For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] Reference below Figure 1-Figure 18 A tower fan according to an embodiment of the present invention is described.

[0051] Reference Figure 1 , Figure 2 and Figure 3 The tower fan 100 according to the embodiment of the utility model comprises: a first part 200 and a second part 300, wherein the first part 200 is mainly a component for completing airflow discharge, and the second part 300 is mainly a component for providing power to the first part 200. The first part 200 and the second part 300 are detachably connected so that the first part 200 has an assembled state and a separated state.

[0052] Reference Figure 1 , Figure 2 and Fig.10Specifically, the first part 200 includes a housing 1 and a wind wheel 2. The housing 1 is provided with an air outlet 11. The wind wheel 2 is arranged in the housing 1 to guide air to the air outlet 11. The second part 300 includes a base 3 and a motor 4. The motor 4 is arranged on the base 3. The motor 4 and the wind wheel 2 can be detachably matched to drive the wind wheel 2 to rotate. In the assembled state, the housing 1 is connected to the base 3 to ensure the stability of the first part 200. The wind wheel 2 is connected to the motor 4 so that the motor 4 can drive the wind wheel 2 to rotate to achieve fanning. In the separated state, the housing 1 is separated from the base 3, and the wind wheel 2 is separated from the motor 4.

[0053] Because the motor 4 is disposed in the second part 300 and there are no electrical components in the first part 200, there is no risk of short circuit when cleaning the first part 200, which improves the convenience of cleaning the first part 200. For example, when the first part 200 needs to be cleaned, the first part 200 can be removed from the second part 300 and directly rinsed under the faucet.

[0054] Reference Figure 5 and Fig.10 The second part 300 further includes: a circuit module and a switch module 7, wherein the circuit module is respectively connected to the power module and the motor 4 to deliver current to the motor 4, and the switch module 7 is connected to the circuit module to control the on and off of the circuit module. It should be noted that the power module can be an external power source or a battery module disposed inside the tower fan 100, as long as it can deliver current to the motor 4.

[0055] The first part 200 is provided with a trigger member 68. In the assembled state, the trigger member 68 is suitable for triggering the switch module 7, and the circuit module is powered on. In the separated state, the trigger member 68 is separated from the switch module 7, and the circuit module is powered off.

[0056] In the separated state, the first part 200 is completely separated from the second part 300, that is, the trigger member 68 is also separated from the switch module 7, resulting in that after the first part 200 is disassembled, the circuit module is powered off, that is, the motor 4 is powered off, thereby effectively avoiding the risk caused by the rotation of the output end of the motor 4 and improving the safety of the tower fan 100.

[0057] According to the tower fan 100 of the embodiment of the utility model, the first part 200 can be separated from the second part 300 as a whole, which improves the convenience for users to clean the casing 1 and the wind wheel 2; and through the cooperation of the switch module and the trigger member, the second part is in a power-off state when in the separated state, which effectively avoids the risks brought by the rotation of the output end of the motor 4 and improves the safety of the tower fan 100.

[0058] Reference Figure 1 , Figure 2 and Fig.10In some embodiments, the housing 1 includes: a front shell 12, a rear shell 13, an upper shell 14 and a lower shell 15, the front shell 12, the rear shell 13, the upper shell 14 and the lower shell 15 define an installation space for the wind wheel 2, and the front shell 12 is provided with an air outlet 11.

[0059] The housing 1 of the first part 200 is assembled by the front housing 12 , the rear housing 13 , the upper housing 14 and the lower housing 15 , which helps to reduce the difficulty of mold opening of the housing 1 and reduce the cost.

[0060] In some embodiments, the front housing 12, the rear housing 13, the upper housing 14 and the lower housing 15 can be connected by multiple fasteners (screws or bolts), and the connection is reliable. In other embodiments, the front housing 12, the rear housing 13, the upper housing 14 and the lower housing 15 can also be combined into one body by ultrasonic technology or bonded into one body by glue, or can be detachably connected by a snap-fit ​​structure, which is also conducive to later maintenance or replacement. Other situations are also possible, as long as the front housing 12, the rear housing 13, the upper housing 14 and the lower housing 15 are connected.

