Abstract
Description
Technical Field
[0001] This utility model relates to the field of fan electrical appliances, and in particular to a fan with a large-angle oscillation. Background Technology
[0002] Fans are common electrical appliances, but current fans have limited oscillation angles, typically unable to achieve 360-degree omnidirectional rotation. This limits the airflow range, requiring users to manually adjust the fan's position during use. Secondly, the tilt angle adjustment of the fan head is also limited. Generally, the tilt angle is small, failing to meet users' diverse needs for airflow direction in different scenarios. Furthermore, existing fan oscillation structures are usually large and bulky. This large oscillation structure not only increases the overall weight of the fan but also occupies more space, making the fan inconvenient to move and store.
[0003] In view of the shortcomings of existing technologies, it is necessary to propose new technical solutions. Utility Model Content
[0004] This invention provides a fan with a large-angle oscillation, which aims to at least solve one of the technical problems existing in the prior art.
[0005] The technical solution of this utility model is a fan with a large-angle oscillation, which includes: a fan body, the fan body including a fan head, a mounting base mechanism connected to the fan head, and an oscillation mechanism hinged to the mounting base mechanism. The oscillation mechanism includes an oscillation housing, a drive motor, a first mounting housing, and a rotating rod that is disposed in the first mounting housing and rotates relative to its central axis. The main body of the drive motor is disposed at the top of the rotating rod. The drive motor is eccentrically provided with a transmission shaft, and the transmission shaft is connected to a first gear. A second gear is provided on the inner wall of the first mounting housing. The first gear meshes with the second gear to allow the drive motor to drive the fan body to rotate relative to the central axis of the rotating rod in the first mounting housing.
[0006] Furthermore, multiple bearings are spaced apart on the rotating rod, the outer ring of the bearing is connected to the inner ring of the first mounting housing, the first gear is arranged adjacent to one of the bearings, and the central axis of the first gear and the central axis of the bearing are aligned in the same direction.
[0007] Furthermore, the first mounting housing has a limiting part that matches the outer contour shape of the bearing, there is a gap between the outer ring of the main body of the rotating rod and the inner ring of the first mounting housing, and the rotating rod has multiple reinforcing ribs spaced apart in the vertical direction.
[0008] Furthermore, the mounting mechanism includes a first mounting member fixedly connected to the fan head, a second mounting member disposed on the top of the oscillating housing, and a damping member, wherein the first mounting member is hinged to the second mounting member via a pin passing through the damping member, so as to allow the fan head to rotate from 0 to 180 degrees around the second mounting member via the first mounting member along the pitch angle.
[0009] Furthermore, the side edge of the second mounting component is fixedly connected to the vertical direction of the swaying housing by a plurality of bolts at intervals.
[0010] Furthermore, the fan head has an installation port, and a fixing plate is fixedly connected to the installation port facing inward, and the end of the first mounting member extends towards the fixing plate.
[0011] Furthermore, the swaying mechanism includes a second mounting housing that covers and is fixedly connected to the first mounting housing. A support rod is connected to the bottom end of the second mounting housing, and a power interface is provided with the bottom end of the second mounting housing facing downwards.
[0012] Furthermore, both the first and second mounting components are made of metal.
[0013] The beneficial effects of this utility model include:
[0014] This large-angle oscillating fan uses an oscillating mechanism to drive a motor that engages a first gear with a second gear, causing the fan head to rotate 360 degrees. This achieves a large-angle oscillation function for the fan body, breaking the limitations of the limited oscillation angle of traditional fans. It can deliver air over a wider range, improving the user experience and enabling the fan to better meet the air delivery needs of different scenarios. Combined with the mounting base mechanism and hinged connection to the oscillating mechanism, the fan head can also be adjusted for pitch, achieving a combination of pitch and 360-degree rotation. The oscillating mechanism is located at the bottom of the fan body, replacing the large oscillation structure that is currently attached to the back of the fan head.

[0024] Reference Figures 1 to 4 As shown, this utility model discloses a fan with a large-angle oscillation, which includes:
[0025] Reference Figures 1 to 3 The fan body 100 shown includes a fan head 110 and a mounting base mechanism 200 connected to the fan head 110. The fan head 110 is the main air supply component of the fan, and it has a motor and fan blades inside to generate airflow.
