Description

Technical Field

[0001] This invention belongs to the field of smart home technology, and specifically relates to a tower fan. Background Technology

[0002] Tower fans are smaller than traditional fans, easier to use, and deliver a gentler airflow, making them widely used in homes. However, existing tower fans generally consist of a single fan body and a base. The fan body has a narrow airflow angle and cannot provide omnidirectional airflow, thus failing to meet the needs of modern households.

[0003] To address these issues, the industry has proposed equipping tower fans with multiple fan bodies connected sequentially at different angles, allowing for omnidirectional airflow. However, the fixed connections between the fan bodies, along with the fixed connection to the base, make disassembly, cleaning, and storage inconvenient.

[0004] To address the issue of inconvenient disassembly, the industry has proposed modularizing the fan units, allowing them to be assembled for easy disassembly, cleaning, and storage. However, with modularization, each fan unit has an independent rotating shaft, driving the impeller to rotate and deliver air. The tower fan's motor output shaft is indirectly connected to the rotating shafts of each fan unit. When receiving the motor's output torque, the rotating shafts of each fan unit are prone to deviating from the central axis of the output shaft. This prevents the rotating shafts from effectively receiving the motor's torque, making each fan unit susceptible to malfunction during operation and affecting the tower fan's usability. Summary of the Invention

[0005] The purpose of this invention is to solve at least one of the above-mentioned problems by providing a tower fan.

[0006] To meet the various objectives of this invention, the following technical solutions are adopted:

[0007] To achieve one objective of this invention, a tower fan is provided, comprising a coaxially arranged base and at least two fan body assemblies. Adjacent fan body assemblies are connected by a docking assembly, wherein the docking assembly includes two docking mechanisms, namely a first docking mechanism disposed on a first fan body assembly and a second docking mechanism disposed on a second fan body assembly. The first docking mechanism is connected to the drive shaft of the first fan body assembly, and the second docking mechanism is connected to the drive shaft of the second fan body assembly. The first docking mechanism and the second docking mechanism are linked together to transmit torque to each other.

[0008] Furthermore, both the first docking mechanism and the second docking mechanism include a straightening component. The drive shaft passes through a rotating hole provided by the straightening component. The straightening component is made of a flexible material and is also provided with an annular adjustment groove surrounding the rotating hole.

[0009] Furthermore, the outer wall of the corrective component is provided with an annular groove, which is used to engage with external components.

[0010] Specifically, the rotating hole is also provided with a bearing groove, the bearing groove is provided with an oil-impregnated bearing, and the transmission shaft also passes through the bearing hole of the oil-impregnated bearing.

[0011] Furthermore, the first docking mechanism includes a first docking member, and the drive shaft on the first fan body assembly is inserted into the connection hole of the first docking member. The second docking mechanism includes a second docking member, and the drive shaft on the second fan body assembly is inserted into the connection hole of the second docking member. The first docking member and the second docking member are connected to each other.

[0012] Furthermore, the first docking member is provided with a plurality of snap-fit ​​pieces arranged in a clockwise direction, and the second docking member is provided with a plurality of snap-fit ​​pieces arranged in a counterclockwise direction, and the plurality of snap-fit ​​pieces on the first docking member and the plurality of snap-fit ​​pieces on the second docking member snap-fit ​​each other.

[0013] Furthermore, a self-locking mechanism is provided between the two adjacent fan body components, which is used to lock the two adjacent fan body components so that the two fan body components are stably connected.

[0014] Furthermore, the self-locking mechanism includes an interface seat, a locking pin, and a collar. The interface seat has an interface groove on one side and an annular wall protruding from the other side. The locking pin passes through the annular wall and enters the interface groove. The collar is clamped around the outer periphery of the annular wall to press down the locking pin. The interface seat of the self-locking mechanism is fixed in the interface channel provided by the first fan body assembly, and the insertion wall of the second fan body assembly is inserted into the interface groove of the interface seat.

