[0041] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0042] The following is for reference. Figures 1-5 The cleaning device described according to an embodiment of the present utility model can realize the automatic proportioning of cleaning liquid and clean water, and can also simplify the proportioning mechanism 100.

[0043] Combination Figures 1-5 As shown, the cleaning equipment according to the first aspect of this utility model includes a cleaning liquid tank, a clean water tank, and a mixing mechanism 100. The cleaning equipment can be a floor scrubber, a carpet / fabric cleaner, a sweeper, or similar equipment. The cleaning liquid tank stores the cleaning liquid, the clean water tank stores clean water, and the mixing mechanism 100 mixes the cleaning liquid and clean water in a predetermined ratio to ensure the correct concentration of the cleaning liquid, thereby improving the cleaning effect.

[0044] Specifically, the mixing mechanism 100 includes an inlet 11, an outlet 12, and a liquid passage 21. The inlet 11 is connected to the cleaning liquid tank, and the outlet 12 is connected to the clean water tank so that the cleaning liquid and clean water form a mixture. The liquid passage 21 connects the inlet 11 and the outlet 12.

[0045] Specifically, the inlet 11 and outlet 12 of the mixing mechanism 100 are connected to the cleaning solution tank and the clean water tank, respectively. The cleaning solution in the cleaning solution tank can flow into the mixing mechanism 100 through the inlet 11. After flowing out of the outlet 12, the cleaning solution in the cleaning solution tank can mix with the clean water flowing into the mixing mechanism 100 from the clean water tank to form a mixed solution. This facilitates the mixing effect of the cleaning solution and clean water in the mixing mechanism 100.

[0046] Furthermore, the cleaning solution and water in the mixing mechanism 100 can only communicate with each other through the liquid passage 21. Since the flow cross-sectional area of ​​the liquid passage 21 and the flow cross-sectional area of ​​the outlet 12 are fixed, the mixing ratio of the cleaning solution and water is relatively fixed. This ensures that the cleaning solution and water can be mixed according to the preset ratio, thereby ensuring that the cleaning solution reaches the correct concentration each time it is used, improving the cleaning effect. Moreover, using the correct ratio of cleaning solution can avoid unnecessary waste, remove dirt more effectively, reduce the need for repeated cleaning, and improve cleaning efficiency.

[0047] Furthermore, since the liquid passage 21 is located on the proportioning mechanism 100, different proportions of cleaning liquid and clean water can be achieved by replacing the proportioning mechanism 100 with different sizes or numbers of liquid passage 21 (for example, increasing the number of liquid passage 21 on the proportioning mechanism 100 or widening the width of the liquid passage 21), thereby improving the efficiency of changing the proportion of cleaning liquid and clean water.

[0048] Therefore, by setting up this cleaning equipment, the automatic mixing ratio of cleaning liquid and clean water can be realized, thereby improving the cleaning effect. It can also simplify the mixing mechanism 100 and improve the convenience and flexibility of changing the mixing ratio.

[0049] According to some optional embodiments of the present invention, combined with Figures 1-3 As shown, the proportioning mechanism 100 includes a housing 1 and a sealing plug 2. The housing 1 has a liquid inlet 11 and a liquid outlet 12. The sealing plug 2 is disposed inside the housing 1 and is located between the liquid inlet 11 and the liquid outlet 12. The sealing plug 2 is provided with a liquid passage 21 that connects the liquid inlet 11 and the liquid outlet 12.

[0050] Specifically, the housing 1 forms the main external structural outline of the mixing mechanism 100, which can protect the related internal structures. The inlet 11 and outlet 12 on the housing 1 are connected to the cleaning liquid tank and the clean water tank, respectively. The cleaning liquid in the cleaning liquid tank can flow into the housing 1 through the inlet 11. Since the outlet 12 on the housing 1 is connected to the clean water tank, the cleaning liquid in the housing 1 can flow further to the outlet 12 and mix with the clean water flowing into the mixing mechanism 100 from the clean water tank, so that the cleaning liquid and clean water in the mixing mechanism 100 can be mixed smoothly. The sealing plug 2 is sealed inside the housing 1, which helps to prevent the cleaning liquid and clean water in the housing 1 from leaking accidentally, thereby ensuring the sealing of the mixing mechanism 100.

