Description

Technical Field

[0001] This application belongs to the field of water purifier filters, and particularly relates to a clustered water purification filter element. Background Art

[0002] With the development of social economy and the increasing improvement of people's living quality, people have put forward higher standards for the quality of water used in daily life. Whether it is cooking, washing vegetables or boiling drinking water, it is expected to use a fully purified water source. The common water purification methods in the current market mainly achieve this by filling water purification materials in a specific housing structure. However, there is a significant problem with this traditional method: the contact time between the water flow and the water purification materials is relatively short when the water passes through the housing, which directly affects the water purification effect and is difficult to ensure the comprehensive purification and improvement of water quality. In addition, most water purification devices adopt an integrated filter element design. Although this design simplifies some aspects of installation and maintenance, it also brings inconvenience in replacing the internal purification materials. When the water purification materials in the filter element become ineffective due to adsorption saturation, users often need to replace the entire filter element rather than just the purification materials inside, which not only increases the usage cost but also causes waste of resources due to the frequent replacement of the entire filter element. Thus, the existing technology needs to be further improved. Utility Model Content

[0003] The utility model provides a clustered water purification filter element to solve the problems of short contact time between water flow and water purification materials, limited purification effect, and inconvenient filter element replacement.

[0004] To achieve the above object, the utility model provides the following technical solutions:

[0005] A clustered water purification filter element includes a filter element main body, and an inlet end cap and an outlet end cap detachably installed on both sides of the filter element main body;

[0006] Inside the filter element main body, there are multiple parallel filter element flow channels arranged along the length direction of the filter element main body. The two ends of the filter element flow channels are open to fill purification particles. The inlet end cap is provided with an inlet water pipeline, and the outlet end cap is provided with an outlet water pipeline. The two are respectively blocked on both sides of the filter element main body, so that an inlet water flow channel for guiding water flow to enter, an outlet water flow channel for leading out the purified water flow, and multiple filtering flow channels are formed inside the filter element main body. The multiple filtering flow channels are connected end to end to form a continuous water passing channel. The beginning and end of the water passing channel are respectively connected to the inlet water flow channel and the outlet water flow channel to extend the water flow path and improve the purification effect.

[0007] The clustered water purification filter element of the present application is provided with a plurality of parallel filter element channels arranged along the length direction inside the filter element main body, and purification particles, such as activated carbon, and trace element slow-release particles such as magnesium and calcium, are filled in the filter element channels. When water flows through the inlet channel and enters the plurality of filtering channels connected end to end, it must flow back and forth along the entire length of the filter element main body and only then will it reach the outlet channel after flowing through all the filtering channels. This significantly increases the contact area and contact time between the water flow and the purification particles, thus greatly prolonging the purification process. Due to the extension of the water flow path and the full contact with the purification particles, the clustered water purification filter element can more effectively remove harmful substances such as impurities, residual chlorine, and heavy metals in water, and the water quality purification is more comprehensive and in-depth, meeting people's needs for high-quality drinking water. At the same time, by designing the inlet end cap and the outlet end cap as detachable structures, users can easily open the filter element main body to replace the internal purification particles, which simplifies the maintenance process, reduces the maintenance cost, and improves the user experience.

[0008] In a preferred implementation, side holes for changing the water flow direction are provided at both the head and tail ends of the filtering channels, and the water flow enters from the inlet channel, changes direction through the side holes, flows through all the filtering channels, and then flows out through the outlet channel.

[0009] By providing side holes for changing the water flow direction at both the head and tail ends of the filtering channels, continuous directional changes of the water flow between multiple filtering channels are achieved, which not only prolongs the contact time between the water flow and the purification particles but also increases the complexity and diversity of the water flow path.

[0010] In a preferred implementation, the inlet end cap / outlet end cap is threadedly connected to the filter element main body.

[0011] Tight connection is achieved by rotation. The threaded connection forms a good sealing effect through the tight engagement of multiple turns of threads, effectively preventing water leakage inside or outside the filter element.

