Second type filter core is the filter core that comprises a kind of adjustable in length, and the filter core of this filter core can be regulated length, can with the use that is complementary of multiple urceolus.This type filter core has solved some difficult problems that run in the filter core of traditional handicraft manufacturing production largely, and satisfies the market demand of nonstandardized technique filter core.
People such as Hoffman are at United States Patent (USP) 7; 473; Described a kind of filter core about adjustable length among the 360B2, it has disclosed the instance that the end cap that utilizes adjustable length and multiple filter core urceolus are complementary and use, and said end cap has an annular element; Lean on tightly mutually with round neck on the said end cap through sealing ring, form the cooperation of a sealing.More convenient when although the filter core of this adjustable in length uses through the filter core of traditional handicraft making the first kind, also there are some defectives.At first, more renew cartridge is very time-consuming, needs to take out through the handle on the end cap earlier the top cover of end cap, and then takes out whole filter core.In addition, the sealing of length adjustment parts and annular element is not very desirable, and particularly circular neck portion divides to skid off easily and leaves sealing ring, occurs that sealing effectiveness lost efficacy or top cover skids off annular element and the phenomenon that drops.
Summary of the invention
The utility model has overcome the defective and the restriction of prior art, and a kind of cylinder filter core of improved adjustable in length is provided.This filter core has a flange protection structure; So-called flange protection structure is meant a circle flange of round neck lower end; The internal diameter that its external diameter encircles down greater than annular element; Be used to prevent that top cover from skidding off annular element, and realize that more renew cartridge is time saving and energy saving that the handle that only needs lift end to cover can take out whole filter core.Specifically, the filter core of this adjustable in length comprises the end cap of a circular filter element, a bottom and at least one adjustable in length.This filter element one end and the sweat soldering mutually of this bottom.The end cap of adjustable in length has an annular element, a round neck and a top cover.Annular element has the ring of going up and encircles two parts down, and following ring and the sweat soldering mutually of the filter element other end, last ring snap in down ring, form an interlayer groove.Sealing ring is installed in the interlayer groove, and leans on tightly mutually with a round neck.The circle neck can vertically move, and there is a circle flange round neck lower end, and this circle lip diameter makes round neck can not skid off annular element greater than the internal diameter that fixing endless member encircles down.Top cover of circle neck upper end adhesion has a grip and a circle outer rim in the middle of the top cover, a circle sealing ring is being overlapped in the outer rim outside.Endless member down ring hot melt makes the circle filter element internal passage that coordinates on an end of cylinder filter element, this passage seals basically.
