Description

Technical Field

[0001] This application relates to the field of heat dissipation technology for electronic devices, and more particularly to an air supply device and an electronic device. Background Technology

[0002] An electric fan, an electrical device that uses a motor to drive fan blades to rotate and circulate air, is primarily used for heat dissipation and air circulation. In electronic devices, such as laptops, fans serve as primary heat dissipation components, designed to cool the internal components to ensure their normal operation and extend their lifespan. However, most current electric fans have fixed blades that cannot be adjusted, limiting their application in certain scenarios. For example, in dusty environments, dust and dirt easily accumulate on the blades, affecting not only the fan's efficiency but also potentially leading to poor heat dissipation and consequently impacting the performance of electronic devices. Because the blades cannot be adjusted, users cannot easily clean them and must rely on manual cleaning. This not only increases the difficulty and workload of maintenance but may also affect the user experience. Summary of the Invention

[0003] In view of the above-mentioned technical problems existing in the prior art, this application provides an air supply device and an electronic device.

[0004] This application provides an air supply device, which includes a mounting frame, an actuation assembly, and multiple fan blades. The actuation assembly includes a drive member, a first transmission member, and a second transmission member. Both the first and second transmission members are mounted on the mounting frame. The drive member is used at least to drive the first transmission member to rotate the mounting frame and to drive the second transmission member to rotate relative to the first transmission member. Multiple fan blades are spaced apart on the mounting frame and rotate with it. Each fan blade includes a connected fan body and a connecting portion. The connecting portion is drively connected to both the first and second transmission members. The second transmission member is used to rotatably drive the fan blades to rotate along the circumferential edge of the first transmission member, causing the fan blades to rotate relative to the first transmission member to adjust the angle of the fan blades.

[0005] In some embodiments, the first transmission member and the second transmission member are respectively disposed on opposite sides of the connecting portion, and the second transmission member drives the connecting portion to rotate along the circumferential edge of the first transmission member.

[0006] In some embodiments, the driving member is at least a first driving member and a second driving member. The first driving member is connected to the first transmission member to drive the mounting bracket and the fan blade to rotate. The second driving member is connected to the second transmission member to drive the fan blade to rotate via the second transmission member.

[0007] In some embodiments, the first transmission member includes a first annular tooth, the second transmission member includes a second annular tooth, the first annular tooth and the second annular tooth are spaced apart vertically, and the connecting portion includes a third annular tooth, the third annular tooth is located between the first annular tooth and the second annular tooth, and meshes with the first annular tooth and the second annular tooth respectively.

[0008] In some embodiments, the air supply device has a first mode and a second mode, wherein the drive member drives the mounting bracket to rotate in a first direction when the air supply device is in the first mode, and drives the mounting bracket to rotate in a second direction when the air supply device is in the second mode; wherein the first direction and the second direction are opposite directions.

[0009] In some embodiments, the fan blade has a first blade surface that faces upward when the air supply device is in a first mode and faces downward when the air supply device is in a second mode.

[0010] In some embodiments, the air supply device further includes a motherboard and a dust detection module. The dust detection module and the driver are electrically connected to the motherboard. The dust detection module is used to detect dust information related to the fan blades. The motherboard is used to receive the dust information and send a control command to the air supply device to switch it from the first mode to the second mode.

[0011] In some embodiments, the motherboard is specifically used to control the drive component to stop driving the mounting bracket to rotate in the first direction, and to control the drive component to drive the first blade surface of the fan blade to rotate from facing upward to facing downward through the second transmission component, and then drive the mounting bracket to rotate in the second direction through the first transmission component.

[0012] In some embodiments, the air supply device further includes an electrically connected slip ring and a main board, the slip ring being sleeved outside the output shaft of the first drive member, and the main board supplying power to the second drive member through the slip ring.

[0013] This application also provides an electronic device, including the air supply device described above.

