[0111] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0112] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. 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.

[0113] 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.

[0114] The following is for reference. Figures 1-49 According to an embodiment of the present invention, the fan 100 has a fan head 1 that can be independently detached from the motor base 2, so that the fan head 1 can be removed for independent cleaning, which is convenient and allows the fan 100 to blow out clean air, thereby improving the user experience.

[0115] like Figures 1-49 As shown, a fan 100 according to an embodiment of the present invention includes a motor mount 2 and a fan head 1.

[0116] The motor base 2 contains a drive component 241, which can be a motor used to output driving force. In actual design, the motor base 2 can be mounted on a placement surface, or a base 4 can be set below the motor base 2 for mounting on the placement surface. The placement surface can be the ground or a tabletop, etc. A support plate 41 can be set below the base 4. The support plate 41 has a large support area, which can ensure that the fan 100 is stably supported on the placement surface, improving the placement stability of the fan 100.

[0117] The fan head 1 contains rotatable fan blades 11. The fan head 1 is detachably connected to the motor base 2, and the fan blades 11 are detachably powered by the drive unit 241, which drives the fan blades 11 to rotate. In other words, the fan head 1 can be flexibly installed and removed from the motor base 2. When the fan 100 is working normally, the fan head 1 can be installed on the motor base 2. When the fan 100 needs to be cleaned and maintained, the fan head 1 can be removed from the motor base 2. Thus, the fan head 1 is independently detachable from the motor base 2, which facilitates the user to clean and maintain the removed fan head 1.

[0118] After the fan head 1 is installed and connected to the motor base 2, the motor is powered by the fan blades 11. At this time, the motor can drive the fan blades 11 to rotate, thereby delivering airflow into the indoor space. After the fan head 1 is disassembled and separated from the motor base 2, the motor and fan blades 11 are disconnected. At this time, the energized and non-energized parts of the fan 100 are relatively separated. The user can disassemble and clean the non-energized fan head 1. This not only makes disassembly convenient and facilitates cleaning, but also enables electricity-free cleaning, improving the safety of the cleaning process. Furthermore, the disassembled fan head 1 is completely de-energized and can be directly rinsed.

[0119] Therefore, by making the fan head 1 independently detachable, users can increase the frequency of cleaning the fan head 1. For example, users can regularly remove the fan head 1 for washing every week. With the increase in the number of cleanings, dust is less likely to accumulate inside the fan head 1, ensuring cleaner air is blown out. Moreover, the detached fan head 1 can be directly rinsed with a tap, which is very convenient. In contrast, current mesh-type fans 100 are generally cleaned less frequently because the fan blades 11 and mesh are inconvenient to disassemble. Over time, dirt and grime can accumulate inside the fan 100 and in the gaps of the mesh, making each cleaning time lengthy and resulting in a poor user experience. The design of the fan 100 in this invention effectively solves the problem of inconvenient cleaning.

[0120] According to the embodiment of the present invention, the fan 100 is configured such that the fan head 1 is detachable from the motor base 2, which facilitates the user to increase the frequency of cleaning the fan head 1. When the fan 100 is detached from the motor base 2, the fan blades 11 are also connected and separated from the drive component 241, which is beneficial for the user to clean the fan head 1 and the internal fan blades 11, ensuring that dust does not easily accumulate inside the fan head 1, ensuring that the blown air is cleaner, and the cleaning process of the fan head 1 is safer, which helps to improve the user experience.

[0121] In some embodiments, such as Figure 36 As shown, the fan head 1 is provided with an air outlet 172, and the fan blade 11 is constructed as an axial flow fan blade. The axial flow fan blade is adapted to drive the airflow inside the fan head 1 to flow along the axial direction of the axial flow fan blade towards the air outlet 172. That is to say, the fan blade 11 of the fan 100 in this invention is different from the traditional centrifugal fan blade 11, 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 172 at the front of the fan head 1 to be delivered towards the user's face.

[0122] It should be noted that, for example Figure 33 As shown, the fan head 1 can be provided with an air inlet 252. The air inlet 252 can be located on the rear side of the fan head 1 for axial air intake, or it can be located on the circumferential outer 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 172 under the action of the axial fan blade. In particular, the air inlet 252 can be provided on the rear side of the fan head 1. At the same time, a heat dissipation channel is provided in the motor base 2, so that the heat dissipation channel is connected to the air inlet 252. Then, under the driving action of the axial fan blade, the airflow is driven to dissipate heat on the drive component 241 and other components in the heat dissipation flow, and then flows to the user through the air inlet 252. This not only facilitates air delivery, but also realizes internal heat dissipation of the motor base 2.

[0123] 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 member 241, 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 100 of this invention differs from a conventional cross-flow impeller. It should be noted that conventional 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 member 241.

[0124] 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.

[0125] In some embodiments, the fan head 1 is adapted to be connected to the motor base 2 in an initial position along a first direction, the first direction being along the axial direction of the fan blade 11 and intersecting 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, thereby fixing the fan head 1 to the motor base 2. Figure 1 As shown, the first direction is horizontal, and the fan head 1 can be installed horizontally from front to back on the front end of the motor base 2 to achieve horizontal connection and fixation between the two.

[0126] 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.

[0127] The fan head 1 is designed to swing up and down and / or left and right relative to the motor base 2 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.

[0128] 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.

[0129] It should also be noted that, in the actual design, the fan head 1 and its internal components such as the fan blades 11 can be considered as a whole. At the same time, the motor base 2 and its internal components such as the motor can be considered as a whole. When the fan head 1 and the motor base 2 are disassembled and installed as a whole, the mesh cover 14 of the fan head 1 and the housing 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. 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 components of the fan head 1, thus meeting the user's cleaning needs.

[0130] In some embodiments, such as Figure 2 As shown, the fan 100 also includes a child lock component 3, which is movably mounted on the motor mount 2 and used to selectively lock with the fan head 1. 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 driven to move relative to the motor mount 2 to lock the motor mount 2 and the fan head 1, preventing the fan head 1 from automatically separating from the motor mount 2 during use.

[0131] 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, making it easy to disassemble the fan head 1 separately. Similarly, when the user installs the fan head 1 onto the motor base 2, the fan head 1 can be connected to the motor base 2 first, and then the child lock component 3 can be driven to move relative to the motor base 2, thereby locking the motor base 2 and the fan head 1 together, preventing the fan head 1 from automatically falling off the motor base 2, ensuring the stability of the fan head 1 installation, and improving the reliability of the fan 100 operation.

[0132] In some embodiments, such as Figures 4-10 As shown, 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 can be 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 moves relative to the motor base 2.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] 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.

[0138] 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.

[0139] In some embodiments, such as Figure 9 As shown, 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 presses 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, the sliding paddle 31 includes two relatively distributed inner walls, and each inner wall is provided with a sliding guide groove 316. At the same time, a sliding guide rail 332 is provided on both sides of the outer end of the locking pin 33. Thus, during actual installation, the outer end of the locking pin 33 extends into the sliding paddle 31, realizing the sliding engagement between the two. The cooperation of the two sets of sliding guide grooves 316 and sliding guide rails 332 helps to ensure the support stability of the locking pin 33 and increases the contact area, thereby achieving effective driving of the locking pin 33.

[0140] 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.

[0141] In some embodiments, such as Figure 9 As shown, 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.

[0142] Specifically, a first limiting rib 311 and a second limiting rib 312 are provided on the inner sidewall 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. 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 circumferentially along the motor base 2, the locking pin 33 can be pushed from different directions by the two limiting ribs respectively.

[0143] In some embodiments, such as Figure 6 , Figures 8-9 As shown, 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 a first elastic element 34 and a pressing element 35. The first 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 first 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.

[0144] The locking tooth surface 313 is located inside the sliding paddle 31, and is situated 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 circumferentially along the motor base 2, the outer end of the pressing member 35 can always press against the locking tooth surface 313. Furthermore, as the sliding paddle 31 is switched to different tooth positions, the pressing member 35 can produce a jerking sensation with the tooth surface, thereby enhancing the user's feel when pushing the sliding paddle 31.

[0145] It should be noted that, as Figure 10 As shown, 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.

[0146] 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.

[0147] In some embodiments, such as Figure 6 As shown, 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 first elastic member 34 are installed in the mounting groove 331, and the end of the first 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 first elastic member 34 always maintain a stable radial position in the mounting groove 331, and avoid the first elastic member 34 from deforming radially, which would prevent it from providing effective elastic force.

[0148] Specifically, 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. The first elastic member 34 is located inside the mounting groove 331, and the lower end of the first elastic member 34 presses against the inner bottom wall of the mounting groove 331. The upper end of the first 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 first 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.

[0149] In some embodiments, such as Figure 6 As shown, the end of the pressing member 35 is formed with a tapered pressing part 351. The tapered pressing part 351 is adapted to press against the locking tooth surface 313. If the upper end of the pressing member 35 is constructed as a tapered pressing part 351, and the tip of the tapered pressing part 351 can be engaged in the tooth groove of the locking tooth surface 313, and as the sliding paddle 31 slides, the tip of the tapered pressing part 351 can be switched to different tooth grooves in sequence. By using the abrupt switching of the tip at the peak and trough of the tooth groove, a distinct sense of abruptness is generated, which improves the user's feel.

[0150] And / or, such as Figure 6 As shown, a limiting ring 352 can be provided on the outer peripheral wall of the pressing member 35. One end of the first 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 first elastic member 34, and at the same time, it also ensures that the first elastic member 34 can apply a stable elastic force to the pressing member 35.

[0151] In actual construction, 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 and lower ends 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 first elastic member 34 is sleeved on the lower part of the pressing member 35, and the upper end of the first elastic member 34 presses against the limiting ring 352, so that the pressing member 35 can also play a radial limiting role for the first elastic member 34.

[0152] In some embodiments, such as Figures 4-8 As shown, the motor base 2 is equipped with a micro switch 23, which is used to control the power state of the drive component 241. This means that the drive component 241 can be turned on or off by controlling the micro switch 23. For example, 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 241, 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 stop the drive component 241; the micro switch 23 can also be used to control the working circuit of the drive component 241. 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 241 and the fan blade 11.

