Embodiment 1

[0053] The transmission structure of Embodiment 1 has relatively low requirements on the wear resistance of the gears, but requires the bayonet pin 11 to have a certain strength and deformation capacity.

[0054] Such as figure 2 As shown, the difference between the transmission structure according to the second embodiment of the present application and the first embodiment is that the first cylinder part 32 is integrated with the gear. Compared with the first embodiment, the technical solution of the second embodiment has fewer components, which is convenient for installation and stable in transmission. However, the technical solution of the second embodiment requires the material of the gear to have certain wear resistance.

[0055] Such as image 3 As shown, the difference between the transmission structure of Embodiment 3 of the present application and Embodiment 1 and Embodiment 2 is that the second transmission structure 40 includes a second cylinder portion 42 , a ca...

Embodiment 3

[0063] The characteristic of the transmission structure of the third embodiment is that the technical solution of the third embodiment has relatively low requirements on the wear resistance of the material of the gear and the bayonet pin 11 . But the number of parts in embodiment three is more than the technical solutions of embodiment one and embodiment two.

[0064] Such as Figure 7 to Figure 10 As shown, the difference between Embodiment 4 and Embodiment 3 of the transmission structure according to the present application lies in that the disc body part 33 and the gear are integrally structured. Compared with the third embodiment, the technical solution of the fourth embodiment has fewer parts, but the technical solution of the fourth embodiment requires the material of the gear to have certain wear resistance.

[0065] Such as Figure 11 As shown, the leaf turning fan of this embodiment includes the wind deflector wheel 100 and the transmission assembly 200 for driving ...

Abstract

A transmission assembly of a fan, a fan and a rotating blade fan provided with the same, wherein the transmission assembly comprises: a rotating shaft (10); a rotating member (20), which cooperates with the rotating shaft (10), which is driven by the rotating shaft (10) to rotate, and which is for use in connecting a wind deflector cover (100) on an outer side of a blade of the fan such that the wind deflector cover (100) is driven by the rotating shaft (10) to rotate; a first transmission structure (30) and a second transmission structure (40), wherein one of the first transmission structure (30) and the second transmission structure (40) is disposed on the rotating shaft (10) and rotates synchronously with the rotating shaft (10), while the other of the first transmission structure (30) and the second transmission structure (40) is disposed on the rotating member and rotates synchronously with the rotating member. The first transmission structure (30) may rotate with the second transmission structure (40) such that the rotating shaft (10) spurs the wind deflector cover (100) to rotate, and when the wind deflector cover (100) becomes stuck, the first transmission structure (30) and the second transmission structure (40) may slide opposite to each other so as to disconnect a transmission engagement between the rotating shaft (10) and the rotating member (20). The transmission assembly solves the problem in the existing technology where a motor is easily damaged when a wind deflector wheel of a vane fan becomes stuck.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a transmission assembly and a leaf turning fan with the same. Background technique [0002] The leaf turning fan is a commonly used small household appliance, and the leaf turning fan includes a housing, a fan, and a wind guide wheel. Wherein, the wind guide wheel is used to guide the air outlet. The wind deflector is driven by a motor to rotate slowly. The leaf turning fan in the prior art has the following problems: [0003] During the normal operation of the leaf turning fan, the user (children) may move the running wind deflector due to curiosity, physically block the rotation of the wind deflector or force the wind deflector to rotate in the opposite direction, which will cause damage to the motor. A large reverse torque will easily damage the internal structure of the motor, reduce the service life of the motor, and even cause the motor to fail to work norma...
