Description

Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to a faucet with multiple filter elements. Background Art

[0002] Faucet is a common name for water valve, which is used to control the size of water flow and has the effect of saving water. At present, when users buy faucets, they usually buy faucets with filter cartridges to ensure safe and healthy water use. However, the filter cartridges in faucets on the market are usually only one type, and there are various types of filter cartridges on the market, such as activated carbon material, ultrafiltration membrane material, KDF filter cartridge, ceramic filter cartridge, ceramic and nano-KDF filter cartridges. The service life and function of different filter cartridges are different, and the application scenarios of each filter cartridge are also different. The service life of different filter cartridges is inconsistent. At present, when users replace the filter cartridge or clean the impurities around the filter cartridge, they need to remove the entire faucet. The whole removal process is cumbersome and inefficient. At the same time, frequent removal of the faucet will reduce the sealing between the faucet and the external water pipe, so that water seepage will occur between the faucet and the water pipe. However, there is a lack of a faucet installed with multiple layers of filter cartridges and the filter cartridges can be quickly disassembled and replaced on the market. Utility Model Content

[0003] In view of the shortcomings of the prior art, the utility model provides a multi-filter faucet to solve the problem that the faucet in the prior art has only a single filter element and the filter element is difficult to disassemble and replace.

[0004] To achieve the above-mentioned purpose, the utility model provides a multi-filter faucet, including a tube body and a valve core installed at the end of the tube body, the starting end of the tube body is a water outlet end, the tube body is provided with a water outlet groove along its length direction, the water outlet groove is connected to the water outlet end of the tube body and forms a water outlet hole, a filter is provided on the water outlet end of the tube body, a threaded fit is arranged between the outer peripheral wall of the filter and the inner peripheral wall of the water outlet hole, the filter is penetrated by a filter hole connected to the water outlet hole along its height direction, a plurality of notches are provided on the outer peripheral wall of the filter along the height direction of the filter, a filter plate is inserted in each of the notches, each of the filter plates is placed in the filter hole, and the material of each filter plate is not consistent.

[0005] The benefits of adopting the above technical solution are: during the use of the faucet, water will flow into the filter through the tube body, and the filter is equipped with multiple filter plates and the material of each filter plate is inconsistent, so that the water can be discharged after being filtered by different filter plates. The inconsistent filter plate materials in the above technology make the filter plates have different functions. For example, the filter plates can be made of activated carbon materials, ultrafiltration membrane materials, KDF filter elements, ceramic filter elements, ceramics and nano-KDF and other materials. Different purification effects on water are achieved through different materials, thereby improving the cleanliness of water. At the same time, filter plates of different materials can be installed according to different usage scenarios or usage conditions. For example, filter plates of different materials can be installed in different application scenarios such as mines, construction sites, airports, etc., so as to improve the practicality and scope of application of the faucet. At the same time, the filter plate in the above technology can be directly inserted into the notch, and by screwing into the filter, the part of the filter plate exposed from the notch is squeezed by the inner wall of the water outlet and always stays in the notch, thereby improving the stability of the filter plate in the filter and improving the installation efficiency of the filter plate by the user; The setting of the notches and the plurality of filter plates allows the user to replace the height of the different filter plates according to the actual application scenario and usage requirements, that is, the order in which the high-pressure water flows through the filter plates, thereby improving the practicality and scope of application of the present technology; the setting of the threaded cooperation between the filter and the water outlet in the above-mentioned technology improves the efficiency of the disassembly and assembly of the filter, and the cooperation of the filter plate and the notch realizes the efficiency of replacing the filter plate. The setting of the above-mentioned technology improves the overall disassembly and assembly efficiency, and the entire disassembly and assembly process is efficient and simple, thereby improving the assemblability; in the above-mentioned technology, in order to improve the sealing between the outer peripheral wall of the filter and the inner peripheral wall of the water outlet, a waterproof sealing ring can be provided on the top end face of the filter or on the outer peripheral wall of the filter or on the inner peripheral wall of the water outlet. The waterproof sealing ring can be made of an elastic material, so that when the first thread groove and the second thread groove are threadedly matched, the waterproof sealing ring can be expanded and fitted between the outer peripheral wall of the filter and the inner peripheral wall of the water outlet, or the waterproof sealing ring is always buckled on the inner peripheral wall of the water outlet due to its elastic performance, thereby improving the sealing between the water outlet and the filter, thereby avoiding the infiltration of high-pressure water.

[0006] The utility model is further configured as follows: a groove is opened on the inner wall of the filter hole along the height direction of the filter tip, an elastic sheet is embedded in the groove corresponding to each notch position, the radial cross-section of the elastic sheet is arc-shaped and the raised portion of the elastic sheet is arranged toward the notch direction, and the elastic sheet is made of elastic material.

