Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a double-shaking fan. Background Art

[0002] In daily life, wall-mounted fans and floor-standing fans are increasingly used. However, conventional fans can only move left and right, which limits the air supply range and cannot meet the user's demand for all-round comfortable air supply. In order to expand the air supply range and enable the fan to move up and down and left and right, a specific shaking structure design needs to be added to the outside of the motor.

[0003] Most fans on the market can only swing left and right automatically, and the vertical angle adjustment requires additional manual adjustment. This design is not only inconvenient to operate, but also cannot swing up and down, left and right at the same time during the operation of the fan. This limitation limits the use of fans, especially in large spaces or when hot and cold air needs to be distributed quickly and evenly. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a double oscillating fan, which can increase the range of air supply and improve the air circulation efficiency.

[0005] A double oscillating fan according to the first embodiment of the utility model comprises:

[0006] A machine base is provided with a mounting portion;

[0007] A fan motor is rotatably mounted on the mounting portion, and the fan motor is suitable for mounting fan blades and driving the fan blades to rotate;

[0008] A first motor is installed on a side of the base away from the fan motor, the first motor is in transmission connection with the base, and the first motor is suitable for driving the base to rotate horizontally;

[0009] The second motor is installed on one side of the fan motor. The second motor is drivingly connected to the base. The second motor is suitable for driving the base to rotate vertically.

[0010] A dual-oscillating fan according to an embodiment of the utility model has at least the following beneficial effects: by driving the base to rotate horizontally by the first motor and driving the base to rotate vertically by the second motor, all-round adjustment of the fan air supply angle is achieved, which greatly improves the air supply range and air circulation efficiency, and provides users with a more comfortable and balanced air environment. The user does not need to manually adjust the angle of the fan, and the dual-oscillating fan can automatically complete the horizontal and vertical shaking movements during operation, which simplifies the operation process and improves the user experience. By independently driving the first motor and the second motor, the fan's shaking mode can be flexibly adjusted according to actual needs, such as only turning on the horizontal shaking, only turning on the vertical shaking, or turning on both at the same time, to meet the needs of different scenarios.

[0011] According to some embodiments of the utility model, a mounting hole is provided on a side of the base away from the mounting portion, a steel sleeve is rotatably provided in the mounting hole, the base is rotatably mounted on the vertical pole through the steel sleeve, and the first motor drives the base to pivot with the vertical pole. The design of the steel sleeve reduces the direct friction between the base and the vertical pole, which helps to reduce the noise level of the fan during operation. Through the cooperation of the steel sleeve and the vertical pole, the installation and removal of the fan becomes simpler and faster, which is convenient for users to adjust the position or perform cleaning and maintenance as needed.

[0012] According to some embodiments of the utility model, the first motor further comprises a first cam, the output shaft of the first motor is in driving connection with the first cam, and the first cam is in driving connection with the steel sleeve. The first cam helps to adjust the air supply angle of the fan, and can convert the full circular motion of the motor into a small amplitude motion, so as to achieve more delicate and accurate air supply angle control and improve the air supply effect. The direct transmission connection between the first cam and the steel sleeve helps to reduce vibration and noise during the motion process and enhance the stability of the base when it rotates horizontally.

[0013] According to some embodiments of the utility model, the first motor further includes a first connecting rod, the first connecting rod is arranged between the first cam and the steel sleeve, one end of the first connecting rod is connected to the first cam, and the other end is connected to the steel sleeve. The design of the first connecting rod makes the transmission system more compact, helps to reduce the overall size of the fan, and makes it more suitable for use in a limited space.

[0014] According to some embodiments of the utility model, the first cam is detachably connected to the output shaft of the first motor. The first cam is detachably connected to the first motor, which is convenient for replacing different cams, thereby obtaining different air supply angles of the fan, and facilitating the fan to be used in different working conditions.

[0015] According to some embodiments of the utility model, the second motor further includes a second cam, the output shaft of the second motor is in driving connection with the second cam, and the second cam is in driving connection with the base.

[0017] According to some embodiments of the utility model, the second cam is detachably connected to the output shaft of the second motor, thereby reducing maintenance costs, and the disassembly and assembly process can be completed without complicated tools, simplifying the maintenance process and reducing the requirements for professional skills.

[0018] According to some embodiments of the utility model, a wire passing hole is further provided in the base, and a wire passing coil is sleeved in the wire passing hole. The design of the wire passing coil can effectively protect the wires passing through the inside of the base and prevent the wires from being worn or damaged.

[0019] According to some embodiments of the utility model, a washer is provided at the abutment between the mounting portion and the fan motor. The provision of the washer can effectively reduce direct contact between the fan motor and the mounting portion when rotating, thereby reducing wear and extending the service life of the fan motor and the mounting portion.
