The model utility content
The utility model aims to provide a kind of empty filter of secondary filter, and dust in air is had filtering effect preferably, and simple in structure, cleaning convenience.
For solving above technical problem, the empty filter of the secondary filter that the utility model provides, comprise sky filter loam cake (1), empty filter following (2) and base (3), described empty filter loam cake (1) and empty filter following (2) snap together and constitute the empty filter main body that has four sides, described base (3) is positioned at sky filter main body below, base (3) is provided with relief opening (3a), center-pole (3a) on the base (3) passes sky filter main body from bottom to top, and in conjunction with first nut (4) with empty filter loam cake (1), empty filter following (2) and base (3) are locked together, key is: the secondary filter papery filter core (8) that is provided with ring in described empty filter main body, on secondary filter papery filter core (8), following two ends are respectively arranged with filter core pressing plate (5), described secondary filter papery filter core (8) and filter core pressing plate (5) are sleeved on the center-pole (3b), and by second nut (6) locking, leave the gap between the outer wall of described secondary filter papery filter core (8) and the inwall of empty filter main body, the internal diameter of secondary filter papery filter core (8) is greater than the diameter of center-pole (3b), bottom at empty filter following (2) has via hole (2a), described via hole (2a) is provided with relief opening (3a) connection with inner chamber and the base (3) of secondary filter papery filter core (8), the outside of described empty filter loam cake (1) is installed with L shaped air inlet baffle plate (7), described air inlet baffle plate (7) covers wherein two sides of empty filter main body, have inlet hole (7b) in the two side of air inlet baffle plate (7) (7a), be provided with first filter foam (9) in first cavity (A) that air inlet baffle plate (7) and empty filter loam cake (1) surround, described first cavity (A) communicates with the inner chamber of empty filter main body.
Be preferably, described second nut (6) is wing nut, and manually rotation need be by instrument, and is easy to operate.
Further, the surface of described secondary filter papery filter core (8) is coated with one deck removable filter foam, selects the different filter foam of density, the air inflow that can regulate secondary filter papery filter core.
Relief opening position on the base is provided with mounting flange, links to each other with the suction port of Carburetor by mounting flange.Working procedure: under the suction of Carburetor, air enters in first cavity via the inlet hole of L shaped air inlet baffle plate, first filtration through first filter foam, can filter out most of flying dust, enter the inner chamber of sky filter main body then, the two ends up and down of secondary filter papery filter core are sealed by the filter core pressing plate, air can only enter the inner chamber of secondary filter papery filter core from the sidewall of secondary filter papery filter core, filtration again through secondary filter papery filter core, clean air enters base by the via hole of following bottom of empty filter afterwards, enters Carburetor through relief opening again.
Beneficial effect: adopt the mode of twice filtration that air is filtered, the dust in the filtered air better is for internal-combustion engine provides cleaner air for burning; During cleaning, only first nut need be screwed out, just empty filter loam cake and following of empty filter can be separated, have characteristics such as simple in structure, that cleaning is convenient.
