[0002] A fan is a device that blows air into the environment, improving the ambient temperature and enhancing user comfort. Fan height typically needs to be adjustable to accommodate users of different heights or in different postures. Currently, fan height adjustment requires manual adjustment, which is time-consuming and laborious. Utility Model Content

[0003] In view of this, this application provides a fan, including an air outlet device and a lifting device, wherein the lifting device includes: Motor module; A screw is connected to the motor module, and the motor module is used to drive the screw to rotate; A mating component is threadedly connected to the screw rod, and the mating component can be fixed in place; A lifting component is connected to the screw and limited to the screw along the axial direction of the screw; the air outlet device is fixed to the lifting component. When the motor module is working, it drives the screw to rotate. The screw cooperates with the mating part to move the screw along its axial direction, thereby driving the lifting part and the motor module to move along the axial direction, and thus driving the air outlet device to rise and fall.

[0004] Based on this, the lifting device further includes a connecting member and a guide member in the same axial direction as the screw. The guide member is disposed on the periphery of the screw. The screw and the guide member are both connected to the connecting member and are limited to the connecting member in the axial direction of the screw. The guide member is also connected to the lifting member and is limited to the lifting member in the axial direction of the guide member. When the screw moves along its axial direction, the connecting member moves along the axial direction, thereby causing the guide member and the lifting member to also move along the axial direction.

[0005] Based on this, the fan also includes a base, which includes a chassis and a protective shell. The protective shell is fixed to the chassis, and the mating part is fixed to one end of the protective shell away from the chassis. The connecting part, the screw portion, and the guide portion are disposed inside the protective shell. The connecting part has a first guide portion on its periphery, and the protective shell has a second guide portion on its inner wall. The first guide portion and the second guide portion cooperate with each other to allow the connecting part to slide and connect to the protective shell.

[0006] In addition, the fan also includes a spiral cable, which is located on one side of the screw and spirally arranged along the axial direction of the screw. One end of the spiral cable is used to electrically connect to an external power source, and the other end is used to electrically connect to the motor module.

[0007] Based on this, the air outlet device has a lowest position and a highest position. When the air outlet device is in the lowest position, the spiral cable is in a stretched state.

[0008] Based on this, when the lifting device further includes a connecting member and a guide member in the same axial direction as the screw, the guide member is disposed on one side of the screw, the screw and the guide member are both connected to the connecting member and are limited to the connecting member in the axial direction of the screw, and the guide member is also connected to the lifting member and is limited to the lifting member in the axial direction of the guide member; a portion of the spiral cable is disposed within one of the guide members.

[0009] Based on this, the lifting device also includes a guide shell, which is connected to one side of the lifting member along the circumference of the lifting member, and the screw and the mating part are disposed in the guide shell; the fan also includes a base, which includes a chassis and a protective shell, the protective shell is fixed to the chassis, the guide shell is disposed in the protective shell, and the mating part is disposed in the protective shell and fixed to the chassis; When the screw moves along its axial direction, the lifting member moves along the axial direction, and the guide shell moves relative to the protective shell along the axial direction.

[0010] Based on this, the outer wall of the guide shell is provided with a third guide portion, and the inner wall of the protective shell is provided with a fourth guide portion. The third guide portion and the fourth guide portion cooperate with each other to make the guide shell slide connected to the protective shell.

[0011] In addition, the fan also includes a spiral cable, part of which is located on the inner wall of the guide housing and spirally arranged along the axial direction of the guide housing. One end of the spiral cable is used to electrically connect to an external power source, and the other end is used to electrically connect to the motor module.

[0012] Based on this, the motor module includes a motor, a first gear, and a second gear. The output shaft of the motor is connected to the first gear, the first gear is rotatably connected to the second gear, the second gear is sleeved on the screw and limited to the screw in the axial and circumferential directions, and the motor is fixed to the lifting component. Alternatively, the motor module includes a motor, a worm gear, and a worm wheel. The worm gear is connected to the output shaft of the motor, the worm wheel is connected to the worm gear, the worm wheel is sleeved on the screw and limited to the screw in the axial and circumferential directions, and the motor is fixed to the lifting component.

