[0039] It should be noted that the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0040] In combination Figures 1-15 As shown in the drawings, the embodiments of the present disclosure provide an air outlet assembly 10, comprising a mounting ring 300, a fixed ring 100, a driving ring 200 and a driving gear 240, wherein the mounting ring 300 is provided with a first buckling part 310 in the radial direction; the fixed ring 100 is fixed to the mounting ring 300, and the fixed ring 100 and the mounting ring 300 are oppositely arranged to form a driving space, and the fixed ring 100 is provided with a second buckling part 150 in the radial direction, and the second buckling part 150 and the first buckling part 310 form a gear mounting space; the driving ring 200 is rotatably arranged in the driving space, and the driving ring 200 is provided with a gear tooth; the driving gear 240 is rotatably arranged in the gear mounting space and is engaged with the driving ring 200, and the driving gear 240 drives the driving ring 200 to rotate when it rotates.

[0041] In the embodiments of the present disclosure, the mounting ring 300 is used to arrange a plurality of movable guide vanes, and the driving ring 200 is used to drive the plurality of movable guide vanes to move, and the mounting ring 300 is used to fix the air outlet assembly 10 to a preset mounting position.

[0042] Specifically, the air outlet assembly 10 is sequentially provided with the mounting ring 300, the driving ring 200 and the fixing ring 100 in the air outlet direction. The inner ring of the mounting ring 300 defines a first air outlet, which is used to be connected with an air outlet of the preset mounting position. Correspondingly, the driving ring 200 and the mounting ring 300 also have hollow inner rings corresponding to the first air outlet.

[0043] The driving ring 200 rotates while the mounting ring 300 and the fixing ring 100 remain fixed. The fixing ring 100 and the mounting ring 300 are oppositely arranged and are spaced apart by a preset distance, so as to form a driving space between the fixing ring 100 and the mounting ring 300, and the driving ring 200 is rotatably arranged in the driving space. In this way, the rotation of the driving ring 200 occurs in the interior of the air guide assembly, and the rotation of the driving ring 200 is not easy to interfere with other components of the preset mounting position. The driving space formed by the mounting ring 300 and the fixing ring 100 can make the air outlet assembly 10 have a neat appearance.

[0044] The outer ring of the driving ring 200 is configured with gear teeth, and the rotation of the driving ring 200 is driven in the same plane as the driving ring 200, so as to reduce the thickness of the air outlet assembly 10 as a whole. The driving gear 240 is engaged with the gear teeth of the outer ring of the driving ring 200, and the driving ring 200 rotates by a corresponding number of teeth when the driving gear 240 rotates. In this way, a smaller motor can also achieve the driving of the driving ring 200, thereby reducing the volume of the air outlet assembly 10 and reducing the cost of the air outlet assembly 10.

[0045] In order to realize the installation and positioning of the driving gear 240, the mounting ring 300 is provided with a first buckling portion 310 extending in the radial direction, and the fixing ring 100 is provided with a second buckling portion 150 extending in the radial direction. The first buckling portion 310 and the second buckling portion 150 define a gear installation space. The gear installation space is provided with a relief opening on the side facing the driving ring 200, so as to enable the driving gear 240 to be engaged with the driving ring 200. With such a setting form, the driving gear and the driving ring are located in the same plane, the driving ring performs a circular motion, and the space required for movement is small, and the space utilization rate of the air conditioner is high. The rotation of the driving gear is not easy to interfere with other components by fixing the driving gear through the first buckling portion and the second buckling portion. The first buckling portion and the second buckling portion serve as visual identification marks of the fixing ring and the mounting ring, which facilitates the assembly of the air outlet assembly.

[0046] Optionally, the air outlet assembly further comprises a driving motor, the driving motor is located on the side of the second buckling portion for connecting the plurality of movable guide vanes, and the output shaft of the driving motor extends into the gear installation space.

[0047] In this way, the driving motor does not occupy much installation space, and the air outlet assembly 10 can be attached to the preset installation position through the installation ring.

[0048] Optionally, an accommodation groove is arranged on the outward side of the first fastening part 310; the air outlet assembly 10 further comprises a driving motor, and the driving motor is embedded in the accommodation groove.

[0049] The air outlet assembly 10 further comprises a driving motor, which is configured to provide power for the rotation of the driving ring 200. Specifically, an accommodation groove is arranged on the outward side of the first fastening part 310, and the driving motor is embedded in the accommodation groove and the output shaft of the driving motor penetrates through the first fastening part 310 to be connected to the driving gear 240. In this way, the driving motor is arranged on the side of the fixing ring 100 where the first baffle 400 is arranged, and the side of the installation ring 300 away from the first baffle 400 is relatively flat. In this way, the structure of the driving assembly can be more compact.

[0050] Optionally, the first part of the outer edge of the driving ring 200 is provided with a gear.

[0051] When the driving ring 200 drives the first baffle 400 to move between the first position and the second position, the angle of the rotation of the driving ring 200 is fixed, and the outer edge of the driving ring 200 is partially provided with a gear. In this way, the machining difficulty of the driving ring 200 can be reduced. In addition, the driving ring 200 is partially provided with a gear, so that even if the rotation of the driving motor is abnormal, the driving ring 200 will not rotate beyond its rotation range, thereby avoiding the rotation of the first baffle 400 beyond its rotation range. In this way, the safety of the air outlet assembly 10 can be improved.

[0052] Optionally, a plurality of positioning bosses 330 are arranged on the side of the installation ring 300 facing the fixing ring 100 along the circumference of the first air outlet, and the fixing ring 100 is provided with a plurality of positioning matching parts 170 corresponding to the positioning bosses 330, and the plurality of positioning matching parts 170 are one-to-one correspondingly lapped on the top of the positioning bosses 330.

[0053] The driving ring 200 rotates between the installation ring 300 and the fixing ring 100, and a space needs to be left for the rotation of the driving ring 200 between the installation ring 300 and the fixing ring 100. Therefore, a plurality of positioning bosses 330 are arranged on the installation ring 300 along the circumference thereof, and a plurality of positioning matching parts 170 are arranged on the fixing ring 100 along the circumference thereof. The side of the positioning boss 330 facing the fixing ring 100 abuts against the side of the positioning matching part 170 facing the installation ring 300. In this way, the relative distance and coaxiality of the installation ring 300 and the fixing ring 100 can be facilitated.

[0054] Optionally, the first clamping portion 310 is an integral structure with one of the plurality of positioning bosses 330, and the second clamping portion 150 is an integral structure with one of the plurality of positioning matching portions 170.

[0055] With such a setting form, the injection molding of the fixing ring 100 and the mounting ring 300 is facilitated. In addition, the positioning matching portions 170 and the positioning bosses 330 serve as reinforcing ribs, which can improve the structural strength of the first and second clamping portions 150.

[0056] Optionally, the top of the positioning boss 330 is configured with a positioning pin 331, and the positioning matching portion 170 is configured with a positioning hole 171 corresponding to the positioning pin 331, and the positioning pin 331 is inserted into the positioning hole 171.

[0057] The side of the positioning boss 330 facing the fixing ring 100 is the top of the positioning platform, and the top of the positioning boss 330 is configured with a positioning pin 331. The side of the positioning matching portion 170 facing the positioning boss 330 is configured with a positioning hole 171, and the positioning pin 331 is inserted into the positioning hole 171, which facilitates more accurate installation and positioning between the mounting ring 300 and the fixing ring 100.

