Referring to fig. 1 to 7, the present invention provides a ceiling fan 100, the ceiling fan 100 may be a ceiling fan or an embedded air conditioner, and the ceiling fan 100 includes:

The shell 10 comprises a panel assembly 11, wherein an air inlet 111 and an air outlet 112 surrounding the air inlet 111 are formed in the panel assembly 11;

the wind-guiding ring 20 is mounted on the upper surface of the panel assembly 11, the wind-guiding ring 20 comprises a plurality of wind-guiding plates 21 and a plurality of wind-guiding auxiliary plates 22, two ends of each wind-guiding plate 21 are respectively connected with one wind-guiding auxiliary plate 22 in a sliding manner, and each wind-guiding auxiliary plate 22 is connected with the panel assembly 11 in a sliding manner so that the wind-guiding auxiliary plates 22 slide along the radial direction of the wind outlet 112; the method comprises the steps of,

the driving devices are installed in the housing 10, and each driving device is configured to drive one air deflector 21 and/or one air guiding sub-plate 22 to move along the radial direction of the air outlet 112, so that the air guiding ring 20 stretches and contracts along the radial direction of the air outlet 112 to change the opening of the air outlet 112.

Specifically, in the present embodiment, the shape of the housing 10 is very large, for example, the housing 10 is cylindrical, square-cylindrical, etc., and the shape of the housing 10 is not particularly limited; for better installation of the ceiling machine 100 into a wall, the cylindrical arrangement.

Wherein the housing 10 includes a cylindrical housing body 12, and the lower end of the housing body 12 is open, the housing body 12 forms a containing cavity inside for the fan 40, the heat exchanger 50 and other components of the ceiling fan 100, and the heat exchanger 50 is annular, and separates the containing cavity to form an air inlet channel inside the heat exchanger 50 and an air outlet channel outside the heat exchanger 50; the shell 10 further comprises a panel assembly 11, wherein the panel assembly 11 is used for covering an opening at the lower end of the shell body 12, and the panel assembly 11 is provided with an air inlet 111 communicated with the air inlet channel and an air outlet 112 communicated with the air outlet channel; the air inlet 111 is arranged in the central area of the panel assembly 11, and the shape of the air inlet 111 is various, such as circular, square, polygonal, etc., preferably, the air inlet 111 is in a ring shape, thus being convenient for the air inlet 111 to inlet, and avoiding the occurrence of the problem that turbulence is formed at the air inlet 111 due to the existence of corners of the air inlet 111; the air outlet 112 is disposed annularly around the air inlet 111, and the shape of the air outlet 112 may be various, such as a circle, a square, a polygon, etc., preferably, the shape of the air outlet 112 is a circle, and the air outlet 112 is disposed outside the air inlet 111, so that a larger air outlet area is easily formed, and the air outlet range of the ceiling fan 100 is further enlarged.

The air guide ring 20 is installed in the housing 10 and located on the upper surface of the panel assembly 11, that is, the air guide ring 20 is located on the air inlet side of the air outlet 112 of the panel assembly 11; the air guide ring 20 may be mounted on the inner peripheral side of the air outlet 112 or the outer peripheral side of the air outlet 112, and preferably, the air guide ring 20 is mounted on the inner peripheral side of the air outlet 112, which is advantageous for reducing the volume of the ceiling fan 100. And the air guiding ring 20 is telescopically arranged along the radial direction of the air outlet 112, so that the relative position of the air guiding ring 20 and the air outlet 112 can be changed by adjusting the size of the air guiding ring 20, so as to change the area of the air guiding ring 20 covering the air outlet 112 and further change the air outlet area of the air outlet 112.

