Description

Technical Field

[0001] This utility model relates to the field of water purifiers, and in particular to a filter element structure. Background Technology

[0002] A water purifier is a device used for deep filtration and purification of water. It can remove impurities, odors, heavy metals, bacteria, viruses and other harmful substances from water, thereby improving water quality and making it more suitable for drinking, cooking or other household uses.

[0003] The filter cartridge is the core component of a water purifier; it is an element with filtration function. It is made of specific filter materials and purifies water through physical or chemical methods, removing various impurities and pollutants to improve water quality.

[0004] Most existing filter cartridges are detachably installed in water purifiers. After a period of use, the entire filter cartridge is replaced. Filter cartridges usually use a single filtration material. If all high-capacity materials are chosen, the cost is too high. If all low-capacity materials are chosen, the filtration level is too poor. Moreover, because the filter cartridge has a certain length, the water flows from the front end to the back end, and the impurities decrease as it flows. The front end is often the first to lose its filtration capacity, while the back end still maintains good filtration capacity. In order to ensure the water purification effect, the entire filter cartridge is usually replaced when the front end has lost its water purification capacity. This is very costly and wasteful. Utility Model Content

[0005] To overcome the above problems, this utility model provides a filter element structure. The technical solution adopted by this utility model to solve its technical problems is as follows:

[0006] A filter element structure includes a detachably fixedly connected primary filter head and a secondary filter head.

[0031] To better understand the purpose, structure, and function of this utility model, the following detailed description, in conjunction with the accompanying drawings, provides a further detailed description of specific embodiments of the utility model, namely, "a filter element structure, a water purification head, and a viewing window horizontal faucet water purification structure".

[0032] See Figures 1-3 In this embodiment, the filter element structure includes a detachably fixedly connected primary filter head 100 and a secondary filter head 101. The primary filter head 100 is filled with a coarse filter material 102. Preferably, the coarse filter material 102 is a filter material composed of silk cotton and carbon fiber. The secondary filter head 101 is filled with a fine filter material 103. Preferably, the fine filter material 103 is an ultrafiltration material with a pore size of 0.1-0.01 micrometers. The liquid flows in from the inlet end 104 of the primary filter head 100, passes through the coarse filter material 102 and the fine filter material 103 in sequence, and then flows out from the outlet end 105 of the secondary filter head 101. This filter cartridge uses a detachable two-stage filter head structure. The first-stage filter head 100 at the front end is filled with a lower-cost, lower-level coarse filter material 102, while the second-stage filter head 101 at the rear end is filled with a higher-cost, higher-level fine filter material. This not only ensures filtration capacity but also saves costs. Furthermore, the coarse filter material 102 at the front filters out large impurities that are prone to clogging and loss of filtration capacity. When the first-stage filter head 100 loses its filtration capacity, it can be removed and replaced with a new one, while the usable and more expensive second-stage filter head 101 is retained. This eliminates the need to replace the entire filter cartridge, ensuring filtration capacity while optimizing costs.

[0033] See further Figure 1 and Figure 2 In this embodiment, the water inlet 104 is designed as a vortex structure. When liquid flows in from here, the vortex structure can agitate the liquid, so that impurities in the liquid can enter the primary filter head 100 evenly, which can improve the service life of the primary filter head. In addition, the vortex structure can increase the water flow rate and improve the water purification efficiency.

[0034] See further Figure 2 and Figure 3 In this embodiment, in order to ensure the sealing of the connection between the primary filter head 100 and the secondary filter head 101, a first rubber ring 106 is provided at the connection position of the primary filter head 100 and the secondary filter head 101 to ensure the sealing of the connection.

[0035] This utility model also includes a water purifier head, see [link to relevant documentation] Figures 4-7In this embodiment, the water purifier head includes a cylindrical body 200, a first end cap 201, and a second end cap 202. The first end cap 201 and the second end cap 202 are detachably and fixedly connected to both ends of the cylindrical body 200 to form a sealed chamber. Rubber rings are provided at the connection positions of the first end cap 201 and the second end cap 202 with the cylindrical body 200 to ensure airtightness. The above-mentioned filter element structure is detachably and fixedly installed inside the cylindrical body 200. The filter element structure divides the sealed chamber into a primary chamber 203 and a secondary chamber 204. The primary filter head 100 is located in the primary chamber 203, and the secondary filter head 101 is located in the secondary chamber 204. The cylindrical body 200 is also provided with a water inlet 205 and a purified water outlet 206. The water inlet 205 is connected to the primary chamber 203, and the secondary chamber 204 is connected to the purified water outlet 206. Water flows in through inlet 205, enters the filter element structure via inlet 104, and after being filtered by primary filter head 100 and secondary filter head 101, flows into secondary chamber 204 through outlet 105, and then flows out through purified water outlet 206. Inlet 205 is detachably connected to various water outlets, making it widely applicable; the filter element and cylinder 200 are detachably fixed, facilitating disassembly and replacement, and combined with the aforementioned filter element structure, it saves costs.

[0036] See further Figure 1 , Figure 2 and Figure 6 , Figure 7 In this embodiment, a positioning groove 107 is provided circumferentially on the outer wall of the filter element structure, and a second rubber ring 108 is provided in the positioning groove 107. An isolation clamp 207 is provided circumferentially on the inner wall of the cylinder 200. The second rubber ring 108 abuts tightly against the inner wall of the isolation clamp 207 to divide the sealed chamber into an independent primary chamber 203 and a secondary chamber 204.

[0037] See further Figure 4 and Figure 5 In this embodiment, the first end cap 201 is located at the top of the primary chamber 203. The top surface of the first end cap 201 is transparent to allow observation of the primary filter head 100 and water flow. If blockage or poor water flow is observed through the transparent top of the first end cap 201, the primary filter head 100 needs to be replaced as soon as possible to prevent a decrease in the water purification capacity. The second end cap 202 is located at the top of the secondary chamber 204. An indicator knob 208 is provided on the top of the second end cap 202, and a month mark is provided around the indicator knob 208. Rotating the indicator knob 208 to the corresponding month mark allows recording the month in which the filter element needs to be replaced, ensuring that the filter element is replaced regularly to avoid forgetting and affecting the health of the water used.

[0038] This embodiment also includes a window-type horizontal faucet water purification structure, see [link / reference] Figure 8 and Figure 9In this embodiment, the faucet water purifier includes a core valve assembly 300 and the aforementioned water purifier head.