[0061] Reference Figure 1 , Figure 2 and Fig.10 In some embodiments, the base 3 includes a support frame 32 and a housing 33 covering the support frame 32 , and the motor 4 is installed on the support frame 32 , that is, the motor 4 is located in the housing 33 to protect the motor 4 .

[0062] The housing 33 includes a first shell 331 and a second shell 332 disposed on the peripheral side of the support frame 32. The first shell 331 and the second shell 332 are spliced ​​into a cylindrical structure that is externally mounted on the support frame 32. The housing 33 also includes a cover 333 disposed on the top of the support frame 32 to protect the top of the support frame 32. The cover 333, the first shell 331 and the second shell 332 are combined to form the housing 33.

[0063] In the above technical solution, the housing 33 is composed of a first housing 331 , a second housing 332 and a cover 333 , which is conducive to reducing the difficulty of mold opening of the housing 33 and reducing the cost.

[0064] In some embodiments, the cover 333, the first shell 331 and the second shell 332 can be connected by multiple fasteners (screws or bolts), and the connection is reliable. In other embodiments, the cover 333, the first shell 331 and the second shell 332 can also be combined into one body by ultrasonic technology or bonded into one body by glue, or can be detachably connected by a snap-on structure, which is also conducive to later maintenance or replacement. Other situations are also possible, as long as the cover 333, the first shell 331 and the second shell 332 are connected.

[0065] Because the first part 200 and the second part 300 are detachably connected, when the housing 1 is connected to the base 3, the motor 4 is connected to the wind wheel 2, therefore, the lower shell 15 of the housing 1 and the cover 333 of the housing 33 are both provided with a first avoidance area to avoid the connection between the motor 4 and the wind wheel 2. In the embodiment of the utility model, the motor 4 and the wind wheel 2 are designed to meet the following conditions: when the housing 1 is docked with the base 3, the motor 4 and the wind wheel 2 are automatically connected by power, and when the housing 1 is separated from the base 3, the motor 4 and the wind wheel 2 are automatically disconnected.

[0066] Reference Figure 3 , Figure 4 and Fig.10 In some specific embodiments, a first clutch 21 is provided at the bottom end of the wind wheel 2, and an upwardly disposed output shaft of the motor 4 is connected to a second clutch 42. When the first part 200 is installed on the second part 300, the first clutch 21 is engaged with the second clutch 42, and the first clutch 21 and the second clutch 42 are synchronously rotated by meshing or friction. When the first part 200 is removed from the second part 300, the first clutch 21 is separated from the second clutch 42, and the wind wheel 2 is disconnected from the motor 4.

[0067] In some other embodiments, the detachable cooperation between the motor 4 and the wind wheel 2 can also be magnetically attracted, and when the first part 200 is installed on the second part 300, the wind wheel 2 and the output shaft of the motor 4 are synchronously rotated by magnetic force. The connection between the wind wheel 2 and the motor 4 can also be other ways, as long as the wind wheel 2 and the motor 4 are automatically connected when the housing 1 and the base 3 are docked, and the wind wheel 2 and the motor 4 are separated when the housing 1 and the base 3 are separated.

[0068] Reference Figure 3 , Figure 4 and Fig.10 In some embodiments, the first part 200 is plugged into the second part 300, one of the housing 1 and the base 3 is provided with a mounting boss 36 extending toward the other, and the other of the housing 1 and the base 3 is provided with a mounting groove 66 plugged into the mounting boss 36. The plug-in fit between the mounting boss 36 and the mounting groove 66 improves the stability of the connection between the housing 1 and the base 3.

[0069] The housing 1 may be provided with a mounting boss 36 and the base 3 may be provided with a mounting groove 66; or the housing 1 may be provided with a mounting groove 66 and the base 3 may be provided with a mounting boss 36. As long as the cooperation between the mounting boss 36 and the mounting groove 66 can improve the stability of the connection between the housing 1 and the base 3. In some specific embodiments, the top of the base 3 is provided with a mounting boss 36 extending upward, and the bottom of the housing 1 is provided with a mounting groove 66.

[0070] Reference Figure 5In some embodiments, the trigger member 68 is fixedly disposed on the side of the housing 1 facing the base 3. When the first part 200 and the second part 300 are docked, the mounting boss 36 and the mounting groove 66 are plugged into each other, and the trigger member 68 presses the switch module 7 to trigger the switch module 7, so that the current module is energized.