[0014] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: When the driving component of the air supply device of this application drives the first transmission component to rotate the mounting bracket, it drives multiple fan blades to rotate synchronously to generate a stable airflow. After dust and dirt accumulate on the fan blades, the driving component can drive the second transmission component to rotate, so that multiple fan blades rotate along the circumferential edge of the first transmission component. This can drive the first transmission component to rotate again, thereby driving multiple fan blades to rotate synchronously to shake off the dust and dirt. When the air supply device is installed on electronic equipment, it can not only deliver airflow into the electronic equipment to reduce the temperature of the components inside the electronic equipment and ensure the performance and service life of the components, but also shake off the dust and dirt without user intervention. This not only avoids the impact of dust and dirt on the fan blades and ensures the air supply efficiency of the air supply device, but also effectively reduces the maintenance difficulty and workload of the air supply device and improves the user experience of the electronic equipment. In addition, due to its compact structure and reasonable layout, the air supply device can be applied to small electronic equipment, effectively improving its practicality and applicability.

[0022] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0023] This application provides an air supply device, such as... Figures 1 to 5As shown, the air supply device includes a mounting frame 1, an actuation assembly 2, and multiple fan blades 3. The actuation assembly 2 includes a drive member 21, a first transmission member 22, and a second transmission member 23. Both the first transmission member 22 and the second transmission member 23 are mounted on the mounting frame 1. The drive member 21 is used at least to drive the first transmission member 22 to rotate the mounting frame 1 and to drive the second transmission member 23 to rotate relative to the first transmission member 22. Multiple fan blades 3 are spaced apart on the mounting frame 1 and rotate with it. Each fan blade 3 includes a connected fan body 31 and a connecting portion 32. The connecting portion 32 is drively connected to both the first transmission member 22 and the second transmission member 23. The second transmission member 23 rotatably drives the fan blades 3 to rotate along the circumferential edge of the first transmission member 22, causing the fan blades 3 to rotate relative to the first transmission member 22, thereby adjusting the angle of the fan blades 3.

[0024] The aforementioned mounting frame 1 can be constructed as a frame structure, and the actuation component 2 and multiple fan blades 3 can be mounted on the mounting frame 1, thereby enabling the dispersed functional components to form a compact and rationally arranged whole.

[0025] The aforementioned multiple fan blades 3 can be arranged at intervals along the circumference of the mounting frame 1 on the mounting frame 1. The fan body 31 of each fan blade 3 can be located on the outer side of the mounting frame 1. The connecting part 32 of each fan blade 3 can be inserted into the mounting frame 1 and connected to the first transmission member 22 and the second transmission member 23.

[0026] The aforementioned first transmission component 22 can be connected to the mounting bracket 1. Specifically, the first transmission component 22 and the mounting bracket 1 can be detachably connected or integrally formed. Detachable connection can include snap-fit ​​connection or adhesive connection, etc., which are not specifically limited in this application. Preferably, the first transmission component 22 and the mounting bracket 1 are integrally formed to improve the connection strength between the first transmission component 22 and the mounting bracket 1.

[0027] The aforementioned driving component 21 can be connected to the first transmission component 22. When the driving component 21 drives the first transmission component 22 to rotate, it can drive the mounting frame 1 and multiple fan blades 3 to rotate synchronously. The driving component 21 can also be connected to the second transmission component 23. When the driving component 21 drives the second transmission component 23 to rotate, the second transmission component 23 can drive multiple fan blades 3 to rotate synchronously, thereby adjusting the angle of the fan blades 3.

[0028] The angle of the aforementioned fan blade 3 can be specifically expressed as the tilt angle of the fan blade 3 relative to the horizontal plane. It can be understood that this angle can at least affect the direction and efficiency of the airflow formed when the fan blade 3 rotates.

[0029] The upper part of the aforementioned mounting frame 1 can be open, and the second transmission component 23 can be installed inside the mounting frame 1 through the aforementioned opening. The air supply device may also include a cover plate 7 fastened to the mounting frame 1. The cover plate 7 can cover the mounting frame 1, thereby ensuring the stability and reliability of the second transmission component 23 when it rotates.

[0030] A ball bearing 8 can be provided between the second transmission member 23 and the cover plate 7. Multiple balls bearing 8 can be evenly arranged along the circumferential direction of the second transmission member 23. In this way, the cover plate 7 can apply a resisting force to the second transmission member 23 through the multiple balls bearing 8, ensuring the stability of the second transmission member 23 during rotation. Furthermore, the balls bearing 8 can reduce the friction between the second transmission member 23 and the cover plate 7, thereby ensuring the driving efficiency of the drive member 21.

