Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0058] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0059] The following is for reference. Figures 1-15 A fan 100 according to an embodiment of the present invention is described. The fan 100 is provided with a child lock component 3 and a micro switch 23. The child lock component 3 can be used to trigger the micro switch 23 to selectively control the power state of the drive component of the fan 100, avoid accidental triggering by children, and improve the safety of using the fan 100.

[0060] like Figures 1-15 As shown, a fan 100 according to an embodiment of the present invention includes a fan head 1, a motor base 2, and a child lock component 3.

[0061] The fan head 1 contains fan blades 11, and the motor base 2 is connected to the fan head 1, with a drive component inside the motor base 2. In practical design, the drive component can be a motor, which outputs driving force, and the motor shaft can be connected to the fan head 1 to drive the fan blades 11 to rotate. Furthermore, the motor base 2 can be mounted on a surface, or as... Figure 1 and Figure 2As shown, a base 4 is provided below the motor base 2 for mounting on a surface. The vertical height of the base 4 can be set to a larger value, placing both the motor base 2 and the fan head 1 at a relatively high position within the space, thus facilitating airflow delivery to the user. Alternatively, the vertical height of the base 4 can be set to a smaller value, raising the height of the motor base 2 and the fan head 1 relative to the surface. This allows for flexible placement of the motor base 2 directly on the surface, enabling desktop mounting or even wall mounting. Furthermore, the overall height of the fan 100 can be flexibly adjusted using bases of varying heights, making it suitable for different application scenarios and meeting diverse user needs. The surface can be the ground or a desktop, etc.

[0062] The fan head 1 is detachably connected to the motor base 2, so that the fan head 1 can be disassembled independently relative to the motor base 2. This allows the fan head 1 to be removed independently for cleaning and replacement, which helps reduce operating costs and maintains good air quality output after cleaning.

[0063] After the motor base 2 and the fan head 1 are connected, the motor shaft is powered to the fan blade 11. At this time, the fan blade 11 can be driven to rotate after the motor is turned on. In other words, the power connection between the drive component and the fan blade 11 can be achieved at the same time as the fan head 1 is connected to the motor base 2. That is, after the motor base 2 and the fan head 1 are separated, the power connection between the drive component and the fan blade 11 is disconnected, so as to realize the simultaneous installation and disassembly of the two sets of structures.

[0064] The motor base 2 is equipped with a micro switch 23, which is used to control the power state of the drive component. This means that the drive component can be turned on or off by controlling the micro switch 23. The micro switch 23 can be configured as either a normally off switch or a normally on switch. Users can actively operate the micro switch 23 to flexibly switch the power state of the drive component, thereby flexibly selecting the drive state of the fan blade 11. It should be noted that the micro switch 23 can be used to directly start or stop the drive component; it can also be used to control the working circuit of the drive component. For example, when the micro switch 23 is open, the working circuit cannot be connected or closed, while when the micro switch 23 is closed, the working circuit can be connected or closed, flexibly switching the working state of the drive component and the fan blade 11.

[0065] The child lock component 3 is movably mounted on the motor mount 2 and is used to selectively lock with the fan head 1. When the child lock component 3 is movable relative to the motor mount 2, it also selectively triggers the micro switch 23. That is, by moving the child lock component 3, the micro switch 23 is opened or closed, thereby controlling the power output state of the drive component. In other words, the user can drive the child lock component 3 in one direction relative to the motor mount 2 to selectively trigger the micro switch 23, or drive it in another direction relative to the motor mount 2 to prevent contact between the child lock component 3 and the micro switch 23, thus selecting not to trigger the micro switch 23. It should be noted that the micro switch 23 can be built into the motor mount 2 so that users, including children, cannot touch the micro switch 23, avoiding safety issues caused by direct contact. The child lock component 3 can be used both to lock the connection between the motor mount 2 and the fan head 1, and to trigger the micro switch 23 to control the power output of the drive component.

[0066] Therefore, in actual use, the user connects the motor mount 2 to the fan head 1. After connection, the child lock component 3 can be moved relative to the motor mount 2 to lock the motor mount 2 and the fan head 1, preventing the fan head 1 and motor mount 2 from automatically separating during fan 100 use. At the same time, the child lock component 3 pushes the micro switch 23 to activate the drive mechanism, thereby enabling the fan blades 11 to be driven. When the user disassembles the fan head 1, the child lock component 3 can be operated first to unlock the fan head 1 relative to the motor mount 2, facilitating the individual disassembly of the fan head 1. Simultaneously, the micro switch 23 is no longer subjected to the force of the child lock component 3 and resets, thereby disconnecting the power to the drive mechanism and stopping the fan blades 11 from rotating.

[0067] In other words, when the user disassembles the fan head 1 relative to the motor base 2, the child lock component 3 unlocks the fan head 1 relative to the motor base 2. At the same time, by acting on the micro switch 23, the drive component stops outputting driving force, so that the drive component is in a state of stopping power output during the disassembly of the fan head 1. This prevents the active action of the drive component from causing damage to the user when the user disassembles the fan head 1. Moreover, when the drive component drives the fan blade 11 to rotate, the fan head 1 and the motor base 2 are already in a stable connection state, which can provide better protection for children and improve the safety of using the fan 100.

[0068] According to an embodiment of the present invention, the fan 100 is equipped with a child lock component 3 and a micro switch 23 to cooperate so that when the user disassembles the fan head 1, the power of the drive component can be automatically cut off, and after the fan head 1 is installed with the motor base 2, the drive component can be automatically connected, thereby avoiding damage to the user from the drive component and the rotating fan blades 11, and improving the safety of using the fan 100.

[0069] In some embodiments, the child lock component 3 includes a sliding paddle 31 and a locking pin 33. Both the sliding paddle 31 and the locking pin 33 are movably mounted on the motor base 2. The sliding paddle 31 and the locking pin 33 are slidably engaged. The sliding paddle 31 is adapted to selectively lock the locking pin 33 with the fan head 1 when it is moving relative to the motor base 2.

[0070] In other words, the sliding paddle 31 and the locking pin 33 can move relative to the motor base 2 respectively, and they can move relative to the motor base 2 in different directions. The sliding paddle 31 drives the locking pin 33 by utilizing the direction of the sliding engagement.

