Abstract
The utility model relates to a filter element assembly of an air filter. The filter element assembly comprises a paper element, an upper end cover and a lower end cover. The paper element is respectively connected with the upper end cover and the lower end cover by welding. The filter element assembly has the advantages that the use of the paper filter element which is singly in the PU (polyurethane) foam structure in the air filter is avoided, the paper element and plastic welding technology are widely applied to the air filters, and forming cycle of products is shortened due to the use of welding technology.
Description
Technical field
The utility model relates to a kind of air-strainer, relates in particular to the element kit in this air-strainer.
Background technique
Air-strainer is the device that a kind of air purifies, it is comprised of air filter suction tude, air filter body assembly structure, air filter steam outlet pipe, air filter body assembly structure comprises upper shell assembly, lower shell body assembly and element kit, element kit with rational structural configuration in housing.Being connected with engine intake for filtering atmosphere by the air filter steam outlet pipe has various foreign matters, such as dust, sand grains etc.If directly enter motor without the air-strainer filtration, various foreign matters will speed up the wearing and tearing of motor, thereby reduce the working life of motor.Sometimes tire can take up slungshot, in case enter motor, just can make motor badly damaged.
As shown in Figure 1, existing element kit adopts paper filter core, and paper filter core comprises filter paper 1 and polyurethane (Polyurethane, PU) foaming structure 2, and polyurethane foam structure 2 pressurized in upper shell assembly and lower shell body assembly plays sealing effect.
The element kit that how to design a kind of better air-strainer is that the technician will consider.
Summary of the invention
The utility model technical issues that need to address have provided a kind of element kit of air-strainer, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: refill; Also comprise: upper end cap and lower end cap; Described refill respectively with upper end cap and lower end cap by being welded to connect.
Compared with prior art, the beneficial effects of the utility model are: avoid adopting the single use polyurethane of paper filter core (PU) foaming structure in the air-strainer, refill and TECHNOLOGY OF WELDING PLASTICS are widely used in air-strainer; Use in addition welding technique to reduce the molding cycle of product.
Description of drawings
Fig. 1 is the element kit structural representation of existing air-strainer.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is C place enlarged view among Fig. 2.
Fig. 4 is for adopting element kit and the upper and lower casing assembly connecting structure figure of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
By Fig. 2, Fig. 3 as seen: the element kit of air-strainer of the present utility model comprises: refill 32; Also comprise: upper end cap 31 and lower end cap 33; Described refill 32 respectively with upper end cap 31 and lower end cap 33 by being welded to connect.
Described refill 32 fuses into the distance of upper end cap 31 and lower end cap 33 respectively between 1.4mm-1.6mm.
The element kit of described air-strainer be shaped as cylindrical body.
As seen from Figure 4: element kit 22 is contained on the lower shell body 23, by screw upper shell 21 is installed to the lower shell body assembly, finishes the general assembly of air-strainer body.
The element kit of the utility model air-strainer has avoided that paper filter core uses single processing mode in the air-strainer, and the utility model filter core and original PU foaming filter core are than the process-cycle of having reduced filter core.
Claims (3)
1. the element kit of an air-strainer comprises: refill; Characterized by further comprising: upper end cap and lower end cap; Described refill respectively with upper end cap and lower end cap by being welded to connect.