[0051] Furthermore, the sealing plug 2 is located between the liquid inlet 11 and the liquid outlet 12. The cleaning liquid and clean water entering the housing 1 can only communicate with each other through the liquid passage 21 on the sealing plug 2. Since the flow cross-sectional area of ​​the liquid passage 21 and the flow cross-sectional area of ​​the liquid outlet 12 are fixed, the mixing ratio of the cleaning liquid and clean water is relatively fixed. This ensures that the cleaning liquid and clean water can be mixed according to the preset ratio, thereby ensuring that the cleaning liquid reaches the correct concentration each time it is used, improving the cleaning effect. Moreover, the correct ratio of cleaning liquid can avoid unnecessary waste, remove dirt more effectively, reduce the need for repeated cleaning, and improve cleaning efficiency.

[0052] Furthermore, since the liquid passage 21 is located on the sealing plug 2, different ratios of cleaning liquid and clean water can be achieved by replacing the sealing plug 2 with different sizes or numbers of liquid passage 21 (for example, increasing the number of liquid passage 21 on the sealing plug 2 or widening the width of the liquid passage 21), thereby improving the efficiency of changing the ratio of cleaning liquid and clean water.

[0053] According to some optional embodiments of the present invention, combined with Figures 1-3 As shown, the housing 1 and the sealing plug 2 together define the receiving cavity 3. The receiving cavity 3 is connected to the liquid inlet 11 and the liquid passage 21 respectively. The cleaning liquid in the cleaning liquid tank flows into the receiving cavity 3 through the liquid inlet 11. The cleaning liquid in the receiving cavity 3 can only flow to the liquid outlet 12 along the liquid passage 21 when it flows to the liquid passage 21. The receiving cavity 3 plays a certain role in buffering the flow rate of the cleaning liquid. The flow rate of the cleaning liquid in the liquid passage 21 is more uniform, ensuring the stability of the ratio of cleaning liquid and clean water.

[0054] For example, the housing 1 has an opening, the sealing plug 2 is disposed at the opening, and a portion of the inner wall of the housing 1 and the sealing plug 2 together define the receiving cavity 3.

[0055] Specifically, in combination Figures 1-3 As shown, the liquid inlet 11 is located at one end of the housing 1, the liquid outlet 12 is located on the outer periphery of the housing 1, and the sealing plug 2 is spaced apart from one end of the housing 1 to jointly define the receiving cavity 3 with the housing 1.

[0056] This arrangement can change the flow direction of the fluid, which helps to shorten the axial distance between the outlet 12 and the inlet 11, thereby shortening the axial dimension of the housing 1 and reducing the space occupied by the proportioning mechanism 100. It also allows the sealing plug 2 to provide a liquid passage 21 that can flow to the outlet 12 for the cleaning fluid, while ensuring the sealing effect of the other end of the sealing plug 2 and the inner wall of the housing 1 in the circumferential direction. Furthermore, the cavity 3 defined by the sealing plug 2 and the housing 1 can temporarily accumulate and buffer the cleaning fluid, thereby making the flow rate of the cleaning fluid in the liquid passage 21 more uniform.

[0057] Furthermore, combined Figures 3-5 As shown, the liquid passage 21 includes a first liquid passage section 211 and a second liquid passage section 212. The first liquid passage section 211 is disposed on the outer periphery of the sealing plug 2, and one end of the first liquid passage section 211 is connected to the receiving cavity 3. The second liquid passage section 212 is disposed on the outer periphery of the sealing plug 2, and the other end of the second liquid passage section 212 is connected to the first liquid passage section 211. The second liquid passage section 212 is connected to the liquid outlet 12. The first liquid passage section 211 and the second liquid passage section 212 extend in different directions.

