The body 1 is provided with a drive assembly; the telescopic assembly 4 includes a movable rod 42 and a fixed rod 41, the movable rod 42 is connected to the control component 3, and the fixed rod 41 is connected to the body 1, and the movable rod 42 can be telescoped relative to the fixed rod 41 to form a mounting portion between the control component 3 and the body 1; the air supply assembly can be detachably mounted on the mounting portion and is transmission-connected to the drive assembly.

[0041] Based on the above structure, when using the tower fan of the present invention, a mounting portion is formed between the control member 3 and the body 1 for mounting the air supply assembly, facilitating disassembly and assembly of the air supply assembly for cleaning and maintenance, and also avoiding the risk of losing the control member 3 during operation or disassembly. Furthermore, the use of the telescopic assembly 4 increases the adjustable flexibility of the mounting portion, accommodating the needs of air supply assemblies of different sizes, thereby enhancing the versatility and practicality of the device and optimizing the user experience.

[0042] In this embodiment, the movable rod 42 has a first end and a second end, the control member 3 is connected to the second end, and the fixed rod 41 is fixed on the body 1; a first connecting cavity 411 is provided in the fixed rod 41; the movable rod 42 is movably connected from the first end to the first connecting cavity 411 and can move along the axial direction of the fixed rod 41.

[0043] See Figure 3 The tower fan of the present invention also includes a first locking mechanism, which includes a first locking piece and a second locking piece. The first locking piece is arranged on the first end and is connected to the first connecting cavity 411. The second locking piece is arranged on the fixed rod 41; when the movable rod 42 moves axially relative to the fixed rod 41, the first locking piece and the second locking piece are locked with each other to limit the movable position of the movable rod 42 and the fixed rod 41.

[0044] In this embodiment, the first locking member is a locking pin 424 installed on the first end, and the second locking member is a locking hole 412 opened on the fixed rod 41; when the movable rod 42 moves axially relative to the fixed rod 41, the locking pin 424 can extend into the locking hole 412 to achieve locking.

[0045] It should be noted that, in other cases, the locking matching structure of the lock pin 424 and the lock hole 412 may also have a locking structure such as a snap-fit ​​structure with a limit groove, and is not limited thereto and can be selected according to actual use.

[0046] Furthermore, in this embodiment, at least two locking holes 412 are provided to facilitate the position of the movable rod 42 relative to the fixed rod 41 when the movable rod 42 is extended and retracted relative to the fixed rod 41, thereby forming the mounting portion at different heights to install different air supply components.

[0047] In this embodiment, the tower fan of the present invention also includes an unlocking member, a second connecting cavity 421 is provided in the movable rod 42, and the unlocking member includes a pushing rod 422 and a first button 311 arranged at one end of the pushing rod 422, and the other end of the pushing rod 422 is connected to the locking pin 424; when the first button 311 is pressed down by an external force, one end of the pushing rod 422 drives the other end of the pushing rod 422 to push the locking pin 424 out of the lock hole 412 to achieve unlocking.

[0048] Specifically, in this embodiment, the unlocking member also includes a pressing block 423, one end of which is fixedly connected to the other end of the pressing rod 422, and the other end of which is connected to the locking pin 424 wedge block. When the first button 311 is pressed under the action of external force, the pressing block 423 at the other end of the pressing rod 422 drives the locking pin 424 to disengage from the lock hole 412 by wedge movement to achieve unlocking, thereby changing the telescopic movement of the movable rod 42 relative to the fixed rod 41, and further changing the height of the mounting portion formed between the control member 3 and the body 1, so that the air supply component can be disassembled for cleaning and maintenance or replacement of air supply components of different heights, to meet the needs of air supply components of different sizes, enhance the versatility and practicality of the equipment, and optimize the user experience.

[0049] In this embodiment, a cavity 31 is defined on the control member 3 , and the first button 311 is disposed in the cavity 31 .

[0050] It should be noted that, in other cases, a driving component, such as a small motor, can be added to drive the lock pin 424 out of the lock hole 412, and the small motor can be electrically connected to the control component 3 to achieve control, so as to facilitate user operation.

[0051] Of course, in other cases, the movable rod 42 in the telescopic assembly 4 can be telescoped relative to the fixed rod 41 and a motor or a driving member can be added for use, and the present invention is not limited thereto.

[0052] In this embodiment, the air supply assembly includes a shell 2 and an impeller 22 arranged in the shell 2, and the shell 2 is provided with an air inlet 25 and an air outlet 26 for air flow, and the shell 2 is provided with a groove 21; when the air supply assembly is installed on the mounting part, the movable rod 42 and the fixed rod 41 are clamped in the groove 21.

[0053] See Figure 4-6 The top of the housing 2 is further provided with a positioning groove 27 , and the bottom of the control member 3 is provided with a positioning column 32 ; when the air supply assembly is installed on the mounting portion, the positioning column 32 is engaged with the positioning groove 27 .