[0015] Specifically, the locking pin includes a pin body and a cap body located at one end of the pin body. The cap body has an external protrusion on its side. The maximum outer diameter of the cap body is interference-fitted with a through hole provided on the annular cavity. The locking pin is disposed through the through hole.

[0016] Specifically, the inner wall of the collar forms a step along the circumference, and the step includes an unlocking surface and a locking surface, with a smooth transition between the unlocking surface and the locking surface.

[0017] Specifically, the interface seat is provided with a through second interface slot, and the drive shaft of the second fan body assembly is connected to the second interface slot of the interface seat, passing through the second interface slot and linked with the drive shaft of the first fan body assembly.

[0018] Compared with existing technologies, the present invention has many advantages, including but not limited to:

[0019] On the one hand, the two adjacent fan body components of the tower fan of the present invention are connected by a docking component. The two docking mechanisms of the docking component are respectively disposed on the two fan body components. The docking parts of the two docking mechanisms are connected to each other, so that the two fan body components transmit torque. When the drive shaft of the fan body component jumps due to vibration during operation, the offset caused by the jump can be corrected, so that the drive shaft returns to its original position, so as to facilitate good transmission and make the tower fan operate well and deliver air to the outside.

[0020] On the other hand, the tower fan of the present invention facilitates the modularization of each fan body component by setting a docking component, which makes it easier to assemble and disassemble the tower fan and to transport the tower fan.

[0021] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and will become apparent from the description or may be learned by practice of the invention. Attached Figure Description

[0039] The present invention provides a tower fan with multiple fan body components, which are connected to each other by a docking component, so as to modularize the multiple fan body components of the tower fan. The docking component can reduce problems such as center misalignment and operation jump caused by the drive shafts of the two fan body components that are connected to each other, so that the tower fan can operate smoothly.

[0040] In a typical embodiment of the present invention, combined with Figure 1 The tower fan 100 includes a base 110 and a fan body 120. The fan body 120 is disposed on the base 110, and the base 110 and the fan body 120 are arranged along a first axis. The fan body 120 includes a plurality of fan body components 130, which are connected to each other along the first axis to form the fan body 120. Preferably, the fan body 120 is composed of at least two fan body components 130.

[0041] The base 110 includes a chassis 111 and a pedestal 112 disposed on the chassis 111, and the fan body 120 is disposed on the pedestal 112. Figure 2 and Figure 3 The base 112 includes a housing 1121, in which a receiving groove 1122 is formed, and a motor 113 is provided in the receiving groove 1122. The motor 113 is used to drive the fan body 120 to deliver air to the outside.

[0042] The fan body 120 comprises multiple fan body components 130 that are interconnected along a first axis, with adjacent fan body components 130 connected by a docking component 140. Each fan body component 130 includes a housing 131 and a fan wheel 132. An interface channel 133 is formed in the housing 131, and the fan wheel 132 is disposed within the interface channel 133. An air outlet 134 is provided on the side wall of the housing 131. The fan wheel 132 rotates to generate air, which is then emitted externally through the air outlet 134. A drive shaft 135 is provided in the fan wheel 132. The drive shaft 135 is directly or indirectly connected to the output shaft of the motor 113 to receive the torque output by the motor 113 and drive the fan wheel 132 to rotate via the drive shaft 135.

[0043] After clarifying the basic structure of the relevant detachable tower fan, the following will combine... Figure 4 and Figure 5 The docking component 140 of the present invention will be described. Two adjacent fan body components 130 are connected by the docking component 140. The docking component 140 includes two docking mechanisms 141, which are respectively disposed on the two fan body components 130. The two docking mechanisms 141 are connected to connect the two fan body components 130.

[0044] Specifically, the docking mechanism 141 is disposed within the interface channel 133 of the housing 131 of the fan assembly 130, and is disposed at the top or bottom of the interface channel 133. Figure 5 and Figure 6 The docking mechanism 141 includes a straightening element 142 and a docking element 143, which are arranged along the first axis. Figure 7 The corrective element 142 has a through rotating hole 1421, which is combined with Figure 8 The docking member 143 is provided with a connecting hole 1431, and the central axis of the rotating hole 1421 and the connecting hole 1431 coincides with the first axis. Figure 5 The drive shaft 135 of the fan assembly 130 passes through the rotating hole 1421 along the first axis and enters the connecting hole 1431.