[0007] The advantages of adopting the above technical scheme are as follows: the setting of the elastic sheet in the above technology is used to apply a horizontal force to the filter plate. When the filter is fully inserted into the water outlet, the force will continue to be applied to the filter plate, and the filter plate will apply part of the force to the inner peripheral wall of the water outlet, thereby achieving the abutment of the local outer peripheral wall of the filter plate against the inner peripheral wall of the water outlet, thereby improving the sealing strength between the local outer peripheral wall of the filter plate and the inner peripheral wall of the water outlet, so that the high-pressure water flow will not seep out to the outside from the gap between the local outer peripheral wall of the filter plate and the inner peripheral wall of the water outlet, and at the same time, the setting of the elastic sheet increases the support force on the filter plate, so that the filter plate is partially pressed on the inner peripheral wall of the water outlet, thereby avoiding the filter plate from shaking or shifting when impacted by the high-pressure water flow, resulting in filtration being affected or filtration failing; the setting of the raised portion in the above technology increases the abutment area and force concentration between the elastic sheet and the filter plate, and also increases the torque applied by the deformation of the elastic sheet, thereby increasing the loading force on the filter plate.

[0008] The utility model further arranges: the edge of the filter plate end surface is connected to the outer peripheral wall of the filter plate in a smooth curved surface and forms a first inclined surface, and the inner peripheral wall of the water outlet hole is connected to the bottom wall of the water outlet end of the pipe body in a smooth curved surface and forms a second inclined surface.

[0009] The benefit of adopting the above technical solution is that: the setting of the first inclined surface and the second inclined surface in the above technology is used to move the first inclined surface toward the second inclined surface when the filter is inserted and screwed into the water outlet, until the first inclined surface abuts the second inclined surface. At this time, the second inclined surface will apply a force to the first inclined surface so that the first inclined surface is pushed and drives the filter plate to be inserted into the notch, thereby improving the efficiency of disassembly and assembly of the filter and preventing the filter plate from sliding out due to the influence of the elastic sheet when the filter is installed.

[0010] The utility model is further configured as follows: a first thread groove is provided on the outer peripheral wall of the bottom of the filter tip, and a second thread groove threadably matched with the first thread groove is provided on the inner peripheral wall of the water outlet hole.

[0011] The benefits of adopting the above technical solution are: in the above technology, the filter tip can be quickly disassembled and assembled on the faucet by setting the first thread groove and the second thread groove thread cooperation, thereby improving the efficiency of disassembly and replacement of the filter plate; at the same time, the first thread groove is set at the bottom of the filter tip and the second thread groove is set on the inner wall of the water outlet, so as not to affect the normal excavation of the gap and the normal insertion of the filter plate.

[0012] The utility model is further configured that: sealing pads are arranged on the top and the bottom of the inner wall of the notch, and the sealing pads are made of rubber material.

[0013] The benefit of adopting the above technical solution is that the setting of the sealing gasket in the above technology prevents part of the water flow from leaking to the outside from between the inner wall of the notch and the end face of the filter plate, thereby avoiding the phenomenon that part of the water flow is discharged to the outside without being filtered, thereby improving the sealing strength between the notch and the filter plate through the sealing gasket.

[0014] The utility model is further configured as follows: the plurality of filter plates are respectively the first filter plate, the second filter plate and the third filter plate from the top of the filter tip to the bottom of the filter tip, the first filter plate is an activated carbon filter element, the second filter plate is a PP cotton filter element, and the third filter plate is an ultrafiltration membrane filter element.

[0015] The advantages of adopting the above technical solution are: the first filter plate in the above technology is an activated carbon filter element, which is a filter element with activated carbon as the main raw material. The filtration accuracy of the activated carbon filter element is not as high as that of the PP filter element, but its own advantage is that it has a good adsorption effect on the discoloration and odor in the water, and can also improve the taste of the water quality. Therefore, it is the first filter element layer, that is, the high-pressure water flow first passes through the first filter plate, is filtered by the first filter plate, and then filtered by the second filter plate. The service life of the activated carbon filter element is generally 6-12 months; the second filter plate in the above technology is a PP cotton filter element, which is made of polypropylene ultrafine fiber material, and has three filtration modes: surface, deep, and fine. The pore size of the PP cotton filter element is 0.5 microns-100 microns, which can directly filter impurities larger than the pore size in the liquid, and can be filtered through the second filter plate. Filter a large number of large particles of impurities to ensure the cleanliness of water. Generally, the service life of the PP cotton filter element installed in the filter housing is generally 3-6 months; the third filter plate in the above technology is an ultrafiltration membrane filter element, which is made of hollow fiber silk membrane, and the general filtration accuracy is about 0.01 microns. The ultrafiltration membrane filter element is used as the last layer of filter element to filter small particles of impurities; the setting of the above technology is arranged through different filter plate functions to improve the filtering effect and cleanliness of water. At the same time, the third filter plate is set as an ultrafiltration membrane filter element, and the second filter plate is set as a PP cotton filter element. This is to avoid large particles of impurities in the water from being directly filtered through the third filter plate, which will cause a large number of large particles of impurities to accumulate on the third filter plate, thereby causing the third filter plate to gradually become blocked and reduce the water output. The cleanliness of water is improved through the above reasonable arrangement. BRIEF DESCRIPTION OF THE DRAWINGS
