In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0047] In some embodiments of this application, a pre-filter device is provided. Figure 1 This is a structural diagram of a pre-filter device. Figure 2 This is a cross-sectional view of a pre-filter device. Figure 4 An exploded view of a pre-filter device.

[0048] The pre-filter device includes a filter bottle 100. The filter bottle 100 has a cylindrical structure, forming the outer contour of the pre-filter device. A cavity is formed inside the filter bottle 100. The filter bottle 100 is provided with an inlet 310, a first outlet 320, and a second outlet 330 that communicate with the cavity.

[0049] The pre-filter device also includes a filter element 200. The filter element 200 is disposed within the cavity and is configured to filter the flowing water.

[0050] The pre-filter device also includes a first connector 500. The first connector 500 is connected to the first outlet 320 and is configured to connect to the water purifier via a first pipeline.

[0051] The pre-filter device also includes a second connector 600. The second connector 600 is detachably connected to the inlet 310 and the second outlet 330, and is configured to connect to a faucet via a second pipe.

[0052] The water that needs to be filtered flows into the filter element 200 through the inlet 310 for filtration. Depending on the user's needs, the filtered water can be supplied to the water purifier through the first outlet 320, or it can be supplied to the faucet through the second outlet 330 to provide domestic water for the user.

[0053] The first connector 500 and the second connector 600 are of different sizes so that they can be connected to water pipes of different diameters, including the first pipe and the second pipe mentioned above.

[0054] The second connector 600 is detachably connected to the inlet 310 and the second outlet 330. By replacing the second connector 600 with different sizes, it can be adapted to second pipelines of different sizes, thereby improving the applicability of the product.

[0055] The pre-filter device is equipped with an inlet 310, a first outlet 320, and a second outlet 330. A first connector 500 is installed on the first outlet 320, which connects to the water purifier via a first pipe. Second connectors 600 are installed on the inlet 310 and the second outlet 330. The second connector 600 at the inlet 310 connects to the water faucet via a second pipe, and the second connector 600 at the second outlet 330 connects to the water outlet faucet via a second pipe. Thus, the pre-filter device can be connected to both the water purifier and the faucet simultaneously, meeting the needs of both kitchen and household water purification. Furthermore, the placement of the inlets and connectors on the pre-filter device has minimal impact on its size, making it appropriately sized for placement in an under-sink cabinet, facilitating installation and use in the home.

[0056] In some embodiments of this application, the first connector 500 is a three-way connector. Since existing water purifier connectors are generally three-way connectors, setting the first connector 500 to a three-way connector facilitates direct connection of the first connector 500 to the connector on the water purifier via the first pipeline. For example, the first pipeline is a PE pipe.

[0057] In some embodiments of this application, the first connector 500 is welded and fixed to the first outlet. As mentioned above, the first connector 500 is a three-part connector, which is small in size and has a reliable welding and fixing structure.

[0058] In some embodiments of this application, the second connector 600 is a 1 / 4-point connector. Since existing household faucets typically use 1 / 4-point connectors, designing the second connector 600 as a 1 / 4-point connector facilitates direct connection between the second connector 600 and the faucet via a second conduit. For example, the second conduit is a braided flexible hose.

[0059] In some embodiments of this application, the diameter of the first outlet 320 is smaller than the diameter of the inlet 310 and the second outlet 330. As mentioned above, the first outlet 320 is connected to the water purifier via the first connector 500, the second connector 600 is connected to the water inlet faucet in the user's home via the inlet 310, and the second connector 600 is connected to the water outlet faucet in the user's home via the second outlet 330. Since the water purifier has a small water demand and the inlet / outlet faucet has a large water demand, the diameter of the first outlet 320 is set to be smaller than the diameter of the inlet 310 and the second outlet 330 to meet the water flow requirements of different water paths.

[0060] In some embodiments of this application, reference is made to Figure 3 and Figure 5 The second connector 600 includes a first section 610 and a second section 620. The first section 610 is inserted into the inlet 310 and the outlet 330, while the second section 620 is located outside the inlet 310 and the outlet 330 for connection to the second pipeline. The plug-in connection method facilitates installation.

[0061] In some embodiments of this application, the second connector section 620 is provided with threads 621, and the second connector section 620 is connected to the second pipeline thread 621. The threaded connection is reliable and easy to assemble and disassemble.

[0062] In some embodiments of this application, a first groove 611 is provided on a section 610 of the second connector, and a sealing ring 630 is provided in the first groove 611. The sealing ring 630 is in contact with the inner wall of the water inlet 310 and the second water outlet 330 to achieve a seal and prevent water leakage.

[0063] The first groove 611 is provided in two or more, and the sealing effect is further improved by increasing the number of sealing rings 630.

[0064] In some embodiments of this application, the pre-filter device further includes a limiting member 700. Figure 6 This is a structural diagram of the limiting component 700. (Refer to...) Figure 1 , Figure 3 as well as Figure 4 The inlet 310 and the second outlet 330 have openings on their walls. The limiting member 700 is configured to insert into the opening to abut against the second connector section 610 to limit the displacement of the second connector 600.

[0065] During installation, first insert the second connector section 610 into the inlet 310 or the second outlet 330, then insert the limiting member 700 into the corresponding opening. The limiting member 700 abuts against the second connector section 610, which limits the second connector 600 and further improves the installation reliability of the second connector 600, preventing the second connector 600 from moving or falling off.

[0066] In some embodiments of this application, the limiting member 700 includes a transverse portion 730, and first extension ribs 710 are respectively provided at opposite ends of the transverse portion 730, with the two first extension ribs 710 arranged opposite to each other. Two first openings 410 are respectively provided on the walls of the inlet 310 and the second outlet 330. A second groove 612 is provided on a section 610 of the second connector, and the first extension ribs 710 are inserted into the corresponding first openings 410 to engage with the second grooves 612.

[0067] The second connector 600 is held and limited by the snap-fit ​​between the two oppositely arranged first extension ribs 710 and the second groove 612, and the limiting function is reliable.

[0068] In some embodiments of this application, the first extension rib 710 is provided with an arc-shaped segment 711, which engages with the second groove 612. The engagement between the arc-shaped segment 711 and the second groove 612 further improves the reliability of the first extension rib 710 in limiting the second joint 600.

[0069] In some embodiments of this application, the limiting member 700 further includes a second extension rib 720, and a second opening 420 is provided on the wall of the inlet 310 and the second outlet 330. The second extension rib 720 is engaged with the second opening 420 to fix the limiting member 700 to the inlet 310 or the second outlet 330, thereby fixing the limiting member 700 and preventing it from falling off.

[0070] For example, two second extension ribs 720 are provided on the transverse portion 730. The two second extension ribs 720 are located between two first extension ribs 710. A buckle 721 is provided on the second extension rib 720, and the buckle 721 is engaged with the second opening 420.

[0071] In some embodiments of this application, the limiting member 700 is made of high-strength engineering plastic, which is easy to process and has low cost.

[0072] In some embodiments of this application, the material of the filter element 200 includes, but is not limited to, PP cotton, carbon rod, carbon fiber, ultrafiltration membrane, etc. Different combinations of filter elements 200 can meet different water filtration needs, and this embodiment does not impose specific limitations.

[0073] In some embodiments of this application, the filter bottle 100 includes a bottle body 110 and a base 120, both of which are made of plastic and are fixedly connected by spin welding technology.

[0074] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0075] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
