[0039] The present utility model provides a shaking head mechanism for a fan.

[0040] Please refer to Figures 1 to 4, in an embodiment of the present utility model, the swing mechanism of the fan includes a connecting pipe 100, a rotating assembly 200, and an elastic positioning assembly 300; the rotating assembly 200 includes a rotating seat 210, and the rotating seat 210 is rotatably connected to the connecting pipe 100; the elastic telescopic direction of the elastic positioning assembly 300 is arranged at an angle with the rotating shaft of the rotating seat 210; at least two positioning parts 101 are provided on one of the connecting pipe 100 and the rotating seat 210, and the other of them is connected with the elastic positioning assembly 300, and the elastic positioning assembly 300 is selectively clamped into a positioning part 101; when the rotating seat 210 rotates relative to the connecting pipe 100, the elastic positioning assembly 300 can slide from one positioning part 101 to another positioning part 101.

[0041] The swing mechanism of the fan refers to the mechanism for driving the fan head to swing left and right. The connecting pipe 100 refers to a fixed pipe body. When the swing mechanism of the fan is applied to a floor fan, the connecting pipe 100 can be a part or all of the support column, etc.

[0042] The rotating assembly 200 refers to an assembly that can rotate relative to the connecting pipe 100. The rotating assembly 200 includes a rotating base 210, and the rotating base 210 can be in a disc structure, a cylindrical structure or a pipe structure. The rotating assembly 200 may further include a swing motor 220. In one example, the swing motor 220 can be fixedly connected to the rotating base 210. When the rotating base 210 rotates, it can drive the swing motor 220 to rotate synchronously. That is, it can be understood that the entire swing motor 220 rotates with the rotating base 210. Specifically, the swing motor 220 and the rotating base 210 can be coaxially connected or non-coaxially connected. It can be understood that the fan may further include structures such as a fan head. The transmission shaft of the swing motor 220 is disposed through the rotating base 210 and is used to connect to the fan head. On the basis that the rotating base 210 drives the swing motor 220 to rotate together, the swing motor 220 can also drive the fan head connected to the transmission shaft of the swing motor 220 to rotate together, and there is no relative rotation between the swing motor 220 and the fan head itself. Furthermore, on the basis of realizing manual rotation of the rotating base 210 to make the swing mechanism of the fan drive the fan head to swing, the risk of damage to the swing motor 220 can be reduced. Or, in another example, the swing motor 220 can also be drivingly connected to the connecting pipe 100. When the swing motor 220 is in a working state, the swing motor 220 drives the connecting pipe 100, the rotating assembly 200, the elastic positioning assembly 300 and the fan head connected to the rotating assembly 200 to swing left and right together, so as to achieve the effect of electric swing; when the swing motor 220 is in a non-working state, the user can hold the connecting pipe 100 with one hand and hold the rotating base 210 with the other hand, and drive the rotating base 210 to rotate relative to the connecting pipe 100. Then, the rotating assembly 200 can drive the fan head connected to it to rotate together, so as to achieve the effect of manually driving the fan to swing left and right. In addition, since the swing motor 220 is only connected to the connecting pipe 100 in this example, the swing motor 220 is stationary and will not be damaged due to manually swinging the fan left and right.

[0043] The swing mechanism of the fan further includes an elastic positioning component 300, which refers to a component that can position the connecting pipe 100 and the rotating component 200 relative to each other under the action of elasticity. At least two positioning parts 101 are provided on one of the connecting pipe 100 and the rotating seat 210, and an elastic positioning component 300 is connected to the other. Without external force, the elastic positioning component 300 can be elastically snapped into one of the positioning parts 101, so as to realize the relatively fixed state of the connecting pipe 100 and the rotating seat 210, that is, the rotating component 200 in the swing mechanism of the fan can be kept stationary at a certain angle after being rotated manually to a certain angle. Under the action of external force, when the rotating seat 210 is rotated continuously, the elastic positioning component 300 can slide from one positioning part 101 to another positioning part 101, so as to realize the effect of changing the rotation angle of the rotating component 200 or switching the swing position. Specifically, the positioning part 101 can be structures such as a positioning groove or a positioning hole. The elastic positioning component 300 includes an elastic member 310 and a steel column; or the elastic positioning member 320 includes an elastic member 310 and a pin; or the elastic positioning component 300 only includes an elastic column or an elastic ball made of elastic material. The positioning part 101 can be provided on the connecting pipe 100, and the elastic positioning component 300 is connected to the rotating seat 210; or the positioning part 101 can be provided on the rotating seat 210, and the elastic positioning component 300 is connected to the connecting pipe 100.