[0071] In the above technical solution, the matching mode of the trigger member 68 and the switch module 7 is simple, which reduces the cost of the tower fan 100.

[0072] In the above technical solution, when the first part 200 and the second part 300 are connected, there are many parts between the two, and there may be an assembly error between the first part 200 and the second part 300. The trigger stroke of the switch module 7 is only a few millimeters, so the trigger member 68 may not be pressed. When this happens, even if the first part 200 is installed on the second part 300, the powered-off motor 4 cannot drive the wind wheel 2 to rotate.

[0073] Reference Figure 4 , Figure 8 and Fig. 9 In order to improve the above problem, in other embodiments, the trigger member 68 is movably arranged in the first part 200. In the assembled state, the trigger member 68 can move to trigger or move away from the switch module 7. There is an angle between the plug-in direction of the first part 200 relative to the second part 300 and the movable direction of the trigger member 68.

[0074] In the embodiment of the utility model, because the trigger member 68 is movably arranged on the first part 200, even if an assembly error occurs between the first part 200 and the second part 300, the impact of the assembly error can be reduced by the movement of the trigger member 68, thereby reducing the risk that the trigger member 68 cannot press the trigger switch module 7 due to the assembly error between the first part 200 and the second part 300.

[0075] In addition, an angle is formed between the plugging direction of the first part 200 relative to the second part 300 and the moving direction of the trigger member 68, which further reduces the impact of the assembly error between the first part 200 and the second part 300 and improves the reliability of the tower fan 100.

[0076] In some specific embodiments, the plugging direction of the first part 200 relative to the second part 300 is perpendicular to the moving direction of the trigger member 68 .

[0077] Through the above technical solution, even if an assembly error occurs between the first part 200 and the second part 300, it will not affect the movement of the trigger member 68, and will not affect the movement of the trigger member 68 to trigger the switch module 7, further improving the reliability of the tower fan 100.

[0078] In some specific embodiments, referring to Figure 2 , the first part 200 and the second part 300 are arranged in the vertical direction. Figure 6 and Figure 7 The switch module 7 includes a metal spring 71 and two contact points connected to the circuit module. When the metal spring 71 contacts both contact points, the circuit module is turned on. Figure 7 , Figure 8 and Fig. 9 In the horizontal direction, the trigger member 68 is located on one side of the metal dome 71 to trigger the metal dome 71. When the trigger member 68 is away from the metal dome 71, the metal dome 71 moves one end toward the side away from the contact point under the action of its own restoring force, thereby disconnecting the switch module 7. When the trigger member 68 moves toward the metal dome 71, the metal dome 71 is pressed, so that the metal dome 71 contacts both contact points, thereby turning on the switch module 7.

[0079] In the embodiment of the utility model, when the first part 200 is installed on the second part 300, the first part 200 is docked with the second part 300 in the vertical direction, and then the trigger member 68 is moved in the horizontal direction, so that the trigger member 68 triggers the metal spring 71 in the horizontal direction, so that the switch module 7 is turned on and the motor 4 is powered. Because the trigger member 68 triggers the switch module 7 in the horizontal direction, the influence caused by the assembly error of the first part 200 and the second part 300 in the vertical direction is reduced, and the normal use of the tower fan 100 is guaranteed.

[0080] Reference Figure 3 , Figure 4 and Figure 6 In some embodiments, the second part 300 is provided with a housing 33, the switch module 7 and the circuit module are both located in the housing 33, the housing 33 is provided with a second avoidance area 361, and the trigger member 68 is arranged to extend into the second avoidance area 361 to trigger the switch module 7.

[0081] It should be noted that the switch module 7 and the circuit module are both located in the casing 33. The switch module 7 and the circuit module may be completely located in the casing 33. For example, a battery module is also provided in the casing 33, so that the circuit module can complete the electrical connection between components in the casing 33; or a part of the circuit module may extend outside the casing 33 to connect with an external power supply.

[0082] The above technical solution reduces the risk of the switch module 7 and the circuit module being accidentally touched by arranging the switch module 7 and the circuit module in the housing 33, thereby improving the safety of the tower fan 100.

