The machine head body is rotatably arranged on the assembly support around a first axis. The first rotating seat and the second rotating seat are in running fit around a second axis, and the direction of the second axis intersects with the direction of the first axis. The assembling support is arranged on the first rotating base, and the second rotating base is fixedly connected with a fan body assembly of the fan.

After long-term use, the wire body and wire core will be severely worn or even broken, which will affect the normal operation of the fan. Summary of the invention

[0044] In addition, if the term "and / or" appears, "and / or" is merely a way to describe the association relationship between associated objects, and indicates that three relationships may exist, for example, A and / or B can represent the association relationship between A and B: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that there is an "or" relationship between the associated objects before and after it. If the terms "first" and "second" appear, these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0048] See also Figures 1 to 9The head assembly 100 provided in one embodiment of the present application includes a head body 10, an assembly support 20, a first rotating seat 31 and a second rotating seat 32. The head body 10 is rotatably arranged on the assembly support 20 around a first axis. The first rotating seat 31 and the second rotating seat 32 are rotatably matched around a second axis, and the direction of the second axis intersects with the direction of the first axis. The assembly support 20 is arranged on the first rotating seat 31, and the second rotating seat 32 is used to fix the fuselage assembly 210 connected to the fan 200. Among them, the assembly support 20 has a first wire-passing channel 21, and the first rotating seat 31 has a second wire-passing channel 311.

[0049] The head assembly 100 is used for the fan 200, and the fan 200 can be but not limited to a circulation fan. The fan 200 also includes a body assembly 210, and the head assembly 100 is connected to the body assembly 210. Specifically, the body assembly 210 includes a body rod 211 and a chassis 212, the head assembly 100 is connected to the top end of the body rod 211, and the chassis 212 is connected to the bottom end of the body rod 211. It can be understood that in order to achieve its normal function, the head body 10 includes a main motor 11, a fan blade 12, a casing 13, etc. Among them, the main motor 11 and the fan blade 12 are installed in the casing 13. The main motor 11 is connected to the fan blade 12 in a transmission manner, and is used to drive the fan blade 12 to rotate to form an air supply airflow.

[0050] The direction of the second axis intersects with the direction of the first axis, that is, the head body 10 can rotate in two different directions. Among them, the direction of the first axis is the first direction, and the first direction intersects with the height direction of the fan 200. The height direction of the fan 200 is the vertical direction when it is in normal use. The direction of the second axis is the second direction, and the second direction intersects with the horizontal direction. It can be understood that the second direction also intersects with the first direction. For ease of understanding, the following description is based on the first direction as the horizontal direction, and specifically the left and right direction of the fan 200, and the second direction as the vertical direction.

[0051] The head body 10 rotates around the first axis to achieve up and down shaking. At the same time, the head body 10 is indirectly arranged on the first rotating seat 31 through the assembly support 20, and the first rotating seat 31 can rotate around the second axis relative to the second rotating seat 32, and the second rotating seat 32 is fixed on the fuselage rod 211 of the fuselage assembly 210. Therefore, when the first rotating seat 31 rotates around the second axis relative to the second rotating seat 32, the assembly support 20 located on the first rotating seat 31 and the head body 10 located on the assembly support 20 rotate together accordingly to achieve left and right shaking of the head body 10.

[0052] It can be understood that the head assembly 100 also includes a line 40, and the line 40 terminal at one end of the line 40 can be plugged into the control panel of the head body 10, and the line 40 terminal at the other end can be connected to an external power supply or a controller, etc. In addition, the line 40 can also be used to power the main motor 11, etc. Specifically, the line 40 can pass through the second line passage 311 and the first line passage 21 from bottom to top to reach the head body 10 and be electrically connected thereto. In addition, the head assembly 100 can also include a shell 24, the assembly support 20 can be arranged on the shell 24, the first rotating seat 31 is arranged in the shell 24, and the shell 24 can be directly or indirectly connected to the first rotating seat 31 and can rotate therewith.