[0013] The fan provided in this application can be equipped with a lifting device, which includes a motor module, a screw, a mating component, and a lifting element. Specifically, the motor module can be connected to the screw and used to drive the screw to rotate. The screw is threadedly connected to the fixed mating component, so the screw can cooperate with the mating component. The screw not only rotates but also moves, that is, it can move along its own axial direction. The lifting element used to fix the air outlet device can be connected to the screw, and the lifting element is limited to the screw along its axial direction. In other words, the screw can rotate relative to the lifting element, but the screw and the lifting element can move synchronously along the axial direction. Therefore, when the screw moves along its own axial direction, it can drive the lifting element and the motor module to move synchronously in the axial direction, thereby driving the air outlet device to move up and down.

[0014] In summary, this application firstly achieves the lifting function of the air outlet device by adding a lifting device. Secondly, automatic lifting is achieved by using a motor module to drive the movement of various components, eliminating the need for manual adjustment and saving time and effort. Furthermore, the structure of the lifting device is simplified through the cooperation of the motor module, screw, mating parts, and lifting components; as long as the motor module drives the screw to rotate, the screw can drive the air outlet device to rise and fall via the lifting components.

[0044] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.

[0045] In view of this, in order to solve the above problems, this application provides a fan, which you may refer to. Figures 1-5 , Figure 1 This is a three-dimensional structural diagram of the fan at its lowest position in one embodiment of this application. Figure 2 This is a three-dimensional structural diagram of the fan at its highest position according to one embodiment of this application. Figure 3 for Figure 1 The exploded view of the fan shown. Figure 4 This is a three-dimensional structural diagram of the lifting device in one embodiment of this application. Figure 5 for Figure 4 The exploded view of the lifting device is shown. The fan 1 provided in this embodiment includes an air outlet device 10a and a lifting device 20a. The lifting device 20a includes a motor module 20, a screw 30, a mating part 40, and a lifting member 50. The screw 30 is connected to the motor module 20, and the motor module 20 drives the screw 30 to rotate. The mating part 40 is threadedly connected to the screw 30 and can be fixed in place. The lifting member 50 is connected to the screw 30 and is positioned along the axial direction of the screw 30. The air outlet device 10a is fixed to the lifting member 50.

[0046] When the motor module 20 is working, it drives the screw 30 to rotate. The screw 30 cooperates with the mating part 40 to move the screw 30 along its axial direction, thereby driving the lifting part 50 and the motor module 20 to move in the axial direction, and then driving the air outlet device 10a to rise and fall.

[0047] Fan 1 is a device that can blow air and can be used in various scenarios such as indoors and outdoors. It can improve the temperature of the external environment and enhance the overall comfort of the user. Fan 1 includes, but is not limited to, circulating fans, tower fans, etc. In this embodiment and below, only tower fans are used as an illustrative example.

[0048] The fan 1 provided in this embodiment consists of an air outlet device 10a and a lifting device 20a. The air outlet device 10a is used to blow air to the outside. Based on the air outlet principle, the air outlet device 10a includes, but is not limited to, circulating air outlet devices 10a, inertial air outlet devices 10a, centrifugal air outlet devices 10a, axial air outlet devices 10a, etc. Optionally, the air outlet device 10a can blow cold air to the outside, or it can blow hot air, or it can even spray water mist to the outside while blowing air, and the water mist will drift towards the outside environment under the action of the wind.

[0049] The lifting device 20a is mainly used to achieve the lifting function. The lifting device 20a may include a motor module 20, a screw 30, a mating part 40, and a lifting component 50. However, this does not mean that the lifting device 20a only includes the motor module 20, screw 30, mating part 40, and lifting component 50; the lifting device 20a may also include other components, such as connectors and guides. This embodiment can solve the aforementioned technical problems using only the motor module 20, screw 30, mating part 40, and lifting component 50.

