Abstract
The invention provides a filter core end cover which comprises an end cover body and a through hole arranged on the end cover body, wherein a boss is arranged on the end cover body, the end cover body and the boss from an integrated structure, the through hole penetrates through the end cover body and the boss, and the boss is an elastic boss capable of elastically springing back when being pressed in the axial direction of the through hole. The invention further provides a filter core which comprises a filter core body, wherein the filter core end cover is respectively arranged at the upper end and the lower end of the filter core body. The filter core end cover and the filter core are simple in structure, convenient in process and good in sealing effect.
Description
Technical field
The present invention relates to a kind of filter element, be specifically related to a kind of end cover of filter element and filter core.
Background technology
Filter core in the market is mainly by upper and lower end cap, refill, central tube, the nonwoven sealing ring, the special-shaped circle of rubber waits composition, wherein product end cap mostly the mode of the direct ultrasonic bonding nonwoven of the upper and lower end cap of employing seal washer reach sealing effectiveness; Perhaps nonwoven is placed directly on the injection mold, adopts the mode of single injection-molded to reach sealing effectiveness; Or be to reach sealing effectiveness by the mode that sealing ring is installed.
Application number is that 200810121623.9 Chinese invention patent discloses a kind of filter element, and end cap seal circle 5 adopts nonwoven cloth materials to make, and nonwoven cloth material adopts the ultrasonic bonding mode to be welded on the end cap body 1, as illustrated in fig. 1 and 2.There is following problem in the bonding nonwoven of this kind mode: 1, end cap by injection moulding be accomplished to the weldering nonwoven divide two processes to finish, efficient is not high; 2, there is the unstability of equipment in ultrasonic bonding, so that the nonwoven of welding is insecure or occur that intensity is excessive to cause nonwoven welding damaged, not attractive in appearance in appearance; Such as not prison welding, filter core the situation that nonwoven comes off can occur in actual use, as weld excessively, the situation that nonwoven burns can appear, closely cause the damaged obscission of nonwoven, these two kinds of phenomenons cause comes off and nonwoven is fallen into cause lubricant passage way to stop up in the filter block, thereby affects the normal operation of engine; 3, the fiber fines on the nonwoven can form hydro-planing under the vibration of ultrasonic wave effect during ultrasonic bonding nonwoven, pollutes the environment of operationlocation.
And application number is 201010601716.9 the disclosed filter element of Chinese invention patent, and end cap seal circle 5 adopts nonwoven cloth material to make, and nonwoven is embedded in the mould, is shaped through matched moulds injection moulding and end cap body 1, shown in Fig. 3 and 4.There is following problem in the bonding nonwoven of this kind mode: 1, have the nonwoven cutting action, nonwoven needs first cutting, again injection moulding, and operation is loaded down with trivial details; 2, need nonwoven cloth material; 3, non-woven fabrics fiber is easily floating, forms to pollute.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of end cover of filter element and filter core, and simple in structure, technique makes things convenient for, good sealing effect.
For solving above-mentioned existing technical problem, the present invention adopts following scheme: a kind of end cover of filter element, comprise end cap body and the through hole that is located on the end cap body, described end cap body is provided with boss, described end cap body and boss are structure as a whole, described through hole runs through end cap body and boss, but the elasticity boss of described boss elastic recovery for along axially the pressing of through hole the time.Boss is flexible, cooperates when installing with assembly closely, has the function of similar sealing ring, can play good sealing function.
As preferably, described through hole is circular hole, and described boss is the cylinder of hollow.Structure is more reasonable.
As preferably, described boss is provided with snap ring, and described snap ring internal diameter is positioned at the internal diameter at place, two ends less than boss, and described snap ring internal diameter is positioned at the external diameter at place, two ends less than boss.The boss indent forms a snap ring, and assembling is simple, and good seal performance has certain elasticity when making boss along axially the pressing of through hole.
As preferably, described end cap body and the one-shot forming of boss integrated injection molding.Need not other sealing mediums such as nonwoven or sealing ring.
A kind of filter core comprises the filter core body, and described filter core body is provided with above-mentioned end cover of filter element in two ends up and down.
Beneficial effect:
A kind of end cover of filter element and filter core that the present invention adopts technique scheme to provide, simple in structure, technique makes things convenient for, good sealing effect.

The specific embodiment
As shown in Figs. 5 to 7, a kind of end cover of filter element, comprise end cap body 1 and the through hole 4 that is located on the end cap body 1, described end cap body 1 is provided with boss 2, described end cap body 1 is structure as a whole with boss 2, described through hole 4 runs through end cap body 1 and boss 2, but the elasticity boss of described boss 2 elastic recovery for along axially the pressing of through hole 4 time.Described through hole 4 is circular hole, and described boss 2 is the cylinder of hollow.Described boss 2 is provided with snap ring 3, and described snap ring 3 internal diameters are positioned at the internal diameter at place, two ends less than boss 2, and described snap ring 3 internal diameters are positioned at the external diameter at place, two ends less than boss 2.Described end cap body 1 and boss 2 integrated injection molding one-shot formings.
A kind of filter core comprises filter core body 6, and described filter core body is provided with above-mentioned end cover of filter element in two ends about in the of 6.
In this structure, described boss 2 is identical with end cap body 1 material, and the injection moulding one-shot forming is easy, and wall was thin when boss 2 was made, wall is soft, because boss 2 walls are thin, wall is soft, thereby has elasticity when boss 2 is pressed, and can cooperate tight when installing with assembly.The present invention has the following advantages: 1, reduce accessory, need not nonwoven sealing ring and special-shaped circle and wait sealing medium; 2, operation is few, and the injection moulding one-shot forming can be finished, and has improved production efficiency; 3, reduce cost, fully pollution-free.
