[0018] The following is a detailed description of the embodiments of the present invention. The examples of the embodiments are shown in the drawings, and the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are examples for explaining the present invention, and should not be understood as limiting the present invention.

[0019] The present invention relates to a quick-installation fan, which includes a hub 100, a plurality of blades 200, and a fixing member 300.

[0020] As shown in Figures 1, 2, 5, and 6, the hub 100 can be assembled from two half housings, and the interior of the hub 100 forms a cavity. A plurality of mounting portions 110 are provided on the hub 100, and the mounting portions 110 are opened on the circumferential side walls of the hub 100 along the circumferential direction of the hub 100, connecting the interior and exterior of the hub 100. The opening shape of the mounting portions 110 matches the end shape of the blades 200, and one blade 200 is inserted into one mounting portion 110. The fixing members 300 are attached to the hub 100 and can be attached to the cavity inside the hub 100. One fixing member 300 can be attached to each mounting portion 110, or each mounting portion 110 can share the same fixing member 300, which is an integrated unit. The fixing member 300 can move relative to the hub 100, and the movement of the fixing member 300 can be translational, rotational, swinging, etc. In this embodiment, the fixing member 300 rotates along the axial direction of the hub 100. The fixing member 300 can move relative to the hub 100 to a first position, a second position, and a third position. The fixing member 300 can move between the first and second positions using elastic force. As shown in FIG. 8, the fixing member 300 is in the second position when it is not subjected to any external force. As shown in FIG. 9, when the end of the blade 200 is inserted into the insertion portion 110, the blade 200 abuts against the fixing member 300, pushing the fixing member 300 and moving from the second position to the first position. As shown in FIG. 8, once the blade 200 is inserted into the predetermined position, the fixing member 300 loses its acting force and automatically returns from the first position to the second position. At this time, the fixing member 300 prevents the blade 200 from coming off the mounting portion 110 by engaging, shifting, or other methods, and temporarily connects the blade 200 to the hub 100. As shown in Figure 10, the fixing member 300 can be moved from the second position to the third position by manually moving the fixing member 300. When the fixing member 300 is in the third position, the fixing member 300 is fixed onto the hub 100, and the blade 200 can be tightened into the mounting portion 110, completing the installation of the blade 200.When removing or replacing the blades 200, the fixing member 300 is manually moved from the third position to the second position to release the clamped state, and then the fixing member 300 is switched from the second position to the first position to remove the blades 200 from the mounting portion 110. This allows the blades 200 to be quickly attached to and detached from the hub 100, making installation very convenient and eliminating the need for additional tools or complicated operations such as tightening screws. The fan rotates by driving the hub 100 through the motor 600. The quick-attach fan allows different hubs 100 and blades 200 to be combined and used, improving versatility and model compatibility.

[0021] In some specific embodiments of the present invention, as shown in FIGS. 5 and 6, the fixing member 300 corresponding to each of the inserts 110 is the overall structure. The fixing member 300 is annular and coaxially mounted inside the hub 100. The fixing member 300 rotates within the hub 100 along the axial direction of the hub 100. The cavity of the hub 100 may be provided with an annular groove, and the fixing member 300 slidably connects to the annular groove and rotates to guide the direction. A plurality of sockets 310 are formed on the fixing member 300, and the number of sockets 310 is the same as the number of inserts 110, and the sockets 310 correspond one-to-one to the inserts 110. The fixing member 300 rotates relative to the hub 110, and each socket 310 rotates simultaneously with the inserts 110. The fixing member 330 moves each socket 310 between a first position, a second position, and a third position. The first position, the second position, and the third position are arranged sequentially along the axial direction of the hub 100. Before installation, the receptacle 310 is on the second position. When the end of the blade 200 is inserted into the insertion portion 110, the end of the blade 200 is inserted into the receptacle 310, and the blade 200 pushes the receptacle 310, moving it from the second position to the first position. When the blade 200 is inserted to the predetermined position, the receptacle 310 automatically returns from the first position to the second position. The receptacle 310 is misaligned with the blade 200, thereby preventing the blade 200 from coming off the insertion portion 110.