[0050] The motor module 20 mainly consists of a motor. A screw 30 can be connected to the motor module 20. When the motor in the motor module 20 operates, it drives the screw 30 to rotate circumferentially. A mating part 40 is used for threaded connection with the screw 30. Specifically, the outer wall of the screw 30 has external threads, and the mating part 40 has a through hole with internal threads on its inner wall. The internal and external threads engage to achieve a threaded connection between the screw 30 and the mating part 40. Furthermore, in this embodiment and below, the mating part 40 is fixed in place; that is, the mating part 40 not only does not move itself, but also does not move when the screw 30 rotates under the drive of the motor module 20. Only the screw 30 rotates relative to the mating part 40. Therefore, in the threaded connection, the screw 30 not only rotates relative to the mating part 40, but also moves up and down relative to the mating part 40 along its axial direction. For example, when the motor rotates forward, the screw 30 rises, and when the motor rotates in reverse, the screw 30 falls.

[0051] The lifting component 50 is movably connected to the screw 30, meaning it is not fixedly connected. The lifting component 50 is only confined to the screw 30 along its axial direction. In other words, the screw 30 can rotate relative to the lifting component 50, but when the screw 30 moves up and down axially, it will cause the lifting component 50 to also move up and down axially. Furthermore, when the screw 30 and the lifting component 50 move up and down axially, they can also cause the motor module 20 to move synchronously up and down axially, ensuring that the motor module 20 and the screw 30 remain relatively stationary. This allows the motor module 20 to always drive the screw 30 to rotate, preventing the motor module 20 from separating from the screw 30.

[0052] Additionally, the air outlet device 10a can be fixed to the lifting member 50, for example, by means of a threaded connection. The air outlet device 10a can be fixed at any position on the lifting member 50; for example, it can be fixed to the top of the lifting member 50, or it can be fixed to the side of the lifting member 50. Regardless of where the air outlet device 10a is fixed to the lifting member 50, when the lifting member 50 moves up and down axially, it can drive the air outlet device 10a to move up and down axially as well, thereby raising and lowering the air outlet device 10a and changing its height.

[0053] Specifically, when the motor module 20 is working, it can drive the screw 30 to rotate. The rotating screw 30 and the fixed mating part 40 cooperate with each other to make the screw 30 move up and down along its axial direction, thereby driving the lifting part 50 and the motor module 20 to move up and down along the axial direction, and then driving the air outlet device 10a to move up and down along the axial direction, so as to realize the lifting of the air outlet device 10a.

[0054] In summary, this embodiment firstly achieves the lifting function of the air outlet device 10a by adding a lifting device 20a. Secondly, automatic lifting is achieved by the motor module 20 driving the movement of various components, eliminating the need for manual adjustment and saving time and effort. Furthermore, the structure of the lifting device 20a is simplified by the cooperation of the motor module 20, the screw 30, the mating parts 40, and the lifting parts 50. As long as the motor module 20 drives the screw 30 to rotate, the screw 30 can drive the air outlet device 10a to rise and fall via the lifting parts 50.

[0055] Optionally, the air outlet device 10a includes an air outlet module 11 and an oscillating module 12. The air outlet module 11 is used to blow air outward, and the oscillating module 12 is connected to the air outlet module 11 to rotate the air outlet module 11 in a direction perpendicular to the lifting direction, thereby changing the air outlet direction. And / or, the oscillating module 12 can also be used to rotate the air outlet module 11 in the lifting direction, thereby changing the air outlet angle.

[0056] Optionally, please refer to the following as well. Figures 6-8 , Figure 6 This is a three-dimensional structural diagram of the screw and the lifting component in one embodiment of this application. Figure 7 This is a three-dimensional structural diagram from another perspective of one embodiment of this application, showing the screw and the lifting component in action. Figure 8 for Figure 7 The diagram shows an exploded view of the screw and lifting member. The lifting device 20a also includes a first bearing 31, which is sleeved on the top of the screw 30. A first receiving groove 51 is provided on the lower surface of the lifting member 50 away from the air outlet device 10a. The upper surface of the first bearing 31 can be disposed within the first receiving groove 51 and can abut against the top wall of the first receiving groove 51. The lower surface of the first bearing 31 can abut against the protruding portion of the side wall of the screw 30. The screw 30 can penetrate the lifting member 50, and the penetrating portion of the screw 30 can be limited to above the lifting member 50 by a first E-type latch 32. Thus, when the screw 30 rises, it can push the lifting member 50 upwards through the first bearing 31; when the screw 30 descends, it can move the lifting member 50 downwards through the first E-type latch 32.