[0053] The head assembly 100, the assembly support 20 and the first rotating seat 31 are respectively used to realize the up and down shaking function and the left and right shaking function of the head assembly 100. Among them, the assembly support 20 and the first rotating seat 31 both have a wire passing channel for the line 40 to be routed, and the assembly support 20 is arranged on the first rotating seat 31 and can rotate therewith. Therefore, when the head assembly 100 is shaking its head, there is no relative rotation between the assembly support 20 and the first rotating seat 31, so the line 40 routed through the first wire passing channel 21 and the second wire passing channel 311 will not be obviously pulled and bent by the two. In this way, the influence of the shaking function of the head assembly 100 on the routing is reduced, and the wear and even breakage of the wire body and wire core due to shaking of the head is alleviated, which helps to increase the service life of the fan 200.

[0054] Furthermore, an edge curve of a cross section of the first wire passing channel 21 and / or the second wire passing channel 311 is a smooth curve.

[0055] It can be understood that the edge curve is a smooth curve, which means that the boundary line of the cross section of the first wire passage 21 and / or the second wire passage 311 does not have edges and corners, but is a smooth closed curve. In other words, there is a tangent at each point on the boundary line of the cross section of the first wire passage 21 and / or the second wire passage 311, and the tangent rotates continuously with the movement of the tangent point.

[0056] In this way, there are no sharp edges or spikes in the wire channel defined by the edge curve. Therefore, even if the line 40 moves in the wire channel, the damage to the line 40 is relatively small, which helps to reduce the negative impact of the wire channel on the line 40 when the wiring harness moves.

[0057] In some embodiments, the cross-sectional area of ​​the first wire-passing channel 21 is S1, and the cross-sectional area of ​​the line 40 in the first wire-passing channel 21 is S2, then S1 ≥ 2·S2.

[0058] It can be understood that the size of the first wire-passing channel 21 is significantly larger than the size of the wire 40 therein, and the wire 40 can move in the first wire-passing channel 21 .

[0059] In this way, the first wire passage 21 can allow the wire 40 therein to move appropriately, so that the wire 40 can be located in the first wire passage 21 in a more natural manner, thereby reducing the probability of the wire 40 being pulled, bent, and subjected to excessive force.

[0060] In some embodiments, the cross-sectional area of ​​the second wire-passing channel 311 is S3, and the cross-sectional area of ​​the line 40 in the second wire-passing channel 311 is S4, then S3 ≥ 2·S4.

[0061] It can be understood that the size of the second wire-passing channel 311 is significantly larger than the size of the wire 40 therein, and the wire 40 can move in the second wire-passing channel 311 .

[0062] In this way, the second wire-passing channel 311 can allow the wire 40 therein to move appropriately, so that the wire 40 can be placed in the second wire-passing channel 311 in a more natural manner, reducing the probability of it being pulled, bent, and subjected to excessive force. The wire 40 can also increase its length according to the relative movement stroke of the up and down shaking. When the up and down shaking is not turned on, the excess length of the wire 40 is accommodated in the wire-passing channel.

[0063] Please also read Fig.10 In some embodiments, the line 40 is arranged through the first wire passage 21 and the second wire passage 311. The line 40 is at least partially a spring line 41, and is electrically connected to the head body 10 through the spring line 41. It can be understood that the spring line 41 can undergo elastic deformation to perform expansion and contraction.

[0064] In this way, even if the line 40 is pushed or pulled, the spring wire 41 can adapt by expanding and contracting to reduce the impact of the push and pull.

[0065] Please also read Figures 11 to 15 In some embodiments, the head assembly 100 also includes an oscillating motor 50, which is disposed on the first rotating seat 31 and is used to drive the head body 10 to rotate around the first axis and the first rotating seat 31 to rotate around the second axis relative to the second rotating seat 32.

