Description

Technical Field

[0001] The present application relates to the field of electrical equipment technology, and in particular to a fan. Background Art

[0002] For most fans, the connection between the head and the body is relatively fixed, and it is usually not possible to easily adjust the position of the head to adapt to different usage scenarios.

[0003] In the related art, some fans can adjust their height by disassembling the fuselage rod, telescoping the fuselage, etc. However, this adjustment method is relatively complicated, and is limited by the basic length of the fuselage rod. The height of the head is still maintained at a relatively high level, and the adjustment effect is limited, which is difficult to cope with more varied usage scenarios. Summary of the invention

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

[0005] A fan, comprising:

[0006] fuselage rod;

[0007] A machine head and a bracket, wherein the bracket has a first connection part and a second connection part, the first connection part is rotatably connected to the machine body rod, and the second connection part is rotatably connected to the machine head; the bracket is configured to be rotatable around a first rotation axis through the first connection part, and the second connection part is spaced apart from the first rotation axis;

[0008] The head has an unfolded position and a folded position, and can be rotated through the bracket to switch between the unfolded position and the folded position; the head has an air outlet and an air inlet, and in the folded position, the head is located on the peripheral side of the fuselage rod, one of the air inlet and the air outlet faces away from the fuselage rod, and the other is at least partially not blocked by the fuselage rod.

[0009] In one of the embodiments, in the folded position, the nose is spaced apart from the fuselage bar, and the air outlet faces away from the fuselage bar.

[0010] In one of the embodiments, in the folded position, the spacing dimension between the nose and the body rod is D, and D≥10 mm.

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

[0012] In one of the embodiments, the fan further comprises a locking mechanism, which is disposed on the body rod and is configured to lock the bracket in the unfolded position in a direction of rotation about the first rotation axis and to be operable to unlock the bracket.

[0013] In one embodiment, when the bracket is switched 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 arranged and configured to be able to move to a rotation path that blocks the locking surface from rotating along the first turning direction when the bracket is in the deployed position.

[0015] In one embodiment, the locking mechanism also includes an elastic member, and the blocking member is configured to be able to move along the locking direction to block the rotation path of the locking surface along the first turning direction; the elastic member abuts 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 retaining rib, the retaining rib forms the locking surface, and the retaining rib also has a sliding surface; in the first turn, the sliding surface is located upstream of the locking surface, and the sliding surface is connected to an end of the locking surface located upstream in the locking direction; wherein the locking surface is parallel to the locking direction, and the sliding surface intersects with the locking direction.

[0017] In one embodiment, the bracket includes a first connecting arm and a second connecting arm, the first connecting arm and the second connecting arm are both connected to the first connecting part and are respectively arranged on opposite sides of the fuselage rod; the ends of the first connecting arm and the second connecting arm away from the first connecting part are respectively formed as the second connecting part, and the nose is arranged between the second connecting part of the first connecting arm and the second connecting part of the second connecting arm.

[0018] In one of the embodiments, the fuselage rod is configured to be telescopic so as to change its length.

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

[0020] The rotating seat is rotatably arranged on the rod body around the height direction of the fan, and the bracket is rotatably connected to the rotating seat through the first connecting portion.

[0021] The head of the above-mentioned fan can be folded to the side of the fuselage rod by rotating the bracket, so that the self-lifting height is reduced, and one of its air inlet and air outlet is facing away from the fuselage rod and can normally take in or supply air, and the other can at least supply or take in air through the unblocked part. In other words, the height of the head can be lowered by folding the bracket on the basis of the original height of the fuselage rod, and its normal air supply angle can be maintained by rotating relative to the bracket. In this way, after the head is unfolded, the fan can be used as a floor fan. After the head is folded, its height can be reduced to lower than the minimum height of the fuselage rod, and the fan can be used as a table fan, and its usage scenarios are broadened. In addition, this method of lowering the height of the head does not require disassembly and assembly of the fuselage rod, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore it should not be understood as a limitation on the present application.

