Description

Technical Field

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

[0002] Most fans have a relatively fixed connection between the fan head and the body, and it is usually not convenient to adjust the position of the fan head to adapt to different usage scenarios.

[0003] In related technologies, some fans can adjust their height by removing and installing the body rod or extending and retracting the body. However, this adjustment method is relatively complex, and due to the basic length of the body rod, the height of the fan head remains at a relatively high level, resulting in limited adjustment effectiveness and making it difficult to meet the needs of more varied usage scenarios. Utility Model Content

[0004] Therefore, it is necessary to provide a fan that can easily adjust the height of the fan head and broaden its application scenarios to address the above problems.

[0005] A fan, the fan comprising:

[0006] fuselage boom;

[0007] The machine head and the bracket, the bracket having a first connecting part and a second connecting part, the first connecting part being rotatably connected to the machine body rod, and the second connecting part being rotatably connected to the machine head; the bracket is configured to be able to rotate about a first rotation axis through the first connecting part, and the second connecting part is spaced apart from the first rotation axis;

[0008] The machine head has an unfolded position and a folded position, and can be rotated via the bracket to switch between the unfolded position and the folded position; the machine head has an air outlet and an air inlet. In the folded position, the machine head is located around the body rod, one of the air inlet and the air outlet faces away from the body rod, and the other is at least partially not blocked by the body rod.

[0009] In one embodiment, in the folded position, the head is spaced apart from the body rod, and the air outlet faces away from the body rod.

[0010] In one embodiment, in the folded position, the distance between the head and the body rod is D, and D≥10mm.

[0011] In one embodiment, the first connecting portion has a locking surface, the fan includes a stop block located at one end of the rotation path of the first connecting portion, and the fan head is in the folded position when the locking surface abuts against the stop block.

[0012] In one embodiment, the fan further includes a locking mechanism disposed on the body rod and configured to lock the bracket in the unfolded position in a direction of rotation about the first rotation axis, and to operably release the lock.

[0013] In one embodiment, when the bracket switches from the unfolded position to the folded position, the first connecting portion rotates along a first direction;

[0014] The first connecting portion has a locking surface, and the locking mechanism includes a blocking member; the blocking member is movably disposed and configured to move to block the rotation path of the locking surface along the first direction of rotation when the bracket is in the unfolded position.

[0015] In one embodiment, the locking mechanism further includes an elastic member, the blocking member being configured to move along the locking direction to block the rotational path of the locking surface rotating along the first steering direction; the elastic member abuts against the blocking member and is configured to provide a driving force to drive the blocking member to move along the locking direction.

[0016] In one embodiment, the first connecting portion has a baffle rib forming the locking surface, and the baffle rib also has a sliding surface; in the first direction of rotation, the sliding surface is located upstream of the locking surface, and the sliding surface is connected to the upstream end of the locking surface in the locking direction; wherein the locking surface is parallel to the locking direction, and the sliding surface intersects the locking direction.

[0017] In one embodiment, the bracket includes a first connecting arm and a second connecting arm, both of which are connected to the first connecting portion and are respectively located on opposite sides of the body rod; the ends of the first connecting arm and the second connecting arm away from the first connecting portion are respectively formed as the second connecting portion, and the machine head is located between the second connecting portion of the first connecting arm and the second connecting portion of the second connecting arm.

[0018] In one embodiment, the fuselage pole is configured to be telescopic to change its length.

[0019] In one embodiment, the fuselage rod includes a rod body and a rotating base;

[0020] The rotating base is rotatably mounted on the rod body about the height of the fan, and the bracket is rotatably connected to the rotating base through the first connecting part.

