Description

Vertical duct fan with adjustable air flow direction

The present invention is an electric fan with adjustable air outlet direction, in particular, an upright duct electric fan whose air outlet direction can be adjusted 360 degrees.

As shown in FIG8 , there is a vertical duct fan 90 on the market. The vertical duct fan 90 has a columnar duct 91. A strip-shaped air outlet 92 is formed on one side of the columnar duct 91 along the vertical axis. A housing is provided below the columnar duct 91. A blower is provided in the housing. The user can operate the blower to make the air flow out of the air outlet 92 of the columnar duct 91.

Among them, since the vertical duct fan 90 has only one long air outlet 92, the vertical duct fan 90 can only blow air in the same direction, and the air cannot be blown in other directions, which is inconvenient to use. Therefore, it is necessary to install a rotating device 93 at the bottom of the vertical duct fan 90. The rotating device 93 can rotate and swing the vertical duct fan 90 through a motor component, and change the direction of the air outlet 92 through rotation, so that the vertical duct fan 90 can blow air in different directions.

However, since the air outlet 92 of the rotary upright fan only has one long strip-shaped air outlet 92 and can only discharge air in one direction, when the rotary mechanism rotates the upright duct fan 90, it can only rotate within a limited angle range, which is not practical. In addition, the structure of the rotary device 93 is relatively complex and has motor components, which increases the cost. There is still room for improvement.

The main purpose of the present invention is to provide a vertical duct fan with adjustable air outlet direction, hoping to improve the shortcoming of the current vertical duct fan that cannot discharge air in different directions at the same time. The present invention has the advantages of simple structure and low cost.

A vertical duct fan with adjustable air outlet direction comprises: a housing, a housing formed inside thereof, an air outlet connected to the housing space formed at the top of the housing, the housing having a side wall surrounding the housing space, the side wall having a plurality of air inlet holes connected to the housing space; an air outlet duct detachably arranged at the top of the housing, and comprising a plurality of ducts that can be detached from each other in a vertical direction and can pivot with each other in a horizontal direction. The interior of the plurality of tubes is connected to form an air supply duct, the air supply duct is connected to the air supply port of the housing, one end of each tube is formed with a connecting portion, the connecting portion can extend into another tube, each tube is formed with at least one air outlet connecting the air supply duct and the external environment; and a blower device is arranged in the housing and located in the accommodation space, the blower device can supply air to the air supply duct of the air outlet pipe through the air supply port.

The blower device of the vertical duct fan with adjustable air outlet direction of the present invention can extract gas through the air inlet of the housing, and send the gas into the air supply duct of the air outlet duct through the air supply port of the housing, so that the gas can be blown to the outside through the air outlets of the multiple tubes. The vertical duct fan with adjustable air outlet direction has the following advantages:

1. Improved convenience of use: As mentioned above, the vertical duct fan with adjustable air outlet direction will blow air from the air outlets of the multiple tubes to the external environment. Since the multiple tubes can be disassembled and pivoted with each other, the user can direct the air outlets of the multiple tubes to different directions according to usage requirements, so that the vertical duct fan with adjustable air outlet direction can discharge air in different directions at the same time, and the number of the tubes can be increased or decreased according to usage requirements, effectively improving the convenience of use.

2. Reduce costs: The pivotable design between the multiple tubes of the air outlet duct allows the vertical duct fan with adjustable air outlet direction to discharge air in different directions at the same time. Since the air outlet duct has a simple structure and is only composed of mechanical components, it can discharge air in different directions at the same time without the need for additional motors or other electrical components to drive the rotation, which can effectively reduce costs, improve the convenience of maintenance, and does not require additional electricity consumption.
