Description
Technical Field
The utility model relates to the field of internal combustion engines, in particular to an oil bath type air inlet filtering device for a multi-stage filtering air filter of an internal combustion engine.
Background
In the traditional technology, the multi-stage filtering air filter of the internal combustion engine generally adopts two modes, one mode is to adopt a sponge filter element or a paper filter element to filter dust in air, and the other mode is to use an oil cup to enable impurities in the air to be in contact with oil products for oil bath type filtering. The first air filter is simple in structure, poor in filtering effect and incapable of being used in environments with much dust, large moisture and the like, and the second air filter can filter more dust, but the filtering effect of the second air filter is still to be improved along with continuous improvement of product requirements.
The internal combustion engine works in an environment with much dust, the internal combustion engine is not fully combusted due to poor air inlet quality, and the carbon deposition of a spark plug is serious; the fuel is directly discharged along with the waste gas without being fully combusted, so that the exhaust pollutants exceed the standard and the oil consumption is increased; moreover, poor cleanliness can also lead to abnormal cylinder wear and reduce the life of the engine. Therefore, there is an urgent need for an oil bath type filter device for a multistage filtering air filter of an internal combustion engine, which has a better filtering effect.
Disclosure of Invention
The utility model aims to provide an oil bath type air inlet filtering device for a multistage filtering air filter of an internal combustion engine, which is suitable for the multistage filtering air filter containing an oil bath type and can be popularized and applied to various internal combustion engines.
The technical scheme of the utility model is as follows: an oil bath type air inlet filtering device for a multi-stage filtering air filter of an internal combustion engine comprises an oil cup, an oil cup adapter and a sealing ring, and is characterized in that the oil cup adapter is arranged between the oil cup and the air filter, the sealing ring is arranged on the oil cup adapter, the oil cup adapter and the oil cup are sealed through the sealing ring, the oil cup adapter is provided with a submergence blocking oil lip and a filter element bracket, the submergence blocking oil lip and the oil cup form a filtering buffer chamber, air repeatedly contacts with an oil film in the filtering buffer chamber, and enters the internal combustion engine after being fully filtered. The filter element bracket arranged on the oil cup adapter plays a role in supporting and compressing the filter element of the air filter, and the filter element bracket can support at least one filter element.
The utility model has the beneficial effects that: the utility model has simple structure and wide application range, effectively solves the problems of excessive exhaust pollutants and high oil consumption caused by more intake impurities and insufficient fuel combustion, reduces the abrasion of the cylinder and prolongs the service life of the internal combustion engine.
The accompanying drawings, which are included to provide a further understanding of the utility model and are incorporated in and constitute a part of this specification, illustrate embodiment(s) of the utility model and together with the description serve to explain the utility model without limiting the utility model.
Drawings
Fig. 1 is a schematic view of the internal structure of the present invention.
The numbering in the drawings illustrates:
1. an air filter body; 2. a filter element; 3. a seal ring; 4. a filtration buffer chamber; 5. a gas collecting pipe; 6. an oil retaining lip is submerged; 7. an oil cup; 8. an oil cup adaptor; 9. a filter cartridge holder.
It should be noted that, in the following paragraphs, possible directional terms including, but not limited to, "upper, lower, left, right, front, rear, inner and outer" etc. are used for convenience only to facilitate those skilled in the art to better understand the technical solution of the present invention, and should not be construed as limiting the scope or technical solution of the present invention.
It should also be noted that the terms "mounted," "assembled," "connected," and "connected" are to be construed broadly unless otherwise specifically indicated and limited. For example, the connection can be fixed connection or detachable connection; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the creation of the present invention can be understood by those skilled in the art according to specific situations.
Detailed Description
The utility model will be further explained with reference to the drawings.
As shown in figure 1, the oil bath type air inlet filter device for the multi-stage filtering air filter of the internal combustion engine comprises an oil cup 7, an oil cup adapter 8 and a sealing ring 3, wherein the oil cup adapter 8 is installed between the oil cup 7 and an air filter body 1, the sealing ring 3 is installed on the oil cup adapter 8, the oil cup adapter 8 and the oil cup 7 are sealed through the sealing ring 3, the oil cup adapter 8 is provided with a diving baffle oil lip 6 and a filter element bracket 9, and the diving baffle oil lip 6 and the oil cup 7 form a filtering buffer chamber 4. The filter element bracket 9 is a sheet-shaped support plate arranged on the oil cup adapter 8, the number of the support plates is at least 3, and the filter element bracket 9 plays a role in supporting and compressing the filter element 2.
Specifically, air is sucked into the air filter body 1 from top to bottom, and enters the filtering buffer chamber 4 formed by the oil cup 7 and the oil cup adapter 8 through the pipe orifice at the bottom of the gas collecting pipe 5 and the submergence oil blocking lip 6 of the oil cup adapter 8, because the submergence oil blocking lip 6 extends into the filtering buffer chamber 4, a semi-closed cavity is formed, and in the semi-closed cavity, due to the action of the suction force of an internal combustion engine, the air is repeatedly contacted with an oil film, dust in the air is adsorbed onto the oil film and is deposited to the bottom of the cup under the action of gravity, and oil bath filtering is completed. After the air is fully filtered by the oil bath, the air enters the internal combustion engine through the filter element 2, the filter element bracket 9 on the oil cup adapter 8 supports and compresses the filter element 2, the gap generated between the filter element 2 and the air filter body 1 due to looseness is avoided, and the filtering effect of the filter element is ensured.
The drawings and description above represent only preferred embodiments of the utility model and are not intended to limit the utility model, since numerous modifications and variations will readily occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