Specifically, the air guiding ring 20 includes a plurality of air guiding plates 21 and a plurality of air guiding sub-plates 22, and two ends of each air guiding plate 21 are respectively slidably connected with one end of one air guiding sub-plate 22, that is, the air guiding ring 20 is formed by splicing a plurality of assemblies formed by the air guiding plates 21 and two air guiding sub-plates 22; and each of the wind guide sub-plates 22 is slidably coupled to the assembly of the panels 113 in the radial direction of the air outlet 112, so that the wind guide sub-plates 22 at both ends of the wind guide plate 21 can move only in the radial direction of the air outlet 112. When the air deflector 21 moves along the radial direction of the air outlet 112, the two auxiliary guide plates also move along the radial direction of the air outlet 112 along with the air deflector 21, and when the air deflector 21 moves toward the outer side of the air outlet 112, the length of the air deflector 21 between the two air deflector sub-plates 22 needs to be increased, and since the two air deflector sub-plates 22 are both slidably connected with one end of the air deflector 21, the air deflector 21 can slide relative to the two air deflector sub-plates 22 respectively, the length of the assembly formed by the air deflector 21 and the two air deflector sub-plates 22 is increased, and the radial expansion and contraction of the whole air deflector 20 along the air outlet 112 can be realized.

It should be noted that, central angles corresponding to any two air deflectors 21 in the plurality of air deflectors 21 may be equal or unequal; similarly, the central angles corresponding to any two of the air guiding sub-plates 22 in the plurality of air guiding sub-plates 22 may be equal or different. In the embodiment of the present invention, the central angles corresponding to any two air deflectors 21 are equal, and the central angles corresponding to any two air guiding sub-plates 22 are also equal. The arrangement is convenient for the production and manufacture of the air deflector 21 and the air guide auxiliary plate 22.

In addition, when the air guiding ring 20 stretches along the radial direction of the air outlet 112, the air guiding sub-plates 22 at two ends of the air guiding plate 21 only slide along the radial direction of the air outlet 112, and the two sub-plates do not displace along the circumferential direction of the air outlet 112, that is, the central angle corresponding to the assembly formed by the air guiding plate 21 and the two air guiding sub-plates 22 is unchanged, so that the movement modes of the air guiding plate 21 and the two air guiding sub-plates 22 are simplified, the structure of the air guiding ring 20 can be simplified, and the production and the manufacture of the air guiding ring 20 are facilitated.

In addition, the two adjacent wind-guiding auxiliary plates 22 may be mutually spliced or connected, and there is no limitation on how the two adjacent wind-guiding auxiliary plates 22 are specifically arranged, so that when a plurality of assemblies formed by the wind-guiding plates 21 and the two wind-guiding auxiliary plates 22 are spliced, a complete circular ring can be formed, that is, it is ensured that no area where wind cannot be guided exists in the wind-guiding ring 20.

The driving devices are all installed in the housing 10, and each driving device is configured to drive the air deflector 21 and/or the air guiding sub-plate 22 to move along the radial direction of the air outlet 112, so that the air guiding ring 20 integrally stretches along the radial direction of the air outlet 112. That is, each driving device may drive one air deflector 21 to move along the radial direction of the air outlet 112, so as to drive the air deflector sub-plates 22 at two ends of the air deflector 21 to move along the radial direction of the air outlet 112, and simultaneously move along the extending direction of the air deflector 21 relative to the air deflector 21, so that the assembly formed by the air deflector 21 and the two air deflector sub-plates 22 stretches and contracts, and the air deflector ring 20 stretches and contracts along the radial direction of the air outlet 112.

