[0056] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0058] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0059] Reference below Figure 1-Figure 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 driving part of the fan 100 to avoid accidental triggering by children and improve the safety of the use of the fan 100.

[0060] like Figure 1-Figure 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 is provided with a fan blade 11, the motor base 2 is connected to the fan head 1, and a driving member is provided in the motor base 2. In actual design, the driving member can be set as a motor, the motor is used to output driving force, and the motor shaft of the motor can be connected to the fan head 1 for power, so that the motor drives the fan blade 11 to rotate. And the motor base 2 can be installed on a placement surface, or as Figure 1 and Figure 2As shown, a base 4 is provided below the motor base 2 so that the fan 100 can be installed on the placement surface through the base 4. The vertical height of the base 4 can be set to be relatively large, so that the motor base 2 and the fan head 1 are both at a relatively high position in the space, realizing airflow delivery to the user. The vertical height of the base 4 can also be set to be relatively small, so that the height of the motor base 2 and the fan head 1 is increased relative to the placement surface. Thus, the motor base 2 can be flexibly set to be directly placed on the placement surface to realize desktop placement, or even wall-mounted setting, or the overall height of the fan 100 can be flexibly adjusted through bases 4 of different heights, which is conducive to being applicable to different types of application scenarios and meeting different types of user needs, wherein the placement 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 independently removed relative to the motor base 2, thereby enabling the fan head 1 to be independently removed for cleaning and replacement, thereby helping to reduce the cost of use and maintaining good air quality output after cleaning.

[0063] After the motor base 2 and the fan head 1 are connected, the motor shaft is connected to the fan blades 11 by power. At this time, the fan blades 11 can be driven to rotate after the motor is started. In other words, the power connection between the driving member and the fan blades 11 can be achieved at the same time when the fan head 1 and the motor base 2 are connected. That is, after the motor base 2 and the fan head 1 are separated, the power connection between the driving member and the fan blades 11 is disconnected, thereby realizing the simultaneous installation and disassembly of the two groups of structures.

[0064] Among them, the motor base 2 is provided with a micro switch 23, and the micro switch 23 is used to control the power state of the driving member, that is, the opening or closing of the driving member can be controlled by controlling the micro switch 23. For example, the micro switch 23 can be set as a normally-off switch or a normally-on switch. The user can actively operate the micro switch 23 to flexibly switch the power state of the driving member, thereby flexibly selecting the driving state of the fan blade 11. It should be noted that the micro switch 23 can be used to directly start or shut down the driving member; the micro switch 23 can also be used to control the working circuit of the driving member. For example, when the micro switch 23 is disconnected, the working circuit cannot be connected or closed, and when the micro switch 23 is closed, the working circuit can be connected or closed, so as to flexibly switch the working state of the driving member and the fan blade 11.

[0065] The child lock component 3 can be movably mounted on the motor base 2 and is used to selectively lock with the fan head 1, and the child lock component 3 is also used to selectively trigger the micro switch 23 when it moves relative to the motor base 2, that is, the micro switch 23 can be driven to open or close by the action on the child lock component 3, thereby controlling the power output state of the drive member, that is, the user can drive the child lock component 3 to move relative to the motor base 2 in one direction so that the child lock component 3 can selectively trigger the micro switch 23, or can drive the child lock component 3 to move relative to the motor base 2 in another direction so that the child lock component 3 does not contact the micro switch 23 and thus chooses not to trigger the micro switch 23. It should be noted that the micro switch 23 can be built into the motor base 2 so that users, including children, cannot touch the micro switch 23, thereby avoiding safety problems caused by users directly touching the micro switch 23. The child lock component 3 can be used to achieve the connection locking between the motor base 2 and the fan head 1, and can also be used to trigger the micro switch 23 to achieve power control of the drive member.

[0066] Therefore, in actual use, the user connects the motor base 2 with the fan head 1. After the connection, the child lock component 3 can be driven to move relative to the motor base 2 so that the child lock component 3 locks the motor base 2 with the fan head 1, thereby preventing the fan head 1 and the motor base 2 from being automatically separated during the use of the fan 100. At the same time, the child lock component 3 pushes the micro switch 23 to operate, so that the drive member is turned on, thereby realizing the driving 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 base 2, so as to facilitate the separate disassembly of the fan head 1. At the same time, the micro switch 23 is no longer reset by the force of the child lock component 3, thereby disconnecting the power of the drive member and realizing the stopping of the rotation of the fan blades 11.

[0067] That is to say, 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, and at the same time, through the action of the micro switch 23, the driving component no longer outputs the driving force, so that the driving component is in a state of stopping outputting power during the disassembly of the fan head 1, thereby preventing the active action of the driving component from causing damage to the user when the user disassembles the fan head 1, and when the driving component drives the fan blades 11 to rotate, the fan head 1 and the motor base 2 are already in a stable connected state, which can provide better protection for child users and improve the safety of the use of the fan 100.

[0068] According to the fan 100 of the embodiment of the present invention, a child lock component 3 and a micro switch 23 are provided to cooperate so that when the user removes the fan head 1, the power of the driving component can be automatically cut off, and the driving component can be automatically connected after the fan head 1 and the motor base 2 are installed, thereby preventing the driving component and the rotating fan blades 11 from causing harm to the user and improving the safety of the use of the fan 100.

