Abstract

The utility model discloses a detachable and assembling air filter element. A skeleton of the air filter element which is provided with a filtering hole on the wall is provided with a filter paper layer in a winding way, and a spongy layer is arranged outside the filter paper. Both ends of the skeleton are respectively provided with a circular ring-shaped pressing plate and an iron sheet gland, and the end part of the filter paper is arranged between the circular ring-shaped pressing plate and the iron sheet gland. The inner walls of both ends of the skeleton are respectively provided with a convex block, and the convex blocks of the skeleton are arranged in a recess of the iron sheet gland. The filter paper is clamped between an arc-shaped ring groove of the skeleton and a hole of the circular ring-shaped pressing plate. The utility model can be cleaned in a disassembling way and utilized again after the utility model is assembled. The utility model is favorable to environment protection. The utility model is suitable for diesel engines and gasoline engines.

Description

Dismantled and assembled air filtering core

The utility model relates to a kind of dismantled and assembled air filtering core, is used for diesel engine and petrol engine.

Air filtering core all is housed in diesel engine on automobile, tractor and the engineering vehicle or the petrol engine, this air filtering core is lost filter capacity by the foul obstruction easily and can't use, the filter core that need more renew, it is the easily damaged parts on the motor, and air filtering core is made up of the inside and outside thin wire filter screen of cylindrical shape, filter paper and iron sheet lid; Between inside and outside thin wire filter screen, install and be folded into columnar filter paper, the iron sheet lid that has filtering hole is bonding the connection with inside and outside thin wire filter screen (filter paper), inhale flat during this filter core uses easily, after being blocked, filter core can't take cleaning apart, the air filtering core that has stopped up is easy to clean not, often abandons in the street and road is other that environment is polluted.In fact the inside and outside filter screen and the iron sheet lid of the air filtering core that has been stopped up by foul are still intact, making waste product handles very unfortunate, there is the automobile more than ten million in China, the transportation equipment of especially various heavy types, all use high-horsepower diesel engine as truck, engineering truck, locomotive, loader and steamer etc., the specification of used air filtering core is also big, and hundred yuan in tens of units to of its price will produce very big economic benefit so make a kind of filter core of dismantled and assembled cleaning.

The purpose of this utility model is to design a kind of dismantled and assembled air filtering core of being made up of skeleton, filter paper, sponge, ring pressing plate and iron sheet gland for overcoming existing deficiency with air filtering core, is used by the washable cleaning of air filtering core that foul stops up again.

The utility model content, a kind of dismantled and assembled air filtering core, it is characterized in that: wall is provided with on the air filtering core skeleton of filtering hole and adorns filter paper layers, filter paper peripheral hardware sponge layer, ring pressing plate and iron sheet gland are respectively established in the two ends of skeleton, the filter paper end is loaded between ring pressing plate and the iron sheet gland, respectively be provided with projection on the inwall at skeleton two ends, the outer wall of iron sheet gland is provided with the groove that snaps in for the skeleton projection, the projection of skeleton is stuck in the groove of iron sheet gland and makes sponge, the ring pressing plate, filter paper and iron sheet gland compress, respectively be provided with arc-shaped ring groove on the outer wall at skeleton two ends, the ring plate hole is a convex along the cross section of thickness direction, and filter paper is sandwiched between the arc-shaped ring groove and ring plate hole at skeleton two ends.

The skeleton of dismantled and assembled air filtering core and being connected also of iron sheet gland can be designed to the screw linkage structure, make tapped hole on the ring pressing plate, and iron sheet gland, filter paper and ring pressing plate are connected by screw and compress, and tighten up through screw between iron sheet lid and skeleton.

The utlity model has following good effect:

1. air filtering core is an easily damaged parts, just pull down after used air filtering core is stopped up by foul and renew, old just can not use again, and the utility model can through unpicking and washing cleaning change then new filter paper through the assembling after can use again, not only reduced material damage, can also save a large amount of expenses, an automobile approximately can be saved 200 yuan every year, China has more than 1,000 ten thousand automobiles and machinery and other traffic tool of bavin, petrol engine is housed, and just can save 2,000,000,000 yuan in 1 year, and economic implications is very big.

2. the bigger sponge of the sponge of dismantled and assembled air filtering core employing density is done the filter body and is served as a contrast with filter paper, and its advantage is that air inflow has increased, and has improved the degree of purity of air inlet, and the difficult quilt of filter core is inhaled flat damage ring in the work.

3. because the washable cleaning of dismantled and assembled air filtering core usefulness again, the phenomenon that abandons air filtering core everywhere can be overcome, and is beneficial to environmental protection.

Fig. 1 is the utility model embodiment 1 schematic representation;

Fig. 2 is the utility model embodiment 2 schematic representation;

Fig. 3 is embodiment 1 system decomposition figure;

Fig. 4 is embodiment 2 system decomposition figure.

Further specify the utility model below in conjunction with drawings and Examples.

Embodiment 1, and please referring to Fig. 1, Fig. 2, dismantled and assembled air filtering core is by skeleton 1, filter paper 3, and sponge 4, ring pressing plate 5 and iron sheet gland 6 are formed.Skeleton is a moulding, wall is provided with the hole slot 2 of ventilation, two ends, skeleton hole are provided with projection 7, four projections of every end, and evenly distribute along circumference, iron sheet gland 6 is a sheet metal part, the thickness of iron sheet is 0.2-0.4mm, establish groove 8 on the cylindrical part outer wall of iron sheet gland, groove is four and evenly distributes along circumference; At first filter paper is installed around on the cylindrical of skeleton, filter paper is adorned sponge outward, load onto the ring pressing plate at an end cover of skeleton again, the end of filter paper by drawing and stretch out in the ring plate hole, filter paper is sandwiched between the arc-shaped ring groove and ring plate hole at skeleton two ends, adorn the iron sheet gland then, attention will make the groove of iron sheet gland corresponding with the projection on the skeleton, again by depressing the iron sheet gland, so that the groove of the projection of skeleton and iron sheet gland is buckled together, this structure also is called buckle structure; The other end is same as described above.

Embodiment 2, please referring to Fig. 3, Fig. 4, the buckle structure that present embodiment replaces the groove of skeleton projection in the example 1 and iron sheet gland to match with the screw linkage structure, be suitable for the height filter core more flat with diameter ratio, the two ends of skeleton respectively are provided with tapped hole, and tapped hole quantity is four and evenly distributes along circumference; The cylindrical part of iron sheet gland is provided with four screw via holes and uniform, and the integrated disc portions of iron sheet gland is drilled with four screw via holes and uniform; Be shaped on four tapped holes corresponding on the ring pressing plate with the screw via hole of iron sheet gland, after filter paper, sponge and ring pressing plate are loaded on the skeleton, the end of filter paper by drawing in the ring plate hole and launching, refill the iron sheet gland, follow cartridge screw 9, skeleton and iron sheet gland are fixed, refilled screw 10, ring pressing plate, filter paper and iron sheet gland are tightened up.