[0031] The drive unit 21 of the air supply device in this application can drive the first transmission unit 22 to rotate the mounting bracket 1, thereby causing multiple fan blades 3 to rotate synchronously to generate a stable airflow. When dust and dirt accumulate on the fan blades 3, the drive unit 21 can drive the second transmission unit 23 to rotate, causing the multiple fan blades 3 to rotate along the circumferential edge of the first transmission unit 22. This allows the first transmission unit 22 to rotate again, causing the multiple fan blades 3 to rotate synchronously and dislodge the dust and dirt. When the air supply device is installed on electronic equipment, it not only delivers airflow into the electronic equipment, thereby reducing the temperature of the components and ensuring their performance and lifespan, but also dislodles dust and dirt without user intervention. This not only prevents dust and dirt from affecting the fan blades 3 and ensures the air supply efficiency of the device, but also effectively reduces the maintenance difficulty and workload of the air supply device, improving the user experience of the electronic equipment. Furthermore, due to its compact structure and reasonable layout, the air supply device can be applied to small electronic devices, effectively improving its practicality and applicability.

[0032] In some embodiments, such as Figures 1 to 5 As shown, the first transmission member 22 and the second transmission member 23 are respectively located on opposite sides of the connecting part 32. The second transmission member 23 drives the connecting part 32 to rotate along the circumferential edge of the first transmission member 22.

[0033] In this way, when the first transmission component 22 rotates, it can drive the second transmission component 23 and the fan blade 3 to rotate synchronously. When the second transmission component 23 rotates, it can drive the connecting part 32 of the fan blade 3 to rotate along the circumferential edge of the first transmission component 22, thereby realizing the angle adjustment of each fan blade 3. This structural layout effectively simplifies the structure of the air supply device and improves the rationality of the structural layout of the air supply device.

[0034] like Figure 2As shown, the first transmission member 22 and the second transmission member 23 can both be disc-shaped. The disc-shaped first transmission member 22 and the second transmission member 23 can be arranged at intervals along the vertical direction. The connecting part 32 of the fan blade 3 can be rotatably connected to the first transmission member 22 and the second transmission member 23 respectively. When the driving member 21 drives the second transmission member 23 to rotate, the second transmission member 23 can drive the connecting part 32 of each fan blade 3 to rotate along the circumferential edge of the first transmission member 22, thereby realizing the angle adjustment of the fan blade 3.

[0035] In some embodiments, such as Figures 1 to 5 As shown, the driving component 21 is at least a first driving component 211 and a second driving component 212. The first driving component 211 is connected to the first transmission component 22 to drive the mounting frame 1 and the fan blade 3 to rotate. The second driving component 212 is connected to the second transmission component 23 to drive the fan blade 3 to rotate.

[0036] Thus, the first drive component 211 can be used to drive the mounting frame 1 and the fan blades 3 to rotate, thereby achieving the overall rotation of multiple fan blades 3. The second drive component 212 can be used to drive each fan blade 3 to rotate, thereby achieving angle adjustment of each fan blade 3. It is understood that the rotation of the fan blades 3 with the mounting frame 1 and the rotation of the fan blades 3 are not simultaneous, but separate processes. Through the independent operation and coordinated cooperation of the two drive components 21, the air supply device can meet different usage scenarios and needs, effectively improving the flexibility of the air supply device.

[0037] like Figure 5 As shown, the output shaft of the first drive member 211 can be connected to the lower wall of the first transmission member 22. When the output shaft of the first drive member 211 rotates, it can drive the first transmission member 22 to rotate, thereby driving the mounting bracket 1 connected to the first transmission member 22 and the multiple fan blades 3 located on the mounting bracket 1 to rotate synchronously.

[0038] like Figure 6 As shown, the upper wall of the first transmission member 22 can be recessed inward to form a placement position 222 for placing the second driving member 212. The second driving member 212 can be placed in the placement position 222, and the output shaft of the second driving member 212 can be connected to the second transmission member 23. Thus, when the output shaft of the second driving member 212 rotates, it can drive the second transmission member 23 to rotate relative to the first transmission member 22.

[0039] In some embodiments, such as Figures 1 to 7As shown, the first transmission component 22 includes a first annular tooth 221, the second transmission component 23 includes a second annular tooth 231, the first annular tooth 221 and the second annular tooth 231 are arranged vertically at intervals, and the connecting part 32 includes a third annular tooth 321, the third annular tooth 321 is located between the first annular tooth 221 and the second annular tooth 231, and meshes with the first annular tooth 221 and the second annular tooth 231 respectively.

