Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, the self-unloading air compressor of the present invention comprises an air tank, a motor assembly 7 and a cylinder 5 driven by the motor assembly 7, wherein a piston 4 is arranged in the cylinder 5; a cylinder cover 1 is arranged on the cylinder 5, and a valve plate 3 is arranged between the cylinder cover 1 and the cylinder 5; a valve plate unloading hole 31 is formed in the valve plate 3, a cylinder cover unloading hole 11 is formed in the cylinder cover 1, a sealing gasket 2 made of flexible materials is arranged between the valve plate unloading hole 31 and the cylinder cover unloading hole 11, and a channel 21 for accommodating the sealing gasket 2 is formed between the cylinder cover 1 and the valve plate 3. The sealing gasket 2 can move in the channel 21 under the action of air pressure so as to block the valve plate unloading hole 31 or the cylinder cover unloading hole 11; the cylinder cover unloading hole 11 is communicated with the outside, and the valve plate unloading hole 31 is communicated with the cylinder 5; the cylinder cover 1 is communicated with the gas tank through an exhaust pipe 6. The cylinder 5 is provided with an unloading hole, and when the piston runs to a bottom dead center, high-pressure gas in the cylinder 5 can be discharged through the cylinder unloading hole. The exhaust pipe 6 is communicated with an unloading hole on the cylinder cover 1, and a one-way valve is arranged between the exhaust pipe 6 and the gas tank. The valve plate 3 is provided with an air hole, and an exhaust valve plate 8 capable of covering or releasing the air hole is arranged above the valve plate 3.
When the piston 4 moves upwards, the sealing gasket 2 seals the cylinder cover unloading hole 11 on the cylinder cover 1, so that high-pressure gas is not unloaded, and the flow loss is avoided; when the gas in the gas tank reaches the maximum pressure, the pressure switch cuts off the power supply, the piston 4 descends under the reaction force of the high-pressure gas in the cylinder 5 at the moment and finally stops at the lowest end, the sealing gasket 2 seals the valve plate unloading hole 31 on the valve plate 3 under the action of the negative-pressure gas in the cylinder, the cylinder cover unloading hole 11 is opened at the moment, redundant high-pressure gas in the cylinder cover 1 and the exhaust pipe 6 is released, and the high-pressure gas in the cylinder 5 is released through the unloading hole in the cylinder wall; when the engine is started again, the high-pressure gas in the cylinder 5, the cylinder cover 1 and the exhaust pipe 6 is discharged, so that the engine can be started under zero pressure.
When the air compressor is started for the first time, the pressures in the air cylinder 5, the cylinder cover 1 and the exhaust pipe 6 are all zero, the motor is started smoothly, and when the pressure in the air cylinder reaches the maximum set pressure, the pressure switch cuts off the power supply, and the machine stops working; at this time, the high-pressure gas in the cylinder 5, the cylinder cover 1 and the exhaust pipe 6 is discharged through the valve plate unloading hole 31 and the cylinder cover unloading hole 11, and a one-way valve is arranged between the exhaust pipe 6 and the gas tank, so that the gas pressure in the gas tank is still the maximum set pressure. And the pressure in the air tank still exists, and the starting is not influenced.
When the cylinder cover unloading device works normally, the cylinder cover unloading hole 11 on the cylinder cover 1 is sealed by the sealing gasket 2, so that high-pressure gas is not unloaded, and the flow loss is avoided; when the maximum pressure is reached, the pressure switch cuts off the power supply, the piston 4 descends under the reaction force of high-pressure gas in the cylinder at the moment and finally stops at a certain point at the lowest end, the sealing gasket 2 seals the valve plate unloading hole 31 on the valve plate 3 under the action of negative-pressure gas in the cylinder, the cylinder cover unloading hole 11 is opened at the moment, redundant high-pressure gas in the cylinder cover 1 and the exhaust pipe 6 is released, and the high-pressure gas in the cylinder 5 is released through the unloading hole in the cylinder wall; when the motor is started again, the high-pressure gas in the cylinder 5, the cylinder cover 1 and the exhaust pipe 6 is discharged, and the motor can be started at zero pressure.
