Description
Technical field
The utility model belongs to sky filter technical field, specifically, relates to the empty filter on a kind of general gasoline engines.
Background technique
During reciprocating machine (internal-combustion engine, reciprocating compressor etc.) work, just will aggravate the wearing and tearing of part,, that is to say the sky filter so air-strainer must be housed if suck impurity such as containing dust in the air.Air-strainer is made up of filter core and housing two-part.The major requirement of air-strainer be filtering efficiency height, flow resistance low, can the long period use and service free continuously.Air filtering has 1. inertia-type of inertia-type, filtering type and 3 kinds of modes of oil bath type: because the density of impurity is big than the density of air, when impurity rotated with air or takes a sudden turn, the interaction energy of centrifugal inertia force was separated impurity from air-flow.2. filtering type: the guiding air flows through metal screen or filter paper etc., impurity is stopped and sticks on the filter core.3. oil bath type: be provided with oil pan at air filter bottom section, utilize the air-flow racing to impact machine oil, impurity is separated and viscous in machine oil, and the machine oil droplet that has been agitated is with the airflow passes filter core, and sticks on the filter core.Can further adsorb impurity when air flows through filter core, thereby reach the purpose of filtering.
The filtering effect of existing empty filter is all undesirable, time one is long, having many particulates adheres on filter core morning, thereby cause the forfeiture of sky filter effect, therefore the frequent filter core of changing in the empty filter of needs could satisfy the requirement to gas, so both shorten the working life of empty filter, increased cost simultaneously again.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of good filtration effect, can effectively reduce the empty filter of general gasoline engines that micronic dust enters.
The technical solution of the utility model is as follows: the empty filter of the general gasoline engines of design, its main points are: comprise the water conservancy diversion top cover, body, lubricating cup and filtration assembly, wherein said body is by the air inlet cavity that is arranged on the middle part, the air outlet formation that is coated at the filtration cavity of described air inlet cavity and is arranged on described filtration cavity top and communicates with this filtration cavity, connect described water conservancy diversion top cover in described body upper end, the suction port that is provided with on this water conservancy diversion top cover communicates with described air inlet cavity, be connected with described lubricating cup in described body lower end, described air inlet cavity, lubricating cup and filtration cavity communicate, described filtration assembly is installed, and this filtration assembly is enclosed within outward on the described air inlet cavity in described filtration cavity.
There are not enough creatively designs such as poor filtration effect in the utility model at existing empty filter, adopt above structure, air enters the suction port that this water conservancy diversion top cover is arranged circumferentially from water conservancy diversion top cover below, thereby make air behind the water conservancy diversion top cover, enter the air inlet cavity of body, when air flows out the air-inlet cavity body under action of inertia, make airborne a large amount of dust stay in the machine oil of air inlet cavity below lubricating cup, so make the grey ability of storage of the present utility model stronger, longer service life, at last, air flows out from the air outlet of body after assembly filters through filtering again, finally obtains clean air flow Carburetor.
Described filtration assembly by last web plate, carefully filter sponge, coarse filtration sponge and down web plate constitute, wherein the coarse filtration sponge is set in described web plate down upper end, in this coarse filtration sponge upper end thin filtration sponge is set, in this thin sponge upper end of filtering web plate is set, described upward web plate upper end is against the epicoele wall of described filtration cavity, and described web plate down is positioned at described lubricating cup top.Adopt above structure, when air enters the filtration assembly, it is successively by following web plate, coarse filtration sponge, carefully filter sponge and last web plate, thereby make airborne impurity etc. according to its big or small degree successively by web plate, coarse filtration sponge down with carefully filter sponge and filter, thereby obtain closing the gas that symbol requires.
Between described web plate down and described lubricating cup, be provided with resistance and spatter oily dividing plate, described resistance is spattered the projection that is arranged circumferentially on the oily dividing plate and is against described web plate lower end surface down, this resistance is spattered oily dividing plate lower end and is against in the hoop support of described lubricating cup inner chamber, spatter in described resistance and to have louvre type wind hole on the oily dividing plate, adopt above structure, spatter in resistance under the stopping of oily dividing plate, prevent that the machine oil in the lubricating cup from spattering on described web plate down and coarse filtration sponge, thereby the filtering effect of web plate and coarse filtration sponge is well guaranteed, simultaneously, described resistance is spattered and is had louvre type wind hole on the oily dividing plate, not only have the machine oil of stopping thus and splash on the coarse filtration sponge, have the effect of certain prevention dust again.
To be connected more reliably in order making between water conservancy diversion top cover and the body, to be convenient to dismounting simultaneously again, described water conservancy diversion top cover is threaded with the air inlet cavity of described body.
Between described body and described lubricating cup seal ring is installed, this structure can prevent the lubricating oil leakage in the lubricating cup.
Beneficial effect: the utlity model has following characteristics: 1, changed air flow channel, made more dust stay in the machine oil, made the storage ash ability of sky filter stronger, longer service life, better protection motor; 2, water conservancy diversion top cover, body and lubricating cup all adopt screw connection structure, make easier dismounting in the using process; 3, the moulding of oily dividing plate employing plastic shutter formula is spattered in resistance, so not only has to stop that machine oil splashes the effect of filtering sponge, have the effect of certain prevention dust again, and technology is simpler.Have easy to process, easy to use, be easy to characteristics such as realization.
