[0051] Reference Figures 1 to 12 The first aspect of this application provides a fan, including a fan body and a battery 30. The fan body includes a head 10 and fan blades 20, and the head 10 is capable of driving the fan blades 20 to rotate. The head 10 includes a fan blade drive assembly 100, which includes a first drive assembly 110, a mounting base 113, and a first mounting member 120. The first drive assembly 110 includes a first drive member 111, which is connected to the first mounting member 120. The first drive member 111 can be directly connected to the first mounting member 120, or as... Figure 2 As shown, the first driving member 111 can be indirectly connected to the first mounting member 120 via a fixed shaft 112. The mounting base 113 is connected to the first driving member 111, and the first driving member 111 can drive the mounting base 113 to rotate about the X-axis. (Refer to...) Figure 7 The fan blade 20 includes a fan blade seat 21 and multiple blades 22. The fan blade seat 21 is sleeved on the mounting base 113, and the multiple blades 22 are connected to the outer surface of the fan blade seat 21 and spaced apart in the circumferential direction. The battery 30 is detachably connected to the side of the first mounting member 120 opposite to the first drive assembly 110. Along the Y-axis direction, the battery 30 is located within the projection range of the mounting base 113.

[0052] The first driving component 111 can drive the mounting base 113 to rotate, thereby causing the fan blades 20 to rotate. The airflow generated by the rotation of the fan blades 20 is also distributed around the mounting base 113. The battery 30 is connected to the first mounting member 120 and is located within the projection range of the mounting base 113 along the Y-axis direction, so that the battery 30 is not in the airflow path when connected to the first mounting member 120, thereby reducing its impact on the airflow. The battery 30 can be either detachably connected to the first mounting member 120 or fixedly connected to the first mounting member 120.

[0053] Reference Figures 2 to 4In some embodiments, the machine head 10 further includes a rotating assembly 200, which includes a fixed base 210, a rotating member 220, and a second drive assembly 240. The second drive assembly 240 includes a second drive member 241 and a movable member 242. The fixed base 210 is provided with a receiving cavity 211, the rotating member 220 is received in the receiving cavity 211, and the second drive assembly 240 is received in the receiving cavity 211 and connected to the rotating member 220. For example, see Reference Figure 3 and Figure 5 The rotating member 220 may be provided with a mounting cavity 2211. The second drive assembly 240 is housed in the mounting cavity 2211 and connected to the rotating member 220. Thus, both the rotating member 220 and the second drive assembly 240 are housed within the housing cavity 211. The second drive assembly 241 can drive the movable member 242 to move, thereby causing the rotating member 220 to rotate relative to the fixed base 210 around the Z-axis. The rotating assembly 200 also includes a second mounting member 230, which is rotatably connected to the first mounting member 120. The rotating member 220 is connected to the second mounting member 230. The first drive assembly 111 and the second drive assembly 241 are respectively connected to and fixed to the first mounting member 120 and the second mounting member 230. The first mounting member 120 and the second mounting member 230 are rotatably connected. When the fan head 10 is used as a fan, it can meet the requirements of air outlet, air outlet direction change around the X-axis, and fan rotation around the Z-axis for air outlet, while using fewer parts. This simplifies the installation process of the fan head 10 and reduces costs. Meanwhile, the aforementioned fan head 10 features a modular design, making it compatible with different types of fans. Both the first drive component 111 and the second drive component 241 can be selected as motors.

[0054] Specifically, both the first mounting component 120 and the second mounting component 230 are sheet metal parts. While having a certain strength and not easily deforming, they are also relatively lightweight. Therefore, the force required for the second driving component 241 to drive the rotating component 220 to rotate through the driving gear is relatively small. Thus, the second driving component 241 can be selected as a motor with a smaller power, which can drive the rotating component 220 to rotate relative to the fixed base 210. It is also relatively small in size, making it easy to store and collect.

