Description

Technical Field

[0001] This utility model relates to the field of water purifier filter technology, specifically, it is a replacement filter element and water purification equipment for a four-inlet / outlet composite filter element. Background Technology

[0002] As water purifiers continue to improve, the demand for filter replacement is also increasing. Existing water purifier filters include: filter cover, filter cartridge, and filter media encapsulated inside the filter cartridge.

[0003] The following problems exist with water purification equipment on the market: Firstly, the products are often bulky, taking up a significant portion of kitchen cabinet space and leaving less room for other appliances, hindering efficient cabinet layout and resulting in wasted space. Secondly, while composite filter cartridges reduce space requirements, their structure necessitates dedicated water channels to support them, increasing the versatility of the equipment and its integration with other functions. This structure wastes resources and increases manufacturing costs. Furthermore, while some four-head dual-channel filter cartridges employ multi-stage purification, their complex structure within a single cartridge results in limited filter material, poor purification performance, and high manufacturing costs. Utility Model Content

[0004] In order to solve the above-mentioned technical problems and provide consumers with a filter element that can reduce space occupation, has a reasonable layout, and is simple to use, this utility model discloses a replacement filter element and water purification equipment with a four-inlet and four-outlet composite filter element.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] A composite filter cartridge with four inlets and outlets is provided, consisting of three parts: a filter cover, a filter cartridge, and a filter base. The filter cover is manufactured using an integral injection molding process and is attached to the water purifier. The filter cartridge is cylindrical, with the filter cover fixed to one end and the filter base fixed to the other end. Filter media is placed inside the enclosed space of the filter cartridge. Two inlets and two outlets are provided at the connection point between the filter cover and the water purifier, designated as the first inlet, second inlet, first outlet, and second outlet, respectively. Two sealing rings are provided on the upper end of the filter media cover, sealing the lower parts of the second inlet and second outlet, allowing water to flow in through the second inlet and out through the second outlet.

[0007] In the above technical solution, the filter element shell consists of three parts: filter element cover, filter element cylinder and filter element bottom, forming a three-section structure. All three parts are made of PP material.

[0008] In a further improvement of this utility model, the first inlet, second inlet, first outlet, and second outlet of the single filter element are not connected. The first inlet is connected to the filter material. The pipe between the filter material and the filter material inside the filter element forms a water channel, which is designated as the first water channel. A sealing ring is provided at the lower part of the second inlet and the second outlet to form a water channel, which is designated as the second water channel. The water of the water purifier enters the filter material through the first inlet, is filtered, and then flows out of the first outlet through the first water channel into the water purifier. Similarly, the water of the water purifier enters the second water channel through the second inlet and flows out of the second outlet into the water purifier.

[0009] The filter cartridge cover, filter cartridge bottom, and filter cartridge can be connected in various ways. For ease of maintenance and filter media replacement, the connection can be detachable, such as by threaded connections. However, since the filter cartridge housing is used to hold the filter media connected to the water purifier, to prevent leakage, the filter cartridge cover and filter cartridge bottom in this invention are welded to both ends of the filter cartridge, forming a well-sealed space that has passed pressure testing and achieves a leak-proof effect. Furthermore, the filter cartridge contains a single independent filter media. Compared to the common practice of using two concentric filter media in the market, this single media eliminates one filtration step, saving filter media. To increase filtration efficiency, another filter media can be connected in series outside the filter cartridge, simplifying production and reducing costs, thus lowering the product price.

[0010] A further improvement to this invention is that the bottom of the filter element contracts inward to form a groove. During filter element replacement, the thumb of the user can press against the groove, giving the filter element housing an upward lifting force, making it easier to install and disassemble.

[0011] A further improvement to this invention is that the filter material is activated carbon.

[0012] This utility model also discloses a water purification device that uses the above-mentioned four-inlet / outlet composite filter element as a substitute filter element.

[0013] The beneficial effects of this utility model are as follows: Compared with the commonly used double concentric circle filter media on the market, this utility model only uses one filter media, which simplifies the production process, reduces the number of filter media used, thereby reducing production costs and product prices. In addition, the filter element is smaller in size and occupies less space, which is conducive to space arrangement. Attached Figure Description

[0018] To enhance understanding of this utility model, it will be described in further detail below with reference to the accompanying drawings and embodiments. These embodiments are only used to explain this utility model and do not limit the scope of protection of this utility model.

[0019] Example: Figure 1 and Figure 2 As shown, a composite filter cartridge with four inlets and outlets consists of three parts: a filter cartridge cover, a filter cartridge 5, and a filter cartridge bottom 8, all made of PP material. The filter cartridge cover is manufactured using an integral injection molding process and is attached to the water purifier. The filter cartridge 5 is cylindrical, with the filter cartridge cover fixed to one end and the filter cartridge bottom 8 fixed to the other end. Filter media 6 is placed inside the enclosed space of the filter cartridge 5. The position where the filter cartridge cover connects to the water purifier is provided with two inlets and two outlets, designated as the first inlet 1, the second inlet 2, the first outlet 4, and the second outlet 3, respectively. Two sealing rings 7 are provided on the upper end of the filter media 6, sealing the lower part of the second inlet 2 and the second outlet 3. The first inlet 1, second inlet 2, first outlet 4, and second outlet 3 of the four-inlet / outlet composite filter cartridge are not connected. The first inlet 1 is connected to the filter material 6. The pipe 9 in the middle of the filter material 6 inside the filter cartridge 5 forms a water channel, which is designated as the first water channel. The lower part of the second inlet 2 and the second outlet 3 is provided with a sealing ring 7 to form a water channel, which is designated as the second water channel. The water of the water purifier enters the filter material 6 through the first inlet 1, is filtered, and then flows out of the water purifier through the first water channel and the first outlet 4. Similarly, the water of the water purifier enters the second water channel through the second inlet 2 and flows out of the water purifier through the second outlet 3.

[0020] like Figure 3 As shown, the bottom of the filter element 8 tapers inward to form a groove 10. During filter element replacement, the thumb of the user can press against the groove 10, giving the filter element housing an upward lifting force, making it easier to install and remove.