[0044] It should be noted that in order to realize the left and right swing effect of the swing mechanism of the fan, the rotating shaft of the rotating component 200 can be arranged in the vertical direction. The elastic telescopic direction of the elastic positioning component 300 is arranged at an angle with the rotating shaft of the rotating seat 210, which means that the elastic telescopic direction of the elastic member 310 in the elastic positioning component 300 can be arranged at an acute angle, a right angle or an obtuse angle with the rotating shaft of the rotating seat 210. By arranging the elastic telescopic direction of the elastic positioning component 300 at an angle with the rotating shaft of the rotating seat 210, the risk of the rotating seat 210 and the connecting pipe 100 being separated from each other along the rotating shaft direction can be reduced during the telescopic process of the elastic positioning component 300, so as to ensure that the rotating seat 210 and the connecting pipe 100 can have a good rotating connection effect.

[0045] The technical solution of the present utility model is that by rotatably connecting the rotating seat 210 with the connecting pipe 100, when the rotating seat 210 rotates relative to the connecting pipe 100, it can drive the overall rotation of the fan head connected to the rotating assembly 200. Thus, the user can manually rotate the rotating seat 210 to achieve the effect that the shaking mechanism of the fan drives the fan head to shake. By setting the elastic positioning assembly 300, and at least two positioning parts 101 are provided on one of the connecting pipe 100 and the rotating seat 210, and the elastic positioning assembly 300 is connected to the other one. The elastic positioning assembly 300 can selectively engage with a positioning part 101, so that after the user manually rotates the rotating seat 210 to a certain angle, it remains unchanged, avoiding the risk of the rotating assembly 200 rotating easily. In addition, in the state where the rotating seat 210 rotates relative to the connecting pipe 100, the elastic positioning assembly 300 can slide from one positioning part 101 to another positioning part 101, so that the rotating assembly 200 can switch to different positions when rotating, and thus it is more convenient for the user to have more options for selecting the shaking angle. By setting the elastic telescopic direction of the elastic positioning assembly 300 at an angle with the rotating shaft of the rotating seat 210, when the elastic positioning assembly 300 undergoes elastic deformation, the risk of the rotating seat 210 separating from the connecting pipe 100 in the axial direction of its rotating shaft can be reduced. Furthermore, the connection stability between the components in the shaking mechanism of the fan is improved, and the service life of the shaking mechanism of the fan is increased.

[0046] Please refer to Figures 2 to 4 , the positioning part 101 is arranged along the circumferential direction of the connecting pipe 100 or the rotating seat 210.

[0047] With such a setting, the elastic telescopic direction of the elastic positioning assembly 300 can be perpendicular to, form an acute angle or an obtuse angle with the rotating shaft of the rotating seat 210. Furthermore, the elastic force of the elastic positioning assembly 300 on the connecting pipe 100 and the rotating seat 210 forms an angle with the rotating shaft of the rotating seat 210, thereby further reducing the risk of the rotating assembly 200 and the connecting pipe 100 separating from each other in the axial direction of the rotating seat 210, and improving the use stability of the shaking mechanism of the fan. Secondly, when the user manually rotates the rotating seat 210, the force direction is consistent with the rotation direction, and thus the radial deformation degree of the spring in the elastic positioning assembly 300 can be reduced, and the service life of the elastic positioning assembly 300 is increased.

[0048] As Figure 2 shown, in the embodiment of the present utility model, the connecting pipe 100 is connected to the rotating seat 210 through a connecting member 400. One of the rotating seat 210 and the connecting pipe 100 is provided with a rotating shaft, and the other one is provided with a shaft hole. The rotating shaft is inserted into the shaft hole, the connecting member 400 passes through the shaft hole and is connected to the rotating shaft, and the rotating seat 210 and the connecting pipe 100 can rotate relative to each other.

