[0002] Fans can be used to cool down and circulate air. They are very commonly used electrical appliances. In order to obtain a wider air supply range, fans often have a shaking head function, which changes the air supply direction by driving the fan head to rotate, and then widens the air supply range by repeatedly shaking the head.

[0003] In the related art, most fan shaking structures adopt four-link structure or gear transmission structure. The four-link shaking structure often needs multiple parts such as crank and connecting rod, and the connection between parts needs screws to fix. The assembly is complicated, with many parts, time-consuming and labor-intensive. The gear transmission structure also requires at least two gears for assembly. There must be a good gap between the gears, otherwise there will be problems such as shaking of the head stuck or abnormal noise of gear movement, and the processing and assembly requirements are high.

[0038] See also Figures 1 to 3The oscillating structure 100 provided in one embodiment of the present application includes a bracket 10, a base 30 and an oscillating motor 50. The base 30 is rotatably connected to the bracket 10 around a rotation axis. The oscillating motor 50 is disposed on the bracket 10, and its output shaft 51 is disposed along the rotation axis and is fixedly engaged with the base 30.

[0039] In one embodiment, the shaking head structure 100 is used for a fan, and one of the bracket 10 and the base 30 is used to connect to the fan head, and the other of the bracket 10 and the base 30 is connected to the fan seat, the fan column or serves as the fan seat. Specifically, the bracket 10 shell is connected to the fan head, and the base 30 can be connected to the fan seat or serve as the fan seat. In some other embodiments, the shaking head structure 100 can also be used in fresh air fans, humidifiers, heaters and other equipment that require shaking heads, which are not specifically limited here.

[0040] The bracket 10 and the base 30 can rotate relative to each other around the rotation axis. It can be understood that the rotation axis only represents the axis of rotation between the base 30 and the bracket 10, and does not really exist. The rotation axis can also be the central axis of the bracket 10 and the base 30 at the same time. The height direction of the bracket 10 and the base 30 is parallel to the rotation axis.

[0041] The oscillating head motor 50 is arranged on the bracket 10, and its body 53 is fixed relative to the bracket 10. Since the output shaft 51 of the oscillating head motor 50 can also rotate around the rotation axis, when rotating, it can generate a set of torques on the bracket 10 and the base 30, and drive the bracket 10 and the base 30 to rotate relative to each other, thereby realizing the oscillating head movement of the fan.

[0042] The oscillating structure 100 has an oscillating motor 50 disposed on the bracket 10, but the output shaft 51 is in rotation-stopping cooperation with the base 30, and the bracket 10 and the base 30 are rotationally connected. Therefore, after starting, the oscillating motor 50 can drive the bracket 10 and the base 30 to rotate relative to each other, thereby realizing the oscillating movement of the fan. In this way, the oscillating structure 100 can realize the oscillating movement of the fan driven directly by the oscillating motor 50 without the need for a complex transmission mechanism, and has a simpler structure, lower processing and assembly requirements, and more stable rotation of the fan, and is less prone to abnormal noise.

[0043] Please also read Figure 4 In some embodiments, the oscillating motor 50 has a fixing ear 55 and is screwed to the bracket 10 via the fixing ear 55 .

[0044] Specifically, the fixing ear 55 is located on the body 53 of the shaking motor 50, the shaking structure 100 includes a first screw 551, the fixing ear 55 has a screw hole, the bracket 10 has a first threaded hole 11, the first screw 551 passes through the fixing ear 55 and cooperates with the first threaded hole 11, thereby fixing the fixing ear 55 on the bracket 10.

[0045] In this way, the oscillating motor 50 is stably connected to the bracket 10, and after the oscillating motor 50 is started, the bracket 10 connected to the oscillating motor 50 and the base 30 that is locked with the output shaft 51 can rotate relatively stably.

[0046] Please also read Figure 5 and Figure 6 In some embodiments, the bracket 10 has an installation cavity 12 for accommodating the oscillating motor 50 and a through hole 13 connected to the installation cavity 12. The base 30 is at least partially rotatably arranged in the through hole 13 to form a rotational connection around the rotation axis, and is anti-rotationally engaged with the output shaft 51 of the oscillating motor 50 located in the installation cavity 12 through the through hole 13.

[0047] It can be understood that the portion of the base 30 that passes through the through hole 13 can rotate around the rotation axis in the through hole 13. The hole axis of the through hole 13 can coincide with the rotation axis.

[0048] In this way, the oscillating motor 50 can be stably installed in the installation cavity 12 , and the base 30 can also form a stable rotation connection with the bracket 10 by means of the through hole 13 and cooperate with the oscillating motor 50 .

