[0037] 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.

[0038] In combination with Figures 1-15As shown, the air outlet assembly 10 provided by the embodiments of the present disclosure includes a fixed ring 100, a plurality of first baffles 400, and a plurality of second baffles 500. The fixed ring 100 is provided with a first air outlet, and the outer ring of the fixed ring 100 is provided with an annular step 180. The plurality of first baffles 400 are arranged along the circumference of the first air outlet, and the first end of each first baffle 400 is rotatably connected to the inner ring of the fixed ring 100. The second end of each first baffle 400 is movable in the direction of approaching or moving away from the axis of the first air outlet. When the second end of each first baffle 400 is rotated inward to a first position, the plurality of first baffles 400 are gathered into a conical cylinder with two open ends, so that the first air outlet is opened at a minimum opening degree. When the second end of each first baffle 400 is moved outward to a second position, the first air outlet is opened at a maximum opening degree. The plurality of second baffles 500 are 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 above the annular step 180, so that the second end is movable in the direction of approaching or moving away from 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. 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.

[0039] The air outlet assembly 10 provided by the embodiments of the present disclosure includes a base plate 11 and a plurality of first baffles 400. The base plate 11 is provided with a first air outlet in the middle, and the plurality of first baffles 400 are connected to the base plate 11 and arranged along the circumference of the first air outlet.

[0040] Taking one of the first baffles 400 as an example, the first end of the first baffle 400 is rotatably connected to the base plate 11. The rotation axis of the first baffle 400 is parallel to the plane in which the first air outlet is located. When the first baffle 400 rotates, the second end is movable in the direction of approaching or moving away from the axis of the first air outlet.

[0041] By using the air outlet assembly 10 disclosed in the present application, the air supply distance and the strength of the wind feeling can be adjusted by 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 strength of the wind feeling can be adjusted steplessly, so that the individualized needs of users in different use scenarios can be met.

[0042] When the plurality of first baffles 400 are combined into a conical barrel, there are gaps between the two adjacent first baffles 400. When the plurality of first baffles 400 are rotated to the second position, there is a larger gap between the two adjacent first baffles 400. This will affect the air outlet effect of the air outlet assembly 10 to some extent. Therefore, the air outlet assembly 10 is further provided with a plurality of second baffles 500 to shield the gaps between the plurality of first baffles 400.

[0043] Specifically, the air outlet assembly 10 is provided with two rows of baffles, i.e., a plurality of first baffles 400 in the inner row and a plurality of second baffles 500 in the outer row. The plurality of second baffles 500 are also distributed along the circumference of the first air outlet and each of the second baffles 500 is rotatably connected to the bottom plate 11, and the second end of each of the second baffles 500 can move in the direction of approaching or moving away from the axis of the air outlet.

[0044] When the plurality of first baffles 400 move inward to the first position, a first conical cylinder is formed, and when the plurality of second baffles 500 move inward to the first position, a second conical cylinder is formed, which is located in the outer row of the first conical cylinder. At this time, each of the second baffles 500 blocks the joint seam between the adjacent two first baffles 400. With such a setting form, air leakage at the joint position of the adjacent two first baffles 400 can be further avoided.

[0045] It should be noted that if only the cross section of the air outlet is reduced, the flow rate of 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, and the air supply distance is short. While using the air outlet assembly 10 provided by the embodiment of the present disclosure, under the condition that the plurality of first baffles 400 are gathered, each of the first baffles 400 plays a role of guiding flow, and the air can form a laminar flow under the wall effect of the first baffles 400, and the energy loss is small during movement, so that it can be blown to a farther position.

[0046] When the plurality of first baffles 400 move outward to the second position, they are enclosed in a cylindrical shape, and there is a gap between the adjacent two first baffles 400. When the plurality of second baffles 500 move outward to the second position, they are enclosed in a cylindrical shape, and each of the second baffles 500 is used to block the gap between the adjacent two first baffles 400. In this way, the first baffles 400 and the second baffles 500 are enclosed in 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 located at the second position can be improved.

