[0025] like Figures 1-4 As shown, a convenient filter faucet includes a faucet body 1 and a connecting water pipe 2 located at the front end of the faucet body 1. An extension pipe 3 is connected to the connecting water pipe 2. A partition 4 is fixedly connected inside the extension pipe 3. One end of the partition 4 extends into the interior of the connecting water pipe 2 and is fixedly connected to the connecting water pipe 2. The partition 4 divides the extension pipe 3 into an inlet channel and an outlet channel. A mounting base 5 is fixedly connected to the extension pipe 3. The mounting base 5 is provided with an inlet 6 and an outlet 7. The inlet 6 is connected to the inlet channel, and the outlet 7 is connected to the outlet channel. An integrated filter element 8 is installed on the mounting base 5. Water flows from the connecting water pipe 2 into the inlet channel of the extension pipe 3, and through the inlet 6 of the mounting base 5 into the inner tank 9 of the integrated filter element 8. After being filtered by the filter material 11 inside the inner tank 9, it enters the housing 10 through the connecting hole 14, and then flows into the outlet channel of the extension pipe 3 through the outlet 7 of the mounting base 5 via the second connecting pipe 13. Finally, usable purified water flows out from the faucet body 1.

[0026] The integrated filter element 8 includes an inner liner 9 and a housing 10. The inner liner 9 is disposed inside the housing 10, and a filter material 11 is disposed inside the inner liner 9. A first connecting pipe 12 is connected to the inner liner 9, and the first connecting pipe 12 passes through the housing 10 and is connected to the water inlet 6.

[0027] The shell 10 is communicated with a second connecting pipe 13, the second connecting pipe 13 is communicated with the water outlet 7, the inner container 9 is provided with a communication hole 14, and the inner container 9 is communicated with the shell 10 through the communication hole 14.

[0028] The connecting water pipe 2 is fixedly connected with a fixed hoop 15, the fixed hoop 15 is fixedly connected with a baffle 16, the baffle 16 is penetrated through with a pressing rod 17, the bottom end of the pressing rod 17 is fixedly connected with a cover plate 18, the cover plate 18 is located above the mounting seat 5, and the cover plate 18 is coincident with the axis of the mounting seat 5.

[0029] The pressing rod 17 is sleeved with a first spring 19, the first spring 19 is located between the baffle 16 and the cover plate 18, and the first spring 19 is used to exert a pre-tightening force for the cover plate 18 to move away from the baffle 16.

[0030] The water inlet 6 and the water outlet 7 are provided with a support 20 inside, the support 20 is fixedly connected with a connecting rod 21 inside, the connecting rod 21 is fixedly connected with a limiting plate 22 which can cover the end of the water inlet 6 or the water outlet 7, the connecting rod 21 is sleeved with a second spring 23, and the second spring 23 is used to exert a pre-tightening force for the limiting plate 22 to move close to the support 20. In the process of installing the filter core, when the filter core is not completely installed in place, the limiting plate 22 will partially block the water inlet 6 or the water outlet 7 under the action of the second spring 23, so as to limit the water flow. When the filter core is installed in place, the filter core will push the limiting plate 22 to overcome the elastic force of the second spring 23, so that the water flow can pass normally, thereby ensuring the correctness and sealing performance of the installation of the filter core.

[0031] In order to enhance the sealing effect, sealing rings and sealing pads can be arranged at the ends of the water inlet 6 and the water outlet 7, so as to avoid water leakage.

[0032] Working principle:

[0033] In normal use, the water flow enters the water inlet channel of the connecting water pipe 2, enters the inner container 9 of the integrated filter core 8 through the water inlet 6 of the mounting seat 5, and then enters the shell 10 through the communication hole 14 after being filtered by the filter material 11 in the inner container 9. Finally, the water flow flows into the water outlet channel of the extension pipe 3 through the second connecting pipe 13 and the water outlet 7 of the mounting seat 5, and then flows out of the faucet body 1 to become purified water for use.

[0034] When the filter core needs to be replaced, the pressing rod 17 is pulled upward to overcome the elastic force of the first spring 19, so that the cover plate 18 is away from the mounting seat 5. At this time, the old integrated filter core 8 can be taken out from the mounting seat 5. The new integrated filter core 8 is placed on the mounting seat 5 in the correct direction, and the pressing rod 17 is loosened. Under the action of the first spring 19, the cover plate 18 is pressed against the filter core, and the sealing between the filter core and the mounting seat 5 is ensured. During the installation of the filter core, when the filter core is not completely installed in place, the limiting plate 22 will partially block the water inlet 6 or the water outlet 7 under the action of the second spring 23, and the water flow is limited. When the filter core is installed in place, the filter core will push the limiting plate 22 to overcome the elastic force of the second spring 23, so that the water flow can pass normally, thereby ensuring the correctness and sealing of the installation of the filter core, and realizing the convenient, fast and reliable replacement of the filter core and the normal filtering function of the faucet.
