Description

Technical Field

[0001] This application relates to the field of fan technology, specifically to a lifting device and a fan. Background Technology

[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 is adjusted using a screw-on knob, which is time-consuming and laborious. Utility Model Content

[0003] In view of this, this application provides a lifting device and a fan, wherein the lifting device is easy to adjust the height and saves time and effort.

[0004] This application provides a lifting device having a minimum adjustment state and a maximum adjustment state. The lifting device includes a base module, a lifting member, a first elastic member, and a driving member. The lifting member is movable in a direction approaching or away from the base module. The lifting member has multiple first mating parts arranged along the moving direction and is used to connect to a functional device. One end of the first elastic member is connected to the base module, and the other end of the first elastic member is connected to the lifting member. When the lifting device is in the minimum adjustment state, the first elastic member is in a deformed state. The driving member includes a driving part and a second mating part connected to the driving part. The driving part can drive the second mating part to separate from the first mating part. During the lifting device's ascent, the driving part drives the second mating part to separate from the first mating part. The first elastic member in the deformed state can cause the lifting member to move in a direction away from the base module, so that the lifting device is in the maximum adjustment state. When the lifting device is in the maximum adjustment state, or during the lifting device's descent, the second mating part can also move towards the first mating part, so that the second mating part connects with the first mating part.

[0005] Furthermore, the driving member satisfies at least one of the following conditions: the driving part of the driving member is rotatably connected to the base module to drive the second mating part to separate from the first mating part, or to move the second mating part toward the first mating part; the driving part of the driving member is movably connected to the base module to drive the second mating part to separate from the first mating part, or to move the second mating part toward the first mating part.

[0006] Furthermore, the first mating part is a slot, and the second mating part is a holding part; wherein, during the upward movement of the lifting device, the holding part is driven to separate from the slot by the driving part, and the first elastic member in the deformed state can cause the lifting member to move in a direction away from the base module, so that the lifting device is in the highest adjustment state; when the lifting device is in the highest adjustment state, or during the downward movement of the lifting device, the holding part can also move towards the slot, so that the holding part is connected to the slot.

[0007] Furthermore, the retaining part has a first retaining surface and a second retaining surface that are bent and connected to the card slot and are facing the card slot. The first retaining surface and the second retaining surface are respectively inclined relative to the inner wall of the card slot.

[0008] Furthermore, the card slot has a first inclined surface and a second inclined surface arranged opposite to each other along the moving direction. The first inclined surface and the second inclined surface are respectively inclined relative to the inner sidewall of the card slot to guide the holding part into the card slot.

[0009] Furthermore, the first mating part is a first magnetic attraction part, and the second mating part is a second magnetic attraction part; wherein, during the process of the lifting device rising, the driving part drives the second magnetic attraction part to separate from the first magnetic attraction part, and the first elastic member in the deformed state can cause the lifting member to move in a direction away from the base module, so that the lifting device is in the highest adjustment state; when the lifting device is in the highest adjustment state, or during the process of the lifting device falling, the second magnetic attraction part can also move towards the first magnetic attraction part, and the second magnetic attraction part and the first magnetic attraction part are magnetically attracted to each other, so that the second magnetic attraction part and the first magnetic attraction part are connected.

[0010] Furthermore, the base module includes a base and a sleeve assembly. The sleeve assembly is mounted on the base and includes a sleeve and a fixing member. The sleeve has a movable cavity, and the lifting member is at least partially located in the movable cavity. The lifting member can move relative to the sleeve in a direction closer to or farther from the base. The fixing member is disposed in the movable cavity, and the driving part is rotatably connected to the fixing member.

[0011] Furthermore, the fixing member includes a first fixing part, a second fixing part, and a third fixing part that are bent and connected together. The first fixing part and the third fixing part are located on opposite sides of the second fixing part. The first fixing part and the third fixing part are arranged opposite to each other, and the first fixing part, the second fixing part, and the third fixing part enclose a setting space. The driving part is at least partially located within the setting space. The lifting device also includes a rotating shaft that passes through the first fixing part, the driving part, and the third fixing part in sequence, so as to enable the driving part to be rotatably connected to the fixing member.

