All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention is further described below with reference to the accompanying drawings.

In a specific embodiment of the present invention, referring to fig. 1-6, a motor-rotor integrated eccentric pump comprises: the device comprises a first cylinder body 1, a second cylinder body 24, a middle partition plate 21, a crankshaft 3, a power rotor 5, a liquid discharging rotor 4, a water pump cover plate 22 and a motor cover plate 23;

an intermediate partition plate 21 is arranged between the first cylinder body 1 and the second cylinder body 24; the motor cover plate 23 is arranged at the other side of the first cylinder 1 body;

the motor cover plate 23 is provided with an exhaust gas discharge passage 13;

the first cylinder body is provided with a spark plug 14 and an oil nozzle 16;

the water pump cover plate 22 is arranged on the other side of the second cylinder body, the liquid discharging rotor 4 is arranged in the second cylinder body 24, and a liquid inlet and outlet channel is arranged on the second cylinder body 24.

In the embodiment of the invention, see fig. 1-6, further comprising a combustion chamber 2, the combustion chamber 2 is composed of a first cylinder 1, a middle partition 21 and a motor cover plate 23, and a power rotor 5 is installed in the combustion chamber 2.

In the embodiment of the invention, as shown in fig. 1-6, the power rotor 5 and the liquid drainage rotor 4 are connected with the crankshaft 3 through bearings, when the power rotor and the liquid drainage rotor are installed, the middle partition plate 21 penetrates through a small hole in the middle of a small eccentric position 18 of the crankshaft 3, then the power rotor 5 is installed at a large eccentric position 17, and the liquid drainage rotor 4 is installed at a small eccentric position.

In the embodiment of the invention, as shown in fig. 1-6, a first cylinder body 1, a second cylinder body 24, a middle partition plate 21, a water pump cover plate 22 and a motor cover plate 23 are connected by bolts, a sealing elastic sheet 12 is arranged on the end surface of a power rotor 5, and an O-shaped sealing ring 10 is arranged on the end surface of a liquid discharge rotor 4.

In the embodiment of the present invention, as shown in fig. 1 to 6, a mechanical seal is installed between the first cylinder 1 and the intermediate partition 21, and a mechanical seal is installed between the second cylinder 24 and the intermediate partition 21.

In the embodiment of the invention, shown in fig. 1-6, the large eccentricity 17 and the small eccentricity 18 of the crankshaft 3 are arranged at 180 °, and the large eccentricity 17 is located at the same eccentricity as the small eccentricity 1.

In a particular embodiment of the invention, see fig. 1-6, the tapping rotor edge 9 divides the first cylinder 1 into 3 liquid chambers 6. The power rotor side arc 11 divides the combustion chamber 2 into 3 air chambers 15.

The specific working process is as follows: the crankshaft 3 is shaken by an external force to rotate the power rotor 5 in the combustion chamber 2. When the power rotor 5 rotates to form the maximum air cavity 15 with the combustion chamber 2, the combustion chamber 2 sucks air through the air suction channel on the side wall and is fully mixed with gasoline sprayed by the oil nozzle 16. After that, the power rotor 5 continues to rotate, the oil-gas mixture is continuously compressed, and after reaching a certain pressure, the spark plug is triggered to ignite and ignite the oil-gas mixture, so that the gas pressure acting on the cambered surface of the power rotor 5 pushes the rotor to continue rotating, thereby driving the crankshaft 3 to continue rotating, and the waste gas generated in the oil-gas combustion process is discharged from the combustion chamber through the waste gas discharge channel 13. The rotation of bent axle 3 and then drives flowing back rotor 4 and do eccentric rotation in first cylinder body 1, realizes the start-up of motor rotor integral type eccentric rotor water pump, has just so realized that the power supply passes through same bent axle with the water pump and is connected, need not a series of devices such as shaft coupling, reduction gear, has reduced mechanical loss, has also reduced the complexity of water pump unit lectotype simultaneously.

When the liquid discharging rotor 4 and the cylinder body 1 form the maximum liquid cavity 6, the cylinder body 1 sucks water through the water inlet channel 8, the crankshaft 3 drives the liquid discharging rotor 4 to continue rotating, the sucked water is continuously compressed, and finally the cylinder body is discharged through the water outlet channel 7 to realize the water sucking and discharging function of the water pump. And in the process, the liquid conveyed in the pump takes away the heat generated by the combustion of the oil gas, so that the temperature of the combustion chamber 2 is reduced. Two sides of the first cylinder body 1 are respectively provided with a water outlet channel 7 and a water inlet channel 8, so that the water suction and drainage efficiency is improved. In order to ensure that the liquid in the first cylinder 1 does not leak into the combustion chamber 2, a mechanical seal 20 is arranged at the central hole of the side plate shared by the combustion chamber 2 and the cylinder 1.

The lowest bottom of the cylinder body 1 is provided with a drain port 19, the drain port 19 is communicated with the cylinder body 1, and solution in the cylinder body cavity needs to be drained when the equipment is idle or stops for a long time, so that the equipment is prevented from rusting.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