[0153] 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 unit 241. In other words, the user can move the child lock component 3 in one direction relative to the motor mount 2 to selectively trigger the micro switch 23, or move 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 it, avoiding safety issues caused by direct contact. The child lock component 3 can be used to lock the connection between the motor mount 2 and the fan head 1, and also to trigger the micro switch 23 to control the power output of the drive unit 241.

[0154] Therefore, by setting the child lock component 3 and the micro switch 23 in conjunction, the power of the drive component 241 can be automatically cut off when the user disassembles the fan head 1, and the drive component 241 can be automatically connected after the fan head 1 is installed with the motor base 2, thereby avoiding damage to the user caused by the drive component 241 and the rotating fan blades 11, and improving the safety of using the fan 100.

[0155] In some embodiments, the micro switch 23 is configured as a normally open switch, meaning that the micro switch 23 is in an open state when not subjected to external force. When the sliding paddle 31 moves relative to the motor base 2, it presses against the micro switch 23 to open and conduct the micro switch 23. At this time, the sliding paddle 31 is located on the right side, and there is no contact between the sliding paddle 31 and the micro switch 23, so the micro switch 23 is in an open state. At this time, the drive unit 241 has no power output. Further, 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, causing the micro switch 23 to open and conduct, thereby enabling the drive unit 241 to output power.

[0156] Alternatively, the micro switch 23 can be configured as a normally-on switch, meaning that the micro switch 23 is in a 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 disengage the micro switch 23. At this time, the sliding paddle 31 is in a right-hand position, and there is no contact between the sliding paddle 31 and the micro switch 23, so the micro switch 23 is in a conducting state. At this time, the drive unit 241 can output power. Furthermore, 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 disengage, thereby cutting off the power to the drive unit 241.

[0157] In some embodiments, such as Figure 6 and Figure 7 As shown, the micro switch 23 is equipped with a pressing spring 231, and the child lock component 3 is connected to a switch block 32. The switch block 32 and the pressing spring 231 are distributed circumferentially along the motor base 2, and the switch 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 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.

[0158] 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 23 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 241 and stopping the fan blade 11.

[0159] Similarly, when the sliding paddle 31 moves in the opposite direction, it locks the locking pin 33 to the fan head 1, and at the same time, it drives the switch block 32 to activate the micro switch 23. This causes the micro switch 23 to connect the power supply to the drive unit 241, thereby enabling the drive unit 241 to output power 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 unit 241, making it easy to operate.

[0160] In some embodiments, such as Figure 4 As shown, the motor base 2 is provided with a pressing spring block 21. The pressing spring block 21 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.

[0161] The motor base 2 is provided with a pressing spring block 21, which is located in the direction of movement of the child lock component 3. When the sliding paddle 31 moves, it can drive the switch pressing block 32 to rotate around the axis of the motor base 2, and then gradually press against the pressing spring block 21 during the rotation. The limiting structure on the pressing spring block 21 can then achieve limiting and fixing, thereby locking the position of the child lock component 3.

[0162] In some embodiments, such as Figure 7 As shown, the pressing 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.

[0163] Specifically, during actual installation, a spring can be installed on the elastic post 211, and a fixing hole is provided in the pressing block 21 so that one end of the elastic post 211 is elastically connected to the fixing hole through the spring, and the end of the elastic post 211 elastically extends out of the surface of the pressing 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 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 block 21. The structure is simple.

[0164] 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.

[0165] 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 power interruption of the drive component 241, thus improving the safety and reliability of the structural design.

[0166] In some embodiments, such as Figure 2 and Figure 3As shown, one of the motor base 2 and the fan head 1 is provided with an external insertion ring 22 and the other is provided with an internal insertion ring 12. The internal insertion ring 12 is inserted into the external insertion ring 22. For example, the motor base 2 is provided with an external insertion ring 22 and the fan head 1 is provided with an internal insertion ring 12. The internal insertion ring 12 is adapted to be inserted into the external insertion ring 22. For example, the motor base 2 is provided with an external insertion ring 22 at the end facing the fan head 1. The external insertion ring 22 protrudes axially at the right end of the motor base 2 to form an insertion space in the external insertion ring 22. At the same time, the fan head 1 is provided with an internal insertion ring 12 at the end facing the motor base 2. The internal insertion ring 12 protrudes axially at the 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 and engagement 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 so that the two can be snapped together after insertion, preventing them from automatically disengaging and improving structural stability.

[0167] The inner insertion ring 12 has a locking groove 121 at its end, and a locking slope 122 is provided in the locking groove 121. The locking slope 122 can gradually press the outer insertion ring 22 when the fan head 1 and the motor base 22 are rotated together, so as to achieve a tight connection between the fan head 1 and the motor base 22.

[0168] In some embodiments, such as Figure 6 As shown, 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 forms a hook groove. The first hook 321 engages with the limiting protrusion 221 and the limiting protrusion 221 engages into the hook groove, thereby making the child lock component 3 and the motor base 2 relatively fixed in the unlocked position, ensuring that the motor base 2 can quickly and efficiently achieve connection and fixation when connected to the fan head 1.

[0169] The motor base 2 has a protruding limiting protrusion 221 inside the outer insertion ring 22. The limiting protrusion 221 protrudes inward along the radial direction of the motor base 2. At the same time, the child lock component 3 has a first hook 321 on the switch pressure block 32. If the first hook 321 is located at the left end of the switch pressure block 32, the first hook 321 forms a hook groove that opens outward along the radial direction. When the child lock component 3 moves to the left unlock position, the first hook 321 moves to the 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 achieving the locking of the child lock component 3.

[0170] 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.

[0171] The motor base 2 has a protruding limiting block 222 inside the outer insertion ring 22. 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. At the same time, the child lock component 3 has a second hook 322 on the switch pressure block 32. If 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, such as moving to the right, the second hook 322 moves to the right to the position directly opposite the limiting block 222, so that the second hook 322 and the limiting block 222 are stably engaged, so that the child lock component 3 is stably kept 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.

[0172] 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.

[0173] In some embodiments, such as Figure 11 As shown, the fan head 1 also includes a mesh cover 14, and the fan blade 11 includes a connecting shaft 151 and a fan blade 152. The fan blade 152 is sleeved on the connecting shaft 151, and the connecting shaft 151 is rotatably supported on the mesh cover 14. The connecting shaft 151 is poweredly connected to the drive component 241. The mesh cover 14 has a hollow structure, and an installation cavity is formed inside the mesh cover 14. The fan blade 11 is rotatably installed in the installation cavity. The fan blade 152 can be circumferentially driven with the connecting shaft 151. At the same time, the connecting shaft 151 is poweredly connected to the drive component 241, so that when the drive component 241 outputs power, it can drive the connecting shaft 151 to rotate, thereby driving the fan blade 152 to rotate through the connecting shaft 151, realizing airflow delivery.

[0174] The mesh cover 14 has perforated holes, and multiple perforated holes can be provided. Some of the perforated holes can be provided on the rear side of the mesh cover 14 as air inlets 252, and other perforated holes can be provided on the front side of the mesh cover 14 as air outlets 172. This allows the fan blades 152 to drive airflow from the air inlets 252 into the mounting cavity during rotation, and then deliver it to the user's space from the air outlets 172.

[0175] In some embodiments, such as Figure 12 As shown, the mesh cover 14 includes a first mesh cover 141 and a second mesh cover 142, which are detachably connected. In other words, the first mesh cover 141 and the second mesh cover 142 can be detached relatively independently, and together define a mounting cavity after connection. The fan blade 11 is installed between the first mesh cover 141 and the second mesh cover 142, and the fan blade 11 is rotatably supported by the first mesh cover 141 and / or the second mesh cover 142, so that the fan blade 11 can rotate flexibly. The first mesh cover 141 is used to connect to the motor base 2, and the second mesh cover 142 is connected to the side of the first mesh cover 141 opposite to the motor base 2. The motor base 2 is located on the rear side of the fan head 1. In other words, the first mesh cover 141 can serve as the rear mesh cover, and the second mesh cover 142 can serve as the front mesh cover.

[0176] The second mesh cover 142 is constructed as a flat disc structure, and the diameter of the first mesh cover 141 is the same as the end diameter of the mesh cover body 14. The first mesh cover 141 is constructed as an arc-shaped bowl structure, creating an internal space for the fan blades 11 to rotate. The edge of the second mesh cover 142 is a mesh structure formed by multiple metal wires, ensuring that as much airflow as possible generated by the fan blades 11 during rotation reaches the air outlet formed in the second mesh cover 142, thereby improving the efficiency of the fan 100. Furthermore, the first and second mesh covers 141 and 142 prevent interference from people or other objects, thus avoiding personal injury and short circuits. In other words, the first and second mesh covers 141 and 142 serve to prevent foreign objects from touching the internal structure of the fan 100.

[0177] Furthermore, in some embodiments, such as Figure 11 and Figure 12 As shown, a first bearing 1412 is provided at one end of the connecting shaft 151, such that the rear end of the connecting shaft 151 is rotatably supported on the first mesh cover 141 via the first bearing 1412. A second bearing 1422 is provided at the other end of the connecting shaft 151, such that the front end of the connecting shaft 151 is rotatably supported on the second mesh cover 142 via the second bearing 1422. That is, the first bearing 1412 is provided on the first mesh cover 141, and the second bearing 1422 is provided at the end of the connecting shaft 151 away from the driving member 241, that is, the second bearing 1422 is provided on the second mesh cover 142, so that the front end of the connecting shaft 151 is rotatably supported on the second mesh cover 142 via the second bearing 1422, and the rear end of the connecting shaft 151 is rotatably supported on the first mesh cover 141 via the second bearing 1422.

