Description

[Technical Field]

[0001] The present application relates to the technical field of fans, and more particularly to fans capable of blowing air 360 degrees. [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 blow air in 360 degrees. Summary of the Invention [Problem to be solved by the invention]

[0004] The purpose of this application is to design a fan that can blow air in 360 degrees, which can achieve an omnidirectional airflow effect, and this structure effectively improves the drawback of a limited airflow angle that results in a poor user experience. [Means for solving the problem]

[0006] The movement limiting member may include a shaft portion and an extension portion, and the extension portion may extend outward from the shaft portion into the notch portion. The movement limiting member may be installed coaxially with the driven gear. A head bracket cover plate may be further provided, a connecting portion may be protrudingly installed on the driven gear, and the connecting portion may pass through the head bracket cover plate and connect to the head assembly.

[0010] 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.

[0011] The 360-degree fan according to the present disclosure 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 the 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 disclosure 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. As shown in the drawings, in the following embodiments of the present disclosure, the swing assembly is fixedly installed relative to the head bracket 10 or the support assembly 30. As will be understood by those skilled in the art, a second rotation assembly may be further installed between the head bracket 10 and the support assembly 30, or between the support assembly 30 and the swing assembly, to enable the swing assembly to rotate relative to the head bracket or the support assembly, for example, by driving a stepping motor, thereby achieving a more three-dimensional blowing effect and further improving the user experience.

[0012] In the embodiment of the present application, the oscillating assembly includes a motor 1, which is fixedly mounted on a motor bracket 2, which may be fixedly mounted on the head bracket 10 or the 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, and the connecting portion 41 is rotatable relative to the head bracket cover plate 6 with the support of the bearing 5.

[0013] 1 to 3, the motor bracket 2 is bowl-shaped and has a bottom plate, with the drive gear 3 and driven gear 4 both installed between the bottom plate of the motor bracket and the head bracket cover plate. A shaft hole 20 is formed in the bottom plate to allow the drive shaft of the motor 1 to pass through, 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. A blocking member 9 is further fixedly installed on the bottom plate of the motor bracket 2, and the blocking member 9 may be a protrusion as shown in FIG. 3, or may be an independent member that is fixedly installed and connected to the motor bracket 2.

[0014] As shown in FIG. 4 , the driven gear 4 is rotatably mounted on the head bracket cover plate 6. The driven gear 4 is provided with an annular groove 40, which is provided with a notch 8 of a certain length. A blocking member 9 is installed within the annular groove 40 and is rotatable relative to the driven gear 4 along the annular groove 40. A movement limiting member 7 is installed within the annular groove 40, which is coaxial with the driven gear 4 and rotatable relative to the driven gear 4. Specifically, the movement limiting member 7 includes a shaft 70 and an extension 11. The shaft 70 is installed coaxially with the driven gear 4, and the extension 11 extends from the shaft 70 into the notch 8 of the driven gear 4. The notch 8 has two side edges that can prevent the extension 11 from moving, so that the extension 11 can only rotate within the length of the notch 8, i.e., its rotation range is limited by the notch 8. When the blocking member 9 pushing the extension 11 to rotate is blocked by both sides of the notch 8, the motor reverses, causing the driven gear 4 to rotate in the opposite direction, and so on. The movement limiting member 7 of the present application is rotatable relative to the driven gear 4, and therefore interacts with the blocking member 9 fixedly mounted on the motor bracket 2, and is therefore referred to as a movement limiting member.

[0015] As shown in FIGS. 1 to 4 , a motor bracket 2 is fixedly installed, and a blocking member 9 is fixedly installed on the motor bracket 2. When the drive shaft of the motor 1 moves the drive gear 3 and the driven gear 4 to rotate together, the blocking member 9 may move relative to the driven gear 4 along the annular groove 40 of the driven gear 4. When the blocking member 9 collides with the extension 11 of the movement-limiting member 7, the extension 11 may continue to move within the notch 8 without immediately stopping the rotation of the driven gear 4, thereby moving the driven gear 4 to continue rotating the head assembly. The blocking member 9 cannot continue to rotate relative to the driven gear 4 until the extension 11 collides with the other side wall of the notch 8, at which point the driven gear 4 stops rotating, the motor rotates in the reverse direction, and the driven gear rotates in the reverse direction again to perform the next reverse oscillation cycle. Therefore, in the present application, a notch 8 is provided in the annular groove 40 of the driven gear 4, allowing the extension 11 of the movement limiting member 7 to continue moving a certain distance, so that the driven gear 4 can move the head assembly to blow air in omnidirectional directions of more than 360 degrees relative to the motor bracket, thereby further improving the user experience. The blowing angle range of more than 360 degrees is determined by the size of the angle range of the notch 8 and can be adjusted according to actual needs, making the fan of the present application more adaptable and adjustable, and able to meet higher user demands.

[0016] 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.
