Description

Technical Field

[0001] This application relates to the field of filtration equipment technology, and in particular to a water separator, filter element and drinking water purification equipment. Background Technology

[0002] With the continuous development of the water purifier industry, people's demands for them are increasing, and small, multifunctional water purifiers are especially popular. As the core component of a water purifier, the filter element has multiple functions, stable performance, and a long service life, meeting the needs of different groups of people.

[0003] The inability to completely drain water and / or air from common filter cartridges can cause instability in the operation of pumps and systems. In addition, during the actual operation of water purifiers, the water-blocking components installed in the filter cartridges face complex and variable working conditions, thus requiring higher pressure resistance. Utility Model Content

[0004] Therefore, it is necessary to provide a water-separating component, filter element, and drinking water purification equipment to address the current problems of incomplete air venting and insufficient pressure resistance in water-separating components within the filter element.

[0005] The first aspect of this application provides a water-proof component, including a pipe, wherein the outer peripheral wall of the pipe is provided with a flow guiding channel, and the outer peripheral wall of the pipe is provided with a flow guiding member, the flow guiding member being arranged along the axial direction of the pipe to form the flow guiding channel, the flow guiding channel being used to guide water and / or air in the filter element to be discharged.

[0006] In one embodiment, the flow channel is arranged axially around the pipe fitting.

[0007] In one embodiment, the pipe fitting includes a first pipe body and a second pipe body, the first pipe body and the second pipe body are coaxially arranged, the first pipe body and the second pipe body are connected, and the diameter of the first pipe body is larger than the diameter of the second pipe body.

[0008] In one embodiment, the flow guide includes a first flow guide and a second flow guide. The first flow guide is disposed on the outer peripheral wall of the first pipe body and arranged along the axial direction of the first pipe body, and the second flow guide is disposed on the outer peripheral wall of the second pipe body and arranged along the axial direction of the second pipe body.

[0009] In one embodiment, the inner peripheral wall of the second tube is provided with reinforcing ribs, which extend along the axial direction of the second tube.

[0010] In one embodiment, at least two reinforcing ribs are provided, and both reinforcing ribs extend axially along the second tube body. The at least two reinforcing ribs are spaced apart circumferentially along the second tube body, and the inner circumferential wall of the second tube body and the two adjacent reinforcing ribs form a wastewater flow channel, which is used to guide the wastewater in the filter element to flow out.

[0011] In one embodiment, the first tube includes a main body and a mounting part. The main body is connected to the second tube, and the mounting part is located at one end of the main body away from the second tube and extends radially along the first tube.

[0012] In one embodiment, the outer peripheral wall of the mounting part is provided with a first sealing groove, which is used to embed a sealing element;

[0013] And / or, the outer peripheral wall of the main body is provided with a second sealing groove at one end away from the second tube body, and the second sealing groove is used to embed a sealing element;

[0014] And / or, both ends of the outer peripheral wall of the second tube are provided with a third sealing groove, which is used to embed a sealing element.

[0015] A second aspect of this application provides a filter element, comprising:

[0016] Casing; and

The flow guides installed on the pipes form flow channels, which are arranged circumferentially along the outer periphery of the pipes. When the water-isolating component is installed inside the filter cartridge, the flow guides installed on the water-isolating component can provide a certain support within the filter cartridge. Furthermore, when water flows into the flow channels, it will compress the water and / or air, forcing the water and / or air inside the filter cartridge to enter the flow channels and move along the path defined by the flow channels until the water and / or air are completely and quickly discharged along the flow channels, thus ensuring the stable operation of the filter cartridge.

[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0027] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] like Figure 1 and Figure 2 As shown, this application provides a water-blocking component 10, which includes a pipe 11 and a flow guide 12. The flow guide 12 is disposed on the outer periphery of the pipe 11, and the flow guide 12 and the pipe 11 together form a flow guide channel 13. The flow guide channel 13 is arranged along the outer periphery of the pipe 11 to guide airflow along the path defined by the flow guide channel 13. Thus, by setting the flow guide channel 13, water and / or air can be discharged more easily and quickly, ensuring the stable operation of the overall structure.

[0030] Specifically, the flow guide 12 is axially arranged on the outer periphery of the pipe 11, meaning that when the flow guide 12 is arranged on the outer periphery, the flow guide 12 is not parallel to the axial direction of the pipe 11. Furthermore, the flow channel 13 formed by it is also axially arranged along the outer periphery of the pipe 11.