[0012] Furthermore, the lifting device also includes a second elastic element. The second fixing part has a first positioning post on the side facing the driving part. The driving part has a groove facing the second fixing part, the groove corresponding to the first positioning post, and a second positioning post inside the groove. One end of the second elastic element is sleeved on the outer periphery of the first positioning post, and the other end of the second elastic element is sleeved on the outer periphery of the second positioning post. When the second mating part is separated from the first mating part, the second elastic element is in a compressed state. When the driving part drives the second mating part to move closer to the first mating part, the second elastic element elastically recovers.

[0013] Further, the first elastic element satisfies at least one of the following conditions: the first elastic element is a coil spring, one end of which is connected to the end of the sleeve away from the base, and the other end of which is connected to the end of the lifting member near the base; or the first elastic element is a linear spring, one end of which is connected to the bottom of the sleeve, and the other end of which is connected to the end of the lifting member near the base.

[0014] Furthermore, when the second mating part is connected to the first mating part, there is a gap between the driving part and the base; when the driving part drives the second mating part to separate from the first mating part, the gap between the driving part and the base gradually decreases; when the second mating part separates from the first mating part, the driving part at least partially abuts against the base.

[0015] Furthermore, the lifting device also includes a buffer assembly, which includes a first buffer member and a second buffer member. The first buffer member protrudes from the inner sidewall of the sleeve. The lifting member has an opening that penetrates the inner and outer sidewalls of the lifting member. The second buffer member is connected to the lifting member and disposed in the opening. When the lifting device is in the highest adjustment state, the first buffer member abuts against the second buffer member.

[0016] This application provides a fan, which includes a lifting device and an air outlet device provided in this application. The air outlet device is installed on one side of the lifting device, and the lifting device is used to raise and lower the air outlet device.

[0017] In the lifting device provided in this application, when the second mating part is connected to the first mating part, the relative position of the lifting member and the base module is limited, so that the lifting device is in the lowest adjustment state, or in the highest adjustment state, or in a state between the lowest and highest adjustment states, to meet the user's needs for the lifting member to be at different heights. When the lifting device is applied to a fan, it can adapt to users of different heights or different application scenarios, improving the performance of the fan. Specifically, when it is necessary to change the lifting device in the lowest adjustment state, or to raise the lifting device, the driving part drives the second mating part to separate from the first mating part, so that the lifting member can move in a direction closer to or away from the base module. At this time, the first elastic member in the deformed state undergoes a restorative deformation, which can drive the lifting member to move in a direction away from the base module, so that the lifting device can be in the highest adjustment state without the user having to lift the lifting member forcefully. Furthermore, if the user wants to put the lifting device in the highest adjustment state, the second mating part can be connected to the first mating part to switch the lifting device to the highest adjustment state. If a user wants to position the lifting device in a state between the lowest and highest adjustment states, the lifting component can be lowered to a preset height, and then the second mating part can be driven to move closer to the first mating part. This allows the second mating part to engage with the first mating part, fixing the relative position of the lifting component and the base module, and ultimately switching the lifting device to a state between the highest and lowest adjustment states. The lifting device of this application facilitates height adjustment of the lifting component, allowing users to easily raise and lower the air outlet device according to their needs when using it with a fan, thus stopping the air outlet device at the desired height. The lifting device provided in this application offers a simple, time-saving, and labor-saving height adjustment method for the lifting component, and can stop the lifting component at multiple heights to meet different user height requirements, thereby improving the user experience.

[0024] 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 is adjusted using a screw-on knob, which is time-consuming and laborious.

[0025] Please see Figures 1 to 5 This application provides a lifting device 100, which has a minimum adjustment state and a maximum adjustment state. The lifting device 100 includes a base module 110, a lifting member 120, a first elastic member 130, and a driving member 140. The lifting member 120 is movable in a direction close to or away from the base module 110. The lifting member 120 has a plurality of first mating parts 121 arranged along the moving direction (as shown by the X direction in the figure). The lifting member 120 is used to connect to a functional device. One end of the first elastic member 130 is connected to the base module 110, and the other end of the first elastic member 130 is connected to the lifting member 120. When the lifting device 100 is in the minimum adjustment state, the first elastic member 130 is in a deformed state. The driving member 140 includes a driving part 141. The second mating part 142 is connected to the drive part 141, and the drive part 141 can drive the second mating part 142 to separate from the first mating part 121. During the lifting device 100's ascent, the drive part 141 drives the second mating part 142 to separate from the first mating part 121, and the first elastic member 130, which is in a deformed state, can cause the lifting member 120 to move away from the base module 110, so that the lifting device 100 is in the highest adjustment state. When the lifting device 100 is in the highest adjustment state, or during the lifting device 100's descent, the second mating part 142 can also move towards the first mating part 121, so that the second mating part 142 is connected to the first mating part 121.

