Description

Technical Field

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

[0002] Chinese patent CN210749071U discloses a "Water Control Mechanism for Mop Cleaning," which includes a water storage container, a thrust component, and a water valve. The water flow is controlled by manually operating the water valve. When cleaning the mop, the water valve is opened, and clean water flows out; after cleaning, the water valve is closed. The water storage container includes a large container and a small container, with the volume of the small container determining the quantitative control of the water used in a single cleaning cycle. This design of large and small containers increases the overall size of the cleaning device and makes it impossible to automatically stop injecting clean water into the cleaning chamber after a quantitative water injection. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a cleaning device that achieves a constant fluid medium volume for cleaning flat mops, resulting in stable cleaning effect and good water-saving effect.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a cleaning device, comprising:

[0005] The first container is used to store the fluid medium;

[0006] The second container, used for cleaning the flat mop, has a squeezing nozzle at its upper part with a squeezing component. The second container is connected to the first container through a liquid supply area, and at least a portion of the second container is located below the liquid supply area.

[0007] A first liquid storage area is formed between the bottom of the second container and the top of the liquid supply area, and a second liquid storage channel is formed between the top of the liquid supply area and the plane where the scraper is located.

[0008] The first container quantitatively supplies fluid medium that can fill the first storage area to the second container through the liquid supply area, and the height of the fluid medium in the first storage area is h1; when the flat mop is inserted into the second container, part of the fluid medium in the first storage area is transferred to the second storage channel, and the height of the fluid medium transferred from the first storage area to the second storage channel is h2.

[0009] During at least part of the cleaning process, the ratio of h1 to h2 remains constant as the total amount of fluid medium in the first container changes.

[0010] Furthermore, the height of the first liquid storage area is less than the height of the flat mop.

[0011] Furthermore, when the flat mop is inserted into the second container, the total height of the fluid medium in the first liquid storage area and the second liquid storage channel is less than the height of the flat mop.

[0012] Furthermore, if the height of the flat mop is H, then h1 / H is 1 / 4-1 / 2.

[0013] Furthermore, if the height of the flat mop is H, then (h1+h2) / H is 3 / 4-4 / 5.

[0014] Furthermore, the cavity above the fluid medium in the first container is in a sealed state. In the sealed state, the fluid medium in the first container can flow to the second container until the fluid medium in the second container submerges the supply area.

[0015] Furthermore, the volume of the first container is greater than or equal to twice the volume of the first liquid storage area.

[0016] Furthermore, the squeezing component includes a squeezing body that can abut against the flat mop, and a squeezing groove connected to the squeezing body. When the flat mop is pulled down to squeeze the squeezing component, the fluid medium discharged by the mutual squeezing enters the squeezing groove along the squeezing body, and the fluid medium in the squeezing groove flows back to the flat mop.

[0017] Furthermore, it also includes a third container, which is arranged around the first and second containers, and the flat mop pushes up and down relative to the squeezing member to transfer the fluid medium in the second container to the third container.

[0018] Furthermore, the liquid supply area extends horizontally, or the liquid supply area extends obliquely, or the top surface of the liquid supply area extends obliquely upward from the first container to the second container.

[0019] The beneficial effects of this utility model are: 1) The amount of fluid medium supplied from the first container to the second container is constant, the amount of fluid medium supplied from the first liquid storage area of ​​the second container to the second liquid storage channel is constant, the volume of fluid medium used for cleaning the flat mop is constant, and the cleaning effect of the flat mop remains stable each time; 2) The height of the first liquid storage area is less than the vertical height of the flat mop, so the fluid medium does not need to fill the second container when cleaning the mop, achieving a better water-saving effect; 3) When the flat mop is first inserted into the second container, the fluid medium in the second container will not submerge the entire vertical height of the flat mop, achieving a water-saving effect; 4) The cavity above the fluid medium in the first container is in a sealed state. Once external gas cannot enter the cavity, the fluid medium in the first container cannot be supplied to the second container, achieving the purpose of quantitatively supplying fluid medium from the first container to the second container, so that the amount of water used for cleaning the mop is constant each time, achieving a good effect. 5) After the target amount of water is injected into the second container, the first container automatically stops supplying fluid medium to the second container. No marking lines or subjective judgment by the user are required, making the quantitative measurement more accurate and the use more convenient; 6) The volume of the first container is at least twice the volume of the fluid medium quantitatively supplied to the second container, ensuring that one addition of water to the first container can complete at least two cleanings of the mop, resulting in a good mop cleaning effect while saving operation steps; 7) The fluid medium in the squeezing groove can flow back to the part of the flat mop that is not submerged by the fluid medium at the top. Even if the fluid medium does not submerge the entire height of the mop when the flat mop is first inserted into the second container, the mop can still be effectively cleaned, thus saving water; 8) The layout design of the first, second, and third containers makes the overall size of the cleaning device small and the structure stable; 9) The liquid supply area can be set in various forms to adapt to cleaning devices of different shapes.