[0066] It can be understood that the oscillating motor 50 is arranged on the first rotating seat 31, and is specifically located in the housing 24, and can rotate left and right with the head body 10 to be stationary in the left and right direction relative to the head body 10. On this basis, the oscillating motor 50 can better drive the head body 10 to oscillate up and down.

[0067] In this way, the head assembly 100 can achieve the drive of the head body 10 to shake left and right and shake up and down only by the shaking motor 50, that is, a single motor can achieve two-way shaking, which helps to reduce the number of its own parts and the number of lines 40. With the reduction of the number of lines 40, the difficulty of wiring is correspondingly reduced, and the faults caused by the lines 40 are also reduced.

[0068] In some embodiments, the head assembly 100 further includes a transmission mechanism, and the shaking head motor 50 is connected to the head body 10 through the transmission mechanism, so as to drive the head body 10 to rotate around the first axis through the transmission mechanism.

[0069] The transmission mechanism includes a transmission member, which is disposed on the machine head body 10 and extends around the first axis. The oscillating motor 50 is connected to the machine head body 10 through the transmission member.

[0070] The transmission member is fixedly connected to the head body 10, and can drive the head body 10 to rotate when driven by the oscillating motor 50. The transmission member can be in an arc shape around the first axis, and the arc can be but not limited to π, π / 2, etc., which is not specifically limited here.

[0071] In this way, the oscillating motor 50 can drive the head body 10 to rotate around the first axis by driving the transmission member extending around the first axis to rotate.

[0072] Furthermore, the transmission member is a rack 61 , which is disposed on the head body 10 and around the first axis. The transmission mechanism also includes a transmission gear 62 , which is connected to the oscillating motor 50 and meshes with the rack 61 .

[0073] The transmission gear 62 is driven to rotate by the oscillating motor 50 , and when rotating, it drives the rack 61 meshing with it to rotate around the first axis, thereby driving the head body 10 to oscillate up and down.

[0074] Thus, the oscillating motor 50 is connected to the machine head body 10 through the transmission gear 62 and the rack 61, and drives the machine head body 10 to oscillate up and down. In addition, the section from the second wire-passing channel 311 to the first wire-passing channel 21 is independent of the transmission gear 62 and is not affected by the movement of the transmission gear 62.

[0075] Furthermore, the housing 13 of the head body 10 has a mounting portion 131 , which is arc-shaped and has a first axis. The rack 61 is mounted on the mounting portion 131 , and the spring wire 41 is at least partially assembled in the mounting portion 131 .

[0076] Specifically, the housing 13 also has an air inlet and an air outlet. The mounting portion 131 is located in the direction of the air inlet. The rack 61 is disposed on the side of the mounting portion 131 facing away from the air inlet. The meshing teeth of the rack 61 are located on the side facing away from the mounting portion 131.

[0077] The rack 61 has a first screw hole 611, and the mounting portion 131 has a first screw column 1311 that matches the first screw hole 611, and the two are connected by screws. In addition, the housing 13 may also include a decorative shell 132, which is disposed on a side of the rack 61 that is away from the mounting portion 131, and at the same time, the decorative shell 132 has a through hole, and the meshing teeth of the rack 61 are exposed at the through hole so as to mesh with the transmission gear 62.

[0078] In this way, the spring wire 41 can be extended and retracted in the mounting portion 131 when the head body 10 moves up and down.

[0079] In some embodiments, the driving shaft of the shaking motor 50 is arranged parallel to the second axis, and the transmission gear 62 includes a first gear 621 and a second gear 622. The first gear 621 is configured with an axis parallel to the second axis, and the second gear 622 is configured with an axis parallel to the first axis.

[0080] The ends of the first gear 621 and the second gear 622 have gear shafts. The first gear 621 has a first conical tooth portion, and the second gear 622 has a second conical tooth portion and a second columnar tooth portion. The second conical tooth portion meshes with the first conical tooth portion, and the second columnar tooth portion meshes with the rack 61.

