[0065] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the applicability of other processes and / or the use of other materials.

[0067] The air conditioner 100 according to the embodiments of the present invention will be described below with reference to the drawings.

[0068] The air conditioner 100 according to the embodiments of the present invention, as Figure 1 and Figure 2 shown, the air conditioner 100 includes: an air conditioner main body 10 and a wind deflector 20. The air conditioner main body 10 has an air outlet 11. The wind deflector 20 is rotatably provided at the air outlet 11. At least one end on the rotation axis of the wind deflector 20 is detachably engaged with the air conditioner main body 10 through a quick-release unit 30. The quick-release unit 30 includes a rotating shaft 31 and a quick-release assembly 32 that are detachably engaged.

[0069] The air deflector 20 can rotate to adjust the air supply direction of the air outlet 11 of the air conditioner 100, improve the air supply range of the air conditioner 100, and enable the air conditioner 100 to supply air to a specific area. The air deflector 20 is arranged at the air outlet 11, and a large amount of dust will accumulate during long-term use. After the air conditioner 100 is used for a period of time, the air deflector 20 needs to be removed from the air conditioner body 10 for cleaning and maintenance operations. However, in the related art, the disassembly and reassembly of the air deflector are both difficult, resulting in difficult cleaning and maintenance operations of the air deflector.

[0070] In the air conditioner 100 according to the embodiment of the present invention, the air deflector 20 is detachably assembled with the air conditioner body 10 through the quick-release unit 30, which can reduce the operation difficulty of disassembling and assembling the air deflector 20 and the air conditioner body 10, improve the disassembly and assembly efficiency of the air deflector 20 and the air conditioner body 10, facilitate the user to clean and maintain the air deflector 20, and is beneficial to improving the working reliability of the air deflector 20. Optionally, one end on the rotation axis of the air deflector 20 is detachably assembled with the air conditioner body 10 through the quick-release unit 30; alternatively, both ends on the rotation axis of the air deflector 20 are detachably assembled with the air conditioner body 10 through the quick-release unit 30.

[0071] One of the quick-release component 32 and the rotating shaft 31 is arranged on the air deflector 20, and the other of the quick-release component 32 and the rotating shaft 31 is arranged on the air conditioner body 10. The quick-release component 32 and the rotating shaft 31 are rotatably matched, so that the air deflector 20 and the air conditioner body 10 can rotate relative to each other and can be quickly disassembled and assembled. The cooperation selection of the quick-release component 32 and the rotating shaft 31 with the air deflector 20 and the air conditioner body 10 can be selected according to actual needs.

[0072] The structure of the quick-release component 32 can realize the quick disassembly and assembly of the quick-release component 32 and the rotating shaft 31. As Figures 3 - 5 shown, the quick-release component 32 includes: a mating shaft 4 and a sliding sleeve 5. The mating shaft 4 has a mating cavity 41. The mating cavity 41 penetrates the axial end face of the mating shaft 4 to form an end opening 411, and penetrates the outer peripheral surface of the mating shaft 4 to form a side opening 412. As Figure 6 shown, the rotating shaft 31 is adapted to enter and exit the mating cavity 41 through the side opening 412, and the end opening 411 is used to avoid the rotating shaft 31.

[0073] As Figure 6 shown, the axial direction of the rotating shaft 31 is the same as the axial direction of the mating shaft 4. The mating cavity 41 penetrates the axial end face and the outer peripheral surface of the mating shaft 4. The rotating shaft 31 can be directly inserted into the mating cavity 41 along the opening direction of the side opening 412 to be connected with the mating shaft 4; the rotating shaft 31 is directly moved out of the mating cavity 41 along the opening direction of the side opening 412, and the connection between the rotating shaft 31 and the mating shaft 4 can be released.

[0074] One end of the rotating shaft 31 is connected to the air deflector 20 or the air conditioner body 10. The other end of the rotating shaft 31 can then enter and exit the fitting cavity 41 through the side opening 412, while the end opening 411 can avoid the movement of the rotating shaft 31.

[0075] In the related art, in the connection method where the rotating shaft is axially matched with the mating shaft, the air deflector needs to move relative to the air conditioner body along the length direction of the air outlet. The space in the length direction of the air outlet is limited, the disassembly and assembly operation space of the air deflector is restricted, and the disassembly and assembly operation of the air deflector is difficult, which is not conducive to the cleaning and maintenance of the air deflector.

[0076] For the air deflector 20 of the embodiment of the present utility model, the air deflector 20 rotates relative to the air outlet 11 with the axis of the rotating shaft 31 as the rotation axis. The length direction of the air deflector 20 is consistent with the axial direction of the rotating shaft 31. In the embodiment of the present utility model, the rotating shaft 31 is inserted into the side opening 412 along a direction perpendicular to or substantially perpendicular to the axis of the rotating shaft 31, that is, the air deflector 20 directly moves relative to the air conditioner body 10 in the inner and outer directions of the air outlet 11, and the disassembly and assembly of the air deflector 20 and the air conditioner body 10 can be completed. The space in the air outlet direction of the air outlet 11 is the external space of the air conditioner body 10, and the space available for the disassembly and assembly operation of the air deflector 20 is large, which can reduce the operation difficulty of the disassembly and assembly of the air deflector 20 and the air conditioner body 10, improve the disassembly and assembly efficiency of the air deflector 20 and the air conditioner body 10, and facilitate the user to clean and maintain the air deflector 20.

[0077] It should be noted that the air deflector 20 is relatively long. One end on the rotation axis of the air deflector 20 is detachably fitted with the air conditioner body 10 through the quick-release unit 30. When the other end of the air deflector 20 is still assembled on the air conditioner body 10, first disassemble one end of the air deflector 20 from the air conditioner body 10 through the quick-release unit 30. The movement of the rotating shaft cannot move in a radial straight line direction, but should move and disassemble along a direction substantially perpendicular to the axis of the rotating shaft 31, and the movement trajectory is an arc. The same is true during assembly. When the other end of the air deflector 20 has been assembled, one end of the air deflector 20 needs to be assembled along a direction substantially perpendicular to the axis of the rotating shaft 31. When both ends of the air deflector 20 are detachably fitted with the air conditioner body 10 through the quick-release unit 30 and the two ends of the air deflector 20 are simultaneously loaded and unloaded with the air conditioner body 10, the air deflector 20 can be directly driven to move along a direction perpendicular to the axis of the rotating shaft 31, and the movement trajectory is a straight line.

