[0037] To better understand the technical solutions and beneficial effects of the present application, the present application will be further described in detail below with specific embodiments:

[0038] Please refer to Figures 1 to 5 , which is a multi-angle rotating fan 10 according to an embodiment of the present invention, including a fan blade protective cover 100, fan blades 130, a rotating part 240, a frame 200, a first driving assembly 300, a second driving assembly 400, a third driving assembly 500 and a control box 600. The fan blade protective cover 100 includes a front cover 110 and a cover body 120, and the fan blades 130 are installed in the cover body 120.

[0039] The first driving component 300 is disposed on the cover 120, and the output end of the first driving component 300 is connected to the fan blade 130. The frame 200 includes a base 230, a support column 220, a control box 600 and a support frame 210. The base 230 is connected to the bottom of the support column 220, the control box 600 is connected to the top of the support column 220, the rotating part 240 is connected below the support frame 220, and the control box 600 is located below the rotating part 240 and is rotatably connected to the rotating part 240. The second driving component 400 is located at the top of the support column 220, and the output end of the second driving component 400 is connected to the rotating part 240 to drive the rotating part 240 to rotate relative to the control box 600. Further, the number of the third driving components 500 is two, and the two third driving components 500 are respectively located at both ends of the support frame 210. Connecting parts 121 are formed on both sides of the cover 120, and the output ends of the two third driving components 500 are connected to the corresponding connecting parts 121. The control box 600 is electrically connected to the control ends of the first driving component 300, the second driving component 400 and the third driving component 500 respectively.

[0040] In this embodiment, by connecting the support frame 210 with the fan guard 100, the fan guard 100 can rotate up and down; by controlling the third driving component 500 in the connecting part 121 of the support frame 210, the fan guard 100 rotates up and down to realize the up and down air-sweeping function; by using the connection between the rotating part 240 and the support frame 210, the support frame 210 can rotate a full circle; by controlling the second driving component 400, the support frame 210 rotates left and right, so that the fan guard 100 rotates left and right to realize the left and right air-sweeping; the second driving component 400 and the third driving component 500 do not interfere with each other, and the movement of the rotating part 240 and the movement of the connecting part 121 do not interfere with each other. In this way, the multi-angle rotating fan 10 can synchronously perform left and right head shaking and up and down head swinging.

[0041] As Figure 1 and Figure 4 shown, in one embodiment, the rotating part 240 includes a hollow shaft slip ring 800. One end of the hollow shaft slip ring 800 is rotatably connected to the control box 600, and the other end of the hollow shaft slip ring 800 is connected to the support frame 210. It can be understood that the power of the second driving component 400 is transmitted to the support frame 210 by using the hollow shaft slip ring 800, so as to drive the support frame 210 to rotate, realizing the wireless connection between the second driving component 400 and the support frame 210. In this way, it can avoid the interference of the power cord and the control line when the support frame 210 rotates, so as to realize the 360° rotation of the support frame 210, and can flexibly adjust the angle and position of the fan. Further, the power cord and the control line do not need to be twisted or stretched with the rotation of the fan, avoiding the problems of damage or breakage of the wires in long-term use, thereby prolonging the service life.

[0042] As Figure 4 shown, in one embodiment, the support frame 210 is formed with a receiving cavity (not shown in the figure), the receiving cavity is communicated with the wire inlet channel of the connecting portion 121, the rotating portion 240 further includes a flange (not shown in the figure), the flange is located at the bottom of the receiving cavity, and the hollow shaft slip ring 800 is connected to the support frame 210 through the flange. It can be understood that the wires and connecting wires of the third driving assembly 500 and the first driving assembly 300 are located in the receiving cavity and are connected to the control box 600 through the hollow shaft slip ring 800. The flange rotates with the support frame 210, so that it can further avoid the interference of the power cord and the control wire when the fan guard 100 rotates, thereby realizing the 120° up and down rotation of the fan guard 100, and being able to flexibly adjust the angle and position of the fan.