[0057] Please refer to this as well. Figures 4-5 ,as well as Figure 9 , Figure 9This is a three-dimensional structural diagram of the lifting device according to another embodiment of this application. In this embodiment, the lifting device 20a further includes a connecting member 60 and a guide member 70 in the same axial direction as the screw 30. The guide member 70 is disposed on the periphery of the screw 30. Both the screw 30 and the guide member 70 are connected to the connecting member 60 and are limited to the connecting member 60 along the axial direction of the screw 30. The guide member 70 is also connected to the lifting member 50 and is limited to the lifting member 50 along the axial direction of the guide member 70. When the screw 30 moves along its axial direction, the connecting member 60 moves along the axial direction, thereby causing the guide member 70 and the lifting member 50 to also move along the axial direction.

[0058] This application provides two different guiding structures. In this embodiment, the lifting device 20a may further include a connecting member 60 and a guide member 70, wherein the axial direction of the guide member 70 is the same as the axial direction of the screw 30, and the guide member 70 may be disposed on the side of the screw 30. The guide member 70 is mainly used for guiding, and when the screw 30 rises, the guide member 70 can also play a supporting role to prevent the screw 30 from breaking. Optionally, the number of guide members 70 can be one or two. When the number of guide members 70 is two, the two guide members 70 are disposed on opposite sides of the screw 30, which can further improve the guiding and supporting functions.

[0059] Please refer to this as well. Figures 10-12 , Figure 10 This is a three-dimensional structural diagram of the lifting device at its highest position in another embodiment of this application. Figure 11 for Figure 10 A schematic cross-sectional view of the lifting device is shown. Figure 12 for Figure 10 The diagram shows a cross-sectional view of another embodiment of the lifting device. Specifically, when there are two guide members 70, the two guide members 70 and one screw 30 can form a triangular distribution to improve the stability of the lifting device 20a. When there are three guide members 70, the three guide members 70 themselves can form a triangular distribution, and one screw 30 can be disposed inside the triangle formed by the three guide members 70, thereby further improving the stability of the lifting device 20a.

[0060] Both the guide member 70 and the screw 30 are movably connected to the connecting member 60. That is, the screw 30 and the guide member 70 are not fixedly connected to the connecting member 60. The screw 30 can rotate relative to the connecting member 60, but it is confined to the connecting member 60 along its axial direction. Similarly, the guide member 70 is also confined to the connecting member 60 along its axial direction. Furthermore, the guide member 70 can also be connected to the lifting member 50 of the connecting member 60, thus confining the guide member 70 to the lifting member 50 along its axial direction.

[0061] Therefore, when the screw 30 rises, it can drive the connecting piece 60 to rise synchronously, and the connecting piece 60 can drive the guide piece 70 to rise synchronously. The guide piece 70 and the connecting piece 60 together drive the lifting piece 50 to rise. When the screw 30 falls, it can drive the connecting piece 60 to fall, causing the guide piece 70 and the lifting piece 50 to move downward as well.

[0062] Optionally, please refer to the following as well. Figures 13-16 , Figure 13 This is a three-dimensional structural diagram of the screw, guide member, and connector in one embodiment of this application. Figure 14 for Figure 13 The exploded view of the screw, guide, and connector shown. Figure 15 This is a three-dimensional structural diagram from another perspective of the screw, guide member, and connector member in one embodiment of this application. Figure 16 This is an exploded view of the guide member and lifting member in one embodiment of this application. The lifting device 20a also includes a second bearing 33, which is sleeved on the bottom end of the screw 30 and abuts against the external thread protruding from the side wall of the screw 30. The connecting member 60 has a second receiving groove 61 on its upper surface near the air outlet device 10a, and the second bearing 33 is disposed in the second receiving groove 61 and abuts against the bottom wall of the second receiving groove 61. The other end of the screw 30 passes through the connecting member 60, and the through part is engaged with the lower surface of the connecting member 60 by a second E-type buckle 34. When the screw 30 rises, the connecting member 60 is driven to rise by the second E-type buckle 34, and when the screw 30 falls, the connecting member 60 is driven to fall by the second bearing 33.