[0012] In a preferred implementation, a threaded portion is provided at the bottom of the inlet end cap / outlet end cap, and a screwing operation portion is provided at the top. A plugging sleeve is provided at the center of the screwing operation portion, and the plugging sleeve is communicated with the outlet water pipeline / inlet water pipeline.

[0013] In a preferred implementation, the inlet channel is provided at the center of the filter element main body, and an outwardly convex / inwardly concave interface structure is provided at its water inlet end. An inner groove / outwardly convex portion that matches the interface structure and communicates with the inlet water pipeline is provided on the inlet end cap. When the inlet end cap is installed at one end of the filter element main body, the inlet water pipeline and the inlet water pipe can be closely fitted.

[0014] In a preferred implementation, the water outlet flow channel is arranged near the edge of the filter element body, an outwardly convex conduit is provided at its water outlet end, the water outlet end is provided with an annular diversion groove, the annular diversion groove is communicated with the water outlet pipeline, and when the water outlet end cover is installed at one end of the filter element body, the outwardly convex conduit is located in the annular diversion groove, so that the purified water flows along the annular diversion groove to the water outlet pipeline.

[0015] Due to the matching design of the outwardly convex conduit and the annular diversion groove, users do not need to worry about the corresponding problem between the water outlet flow channel and the water outlet pipeline of the water outlet end cover. When the water outlet end cover is fully screwed in place, the outwardly convex conduit will accurately fit into the annular diversion groove to form a sealed and smooth water flow channel.

[0016] In a preferred implementation, the water outlet pipeline is arranged at the center of the water outlet end cover, and the water outlet end cover is provided with a diversion channel communicating the annular diversion groove and the central water outlet pipeline.

[0017] In a preferred implementation, a silica gel gasket with water outlet holes and water inlet holes is provided between the water inlet end cover / water outlet end cover and the filter element body.

[0018] The silica gel gasket is squeezed between the water inlet end cover / water outlet end cover and the filter element body, and a tight sealing layer is formed by extrusion deformation to prevent water from leaking from these gaps.

[0019] In a preferred implementation, the cross-section of the filter element flow channel is circular, elliptical or fan-shaped. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0030] In the following text, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0031] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. In the present invention, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium.

[0032] In the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral body; it can be directly connected, or indirectly connected through an intermediate medium, and can be the internal communication of two elements or the interaction relationship between two elements. However, indicating a direct connection means that there is no connection relationship constructed through an excessive structure between the two connected main bodies, and only a connection structure is used to connect and form a whole. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0033] In the present utility model, descriptions such as "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0034] The present utility model will be described below in conjunction with the accompanying drawings of the specification.

[0035] The specific solution adopted is as follows:

[0036] As Figure 1-7 shown, the present utility model provides a bundled water purification filter element, which includes a filter element main body 1, and a water inlet end cover 2 and a water outlet end cover 3 detachably installed on both sides of the filter element main body 1;

[0037] Inside the filter element main body, there are multiple parallel filter element flow channels arranged along the length direction of the filter element main body. The two ends of the filter element flow channels are open for filling purification particles. The water inlet end cover 2 is provided with a water inlet pipeline 20, and the water outlet end cover is provided with a water outlet pipeline 30. The two are respectively blocked on both sides of the filter element main body, so as to form an inlet water flow channel 10 for guiding water flow into, an outlet water flow channel 11 for guiding the purified water flow out, and multiple filtering flow channels 12 inside the filter element main body. The multiple filtering flow channels are connected end to end to form a continuous water passing channel. The beginning and end of the water passing channel are respectively communicated with the inlet water flow channel and the outlet water flow channel to extend the water flow path and improve the purification effect.