[0048] In addition, if the term "and / or" appears, "and / or" is merely a way to describe the association relationship between associated objects, and indicates that three relationships may exist, for example, A and / or B can represent the association relationship between A and B: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that there is an "or" relationship between the associated objects before and after it. If the terms "first" and "second" appear, these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, four, five, etc., unless otherwise clearly and specifically defined.

[0049] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0050] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0051] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, 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 implementation method.

[0052] See also Figures 1 to 6The fan 100 provided in one embodiment of the present application includes a body rod 10, a head 20 and a bracket 30. The bracket 30 has a first connection portion 31 and a second connection portion 33. The first connection portion 31 is rotatably connected to the body rod 10, and the second connection portion 33 is rotatably connected to the head 20. The bracket 30 is configured to be rotatable around a first rotation axis 310 through the first connection portion 31, and the second connection portion 33 is spaced apart from the first rotation axis 310. The head 20 has an unfolded position (such as Figure 1 , 2 shown) and the folded position (as Figure 3 The head 20 is shown in FIG. 1 , and can be rotated relative to the body rod 10 through the bracket 30 to switch between the unfolded position and the folded position. The head 20 has an air outlet 21 and an air inlet 23. In the folded position, the head 20 is located at the periphery of the body rod 10, one of the air inlet 23 and the air outlet 21 faces away from the body rod 10, and the other is at least partially not blocked by the body rod 10.

[0053] The fan 100 may be, but is not limited to, a circulation fan. It is understandable that the direction in which the first rotation axis 310 is located is the first direction, and the first direction is configured to be parallel to the height direction of the fan 100 (eg, Figure 1 The bracket 30 can rotate around the first rotation axis 310 to flip or fold relative to the body rod 10. Therefore, when the bracket 30 rotates around the first rotation axis 310, the second connection portion 33 spaced apart from the first rotation axis 310 is lifted or lowered in the height direction of the fan 100, and accordingly, the head 20 connected to the second connection portion 33 is lifted or lowered accordingly.

[0054] Specifically, the head 20 of the fan 100 can rotate relative to the second connection portion 33 around the second rotation axis 330, and 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. In addition, during the folding process of the bracket 30, since the head 20 and the bracket 30 are rotatably connected, the head 20 can maintain its angle stability by rotating relative to the bracket 30, that is, no matter what angle the bracket 30 rotates to, the head 20 can maintain a vertical angle. Accordingly, the head 20 can at least rotate to an unfolded position and a folded position, and can remain stable in these two positions.

[0055] In the folded position, the air inlet 23 of the nose 20 faces away from the fuselage pole 10, and the air outlet 21 is not completely blocked by the fuselage pole 10, the air inlet 23 can take in air normally, and the air outlet 21 can at least supply air to the outside through the unblocked portion; or, the air outlet 21 of the nose 20 faces away from the fuselage pole 10, and the air inlet 23 is not completely blocked by the fuselage pole 10, the air outlet 21 can supply air normally, and the air inlet 23 can at least take in air through the unblocked portion.

[0056] In the above-mentioned fan 100, the head 20 can be folded to the side of the fuselage rod 10 by rotating the bracket 30, so that the self-lifting height is reduced, and one of the air inlet 23 and the air outlet 21 can normally take in or supply air when facing away from the fuselage rod 10, and the other can at least supply or take in air through the unblocked part. In other words, the head 20 can lower the height of the head 20 by folding the bracket 30 on the basis of the original height of the fuselage rod 10, and maintain its normal air supply angle by rotating relative to the bracket 30. In this way, after the head 20 is unfolded, the fan 100 can be used as a floor fan. After the head 20 is folded, its height can be reduced to lower than the minimum height of the fuselage rod 10, and the fan 100 can be used as a table fan, and its use scenario is widened. In addition, this method of lowering the height of the head 20 does not require disassembly and assembly of the fuselage rod 10, which is more convenient.