[0055] Reference Figure 3 and Figure 4In some embodiments, the fan head 10 further includes a panel 101, and the first drive assembly 110 further includes a fixed shaft 112. The fixed shaft 112 is disposed within the mounting base 113 and passes through the first drive member 111. The panel 101 and the first mounting member 120 are respectively located at both ends of the mounting base 113 along its length. The panel 101 is fixedly connected to the fixed shaft 112. The fixed shaft 112 is hollow inside and forms a first channel 1121. The first channel 1121 is used to pass wires through, and the wires can extend to the panel 101 and the first mounting member 120. The first mounting member 120 can be electrically connected to a power source. The power source can be an external power source or a built-in power source such as a battery located on the fan head. When the fan is in use, the first drive member 111 can drive the mounting base 113 and the fan blades 20 to rotate together, thereby achieving airflow. Furthermore, when different airflow effects are required, fan blades 20 with different blade shapes can be replaced. Panel 101 can be a touch panel and is electrically connected to the power supply via wires passing through the first channel 1121. When the first driving member 111 drives the mounting base 113 to rotate, the electrical connection between panel 101 and the external power supply will not be affected, ensuring the stability of the power supply to panel 101. Specifically, the first driving component 110 can be an external rotor motor including an iron core coil and a magnetic ring. That is, the first driving member 111 is an iron core coil sleeved on the fixed shaft 112, and the magnetic ring is disposed in the mounting base 113. The iron core coil can generate a changing magnetic field to drive the mounting base 113 to rotate.

[0056] Reference Figure 4 In some embodiments, the fan head 10 further includes a damper 102, which is disposed at the connection between the first mounting member 120 and the second mounting member 230. The damper 102 can fix the first mounting member 120 and the second mounting member 230 so that the first mounting member 120 and the second mounting member 230 have a set angle around the Y-axis. When it is necessary to adjust the angle between the first mounting member 120 and the second mounting member 230 around the Y-axis, since the second mounting member 230 is generally connected to the support assembly 400, it is only necessary to apply a force around the Y-axis to the first mounting member 120 to rotate the first mounting member 120 relative to the second mounting member 230 into place. The damper 102 can ensure that the posture of the first mounting member 120 relative to the second mounting member 230 does not change without other external forces, so that the angle of the airflow relative to the XY plane does not change when the fan is blowing air.

[0057] Reference Figure 4In some embodiments, the first mounting member 120 includes a main body 121 and a connecting part 122. The first drive assembly 110 is connected to the main body 121. The second mounting member 230 is provided with a mounting hole, and the damper 102 passes through the mounting hole and is connected to the connecting part 122. Specifically, the extension directions of the main body 121 and the connecting part 122 are perpendicular to each other. The head 10 also includes a first support member 104. The first mounting member 120 is provided with two connecting parts 122 spaced apart along the Y-axis. The connecting parts 122 are provided with through holes. The damper 102 passes through the mounting hole and the through hole of one connecting part 122. The first support member 104 passes through the mounting hole and the through hole of the other connecting part 122 and extends towards the main body 121 to strengthen the connection strength between the connecting part 122 and the main body 121. The damper 102 and the first support member 104 are both connected to the connecting part 122 and the second mounting member 230 by fasteners.

[0058] Reference Figure 4 and Figure 6 In some embodiments, the rotating member 220 is provided with a mounting portion 221, which has a mounting cavity 2211 and a first opening 2212. The first opening 2212 connects the receiving cavity 211 and the mounting cavity 2211. The movable member 242 passes through the first opening 2212 and contacts the inner wall of the fixed seat 210. Specifically, the inner wall of the fixed seat 210 is arc-shaped and has a plurality of internal teeth 213 arranged sequentially along the circumferential direction. The movable member 242 is selected as a gear, which meshes with the internal teeth 213 arranged on the fixed seat 210. The second driving member 241 drives the movable member 242 to rotate, causing the rotating member 220 to rotate relative to the fixed seat 210, thereby changing the direction of the fan's airflow. It can be understood that the gear transmission achieves better stability in the rotation of the rotating member 220 relative to the fixed seat 210 and is less prone to damage, thus giving the fan head 10 a longer service life.