[0178] Among them, such as Figure 11As shown, the first mesh cover 141 is provided with a first connecting hole 1411, and the first bearing 1412 is installed at the first connecting hole 1411, and the first mesh cover 141 and the first bearing 1412 are axially limited and fixed; and / or, the second mesh cover 142 is provided with a second connecting hole 1421, and the second bearing 1422 is installed at the second connecting hole 1421, and the second mesh cover 142 and the second bearing 1422 are axially limited and fixed, that is, the first mesh cover 141 is provided with a first connecting hole 1411, the first bearing 1412 is installed at the first connecting hole 1411, and the first mesh cover 141 and the first bearing 1412 are axially limited and fixed. Meanwhile, the second mesh cover 142 is provided with a second connecting hole 1421, and the second bearing 1422 is installed at the second connecting hole 1421. The second mesh cover 142 and the second bearing 1422 are axially limited and fixed. Alternatively, only the first mesh cover 141 is provided with a first connecting hole 1411, and the first bearing 1412 is installed at the first connecting hole 1411. The first mesh cover 141 and the first bearing 1412 are axially limited and fixed. Alternatively, only the second mesh cover 142 is provided with a second connecting hole 1421, and the second bearing 1422 is installed at the second connecting hole 1421. The second mesh cover 142 and the second bearing 1422 are axially limited and fixed.

[0179] Specifically, in this embodiment, the first mesh cover 141 is provided with a first connecting hole 1411, the radial size of which matches the radial size of the first bearing 1412, so that the first bearing 1412 is installed at the first connecting hole 1411, and the first mesh cover 141 and the first bearing 1412 are axially limited and fixed, thereby restricting the axial movement of the first bearing 1412 relative to the first mesh cover 141. Meanwhile, the second mesh cover 142 is provided with a second connecting hole 1421, the radial size of which matches the radial size of the second bearing 1412. The radial dimensions of 1422 are matched. The second bearing 1422 is installed at the second connecting hole 1421, and the second mesh cover 142 and the second bearing 1422 are axially limited and fixed, thereby restricting the axial movement of the second bearing 1422 relative to the second mesh cover 142. This allows the first bearing 1412 and the second bearing 1422 to be fixed to the mesh cover body 14, so that the connecting shaft 151 can be rotatably supported on the mesh cover body 14 through the first bearing 1412 and the second bearing 1422, and its own axis position can be adjusted to ensure transmission stability.

[0180] Among them, such as Figure 12 As shown, the second mesh cover 142 may be provided with a decorative panel 1423, which can cover the second connecting hole 1421 and the second bearing 1422, so that the connecting shaft 151 and the second bearing 1422 of the fan head 1 are not visible to the user from the front side of the second mesh cover 142, thus improving the user's viewing experience.

[0181] Alternatively, in some other embodiments, the connecting shaft 151 is rotatably supported on the mesh cover 14 by a bearing component. The bearing component can provide support for the connecting shaft 151, and a buffer structure is provided at the connection between the bearing component and the mesh cover 14, thereby reducing the vibration generated by the connecting shaft 151 when transmitting power and improving the smoothness of the operation of the fan 100.

[0182] During power transmission, the bearing component provides support to the connecting shaft 151. At the same time, when the fan blade 152 rotates, it will exert a force on the bearing component. This force can be transmitted to the buffer structure through the bearing component, thereby reducing the effect of the force on the fan head 1, making the fan 100 run more smoothly. In addition, the fan head 1 and the mesh cover 14 are detachably connected, making the installation and removal of the fan head 1 easier and more convenient.

[0183] In some embodiments, such as Figure 13 As shown, the bearing component is detachably installed on the mesh cover 14, and the buffer structure is constructed as a buffer pad 155, which is sandwiched between the bearing component and the mesh cover 14.

[0184] Specifically, the bearing component is located between the mesh cover 14 and the connecting shaft 151, and can be used to provide support for the connecting shaft 151. The bearing component needs to be maintained regularly during use. The bearing component can be detachably installed in the mesh cover 14 to save maintenance time. When the bearing component is damaged, only the bearing component can be replaced, saving costs.

[0185] Meanwhile, when the fan 100 is running, the rotation of the fan blade 152 will generate a force on the connecting shaft 151 connected to it. This force will then be transmitted to the bearing component through the connecting shaft 151. By setting the bearing component as an independent component, the transmission path of the force is increased, thereby weakening the effect. In addition, a buffer pad 155 is provided between the bearing component and the mesh cover 14. When the force is transmitted to the mesh cover 14 through the bearing component, it can be buffered by the buffer pad 155, further weakening the effect of the force and improving the smoothness of the fan 100 operation.

[0186] In some embodiments, the fan 100 further includes a pre-tightening structure, which is connected to the connecting shaft 151 and used to axially limit the connecting shaft 151. The pre-tightening structure can be connected to the end of the connecting shaft 151 and is used to control the axial clearance of the connecting shaft 151. This allows the connecting shaft 151 to have a dynamic clearance control function when rotating, ensuring that the connecting shaft 151 has a suitable clearance along the axial direction, thus preventing axial movement during internal rotation of the fan 100 and affecting the stability of the fan 100's operation.

[0187] Therefore, by setting a pre-tightening structure at the output end of the connecting shaft 151, the axial clearance of the connecting shaft 151 can be controlled. This facilitates the smooth rotation of the output end of the connecting shaft 151, thereby ensuring the smooth rotation of the fan blade 11. It can also prevent vibration and friction of the connecting shaft 151 along the axial direction, achieving noise reduction. This makes the power transmission between the drive component 241 and the connecting shaft 151 more efficient, enhances the functionality of the fan 100, improves the product's service life and user experience, and has a simple structure and strong applicability.

[0188] In some embodiments, such as Figure 14 and Figure 15 As shown, the pre-tightening structure is constructed as an elastic bearing component 156. The elastic bearing component 156 includes a bearing portion 1561 and an elastic portion 1562 connected together. The bearing portion 1561 is fixed axially relative to the fan head 1. The connecting shaft 151 is rotatably supported in the fan head 1 through the bearing portion 1561, and the elastic portion 1562 applies an elastic force toward the connecting shaft 151.

[0189] In other words, such as Figure 16 As shown, the elastic bearing component 156 includes two parts: a bearing part 1561 and an elastic part 1562. The bearing part 1561 is fixed relative to the fan head 1 along the axis, which can fix the bearing part 1561 and the elastic bearing component 156. The elastic bearing component 156 is constructed in a ring shape and is coaxially connected to the connecting shaft 151, which allows the connecting shaft 151 to be rotatably supported inside the fan head 1, thus enabling the connection of the connecting shaft 151. The connecting shaft 151 can rotate relative to the fan head 1, and the elastic part 1562 can apply an elastic force toward the connecting shaft 151 to adjust the axial clearance of the connecting shaft 151.

[0190] When the axial clearance of the connecting shaft 151 is too large, the elastic part 1562 of the pre-tightening structure will release and absorb the excess clearance, thereby applying an elastic force to the connecting shaft 151 toward the driving member 241, which can reduce the axial clearance of the connecting shaft 151. When the axial clearance of the connecting shaft 151 is small, the elastic part 1562 of the pre-tightening structure will be compressed by the connecting shaft 151, which can release a certain amount of axial clearance for the connecting shaft 151, thereby increasing the axial clearance of the connecting shaft 151. This can prevent the connecting shaft 151 from rotating too slowly due to the axial clearance being too small. In this way, the axial clearance of the connecting shaft 151 can be comprehensively adjusted by the elastic part 1562 to ensure that the axial clearance of the connecting shaft 151 is more stable.

[0191] Therefore, by making the above-mentioned configuration on the elastic bearing component 156, the connection between the elastic bearing component 156 and the connecting shaft 151 can be realized simultaneously, and the axial clearance of the connecting shaft 151 can be adjusted. Furthermore, the axial clearance of the connecting shaft 151 can be dynamically controlled, so that the connecting shaft 151 has a suitable clearance along the axial direction, thereby improving the stability of the fan 100 operation.

[0192] In some embodiments, such as Figure 17 and Figure 18 As shown, the pre-tightening structure is constructed as a sleeve 157, which is fixedly installed in the mesh cover body 14 along the axial direction, and the sleeve 157 is sleeved on the outside of the connecting shaft 151 and fixedly installed in the axial direction with the connecting shaft 151.

[0193] Specifically, the sleeve 157 is installed axially inside the fan head 1, and the sleeve 157 is installed near the output end of the connecting shaft 151. In actual design, the sleeve 157 can be constructed as a ring, and the sleeve 157 is sleeved on the outside of the connecting shaft 151. The two ends of the sleeve 157 are limited and fixed along the axial direction, which can realize the installation and fixation of the sleeve 157. The sleeve 157 can be of two forms: one can be constructed as rigid, which can ensure that the axial clearance of the connecting shaft 151 is a fixed value during the operation of the connecting shaft 151 and meet the axial clearance requirements of the connecting shaft 151; the other can be constructed as elastic, which can make the sleeve 157 compressible, and can ensure that the axial clearance of the connecting shaft 151 is controlled within a certain range during the operation of the connecting shaft 151, so as to realize the dynamic control of the axial clearance of the connecting shaft 151 to meet the axial clearance requirements of the connecting shaft 151.

[0194] Therefore, the pre-tightening structure is set as sleeve 157, which has a simple structure and low manufacturing cost. At the same time, the material of sleeve 157 can be either rigid or elastic, which makes the pre-tightening structure flexible and ensures that the axial clearance of connecting shaft 151 meets the requirements, so as to make the operation of connecting shaft 151 smooth.

[0195] In some embodiments, such as Figure 17 and Figure 18As shown, the fan head 1 is equipped with a bearing 158 and a blade nut 154. The blade nut 154 is axially connected to the fan blade 152. The end of the connecting shaft 151 is rotatably supported in the fan head 1 through the bearing nut 158. Thus, the fan blade 152 can be installed axially, and the end of the connecting shaft 151 can be fixed inside the fan head 1 through the bearing nut 158. In the axial direction of the connecting shaft 151, a sleeve 157 is sandwiched between the blade nut 154 and the bearing nut 158. Thus, the sleeve 157 can be installed and fixed, and a certain gap can be maintained between the blade nut 154 and the bearing nut 158, thereby adjusting the axial gap of the connecting shaft 151.

