The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

Referring to fig. 1 to 4, an embodiment of the present invention provides a filter element, where the filter element 1 includes a filter shell 11 and a filter material 12, the filter shell 11 has a hollow inner cavity, the inner cavity is filled with the filter material 12, the filter shell 11 is provided with a water outlet and a water inlet communicated with the inner cavity, and the filter shell 11 is provided with a first filter screen 13 covering the water inlet and a second filter screen 14 located at the water outlet. Wherein, the inlet opening can be one, also can be a plurality of. In this embodiment, the inlet opening is a plurality of.

During the use, water carries out the inner chamber that gets into the filter shell 11 by the inlet opening when first filter screen 13 carries out the one-level filtration, carries out the second grade through filter material 12 in the inner chamber again and filters, and water is by the in-process that the delivery port flows, carries out tertiary filtration through second filter screen 14, through triple filtration, improves filtering quality. The filter shell 11 can be filled with filter materials 12, so that the space is fully utilized, and the filtering effect is enhanced; the arrangement of the first filter screen 13 and the second filter screen 14 not only has a filtering effect, but also can block the filter material 12, and prevent the filter material 12 from running off. When cleaning or changing, with whole filter core 1 as an organic whole, need not frequent installation dismantlement filter screen.

The filter shell 11 comprises a cylinder 111 and an end cover 112 which are detachably connected, wherein an opening is arranged at one end of the cylinder 111, the end cover 112 is positioned at the opening, and the end cover 112 covers the opening in a buckling manner. The cylinder 111 and the end cap 112 are detachably connected and provided with an opening, so that the filter material 12 can be conveniently filled into the inner cavity, and the filter material 12 can be conveniently poured out during cleaning or replacement. In the present embodiment, the cylinder 111 is a cylindrical cylinder. Of course, the cylinder 111 may be provided in other shapes according to actual needs, and is not limited herein. The barrel 111 and the end cap 112 may be snap-fit or may be in mating abutment with other components during use.

The water outlet is disposed on the end cap 112. In order to guide the discharged water and facilitate the connection of the filter element 1 with other components, a bulge is arranged on one side of the end cover 112 away from the cylinder 111 and opposite to the water outlet, and a water outlet channel communicated with the water outlet is arranged on the bulge.

A support ring 15 is provided at the end of the cylinder 111 where the opening is located, the support ring 15 abuts against the end face of the cylinder 111, and the second filter 14 is clamped on the inner wall of the support ring 15. The second filter screen 14 is arranged right opposite to the opening, so that the filter effect is achieved, the filter material 12 in the inner cavity is prevented from losing from the opening, and the aperture of the second filter screen 14 is smaller than the minimum diameter of the particles of the filter material 12. The support ring 15 is sandwiched between the cylinder 111 and the end cap 112, and the support ring 15 may be made of rubber material to perform a sealing function.

The cylinder 111 includes a bottom wall opposite to the opening and a side wall vertically connected to the bottom wall, and a water inlet is formed in the side wall in the circumferential direction. Because the first filter screen 13 is arranged, as long as the aperture of the first filter screen 13 is smaller than the minimum diameter of the granular filter material 12, the shape, the extending direction and the size of the water inlet hole can be arranged according to actual needs, and are not limited herein.

The bottom wall of the cylinder 111 can be made into a closed end, a water inlet hole can also be formed in the bottom wall, the first filter screen 13 covers the water inlet hole, and the flow area of water is increased so as to improve the filtering efficiency.

In this embodiment, the first filter screen 13 covers the water inlet hole at the outer side of the cylinder 111, so as to increase the area of the first filter screen 13, and facilitate the installation and detachment of the first filter screen 13. Of course, the first screen 13 may be attached to the inner wall of the cylinder 111, and the filter material 12 may be disposed inside the first screen 13, which is not limited herein. A sealing ring is arranged between the first filter screen 13 and the cylinder 111 to prevent the filter material 12 from flowing out from a gap between the first filter screen 13 and the cylinder 111 through the water inlet hole.

One end of the cylinder 111, which is far away from the end cover 112, is provided with a limiting protrusion along the circumferential direction. When the filter screen is installed, one end of the first filter screen 13 is abutted to the limiting protrusion, and the other end of the first filter screen 13 is abutted to the end cover 112 of the buckle cover at the opening, so that the first filter screen 13 is limited.

Referring to fig. 5 to 9, an embodiment of the present invention further provides a water purifying apparatus, including a housing 2 and the above described filter element 1, where the filter element 1 is located in the housing 2, a water storage cavity is formed between the filter shell 11 and the housing 2, and the housing 2 is provided with a water inlet communicated with the water storage cavity. Water enters the water storage cavity from the water inlet, and is subjected to primary filtration through the first filter screen 13 in the process of entering the inner cavity of the filter shell 11 through the water inlet hole in the filter shell 11.

Filter shell 11 and shell 2 between the interval setting, form the water storage chamber, guarantee water and first filter screen 13 full contact, improve the filter effect. When also setting up the inlet opening on the diapire of barrel 111, make the interval setting between diapire and the shell 2, increase the area of contact of water and first filter screen 13, rivers can get into the inner chamber by the diapire and the lateral wall of barrel 111 simultaneously to improve filtration efficiency.

The shell 2 comprises a main body 21 and a cover body 22 which are detachably connected, the main body 21 is provided with an accommodating cavity, one end of the main body 21 is provided with an opening communicated with the accommodating cavity, the cover body 22 is positioned at the opening, and a water inlet is formed in the cover body 22. The main body 21 and the cover 22 are connected by a screw thread, and a seal ring is arranged between the main body 21 and the cover 22.
