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

[0113] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0114] Reference below Figure 1-Figure 49 The fan 100 according to an embodiment of the present invention is described. The fan head 1 of the fan 100 can be independently disassembled relative to the motor base 2, so that the fan head 1 can be removed for independent cleaning, which is convenient for cleaning, thereby allowing the fan 100 to blow out clean air and improve user experience.

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

[0116] A driving member 241 is provided in the motor base 2, and the driving member 241 can be set as a motor, and the motor is used to output driving force. In actual design, the motor base 2 can be installed on a placement surface, or a base 4 is provided below the motor base 2, so as to be installed on the placement surface through the base 4. The placement surface can be the ground or a desktop, etc., and a support plate 41 can be provided below the base 4. The support area of ​​the support plate 41 is large, which can ensure that the fan 100 is stably supported on the placement surface, thereby improving the placement stability of the fan 100.

[0117] The fan head 1 is provided with rotatable blades 11, and the fan head 1 is detachably connected to the motor base 2. The blades 11 are detachably connected to the driving member 241 by power, and the driving member 241 is used to drive the blades 11 to rotate. In other words, the fan head 1 can be flexibly installed and removed relative to the motor base 2, that is, when the fan 100 is working normally, the fan head 1 can be installed on the motor base 2, and when the fan 100 needs to be cleaned and repaired, the fan head 1 can be removed from the motor base 2. Therefore, the fan head 1 is independently detachable relative to the motor base 2, which makes it convenient for users to clean and repair the removed fan head 1.

[0118] After the fan head 1 is installed and connected with the motor base 2, the motor is connected to the fan blades 11, and the motor can drive the fan blades 11 to rotate to deliver airflow in the indoor space. After the fan head 1 is disassembled and separated from the motor base 2, the motor is disconnected from the fan blades 11. At this time, the live part and the non-live part of the fan 100 are relatively separated, and the user can disassemble and clean the non-live part of the fan head 1, which is not only convenient for disassembly and cleaning, but also can achieve non-electrical cleaning, improve the safety of the cleaning process, and the disassembled fan head 1 is not electrically charged as a whole and can be directly washed.

[0119] Therefore, by setting the fan head 1 to be independently detachable, it is convenient for the user to increase the number of times the fan head 1 is cleaned. For example, the user can regularly remove the fan head 1 every week for flushing. As the number of cleanings increases, dust is not easily accumulated inside the fan head 1, ensuring that the air blown out is cleaner. The detached independent fan head 1 can be directly flushed with a faucet when cleaning, which is very convenient. In contrast, the current mesh-covered fan 100 is generally less frequently cleaned because the fan blades 11 and the mesh cover are inconvenient to remove. The long use time of the fan 100 will cause dirt to accumulate inside and in the gaps of the grille. The cleaning time is long, which brings a bad experience to the user. The design of the fan 100 in the present invention solves the problem of inconvenient cleaning.

[0120] According to the fan 100 of the embodiment of the present invention, by configuring the fan 100 so that the fan head 1 is detachable relative to the motor base 2, the user can increase the number of cleaning times of the fan head 1. When the fan 100 is detached relative to the motor base 2, the fan blades 11 are also connected and separated relative to the driving member 241, which is convenient for the user to clean the fan head 1 and the fan blades 11 inside, thereby ensuring that dust is not easily accumulated in the fan head 1, ensuring that the blown air is cleaner, and the fan head 1 is safer during cleaning, thereby improving the user experience.

[0121] In some embodiments, Fig.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, which is suitable for driving the airflow in the fan head 1 to flow toward the air outlet 172 along the axial direction of the axial flow fan blade. In other words, the fan blade 11 of the fan 100 in the present invention is different from the traditional centrifugal fan blade 11, and can realize axial air intake and axial air outlet, wherein, during actual operation, the axial flow fan blade rotates, and drives the airflow at the rear side of 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 transported toward the user's face.

[0122] It should be noted that, Fig.33 As shown, the fan head 1 can be provided with an air inlet 252. The air inlet 252 can be provided on the rear side of the fan head 1 for axial air inlet, or can be provided on the circumferential outer side of the fan head 1 for oblique air inlet. Both of these can realize the air inlet function of the fan head 1, and the airflow entering the fan head 1 can flow to the axial rear end of the axial flow fan blade, and then flow axially forward to the air outlet 172 under the action of the axial flow fan blade. In particular, the air inlet 252 can be provided on the rear side of the fan head 1, and a heat dissipation channel can be provided in the motor base 2 at the same time, so that the heat dissipation channel is connected with the air inlet 252, and then under the driving action of the axial flow fan blade, the airflow is driven to dissipate the heat for the driving component 241 etc. in the heat dissipation flow, and then flows from the air inlet 252 to the user, which is not only beneficial to air supply, but also can realize the 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 driving member 241, and / or the ratio of the radial dimension of the fan head 1 to the axial dimension is greater than or equal to 1. Therefore, the fan 100 in the present invention is different from the traditional crossflow impeller. It should be noted that the traditional tower fan uses a crossflow impeller, and the radial dimension of the tower fan at various axial positions does not change significantly, while the radial dimension of the fan head 1 in the present invention is much larger than the radial dimension of the motor base 2 at the driving member 241.

[0124] At the same time, compared with centrifugal fan blades, the provision of axial flow fan blades is conducive to more stable placement of the fan head 1 and the motor base 2, thereby ensuring the stability of the position state of the fan 100.

[0125] In some embodiments, the fan head 1 is adapted to be connected to the motor base 2 along a first direction when in the initial position, the first direction being along the axial direction of the fan blade 11, and the first direction intersecting with the vertical direction. That is, when the fan head 1 is in the initial position relative to the motor base 2, the fan head 1 can be moved relative to the motor base 2 along the first direction, so that the fan head 1 is connected and fixed to the motor base 2, such as Figure 1 As shown, the first direction is along the horizontal direction, and the fan head 1 can be installed on the front end of the motor base 2 from front to back along the horizontal direction to achieve the connection and fixation of the two along the horizontal direction.

[0126] The first direction may also form a certain inclination angle relative to the horizontal direction and intersect with the vertical direction, that is, the first direction may be inclined upward or downward relative to the horizontal direction, so that the installation of the fan head 1 is more flexible.

[0127] The fan head 1 is configured to be able to swing up and down and / or left and right relative to the motor base 2 from an initial position, that is, after the fan head 1 is connected and fixed to the motor base 2, the user can adjust the angle of the fan head 1. For example, the fan head 1 and the motor base 2 are installed together on the base 4, and the fan head 1 can be driven to adjust in different directions such as up, down, left and right relative to the base 4. At this time, the fan head 1 can be adjusted until its axis is parallel to the vertical direction, so that the adjustment range of the fan head 1 is larger, thereby meeting the user's air supply needs in more directions.

[0128] In some embodiments, the fan head 1 as a whole is independently removable relative to the motor base 2, so that the fan head 1 can be completely independently removed from the motor base 2. In this way, when the user cleans the fan 100, the fan head 1 can be cleaned independently, which not only helps to improve the cleaning efficiency, but also facilitates the user to increase the cleaning frequency, ensuring that the fan 100 can always blow out fresh and clean wind, thereby improving the user experience.

[0129] Among them, it is also necessary to explain that in actual design, the fan head 1 and its internal fan blades 11 and other structural parts can be regarded as a whole. At the same time, the motor base 2 and its internal motor and other structural parts can be regarded as a whole. When the fan head 1 and the motor base 2 are disassembled and installed as a whole, the mesh cover body 14 of the fan head 1 and the shell of the motor base 2 can be directly disassembled or connected. The disassembly structure is simple and the connection relationship is not complicated, which greatly reduces the disassembly time of the fan head 1 relative to the motor base 2. At the same time, after the fan head 1 is disassembled from the motor base 2 as an independent body, the user can clean the fan head 1 as a whole, or disassemble and clean the internal structural parts of the fan head 1 to meet the user's cleaning needs.

[0130] In some embodiments, Figure 2 As shown, the fan 100 further includes a child lock component 3, which can be movably mounted on the motor base 2 and is used to selectively lock with the fan head 1. Therefore, in actual use, the user connects the motor base 2 with the fan head 1. After the connection, the child lock component 3 can be driven to move relative to the motor base 2 so that the child lock component 3 locks the motor base 2 with the fan head 1, thereby preventing the fan head 1 from automatically separating from the motor base 2 during the use of the fan 100.

[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, so as to facilitate the separate disassembly of the fan head 1; similarly, when the user installs the fan head 1 on the motor base 2, the fan head 1 can be docked with the motor base 2 first, and then the child lock component 3 can be driven to move relative to the motor base 2, so that the child lock component 3 can lock the motor base 2 and the fan head 1, thereby preventing the fan head 1 from automatically falling off from the motor base 2, thereby ensuring the stability of the installation of the fan head 1 and improving the reliability of the operation of the fan 100.

[0132] In some embodiments, Figure 4-Figure 10 As shown, the child lock component 3 includes a sliding paddle 31 and a locking pin 33. The sliding paddle 31 and the locking pin 33 can be movably installed on the motor base 2. The sliding paddle 31 and the locking pin 33 are slidably matched. The sliding paddle 31 is suitable for driving the locking pin 33 and the fan head 1 to selectively lock when it moves relative to the motor base 2.

[0133] That is to say, the sliding paddle 31 and the locking pin 33 can move respectively relative to the motor base 2, and the two can move relative to the motor base 2 in different directions, and the two use the direction of sliding cooperation to realize the driving of the locking pin 33 by the sliding paddle 31.

[0134] Among them, the sliding paddle 31 is an active part, and the sliding paddle 31 can be at least partially exposed outside the motor base 2, so that the user can actively operate the sliding paddle 31, so that the user can flexibly operate the sliding paddle 31 according to his own wishes to drive the locking pin 33. The locking pin 33 is a driven part. When the sliding paddle 31 moves, the locking pin 33 moves relative to the motor base 2 under the action of the sliding paddle 31, and the locking pin 33 has a locking position and an unlocking position relative to the motor base 2. When the locking pin 33 is in the locking position, the locking pin 33 can be limited and fixed with the fan head 1 to lock the fan head 1 relative to the motor base 2, that is, at this time, the user cannot disassemble the fan head 1 relative to the motor base 2, and when the locking pin 33 is in the unlocking position, the fan head 1 is unlocked relative to the motor base 2, and the user can flexibly disassemble the fan head 1.

[0135] Furthermore, in the specific structure, the motor base 2 can be rotatably engaged with the fan head 1, that is, the fan head 1 can be rotatably installed on the motor base 2, and a locking hole 13 can be provided on the fan head 1. After the fan head 1 is rotated into position relative to the motor base 2, the locking pin 33 can extend into the locking hole 13 and limit the reverse rotation of the fan head 1 relative to the motor base 2, thereby preventing the fan head 1 from automatically rotating and disassembling relative to the motor base 2. During disassembly, the locking pin 33 can be driven to extend from the locking hole 13 by the sliding paddle 31. At this time, the locking pin 33 no longer has a circumferential limiting effect on the fan head 1, thereby allowing the fan head 1 to be disassembled relative to the motor base 2. The structure is simple, which is conducive to the flexible locking and unlocking of the fan head 1 and the motor base 2.