[0054] When in use, the movable rod 42 and the fixed rod 41 can be easily snapped into the groove 21. At the same time, the precise snapping of the positioning column 32 and the positioning groove 27 further improves the reliability and convenience of the installation of the air supply component, effectively reducing the installation difficulty between the air supply component and the installation part, which not only simplifies the user operation, but also reduces the time consumption during the installation process.

[0055] In this embodiment, the drive assembly includes a drive motor 5 arranged on the body 1 and a drive shaft 51 arranged on the output shaft of the drive motor 5, and the body 1 is provided with a heat dissipation hole 12 for dissipating heat from the drive motor 5, and the shell 2 is provided with a transmission shaft 231 that is transmission-connected to the impeller 22; when the air supply assembly is installed on the mounting portion, the transmission shaft 231 is transmission-connected to the drive shaft 51.

[0056] It should be noted that in this embodiment, the transmission shaft 231 and the drive shaft 51 are connected via toothed meshing.

Furthermore, this structure reduces energy loss, ensures efficient power transmission, and thus improves the operational reliability of the equipment. Furthermore, the toothed meshing method offers excellent durability, significantly extending the service life of the detachable transmission components.

[0057] See Figure 6 The tower fan of the present invention also includes a second locking mechanism, which includes a locking block 232 and a locking slot 131. A slot 23 is opened on the shell 2, and an insert block 13 is provided on the body 1; the locking block 232 is arranged in one of the slot 23 or the insert block 13, and the locking slot 131 is arranged in the other of the slot 23 or the insert block 13; when the air supply assembly is installed on the mounting portion, the insert block 13 is plugged into the slot 23, and the locking block 232 and the lock slot 131 are locked with each other.

[0058] It should be noted that, in other cases, the slot 23 and the insert block 13 may also be swapped, that is, the slot 23 is opened on the body 1 and the insert block 13 is set on the shell 2. This is not limited to this and can be selected according to actual conditions.

[0059] In this embodiment, the housing 2 is further provided with a second button 24 connected to a locking block 232. When the second button 24 is pressed under external force, the locking block 232 and the locking slot 131 are unlocked. Specifically, the locking block 232 is a spring-loaded latch. During use, the housing 2 and the housing 1 in the air supply assembly are quickly aligned by sliding the insert 13 into the slot 23. That is, the air supply assembly is installed on the mounting portion, and then the locking block 232 is locked into the locking slot 131 to ensure a secure connection. This effectively improves the stability of the connection between the air supply assembly and the housing 1, preventing loosening or displacement. At the same time, it also enhances the reliability of the transmission connection between the transmission shaft 231 and the drive shaft 51.

[0060] It should be noted that in this embodiment, the number of locking blocks 232 and locking slots 131 is set to at least two to enhance the stability of the connection between the air supply assembly and the body 1. This multi-point locking design not only effectively prevents loosening of the connection, but also further improves the stability of the drive motor 5 when driving the impeller 22 to rotate and blow air, thereby significantly reducing vibration and noise during operation. In addition, this design extends the service life of the device and improves overall operating efficiency, providing users with a smoother and more comfortable user experience.

[0061] In this embodiment, a base 11 is provided at the bottom of the body 1 to improve the stability of the device. The base not only effectively enhances the stability of the device during operation, but also reduces the risk of displacement or tipping due to vibration, thereby ensuring the safe use of the device.

[0062] In summary, the tower fan of the present invention forms a dedicated mounting portion between the control member 3 and the body 1 for mounting the air supply assembly. This facilitates assembly and disassembly of the air supply assembly for cleaning and maintenance, and also avoids the risk of loss of the control member 3 during operation or disassembly. Furthermore, the use of the telescopic assembly 4 increases the adjustable flexibility of the mounting portion, accommodating air supply assemblies of different sizes, thereby enhancing the versatility and practicality of the device and optimizing the user experience.

[0063] This tower fan features a recess 21 formed in the housing 2, allowing the movable rod 42 and the fixed rod 41 to be easily snapped into place within the recess 21. Furthermore, the precise snap-fitting of the positioning post 32 into the positioning slot 27 further enhances installation reliability and convenience, effectively reducing the difficulty of installing the air supply assembly and the mounting portion. This not only simplifies user operation but also reduces installation time. Furthermore, the robust snap-fit ​​structure ensures safety and stability during operation, thereby enhancing the overall user experience and product performance.

[0064] This tower fan achieves rapid alignment through the sliding engagement of the insert 13 and the slot 23. The locking block 232 and the locking slot 131 lock securely together, effectively improving the stability of the connection between the air supply assembly and the fan body 1 and preventing loosening or displacement. This also enhances the reliability of the transmission connection between the transmission shaft 231 and the drive shaft 51, reducing mechanical failures during power transmission, further optimizing the operating efficiency and service life of the device, and significantly improving overall performance and user experience.