[0196] Specifically, the bearing component 158 ​​is sleeved on the output end of the connecting shaft 151, and the bearing component 158 ​​is connected to the inside of the fan head 1. The bearing component 158 ​​can be axially limited, allowing the connecting shaft 151 to be rotatably supported within the fan head 1. The fan blade 152 and fan blade nut 154 are positioned close to the drive component 241, with the fan blade 152 and fan blade nut 154 sleeved outside the connecting shaft 151. The fan blade nut 154 is positioned close to the bearing component 158. The nut 154 is axially limited and fixed to the fan blade 152, which enables the axial installation of the fan blade 152. A sleeve 157 is provided between the fan blade nut 154 and the bearing component 158. The sleeve 157 is sleeved outside the connecting shaft 151, which allows the sleeve 157 to axially limit the fan blade nut 154. The sleeve 157 presses against the fan blade nut 154 and the bearing component 158 ​​respectively, which is used to control the distance between the fan blade nut 154 and the bearing component 158.

[0197] In some embodiments, such as Figure 19 As shown, the drive unit 241 is connected to the first magnetic absorbing member 243, and the fan blade 11 is connected to the second magnetic absorbing member 161. After the motor base 2 is connected to the fan head 1, the drive unit 241 and the fan blade 11 are driven to connect under the magnetic field of the first magnetic absorbing member 243 and the second magnetic absorbing member 161.

[0198] The drive unit 241 outputs power outward. A first magnetic chuck 243 is connected to the power output end of the drive unit 241. A second magnetic chuck 161 is connected to the side of the fan blade 11 closest to the motor base 2. When the second magnetic chuck 161 and the first magnetic chuck 243 are close together, they generate a magnetic field, creating an attractive force that drives the output end of the drive unit 241 to connect with the fan blade 11. Alternatively, a repulsive force can be generated between the second magnetic chuck 161 and the first magnetic chuck 243, using the repulsive force to rotate the fan blade. The design is flexible and can be chosen flexibly. Thus, the drive unit 241 can transmit power to the second magnetic chuck 161 via the first magnetic chuck 243, and then transmit power to the fan blade 11 via the second magnetic chuck 161, causing the fan blade 11 to rotate. Furthermore, during disassembly, the first magnetic chuck 243 and the second magnetic chuck 161 can be directly separated, making disassembly more convenient and facilitating the disassembly and cleaning of the fan head 1.

[0199] Furthermore, the drive component 241 is configured as a drive motor, such as... Figure 20 As shown, the first magnetic suction member 243 is sleeved outside the output shaft 2411 of the drive motor and is in circumferential transmission cooperation with the output shaft 2411; the fan blade 11 is provided with a connecting shaft 151, which is rotatably installed inside the fan head 1, such as... Figure 21 As shown, the second magnetic suction member 161 is sleeved on the outside of the connecting shaft 151 and is in circumferential transmission cooperation with the connecting shaft 151.

[0200] Specifically, the driving component 241 can be configured as a drive motor. An output shaft 2411 is provided on the side of the drive motor near the fan head 1. A first magnetic chuck 243 is connected to the output shaft 2411. The first magnetic chuck 243 is sleeved outside the output shaft 2411 and is circumferentially fixed to the output shaft 2411, so that when the output shaft 2411 rotates to output power, the first magnetic chuck 243 can rotate together. A connecting shaft 151 is provided on the side of the fan head 1 near the drive motor. A second magnetic chuck 161 is connected to the connecting shaft 151. The second magnetic chuck 161 is sleeved outside the connecting shaft 151 and is circumferentially fixed to the connecting shaft 151. The connecting shaft 151 is relatively fixed, so that when the second magnetic attractor 161 rotates, the connecting shaft 151 can rotate together. The connecting shaft 151 can rotate relative to the fan head 1 and is fixedly connected to the fan blade 11, thereby causing the fan blade 11 to rotate. This generates a magnetic field between the first magnetic attractor 243 and the second magnetic attractor 161, thereby generating an attractive force. This completes the drive connection between the output shaft 2411 of the drive motor and the connecting shaft 151 of the fan blade 11. The output shaft 2411 of the drive motor drives the connecting shaft 151 of the fan blade 11 to rotate, thereby causing the fan blade 11 to rotate, and enabling the fan 100 to blow air.

[0201] In some embodiments, the fan head 1 is adapted to be connected to the motor base 2 along a first direction, which intersects with the vertical direction. A gap adjustment part 162 is provided at the connection between the fan head 1 and the motor base 2. The gap adjustment part 162 is used to reduce the top fitting gap at the connection after the fan head 1 and the motor base 2 are connected.

[0202] The fan head 1 is detachable from the motor base 2, which increases the frequency of cleaning the fan head 1 to ensure that the fan 100 blows out clean air and avoids secondary air pollution. When the fan head 1 is connected to the motor base 2 and the fan 100 is operating, the weight of the fan head 1 and the force generated by the fan blades 11 during operation will cause a gap between the top of the fan head 1 and the motor base 2. A gap adjustment part 162 is provided at the connection between the fan head 1 and the motor base 2 to adjust the gap, so as to ensure the reliability of the connection between the fan head 1 and the motor base 2 and avoid abnormal noise caused by gaps at the connection when the fan 100 is running, which would reduce the user's comfort.

[0203] In some embodiments, such as Figure 22 and Figure 23 As shown, the gap adjustment part 162 is constructed in the shape of an elongated strip, and the thickness of the middle part of the gap adjustment part 162 is greater than that of the rear ends at both ends, so that guide slopes are formed at both ends of the gap adjustment part 162. The gap adjustment part 162 can be located in the top or bottom region of the connection.

[0204] Furthermore, the gap adjustment part 162 is made of an elastic material. Specifically, when the fan head 1 is connected to the motor base 2, its own weight and the force generated when the fan 100 is operating will cause a fitting gap at the connection. The gap adjustment part 162 is set within the fitting gap at the connection. The weight of the fan head 1 and the force generated when the fan 100 is operating will act on the gap adjustment part 162 and be transmitted through the gap adjustment part 162. By making the gap adjustment part 162 of an elastic material, the force is weakened when transmitted through the gap adjustment part 162, improving the connection reliability. At the same time, it makes the operation of the fan 100 smoother and reduces the generation of abnormal noise.

[0205] In some embodiments, such as Figures 24-27 As shown, the motor base 2 is provided with a first engagement part 244, and the fan head 1 is provided with a second engagement part 163. The first engagement part 244 and the second engagement part 163 are adapted to engage and lock when screwed to a set position. Thus, the fan head 1 and the motor base 2 can be screwed together and installed, and the installation method is simple and easy to operate.

[0206] Furthermore, one of the first engagement portion 244 and the second engagement portion 163 is provided with an engagement rib 2441, and the other is provided with an engagement groove 1631. The engagement rib 2441 is engaged into the engagement groove 1631 along the circumference of the fan head 1.

[0207] Specifically, a screw-in rib 2441 can be provided in the first screw-in portion 244, and a screw-in groove 163 can be provided in the second screw-in portion 163. When the first screw-in portion 244 and the second screw-in portion 163 are screwed into a set position, the screw-in rib 2441 of the first screw-in portion 244 can be engaged with the screw-in groove 1631 of the second screw-in portion 163, thereby realizing the screw-in engagement connection between the first screw-in portion 244 and the second screw-in portion 163. Alternatively, the first screw-in portion 244 can be provided with a screw-in groove 1631, and the second screw-in portion 163 can be provided with a screw-in rib 2441. When the first engagement part 244 and the second engagement part 163 are engaged to the set position, the engagement groove 1631 of the first engagement part 244 can be engaged with the engagement rib 2441 of the second engagement part 163, thereby realizing the engagement and engagement connection between the first engagement part 244 and the second engagement part 163. Thus, both of the above-mentioned configuration methods can realize the engagement and engagement installation of the motor base 2 and the fan head 1. The installation of the motor base 2 and the fan head 1 is reliable, and the engagement connection method is simple, which facilitates the installation and connection of the motor base 2 and the fan head 1, and also facilitates the disassembly and maintenance in the future.

[0208] In this invention, such as Figures 24-27 As shown, a screw-in rib 2441 is provided in the first screw-in part 244, and a screw-in groove 1631 is provided in the second screw-in part 163. That is, a screw-in rib 2441 is provided inside the motor base 2, and a screw-in groove 1631 is provided at the rear end of the fan head 1. The screw-in rib 2441 of the motor base 2 can be screwed and locked into the screw-in groove 1631 of the fan head 1, realizing the screw-in locking installation of the motor base 2 and the fan head 1. The screw-in locking process has a self-locking function, making the installation of the motor base 2 and the fan head 1 more reliable, preventing the fan head 1 from loosening, and improving the safety of the fan 100. At the same time, when disassembly is required, the fan head 1 is rotated in the opposite direction to unlock the screw-in rib 2441 and the screw-in groove 1631, allowing the fan head 1 to be disassembled. With the above settings, the installation and disassembly of the fan head 1 and the motor base 2 are simpler and more convenient.

[0209] Therefore, by setting the motor base 2 with a screw-in rib 2441 and the fan head 1 with a screw-in groove 1631, the installation and disassembly of the motor base 2 and the fan head 1 can be simplified. The sound feedback generated during the screw-in engagement ensures that the motor base 2 and the fan head 1 are installed in place, which is convenient for users and improves the user experience.

[0210] In some embodiments, the fan head 1 includes a first mesh cover component, a fan blade 11, and a second mesh cover component. The first mesh cover component is detachably connected to the motor base 2, and the second mesh cover component is detachably connected to the first mesh cover component and adapted to define a mounting cavity. The fan blade 11 is rotatably mounted in the mounting cavity and is detachably connected to the second mesh cover component and / or the first mesh cover component. The fan blade 11 is poweredly connected to the drive member 241.

[0211] In practice, the fan head 1 is removed from the motor base 2. Specifically, the fan head 1 and the motor base 2 can be connected by rotation, plug-in, or fixed parts. When the fan head 1 is removed from the motor base 2, the fan blade 11 is also removed from the motor base 2. Then, the fan blade 11, the first mesh cover component, and the second mesh cover component are disassembled.

