Description

The present invention relates to the field of small household appliances, and particularly to a multi-angle swing type blower.

An electric fan is one that generates wind on a hot day to get a cool feeling. An electric fan is a device that is driven by electric power to generate an air flow, and when the power is turned on, the built-in blades rotate to generate natural wind and achieve the effect of obtaining a cool feeling. The low energy consumption and environmentally friendly electric fan can promote the air circulation in the room and achieve the effect of lowering the temperature, which is very useful for the human body.

A conventional electric fan usually has a left-right swing function, but does not have a vertical swing function, and such a conventional fan does not have a sufficiently wide blowing range.

As described above, since the conventional electric fan has a narrow ventilation range, there is a problem that the air circulation area in the room is reduced, that is, the temperature of a part of the space cannot be lowered and the cool feeling for the user is lowered. It was. The present invention has been made in view of the above problems, and its purpose is to have a wider blowing range than a conventional fan, adjust the swing width, and thereby change the blowing range, and actually It is to provide a multi-angle swing type blower that can generate different angles of wind by making maximum use of the blower according to the scene, enhance the user's comfort, and improve the user's coolness. ..

According to one aspect of the present invention, a multi-angle swing type blower is provided, which includes a pedestal, a fixed rod, a blower mechanism, a horizontal swing mechanism and a vertical swing mechanism, and one end of the fixed rod is fixed to the pedestal.