[0031] In an optional embodiment, the pipe fitting 11 includes a first pipe body 111 and a second pipe body 112, the first pipe body 111 and the second pipe body 112 being coaxially connected, and the diameter of the first pipe body 111 being larger than the diameter of the second pipe body 112. Thus, the end of the first pipe body 111 connected to the second pipe body 112 narrows from a larger diameter to a smaller diameter, and a filter element 22 is provided in both the first pipe body 111 and the second pipe body 112.

[0032] Specifically, the flow guide 12 includes a first flow guide 121 and a second flow guide 122 that are independent of each other. The first flow guide 121 is disposed on the outer periphery of the first pipe body 111 and arranged along its axial direction, and the second flow guide 122 is disposed on the outer periphery of the second pipe body 112 and arranged along its axial direction. The first flow guide 121 and the second flow guide 122 are arranged independently of each other. Thus, through the arrangement of the first flow guide 121, the first flow guide 121 can independently construct a flow guide channel 13 on the outer periphery of the first pipe body 111, and the second flow guide 122 can independently construct a flow guide channel 13 on the outer periphery of the second pipe body 112. The flow guide channels 13 constructed on the first pipe body 111 and the second pipe body 112 can both guide water and / or air to be discharged along their predetermined paths.

[0033] In an optional embodiment, the inner circumferential wall of the second tube 112 is provided with reinforcing ribs 14, which extend axially along the second tube 112. Simultaneously, the reinforcing ribs 14 are spaced apart circumferentially along the inner circumferential wall of the second tube 112. Therefore, the inner circumferential wall of the second tube 112 is provided with multiple reinforcing ribs 14, and these multiple reinforcing ribs 14 are spaced apart, preferably with equal spacing between them. Thus, the structural strength of the second tube 112 can be improved by the multiple equally spaced reinforcing ribs 14.

[0034] Specifically, a plurality of reinforcing ribs 14 are spaced apart and extend from the inner peripheral wall of the second tube 112 toward the central axis of the second tube 112 to form fixing portions 141. That is, the plurality of reinforcing ribs 14 extend radially along the second tube 112, and the extended portions of each reinforcing rib 14 are consistent, so that when other structural components are installed in the second tube 112 later, the extended fixing portions 141 can abut against the structural components installed in the second tube 112 to achieve fixation.

[0035] More specifically, the two adjacent reinforcing ribs 14 spaced apart and the inner wall of the second tube 112 can form a wastewater flow channel 18 so that the wastewater generated in the filter element 20 can flow out through the wastewater flow channel 18.

[0036] In an optional embodiment, the first tube 111 includes a main body 1111, a first end of which is connected to the second tube 112, and a second end of the main body 1111, away from the second tube 112, extends radially from the first tube 111 to form a mounting portion 1112. The outer diameter of the mounting portion 1112 is larger than the outer diameter of the main body 1111, and the axial length of the mounting portion 1112 is larger than the axial length of the main body 1111.

[0037] Specifically, a first sealing groove 15 is provided on the outer periphery of the mounting part 1112, a second sealing groove 16 is provided at the outer periphery of the main body 1111 away from the second tube 112, and a third sealing groove 17 is provided at both ends of the outer periphery of the second tube 112. Sealing elements can be provided in the first sealing groove 15, the second sealing groove 16, and the third sealing groove 17, and the sealing elements can be components such as sealing rings.

[0038] like Figure 3 As shown, this application embodiment provides a filter element 20, which employs the water-isolating element 10 described in any of the above embodiments. The filter element 20 includes a housing 21, and the water-isolating element 10 is disposed within the housing 21. The water-isolating element 10 disposed within the housing 21 can divide the internal chambers of the housing 21 and form at least a first chamber 211 and a second chamber 212, and filter elements 22 are provided in both the first chamber 211 and the second chamber 212.

[0039] Specifically, the filter element 22 includes at least a first filter element 221 disposed in the first tube 111 and a second filter element 222 disposed in the second tube 112. The first filter element 221 can be a UF membrane (Ultrafiltration Membrane), an NF membrane (Nanofiltration Membrane), or an RO membrane (Reverse Osmosis Membrane). The first filter element 221 can perform fine filtration on the water flowing through it to remove tiny particles, bacteria, viruses, heavy metals, dissolved organic matter, etc.