[0058] In other words, the cleaning fluid in the receiving cavity 3 can flow sequentially from one end of the first liquid passage section 211 to the other end, then to the second liquid passage section 212, and finally flow along the second liquid passage section 212 to the outlet 12, where it mixes with clean water. This allows the cleaning fluid to smoothly pass through the sealing plug 2 and mix with clean water, thus achieving the desired mixing ratio of cleaning fluid and clean water. The first liquid passage section 211 and the second liquid passage section 212 extend in different directions, allowing the liquid passages 21 to extend towards the outlet 12 in different directions from the sealing plug 2, ensuring that the cleaning fluid can flow smoothly from the receiving cavity 3 to the outlet 12.

[0059] Specifically, in combination Figures 3-5 As shown, the first liquid passage section 211 is straight, and the length direction of the first liquid passage section 211 is parallel to the central axis of the sealing plug 2; the second liquid passage section 212 is arc-shaped or annular, and the second liquid passage section 212 is arranged around the central axis of the sealing plug 2.

[0060] Understandably, the first liquid passage section 211 extends linearly along the axial direction of the sealing plug 2, which facilitates the cleaning fluid to approach the outlet 12 axially. The second liquid passage section 212 extends circumferentially along the outer periphery of the sealing plug 2, which facilitates the cleaning fluid to approach the outlet 12 on the outer periphery of the housing 1 along the outer periphery of the sealing plug 2. This not only allows the cleaning fluid to flow smoothly to the outlet 12, but also reduces manufacturing difficulty and improves manufacturing efficiency while ensuring the structural strength of the seal. Specifically, the outlet 12 is located in the middle of the second liquid passage section 212 along the axial direction of the sealing plug 2.

[0061] Furthermore, since there is only one first liquid passage section 211, the number of first liquid passage sections 211 manufactured can be reduced, thus reducing the manufacturing workload; it can also control the flow rate of the cleaning fluid, which is conducive to achieving a small ratio of cleaning fluid and clean water, reducing the waste of cleaning fluid.

[0062] Alternatively, there may be multiple first liquid passage sections 211, which are spaced apart in the circumferential direction of the sealing plug 2. This can increase the flow rate of the cleaning liquid in the same time, thereby increasing the proportion of the cleaning liquid in the mixture. This is beneficial for achieving a large ratio of cleaning liquid to clean water, and is suitable for cleaning situations with severe dirt.

[0063] According to some optional embodiments of the present invention, combined with Figures 3-5 As shown, the sealing plug 2 is detachably disposed inside the housing 1 to allow for replacement with different types of sealing plugs 2.

[0064] Specifically, different types of sealing plugs 2 can have different numbers and sizes of liquid passages 21. Users can flexibly replace different types of sealing plugs 2 according to the cleaning situation. The sealing plugs 2 are detachably set in the housing 1, which can improve the convenience of disassembling and replacing the sealing plugs 2, thereby improving the flexibility of changing the ratio of the mixing mechanism 100.

[0065] According to some optional embodiments of the present invention, combined with Figures 3-5 As shown, the housing 1 has a first stepped portion 13, and the sealing plug 2 has a second stepped portion 24, with the first stepped portion 13 and the second stepped portion 24 cooperating.

[0066] This arrangement serves two purposes: firstly, it facilitates the sealing plug 2 to form a sealing effect with the housing 1 along its axial direction, improving the sealing performance between the sealing plug 2 and the housing 1; secondly, it also creates an axial stop between the sealing plug 2 and the housing 1, preventing the sealing plug 2 from extending too far into the housing 1 or not extending into the housing 1 properly, ensuring the accuracy of the assembly position between the sealing plug 2 and the housing 1, and thus ensuring that the liquid passage 21 on the sealing plug 2 can be smoothly connected to the liquid outlet 12 on the housing 1.

[0067] Optionally, a sealing ring 22 is provided on the outer periphery of the sealing plug 2. The sealing ring 22 contacts the inner wall of the housing 1. This arrangement can help the sealing ring 22 to further form a sealing effect with the inner wall of the housing 1 in the circumferential direction of the sealing plug 2, effectively preventing the risk of liquid leakage from the gap between the sealing plug 2 and the housing 1, and also reducing the wear between the sealing plug 2 and the housing 1, and extending the service life of the sealing plug 2.

