Abstract
Description
Technical Field
[0001] The present application relates to the technical field of air compressors, and in particular to an anti-stalling structure and an air compressor system. Background Art
[0002] At present, existing air compressors have stalling problems due to various reasons, for example, stalling caused by severe blockage of the air inlet. When the air inlet is severely blocked, the air cannot fully enter the cylinder of the air compressor, causing the internal pressure of the cylinder to rise sharply, which in turn causes stalling. For another example, the stalling problem caused by poor lubrication. If the lubrication is poor, it will cause the machine to generate heat during operation, causing serious internal wear, and then causing the machine to stagnate. For another example, a motor failure causes the air compressor to stall. The motor coil burns out, the power supply fails, etc., which may cause the motor to operate abnormally, resulting in a stall. In general, stalling can be prevented by cleaning the air inlet, checking the lubrication system, checking the motor, etc., but it is difficult to solve the problem fundamentally. It is urgent to modify the structural design of the existing air compressor.
[0003] Therefore, it is desired to provide an anti-jamming structure and an air compressor system, which can solve the jamming problem during the start-up of the air compressor by tilting the return valve plate, spring, vent hole and other structures, ensure the effective start-up of the air compressor, and increase the effective operation time of the air compressor.

[0005] In some embodiments, the gas circulation path of the air compressor flows from the exhaust chamber through the return valve plate and back to the intake chamber through the vent hole.
[0006] In some embodiments, a vertical position of a connection between one end of the vent hole and the exhaust cavity through the return valve sheet is lower than a vertical position of a connection between the other end of the vent hole and the intake cavity.
[0007] In some embodiments, the spring seat has a diameter different from a diameter of the vent hole.
[0008] In some embodiments, the length of the spring seat in the expansion and contraction direction of the spring is smaller than the length of the spring in an unexpanded state.

[0010] In some embodiments, the fixing screw is located inside the cylinder head, and a nut corresponding to the fixing screw is located inside the exhaust chamber.
[0011] In some embodiments, when the air compressor is started, the return valve plate is in a lifted state due to the spring force of the spring, with a gap between the return valve plate and the cylinder head, so that the gas in the exhaust chamber flows back to the intake chamber.

