Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a telescopic oscillating mechanism and a fan. Background Technology

[0002] Circulating fans typically include a lifting mechanism and a left-right oscillation mechanism. The lifting mechanism can adjust the height of the fan head. A common solution in related technologies is that the lifting mechanism includes a support rod, and the left-right oscillation mechanism is located at the top of the support rod and connected to the fan head. This results in a relatively thick structure at the top of the support rod, making the circulating fan appear bulky and affecting the product's aesthetics and user experience. Utility Model Content

[0003] This utility model provides a telescopic oscillating mechanism and a fan to solve the problem in related technologies where the left and right oscillating mechanism is located at the top of the support rod, resulting in a relatively thick structure at the top of the support rod.

[0004] In a first aspect, this utility model provides a telescopic head-shaking mechanism, comprising: A lifting boom, the top of which is adapted to connect to the machine head; A support base, including an outer tube, wherein the lifting rod is adapted to move up and down relative to the outer tube; A fixing component is provided at the top of the outer tube, and the lifting rod extends into the outer tube through the fixing component; A locking structure is provided on the fixing component, the locking structure being adapted to lock and unlock the position of the lifting rod; A left and right oscillating assembly is connected to the lifting rod, and the left and right oscillating assembly is located inside the outer tube.

[0005] Beneficial effects: The top of the lifting rod is suitable for connecting to the machine head, and the lifting rod is suitable for lifting and lowering relative to the outer tube. Therefore, when the lifting rod is raised and lowered, it will drive the machine head to rise and fall together, thereby achieving adjustment of the height of the machine head. The fixing component is located at the top of the outer tube, and the locking structure is located at the fixing component. The locking structure is suitable for locking and unlocking the position of the lifting rod. When the locking structure locks the position of the lifting rod, the lifting rod cannot be raised or lowered, thus fixing the height of the machine head. When the locking structure unlocks the position of the lifting rod, the lifting rod can be raised and lowered. By connecting the left and right oscillating components to the lifting rod, the lifting rod will synchronously drive the left and right oscillating components to rise and fall together when it is raised and lowered. When the left and right oscillating components are working, they can drive the lifting rod to rotate, thereby causing the machine head to oscillate left and right. Since the left and right oscillating components are located inside the outer tube, compared with related technologies, the left and right oscillating components do not need to occupy the space at the top of the lifting rod, which can reduce the structure at the top of the lifting rod, improve the aesthetics of the product, and make full use of the internal space of the outer tube by placing the left and right oscillating components inside the outer tube.

[0006] In one optional implementation, the left and right head-shaking component includes: The motor cover is fixedly connected to the lifting rod. A oscillating motor is fixed to the motor cover, and the output shaft of the oscillating motor is connected to a drive gear; The sleeve is provided with a driven gear that meshes with the driving gear. The sleeve is vertically and vertically disposed inside the outer tube, and the sleeve is fixed relative to the outer tube in the circumferential direction.

[0007] Beneficial effects: The oscillating motor is connected to a drive gear. When the oscillating motor is working, it drives the drive gear to rotate. The sleeve is equipped with a driven gear, which meshes with the drive gear. Therefore, the drive gear drives the driven gear, which in turn drives the sleeve to rotate. Since the sleeve is fixed relative to the outer tube in the circumferential direction and the outer tube is fixed, the sleeve cannot rotate. The position of the driven gear is fixed, which causes the oscillating motor, the drive gear, and the sleeve to rotate relative to each other. The oscillating motor is fixed to the motor cover, and the motor cover is fixedly connected to the lifting rod. Therefore, when the oscillating motor rotates relative to the sleeve, it drives the motor cover and the lifting rod to rotate synchronously, thereby realizing the left and right oscillation of the machine head.

[0008] In one optional embodiment, the outer wall of the sleeve is provided with one of a limiting groove and a limiting rib, and the inner wall of the outer tube is provided with the other of a limiting groove and a limiting rib. The limiting rib is slidably disposed in the limiting groove, and the limiting groove extends in a vertical direction.