[0026] Understandably, when the lifting device 100 is in the lowest adjustment state, the lifting member 120 is in the lowest position relative to the base module 110; when the lifting device 100 is in the highest adjustment state, the lifting member 120 is in the highest position relative to the base module 110.

[0027] Optionally, the functional device may be, but is not limited to, an air outlet device 210, a display screen, a light, etc. In this embodiment, taking the lifting device 100 applied to the fan 200 as an example to adjust the height of the air outlet device 210 of the fan 200, it should not be construed as a limitation on the application scenario of the functional device.

[0028] In the terminology of this application, "multiple" means two or more, and can be, but is not limited to, two, three, four, six, eight, ten, twelve, fifteen or eighteen, etc.

[0029] Understandably, when the lifting device 100 switches from the lowest adjustment state to the highest adjustment state, the lifting member 120 moves away from the base module 110; when the lifting device 100 switches from the highest adjustment state to the lowest adjustment state, the lifting member 120 moves closer to the base module 110.

[0030] Understandably, when the lifting device 100 is in the lowest adjustment state, the first elastic element 130 is in a deformed state. Specifically, when the lifting device 100 is in the lowest adjustment state, the first elastic element 130 is in a compressed or wound state. When the lifting device 100 changes from the lowest adjustment state to the highest adjustment state, the first elastic element 130 will elastically recover, thereby driving the lifting member 120 to move away from the base module 110.

[0031] Understandably, the second mating part 142 can be connected to any one of the plurality of first mating parts 121 so that the lifting device 100 can be in the lowest adjustment state, or the highest adjustment state, or a state between the lowest adjustment state and the highest adjustment state, so as to meet the user's needs for the lifting component 120 to be at different heights.

[0032] Understandably, when the lifting device 100 is in the lowest adjustment state, the second mating part 142 connects to the one of the plurality of first mating parts 121 closest to the base module 110; when the lifting device 100 is in the highest adjustment state, the second mating part 142 connects to the one of the plurality of first mating parts 121 furthest from the base module 110; when the lifting state is in a state between the lowest and highest adjustment states, the second mating part 142 connects to one of the plurality of first mating parts 121 except for the first and last two.

[0033] Understandably, if the driving part 141 can drive the second mating part 142 to separate from the first mating part 121, then the driving part 141 can drive the second mating part 142 to rotate or move in a direction away from the first mating part 121, so that the second mating part 142 disengages from the first mating part 121, the second mating part 142 separates from the first mating part 121, and the lifting member 120 can move relative to the base module 110.

[0034] Understandably, in the terminology of this application, the process of the lifting device 100 rising refers to the process of the lifting member 120 moving away from the base module 110, and the process of the lifting device 100 falling refers to the process of the lifting member 120 moving towards the base module 110.

[0035] Understandably, the second mating part 142 can be connected to the first mating part 121 in a manner that is, but not limited to, snap-fit ​​connection, magnetic connection, plug-in connection, etc.

[0036] In the lifting device 100 provided in this embodiment, when the second mating part 142 is connected to the first mating part 121, the relative position of the lifting member 120 and the base module 110 is limited, so that the lifting device 100 is in the lowest adjustment state, or in the highest adjustment state, or in a state between the lowest and highest adjustment states, to meet the user's needs for the lifting member 120 to be at different heights. When the lifting device 100 is applied to the fan 200, it can adapt to users of different heights or different application scenarios, improving the performance of the fan 200. Specifically, when it is necessary to change the lifting device 100 in the lowest adjustment state, or to make the lifting device 100 rise, the second mating part 142 is driven to separate from the first mating part 121 by the driving part 141, so that the lifting member 120 can move in a direction closer to or away from the base module 110. At this time, the first elastic element 130, which is in a deformed state, returns to its original deformed state, which can drive the lifting element 120 to move away from the base module 110. The lifting device 100 can be in its highest adjustment state without the user having to lift the lifting element 120 forcefully. Furthermore, if the user wants to place the lifting device 100 in its highest adjustment state, the second mating part 142 can be connected to the first mating part 121 to switch the lifting device 100 to the highest adjustment state. If the user wants to place the lifting device 100 in a state between the lowest and highest adjustment states, the lifting element 120 can be pressed down to a preset height, and then the second mating part 142 can be driven to move towards the first mating part 121, so that the second mating part 142 engages with the first mating part 121, thereby fixing the relative position of the lifting element 120 and the base module 110, and ultimately switching the lifting device 100 to a state between the highest and lowest adjustment states. The lifting device 100 of this embodiment facilitates the adjustment of the height of the lifting component 120. When the lifting device 100 is applied to the fan 200, the user can easily raise or lower the air outlet device 210 according to their needs, positioning it at the desired height. The lifting device 100 provided in this embodiment offers a simple, time-saving, and labor-saving method for adjusting the height of the lifting component 120. Furthermore, it can position the lifting component 120 at multiple heights to meet different user requirements, thereby enhancing the user experience.

