Description

Technical Field

[0001] The present invention relates to the technical field of gas compression machinery manufacturing, and more specifically, to an energy-saving air compressor. Background Art

[0002] The advantages of piston air compressors are simple structure, long service life, and easy to achieve large capacity and high pressure output. The disadvantages are large vibration and noise, and because the exhaust is intermittent, the output is pulsed, and an air storage tank is required. When the piston in the cylinder moves to the right, the pressure in the left chamber of the piston in the cylinder is lower than the atmospheric pressure, the suction valve opens, and the outside air is sucked into the cylinder. This process is called the compression process. When the pressure in the cylinder is higher than the pressure in the output air pipeline, the exhaust valve opens. The compressed air is sent to the air pipeline. This process is called the exhaust process. The reciprocating motion of the piston is formed by the crank slider mechanism driven by the motor.

[0003] The Chinese patent with application number CN202210848238.4 discloses a new type of air compressor, including a cylinder body, in which a piston that moves up and down is arranged inside; an air inlet, which includes an upper air inlet and a lower air inlet, the two air inlets are connected to the upper and lower ends of the cylinder body respectively, and the two air inlets are alternately turned on and off; an air outlet, which includes an upper air outlet and a lower air outlet, the two air outlets are connected to the upper and lower ends of the cylinder body respectively, and the two air outlets are alternately turned on and off; the upper air inlet and the lower air outlet, and the lower air inlet and the upper air outlet are synchronously turned on or off respectively. In the new type of air compressor exemplified by the present invention, the piston is working in the reciprocating process, and the theoretical value is twice that of the existing piston air compressor, achieving the purpose of energy saving and emission reduction. However, the patent does not solve the problem that the piston reciprocates for a long time, resulting in excessive wear of the machine parts, which reduces the efficiency of the machine, generates noise and vibration when the air compressor is working, the severe wear of the piston cylinder leads to a large related gap, the air leakage volume increases sharply and affects the exhaust volume, and the leakage of compressed air will cause huge energy loss.

[0004] At present, when an air compressor is actually used, its piston that reciprocates up and down is in contact with the inner wall of the cylinder body for a long time, and combined with the impact of the gas entering the cylinder body on the piston, the outer wall of the piston can be deformed and damaged. The serious wear of the piston and cylinder leads to a large related gap, and the air leakage volume increases sharply, affecting the exhaust volume, and then causing air leakage between the piston and the cylinder body, which is not convenient for actual use.

[0029] Example 1

[0030] Existing air compressors, during operation, long-term use will also cause excessive wear of machine parts, resulting in reduced efficiency of the machine.

A filter sleeve for filtering dust and impurities is provided, and sealing gaskets are fixedly connected at the connection points between the air inlet pipe 34, the air outlet pipe 35 and the top cover 33 to enhance their air tightness, so that the components of the device are tightly connected without leakage during operation, which is more convenient for practical use. A transmission shaft 37 is rotatably connected to the interior of the crankcase 31, a crank 38 is fixedly connected to the outer wall of the transmission shaft 37, a connecting rod 39 is rotatably connected to one side of the crank 38, and a piston assembly 310 is slidably connected to the inner cavity of the cylinder body 32. When used under normal conditions, the transmission shaft 37 drives the crank 38 to rotate, so that the connecting rod 39 can drive the piston assembly 310 to move up and down in the inner cavity of the cylinder body 32.

[0033] like Figure 2-4As shown, the driving mechanism 4 includes a controller 41 fixedly connected to one side of the lifting frame 2, a limit frame 42 electrically connected to the controller 41 is fixedly connected to the bottom of the lifting frame 2, a lithium battery 43 is fixedly connected inside the limit frame 42, one end of the lithium battery 43 is electrically connected to a dual-axis motor 44, and the output end of the dual-axis motor 44 is fixedly connected to a transmission gear 45, wherein the lithium battery 43 is used to supply power to the controller 41 and the dual-axis motor 44, and the controller 41 is used to drive and adjust the opening and closing and the speed of the dual-axis motor 44, so that the air supply time of the device can be adjusted at any time, and the user can adjust it according to the actual use requirements during actual use. , which is more conducive to improving the working efficiency of the device, and when the device is actually used, the lithium battery 43 can replace the traditional AC plug-in, making the device easy to take and can also meet the power requirements of users when used at home, which is more convenient for actual use. The lithium battery 43 is connected to the inside of the limit frame 42 in a plug-in state, and a circuit protection component is provided on the inner wall of the limit frame 42 to protect the lithium battery 43 to avoid overcurrent, low voltage or short circuit problems of the lithium battery 43 when in use, thereby avoiding the occurrence of fire accidents caused by the explosion of the lithium battery 43, and users can use it more safely and at the same time, referring to Figure 5 As shown, one end of the transmission shaft 37 extending out of the outer wall of the crankcase 31 is fixedly connected to a gear plate 46 , and a synchronous belt 47 is meshed with the outer wall of the gear plate 46 and the transmission gear 45 .