[0047] When the plurality of first baffles 400 are located between the first position and the second position, the projection of the second end of the first baffle 400 on the plane where the first air outlet is located is located within the first air outlet, and the second end of the first baffle 400 plays a role of disturbing flow. At this time, the projection of the second end of the second baffle 500 on the plane where the first air outlet is located is also located within the first air outlet, and the second end of the second baffle 500 also plays a role of disturbing flow. In this way, the effect of air supply by disturbing flow with a sharp wedge of the air outlet assembly 10 can be further improved.

[0048] Optionally, when the driving ring 200 rotates in the first direction, the plurality of first baffles 400 and the plurality of second baffles 500 rotate inward, and the plurality of first baffles 400 move ahead 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 rotate outward, and the plurality of second baffles 500 move ahead of the plurality of first baffles 400.

[0049] When the driving ring 200 rotates in the first direction, the plurality of first baffles 400 and the plurality of second baffles 500 rotate inward, and the plurality of first baffles 400 move ahead 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. 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 baffles 400 and the second baffles 500, and then is blown out through the air guiding gap between the adjacent two second baffles 500. The turbulence of the plurality of first baffles 400 and the turbulence 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 baffles 400 and then is blown out after being disturbed by the second baffles 500. With 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-piercing turbulence function.

[0050] Similarly, when the driving ring 200 rotates in the second direction, the plurality of first baffles 400 and the plurality of second baffles 500 rotate outward, and the plurality of second baffles 500 move ahead of the plurality of first baffles 400. When the plurality of first baffles 400 and the plurality of second baffles 500 rotate 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-piercing turbulence function.

[0051] With such a setting form, the plurality of first baffles 400 and the plurality of second baffles 500 have a certain time difference in movement, so that a wind dispersing layer can be formed between the plurality of first baffles 400 and the plurality of second baffles 500, and the plurality of first baffles 400 and the plurality of second baffles 500 can better cooperate to realize the sharp-piercing turbulence function.

[0052] The outer ring of the fixed ring 100 is outwardly convex to form an annular step 180, a plurality of second pivot portions 130 are arranged above the annular step 180, and a plurality of first pivot portions 110 are arranged on the inner ring of the fixed ring 100. The outer ring of the fixed ring 100 is used to connect a plurality of second baffles 500, and the inner ring is used to connect a plurality of first baffles 400. When the plurality of first baffles 400 are spliced, gaps are prone to occur near the fixed ring 100, and the gaps include gaps between adjacent two first baffles 400 and gaps between the first baffles 400 and the fixed ring 100. Therefore, the fixed ring 100 is provided with the annular step 180, the outer ring of the fixed ring 100 is higher than the inner ring of the fixed ring 100, that is, a plurality of first connecting members 120 are arranged below the step, and a plurality of second connecting members are arranged above the step. The gaps of the plurality of first baffles 400 near the fixed 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, thereby improving the air outlet effect of the air outlet assembly 10. In addition, the pivot position of the first baffle 400 is below the step and the pivot 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 can reduce the distance between the first baffle 400 and the second baffle 500, thereby improving the air-tightness of the air outlet assembly 10.

[0053] Optionally, the fixed ring 100 is provided with a plurality of first pivot portions 110 and a plurality of second pivot portions 130 along the circumference of the first air outlet, the plurality of second pivot portions 130 are located outside the plurality of first pivot portions 110, the plurality of first baffles 400 are connected to the fixed ring 100 one by one through the plurality of first pivot portions 110, and the plurality of second baffles 500 are connected to the fixed ring 100 one by one through the plurality of second pivot portions 130; the air outlet assembly 10 further comprises a driving ring 200 coaxial with the fixed ring 100 and rotatable relative to the fixed ring 100, the driving ring 200 is provided with a plurality of first driving portions 210 and a plurality of second driving portions 220, each of the plurality of first baffles 400 is provided with a first driving cooperation portion 420, each of the plurality of second baffles 500 is provided with a second driving cooperation portion 520, the plurality of first driving portions 210 correspondingly cooperate with the plurality of first driving cooperation portions 420, and the plurality of second driving portions 220 correspondingly cooperate with the plurality of second driving cooperation portions 520, the driving ring 200 drives the second ends of the plurality of first baffles 400 and the second ends of the plurality of second baffles 500 to move along the axis of the first air outlet in the direction of approaching or moving away from the first air outlet when the driving ring 200 rotates.

