Summary of the invention
In order to address the above problem, the purpose of this utility model provides a kind of smog that can car is indoor and is extracted into the indoor fume extractor of the outdoor car of car rapidly.
The technical solution of the utility model is: the indoor fume extractor of this kind car is characterized in that: it comprises smoke exhaust pipe, air suctiton ventilator and drive motor, check valve and master cock; The end that described smoke exhaust pipe is arranged on car chamber top is flat sealing and the below is provided with a plurality of pores that communicate with operator's compartment, and the other end of smoke exhaust pipe connects air suctiton ventilator, air suctiton ventilator connection drive motor, and drive motor is fastened on the master cock at top, car chamber; The gas outlet of described air suctiton ventilator is established one and is prevented the check valve that gas flows backwards; Air suctiton ventilator and drive motor all are fixed on the car body.
Further program of the utility model is: master cock is a manual switch.Be arranged on any handled easily part in the operator's compartment.This switch of M/C can be controlled motor and rotate, and realizes exhausting or stops exhausting.
Further program of the utility model can also be: described master cock also is provided with an automatic switch; Described automatic switch is connected with the sense cigarette device probe that is fixed on the indoor Top of car.Automatic switch can be set up separately, is rotated by sense cigarette device probe control motor, realizes exhausting or stops exhausting.Automatic switch can also be combined as a whole with hand switch and set up, and a stop bit is set in addition again, constitutes three double-throw switchs of hilted broadsword.During conversion, can control motor and rotate between M/C position and stop position when switch, realize exhausting or stop exhausting; When switch automatically between operating position and the stop position during conversion, rotate by sense cigarette device probe control motor, realize exhausting or stop exhausting.
Further program of the utility model can also be: the smoke exhaust pipe that can consider to install one or more smoke exhaust pipes, air suctiton ventilator and drive motor, check valve composition to different vehicles, shape according to car, be distributed in the place ahead or the rear of operator's compartment, perhaps rear, the place ahead all is provided with.Sense cigarette device probe can be set to all motors of control, also can be a plurality of and each sense cigarette device probe all can control all motors simultaneously.
Master cock connects power supply in the car; Air suctiton ventilator and drive motor be arranged in the baggage container or engine case in.Described smoke exhaust pipe is close to the car body top installation, and install along car body inner top panel position at its middle part; The gas outlet of described air suctiton ventilator is established one and is prevented the check valve that gas flows backwards, and in the time of can preventing that air suctiton ventilator from quitting work, the air refluence carriage return that has gasoline or machine oil flavor in the engine case or in the baggage container is indoor.By sense cigarette device pop one's head in indoor air quality situation of automatic inspection vehicle and the work of controlling and driving driven by motor air suctiton ventilator.Sense cigarette device probe is fixed on the indoor top of car, and master cock can be installed in the indoor top of car, also can be installed near the parking brake.
The beneficial effects of the utility model are: under the prerequisite that does not change automobile appearance and aerodynamic drag factor, guaranteed that the indoor air of car is fresh, not only made smog no longer endanger occupant's health, and make the occupant happy.This apparatus structure is simple, uses and installs very conveniently, is suitable for promoting.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation that the utility model implements to install four smoke exhaust pipes.
Among the figure: 1 drive motor, 2 air suctiton ventilators, 31 left front smoke exhaust pipes, 32 left back smoke exhaust pipes, 33 right front smoke exhaust pipes, 34 right back smoke exhaust pipes, 4 check valves, 51 left side sense cigarette device probes, 52 right sense cigarette device probes, three double-throw switchs of 6 hilted broadswords, 7 smoke exhaust pipe plat parts.
The specific embodiment
As shown in drawings, among this embodiment: the indoor fume extractor of car mainly comprises left front smoke exhaust pipe 31, left back smoke exhaust pipe 32, right front smoke exhaust pipe 33,34 4 smoke exhaust pipes of right back smoke exhaust pipe and corresponding air suctiton ventilator 2, drive motor 1.Smoke exhaust pipe one end is flats and port closed, the below of smoke exhaust pipe plat part 7 is provided with a plurality of pores that communicate with operator's compartment, the other end of smoke exhaust pipe connects air suctiton ventilator 2, the gas outlet of air suctiton ventilator 2 is established one and is prevented the check valve 4 that gas flows backwards, the effect of Non-return air valve 4 is when air suctiton ventilator 2 quits work, prevent in the engine case or baggage container in to have the air refluence carriage return of gasoline or machine oil flavor indoor.Air suctiton ventilator 2 connects drive motor 1, and drive motor 1 connects three double-throw switchs 6 of a hilted broadsword, and three double-throw switchs of hilted broadsword 6 connect left side sense cigarette device probe 51 and right sense cigarette device probe 52, and two sense cigarette device probes can both be controlled 1 work of four drive motor.
Smoke exhaust pipe is close to car body top and is installed, and install along car body inner top panel position at its middle part, wherein left front smoke exhaust pipe 31 and right front smoke exhaust pipe 33 bonded assembly air suctiton ventilators 2 and drive motor 1 all are arranged in the engine case, and left back smoke exhaust pipe 32 and right back smoke exhaust pipe 34 bonded assembly air suctiton ventilators 2 and drive motor 1 all are arranged in the baggage container; Three double-throw switchs 6 of hilted broadsword and left side sense cigarette device probe 51, right sense cigarette device probe 52 all are fixed on the indoor top of car.
When driver or passenger are stop bit when pulling manual position from middle position with three double-throw switchs of hilted broadsword, the rotation of switch on together of four drive motor 1 and air suctiton ventilator 2, air suctiton ventilator 2 middle parts generation negative pressure.Because this one links to each other with smoke exhaust pipe, make and produce negative-pressure sucking in the smoke exhaust pipe, with the aperture suction smoke exhaust pipe of the indoor because smog that smoking causes of car, again through air suctiton ventilator suction engine case and baggage container along smoke exhaust pipe plat part 7 bottoms.It is indoor that fresh air then enters car by the ventilation inlet of original air-conditioning.Like this, just can under the situation that vehicle stops or very low, the calm weather of the speed of a motor vehicle, vehicle window car door close, keep the indoor air of car fresh, thereby guarantee that the occupant's is healthy.
When driver or passenger pull opposite side automatically during the position with three double-throw switchs 6 of hilted broadsword, four drive motor 1 will be controlled by left and right sense cigarette device probe respectively, when as long as left and right sense cigarette device probe has one of them perception to have smog to exist, to connect four drive motor 1 automatically rotates together, up to about sense cigarette device probe 51,52 all barely feel smog and exist, drive motor 1 stops operating.
When three double-throw switchs 6 of hilted broadsword being pulled interposition when being stop bit, the native system outage quits work.
