[0036] Referring to Figures 1 to 4 , the present utility model provides a composite filter element, comprising:

[0037] An adapter 10, the adapter 10 includes an insertion section 11 and a connection section 12 connected to each other, and a protrusion 111 is provided on the insertion section 11; and

[0038] A filter element cover 20, the filter element cover 20 includes a cover body 21 and a water passing shell 22, the water passing shell 22 is connected to the cover body 21, an installation groove 221 is provided on the water passing shell 22, an avoidance groove 222 and a limiting groove 223 are provided on the groove wall of the installation groove 221, the avoidance groove 222 and the limiting groove 223 are communicated with each other, and a water passing channel 225 is provided at the bottom of the installation groove 221 for the insertion section 11 to be inserted;

[0039] Wherein, when the protrusion 111 is inserted into the avoidance groove 222, the adapter 10 can rotate so that the protrusion 111 is snapped into the limiting groove 223.

[0040] In the technical solution of the present utility model, the composite filter element includes an adapter 10 and a filter cover 20. The adapter 10 includes an insertion section 11 and a connection section 12 connected to each other. A protrusion 111 is provided on the insertion section 11. The filter cover 20 includes a cover body 21 and a water passing shell 22. The water passing shell 22 is connected to the cover body 21. An installation groove 221 is provided on the water passing shell 22. An avoidance groove 222 and a limit groove 223 are provided on the groove wall of the installation groove 221. The avoidance groove 222 and the limit groove 223 are communicated with each other. A water passing channel 225 is provided at the bottom of the installation groove 221. The water passing channel 225 is for the insertion section 11 to be inserted. When it is necessary to install the adapter 10, only need to align the protrusion 111 with the avoidance groove 222, and then insert the protrusion 111 into the avoidance groove 222. At this time, the insertion section 11 is inserted into the water passing channel 225, and then rotate the adapter 10 to make the protrusion 111 snap into the limit groove 223, so as to realize the installation of the adapter 10; when it is necessary to disassemble the adapter 10, the user only needs to rotate the adapter 10 to make the protrusion 111 disengage from the limit groove 223 and be located in the avoidance groove 222, and then pull it out; the installation and disassembly process of the entire adapter 10 does not require the assistance of other tools, and the installation process is simple and convenient, thus facilitating the installation and disassembly of the adapter.

[0041] Further, a first clamping portion is provided on the protrusion 111, and a second clamping portion is provided on the groove wall of the limit groove 223. When the protrusion 111 snaps into the limit groove 223, the first clamping portion and the second clamping portion are clamped and matched. That is, after the protrusion 111 is inserted into the avoidance groove 222, then rotate the adapter 10 to make the protrusion 111 snap into the limit groove 223, and then the first clamping portion and the second clamping portion are clamped and matched. It should be noted that the limit groove 223 mainly limits the thickness direction of the protrusion 111, while the first clamping portion and the second clamping portion limit the circumferential direction of the insertion section 11 of the adapter 10, thereby improving the stability and reliability of the installation of the adapter 10 and the water passing shell 22.

[0042] Furthermore, a sealing ring is sleeved on the outer peripheral surface of the insertion section 11. By providing the sealing ring, the sealing connection between the adapter 10 and the water passing channel 225 is realized. When the protrusion 111 snaps into the limit groove 223 and the first clamping portion and the second clamping portion are clamped and matched, the sealing ring can also play a damping role, thereby reducing the possibility of the adapter 10 rotating under non-human force, and further improving the installation strength of the adapter 10.

[0043] Furthermore, the connecting section 12 mainly serves to connect other pipelines. By providing the connecting section 12, it is convenient for the pipeline to communicate with the water passage 225. At the same time, the connecting section 12 and the insertion section 11 are integrally bent, which facilitates the user to rotate the adapter 10 during installation. On the other hand, the bent connecting section 12 and insertion section 11 also limit adjacent two adapters 10 when multiple adapters 10 are arranged side by side, thereby reducing the rotation amplitude of the adapter 10 under non-human force, and further improving the installation stability and reliability of the adapter 10.