[0071] The sliding paddle 31 is the driving component, and it is at least partially exposed outside the motor base 2, allowing the user to actively operate it. This enables the user to flexibly operate the sliding paddle 31 to drive the locking pin 33. The locking pin 33 is the driven component. When the sliding paddle 31 moves, the locking pin 33 moves relative to the motor base 2 under its influence. The locking pin 33 has a locked position and an unlocked position relative to the motor base 2. When the locking pin 33 is in the locked position, it can limit and fix the fan head 1 to the motor base 2, thus locking the fan head 1 relative to the motor base 2. In this position, the user cannot disassemble the fan head 1 relative to the motor base 2. When the locking pin 33 is in the unlocked position, the fan head 1 is unlocked relative to the motor base 2, allowing the user to flexibly disassemble the fan head 1.

[0072] Furthermore, in the specific construction, the motor base 2 can be rotatably screwed onto the fan head 1, allowing the fan head 1 to be rotatably mounted on the motor base 2. Simultaneously, a locking port 13 can be provided on the fan head 1. After the fan head 1 rotates to its position relative to the motor base 2, the locking pin 33 can extend into the locking port 13 and restrict the fan head 1 from rotating in the opposite direction relative to the motor base 2, preventing the fan head 1 from automatically rotating and disassembling relative to the motor base 2. During disassembly, the locking pin 33 can be extended from the locking port 13 via the sliding paddle 31. At this time, the locking pin 33 no longer has a circumferential limiting effect on the fan head 1, thus allowing the fan head 1 to be disassembled relative to the motor base 2. The structure is simple and facilitates flexible locking and unlocking of the fan head 1 and the motor base 2.

[0073] In some embodiments, the sliding paddle 31 is slidable along the circumference of the motor base 2. A circumferentially extending mounting groove may be provided on the motor base 2, through which the sliding paddle 31 passes and is mounted. The sliding paddle 31 can slide relative to the motor base 2 along the mounting groove. Furthermore, when the user operates the child lock component 3, the sliding paddle 31 can be directly pushed to move relative to the motor base 2.

[0074] Furthermore, the locking pin 33 slides radially or vertically along the motor base 2. This allows the locking pin 33 to move radially inward or outward relative to the motor base 2, enabling it to reach different positions. One of the sliding paddle 31 and the locking pin 33 is provided with a sliding guide groove 316, and the other with a sliding guide rail 332. The sliding paddle 31 and the locking pin 33 are slidably engaged via the sliding guide rail 332 and the sliding guide groove 316. In other words, the sliding direction of the locking pin 33 relative to the motor base 2 can be flexibly set. Preferably, the locking pin 33 slides vertically relative to the motor base 2. This allows the locking pin 33 to slide downward relative to the motor base 2 under gravity when moving, improving the reliability of its downward movement.

[0075] Therefore, when the sliding paddle 31 moves relative to the motor base 2, the inner wall surfaces of the sliding guide rail 332 and the sliding guide groove 316 are in contact to realize the driving effect of the sliding paddle 31 on the locking pin 33. The structure is simple and the matching method is easy to realize.

[0076] It should be noted that, in actual design, the locking pin 33 can move radially or vertically along the motor base 2, to increase the flexibility and overcome limitations of the actual design. Figure 11 As shown, the movement direction of the locking pin 33 is along the up and down direction in the figure, and the up and down direction forms a certain angle with the radial line where the locking pin 33 is located, which can also achieve locking of the fan head 1.

[0077] In some embodiments, a sliding guide groove 316 is provided on the sliding paddle 31, and a sliding guide surface 317 is formed within the sliding guide groove 316, the sliding guide surface 317 pressing against the locking pin 33. That is, the sliding paddle 31 can be constructed as a hollow structure so that a sliding guide groove 316 is formed within the sliding paddle 31. Specifically, for example... Figure 12 As shown, the sliding paddle 31 includes two opposing inner walls, and each inner wall is provided with a sliding guide groove 316. Meanwhile, as... Figure 13 As shown, a sliding guide rail 332 is provided on both sides of the outer end of the locking pin 33. In actual installation, the outer end of the locking pin 33 is extended into the sliding paddle 31 to achieve sliding engagement between the two. The two sets of sliding guide grooves 316 and sliding guide rails 332 cooperate to ensure the support stability of the locking pin 33 and increase the contact area to achieve effective driving of the locking pin 33.

[0078] The distance from the sliding guide surface 317 to the axis of the motor base 2 is set to gradually increase along the circumference of the motor base 2. In other words, the sliding guide surface 317 is constructed as a curved surface, and when the sliding paddle 31 moves along the circumference of the motor base 2, the sliding guide surface 317, by utilizing its own inclined and curved configuration, can push the locking pin 33 to move radially relative to the motor base 2. Specifically, if the distance from the sliding guide surface 317 to the axis of the motor base 2 is set to gradually increase along the clockwise direction of the motor base 2, when the sliding paddle 31 slides relative to the motor base 2 in a clockwise direction, the sliding guide surface 317 pushes the locking pin 33 to move radially inward along the motor base 2 to lock with the fan head 1; while when the sliding paddle 31 slides relative to the motor base 2 in a counterclockwise direction, the sliding guide surface 317 pushes the locking pin 33 to move radially outward along the motor base 2 to unlock with the fan head 1. The structure is simple and the driving process is easy to implement.

[0079] In some embodiments, the sliding paddle 31 is provided with a first limiting rib 311 and a second limiting rib 312. The first limiting rib 311 and the second limiting rib 312 are spaced apart and define a sliding guide groove 316. The sides of the first limiting rib 311 and the second limiting rib 312 facing each other are formed with sliding guide surfaces 317. That is, when the sliding paddle 31 moves relative to the motor base 2, the first limiting rib 311 and the second limiting rib 312 can push the locking pin 33 to move, thereby locking or unlocking the locking pin 33 with the fan head 1.