[0136] The sliding paddle 31 can slide along the circumference of the motor base 2, wherein a mounting slot extending along the circumference can be provided on the motor base 2, the sliding paddle 31 penetrates and is installed at the mounting slot, and the sliding paddle 31 can slide along the mounting slot relative to the motor base 2. When the user operates the child lock component 3, the sliding paddle 31 can be directly pushed to move relative to the motor base 2.

[0137] The locking pin 33 slides along the radial direction or vertical direction of the motor base 2, so that the locking pin 33 can move inward or outward along the radial direction of the motor base 2 relative to the motor base 2, so that the locking pin 33 moves to different position states. Among them, one of the sliding paddle 31 and the locking pin 33 is provided with a sliding guide groove 316 and the other is provided with a sliding guide rail 332, and the sliding paddle 31 and the locking pin 33 are slidably matched through the sliding guide rail 332 and the sliding guide groove 316. In other words, the sliding direction of the locking pin 33 and the motor base 2 can be flexibly set, and the locking pin 33 can preferably slide vertically relative to the motor base 2. In this way, when the locking pin 33 moves relative to the motor base 2, the locking pin 33 can slide down relative to the motor base 2 by gravity, which is conducive to improving the reliability of the downward movement of the locking pin 33.

[0138] Therefore, when the sliding paddle 31 moves relative to the motor base 2, the sliding guide rail 332 contacts the inner wall surface of the sliding guide groove 316 to realize the driving effect of the sliding paddle 31 on the locking pin 33. The structure is simple and the matching method is easy to realize.

[0139] In some embodiments, Fig. 9 As shown, the sliding guide groove 316 is provided in the sliding paddle 31, and a sliding guide surface 317 is formed in the sliding guide groove 316, and the sliding guide surface 317 is pressed against the locking pin 33. In other words, the sliding paddle 31 can be constructed as a hollow structure to form a sliding guide groove 316 in the sliding paddle 31. Specifically, the sliding paddle 31 includes two inner walls that are relatively distributed, 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, so that during actual installation, the outer end of the locking pin 33 is extended into the sliding paddle 31 to achieve sliding cooperation between the two. The cooperation between the two sets of sliding guide grooves 316 and the sliding guide rail 332 is conducive to ensuring the support stability of the locking pin 33, and increasing the contact area, so as to achieve effective driving of the locking pin 33.

[0140] Among them, the distance between the sliding guide surface 317 and the axis of the motor seat 2 is set to gradually increase along the circumference of the motor seat 2. In other words, the sliding guide surface 317 is constructed as a curved surface, and when the sliding paddle 31 moves along the circumference of the motor seat 2, the sliding guide surface 317 can use its own inclined and curved setting to push the locking pin 33 to move radially relative to the motor seat 2. Specifically, if the distance between the sliding guide surface 317 and the axis of the motor seat 2 is set to gradually increase along the clockwise direction of the motor seat 2, when the sliding paddle 31 slides in the clockwise direction relative to the motor seat 2, the sliding guide surface 317 pushes the locking pin 33 to move radially inwardly along the motor seat 2 to lock with the fan head 1; and when the sliding paddle 31 slides in the counterclockwise direction relative to the motor seat 2, the sliding guide surface 317 pushes the locking pin 33 to move radially outwardly along the motor seat 2 to unlock with the fan head 1. The structure is simple and the driving process is easy to implement.

[0141] In some embodiments, Fig. 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, and the first limiting rib 311 and the second limiting rib 312 are formed with sliding guide surfaces 317 on the sides facing each other, that is, when the sliding paddle 31 moves relative to the motor base 2, the first limiting rib 311 and the second limiting rib 312 can both push the locking pin 33 to move, thereby realizing the locking or unlocking of the locking pin 33 and the fan head 1.

[0142] Specifically, a first limiting rib 311 and a second limiting rib 312 are provided on the inner side wall of the sliding guide groove 316, and the first limiting rib 311 and the second limiting rib 312 are spaced apart in the radial direction of the motor base 2, wherein the first limiting rib 311 is located on the outer side of the second limiting rib 312, and the sliding guide surface 317 of the first limiting rib 311 and the sliding guide surface 317 of the second limiting rib 312 are relatively distributed, wherein when the sliding paddle 31 moves along the circumferential direction of the motor base 2, the two limiting ribs can push the locking pin 33 from different directions respectively.

[0143] In some embodiments, Figure 6 , Figure 8-Figure 9 As shown, the sliding paddle 31 is provided with a locking tooth surface 313, and the locking tooth surface 313 extends along the movement direction of the sliding paddle 31, and the locking pin 33 is provided with a first elastic member 34 and a pressing member 35, and the first elastic member 34 is connected between the locking pin 33 and the pressing member 35 and is used to press the pressing member 35 toward the locking tooth surface 313, so that the elastic force of the first elastic member 34 can be used to keep the pressing member 35 in contact with the locking tooth surface 313, so that when the sliding paddle 31 rotates relative to the motor base 2, the pressing member 35 can cooperate with the locking tooth surface 313 to produce a sense of jamming, thereby helping to enhance the user's rotation feel.

[0144] The locking tooth surface 313 is disposed in the sliding paddle 31, and the locking tooth surface 313 is located on the side of the sliding paddle 31 facing the axis of the motor seat 2, and the outer end of the pressing member 35 can extend into the sliding paddle 31 to abut against the locking tooth surface 313. Therefore, when the sliding paddle 31 slides along the circumference of the motor seat 2, the outer end of the pressing member 35 can always press against the locking tooth surface 313, and the pressing member 35 can generate a sense of frustration with the tooth surface when switching to different tooth positions, thereby enhancing the user's hand feeling when pushing the sliding paddle 31.

[0145] It should be noted that if Fig.10 As shown, the sliding paddle 31 includes a paddle body 314 and a paddle cover 315, the paddle cover 315 is connected to the paddle body 314, the paddle body 314 penetrates along the radial direction of the motor seat 2, and the paddle cover 315 is connected to the side of the paddle body 314 away from the motor seat 2, so that the side of the paddle body 314 away from the motor seat 2 is in a closed state. Specifically, the first limiting rib 311 and the second limiting rib 312 are both provided on the paddle body 314, and the locking tooth surface 313 is provided on the side of the paddle cover 315 facing the inside of the paddle body 314. In other words, when the locking pin 33 extends into the sliding paddle 31, the locking pin 33 and the paddle body 314 are slidably matched, and at the same time, the pressing member 35 in the locking pin 33 is pressed against the paddle cover 315, thereby effectively pushing the locking pin 33, and generating a significant sense of frustration, thereby improving the user experience.

[0146] In some embodiments, the locking tooth surface 313 extends along the circumference of the motor base 2, that is, the extension direction of the locking tooth surface 313 is the same as the movement direction of the sliding paddle 31 relative to the motor base 2. At the same time, the distance from the locking tooth surface 313 to the axis of the motor base 2 is set to gradually increase along the circumference of the motor base 2. In other words, the extension direction of the locking tooth surface 313 is the same as the extension direction of the sliding guide groove 316, so that the pressing fit between the pressing member 35 and the locking tooth surface 313 can adapt to the fit between the locking pin 33 and the sliding guide groove 316.

[0147] In some embodiments, Figure 6 As shown, the locking pin 33 is provided with a mounting groove 331, and the mounting groove 331 is opened radially outwardly along the motor base 2. At least part 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 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, avoiding the first elastic member 34 from deforming in the radial direction and failing to provide 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 piece 35 is located in the mounting groove 331, the first elastic piece 34 is located in the mounting groove 331, and the lower end of the first elastic piece 34 is pressed against the inner bottom wall of the mounting groove 331, and the upper end of the first elastic piece 34 is pressed against the pressing piece 35, so that the pressing piece 35 always maintains an upward pre-tightened state, and then extends to the outside of the mounting groove 331 and presses into contact with the locking tooth surface 313, wherein the first elastic piece 34 will not bend radially when elastically deformed, and can stably apply an axial force to the pressing piece 35, thereby ensuring the pressing pressure of the pressing piece 35 on the locking tooth surface 313.

[0149] In some embodiments, Figure 6 As shown, a conical pressing portion 351 is formed at the end of the pressing member 35, and the conical pressing portion 351 is suitable for pressing and cooperating with the locking tooth surface 313. For example, the upper end of the pressing member 35 is constructed as the conical pressing portion 351, and the tip of the conical pressing portion 351 can be snapped into the tooth groove of the locking tooth surface 313, and as the sliding paddle 31 slides, the tip of the conical pressing portion 351 can be switched to different tooth grooves in turn, and the sudden switching of the tip at the crest and trough of the tooth groove can produce an obvious sense of frustration, thereby improving the user's hand feel.

[0150] and / or, if Figure 6 As shown, a limiting ring 352 can be provided on the outer peripheral wall of the pressing member 35, and one end of the first elastic member 34 is sleeved outside the pressing member 35 and pressed against the limiting ring 352, so that the limiting ring 352 can play a limiting role at the end of the 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] Among them, in actual construction, the pressing piece 35 can be constructed with both ends symmetrical relative to the middle part, that is, the limiting ring 352 is arranged in the middle part of the length direction of the pressing piece 35, and the upper and lower ends of the pressing piece 35 are formed with conical pressing portions 351, the conical pressing portion 351 at the upper end is in pressing contact with the locking tooth surface 313, and the conical pressing portion 351 at the lower end is in pressing contact with the inner bottom wall of the mounting groove 331, the first elastic piece 34 is sleeved outside the lower end part of the pressing piece 35, and the upper end of the first elastic piece 34 is pressed against the limiting ring 352, so that the pressing piece 35 can also play a role of radial limiting the first elastic piece 34.

[0152] In some embodiments, Figure 4-Figure 8 As shown, the motor base 2 is provided with a micro switch 23, and the micro switch 23 is used to control the power state of the driving member 241, that is, the opening or closing of the driving member 241 can be controlled by controlling the micro switch 23, such as the micro switch 23 can be set as a normally-off switch or a normally-on switch, and the user can actively operate the micro switch 23 to flexibly switch the power state of the driving member 241, so as to flexibly select the driving state of the fan blade 11. It should be noted that the micro switch 23 can be used to directly start or shut down the driving member 241; the micro switch 23 can also be used to control the working circuit of the driving member 241, such as when the micro switch 23 is disconnected, the working circuit cannot be connected or closed, and when the micro switch 23 is closed, the working circuit can be connected or closed, so as to flexibly switch the working state of the driving member 241 and the fan blade 11.

[0153] The child lock component 3 is also used to selectively trigger the micro switch 23 when it moves relative to the motor base 2, that is, the micro switch 23 can be driven to open or close by the action on the child lock component 3, thereby controlling the power output state of the driving member 241. In other words, the user can drive the child lock component 3 to move relative to the motor base 2 in one direction so that the child lock component 3 can selectively trigger the micro switch 23, or can drive the child lock component 3 to move relative to the motor base 2 in another direction so that the child lock component 3 does not contact the micro switch 23 and thus chooses not to trigger the micro switch 23. It should be noted that the micro switch 23 can be built into the motor base 2 so that users, including children, cannot touch the micro switch 23, thereby avoiding safety problems caused by users directly touching the micro switch 23. The child lock component 3 can be used to achieve the connection locking between the motor base 2 and the fan head 1, and can also be used to trigger the micro switch 23 to achieve power control of the driving member 241.

