Background

In many small parks, buildings such as courtyards or squares, the periphery of public buildings or amusement parks, etc. nowadays, because of being an open space outdoors, the parks cannot be cooled by using a cold air conditioner, and when the weather is clear or the sunshine is high, hot air radiated from the ground and air which is not circulated are difficult to stand, so a large amount of trees must be planted or a modeling sunshade booth must be arranged. However, trees and sunshades cannot overcome the problem that the radiant heat on the ground is not communicated with the air, and other improved technologies must be found. Among the various techniques for cooling and enhancing air convection, fans are a convenient, practical, durable, and relatively low cost technology, but small fans cannot meet the above-mentioned large space requirements. Therefore, the present inventors have proposed a plurality of air convection devices composed of large fans, such as the "air vertical convection device with protective structure" shown in taiwan patent publication No. M571913 and the "air vertical convection device capable of space landscaping" shown in No. M555409.

However, the motor of the above-mentioned air vertical convection device is a motor having a central shaft, that is, a central shaft is provided as the center of the stator, and the rotor is configured to surround the periphery of the stator, so that when the motor is installed on the vertical column, the vertical column must be divided into two sections, whereby the lower end of the central shaft of the motor is fixed to the upper end of the lower vertical column, and the upper end of the central shaft of the motor is connected to another upper vertical column or other structures, so that the solar panel, the protective cover, the mounting seat of the communication equipment, or the like can be installed above the motor, and thus, this configuration causes many assembly troubles and the assembly configuration is complicated. Furthermore, if the motor with the central shaft is installed on the existing street lamp, sign lamp, flag pole, building post, telegraph pole or tree, the existing pole body must be cut into two sections, and the large fan can be installed in the above manner, which causes the problem that the pole body must be replaced completely.