[0078] Such as Figure 4 and Figure 5 As shown, the sliding sleeve 5 is sleeved outside the mating shaft 4 and can move between a locking position that blocks the side opening 412 and an unlocking position that opens the side opening 412.

[0079] When the sliding sleeve 5 is in the locked position, the outer sleeve of the sliding sleeve 5 is at the side opening 412 of the mating shaft 4, and the rotating shaft 31 can be limited within the mating cavity 41, thereby enhancing the connection stability between the rotating shaft 31 and the mating shaft 4. When the sliding sleeve 5 is in the unlocked position, the sliding sleeve 5 opens the side opening 412, and the rotating shaft 31 can directly enter and exit the mating cavity 41 through the side opening 412, realizing the disassembly and assembly of the air deflector 20 and the air conditioner body 10.

[0080] For the air conditioner 100 according to the embodiment of the present invention, by providing the quick-release assembly 32, the mating cavity 41 cooperating with the rotating shaft 31 forms a side opening 412 on the outer peripheral surface, and the rotating shaft 31 can directly move in a direction perpendicular to or substantially perpendicular to the axis of the rotating shaft 31 and be directly inserted into the mating cavity 41, or be removed from the mating cavity 41 to realize the connection and separation between the rotating shaft 31 and the mating shaft 4. The air deflector 20 with its length direction consistent with the axial direction of the rotating shaft 31 can directly move relative to the air conditioner body 10 in the inner and outer directions of the air outlet 11, and thus the disassembly and assembly of the air deflector 20 and the air conditioner body 10 can be completed. The space available for the disassembly and assembly operation of the air deflector 20 is relatively large, which can reduce the operation difficulty of the disassembly and assembly of the air deflector 20 and the air conditioner body 10, improve the disassembly and assembly efficiency of the air deflector 20 and the air conditioner body 10, facilitate the user to clean and maintain the air deflector 20, and is beneficial to improving the working reliability of the air deflector 20.

[0081] Next, with reference to Figure 6 and Figure 8 briefly describe the process of disassembling and assembling the rotating shaft 31 and the quick-release assembly 32.

[0082] First, as shown in Figure 6 , when the sliding sleeve 5 is in the unlocked position, the side opening 412 is opened. Subsequently, as shown in Figure 7 , the rotating shaft 31 is directly inserted into the mating cavity 41 in a direction perpendicular to or substantially perpendicular to the axis of the rotating shaft 31. Finally, as shown in Figure 8 , the sliding sleeve 5 is moved to the locked position, and the assembly of the rotating shaft 31 and the quick-release assembly 32 can be completed.

[0083] The disassembly process of the rotating shaft 31 and the quick-release assembly 32 is opposite to the assembly process. First, as shown in Figures 8 to 7 , the sliding sleeve 5 is moved from the locked position to the unlocked position to open the side opening 412. Subsequently, as shown in Figure 6 , the rotating shaft 31 is moved in a direction perpendicular to or substantially perpendicular to the axis of the rotating shaft 31, and the rotating shaft 31 is removed from the mating cavity 41, and the separation of the rotating shaft 31 and the quick-release assembly 32 can be completed.

[0084] In some embodiments of the present invention, as shown in Figure 9 , the mating cavity 41 is configured in an open form facing the direction of the side opening 412 to be suitable for guiding the rotating shaft 31 to be inserted into the mating cavity 41 from the side opening 412.

[0085] As shown Figure 9 in the figure, the dashed line n is a straight line in the radial direction of the mating shaft 4 in the direction towards the side opening 412, and the dashed line m is a straight line in the extending direction of the side wall of the mating cavity 41. The dashed line n and the dashed line m intersect, and the dashed line n deflects outward compared to the dashed line m.

[0086] By configuring the mating cavity 41 in an open form towards the side opening 412, the cross-sectional area of the mating cavity 41 gradually increases in the direction towards the side opening 412, which can play a guiding role in the assembly of the mating shaft 4 and improve the assembly efficiency of the rotating shaft 31 and the mating shaft 4.

[0087] In some embodiments of the present invention, as shown Figure 1 、 Figure 2 and Figure 8 in the figure, the rotation axis of the air deflector 20 extends in the up and down direction. The upper end of the air deflector 20 is provided with a rotating shaft 31, and a quick-release assembly 32 is correspondingly arranged at the upper end of the air deflector 20.

[0088] The rotating shaft 31 is arranged on the air deflector 20, and the quick-release assembly 32 is arranged on the air conditioner body 10. The rotation axis line of the air deflector 20 extends in the up and down direction. By arranging the rotating shaft 31 at the upper end of the air deflector 20 and cooperating with the quick-release assembly 32, compared with the design method of arranging the rotating shaft at the lower end of the air deflector 20, it is not necessary to hold up the air deflector 20 for disassembly and assembly. For the disassembly and assembly of the air deflector 20 in the embodiment of the present invention, the influence of the gravity of the air deflector 20 is small, and the difficulty of disassembly and assembly operations can be further reduced; and the quick-release assembly 32 is arranged at the upper end of the air deflector 20, and the user can operate with a straight body during operation. Compared with the design method of arranging the rotating shaft at the lower end of the air deflector 20, it is not necessary to squat down for operation, which is convenient for the user to clean and maintain the air deflector 20.

[0089] In some embodiments of the present invention, as shown Figure 6 in the figure, the upper end of the rotating shaft 31 at the upper end of the air deflector 20 is connected to the air deflector 20 and the lower end extends downward. The mating cavity 41 penetrates the upper end surface of the mating shaft 4, and the end opening 411 of the mating shaft 4 at the upper end surface can avoid the movement of the rotating shaft 31.