[0009] Beneficial effects: By providing one of a limiting groove and a limiting rib on the outer wall of the sleeve, and the other of a limiting groove and a limiting rib on the inner wall of the outer tube, and the limiting rib being slidably provided in the limiting groove, which extends vertically, the sleeve can be fixed relative to the outer tube in the circumferential direction, and the sleeve cannot rotate relative to the outer tube. At the same time, the sleeve can move up and down relative to the outer tube.

[0010] In one optional embodiment, the left and right swaying assembly further includes a rotating component, which is fixedly connected to the swaying motor and / or the motor cover, and is rotatably connected to the sleeve.

[0011] Beneficial effects: The rotating part is fixedly connected to the oscillating motor and / or motor cover. When the oscillating motor oscillates left and right, the rotating part rotates together with the oscillating motor. The rotating part is rotatably connected to the sleeve, which can ensure that the oscillating motor and motor cover rotate smoothly relative to the sleeve.

[0012] In one alternative embodiment, the rotating member has one of a shaft hole and a rotating shaft, and the sleeve has the other of a shaft hole and a rotating shaft, the rotating shaft being rotatably disposed in the shaft hole.

[0013] Beneficial effects: The rotating part has one of a shaft hole and a rotating shaft, and the sleeve has the other of a shaft hole and a rotating shaft. The rotating shaft is rotatably located in the shaft hole. The cooperation between the rotating shaft and the shaft hole allows the rotating part to rotate relative to the sleeve, and also allows for positioning of the assembly between the rotating part and the sleeve, thereby improving assembly efficiency.

[0014] In one optional embodiment, the rotating shaft is provided with a first connecting post, one end of the shaft hole is provided with a first through hole, the first connecting post passes through the first through hole and is rotatably disposed in the first through hole, and a limiting member is provided at the end of the first connecting post near the first through hole. On a projection plane perpendicular to the axial direction of the first connecting post, the maximum outer diameter or maximum width of the limiting member is greater than the diameter of the first through hole.

[0015] Beneficial effects: The first connecting post passes through the first through hole and can rotate within the first through hole, thereby enabling the rotating part to rotate relative to the sleeve. The limiting member is located at the end of the first connecting post near the first through hole, and on the projection plane perpendicular to the axial direction of the first connecting post, the maximum outer diameter or maximum width of the limiting member is greater than the diameter of the first through hole. The limiting member can restrict the rotating part from moving along the axial direction.

[0016] In one alternative embodiment, the rotating member is provided with a gear groove, and the driving gear is disposed in the gear groove.

[0017] Beneficial effect: By setting gear grooves in the rotating parts, it is convenient to install and position the drive gear.

[0018] In one optional embodiment, the motor cover is provided with a first wire passage hole, the rotating component is provided with a second wire passage hole, and the internal wiring connected to the machine head is adapted to pass through the lifting rod, the first wire passage hole and the second wire passage hole in sequence. And / or, the motor wire connected to the oscillating motor is adapted to pass through the first wire hole, and the lifting rod is connected to the control board located at the machine head, or the motor wire connected to the oscillating motor is adapted to pass through the first wire hole, and the lifting rod is connected to the control board located at the lifting rod.

[0019] Beneficial effects: By setting the first wire passage hole in the motor cover and the second wire passage hole in the rotating part, it is convenient to route the internal wiring and the motor wires.

[0020] In one alternative embodiment, the sleeve is provided with a third wire passage hole, through which the internal wiring is adapted to pass.

[0021] Beneficial effect: By setting a third wire passage hole on the sleeve, it is easier to route the internal wiring.

[0022] In one optional implementation, the telescopic oscillating mechanism further includes: An adapter is fixed to the sleeve, and the adapter is provided with a wiring port, through which the internal wiring is connected; The power cord has one end connected to the terminal block and the other end adapted to pass through the support base and connect to the power source.

[0023] Beneficial effects: The adapter is equipped with a wiring port, and the internal wiring is connected to the wiring port. One end of the power cord is connected to the wiring port, and the other end is suitable for passing through the support base and connecting to the power supply. Therefore, the electrical connection between the internal wiring and the power cord can be ensured. Furthermore, during the lifting process of the lifting rod, the adapter is raised and lowered along with it, and the power cord is extended or compressed, so the internal wiring will not be pulled.