[0037] Understandably, the drive member 140 has a locked state and an unlocked state relative to the lifting member 120. When the drive member 140 is in the locked state relative to the lifting member 120, the second mating part 142 connects to one of the plurality of first mating parts 121 to limit the relative position of the lifting member 120 and the sleeve 113. When the drive member 140 is in the unlocked state relative to the lifting member 120, the second mating part 142 separates from the first mating part 121 to adjust the relative position of the drive member 140 and the lifting member 120.

[0038] Please see Figure 6 and Figure 7 Optionally, the lifting member 120 has a receiving cavity 123, the plurality of first mating parts 121 are located in the receiving cavity 123, and the driving member 140 is at least partially located in the receiving cavity 123.

[0039] In this embodiment, when the lifting device 100 is in its highest adjustment state, the second mating portion 142 of the drive member 140 connects to the one of the plurality of first mating portions 121 closest to the base module 110, and the second mating portion 142 of the drive member 140 is located within the receiving cavity 123. During the descent of the lifting device 100, the lifting member 120 moves toward the base module 110, and the second mating portion 142 of the drive member 140 and the drive portion 141 of the drive member 140 are at least partially located within the receiving cavity 123.

[0040] Please see Figure 8 In some embodiments, the drive member 140 satisfies at least one of the following conditions: the drive portion 141 of the drive member 140 is rotatably connected to the base module 110 to drive the second mating portion 142 to separate from the first mating portion 121, or to move the second mating portion 142 toward the first mating portion 121; the drive portion 141 of the drive member 140 is movably connected to the base module 110 to drive the second mating portion 142 to separate from the first mating portion 121, or to move the second mating portion 142 toward the first mating portion 121.

[0041] Understandably, in some embodiments, the drive member 140 satisfies that the drive part 141 is rotatably connected to the base module 110; in other embodiments, the drive member 140 satisfies that the drive part 141 is movably connected to the base module 110; and in still other embodiments, the drive member 140 satisfies both the requirement of being rotatably connected to the base module 110 and the requirement of being movably connected to the base module 110.

[0042] In one embodiment of this application, when the driving part 141 of the driving member 140 is rotatably connected to the base module 110, by applying a preset pressure such as foot pedal or hand pressure to the driving part 141, the driving part 141 can rotate relative to the base module 110, further driving the second mating part 142 to move away from the first mating part 121, so as to drive the second mating part 142 to separate from the first mating part 121, thereby enabling the lifting member 120 to move relative to the lifting module, thereby facilitating the adjustment of the relative position of the lifting member 120 and the base module 110. In another embodiment of this application, when the driving part 141 of the driving member 140 is movably connected to the base module 110, by applying a preset force to the driving part 141, such as pushing with a foot or pulling with a hand, the driving part 141 can move relative to the base module 110 in a direction away from the first mating part 121, further driving the second mating part 142 to move away from the first mating part 121, thereby driving the second mating part 142 to separate from the first mating part 121, and thus enabling the lifting member 120 to move relative to the lifting module, thereby facilitating the adjustment of the relative position of the lifting member 120 and the base module 110. The method by which the driving part 141 drives the second mating part 142 away from the first mating part 121 is simple, time-saving, and labor-saving, making it convenient for the user to further adjust the relative position of the lifting member 120 and the base module 110.

[0043] In some embodiments, the base module 110 includes a base 111 and a sleeve assembly 112. The sleeve assembly 112 is mounted on the base 111. The sleeve assembly 112 includes a sleeve 113 and a fixing member 114. The sleeve 113 has a movable cavity 1131. The lifting member 120 is at least partially located in the movable cavity 1131. The lifting member 120 can move relative to the sleeve 113 in a direction close to or away from the base 111. The fixing member 114 is disposed in the movable cavity 1131. The driving part 141 is rotatably connected to the fixing member 114.

