However, the lock nut is mostly assembled in the threaded connection mode with the shaft, and usually needs to be screwed in the opposite direction of the fan blade rotation to connect the shaft, resulting in a more complex assembly mode of the air outlet assembly, and the lock nut needs to be manufactured separately, so that the production and assembly process of the air outlet assembly is less convenient, and the practicability of the air outlet assembly is reduced. In view of the above problems, the utility model provides an air outlet assembly 100.

[0038] Please refer to Figures 1 to 4 In an embodiment of the utility model, the air outlet assembly 100 includes fan 10 and fan blade 30, fan 10 is equipped with shaft 11;Fan blade 30 includes rotating body 31 and connecting body 33, the circumferential side of rotating body 31 is connected with several blades 35, connecting body 33 is connected to the side of rotating body 31 towards fan 10, and is arranged along the axial direction of shaft 11;Rotating body 31 and / or connecting body and shaft 11 are magnetically attracted and matched to connect.

[0039] In the application, the blowing device can include but not limited to floor fan, table fan, heat dissipation fan, etc., the driving motor of air outlet assembly 100 drives fan blade 30 to rotate, which can form air outlet airflow with certain flow rate and flow under the rotating disturbance of fan blade 30, to realize the stable blowing operation of blowing device.

[0040] Fan blade 30 can include rotating body 31 and connecting body 33, by setting several blades 35 around the circumferential side of rotating body 31, the air flow can be disturbed when several blades 35 rotate with rotating body 31 to realize the stable air outlet of air outlet assembly 100 when rotating and driving fan blade 30 to rotate synchronously;The number of blades 35 of fan blade 30 can be set according to the blowing power required to be realized by air outlet assembly 100, and the number of blades 35 of fan blade 30 is not limited in the application.

[0041] And by setting the rotating body 31 extending along the axis direction of the rotating shaft 11 on the side of the rotating body 31 facing the fan 10, the rotating shaft 11 can be stably connected to drive the fan blade 30 to rotate by matching the connecting body 33 with the rotating shaft 11. At this time, the connecting body 33 can be provided with a mounting hole 331 corresponding to the size of the rotating shaft 11, so that the rotating shaft 11 can be inserted on the connecting body 33; or the end face of the rotating shaft 11 can be provided with a plug hole structure, so that the connecting body 33 can be inserted on the rotating shaft 11. At this time, the circumferential side of the rotating shaft 11 and one end of the connecting body 33 can be provided with mutually matched clamping structures to realize clamping limiting; or the part of the structure of the rotating shaft 11 and the mounting hole 331 of the connecting body 33 can form a pin shaft and pin hole structure to realize clamping limiting; or the circumferential side of the rotating shaft 11 and the connecting body 33 can be magnetically connected; further, the connecting body 33 and the rotating shaft 11 can have a certain mutual abutting force in the rotating direction, so that the fan 10 can drive the rotating shaft 11 to rotate, and the fan blade 30 can be stably driven by the rotating shaft 11.

[0042] By using the rotating body 31 and the rotating shaft 11 to magnetically attract and connect, the end of the rotating shaft 11 opposite to the fan 10 can be magnetically attracted to the rotating body 31. At this time, the rotating shaft 11 can be made of a magnetically attractable metal, and the rotating body 31 can be provided with a magnet or other magnetic structure corresponding to the part of the rotating shaft 11; or the rotating body 31 as a whole or the part of the structure corresponding to the rotating shaft 11 can be made of a magnetically attractable metal, and the end of the rotating shaft 11 can be provided with a magnet or other magnetic structure; or the rotating body 31 and the end of the rotating shaft 11 can be provided with magnetically opposite magnets or other magnetic structures respectively. Further, the rotating body 31 and the end of the rotating shaft 11 can be magnetically attracted and matched to realize the limiting assembly of the fan blade 30 along the axis direction of the rotating shaft 11, effectively prevent the fan blade 30 from being separated from the rotating shaft 11 along the axis direction of the rotating shaft 11, realize the stable assembly of the air outlet assembly 100, and guarantee the overall structural stability and reliability of the air outlet assembly 100.

