate, which in turn drives the liquid storage tank 3 to flip. The liquid in the first liquid storage area 311 flows back to the cleaning component 2. This is the backflow state. Of course, the backflow state and the liquid storage state are not completely independent. The two states can exist simultaneously, and the flow path of the liquid in the liquid storage state and the backflow state is the same or tends to be the same.

[0064] When the liquid storage tank 3 enters the draining state, the liquid in the first liquid storage area 311 of the liquid storage tank 3 is discharged to the side away from the cleaning component 2.

[0065] Taking the structure of the liquid storage tank 3, which includes a first tank body 31 and a second tank body 32, as an example, when the cleaning component 2 is pulled downwards, the scraper part 11 squeezes the cleaning component 2, and the liquid squeezed out from the cleaning component 2 enters the first liquid storage area 311 and the second liquid storage area 321 of the liquid storage tank 3, and accumulates in the first liquid storage area 311 and the second liquid storage area 321. This is the liquid storage state of the liquid storage tank 3. In the liquid storage state, since the cleaning component 2 is pulled downwards relative to the scraper part 11, it drives the scraper part 11 to rotate, which in turn drives the liquid storage tank 3 to flip. The liquid in the first liquid storage area 311 flows back to the cleaning component 2. This is the backflow state. Of course, the backflow state and the liquid storage state are not completely independent. The two states can exist simultaneously. Of course, the liquid in the second liquid storage area 321 can also flow back to the cleaning component 2.

[0066] When the liquid storage tank 3 enters the draining state, the liquid in the first liquid storage area 311 and the second liquid storage area 321 of the liquid storage tank 3 is discharged to the side away from the cleaning component 2, or in other words, the liquid in the second liquid storage area 321 of the liquid storage tank 3 is discharged to the side away from the cleaning component 2.

[0067] The purpose of setting the liquid storage tank 3 to drain the liquid in the liquid storage tank 3 is to prevent the liquid remaining in the liquid storage tank 3 from flowing to the cleaning component 2 during the final step of the cleaning process of the cleaning component 2, which would prevent the component from being completely drained.

[0068] by Figure 7 Taking the direction shown as an example, in order to limit the range of counterclockwise rotation of the liquid storage tank 3, the wiping mechanism also includes a first limiting structure 41 for limiting the rotation of the liquid storage tank 3. When the liquid storage tank 3 is engaged with the first limiting structure 41, the liquid in the first liquid storage area 311 flows back to the cleaning component 2, and the liquid in the second liquid storage area 321 remains in the second tank 32. Specifically, as shown... Figure 11 , Figure 12 As shown, the first limiting structure 41 is an inclined extension wall that can abut against the side wall of the liquid storage tank 3. If the extension direction of the intermediate partition 35 of the wiping mechanism is defined as the width direction of the cleaning device 1, then the inclined extension wall is inclined in two directions. Specifically, it is inclined along the width direction of the cleaning device 1, extending towards the side away from the liquid storage tank 3. Furthermore, the top surface of the inclined extension wall is inclined along the height direction of the cleaning device 1, specifically extending towards the side where the top of the cleaning device 1 is located.

[0069] An inclined surface 331 is formed on the bottom surface of the side wall 33 of the liquid storage tank 3, which can abut against the inclined extension wall. The inclined surface 331 slopes smoothly from the scraper part 11 to the bottom of the liquid storage tank 3. The inclined extension wall ensures that the liquid storage tank 3 will not rotate excessively counterclockwise, ensuring that the cleaning part 2 can smoothly drive the scraper part 11 to move upward synchronously during the upward pulling process, and also ensuring that the scraper part 11 can effectively squeeze the wiping material during the downward pushing process of the cleaning part 2, ensuring that the liquid is fully squeezed out.

[0070] by Figure 8 Taking the direction shown as an example, in order to limit the clockwise rotation range of the liquid storage tank 3, the wiping mechanism also includes a second limiting structure 42 for limiting the rotation of the liquid storage tank 3. When the liquid storage tank 3 is engaged with the second limiting structure 42, the liquid in the second liquid storage area 321 is discharged to the side away from the cleaning component 2. The side wall 33 of the liquid storage tank 3 is provided with a rotating shaft 34. The liquid storage tank 3 is flipped and connected to the cleaning device 1 through the rotating shaft 34. The aforementioned second limiting structure 42 is an inclined limiting surface that can abut against the rotating shaft 34, such as... Figure 12 As shown, the inclined limiting surface is located on the support portion 14 of the cleaning device 1 for supporting the rotating shaft 34.