[0081] In addition, the head assembly 100 may further include a driving gear 51, which is sleeved on the driving shaft of the oscillating motor 50. The first gear 621 also has a first cylindrical tooth portion, and is meshed with the driving gear 51 through the first cylindrical tooth portion.

[0082] In this way, the torque output by the shaking motor 50 can be converted into the required direction by the first gear 621 and the second gear 622 that cooperate with each other, and then the second cylindrical tooth portion of the second gear 622 drives the head body 10 to rotate around the first axis through the rack 61.

[0083] Furthermore, the second gear 622 has two sets of second cylindrical teeth, and the two sets of second cylindrical teeth are respectively located on both sides of the second conical teeth in the axial direction.

[0084] The rack 61 has a first tooth portion 612 and a second tooth portion 613, which are respectively meshed with two groups of second cylindrical tooth portions, and the first tooth portion 612 and the second tooth portion 613 are spaced apart in the axial direction of the second gear 622 to form a strip-shaped opening 614 that avoids the second conical tooth portion, and the strip-shaped opening 614 is connected to the mounting portion 131.

[0085] It can be understood that the first tooth portion 612 is meshed with the second cylindrical tooth portion on one side of the second gear 622 , and the second tooth portion 613 is meshed with the second cylindrical tooth portion on the other side of the second gear 622 .

[0086] This helps to improve the transmission stability between the rack 61 and the second gear 622 . The strip-shaped opening 614 can avoid the second conical tooth portion on the one hand, and can also allow the line 40 to pass through and extend into the nose body 10 on the other hand.

[0087] In some embodiments, the assembly support 20 has an arcuate mating surface 22, the axis of the arcuate mating surface 22 is the first axis, the head body 10 is matched with the arcuate mating surface 22 through the mounting portion 131, and can slide along the arcuate mating surface 22 to rotate around the first axis.

[0088] Since the axis of the arc-shaped matching surface 22 is the first axis, the head body 10 can rotate around the first axis by sliding along the arc-shaped matching surface 22 through the mounting portion 131 .

[0089] In this way, the head body 10 can achieve stable rotation relative to the assembly support 20 by sliding along the arc-shaped matching surface 22 .

[0090] Please also read Fig.16 Specifically, the assembly support 20 includes a support body 23, a shell 24 and a limiting cover (not shown), and the support body 23 forms an arc-shaped mating surface 22. The shell 24 is assembled on the first rotating seat 31 and can be connected to the first rotating seat 31 by screws. The top of the shell 24 has a mounting groove 241, and the support body 23 is arranged in the mounting groove 241, and the top of the support body 23 can pass through the rack 61 through the strip-shaped opening 614 to cooperate with the mounting portion 131. In addition, the top of the shell 24 can also form a gear groove 242, and the second gear 622 is installed in the gear groove 242. The limiting cover is covered on the arc-shaped mating surface 22 of the support body 23, and the mounting portion 131 is at least partially located between the support body 23 and the limiting cover, so as to limit the mounting portion 131 between the two to prevent the head body 10 from detaching.

[0091] Furthermore, the assembly support 20 further includes a supporting roller 25 , the axial direction of the supporting roller 25 is parallel to the first axis, the supporting roller 25 is disposed on the support body 23 and located at the arc-shaped mating surface 22 , and rollingly supports the mounting portion 131 .

[0092] In this way, the supporting roller 25 can support the mounting portion 131 and make it slide more smoothly along the arc-shaped mating surface 22, which helps the head body 10 to shake up and down.

[0093] Specifically, the support roller 25 includes an outer roller and an inner roller. The support body 23 has a first axial hole 231 and a second axial hole 232. The outer roller is installed on the support body 23 through the first axial hole 231, and the inner roller is installed on the support body 23 through the second axial hole 232.

[0094] Please also read Fig.17 and Fig.18 In some embodiments, the driving shaft of the shaking motor 50 includes a first driving shaft 52 and a second driving shaft 53. The first driving shaft 52 is connected to the head body 10 in a transmission manner, and the second driving shaft 53 is engaged with the second rotating seat 32 in a rotation direction around the second axis.