[0069] In some embodiments, the child lock component 3 includes a sliding paddle 31 and a locking pin 33. The sliding paddle 31 and the locking pin 33 can be movably installed on the motor base 2. The sliding paddle 31 and the locking pin 33 are slidably matched. The sliding paddle 31 is suitable for driving the locking pin 33 and the fan head 1 to selectively lock when it moves relative to the motor base 2.

[0070] That is to say, the sliding paddle 31 and the locking pin 33 can move respectively relative to the motor base 2, and the two can move relative to the motor base 2 in different directions, and the two use the direction of sliding cooperation to realize the driving of the locking pin 33 by the sliding paddle 31.

[0071] Among them, the sliding paddle 31 is an active part, and the sliding paddle 31 can be at least partially exposed outside the motor base 2, so that the user can actively operate the sliding paddle 31, so that the user can flexibly operate the sliding paddle 31 according to his own wishes to drive the locking pin 33. The locking pin 33 is a driven part. When the sliding paddle 31 moves, the locking pin 33 moves relative to the motor base 2 under the action of the sliding paddle 31, and the locking pin 33 has a locking position and an unlocking position relative to the motor base 2. When the locking pin 33 is in the locking position, the locking pin 33 can be limited and fixed with the fan head 1 to lock the fan head 1 relative to the motor base 2, that is, at this time, the user cannot disassemble the fan head 1 relative to the motor base 2, and when the locking pin 33 is in the unlocking position, the fan head 1 is unlocked relative to the motor base 2, and the user can flexibly disassemble the fan head 1.

[0072] Furthermore, in the specific structure, the motor base 2 can be rotatably engaged with the fan head 1, that is, the fan head 1 can be rotatably installed on the motor base 2, and a locking hole 13 can be provided on the fan head 1. After the fan head 1 is rotated into position relative to the motor base 2, the locking pin 33 can extend into the locking hole 13 and limit the reverse rotation of the fan head 1 relative to the motor base 2, thereby preventing the fan head 1 from automatically rotating and disassembling relative to the motor base 2. During disassembly, the locking pin 33 can be driven to extend from the locking hole 13 by the sliding paddle 31. At this time, the locking pin 33 no longer has a circumferential limiting effect on the fan head 1, thereby allowing the fan head 1 to be disassembled relative to the motor base 2. The structure is simple, which is conducive to the flexible locking and unlocking of the fan head 1 and the motor base 2.

[0073] In some embodiments, the sliding paddle 31 can slide along the circumference of the motor base 2, wherein a mounting slot extending along the circumference can be provided on the motor base 2, the sliding paddle 31 penetrates and is installed at the mounting slot, and the sliding paddle 31 can slide along the mounting slot relative to the motor base 2. 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] The locking pin 33 slides radially or vertically along the motor base 2, so that the locking pin 33 can move radially inward or outward relative to the motor base 2, so that the locking pin 33 moves to different positions. Among them, one of the sliding paddle 31 and the locking pin 33 is provided with a sliding guide groove 316 and the other is provided with a sliding guide rail 332, and the sliding paddle 31 and the locking pin 33 are slidably matched through the sliding guide rail 332 and the sliding guide groove 316. In other words, the sliding direction of the locking pin 33 and the motor base 2 can be flexibly set, and the locking pin 33 can preferably slide vertically relative to the motor base 2. In this way, when the locking pin 33 moves relative to the motor base 2, the locking pin 33 can slide down relative to the motor base 2 by gravity, which is conducive to improving the reliability of the downward movement of the locking pin 33.

[0075] Therefore, when the sliding paddle 31 moves relative to the motor base 2, the sliding guide rail 332 contacts the inner wall surface of the sliding guide groove 316 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 movement direction of the locking pin 33 along the motor base 2 can be along the radial direction of the motor base 2 or in the vertical direction, so as to increase the flexibility and limitations of the actual design. Fig.11 As shown, the movement direction of the locking pin 33 is along the up-down direction in the figure, and the up-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, the sliding guide groove 316 is provided in the sliding paddle 31, and a sliding guide surface 317 is formed in the sliding guide groove 316, and the sliding guide surface 317 is pressed against the locking pin 33. In other words, the sliding paddle 31 can be constructed as a hollow structure so that the sliding guide groove 316 is formed in the sliding paddle 31. Specifically, Fig.12 As shown, the sliding paddle 31 includes two inner walls that are opposite to each other, and each inner wall is provided with a sliding guide groove 316. Fig.13 As shown, a sliding guide rail 332 is provided on both sides of the outer end of the locking pin 33, so that during actual installation, the outer end of the locking pin 33 is extended into the sliding paddle 31 to achieve sliding cooperation between the two, and the two sets of sliding guide grooves 316 and the sliding guide rail 332 are cooperated to ensure the supporting stability of the locking pin 33, increase the contact area, and realize effective driving of the locking pin 33.

[0078] Among them, the distance between the sliding guide surface 317 and the axis of the motor seat 2 is set to gradually increase along the circumference of the motor seat 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 seat 2, the sliding guide surface 317 can use its own inclined and curved setting to push the locking pin 33 to move radially relative to the motor seat 2. Specifically, if the distance between the sliding guide surface 317 and the axis of the motor seat 2 is set to gradually increase along the clockwise direction of the motor seat 2, when the sliding paddle 31 slides in the clockwise direction relative to the motor seat 2, the sliding guide surface 317 pushes the locking pin 33 to move radially inwardly along the motor seat 2 to lock with the fan head 1; and when the sliding paddle 31 slides in the counterclockwise direction relative to the motor seat 2, the sliding guide surface 317 pushes the locking pin 33 to move radially outwardly along the motor seat 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, and the first limiting rib 311 and the second limiting rib 312 are formed with sliding guide surfaces 317 on the sides facing each other, 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 both push the locking pin 33 to move, thereby realizing the locking or unlocking of the locking pin 33 and the fan head 1.

