[0024] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following embodiments are used to illustrate the technical solution of the present invention, but are not intended to limit the scope of protection of the present invention.

[0025] Example:

[0026] like Figures 1 to 6 As shown, the utility model provides a water mist fan with a bearing rotor structure, including a fan housing and a support rod 11. The support rod 11 plays a supporting role in the overall structure, and a mounting sleeve 12 is provided on the top thereof, which provides a basic position for the installation of other components. The bottom of the fan housing is funnel-shaped, which may functionally contribute to the flow of air and the diffusion of water mist. A bearing 21 is provided under the fan housing. The bearing 21 is clamped in the fan housing and sleeved on the support rod 11, so that the mounting sleeve 12 can be stably located in the fan housing, and the fan housing is rotatably connected to the support rod 11 through the bearing 21, which provides a guarantee for the fan's shaking action, ensuring that the shaking action is smoother and more stable.

[0027] An oscillating head assembly is also provided inside the fan housing, further enhancing the fan's functional diversity. At the same time, the support rod 11 is hollow, providing space for the water mist nozzle 22, allowing the water mist nozzle 22 to be smoothly inserted into the support rod 11 and the oscillating head assembly, achieving uniform spraying of water mist. The fan housing is composed of a first housing 31 and a second housing 32, which are detachably connected, facilitating assembly during production and subsequent maintenance and repair work. When it is necessary to inspect, replace, or clean the components inside the fan, the user can easily disassemble the first housing 31 and the second housing 32, improving the convenience and efficiency of operation.

[0028] like Figure 2 、 Figure 3 As shown, the oscillating assembly includes an oscillating disc 41, which is clamped between the first housing 31 and the second housing 32, playing the important role of connection and transmission. Multiple sets of limit posts 33 are provided on the opposing inner sides of the first housing 31 and the second housing 32, and the oscillating disc 41 is correspondingly provided with multiple sets of limit holes 42, with the limit posts 33 passing through the limit holes 42. This not only ensures the stability of the oscillating disc 41 during operation, preventing it from shifting or shaking, but also, through the cooperation of the limit posts 33 and the limit holes 42, the oscillating disc 41 drives the fan housing to rotate, ensuring the accuracy and reliability of the fan's oscillation.

[0029] The oscillating assembly also includes an oscillating motor 43. Inside the fan housing, a mounting plate 13 is located above the mounting sleeve 12. Multiple sets of connecting posts 14 are located at the bottom of the mounting plate 13. The mounting sleeve 12, in turn, has multiple sets of connecting sleeves 15. The connecting posts 14 extend through the connecting sleeves 15, and connecting holes are provided at the bottom of the connecting sleeves 15 and on the connecting posts 14. Connecting screws are locked into the connecting holes, firmly connecting the mounting plate 13 and the mounting sleeve 12 to form a mounting cavity. The oscillating motor 43 is located within this mounting cavity and stably mounted at the bottom of the mounting plate 13.

[0030] The mounting plate 13 is sleeved on the oscillating turntable 41 to form a connecting structure. The oscillating motor 43 is provided with an oscillating gear 44 at the shaft end. The oscillating turntable 41 is provided with two groups of through slots 45. The water mist nozzle 22 is inserted into one group of through slots 45, ensuring the reasonable layout of the water mist nozzle 22 and not affecting the movement of the oscillating turntable 41. The oscillating gear 44 is inserted into the other group of through slots 45. The inner wall of the oscillating turntable 41 is provided with an inner gear ring 46. The length of the inner gear ring 46 is less than the radius of the oscillating turntable 41. The oscillating gear 44 is engaged with the inner gear ring 46. This enables the oscillating motor 43 to accurately drive the oscillating turntable 41 to rotate, realizing the oscillating function of the fan. At the same time, the connecting ring 47 provided in the fan housing is sleeved on the mounting plate 13 and the oscillating turntable 41, further enhancing the structural stability of the entire oscillating assembly, preventing loosening and detachment between components, and ensuring smooth and durable oscillating action.