Detailed Implementation

[0028] 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.

[0029] like Figures 1-5 As shown, a cleaning device includes a first container 1 for storing a fluid medium and a second container 2 for cleaning a flat mop 4. The first container 1 and the second container 2 are connected to the first container 1 through a liquid supply zone 3, and at least a portion of the second container 2 is located below the bottom of the liquid supply zone 3. A squeezing port 21 is provided on the upper part of the second container 2, and the squeezing port 21 has a squeezing member 22. The squeezing member 22 is located near the drain channel, which is used to discharge the fluid medium squeezed out by the flat mop 4 relative to the squeezing member 22. This is a structure in the prior art and will not be described in detail.

[0030] A first liquid storage area 231 is formed between the bottom of the second container 2 and the top of the liquid supply area 3, and a second liquid storage channel 232 is formed between the top plane of the liquid supply area 3 and the plane of the scraper 22. It should be noted that the liquid supply area 3 refers to the area through which the fluid medium can pass, not a specific component, and its specific shape is not limited. The plane of the scraper 22 is also a general term; it can be the plane of the lowest point of the scraper 22, the plane of the highest point of the scraper 22, the plane of the center of the scraper 22, or the entire thickness of the scraper 22 can be abstracted into a plane, without being a specific limitation. In this embodiment, as... Figure 2 As shown, the plane where the top of the scraper 22 is located in the horizontal state is the plane where the scraper 22 is located.

[0031] The first container 1 supplies a quantitative amount of fluid medium, sufficient to fill the first storage zone 231, to the second container 2 through the supply zone 3. The height of the fluid medium within the first storage zone 231 is defined as h1. Figure 3 As shown.

[0032] When the flat mop 4 is inserted into the second container 2, a portion of the fluid medium in the first storage area 231 is transferred to the second storage channel 232. The height of the fluid medium transferred from the first storage area 231 to the second storage channel 232 is defined as h2. Figure 4 As shown.

[0033] During at least part of the cleaning process, the ratio of h1 to h2 remains constant as the total volume of fluid medium in the first container 1 changes. Specifically, when the volume of fluid medium in the first container 1 is greater than the volume of fluid medium in the first storage zone 231, the ratio of h1 to h2 remains constant as the total volume of fluid medium in the first container 1 decreases during the cleaning process.

[0034] It should be noted that the ratio of h1 to h2 remains constant here. This includes the case where, when the flat mop 4 is inserted into the second container 2, the fluid medium transferred from the first liquid storage area 231 to the second liquid storage channel 232 is less than the upper squeezing port 21 of the second container 2. It also includes the case where, when the flat mop 4 is inserted into the second container 2, the fluid medium transferred from the first liquid storage area 231 to the second liquid storage channel 232 exceeds the upper squeezing port 21 of the second container 2 and is discharged outward.

[0035] The height of the first liquid storage area 231 is less than the height of the flat mop 4. Therefore, during the cleaning process of the flat mop 4, the amount of fluid medium in the first liquid storage area 231 is relatively small, and the amount of fluid medium consumed in cleaning the flat mop 4 is small. When the flat mop 4 is inserted into the second container 2, the total height of the fluid medium in the first liquid storage area 231 and the second liquid storage channel 232 is less than the vertical height of the flat mop 4. In other words, when the flat mop 4 is first inserted into the second container 2 for cleaning, the fluid medium in the second container 2 does not cover the top of the flat mop 4, and the fluid medium will not overflow from the second container 2. Only during the up-and-down pulling and pushing process of the flat mop 4 will the fluid medium on the wiping object be discharged from the scraping port 21.