[0043] As Figure 4 shown, in one embodiment, the second driving assembly 400 includes a driving motor 410, a worm (not shown in the figure) and a worm gear 420. The driving motor 410 is installed in the control box 600, the worm is rotatably arranged in the control box, one end of the worm is fixed on the driving shaft of the driving motor 410, the worm gear 420 is sleeved on one end of the hollow shaft slip ring 800, and the worm gear 420 is in meshing transmission with the worm. It can be understood that the worm and worm gear transmission has the characteristics of smoothness and silence, and there is no obvious impact and vibration during the transmission process, achieving the silent effect of the multi-angle rotating fan 10. Further, the worm and worm gear can be vertically arranged, so that the occupied space of the second driving assembly 400 is relatively small, which is convenient for installation in the control box 600. Furthermore, the worm transmission has a self-locking performance. When the second driving member 400 stops, the support frame 210 can maintain its position, such as realizing the function of arbitrarily fixing the angle when the multi-angle rotating fan 10 shakes its head left and right.

[0044] As Figure 3 shown, in one embodiment, a rotating shaft 123 is provided in each of the two connecting portions 121, and the output ends of the two third driving assemblies 500 are respectively connected to the corresponding rotating shafts 123. Specifically, in this embodiment, the two third driving assemblies 500 are synchronous motors, and the two synchronous motors rotate at a fixed speed and are connected to the fan guard 100 through the rotating shafts 123, so that the fan guard 100 rotates according to the speed and direction of the synchronous motors, avoiding vibration or noise problems caused by the non-matching of the left and right motors due to speed differences.

[0045] Furthermore, the rotating shaft 123 also plays a role in supporting and positioning the fan guard 100. As an intermediate component for connection, it can ensure that each component maintains a stable position and direction during operation.

[0046] As Figure 2 、 Figure 3 and Figure 5As shown, in one embodiment, the rotating shaft 123 is formed with a fixing bump 1231; fixing holes 1211 are formed in both connecting portions 121, and the fixing bump 1231 is located within the fixing holes 1211. It can be understood that the cooperation between the fixing bump 1231 and the fixing holes 1211 can ensure that the rotating shaft 123 is in an accurate position within the connecting portion 121, enabling a firm connection between the rotating shaft 123 and the connecting portion 121 and preventing deviation or wobbling during rotation. At the same time, it can increase the torque and force transmission ability of the rotating shaft 123 within the connecting portion 121.

[0047] Furthermore, through simple insertion and fixing operations, the rotating shaft 123 can be quickly installed onto the connecting portion 121, facilitating replacement or maintenance.

[0048] As Figure 2 and Figure 3 shown, in one embodiment, the housing 120 is formed with a motor mounting groove 1204, and the first drive assembly 300 is installed within the motor mounting groove 1204. Specifically, in this embodiment, the motor mounting groove 1204 is located inside the fan blade protection cover 100. Utilizing the structural space of the fan blade protection cover 100 itself, no additional installation support structure is required, ensuring that the first drive assembly 300 is firmly installed and simplifying the assembly process to improve efficiency.

[0049] Furthermore, in one embodiment, the first drive assembly 300 is a brushless motor, which has the characteristics of low energy consumption, low noise, and low electromagnetic interference. Using the brushless motor as the first drive assembly 300 to drive the fan blade enables the multi-angle rotating fan 10 to have stronger speed adjustability, meeting the usage requirements of high and low speeds.

[0050] As Figure 2 and Figure 3 shown, in one embodiment, the housing 120 is provided with a wire groove 1202, and the wire groove 1202 is respectively connected to the motor mounting groove 1204 and the connecting portion 121. A wire passing hole 1201 communicating with the wire groove 1202 is formed on the side surface of the housing 120, and the wire groove 1202 extends from within the motor mounting groove 1204 to the outside of the housing 120. It can be understood that the wire groove 1202 provides a safe passage, avoiding the direct exposure of wires to the external environment; at the same time, the wire groove 1202 extends to the outside of the fan blade protection cover 100, facilitating the entry or exit of wires or connecting lines through the wire passing hole 1201, simplifying the assembly process and facilitating maintenance.