[0090] As shown Figure 7 and Figure 8As shown, the locking position is higher than the unlocking position. The sliding sleeve 5 is sleeved outside the mating shaft 4. The axial length of the mating shaft 4 is relatively long, and a side opening 412 is formed on the outer peripheral surface at the upper end of the mating shaft 4. When the sliding sleeve 5 moves upward along the axis of the mating shaft 4 to the locking position, the side opening 412 is blocked. When the sliding sleeve 5 moves downward along the axis of the mating shaft 4 to the unlocking position, the side opening 412 is opened. The sliding sleeve 5 can be switched in position by moving up and down, and the control of the sliding sleeve 5 is relatively simple, which can reduce the operation difficulty of disassembling and assembling the rotating shaft 31 and the quick-release component 32.

[0091] In some embodiments of the present invention, as Figure 10 shown, one end of the mating cavity 41 away from the end opening 411 is the inner end 41a of the cavity. The mating cavity 41 is formed in a form of narrowing from the inner end 41a to the end opening 411. As Figure 11 shown, the cross-section of the rotating shaft 31 matches that of the mating cavity 41 to limit the axial movement of the rotating shaft 31 relative to the mating cavity 41 along the direction from the inner end 41a to the end opening 411.

[0092] As Figure 8 shown, when the sliding sleeve 5 is in the locking position, the sliding sleeve 5 is wrapped outside the mating shaft 4 and also outside the rotating shaft 31. The quick-release component 32 limits the rotating shaft 31 in multiple directions. By setting the mating cavity 41 in a form of narrowing from the inner end 41a to the end opening 411, the mating shaft 4 can limit the upward movement of the rotating shaft 31 and restrict the upward axial movement of the rotating shaft 31, further improving the cooperation stability between the rotating shaft 31 and the quick-release component 32 and enhancing the rotational movement reliability of the air deflector 20.

[0093] In some embodiments of the present invention, as Figure 10 shown, the mating shaft 4 has a first limiting portion 42, and the sliding sleeve 5 has a second limiting portion 51. When the sliding sleeve 5 is in the locking position, the second limiting portion 51 is in limiting cooperation with the first limiting portion 42 to prevent the sliding sleeve 5 from moving axially along the mating shaft 4.

[0094] As Figure 10 shown, the sliding sleeve 5 moves axially to switch between the locking position and the unlocking position. By setting the first limiting portion 42 and the second limiting portion 51, the sliding sleeve 5 can be stably limited in the locking position, thereby improving the connection stability between the rotating shaft 31 and the mating shaft 4 and enhancing the working reliability of the air deflector 20.

[0095] In some embodiments of the present invention, as Figure 3 and Figure 10 shown, the first limiting portion 42 is a card slot 421 provided on the outer peripheral surface of the mating shaft 4, and the second limiting portion 51 is located at the axial end of the sliding sleeve 5 and is a buckle 511 that cooperates with the card slot 421.

[0096] When the buckle 511 and the clamping groove 421 are in clamping fit, the sliding sleeve 5 is limited in the locking position. When the clamping fit between the buckle 511 and the clamping groove 421 is released, the sliding sleeve 5 can move axially along the mating shaft 4. The sliding sleeve 5 and the mating shaft 4 are mutually cooperated through the clamping of the buckle 511 and the clamping groove 421. When the sliding sleeve 5 moves to the locking position, the clamping can be automatically completed, which is convenient for the operation of fixedly connecting the rotating shaft 31 and the mating shaft 4; and the operation of releasing the clamping of the buckle 511 and the clamping groove 421 is also relatively simple, which can simplify the disassembly and assembly operations of the air deflector 20 and the air conditioner body 10.

[0097] In some embodiments of the present invention, as Figure 3 and Figure 10 shown, on the outer peripheral surface of the mating shaft 4, there are provided a first annular rib 43 and a second annular rib 44 surrounding the mating shaft 4. The first annular rib 43 and the second annular rib 44 are spaced apart axially along the mating shaft 4 to form a clamping groove 421 between the first annular rib 43 and the second annular rib 44.

[0098] As Figure 3 shown, the second annular rib 44 is arranged closer to the axial end face where the end opening 411 is located compared with the first annular rib 43. The first annular rib 43 and the second annular rib 44 protrude from the outer peripheral surface of the mating shaft 4. A clamping groove 421 is formed between the first annular rib 43 and the second annular rib 44. The first annular rib 43 and the second annular rib 44 are arranged in parallel and spaced apart, so that the width of the clamping groove 421 is equal. Compared with arranging an inwardly concave clamping groove on the outer peripheral surface of the mating shaft, by arranging the protruding first annular rib 43 and second annular rib 44 on the outer peripheral surface of the mating shaft 4, the limitation of the buckle 511 can be improved, and the stability of the sliding sleeve 5 in the locking position can be enhanced.

[0099] Among them, the slope of the wall surface of the second annular rib 44 forming the clamping groove 421 is relatively large, which can prevent the sliding sleeve 5 from continuing to move towards the axial end face where the end opening 411 is located, and enhance the stability of the sliding sleeve 5 in the locking position.

[0100] In some embodiments of the present invention, as Figure 12 shown, the sliding sleeve 5 includes an end ring portion 52 and elastic arms 531 arranged axially in sequence. The elastic arms 531 are multiple and are spaced apart circumferentially along the end ring portion 52. A buckle 511 is arranged at one end of the elastic arm 531 away from the end ring portion 52.

[0101] The elastic arms 531 can generate elastic deformation. When the elastic arms 531 are in the undeformed state, the buckle 511 is in clearance fit with the outer peripheral surface of the mating shaft 4, so as to facilitate the axial movement of the sliding sleeve 5 along the mating shaft 4. The sliding sleeve 5 moves smoothly, which can reduce the wear of the buckle 511 and extend the working life of the sliding sleeve 5.

[0102] When the sliding sleeve 5 moves towards the locking position, the elastic arm 531 deforms towards the outside. When the buckle 511 passes over the first annular rib 43 and enters the card slot 421, the elastic arm 531 returns to its original state, and the buckle 511 is engaged with the card slot 421 in a snap-fit manner. When the sliding sleeve 5 moves towards the unlocking position, the elastic arm 531 deforms, the buckle 511 passes over the first annular rib 43 and disengages from the card slot 421, the elastic arm 531 returns to its original state, and the sliding sleeve 5 can move axially along the mating shaft 4.

