Description
Technical field
The present invention relates to a kind of engine air inlet tube, particularly relate to a kind of air-cleaner snorkel.
Background technique
Engine aspirating system has bigger influence to the performance of motor, particularly has the vehicle of higher motility, the road conditions that run into; Environment will be more abominable, and making a difficult journey is common occurrence, when gas handling system does not have the water separation design; In rainy day or when paddling; Easily water is sucked motor, will cause engine misses when seriously intaking, influence the working life of motor; Slight water inlet also will make the resistance of gas handling system raise, and filtering efficiency reduces, and influences the power character and the Economy of car load.
Publication number is that the one Chinese patent application of CN101598088A discloses a kind of suction tude, and it has water-proof function and does not increase part number.The suction tude that is used for making air enter into internal-combustion engine from the outside has the tube wall of the resin of tubular form.Said tube wall comprises the Waterproof Breathable parts, and these parts have the Waterproof Breathable layer of scolding water layer and pore film to process that high-density fiber is processed, this two-layer being laminated to each other.This air inlet prevents water is sucked motor through a hygroscopic part, can prevent the water inflow of the engine problem to a certain extent, but this technological scheme need increase a Waterproof Breathable layer, has increased the air feeder structure complexity, has increased manufacture cost simultaneously.
Notification number is that the Chinese utility model patent of CN200985849Y discloses a kind of rotary flow type suction tude; The ingress of its inlet scoop is provided with venetian blind; The bottom of inlet scoop connects suction tude, is provided with the some spinning disks of arranging at an angle in the suction tude, and the below of spinning disk is provided with the branch dirt storehouse with inside and outside sleeve pipe; Divide bottom, dirt storehouse to be provided with dust exhaust port, interior pipe connects wind scoop.Air blocks a part of dust and moisture by venetian blind earlier; Then under the effect of spinning disk; Dust, moisture are discharged from minute dust exhaust port of bottom, dirt storehouse, and the dustless gas at eddy flow center is discharged from going out wind scoop, get into the normal air filter cleaner or directly get into motor.This technological scheme is got rid of dust, moisture through the mechanical eddy flow mechanism of an extra increase, and mechanism is comparatively complicated, and its operational safety receives certain influence.
Apply for before the applicant that notification number is that the Chinese utility model patent of CN201250732Y discloses the empty filter suction tude of a kind of water separation.It comprises suction port, air outlet, and suction port and air outlet are separately positioned on two faces of suction tude body, suction port and air outlet right face be the retaining wall face of an inclination, below, said air outlet is provided with the flowing water mouth.This technological scheme is simple in structure, and the effective moisture of separating most, but its result still can not satisfy the requirement of the vehicle with higher motility.
Summary of the invention
The present invention prevents that in order to solve the available engine suction tude moisture from sucking existing defective, and the water-proof performance through design adjustment on a kind of structure improves the engine air filter suction tude satisfies the harsh requirement of sports type vehicle.
Above-mentioned technical problem of the present invention mainly is able to solve through following technical proposals: a kind of water separation air-cleaner snorkel comprises suction tude oral area and suction tude main body portion; Said suction tude oral area is arranged on the head of said suction tude main body portion, is provided with a suction port and an air outlet; Said suction port and air outlet branch are located on two planes, between be provided with arc retaining wall, upper side wall and lower wall, be provided with water outlet at said arc retaining wall and connecting part, said air outlet; Said suction tude main body portion is an arc-shaped bend pipe, is provided with inside raised section in tube wall one side, and extend along said suction tude main body portion said raised section, and is provided with the resonant cavity connection mouth at destination county.At the suction tude oral area, air contained water is inhaled into the suction tude oral area under the effect of air-entry suction; Droplet in the air contained water is run on the retaining wall and above being trapped in, when rolling up large water drop, is discharged gas handling system through water outlet; After remaining gas-vapor mix gas gets into the suction tude body; Advance with the whirlpool shape, through said raised section the time, the gas-vapor mix gas that the whirlpool shape advances receives the obstruction of said raised section; Make remaining moisture being separated further, and once more moisture is separated through said resonant cavity connection mouth.
As a kind of optimal technical scheme of the present invention, the cross section of said raised section is " A " font, highly is 1/4th of place, said raised section suction tude caliber.Through cae analysis,, make between the increase of water separation effect and suction tude intake resistance to reach a desirable state of equilibrium when said raised section height is four/for the moment of place suction tude caliber.
As a kind of optimal technical scheme of the present invention, also be provided with a short retaining wall at said arc retaining wall and connecting part, said air outlet, and form a refluxing chamber with said arc retaining wall, said water outlet is arranged on the bottom of said refluxing chamber.Through the setting of short retaining wall, make the large water drop that accumulates through retaining wall along the diffluence of suction direction, under the effect of short retaining wall, produce eddy flow, discharge gas handling system through water outlet again.
As a kind of optimal technical scheme of the present invention, said short retaining wall is crescent shape, and is protruding to said upper side wall direction by said lower wall.
Through technological scheme of the present invention, air contained water separates through the effect formation one-level of retaining wall and short retaining wall at air inlet mouth of pipe place, discharges gas handling system through water outlet.
After remaining gas-vapor mix gas got into the suction tude body, the obstruction of said raised section formed secondary and separates, and made remaining moisture being separated further, and once more moisture was separated through said resonant cavity connection mouth.Through cae analysis, air contained water was advancing twice separation, can the moisture more than 90% be separated, and had satisfied the technical requirements to gas handling system of the vehicle of motility preferably.
