Abstract
The utility model discloses a filter element with a rapidly detaching bottle cover. The filter element comprises a filter bottle and an upper cover, wherein the upper end of the filter bottle is provided with a sleeved section; an outer edge of the sleeved section is provided with two embedded and clamped lugs opposite to each other; the two embedded and clamped lugs are respectively provided with at least one guide bevel edge and a positioning groove; an inner edge wall of the upper cover is provided with two supported and pressed lugs opposite to each other; the two supported and pressed lugs are respectively provided with a climbing slope and a positioning lug; and a fastening groove is respectively formed on the upper sides of the two supported and pressed lugs. Therefore, when the filter bottle and the upper cover are combined and fixedly embedded and clamped, positioning protrusions are clamped in the positioning grooves for auxiliary positioning, so the filter bottle and the upper cover are prevented from loosening so as not to cause water leakage and water flooding due to water hammer in filtering, and when the filter bottle and the upper cover are detached, the climbing slopes of the supported and pressed lugs of the upper cover are pressed against the guide bevel edges of the embedded and clamped lugs of the filter bottle in a sliding mode, so that the upper cover is automatically separated from the filter bottle.
Description
Technical field
The utility model relates to a kind of water purifier filter structure, relates in particular to a kind of filtering element (cartridge) that can quick and convenient dismounting bottle cap.
Background technology
Along with popularizing of health care's idea, the water quality of drinking water is also paid attention to by people gradually, so water purifier is just accepted by increasing family and used.And most water purifier is with the multiple tracks filtering element (cartridge) water quality to be filtered, and this filtering element (cartridge) includes a filter flask and a loam cake, and this filter flask inside is equiped with filter material.In early days, utilize internal and external screw thread to combine between this filter flask and loam cake with screw lock, though the still equal suitable complicacy and time-consuming of dismounting of this kind combination assembling, so practicality is not good.
Therefore; A kind of quick integrated structure of filtering element (cartridge) bottle cap is disclosed; It is provided with a shrinking section in the filter flask upper end; The outer rim of this shrinking section is provided with two inlay card projections respect to one another, and is provided with respect to one another two in the inner wall of loam cake and supports to arrive in projection or two buckle slots, utilizes turn mode inlay card to fix between this filter flask and loam cake thereby can make.This structural design is exposed in TaiWan, China and announces M360729 water purifier filtering element (cartridge) quick coupling structure, TaiWan, China and announce M337414 water purifier filtering element (cartridge) snap joint improved structure, TaiWan, China and announce the joint improvement and the TaiWan, China of M317286 filtering element (cartridge) and announce reverse osmosis filter structure improvement utility model patents such as (one) No. 560350.
Yet, combining and dismantle effort between the filter flask of the quick integrated structure of this known filtering element (cartridge) bottle cap and loam cake, and carry out disassembling section and after loam cake outwarded winding; Need again loam cake upwards to be mentioned or filter flask is fetched downwards; Just can make loam cake break away from filter flask, thereby disassembling section still fail to reach real quick and convenient, in addition when filter flask combines also inlay card fixedly with loam cake; The structural design that does not have assist location, so that situation loosening even that come off takes place easily.