[0058] Optionally, the side of the fixing ring 100 facing outward is provided with a plurality of first pivots 110 along the circumference of the first air outlet; the air outlet assembly 10 further comprises a plurality of first flaps 400, which are rotatably connected to the fixing ring 100 one by one through the plurality of first pivots 110, and the axis around which the first flaps 400 rotate is parallel to the plane in which the first air outlet is located; the driving ring 200 is provided with a plurality of driving portions, and the plurality of first flaps 400 are each provided with a driving matching portion, and the driving ring 200 drives the plurality of first flaps 400 to rotate when the driving ring 200 rotates.

[0059] The air outlet assembly 10 provided by the embodiments of the present disclosure comprises a chassis 11 and a plurality of first flaps 400. The chassis 11 is configured with a first air outlet in the middle, and the plurality of first flaps 400 are connected to the chassis 11 and distributed along the circumference of the first air outlet.

[0060] Taking one of the first flaps 400 as an example, the first end of the first flap 400 is rotatably connected to the chassis 11. The axis around which the first flap 400 rotates is parallel to the plane in which the first air outlet is located. When the first flap 400 rotates, the second end can move along the axis that is close to or away from the first air outlet.

[0061] When the plurality of first baffles 400 are all moved to the first position in the direction close to the axis of the first air outlet, the second ends of the plurality of first baffles 400 are gathered into a conical cylinder with two open ends. The end with a larger cross section of the conical cylinder is the first end, and the end with a smaller cross section is the second end. The first end of the conical cylinder is in abutment with the first air outlet of the bottom disc 11, and the second end of the conical cylinder serves as the air outlet of the air outlet assembly 10 as a whole. At this time, the air outlet cross section of the air outlet assembly 10 is reduced, and the air entering the conical cylinder is blown to a farther distance under the gathering and guiding effect of the plurality of first baffles 400, so as to realize the converging telefocus air supply.

[0062] It should be noted that if only the cross section of the air outlet is reduced, the flow rate of the air at the air outlet is high, but the airflow is turbulent, and a lot of kinetic energy is lost due to molecular collision near the air outlet, so the air supply distance is short. However, using the air outlet assembly 10 provided by the embodiment of the present disclosure, under the gathering of the plurality of first baffles 400, each first baffle 400 plays a flow guiding role, and the air can form a laminar flow under the wall effect of the first baffle 400, so that the energy loss is small during movement, so that the air can be blown to a farther position.

[0063] When the plurality of first baffles 400 are all moved to the second position in the direction away from the axis of the first air outlet, the second ends of the plurality of first baffles 400 are spread apart. The projection of the second end of each first baffle 400 on the plane of the first air outlet is located outside the first air outlet. At this time, the air outlet of the bottom disc 11 serves as the air outlet of the air outlet assembly 10 as a whole, and the air outlet cross section of the air outlet assembly 10 is large. The air is directly blown out through the air outlet of the bottom disc 11 and is not disturbed by the plurality of first baffles 400, so that the air volume of the air conditioner is large.

[0064] It should be noted that when the plurality of first baffles 400 are moved between the first position and the second position, the projection of the second end of the plurality of first baffles 400 on the plane of the air outlet is located inside the first air outlet. The plurality of first baffles 400 are gathered but cannot be enclosed into a closed conical cylinder. At this time, the first air outlet of the bottom disc 11 serves as the air outlet of the air outlet assembly 10 as a whole, and the second end of the plurality of first baffles 400 is located on the air outlet path to disturb the airflow. The air after being disturbed by the plurality of first baffles 400 is blown to a short distance and the wind feeling is soft, that is, the sharp-piercing disturbance air supply is realized.

[0065] The chassis 11 comprises a fixed ring 100, an inner ring of the fixed ring 100 defining a first air outlet. A plurality of first pivot portions 110 are circumferentially and spacedly arranged on one side of the fixed ring 100, and a plurality of first baffles 400 are one-to-one correspondingly rotatably connected to the fixed ring 100 through the plurality of first pivot portions 110; a driving ring 200 coaxial with the fixed ring 100 and rotatable relative to the fixed ring 100, the driving ring 200 being provided with a plurality of first driving portions 210, and each of the plurality of first baffles 400 being provided with a first driving cooperation portion 420, the plurality of first driving portions 210 and the plurality of first driving cooperation portions 420 one-to-one correspondingly cooperating, and the driving ring 200 being driven to move the second ends of the plurality of first baffles 400 in a direction along or away from an axis of the first air outlet when the driving ring 200 rotates.

[0066] In order to realize the fixation and driving of the plurality of first baffles 400, the chassis 11 comprises the fixed ring 100 and the driving ring 200. The fixed ring 100 is used to provide mounting positions for the plurality of first baffles 400, that is, the plurality of first baffles 400 are rotatably connected to the fixed ring 100. The driving ring 200 is used to drive the plurality of first baffles 400 to move synchronously to the first position or the second position or a position between the first position and the second position.

[0067] One side of the fixed ring 100 is provided with the plurality of first pivot portions 110, the plurality of first pivot portions 110 one-to-one correspond to the plurality of first baffles 400, and the first baffles 400 are rotatably connected to the fixed ring 100 through the first pivot portions 110. Exemplarily, the first pivot portion 110 is a shaft sleeve, the first end of the first baffle 400 has a rotating shaft 430, and the rotating shaft 430 cooperates with the shaft sleeve, so as to realize the rotatable connection of the first baffle 400. In another example, the first pivot portion 110 is the rotating shaft 430, and the first baffle 400 is provided with a shaft sleeve, the shaft sleeve cooperates with the rotating shaft 430, so as to realize the rotatable connection of the first baffle 400.

[0068] The driving ring 200 is arranged in parallel with the fixed ring 100, and the driving ring 200 can be planarly rotated relative to the fixed ring 100. The driving ring 200 is provided with the plurality of first driving portions 210, each of the plurality of first baffles 400 is provided with the first driving cooperation portion 420, and the plurality of first driving portions 210 and the plurality of first driving portions 210 one-to-one correspondingly cooperate. When the driving ring 200 rotates, the first driving portion 210 moves along a circumference in a plane where the driving ring 200 is located, drives the first driving cooperation portion 420 to move, and thus drives the first baffle 400 to rotate around the first pivot portion 110.

[0069] The chassis 11 comprises a fixing ring 100, through which the plurality of first baffles 400 are fixed, facilitating the installation and positioning of the plurality of first baffles 400; the plurality of first baffles 400 can be simultaneously moved to the first position or the second position through the driving ring 200, facilitating the air outlet assembly 10 to change the air outlet form; the driving ring 200 is coaxial with the fixing ring 100 and can rotate relative to the fixing ring 100, and the driving ring 200 requires less space for movement, which is conducive to reducing the volume of the air outlet assembly 10.

[0070] Using the air outlet assembly 10 disclosed in the present application, the air supply distance and the wind feeling intensity can be adjusted through the movement of the plurality of first baffles 400, and the air outlet form is various; the positions of the plurality of first baffles 400 can be continuously changed, and the air supply distance and the wind feeling intensity can be adjusted steplessly, which can meet the personalized needs of users in different use scenarios.