[0059] Reference Figure 4 and Figure 6 In some embodiments, the mounting cavity 2211 includes a first cavity segment 22111 and a second cavity segment 22112 that are interconnected. A second driving member 241 is accommodated in the first cavity segment 22111 and abuts against the bottom wall of the first cavity segment 22111. A movable member 242 is accommodated in the second cavity segment 22112. A first opening 2212 connects the accommodating cavity 211 and the second cavity segment 22112. The shape of the first cavity segment 22111 is adapted to the second driving member 241, and the shape of the second cavity segment 22112 is adapted to the movable member 242, so that the second driving member 241 can be positioned by abutting against the bottom wall of the first cavity segment 22111, while reducing the space occupied within the accommodating cavity 211.

[0060] Reference Figures 2 to 4In some embodiments, the head unit 10 further includes a connector assembly 106, and the mounting base 210 is provided with a second opening 214, which connects the accommodating cavity 211 and the external space. The connector assembly 106 passes through the second opening 214 and is connected to the mounting base 210. The connector assembly 106 includes a connector 107, which is electrically connected to the rotating assembly 200 and is used to connect to an external power source. The external power source can be directly connected to the connector 107 via a wire, thereby providing power to the first drive member 111, the second drive member 241, and the panel 101. Furthermore, since the connector 107 assembly is connected to the mounting base 210, the wires used to connect the connector 107 do not need to pass through the inside of the support assembly 400, allowing the support structure to be made of lightweight materials such as plastic, eliminating the need to consider circuit connections and reducing the additional costs caused by circuit connections.

[0061] Reference Figures 4 to 6 In some embodiments, the inner wall of the fixed base 210 is provided with two limiting portions 212. The two limiting portions 212 are spaced apart along the direction of rotation of the rotating member 220 relative to the fixed base 210. The mounting portion 221 includes a first protrusion 2213. The first protrusion 2213 is provided with a second cavity 22112. The first protrusion 2213 is disposed between the two limiting portions 212. The side wall of the first protrusion 2213 away from the second cavity 22112 can abut against the corresponding limiting portion 212 to restrict the rotation of the rotating member 220. Specifically, the central angle of the multiple internal teeth 213 provided on the inner wall of the fixed base 210 is 180°. The two limiting parts 212 are located on the outer side of the internal teeth 213 at both ends along the circumferential direction. When the second driving member 241 drives the movable member 242 to rotate to contact the internal teeth 213 at the end, the first protrusion 2213 abuts against the limiting part 212 to restrict the further rotation of the rotating member 220, so as to prevent the movable member 242 from continuing to rotate and disengaging from the internal teeth 213.

[0062] Reference Figure 6 In some embodiments, the rotating member 220 is further provided with a rotating part 222, which has a second channel 2221 and a third opening 2222. The second channel 2221 communicates with the mounting cavity 2211, and the third opening 2222 communicates with the receiving cavity 211 and the second channel 2221. The connector assembly 106 also includes a wire, one end of which is connected to the connector 107, and the other end of which passes through the third opening 2222 and is connected to the second driving member 241. The third opening 2222 extends circumferentially around the central axis of the second channel 2221, so that when the rotating member 220 rotates relative to the fixed base 210, the sidewall of the third opening 2222 will not cause a large degree of bending to the wire in the rotation direction, thus ensuring the service life of the wire.

[0063] Furthermore, the machine head 10 also includes multiple bearings 103. The rotating part 222 extends away from the second mounting member 230. The bearings 103 are sleeved on the rotating part 222 and abut against the inner wall of the fixed seat 210. The bearings 103 can prevent the rotating part 222 from contacting the fixed seat 210 when rotating relative to it, and at the same time reduce the friction when the rotating part 220 rotates. Specifically, the inner wall of the fixed seat 210 is also provided with multiple steps, each step corresponding to one of the bearings 103, so that when the rotating part 220 is housed in the receiving cavity 211, the relative position of the rotating part 220 and the fixed seat 210 is determined. In addition, the multiple bearings 103 can provide radial force to the rotating part 222, making the rotating part 220 less prone to shaking during rotation and improving the smoothness of operation.

