[0028] In the embodiment provided in the utility model, the motor support 51 is provided with a driving motor 7, and the driving motor 7 drives the fan head 1 to rotate.

[0029] The wall fan is designed to realize the expansion of the air supply range and the more extensive air circulation effect by combining the left-right swing head adjusting mechanism 4 with the up-down swing head structure 5.

[0030] Specifically, the wall fan base 2 is usually installed on the wall to provide stable support. The fan head 1 contains the fan blades and their driving motor, responsible for generating airflow. The foot stand bracket 3 is located between the wall fan base 2 and the fan head 1, not only serving as support, but also housing the rotating shaft 31. The rotating shaft 31 is set inside the foot stand bracket 3 and is the core component for realizing the swing of the fan head 1. The left and right swing adjustment mechanism 4 is set in the wall fan base 2, used to drive the rotating shaft 31 to rotate, so that the fan head 1 can swing in the horizontal direction relative to the wall fan base 2. The up and down swing structure 5 is rotatably connected to the fan head 1 at one end and is in interference fit with the rotating shaft 31 at the other end. This structure allows the fan head 1 to swing in the vertical direction relative to the wall fan base 2.

[0031] The left and right swing adjustment mechanism 4 drives the rotating shaft 31 to rotate, so that the fan head 1 can swing in the horizontal direction, thereby covering a larger area. The up and down swing structure 5 is responsible for swinging the fan head 1 in the vertical direction (e.g. 90 degrees), further expanding the air supply range. This action is also achieved through cooperation with the rotating shaft 31.

[0032] The application combines automatic swing functions in horizontal and vertical directions, can realize air supply in three-dimensional space, greatly improves air supply efficiency and comfort. Placing the left and right swing adjustment mechanism 4 inside the wall fan base 2 and using the foot stand bracket 3 to accommodate the rotating shaft 31 helps to maintain the compactness of the overall design and reduce the occupied space. The interference fit between the up and down swing structure 5 and the rotating shaft 31 ensures the firmness of the connection and the accuracy of the operation, which helps to improve the stability and durability of the system.

[0033] The application achieves flexible movement of the fan head 1 in multiple dimensions by ingeniously integrating various mechanical structures, significantly improving the air supply range and effect. Such design is particularly suitable for environments that require large-area ventilation or temperature regulation, such as large offices, conference rooms, or living rooms in homes, etc.

[0034] Through the up and down swing structure 5, the automatic swing of 90 degrees up and down and wide angle left and right is realized, which can cover a larger area to ensure good ventilation in all parts of the room. The design of placing the left and right swing adjustment mechanism 4 at the bottom of the wall fan base 2 helps to reduce the space required for the fan head 1 part, making the overall structure more compact.

[0035] Automatic up and down and left and right swing reduces the need for manual adjustment, especially suitable for high installation scenarios, improving the convenience of use. For users, such design not only provides better functionality, but also increases flexibility and comfort when using.

[0036] The fan head 1 can be automatically swung in the vertical direction by the up-and-down swinging structure 5 in the present application. The motor support 51 is installed on the fan head 1 and is provided with fixing seats 52 on both sides thereof, which are firmly connected with the motor support 51.

[0037] The motor support 51 not only provides a mounting platform for other components, but also ensures the stability of the overall structure.

[0038] The fixing seats 52 are provided on both sides of the motor support 51 and are firmly connected therewith. The fixing seats 52 not only serve to support the iron support 50, but also are respectively provided with a bushing 57 at the end of each support facing the iron support 50, so as to ensure that the movable shaft 53 installed at the front end of the iron support 50 can be flexibly rotated. The design of the iron support 50 needs to consider the strength and stability to withstand the action of the first driving motor 54 and the connecting shaft 31.

[0039] The movable shaft 53 is installed on the iron support 50 and is movably connected with the fixing seat 52 through the bushing 57. One end of the movable shaft 53 is installed with a large gear 56, and the first driving motor 54 is installed on the iron support 50, with a small gear 55 installed on the output shaft thereof. The large gear 56 is engaged with the small gear 55, and when the first driving motor 54 works, it will drive the small gear 55 to rotate, thereby driving the large gear 56 and the movable shaft 53 to swing up and down relative to the wall fan seat 2. This gear transmission mode can effectively convert the rotary motion of the first driving motor 54 into the up-and-down swinging motion of the fan head 1.

[0040] The two ends of the limiting piece 59 are fixed on the iron support 50, and the middle part is provided with a limiting hole 590. One end of the small gear 55 is sleeved in the limiting hole 590, so as to limit the swinging angle and prevent the small gear 55 on the output shaft of the first driving motor 54 from being skewed due to excessive swinging.

[0041] The tail end of the iron support 50 is fixedly connected with the rotating shaft 31, so as to ensure that the entire up-and-down swinging structure 5 is closely combined with the overall frame of the wall fan, so that the up-and-down swinging motion is more stable and reliable.

[0042] When the second driving motor 41 is started, the small gear 55 on the output shaft thereof begins to rotate. The small gear 55 transmits the rotary force to the movable shaft 53 through the meshing action with the large gear 56 on the movable shaft 53. The movable shaft 53 is then rotated, thereby driving the fan head 1 to swing up and down relative to the wall fan seat 2.

[0043] By reasonably designing the ratio of the pinion gear 55 and the gear wheel 56, the speed and angle of oscillation can be controlled to achieve the best air supply effect. This design fully utilizes the advantages of gear transmission, realizes the automatic oscillation of the fan head 1 in the vertical direction, greatly expands the air supply range, improves the air circulation efficiency, and enhances the user experience. In order to further improve the reliability and safety of the system, it is recommended to add appropriate limiting devices and other protective measures in the design.

[0044] The second drive motor 41 is installed inside the wall fan base 2 through the mounting bracket 6. The output shaft of the second drive motor 41 is provided with a first gear 44. When the motor is started, the first gear 44 is driven to rotate by the motor, and the first gear 44 drives the second gear 43 to rotate through the interaction force between the teeth. Since the second gear 43 is directly connected or fixed to the bottom of the rotating shaft 31, the rotation of the second gear 43 will cause the rotating shaft 31 to rotate relative to the wall fan base 2. This realizes the left and right oscillation function of the fan head 1 part.

[0045] In order to ensure the stability of the entire wall fan and reduce the vibration that may occur during operation, the mounting bracket 6 and the mounting column are added in the design. The mounting bracket 6 is provided with a mounting hole 61, and the wall fan base 2 is provided with a mounting column. The fixing holes 45 on both sides of the second drive motor 41 pass through the mounting column together with the mounting hole 61 and are fixed thereon, ensuring the stability of the motor and the entire oscillation mechanism.

[0046] The left and right head adjustment mechanism 4 of the wall fan utilizes the second drive motor 41 as a power source, and transmits the rotary motion to the rotating shaft 31 through the cooperation of the first gear 44 and the second gear 43, so that the fan can oscillate left and right.

[0047] The wall fan base 2 is also provided with a PCB board 21, and the PCB board 21 is provided with an LED lamp plate and a lampshade 22.

[0048] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principles of the present application shall be included in the protection scope of the present application.
