Specific embodiment
Below in conjunction with the accompanying drawings, a specific embodiment of the present invention is described in detail, it is to be understood that of the invention
Protection domain do not limited by specific embodiment.It is to be appreciated that mentioned in the implementation below of the present invention
" on ", D score, "left", "right", " front " and " reverse side " on the basis of the direction shown in each figure, these are used for limiting direction
Word be intended merely to facilitate explanation, do not represent the restriction to concrete technical scheme of the present invention.
The air filter of engine of the present invention passes through, the sealing shroud for being equipped with circular arc spigot surface structure using sealing cone double wall
Pipe and filter core locating support, it is achieved that filter core automatic centering is positioned, and facilitates the insertion of main filter core and safety filter element, to greatest extent
Facilitate user installation, greatly reduce labour intensity, preventing error is installed；And prevent filter core PU materials and isolated damage, while save
Rubber sealing structure has been omited, sealing effectiveness has been improve.
As depicted in figs. 1 and 2, the concrete structure of the air filter of engine includes：Cylinder and the filter in the cylinder
Core assembly.Wherein, cylinder includes：Cylinder body 11, and the ash-pan 13 of 11 bottom of cylinder body, pine is located at by the lid of hoop 12
Open loop hoop 12, opens ash-pan 13, you can by element kit in cylinder body 11.
As shown in Figure 3 and Figure 4, the left end central authorities and top of cylinder body 11 offer air inlet 14, gas outlet 15 respectively,
The inner port of air inlet 14 is welded with sealing sleeve pipe 16, and the lower inner wall of cylinder body 11 is welded with filter core locating support 17.Such as
Shown in Fig. 3 and Fig. 5, the double-wall structure of the side wall of sealing sleeve pipe 16 for doubling, its inner and outer wall are into air inlet 14
The sealing cone structure of receipts, its end face for connecting inner and outer wall is circular arc spigot surface, stretches moulding using A3 steel plates cold punching, its
Axis is overlapped with the center line of cylinder body 11.
Filter core locating support 17 is using 4 round steel materials of Φ and Zincing passivation is processed, and which is two, is respectively separated and is welded on cylinder
On the inwall circumference of body body 11, and there is upper arcuate to center portion, upper arcuate is to the center of circle of center portion in cylinder body 11
On axis, i.e., also on the axis of sealing sleeve pipe, and the main filter of the radius of the filter core locating support 17 and element kit
The outer section radius of core are equal, after main filter core is placed in cylinder, the axis of main filter core will automatically with cylinder and sealing sleeve pipe
Axis overlaps, and realizes that automatic centering is positioned.
Element kit includes：Main filter core 21 and safety filter element 22, two filter cores adopt filter core for PU encapsulants.Assembling
When, hoop 12 is unclamped, ash-pan 13 is opened, first safety filter element 22 is nested in main filter core 21, then two filter cores are entered cylinder simultaneously