[0023] The embodiment of the present application provides an anti-stalling structure and an air compressor system. In order to facilitate understanding of the embodiment of the present application, the embodiment of the present application will be described in detail below with reference to the accompanying drawings.
[0024] Figure 1 is an exemplary structural diagram of an anti-stalling structure provided according to some embodiments of the present application. Figure 1 As shown, the anti-jamming structure is arranged in an air compressor, including an exhaust chamber, an intake chamber, a cylinder head, a spring, a return valve plate, a fixing screw, and a vent hole of the air compressor, wherein the spring is arranged on a spring seat and is arranged in the vent hole together with the return valve plate; the vent hole connects the exhaust chamber and the intake chamber; the vent hole and the fixing screw are arranged parallel to each other, forming an inclined angle with the horizontal top surface of the cylinder head; the return valve plate is arranged at the connection point between the vent hole and the exhaust chamber, and when the return valve plate is in a lifted state, there is a gap between the return valve plate and the cylinder head, and the exhaust chamber is connected to the intake chamber; when the return valve plate is in a closed state, there is no gap between the return valve plate and the cylinder head, and the exhaust chamber is not connected to the intake chamber.
[0025] According to some embodiments of the present application, the gas circulation path of the air compressor flows from the exhaust chamber through the return valve plate and returns to the intake chamber through the vent hole.
[0026] In some embodiments, the position of one end of the vent hole through the return valve plate and the exhaust cavity in the vertical direction is lower than the position of the other end of the vent hole and the intake cavity in the vertical direction. As an example, due to the vertical position difference, the gas in the exhaust cavity can effectively flow back to the intake cavity to form a gas circulation path.
[0027] In some embodiments, the diameter of the spring seat is different from the diameter of the vent. In some embodiments, the length of the spring seat in the direction of the spring expansion and contraction is less than the length of the spring in the unexpanded state. As an example, the difference between the diameter of the spring seat and the diameter of the vent can be used to control the lifting or closing state of the return valve plate by the expansion and contraction of the spring in the direction of the spring expansion and contraction. For another example, the length of the spring is less than the length of the spring seat, and the expansion and contraction of the spring can be used in the direction of the spring expansion and contraction to control the state of the return valve plate. For another example, when the internal pressure is restored, the spring returns.
[0028] In some embodiments, the position of the fixing screw in the vertical direction is higher than the position of the return valve plate in the vertical direction. In some embodiments, the fixing screw is located inside the cylinder head, and the nut corresponding to the fixing screw is located inside the exhaust chamber. As an example, the position of the fixing screw is designed to facilitate actual installation.
[0029] In some embodiments, the flow rate of the gas circulation path is adjusted by adjusting the gap between the return valve plate and the cylinder head, and the vent hole, etc. For example, the flow rate of the gas circulation path is adjusted by adjusting the aperture size of the vent hole. For another example, the flow rate of the gas circulation path is adjusted by adjusting the elastic force of the spring.
[0030] In some embodiments, the closing time of the return valve plate is adjusted by adjusting the aperture size of the vent hole. In another example, the closing time of the return valve plate is adjusted by adjusting the elastic force of the spring.
[0031] According to some embodiments of the present application, when the air compressor is started, the return valve plate is in a lifted state due to the spring force of the spring, and there is a gap between the return valve plate and the cylinder head, and the gas in the exhaust chamber flows back to the intake chamber. Furthermore, when the speed of the main motor of the air compressor reaches 70% or more of the rated speed, the internal pressure of the exhaust chamber increases, there is no gap between the return valve plate and the cylinder head, and the exhaust chamber is not connected to the intake chamber, so that the air compressor can work normally.
[0032] According to some embodiments of the present application, the anti-rotation blocking structure may further be provided with an intake valve plate, which is provided at the bottom of the intake chamber in the vertical direction, and the bottom is connected to the piston upper air pressure chamber. As an example, the intake valve plate may be opened by the gas flowing back from the exhaust chamber to the intake chamber, and enter the bottom of the exhaust chamber in the vertical direction through the piston upper air pressure chamber, forming a gas circulation path.
[0033] Figure 2 is an exemplary structural diagram of an air compressor gas circulation path provided according to some embodiments of the present application. Figure 2 As shown, the gas circulation path of the air compressor flows from the exhaust chamber through the return valve plate and back to the intake chamber through the vent hole. The gas in the intake chamber enters the upper compression chamber of the piston through the intake valve plate and then enters the exhaust chamber.
[0034] According to some embodiments of the present application, an air compressor system is provided, which adopts the anti-stall structure, and the anti-stall structure is arranged in the air compressor, including an exhaust chamber, an intake chamber, a cylinder head, a spring, a return valve plate, a fixing screw, and a vent hole of the air compressor, wherein the spring and the return valve plate are arranged in the vent hole; the vent hole connects the exhaust chamber and the intake chamber; the vent hole and the fixing screw are arranged parallel to each other, and form an inclined angle with the horizontal top surface of the cylinder head; the return valve plate is arranged at the connection between the vent hole and the exhaust chamber, and when the return valve plate is in a lifted state, there is a gap between the return valve plate and the cylinder head, and the exhaust chamber is connected to the intake chamber; when the return valve plate is in a closed state, there is no gap between the return valve plate and the cylinder head, and the exhaust chamber is not connected to the intake chamber, so as to solve the stall problem when the air compressor is started, ensure the effective start-up of the air compressor, and increase the effective operation time of the air compressor.

[0036] Figure 1 is an exemplary structural diagram of an anti-stalling structure provided according to some embodiments of the present application.

The diameter of the spring seat is different from the diameter of the vent hole 5. In some embodiments, the length of the spring seat in the expansion and contraction direction of the spring 2 is less than the length of the spring 2 in the unexpanded state.

The gas in the intake chamber enters the upper compression chamber of the piston through the intake valve plate (opened by the gas flowing back from the primary compression exhaust chamber), and then enters the exhaust chamber (primary exhaust chamber). In some embodiments, the air compressor may further include an intake valve plate for primary compression, etc.

For example, the vents and fixing screws of the anti-jamming structure can be set at different inclination angles, etc. Such deformations are all within the scope of protection of the present application.
[0040] In summary, the anti-jamming structure of the present application solves the jamming problem during the start-up of the air compressor by tilting the return valve plate, spring, vent hole and other structures, thereby ensuring the effective start-up of the air compressor and increasing the effective operation time of the air compressor.