[0043] Further, the fan blade 30 can be provided with a magnetic member having a certain magnetism on the connecting body 33, and the part of the shaft segment of the rotating shaft 11 connected with the connecting body 33 or the whole rotating shaft 11 is made of a metal material that can be magnetically attracted, so that the connecting body 33 is arranged in cooperation with the rotating shaft 11 by magnetic attraction; or the part of the shaft segment of the rotating shaft 11 connected with the connecting body 33 is provided with a magnetic member having a certain magnetism, and the connecting body 33 is made of a metal material that can be magnetically attracted, or a metal block structure that can be magnetically attracted is installed at the position corresponding to the magnetic member of the connecting body 33, so that the connecting body 33 is arranged in cooperation with the rotating shaft 11 by magnetic attraction; or the shaft segment of the rotating shaft 11 connected with the connecting body 33 is provided with two magnetic members with opposite magnetism, so that the connecting body 33 is arranged in cooperation with the rotating shaft 11 by magnetic attraction. Further, the connection stability and reliability of the connecting body 33 and the rotating shaft 11 can be further improved under the action of magnetic attraction, the fan blade 30 is limited and assembled along the axial direction on the rotating shaft 11, and the rotating shaft 11 can drive the fan blade 30 to rotate synchronously more stably, so as to further improve the structural stability and reliability of the air outlet assembly 100.

[0044] In the existing blowing device, the fan blade is locked and fixed on the rotating shaft of the motor by using a lock nut. Since there is a gap between the fan blade and the rotating shaft, the fan blade is tightly fixed on the rotating shaft of the motor by using the lock nut, which is not only complicated to operate, but also easily causes eccentric connection between the fan blade and the rotating shaft of the motor, which causes the fan blade to rotate unbalancedly and easily increases the whole machine shaking range of the blowing device. The application changes the connection mode of the fan blade 30 and the rotating shaft 11, so that the fan blade 30 and the rotating shaft 11 are magnetically attracted and connected, and the fan blade 30 can be automatically locked on the rotating shaft 11 by using the magnetic attraction force when the fan blade 30 reaches the installation position, which is convenient for installation. Meanwhile, the magnetic attraction connection between the rotating body 31 and / or the connecting body 33 and the rotating shaft 11 can only limit the position of the fan blade 30 along the axial direction, and the fan blade 30 can be kept centered with the rotating shaft 11 under the action of centrifugal force during the rotation of the fan blade 30, so that the fan blade 30 can rotate concentrically with the rotating shaft 11, effectively reduces the shaking caused by eccentric operation of the fan blade 30, and realizes more stable air outlet operation of the blowing device.

[0045] Therefore, the technical scheme of the utility model discloses that the fan blade 30 is connected with the rotating shaft 11 by the connecting main body 33, so that the rotating shaft 11 can stably drive the fan blade 30 to rotate synchronously when the rotating shaft 11 rotates, and the rotating main body 31 and / or the connecting main body 33 are magnetically attracted to the rotating shaft 11, so that the axial position of the fan blade 30 on the rotating shaft 11 can be limited by the magnetic attraction force between the rotating main body 31 and / or the connecting main body 33 and the rotating shaft 11, the fan blade 30 is effectively prevented from being separated from the rotating shaft 11, and the stable blowing operation of the air outlet assembly 100 is ensured. By using the magnetic attraction connection mode, the fan blade 30 can be directly plugged and unplugged on the rotating shaft 11, and the fan blade 30 can be automatically locked with the rotating shaft 11 when the fan blade 30 is placed in the installation position, so that the assembly process of the air outlet assembly 100 can be effectively simplified. Meanwhile, the position of the fan blade 30 in the axial direction is limited by the magnetic attraction mode, so that the fan blade 30 can be automatically centered under the action of the centrifugal force during rotation, so that the fan blade 30 and the rotating shaft 11 can have good concentricity, and the operation of the fan blade 30 is more balanced.

[0046] Referring to Figure 2 、 Figure 4 、 Figure 5 and Figure 6 In an embodiment of the utility model, the rotating main body 31 is provided with a first magnetic part 311, and the first magnetic part 311 is magnetically attracted and connected with the end of the rotating shaft 11.

[0047] In the embodiment, the fan blade 30 can be provided with the first magnetic part 311 on the rotating main body 31, and the first magnetic part 311 can be a magnet or the like structure with certain magnetism. At this time, the rotating shaft 11 can be made of a metal material that can be magnetically attracted, or the end of the rotating shaft 11 can be connected and installed with a second magnetic part 111 that is magnetically opposite to the first magnetic part 311. Then, the first magnetic part 311 can be magnetically attracted and connected with the end of the rotating shaft 11 when the rotating shaft 11 is installed with the rotating main body 31, so that the fan blade 30 can be effectively prevented from being separated from the rotating shaft 11 in the axial direction of the rotating shaft 11 under the action of magnetic attraction, the fan 10 and the fan blade 30 can be more stably assembled, and the structural stability and reliability of the air outlet assembly 100 are further improved.

