DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the accompanying drawings: See attached Figures 1 to 9 As shown: a double horizontal opposed air compressor with a heat dissipation structure, comprising: a motor 1 with openings at both ends; two air compression boxes 2, respectively connected to the openings at both ends of the motor 1, forming end covers 200 at both ends of the motor 1, each air compression box 2 is provided with piston compression assemblies 20 opposite to each other on the front and rear sides along the horizontal direction, the piston compression assembly 20 can inhale or compress gas and then exhaust, a drive shaft 100 is arranged in the motor 1, and both ends of the drive shaft 100 extend through the end cover 200 along its axial direction to the air compression box 2, and are connected to the piston compression assembly 20 at the corresponding end, fan blades 101 are arranged at both ends of the drive shaft 100, and the fan blades 101 at both ends face oppositely, and an air inlet and outlet 201 is arranged at one end of the two air compression boxes 2 away from the motor 1, and the fan blades 101 are located between the air inlet and outlet 201 and the piston compression assembly 20.

[0019] The air compressor includes a motor 1 with openings at both ends. The design of the motor 1 allows other components to be installed at both ends, thereby forming a complete power transmission system. In this embodiment, the openings at both ends of the motor 1 are designed to facilitate connection with the air compressor box 2, so as to facilitate assembly and maintenance. The two air compressor boxes 2 are respectively connected to the openings at both ends of the motor 1 to form end covers 200 at both ends of the motor 1. The front and rear sides of each air compressor box 2 are oppositely provided with piston compression assemblies 20 in the horizontal direction. The main function of the piston compression assembly 20 is to perform gas suction and compression operations, and then discharge the compressed gas. This design enables the air compressor to achieve efficient gas compression in a smaller space. A drive shaft 100 is provided in the motor 1. Both ends of the drive shaft 100 extend through the end cover 200 along its axial direction into the air compressor box 2 and are connected to the piston compression assembly 20 at the corresponding end. This means that the power generated by the motor 1 is transmitted to the piston compression assembly 20 through the drive shaft 100, thereby driving the compression assembly to complete the suction and exhaust actions. Fan blades 101 are provided at both ends of the drive shaft 100. The blades of the two fan blades 101 face opposite directions. This design ensures that when the motor 1 is started, the fan blades 101 can effectively guide the air flow, from one air compressor box to another. Air enters the air inlet and outlet 201 of the air compressor box 2, passes between the motor 1 and the piston compression assembly 20, and is discharged from the air inlet and outlet 201 of the other air compressor box 2. The fan blades 101 are located between the air inlet and outlet 201 and the piston compression assembly 20, which helps to form a closed air circulation path to ensure that the motor 1 and the compression assembly can be fully cooled. The two air compressor boxes 2 are provided with air inlets and outlets 201 at one end away from the motor 1 to ensure that air can enter and discharge smoothly. The position of the fan blades 101 is carefully designed to be placed between the air inlet and outlet 201 and the piston compression assembly 20 to facilitate guiding the air flow and achieve the best heat dissipation effect.

[0020] Specifically, Figures 2 to 5 As shown, an end cover 200 is integrally formed in the end of the air compressor box 2 close to the motor 1 , a bearing 202 is installed at the center of the end cover 200 , and the drive shaft 100 is installed in the bearing 202 .

[0021] An end cover 200 is integrally formed inside the end of the air compressor box 2 close to the motor 1. This design makes the end cover 200 directly become a part of the structure of the air compressor box 2, rather than a separate additional component. This not only simplifies the manufacturing process and reduces the number of parts, but also enhances the rigidity and stability of the overall structure. The end cover 200 is integrated inside the air compressor box 2, replacing the traditional independent end cover 200 design, thereby reducing the overall volume of the equipment, making the air compressor more compact, and easy to install and transport. A bearing 202 is installed at the center of the end cover 200. The main function of the bearing 202 is to support the drive shaft 100 and ensure that it can rotate smoothly. By installing the bearing 202 at the center of the end cover 200, it can be ensured that the drive shaft 100 maintains good concentricity during rotation, avoiding vibration and noise caused by deviation from the center. The design of the bearing 202 ensures that the rotation of the drive shaft 100 is smoother, reduces friction loss, and thus improves the transmission efficiency.

