Abstract

The utility model discloses an automatic switching device for a general gasoline engine valve. The utility model is composed of an outer sleeve, a lower sleeve, a valve seat, an electric heating device, an expanding piston flex system and a connecting rod, wherein one end of the outer sleeve is sealed and the other end is movably connected with the lower sleeve. The other end of the lower sleeve is movably connected with the valve seat. The electric heating device is positioned at the sealed end in the outer sleeve, and a positive direct current electrode, a negative direct current electrode and an electric heating element are electrically connected to form the electric heating device. The expanding piston flex system is composed of an expanding piston, an insulating sleeve, a tappet and a returning spring. The expanding piston flex system contacts the electric heating device and is positioned in the lower sleeve. The connecting rod forms an f shape to be hinged with the valve seat. The upper end head of the connecting rod is positioned in a lower hole of the valve seat and contacts the lower end head of the tappet. The utility model only needs to be communicated with a 12V direct current circuit, and a valve of an engine can be automatically opened in 1-2 minutes. In about 50 minutes after the utility model is stopped, the valve can be automatically closed and the whole switching process is fully automatic.

Description

A kind of recloser of general gasoline engines air door

Technical field

The utility model relates to a kind of petrol engine air door switch device, particularly a kind of recloser of general gasoline engines air door.

Background technique

Known petrol engine air door switch is manual.Will close air door when petrol engine is opened, should open air door after the unlatching, operation is carried out in two steps, and arranged a bit of blanking time.Usually, people drive a car or during motorcycle, before this at petrol engine, promptly under the air door closed condition of motor car are started, and just air door are opened after a while, and be that vehicle is among the operation this moment.For automobile, the air door switch of motor is positioned at operator cabin, and the driver is handy, but just air door is opened after also often existing the driver to forget to open air door or spent the long period, like this, motor is not to work under suitable environment just, not only excessive fuel consumption, and output power is low.For motorcycle, because the damper positions of motor is below car, the switch air door is very inconvenient, even the somebody causes traffic accident in order to open air door in riding.

The model utility content

The purpose of this utility model is: at the deficiencies in the prior art, provide a kind of general gasoline engines air door switch device of recloser fully.

Realize that the technological scheme that above-mentioned purpose is taked is: a kind of recloser of general gasoline engines air door, by overcoat, trap, valve seat, Electric heating appliance, expansion piston telescopic system and connecting rod form; The one end sealing of described overcoat, the other end and a described end of trapping flexibly connect, and a wire guide is arranged on the sidewall of overcoat; A step through-hole is arranged on the described valve seat, and the macropore of the described the other end of trapping and described valve seat step through-hole flexibly connects, and a side of valve seat has the coupling shaft of a plural fixed installation hole and a connecting rod; " f " type that is shaped as of described connecting rod, there is a hole that is connected with described valve seat axle the position of departing from middle, close upper end on connecting rod, the upper tip of connecting rod is in the aperture of described valve seat step through-hole, and the lower end of tappet contacts in the aperture of valve seat step through-hole with the upper tip of connecting rod; Described Electric heating appliance is positioned at the closed end of described overcoat, and described expansion piston telescopic system contacts with described Electric heating appliance, is positioned at described trapping.

Above-mentioned Electric heating appliance is electrically connected by positive direct-current electrode negative and two interelectrode electric heating elements to be formed.

Above-mentioned expansion piston telescopic system is made up of an expansion piston, an insulating bush, a tappet and a return spring that connects as one with insulating bush, and return spring is arranged in described trapping, and is enclosed within on the described tappet.

The utility model only need be connected the 12V DC circuit, and the air door of 1-2 minute rear engine will be opened automatically; Circuit disconnects naturally during shutdown, and after about 50 minutes, air door will be closed automatically, and whole switching process is full-automatic.

Description of drawings

Fig. 1 is the sectional view of an embodiment's of the utility model overall structure along axis;

Fig. 2 is that the shape and the position of each parts among Fig. 1 concerns schematic representation.

Among the figure: 1. overcoat, 2.4. power line, 3 electric heating elements, 5. expansion piston, 6. insulating bush, 7. tappet, 8. return spring, 9. trap, 10. valve seat, 11. connecting rods, 12. wire guides, 13. air doors.

Embodiment

Below in conjunction with Figure of description the utility model is described in further detail:

As illustrated in fig. 1 and 2, a kind of recloser of general gasoline engines air door, by overcoat 1, trap 9, valve seat 10, Electric heating appliance, expansion piston telescopic system and connecting rod 11 form; One end of overcoat 1 seals, and the other end has internal thread, and spins with the outside thread on 9 tops of trapping, and a wire guide 12 is arranged on the sidewall of overcoat 1; A step through-hole is arranged on the

valve seat

10, and 9 the bottom of trapping is connected in the macropore of valve seat 10 step through-holes, and a side of valve seat 10 has the coupling shafts of two fixed installation holes and a connecting rod, and the fixed installation hole is used for recloser is installed in Carburetor; The shape of connecting rod 11 looks when it is erect and resembles " f " font, on connecting rod 11, depart from middle, near the position of upper end have one with 10 holes that are connected of valve seat, the upper tip of connecting rod 11 is in the aperture of valve seat 10 step through-holes, the termination of tappet 7 contacts in the aperture of valve seat 10 step through-holes with the upper tip of connecting rod 11, and the end of connecting rod 11 contacts with the cursor of air door 13.