[0057] Furthermore, in the folded position, the nose 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 fuselage bar 10, and the side it faces is the front side of the fan 100. In other words, in the folded position, the head 20 is located in front of the fuselage bar 10, and the direction of the head 20 remains unchanged before and after folding. Specifically, the air outlet 21 and the air inlet 23 of the head 20 can be arranged opposite to each other, and the air inlet 23 faces backward, that is, toward the fuselage bar 10. The head 20 is provided with a front mesh grille at the air outlet 21, and a rear mesh grille at the air inlet 23. After folding, the head 20 is spaced from the fuselage bar 10, and the air inlet 23 is spaced from the fuselage bar 10, and is not blocked by the fuselage bar 10. Accordingly, the front mesh grille is spaced from the fuselage bar 10. In addition, in the projection in the front-to-back direction, the air inlet 23 at least partially does not overlap with the fuselage bar 10.

[0059] In this way, the air inlet 23 is spaced apart from the body rod 10, and the air flow can enter the air inlet 23 from the gap between the two. At the same time, the air outlet 21 can deliver air without being blocked by the body rod 10 and deliver air forward normally, so that the fan 100 can still maintain a 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 spacing dimension between the nose 20 and the body rod 10 is D, and D≥10 mm.

[0061] Specifically, the spacing dimension D between the nose 20 and the fuselage bar 10 may be, but is not limited to, 10 mm, 15 mm, 20 mm, 30 mm, 50 mm, etc., which is not specifically limited herein. In the folded position, the spacing between the nose 20 and the fuselage bar 10 may be the spacing between the rear grille and the fuselage bar 10.

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

[0063] In some other embodiments, the fuselage bar 10 has an air guide area, and when the nose 20 is in the folded position, the air guide area faces the air inlet 23 of the nose 20. The fuselage bar 10 is configured with a guide structure and / or an air inlet 23 arranged therethrough in the air guide area to guide air to the air inlet 23 of the nose 20.

[0064] Please also read Figures 7 to 11 In some embodiments, the first connection portion 31 has a locking surface 311, and the fan 100 includes a stopper 51, which is disposed at one end of the rotation path of the first connection portion 31, and when the locking surface 311 abuts against the stopper 51, the head 20 is in a folded position.

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

[0066] In this way, under the resistance of the blocking block 51, the nose 20 can be stably in the folded position under the action of gravity, and the position of the blocking block 51 can control the size of the distance between the nose 20 and the fuselage 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 part 31, and are respectively arranged on opposite sides of the fuselage rod 10; the ends of the first connecting arm 35 and the second connecting arm 37 away from the first connecting part 31 are respectively formed as second connecting parts 33, and the nose 20 is arranged between the second connecting part 33 of the first connecting arm 35 and the second connecting part 33 of the second connecting arm 37.

[0068] It can be understood that the bracket 30 may also include a rotating part, which is rotatably installed in the fuselage rod 10 and formed as a first connecting part 31, and the first connecting arm 35 and the second connecting arm 37 are respectively connected to the opposite ends of the rotating part. The first connecting arm 35 and the second connecting arm 37 are arranged at intervals, and the head 20 is installed between the two.

[0069] In this way, when the nose 20 is unfolded for use, the nose 20 is accommodated between the two connecting arms. When the nose 20 is folded in front of the fuselage rod 10, the two connecting arms can also form a avoidance position for the fuselage rod 10, so that the nose 20 can be fully folded to prevent the bracket 30 and the fuselage rod 10 from interfering with each other during the folding process.

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

[0071] It can be understood that the fuselage rod 10 can be extended and retracted for at least one section, that is, it can be switched between at least two lengths through extension and retraction, and each length can be stably maintained.

[0072] In this way, the fan 100 can adjust its entire height by extending and retracting the body rod 10. The fan 100 combines the two adjustment methods of extending and retracting the body rod 10 and rotating the bracket 30, which helps to expand the adjustment range of the fan 100 height.

