[0041] A fan is a household appliance that uses an electric motor to drive the blades to rotate to accelerate the flow of air. It is mainly used for cooling and circulating air. In order to expand the air supply effect of the fan and enhance the heat dissipation effect, the fan is usually provided with a shaking head mechanism. In the prior art, the shaking head mechanism of the fan usually adopts a combination of a motor and a gear or a four-bar linkage to achieve the shaking head effect. The shortcomings are: the combination of the motor and the gear takes up a large space, which makes the fan larger. In addition, when the processing and assembly accuracy of the gears are insufficient, noise, vibration and other problems are likely to occur, affecting the user's experience; the overall structure of the four-bar linkage is relatively complex, and the transmission efficiency is low. If the assembly error of the connecting rod is large, the shaking head effect is unstable, and it is easy to cause problems such as jamming and abnormal noise, affecting the normal use of the user.

[0042] In view of the above problems, this application provides a fan shaking mechanism, please refer to Figure 1-Figure 6 ,include:

[0043] A rotating assembly 1, the rotating assembly 1 comprising a rotating member 11, a fastener 12 fixedly connected to the lower portion of the rotating member 11, and a driving member 13 fixed inside the rotating member 11;

[0044] A fixing assembly 2, the fixing assembly 2 comprising a first fixing member 21 and a second fixing member 22 fixedly connected to the first fixing member 21, wherein the second fixing member 22 is disposed above the first fixing member 21, and the first fixing member 21 is fixedly connected to an output portion of the driving member 13;

[0045] The fastener 12 is located between the first fixing member 21 and the second fixing member 22 to limit the rotating member 11 on the fixing assembly 2. The rotating member 11 is sleeved on the second fixing member 22 and rotates relative to the fixing assembly 2 under the drive of the driving member 13. In the fan shaking mechanism provided in the present application, the rotating member 11 is sleeved and limited on the fixing assembly 2 by the fastener 12, the driving member 13 is fixed inside the rotating member 11, and the output part of the driving member 13 is connected to the fixing assembly 2. The relative rotation of the rotating assembly 1 and the fixing assembly 2 is realized by the drive of the driving member 13, thereby realizing the function of driving the fan to shake its head. The overall structure is simple, which improves the problem of poor use effect of the fan shaking mechanism in the prior art. In addition, the overall installation structure is compact, which reduces the volume of the fan and is convenient for users to carry.

[0046] For further information, see Figure 1-Figure 4 A spacer plate 221 is provided in the hollow portion of the second fixing member 22 , and a first bearing 23 is provided on one side of the spacer plate 221 . The outer ring of the first bearing 23 cooperates with the inner wall of the second fixing member 22 , and the peripheral side of the rotating member 11 cooperates with the inner ring of the first bearing 23 .

[0047] In the present application, the second fixing member 22 includes a first component 222 and a second component 223 located on the outer peripheral side of the first component 222. The first component 222 and the second component 223 are an integrally formed structure. The first component 222 is a hollow cylinder, and the second component 223 is an annular structure. The cross section of the second component 223 is L-shaped. The horizontal portion of the second component 223 is connected to the outer side wall of the first component 222, and the horizontal portion of the second component 223 is higher than the lower end surface of the first component 222. The inner wall of the first component 222 extends toward the center to form a circular ring-shaped spacer plate 221. The inner diameter of the spacer plate 221 is smaller than the inner ring diameter of the first bearing 23 to avoid friction between the rotating member 11 and the spacer plate 221 when the rotating member 11 rotates relative to the second fixing member 22, and friction between the inner ring end surface of the first bearing 23 and the end surface of the spacer plate 221. The spacer plate 221 is arranged to tighten in the axial direction. The fastener 12 plays a limiting role, so that the fastener 12 is located between the first fixing member 21 and the second fixing member 22, and then the rotating member 11 is limited to the fixed component 2, ensuring that when the rotating member 11 is sleeved on the second fixing member 22, the rotating member 11 can stably rotate relative to the second fixing member 22 under the drive of the driving member 13; in order to reduce the friction generated during the rotation process, the side of the fastener 12 does not contact the fixed component 2; the setting of the first bearing 23 converts the sliding friction during the relative rotation of the rotating member 11 and the second fixing member 22 into rolling friction, reducing the friction between the two, improving the smoothness of the relative rotation, and reducing the noise generated during the relative rotation; in addition, the setting of the bearing enables the driving member 13 to output a smaller driving force, which can cause the rotating member 11 and the fixed component 2 to rotate relative to each other, reducing the selection cost of the driving member 13.

