[0002] Chinese patent CN210749071U discloses a water control mechanism for mop cleaning, which comprises a water storage container, a thrust piece and a water valve. The water flow is controlled by manually operating the switch of 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 comprises a large container and a small container. The quantitative control of the water quantity for single cleaning is determined by the volume of the small container. The design of the large and small containers increases the overall volume of the cleaning device, and the water storage container cannot automatically stop injecting clean water into the cleaning cavity after quantitative water injection. SUMMARY

[0003] In order to overcome the shortcomings of the prior art, the utility model provides a flat mop cleaning device, which realizes quantitative delivery of fluid medium for cleaning the mop, and can automatically stop inputting after completing quantitative delivery, is convenient to use, and has good water saving effect.

[0004] The utility model solves the technical problems by adopting the following technical scheme: a flat mop cleaning device, comprising:

[0005] A first container is used for storing fluid medium and forming a pressure chamber in the area above the fluid medium;

[0006] A second container is used for cleaning and wringing the mop;

[0007] A third container is used for receiving the fluid medium discharged from the upper part of the second container;

[0008] A communication channel is located between the first container and the second container;

[0009] At least part of the second container is located below the height of the communication channel. A transfer channel is provided between the second container and the third container, and the fluid medium discharged from the upper part of the second container enters the third container through the transfer channel. The transfer channel is provided with a squeezing and scraping unit. At least part of the communication channel is located below the squeezing and scraping unit.

[0010] When the first container and the second container are in a communication state, external gas enters the pressure chamber through the communication channel, and the fluid medium of the first container flows to the second container until the communication channel is liquid sealed by the fluid medium to prevent gas from entering the pressure chamber.

[0011] Further, the top of the first container is formed with a liquid inlet, which is blocked by a sealing plug to form a pressure chamber in the area above the fluid medium in the first container.

[0012] Further, when the communication channel is blocked by the fluid medium, the fluid medium in the first container stops flowing to the second container, and the fluid medium entering the second container is a quantified fluid medium.

[0013] Further, the volume of the quantified fluid medium entering the second container is the volume defined by the lowest point of the top of the communication channel and the bottom of the second container.

[0014] Further, the volume of the first container is V1, and the volume of the fluid medium in the second container when the communication channel is blocked by the fluid medium is V2, then V1≥2V2.

[0015] Further, when the mop is vertically inserted into the quantified fluid medium in the second container, the liquid surface of the fluid medium in the second container is lower than the top end of the mop.

[0016] Further, the second container includes a chamber one for vertically accommodating the mop rod, and a chamber two for vertically accommodating the mop body, the chamber one and the chamber two are in communication, the bottom of the chamber two is below the bottom of the chamber one, and the communication channel is arranged on the side wall of the chamber two.

[0017] Further, the third container is arranged around the first container and the second container, the second container extends downward to the bottom of the third container, and a support table is arranged between the third container and the first container, the support table is connected to the bottom of the first container, or the support table is connected to the third container, or the support table is independently arranged.

[0018] Further, the bottom of the first container is protruded to form a limiting part one, the second container forms a limiting part two, and the support table is limitedly connected with the limiting part one and the limiting part two respectively.

[0019] Further, the first container and the second container have a transition pipeline and a docking pipeline, and the transition pipeline and the docking pipeline form the communication channel after being sealed and sleeved.

[0020] Further, the squeezing and scraping unit includes a scraper part which can be abutted with the mop, and a water storage tank which is reversely connected, at least part of the water storage tank is in communication with the scraper part, when the mop is pulled downward to squeeze the scraper part, the two are squeezed to discharge the fluid medium which enters the water storage tank along the scraper part, and the fluid medium in the water storage tank flows back to the mop.

[0021] Further, it further includes a blocking piece for communication or isolation between the first container and the second container.

[0022] Further, the blocking piece at least includes a blocking part and a pushing part which is extended from the self-cleaning device, an external force is applied to the pushing part to drive the blocking piece to move, and the blocking part can block or open the communication channel.

[0023] Furthermore, if the maximum width of the connecting channel is L1 and the maximum width of the squeezing unit is L2, then L2 > L1.

