[0002] As living standards continue to improve, people pay more and more attention to drinking water safety. As tap water in cities is easily contaminated due to aging of water pipelines during transportation, in order to ensure drinking water safety, more and more users are beginning to choose water purifiers to purify tap water. The water filter in the water purifier can remove impurities and odors in tap water and is an important component for purifying water quality.

[0003] During the assembly process of the water filter element, it is necessary to first fill the filter element housing with carbon materials, such as fine carbon powder and coarse carbon particles, and then assemble the filter element top cover to the top of the filter element housing. After welding with an ultrasonic welding machine, the sealing ring is set on the filter element housing from the bottom, and then the sealing ring is pressed into the groove of the filter element housing with a tool to ensure that the connection between the water filter element and the water purifier is sealed, and to prevent the raw water from directly entering the clean water tank from the connection between the water filter element and the water purifier, causing the clean water to be contaminated; finally, the valve plate is installed on the water outlet at the bottom of the filter element housing to adjust the flow rate of the clean water. There is a protrusion on the outer edge of the valve plate to facilitate the valve plate. When installing the valve plate, it is also necessary to ensure that the protrusion on the valve plate is at the starting end. Finally, after the assembly is completed, quality inspection is required to select products with unqualified weight.
