Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0032] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0033] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0034] To address the technical problems of easy breakage and short lifespan of existing oscillating devices during the oscillation process, this utility model provides a reliable oscillating device and a circulating fan, which can effectively prevent the oscillating device from breaking and being damaged during the oscillation process, and improve the lifespan of the oscillating device.

[0035] Figures 1-8 This utility model provides a reliable head-swinging device, which includes a driving device 10, a mounting bracket 20, and a swing seat 30. The specific structure is described below:

[0036] The mounting bracket 20 is used to mount the drive device 10 and the swing seat 30. The swing seat 30 is used to mount the head assembly 40 of the fan. The swing seat 30 is rotatably mounted on the mounting bracket 20. The swing seat 30 can rotate on the mounting bracket 20, and at the same time drive the head assembly 40 of the fan to rotate, thereby realizing the oscillation.

[0037] Furthermore, a pin 31 is provided on one side of the swing seat 30, and a reinforcing member 32 is embedded in the pin 31; the driving device 10 is connected to the pin 31 and is used to drive the swing seat 30 to rotate on the mounting bracket 20.

[0038] By embedding a reinforcing member 32 inside the pin 31, the strength of the pin 31 can be greatly improved, thereby effectively preventing the pin 31 from being broken by the drive device 10 during rotation.

[0039] In this embodiment of the present invention, the reliable oscillating device includes a driving device 10, a mounting bracket 20, and an oscillating seat 30. A pin 31 is provided on one side of the oscillating seat 30, and a reinforcing member 32 is embedded within the pin 31. The oscillating seat 30 is rotatably mounted on the mounting bracket 20. The driving device 10 is connected to the pin 31 and is used to drive the oscillating seat 30 to rotate on the mounting bracket 20. The oscillating seat 30 is used to mount the head assembly 40 of the fan. It is evident that by embedding the reinforcing member 32 within the pin 31, the strength of the pin 31 can be greatly improved, effectively preventing the pin 31 from breaking during rotation by the driving device 10, thereby effectively improving the lifespan of the oscillating device. Furthermore, only the strength of the pin 31 is reinforced; there is no need to replace the entire oscillating seat 30 with a high-strength material, thus reducing costs.

[0040] To improve the ease of installation and removal of the reinforcing member 32, in some embodiments, such as this embodiment, the pin 31 is provided with an axially oriented mounting hole 33, and the reinforcing member 32 is detachably embedded in the mounting hole 33. Specifically, the reinforcing member 32 is detachably installed in the mounting hole 33 of the pin 31, which facilitates the removal and replacement of the reinforcing member 32 to achieve different degrees of strength reinforcement.

[0041] For example, the mounting hole 33 is a screw hole, the reinforcing member 32 is a screw, and the screw can be detachably screwed into the screw hole.

[0042] Furthermore, the reinforcing member 32 is made of metal, such as carbon steel, stainless steel, or copper; however, this invention does not specifically limit the material. Metal materials have high strength, thereby greatly improving the strength of the pin 31 and effectively preventing the pin 31 from breaking during rotation due to the drive device 10.

[0043] Furthermore, in some embodiments, such as this embodiment, the drive device 10 includes a motor 11, a crank 12, and a connecting rod 13. The motor 11 is connected to the crank 12, and the crank 12 is connected to the connecting rod 13. The connecting rod 13 includes a limiting hole 131, and the pin 31 and the reinforcing member 32 pass through the limiting hole 131.

[0044] Specifically, the output shaft of the motor 11 is embedded in the crank 12 and fixedly connected to the crank 12 by fasteners; the crank 12 is connected to one end of the connecting rod 13 by fasteners, and the other end of the connecting rod 13 is provided with a limiting hole 131, and the pin 31 and the reinforcing member 32 pass through the limiting hole 131.

[0045] The power of the motor 11 is transmitted to the pin 31 through the crank 12 and the connecting rod 13 in sequence, which drives the pin 31 to rotate, thereby driving the swing seat 30 to rotate.

[0046] To improve the stability of the rotation of the swing seat 30, in some embodiments, such as this one, the mounting bracket 20 is provided with a guide hole 21, through which the pin 31 and the reinforcing member 32 pass and can rotate within the guide hole 21.

[0047] Specifically, the guide hole 21 is arc-shaped, matching the swing trajectory of the swing seat 30. The guide hole 21 can guide the rotation of the pin 31, thereby improving the stability of the swing seat 30's rotation.

[0048] Furthermore, the mounting bracket 20 includes a rotating shaft 22, and the swing seat 30 includes a shaft hole 34, with the rotating shaft 22 passing through the shaft hole 34.

[0049] Specifically, the swing seat 30 rotates around the pivot 22, which effectively improves the stability of the swing seat 30's rotation.

[0050] Furthermore, the reliable oscillating head device also includes a bearing 50, which is disposed between the rotating shaft 22 and the inner wall of the shaft hole 34.

[0051] The bearing 50 is sleeved on the rotating shaft 22 and located between the rotating shaft 22 and the inner wall of the shaft hole 34. By setting the bearing 50, the smoothness of the rotation of the swing seat 30 can be improved and the jamming during the rotation process can be avoided.

[0052] Furthermore, the end of the rotating shaft 22 is provided with a first bearing retaining ring 60 and a second bearing retaining ring 70; the first bearing retaining ring 60 covers the outer side of the end face of the bearing 50 and is connected to the swing seat 30; the second bearing retaining ring 70 covers the inner side of the end face of the bearing 50 and is connected to the rotating shaft 22. The first bearing retaining ring 60 and the second bearing retaining ring 70 can effectively prevent the swing seat 30 and the bearing 50 from detaching from the rotating shaft 22.

[0053] Furthermore, in some embodiments, such as this one, the motor 11 is mounted on the mounting bracket 20 by fasteners.

[0054] Specifically, the housing of the motor 11 is provided with mounting ears, which are fixed to the mounting bracket 20 by screws.