[0022] Furthermore, if Figure 4 and Figure 5 As shown, a limiting groove 203 is provided at the molding of the end cover 200 and the air compressor box 2 , and the motor 1 has a housing 102 , and the end of the housing 102 is inserted into the limiting groove 203 .

[0023] A limiting groove 203 is provided at the molding of the end cover 200 and the air compressor box 2. The limiting groove 203 surrounds the end cover 200. The design of the limiting groove 203 can not only play a positioning role, but also provide better support and guiding functions during the assembly process. The design of the limiting groove 203 makes the connection between the end cover 200 and the air compressor box 2 more stable, avoiding loosening due to external vibration or impact, thereby improving the structural stability of the entire device. The motor 1 has a shell 102, and the end of the shell 102 is inserted in the limiting groove 203, so that the connection between the motor 1 and the air compressor box 2 is more stable. The tightening also ensures that the motor 1 can be accurately positioned during the installation process. In addition, the close fit between the limit groove 203 and the end of the shell 102 simplifies the assembly process, making the installation of the motor 1 and the air compressor box 2 simpler and faster. The operator only needs to insert the end of the motor 1 shell 102 into the limit groove 203 to complete the installation. At the same time, it is convenient for disassembly during maintenance, reducing the disassembly and assembly time. The overall design makes the connection between the motor 1 and the air compressor box 2 more compact, reduces the overall volume of the equipment, improves the reliability and stability of the equipment, and reduces various faults caused by poor connection.

[0024] Furthermore, if Figure 4 and Figure 5 As shown, a plurality of heat sinks 103 are evenly arranged on the outer surface of the shell 102 along the axial direction of the drive shaft 100, the heat sink 103 is located in the limiting groove 203, and a plurality of first air guide holes 204 are opened on the bottom wall of the limiting groove 203, and the gaps between adjacent heat sinks 103 are connected to the first air guide holes 204.

[0025] A plurality of heat sinks 103 are evenly arranged on the outer surface of the housing 102 along the axial direction of the drive shaft 100. This evenly distributed design enables the heat sink 103 to evenly disperse heat when the motor 1 is working, thereby improving the heat dissipation efficiency. The heat sink 103 is located in the limiting groove 203. The design of the limiting groove 203 not only provides structural support, but also provides a stable environment for the installation of the heat sink 103, ensuring that the heat sink 103 will not be displaced or damaged due to external vibration. A plurality of first air guide holes 204 are opened on the bottom wall of the limiting groove 203. The design of these air guide holes makes The air can enter through the gaps between the heat sinks 103 and be discharged through the air guide holes, thereby forming an effective air flow channel. Through the design of the heat sink 103 and the first air guide holes 204, the air can enter along the gaps between the heat sinks 103 and be discharged through the first air guide holes 204, ensuring that the air can form an effective flow path around the heat sink 103, thereby taking away the heat generated by the motor 1. The design of the heat sink 103 and the first air guide holes 204 not only improves the heat dissipation efficiency, but also makes the overall structure more compact, reduces the size of the equipment, and facilitates installation and layout.

[0026] Furthermore, if Figure 4 and Figure 5 As shown, a plurality of first connection holes 104 are arranged on the outer wall of the housing 102 , and second connection holes 205 are correspondingly arranged on the limiting groove 203 , and the first connection holes 104 and the second connection holes 205 are connected by bolts.

[0027] A plurality of first connecting holes 104 are arranged on the outer wall of the shell 102, and a second connecting hole 205 is correspondingly arranged on the limiting groove 203. The first connecting holes 104 and the second connecting holes 205 are connected by bolts, which not only simplifies the assembly process, but also enhances the structural strength of the equipment so that the shell 102 and the air compressor box 2 are firmly connected together, thereby ensuring the stability of the equipment during operation.