[0212] Furthermore, a portion of the fan blade 11 is detachably connected to the drive component 241 inside the motor base 2, passing through the first mesh cover component. Specifically, the portion of the fan blade 11 extending out of the first mesh cover component can be fitted onto the drive component 241, or the drive component 241 can be fitted onto the portion of the fan blade 11 extending out of the first mesh cover component. This facilitates connection and disassembly between the fan blade 11 and the drive component 241. After disassembling the fan blade 11, the first mesh cover component, and the second mesh cover component, the fan blade 11, the first mesh cover component, and the second mesh cover component can be disassembled separately, thereby disassembling all components of the entire fan head 1. The fan 100 of this embodiment can be disassembled again on the basis of one disassembly, allowing for deep cleaning of the fan 100 and facilitating quick and deep disassembly and assembly by the user.

[0213] In some embodiments, such as Figure 31 As shown, the first mesh cover component includes a first mesh cover 141, a flange 166, and a first locking member 167. The flange 166 includes a connected threaded connection section 1662 and a limiting section 1661. The limiting section 1661 is located inside the mounting cavity. The threaded connection section 1662 passes through the first mesh cover 141 and extends outside the first mesh cover 141. The first locking member 167 is threadedly connected to the threaded connection section 1662 and clamps the first mesh cover 141. The first mesh cover 141 is detachably connected to the second mesh cover component, and the fan blade 11 is rotatably supported on the flange 166 through a first bearing 1412.

[0214] Specifically, a flange 166 is connected to one end of the fan blade 11 near the first guard component. The fan blade 11 has a mounting hole, and a connecting structure is connected to the flange 166. This connecting structure is connected to the mounting hole of the fan blade 11 and is rotatably connected to the flange 166, i.e., the flange 166 protrudes to the left side of the mounting hole. The flange 166 has an axially extending threaded connection section 1662 and a limiting section 1661 connected circumferentially along the threaded connection section 1662. The threaded connection section 1662 extends out of the first guard 141 near the motor base 2 through the first connecting hole 1411 of the first guard 141. The first locking member 167 has an internal thread. The left end of the fan blade 11 is connected to the first guard 141 by the first locking member 167 sleeved on the threaded connection section 1662, and the first guard 141 is clamped by the limiting section 1661 and the first locking member 167.

[0215] In practice, the first mesh cover 141 is connected to the end of the fan blade 11, that is, the first mesh cover 141 is fixedly connected to the flange 166, and the first connecting hole 1411 is also provided with a first bearing 1412. The first bearing 1412 is rotatably connected inside the flange 166. The structure connected to the drive component 241 of the motor base 2 is rotatably connected to the structure inside the flange 166 through the first bearing 1412. In this embodiment of the invention, the end of the fan blade 11 near the first mesh cover 141 can be fixedly connected to the first mesh cover 141 through the flange 166, and the part of the fan blade 11 with the fan blade 152 is rotatably connected to the first mesh cover 141 through the first bearing 1412, the structure inside the flange 166, and the first mesh cover 141.

[0216] In some embodiments, the fan 100 further includes a locking structure, and the fan head 1 includes a first grille 141 and a second grille 142 detachably connected, such as Figures 28-29 As shown, the locking structure includes a push rod 164, which is movably mounted on the first mesh cover 141. The second mesh cover 142 is provided with a limiting part. When the motor base 2 is connected to the first mesh cover 141, the motor base 2 pushes the push rod 164 to be limited and locked by the limiting part.

[0217] In practical design, the fan head 1 can be rotatably connected to the motor base 2, or it can be axially inserted. Generally, the motor base 2 and the fan head 1 are circumferentially connected, such as... Figure 30 As shown, the pressing part 245 inside the motor base 2 presses against the top rod 164. When it is necessary to disassemble the fan head 1 from the motor base 2, the fan head 1 is first disassembled from the motor base 2. At this time, the pressing part 245 also disengages from the top rod 164, and then the fan head 1 disassembles the first mesh cover 141 and the second mesh cover 142. It should be noted that the position of the top rod 164 and the position where it cooperates with the pressing part 245 are located inside the fan 100. For example, most of the top rod 164 is located inside the fan head 1, and the position where the top rod 164 cooperates with the pressing part 245 is located between the fan head 1 and the motor base 2. This makes the structure of the top rod 164 hidden, so that the user cannot directly open the first mesh cover 141 and the second mesh cover 142 from the outside, ensuring the safety of the fan head 1.

[0218] Specifically, a radially movable push rod 164 can be provided on the side of the first mesh cover 141 away from the motor base 2, and the push rod 164 can move radially relative to the first mesh cover 141. At the same time, a limiting part is provided on the side of the second mesh cover 142 near the first mesh cover 141, and the limiting part has a limiting hole. The limiting hole of the limiting part can be radially aligned with the position of the push rod 164. When the push rod 164 moves radially, it can be more accurately inserted into or disengaged from the limiting hole, so that the push rod 164 can be connected to the second mesh cover 142 through the limiting part, and also prevent the second mesh cover 142 from circumferentially displaced.

[0219] Of course, as another embodiment of the present invention, the push rod 164 can also be radially arranged in the first mesh cover 141 but moved circumferentially to lock the second mesh cover 142. In this case, the structure and position of the pressing part 245 inside the motor base 2 are changed, so that the pressing part 245 pushes the side movement of the push rod 164. The limiting part of the push rod 164 and the second mesh cover 142 are configured as a bent structure, and the bent structure is consistent with the circumferential direction of the second mesh cover 142. The limiting part is also arranged in the circumferential direction of the second mesh cover 142, which can limit the circumferential movement of the push rod 164, and leave a gap in the circumferential direction of the first mesh cover 141. With a certain movement space, a limit can be set in the radial direction to prevent the top rod 164 from moving radially. The movement of the top rod 164 at this time is different from the radial movement of the top rod 164 mentioned above. When the pressing part 245 presses against the top rod 164 on the side, it pushes the top rod 164 to move along the circumference of the first mesh cover 141. When the top rod 164 moves along the circumference, the bent structure of the top rod 164 is connected to the limiting part of the second mesh cover 142. That is, the side of one end of the top rod 164 is pressed by the pressing part 245, and the other end is inserted into the limiting hole in the second mesh cover 142 along the circumference, which can also complete the connection between the first mesh cover 141 and the second mesh cover 142.

[0220] Among them, such as Figure 28 As shown, a limiting plate 143 can be provided on the first mesh cover 141. The limiting plate 143 can limit the position of the top rod 164. For example, the limiting plate 143 can define a sliding hole, through which the top rod 164 passes and can slide along the sliding hole. Simultaneously, as... Figure 30 As shown, the pressing part 245 may be provided with an arc-shaped pressing section 2451, which can press the push rod 164 to push the push rod 164 to move radially.

[0221] In some embodiments, such as Figure 29 As shown, the locking structure also includes a second elastic element 165, which is connected between the top rod 164 and the first mesh cover 141, and the second elastic element 165 is used to apply an elastic force away from the limiting part to the top rod 164.

[0222] In this embodiment, when the push rod 164 is located radially to the first mesh cover 141 and can move radially upwards, the second elastic element 165 can be a spring. The spring is located between the push rod 164 and the first mesh cover 141, with one end of the spring connected to the push rod 164 and the other end connected to the first mesh cover 141. When the push rod 164 moves, the spring will also deform. For example, when the push rod 164 is moved radially upwards away from the center of the first mesh cover 141, the spring is compressed. At this time, the bottom of the push rod 164 and the pressing part 245 in the motor base 2 are in a pressing state, so that even if the spring is compressed, it will not affect the radial upward movement of the push rod 164.

[0223] When the motor base 2 is disassembled from the fan head 1, the pressing part 245 inside the motor base 2 begins to disengage from the position where it is pressed against the push rod 164. At this time, the push rod 164 will be pushed back to its original state under the action of the second elastic element 165, so that the limiting part of the second mesh cover 142 is disengaged from the push rod 164 on the first mesh cover 141. At this time, the first mesh cover 141 and the second mesh cover 142 can be removed.

[0224] In some embodiments, such as Figure 32 As shown, a first heat dissipation cavity 251 for mounting the drive component 241 is formed inside the motor base 2. That is, the motor base 2 has a hollow structure with a first heat dissipation cavity 251, so that the drive component 241 can be installed inside the first heat dissipation cavity 251. A second heat dissipation cavity 171 for mounting the fan blade 11 is formed inside the fan head 1. That is, the fan head 1 has a hollow structure with a second heat dissipation cavity 171, so that the fan blade 11 can be installed inside the second heat dissipation cavity 171. The first heat dissipation cavity 251 and the second heat dissipation cavity 171 are connected. The first heat dissipation cavity 251 and the second heat dissipation cavity 171 can serve as both mounting chambers and heat dissipation chambers, realizing the sharing of space for mounting and heat dissipation.

[0225] like Figure 33 As shown, the motor mount 2 is provided with an air inlet 252 communicating with the first heat dissipation cavity 251. When the fan 100 is turned on for a long time, the drive component 241 inside the motor mount 2 will generate a lot of heat. If the heat is not effectively dissipated, the drive component 241 inside the motor mount 2 will remain at a high temperature for a long time, which will reduce the life of the motor or even burn it out. In this embodiment of the invention, by providing an air inlet 252 in the motor mount 2, when the fan blade 11 is poweredly connected to the drive component 241 and generates heat during operation, outside air can enter the first heat dissipation cavity 251 through the air inlet 252. Since the drive component 241 is located inside the first heat dissipation cavity 251, the air entering the first heat dissipation cavity 251 from the air inlet 252 will dissipate heat and cool the drive component 241.

[0226] Furthermore, the first heat dissipation cavity 251 and the second heat dissipation cavity 171 are connected, and the fan head 1 has an air outlet 172 connected to the second heat dissipation cavity 171. After the outside air enters the first heat dissipation cavity 251, the air in the first heat dissipation cavity 251 absorbs the heat of the drive component 241, thereby cooling the drive component 241. The second heat dissipation cavity 171 is provided on one side of the first heat dissipation cavity 251 and is connected to it. After the drive component 241 dissipates heat in the first heat dissipation cavity 251, the airflow in the first heat dissipation cavity 251 will flow into the second heat dissipation cavity 171, and the airflow in the second heat dissipation cavity 171 can be discharged through the air outlet 172 of the fan head 1, thereby dissipating heat from the drive component 241. At this time, the airflow that has absorbed the heat of the drive component 241 is discharged through the air outlet 172. It should be noted that the air inlet 252, the first heat dissipation cavity 251, the second heat dissipation cavity 171, and the air outlet 172 are all in a connected state. After the drive unit 241 drives the fan blade 11 to rotate, the fan blade 11 drives the airflow of the second heat dissipation cavity 171 to flow out of the air outlet 172, so that the second heat dissipation cavity 171 forms a negative pressure. Then, the negative pressure is used to make the external airflow flow through the air inlet 252 and the first heat dissipation cavity 251 into the second heat dissipation cavity 171 in sequence. During the flow, the drive unit 241 and the power connection position between the drive unit 241 and the fan blade 11 are cooled.