[0038] In the above structure, by arranging multiple parallel filter element flow channels along the length direction inside the filter element main body, after installing any one end cover, purification particles such as activated carbon and trace element slow-release particles such as magnesium and calcium slow-release particles, which are existing water purification particles, are filled in the filter element flow channels, and then the other end cover is installed. When the water flow enters the multiple filtering flow channels connected end to end through the inlet water flow channel, it must flow back and forth along the entire length of the filter element main body and will reach the outlet water flow channel 11 only after flowing through all the filtering flow channels 12. This significantly increases the contact area and contact time between the water flow and the purification particles, thus greatly extending the purification process; due to the extension of the water flow path and the full contact with the purification particles, the bundled water purification filter element can more effectively remove harmful substances such as impurities, residual chlorine, and heavy metals in the water, and the water quality purification is more comprehensive and in-depth, meeting people's needs for high-quality drinking water. At the same time, by designing the water inlet end cover and the water outlet end cover as detachable structures, users can easily open the filter element main body to replace the internal purification particles, which simplifies the maintenance process, reduces the maintenance cost, and improves the user experience.

[0039] As a preferred embodiment of the present application, refer to Figure 3, side holes 120 for changing the water flow direction are provided at both the head and tail ends of the filtering channel 12. The water flow enters from the inlet water channel, changes direction through the side holes, flows through all the filtering channels, and then flows out through the outlet water channel 11. By providing side holes for changing the water flow direction at both the head and tail ends of the filtering channel, continuous directional changes of the water flow among multiple filtering channels are achieved, which not only prolongs the contact time between the water flow and the purification particles but also increases the complexity and diversity of the water flow path. Specifically, when the water flow enters the filter element from the inlet water channel, it first enters the first filtering channel through the side hole at the head end of the channel. Inside the channel, the water flow comes into full contact with the filled purification particles. Subsequently, when the water flow reaches the side hole at the tail end of the channel, it changes direction and enters the adjacent next filtering channel through the side hole. This process continues continuously among multiple filtering channels until the water flow passes through all the filtering channels and finally flows out through the outlet water channel.

[0040] Due to the complexity and diversity of the water flow path, impurities and pollutants in the water are more fully removed during multiple directional changes and contact processes, thus improving the purification effect of the water quality.

[0041] See Figure 1 and Figure 3 , a complete side hole 120 can be directly opened in the filtering channel, or both ends of each filtering channel are cooperated with the inlet end cap 2 and the outlet end cap 3 through semi-open slots to enclose and form a complete side hole. Compared with directly drilling holes in the partition board, the processing of the semi-open slots is simpler and faster, reducing the production cost.

[0042] See Figure 3 , Figure 4 and Figure 6 , the inlet end cap 2 / outlet end cap 3 is threadedly connected to the filter element body 1. Specifically, the filter element body is provided with internal threads, and the inlet end cap / outlet end cap is provided with external threads. The external threads are matched with the internal threads of the filter element body, and a tight connection is achieved through rotation. The threaded connection forms a good sealing effect through the tight engagement of multiple turns of threads, effectively preventing water leakage inside or outside the filter element.

[0043] Furthermore, the bottom of the inlet end cap / outlet end cap is provided with a threaded portion, and the top is provided with a screwing operation portion 21. A plugging sleeve 22 is provided at the center of the screwing operation portion, and the plugging sleeve is communicated with the outlet water pipe / inlet water pipe.

[0044] In the design of the water purification filter element, the inlet end cap and the outlet end cap adopt a structure with a threaded portion at the bottom and a screwing operation portion at the top, and are equipped with a plugging sleeve. The design of the plugging sleeve allows users to directly insert the external inlet water pipe or outlet water pipe into it for quick connection. Users only need to rotate the screwing operation portion to complete the disassembly and assembly of the end cap and the connection of the inlet and outlet water pipes, without the need for complex tools or cumbersome steps, bringing a more comfortable and efficient use experience to users.