[0103] By providing the deformable elastic arm 531, while the sliding sleeve 5 moves axially along the mating shaft 4, the elastic arm 531 is driven to deform by the first annular rib 43 and smoothly enters the card slot 421, making the assembly of the sliding sleeve 5 more labor-saving. And it is also convenient for the buckle 511 to disengage from the card slot 421, facilitating the sliding sleeve 5 to release the limitation on the rotating shaft 31 and the mating shaft 4.

[0104] In some embodiments of the present utility model, as Figure 13 shown, the wall surface of the axial end face where the far-end opening 411 of the first annular rib 43 is located is the first guiding surface 431, and the first guiding surface 431 extends obliquely outward in the direction from the first annular rib 43 to the second annular rib 44; the wall surface of the axial end face where the near-end opening 411 of the first annular rib 43 is located is the second guiding surface 432, and the second guiding surface 432 extends obliquely outward in the direction from the first annular rib 43 to the second annular rib 44.

[0105] The slope of the first guiding surface 431 is smaller than the slope of the second guiding surface 432. As Figure 13 shown, the angle α between the straight line where the first guiding surface 431 is located and the axis is smaller than the angle β between the straight line where the second guiding surface 432 is located and the axis.

[0106] The first annular rib 43 can play a guiding role. When the sliding sleeve 5 moves from the unlocking position to the locking position, the elastic arm 531 deforms along the wall surface of the first annular rib 43, and the buckle 511 can more easily enter the card slot 421 through the first annular rib 43, making the assembly of the sliding sleeve 5 more labor-saving; and the first annular rib 43 can also play a limiting role, making it more difficult for the sliding sleeve 5 to disengage from the card slot 421, and improving the stability of the sliding sleeve 5 when it is in the locking position.

[0107] In some embodiments of the present utility model, the angle α between the straight line where the first guiding surface 431 is located and the axis is less than 45°.

[0108] In some embodiments of the present utility model, as Figure 13 shown, in the axial direction of the mating shaft 4, the slot opening size h1 of the card slot 421 is larger than the root size h2 of the buckle 511.

[0109] When the buckle 511 is engaged in the slot 421, there is a certain gap between the buckle 511 and the inner wall of the slot 421 in the axial direction of the mating shaft 4, which can provide the buckle 511 with an axial displacement along the mating shaft 4, improve the situation where the sliding sleeve 5 escapes from the slot 421 when impacted, and improve the stability of the sliding sleeve 5 when it is in the locked position.

[0110] In some embodiments of the present invention, Figure 3 and Figure 10 As shown, the shaft end of the mating shaft 4 forming the end opening 411 is provided with a third annular rib 45 surrounding the mating shaft 4. When the sliding sleeve 5 is in the locking position, the third annular rib 45 is clearance-fitted or abutt-fitted with the inner rear surface of the sliding sleeve 5.

[0111] By providing the third annular rib 45 with clearance fit or abutment fit with the sliding sleeve 5 , the stability of the sliding sleeve 5 in the locked position can be improved, the shaking of the sliding sleeve 5 can be reduced, and the connection reliability of the rotating shaft 31 and the matching shaft 4 can be improved.

[0112] In some embodiments of the utility model, the mating shaft 4 has a first limiting portion 42, which is located outside the edge of the shaft end face of the side opening 412 away from the end opening 411, and the sliding sleeve 5 has a second limiting portion 51. When the sliding sleeve 5 is in the locked position, the second limiting portion 51 is limitedly matched with the first limiting portion 42. The shaft end face of the sliding sleeve 5 located away from the end opening 411 of the side opening 412 is limitedly matched with the mating shaft 4, and the shaft end face of the sliding sleeve 5 close to the end opening 411 is abutted with the third annular rib 45, and the sliding sleeve 5 stably blocks the side opening 412, reduces the shaking of the sliding sleeve 5, and improves the connection reliability of the rotating shaft 31 and the mating shaft 4.

[0113] In some embodiments of the present invention, Figure 15 and Figure 16 As shown, the matching shaft 4 and the sliding sleeve 5 are matched with each other through a guiding structure, and the guiding structure is used to guide the sliding sleeve 5 to slide relative to the matching shaft 4 along the axial direction of the matching shaft 4 without rotation.

[0114] The guide structure can improve the stability of the movement of the sliding member 5 between the locked position and the unlocked position, and guide the sliding member 5 to move smoothly between the locked position and the unlocked position, which is beneficial to improving the disassembly and assembly efficiency of the rotating shaft 31 and the matching shaft 4.

[0115] The matching shaft 4 and the sliding sleeve 5 can also limit the sliding sleeve 5 through the cooperation of the guide structure. The sliding sleeve 5 moves along the axial direction of the matching shaft 4 to switch between the unlocked position and the locked position. The limiting of the guiding mechanism can limit the rotation of the sliding sleeve 5 relative to the matching shaft 4, thereby improving the situation in which the sliding sleeve 5 fails to open or cover the side opening 412 due to the movement misalignment of the sliding sleeve 5, thereby improving the working stability of the sliding sleeve 5.

[0116] In some embodiments of the present invention, Figure 15 and Figure 16 As shown, the guide structure includes a guide rib 54 and a guide groove 46 for guiding matching. Figure 3 and Figure 14 As shown, the guide groove 46 is formed on the outer peripheral surface of the mating shaft 4 and extends along the axial direction of the mating shaft 4. Figure 12 As shown, the guide rib 54 is protrudingly arranged on the inner circumference of the sliding sleeve 5 .

[0117] The guide rib 54 is movably arranged in the guide groove 46. Through the guiding cooperation between the guide rib 54 and the guide groove 46, the sliding sleeve 5 can be guided to move along the axial direction of the matching shaft 4, and the groove wall of the guide groove 46 limits the guide rib 54, which can limit the axial non-rotational sliding of the sliding sleeve 5 relative to the matching shaft 4.

[0118] In some embodiments of the present invention, Figure 3 and Figure 14 As shown, at least two axial ribs 49 protruding from the outer circumference and extending in the axial direction are formed on the outer circumference of the mating shaft 4 . The two axial ribs 49 are spaced apart along the circumference of the mating shaft 4 , and a guide groove 46 is formed between the two axial ribs 49 .

