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. The assembling support is provided with a first wire passing channel, and the first rotating base is provided with a second wire passing channel. According to the machine head assembly, the assembling support and the first rotating base are used for achieving the up-down and left-right head shaking function respectively, and when head shaking is conducted, the assembling support and the first rotating base do not rotate relatively, so that a line passing through the first line passing channel and the second line passing channel is not obviously pulled and bent by the first line passing channel and the second line passing channel. Therefore, the influence of head shaking on wiring is reduced, the situation that the wire body and the wire core are abraded and even broken is relieved, and the service life of the fan is prolonged.

Description

Technical Field

[0001] This application relates to the field of electrical technology, and in particular to a head assembly and a fan. Background Technology

[0002] To expand the air delivery range, the fan is equipped with an oscillation function. In addition, the fan can also have two modes: up-and-down oscillation and left-and-right oscillation.

[0003] In related technologies, to simultaneously support two modes, some fans are equipped with two oscillating motors, one driving the vertical oscillation and the other driving the horizontal oscillation. However, fans using this mode require controlling and powering two oscillating motors, resulting in a large number of internal circuits. Furthermore, the wires are subjected to significant bending and stretching during large-angle oscillations, leading to severe wear and even breakage of the wires after prolonged use, thus affecting the normal operation of the fan. Utility Model Content

[0004] Therefore, it is necessary to provide a head assembly and fan that can reduce the impact of the oscillation function on the wiring to address the above problems.

[0005] A fan head assembly for use with a fan, the fan head assembly comprising:

[0006] The main body of the aircraft head;

[0007] Assembly support, wherein the head body is rotatably mounted on the assembly support about a first axis; and

[0008] A first rotating seat and a second rotating seat are provided, wherein the first rotating seat and the second rotating seat are rotatably engaged around a second axis, the direction of which the second axis intersects the direction of which the first axis is located; the mounting support is provided on the first rotating seat, and the second rotating seat is used to fix and connect the fan body assembly;

[0009] The assembly support has a first wire passage, and the first rotating seat has a second wire passage.

[0010] In one embodiment, the head assembly further includes a sway motor, which is disposed on the first rotating seat and is used to drive the head body to rotate about the first axis and the first rotating seat to rotate relative to the second rotating seat about the second axis.

[0011] In one embodiment, the head assembly further includes wiring that passes through the first wiring channel and the second wiring channel; the wiring is at least partially spring wire and is electrically connected to the head body via the spring wire.

[0012] In one embodiment, the head assembly includes a rack and a transmission gear. The rack is disposed on the head body and arranged around the first axis. The transmission gear is connected to the oscillating motor and meshes with the rack.

[0013] In one embodiment, the head body includes a housing, the housing having a mounting portion, the mounting portion being arc-shaped and having an axis equal to the first axis, the rack being mounted on the mounting portion, and the spring wire being at least partially assembled within the mounting portion.

[0014] In one embodiment, the transmission gear includes a first gear and a second gear, the first gear being configured with its axis parallel to the second axis, and the second gear being configured with its axis parallel to the first axis;

[0015] The first gear has a first conical tooth portion, the second gear has a second conical tooth portion and two sets of second cylindrical teeth portions, the second conical tooth portion meshes with the first conical tooth portion, and the two sets of second cylindrical teeth portions are respectively located on both sides of the second conical tooth portion in the axial direction;

[0016] The rack has a first tooth and a second tooth, the first tooth and the second tooth respectively meshing with two sets of second cylindrical teeth, and the first tooth and the second tooth are spaced apart in the axial direction of the second gear to form a strip-shaped opening, the strip-shaped opening communicating with the mounting part.

[0017] In one embodiment, the mounting support has an arc-shaped mating surface, the axis of which is the first axis, and the machine head body engages with the arc-shaped mating surface through the mounting part and is able to slide along the arc-shaped mating surface.

[0018] In one embodiment, the oscillating motor has a first drive shaft and a second drive shaft, the first drive shaft being drively connected to the head body, and the second drive shaft engaging with the second rotating seat in a rotational direction around the second axis.

[0019] In one embodiment, the edge curves of the cross-sections of the first and / or second cable channels are smooth curves.

[0020] A fan, including the aforementioned head assembly.

