Abstract
The utility model discloses an automobile air prefilter. The main body of the prefilter is a shell (1); the side wall of the shell (1) is provided with an air inlet window shutter (2); the lower part of the shell (1) is provided with an outer tube (3); a rotational flow fan (4) is arranged at the upper end of the outer tube (3); an inner tube (6) is arranged in the outer tube (3) below the rotational flow fan (4); a high-speed rotational fan (5) is arranged at the upper end of the inner tube (6); and a dust outlet (7) is formed at the lower end of the outer tube (3). The automobile air prefilter can play a role in removing dust from external air; the window shutter (2) in the automobile air prefilter can play a role in dewatering; the conventional air inlet tube is replaced, so that the cost is lowered; the dust removing efficiency is up 91 percent, and the dewatering efficiency is up to 98 percent; the automobile air prefilter is resistant to cold, high temperatures and strong shocks; and the service lives of an air filter and an engine can be prolonged.
Description
Technical field
The utility model relates to prefilter, particularly a kind of automobile air prefilter.
Background technique
Automotive engine air intake system mainly is made of air filter suction tude, air-strainer, engine net tracheae.Its major function is to provide clean, sufficient fresh air to motor.And traditional air filter air feeder structure is very simple, include only the body of suction port and air outlet, the suction port end of body contacts with the air in the external world, the air outlet end of body is connected with the air-strainer suction port, dedusting, filtration are mainly completed by air-strainer, often there is larger dust granule to enter air-strainer, increased the weight of the filtration load of air-strainer, affect the life-span of air-strainer and the frequency of renew cartridge more.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned deficiency, and provides a kind of air to external world to play the rough dusting effect, makes the cleaner automobile air prefilter of air ratio that enters air-strainer.
The technological scheme that the utility model adopts is: the main body of automobile air prefilter is housing, its housing sidewall is established air inlet louvers, establish outer tube in described lower housing portion, the eddy flow fan is established in this outer tube upper end, below described eddy flow fan and establish within the outer tube inner tube, establish the High Rotation Speed fan in described inner tube upper end, dust exhaust port is established in described outer tube lower end.
the utility model automobile air prefilter, in the automobile traveling process, at first air enters venetian blind, the moisture of venetian blind this moment 91% in can filtered air, air after filtration enters the eddy flow fan, eddy flow shape due to air high-speed motion and eddy flow fan, make air and impurity thereof produce centrifugal force, the larger dust granule of quality in air, moisture content is all due to effect and the air separation of centrifugal force, the air of dustless like this water enters the High Rotation Speed fan of below more again with air and dust separation, air through purifying enters inner tube, the outer tube bottom, enter at last air-strainer.And dust and moisture are got rid of wall within the outer tube under the effect of centrifugal force, flow at last the dust exhaust port outflow of lower end along outer tube wall.
The utility model is take venetian blind as just considering, eddy flow fan and high-speed rotational fan filter thereof are main worry, outer tube and dust exhaust port are dust export, this structure not only to external world air play dustproof function, venetian blind in the utility model can also play the effect that dewaters, replaced traditional suction tude, reduce costs, its dedusting can reach 91%, and dewatering reaches 98%, and is cold-resistant, high temperature resistant, anti-macroseism can extend working life of air-strainer and motor, provides good air cleaning unit for China's car gage reaches Europe III.
Description of drawings
Fig. 1 is the structural representation of the utility model automobile air prefilter.
Embodiment
As shown in Figure 1, the utility model automobile air prefilter comprises: housing 1, the venetian blind 2 that dewaters, the eddy flow fan 4 of dustproof function can in time be drained the out High Rotation Speed fan 5 of dust of eddy flow, flutters outer tube 3, the dust exhaust port 7 of catching dust.Housing 1 sidewall of the present utility model is installed air inlet louvers 2, at housing 1 lower inside socket outer tube 3, these outer tube 3 upper ends installation eddy flow fans 4, below eddy flow fan 4 and establish inner tube 6 in outer tube 3, outer tube 3 and inner tube 6 can form one, establish High Rotation Speed fan 5 in inner tube 6 upper ends, the high-speed bearing 8 of this High Rotation Speed fan 5 is connected with inner tube 6 by dunnage 9, and dust exhaust port 7 is established in outer tube 3 lower ends.
the utility model automobile air prefilter working principle is: air enters intake duct by venetian blind 2, special construction due to venetian blind 2, rainwater can not enter prefilter along intake duct, air is removed airborne part dust through the sector structure of venetian blind 2, first filtered air continues to arrive eddy flow fan 4, make the air of high speed operation produce high-speed rotational, effect due to centrifugal force, airborne dust is separated, the dust that is separated is blown into outer tube 3 by High Rotation Speed fan 5, in case sucked by secondary, dust in outer tube 3 is discharged prefilter through dust exhaust port 7 like this, thereby reach the effect of filtration.
Claims (1)
1. automobile air prefilter, it is characterized in that: the main body of this prefilter is housing (1), its housing (1) sidewall is established air inlet louvers (2), establish outer tube (3) in described housing (1) bottom, eddy flow fan (4) is established in this outer tube (3) upper end, fan (4) below and establish inner tube (6) in outer tube (3) at described eddy flow, establish High Rotation Speed fan (5) in described inner tube (6) upper end, dust exhaust port (7) is established in described outer tube (3) lower end.
