SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an energy-conserving premix structure of booster-type of engine to solve the unnecessary gas outgoing's that prior art two-stroke engine exists problem.
In order to achieve the above purpose, the utility model discloses the technical scheme who adopts is:
the utility model provides an energy-conserving premix structure of booster-type of engine, including the box of crankcase, and communicate in the cylinder body of the cylinder of box rotates in the box and installs the bent axle, install the flabellum on the bent axle, the cylinder wall of cylinder body is equipped with reservoir, lower air flue, last air flue, the reservoir passes through the air flue and is close to cylinder body tip position intercommunication in the cylinder body, lower air flue one end communicates to reservoir, the other end communicates to the position that corresponds the flabellum in the box, last air flue one end communicates to the cylinder body, the other end communicates to the box in.
Further, an air inlet pressure valve is arranged in an air passage between the air storage chamber and the cylinder body.
Furthermore, an exhaust pressure valve is arranged at one end of the lower air passage communicated to the air storage chamber.
The utility model discloses, increased the gas receiver in the cylinder, the mist that gets into the cylinder has in the small part gets into the gas receiver, leads to the air flue under the gas receiver, can make the mist spout in the box.
Meanwhile, the fan blades are arranged on the crankshaft, and the lower air flue opening is opposite to the fan blades, so that the mixed gas impacts the fan blades to rotate, and the boosting force is formed to drive the crankshaft to rotate in an accelerating mode, and therefore the performance of the engine is improved.
When the mixed gas in the box body reaches a certain degree, the mixed gas can flow back into the cylinder through the upper air passage.
Because the mixed gas is in a premixed state, the pressure in the cylinder is increased, energy and oil are saved, and the premixed mixed gas is combusted more fully, so that the power is improved, and energy and emission are saved.

Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1 and 2, the utility model relates to an energy-conserving premix structure of booster-type of engine, including the box 1 of crankcase to and communicate in the cylinder body 2 of the cylinder at box 1 top, the horizontal bent axle 3 of axial is installed to the internal rotation of box 1, and vertical slidable mounting has piston assembly 4 in the cylinder body 2, and piston assembly 4 passes through the piston rod and is connected with bent axle 3.
The right side of the crankshaft 3 is fixedly provided with fan blades 5 which rotate synchronously with the crankshaft 3. An air storage chamber 6 is arranged at the upper part of the right side cylinder wall of the cylinder body 2, a lower air passage 7 is arranged below the air storage chamber 5 at the right side cylinder wall of the cylinder body 2, and an upper air passage 8 is arranged at the lower part of the left side of the cylinder body 2.
The left side of the air storage chamber 6 is communicated with the upper part in the cylinder body 2 through an air passage, the position close to the end part of the cylinder body is communicated, and an air inlet pressure valve 9 is arranged in the air passage. The upper end of the lower air passage 7 is communicated to the bottom in the air storage chamber 6, an exhaust pressure valve 10 is arranged in the upper end of the lower air passage 7, and the lower end of the lower air passage 7 is communicated to the position, corresponding to the right side of the crankshaft 3, of the box body 1, and the fan blades 5 are arranged. The upper end of the upper air passage 8 is communicated to the lower part of the cylinder body 2, and the lower end of the upper air passage 8 is communicated to the left side of the tank body 1.
As shown in fig. 3, during the intake process, air and fuel oil are mixed through the carburetor to form a mixed gas which enters the cylinder body 2, when the piston assembly 4 reaches the top dead center, the mixed gas is compressed, and when the pressure in the cylinder reaches a certain degree, the intake pressure valve 9 is opened, so that a small part of the mixed gas enters the air storage chamber 6.
As shown in fig. 4, during the exhaust process, when the mixed gas in the gas storage chamber 6 reaches a certain degree, the pressure in the gas storage chamber 6 is greater than the pressure in the combustion chamber of the cylinder 2, the intake pressure valve 9 will be closed, and the exhaust pressure valve 10 will be opened, so that the mixed gas in the gas storage chamber 6 will enter the box body 1 through the lower air passage 7.
The fan blades 5 are arranged on the crankshaft 3, the lower air passage 7 is opposite to the fan blades 5, and the mixed gas in the air storage chamber 6 impacts the fan blades 5 through the lower air passage 7 under the action of pressure, so that the crankshaft 3 runs at a high speed.
In the exhaust process the utility model has the following advantages of two points:
the crankshaft 3 is accelerated by 1.5 times compared with the crankshaft in a normal state, so that the performance of the engine is improved.
Due to the effect of the mixed gas, the crankshaft 4, the fan blades 5, the bearings, the oil seals and the like in the box body 1 are lubricated, internal parts of the engine are maintained, and the service life of the engine is prolonged.
As shown in fig. 5, in the air returning process, after the mixed gas in the box 1 reaches a certain degree, when the piston assembly 4 reaches the bottom dead center, the mixed gas will flow back into the cylinder 2 through the upper air passage 8;
the air return process the utility model has the following two advantages:
the premixed gas flows back into the cylinder body 2 because the premixed gas is already in a premixed state, can be fully combusted, reduces the amount of waste gas, and plays a role in energy conservation and emission reduction;