[0073] Please also read Figure 12 to Figure 14 In some embodiments, the fan 100 further includes a locking mechanism 50, which is disposed on the body rod 10 and is configured to lock the bracket 30 in the unfolded position in a direction of rotation around the first rotation axis 310 and to be operable to unlock the bracket 30.

[0074] The locking mechanism 50 can at least lock the bracket 30 in the unfolded position, that is, when the locking mechanism 50 is locked, the bracket 30 in the unfolded position cannot be normally rotated through the first connecting portion 31, and cannot be switched to the folded position, and 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 under the operation of the user or the action of gravity, and can be stably in the folded position under the action of gravity.

[0075] In this way, through the cooperation between the locking mechanism 50 and the bracket 30, when the fan 100 is used, the head 20 can stabilize the current position. When the head 20 needs to be folded, 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 arranged and configured to move to a rotation path that blocks the locking surface 311 from rotating along the first turning direction when the bracket 30 is in the unfolded position.

[0077] It can be understood that the locking surface 311 is in different positions as the first connecting portion 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 to the rotation path of the locking surface 311 to prevent the bracket 30 from rotating back to the folded position.

[0078] The external force driving the blocking member 52 to move may be, but is not limited to, an elastic force provided by a spring, gravity, or an external force applied by a user.

[0079] In this way, the blocking member 52 can stabilize the bracket 30 in the unfolded position by abutting against the locking surface 311 , and unlocking the locking member 52 only requires the user to drive the blocking member 52 to move in the opposite direction of the locking.

[0080] In some embodiments, the locking mechanism 50 further includes an elastic member 53, and the blocking member 52 is configured to be able to move along the locking direction (eg, Fig.13 The elastic member 53 abuts against the blocking member 52 and is configured to provide a driving force for driving the blocking member 52 to move along the locking direction.

[0081] It can be understood that the elastic member 53 can be a spring and be pre-compressed to provide a driving force for driving the blocking member 52 to move along the locking direction.

[0082] In this way, when the blocking member 52 is rotated to the first connecting portion 31 , that is, when the bracket 30 is in the unfolded position, the blocking member 52 is automatically driven to move along the locking direction to lock the bracket 30 .

[0083] Please also read Figure 15 to Figure 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 along the locking direction. The button 57 is disposed on the pressing channel 551 and can move along the pressing channel 551. The blocking member 52 is disposed on the button 57.

[0084] It can be understood that the button 57 can reciprocate along the pressing channel 551. When it moves toward the pressing channel 551, it can drive the blocking member 52 thereon to move in the direction opposite to the locking direction to release its blocking 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] In this way, the locking mechanism 50 can be installed on the body rod 10 through its housing 55, and the button 57 can move along the pressing channel 551 to achieve reciprocating motion 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 driving group is unlocked. In addition, the housing 55 is relatively closed and has a large supporting strength, and can provide high-strength locking through the blocking member 52, thereby improving the reliability of the locking mechanism 50.

[0086] Furthermore, one end of the pressing channel 551 in the locking direction is an opening connected to the outside. One end of the button 57 in the locking direction is located in the pressing channel 551, and the other end is exposed from the opening to the outside of the housing 55 and forms 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] The button 57 may be partially located in the pressing channel 551, and the length of the button 57 located in the pressing channel 551 may be changed when the button 57 is moved. The pressing end 571 of the button 57 is always exposed outside the housing 55, so that the user can press the button 57 to provide a force to drive the button 57 toward the bottom of the pressing channel 551. The elastic member 53 can provide a force between the blocking member 52 and the bottom of the pressing channel 551 to drive the blocking member 52 away from the bottom of the pressing channel 551, and the elastic member 53 can be in a compressed state at all times during normal use.

