[0002] With increasing attention being paid to air quality issues, air purification equipment has become a common appliance in homes and offices.

[0003] Currently, most existing air purifiers and fans are separate, while some are combined. However, such combined air purifiers and fans require two large motors, one for exhausting air and the other for blowing air. These products consume a lot of electricity, and the noise from two motors working simultaneously is also quite loud. Therefore, we need to redesign a new technical solution based on the problems existing in the current technology to solve the problems of low power consumption and low noise. Utility Model Content

[0004] The purpose of this invention is to overcome the aforementioned deficiencies of the prior art and provide a multi-directional rotating fan for gas purification. By setting a linkage component as a structural hub and configuring left-right rotation and up-down swing mechanisms respectively, the air outlet oscillator achieves dual-degree-of-freedom movement in both the horizontal and vertical directions, thereby expanding the air delivery range, eliminating dead zones in indoor air circulation, and improving air circulation efficiency and purification uniformity. Simultaneously, by optimizing the longitudinal integrated layout of the purification body and the air delivery structure, a short airflow path and good sealing are ensured, improving overall performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A multi-directional rotating fan for gas purification includes a purification body, a linkage component, and an air outlet swing head. An air inlet / outlet drive source is provided between the interior of the purification body and the lower part of the linkage component. A left-right rotation mechanism is provided between the purification body and the linkage component, enabling the purification body and the linkage component to rotate left and right.

[0006] Furthermore, the purification body includes a base, an air inlet cover, a filter element, a fan blade mounting housing, and an air inlet / outlet drive source; the air inlet cover and the filter element are disposed on the base, the filter element is disposed inside the air inlet cover, the fan blade mounting housing is disposed on the top of the air inlet cover, and the air inlet / outlet drive source includes a fan blade and a fan blade drive motor, the fan blade is rotatably connected to the lower part of the fan blade mounting housing, and the fan blade drive motor is fixedly disposed on the fan blade mounting housing and connected to the fan blade drive.

[0007] Furthermore, the top surface of the air inlet cover is provided with a positioning assembly groove, which is adapted to the outer contour of the fan blade mounting housing, and the fan blade mounting housing is disposed in the positioning assembly groove and assembled with the air inlet cover.

[0008] Furthermore, the top surface of the fan blade mounting housing is provided with a limiting assembly groove, which is adapted to the bottom outer contour of the linkage component, and the middle part of the fan blade mounting housing is provided with an upwardly extending bushing.

[0009] Furthermore, the linkage component has a shaft hole at the top and an open structure at the bottom, which is connected to the shaft hole.

[0010] Furthermore, the air outlet swing head is provided with a clearance groove, which is used for the upper part of the linkage to be connected. The inner side of the clearance groove is provided with an outwardly protruding convex shaft structure. The outer diameter of the convex shaft structure is adapted to the inner diameter of the shaft hole on the linkage.

[0011] Furthermore, the air outlet swing head is provided with an air outlet grille cover, and the front side of the air outlet grille cover is provided with an operation panel and a circuit board built into the cavity of the air outlet grille cover.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 10 As shown, this embodiment provides a technical solution: a multi-directional rotating fan for gas purification, including a purification body 1, a linkage 2, and an exhaust oscillator 3. An air inlet / outlet drive source is disposed between the interior of the purification body 1 and the lower part of the linkage 2. A left-right rotation mechanism 4 is disposed between the purification body 1 and the linkage 2, enabling left-right rotation. A right-right swing mechanism 5 is disposed between the exhaust oscillator 3 and the linkage 2, enabling up-down swing. By distributing the air inlet / outlet drive source between the interior of the purification body 1 and the lower part of the linkage 2, the generated airflow is directly positioned between the outlet of the purification duct and the inlet of the moving mechanism. This arrangement ensures that the airflow generated by the drive source must be filtered inside the purification body 1 before being discharged, achieving a true circulating purification fan. Simultaneously, it allows the airflow to enter the exhaust oscillator 3 smoothly and be discharged to the external environment with the shortest path and minimal loss. This significantly optimizes the overall structural compactness and airflow efficiency. By setting the linkage 2 as the structural hub and configuring the left-right rotation mechanism 4 and the up-down swing mechanism 5 respectively, the air outlet oscillator 3 achieves two degrees of freedom of movement in the horizontal and vertical directions. This allows the purified airflow to cover a wider area of ​​space, effectively eliminating dead zones in indoor air circulation and significantly improving the air circulation efficiency and purification uniformity of the entire room.

