Preferably, a sealant or a sealing coating layer may be disposed in the first annular sealing groove 410 to further reduce the assembly gap between the first annular sealing groove 410 and the wall of the inner barrel 30, so as to achieve a better sealing effect. Of course, the present invention is not limited thereto, and in other embodiments, the lower end of the inner barrel 30 may be hermetically connected to the separation disc 40 by welding.
When the first filter element 50 is disposed in the inner barrel 30, the lower end surface of the first filter element 50 is in sealing contact with the first mounting surface 40a on the separating disc 40, and since the diameter of the first filter element 50 is smaller than that of the inner barrel 30, the first filter element 50 moves along the first mounting surface 40a and is dislocated, thereby affecting the sealing property between the first filter element 50 and the first mounting surface 40 a. In order to avoid the above problem, in this embodiment, the position of the first filter element 50 on the first mounting surface 40a needs to be limited to prevent the first filter element 50 from moving, wherein the first mounting surface 40a is provided with a first annular flange 420 corresponding to the first filter element 50, an inner side surface of the first annular flange 420 abuts against an outer peripheral surface of the first filter element 50, so that the first filter element 50 is limited by the first annular flange 420, and therefore, the first filter element 50 is not shifted or dislocated, and the sealing performance between the first filter element 50 and the separating disc 40 is ensured.

In order to achieve the above purpose, in this embodiment, it is necessary to communicate the second filter chamber 200 with the second water inlet 130 and the second water outlet 140 of the cartridge connector 10. In the second filter cavity 200, a second water inlet cavity 201 is formed at the outer side of the second filter element 60, a second water outlet cavity 202 is formed inside the second filter cavity 200, a water inlet channel 203 of the second water inlet cavity 201 is formed in a gap between the outer barrel 20 and the inner barrel 30, the second water inlet 130 of the filter element joint 10 is communicated with the water inlet channel 203, an overflow port 440a is formed at a position on the separating disc 40 corresponding to the water inlet channel 203 to guide water flow to the second water inlet cavity 201, the water flow enters the second filter cavity 200 from the outside of the second filter cavity 200 to be filtered and purified, and finally, water in the second water outlet cavity 202 is guided to the second water outlet 140 through a water guide pipe.
In the second filter chamber 200, in order to realize filtration and purification by allowing all the water to pass through the second filter element 60 and prevent the water from flowing from the lower end of the second filter element 60 to the second water outlet chamber 202, in this embodiment, the lower end of the second filter element 60 is also in sealing contact with the bottom wall of the outer tub 20. As a preferred embodiment, a lower end cover 210 is disposed between the lower end of the second filter element 60 and the bottom wall of the outer tub 20, and two ends of the second filter element 60 are respectively and correspondingly attached to the second mounting surface 40b and the lower end cover 210 in a sealing manner, so that the lower end of the second filter element 60 is prevented from being directly attached to the bottom of the outer tub 20, the precision requirement on the bottom wall of the outer tub 20 is reduced, the manufacturing difficulty of the outer tub 20 is reduced, and the production cost is reduced.
It will be appreciated that in the above embodiment, the separating disc 40 is provided with an overflow port to communicate the second water inlet 130 with the second water inlet chamber 201. The flow opening may be formed in various manners, such as by directly forming a through hole in the partition plate 40 or by providing the support protrusion 440. Referring to fig. 4 to 7, a plurality of supporting protrusions 440 are disposed on the outer circumferential surface of the partition plate 40, the supporting protrusions 440 abut against the inner wall of the outer tub 20, and an overflow port is formed between adjacent supporting protrusions 440, such that the overflow port communicates the filter chambers at two sides of the partition plate 40, i.e., communicates the water inlet channel 203 with the second water inlet chamber 201. It should be noted that the supporting protrusion 440 also has a function of fixing the separating tray 40 on the inner wall of the outer tub 20, and one end of the supporting protrusion 440 away from the separating tray 40 abuts against the inner wall of the outer tub 20, so as to fix the separating tray 40 in the outer tub 20. In order to fix the partition plate 40 to the outer tub 20 more stably, the support protrusions 440 are uniformly arranged along the circumferential direction of the partition plate 40, so that the stress applied to the partition plate 40 is more uniform, and the partition plate 40 supports the inner tub 30 better.
Because the outlet water in the second filter element 60 can flow to the second outlet 140 through the water conduit, in order to make the overall structure of the composite filter element 1 more compact, the water conduit preferably passes through the inner barrel 30 in the vertical direction, at this time, the water conduit is a central tube 70, the central tube 70 also passes through the separation disc 40 in the vertical direction in a sealing manner, so as to communicate the internal space of the second filter element 60 with the filter element joint 10, thereby realizing the communication between the second outlet cavity 202 and the second outlet 140, and guiding the filtered and purified water out of the second filter cavity 200. Referring to fig. 4, in the present embodiment, a through hole 460 is formed in the separating disc 40 corresponding to the center tube 70, a third annular flange 450 is arranged on the first mounting surface 40a and/or the second mounting surface 40b around the through hole 460, a second annular seal groove 450a is formed between the third annular flange and the tube wall of the center tube 70, a seal ring 80 is arranged between the inner wall of the first filter element 50 and the tube wall of the center tube 70, and the seal ring 80 is in sealing contact with the groove walls of the center tube 70 and the second annular seal groove 450a, respectively, so that radial and axial sealing of the center tube 70 can be realized.
Referring to fig. 1 and 4, in order to prevent the sealing ring 80 in the second annular sealing groove 450a from moving away from the second annular sealing groove 450a along the axial direction of the central pipe 70, a sealing cover 90 is disposed on a notch of the second annular sealing groove 450a, the sealing cover 90 is disposed corresponding to the central pipe 70 and has an avoiding hole 91, and the sealing cover 90 covers the notch of the second annular sealing groove 450a to ensure reliable operation of the sealing ring 80 and sealing effect.