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

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

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

[0091] In other words, the blocking member 52 can be partially outside the housing 55 through the movable hole 553 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 achieve the process of locking and unlocking by movement.

[0092] In this way, the blocking member 52 can normally realize its function of moving locking and unlocking, and at the same time, its moving path is more accurate under the limit of the movable hole 553. The movement gap between the blocking member 52 and the sliding groove wall of the housing 55 is small, which helps to ensure that the movement of the blocking member 52 is not stuck and is accurately positioned without empty position.

[0093] In some embodiments, the button 57 has an insertion hole 572, and the blocking member 52 is inserted into the insertion hole 572. The blocking member 52 may be, but is not limited to, a columnar blocking member 52. In addition, the button 57 may also have a limiting hole, and the limiting hole is used to install a spring.

[0094] In this way, the blocking member 52 can be matched with the button 57 in the assembly process by subsequent plugging. Specifically, the button 57 can be first assembled into the pressing hole of the housing 55, and the insertion hole 572 is aligned with the movable hole 553, and then the blocking member 52 is inserted into the insertion hole 572 through the movable hole 553.

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

[0096] It can be understood that when the blocking member 52 moves in the direction opposite to the locking direction, when it moves to the upstream end of the locking surface 311 in the locking direction, the blocking member 52 is about to disengage from the locking surface 311. When the blocking member 52 formally disengages from the locking surface 311, the blocking member 52 can naturally move to the sliding surface 315 located upstream. On the contrary, the blocking member 52 can slide from the sliding surface 315 to the blocking locking surface 311 during the process of switching to the unfolded position. In other words, during the process of the bracket 30 switching between the unfolded position and the folded position, the blocking member 52 can slide along the sliding surface 315. When switching to the unfolded position, the blocking member 52 cuts into the blocking locking surface 311 from the sliding surface 315. When the lock of the unfolded position is released, the blocking member 52 slides from the locking surface 311 and enters the sliding surface 315.

[0097] The sliding surface 315 may be an arc surface, an inclined surface, or a combination of the two, and it only needs to allow the blocking member 52 to slide smoothly, and is not specifically limited here.

[0098] Thus, when the lock of the deployed position is released, the blocking member 52 is operated to disengage from the locking surface 311 and can automatically slide along the sliding surface 315 as the bracket 30 rotates. When the bracket 30 rotates to the deployed position, the blocking member 52 can disengage from the sliding surface 315 and, under the action of the elastic member 53, quickly move along the locking direction and be blocked by the locking surface 311.

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

[0100] Specifically, the rod body 11 includes a main body portion 111 and a telescopic portion 115 connected to each other. The main body portion 111 has a telescopic cavity 1111, and the telescopic cavity 1111 extends along the height direction of the fan 100. The telescopic portion 115 is connected to the main body portion 111, and is configured to be able to telescope relative to the main body portion 111 through the telescopic cavity 1111. The rotating seat 131 serves as a part of the shaking mechanism 13 for realizing the shaking of the fan 100. In addition, the shaking mechanism 13 also includes a shaking assembly portion 113, which is located on the peripheral side of the main body portion 111 and has a mounting cavity 1133. The rotating seat 131 is rotatably arranged in the mounting cavity 1133 around the height direction of the fan 100.

[0101] Specifically, the locking mechanism 50 is also assembled to the rotating seat 131 through its housing 55. A support column 1311 is formed on the rotating seat 131, and the housing 55 has a matching column 554 that matches the support group.

[0102] In this way, the fan 100 can realize the shaking function through the rotating seat 131, and because the shaking assembly part 113 is located on the peripheral side of the main body 111, the space occupied by the shaking mechanism 13 in the height direction of the fan 100 is reduced, and the shaking mechanism 13 and the main body 111 can be arranged radially. The space in the height direction of the fan 100 can be more fully used for the main body 111 to extend and retract.

