Detailed Implementation

[0016] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0017] Reference Figure 1 A composite faucet purification filter module includes a filter body 1 and a water filtration chamber 2. The module is characterized by: a detachable ultrafiltration chamber 3 installed at the water outlet end of the filter body 1; an ultrafiltration membrane 4 installed inside the ultrafiltration chamber 3; a water outlet terminal 5 installed at the end of the ultrafiltration chamber 3 furthest from the filter body 1; the water outlet terminal 5 being detachably connected to the water filtration chamber 2; a water-blocking sealing ring 6 installed on the ultrafiltration chamber 3; and a sealed connection between the water outlet terminal 5 and the end of the water filtration chamber 2. The water filtration chamber 2 is connected to the lower water pipe of the faucet via a three-way pipe 26.

[0018] The purification filter module is installed on one side of the faucet via a three-way pipe 26, making water dispensing more convenient and faster. By using the purification filter module, there is no need to install a water purifier, thus reducing the space occupied. During the installation of the water purification module, the filter body 1 is first installed on the ultrafiltration chamber 3, then the ultrafiltration chamber 3 is connected to the water outlet terminal 5, and then the filter body 1, ultrafiltration chamber 3, and water outlet terminal 5 are inserted into the water filtration chamber 2. At this time, the water-blocking sealing ring 6 installed on the ultrafiltration chamber 3 forms a sealing structure between the outside of the ultrafiltration chamber 3 and the water filtration chamber 2, and the water outlet terminal 5 forms a sealing structure with the end of the water filtration chamber 2. Finally, the water filtration chamber 2 is connected to the water pipe at the bottom of the faucet through the three-way pipe 26, thereby installing the water purification module on the water pipe. Therefore, the assembly and installation of the water purification module is convenient and quick. When the filter element needs to be replaced, the water outlet terminal 5 is removed from the water filtration chamber 2, and the ultrafiltration chamber 3 and filter element body 1 are pulled out to replace the filter element, making filter element replacement more convenient and quick.

[0019] Reference Figure 1, Figure 2 The filter chamber 2 has an inlet 21 at one end and an outlet 22 at the other end near the outlet terminal 5. The outlet 22 is located on the side of the filter chamber 2. A threaded connector 23 is provided at the other end of the filter chamber 2 near the inlet 21. A sealing element 24 (a sealing gasket or a sealing ring) is fitted on the threaded connector 23. The outlet terminal 5 has an outlet hole 51 corresponding to the outlet 22. During the water purification process, the purification filter module enters through the inlet 21, passes through the filter body 1 from the side of the filter body 1, exits from the end of the filter body 1, enters the ultrafiltration chamber 3, is treated by the ultrafiltration membrane 4 installed in the ultrafiltration chamber 3, and then enters the outlet terminal 5. It is then output from the outlet hole 51 of the outlet terminal 5 and discharged from the outlet 22. The ultrafiltration chamber 3 is equipped with a water-blocking sealing ring 6, which forms a sealing structure with the filter chamber 2 to prevent unfiltered water from being discharged from the outlet 22, thereby ensuring the water filtration effect.

[0020] Reference Figure 1 , Figure 3 , Figure 4 The ultrafiltration chamber 3 is provided with a plug hole 31 at one end near the filter element body 1. The filter element body 1 is provided with a water outlet end cap 11 at one end near the ultrafiltration chamber 3 and a water sealing end cap 12 at one end away from the ultrafiltration chamber 3. A water outlet tube 13 is installed on the water outlet end cap 11 and is inserted into the plug hole 31. A plug sealing ring 14 is fitted on the water outlet tube 13. A snap-fit ​​tube 15 is installed at the end of the water outlet end cap 11 near the filter element body 1 and snaps onto the filter element body 1. Multiple support protrusions 16 are fixed on the side of the water sealing end cap 12 away from the filter element body 1. The support protrusions 16 are used to keep the water sealing end cap 12 at a certain distance from the water inlet 21 so that water can enter the filter element body 1 from the side and exit from the water outlet tube 13. When water enters the filter chamber 2 through the inlet 21, it quickly reaches the side of the filter body 1 under the action of the support protrusion 16 and passes through the filter body 1. The outlet end cap 11 is inserted into the filter body 1 through the snap-fit ​​tube 15, which improves the stability of the connection between the filter body 1 and the outlet end cap 11. The outlet end cap 11 is inserted into the insertion hole 31 through the outlet insertion tube 13, and the insertion sealing ring 14 is fitted on the outlet insertion tube 13. This makes it easier and faster to install and disassemble the filter body 1 and the near-ultrafiltration chamber 3, and allows the filtered water to enter the ultrafiltration chamber 3 and be filtered again through the ultrafiltration membrane 4, thereby improving the quality of the filtered water. A water-sealing end cap 12 is installed at the end of the filter element body 1 away from the ultrafiltration chamber 3, which can prevent water from directly entering the interior of the filter element body 1.

[0021] Reference Figure 1 , Figure 4The first connection method between the water outlet terminal 5 and the ultrafiltration chamber 3 is as follows: a limiting groove 52 is provided at one end of the water outlet terminal 5 near the ultrafiltration chamber 3, and a snap-fit ​​protrusion 32 is installed on the side of the ultrafiltration chamber 3 near the water outlet terminal 5, and the snap-fit ​​protrusion 32 snaps into the limiting groove 52.

[0022] The limiting slot 52 has a T-shaped structure. When the locking protrusion 32 is inserted into the limiting slot 52, the ultrafiltration chamber 3 can be rotated to connect the ultrafiltration chamber 3 with the water outlet terminal 5, making the filter module assembly more convenient and quick.

[0023] Reference Figure 1 , Figure 5 The second connection method between the water outlet terminal 5 and the ultrafiltration chamber 3 is as follows: the water outlet terminal 5 and the ultrafiltration chamber 3 are connected by a thread; the ultrafiltration chamber 3 and the water outlet terminal 5 can be connected together by rotating the ultrafiltration chamber 3 or the water outlet terminal 5, which makes the assembly of the filter module more convenient and quick.

[0024] Reference Figure 1 A water valve 25 is installed at the end of the water filtration chamber 2 away from the water outlet 22. The opening and closing of the filter module is controlled by the water valve 25, making the filter module more convenient to use.

[0025] Reference Figure 1 The water valve 25 is installed between the water filter chamber 2 and the three-way pipe 26. The lower end of the three-way pipe 26 is connected to the tap water pipe, the upper end of the three-way pipe 26 is connected to the faucet, and the side pipe of the three-way pipe 26 is connected to the filter module. This allows it to be combined with the faucet we use daily, making water purification more convenient. At the same time, it ensures that the faucet and the filter module can be used independently without affecting each other, thus extending the service life of the filter module.

[0026] Reference Figure 1 A limiting frame 33 is installed on the side of the ultrafiltration chamber 3 away from the outlet terminal 5. The limiting frame 33 is sleeved on the outside of the filter element body 1. The limiting frame 33 can make the connection between the ultrafiltration chamber 3 and the filter element body 1 more stable.

[0027] Reference Figure 1 The water filter chamber 2 has a screw hole 27 at one end near the water outlet terminal 5, and a screw groove 53 is provided on the water outlet terminal 5. An end sealing ring 54 is installed on the lower side of the screw groove 53. When the water outlet terminal 5 is inserted into the water filter chamber 2, the water outlet terminal 5 and the water filter chamber 2 form a sealing structure under the action of the end sealing ring 54. The water outlet terminal 5 is locked to the end of the water filter chamber 2 by a screw passing through the screw hole 27 and connecting to the screw groove 53.
