[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Referring to the drawings of the specification, a slow-release filter element structure includes a shell 10, in which a rotatable rotating drum 20 is arranged. During use, the shell and the rotating drum are coaxially arranged, and the rotating drum can rotate relative to the shell. The rotation is mainly formed by the impact of water entering the shell, which will be explained in detail below. A water inlet channel 11 is formed between the inner peripheral wall of the shell and the outer peripheral wall of the rotating drum. A water passage 21 is provided on the side of the rotating drum close to the water outlet end of the shell. Referring to the drawings of the specification, water entering the shell flows upward from the water inlet channel and then flows to the water passage located above the rotating drum; connecting pieces 50 are arranged at intervals on the end surface of the rotating drum located on the side of the water passage, and a water passage is formed between adjacent connecting pieces, and part of the water flow flows from the water passage into the water passage; a first impeller 31 is placed between the connecting pieces, and one end of the connecting shaft 32 of the first impeller extends into the rotating drum and is connected to a rotating drum The first impeller is connected to the rotating blade 33, and the water flowing in from the water passage impacts the first impeller to drive it to rotate, and also drives the rotating shaft and the rotating blade to rotate. The second connecting shaft is provided with a spiral blade 34 located in the water passage, and the water flows into the inner cavity of the rotating cylinder through the spiral blade; a partition 22 is provided in the rotating cylinder, and the partition divides the inner cavity of the rotating cylinder into a first chamber 23 and a second chamber 24 for placing the slow-release material, that is to say: the water flowing in from the water passage first passes through the first chamber, and then enters the second chamber. After the water and the slow-release material are mixed, they return to the original path through the dissolution and diffusion and flow out from the water passage, mix with the original water flow and flow out from the water outlet end of the shell. The first chamber is connected to the water passage, and the partition is provided with a through hole 25 connecting the first chamber and the second chamber. After the above-mentioned rotating blade rotates, the slow-release material dissolved in the entire cavity can be mixed more evenly. In a preferred embodiment, there is a gap between the inner peripheral wall of the water passage and the spiral blade.

[0024] In one embodiment of the present invention, the rotating blade is located in the first chamber and is connected to one end of the connecting shaft. Referring to the figure of the specification, the rotating blade is arranged near the through hole, which can effectively reduce the speed of water flow entering the second chamber and prevent large water flow from directly impacting the slow-release material, causing a large amount of slow-release material to be released.

[0025] In another embodiment of the present invention, one end of the connecting shaft extends into the second chamber, and the rotating blade is located in the second chamber and connected to the connecting shaft. One end of the connecting shaft extends into the second chamber through the through hole. Referring to the drawings of the specification, the rotating blade is located near the through hole in the second chamber, which can effectively prevent the water flow from directly impacting the slow-release material, causing a large amount of slow-release material to be slowly released. At the same time, its rotation can cause the slow-release material at the bottom to be sucked up by the rotating water flow when there is less slow-release material, so that the entire slow-release material can be fully utilized.

[0026] Specifically, the present invention mainly drives the first impeller to rotate by hydraulic power, and water is injected into the first cavity along the spiral blades. The rotating blades below the spiral blades can make the dissolved functional filter material and water mix evenly. In another embodiment above, the rotating blades are inside the second cavity, so that when the filter material with a slow-release function is consumed to a lower position in the cavity, the rotation of the rotating blades can ensure that the filter material at the bottom of the second cavity is completely dissolved and the concentration of the entire cavity is uniform.

[0027] Furthermore, the water inlet end and the water outlet end of the shell are both provided with a convex pin 12, and the two end surfaces of the rotating cylinder are both connected with the convex pin to realize the rotation of the rotating cylinder. The rotating cylinder is provided with a second impeller 26 at one end close to the water inlet end of the shell. When water flows into the water inlet end of the shell, the water flows into the second impeller, causing the rotating cylinder to rotate in the shell.

[0028] In a preferred embodiment of the present invention, the rotating drum further comprises an end cover 27, the lower part of which is connected with a connecting piece, a space 30 is formed between the end cover and the connecting piece, and the first impeller is arranged in the space; a water inlet 35 is formed between two adjacent connecting pieces, and water entering the space from the water inlet impacts the first impeller. A groove 28 is arranged on the top of the end cover to match with the convex pin at the water outlet end of the housing. During use, a groove that can match with the convex pin is also arranged near the water inlet end of the housing of the rotating drum, and the groove is arranged in the middle of the second impeller.

[0029] Referring to the attached drawings of the specification, at least three connecting plates are arranged on one end face of the rotating cylinder, and the connecting plates are distributed in a ring shape on one end face of the rotating cylinder. The figure also shows the water inlet end of the rotating cylinder. The direction of the water flow entering from the water inlet is tangent to the rotation trajectory of the first impeller, which can better drive the first impeller to rotate.

[0030] Furthermore, a convex ring 29 located in the space is provided at the edge of the water passage, and a notch portion 36 cooperating with the convex ring is provided below the first impeller near the connecting shaft.

[0031] The above description shows and describes the preferred embodiments of the present invention. As mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not depart from the spirit and scope of the present invention, and should be within the scope of protection of the claims attached to the present invention.