[0063] Optionally, the connecting member 60 has a third receiving groove 62 on its upper surface near the air outlet device 10a, and the lifting member 50 has a fourth receiving groove 52 on its lower surface away from the air outlet device 10a. The lower end of the guide member 70 is located in the third receiving groove 62 and abuts against the bottom wall of the third receiving groove 62, while the upper end of the guide member 70 is located in the fourth receiving groove 52 and abuts against the top wall of the fourth receiving groove 52. When the screw 30 drives the connecting member 60 to rise, the connecting member 60 can drive the guide member 70 to rise through the bottom wall of the third receiving groove 62, and the guide member 70 and the screw 30 together drive the lifting member 50 to rise. When the screw 30 drives the connecting member 60 to fall, the screw 30 can drive the lifting member 50 to fall, and the lifting member 50 can drive the guide member 70 to fall through the top wall of the fourth receiving groove 52, thereby causing the guide member 70 and the connecting member 60 to fall synchronously.

[0064] Please refer to this as well. Figures 17-18 , Figure 17 This is a three-dimensional structural diagram of the lifting device and the base in one embodiment of this application. Figure 18This is an exploded view of the protective shell and connecting member according to one embodiment of this application. In this embodiment, the fan 1 further includes a base 30a, which includes a chassis 80 and a protective shell 81. The protective shell 81 is fixed to the chassis 80, and the mating member 40 is fixed to the end of the protective shell 81 opposite to the chassis 80. The connecting member 60, a portion of the screw 30, and a portion of the guide member 70 are disposed inside the protective shell 81. The connecting member 60 has a first guide portion 63 on its periphery, and the protective shell 81 has a second guide portion 82 on its inner wall. The first guide portion 63 and the second guide portion 82 cooperate with each other to allow the connecting member 60 to slide on the protective shell 81.

[0065] In addition to the air outlet device 10a and the lifting device 20a, the fan 1 may also include a base 30a. The base 30a is mainly used to place the fan 1 on the ground, table, or other support surfaces. The base 30a may include a chassis 80 and a protective shell 81. The chassis 80 is mainly used to support the fan on the support surface, and therefore the chassis 80 is the lowest component of the fan 1.

[0066] The protective shell 81 can be fixed to the chassis 80. The protective shell 81 is mainly used to protect various components in the lifting device 20a, such as the connecting part 60, the screw 30, and the guide part 70, which are located inside the protective shell 81. In this embodiment, the mating part 40 can be fixed to the upper end of the protective shell 81 away from the chassis 80. For example, the mating part 40 can be fixed to the protective shell 81 by a snap-fit. Since the base 30a is set on the surface to be supported and is in a fixed state, the protective shell 81 is also fixed, and the mating part 40 fixed to the protective shell 81 is also in a fixed state. Therefore, the mating part 40 can always remain fixed, thereby engaging with the screw 30 threadedly to make the screw 30 move up and down.

[0067] In addition, in this embodiment, a first guide portion 63 can be provided on the periphery of the connector 60, and a second guide portion 82 can be provided on the inner wall of the protective shell 81. The first guide portion 63 includes one of a slider and a slide groove, and the second guide portion 82 includes the other of a slider and a slide groove. The slider is disposed in the slide groove so that the connector 60 is slidably connected to the protective shell 81, which can provide guidance for the up and down movement of the connector 60.

[0068] Optionally, there may be multiple first guide portions 63 and multiple second guide portions 82. Each of the multiple first guide portions 63 may be either a slider or a slide groove, and each of the multiple second guide portions 82 may be either a slider or a slide groove. Alternatively, a portion of the multiple first guide portions 63 may be either a slider or a slide groove, while the remaining portion may be either a slider or a slide groove; a portion of the multiple second guide portions 82 may be either a slider or a slide groove, while the remaining portion may be either a slider or a slide groove.

[0069] Please refer to this again. Figure 4 , Figure 5 ,as well as Figure 9 In this embodiment, the fan 1 further includes a spiral cable 90, which is disposed on one side of the screw 30 and spirally arranged along the axial direction of the screw 30. One end of the spiral cable 90 is used to electrically connect to an external power source, and the other end is used to electrically connect to the motor module 20.

