It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0038] It can be understood that the terms "first", "second" and the like used in the present application can be used herein to describe various elements, but unless specifically stated, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0039] As Figures 1-3 shown, in one embodiment, a filter structure is provided, which comprises:

[0040] a shell 100,

[0041] a water inlet connecting piece 200 installed at the water inlet end of the shell 100;

[0042] a water outlet connecting piece 300 installed at the water outlet end of the shell 100; the water inlet connecting piece 200 and / or the water outlet connecting piece 300 is detachably connected at one end of the shell 100;

[0043] The filter element 400 is arranged in the shell 100 and is mounted between the water inlet connector 200 and the water outlet connector 300.

[0044] In the embodiment, the shell 100 is the outer shell of a pull-out faucet, which is not necessarily in the shape of a cylindrical tube, but can also be in the shape of a square tube or other shapes, as long as the requirements of water inlet and water outlet are met, and can be regarded as the shell 100 of the embodiment. At least one of the water inlet connector 200 and the water outlet connector 300 is detachably mounted on the shell 100, which facilitates the technical personnel to take out and replace the internal filter element 400. The existing pull-out faucet selects to arrange the filter element on the pull-out head, such as the filter pull-out faucet disclosed in CN212941821U. However, the pull-out head itself is movable, which is not convenient for setting a larger volume, and the filtering capacity of the filter structure is limited. Therefore, the embodiment sets a filter structure, the water inlet connector 200 of the filter structure is connected to the valve core structure, and the water outlet connector 300 is connected to the pull-out structure, which is not limited by the specific size of the pull-out head. In addition, the water inlet connector 200 and the water outlet connector 300 of the embodiment are detachable, which facilitates the replacement of the internal filter element 400.

[0045] In the embodiment, the filter element 400 is in the shape of a cylinder, and the two ends of the filter element 400 are respectively mounted on the water inlet connector 200 and the water outlet connector 300. The outer side of the filter element 400 is connected to the first water inlet / outlet port 210 of the water inlet connector 200, and the inner side of the filter element 400 is connected to the second water inlet / outlet port 320 of the water outlet connector 300. The internal flow of the filter element 400 is purified and filtered pure water, and the external flow of the filter element 400 is water flow that has not been filtered. When the water flow penetrates from the outside to the inside, the filtration is completed. This filtration method improves the filtration efficiency and increases the water purification capacity.

[0046] In an optimization scheme, as shown in Figure 4 and 5 the structure of the water inlet connector 200 and the water outlet connector 300 is specifically limited.

[0047] The water inlet connector 200 is provided with:

[0050] The first connecting column 230 is arranged on the side away from the first water inlet / outlet port 210, and the first connecting column 230 is inserted into the inside of the filter element 400.

[0051] The water outlet connector 300 is provided with:

[0052] The second connecting column 310 is arranged on the water outlet connector 300 and is inserted into the inside of the filter core 400.

[0053] The second water inlet and outlet 320 is arranged in the second connecting column 310 and communicates with the inside of the filter core 400.

[0054] In the optimization scheme, generally, the overall filter structure is Figure 1 The water inlet connector 200 is arranged at the bottom of the shell 100, and the positioning plate 220 is used for supporting and positioning the filter core 400. One side of the positioning plate 220 is left with a space for water flow, so that the first water inlet and outlet 210 communicates with the outside of the filter core 400. The filter core 400 is selected as a hollow cylindrical structure, and the first connecting column 230 and the second connecting column 310 are respectively inserted into two ends of the filter core 400, which plays a role of connection and fixation and improves the stability of the installation of the filter core 400.

[0055] In the optimization scheme, a plurality of first grooves 240 are arranged on the first connecting column 230 and the second connecting column 310, and a first sealing ring is arranged in the groove. The first sealing ring seals the inside of the filter core 400. The first sealing ring plays a role of avoiding the direct entry of unfiltered water flow into the inside of the filter core 400 and improving the filtering and purifying effect.

[0057] In the optimization scheme, a plurality of second grooves 340 are arranged on the first connecting column 230 and the second connecting column 310, and a second sealing ring is arranged in the groove. The second sealing ring seals the inside of the shell 100. The second groove 340 and the second sealing ring play a role of sealing the gap between the shell 100 and the connector and avoiding water flow overflow.

[0058] In one optimization scheme, the shell 100 is provided with an observation port 110, and a sealing cylinder 120 is sleeved in the inside of the shell 100 and blocks the observation port 110. The sealing cylinder 120 is selected as a transparent material.

[0059] In the optimization scheme, the sealing cylinder 120 is arranged to facilitate installation, and the transparent observation port 110 can observe the use of the filter core 400, which facilitates the replacement of the filter core 400 in the later period.