[0227] It should be noted that the air inlet 252 can be selectively set in various directions of the motor base 2, and the air inlet 252 only needs to be connected to the first heat dissipation cavity 251. The drive component 241 is axially set in the motor base 2. Therefore, the airflow from the air inlet 252 to the first heat dissipation cavity 251 can have a large-area contact with the drive component 241 located in the first heat dissipation cavity 251. When it reaches the second heat dissipation cavity 171 inside the fan head 1, the second heat dissipation cavity 171 is used to install the fan blade 11. The fan blade 11 can serve as the airflow drive component 241 to cool the user, and can also drive the airflow of the first heat dissipation cavity 251 to be discharged in the second heat dissipation cavity 171, thereby accelerating the discharge of airflow in the second heat dissipation cavity 171 and accelerating the heat dissipation effect of the drive component 241.

[0228] In some embodiments, such as Figure 32 As shown, the connection between the motor base 2 and the fan head 1 forms an installation space 255. The drive component 241 is connected to the first coupling component 242, and the fan blade 11 is connected to the second coupling component 153. The first coupling component 242 and the second coupling component 153 are dynamically coupled in the installation space 255.

[0229] The motor base 2 is provided with a first heat dissipation hole 253 that connects the first heat dissipation cavity 251 with the installation space 255, and the fan head 1 is provided with a second heat dissipation hole 173 that connects the second heat dissipation cavity 171 with the installation space 255.

[0230] Specifically, the motor base 2 is provided with an external insertion ring 22, which is located on the edge of the motor base 2 near the fan head 1. The diameter of the external insertion ring 22 is larger than the diameter of the motor base 2 itself, which facilitates the connection between the motor base 2 and the fan head 1. The fan head 1 is provided with an internal insertion ring 12, which extends on the side of the fan head 1 facing the motor base 2. The diameter of the external insertion ring 22 can be larger than the diameter of the internal insertion ring 12. Alternatively, the diameter of the internal insertion ring 12 can be larger than the diameter of the external insertion ring 22, so that the motor base 2 and the fan head 1 can be connected by mutual insertion or by insertion and rotation.

[0231] The outer insertion ring 22 is inserted and connected to the inner insertion ring 12, defining an installation space 255. The installation space 255 is connected between the first heat dissipation cavity 251 and the second heat dissipation cavity 171, that is, the installation space 255 is located at the transition connection between the fan head 1 and the motor base 2. The drive component 241 is provided with an output shaft 2411, and the output shaft 2411 is provided with a first coupling member 242. The fan blade 11 is provided with a connecting shaft 151, and the connecting shaft 151 is provided with a second coupling member 153. The first coupling member 242 and the second coupling member 153 are dynamically connected within the installation space 255. The output shaft 2411 is used to connect with the connecting shaft 151 of the fan blade 11 through the first coupling member 242 and the second coupling member 153. The motor drives the output shaft 2411 to rotate, the output shaft 2411 drives the connecting shaft 151 to rotate, and the connecting shaft 151 continues to drive the fan blade 11 to rotate, thereby causing the fan blade 11 to drive the surrounding air flow, which can complete the blowing of the fan 100.

[0232] Furthermore, at the mounting space 255 formed by the outer insertion ring 22 and the inner insertion ring 12, the output shaft 2411 and the connecting shaft 151 are connected by the first coupling member 242 and the second coupling member 153. The heat source of the drive member 241 includes the connection between the motor output shaft 2411 and the first coupling member 242, and the connection between the first coupling member 242 and the second coupling member 153. That is, the heat source is mainly concentrated at the mounting space 255. The airflow enters the first heat dissipation cavity 251 through the air inlet 252 of the motor base 2, and continues to reach the mounting space 255 through the first heat dissipation cavity 251. This can dissipate the heat source concentrated at the mounting space 255, thereby avoiding excessive temperature at the connection between the first coupling member 242 and the second coupling member 153 and extending the service life.

[0233] In some embodiments, the first coupling member 242 is detachably connected to the output shaft 2411 of the drive member 241 via a connector, which facilitates the installation and removal of the first coupling member 242.

[0234] Furthermore, the fan blades 11 inside the fan head 1 can be powered by the first coupling member 242, which is fixedly connected to the output shaft 2411, thereby causing the fan 100 to generate airflow. When the first coupling member 242 needs maintenance or replacement, the fan head 1 is removed from the connection point of the motor base 2, exposing the first coupling member 242. Then, the connector can be removed, making the first coupling member 242 movable relative to the output shaft 2411, thus allowing the first coupling member 242 to be removed and disassembled. When the first coupling member 242 needs to be installed, the first coupling member 242 is connected to the end of the output shaft 2411 and fixed by the connector. Then, the fan head 1 is fixedly connected to the motor base 2 to complete the installation of the first coupling member 242, saving maintenance and replacement time for the first coupling member 242.

[0235] In some embodiments, such as Figure 32 and Figure 37 As shown, the fan 100 also includes a protective cover 254, which is installed on the end face of the motor base 2 facing the fan head 1. The protective cover 254 is located on the end face of the motor base 2 facing the fan head 1, and the distance from the side of the protective cover 254 facing the fan head 1 to the electric drive component 241 is greater than a set distance. It should be noted that the electric drive component 241 can be configured as a drive motor, that is, the electric drive component 241 is a live component. When the user disassembles the fan head 1 from the motor base 2, the drive motor is easily exposed from the end of the motor base 2 facing the fan head 1 or creepage may occur. Consequently, when the user connects the first coupling component 242 and the second coupling component 153, the current on the electric drive component 241 may be diverted to the user.

[0236] In this invention, by using a protective cover 254 to shield the end face of the motor mount 2 facing the fan head 1, the protective cover 254 can shield the electric drive component 241, preventing the electric drive component 241 from being exposed at the end of the motor mount 2 facing the fan head 1. This prevents the user's hand from directly contacting the electric drive component 241. Simultaneously, the protective cover 254 increases the distance between the electric drive component 241 and the user's hand, thereby increasing the creepage distance between the electric drive component 241 and the user's hand, thus preventing a large amount of current from being conducted to the user and improving user safety. It should be noted that the set distance can be set according to safety regulations. After the protective cover 254 is installed on the motor mount 2, the increased creepage distance ensures that the user will not experience safety issues due to creepage after contacting the end of the motor mount 2.

[0237] like Figure 37As shown, the protective cover 254 is provided with a central heat dissipation hole 2541, which connects the first heat dissipation hole 253 and the second heat dissipation hole 173. That is to say, after the airflow flows out from the first heat dissipation hole 253, it can flow through the central heat dissipation hole 2541 to the second heat dissipation hole 173 and enter the second heat dissipation cavity 171, thereby facilitating the flow of airflow from the first heat dissipation hole 253 to the second heat dissipation hole 173. In other words, the protective cover 254 will not affect the heat dissipation inside the electric drive component 241, ensuring that the inside of the electric drive component 241 can still effectively dissipate heat.

[0238] In some embodiments, there are multiple first heat dissipation holes 253, multiple intermediate heat dissipation holes 2541 and multiple second heat dissipation holes 173, and the multiple first heat dissipation holes 253, multiple intermediate heat dissipation holes 2541 and multiple second heat dissipation holes 173 are distributed in a one-to-one correspondence along the axial direction of the electric drive component 241, so that the first heat dissipation holes 253, multiple intermediate heat dissipation holes 2541 and multiple heat dissipation holes 173 form multiple sets of heat dissipation channels, thereby increasing the airflow between the air inlet hole 252 and the air outlet hole 172, and enhancing the effective heat dissipation of the electric drive component 241 and the mating parts of the first coupling member 242 and the second coupling member 153.

[0239] In some embodiments, such as Figure 38 and Figure 39 As shown, one of the motor base 2 and the fan head 1 is provided with a movable active structure 261. The active structure 261 is provided with a third locking part 262. The other of the motor base 2 and the fan head 1 is provided with a fourth locking part 181. The third locking part 262 and the fourth locking part 181 are locked together, and the third locking part 262 and the fourth locking part 181 are adapted to be unlocked when the active structure 261 is compressed or stretched.

[0240] In other words, the active structure 261 can be located on the motor base 2 or on the fan head 1. When the active structure 261 is located on the motor base 2, the third latching part 262 is located on the motor base 2 and the fourth latching part 181 is located on the fan head 1. Conversely, when the active structure 261 is located on the fan head 1, the third latching part 262 is located on the fan head 1 and the fourth latching part 181 is located on the motor base 2, the connection between the motor base 2 and the fan head 1 can be achieved through either of the above two design methods.

[0241] Furthermore, such as Figure 39As shown, the motor base 2 and the fan head 1 are adapted to be connected by a third snap-fit ​​part 262 and a fourth snap-fit ​​part 181. That is, the fan head 1 can be connected to the motor base 2 by snap-fit. The snap-fit ​​connection method is simple and easy to install. The active structure 261 is set to unlock the third snap-fit ​​part 262 and the fourth snap-fit ​​part 181 when it is pressed or pulled. That is, when the active structure 261 is pressed or pulled up, the active structure 261 moves, which can make the third snap-fit ​​part 262 and the fourth snap-fit ​​part 181 displace and unlock, and the entire fan head 1 can be removed. The removed fan head 1 is not electrified. This method of removing the fan head 1 is simple, easy and convenient for disassembling and cleaning the entire fan head 1.