[0034] Start the controller 41 to rotate the dual-axis motor 44, which drives the transmission gear 45 to rotate. The transmission gear 45 rotates and drives the gear plate 46 to rotate through the synchronous belt 47. The gear plate 46 drives the transmission shaft 37 to rotate. The transmission shaft 37 drives the crank 38 to rotate. The crank 38 drives the connecting rod 39 to rotate. The connecting rod 39 is displaced to drive the piston assembly 310 to move up and down as a whole in the inner cavity of the cylinder body 32. When the piston assembly 310 moves downward, a suction force is generated. The gas enters the interior of the intake pipe 34 through the filter sleeve with the suction force. The gas inside the intake pipe 34 enters the interior of the cylinder body 32 through the one-way valve. When the gas inside the cylinder body 32 is full, the piston assembly 310 moves upward. The piston assembly 310 pushes the gas inside the cylinder body 32 through the one-way valve into the interior of the outlet pipe 35, and the gas enters the interior of the gas storage tank body 1 through the outlet pipe 35.

[0035] like Figure 5 , 6As shown, in order to ensure the sealing of the piston assembly 310 when it moves up and down, the piston assembly 310 includes a limit plate 3010, the connecting rod 39 is hinged to the limit plate 3010, the outer wall of the limit plate 3010 is in sealing contact with the inner wall of the cylinder body 32, a plurality of limit slots 311 are provided inside the limit plate 3010, a plurality of first slides 312 are slidably connected inside the limit plate 3010, and the tops of the plurality of first slides 312 are fixedly connected to the limit slots 311. The sliding rod 315 is slidably connected, and the internal sliding connection of the limiting plate 3010 is connected to the second sliding plate 313 arranged on the outside of the first sliding plate 312. The second sliding plate 313 is fixedly connected to a sealing block 314 on the side close to the outer wall of the limiting plate 3010. The sealing block 314 is arranged in an arc shape. The first sliding plate 312, the second sliding plate 313 and the sealing block 314 are arranged in a one-to-one correspondence. The circumferential curvature of the sealing block 314 is consistent with the circumferential curvature of the limiting plate 3010.

[0036] The sealing block 314 can change the contact range between the sealing block 314 and the cylinder body 32 according to its damaged state due to long-term use by adjusting the extension length of the second slide 313, thereby extending the service life of the piston assembly 310 and making the sealing effect of the sealing block 314 better, avoiding the piston assembly 310 from being deformed and damaged by long-term air pressure shock and then causing air leakage, reducing the wear of the air compressor machine parts, thereby improving the working efficiency of the air compressor, ensuring the safety and health of workers, reducing costs, being environmentally friendly and energy-saving, and extending the service life of the air compressor.

[0037] By cooperating with the second slide 313 and the sealing block 314, the contact range between the sealing block 314 and the cylinder body 32 is changed, thereby extending the service life of the piston assembly 310, avoiding the piston assembly 310 from being deformed and damaged by long-term air pressure shock and then causing air leakage, reducing the wear of the air compressor machine parts, thereby improving the working efficiency of the air compressor, ensuring the safety and health of workers, reducing costs, being environmentally friendly and energy-saving, and extending the service life of the air compressor.

[0038] Example 2

[0039] In the existing air compressor, during operation, the piston reciprocates for a long time, noise and vibration are generated during operation, severe wear of the piston and cylinder leads to large related gaps, a sharp increase in air leakage affects the exhaust volume, and compressed air leakage causes huge energy loss. Based on the above embodiments.

