[0044] Fans are widely used in daily life and industrial production. Its working principle is to drive the fan blades to rotate through the motor, so that the surrounding air flows faster, thereby generating wind power, achieving the purpose of cooling down or air circulation.

[0045] A fan usually includes a connected fan head and a drive assembly. The fan head mainly includes a front mesh, a rear mesh and fan blades. When cleaning existing fan products, the front mesh, rear mesh and fan blades need to be removed from the drive assembly one by one, which makes the disassembly more complicated.

[0046] Therefore, in order to solve the technical problem that the front net, rear net and fan blades of existing fan products need to be disassembled one by one when cleaning, resulting in complicated disassembly, the present application provides a fan that can improve the convenience of fan disassembly, thereby improving the convenience and efficiency of fan cleaning. Please refer to the following embodiments for details.

[0047] See also Figure 1-Figure 15 The fan 1 provided in the present application includes a transmission module 10 , a machine head 20 , and a fan head 30 .

[0048] The head 20 includes a motor 210 and a head housing 220 . The motor 210 is installed in the head housing 220 . The motor 210 has an output shaft 211 .

[0049] The fan head 30 includes a mesh housing 32 and fan blades 31, wherein the fan blades 31 are installed in the mesh housing 32; the mesh housing 32 is detachably connected to the head housing 220, and the mesh housing 32 is provided with a movable locking mechanism 300, which can be selectively in a locked state or an unlocked state.

[0050] The transmission module 10 is installed on the mesh cover assembly and connected to the fan blades 31. When the mesh cover shell 32 is connected to the head shell 220 and the locking mechanism 300 is in a locked state, the mesh cover shell 32 can be connected and fixed to the head shell 220, and the output shaft 211 is coupled to the transmission module 10 to drive the fan blades 31 to rotate; when the locking mechanism 300 is in an unlocked state, the mesh cover shell 32 can be separated from the head shell 220, and the output shaft 211 is separated from the transmission module 10.

[0051] In this way, the fan 1 is configured to be a detachably connected head 20, a fan head 30 and a transmission module 10, wherein the fan head 30 includes a mesh housing 32 and a fan blade 31, the fan blade 31 is installed in the mesh housing 32, the mesh housing 32 is detachably connected to the head housing 220 of the head 20, the transmission module 10 is installed in the mesh housing assembly and connected to the fan blade 31, and since the mesh housing 32 is provided with a movable locking mechanism 300, and the locking mechanism 300 can be selectively in a locked state or an unlocked state, therefore, when the locking mechanism 300 is in When in the unlocked state, the mesh cover shell 32 can be separated from the head shell 220, and the output shaft 211 is separated from the transmission module 10. That is, when the fan 1 needs to be disassembled, the fan head 30 can be separated from the drive assembly by simply moving the locking mechanism 300 to the unlocked state. That is, the fan head 30 can be quickly disassembled from the drive assembly as a whole in one step, without the need for the complicated process of disassembling each component of the fan head 30 (such as the front mesh, fan blades, and rear mesh) one by one as in the prior art, thereby helping to improve the convenience and efficiency of disassembling the fan head 30.

[0052] In addition, when the mesh cover shell 32 is connected to the head shell 220 and the locking mechanism 300 is in a locked state, the mesh cover shell 32 can be connected and fixed to the head shell 220, and the output shaft 211 is coupled to the transmission module 10 to drive the fan blades 31 to rotate, and through the movable locking mechanism 300, the locking mechanism 300 is in a locked state to make the connection between the fan head 30 and the head 20 more stable, thereby improving the safety of the use of the fan 1 and helping to reduce safety risks caused by loose or falling parts.

[0053] In some embodiments, the mesh cover shell 32 can be detachably connected to the head shell 220 by means of snaps, screws, plug-ins, etc.

[0054] In some embodiments, the locking mechanism 300 can be installed on the mesh housing 32 by rotating, sliding, moving, etc.