[0080] like Fig.11 As shown, a first limiting rib 311 and a second limiting rib 312 are provided on the inner side wall of the sliding guide groove 316, and the first limiting rib 311 and the second limiting rib 312 are spaced apart along the radial direction of the motor base 2, as shown in FIG. Fig.11 As shown, the first limiting rib 311 is located on the outside of the second limiting rib 312, and the sliding guide surface 317 of the first limiting rib 311 and the sliding guide surface 317 of the second limiting rib 312 are relatively distributed, wherein when the sliding paddle 31 moves along the circumferential direction of the motor base 2, the locking pin 33 can be pushed from different directions by the two limiting ribs.

[0081] Specifically, Fig.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 to drive the locking pin 33 to move radially outward along the motor base 2, thereby unlocking the locking pin 33 and 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 to drive the locking pin 33 to move radially inward along the motor base 2, thereby locking the locking pin 33 and the fan head 1. Therefore, selective locking or unlocking with the fan head 1 can be achieved through the locking pin 33.

[0082] In some embodiments, the sliding paddle 31 is provided with a locking tooth surface 313, and the locking tooth surface 313 extends along the movement direction of the sliding paddle 31. The locking pin 33 is provided with an elastic member 34 and a pressing member 35. The elastic member 34 is connected between the locking pin 33 and the pressing member 35 and is used to press the pressing member 35 toward the locking tooth surface 313. In this way, the elastic force of the elastic member 34 can be used to keep the pressing member 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 member 35 can cooperate with the locking tooth surface 313 to produce a sense of jamming, thereby helping to enhance the user's rotation feel.

[0083] like Fig.11 As shown, the locking tooth surface 313 is disposed in 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, and the outer end of the pressing member 35 can extend into the sliding paddle 31 to abut against the locking tooth surface 313. Therefore, when the sliding paddle 31 slides along the circumference of the motor base 2, the outer end of the pressing member 35 can always press against the locking tooth surface 313, and the pressing member 35 can generate a sense of frustration with the tooth surface when switching to different tooth positions, thereby enhancing the user's hand feeling 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 315, the paddle cover 315 is connected to the paddle body 314, the paddle body 314 penetrates along the radial direction of the motor seat 2, and the paddle cover 315 is connected to the side of the paddle body 314 away from the motor seat 2, so that the side of the paddle body 314 away from the motor seat 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 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 the pressing member 35 in the locking pin 33 presses with the paddle cover 315, thereby effectively pushing the locking pin 33, and generating a significant sense of frustration, thereby improving the user experience.

[0085] In some embodiments, the locking tooth surface 313 extends along the circumference of 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 circumference 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 Fig.11As shown in , the sliding guide surface 317 is configured to gradually increase the distance from the axis of the motor seat 2 from left to right, and at the same time, the locking tooth surface 313 is also configured to gradually increase the distance from the axis of the motor seat 2 from left to right. It can be understood that when the locking pin 33 cooperates with the sliding guide groove 316, as the position of the sliding guide surface 317 changes, the locking pin 33 moves radially, and at the same time, the pressing member 35 at the locking pin 33 presses against the locking tooth surface 313 under the action of the elastic member 34. The locking tooth surface 313 and the sliding guide surface 317 are arranged in a conformal manner, so that the spacing between the locking pin 33 and the locking tooth surface 313 is always kept relatively uniform during radial movement, so that the elastic member 34 can always provide a relatively balanced elastic force to the pressing member 35, and then the pressing force between the pressing member 35 and the locking tooth surface 313 is relatively balanced, so as to maintain the frustration of the pressing member 35 at different positions and ensure the hand feeling of the user pushing the sliding paddle 31.

[0087] In some embodiments, the locking pin 33 is provided with a mounting groove 331, which is open radially outwardly along 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 the end of the elastic member 34 facing 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, thereby avoiding radial deformation of the elastic member 34 and causing it to be unable to provide effective elastic force.

[0088] Specifically, Fig.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 piece 35 is located in the mounting groove 331, the elastic piece 34 is located in the mounting groove 331, and the lower end of the elastic piece 34 is pressed against the inner bottom wall of the mounting groove 331, and the upper end of the elastic piece 34 is pressed against the pressing piece 35, so that the pressing piece 35 always maintains an upward pre-tightened state, and then extends to the outside of the mounting groove 331 to press and contact the locking tooth surface 313, wherein the elastic piece 34 will not bend radially when elastically deformed, and can stably apply an axial force to the pressing piece 35 to ensure the pressing pressure of the pressing piece 35 on the locking tooth surface 313.