[0242] Therefore, by providing an active structure 261 in the motor base 2 or the fan head 1, the installation and removal of the fan head 1 can be made easier and more convenient. The fan head 1 can be detached independently from the motor base 2, allowing the user to remove the fan head 1 separately for easy cleaning, thereby increasing the frequency of cleaning the fan head 1 and ensuring that the fan 100 blows out clean air, resulting in a better user experience.

[0243] In some embodiments, such as Figure 39 As shown, the active structure 261 is configured to be pressable along the second direction. One of the motor base 2 and the fan head 1 is also provided with an elastic reset member 265. The elastic reset member 265 is used to elastically pre-tighten the active structure 261 along the third direction. The second direction is opposite to the third direction. The elastic reset member 265 can be provided on the motor base 2 or on the fan head 1. The elastic reset member 265 is arranged opposite to the active structure 261. The active structure 261 can be pressed along the second direction. The elastic reset member 265 can generate an elastic force along the third direction to elastically pre-tighten the active structure 261. The second direction is opposite to the third direction so that the third locking part 262 and the fourth locking part 181 are firmly locked together, so that the fan head 1 is firmly installed.

[0244] Specifically, if the second direction is from top to bottom and the third direction is from bottom to top, the active structure 261 is located inside the motor base 2, and the elastic reset member 265 is located at the lower end of the motor base 2, with the active structure 261 located above the elastic reset member 265. After the fan head 1 is connected to the motor base 2, the third locking part 262 of the active structure 261 engages with the fourth locking part 181. The elastic reset member 265 generates an upward elastic force, which can lock the third locking part 262 and the fourth locking part 181 together, thus ensuring the fan head 1 is securely installed. Therefore, by arranging the active structure 261 and the elastic reset member 265 facing each other, the active structure 261 and the elastic reset member 265 can interact, making the installation of the fan head 1 more secure and facilitating the disassembly of the fan head 1.

[0245] Among them, such as Figure 39As shown, the active structure 261 includes a limiting boss 263, and one of the motor base 2 and the fan head 1 is provided with a limiting groove 264. The elastic reset member 265 is constructed as a spring, with one end of the elastic reset member 265 sleeved on the limiting boss 263 and the other end extending into the limiting groove 264.

[0246] Specifically, the limiting boss 263 is located at the lower end of the active structure 261, and the limiting groove 264 can be located on the motor base 2 or on the fan head 1. The limiting boss 263 and the limiting groove 264 are arranged opposite to each other. One end of the elastic reset member 265 is sleeved on the limiting boss 263, and the other end extends into the limiting groove 264, which can complete the installation of the elastic reset member 265. By installing the elastic reset member 265 between the limiting groove 264 and the limiting boss 263, both ends of the elastic reset member 265 can be limited and fixed, making the installation of the elastic reset member 265 firm.

[0247] The limiting groove 264 can be provided on the motor base 2 and located at the bottom of the active structure 261. The limiting groove 264 is located below the limiting boss 263. The limiting boss 263 is cylindrical, and the limiting groove 264 is circular. The outer diameter of the limiting boss 263 is smaller than the inner diameter of the limiting groove 264, and the inner diameter of the limiting groove 264 is larger than the outer diameter of the elastic reset member 265. This allows the elastic reset member 265 to be better installed in the limiting boss 263 and the limiting groove 264, and makes the limiting of the elastic reset member 265 reliable. The elastic reset member 265 can be a spring. After the fan head 1 is pushed into the motor base 2, due to the weight of the fan head 1 itself, the fourth locking part 181 engages with the third locking part 262, which can achieve self-locking. At the same time, the fourth locking part 181 presses down on the third locking part 262 to move downward and compress the elastic reset member 265, so that the elastic reset member 265 generates an upward elastic force to balance the pressure. When the elastic reset member 265 is in a stable state, the installation of the fan head 1 also tends to be stable, making the installation of the fan head 1 firm and reliable.

[0248] Since the elastic reset member 265 mainly provides elastic force for the active structure 261, the installation structure of the elastic reset member 265 can be designed according to the actual situation. For example, a limiting boss 263 can be set at the lower end of the active structure 261, and the elastic reset member 265 can be sleeved on the outside of the limiting boss 263. The limiting boss 263 can install and limit the elastic reset member 265, realize the connection between the elastic reset member 265 and the active structure 261, and thus realize the elastic reset member 265 to apply elastic force to the active structure 261.

[0249] In some embodiments, such as Figure 40 and Figure 41As shown, one of the motor base 2 and the fan head 1 is provided with a retractable locking member 266 and the other is provided with a locking groove 182. The locking member 266 is adapted to lock with the locking groove 182 when the motor base 2 and the fan head 1 are connected.

[0250] In other words, a retractable locking element 266 can be provided in the motor base 2, and a locking groove 182 can be provided in the fan head 1. Alternatively, a retractable locking element 266 can be provided in the fan head 1, and a locking groove 182 can be provided in the motor base 2. Either of the above two design methods can achieve the plug-in connection between the motor base 2 and the fan head 1.

[0251] Furthermore, the motor base 2 and the fan head 1 are adapted to be locked with the locking groove 182 by the locking member 266 after insertion. That is, after the motor base 2 and the fan head 1 are inserted, the corresponding locking members 266 of the motor base 2 and the fan head 1 can be inserted into the locking groove 182 to achieve locking between the motor base 2 and the fan head 1. In other words, the installation of the motor base 2 and the fan head 1 can be completed after the motor base 2 and the fan head 1 are inserted and locked. The locking effect is good and effortless.

[0252] During installation, the motor base 2 is provided with a retractable locking member 266. The locking member 266 is provided on the side of the motor base 2 facing the fan head 1. The fan head 1 is provided with a locking groove 182, which is provided on the side of the fan head 1 facing the motor base 2. During installation, when the fan head 1 is pushed into the motor base 2, the locking member 266 is pushed into the locking groove 182 to lock, thus completing the connection between the fan head 1 and the motor base 2. After the locking member 266 is locked with the locking groove 182, the locking member 266 can lock the fan head 1 in both the circumferential and axial directions, resulting in a better locking effect. During disassembly, the fan head 1 can be pulled horizontally in the opposite direction. The pulling force causes the locking groove 182 to disengage from the locking member 266, unlocking the entire fan head 1. This allows the fan head 1 to be removed independently. The installation and disassembly steps are simple, convenient, and effortless, facilitating the cleaning of the entire fan head 1 and ensuring that clean air is blown out when the fan 100 is used, thereby improving the user experience.

[0253] Therefore, by making the fan head 1 independently detachable, the frequency of cleaning the fan head 1 can be increased. Users can remove the fan head 1 regularly every week for washing. Dust does not easily accumulate inside the fan head 1, and it is easy to clean.

[0254] In some embodiments, such as Figure 42 and Figure 43 As shown, the fan head 1 is plugged into the motor base 2. One of the fan head 1 and the motor base 2 is equipped with a rotatable second locking member 267. The second locking member 267 is configured to lock with the other of the fan head 1 and the motor base 2 after rotation.

[0255] In other words, the second locking member 267 can be installed on the fan head 1 or on the motor base 2. At the same time, the second locking member 267 can lock with the fan head 1 or the motor base 2 after rotation. When the second locking member 267 is installed on the fan head 1, it can lock with the motor base 2 after rotation; conversely, when the second locking member 267 is installed on the motor base 2, it can lock with the fan head 1 after rotation. Through the above two design methods, the connection and locking between the motor base 2 and the fan head 1 can be realized.

[0256] Furthermore, the fan head 1 is suitable for plugging into the motor base 2. This plug-in connection method is simple and easy to install. The second locking member 267 is configured to lock the fan head 1 and motor base 2 by rotating it in. When the second locking member 267 is rotated into the fan head 1 or motor base 2 in a certain direction, the other fan head 1 or motor base 2 can be locked, thus limiting the relative displacement between the fan head 1 and motor base 2, such as in a clockwise direction. When the second locking member 267 is rotated out of the fan head 1 or motor base 2 in a certain direction, the other fan head 1 or motor base 2 can be unlocked, such as in a counter-clockwise direction, thus allowing the fan head 1 to separate from the motor base 2. This enables the installation and removal of the fan head 1 relative to the motor base 2. This method of removing the fan head 1 is simple and easy, and facilitates disassembly and cleaning of the fan head 1.

[0257] Therefore, by setting the above-mentioned plug-in and locking method of the second locking member 267, the installation and disassembly of the fan head 1 is more convenient and effortless, and the fan head 1 can be easily cleaned, ensuring that clean air is blown out when the fan 100 is used, thereby improving the user experience. At the same time, the second locking member 267 fixes the position of the fan head 1 and the motor base 2, ensuring the firmness of the connection.

[0258] Among them, such as Figure 43 As shown, the locking member 267 includes a turning part 2671 and a locking part 2672. The locking part 2672 passes through the outer insertion ring 22 and is threadedly connected to the outer insertion ring 22. The turning part 2671 is connected to the locking part 2672 and extends to the outside of the outer insertion ring 22. The locking part 2672 is adapted to press against the inner insertion ring 12.

[0259] In some embodiments, at least one of the fan head 1 and the motor base 2 is provided with a buffer portion, and the fan head 1 and the motor base 2 are adapted to be pressed together by the buffer portion after being connected. In actual design, the fan head 1 and the motor base 2 can be connected by a threaded rotation or by an axial snap-fit. Regardless of the connection method, the buffer portion provided by either the fan head 1 or the motor base 2 provides a certain buffering force between the fan head 1 and the motor base 2 when they are connected. When the fan head 1 and the motor base 2 are connected, the buffer portion located on the fan head 1 and the motor base 2 provides pressure buffering. At this time, the buffer portion between the fan head 1 and / or the motor base 2 is an interference fit, such as a silicone buffer portion, which provides an elastic compression space between the fan head 1 and the motor base 2, absorbing the vibration problem caused by rotating parts such as the motor or fan blade 11, and also balancing the assembly gap well, thus having the functions of pre-tightening and buffering. The buffer portion can be a component made of soft materials such as silicone, a spring, or a bent structure that can be deformed under pressure.