[0070] The fan 1 may also include a cable, which connects an external power source to the motor module 20, thereby supplying power to the motor module 20. The cable may also connect to the motor in the exhaust module 11, or even the motor in the oscillation module 12. In this embodiment, the cable can be a spiral cable 90, which is a cable arranged in a spiral pattern, such as the cable of a landline telephone. Compared to a regular straight cable, the spiral cable 90 can remain taut and will not change position arbitrarily. The spiral cable 90 also reduces the risk of interference between the cable and the screw 30, preventing the screw 30 from rubbing against or scratching the cable, or even the cable winding onto the screw 30.

[0071] In this embodiment, the air outlet device 10a has a lowest position and a highest position. When the air outlet device 10a is in the lowest position, the spiral cable 90 is in a stretched state.

[0072] The air outlet device 10a, driven by the lifting device 20a, has a lowest position (descending to the lowest point) and a highest position (rising to the highest point). Similarly, the motor module 20, screw 30, and lifting component 50 in the lifting device 20a rise and fall together with the air outlet device 10a, and also have a lowest and highest position. When the air outlet device 10a is in the lowest position, that is, when the motor module 20 connected to the spiral cable 90 is also in the lowest position, the spiral cable 90 is in a stretched state. This further prevents the spiral cable 90 from swaying and further prevents interference between the spiral cable 90 and the screw 30.

[0073] In this embodiment, when the lifting device 20a further includes a connector 60 and a guide 70 in the same axial direction as the screw 30, the guide 70 is disposed on one side of the screw 30, the screw 30 and the guide 70 are both connected to the connector 60 and are limited to the connector 60 along the axial direction of the screw 30, and the guide 70 is also connected to the lifting member 50 and is limited to the lifting member 50 along the axial direction of the guide 70; a portion of the spiral cable 90 is disposed within one of the guides 70.

[0074] Based on the configuration of the spiral cable 90 and the guide member 70, this embodiment can further optimize the internal space of the protective housing 81 by placing a portion of the spiral cable 90 within the guide member 70. The guide member 70 restricts contact between the spiral cable 90 and the screw 30.

[0075] Of course, in other implementations, the cable can also be a conventional straight cable.

[0076] Please refer to this as well. Figures 19-20 , Figure 19 This is a three-dimensional structural diagram of the lifting device in another embodiment of this application. Figure 20 for Figure 19 The exploded view of the lifting device is shown. In this embodiment, the lifting device 20a further includes a guide shell 71, which is connected to one side of the lifting member 50 along its circumference. The screw 30 and the mating member 40 are disposed within the guide shell 71. The fan 1 further includes a base 30a, which includes a chassis 80 and a protective shell 81. The protective shell 81 is fixed to the chassis 80, the guide shell 71 is disposed within the protective shell 81, and the mating member 40 is disposed within the protective shell 81 and fixed to the chassis 80. When the screw 30 moves along its axial direction, the lifting member 50 moves along the axial direction, and the guide shell 71 moves relative to the protective shell 81 along the axial direction.

[0077] In another guiding scheme, a guide shell 71 can be provided, which is disposed circumferentially around the lifting member 50 and on its lower side. In other words, the periphery of the lifting member 50 can extend downward to form a ring of guide shell 71. This guide shell 71 can be disposed inside the protective shell 81. The chassis 80 and the protective shell 81 are the same as in the above embodiments, and will not be described again in this embodiment.

[0078] When the screw 30 drives the lifting component 50 to rise, the lifting component 50 simultaneously drives the guide shell 71 to rise. At this time, the guide shell 71 will partially protrude from the protective shell 81. The guide shell 71 still serves as a guide. Furthermore, after the screw 30 and the guide shell 71 rise, the guide shell 71 not only covers the interior of the protective shell 81, but also simultaneously covers the interior of the guide shell 71. From the outside, the user can only see the protective shell 81 and the guide shell 71, and cannot see the protruding screw 30. This prevents external dust, impurities, etc. from entering the interior of the guide shell 71 and the protective shell 81, thereby affecting the performance of the lifting device 20a.

[0079] In addition, in this embodiment, the mating part 40 can be disposed inside the protective shell 81 and fixed on the chassis 80. At this time, the mating part 40 is rod-shaped and has internal threads for threaded connection of the screw 30.

