Description

Technical Field

[0001] The utility model relates to the technical field of carburetors, and particularly relates to a carburetor with double-chamber alternating fuel inlet. Background Technique

[0002] A carburetor is a device used in gasoline engines. Its function is to convert liquid fuel (such as gasoline) into fuel atomization so as to be mixed with air and then sprayed into the cylinder for combustion. By sucking in air and liquid fuel, a combustible gas is formed therein, and then it is sent into the cylinder to be mixed with air and ignited, so that the engine can operate normally.

[0003] In the prior art, a Chinese patent with the publication number CN108894895A discloses a carburetor, which includes a carburetor body. The carburetor body includes a plunger channel, an air inlet chamber, a mixing chamber and a fuel chamber. The air inlet chamber is provided with an air inlet, an idling and low-speed air inlet pipe and a choke valve. The mixing chamber is provided with a mixed gas outlet. The fuel chamber is communicated with the mixing chamber through a main fuel pipe. A needle valve is arranged between the plunger channel and the main fuel pipe. An atmosphere channel, a float valve sub-assembly and an idling fuel supply system are arranged in the fuel chamber. One end of the air inlet channel is communicated with the fuel chamber, and the other end is communicated with the air inlet chamber. The float valve sub-assembly is arranged at one end where the atmosphere channel is communicated with the fuel chamber. The idling fuel supply system includes an idling and low-speed fuel pipe and a mixture ratio screw, and the idling and low-speed fuel pipe is communicated with the idling and low-speed air inlet pipe; this carburetor changes the air intake amount, so as to be applicable to alcohol-based fuel, and the improvement is simple, solving the problem that the existing carburetor cannot burn when using fuel with a low calorific value.

[0004] The above-mentioned device only has one mixing chamber (i.e., single-chamber operation). In the actual use process, when the single-chamber repeats operation and the frequency increases, there may be a situation of insufficient air intake. At this time, the fuel-air mixing effect is poor, affecting the utilization rate of gasoline, thereby reducing the power of the vehicle and increasing fuel consumption. Content of the Utility Model

[0005] The purpose of the utility model is to provide a carburetor with double-chamber alternating fuel inlet to solve the problem of insufficient fuel-air mixing in single-chamber operation proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A carburetor with double-chamber alternating fuel inlet, which includes a carburetor housing in a square structure. An oiling channel is opened inside the carburetor housing, and an inner pipe is fixedly installed at the middle position inside the oiling channel. The carburetor housing also includes:

[0007] A fuel storage tank is fixedly installed below the carburetor housing, and the fuel storage tank is communicated with the oiling channel. And an oil delivery pipe for delivering gasoline is fixedly installed on the side of the fuel storage tank;

[0008] On the left and right sides of the carburetor housing, an intake pipe and an exhaust pipe that are interconnected with the carburetion passage are fixedly installed respectively. And inside the carburetion passage, near the exhaust pipe position, an air outlet valve controlled by a micro motor is rotatably installed. And inside the carburetion passage, near the intake pipe position, an intake valve is rotatably installed. On the upper surface of the carburetor housing, a reciprocating mechanism for controlling the alternate operation of the two intake valves is provided.

[0009] Preferably, the reciprocating mechanism includes a transmission belt for driving the rotation of the intake valve and a torsion spring fixedly installed outside the rotation of the intake valve for driving its reset.

[0010] Preferably, the transmission belt is connected to a driven gear rotatably installed on the upper surface of the carburetor housing.

[0011] Preferably, a driving gear for driving its rotation is meshed and connected to the side of the driven gear, and the driving gear is provided with a semi-tooth-shaped structure.

[0012] Preferably, the driving gear is driven to rotate by a driving motor above it, and a protective cover for protecting the reciprocating mechanism is fixedly installed on the upper surface of the carburetor housing.

[0013] Preferably, a cleaning pipe is fixedly installed at the middle position of the upper surface of the carburetor housing, and the lower end of the cleaning pipe is interconnected with a pressurizing chamber opened inside the carburetor housing.

