Abstract

A gasoline engine oil bath-type air filter includes a shell which is provided with an air inlet tube and a petrol engine combustion chamber interface, and a sponge filter cartridge is provided in the shell; the filter is characterized in that the sponge filter cartridge is at the lower part of shell cavity, the throat opening of shell cavity crosses the sponge filter cartridge and is connected with an oil cup of the lower part of shell; moreover, the air inlet of the air inlet pipe is provided with a filter screen.

Description

The empty filter of petrol engine oil bath formula

Technical field the utility model belongs to the empty filter technical field of petrol engine, is specifically related to the empty filter of a kind of petrol engine oil bath formula.

The empty filter of the petrol engine of background technique prior art comprises housing, and housing is provided with suction tude, combustion chamber of petrol engine interface, is provided with a sponge filter core in the housing chamber.The empty filter air of this structure is entered in the housing by suction tude, through the sponge filter element filtering, is gone out by the combustion chamber of petrol engine interface and to enter combustion chamber of petrol engine.The empty filter of the petrol engine of prior art very easily stop up and filtering effect relatively poor, safeguard that clearing times is more, cause piston ring, the cylinder body wearing and tearing of petrol engine easily, cause the power of petrol engine to reduce, start fault such as difficulty, the life-span of petrol engine is reduced.

The summary of the invention the purpose of this utility model is the technical problem for the empty filter poor filtration effect of solution prior art, thereby provides a kind of petrol engine oil bath formula empty filter, to overcome the deficiencies in the prior art.

To achieve these goals, the empty filter of the utility model petrol engine oil bath formula, comprise housing, housing is provided with suction tude, combustion chamber of petrol engine interface, be provided with the sponge filter core in the housing chamber, its main points are bottoms that the sponge filter core is positioned at the housing inner chamber, and the aditus laryngis of housing inner chamber passes the sponge filter core and is communicated with the lubricating cup that is arranged on the housing lower end; The suction port of said suction tude is provided with filter screen.

In order to improve the filtering effect, said sponge filter core is double-deck filter core, and one deck is a gross porosity sponge filter core, and another layer is a pore sponge filter core.

Working principle of the present utility model is: air carries out the first time at the suction port of empty filter by filter screen and filters, and foreign material that can be tentatively that some are bigger, branches and leaves etc. are blocked in outside the sky filter, enters the sky filter then through the gas of the first road filter screen; Because the aditus laryngis of empty filter more carefully and longer, at this moment quicken through the gas flow at this place, because the weight of the dust granule self in the gas and inertia enter and carry out second time in the machine oil in the lubricating cup that is arranged on sky filter bottom and filter, because the viscosity of machine oil itself is with some dust granule oil baths adhesions; The small light granules that some is not adhered to by machine oil, by the absorption of sponge filter core, the air that enters petrol engine like this passes through cleaner that this three-stage filtration can become, and can satisfy the usage requirement of petrol engine.

The utility model beneficial effect compared with prior art is owing to the air that enters combustion chamber of petrol engine has carried out triple filter, improved the filtering effect of empty filter, and maintaining to be convenient.When improving filtering effect, as long as the lubricating cup of bottom is backed out, more change engine oil and filter core get final product during maintaining.

Appended drawings is the utility model structure and working principle schematic representation.

1. lubricating cups, 2. lubricating cup pads, 3. filter core supports, 4. gross porosity sponge filter cores, 5. pore sponge filter cores, 6. filter core support pads, 7. filter core pressing plates, 8. housings, 9. suction tude, 10. filter screens, 11. combustion chamber of petrol engine interfaces among the figure; The direction of arrow indication among the figure is air direct.

Embodiment with reference to the accompanying drawings, it comprises housing 8 the utility model, housing 8 is provided with suction tude 9, combustion chamber of petrol engine interface 11, is provided with double-deck sponge filter core in the housing chamber, one deck is a gross porosity sponge filter core 4, another the layer be pore sponge filter core 5; The sponge filter core is positioned at the bottom of housing inner chamber, and the aditus laryngis of housing inner chamber passes the sponge filter core and is communicated with the lubricating cup 1 that is arranged on the housing lower end; The suction port of suction tude 9 is provided with filter screen 10.Adopt between lubricating cup 1 and the housing 8 among the figure and be threaded; Middle for improving sealing and anti-loosing effect employing lubricating cup pad 2; Filter screen 10 and suction tude 9, suction tude 9 and housing 8, housing 8 and filter core pressing plate 7 adopt interference fit between housing 8 and the filter core support 3.

Claims

1, the empty filter of a kind of petrol engine oil bath formula, comprise housing, housing is provided with suction tude, combustion chamber of petrol engine interface, be provided with the sponge filter core in the housing chamber, it is characterized in that said sponge filter core is positioned at the bottom of housing inner chamber, the aditus laryngis of housing inner chamber passes the sponge filter core and is communicated with the lubricating cup that is arranged on the housing lower end; The suction port of said suction tude is provided with filter screen.

2, the empty filter of petrol engine oil bath formula according to claim 1, the said sponge filter core of its feature is double-deck filter core, and one deck is a gross porosity sponge filter core, and another layer is a pore sponge filter core.