[0154] Therefore, by setting the child lock component 3 and the micro switch 23, when the user disassembles the fan head 1, the power of the driving member 241 can be automatically cut off, and after the fan head 1 and the motor base 2 are installed, the driving member 241 can be automatically connected, thereby preventing the driving member 241 and the rotating fan blades 11 from causing harm to the user, thereby improving the safety of the use of the fan 100.

[0155] In some embodiments, the micro switch 23 is configured as a normally-off switch, in other words, the micro switch 23 is in an off state when not acted upon by an external force. When the sliding paddle 31 moves relative to the motor base 2, it can press against the micro switch 23 to turn on the micro switch 23. At this time, the sliding paddle 31 is located at the right position, and there is no contact between the sliding paddle 31 and the micro switch 23. The micro switch 23 is in an off state, and the driving member 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, so that the micro switch 23 is turned on, and the driving member 241 can output power.

[0156] Alternatively, the micro switch 23 is constructed as a normally-on switch, in other words, the micro switch 23 is in an on state when not acted upon by an external force. When the sliding paddle 31 moves relative to the motor base 2, it can press against the micro switch 23 to disconnect the micro switch 23. At this time, the sliding paddle 31 is located at the right position, and there is no contact between the sliding paddle 31 and the micro switch 23. The micro switch 23 is in an on state, and the driving member 241 can output power. 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, so that the micro switch 23 is disconnected, thereby cutting off the power of the driving member 241.

[0157] In some embodiments, Figure 6 and Figure 7 As shown, the micro switch 23 is provided with a pressing spring piece 231, and the child lock component 3 is connected to a switch pressing block 32, the switch pressing block 32 and the pressing spring piece 231 are distributed along the circumference of the motor base 2, and the switch pressing block 32 is suitable for pressing or releasing the pressing spring piece 231 when the child lock component 3 moves relative to the motor base 2. Therefore, when the child lock component 3 slides relative to the motor base 2, the switch pressing block 32 moves relative to the motor base 2 along with the child lock component 3, and then gradually presses or releases the pressing spring piece 231 during the movement process, so as to switch the working state of the micro switch 23.

[0158] Specifically, the sliding paddle 31 is connected to the switch pressing block 32, and the sliding paddle 31 is suitable for driving the switch pressing block 32 to press the pressing spring piece 231 when driving the locking pin 33 to unlock the fan head 1. If the micro switch 23 is constructed as a normally-on switch, when the sliding paddle 31 moves relative to the motor base 2, the locking pin 33 is driven to unlock the fan head 1, and at the same time, the switch pressing block 32 presses the pressing spring piece 231 of the micro switch 23, so that the pressing spring piece 231 disconnects the micro switch 23 after deformation, thereby cutting off the power output of the driving member 241, and realizing the stopping of the fan blade 11.

[0159] Similarly, when the sliding paddle 31 moves in the opposite direction, the sliding paddle 31 drives the locking pin 33 to lock the fan head 1, and can also drive the switch pressing block 32 to actuate the microswitch 23, so that the microswitch 23 connects the power supply of the driving member 241, realizes the power output of the driving member 241, and drives the fan blades 11 to rotate. The structure is simple, and the locking of the motor base 2 and the fan head 1 and the synchronous control of the driving force of the driving member 241 can be realized, and the operation is convenient.

[0160] In some embodiments, Figure 4 As shown, the motor base 2 is provided with a pressing spring block 21, which is used to lock with the child lock component 3 when the child lock component 3 moves to the unlocked position, so that the child lock component 3 remains in a stable position when it moves to the unlocked position, and prevents the child lock component 3 from automatically moving relative to the motor base 2. In this way, when the fan head 1 is installed and connected to the motor base 2 again, the position of the child lock component 3 is in an unlocked state, which is conducive to the re-installation of the motor base 2 and the fan head 1.

[0161] Among them, a pressing spring block 21 is provided on the motor base 2, and the pressing spring block 21 is located in the movement direction of the child lock component 3. When the sliding paddle 31 moves, it can drive the switch pressure 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 process, and then the limiting structure on the pressing spring block 21 is used to achieve limiting fixation, thereby locking the position of the child lock component 3.

[0162] In some embodiments, Figure 7 As shown, the pressing spring block 21 is provided with an elastic column 211, and the elastic column 211 can be elastically retracted. The child lock component 3 is provided with a limiting opening. When the child lock component 3 moves to the unlocking position, the elastic column 211 extends into the limiting opening. Therefore, when the child lock component 3 is moved to the unlocking position, the elastic column 211 and the limiting opening can cooperate to achieve relative fixation of the two, thereby achieving position locking of the child lock component 3.

[0163] Specifically, during actual installation, a spring may be provided on the elastic column 211, and a fixing hole may be provided in the pressing spring block 21, so that one end of the elastic column 211 is elastically connected to the fixing hole through the spring, and the end of the elastic column 211 elastically extends out from the surface of the pressing spring block 21. When the child lock component 3 is moved toward the elastic column 211, the child lock component 3 pushes the elastic column 211 to contract, and when the elastic column 211 is directly opposite to the limiting opening, the elastic column 211 elastically extends into the limiting opening to achieve position locking of the child lock component 3, and when the user needs to lock the motor seat 2 and the fan head 1 through the child lock component 3, the child lock component 3 may be pushed to move relative to the motor seat 2, so that the pressing spring block 21 presses against the elastic column 211 and overcomes the elastic force of the spring, so that the elastic column 211 contracts, and the child lock component 3 is unlocked relative to the pressing spring block 21, and the structure is simple.

[0164] In some embodiments, the motor base 2 is provided with a first limit portion and a second limit portion, and the child lock component 3 is provided with a first clamping portion and a second clamping portion. The first limit portion is used to clamp and limit with the first clamping portion in the unlocked position, and the second limit portion is used to clamp and limit with the second clamping portion in the closed position, so that the first limit portion and the second limit portion are respectively clamped and limited when the child lock component 3 moves to two extreme positions, thereby ensuring that the relative position of the fan head 1 and the motor base 2 is more stable.

[0165] Specifically, when the child lock component 3 is in the unlocking position, the first limiting portion and the first clamping portion are clamped together to limit the movement of the child lock component 3 relative to the motor base 2. At this time, the locking pin 33 and the switch pressing block 32 are both stable in position relative to the motor base 2, which is convenient for the user to connect and fix the fan head 1 and the motor base 2 at any time without the problem of mismatching the installation position; and when the child lock component 3 is in the locking position, the second limiting portion and the second clamping portion are clamped together to limit the movement of the child lock component 3 relative to the motor base 2. At this time, the locking pin 33 and the locking port 13 of the fan head 1 can be stably locked, and at the same time, the contact state of the switch pressing block 32 and the micro switch 23 is stable, and the problem of separation of the fan head 1 and the motor base 2 and power interruption of the driving member 241 will not occur, thereby improving the safety and reliability of the structural design.

[0166] In some embodiments, Figure 2 and Figure 3As shown, one of the motor base 2 and the fan head 1 is provided with an outer plug-in ring 22 and the other is provided with an inner plug-in ring 12, and the inner plug-in ring 12 is plugged and matched with the outer plug-in ring 22. If the motor base 2 is provided with an outer plug-in ring 22, the fan head 1 is provided with an inner plug-in ring 12, and the inner plug-in ring 12 is suitable for plugging into the outer plug-in ring 22, if the motor base 2 is provided with an outer plug-in ring 22 at one end facing the fan head 1, the outer plug-in ring 22 protrudes axially at the right end of the motor base 2 to form a plug-in space in the outer plug-in ring 22, and at the same time, the fan head 1 is provided with an inner plug-in ring 12 at one end facing the motor base 2, and the inner plug-in ring 12 protrudes axially at the end of the motor base 2. Among them, the outer diameter of the inner plug-in ring 12 is smaller than the inner diameter of the outer plug-in ring 22, so that the inner plug-in ring 12 can be plugged into the outer plug-in ring 22 to realize the axial plug-in fit between the motor base 2 and the fan head 1, and a clamping structure can be set on the inner plug-in ring 12 and the outer plug-in ring 22, so that the two can be clamped through the clamping structure after plugging, so as to avoid automatic separation of the two and improve the structural stability.

[0167] Among them, a locking groove 121 is provided at the end of the inner plug-in ring 12, and a locking bevel 122 is provided in the locking groove 121. The locking bevel 122 can gradually press the outer plug-in ring 22 when the fan head 1 and the motor seat 22 are rotationally connected, so as to achieve a tight connection between the fan head 1 and the motor seat 22.

[0168] In some embodiments, Figure 6 As shown, the first limiting portion is constructed as a limiting protrusion 221, and the first clamping portion is constructed as a first hook 321. The first hook 321 is formed with a hook groove. The first hook 321 is clamped and matched with the limiting protrusion 221 and the limiting protrusion 221 is clamped into the hook groove, so that the child lock component 3 and the motor base 2 are relatively fixed in the unlocked position, ensuring that the motor base 2 can be quickly and efficiently connected and fixed when connected to the fan head 1.

[0169] Among them, a protruding limit protrusion 221 is provided in the outer plug-in ring 22 of the motor base 2, and the limit protrusion 221 protrudes radially inwardly of the motor base 2. At the same time, a first hook 321 is provided on the switch pressure block 32 of the child lock component 3. For example, the first hook 321 is located at the left end of the switch pressure block 32, and the first hook 321 is formed with a hook groove that is radially open outward. When the child lock component 3 moves toward the left unlocking position, the first hook 321 moves to a position opposite to the limit protrusion 221, so that the first hook 321 is engaged with the hook groove, so that the child lock component 3 is stably maintained in the left position, thereby realizing the locking of the child lock component 3.

[0170] And / or, the second limiting portion is constructed as a limiting block 222, and the second clamping portion is constructed as a second hook 322. The second hook 322 is clamped and limited with the limiting block 222, so that the child lock component 3 and the motor base 2 are relatively fixed in the locked position, ensuring that the motor base 2 can be effectively connected and fixed to the fan head 1, and ensuring that the installation state of the fan head 1 on the motor base 2 is more stable.

[0171] Among them, a protruding limit block 222 is provided in the outer plug-in ring 22 of the motor base 2, and the limit block 222 and the limit protrusion 221 are spaced apart and distributed in the circumferential direction of the outer plug-in ring 22, and the limit block 222 protrudes radially inwardly along the motor base 2. At the same time, a second hook 322 is provided on the switch pressure block 32 of the child lock component 3, such as 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 unlocking position, such as moving to the right, the second hook 322 moves to the right to a position opposite to the limit block 222, so that the second hook 322 and the limit block 222 are stably engaged, so that the child lock component 3 is stably maintained in the right position, thereby realizing the locking of the child lock component 3. At this time, the locking pin 33 can be stably locked with the fan head 1 to ensure the installation stability of the fan head 1 on the motor base 2.

[0172] It should be noted that, in actual design, the limit block 222 can be constructed to cooperate with the locking pin 33, such as installing the locking pin 33 in the limit block 222, so that the limit block 222 can cooperate with both the locking pin 33 and the second hook 322, thereby simplifying the structural design.