[0055] In some embodiments, the locking mechanism 300 includes a locking member 310, which is movably mounted on the mesh cover shell 32, and the head shell 220 is provided with a locking slot 221. When the mesh cover shell 32 is connected to the head shell 220 and the locking mechanism 300 is in a locked state, the locking member 310 is partially located in the locking slot 221; when the locking mechanism 300 is in an unlocked state, the locking member 310 is located outside the locking slot 221, and the mesh cover shell 32 can be separated from the head shell 220.

[0056] Since the locking piece 310 is movably mounted on the mesh cover shell 32, when the mesh cover shell 32 is connected to the head shell 220, the locking piece 310 can be moved in the direction of the locking groove 221 so that part of the locking piece 310 is located in the locking groove 221 and plugged into the locking groove 221, thereby ensuring a stable connection between the wind mesh cover shell 32 and the head shell 220; and when the mesh cover shell 32 needs to be disassembled from the head shell 220, the locking piece 310 is moved in the opposite direction of the locking groove 221 so that the locking piece 310 is completely moved out of the locking groove 221, thereby driving the mesh cover shell 32 to move in the opposite direction of the locking groove 221, thereby separating from the head shell 220, thereby realizing the separation of the fan head 30 from the head 20, and improving the convenience of disassembling the fan head 30.

[0057] In some embodiments, the locking mechanism 300 further includes an elastic member 320 and a connecting member 330 ; the connecting member 330 is fixed to the mesh cover shell 32 , the locking member 310 is installed between the connecting member 330 and the mesh cover shell 32 , and the elastic member 320 is installed between the connecting member 330 and the locking member 310 .

[0058] In some embodiments, the elastic member 320 may also be installed between the mesh housing 32 and the locking member 310 .

[0059] The length direction of the elastic member 320 extends along the radial direction of the nose 20 .

[0060] In some embodiments, the connecting member 330 may be fixedly connected to the fan head 30 by means of screws or the like.

[0061] In some embodiments, the elastic member 320 may be a spring or other materials or elements having elastic properties.

[0062] Illustratively, when the locking member 310 is moved in the opposite direction of the locking groove 221, the elastic member 320 is compressed, so that the locking member 310 can be moved out of the locking groove 221, thereby driving the fan head 30 to separate from the driving assembly 100; and when the locking member 310 is released, the locking member 310 is reset under the action of the elastic member 320, and the locking mechanism 300 is in a locked state, that is, part of the locking member 310 is located in the locking groove 221 and is plugged into the locking groove 221.

[0063] In this way, by setting the elastic member 320, the user only needs to move the locking member 310 to the unlocked state. After releasing the elastic member 320, the locking member 310 can automatically restore the locking member 310 to the locked state. The user does not need to manually reset the locking member 310, which simplifies the operation process of the locking member 310 and makes the assembly and disassembly of the fan 10 easier and faster.

[0064] In addition, the elastic member 320 can ensure the stable position of the locking member 310 in the locked state, which helps to reduce the possibility of accidental unlocking, thereby reducing the risk of accidental unlocking of the fan 10 due to vibration or collision during use, thereby improving the safety of the use of the fan 10.

[0065] In some embodiments, the transmission module 10 includes a transmission body 100 and a transmission shaft 130, the transmission shaft 130 is rotatably inserted into the transmission body 100, and the transmission body 100 is detachably connected to the mesh cover shell 32; when the transmission body 100 is connected to the mesh cover shell 32, one end of the transmission shaft 130 is inserted into the fan blade 31; when the mesh cover shell 32 is connected to the head shell 220, the output shaft 211 is coupled and connected to the other end of the transmission shaft 130.

[0066] Since the transmission body 100 on the transmission module 10 is detachably connected to the mesh housing 32, when the mesh housing 32 is connected to the head housing 220, the output shaft 211 is coupled and connected to the other end of the transmission shaft 130, that is, the transmission module 10 is used as a connecting bridge between the head 20 and the fan head 30. In this way, the fan blades 31 in the fan head 30 can be separated from the transmission module 10 and the output shaft 211 of the motor 210, thereby improving the existing fan 1 in which the fan blades cooperate with the motor shaft and the motor shaft pin through the shaft connector integrated with the fan blades 31, so that the fan head 30 can be disassembled from the drive assembly as a whole, avoiding the complicated process of disassembling each component included in the fan head 30 from the drive assembly one by one, thereby improving the convenience and efficiency of disassembling the fan 1.

