Technical Field

The utility model belongs to the technical field of purifier, especially, relate to kinds of cut straightly filter core that does not have upper and lower cover.

Background

The inner structure of a clamped filter element or a direct-insert filter element and a front filter element PP cotton filter element in the market is that end covers are respectively arranged on the upper part and the lower part of PP cotton, the filter element is packaged into the filter element after being assembled in a hot melt adhesive sticking mode, or the upper end cover and the lower end cover press the PP cotton through a circular pointed rib on the end covers.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide kinds of cut straightly filter cores that do not have upper and lower lid, it has solved the current formula filter core that cut straightly technical problem that the cost is higher, production efficiency is lower.

In order to achieve the above purpose, the utility model provides a technical scheme does:

the utility model discloses a kind of cut straightly filter core that does not have upper and lower cover, it includes the filter core barrel, be equipped with the filter core in the filter core barrel, the upper end of filter core barrel is connected with barrel upper cover, wherein, cover on the barrel and be equipped with inhalant canal and exhalant canal, inhalant canal and exhalant canal communicate respectively in the inside and the intermediate layer chamber between filter core and the filter core barrel of filter core, and the medial surface of barrel upper cover is equipped with bellied annular wall, and when the barrel upper cover was connected to the filter core barrel, annular wall extruded in the tip of filter core.

Wherein, the top of the annular wall is also provided with a sharp-angled rib.

Wherein, the terminal surface of the inboard side of barrel upper cover still is equipped with bellied second annular wall.

And the top of the second annular wall is also provided with a sharp-angled rib.

Wherein, the th annular wall and the second annular wall are arranged in parallel.

Wherein, the filter element cylinder is cylinder with an opening end and a closed end.

Wherein, the filter core is PP cotton.

Compared with the prior art, the utility model discloses a cut straightly filter core of no upper and lower cover, its tip angle muscle structure that designs into the terminal surface of the barrel upper cover that will have now and has protruding annular wall compresses tightly with the terminal surface of filter core after the equipment to save the trouble of installing the end cover alone, cost reduction has improved production efficiency simultaneously.
