It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0025] In Embodiment 1 of the present invention, reference is made to the accompanying drawings. Figures 1-3 A slow-release structure for a static filter element includes a cover 10 and a housing 20 that cooperate with each other. The cover and housing are connected by a threaded connection. An opening is provided at the connection between the housing and the cover, forming a cavity between the cover and the housing. A partition 30 is provided in the cavity, which mainly divides the cavity into two vertically distributed chambers. A first chamber 41 is formed between the partition and the cover, and a second chamber 42 for placing a slow-release block 50 is formed between the partition and the housing. A small hole 11 is provided on the cover to connect the inside and outside of the cavity. Water entering through the small hole contacts the slow-release block to perform slow-release work. A fine hole 31 is provided on the partition to connect the first chamber and the second chamber.

[0026] In this embodiment, a connecting pipe 60 is also provided in the second chamber. The inside of the connecting pipe is connected to the fine hole. Water flowing from the fine hole will flow into the connecting pipe. Preferably, the connecting pipe is also an air pipe. At least one connecting hole 61 is provided on the peripheral wall of the connecting pipe. Preferably, there are three sets of connecting holes, distributed at the two ends and the outer periphery of the middle of the connecting pipe. Two connecting holes are provided at the end of the connecting pipe near the partition. The connecting holes are connected to the inner periphery of the connecting pipe, so that the water flow comes into contact with the slow-release block.

[0027] Furthermore, one end of the connecting tube is fitted to one end face of the partition, and the other end of the connecting tube is open and connected to the second chamber. Referring to the attached drawings, there is a gap 105 between the other end of the connecting tube and the bottom of the shell. In a specific application, the slow-release block is made into an annular shape, thus having a hollow portion, so that the slow-release block can be fitted onto the outer periphery of the connecting tube.

[0028] Furthermore, there is a first gap 101 between the slow-release block and the outer periphery of the connecting tube, and a second gap 102 between one end face of the slow-release block and one end face of the partition.

[0029] In Embodiment 2 of the present invention, reference is made to the accompanying drawings. Figures 4-6 A slow-release structure for a static filter element includes a cover 10 and a housing 20 that cooperate with each other. The cover and housing are connected by a threaded connection. An opening is provided at the connection between the housing and the cover, forming a cavity between the cover and the housing. A partition 30 is provided in the cavity, which mainly divides the cavity into two vertically distributed chambers. A first chamber 41 is formed between the partition and the cover, and a second chamber 42 for placing a slow-release block 50 is formed between the partition and the housing. A small hole 11 is provided on the cover to connect the inside and outside of the cavity. Water entering through the small hole contacts the slow-release block to perform slow-release work. A fine hole 31 is provided on the partition to connect the first chamber and the second chamber.

[0030] In this embodiment, a receiving plate 70 is also provided in the second chamber. One end face of the receiving plate is connected to one end face of the partition via at least one support block 81. Referring to the attached drawings, there can be two support blocks, which can be arranged symmetrically about the pores. The other end plate of the receiving plate is connected to the slow-release block. The receiving plate is mainly used to support the slow-release block from below.

[0031] In a further embodiment, a third gap 103 exists between the outer peripheral edge of the receiving plate and the inner peripheral wall of the second chamber, facilitating contact between the water flow and the slow-release block. A fourth gap 104 exists between the outer peripheral wall of the slow-release block and the inner peripheral wall of the second chamber, also to allow for better contact and engagement between the water flow and the slow-release block. In this invention, after the water flows into the second chamber through the fine holes, it flows from between the receiving plate and the partition to the third and fourth gaps, and then contacts and engages with the slow-release block.

[0032] In this invention, a sealing ring 80 is provided at the connection between the cover and the shell to ensure the product's airtightness. An annular groove 21 is provided on the inner peripheral wall of the shell opening, and the partition plate is connected to the annular groove to separate the first chamber and the second chamber. A protruding ring 32 is provided on the partition plate facing the cover, and the outer peripheral wall of the protruding ring is connected to the inner peripheral wall of the cover.

[0033] This invention can be: 1. By adding a gas-guiding structure to avoid the problem of exhaust, a stable slow-release block (also a filter material) can be achieved; 2. The slow-release block can be of various types, depending on specific needs, and can be vitamin C; 3. The slow-release structure has a shell, a cover, a sealing ring, and a gas-guiding structure. Raw water enters the first chamber between the cover and the partition through small holes on the cover. The gas in the first chamber is forced into the second chamber through fine holes on the partition, or through the connection holes on the air pipe. Subsequently, the raw water enters the second chamber through fine holes on the partition, or through the connection holes on the air pipe, and comes into contact with the slow-release block. The slow-release block begins to dissolve at this point and is released into the raw water under the action of the concentration difference. During the above process, the gas is always above the interior of the second chamber, pressing the filter material downwards, ensuring continuous contact between the filter material and the raw water, thereby ensuring the stability of the removal effect.

[0034] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
