[0002] A carburetor is a mechanical device that converts liquid fuel (such as gasoline) into combustible gas so that it can enter the internal combustion engine for combustion. It plays an important role in the engine and can be called the "heart" of the engine. A diaphragm carburetor usually consists of a mixing chamber, an intake pipe and an oil inlet pipe. It transports air and fuel to the mixing chamber for mixing and supplies them to the internal combustion engine for combustion, allowing the engine to operate normally.

[0003] For example, a patent entitled: A simple diaphragm carburetor (patent application number: CN202321569114.9) discloses a simple diaphragm carburetor. By setting a filter plate that can slide up and down, it can effectively filter impurities and particulate matter in the air, prevent impurities and particulate matter from adhering to the inside of the carburetor, and reduce the service life of the carburetor. However, when the filter plate is pulled up from the filter box, dust and impurities adhering to one side of the filter plate will fall into the filter box and form an accumulation. When wind passes through, the dust will be blown into the carburetor, resulting in unclean cleaning.

[0004] Therefore, it is necessary to propose a diaphragm type carburetor assembly to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The utility model provides Figure 1 to Figure 5 A diaphragm carburetor assembly is shown, comprising a carburetor body 1 and a filter assembly arranged on one side of the carburetor body 1, an air intake pipe 7 is arranged on the side of the filter box 5 away from the carburetor body 1, the air intake pipe 7 is connected to the inside of the filter box 5, and a solenoid valve 6 is arranged on the air intake pipe 7, and the other side of the filter box 5 is connected to the inside of the carburetor body 1.

[0025] The top of the carburetor body 1 is rotatably connected to a rotary valve 4 through a sealed bearing. The rotary valve 4 and the sealed bearing cooperate with each other to control the flow of fuel in the carburetor body 1. The sealed bearing is used to maintain the stable rotation of the rotary valve 4. The bottom of the carburetor body 1 is connected to a storage tank 3. A nozzle 2 is provided on one side of the carburetor body 1. During operation, when the carburetor body 1 has no fuel, fuel is transported to the carburetor body 1 through the oil inlet pipe, and the flow rate of the fuel is controlled by the nozzle 2 to ensure that the fuel can enter the carburetor body 1 at an appropriate speed and in a suitable direction.

[0026] The filter assembly includes a filter box 5, a top plate 8 is provided at the top of the filter box 5, at least two filter screens 14 are connected to the bottom of the top plate 8, a collecting box 19 is fixed to one side of the bottom of the two filter screens 14, a spacing is left between the two filter screens 14, and a rotating plate 15 is rotatably connected between the two sides of the inside of the filter box 5, a sponge block 16 is fixed to one side of the rotating plate 15, and one side of the sponge block 16 is attached to the surface of the filter screen 14 away from the carburetor body 1.

[0027] In the actual operation of the present invention, by providing at least two filter screens 14, the filtering effect can be improved, and when air is input into the filter box 5, dust intercepted by the filter screens 14 in the air falls and is collected by the collection box 19 to prevent dust from scattering.

[0028] When the filter box 5 is opened, the top plate 8 can be pulled up to drive the two filter screens 14 to move upward. When the two filter screens 14 move upward, the side of the filter screen 14 close to the air inlet pipe 7 will contact and rub with the sponge block 16, so that the filter screen 14 is cleaned down, and because a collection box 19 is provided, the fallen dust and impurities will be collected by the collection box 19. Since the friction force is small, it will not affect the rotation of the rotating plate 15, thereby automatically completing the cleaning and collection work. When the collection box 19 moves to the bottom end of the rotating plate 15, the pulling force is large, and the collection box 19 pushes the rotating plate 15 to rotate, and does not prevent the collection box 19 from moving out of the filter box 5.

[0029] Furthermore, when wind enters from the inside of the air inlet pipe 7, since the filter plate 14 and the inside of the filter box 5 are in a plug-in state, when the wind blows, the action of the wind will cause the filter plate 14 and the plug-in position to vibrate, causing the filter plate 14 to move up and down, and with the friction between the filter plate 14 and the rotating plate 15, the rotating plate 15 will rotate up and down, and the action of the torsion spring will reset the rotating plate 14, reducing the amplitude of the up and down rotation of the rotating plate 14, so that the up and down movement amplitude of the filter plate 14 can be reduced through friction.

[0030] The rotating plate 15 is rotatably connected to the inside of the filter box 5 via a rotating shaft, and a torsion spring is provided on the rotating shaft. The rotating plate 15 and the filter screen plate 14 are distributed at a vertical angle.

[0031] The personnel only need to dump the dust inside the collection box 19 removed from the filter box 5. The cleaning work saves time and effort and is highly efficient. When the collection box 19 is removed from the filter box 5, the rotating plate 15 is automatically reset by the action of the torsion spring and is parallel to the bottom end of the filter box 5.

[0032] Slide blocks 18 are fixed at both ends of the filter screen plate 14, and slide rails 17 for the slide blocks 18 to slide through are fixed on both sides of the filter box 5. The slide rails 17 are distributed along the length direction of the filter box 5. By providing the slide rails 17, the slide blocks 18 on both sides of the filter screen plate 14 can be easily plugged in and slid, thereby improving the stability of the filter screen plate 14 sliding up and down.

[0033] A groove 12 is provided at the top of the top plate 8, and a rotating handle 13 is rotatably connected inside the groove 12. The rotating handle 13 can facilitate a person to pull the top plate 8 upward.

[0034] Connecting plates 9 are fixed on both sides of the top plate 8, and fixing plates 10 corresponding to the positions of the connecting plates 9 are fixed on the top ends of both sides of the filter box 5. Fixing bolts 11 are arranged between the connecting plates 9 and the corresponding fixing plates 10. The fixing bolts 11 can fix the top plate 8 and the filter box 5 to avoid looseness between the top plate 8 and the filter box 5.