[0026] A swaying mechanism 300 is hinged to the mounting base mechanism 200. The swaying mechanism 300 includes a swaying housing 310, a drive motor 320, a first mounting housing 330, and a rotating rod 340 that rotates relative to the central axis of the first mounting housing 330. The drive motor 320 is the power source of the swaying mechanism 300. The main body of the drive motor 320 is located at the top of the rotating rod 340. The drive motor 320 is eccentrically mounted with a transmission shaft, which is connected to a first gear 321. A second gear 331 is provided on the inner wall of the first mounting housing 330.
[0027] When the drive motor 320 is working, it drives the first gear 321 to rotate through the transmission shaft, and in conjunction with... Figure 4 As shown, the first gear 321 meshes with the second gear 331, allowing the drive motor 320 to drive the fan body 100 to rotate relative to the central axis of the rotating rod 340 in the first mounting housing 330, thereby enabling the fan head to oscillate.
[0028] The oscillating mechanism drives the motor to engage the first gear with the second gear, causing the fan head to rotate 360 degrees. This achieves a large-angle oscillation function for the fan body, breaking the limitation of the traditional limited oscillation angle. It can achieve a wider range of air delivery, improve the user experience, and enable the fan to better meet the air delivery needs in different scenarios. Combined with the hinged connection of the mounting base mechanism, the oscillation mechanism also allows the fan head to adjust its pitch angle, achieving a combination of pitch angle and 360-degree rotation.
[0029] Reference Figure 2 As shown, multiple bearings 341 are spaced apart on the rotating rod 340. The outer ring of each bearing 341 is connected to the inner ring of the first mounting housing 330. The rotating rod, assembled with multiple bearings, ensures smooth rotation and axial stability within the first mounting housing. The first gear 321 is arranged adjacent to one of the bearings 341, and the central axis of the first gear 321 and the central axis of the bearing 341 run in the same direction, ensuring stable vertical rotation of the drive motor and the bearing.
[0030] Continue to refer to Figure 2 As shown, the first mounting housing 330 has a limiting portion 332 that matches the outer contour shape of the bearing 341, used to limit the bearing 341 and prevent it from shifting during rotation. A gap 339 exists between the outer ring of the main body of the rotating rod 340 and the inner ring of the first mounting housing 330, which reduces friction during rotation and improves rotation efficiency. The rotating rod 340 has multiple reinforcing ribs 342 spaced vertically to enhance its structural strength, enabling it to withstand greater forces and torques.
[0031] Reference Figures 2 to 4 As shown, the mounting mechanism 200 includes a first mounting member 210 fixedly connected to the fan head 110, a second mounting member 220 disposed on the top of the oscillating housing 310, and a damping member 230. The first mounting member 210 is hinged to the second mounting member 220 via a pin 211 passing through the damping member 230. This structure allows the fan head 110 to rotate from 0 to 180 degrees around the second mounting member 220 via the first mounting member 210, thereby achieving a wide range of adjustment of the fan head's pitch angle and meeting the diverse needs of users for airflow direction in different scenarios.
[0032] Reference Figure 4 As shown, the side edge of the second mounting component 220 is fixedly connected to the vertical direction of the oscillating housing 310 by a plurality of bolts 221 at intervals, which can ensure a stable connection between the oscillating mechanism 300 and the mounting base mechanism 200 and effectively bear the large weight of the fan head.
[0033] Reference Figure 3 As shown, the fan head 110 has an installation port, and a fixing plate 111 is fixedly connected to the installation port facing inward. The end of the first mounting member 210 extends towards the fixing plate 111, which allows the first mounting member to be fixedly connected closer to the center of gravity inside the fan head, effectively reducing the load-bearing capacity of the first mounting member.
[0034] Reference Figure 2 As shown, the oscillating mechanism 300 includes a second mounting housing 350 that covers and is fixedly connected to the first mounting housing 330. A support rod is connected to the bottom end of the second mounting housing 350 to support the entire oscillating mechanism 300. A power interface 351 is provided with a downward-facing opening at the bottom end of the second mounting housing 350, allowing the power cord port to be connected to the vertically arranged power interface 351, effectively preventing the horizontal power port from being blocked by the wall.
[0035] In some embodiments, the first mounting member 210 and the second mounting member 220 are both made of metal. Metal has high strength and stability, which can ensure the structural strength and service life of the mounting base mechanism 200, and can also withstand large forces and torques, ensuring the stable connection of the fan head 110 and the flexible adjustment of the pitch angle.
[0036] The above description is merely a preferred embodiment of this utility model. This utility model is not limited to the above-described embodiments. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this disclosure, as long as they achieve the same technical effect, should be included within the scope of protection of this disclosure and fall under the protection scope of this utility model. Within the protection scope of this utility model, the technical solutions and / or implementation methods can have various modifications and variations.
