[0039] Specifically, the outer diameter of mounting portion 110 gradually increases from bottom to top, that is, the gradually changing structure of big up and small down, the opening of filter material mounting position of the set caliber range can be matched, and elastic abutting member 120 can eliminate the gap formed by the original mounting structure at the opening of filter material mounting position, so that the filter element assembly can meet the requirement of separation filtering, the adaptation range is wide, the user can conveniently use the water filter kettle, and the cost of use is reduced.

[0040] As Figure 2 Indicated, in some embodiments of the utility model, elastic abutting member 120 is sealing ring, so as to achieve the effect of sealing isolation, and reduce the occurrence of water leakage.

[0041] As Figure 2 , Figure 3As shown in some embodiments of the utility model, the outer periphery of the mounting portion 110 is provided with an annular groove 111 corresponding to the sealing ring to position the sealing ring and reduce the displacement of the sealing ring when the filter element assembly is inserted into the opening of the filter material mounting position, thereby improving reliability.

[0045] In some embodiments of the utility model, the filter material 900 is a finished filter element matching the filter material cavity, which is composed of a set of filter materials and packaged into a shape matching the filter material cavity to achieve a set of filtering effect and facilitate use.

[0046] It can be understood that in some embodiments of the utility model, the filter material 900 can also be a combination of bulk filter materials, which can be directly placed into the filter material cavity and covered with the cover body 200 to achieve a set of filtering effect.

[0047] As shown in some embodiments of the utility model, Figure 2 , Figure 3 , Figure 4 the inner wall of the opening of the filter element shell 100 is provided with a limiting strip 130 extending in the circumferential direction, and the cover body 200 is provided with a downward extension 210 capable of being placed into the opening of the filter element shell 100, and the outer peripheral wall of the downward extension 210 is provided with a clamping groove 211 extending in the circumferential direction, and one side of the clamping groove 211 is provided with a rotating inlet capable of rotating the limiting strip 130 into the clamping groove 211, so that the cover body 200 can be rotated and fitted into the opening of the filter element shell 100 to realize the detachable assembly of the cover body 200 and the filter element shell 100.

[0048] As shown in some embodiments of the utility model, Figure 2 , Figure 4 the limiting strip 130 is provided with a positioning groove 131, and the clamping groove 211 is provided with a clamping protrusion 212 corresponding to the positioning groove 131, and when the limiting strip 130 is rotated and clamped into the clamping groove 211 at a set position, the clamping protrusion 212 is clamped into the positioning groove 131, so that the cover body 200 is not easily reversed, thereby improving the stability of the assembly of the cover body 200 and the filter element shell 100.

[0049] As Figure 2 , Figure 4 illustrated, in some embodiments of the utility model, the outer peripheral wall of lower extension part 210 is provided with boss 213, clamping groove 211 is established in boss 213, at least two limit strips 130 are distributed along the inner wall of filter core shell 100 and are spaced apart in the circumferential direction, the space for allowing boss 213 to enter is formed between adjacent limit strips 130, so that clamping groove 211 can be in the corresponding position with limit strip 130, and the requirement of rotary clamping is met.

[0050] It can be understood that, in some embodiments of the utility model, clamping groove 211 and limit strip 130 can be inclined structure or spiral structure, which can also meet the requirement of rotary installation.

[0051] It can be conceived that, in some embodiments of the utility model, cover body 200 and filter core shell 100 can also be detachably connected through a buckle mechanism, which is not described in detail here.

[0052] As Figure 1 , Figure 2 , Figure 3 illustrated, in some embodiments of the utility model, cover body 200 is an upwardly convex arched structure, water passing hole 201 of cover body 200 extends from inside to outside, and water passing hole 201 is configured as multiple and spaced apart along the circumferential direction of cover body 200, so as to increase the water passing area, increase the water inflow, and improve the filtering efficiency.

[0053] As Figure 3 illustrated, in some embodiments of the utility model, a matching part 140 is arranged above the mounting part 110, the outer peripheral surface of the matching part 140 is a rotary surface structure, and the outer edge of the cross section of the matching part 140 is a straight line, that is, the outer peripheral surface of the matching part 140 is a barrel surface, so as to improve the matching degree of the opening of the filter material mounting position and the filter core assembly.

[0054] Specifically, as Figure 3 , Figure 6 illustrated, the opening of the filter material mounting position generally extends downward by a certain distance, and the clamping structure at the opening of the traditional filter material mounting position is located at the middle or left and right positions of the opening of the filter material mounting position. If the mounting part 110 is always enlarged upward, it will cause the mounting part 110 to directly abut against the uppermost edge of the opening of the filter material mounting position, causing the filter core assembly to protrude in the kettle or not to be compactly matched, and the use effect is poor. In the utility model, the matching part 140 is arranged above the mounting part 110, which will not affect the normal installation of the mounting part 110, so that the mounting part 110 can enter the set matching position to achieve the effect of set sealing installation, and at the same time, the protrusion of the filter core assembly in the kettle is reduced, and the matching part 140 can be matched or gap matched with the inner wall of the opening of the filter material mounting position, so as to reduce the occurrence of lateral deviation of the filter core assembly or reduce the amplitude of lateral deviation.

[0055] In some embodiments of this utility model, a mating part 140 is provided above the mounting part 110. The outer peripheral surface of the mating part 140 is a rotating surface structure. The outer edge of the cross section of the mating part 140 is a diagonal line. The diagonal line extends from bottom to top and tilts outward to form a structure similar to an inverted frustum. The angle between the diagonal line and the vertical line is less than 5°, that is, the tilt angle of the frustum is less than 5°. The tilt amplitude is small, which can reduce the gap between the mating part 140 and the inner wall of the opening of the filter material mounting position.

[0056] Specifically, the main body of the water filter pitcher and the filter cartridge shell 100 are generally made of plastic, which has a certain elastic deformation capability and a small angle range, so that the mating part 140 can easily enter the opening of the filter media installation position even when tightly fitted, achieving the effect of tight fit.

[0057] like Figure 3 As shown, in some embodiments of this utility model, the outer peripheral surface of the mounting part 110 is a rotating surface structure, and the outer edge of the cross-section of the mounting part 110 is a curved structure. The curvature of the curved structure gradually decreases from bottom to top, that is, the degree of bending of the outer peripheral surface of the mounting part 110 gradually decreases from bottom to top, so that the upper part of the mounting part 110 does not expand excessively and affect the normal fit of the elastic abutment member 120.

[0058] Specifically, the curvature of the outer periphery of the mounting part 110 gradually decreases from bottom to top, eventually smoothly transitioning to the mating part 140, which has a cylindrical or inverted frustum structure. The mounting part 110 and the mating part 140 together form an installation mating structure with an opening at the filter media mounting position, making the filter element assembly stable and reliable to install and adaptable to various sizes of water filter pitchers.

[0059] Reference Figure 5 and Figure 6 The water filter pitcher according to the second aspect of the present invention includes the filter element assembly of any of the first aspects of the present invention, which can realize the water filtration function, and has low consumable cost and high versatility.

[0060] Specifically, the water filter pitcher includes a raw water chamber 901 and a purified water chamber 902. The opening of the filter media mounting position is located between the raw water chamber 901 and the purified water chamber 902. The side wall 903 of the opening of the filter media mounting position forms an installation mating structure with the mating part 140. The elastic abutment member 120 ensures the sealing performance of the opening of the filter media mounting position and reduces the occurrence of water leakage.

[0061] Of course, this invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
