DETAILED DESCRIPTION

[0041] To make the objectives, technical solutions, and superiorities of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0042] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplifying the present application, the components and settings of specific examples are described in the following. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and it does not indicate the relationship between the various embodiments and / or settings discussed.

[0043] For the convenience of description, spatial relative terms can be used in the specification to describe the relative position relationship or movement condition of one element or feature relative to another element or feature as shown in the drawings, such as "inner", "outer", "inboard", "outboard", "under", "below", "on", "above", "front", "back", and the like. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over or reversed, or the orientation or movement state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be subsequently oriented as "above" or "above" another element or feature. Therefore, the example term "below" can include both upward and downward positions. The device can be additionally oriented (rotated by 90 degrees or in other directions), and the spatial relative relationship descriptors used in the specification are interpreted accordingly.

[0044] Fans are widely used in daily life and industrial production. Its working principle is to drive the fan blade to rotate by the motor, so that the surrounding air is accelerated to flow, thereby generating wind power, achieving the purpose of cooling and relieving summer heat or air circulation.

[0045] The fan generally includes a fan head and a driving assembly connected together, and the fan head mainly includes a front net, a rear net and a fan blade. The existing fan products need to be disassembled one by one from the driving assembly when cleaning the front net, the rear net and the fan blade, which leads to complex disassembly.

[0046] Therefore, in order to solve the technical problem that the existing fan products need to be disassembled one by one from the front net, the rear net and the fan blade when cleaning, which leads to complex disassembly, the application provides a fan which can improve the convenience of fan disassembly, and further improve the convenience and efficiency of fan cleaning. For details, please refer to the following embodiments.

[0047] Referring to Figures 1-15 The fan 1 provided by the application includes a transmission module 10, a machine head 20, and a fan head 30.

[0048] The machine head 20 includes a motor 210 and a machine head shell 220, the motor 210 is installed on the machine head shell 220, and the motor 210 has an output shaft 211.

[0049] The fan head 30 includes a mesh cover shell 32 and a fan blade 31, the fan blade 31 is installed in the mesh cover shell 32; the mesh cover shell 32 is detachably connected to the machine head shell 220, and the mesh cover shell 32 is provided with a movable lock catch mechanism 300, which can selectively be in a locked state or an unlocked state.

[0050] The transmission module 10 is mounted on the mesh shell and connected to the fan blades 31. When the mesh shell 32 is connected to the head shell 220 and the locking mechanism 300 is in the locked state, the mesh shell 32 can be fixedly connected with 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 the unlocked state, the mesh 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 provided as a detachable connection of the head 20, the fan head 30 and the transmission module 10, wherein the fan head 30 includes the mesh shell 32 and the fan blades 31, the fan blades 31 are mounted in the mesh shell 32, the mesh shell 32 is detachably connected to the head shell 220 of the head 20, and the transmission module 10 is mounted on the mesh shell and connected to the fan blades 31. Since the mesh shell 32 is provided with the movable locking mechanism 300, and the locking mechanism 300 can be selectively in the locked state or the unlocked state, when the locking mechanism 300 is in the unlocked state, the mesh 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 locking mechanism 300 only needs to be moved to the unlocked state to separate the fan head 30 from the driving assembly, that is, only one step operation is needed to quickly disassemble the fan head 30 from the driving assembly as a whole, without the need for the complex process of disassembling each component (such as the front mesh, the fan blades, and the rear mesh) included in the fan head 30 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 shell 32 is connected to the head shell 220 and the locking mechanism 300 is in the locked state, the mesh shell 32 can be fixedly connected with the head shell 220, and the output shaft 211 is coupled to the transmission module 10 to drive the fan blades 31 to rotate. By moving the locking mechanism 300, the locking mechanism 300 can be in the locked state to make the connection between the fan head 30 and the head 20 more stable, thereby improving the safety of the fan 1 in use and helping to reduce the safety risk caused by loose or falling parts.

[0053] In some embodiments, the mesh shell 32 can be detachably connected to the head shell 220 by buckling, screwing, plugging, etc.