[0021] The aforementioned fan's head can be folded to the side of the main body by rotating the bracket, reducing its height. One of its air inlets and outlets faces away from the main body, allowing for normal air intake or exhaust, while the other outlet allows air to be supplied or intake through at least the unobstructed portion. In other words, the fan head can be lowered from the original height of the main body by folding the bracket, and its normal airflow angle is maintained by rotating relative to the bracket. Thus, when the fan head is unfolded, it can be used as a floor fan. When the fan head is folded, its height can be reduced to below the minimum height of the main body, allowing it to be used as a table fan, thus broadening its application scenarios. Furthermore, this method of lowering the fan head height does not require disassembling the main body, making it more convenient. Attached Figure Description

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

[0047] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0048] Furthermore, where the term "and / or" appears, it merely describes the relationship between related objects and indicates that three relationships can exist. For example, A and / or B can represent the relationship between A and B: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this document generally indicates an "or" relationship between the related objects before and after it. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature specified with "first" or "second" may explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, four, five, etc., unless otherwise explicitly specified.

[0049] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0050] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0051] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0052] Please see Figures 1 to 6An embodiment of this application provides a fan 100, including a body rod 10, a fan head 20, and a bracket 30. The bracket 30 has a first connecting portion 31 and a second connecting portion 33. The first connecting portion 31 is rotatably connected to the body rod 10, and the second connecting portion 33 is rotatably connected to the fan head 20. The bracket 30 is configured to rotate about a first rotation axis 310 via the first connecting portion 31, and the second connecting portion 33 is spaced apart from the first rotation axis 310. The fan head 20 has an extended position (e.g., ...). Figure 1 , 2 (as shown) and folding position (as shown) Figure 3 As shown), and can rotate relative to the body rod 10 via the bracket 30 to switch between an unfolded position and a folded position. The head 20 has an air outlet 21 and an air inlet 23. In the folded position, the head 20 is located around the body rod 10, with one of the air inlet 23 and the air outlet 21 facing away from the body rod 10, and the other at least partially not obstructed by the body rod 10.

[0053] Fan 100 can be, but is not limited to, a circulating fan. Understandably, the direction in which the first rotation axis 310 is located is the first direction, which is configured relative to the height direction of fan 100 (e.g., ...). Figure 1 The bracket 30 is able to rotate around the first rotation axis 310, so as to flip and fold relative to the body rod 10. Therefore, when the bracket 30 rotates around the first rotation axis 310, the second connecting part 33, which is spaced apart from the first rotation axis 310, rises and falls in the height direction of the fan 100, and correspondingly, the head 20 connected to the second connecting part 33 rises and falls accordingly.

[0054] Specifically, the fan head 20 of the fan 100 can rotate relative to the second connecting part 33 around the second rotation axis 330. The second rotation axis 330 can be parallel to the first direction, that is, the second rotation axis 330 and the first rotation axis 310 are parallel to each other and spaced apart. Furthermore, during the folding process of the bracket 30, since the fan head 20 and the bracket 30 are rotatably connected, the fan head 20 can maintain its angular stability by rotating relative to the bracket 30. That is, no matter what angle the bracket 30 rotates to, the fan head 20 can maintain a vertical angle. Accordingly, the fan head 20 can rotate to at least the unfolded position and the folded position, and can remain stable in both positions.

[0055] In the folded position, the air inlet 23 of the head unit 20 faces away from the body rod 10, and the air outlet 21 is not completely blocked by the body rod 10. The air inlet 23 can take in air normally, and the air outlet 21 can at least send air out through the unblocked part; or, the air outlet 21 of the head unit 20 faces away from the body rod 10, and the air inlet 23 is not completely blocked by the body rod 10. The air outlet 21 can send air out normally, and the air inlet 23 can at least take in air through the unblocked part.

[0056] The aforementioned fan 100 has a head unit 20 that can be folded to the side of the body pole 10 by rotating the bracket 30, thus reducing its height. One of its air inlet 23 and air outlet 21 faces away from the body pole 10 and can normally intake or exhaust air, while the other can at least exhaust or intake air through the unobstructed portion. In other words, the head unit 20 can be lowered from the original height of the body pole 10 by folding the bracket 30, and its normal airflow angle can be maintained by rotating relative to the bracket 30. Thus, when the head unit 20 is unfolded, the fan 100 can be used as a floor fan. When the head unit 20 is folded, its height can be reduced to below the minimum height of the body pole 10, allowing the fan 100 to be used as a table fan, thus broadening its application scenarios. Furthermore, this method of lowering the height of the head unit 20 does not require disassembling the body pole 10, making it more convenient.