[0119] In some embodiments of the present invention, Figure 3 and Figure 14 As shown, there are two guide grooves 46 located on both sides of the matching shaft 4 in the diameter direction. Figure 12 and Figure 17 As shown, the number of guide ribs 54 is consistent with the number of guide grooves 46 and is arranged in a one-to-one correspondence.

[0120] There are two guide grooves 46 located on both sides of the mating shaft 4 in the radial direction, and there are two guide ribs 54 arranged one-to-one with the guide grooves 46. The cooperation between the two guide ribs 54 and the two guide grooves 46 can make the sliding member 5 evenly stressed, improve the guiding effect, and improve the reliability of the axial movement of the sliding member 5 along the mating shaft 4. The two guide grooves 46 are arranged on both sides of the diameter direction of the mating shaft 4, and can also limit the sliding member 5, and can improve the shaking of the sliding member 5 relative to the mating shaft 4.

[0121] In addition, the two guide grooves 46 are disposed on both sides of the matching shaft 4 in the diameter direction. The matching between the guide rib 54 and the guide groove 46 is non-directional, which can prevent fooling, facilitate the assembly of the sliding sleeve 5 to the matching shaft 4, and improve the assembly efficiency.

[0122] In some embodiments of the present invention, Figure 3 and Figure 14As shown, one of the guiding grooves 46 has the same opening orientation as the side opening 412 and is arranged axially along the mating shaft 4 with the side opening 412.

[0123] The number of guiding grooves 46 can be one or multiple. By setting the opening orientation of one of them to be the same as that of the side opening 412, it is convenient to align the assembly of the sliding sleeve 5 and the mating shaft 4, facilitating the assembly of the sliding sleeve 5 onto the mating shaft 4 and improving the assembly efficiency.

[0124] In some embodiments of the present utility model, such as Figure 12 and Figure 17 shown, at least one guiding rib 54 extends axially along the sliding sleeve 5, and the end of the guiding rib 54 exceeds the axial end of the sliding sleeve 5 or is flush with the axial end of the sliding sleeve 5.

[0125] The number of guiding ribs 54 can be one or multiple. By setting the end of at least one guiding rib 54 to exceed the axial end of the sliding sleeve 5 or be flush with the axial end, it is beneficial to increase the strength of the sliding sleeve 5, enhance the guiding stability, facilitate the insertion of the guiding rib 54 into the guiding groove 46, and facilitate the assembly of the sliding sleeve 5 onto the mating shaft 4, thus improving the assembly efficiency.

[0126] In some embodiments of the present utility model, such as Figure 12 and Figure 17 shown, the sliding sleeve 5 includes an end ring portion 52 and a cantilever portion 53 arranged axially in sequence. The cantilever portion 53 includes elastic arms 531 and guiding walls 532 arranged at intervals circumferentially along the end ring portion 52. The inner surface of the guiding wall 532 is provided with guiding ribs 54, and a buckle 511 is provided at one end of the elastic arm 531 away from the end ring portion 52. As Figure 10 shown, a clamping groove 421 is formed on the outer peripheral surface of the mating shaft 4. When the sliding sleeve 5 is in the locking position, the buckle 511 is snapped into the clamping groove 421 to prevent the sliding sleeve 5 from moving axially along the mating shaft 4.

[0127] The guiding ribs 54 on the guiding wall 532 are in guiding cooperation with the guiding grooves 46 on the mating shaft 4 to guide the sliding sleeve 5 to slide axially along the mating shaft 4 without rotation; the buckle 511 of the elastic arm 531 is in snap-fit with the clamping groove 421 on the mating shaft 4, and the sliding sleeve 5 can be stably restricted in the locking position.

[0128] In some embodiments of the present utility model, such as Figure 3 and Figure 14 shown, a first annular rib 43 and a second annular rib 44 surrounding the mating shaft 4 are provided on the outer peripheral surface of the mating shaft 4. The first annular rib 43 and the second annular rib 44 are spaced apart axially along the mating shaft 4 to form a clamping groove 421 between the first annular rib 43 and the second annular rib 44. As Figure 14As shown, at least two axial ribs 49 extending along the axial direction of the mating shaft 4 are provided on the outer peripheral surface of the mating shaft 4. The two axial ribs 49 are arranged at intervals in the circumferential direction of the mating shaft 4, and a guiding groove 46 is formed between the two axial ribs 49.

[0129] A clamping groove 421 is formed between the first annular rib 43 and the second annular rib 44. The clamping groove 421 does not have to be provided along the entire circumference of the mating shaft 4. It is sufficient that the clamping groove 421 has a certain length to meet the clamping fit with the buckle 511. Therefore, the first annular rib 43 and the second annular rib 44 are connected to the side of the axial rib 49 away from the guiding groove 46, avoiding the guiding groove 46 formed between the corresponding two axial ribs 49, ensuring that the guiding rib 54 can move stably along the guiding groove 46, and improving the movement reliability of the sliding sleeve 5.

[0130] In some embodiments of the present invention, such as Figure 12 and Figure 17 shown, both the elastic arms 531 and the guiding walls 532 are multiple, and the elastic arms 531 and the guiding walls 532 are arranged alternately in the circumferential direction.

[0131] By providing multiple elastic arms 531, the clamping stability between the buckle 511 and the clamping groove 421 can be improved, the force on the sliding sleeve 5 is evenly distributed, and the sliding sleeve 5 can be stably limited in the locking position; and by providing multiple guiding walls 532, the guiding effect can be improved, and the reliability of the axial movement of the sliding sleeve 5 along the mating shaft 4 can be improved.

[0132] In some embodiments of the present invention, such as Figure 12 shown, both the elastic arms 531 and the guiding walls 532 are two, and the elastic arms 531 and the guiding walls 532 are arranged alternately in the circumferential direction. The guiding ribs 54 on the two guiding walls 532 are located on both sides in the diameter direction of the sliding sleeve 5. Correspondingly, the guiding grooves 46 are also two and are located on both sides in the diameter direction of the mating shaft 4, which can make the force on the sliding sleeve 5 evenly distributed and improve the guiding effect.

