[0033] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.

[0034] Reference Figures 1 to 10 As shown, it shows an embodiment of the fan blade structure and fan of the present invention. The fan blade structure includes a fan blade 1 and a bracket 2. The fan blade 1 includes a root 11, and the root 11 includes a first side 111 and a second side 112 that are oppositely arranged and have different slopes. The bracket 2 is magnetically connected to the root 11. The outer wall of the bracket 2 is provided with a mounting groove 21 with a width greater than the width of the root 11. The mounting groove 21 includes a first side wall 211 and a second side wall 212 that are oppositely arranged and match the first side 111 and the second side 112 respectively. The first side wall 211 forms a first angle when abutting against the first side 111, and the second side wall 212 forms a second angle when abutting against the second side 112.

[0035] Specifically, the fan blade structure is mainly suitable for the fan field, especially in the technical field of circulation fans. The fan blade structure can freely adjust the angle of the fan blade 1 to meet different usage scenarios. Under the same fan gear, it can further reduce energy consumption by adjusting the angle of the fan blade 1, so that high air volume can be achieved at low wind speed. Furthermore, noise can be reduced by adjusting the adaptive angle of the fan blade 1.

[0036] The fan blade structure includes a fan blade 1 and a bracket 2. The fan blade 1 is used to rotate to achieve air flow. Different angles of the fan blade 1 will generate different wind volumes; the fan blade 1 includes a root 11, which is the installation position of the fan blade 1, that is, the root 11 is located on the side of the fan blade 1 facing the bracket 2 and abutting the bracket 2, and the root 11 is mainly used to connect the fan blade 1 and the bracket 2; the root 11 includes a first side 111 and a second side 112, the first side 111 and the second side 112 are arranged opposite to each other, the first side 111 and the second side 112 are both extended along the length direction of the root 11, and the slopes of the first side 111 and the second side 112 are different, so that the fan blade 1 can be installed on the bracket 2 at different angles, thereby generating different wind volumes.

[0037] The bracket 2 is used to connect the fan blades 1 and the base so that the fan blades 1 can form a fan body with the base; the bracket 2 is generally annular structure, and multiple fan blades 1 are installed on the bracket 2 at intervals and evenly along the circumference of the bracket 2, and the fan blades 1 are rotated by rotating the bracket 2 to generate wind; in this embodiment, the connection method between the bracket 2 and the fan blades 1 is magnetic connection, that is, the bracket 2 and the root 11 are connected by magnetic attraction. The magnetic connection method is simple and has high stability, and it can also make the connection between the bracket 2 and the root 11 detachable and movable, thereby facilitating users to quickly, easily and flexibly adjust the installation angles of the fan blades 1 and the bracket 2 to generate different wind volumes, thereby being suitable for a variety of usage scenarios and reducing energy consumption.

[0038] The outer wall of the bracket 2 is provided with a mounting groove 21, and the mounting groove 21 is used to install the fan blade 1. The mounting groove 21 is formed by the outer wall of the bracket 2 being recessed inward. The number of the mounting grooves 21 is set to be consistent with the number of the fan blades 1, so that the fan blades 1 can be correspondingly arranged in the mounting grooves 21; at the same time, the width of the mounting groove 21 is greater than the width of the root 11, so that when the root 11 is installed, the position of the root 11 in the width direction of the mounting groove 21 can be freely adjusted, thereby adjusting the installation angle of the fan blade 1.

[0039] The mounting groove 21 includes a first side wall 211 and a second side wall 212, and the first side wall 211 and the second side wall 212 are arranged opposite to each other, and the first side wall 211 and the second side wall 212 are respectively adapted to the first side edge 111 and the second side edge 112, that is, the shape of the first side wall 211 is the same as the shape of the first side edge 111, and the slope of the first side wall 211 is consistent with the slope of the first side edge 111, so that the first side wall 211 can be completely and tightly fitted with the first side edge 111; the shape of the second side wall 212 is the same as the shape of the second side edge 112, and the slope of the second side wall 212 is consistent with the slope of the second side edge 112, so that the second side wall 212 can be completely and tightly fitted with the second side edge 112.

[0040] Because the first side wall 211 and the second side wall 212 have different slopes, and the first side edge 111 and the second side edge 112 have different slopes, a first angle is formed when the first side wall 211 and the first side edge 111 abut against each other, and a second angle is formed when the second side wall 212 and the second side edge 112 abut against each other. The first angle and the second angle refer to different installation angles of the fan blade 1.