[0083] Reference Figure 3 , Figure 4 and Figure 6In some specific embodiments, a mounting boss 36 is provided on the top of the housing 33, and the second avoidance area 361 includes a avoidance groove 3611 provided at the end of the mounting boss 36, and the bottom wall of the avoidance groove 3611 is provided with an avoidance opening 3612 connected to the interior of the housing 33. In the assembled state, the trigger member 68 passes through the avoidance groove 3611 and the avoidance opening 3612 to trigger the switch module 7.

[0084] The above technical solution has a simple structure and is easy to process, thereby reducing the cost of the tower fan 100.

[0085] Reference Figure 7 , Figure 8 and Fig. 9 In some embodiments, the tower fan 100 further includes a protective member 38, which is disposed on the second portion 300 to prevent liquid from flowing to the switch module 7, thereby reducing the risk of short circuit of the switch module 7 and improving the safety of the tower fan 100.

[0086] Reference Figure 3 , Figure 8 and Fig. 9 In some specific embodiments, the switch module 7 and the avoidance opening 3612 are staggered in the vertical direction to prevent external liquid from directly contacting the switch module 7 after entering the avoidance opening 3612, thereby reducing the risk of short circuit of the switch module 7.

[0087] The protection member 38 is rotatably disposed between the switch module 7 and the trigger member 68 so as to be driven to rotate by the trigger member 68 or the switch module 7 . The trigger member 68 is suitable for triggering the switch module 7 through the protection member 38 .

[0088] In the above technical solution, in the assembled state, the trigger member 68 passes through the avoidance opening 3612 and pushes the protective member 38 in the horizontal direction, and the protective member 38 presses the switch module 7 to energize the circuit module, thereby ensuring the normal use of the tower fan 100. In the separated state, the metal spring 71 of the switch module 7 elastically recovers to a position away from the contact point, and pushes the protective member 38 to rotate in a direction away from the switch module 7, thereby ensuring that the switch module 7 is in a power-off state.

[0089] Reference Figure 7 , Figure 8 and Fig. 9 In some embodiments, the protective member 38 includes a rotating portion 381 and an extending portion 382. The rotating portion 381 is rotatably disposed on the housing 33, and the extending portion 382 is connected to the rotating portion 381. A water baffle 383 extending upward is provided on one side of the extending portion 382 facing the switch module 7, and the trigger member 68 is suitable for contacting the other side of the extending portion 382 to push the protective member 38 to rotate.

[0090] In the above technical solution, the protective member 38 is rotatably connected to the casing 33 through the rotating portion 381, which limits the movement mode of the protective member 38 and improves the stability of the protective member 38; a water baffle 383 is provided on the side of the extension portion 382 facing the switch module 7, which further reduces the possibility of contact between the liquid and the switch module 7, further improves the safety of the tower fan 100, and the contact area between the protective member 38 and the metal spring 71 is also increased through the water baffle 383, thereby improving the stability of the protective member 38 pressing the metal spring 71.

[0091] Reference Fig.10 , Fig.11 and Fig.14 In some embodiments, the tower fan 100 further includes: a first stopper 31 and a second stopper 5, one of which is disposed on the housing 1 and the other is disposed on the base 3. In addition to the assembled state and the separated state, the tower fan 100 also has a to-be-separated state.

[0092] In the assembled state, the housing 1 is placed on the top of the base 3, and the first stopper 31 and the second stopper 5 cooperate to limit the movement of the housing 1 relative to the base 3, so that the first part 200 is stably mounted on the second part 300; in the ready-to-separate state, the first stopper 31 is separated from the second stopper 5, so that the housing 1 can move relative to the base 3, that is, the first part 200 can move relative to the second part 300. That is to say, in the ready-to-separate state, the first stopper 31 and the second stopper 5 are released from limiting the housing 1, and the first part 200 can move relative to the second part 300 until it is completely separated from the second part 300.

[0093] As long as the first limit member 31 and the second limit member 5 can limit the movement of the shell 1 relative to the base 3 when they cooperate, the first limit member 31 can be set on the base 3 and the second limit member 5 can be set on the shell 1; or the first limit member 31 can be set on the shell 1 and the second limit member 5 can be set on the base 3.