[0133] In some embodiments of the present invention, the sliding sleeve 5 is an integrally formed part, and the structural stability of the sliding sleeve 5 is strong, which can improve the working reliability of the sliding sleeve 5. The elastic arms 531 and the guiding walls 532 are made of the same material, and the thickness of the elastic arms 531 is thinner than that of the guiding walls 532, which is beneficial to the elastic deformation of the elastic arms 531; the inner surface of the guiding walls 532 is provided with guiding ribs 54, which can also strengthen the structural strength of the guiding walls 532, reduce the deformation of the guiding walls 532, and improve the mating reliability of the guiding structure.

[0134] In some embodiments of the present invention, such as Figure 2As shown in the figure, the rotating shaft 31 is provided on the air deflector 20, the quick-release assembly 32 is provided on the air conditioner main body 10, and the mating cavity 41 is in driving cooperation with the rotating shaft 31. After the rotating shaft 31 is inserted and mated with the mating shaft 4, the rotation of one of the rotating shaft 31 and the mating shaft 4 can drive the synchronous rotation of the other one of the rotating shaft 31 and the mating shaft 4, thereby realizing the rotational cooperation between the air deflector 20 and the air conditioner main body 10.

[0135] As Figure 18 shown, the quick-release assembly 32 includes a first motor 6, and the output shaft 61 of the first motor is connected to the mating shaft 4 to drive the air deflector 20 to rotate through the mating shaft 4.

[0136] The first motor 6 drives the mating shaft 4 to rotate, and the rotating shaft 31 located in the mating cavity 41 of the mating shaft 4 is driven to rotate synchronously by the mating shaft 4, so as to drive the air deflector 20 to rotate relative to the air conditioner main body 10.

[0137] In some embodiments of the present invention, as Figure 10 shown, the mating shaft 4 has a mating hole 47, and the mating cavity 41 and the mating hole 47 are arranged at intervals along the axial direction of the mating shaft 4. As Figure 14 shown, the mating hole 47 penetrates through one end face of the mating shaft 4 away from the end opening 411, so that the output shaft 61 of the first motor is axially inserted into the mating hole 47.

[0138] The output shaft 61 of the first motor is inserted into the mating hole 47, and the output shaft 61 of the first motor and the mating shaft 4 are non-rotatably mated. The rotation of the first motor 6 can drive the mating shaft 4 to rotate. By arranging the mating cavity 41 and the mating hole 47 at intervals along the axial direction of the mating shaft 4, the output shaft 61 of the first motor inserted into the mating hole 47 and the rotating shaft 31 in the mating cavity 41 do not interfere with each other, improving the working stability of the first motor 6 and the rotating shaft 31.

[0139] In some embodiments of the present invention, as Figure 18 and Figure 19 shown, the quick-release assembly 32 further includes: a mounting seat 7, the mounting seat 7 includes a partition plate 71, as Figure 20 shown, the two sides of the partition plate 71 on the axial direction of the mating shaft 4 are respectively a first side 7a and a second side 7b, the partition plate 71 has a through hole 711, the first motor 6 is installed on the mounting seat 7 and is arranged on the first side 7a, at least part of the mating shaft 4 is arranged on the second side 7b, so that the side opening 412 is located on the second side 7b, one end of the mating shaft 4 away from the partition plate 71 forms an end opening 411, the sliding sleeve 5 is arranged on the second side 7b, and is adapted to move in the direction towards the partition plate 71 from the locking position to the unlocking position.

[0140] The mounting base 7 serves to support and mount. The quick-release assembly 32 is mounted on the air conditioner body 10 through the mounting base 7, and the mating shaft 4, the sliding sleeve assembly 5, and the first motor 6 are all assembled on the mounting base 7.

[0141] When assembling or separating the rotating shaft 31 and the quick-release assembly 32, the user needs to manually drive the sliding sleeve assembly 5 to move. Therefore, by providing a partition 71 on the mounting base 7, the first motor 6 and the sliding sleeve assembly 5 can be separated to prevent the user from touching the first motor 6 and improve the safety of user operation.

[0142] By providing the partition 71, the sliding sleeve assembly 5 can also be limited. The sliding sleeve assembly 5 moves axially along the mating shaft 4 to switch between the locked position and the unlocked position. The sliding sleeve assembly 5 moves in the direction towards the partition 71 to reach the unlocked position from the locked position. When the sliding sleeve assembly 5 is in the unlocked position, the partition 71 supports the sliding sleeve assembly 5 and can limit the sliding sleeve assembly 5, thus facilitating the user to move the sliding sleeve assembly 5 from the unlocked position to the locked position again.

[0143] The partition 71 has a through hole 711 through which the output shaft 61 of the first motor or the mating shaft 4 can pass through the partition 71 so that the second motor 83 can be in transmission cooperation with the mating shaft 4.

[0144] In some embodiments of the present invention, as Figure 14 shown, an annular platform 48 surrounding the mating shaft 4 is provided at one end of the mating shaft 4 away from the opening 411 of the end, as Figure 20 shown, the mating shaft 4 is rotatably inserted through the through hole 711, and the mating shaft 4 is adapted to pass through the through hole 711 in the direction from the first side 7a to the second side 7b, and the annular platform 48 abuts against the first side 7a of the partition 71.

[0145] The output shaft 61 of the first motor is axially inserted into the mating shaft 4. The first motor 6 limits the mating shaft 4 in the direction from the second side 7b to the first side 7a. By providing the annular platform 48, the annular platform 48 is blocked by the partition 71 on the first side 7a, and the partition 71 limits the mating shaft 4 in the direction from the first side 7a to the second side 7b. The mating shaft 4 is stably assembled on the mounting base 7 in the axial direction, which can improve the working stability of the mating shaft 4.

[0146] The cross-sectional area of the mating shaft 4 at the through hole 711 is smaller than the opening area of the through hole 711. The mating shaft 4 is in clearance fit with the through hole 711, which can reduce the frictional collision between the mating shaft 4 and the partition 71 and improve the rotational stability of the mating shaft 4.

[0147] In some embodiments of the present invention, as Figure 10As shown, the outer peripheral surface of the mating shaft 4 has a card slot 421, and the sliding sleeve 5 has a buckle 511 that mates with the card slot 421. When the sliding sleeve 5 is in the locked position, the buckle 511 is engaged with the card slot 421 to limit the sliding sleeve 5 in the locked position. On the outer peripheral surface of the mating shaft 4, a first annular rib 43 and a second annular rib 44 surrounding the mating shaft 4 are provided. The first annular rib 43 and the second annular rib 44 are spaced apart along the axial direction of the mating shaft 4 to form the card slot 421 between the first annular rib 43 and the second annular rib 44.