[0080] like Figure 11 As shown, a first limiting rib 311 and a second limiting rib 312 are provided on the inner wall of the sliding guide groove 316. The first limiting rib 311 and the second limiting rib 312 are spaced apart radially along the motor base 2, as shown. Figure 11 As shown, the first limiting rib 311 is located outside the second limiting rib 312. The sliding guide surface 317 of the first limiting rib 311 and the sliding guide surface 317 of the second limiting rib 312 are distributed opposite to each other. When the sliding paddle 31 moves along the circumference of the motor base 2, the locking pin 33 can be pushed from different directions by the two limiting ribs respectively.

[0081] Specifically, such as Figure 11 As shown, when the sliding paddle 31 rotates counterclockwise (to the left in the figure) along the motor base 2, the sliding guide surface 317 on the second limiting rib 312 pushes the sliding guide rail 332 of the locking pin 33, causing the locking pin 33 to move radially outward along the motor base 2, thereby unlocking the locking pin 33 from the fan head 1. When the sliding paddle 31 rotates clockwise (to the right in the figure) along the motor base 2, the sliding guide surface 317 on the first limiting rib 311 pushes the sliding guide rail 332 of the locking pin 33, causing the locking pin 33 to move radially inward along the motor base 2, thereby locking the locking pin 33 from the fan head 1. Thus, the locking pin 33 can be used to selectively lock or unlock the fan head 1.

[0082] In some embodiments, the sliding paddle 31 is provided with a locking tooth surface 313, which extends along the movement direction of the sliding paddle 31. The locking pin 33 is provided with an elastic element 34 and a pressing element 35. The elastic element 34 is connected between the locking pin 33 and the pressing element 35 and is used to press the pressing element 35 toward the locking tooth surface 313. In this way, the elastic force of the elastic element 34 can keep the pressing element 35 in contact with the locking tooth surface 313, so that when the sliding paddle 31 rotates relative to the motor base 2, the pressing element 35 can cooperate with the locking tooth surface 313 to produce a click, thereby enhancing the user's rotation feel.

[0083] like Figure 11 As shown, the locking tooth surface 313 is located inside the sliding paddle 31, and the locking tooth surface 313 is located on the side of the sliding paddle 31 facing the axis of the motor base 2. The outer end of the pressing member 35 can extend into the sliding paddle 31 to abut against the locking tooth surface 313. Thus, when the sliding paddle 31 slides along the circumference of the motor base 2, the outer end of the pressing member 35 can always abut against the locking tooth surface 313, and the pressing member 35 can produce a jerking sensation with the tooth surface when switching to different tooth positions, thereby enhancing the user's feel when pushing the sliding paddle 31.

[0084] It should be noted that the sliding paddle 31 includes a paddle body 314 and a paddle cover plate 315. The paddle cover plate 315 is connected to the paddle body 314. The paddle body 314 extends radially along the motor base 2, and the paddle cover plate 315 is connected to the side of the paddle body 314 facing away from the motor base 2, so that the side of the paddle body 314 facing away from the motor base 2 is in a closed state. Specifically, the first limiting rib 311 and the second limiting rib 312 are both provided on the paddle body 314, and the locking tooth surface 313 is provided on the side of the paddle cover plate 315 facing the inside of the paddle body 314. In other words, when the locking pin 33 extends into the sliding paddle 31, the locking pin 33 slides with the paddle body 314, and at the same time, the pressing member 35 inside the locking pin 33 presses against the paddle cover plate 315. Thus, the locking pin 33 can be effectively pushed, and a noticeable tactile feedback can be produced, improving the user experience.

[0085] In some embodiments, the locking tooth surface 313 extends circumferentially along the motor base 2, that is, the extension direction of the locking tooth surface 313 is the same as the movement direction of the sliding paddle 31 relative to the motor base 2. At the same time, the distance from the locking tooth surface 313 to the axis of the motor base 2 is set to gradually increase along the circumferential direction of the motor base 2. In other words, the extension direction of the locking tooth surface 313 is the same as the extension direction of the sliding guide groove 316, so that the pressing fit between the pressing member 35 and the locking tooth surface 313 can adapt to the fit between the locking pin 33 and the sliding guide groove 316.

[0086] like Figure 11As shown, the sliding guide surface 317 is configured such that its distance from the axis of the motor base 2 gradually increases from left to right. Simultaneously, the locking tooth surface 313 is also configured such that its distance from the axis of the motor base 2 gradually increases from left to right. It can be understood that when the locking pin 33 engages with the sliding guide groove 316, it moves radially as the position of the sliding guide surface 317 changes. Simultaneously, the pressing member 35 at the locking pin 33 presses against the locking tooth surface 313 under the force of the elastic member 34. By conforming the locking tooth surface 313 and the sliding guide surface 317, the distance between the locking pin 33 and the locking tooth surface 313 remains relatively uniform during radial movement. This allows the elastic member 34 to consistently provide a relatively balanced elastic force to the pressing member 35, thereby ensuring a relatively balanced pressing force between the pressing member 35 and the locking tooth surface 313. This maintains the tactile feedback of the pressing member 35 at different positions, guaranteeing the user's feel when pushing the sliding paddle 31.

[0087] In some embodiments, the locking pin 33 is provided with a mounting groove 331, which opens outward along the radial direction of the motor base 2. At least a portion of the pressing member 35 and the elastic member 34 are installed in the mounting groove 331, and one end of the elastic member 34 away from the pressing member 35 is connected to the inner bottom wall of the mounting groove 331, so that the pressing member 35 and the elastic member 34 always maintain a stable radial position in the mounting groove 331, and avoid the elastic member 34 from deforming radially, which would prevent it from providing effective elastic force.

[0088] Specifically, such as Figure 11 As shown, the upper end of the mounting groove 331 is open and the lower end is closed. The lower end of the pressing member 35 is located inside the mounting groove 331, and the elastic member 34 is located inside the mounting groove 331. The lower end of the elastic member 34 presses against the inner bottom wall of the mounting groove 331, and the upper end of the elastic member 34 presses against the pressing member 35, so that the pressing member 35 always maintains an upward pre-tightened state, and then extends to the outside of the mounting groove 331 to press against the locking tooth surface 313. The elastic member 34 will not bend radially when it is elastically deformed, and can stably apply an axial upward force to the pressing member 35 to ensure the pressing force of the pressing member 35 against the locking tooth surface 313.