[0068] According to some optional embodiments of the present invention, combined with Figures 1-3 As shown, the cleaning equipment also includes a pump body and a first control valve 4. The pump body is connected to the proportioning mechanism 100, and the first control valve 4 is disposed in the proportioning mechanism 100. Moreover, the first control valve 4 selectively closes the liquid inlet 11.

[0069] For example, when the cleaning equipment is performing cleaning work, the first control valve 4 opens the inlet 11, and the cleaning liquid in the cleaning liquid tank flows through the inlet 11 into the proportioning mechanism 100 to participate in the proportioning work with clean water; when the cleaning equipment stops performing cleaning work, the first control valve 4 closes the inlet 11 to prevent the cleaning liquid in the cleaning liquid tank from continuing to flow into the proportioning mechanism 100, thus avoiding waste of cleaning liquid and preventing clean water or mixed liquid in the proportioning mechanism 100 from flowing back into the cleaning liquid tank through the inlet 11, thus preventing the risk of cross-contamination in the cleaning liquid tank.

[0070] Specifically, the first control valve 4 is adapted to open when the pump body is turned on. When the pump body starts working, the first control valve 4 also opens the inlet 11 at the same time. At this time, the cleaning liquid in the cleaning liquid tank can flow into the proportioning mechanism 100 through the inlet 11. The pump body generates a suction force on the cleaning liquid inside the proportioning mechanism 100. The cleaning liquid in the cleaning liquid tank can continuously replenish the proportioning mechanism 100, which is conducive to the continuous suction of the mixed liquid to the required position, thereby improving the continuity and smoothness of the cleaning work.

[0071] Specifically, the first control valve 4 is an umbrella valve, and the umbrella valve includes a valve seat 41 and a valve core 42. The valve seat 41 is disposed in the proportioning mechanism 100 and is located on one side of the liquid inlet 11. The valve core 42 is connected to the valve seat 41 and is located inside the proportioning mechanism 100. The valve core 42 is constructed in a plate shape and closes the liquid inlet 11. The valve core 42 is adapted to deform under the action of external force to open the liquid inlet 11.

[0072] It is understandable that the valve seat 41 is connected to the proportioning mechanism 100, and the valve seat 41 provides force support for the valve core 42. The valve core 42 in the proportioning mechanism 100 is constructed as a plate with a large surface area, which is conducive to the rapid deformation of the valve core 42 after being subjected to external force, thereby improving the sensitivity and responsiveness of the first control valve 4 in opening and closing the liquid inlet 11.

[0073] Optionally, the first control valve 4 is a one-way valve, which allows the cleaning fluid in the cleaning fluid tank to flow unidirectionally into the mixing mechanism 100. The liquid in the mixing mechanism 100 cannot flow back into the cleaning fluid tank, thereby ensuring the purity of the cleaning fluid, avoiding the risk of cross-flow and dilution of the cleaning fluid in the cleaning fluid tank, and improving the accuracy of each mixing (that is, the subsequent mixing of cleaning fluid and water).

[0074] Alternatively, the first control valve 4 can be a solenoid valve. A solenoid valve is an automatic valve that uses electromagnetic principles to control the flow of fluids (such as gas and liquid). It drives the valve core 42 through the magnetic field generated by the electromagnetic coil, thereby realizing the function of opening, closing or regulating the fluid in the pipeline. As arranged as above, the solenoid valve can control the opening and closing of the liquid inlet 11 and adjust the size of the liquid inlet 11 in a timely and rapid manner, thereby improving the control accuracy of the cleaning liquid flowing from the cleaning liquid tank to the proportioning mechanism 100 and ensuring the accuracy of each proportion.

[0075] According to some optional embodiments of the present invention, combined with Figures 1-3 As shown, the cleaning equipment also includes a second control valve 5, which is located between the liquid outlet 12 and the clean water tank, and the second control valve 5 selectively opens and closes the clean water tank.

