Description

Technical Field

[0001] The utility model belongs to the technical field of fans, and in particular relates to a fan with an adjustable rotation range. Background Art

[0002] The fan can swing left and right, up and down to supply air independently, and can also rotate and swing in three dimensions to simultaneously supply air left and right, up and down, which is used to expand the air supply range and effectively improve air circulation.

[0003] For example, publication number CN105134631A discloses a fan head, a vertical and wall-mounted fan, a household appliance, and a blowing method, wherein the vertical fan includes a fan head, a bracket for supporting the fan head, and a curved portion connecting the bracket and the fan head, the bracket extending in the vertical direction, the curved portion including a columnar mounting portion away from the bracket, and the central axis of the mounting portion being inclined relative to the bracket. A rotating structure is provided in the mounting portion, the rotating structure including a second rotating shaft, a second motor, a first gear, a second gear, and a third rotating shaft, and the second rotating shaft is perpendicular to the central axis of the mounting portion. Because the first gear is connected to the third rotating shaft, the second gear is connected to the second rotating shaft, and the second gear is meshed with the first gear, the second motor drives the third rotating shaft and the first gear to rotate, driving the second gear and the second rotating shaft to move together. Because the first axis of the fan head and the second rotating shaft are arranged at an angle, the second rotating shaft drives the fan head to rotate three-dimensionally within the spatial range formed in the horizontal and vertical directions.

[0004] However, the curved section needs to tilt to bear the weight of the entire fan head, and the mounting portion of the curved section has a rotating structure, which is complex. To ensure the stable rotation of the fan head, the processing of the curved section and the assembly of internal parts require very high precision, resulting in high production costs and difficulty in implementation.

[0005] The Chinese patent document with publication number CN214196717U discloses a desktop circulating fan, comprising a base provided with a pillar with an axis extending up and down; a rotary drive unit mounted on the upper end of the pillar, the rotary drive unit having a rotary output shaft, the angle between the axis of the rotary output shaft and the axis of the pillar being an obtuse angle; a fan assembly comprising a wind cover body, a wind wheel, and a fan motor, the fan motor being mounted on the wind cover body, the fan motor having a rotary output shaft coaxially connected to the wind wheel, the rotary output shaft being transmission-connected to the wind cover body, the angle between the axis of the rotary output shaft and the axis of the rotary output shaft being an obtuse angle.

[0006] In the technical solution of the above patent document, the angle between the axis of the rotating output shaft and the axis of the rotating output shaft, as well as the angle between the axis of the rotating output shaft and the axis of the support are both obtuse angles. The rotating drive unit drives the wind hood body to rotate around the axis of the rotating output shaft through the rotating output shaft, so that the wind hood body can rotate and swing in three-dimensional directions left and right, up and down, thereby realizing the three-dimensional air supply of the circulation fan. The structure is relatively simple, and the difficulty of processing and assembly is reduced. However, the axes of the rotating output shaft of the rotating drive unit and the rotating output shaft of the wind hood body are fixed at an obtuse angle, and the wind hood body can only rotate in three dimensions around the axis of the rotating output shaft. It is impossible to adjust the angle to change the rotating blowing range of the circulation fan according to the different blowing needs of the user, and does not meet the diversified blowing needs of the market. Utility Model Content

[0007] The purpose of the utility model is to provide a fan with an adjustable rotation range, so as to solve the problem that the existing three-dimensional rotating fan cannot adjust the angle between the fan and the rotating shaft, resulting in the inability to change the three-dimensional rotating blowing range of the fan and the inability to meet the different blowing needs of users.

[0008] To achieve the above-mentioned purpose, an embodiment of the present invention provides a fan with an adjustable rotation range, comprising a base, a fan body and a rotation drive mechanism, wherein the bottom end of the base is provided with a support surface, and the upper end is provided with a mounting surface, and the rotation drive mechanism is arranged in the base, and the rotation drive mechanism includes a drive shaft extending out of the mounting surface, and the drive shaft and the support surface form an angle of 30° to 60°; an adjustment mechanism is provided between the drive shaft and the fan body, so that the fan body is connected to the drive shaft, and the adjustment mechanism is used to adjust the angle between the main axis of the fan body and the drive shaft; the adjustment mechanism includes a support seat and a connecting seat, the support seat is connected to the drive shaft, the connecting seat is rotatably connected to the support seat, and a limit member is provided between the connecting seat and the support seat, which is used to fix the connecting seat after the connecting seat is rotated and adjusted.

