Abstract

The utility model relates to a combined type filter core of cleaner which belongs to the field of filter and mainly solves the problem that the colloid and the tiny carbon granules in the machine oil can not be filtered out because the filtration pore of a one-stage filter core is too big. A coarse filter core(1) with bigger filtration pores which is the superior layer and a fine filter core with smaller filtration pores which is arranged below are integrated to be coaxial. The combination between the two is made by a tight binding with a binding layer(5) to be air-proof or by binding with each other with matched end caps which have a convexity or a concave surface by a sealing gasket(6) to be air-proof. The advantage of the utility model is that the structure is simple, the production is easy, the middle coarse filter core and the fine filter core both function in the filtration, the filtered machine oil is directly used to lubricate, the amount of spare oil for power equipment can be guaranteed, and the colloid and tiny carbon granules in the machine oil can be effectively filtered out to prolong the service life of the machine oil.

Description

The combined type filter core of cleaner

Technical field

The utility model belongs to the cleaner field, relates to a kind of cleaner combined type filter core.

Background technology

In the prior art, the filter element of the filter core of cleaner all is the so-called single-stage filter core with same size filtering holes, guarantee to use oil mass for reducing the machine oil resistance, filter opening can not be too small, therefore, all can not filtering for colloid contained in the used machine oil of automobile engine roughly the same, small carbon granules, thus machine oil is aging easily.For prolonging liquid being filtered, especially service life of machine oil, the cleaner that has adopts so-called twin-stage filter core, the twin-stage filter core is by mutual independence and lay respectively at coarse filter element (filtering holes the is bigger) cleaner on the main oil gallery and fine filtering core (filtering holes the is less) cleaner that is positioned on the backflow oil duct is formed, machine oil all filters by coarse filter element generally speaking, have only when the oil pump amount of buying oil is big, after excessive part machine oil just filters by the fine filtering core on the backflow oil duct, oil return storage tank again, therefore, the fine filtering core is that batch (-type) works, and the elder generation of the machine oil after it filters oil return storage tank, with by filtering and the machine oil that is used for after lubricated mixes the back use on the main oil gallery through coarse filter element, complex structure not only, and fine filtering core batch (-type) works, and its machine oil after filtering directly do not go to be used for lubricated but first oil return storage tank, so its poor effect.

Summary of the invention

The technical problem that solves:

A kind of combined type filter core is provided, thick in same cleaner, fine filtering core is combined into one, can overcome the deficiencies in the prior art, simple in structure, the all common always filtration of thick in the use, fine filtering core promptly directly goes after machine oil is filtered to be used to lubricate, and can guarantee the power-equipment oil mass, colloid, small carbon granules in the filtering machine oil effectively again, thus service life of machine oil prolonged.

The technical scheme that adopts:

The combined type filter core of cleaner has coarse filter element 1, fine filtering core 2, top cover 7, bottom 8 and corresponding accessory, it is characterized in that: coarse filter element 1 is descending at last, fine filtering core 2, and the two coaxial-type links together and is combined into one.

Beneficial effect:

The combined type filter core of cleaner, simple in structure, easily manufacture, the all common always filtration of thick in the use, fine filtering core, after being filtered, promptly directly goes in machine oil to be used to lubricate, can guarantee the power-equipment oil mass, colloid, the small carbon granules in the filtering machine oil effectively again, thus prolong service life of machine oil.

The specific embodiment

Further explanation in detail in conjunction with the accompanying drawings; Arrow is depicted as the flow direction of liquid among the figure;

Shown in Fig. 1～4, coarse filter element 1 is combined into one with fine filtering core 2 sealed linking together, have following two kinds of frame modes: a kind of be its filter element of upper port of the lower port of coarse filter element 1 shown in Fig. 3 (a) and supporting fine filtering core 2 directly by adhesive linkage 5 mutual sealed bonding together, or the upper end cover 4 that has on the upper port of the bottom end cover 3 that has on the lower port as Fig. 3 (b) coarse filter element 1 and fine filtering core 2 is by adhesive linkage 5 mutual sealed bonding together; Another kind is as shown in Figure 4, has convex bottom end cover 3 on the lower port of coarse filter element 1, has the matrix upper end cover 4 supporting with convex bottom end cover 5 on the upper port of fine filtering core 2, and the two contacts by sealing gasket 6 mutual tightening seal formulas.Can certainly be matrix bottom end cover 3 supporting convex upper end covers 4.

Top cover 7 is positioned on the upper port of coarse filter element 1, and bottom 8 is positioned on the lower port of fine filtering core 2, ordinary single-stage filter core roughly the same when using or changing, and the filter case of packing into both can be in place easily and fixing; The combined type filter core can be applicable to difform filter case on demand.

Claims

1, the combined type filter core of cleaner has coarse filter element (1), fine filtering core (2), top cover (7), bottom (8) and corresponding accessory, it is characterized in that: coarse filter element (1) is descending at last, fine filtering core (2), and the two coaxial-type links together and is combined into one.

2, the combined type filter core of cleaner according to claim 1, it is characterized in that: coarse filter element (1) is combined into one with sealed the linking together of fine filtering core (2), have following two kinds of frame modes: a kind of be its filter element of upper port of the lower port of coarse filter element (1) and supporting fine filtering core directly by adhesive linkage (5) sealed bonding together mutually, or the upper end cover (4) that has on the upper port of the bottom end cover (3) that has on the lower port of coarse filter element (1) and fine filtering core (2) is by mutual sealed the bonding together of adhesive linkage (5); Another kind is, has convex bottom end cover (3) on the lower port of coarse filter element (1), has the matrix upper end cover (4) supporting with convex bottom end cover (5) on the upper port of fine filtering core (2), the two by sealing gasket (6) mutually the tightening seal formula contact.