[0071] The supporting part 14 extends over a considerable range, and the first limiting structure 41 is also provided on the supporting part 14. Furthermore, the supporting part 14 is also provided with a support plate 141 that abuts against the bottom arc portion of the liquid storage tank 3. This support plate 141 is integrally connected to the first limiting structure 41 – the inclined extension wall. The support plate 141 provides support for the liquid storage tank 31, and its auxiliary support on the supporting part 14 abuts against the rotating shaft 34, allowing the liquid storage tank 31 to rotate stably, thus making the overall structure more stable.

[0072] In the initial state, that is, without the cleaning component 2 being pulled out, the liquid storage tank 3 is roughly horizontal. During the upward pulling of the cleaning component 2, the liquid storage tank 3 will tilt. In order to restore the liquid storage tank 3 to its horizontal position as quickly or stably as possible, a reset component 51 is also provided. The reset component 51 abuts against the support part 14 of the cleaning device 1 and the liquid storage tank 3 respectively, and is used to drive the liquid storage tank 3 to reset. Specifically, it drives the liquid storage tank 3 to rotate counterclockwise to reset, that is, the reset component 51 drives the liquid storage tank 3 to rotate and reset from the draining state.

[0073] To ensure the stability of the reset component 51, a limiting post 52 is also included. The limiting post 52 extends along the height direction of the cleaning device 1. The bottom of the limiting post 52 is fixedly connected to the support part 14. The reset component 51 is sleeved on the outside of the limiting post 52. A hole 36 is opened in the liquid storage tank 3 for the limiting post 52 to pass through, so as not to interfere with the tilting and rotation of the liquid storage tank 3.

[0074] A cleaning device includes a first container 15 for storing cleaning liquid, a second container 12 for cleaning a cleaning component 2, and a third container 13. The second container 12 has a water transfer channel 121 at its upper part, and the third container 13 receives liquid discharged from the water transfer channel 121 of the second container 12. The first container 15 and the second container 12 are at least partially located within the third container 13; in other words, the third container 13 surrounds the outer periphery of the first container 15 and the second container 12. A squeegee mechanism is provided on the second container 12 near the water transfer channel 121, and a brushing structure 16, which can be brush bristles, is provided above the squeegee mechanism. In this embodiment, the water transfer channel 121 is a structure with multiple openings formed in a support portion 141. When the liquid storage tank 3 enters the draining state, the discharged liquid is discharged to the side away from the cleaning component 2, i.e., discharged into the third container 13. Rotating shafts 34 are provided on both sides of the liquid storage tank 3, which are pivotally connected to the second container 12 via these shafts. Specifically, the support portion 14 is located on the second container 12. To facilitate the delivery of clean liquid to the first container 15, an inlet is formed at the top of the first container 15. This inlet can be sealed with a sealing component, thereby making the first container 15 relatively sealed.

[0075] In use, insert the cleaning part 2 downwards into the second container 12, and rotate the scraper part 11 counterclockwise (towards...). Figure 2(Using the direction shown as an example) As the cleaning component 2 rotates, the liquid storage tank 3 also rotates counterclockwise (in other embodiments, the scraper part 11 may remain relatively stationary, and the liquid storage tank 3 may be flipped by the wiping material of the cleaning component 2). When the wiping material of the cleaning component 2 is soaked in liquid, during its downward pulling process, the liquid on the wiping material is squeezed by the scraper part 11 and flows along the scraper part 11 to the liquid storage tank 3, so that the liquid storage tank 3 enters the liquid storage state. Some of the liquid overflows the first tank body 31 of the liquid storage tank 3 and enters the third container 13 through the water transfer channel 121. During the downward pulling process of the cleaning component 2, because the cleaning component 2 blocks one side of the liquid storage tank 3, the liquid in the first liquid storage area 311 of the liquid storage tank 3 will also flow back to the wiping material. More importantly... Yes, when the liquid in the second container 12 cannot submerge the entire height of the object being wiped by the cleaning component 2, the liquid in the reservoir 3 flows back to the top of the object being wiped, providing auxiliary cleaning water for the part of the object not submerged in liquid. That is, the reservoir 3 provides more cleaning water to the top of the object being wiped by the cleaning component 2 in the backflow state. When the cleaning component 2 is pulled upward, the reservoir 3 flips clockwise to drain the liquid in its second reservoir 321, preventing the liquid remaining in the second reservoir 321 from flowing back to the cleaning component 2 in the final stage of cleaning, which would prevent it from being completely squeezed dry. The cleaning component 2 is repeatedly pulled up and down relative to the scraper part 11, and the cleaning component 2 completes the cleaning. The reset component 51 pushes the reservoir 3 to flip and reset.