[0024] In one alternative embodiment, the sleeve is further provided with a wire fixing structure, to which a portion of the power cord is fixed.

[0025] Beneficial effect: By setting a wire fixing structure on the sleeve, part of the power cord is fixed to the wire fixing structure, which can prevent the power cord from separating from the terminal when it is extended or retracted.

[0026] In one alternative implementation, the fixing component includes: The upper cover has a first through hole through which the lifting rod passes. The locking structure is adapted to pass through the upper cover and abut against the lifting rod. The upper cover is fixed relative to the outer tube.

[0027] In one alternative implementation, the fixing component further includes: A connector is provided with a second through hole through which the lifting rod passes. The connector is fixed to the upper cover and supported at the top of the outer tube.

[0028] Beneficial effects: The fixing components include a top cover and a connector, which can be fixedly connected to the top cover after the locking structure is assembled with the top cover.

[0029] In one optional embodiment, the upper cover is provided with an assembly groove, the upper cover includes an outer ring wall and an inner ring wall, the inner side of the inner ring wall forms the first through hole, the outer ring wall is provided with a first mounting hole, and the inner ring wall is provided with a second mounting hole; The locking structure includes a knob rod, a mating part threadedly connected to the knob rod, and a locking part fixed to one end of the knob rod. The knob rod passes through the first mounting hole, the mating part is confined within the assembly groove, and the locking part is adapted to abut against the lifting rod.

[0030] Beneficial effects: The knob rod passes through the first mounting hole, and the mating part is confined in the assembly groove. Since the mating part is threadedly connected to the knob rod, when the knob rod is rotated, the knob rod moves relative to the mating part, thereby driving the locking part to move. This causes the locking part to move towards the lifting rod or away from the lifting rod, thereby locking or unlocking the lifting rod, which is convenient for user operation.

[0031] Secondly, this utility model also provides a fan, including a fan head and the telescopic oscillating mechanism, wherein the fan head is connected to the top end of the lifting rod.

[0032] Beneficial effects: This fan features a lifting rod that is adapted to rise and fall relative to the outer tube. Therefore, when the lifting rod rises and falls, it drives the fan head to rise and fall together, thus adjusting the height of the fan head. A fixing component is located at the top of the outer tube, and a locking structure is located within the fixing component. The locking structure is suitable for locking and unlocking the position of the lifting rod. When the locking structure locks the position of the lifting rod, the lifting rod cannot be adjusted, thus fixing the height of the fan head. When the locking structure unlocks the position of the lifting rod, the lifting rod can be adjusted. By connecting the left and right oscillation components to the lifting rod, the lifting rod synchronously drives the left and right oscillation components to rise and fall together. When the left and right oscillation components are working, they can drive the lifting rod to rotate, thereby causing the fan head to oscillate left and right. Since the left and right oscillation components are located inside the outer tube, compared with related technologies, the left and right oscillation components do not need to occupy the space at the top of the lifting rod, allowing for a thinner structure at the top of the lifting rod, improving the product's aesthetics. Furthermore, placing the left and right oscillation components inside the outer tube makes full use of the space inside the outer tube. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0040] Circulating fans typically include a lifting mechanism and a left-right oscillation mechanism. The lifting mechanism can adjust the height of the fan head. A common solution in related technologies is that the lifting mechanism includes a support rod, and the left-right oscillation mechanism is located at the top of the support rod and connected to the fan head. This results in a relatively thick structure at the top of the support rod, making the circulating fan appear bulky and affecting the product's aesthetics and user experience.

[0041] The following is combined Figures 1 to 21 The following describes embodiments of the present invention.

[0042] According to an embodiment of the present invention, a telescopic swaying mechanism is provided, comprising: a lifting rod 1, a support base 3, a fixing component, a locking structure 14, and a left and right swaying component.

[0043] The lifting rod 1 is adapted to connect to the machine head 2 at its top; the support base 3 includes an outer tube 301, and the lifting rod 1 is adapted to lift relative to the outer tube 301; a fixing component is located at the top of the outer tube 301, and the lifting rod 1 extends into the outer tube 301 through the fixing component; a locking structure 14 is located on the fixing component, and the locking structure 14 is adapted to lock and unlock the position of the lifting rod 1; a left and right swaying component is connected to the lifting rod 1, and the left and right swaying component is located inside the outer tube 301.