[0041] When the user overcomes the magnetic attraction and removes or moves the fan blade 1 to a position close to the first side wall 211 to install the fan blade 1, the fan blade 1 is installed to the bracket 2 in a form that the first side wall 211 and the first side edge 111 are completely fitted together. At this time, the fan blade 1 and the bracket 2 form the first angle, which is the inclination angle formed by the slope of the first side wall 211 and the first side edge 111; when the user overcomes the magnetic attraction and removes or moves the fan blade 1 to a position close to the second side wall 212 to install the fan blade 1, the fan blade 1 is installed to the bracket 2 in a form that the second side wall 212 and the second side edge 112 are completely fitted together. At this time, the fan blade 1 and the bracket 2 form the second angle, which is the inclination angle formed by the slope of the second side wall 212 and the second side edge 112.

[0042] Therefore, the present application connects the bracket 2 and the fan blade 1 by magnetic attraction, so that the installation angle of the fan blade 1 and the bracket 2 can be quickly adjusted, and the adjustment method is simple; and the root 11 of the fan blade 1 is provided with the first side 111 and the second side 112 with different slopes, and the bracket 2 is provided with the first side wall 211 and the second side wall 212 with the same slope as the first side 111 and the second side 112 respectively. By adjusting the first side wall 211 and the first side 111 to abut or the second side wall 212 and the second side 112 abut to achieve the installation of the fan blade 1 on the bracket 2 according to the first angle or the second angle, so that the installation angle of the fan blade 1 can be adjusted. The user can adjust the installation angle according to actual needs to adjust the air volume and air pressure, optimize the working state of the fan, and thus reduce energy consumption and improve energy efficiency; at the same time, the installation angle can be adjusted to optimize the airflow path, reduce turbulence and eddy currents, thereby reducing noise levels and improving user experience; finally, the installation angle of the fan blade 1 can also be adjusted according to the needs of different application scenarios to improve the flexibility and applicability of the system.

[0043] More specifically, refer to Figures 3 to 6 As shown, the slope of the first side 111 is greater than the slope of the second side 112; wherein, the fan blade 1 and the bracket 2 are magnetically connected along the first side wall 211 and the first side 111 in a high air volume state; and the fan blade 1 and the bracket 2 are magnetically connected along the second side wall 212 and the second side 112 in a low air volume state.

[0044] More specifically, the first side 111 is configured as an arc-shaped structure, thereby improving the fluidity of the airflow when the fan blade 1 rotates, thereby increasing the air volume.

[0045] In one embodiment, referring to Figure 1 、 Figure 3、 Figure 5 As shown, the root 11 is fixed with a first magnetic part, and the bracket 2 is fixed with a second magnetic part 22 that is magnetically connected to the first magnetic part. Specifically, the connection method of the root 11 and the bracket 2 is a magnetic connection, so that the user can adjust the installation angle of the fan blade 1 to achieve different air volumes; therefore, the root 11 is fixed with a first magnetic part, and the first magnetic part is magnetic; at the same time, the bracket 2 is fixed with a second magnetic part 22, and the second magnetic part 22 can be set on the outer wall or inner wall of the bracket 2 or in the installation groove 21, which is not limited here. The second magnetic part 22 is magnetic, and the second magnetic part 22 and the first magnetic part are magnetically connected. Therefore, the magnetic connection between the fan blade 1 and the bracket 2 can be achieved through the first magnetic part and the second magnetic part 22. The connection method is simple, and the structures of the fan blade 1 and the bracket 2 are simple, and the production cost is low.

[0046] More specifically, in this embodiment, the first magnetic member is fixedly provided on a side surface where the root 11 abuts against the bracket 2, thereby further increasing the magnetic attraction force between the first magnetic member and the second magnetic member 22 to improve the fixity of the connection between the fan blade 1 and the bracket 2.

[0047] More specifically, the first magnetic part is an iron sheet, and the second magnetic part 22 is a magnet. During the processing of the fan blade 1, the iron sheet is embedded in the root 11 of the fan blade 1 through an insert injection molding process, thereby ensuring that the iron sheet is not easy to fall off from the root 11, thereby improving the structural stability and service life of the fan blade 1.

[0048] In a specific embodiment, referring to Figure 1 As shown, the inner wall of the bracket 2 is provided with an inwardly recessed groove 23, and the groove 23 is used to install the second magnetic member 22. Specifically, the inner wall of the bracket 2 is provided with a groove 23, and the groove 23 is formed by the inner wall of the bracket 2 being recessed toward the outer wall. The groove 23 extends along the circumference of the inner wall of the bracket 2. The groove 23 is used to install the second magnetic member 22, so that the second magnetic member 22 is installed in the groove 23, so as to improve the structural stability of the bracket 2, prevent the second magnetic member 22 from falling, and protect the second magnetic member 22 from being damaged.

[0049] More specifically, the second magnetic member 22 is embedded in the groove 23 , thereby fixing the second magnetic member 22 in a simple installation manner.