[0009] Furthermore, the included angle between the drive shaft and the support surface is 45°, and the adjustment mechanism is used to adjust the included angle between the main shaft of the fan body and the drive shaft within a range of 0° to 45°.

[0010] Furthermore, two connecting parts extend from the support seat, and the connecting seat is rotatably connected between the two connecting parts; a limiting plate extends from one side of the connecting seat, and the bottom side of the limiting plate is provided with an arc surface, and the arc surface is provided with a plurality of limiting slots; an elastic pin is provided on one of the connecting parts, and one end of the elastic pin extends into one of the limiting slots; the elastic pin and the limiting slot form the limiting member.

[0011] Furthermore, the support seat includes a turntable, and the turntable covers the mounting surface.

[0012] Furthermore, the rotary drive mechanism also includes a gearbox, a motor, a driving gear and a driven gear; the gearbox is arranged on the inner side of the mounting surface; the driving gear and the driven gear are arranged in the gearbox and mesh with each other; the motor is arranged on the gearbox and connected to the driving gear; the drive shaft and the master and driven gears are integrally formed.

[0014] Furthermore, the base includes a cylindrical shell and a rotating seat, and the cylindrical shell is arranged on the rotating seat; a steering drive component is also connected between the cylindrical shell and the rotating seat, which is used to drive the cylindrical shell to rotate relative to the rotating seat.

[0015] Furthermore, a magnet is provided in the cylindrical shell for adsorbing the remote control.

[0016] The above one or more technical solutions of the fan with adjustable rotation range provided by the embodiment of the present invention have at least the following technical effects:

[0017] Because the drive shaft of the rotary drive mechanism forms an angle of 30° to 60° with the support surface of the base, the adjustment mechanism connects the fan body to the drive shaft. The rotary drive mechanism rotates the drive shaft, driving the fan body to achieve three-dimensional blowing. Since the support base of the adjustment mechanism is connected to the drive shaft, the connecting base is rotatably connected to the support base, and a limiter is provided between the connecting base and the support base, the connecting base is fixed after rotation and adjustment, thereby completing the adjustment of the angle between the main shaft and the drive shaft of the fan body and fixing the fan body. When the drive shaft drives the fan body to rotate, the fan body changes its rotation trajectory, which can expand or reduce the air outlet range of the fan body to meet the different blowing needs of users.

For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0033] In one embodiment of the fan with adjustable rotation range of the present invention, please refer to Figures 1 to 5 A fan with an adjustable rotation range includes a base 100, a fan body 200, and a rotation drive mechanism 300. The base 100 has a support surface 120 at its bottom and a mounting surface 110 at its top. The rotation drive mechanism 300 is disposed within the base 100. The rotation drive mechanism 300 includes a drive shaft 310 extending from the mounting surface 110, and the drive shaft 310 forms an angle of 30° to 60° with the support surface 120. An adjustment mechanism 400 is provided between the drive shaft 310 and the fan body 200 to connect the fan body 200 to the drive shaft 310. The adjustment mechanism 400 is used to adjust the angle between the main axis of the fan body 200 and the drive shaft 310. The adjustment mechanism 400 includes a support seat 410 and a connecting seat 420. The support seat 410 is connected to the drive shaft 310. The connecting seat 420 is rotatably connected to the support seat 410. A limiting member 430 is provided between the connecting seat 420 and the support seat 410 for fixing the connecting seat 420 after the connecting seat 420 is rotated and adjusted.