[0076] For example, when the cleaning equipment is performing cleaning work, the second control valve 5 opens the flow channel between the outlet 12 and the clean water tank. The clean water flowing into the proportioning mechanism 100 from the clean water tank can mix with the cleaning liquid flowing out of the outlet 12 to achieve the proportioning of clean water and cleaning liquid. When the cleaning equipment stops performing cleaning work, the second control valve 5 closes the flow channel between the outlet 12 and the clean water tank. This can prevent the clean water flowing into the proportioning mechanism 100 from continuing to mix with the cleaning liquid flowing out of the outlet 12, thus avoiding waste of clean water. It can also prevent the cleaning liquid or mixture in the proportioning mechanism 100 from flowing back into the clean water tank through the outlet 12, thus preventing the risk of cross-contamination in the clean water tank.

[0077] Specifically, in combination Figures 1-3 As shown, the mixing mechanism 100 also includes a water inlet connector 6 and a liquid outlet connector 7. The water inlet connector 6 is connected to the clean water tank, and the liquid outlet connector 7 is located in the mixing mechanism 100. The liquid outlet connector 7 is connected to the liquid outlet 12 and the water inlet connector 6 respectively, and the liquid outlet connector 7 has a mixed liquid outlet.

[0078] Understandably, the inlet connector 6 is used to guide the clean water in the clean water tank to flow smoothly into the mixing mechanism 100. The outlet connector 7 is connected to the outlet 12 and the inlet connector 6 respectively. That is, the cleaning liquid can flow to the outlet connector 7 through the outlet 12, and the clean water can flow to the outlet connector 7 through the inlet connector 6. The mixed liquid outlet of the outlet connector 7 can mix and proportion the cleaning liquid and clean water in the outlet connector 7 before flowing the mixed liquid to the relevant structure, thereby successfully achieving the mixing and proportioning effect of the mixing mechanism 100 on the cleaning liquid and clean water.

[0079] Furthermore, the cleaning equipment also includes a water pipe connected between the clean water tank and the water inlet connector 6; wherein, the second control valve 5 is located on the water pipe or the water inlet connector 6.

[0080] For example, the water pipe can be a flexible water pipe, which can bend and connect the clear water tank and the proportioning mechanism 100 at different locations by taking advantage of its flexibility and deformability, thereby improving the spatial arrangement flexibility of the clear water tank and the proportioning mechanism 100; the water pipe can also be a rigid water pipe, which can strengthen the structural strength of the water pipe and thus improve the structural reliability of the water pipe.

[0081] In addition, the second control valve 5 can be set at the water guide pipe or at the water inlet connector 6. The positions of the second control valve 5 can effectively control the flow of clean water between the clean water tank and the proportioning mechanism 100, thereby improving the spatial arrangement flexibility and versatility of the second control valve 5.

[0082] Optionally, the second control valve 5 is a one-way valve, which allows only the clean water in the clean water tank to flow unidirectionally into the mixing mechanism 100. The liquid in the mixing mechanism 100 cannot flow back into the clean water tank, thereby ensuring the purity of the clean water, avoiding the risk of cross-flow and dilution of the clean water in the clean water tank, and improving the accuracy of each mixing (that is, the subsequent mixing of clean water and cleaning solution).

[0083] Alternatively, the second control valve 5 can be a solenoid valve. A solenoid valve is an automatic valve that uses electromagnetic principles to control the flow of fluids (such as gas and liquid). It drives the valve core 42 through the magnetic field generated by the electromagnetic coil, thereby realizing the function of opening, closing or regulating the fluid in the pipeline. As arranged as above, the flow of clean water between the clean water tank and the proportioning mechanism 100 can be adjusted in a timely and rapid manner by the solenoid valve, thereby improving the control accuracy of the flow of clean water from the clean water tank to the housing 1 and ensuring the accuracy of each proportion.

[0084] Combination Figures 1-3 As shown, the cleaning device according to the second aspect of the present invention includes a cleaning liquid tank, a clean water tank, a mixing mechanism 100, and a first control valve 4. The mixing mechanism 100 has an inlet 11, an outlet 12, and a liquid passage 21. The inlet 11 is connected to the cleaning liquid tank, and the outlet 12 is connected to the clean water tank so that the cleaning liquid and clean water form a mixture. The liquid passage 21 connects the inlet 11 and the outlet 12. The first control valve 4 is disposed in the mixing mechanism 100, and the first control valve 4 selectively opens and closes the inlet 11.

