Manual choke flap switch：Carburetor carries choke door-plate, passes through choke linkage, manual switch choke.When dynamic
When power is used for grass trimmer, the operation handle of grass trimmer has a certain distance apart from choke flap switch, and switch choke is not especially square
Just, and may forget to operate choke and cause machine that can not start.
Enriching pump configuration：When being pumped with enriching, the without hindrance air door plate of carburetor, cold needs to pump by enriching when starting.Work as power
During for grass trimmer, the operation handle of grass trimmer has a certain distance apart from enriching pump, and manual enriching is especially inconvenient, in addition,
Enriching number is improper, and also easily causing machine can not start.
Actual use for the convenience of the user, it is necessary to which a set of mechanism can be such that choke is carried out certainly according to the actual needs of machine
The switch of dynamic adjusting choke.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of engine automatic choke valve, when starting machine
Manual control switch's choke is not required, avoids faulty operation and causes machine that can not start.
In order to solve the above technical problems, the technical solution that the utility model uses is：It is automatic to provide a kind of engine
Choke gear, including：Temperature control sensor, muffler for motor, connecting rod and carburetor are provided on the temperature control sensor
One swing arm, the temperature control sensor are arranged on muffler for motor, and the carburetor includes a choke, the connection
The front end of bar is connected with the swing arm on temperature control sensor, and the rear end of connecting rod is connected with the choke of carburetor, the temperature
Swing arm is rotated and pulls connecting rod when control sensor is heated, opens choke.
In one preferred embodiment of the utility model, the input terminal of the temperature control sensor is fitted in muffler for motor
Surface is extended to inside muffler for motor.
In one preferred embodiment of the utility model, mounting hole, the front end of the connecting rod are provided in the swing arm
Bending is extended in mounting hole.
In one preferred embodiment of the utility model, the front end of the connecting rod is fixed using pin.
In one preferred embodiment of the utility model, the connecting rod is curve stiff rod.
In one preferred embodiment of the utility model, the temperature control sensor, which is assemblied on muffler for motor, forms one
A component.
The beneficial effects of the utility model are：A kind of engine automatic choke valve that the utility model is pointed out, passes through
The temperature of muffler for motor realizes the variation of thermistor in temperature control sensor, realizes the swing arm movement of temperature control sensor, even
Extension bar realizes automatically opening for choke, simplifies starting step, avoid with the mobile opening of swing arm or closing choke
Maloperation.
Description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Other attached drawings are obtained, wherein：
Fig. 1 is a kind of structure diagram of one preferred embodiment of engine automatic choke valve of the utility model.
Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only the part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment that those of ordinary skill in the art are obtained without making creative work belong to
The scope of the utility model protection.
Referring to Fig. 1, the utility model embodiment includes：
A kind of engine automatic choke valve, including：Temperature control sensor 1, muffler for motor 2, connecting rod 3 and carburetion
Device 4 is set there are one swing arm on the temperature control sensor 1, and the temperature control sensor 1 is arranged on muffler for motor 2, described
The input terminal of temperature control sensor 1 is fitted in 2 surface of muffler for motor or extends to inside muffler for motor 2, engine
After startup, muffler for motor 2 is heated, the thermistor variation of temperature control sensor 1, and carries out the driving of swing arm.
The carburetor 4 includes a choke, and the front end of the connecting rod 3 is connected with the swing arm on temperature control sensor 1
Connect, the rear end of connecting rod 3 is connected with the choke of carburetor 4, when the temperature control sensor 1 is heated swing arm revolved counterclockwise
Then connecting rod 3 is pulled, choke is opened, realizes automation control, during cold start-up, the swing arm of temperature control sensor 1 is resetted and protected
Hold the closing of choke.
Mounting hole is provided in the swing arm, the front end bending of the connecting rod 3 is extended in mounting hole, easy for installation.
The front end of the connecting rod 3 is fixed using pin, avoids the problem that loosens that connecting rod 3 is connected with swing arm, after connecting rod 3
End can also use similar structure and be connected with choke, and structural stability is good.
The connecting rod 3 is curve stiff rod.Curvilinear structures can avoid the parts thereof on engine, not influence other
The installation and work of part.
The temperature control sensor 1 is assemblied in one component of formation on muffler for motor 2, easy for installation, and does not increase