[0044] In this embodiment, the top of the lifting rod 1 is adapted to connect to the machine head 2, and the lifting rod 1 is adapted to rise and fall relative to the outer tube 301. Therefore, when the lifting rod 1 rises and falls, it will drive the machine head 2 to rise and fall together, thereby realizing the adjustment of the height of the machine head 2. The fixing component is provided at the top of the outer tube 301, and the locking structure 14 is provided at the fixing component. The locking structure 14 is adapted to lock and unlock the position of the lifting rod 1. When the locking structure 14 locks the position of the lifting rod 1, the lifting rod 1 cannot be adjusted up and down, thus fixing the height of the machine head 2. When the locking structure 14 unlocks the position of the lifting rod 1, the lifting rod 1 can be adjusted up and down. By connecting the left and right oscillating components to the lifting rod 1, the lifting rod 1 can simultaneously drive the left and right oscillating components to rise and fall together when it is raised and lowered. When the left and right oscillating components are working, they can drive the lifting rod 1 to rotate, thereby causing the machine head 2 to oscillate left and right. Since the left and right oscillating components are located inside the outer tube 301, compared with related technologies, the left and right oscillating components do not need to occupy the space at the top of the lifting rod 1, which can reduce the structure at the top of the lifting rod 1, improve the aesthetics of the product, and by placing the left and right oscillating components inside the outer tube 301, the internal space of the outer tube 301 can be fully utilized.

[0045] In one specific embodiment, the support base 3 further includes a chassis 302, and the outer tube 301 is fixed on the chassis 302.

[0046] Specifically in one embodiment, such as Figure 1 As shown, the lifting rod 1 includes a vertically arranged vertical rod segment 101 and an inclined rod segment 102 located at the top of the vertical rod segment 101. The top of the inclined rod segment 102 is connected to the machine head 2 through a connector 13, which can make the center of gravity of the machine head 2 collinear with the center of gravity of the vertical rod, making the structure more stable.

[0047] In one embodiment, the left and right swaying assembly includes a motor cover 4, a swaying motor 5, and a sleeve 7. The motor cover 4 is fixedly connected to the lifting rod 1; the swaying motor 5 is fixed to the motor cover 4, and the output shaft of the swaying motor 5 is connected to a drive gear 6; the sleeve 7 is provided with a driven gear, which meshes with the drive gear 6; the sleeve 7 is vertically and vertically disposed within the outer tube 301, and the sleeve 7 is fixed relative to the outer tube 301 in the circumferential direction.

[0048] In this embodiment, the oscillating motor 5 is connected to the driving gear 6. When the oscillating motor 5 is working, it drives the driving gear 6 to rotate. The sleeve 7 is provided with a driven gear, which meshes with the driving gear 6. Therefore, the driving gear 6 drives the driven gear and thus drives the sleeve 7 to rotate. Since the sleeve 7 is fixed relative to the outer tube 301 in the circumferential direction and the outer tube 301 is fixedly set, the sleeve 7 cannot rotate. The position of the driven gear is fixed, thereby causing the oscillating motor 5, the driving gear 6, and the sleeve 7 to rotate relative to each other. The oscillating motor 5 is fixed to the motor cover 4, and the motor cover 4 is fixedly connected to the lifting rod 1. Therefore, when the oscillating motor 5 rotates relative to the sleeve 7, it drives the motor cover 4 and the lifting rod 1 to rotate synchronously, thereby realizing the left and right oscillation of the machine head 2.

[0049] In one specific embodiment, the oscillating motor 5 is eccentrically positioned, and the axis of the driven gear coincides with the central axis of the sleeve 7. Therefore, the oscillating motor 5 and the driving gear 6 will rotate around the driven gear.

[0050] Specifically, the oscillating motor 5 can work in both forward and reverse directions. When it is necessary to oscillate left and right, the oscillating motor 5 is controlled to work in both forward and reverse directions periodically. The driven gear is an incomplete gear, which can realize the oscillating motor 5 and the driving gear 6 oscillating back and forth relative to the driven gear, thereby realizing the left and right oscillation.