[0022] It should be noted that the design of this patent uses an air-driving motor to achieve both air intake and air delivery to the oscillating air outlet. This design is excellent in terms of energy saving and quiet operation.

[0023] The purification unit 1 includes a base 11, an air inlet cover 12, a filter element 13, a fan blade mounting housing 14, and an air intake / exhaust drive source. The air inlet cover 12 and the filter element 13 are mounted on the base 11, with the filter element 13 located inside the air inlet cover 12. The fan blade mounting housing 14 is located on top of the air inlet cover 12. The air intake / exhaust drive source includes fan blades 15 and a fan blade drive motor 16. The fan blades 15 are rotatably connected to the lower part of the fan blade mounting housing 14, and the fan blade drive motor 16 is fixedly mounted on the fan blade mounting housing 14 and driven by the fan blades 15. By placing the filter element 13 inside the air inlet cover 12 and the fan blades 15 on top of it, a compact and efficient vertically integrated structure is formed, purifying the air before supplying it. This layout ensures that all drawn-in air must be purified by the filter element, avoiding leakage of unpurified air, while also ensuring a short and smooth airflow path, reducing air pressure loss, and improving overall performance. This forms a highly integrated "power-air duct" module: the fan blade drive motor 16 directly drives the fan blades 15, drawing the air purified by the filter element 13 upwards and directly sending it into the cavity of the upper linkage 2. The direct power transmission and minimal energy loss enable the entire device to operate efficiently.

[0024] The top surface of the air inlet cover 12 is provided with a positioning assembly groove 121, which is adapted to the outer contour of the fan blade mounting housing 14. The fan blade mounting housing 14 is set in the positioning assembly groove 121 and assembled with the air inlet cover 12. Through the matching assembly of the positioning assembly groove 121 and the outer contour of the fan blade mounting housing 14, precise positioning and stable connection between the two are achieved. This structure effectively prevents loosening and abnormal noise during operation, improves the structural rigidity and reliability of the product, and ensures the sealed connection between the lower purification air duct and the upper air supply air duct.

[0025] The top surface of the fan blade mounting housing 14 is provided with a limiting assembly groove 141, which is adapted to the bottom outer contour of the linkage 2. A bushing 142 extending upwards is provided in the middle of the fan blade mounting housing 14. The limiting assembly groove 141 ensures a stable assembly between the linkage 2 and the fan blade mounting housing 14, providing a reliable connection point for left and right rotation. The bushing 142 in the middle provides a robust mounting position for the rotating driven member 43, ensuring effective transmission of gear power and stable support for the entire rotating component.

[0026] The linkage 2 has a shaft hole 21 at its upper part and an open structure 22 at its bottom, which is connected to the shaft hole 21. The open structure 22 at the bottom of the linkage 2 provides a large-area, low-resistance air intake channel, allowing airflow from the purification unit below to enter smoothly. This channel, together with the shaft hole 21 at the top, forms a highly efficient airflow channel that runs through the interior of the linkage, minimizing eddies and pressure loss.

[0027] The air outlet oscillating head 3 is provided with a recessed groove 31 for the upper part of the linkage 2 to enter. The inner side of the recessed groove 31 has an outwardly protruding convex shaft structure 32. The outer diameter of the convex shaft structure 32 matches the inner diameter of the shaft hole 21 on the linkage 2. The convex shaft structure 32 has an opening channel 321 that communicates with the shaft hole 21. Through the cooperation between the convex shaft structure 32 and the shaft hole 21, a simple and reliable rotational connection between the air outlet oscillating head 3 and the linkage 2 is achieved. The design of the opening channel 321 ensures that even during oscillation, the airflow inside the linkage 2 can enter the air outlet oscillating head 3 without obstruction.