Of course, the driving device may also drive the air guide sub-plates 22 at two ends of the air guide plate 21 to move along the radial direction of the air outlet 112, and when the two air guide sub-plates 22 move along the radial direction of the air outlet 112, the two ends of the air guide plate 21 have the partial velocity along the radial direction of the air outlet 112, and the combined velocity direction of the combined velocity of the two ends of the air guide plate 21 is also along the radial direction of the air outlet 112, so that the air guide plate 21 moves along the radial direction of the air outlet 112 under the driving of the two air guide sub-plates 22; and because the wind deflector 21 is slidably connected with the two wind guiding sub-plates 22, when the wind deflector 21 moves along with the two wind guiding sub-plates 22, the wind deflector 21 slides relative to the two wind guiding sub-plates 22, so that the length of the assembly formed by the wind deflector 21 and the two wind guiding sub-plates 22 is changed, and the wind guiding ring 20 can stretch along the radial direction of the air outlet 112. In addition, the driving device may also drive the air deflector 21 and the two air guiding sub-plates 22 to move simultaneously, so that the assembly formed by the air deflector 21 and the two air guiding sub-plates 22 moves along the radial direction of the air outlet 112. Here, the manner in which the plurality of driving devices drive the air guide ring 20 to extend and retract in the radial direction of the air outlet 112 is not particularly limited.

It should be noted that, the assembly formed by the air deflector 21 and the two air guiding sub-plates 22 may move along the radial direction of the outlet independently, that is, the user may control the movement of the assembly formed by the air deflector 21 and the two air guiding sub-plates 22 at the corresponding positions according to the actual situation, so as to be beneficial to improving the air guiding effect of the air guiding ring 20, further providing more choices for the user, and being beneficial to improving the experience of the user.

According to the technical scheme of the invention, the annular air outlet 112 is arranged on the panel assembly 11 of the ceiling fan 100, the air guide ring 20 is arranged on the upper surface of the panel assembly 11, the air guide ring 20 comprises a plurality of air guide plates 21 and a plurality of air guide auxiliary plates 22 which are arranged in an arc shape, each air guide auxiliary plate 22 is in sliding connection with one end of one air guide plate 21, each air guide auxiliary plate 22 is in sliding connection with the panel assembly 11 along the radial direction of the air outlet 112, so that the arc length of a combined piece formed by one air guide plate 21 and two air guide auxiliary plates 22 can be adjusted, the air guide plates 21 and/or the air guide auxiliary plates 22 are driven by a driving device to move along the radial direction of the air outlet 112, so that the whole air guide ring 20 can stretch along the radial direction of the air outlet 112, the area of the air guide ring 20 is changed, the air outlet 112 is blocked, the opening of the air outlet 112 can be changed, the opening of the air outlet 112 can be adjusted, and the user can adjust the opening of the air outlet 112.

In order to increase the air supply range of the air outlet 112, in an embodiment of the invention, referring to fig. 1, the upper surface of the air guiding ring 20 is disposed obliquely downward from the inner side of the air guiding ring 20 to the outer side of the air guiding ring 20. The upper surface of the air guiding ring 20 may be a plane, or may be a curved surface protruding upward, etc., which is not particularly limited herein. It should be noted that, when the upper surface of the air guiding ring 20 is in direct contact with the air in the air outlet channel, and the upper surface of the air guiding ring 20 can change the flow direction of the air contacting with the air guiding ring, this also makes the upper surface of the air guiding ring 20 have an air guiding effect, and the upper surface of the air guiding ring 20 is set to be inclined downward, this makes the upper surface of the air guiding ring 20 extend in the radial direction of the air outlet 112 and shield part of the air outlet 112, and before passing through the air outlet 112, part of the air in the air outlet channel contacts with the upper surface of the air guiding ring 20, and the air contacting with the upper surface of the air guiding ring 20 is guided by the upper surface of the air guiding ring 20 to flow out of the air outlet 112 along the extending direction of the upper surface of the air guiding ring 20, compared with setting the upper surface of the air guiding ring 20 to be inclined downward, in this embodiment, the upper surface of the air guiding ring 20 is set to be inclined downward, and the air guiding ring 112 is not inclined downward, and the air guiding ring is connected to the air outlet 100, and the air guiding ring is prevented from being inclined, and the air outlet 100 is further connected to the air outlet; and the appearance of whirl can also increase the air-out noise of smallpox machine 100, will the upper surface of wind-guiding ring 20 sets up to the inclined plane and can also reduce to a certain extent the air-out noise of smallpox machine 100, and then is favorable to improving user's experience.