[0089] In some embodiments, a conical pressing portion 351 is formed at the end of the pressing member 35, and the conical pressing portion 351 is suitable for pressing and cooperating with the locking tooth surface 313. Fig.11 As shown, the upper end of the pressing member 35 is constructed as a conical pressing portion 351, and the tip of the conical pressing portion 351 can be snapped into the tooth groove of the locking tooth surface 313, and as the sliding paddle 31 slides, the tip of the conical pressing portion 351 can be switched to different tooth grooves in turn, and the sudden switching of the tip at the crest and trough of the tooth groove can produce an obvious sense of frustration, thereby improving 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 may be sleeved outside the pressing member 35 and pressed 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] Among them, in actual construction, Fig.11 As shown, the pressing member 35 can be constructed with both ends symmetrical relative to the middle part, that is, the limiting ring 352 is arranged in the middle part of the length direction of the pressing member 35, and the upper and lower ends of the pressing member 35 are formed with conical pressing portions 351, the conical pressing portion 351 at the upper end is in pressing contact with the locking tooth surface 313, and the conical pressing portion 351 at the lower end is in pressing contact with the inner bottom wall of the mounting groove 331, the elastic member 34 is sleeved outside the lower end part of the pressing member 35, and the upper end of the elastic member 34 is pressed against the limiting ring 352, so that the pressing member 35 can also play a role in radial limiting the elastic member 34.

[0092] In some embodiments, the motor base 2 is provided with an outer plug-in ring 22, and the fan head 1 is provided with an inner plug-in ring 12, and the inner plug-in ring 12 is suitable for being plugged into the outer plug-in ring 22. Figure 2 As shown, the right end of the motor base 2 is provided with an outer plug-in ring 22, and the outer plug-in ring 22 protrudes axially at the right end of the motor base 2 to form a plug-in space in the outer plug-in ring 22. Figure 3 As shown, an inner plug-in ring 12 is provided at the left end of the fan head 1, and the inner plug-in ring 12 protrudes axially at the left end of the motor seat 2. The outer diameter of the inner plug-in ring 12 is smaller than the inner diameter of the outer plug-in ring 22, so that the inner plug-in ring 12 can be plugged into the outer plug-in ring 22 to achieve axial plug-in cooperation between the motor seat 2 and the fan head 1, and a clamping structure can be provided on the inner plug-in ring 12 and the outer plug-in ring 22, so that the two can be clamped by the clamping structure after plugging, so as to avoid automatic separation of the two and improve the structural stability.

[0093] Among them, the locking pin 33 is slidably installed on the outer plug-in ring 22, and the locking pin 33 is plugged and locked with the inner plug-in ring 12 radially inwardly along the outer plug-in ring 22 and unlocked with the inner plug-in ring 12 radially outwardly, so that a locking mouth 13 can be set on the inner plug-in ring 12, and after the inner plug-in ring 12 is plugged into the outer plug-in ring 22, the locking pin 33 can be moved radially inwardly along the outer plug-in ring 22 to make the inner end of the locking pin 33 plug into the locking mouth 13, thereby realizing the limit fixation of the outer plug-in ring 22 and the inner plug-in ring 12.

[0094] Specifically, the outer plug-in ring 22 and the inner plug-in ring 12 can be set to be rotationally plug-in, that is, after the inner plug-in ring 12 is set in the outer plug-in ring 22, it can be rotated relative to the outer plug-in ring 22 to rotate to the position where the locking mouth 13 and the locking pin 33 are directly opposite to each other along the radial direction of the outer plug-in ring 22. At this time, the locking pin 33 can be driven to move into the locking mouth 13 by the sliding paddle 31, so as to realize the plug-in limit of the locking pin 33 in the locking mouth 13, realize the locking of the fan head 1 and the motor base 2, prevent the fan head 1 from being automatically removed from the motor base 2, and improve the safety of the fan 100.

[0095] like Figure 3 As shown, a locking groove 121 is provided at the end of the inner plug-in ring 12, and a locking bevel 122 is provided in the locking groove 121. The locking bevel 122 can gradually press the outer plug-in ring 22 when the fan head 1 and the motor base 2 are rotationally connected, so as 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-off switch. In other words, the micro switch 23 is in an off state when no external force is applied. When the sliding paddle 31 moves relative to the motor base 2, it can press against the micro switch 23 to turn on the micro switch 23. Figure 7 As shown, at this time, the sliding paddle 31 is located at the right position, and there is no contact between the sliding paddle 31 and the micro switch 23, and the micro switch 23 is in the off state. At this time, the driving member has no power output. Further, as shown in FIG. 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, so that the micro switch 23 is turned on and the drive member can output power. Alternatively, the micro switch 23 is configured as a normally-on switch, in other words, the micro switch 23 is in the on state when it is not acted upon by an external force. When the sliding paddle 31 moves relative to the motor base 2, it can press against the micro switch 23 to turn off the micro switch 23, such as Figure 7 As shown, at this time, the sliding paddle 31 is located at the right position, and there is no contact between the sliding paddle 31 and the micro switch 23, and the micro switch 23 is in the on state. At this time, the driving member can output power. Further, as shown in FIG. Figure 8 As shown, the sliding paddle 31 moves to the left relative to the motor base 2 to gradually act on the micro switch 23 during the sliding process, so that the micro switch 23 is disconnected, thereby cutting off the power of the driving member.

[0097] In some embodiments, the micro switch is provided with a pressing spring piece 231, and the child lock component 3 is connected to a switch pressing block 32, the switch pressing block 32 and the pressing spring piece 231 are distributed along the circumference of the motor base 2, and the switch pressing block 32 is suitable for pressing or releasing the pressing spring piece 231 when the child lock component 3 moves relative to the motor base 2. Therefore, when the child lock component 3 slides relative to the motor base 2, the switch pressing block 32 moves relative to the motor base 2 along with the child lock component 3, and then gradually presses or releases the pressing spring piece 231 during the movement process, thereby switching the working state of the micro switch 23.