[0067] In some embodiments, the transmission body 100 includes a transmission housing 110, a bearing 120, a first sealing ring 101 and a second sealing ring 102. The transmission housing 110 is provided with a receiving space, a first connecting hole 140 and a second connecting hole 150. The first connecting hole 140 and the second connecting hole 150 are both connected to the receiving space and are located at opposite sides of the transmission housing 110. The transmission shaft 130 is rotatably connected to the transmission housing 110 through the bearing 120 and is passed through the first connecting hole 140 and the second connecting hole 150.

[0068] The first sealing ring 101 is sleeved on the outer circumference of the transmission shaft 130 and abuts between the transmission housing 110 and the transmission shaft 130 to block the first connecting hole 140. The second sealing ring 102 is sleeved on the outer circumference of the transmission shaft 130 and abuts between the transmission housing 110 and the transmission shaft 130 to block the second connecting hole 150.

[0069] In this way, by introducing the first sealing ring 101 which is sleeved on the outer periphery of the transmission shaft 130 and abuts between the transmission housing 110 and the transmission shaft 130, and the second sealing ring 102 which is sleeved on the outer periphery of the transmission shaft 130 and abuts between the transmission housing 110 and the transmission shaft 130, the first sealing ring 101 and the second sealing ring 102 are respectively blocked with the first connecting hole 140 and the second connecting hole 150 to form a double seal, which effectively prevents impurities such as dust and water from entering the interior of the transmission module 10, reduces the damage of impurities such as dust and water to the internal bearing 120 of the transmission module 10, and thereby extends the service life of the transmission module 10.

[0070] In some embodiments, the transmission housing 110 includes a first sub-shell 111 and a second sub-shell 112, the second sub-shell 112 is detachably connected to the first sub-shell 111, the first sub-shell 111 and the second sub-shell 112 together enclose a receiving space, the first connecting hole 140 is located in the first sub-shell 111, and the second connecting hole 150 is located in the second sub-shell 112.

[0071] The first sub-shell 111 can be detachably connected to the second sub-shell 112 by means of threaded connection, snap connection, magnetic connection, or latch connection.

[0072] In this way, the detachable connection between the first sub-shell 111 and the second sub-shell 112 simplifies the assembly process and improves the assembly efficiency of the transmission module 10 .

[0073] For example, in some embodiments, the first sub-shell 111 is provided with a first snap-fit ​​structure, and the second sub-shell 112 is provided with a second snap-fit ​​structure, and the second snap-fit ​​structure can be snap-fitted and fixed with the first snap-fit ​​structure.

[0074] The first buckle structure may be a buckle protrusion, the second buckle structure may be a buckle slot, and the buckle may be embedded in the buckle slot.

[0075] Thus, the buckle connection method can be connected by simply pressing or rotating without complicated tools or operation steps. Secondly, the buckle connection is more secure and not easy to loosen, thus ensuring the stability and reliability of the transmission module 10.

[0076] Since the transmission housing 110 includes a first sub-shell 111 and a second sub-shell 112, and there is a gap at the connection between the first sub-shell 111 and the second sub-shell 112, in order to prevent impurities such as dust and water from flowing into the transmission module 10 from the connection between the first sub-shell 111 and the second sub-shell 112, the overall sealing effect of the transmission module 10 is improved.

[0077] In some embodiments, a third sealing ring 103 may be further provided. The third sealing ring 103 is provided around the circumference of the transmission shaft 130 . The third sealing ring 103 is located at an end of the first sub-shell 111 and abuts between the first sub-shell 111 and the second sub-shell 112 .

[0078] In this way, by introducing the third sealing ring 103 at the connection between the first sub-shell 111 and the second sub-shell 112, impurities such as dust and water can be prevented from flowing into the transmission module 10 from the connection between the first sub-shell 111 and the second sub-shell 112, thereby improving the overall sealing effect of the transmission module 10.