[0071] Optionally, the air outlet assembly 10 further comprises a wind blocking cylinder 600 arranged on the chassis 11, the first end of the wind blocking cylinder 600 is connected with the first air outlet, and the plurality of first baffles 400 are located in the inner circle of the wind blocking cylinder 600.

[0072] When the plurality of first baffles 400 are all moved to the second position, there will be a gap between the adjacent two first baffles 400. Although the plurality of first baffles 400 are located at the position avoiding the first air outlet, the wind guiding effect of the first baffles 400 is weakened. Therefore, the wind blocking cylinder 600 is arranged on the chassis 11, the first end of the wind blocking cylinder 600 is connected with the first air outlet. The plurality of first baffles 400 are located in the inner circle of the wind blocking cylinder 600. When the plurality of first baffles 400 are gathered into a conical cylinder, the wind blocking cylinder 600 will not affect the focusing air supply effect of the plurality of first baffles 400; when the plurality of first baffles 400 are moved to the second position, the plurality of first baffles 400 and the wind blocking cylinder 600 are both extended along the air outlet direction, and jointly play the role of guiding wind. By arranging the wind blocking cylinder 600, the wind guiding effect can be achieved together with the plurality of first baffles 400, thereby avoiding air leakage between the adjacent two first baffles 400 of the air outlet assembly 10.

[0073] Optionally, the length of the wind blocking cylinder 600 is greater than or equal to the length of the first baffle 400.

[0074] The plurality of first baffles 400 are movement components, and the wind blocking cylinder 600 located in the outer circle of the plurality of first baffles 400 can not only avoid the movement of the first baffles 400 interfering with other components in the preset installation position, but also can physically protect the plurality of first baffles 400, avoiding damage to the plurality of first baffles 400 during installation and transportation. The length of the wind blocking cylinder 600 is greater than or equal to the length of the first baffle 400, and the first baffle 400 is completely located in the wind blocking cylinder 600 when rotated to any position, so that the wind blocking cylinder 600 can better play the protection role.

[0075] Optionally, the inner wall of the wind deflector 600 is configured with a plurality of embedded grooves, the shape of the embedded grooves is matched with the shape of the first baffle 400, and the plurality of second baffles 500 are embedded in the plurality of embedded grooves one by one when moving to the second position.

[0076] When the plurality of first baffles 400 rotate to the second position, there are gaps between the plurality of first baffles 400, and the inner wall is uneven. This will cause air kinetic energy loss and affect the air volume of the air outlet assembly 10. The inner wall of the wind deflector 600 is configured with a plurality of embedded grooves, and the plurality of first baffles 400 are embedded in the plurality of embedded grooves one by one when moving to the first position. The inner wall is relatively flat when the wind deflector 600 and the plurality of first baffles 400 jointly guide the wind, which can improve the air outlet effect of the air outlet assembly 10.

[0077] Optionally, the inner wall of the wind deflector 600 is configured with a plurality of flow guide ribs.

[0078] When the plurality of first baffles 400 and the wind deflector 600 jointly guide the wind, the adjacent two flow guide ribs form a wind guide groove, and the air is divided into a plurality of strands flowing along the plurality of wind guide grooves. Under the guidance of the plurality of wind guide grooves, even if there is a certain vortex in the air, the air as a whole moves in the air outlet direction. This can reduce the kinetic energy loss of the air flowing through the air outlet assembly 10, thereby improving the air supply distance of the air outlet assembly 10.

[0079] Optionally, the first driving part 210 includes a first guide groove 211, and the distance from the first guide groove 211 to the first air outlet gradually increases from the first end to the second end; the first driving cooperation part 420 includes a first driving pin 421, the first driving pin 421 extends into the first guide groove 211, and when the driving ring 200 rotates in the first direction, the distance from the first driving pin 421 to the first air outlet increases, thereby driving the second end of the first baffle 400 to be close to the axis of the first air outlet.

[0080] When the driving ring 200 rotates, the first guide groove 211 rotates relative to the first driving pin 421, and the first driving pin 421 slides relative to the first guide groove 211 under the limitation of the first blocking piece 400 by the first pivot part 110. When the driving ring 200 rotates in the first direction, the first end of the first guide groove 211 gradually changes to the second end of the first guide groove 211 in cooperation with the first driving pin 421. The distance between the first driving pin 421 and the axis of the air outlet gradually increases under the limiting action of the first guide groove 211. The second end of the first blocking piece 400 gradually decreases the distance to the axis of the air outlet with the first driving pin 421 as one end of the lever and the second end of the first blocking piece 400 as the other end of the lever. The second ends of the plurality of first blocking pieces 400 converge inward to achieve the aggregated telephoto air outlet. When the driving ring 200 rotates in the second direction, the distance between the first driving pin 421 and the axis of the air outlet gradually decreases, and the second ends of the plurality of first blocking pieces 400 diverge to achieve the windless air outlet.

[0081] Optionally, the fixed ring 100 is provided with a plurality of first avoiding grooves 141, and the plurality of first avoiding grooves 141 correspond to the plurality of first blocking pieces 400 one by one. The first driving pin 421 of the first blocking piece 400 extends into the first guide groove 211 of the driving ring 200 through the first avoiding groove 141.

[0082] The first driving pin 421 rotates when the first blocking piece 400 rotates, and the first driving pin 421 extends into the first guide groove 211 of the driving ring 200 through the avoiding groove of the fixed ring 100. With such a setting form, the first driving pin 421 does not need to protrude out of the driving ring 200 to cooperate with the first guide groove 211 of the driving ring 200, which simplifies the structure of the air outlet assembly 10.

[0083] Optionally, the length direction of the first avoiding groove 141 is along the radial direction of the fixed ring 100, and the width is matched with the size of the first driving pin 421.

[0084] The first driving pin 421 moves along the radial direction of the fixed ring 100 when rotating, and the length direction of the first avoiding groove 141 is along the radial direction of the fixed ring 100, so as to leave a rotating space for the rotation of the first driving pin 421. The width of the first avoiding groove 141 is matched with the size of the first driving pin 421, so as to limit the movement of the first driving pin 421 in the radial direction of the fixed ring 100, thereby avoiding the friction between the first guide groove 211 and the first driving pin 421 from driving the first driving pin 421 to rotate along the circumferential direction of the fixed ring 100 when the driving ring 200 rotates. In this way, the reliability of the operation of the air outlet assembly 10 can be improved.

[0085] Optionally, the outer side of the fixed ring 100 is provided with a plurality of second pivot portions 130 along the circumference of the first air outlet, and the plurality of second pivot portions 130 are located outside the plurality of first pivot portions 110; the air outlet assembly 10 further comprises a plurality of second baffle plates 500, which are connected to the fixed ring 100 through the plurality of second pivot portions 130 in a one-to-one correspondence, and the second end of each second baffle plate 500 can move in a direction close to or away from the axis of the first air outlet; when the second end of each first baffle plate 400 moves inward to the first position, the plurality of second baffle plates 500 are gathered inward and fit on the outer side of the plurality of first baffle plates 400; when the second end of each first baffle plate 400 moves outward to the second position, each second baffle plate 500 is located between two adjacent first baffle plates 400.

