[0002] Ultrafiltration is a device that uses ultrafiltration technology to purify water. The difference from other water purification equipment is that it uses ultrafiltration membrane. The filter element is a commonly used filter element for water purification equipment. It mainly uses ultrafiltration membrane technology to filter and purify water. The ultrafiltration membrane has a specific pore size, usually between 0.001-0.1 microns, which can effectively remove microorganisms, colloids, large molecular organic matter, etc. in the water, while retaining dissolved substances and small molecules in the water.

[0003] The ultrafiltration machine needs to replace the ultrafiltration filter element regularly, which varies according to the use environment, water quality and other factors. Under normal circumstances, the service life of the ultrafiltration filter element is 1-2 years. Therefore, during the 1-2 years, due to the long-term use of the ultrafiltration filter element, the surface of the filter hole will inevitably be stained with dirt with a particle size larger than the filter hole, such as rust and fine particles of sand mixed in the water, causing the filter hole to be blocked. At the same time, fine particles are generated at the position of the filter element, causing the water to have a peculiar smell. At present, when cleaning the ultrafiltration filter element, specialized technicians are required to disassemble and clean the filter element before installing it, which is time-consuming, and if you are not careful during the disassembly and assembly process, the filter membrane may be damaged, causing losses.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1, this embodiment provides an ultrafiltration filter element water purification device, such as Figure 1 As shown, it includes a filtering structure and a packaging shell 2, wherein the packaging shell 2 has a cavity for installing the filtering structure, and the upper end opening of the packaging shell 2 is installed with a sealing cover 1, which can be threaded or bolted into a pre-opened hole of the sealing cover 1 to achieve assembly between the sealing cover 1 and the packaging shell 2. A water supply pipe 11 is arranged on one side of the horizontal end of the fastening sealing cover 1, and the water supply pipe 11 is connected to the tap water pipeline, and a clean water pipe 13 is arranged on the other side, and the clean water pipe 13 is used to discharge the filtered water to meet the user's use needs.

[0025] like Figure 2 , Figure 3 and Figure 4As shown, the filtering structure includes a filter element 1 6 and a filter element 2 5. Water outlet 1 is provided at both upper and lower ends of the filter element 1 6. The clean water pipe 13 is connected with a docking pipe 14 docking with the upper water outlet 1. The upper end of the filter element 2 5 is provided with water outlet 2. The inner diameter of the lower water outlet 1 is larger than the inner diameter of the upper water outlet 1, and the inner diameter of the upper water outlet 1 is larger than the inner diameter of the lower water outlet 2. The filter element 2 5 is sleeved in the filter element 1 6 and the top end of the filter element 2 5 is against the inner top wall of the filter element 1 6. The inner diameter of the upper water outlet 2 is larger than the inner diameter of the upper water outlet 1. In this way, after the top end of the filter element 2 5 is against the inner top wall of the filter element 1 6, the water outlet 1 is located on the inner side of the water outlet 2, and a filtering gap is provided between the filter element 2 5 and the filter element 1 6 to form a secondary filtering structure. After the water pipe 11 injects tap water into the inner cavity of the packaging shell 2, the water passes through the filter element 1 6 for a filtering operation, and then passes through the filter element 2 5 for a secondary filtering operation. The filtered water is discharged from the water outlet 2 at the upper end of the filter element 1 6 to meet the water purification demand.

[0026] The filtration structure also includes a fixed cylinder 3, the top of the outer wall of the fixed cylinder 3 is symmetrically provided with a support block placed on the inner top wall of the packaging shell 2, and the bottom of the outer wall of the filter element 6 is symmetrically fixed with two arc-shaped thread blocks 61 that are threadedly connected to the bottom opening of the fixed cylinder 3. A liquid inlet gap is provided between the filter element 6 and the fixed cylinder 3. The filter element 6 is screwed into the bottom opening of the fixed cylinder 3 by using the thread block 61 to fix the filter element 6 in the fixed cylinder 3. Figure 1 As shown, the inner wall of the encapsulation shell 2 is tilted downward, and the fixed cylinder 3 is seated on the inner tilted side wall of the encapsulation shell 2 by means of a support block, so as to realize stable support for the filter element 6. At the same time, a protrusion 62 is fixed at the bottom end of the outer wall of the threaded block 61, and the protrusion 62 abuts against the side wall of the bottom edge of the fixed cylinder 3. The protrusion 62 is used to facilitate the rotation of the threaded block 61. When the protrusion 62 abuts against the side wall of the bottom end of the fixed cylinder 3, it means that the top wall of the filter element 6 abuts against the inner top wall of the fixed cylinder 3, so that there is no gap between the filter element 6 and the inner top wall of the fixed cylinder 3. The water filtered by the filter element 6 can only be discharged from the opening of the fixed cylinder 3, so as to avoid the water being discharged for use without being filtered.