[0079] In some embodiments, the second sub-shell 112 is provided with a positioning groove, and the third sealing ring 103 is embedded in the positioning groove.

[0080] In this way, by embedding the third sealing ring 103 in the positioning groove, the third sealing ring 103 can be prevented from shifting and loosening as the transmission shaft 130 rotates, thereby improving the stability of the connection of the third sealing ring 103.

[0081] In some embodiments, the transmission module 10 further includes a shock absorbing sleeve 340 , which is sleeved on the outer periphery of the transmission body 100 . When the transmission body 100 is connected to the mesh cover shell 32 , the shock absorbing sleeve 340 abuts between the transmission body 100 and the mesh cover shell 32 .

[0082] By adding a shock-absorbing sleeve 340 wrapped around the outer surface of the transmission body 100 in the transmission module 10, and the shock-absorbing sleeve 340 abuts between the transmission body 100 and the mesh cover shell 32, and directly contacts the transmission body 100 and the mesh cover shell 32, when the fan blades 31 vibrate due to imbalance and transmit them to the transmission body 100, the shock-absorbing sleeve 340 on the outer surface of the transmission body 100 can effectively absorb and buffer these vibrations, reduce the vibration amplitude, and prevent the vibration from being transmitted to the mesh cover shell 32 and other moving parts of the fan 1, thereby reducing the shaking and swaying of the fan head 30 and other moving parts of the fan 1 due to the influence of vibration, thereby reducing the noise generated by the fan 1 during operation.

[0083] In some embodiments, the mesh housing 32 is provided with a plug-in slot 33, and the head housing 220 is provided with a plug-in end 222. When the mesh housing 32 is connected to the head housing 220, the plug-in end 222 can be plugged and matched with the plug-in slot 33;

[0084] The fan 1 includes a plurality of first shock absorbers 410 , which are arranged in sequence and spaced apart along the circumference of the plug-in end 222 . When the plug-in end 222 is plugged into the plug-in slot 33 , each first shock absorber 410 abuts between the fan head 30 and the plug-in end 222 along the radial direction of the plug-in end 222 .

[0085] In this way, each first shock absorbing member 410 abuts between the fan head 30 and the plug-in end 222 , which can reduce the vibration between the fan head 30 and the plug-in end 222 , and further reduce the vibration between the fan head 30 and the machine head 20 .

[0086] In addition, by providing a plug-in slot 33 on the fan head 30, the two ends of the first shock absorber 410 can be fixed to the fan head 30 and the machine head 20 respectively, thereby preventing the fan head 30 from shaking and swaying due to vibrations caused by the imbalance of the fan blades 31.

[0087] In some embodiments, the plug-in end 222 is provided with a plurality of first mounting grooves 223 , and the plurality of first mounting grooves 223 correspond to the plurality of first shock absorbing members 410 one by one, respectively, and each first shock absorbing member 410 is embedded in the corresponding first mounting groove 223 .

[0088] In this way, by providing the first installation groove 223 at the plug-in end 222 , the first shock absorbing member 410 can be embedded in the corresponding first installation groove 223 , thereby improving the installation stability of the first shock absorbing member 410 .

[0089] In some embodiments, a first clamping hole 2231 is provided on the wall surface of each first mounting groove 223 , and each first shock absorber 410 is provided with a first clamping column 4111 . Each first clamping column 4111 is clamped to the corresponding first clamping hole 2231 .

[0090] Thus, a first clamping hole 2231 is provided on the wall surface of the first installation groove 223 and a first clamping column 4111 is provided on the first shock absorber 410 , so that the first shock absorber 410 is clamped in the first clamping hole 2231 through the first clamping column 4111 and fixed on the plug-in end 222 of the machine head 20 .

[0091] In some embodiments, each first shock absorbing member 410 includes a first shock absorbing section 411 and a second shock absorbing section 412 connected to each other. When the plug-in end 222 is plugged into the plug-in slot 33, the first shock absorbing section 411 of each first shock absorbing member 410 abuts between the fan head 30 and the plug-in end 222 along the radial direction of the plug-in end 222, and the second shock absorbing section 412 of each first shock absorbing member 410 abuts between the fan head 30 and the plug-in end 222 along the axial direction of the plug-in end 222.