[0024] The beneficial effects of this utility model are: 1) A pressure chamber is set in the first container. Once external gas cannot enter the pressure chamber, the fluid medium in the first container cannot be delivered to the second container, thus achieving the purpose of quantitatively delivering the fluid medium from the first container to the second container, making the water volume constant each time the mop is washed, and achieving a good water-saving effect; 2) After the target amount of water is injected into the second container, the first container automatically stops delivering the fluid medium to the second container, eliminating the need for setting a marking line or subjective judgment by the user, making the quantitative delivery more accurate and the use more convenient; 3) The setting of the liquid inlet facilitates the delivery of the fluid medium to the first container, and the sealing plug occupies the liquid inlet, which also facilitates the effective formation of the pressure chamber; 4) The quantitative delivery of the fluid medium from the first container to the second container is limited by the height of the lowest point of the connecting channel and the bottom of the second container, so that the flow rate during mop washing is controlled. 5) The fluid medium does not need to fill the second container, achieving better water-saving effect; 6) The barrier separates the first and second containers, so that the mop will not contaminate the clean water in the first container when it is cleaned in the second container; 7) The layout design of the first, second and third containers makes the overall size of the cleaning device small and the structure stable; 8) The fluid medium in the water tank of the squeezing unit can flow back to the part of the flat mop that is not submerged by the fluid medium. Even if the fluid medium does not submerge the entire height of the mop when it is first inserted into the second container, the mop can still be effectively cleaned, which saves water; 9) The volume of the first container is at least twice the volume of the fluid medium quantitatively delivered to the second container, ensuring that the first container can complete at least two cleanings of the mop with one filling of water, which not only cleans the mop well but also saves operating steps.

DETAILED DESCRIPTION

[0042] In order to make the person skilled in the art better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present application.

[0043] As shown in the drawings, Figures 1-5 A flat mop cleaning device, comprising a first container 1 for storing fluid medium, a second container 2 for cleaning and squeezing the mop 8, a third container 3 for receiving the fluid medium discharged from the upper part of the second container 2, and a communication channel 4 between the first container 1 and the second container 2, the communication channel 4 is used to connect or block the first container 1 and the second container 2, when the communication channel 4 connects the first container 1 and the second container 2, the communication channel 4 is used to transport the fluid in the first container 1 to the second container 2, at least part of the second container 2 is below the height of the bottom horizontal height of the communication channel 4.

[0044] In the present embodiment, the fluid medium is water, of course, in other embodiments, it can also be other cleaning liquid, etc., and the specific limitation is not limited. In the present embodiment, the mop 8 is a flat mop, of course, in other embodiments, it can also be other styles of existing mop, and the specific limitation is not limited.

[0045] When the first container 1 contains a fluid medium, a pressure chamber 11 is formed in the area above the fluid medium in the first container 1. When the first container 1 and the second container 2 are in a connected state, external gas enters the pressure chamber 11 through the connecting channel 4. The fluid medium in the first container 1 flows to the second container 2 until the connecting channel 4 is sealed 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), thereby preventing gas from entering the pressure chamber 11. The connecting channel 4 is blocked from the first container 1 and the second container 2 due to the liquid seal. That is, at this time, the fluid medium in the first container 1 stops flowing to the second container 2. The fluid medium entering the second container 2 is a quantitative fluid medium, thus achieving the purpose of quantitatively delivering the fluid medium from the first container 1 to the second container 2.

[0046] Specifically, the first container 1 is relatively closed, and can only be connected to the outside world through the connecting channel 4. 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 blocked the connecting channel 4, outside air can enter the pressure chamber 11 above the fluid medium in the first container 1 through the connecting channel 4. Under the action of gas pressure and gravity of the fluid medium in the pressure chamber 11, the fluid medium in the first container 1 can flow to the second container 2. When the connecting channel 4 is blocked by the fluid medium, that is, when the fluid medium in the second container 2 just covers the connecting channel 4, such as Figure 10 As shown, outside air will not enter the pressure chamber 11 through the connecting channel 4. At this time, the pressure chamber 11 in the first container 1 is in a closed state, that is, no outside air is replenished into the pressure chamber 11. The outside atmospheric pressure is greater than the gas pressure inside the pressure chamber 11, and the pressure chamber 11 forms a negative pressure. The air pressure inside the pressure chamber 11 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 pressure chamber 11, so that the fluid medium in the first container 1 stops flowing to the second container 2. At this time, the fluid medium entering the second container 2 is a quantitative fluid medium, which realizes the purpose of quantitatively transporting the fluid medium from the first container 1 to the second container 2.

[0047] Specifically, when the mop 8 is vertically inserted into the metered fluid medium in the second container 2, the liquid level of the fluid medium in the second container 2 is lower than the top of the mop 8, that is, the metered fluid medium will not completely submerge the mop 8 and the wiping material, thereby achieving the purpose of saving water.

