Description
Technical Field
[0001] This utility model belongs to the field of water dispenser technology, specifically a water dispenser filter element that is not easily clogged. Background Technology
[0002] As a core component ensuring drinking water safety, the filtration efficiency and anti-clogging performance of water dispenser filters directly affect the drinking experience and operating costs. With increasing health awareness among residents, the market is placing higher demands on the filtration precision, lifespan, and ease of maintenance of water dispenser filters.
[0003] In existing technologies, traditional water dispenser filter cartridges mostly use a single filter material or a simple stacked structure. During the filtration process, impurities of different particle sizes in the water, such as sediment, colloids, and rust, easily accumulate and are trapped on the surface of the same filter layer, forming a dense filter cake. This leads to a rapid increase in water flow resistance, causing blockage within a short period. This not only reduces water output efficiency but also requires frequent filter cartridge replacement, increasing user costs. Furthermore, most filter cartridges lack a visually observable internal structure, making it difficult for users to assess the degree of impurity buildup. Users often only replace them after the blockage has become severe, affecting normal use.
[0004] Therefore, this utility model provides a water dispenser filter element that is not easily clogged. Utility Model Content
[0005] To address the shortcomings of existing technologies and solve the problem that traditional water dispenser filter cartridges, as mentioned in the background technology, mostly use a single filter material or a simple stacked structure, impurities of different particle sizes such as mud, colloids, and rust in the water are easily concentrated and intercepted on the same filter layer surface during the filtration process, forming a dense filter cake. This leads to a rapid increase in water flow resistance and blockage in a short period of time, which not only reduces water output efficiency but also requires frequent filter cartridge replacement. Therefore, a water dispenser filter cartridge that is not prone to clogging is proposed.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A water dispenser filter element that is not easily clogged, comprising a shell; a connecting end fixedly installed at the bottom of the shell; a sealing mechanism provided at the top of the shell; an isolation component provided on the inner wall of the shell; a positioning component provided on the inner wall of the shell; and a filter component provided on the inner wall of the inner liner. The sealing mechanism includes a threaded cylinder, a sealing cap, and a sealing ring. The threaded cylinder is fixedly installed at the top of the shell, and the inner wall of the threaded cylinder is threadedly connected to the sealing cap. The sealing cap is located at the top of the shell, and the bottom of the sealing cap is fixedly installed with the sealing ring. The combined use of the threaded cylinder, sealing cap, and sealing ring can fix the inner liner, ensuring high stability during use and preventing leakage, while also facilitating filter element replacement.
[0007] Preferably, the isolation assembly includes an inner liner and an observation window. The inner liner is movably inserted into the inner wall of the outer shell, and the observation window is fixedly installed on both sides of the inner liner surface. In this solution, the use of the inner liner and the observation window allows the user to easily disassemble and replace the filter assembly as a whole, and also allows the user to easily observe the clogging status of the filter assembly from the outside, so as to replace it in a timely manner.
[0008] Preferably, the positioning component includes positioning rods and grooves. Four sets of positioning rods are provided, and the four sets of positioning rods are fixedly installed in a ring on the inner wall of the outer shell. The grooves are opened on the inner liner surface near the positioning rods. The inner liner is slidably installed on the surface of the positioning rods through the grooves. In this design, the cooperation of the positioning rods and grooves can provide positioning and guidance for the inner liner, enabling it to maintain sufficient stability on the inner wall of the outer shell. At the same time, it can also facilitate the alignment of the observation window with the through hole on the surface of the outer shell, so that the user can normally observe the condition of the inner wall of the inner liner.
[0009] Preferably, the filter assembly includes conical blocks and sieve holes. Several sets of conical blocks are provided, and the sets of conical blocks are fixedly installed on the inner wall of the inner tank. The sieve holes are opened on the surface of the conical blocks. In this scheme, the combined use of conical blocks and sieve holes can filter the water source, so that the water source can maintain a high level of cleanliness, thereby improving drinking water quality, reducing the risk of illness, and improving the safety of citizens' drinking water. In addition, the conical design of the conical blocks can guide impurities to the surrounding area, ensuring that the central area remains unobstructed.
[0010] Preferably, several sets of the conical blocks are installed longitudinally on the inner wall of the inner tank, and the diameter of the sieve holes on the surface of each layer of conical blocks gradually decreases from top to bottom. The longitudinal arrangement of multiple sets of conical blocks in this scheme can form a multi-stage filtration technical feature. At the same time, the diameter of each layer of sieve holes is different, which can separate impurities in the water layer by layer, thereby ensuring that impurities do not accumulate in the same filter screen and cause blockage.
[0011] Preferably, the inner liner is made of PPR material. In this solution, PPR material has high corrosion resistance and high temperature resistance, which can prevent the inner liner from corroding due to the accumulation of impurities during use, and also prevent the risk of cracking when transporting hot water.