[0085] The inlet 11 and outlet 12 of the mixing mechanism 100 are connected to the cleaning solution tank and the clean water tank, respectively. The cleaning solution in the cleaning solution tank can flow into the mixing mechanism 100 through the inlet 11. After flowing out of the outlet 12, the cleaning solution in the cleaning solution tank can mix with the clean water flowing into the mixing mechanism 100 from the clean water tank to form a mixed solution. This facilitates the mixing effect of the cleaning solution and clean water in the mixing mechanism 100. Moreover, the cleaning solution and clean water in the mixing mechanism 100 can only be interconnected through the liquid passage 21 on the mixing mechanism 100. Since the flow cross-sectional area of ​​the liquid passage 21 and the flow cross-sectional area of ​​the outlet 12 are fixed, the mixing ratio of the cleaning solution and clean water is relatively fixed. This ensures that the cleaning solution and clean water can be mixed according to the preset ratio, thereby ensuring that the cleaning solution reaches the correct concentration each time it is used and improving the stability of the mixing effect.

[0086] Specifically, in combination Figures 1-3 As shown, the first control valve 4 is an umbrella valve, and the umbrella valve includes a valve seat 41 and a valve core 42. The valve seat 41 is disposed on the proportioning mechanism 100 and is located on one side of the liquid inlet 11. The valve core 42 is connected to the valve seat 41 and is located inside the proportioning mechanism 100. The valve core 42 is plate-shaped and closes the liquid inlet 11.

[0087] It is understandable that the valve seat 41 is connected to the proportioning mechanism 100, and the valve seat 41 provides force support for the valve core 42. The valve core 42 inside the housing 1 is constructed as a plate with a large surface area, which is conducive to the rapid deformation of the valve core 42 after being subjected to external force, thereby improving the sensitivity and responsiveness of the first control valve 4 in opening and closing the liquid inlet 11.

[0088] Optionally, the first control valve 4 is a one-way valve, which allows the cleaning fluid in the cleaning fluid tank to flow unidirectionally into the mixing mechanism 100. The liquid in the mixing mechanism 100 cannot flow back into the cleaning fluid tank, thereby ensuring the purity of the cleaning fluid, avoiding the risk of cross-flow and dilution of the cleaning fluid in the cleaning fluid tank, and improving the accuracy of each mixing (that is, the subsequent mixing of cleaning fluid and water).

[0089] Alternatively, the first control valve 4 can be a solenoid valve. The solenoid valve can open, close or regulate the fluid in the pipeline. As arranged as above, the flow of clean water between the clean water tank and the proportioning mechanism 100 can be adjusted in a timely and rapid manner by the solenoid valve, thereby improving the control accuracy of the flow of clean water from the clean water tank to the proportioning mechanism 100 and ensuring the accuracy of each proportion.

[0090] Furthermore, combined Figures 1-5As shown, the proportioning mechanism 100 includes a housing 1 and a sealing plug 2. The housing 1 has a liquid inlet 11 and a liquid outlet 12. The sealing plug 2 is disposed inside the housing 1 and has a liquid passage 21. The housing 1 and the sealing plug 2 together define a receiving cavity 3, which is connected to the liquid inlet 11 and the liquid passage 21 respectively. The valve core 42 is located inside the receiving cavity 3 and is attached to the wall of the housing 1.

[0091] As arranged as above, the cleaning fluid in the cleaning fluid tank flows into the receiving cavity 3 through the inlet 11. The cleaning fluid in the receiving cavity 3 can only flow to the outlet 12 along the liquid passage 21 when it reaches the liquid passage 21. The receiving cavity 3 plays a certain role in buffering the flow rate of the cleaning fluid, thereby improving the uniformity of the flow rate of the cleaning fluid to the clean water position, and thus ensuring the stability of the ratio of cleaning fluid and clean water.