[0092] There are multiple first clamping columns 4111 of each first shock absorber 410, and the first shock absorber section 411 and the second shock absorber section 412 of each first shock absorber 410 are both provided with a first clamping column 4111; the wall surface of each first mounting groove 223 is provided with multiple first clamping holes 2231; the first clamping column 4111 is clamped in the corresponding first clamping hole 2231.

[0093] The first shock absorbing section 411 and the second shock absorbing section 412 may be perpendicular to each other.

[0094] In some embodiments, the first shock absorbing section 411 and the second shock absorbing section 412 may be configured to be in a square, circular, polygonal or other shape.

[0095] Since the square shape can provide a larger contact area, the first shock absorbing section 411 and the second shock absorbing section 412 of the first shock absorbing member 410 provided in the embodiment of the present application are both set to a square shape, so that the contact area between the first shock absorbing member 410 and the rear mesh 34 of the fan head 30 is larger. When vibration is transmitted from the fan head 30 along the machine head 20, the square-shaped shock absorbing section between the fan head 30 and the machine head 20 can absorb the vibration more effectively, thereby reducing the vibration transmission between the fan head 30 and the machine head 20.

[0096] In addition, the first shock absorber 410 is configured to be a first shock absorber section 411 and a second shock absorber section 412 that are connected, so that the first shock absorber section 411 and the second shock absorber section 412 can be clamped to the corresponding first clamping hole 2231 through the first clamping column 4111 of each of the first shock absorber section 411 and the second shock absorber section 412, thereby further improving the stability of the assembly of the first shock absorber 410 and preventing the first shock absorber 410 from loosening and falling off from the machine head 20.

[0097] In some embodiments, the first shock absorbing member 410 protrudes from the first installation slot 223 along the radial direction of the plug-in end 222 ; the first shock absorbing member 410 protrudes from the first installation slot 223 along the axial direction of the plug-in end 222 .

[0098] In this way, the first shock absorber 410 protrudes from the first mounting groove 223 along the radial direction of the plug-in end 222; the first shock absorber 410 protrudes from the first mounting groove 223 along the axial direction of the plug-in end 222, which can prevent the rear mesh 34 of the fan head 30 from directly contacting the plug-in end 222 of the machine head 20. When vibration is transmitted from the fan head 30 along the machine head 20, the protruding part of the first shock absorber 410 can absorb the vibration, thereby reducing the vibration transmission between the rear mesh 34 of the fan head 30 and the machine head 20.

[0099] In some embodiments, the fan 1 further includes a plurality of second dampers 420, which are arranged in sequence and at intervals along the circumferential direction of the axis of the plug end 222; when the plug end 222 is plugged into the plug slot 33, the second dampers 420 abut between the mesh housing 32 and the plug end 222 along the axial direction of the plug end 222. In this way, the plurality of second dampers 420 are arranged in sequence and at intervals along the circumferential direction of the axis of the plug end 222, and when the plug end 222 is plugged into the plug slot 33, that is, the fan head 30 is connected to the machine head 20, the vibration transmission between the fan head 30 and the machine head 20 can be reduced by the plurality of second dampers 420.

[0100] Among them, the second shock absorber 420 can have axial and radial shock absorption functions. The second shock absorber 420 provided in the embodiment of the present application mainly provides axial and radial shock absorption effects.

[0101] In some embodiments, the fan head 30 also includes a rear mesh 34, the plug-in slot 33 is arranged on the rear mesh 34, the rear mesh 34 is provided with a plurality of second mounting slots 341, the plug-in end 222 is provided with a plurality of third mounting slots 232, the plurality of second mounting slots 341 respectively correspond one-to-one with the plurality of third mounting slots 232, and the plurality of second shock absorbers 420 respectively correspond one-to-one with the plurality of third mounting slots 232, and when the plug-in end 222 is plugged into the plug-in slot 33, one end of each second shock absorber 420 is embedded in the corresponding second mounting slot 341, and the other end of each second shock absorber 420 is embedded in the corresponding third mounting slot 232.