[0057] Furthermore, in the folded position, the head 20 is spaced apart from the body rod 10, and the air outlet 21 faces away from the body rod 10.

[0058] The air outlet 21 faces away from the body rod 10, and the side it faces is the front side of the fan 100. In other words, in the folded position, the fan head 20 is located in front of the body rod 10, and the orientation of the fan head 20 remains unchanged before and after folding. Specifically, the air outlet 21 and air inlet 23 of the fan head 20 can be arranged opposite each other, with the air inlet 23 facing rearward, i.e., towards the body rod 10. The fan head 20 has a front grille at the air outlet 21 and a rear grille at the air inlet 23. When folded, the fan head 20 is spaced apart from the body rod 10, and the air inlet 23 is also spaced apart from the body rod 10, but is not blocked by the body rod 10. Correspondingly, the front grille is spaced apart from the body rod 10. Furthermore, in the projection in the front-rear direction, the air inlet 23 does not overlap with the body rod 10 at least partially.

[0059] Thus, the air inlet 23 is spaced apart from the body rod 10, allowing airflow to enter the air inlet 23 through the gap between them. At the same time, the air outlet 21 can deliver air without being obstructed by the body rod 10 and can deliver air forward normally, so that the fan 100 can still maintain high air delivery efficiency when the head 20 is folded by the bracket 30 and used as a table fan.

[0060] Furthermore, in the folded position, the distance between the head 20 and the body rod 10 is D, and D≥10mm.

[0061] Specifically, the distance D between the nose cone 20 and the fuselage rod 10 can be, but is not limited to, 10mm, 15mm, 20mm, 30mm, 50mm, etc., and is not specifically limited here. In the folded position, the distance between the nose cone 20 and the fuselage rod 10 can be the distance between the rear grille and the fuselage rod 10.

[0062] In this way, there can be a sufficient gap between the air inlet 23 and the body rod 10 to allow air to enter through the air inlet 23.

[0063] In some other embodiments, the fuselage rod 10 has an air guiding area that faces the air inlet 23 of the head 20 when the head 20 is in the folded position. The fuselage rod 10 has a flow guiding structure and / or a through air inlet 23 in the air guiding area for guiding air to the air inlet 23 of the head 20.

[0064] Please refer to the following: Figures 7 to 11 In some embodiments, the first connecting part 31 has a locking surface 311, the fan 100 includes a stop 51, the stop 51 is disposed at one end of the rotation path of the first connecting part 31, and the head 20 is in a folded position when the locking surface 311 abuts against the stop 51.

[0065] Specifically, when the bracket 30 is switched from the unfolded position to the folded position, the first connecting part 31 rotates along the first direction. When the bracket 30 is switched from the folded position to the unfolded position, the first connecting part 31 rotates along the second direction. When the first connecting part 31 rotates along the first direction until the locking surface 311 abuts against the stop block 51, it is at one end of its rotation path and is blocked by the stop block 51 and cannot continue to rotate.

[0066] Thus, with the stop block 51 blocking it, the machine head 20 can be stably folded under the action of gravity, and the position of the stop block 51 can control the size of the gap between the machine head 20 and the body rod 10 after folding.

[0067] In some embodiments, the bracket 30 includes a first connecting arm 35 and a second connecting arm 37. The first connecting arm 35 and the second connecting arm 37 are both connected to the first connecting portion 31 and are respectively located on opposite sides of the body rod 10. The ends of the first connecting arm 35 and the second connecting arm 37 away from the first connecting portion 31 are respectively formed as second connecting portions 33. The head 20 is located between the second connecting portions 33 of the first connecting arm 35 and the second connecting portions 33 of the second connecting arm 37.