[0048] In one embodiment of the present application, the first bearing 23 is located above the partition plate 221, and the lower end surface of the partition plate 221 is directly in contact with the fastener 12, thereby limiting the position of the fastener 12 in the axial direction. Since the lower portion of the rotating member 11 is connected to the fastener 12, and the fastener 12 is located between the first fixed member 21 and the second fixed member 22, the rotating member 11 is limited to the fixed component 2; in addition, the rotating member 11 is installed on the fixed component 2 through the first bearing 23, and the lower portion of the driving member 11 is in contact with the inner ring of the first bearing 23. Since the driving member 13 is fixed inside the rotating member 11, the output portion of the driving member 13 is connected to the first fixed member 21, and the fixed component 2 of the rotating member 11 rotates relatively under the driving action of the driving member 13.

[0049] In another embodiment of the present application, the first bearing 23 is located below the partition plate 221. Since the first bearing 23 is located between the partition plate 221 and the fastener 12, the partition plate 221 indirectly defines the position of the fastener 12 in the axial direction by defining the position of the first bearing 23. The upper end face of the first bearing 23 contacts the lower end face of the partition plate 221, and the lower end face of the first bearing 23 contacts the end face of the fastener 12. Since the lower portion of the rotating member 11 is connected to the fastener 12, and the fastener 12 is located between the first fixed member 21 and the second fixed member 22, the rotating member 11 is defined on the fixed component 2. The output portion of the driving member 13 is connected to the first fixed member 21, and the fixed component 2 of the rotating member 11 rotates relatively under the driving action of the driving member 13.

[0050] Further, please refer again to Figure 1-Figure 6 A second bearing 24 coaxial with the first bearing 23 is disposed on the other side of the partition plate 221, the outer ring of the second bearing 24 cooperates with the inner wall of the second fixed member 22, and the circumferential side of the rotating member 11 cooperates with the inner ring of the second bearing 24. The first bearing 23 is located above the second bearing 24, the fastener 12 is located below the second bearing 24, and a first step portion 121 is disposed on the fastener 12, and the first step portion 121 contacts the end surface of the second bearing 24, so as to limit the rotating component 1 to the fixed component 2.

[0051] In another embodiment of the present application, two bearings are arranged on the second fixed member 22, the outer ring of the first bearing 23 and the outer ring of the second bearing 24 are both matched with the inner side wall of the first member 222, the inner ring of the first bearing 23 and the inner ring of the second bearing 24 are both matched with the circumference of the lower part of the rotating member 11, the first bearing 23 and the second bearing 24 are arranged at intervals on the upper and lower sides of the partition plate 221, and the arrangement of the double bearing structure can better disperse and balance the load, reduce the vibration generated when the driving member 13 is working, make the relative rotation of the rotating member 11 and the fixed component 2 more stable, and improve the overall life and safety of the rotating structure. In the present application, the first bearing 23 and the second bearing 24 are arranged coaxially, and the inner ring diameters of the first bearing 23 and the second bearing 24 are the same, so as to facilitate the installation and matching with the lower part of the rotating member 11, and the outer ring diameters of the first bearing 23 and the second bearing 24 can be the same or different.