In order to facilitate the installation of the air guide ring 20, referring to fig. 2, the panel assembly 11 includes a panel 113 and an annular sleeving plate 114 extending upward from the panel 113, and it should be noted that the annular sleeving plate 114 is convexly disposed at a position between the air inlet 111 and the air outlet 112 of the panel assembly 11. The housing 10 further includes a mounting bracket 13 above the panel 113, the mounting bracket 13 including a pressing plate 131 disposed in a ring shape, and an annular abutment plate 132 extending downward from an inner side edge of the pressing plate 131.

When the air guide ring 20 is installed, the air guide ring 20 is sleeved on the annular sleeve plate 114 of the panel assembly 11, then the annular abutting plate 132 of the mounting bracket 13 is abutted with the annular sleeve plate 114, and at this time, the panel 113 of the panel assembly 11 and the pressing plate 131 of the mounting bracket 13 are arranged at intervals along the up-down direction, so that the air guide ring 20 positioned outside the annular abutting plate 132 or the annular sleeve plate 114 is limited. Because annular butt plate 132 with annular sleeve joint plate 114 adopts the mode of cup jointing to connect, cup joints has easy dismounting, swift advantage, has just so made things convenient for the dismouting of wind-guiding ring 20, and then is favorable to improving the installation effectiveness of wind-guiding ring 20, still be favorable to the maintenance and the change of wind-guiding ring 20.

Further, the annular sleeve plate 114 and the annular butt plate 132 may be fixedly connected by other connectors such as a buckle, a screw, etc., so that the connection between the annular sleeve plate 114 and the annular butt plate 132 is firmer, thereby preventing the mounting bracket 13 from falling off from the panel 113 bracket, and further preventing the air guide ring 20 from falling off from the panel assembly 11.

In order to facilitate the sliding of the two air guiding sub-plates 22 relative to the air guiding plate 21, in an embodiment of the present invention, referring to fig. 8 and 9, two ends of the air guiding plate 21 are respectively provided with a first sliding rail 211 extending along the extending direction of the air guiding plate 21, and the air guiding sub-plates 22 are correspondingly provided with a first sliding block 221 slidably connected with the first sliding rail 211. The first sliding rail 211 and the first sliding block 221 are slidably connected, and can perform guiding function when the air guiding sub-plate 22 slides relative to the air guiding plate 21, so that even if a gap between the air guiding sub-plate 22 and the air guiding plate 21 is relatively large, the air guiding sub-plate 22 does not generate relatively large jump when sliding relative to the air guiding plate 21, and further, smooth expansion and contraction of the air guiding ring 20 along the radial direction of the air outlet 112 is ensured; simultaneously, the noise generated when the air deflector 21 and the air guide auxiliary plate 22 slide relatively can be reduced, so that the noise generated when the ceiling machine 100 works can be reduced, and the experience of a user can be improved.

The first sliding rail 211 may be formed by a groove formed in the air deflector 21, a T-shaped projection protruding out of the air deflector 21, or a sliding rail mounted on the air deflector 21, and the manner of forming the first sliding rail 211 is not particularly limited, and the manner of forming the first sliding rail 211 is various; accordingly, the structure of the first slider 221 is disposed corresponding to the structure of the first sliding rail 211.

Further, the first sliding rail 211 extends along a tangential direction of the end of the air deflector 21. The arrangement makes the first sliding rail 211 be a linear rail, and compared with a curved rail, the linear rail is easier to form, so that the first sliding rail 211 on the air deflector 21 is convenient to arrange; in addition, the resistance of the first slider 221 sliding in the linear track is smaller than the resistance of the first slider 221 sliding in the curved track, so that the friction between the first slider 221 and the first sliding rail 211 is reduced, and the first slider 221 can slide along the first sliding rail 211 more smoothly, and the noise generated when the first slider 221 slides along the first sliding rail 211 can be reduced.