[0094] Through the above technical solution, when the first part 200 is installed on the second part 300, the first limiting member 31 and the second limiting member 5 limit the first part 200, thereby enhancing the stability of the first part 200; and when the tower fan 100 in the utility model needs to disassemble the first part 200, it is only necessary to separate the first limiting member 31 and the second limiting member 5 to remove the first part 200 from the second part 300, and the disassembly operation of the first part 200 is simple and quick.

[0095] In some specific embodiments, referring to Fig.14 , the first limit member 31 is arranged on the base 3, referring to Fig.10 and Fig.11 , the second limiting member 5 is arranged on the housing 1 .

[0096] Reference Fig.11 , Fig.14 and Fig.16 In some embodiments, the first limiting member 31 is provided with a slot 311, and the second limiting member 5 includes a movable portion 51 and a first elastic member 52. The movable portion 51 can be triggered to move between an unlocking position and a locking position. In the unlocking position, the movable portion 51 is disengaged from the slot 311, and in the locking position, the movable portion 51 extends into the slot 311.

[0097] Reference Fig.11 , Fig.12 and Fig.13 The first elastic member 52 is connected to the movable portion 51 to apply a force to the movable portion 51 to move toward the locking position.

[0098] When the tower fan 100 is in the assembled state, the movable portion 51 is in the locked position, that is, the movable portion 51 extends into the slot 311, and the movable direction of the first part 200 is restricted, so that the first part 200 can be fixed to the second part 300. The first elastic member 52 also applies a force to the movable portion 51 to move toward the locked position, so that the movable portion 51 can be stably located in the slot 311, thereby enhancing the stability of the cooperation between the first limiting member 31 and the second limiting member 5, that is, improving the stability of the first part 200 installed on the second part 300.

[0099] When the tower fan 100 is in the to-be-separated state, the movable portion 51 is in the unlocked position, that is, the movable portion 51 is separated from the slot 311 , releasing the restriction on the first portion 200 , so that the first portion 200 can move relative to the second portion 300 .

[0100] Reference Figure 8 and Fig. 9 In some embodiments, the trigger member 68 is connected to the movable portion 51 to be linked with the movable portion 51 .

[0101] Because in the process of installing the first part 200 on the second part 300, it is necessary to move the movable part 51 so that the movable part 51 extends into the card slot 311 to fix the first part 200, and at the same time, it is necessary to move the trigger member 68 so that the trigger member 68 presses the switch module 7 to turn on the circuit module. In the embodiment of the utility model, by connecting the trigger member 68 with the movable part 51, only the trigger member 68 or only the movable part 51 needs to be moved to simultaneously achieve the fixation of the first part 200 and the power-on of the circuit module, which effectively improves the convenience of installing the first part 200.

[0102] Reference Figure 3 , Figure 4 and Fig.14In some embodiments, one of the housing 1 and the base 3 is provided with a plug-in portion 34 and the other is provided with a plug-in channel 16. In the assembled state, the plug-in portion 34 is plug-fitted with the plug-in channel 16.

[0103] In the above technical solution, the first part 200 and the second part 300 are not only plugged in and matched with each other through the mounting boss 36 and the mounting groove 66 , but also plugged in and matched with each other through the plug-in portion 34 , which further improves the stability of the connection between the first part 200 and the second part 300 .

[0104] Reference Figure 3 , Figure 4 and Fig.14 In some embodiments, a mounting boss 36 is provided on the top of the base 3, and the cross-section of the mounting boss 36 in the vertical direction is circular, a plug-in portion 34 is provided on the peripheral side of the mounting boss 36, a mounting groove 66 is provided on the bottom of the housing 1, a plug-in channel 16 is provided on the peripheral side of the mounting groove 66, and the plug-in portion 34 is plugged into and matched with the plug-in channel 16.

[0105] Reference Fig.10 , Fig.11 and Fig.14 In some specific embodiments, the lower shell 15 of the housing 1 is provided with an inserting channel 16 , a movable portion 51 and a first elastic member 52 , and the top of the base 3 is provided with an inserting portion 34 and a card slot 311 .