[0260] In some embodiments, such as Figures 44-47 As shown, one of the fan head 1 and the motor base 2 is provided with a first buffer part 183 and the other is provided with a second buffer part 268. The first buffer part 183 and the second buffer part 268 are adapted to press against each other when the fan head 1 and the motor base 2 are connected. That is, the buffer part includes the first buffer part 183 and the second buffer part 268. The first buffer part 183 can be provided on the fan head 1 and the second buffer part 268 can be provided on the motor base 2. Of course, the first buffer part 183 can also be provided on the motor base 2 and the second buffer part 268 can be provided on the fan head 1. The first buffer part 183 and the second buffer part 268 can both be provided on the surfaces where the motor base 2 and the fan head 1 are connected. A second buffer portion 268 is provided on the mounting surface where the motor base 2 is connected to the fan head 1, and a first buffer portion 183 is also provided on the mounting surface where the fan head 1 is connected to the motor base 2. When the fan head 1 is connected to the motor base 2, the positions of the first buffer portion 183 and the second buffer portion 268 need to correspond so that the first buffer portion 183 and the second buffer portion 268 can be pressed together after the fan head 1 is connected to the motor base 2.

[0261] In practice, the structures of the first buffer part 183 and the second buffer part 268 can be the same or different, as long as the fan head 1 and the motor base 2 have a certain buffering and pre-tightening effect after installation. Furthermore, the materials used for the first buffer part 183 and the second buffer part 268 can be the same or different. For example, both the first buffer part 183 and the second buffer part 268 can be elastic materials, or at least one can be an elastic material. When one of the first buffer part 183 and the second buffer part 268 is an elastic material and the other is a rigid material, the material of the motor base 2 or the fan head 1 itself can be used as the first buffer part 183 or the second buffer part 268, with the elastic material of one serving as the buffer force after connection. When both the first buffer part 183 and the second buffer part 268 are elastic materials, both elastic materials can serve as the buffer force, so that after the fan head 1 and the motor base 2 are connected, they can be elastically pressed together, achieving a buffering and vibration absorption effect.

[0262] In some embodiments, the motor base 2 and the fan head 1 are circumferentially limited by a positioning structure, and the motor base 2 and the fan head 1 are adapted to be attracted and fixed by a magnetic attraction structure. Thus, when the motor base 2 and the fan head 1 are connected, they are first circumferentially limited by the positioning structure, which can be located at the connection point between the motor base 2 and the fan head 1. Specifically, the positioning structure can employ a groove-protrusion fit, which facilitates alignment between the motor base 2 and the fan head 1 during connection, allowing for quick connection and preventing relative circumferential displacement of the motor base 2 and the fan head 1 during connection, thus preventing circumferential displacement changes caused by vibration. The magnetic attraction structure is located between the connection point of the motor base 2 and the fan head 1. After the motor base 2 and the fan head 1 are positioned by the positioning structure, they are then attracted and fixed by the magnetic attraction structure located between them.

[0263] This allows the motor base 2 and the fan head 1 to be aligned and then magnetically connected, making the overall installation convenient and quick. It also enables the independent disassembly and installation of the fan head 1 and the motor base 2, facilitating effective cleaning of the fan 100 and saving time.

[0264] In some embodiments, such as Figure 48 and Figure 49 As shown, the magnetic attraction structure includes a first magnetic attraction part 269 and a second magnetic attraction part 184. One of the inner insertion ring 12 and the outer insertion ring 22 is provided with the first magnetic attraction part 269 and the other is provided with the second magnetic attraction part 184. The first magnetic attraction part 269 and the second magnetic attraction part 184 are distributed along the radial direction of the inner insertion ring 12.

[0265] In practice, the structures of the first magnetic suction part 269 and the second magnetic suction part 184 can be the same or different, as long as the first magnetic suction part 269 and the second magnetic suction part 184 can be attracted and locked to the fan head 1. The first magnetic suction part 269 and the second magnetic suction part 184 can be radially distributed along the position between the inner insertion ring 12 and the outer insertion ring 22, that is, radially distributed along the inner insertion ring 12 and radially distributed along the outer insertion ring 22. The positioning structure is also set at the connection between the fan head 1 and the motor base 2, which can effectively combine the positioning structure and the magnetic suction structure. Both the positioning structure and the magnetic suction structure are set in the limited connection space between the fan head 1 and the motor base 2, which can effectively lock and position the first magnetic suction part 269 and the second magnetic suction part 184.

[0266] In this configuration, one of the first magnetic attraction part 269 and the second magnetic attraction part 184 is a magnet and the other is made of a magnetic metal material; or, both the first magnetic attraction part 269 and the second magnetic attraction part 184 are magnets, and different methods are used to ensure that the first magnetic attraction part 269 and the second magnetic attraction part 184 can attract each other.

[0267] The present invention also proposes an assembly method for the fan 100.

[0268] According to the assembly method of the fan 100 of the present invention, the assembly method is applicable to the fan 100 described in any of the above embodiments, and as follows: Figure 50 As shown, the assembly method includes:

[0269] S1: The drive unit 241 is installed in the motor base 2 to form a first independent body. Thus, the motor base 2 and its internal structure can be regarded as an independent whole.

[0270] S2: Install the fan blade 11 inside the fan head 1 to form a second independent body. Thus, the fan head 1 and its internal structure can be regarded as an independent whole.

[0271] S3: Connect and lock the first independent unit to the second independent unit. Thus, when connecting and fixing the fan head 1 and the motor base 2, the first and second independent units can be connected and locked, ensuring the fan head 1 is stably installed on the motor base 2, achieving the connection and installation of the two. The fan head 1, as an independent unit, can be disassembled and replaced separately from the motor base 2, allowing users to increase the frequency of cleaning the fan head 1. For example, users can regularly remove the fan head 1 for washing every week. With increased washing frequency, dust is less likely to accumulate inside the fan head 1, and cleaning only requires rinsing with a tap, which is very convenient.

[0272] In some embodiments, S2: Connecting and locking the first independent body to the second independent body includes:

[0273] S21: The child lock component 3 is moved relative to the motor base 2, locking the child lock component 3 and the fan head 1. Simultaneously, the micro switch 23 is triggered to connect the power supply to the drive component 241. Therefore, in actual use, when the user connects the motor base 2 and the fan head 1, the child lock component 3 can be moved relative to the motor base 2 to lock the motor base 2 and the fan head 1, preventing the fan head 1 and motor base 2 from automatically separating during fan 100 use. Simultaneously, the child lock component 3 pushes the micro switch 23 to activate the drive component 241, 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 base 2, facilitating 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 component 241 and stopping the fan blades 11 from rotating.

[0274] 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 241 stops outputting driving force, so that the drive component 241 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 241 from causing damage to the user when disassembling the fan head 1. Moreover, when the drive component 241 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.

[0275] In some embodiments, S21: Driving the child lock component 3 to move relative to the motor base 2 includes:

[0276] S22: The sliding paddle 31 slides relative to the motor base 2. During its movement, the sliding paddle 31 pushes the locking pin 33 to lock against the fan head 1. The sliding paddle 31 is the driving component and 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 according to their own wishes. 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 the action of the sliding paddle 31. 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.

[0277] 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.

[0278] In some embodiments, S21: the movement of the child lock component 3 relative to the motor base 2 further includes:

[0279] S23: During movement, the sliding paddle 31 pushes the locking pin 33, triggering the micro switch 23 to open, thereby connecting the power supply to the drive unit 241. It should be noted that the micro switch 23 is normally open at this time; in other words, the micro switch 23 is in the open state when not subjected to external force. The child lock component 3 can contact the micro switch 23 during movement. Specifically, the design allows the sliding paddle 31 to trigger the micro switch 23 simultaneously when it locks the locking pin 33 against the fan head 1.

[0280] Alternatively, S24: During the movement of the sliding paddle 31, the switch block 32 is driven to release the pressure spring 231 of the micro switch 23, so that the power supply to the drive unit 241 is turned on. It should be noted that at this time, the micro switch 23 is constructed as a normally open switch, 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 drive unit 241 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.

[0281] In some embodiments, S3: Connecting and locking the first independent body to the second independent body includes:

[0282] S31: Pass the output shaft 2411 of the drive unit 241 through the mounting hole of the fan blade 11 and insert the motor base 2 into the fan head 1;

[0283] S32: Screw the fastener into the end of the output shaft 2411 away from the fan blade 11, and make the fastener axially limit the fan blade 11.

[0284] Therefore, by making the fan head 1 independently detachable, after actual installation, the output shaft 2411 can be connected and fixed with fasteners, which can also axially limit the fan blades 11, thus maintaining the fan blades 11 in a stable structural state, which is conducive to the continuous and stable output of airflow by the fan blades 11. The fasteners can be threaded structures such as nuts. During disassembly, the fasteners can be unscrewed from the output shaft 2411, and other structural components can be easily disassembled. The disassembly structure is simple and the disassembly process is easy to implement, which allows users to increase the frequency of cleaning the fan head 1. For example, users can regularly remove the fan head 1 for washing every week. With the increase of washing frequency, dust is less likely to accumulate inside the fan head 1, and washing only requires rinsing with a tap.

[0285] In actual assembly, the output shaft 2411 can be assembled and connected to the fan blade 11 in the horizontal direction, or it can be assembled with the fan blade 11 after the motor base 2 is adjusted to a certain angle left, right or up. Thus, the output shaft 2411 and the fan blade 11 can be assembled at different angles according to the user's needs.

[0286] Alternatively, a first coupling member 242 is provided on the output shaft 2411, and a second coupling member 153 extending from the mesh cover body 14 is provided on the fan blade 11. Wherein, S3: connecting and locking the first independent body and the second independent body includes:

[0287] S33: The fan head 1 of the second independent unit is rotated and locked to the motor base 2 of the first independent unit, while the first coupling member 242 of the drive member 241 and the second coupling member 153 of the fan blade 11 are power-coupled. Thus, during actual installation, the motor base 2 and the fan head 1 are rotated relative to each other to achieve assembly and connection, and simultaneously the motor and fan blade 11 are connected and installed. During disassembly, the motor base 2 and the fan head 1 are rotated relative to each other in opposite directions to achieve disassembly and separation, and simultaneously the motor and fan blade 11 are disassembled. This greatly saves installation steps, improves installation efficiency, and enhances the user experience.