[0068] Understandably, the support 30 may also include a rotating part, which is rotatably mounted through the body rod 10 and forms a first connecting part 31. A first connecting arm 35 and a second connecting arm 37 are respectively connected to opposite ends of the rotating part. The first connecting arm 35 and the second connecting arm 37 are spaced apart, and the machine head 20 is installed between them.

[0069] Thus, when the head 20 is unfolded and in use, the head 20 is accommodated between the two connecting arms. When the head 20 is folded to the front of the body rod 10, the two connecting arms can also provide clearance for the body rod 10, so that the head 20 can be fully folded to prevent the bracket 30 and the body rod 10 from interfering with each other during the folding process.

[0070] In some embodiments, the fuselage pole 10 is configured to be telescopic to change its length.

[0071] Understandably, the fuselage pole 10 is capable of at least one extension, that is, it can switch between at least two lengths through extension and retraction, and each length can remain stable.

[0072] In this way, the fan 100 can adjust its overall height by extending and retracting the body rod 10. The combination of the extension and retraction of the body rod 10 and the rotation of the bracket 30 helps to expand the height adjustment range of the fan 100.

[0073] Please refer to the following: Figures 12 to 14 In some embodiments, the fan 100 further includes a locking mechanism 50 disposed on the body rod 10 and configured to lock the bracket 30 in the unfolded position in the direction of rotation about the first rotation axis 310 and to operably release the lock.

[0074] The locking mechanism 50 can at least lock the bracket 30 in the unfolded position. That is, under the locking of the locking mechanism 50, the bracket 30 in the unfolded position cannot rotate normally through the first connecting part 31, and therefore cannot be switched to the folded position. Moreover, the lock can be released by operation. On the other hand, after the lock is released, the bracket 30 can be rotated to the folded position by the user's operation or by gravity, and can be stably held in the folded position by gravity.

[0075] Thus, through the cooperation of the locking mechanism 50 and the bracket 30, the fan head 20 can be stably positioned when the fan 100 is in use. When it is necessary to fold the fan head 20, the user can unlock it by operating the locking mechanism 50.

[0076] Furthermore, the locking mechanism 50 includes a blocking member 52. The blocking member 52 is movably disposed and configured to move to block the locking surface 311 from rotating along the first direction when the bracket 30 is in the extended position.

[0077] Understandably, the locking surface 311 is in different positions as the first connecting part 31 rotates. When the bracket 30 is in the unfolded position, the locking surface 311 rotates to the vicinity of the blocking member 52, and the blocking member 52 can move onto the rotation path of the locking surface 311, preventing the bracket 30 from rotating back to the folded position.

[0078] The external force that drives the blocking member 52 to move can be, but is not limited to, the elastic force provided to the spring, gravity, or the external force applied by the user.

[0079] Thus, by abutting the locking surface 311, the blocking member 52 can stably keep the bracket 30 in the unfolded position, and the user only needs to drive the blocking member 52 to move in the opposite direction of the lock to release the lock.

[0080] In some embodiments, the locking mechanism 50 further includes an elastic member 53, and the blocking member 52 is configured to be oriented along the locking direction (e.g., Figure 13 The element 52 moves in the Y direction (as shown) onto a rotational path that blocks the locking surface 311 from rotating in the first direction. The elastic element 53 abuts against the blocking element 52 and is configured to provide a driving force to move the blocking element 52 in the locking direction.

[0081] Understandably, the elastic element 53 may be a spring and pre-compressed to provide driving force for the movement of the driving stop element 52 in the locking direction.

[0082] Thus, when the first connecting part 31 is rotated into place, that is, when the bracket 30 is in the unfolded position, the blocking member 52 can automatically move along the locking direction to lock the bracket 30.