[0028] The air outlet oscillator 3 is equipped with an air outlet grille cover 33. The front side of the air outlet grille cover 33 is equipped with an operation panel 6 and a circuit board built into the cavity of the air outlet grille cover. The control panel 6 is integrated on the air outlet grille cover 33, allowing users to conveniently and intuitively operate and adjust various functions of the fan, such as wind speed, oscillation, and timer, greatly improving the human-computer interaction and ease of operation of the product. At the same time, this location can also efficiently dissipate heat from the control panel and circuit board.

[0029] The left and right rotating mechanism 4 includes a rotary drive motor 41, a rotary main gear 42, and a rotary driven member 43. The rotary drive motor 41 is fixedly mounted inside the linkage 2. The rotary main gear 42 is connected to the output shaft of the rotary drive motor 41. The rotary driven member 43 is fixedly mounted on a bushing 142 on the fan blade mounting housing 14. The outer side of the rotary driven member 43 has an arc-shaped gear structure that meshes with the rotary main gear 42. This gear meshing scheme, where the rotary drive motor 41 drives the rotary main gear 42 and the rotary driven member 43, provides a precise transmission ratio and smooth, reliable transmission.

[0030] The up-and-down swing mechanism 5 includes a swing drive motor 51, a swing main gear 52, and a swing follower 53. The swing drive motor 51 is fixedly installed inside the air outlet swing head 3. The swing main gear 52 is connected to the output shaft of the swing drive motor 51. The swing follower 53 is fixedly installed on the linkage 2. The swing follower 53 has an arc-shaped gear structure on its outer side, which meshes with the swing main gear 52. By using the swing drive motor 51 to drive the swing main gear 52 and the swing follower 53, the air outlet swing head 3 can achieve precise and smooth pitch swing.

[0031] The gas purification process and the working process of each functional mechanism of this utility model are as follows: Gas purification process: Under the negative pressure generated by the rotation of the fan blades 15, external air is drawn in through the air inlet of the air inlet cover 12. The air first passes through the filter element 13 located inside the air inlet cover 12, where dust, particulate matter, and other pollutants are adsorbed and filtered, completing the purification process. Driven by the upward rotation force of the fan blades 15, the purified air flows upward, passing sequentially through the internal channel of the fan blade mounting housing 14, the open structure 22 at the bottom of the linkage 2, and its internal cavity, finally entering the air outlet oscillator 3, and finally being smoothly discharged to the external environment through the air outlet grille cover 33 of the air outlet oscillator 3.

[0032] Left and right rotation process: When it is necessary to change the horizontal air supply direction, the rotary drive motor 41 fixed inside the linkage 2 is activated, and the motor drives the rotary main gear 42 on its output shaft to rotate. The rotary main gear 42 meshes with the rotary driven member 43 fixedly installed on the bushing 142 of the fan blade mounting housing 14. Since the rotary driven member 43 is fixed to the purification body 1, and the rotary drive motor 41 and the rotary main gear 42 are fixed to the linkage 2, under the reaction force of the gear meshing, the entire linkage 2 and the air outlet swing head 3 connected to it are driven to rotate in the left and right directions relative to the purification body 1, thereby realizing multi-angle air supply in the horizontal plane.

[0033] Up-and-down swing process: The up-and-down swing function is independent of the left-and-right rotation, realizing the pitch angle adjustment of the air outlet swing head 3; this function is driven by the swing drive motor 51 installed inside the air outlet swing head 3, the motor drives the swing main gear 52 to rotate, and the swing main gear 52 meshes with the swing driven member 53 fixedly installed on the linkage 2; at any moment when the left and right rotation is stationary, the linkage 2 can be used as a fixed base, at which time the gear transmission will force the air outlet swing head 3 to swing up and down relative to the linkage 2 with its convex shaft structure 32 as the fulcrum, thereby flexibly changing the vertical tilt angle of the delivered airflow.
