A water purifier filter element with protective structure

Abstract

The invention provides a water purifier filter element with a protective structure, including a filter cartridge assembly, a filter element assembly, a filter element press assembly, and a water inlet and outlet assembly; The pipeline is connected, the water inlet pipe and the water outlet pipe are inserted into the water inlet port and the water outlet port of the filter cartridge assembly, and then pressed by the pressure rod under the action of the torsion spring, and will not fall off due to external force; the filter cartridge and the cartridge in the filter cartridge assembly After the cover is clamped by the bayonet pin in the filter element clamping assembly, a safety cover is covered outside the bayonet pin to ensure that the filter cartridge and the cylinder cover are installed securely; the filter element body in the filter element assembly inside the filter cartridge assembly is provided with a filter element The sheath ensures that the main body of the filter element will not be deformed under the action of water pressure, which will affect the filtration and purification effect.

Description

technical field [0001] The invention relates to the field of water purifiers, in particular to a water purifier filter element with a protective structure. Background technique [0002] As the water environment is increasingly polluted, in order to ensure the health of drinking water, more and more water purifiers have entered the family. Traditional water purifiers use one-stage or multi-stage filter elements in series for filtration and purification. The filter elements of each stage need to be connected by pipelines. Generally, quick-plug methods are used. The filter material is either placed in the In the filter cartridge, or adopt the integral disposable type. [0003] However, no matter which method is used, there are certain shortcomings. The method of threaded connection to replace the filter material independently requires a high degree of specialization of the operator. After the replacement, leaks are prone to occur due to poor sealing, and the insertion of each ...

[0003] However, no matter which way, there are certain shortcomings. The method of self-replacing the filter material with threaded connection requires a high degree of specialization of the operator. After the replacement, it is prone to leakage due to poor sealing, and the insertion of each pipe fitting is not in place. , the joints will also leak water, which will affect the use; and when the life of the fully disposable filter element expires, it will be discarded as a whole, and the waste rate is high
