[0002] This application claims priority to Chinese patent application No. 202111650972.1, filed on December 30, 2021, entitled "Liquid Storage Container, Separation Device and Cleaning Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This invention relates to the field of cleaning technology, and more specifically to a liquid storage container and cleaning equipment. Background Technology

[0004] Cleaning equipment, such as floor scrubbers and mops, sprays cleaning liquid onto the floor during the cleaning process to achieve efficient dirt removal. The resulting wastewater, containing impurities, flows into a wastewater tank through an inlet pipe under the action of a negative pressure generator for storage, while the gas is discharged from the wastewater tank, forming a complete suction and circulation system. However, traditional cleaning equipment suffers from poor water-vapor separation within the wastewater tank, resulting in a significant amount of moisture mixed in with the gas discharged from the tank. This moisture can easily enter the negative pressure generator, causing corrosion or even damage, thus affecting the lifespan of the cleaning equipment. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is that traditional cleaning equipment is prone to damage due to insufficient water vapor separation.

[0006] To solve the above-mentioned technical problems, the present invention provides a liquid storage container, which is used in conjunction with a negative pressure generator to recover the gas-liquid mixture of the surface to be cleaned. The liquid storage container includes:

[0007] The housing has a liquid storage chamber, and a liquid inlet and an air outlet connected to the liquid storage chamber, and the air outlet is connected to the negative pressure generator;

[0009] The second rotating body is rotatably disposed within the liquid storage cavity;

[0010] The rotating component is located between the liquid inlet and the air outlet, and the second rotating body is located between the rotating component and the air outlet. The liquid inlet is oriented towards the rotating component. When the negative pressure generator is activated and both the rotating component and the second rotating body rotate, the gas-liquid mixture entering the storage chamber from the liquid inlet is first separated by the rotating component and then by the second rotating body to separate the liquid from the gas-liquid mixture. The separated liquid remains in the storage chamber.

[0011] Optionally, in the liquid storage container, the rotating component and the second rotating body are coaxially arranged.

[0012] Optionally, the liquid storage container further includes a drive structure connected to at least one of the rotating member and the second rotating body.

[0013] Optionally, the liquid storage container further includes a lid, and the drive structure is installed at the bottom of the lid.

[0014] Optionally, in the liquid storage container, the rotating component is arranged in a flat plate shape, and the rotating component has at least one first blade protruding from the side facing the liquid inlet.

[0015] Optionally, in the liquid storage container, the rotating component and the second rotating body are integrally formed; or,

[0016] The rotating component and the second rotating body are detachably connected.

[0017] Optionally, in the liquid storage container, the second rotating body includes a plurality of second blades, which are spaced apart along the circumference of the rotating member.

[0018] Optionally, in the liquid storage container, the air outlet is located inside the plurality of second blades, and the gap between two adjacent second blades connects the liquid storage chamber and the air outlet.

[0019] Optionally, in the liquid storage container, the plurality of second blades and the rotating component are together enclosed in a cone shape.

[0020] The present invention also provides a cleaning device, including the aforementioned liquid storage container.

[0021] The technical solution provided by this invention has the following advantages:

[0022] The liquid storage container provided by this invention includes a housing, a rotating component and a second rotating body rotatably disposed within the housing, wherein the rotating component is located between the liquid inlet and the air outlet, and the second rotating body is located between the rotating body and the air outlet, with the liquid inlet facing the rotating component. When the negative pressure generator is activated and both the rotating component and the second rotating body rotate, the gas-liquid mixture entering the storage chamber from the liquid inlet is first separated by the rotating component, and then by the second rotating body, to separate the liquid from the gas-liquid mixture. The separated liquid remains in the storage chamber, allowing the gas and liquid to be fully separated, thereby reducing the amount of water carried when the gas flows through the negative pressure generator, effectively protecting the negative pressure generator and extending the service life of the liquid storage container.

[0035] Example 1

[0036] This embodiment provides a liquid storage container 100. Please refer to [link / reference]. Figures 1 to 2 The liquid storage container 100 is used in conjunction with the negative pressure generator 25 to recover the gas-liquid mixture on the surface to be cleaned. Specifically, the liquid storage container 100 includes a housing 1, a rotating component 22, and a second rotating body 23. The housing 1 has a liquid storage chamber, an inlet 15 and an outlet 14 connected to the liquid storage chamber. The outlet 14 is connected to the negative pressure generator 25, which can be a fan or a vacuum pump, etc. When the negative pressure generator 25 operates, a negative pressure is formed in the liquid storage chamber, so that the gas-liquid mixture on the surface to be cleaned can enter the liquid storage chamber from the inlet 15 for storage, thereby achieving the cleaning of the surface to be cleaned. The rotating component 22 and the second rotating body 23 are both rotatably disposed in the liquid storage chamber. The rotating component 22 is located at the inlet 15 and the outlet 23. Between the air outlet 14, the second rotating body 23 is located between the rotating part 22 and the air outlet 14. The liquid inlet 15 is set towards the rotating part 22. When the negative pressure generator 25 is started and both the rotating part 22 and the second rotating body 23 rotate, the gas-liquid mixture entering the liquid storage chamber from the liquid inlet 15 is first separated by the rotating part 22, and then separated by the second rotating body 23, so as to separate the liquid in the gas-liquid mixture. The separated liquid is stored in the liquid storage chamber. When the gas is discharged from the air outlet 14, there is less water mixed in. Therefore, when the gas flows through the negative pressure generator 25, it will not cause corrosion of the negative pressure generator 25, effectively protecting the negative pressure generator 25 and extending the service life of the cleaning equipment.