[0040] Thus, the third annular tooth 321 can be located between the first annular tooth 221 and the second annular tooth 231, and mesh with the first annular tooth 221 and the second annular tooth 231 respectively. When the driving force generated by the second driving member 212 acts on the second transmission member 23, it can make the second transmission member 23 rotate smoothly and stably relative to the first transmission member 22, effectively ensuring the stability of the operation of the air supply device.

[0041] The first annular tooth 221 can be disposed on the upper wall surface of the first transmission member 22 along the circumference of the first transmission member 22, the second annular tooth 231 can be disposed on the lower wall surface of the second transmission member 23 along the circumference of the second transmission member 23, and the third annular tooth 321 can be disposed on the connecting part 32 along the circumference of the connecting part 32. Thus, when the connecting part 32 is located between the first transmission member 22 and the second transmission member 23, the third annular tooth 321 can mesh with the first annular tooth 221 and the second annular tooth 231 respectively.

[0042] In some embodiments, the air supply device has a first mode and a second mode. When the air supply device is in the first mode, the drive member 21 drives the mounting bracket 1 to rotate in a first direction, and when the air supply device is in the second mode, the drive member 21 drives the mounting bracket 1 to rotate in a second direction; wherein the first direction and the second direction are opposite directions.

[0043] In this way, the air supply device can flexibly switch between the first mode and the second mode according to actual usage needs, thus adapting to different usage scenarios and needs, significantly improving the adaptability and flexibility of the air supply device.

[0044] The aforementioned air supply device can have a first mode and a second mode. The first mode can be a heat dissipation mode, where the first drive component 211 rotates the mounting bracket 1 in a first direction, causing the multiple fan blades 3 on the mounting bracket 1 to rotate as a whole to generate an airflow. The second mode can be a dust removal mode, where each fan blade 3 can be adjusted at an angle, putting the air supply device in the second mode. In this mode, the first drive component 211 rotates the mounting bracket 1 in a second direction, thus dislodging dust and dirt from the multiple fan blades 3. Furthermore, when the air supply device is installed on the side wall of an electronic device, the air supply device in the second mode can generate a dust removal airflow, blowing out dust and dirt from inside the electronic device for comprehensive cleaning.

[0045] The first and second directions mentioned above can be represented as opposite directions of rotation, rather than fixed directions of rotation. Specifically, when the first direction is clockwise, the second direction can be counterclockwise. Conversely, when the first direction is counterclockwise, the second direction can be clockwise.

[0046] In some embodiments, the fan blade 3 has a first blade surface, which is arranged upward when the air supply device is in a first mode and downward when the air supply device is in a second mode.

[0047] In this way, the first blade of fan blade 3 can be matched with different modes of the air supply device, thereby ensuring that fan blade 3 can generate sufficient air volume when rotating, and ensuring that the air supply device can achieve a relatively ideal performance in both the first and second modes.

[0048] The aforementioned fan blade 3 may also have a second blade disposed opposite to the first blade. When the air supply device is in the first mode, the first blade may be disposed upwards, while the second blade may be disposed downwards. Similarly, when the air supply device is in the second mode, the first blade may be disposed downwards, while the second blade may be disposed upwards.

[0049] It can be understood that the first blade can have a certain tilt angle. When the fan blade 3 rotates under its drive, the first blade can push against the surrounding air at the aforementioned tilt angle, thereby allowing the air to flow in a fixed direction and ultimately forming a continuous airflow. When the air supply device is in the first mode, the first blade can be set upwards to generate an airflow. When the air supply device is in the second mode, the first blade can be set downwards to generate a dust removal airflow.

[0050] In some embodiments, such as Figure 8As shown, the air supply device also includes a main board 4 and a dust detection module 5. The dust detection module 5 and the driver 21 are electrically connected to the main board 4. The dust detection module 5 is used to detect dust information related to the fan blade 3. The main board 4 is used to receive the dust information and send a control command to the air supply device to switch it from the first mode to the second mode.

[0051] Thus, after the dust detection module 5 detects relevant dust information on the fan blade 3, the motherboard 4 can receive the dust information and control the air supply device to switch from the first mode to the second mode, thereby realizing the automatic dust removal of the fan blade 3, effectively improving the automation level of the air supply device and the ease of use.