[0036] Specifically, defining the vertical height of the flat mop 4 as H, then h1 / H is 1 / 4-1 / 2, meaning the ratio of the height of the fluid medium in the first liquid storage area 231 to the vertical height of the flat mop 4 will not exceed 1 / 2. With the fluid medium of the aforementioned volume, the flat mop 4 can effectively clean completely, resulting in excellent water conservation. Furthermore, (h1+h2) / H is 3 / 4-4 / 5, meaning that when the flat mop 4 is vertically inserted into the second container 2, the ratio of the height of the fluid medium in the second container 2 to the vertical height of the flat mop 4 will not exceed 1 / 2. This means that when the flat mop 4 is initially inserted into the second container 2 for cleaning, the fluid medium in the second container 2 will not overflow.

[0037] In order to ensure that the flat mop 4 is effectively cleaned without submerging the entire vertical height of the fluid medium in the second container 2, such as... Figure 6 , Figure 7 As shown, the scraping component 22 includes a scraping body 221 that can abut against the wiping material on the flat mop 4, and a scraping groove 222 connected to the scraping body 221. In this embodiment, the scraping body 221 and the scraping groove 222 are integrally connected. Specifically, the scraping groove 222 bends and extends towards one side wall of the flat mop 4 to form the scraping body 221. Of course, in other embodiments, the scraping body 221 may also be indirectly connected to the scraping groove 222, that is, another connecting component is provided between the two, and there is no specific limitation. Alternatively, in other embodiments, the scraping body 221 and the scraping groove 222 are not integrally connected, but are linked together, and there is no specific limitation.

[0038] In this embodiment, the scraping groove 222 is an open-topped groove with a roughly V-shaped cross-section. It is flipped and connected to the scraping port 21 of the second container 2. Specifically, after both ends of the scraping groove 222 are closed, it is flipped and connected to the side wall of the second container 2 via a pivot. One side of the open top of the scraping groove 222 is integrally connected to the scraping body 221, and the other side of the open top forms a water-blocking surface higher than the plane of the scraping body 221. Of course, in other embodiments, the scraping member 22 can also be flipped and connected to other parts.

[0039] When the flat mop 4 is pulled downwards within the second container 2, the fluid medium for wiping the material on the flat mop 4 is squeezed by the squeezing body 221. At this time, the squeezing groove 222 rotates with the squeezing body 221, and the fluid medium flows into the squeezing groove 222 along the squeezing body 221. Simultaneously, the fluid medium accumulated in the squeezing groove 222 flows back towards the material being wiped, replenishing and increasing the fluid medium flowing to the material, thus achieving the purpose of wiping the material with the entire flat mop 4, while also saving water. Of course, when the flat mop 4 is pulled downwards, the fluid medium overflowing the squeezing groove 222 can also be directly discharged through the drainage channel. The above description of the function of the squeezing groove 222 in different usage states is not intended to limit it.

[0040] When the first container 1 contains a fluid medium, the cavity above the fluid medium in the first container 1 is at least in a closed state. In the closed state, the fluid medium in the first container 1 can flow to the second container 2 until the fluid medium in the second container 2 submerges the liquid supply area 3. At this time, the fluid medium in the first container 1 will no longer be supplied to the second container 2.

[0041] Specifically, the first container 1 is relatively closed, and can only be connected to the outside at the liquid supply area 3. When the first container 1 and the second container 2 are connected, that is, when the fluid medium in the second container 2 has not yet submerged the top of the liquid supply area 3, outside air can enter the cavity above the fluid medium in the first container 1 through the liquid supply area 3. Under the gas pressure and gravity of the fluid medium in the cavity, the fluid medium in the first container 1 can flow to the second container 2. When the liquid supply area 3 is blocked by the fluid medium (here, the physical isolation between the first container 1 and the second container 2 is not considered, only the liquid seal is involved), that is, when the fluid medium in the second container 2 just submerges the top of the liquid supply area 3, outside air can enter the cavity above the fluid medium in the first container 1. Air from the outside will not enter the cavity above the fluid medium in the first container 1 through the liquid supply area 3. At this time, the cavity above the fluid medium in the first container 1 is in a closed state, that is, no outside air is replenished into the cavity. The outside atmospheric pressure is greater than the gas pressure inside the cavity, and the cavity forms a negative pressure. The air pressure inside the cavity is insufficient to push the fluid medium in the first container 1 to continue to be transported to the second container 2. In other words, the gravity of the fluid medium cannot overcome the pressure difference between the outside air pressure and the cavity, so that the fluid medium in the first container 1 will not continue to flow to the second container 2. At this time, the fluid medium entering the second container 2 is a quantitative fluid medium, which achieves the purpose of quantitatively transporting the fluid medium from the first container 1 to the second container 2.