[0021] The aforementioned head assembly and fan, along with the mounting bracket and the first rotating base, are used to realize the up-and-down and left-and-right oscillation functions of the head assembly, respectively. Both the mounting bracket and the first rotating base have cable routing channels, and the mounting bracket, located on the first rotating base, can rotate with it. Therefore, when the head assembly oscillates, there is no relative rotation between the mounting bracket and the first rotating base, preventing significant pulling or bending of the cables running through the first and second cable routing channels. This reduces the impact of the head assembly's oscillation function on cable routing, mitigating wear and even breakage of the cable cores due to oscillation, and contributing to a longer fan lifespan.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0043] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0044] Furthermore, where the term "and / or" appears, it merely describes the relationship between related objects and indicates that three relationships can exist. For example, A and / or B can represent the relationship between A and B: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this document generally indicates an "or" relationship between the related objects before and after it. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature specified with "first" or "second" may explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, four, five, etc., unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0046] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0047] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element.

[0048] Please see Figures 1 to 9An embodiment of this application provides a head assembly 100, including a head body 10, a mounting bracket 20, a first rotating base 31, and a second rotating base 32. The head body 10 is rotatably mounted on the mounting bracket 20 about a first axis. The first rotating base 31 and the second rotating base 32 are rotatably engaged about a second axis, the direction of which intersects the direction of the first axis. The mounting bracket 20 is mounted on the first rotating base 31, and the second rotating base 32 is used to fixably connect the body assembly 210 of the fan 200. The mounting bracket 20 has a first wire passage 21, and the first rotating base 31 has a second wire passage 311.

[0049] The head assembly 100 is used for the fan 200, which can be, but is not limited to, a circulating fan. The fan 200 also includes a body assembly 210, to which the head assembly 100 is connected. 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. Understandably, to achieve its normal function, the head body 10 includes a main motor 11, fan blades 12, and a housing 13. The main motor 11 and fan blades 12 are installed inside the housing 13. The main motor 11 is connected to the fan blades 12 and drives the fan blades 12 to rotate, thereby forming an airflow.

[0050] The direction of the second axis intersects the direction of the first axis, meaning the head body 10 can rotate in two different directions. The first axis is the first direction, which intersects the height direction of the fan 200, which is the vertical direction during normal use. The second axis is the second direction, which intersects the horizontal direction and, understandably, also intersects the first direction. For ease of understanding, the following explanation will use the first direction as the horizontal direction, specifically the left-right direction of the fan 200, and the second direction as the vertical direction.

[0051] The head body 10 rotates around a first axis to achieve up-and-down yaw motion. Simultaneously, the head body 10 is indirectly mounted on a first rotating seat 31 via a mounting bracket 20. The first rotating seat 31 can rotate relative to a second rotating seat 32 around a second axis, and the second rotating seat 32 is fixed to the body rod 211 of the body assembly 210. Therefore, when the first rotating seat 31 rotates relative to the second rotating seat 32 around the second axis, the mounting bracket 20 on the first rotating seat 31 and the head body 10 mounted on the mounting bracket 20 rotate accordingly, achieving left-and-right yaw motion of the head body 10.

[0052] Understandably, the head assembly 100 also includes a wiring 40. One end of the wiring 40 can be plugged into the control board of the head body 10, and the other end can be connected to an external power supply or controller. Furthermore, the wiring 40 can also be used to power the main motor 11. Specifically, the wiring 40 can pass from bottom to top through the second wiring channel 311 and the first wiring channel 21 to reach the head body 10 and be electrically connected thereto. In addition, the head assembly 100 may also include a housing 24, a mounting bracket 20 can be disposed on the housing 24, and a first rotating seat 31 is disposed inside the housing 24. The housing 24 can be directly or indirectly connected to the first rotating seat 31 and can rotate with it.

[0053] The aforementioned fan head assembly 100, with its mounting bracket 20 and first rotating base 31, respectively enables the fan head assembly 100 to oscillate up and down and left and right. Both the mounting bracket 20 and the first rotating base 31 have cable passages for the wiring 40, and the mounting bracket 20, located on the first rotating base 31, can rotate with it. Therefore, when the fan head assembly 100 oscillates, there is no relative rotation between the mounting bracket 20 and the first rotating base 31, preventing significant pulling and bending of the wiring 40 passing through the first cable passage 21 and the second cable passage 311. This reduces the impact of the fan head assembly 100's oscillation function on the wiring, mitigating wear and even breakage of the wires due to oscillation, and contributing to a longer service life for the fan 200.