[0027] Slide the filter element 2 5 downward relative to the filter element 1 6 and adjust the top wall of the filter element 2 5 away from the inner top wall of the filter element 1 6 to form a single-layer filtering structure. The secondary filtering structure and the primary filtering structure are alternately changed to meet the filtering needs, and can be selected according to the use needs. At the same time, when cleaning, slide the filter element 2 5 downward relative to the filter element 1 6, so that the top wall of the filter element 2 5 is away from the inner top wall of the filter element 1 6, and the filter element 2 5 is exposed in the packaging shell 2. At the same time, the clean water pipe 13 is connected to the tap water, and the incoming water pipe 11 changes the passage and docks with the sewer. After the clean water pipe 13 is injected with water, it will reversely inject water into the filter element 1 6, and reversely flush the filter holes of the filter element 1 6 and the filter element 2 5. There is no need for specialized technicians to disassemble and clean the filter element before installing it, avoiding unnecessary time-consuming disassembly and assembly, and avoiding irreversible damage to the filter element caused by disassembly and assembly, resulting in economic losses. The water connected to the incoming water pipe 11 is used to flush the outer wall of the filter element 2 5 and clean the outer wall of the filter element 2 5.

[0028] In addition, an enlarged annular structure is provided at the top of the outer wall of the filter element 2 5, and the outer diameter of the enlarged annular structure is larger than the inner diameter of the lower water outlet 1. The enlarged annular structure can prevent the filter element 2 5 from slipping out of the water outlet 1 at the bottom end of the filter element 1 6, causing the filter structure to be connected with the packaging shell 2 and unable to form a filter structure.

[0029] Furthermore, a diffuser 12 extending along the longitudinal direction inside the encapsulation shell 2 is connected to the water inlet pipe 11, and a strip-shaped water outlet opening is provided on the radial side wall of the diffuser pipe 12. Such a strip-shaped water outlet structure can expand the water supply direction of the injected water, thereby expanding the maximum area of ​​water contacting with the filter element for filtering and improving the filtering efficiency.

[0030] Embodiment 2 is different from embodiment 1 in that Figure 1 and Figure 5As shown, a water outlet 2 can also be provided at the bottom of the filter element 2 5, and the lower water outlet 2 is connected to a waste pipe 4, and the waste pipe 4 is provided with an L-shaped waste channel, one end of which extends to the top wall of the waste pipe 4 and is connected to the lower water outlet, and the other end of which extends to the radial side wall of the waste pipe 4. An extension end 21 extends from the bottom of the packaging shell 2, and a spherical hollow seat 23 is fixed to the inner bottom of the extension end 21, and a valve 22 connected to the spherical hollow seat 23 is connected to the side wall of the extension end 21. The upper and lower ends of the spherical hollow seat 23 are provided with through holes for the waste pipe 4 to pass through, and the bottom wall of the extension end 21 is provided with a threaded hole for the waste pipe 4 to be threadedly connected. The waste pipe 4 is rotated to adjust the position of the filter element 2 5 along the longitudinal direction, so as to change the secondary filtering mechanism and the primary filtering structure. In addition, after adjusting the filter element 2 5 downward from the secondary filtering structure to the primary filtering structure, the bottom opening of the waste discharge channel of the waste discharge pipe 4 is adjusted to the inside of the spherical hollow seat 2323, and a waste discharge channel is formed between the valve 22. The valve 22 is docked with the tap water pipeline, and the tap water is introduced from the valve 22 into the spherical hollow seat 23, and water is injected into the filter element 1 6 and the filter element 2 5 through the waste discharge channel, so as to achieve the purpose of reverse flushing the filter holes of the filter element from the inside to the outside, and unblocking the blocked filter holes. At this time, there is no need to dock the clean water pipe 13 with the tap water pipeline, but it can be directly introduced into the sewer through the water pipe 11. Just close the outlet of the clean water pipe 13, so that the reverse cleaned water will not flow out of the clean water pipe 13.