[0092] Combination Figures 1-3 As shown, the cleaning device according to the third aspect embodiment of the present invention includes a cleaning liquid tank, a clean water tank, a mixing mechanism 100, a first control valve 4, and a second control valve 5. The mixing mechanism 100 has an inlet 11, an outlet 12, and a liquid passage 21. The inlet 11 is connected to the cleaning liquid tank, and the outlet 12 is connected to the clean water tank so that the cleaning liquid and clean water form a mixture. The liquid passage 21 connects the inlet 11 and the outlet 12. The first control valve 4 is disposed in the mixing mechanism 100 and selectively opens and closes the inlet 11. The second control valve 5 is disposed between the outlet 12 and the clean water tank and selectively opens and closes the clean water tank.

[0093] The mixing mechanism 100 has an inlet 11 and an outlet 12 connected to a cleaning solution tank and a clean water tank, respectively. The cleaning solution in the cleaning solution tank can flow into the mixing mechanism 100 through the inlet 11. After flowing out of the outlet 12, the cleaning solution in the cleaning solution tank can mix with the clean water flowing into the mixing mechanism 100 from the clean water tank to form a mixed solution. This facilitates the mixing of the cleaning solution and clean water in the mixing mechanism 100. Moreover, the cleaning solution and clean water in the mixing mechanism 100 can only be interconnected through the liquid passage 21 on the mixing mechanism 100. Since the flow cross-sectional area of ​​the liquid passage 21 and the flow cross-sectional area of ​​the outlet 12 are fixed, the mixing ratio of the cleaning solution and clean water is relatively fixed. This ensures that the cleaning solution and clean water can be mixed according to the preset ratio, thereby ensuring that the cleaning solution reaches the correct concentration each time it is used and improving the stability of the mixing ratio. In addition, the second control valve 5 can effectively control the flow of clean water between the clean water tank and the mixing mechanism 100, thereby ensuring the accuracy and stability of the mixing operation.

[0094] Specifically, the cleaning equipment also includes a pump body connected to the proportioning mechanism 100, and the first control valve 4 and the second control valve 5 are both adapted to open when the pump body is turned on.

[0095] It is understandable that the pump body is connected to the proportioning mechanism 100. When the pump body starts working, the first control valve 4 opens the inlet 11. At this time, the cleaning liquid in the cleaning liquid tank can flow into the proportioning mechanism 100 through the inlet 11. The second control valve 5 opens the flow channel between the outlet 12 and the clean water tank. The clean water flowing into the proportioning mechanism 100 from the clean water tank can mix with the cleaning liquid flowing out of the outlet 12 to achieve the proportioning of clean water and cleaning liquid. The pump body can generate suction force on the cleaning liquid and clean water inside the proportioning mechanism 100. The cleaning liquid in the cleaning liquid tank and the clean water in the clean water tank can continuously replenish the proportioning mechanism 100, which is beneficial for the cleaning liquid and clean water inside the proportioning mechanism 100 to be mixed and then continuously pumped to the required position, thereby improving the continuity and smoothness of the proportioning work.

[0096] Furthermore, combined Figures 1-5 As shown, the mixing mechanism 100 includes a housing 1, a sealing plug 2, a water inlet connector 6, and a liquid outlet connector 7. The housing 1 has a liquid inlet 11 and a liquid outlet 12. The sealing plug 2 is disposed inside the housing 1 and has a liquid passage 21. The water inlet connector 6 is connected to the clean water tank. The liquid outlet connector 7 is disposed in the housing 1 and is connected to both the liquid outlet 12 and the water inlet connector 6. The liquid outlet connector 7 has a mixed liquid outlet, which is connected to the pump body.

[0097] The cleaning fluid in the cleaning fluid tank flows into the housing 1 through the inlet 11. The cleaning fluid in the housing 1 can only flow to the outlet 12 along the liquid passage 21 when it reaches the liquid passage 21. This allows the sealing plug 2 to buffer the flow rate of the cleaning fluid to a certain extent, thereby improving the uniformity of the flow rate of the cleaning fluid to the clean water position and ensuring the stability of the ratio of cleaning fluid and clean water. In addition, the pump body is connected to the mixed liquid outlet of the liquid outlet 7, so that the cleaning fluid and clean water in the liquid outlet 7 can be mixed and proportioned before the mixed liquid is pumped to the relevant structure, which is conducive to the pumping of the mixed liquid to the cleaning surface.

