[0025] Please see Figures 1 to 5 The illustrated oscillating drive mechanism with a protective cover includes a drive component 2 connected to a main unit 1, a transmission component 4 connected to a support 3, and a protective cover 5 connected to the main unit 1 and fitted onto the drive component 2 and the transmission component 4. The drive component 2 and the transmission component 4 are connected in cooperation, and the drive component 2 drives the main unit 1 to rotate relative to the support 3.

[0026] In this invention, the main unit 1 is the main component of the fan, housing the fan control module, the fan blade drive mechanism for rotating the blades, and the oscillation drive mechanism, among other components. The support 3 serves as the support for the entire fan. The main unit 1 and the support are connected via the oscillation drive mechanism. Furthermore, the oscillation drive mechanism includes a drive assembly 2 and a transmission assembly 4. The drive assembly 2 is directly connected to the main unit 1 and serves as the power source for the oscillation drive mechanism. The transmission mechanism 4 is directly connected to the support 3 and is responsible for transmitting the rotational power of the drive mechanism 2. When the oscillation drive mechanism operates... When in motion, the power of the drive component 2 is transmitted to the transmission component 4, and the support 3 connected to the transmission component 4 remains stationary. The drive component 2 drives the main unit 1 to rotate relative to the support 3 under its own power, thereby realizing the oscillation function of the fan. Furthermore, by setting a protective cover 5 that is fitted over the drive component 1 and the transmission component 4, dust, lint and other debris in the air can be effectively isolated to prevent them from entering between the drive component 1 and the transmission component 5, reducing the risk of jamming, abnormal noise or inability to oscillate between the drive component 1 and the transmission component 5, and effectively improving the reliability and safety of the oscillation drive mechanism.

[0027] Furthermore, the drive assembly 2 includes a swaying drive motor 21 connected to the host 1 and a drive gear 22 connected to the swaying drive motor 21. The transmission assembly 4 includes a fixed shaft 41 connected to the support 3 and a fixed gear 42 connected to the fixed shaft 41. The drive gear 22 meshes with the fixed gear 42. The swaying drive motor 21 drives the drive gear 22 to rotate, so that the host 1, which is fixedly connected to the drive gear 22, rotates relative to the support 3. The protective cover 5 is sleeved on the drive gear 22 and the fixed gear 42.

[0028] In this invention, the drive assembly 2 specifically includes a oscillating drive motor 21 connected to the main unit 1 and a drive gear connected to the oscillating drive motor 21. The transmission assembly 4 specifically includes a fixed shaft 41 connected to the support 3 and a fixed gear 42 connected to the fixed shaft 41. The drive gear 22 is fixed on the output shaft of the oscillating drive motor and meshes with the fixed gear 42. Since the fixed gear 42 is stationary, the rotation of the drive gear 22 is converted into an oscillating motion of the main unit 1 relative to the support 3. Furthermore, the protective cover 5 is fitted over the drive gear 22 and the fixed gear 42. This design not only prevents dust, lint, and other debris from entering the gear meshing area but also prevents the lubricating oil of the drive gear 22 and the fixed gear 42 from splashing outwards, thus improving the safety and service life of the fan.

[0029] Furthermore, the drive gear 22 and the fixed gear 42 are located inside the host 1. The protective cover 5 is provided with a mounting cavity to accommodate the drive gear 22 and the fixed gear 42. The protective cover 5 is sleeved on the upper side of the drive gear 22 and the fixed gear 42. The lower side of the host 1 is provided with a mounting hole 6. The fixed shaft 41 passes through the mounting hole 6 and connects to the fixed gear 42 inside the host 1.

[0030] Existing fans typically house the drive gear and fixed gear on the support, separating them from other electrical components to prevent interference between these components and the oscillation drive mechanism. In this invention, however, the drive gear 22 and fixed gear 42 are integrated with other components within the main unit 1, effectively improving the fan's structural compactness and overall integrity. The protective cover 5 has a dedicated mounting cavity to accommodate the drive gear 22 and fixed gear 42, allowing it to fit over the drive gear 22 and fixed gear 42, forming a closed or semi-closed space to prevent dust, lint, and other debris from entering. The protective cover 5 effectively solves the problem of interference that easily occurs when the drive gear 22 and the fixed gear 42 are placed inside the main unit 1. Since the drive gear 22 and the fixed gear 42 are placed inside the main unit 1, the protective cover 5 can also prevent the wires inside the main unit 1 from being caught in the gear meshing area, effectively improving the safety of the fan. Furthermore, the main unit 1 has a mounting hole 5 on its lower side for the fixed shaft 41 to pass through and connect with the fixed gear 42. The mounting hole 5 allows the fixed shaft 41 to pass through the main unit 1 and connect with the fixed gear 42, ensuring the feasibility of connecting the fixed gear 42 and the fixed shaft 41.

[0031] Furthermore, the mounting hole 6 is provided with a first extension 61 extending into the host 1 on its periphery, and a bearing 7 connecting the first extension 61 and the fixed shaft 41 is provided between the two. The first extension 61 is provided with a first mounting groove 611 for mounting the bearing 7.

[0032] In this utility model, the first extension 61 is disposed on the periphery of the mounting hole 6 and extends into the host 1, providing mounting space for the bearing 7 and enhancing the connection stability between the host 1 and the fixed shaft 41. Furthermore, the first mounting groove 611 is disposed on the first extension 61 for fixing the bearing 7. The bearing 7 is installed between the first extension 61 and the fixed shaft 41 to reduce the friction between the two and improve the rotation efficiency.

