The support column 32 of the unit 3 pivots to perform a pitching movement. The pitch adjusting body 34 allows the fan main body 41 of the air supply unit 4 to move between a horizontal air supply position 411 and a vertical air supply position 412. The fan body 41 is at the horizontal air blowing position 411, which can blow air horizontally like a general electric fan. When the fan body 41 of the air blowing unit 4 is at the vertical air blowing position 412, the pitch adjusting body 34 is supported against the elevation angle and against the wall 33, so that the fan main body 41 can blow air vertically upwards.

In FIG. 9, the fan body 41 drawn in dashed lines is located at the horizontal air supply position 411, and the fan main body 41 drawn in solid lines is located at the vertical air supply position 412. Since the pitch adjustment body 34 can pivot relative to the support column 32, the The fan body 41 can rotate at a pitch angle 61 relative to the support column 32, and the rotation range of the pitch angle 61 can reach 90 degrees. In addition, since the fan body 41 is provided with a yaw mechanism, the fan body 41 can be relatively The pitch adjusting body 34 rotates at a yaw angle 62, and the rotation range of the yaw angle 62 can reach 80 degrees.

However, when the fan body 41 is located at the vertical air blowing position 412, the weight of the fan body 41 has all moved to the right side of the top of the support column 32, and when the fan body 41 drives the air to be sent upward, it will be on the fan body 41. The force that generates the downward pressure, the addition of the two forces will cause the overall center of gravity of the fan device to shift to the right position. Generally, the fan will fall over in this situation. In order to stabilize the center of gravity of the fan device, the battery 53 is arranged in the base 31 and not directly in the support column 32, so that the base 31 can rely on the weight of the battery 53 to pull the center of gravity of the fan main body 41 caused by shifting, so that the fan main body 41 can be shifted. When the vertical air supply position 412 is operated, or even when the yaw angle 62 is operated again, no tipping will occur.

From the above description, it can be known that the fan device of this new type does have the following effects:

1. The setting location is not limited:

The control unit 5 is provided with the battery 53 in the base 31, which can store the operating power of the control module 51 and the fan main body 41. Based on the power provided by the battery 53, the electric fan device can move at any position and operate. The setting position is not limited by the socket position or the length of the wire.

2. It can provide vertical upward air supply:

The pitch adjusting body 34 can rotate relative to the support column 32, and drive the fan body 41 to move between the horizontal blowing position 411 and the vertical blowing position 412. When the fan body 41 is at the vertical blowing position 412, it can drive air Blow to the upper side of the fan unit to provide vertical upward blowing.

3. Prevent dumping:

When the fan body 41 is at the vertical air supply position 412 and blows air upwards vertically, the center of gravity of the fan device will be biased to the side of the support column 32, and the battery 53 can effectively lift the weight of the base 31, thereby pulling the The center of gravity caused by the fan main body 41 is shifted, and the situation of toppling is prevented.

In summary, the pitch adjusting body 34 can rotate relative to the support column 32 to provide the fan body 41 with respect to the support column 32 to move between the horizontal air supply position 411 and the vertical air supply position 412, and at the vertical air supply position 412 When air is blown upwards vertically, the fan body 41 can be rotated relative to the support column 32 at the pitch angle 61 and the yaw angle 62, which can provide more variable air supply angles, and the battery 53 arranged on the base 31 can be stable The center of gravity of the fan device is to avoid dumping. The battery 53 can also provide the power for the fan device to operate, so that the installation position of the fan device will not be restricted by the position of the socket or the length of the wire. The base 31 can be separated The ground is combined with the support column 32 to facilitate the user to replace the battery, so it can indeed achieve the purpose of cost innovation.

However, the above is only a preferred embodiment of the present model, and should not be used to limit the scope of implementation of the present model, that is, simple equivalent changes and modifications made in accordance with the scope of the patent application for the present model and the description of the model , Are still within the scope of this new patent.
