Description

[Technical Field]

[0001] The present application relates to the technical field of fans, and more particularly to fans capable of blowing air in all directions. [Background technology]

[0002] In the prior application, the applicant of Application No. 2024227664683 provided a direction-changing oscillating fan, in which a stopper and a limiting member are fixedly installed on the base and the driven gear, respectively, so that when the driven gear rotates to a certain angle, the stopper on the driven gear collides with the limiting member on the base, causing a force to be applied to the drive gear and the motor shaft, causing the motor shaft to move in the opposite direction, and this reciprocating motion is repeated to achieve constantly changing direction and oscillation. In this structural design, because the stopper and limiting member are fixedly installed on the base and the driven gear, respectively, the fan cannot rotate 360 degrees, and therefore cannot achieve an omnidirectional airflow effect, resulting in a poor user experience.

[0003] Therefore, there is a need in the prior art for a fan that can achieve omnidirectional airflow. Summary of the Invention [Problem to be solved by the invention]

[0011] In order to clarify the objectives, technical solutions and advantages of the present application, the following detailed description of the embodiments of the present application is given with reference to the accompanying drawings. It should be noted that, unless contradictory, the embodiments and features of the embodiments of the present application may be arbitrarily combined with each other.

[0012] The omnidirectional fan according to the present application includes a head assembly 50, to which a swing assembly is connected. The head assembly 50 is connected to a head bracket 10 via the swing assembly, and the head bracket 10 is connected to a support assembly 30. Alternatively, the head assembly 50 is directly connected to the support assembly 30 via the swing assembly. The swing assembly according to the present application enables the head assembly to swing back and forth. Preferably, a head bracket cover plate 6 is further provided between the swing assembly and the head assembly 50. In the following embodiments of the present application, the swing assembly is fixedly installed relative to the head bracket 10 or the support assembly 30.

[0013] As shown in FIGS. 1 to 6 , the oscillating assembly includes a motor 1, which is fixedly mounted on a motor bracket 2, which may be fixedly mounted on a head bracket 10 or a support column assembly 30. The oscillating assembly further includes a drive gear 3 and a driven gear 4 that mesh with each other, with the motor 1 connected to the drive gear 3 to drive and rotate the drive gear 3, which in turn moves the driven gear 4 to rotate. A connecting portion 41 protrudes from the top of the driven gear 4, and the connecting portion 41 passes through the head bracket cover plate 6 and is fixedly connected to the head assembly 50, so that when the driven gear 4 rotates, the head assembly 50 can be moved to rotate together. A bearing 5 is provided between the connecting portion 41 of the driven gear 4 and the head bracket cover plate 6, so that the connecting portion 41 is rotatable relative to the head bracket cover plate 6.

[0014] As shown in FIGS. 1 to 6 , the motor bracket 2 is bowl-shaped and includes a bottom plate. The drive gear 3 and driven gear 4 are both installed between the bottom plate of the motor bracket and the head bracket cover plate 6. The bottom plate is provided with a shaft hole 20 through which the drive shaft of the motor 1 passes. The motor bracket 2 is fixedly connected to the lower structure by a plurality of fixing portions 21, and the drive gear 3 is fixedly connected to the drive shaft of the motor 1. An opening 12 is further provided in the bottom plate of the motor bracket 2, and the opening 12 is installed to a certain length so as to have an arc shape. A movement-blocking assembly is installed within the opening 12. The movement-blocking assembly includes a blocking portion 7 and an end portion 77, which are fixedly connected to the blocking portion 7 in a releasable manner. The blocking portion 7 is installed within the opening 12 of the motor bracket 2 and is slidable back and forth along the arc-shaped opening 12. The opening length of the opening 12 can be set according to the need for the fan to rotate within a range exceeding 360 degrees. A mutually engaging coupling may be provided on the contact surfaces of the blocking portion 7 and the opening 12, for example, a groove and a protrusion may be mutually engaged to realize a slidable installation of the blocking portion 7 within the opening 12, thereby maintaining the blocking portion 7 inserted into the opening 12 by a fixed length and preventing it from moving up and down.

[0015] 4, the driven gear 4 is rotatably installed relative to the head bracket cover plate 6, the driven gear 4 is provided with an annular groove 40, and the blocking portion 7 of the movement blocking assembly extends into the annular groove 40 and is rotatable relative to the annular groove 40. A pushing portion 11 is fixedly installed in the annular groove 40, and the pushing portion 11 may be fixedly installed between the inside and outside of the annular groove 40. When the pushing portion 11 of the driven gear 4 is effectively blocked by the blocking portion 7, the driven gear 4 stops, but the motor rotates in the reverse direction, causing the driven gear 4 to rotate in the reverse direction.

[0016] In the present application, a motor bracket 2 is fixedly installed, and a certain length of opening 12 is provided in the motor bracket 2, and a movement preventing assembly is provided within the opening 12 so as to be slidable along the opening 12. When the drive shaft of the motor 1 moves the drive gear 3 and the driven gear 4 to rotate together in a certain direction, and the pushing portion 11 of the driven gear 4 collides with the blocking portion 7 of the movement preventing assembly, the rotation of the driven gear 4 is not immediately stopped but is allowed to continue moving within the opening 12 by the blocking portion 7, thereby allowing the driven gear 4 to continue rotating until the blocking portion 7 collides with the other side wall of the opening 12, whereby the driven gear 4 is effectively blocked and cannot continue to rotate relative to the blocking portion 7, further causing the motor to rotate in the reverse direction. Therefore, in the present application, the opening 12 is fixedly installed on the motor bracket 2, and a blocking part 7 is provided along the opening 12, which can slide a certain distance, thereby effectively blocking the pushing part of the driven gear 4 from rotating 360 degrees or more before reversing the motor, thereby realizing omnidirectional airflow of 360 degrees or more and further improving the user experience. The airflow angle range of 360 degrees or more is determined by the size of the opening 12 and can be adjusted according to actual needs, making the fan of the present application more adaptable and able to meet higher user demands.

[0017] The above are the embodiments disclosed in the present application, but the above contents are merely used to facilitate understanding of the present application and are not intended to limit the present application. Those skilled in the art may make any modifications and changes to the embodiments and details without departing from the spirit and scope disclosed in the present application, but the patent protection scope of the present application should still comply with the scope defined in the appended claims.