[0080] Please refer to Figure 21 , Figure 21 This is an exploded view of the guide shell and the protective shell according to one embodiment of this application. In this embodiment, the outer wall of the guide shell 71 is provided with a third guide portion 72, and the inner wall of the protective shell 81 is provided with a fourth guide portion 83. The third guide portion 72 and the fourth guide portion 83 cooperate with each other to make the guide shell 71 slidably connected to the protective shell 81.

[0081] In this embodiment, a third guide portion 72 is provided on the outer wall of the guide shell 71, and a fourth guide portion 83 is provided on the inner wall of the protective shell 81. The third guide portion 72 includes one of a slider and a slide groove, and the fourth guide portion 83 includes the other of a slider and a slide groove. The slider is disposed in the slide groove so that the guide shell 71 is slidably connected to the protective shell 81, which can provide guidance for the up and down movement of the guide shell 71.

[0082] Optionally, there may be multiple third guide portions 72 and multiple fourth guide portions 83. Each of the multiple third guide portions 72 may be either a slider or a slide groove, and each of the multiple fourth guide portions 83 may be either a slider or a slide groove. Alternatively, a portion of the multiple third guide portions 72 may be either a slider or a slide groove, while the remaining portion may be either a slider or a slide groove; a portion of the multiple fourth guide portions 83 may be either a slider or a slide groove, while the remaining portion may be either a slider or a slide groove.

[0083] Please refer to Figure 22 , Figure 22 This is a three-dimensional structural diagram of the spiral cable and guide shell in one embodiment of this application. In this embodiment, the fan 1 further includes a spiral cable 90, a portion of which is disposed on the inner wall of the guide shell 71 and spirally arranged along the axial direction of the guide shell 71. One end of the spiral cable 90 is used for electrical connection to an external power source, and the other end is used for electrical connection to the motor module 20.

[0084] A spiral cable 90 can also be added to the guide housing 71. The spiral cable 90 connects the external power supply to the motor module 20, thereby supplying power to the motor module 20. The spiral cable 90 can also connect to the motor in the air outlet module 11, or even the motor in the oscillating module 12. The spiral cable 90 is a cable arranged in a spiral, such as the cable of a landline telephone. Compared with ordinary straight cables, the spiral cable 90 can be kept in a taut state and will not change position arbitrarily. Compared with ordinary straight cables, the spiral cable 90 can reduce the risk of interference between the cable and the screw 30, and prevent the screw 30 from rubbing against or scratching the cable, or even the cable from winding onto the screw 30.

[0085] In this embodiment, a portion of the spiral cable 90 can be disposed on the inner wall of the guide shell 71 and spirally arranged along the axial direction of the guide shell 71, which can make the spiral cable 90 away from the screw 30, further reducing the risk of interference between the spiral cable 90 and the screw 30.

[0086] Please refer to this as well. Figures 4-5 ,as well as Figure 23 , Figure 23 for Figure 4 The image shows a front view of the lifting device after removing the lifting component. In this embodiment, the motor module 20 includes a motor 21, a first gear 22, and a second gear 23. The output shaft of the motor 21 is connected to the first gear 22, and the first gear 22 is rotatably connected to the second gear 23. The second gear 23 is sleeved on the screw 30 and is limited to the screw 30 in both the axial and circumferential directions. The motor 21 is fixed to the lifting component 50.

[0087] When the motor 21 is working, it sequentially drives the first gear 22 to rotate, the second gear 23 to rotate, and the screw 30 to rotate. The screw 30 drives the lifting member 50 and the first gear 22 to move along the axial direction, and the lifting member 50 drives the motor 21 and the second gear 23 to move along the axial direction.

[0088] Regardless of the specific structure described above, the motor module 20 can include a motor 21, a first gear 22, and a second gear 23. The output shaft of the motor 21 is connected to the first gear 22, and the first gear 22 is rotatably connected to the second gear 23. The second gear 23 is fitted onto the screw 30, and is confined within the screw 30 in both the axial and circumferential directions. Specifically, the second gear 23 can engage with the screw 30 via a shaped shaft, allowing the second gear 23 to rotate synchronously with the screw 30 in the circumferential direction. The lower part of the second gear 23 abuts against the external thread of the screw 30, and the upper part abuts against the first bearing 31.