[0054] Furthermore, the edge curves of the cross-sections of the first wire-passing channel 21 and / or the second wire-passing channel 311 are smooth curves.

[0055] Understandably, a smooth curve refers to a curve whose boundary line of the cross-section of the first through-channel 21 and / or the second through-channel 311 has no sharp corners, but is a smooth closed curve. In other words, there is a tangent at every point on the boundary line of the cross-section of the first through-channel 21 and / or the second through-channel 311, and the tangent rotates continuously as the point of tangency moves.

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

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

[0058] Understandably, the size of the first wire passage 21 is significantly larger than the size of the wire 40 inside it, and the wire 40 can move within the first wire passage 21.

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

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

[0061] Understandably, the size of the second cable passage 311 is significantly larger than the size of the cable 40 inside it, and the cable 40 can move within the second cable passage 311.

[0062] Thus, the second cable passage 311 allows the cable 40 within it to move appropriately, so that the cable 40 can be positioned more naturally within the second cable passage 311, reducing the probability of it being pulled, bent, or subjected to excessive force. The cable 40 can also increase its length according to the relative movement of the up-and-down oscillation. When the up-and-down oscillation is not activated, the excess length of the cable 40 is accommodated within the cable passage.

[0063] Please refer to the following: Figure 10 In some embodiments, the wire 40 passes through the first wire passage 21 and the second wire passage 311. The wire 40 is at least partially a spring wire 41, and is electrically connected to the head body 10 via the spring wire 41. Understandably, the spring wire 41 is capable of elastic deformation to extend or retract.

[0064] In this way, even if the line 40 is pushed or pulled, it can adapt by the extension and retraction of the spring line 41 to reduce the impact of pushing and pulling.

[0065] Please refer to the following: Figures 11 to 15 In some embodiments, the head assembly 100 further includes a sway 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 relative to the second rotating seat 32 around the second axis.

[0066] Understandably, the oscillating motor 50 is located on the first rotating base 31 and specifically inside the outer casing 24, and can rotate left and right along with the head body 10 so as to remain stationary relative to the head body 10 in the left and right directions. Based on this, the oscillating motor 50 can better drive the head body 10 to oscillate up and down.

[0067] In this way, the head assembly 100 achieves the left-right and up-down swaying of the head body 10 using only the swaying motor 50, that is, a single motor achieves bidirectional swaying, which helps to reduce the number of its own parts and the number of wires 40. As the number of wires 40 decreases, the wiring difficulty is reduced accordingly, and the failures caused by the wires 40 also decrease.

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

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

[0070] The transmission component 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 component can be in the shape of an arc around the first axis, and the arc can be, but is not limited to, π, π / 2, etc., which are not specifically limited here.

[0071] Thus, the oscillating motor 50 can drive the transmission component extending around the first axis to rotate, thereby causing the head body 10 to rotate around the first axis.

[0072] Furthermore, the transmission component is a rack 61, which is disposed on the head body 10 and arranged 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 it rotates, 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 head body 10 via the transmission gear 62 and rack 61, thereby driving the head body 10 to oscillate up and down. In addition, this section of the path from the second wire passage 311 to the first wire passage 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 part 131, which is arc-shaped and has a first axis. The rack 61 is mounted on the mounting part 131, and the spring wire 41 is at least partially assembled in the mounting part 131.

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

[0077] The rack 61 has a first screw hole 611, and the mounting part 131 has a first screw post 1311 that mates with the first screw hole 611; the two are connected by screws. Furthermore, the housing 13 may also include a decorative shell 132, which covers the side of the rack 61 facing away from the mounting part 131. The decorative shell 132 has a through hole through which the meshing teeth of the rack 61 are exposed for meshing with the transmission gear 62.

[0078] In this way, the spring cable 41 can extend and retract within the mounting part 131 when the head body 10 swings up and down.

[0079] In some embodiments, the drive shaft of the oscillating 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 its axis parallel to the second axis, and the second gear 622 is configured with its 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 cylindrical tooth portion. The second conical tooth portion meshes with the first conical tooth portion, and the second cylindrical tooth portion meshes with the rack 61.