[0033] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the first mounting groove 611 is provided with a plurality of protrusions 6111 evenly distributed along its sidewall. The protrusions 6111 are used to fit tightly with the bearing 7, thereby enhancing the friction between the first mounting groove 611 and the bearing 7, so that the bearing 7 is engaged in the first mounting groove 611, effectively improving the connection stability and reliability between the bearing 7 and the first mounting groove 611.

[0034] Furthermore, the fixed gear 42 is provided with a wire hole 421, and the protective cover 5 is provided with a second extension 51 extending toward the fixed gear 42 and passing through the wire hole 421. The second extension 51 is provided with a connection hole 511 for the wire to pass through.

[0035] In this invention, the wire hole 421 is provided on the fixed gear 42 to guide the wires inside the host 1 through, preventing the wires from interfering with the transmission component 4 or being caught in the gear meshing area. The second extension 51 extends from the protective cover 5 toward the fixed gear 42 and passes through the wire hole 421 on the fixed gear 42, providing a safe passage for the wires. Specifically, the second extension 51 extends into the wire hole 421, and the wires inside the host 1 pass through the connection hole 511 and the wire hole 421 at the same time, and finally connect to the power cord provided on the support 3. This design realizes the electrical connection between the electrical components inside the host 1 and the power cord provided on the support 3, while ensuring that the wires will not be caught in the meshing area of ​​the drive gear 22 and the fixed gear 42, effectively improving the safety and reliability of the fan.

[0036] Furthermore, the host 1 is provided with a first connecting part 11 inside, and the protective cover 5 is provided with a first mating part 52. The first connecting part 11 and the first mating part 52 are mated together to fix the protective cover 5 to the host 1.

[0037] In this utility model, the first connecting part 11 is disposed inside the host 1 and is used to connect with the first mating part 52 on the protective cover 5. The connection between the first connecting part 11 and the first mating part 52 can be fixed by means of snap-fit ​​connection, threaded connection or interference fit. This design can ensure the stability and reliability of the connection between the protective cover 5 and the host 1, while also being convenient to install and disassemble, so that users can perform maintenance.

[0038] Furthermore, the oscillating drive mechanism with a protective cover includes a conductive ring for connecting the control module and the power cord. The control module is located on the host 1, the power cord is located on the support 3, and the fixed shaft 41 has a second mounting groove 411 for mounting the conductive ring on the side near the fixed gear 42.

[0039] In this invention, the conductive ring is used to connect the control module inside the host 1 to the power cord on the support 3. The conductive ring consists of a rotor in a rotating part and a stator in a fixed part. The rotor is equipped with a conductive metal ring, and the stator is equipped with brushes. When the host 1 rotates, the rotor drives the conductive metal ring to rotate. The brushes and the conductive metal ring continuously slide in contact, forming a stable current path. This ensures that the power supply and signal transmission remain continuous when the host 1 rotates relative to the support 3. In addition, the design of the conductive ring solves the problem of wire entanglement caused by the rotation of the host 1, allowing the host 1 to rotate 360° without being restricted by the wire entanglement problem. This effectively improves the practicality and functionality of the fan. The fixed shaft 41 is hollow, so that the wire can pass through the inside of the fixed shaft 41, avoiding the wires from running outside the fan and improving the aesthetics of the fan.

[0040] Furthermore, there are two first mounting slots 611, one on the side of the first extension 61 near the fixed gear 42 and the other on the side near the support 3, and the bearing 7 is provided in a one-to-one correspondence with the first mounting slot 611.

[0041] In this invention, by providing first mounting grooves 611 on the side of the first extension 61 near the fixed gear 42 and on the side near the support 3, and correspondingly providing bearings 7 that cooperate with them, this double bearing design not only reduces the friction between the first extensions 61 of the fixed shaft 41 and improves the transmission efficiency, but also reduces the noise during the transmission process, making the fan run more quietly. In addition, it further improves the rotational stability between the fixed shaft 41 and the host 1, effectively distributing the load and reducing the pressure on a single bearing, thereby improving the stability and reliability of the overall structure.

[0042] The fan includes the aforementioned oscillation drive mechanism with a protective cover, a main unit 1, and a support 3. The oscillation drive mechanism with the protective cover is used to connect the main unit 1 and the support 3.

[0043] In this invention, the fan, by integrating the oscillating drive mechanism with a protective cover, can effectively isolate dust, lint, and other debris in the air from entering between the drive component 1 and the transmission component 5, reducing the risk of jamming, abnormal noise, or inability to oscillate between the drive component 1 and the transmission component 5, and effectively improving the reliability and safety of the oscillating drive mechanism.

[0044] Furthermore, the fan includes a fan blade drive motor and a control module disposed within the main unit 1, and fan blades connected to the fan blade drive motor.

[0045] In this invention, the control module is electrically connected to the fan blade drive motor and the oscillation drive mechanism respectively, and is used to control their start and stop. The fan integrates the fan blade drive motor and the oscillation drive motor into the main unit 1 by setting the fan blade drive motor in the main unit 1. This design effectively improves the compactness of the fan structure. The design of the protective cover 5 can effectively avoid mutual interference caused by the integration of the fan blade drive motor and the oscillation drive mechanism into the main unit 1, effectively prevent debris that may be generated by the fan blade drive motor during operation from entering the oscillation drive mechanism, and also avoid jamming or damage caused by interference between the wires and the oscillation drive mechanism, thereby improving the structural rationality and safety of the fan.
