Drawings
For purposes of illustration and not limitation, the present invention will now be described in accordance with its preferred embodiments, particularly with reference to the accompanying drawings, in which:
fig. 1 is a schematic view of an external shape of an electric fan according to an embodiment of the present invention;
fig. 2A and 2B are schematic views of an operating state of an electric fan according to an embodiment of the present invention.
Detailed Description
Embodiments of the present invention will be described below with reference to the accompanying drawings. Fig. 1 is a schematic view of an external shape of an electric fan according to an embodiment of the present invention.
The electric fan in fig. 1 includes a fan head 1, a stay 2, and a base 3. The fan head 1 has a cylindrical portion 11 and a circular table portion 12 coaxially connected, both connected to a larger bottom surface of the circular table portion 12, as shown in the drawing. The two ends of the strut 2 are respectively connected with the fan head 1 and the base 3. The base 3 may take a conventional flat shape and the upper and lower surfaces may be circular, the upper surface having a diameter of between 245mm and 249 mm; the lower surface may be slightly smaller in diameter, which is aesthetically pleasing. The upper surface of the base 3 plays a role of an operation panel of the electric fan, and is provided with a plurality of function buttons which can send various operation signals.
In order to visually coordinate the dimensions of the fan head 1 with the base 3, the diameter of the cylindrical portion 11 of the fan head 1 may be between 255mm and 265 mm. In addition, the height of the circular table portion 12 may be between 40mm and 50 mm. For example, the upper surface of the base 3 has a diameter of 247.5mm and the cylindrical portion 11 has a diameter of 260mm and the height of the circular truncated cone portion 12 is 45 mm. The included angle between the generatrix of the circular table portion 12 and the axis of the circular table portion 12 is 45 degrees.
With a typical fan, the fan head can swing to provide a wide range of air supply. The electric fan in the embodiment of the utility model has the function of swinging the head. A rotating assembly (not shown in the figure) is arranged in the supporting column 2, the rotating shaft of the rotating assembly is perpendicular to the circular table surface of the circular table part 12, and when the rotating shaft of the rotating assembly rotates, the circular table part 12 and then the whole fan head 1 are driven to swing. Fig. 2A and 2B are schematic views of an operating state of the electric fan according to the embodiment of the present invention, respectively showing different positions of the fan head 1 during the swinging process.
Taking fig. 1 as an example of the initial position, the axis of the fan head 1 (i.e. the common axis of the cylindrical portion 11 and the circular truncated cone portion 12) is parallel to the upper and lower surfaces of the base 3, i.e. the fan head 1 is in a vertical state. If the fan is arranged on the desktop, the fan sends out wind in the horizontal direction at the moment.
When the rotation axis of the rotating assembly rotates 1/2, the fan head 1 is in a flat state as shown in fig. 2A, and the axis thereof is perpendicular to the upper and lower surfaces of the base 3, and sends out wind in a vertical direction. When the rotation is continued for one week, the state of fig. 1 is returned. Fig. 2B shows the fan head 1 in a position between vertical and horizontal, through which it passes when the rotating assembly is rotated.
When the electric fan is used, the fan blades rotate by pressing the starting button; therefore, when the head swinging button is in a pressed state, the head swinging is started at the same time, if the head swinging button is not in the pressed state, the fan head keeps the current state, and a user can press the head swinging button again when the head swinging is needed.
If the fan head 1 is required to maintain a certain state during use, the corresponding control button can be pressed to stop swinging immediately during swinging. In daily use, there may be a greater demand for horizontal or vertical wind, for which purpose corresponding control buttons may be provided for signalling a forward or upward blowing operation.
Thus, no matter whether the fan head 1 swings or not, if the fan head 1 receives the upward blowing operation signal, the fan head 1 swings to a state that the axis is vertical to the upper and lower surfaces of the base 3 and then keeps; similarly, if a forward blowing operation signal is received, the axis of the fan head 1 is maintained in a state of being parallel to the upper and lower surfaces of the base 3 and then maintained.
The above button function setting is only an example, and other modes can be adopted in the implementation, and the button function setting is set in a controller of the electric fan as a program, and the controller receives an operation signal and sends a control instruction to control actions such as fan blade rotation and fan head swing.
In the prior art, the fan head of the electric fan is usually controlled by horizontal swinging and up-down nodding swinging separately, and two sets of driving mechanisms are required. And according to the utility model discloses an embodiment, rotating assembly drives from the round platform face part of fan head, only needs one set of actuating mechanism can accomplish swing by a relatively large margin like this to realize the air supply on a relatively large scale, and relatively power saving. Under the condition that the included angle between the generatrix of the circular table part and the axis is 45 degrees, the horizontal air supply state and the vertical air supply state can be passed through in a continuous rotation period, so that the fan can be stopped in the states at any time when swinging, and the operation of a user is more convenient to realize the horizontal air supply and the vertical air supply.
The above detailed description does not limit the scope of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions can occur, depending on design requirements and other factors. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