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

[0055] In some embodiments, the locking mechanism 300 comprises a locking piece 310 movably mounted on the net cover housing 32, and the head housing 220 is provided with a locking slot 221, when the net cover housing 32 is connected to the head housing 220 and the locking mechanism 300 is in the locked state, the locking piece 310 is partially located in the locking slot 221; when the locking mechanism 300 is in the unlocked state, the locking piece 310 is located outside the locking slot 221, and the net cover housing 32 can be separated from the head housing 220.

[0056] Since the locking piece 310 is movably mounted on the net cover housing 32, when the net cover housing 32 is connected to the head housing 220, the locking piece 310 can be moved towards the locking slot 221, so that part of the locking piece 310 is located in the locking slot 221 and is inserted with the locking slot 221, thereby ensuring the stable connection between the net cover housing 32 and the head housing 220; when it is needed to disassemble the net cover housing 32 from the head housing 220, the locking piece 310 is moved in the opposite direction of the locking slot 221, so that the locking piece 310 is completely moved out of the locking slot 221, thereby driving the net cover housing 32 to move in the opposite direction of the locking slot 221, so as to be separated from the head housing 220, thereby realizing the separation of the fan head 30 and the head 20, and improving the convenience of disassembling the fan head 30.

[0057] In some embodiments, the locking mechanism 300 further comprises a resilient piece 320 and a connecting piece 330; the connecting piece 330 is fixed on the net cover housing 32, the locking piece 310 is mounted between the connecting piece 330 and the net cover housing 32, and the resilient piece 320 is mounted between the connecting piece 330 and the locking piece 310.

[0058] In some embodiments, the resilient piece 320 can also be mounted between the net cover housing 32 and the locking piece 310.

[0059] The length direction of the resilient piece 320 extends along the radial direction of the head 20.

[0060] In some embodiments, the connecting piece 330 can be fixedly connected to the fan head 30 by screws or the like.

[0061] In some embodiments, the resilient piece 320 can be a spring or other material or element with elastic properties.

[0062] For example, when the locking piece 310 is moved in the opposite direction of the locking slot 221, the resilient piece 320 is compressed, so that the locking piece 310 can be moved out of the locking slot 221, thereby enabling the fan head 30 to be separated from the driving assembly 100; when the locking piece 310 is released, the locking piece 310 is reset under the action of the resilient piece 320, and the locking mechanism 300 is in the locked state, that is, part of the locking piece 310 is located in the locking slot 221 and is inserted with the locking slot 221.

[0063] Thus, by arranging the elastic member 320, the user only needs to move the locking member 310 to the unlocked state, and after releasing the hand, the elastic member 320 can automatically restore the locking member 310 to the locked state, so 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 more convenient and fast.

[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 that the fan 10 will be accidentally unlocked due to vibration or collision during use, thereby improving the safety of the fan 10 in use.

[0065] In some embodiments, the transmission module 10 includes a transmission body 100 and a transmission shaft 130, the transmission shaft 130 is rotatably arranged in the transmission body 100, and the transmission body 100 is detachably connected to the mesh cover housing 32; when the transmission body 100 is connected to the mesh cover housing 32, one end of the transmission shaft 130 is arranged in the fan blade 31; when the mesh cover housing 32 is connected to the head housing 220, the output shaft 211 is coupled 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 cover housing 32, when the mesh cover housing 32 is connected to the head housing 220, the output shaft 211 is coupled 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, so that the fan blade 31 in the fan head 30 can be separated from the transmission module 10 and the output shaft 211 of the motor 210, which improves the existing fan 1 in which the fan blade is connected to the motor shaft and the motor shaft pin through the shaft connecting head integrated with the fan blade 31, so that the fan head 30 can be detached as a whole from the drive assembly, avoiding the complex process of detaching each component of 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 containing 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 communicated with the containing space and located on opposite sides of the transmission housing 110, and the transmission shaft 130 is rotatably connected to the transmission housing 110 through the bearing 120 and arranged in the first connecting hole 140 and the second connecting hole 150;