[0064] Furthermore, the inner wall of the fixed base 210 is provided with a clearance groove. Since the third opening 2222 is located below the mounting position of the bearing 103 at the top, the wire needs to extend through the clearance groove to the second channel 2221 to achieve electrical connection between the connector 107 and the second drive assembly 240. Specifically, the clearance groove is located on the side opposite to the internal teeth so that the clearance groove does not affect the rotation of the rotating member 220 relative to the support base 410.

[0065] Reference Figure 1 , Figure 8 and Figure 11 In some embodiments, the fan further includes a grille 440, which is detachably connected to the head unit 10 and covers the outer periphery of the fan blades 20. The grille 440 includes a front cover 441 and a rear cover 442, which are detachably connected. Specifically, the head unit 10 also includes a mounting bracket 105, which is disposed between the mounting base 113 and the first mounting member 120. The rear cover 442 has a fourth opening 4423, through which the mounting bracket 105 passes and is snapped into the rear cover 442. The front cover 441 has a fifth opening 4411, through which the panel 101 passes. When the mesh cover 440 needs to be disassembled, first separate the front cover 441 from the rear cover 442. After removing the front cover 441, remove the fan blade 20 from the mounting base 113. Then, after separating the rear cover 442 from the mounting bracket 105, move it in the direction of the panel 101 to remove the rear cover 442, making both the mesh cover 440 and the fan blade 20 easy to clean and maintain.

[0066] Reference Figure 1 , Figure 8 and Figure 9In some embodiments, the fan further includes a support assembly 400, which includes a support base 410 and a support member 420. The support base 410 includes a first housing 411 and a second housing 412, which are detachably connected. The surfaces of the first housing 411 and the second housing 412 facing each other define a first receiving groove 413. A mounting hole 4111 is provided on the side of the first housing 411 facing away from the first receiving groove 413. The fan has a first state and a second state. In the first state, one end of the support member 420 is mounted in the mounting hole 4111, and the fan head 10 is connected to the other end of the support member 420. (See reference...) Figures 8 to 12 The second housing 412 is provided with a second receiving groove 4121 on the side away from the first receiving groove 413. In the second state, the support member 420 is received in the first receiving groove 413, the fan body is connected to the side of the second housing 412 away from the first receiving groove 413, and the fan head 10 is received in the second state of the second receiving groove 4121. When the fan is in the second state, along the Z-axis direction, the projection of the fan body is located in the projection of the support base 410.

[0067] The first state is the fan's operating state, and the second state is the fan's stored state. When the fan needs to be stored, the support member 420 can be accommodated in the first receiving groove 413, the fan body is connected to the side of the second housing 412 opposite to the first receiving groove 413, and the fan head 10 can be accommodated in the second receiving groove 4121, so that the projection of the fan head 10 along the Z-axis direction is within the projection range of the support base 410 along the Z-axis direction, that is, the fan head 10 will not protrude from the outer side of the support base 410 along the Z-axis direction, thereby reducing the space required for fan storage and making the fan easier to store and transport. The mounting hole 4111 can be provided with an internal thread, and the end of the support rod 421 is provided with an external thread. The end of the support rod 421 is screwed into the mounting hole 4111 to achieve a detachable connection. Alternatively, the mounting hole 4111 can be a through hole, and the second housing 412 facing the surface of the first housing 411 can also have a connecting hole 4126. The sidewall of the mounting hole 4111 surrounds the connecting hole 4126. The end of the support rod 421 has an external thread, and the connecting hole 4126 can have an internal thread. The end of the support rod 421 can be screwed into the connecting hole 4126 to achieve a detachable connection. When the support rod 421 is connected through the connecting hole 4126, the force can be directly transmitted to the second housing 412, avoiding stress at the connection point between the first housing 411 and the second housing 412, thereby extending the service life of the support base 410.

