Description

Technical Field

[0001] This utility model relates to the field of filtration technology for bathroom fixtures and faucets, and in particular to a bathroom filter cartridge that can remove residual chlorine and hardness from water and has a long service life. Background Technology

[0002] Currently, most bathroom system filter cartridges are used to connect to hot water pipes. When replacing them, it is necessary to disassemble the threaded connectors on both sides of the filter bottle that connect to the pipes, which makes disassembly difficult. In addition, the filter media used in bathroom filter cartridges is composed of a mixture of various granular materials. When used for a long time, the filter media in the cartridge may become clogged due to water flow impact, resulting in a decrease in the filter cartridge flow rate.

[0003] In view of the above problem, a bathroom filter cartridge that can remove residual chlorine and hardness from water and has a long service life is designed. Utility Model Content

[0004] In view of the above-mentioned technical problems, this utility model provides a bathroom filter cartridge that can remove residual chlorine and hardness from water and has a long service life. It adopts a variety of connection methods to meet more usage needs, and the connection methods include threaded installation or hanging installation, which facilitates the installation and disassembly of the filter cartridge. Furthermore, by placing different filter media in the inner cavity of the multi-layered filter cartridge, the different filter media are placed in layers, thereby reducing the problem of filter cartridge clogging caused by filter media accumulation.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] This bathroom filter cartridge, capable of removing residual chlorine and hardness from water and boasting a long lifespan, is characterized by comprising a main body, an inner core body, end caps, and an inner core top cover. A main body filter screen is located at the water outlet at the bottom of the main body. An end cap is mounted on the top of the main body, and an end cap filter screen is located at the water inlet of the end cap. The inner core body is installed within the main body, and the inner core top cover is mounted on top of the inner core body. A connecting component is located at the water inlet of the end cap, allowing connection to a household water pipe. A first layer of filter media is mounted above the inner core top cover, a second layer of filter media is mounted above the inner core body, and a third layer of filter media is mounted above the main body filter screen.

[0007] The bottom of the inner core body and the top cover of the inner core are both provided with filter holes.

[0008] The connecting component is a connecting end cap, which is fixed to the water inlet end of the top of the end cap by bolts. The connecting end cap is provided with a connecting pipe, and the inner wall of the upper end of the connecting pipe is provided with an internal thread for connecting the pipe, so as to realize the threaded connection with the household pipe.

[0009] The connecting component is a hanging ring, with both ends of the hanging ring fixed to the water inlet end of the top of the end cap, and the hanging ring is installed on the faucet in a suspended manner.

[0010] The first, second, and third filter media are all different, and each of them is one of activated carbon, phosphate, and ion exchange resin.

[0011] The beneficial effects of this utility model are:

[0012] The bathroom filter element designed in this utility model has two types of connecting components on its end cap. When the connecting component is a connecting end cap, the connecting tube on the connecting end cap has an internal thread, which can be threaded to the pipeline to replace the shower faucet and realize a shower with a filtering function. When the connecting component is a hanging ring, it can be suspended and installed on the faucet to realize the effect of a faucet filter element. The installation method is diversified to meet more usage needs.

[0013] The filter cartridge designed in this utility model has its internal cavity divided into three layers by an inner core cover with filter holes and an inner core body. Each layer holds different filter media, thereby avoiding filter media accumulation caused by water flow impact, reducing the problem of filter cartridge blockage caused by filter media accumulation, and thus extending the service life of the filter cartridge. Moreover, these three different filter media are activated carbon, phosphate, and ion exchange resin. Activated carbon can effectively remove residual chlorine in water, while phosphate and ion exchange resin can effectively remove water hardness. Attached Figure Description

Filter holes are provided at the bottom of the inner core body 3 and on the inner core top cover 4. A connecting end cap 51 is installed at the water inlet end of the end cap 2. The connecting end cap 51 is fixed to the water inlet end of the top of the end cap 2 by bolts 53. A connecting pipe 52 is provided on the connecting end cap 51. The inner wall of the upper end of the connecting pipe 52 is provided with internal threads for connecting the pipeline, thereby realizing the threaded installation of the filter element with the household pipeline.

[0027] Furthermore, a first layer of filter material is installed in the cavity above the inner core cover 4 in the filter element; a second layer of filter material is installed in the cavity formed by the upper part of the inner core body 2 and the inner core cover 4; and a third layer of filter material is installed in the cavity formed between the upper part of the body filter screen 11 and the bottom of the inner core body 2. These three layers of filter material are different filter materials. The three filter materials can be activated carbon, phosphate, and ion exchange resin, and can be placed in the filter element in any arrangement. For example, the first layer of filter material is activated carbon, the second layer of filter material is phosphate, and the third layer of filter material is ion exchange resin, or the first layer of filter material is phosphate, the second layer of filter material is activated carbon, and the third layer of filter material is ion exchange resin, and so on, in multiple arrangements.

A body filter screen 11 is provided at the water outlet end of the bottom of the body 1. An end cap 2 is installed on the top of the body 1. An end cap filter screen 21 is provided at the water inlet end of the end cap 2. The inner core body 3 is installed inside the body 1. An inner core top cover 4 is installed on the top of the inner core body 3. Filter holes are provided at the bottom of the inner core body 3 and on the inner core top cover 4. A hanging ring 61 is installed at the water inlet end of the end cap 2. The two ends of the hanging ring 61 are fixed to the water inlet end of the top of the end cap 2. The hanging ring 61 is suspended and installed on the faucet.

[0032] Furthermore, a first layer of filter material is installed in the cavity above the inner core cover 4 in the filter element; a second layer of filter material is installed in the cavity formed by the upper part of the inner core body 2 and the inner core cover 4; and a third layer of filter material is installed in the cavity formed between the upper part of the body filter screen 11 and the bottom of the inner core body 2. The three layers of filter material are different filter materials. The three filter materials can be activated carbon, phosphate, and ion exchange resin, and can be placed in the filter element in any arrangement. For example, the first layer of filter material is activated carbon, the second layer of filter material is phosphate, and the third layer of filter material is ion exchange resin, or the first layer of filter material is phosphate, the second layer of filter material is activated carbon, and the third layer of filter material is ion exchange resin, and so on, in multiple arrangements.

[0033] By layering three different filter media, the accumulation of filter media caused by water flow impact is avoided, reducing the problem of filter cartridge clogging caused by filter media accumulation, thereby extending the service life of the filter cartridge. Moreover, these three different filter media are activated carbon, phosphate, and ion exchange resin. Activated carbon can effectively remove residual chlorine in water, while phosphate and ion exchange resin can effectively remove water hardness.
