During the operation of an air compressor, the exhaust assembly plays a key role in controlling the discharge of compressed air, and its design is directly related to the efficiency and stability of the compressor. However, there are some defects in the traditional design, such as large valve resistance loss, slow closing speed, and large clearance volume, which affect the performance and energy efficiency of the compressor. Content of the Utility Model

[0003] The purpose of the utility model is to provide a compressor exhaust valve assembly and a compressor with a new double protection structure to solve the above technical problems.

[0004] To achieve the above purpose, the specific technical solutions of a compressor exhaust valve assembly and a compressor with a new double protection structure of the utility model are as follows:

[0005] A compressor exhaust valve assembly with a new double protection structure includes an exhaust valve seat, the exhaust valve seat is fixedly installed at the bottom of the exhaust valve position of the cylinder head, an exhaust valve plate is padded on the middle through hole of the exhaust valve seat, the upper surface of the exhaust valve plate abuts against the exhaust base through an exhaust spring, the upper end of the exhaust base abuts against an exhaust pressure nut through a base spring, and the exhaust pressure nut is threadedly connected to the upper end of the cylinder head of the compressor, and the screwing depth of the exhaust pressure nut can be adjusted by threads.

[0006] Further, a step portion is provided in the through hole of the exhaust valve seat, and the exhaust valve plate is padded on the step portion.

[0007] Further, the bottom of the exhaust base is communicated, and a plurality of exhaust holes are provided on the side surface.

[0008] Further, a spring seat is provided inside the exhaust base, the upper end of the exhaust spring is fixedly connected to the outer circumference of the spring seat, and the lower end is connected to the exhaust valve plate.

[0009] Further, a limiting column is provided at the upper end of the exhaust base, a limiting hole is provided inside the exhaust pressure nut, and the limiting column of the exhaust base is sleeved in the limiting hole of the exhaust pressure nut for limiting and fixing.

[0010] Further, a fixing seat for fixing the base spring is formed on the outer circumference of the limiting hole, the upper end of the base spring abuts against the bottom of the fixing seat, and the lower end abuts against the upper end of the exhaust base.

[0011] Further, a gap is formed between the base spring and the exhaust compression nut.

[0012] Further, the outer periphery of the exhaust compression nut has a thread and is threadedly connected to the valve port of the cylinder head.

[0013] The present utility model also discloses a compressor, including a cylinder block and a cylinder head. A piston assembly is provided in the cylinder block, and an intake valve assembly is provided on the cylinder head. The compressor includes the exhaust valve assembly described above.

[0014] The compressor exhaust valve assembly with a novel dual protection structure and the compressor of the present utility model have the following advantages:

[0015] 1. In this technical solution, by adding optimized structural configurations such as the exhaust compression nut, exhaust base, and base spring, the position and stability of the exhaust valve body can be adjusted more precisely, thereby reducing the unused space inside the cylinder head, that is, the clearance volume. The newly added components can improve the working performance of the air valve, make it close more tightly, further reduce the size of the gas passage, and reduce the clearance volume.

[0016] 2. Improve the response speed: The exhaust base and base spring added in this technical solution can provide more stable support, enabling the exhaust valve plate to respond more quickly to the pressure changes inside and outside the cylinder, thereby reducing the energy loss of the gas during the exhaust process.

[0017] 3. In this technical solution, the exhaust compression nut is mainly used to optimize the structural configuration of the exhaust valve body to ensure a closer fit, thereby reducing the clearance volume, reducing the ineffective space inside the cylinder, making the gas flow more concentrated and efficient. By reducing the sudden changes and unnecessary expansion areas in the flow path, the exhaust compression nut effectively reduces the local changes in the gas flow velocity. The exhaust base provides stable support to avoid flow interference caused by the movement or shaking of components. The exhaust base spring provides a constant and appropriate elastic force to ensure that the exhaust valve plate can close in a timely and complete manner. Prevent gas backflow, maintain the continuity and consistency of the gas, and avoid the turbulence that may occur when the gas suddenly interrupts and then restarts. The combined action of these components reduces the generation of turbulence and eddy currents.

[0018] 4. Reduce the impact load: The exhaust base and base spring added in this technical solution help to reduce the impact load on the exhaust valve plate and exhaust valve seat, reduce the resistance loss caused by the impact, and extend the service life of the air valve.

[0019] 5. Reduce the maintenance cost: In this technical solution, by reducing the resistance loss of the air valve and increasing the closing speed, the energy consumption can be reduced. Reduce the maintenance requirements for the air valve, thereby reducing the long-term operating cost. Description of the Drawings

Combining Figures 1 to 3 As shown, an exhaust valve assembly 5 of a compressor with a novel double protection structure according to the present utility model includes an exhaust valve seat 51, an exhaust valve plate 52, an exhaust spring 53, an exhaust base 54, a base spring 55 and an exhaust compression nut 56. The exhaust valve seat 51 is fixedly installed at the bottom of the exhaust valve position of the cylinder head 2 and can contact the piston end face. An exhaust valve plate 52 is placed on the middle through hole of the exhaust valve seat 51. The upper surface of the exhaust valve plate 52 abuts against the exhaust base 54 through the exhaust spring 53. The upper end of the exhaust base 54 abuts against the exhaust compression nut 56 through the base spring 55. The exhaust compression nut 56 is threadedly connected to the upper end of the cylinder head 2, and the screwing depth of the exhaust compression nut 56 can be adjusted by the thread to control the exhaust clearance volume.

[0027] There is a step portion 511 in the through hole of the exhaust valve seat 51, and the exhaust valve plate 52 is placed on the step portion 511. During intake, the exhaust valve plate 52 abuts against the step portion 511 under the elastic force of the exhaust spring 53 to close the exhaust valve.

[0028] The bottom of the exhaust base 54 is in communication, and there are a plurality of exhaust holes 541 on the side. Inside the exhaust base 54, there is a spring seat 542. The upper end of the exhaust spring 53 is fixedly connected to the outer periphery of the spring seat 542, and the lower end is connected to the exhaust valve plate 52. During exhaust, the piston assembly 3 pushes the gas in the cylinder to be discharged through the through hole of the exhaust valve seat 51. The exhaust valve plate 52 is pushed open, and the gas is discharged from the bottom of the exhaust base 54 to the exhaust holes 541, and finally discharged through the exhaust port 21 on one side of the cylinder head 2.

[0029] The upper end of the exhaust base 54 has a limit post 543. The exhaust compression nut 56 has a limit hole 561 inside. The limit post 543 of the exhaust base 54 is sleeved into the limit hole 561 of the exhaust compression nut 56 for limit fixation. A fixing seat for the base spring 55 is formed on the outer periphery of the limit hole 561. The upper end of the base spring 55 abuts against the bottom of the fixing seat, and the lower end abuts against the upper end of the exhaust base 54. A gap is formed between the base spring 55 and the exhaust compression nut 56.
