Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engine accessories, in particular to a carburetor which is easy to operate. Background Art
[0002] The carburetor is a device on the engine used to mix a certain proportion of gasoline and air. It is an important part of the engine. The carburetor includes a carburetor body, a mixing chamber formed on the carburetor body, and a choke in the mixing chamber. The choke is used to control the amount of air entering. In traditional engines, the choke switch is installed on the carburetor, and the throttle switch and the flameout switch are installed at other locations of the engine. When in use, the throttle switch, the flameout switch, and the choke switch need to be controlled separately, and there are many operating actions. In addition, the installation positions of the throttle switch, the flameout switch, and the choke switch are relatively scattered, and the movement range is large, which is inconvenient to operate. Utility Model Content
[0003] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a carburetor that is easy to operate, so as to solve the problems of multiple operating actions, large operating range and inconvenient operation during the start and stop process of the current engine.
[0004] The technical solution adopted by the utility model is as follows:
[0005] A carburetor that is easy to operate includes a carburetor body, in which a choke is arranged, a throttle switch, a flameout switch, a first drive component for controlling the opening of the choke, a linkage structure for linkage control of the throttle switch and the flameout switch, and a second drive component for controlling the linkage structure, wherein the first drive component and the second drive component rotate coaxially.
[0006] Compared with the prior art, the principles and beneficial effects of the utility model are as follows:
[0007] A choke, a throttle switch and a flameout switch are provided on the carburetor body. The first drive assembly controls the choke, and the second drive assembly controls the throttle switch and the flameout switch in linkage by controlling the linkage structure. Since the first drive assembly and the second drive assembly rotate coaxially, when operating the engine start and stop, only one hand needs to be placed on the position of the first drive assembly and the second drive assembly. By operating the first handle and the second handle, the choke, the throttle switch and the flameout switch can be controlled. Compared with the prior art that needs to switch to different places and control the throttle switch, the flameout switch and the choke switch separately, this solution is not only more compact in structure, can reduce the operating range, and is more convenient to operate, but also by setting the throttle switch and the flameout switch as an integrated control, it can also reduce operating actions and has strong practicality.
[0008] As a preferred embodiment of the utility model, the throttle switch includes a throttle shaft for controlling the opening and closing of the throttle, and the linkage structure includes a first arm arranged on the throttle shaft, the first arm rotates to drive the throttle shaft to rotate to control the throttle to be closed and to contact and cooperate with the flameout switch to turn off the engine, and the first arm rotates to drive the throttle shaft to rotate to control the throttle to be opened and separated from the flameout switch to start the engine. In this scheme, the first arm rotates to drive the throttle shaft to rotate, and the throttle shaft controls the opening and closing of the throttle. When the throttle is closed, the first arm just contacts the flameout switch to meet the flameout requirement of the engine. When the throttle is open, the first arm is separated from the flameout switch to meet the starting requirement of the engine. By rotating the first arm, the integrated control of the throttle switch and the flameout switch can be realized, which not only simplifies the operation action and makes the operation more convenient, but also effectively avoids the problem of the engine failing to start normally due to operating errors or missed operations through integrated control.
[0009] As a preferred embodiment of the utility model, the second driving assembly includes a first driving arm for driving the first arm to rotate, the first arm is provided with a first strip hole, the first driving arm is provided with a first connecting rod, and the first connecting rod is slidably fitted in the first strip hole. In this solution, when the first connecting rod is slidably fitted in the first strip hole, the contact area between the first connecting rod and the first strip hole is two lines, and the contact surface of the line contact is small, which can reduce sliding friction, make the drive smoother, and facilitate the drive between structures. In addition, this driving structure is simple and compact, with a small overall size, which is also conducive to the arrangement and lightweight design of various components on the carburetor.
[0010] As a preferred embodiment of the utility model, the choke is provided with a choke shaft that rotates synchronously therewith, the choke shaft is provided with a second arm, the second arm is provided with a second strip hole, the first drive assembly includes a second drive arm, and the second drive arm is provided with a second connecting rod that slides in the second strip hole. In this solution, the second drive arm rotates with the first handle, and the rotation of the second drive arm causes the second connecting rod to slide in the second strip hole, thereby driving the second arm to rotate.
[0011] As a preferred embodiment of the utility model, the first connecting rod and the second connecting rod are both covered with a protective cover with a smooth outer surface. In this solution, by arranging a protective cover on the outer surface of the first connecting rod and the second connecting rod, the protective cover can protect the first connecting rod and the second connecting rod, and prevent the first connecting rod and the second connecting rod from being damaged due to long-term friction with the inner wall of the first strip hole and the second strip hole. On the other hand, the smooth outer surface of the protective cover can make the first connecting rod and the second connecting rod more smooth when sliding and fitting, thereby ensuring the stability and smoothness of the driving process.

The flameout switch 15 is arranged on the rotation path of the first arm 13. When the first arm 13 rotates and drives the throttle shaft 12 to rotate to control the throttle to close, the outer edge of the first arm 13 contacts and cooperates with the starting piece 16 of the flameout switch 15 to shut down the engine. When the first arm 13 rotates and drives the throttle shaft 12 to rotate to control the throttle to open, the outer edge of the first arm 13 separates from the starting piece 16 of the flameout switch 15 to start the engine.
[0020] The first connecting rod 11 and the second connecting rod 8 are both covered with protective covers, which are made of stainless steel and have a smooth outer surface.
