Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the filter comprises a shell body 1, a clamping tenon 2, a clamping block 3, a cover body 4, a filter part 5, a sealing gasket 6, a sealing strip 7, a filter piece 8, a filter screen 9, a guide plate 10, a fixing plate 11, an air outlet 12, a dust outlet 13, an air inlet 14, a baffle plate 15, an upper cover 16 and a lower cover 17.

The embodiment is basically as shown in the attached figures 1 to 4: a coarse filter with a spiral air passage comprises a shell and a filtering part 5, wherein the shell is in a round table shape, an air inlet 14 is formed in the upper end of the shell, and the air inlet 14 is arranged along the tangential direction of the shell. The lower end of the shell is provided with an air outlet 12, the central line of the air outlet 12 is collinear with the axis of the shell, and the air outlet 12 is provided with external threads. The provision of external threads facilitates the attachment of the strainer to other structures (such as a primary air filter or air inlet tube). A guide plate 10 is arranged on the inner wall of the shell, the guide plate 10 is spiral, and the upper end of the guide plate 10 is positioned at an air inlet 14; the end of the shell close to the air outlet 12 is provided with a dust outlet 13, the lower end of the guide plate 10 is positioned at the dust outlet 13, and the guide plate 10 and the inner wall of the shell form a spiral air passage.

Referring to fig. 3 and 4, the casing includes a casing body 1 and a cover 4, the casing body 1 and the cover 4 are detachably connected, the air deflectors are respectively disposed on inner walls of the casing body 1 and the cover 4, and the air deflectors on the inner walls of the casing body 1 and the cover 4 can be combined into the spiral air deflector 10. The outer wall of the shell body 1 is provided with a clamping tenon 2, the clamping tenon 2 and the shell body 1 are integrally formed, the cover body 4 is provided with a clamping block 3 clamped with the clamping tenon 2, and the clamping block 3 and the cover body 4 are integrally formed. The number of the clamping tenons 2 and the number of the clamping blocks 3 are multiple, in the embodiment, the number of the clamping tenons 2 and the number of the clamping blocks 3 are three, and the three clamping tenons 2 are respectively positioned at the top end of the shell body 1 and at two sides of the side wall; the three clamping blocks 3 are respectively positioned at the top end of the cover body 4 and at two sides of the side wall. When the cover is used, the clamping blocks 3 are respectively clamped into the clamping tenons 2, and then the shell body 1 and the cover body 4 can be connected together. In this embodiment, the three tenons 2 and the three clamping blocks 3 form a triangular shape, so that the connection between the housing body 1 and the cover 4 is more stable. The lower end of the shell body 1 is provided with a baffle 15, the baffle and the shell body 1 are integrally formed, and the baffle 15 is positioned at the dust outlet 13.

Referring to fig. 2 and 3, the filter portion 5 includes a filter member 8, a filter net 9, an upper cover 16, and a lower cover 17, and the filter member 8 in this embodiment may be made of foam. Filter 8 and be cylindric, filter screen 9 sets up in filtering 8 inner walls, upper cover 16 with filter 8 upper end rigid coupling, lower cover 17 with filter 8 lower extreme rigid coupling, lower cover 17 middle part is opened has the through-hole, filter 8's inner chamber and pass through-hole and gas outlet 12 intercommunication. A fixing plate 11 is integrally formed at the upper end of the inner wall of the shell body 1, and the fixing plate 11 is clamped with an upper cover 16.

The specific implementation process is as follows: when the coarse filter of this scheme of adoption, the air enters into the space of casing inside from air inlet 14. Because the air inlet 14 is arranged along the tangential direction of the housing, larger particles of dust in the air will flow along the air deflector 10 and be discharged from the dust outlet 13 after entering the housing. The upper and lower ends of the filter element 8 are closed by the upper and

lower covers

16, 17, and air can only enter the filter element 8 from the side wall of the filter element 8 and can be discharged from the air outlet 12 through the through hole into the next stage of filter mechanism or into the carburetor. And the air gets into from the lateral wall and filters 8 in-process, filters 8 and can filter the air, can be with dust and the air separation in the air like this, reaches the effect to air primary filter. The baffle 15 can block the dust moving to the dust outlet 13 along the deflector 10, so that the dust can only be discharged along the dust outlet 13 and can not be left in the housing. The coarse filter of this embodiment can avoid a large amount of dust to pile up in the casing, influences subsequent admitting air. The housing body 1 and the cover 4 may be disassembled to replace the filter part 5 with a new one after the filter part 5 is used for a certain period of time.