[0028] Specifically, Figure 2 , Figure 3 , Figure 7 , Figure 8 and Fig. 9As shown, the piston compression assembly 20 includes: an eccentric wheel 206, a connecting rod arm 207, a piston rod 208, a piston cylinder body 209 and an air valve cover 210, the drive shaft 100 is installed in the eccentric wheel 206, one end of the connecting rod arm 207 is connected to the eccentric wheel 206, and the other end of the connecting rod arm 207 is connected to the piston rod 208, the air valve cover 210 and the piston cylinder body 209 are connected to one side of the air compressor box 2 by bolts, and the piston rod 208 is movably inserted in the piston cylinder body 209; when the piston rod 208 reciprocates in the piston cylinder body 209, the gas in the air valve cover 210 can be sucked into the piston cylinder body 209 or the compressed air can be exhausted from the air valve cover 210.

[0029] The piston compression assembly 20 includes an eccentric wheel 206, a connecting rod arm 207, a piston rod 208, a piston cylinder 209 and a valve cover 210. The drive shaft 100 is installed in the eccentric wheel 206. One end of the connecting rod arm 207 is connected to the eccentric wheel 206, and the other end of the connecting rod arm 207 is connected to the piston rod 208. The valve cover 210 and the piston cylinder 209 are connected to one side of the air compression box 2 by bolts, and the piston rod 208 is movably inserted in the piston cylinder 209. When the piston rod 208 reciprocates in the piston cylinder 209, the gas in the valve cover 210 can be sucked into the piston cylinder 209 or the compressed air can be exhausted from the valve cover 210, which can achieve efficient gas compression and discharge.

[0030] It is worth mentioning that Figure 8 As shown, the bearings 202 are directly provided on the eccentric wheel 206 and the connecting rod arm 207, so that when the driving shaft 100 drives the eccentric wheel 206 to rotate, the piston rod 208 improves the transmission efficiency and can reciprocate in the piston cylinder 209 more quickly and stably.

[0031] Specifically, Figure 2 , Figure 3 , Figure 7 , Figure 8 and Fig. 9 As shown, an assembly part 211 is provided on both sides of the air compressor box 2, a through hole 212 is opened at the center position of the assembly part 211, the air valve cover 210 and the piston cylinder body 209 are connected to the outer side of the assembly part 211 by bolts, and the size of the through hole 212 is the same as the cylinder mouth size of the piston cylinder body 209, and a plurality of second air guide holes 213 surrounding the through hole 212 are opened on the assembly part 211, and the second air guide holes 213 are connected to the air inlet and outlet 201.

[0032] An assembly part 211 is provided on both sides of the air compressor box 2, and a through hole 212 is opened at the center position of the assembly part 211. The air valve cover 210 and the piston cylinder body 209 are connected to the outside of the assembly part 211 by bolts, and the size of the through hole 212 is the same as the cylinder mouth size of the piston cylinder body 209. A plurality of second air guide holes 213 surrounding the through hole 212 are opened on the assembly part 211, and the second air guide holes 213 are connected to the air inlet and outlet 201. This design enables the two horizontally opposed piston compression assemblies 20 to move stably, ensures that the air can pass through each air guide hole smoothly, and improves the heat dissipation effect.