[0106] When installing the first part 200 on the second part 300, the first part 200 is moved from top to bottom until the plug-in portion 34 of the base 3 is inserted into the plug-in channel 16 of the shell 1. When the plug-in portion 34 is located in the plug-in channel 16, the shell 1 can only move in the up and down directions. When the shell 1 is installed in place, the movable portion 51 is triggered so that the movable portion 51 extends into the slot 311, limiting the up and down movement of the shell 1, thereby fixing the shell 1 on the base 3, that is, installing the first part 200 on the second part 300.

[0107] Reference Fig.14 , Fig.15 and Fig.16 In some embodiments, at least a portion of the movable portion 51 is located in the plug-in channel 16 in the locked position, and the plug-in portion 34 is disposed on the side of the first limit member 31 facing the plug-in channel 16. When the plug-in portion 34 is inserted into the plug-in channel 16, the plug-in portion 34 pushes the movable portion 51 to move toward the unlocked position.

[0108] In the above technical solution, the plug-in portion 34 is arranged on the side of the first stopper 31 facing the plug-in channel 16, because the first stopper 31 is provided with a card slot 311, that is, the card slot 311 is located on the side of the plug-in portion 34 away from the plug-in channel 16. When the plug-in portion 34 is located in the plug-in channel 16, the movable portion 51 can be moved to be partially located in the plug-in channel 16 and extend into the card slot 311, and the movable portion 51 blocks the movement of the plug-in portion 34 toward the side away from the plug-in channel 16, so that the first part 200 can be fixed on the second part 300.

[0109] Because the first elastic member 52 always exerts a force on the movable portion 51, when the first part 200 is at a position away from the second part 300, under the force exerted by the first elastic member 52, the movable portion 51 is also in the locked position, that is, at least a part of the movable portion 51 is located in the insertion channel 16. In the embodiment of the utility model, when the plug-in portion 34 is inserted into the insertion channel 16, the plug-in portion 34 pushes the movable portion 51 to move toward the unlocked position to prevent the movable portion 51 from affecting the insertion of the insertion portion. When the plug-in portion 34 is fully inserted into the insertion channel 16, the first part 200 is installed in place, and the movable portion 51 is just opposite to the card slot 311. Under the force of the first elastic member 52, the movable portion 51 automatically moves into the card slot 311, thereby fixing the first part 200 to the second part 300.

[0110] With the above technical solution, when installing the first part 200, the user only needs to completely insert the plug-in portion 34 into the plug-in channel 16, and the movable portion 51 will automatically be inserted into the card slot 311 to fix the first part 200, making the installation operation more convenient and quick.

[0111] Reference Fig.14 , Fig.15 and Fig.16 In some specific embodiments, the plug-in portion 34 is provided with a guide slope 341 , and the guide slope 341 extends obliquely to be suitable for slidingly cooperating with the movable portion 51 to push the movable portion 51 to move when the plug-in portion 34 is inserted into the plug-in channel 16 .

[0112] When the first part 200 is at a position away from the second part 300, under the force applied by the first elastic member 52, part of the movable part 51 is located in the insertion channel 16, and at this time, a gap is left between the end of the movable part 51 and the inner wall of the insertion channel 16 for the top end of the plug-in part 34 to enter. When the top end of the plug-in part 34 enters the gap, the guide slope 341 of the plug-in part 34 contacts the movable part 51, and as the plug-in part 34 continues to penetrate deeper into the insertion channel 16, the guide slope 341 continuously pushes the movable part 51 to move toward the unlocking position until the plug-in part 34 completely enters the insertion channel 16, and the movable part 51 is opposite to the card slot 311. Under the force of the first elastic member 52, the movable part 51 automatically moves into the card slot 311, thereby fixing the first part 200 to the second part 300.

[0113] In the above technical solution, the guide slope 341 can be used to push the movable part 51 to move when the plug-in part 34 is inserted into the plug-in channel 16, thereby improving the smoothness of pushing the movable part 51 to move. In addition, the guide slope 341 has a simple structure and is easy to form, thereby reducing the cost of the tower fan 100.

[0114] Reference Fig.14 , Fig.15 and Fig.16 In some embodiments, the extension direction of the plug-in channel is a vertical direction, and the movable direction of the movable portion 51 is a horizontal direction, so that the movable portion 51 can move into the plug-in channel or away from the plug-in channel.

[0115] The included angle between the guiding inclined surface 341 and the vertical direction is K, and in the embodiment of the utility model, 30°≤K≤45°.