[0089] In some embodiments, the end of the pressing member 35 is formed with a tapered pressing portion 351, which is adapted to press against the locking tooth surface 313, such as... Figure 11 As shown, the upper end of the pressing member 35 is constructed as a conical pressing part 351, and the tip of the conical pressing part 351 can be engaged in the groove of the locking tooth surface 313. As the sliding paddle 31 slides, the tip of the conical pressing part 351 can be switched to different grooves in sequence. By using the abrupt switching of the tip at the peak and trough of the groove, a distinct sense of abruptness is generated, which improves the user's feel.

[0090] And / or, a limiting ring 352 may be provided on the outer peripheral wall of the pressing member 35, and one end of the elastic member 34 is sleeved on the outside of the pressing member 35 and presses against the limiting ring 352, so that the limiting ring 352 can play a limiting role at the end of the elastic member 34, and at the same time, it also ensures that the elastic member 34 can apply a stable elastic force to the pressing member 35.

[0091] In actual construction, such as Figure 11 As shown, the pressing member 35 can be constructed so that the two ends are symmetrical with respect to the middle, that is, the limiting ring 352 is located in the middle of the length direction of the pressing member 35. The upper end and the lower end of the pressing member 35 are both formed with conical pressing parts 351. The upper conical pressing part 351 presses against the locking tooth surface 313, and the lower conical pressing part 351 presses against the inner bottom wall of the mounting groove 331. The elastic member 34 is sleeved outside the lower end of the pressing member 35, and the upper end of the elastic member 34 presses against the limiting ring 352, so that the pressing member 35 can also play a radial limiting role for the elastic member 34.

[0092] In some embodiments, the motor base 2 is provided with an outer insertion ring 22, and the fan head 1 is provided with an inner insertion ring 12, the inner insertion ring 12 being adapted to be inserted into the outer insertion ring 22, such as... Figure 2 As shown, the right end of the motor base 2 is provided with an external insertion ring 22. The external insertion ring 22 protrudes axially from the right end of the motor base 2 to form an insertion space within the external insertion ring 22. Meanwhile, as... Figure 3 As shown, an inner insertion ring 12 is provided at the left end of the fan head 1, and the inner insertion ring 12 protrudes axially from the left end of the motor base 2. The outer diameter of the inner insertion ring 12 is smaller than the inner diameter of the outer insertion ring 22, so that the inner insertion ring 12 can be inserted into the outer insertion ring 22 to achieve axial insertion between the motor base 2 and the fan head 1. Furthermore, a snap-fit ​​structure can be provided on the inner insertion ring 12 and the outer insertion ring 22 to ensure that they are locked together after insertion, preventing them from automatically disengaging and improving structural stability.

[0093] The locking pin 33 is slidably installed on the outer insertion ring 22. The locking pin 33 is inserted into and locked with the inner insertion ring 12 radially inward along the outer insertion ring 22 and unlocked with the inner insertion ring 12 radially outward. A locking port 13 is provided on the inner insertion ring 12. After the inner insertion ring 12 is inserted into the outer insertion ring 22, the locking pin 33 can be moved radially inward along the outer insertion ring 22 so that the inner end of the locking pin 33 is inserted into the locking port 13, thereby achieving the limiting and fixing of the outer insertion ring 22 and the inner insertion ring 12.

[0094] Specifically, the outer insertion ring 22 and the inner insertion ring 12 can be configured to be rotatably inserted. That is, after the inner insertion ring 12 is placed inside the outer insertion ring 22, it can be rotated relative to the outer insertion ring 22 until the locking port 13 and the locking pin 33 are directly opposite each other along the radial direction of the outer insertion ring 22. At this time, the locking pin 33 can be driven to move into the locking port 13 by the sliding paddle 31, so as to realize the insertion limit of the locking pin 33 in the locking port 13, thereby locking the fan head 1 and the motor base 2, preventing the fan head 1 from being automatically removed from the motor base 2, and improving the safety of the fan 100.

[0095] like Figure 3 As shown, a locking groove 121 is provided at the end of the inner insertion ring 12, and a locking slope 122 is provided in the locking groove 121. When the fan head 1 and the motor base 2 are rotated and connected, the locking slope 122 can gradually press the outer insertion ring 22 to achieve a tight connection between the fan head 1 and the motor base 2.

[0096] In some embodiments, the micro switch 23 is configured as a normally open switch, meaning that the micro switch 23 is in the open state when not subjected to external force. Specifically, when the sliding tab 31 moves relative to the motor mount 2, it can press against the micro switch 23 to open and conduct the micro switch 23. Figure 7 As shown, at this time, the sliding paddle 31 is in the right position, and there is no contact between the sliding paddle 31 and the micro switch 23. The micro switch 23 is in the open state, and the driving component has no power output. Further, as shown... Figure 8 As shown, the sliding paddle 31 moves to the left relative to the motor base 2, gradually acting on the micro switch 23 during the sliding process, causing the micro switch 23 to open and conduct, thereby enabling the drive unit to output power. Alternatively, the micro switch 23 is constructed as a normally open switch; in other words, the micro switch 23 is in the conducting state when not subjected to external force. When the sliding paddle 31 moves relative to the motor base 2, it can press against the micro switch 23 to open it, such as... Figure 7 As shown, at this time, the sliding paddle 31 is in the right position, and there is no contact between the sliding paddle 31 and the micro switch 23. The micro switch 23 is in the conducting state, and the driving component can output power at this time. Further, as shown... Figure 8 As shown, the sliding paddle 31 moves to the left relative to the motor base 2, so as to gradually act on the micro switch 23 during the sliding process, causing the micro switch 23 to open, thereby cutting off the power of the drive component.

[0097] In some embodiments, the micro switch is provided with a pressing spring 231, and the child lock component 3 is connected to a switch pressing block 32. The switch pressing block 32 and the pressing spring 231 are distributed circumferentially along the motor base 2, and the switch pressing block 32 is adapted to press or release the pressing spring 231 when the child lock component 3 moves relative to the motor base 2. Thus, when the child lock component 3 slides relative to the motor base 2, the switch pressing block 32 moves together with the child lock component 3 relative to the motor base 2, and gradually presses or releases the pressing spring 231 during the movement, thereby switching the working state of the micro switch 23.