[0068] Furthermore, since the mounting hole 4111 and the second receiving groove 4121 are located on opposite sides of the first housing 411 and the second housing 412 respectively, when the fan is in the first state, the support base 410 supports the support member 420 and the fan body. That is, the end of the first housing 411 away from the first receiving groove 413 faces upward, so that the support member 420 can be connected to the support base 410 through the mounting hole 4111. The second housing 412 faces the ground, and the second receiving groove 4121 is not exposed. Moreover, the end of the first housing 411 away from the first receiving groove 413 is not provided with components such as buckles 4421 or slots 4125 for connecting the fan body, so that the fan is more aesthetically pleasing when in the first state.

[0069] Reference Figure 8 and Figure 11 In some embodiments, a buckle 4421 is provided on the side of the rear cover 442 opposite to the panel, and a slot 4125 is provided on the side of the second housing 412 opposite to the first receiving groove 413, and the buckle 4421 can be engaged with the slot 4125. When the fan is in the second state, the fan body is engaged with the support base 410 by the mesh cover 440, and the support member 420 is housed in the first receiving groove 413, which can achieve a smaller overall size of the fan and facilitate storage.

[0070] In some embodiments, the rear cover 442 is provided with a plurality of buckles 4421, and the second housing 412 is provided with a plurality of slots 4125. Each buckle 4421 corresponds to each slot 4125, so that the buckle 4421 can be engaged with the corresponding slot 4125, thereby improving the stability of the connection between the fan body and the support base 410.

[0071] Reference Figure 10 In some embodiments, the fan further includes a snap-fit ​​member 450 and an elastic member 460. The second housing 412 is also provided with a mounting groove 4122. The snap-fit ​​groove 4125 communicates with the mounting groove 4122 and extends to the outer wall of the second housing 412. The snap-fit ​​member 450 is accommodated in the mounting groove 4122. One end of the snap-fit ​​member 450 is provided with a snap-fit ​​portion 451. The elastic member 460 abuts between the other end of the snap-fit ​​member 450 and the second housing 412. The snap-fit ​​portion 451 corresponds to the snap-fit ​​groove 4125. The buckle 4421 can pass through the snap-fit ​​groove 4125 and snap onto the snap-fit ​​portion 451. The slot 4125 is located on the top wall of the second housing 412. When the latch 4421 is engaged in the slot 4125, the elastic element 460 is compressed to a certain extent, pressing the latching part 451 against the latch 4421 to ensure the stability of the connection between the fan body and the support base 410. When it is necessary to unlock, the spring is further compressed to separate the latching part 451 from the latch 4421. It is understood that the elastic element 460 can be selected as a spring.

[0072] Reference Figure 8 , Figure 9 and Figure 11 In some embodiments, the second housing 412 is further provided with a limiting hole 4123, which communicates with the mounting groove 4122 and extends to the outer wall of the second housing 412. The snap-fit ​​member 450 is further provided with a pressing part 453, which is located on the same side as the snap-fit ​​part 451 and passes through the limiting hole 4123. The limiting hole 4123 can restrict the movement direction of the snap-fit ​​member 450, so that the snap-fit ​​member 450 can only move relative to the support base 410 in a direction perpendicular to the axis of the mounting hole 4111, thus preventing the snap-fit ​​member 450 from deviating. Specifically, the length of the limiting hole 4123 is greater than the movement distance of the snap-fit ​​member 450, so that the snap-fit ​​member 450 will not be dislodged from the limiting hole 4123 when it moves to abut against the groove wall of the mounting groove 4122. When it is necessary to separate the fan body from the support base 410, push the pressing part 453 to move in the direction of compressing the elastic member 460, so that the locking part 451 and the buckle 4421 separate from each other, and then lift the fan body to make the locking part 451 disengage from the slot 4125.

