Abstract
The utility model provides an air filter core, and belongs to the technical field of air filter devices. The structure is that one end of the filter core is provided with a polyurethane PU cover which is glued with the edges of the filter core through pouring. The design of the air filter core cancels a device which is matched with an upper end cap for connecting of an existing air filter core, the upper end cap is changed into the polyurethane PU cover (polyurethane elastic body), the upper end portion of the air filter core does not need further adding sealing rings or sealing strips, the polyurethane PU cover which is fixedly glued and hermetically connected with the air filter core is formed through gluing and pouring polyurethane PU material, and can not drop or generate the phenomenon of leaking air during use process, the air filter core can better enable air to be filtered on appointed filter material normally, thereby reaching better filtering effect, and improving service life of a motor and a combustion engine.
Description
Technical field
The utility model relates to the air filter technical field, specifically a kind of air filtering core.
Background technology
General, traditional air filtering core, upper end cover sealing ring (bar) all adopt glue adhesive class bonding, loosening and the obscission of sealing ring in use often occurs, thereby caused the filter quality of air filtering core and bad, and damage machine too early engine and internal combustion engine.Mainly show: the air filtered is clear, and the dust that suspends in the air is inhaled in the cylinder, will the accelerating piston group and the wearing and tearing of cylinder.Bigger particle enters between piston and the cylinder, can cause serious " scuffing of cylinder bore " phenomenon, and this is particularly serious in the rocky working environment of drying.Air filter is contained in the place ahead of carburetor or air inlet pipe, plays the effect of dust, sand grains in the filtering air, guarantees to enter in the cylinder air of capacity, cleaning.How can a kind of safe and reliable air filtering core of design and use be that core components such as engine are played conclusive protective effect, be present present stage one of important topic to be solved to be arranged.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of air filtering core is provided.
The technical solution of the utility model realizes in the following manner, this air filtering core, and its structure is that the end at filter core is provided with the polyurethane PU lid with the bonding cast in filter core edge.
Filter core is a tubular element.
The beneficial effect that the utility model is compared with prior art produced is:
The design of this air filtering core is the setting that is connected of the existing air filtering core upper end cover of cancellation, and upper end cover is changed into the polyurethane PU lid.The air filtering core upper end no longer needs to add in addition sealing ring or sealing strip; By of the bonding cast of polyurethane PU material in the air filtering core upper end, form with air filtering core fixedly the polyurethane PU that is connected of adhesive seal cover, in use, the polyurethane PU lid of this air filtering core can not come off, gas leak phenomenon can not take place yet, thereby can better make air normally reach better filter effect, improve the service life of engine and internal combustion engine in the filter material filtration of appointment.The air filtering core that the design of this air filtering core can be applicable to the different size of heavy-duty car, engineering machinery, generating set, air compressor and air cleaning facility etc. under the prior art uses.
Polyurethane PU (polyurethane elastomer) can have higher elasticity and intensity, excellent abrasive, oil resistivity, fatigue durability and anti-vibration resistance in the hardness range of broad, have the title of " abrasive rubber ".Though polyurethane elastomer output in polyurethane products is little, polyurethane elastomer has the excellent comprehensive performance, has been widely used in industrial departments such as metallurgy, oil, automobile, ore dressing, water conservancy, weaving, printing, medical treatment, physical culture, grain processing, building.The air filtering core that the design of this air filtering core can be applicable to the different size of heavy-duty car, engineering machinery, generating set, air compressor and air cleaning facility etc. under the prior art uses.
Description of drawings
Accompanying drawing 1 is a main TV structure schematic diagram of the present utility model;
Accompanying drawing 2 is cross-sectional view of the present utility model;
Accompanying drawing 3 is plan structure schematic diagrames of the present utility model.
Mark in the accompanying drawing is represented respectively:
1, filter core, 2, polyurethane PU lid.
The specific embodiment
Below in conjunction with accompanying drawing a kind of air filtering core of the present utility model is done following detailed description the in detail.
Shown in accompanying drawing 1,2,3, a kind of air filtering core of the present utility model, its structure is that the end in tubular element 1 is provided with the polyurethane PU lid 2 with the bonding cast in filter core edge.
This air filtering core is that the end with filter core 1 is immersed in the polyurethane PU mould that high temperature melt is housed when manufacturing, and behind the cooling forming, has directly formed the polyurethane PU lid 2 with filter core end good bond in this end of filter core.
Claims (2)
1, a kind of air filtering core is characterized in that a end at filter core is provided with the polyurethane PU lid with the bonding cast in filter core edge.
2, a kind of air filtering core according to claim 1 is characterized in that filter core is a tubular element.