[0098] Specifically, the sliding paddle 31 is connected to the switch block 32, and when the sliding paddle 31 drives the locking pin 33 to unlock the fan head 1, it is suitable to drive the switch block 32 to press the abutment spring 231. If the micro switch 31 is constructed as a normally open switch, when the sliding paddle 31 moves relative to the motor base 2, it drives the locking pin 33 to unlock the fan head 1. At the same time, the switch block 32 presses the abutment spring 231 of the micro switch 23, so that the abutment spring 231, after deformation, disconnects the micro switch 23, thereby cutting off the power output of the drive component and stopping the fan blade 11.

[0099] Similarly, when the sliding paddle 31 moves in the opposite direction, the sliding paddle 31 drives the locking pin 33 to lock with the fan head 1, and at the same time, it can drive the switch block 32 to activate the micro switch 23, thereby enabling the micro switch 23 to connect the power supply of the drive component, realize the power output of the drive component, and drive the fan blade 11 to rotate. The structure is simple and can realize the synchronous control of locking the motor base 2 and the fan head 1 as well as the driving force of the drive component, making it easy to operate.

[0100] In some embodiments, the sliding paddle 31 is slidable along the circumference of the motor base 2, and the switch block 32 is connected to the inner side of the sliding paddle 31. Specifically, as shown in the figure... Figures 4-5 , Figure 7-Figure 8 As shown, the switch block 32 is located inside the outer insertion ring 22 of the motor base 2, and the sliding paddle 31 is located outside the outer insertion ring 22. The switch block 32 passes through the outer insertion ring 22 to connect with the inner side of the sliding paddle 31. The switch block 32 protrudes and extends relative to the sliding paddle 31 toward a position close to the axis of the motor base 2, so that when the sliding paddle 31 moves, it can drive the switch block 32 to move within the outer insertion ring 22.

[0101] The switch block 32 and the pressing spring 231 are distributed around the axis of the motor base 2. That is, when the sliding paddle 31 moves along the circumference of the motor base 2, the switch block 32 also moves along the circumference of the motor base 2. The pressing spring 231 is located on the movement trajectory of the switch block 32, so that the switch block 32 can contact and separate from the pressing spring 231 as the sliding paddle 31 moves, thereby achieving effective control of the micro switch 23 and effectively controlling the power state of the driving component.

[0102] In some embodiments, the motor base 2 is provided with a pressing spring 21, which is used to lock the child lock component 3 when it moves to the unlock position, so that the child lock component 3 remains in a stable position when it moves to the unlock position, preventing the child lock component 3 from moving automatically relative to the motor base 2. In this way, when the fan head 1 is reinstalled and connected to the motor base 2, the position of the child lock component 3 is in the unlocked state, which is conducive to the reinstallation of the motor base 2 and the fan head 1.

[0103] Among them, such as Figure 5 and Figure 7 As shown, a pressing spring block 21 is provided in the plug ring of the motor base 2. The pressing spring block 21 is located in the movement direction of the child lock component 3. When the switch pressing block 32 is located in the plug ring and the sliding paddle 31 moves, it can drive the switch pressing block 32 to rotate around the axis of the motor base 2. Then, during the rotation, it gradually presses against the pressing spring block 21. The limiting structure on the pressing spring block 21 is used to achieve limiting and fixing, thereby locking the position of the child lock component 3.

[0104] In some embodiments, the pressing spring block 21 is provided with an elastic post 211, which can elastically extend and retract. The child lock component 3 is provided with a limiting port. When the child lock component 3 moves to the unlock position, the elastic post 211 extends into the limiting port. Thus, when the child lock component 3 is moved to the unlock position, the relative fixation of the two can be achieved through the limiting cooperation between the elastic post 211 and the limiting port, thereby locking the position of the child lock component 3.

[0105] Specifically, during actual installation, a spring can be installed on the elastic post 211, and a mounting hole is provided in the pressing spring block 21 so that one end of the elastic post 211 is elastically connected to the mounting hole through the spring, and the end of the elastic post 211 elastically extends out of the surface of the pressing spring block 21. When the child lock component 3 is moved toward the elastic post 211, the child lock component 3 pushes the elastic post 211 to retract, and when the elastic post 211 is aligned with the limiting port, the elastic post 211 elastically extends into the limiting port, thereby locking the position of the child lock component 3. When the user needs to lock the motor base 2 and the fan head 1 using the child lock component 3, the child lock component 3 can be pushed to move relative to the motor base 2, so that the pressing spring block 21 presses against the elastic post 211 and overcomes the elastic force of the spring, causing the elastic post 211 to retract, and the child lock component 3 to unlock relative to the pressing spring block 21. The structure is simple.

[0106] In some embodiments, the motor base 2 is provided with a first limiting part and a second limiting part, and the child lock component 3 is provided with a first engaging part and a second engaging part. The first limiting part is used to engage with the first engaging part in the unlocked position, and the second limiting part is used to engage with the second engaging part in the closed position, so that the first limiting part and the second limiting part engage and limit each other when the child lock component 3 moves to the two extreme positions, thereby ensuring that the relative position of the fan head 1 and the motor base 2 is more stable.

[0107] Specifically, when the child lock component 3 is in the unlocked position, the first limiting part and the first locking part engage to restrict the movement of the child lock component 3 relative to the motor base 2. At this time, the locking pin 33 and the switch pressure block 32 are both in a stable position relative to the motor base 2, making it easy for the user to connect and fix the fan head 1 to the motor base 2 at any time without any installation position mismatch. When the child lock component 3 is in the locked position, the second limiting part and the second locking part engage to restrict the movement of the child lock component 3 relative to the motor base 2. At this time, the locking pin 33 and the locking port 13 of the fan head 1 can be stably locked, and the contact state between the switch pressure block 32 and the micro switch 23 is stable, preventing the fan head 1 from separating from the motor base 2 and the interruption of the driving power, thus improving the safety and reliability of the structural design.