[0086] Optionally, the fixed ring 100 is provided with a plurality of second pivot portions 130 along the circumference of the first air outlet, and the plurality of second pivot portions 130 are located outside the plurality of first pivot portions 110; the plurality of second baffle plates 500 are connected to the fixed ring 100 through the plurality of second pivot portions 130 in a one-to-one correspondence.

[0087] The plurality of first pivot portions 110 are used to connect the plurality of first baffle plates 400, and the plurality of second pivot portions 130 are used to connect the plurality of second baffle plates 500. The plurality of first baffle plates 400 and the plurality of second baffle plates 500 are connected to the fixed ring 100, so that the structure of the air outlet assembly 10 can be simplified and the volume of the air outlet assembly 10 can be reduced.

[0088] Optionally, the driving ring 200 is provided with a plurality of second guide grooves 221, and the first end of the second baffle plate 500 is provided with a second driving pin 521, which extends into the second guide groove 221; when the driving ring 200 rotates bidirectionally, the second baffle plate 500 also rotates bidirectionally.

[0089] The first guide groove 211 is used to drive the first baffle plate 400 to rotate, and the second guide groove 221 is used to drive the second baffle plate 500 to rotate. The cooperation between the second driving pin 521 and the second guide groove 221 can refer to the cooperation between the first driving pin 421 and the first guide groove 211. With such a setting form, when the driving ring 200 rotates, the plurality of first baffle plates 400 and the plurality of second baffle plates 500 are simultaneously driven to rotate, and the integration degree of the air outlet assembly 10 is improved.

[0090] Optionally, the fixed ring 100 is provided with a plurality of second avoiding grooves 142, and the plurality of second avoiding grooves 142 are located outside the plurality of first avoiding grooves 141; the second driving pin 521 extends into the second guide groove 221 through the second avoiding groove 142.

[0091] When the second baffle 500 rotates, the second driving pin 521 also rotates, and the second driving pin 521 penetrates the second avoiding slot 142 of the fixing ring 100 and extends into the second guide slot 221 of the driving ring 200. In this way, the second driving pin 521 can be matched with the second guide slot 221 of the driving ring 200 without extending beyond the driving ring 200, thus simplifying the structure of the air outlet assembly 10.

[0092] Optionally, the mounting ring 300 is provided with a plurality of third avoiding slots 341 corresponding to the plurality of first avoiding slots 141, and the first driving pin 421 extends into the third avoiding slot 341 through the first guide slot 211.

[0093] The third avoiding slot 341 and the first avoiding slot 141 are matched to limit the movement of the first driving pin 421 along the circumferential direction of the fixing ring 100. In this way, the rotation of the first driving pin 421 can be better limited in the preset rotation plane, and the local deformation or fracture of the first driving pin 421 caused by excessive force can be avoided.

[0094] Optionally, the mounting ring 300 is provided with a plurality of fourth avoiding slots 342 corresponding to the plurality of second avoiding slots 142, and the second driving pin 521 extends into the fourth avoiding slot 342 through the second guide slot 221.

[0095] The fourth avoiding slot 342 and the second avoiding slot 142 are matched to limit the movement of the second driving pin 521 along the circumferential direction of the fixing ring 100. In this way, the rotation of the second driving pin 521 can be better limited in the preset rotation plane, and the local deformation or fracture of the second driving pin 521 caused by excessive force can be avoided.

[0096] Optionally, the mounting ring 300 is provided with a third avoiding slot 341, and the length direction of the third avoiding slot 341 is along the radial direction of the mounting ring 300, and the width of the third avoiding slot 341 is matched with the size of the first driving pin 421.

[0097] In this way, the third avoiding slot 341 of the mounting ring 300 and the first avoiding slot 141 of the fixing ring 100 jointly limit the movement of the first driving pin 421 in the radial direction of the fixing ring 100. In this way, the movement of the first driving pin 421 along the circumferential direction of the fixing ring 100 can be further avoided. Optionally, the angle between the first guide slot 211 and the axis of the first air outlet gradually increases from the first end to the second end.

[0098] The first guide slot 211 has two opposite inner edges in the thickness direction of the first guide slot 211 along the axis of the first air outlet. The included angle between the first guide slot 211 and the axis of the first air outlet refers to the included angle between the inner edge of the first guide slot 211 along the axis of the first air outlet and the axis of the first air outlet. If the two are parallel, the first driving pin 421 will interfere with the inner edge of the first guide slot 211 when it rotates. If a larger fitting allowance is provided between the first guide slot 211 and the first driving pin 421, it may cause the position of the first driving pin 421 to be unclear when the driving ring 200 rotates. Specifically, when the first baffle 400 is located at the first position, it blocks more of the air outlet, and at this time, the first driving pin 421 also tilts more. When the first baffle 400 is located at the second position, the length direction of the first baffle 400 is along the axis of the first air outlet, and at this time, the first driving pin 421 tilts less and is generally parallel to the axis of the first air outlet. The included angle between the first guide slot 211 and the air outlet gradually increases from the first end to the second end, and the degree of tilt of the first driving pin 421 during the rotation of the first baffle 400 is adapted to the degree of tilt of the first guide slot 211. In this way, on the one hand, the friction between the first guide slot 211 and the first driving pin 421 can be reduced, and on the other hand, the first driving pin 421 can be better rotated to a preset angle.

[0099] Optionally, the first baffle 400 comprises a plate body 410, a rotating shaft and a first driving pin 421, wherein the width of the plate body 410 gradually decreases from the first end to the second end; the rotating shaft is arranged at the first end of the plate body 410; and the first driving pin 421 is arranged at the first end of the plate body 410 or the rotating shaft.

[0100] A plurality of first baffles 400 can be spliced into a conical cylinder. As for a single first baffle 400, the width of the second end is smaller than the width of the first end. Specifically, the first baffle 400 comprises a plate body 410, which serves as the main body of the first baffle 400 and plays a role in enclosing and guiding air when a plurality of first baffles 400 are spliced. The width of the plate body 410 gradually decreases from the first end to the second end, so that the first baffles 400 can be spliced into a sealed conical cylinder when they are gathered. The rotating shaft is arranged at the first end of the plate body 410, and the rotating shaft cooperates with the first pivot portion 110 of the fixed ring 100 to enable the first baffle 400 to be rotatably connected to the fixed ring 100. The first driving pin 421 serves as the first driving fitting portion 420, one end of which is connected to the first end of the plate body 410 or the rotating shaft, and the other end extends into the first guide slot 211. With such a setting form, the driving ring 200 can drive the first baffle 400 to rotate.

[0101] Optionally, the plate body 410 comprises a wind-blocking portion 411 and a mounting portion 412, wherein the width of the wind-blocking portion 411 gradually decreases from the first end to the second end; and the mounting portion 412 is connected to the first end of the baffle plate, and there is a first included angle between the mounting portion 412 and the wind-blocking portion 411.

[0102] The plate body 410 comprises a wind blocking portion 411 and a mounting portion 412. The wind blocking portions 411 of the plurality of first baffles 400 are spliced to form a conical barrel. The mounting portion 412 is used to fix the first baffles 400 to the bottom disc 11.

[0103] The width of the wind blocking portion 411 gradually decreases from the first end to the second end, which is conducive to the splicing of the wind blocking portions 411 of the plurality of first baffles 400.