[0098] Specifically, the sliding paddle 31 is connected to the switch pressing block 32, and the sliding paddle 31 is suitable for driving the switch pressing block 32 to press the pressing spring piece 231 when driving the locking pin 33 to unlock the fan head 1. If the micro switch 31 is constructed as a normally-on switch, when the sliding paddle 31 moves relative to the motor base 2, the locking pin 33 is driven to unlock the fan head 1, and at the same time, the switch pressing block 32 presses the pressing spring piece 231 of the micro switch 23, so that the pressing spring piece 231 disconnects the micro switch 23 after deformation, thereby cutting off the power output of the driving member, and realizing the stopping of 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 can also drive the switch pressing block 32 to actuate the microswitch 23, so that the microswitch 23 connects the power supply of the driving component, realizes the power output of the driving component, and drives the fan blades 11 to rotate. The structure is simple, and can realize the locking of the motor base 2 and the fan head 1 and the synchronous control of the driving force of the driving component, and the operation is convenient.

[0100] In some embodiments, the sliding paddle 31 is slidable along the circumference of the motor base 2, and the switch pressing block 32 is connected to the inner side of the sliding paddle 31. Figure 4-Figure 5 , Figure 7-Figure 8 As shown, the switch pressing block 32 is located in the outer plug-in ring 22 of the motor base 2, and the sliding paddle 31 is located outside the outer plug-in ring 22. The switch pressing block 32 passes through the outer plug-in ring 22 to be connected to the inner side of the sliding paddle 31. The switch pressing 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 pressing block 32 to move in the outer plug-in ring 22.

[0101] Among them, the switch pressing block 32 and the pressing spring piece 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 pressing block 32 also moves along the circumference of the motor base 2, and the pressing spring piece 231 is located on the movement trajectory of the switch pressing block 32, so that the switch pressing block 32 can achieve contact and separation with the pressing spring piece 231 as the sliding paddle 31 moves, thereby achieving effective control of the micro switch 23, and then effectively controlling the power state of the driving member.

[0102] In some embodiments, the motor base 2 is provided with a pressing spring block 21, which is used to lock with the child lock component 3 when the child lock component 3 moves to the unlocked position, so that the child lock component 3 remains in a stable position when moving to the unlocked position, and prevents the child lock component 3 from automatically moving relative to the motor base 2. In this way, when the fan head 1 is installed and connected to the motor base 2 again, the position of the child lock component 3 is in an unlocked state, which is conducive to the re-installation of the motor base 2 and the fan head 1.

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

[0104] In some embodiments, the pressing spring block 21 is provided with an elastic column 211, and the elastic column 211 can be elastically retracted. The child lock component 3 is provided with a limiting opening. When the child lock component 3 moves to the unlocking position, the elastic column 211 extends into the limiting opening. Therefore, when the child lock component 3 is moved to the unlocking position, the elastic column 211 and the limiting opening can be limited to cooperate with each other to achieve relative fixation of the two, thereby achieving position locking of the child lock component 3.

[0105] Specifically, during actual installation, a spring may be provided on the elastic column 211, and a mounting hole may be provided in the pressing spring block 21, so that one end of the elastic column 211 is elastically connected to the mounting hole through the spring, and the end of the elastic column 211 elastically extends out from the surface of the pressing spring block 21. When the child lock component 3 is moved toward the elastic column 211, the child lock component 3 pushes the elastic column 211 to contract, and when the elastic column 211 is directly opposite to the limiting opening, the elastic column 211 elastically extends into the limiting opening to achieve position locking of the child lock component 3, and when the user needs to lock the motor seat 2 and the fan head 1 through the child lock component 3, the child lock component 3 may be pushed to move relative to the motor seat 2, so that the pressing spring block 21 presses against the elastic column 211 and overcomes the elastic force of the spring, so that the elastic column 211 contracts, and the child lock component 3 is unlocked relative to the pressing spring block 21, and the structure is simple.

[0106] In some embodiments, the motor base 2 is provided with a first limit portion and a second limit portion, and the child lock component 3 is provided with a first clamping portion and a second clamping portion. The first limit portion is used to clamp and limit with the first clamping portion in the unlocked position, and the second limit portion is used to clamp and limit with the second clamping portion in the closed position, so that the first limit portion and the second limit portion are respectively clamped and limited when the child lock component 3 moves to 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 unlocking position, the first limiting portion and the first clamping portion are clamped together to limit the movement of the child lock component 3 relative to the motor base 2. At this time, the locking pin 33 and the switch pressing block 32 are both stable in position relative to the motor base 2, which is convenient for the user to connect and fix the fan head 1 and the motor base 2 at any time without the problem of mismatching the installation position; and when the child lock component 3 is in the locking position, the second limiting portion and the second clamping portion are clamped together to limit 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 at the same time, the contact state of the switch pressing block 32 and the micro switch 23 is stable, and the problem of separation of the fan head 1 and the motor base 2 and interruption of the power of the driving part will not occur, thereby improving the safety and reliability of the structural design.