[0045] Combination Figure 7 and Figure 9 The corrective element 142 is made of flexible material and is also provided with an annular adjustment groove 1422. The annular adjustment groove 1422 is located outside the rotating hole 1421 and is spaced apart from the rotating hole 1421. When the drive shaft 135 passing through the rotating hole 1421 is vibrated and shifts to one side of the corrective element 142, the drive shaft 135 compresses the annular adjustment groove 1422 along its shift direction. Because the annular adjustment groove 1422 is made of flexible material and has a groove-shaped structure, it has a reaction force to push the drive shaft 135 back to its original position, so that the drive shaft 135 can receive the torque output by the motor 113 and drive the impeller 132 to rotate smoothly.

[0046] Combination Figure 6 and Figure 9 The rotating hole 1421 is further provided with a bearing groove 1423, and an oil-impregnated bearing 144 is provided in the bearing groove 1423. The drive shaft 135 passes through the rotating hole 1421 and also through the bearing hole (not shown) of the oil-impregnated bearing 144. The oil-impregnated bearing 144 allows the drive shaft 135 to rotate smoothly and separates the drive shaft 135 from the rotating hole 1421, avoiding friction between the drive shaft 135 and the rotating hole 1421 and damage to the straightening member 142.

[0047] See Figure 9The bearing groove 1423 includes two openings 1425 and a groove 1426 disposed between the two openings 1425. The cross-sectional area of ​​the groove 1426 is larger than the cross-sectional area of ​​the openings 1425. The oil-impregnated bearing 144 is disposed in the groove 1426, making it difficult for the oil-impregnated bearing 144 to come out of the bearing groove 1423, thus maintaining structural stability and facilitating stable cooperation between the oil-impregnated bearing 1423 and the transmission shaft 135 for transmission.

[0048] Furthermore, the width of the cross-section of the opening 1425 is smaller than the width of the cross-section of the groove 1426, and the width of the cross-section of the oil-impregnated bearing 144 is larger than the width of the cross-section of the opening 1425. In this embodiment, the minimum width of the cross-section of the oil-impregnated bearing 144 is also greater than the width of the cross-section of the opening 1425, so that the oil-impregnated bearing 144 will not come out of the bearing groove 1423.

[0049] The drive shaft 135 extends into the connecting hole 1431 of the docking member 143, and the drive shaft 135 is fixedly connected to the connecting hole 1431, so that when the drive shaft 135 rotates, it drives the docking member 143 to rotate. Preferably, the connecting hole 1431 is a through hole or a blind hole.

[0050] In one embodiment, combined Figure 6 and Figure 9 The section of the drive shaft 135 inserted into the connecting hole 1431 (referred to as the connecting section 1351) is provided with external threads, and the connecting hole 1431 is provided with internal threads, so that the connecting section 1351 and the connecting hole 1431 are threadedly connected. Alternatively, the cross-section of the connecting section 1351 is not circular, and the cross-sectional shape of the connecting hole 1431 corresponds to the cross-sectional shape of the connecting section 1351. Preferably, the cross-section of the connecting section 1351 is rectangular.

[0051] Combination Figure 6 , Figure 8 and Figure 9 The docking member 143 is further provided with a connecting portion 1432, which is located away from the straightening member 142 and does not face the straightening member 142. The connecting portion 1432 is provided with multiple snap-fit ​​pieces 1433, which are arranged sequentially in a clockwise or counterclockwise direction. The connecting portion 1432 is used to snap into the connecting portion 1432 of the docking member 143 of the docking mechanism 141. When the docking member 143 is driven to rotate by the drive shaft 135, the docking member 143 can drive the docking member 143 of the adjacent docking mechanism 141 to rotate, thereby driving the drive shaft 135 of the adjacent fan assembly 130, which is inserted on the docking member 143, to rotate, and further driving the impeller 132 of the adjacent fan assembly 130 to rotate.

