[0019] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of an air compressor exhaust guide structure and an air compressor of the present invention in conjunction with the accompanying drawings.
[0020] like Figure 1-3As shown, an air compressor includes a cylinder body 1, a cylinder head 2, a piston assembly 3 and a crankshaft 4. The cylinder head 2 is arranged at the upper end of the cylinder body 1. The cylinder head 2 and the cylinder body 1 form an intake cavity 11 and an exhaust cavity 12. The piston assembly 3 and the crankshaft 4 are arranged in the cylinder body 1. The piston assembly 3 is fixedly connected to the crankshaft and is driven by the crankshaft 4 to move up and down in the intake cavity 11 and the exhaust cavity 12 respectively to achieve intake and exhaust. The cylinder head 2 includes an upper cylinder head 21 and a lower cylinder head 23. The upper cylinder head 21 and the lower cylinder head 23 are tightly fixedly connected to form an intake and exhaust structure and a cooling structure therebetween for exhausting the intake air and liquid cooling the gas. The upper cylinder head 21 has an intake hole 211 and an exhaust hole 212. The gas enters through the intake hole 211 and is discharged through the exhaust hole 212. The lower cylinder head 23 has cooling holes 231 on both sides. Coolant enters through one cooling hole 231 and exits through the other. To facilitate installation of the coolant interface, more than two cooling holes 231 can be provided. During use, unconnected cooling holes 231 can be sealed with plugs. During docking, the interface of the cooling hole 231 can be flexibly selected according to the required location.
[0021] The utility model adds a middle cylinder head 22 between the upper cylinder head 21 and the lower cylinder head 23. The upper, middle, and lower cylinder heads 21, 22, 23 are tightly connected from top to bottom. The upper, middle, and lower cylinder heads 21, 22, 23 each form a uniform exhaust cavity 221, an intake cavity 222, a cooling channel 223, and a pressure relief cavity 224. The intake hole 211 connects to the exhaust cavity 221, the exhaust hole 212 connects to the intake cavity 222, and the cooling channel hole 231 connects to the cooling channel 223. The middle cylinder head 22 is made of YL104 and improves the structural strength of the air compressor. The middle cylinder head 22 effectively reinforces the entire compressor structure, improving its resistance to pressure and vibration, and increasing its stability and durability. It also acts as a seal to prevent air and lubricating oil leakage, ensuring the normal operation and efficiency of the air compressor.
[0022] A guide plate 24 is provided between the exhaust chambers 221 of the upper cylinder head 21 and the middle cylinder head 22 and between the exhaust chambers 221 of the middle cylinder head 22 and the lower cylinder head 23. The guide plate 24 is fixed to the lower surface of the upper cylinder head 21 and the lower surface of the middle cylinder head 22 by fasteners 241 respectively. The guide plate 24 is used to form a guide structure. The material of the guide plate 24 is Q235. Under the action of air pressure, the guide plate 24 floats in the exhaust cavity 221 to form the following guide functions: 1. The guide plate 24 can effectively guide the air flow, effectively reduce the vortex and turbulence of the air in the cylinder head, improve the air flow efficiency, and thus improve the compression efficiency; 2. Reduce the noise and vibration generated by the vortex and turbulence, and reduce the working noise and vibration level of the air compressor; 3. Increase the structural strength of the cylinder head to a certain extent, increase the pressure and temperature bearing capacity of the cylinder head, and improve the overall stability and reliability of the air compressor; 4. By optimizing the air flow, reduce energy loss, improve energy utilization efficiency, reduce the energy efficiency of the air compressor, and reduce operating costs.
[0023] The front side of the lower cylinder cover 23 also has a pressure relief hole 232, which is connected to the pressure relief chamber 224 and is used to adjust the pressure in the pressure relief chamber 224. In the present invention, the upper surface of the lower cylinder cover 23 is also covered with a pressure relief valve plate 25, which is used to form a diversion guide structure with a function and effect similar to that of the guide plate 24.