[0044] Understandably, the drive element 140 is partially located inside the moving cavity 1131 and partially located outside the moving cavity 1131.

[0045] Understandably, the fixing member 114 is connected to the bottom wall of the movable cavity 1131.

[0046] In this embodiment, the base 111 provides support for the sleeve assembly 112 and the lifting member 120. The sleeve 113 of the sleeve assembly 112 has a movable cavity 1131, which protects the components such as the lifting member 120, the driving member 140, and the fixing member 114 located in the movable cavity 1131. This provides dust protection and prevents accidental contact and injury to the user when the lifting member 120 moves relative to the sleeve 113. On the other hand, the sleeve 113 is fitted around the outer periphery of the lifting member 120 near the base 111. The sleeve 113 guides the movement direction of the lifting member 120, allowing it to move along the extension direction of the sleeve 113 towards or away from the base 111, thus improving the accuracy of height adjustment of the lifting member 120. The fixing member 114 is disposed in the moving cavity 1131, and the driving part 141 is rotatably connected to the fixing member 114 to drive the second mating part 142 to move toward or away from the first mating part 121, so as to realize the switching of the state of the lifting device 100.

[0047] Please see also Figure 9 In some embodiments, the fixing member 114 includes a first fixing part 1141, a second fixing part 1142, and a third fixing part 1143 that are bent and connected together. The first fixing part 1141 and the third fixing part 1143 are located on opposite sides of the second fixing part 1142. The first fixing part 1141 and the third fixing part 1143 are arranged opposite to each other. The first fixing part 1141, the second fixing part 1142, and the third fixing part 1143 enclose a setting space 1144. The driving part 141 is at least partially located within the setting space 1144. The lifting device 100 also includes a rotating shaft that passes through the first fixing part 1141, the driving part 141, and the third fixing part 1143 in sequence, so that the driving part 141 can be rotatably connected to the fixing member 114.

[0048] Understandably, the first fixing part 1141, the second fixing part 1142 and the third fixing part 1143 have a "C" shaped structure.

[0049] In this embodiment, the rotating shaft passes sequentially through the first fixing part 1141, the driving part 141, and the third fixing part 1143, so that the driving part 141 is rotatably connected to the fixing member 114. When a preset pressure is applied to the end of the driving part 141 away from the second mating part 142, the driving part 141 can be driven to rotate relative to the fixing member 114, thereby driving the second mating part 142 to separate from the first mating part 121. When the preset pressure is stopped applied to the end of the driving part 141 away from the second mating part 142, the second mating part 142 can move towards the first mating part 121, so that the second mating part 142 is engaged in the first mating part 121. The lifting device 100 provided in this embodiment has a simple and efficient state adjustment method, which saves time and effort and improves the user experience.

[0050] Please see also Figure 10 In some embodiments, the lifting device 100 further includes a second elastic member 160. The second fixing part 1142 has a first positioning post 1145 on the side facing the driving part 141. The driving part 141 has a groove 1411 facing the second fixing part 1142. The groove 1411 is provided corresponding to the first positioning post 1145. A second positioning post 1412 is provided in the groove 1411. One end of the second elastic member 160 is sleeved on the outer periphery of the first positioning post 1145, and the other end of the second elastic member 160 is sleeved on the outer periphery of the second positioning post 1412. When the second mating part 142 is separated from the first mating part 121, the second elastic member 160 is in a compressed state. When the driving part 141 drives the second mating part 142 to move closer to the first mating part 121, the second elastic member 160 elastically recovers.

[0051] Understandably, the second elastic element 160 is at least partially located within the groove 1411.

[0052] In this embodiment, the opposite ends of the second elastic member 160 are respectively sleeved on the outer periphery of the first positioning post 1145 and the outer periphery of the second positioning post 1412 to realize the movable connection between the driving member 140 and the fixing member 114. When the second mating part 142 separates from the first mating part 121, that is, when the user drives the driving part 141 to rotate in a direction away from the first mating part 121, the second elastic member 160 is in a compressed state, that is, the opposite ends of the second elastic member 160 abut against the bottom of the groove 1411 and the second fixing part 1142 respectively. When the driving part 141 drives the second mating part 142 to move closer to the first mating part 121, the second elastic member 160 elastically recovers and generates a rebound force to drive the driving part 141 to rotate relative to the fixing member 114 in a direction closer to the first mating part 121. The second elastic element 160 can assist the driving element 140 in driving the second mating part 142 to move closer to the first mating part 121, without requiring the user to forcefully reset, saving time and effort and improving the user experience.