[0148] The mating shaft 4 includes a first shaft segment and a second shaft segment connected axially. The first annular rib 43 is provided at the junction of the first shaft segment and the second shaft segment. The card slot 421 is formed in the first shaft segment. The second shaft segment passes through the through hole 711. The outer contour of the cross-section of the first shaft segment is located outside the outer contour of the cross-section of the second shaft segment, so that the mating shaft 4 can reduce the frictional collision with the partition 71 and improve the rotational stability of the mating shaft 4.

[0149] In some embodiments of the present invention, the mating shaft 4 is an integrally formed part, which can improve the integrity of the mating shaft 4. The mating shaft 4 has strong structural stability, which is beneficial to improving the working reliability of the mating shaft 4.

[0150] In some embodiments of the present invention, as Figure 17 shown, a guiding rib 54 protrudes from the inner peripheral surface of the sliding sleeve 5. As Figure 14 shown, a guiding groove 46 that mates with the guiding rib 54 is formed on the outer peripheral surface of the mating shaft 4. Through the guiding cooperation of the guiding rib 54 and the guiding groove 46, the sliding sleeve 5 can be guided to move stably between the locked position and the unlocked position, improving the movement stability of the sliding sleeve 5.

[0151] As Figure 14 shown, the guiding groove 46 is located on the second side 7b and opens towards the direction away from the partition 71 to form a notch 461. The sliding sleeve 5 is adapted to be sleeved on the mating shaft 4 along the direction from the second side 7b to the first side 7a, so that the guiding rib 54 is slidably inserted into the guiding groove 46 through the notch 461. By providing the notch 461, the assembly of the sliding sleeve 5 can be guided, improving the disassembly and assembly efficiency of the sliding sleeve 5 and the mating shaft 4.

[0152] Next, refer to Figure 18 and Figure 20 to briefly describe the assembly process of the quick-release component 32.

[0153] First, connect the output shaft 61 of the first motor to the mating shaft 4. Subsequently, assemble the entirety of the first motor 6 and the mating shaft 4 in the direction from the first side 7a to the second side 7b onto the mounting base 7. The first motor 6 is installed on the mounting base 7, and the mating shaft 4 passes through the perforation 711 on the partition plate 71 of the mounting base 7, with the side opening 412 of the mating shaft 4 extending into the second side 7b. Finally, sleeved the sliding sleeve assembly 5 onto the mating shaft 4 in the direction from the second side 7b to the first side 7a, such that the guiding rib 54 is slidably inserted into the guiding groove 46 through the notch 461, completing the assembly of the quick-release assembly 32.

[0154] In some embodiments of the present utility model, as Figure 18 and Figure 19 shown, the quick-release assembly 32 further includes a mounting base 7. The first motor 6 is installed on the mounting base 7, and a first limiting wall 72 is provided on the mounting base 7. The mounting base 7 serves the functions of support and installation. The quick-release assembly 32 is installed on the air conditioner body 10 through the mounting base 7, and the mating shaft 4, the sliding sleeve assembly 5, and the first motor 6 are all assembled on the mounting base 7.

[0155] As Figure 21 shown, the air deflector 20 includes a plate body 21 and a connecting arm 22. The connecting arm 22 is flush with or lower than the upper end of the plate body 21 and protrudes towards the windward side of the plate body 21. The shaft end of the rotating shaft 31 is connected to the connecting arm 22, and the air deflector 20 rotates relative to the air conditioner body 10 with the axis of the rotating shaft 31 as the rotation axis. The connecting arm 22 is flush with or lower than the upper end of the plate body 21. When the air deflector 20 is assembled to the air conditioner body 10, the connecting arm 22 will not interfere with the edge of the air outlet 11, improving the rotation reliability of the air deflector 20.

[0156] As Figure 22 and Figure 23 shown, when the first motor 6 reaches the set state and the connecting arm 22 abuts against the first limiting wall 72, the rotating shaft 31 aligns with the side opening 412.

[0157] During the assembly process of the air deflector 20 with the body of the air conditioner 100, the first limiting wall 72 can play a positioning role. The first motor 6 drives the mating shaft 4 to rotate. When the first motor 6 reaches the set state, the mating shaft 4 rotates to the disassembly and assembly position. When the connecting arm 22 abuts against the first limiting wall 72, the rotating shaft 31 on the air deflector 20 aligns with the side opening 412 on the mating shaft 4 at the disassembly and assembly position. By directly driving the air deflector 20 to move along the opening direction of the side opening 412, the rotating shaft 31 can be inserted into the mating cavity 41. By providing the first limiting wall 72, the assembly efficiency of the air deflector 20 can be improved.

[0158] The first limiting wall 72 can also limit the rotation of the air deflector 20. The air deflector 20 is rotatably arranged at the air outlet 11. When the air deflector 20 rotates to make the connecting arm 22 abut against the first limiting wall 72, the air deflector 20 rotates to the limit position to guide the air flow at the air outlet 11.

[0159] Moreover, the first limiting wall 72 can also play a positioning role during the disassembly process of the air deflector 20. The first motor 6 drives the cooperation shaft 4 and the rotating shaft 31 to rotate together. When the first motor 6 reaches the set state, the cooperation shaft 4 rotates to the disassembly and assembly position, and the connecting arm 22 of the air deflector 20 rotates to abut against the first limiting wall 72. At this time, as Figure 1 and Figure 7 shown, when the air deflector 20 rotates to open the air outlet 11, the user can directly access the quick-release component 32 through the air outlet 11, quickly release the connection between the quick-release component 32 and the rotating shaft 31, and improve the disassembly efficiency of the air deflector 20.