[0104] In the case where the plurality of first baffles 400 enclose a conical barrel, in the length direction, the wind blocking portion 411 is generally along the axial direction of the first air outlet, and the mounting portion 412 is generally along the radial direction of the first air outlet. There is a first included angle between the mounting portion 412 and the wind blocking portion 411, so that the mounting portion 412 can be attached to the bottom disc 11. The mounting portion 412 is attached to the bottom disc 11, and the fixing of the first baffle 400 can be realized without opening a hole in the bottom disc 11, which can avoid air leakage of the air outlet assembly 10. The mounting portion 412 is attached to the bottom disc 11, and the contact area between them is large, which can improve the fixing effect of the bottom disc 11 on the first baffle 400.

[0105] Optionally, the first included angle is greater than 90 degrees.

[0106] In the case where the first included angle is equal to 90 degrees, the length direction of the mounting portion 412 is along the radial direction of the first air outlet, and the length direction of the wind blocking portion 411 is along the axial direction of the first air outlet. The first included angle is greater than 90 degrees, and in the case where the mounting portion 412 is attached to the bottom disc 11, the second end of the wind blocking portion 411 is inwardly gathered, so that the plurality of first baffles 400 are spliced into a conical barrel. With such a setting form, the fixing effect of the bottom disc 11 on the first baffle 400 can be further improved.

[0107] Optionally, the middle part of the wind blocking portion 411 is convex to the first air outlet.

[0108] The middle part of the wind blocking portion 411 is convex to the first air outlet, that is, the included angle between the conical barrel and the axis of the first air outlet gradually decreases from the first end to the second end. In the conical barrel, the increase of air flow velocity is more in the part close to the first end and less in the part close to the second end. The turbulence formed by the throttling and acceleration of air is more in the front section of the conical barrel, and the speed change is less in the rear section of the conical barrel. Under the wall effect of the rear end of the conical barrel, the air is rectified to reduce turbulence and increase laminar flow. After the air is blown out of the first conical barrel, it can be blown to a farther distance. With such a setting form, the air supply distance of the air outlet assembly 10 can be further improved.

[0109] Optionally, the inward side of the plate body 410 is configured with a wind guide protrusion 413 extending along the length direction of the first baffle 400.

[0110] The air guide protrusion 413 on the inner surface of the plate body 410 is wedge-shaped or triangular, and its width gradually decreases from the first end to the second end of the plate body 410. When the plurality of first baffles 400 are spliced, the two adjacent air guide protrusions 413 form an air guide groove. The air flowing in the cone cylinder is divided into multiple streams flowing along the plurality of air guide grooves by the air guide protrusions 413. Under the guidance of the plurality of first air guide grooves, the air as a whole moves in the air outlet direction even if there is a certain vortex. In this way, the influence of the air close to the inner wall of the cone cylinder on the flow of other parts of the air can be reduced, and the kinetic energy loss of the air in the cone cylinder can be reduced, thereby improving the air supply distance of the air outlet assembly 10.

[0111] Optionally, the plate body 410 is configured with two air guide protrusions 413, and an air guide groove is formed between the two adjacent air guide protrusions 413.

[0112] The plate body 410 is configured with two air guide protrusions 413, and more air guide grooves can be formed on the inner wall of the cone cylinder. In this way, the kinetic energy loss of the air in the cone cylinder can be further reduced, thereby improving the air supply distance of the air outlet assembly 10.

[0113] Optionally, the two air guide protrusions 413 are respectively close to the two side edges of the plate body 410, one side edge of the air guide protrusion 413 serves as the first splicing part 414, and when the plurality of first baffles 400 are spliced, the air guide protrusions 413 of the two adjacent first baffles 400 are spliced.

[0114] The two air guide protrusions 413 of the plate body 410 are close to the two side edges, and the air guide protrusions 413 simultaneously serve as the structural reinforcement of the first plate body 410. When the plurality of first baffles 400 are spliced, the first baffles 400 are not easy to deform; when the air flows through the cone cylinder, the first baffles 400 are not easy to vibrate.

[0115] After the air guide protrusions 413 are close to the two side edges of the plate body 410, the air guide protrusions 413 are preferably flush with the side edges of the plate body 410. In this way, the plate body 410 is thicker at the side edges. The thickened side edges serve as the first splicing part 414, and when the plurality of first baffles 400 are spliced, in a first aspect, the first baffles 400 are not easy to deform due to mutual contact; in a second aspect, the thickness of the side edges of the plate body 410 is relatively large, and the two adjacent first baffles 400 are not easy to misalign or have a flash joint when spliced.

[0116] Optionally, the outer side of the plate body 410 is configured with a wedge-shaped protrusion 440.

[0117] The outer side of the plate body 410 is configured with a wedge-shaped protrusion 440, and on a cross section of the first baffle 400, the air guide protrusion 413 on the inner side of the plate body 410 and the wedge-shaped protrusion 440 on the outer side make the structure have multiple bending structures, which can further improve the structural strength of the plate body 410.

[0118] Optionally, the width of the wedge-shaped protrusion 440 gradually increases from the first end to the second end of the plate body 410, the width of the air guide groove gradually increases from the first end to the second end of the plate body 410, and the wedge-shaped protrusion 440 corresponds to the air guide groove.

[0119] The width of the air guide groove gradually increases from the first end to the second end, and the width of the two air guide protrusions 413 adjacent to the air guide groove gradually decreases from the first end to the second end of the plate body 410. The width of the air guide groove gradually increases, and the air flow section in the air guide groove is gradually expanded when the air flows in the air guide groove. In this way, the vortex formed by the contact between the air in the air guide groove and the wall of the air guide groove can occur as much as possible in the air guide groove, reducing the kinetic energy loss caused by the contact between the vortex and the air in other positions. The wedge-shaped protrusion 440 corresponds to the air guide groove, so that the thickness of the plate body 410 is uniform throughout the plane. By adopting such a setting form, the structural strength of the first baffle 400 is improved while the weight of the first baffle 400 is reduced, and the cost of the air outlet assembly 10 is reduced.

[0120] Optionally, the rotating shaft is arranged at the end of the mounting portion 412 away from the air blocking portion 411.

[0121] The rotating shaft is arranged at the end of the mounting portion 412 away from the air blocking portion 411, and the rotation of the mounting portion 412 and the air blocking portion 411 is all located on one side of the rotating shaft 430 when the first baffle 400 rotates, so that the first baffle 400 is not easy to interfere with the chassis 11 when rotating.

[0122] Optionally, the fixing ring 100 is provided with a plurality of first connecting pieces 120 along the circumference of the first air outlet, the two ends of the first connecting piece 120 are provided with shaft holes, the axis of the shaft hole is perpendicular to the plane where the first air outlet is located, every two adjacent first connecting pieces 120 are taken as a first pivot portion 110, and the two ends of the rotating shaft of the first baffle 400 are respectively inserted into the two opposite shaft holes of the two adjacent first connecting pieces 120.

[0123] The two ends of the rotating shaft of the first baffle 400 are fixed by the two adjacent first connecting pieces 120, so that the first baffle 400 is not easy to deviate when rotating; the two ends of each first connecting piece 120 are connected with one first baffle 400, the number of connecting pieces is equal to the number of first baffles 400, and the structure of the fixing ring 100 is simple and has low processing difficulty.

[0124] Optionally, the shaft hole is provided with a clamping notch in the radial direction, and the rotating shaft of the first baffle 400 is clamped into the shaft hole along the clamping notch.