[0051] In one specific embodiment, the motor cover 4 is provided with a slot 401, and the lifting rod 1 is inserted into the slot 401 and fixedly connected to the motor cover 4.

[0052] More specifically, such as Figure 14 As shown, the motor cover 4 includes a first annular wall 402, a second annular wall 403, and a third annular wall 404 coaxially arranged. The third annular wall 404 is located on the outermost side, and the first annular wall 402 is located on the innermost side. A slot 401 is formed between the first annular wall 402 and the second annular wall 403. The lifting rod 1 is a hollow tubular structure, and the lower end of the lifting rod 1 is inserted into the slot 401. The cooperation between the first annular wall 402 and the second annular wall 403 can prevent the lifting rod 1 from shaking. The second annular wall 403 is provided with a first screw through hole 4031, such as... Figure 10 As shown, the lifting rod 1 is provided with a second screw through hole 103, and the first annular wall 402 is provided with a first screw hole 4021. The fastener passes through the first screw through hole 4031 and the second screw through hole 103 and is screwed into the first screw hole 4021 to fix the lifting rod 1 to the motor cover 4.

[0053] In one embodiment, the outer wall of the sleeve 7 is provided with one of a limiting groove 701 and a limiting rib 3011, and the inner wall of the outer tube 301 is provided with the other of a limiting groove 701 and a limiting rib 3011. The limiting rib 3011 is slidably provided in the limiting groove 701, and the limiting groove 701 extends in the vertical direction.

[0054] In this embodiment, by providing one of a limiting groove 701 and a limiting rib 3011 on the outer wall of the sleeve 7, and the other of a limiting groove 701 and a limiting rib 3011 on the inner wall of the outer tube 301, the limiting rib 3011 is slidably provided in the limiting groove 701, and the limiting groove 701 extends in the vertical direction, so that the sleeve 7 can be fixed relative to the outer tube 301 in the circumferential direction, and the sleeve 7 cannot rotate relative to the outer tube 301. At the same time, the sleeve 7 can move up and down relative to the outer tube 301.

[0055] Specifically in one embodiment, such as Figure 17 As shown, the outer wall of the sleeve 7 is provided with a limiting groove 701, such as Figure 19 As shown, the inner wall of the outer tube 301 is provided with a limiting rib 3011.

[0056] In one embodiment, the left and right swaying assembly further includes a rotating component 8, which is fixedly connected to the swaying motor 5 and / or the motor cover 4, and is rotatably connected to the sleeve 7.

[0057] In this embodiment, the rotating component 8 is fixedly connected to the oscillating motor 5 and / or the motor cover 4. When the oscillating motor moves left and right, the rotating component 8 rotates together with the oscillating motor 5. The rotating component 8 is rotatably connected to the sleeve 7, which can ensure that the oscillating motor 5 and the motor cover 4 rotate smoothly relative to the sleeve 7.

[0058] Specifically in one embodiment, such as Figures 14 to 16 The rotating component 8 is provided with a third screw through hole 801, the oscillating motor 5 is provided with a fourth screw through hole 501, and the motor cover 4 is provided with a first screw post 405. The fastener passes through the third screw through hole 801 and the fourth screw through hole 501 and is screwed into the first screw post 405 to connect the motor cover 4, the oscillating motor 5 and the rotating component 8 together.

[0059] In one embodiment, the rotating member 8 is provided with one of a shaft hole 702 and a rotating shaft 802, and the sleeve 7 is provided with the other of a shaft hole 702 and a rotating shaft 802, with the rotating shaft 802 rotatably disposed in the shaft hole 702.

[0060] In this embodiment, the rotating component 8 is provided with one of a shaft hole 702 and a rotating shaft 802, and the sleeve 7 is provided with the other of a shaft hole 702 and a rotating shaft 802. The rotating shaft 802 is rotatably disposed in the shaft hole 702. The cooperation between the rotating shaft 802 and the shaft hole 702 allows the rotating component 8 to rotate relative to the sleeve 7, and also allows for positioning of the assembly between the rotating component 8 and the sleeve 7, thereby improving assembly efficiency.