[0053] In some embodiments, the first elastic member 130 satisfies at least one of the following conditions: the first elastic member 130 is a coil spring, one end of which is connected to the end of the sleeve 113 away from the base 111, and the other end of which is connected to the end of the lifting member 120 near the base 111; or the first elastic member 130 is a linear spring, one end of which is connected to the bottom of the sleeve 113, and the other end of which is connected to the end of the lifting member 120 near the base 111.

[0054] Understandably, in some embodiments, the first elastic element 130 is a coil spring; in other embodiments, the first elastic element 130 is a linear spring; in still other embodiments, the number of the first elastic elements 130 is multiple, and at least two of the following are true: some of the first elastic elements 130 are coil springs, and some of the first elastic elements 130 are linear springs, with the coil springs and linear springs cooperating with each other so that the first elastic element 130 can enable the lifting member 120 to move in a direction away from the base module 110.

[0055] In this embodiment, when the first elastic element 130 is a coiled spring, the opposite ends of the coiled spring are respectively connected to the end of the sleeve 113 away from the base 111 and the end of the lifting element 120 near the base 111. When the lifting device 100 is in the lowest adjustment state, the lifting element 120 has the lowest position closest to the base 111. At this time, the distance between the opposite ends of the coiled spring is the shortest, and the coiled spring is in a deformed state, specifically, in a coiled state. During the upward movement of the lifting device 100, the coiled spring undergoes elastic deformation and generates a rebound force, causing the lifting element 120 to move away from the base 111. The coiled spring gradually changes from a coiled state to a straight state. The first elastic element 130 can drive the lifting element 120 to move in the direction away from the base 111, eliminating the need for manual lifting by the user, saving time and effort, and facilitating user adjustment of the height of the lifting element 120.

[0056] In other embodiments, when the first elastic element 130 is a linear spring, the opposite ends of the linear spring are respectively connected to the bottom of the sleeve 113 and the end of the lifting element 120 near the base 111. When the lifting device 100 is in the lowest adjustment state, the lifting element 120 has the lowest position closest to the base 111, at which time the distance between the opposite ends of the linear spring is the shortest, and the linear spring is in a compressed state. During the upward movement of the lifting device 100, the linear spring undergoes elastic deformation and generates a rebound force, causing the lifting element 120 to move away from the base 111, and the linear spring gradually returns to its original length. The first elastic element 130 can drive the lifting element 120 to move in a direction away from the base 111, eliminating the need for manual lifting by the user, saving time and effort, and facilitating user adjustment of the height of the lifting element 120.

[0057] In some embodiments, when the second mating part 142 is connected to the first mating part 121, the driving part 141 has a gap with the base 111; when the driving part 141 drives the second mating part 142 to separate from the first mating part 121, the gap between the driving part 141 and the base 111 gradually decreases; when the second mating part 142 separates from the first mating part 121, the driving part 141 at least partially abuts against the base 111.

[0058] In this embodiment, when the second mating part 142 is connected to the first mating part 121, the driving member 140 is locked relative to the lifting member 120 to limit the relative position of the lifting member 120 and the base module 110. At this time, there is a gap between the driving member 141 and the base 111, which provides the driving member 141 with room to move. This allows the driving member 141 to rotate toward the base 111 when it is necessary for the driving member 141 to drive the second mating part 142 to separate from the first mating part 121, thereby gradually reducing the gap between the driving member 141 and the base 111. When the second mating part 142 separates from the first mating part 121, the driving member 141 at least partially abuts against the base 111, and the base 111 restricts the angle of movement of the driving member 141. When the user applies a preset pressure to the drive unit 141, so that the gap between the drive unit 141 and the base 111 gradually decreases until it abuts against the base 111, it means that the second mating part 142 is separated from the first mating part 121. This allows the user to perceive the relative position of the second mating part 142 and the first mating part 121, thereby adjusting the relative position of the lifting member 120 and the base 111.

