[0042] In the above structure, the air is filtered by the front middle filter element 313, and then the air enters between the rear compression block 343 and the middle baffle 302 through the front middle air inlet check valve 312. When the air between the rear compression block 343 and the middle baffle 302 is compressed, the air is discharged through the front middle air outlet check valve 314. The rear middle filter element 318 filters the air, and then the air enters between the front compression block 344 and the middle baffle 302 through the rear middle air inlet check valve 317.

[0045] In a preferred embodiment: the inner wall of the rear air intake channel 322 is fixedly equipped with a rear air intake one-way valve 324, the top of the rear air intake one-way valve 324 is fixedly equipped with a rear filter element 325, the inner wall of the rear air outlet channel 323 is fixedly equipped with a rear air outlet one-way valve 326, the top of the rear air outlet one-way valve 326 is fixedly equipped with a rear connecting pipe 327, and the rear connecting pipe 327 is connected to the air storage tank 328.

[0046] In the above structure, the air is filtered by the rear filter element 325, and then the air enters between the front compression block 344 and the rear baffle 303 through the rear air inlet one-way valve 324. When the air between the front compression block 344 and the rear baffle 303 is compressed, the air will enter the rear connecting pipe 327 through the rear air outlet one-way valve 326, and then enter the air storage tank 328 through the rear connecting pipe 327 for storage.

[0047] In a preferred embodiment: the outer edge of the rotating shaft 346 is fixedly sleeved with a swinging piece 347, the outer edge of the swinging piece 347 is fixedly equipped with a cylinder 348, the outer edge of the cylinder 348 is movably sleeved with a connecting rod 349, the end of the connecting rod 349 away from the cylinder 348 is movably sleeved with a connecting column 350, the outer edge of the connecting column 350 is fixedly equipped with a steel sheet 351, and the inner wall of the steel sheet 351 is fixedly sleeved on the power output shaft of the drive motor 352.

[0048] In the above structure, the steel sheet 351 and the connecting column 350 are driven to rotate by the driving motor 352. When the connecting column 350 rotates, it pushes and pulls the connecting rod 349. When the connecting rod 349 is pushed and pulled, it pushes and pulls the swinging piece 347. Therefore, the swinging piece 347 can be swung. The swinging of the swinging piece 347 drives the connecting bracket 345 and the arc bracket 342 on the rotating shaft 346 to swing, so that the air between the front baffle 301 and the middle baffle 302, and the middle baffle 302 and the rear baffle 303 can be compressed.

[0050] In the above structure, the front slider 338 and the front baffle 301, the middle slider 339 and the middle baffle 302, and the rear slider 340 and the rear baffle 303 are fixed respectively by multiple fixing bolts 341, so that the front slider 338, the middle slider 339 and the rear slider 340 can fix the front sealing ring 332, the middle sealing ring 333 and the rear sealing ring 334, so that the front sealing ring 332, the middle sealing ring 333 and the rear sealing ring 334 will not shake, thereby improving the stability of the device.

The right sealing gasket 23 and the left sealing gasket 24 can prevent the air in the outer shell 2 from being discharged from the gap between the right sealing plate 21 and the outer shell 2 and the left sealing plate 22 and the outer shell 2 when compressed, and also prevent external gas from entering through the gap between the outer shell 2 and the right sealing plate 21 and the gap between the outer shell 2 and the left sealing plate 22.

[0053] Working principle: when in use, the steel sheet 351 and the connecting column 350 are rotated by the driving motor 352. When the connecting column 350 rotates, it pushes and pulls the connecting rod 349. When the connecting rod 349 is pushed and pulled, it pushes and pulls the swinging piece 347. Therefore, the swinging piece 347 can be swung. The swinging of the swinging piece 347 drives the connecting bracket 345 and the arc bracket 342 on the rotating shaft 346 to swing. When the arc bracket 342 swings, it drives the rear compression block 343 and the front compression block 344 to swing. When the rear compression block 343 moves toward the middle baffle 302, the rear compression block Pressure is generated between 343 and the middle baffle 302, and suction is generated between the rear compression block 343 and the front baffle 301. At this time, the air between the middle baffle 302 and the rear compression block 343 is compressed. At this time, the compressed air enters the air storage tank 328 through the front middle air outlet channel 311, the front middle air outlet one-way valve 314, the connecting pipe 320 and the middle air inlet pipe 321. At the same time, the outside air enters between the rear compression block 343 and the front baffle 301 through the front filter element 307, the front air inlet one-way valve 306 and the front air inlet channel 304. At the same time, the air between the front compression block 344 and the rear baffle 303 is also compressed. The air flows through the rear air outlet channel 323, the rear air outlet one-way valve 326 and the rear connecting pipe 327 into the air storage tank 328. At this time, the air between the front compression block 344 and the middle baffle 302 passes through the rear middle filter element 318, the rear middle air inlet one-way valve 317 and the rear middle air inlet channel 315 and enters between the front compression block 344 and the middle baffle 302. When the front compression block 344 and the rear compression block 343 move toward the front baffle 301, the front compression block 344 and the rear compression block 343 respectively draw the outside air through the rear filter element 325, the rear air inlet one-way valve 324 and the rear air inlet channel 322 into the front compression block 344 and the middle baffle 302. Between the rear baffle 303, the air passes through the front middle filter element 313, the front middle air inlet one-way valve 312 and the front middle air inlet channel 310 and enters between the middle baffle 302 and the rear compression block 343. At the same time, the air between the front compression block 344 and the middle baffle 302 is compressed. At this time, the compressed air enters the air storage tank 328 through the rear middle air outlet channel 316, the rear middle air outlet one-way valve 319, the connecting pipe 320 and the middle air inlet pipe 321. The compressed air between the rear compression block 343 and the front baffle 301 is compressed into the air storage tank 328 through the front air outlet channel 305, the front air outlet one-way valve 308 and the front connecting pipe 309.
