Description
Technical field
The utility model is related to a kind of miniature gasoline engines, especially a kind of carburetor for miniature gasoline engine.
Background technology
A kind of existing miniature gasoline engine contains carburetor, and carburetor is mainly by mixing chamber and float chamber two large divisions's group
At.Mixing chamber is mainly made of trunnion, main jet pipe, choke, air throttle etc., choke and air throttle be located at trunnion before,
The inside at both ends afterwards.The effect of choke is air capacity of the control into trunnion, is often used in gasoline engine starting.Air throttle is used
The gaseous mixture quantity into cylinder is controlled, gasoline engine horsepower changes with the variation of throttle opening size, air throttle is logical
Speed adjusting gear is crossed to control.When gasoline engine starting, need, by manually closing choke, again to beat choke after startup
It opens, therefore troublesome in poeration.
Utility model content
Technical problem to be solved in the utility model provides a kind of carburetor, which is convenient for the operation of gasoline engine.
In order to solve the above technical problems, a kind of carburetor of the utility model, containing mixing chamber and float chamber, mixing chamber contains
Trunnion, choke, air throttle, choke are arranged by choke rotary shaft in the interior front of trunnion, and air throttle passes through air throttle
Rotary shaft is arranged at the interior rear portion of trunnion, also contains diaphragm pump, and the outer end of the choke rotary shaft is equipped with link, on link
Equipped with torsional spring, diaphragm pump includes the pump housing, diaphragm, diaphragm rod, and the pump housing is equipped with venthole, and diaphragm is arranged in the pump housing, diaphragm rod
One end be arranged on diaphragm, the other end of diaphragm rod constituted with the link that choke rotary shaft outer end is equipped with it is hinged, it is described
The inner wall at the interior rear portion of trunnion is equipped with rear venthole, which is connected by pipeline with the venthole of diaphragm pump, the pump housing
It is arranged on the trunnion.
The pipeline that rear venthole in the trunnion on the inner wall at rear portion is connected with the venthole of diaphragm pump is equipped with unidirectional
Valve.
The pipeline that rear venthole in the trunnion on the inner wall at rear portion is connected with the venthole of diaphragm pump is heat-resisting
Hose.
The model FCV014AVDC of the check valve.
In above-mentioned carburetor, due to being equipped with torsional spring on the link of choke rotary shaft, under shutdown status,
Choke is to close；Upon start up, since the interior rear portion of trunnion is negative pressure state, at this moment the diaphragm rod of diaphragm pump can pull resistance
The link that air door rotary shaft outer end is equipped with rotates around rotary shaft and opens choke, therefore compared with prior art, no longer needs
Manually choke to be closed, to greatly facilitate operation.
Description of the drawings
Fig. 1 is the carburetor structure schematic diagram of the utility model；
Fig. 2 is A in Fig. 1 to structural schematic diagram.
Specific implementation mode
The technical solution of the utility model is described in further detail below in conjunction with the accompanying drawings：
Shown in Fig. 1 and Fig. 2, the utility model discloses a kind of carburetors, and containing mixing chamber and float chamber 1, mixing chamber contains
There are trunnion 2, choke 10, air throttle 13, choke 10 to be arranged in the interior front of trunnion 2, solar term by choke rotary shaft 11
Door 13 is arranged by air throttle rotary shaft 14 at the interior rear portion of trunnion 2.Above-mentioned carburetor also contains diaphragm pump 5, the choke rotation
The outer end of shaft 11 is equipped with link 3, and link 3 is equipped with torsional spring 7, which can make choke 10 tend to close.Not work
When making, the torsion of torsional spring 7 makes choke 10 close.Diaphragm pump 5 includes the pump housing 6, diaphragm, diaphragm rod 4, and the pump housing is equipped with ventilation
Hole.Diaphragm is arranged in the pump housing 6, and one end of diaphragm rod 4 is arranged on diaphragm, the other end and the choke rotary shaft of diaphragm rod 4
The link 3 that 11 outer ends are equipped with constitutes hinged.The inner wall at the interior rear portion of the trunnion 2 is equipped with rear venthole 12, the rear ventilation
Hole 12 is connected by pipeline 8 with the venthole of diaphragm pump 5, and the pump housing 6 is arranged on the trunnion 2.
In order to improve the stability after choke 10 is opened, and prevent oil gas from flowing back, the inner wall at rear portion in the trunnion 2
On the pipeline 8 that is connected with the venthole of diaphragm pump 5 of rear venthole 12 be equipped with check valve 9.
To reduce cost, the venthole phase of rear venthole 12 and diaphragm pump 5 in the trunnion 2 on the inner wall at rear portion
Pipeline 8 even is heat-resistant hose.
In order to reduce cost, the model FCV014AVDC of the check valve 9.
In above-mentioned carburetor, due to being equipped with torsional spring 7 on the link 3 of choke rotary shaft 11, shape is being shut down
Under state, the choke 10 under the action of 7 torsion of torsional spring of choke rotary shaft 11 is closed.Upon start up, due to trunnion
2 interior rear portion is negative pressure state, and at this moment the diaphragm rod 4 of diaphragm pump 5 can pull the link 3 that 11 outer end of choke rotary shaft is equipped with
It is rotated around rotary shaft and opens choke 10, therefore compared with prior art, it is no longer necessary to manually choke 10 is closed, to
Greatly facilitate operation.
Above-described specific implementation mode, to the purpose of this utility model, technical solution and advantageous effect carried out into
One step is described in detail, it should be understood that the foregoing is merely specific embodiment of the present utility model, is not used to limit