[0022] 6, 7, and 9, a sloped wall 311 is provided on one side wall of the insertion hole 310. The sloped wall 311 forms a certain angle with the diameter of the fixing member 300. A pressing portion 210 is provided on the blade 200, and the pressing portion 210 can protrude from the end of the blade 200. The pressing portion 210 can be a triangular prism as shown in the figures, but it can also be in the shape of a cylinder, a boss, or the like. When installing the blade 200, the pressing portion 210 is inserted into the insertion portion 110 and then inserted into the insertion hole 310. The pressing portion 210 abuts on the sloped wall 311. The sloped wall 311 slides against the pressing portion 210, and the pressing portion 210 moves along the radial direction of the fixing member 300, pressing the fixing member 300 via the sloped wall 311, and gradually rotates along the axial direction from the second position to the first position. When pressing portion 210 continues to move until it penetrates insertion port 310, pressing portion 210 disengages from inclined wall 311, inclined wall 311 loses the acting force of pressing portion 210, and fixing member 300 returns from the first position to the second position. At this time, pressing portion 210 is on the inner ring side wall of fixing member 300 and is misaligned with insertion port 310, thereby preventing blade 200 from disengaging from insertion portion 110 via insertion port 310.

[0023] Here, a stopper 320 is provided on the fixing member 300, and the stopper 320 is positioned on the movement path of the pressing portion 210 passing through the insertion port 310, so that the pressing portion 310 can abut against the stopper 320, thereby limiting the installation depth of the blade 200 to a certain extent.

[0024] In some embodiments of the present invention, a chuck 330 is provided on the fixing member 300. In this embodiment, the chuck 330 can be provided on the stopper 320, but it can also be provided at other locations on the fixing member 300. The chuck 300 can be provided in an arc-shaped configuration. A first engagement portion 121 and a second engagement portion 122 are provided in the cavity of the hub 100. The first engagement portion 121 extends in a groove-like manner along the axial direction of the hub 100. The second engagement portion 122 has a notch-like configuration. A separation portion 123 is provided between the first engagement portion 121 and the second engagement portion 122. The separation portion 123 protrudes along the radial direction of the hub 100 and separates the first engagement portion 121 and the second engagement portion 122. When the fixing member 300 moves between the first position and the second position, the chuck 330 slides within the first engagement portion 121. When the fixing member 300 moves from the second position to the third position, the check 300 escapes from the first engaging portion 121, and the chuck 330 passes over the separating portion 123 and enters the second engaging portion 122, whereupon the check 330 engages with the second engaging portion 122. At this time, the fixing member 300 cannot rotate and move away from the third position.

[0025] In some specific embodiments of the present invention, as shown in Figures 2 and 3, the fixed member 300 is provided with a control lever 340. The control lever 340 extends radially from the circumferential side wall of the fixed member 300. A position limiting opening 130 is opened on the hub 100. The fixed member 300 is attached to the inside of the hub 100, and the control lever 340 passes through the position limiting opening 130 and protrudes from the outside of the hub 100. The control lever 340 moves simultaneously with the fixed member 300. The fixed member 300 can be moved by moving the control lever 340.

[0026] Some embodiments of the present invention further include an elastic member 400. The elastic member 400 exerts an elastic force on the fixed member 300, and this elastic force is used to move the fixed member 300 from the first position to the second position. The elastic member 400 can be a torsion spring 410, a coil spring 420, or the like. As shown in FIG. 8 , when the elastic member 400 is a torsion spring 410, a mounting post is provided on the hub 100, and the torsion spring 410 is attached to the mounting post. One elastic arm 411 of the torsion spring 410 abuts against the hub 100, and the other elastic arm 411 abuts against the fixed member 300. When the blade 200 is attached, the fixed member 300 moves from the second position to the first position, compressing the elastic member 400. Once the blade 200 is attached in place, the elastic force of the elastic member 400 is restored, returning the fixed member 300 from the first position to the second position. 4 and 11, the elastic member 400 may be a coil spring 420. A mounting groove 350 is formed on the fixing member 300, and the coil spring 420 is mounted in the mounting groove 350. The mounting groove 350 may be arranged to extend in an arc along the central axis of the fixing member. One end of the coil spring 420 abuts against the interior of the hub, and the other end abuts against the groove wall of the mounting groove 350. As a result, the coil spring 420 supports the hub and applies elastic force to the fixing member to move the fixing member from the first position to the second position. Specifically, a position limiting wall 140 is formed inside the hub. The position limiting wall 140 is arranged to surround the central axis of the hub. There is a certain gap between the position limiting wall 140 and the outer peripheral wall of the hub, and a guide groove 150 is formed in the gap. The entire guide groove 150 forms a ring shape coaxial with the hub 100. The shape of the guide groove 150 matches the shape of the fixing member, and the fixing member is mounted within the guide groove 150, determining the position of the fixing member via the guide groove 150. The fixing member slides relatively along the guide groove 150 and is switched between a first position and a second position by the guiding action of the guide groove 150. A connecting post 160 is provided in the guide groove 150. The connecting post 160 can be installed parallel to the axial direction of the hub. A through-slot 351 is formed on the mounting groove 350, extending in an arc shape along the central axis of the fixing member and penetrating the side wall of the mounting groove 350 in the axial direction of the fixing member. The connecting post 160 is drilled into the through-slot 351.When the fixed member rotates relative to the hub, the connecting post 160 slides relatively along the through groove 351, and the engagement between the connecting post 160 and the through groove 351 guides the rotation of the fixed member. When the coil spring 420 is attached to the attachment groove 350, one end of the coil spring 420 abuts on the connecting post 160 and the other end abuts on the groove wall of the attachment groove 350. The coil spring 420 applies elastic force to the fixed member with the connecting post 160 as support. Here, one, two, or more attachment grooves 350 can be provided on the fixed member, and the multiple attachment grooves 350 can be arranged sequentially along the circumferential direction of the fixed member. A coil spring 350 is attached to each attachment groove 350, and elastic force is simultaneously applied to the fixed member through the multiple coil springs 420, ensuring that the fixed member is stably held in the second position.