[0051] As Figure 3As shown, in one embodiment, a wire groove cover 122 is provided in a wire groove 1202 on the outer side of the fan blade protection cover 100. An assembly bump 1221 is formed at one end of the wire groove cover 122; an assembly groove 1232 is formed in the rotating shaft 123, and the assembly bump 1221 is disposed in the assembly groove 1232. It can be understood that by disassembling the wire groove cover 122, the circuit can be directly inspected and assembly is facilitated; further, through the cooperation between the assembly bump 1221 on the wire groove cover 122 and the assembly groove 1232 on the rotating shaft 123, the assembly structure between the wire groove cover 122, the wire groove 1202 and the rotating shaft 123 is firm, avoiding looseness during operation.

[0052] As Figure 1 shown, in one embodiment, the support frame 210 is located outside the housing 120, and there is a rotational gap between the support frame 210 and the housing 120. It can be understood that the support frame 210 is located outside the housing, suspending the fan blade protection cover 100 to ensure that the fan blade protection cover 100 has sufficient space to rotate, and at the same time keeping a distance from the support frame 210 to avoid friction between the fan blade protection cover 100 and the support frame 210.

[0053] As Figure 1 shown, in one embodiment, the support column 220 includes an adjustment column 2201, an adjustment lock sleeve 2202 and a fixed column 2203. One end of the adjustment lock sleeve 2202 is connected to the fixed column 2203, and the adjustment column 2201 passes through the adjustment lock sleeve 2202 and is sleeved on the fixed column 2203. Specifically, in this embodiment, the adjustment lock sleeve 2202 is a threaded joint. Unscrew the adjustment lock sleeve 2202, then stretch or contract the adjustment column 2201, and tighten the adjustment lock sleeve 2202 after reaching the required length to fix it. In this way, the height adjustment function of the multi-angle rotating fan 10 can be realized. The multi-angle rotating fan 10 can thus adapt to different usage scenarios and requirements; at the same time, the threaded connection can provide a reliable locking mechanism, ensuring that the support column 220 can be firmly fixed at the selected height or position after adjustment, avoiding instability or safety hazards caused by looseness during use.

[0054] As Figure 3 shown, in one embodiment, the multi-angle rotating fan 10 further includes a negative ion generator 700. The housing 120 is provided with a placement cavity 1206 communicating with the wire groove 1202; the negative ion generator 700 is installed in the placement cavity 1206. It can be understood that the negative ion generator 700 generates negative ions and releases them into the surrounding air. The negative ions adsorb microparticles in the air, such as dust, pollen, etc., causing them to settle on the ground or nearby objects. In this way, the dust and other pollutants in the air are reduced, thereby improving the air quality.

[0055] As Figure 1As shown, in one of the embodiments, the control box 600 further includes an intelligent control component, a tracking component, a button, and a display component. The tracking component and the display component are electrically connected to the intelligent control component. The control ends of the first driving component 300, the second driving component 400, and the third driving component 500 are all electrically connected to the intelligent control component. It can be understood that the tracking component can automatically track moving objects and perform functions of human figure recognition. Therefore, the multi-angle rotating fan 10 can track and follow the rotation of the target and adjust the wind direction. The operation panel combining the display component and the touch button makes the operation more convenient.

[0056] It should be noted that this application only protects the electrical connection relationship between the control component and each component. As for the control method of the control component, it belongs to the prior art and is not within the protection scope of this application.

[0057] Compared with the prior art, this application has at least the following advantages:

[0058] By using the connection between the support frame and the fan blade protection cover, the fan blade protection cover can rotate up and down; by controlling the third driving component in the connection part of the support frame, the fan blade protection cover rotates up and down to realize the function of up and down air sweeping; by using the connection between the rotating part and the support frame, the support frame can rotate a full circle; by controlling the second driving component, the support frame rotates left and right, so that the fan blade protection cover rotates left and right to realize left and right air sweeping; the second driving component and the third driving component do not interfere with each other, and the movement of the rotating part and the movement of the connection part do not interfere with each other. In this way, the multi-angle rotating fan can perform left and right shaking and up and down shaking synchronously.

[0059] The above-described embodiments only represent several implementation manners of this application. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the disclosed patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of this application, several deformations and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the protection scope of the patent of this application should be subject to the appended claims.