[0050] In one embodiment, referring to Figure 3 、 Figure 5As shown, there are multiple grooves 23, and the multiple grooves 23 are arranged at intervals along the circumference of the inner wall of the bracket 2, and the second magnetic member 22 is fixed in each groove 23. Specifically, the grooves 23 can be arranged in the form of one or more on the inner wall of the bracket 2; when there is one groove 23, the groove 23 is extended along the circumference of the inner wall of the bracket 2, and the number of the second magnetic members 22 can be one or more. If there is one second magnetic member 22, the second magnetic member 22 can be arranged along the extension direction of the groove 23; if there are multiple second magnetic members 22, the multiple second magnetic members 22 are fixed in the groove 23 along the circumference of the groove 23.

[0051] When there are multiple grooves 23, the multiple grooves 23 are arranged at circumferential intervals along the inner wall of the bracket 2, and the second magnetic part 22 needs to be installed in each of the grooves 23, so as to ensure that the second magnetic part 22 can magnetically connect the fan blade 1 at each position along the circumference of the bracket 2, thereby improving the connection stability between the second magnetic part 22 and the first magnetic part, and improving the magnetic attraction force between the first magnetic part and the second magnetic part 22.

[0052] In a specific embodiment, the number of the grooves 23 is consistent with the number of the fan blades 1 (not shown in the figure). Specifically, the number of the grooves 23 is consistent with the number of the fan blades 1, and each of the grooves 23 is fixedly provided with a second magnetic member 22. Therefore, the number of the second magnetic members 22 is consistent with the number of the fan blades 1, that is, the number of the second magnetic members 22 is consistent with the number of the first magnetic members. This further improves the magnetic attraction between the second magnetic members 22 and the first magnetic members, further improves the installation stability of the fan blade 1 and the bracket 2, and improves the structural stability of the fan blade structure.

[0053] More specifically, the positions of the plurality of grooves 23 may not correspond to the installation positions of the fan blades 1 , thereby improving the generation efficiency.

[0054] In one embodiment, referring to Figures 1 to 8As shown, the bottom wall of the mounting slot 21 is provided with two limiting slots 213, respectively close to the first side wall 211 and the second side wall 212. The root portion 11 is also provided with a rib 113, which engages with any of the limiting slots 213. Specifically, two limiting slots 213 are provided on the bottom wall of the mounting slot 21. The limiting slots 213 are used to further connect the root portion 11 and the bracket 2, thereby improving the fixation of the fan blade 1 and the bracket 2. The limiting slots 213 are recessed from the bottom wall of the mounting slot 21 toward the inner wall of the bracket 2, and the two limiting slots 213 are respectively provided near the first side wall 211 and the second side wall 212.

[0055] The root portion 11 is further provided with a rib 113 , which protrudes from a side surface of the root portion 11 abutting against the mounting groove 21 toward the mounting groove 21 . The shape of the rib 113 matches the shape of the limiting groove 213 , and the rib 113 is snap-fitted into any one of the limiting grooves 213 .

[0056] When the root 11 is installed at the position where the first side 111 and the first side wall 211 abut each other, the rib 113 is engaged with the limiting groove 213 close to the first side wall 211; when the root 11 is installed at the position where the second side 112 and the second side wall 212 abut each other, the rib 113 is engaged with the limiting groove 213 close to the second side wall 212.

[0057] Therefore, the present application further provides two limiting grooves 213 in the installation groove 21, and further limits and fixes the installation position of the root 11 and the bracket 2 through the clamping method of the limiting grooves 213 and the rib 113, so as to avoid the unstable connection between the root 11 and the bracket 2 causing the fan blade 1 to fall; at the same time, it can also limit the installation position of each fan blade 1, improve the structural stability of the fan blade structure, and avoid the installation position of each fan blade 1 from being offset, thereby affecting the uniformity of the air volume and the aesthetics of the fan.

[0058] More specifically, the side surface of the rib 113 that abuts against the bottom wall of the limiting groove 213 is an arc-shaped structure, so that the installation angle of the fan blade 1 can be better changed.

[0059] In a specific embodiment, the outer surface of the rib 113 is provided with a magnetic material coating (not shown in the figure). Specifically, the magnetic material coating is a technology or process in which a magnetic material is attached to the outer surface of the rib 113 in the form of a film or thin layer. Since the rib 113 is a portion of the structure that protrudes outward from the root 11, the material of the rib 113 is the same as the material of the root 11, that is, the rib 113 is not magnetic; therefore, the magnetic material coating is provided on the outer surface of the rib 113, and the magnetic material coating is completely provided on the entire outer surface of the rib 113, so that the outer surface of the rib 113 is magnetic. The rib 113 and the second magnetic member 22 can generate a magnetic attraction, thereby strengthening the magnetic connection between the root 11 and the bracket 2, improving the stability and fixity of the connection between the fan blade 1 and the bracket 2, and preventing the fan blade 1 from shaking or falling.

