[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0019] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0020] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0021] Referring to the drawings in the specification, an RO filter element anti-leakage structure includes a water channel 10 and a filter bottle 20 of the RO filter element, and also includes a rotating disk 30 arranged between the water channel and the filter bottle. The water inlet of the rotating disk can be connected to the water inlet of the filter bottle, and the water inlet of the water channel can be connected to the water inlet of the rotating disk. A sealing ring 60 is provided between the filter bottle and the rotating disk, and between the rotating disk and the water channel. After installation, the water inlets of the connected components can realize the flow of water, and the sealing ring ensures that there will be no leakage during normal use; the filter bottle and the rotating disk can rotate relative to the water channel, or in other words, the filter bottle It can not only drive the rotating disk to rotate relative to the main body, but also rotate independently relative to the rotating disk and the main body. When the filter bottle rotates relative to the rotating disk, the water outlet of the filter bottle and the water outlet of the rotating disk can be staggered and not connected. The end face seal is adopted between the rotating disk and the filter bottle, and the water outlets are staggered. These water outlets are not conductive, and water flow no longer flows. When the rotating disk rotates relative to the water channel, the water outlet of the water channel and the water outlet of the rotating disk can be staggered and not connected. Similarly, the end face seal is adopted between the rotating disk and the water channel, and the water outlets are staggered. These water outlets are not conductive, and water flow no longer flows.

[0022] Preferably, the water outlet of the filter bottle includes a pure water outlet 21, and of course also includes a raw water inlet 22 and a wastewater outlet 23. A first check valve 24 is provided at the pure water outlet. When the filter bottle is separated from the rotating disk portion 42, the pure water outlet stops discharging water under the action of the first check valve. This ensures that the filter bottle does not leak after it is removed. The rotating disk also includes a push block 31, which can be connected to the first check valve. When the rotating disk and filter bottle are installed together, the push block can open the first check valve, allowing the pure water in the filter bottle to flow out of the pure water outlet.

[0023] Furthermore, the water inlet of the rotating disk includes a pure water inlet 32, and also includes a raw water inlet 33 and a waste water inlet 34. The water inlet of the water channel includes a pure water outlet 11 that can be connected with the pure water inlet, and also includes a raw water inlet 12 and a waste water outlet 13. This water inlet is connected according to function, which is the same as the existing technology and will not be elaborated on again. The pure water inlet can be connected with the pure water outlet. A second check valve 35 is provided at the pure water inlet. When the filter bottle is separated from the rotating disk, there is no water pressure between the pure water outlet and the pure water inlet. The water flow at the pure water outlet will not flow to the pure water inlet under the action of the second check valve. In this way, after the filter bottle is removed, the water flow connected to the water channel will not flow out.

[0024] Furthermore, the filter bottle is provided with a raised ring 25 on the outer periphery of its water outlet, and the rotating disk can be positioned within the raised ring. The rotating disk is provided with intermittently spaced bumps 36 on its outer periphery, and the inner circumferential wall of the raised ring is provided with protrusions 26. The protrusions can engage with the protrusions to enable the filter bottle and the rotating disk to rotate together relative to the waterway, thereby enabling the filter bottle to drive the rotating disk to rotate. An arcuate groove 37 is formed between adjacent protrusions. When the protrusions can rotate within the arcuate groove, the filter bottle can rotate relative to the rotating disk and the waterway. In other words, the filter bottle rotates idly (or rotates on its own), and only rotates with the rotating disk when the raised blocks and protrusions engage.

[0025] Specifically, the present invention can include a first rotating disk 41 and a second rotating disk 42 (the aforementioned part of the rotating disk), which can rotate and separate synchronously. The second rotating disk can be separated from the filter element. The second rotating disk is connected to the water channel, but can rotate relatively. The first rotating disk can be connected to the filter element, but can rotate relatively. The outer contours of the two are similar. For details, please refer to the drawings in the specification. The first rotating disk is connected to the filter bottle through a sealing ring. There are semicircular arc structures on both sides of the sealing ring. When the filter bottle is disassembled, the first rotating disk and the filter bottle are rotated at a certain angle. The outer semicircular arc sealing structure can disconnect the water outlets on both sides and make them disconnected. The pure water channel in the middle is stopped by the first check valve, and the water inside the filter bottle will not flow out. The second rotating disk is also connected to the water channel through a sealing ring. There are semicircular arc structures on both sides of the sealing ring. When the filter bottle is removed, the second rotating disk and the water channel rotate at a certain angle. The outer semicircular arc sealing structure can disconnect the water outlets on both sides. The middle pure water channel is stopped by the second check valve, and the water inside the RO machine will not flow out through the water channel. The pushing block is set at the second rotating disk, and the first rotating disk and the second rotating disk are connected by plugging. Please refer to the attached figure for details. (1) When the filter bottle is installed in place, the raw water flow, waste water flow and pure water flow are in a connected state. The two check valves on the pure water flow are respectively located on the filter bottle and the rotating disk (or waterway). The passage direction of the second check valve is the water flow direction, and the passage direction of the first check valve is the reverse water flow direction. The first check valve is abutted by the push block to make the water path conductive; (2) When the filter bottle is disassembled, the raw water flow and the waste water flow are staggered, and the push block is separated from the first check valve. In this way, the two check valves can prevent the pure water flow from flowing out, and the raw water flow and the waste water flow are respectively sealed by the semicircular arc structure of the sealing ring; wherein the sealing ring is a special-shaped structure. At the same time, the water channel is also connected to the first fixed seat 51, and the filter bottle can cooperate with the first fixed seat to achieve connection with the water channel. The second rotating disk is connected to the water channel through the first fixed seat, and the first rotating disk is connected to the filter bottle through the second fixed seat 52. The second fixed seat is fixedly connected to the filter bottle, and the pure water channel is on the axis of rotation of the filter bottle. It is similar to the existing technology and will not be elaborated here.

As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge of the relevant art.