[0054] In order to realize the fixation and driving of the plurality of first baffles 400 and the plurality of second baffles 500, the chassis 11 comprises a fixing ring 100 and a driving ring 200. The fixing ring 100 is used to provide mounting positions for the plurality of first baffles 400 and the plurality of second baffles 500, that is, the plurality of first baffles 400 are rotatably connected to the fixing ring 100, and the plurality of second baffles 500 are rotatably connected to the fixing ring 100. The driving ring 200 is used to drive the plurality of first baffles 400 and the plurality of second baffles 500 to move synchronously to the first position or the second position or a position between the first position and the second position.

[0055] One side of the fixing ring 100 is provided with a plurality of first pivot portions 110, the plurality of first pivot portions 110 correspond to the plurality of first baffles 400 one by one, and the first baffles 400 are rotatably connected to the fixing 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 to realize the rotating connection of the first baffle 400. In another example, the first pivot portion 110 is a rotating shaft 430, and the first baffle 400 is provided with a shaft sleeve, the shaft sleeve cooperates with the rotating shaft 430 to realize the rotating connection of the first baffle 400.

[0056] One side of the driving ring 200 is provided with a plurality of second pivot portions 130, and the second pivot portions 130 are located outside the first pivot portions 110. The plurality of second pivot portions 130 correspond to the plurality of second baffles 500 one by one, and the second baffles 500 are rotatably connected to the fixing ring 100 through the second pivot portions 130. Exemplarily, the second pivot portion 130 is a shaft sleeve, the first end of the second baffle 500 is provided with a rotating shaft 430, and the rotating shaft 430 cooperates with the shaft sleeve to realize the rotating connection of the second baffle 500.

[0057] The driving ring 200 is arranged in parallel with the fixing ring 100, and the driving ring 200 can make plane rotation relative to the fixing ring 100. The driving ring 200 is provided with a plurality of first driving portions 210, each first baffle 400 is provided with a first driving cooperation portion 420, and the plurality of first driving portions 210 correspond to the plurality of first driving portions 210 one by one. The driving ring 200 is also provided with a plurality of second driving portions 220, each second baffle 500 is provided with a second driving cooperation portion 520, and the plurality of second driving portions 220 correspond to the plurality of second driving cooperation portions 520 one by one. When the driving ring 200 rotates, the first driving portion 210 makes circular motion along the plane where the driving ring 200 is located, drives the first driving cooperation portion 420 to move, thereby driving the first baffle 400 to rotate around the first pivot portion 110; the second driving portion 220 makes circular motion along the plane where the driving ring 200 is located, drives the second driving cooperation portion 520 to move, thereby driving the second baffle 500 to rotate around the second pivot portion 130.

[0058] The chassis 11 comprises a fixing ring 100, through which the plurality of first baffles 400 and the plurality of second baffles 500 are fixed, facilitating the installation and positioning of the plurality of first baffles 400 and the plurality of second baffles 500; the plurality of first baffles 400 and the plurality of second baffles 500 are simultaneously driven to move by the driving ring 200, the second ends of the plurality of first baffles 400 can be simultaneously moved to the first position or the second position, and the second ends of the plurality of second baffles 500 can be simultaneously moved to the first position or the second position, 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, the driving ring 200 requires less space for movement, which is conducive to reducing the volume of the air outlet assembly 10.

[0059] Optionally, the annular step 180 protrudes beyond the first pivot part 110 in the air outlet direction.

[0060] The side wall of the annular step 180 shields the gap between the plurality of first air outlet assemblies 10 and the fixing ring 100. The height by which the annular step 180 protrudes from the inner ring of the fixing ring 100 is greater than the height by which the first pivot part 110 protrudes from the inner ring of the fixing ring 100, so that the annular step 180 can better prevent air leakage between the plurality of first baffles 400 and the fixing ring 100.

[0061] Optionally, the first driving part 210 comprises a first guide groove 211, 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 comprises 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 approach the axis of the first air outlet.

[0062] 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 and 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. Under the limiting action of the first guide groove 211, the distance between the first driving pin 421 and the axis of the air outlet gradually increases. The first blocking piece 400 takes the rotation axis as the fulcrum, takes the first driving pin 421 as one end of the lever, and takes the second end of the first blocking piece 400 as the other end of the lever. When the distance between the first driving pin 421 and the axis of the air outlet gradually increases, the distance between the second end of the first blocking piece 400 and the axis of the air outlet gradually decreases. 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.