[0045] As a preferred embodiment of the present application, as Figure 2 and Figure 5 , the inlet water flow channel is arranged at the center of the filter element main body, which is conducive to the uniform distribution of water flow to all parts of the filter element. At the water inlet end of the inlet water flow channel, an outwardly convex interface structure 100 can be provided, such as a protruding cylinder, and its surface can be processed with threads. The inlet end cover is designed with an inner groove matching the interface structure of the filter element main body. If the filter element main body adopts an outwardly convex interface, the inlet end cover should be designed with an inner groove; on the contrary, if the filter element main body adopts an inwardly concave interface, the inlet end cover should be designed with an outwardly convex part. The inlet end cover is installed at one end of the filter element main body by rotation. During the rotation process, the inner groove / outer convex part on the inlet end cover is closely matched with the interface structure of the filter element main body to form a sealed connection. When the inlet end cover is completely screwed in place, a tight fit can be achieved between the water inlet pipeline and the inlet water flow channel, ensuring that water does not leak during the transmission process, and the installation is efficient, reliable and easy to operate.

[0046] As a preferred embodiment of the present application, the outlet water flow channel is arranged near the edge of the filter element main body, which helps to optimize the water flow path, ensuring that the water flow enters from the central inlet water flow channel, passes through all the filter flow channels and then reaches the outlet water flow channel. An outwardly convex conduit 110 is provided at the water outlet end, and an annular diversion groove 31 is designed inside the outlet end cover. This groove is connected to the water outlet pipeline and is used to collect the purified water flowing out of the outwardly convex conduit and guide it into the water outlet pipeline. The shape and size of the annular diversion groove should match the outwardly convex conduit to ensure that the outwardly convex conduit can be accurately embedded in the annular diversion groove during installation, forming a tight and smooth water flow channel.

[0047] Similar to the inlet end cover, the outlet end cover is also installed at the other end of the filter element main body by screwing. During the screwing process, due to the matching design of the outwardly convex conduit and the annular diversion groove, users do not need to worry about the corresponding problem between the outlet water flow channel and the water outlet pipeline of the outlet end cover. When the outlet end cover is completely screwed in place, the outwardly convex conduit will be accurately embedded in the annular diversion groove, forming a sealed and smooth water flow channel. At this time, the purified water flow will flow along the annular diversion groove to the water outlet pipeline and finally be discharged from the system.

[0048] Furthermore, the water outlet pipeline is arranged at the center of the outlet end cover. The outlet end cover is provided with a diversion channel 32 connecting the annular diversion groove and the central water outlet pipeline. The water outlet pipeline is arranged at the center position of the outlet end cover, making the processing process simpler. The processing tool can more easily align with the center position for operation, improving the processing accuracy and efficiency. The outlet end cover is also provided with a diversion channel, which starts from a certain or certain positions of the annular diversion groove and gradually extends inwards to the central water outlet pipeline. The design of the central water outlet pipeline makes the outlet end cover present a sense of balance and stability in appearance.

[0049] As a preferred embodiment of the present application, a silica gel gasket 4 with water outlet holes and water inlet holes is provided between the water inlet end cover / the water outlet end cover and the filter element main body. The seal between the water inlet end cover and the water outlet end cover and the filter element main body is crucial. During installation, place the silica gel gasket on the mating surface between the water inlet end cover / the water outlet end cover and the filter element main body. During installation, ensure that the water outlet holes and water inlet holes of the silica gel gasket can accurately align with the interface structures and the outwardly protruding conduits at both ends of the filter element main body respectively. The silica gel gasket is squeezed between the water inlet end cover / the water outlet end cover and the filter element main body, and a tight sealing layer is formed through extrusion deformation to prevent water flow from leaking through these gaps. The silica gel material has good corrosion resistance and can resist the erosion of the chemical substances that may exist in the water to the gasket, ensuring the stability and reliability of long-term use.

[0050] As a preferred embodiment of the present application, the cross-section of the filter element flow channel is circular, elliptical or fan-shaped.

[0051] What is not described in the present utility model can be realized by adopting or referring to the existing technologies.

[0052] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