[0048] The first container 1 is relatively closed, which can be that the first container 1 has only one opening in the region where the communication passage 4 is located; or the first container 1 can be provided with a liquid inlet 13 at the top of the first container 1, which facilitates the pouring of the fluid medium into the first container 1. Once the pouring of the fluid medium into the first container 1 is completed, the liquid inlet 13 is blocked by a sealing plug 12, so that the pressure chamber 11 above the fluid medium in the first container 1 is in a closed state.

[0049] It should be noted that, as shown in Figure 9 , the fluid medium submerges, or overflows, or blocks the communication passage 4, which means that the entire radial and axial directions of the communication passage 4 are filled with the fluid medium; or, as shown in Figure 10 , the fluid medium overflows the communication passage 4, which means that the fluid medium overflows the lowest horizontal height of the top of the communication passage 4, and at this time, the entire radial direction of the communication passage 4 is not necessarily filled with the fluid medium. Specifically, as shown in Figure 7 , at this time, the radial width of the communication passage 4 located on one side of the first container 1 is smaller than the radial width of the communication passage 4 located on the other side of the first container 1. When the fluid medium overflows the side with smaller radial width, the communication passage 4 is blocked, that is, when the fluid medium overflows the plane L1, the communication passage 4 is blocked; as shown in Figure 8 , at this time, the communication passage 4 is inclined, and at this time, the lowest horizontal height of the top of the communication passage 4 is located on the plane L2. When the fluid medium overflows this L2 plane, the communication passage 4 is blocked. The above various cases make the communication passage 4 not have air that can flow into the pressure chamber 11 above the fluid medium in the first container 1. The specific shape of the communication passage 4 is not limited, and the height of the two sides of the communication passage 4 is also not limited, as long as the communication passage 4 is liquid sealed by the fluid medium, and air cannot flow into the pressure chamber 11 from the communication passage 4.

[0050] The determination of the volume of the quantified fluid medium entering the second container 2 is determined by the volume space defined by the lowest horizontal height of the top of the communication passage 4 and the bottom of the second container 2, that is, as shown in Figure 11 , the volume of the quantified fluid medium entering the second container 2 is determined by the height space volume indicated by H, and at this time, the blocking piece 5 is provided, and the width of the blocking piece 5 is limited by the blocking piece 5 and the side wall of the second container 2. In this embodiment, part of the second container 2 is located below the height of the communication passage 4, and part of the second container 2 is located above the height of the communication passage 4. Of course, in other embodiments, most of the second container 2 can be located below the height of the communication passage 4, as long as the fluid in the second container 2 can overflow the communication passage 4, and the specific implementation is not limited.

[0051] Let the volume of the first container 1 be V1. When the fluid medium in the second container 2 is above the connecting channel 4, the volume of the fluid medium in the second container 2 is V2. Therefore, 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 second container 2 at least twice, ensuring the mop 8 is cleaned effectively and avoiding the inconvenience of repeated water addition. Alternatively, the volume of the first container 1 could be much larger than twice V2 to reduce the number of water addition steps.

[0052] like Figure 2 , Figure 4 As shown, a transfer pipe 41 and a connecting pipe 42 are provided between the first container 1 and the second container 2. These two pipes, after being sealed together internally and externally, form a connecting channel 4. Specifically, the transfer pipe 41 protrudes from the outer wall of the second container 2, while the connecting pipe 42 is recessed from the outer wall of the first container 1. The outer diameter of the transfer pipe 41 matches the inner diameter of the connecting pipe 42, so that the outer wall of the transfer pipe 41, after being fitted with a sealing ring, is sealed and inserted into the connecting pipe 42. Of course, in other embodiments, the connecting pipe may also protrude from the outer wall of the first container 1, and the connecting pipe 42 may be recessed from the outer wall of the second container 2, or both may protrude from the outer wall of the first container 1 and the second container 2; no specific limitation is imposed.

[0053] The flat mop cleaning device also includes a barrier 5, which serves to connect or isolate the first container 1 and the second container 2. Figures 13-14 As shown, the barrier 5 includes at least a blocking part 51, a toggle part 52 extending from the top of the self-cleaning device, and a support part 53 disposed near the blocking part 51. When an external force is applied to the toggle part 52 to drive the barrier 5 to move, the blocking part 51 can close or open the connecting channel 4. In this embodiment, the toggle part 52 is shaped like a "7".

[0054] In use, the blocking part 51 of the barrier 5 is moved down into the connecting channel 4, at which point the connecting channel 4 is closed, and the first container 1 and the second container 2 are isolated from each other. Even if the fluid medium in the second container 2 is reduced due to being absorbed by the mop 8, air will not enter the pressure chamber 11 of the first container 1 through the connecting channel 4. Once the blocking part 51 moves up, opening the connecting channel 4, the first container 1 and the second container 2 are connected to each other. If the fluid medium in the second container 2 is reduced due to being absorbed by the mop 8, the fluid medium in the first container 1 will automatically be transported to the second container 2 until the fluid medium in the second container 2 blocks the connecting channel 4 again.