[0063] Optionally, the angle between the first guide groove 211 and the axis of the first air outlet gradually increases from the first end to the second end.

[0064] In the thickness direction of the first guide groove 211 along the axial direction of the first air outlet, the first guide groove 211 has two opposite inner edges, and the angle between the first guide groove 211 and the axis of the first air outlet refers to the angle between the inner edge along the axial direction 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 groove 211 when it rotates. If a larger cooperation allowance is provided between the first guide groove 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 blocking piece 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 blocking piece 400 is located at the second position, the length direction thereof 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 angle between the first guide groove 211 and the air outlet gradually increases from the first end to the second end, and the degree of inclination of the first driving pin 421 in the rotation process of the first blocking piece 400 is adapted to the degree of inclination of the first guide groove 211. In this way, on the one hand, the friction between the first guide groove 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.

With such a setting form, the first driving pin 421 can be matched with the first guide groove 211 of the driving ring 200 without exceeding the driving ring 200, thereby simplifying the structure of the air outlet assembly 10.

[0067] Optionally, the length direction of the first avoiding groove 141 is along the radial direction of the fixing ring 100, and the width is matched with the size 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 mounting ring 300, thereby avoiding the friction between the first guide groove 211 and the first driving pin 421 when the driving ring 200 rotates, so as to drive the first driving pin 421 to rotate along the circumferential direction of the fixing ring 100. In this way, the reliability of the air outlet assembly 10 can be improved.

With such a setting form, the movement of the first driving pin 421 along the circumferential direction of the fixing ring 100 can be further avoided.

[0071] The plurality of first pivot portions 110 are used for connecting the plurality of first blocking pieces 400, and the plurality of second pivot portions 130 are used for connecting the plurality of second blocking pieces 500. The plurality of first blocking pieces 400 and the plurality of second blocking pieces 500 are connected to the fixing ring 100, so as to simplify the structure of the air outlet assembly 10 and reduce the volume of the air outlet assembly 10.

[0073] Optionally, the driving ring 200 is provided with a plurality of second guide slots 221, and the first end of the second baffle 500 is provided with a second driving pin 521, the second driving pin 521 extends into the second guide slot 221, and when the driving ring 200 rotates in two directions, the second baffle 500 also rotates in two directions.

[0074] The first guide slot 211 is used for driving the first baffle 400 to rotate, and the second guide slot 221 is used for driving the second baffle 500 to rotate. The cooperation between the second driving pin 521 and the second guide slot 221 can refer to the cooperation between the first driving pin 421 and the first guide slot 211. With such a setting form, when the driving ring 200 rotates, a plurality of first baffles 400 and a plurality of second baffles 500 are simultaneously driven to rotate, thereby improving the integration degree of the air outlet assembly 10.

[0075] Optionally, the fixing ring 100 is provided with a plurality of second avoiding slots 142, the plurality of second avoiding slots 142 are located outside the plurality of first avoiding slots 141, and the second driving pin 521 extends into the second guide slot 221 through the second avoiding slot 142.

[0076] When the second baffle 500 rotates, the second driving pin 521 also rotates, and the second driving pin 521 extends into the second guide slot 221 of the driving ring 200 through the second avoiding slot 142 of the fixing ring 100. With such a setting form, the second driving pin 521 can be matched with the second guide slot 221 of the driving ring 200 without exceeding the driving ring 200, thereby simplifying the structure of the air outlet assembly 10.

[0078] The third avoiding slot 341 cooperates with the first avoiding slot 141 to limit the movement of the first driving pin 421 along the circumference of the fixing ring 100. In this way, the rotation of the first driving pin 421 can be better limited to the preset rotation plane, and local excessive stress deformation or fracture of the first driving pin 421 can be avoided.

[0079] Optionally, the mounting ring 300 is provided with a plurality of fourth avoiding grooves 342 corresponding to the plurality of second avoiding grooves 142, and the second driving pin 521 extends into the fourth avoiding grooves 342 through the second guide groove 221.