[0052] In an embodiment of the dual-bearing structure, the lower end face of the outer ring of the first bearing 23 contacts the upper end face of the spacer plate 221, the lower end face of the spacer plate 221 contacts the upper end face of the outer ring of the second bearing 24, the end face of the first step portion 121 contacts the lower end face of the inner ring of the second bearing 24, and the spacer plate 221 limits the axial position of the fastener 12 through the second bearing 24, thereby ensuring that the rotating member 11 is stably set on the fixed component 2; the lower part of the rotating member 11 is screwed and fixed to the fastener 12, and when the rotating member 11 and the fixed component 2 rotate relative to each other, the rotating member 11 will drive the fastener 12 to rotate synchronously relative to the fixed component 2, and the end face of the first step portion 121 contacts the inner ring end face of the second bearing 24, thereby avoiding the friction generated after the fastener 12 contacts the outer ring end face of the second bearing 24 to affect the relative rotation of the rotating member 11 and the fixed component 2.

[0053] Furthermore, a second step portion 122 is provided on the fastener 12, and the second step portion 122 is located on the inner side of the first step portion 121 and is higher than the first step portion 121. The circumferential side of the second step portion 122 cooperates with the inner ring of the second bearing 24, and the end face of the second step portion 122 contacts the lower end face of the rotating member 11.

[0054] In the present application, the fastener 12 is annular, and the first step portion 121 and the second step portion 122 are annular bosses formed by the upward extension of the fastener 12. The end face of the first step portion 121 contacts the end face of the inner ring of the second bearing 24. Since the second step portion 122 is located on the inner side of the first step portion 121 and the second step portion 122 is higher than the first step portion 121, the second step portion 122 extends into the inner side of the inner ring of the second bearing 24. The height of the second step portion 122 is less than the height of the second bearing 24, so that the lower part of the rotating member 11 can also contact the inner ring of the second bearing 24, which is conducive to ensuring the synchronization of the rotating member 11 and the fastener 12 during rotation; the provision of the first step portion 121 ensures that after the rotating member 11 is fixedly connected to the fastener 12, the fastener 12 abuts against the inner ring of the second bearing 24. Due to the presence of the partition plate 221 above the second bearing 24, the position of the rotating member 11 is indirectly limited in the axial direction. , ensuring the stability of the axial installation of the rotating member 11; the setting of the second step portion 122, on the one hand, facilitates the fixed connection between the rotating member 11 and the fastener 12, and on the other hand, the circumferential side of the second step portion 122 contacts the inner ring circumferential side of the second bearing 24, ensuring the synchronization of the fastener 12 and the rotating member 11 during the relative rotation, thereby improving the rotation efficiency; the end face of the second step portion 122 contacts the lower end face of the rotating member 11, and the second step portion 122 is screwed and fixed to the lower part of the rotating member 11, and the fastener 12 is lifted to a certain height by the rotating member 11, so that there is a height difference between the lower end of the fastener 12 and the bottom surface of the first fixing member 21, and when the rotating member 11 synchronously drives the fastener 12 to rotate relative to the fixed component 2, the existence of the height difference prevents the fastener 12 from generating friction with the first fixing component 21, thereby ensuring the smoothness of the relative rotation of the rotating member 11 and the fixed component 2, while improving the service life of the fastener 12.

[0055] Further, one of the rotating member 11 and the second fixed member 22 is provided with a limiting member 111, and the other of the rotating member 11 and the second fixed member 22 is provided with a limiting groove 224. When the rotating member 11 and the second fixed member 22 are assembled, the limiting member 111 is located in the limiting groove 224 to limit the relative rotation angle of the rotating component 1 and the fixed component 2. In the embodiment of the present application, the limiting member 111 is provided on the rotating member 11, and the limiting groove 224 is provided on the second fixed member 22, and the limiting groove 224 is located between the first component 222 and the second component 223. The limiting groove 224 is an arc-shaped guiding space. After the rotating member 11 and the second fixed member 22 are installed and matched, the limiting member 111 is located in the limiting groove 224. The limiting groove 224 can play an auxiliary guiding role in the relative rotation process of the rotating member 11 and the fixed component 2, further improving the stability of the relative rotation, and can also play a limiting role to ensure the relative rotation effect of the rotating member 13 and the fixed component 2, and the structure is simple.

