[0026] Turbine 22 is placed in shell 21, one of the output shafts of double-shaft motor 11 penetrates into shell 21, one of the output shafts of double-shaft motor 11 is fixedly connected with the center of turbine 22, fixing part 23 is fixedly connected with one of the output shafts of double-shaft motor 11, fixing part 23 top touches turbine 22, and fixing part 23 limits turbine 22 on the output shaft of double-shaft motor 11;Double-shaft motor 11 drives turbine 22 to rotate and extracts air from the outside of shell 21, air enters shell 21 from first air inlet 212, and turbine 22 pushes to first air outlet 213 after the first compression of air

[0027] Further, a plurality of first blades 221 are extended on turbine 22, a plurality of second blades 222 are extended on turbine 22, the second blades 222 are located between two adjacent first blades 221, and the area of the first blades 221 is greater than the area of the second blades 222;Because the area of the first blades 221 is relatively large, the cavity formed is relatively large, the first blades 221 are more easily to suck low-pressure thin air of first air inlet 212, and the working efficiency of fan 2 is improved;The area of the second blades 222 is relatively small, and the cavity formed is also small, and the second blades 222 are more easily to push compressed air out of first air outlet 213

[0028] Furthermore, the first air inlet 212 is located near the center of the turbine 22, and the first air outlet 213 is located near the outer side of the turbine 22.

[0029] The bracket 1 has a connecting pipe 12 on its outer side, and one end of the connecting pipe 12 is connected to the first air outlet 213; the turbine 22 pushes the air that has completed the first compression into the connecting pipe 12 through the first air outlet 213.

[0030] Please refer to Figure 1 , Figure 5 and Figure 6 .

[0031] The compression mechanism 3 is fixedly connected to the support 1. The compression mechanism 3 and the fan 2 are located at the two ends of the dual-shaft motor 11, respectively. The compression mechanism 3 includes a tapered pipe 31 and a central shaft 32.

[0032] The tapered pipe 31 is fixedly connected to the bracket 1. The tapered pipe 31 has a second air inlet 312 and a second air outlet 313. The second air inlet 312 is located on the outside of one end of the tapered pipe 31 and is connected to the other end of the connecting pipe 12. The second air inlet 312 is close to the wide end of the tapered pipe 31, and the second air outlet 313 is located at the other end of the tapered pipe 31 and is close to the narrow end of the tapered pipe 31. Air in the connecting pipe 12 is injected into the tapered pipe 31 through the second air inlet 312.

[0033] A second bearing 311 is embedded in the tapered pipe 31. The inner ring of the second bearing 311 is fitted on the outside of the central shaft 32. The central shaft 32 is rotatably connected to the tapered pipe 31 through the second bearing 311. The central shaft 32 is fixedly connected to the other output shaft of the dual-axis motor 11.

The wide end of the compression chamber 322 is connected to the second air inlet 312, and the narrow end of the compression chamber 322 is connected to the second air outlet 313. The air undergoes a second compression within the compression chamber 322. The greater the difference between the narrow end and the wide end of the compression chamber 322, the greater the air compression ratio.

[0035] The double-shaft motor 11 drives the helical blade 321 to rotate through the middle shaft 32, the helical blade 321 pushes the air to move forward in the compression cavity 322 to the second air outlet 313, the air in the compression cavity 322 is compressed twice by the tapered pipe 31 and the helical blade 321 due to the gradually narrowing compression cavity 322 and tapered pipe 31, and the compressed air is pushed out from the second air outlet 313.
