[0023] Reference Figure 1 As shown, the detachable composite filter element provided in the embodiments of this utility model includes a filter bottle 100, a filter bottle cap 200, a filter element cap 300, and a cover plate 400, as follows. Figure 2 As shown, the filter bottle cover 200 is installed on the upper end of the filter bottle 100, and the filter bottle cover 200 has a mounting groove 210 and a first water passage pipe 220 located on one side of the mounting groove 210; as Figure 3 As shown, the filter element cover 300 is placed on the mounting groove 210, and a second water passage pipe 310 is formed on the filter element cover 300; as Figure 4 As shown, the cover plate 400 has a first adapter 410 and a second adapter 420. The cover plate 400 and the filter bottle cover 200 are detachably slidably connected. The cover plate 400 can move between a first position and a second position. In the first position, the first adapter 410 is inserted into the first water pipe 220, as shown. Figure 5 As shown, the second adapter 420 is inserted into the second water pipe 310; in the second position, the first adapter 410 is removed from the first water pipe 220, and the second adapter 420 is removed from the second water pipe 310.

[0024] The first adapter 410 and the second adapter 420 are directly mounted on the cover plate 400. When installing the composite filter element, simply install the filter bottle cover 200 on the upper end of the filter bottle 100, place the filter element cover 300 on the mounting groove 210, and then drive the cover plate 400 to slide and connect with the filter bottle cover 200, so that the cover plate 400 moves from the second position to the first position, allowing the first adapter 410 to be inserted into the first water pipe 220 and the second adapter 420 to be inserted into the second water pipe 310. That is, during installation, only the filter element cover 300 needs to be placed and the cover plate 400 needs to be moved, making the installation simple and reducing the labor intensity of workers.

[0025] Since the cover plate 400, the first adapter 410 and the second adapter 420 are integrally formed, the first adapter 410 and the second adapter 420 do not need to be installed in stages, and there is no need to design an alignment anti-foolproof structure and an anti-rotation structure. It also enhances the clamping ability, so that the first adapter 410 is firmly inserted into the first water pipe 220 and the second adapter 420 is firmly inserted into the second water pipe 310.

[0026] Specifically, the first water pipe 220 and the second water pipe 310 are both connected to the inside of the filter bottle 100. The filter bottle 100 is equipped with a reverse osmosis filter element and a pre-filter element. The pre-filter element is installed inside the reverse osmosis filter element. The upper end of the pre-filter element is connected to the filter element cover 300. When the pre-filter element needs to be replaced, the filter element cover 300 is removed from the filter bottle cover 200. The pre-filter element is removed along with the filter element cover 300. After removal, a new pre-filter element is replaced on the filter element cover 300. The new pre-filter element is then inserted into the reverse osmosis filter element. The filter element cover 300 is placed on the mounting groove 210 of the filter bottle cover 200.

[0027] Specifically, such as Figure 7 As shown, both the first adapter 410 and the second adapter 420 include upper and lower extension sections and left and right extension sections. The upper end of the upper and lower extension sections is connected to the left end of the left and right extension sections, and the lower end of the upper and lower extension sections is connected to the external structure. When the cover plate 400 is in the first position, the right end of the left and right extension sections of the first adapter 410 is inserted into the first water pipe 220, and the right end of the left and right extension sections of the second adapter 420 is inserted into the second water pipe 310. Both the upper and lower extension sections of the first adapter 410 and the upper and lower extension sections of the second adapter 420 are connected to the outside.

[0028] Furthermore, such as Figure 3 As shown, both the second water pipe 310 and the first water pipe 220 are located on the upper left side of the filter bottle 100, as... Figure 5 As shown, the cover plate 400 can move approximately relative to the filter bottle cover 200.

[0029] Since the second water pipe 310 and the first water pipe 220 are both located on the left side of the filter bottle 100, and the cover plate 400 can move left and right, when installing or removing the cover plate 400, simply drive the cover plate 400 left and right, and the first adapter 410 can be inserted into the first water pipe 220, and the second adapter 420 can be inserted into the second water pipe 310, or the first adapter 410 can be removed from the first water pipe 220, and the second adapter 420 can be removed from the second water pipe 310, making it convenient to install and remove the cover plate 400.

[0030] Furthermore, such as Figure 6 As shown, the front and rear sides of the cover plate 400 are slidably connected to the filter bottle cover 200, and the middle part of the cover plate 400 is located above the filter element cover 300.