[0073] Reference Figure 9 and Figure 10 In some embodiments, the buckle 4421 has a set width and is provided with a plurality of limiting grooves 4422. The engaging part 451 is provided with a plurality of second protrusions 452. Along the width direction, the plurality of limiting grooves 4422 are spaced apart. Each second protrusion 452 corresponds to each limiting groove 4422. The second protrusion 452 can engage with the limiting groove 4422.

[0074] Specifically, the surface of the second protrusion 452 facing the slot 4125 is inclined. When the latch 4421 abuts against the inclined surface and continues to move downward, the pressure exerted by the latch 4421 on the inclined surface can be decomposed into a downward force in the Z-axis and a horizontal force. The horizontal force can drive the latching member 450 to move and compress the elastic member 460. Subsequently, the side wall of the latch 4421 abuts against the end of the second protrusion 452. When the latch 4421 continues to move downward until the second protrusion 452 corresponds to the limiting groove 4422, the latching member 450 will move under the action of the elastic member 460, causing the second protrusion 452 to engage in the limiting groove 4422, thereby achieving direct fixation between the fan body and the support base 410. The above fixing process is convenient; the user only needs to align the latch 4421 with the slot 4125 and push it downward continuously, without requiring the user to operate the pressing part 453.

[0075] Furthermore, the surface of the buckle 4421 that abuts against the second protrusion 452 is also a slope, and the slope is equal to the slope of the slope provided on the second protrusion 452, making the process of the buckle 4421 moving to engage with the engaging member 450 smoother.

[0076] Reference Figure 8 and Figure 12 In some embodiments, a gripping groove 4124 is also provided on the side of the second housing 412 away from the first receiving groove 413, and the gripping groove 4124 extends toward the first housing 411. When the fan is in the second state, the user can lift and carry the fan as a whole by gripping the gripping groove 4124. Similarly, the gripping groove 4124 and the second receiving groove 4121 are located on the same side of the second housing 412, that is, the side of the fan facing the ground in the first state, to ensure the aesthetics of the fan in the first state.

[0077] Reference Figure 1 and Figure 9 In some embodiments, a support portion 4112 is provided on the side of the first housing 411 opposite to the first receiving groove 413. The support portion 4112 extends circumferentially around the mounting hole 4111 and is generally annular. In the second state, the support portion 4112 can face downwards. In the second state, to prevent the fan body from deforming or being damaged by force, the support portion 4112 supports the entire fan, and it is stored in this posture. The support portion 4112 protrudes from the outer surface of the first housing 411, which can prevent damage or scratches to the outer surface of the first housing 411 when the fan is stored, thereby ensuring the aesthetics of the fan.

[0078] Reference Figure 1 and Figure 9 In some embodiments, the first housing 411 is provided with a plurality of support portions 4112, which are spaced apart along the radial direction of the mounting hole 4111. The support portions 4112 are generally annular, and the radius of the circle corresponding to each support portion 4112 increases sequentially along the radial direction of the mounting hole 4111. When the fan is in the second state, the plurality of support portions 4112 are evenly stressed when supporting the fan, and the fan's posture is more stable when placed in the second state.

[0079] Reference Figure 1 In some embodiments, the support member 420 includes a plurality of support rods 421, which are detachably connected to adjacent support rods 421. Having a plurality of support rods 421 reduces the space requirement of the first receiving slot 413, requiring only that the plurality of support rods 421 be able to be accommodated simultaneously.

[0080] Reference Figure 9In some embodiments, the two ends of the support rod 421 are respectively provided with internal threads and external threads, and adjacent support rods 421 are connected by threaded engagement. The inner wall of the mounting hole 4111 is also provided with internal threads. When installing the support rod 421 onto the support base, one support rod 421 can be screwed into the mounting hole 4111 first, and then the remaining support rods 421 can be connected in sequence, and then the fan body can be connected to the end of the support rod 421 away from the support base 410; or, multiple support rods 421 can be spliced ​​in sequence to form a support member 420, and then connected to the support base 410 and the fan body.

[0081] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
