An oil bath air filter with an adjustable structure

Abstract

This utility model relates to the field of air filter technology and discloses an oil bath air filter with an adjustable structure, including a housing and an oil reservoir. An air guide pipe is fixedly installed on the housing. This oil bath air filter with an adjustable structure is configured by the cooperation of the oil reservoir, air guide pipe, diverter plate, inner pipe, air inlet cover, partition plate, filter element, air outlet, partition plate, partition ring, first threaded hole, first fastening bolt, second threaded hole, and second fastening bolt. During use, the air is diverted by the diverter plate and inner pipe inside the air guide pipe. Then, by loosening the second fastening bolt and rotating the oil reservoir according to the indicator strip, the amount of air flowing into each oil cell through the air guide pipe is adjusted, avoiding uneven contact between air and oil. The air is then filtered through the filter element and flows out through the air outlet, thus allowing the intake air to enter the air filter more evenly for filtration, effectively improving filtration efficiency and effect.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-2This utility model provides a technical solution: it includes a housing 1 and an oil storage bottom shell 2. A vent pipe 3 is fixedly installed on the housing 1. An inner pipe 5 is fixedly installed on the vent pipe 3 through a diverter plate 4. An air inlet cap 6 is sleeved on one end of the vent pipe 3. A partition plate 7 is fixedly installed inside the housing 1. A filter element 8 is installed inside the housing 1 below the partition plate 7. An air outlet 9 is provided at the top of the outer wall of the housing 1. The bottom of the housing 1 is inserted into the oil storage bottom shell 2. A partition plate 10 is provided on the inner bottom wall of the oil storage bottom shell 2. A partition ring 11 is installed on the top of the partition plate 10. First threaded holes 12 are provided on the outer wall surfaces of both the vent pipe 3 and the air inlet cap 6.