[0098] Furthermore, the cleaning equipment also includes a water pipe that connects the clean water tank and the water inlet connector 6; wherein, the first control valve 4 is located in the housing 1, and the second control valve 5 is located in the water pipe or the water inlet connector 6.

[0099] For example, the water pipe can be a flexible water pipe, which can bend and connect the clear water tank and the proportioning mechanism 100 at different locations or distances, improving the spatial arrangement flexibility of the clear water tank and the proportioning mechanism 100. Alternatively, the water pipe can be a rigid water pipe, which strengthens its structural strength and improves its structural reliability. Furthermore, the first control valve 4 is located on the housing 1, improving the structural compactness of the proportioning mechanism 100. The second control valve 5 can be located at the water pipe or at the water inlet connector 6. Both locations of the second control valve 5 effectively control the flow of clear water between the clear water tank and the proportioning mechanism 100, thus improving the spatial arrangement flexibility and versatility of the second control valve 5.

[0100] According to some optional embodiments of the present invention, combined with Figures 1-3 As shown, the first control valve 4 is an umbrella valve, and the umbrella valve includes a valve seat 41 and a valve core 42. The valve seat 41 is disposed on the proportioning mechanism 100 and is located on one side of the liquid inlet 11. The valve core 42 is connected to the valve seat 41 and is located inside the proportioning mechanism 100. The valve core 42 is plate-shaped and closes the liquid inlet 11.

[0101] Specifically, the valve seat 41 is connected to the proportioning mechanism 100. The valve seat 41 can provide force support for the valve core 42. The valve core 42 inside the housing 1 is constructed as a sheet with a large surface area. This is beneficial for the valve core 42 to deform quickly after being subjected to external force, thereby improving the sensitivity and responsiveness of the first control valve 4 in opening and closing the liquid inlet 11. Moreover, when the cleaning equipment is not performing proportioning work, the valve core 42 is in the closed state of the liquid inlet 11. Only when the cleaning equipment performs proportioning work, the valve core 42 opens the liquid inlet 11 to prepare the required concentration of cleaning liquid and spray it on the cleaning surface, which is beneficial to improving the cleaning effect.

[0102] Optionally, the first control valve 4 is a one-way valve, which allows the cleaning fluid in the cleaning fluid tank to flow unidirectionally into the mixing mechanism 100. The liquid in the mixing mechanism 100 cannot flow back into the cleaning fluid tank, thereby ensuring the purity of the cleaning fluid and avoiding the risk of cross-flow dilution of the cleaning fluid in the cleaning fluid tank, thereby improving the accuracy of each mixing (that is, the subsequent mixing of cleaning fluid and clean water).

[0103] Alternatively, the first control valve 4 can be a solenoid valve. The solenoid valve drives the valve core 42 through the magnetic field generated by the electromagnetic coil, which can realize the opening, closing or regulation of the fluid in the pipeline. As arranged as above, the first control valve 4 can quickly and accurately control the flow of cleaning fluid between the cleaning fluid tank and the proportioning mechanism 100, thereby improving the control accuracy of the cleaning fluid flowing from the cleaning fluid tank to the housing 1 and ensuring the accuracy of each proportion.

[0104] Alternatively, the second control valve 5 is a one-way valve, which allows only the clean water in the clean water tank to flow unidirectionally into the mixing mechanism 100. The liquid in the mixing mechanism 100 cannot flow back into the clean water tank, thereby ensuring the purity of the clean water, avoiding the risk of cross-flow and dilution of the clean water in the clean water tank, and improving the accuracy of each mixing (that is, the subsequent mixing of clean water and cleaning solution).

[0105] Alternatively, the second control valve 5 is a solenoid valve, which can quickly and accurately adjust the flow of clean water between the clean water tank and the proportioning mechanism 100, thereby improving the control accuracy of the flow of clean water from the clean water tank to the proportioning mechanism 100 and ensuring the accuracy of each proportion.
