Further, please refer to FIG. 4, which is a schematic diagram of the internal structure of the airflow device group 12 of the first embodiment of the present invention. In this embodiment, the airflow device group 12 includes a first axial flow device 121 and a second axial flow device 123. The second axial flow device 123 is disposed between the first axial flow device 121 and the base 10, where In the embodiment, the screen structure 14 is disposed between the base 10 and the second axial flow device 123 of the airflow device group 12. The first axial flow device 121 includes a first shaft body 1210 and a plurality of first blades 1212. The first shaft body 1210 has a first axis X1, and the plurality of first blades 1212 respectively protrude radially from the first axis. The body 1210, that is, the plurality of first blades 1212 protrudes from the first shaft body 1210 in a radial direction of the first shaft body 1210, wherein the radial direction is perpendicular to the first axis X1. The second axial flow device 123 includes a second shaft body 1230 and a plurality of second fan blades 1232. The second axial flow device 123 is disposed in series with the first axial flow device 121, that is, the second shaft body 1230 has a second The axis X2 is assembled on the first axial flow device 121 in such a manner that the second axial flow device 123 is substantially aligned with the first axis X1 of the first axial flow device 121 during assembly. In addition, the plurality of second blades 1232 respectively protrude radially from the second shaft body 1230, that is, the plurality of second blades 1232 protrude from the second shaft body 1230 in a radial direction of the second shaft body 1230, wherein The radial direction is perpendicular to the second axis X2.

As shown in FIGS. 1 to 4, when the first shaft body 1210 drives the plurality of first blades 1212 to rotate along a first direction R1, the plurality of first blades 1212 are parallel to one of the first axes X1. The air inlet direction Y generates a flow F by a first pressure, and when the first shaft 1210 drives the plurality of first blades 1212 to rotate along the first direction R1, the second shaft 1230 drives the plurality of second blades 1232. A plurality of second blades 1232 are rotated along a second direction R2 opposite one of the first directions R1. In other words, when the present creative transport vehicle 1 is in operation, the steering of the second blade 1232 of the second axial flow device 123 is opposite to the steering of the first blade 1212 of the first axial flow device 121, that is, the original airflow The device group 12 is a double reverse axial flow device group.

As described above, when the first shaft 1210 of the first axial flow device 121 drives the first blade 1212 to rotate along the first direction R1, the first blade 1212 can follow the wind direction Y parallel to the first axis X1. A gas flow F having the first pressure is generated, and the gas flow F having the first pressure is sent to the second axial flow device 123. Then, the airflow F enters the second axial flow device 123. At this time, the second shaft body 1230 of the second axial flow device 123 rotates the plurality of second blades 1232 along the second steering R2 opposite to the first steering R1 to make a plurality of The two blades 1232 can further feed the airflow F into the hollow chamber 101 at a second pressure in the wind direction Y.

In other words, in this embodiment, the transporting carrier 1 pressurizes the airflow F generated by the first axial flow device 121 by the second axial flow device 123 stacked on the first axial flow device 121 to pressurize Airflow F entering the hollow chamber 101.

It is worth mentioning that the airflow F sent by the plurality of second blades 1232 at the second pressure enters the hollow chamber 101 via the screen structure 14, whereby the airflow F entering the hollow chamber 101 can be filtered. The structure 14 is filtered to achieve the efficacy of the clean airflow F and conforms to the environmental specifications of the operational site of the inventive transport vehicle 1. When the airflow F sent by the plurality of second blades 1232 at the second pressure enters the hollow chamber 101 via the screen structure 14, the partial airflow F1 is ejected through the plurality of vent structures 103 to generate a lifting force, and then push The lifting plate member 2 is above the base 10, and the other portion of the airflow F2 is ejected in a direction not perpendicular to the upper surface via the gap G of the plurality of flow channel structures 105. The plate member 2 is adjacent to the respective channel structures 105 due to the airflow F2. The air in the space between the base 10 and the base 10 is taken out in a direction not perpendicular to the plate member 2. According to the white effort law, the air flow F2 causes the pressure on the lower side of the plate member 2 to be smaller than the pressure on the upper side, thereby causing the plate member 2 The upper and lower sides create a pressure difference between the plate member 2 and the base member 10, so that the pressure difference caused by the airflow F2 to the plate member 2 can be balanced with the lift force provided by the airflow F1 to the plate member 2. In order to maintain a stable spacing between the plate member 2 and the base 10. In addition, in this embodiment, the gap G may be smaller than a hole diameter D of each of the air hole structures 103, whereby the flow rate of the air flow F2 flowing through the gap G is greater than the flow rate of the air flow F1 flowing through each of the air hole structures 103 to accelerate the above Balance process.