[0044] Referring to Figure 7 and Figure 8 , in an embodiment, the groove width of the limiting groove 223 is W1, the width of the protrusion 111 is W2, and 0.1 mm ≤ W1 - W2 ≤ 0.4 mm. It can be understood that if W1 - W2 > 0.4 mm, the gap between the limiting groove 223 and the protrusion 111 will be too large. Although this makes it easy for the protrusion 111 to be stuck in the limiting groove 223 and the first and second clamping portions to be clamped and matched, the too large gap also results in low clamping strength of the first and second clamping portions, thus easily causing the installation of the adapter 10 and the water passing shell 22 to become loose, and further reducing the installation stability of the adapter 10. If W1 - W2 < 0.1 mm, it will be difficult for the first clamping portion to be stuck into the second clamping portion when the protrusion 111 is being stuck into the limiting groove 223, thereby increasing the installation difficulty of the adapter 10.

[0045] In an embodiment, the width of the protrusion 111 is W2, and the length of the protrusion 111 along the length direction of the limiting groove 223 is L, and L > W2. It can be understood that the limiting groove 223 mainly serves to limit the width direction of the protrusion 111, so L > W2, which makes the limiting area between the limiting groove 223 and the protrusion 111 larger, and further increases the installation stability and reliability of the adapter 10.

[0046] Referring to Figures 1 to 9 , further, the upper end surface of the protrusion 111 is arc-shaped. By setting the upper end surface of the protrusion 111 to be arc-shaped, the space occupied during the rotation of the protrusion 111 is reduced, and at the same time, it makes the process of the adapter 10 transferring from the avoidance groove 222 to the limiting groove 223 smoother, reducing the interference during the rotation process, and further facilitating the installation and disassembly of the adapter 10.

[0047] In one embodiment, the limiting groove 223 includes two opposite first limiting surfaces 223a and second limiting surfaces 223b. The first limiting surface 223a is flush with the bottom wall of the avoiding groove 222, and the second engaging portion is arranged on the second limiting surface 223b. It can be understood that by arranging the first limiting surface 223a flush with the bottom wall of the avoiding groove 222, the process of the adapter 10 entering the limiting groove 223 from the avoiding groove 222 becomes smoother, which facilitates the installation and disassembly of the adapter 10 and improves the installation efficiency of the adapter 10.

[0048] Specifically, the area of the second limiting surface 223b is S1, and the area of the side of the protrusion 111 facing the second limiting surface 223b is S2, where S1≥S2 / 2. The two sides in the width direction of the protrusion 111 are respectively opposite to the first limiting surface 223a and the second limiting surface 223b. The limiting groove 223 mainly limits the thickness direction of the protrusion 111. Therefore, if S1<S2 / 2, the limiting area between the second limiting surface 223b and the protrusion 111 is too small, which easily causes the adapter 10 to shake, thereby reducing the stability and reliability of the installation of the adapter 10. Therefore, by setting S1≥S2 / 2, even if high-pressure water flow passes through the adapter 10, the second limiting surface 223b can still play a role in limiting the adapter 10, reducing the possibility of the separation of the first engaging portion and the second engaging portion, and improving the stability and reliability of the installation of the adapter 10.

[0049] Specifically, the first engaging portion is a clamping protrusion 224, and the second engaging portion is a clamping groove 112. The clamping protrusion 224 is arranged on the second limiting surface 223b, and the clamping groove 112 is arranged on the side of the protrusion 111 facing the second limiting surface 223b. When installing the adapter 10, the protrusion 111 is inserted into the avoiding groove 222, and then the adapter 10 is rotated to make the protrusion 111 enter the limiting groove 223, and the clamping protrusion 224 is clamped into the clamping groove 112. Of course, in other embodiments, the first engaging portion can also be a hook-type clamping plate, and the second engaging portion is a clamping groove 112. When the protrusion 111 is limited in the limiting groove 223, the hook-type clamping plate is clamped into the clamping groove 112.