[0102] In some embodiments, the second damper 420 can be configured in a cylindrical, square, or polygonal shape. Since the cylindrical second damper 420 is easier to align during installation, the second damper 420 in the embodiment provided by the present application is configured in a cylindrical shape, which can improve the efficiency and accuracy of the production and assembly of the fan 1.

[0103] In addition, the other end of the second shock absorber 420 is embedded in the second mounting groove 341 of the rear net 34, and the cylindrical surface is smooth without sharp edges and corners. Therefore, setting the second shock absorber 420 into a cylindrical shape can reduce the friction between the second shock absorber 420 and the contact surface.

[0104] In some embodiments, the second mounting groove 341 is provided with a through hole 3411 and a plurality of convex ribs 3412 , and the plurality of convex ribs 3412 are arranged at intervals along the circumference of the second mounting groove 341 .

[0105] When the soft glue and the hard glue are combined to form a sealed space, vacuum adsorption will be formed. That is, when the second shock absorber 420 is inserted into the second mounting groove 341 of the rear net 34, the second mounting groove 341 is easy to form a sealed space and then form vacuum adsorption. Vacuum adsorption will cause adsorption force between the fan head 30 and the machine head 20. Therefore, by providing a through hole 3411 and a plurality of ribs 3412 in the second mounting groove 341, it is possible to avoid the formation of a sealed space in the second mounting groove 341, thereby reducing the probability of vacuum adsorption in the second mounting groove 341, thereby reducing the axial vibration transmission between the fan head 30 and the machine head 20.

[0106] In some embodiments, the length of each second shock absorbing member 420 is greater than the sum of the length of the corresponding second mounting groove 341 and the length of the corresponding third mounting groove 232 .

[0107] In this way, the length of the second shock absorber 420 is greater than the sum of the length of the corresponding second mounting groove 341 and the length of the corresponding third mounting groove 232, which can prevent the rear mesh 34 of the fan head 30 from directly contacting the plug-in end 222 of the machine head 20. When the vibration is transmitted from the fan head 30 along the machine head 20, the vibration is first transmitted to the excess portion of the second shock absorber 420 between the fan head 30 and the machine head 20. Therefore, the excess portion of the second shock absorber 420 can be used to absorb the vibration first, thereby reducing the vibration transmitted to the machine head 20.

[0108] In some embodiments, the fan 1 further includes a clutch 230 , which is made of a soft material. The clutch 230 is connected to the output shaft 211 . When the mesh housing 32 is connected to the head housing 220 , the clutch 230 is coupled to the transmission shaft 130 .

[0109] The clutch 230 made of soft material is installed in the head housing 220 and coupled with the second end 132 of the transmission shaft 130, so that the clutch 230 serves as a transmission connection between the transmission shaft 130 and the output shaft 221, so that the output shaft 221 of the motor 210 transmits power to the transmission shaft 130 through the clutch 230, thereby driving the fan blades 120 to rotate. Since the clutch 230 made of soft material has good buffering performance, it can absorb part of the impact energy when the motor 210 starts and stops, reduce rigid collision, and thus reduce the noise generated by the entire fan 1, thereby improving the problem that the existing transmission system adopts a hard connection method, resulting in collisions between rigid connectors and generating abnormal impact noise.

[0110] Furthermore, since the clutch 230 is made of soft material, the friction and wear between the clutch 230 and the transmission shaft 130 and the output shaft 221 can be reduced, thereby extending the service life of components such as the transmission shaft 130 and the output shaft 221.

[0111] In addition, after the entire fan head 10 is removed, since the motor 210 may still be rotating, a clutch 230 made of soft material is installed on the outer periphery of the output shaft 221 of the motor 210. Even if the user accidentally touches the clutch 230, the soft material can effectively avoid causing harm to the user.

[0112] In some embodiments, the clutch 230 is a silicone clutch 230 or a rubber clutch 230 .