[0068] The first sealing ring 101 is sleeved on the outer periphery 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 periphery 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 sleeved on the outer periphery of the transmission shaft 130 and abutting between the transmission housing 110 and the transmission shaft 130, and the second sealing ring 102 sleeved on the outer periphery of the transmission shaft 130 and abutting between the transmission housing 110 and the transmission shaft 130, the first connecting hole 140 and the second connecting hole 150 are blocked by the first sealing ring 101 and the second sealing ring 102 respectively, forming double sealing, effectively preventing impurities such as dust and water from entering the inside of the transmission module 10, reducing the damage of impurities such as dust and water to the bearing 120 inside the transmission module 10, and prolonging the service life of the transmission module 10.

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

[0071] The first sub-housing 111 can be detachably connected to the second sub-housing 112 by threaded connection, buckle connection, magnetic attraction connection, or bolt connection.

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

[0073] For example, in some embodiments, the first sub-housing 111 is provided with a first buckle structure, and the second sub-housing 112 is provided with a second buckle structure, and the second buckle structure can be buckled and fixed with the first buckle structure.

[0074] The first buckle structure can be a clamping protrusion, and the second buckle structure can be a clamping groove, and the buckle can be embedded in the clamping groove.

[0075] In this way, the buckle connection can be completed by simple pressing or rotating action without the need for complex tools or operation steps. In addition, the buckle connection is more firm and less likely to loosen, ensuring the stability and reliability of the transmission module 10.

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

[0077] In some embodiments, a third sealing ring 103 can also be provided, which is arranged around the circumference of the transmission shaft 130, and is located at the end of the first sub-housing 111 and abuts between the first sub-housing 111 and the second sub-housing 112.

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

[0079] In some embodiments, the second sub-housing 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, displacement and loosening of the third sealing ring 103 due to rotation of the transmission shaft 130 can be avoided, thereby improving the stability of the connection of the third sealing ring 103.

[0081] In some embodiments, the transmission module 10 further comprises a shock-absorbing sleeve 340, which is sleeved around the outer periphery of the transmission main body 100, and abuts between the transmission main body 100 and the mesh housing 32 when the transmission main body 100 is connected to the mesh housing 32.

[0082] By adding the shock-absorbing sleeve 340 wrapped around the outer surface of the transmission main body 100 in the transmission module 10, and the shock-absorbing sleeve 340 abutting between the transmission main body 100 and the mesh housing 32, directly contacting the transmission main body 100 and the mesh housing 32, in this way, when the fan blades 31 vibrate due to imbalance and transmit to the transmission main body 100, the shock-absorbing sleeve 340 on the outer surface of the transmission main body 100 can effectively absorb and buffer these vibrations, reduce the vibration amplitude, prevent the vibrations from being transmitted to the mesh housing 32 and other moving parts of the fan 1, thereby reducing the phenomenon that the fan head 30 and other moving parts of the fan 1 are affected by the vibrations and cause shaking, 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 groove 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 into the plug-in groove 33.

[0084] The fan 1 comprises a plurality of first damping members 410, which are arranged in sequence along the circumference of the insertion end 222, and each first damping member 410 abuts between the fan head 30 and the insertion end 222 in the radial direction of the insertion end 222 when the insertion end 222 is inserted into the insertion slot 33.

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

[0086] In addition, by arranging the insertion slot 33 on the fan head 30, the two ends of the first damping member 410 can be fixed on the fan head 30 and the machine head 20 respectively, which can prevent the fan head 30 from easily shaking due to the vibration caused by the unbalanced fan blades 31.

[0087] In some embodiments, the insertion end 222 is provided with a plurality of first mounting slots 223, which correspond to the plurality of first damping members 410 one by one, and each first damping member 410 is embedded in the corresponding first mounting slot 223.

[0088] In this way, by arranging the first mounting slot 223 on the insertion end 222, the first damping member 410 can be embedded in the corresponding first mounting slot 223, which can improve the stability of the installation of the first damping member 410.

[0089] In some embodiments, the wall surface of each first mounting slot 223 is provided with a first clamping hole 2231, and each first damping member 410 is provided with a first clamping column 4111, and each first clamping column 4111 is clamped in the corresponding first clamping hole 2231.