[0014] Preferably, equally spaced flushing holes are opened below the pressurizing chamber, and the flushing holes are interconnected with the carburetion passage.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Embodiment 1: Please refer to Figure 1 and Figure 2, in order to achieve the purpose of carburetion in this embodiment, the following technical solutions are provided, and specifically disclosed: a carburetor housing 1 with a square structure, a carburetion passage 2 is opened inside the carburetor housing 1, and an inner pipe 3 is fixedly installed at the middle position inside the carburetion passage 2. A fuel reservoir 4 is fixedly installed below the carburetor housing 1, and the fuel reservoir 4 is communicated with the carburetion passage 2. A fuel delivery pipe 5 for delivering gasoline is fixedly installed on the side of the fuel reservoir 4. An intake pipe 7 and an exhaust pipe 8 communicated with the carburetion passage 2 are respectively fixedly installed on the left and right sides of the carburetor housing 1. An exhaust gas valve 6 controlled by a micro motor 601 is rotatably installed at a position close to the exhaust pipe 8 inside the carburetion passage 2, and an intake valve 9 is rotatably installed at a position close to the intake pipe 7 inside the carburetion passage 2.

[0028] When using the device, first install the device in the engine. The intake pipe 7 is connected to the air filter end, and the exhaust pipe 8 is connected to the fuel injector end. When the engine starts, the micro motor 601 drives the exhaust gas valve 6 to rotate as needed, thereby adjusting the exhaust gas volume. At the same time, air enters the carburetion passage 2 from the intake pipe 7. When it reaches the inner pipe 3 with a smaller inner diameter, the flow rate increases and the pressure decreases. Thus, under the action of the pressure, the gasoline in the fuel reservoir 4 enters the carburetion passage 2 to be mixed and atomized with the air, and finally is discharged into the engine cylinder from the exhaust pipe 8.

[0029] Embodiment Two: Please refer to Figures 2 - 5 , in order to solve the problem of poor use effect of a single cavity in the traditional device in this embodiment, the following technical solutions are provided. A reciprocating mechanism is used to drive the two intake valves 9 to open and close alternately, thereby improving the utilization rate of gasoline through double-cavity operation. Specifically disclosed: a reciprocating mechanism for controlling the alternate operation of the two intake valves 9 is arranged on the upper surface of the carburetor housing 1. The reciprocating mechanism includes a transmission belt 11 for driving the intake valve 9 to rotate and a torsion spring 10 fixedly installed outside the rotation of the intake valve 9 for driving its reset. The transmission belt 11 is connected to a driven gear 12 rotatably installed on the upper surface of the carburetor housing 1. A driving gear 13 for driving its rotation is meshed and connected to the side of the driven gear 12, and the driving gear 13 is set as a semi-tooth structure. The driving gear 13 is driven to rotate by a driving motor 14 above it, and a protective cover 15 for protecting the reciprocating mechanism is fixedly installed on the upper surface of the carburetor housing 1.

[0030] During the operation of the device, the drive motor 14 inside the protective cover 15 is turned on and drives the driving gear 13 to rotate. The driving gear 13 drives the driven gear 12 engaged therewith to rotate, so that the driven gear 12 drives the intake valve 9 to rotate through the transmission belt 11. Since the driving gear 13 has a semi-tooth structure, only one intake valve 9 will rotate to the open state at a time, and the other intake valve 9 is in the closed state. When the engaged driven gear 12 switches, the other intake valve 9 rotates to the open state, and the original intake valve 9 is reset to the closed state under the action of the torsion spring 10. This reciprocation makes the two carburetor channels 2 work alternately.

[0031] Embodiment 3: Please refer to Figure 6 , in order to solve the problem that the traditional device is not convenient for internal cleaning, the following technical solutions are provided. Specifically disclosed are: a cleaning pipeline 16 is fixedly installed at the middle position of the upper surface of the carburetor housing 1, and the lower end of the cleaning pipeline 16 is communicated with a pressurization chamber 17 opened inside the carburetor housing 1. Flushing holes 18 are opened below the pressurization chamber 17 at equal intervals, and the flushing holes 18 are communicated with the carburetor channels 2.

[0032] When the device needs to be overhauled after being used for a period of time, after the overhaul is completed, the staff injects a cleaning agent into the pressurization chamber 17 through the cleaning pipeline 16. When the pressure increases, the cleaning agent in the pressurization chamber 17 is sprayed into the carburetor channels 2 from the lower flushing holes 18 to achieve the purpose of internal flushing, thereby extending the service life of the device.