[0034] Specifically, because the drive shaft 310 of the rotary drive mechanism forms an angle of 30° to 60° with the support surface 120 of the base, the adjustment mechanism 400 connects the fan body 200 to the drive shaft 310, and the rotary drive mechanism 300 causes the drive shaft 310 to rotate and drive the fan body 200 to achieve three-dimensional blowing. Because the support base 410 of the adjustment mechanism is connected to the drive shaft 310, the connecting base 420 is rotatably connected to the support base 410, and a limiter 430 is provided between the connecting base 420 and the support base 410, so that the connecting base 420 is fixed after rotation adjustment, thereby completing the angle adjustment between the main shaft 210 of the fan body and the drive shaft 310 and fixing the fan body 200. When the drive shaft 310 drives the fan body 200 to rotate, the fan body 200 changes its rotation trajectory, which can expand or reduce the air outlet range of the fan body 200 to meet the different blowing needs of users.

[0035] Furthermore, the angle between the drive shaft 310 and the support surface 120 is 45°, and the adjustment mechanism 400 is used to adjust the angle between the main shaft 210 of the fan body and the drive shaft 310 within a range of 0° to 45°. Specifically, because the angle between the drive shaft and the support surface 120 is 45°, when the angle between the main shaft 210 of the fan body and the drive shaft 310 is 0°, the fan body 200 rotates around the main shaft 210, maintaining a 45° upward blowing angle. When the angle between the main shaft 210 of the fan body and the drive shaft 310 is 45°, the drive shaft 310 drives the fan body 200 to rotate so that the main shaft 210 of the fan body and the axis of the support surface 120 are in a horizontal or vertical state, achieving the maximum range of air discharge effect.

[0036] Furthermore, two connecting portions 411 extend from the support base 410, and the connecting base 420 is rotatably connected between the two connecting portions 411. A limit plate 421 extends from one side of the connecting base 420, and the bottom side of the limit plate 421 is provided with an arcuate surface, and the arcuate surface is provided with a plurality of limit slots 422. An elastic pin 412 is provided on one connecting portion 411, and one end of the elastic pin 412 extends into a limit slot 422. The elastic pin 412 and the limit slot 422 form a limit member 430. Specifically, the connecting base 420 is rotatably connected between the two connecting portions 411 of the support base to adjust the angle between the fan body 200 and the drive shaft 310. After the angle adjustment is completed, the elastic pin 412 extends into a limit slot 422 of the limit plate, completing the fixation of the connecting base 420, thereby fixing the angle between the main shaft 210 of the fan body and the drive shaft 310.

[0037] Furthermore, the support base 410 includes a turntable 413, which covers the mounting surface 110. Specifically, the turntable 413 covers the mounting surface 110, connects the drive shaft 310 of the rotary drive mechanism to the turntable 413, and protects the rotary drive mechanism 300.

[0038] Furthermore, the rotation drive mechanism 300 also includes a gearbox, a motor 320, a driving gear 330 and a driven gear 340. The gearbox is arranged on the inner side of the mounting surface 110, and the driving gear 330 and the driven gear 340 are arranged in the gearbox and mesh with each other. The motor 320 is arranged on the gearbox and connected to the driving gear 330, and the drive shaft 310 and the driven gear 340 are integrally formed. Specifically, the motor 320 drives the driving gear 330 to rotate, causing the driven gear 340 meshing with the driving gear 330 to rotate together. Because the drive shaft 310 and the driven gear 340 are integrally formed, the support base 410 connected to the drive shaft 310 and the driven gear 340 rotates, thereby enhancing the stability of the rotation of the support base 410, and thereby enhancing the stability of the rotation of the fan body 200.

[0039] Furthermore, a hanging position 121 is provided on one side of the support surface 120 for hanging on a wall or ceiling. Specifically, the flexibility of the fan is improved to meet the user's blowing needs in various directions and angles.

[0040] Furthermore, the base 100 includes a cylindrical housing 130 and a rotating base 140. The cylindrical housing 130 is mounted on the rotating base 140. A steering drive 150 is connected between the cylindrical housing 130 and the rotating base 140 to drive the cylindrical housing 130 to rotate relative to the rotating base 140. Specifically, the steering drive 150 drives the cylindrical housing 130 to rotate about the rotating base 140, causing the fan body 200 to rotate and swing around the rotating base 140, further expanding the fan's blowing range in the left and right directions.

[0041] Furthermore, a magnet is provided in the cylindrical shell 130 for adsorbing the remote control 500. Specifically, the remote control 500 can be adsorbed on the cylindrical shell 130 for easy storage and use.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