[0052] After clarifying the docking mechanisms related to the tower fan, Figure 1 Taking the tower fan shown as an example, this section describes the specific location and arrangement of the docking mechanism within the tower fan. Specifically, it combines... Figure 1 Two adjacent sector components are referred to as the first sector component 150 and the second sector component 160. The docking mechanism set on the first sector component 150 is referred to as the first docking mechanism 151, and the docking mechanism set on the second sector component 160 is referred to as the second docking mechanism 161. The first docking mechanism 151 and the second docking mechanism 161 are connected to form a docking component 140.

[0053] Combination Figure 5 , Figure 6 and Figure 9 The first fan assembly 150 has a first drive shaft 153 on its first impeller 152. The first drive shaft 153 passes through the rotation hole 1541 on the first straightening member 154 of the first docking mechanism 151 and the bearing hole on the first oil-impregnated bearing 156 in sequence, and extends into the connection hole 1551 of the first docking member 155. The second fan assembly 160 has a second drive shaft 163 on its second impeller 162. The second drive shaft 163 passes through the rotation hole 1641 on the second straightening member 164 of the second docking mechanism 161 and the bearing hole on the second oil-impregnated bearing 166 in sequence, and extends into the connection hole 1651 of the second docking member 165.

[0054] Combination Figure 6 and Figure 8 The first docking member 155 has multiple snap-fit ​​pieces 1553 arranged in a clockwise direction, and the second docking member 165 has multiple snap-fit ​​pieces 1653 arranged in a counterclockwise direction. The connecting portion of the first docking member 155 and the connecting portion of the second docking member 165 are arranged opposite each other, and the multiple snap-fit ​​pieces 1553 of the first docking member 155 engage with the multiple snap-fit ​​pieces 1653 of the second docking member 165, so that the first docking member 155 and the second docking member 165 are linked together. That is to say, the first docking member 155 can drive the second docking member 165 to rotate, or the second docking member 165 can drive the first docking member 155 to rotate. Preferably, the outer side of the snap-fit ​​pieces 1553 of the first docking member 155 is provided with a connecting wall 1554, which is sequentially connected to the multiple snap-fit ​​pieces 1553 of the first docking member 155 to maintain the structural stability of the first docking member 155 and facilitate stable engagement with the second docking member 165.

[0055] In a typical embodiment of the present invention, combined with Figure 1 and Figure 3The first fan assembly 150 is closer to the base 110 than the second fan assembly 160. After the first drive shaft 153 of the first fan assembly 150 receives the torque output by the motor 113, the first drive shaft 153 outputs the torque to the second drive shaft 163 of the second fan assembly 160 through the docking assembly 140, so that the second drive shaft 163 rotates.

[0056] Specifically, in combination Figure 9 Since the first drive shaft 153 is inserted into the connection hole 1551 of the first docking member 155, when the first drive shaft 153 rotates, in addition to driving the first impeller 152 of the first fan body assembly 150 to rotate, the first drive shaft 153 also drives the first docking member 155 to rotate; since the first docking member 155 is engaged with the second docking member 165, the first docking member 155 drives the second docking member 165 to rotate; since the second drive shaft 163 of the second fan body assembly 160 is inserted into the connection hole 1651 of the second docking member 165, the second docking member 165 drives the second drive shaft 163 to rotate, and the second drive shaft 163 drives the second impeller 162 of the second fan body assembly 160 to rotate.

[0057] Because the first drive shaft 153 and the second drive shaft 163 are not directly connected, but are indirectly connected through the first mating part 155 and the second mating part 165, when the first drive shaft 153 and the second drive shaft 163 transmit torque, they may deviate from the first axis due to vibration, which makes it impossible for the first drive shaft 153 and the second drive shaft 163 to transmit torque well.