[0049] Please also read Figure 7 and Figure 8 In some embodiments, the base 30 includes a rotating shaft 31 and a seat body 33. The first end 311 of the rotating shaft 31 in its own axial direction is located outside the end of the through hole 13 close to the mounting cavity 12, and is configured to be unable to pass through the through hole 13 and to cooperate with the output shaft 51 of the shaking motor 50 to stop rotation. The second end 313 of the rotating shaft 31 in its own axial direction is fixedly connected to the seat body 33, and the seat body 33 is at least partially configured to be unable to pass through the through hole 13.

[0050] The axis of the rotating shaft 31 coincides with the rotating shaft, and its axial direction is consistent with the axial direction of the rotating shaft. During assembly, the rotating shaft 31 can be installed from the mounting cavity 12, and the first end 311 of the rotating shaft 31 is stuck outside the through hole 13, and the seat body 33 can be connected to the rotating shaft 31 from the other end, and at least part of it is also stuck outside the through hole 13. For example, the first end 311 of the rotating shaft 31, the through hole 13, and the cross section of the seat body 33 perpendicular to the rotating shaft are all circular, and the diameter of the first end 311 of the rotating shaft 31 and the diameter of at least part of the seat body 33 are greater than the diameter of the through hole 13.

[0051] Specifically, the second end 313 of the rotating shaft 31 is inserted into the through hole 13. During assembly, the rotating shaft 31 is inserted into the mounting cavity 12, and the second end 313 thereof is aligned and inserted into the through hole 13, and the seat body 33 is fixedly connected to the seat body 33 from the other end of the bracket 10. Due to the obstruction of the first end 311 and the seat body 33, the rotating shaft 31 cannot pass through the through hole 13 and escape from the bracket 10.

[0052] In this way, the base 30 cooperates with the shaking motor 50 to stop rotation through its rotating shaft 31, and the first end 311 of the rotating shaft 31 and the base body 33 are stuck outside the through hole 13, which can reduce the probability of separation of the base 30 and the bracket 10, and improve the stability of the connection between the two while maintaining the ability of the two to rotate relative to each other.

[0053] Furthermore, the bracket 10 further comprises an accommodating cavity 14 between the mounting cavity 12 and the through hole 13, the accommodating cavity 14 communicates with the mounting cavity 12 and the through hole 13, the first end 311 of the rotating shaft 31 is located in the accommodating cavity 14, and the second end 313 is located in the through hole 13. The seat body 33 has a rotating head 331 at one end in the direction of the rotating shaft, the rotating head 331 is inserted into the through hole 13, and the parts of the seat body 33 other than the rotating head 331 cannot enter the through hole 13. The rotating head 331 has a counterbore 3311 extending in the direction of the rotating shaft, the second end 313 of the rotating shaft 31 is inserted into the counterbore 3311, and the two are matched in the through hole 13.

[0054] Furthermore, the second end 313 of the rotating shaft 31 is fixedly connected to the seat body 33 by means of screws.

[0055] Specifically, the shaking head structure 100 also includes a second screw 35, the base body 33 has a screw hole connected to the countersunk hole 3311, the second end 313 of the rotating shaft 31 has a second threaded hole 3131, and the second screw 35 is arranged along the direction of the rotating shaft, passes through the screw hole and cooperates with the second threaded hole 3131 of the second end 313, so as to fix the base body 33 and the second end 313 of the rotating shaft 31.

[0056] In this way, the second end 313 of the rotating shaft 31 and the seat body 33 can form a stable connection, and the screw connection method is easy to assemble and disassemble.

[0057] In some embodiments, the output shaft 51 of the oscillating motor 50 is configured with a first stop level 511 , the first end 311 of the rotating shaft 31 has an axial hole 3111 , and the axial hole 3111 is configured with a first mating level 3113 mating with the first stop level 511 .

[0058] In this way, the output shaft 51 of the oscillating motor 50 can be inserted into the shaft hole 3111 of the rotating shaft 31 to form a non-rotating fit therewith, and the connection method is simple.

[0059] In some embodiments, the second end 313 of the rotating shaft 31 is configured with a second anti-rotation level 3133 , and the seat body 33 has a counterbore 3311 for accommodating the second end 313 , and the counterbore 3311 is configured with a second mating level 3313 mating with the second anti-rotation level 3133 .

[0060] The second end 313 of the rotating shaft 31 is inserted into the counterbore 3311 . The counterbore 3311 extends along the direction of the rotating shaft and is specifically formed at the rotating head 331 of the base 33 .

[0061] In this way, after the second end 313 of the rotating shaft 31 is inserted into the counterbore 3311 , it is convenient for the seat body 33 to form a rotation-stopping fit and can rotate synchronously with the seat body 33 .