[0103] Please also read Fig.21 In some embodiments, the oscillating assembly portion 113 includes a mounting seat 1131, the mounting seat 1131 has a rotating column 11311 extending along the height direction of the fan 100, the rotating seat 131 has a rotating hole 1313 matched with the rotating column 11311, and the rotating seat 131 is sleeved on the rotating column 11311 through the rotating hole 1313. It can be understood that the rotating seat 131 is located on the mounting seat 1131 and can rotate with the rotating column 11311 as the rotating axis.

[0104] In this way, the rotating seat 131 can realize stable rotation through the rotating column 11311 , thereby improving the stability of the shaking of the fan 100 .

[0105] Furthermore, one of the cavity walls of the rotating column 11311 and the rotating hole 1313 is formed with a slot 11313 , and the other is formed with a buckle 1315 that cooperates with the slot 11313 . The slot 11313 and the buckle 1315 are engaged with each other to form a limit in the height direction of the fan 100 .

[0106] Specifically, the rotating column 11311 may be formed with a slot 11313 around the axial structure, and the cavity wall of the rotating hole 1313 may be formed with a buckle 1315. It can be understood that during installation, the rotating seat 131 may 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 inserted into the slot 11313 of the mounting seat 1131.

[0107] In this way, after the rotating seat 131 is installed, the cooperation between the buckle 1315 and the slot 11313 can reduce the probability of it being separated from the mounting seat 1131, which helps to improve the assembly stability of the fan 100.

[0108] Please also read Fig. 22 In some embodiments, the oscillating mechanism 13 further includes an oscillating driving member 133 , which is disposed in the mounting cavity 1133 and is transmission-connected to the rotating seat 131 .

[0109] Specifically, the oscillating assembly part 113 further includes a shell connected to the main body part 111 , and a mounting cavity 1133 is formed in the shell. The mounting cavity 1133 also has an assembly column 1135 , and the mounting seat 1131 is mounted on the assembly column 1135 .

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

[0111] Furthermore, the oscillating drive member 133 includes a driver 1331 and a driving gear 1333 . The driving gear 1333 cooperates with the output shaft of the driver 1331 . The rotating seat 131 has a matching tooth 1317 meshing with the driving gear 1333 .

[0112] Specifically, the rotating seat 131 is constructed around the height direction of the fan 100 to form a mating tooth 1317, and the driving shaft of the driver 1331 is arranged along the height direction of the fan 100. Correspondingly, the axial direction of the driving gear 1333 is also arranged along the height direction of the fan 100 and is engaged with the output shaft of the driver 1331 to prevent rotation and mesh with the mating tooth 1317.

[0113] Thus, the driver 1331 can drive the rotating seat 131 to rotate through the meshing of the driving gear 1333 and the matching teeth 1317. According to actual needs, the desired shaking speed can be obtained by reasonably reducing the speed of the driver 1331.

[0114] Specifically, the driver 1331 may be, but is not limited to, a motor. The driver 1331 may be connected to the mounting seat 1131 , and the mounting seat 1131 has a limiting column 1137 for limiting the driving gear 1333 .

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

[0116] The fan 100 further includes a damping sheet 71 , which is disposed between the first rotational mating surface 317 and the second rotational mating surface 1319 and can contact the first rotational mating surface 317 and the second rotational mating surface 1319 at the same time.

[0117] It can be understood that the damping sheet 71 can provide a damping force for the relative rotation between the first rotational mating surface 317 and the second rotational mating surface 1319, that is, provide a damping force for the flipping of the bracket 30 relative to the fuselage rod 10. The damping sheet 71 can provide either linear damping adjustment or instantaneous damping adjustment, which is not specifically limited here.

[0118] In this way, the damping sheet 71 can provide a damping force for the folding of the head 20 of the fan 100, thereby reducing the probability of damage due to over-rapid folding.

[0119] Specifically, the first rotating mating surface 317 and / or the second rotating mating surface 1319 have a mounting groove 319, and the damping sheet 71 is mounted in the mounting groove 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 portion 31 and the rotating seat 131, and is fixed by a nut 73. The shaft screw 72 also serves as the rotating shaft of the two.