[0048] The first magnetic part 311 can be fixed on the surface of the rotating main body 31 by using adhesive, or the first magnetic part 311 can be fastened and installed on the surface of the rotating main body 31 by using fasteners such as screws. Alternatively, when the rotating main body 31 is made of plastic material, the first magnetic part 311 and the rotating main body 31 can be manufactured by using an integral injection molding process, so as to ensure the stable connection between the first magnetic part 311 and the rotating main body 31. Of course, there are many ways to assemble the first magnetic part 311 and the rotating main body 31, which are not limited in the application, as long as the first magnetic part 311 can be stably arranged on the rotating main body 31.

[0049] Referring to Figure 2 , Figure 4 and Figure 7 In an embodiment of the present application, the first magnetic member 311 is arranged on the air outlet side of the rotating body 31, and the projection of the rotating shaft 11 on the rotating body 31 in the axial direction overlaps at least part of the first magnetic member 311.

[0050] In the embodiment, the first magnetic member 311 can be arranged on the air outlet side of the rotating body 31, which can be the side of the rotating body 31 facing away from the fan 10. In this case, the rotating body 31 can be made of a material that can be magnetized, so that the magnetic force lines emitted by the first magnetic member 311 can stably pass through the rotating body 31 to act on the rotating shaft 11, ensuring stable magnetic attraction between the first magnetic member 311 and the rotating shaft 11. Alternatively, the rotating body 31 can be provided with a through hole, and the first magnetic member 311 can be arranged close to one end of the through hole. In this way, the rotating shaft 11 can be inserted into the through hole, ensuring stable magnetic attraction between the first magnetic member 311 and the rotating shaft 11. By arranging the first magnetic member 311 on the side of the rotating body 31 facing away from the fan 10, the magnetic attraction between the first magnetic member 311 and the rotating shaft 11 can act on the rotating body 31, so that the rotating body 31 can be better positioned and assembled on the rotating shaft 11 in the axial direction of the rotating shaft 11. At the same time, the first magnetic member 311 can be better prevented from separating from the rotating body 31 under the action of magnetic force, ensuring more stable axial positioning and assembly of the fan blade 30 on the rotating shaft 11, and further improving the structural stability and reliability of the air outlet assembly 100.

[0051] Referring to Figure 4 and Figure 6 In an embodiment of the present application, the air outlet side of the rotating body 31 is provided with a receiving groove 313, and the first magnetic member 311 is arranged in the receiving groove 313.

[0052] In the embodiment, the rotating body 31 can be provided with a receiving groove 313 on the air outlet side. The receiving groove 313 can be arranged at the central region of the rotating body 31, so that the projection of the rotating shaft 11 on the rotating body 31 in the axial direction can overlap at least part of the receiving groove 313. By arranging the first magnetic member 311 in the receiving groove 313, the first magnetic member 311 can be stably magnetically attracted to the end of the rotating shaft 11, and the first magnetic member 311 can be limited by the receiving groove 313 to prevent the first magnetic member 311 from relatively deviating from the rotating body 31 during operation of the air outlet assembly 100. In this way, the first magnetic member 311 and the rotating body 31 can be better concentrically assembled, avoiding the possibility of eccentric installation of the first magnetic member 311 on the rotating body 31, which can cause the fan blade 30 to vibrate and generate noise. This further improves the structural stability and reliability of the air outlet assembly 100.

[0053] The first magnetic member 311 can be installed in interference fit with the inner wall of the accommodating groove 313, so that the first magnetic member 311 can be stably assembled by the outer wall and the inner clamping fit of the accommodating groove 313; or the first magnetic member 311 and the inner wall of the accommodating groove 313 can be bonded by adhesive, so as to stably install the first magnetic member 311 and the rotating main body 31.

[0054] Referring to Figures 5 to 8 In an embodiment of the present application, the fan blade 30 further comprises a cover plate 37, the cover plate 37 is connected to the air outlet side of the rotating main body 31 and abuts against the first magnetic member 311.

[0055] In the embodiment, by arranging the cover plate 37 on the air outlet side of the rotating main body 31, the installation position of the cover plate 37 corresponding to the first magnetic member 311 is arranged, and the cover plate 37 is fastened and connected with the rotating main body 31, so that the first magnetic member 311 is abutted and limited on one side of the rotating main body 31 by the cover plate 37, which is beneficial to better avoid the first magnetic member 311 from being separated from the rotating main body 31, and further improve the overall structural stability and reliability of the fan blade 30.

