    Abstract: A filter element includes a ring of filtration media circumscribing a central axis and defining a central cavity. An annular end cap of the filter element is sealingly bonded at an end of the media. The end cap includes a central opening into the central cavity, and a lateral opening spaced laterally outward from the central opening. The central opening includes a threaded connection portion to enable the element to be spun-on to a complimentarily-threaded connection portion of a filter head. The connection portion of the central opening includes at least one axially-extending slot opening radially away from the connection portion.

    Abstract: A filter and its holder each have a keyed surface, one being a protruding “key” and one being a recessed “lock,” wherein cooperation of these keyed surfaces is required in order for the filter to be installed in the holder. Modification/adaptation of the keyed surfaces, by changing the location, number and length of the key protrusions and cooperating recesses during manufacture, allows various sets of mating filters and holders to be produced so that only mating/matching filters and holders may be connected together. The keyed protrusions are preferably located on an upper shoulder or on protruding flange(s) of the upper end of the filter. The cooperating recess structure inside the filter holder comprises axial recesses that allow axial insertion of the key protrusions, and hence the filter, into the holder and also a circumferential recesses portion that receives multiple key protrusions to retain the filter in the holder. This way, multiple key protrusions slide into and are retained in a single circumferential recess/slot, rather than each key protrusion being received in its own separate circumferential recess/slot.

    Abstract translation: 过滤器及其保持器各自具有带键表面，一个是突出的“键”，一个是凹入的“锁定”，其中需要这些键合表面的协作以使过滤器安装在保持器中。 通过在制造过程中改变键突起和配合凹槽的位置，数量和长度来改变键盘表面的修改/改编，允许制造各种配套的过滤器和保持器，使得只有匹配/匹配的过滤器和保持器可以连接在一起 。 键合的突起优选地位于过滤器的上端的上肩部或突出的凸缘上。 过滤器保持器内部的配合凹槽结构包括轴向凹槽，其允许将键突起部以及因此的过滤器轴向插入到保持器中，并且还包括容纳多个键突起以将过滤器保持在保持器中的周向凹部。 这样，多个键突起滑入并保持在单个周向凹槽/槽中，而不是每个键突起被容纳在其自己的独立的周向凹槽/槽中。

    Abstract: A filter assembly for fluid filtration having a push-activated lock and release mechanism. A push filter design activates a floating key lock upon insertion and extraction, where the filter key may be used simultaneously as a lock and as an identifier for particular filter attributes. The filter base may be situated inline, and in fluid communication, with influent and effluent piping, such as within a refrigerator. The filter housing assembly may be attached to, and removed from, the filter base by a push-actuated release. Upon insertion, the filter key shifts the filter lock longitudinally to receive interlocking segments. Upon extraction, the same axial push shifts the filter lock further to align the interlocking fingers within gaps that allow for easy extraction. The specific key lock design allows a user to identify and match certain filter configurations received by the mechanical support, and reject other filter configurations.

    Abstract: A water filter has a filter body, a filtering tube and an assembling cover. The engaging portion of the filtering tube securely engages with the water channel of the assembling cover, and the engaging disk of the filtering tube securely engages with the engaging circular rib of the filtering space, such that the filtering tube is securely limited and positioned between the filter body and the assembling cover; furthermore, the filtering tube, the filter body and the assembling cover respectively engage with each other and are combined together by the welding process, to completely prevent the filtering tube from deforming and misplacing.