[0090] In this way, the first clamping hole 2231 is arranged on the wall surface of the first mounting slot 223, and the first clamping column 4111 is arranged on the first damping member 410, so that the first damping member 410 is clamped on the insertion end 222 of the machine head 20 by the first clamping column 4111 clamped in the first clamping hole 2231.

[0091] In some embodiments, each first damping member 410 comprises a first damping section 411 and a second damping section 412 connected to each other, and when the insertion end 222 is inserted into the insertion slot 33, the first damping section 411 of each first damping member 410 abuts between the fan head 30 and the insertion end 222 in the radial direction of the insertion end 222, and the second damping section 412 of each first damping member 410 abuts between the fan head 30 and the insertion end 222 in the axial direction of the insertion end 222.

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

[0093] The first damping section 411 and the second damping section 412 can be perpendicular to each other.

[0094] In some embodiments, the first damping section 411 and the second damping section 412 can be square, circular, polygonal or the like.

[0095] Since the square shape can provide a larger contact area, the first damping section 411 and the second damping section 412 of the first damping part 410 are both provided as square in the embodiment of the application, so that the contact area between the first damping part 410 and the rear net 34 of the fan head 30 is larger, and when the vibration is transmitted from the fan head 30 to the handle 20, the square-shaped damping section between the fan head 30 and the handle 20 can more effectively absorb the vibration, thereby reducing the vibration transmission between the fan head 30 and the handle 20.

[0096] In addition, the first damping part 410 is provided as the first damping section 411 and the second damping section 412 connected to each other, so that the first clamping column 4111 of each of the first damping section 411 and the second damping section 412 is clamped in the corresponding first clamping hole 2231, thereby further improving the stability of the assembly of the first damping part 410 and preventing the first damping part 410 from loosening and falling off from the handle 20.

[0097] In some embodiments, the first damping part 410 protrudes from the first mounting groove 223 in the radial direction of the plug-in end 222; and the first damping part 410 protrudes from the first mounting groove 223 in the axial direction of the plug-in end 222.

[0098] In this way, the first damping part 410 protrudes from the first mounting groove 223 in the radial direction of the plug-in end 222; and the first damping part 410 protrudes from the first mounting groove 223 in the axial direction of the plug-in end 222, which can avoid the direct contact between the rear net 34 of the fan head 30 and the plug-in end 222 of the handle 20, and when the vibration is transmitted from the fan head 30 to the handle 20, the protruding part of the first damping part 410 can absorb the vibration, thereby reducing the vibration transmission between the rear net 34 of the fan head 30 and the handle 20.

[0099] In some embodiments, the fan 1 further comprises a plurality of second damping members 420, which are arranged in sequence along the circumference of the axis of the insertion end 222; when the insertion end 222 is inserted into the insertion slot 33, the second damping members 420 abut between the mesh cover housing 32 and the insertion end 222 along the axial direction of the insertion end 222. In this way, the plurality of second damping members 420 arranged in sequence along the circumference of the axis of the insertion end 222 can reduce the transmission of vibration between the fan head 30 and the machine head 20 when the insertion end 222 is inserted into the insertion slot 33, i.e., when the fan head 30 is connected to the machine head 20.

[0100] In some embodiments, the second damping member 420 can have axial and radial damping functions, and the second damping member 420 provided in the embodiments of the present application mainly provides radial damping effect.

[0101] In some embodiments, the fan head 30 further comprises a rear mesh 34, and the insertion slot 33 is arranged on the rear mesh 34. The rear mesh 34 is provided with a plurality of second mounting grooves 341, and the insertion end 222 is provided with a plurality of third mounting grooves 232. The plurality of second mounting grooves 341 correspond to the plurality of third mounting grooves 232 one by one, and the plurality of second damping members 420 correspond to the plurality of third mounting grooves 232 one by one. When the insertion end 222 is inserted into the insertion slot 33, one end of each second damping member 420 is embedded in the corresponding second mounting groove 341, and the other end of each second damping member 420 is embedded in the corresponding third mounting groove 232.