[0061] Specifically in one embodiment, such as Figure 16 As shown, the rotating component 8 is provided with a rotating shaft 802, such as Figure 17 As shown, sleeve 7 is provided with shaft hole 702.

[0062] In one embodiment, the rotating shaft 802 is provided with a first connecting post 803, and one end of the shaft hole 702 is provided with a first through hole 703. The first connecting post 803 passes through the first through hole 703 and is rotatably disposed in the first through hole 703. A limiting member is provided at the end of the first connecting post 803 near the first through hole 703. On a projection plane perpendicular to the axial direction of the first connecting post 803, the maximum outer diameter or maximum width of the limiting member is greater than the diameter of the first through hole 703.

[0063] In this embodiment, the first connecting post 803 passes through the first through hole 703 and can rotate within the first through hole 703, thereby enabling the rotating member 8 to rotate relative to the sleeve 7. The limiting member is provided at the end of the first connecting post 803 near the first through hole 703. On the projection plane perpendicular to the axial direction of the first connecting post 803, the maximum outer diameter or maximum width of the limiting member is greater than the diameter of the first through hole 703. The limiting member can restrict the rotating member 8 from moving along the axial direction.

[0064] Specifically, the first connecting post 803 passes through the first through hole 703 and has a gap with the first through hole 703.

[0065] In one specific embodiment, the first connecting post 803 has a connecting hole 8031, and the limiting member is specifically a screw. The shank of the screw is screwed into and fixed in the connecting hole 8031, and the screw nut is located at the end of the first connecting post 803, and the maximum outer diameter of the nut is larger than the diameter of the first through hole 703. In an alternative embodiment, the limiting member can be an elastic snap-fit ​​member disposed at the end of the first connecting post 803. When the first connecting post 803 is installed into the first through hole 703, the elastic snap-fit ​​member is subjected to force and contracts towards the central axis of the first connecting post 803. After the elastic snap-fit ​​member passes through the first through hole 703, the first elastic snap-fit ​​member rebounds away from the central axis of the first connecting post 803, so that the elastic snap-fit ​​member is limited to the bottom wall where the first through hole 703 is located.

[0076] In this embodiment, the adapter 10 is provided with a wiring port 1001, the internal wiring 9 is connected to the wiring port 1001, one end of the power cord 11 is connected to the wiring port 1001, and the other end is adapted to pass through the support base 3 and connect to the power supply. Therefore, the electrical connection between the internal wiring 9 and the power cord 11 can be ensured. Furthermore, during the lifting process of the lifting rod 1, the adapter 10 is lifted and lowered along with it, and the internal wiring 9 will not be pulled.

[0077] In one embodiment, at least a portion of the power cord 11 is elastic. During the lifting process of the lifting rod 1, the adapter 10 rises and falls with it, and the power cord 11 extends or compresses, ensuring that the power cord 11 can be stably connected to the connection port 1001.

[0078] In one specific embodiment, the adapter 10 is connected to the sleeve 7 by screws.

[0079] Specifically, such as Figure 18 and Figure 19 The adapter 10 is provided with a second screw post 1002, and the sleeve 7 is provided with a fifth screw hole 705. After the screw passes through the fifth screw hole 705, it is screwed into the second screw post 1002 to achieve a fixed connection between the adapter 10 and the sleeve 7.

[0080] In one specific embodiment, the adapter 10 is a gravity ball, and the adapter 10 itself is a tilt switch. When the fan tilts, the tilt switch is turned off, and the fan is automatically powered off.

[0081] In one embodiment, the sleeve 7 is further provided with a wire fixing structure 706, to which a portion of the power line 11 is fixed.

[0082] In this embodiment, by providing a wire fixing structure 706 on the sleeve 7, a portion of the power cord 11 is fixed to the wire fixing structure 706, which can prevent the power cord 11 from separating from the connection port 1001 when it is extended or retracted.

[0083] In one specific embodiment, the first end of the power cord 11 is connected to the connector 1001, and the portion of the power cord 11 near its first end is fixed to the wire fixing structure 706.

[0084] In one embodiment, the fixing component includes an upper cover 12, which has a first through hole 1201 through which the lifting rod 1 passes. The locking structure 14 is adapted to pass through the upper cover 12 and abut against the lifting rod 1. The upper cover 12 is fixed relative to the outer tube 301.