[0125] If the two ends of the rotating shaft are respectively arranged into the shaft hole along the axial direction of the rotating shaft, the rotating shaft will be elastically deformed during the assembly process, or the shaft hole needs to be provided with an assembly allowance for the rotating shaft. In this case, the first baffle 400 may be offset along the axial direction of the rotating shaft when rotating. The shaft hole is provided with a clamping gap in the radial direction, and the width of the clamping gap is smaller than the diameter of the rotating shaft. When the first baffle 400 is assembled, the rotating shaft is clamped into the shaft hole from the clamping gap in the radial direction, and then is gap-fitted with the shaft hole to realize the rotatable connection of the first baffle 400. By adopting such a setting form, the assembly of the first baffle 400 can be facilitated, and the installation precision of the first baffle 400 can be improved.

[0126] Optionally, the first connecting piece 120 is provided with a first shaft hole and a second shaft hole, and the first shaft hole and the second shaft hole have a second included angle therebetween.

[0127] The plurality of first baffles 400 can be gathered to form a conical barrel, and the rotating shafts of the plurality of first baffles 400 form a regular polygon, so that a shape with a larger area can be enclosed with less material. The rotating shaft of the first baffle 400 serves as one side of the regular polygon, and there is a certain included angle a between the two adjacent rotating shafts. In the case that the number of the first baffles 400 is n, the included angle a = 180°-(360° / n). Correspondingly, the second included angle between the first shaft hole and the second shaft hole is also a, so that the rotating shaft of the first baffle 400 can be better constrained, thereby making the plurality of first baffles 400 enclose a conical barrel with a larger air guide cross section at the bottom end.

[0128] Optionally, the first shaft hole and the second shaft hole are connected.

[0129] In this way, the injection difficulty of the first connecting piece 120 can be reduced, and the injection material of the first connecting piece 120 can be reduced, thereby reducing the cost of the air outlet assembly 10.

[0130] Optionally, the two side ends of the first baffle 400 are each provided with a first splicing part 414, and each two adjacent first baffles 400 can be spliced through the two first splicing parts 414.

[0131] When the plurality of first baffles 400 are all moved inward to the first position, the plurality of first baffles 400 are spliced to form a conical barrel. If there is a gap between the two adjacent first baffles 400, the air leakage caused by the gap will affect the air supply effect of the air outlet assembly 10. The two ends of each first baffle 400 are provided with a first splicing part 414, and the two adjacent first baffles 400 are spliced through the first splicing part 414. In this way, the air supply effect of the air outlet assembly 10 can be improved, and the noise generated by the air flowing through the gap between the two adjacent first baffles 400 can be reduced.

[0132] Optionally, the first splicing part 414 is made of an elastic material.

[0133] When the plurality of first baffles 400 are all moved inward to the first position, the first joints 414 between two adjacent first baffles 400 are elastically deformed. In this way, the air leakage of the tapered cylinder when the plurality of first baffles 400 are gathered can be further avoided.

[0134] Optionally, the air outlet assembly 10 further comprises a plurality of second baffles 500 arranged along the circumference of the first air outlet and located outside the plurality of first baffles 400. The first end of each second baffle 500 is rotatably connected to the bottom plate 11 so that the second end can move along the axis of the first air outlet. When the second end of each first baffle 400 is moved inward to the first position, the plurality of second baffles 500 are gathered inward and fit on the outer side of the plurality of first baffles 400. When the second end of each first baffle 400 is moved outward to the second position, each second baffle 500 is located between two adjacent first baffles 400.

[0135] When the plurality of first baffles 400 are moved away from the first position, a larger gap is formed between two adjacent first baffles 400. The air outlet assembly 10 is provided with two rings of baffles, i.e. the plurality of first baffles 400 in the inner ring and the plurality of second baffles 500 in the outer ring. The plurality of second baffles 500 are also arranged along the circumference of the first air outlet and each second baffle 500 is rotatably connected to the bottom plate 11. The second end of each second baffle 500 can move along the axis of the first air outlet.

[0136] When the plurality of first baffles 400 are moved inward to the first position, a first tapered cylinder is formed. When the plurality of second baffles 500 are moved inward to the first position, a second tapered cylinder is formed, which is located outside the first tapered cylinder. At this time, each second baffle 500 blocks the joint between two adjacent first baffles 400. In this way, the air leakage at the joint between two adjacent first baffles 400 can be further avoided.

[0137] When the plurality of first baffles 400 are moved outward to the second position, a cylinder is formed, and there is a gap between two adjacent first baffles 400. When the plurality of second baffles 500 are moved outward to the second position, a cylinder is formed, and each second baffle 500 is used to block the gap between two adjacent first baffles 400. In this way, the first baffles 400 and the second baffles 500 form a closed air guide cylinder. In this way, the air guiding effect of the air outlet assembly 10 when the plurality of first baffles 400 are in the second position can be improved.

[0138] When the plurality of first baffles 400 are between the first position and the second position, the second end of the first baffle 400 is projected in the plane of the first air outlet and is located in the first air outlet, and the second end of the first baffle 400 plays a spoiler role. At this time, the second end of the second baffle 500 is also projected in the plane of the first air outlet and is located in the first air outlet, and the second end of the second baffle 500 also plays a spoiler role. In this way, the sharp spoiler air supply effect of the air outlet assembly 10 can be further improved.

[0139] Optionally, when the driving ring 200 rotates in the first direction, the plurality of first baffles 400 and the plurality of second baffles 500 are both rotated inward, and the movement of the plurality of first baffles 400 is ahead of the rotation of the plurality of second baffles 500. When the driving ring 200 rotates in the second direction, the plurality of first baffles 400 and the plurality of second baffles 500 are both rotated outward, and the rotation of the plurality of second baffles 500 is ahead of the rotation of the plurality of first baffles 400.

[0140] When the driving ring 200 rotates in the first direction, the plurality of first baffles 400 and the plurality of second baffles 500 are both rotated inward, and the movement of the plurality of first baffles 400 is ahead of the rotation of the plurality of second baffles 500. That is, when the plurality of first baffles 400 and the plurality of second baffles 500 move inward, the plurality of first baffles 400 move first, and the plurality of second baffles 500 move later. In this way, a wind dispersing layer is formed between the first baffles 400 of the inner ring and the first baffles 400 of the outer ring. A part of the air entering the air outlet assembly 10 from the first air outlet first passes through the air guiding gap between the adjacent two first baffles 400 to enter the wind dispersing layer between the first baffle 400 and the second baffle 500, and then is blown out through the air guiding gap between the adjacent two second baffles 500. The air disturbance of the plurality of first baffles 400 and the air disturbance between the plurality of second baffles 500 have the wind dispersing layer as a buffer, and the air is mixed in the wind dispersing layer after being disturbed by the first baffle 400, and then is blown out after being disturbed by the second baffle 500. By adopting such a setting form, the wind dispersing layer can be formed, so that the plurality of first baffles 400 and the plurality of second baffles 500 can better cooperate to realize the sharp spoiler air supply function.