[0083] Please refer to the following: Figures 15 to 16 In some embodiments, the locking mechanism 50 further includes a housing 55 and a button 57. The housing 55 is disposed on the body rod 10 and has a pressing channel 551 extending in the locking direction. The button 57 is disposed on the pressing channel 551 and is movable along the pressing channel 551. A blocking member 52 is disposed on the button 57.

[0084] Understandably, button 57 can reciprocate along the pressing channel 551. When it moves into the pressing channel 551, it can drive the blocking member 52 on it to move in the opposite direction to the locking direction, so as to release its obstruction of the locking surface 311. Specifically, the blocking member 51 is provided on the housing 55 and can be integrally formed with the housing 55.

[0085] Thus, the locking mechanism 50 can be mounted on the body rod 10 via its housing 55. The button 57 can move along the pressing channel 551 to achieve a reciprocating action in the locking direction, thereby driving the blocking member 52 to reciprocate in the locking direction. The user can overcome the elastic force by pressing the button 57, and the blocking member 52 of the drive assembly can be released from locking. In addition, the housing 55 is relatively closed and has high support strength, which can provide high-strength locking through the blocking member 52, improving the reliability of the locking mechanism 50.

[0086] Furthermore, one end of the pressing channel 551 in the locking direction is an opening connecting to the outside. One end of the button 57 in the locking direction is located inside the pressing channel 551, and the other end is exposed outside the housing 55 from the opening and formed as a pressing end 571. One end of the elastic member 53 abuts against the blocking member 52, and the other end abuts against the bottom of the pressing channel 551 away from the opening.

[0087] Button 57 may be partially located within the pressing channel 551, and its length within the pressing channel 551 can be changed during movement. The pressing end 571 of button 57 is always exposed outside the housing 55 for user pressing, providing a force to drive button 57 toward the bottom of the pressing channel 551. The elastic element 53 provides a force between the blocking element 52 and the bottom of the pressing channel 551, driving the blocking element 52 away from the bottom of the pressing channel 551; the elastic element 53 is always in a compressed state during normal use.

[0088] In this way, the user and the elastic element 53 can respectively provide a pair of opposite forces to the button 57 so that it can reciprocate normally, thereby unlocking and locking respectively.

[0089] Specifically, the housing 55 may also have a mounting post 552, which is located at the bottom of the pressing channel 551 away from the opening. The elastic element 53 is a spring and is sleeved on the mounting post 552. In this way, the elastic element 53 can be accurately positioned and installed.

[0090] In some embodiments, the housing 55 further has an active hole 553 communicating with the pressing channel 551, and the active hole 553 extends in the locking direction. The blocking member 52 extends out of the housing 55 through the active hole 553 and moves along the active hole 553 with the button 57 as the button 57 moves along the pressing channel 551.

[0091] In other words, the blocking member 52 can be partially located outside the housing 55 through the movable hole 553, so as to block the rotation path of the locking surface 311. At the same time, the blocking member 52 can also move through the movable hole 553 to realize the process of locking and unlocking by movement.

[0092] Thus, the blocking component 52 can normally perform its movement locking and unlocking functions. At the same time, under the limitation of the movable hole 553, its movement path is more accurate. The small movement gap between the blocking component 52 and the sliding groove wall of the housing 55 helps to ensure that the movement of the blocking component 52 is smooth and accurately positioned without any play.

[0093] In some embodiments, the button 57 has a socket 572, into which a blocking member 52 is inserted. The blocking member 52 may be, but is not limited to, a columnar blocking member 52. Furthermore, the button 57 may also have a limiting hole for mounting a spring.

[0094] Thus, the blocking member 52 can cooperate with the button 57 during the assembly process through subsequent plugging. Specifically, the button 57 can be first assembled into the pressing passage of the housing 55, with the insertion hole 572 aligned with the movable hole 553, and then the blocking member 52 can be inserted into the insertion hole 572 through the movable hole 553.

[0095] In some embodiments, the first connecting portion 31 has a stop rib 313, which forms a locking surface 311 and also has a sliding surface 315. In the first direction of rotation, the sliding surface 315 is located upstream of the locking surface 311 and is connected to the upstream end of the locking surface 311 in the locking direction. The locking surface 311 is parallel to the locking direction, and the sliding surface 315 intersects the locking direction.

