The multiple connecting pipes 10 are arranged one-to-one with the multiple filter components. The multiple connecting pipes 10 are respectively connected to the multiple PP cotton cylindrical filter screens 8.

[0022] The bottom of the explosion-proof housing 1 is open and detachably connected to a bottom cover 5. The upper and lower ends of the filter assembly are respectively provided with sealing rubber 91 and bottom seal 92. The sealing rubber 91 has an insertion hole that matches the connecting pipe 10. Furthermore, a sealing ring should be provided on the bottom cover 5 to improve the sealing performance of the connection between the bottom cover 5 and the explosion-proof housing 1. The bottom cover 5 can be made of transparent tempered glass, and the bottom seal 92 can also be made of transparent material. In this way, the user can easily observe the degree of dirtiness inside the PP cotton cylindrical filter screen 8.

[0023] In this technical solution, by setting multiple filter components with smaller diameters, compared with the conventional single large filter element, the combination of multiple activated carbon cylindrical filter screens 7 and multiple PP cotton cylindrical filter screens 8 can increase the filtration area of ​​the water body under the same installation volume, thereby improving the filtration effect of the water body. Furthermore, the maintenance cost of a single small-diameter filter element after damage is lower, resulting in good economic benefits.

[0024] Example 2

[0025] like Figure 1-3 As shown, the filter element and water purification device with it proposed in this embodiment include an explosion-proof housing 1 and multiple sets of filter components.

[0026] An antibacterial layer is provided on the inner wall of the explosion-proof enclosure 1. Specifically, the antibacterial layer can be a silver-based material. Silver has natural antibacterial properties and is often added to plastics, textiles and coatings to inhibit bacterial growth. The upper end of the explosion-proof enclosure 1 is connected to a water inlet shell 2, the water inlet shell 2 is connected to a water inlet pipe connector 3, and the explosion-proof enclosure 1 is connected to a water outlet pipe connector 4.

[0027] Multiple filter components are installed inside the explosion-proof housing 1. The multiple filter components are arranged at equal intervals along the path of a flat spiral. The filter components include PP cotton cylindrical filter screen 8 and activated carbon cylindrical filter screen 7 placed outside the PP cotton cylindrical filter screen 8. The top of the explosion-proof housing 1 is connected to multiple connecting pipes 10 that communicate with the inner cavity of the water inlet housing 2. The multiple connecting pipes 10 are arranged one-to-one with the multiple filter components. The multiple connecting pipes 10 are respectively connected to the multiple PP cotton cylindrical filter screens 8.

[0028] The bottom of the explosion-proof housing 1 is open and detachably connected to a bottom cover 5. The upper and lower ends of the filter assembly are respectively provided with sealing rubber 91 and bottom seal 92. The sealing rubber 91 has an insertion hole that matches the connecting pipe 10. Furthermore, a sealing ring should be provided on the bottom cover 5 to improve the sealing performance of the connection between the bottom cover 5 and the explosion-proof housing 1. The bottom cover 5 can be made of transparent tempered glass, and the bottom seal 92 can also be made of transparent material. In this way, the user can easily observe the degree of dirtiness inside the PP cotton cylindrical filter screen 8.

[0029] Unlike Embodiment 1, this example also includes a water inlet housing 2 located at the upper end of the cylindrical housing 6. A second circular hole 601 penetrating the upper and lower ends of the cylindrical housing 6 is provided in the middle of the cylindrical housing 6. The water inlet pipe connector 3 communicates with the upper end of the second circular hole 601. The inner cavity of the water inlet housing 2 communicates with the lower end of the second circular hole 601. A long piston 11 is movably arranged inside the cylindrical housing 6. Multiple sealing rings 13 are provided on the outer periphery of the long piston 11. Two first circular holes 111 are provided on the long piston 11. Coarse mesh filter screens 12 are installed inside both first circular holes 111. Two cleaning pipes 16 are connected to the cylindrical housing 6. Sealing caps 17 are detachably installed on both cleaning pipes 16. The two... Each end is connected to a push rod 14. The push rods 14 on both sides move through both ends of the cylindrical housing 6 and are connected to push plates 15. In the initial state, the first round hole 111 on one side is connected to the second round hole 601. The coarse mesh 12 can intercept and filter dirt with a larger diameter, which can achieve preliminary treatment of the water and extend the service life of the filter assembly. When cleaning the coarse mesh 12, the push plate 15 pushes the long piston 11 to move, so that the first round hole 111 on the other side is connected to the second round hole 601. Then the corresponding sealing cover 17 is rotated open, so that the coarse mesh 12 can be cleaned without affecting the normal filtration of the water.

[0030] In addition, this technical solution also proposes a water purification device, which includes the above-mentioned filter element.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