[0049] The connecting member 400 refers to a component used to connect the connecting pipe 100 and the rotating seat 210 without affecting the relative rotation of the rotating seat 210 with respect to the connecting pipe 100. The connecting member 400 can be a pin shaft or a screw, etc. By connecting the connecting pipe 100 and the rotating seat 210 with the connecting member 400, a good connection effect between the connecting pipe 100 and the rotating seat 210 can be achieved, and the risk of the rotating seat 210 being separated from the connecting pipe 100 under the elastic force of the elastic positioning component 300 can be further reduced. Further, by providing a rotating shaft on one of the rotating seat 210 and the connecting pipe 100 and providing a shaft hole on the other, and inserting the rotating shaft into the shaft hole, the shaft hole and the rotating shaft are radially limited to each other, so that a stable relative rotation effect between the rotating seat 210 and the connecting pipe 100 can be achieved. In addition, by passing the connecting member 400 through the shaft hole and connecting it to the rotating shaft, the connecting member 400 and the rotating seat 210 can be coaxially arranged. Further, the rotating seat 210 can rotate about the axis of the rotating shaft of the connecting member 400. While the connecting member 400 functions to connect the connecting pipe 100 and the rotating seat 210, it also functions as the rotating shaft of the rotating seat 210.

[0050] As Figure 2 shown, in an embodiment of the present utility model, the fan includes a swing motor 220, and a bracket 230 is provided inside the rotating seat 210, and the swing motor 220 is fixedly provided on the bracket 230.

[0051] By providing the bracket 230 inside the rotating seat 210 and fixedly providing the swing motor 220 on the bracket 230, on the one hand, the stability of the installation of the swing motor 220 is ensured, and it is ensured that the swing motor 220 can rotate together with the rotating seat 210; on the other hand, it also has a good protection effect on the swing motor 220, reducing the risk of interference of dust or moisture on the swing motor 220.

[0052] As Figure 2 shown, in an embodiment of the present utility model, the rotating assembly 200 further includes a joint 240, and the joint 240 is fixedly connected to the rotating seat 210.

[0053] The joint 240 is used to connect components such as the fan head of the fan. When the joint 240 is connected to the rotating seat 210, a detachable connection method or an integral structure can be adopted. When the joint 240 and the rotating seat 210 adopt a detachable connection method, such as a snap connection, a threaded connection or a pin connection, etc., it is convenient to replace the joint 240 or the rotating seat 210, and it is also convenient to disassemble and assemble the swing motor 220.

[0054] By fixedly connecting the joint 240 to the rotating seat 210, the rotating seat 210 can drive the joint 240 to rotate together when rotating, and further ensure that the fan head connected to the joint 240 can rotate together while the rotating seat 210 rotates.

[0055] Please refer to Figure 2 and Figure 4 , in the embodiment of the present utility model, one of the connecting pipe 100 and the rotating seat 210 is provided with an installation groove 102, and at least a part of the other one extends into the installation groove 102.

[0056] Specifically, in one example, the connecting pipe 100 is provided with an installation groove 102, and at least a part of the rotating seat 210 is inserted into the installation groove 102. At this time, the positioning portion 101 can be formed on the inner side wall of the connecting pipe 100, specifically on the inner side wall of the installation groove 102. In another example, the rotating seat 210 is provided with an installation groove 102, and at least a part of the connecting pipe 100 is inserted into the installation groove 102. The positioning portion 101 can be formed on the outer side wall of the connecting pipe 100.

[0057] By providing an installation groove 102 in one of the connecting pipe 100 and the rotating seat 210, and at least a part of the other one extending into the installation groove 102, the connecting pipe 100 and the rotating seat 210 are sleeved and matched, so that the rotating seat 210 can be radially limited by the connecting pipe 100 when rotating, thereby reducing the degree of radial shaking of the rotating seat 210 during rotation.

[0058] As Figure 3 shown, in the embodiment of the present utility model, the rotating seat 210 has a guiding groove 211, and one end of the elastic positioning assembly 300 extends into the guiding groove 211.

[0059] By providing a guiding groove 211 on the rotating seat 210 and one end of the elastic positioning assembly 300 extending into the guiding groove 211, a good guiding effect can be provided for the elastic telescopic process of the elastic positioning assembly 300, and at the same time, a good limiting effect on the elastic positioning assembly 300 can also be achieved.

[0060] Please refer to Figure 3 and Figure 4 , in the embodiment of the present utility model, the positioning portion 101 is a groove.