[0031] like Figure 2 、 Figures 4 to 6 As shown, an adjustable housing 501 is disposed between the first housing 31 and the second housing 32. Multiple sets of fixing posts 35 are provided on the support plates 34 within both the first and second housings 31 and 32, while corresponding sets of fixing sleeves 502 are provided on the adjustable housing 501. The fixing posts 35 are inserted into the fixing sleeves 502 and connected via multiple sets of fixing screws. This not only ensures a secure and reliable connection between the adjustable housing 501 and the fan housing, but also facilitates disassembly. When maintenance, repair, or replacement of the interior of the adjustable housing 501 or related components is required, the user can easily remove the fixing screws. A mounting platform 503 is disposed above the adjustable housing 501. The adjustable housing 501 is connected to the mounting platform 503, which has multiple sets of mounting holes 504. The water mist nozzle 22 is inserted within the adjustable housing 501 and the mounting platform 503, ensuring a reasonable layout and stable installation of the water mist nozzle 22, allowing water mist to be smoothly ejected through the nozzle. This also provides a certain degree of support and fixation for the mounting platform 503.

[0032] Secondly, the adjustment posts 505 on either side of the mounting platform 503 are inserted into the adjustment sleeves 506 on either side of the adjustment housing 501, allowing the mounting platform 503 to be rotatably connected to the adjustment housing 501. This rotatable connection makes it possible to adjust the angle of the fan. Multiple sets of arcuate slots 507 are provided on both sides of the mounting platform 503. Two sets of positioning plates 508 are detachably provided at the bottom of the mounting platform 503. The positioning plates 508 are located below the arcuate slots 507. The positioning plates 508 have positioning holes 509 corresponding to the arcuate slots 507. Two sets of positioning posts 510 are detachably provided within the adjustment housing 501. The tops of the positioning posts 510 are hemispherical in shape. The tops of the positioning posts 510 pass through the positioning holes 509 and are fixed in the arcuate slots 507. The curvature of the arcuate slots 507 is consistent with the curvature of the tops of the positioning posts 510. To adjust the fan's angle, the user manually rotates the mounting platform 503, causing the positioning post 510 to slide within the arc-shaped slot 507. When the desired angle is reached, the positioning post 510 engages the positioning hole 509 and the arc-shaped slot 507, securing the fan's angle. This design allows users to adjust the fan's angle at different angles while ensuring the fan's stability after adjustment.

[0033] The opposing inner sides of the first and second housings 31, 32 are each provided with multiple sets of retaining ribs 36, within which the bearing 21 is retained. The retaining ribs 36 provide precise mounting and retaining action for the bearing 21, preventing displacement or shaking during fan operation, further ensuring overall fan structural stability and operational reliability. This retaining arrangement also facilitates installation and removal of the bearing 21, making maintenance or replacement of the bearing 21 more convenient and efficient.

[0034] The specific usage and function of this embodiment are as follows:

[0035] During use, start the oscillating motor 43. When the oscillating motor 43 is working, the oscillating gear 44 at the end of the shaft will drive the oscillating turntable 41 to rotate. Since the oscillating turntable 41 is clamped between the first shell 31 and the second shell 32, and precise rotation is achieved through the cooperation of the limiting column 33 and the limiting through-hole 42, the oscillating turntable 41 will drive the entire fan shell to oscillate, thereby achieving multi-angle wind blowing. When the water mist function is needed, turn on the water mist generator. If it is an external device, it needs to be connected and turned on separately, and the water mist is sprayed out through the water mist nozzle 22. During the oscillating process, the water mist can also be evenly diffused along the oscillating direction of the fan, thereby achieving cooling and humidification of the surrounding environment.

[0036] To adjust the fan's vertical angle, the user manually moves the mounting platform 503. During this process, the adjustment posts 505 on either side of the mounting platform 503 rotate within the adjustment sleeves 506, while the tops of the positioning posts 510 slide within the arcuate slots 507. Based on actual needs, the mounting platform 503 is rotated to the desired angle. When the tops of the positioning posts 510 reach the desired angle within the arcuate slots 507, the positioning posts 510 engage securely with the positioning holes 509 and the arcuate slots 507, thereby securing the fan's angle and meeting the desired water mist and wind direction requirements in various scenarios.

[0037] The basic principles, main features and advantages of the present invention are shown and described above. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