Obviously, in order to facilitate the sliding of the two air guiding sub-plates 22 relative to the air guiding plate 21, in another embodiment of the present invention, the air guiding sub-plates 22 are connected to the air guiding plate 21 in a sleeved manner. It should be noted that, the diameter of the circle corresponding to the air guiding sub-plate 22 is equal to the diameter of the circle corresponding to the air guiding plate 21, so that after the air guiding sub-plate 22 is sleeved with the air guiding plate 21, the air guiding sub-plate 22 can slide along the extending direction of the air guiding plate 21, that is, the circumference of the circle corresponding to the air guiding plate 21. And the air deflector 21 and the air deflector 22 are connected in a sleeved mode, so that when the air deflector 22 slides relative to the air deflector 21, larger jump is not generated, and further stable sliding of the air deflector 22 relative to the air deflector 21 is ensured.

It may be understood that the sleeving connection between the air guiding auxiliary plate 22 and the air guiding plate 21 may be that the air guiding auxiliary plate 22 is sleeved at the end of the air guiding plate 21, or that the end of the air guiding plate 21 is sleeved in the air guiding plate 21, or that the air guiding plate 21 and the air guiding auxiliary plate 22 are mutually sleeved. In the embodiment of the present invention, the air deflector 21 and the air deflector 22 are sleeved with each other, specifically, the air deflector 21 includes an upper air deflector 212 and a lower cover plate 213 covering the lower surface of the upper air deflector 212, and the end of the lower cover plate 213 is in clearance fit with the end of the upper air deflector 212 to form a sliding channel; the air guiding sub-plate 22 comprises a sliding plate 222 slidably mounted in the sliding channel, and an upper air guiding sub-plate 223 connected with one side of the sliding plate 222 and covering the upper cover plate. The arrangement is such that the connection between the wind deflector 21 and the wind deflector 22 is stable.

In order to facilitate the air guiding sub-plate 22 to slide along the radial direction of the air outlet 112 relative to the panel assembly 11, in an embodiment of the present invention, referring to fig. 9 and 10, a plurality of second sliding rails 115 extending along the radial direction of the air outlet 112 and arranged along the circumferential direction of the air outlet 112 are disposed on the upper surface of the panel assembly 11; correspondingly, each of the air guiding sub-plates 22 is provided with a second sliding block 224 slidably connected to one of the second sliding rails 115.

The second sliding rail 115 and the second sliding block 224 are slidably connected, and can play a guiding role when the air guiding sub-plate 22 slides along the radial direction of the air outlet 112 relative to the panel assembly 11, so that even if a gap between the air guiding sub-plate 22 and the panel assembly 11 is relatively large, the air guiding sub-plate 22 does not generate relatively large jump when sliding along the radial direction of the air outlet 112 relative to the panel assembly 11, and smooth expansion and contraction of the air guiding ring 20 along the radial direction of the air outlet 112 is ensured.

The second slide rail 115 may be formed by a groove formed in the panel assembly 11, a T-shaped projection protruding from the upper surface of the panel assembly 11, or a slide rail mounted on the upper surface of the panel assembly 11, and the second slide rail 115 may be formed in a variety of ways, and the specific manner of forming the second slide rail 115 is not limited herein; accordingly, the structure of the second slider 224 is disposed corresponding to the structure of the second sliding rail 115. In the embodiment of the present invention, the second sliding rail 115 is formed by a sliding groove concavely formed on the panel assembly 11, and the second sliding block 224 is formed by a protruding block convexly formed on the air guiding sub-plate 22.

In order to enable the air guiding sub-plate 22 to slide more smoothly with respect to the panel assembly 11, in an embodiment of the present invention, the free end of the second slider 224 is provided with a ball 226, and the ball 226 is in rolling contact with the bottom of the corresponding sliding groove on the panel 113 when the second slider 224 is mounted in the sliding groove. When the air guide auxiliary plate 22 slides along the radial direction of the air outlet 112, the balls 226 roll relative to the sliding groove, so that the sliding friction between the second sliding block 224 and the bottom of the sliding groove is changed into rolling friction, and the second sliding block 224 can slide along the sliding groove smoothly, so that the air guide auxiliary plate 22 can slide along the radial direction of the air outlet 112 smoothly relative to the panel 113.