[0061] In the field of fan technology, the connecting pipe 100 or the rotating seat 210 is usually made of plastic. Plastic materials are not suitable for the drilling process. In this embodiment, by setting the positioning portion 101 as a groove, the forming process of the positioning portion 101 is more suitable for the scenario where the connecting pipe 100 and the rotating seat 210 are made of plastic. In addition, by setting the positioning portion 101 as a groove, compared with when the positioning portion 101 is a through hole, the component having the positioning portion 101 can have higher strength.

[0062] Further, as Figure 4As shown, the groove is strip-shaped, and the extending direction of the groove is arranged parallel to the rotation axis of the rotating seat 210; alternatively, the extending direction of the groove forms an acute angle or an obtuse angle with the rotation axis of the rotating seat 210.

[0063] By setting the groove to be strip-shaped, and the extending direction of the groove is parallel to, forms an acute angle or an obtuse angle with the rotation axis of the rotating seat 210, the matching difficulty between the elastic positioning component 300 and the positioning portion 101 can be reduced, and the risk of jamming when the elastic positioning component 300 slides from one positioning portion 101 to another positioning portion 101 can be reduced.

[0064] Please refer to Figure 4 and Figure 5 , in the embodiment of the present utility model, define the diameter dimension of the end face where the positioning member 320 is inserted into the positioning portion 101 as D, the depth direction of the groove is the telescopic direction of the elastic member 310, and the dimension in the depth direction of the groove is H, where D≤H≤2D.

[0065] Specifically, the dimension H in the depth direction of the groove can be D, 1.1D, 1.2D, 1.3D, 1.4D, 1.5D, 1.6D, 1.7D, 1.8D, 1.9D or 2D. By setting the dimension in the depth direction of the groove to be not less than the diameter dimension D of the end face where the positioning member 320 is inserted into the positioning portion 101, the positioning member 320 can be inserted into the positioning portion 101 to a deeper depth, thereby avoiding the risk that the positioning member 320 cannot be stably positioned within the positioning portion 101. By setting the dimension in the depth direction of the groove to be not greater than 2 times the diameter dimension of the end face where the positioning member 320 is inserted into the positioning portion 101, the risk that the positioning member 320 is inserted into the positioning portion 101 too deeply is avoided, and further the risk that a user needs a large driving force to drive the rotating assembly 200 to rotate so that the positioning member 320 can be disengaged from one positioning portion 101 and slide to another positioning portion 101 is avoided.

[0066] In the embodiment of the present utility model, define the diameter dimension of the end face where the positioning member 320 is inserted into the positioning portion 101 as D, define the width direction of the groove is perpendicular to the length direction and the depth direction of the groove, and the dimension in the width direction of the groove is W, where 0.3D≤W≤0.7D.

[0067] Specifically, the dimension W in the width direction of the groove can be 0.3D, 0.4D, 0.5D, 0.6D or 0.7D. By setting the dimension W in the width direction of the groove to be not less than 0.3D, a part of the positioning member 320 can effectively extend into the positioning portion 101, thereby ensuring good stability after a part of the positioning member 320 extends into the positioning portion 101 and avoiding the risk of the positioning member 320 easily disengaging from the positioning portion 101. By setting the dimension W in the width direction of the groove to be not greater than 0.7D, it can be avoided that the depth of the positioning member 320 extending into the positioning portion 101 is too large, which is conducive to the user driving the rotating assembly 200 to rotate with a smaller force and enabling the positioning member 320 to disengage from one positioning portion 101 and slide to another positioning portion 101, that is, the user can change the shaking position of the fan head with a smaller force and avoid the user having to use a larger driving force to change the shaking position of the fan head.

[0068] Please refer to Figure 4 and Figure 5 , in the embodiment of the technical solution of the present invention, a convex portion 103 is formed between two adjacent grooves, and a transition arc surface is formed at the connection between the groove and the convex portion 103.

[0069] By forming a convex portion 103 between two adjacent grooves and forming a transition arc surface at the connection between the groove and the convex portion 103, it is convenient for the elastic positioning assembly 300 to slide more smoothly from one positioning portion 101 to an adjacent positioning portion 101, reducing the risk of the elastic positioning assembly 300 getting stuck.

[0070] Please refer to Figure 4 and Figure 5 , in the embodiment of the technical solution of the present invention, a transition arc surface is formed at the connection between the side wall and the bottom wall of the groove.