[0102] In some embodiments, the second damping member 420 can be provided in the shape of a cylinder, a square, or a polygon. Since the cylindrical second damping member 420 is easier to align during installation, the second damping member 420 provided in the embodiments of the present application is in the shape of a cylinder, 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 damping member 420 is embedded in the second mounting groove 341 of the rear mesh 34, and the surface of the cylinder is smooth without sharp edges and corners. Therefore, the second damping member 420 is provided in the shape of a cylinder, which can reduce the friction between the second damping member 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 protruding ribs 3412, which are arranged in sequence along the circumference of the second mounting groove 341.

[0105] When the soft rubber and the hard rubber are matched, a vacuum adsorption is formed if a sealed space is formed. When the second damping member 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 a vacuum adsorption. The vacuum adsorption causes the adsorption force between the fan head 30 and the machine head 20. Therefore, by providing the through hole 3411 and the plurality of protruding ribs 3412 in the second mounting groove 341, the second mounting groove 341 is prevented from forming a sealed space, and the probability of the vacuum adsorption of the second mounting groove 341 is reduced, 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 damping 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 damping 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. The rear net 34 of the fan head 30 is prevented from directly contacting the insertion end 222 of the machine head 20. When the vibration is transmitted from the fan head 30 to the machine head 20, the vibration is first transmitted to the excess part of the second damping member 420 between the fan head 30 and the machine head 20. Therefore, the excess part of the second damping member 420 can be used to first absorb the vibration, and then the vibration transmitted to the machine head 20 is reduced.

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

[0109] The clutch 230 made of soft material is installed in the machine head housing 220 and coupled with the second end 132 of the transmission shaft 130. The clutch 230 serves as a transmission connecting member between the transmission shaft 130 and the output shaft 221. The output shaft 221 of the motor 210 transmits power to the transmission shaft 130 through the clutch 230, thereby driving the fan blade 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 the rigid collision, and thus reduce the noise generated by the entire fan 1. In this way, the problem of collision between the hard connecting members in the existing transmission system is solved, and the impact noise is avoided.

[0110] In addition, 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 are reduced, thereby prolonging the service life of the transmission shaft 130 and the output shaft 221 and other components.

[0111] In addition, when the entire fan head 10 is removed, since the motor 210 can still be rotating, the clutch 230 made of soft material is installed on the outer periphery of the output shaft 221 of the motor 210, so that even if the user accidentally touches the clutch 230, the soft material can effectively avoid injury to the user.

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

[0113] In some embodiments, the clutch 230 includes a connecting end 231 and a coupling end 232 connected together, the connecting end 231 is provided with a mounting hole 2311 extending along the axial direction of the clutch 230, the clutch 230 is also provided with a metal connecting piece 240 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 motor 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 metal connecting piece 240 is introduced to 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 the soft material is prone to deformation, the metal connecting piece 240 can provide an accurate positioning point, which can prevent the clutch 230 from deforming during installation, thereby making it easier for the clutch 230 to align with the output shaft 221 of the motor 210 during installation, reducing the time for alignment and adjustment, and thus 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 connecting piece 240 is embedded inside the connecting end 231 of the clutch 230, by providing the first anti-slip structure 2312 on the inner surface of the connecting end 231 and the second anti-slip structure 2411 on the outer surface of the metal connecting piece 240, the fixed matching of the first anti-slip structure 2312 and the second anti-slip structure 2411 can effectively prevent the metal connecting piece 240 from sliding inside the clutch 230, thereby ensuring the stable connection between the clutch 230 and the output shaft 221 of the motor 210.

[0118] In some embodiments, the first anti-skid structure 2312 includes a plurality of first anti-skid protrusions 2301 arranged along the circumference of the output shaft 221, each of the first anti-skid protrusions 2301 extending along the axial direction of the output shaft 221.

[0119] The second anti-skid structure 2411 includes a plurality of second anti-skid protrusions 2401 arranged along the circumference of the output shaft 221, each of the second anti-skid protrusions 2401 extending along the axial direction of the output shaft 221.