[0096] Understandably, when the blocking member 52 moves in the direction opposite to the locking direction, it will disengage from the locking surface 311 when it reaches the upstream end of the locking surface 311 in the locking direction. Once the blocking member 52 has officially disengaged from the locking surface 311, it can naturally move onto the upstream sliding surface 315. Conversely, the blocking member 52 can slide from the sliding surface 315 to the blocking locking surface 311 during the transition to the unfolded position. In other words, during the transition of the bracket 30 between the unfolded and folded positions, the blocking member 52 can slide along the sliding surface 315. When transitioning to the unfolded position, the blocking member 52 cuts from the sliding surface 315 into the blocking locking surface 311. When releasing the lock on the unfolded position, the blocking member 52 slides from the locking surface 311 back along the sliding surface 315.

[0097] The sliding surface 315 can be an arc surface, an inclined surface, or a combination of both, as long as it allows the blocking member 52 to slide smoothly; no specific limitation is made here.

[0098] Thus, when the lock on the unfolded position is released, the blocking member 52, after being disengaged from the locking surface 311, can automatically slide along the sliding surface 315 as the bracket 30 rotates. When the bracket 30 rotates to the unfolded position, the blocking member 52 can disengage from the sliding surface 315 and, under the action of the elastic member 53, quickly move in the locking direction to block the locking surface 311.

[0099] Please refer to the following: Figures 17 to 20 In some embodiments, the frame rod 10 includes a rod body 11 and a rotating seat 131. The rotating seat 131 is rotatably disposed on the rod body 11 about the height direction of the fan 100. The bracket 30 is rotatably connected to the rotating seat 131 through the first connecting part 31.

[0100] Specifically, the rod 11 includes a connected main body 111 and a telescopic part 115. The main body 111 has a telescopic cavity 1111, which extends along the height direction of the fan 100. The telescopic part 115 is connected to the main body 111 and is configured to extend and retract relative to the main body 111 through the telescopic cavity 1111. The rotating seat 131 is part of the oscillation mechanism 13 that realizes the oscillation of the fan 100. In addition, the oscillation mechanism 13 also includes an oscillation mounting part 113, which is located around the periphery of the main body 111 and has a mounting cavity 1133. The rotating seat 131 is rotatably disposed in the mounting cavity 1133 about the height direction of the fan 100.

[0101] Specifically, the locking mechanism 50 is also assembled onto the rotating seat 131 through its housing 55. A support column 1311 is formed on the rotating seat 131, and a mating column 554 that cooperates with the support assembly is on the housing 55.

[0102] Thus, the fan 100 can achieve the oscillation function via the rotating base 131, and since the oscillation assembly 113 is located on the periphery of the main body 111, the space occupied by the oscillation mechanism 13 in the height direction of the fan 100 is reduced, and the oscillation mechanism 13 and the main body 111 can be arranged radially. The space of the fan 100 in the height direction can be more fully utilized for the extension and retraction of the main body 111.

[0103] Please refer to the following: Figure 21 In some embodiments, the oscillating assembly 113 includes a mounting base 1131. The mounting base 1131 has a rotating column 11311 extending along the height direction of the fan 100. The rotating base 131 has a rotating hole 1313 that mates with the rotating column 11311. The rotating base 131 is sleeved on the rotating column 11311 through the rotating hole 1313. Understandably, the rotating base 131 is located on the mounting base 1131 and is capable of rotating about the rotating column 11311 as a rotation axis.

[0104] In this way, the rotating base 131 can achieve stable rotation through the rotating column 11311, thereby improving the stability of the fan 100 oscillation.

[0105] Furthermore, a groove 11313 is formed in one of the cavity walls of the rotating column 11311 and the rotating hole 1313, and a buckle 1315 that engages with the groove 11313 is formed in the other. The groove 11313 and the buckle 1315 engage and form a limit in the height direction of the fan 100.