[0173] In some embodiments, Fig.11 As shown, the fan head 1 also includes a mesh cover body 14, and the fan blade 11 includes a connecting shaft 151 and a fan blade 152. The fan blade 152 is sleeved outside the connecting shaft 151, and the connecting shaft 151 is rotatably supported on the mesh cover body 14. The connecting shaft 151 is dynamically connected to the driving member 241. Among them, the mesh cover body 14 is constructed as a hollow structure, and a mounting cavity is formed in the mesh cover body 14. The fan blade 11 is rotatably installed in the mounting cavity. The fan blade 152 can be circumferentially driven with the connecting shaft 151. At the same time, the connecting shaft 151 is dynamically connected to the driving member 241, so that when the driving member 241 outputs power, it can drive the connecting shaft 151 to rotate, and then drive the fan blade 152 to rotate through the connecting shaft 151 to achieve airflow transmission.

[0174] Among them, the mesh cover body 14 is provided with hollow holes, and the hollow holes can be set to multiple, and a part of the hollow holes can be set on the rear side of the mesh cover body 14 as air inlet holes 252, and the other part of the hollow holes can be set on the front side of the mesh cover body 14 as air outlet holes 172, so that the fan blade 152 can drive the airflow from the air inlet hole 252 into the installation cavity during the rotation process, and transport it from the air outlet hole 172 to the space where the user is located.

[0175] In some embodiments, Fig.12 As shown, the mesh cover body 14 includes a first mesh cover 141 and a second mesh cover 142, and the first mesh cover 141 is detachably connected to the second mesh cover 142. In other words, the first mesh cover 141 and the second mesh cover 142 can be relatively independently disassembled, and after being connected, they jointly define a mounting cavity, and the fan blade 11 is installed between the first mesh cover 141 and the second mesh cover 142, and the fan blade 11 can be rotatably supported on 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 be connected to the motor base 2, and the second mesh cover 142 is connected to the side of the first mesh cover 141 away from the motor base 2, and the motor base 2 is located at the rear side of the fan head 1. In other words, the first mesh cover 141 can be used as a rear mesh cover, and the second mesh cover 142 can be used as a 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 diameter of the end of the mesh cover body 14. In addition, the first mesh cover 141 is constructed as an arc-shaped bowl-shaped structure, so that a movable space for the fan blades 11 to rotate is formed inside it, and the edge of the second mesh cover 142 is a mesh structure formed by multiple metal wires, which can ensure that the airflow generated when the fan blades 11 rotate is as much as possible to the air outlet formed by the second mesh cover 142, thereby improving the efficiency of the fan 100, and the first mesh cover 141 and the second mesh cover 142 are provided to avoid personal injury and short circuit caused by interference from human bodies or other objects, that is, the first mesh cover 141 and the second mesh cover 142 can prevent foreign objects from touching the internal structure of the fan 100.

[0177] Furthermore, in some embodiments, Fig.11 and Fig.12 As shown, a first bearing 1412 is provided at one end of the connecting shaft 151, such as the rear end of the connecting shaft 151 is rotatably supported on the first mesh cover 141 through the first bearing 1412, and a second bearing 1422 is provided at the other end of the connecting shaft 151, such as the front end of the connecting shaft 151 is rotatably supported on the second mesh cover 142 through 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 through the second bearing 1422, and the rear end of the connecting shaft 151 is rotatably supported on the first mesh cover 141 through the second bearing 1422.

[0178] Among them, Fig.11As shown, 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 fixed along the axial limit; and / or, the second mesh cover 142 is provided with a second connecting hole 1421, the second bearing 1422 is installed at the second connecting hole 1421, and the second mesh cover 142 and the second bearing 1422 are fixed along the axial limit, 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 fixed along the axial limit. At the same time, the second mesh cover 142 is provided with a second connecting hole 1421, the second bearing 1422 is installed at the second connecting hole 1421, and the second mesh cover 142 and the second bearing 1422 are fixed along the axial limit, or only 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 fixed along the axial limit, or only the second mesh cover 142 is provided with a second connecting hole 1421, the second bearing 1422 is installed at the second connecting hole 1421, and the second mesh cover 142 and the second bearing 1422 are fixed along the axial limit.

[0179] Specifically, in this embodiment, the first mesh cover 141 is provided with a first connecting hole 1411, and the radial size of the first connecting hole 1411 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 fixed along the axial limit, thereby limiting the axial movement of the first bearing 1412 relative to the first mesh cover 141, and at the same time, the second mesh cover 142 is provided with a second connecting hole 1421, and the radial size of the second connecting hole 1421 matches the radial size of the second bearing The radial sizes of 1422 match each other, the second bearing 1422 is installed at the second connecting hole 1421, and the second mesh cover 142 and the second bearing 1422 are fixed along the axial limit, thereby limiting the axial movement of the second bearing 1422 relative to the second mesh cover 142, so that the first bearing 1412 and the second bearing 1422 are fixed to the mesh cover body 14, and then 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 axial position can be adjusted to ensure transmission stability.

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

[0181] Alternatively, in other embodiments, the connecting shaft 151 is rotatably supported on the mesh cover body 14 through 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 body 14, thereby reducing the vibration generated by the connecting shaft 151 when transmitting power, thereby improving the smoothness of the operation of the fan 100.

[0182] In the process of power transmission, the bearing component can provide supporting force for the connecting shaft 151. At the same time, when the fan blade 152 rotates, it will generate a force on the bearing component. The force can be transmitted to the buffer structure through the bearing component, thereby weakening the effect of the force on the fan head 1, making the fan 100 run more smoothly, and the fan head 1 is detachably connected to the mesh cover body 14, making the installation and disassembly of the fan head 1 easier and more convenient.

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

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

[0185] At the same time, when the fan 100 is running, the fan blades 152 will generate a force on the connecting shaft 151 connected thereto when they rotate, and then the force will be transmitted to the bearing component through the connecting shaft 151. The bearing component is set as an independent component, so that the conduction path of the force is increased during transmission, thereby weakening the effect of the force, and a buffer pad 155 is provided between the bearing component and the mesh cover body 14. When the force is transmitted to the mesh cover body 14 through the bearing component, it can be buffered by the buffer pad 155, thereby further weakening the effect of the force and improving the smoothness of the operation of the fan 100.

[0186] In some embodiments, the fan 100 further includes: a pre-tightening structure, which is connected to the connecting shaft 151 and is 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, so that the connecting shaft 151 has a dynamic clearance control function when rotating, and the connecting shaft 151 has a suitable clearance along the axial direction, so as to avoid axial movement when the fan 100 rotates, which affects the stability of the operation of the fan 100.

[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, which is conducive to the smooth rotation of the output end of the connecting shaft 151, and then the fan blades 11 can rotate smoothly, and the vibration and friction of the connecting shaft 151 along the axial direction can be avoided, thereby achieving the effect of noise reduction, and making the power transmission between the driving member 241 and the connecting shaft 151 more efficient, thereby enhancing the use function of the fan 100, improving the service life of the product and the user experience, and having a simple structure and strong applicability.

[0188] In some embodiments, Fig.14 and Fig.15 As shown, the pre-tightening structure is constructed as an elastic bearing component 156, which includes a connected bearing portion 1561 and an elastic portion 1562. The bearing portion 1561 is relatively fixed in the fan head 1 along the axial direction, and the connecting shaft 151 is rotatably supported in the fan head 1 by the bearing portion 1561, and the elastic portion 1562 applies an elastic force toward the connecting shaft 151.

[0189] That is to say, Fig.16 As shown, the elastic bearing component 156 includes two parts, one part is the bearing part 1561, and the other part is the elastic part 1562, wherein the bearing part 1561 and the fan head 1 are relatively fixed along the axis, which can realize the fixation of the bearing part 1561 and the elastic bearing component 156, wherein the elastic bearing component 156 is constructed in a circular ring shape, and the elastic bearing component 156 is coaxially connected to the connecting shaft 151, which can make the connecting shaft 151 rotatably supported inside the fan head 1, which can realize the connection of the connecting shaft 151, and 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 portion 1562 of the pre-tightening structure will release and absorb the excess clearance to apply an elastic force to the connecting shaft 151 toward the driving member 241, thereby reducing the axial clearance of the connecting shaft 151; when the axial clearance of the connecting shaft 151 is small, the elastic portion 1562 of the pre-tightening structure will be compressed by the connecting shaft 151, thereby releasing a certain axial clearance for the connecting shaft 151, thereby increasing the axial clearance of the connecting shaft 151, and preventing the connecting shaft 151 from rotating too smoothly due to the axial clearance being too small. In this way, the axial clearance of the connecting shaft 151 can be comprehensively adjusted through the elastic portion 1562 to ensure that the axial clearance of the connecting shaft 151 is more stable.

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

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

[0193] Specifically, the sleeve 157 is axially installed inside the fan head 1, and the sleeve 157 is installed near the end of the output end of the connecting shaft 151. In actual design, the sleeve 157 can be constructed in a circular ring shape, and the sleeve 157 is sleeved outside the connecting shaft 151, and the two ends of the sleeve 157 are axially limited and fixed, so that the installation and fixation of the sleeve 157 can be achieved. Among them, the sleeve 157 can have two forms, one can be constructed to be rigid, and during the operation of the connecting shaft 151, the axial clearance of the connecting shaft 151 can be guaranteed to be a fixed value and meet the axial clearance requirement of the connecting shaft 151. The other can be constructed to be elastic, so that the sleeve 157 can be compressible. During the operation of the connecting shaft 151, the axial clearance of the connecting shaft 151 can be controlled within a certain range, thereby realizing dynamic control of the axial clearance of the connecting shaft 151 to meet the axial clearance requirement of the connecting shaft 151.

[0194] Therefore, the pre-tightening structure is set as a sleeve 157, which has a simple structure and low manufacturing cost. At the same time, the material of the sleeve 157 can be selected from two options: rigidity and elasticity, so that the pre-tightening structure is flexible and optional, and the axial clearance of the connecting shaft 151 can meet the requirements, so that the connecting shaft 151 can run smoothly.

[0195] In some embodiments, Fig.17 and Fig.18As shown, a bearing member 158 and a wind blade rope nut 154 are provided in the fan head 1, the wind blade rope nut 154 is connected to the wind blade 152 along the axial direction, the end of the connecting shaft 151 is rotatably supported in the fan head 1 through the bearing member 158, and the end of the connecting shaft 151 is rotatably supported in the fan head 1 through the bearing member 158, thereby, the wind blade 152 can be installed in the axial direction, and the end of the connecting shaft 151 is installed in the fan head 1 through the bearing member 158, so that one end of the connecting shaft 151 can be fixed; wherein, in the axial direction along the connecting shaft 151, the sleeve 157 is clamped between the wind blade rope nut 154 and the bearing member 158, thereby, the installation and fixation of the sleeve 157 can be realized, and a certain gap can be maintained between the wind blade rope nut 154 and the bearing member 158, thereby the axial gap of the connecting shaft 151 can be adjusted.

