Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to a stainless steel ultrafiltration water purifier. Background Art

[0002] A water purifier, also known as a water purifier or water purifier, is a water treatment device that deeply filters and purifies water according to specific usage requirements. Water purifiers generally refer to small purifiers used in homes. They filter water to remove floating debris, heavy metals, bacteria, viruses, residual chlorine, silt, rust, and microorganisms, utilizing high-precision filtration technology.

[0003] After searching, the Chinese patent application number is: CN202110233185.0, which discloses a water purifier, including a shell and a water pump installed in the shell, an integrated water circuit board, and multiple filter elements that can be detachably connected to the integrated water circuit board. The integrated water circuit board is integrally formed with a water inlet pipe for water to be filtered, a first purified water outlet pipe, a pressure barrel connecting pipe, a second purified water outlet pipe with an induction switch connected to one end, a first filter element interface for connecting the first filter element, a second filter element interface for connecting the second filter element, a third filter element interface for connecting the third filter element, and an inlet valve connecting pipe; the water inlet pipe for water to be filtered is connected to the first purified water outlet pipe after being filtered by the first filter element, and one end of the first purified water outlet pipe can be connected to the water inlet end of the second filter element in sequence through the water pump, the inlet valve, and the inlet valve connecting pipe; the invention adopts an integrated water circuit board to achieve convenient layout and connection, save space, and the filter element is quick to disassemble and assemble, firmly connected, and not easy to loosen and leak.

[0004] The above technical solution still has defects. Since there are many micropores on the ultrafiltration membrane, when the flow rate and pressure are high, the ultrafiltration membrane will be compacted and the water resistance will increase, which will reduce the water filtration rate. When the water pressure is high, the suspended matter mixed in the water will quickly impact the ultrafiltration membrane, blocking the micropores, thereby affecting the filtration of the water, and may also burst the plastic water purifier pipes and casing. Therefore, we need to propose a stainless steel ultrafiltration water purifier. Utility Model Content

DETAILED DESCRIPTION

[0023] 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 embodiments described 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 efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] A stainless steel ultrafiltration water purifier comprises a front filter cartridge 1, a rear filter cartridge 3 and a regulating mechanism for regulating water flow;

[0026] The adjustment mechanism includes an adjustment ball 2, an adjustment ring 13 disposed within the inner cavity of the adjustment ball 2, and a stainless steel filter 14 fixed within the adjustment ring 13. A shaft 15 for adjusting the direction of the adjustment ring 13 is integrally formed on one side of the outer wall of the adjustment ring 13. The shaft 15 is rotatably mounted on the outer wall of the adjustment ball 2 via a sealed bearing.

[0027] A first sleeve 16 is mounted on the outer wall of the adjustment ball 2. A shaft 15 is inserted into the interior of the first sleeve 16, and a rotating handle is welded to the end of the shaft 15, extending to the exterior of the first sleeve 16. A second sleeve 18 is mounted on the top outer wall of the first sleeve 16, connecting to the interior of the first sleeve 16. The first and second sleeves 16 and 18 are arranged perpendicularly. A hole with a smaller diameter than the inner diameter of the second sleeve 18 is defined at the top of the second sleeve 18, through which a slide rod 19 slides. A shift block 20 is mounted on the top end of the slide rod 19. A positioning block 21 is positioned within the second sleeve 18, and a compression spring 22 is inserted between the positioning block 21 and the top of the second sleeve 18. The lower end of the slide rod 19 is wedge-shaped. Multiple adjustment slots 17 are formed around the outer wall of the shaft 15, located within the first sleeve 16. The lower end of the slide rod 19 fits snugly into these slots.

[0028] In actual use, the water inlet 4 of the front filter cartridge 1 is connected to the water inlet pipe, and the water outlet 5 of the rear filter cartridge 3 is connected to the water outlet pipe. When the water pressure in the pipeline is too high, the dial block 20 is lifted to make the lower end of the slide rod 19 leave the adjusting groove 17, and the adjusting ring 13 in the adjusting ball 2 is rotated by rotating the handle until the stainless steel filter screen 14 is facing the water flow. At this time, the dial block 20 is released to make the lower end of the slide rod 19 slide into the corresponding adjusting groove 17, and the adjusting ring 13 is positioned. On the one hand, it can divide the pressure and flow of the water flow and reduce the impact force, thereby achieving the purpose of avoiding strong water flow directly contacting the ultrafiltration membrane filter element 8, and on the other hand, it can also play a filtering role.

[0029] Among them, in order to have an intuitive understanding of the water pressure, a water pressure gauge can be installed on the pipeline for real-time monitoring. The water pressure gauge is common knowledge in this field and will not be described here. In addition, in order to be able to adjust the adjustment ring 13 intuitively, the adjustment ball 2 can be set to transparent PVC or transparent tempered glass material to achieve precise adjustment.

[0030] The device has a simple structure and is easy to use. It filters and purifies water through the front and rear filter cartridges 3. The adjustment mechanism can adjust the intensity of the water flow entering the rear filter cartridge 3, which can prevent strong water flow from directly contacting the ultrafiltration membrane and compacting the ultrafiltration membrane to increase resistance, and blocks impurities in the water. During the water filtration process, the contact between impurities and the ultrafiltration membrane is reduced, reducing blockage and thus improving the water filtration rate.

[0033] Both the front filter cartridge 1 and the rear filter cartridge 3 are made of stainless steel. A first fixing ring 11 is provided at the bottom of the front filter cartridge 1 and the top of the rear filter cartridge 3. A second fixing ring 12 is provided at the top and bottom interfaces of the adjusting ball 2. The first and second fixing rings 11, 12 are provided in correspondence with each other and both have holes for installing fixing screws.

[0034] By setting a first fixing ring 11 at the bottom of the front filter cartridge 1 and the top of the rear filter cartridge 3, and setting a second fixing ring 12 at the inlet and outlet on both sides of the adjusting ball 2, the first fixing ring 11 and the second fixing ring 12 are connected by fixing screws, so that the front and rear filter cartridges 3 and the adjusting ball 2 can be quickly and conveniently combined and disassembled for maintenance, which is convenient for installing and replacing the filter element, and also convenient for regular cleaning of the adjusting device in the adjusting ball 2.

[0035] When the first fixing ring 11 and the second fixing ring 12 are assembled, a sealing rubber pad should be placed in the middle to improve the sealing between the front and rear filter cartridges 3 and the regulating ball 2.