[0108] In some embodiments, the first limiting part is constructed as a limiting protrusion 221, and the first engaging part is constructed as a first hook 321. The first hook 321 has a hook groove, and the first hook 321 engages with the limiting protrusion 221 and the limiting protrusion 221 engages into the hook groove, thereby fixing the child lock component 3 and the motor base 2 in the unlocked position, ensuring that the motor base 2 can be quickly and efficiently connected and fixed when connected to the fan head 1.

[0109] Among them, such as Figure 7 As shown, a protruding limiting protrusion 221 is provided inside the outer insertion ring 22 of the motor base 2. The limiting protrusion 221 protrudes inward along the radial direction of the motor base 2, and at the same time... Figure 7 As shown, a first hook 321 is provided on the switch pressure block 32 of the child lock component 3. The first hook 321 is located at the left end of the switch pressure block 32, and the first hook 321 forms a hook groove that opens radially outward. When the child lock component 3 moves toward the unlock position, as shown... Figure 7 When the child lock moves from center to left, the first hook 321 moves to the left to a position directly opposite the limiting protrusion 221, so that the first hook 321 engages in the hook groove, so that the child lock component 3 is stably held in the left position, thereby locking the child lock component 3.

[0110] And / or, the second limiting part is constructed as a limiting block 222, and the second snap-fit ​​part is constructed as a second snap hook 322. The second snap hook 322 snaps and limits the limiting block 222, thereby making the child lock component 3 and the motor base 2 relatively fixed in the locking position, ensuring that the motor base 2 can be effectively connected and fixed to the fan head 1, and ensuring that the installation state of the fan head 1 on the motor base 2 is more stable.

[0111] like Figure 8 As shown, a protruding limiting block 222 is provided inside the outer insertion ring 22 of the motor base 2. The limiting block 222 and the limiting protrusion 221 are spaced apart in the circumferential direction of the outer insertion ring 22. The limiting block 222 protrudes inward along the radial direction of the motor base 2. Figure 7 As shown, a second hook 322 is provided on the switch pressure block 32 of the child lock component 3. The second hook 322 is located at the right end of the switch pressure block 32. When the child lock component 3 moves toward the unlock position, as shown... Figure 8 When the middle moves to the right, the second hook 322 moves to the right to the position directly opposite the limit block 222, so that the second hook 322 and the limit block 222 are stably engaged, so that the child lock component 3 is stably held in the right position, thereby locking the child lock component 3. At this time, the locking pin 33 can be stably locked with the fan head 1, ensuring the installation stability of the fan head 1 on the motor base 2.

[0112] It should be noted that in actual design, the limiting block 222 can be configured to cooperate with the locking pin 33. For example, the locking pin 33 can be installed inside the limiting block 222, so that the limiting block 222 can cooperate with both the locking pin 33 and the second hook 322, simplifying the structural design.

[0113] In some embodiments, an outer insertion ring 22 is formed at the end of the motor base 2, and an inner insertion ring 12 is formed on the fan head 1, the inner insertion ring 12 being inserted into the outer insertion ring 22; for example Figure 2 As shown, the right end of the motor base 2 is provided with an external insertion ring 22. The external insertion ring 22 protrudes axially from the right end of the motor base 2 to form an insertion space within the external insertion ring 22. Meanwhile, as... Figure 3 As shown, an inner insertion ring 12 is provided at the left end of the fan head 1, and the inner insertion ring 12 protrudes axially from the left end of the motor base 2. The outer diameter of the inner insertion ring 12 is smaller than the inner diameter of the outer insertion ring 22, so that the inner insertion ring 12 can be inserted into the outer insertion ring 22 to achieve axial insertion between the motor base 2 and the fan head 1. Furthermore, a snap-fit ​​structure can be provided on the inner insertion ring 12 and the outer insertion ring 22 to ensure that they are locked together after insertion, preventing them from automatically disengaging and improving structural stability.

[0114] Both the first and second locking parts extend into the outer insertion ring 22, and both the first and second limiting parts are located on the inner peripheral wall of the insertion space. Thus, the first locking part and the first limiting part perform locking and limiting within the insertion space, and the second locking part and the second limiting part also perform locking and limiting within the insertion space. This ensures that the limiting fit between the child lock component 3 and the motor base 2 is a built-in structure, avoiding the problem of easy failure of locking due to exposed locking structure, and improving the reliability of the child lock component 3.

[0115] In some embodiments, the fan 100 further includes a base 4, which is adapted to be supported on a placement surface. The motor mount 2 is mounted on the base 4, wherein the vertical height of the base 4 is greater than the vertical height of the motor mount 2, so that the motor mount 2 and the fan head 1 are both located at a higher position, which is conducive to the air blown out of the fan head 1 acting more efficiently on the user and improving the user's comfort.

[0116] like Figure 1 and Figure 2 As shown, a support plate 41 is formed at the lower end of the base 4. The support plate 41 has a large support area to ensure that the base 4 is stably supported on the ground. The motor base 2 is installed at the upper end of the base 4, and the fan head 1 is installed at the front end of the motor base 2. Whether the fan 100 is working or not, the base 4 supports the placement surface, which makes the fan 100 more stable. The base 4 can support the fan 100 on the placement surface, that is, the fan 100 can be placed on the ground. This type of floor fan is conducive to the overall stable placement of the fan 100.

[0117] The upper end of the base 4 can be rotatably connected to the motor base 2, so that the motor base 2 can rotate in different directions relative to the base 4, such as left and right or up and down, thereby meeting the user's wind power needs for the fan 100 in different directions and improving the user experience.

[0118] In some embodiments, the fan head 1 can be independently detached from the motor base 2, so that the fan head 1 can be completely and independently removed from the motor base 2. In this way, when cleaning the fan 100, the user can clean the fan head 1 independently, which not only improves cleaning efficiency, but also allows the user to increase the cleaning frequency, ensuring that the fan 100 can always blow out a refreshing and clean air, thus improving the user experience.