[0040] The second filter element 222 can be made of post-filter carbon fiber, which is mainly used to improve the taste. The post-filter carbon fiber can be ultra-fine fibrous activated carbon, which has a smaller pore size, a larger specific surface area, and more precise adsorption.

[0041] Specifically, a reverse osmosis end cap is provided between the second filter element 222 installed inside the filter cartridge 20 and the water-isolating element 10. This reverse osmosis end cap is located on the outside of the second filter element 222 and abuts against the water-isolating element 10. Specifically, a fixing portion 141 extending radially from the inner circumferential wall of the second tube body 112 of the water-isolating element 10 abuts against the outer circumferential wall of the reverse osmosis end cap. Thus, by providing the fixing portion 141 of the water-isolating element 10, the installation method of the reverse osmosis end cap and the water-isolating element 10 is transformed into a line-surface contact between the fixing portion 141 and the reverse osmosis end cap. This installation method reduces the difficulty of installing the reverse osmosis end cap and the water-isolating element 10. Furthermore, when installing the reverse osmosis end cap, both ends of the fixing portion 141 can be set as inclined structures. The inclined structures can guide the installation of the reverse osmosis end cap, thereby facilitating the assembly between the reverse osmosis end cap and the water-isolating element 10.

[0042] In addition, the fixing part 141, the reverse osmosis end cap, and the inner peripheral wall of the second pipe body 112 together form a wastewater flow channel 18. Thus, the water filtered by the first filter element 221, of which pure water flows out from the pure water outlet after passing through the filtration area of ​​the second filter element 222, while wastewater is discharged directly from the wastewater flow channel 18 without passing through the second filter element 222.

[0043] In an optional embodiment, a pre-filter and a pre-filter are further provided between the water-blocking member 10 and the housing 21 of the filter element 20. The pre-filter can be made of pre-filtered PP cotton, and the pre-filter can be made of pre-filtered carbon fiber.

[0044] Specifically, the pre-filter is disposed on the outer circumferential surface of the pipe fitting 11; the pre-filter is disposed between the pre-filter and the second pipe body 112, and the disposed range of the pre-filter is larger than that of the pre-filter. The second guide member 122 is disposed between the second pipe body 112 and the pre-filter, and the first guide member 121 is disposed between the first pipe body 111 and the pre-filter, with a gap remaining between the pre-filter and the housing 21.

[0045] When water enters the filter element 20, the water flows into the RO membrane after being filtered by the pre-filter and the pre-filter in sequence. The water filtered by the RO membrane enters the central tube located in the middle of the RO membrane. The central tube is equipped with a one-way valve, which ensures that the water entering the central tube can only flow in one direction and finally flows out from the outlet.

[0046] Furthermore, during the outflow process, since the water-isolating element 10 inside the filter element 20 is subjected to forces both inside and outside, the first guide element 121 provided on the first tube 111 and the second guide element 122 provided on the second tube 112 of the water-isolating element 10 can provide internal and external support within the filter element 20. Moreover, the flow channel 13 formed by the first guide element 121 and the second guide element 122 allows water entering the filter element 20 to flow into the flow channel 13 during the first use of the filter element 20, squeezing water and / or air into the flow channel 13. The water and / or air entering the flow channel 13 can move along the path defined by the flow channel 13 until all the water and / or air are smoothly and quickly discharged along the flow channel 13, ensuring the stable operation of the filter element 20. Meanwhile, in this embodiment, the first guide member 121 and the second guide member 122 can be spirally arranged on the first tube 111 and the second tube 112, that is, the first guide member 121, the second guide member 122 and the axis direction of the tube 11 are not parallel, so as to ensure that the water-blocking member 10 in the filter element 20 is strengthened.

[0047] More specifically, to facilitate the installation of the pre-filter, the mounting portion 1112 extending radially from the water-tight member 10 serves as a load-bearing structure for fixing one end of the pre-filter. The first sealing groove 15 on the outer periphery of the mounting portion 1112 is sealed to the housing 21 by a sealing member. A sealing ring is provided between the second sealing groove 16 on the outer periphery of the main body 1111, away from the second pipe body 112, and the mounting member of the pre-filter, thereby achieving a seal between the pre-filter and the main body 1111.

[0048] This application provides a water purification device that uses the filter element 20 described in any of the above embodiments, and therefore also has the above advantages.
