[0035] The present utility model will be further described in detail below with reference to the drawings.

[0036] As Figure 1 shown, a filtering device includes a base 1000 and a filter element 2000, and the base 1000 and the filter element 2000 are detachably connected.

[0037] Please refer to Figure 3 , wherein, the above-mentioned base 1000 includes a main body 100, a water inlet part 200 and a water outlet part 300. An assembly port 11 is provided on the main body 100 for assembling the filter element 2000. An inlet channel (not shown in the figure) and an outlet channel (not shown in the figure) are also opened inside the main body 100 for water to flow through; the water inlet part 200 and the water outlet part 300 are both arranged at the assembly port 11 and connected to the main body 100. In practical applications, the water inlet part 200, the water outlet part 300 and the main body 100 can be molded as one body. The water inlet part 200 and the water outlet part 300 are respectively communicated with the inlet channel and the outlet channel, and the water inlet part 200 and the water outlet part 300 are respectively used to communicate with the water inlet 03 and the water outlet 04 inside the filter element 2000.

[0038] Please refer to Figure 7 , Figure 8, Correspondingly, the above-mentioned filter element 2000 includes a body part 01, an assembly part 02, a water inlet 03, and a water outlet 04. Among them, the assembly part 02 is connected to or integrally formed with the body part 01. The assembly part 02 is used for being assembled on the assembly port 11 of the base 1000. The water inlet 03 and the water outlet 04 are both arranged on the assembly part 02, and the water inlet 03 and the water outlet 04 are respectively used for correspondingly connecting with the water inlet part 200 and the water outlet part 300 of the base 1000.

[0039] In the actual practical process, the water to be purified flows into the main body 100 through the water inlet channel and then flows into the interior of the filter element 2000 through the water inlet 03 of the filter element 2000 from the water inlet part 200 for filtration and purification. The filtered and purified water flows out through the water outlet 04 of the filter element 2000 and enters the water outlet channel inside the main body 100 through the water outlet part 300 of the main body 100. In the above purification process, without the need to additionally set up redundant pipelines, the water can be directly introduced into the filter element 2000 and exported through the base 1000, reducing the consumption of pipelines during the installation process, and thus reducing the production cost.

[0040] In summary, the filter element 2000 is assembled on the assembly port 11 of the base 1000 through the assembly part 02. The water inlet part 200 and the water outlet part 300 arranged on the assembly port 11 are respectively correspondingly connected and communicated with the water inlet 03 and the water outlet 04 arranged on the assembly part 02. Through the above design, the base 1000 only needs to be connected to one part of the filter element 2000 to correspondingly connect the pipelines inside the two, and there is no need to additionally connect redundant pipelines, reducing the consumption of pipelines and also reducing the installation cost.

[0041] In some embodiments, such as Figure 1 , Figure 3 shown, the above-mentioned base 1000 further includes a connector 400. The connector 400 is arranged on the side of the main body 100. The water inlet channel and the water outlet channel are both communicated with the connector 400, and the two connectors 400 are located on the same side of the side of the main body 100, which is convenient for the installation and connection of pipelines during the installation process.

[0042] In some embodiments, at least one annular groove 41 is opened on the side of the above-mentioned connector 400, and a first sealing ring 500 for improving the sealing performance is fitted and sleeved inside the annular groove 41.

[0043] As Figure 3 shown, two annular grooves 41 are opened on the side of the above-mentioned connector 400, and a first sealing ring 500 is fitted and sleeved inside each annular groove 41. The first sealing ring 500 can improve the sealing performance when the connector 400 is used for connecting with a pipeline. The two first sealing rings 500 can make the connection sealing performance between the connector 400 and the pipeline better.

[0044] In some embodiments, such as Figure 2 , Figure 4 shown, the above-mentioned base 1000 further includes a movable member 600. The movable member 600 is arranged between the joint 400 and the main body 100. Both ends of the movable member 600 are respectively connected to the main body 100 and the joint 400. A flow channel is formed inside the movable member 600, and the flow channel is communicated with the water inlet channel or the water outlet channel. The middle part of the movable member 600 can be bent and deflected by a certain angle to change the orientation of the joint 400. With such a design, during the actual installation process, the orientation of the joint 400 can be appropriately and flexibly adjusted according to actual needs, without the need for additional assembly of elbows, greatly improving the adaptability of the joint 400 in pipeline connection, and thus making the pipeline connection simpler and more direct.

[0045] In some embodiments, the above-mentioned movable member 600 includes a locking part and a deflection part 62. The locking part is detachably connected to the main body 100 by means of threads, buckles, etc. One end of the locking part is rotatably connected to one end of the deflection part 62, and the joint 400 is connected to the other end of the deflection part 62, and the deflection part 62 can be bent and deflected.

[0046] Such as Figure 4 shown, one end of the locking member 61 is threadedly connected to the main body 100, and the other end is rotatably connected to the deflection part 62. The end of the deflection part 62 away from the locking member 61 is connected to the joint 400. Through the above design, the movable member 600 can be quickly assembled or disassembled with the main body 100, so as to flexibly operate the movable member 600 during the actual installation process.

[0047] In some embodiments, such as Figure 5 , Figure 6 shown, the water inlet part 200 of the above-mentioned base 1000 is provided with a first end 21, and the water inlet 03 of the above-mentioned filter element 2000 is provided with a first port 031.

The second end 31 is only inserted and mated with the second port 041. Through the above one-to-one corresponding insertion method, it can be ensured that the water inlet part 200 and the water outlet part 300 and the water inlet 03 and the water outlet 04 will not be inserted in the wrong direction when corresponding connections are made, ensuring that the filter element 2000 and the base 1000 can be correctly installed during actual application and assembly.

[0048] In some embodiments, second sealing rings (not shown in the figure) are provided between the water inlet 03 and the water inlet part 200 and between the water outlet 04 and the water outlet part 300. Thereby, the sealing performance of the connection structure between the water inlet 03 and the water inlet part 200 and between the water outlet 04 and the water outlet part 300 can be improved, avoiding the bad situation of water leakage.

[0049] In some embodiments, one of the base 1000 and the filter element 2000 is provided with a positioning post, and the other of the base 1000 and the filter element 2000 is provided with a positioning hole 05, and the positioning post is inserted into the positioning hole 05 correspondingly.