[0080] The fourth avoiding grooves 342 and the second avoiding grooves 142 cooperate to limit the movement of the second driving pin 521 along the circumference of the fixing ring 100. In this way, the rotation of the second driving pin 521 can be better limited to the preset rotation plane, and the local deformation or fracture of the second driving pin 521 due to excessive force can be avoided.

[0082] The mounting ring 300 is used to fix the air outlet assembly 10 at a preset mounting position, such as the air outlet of a cabinet air conditioner. The bottom plate 11 is sequentially provided with the mounting ring 300, the driving ring 200 and the fixing ring 100 in the air outlet direction, and the driving ring 200 is located between the mounting ring 300 and the fixing ring 100. When the driving ring 200 drives the plurality of first baffle plates 400 to rotate, the movement of the driving ring 200 is not easy to interfere with the air outlet assembly 10 or other parts of the air conditioner. The mounting ring 300 and the fixing ring 100 form the driving space, so that the air outlet assembly 10 has a neat appearance.

[0083] Optionally, the mounting ring 300 is provided with a first sliding groove 320; the fixing ring 100 is provided 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 beyond two side surfaces of the driving ring 200 and extend into the first sliding groove 320 and the second sliding groove 160.

[0084] The driving ring 200 rotates in the driving space. 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 provided with a first sliding groove 320, and the fixing ring 100 is provided with a second sliding groove 160 corresponding to the first sliding groove 320. The first sliding groove 320 and the second sliding groove 160 are both 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 from two surfaces 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 conducive 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, the two ends of the sliding column 230 respectively extend into the first sliding groove 320 and the second sliding groove 160, which is conducive 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 during rotation can be improved, which is conducive to the synchronous rotation of the plurality of first baffles 400 driven by the driving ring 200.

[0085] 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 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 first sliding groove 320, 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.

[0086] 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, which affects 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 portions of the sliding column 230. By adopting such a setting form, the first baffles 400 can be accurately moved to the first position or the second position, which improves the accuracy of the movement control of the first baffles 400 by the air outlet assembly 10.

[0088] The rotation of the driving ring 200 is limited by the second sliding groove 160 and the rotation of the driving ring 200 is limited by the first sliding groove 320, which can have the same effect.

[0089] Optionally, one side of the mounting ring 300 facing the fixed ring 100 is provided with a plurality of positioning bosses 330 along the circumference of the first air outlet, and the fixed 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.

[0090] The driving ring 200 rotates between the mounting ring 300 and the fixed ring 100, and a margin is needed between the mounting ring 300 and the fixed ring 100 for the rotation of the driving ring 200. Therefore, the mounting ring 300 is provided with a plurality of positioning bosses 330 along the circumference thereof, and the fixed ring 100 is provided with a plurality of positioning matching parts 170 along the circumference thereof. One side of the positioning boss 330 facing the fixed ring 100 abuts against one side of the positioning matching part 170 facing the mounting ring 300. With such a setting form, it is beneficial to the installation and positioning of the mounting ring 300 and the fixed ring 100 in terms of relative distance and coaxiality.

[0091] Optionally, the driving ring 200 is located in the inner circle of the plurality of positioning bosses 330.

[0092] If the positioning boss 330 penetrates the driving ring 200, the driving ring 200 needs to be provided with a corresponding avoiding groove, which will affect the structural strength of the driving ring 200. Therefore, the driving ring 200 is located in the inner circle of the plurality of positioning bosses 330. In this way, the positioning boss 330 and the positioning matching part 170 will not interfere with the rotation of the driving ring 200, and the driving ring 200 does not need to be provided with an avoiding groove structure with high structural strength.

[0093] Optionally, the top of the positioning boss 330 is provided with a positioning pin 331, and the positioning matching part 170 is provided with a positioning hole 171 corresponding to the positioning pin 331, and the positioning pin 331 is inserted into the positioning hole 171.

[0094] The top of the positioning boss 330 is configured with a positioning pin 331. The side of the positioning boss 330 facing the fixing ring 100 is provided with a positioning hole 171, and the positioning pin 331 is inserted into the positioning hole 171, which facilitates the accurate installation and positioning between the mounting ring 300 and the fixing ring 100.

[0096] With such a setting form, the fixing ring 100 and the mounting ring 300 are injection molded. In addition, the positioning matching part 170 and the positioning boss 330 serve as a reinforcing rib, which can improve the structural strength of the first buckling and the second buckling part 150.