[0113] In some embodiments, the clutch 230 includes a connecting end 231 and a coupling end 232 that are connected to each other. The connecting end 231 is provided with a mounting hole 2311, and the mounting hole 2311 extends along the axial direction of the clutch 230. The clutch 230 is also provided with a metal connecting piece 240, and the metal connecting piece 240 is embedded in the mounting hole 2311, and the output shaft 211 is connected to the metal connecting piece 240; when the mesh cover shell 32 is connected to the head shell 220, the coupling end 232 is coupled with the transmission shaft 130.

[0114] Since the clutch is made of soft material, the connection strength provided by the soft material alone is relatively weak. Therefore, the introduction of the metal connector 240 can enhance the connection strength, thereby effectively supporting the connection of the clutch 230 and ensuring the stable connection between the clutch 230 and the output shaft 221 of the motor 210.

[0115] In addition, since soft materials are easily deformed, the metal connector 240 can provide precise positioning points to prevent the clutch 230 from deforming during installation, thereby making it easier to align the clutch 230 with the output shaft 221 of the motor 210 during installation, reducing the alignment and adjustment time, thereby improving the convenience of installing the clutch 230.

[0116] In some embodiments, the inner surface of the connecting end 231 is provided with a first anti-slip structure 2312 , and the outer surface of the metal connecting piece 240 is provided with a second anti-slip structure 2411 , and the second anti-slip structure 2411 and the first anti-slip structure 2312 are fixedly matched.

[0117] Since the metal connector 240 is embedded inside the connecting end 231 of the clutch 230, a first anti-slip structure 2312 is provided on the inner surface of the connecting end 231 and a second anti-slip structure 2411 is provided on the outer surface of the metal connector 240. Thus, the fixed cooperation between the first anti-slip structure 2312 and the second anti-slip structure 2411 can effectively prevent the metal connector 240 from sliding inside the clutch 230, thereby ensuring a stable connection between the clutch 230 and the output shaft 221 of the motor 210.

[0118] In some embodiments, the first anti-slip structure 2312 includes a plurality of first anti-slip ridges 2301, the plurality of first anti-slip ridges 2301 are sequentially arranged along the circumference of the output shaft 221, and each first anti-slip ridge 2301 extends along the axial direction of the output shaft 221;

[0119] The second anti-slip structure 2411 includes a plurality of second anti-slip convex strips 2401, which are sequentially arranged along the circumference of the output shaft 221, and each second anti-slip convex strip 2401 extends along the axial direction of the output shaft 221;

[0120] Each second anti-slip convex strip 2401 abuts against two adjacent first anti-slip convex strips 2301 .

[0121] The friction force of the inner surface of the connecting end 231 can be increased by providing a plurality of first anti-skid ridges 2301 . Similarly, the friction force of the outer surface of the metal connecting piece 240 can be increased by providing a second anti-skid structure 2411 including a plurality of second anti-skid ridges 2401 .

[0122] In addition, each second anti-slip ridge 2401 is abutted between two adjacent first anti-slip ridges 2301 to form a tight fixed fit, ensuring a tight fit between the metal connector 240 and the inner surface of the clutch 230, preventing the metal connector 240 from sliding inside the clutch 230, and thereby ensuring the stability and reliability of power transmission.

[0123] In some embodiments, the first anti-skid structure 2312 and the second anti-skid structure 2411 may also be friction surfaces. For example, the outer surface of the metal connector 240 and the inner surface of the connecting end 231 may be specially treated by sandblasting, scoring, chemical corrosion, etc. to form a rough friction surface, increase the roughness of the outer surface of the metal connector 240 and the inner surface of the connecting end 231, and thus effectively prevent the metal connector 240 from sliding in the clutch 230, ensuring a stable connection between the clutch 230 and the output shaft 221 of the motor 210.

[0124] In some embodiments, the metal connector 240 is threadedly connected to the output shaft 221 .

[0125] The inner surface of the metal connector 240 may be provided with an internal thread, and the end of the output shaft 221 of the motor 210 may be provided with an external thread. Alternatively, the inner surface of the metal connector 240 may be provided with an external thread, and the end of the output shaft 221 of the motor 210 may be provided with an internal thread.