[0196] Specifically, the bearing member 158 is sleeved on the output end of the connecting shaft 151, and the bearing member 158 is connected to the inside of the fan head 1, and the bearing member 158 can be axially limited, so that the connecting shaft 151 can be rotatably supported in the fan head 1, wherein the fan blade 152 and the fan blade cable nut 154 are arranged near the driving member 241, the fan blade 152 and the fan blade cable nut 154 are sleeved outside the connecting shaft 151, the fan blade cable nut 154 is arranged near the bearing member 158, and the fan blade The nut 154 and the fan blade 152 are axially limited and fixed, so that the axial installation of the fan blade 152 can be realized, and a sleeve 157 is provided between the fan blade nut 154 and the bearing member 158. The sleeve 157 is sleeved outside the connecting shaft 151, so that the sleeve 157 can axially limit the fan blade nut 154, and the sleeve 157 is pressed against the fan blade nut 154 and the bearing member 158 respectively, so as to control the distance between the fan blade nut 154 and the bearing member 158.

[0197] In some embodiments, Fig.19 As shown, the driving member 241 is connected to the first magnetic member 243, and the fan blade 11 is connected to the second magnetic member 161. After the motor base 2 is connected to the fan head 1, the driving member 241 and the fan blade 11 are driven and connected under the action of the magnetic field of the first magnetic member 243 and the second magnetic member 161.

[0198] Among them, the driving member 241 can output power outward, and the power output end of the driving member 241 is connected to the first magnetic member 243, and the side of the fan blade 11 close to the motor base 2 is connected to the second magnetic member 161. When the second magnetic member 161 and the first magnetic member 243 are close, a magnetic field will be generated, and then an attraction force will be generated, so that the output end of the driving member 241 is driven and connected to the fan blade 11, or a repulsive force is generated between the second magnetic member 161 and the first magnetic member 243, and the repulsive force of the first magnetic member 243 on the second magnetic member 161 is used to drive the fan blade to rotate, and the design method is flexible and optional. Therefore, the driving member 241 can transmit power to the second magnetic member 161 through the first magnetic member 243, and then transmit power to the fan blade 11 through the second magnetic member 161, so that the fan blade 11 rotates, and when disassembling, the first magnetic member 243 and the second magnetic member 161 can be directly separated, so that the disassembly is more convenient, and it is convenient to disassemble and clean the fan head 1.

[0199] Furthermore, the driving member 241 is configured as a driving motor, such as Fig. 20 As shown, the first magnetic member 243 is sleeved outside the output shaft 2411 of the driving motor and cooperates with the output shaft 2411 in circumferential transmission; the fan blade 11 is provided with a connecting shaft 151, and the connecting shaft 151 is rotatably installed in the fan head 1, as shown in FIG. Fig.21 As shown, the second magnetic member 161 is sleeved outside the connecting shaft 151 and cooperates with the connecting shaft 151 in circumferential transmission.

[0200] Specifically, the driving member 241 can be set as a driving motor, and the driving motor is provided with an output shaft 2411 on the side close to the fan head 1, and the first magnetic member 243 is connected to the output shaft 2411, and the first magnetic member 243 is sleeved outside the output shaft 2411, and is relatively fixed to the output shaft 2411 in the circumferential direction, so that when the output shaft 2411 rotates to output power, the first magnetic member 243 can rotate together, and the fan head 1 is provided with a connecting shaft 151 on the side close to the driving motor, and the second magnetic member 161 is connected to the connecting shaft 151, and the second magnetic member 161 is sleeved outside the connecting shaft 151, and is relatively fixed to the connecting shaft 151 in the circumferential direction. The connecting shaft 151 is relatively fixed, so that when the second magnetic component 161 rotates, the connecting shaft 151 can rotate together. The connecting shaft 151 is rotatable relative to the fan head 1 and is fixedly connected to the fan blades 11, so that the fan blades 11 can rotate, and the first magnetic component 243 and the second magnetic component 161 generate a magnetic field, thereby generating suction, and completing the driving connection between the output shaft 2411 of the drive motor and the connecting shaft 151 of the fan blades 11. The connecting shaft 151 of the fan blades 11 is driven to rotate by the output shaft 2411 of the drive motor, thereby rotating the fan blades 11, and enabling the fan 100 to achieve blowing.

[0201] In some embodiments, the fan head 1 is suitable for being connected to the motor base 2 along a first direction, and the first direction intersects with the vertical direction. A gap adjustment portion 162 is provided at the connection between the fan head 1 and the motor base 2. The gap adjustment portion 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 relative to the motor base 2, so that the number of cleaning times of the fan head 1 can be increased to ensure that the fan 100 blows out clean air and avoid secondary air pollution. When the fan head 1 is connected to the motor base 2 and the fan 100 is in operation, the self-gravity of the fan head 1 and the force generated by the operation of the fan blades 11 cause a fitting gap to be generated between the fan head 1 and the top of the motor base 2. A gap adjustment portion 162 is provided at the connection between the fan head 1 and the motor base 2 to adjust the fitting gap to ensure the reliability of the connection between the fan head 1 and the motor base 2, and to avoid abnormal noise caused by gaps in the connection when the fan 100 is in operation, thereby reducing the user comfort.

[0203] In some embodiments, Fig. 22 and Fig.23 As shown, the gap adjustment portion 162 is constructed in a long strip shape, and the thickness of the middle portion of the gap adjustment portion 162 is greater than the rear ends of both ends, so that guide slopes are formed at both ends of the gap adjustment portion 162. The gap adjustment portion 162 can be located in the top area or the bottom area of ​​the connection.

[0204] And, the gap adjustment part 162 is made of 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 in operation will cause a matching gap to exist at the connection. The gap adjustment part 162 is arranged in the matching gap at the connection. The fan head 1's own weight and the force generated when the fan 100 is in operation will act on the gap adjustment part 162 and be transmitted through the gap adjustment part 162. The gap adjustment part 162 is set to be an elastic material, so that the force is weakened when being transmitted through the gap adjustment part 162, thereby improving the connection reliability. At the same time, the operation of the fan 100 is more stable and the generation of abnormal noise is reduced.

[0205] In some embodiments, Figure 24-Figure 27 As shown, the motor base 2 is provided with a first screw-on portion 244, and the fan head 1 is provided with a second screw-on portion 163, and the first screw-on portion 244 and the second screw-on portion 163 are suitable for being locked 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 screw-on portion 244 and the second screw-on portion 163 is provided with a screw-on rib 2441 , and the other is provided with a screw-on groove 1631 . The screw-on rib 2441 is screwed into the screw-on groove 1631 along the circumferential direction of the fan head 1 .

[0207] Specifically, a screw-on rib 2441 may be provided on the first screw-on portion 244, and a screw-on groove 1631 may be provided on the second screw-on portion 163. When the first screw-on portion 244 and the second screw-on portion 163 are screwed to a set position, the screw-on rib 2441 of the first screw-on portion 244 may be snapped into the screw-on groove 1631 of the second screw-on portion 163, so that the screw-on snap connection between the first screw-on portion 244 and the second screw-on portion 163 can be achieved. Alternatively, a screw-on groove 1631 may be provided on the first screw-on portion 244, and a screw-on rib 2441 may be provided on the second screw-on portion 163. When the first screw-on portion 244 and the second screw-on portion 163 are screwed together to the set position, the screw-on groove 1631 of the first screw-on portion 244 can be snapped into the screw-on rib 2441 of the second screw-on portion 163, so as to realize the screw-on snap-on connection between the first screw-on portion 244 and the second screw-on portion 163. Therefore, the above two settings can realize the screw-on snap-on installation of the motor base 2 and the fan head 1, and the installation of the motor base 2 and the fan head 1 is reliable, and the snap-on connection method is simple, which is convenient for the installation and connection of the motor base 2 and the fan head 1, and is convenient for later disassembly and maintenance.

[0208] In the present invention, if Figure 24-Figure 27 As shown, a screw-in rib 2441 is provided on the first screw-in portion 244, and a screw-in groove 1631 is provided on the second screw-in portion 163, that is, a screw-in rib 2441 is provided in the motor base 2, and a screw-in groove 1631 is provided at the rear end of the fan head 1, and the screw-in rib 2441 of the motor base 2 can be screwed and snapped into the screw-in groove 1631 of the fan head 1, so that the screw-in snap-in installation of the motor base 2 and the fan head 1 can be realized, and the screw-in snap-in installation process has a self-locking function, so that the installation of the motor base 2 and the fan head 1 is more reliable, and the fan head 1 can be prevented from loosening, thereby improving the safety of the use of the fan 100. At the same time, when disassembly is required, the fan head 1 is rotated in the opposite direction, so that the screw-in rib 2441 and the screw-in groove 1631 are unlocked, and the fan head 1 can be disassembled. After the above arrangement, the installation and disassembly of the fan head 1 and the motor base 2 are simpler and more convenient.

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

[0210] In some embodiments, the fan head 1 includes a first mesh cover component, fan blades 11 and a second mesh cover component, the first mesh cover component is detachably connected to the motor base 2, the second mesh cover component is detachably connected to the first mesh cover component and is suitable for defining an installation cavity, the fan blades 11 are rotatably installed in the installation cavity and are detachably connected to the second mesh cover component and / or the first mesh cover component, and the fan blades 11 are power-connected to the driving 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 by a fixing. When the fan head 1 is removed from the motor base 2, the fan blades 11 are also removed from the motor base 2, and then the fan blades 11, the first mesh cover component, and the second mesh cover component are disassembled.

[0212] Furthermore, a portion of the fan blade 11 passes through the first mesh cover component and is detachably connected to the driving member 241 in the motor base 2. Specifically, the portion of the fan blade 11 extending out of the first mesh cover component is sleeved on the driving member 241, or the driving member 241 is sleeved on the portion of the fan blade 11 extending out of the first mesh cover component, so that the fan blade 11 and the driving member 241 are conveniently connected and disassembled. After the fan blade 11, the first mesh cover component and the second mesh cover component are disassembled, the fan blade 11, the first mesh cover component and the second mesh cover component are disassembled separately, so that all the components of the entire fan head 1 are disassembled. The fan 100 of the embodiment of the present invention can be disassembled again on the basis of one disassembly, and the fan 100 can be deeply cleaned, and it is convenient for users to quickly disassemble and assemble in depth.

[0213] In some embodiments, Fig.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 limit section 1661, the limit section 1661 is located in the installation 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; wherein, 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 the first bearing 1412.

[0214] Specifically, a flange 166 is connected to one end of the fan blade 11 close to the first mesh cover component, and the fan blade 11 has a mounting hole. The flange 166 is connected to a connecting structure, which is connected to the mounting hole of the fan blade 11 and is rotatably connected relative to the flange 166, that is, the flange 166 is exposed on the left side of the mounting hole, and the flange 166 has an axially extending threaded connection section 1662 and a limiting section 1661 circumferentially connected along the threaded connection section 1662, the threaded connection section 1662 extends out of the side of the first mesh cover 141 close to the motor base 2 through the first connecting hole 1411 of the first mesh cover 141, the first locking member 167 is provided with an internal thread, and then the first locking member 167 is sleeved on the threaded connection section 1662 to connect the left end of the fan blade 11 to the first mesh cover 141, and the first mesh cover 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 a first bearing 1412 is further provided in the first connecting hole 1411, the first bearing 1412 is rotatably connected to the inside of the flange 166, and the structure connected to the driving member 241 of the motor base 2 is rotatably connected to the structure inside the flange 166 through the first bearing 1412. The embodiment of the present invention can fix the end of the fan blade 11 close to the first mesh cover 141 to the first mesh cover 141 through the flange 166, and then rotatably connect the part of the fan blade 11 with the fan blade 152 to the first mesh cover 141 through the first bearing 1412 and the structure inside the flange 166.