[0089] Furthermore, the motor 21 can be fixed to the lifting component 50. When the motor 21 operates, it drives the first gear 22 to rotate, which in turn drives the second gear 23 to rotate. The second gear 23 then drives the screw 30 to rotate. The screw 30 engages with the mating component 40, causing it to move up and down. Simultaneously, the screw 30 drives the second gear 23 and the lifting component 50 to move up and down as well. Since the motor 21 is fixed to the lifting component 50, and the first gear 22 is connected to the motor 21, the motor 21 and the first gear 22 move up and down synchronously, ensuring that the first gear 22 and the second gear 23 remain connected at all times.

[0090] Please refer to this as well. Figure 10 , Figures 24-27 , Figure 24 for Figure 10 The diagram shows the three-dimensional structure of the lifting device at its lowest position. Figure 25 for Figure 24 A schematic cross-sectional view of the lifting device is shown. Figure 26 for Figure 10 A schematic cross-sectional view of the lifting device is shown. Figure 27 for Figure 10 The exploded view of the lifting device is shown. In this embodiment, the motor module 20 includes a motor 21, a worm gear 24, and a worm wheel 25. The worm gear 24 is connected to the output shaft of the motor 21, and the worm wheel 25 is connected to the worm gear 24. The worm wheel 25 is sleeved on the screw 30 and is limited to the screw 30 in the axial and circumferential directions. The motor 21 is fixed to the lifting component 50.

[0091] This embodiment provides another structure for the motor module 20. In this embodiment, a worm gear 25 and a worm 24 can be used to transmit the force output by the motor 21 to the screw 30. In this case, the motor 21 can be set horizontally without the need for vertical setting, thereby changing the setting position of the motor. Furthermore, the worm gear 25 and the worm 24 can cooperate to achieve a self-locking function.

[0092] In this embodiment, the lifting component 50 includes a lifting platform 53, a lifting motor bracket 54, and a lifting motor bracket cover 55. The lifting platform 53 is used to connect the oscillating device 56. The lifting motor bracket 54 is fixed below the lifting platform 53. The motor 21 is disposed on the lifting motor bracket 54. The lifting motor bracket cover 55 is used to enclose at least a portion of the motor 21, so as to cooperate in covering the motor 21 with the lifting motor bracket cover 55.

[0093] In this embodiment, the oscillating device 56 includes a rotary table 57, an oscillating motor 58, and an oscillating gear 59. The rotary table 57 is mounted on the lifting platform 53 and can rotate relative to the lifting platform 53. The air outlet device is mounted on the rotary table 57. A gear is fixed on the lifting platform 53. The oscillating motor 58 is mounted on the rotary table 57 and connected to the oscillating gear 59. The oscillating gear 59 is connected to the gear on the rotary table 57. When the oscillating motor 58 is working, it can drive the oscillating gear 59 to rotate. Since the lifting platform 53 is fixed in the circumferential direction, the oscillating gear 59 will drive the rotary table 57 to rotate relative to the lifting platform 53, thereby driving the air outlet device to rotate. In addition, the power supply board 41 of the fan can also be mounted on the rotary table 57.

[0094] In this embodiment, a cable holder 41 can also be provided below the rotary table 57 for securing cables and adjusting their position.

[0095] In this embodiment, a micro switch 43 can also be provided on the lifting motor bracket 54. When the lifting motor bracket 54 in the lifting component 50 descends to the preset position, the micro switch 43 will abut against the mating component 40, thereby stopping the motor 21 from working.

[0096] In this embodiment, the protective shell 81 can be connected to the chassis 80 by locking nut 84, and a counterweight 85 can also be provided on the chassis 80 to increase the weight of the chassis 80.

[0097] It is worth noting that, in Figure 10 , Figures 24-27 In the technical solutions mentioned above, the specific structures of the lifting component 50, the oscillating device 56, the cable holder 42, and the micro switch 43 are not only applicable to the motor module 20 composed of the worm gear 25 and the worm 24, but also to the aforementioned components. Figures 1-23 The various technical solutions shown are also applicable and should not be considered as applicable only to the motor module 20 composed of worm gear 25 and worm 24.