[0055] Of course, the barrier 5 can be omitted. In this case, the mop absorbs the fluid medium in the second container 2, and the fluid medium in the first container 1 is immediately and automatically transported to the second container 2.

[0056] The barrier 5 can avoid the fluid medium in the second container 2 from flowing to the first container 1 after the mop 8 is cleaned, resulting in incomplete cleaning of the mop 8. In order to ensure that the barrier 5 is in a state of closing the communication passage 4 and isolating the first container 1 and the second container 2 when the mop 8 is inserted into the second container 2, a supporting portion 53 is arranged on the barrier 5, so that when the mop 8 is inserted into the second container 2, the mop 8 can be lowered against the supporting portion 53, thereby driving the barrier 5 to move, that is, ensuring that the barrier 5 can be lowered to close the communication passage 4. Of course, when the mop 8 is moved upward along the second container 2, it will not interfere with the supporting portion 53, and the barrier 5 is in a state of closing the communication passage 4.

[0057] In order to press the barrier 5 towards the direction of the communication passage 4 and ensure that the communication passage 4 is effectively closed, as shown in Figure 12 a lower limiting piece 21 is arranged in the second container 2, and the distance between the lower limiting piece 21 and the side wall of the second container 2 is slightly smaller than or equal to the thickness of the blocking portion 51, so that once the blocking portion 51 is inserted between the side wall of the second container 2 and the lower limiting piece 21, it will not easily come off, and the fluid medium is also relatively difficult to flow between the first container 1 and the second container 2.

[0058] In order to keep the barrier 5 in an open state of the communication passage 4 or keep the barrier 5 in a closed state of the communication passage 4, a locking structure 6 is arranged between the barrier 5 and the second container 2. As shown in Figures 15-16 the locking structure 6 includes a locking protrusion 61 and a locking sliding groove 62, and the locking sliding groove 62 includes a first locking groove 621, a transition groove 622 and a second locking groove 623 which are communicated with each other. The first locking groove 621 and the transition groove 622 have a first stop protrusion 624 therebetween, and the transition groove 622 and the second locking groove 623 have a second stop protrusion 625 therebetween. The first stop protrusion 624 and the second stop protrusion 625 are protrusions extending to the center from the inner wall of the locking sliding groove 62, which reduces the width of the locking sliding groove 62.

[0059] In order to ensure that the locking protrusion 61 can be smoothly switched between the first locking groove 621 and the transition groove 622, and in order to ensure that the locking protrusion 61 can be smoothly switched between the second locking groove 623 and the transition groove 622, a resilient hollow groove 63 can be arranged beside the first stop protrusion 624, or a resilient hollow groove 63 can be arranged beside the second stop protrusion 625. Thus, the width of the locking sliding groove 62 is easy to elastically change at the position close to the resilient hollow groove 63, in other words, the locking sliding groove 62 is easy to be squeezed and opened and timely reset, and the operation of switching the position of the locking protrusion 61 between the first locking groove 621 and the transition groove 622 is more labor-saving.

[0060] In the present embodiment, the locking protrusion 61 is arranged on the blocking piece 5, and the locking sliding groove 62 is arranged on the positioning seat 24 which is detachably connected to the second container 2. Of course, the positions of the locking protrusion 61 and the locking sliding groove 62 can also be interchanged, i.e. the locking protrusion 61 is arranged on the positioning seat 24 or directly on the second container 2, and the locking sliding groove 62 is arranged on the blocking piece 5.

[0061] For the detachable structure of the positioning seat 24 and the second container 2, as shown in the figure, a clamping portion 23 is formed on the second container 2 near the top opening, a buckling portion 241 is formed on the positioning seat 24, and the buckling portion 241 is arranged on a spring sheet 242, so that the clamping portion 23 and the buckling portion 241 are buckled and fitted, realizing the detachable installation of the positioning seat 24 and the second container 2. Figure 12

[0062] In use, when it is needed to keep the blocking portion 51 in the state of closing the communication passage 4, an external force is applied to press the pushing portion 52 downward, so that the locking protrusion 61 moves along the locking sliding groove 62 to the second locking groove 623 and is limited in the second locking groove 623 by the second stop protrusion 625; when it is needed to switch the blocking portion 51 to the state of opening the communication passage 4, an external force is applied to pull the pushing portion 52 upward, so that the locking protrusion 61 passes the second stop protrusion 625, passes the first stop protrusion 624 and enters the first locking groove 621, and is limited in the first locking groove 621 by the first stop protrusion 623.