[0216] In some embodiments, the fan 100 further includes a locking structure, and the fan head 1 includes a first mesh cover 141 and a second mesh cover 142 that are detachably connected. Figure 28-Figure 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 portion. When the motor base 2 is connected to the first mesh cover 141, the motor base 2 pushes the push rod 164 and the limiting portion to lock.

[0217] In actual design, the fan head 1 can be rotatably connected to the motor base 2, or can be axially plugged. Generally, when the motor base 2 is circumferentially connected to the fan head 1, such as Fig.30 As shown, the pressing portion 245 provided inside the motor base 2 presses the push rod 164. When the fan head 1 and the motor base 2 need to be disassembled, the fan head 1 and the motor base 2 are first disassembled, and the pressing portion 245 is also separated from the push rod 164 at this time, and then the fan head 1 removes the first mesh cover 141 and the second mesh cover 142. It should be noted that the position of the push rod 164 and the position that cooperates with the pressing portion 245 are located inside the fan 100, such as most of the push rod 164 is located inside the fan head 1, and the position where the push rod 164 cooperates with the pressing portion 245 is located between the fan head 1 and the motor base 2, so that the relevant structure of the push rod 164 is hidden, so that the user cannot directly open the first mesh cover 141 and the second mesh cover 142 from the outside, thereby ensuring the safety of the fan head 1.

[0218] Specifically, a radially arranged and movable push rod 164 may be provided on the side of the first mesh cover 141 away from the motor base 2, and the push rod 164 may move radially relative to the first mesh cover 141. At the same time, a limiting portion is provided on the side of the second mesh cover 142 close to the first mesh cover 141, and the limiting portion is provided with a limiting hole, and the limiting hole of the limiting portion may be radially opposite to the position where the push rod 164 is provided, and the push rod 164 may be more accurately inserted into or separated from the limiting hole when moving radially, so that the push rod 164 can be connected to the second mesh cover 142 through the limiting portion, and the second mesh cover 142 is prevented from circumferential displacement.

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

[0220] Among them, Fig.28 As shown, a limit plate 143 may be provided on the first mesh cover 141, and the limit plate 143 may limit the position of the top rod 164. For example, the limit plate 143 may define a sliding hole, and the top rod 164 is passed through the sliding hole and can slide along the sliding hole. Fig.30 As shown, the pressing portion 245 may be provided with an arc-shaped pressing section 2451 , and the arc-shaped pressing section 2451 may press the ejector rod 164 to push the ejector rod 164 to move radially.

[0221] In some embodiments, Fig.29 As shown, the locking structure further includes a second elastic member 165 , which is connected between the top rod 164 and the first mesh cover 141 , and is used to apply an elastic force to the top rod 164 away from the limiting portion.

[0222] Among them, when the top rod 164 is arranged in the radial direction of the first mesh cover 141 and can move along the radial direction, the second elastic member 165 of the embodiment of the present invention can be a spring, which is arranged between the top rod 164 and the first mesh cover 141, and one end of the spring is connected to the top rod 164 and the other end is connected to the first mesh cover 141. When the top rod 164 moves, the spring will also be deformed. For example, when the top rod 164 is moved radially away from the center of the first mesh cover 141, the spring is compressed at this time, and at this time the bottom of the top 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 movement of the top rod 164.

[0223] When the motor base 2 and the fan head 1 are disassembled, the pressing portion 245 in the motor base 2 begins to separate from the position where the push rod 164 is pressed against. At this time, the push rod 164 will be pushed to return to its original state under the action of the second elastic member 165, so that the limiting portion of the second mesh cover 142 is separated 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 disassembled.

[0224] In some embodiments, Fig.32 As shown, a first heat dissipation cavity 251 for installing a driver 241 is formed in the motor base 2, that is, the motor base 2 is a hollow structure and is formed with a first heat dissipation cavity 251, so that the driver 241 can be installed in the first heat dissipation cavity 251, and a second heat dissipation cavity 171 for installing a fan blade 11 is formed in the fan head 1, that is, the fan head 1 is a hollow structure and is formed with a second heat dissipation cavity 171, so that the fan blade 11 can be installed in the second heat dissipation cavity 171, and the first heat dissipation cavity 251 and the second heat dissipation cavity 171 are connected. Among them, the first heat dissipation cavity 251 and the second heat dissipation cavity 171 can be used as a chamber for installation and as a chamber for heat dissipation, so as to realize the sharing of space for installation and heat dissipation.

[0225] like Fig.33 As shown, the motor base 2 is provided with an air inlet 252 connected to the first heat dissipation cavity 251. When the fan 100 is turned on for a long time, the driving component 241 in the motor base 2 will generate more heat. If the heat is not effectively discharged, the driving component 241 in the motor base 2 will be at a high temperature for a long time, which will reduce the life of the motor or even burn it out. In the embodiment of the present invention, the motor base 2 is provided with an air inlet 252. When the fan blades 11 are connected to the driving component 241 by power and generate heat during operation, the outside air can enter the first heat dissipation cavity 251 through the air inlet 252. The driving component 241 is located in 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 driving component 241.

[0226] In addition, the first heat dissipation cavity 251 is connected to the second heat dissipation cavity 171, and the fan head 1 is formed with 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 driving component 241 and cools down the driving component 241. A second heat dissipation cavity 171 connected to the first heat dissipation cavity 251 is provided on one side of the first heat dissipation cavity 251. Then, after the driving 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 along the air outlet 172 of the fan head 1, so as to achieve the heat dissipation of the driving component 241. At this time, the airflow that absorbs the heat of the driving component 241 is discharged through the air outlet 172. Among them, 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 driving member 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 toward the air outlet 172, so that the second heat dissipation cavity 171 forms a negative pressure, and then utilizes the negative pressure to make the external airflow pass through the air inlet 252 and the first heat dissipation cavity 251 in turn to flow into the second heat dissipation cavity 171, and in the process of flowing, the heat dissipation of the driving member 241 and the power connection position between the driving member 241 and the fan blade 11 is realized.

[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 can be connected to the first heat dissipation cavity 251. The driving member 241 is axially arranged in the motor base 2. Therefore, the airflow from the air inlet 252 to the first heat dissipation cavity 251 can contact the driving member 241 located in the first heat dissipation cavity 251 over a large area. When reaching the second heat dissipation cavity 171 inside the fan head 1, the second heat dissipation cavity 171 is used to install the fan blades 11. The fan blades 11 can be used as the airflow driving member 241 for cooling 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 the airflow in the second heat dissipation cavity 171 and accelerating the heat dissipation effect of the driving member 241.

[0228] In some embodiments, Fig.32 As shown, an installation space 255 is formed at the connection between the motor base 2 and the fan head 1, the driving member 241 is connected to the first coupling member 242, the fan blade 11 is connected to the second coupling member 153, and the first coupling member 242 and the second coupling member 153 are dynamically coupled in the installation space 255.

[0229] The motor base 2 is provided with a first heat dissipation hole 253 connecting 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 connecting the second heat dissipation cavity 171 with the installation space 255 .

[0230] Specifically, the motor base 2 is provided with an outer plug-in ring 22, which is arranged at the edge of one side of the motor base 2 close to the fan head 1, and the diameter of the outer plug-in ring 22 is larger than the diameter of the motor base 2 itself, which can facilitate the connection between the motor base 2 and the fan head 1. The fan head 1 is provided with an inner plug-in ring 12, which extends on the side of the fan head 1 toward the motor base 2, and the diameter of the outer plug-in ring 22 can be larger than the diameter of the inner plug-in ring 12. Of course, the diameter of the inner plug-in ring 12 can also be larger than the diameter of the outer plug-in ring 22, so that the motor base 2 and the fan head 1 can be plug-connected to each other, or plug-connected and rotatably connected.

[0231] Among them, the outer plug-in ring 22 is plugged into the inner plug-in ring 12 and is connected to define an installation space 255, and 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 driving member 241 is provided with an output shaft 2411, and the output shaft 2411 is provided with a first coupling member 242, and 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 in the installation space 255, and the output shaft 2411 is used to be connected to 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, and the output shaft 2411 drives the connecting shaft 151 to rotate. The connecting shaft 151 continues to drive the fan blade 11 to rotate so that the fan blade 11 drives the surrounding gas to flow, and the fan 100 can complete the blowing.

[0232] Furthermore, at the installation space 255 formed by the outer plug-in ring 22 and the inner plug-in 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, and the heat source of the driving member 241 includes: the connection between the output shaft 2411 of the motor 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 in the installation space 255, and the air flow enters the first heat dissipation cavity 251 through the air inlet hole 252 of the motor base 2, and continues to reach the installation space 255 through the first heat dissipation cavity 251, so that the heat source concentrated in the installation space 255 can be dissipated, thereby avoiding the temperature of the connection between the first coupling member 242 and the second coupling member 153 from being too high, thereby extending the service life.

[0233] In some embodiments, the first coupling member 242 is detachably connected to the output shaft 2411 of the driving member 241 via a connecting member, so as to facilitate installation and removal of the first coupling member 242 .

[0234] Furthermore, the fan blades 11 arranged in the fan head 1 can be power-coupled through the first coupling member 242 fixedly connected to the output shaft 2411, so that the fan 100 generates windflow. When the first coupling member 242 needs maintenance or replacement, the fan head 1 is removed from the connection with the motor base 2 to expose the first coupling member 242, and then the connecting member can be taken out, so that the first coupling member 242 is movable relative to the output shaft 2411, so that the first coupling member 242 can be removed to complete the disassembly of the first coupling member 242. 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 connecting member, and then the fan head 1 is fixedly connected to the motor base 2 to complete the installation of the first coupling member 242, saving the maintenance and replacement time of the first coupling member 242.

[0235] In some embodiments, Fig.32 and Fig.37 As shown, the fan 100 further includes a protective cover 254, which is mounted on the end surface of the motor base 2 facing the fan head 1, and the protective cover 254 is arranged on the end surface 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 241 is greater than the set distance. It should be noted that the electric drive 241 can be set as a drive motor, that is, the electric drive 241 is a live part, and when the user disassembles and separates 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 occurs, and then when the user connects the first coupling member 242 and the second coupling member 153, it is easy to cause the current on the electric drive 241 to be directed to the user.

[0236] In the present invention, the end face of the motor base 2 facing the fan head 1 is shielded by the protective cover 254, so that the protective cover 254 can shield the electric driver 241, thereby preventing the electric driver 241 from being exposed at the end of the motor base 2 facing the fan head 1, and preventing the user's hand from directly contacting the electric driver 241. At the same time, the protective cover 254 can increase the distance between the electric driver 241 and the user's hand, thereby increasing the creepage distance between the electric driver 241 and the user's hand, thereby preventing a large amount of current from being directed to the user and improving the user's safety. It should be noted that the set distance can be set according to safety regulations, so that after the protective cover 254 is installed on the motor base 2, the creepage distance is increased, and the user will not encounter safety problems due to creepage after touching the end of the motor base 2.