[0120] For ease of understanding, the assembly process of the above-mentioned fan 100 is briefly described below: 1. First, the head 20 and the bracket 30 are rotatably connected together by means of screws or buckles 1315; 2. Assemble the shell 55 of the locking mechanism 50 with the rotating seat 131: insert the support column 1311 on the rotating seat 131 into the matching column 554 of the shell 55 (interference fitting), so that the shell 55 is embedded in the rotating seat 131; 3. Assemble the bracket 30 with the rotating seat 131: align the screw hole of the bracket 30 with the screw hole of the rotating seat 131, and then use the shaft screw 72 to pass through the screw hole on the bracket 30 and the screw hole on 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 shell 55: Put the spring as the elastic member 53 onto the shell 5 5, and then insert the button 57 into the pressing channel 551, with appropriate interference fit, so that the socket 572 of the button 57 is aligned with the movable hole 553 of the shell 55. At this time, the button 57 is embedded in the shell 55, and then the blocking member 52 is horizontally inserted into the socket 572 of the button 57 (there is interference fit between the blocking member 52 and the socket 572) and the blocking member 52 is located in the movable hole 553 of the shell 55, and the blocking member 52 passes through the shell 55; 5. The rotating seat 131 is connected to the rod body 11: the output shaft of the driver 1331 is aligned with the gear hole of the driving gear 1333 and inserted, so that the driver 1331 and the driving gear 1333 are interference fitted together, then, the screw hole of the driver 1331 is aligned with the screw column at the lower end of the mounting seat 1131, and the driver 1331 is fixed to the mounting seat 1131 with screws. After the driver 1331 is connected to the mounting seat 1131, it is placed in the mounting cavity 1133 of the rod body 11. At this time, align the screw hole of the mounting seat 1131 with the screw column in the mounting cavity 1133, and then fix the mounting seat 1131 with screws. After the mounting seat 1131 is fixed, the rotating hole 1313 of the rotating seat 131 cooperates with the rotating column 11311 of the mounting seat 1131, so that the card slot 11313 on the rotating column 11311 is buckled and connected with the buckle 1315 of the rotating seat 131, and at the same time, the matching teeth 1317 on the outer periphery of the lower end of the rotating seat 131 are kept aligned and meshed with the driving gear 1333. When the whole machine is running, the driver 1331 drives the driven part of the rotating seat 131 through the driving gear 1333; 6. Finally, the two ends of the telescopic part 115 are screwed to the main body 111 and the chassis 90 respectively.

[0121] When the button 57 is pressed, the blocking member 52 will be separated from the locking surface 311 of the bracket 30. At this time, the bracket 30 can be moved. When the bracket 30 is rotated, the blocking member 52 will move on the sliding surface 315 in the bracket 30. The bracket 30 and the head 20 are flipped forward to the front of the fuselage rod 10 until the locking surface 311 of the retaining rib 313 is against the block 51, and finally the head 20 is hung in front of the fuselage rod 10. At the same time, there is a gap (not less than 10mm) between the rear mesh grille corresponding to the air inlet 23 of the head 20 and the fuselage rod 10, which can achieve a normal blowing effect. Furthermore, the height of the fuselage is lowered by telescoping the fuselage rod 10 to adapt to the tabletop placement of the blower.

[0122] When the user wants to unfold the fan 100, the user then stretches the telescopic portion 115 downward to the bottom, and finally turns the bracket 30 over until the blocking member 52 is separated from the sliding surface 315 of the bracket 30. At this time, under the action of the spring, the blocking member 52 and the button 57 are ejected outward, and the blocking member 52 contacts the locking surface 311 of the bracket 30, thereby limiting the movement of the bracket 30 and completing the unfolding of the entire fan 100.

[0123] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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 above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
