Description

Filter element mounting structure for water purifier

Technical Field

The utility model relates to the field of filter elements of water purifiers, in particular to a filter element mounting structure for a water purifier.

Background

The water purifier is also called as water purifier and water filter, and is water treatment equipment for deeply filtering and purifying water. The filter core that adopts in the common water purifier has three kinds of cotton filter core of PP, active carbon filter core and RO reverse osmosis membrane filter core, purifies water through the filter core, but along with live time's extension, the filter core can be blockked up to the impurity of aquatic, and the active carbon filter core can adsorb the saturation, and PP filter core just need be changed in 3 months generally speaking, and the active carbon filter core then needs 6 months to change. Because often include the different filter cores of a plurality of life-spans in the water purifier of a multistage filter core, need operate the filter core that needs to be changed alone when changing, and the space between the inner wall of straining a section of thick bamboo and the outer wall of filter core is less, causes the user to visit very inconveniently when taking out the filter core finger.

Therefore, the existing water purifier is improved in the structure of replacing the filter element so as to realize the purpose of conveniently taking and placing. For example, chinese patent application No. CN202010782112.2 discloses a filter element structure for quick installation, in which a filter element cavity is provided on a filter element body, a handle is hinged to a connecting portion, a clamping limiting portion is provided at the hinged end of the handle protruding outwards, and the clamping limiting portion is rotated and pressed in a limiting groove provided on a filter element seat for limiting. Although this structure is through increasing limit structure on the handle of filter core to can utilize lever principle to impress the filter core cavity of water purifier with the filter core, and realize the auto-lock, in this patent, the position of connecting portion two sides can not only play water connection's effect, can also provide stable support to the filter core when leading to water, avoids it to rock. But to different filter core structures, the water route connection form is different, and in case the position design of logical water is in other regions, only has the handle of top spacing, and the filter core produces the swing under hydraulic effect very easily, and then leads to the water route connection insecure.