[0027] In some specific embodiments of the present invention, one of the hub 100 and the end of the blade 200 is provided with a guide rod 501, and the other is provided with a sliding groove 502. As shown in FIGS. 2 and 7, in this embodiment, the hub 100 is provided with the guide rod 501, and the end of the blade 200 is provided with the sliding groove 502. The guide rod 501 and the sliding groove 502 extend along the blade 200 in the insertion direction of the mounting part 110. When the end of the blade 200 is inserted into the mounting part, the guide rod 501 slides into the sliding groove 502, guiding the installation direction of the blade 200 via the guide rod 501 and the sliding groove 502, and at the same time, limiting the vibration of the blade 200 along the axial direction relative to the hub 100. The hub 100 and the blade 200 are provided with an engagement protrusion 503, and the other is provided with an engagement recess 504. 2 and 7, in this embodiment, an engaging recess 504 is provided at the end of the blade 200, and an engaging protrusion 503 is provided on the hub 100. The engaging protrusion 503 matches the shape of the engaging recess 504. When the blade 200 is inserted into the insertion portion 110 to a predetermined position, the engaging protrusion 503 engages with the engaging recess 504, which indicates that the blade 200 is attached to the predetermined position.

[0028] In some specific embodiments of the present invention, as shown in Figures 12, 13, 14, and 16, the light assembly 700 further includes a light assembly 700, a first connecting member 800, a second connecting member 910, a connecting holder 920, and a motor 600. The first connecting member 800 and the second connecting member 910 are respectively attached to both axial sides of the hub 100. The light assembly 700 includes a light housing 710. A light-emitting element such as a light board is attached inside the light housing 710. As shown in the figures, an insertion hole 720 is formed in the upper part of the light housing 710, and an insertion rod 721 is formed in the side wall of the insertion hole 720. The insertion rod 721 extends in an arc shape around the center line of the light housing 710. The first connecting member 800 is attached to the hub 100 using a fastener such as a screw. A first connecting groove 810 is formed in the side wall of the first connecting member 800. The first connecting groove 810 is formed in an inverted L shape. During installation, the first connecting member 800 is inserted into the insertion hole 720 and can rotate relative to the insertion hole 720. After the first connecting member 800 is inserted into the insertion hole 720, the light housing 710 is rotated relative to the first connecting member 800, and the insertion rod 721 on the first connecting member 800 slides into and engages with the first connecting groove 810. By fitting the insertion rod 721 into the first connecting groove 810, the first connecting member 800 and the light housing 710 are fixed relative to each other. That is, the light housing 710 is separated from the first connecting member 800 along the axial direction of the hub 100, and the light assembly 700 is fixed onto the hub 100. The motor 600 is mounted in the connection holder 920. The motor 600 is connected to the hub 100 and drives the hub 100 to rotate. The interior of the connection holder 920 is hollow, and a protrusion 921 is provided on the inner wall of the connection holder 920. A second connection groove 911 is provided on the side wall of the second connection member 910. The second connection groove 911 may be L-shaped.