[0052] The aforementioned motherboard 4 can be constructed using electronic components such as timers, comparators, registers, and digital logic circuits, or implemented using processor chips such as microcontrollers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs), programmable logic arrays (PLAs), and application-specific integrated circuits (ASICs) and their peripheral circuits.

[0053] The aforementioned dust detection module 5 can be used to monitor the amount of dust on the fan blades 3 in real time. When the amount of dust on the fan blades 3 reaches a preset dust level, dust information can be generated. It is understood that the preset dust level can be determined based on the operating environment and needs of the air supply device, and this application does not impose any specific limitations on it.

[0054] In some embodiments, the motherboard 4 is specifically used to control the drive unit 21 to stop driving the mounting bracket 1 to rotate in the first direction, and to control the drive unit 21 to drive the first blade surface of the fan blade 3 to rotate from facing upward to facing downward through the second transmission member 23, and then drive the mounting bracket 1 to rotate in the second direction through the first transmission member 22.

[0055] Thus, when the dust detection module 5 detects dust information related to the fan blade 3, the main board 4 can control the drive component 21 to stop rotating the mounting bracket 1 in the first direction, and by controlling the flipping of the first blade and the rotation of the mounting bracket 1 in the second direction, the dust on the fan blade 3 can be automatically cleaned. In this way, through the orderly control and connection of the main board 4, the cleanliness of the fan blade 3 is ensured, and the automation level and ease of use of the air supply device are greatly improved.

[0056] The following describes the operation of the air supply device: The dust detection module 5 can detect the dust information related to the fan blades 3 in real time. When the dust information on the fan blades 3 is less than the preset dust amount, the main board 4 can control the first drive component 211 to drive the mounting bracket 1 to rotate in the first direction, so that the mounting bracket can drive multiple fan blades 3 to rotate synchronously. At this time, the air supply device can be in the first mode. When the dust information on the fan blades 3 is greater than or equal to the preset dust amount, the main board 4 can control the first drive component 211 to stop driving the mounting bracket 1 to rotate in the first direction, and control the second drive component 212 to drive the fan blades 3 to rotate, so that the first blade surface of the fan blades 3 rotates from facing upward to facing downward. Then the main board 4 can again control the first drive component 211 to drive the mounting bracket 1 to rotate in the second direction, so that the air supply device is in the second mode.

[0057] In some embodiments, such as Figures 1 to 5 As shown, the air supply device also includes a collector ring 6 and a main board 4 that are electrically connected. The collector ring 6 is sleeved outside the output shaft of the first drive unit 211, and the main board 4 supplies power to the second drive unit 212 through the collector ring 6.

[0058] In this way, the mainboard 4 can supply power to the second drive unit 212 through the collector ring 6 without the need for additional wires, thereby avoiding the occurrence of wire tangling during the rotation of the mounting bracket 1, effectively reducing failures and downtime caused by wire tangling, and ensuring the smooth operation of the air supply device.

[0059] The aforementioned slip ring 6 can be used to transfer current between a rotating body and a stationary body, that is, to transfer current between the main board 4 and the second drive component 212. The slip ring 6 can be made of a ring-shaped conductive material, which can maintain the continuity of current during rotation.

[0060] This application also provides an electronic device, including the air supply device described above.

[0061] When the drive unit 21 of the electronic device using the above-mentioned air supply device drives the first transmission unit 22 to rotate the mounting bracket 1, it drives multiple fan blades 3 to rotate synchronously to generate a stable airflow. After dust and dirt accumulate on the fan blades 3, the drive unit 21 can drive the second transmission unit 23 to rotate, causing the multiple fan blades 3 to rotate along the circumferential edge of the first transmission unit 22. This allows the first transmission unit 22 to rotate again, causing the multiple fan blades 3 to rotate synchronously and shake off the dust and dirt. When the air supply device is installed on the electronic device, it not only delivers airflow into the device, reducing the temperature of the components and ensuring their performance and lifespan, but also shakes off dust and dirt without user intervention. This not only prevents dust and dirt from affecting the fan blades 3 and ensures the air supply efficiency of the device, but also effectively reduces the maintenance difficulty and workload of the device, improving the user experience. Furthermore, due to its compact structure and reasonable layout, the air supply device can be applied to small electronic devices, effectively improving its practicality and applicability.