[0063] In order to cooperate with the blocking portion 51 to keep the blocking piece 5 in the state of effectively closing the communication passage 4, an upper limiting piece 22 is arranged at the top opening of the second container 2, which extrudes the pushing portion 52 of the blocking piece 5 to the direction of the locking structure 6. Of course, the above-mentioned upper limiting piece 22 also helps to keep the locking protrusion 61 in the locking sliding groove 62, avoiding its transverse disengagement.

[0064] Regarding the layout of the first container 1, the second container 2 and the third container 3, the third container 3 is arranged around the first container 1 and the second container 2. Specifically, in the present embodiment, the first container 1 and the second container 2 are located inside the third container 3 as a whole, and are arranged side by side, the top of the first container 1 and the top of the second container 2 are located at about the same height, and the bottom of the second container 2 is below the bottom of the first container 1. In the present embodiment, the second container 2 extends downward to the bottom of the third container 3. Of course, in other embodiments, part of the first container 1 and the second container 2 can be above the height of the top surface of the third container 3, part of which is located outside the third container 3, and there is a certain distance between the bottom of the second container 2 and the inner bottom surface of the third container 3; it can also be that the first container 1 and the second container 2 are arranged one above the other, i.e. most of the second container 2 is located below the first container 1; it can also be that the first container 1, the second container 2 and the third container 3 are arranged side by side, and the specific arrangement is not limited.​

[0065] The mop 8 comprises a flat mop body and a mop rod rotatably connected to the mop body, the mop rod can be rotated to be attached to the side of the mop body, so that both are in vertical state. More specifically, the second container 2 comprises a chamber one 281 for vertically accommodating the mop rod, and a chamber two 282 for vertically accommodating the mop body, the chamber one 281 and the chamber two 282 are communicated, the inside of the chamber one 281 is adapted to the shape of the mop rod, the inside of the chamber two 282 is adapted to the shape of the mop body, the bottom of the chamber two 282 is below the bottom of the chamber one 281, and the width of the bottom of the chamber two 282 is equivalent to the width of the mop body, so as to reduce the volume of the second container 2, the bottom of the chamber two 282 is close to the bottom of the third container 3, the bottom of the chamber one 281 is below the bottom of the first container 1, the above-mentioned communication channel 4 is arranged on the side wall of the chamber two 282, specifically, the 2 outer wall of the chamber one 281 protrudes to form an adapter pipe 41.

[0066] Since the bottom of the second container 2 is below the bottom of the first container 1, in order to realize the stable support of the first container 1, a support table 7 is arranged between the third container 3 and the first container 1, the support table 7 is connected to the bottom of the first container 1, and extends downward until abutting against the inner bottom of the third container 3; or, the support table 7 is connected to the third container 3, and extends upward until abutting against the bottom of the first container 1; or, the support table 7 is independently arranged, and is neither connected to the bottom of the first container 1 nor connected to the third container 3, but is an independent component arranged between the first container 1 and the third container 3; also, the support table 7 can be connected to the second container 2, and extends to the bottom of the first container 1, and part of the support table 7 continues to extend to the bottom of the third container 3, of course, the above-mentioned support table 7 can also be an independent component, and does not necessarily need to be connected to the second container 2.

[0067] In order to increase the stability of the whole structure, the first container 1 forms a limiting part one 14, the second container 2 forms a limiting part two 25, and the support table 7 is in limiting connection with the limiting part one 14 and the limiting part two 25 respectively. Specifically, the limiting part one 14 extends downward from the bottom of the first container 1, the limiting part two 25 extends downward from the bottom of the adapter pipeline 41, the limiting part one 14 and the limiting part two 25 extend towards the same direction and are connected with the support table 7, and the support table 7 supports the first container 1 and the second container 2 at the same time, thereby forming a stable connection and support among the first container 1, the second container 2 and the support table 7. The second container 2 is provided with a squeezing and scraping unit 27 and a transfer channel 26, the transfer channel 26 is located between the second container 2 and the third container 3, and the fluid medium discharged from the upper part of the second container 2 enters the third container 3 through the transfer channel 26, and the third container 3 is used as a waste water cavity. The squeezing and scraping unit 27 is arranged near the transfer channel 26, and at least part of the communication channel 4 is located below the squeezing and scraping unit 27. In this embodiment, the whole communication channel 4 is located far below the squeezing and scraping unit 27.