[0060] In one embodiment, referring to Figure 2 As shown, a clamping groove 2131 is provided on the side wall of the limiting groove 213 , and a buckle 1131 protruding toward the clamping groove 2131 is provided on the side surface of the rib 113 , and the buckle 1131 is clamped with the clamping groove 2131 . Specifically, a card slot 2131 is provided in the limiting groove 213, and the card slot 2131 is arranged on the side wall of the limiting groove 213. The card slot 2131 is used to be engaged with the card buckle 1131 of the convex rib 113 to improve the fixed connection between the limiting groove 213 and the convex rib 113; the convex rib 113 is provided with a card buckle 1131, and the card buckle 1131 is arranged on the side of the convex rib 113, and the card buckle 1131 is raised in the direction of the card slot 2131. The card buckle 1131 and the card slot 2131 are arranged correspondingly. When the convex rib 113 is installed in the limiting groove 213, the card buckle 1131 will be engaged with the card slot 2131, so that the convex rib 113 is engaged in the limiting groove 213 to improve the fixing stability of the fan blade 1 and the bracket 2. When disassembling, the user needs to use greater force to overcome the clamping force of the buckle 1131 and the slot 2131 and the magnetic attraction force of the first magnetic part and the second magnetic part 22 to remove the fan blade 1 and then adjust the installation angle of the fan blade 1.

[0061] More specifically, there can be multiple card slots 2131, and the multiple card slots 2131 are arranged at intervals along the length of the limiting groove 213. The side of the rib 113 is provided with multiple clips 1131, and the multiple clips 1131 are arranged at intervals along the length of the rib 113. During installation, the multiple clips 1131 are respectively connected to the multiple card slots 2131 in a one-to-one correspondence, so as to further improve the clipping fixation of the rib 113 and the limiting groove 213, thereby improving the fixing stability of the fan blade 1 and the bracket 2.

[0062] More specifically, both side walls of the limiting groove 213 may be provided with the card slot 2131, and the corresponding two side surfaces of the rib 113 may also be provided with the card buckle 1131 to further improve the card connection and fixation between the rib 113 and the limiting groove 213, which is not limited here.

[0063] In a specific embodiment, referring to Figure 9 、 Figure 10 As shown, the buckle 1131 is provided with an elastic groove 11311, which is formed by a side of the buckle 1131 being recessed toward the end face of the root 11. Specifically, the buckle 1131 is provided with the elastic groove 11311, which is formed by a side of the buckle 1131 being recessed toward the end face of the root 11, the end face of the root 11 referring to the side of the root 11 that abuts the bottom wall of the mounting groove 21, i.e., the side on which the first magnetic member is mounted. The top end of the elastic groove 11311 is open, and the notch of the elastic groove 11311 is located on the side of the buckle 1131 that is away from the end face of the root 11. The elastic groove 11311 has sidewalls on both sides, and the elastic grooves 11311 are used to enhance the elastic force of the sidewalls of the buckle 1131.

[0064] When the root 11 is installed from the outside to the inside toward the position of the installation slot 21, the rib 113 moves toward the bottom wall of the limiting slot 213 until the buckle 1131 enters the slot 2131, and the notch of the elastic slot 11311 first enters the slot 2131. At this time, the side walls of the buckle 1131 are squeezed by the side walls of the slot 2131, and the elastic slot 11311 can make the side walls at both ends move toward the direction of the elastic slot 11311, thereby making it easier for the buckle 1131 to be snapped into the slot 2131; when the buckle 1131 is fully snapped into the slot 2131, the side walls of the buckle 1131 return to their initial position, so that the buckle 1131 is fully snapped into the slot 2131, thereby improving the snap-connection stability of the buckle 1131 and the slot 2131.

[0065] Specifically, the buckle 1131 is provided with two elastic grooves 11311, and the two elastic grooves 11311 are arranged at intervals along the length of the buckle 1131, thereby further improving the elastic force of the buckle 1131, further improving the clamping stability and fixation of the buckle 1131 and the slot 2131, and also improving the structural strength of the buckle 1131.

[0066] This embodiment also provides a fan (not shown in the figure), which includes a blade structure. The blade structure can adopt any blade structure provided by the present invention. Since the specific structure and working principle of the blade structure have been introduced in detail in the previous description, they will not be repeated here for the sake of brevity.

[0067] The fan in this embodiment adopts the fan blade structure provided by the present invention, and the angle of the fan blade 1 can be freely adjusted, so that the fan can be applied to a variety of usage scenarios. The user can adjust the angle of the fan blade 1 according to actual needs to improve the applicability of the fan; at the same time, it can also reduce the energy consumption of the fan, and high air volume can be achieved even at the low gear of the fan; finally, the fan generates low noise, which improves the user experience.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention.