Obviously, in order to enable the air guiding sub-plate 22 to slide more smoothly relative to the panel assembly 11, a roller 226 may be sleeved on the second sliding block 224, and the roller 226 may contact with two groove walls disposed opposite to the sliding groove when the second sliding block 224 is mounted in the sliding groove. When the air guide auxiliary plate 22 slides along the radial direction of the air outlet 112, the roller 226 rolls along two opposite groove walls of the sliding groove, so that the sliding friction between the second slider 224 and the two opposite groove walls of the sliding groove becomes rolling friction, and the second slider 224 can smoothly slide along the sliding groove, thereby ensuring that the air guide auxiliary plate 22 can smoothly slide along the radial direction of the air outlet 112 relative to the panel 113.

It should be noted that, in order to enable the air guiding sub-plate 22 to slide more smoothly relative to the panel assembly 11, the two embodiments may be combined, that is, the free end of the second slider 224 is provided with the ball 226, and meanwhile, the second slider 224 is sleeved with the roller, so that when the second slider 224 slides along the sliding groove, only rolling friction exists between the second slider 224 and the sliding groove, and thus friction force between the second slider 224 and the sliding groove is greatly reduced, so that the second slider 224 can slide more smoothly along the sliding groove, and further, the air guiding sub-plate 22 can slide smoothly along the radial direction of the air outlet 112 relative to the panel 113.

In the embodiment of the present invention, the form of the driving device 30 may be various, for example, the driving device 30 is formed by a motor and a link assembly, and further, the driving device 30 is formed by a motor, a rocker, a slider, etc., which are not illustrated herein.

In the first embodiment of the present invention, referring to fig. 3, each of the driving devices 30a includes a motor 31a31a, a gear 32a and a rack 33a, wherein the motor 31a is fixedly mounted on the housing 10, the gear 32a is sleeved on an output shaft of the motor 31a, the rack 33a extends along a radial direction of the air outlet 112 and is fixedly connected with the air deflector 21, and the rack 33a is meshed with the gear 32 a.

When the motor 31a drives the gear 32a to rotate, the rack 33a moves along the radial direction of the air outlet 112 under the driving of the gear 32a, the rack 33a drives the air deflector 21 to move along the radial direction of the air outlet 112 while moving, the air deflector 22 at two ends of the air deflector 21 slides along the radial direction of the air outlet 112 under the driving of the air deflector 21, and the two air deflector 22 only slide along the radial direction of the air outlet 112, so that the air deflector 21 slides relative to the two air deflector 22 when the air deflector 21 moves along the radial direction of the air outlet 112, so that the assembly formed by the air deflector 21 and the two air deflector 22 stretches along the radial direction of the air outlet 112, and further the air deflector 20 stretches along the radial direction of the air outlet 112.

Obviously, the rack 33a may be connected to the air guiding sub-plate 22, or the air guiding plate 21 and the air guiding sub-plate 22 are both connected to the rack 33a, and the driving device 30a is provided with a gear 32a and a motor 31a corresponding to each rack 33a, so that the air guiding plate 21 and the air guiding sub-plate 22 can move simultaneously under the driving of the corresponding motor 31a, and detailed moving processes of the air guiding plate 21 and the air guiding sub-plate 22 are not repeated here.

In the second embodiment of the present invention, referring to fig. 4, the air deflector 21 is provided with a driving rail 214 extending along the extending direction thereof; the driving device 30b includes a motor 31b, a rocker 32b, and a driving block 33b, wherein the motor 31b is fixedly mounted on the housing 10, one end of the rocker 32b is connected with the motor 31b, the driving block 33b is disposed at one end of the rocker 32b away from the motor 31b, and the driving block 33b is slidably connected with the driving rail 214.