[0119] It should also be noted that, in the actual design, the fan head 1 and its internal fan blades and other structural components can be considered as a whole. At the same time, the motor base 2 and its internal motor and other structural components can be considered as a whole. When the fan head 1 and the motor base 2 are disassembled and installed as a whole, the fan head 1's mesh cover and the motor base 2's housing can be directly disassembled or connected. The disassembly structure is simple and the connection relationship is not complicated, which greatly reduces the disassembly time of the fan head 1 relative to the motor base 2. In addition, after the fan head 1 is removed from the motor base 2 as an independent unit, the user can clean the fan head 1 as a whole, or disassemble and clean the internal structural components of the fan head 1, thus meeting the user's cleaning needs.

[0120] In some embodiments, the fan head 1 is provided with an air outlet, and the fan blade 11 is constructed as an axial flow fan blade, which is adapted to drive the airflow within the fan head 1 to flow along the axial direction of the axial flow fan blade towards the air outlet. That is to say, the fan blade of the fan 100 in this invention is different from the traditional centrifugal fan blade, and can realize axial air intake and axial air exhaust. In actual operation, the axial flow fan blade rotates, and drives the airflow behind the axial flow fan blade to flow forward along its axial direction, and then flows to the air outlet at the front of the fan head 1 to be delivered toward the user's face.

[0121] It should be noted that the fan head 1 can be equipped with an air inlet. The air inlet can be located on the rear side of the fan head 1 for axial air intake, or on the outer circumferential side of the fan head 1 for oblique air intake. Both can achieve the air intake function of the fan head 1. The airflow entering the fan head 1 can flow to the axial rear end of the axial fan blade, and then flow forward along the axial direction to the air outlet under the action of the axial fan blade. In particular, the air inlet can be set on the rear side of the fan head 1, and a heat dissipation channel is set in the motor base 2, so that the heat dissipation channel is connected to the air inlet. Then, under the driving action of the axial fan blade, the airflow is driven to dissipate heat on the driving components and other components in the heat dissipation flow before flowing to the user through the air inlet. This not only facilitates air delivery, but also achieves internal heat dissipation of the motor base 2.

[0122] In some embodiments, the radial dimension of the fan head 1 is greater than or equal to twice the radial dimension of the motor base 2 at the location of the drive component, and / or the ratio of the radial dimension to the axial dimension of the fan head 1 is greater than or equal to 1. Therefore, the fan in this invention differs from a traditional cross-flow impeller. It should be noted that traditional tower fans use cross-flow impellers, and the radial dimension of the tower fan does not change significantly at various axial positions, while the radial dimension of the fan head 1 in this invention is much larger than the radial dimension of the motor base 2 at the drive component.

[0123] Meanwhile, the axial fan blades, compared to centrifugal fan blades, facilitate the more stable placement of the fan head 1 and motor base 2, ensuring the stability of the fan 100's position.

[0124] In some embodiments, the fan head 1 is adapted to be connected to the motor base 2 along a first direction in its initial position, the first direction intersecting the vertical direction. That is, when the fan head 1 is in its initial position relative to the motor base 2, the fan head 1 can be moved relative to the motor base 2 along the first direction, thereby connecting and fixing the fan head 1 to the motor base 2. For example, if the first direction is horizontal, the fan head 1 can be installed horizontally from front to back at the front end of the motor base 2, realizing the connection and fixation of the two in the horizontal direction.

[0125] The first direction can also form a certain tilt angle relative to the horizontal direction, and all of them intersect with the vertical direction. That is, the first direction can tilt upward or downward relative to the horizontal direction, making the installation of the fan head 1 more flexible.

[0126] The fan head 1 is designed to swing up and down and / or left and right relative to the motor base from its initial position. That is, after the fan head 1 is connected and fixed to the motor base 2, the user can adjust the angle of the fan head 1. If the fan head 1 and the motor base 2 are installed together on the base 4, the fan head 1 can be driven to adjust in different directions relative to the base 4, such as up, down, left and right. At this time, the fan head 1 can be adjusted so that its axis is parallel to the vertical direction, so that the adjustment range of the fan head 1 is larger and meets the user's air supply needs in more directions.

[0127] The present invention also proposes a method for assembling a fan.

[0128] The fan assembly method according to an embodiment of the present invention, such as... Figure 16 As shown, the assembly method is applicable to the fan 100 in any of the above embodiments and includes:

[0129] S1: Connect the fan head 1 to the motor base 2; that is, the fan head 1 and the motor base 2 are detachably connected, so that the fan head 1 can be disassembled independently relative to the motor base 2. This allows the fan head 1 to be removed independently for cleaning and replacement, reducing operating costs and maintaining good air quality output after cleaning. In actual connection, the fan head 1 and motor base 2 can be connected in multiple steps, or the fan head 1 can be directly connected to the motor base 2 as a whole.

[0130] S2: The child lock component 3 moves relative to the motor mount 2, locking the child lock component 3 and the fan head 1, simultaneously triggering the micro switch 23 to connect the power supply to the drive unit. Therefore, in actual use, when the user connects the motor mount 2 and the fan head 1, the child lock component 3 can be moved relative to the motor mount 2 to lock the motor mount 2 and the fan head 1, preventing the fan head 1 and motor mount 2 from automatically separating during fan 100 use. Simultaneously, the child lock component 3 pushes the micro switch 23 to activate the drive unit, thus enabling the drive of the fan blades 11. When the user disassembles the fan head 1, the child lock component 3 can be operated first to unlock the fan head 1 relative to the motor mount 2, facilitating the individual disassembly of the fan head 1. At the same time, the micro switch 23 is no longer subjected to the force of the child lock component 3 and resets, thereby disconnecting the power to the drive unit and stopping the fan blades 11 from rotating.

[0131] In other words, when the user disassembles the fan head 1 relative to the motor base 2, the child lock component 3 unlocks the fan head 1 relative to the motor base 2. At the same time, by acting on the micro switch 23, the drive component stops outputting driving force, so that the drive component is in a state of stopping power output during the disassembly of the fan head 1. This prevents the active action of the drive component from causing damage to the user when the user disassembles the fan head 1. Moreover, when the drive component drives the fan blade 11 to rotate, the fan head 1 and the motor base 2 are already in a stable connection state, which can provide better protection for children and improve the safety of using the fan 100.