[0056] Furthermore, the fastener 12 is an annular structure, and a first fixing portion 123 protrudes toward the center of the inner circumference of the fastener 12. The lower part of the rotating member 11 is a hollow cylinder, and a second fixing portion 112 protrudes on the inner circumference of the lower part of the rotating member 11. Part of the end surface of the first fixing portion 123 extends upward to form a positioning portion 124 to cooperate with the circumferential side of the second fixing portion 112. In the present application, threaded holes are provided in the first fixing portion 123 and the second fixing portion 112, and a countersunk hole coaxial with the threaded hole is also provided on the first fixing portion 123. The screw extends from the bottom of the first fixing portion 123 and enters the second fixing portion 112 to screw the fastener 12 and the rotating member 11 together. The fixing connection method is simple and convenient. The end of the screw is located in the countersunk hole to avoid affecting the assembly of other components; the positioning portion 124 is arc-shaped. After the fastener 12 and the rotating member 11 are installed and matched, the positioning portion 124 cooperates with the circumferential side of the second fixing portion 112. The setting of the positioning portion 124, on the one hand, plays a guiding role, which is convenient for determining the relative position of the first fixing portion 123 and the second fixing portion 112, which is beneficial to the installation and matching of the fastener 12 and the rotating member 11. On the other hand, it plays a relative limiting role in the circumferential direction to avoid relative rotation of the fastener 12 and the rotating member 11.

[0057] Furthermore, the second fixing member 22 includes a first component 222 and a second component 223 located on the outer peripheral side of the first component 222, the lower end surface of the second component 223 extends axially to form a third fixing portion 225, the third fixing portion 225 is located on the outer side of the first component 222, the first component 222 and the third fixing portion 225 extend into the hollow portion of the first fixing member 21, and the first fixing member 21 is provided with a fourth fixing portion 211 adapted to the third fixing portion 225 and a support ring (not marked in the figure) for supporting the first component 222, thereby ensuring the stability of the assembly of the first fixing member 21 and the second fixing member 22. The third fixing portion 225 is a fixing column, and the fourth fixing portion 211 is provided with a fixing groove (not marked in the figure) for installing the third fixing portion 225, and threaded holes are provided in the fixing groove and the fixing column. The lower end surface of the second component 223 is provided with a countersunk hole coaxial with the threaded hole of the fixing groove, and the screw enters the third fixing portion 225 and the fourth fixing portion 211 from the lower end surface of the second component 223 to fix and connect the first fixing member 21 and the second fixing member 22; the third fixing portion 225 and the fourth fixing portion 211 cooperate with each other to play a guiding role, which is convenient for the installation of the first fixing member 21 and the second fixing member 22, and also plays a limiting role in the circumferential direction to avoid relative rotation between the two.

[0058] The utility model also provides a fan, please refer to Figure 1-Figure 9, comprising an air outlet body 3, a body body 4 and a shaking mechanism of the fan, wherein the air outlet body 3 is connected to the rotating assembly 1, and the body body 4 is fixedly connected to the fixing assembly 2. The shaking mechanism of the fan in the present application is used to realize the shaking function of the fan, which has a simple structure, a stable shaking effect and occupies less space.

[0059] Furthermore, in the present application, the upper part of the rotating member 11 is an arc-shaped structure for installing the air outlet body 3, the lower part of the rotating member 11 is a hollow cylinder, the rotating member 11 is assembled by two shells arranged opposite to each other, the driving member 13 is a motor, the driving member 13 is fixed in the mounting member, and the rotating shaft of the driving member 13 is connected to the connecting column 212 in the middle of the first fixing member 21 to drive the rotating member 11 and the fixing assembly 2 to rotate relative to each other; the fuselage body 4 includes a connecting rod 41 and a fuselage shell 42, and a cavity is provided inside the fuselage shell 42 for accommodating the connecting rod 41, the connecting rod 41 can be set as a telescopic rod or a hollow rod of fixed length, the connecting rod 41 in the embodiment of the present application is a telescopic rod, and the telescopic rod structure is a prior art, and the accompanying drawings only use inner and outer rods to illustrate the telescopic rod structure without a specific connecting structure, and the specific structure of the telescopic rod The structure does not belong to the protection scope of the present application.