[0012] The beneficial effects of this utility model are as follows: 1. The water dispenser filter element that is not prone to clogging described in this utility model, through the arrangement of a threaded cylinder, a sealing cap, a sealing ring, an inner liner, and an observation window, allows the inner liner to be fixed in place by the cooperation of the threaded cylinder, the sealing cap, and the sealing ring, thus maintaining high stability during use and preventing leakage. It also facilitates filter element replacement. The cooperation between the inner liner and the observation window allows users to easily disassemble and replace the entire filter assembly, and also allows users to easily observe the clogging status of the filter assembly from the outside, so as to replace it in a timely manner.
[0013] 2. The water dispenser filter element of this utility model, which is not prone to clogging, uses a positioning rod, groove, conical block, and sieve hole. The positioning rod and groove work together to provide positioning and guidance for the inner tank, ensuring sufficient stability on the inner wall of the outer shell. This also allows for easy alignment of the observation window with the through-hole on the outer shell surface, enabling users to observe the condition of the inner tank wall. The conical block and sieve hole work together to filter the water source, maintaining a high level of cleanliness, thus improving drinking water quality, reducing the risk of illness, and enhancing the safety of citizens' drinking water. Furthermore, the conical design of the conical block guides impurities to the surrounding area, ensuring unobstructed flow in the central area. Attached Figure Description

The positioning assembly 5 is fixedly installed on both sides of the surface of the inner liner 41. The positioning assembly 5 includes positioning rods 51 and grooves 52. There are four sets of positioning rods 51, which are fixedly installed in a ring on the inner wall of the outer shell 1. The grooves 52 are opened on the side of the inner liner 41 near the positioning rods 51. The inner liner 41 is slidably installed on the surface of the positioning rods 51 through the opening of the grooves 52. The filter assembly 6 includes conical blocks 61 and sieve holes 62. There are several sets of conical blocks 61, which are fixedly installed on the inner wall of the inner liner 41. The sieve holes 62 are opened on the surface of the conical blocks 61. The several sets of conical blocks 61 are installed longitudinally on the inner wall of the inner liner 41, and the diameter of the sieve holes 62 on the surface of each layer of conical blocks 61 gradually decreases from top to bottom. The inner liner 41 is made of PPR material.
[0020] like Figures 1 to 5As shown, the combined use of the threaded cylinder 31, sealing cap 32, and sealing ring 33 secures the inner liner 41, ensuring high stability during use and preventing leakage. It also facilitates filter replacement. The inner liner 41, in conjunction with the observation window 42, allows for easy disassembly and replacement of the filter assembly 6, and enables users to visually inspect the filter assembly 6 for blockages, facilitating timely replacement. The positioning rod 51 and groove 52 provide positioning and guidance for the inner liner 41, ensuring sufficient stability within the inner wall of the outer shell 1. They also allow for easy alignment of the observation window 42 with the through-hole on the surface of the outer shell 1, enabling users to properly observe the inner liner 41. The inner wall condition, the combined use of conical blocks 61 and sieve holes 62 can filter the water source, so that the water source can maintain a high degree of cleanliness, thereby improving drinking water quality, reducing the risk of illness, and improving the safety of citizens' drinking water. In addition, the conical design of the conical blocks 61 can guide impurities to the surrounding area, ensuring that the central area remains unobstructed. The longitudinal arrangement of multiple sets of conical blocks 61 can form a multi-stage filtration technology feature. At the same time, the diameter of each layer of sieve holes 62 is different, which can separate impurities in the water layer by layer, thereby ensuring that impurities do not accumulate in the same filter screen and cause blockage. The PPE material has high corrosion resistance and high temperature resistance, which can prevent the inner tank 41 from corroding due to the accumulation of impurities during use, and there is no risk of cracking when transporting hot water.
[0021] Working principle: During operation, first unscrew the sealing cap 32 and remove it from the inner wall of the threaded cylinder 31. Then, the user picks up the inner tank 41 and aligns the groove 52 with the positioning rod 51, sliding it from top to bottom into the inner wall of the outer shell 1. Next, reinstall the sealing cap 32 into the threaded cylinder 31. Then, connect the connecting end 2 and the sealing cap 32 to the water pipe in sequence for use. During use, when water flows into the inner tank 41, it is preferentially filtered by the conical block 61 and the sieve hole 62. Simultaneously, the multi-stage filtration by the conical block 61 and the sieve hole 62 separates impurities in the water according to their size. The layered isolation design prevents impurities from accumulating on the same filter screen and causing blockage. As the conical block 61 filters for a long time, its surface will accumulate more impurities. The unique conical design of the conical block 61 can guide the impurities to the surrounding area, thus keeping the raised part in the middle of the conical block 61 unobstructed. This allows water to flow normally without clogging, further reducing the risk of blockage and extending the lifespan of the filter cartridge. Users can also observe the amount of impurities filtered by the conical block 61 through the observation window 42, allowing for timely replacement before the conical block 61 becomes completely clogged.