[0050] Further, the clamping protrusion 224 extends along the thickness direction of the filter element cover 20, and the clamping protrusion 224 is adapted to the clamping groove 112. It can be understood that the limiting groove 223 mainly plays a role in limiting the width direction of the protrusion 111, while the clamping protrusion 224 and the clamping groove 112 mainly play a role in limiting the circumferential direction of the insertion section 11 of the adapter 10, that is, the clamping protrusion 224 and the clamping groove 112 mainly limit the rotation direction of the adapter 10. Therefore, the clamping protrusion 224 is extended along the thickness direction of the filter element cover 20, so as to increase the limiting and fixing effect of the clamping protrusion 224 and the clamping groove 112, thereby increasing the fixing effect between the adapter 10 and the filter element cover 20, and further increasing the stability and reliability of the installation of the adapter 10.

[0051] Further, the side of the clamping protrusion 224 facing the clamping groove 112 is arc-shaped. On the one hand, the upper end surface of the clamping protrusion 224 is arc-shaped, which reduces the rotation space during the rotation installation of the clamping protrusion 224, and thus is beneficial to the miniaturization of the water passing shell 22. On the other hand, the arc-shaped clamping protrusion 224 reduces the interference between the clamping protrusion 224 and the groove wall of the avoidance groove 222 and the groove wall of the limiting groove 223 during the process of the adapter 10 rotating from the avoidance groove 222 to the limiting groove 223, so that the clamping protrusion 224 can be more easily clamped into the clamping groove 112, thereby facilitating the installation of the adapter 10 and improving the installation efficiency of the adapter 10.

[0052] In an embodiment, the composite filter element includes a pre-filter element and a post-filter element, the water purification device includes a reverse osmosis membrane, and the water passing channel 225 includes a reverse osmosis water inlet channel, a sewage discharge channel, a pre-filter water inlet channel, a pre-filter water outlet channel, and a post-filter water outlet channel. Among them, a reverse osmosis water inlet channel, a sewage discharge channel, a pre-filter water inlet channel, a pre-filter water outlet channel, and a post-filter water outlet channel are respectively provided with an adapter 10.

[0053] The filter element cover 20 includes a first filter element cover 20 and a second filter element cover 20. The first filter element and the second filter element are respectively installed on the first filter element cover 20 and the second filter element cover 20, and are respectively located in the first filter cavity and the second filter cavity. The second filter element cover 20 is detachably installed on the first filter element cover 20. The first filter element cover 20 is provided with the reverse osmosis water inlet channel and the sewage discharge channel, and the second filter element cover 20 is provided with the pre-filter water inlet channel, the pre-filter water outlet channel, and the post-filter water outlet channel.

[0054] In the composite filter element, the pre-filter is used to filter impurities such as particulate matter and floccules contained in the water flow. The water flow flows into the pre-filter through the pre-inlet channel for filtration, and then the water filtered by the pre-filter flows out through the pre-outlet channel; the post-filter will further filter the water before it flows out of the water purification device to improve the taste of the water flow, and finally it is discharged through the post-outlet channel. The reverse osmosis membrane mainly uses its characteristics to filter out salt ions in the water. Among them, the water flow flows into the reverse osmosis membrane through the reverse osmosis inlet channel for filtration, and then the salt ions filtered by the reverse osmosis membrane are discharged through the sewage discharge channel.

[0055] The present utility model also proposes a water purification device, which includes a composite filter element. The specific structure of the composite filter element refers to the above-mentioned embodiments. Since this water purification device adopts all the technical solutions of the above-mentioned all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated one by one here. Among them, the water purification device can be a water purifier, a water dispenser with integrated drinking function, a soft and clean integrated machine, a clean and heat integrated machine and other products with water purification function.

[0056] The above is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the technical concept of the present utility model, or direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