[0056] It can be understood that the rotating main body 31 can be provided with the accommodating groove 313 to accommodate and install the first magnetic member 311 on the side facing away from the fan 10, at this time the cover plate 37 can be attached to the surface of the rotating main body 31 facing away from the fan 10 to limit the first magnetic member 311; or the first magnetic member 311 can be abutted on the side of the rotating main body 31 facing away from the fan 10, at this time a groove corresponding in size to the first magnetic member 311 can be arranged on the cover plate 37, so that the first magnetic member 311 can be accommodated in the groove of the cover plate 37, and the cover plate 37 and the rotating main body 31 are connected in cooperation to limit the first magnetic member 311.

[0057] It should be noted that there are many ways to connect the cover plate 37 and the rotating main body 31, which are not limited in the present application; for example, a fastening structure such as a bolt or a plug can be used to pass through the cover plate 37 and be connected to the rotating main body 31 to lock the cover plate 37; or an inner thread and an outer thread structure can be arranged between the cover plate 37 and the rotating main body 31 to cooperate with each other, so that the cover plate 37 and the rotating main body 31 are connected in cooperation by screwing.

[0058] For example, referring to Figure 6 and Figure 8 In an embodiment of the present application, the air outlet side of the rotating main body 31 is provided with a connecting hole 315, the cover plate 37 is provided with a buckle member 371, the buckle member 371 is inserted into the connecting hole 315 and clamped to the rotating main body 31.

[0059] In the embodiment, the buckle 371 can be a spring structure extending outward from the side of the cover plate 37 towards the rotating body 31, and a protrusion is arranged on the outside of the spring structure, so that the buckle 371 has a certain elastic force, and then the cover plate 37 can be inserted into the connecting hole 315 of the rotating body 31, and the abutment of the buckle 371 and the rotating body 31 can make the cover plate 37 stably installed on the rotating body 31. At this time, the buckle 371 can abut against the inner wall of the connecting hole 315 by the protrusion, and the elastic force of the spring can keep the abutment of the buckle 371 and the inner wall of the connecting hole 315, so as to ensure the stable installation of the cover plate 37 on the rotating body 31. Alternatively, an opening can be arranged on the inner wall of the connecting hole 315, so that when the buckle 371 is inserted into the connecting hole 315, the protrusion can be clamped into the opening in the inner wall of the connecting hole 315, so that the cover plate 37 can be clamped and fixed on the rotating body 31, and the stable installation of the cover plate 37 on the rotating body 31 is ensured.

[0060] Referring to Figure 2 In an embodiment of the utility model, the cross-sectional area of the first magnetic part 311 is larger than that of the rotating shaft 11.

[0061] In the embodiment, by setting the cross-sectional area of the first magnetic part 311 to be larger than that of the rotating shaft 11, the first magnetic part 311 can be more stably connected to the rotating shaft 11 by magnetic attraction, so as to ensure the stable axial positioning of the fan blade 30 on the rotating shaft 11. Meanwhile, under the action of the first magnetic part 311 with a larger size, when the rotating shaft 11 passes through the rotating body 31 and contacts the first magnetic part 311 by magnetic attraction, the first magnetic part 311 can be better kept in abutment with the rotating body 31, so as to avoid the first magnetic part 311 from being separated from the rotating body 31 due to excessive magnetic attraction with the rotating shaft 11, and the part of the first magnetic part 311 contacting the rotating shaft 11 can be abutted on the surface of the rotating body 31 facing away from the connecting body 33, so as to realize the more stable axial positioning of the fan blade 30 on the rotating shaft 11, and further improve the structural reliability and practicability of the air outlet assembly 100.

[0062] In some embodiments, the first magnetic member 311 can be mounted on the surface of the rotating body 31 facing the fan 10, and the projection of the connecting body 33 on the rotating body 31 in the axial direction of the rotating shaft 11 can overlap at least part of the first magnetic member 311, so that the first magnetic member 311 can be better arranged opposite to the end of the rotating shaft 11, so that the first magnetic member 311 can be more stably magnetically attracted to the end of the rotating shaft 11, thereby ensuring the stable assembly of the fan blade 30 and the rotating shaft 11. The first magnetic member 311 can be fixed on the surface of the rotating body 31 by adhesive bonding, or can be fastened and mounted on the rotating body 31 by using bolts or screws and the like; or when the rotating body 31 is made of plastic material, the first magnetic member 311 can be integrally injection molded with the rotating body 31; so that the first magnetic member 311 is more stably assembled on the rotating body 31, avoiding the first magnetic member 311 from being separated from the rotating body 31, ensuring the stable positioning of the first magnetic member 311 on the rotating body 31 in the axial direction of the rotating shaft 11, and further improving the structural stability and reliability of the air outlet assembly 100.