When the motor 31b drives the rocker 32b to swing, the rocker 32b moves along with the motor 31b in a circular manner, the driving block 33b arranged at one end of the rocker 32b away from the motor 31b moves along with the rocker 32b in a circular manner, and the radius corresponding to the movement track of the driving sliding block is unequal to the radius corresponding to the air deflector 21, so that the sliding block drives the air deflector 21 to move along the radial direction of the air outlet 112 when sliding relative to the driving sliding rail 214 on the air deflector 21, and the expansion and contraction of the assembly formed by the air deflector 21 and the two air deflector auxiliary plates 22 are realized, and the radial expansion and contraction of the air deflector 20 along the air outlet 112 are further realized.

It should be noted that, in the embodiment of the present invention, other solutions except the solution where the rocker 32b extends along the radial direction of the air outlet 112 and the length of the rocker 32b is equal to the radius of the air outlet 112 are all within the scope of protection of the present application.

In the third embodiment of the present invention, referring to fig. 5, the driving device 30c includes a motor 31c, a first connecting rod 32c and a second connecting rod 33c, wherein the motor 31c is fixedly mounted on the housing 10, one end of the first connecting rod 32c is connected with the motor 31c, one end of the first connecting rod 32c away from the motor 31c is pivoted with the second connecting rod 33c, and one end of the second connecting rod 33c away from the first connecting rod 32c is pivoted with the air deflector 21.

When the motor 31c rotates, the motor 31c drives the first link 32c to swing, the second link 33c pivoted to the first link 32c swings together with the driving of the first link 32c, and when the second link 33c swings along with the first link 32c, the end of the second link 33c away from the first link 32c moves linearly in a reciprocating manner along the radial direction of the air outlet 112, so that the air deflector 21 pivoted to the second link 33c moves reciprocally along the radial direction of the air outlet 112 under the driving of the second link 33 c. When the air guide plates 21 move along the radial direction of the air outlet 112, the two air guide sub-plates 22 respectively disposed at the two ends of the air guide plate 21 are driven by the air guide plate 21 to move along the radial direction of the air outlet 112, and the air guide sub-plates 22 disposed at the two ends of the air guide plate 21 are slidably connected with the panel assembly 11, so that the air guide sub-plates 22 disposed at the two ends of the air guide plate 21 can only slide along the radial direction of the air outlet 112, that is, the air guide plate 21 moves along the radial direction of the air outlet 112 and slides along the extending direction of the air guide plate 21, but the movement is opposite, and when the air guide plate 21 is taken as a reference, the air guide sub-plates 22 can be considered to slide along the extending direction of the air guide plate 21 and slide along the extending direction of the air guide plate 21. The expansion and contraction of the assembly formed by the air deflector 21 and the two air guiding sub-plates 22 are realized, so that the radial expansion and contraction of the air guiding ring 20 along the air outlet 112 is realized, and the change of the size of the air outlet 112 of the ceiling fan 100 is realized.

Considering that the first link 32c requires a larger working space if the first link 32c moves along with the motor 31c, in this embodiment of the present invention, the motor 31c preferably uses a stepper motor 31c, and since the stepper motor 31c can rotate forward and backward, the swinging angle of the first link 32c can be controlled by adjusting the rotation angle of the stepper motor 31c, so as to reduce the working space of the first link 32c, thereby being beneficial to reducing the overall volume of the ceiling fan 100. Of course, when the first link 32c moves within a limited range of swing angles, the air guide ring 20 can completely open the air outlet 112 or completely cover the air outlet 112 along the radial direction of the air outlet 112.

