A rotor frame 3 is mounted to the stator frame 2 and has an annular first magnetic area 31 which is a magnet and mounted to the first and second induction coils 21, 22. When the stator frame 2 and rotor frame 3 have relative rotation, the first and second induction coils 21, 22 respectively cut magnetic lines and generate voltages which are respectively output from the first and second output ends 23, 24. The rotor frame 3 has a first shaft 32 which extends through the first passage 25. The rotor frame 3 further has a first connection portion 33 to which an annular second magnetic area 34 is mounted. The second magnetic area 34 is a magnet.
A separation member 4 is fixed to the case 1 and includes second lugs 41 which are located corresponding to the first lugs 11. Each second lug 41 has a second hole 42 for the bolt 13 extending therethrough and connected with the nut 14. The separation member 4 includes a second connection portion 43 which has a reception hole 44. The first connection portion 33 is engaged with the reception hole 44.
A rotatable member 5 is mounted to the separation member 4 and has a third connection portion 51 which is connected with the second connection portion 43. The third connection portion 51 has a third magnetic area 52 which is magnetically connected to the second magnetic area 34 of the rotor frame 3 while the second connection portion 43 is located therebetween. The rotatable member 5 has multiple blades 53 rotatably connected thereto and a second passage 54 is defined in the rotatable member 5 as shown in FIG. 3.
A cover 6 is fixed to the separation member 4 and has third lugs 61 which are located corresponding to the second lugs 41. Each of the third lugs 61 has a third hole 62 and multiple bolts 13 extend through the first, second and third lugs 11, 41, 61 and are connected with nuts 14 so as to connect the case 1, the separation member 4 and the cover 6 together. The cover 6 further includes a blowing passage 63 which is located corresponding to the trace of any of the blades 53 of the rotatable member 5. The cover 6 has a second shaft 64 which extends through the second passage 54.
A processor 7 is connected to the connection portion 16 of the case 1 and has a processing unit 71 and a wireless communication unit 72 which is electrically connected to the processing unit 71. The processing unit 71 is electrically connected to a first input end 73 and the first output end 23 so as to receive the voltage from the first induction coil 21. The first input end 73 is a hole. The wireless communication unit 72 is electrically connected with a second input end 74. The second input end 74 is a hole in which the second output end 24 is inserted so as to receive the voltage from the second induction coil 22. The processor 7 has a first rod 75 close to the first input end 73 and a second rod 76 close to the second input end 74. The first rod 75 is inserted into the first positioning hole 17 and the second rod 76 is inserted into the second positioning hole 18. The processor 7 further has a screen 77 and an output interface 78. The output interface 78 is a USB slot. The screen 77 and the output interface 78 are respectively and electrically connected to the processing unit 71.
As shown in FIGS. 3 and 4, when a user blows to the blowing passage 63 of the cover 6, the air pushes the blades 53 to rotate. The third magnetic area 52 of the third connection portion 51 of the rotatable member 5 is magnetically connected to the second magnetic area 34 of the rotor frame 3, while the second connection portion 43 is located there between. The rotor frame 3 is rotated by the first connection portion 33 and the first magnetic area 31 is rotated relative to the first and second induction coils 21, 22, such that the first and second induction coils 21, 22 respectively cut the magnetic lines to generate voltages. The voltages are output via the first and second output ends 23, 24, wherein the voltage from the first output end 23 is transferred to the processing unit 71 via the first input end 73. The processing unit 71 detects the change of the voltages according to the volume of the blowing air so as to transfer the change into data of the vital capacity. The data is recorded and displayed on the screen 77. The processor 7 has the output interface 78 which is electrically connected to the processing unit 71 so as to store the data of the examined vital capacity or the data vital capacity can be printed out by printing devices. The voltage from the second output end 24 can be transmitted to the wireless communication unit 72 via the second input end 74 so as to power the wireless communication unit 72. The data of the vital capacity detected by the processing unit 71 can be transmitted to a remote device for storage, recorded, analyzed and monitored by the wireless communication unit 72. Once the value of the vital capacity of the user is abnormal, the situations can be quickly handled and processed. In addition, the moisture during blowing is separated from entering the space 15 by the separation member 4, so that the parts in the space 15 can be protected from shortage or damaged.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