[0141] Similarly, when the driving ring 200 rotates in the second direction, the plurality of first baffles 400 and the plurality of second baffles 500 are both rotated outward, and the rotation of the plurality of second baffles 500 is ahead of the rotation of the plurality of first baffles 400. When the plurality of first baffles 400 and the plurality of second baffles 500 are both rotated outward, the plurality of second baffles 500 move first, and the plurality of first baffles 400 move later. In this way, a wind dispersing layer is also formed between the first baffles 400 of the inner ring and the second baffles 500 of the outer ring, so that the plurality of first baffles 400 and the plurality of second baffles 500 can better cooperate to realize the sharp spoiler air supply function.

[0142] With such a setting form, the movement of the plurality of first baffles 400 and the plurality of second baffles 500 has a certain time difference, so that the plurality of first baffles 400 and the plurality of second baffles 500 can form a wind dispersing interlayer, so that the plurality of first baffles 400 and the plurality of second baffles 500 can better cooperate to realize the sharp wedge disturbance function.

[0143] Optionally, the outer side of the first baffle 400 is provided with a wedge-shaped protrusion 440, and the wedge-shaped protrusion 440 is embedded between the two adjacent second baffles 500 when the first baffle 400 and the second baffle 500 are rotated to the second position.

[0144] When the plurality of first baffles 400 and the plurality of second baffles 500 are moved to the second position, the air outlet is opened at the maximum opening degree, and at this time, the plurality of first baffles 400 and the plurality of second baffles 500 are enclosed into a cylindrical shape. The outer side of the first baffle 400 is provided with a wedge-shaped protrusion 440, and the two sides of the wedge-shaped protrusion 440 are respectively in abutment with the two adjacent second baffles 500. In this way, the wedge-shaped protrusion 440 can position the two second baffles 500 connected in series. The first baffle 400 of the inner ring and the second baffle 500 of the outer ring are locked by the wedge-shaped protrusion 440, so that the first baffle 400 or the second baffle 500 can be prevented from shaking.

[0145] Optionally, in the case where the bottom disc 11 comprises the fixed ring 100 and the driving ring 200, one side of the fixed ring 100 is provided with a plurality of second pivot portions 130 which are arranged in a circumferential direction and are located outside the plurality of first pivot portions 110, and the plurality of second baffles 500 are one-to-one correspondingly connected to the fixed ring 100 through the plurality of second pivot portions 130; the driving ring 200 is further provided with a plurality of second driving portions 220, the plurality of second baffles 500 are provided with second driving matching portions 520, and the plurality of second driving portions 220 and the plurality of second driving matching portions 520 are one-to-one correspondingly matched, so that the driving ring 200 drives the plurality of second baffles 500 to rotate when the driving ring 200 rotates.

[0146] One side of the fixed ring 100 is provided with a plurality of first pivot portions 110 and a plurality of second pivot portions 130, and the plurality of second pivot portions 130 are located outside the plurality of first pivot portions 110. The plurality of first pivot portions 110 are used to rotatably connect the plurality of first baffles 400 to the fixed ring 100, and the plurality of second pivot portions 130 are used to rotatably connect the plurality of second baffles 500 to the fixed ring 100. In this way, the installation and positioning of the plurality of first baffles 400 and the plurality of second baffles 500 can be realized through one fixed ring 100, and the structure of the air outlet assembly 10 is simplified.

[0147] The driving ring 200 is provided with a plurality of second driving portions 220, each of the second blocking pieces 500 is provided with a second driving matching portion 520, the plurality of second driving portions 220 and the plurality of second driving matching portions 520 are one-to-one corresponding, and the driving ring 200 drives the plurality of first blocking pieces 400 and the plurality of second blocking pieces 500 to rotate simultaneously when rotating. By adopting such a setting form, the plurality of first blocking pieces 400 and the plurality of second blocking pieces 500 can be driven to rotate simultaneously by one driving ring 200, which is beneficial to the synchronous movement of the plurality of first blocking pieces 400 and the plurality of second blocking pieces 500, and simplifies the structure of the air outlet assembly 10.

[0148] Optionally, the mounting ring 300 is configured with a first sliding groove 320; the fixing ring 100 is configured with a second sliding groove 160 corresponding to the first sliding groove 320; and the driving ring 200 is provided with a sliding column 230, both ends of the sliding column 230 respectively protrude out of two sides of the driving ring 200 and respectively extend into the first sliding groove 320 and the second sliding groove 160.

[0149] The driving ring 200 rotates in the driving space, and if the driving ring 200 and the mounting ring 300 or the fixing ring 100 are in surface friction, the friction force is relatively large, which affects the rotation of the driving ring 200. The mounting ring 300 is configured with a first sliding groove 320, and the fixing ring 100 is configured with a second sliding groove 160 corresponding to the first sliding groove 320. Both the first sliding groove 320 and the second sliding groove 160 are arc-shaped sliding grooves. The driving ring 200 is further provided with a sliding column 230, both ends of the sliding column 230 respectively protrude out of two sides of the driving ring 200 and respectively extend into the first sliding groove 320 and the second sliding groove 160. In this way, on the one hand, the sliding column 230 and the sliding groove cooperate to define a sliding track for the driving ring 200, which is beneficial to the rotation of the driving ring 200; on the other hand, the sliding column 230 and the sliding groove cooperate to reduce the rotation friction of the driving ring 200, so that the driving ring 200 can rotate more smoothly. In addition, both ends of the sliding column 230 respectively extend into the first sliding groove 320 and the second sliding groove 160, which is beneficial to keeping the relative distance between the driving ring 200 and the mounting ring 300 and the fixing ring 100. By adopting such a setting form, the concentricity and flatness of the driving ring 200 when rotating can be improved, which is beneficial to the synchronous rotation of the plurality of first blocking pieces 400 driven by the driving ring 200.

[0150] Optionally, when the sliding column 230 is located at the first end of the first sliding groove 320, the second ends of the plurality of first blocking pieces 400 rotate inwardly to the first position and gather into a conical cylinder with two open ends, at this time, the first air outlet is opened with the smallest opening degree; when the sliding column 230 is located at the second end of the first sliding groove 320, the second ends of the plurality of first blocking pieces 400 rotate outwardly to the second position to make the first air outlet open with the largest opening degree.

[0151] After the plurality of first baffles 400 are all rotated inwardly to the first position, if the driving ring 200 continues to rotate, it can cause the first baffles 400 to deform or flash, affecting the air outlet effect of the air outlet assembly 10. Therefore, the movement of the first baffles 400 needs to be limited. Since the rotation of the first baffles 400 is driven by the rotation of the driving ring 200, limiting the rotation of the driving ring 200 also simultaneously limits the rotation of the first baffles 400. Specifically, the first baffles 400 rotate between the first position and the second position, and correspondingly, the sliding column 230 slides between the first end and the second end of the first sliding groove 320. That is, the two ends of the first sliding groove 320 serve as the sliding limiting portion of the sliding column 230. With such a setting form, the first baffles 400 can be accurately moved to the first position or the second position, improving the accuracy of the movement control of the air outlet assembly 10 on the first baffles 400.

[0152] Optionally, when the sliding column 230 is located at the first end of the second sliding groove 160, the second ends of the plurality of first baffles 400 rotate inwardly to the first position and gather into a conical cylinder with two open ends, at this time the first air outlet is opened with the smallest opening degree; when the sliding column 230 is located at the second end of the second sliding groove 160, the second ends of the plurality of first baffles 400 rotate outwardly to the second position to make the first air outlet open with the largest opening degree.