[0071] By forming a transition arc surface at the connection between the side wall and the bottom wall of the groove, it is convenient for the elastic positioning assembly 300 to slide along the groove wall, thereby reducing the risk of the elastic positioning assembly 300 getting stuck.

[0072] Please refer to Figures 2 to 5 , in the embodiment of the technical solution of the present invention, the elastic positioning assembly 300 includes an elastic member 310 and a positioning member 320. One end of the elastic member 310 is connected to the rotating seat 210; the positioning member 320 is connected to the other end of the elastic member 310. The connecting pipe 100 is provided with a groove, and the positioning member 320 is snapped into the groove, and the end surface of the positioning member 320 snapped into the groove is an arc surface.

[0073] The elastic member 310 can be a spring, a shrapnel, or the like. The positioning member 320 can be a steel column, a pin, or the like. By connecting one end of the elastic member 310 to the rotating seat 210, connecting the positioning member 320 to the other end of the elastic member 310, and engaging the positioning member 320 into the groove of the connecting pipe 100, and the end face of the positioning member 320 engaged in the groove is an arc surface, then when there is no external force, the elastic pre-tightening force of the elastic member 310 can enable the positioning member 320 to be engaged in the groove, so as to keep the rotating seat 210 and the connecting pipe 100 relatively stationary, reducing the risk of the rotating seat 210 rotating easily; when the rotating seat 210 is rotated, the elastic member 310 and the positioning member 320 on the rotating seat 210 tend to rotate with the rotating seat 210. At this time, the positioning member 320 can slide from one groove of the connecting pipe 100 to another groove under the drive of the rotating seat 210, so as to achieve the effect of changing the shaking angle of the fan head. By including the elastic member 310 and the positioning member 320 in the elastic positioning assembly 300, when one of the elastic member 310 and the positioning member 320 is damaged, only the damaged component needs to be replaced, without replacing the entire elastic positioning assembly 300. Therefore, the replacement cost can be reduced.

[0074] Please refer to Figures 3 to 5 Further, the positioning member 320 includes a guiding column 321 and a head 322, and the elastic member 310 is sleeved outside the guiding column 321; the head 322 is connected to the guiding column 321, and the end face of the head 322 away from the guiding column 321 is an arc surface.

[0075] By sleeving the elastic member 310 outside the guiding column 321 of the positioning member 320, a good guiding effect can be provided for the elastic telescopic direction of the elastic member 310, reducing the risk that the elastic member 310 is inclined and the positioning member 320 cannot be positioned in the positioning portion 101. In addition, by connecting the head 322 to the guiding column 321, the head 322 can be inserted into the positioning portion 101 for positioning. And by making the end face of the head 322 away from the guiding column 321 an arc surface, the head 322 can slide smoothly relative to the positioning portion 101 during the rotation of the rotating seat 210, reducing the risk of it being stuck in a certain positioning portion 101, so as to facilitate the head 322 to slide from one positioning portion 101 to another positioning portion 101, and further achieve the effect of shifting gears when the fan head shakes.

[0076] In the embodiment of the present utility model, at least two groups of elastic positioning assemblies 300 are provided, and at least two groups of elastic positioning assemblies 300 are arranged in an array along the rotating shaft of the rotating seat 210.

[0077] With such a setting, the rotating seat 210 is better positioned, more balanced and stable after rotation.

[0078] Specifically, when there are two sets of elastic positioning components 300, the two sets of elastic positioning components 300 can be symmetrically distributed along the rotation axis of the rotating seat 210. When there are three sets of elastic positioning components 300, the included angle between every two adjacent sets of the three sets of elastic positioning components 300 can be set to 120°.

[0079] The present utility model further provides a fan, which includes a column tube, a machine head, and a swing mechanism of the fan. The specific structure of the swing mechanism of the fan refers to the above embodiments. Since this fan adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated herein one by one. Among them, the connecting tube 100 is arranged above the column tube, and the rotating seat 210 is arranged below the machine head. With such an arrangement, the rotating seat 210 and the connecting tube 100 are at a more appropriate height, which is convenient for the user to hold the rotating seat 210, or the connecting tube, or the column tube by hand to adjust the left and right swinging direction of the machine head.

[0080] The above description is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