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

[0082] Thus, the torque output by the oscillating motor 50 can be converted into the desired direction by the cooperating first gear 621 and second gear 622, and then driven by the second cylindrical teeth of the second gear 622 through the rack 61 to rotate the head body 10 around the first axis.

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

[0084] The rack 61 has a first tooth 612 and a second tooth 613. The first tooth 612 and the second tooth 613 respectively mesh with two sets of second cylindrical teeth. The first tooth 612 and the second tooth 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 teeth. The strip-shaped opening 614 communicates with the mounting part 131.

[0085] Understandably, the first tooth 612 meshes with the second cylindrical tooth on one side of the second gear 622, and the second tooth 613 meshes with the second cylindrical tooth 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 on the one hand, and allow the line 40 to pass through on the other hand, so as to extend into the head body 10.

[0087] In some embodiments, the mounting support 20 has an arc-shaped mating surface 22, the axis of which is a first axis. The head body 10 engages with the arc-shaped mating surface 22 through the mounting part 131 and can slide along the arc-shaped mating surface 22 to rotate around the first axis.

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

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

[0090] Please refer to the following: Figure 16 Specifically, the mounting bracket 20 includes a bracket body 23, a housing 24, and a limiting cover (not shown). The bracket body 23 forms an arc-shaped mating surface 22. The housing 24 is mounted on the first rotating seat 31 and can be connected to the first rotating seat 31 by screws. The top of the housing 24 has a mounting groove 241, and the bracket body 23 is disposed in the mounting groove 241. The top of the bracket body 23 can pass through the rack 61 via a strip-shaped opening 614 and engage with the mounting part 131. In addition, the top of the housing 24 can also form a gear groove 242, and a second gear 622 is installed in the gear groove 242. The limiting cover is disposed on the arc-shaped mating surface 22 of the bracket body 23, and the mounting part 131 is at least partially located between the bracket body 23 and the limiting cover to limit the mounting part 131 between the two and prevent the machine head body 10 from detaching.

[0091] Furthermore, the mounting support 20 also includes a support roller 25, the axis of which is parallel to the first axis. The support roller 25 is located on the support body 23 and at the arc-shaped mating surface 22, and the rolling support mounting part 131.

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

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

[0094] Please refer to the following: Figure 17 and Figure 18 In some embodiments, the drive shaft of the oscillating motor 50 includes a first drive shaft 52 and a second drive shaft 53. The first drive shaft 52 is connected to the head body 10, and the second drive shaft 53 is anti-rotationally engaged with the second rotating seat 32 in the rotation around the second axis.

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

[0096] The second drive shaft 53 is anti-rotationally engaged with the second rotating seat 32. Since the second rotating seat 32 is fixed on the body rod 211, when the second drive shaft 53 outputs torque, a reaction force is generated, which drives the oscillating motor 50 to rotate the first rotating seat 31, thereby driving the assembly support 20 and the head body 10 to rotate around the second axis.

[0097] Thus, the oscillating motor 50 can drive the up-and-down oscillation and the left-and-right oscillation respectively through two drive shafts.

[0098] Furthermore, the end section of the second drive shaft 53 is non-circular, and the second rotary seat 32 has a mating shaft hole 321 that mates with the end of the second drive shaft 53. Understandably, the mating shaft hole 321 is non-circular and mates with 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 both the first drive shaft 52 and the second drive shaft 53 can be flat. Correspondingly, the mating shaft hole 321 is also flat. Similarly, the drive gear 51 has a flat shaft hole, and the end of the first drive shaft 52 is inserted into the shaft hole of the drive gear 51 to achieve a non-rotational fit between the two.

[0100] Thus, by inserting the end of the second drive shaft 53 into the mating shaft hole 321, a non-rotational fit can be achieved between the second drive shaft 53 and the second rotating seat 32.

[0101] Furthermore, the first rotating seat 31 has a rotating shaft structure 314 extending along the direction of the second axis, and the second rotating seat 32 has a rotating groove 322 that mates with the rotating shaft structure 314. One of the rotating shaft structure 314 and the rotating groove 322 has a latch 323 (e.g., ...). Figure 3 As shown), the other has a slot 3141, which engages with the buckle 323 and creates 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 mating shaft hole 321, and the second drive shaft 53 passes through the rotating shaft structure 314 and mates with the mating shaft hole 321.