[0095] The oscillating motor 50 is a dual-axis motor, and both driving shafts can be parallel to the second axis. The driving gear 51 is sleeved on the first driving shaft 52 of the oscillating motor 50. The first rotating seat 31 has a mounting position for mounting the oscillating motor 50, and the oscillating motor 50 has a second screw hole 54. The first rotating seat 31 has a second screw column 312 that matches the second screw hole 54. The oscillating motor 50 is fixed to the first rotating seat 31 by screw fixing through the second screw hole 54 and the screw column. In addition, the first rotating seat 31 also has a column 313 for rotating and mounting the second gear 622.

[0096] The second drive shaft 53 is engaged with the second rotating seat 32 to prevent rotation. Since the second rotating seat 32 is fixed on the fuselage rod 211, when the second drive shaft 53 outputs torque, a reaction force will be generated to drive the shaking motor 50 to drive the first rotating seat 31 to rotate, and then drive the assembly support 20 and the head body 10 to rotate around the second axis.

[0097] In this way, the oscillating motor 50 can drive the oscillation up and down and left and right through the two driving shafts.

[0098] Further, the end section of the second drive shaft 53 is non-circular, and the second rotating seat 32 has a matching shaft hole 321 that matches the end of the second drive shaft 53. It can be understood that the matching shaft hole 321 is non-circular that matches the end of the second drive shaft 53.

[0099] Specifically, the end section of the first drive shaft 52 is also non-circular, and the ends of the first drive shaft 52 and the second drive shaft 53 can be flat, and accordingly, the mating shaft hole 321 is also flat. Similarly, the driving gear 51 has a flat shaft hole, and the end of the first drive shaft 52 is inserted into the shaft hole of the driving gear 51 to achieve a non-rotational fit between the two.

[0100] In this way, the end of the second driving shaft 53 is inserted into the matching shaft hole 321 , so that the second driving shaft 53 and the second rotating seat 32 can be locked in rotation.

[0101] Furthermore, the first rotating seat 31 has a rotating shaft structure 314, which extends along the direction of the second axis, and the second rotating seat 32 has a rotating groove 322 that cooperates with the rotating shaft structure 314. One of the rotating shaft structure 314 and the rotating groove 322 has a buckle 323 (such as Figure 3 As shown in FIG. 1 ), the other has a slot 3141, which engages with the buckle 323 to generate a limit in the direction of the second axis.

[0102] Specifically, the rotating shaft structure 314 is hollow, the rotating groove 322 is arranged around the matching shaft hole 321 , and the second driving shaft 53 passes through the rotating shaft structure 314 and matches with the matching shaft hole 321 .

[0103] In this way, the first rotating seat 31 can rotate with the second rotating seat 32 around the second axis through the rotating shaft structure 314, and the buckle 323 cooperates with the slot 3141 to reduce the probability of abnormal separation of the two.

[0104] Furthermore, the surface of the second rotating seat 32 that cooperates with the first rotating seat 31 has an annular groove 324. The annular groove 324 is formed around the second axis and can constrain and guide the first rotating seat 31 to rotate.

[0105] In some embodiments, the head assembly 100 may further include a clutch mechanism for controlling whether the transmission gear 62 transmits power between the shaking motor 50 and the rack 61 .

[0106] In other words, the transmission gear 62 has a transmission state and a non-transmission state, and in the transmission state, the oscillating motor 50 is in transmission connection with the rack 61, and in the non-transmission state, the oscillating motor 50 is not in transmission connection with the rack 61. The clutch mechanism can control the transmission gear 62 to switch between the transmission state and the non-transmission state.

[0107] In this way, when there is no need to shake the head up and down, the transmission gear 62 can be controlled to be in a non-transmission state through the clutch mechanism, so that the shaking motor 50 can no longer drive the head body 10 to rotate around the first axis through the transmission mechanism.

