A FILTER CORE ASSEMBLY FOR FILTERING LIQUID AND A WATER PURIFIER COMPRISING SUCH FILTER CORE ASSEMBLY FOR
FILTERING LIQUID Field of the Invention
The present invention relates to a filter core assembly for filtering liquid and a water purifier comprising such filter core assembly for filtering liquid.
Background of the Invention
The filter core assembly for filtering liquid is usually installed in a fluid filtration device, in particular a water purifier. This type of filter can filter some of the contaminants in the fluid or water, such as some particles, bacteria, macromolecules, heavy metal ions, toxic chemical constituents, and the like. For example, water purifiers typically include a filter core assembly that filters impurities, and the filtered raw water removes the heavy metals, bacteria, viruses, and other contaminants from the filter to achieve the purpose of purification to reduce the risk of drinking into unhealthy water. The existing filter for filtering liquid is usually made as a whole, can be directly installed in the fluid filter device, when the need to replace, the direct replacement of the entire filter. However, the different filter materials in the filter life of different, direct replacement of the entire filter will lead to the entire filter life is limited by the shortest life of the filter material constraints, which led to unnecessary waste and increase the cost of use.
Taking into account the health of drinking water safety, more and more people are concerned about the safety of drinking water. Therefore, the filter for the purification of water is applied to household containers or can be carried to the outdoor container to protect people's drinking water safety. For example, in the paper CN201454183, there is described a filter cartridge which is easy to carry when people are going out and can filter impurities effectively and purify water quality and a container provided with the filter core assembly. The filter sleeve is placed directly on the water container, and the drinker needs to suck the suction nozzle of the container cover to filter the filtered water through the filter and reach the mouth of the drinker. However, the filtration process is long and inefficient, and users often have to wait for a long time to drink very little filtered water. It is also inconvenient for the drinker to draw water from the container, And the filter components are set in the filter, cannot be based on the use of different and different needs of users to make adjustments, so the user experience is not ideal.
An improved method is to improve the efficiency of the filtered water by pressurization, and CN202069123 proposes a portable water cup comprising a combination filter comprising a ceramic filter core assembly and a fine particle bulk activated carbon filter core assembly, the portable water cup comprising the pressurizing device presses the water into the combined filter core assembly for filtration. Although this combination filter is assembled in a hierarchical manner, the ceramic filter cartridge can be removed and cleaned repeatedly, but the interface between the ceramic filter and the fine particle bulk activated carbon filter
In addition, the use of a pressurizing device to improve the efficiency of the filtration water and the use of a graded combination filter to improve the filtration performance is as described, for example, in WO2008053395, which is a general purpose water filtration unit assembly device having a pressurizing device and a multistage , the filter efficiency is increased by the pressurizing means, but it additionally requires a plurality of sealing rings to seal the plurality of connecting portions of the multi-stage combination filter core assembly and the need to install the check valve to prevent the return of the filtered water. Therefore, its structure is more complex to improve the production costs. And the filter rods proposed in the prior art are directly connected to the water container, and when the fresh water is to be filtered, the filter core assembly is removed from the water container and the water to be filtered is poured into the container, of the filter to filter. This frequent installation and removal operation can easily lead to the connection between the filter and the container damage, so that the filter may be due to local damage and cannot continue to use.
In addition, the usual filter core assembly, after its use of the cycle of arrival, almost needs to be replaced the whole, which greatly increases the cost of the use of the filter, but also caused more waste caused by environmental pollution.