[0085] In this embodiment, the fixing component includes an upper cover 12, which is fixed relative to the outer tube 301. Therefore, the upper cover 12 remains stationary and can close the top of the outer tube 301, resulting in a more aesthetically pleasing appearance.

[0086] In one embodiment, the fixing component further includes a connector 13, which has a second through hole 1301 through which the lifting rod 1 passes. The connector 13 is fixed to the upper cover 12 and supported on the top of the outer tube 301.

[0087] In this embodiment, the fixing component includes an upper cover 12 and a connector 13, which can be fixedly connected to the upper cover 12 after the locking structure 14 is assembled with the upper cover 12.

[0088] Specifically, the connector 13 is fixed to the top cover 12 and supported at the top of the outer tube 301, so the fixing component will not rise or fall with the lifting rod 1, nor will it rotate with the lifting rod 1.

[0089] Specifically in one embodiment, such as Figure 3 As shown, the top end of the outer tube 301 is provided with a first mating surface 3012, and the connector 13 is provided with a second mating surface 1302. The first mating surface 3012 and the second mating surface 1302 are both horizontally arranged. The first mating surface 3012 and the second mating surface 1302 abut against each other and are both friction surfaces.

[0090] Specifically in one embodiment, such as Figure 13 As shown, connector 13 is provided with a sixth screw hole 1303, as... Figure 11 As shown, the upper cover 12 is provided with a third screw post 1202. After the screw passes through the sixth screw hole 1303, it is screwed into the third screw post 1202 to achieve a fixed connection between the connector 13 and the upper cover 12.

[0091] In one embodiment, combined Figure 3 , Figure 11 and Figure 12 The upper cover 12 is provided with an assembly groove 1203. The upper cover 12 includes an outer ring wall and an inner ring wall. The inner side of the inner ring wall forms a first through hole 1201. The outer ring wall is provided with a first mounting hole 1205. The inner ring wall is provided with a second mounting hole 1206. The locking structure 14 includes a knob rod 1401, a mating part 1402 threadedly connected to the knob rod 1401, and a locking part 1403 fixed to one end of the knob rod 1401. The knob rod 1401 passes through the first mounting hole 1205. The mating part 1402 is confined within the assembly groove 1203. The locking part 1403 is adapted to abut against the lifting rod 1.

[0092] In this embodiment, the knob rod 1401 passes through the first mounting hole 1205, and the mating part 1402 is confined within the assembly groove 1203. Since the mating part 1402 is threadedly connected to the knob rod 1401, when the knob rod 1401 is rotated, the knob rod 1401 moves relative to the mating part 1402, thereby driving the locking part 1403 to move. This causes the locking part 1403 to move towards the lifting rod 1 or away from the lifting rod 1, thereby locking or unlocking the lifting rod 1 for user operation.

[0093] In one specific embodiment, a knob 1404 is provided at one end of the knob lever 1401 for easy operation by the user.

[0094] In one specific embodiment, the end of the locking part 1403 is a friction surface that makes frictional contact with the lifting rod 1, thereby locking the lifting rod 1 using frictional force.

[0095] Specifically in one embodiment, such as Figure 3 and Figure 7As shown, the motor cover 4 is provided with a first limiting end face 407, and the upper cover 12 is provided with a second limiting end face 1204. When the lifting rod 1 rises to the highest position, the first limiting end face 407 abuts against the second limiting end face 1204, and the second limiting end face 1204 prevents the lifting rod 1 from continuing to rise.

[0096] In one specific embodiment, the sleeve 7 has a protrusion 707, and the chassis 302 includes a base plate 3021, such as Figure 5 As shown, when the lifting rod 1 is lowered to its lowest position, the protrusion 707 abuts against the base plate 3021, preventing the lifting rod 1 from descending further. When the lifting rod 1 is lowered to its lowest position, the height between the lower end of the adapter 10 and the base plate 3021 is H, which is approximately 100 mm, providing space for the power cord 11.