[0059] Please see also Figure 9 , Figure 11 and Figure 12 In some embodiments, the lifting device 100 further includes a buffer assembly 170, which includes a first buffer 171 and a second buffer 172. The first buffer 171 protrudes from the inner sidewall of the sleeve 113. The lifting member 120 has an opening 122 that penetrates the inner and outer sidewalls of the lifting member 120. The second buffer 172 is connected to the lifting member 120 and disposed in the opening 122. When the lifting device 100 is in the highest adjustment state, the first buffer 171 abuts against the second buffer 172.

[0060] In this embodiment, the second buffer 172 is connected to the lifting member 120 and disposed in the opening 122. When the second buffer 172 is impacted, it can vibrate and have a certain elastic deformation space within the opening 122. When the lifting device 100 is in the highest adjustment state, the first buffer 171 located on the inner sidewall of the sleeve 113 abuts against the second buffer 172, and the second buffer 172 vibrates to a certain extent within the opening 122 to absorb the energy brought by the first buffer 171 impacting the second buffer 172. This allows the lifting member 120 to quickly stop at the highest position relative to the base module 110, thereby improving the stability of the lifting device 100 when switching to the highest adjustment state and enhancing the user experience.

[0061] Optionally, the second buffer 172 includes a first sub-part 1721 and a second sub-part 1722 connected together. The first sub-part 1721 is connected to the lifting member 120 and located in the opening 122. The second sub-part 1722 protrudes from the surface of the first sub-part 1721 and is closer to the first buffer 171 than the first sub-part 1721.

[0062] Understandably, the second sub-part 1722 protrudes from the surface of the first sub-part 1721 and extends beyond the inner wall of the lifting member 120. When the lifting member 120 abuts against the sleeve 113, the second sub-part 1722 abuts against the first buffer member 171. The first sub-part 1721 and the second sub-part 1722 vibrate within the opening 122 to absorb the impact energy from the first buffer member 171, allowing the lifting member 120 to quickly reach its highest position relative to the base module 110, thereby improving the stability of the lifting device 100.

[0063] Please see also Figure 13 Optionally, in some embodiments, the first mating part 121 is a slot 1213, and the second mating part 142 is a holding part 1423; wherein, during the process of the lifting device 100 rising, the driving part 141 drives the holding part 1423 to separate from the slot 1213, and the first elastic member 130 in a deformed state can cause the lifting member 120 to move in a direction away from the base module 110, so that the lifting device 100 is in the highest adjustment state; when the lifting device 100 is in the highest adjustment state, or during the process of the lifting device 100 falling, the holding part 1423 can also move towards the slot 1213, so that the holding part 1423 is connected to the slot 1213.

[0064] Understandably, the holding part 1423 can be engaged with any one of the plurality of slots 1213 so that the lifting device 100 can be in the lowest adjustment state, or the highest adjustment state, or a state between the lowest and highest adjustment states, so as to meet the user's needs for the lifting component 120 to be at different heights.

[0065] In this embodiment, the first mating part 121 is configured as a slot 1213, and the second mating part 142 is configured as a holding part 1423. The holding part 1423 moves towards or away from the slot 1213 under the drive of the driving part 141, so that it engages with or disengages from the slot 1213. When the holding part 1423 engages with the slot 1213, the relative position of the lifting member 120 and the base module 110 is fixed, allowing the lifting device 100 to remain in the highest adjustment state, the lowest adjustment state, or between the highest and lowest adjustment states. When the holding part disengages from the slot 1213, the relative position of the lifting member 120 and the base module 110 is adjustable, facilitating the adjustment of the height of the lifting device 100. The mating direction of the holding part 1423 and the slot 1213 is simple and efficient, which improves the user experience.

[0066] Please see also Figure 14 In some embodiments, the holding part 1423 has a first holding surface 1421 and a second holding surface 1422 that are disposed facing the card slot 1213 and bent and connected together, and the first holding surface 1421 and the second holding surface 1422 are respectively inclined relative to the inner wall of the card slot 1213.

[0067] Understandably, the first holding surface 1421 intersects with the second holding surface 1422.

[0068] Understandably, the first card holding surface 1421 and the second card holding surface 1422 are positioned relative to the card slot 1213.

