(1) due in use, air filter is connected with motor, and silencing apparatus is connected with outlet pipe, and the layout of its pipeline makes the distance between air filter and silencing apparatus longer, and trouble is installed, and cost is high;
(2) adopt one-way valve, can produce the air-flow suck-back when equipment downtime, exhaust shakiness or vehicle have operating mode to occur;
(3) when failure of check valve, need to change one-way valve, and the damage of one-way valve can destroy air filter, the increase cost;
(4) air filter is without rain-proof waterproof device, and filter efficiency is low.
The model utility content
The shortcomings such as the applicant is high for cost in above-mentioned existing production technology, and filter efficiency is low provide a kind of blower fan lead-jetting device of automotive engine air intake system, thereby have greatly improved filter efficiency, and the air-strainer long service life reduces costs.
The technological scheme that the utility model adopts is as follows:
A kind of blower fan lead-jetting device of automotive engine air intake system, comprise air-strainer, the input end of described air-strainer is equipped with prefilter by the transition pipeline, connect a bend pipe on described prefilter, the mouth of pipe of described bend pipe connects trunnion, one end of described trunnion connects dc fan, and the other end of described trunnion is exhaust port.
Its further technological scheme is:
The outside loop configuration place of described prefilter and transition pipeline joint is the suction port of prefilter;
Described dc fan is connected with vehicle power;
Described air-strainer is fixedly installed on bearing;
Described trunnion adopts Venturi tube;
Described trunnion two ends diameter is greater than the diameter at middle part.
The beneficial effects of the utility model are as follows:
The utility model is rational in infrastructure, installs with easy to make, by a prefilter is installed on air-strainer, prefilter connects dc fan by pipeline, adopts independently that blower fan is main power source, need not to be equipped with one-way valve, cost is low, and filter efficiency is high, good reliability.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As Fig. 2, Fig. 3 and shown in Figure 4, the blower fan lead-jetting device of the automotive engine air intake system of the present embodiment comprises air-strainer 7, and air-strainer 7 is fixedly installed on bearing 9; The input end of air-strainer 7 is equipped with prefilter 5 by transition pipeline 6, connect a bend pipe 4 on prefilter 5, the mouth of pipe 3 of bend pipe 4 connects trunnion 2, and an end of trunnion 2 connects dc fan 1, dc fan 1 is connected with vehicle power, and the other end of trunnion 2 is exhaust port 8.
The outside loop configuration place of prefilter 5 and transition pipeline 6 joints is the suction port of prefilter 5.Suction port arranges the below with prefilter 5, has rainproof water-proof function, improves filter efficiency.
Trunnion 2 adopts Venturi tube, and trunnion 2 two ends diameters are greater than the diameter at middle part.Because the diameter of the trunnion 2 of the mouth of pipe 3 joints is less, when dc fan 1 is blown into air-flow in the trunnion 2, in the interior generation negative pressure of the less trunnion 2 of diameter, can smoothly the dust in pipeline be drawn good filtration effect.
The utility model adopts dc fan 1, and 1 of dc fan needs to connect vehicle power, need not other connecting circuit, adopts independently ECU (Electrical Control Unit), can control main jet pipe flow by the signal that reads Engine ECU.
Owing to adopting dc fan 1, dc fan 1 can not produce counter-rotating, has avoided producing the air-flow suck-back in prior art because shut down, and need not to configure the necessary one-way valve of waste gas ejecting technology in prior art, reduces costs.
In actual using process: start dc fan 1, dc fan 1 is blown into air-flow in trunnion 2, and gas enters from the inlet of prefilter 5, and by the effect of prefilter 5, the gas after filtration leads to trunnion 2 by bend pipe 4, discharges from the exhaust port 8 of trunnion 2; Be gas after pre-filtering and enter gases in air-strainer 7, native system has improved the filter efficiency of prefilter 5, makes the filter efficiency of prefilter 5 reach more than 96%, has extended the working life of air-strainer 7 filter cores, reduces costs.
Above description is to explanation of the present utility model, is not the restriction to model utility, and the utility model limited range within protection domain of the present utility model, can be done any type of modification referring to claim.