[0037] It should be noted that when the liquid storage container 100 is placed vertically, preferably, as shown in the figure below. Figure 2 As shown, the air outlet 14 is located at the top of the liquid storage container 100. Along the top-to-bottom direction of the housing 1, a second rotating body 23, a rotating component 22, and a liquid inlet 15 are arranged sequentially. All descriptions of orientation in this invention are based on this arrangement. Under the action of the negative pressure generator 25, the airflow mixture can be sprayed upwards from the liquid inlet 15 onto the rotating component 22. The rotating component 22 performs the first separation, separating the liquid from the airflow mixture. The airflow mixture then undergoes a second separation via the second rotating body 23, resulting in more thorough liquid separation and a better separation effect.

[0038] Preferably, the rotating component 22 and the second rotating body 23 are coaxially arranged, so that when both the rotating component 22 and the second rotating body 23 rotate, the rotation is more stable, making the liquid storage container 100 work more stably.

[0039] In one embodiment, combined with Figure 5 and Figure 6 As shown, the rotating component 22 and the second rotating body 23 can be integrated into one unit, which makes the structure simpler, easier to install, and more stable when the rotating component 22 and the second rotating body 23 rotate.

[0040] In another embodiment, the rotating member 22 and the second rotating body 23 can be detachably connected, so that the rotating member 22 and the second rotating body 23 can be replaced individually during maintenance, resulting in lower operating costs and more convenient maintenance.

[0041] Furthermore, combined Figures 3 to 5 As shown, the liquid storage container 100 also includes a drive structure 24, which is connected to at least one of the rotating member 22 and the second rotating body 23. The drive structure 24 drives the rotating member 22 to rotate, thereby driving the second rotating body 23 to rotate. Alternatively, the drive structure 24 drives the second rotating body 23 to rotate, thereby driving the rotating member 22 to rotate. One drive structure 24 can drive the rotating member 22 and the second rotating body 23 to rotate simultaneously, which is lower in cost, has better synchronization, and is more stable in operation.

[0042] Furthermore, such as Figure 1 and Figure 3 As shown, the liquid storage chamber has an upward-facing opening. The liquid storage container 100 also includes a cover 12, which is placed over the opening. An air outlet 14 is located on the cover 12. A drive structure 24 is installed at the bottom of the cover 12, and at least a portion of the drive shaft of the drive structure 24 can extend from the bottom of the cover 12 to connect with the rotating member 22 and / or the second rotating body 23.

[0043] Preferably, such as Figure 5 and Figure 6 As shown, the rotating member 22 is arranged in the shape of a flat plate. At least one first blade 212 protrudes from the side of the rotating member 22 facing the liquid inlet 15. The rotation of the rotating member 22 can drive the first blade 212 to rotate together, so that the gas-liquid mixture sprayed from the liquid inlet 15 to the rotating member 22 can be dispersed under the action of the first blade 212, thereby achieving a better separation effect.

[0044] The second rotating body 23 can be configured in various ways. Preferably, it is combined with... Figure 5 and Figure 6As shown, the second rotating body 23 includes multiple second blades 231, which are arranged at intervals along the circumference of the rotating member 22. The rotation of the multiple second blades 231 creates a centrifugal force, thereby separating the gas-liquid mixture flowing through the multiple second blades 231, so that the liquid is completely separated and stored in the liquid storage chamber, so that the discharged gas contains less liquid and can better protect the negative pressure generator 25.

[0045] Furthermore, the air outlet 14 is located inside the plurality of second blades 231. The gap between two adjacent second blades 231 connects the liquid storage chamber and the air outlet 14. The gas-liquid mixture entering the liquid storage chamber from the liquid inlet 15 undergoes the first separation by the rotating member 22. A portion of the gas-liquid mixture flows toward the second blade 231 with the flow of gas for the second separation, so that the liquid can be completely separated and the separation effect is better. The separated gas can flow from the gap between the plurality of blades to the air outlet 14, thereby being discharged from the liquid storage chamber and flowing toward the negative pressure generator 25. The gas is drier and can therefore better protect the negative pressure generator 25.

[0046] Furthermore, multiple second blades 231 and rotating member 22 are arranged together to form a cone shape, with the flared end of the cone facing upwards to surround the air outlet 14. The rotating member 22 is located at the constricted end of the cone, so that the gas-liquid mixture can be completely separated by the second rotating body 23 before being discharged, thus achieving more thorough separation.

[0047] Example 2

[0048] This embodiment provides a cleaning device, which includes the aforementioned liquid storage container 100. The liquid storage chamber of the liquid storage container 100 can store the wastewater generated during the cleaning process. The rotating part 22 and the second rotating body 23 of the liquid storage container 100 perform secondary separation on the wastewater entering the liquid storage chamber, so that the liquid can be better separated, preventing water from entering the negative pressure generator 25 and affecting the normal operation of the negative pressure generator 25. This can extend the service life of the cleaning device. Moreover, after separating the wastewater entering the liquid storage chamber, the liquid contains less gas, so the liquid storage capacity can be increased.

[0049] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. Based on the embodiments of the present invention, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the scope of protection of the present invention.