[0097] Optionally, when the first baffle 400 and the second baffle 500 rotate to the second position, the second baffle 500 extends beyond the first baffle 400 in the air outlet direction.

[0098] The height of the second baffle 500 extending from the fixing ring 100 is greater than the height of the first baffle 400 extending from the fixing ring 100. When the plurality of first baffles 400 are gathered inward, the length of the second baffle 500 is longer, which can better block the gap between the first baffles 400. When the plurality of first baffles 400 are located between the first position and the second position for sharp-piercing flow interference air supply, the length of the second baffle 500 is longer, and the first baffle 400 intersects and overlaps the plane where the first air outlet is located, so that the plurality of second baffles 500 and the plurality of first baffles 400 can better jointly play a sharp-piercing flow interference role. When the plurality of first baffles 400 are located at the second position, the plurality of second baffles 500 are longer than the plurality of first baffles 400. In this way, the change of the flow passage cross section when air is blown out by the air outlet assembly 10 can be certain. Excessive, avoiding the formation of strong turbulence at the air outlet, which can improve the air outlet effect of the air outlet assembly 10.

[0099] Optionally, the first baffle 400 includes 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] The plurality of first baffles 400 can be combined into a conical cylinder, and the width of the second end of each first baffle 400 is smaller than the width of the first end. Specifically, the first baffle 400 includes a plate body 410 as the main body of the first baffle 400, which plays a role in enclosing and guiding air when the plurality of first baffles 400 are combined. The width of the plate body 410 gradually decreases from the first end to the second end, so that it can be combined into a sealed conical cylinder when gathered. The rotating shaft is arranged at the first end of the plate body 410, and the rotating shaft cooperates with the first pivot part 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 is connected to the first end of the plate body 410 or the rotating shaft at one end and extends into the first guide groove 211 at the other end. With such an arrangement, the driving ring 200 can drive the first baffle 400 to rotate.

[0101] Optionally, the inward side of the first baffle 400 is configured with an air guiding protrusion 413, and two adjacent air guiding protrusions 413 form an air guiding groove corresponding to the wedge-shaped protrusion 440.

[0102] Optionally, the plate body 410 includes an air blocking part 411 and a mounting part 412, wherein the width of the air blocking part 411 gradually decreases from the first end to the second end; the mounting part 412 is connected to the first end of the baffle, and the mounting part 412 and the air blocking part 411 have a first included angle therebetween.

[0103] The plate body 410 includes an air blocking part 411 and a mounting part 412, and the air blocking parts 411 of the plurality of first baffles 400 are combined to form a conical barrel, and the mounting part 412 is used to fix the first baffle 400 to the bottom disc 11.

[0104] The width of the air blocking part 411 gradually decreases from the first end to the second end, which is conducive to the combination of the air blocking parts 411 of the plurality of first baffles 400.

[0105] In the case where the plurality of first baffles 400 enclose to form a conical barrel, in the length direction, the air blocking part 411 is generally along the axial direction of the first air outlet, and the mounting part 412 is generally along the radial direction of the first air outlet. The mounting part 412 and the air blocking part 411 have a first included angle therebetween, so that the mounting part 412 can be attached to the bottom disc 11. The mounting part 412 is attached to the bottom disc 11, and the fixing of the first baffle 400 can be achieved without opening a hole in the bottom disc 11, so that air leakage of the air outlet assembly 10 can be avoided; the mounting part 412 is attached to the bottom disc 11, and the contact area therebetween is large, so that the fixing effect of the bottom disc 11 on the first baffle 400 can be improved.

[0106] Optionally, the first included angle is greater than 90 degrees.

[0107] In the case that 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 that the mounting portion 412 is attached to the bottom plate 11, the second end of the wind blocking portion 411 is inwardly converged, so that the plurality of first baffles 400 are spliced into a conical barrel. By adopting such a setting form, the fixing effect of the bottom plate 11 on the first bottom plate 11 can be further improved.

[0108] Optionally, the middle portion of the wind blocking portion 411 is convex to the first air outlet.