[0237] like Fig.37As shown, the protective cover plate 254 is provided with a middle heat dissipation hole 2541, and the middle heat dissipation hole 2541 is connected between 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 to the second heat dissipation hole 173 through the middle heat dissipation hole 2541 to enter the second heat dissipation cavity 171, thereby facilitating the airflow from the first heat dissipation hole 253 to the second heat dissipation hole 173. In other words, the provision of the protective cover plate 254 will not affect the heat dissipation inside the electric drive 241, ensuring that the heat dissipation inside the electric drive 241 can still be effectively performed.

[0238] In some embodiments, there are multiple first heat dissipation holes 253, multiple middle heat dissipation holes 2541 and multiple second heat dissipation holes 173, and the multiple first heat dissipation holes 253, multiple middle heat dissipation holes 2541 and multiple second heat dissipation holes 173 are distributed one by one along the axial direction of the electric driving component 241, so that the first heat dissipation holes 253, the middle heat dissipation holes 2541 and the second heat dissipation holes 173 form multiple groups of heat dissipation channels, thereby facilitating increasing the air flow between the air inlet 252 and the air outlet 172, and enhancing the effective heat dissipation of the electric driving component 241 and the matching parts of the first coupling component 242 and the second coupling component 153.

[0239] In some embodiments, Fig.38 and Fig.39 As shown, one of the motor base 2 and the fan head 1 is provided with a movable active structure 261, and the active structure 261 is provided with a third clamping portion 262. The other of the motor base 2 and the fan head 1 is provided with a fourth clamping portion 181. The third clamping portion 262 is clamped and connected with the fourth clamping portion 181, and the third clamping portion 262 and the fourth clamping portion 181 are suitable for unlocking when the active structure 261 is compressed or pulled.

[0240] That is to say, the active structure 261 can be arranged on the motor base 2 or on the fan head 1. When the active structure 261 is arranged on the motor base 2, the third clamping portion 262 is arranged on the motor base 2, and the fourth clamping portion 181 is arranged on the fan head 1. Conversely, when the active structure 261 is arranged on the fan head 1, the third clamping portion 262 is arranged on the fan head 1, and the fourth clamping portion 181 is arranged on the motor base 2, the connection between the motor base 2 and the fan head 1 can be achieved through any of the above two design methods.

[0241] Furthermore, if Fig.39As shown, the motor base 2 and the fan head 1 are suitable for being connected by the third clamping part 262 and the fourth clamping part 181, that is, the fan head 1 can be connected to the motor base 2 by means of clamping, and the clamping connection method is simple and easy to install, and the active structure 261 is configured to unlock the third clamping part 262 and the fourth clamping part 181 when under compression or tension, that is, when the active structure 261 is pressed or pulled up, the active structure 261 moves, and the third clamping part 262 and the fourth clamping part 181 can be dislocated and unlocked, and the entire fan head 1 can be removed. The entire disassembled fan head 1 is not electrified. This method of disassembling the fan head 1 is simple and easy, and it is convenient to disassemble and clean the entire fan head 1.

[0242] Therefore, an active structure 261 is provided on the motor base 2 or the fan head 1, which can make the installation and disassembly of the fan head 1 easier and more convenient, and the fan head 1 can be independently disassembled relative to the motor base 2, so that the user can remove the fan head 1 separately, and it is easy to clean the fan head 1, thereby increasing the number of cleaning times of the fan head 1 to ensure that the fan 100 blows out clean air, so that the user experience is better.

[0243] In some embodiments, Fig.39 As shown, the active structure 261 is configured to be pressable along the second direction, and one of the motor base 2 and the fan head 1 is also provided with an elastic reset member 265, and the elastic reset member 265 is used to elastically pre-tighten the active structure 261 along the third direction, and 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, and the elastic reset member 265 is arranged opposite to the active structure 261, and the active structure 261 can be pressed along the second direction, and the elastic reset member 265 can generate an elastic force along the third direction to elastically pre-tighten the active structure 261, wherein the second direction is opposite to the third direction, so that the third clamping portion 262 is firmly clamped with the fourth clamping portion 181, so that the fan head 1 can be 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 arranged inside the motor base 2, the elastic reset member 265 is arranged at the lower end of the motor base 2, and the active structure 261 is located at the upper end of the elastic reset member 265. After the fan head 1 is connected to the motor base 2, the third clamping portion 262 of the active structure 261 is clamped into the fourth clamping portion 181, and the elastic reset member 265 generates an upward elastic force, which can make the third clamping portion 262 and the fourth clamping portion 181 clamped, that is, the fan head 1 is firmly installed. Therefore, by arranging the active structure 261 and the elastic reset member 265 opposite to each other, the active structure 261 and the elastic reset member 265 can interact with each other, so that the installation of the fan head 1 is more secure and the fan head 1 is convenient to disassemble.

[0245] Among them, Fig.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 return member 265 is constructed as a spring, and one end of the elastic return member 265 is sleeved on the limiting boss 263 and the other end extends into the limiting groove 264.

[0246] Specifically, the limiting boss 263 is arranged at the lower end of the active structure 261, and the limiting groove 264 can be arranged on the motor base 2 or on the fan head 1, wherein the limiting boss 263 and the limiting groove 264 are arranged opposite to each other, one end of the elastic return member 265 is sleeved on the limiting boss 263, and the other end extends into the limiting groove 264, so that the installation of the elastic return member 265 can be completed. The elastic return member 265 is installed between the limiting groove 264 and the limiting boss 263, so that the two ends of the elastic return member 265 can be limited and fixed, so that the elastic return member 265 is firmly installed.

[0247] The limiting groove 264 can be arranged on the motor base 2 and is located at the bottom of the active structure 261, and the limiting groove 264 is located below the limiting boss 263. The limiting boss 263 is constructed as a cylindrical shape, and the limiting groove 264 is constructed as a circular groove. 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. In this way, the elastic reset member 265 can be better installed in the limiting boss 263 and the limiting groove 264, and the limiting of the elastic reset member 265 is reliable. Among them, the elastic reset member 265 can be a spring. After the fan head 1 is pushed flat into the motor base 2, due to the gravity of the fan head 1 itself, the fourth clamping portion 181 is clamped into the third clamping portion 262, and self-locking can be achieved. At the same time, the fourth clamping portion 181 presses the third clamping portion 262 downward to 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, so that the installation of the fan head 1 is firm and reliable.

[0248] Among them, since the elastic reset member 265 is mainly used to provide elastic force for the active structure 261, the installation structure of the elastic reset member 265 can be designed according to actual conditions. 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, so as to realize the connection between the elastic reset member 265 and the active structure 261, and then the elastic reset member 265 can apply elastic force to the active structure 261.

[0249] In some embodiments, Fig.40 and Fig.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 , and the locking member 266 is suitable for locking with the locking groove 182 when the motor base 2 and the fan head 1 are connected.

[0250] That is to say, a retractable locking piece 266 can be set on the motor base 2, and a locking groove 182 can be set on the fan head 1, or a retractable locking piece 266 can be set on the fan head 1, and a locking groove 182 can be set on the motor base 2. Through any of the above two design methods, the plug-in connection between the motor base 2 and the fan head 1 can be achieved.

[0251] Furthermore, the motor base 2 and the fan head 1 are suitable for being locked with the locking piece 266 and the locking groove 182 after being plugged in. That is, after the motor base 2 and the fan head 1 are plugged in, the locking piece 266 corresponding to the motor base 2 and the fan head 1 can be plugged into the locking groove 182 to achieve locking between the motor base 2 and the fan head 1. That is, 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 plugged in and locked, and the locking effect is good and effortless.

[0252] During specific installation, the motor base 2 is provided with a retractable locking member 266, which is arranged on the side of the motor base 2 facing the fan head 1, and the fan head 1 is provided with a locking groove 182, which is arranged on the side of the fan head 1 facing the motor base 2. During specific installation, when the fan head 1 is pushed horizontally into the motor base 2, the locking piece 266 is pushed to be inserted into the locking groove 182 for locking, so that the connection between the fan head 1 and the motor base 2 is completed. After the locking piece 266 is locked with the locking groove 182, the locking piece 266 can lock the fan head 1 in the circumferential and axial directions, so that the locking effect is better. During specific disassembly, the fan head 1 can be directly pulled horizontally in the opposite direction, and the locking groove 182 can be disengaged from the locking piece 266 through the pulling force, so that the entire fan head 1 can be removed, so that the fan head 1 can be independently disassembled, and the installation and disassembly steps are simple, convenient, and effortless, which can facilitate the cleaning of the entire fan head 1, and can ensure that clean air is blown out when the fan 100 is used, so as to improve the user experience.

[0253] Therefore, by setting the fan head 1 to be independently detachable, the number of times the fan head 1 is cleaned can be increased. The user can regularly remove the fan head 1 every week for flushing. Dust is not easily accumulated inside the fan head 1, and it is convenient to clean.

[0254] In some embodiments, Fig.42 and Fig.43 As shown, the fan head 1 is plug-connected with the motor base 2, and one of the fan head 1 and the motor base 2 is installed with a rotatable second locking member 267, and 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] That is to say, 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 be locked with the fan head 1 or with the motor base 2 after rotation. When the second locking member 267 is installed on the fan head 1, the second locking member 267 can be locked with the motor base 2 after rotation; conversely, when the second locking member 267 is installed on the motor base 2, the second locking member 267 can be locked with the fan head 1 after rotation. Through the above two design methods, the connection and locking of the motor base 2 and the fan head 1 can be achieved.

[0256] Furthermore, the fan head 1 is suitable for being plugged and connected with the motor base 2, that is, the fan head 1 can be connected to the motor base 2 by plugging, and the plugging connection method is simple and easy to install, and the second locking member 267 is configured to lock the fan head 1 and the motor base 2 by turning in, that is, when the second locking member 267 is rotated into the fan head 1 or the motor base 2 in a certain direction, the other of the fan head 1 or the motor base 2 can be locked, thereby limiting the relative displacement between the fan head 1 and the motor base 2, such as in a clockwise direction. When the second locking member 267 is rotated out of the fan head 1 or the motor base 2 in a certain direction, the other of the fan head 1 or the motor base 2 can be unlocked, such as in a counterclockwise direction, thereby separating the fan head 1 from the motor base 2 to achieve 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 it is convenient to disassemble and clean 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 are more convenient and effortless, and the fan head 1 can be easily cleaned to ensure that clean air is blown out when the fan 100 is used, so as to improve the user experience. At the same time, the second locking member 267 is used to relatively fix the position of the fan head 1 and the motor base 2 to ensure the firmness of the connection.

