AI Technical Summary
Existing high-efficiency diaphragm compressors have shortcomings in air compression efficiency, resulting in some kinetic energy not being effectively utilized.
A high-efficiency diaphragm compressor was designed. By setting a one-way ventilation structure in the air inlet and outlet frames, the diaphragm can compress air in any direction during reciprocating motion. With the cooperation of the sealing plate and spring, air can be ensured to enter or exit under high pressure or negative pressure respectively, thus achieving all-round air compression.
This greatly improves air compression efficiency, ensuring that the diaphragm can compress air immediately during reciprocating motion, preventing air leakage and improving the utilization rate of kinetic energy.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of compressor technology, and more specifically, to a high-efficiency diaphragm compressor. Background Technology
[0002] Diaphragm compressors are primarily used for compressing and transporting gases. They feature high sealing and zero pollution, making them suitable for applications requiring high-purity, rare, valuable, corrosive, or radioactive gases. Their working principle involves the reciprocating motion of a diaphragm within a cylinder to compress and transport the gas. The diaphragm is mechanically or hydraulically driven within the cylinder. Diaphragm compressors are not contaminated during compression and operate without leakage, making them particularly suitable for compressing high-purity, rare, valuable, corrosive, radioactive, toxic, or explosive gases.
[0003] Chinese Patent No. CN218717369U discloses a high-efficiency noise-reducing air compressor, including a connecting plate. Support bases are attached to both sides of the top of the connecting plate. Mounting structures are fitted onto the exterior of both the support bases and the connecting plate. An air compressor body is fixedly connected to the middle position of the top of the support bases. An intake pipe is fixedly connected to one side of the air compressor body, and an outlet pipe is fixedly connected to the other side. Noise-reducing structures are fitted onto the exterior of both the intake and outlet pipes. This high-efficiency noise-reducing air compressor, through the cooperation of a soft layer and a buffer plate, can wrap the intake and outlet pipes during air intake and exhaust, reducing noise generation. The cooperation of the mounting pipe and connecting spring can isolate and buffer noise. The connecting spring and its internal damper can reduce vibration caused by noise, increasing stability during use.
[0004] Currently, while existing high-efficiency diaphragm compressors can provide excellent noise reduction and sound insulation, their air compression efficiency is relatively low, resulting in a small portion of the compressor's kinetic energy not being utilized. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a high-efficiency diaphragm compressor, which aims to improve the problem of low air compression efficiency of diaphragm compressors under normal circumstances.
[0006] This utility model is implemented as follows:

[0023] Please see Figure 1-4This utility model provides a technical solution: a high-efficiency diaphragm compressor, including a drive structure 100 and a ventilation structure 200 fixed to one side of the drive structure 100. The drive structure 100 includes a base frame 110 and a suction component 120, with the suction component 120 fixed to the top of the base frame 110. The ventilation structure 200 includes an outlet component 210 and an inlet component 220, with the outlet component 210 fixed to one side of the suction component 120. The inlet component 220 includes an inlet frame 221, which is fixed to both a support platform 121 and a pressure frame 123, and is also fixed to one side of the suction component 120. An air intake ring 222 is fixed inside the air intake frame 221. A guide rod 223 is slidably connected inside the air intake ring 222. The guide rod 223 restricts the sealing plate 225 and supports the spring 226. A limit piece 224 is fixed at the end of the guide rod 223. The limit piece 224 provides a force point for the spring 226. A sealing plate 225 is slidably connected to one side of the guide rod 223. After the sealing plate 225 is in contact with the air intake ring 222, it can prevent air from being discharged from the equipment. A spring 226 is sleeved on one side of the guide rod 223. An air intake pipe 227 is fixed on one side of the air intake frame 221.
[0024] Please see Figure 1-2 An oil pipe 111 is fixed to one side of the base frame 110. A drive shaft 112 is rotatably connected inside the base frame 110. The drive shaft 112 is connected to an external motor or engine. A rocker plate 113 is fixed to the end of the drive shaft 112. A connecting rod 114 is rotatably connected to one side of the rocker plate 113. The connecting rod 114 is not on the same axis as the drive shaft 112. A connecting bracket 115 is rotatably connected to one side of the connecting rod 114. The suction component 120 includes a support platform 121, which is fixed to the top of the base frame 110. A diaphragm 122 is provided on the top of the support platform 121. The diaphragm 122 is clamped and fixed to the support platform 121 by a pressure frame 123 and an O-ring. The pressure frame 123 is provided on the top of the support platform 121 and is fixed to the top of the support platform 121 by bolts. A connecting plate 124 is fixed to one side of the diaphragm 122. A piston 125 is fixed to the end of the connecting plate 124. Multiple sealing rings are sleeved on one side of the piston 125. A rotating rod 126 is rotatably connected inside the piston 125. The rotating rod 126 is rotatably connected to the connecting frame 115.
[0025] Please see Figure 1-3 and Figure 4The air outlet component 210 includes an air outlet frame 211, which is fixed to one side of the support platform 121. An air outlet hole 212 is provided inside the air outlet frame 211. A guide rod 213 is fixed inside the air outlet frame 211. The guide rod 213 restricts the movement of the sealing plate 215 and supports the spring 216. A limit piece 214 is fixed at the end of the guide rod 213. The sealing plate 215 is slidably connected to one side of the guide rod 213. After the sealing plate 215 blocks the air outlet hole 212, it can prevent external air from entering the equipment. A spring 216 is sleeved on one side of the guide rod 213. An air outlet pipe 217 is fixed on one side of the air outlet frame 211.
[0026] Specifically, the working principle of this high-efficiency diaphragm compressor is as follows: During operation, the drive shaft 112 drives the rocker vane 113 to rotate, which in turn causes the connecting frame 115 to drive the piston 125 to reciprocate under the constraint of the support platform 121. This, in turn, causes the connecting plate 124 to drive the diaphragm 122 to reciprocate. Assuming that when the diaphragm 122 moves downward, the lower part of the diaphragm 122 will be compressed to form high pressure, while the upper part will form negative pressure. When the negative pressure is lower than the external air pressure, the external air will push the sealing plate 225 and compress the spring 226, thereby allowing air to enter the space between the pressure frame 123 and the diaphragm 122 through the intake ring 222. During charging, the negative pressure causes the sealing plate 215 above the air outlet frame 211 to be tightly pressed against the air outlet 212 under the conditions of the spring 216 and the external high pressure, thereby preventing air from being discharged. At the same time, when the high pressure is higher than the external air pressure, the high pressure will push the sealing plate 215, and the high-pressure air will be discharged into the air outlet pipe 217 through the air outlet 212, thereby completing the depressurization state. During the depressurization state, the sealing plate 225 below the air inlet frame 221 will be tightly pressed against the air inlet ring 222 under the conditions of the spring 226 and the high pressure, thereby preventing air leakage. Therefore, in this way, the diaphragm 122 can immediately compress air during reciprocating motion.
[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