[0153] Limiting the rotation of the driving ring 200 by the second sliding groove 160 and limiting the rotation of the driving ring 200 by the first sliding groove 320 can have the same effect.

[0154] Optionally, the outer ring of the fixed ring 100 is outwardly protruded to form an annular step 180, the plurality of second pivot portions 130 are arranged above the annular step 180, and the plurality of first pivot portions 110 are arranged on the inner ring of the fixed ring 100.

[0155] The outer ring of the fixing ring 100 is used to connect the plurality of second baffles 500, and the inner ring is used to connect the plurality of first baffles 400. When the plurality of first baffles 400 are spliced, gaps are prone to occur near the fixing ring 100, and the gaps include gaps between adjacent two first baffles 400 and gaps between the first baffles 400 and the fixing ring 100. Therefore, the fixing ring 100 is provided with an annular step 180, the outer ring of the fixing ring 100 is higher than the inner ring of the fixing ring 100, that is, the plurality of first connecting members 120 are arranged below the step, and the plurality of second connecting members are arranged above the step. The gaps of the plurality of first baffles 400 near the fixing ring 100 are shielded by the side wall of the annular step 180. By adopting such a setting form, the air-tightness of the plurality of first baffles 400 when spliced can be improved, so as to improve the air-out effect of the air-out assembly 10. In addition, the pivoting position of the first baffle 400 is below the step, and the pivoting position of the second baffle 500 is above the step, and even if the distance between them is close, they are not prone to rotating interference. The annular step 180 is arranged to reduce the distance between the first baffle 400 and the second baffle 500, thereby improving the air-tightness of the air-out assembly 10.

[0156] In combination Figures 1-2 As shown in the drawings, the embodiment of the present disclosure provides an air conditioner, which comprises a shell 710, a fan box and the above-mentioned air-out assembly 10. The shell 710 is configured with a containing space, and the shell 710 is provided with a second air-out port. The fan box is arranged in the containing space, and the fan box is provided with a third air-out port. The fan box and the shell 710 form a sandwich structure. The air-out assembly 10 is arranged in the sandwich structure, the first air-out port of the air-out assembly 10 corresponds to the third air-out port of the fan box, and the air-out direction of the air-out assembly 10 is towards the second air-out port.

[0157] The air conditioner comprises a shell 710 and a fan box, the shell 710 is configured with a receiving space, and the fan box is arranged in the receiving space. The independently arranged fan box can improve the air outlet static pressure of the air conditioner, and is beneficial to improving the air supply amount and increasing the air supply distance of the air conditioner. The shell 710 is provided with a second air outlet, and the fan box is provided with a third air outlet. The second air outlet is also used as the air outlet of the air conditioner as a whole. The first air outlet of the air outlet assembly 10 is opposite to the third air outlet of the fan box, the air outlet assembly 10 is arranged between the second air outlet and the third air outlet, and is used for guiding the air blown out of the third air outlet of the fan box to the second air outlet of the shell 710 at a certain angle. When the plurality of first baffles 400 move to the first position, the second ends of the plurality of first baffles 400 are gathered, so that the far focus air supply is realized; when the plurality of first baffles 400 move to the second position, the second ends of the plurality of first baffles 400 are scattered, so that the soft air supply in a large range is realized; when the plurality of first baffles 400 are between the first position and the second position, the sharp ends of the plurality of first baffles 400 play a role of flow disturbance, and the sharp wedge flow disturbance air supply is realized. In terms of structure, the fan box and the shell 710 form a sandwich, and the air outlet assembly 10 is arranged in the sandwich. In this way, the movement of the first baffles 400 or the second baffles 500 of the air outlet assembly 10 is neither in the fan box nor outside the shell 710, and the movement of each moving part of the air outlet assembly 10 is not easily interfered.

[0158] By using the air conditioner provided by the embodiment of the present disclosure, the air outlet cross section of the air outlet air duct formed by the air outlet assembly 10 is adjustable, so that the air supply distance and the wind feeling strength of the air conditioner can be changed by adjusting the cross section of the air outlet air duct. Specifically, in the case that the fan rotating speed is unchanged, the air supply distance is increased and the wind feeling is enhanced by reducing the cross section of the air outlet air duct, and the air supply distance is reduced and the wind feeling is weakened by increasing the cross section of the air outlet air duct. The cross section of the air outlet air duct is adjustable, so that the air supply distance and the wind feeling strength can be adjusted without changing the fan rotating speed, and the means for changing the air outlet form is increased. If the fan rotating speed and the air duct cross section are adjusted at the same time, a larger range of adjustment for the air supply distance and the wind feeling strength can be realized.

[0159] The air outlet assembly 10 has a moving part to change the air outlet cross section of the air outlet air duct, the air outlet assembly 10 is arranged in the sandwich, the movement of the moving part will not interfere with the parts in the fan box, the stability of the air conditioner in operation is improved, the movement of the moving part will not be presented outside the shell 710, and the appearance of the air conditioner is more beautiful, the shell 710 is opened to operate the air outlet assembly 10, and the assembly and maintenance of the air conditioner are facilitated.

[0160] Optionally, the fan box comprises a first box body 721, a second box body 722 and a fan, wherein the first box body 721 is provided with a third air outlet; the second box body 722 is in communication with the first box body 721, and the second box body 722 is provided with an air inlet; and the fan is arranged in the second box body 722 and used to drive air to flow from the air inlet to the third air outlet.

[0161] The first box body 721 is provided with the third air outlet, and the second box body 722 is provided with the air inlet. The third air outlet is far away from the air inlet, and air short circuit is not easy to occur, which is beneficial to better air circulation. The fan is arranged in the second box body 722, and when the fan rotates, air is driven to enter the second box body 722 from the air inlet and then is blown out from the third air outlet of the first box body 721. In the second box body 722, there is more turbulence under the stirring of the fan blades. After the air flows from the second box body 722 to the first box body 721, the first box body 721 has a rectifying effect, and the laminar flow in the air increases, so that the air can be blown to a farther distance after being blown out from the third air outlet. By adopting such a setting form, the running noise of the fan can be reduced, and the air supply distance of the air conditioner can be increased.

[0162] Optionally, the bottom end of the first box body 721 is opposite to the top end of the second box body 722, and the third air outlet and the air inlet are arranged on different sides of the fan box.

The third air outlet is high, and the coverage range of the air blown out is large. The third air outlet and the air inlet are located on different sides of the fan box, which can further avoid air return short circuit, thereby improving the air circulation effect. Exemplarily, in the use state of the air conditioner, the third air outlet is located on the front side of the fan box, and the air inlet is located on the rear side of the fan box. In the use state of the air conditioner, the front side faces the user, and the rear side does not face the user. In this way, the air conditioner has a more tidy appearance.

[0164] Optionally, the air conditioner further comprises a first air outlet duct 711, and the first air outlet duct 711 is arranged at the third air outlet and the bottom plate 11 is arranged at the outer ring of the first air outlet duct 711.

[0165] The bottom plate 11 of the air outlet assembly 10 is fixed to the fan box, and there are some structural protrusions and gaps at the abutting position of the bottom plate 11 and the fan box. The first air outlet duct 711 is arranged, which can smoothly guide the air blown out from the third air outlet into the air outlet duct of the air outlet assembly 10.