In the fourth embodiment of the present invention, referring to fig. 6 and 7, the driving device 30d includes a motor 31d, a rotating wheel 32d sleeved on an output shaft of the motor 31d, and the motor 31d and the rotating wheel 32d assembly may be mounted on the air deflector 21 or the air guiding sub-plate 22, or mounted on the air deflector 21 and the air guiding sub-plate 22 at the same time; a first guide is provided on the panel assembly 11 corresponding to the motor 31d and the wheel 32d assembly,

When the motor 31d drives the rotating wheel 32d to rotate, the rotating wheel 32d moves along the first guide member, so that the air guiding sub-plate 22 moves along the radial direction of the air outlet 112 along with the rotating wheel 32d, and when the air guiding plates 21 located between the two air guiding plates 21 move along the radial direction of the air outlet 112, both ends of the air guiding plates 21 have the speed along the radial direction of the air outlet 112, and the speeds at both ends of the air guiding plates 21 are combined to be along the radial direction of the air outlet 112, so that the air guiding plates 21 can move along the radial direction of the air outlet 112, and the air guiding ring 20 can stretch along the radial direction of the air outlet 112.

The first guide may be a rack, an elongated groove, or other structural members, and the first guide is not particularly limited herein. In an embodiment of the present invention, a surface of the panel assembly 11 facing the air guiding ring 20 is provided with a plurality of first sliding grooves extending radially along the air outlet 112, and each of the first sliding grooves forms the first guiding member; the rotating wheel 32d is installed in the first chute and abuts against the groove wall of the first chute along the length direction.

In order to facilitate the sliding of the air deflector 21 relative to the two air deflector auxiliary plates 22, two ends of the air deflector 21 are respectively provided with a second guide piece extending along the extending direction of the air deflector 21; the driving mechanism further comprises a driving wheel 33d sleeved on the output shaft of the motor 31d, a driven wheel 34d installed on the air guide auxiliary plate 22 and in transmission connection with the second guide piece, and a driving belt 35d for connecting the driving wheel 33d and the driven wheel 34d in transmission.

It should be noted that the second guide member not only has a guiding function, but also has a transmission relationship with the driven wheel 34 d. When the motor 31d drives the driving wheel 33d to rotate, the distance between the driving wheel 33d and the driven wheel 34d is fixed, so that the driven wheel 34d is driven by the transmission belt 35d to perform rotary motion; and the driven wheel 34d is in driving connection with the second guide member, that is, when the driven wheel 34d rotates, the driven wheel rolls relative to the second guide member, and since the air guiding auxiliary plate 22 can only move along the radial direction of the air outlet 112 and the air guiding plate 21 is in sliding connection with the air guiding auxiliary plate 22, the air guiding plate 21 can slide relative to the air guiding auxiliary plate 22, so that the air guiding plate 21 can slide relative to the two air guiding auxiliary plates 22 while ensuring the air guiding auxiliary plate 22 to move along the radial direction of the air outlet 112, and the air guiding ring 20 can extend and retract along the radial direction of the air outlet 112.

The second guide may be a rack, an elongated groove, or other structural members, and the second guide is not particularly limited herein. In an embodiment of the present invention, two ends of the air deflector 21 are provided with second sliding grooves along the extending direction of the air deflector 21, and each second sliding groove forms the second guiding element; the driven wheel 34d is mounted in the second chute and abuts against a slot wall of the second chute along the length direction thereof.

When the motor 31d drives the driven wheel 34d to rotate, the driven wheel 34d rolls along the groove wall in the length direction of the second chute and generates an interaction friction force with the groove wall of the second chute, but the air guiding auxiliary plate 22 can only move along the radial direction of the air outlet 112, that is, the position of the driven wheel 34d along the extending direction of the air guiding plate 21 cannot be changed, so that the air guiding plate 21 slides relative to the air guiding auxiliary plate 22, and the length of the assembly formed by the air guiding plate 21 and the two air guiding auxiliary plates 22 is increased, and therefore, when the air guiding ring 20 stretches along the radial direction of the air outlet 112, the air guiding ring 20 still can guide air at all positions of the air outlet 112.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