[0069] In this embodiment, the first retaining surface 1421 and the second retaining surface 1422 are respectively inclined relative to the inner wall of the slot 1213 to guide the retaining part 1423 into or out of the slot 1213, facilitating the engagement of the retaining part 1423 with the slot 1213 or the separation of the retaining part 1423 from the slot 1213. During the lifting process of the lifting device 100, under the drive of the drive part 141, the first retaining surface 1421 and the second retaining surface 1422 help guide the retaining part 1423 out of the slot 1213, thereby unlocking the drive member 140 and the lifting member 120, facilitating the movement of the lifting member 120 relative to the base 111. When the lifting device 100 moves to a specific height, with the assistance of the second elastic member 160, the first retaining surface 1421 and the second retaining surface 1422 help guide the retaining part 1423 into the slot 1213, thereby locking the driving member 140 and the lifting member 120, which facilitates limiting the relative position of the lifting member 120 and the base 111.

[0070] Optionally, please also see Figure 15 and Figure 16 In some embodiments, the card slot 1213 has a first inclined surface 1211 and a second inclined surface 1212 disposed opposite to each other along the moving direction. The first inclined surface 1211 and the second inclined surface 1212 are respectively inclined relative to the inner sidewall of the card slot 1213 to guide the card holding part 1423 into the card slot 1213.

[0071] In this embodiment, the first inclined surface 1211 and the second inclined surface 1212 facilitate guiding the holding part 1423 into or out of the slot 1213, improving the smoothness of separation and connection between the holding part 1423 and the slot 1213, and making it easier for the user to adjust the relative position of the lifting member 120 and the base module 110, thereby improving the user experience.

[0072] Optionally, in some embodiments, the first mating part 121 is a first magnetic attraction part, and the second mating part 142 is a second magnetic attraction part; wherein, during the process of the lifting device 100 rising, the second magnetic attraction part is driven to separate from the first magnetic attraction part by the driving part 141, and the first elastic member 130 in the deformed state can cause the lifting member 120 to move in a direction away from the base module 110, so that the lifting device 100 is in the highest adjustment state; when the lifting device 100 is in the highest adjustment state, or during the process of the lifting device 100 falling, the second magnetic attraction part can also move towards the first magnetic attraction part, and the second magnetic attraction part and the first magnetic attraction part are magnetically attracted to each other, so that the second magnetic attraction part and the first magnetic attraction part are connected.

[0073] In this embodiment, the first mating part 121 is configured as a first magnetic attraction part, and the second mating part 142 is configured as a second magnetic attraction part. The second magnetic attraction part moves towards or away from the first magnetic attraction part under the drive of the driving part 141. Specifically, when the second magnetic attraction part moves towards the first magnetic attraction part, it magnetically attracts the first magnetic attraction part, thus connecting them and fixing the relative position of the lifting member 120 and the base module 110. This allows the lifting device 100 to remain in the highest adjustment state, the lowest adjustment state, or between the highest and lowest adjustment states. Conversely, when the second magnetic attraction part moves away from the first magnetic attraction part under the drive of the driving part 141, and the driving force of the driving part 141 is greater than the magnetic attraction force between the second and first magnetic attraction parts, the second magnetic attraction part separates from the first magnetic attraction part. This allows the relative position of the lifting member 120 and the base module 110 to be adjustable, facilitating the adjustment of the height of the lifting device 100. The method of connecting and separating the first mating part 121 and the second mating part 142 by setting two magnetic components is simple and efficient, which helps to improve the user experience.

[0074] Optionally, in some other embodiments, two objects with a high coefficient of friction can be provided at the ends of the first mating part 121 and the second mating part 142. The first mating part 121 and the second mating part 142 can be connected by the friction between them. The second mating part 142 can be moved away from the first mating part 121 by the driving part 141, thereby separating the first mating part 121 and the second mating part 142.

[0075] Please see also Figures 1 to 16This application also provides a fan 200, which includes a lifting device 100 and an air outlet device 210 provided in this application. The air outlet device 210 is installed on one side of the lifting member 120, and the lifting device 100 is used to raise and lower the air outlet device 210.

[0076] Understandably, the air outlet device 210 is installed on the side of the lifting member 120 away from the base 111.

[0077] In this embodiment, the fan 200 includes a lifting device 100 and an air outlet device 210 provided in this application. The lifting device 100 is used to raise and lower the air outlet device 210 to adjust its height, thereby meeting the user's needs for the air outlet device 210 to be at different heights. The lifting device 100's method of adjusting the height of the lifting component 120 is simple, time-saving, and labor-saving, which helps improve the user experience.

Fan 200 includes, but is not limited to, circulating fans, tower fans, etc. In this embodiment and below, fan 200 is only used as a tower fan for illustrative purposes.