[0033] Assembly parts 211 are provided on both sides of the air compressor box 2. The assembly parts 211 are used to fix and support the piston compression assembly 20. A through hole 212 is opened at the center of the assembly part 211. The size of the through hole 212 is the same as the cylinder mouth size of the piston cylinder body 209. This design enables the piston cylinder body 209 to be accurately docked with the air compressor box 2, and the air valve cover 210 and the piston cylinder body 209 are connected to the outer side of the assembly part 211 by bolts, ensuring the stable installation of the piston compression assembly 20. Specifically, the design of the assembly portion 211 not only provides precise positioning for the piston cylinder 209, but also ensures the tight fixation of the air valve cover 210 and the piston cylinder 209 by bolt connection, so as to ensure the stability and sealing of the piston compression assembly 20 during operation. In addition, the assembly portion 211 is provided with a plurality of second air guide holes 213 arranged around the through hole 212, and these air guide holes are connected to the air inlet and outlet 201. This design enables the cooling air to pass through each air guide hole smoothly, thereby improving the heat dissipation effect. For this reason, in the horizontally opposed air compressor mentioned in this embodiment, it is specifically manifested as follows: the design of the assembly portion 211 ensures The stable installation of the piston compression assembly 20 enables the two horizontally opposed piston compression assemblies 20 to maintain a stable state of motion during operation, reducing vibration and noise caused by unstable motion. The design of the second air guide holes 213 enables air to pass through these holes smoothly, which not only optimizes the air flow path, but also ensures the fluidity of the air before entering the piston cylinder 209 and after being discharged, reduces air flow resistance, and improves compression efficiency. Through the connection between the second air guide holes 213 and the air inlet and outlet 201, cooling air can circulate effectively, taking away the heat generated by the piston compression assembly 20 during operation, thereby improving the heat dissipation efficiency and extending the service life of the equipment.

[0034] Furthermore, if Figure 3 and Figure 8 As shown, a heat dissipation fin 214 is disposed on the outer side of the air valve cover 210 , and a third air guide hole 215 is opened on the air valve cover 210 . The third air guide hole 215 surrounds the heat dissipation fin 214 and is communicated with the through hole 212 .

[0035] The outer surface of the air valve cover 210 is provided with heat dissipation fins 214, and the air valve cover 210 is provided with a third air guide hole 215. The third air guide hole 215 surrounds the heat dissipation fins 214 and is connected with the through hole 212. The heat dissipation fins 214 are provided to help the piston rod 208 to squeeze the piston cylinder 209 to compress the air. Through the combined design of the heat dissipation fins 214 and the third air guide holes 215, the heat generated by the piston rod 208 when compressing the air can be dissipated more quickly, avoiding excessive temperature caused by heat accumulation, thereby protecting the piston compression assembly 20 and other key components. The generated heat energy can be quickly discharged through the heat dissipation fins 214, thereby increasing the heat dissipation area of ​​the air valve cover 210 and further improving the heat dissipation effect.

[0036] Furthermore, if Figures 6 to 8 As shown, the air valve cover 210 is connected to the piston cylinder body 209 to form a chamber, one end of the air valve cover 210 is provided with an air inlet valve pipe 216, and the other end of the air valve cover 210 is provided with an air outlet valve pipe 217.

The air inlet chamber 219 is connected with the piston chamber 220 through the air inlet hole 222, and the piston chamber 220 is connected with the air outlet chamber 221 through the air outlet hole 223, thereby ensuring the orderly flow of gas and improving the compression efficiency. It is worth mentioning that an air inlet valve is provided on the air inlet valve pipe 216, and an air outlet valve is provided on the air outlet valve pipe 217.

[0038] The specific working principle of the piston compression assembly 20 in the present invention is as follows: when the driving shaft 100 of the motor 1 drives the eccentric wheel 206 to make an eccentric movement to move the piston rod 208 outward through the connecting arm 207, a negative pressure is formed inside the piston chamber 220, and the external air enters the air inlet chamber 219 through the air inlet valve, and enters the piston chamber 220 through the air inlet hole 222 at the bottom of the piston cylinder 209. When the piston rod 208 moves inward, the air in the piston chamber 220 is compressed and the pressure increases. The compressed air enters the air outlet chamber 221 through the air outlet hole 223 at the bottom of the piston cylinder 209. When the pressure of the compressed air exceeds a certain threshold, the air outlet valve opens, and the compressed air is discharged to the external device or the air storage tank through the air outlet valve.