[0040] like Figure 3-7As shown, the top of the limit plate 3010 is rotatably connected to a turntable 316, and the top of the turntable 316 is provided with a plurality of positioning slots 317 slidably connected to the slide rod 315, and the plurality of positioning slots 317 are all arranged in a ring-shaped manner around the circumferential surface of the turntable 316 in an equidistant state in sequence, and the plurality of limit slots 311, the first slide 312, the second slide 313 and the sealing block 314 are all arranged in a ring-shaped manner around the circumferential surface of the limit plate 3010 in an equidistant state in sequence, and the circumferential radius length of the turntable 316 is greater than the straight length of the limit slot 311 Under normal conditions, the turntable 316 performs a limiting and shielding treatment on the top of the limiting plate 3010 to prevent the first slide 312 from leaking when sliding. The first slide 312 is fixedly connected to a first magnetic block 321 on one side close to the second slide 313, and the second slide 313 is fixedly connected to a second magnetic block 322 on one side close to the first slide 312. The first magnetic block 321 and the second magnetic block 322 are arranged in a magnetically repulsive state, and a telescopic spring 323 is fixedly connected between the first magnetic block 321 and the second magnetic block 322.

[0041] like Figure 4 , 5 As shown, a columnar groove is opened at the vertical center line position of the limit plate 3010, and the inner cavity of the columnar groove is connected to a threaded screw 318 in an up and down sliding state. The threaded screw 318 passes through the top of the turntable 316 and is fixedly connected to a pressure plate 319. The threaded screw 318 and the turntable 316 are arranged in a mutually meshing state. The top of the limit plate 3010 is fixedly connected to a positioning rod 320 arranged in a vertical state, and the pressure plate 319 is slidably connected to the outer wall of the positioning rod 320.

[0042] When the limit plate 3010 is pushed up and down, the pressure plate 319 is squeezed by the gas between the cylinder body 32 and the intake pipe 34, so that the pressure plate 319 is forced to drive the threaded screw 318 to move downward into the inside of the columnar groove. At the same time, the turntable 316 engaged with the threaded screw 318 is forced to rotate. The rotation of the turntable 316 can cause the positioning slide groove 317 to move. The positioning slide groove 317 limits the slide rod 315 and drives the first slide 312 to slide inside the limit plate 3010, thereby driving multiple first slides 312 to move. When moving, the first slide 312 drives the first magnetic block 321 to move. Due to the repulsive force between the first magnetic block 321 and the second magnetic block 322, the first magnetic block 321 drives the second magnetic block 322 to move. The second magnetic block 322 pushes the second slide 313 and the sealing block 314 to move toward the outer wall of the limiting plate 3010, so that the gap between the limiting plate 3010 and the inner wall of the cylinder body 32 is reduced, and the overall sealing of the limiting plate 3010 is improved, so that the sealing between the cylinder body 32 and the limiting plate 3010 is stronger, and the gap between the cylinder body 32 and the limiting plate 3010 is reduced. The uneven force on the piston assembly 310 is reduced to avoid vibration during operation. The rotating disk 316 performs a limit shielding treatment on the top of the limit plate 3010. During operation of the air compressor, the sealing block 314 is always forced to move toward the outer wall of the limit plate 3010 to limit the position. The gas can be better circulated between the limit plate 3010 and the intake pipe 34 for use. The air compressor can adjust the seal according to the use status, avoiding the energy waste caused by the leakage during the sliding process of the first slide 312 due to the setting of the limit slide groove 311 being too long, so that the seal of the air compressor is The effect is stronger. The positioning rod 320 limits the overall position of the pressure plate 319 to prevent it from rotating when moving up and down, which in turn affects the problem that the turntable 316 cannot rotate, and avoids the leakage of compressed air that will cause huge energy losses, thereby improving the energy-saving effect of the air compressor and the working efficiency of the air compressor. The multiple second slides 313 and sealing blocks 314 that can be adjusted for horizontal displacement can change and adjust the impact positions of the multiple sealing blocks 314 and the gas, thereby preventing the piston assembly 310 from being deformed and damaged by the impact of gas for a long time, and then causing leakage.

[0043] During the up and down movement of the limit plate 3010, the pressure plate 319 is forced to move downward and drive the turntable 316 to rotate. The first magnetic block 321 and the second magnetic block 322 cooperate with each other. The second magnetic block 322 pushes the second slide 313 and the sealing block 314 to move toward the outer wall of the limit plate 3010. The gap between the cylinder body 32 and the limit plate 3010 is reduced, and the uneven force on the piston assembly 310 is reduced, avoiding vibration during operation and avoiding huge energy loss caused by compressed air leakage, thereby improving the energy-saving effect of the air compressor and the working efficiency of the air compressor.