[0120] Each of the second anti-skid protrusions 2401 abuts between two adjacent first anti-skid protrusions 2301.

[0121] By arranging the plurality of first anti-skid protrusions 2301, the friction of the inner surface of the connecting end 231 can be increased. Similarly, by arranging the second anti-skid structure 2411 including the plurality of second anti-skid protrusions 2401 on the outer surface of the metal connecting piece 240, the friction of the outer surface of the metal connecting piece 240 can also be increased.

[0122] In addition, by arranging each of the second anti-skid protrusions 2401 to abut between two adjacent first anti-skid protrusions 2301, a tight and fixed fit is formed, ensuring a tight fit between the metal connecting piece 240 and the inner surface of the clutch 230, preventing the metal connecting piece 240 from sliding within the clutch 230, and further 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 can also be friction surfaces. For example, the outer surface of the metal connecting piece 240 and the inner surface of the connecting end 231 can be specially treated by methods such as sandblasting, scoring, and chemical etching to form rough friction surfaces, increasing the roughness of the outer surface of the metal connecting piece 240 and the inner surface of the connecting end 231, and further effectively preventing the metal connecting piece 240 from sliding within the clutch 230, ensuring stable connection between the clutch 230 and the output shaft 221 of the motor 210.

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

[0125] In some embodiments, the inner surface of the metal connecting piece 240 can be provided with internal threads, and the end of the output shaft 221 of the motor 210 can be provided with external threads. Alternatively, the inner surface of the metal connecting piece 240 can be provided with external threads, and the end of the output shaft 221 of the motor 210 can be provided with internal threads.

[0126] In this way, the metal connecting piece 240 is screwed to the output shaft 221, so that the stability of the connection between the metal connecting piece 240 and the output shaft 221 of the motor 210 can be maintained during the vibration of the motor 210, and loosening or falling caused by vibration can be avoided.

[0127] In addition, the threaded connection operation is simple, and only needs to be screwed or unscrewed to complete the installation and disassembly, which is convenient for users to maintain and replace.

[0128] In some embodiments, the second end 132 is provided with a connecting pin 1321 penetrating the second end 132 along the radial direction of the transmission shaft 130, the coupling end 232 includes a plurality of coupling teeth 2321, the plurality of coupling teeth 2321 are connected to the connecting end 231, the plurality of coupling teeth 2321 are sequentially and spaced arranged along the circumferential direction of the output shaft 221, and a coupling groove 233 is formed between adjacent two coupling teeth 2321, the coupling groove 233 has an opening 234 for placing the connecting pin 1321 into 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 arranging a plurality of coupling teeth 2321 on the coupling end 232 of the clutch 230, and forming a coupling groove 233 with an opening 234 between adjacent two coupling teeth 2321, the connecting pin 1321 can be embedded in the coupling groove 233 by 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, the coupling teeth 2321 are provided with a guide slope 235 on the opposite sides along the circumferential direction of the clutch 230, and the guide slope 235 is used to guide the connecting pin 1321 into at least one coupling groove 233.

[0131] The guide slope 235 can be designed in a V shape.

[0132] Since the traditional clutch 230 is prone to jamming during assembly, the present application is provided with a guide slope 235 on the opposite sides along the circumferential direction of the clutch 230, which can guide the connecting pin 1321 to smoothly enter the coupling groove 233, prevent jamming during assembly, and the design of the guide slope 235 enables the connecting pin 1321 to be automatically aligned and placed into the coupling groove 233 when it touches the slope of the clutch 230, reduces the error caused by manual alignment, and improves the convenience of the assembly of the connecting pin 1321.

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

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

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

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

[0137] In this way, by providing a mounting groove on the head shell 220 and placing the clutch 230 in the mounting groove, the metal connecting piece 240 inside the clutch 230 can be effectively prevented from being contaminated by external impurities such as dust and moisture, thereby prolonging the service life of the metal connecting piece 240. Moreover, the mounting groove allows the clutch 230 to be better integrated into the interior of the head shell 220, saving space and making the entire fan 1 structure more compact.