[0042] It should be noted that "the fluid medium submerges the supply zone 3," or "covers or blocks the supply zone 3," means that when the supply zone 3 extends horizontally, it is completely filled with fluid medium in both its radial and axial directions. Alternatively, "the fluid medium covers the supply zone 3" means that the fluid medium covers the lowest horizontal point at the top of the supply zone 3; in this case, it does not necessarily mean that the entire radial direction of the supply zone 3 is filled with fluid medium. Specifically, if the radial width of the supply zone 3 on the side of the first container 1 is smaller than its radial width on the side of the second container 2, meaning the top surface of the supply zone 3 extends upwards at an angle from the first container 1 to the second container 2, the supply zone 3 is blocked when the fluid medium covers the side with the smaller radial width. Alternatively, if the supply zone 3 is angled, the plane containing the lowest horizontal point at the top of the supply zone 3 is blocked when the fluid medium covers this lowest plane. In all these scenarios, there is no space within the supply zone 3 where air can flow into the cavity above the fluid medium in the first container 1. There are no restrictions on the specific shape of the liquid supply area 3, nor on the height and size of the two sides of the liquid supply area 3, as long as the liquid supply area 3 is sealed by the fluid medium and air cannot flow from the liquid supply area 3 into the cavity.

[0043] The determination of the volume of the aforementioned quantitative fluid medium, that is, the determination of the volume of the first storage zone 231, is determined by the volume space defined by the lowest horizontal height of the top of the supply zone 3 and the bottom of the second container 2. In this embodiment, part of the second container 2 is located below the height of the supply zone 3, and part of the second container 2 is located above the height of the supply zone 3. Of course, in other embodiments, most of the second container 2 may be located below the height of the supply zone 3, as long as the fluid in the second container 2 can submerge the supply zone 3; there are no specific limitations.

[0044] Let V1 be the volume of the first container 1 and V2 be the volume of the first liquid storage area 231. Then V1 ≥ 2V2. This means that when the first container 1 is full of fluid medium, it can deliver a fixed amount of fluid medium to the first liquid storage area 231 at least twice, ensuring that the flat mop 4 can be cleaned effectively and avoiding the inconvenience of repeated water addition. Of course, the volume of the first container 1 can be much larger than twice V2 to reduce the number of water addition steps.

[0045] A transfer pipe 31 and a connecting pipe 32 are provided between the first container 1 and the second container 2. These two pipes, after being sealed and inserted together, form a liquid supply area 3. Specifically, the transfer pipe 31 protrudes from the outer wall of the second container 2, while the connecting pipe 32 is recessed from the outer wall of the first container 1. The outer diameter of the transfer pipe 31 matches the inner diameter of the connecting pipe 32, so that the outer wall of the transfer pipe 31 is fitted with a sealing ring and then sealed and inserted into the connecting pipe 32. Of course, in other embodiments, the connecting pipe can also be formed by the outer wall of the first container 1 protruding and the outer wall of the second container 2 recessing, or both the outer walls of the first container 1 and the second container 2 protruding; no specific limitation is imposed. In other embodiments, the liquid supply area 3 can also be a narrow flow gap; its specific structure is not limited, as long as it enables communication between the first container 1 and the second container 2.

[0046] The cleaning device also includes a third container 5 for receiving the fluid medium discharged from the squeezing port 21 of the second container 2. Specifically, the flat mop 4 pulls and pushes relative to the squeezing member 22, transferring the fluid medium adsorbed on the wiping material to the third container 5 through the drainage channel. The third container 5 is arranged around the first container 1 and the second container 2. Specifically, in this embodiment, the first container 1 and the second container 2 are entirely located inside the third container 5, and the first container 1 and the second container 2 are arranged side-by-side. The top of the first container 1 and the top of the second container 2 are approximately at the same height, and the bottom of the second container 2 is below the bottom of the first container 1. In this embodiment, the second container 2 extends downward to the bottom of the third container 5. Of course, in other embodiments, parts of the first container 1 and the second container 2 may be located above the top surface of the third container 5, and parts may be located outside the third container 5, with a certain distance between the bottom of the second container 2 and the inner bottom surface of the third container 5; the first container 1 and the second container 2 may be arranged vertically, with most of the second container 2 located below the first container 1; or the first container 1, the second container 2, and the third container 5 may be arranged side-by-side. No specific limitations are imposed.

[0047] 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.
