In the embodiment of the present application, the outer surface of the grille 21 has the operation panel 22, and the position of the operation panel 22 is not particularly limited, for example, as shown in fig. 2, the operation panel 22 is located on the outer surface of the grille 21, and the orientation of the operation panel 22 is perpendicular to the direction of the support bar 3.

Specifically, the grill 21 includes a front grill 211 and a rear grill 212, so that the front grill 211 and the rear grill 212 together form a substantially cylindrical inner space in which components such as a motor and fan blades can be accommodated.

An operation panel 22 is provided at the center of the front grill 211, and a slide control unit 23 is provided between the front grill 211 and the operation panel 22. When the electric fan 1 needs to be controlled, the operator can slide the operation panel 22, and the slide control unit 23 controls the electric fan 1 based on the slide operation of the operation panel 22. In the illustrated preferred embodiment, the operation panel 22 is located on the outer surface of the center of the front grill 211 so that the arrangement of the operation panel 22 does not increase the resistance to the airflow.

In another alternative embodiment, as shown in fig. 4, the outer surface of the grille 21 has an operating panel 22 in the shape of a ring.

For example, as shown in fig. 4-6, the grill 21 includes a front grill 211 and a rear grill 212, the front grill 211 and the rear grill 212 together form an inner space capable of accommodating components such as a motor and fan blades,

a slide control unit 23 is provided between the ring-shaped operation panel 22 and the grill 21. When the electric fan 1 needs to be controlled, the operator can slide the operation panel 22, and the slide control unit 23 controls the electric fan 1 based on the slide operation of the operation panel 22.

Of course, the above embodiments are only examples of the positions of the optional operation panels 22, and there are other embodiments of the positions of the optional operation panels 22, for example, the position is located at the center of the rear side of the rear grill 212 without departing from the scope of the present invention, and the detailed description thereof is omitted here.

As shown in fig. 2 and 3, schematic diagrams of the grille 21, the operation panel 22 and the flexible circuit board 5 provided with the sliding control unit 23 of the electric fan 1 of the present invention are exemplarily shown.

The operator panel 22 may be located elsewhere on the grill 21, for example, as shown in fig. 4-6, the operator panel 22 may be annular, located on a ring 213 disposed on the periphery of the grill 21, or the operator panel 22 may be centrally located on the rear side of the rear grill 212 without departing from the scope of the present invention.

In the embodiment of the present application, in order to facilitate the operation, an area where the slide control operation can be performed is provided on the operation panel 22, and for example, as shown in fig. 2 to 4, a slide control operation area 221 is provided on the operation panel 22; likewise, in order to receive a slide operation instruction, the slide operation region 221 corresponds to the slide control unit 23.

Specifically, the slide control unit 23 is configured by a plurality of slide touch sensing elements 231, and the slide control unit 23 receives a slide control signal generated by a slide operation from the slide control operation area 221 through the slide touch sensing elements 231.

Each of the sliding touch sensing elements 231 can sense a sliding operation of an operator. The positions of the plurality of sliding touch sensing elements 231 and the sliding operation area 221 correspond to each other. In the illustrated embodiment, a plurality of sliding touch sensing elements 231 are linearly and continuously arranged with each other on the sliding control unit 23. It should be understood that the plurality of sliding touch sensitive elements 231 can be arranged in other manners, such as being arranged in series along a circle, arc, etc.

The sliding control unit 23 may be configured to determine the variation mode of the operating parameter of the electric fan 1 to be adjusted according to the sequential triggering relationship of the sliding touch sensing elements 231. The operating parameter may be, for example, an air volume parameter of the electric fan, an electric fan swing parameter, an electric fan mode parameter, an operating time parameter of the electric fan, and the like. For example, in the case that the operation parameter is an air volume parameter, when the operator slides in one direction in the slide control operation area 221, the slide control unit 23 may determine the sliding direction according to the sequential trigger relationship of the sliding touch sensing elements 231, so as to determine whether to increase or decrease the air volume according to the sliding direction. If the operating parameter is an operating time parameter, then the operating time of the electric fan can be increased or decreased depending on the direction of sliding. When the operation parameter is an electric fan swing parameter, whether the electric fan swings or not may be determined according to the sliding direction.

In an alternative embodiment, the air volume is increased when the operator slides towards one end of the slide control operation region 221 and decreased when sliding towards the other end. However, the present invention is not limited to this, and as described above, when the sliding touch sensing elements 231 are arranged in series along a circle, the air volume may be increased when the operator slides in the slide control operation region 221 in the clockwise direction, and may be decreased when the operator slides in the counterclockwise direction, for example. Alternatively, the fan swing parameter is adjusted to yes when the operator slides in the clockwise direction and to no when the operator slides in the counterclockwise direction. It should be understood that when the operation parameter is an electric fan mode parameter or an operation time parameter, it may be set as desired that the slide control unit 23 performs corresponding adjustment of the relevant parameter according to the direction of the sliding operation.

Likewise, when the sliding touch sensing elements 231 are arranged in series along the rectangle, the air volume may be increased when the operator slides the slide-control operation region 221 along a first direction of the rectangle, for example, and decreased when sliding along a second direction, for example, wherein the first direction may be a direction set along the length or width of the rectangle, and the second direction is a direction in which the first direction is disposed opposite to the second direction. Alternatively, the fan swing parameter is adjusted to yes when the operator slides in the first direction and is adjusted to no when the operator slides in the second direction. It should be understood that when the operation parameter is an electric fan mode parameter or an operation time parameter, it may be set as desired that the slide control unit 23 performs corresponding adjustment of the relevant parameter according to the direction of the sliding operation.

Furthermore, the sliding control unit 23 may be further configured to determine the distance of the sliding operation according to the distance between the touch sensing elements 231 that are triggered first and last, thereby determining the amount of change of the operation parameter. For example, the amount of increase or decrease in the air volume is adjusted according to the sliding distance, the length of increase or decrease in the fan operating time is adjusted, and the like.

Illustratively, as shown in fig. 3 and 4, a point-touch control unit 24 is further provided between the grille 21 and the operation panel 22, and the point-touch control unit 24 is configured to control the operation of the electric fan 1 based on the point-touch control of the operation panel 22.

And the other one of the touch manipulation regions 222 is provided with a natural wind mode key and a power key. It should be understood that the number and location of the keys of the touch manipulation area 222 may be set in any manner as desired.

In an alternative embodiment, each touch control subunit 242 corresponds to one control method of the touch control unit 24, but it should be understood that each touch control subunit 242 may be used to perform more than one control method, such as one for triggering in fan mode, run time, etc.

In the embodiment shown in fig. 2, both the touch control unit 24 and the slide control unit 23 are provided on the same flexible circuit board 5. In this utility model, it can be more conveniently and more snugly set up between control panel and grid 21 to adopt flexible circuit board 5. It should be understood that the touch control unit 24 and the slide control unit 23 may be provided on a rigid circuit board corresponding to the shape of the operation panel, which is matched to the control panel and the grill 21.