[0132] In some embodiments, in the fan assembly method, driving the child lock component to move relative to the motor mount includes:

[0133] S21: The sliding paddle slides relative to the motor base, and during its movement, it pushes the locking pin to lock towards the fan head. The sliding paddle 31 is the driving component, and it is at least partially exposed outside the motor base 2, allowing the user to actively operate it. This allows the user to flexibly operate the sliding paddle 31 to drive the locking pin 33. The locking pin 33 is the driven component. When the sliding paddle 31 moves, the locking pin 33 moves relative to the motor base 2 under its influence. The locking pin 33 has a locked position and an unlocked position relative to the motor base 2. When the locking pin 33 is in the locked position, it can limit and fix the fan head 1 to lock it relative to the motor base 2, meaning the user cannot disassemble the fan head 1 relative to the motor base 2. When the locking pin 33 is in the unlocked position, the fan head 1 is unlocked relative to the motor base 2, allowing the user to flexibly disassemble the fan head 1.

[0134] Furthermore, in the specific construction, the motor base 2 can be rotatably screwed onto the fan head 1, allowing the fan head 1 to be rotatably mounted on the motor base 2. Simultaneously, a locking port 13 can be provided on the fan head 1. After the fan head 1 rotates to its position relative to the motor base 2, the locking pin 33 can extend into the locking port 13 and restrict the fan head 1 from rotating in the opposite direction relative to the motor base 2, preventing the fan head 1 from automatically rotating and disassembling relative to the motor base 2. During disassembly, the locking pin 33 can be extended from the locking port 13 via the sliding paddle 31. At this time, the locking pin 33 no longer has a circumferential limiting effect on the fan head 1, thus allowing the fan head 1 to be disassembled relative to the motor base 2. The structure is simple and facilitates flexible locking and unlocking of the fan head 1 and the motor base 2.

[0135] In some embodiments, in the fan assembly method, driving the child lock component to move relative to the motor mount further includes:

[0136] S22: During movement, the sliding paddle pushes the locking pin, triggering the micro switch to open and thus connecting the power supply to the drive component. It should be noted that the micro switch 23 is a normally open switch at this time; in other words, the micro switch 23 is in the open state when not subjected to external force. The locking pin 33 can contact the micro switch 23 during movement. Specifically, the design allows the sliding paddle 31 to simultaneously trigger the micro switch 23 to open when it locks the locking pin 33 against the fan head 1.

[0137] In other words, after the locking pin 33 locks the fan head 1, the locking pin 33 presses against the micro switch 23, so that the micro switch 23 is in the open state, the circuit of the driving component is in the connected state, and the driving component can output driving force at this time. After the locking pin 33 unlocks the fan head 1, the locking pin 33 removes the force on the micro switch 23, the micro switch 23 switches to the open state, the circuit of the driving component is disconnected, and the driving component does not output driving force at this time, thus realizing the safe disassembly of the fan head 1. Therefore, by setting the micro switch 23 and the locking pin 33 to cooperate, the structure is simple, and the locking state of the fan head 1 can be linked with the power state of the driving component, which is convenient to operate and highly safe.

[0138] Or S23: During the movement of the sliding paddle, the switch block is driven to release the pressure spring of the micro switch, so that the power supply to the driving component is turned on. It should be noted that at this time, the micro switch 23 is constructed as a normally open switch and is provided with a pressure spring 231. The pressure spring 231 is located on one side of the micro switch 23. One end of the pressure spring 231 is connected to the micro switch 23 and the other end is spaced apart from the micro switch 23. When the pressure spring 231 is in the naturally extended state, the micro switch 23 is in the connected state, so that the driving component can output driving force. When the pressure spring 231 is subjected to external force and deformed towards the micro switch 23, the micro switch 23 switches to the open state.

[0139] The child lock component 3 also includes a switch block 32. A sliding paddle 31 is connected to the switch block 32, and the sliding paddle 31 is adapted to drive the switch block 32 to press the abutment spring 231 when it drives the lock pin 33 to unlock from the fan head 1. That is, when the sliding paddle 31 moves relative to the motor base 2, it drives the lock pin 33 to unlock from the fan head 1. At the same time, the switch block 32 presses the abutment spring 231 of the micro switch 23, so that the abutment spring 231, after deformation, disconnects the micro switch 23, thereby cutting off the power output of the drive component and stopping the fan blade 11.

[0140] Similarly, when the sliding paddle 31 moves in the opposite direction, the sliding paddle 31 drives the locking pin 33 to lock with the fan head 1, and at the same time, it can drive the switch block 32 to activate the micro switch 23, thereby enabling the micro switch 23 to connect the power supply of the drive component, realize the power output of the drive component, and drive the fan blade 11 to rotate. The structure is simple and can realize the synchronous control of locking the motor base 2 and the fan head 1 as well as the driving force of the drive component, making it easy to operate.

[0141] In some embodiments, step S1, connecting the fan head to the motor mount, includes:

[0142] The drive component is installed in the motor housing to form a first independent body; for example, the motor housing includes a rear housing and a front cover plate, wherein the drive component can be configured as a drive motor, and the drive motor is installed in the rear housing. The front cover plate is connected to the front end of the rear housing, and the motor shaft passes through the front cover plate to realize the installation and fixation of the first independent body.

[0143] In addition, the fan blades are installed inside the fan head to form a second independent body; for example, the fan head includes a front mesh cover and a rear mesh cover, wherein the fan blades are installed between the front mesh cover and the rear mesh cover, and the front mesh cover and the rear mesh cover are then connected and stabilized. At the same time, the connecting shaft of the fan blades is inserted through the rear mesh cover to realize the installation and fixation of the second independent body.

[0144] Finally, the motor mount is connected to the fan head, and the drive unit is powered to the fan blades, so that the second independent body is integrally connected to the first independent body. In actual operation, the rear grille of the fan head can be screwed and fixed to the front cover of the motor mount. During the screwing process, the power coupling components on the connecting shaft and the motor shaft achieve power coupling. The installation process is simple and convenient, greatly reducing the connection steps between the fan head and the motor mount and improving installation efficiency.