[0108] In the above-mentioned machine head assembly 100, the shaking head motor 50 is installed on the first rotating seat 31, and the shaking head motor 50 is provided with a first driving shaft 52 and a second driving shaft 53. A driving gear 51 is installed on the first driving shaft 52, and the driving gear 51 is meshed with the first gear 621. The first gear 621 is a two-stage compound gear, the first stage is the first cylindrical tooth portion meshed with the driving gear 51, the second stage is the first bevel tooth portion, and is meshed with the second bevel gear of the second gear 622. The second gear 622 is also a two-stage compound gear, the first stage is the second bevel gear, and the second stage is the second cylindrical tooth portion on both sides. The second cylindrical tooth portions on both sides of the second gear 622 are meshed with the rack 61, and the rack 61 is fixed on the machine head body 10.

[0109] When the shaking motor 50 is running, the first drive shaft 52 drives the active gear 51, and then drives the first gear 621, and then drives the second gear 622, and finally drives the rack 61 to rotate, completing the up and down shaking movement of the whole machine. The shaking second drive shaft 53 is inserted into the matching shaft hole 321 of the second rotating seat 32, and directly drives the first rotating seat 31 and the parts installed on the first rotating shaft to rotate together through the reaction force to complete the left and right shaking movement. A second wire-passing channel 311 is provided on the first rotating seat 31, and a first wire-passing channel 21 is provided on the assembly support 20. This assembly support 20 passes through the rack 61 and is fixed to the housing 24 by screws. The line 40 passes through the second wire-passing channel 311 of the first rotating seat 31 from bottom to top, vertically upward, and then passes through the first wire-passing channel 21 of the assembly support 20 to reach the head body 10. This section from the second wire-passing channel 311 to the first wire-passing channel 21 is independent of the transmission gear 62 and is not affected by the movement of the transmission gear 62. Then, the line 40 follows the curvature of the mounting portion 131 of the machine head body 10, and the line 40 located in the mounting portion 131 is a spring line 41. The line 40 passes through the wire hole of the machine head body 10, and the terminal of the line 40 is plugged into the control board. Therefore, when the head is turned on, no matter whether the machine head body 10 swings up and down or left and right, the entire section of the line 40 will not be pulled back and forth or bent back and forth. When the head is shaken, the line 40 is naturally straight. Only when the head is shaken up and down, due to the relative movement of the head body 10 and the shell 24, there will be a slight pull at the junction of the head body 10 and the assembly support 20, but when the head is shaken up and down, the elastic force of the spring line 41 can be relied on to resist the slight pulling force, and the relative movement amplitude of the internal wire core is small, which helps to extend the service life of the line 40.

[0110] In addition, the line 40 can also increase its length according to the relative movement stroke of the up and down shaking head. When the up and down shaking head is not turned on, the excess line length of the line 40 is placed in the line passing channel of the head body 10. When the up and down shaking head moves to the extreme position, the line 40 is unfolded and will not be excessively pulled.

[0111] In this way, the head assembly 100 can drive the head body 10 to shake up and down and left and right at the same time through the shaking motor 50, which not only reduces the number of parts, but also reduces the number of lines 40. In addition, the shaking motor 50 and the assembly support 20 are both installed on the first rotating seat 31, and rotate accordingly, and the line 40 passes through the line passage on the assembly support 20 and the first rotating seat 31, and extends to the mounting portion 131 to connect to the head body 10. The line 40 located in the mounting portion 131 is a spring line 41. In this way, when the head assembly 100 performs a large-angle multi-directional shaking motion, the line 40 is less bent and pulled, and the wiring is simple and reliable, which helps to improve the line life of the product during long-term shaking operation.

[0112] The present application also provides a fan 200, comprising the above-mentioned head assembly 100. It can be understood that, in order to achieve its normal function, the fan 200 also includes a body assembly 210, and the head assembly 100 is connected to the body assembly 210.