[0097] The specific assembly process of the telescopic swing mechanism provided in this embodiment is as follows: First, assemble the mating part 1402 in the locking structure 14 into the mounting groove 1203 of the upper cover 12. Then, pass the knob rod 1401 through the first mounting hole 1205 and through the mating part 1402 to fix the locking part 1403 to the end of the knob rod 1401. Next, pass the fastener through the sixth screw hole 1303 of the connector 13 and screw it into the third screw post 1202 of the upper cover 12 to achieve a fixed connection between the connector 13 and the upper cover 12. Then, pass the lifting rod 1 through the first through hole 1201 of the upper cover 12 and the second through hole 1301 of the connector 13, insert the lifting rod 1 into the slot 401 of the motor cover 4, and pass the fastener through the first screw through hole 4031 of the motor cover 4 and the second screw through hole 103 of the lifting rod 1 and screw it into the first screw hole 4021 of the motor cover 4 to achieve a fixed connection between the lifting rod 1 and the motor cover 4. Next, the oscillating motor 5 is assembled onto the motor cover 4, and the rotating component 8 is assembled onto the motor cover 4. The rotating component 8 has a third screw through hole 801, the oscillating motor 5 has a fourth screw through hole 501, and the motor cover 4 has a first screw post 405. The fastener passes through the third screw through hole 801 of the rotating component 8 and the fourth screw through hole 501 of the oscillating motor 5 and is screwed into the first screw post 405 of the motor cover 4, thereby connecting the motor cover 4, the oscillating motor 5 and the rotating component 8 together. At the same time, the drive gear 6 is assembled into the gear groove 804 of the rotating component 8. At this time, the internal wiring 9 passes out from the lifting rod 1 and passes through the first wiring hole 406 of the motor cover 4 and the second wiring hole 805 of the rotating component 8. The motor wire 502 passes directly through the first wiring hole 406 and the lifting rod 1 and connects to the control board at the machine head 2.

[0098] Next, align the shaft hole 702 of the sleeve 7 with the rotating shaft 802 of the rotating part 8, and connect the first connecting post 803 at the center of the rotating shaft 802 and the first through hole 703 at the end of the shaft hole 702 by screwing. Then, fix the second screw post 1002 of the adapter 10 and the fifth screw hole 705 of the sleeve 7 by screwing. Then, the internal wiring 9 passes through the third wire hole 704 of the sleeve 7 and is connected to the terminal 1001. The power cord 11 passes through the chassis 302, is first fixed by the wire fixing structure 706, and then connected to the terminal 1001. Then, assemble the sleeve 7 into the outer tube 301 of the support base 3, and make the limiting groove 701 of the sleeve 7 engage with the limiting rib 3011 of the outer tube 301, and make the second mating surface 1302 of the connector 13 contact the first mating surface 3012 at the top of the outer tube 301, thereby completing the overall assembly.

[0099] According to an embodiment of the present invention, another aspect is provided: a fan including a head 2 and a telescopic oscillating mechanism provided in the above embodiment, wherein the head 2 is connected to the top end of the lifting rod 1.

[0100] The fan has a lifting rod 1 that is adapted to rise and fall relative to the outer tube 301. Therefore, when the lifting rod 1 rises and falls, it drives the fan head 2 to rise and fall together, thus adjusting the height of the fan head 2. A fixing component is located at the top of the outer tube 301, and a locking structure 14 is located on the fixing component. The locking structure 14 is adapted to lock and unlock the position of the lifting rod 1. When the locking structure 14 locks the position of the lifting rod 1, the lifting rod 1 cannot be adjusted, thus fixing the height of the fan head 2. When the locking structure 14 unlocks the position of the lifting rod 1, the lifting rod 1 can be adjusted. By connecting the left and right oscillating components to the lifting rod 1, the lifting rod 1 synchronously drives the left and right oscillating components to rise and fall together when it rises and falls. When the left and right oscillating components are working, they can drive the lifting rod 1 to rotate, thereby causing the fan head 2 to oscillate left and right. Since the left and right oscillating components are located inside the outer tube 301, compared with related technologies, the left and right oscillating components do not need to occupy the space at the top of the lifting rod 1, which can reduce the structure at the top of the lifting rod 1, improve the aesthetics of the product, and make full use of the internal space of the outer tube 301.

[0101] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