[0062] In some embodiments, one of the base 30 and the bracket 10 has a stop rib 37, and the other has two stop structures 15, and the stop rib 37 is configured to rotate around the rotation axis between the two stop structures 15. There may be one stop rib 37 or two stop ribs 37 that are arranged opposite to each other.

[0063] Taking the base 30 having a stop rib 37 and the bracket 10 having two stop structures 15 as an example, the stop rib 37 is configured to be able to rotate around the rotation axis between the two stop structures 15 along with the base 30. Specifically, the stop rib 37 is constructed on the rotation axis 31, and the stop structure 15 is constructed on the cavity wall of the accommodating cavity 14.

[0064] In other words, the stop rib 37 is restricted to rotate between the two stop structures 15 . Therefore, the rotation angle between the bracket 10 and the base 30 is also restricted by the stop rib 37 and the stop structure 15 .

[0065] In this way, the stop rib 37 and the stop structure 15 can limit the rotation range of the bracket 10 and the base 30, thereby limiting the swing amplitude of the fan.

[0066] Please also read Fig. 9 In some embodiments, the shaking head structure 100 further includes a support base 70 , which is supported between the bracket 10 and the base 30 and can rotate around a rotation axis relative to at least one of the bracket 10 and the base 30 .

[0067] In this way, the support base 70 can enhance the stability of the connection between the bracket 10 and the base 30 . At the same time, since the support base 70 can rotate relative to at least one of the bracket 10 and the base 30 , the relative rotation between the bracket 10 and the base 30 is not restricted.

[0068] Further, in a direction parallel to the rotation axis, the area of ​​the end of the base 30 away from the bracket 10 is larger than the area of ​​the end close to the bracket 10, and the end of the base 30 away from the bracket 10 has a support surface 333 facing the bracket 10. One end of the support seat 70 is supported on the end of the bracket 10 close to the base 30, and the other end is supported on the support surface 333 of the base 30.

[0069] Similarly, the area of ​​the end of the base 30 away from the connection between the bracket 10 and the base 30 is larger than the area of ​​the end close to the connection between the bracket 10 and the base 30, so that the base 30 can obtain sufficient bottom area without taking up too much space.

[0070] In this way, the support seat 70 can provide stable support for the bracket 10. At the same time, compared with directly expanding the area of ​​the end of the bracket 10, the manufacturing and demolding of the parts are less difficult, and other structures can be installed in the empty space between the bracket 10 and the support seat 70.

[0071] Furthermore, in a direction parallel to the rotation axis, one end of the support seat 70 is fixedly connected to the bracket 10 , and the other end is slidably supported on the support surface 333 .

[0072] The end of the bracket 10 near the base 30 has a connecting platform, one end of the support seat 70 is sleeved on the connecting platform and has a fixing screw hole 71, and the bracket 10 is provided with a corresponding third threaded hole 16. The shaking head structure 100 also includes a third screw 75, and the support seat 70 is fixedly connected to the bracket 10 through the third screw 75. In addition, the support seat 70 may have a positioning bayonet 73, and is positioned with the bracket 10 through the positioning bayonet 73. The support seat 70 slides relative to the supporting surface 333 to achieve its rotation around the rotation axis relative to the base 30.

[0073] In this way, the support seat 70 can stably connect and support the bracket 10, and provide sliding support through the support surface 333 with a larger area.

[0074] The assembly steps of the above-mentioned oscillating structure 100 may be as follows: 1. Insert the rotating shaft 31 from the installation cavity 12, and insert the second end 313 thereof into the through hole 13, and the first end 311 is accommodated in the accommodating cavity 14. 2. Align the screw hole of the fixing ear 55 of the oscillating motor 50 with the first threaded hole 11 of the bracket 10, and fix the oscillating motor 50 on the bracket 10 by the first screw 551. 3. Align the fixing screw hole 71 of the support seat 70 with the corresponding third threaded hole 16 on the bracket 10, and connect them by the third screw 75. 4. Insert the rotating head 331 of the seat body 33 into the through hole 13, and align its counterbore 3311 with the second end 313 of the rotating shaft 31, and accommodate the rotating shaft 31. Pass the second screw 35 through the screw hole of the seat body 33, and screw it into the second threaded hole 3131 of the second end 313 of the rotating shaft 31, and fix the seat body 33 to the rotating shaft 31. It can be understood that the above steps can be adaptively adjusted in sequence and are not specifically limited here.

[0075] Thus, the oscillating structure 100 has a simple structure and is easy to assemble, and can directly drive the base 30 and the bracket 10 to rotate relative to each other through the oscillating motor 50. The relative rotation of the base 30 and the bracket 10 is supported by the support seat 70, and the rotation range is limited by the stop rib 37 and the stop structure 15, so as to stably realize the oscillating motion of the fan.

[0076] The present application also provides a fan, comprising the above-mentioned shaking head structure.

[0077] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
