The model utility content
The utility model aims to provide a kind of simple in structure, cleaning convenience, and the empty filter of the oil bath type of good filtration effect.
For solving above technical problem, the empty filter of the oil bath type that the utility model provides, comprise sky filter body (1) and foam filter elements (4), it is characterized in that: also comprise lubricating cup (2) and L shaped intake elbow (3), have the air guide channel (1a) of up/down perforation in the described empty filter body (1), the lower end of described intake elbow (3) links to each other with the upper end of empty filter body (1), be provided with the annular chamber (1c) around air guide channel (1a) in the bottom of empty filter body (1), described foam filter elements (4) is contained in the annular chamber (1c), the sidewall of described empty filter body (1) is provided with the waste gas mouth (1b) that is communicated with air guide channel (1a), the air outlet (1d) that is communicated with annular chamber (1c), described lubricating cup (2) are positioned at the below of sky filter body (1) and link to each other with empty filter body (1).
Working procedure: air is entered the air guide channel of sky filter body by the suction port of intake elbow, enter lubricating cup again, because machine oil has adhesive attraction in the lubricating cup, remaining in airborne flying dust is clung by pasta, air is owing to walk in the suction continuation of Carburetor, the fluid particle that machine oil produces then can be entered Carburetor finally by relief opening by foam filter elements institute absorbing and filtering.Simultaneously, the overvoltage gas in the internal-combustion engine cavity also can be through waste gas mouth air inlet air guide channel, and enters Carburetor after filtering.
The upper end outer wall of described empty filter body (1) is provided with hoop tenon (1e), the lower end inwall of described intake elbow (3) is provided with the circumferential groove (3a) corresponding with hoop tenon (1e), after empty filter body (1) was connected together by hoop tenon (1e) and circumferential groove (3a) with intake elbow (3), circumferential groove (3a) can be around the axis rotation of air guide channel (1a); Rotatable intake grill is selected the good air intake surface of air quality, guarantees air intake and the air intake quality.
Further, two limiting boards (5) are housed also in the described annular chamber (1c), described limiting board has air passing hole on (5), and it is spacing to foam filter elements (4) that two limiting boards (5) lay respectively at the both sides up and down of foam filter elements (4).
Bottom in the described lubricating cup (2) has extended upward vertical clapboard (2a), and vertical clapboard (2a) is one-body molded with lubricating cup (2), can increase the bulk strength of lubricating cup on the one hand, also can play the effect of oil level indication on the other hand.
Beneficial effect: during cleaning, only lubricating cup need be taken off, just can take out foam filter elements and clean, air-guiding aisle is long, the power of irritating under the wind is bigger, has characteristics such as simple in structure, that design is ingenious, cleaning is convenient, and can filter out airborne impurity and dust well.