[0031] Since the middle part of the cover plate 400 is located above the filter element cover 300, the middle part of the cover plate 400 can prevent the filter element cover 300 from moving upward, thereby achieving vertical positioning and fixing the filter element cover 300 in the mounting groove 210.

[0032] Furthermore, such as Figure 6 , 7 As shown, the cover plate 400 includes a horizontal plate 430 and two first vertical plates 440 extending in the left and right directions. The upper ends of the two first vertical plates 440 are respectively located on the front and rear sides of the horizontal plate 430. The first adapter 410 and the second adapter 420 are both located on the bottom of the horizontal plate 430. The bottom of the two first vertical plates 440 has a slider 441. like Figure 6 , 8 As shown, the filter bottle cap 200 has a groove 230 corresponding to the position of the slider 441. The left end of the groove 230 has a left opening 231 for the slider 441 to be inserted into or removed from the groove 230. The upper end of the groove 230 has an upper opening 232 for the first vertical plate 440 to move. The slider 441 is slidably connected to the groove 230, and the first vertical plate 440 is located in the upper opening 232.

[0033] The cover plate 400 adopts the above-mentioned configuration, so that the cross-section of the cover plate 400 is similar to an inverted U-shape, which facilitates the sliding connection with the filter bottle cover 200 and facilitates the blocking of the filter element cover 300 from moving upward, thereby achieving the vertical positioning of the filter element cover 300.

[0034] During installation, slider 441 is inserted into slide groove 230 from upper opening 232, and then drive horizontal plate 430 to move to the right. Slider 441 moves along slide groove 230, causing cover plate 400 to move from second position to first position. During the movement of horizontal plate 430, the first adapter 410 is inserted into first water pipe 220 and the second adapter 420 is inserted into second water pipe 310. The reverse is the disassembly of cover plate 400.

[0035] Furthermore, such as Figure 4 As shown, the cover plate 400 also includes a second vertical plate 450 extending in the front-back direction. The second vertical plate 450 is connected to the left end of the horizontal plate 430 and the left ends of the two first vertical plates 440 respectively. The first adapter 410 is fixedly connected to the horizontal plate 430 and the second vertical plate 450 respectively. The second adapter 420 is fixedly connected to the horizontal plate 430 and the second vertical plate 450 respectively.

[0036] The structural strength of the first adapter 410 and the second adapter 420 is enhanced by the provision of a second vertical plate 450.

[0037] Furthermore, such as Figure 2 , 4 As shown, there are two first water pipes 220, which are located on the front and rear sides of the mounting groove 210 respectively. The outer side wall of each of the two first water pipes 220 has a first snap-fit ​​part 221. The filter cover 300 has a second snap-fit ​​part 320 that snaps into the first snap-fit ​​part 221. When the filter cover 300 is placed on the mounting groove 210, the first snap-fit ​​part 221 and the second snap-fit ​​part 320 snap into each other. The filter cover 300 is snapped into place by the first snap-fit ​​part 221 of the first water pipe 220 via the second snap-fit ​​part 320, so as to position the filter cover 300 in the left and right directions.

[0038] Specifically, the second connecting part 320 is provided on the second water pipe 310.

[0039] Furthermore, the first snap-fit ​​part 221 is a groove, and the second snap-fit ​​part 320 is an insert. When installing the filter cover 300, it is only necessary to make the position of the insert correspond to the position of the groove to facilitate the installation of the filter cover 300.

[0040] Furthermore, such as Figure 5 As shown, both the portion of the first adapter 410 inserted into the first water pipe 220 and the portion of the second adapter 420 inserted into the second water pipe 310 are fitted with sealing rings 500.

[0041] By setting a sealing ring 500 to seal the gap between the first adapter 410 and the first water pipe 220 and the gap between the second adapter 420 and the second water pipe 310, the water circuit is guaranteed not to leak when the filter element is working.

[0042] Furthermore, both the portion of the first adapter 410 inserted into the first water pipe 220 and the portion of the second adapter 420 inserted into the second water pipe 310 have steps 411 that facilitate demolding and compression of the sealing ring 500, with the sealing ring 500 located at the steps 411.

[0043] The step 411 facilitates the demolding of the cover plate 400 and the compression of the sealing ring 500, thereby improving the sealing effect.

[0044] Furthermore, such as Figure 1 As shown, the filter bottle cap 200 is provided with a first handle 240, which makes it convenient for users to take out the entire composite filter element through the first handle 240, and the filter element cap 300 is provided with a second handle 330, which makes it convenient for users to take out the pre-filter element through the second handle 330.
