Abstract
The utility model relates to a forced exhaust fan in a motor vehicle. An air inlet pipe 5 and an air exhaust pipe 8 are respectively installed on a casing 7 of the outer part of an air suction fan 2, the air suction fan 2 is installed on a main shaft 4 of a motor 3, an electromagnetic valve 1 and a baffle plate 11 are installed at the outer end part of the air exhaust pipe, and a motor and the electromagnetic valve are respectively connected with a power supply 14 by a single-pole two-way switch 15. The utility model has the forced air-exchanging function. The power of the electromagnetic valve is switched on when the motor stops working, so the baffle plate can be absorbed outside a pipe mouth of the air exhaust pipe; thus, the sealing function is realized. The utility model has the advantages of low cost and less power utilization.
Description
The utility model belongs to the air interchanger in the self-propelled vehicle.
At present,, and cause in the car oxygen content low because vehicle sealing is tighter, the pernicious gas too high levels, it makes driver's brain response blunt, limbs fatigue, above reason becomes the hidden danger of various traffic accidents.And the various scavenger fans that use at present, the effect of its forced circulation is low, and does not have the function of exhaust as required and at any time.
The purpose of this utility model is a forced-ventilated scavenger fan in a kind of self-propelled vehicle of design, and it should have the boost ventilator function, can get rid of pernicious gas in the car by actv., sucks fresh air simultaneously, guarantees oxygen-supplying amount in the operator's compartment, reduces traffic accident and takes place; It in addition can be as required degassing function at any time, and should have the advantage that cost is low, electricity consumption is few, efficient is high.
The utility model comprises motor 3, suction fan 2, air inlet pipe 5, freeing pipe 8, suction fan 2 is installed on the main shaft 4 of motor 3, the outside of suction fan 2 is equipped with housing 7, air inlet pipe 5 is connected on the housing 7 in center shaft the place ahead of suction fan 2, the pore of air inlet pipe 5 communicates with the inside of housing 7, and freeing pipe 8 is connected a side of housing 7, and the pore of freeing pipe 8 communicates with the inside of housing 7, the outer end of freeing pipe 8 is connected on the car body shell, and its pore communicates with the external world.
The utility model motor 3 rotates, and drives suction fan 2 simultaneously and rotates, and produce stronger suction, by air inlet pipe 5 and freeing pipe 8 waste gas in the car is discharged rapidly.This mechanism has the boost ventilator function, can get rid of pernicious gas in the car by actv., sucks fresh air simultaneously, guarantee oxygen-supplying amount in the operator's compartment, reduce traffic accident and take place, it also has the function of exhaust as required and at any time, and has the advantage that cost is low, electricity consumption is few, efficient is high.
Fig. 1 is a front view of the present utility model, and Fig. 2 is the left view of Fig. 1, and Fig. 3 is a circuit diagram of the present utility model.
Embodiment: present embodiment is by motor 3, suction fan 2, electromagnetic valve 1, air inlet pipe 5, freeing pipe 8, housing 7, baffle plate 11, power supply 14, hilted broadsword bidirectional switch 15 is formed, suction fan 2 is installed on the main shaft 4 of motor 3, the outside of suction fan 2 is equipped with housing 7, air inlet pipe 5 is connected on the housing 7 in center shaft the place ahead of suction fan 2, the pore of air inlet pipe 5 communicates with the inside of housing 7, freeing pipe 8 is connected a side of housing 7, the pore of freeing pipe 8 communicates with the inside of housing 7, the outer end of freeing pipe 8 is connected on the car body shell, its pore communicates with the external world, electromagnetic valve 1 center is a metal tube 9, the outside is wound with coil 10, metal tube 9 is enclosed within the outer end of freeing pipe 8, baffle plate 11 is located on the freeing pipe 8 outer end mouths of pipe, baffle plate 11 1 sides are hinged on the boss 13 of freeing pipe 8 outer ends by axle 12, the positive pole of power supply 14 is connected with a point of hilted broadsword bidirectional switch 15 by lead, the b point of hilted broadsword bidirectional switch 15 is connected with an end of motor 3 by lead, the c point of hilted broadsword bidirectional switch 15 is connected with the d end of coil 10 by lead, and the e end of coil 10 is connected by the negative pole of lead with power supply 14 respectively with the other end of motor 3.
When hilted broadsword bidirectional switch 15 is connected to the b point, motor 3 rotates, drive suction fan 2 simultaneously and rotate, and produce stronger suction, waste gas in the car is discharged rapidly by air inlet pipe 5 and freeing pipe 8, when hilted broadsword bidirectional switch 15 is connected to the c point, motor 3 outages, electromagnetic valve 1 energising also produces magnetic force, and baffle plate 11 adopts iron material to make, so under the effect of electromagnetic valve 1 magnetic force, be adsorbed on outside freeing pipe 8 mouths of pipe, play sealing function.