[0103] Thus, the first rotating seat 31 can rotate and engage with the second rotating seat 32 around the second axis through the rotating shaft structure 314, and the engagement of the buckle 323 and the slot 3141 can reduce the probability of abnormal disengagement between the two.

[0104] Furthermore, the surface of the second rotating seat 32 that mates 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 rotation of the first rotating seat 31.

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

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

[0107] Thus, when the head shaking is not required, the transmission gear 62 can be controlled to be in a non-transmission state by the clutch mechanism, so that the head shaking motor 50 can no longer drive the head body 10 to rotate around the first axis through the transmission mechanism.

[0108] The aforementioned head assembly 100 includes a sway motor 50 mounted on a first rotating base 31. The sway motor 50 has a first drive shaft 52 and a second drive shaft 53. A drive gear 51 is mounted on the first drive shaft 52, meshing with a first gear 621. The first gear 621 is a two-stage compound gear; the first stage consists of a first cylindrical tooth portion meshing with the drive gear 51, and the second stage consists of a first conical tooth portion meshing 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 a second bevel gear, and the second stage consists of second cylindrical teeth on both sides. The second cylindrical teeth on both sides of the second gear 622 mesh with a rack 61, which is fixed to the head body 10.

[0109] When the oscillating motor 50 operates, the first drive shaft 52 drives the drive gear 51, which in turn drives the first gear 621, then the second gear 622, and finally the rack 61, completing the up-and-down oscillating motion of the entire machine. The second drive shaft 53 for oscillation is inserted into the mating shaft hole 321 of the second rotating seat 32, directly driving the first rotating seat 31 and the parts mounted on the first rotating shaft to rotate together through the reaction force, completing the left-and-right oscillating motion. The first rotating seat 31 is provided with a second wire passage 311, and the mounting support 20 is provided with a first wire passage 21. This mounting support 20 passes through the rack 61 and is fixed to the outer casing 24 by screws. The wire 40 passes through the second wire passage 311 of the first rotating seat 31 from bottom to top, vertically upwards, and then through the first wire passage 21 of the mounting support 20 to reach the machine head body 10. This section of the journey from the second wire passage 311 to the first wire passage 21 is independent of the transmission gear 62 and is not affected by the movement of the transmission gear 62. Next, the wire 40 follows the curvature of the mounting portion 131 of the head body 10, and the wire 40 located within the mounting portion 131 is a spring wire 41. The wire 40 passes through the wire hole of the head body 10, and the terminal of the wire 40 is plugged into the control board. Therefore, when the oscillation is activated, regardless of whether the head body 10 swings up and down or left and right, the entire length of the wire 40 will not be pulled or bent back and forth. The wire 40 is in a naturally straight state when oscillating. Only when oscillating up and down, due to the relative movement between the head body 10 and the outer casing 24, there will be slight pulling at the junction of the head body 10 and the mounting bracket 20. However, the elasticity of the spring wire 41 can resist the slight pulling force when oscillating up and down. The relative movement of the internal wire core is small, which helps to extend the service life of the wire 40.

[0110] In addition, the length of the line 40 can be increased according to the relative movement of the up and down oscillation. When the up and down oscillation is not activated, the excess length of the line 40 is placed in the wire passage of the head body 10. When the up and down oscillation reaches its limit position, the line 40 unfolds and will not be excessively stretched.

[0111] Thus, the head assembly 100 can simultaneously drive the head body 10 to oscillate up and down and left and right via the oscillating motor 50, reducing both the number of parts and the number of wires 40. Furthermore, both the oscillating motor 50 and the mounting support 20 are mounted on the first rotating base 31 and rotate accordingly. The wires 40 pass through the wire channels on the mounting support 20 and the first rotating base 31, extending into the mounting portion 131 to connect to the head body 10. The wires 40 located in the mounting portion 131 are spring wires 41. Therefore, when the head assembly 100 performs large-angle, multi-directional oscillating movements, the bending and pulling of the wires 40 are minimal, the wiring is simple and reliable, and this helps to improve the lifespan of the wiring during long-term oscillating operation.

[0112] This application also provides a fan 200, including the aforementioned head assembly 100. It can be understood that, in order to achieve its normal function, the fan 200 also includes a body assembly 210, to which the head assembly 100 is connected.