[0108] In some embodiments, the first limiting portion is constructed as a limiting protrusion 221, and the first clamping portion is constructed as a first hook 321. The first hook 321 is formed with a hook groove. The first hook 321 is clamped together with the limiting protrusion 221 and the limiting protrusion 221 is clamped into the hook groove, so that the child lock component 3 and the motor base 2 are relatively fixed 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, Figure 7 As shown, a protruding limit protrusion 221 is provided in the outer plug-in ring 22 of the motor base 2. The limit protrusion 221 protrudes inwardly along the radial direction of the motor base 2. Figure 7 As shown, a first hook 321 is provided on the switch pressing block 32 of the child lock component 3. The first hook 321 is located at the left end of the switch pressing block 32. The first hook 321 is formed with a hook groove that opens radially outward. When the child lock component 3 moves toward the unlocking position, Figure 7 When the child lock component 3 moves toward the left, the first hook 321 moves toward the left to a position opposite to the limiting protrusion 221, so that the first hook 321 is engaged in the hook groove, so that the child lock component 3 is stably maintained at the left position, thereby locking the child lock component 3.

[0110] And / or, the second limiting portion is constructed as a limiting block 222, and the second clamping portion is constructed as a second hook 322. The second hook 322 is clamped and limited with the limiting block 222, so that the child lock component 3 and the motor base 2 are relatively fixed in the locked 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 stopper 222 is provided in the outer plug-in ring 22 of the motor base 2. The stopper 222 and the stopper protrusion 221 are spaced apart and distributed in the circumferential direction of the outer plug-in ring 22. The stopper 222 protrudes inwardly along the radial direction of the motor base 2. Figure 7 As shown, a second hook 322 is provided on the switch pressing block 32 of the child lock component 3. The second hook 322 is located at the right end of the switch pressing block 32. When the child lock component 3 moves toward the unlocking position, as shown in FIG. Figure 8 When the child lock component 3 moves toward the right, the second hook 322 moves toward the right to a position opposite to 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 maintained in the right position, thereby achieving the locking of the child lock component 3. At this time, the locking pin 33 and the fan head 1 can be stably locked to ensure the installation stability of the fan head 1 on the motor base 2.

[0112] It should be noted that, in actual design, the limit block 222 can be constructed to cooperate with the locking pin 33, such as installing the locking pin 33 in the limit block 222, so that the limit block 222 can cooperate with both the locking pin 33 and the second hook 322, thereby simplifying the structural design.

[0113] In some embodiments, an outer plug-in ring 22 is formed at the end of the motor base 2, and an inner plug-in ring 12 is formed at the fan head 1, and the inner plug-in ring 12 is plugged into the outer plug-in ring 22; Figure 2 As shown, the right end of the motor base 2 is provided with an outer plug-in ring 22, and the outer plug-in ring 22 protrudes axially at the right end of the motor base 2 to form a plug-in space in the outer plug-in ring 22. Figure 3 As shown, an inner plug-in ring 12 is provided at the left end of the fan head 1, and the inner plug-in ring 12 protrudes axially at the left end of the motor seat 2. The outer diameter of the inner plug-in ring 12 is smaller than the inner diameter of the outer plug-in ring 22, so that the inner plug-in ring 12 can be plugged into the outer plug-in ring 22 to achieve axial plug-in cooperation between the motor seat 2 and the fan head 1, and a clamping structure can be provided on the inner plug-in ring 12 and the outer plug-in ring 22, so that the two can be clamped by the clamping structure after plugging, so as to avoid automatic separation of the two and improve the structural stability.

[0114] The first clamping portion and the second clamping portion both extend into the outer plug-in ring 22, and the first limiting portion and the second limiting portion are both arranged on the inner circumferential wall of the plug-in space, thereby, the first clamping portion and the first limiting portion are for clamping and limiting in the plug-in space, and the second clamping portion and the second limiting portion are also for clamping and limiting in the plug-in space, so that the limiting cooperation between the child lock component 3 and the motor seat 2 is a built-in structure, avoiding the problem of easy failure of the clamping due to the exposure of the clamping structure, and improving the reliability of the child lock component 3.

[0115] In some embodiments, the fan 100 also includes a base 4, which is suitable for being supported on a placement surface, and the motor base 2 is installed on the base 4, wherein the vertical height of the base 4 is greater than the vertical height of the motor base 2, so that the motor base 2 and the fan head 1 are both located at a higher position, which is beneficial for the wind blown out of the fan head 1 to act on the user more efficiently, thereby 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, and the support plate 41 has a large support area so 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. When the fan 100 is in working or not working state, the base 4 is supported on the placement surface, which can make the fan 100 more stably placed. The fan 100 can be supported on the placement surface by the base 4, that is, the fan 100 can be placed on the ground. This floor fan is conducive to the overall stable placement of the fan 100.

[0117] Among them, 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 demand for wind force in different directions of the fan 100 and improving the user experience.

[0118] In some embodiments, the fan head 1 as a whole is independently removable relative to the motor base 2, so that the fan head 1 can be completely independently removed from the motor base 2. In this way, when the user cleans the fan 100, the fan head 1 can be cleaned independently, which not only helps to improve the cleaning efficiency, but also facilitates the user to increase the cleaning frequency, ensuring that the fan 100 can always blow out fresh and clean wind, thereby improving the user experience.