[0126] In this way, the metal connector 240 is threadedly connected to the output shaft 221, so that when vibration is generated during the operation of the motor 210, the stability of the connection between the metal connector 240 and the output shaft 221 of the motor 210 can be maintained to avoid loosening or falling off due to vibration.

[0127] In addition, the threaded connection is easy to operate and can be installed and disassembled by simply tightening or loosening, making it convenient for users to perform maintenance and replacement.

[0128] In some embodiments, the second end 132 is provided with a connecting pin 1321, and the connecting pin 1321 is radially penetrated through the second end 132 along the transmission shaft 130, and the coupling end 232 includes a plurality of coupling teeth 2321, and the plurality of coupling teeth 2321 are all connected to the connecting end 231, and the plurality of coupling teeth 2321 are arranged in sequence along the circumference of the output shaft 221, and two adjacent coupling teeth 2321 are spaced apart to form a coupling groove 233, and the coupling groove 233 has an opening 234, and the opening 234 is used for the connecting pin 1321 to be placed in the coupling groove 233; when the mesh cover shell 110 is connected to the head shell 220, the connecting pin 1321 is embedded in at least one coupling groove 233.

[0129] In this way, by setting a plurality of coupling teeth 2321 at the coupling end 232 of the clutch 230, a coupling groove 233 with an opening 234 is formed between two adjacent coupling teeth 2321. The connecting pin 1321 can be embedded in the coupling groove 233 by simply aligning the connecting pin 1321 with the coupling groove 233 through the opening 234, thereby improving the convenience of the installation and disassembly process of the connecting pin 1321.

[0130] In some embodiments, guide slopes 235 are provided on opposite sides of the coupling teeth 2321 along the circumference of the clutch 230 , and the guide slopes 235 are used to guide the connecting pin 1321 into at least one coupling groove 233 .

[0131] The guiding slope 235 may be designed in a V shape.

[0132] Since the traditional clutch 230 is prone to getting stuck during assembly, the present application provides guide bevels 235 on opposite sides of the clutch 230 in the circumferential direction. The guide bevels 235 can guide the connecting pin 1321 to smoothly enter the coupling groove 233 to prevent it from getting stuck during the assembly process. The design of the guide bevels 235 allows the connecting pin 1321 to automatically align and be placed in the coupling groove 233 when it touches the bevel of the clutch 230, thereby reducing the error of manual alignment and improving the convenience of assembling the connecting pin 1321.

[0133] In some embodiments, the plurality of coupling slots 233 include a first coupling slot 2331, a second coupling slot 2332, a third clutch slot 2333 and a fourth clutch slot 2334. The first coupling slot 2331, the second coupling slot 2332, the third clutch slot 2333 and the fourth clutch slot 2334 are arranged in sequence along the circumference of the clutch 230. The first clutch slot and the third coupling slot 233 are symmetrically arranged along the axis of the clutch 230; the second clutch slot and the fourth coupling slot 233 are symmetrically arranged along the axis of the clutch 230; when the mesh cover shell 110 is connected to the head shell 220, the connecting pin 1321 is embedded in the first clutch slot and the third coupling slot 233; or, the connecting pin 1321 is embedded in the second clutch slot and the fourth coupling slot 233.

[0134] In this way, embedding the connecting pin 1321 in two symmetrically arranged coupling grooves 233 (such as the first clutch groove and the third coupling groove 233; or the second clutch groove and the fourth coupling groove 233) can effectively prevent relative rotation between the transmission shaft 130 and the clutch 230.

[0135] In some embodiments, the head housing 220 is provided with a mounting groove, and the clutch 230 is located in the mounting groove.

[0136] The shape and size of the mounting groove match the clutch 230 to ensure that the clutch 230 can be smoothly placed and fixed in the mounting groove.

[0137] Thus, by providing a mounting groove on the head housing 220 and placing the clutch 230 in the mounting groove, external impurities such as dust and moisture can be effectively prevented from entering the metal connector 240 inside the clutch 230, thereby extending the service life of the metal connector 240. In addition, the mounting groove allows the clutch 230 to be better integrated into the head housing 220, saving space and making the entire fan 1 more compact.
