Abstract

The utility model belongs to the technical field of filters, and particularly relates to a filter device. The filter device comprises a barrel, an upper cover and a lower cover, wherein the upper cover is connected to the upper end part of the barrel in a clamping manner, and the lower cover is connected to the lower end part of the barrel in a clamping manner; the upper end surface of the upper cover and the lower end surface of the lower cover have a through hole respectively, and a filter core is arranged inside the barrel; and both the lower side inner wall of the upper cover and the upper side inner wall of the lower cover are respectively provided with a snap ring, and the outer edge of the upper end part and the outer edge of the lower end part of the barrel are respectively provided with a groove which is matched with the snap ring. The filter device is simple in structure and easy to assemble and maintain because of the clamping structure of the upper cover, the lower cover and the barrel.

Description

A kind of filter

Technical field

The utility model belongs to filtration art, is specifically related to a kind of filter.

Background technology

At present, the structure of the tubular filter on market is mostly comparatively coarse, and its upper and lower covers and cylindrical shell directly adopt the glue adhesion, not only waste material, and can not safeguard.

Summary of the invention

In order to overcome above shortcomings part in prior art, it is a kind of simple in structure, safe and reliable that the purpose of this utility model is to provide, and cost is lower, and practicality is good, the filter of easily accepting for market.

In order to reach above-mentioned purpose, the utility model adopts following concrete technical scheme:

A kind of filter comprises cylindrical shell, is connected to the upper cover of cylindrical shell upper end and is connected to the lower cover of cylindrical shell bottom; The upper surface of upper cover, the lower surface of lower cover all offer through hole, are contained with filter core in cylindrical shell; The inwall of the inwall of upper cover downside, lower cover upside is provided with snap ring, and the outer of cylindrical shell upper and lower end parts forms the groove that coordinates with described snap ring.

Described filter core is granular activated carbon, is provided with non-woven fabric plate in upper cover and lower cover; Evenly be provided with the catch that several increase lid intensity on the inwall of described upper cover, have at least two upper edges that are positioned at collinear catch to extend to form in opposite directions parting bead.

All sides of described cylindrical shell are evenly equipped with some anti-skidding raised lines.

Be evenly equipped with several notches on the corner disc of the side of described lower cover and bottom surface.

Compared with prior art, the utlity model has following outstanding advantages and effect:

Of the present utility model simple in structure, upper and lower covers and cylindrical shell are interface arrangment, are easy to assembling and safeguard.

The specific embodiment

As shown in Fig. 1-8, a kind of filter comprises cylindrical shell 2, is connected to the upper cover 1 of cylindrical shell 2 upper ends and is connected to the lower cover 3 of cylindrical shell 2 bottoms; The lower surface of the upper surface of upper cover 1, lower cover 3 all offers through hole, is contained with filter core in cylindrical shell 2; The inwall of the inwall of upper cover 1 downside, lower cover 3 upsides is provided with snap ring 12, and the outer of cylindrical shell 2 upper and lower end parts forms the groove 21 that coordinates with described snap ring 12.

Described filter core is granular activated carbon, is provided with non-woven fabric plate in upper cover 1 and lower cover 3; Evenly be provided with the catch that several increase lid intensity on the inwall of described upper cover 1, have at least two upper edges that are positioned at collinear catch to extend to form in opposite directions parting bead 11, the design of parting bead is for non-woven fabric plate is pressed on the granular activated carbon filter core.

All sides of described cylindrical shell 2 are evenly equipped with some anti-skidding raised lines.

Be evenly equipped with several notches 31 on the corner disc of the side of described lower cover 3 and bottom surface, this is established and is convenient to extraneous water and enters by lower cover and enter in cylindrical shell.

It should be noted that at last: above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