[0106] Specifically, a groove 11313 can be formed around the rotating column 11311 along the axial direction, and a buckle 1315 is formed in the cavity wall of the rotating hole 1313. Understandably, during installation, the rotating seat 131 can be sleeved on the rotating column 11311 along the height direction of the fan 100, and during the installation process, the rotating seat 131 gradually moves downward until its buckle 1315 is engaged in the groove 11313 of the mounting seat 1131.

[0107] Thus, after the rotating base 131 is installed, the engagement of the clip 1315 and the slot 11313 can reduce the probability of it detaching from the mounting base 1131, which helps to improve the assembly stability of the fan 100.

[0108] Please refer to the following: Figure 22 In some embodiments, the swaying mechanism 13 further includes a swaying drive 133, which is disposed in the mounting cavity 1133 and is connected to the rotating seat 131 in a transmission manner.

[0109] Specifically, the sway assembly 113 also includes a housing that connects to the main body 111, and a mounting cavity 1133 is formed inside the housing. The mounting cavity 1133 also has an assembly post 1135, and the mounting seat 1131 is mounted on the assembly post 1135.

[0110] Thus, the oscillation drive 133 can drive the rotating base 131 to rotate, thereby enabling the fan 100 to oscillate. In addition, the oscillation drive 133 is located in the mounting cavity 1133 of the oscillation assembly 113, and is also located on the periphery of the main body 111, which can reduce the occupation of height space.

[0111] Furthermore, the oscillating drive 133 includes a driver 1331 and a drive gear 1333. The drive gear 1333 is engaged with the output shaft of the driver 1331, and the rotating seat 131 has a mating tooth 1317 that meshes with the drive gear 1333.

[0112] Specifically, the rotating base 131 is configured to form a mating tooth 1317 around the height direction of the fan 100. The drive shaft of the driver 1331 is arranged along the height direction of the fan 100. Correspondingly, the axial direction of the drive gear 1333 is also arranged along the height direction of the fan 100 and is anti-rotationally engaged with the output shaft of the driver 1331, and meshes with the mating tooth 1317.

[0113] Thus, the driver 1331 can drive the rotating seat 131 to rotate through the meshing of the drive gear 1333 and the mating gear 1317. Depending on actual needs, the desired oscillation speed can be obtained by appropriately reducing the speed of the driver 1331.

[0114] Specifically, the driver 1331 can be, but is not limited to, a motor. The driver 1331 can be connected to a mounting base 1131, which has a limiting post 1137 for limiting the drive gear 1333.

[0115] In some embodiments, the first connecting portion 31 has a first rotational mating surface 317 perpendicular to the first rotation axis 310, and the body rod 10 has a second rotational mating surface 1319 perpendicular to the first rotation axis 310. The first rotational mating surface 317 and the second rotational mating surface 1319 are arranged facing each other. Specifically, the second rotational mating surface 1319 is located on the rotating seat 131.

[0116] The fan 100 also includes a damping plate 71, which is disposed between the first rotating mating surface 317 and the second rotating mating surface 1319 and can contact the first rotating mating surface 317 and the second rotating mating surface 1319 simultaneously.

[0117] Understandably, the damping plate 71 provides damping force for the relative rotation between the first rotating mating surface 317 and the second rotating mating surface 1319, that is, it provides damping force for the rotation of the support 30 relative to the fuselage rod 10. The damping plate 71 can provide either linear damping adjustment or instantaneous damping adjustment, which is not specifically limited here.

[0118] Thus, the damping plate 71 can provide damping force for the folding of the fan head 20 of the fan 100, reducing the probability of damage caused by folding too quickly.

[0119] Specifically, the first rotating mating surface 317 and / or the second rotating mating surface 1319 have mounting grooves 319, and the damping plate 71 is installed in the mounting grooves 319. The fan 100 also has a shaft screw 72, which passes through the two first rotating mating surfaces 317 and the two second rotating mating surfaces 1319, connects the first connecting part 31 and the rotating seat 131 and is fixed by a nut 73. The shaft screw 72 also serves as the shaft for both.