[0258] Among them, Fig.43 As shown, the locking member 267 includes a twisting portion 2671 and a locking portion 2672. The locking portion 2672 is penetrated by the outer plug-in ring 22 and is threadedly connected to the outer plug-in ring 22. The twisting portion 2671 is connected to the locking portion 2672 and extends to the outside of the outer plug-in ring 22. The locking portion 2672 is suitable for pressing against the inner plug-in 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 suitable for being compressed by the buffer portion after being connected. In actual design, the fan head 1 and the motor base 2 can be connected by threaded rotation or axial clamping. Regardless of the connection method, when the fan head 1 and the motor base 2 are connected, the buffer portion provided in any one of the fan head 1 and the motor base 2 has a certain buffer force between the fan head 1 and the motor base 2. 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 is pressed and buffered. 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, so that there is an elastic extrusion space between the fan head 1 and the motor base 2, absorbing the vibration problem caused by the rotating parts such as the motor or the fan blade 11, and can also make the assembly gap well balanced, with the effect of pre-tightening and buffering. Among them, the buffer portion can be a component made of soft materials such as silicone, a spring, or a bending structure that can be deformed by extrusion.

[0260] In some embodiments, Figure 44-Figure 47 As shown, one of the fan head 1 and the motor base 2 is provided with a first buffer portion 183 and the other is provided with a second buffer portion 268, and the first buffer portion 183 and the second buffer portion 268 are suitable for being pressed toward each other when the fan head 1 is connected to the motor base 2. That is, the buffer portion includes the first buffer portion 183 and the second buffer portion 268, the first buffer portion 183 can be provided on the fan head 1, and the second buffer portion 268 can be provided on the motor base 2. Of course, the first buffer portion 183 can also be provided on the motor base 2, and the second buffer portion 268 can be provided on the fan head 1, and both the first buffer portion 183 and the second buffer portion 268 can be provided on the surface where the motor base 2 and the fan head 1 are connected to each other. 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 tightly after the fan head 1 is connected to the motor base 2.

[0261] In practice, the structures of the first buffer 183 and the second buffer 268 can be the same or different, as long as the fan head 1 and the motor base 2 can have a certain buffering and pre-tightening effect through the first buffer 183 and the second buffer 268 after they are installed. Furthermore, the materials used by the first buffer 183 and the second buffer 268 can be the same or different, for example, the first buffer 183 and the second buffer 268 can be elastic materials at the same time, or at least one of them can be elastic materials. When one of the first buffer 183 and the second buffer 268 is an elastic material and the other is a hard material, the material of the motor base 2 or the fan head 1 itself can be used as the first buffer 183 or the second buffer 268, and the elastic material of one side can be used as a buffer force after the connection; when the first buffer 183 and the second buffer 268 are both elastic materials, the elastic materials of both sides can be used as a buffer force, so that after the fan head 1 and the motor base 2 are connected, they can be elastically pressed together, which has the effect of buffering and absorbing vibration.

[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 suitable for being fixed by suction through a magnetic attraction structure. Therefore, when the motor base 2 and the fan head 1 are connected, they are first circumferentially limited by the positioning structure, wherein the positioning structure can be set at the connection between the motor base 2 and the fan head 1, and the specific positioning structure can be adopted, such as a groove and a protrusion match, and the positioning structure can facilitate the motor base 2 and the fan head 1 to maintain alignment when connected, so that the two can be quickly connected, and at the same time, the circumferential relative displacement when the motor base 2 and the fan head 1 are connected can be avoided, and the circumferential displacement change of the motor base 2 and the fan head 1 due to vibration can be prevented; the magnetic attraction structure is set between the connection between the motor base 2 and the fan head 1, and when the motor base 2 and the fan head 1 are first positioned by the positioning structure, they are then fixed by suction through the magnetic attraction structure located between the motor base 2 and the fan head 1.

[0263] As a result, the connecting parts of the motor base 2 and the fan head 1 are aligned and then connected by the magnetic attraction structure. The overall installation is convenient and fast, and the fan head 1 and the motor base 2 can be independently disassembled and installed, which is convenient for effective cleaning of the fan 100 and saves time.

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

[0265] In practice, the structures of the first magnetic attraction portion 269 and the second magnetic attraction portion 184 can be the same or different, as long as the first magnetic attraction portion 269 and the second magnetic attraction portion 184 can be attracted to and lock the fan head 1. The first magnetic attraction portion 269 and the second magnetic attraction portion 184 can be radially distributed along the position between the inner plug-in ring 12 and the outer plug-in ring 22, that is, radially distributed along the inner plug-in ring 12 and radially distributed along the outer plug-in ring 22, and the positioning structure is also arranged at the connection between the fan head 1 and the motor base 2, so that the positioning structure and the magnetic attraction structure can be effectively combined. The positioning structure and the magnetic attraction structure are both arranged in the limited connection space between the fan head 1 and the motor base 2, so that the first magnetic attraction portion 269 and the second magnetic attraction portion 184 can be effectively locked and positioned.

[0266] Among them, one of the first magnetic attraction part 269 and the second magnetic attraction part 184 is a magnet and the other is made of magnetic metal material; or, the first magnetic attraction part 269 and the second magnetic attraction part 184 are both magnets, and different methods are used to ensure that the first magnetic attraction part 269 and the second magnetic attraction part 184 can be attracted together.

[0267] The present invention also provides an assembly method of the fan 100 .

[0268] The assembly method of the fan 100 according to the embodiment of the present invention is applicable to the fan 100 described in any of the above embodiments, and as Fig.50 As shown, the assembly method includes:

[0269] S1: Install the driving member 241 in the motor base 2 to form a first independent body, whereby the motor base 2 and its internal structure can be used as an independent whole;

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

[0271] S3: Connect and lock the first independent body with the second independent body. Thus, when the fan head 1 and the motor base 2 are connected and fixed, the first independent body and the second independent body can be connected and locked, so that the fan head 1 can be stably installed on the motor base 2, and the connection and installation of the two can be achieved. Among them, the fan head 1 as an independent whole can be disassembled and replaced separately relative to the motor base 2, which is beneficial for users to increase the number of cleaning times of the fan head 1. For example, users can regularly remove the fan head 1 every week for washing. As the number of cleanings increases, dust is not easy to accumulate inside the fan head 1, and it only needs to be rinsed with a faucet when cleaning, which is very convenient.

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

[0273] S21: driving the child lock component 3 to move relative to the motor base 2, and locking the child lock component 3 with the fan head 1, while triggering the micro switch 23 to turn on the power of the driving member 241. Thus, in actual use, the user connects the motor base 2 with the fan head 1. After the connection, the child lock component 3 can be driven to move relative to the motor base 2 so that the child lock component 3 locks the motor base 2 with the fan head 1, thereby preventing the fan head 1 and the motor base 2 from being automatically separated during the use of the fan 100. At the same time, the child lock component 3 pushes the micro switch 23 to operate, so that the driving member 241 is turned on, thereby realizing the driving of the fan blades 11. When the user disassembles the fan head 1, the child lock component 3 can be operated first to unlock the fan head 1 relative to the motor base 2, so as to facilitate the separate disassembly of the fan head 1. At the same time, the micro switch 23 is no longer reset by the force of the child lock component 3, thereby disconnecting the power of the driving member 241, and realizing the stopping of the rotation of the fan blades 11.

[0274] That is to say, when the user disassembles the fan head 1 relative to the motor base 2, the child lock component 3 unlocks the fan head 1 relative to the motor base 2, and at the same time, through the action of the micro switch 23, the driving member 241 no longer outputs the driving force, so that the driving member 241 is in a state of stopping outputting power during the disassembly of the fan head 1, thereby preventing the active action of the driving member 241 from causing damage to the user when the user disassembles the fan head 1, and when the driving member 241 drives the fan blades 11 to rotate, the fan head 1 and the motor base 2 are already in a stable connected state, which can provide better protection for child users and improve the safety of the use of the fan 100.

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

[0276] S22: driving the sliding paddle 31 to slide relative to the motor base 2, and the sliding paddle 31 pushes the locking pin 33 to lock with the fan head 1 during the movement. The sliding paddle 31 is an active part, and the sliding paddle 31 can be at least partially exposed outside the motor base 2, so that the user can actively operate the sliding paddle 31, so that the user can flexibly operate the sliding paddle 31 according to his own wishes to drive the locking pin 33. The locking pin 33 is a driven part. When the sliding paddle 31 moves, the locking pin 33 moves relative to the motor base 2 under the action of the sliding paddle 31, and the locking pin 33 has a locking position and an unlocking position relative to the motor base 2. When the locking pin 33 is in the locking position, the locking pin 33 can be limited and fixed with the fan head 1 to lock the fan head 1 relative to the motor base 2, that is, at this time, the user cannot disassemble the fan head 1 relative to the motor base 2, and when the locking pin 33 is in the unlocking position, the fan head 1 is unlocked relative to the motor base 2, and the user can flexibly disassemble the fan head 1.

[0277] Furthermore, in the specific structure, the motor base 2 can be rotatably engaged with the fan head 1, that is, the fan head 1 can be rotatably installed on the motor base 2, and a locking hole 13 can be provided on the fan head 1. After the fan head 1 is rotated into position relative to the motor base 2, the locking pin 33 can extend into the locking hole 13 and limit the reverse rotation of the fan head 1 relative to the motor base 2, thereby preventing the fan head 1 from automatically rotating and disassembling relative to the motor base 2. During disassembly, the locking pin 33 can be driven to extend from the locking hole 13 by the sliding paddle 31. At this time, the locking pin 33 no longer has a circumferential limiting effect on the fan head 1, thereby allowing the fan head 1 to be disassembled relative to the motor base 2. The structure is simple, which is conducive to the flexible locking and unlocking of the fan head 1 and the motor base 2.

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

[0279] S23: The sliding paddle 31 pushes the locking pin 33 during the movement to trigger the micro switch 23 to turn on, so that the power of the driving member 241 is turned on; it should be noted that the micro switch 23 is configured as a normally-off switch at this time, in other words, the micro switch 23 is in an off state when not acted upon by an external force. The child lock component 3 can contact the micro switch 23 during the movement, and in particular, when designed, the sliding paddle 31 can simultaneously trigger the micro switch 23 to turn on when driving the locking pin 33 to lock the fan head 1.

[0280] Or, S24: the sliding paddle 31 drives the switch pressing block 32 to release the pressing spring piece 231 of the micro switch 23 during the movement, so that the power of the driving member 241 is turned on. It should be noted that at this time, the micro switch 23 is constructed as a normally-on switch, and is provided with a pressing spring piece 231, wherein the pressing spring piece 231 is located on one side of the micro switch 23, one end of the pressing spring piece 231 is connected to the micro switch 23 and the other end is spaced from the micro switch 23, wherein when the pressing spring piece 231 is in a naturally extended state, the micro switch 23 is in a connected state, that is, the driving member 241 can output a driving force, and when the pressing spring piece 231 is squeezed and deformed toward the micro switch 23 by an external force, the micro switch 23 is switched to a disconnected state.

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

[0282] S31: Insert the output shaft 2411 of the driving member 241 through the mounting hole of the fan blade 11 and plug 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 allow the fastener to limit the axial position of the fan blade 11.

[0284] Thus, by setting the fan head 1 to be independently detachable, wherein, after actual installation, the output shaft 2411 can be connected and fixed by fasteners, and the fasteners can axially limit the fan blades 11, so as to maintain 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. Among them, the fasteners can be threaded structures such as nuts. During the disassembly process, the fasteners can be unscrewed from the output shaft 2411, and other structural parts can be further easily disassembled. The disassembly structure is simple and the disassembly process is easy to implement, which is conducive to users increasing the number of cleaning times of the fan head 1. For example, users can regularly remove the fan head 1 every week for flushing.