[0109] The middle portion 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 rate is more in the portion close to the first end and less in the portion close to the second end. The turbulence formed by throttling and acceleration of air is more in the front section of the conical barrel, and the change of speed is less in the rear section of the conical barrel. The wall effect at the rear end of the conical barrel rectifies the air 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. By adopting such a setting form, the air supply distance of the air outlet assembly 10 can be further improved.

[0110] Optionally, the inner surface of the plate body 410 is provided with a wind guide protrusion 413 extending along the length direction of the first baffle 400.

[0111] The wind guide protrusion 413 on the inner surface of the plate body 410 is wedge-shaped or triangular, and the 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, two adjacent wind guide protrusions 413 form a wind guide groove. The portion of the air flowing in the conical barrel close to the inner wall of the conical barrel is divided into multiple streams flowing along multiple wind guide grooves by the wind guide protrusion 413. Under the guidance of the multiple first wind 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 conical barrel on the flow of other parts of the air can be reduced, the kinetic energy loss of the air in the conical barrel can be reduced, and thus the air supply distance of the air outlet assembly 10 can be improved.

[0112] Optionally, the plate body 410 is provided with two wind guide protrusions 413, and a wind guide groove is formed between the two adjacent wind guide protrusions 413.

[0113] The plate body 410 is provided with two wind guide protrusions 413, and more wind guide grooves can be formed on the inner wall of the conical barrel. In this way, the kinetic energy loss of the air in the conical barrel can be further reduced, and thus the air supply distance of the air outlet assembly 10 can be improved.

[0114] Optionally, the two air guide protrusions 413 are arranged close to the two side edges of the plate body 410, and one side edge of the air guide protrusions 413 serves as the first joint part 414.

[0115] The two air guide protrusions 413 of the plate body 410 are arranged 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 baffle sheets 400 are spliced, the first baffle sheet 400 is not easily deformed, and the first baffle sheet 400 is not easily vibrated when the air flows through the conical cylinder.

[0116] After the air guide protrusions 413 are arranged 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 relatively thick at the side edges. The thickened side edges serve as the first joint part 414. When the plurality of first baffle sheets 400 are spliced, in the first aspect, the first baffle sheet 400 is not easily deformed due to the mutual contact; in the second aspect, the side edges of the plate body 410 are thick, and the two adjacent first baffle sheets 400 are not easily misaligned or have flash joints when spliced.

[0117] Optionally, the outer side of the plate body 410 is provided with a wedge-shaped protrusion 440.

[0118] The outer side of the plate body 410 is provided with a wedge-shaped protrusion 440. In a cross section of the first baffle sheet 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 a plurality of bending structures, which can further improve the structural strength of the plate body 410.

[0119] 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.

[0120] 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 in the air guide groove has a gradually expanding cross section. 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, and the kinetic energy loss generated by the contact between the vortex and the air in other positions is reduced. The wedge-shaped protrusion 440 corresponds to the air guide groove, so that the thickness of the plate body 410 is relatively uniform on the entire plane. By adopting this setting form, the structural strength of the first baffle sheet 400 is improved while the weight of the first baffle sheet 400 is reduced, and the cost of the air outlet assembly 10 is reduced.

[0151] The air conditioner comprises a shell 710 and a fan case 720. The shell 710 is configured with a receiving space, and the fan case 720 is arranged in the receiving space. The independently arranged fan case 720 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 case 720 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 case 720, 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 case 720 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 disturbing flow, so that the sharp wedge flow disturbance air supply is realized. In terms of structure, the fan case 720 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 baffle 400 or the second baffle 500 of the air outlet assembly 10 is neither in the fan case 720 nor outside the shell 710, and the movement of each moving part of the air outlet assembly 10 is not easily interfered.

[0152] 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 cross section of the air outlet air duct is reduced, so that the air supply distance is increased and the wind feeling is enhanced; the cross section of the air outlet air duct is increased, so that the air supply distance is reduced and the wind feeling is weakened. 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.

In the second box 722, there is more turbulence under the stirring of the fan blades. After the air flows through the first box 721 from the second box 722, the first box 721 plays a rectifying effect, and the laminar flow in the air increases, and after blowing out from the third air outlet, the air can be blown to a farther distance. 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.

[0156] Optionally, the bottom end of the first box 721 is opposite to the top end of the second box 722, and the third air outlet and the air inlet are arranged on different sides of the fan box 720.
