Description

rotatable fan

Technical field

The utility model relates to the field of fans, specifically a rotatable fan.

Background technique

Fans are an essential electrical appliance in modern homes, and they are also the main way that Chinese residents rely on themselves to cool down and escape the heat in the hot summer.

In order to increase the blowing area of the fan, the fan heads of some current fans can be rotated. However, the current fan heads are generally set horizontally and then rotate around the vertical axis, so that the fan heads cannot blow air upward or downward when rotating. This makes the use of the fan less effective.

Utility model content

The technical problem to be solved by this utility model is to provide a rotatable fan, which allows the fan head to rotate 360 degrees and has a wide blowing range when the fan head rotates.

In order to solve the above technical problems, the utility model provides a rotatable fan, including a mounting base and a fan head;

The fan head is rotatably mounted on the mounting base, and the rotation axis of the fan head forms an acute angle with the central axis of the fan head;

The rotation axis of the fan head forms an acute angle with the horizontal plane;

A driving mechanism for driving the fan head to rotate is provided in the mounting base.

Preferably, the mounting base includes a mounting plate, a rotating member is rotatably provided on the mounting plate, the fan head is connected to the rotating member, and the driving mechanism is used to drive the rotating member to rotate.

Preferably, the driving mechanism includes a large gear, a pinion gear and a motor. The large gear is coaxially fixedly connected to the rotating member, the large gear meshes with the pinion gear, and the output shaft of the motor is connected to the pinion gear.

Preferably, the fan further includes a base and a support rod whose length can be adjusted by telescopicity. The lower end of the support rod is fixedly connected to the base, and the upper end of the support rod is detachably connected to the mounting base.

Preferably, the mounting base is provided with a first connection part, and the upper end of the support rod is provided with a second connection part for threaded connection with the first connection part.

After adopting the above structure, compared with the existing technology, the utility model has the following advantages:

In the fan of the present invention, the fan head can rotate, and since the rotation axis of the fan head and the central axis of the fan head form an acute angle, and the rotation axis of the fan head forms an acute angle with the horizontal plane, the fan head rotates When the fan head is turned on, the fan head can blow air in the horizontal direction or upward, so that the blowing range of the fan head is wider, so that the use effect of the fan is better.

Figure 3 is a schematic structural diagram of the fan head of the present invention when it is rotating.

Detailed ways

The utility model will be described in further detail below in conjunction with the accompanying drawings and specific implementation modes.

As shown in Figures 1 and 3, the rotatable fan of the present invention includes a mounting base 10, a fan head 20, a support rod 30 and a base 40.

The fan head 20 is rotatably disposed on the mounting base 10 , and an acute angle is formed between the rotation axis of the fan head 20 and the central axis of the fan head 20 .

The rotation axis of the fan head 20 forms an acute angle with the horizontal plane.

The mounting base 10 is provided with a driving mechanism for driving the fan head 20 to rotate.

Referring to FIG. 1 , when the fan head 20 is not rotating, the central axis of the fan head 20 is set horizontally, and the rotation axis of the fan head 20 forms an angle of 45 degrees with the central axis of the fan head 20 . In this way, when the fan head 20 is rotating, , the blowing direction of the fan head 20 will be horizontally or upward, so that the blowing range of the fan head 20 is wider.

The mounting base 10 includes a mounting plate 11, and a rotating member 12 is rotatably provided on the mounting plate 11. The fan head 20 is connected to the rotating member 12, and the driving mechanism is used to drive the rotating member 12 to rotate. In this way, the fan head is installed. At 20 o'clock, install the fan head 20 on the mounting plate 11 and fix the fan head 20 to the rotating member 12 .

The driving mechanism includes a large gear 13, a small gear 14 and a motor 15. The large gear 13 is coaxially fixedly connected to the rotating member 12, the large gear 13 meshes with the small gear 14, and the output shaft of the motor 15 is connected to the small gear 14. In this way, when the motor 15 is working, the motor 15 drives the small gear 14 to rotate, the small gear 14 drives the large gear 15 to rotate, and the large gear 15 drives the rotating member 12 to rotate, thereby driving the fan head 20 to rotate, making the driving mechanism simple in structure and easy to install. .

The support rod 30 is a telescopic rod, and the length of the support rod 30 can be adjusted by telescopicity. The lower end of the support rod 30 is fixedly connected to the base 40 , and the upper end of the support rod 30 is detachably connected to the mounting base 10 . In this way, the support rod 30 can be adjusted by length to adjust the height of the fan head 20.

The mounting base 10 is provided with a first connection part 16, and the upper end of the support rod 30 is provided with a second connection part 31 for threaded connection with the first connection part 16. In this way, the connection between the installation base 10 and the support rod 30 is It is more convenient to disassemble and assemble the room.

A sliding contact power supply structure can be used between the mounting base 10 and the fan head 20 to provide power to the motor in the fan head 20 .

The above only describes preferred examples of the application of the present utility model, but it cannot be understood as limiting the claims. The structure of the present utility model can have other changes and is not limited to the above structure. In short, all changes made within the protection scope of the independent claims of the present utility model are within the protection scope of the present utility model.