[0116] According to the above technical solution, if K is greater than 45°, when the guide bevel 341 pushes the movable part 51, the friction between the guide bevel 341 and the movable part 51 is relatively large, the pushing smoothness is relatively low, and it is easy to cause wear of parts. If K is less than 30°, it will affect the structural strength of the plug-in part itself. The embodiment of the utility model limits the angle of the guide bevel 341 to 30°≤K≤45°, which ensures the smoothness of the guide bevel 341 pushing the movable part 51 to move while also ensuring the structural strength of the plug-in part.

[0117] In some specific embodiments, K is 40°. In some other embodiments, K may also be other angles such as 30°, 35°, or 45°.

[0118] Reference Fig.14 , Fig.15 and Fig.16In some specific embodiments, the plug-in portion 34 is constructed as a right-angled triangle structure, the hypotenuse of the plug-in portion 34 is formed as a guide slope 341, one right-angled side of the plug-in portion 34 is in contact with the inner wall of the plug-in channel 16, and the other right-angled side of the plug-in portion 34 is spaced apart from the top surface of the base 3 to form a card slot 311.

[0119] The plug-in portion 34 in the above technical solution has a simple structure and is easy to produce, thereby reducing the cost of the tower fan 100.

The movable portion 51 is movably disposed in the dial housing 6, and the first elastic member 52 applies a force to the movable portion 51. By disposing the second position-limiting member 5 in the dial housing 6, the risk of interference between other external structures and the movable portion 51 or the first elastic member 52 is reduced, and the working stability of the second position-limiting member 5 is improved.

[0128] In the above technical solution, the possibility of the plug-in portion 34 being separated from the plug-in channel 16 is further reduced through the limiting cooperation of the multiple movable portions 51 and the multiple card slots 311, thereby improving the stability of the connection between the housing 1 and the base 3.

[0129] The multiple movable parts 51 are all arranged on the movable dial 53, so that the movable dial 53 can drive the multiple movable parts 51 to move synchronously. When the user drives the movable dial 53 to move through the toggle part 54, the multiple movable parts 51 are all moved under the drive of the movable dial 53, that is, the user controls the movement of the toggle part 54 to trigger the movement of the multiple movable parts 51, thereby improving the convenience of the user in moving the multiple movable parts 51.

[0130] The first elastic member 52 is connected to the dial housing 6 and the movable dial 53 respectively, so that the first elastic member 52 applies a force to the movable dial 53 so that the plurality of movable parts 51 have a movement tendency to move to the locking position.

[0131] When the second position-limiting member 5 (including the movable portion 51, the movable dial 53 and the toggle portion 54) is not affected by external force, the plurality of movable portions 51 are located at the locked position under the action of the first elastic member 52. When the toggle portion 54 is toggled or the movable portion 51 is pushed by the guide slope 341, the plurality of movable portions 51 move synchronously toward the unlocked position.

The movable dial 53 is provided with a plurality of movable parts 51, and the plurality of movable parts 51 correspond to the plurality of slots 311. When the movable dial 53 rotates, the plurality of movable parts 51 are driven to move.

[0135] The shifting portion 54 is at least partially exposed to the outside of the dial housing 6 , so that the user can drive the movable dial 53 in the dial housing 6 to rotate through the shifting portion 54 .

[0139] Reference Fig.11 , Fig.12 and Fig.13 The first spring is suitable for pulling the second fixed column 531 toward the first fixed column 61. When the movable portion 51 moves toward the unlocking position, the second fixed column 531 moves in a direction away from the first fixed column 61, and the first spring elastically stretches. When the second position-limiting member 5 (including the movable portion 51, the movable dial 53 and the toggle portion 54) is not affected by external force, the first spring elastically recovers and pulls the second fixed column 531 to move in a direction close to the first fixed column 61, so as to drive the movable dial 53 to move, thereby driving the multiple movable portions 51 to move toward the locking position.

When the movable portion 51 is in the unlocking position, the elastic rubber member or the compression spring is compressed and shortened. When the second position-limiting member 5 (including the movable portion 51, the movable dial 53 and the toggle portion 54) is not affected by external force, the elastic rubber member or the compression spring elastically stretches to push the movable portion 51 to move toward the locking position.