[0058] Specifically, during the docking of the fan assembly 130, the drive shaft 135 may deviate from the first axis. However, since the drive shaft 135 is inserted into the corrector 142, the drive shaft 135 will apply torque in its deviation direction to compress the annular adjustment groove 1422 of the corrector 142, causing the annular adjustment groove 1422 to deform. Because the corrector 142 is made of flexible material, after the annular adjustment groove 1422 is deformed by the drive shaft 135, it will generate a reaction force opposite to the deviation direction of the drive shaft 135, thus springing the drive shaft 135 back to the first axis, allowing the drive shaft 135 to reset and ensuring good torque transmission. Furthermore, the corrector 142 can also counteract the vibration and noise caused by the misalignment of the drive shaft 135.

[0059] In the multiple fan body components 130 of the fan body 120 of the tower fan 100, the docking component 140 is provided between each two adjacent fan body components 130 so that the multiple fan body components 130 are docked to form the fan body 120.

[0060] Having clarified the assembly method and related principles of the detachable tower fan, the following describes in detail the self-locking mechanism 170 in this application, which is used to secure adjacent fan body components 130 and prevent them from easily separating. In a typical embodiment of the invention, combined with... Figure 4 and Figure 9 The fan assembly 130 also includes a self-locking mechanism 170, which is used to lock two adjacent fan assemblies 130, allowing them to be stably connected. The first fan assembly 150 and the second fan assembly 160 are locked together by the self-locking mechanism 170, which is located at the top of the interface channel 133 of the housing 131 of the first fan assembly 150.

[0061] Combination Figure 10 The self-locking mechanism 170 includes an interface seat 171, a locking pin 172, and a collar 173. The interface seat 171 is disposed on the top of the interface channel 133 and is fixed to the outer shell 131 of the first fan assembly 150. The first surface 1718 of the interface seat 171 facing the second fan assembly 160 is recessed towards the base 110 to form an interface groove 1711.

[0062] Combination Figure 11 The interface groove 1711 is divided into a first interface groove 1712 and a second interface groove 1713. The central axis of the second interface groove 1713 coincides with the first axis, and the second interface groove 1713 is located at the geometric center of the first surface 1718. The first interface groove 1712 is an annular groove located outside the second interface groove 1713, and the first interface groove 1712 surrounds the second interface groove 1713.

[0063] Combination Figure 9 and Figure 12 The bottom of the interface channel 133 of the second fan body assembly 160 is provided with a fixing seat 174, which is fixed to the outer shell 131 of the second fan body assembly 160. The fixing seat 174 is provided with an annular insertion wall 1741, which is inserted into the first interface groove 1712, so that the interface seat 171 and the fixing seat 174 are assembled.

[0064] The fixing seat 174 is also provided with a fixing groove 1742. The central axis of the fixing groove 1742 coincides with the first axis, and the fixing groove 1742 is opposite to the second interface groove 1713 of the interface seat 171. The fixing groove 1742 and the second interface groove 1713 are configured to form a receiving cavity 175. The receiving cavity 175 is used to receive the docking component 140 that allows the first fan body component 150 and the second fan body component 160 to align.

[0065] Specifically, in combination Figure 7 , Figure 12 and Figure 9 The outer side wall of the corrective member 142 is provided with an annular groove 1424. The bottom of the first interface groove 1712 is hollowed out to form a first retaining wall 1714 corresponding to the annular groove 1424. The bottom of the fixing groove 1742 of the fixing seat 174 is hollowed out to form a second retaining wall 1743 corresponding to the annular groove 1424.

[0066] The annular groove 1424 of the first straightening member 154 of the first docking mechanism 151 of the docking assembly 140 engages with the first retaining wall 1714 on the second interface groove 1713 of the interface seat 171. The annular groove 1424 of the second straightening member 164 of the second docking mechanism 161 engages with the second retaining wall 1743 of the fixing groove 1742 of the fixing seat 174, so that the fixing seat 174 and the interface seat 171 are stably connected, maintaining the structural stability of the receiving cavity 175, so that the receiving cavity 175 can stably receive the docking assembly 140, so that the docking assembly 140 can stably connect the first sector assembly 150 and the second sector assembly 160.