[0119] Among them, it is also necessary to explain that in actual design, the fan head 1 and its internal fan blades and other structural parts can be regarded as a whole. At the same time, the motor base 2 and its internal motor and other structural parts can be regarded as a whole. When the fan head 1 and the motor base 2 are disassembled and installed as a whole, the mesh cover body of the fan head 1 and the shell of the motor base 2 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. At the same time, after the fan head 1 is disassembled from the motor base 2 as an independent body, the user can clean the fan head 1 as a whole, or disassemble and clean the internal structural parts of the fan head 1 to meet 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 configured as an axial flow fan blade, which is suitable for driving the airflow in the fan head 1 to flow toward the air outlet along the axial direction of the axial flow fan blade. In other words, the fan blades of the fan 100 of the present invention are different from traditional centrifugal fan blades, and can realize axial air intake and axial air outlet, wherein, during actual operation, the axial flow fan blades rotate, and drive the airflow at the rear side of the axial flow fan blades to flow forward along the axial direction thereof, and then flow to the air outlet at the front of the fan head 1 and transport toward the user's face.

[0121] Among them, it should be noted that the fan head 1 can be provided with an air inlet, and the air inlet can be provided on the rear side of the fan head 1 for axial air inlet, or can be provided on the circumferential outer side of the fan head 1 for oblique air inlet, both of which can realize the air inlet function of the fan head 1, and the airflow entering the fan head 1 can flow to the axial rear end of the axial flow fan blade, and then flow forward axially to the air outlet under the action of the axial flow fan blade. In particular, an air inlet can be provided on the rear side of the fan head 1, and a heat dissipation channel is provided in the motor base 2, so that the heat dissipation channel is connected with the air inlet, and then under the driving action of the axial flow fan blade, the airflow is driven to dissipate the heat for the driving parts and the like in the heat dissipation flow, and then flows from the air inlet to the user, which is not only beneficial to air supply, but also can realize the 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 driving member, and / or the ratio of the radial dimension of the fan head 1 to the axial dimension is greater than or equal to 1. Therefore, the fan in the present invention is different from the traditional crossflow impeller. It should be noted that the traditional tower fan uses a crossflow impeller, and the radial dimension of the tower fan at various axial positions does not change significantly, while the radial dimension of the fan head 1 in the present invention is much larger than the radial dimension of the motor base 2 at the driving member.

[0123] At the same time, compared with centrifugal fan blades, the provision of axial flow fan blades is conducive to more stable placement of the fan head 1 and the motor base 2, thereby ensuring the stability of the position state of the fan 100.

[0124] In some embodiments, the fan head 1 is adapted to be connected to the motor base 2 along a first direction in the initial position, and the first direction intersects with the vertical direction. That is, when the fan head 1 is in the 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, so that the fan head 1 is connected and fixed to the motor base 2. If the first direction is along the horizontal direction, the fan head 1 can be installed at the front end of the motor base 2 from front to back along the horizontal direction, so that the two are connected and fixed in the horizontal direction.

[0125] The first direction may also form a certain inclination angle relative to the horizontal direction and intersect with the vertical direction, that is, the first direction may be inclined upward or downward relative to the horizontal direction, so that the installation of the fan head 1 is more flexible.

[0126] The fan head 1 is configured to be able to swing up and down and / or left and right relative to the motor base from an 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. For example, the fan head 1 and the motor base 2 are installed together on the base 4, and the fan head 1 can be driven to adjust in different directions such as up, down, left and right relative to the base 4. At this time, the fan head 1 can be adjusted until its axis is parallel to the vertical direction, so that the adjustment range of the fan head 1 is larger, thereby meeting the user's air supply needs in more directions.

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

[0128] According to the fan assembly method of the embodiment of the present invention, Fig.16 As shown, the assembly method is applicable to the fan 100 of 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 independently disassembled relative to the motor base 2, so that the fan head 1 can be independently removed for cleaning and replacement, which is conducive to reducing the use cost and can maintain good air quality output after cleaning. Among them, when the fan head 1 and the motor base 2 are actually connected, they 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: drive the child lock component 3 to move relative to the motor base 2, and lock the child lock component 3 with the fan head 1, and trigger the micro switch 23 to turn on the power of the driving member. Therefore, in actual use, the user connects the motor base 2 with the fan head 1. After the connection, the child lock component 3 can be driven to move relative to the motor base 2 so that the child lock component 3 locks the motor base 2 with the fan head 1, thereby preventing the fan head 1 and the motor base 2 from being automatically separated during the use of the fan 100. At the same time, the child lock component 3 pushes the micro switch 23 to operate, so that the driving member is turned on, thereby realizing the driving 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 base 2, so as to facilitate the separate disassembly of the fan head 1. At the same time, the micro switch 23 is no longer reset by the force of the child lock component 3, thereby disconnecting the power of the driving member and realizing the stopping of the rotation of the fan blades 11.

[0131] That is to say, 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, and at the same time, through the action of the micro switch 23, the driving component no longer outputs the driving force, so that the driving component is in a state of stopping outputting power during the disassembly of the fan head 1, thereby preventing the active action of the driving component from causing damage to the user when the user disassembles the fan head 1, and when the driving component drives the fan blades 11 to rotate, the fan head 1 and the motor base 2 are already in a stable connected state, which can provide better protection for child users and improve the safety of the use of the fan 100.

