Description

Technical Field

[0002] A carburetor is a mechanical device that mixes a certain proportion of gasoline and air under the vacuum generated by the operation of the engine. As a precision mechanical device, the carburetor uses the kinetic energy of the inhaled air flow to achieve the atomization of gasoline. Its important role in the engine can be called the "heart" of the engine. The carburetor will automatically mix the corresponding concentration and output the corresponding amount of mixed gas according to the different working state requirements of the engine. A simple carburetor consists of three parts: the upper part has an air inlet and a float chamber, the middle part has a throat, a metering hole and a nozzle, and the lower part has a throttle, etc. The float chamber is a rectangular container that stores gasoline from the gasoline pump. There is a float in the container that uses the height of the float surface (oil level) to control the amount of oil entering. The oil inlet at one end of the nozzle in the middle is connected to the metering hole of the float chamber, and the oil outlet at the other end is at the throat of the throat.

[0024] See also Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, the enrichment valve type carburetor further includes a water spray assembly, which is arranged in the breather 1 and includes: Rotating ring 1 31, the inner wall of rotating ring 1 31 is slidably connected to the outer surface of threaded rod 18, the outer surface of threaded rod 18 is also slidably connected to rotating ring 2 34, the end surface of rotating ring 1 31 is fixedly connected to spring 1 32, one end of spring 1 32 away from rotating ring 1 31 is fixedly connected to the end surface of rotating ring 2 34, rotating ring 2 34 is hinged to the end surface of spring 1 32 away from the end surface of spring 1 32, and the other end of the curved rod 1 33 is hinged to a sliding block 1 37; A second sliding frame 36, the outer surface of the second sliding frame 36 is fixedly connected to the end surface of the piston sheet 15 facing one end of the threaded rod 18, the inner wall of the second sliding frame 36 is slidably connected to the surface of the first sliding block 37, the upper end surface of the first sliding block 37 is fixedly connected to the piston 24, the surface of the piston 24 is slidably connected to the second container 25, and the outer surface of the second container 25 is fixedly connected to the inner wall of the second sliding frame 36; A one-way valve 3 28, the inlet end of the one-way valve 3 28 is fixedly connected to the end of the container 2 25, and the outlet end of the one-way valve 3 28 is fixedly connected to a nozzle pipe 29, and the surface of the nozzle pipe 29 penetrates the surface of the piston plate 15; A one-way valve four 27, the outlet end of the one-way valve four 27 is fixedly connected to the surface of the container two 25, the inlet end of the one-way valve four 27 is fixedly connected to the fixed pipe one 26, the end of the fixed pipe one 26 away from the one-way valve four 27 is fixedly connected to the water storage part 30, the end face of the container one 16 is provided with a through slot, the slot wall of the slot is fixedly connected to the surface of the water storage part 30, and the end face of the water storage part 30 connected to the fixed pipe one 26 can be rotated, the end face of the water storage part 30 outside the container two 25 is fixedly connected to the water supply pipe 35, and the surface of the water supply pipe 35 passes through the inner wall of the ventilation cylinder 1.

[0025] In this embodiment, during the movement of the piston plate 15 away from the bottom end of the container 16, the end surface of the rotating ring 1 31 abuts against the inner wall of the container 16, so that during the movement of the piston plate 15, the bent rod 1 33 is first driven to deflect, and the sliding block 1 37 is further driven to slide in the sliding frame 2 36, thereby driving the piston 24 to move, thereby cooperating with the one-way flow of the one-way valve 3 28 and the one-way valve 4 27, and the water in the container 25 is sprayed out by the nozzle of the nozzle pipe 29 in atomized form. Furthermore, when the piston 24 moves to the bottom end of the container 25 and cannot move, the continued movement of the piston plate 15 will only drive the distance between the rotating ring 1 31 and the rotating ring 2 34 to decrease, thereby squeezing the spring 1 32; When the piston plate 15 moves toward the bottom end of the container 16, the pressure of the spring 132 is first released, so that the bent rod 133 remains unchanged. Then, when the pressure of the spring 132 is released, the piston plate 15 is started to move further, which drives the bent rod 133 to recover, and further drives the sliding block 137 to recover, so that the piston 24 slides to store water in the container 25. The setting of this water spray assembly has the following three advantages: Firstly, since the moving distance of the piston plate 15 remains unchanged, the amount of atomized water sprayed in can be quantitatively controlled, thereby preventing excessive liquid from causing excessive air humidity, thereby affecting the subsequent mixing ratio of the oil and liquid; Second, spraying water into the container 16 can make the dust floating in the air sink down, further reducing the dust content in the air, thereby reducing the dust entering the ventilator 1; Thirdly, spraying water into the container 16 can also wet the surface of the cleaning rod 13 , so that the cleaning rod 13 is more easily contaminated with dust during the rotation process, thereby further improving the cleaning effect of the cleaning rod 13 .

After contacting the inclined surface of the trapezoidal block 39, the trapezoidal block 39 is lowered outward, thereby squeezing the spring 2 40, further making the trapezoidal block 39 have an inward squeezing force to clamp the cleaning rod 13; The installation method of the assembly facilitates the installation of the cleaning rod 13, which indirectly facilitates the disassembly, cleaning or replacement of the cleaning rod 13, so that when there is too much dust on the cleaning rod 13, the cleaning rod 13 can be disassembled and cleaned more easily, further improving the practicality of the carburetor.