[0067] Furthermore, since the interface seat 171 is fixed to the outer shell 131 of the first fan body assembly 150, and the fixing seat 174 is fixed to the outer shell 131 of the second fan body assembly 160, the insertion wall 1741 of the fixing seat 174 is inserted into the first interface groove 1712 of the interface seat 171, so that the interface seat 171 and the fixing seat 174 are assembled.

[0068] Combination Figure 10 The collar 173 is disposed on the outer side of the interface seat 171 and clamps the interface seat 171. The locking pin 172 is disposed between the collar 173 and the interface seat 171. The side wall of the interface seat 171 protrudes to form an annular wall 1715. The interface seat 171 has a through hole 1716 corresponding to the position of the locking pin 172. The through hole 1716 extends from the annular wall 1715 into the first interface groove 1712. The locking pin 172 is inserted into the first interface groove 1712 through the through hole 1716 to abut against the insertion wall 1741 of the fixing seat 174 inserted into the first interface groove 1712, so that the fixing seat 174 and the interface seat 171 are fixedly connected. The fixing seat 174 and the interface seat 171 can be separated by releasing the locking pin 172, so that the two adjacent fan body assemblies 130 can be disassembled.

[0069] The inner wall 1731 of the collar 173 is provided with a step 1732, which is arranged along the axial direction of the collar 173. The step 1732 includes an unlocking surface 1733 and a locking surface 1734. The locking surface 1734 is closer to the annular wall 1715 of the interface seat 171 than the unlocking surface 1733. The unlocking surface 1733 and the locking surface 1734 are connected and smoothly transitioned.

[0070] Combination Figure 13 The locking pin 172 includes a pin body 1721 and a cap 1722 disposed at one end of the pin body 1721. The other end of the pin body 1721 (referred to as the locking end 1723) is used to abut against the insertion wall 1741 disposed in the first interface groove 1712. Figure 9 The end face of the cap 1722 abuts against the step 1732. When the cap 1722 abuts against the locking surface 1734 of the step 1732, the locking end 1723 of the pin 1721 abuts against the insertion wall 1741, thereby locking the fixing seat 174 by abutting against the insertion wall 1741, so that the fixing seat 174 is locked with the interface seat 171, that is, the first fan assembly 150 and the second fan assembly 160 are locked. Rotating the collar 173 separates the locking surface 1734 of the step 1732 from the cap 1722, while the unlocking surface 1733 of the step 1732 abuts against the cap 1722. When the cap 1722 abuts against the unlocking surface 1733 of the step 1732, the locking end 1723 of the pin 1721 no longer abuts against the insertion wall 1741, causing the fixing seat 174 to separate from the interface seat 171. That is, the first fan assembly 150 and the second fan assembly 160 are separated, so as to facilitate the disassembly of the first fan assembly 150 and the second fan assembly 160.

[0071] Combination Figure 13 The cap body 1722 also has a recessed groove 1724 on its side. An external protrusion 1725 protrudes from the groove wall of the recessed groove 1724 and is suspended within the groove, protruding from the cap body 1722. Because of the external protrusion 1725, the maximum outer diameter of the cap body 1722 is larger than the inner diameter of the through hole 1716, resulting in an interference fit between the cap body 1722 and the through hole 1716, thus preventing the cap body 1722 from easily falling out of the through hole 1716.

[0072] Combination Figure 9 and Figure 11The through hole 1716 is also provided with a notch 1717, and the outer protrusion 1725 is provided with a protrusion 1726. The protrusion 1726 and the notch 1717 can be elastically engaged. When the locking pin 172 does not abut against the insertion wall 1741, that is, when unlocked, the protrusion 1726 of the outer protrusion 1725 enters the notch 1717, so that the cap 1722 and the through hole 1716 are in clearance fit, so as to pull the locking pin 172, thereby unlocking the fixing seat 174 from the interface seat 171.