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

[0133] S21: driving the sliding paddle to slide relative to the motor seat, and the sliding paddle pushes the locking pin to lock toward the fan head during the movement. The sliding paddle 31 is an active member, and the sliding paddle 31 can be at least partially exposed outside the motor seat 2, so that the user can actively operate the sliding paddle 31, so that the user can flexibly operate the sliding paddle 31 according to his own will to drive the locking pin 33. The locking pin 33 is a driven member. When the sliding paddle 31 moves, the locking pin 33 moves relative to the motor seat 2 under the action of the sliding paddle 31, and the locking pin 33 has a locking position and an unlocking position relative to the motor seat 2. When the locking pin 33 is in the locking position, the locking pin 33 can be limited and fixed with the fan head 1 to lock the fan head 1 relative to the motor seat 2, that is, at this time, the user cannot disassemble the fan head 1 relative to the motor seat 2, and when the locking pin 33 is in the unlocking position, the fan head 1 is unlocked relative to the motor seat 2, and the user can flexibly disassemble the fan head 1.

[0134] Furthermore, in the specific structure, the motor base 2 can be rotatably engaged with the fan head 1, that is, the fan head 1 can be rotatably installed on the motor base 2, and a locking hole 13 can be provided on the fan head 1. After the fan head 1 is rotated into position relative to the motor base 2, the locking pin 33 can extend into the locking hole 13 and limit the reverse rotation of the fan head 1 relative to the motor base 2, thereby preventing the fan head 1 from automatically rotating and disassembling relative to the motor base 2. During disassembly, the locking pin 33 can be driven to extend from the locking hole 13 by the sliding paddle 31. At this time, the locking pin 33 no longer has a circumferential limiting effect on the fan head 1, thereby allowing the fan head 1 to be disassembled relative to the motor base 2. The structure is simple, which is conducive to the 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 base further includes:

[0136] S22: The sliding paddle pushes the locking pin to trigger the micro switch to turn on during the movement, so that the power supply of the driving part is turned on. It should be noted that at this time, the micro switch 23 is constructed as a normally-off switch. In other words, the micro switch 23 is in an off state when it is not subjected to external force. Among them, the locking pin 33 can contact the micro switch 23 during the movement. In particular, when designing, the sliding paddle 31 can simultaneously drive the locking pin 33 to trigger the micro switch 23 to turn on when driving the locking pin 33 to lock with the fan head 1.

[0137] That is to say, after the locking pin 33 is locked with the fan head 1, the locking pin 33 presses against the micro switch 23, so that the micro switch 23 is in the on state, and the circuit of the driving member is in the on state, and the driving member can output the driving force. After the locking pin 33 is unlocked with the fan head 1, the locking pin 33 removes the force acting on the micro switch 23, the micro switch 23 is switched to the off state, and the circuit of the driving member is disconnected. At this time, the driving member does not output the driving force, so that the fan head 1 can be safely disassembled. Therefore, by setting the micro switch 23 to cooperate with the locking pin 33, the structure is simple, and the locking state of the fan head 1 can be linked with the power state of the driving member, which is easy to operate and has high safety.

[0138] Or S23: The sliding paddle drives the switch pressing block to release the pressing spring of the micro switch during the movement, so that the power supply of the driving part is turned on. It should be noted that at this time, the micro switch 23 is constructed as a normally-on switch and is provided with a pressing spring 231, wherein the pressing spring 231 is located on one side of the micro switch 23, one end of the pressing spring 231 is connected to the micro switch 23 and the other end is separated from the micro switch 23, wherein when the pressing spring 231 is in a naturally extended state, the micro switch 23 is in a connected state, that is, the driving part can output a driving force, and when the pressing spring 231 is squeezed and deformed toward the micro switch 23 by an external force, the micro switch 23 is switched to a disconnected state.

[0139] The child lock component 3 further includes a switch pressing block 32, and the sliding paddle 31 is connected to the switch pressing block 32, and the sliding paddle 31 is suitable for driving the switch pressing block 32 to press the pressing spring piece 231 when driving the locking pin 33 to unlock the fan head 1. In other words, when the sliding paddle 31 moves relative to the motor base 2, the locking pin 33 is driven to unlock the fan head 1, and at the same time, the switch pressing block 32 presses the pressing spring piece 231 of the micro switch 23, so that the pressing spring piece 231 disconnects the micro switch 23 after deformation, thereby cutting off the power output of the driving member, and realizing the stopping of 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 can also drive the switch pressing block 32 to actuate the microswitch 23, so that the microswitch 23 connects the power supply of the driving component, realizes the power output of the driving component, and drives the fan blades 11 to rotate. The structure is simple, and can realize the locking of the motor base 2 and the fan head 1 and the synchronous control of the driving force of the driving component, and the operation is convenient.

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

[0142] The driving member is installed in the motor base to form a first independent body; if the motor base includes a rear shell and a front cover plate, the driving member can be constructed as a driving motor, and the driving motor is installed in the rear shell, and the front cover plate is connected to the front end of the rear shell. At the same time, the motor shaft is passed through the front cover plate to achieve the installation and fixation of the first independent body.

[0143] And, the fan blades are installed in the fan head to form a second independent body; if the fan head includes a front mesh cover and a rear mesh cover, 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 stably. At the same time, the connecting shaft of the fan blades is passed through the rear mesh cover to achieve the installation and fixation of the second independent body.

[0144] Finally, the motor base is connected to the fan head and the driving member is connected to the fan blade power, so that the second independent body is connected to the first independent body as a whole. In actual operation, the rear mesh cover of the fan head and the front cover of the motor base can be screwed together and fixed, and during the screwing process, the power coupling member on the connecting shaft and the power coupling member on the motor shaft are dynamically coupled, the installation process is simple, the operation is convenient, the steps of connecting the fan head and the motor base are greatly reduced, and the installation efficiency is improved.
