Abstract

The utility model discloses an air cleaner without a filter element. The utility model is mainly composed of a box body which is provided with an air inlet pipe and a box cover which is provided with an air outlet pipe, wherein, the inner wall of the box cover and the inner part of the box body are respectively provided with a group of annular baffles, the two groups of annular baffles are arranged in the alternating way to form a turning air duct, the inner of the box body is provided with oil liquid, the air enters the oil liquid to have oil bath and wash along the turning air duct for a plurality of times, and the goal of cleaning air is realized. The utility model has the advantages of simple structure, easy fabrication, and convenient cleaning and maintenance; the utility model can supply sufficient cleansing dustless combustion air to the engine.

Description

Centreless formula air-strainer

The utility model relates to a kind of air-strainer that is installed on the internal-combustion engine, belongs to the air inlet device of motor, specifically a kind of centreless formula air-strainer that is specially adapted to motor car engine.

We know: explosive motor needs to consume a large amount of air in the course of the work, but, in air, contain more dust dust, if the dust dust that exists in the air enters the cylinder of motor, can stick on the lubricant film of cylinder surface, can accelerate cylinder, piston and wear of piston-rings speed sharp.For guaranteeing the motor proper functioning, prolong the operating life of motor, must carry out cleaning to air, promptly must remove airborne small dust dust granules, supply with qualified clean air to motor.What generally adopt on explosive motor at present is the filtering type air-strainer, it mainly is made of housing, filter core, lid etc., the guiding air passes through filter core, make dust contained in the air, dust granules be filtered isolation and stick to cartridge surface, reach purpose to the motor supplying clean air.But owing to adopt filter cartridge construction, in use cleaning the maintenance dismounting comparatively bothers, do not note also damaging easily filter core slightly, influence the filtering effect of air, and filter core also often need be changed, and increases operating cost, because dust dust sticks to cartridge surface, increase the filtration resistance of air, the not enough phenomenon that influences its proper functioning of air feed occurs.Chinese patent CN2288282Y discloses the utility model patent that a kind of name is called " the efficient filter cleaner of internal-combustion engine ", it mainly is made up of getter pipe, air supply pipe and filtering tank, filtered fluid is housed in the filtering tank, air supply pipe is connected on the suction tude of cylinder, the getter pipe is connected on the outlet pipe of cylinder, and when cylinder operation, the waste gas that cylinder is discharged resupplies cylinder combustion usefulness after being absorbed into the filtering tank inner filtration, the characteristics of this filter cleaner are to reduce the exhaust gas discharging amount, reduce environmental pollution.

The purpose of this utility model be propose on the basis of existing technology a kind of simple in structure, fabricating cost is low, cleans centreless formula air-strainer easy to maintenance.

The purpose of this utility model is achieved by the following technical solution:

A kind of centreless formula air-strainer, it is made of box body that suction tude is installed and the lid that steam outlet pipe is installed, and one group of toroidal membrane is installed in box body, and the lid inwall is equipped with one group of toroidal membrane, two groups of toroidal membranes are alternately arranged the air passageways that forms turnover, contain fluid in the box body.On steam outlet pipe, be set with flexible pipe, be connected with Carburetor or directly be connected with the suction tude of motor by flexible pipe.Air enters through the suction tude of centreless formula air-strainer, the air passageways guiding repeated multiple times of the turnover that is formed by two groups of toroidal membranes alternately arranging enters fluid in the box body and carries out oil bath and wash, can remove and contain small dust dust granules in the air, realize supplying with the purpose of qualified clean air to motor.

The utility model is in box body and the lid inwall is separately installed with one group of toroidal membrane, two groups of toroidal membranes are alternately arranged the air passageways that forms turnover, contain fluid in the box body, air repeatedly enters fluid along the air passageways of transferring and carries out the oil bath washing, the purpose of qualified and sufficient clean air is supplied with in realization to motor, the utlity model has simple in structurely, clean advantage easy to maintenance.

Accompanying drawing is a structural representation of the present utility model.

The utility model will be further described below in conjunction with accompanying drawing:

A kind of centreless formula air-strainer, it is made of box body 1 that suction tude 2 is installed and the lid 4 that steam outlet pipe 5 is installed, one group of toroidal membrane 7 is installed in box body 1, the inwall of lid 4 is equipped with one group of toroidal membrane 3, two groups of

toroidal membranes

3,7 alternately arrange the air passageways 9 that forms turnover, contain fluid 8 in the box body 1, the flexible pipe 6 that is set on the steam outlet pipe 5 is connected with Carburetor or directly is connected with the suction tude of motor, air enters two groups of toroidal membranes 3 arranging by alternately through suction tude 2, air passageways 9 guiding of 7 turnovers that form, the fluid 8 that repeated multiple times enters in the box body 1 carries out the oil bath washing, can remove the minute dust dust granules that contains in the air, supply with qualified burning clean air to motor.The utility model can be according to the structural feature of various motor car engine, box body 1 can be made round-shaped or square configuration or other shape, also can be according to the size design toroidal membrane 3 of the required air demand of motor, 7 height dimension and position dimension, thereby regulate the Throughput of air passageways 9, satisfy the needs of motor proper functioning, the utlity model has simple in structure, make easily, clean characteristics easy to maintenance, can supply with the sufficient dustless combustion air of cleaning to motor, can make engine combustion abundant, reduce blowdown flow rate, alleviate environmental pollution, can prolong the operating life of motor effectively.
