Abstract

A novel filter element comprises a filter cylinder, a net cylinder, an upper end cover and a lower end cover, wherein the upper end face and the lower end face of the filter cylinder are respectively sealed and wrapped by flexible glue layers; the net cylinder is fixedly connected with the lower end cover; the filter cylinder and the net cylinder are detachably connected with the upper end cover and the lower end cover at two ends. The novel filter element has the following benefits: the upper end face and the lower end face of the filter cylinder are respectively sealed and wrapped by the flexible glue layers, and the flexible glue layers can seal the upper end face and the lower end face of the filter cylinder to prevent the upper end face and the lower end face of the filter cylinder from air or oil leakage; in addition, after solidification of the flexible glue, the surface of the flexible glue is smooth and does not bond, so that the upper end cover and the lower end cover sealed and wrapped by the flexible glue layers do not bond with the flexible glue layers and are detachably connected; moreover, after solidification of the flexible glue, the flexible glue layers have certain elasticity, so that the upper end cover and the lower end cover sealed and wrapped by the flexible glue layers are excellently sealed. Therefore, when the filter element is replaced, only the filter cylinder instead of the entire filter is replaced, the using cost is reduced, waste is greatly avoided, and pollution is controlled.

Description

Novel filter filter core

Technical field:

The utility model relates to filter cleaner, relates generally to Vehicular cleaner, particularly the filter core of Vehicular cleaner.

Background technique:

Vehicular cleaner comprises air-strainer and oil rectifier, the two includes shell and filter core two parts, shell refers to the housing that is wrapped in filter core outside, filter core is the assembly parts for filtering, that the parts such as the upper and lower end cap by filter cylinder, its Intranet cylinder and filter cylinder and net cylinder form, filter cylinder generally becomes cylinder to form by filter paper paper folding, also can adopt felt, nonwoven cloth material to make.

Air-strainer is positioned at engine aspirating system, air is introduced between filter housing and filter core, then after filtering, filter cylinder enters cylinder through suction tude, its effect is the airborne objectionable impurities that filtering enters cylinder, for motor provides clean air, to reduce the wearing and tearing of impurity to cylinder, piston, piston ring, valve and valve seat etc. in air.Its defect of the filter core of existing air-strainer is: filter cylinder, its upper and lower two ends of net cylinder of forming filter core are adhered to one by adhesive and upper and lower end cap, can not be split, and when replacing, can only change integral filter core.More than 10,000 kilometer of automobile running, the some months time of travelling need to change filter element, the amount of the old filter core changing is very large, and the upper and lower end cap of filter core and net cylinder wait parts no matter be metal or all nonmetallic or can continue use, that can not continue use only has paper filter cylinder or felt filter cylinder.Together with the filter cylinder that can continue upper and lower end cap and the net cylinder using and can not continue to use, throwing away is a waste greatly, moreover the filter core that a large amount of entirety is still fallen is also not easy to environmental protection treatment.

Oil rectifier is identical with air filter structure principle, is the filtrating equipment of engine lubrication, oil-fired system, and the impurity in fluid is filtered, and clean fluid prevents that fuel oil from stopping up.Current oil filter for vehicle, for preventing leakage of oil, is to construct one, changes filter cleaner and also needs integral replacing, causes waste.

Summary of the invention:

The object of the utility model, be to provide a kind of Novel filter filter core, its filter element filter cylinder is dismountable connected element alive, changing when filter cleaner not will filter core integral replacing, and only need change filter cylinder, other parts of filter cleaner all can continue to use, and have so both avoided a large amount of wastes, save resource, made again the old filter cylinder of changing be convenient to environmental protection treatment.

For reaching the technological scheme that foregoing invention object takes be: Novel filter filter core, comprises that filter cylinder, net cylinder, button are wrapped in the upper and lower end cap of filter cylinder and net cylinder top and bottom.On described filter cylinder 1, lower end surface respectively has one deck flexible glue layer 5 envelope to wrap up in.Described net cylinder 2 with lower end cap 4 for being fixedly connected with.Described filter cylinder 1, net cylinder 2 are that dismountable living is connected with the upper and lower end cap of its two end, and annular catching groove 14 buttons of upper end cap 3 are wrapped in the top of filter cylinder and net cylinder, and annular catching groove 17 buttons of lower end cap 4 are wrapped in the bottom of filter cylinder and net cylinder.Between upper end cap 3 and net cylinder 2, be provided with and be connected and fixed device.

Described net cylinder 2 also can be provided with interior filter cylinder 9 and Intranet cylinder 12 in it successively.On interior filter cylinder 9, lower end surface respectively has one deck flexible glue layer 5 ' envelope to wrap up in.Intranet cylinder 12 with interior lower end cap 11 for being fixedly connected with.Interior filter cylinder 9 and Intranet cylinder 12 are that dismountable living is connected with the interior upper end cap of its two end, interior lower end cap.Between interior upper end cap 10 and Intranet cylinder 12, be provided with and be connected and fixed device.

The beneficial effect that the utility model produces is:

The upper and lower end face of its filter cylinder of the utility model filter element respectively has one deck flexible glue layer envelope to wrap up in, this flexible glue layer both can close on filter cylinder, lower end surface, make the upper and lower end face of filter cylinder not because paper folding gap leaks gas or leakage of oil, because this flexible glue solidifies, its smooth surface is non-caked afterwards again, thereby make the upper and lower end cap wrapped up in thereon of button can not be bonding with it, make the two become detachable living and connect.Also, because the flexible glue layer of this flexible glue after solidifying has certain elasticity, this can make and detain good seal between the end cap of wrapping up in.By upper, make upper and lower end cover buckle be wrapped in upper and lower two ends of filter cylinder and make the two become dismountable work to be connected to become possibility, also making more renew cartridge only need change filter cylinder becomes possibility.Cause more renew cartridge only need be changed filter cylinder, has just saved ample resources, has saved user cost, has avoided greatly waste, has controlled pollution.