[0073] When it is necessary to lock the fixing seat 174 and the interface seat 171, the locking pin 172 is pushed towards the direction of the insertion wall 1741, and the locking end 1723 abuts against the insertion wall 1741, so that the cap 1722 drives the protrusion 1726 away from the notch 1717 and into the through hole 1716, so that the cap 1722 and the through hole 1716 are interference fit, and the locking pin 172 is not easy to loosen, so that the locking pin 172 can stably abut against the insertion wall 1741, so that the fixing seat 174 and the interface seat 171 are fixed together, and the docking assembly 140 provided in the receiving cavity 175 formed by the fixing seat 174 and the interface seat 171 can also be fixed, so that the first fan body assembly 150 and the second fan body assembly 160 are stably docked.

[0074] In one embodiment, combined Figure 9 A return spring 176 is also fitted onto the pin body 1721 of the locking pin 172. When the pin body 1721 moves away from the insertion wall 1741, the return spring 176 is compressed, giving the return spring 176 a spring force toward the insertion wall 1741, reducing the difficulty of pushing the locking end 1723 of the locking pin 172 toward the insertion wall 1741. Furthermore, when the locking pin 172 abuts against the insertion wall 1741, the return spring 176 also provides a spring force, ensuring that the locking pin 172 stably abuts against the insertion wall 1741, so that the first sector assembly 150 and the second sector assembly 160 can lock each other.

[0075] In one embodiment, the self-locking mechanism 170 is provided with a plurality of locking pins 172, which stably lock the fixing seat 174, thereby enabling the first fan body assembly 150 and the second fan body assembly 160 to be stably connected.

[0076] In one embodiment, combined Figure 10 The outer wall of the collar 173 is provided with a force-applying protrusion 1735. By applying force to the force-applying protrusion 1735, the collar 173 is pushed to rotate, so that the step 1732 set on it can rotate, thereby realizing the locking or unlocking between the first fan body assembly 150 and the second fan body assembly 160.

[0077] In a further embodiment, combined with Figure 1 The outer shell 131 of the first fan assembly 150 forms a sliding groove 1311 corresponding to the force-applying protrusion 1735, and the sliding groove 1311 is a through groove. Combined with... Figure 10 The force-applying protrusion 1735 is provided with a force-applying groove 1736, and a sliding member 177 is provided corresponding to the force-applying groove 1736. The sliding member 177 is fixedly connected to the force-applying groove 1736. By applying a force to the sliding member 177, the force-applying protrusion 1735 is driven to move.

[0078] In one embodiment, one of the two adjacent fan body assemblies 130 is provided with a self-locking mechanism 170 to lock the two adjacent fan body assemblies 130.

[0079] In one embodiment, the docking component 140 and the self-locking mechanism 170 are also provided between the base 110 and the connected fan assembly 130. Specifically, a second docking mechanism 161 of the docking component 140 is provided within the housing 1121 of the base 110, and the output shaft of the motor 113 is connected to a connection hole 1651 on the second docking member 165 of the second docking mechanism 161. A first docking mechanism 151 of the docking component 140 is provided within the interface channel 133 of the housing 131 of the fan assembly 130.

[0080] The self-locking mechanism 170 is provided on the fan assembly 130. The self-locking structure 170 can be provided between the base 110 and the connected fan assembly 130 so that the base 110 and the connected fan assembly 130 are stably connected and the base 110 and the connected fan assembly 130 are easy to assemble and disassemble.

[0081] The specific configuration of the docking component 140 and the self-locking mechanism 170 between the base 110 and the connected fan assembly 130 can be found in the above description of the installation method of the docking component 140 and the self-locking mechanism 170 between the first fan assembly 150 and the second fan assembly 160. For the sake of brevity, it will not be described again here.

[0082] In one embodiment, the docking mechanism 141 and the self-locking mechanism 170 can be provided at both ends of the fan assembly 130.

[0083] In summary, the base and multiple fan body components of the tower fan of the present invention are modularized to facilitate assembly and disassembly. Furthermore, the fan body components are connected to each other through docking components, which enables good transmission between the fan body components and reduces the runout of the transmission shaft of the fan body components during operation, so as to ensure the smooth operation of the tower fan.