[0120] For ease of understanding, the assembly process of the fan 100 is briefly described below: 1. First, connect the fan head 20 and the bracket 30 rotatably together using screws or clips 1315; 2. Assemble the housing 55 of the locking mechanism 50 with the rotating seat 131: Insert the support post 1311 on the rotating seat 131 into the mating post 554 of the housing 55 (interference fit), so that the housing 55 is embedded in the rotating seat 131; 3. Assemble the bracket 30 and the rotating seat 131: Align the screw holes of the bracket 30 with the screw holes of the rotating seat 131, then pass the rotating shaft screw 72 through the screw holes on the bracket 30 and the rotating seat 131, and then use the nut 73 to lock the bracket 30 and the rotating seat 131 together; 4. Assemble the button 57 of the locking mechanism 50 with the housing 55: Fit the spring 53, which is the elastic element, onto the housing 55. 5. Mounting post 552 of 5, then insert button 57 into pressing channel 551, with appropriate interference fit, so that the insertion hole 572 of button 57 is aligned with the movable hole 553 of housing 55. At this time, button 57 is embedded in housing 55. Then insert blocking member 52 horizontally into insertion hole 572 of button 57 (interference fit between blocking member 52 and insertion hole 572) and make blocking member 52 located in movable hole 553 of housing 55. Blocking member 52 passes through housing 55. 5. Connect rotating seat 131 and rod 11: Align the output shaft of driver 1331 with the gear hole of drive gear 1333 and insert it, so that driver 1331 and drive gear 1333 are interference fitted together. Then, align the screw hole of driver 1331 with the screw post at the lower end of mounting seat 1131 and fix driver 1331 to mounting seat 1131 with screws. After the driver 1331 is connected to the mounting base 1131, it is placed in the mounting cavity 1133 of the rod body 11. At this time, the screw holes of the mounting base 1131 are aligned with the screw posts in the mounting cavity 1133, and then the mounting base 1131 is fixed with screws. After the mounting base 1131 is fixed, the rotating hole 1313 of the rotating seat 131 cooperates with the rotating column 11311 of the mounting base 1131, so that the slot 11313 on the rotating column 11311 is engaged with the buckle 1315 of the rotating seat 131. At the same time, the mating teeth 1317 on the lower periphery of the rotating seat 131 are aligned and meshed with the drive gear 1333. When the whole machine is running, the driver 1331 drives the driven seat 131 through the drive gear 1333; 6. Finally, the two ends of the telescopic part 115 are screwed into the main body 111 and the chassis 90 respectively.

[0121] When button 57 is pressed, the blocking member 52 disengages from the locking surface 311 of the bracket 30, allowing the bracket 30 to move. Rotating the bracket 30 causes the blocking member 52 to move along the sliding surface 315 within the bracket 30. The bracket 30, along with the head unit 20, is flipped forward to the front of the body rod 10 until the locking surface 311 of the baffle 313 abuts against the stop block 51, ultimately allowing the head unit 20 to be mounted against the front of the body rod 10. Simultaneously, a gap (not less than 10mm) is maintained between the rear grille corresponding to the air inlet 23 of the head unit 20 and the body rod 10, ensuring normal airflow. Furthermore, the height of the body can be lowered by extending and retracting the body rod 10 to accommodate tabletop placement.

[0122] When the user wants to unfold the fan 100, the telescopic part 115 is then pulled down to the bottom. Finally, the bracket 30 is flipped until the blocking member 52 disengages from the sliding surface 315 of the bracket 30. At this point, under the action of the spring, the blocking member 52 and the button 57 spring outward, causing the blocking member 52 to contact the locking surface 311 of the bracket 30, thereby restricting the movement of the bracket 30 and completing the unfolding of the entire fan 100.

[0123] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0124] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