[0160] In some embodiments of the present utility model, as Figure 19 shown, the mounting seat 7 includes a concave cavity 73. The side wall of the concave cavity 73 has an avoidance opening 74. The circumferential two ends of the avoidance opening 74 are respectively a second limiting wall 75 and a third limiting wall 76. As Figure 17 shown, the outer circumference of the peripheral wall of the sliding sleeve 5 is convexly provided with a dial 55. As Figure 6 shown, when the sliding sleeve 5 is in the locked position, it moves out of the concave cavity 73. As Figure 7 shown, when in the unlocked position, it extends into the concave cavity 73 and the dial 55 extends into the avoidance opening 74. When the dial 55 rotates to abut against the second limiting wall 75, the first motor 6 presents the set state.

[0161] The mounting seat 7 has a concave cavity 73. When the sliding sleeve 5 is in the unlocked position, the sliding sleeve 5 is located in the concave cavity 73. The mounting seat 7 can support and protect the sliding sleeve 5, facilitating the user to quickly find the sliding sleeve 5 and drive the sliding sleeve 5 to move again. When the sliding sleeve 5 is in the locked position, the sliding sleeve 5 moves out of the concave cavity 73, which can avoid the interference of the mounting seat 7 when the sliding sleeve 5 rotates synchronously with the cooperation shaft 4 and improve the movement stability of the sliding sleeve 5.

[0162] The second limiting wall 75 on the mounting seat 7 can play a positioning role during the assembly process of the air deflector 20. The first motor 6 drives the cooperation shaft 4 and the sliding sleeve 5 to rotate synchronously. When the dial 55 on the sliding sleeve 5 rotates to abut against the second limiting wall 75, the second limiting wall 75 plays a positioning role, and the first motor 6 reaches the set state, and the cooperation shaft 4 rotates to the disassembly and assembly position. At this time, when the connecting arm 22 of the air deflector 20 is abutted against the first limiting wall 72, the rotating shaft 31 and the cooperation shaft 4 can be assembled and connected.

[0163] In some embodiments of the present utility model, the third limiting wall 76 on the mounting base 7 can play a positioning role during the assembly process of the mating shaft 4 and the mounting base 7. After the first motor 6 is connected to the mating shaft 4, the first motor 6 and the mating shaft 4 are integrally mounted on the mounting base 7. Then, it is necessary to bring the first motor 6 to a set state and drive the mating shaft 4 to rotate to the disassembly and assembly position, so as to facilitate the subsequent assembly of the rotating shaft 31 and the quick-release assembly 32.

[0164] After the first motor 6 and the mating shaft 4 are integrally mounted on the mounting base 7, when the sliding sleeve 5 is assembled with the mating shaft 4 and the sliding sleeve 5 is moved to the unlocking position, directly rotating the mating shaft 4 and the sliding sleeve 5 together to the position where the dial 55 abuts against the second limiting wall 75 is inaccurate, which will cause the state of the first motor 6 to be incorrect and the position of the mating shaft 4 to not meet the requirements for the quick insertion of the rotating shaft 31. In the embodiments of the present utility model, by providing the third limiting wall 76, after the mating shaft 4 and the sliding sleeve 5 are rotated together until the dial 55 abuts against the third limiting wall 76, then driving the first motor 6 to control the mating shaft 4 and the sliding sleeve 5 to rotate together until the dial 55 abuts against the second limiting wall 75, it can ensure that the mating shaft 4 accurately rotates to the disassembly and assembly position, facilitating the subsequent assembly of the rotating shaft 31 and the quick-release assembly 32, and improving the assembly efficiency.

[0165] It should be noted that the assembly of the mating shaft 4 and the mounting base 7 often occurs during the factory assembly stage or the after-sales stage of professional maintenance personnel. The process of the first motor 6 driving the dial 55 to rotate from abutting against the third limiting wall 76 to abutting against the second limiting wall 75 can be achieved by presetting a rotation angle. After the mating shaft 4 and the sliding sleeve 5 are rotated together until the dial 55 abuts against the third limiting wall 76, by controlling the motor shaft of the first motor 6 to rotate the preset angle with one key, the first motor 6 can reach the set state, further improving the assembly efficiency of the quick-release assembly 32.

[0166] In some embodiments of the present utility model, as Figure 17 shown, a dial 55 is convexly provided on the outer peripheral wall of the sliding sleeve 5.

[0167] By providing the dial 55, it is convenient to drive the sliding sleeve 5 to move between the locking position and the unlocking position, further reducing the operation difficulty of the sliding sleeve 5, improving the disassembly and assembly efficiency of the air deflector 20 and the air conditioner body 10, and facilitating the user to clean and maintain the air deflector 20.

[0168] In some embodiments of the present utility model, the mating shaft 4 and the sliding sleeve 5 are guided and mated through a guiding structure to limit the sliding of the sliding sleeve 5 relative to the mating shaft 4 along the axial direction without rotation. As Figure 5 shown, the positions of the dial 55 and the side opening 412 correspond in the circumferential direction.

[0169] By setting the guiding structure, the stability of the sliding sleeve 5 during movement between the locking position and the unlocking position can be improved, guiding the smooth movement of the sliding sleeve 5; the cooperation of the mating shaft 4 and the sliding sleeve 5 through the guiding structure can also limit the sliding sleeve 5. The sliding sleeve 5 moves axially along the mating shaft 4 to switch between the unlocking position and the locking position. The limit of the guiding mechanism can restrict the rotation of the sliding sleeve 5 relative to the mating shaft 4, improving the situation where the sliding sleeve 5 fails to open or block the side opening 412 due to misalignment of the movement of the sliding sleeve 5, and enhancing the working stability of the sliding sleeve 5.

[0170] When the sliding sleeve 5 slides axially relative to the mating shaft 4 to switch between the unlocking position and the locking position, the dial 55 always corresponds to the position of the side opening 412 in the circumferential direction. The opening direction of the side opening 412 is the installation and disassembly direction of the rotating shaft 31. The space in the opening direction of the side opening 412 is large, and the space available for the user to operate is large, which can reduce the operation difficulty for the user to drive the dial 55 to control the movement of the sliding sleeve 5 between the locking position and the unlocking position, improve the disassembly and assembly efficiency of the air deflector 20 and the air conditioner body 10, and facilitate the user to clean and maintain the air deflector 20.

[0171] In some embodiments of the present invention, as Figure 24 shown, one end on the rotation axis of the air deflector 20 is detachably and cooperatively connected to the air conditioner body 10 through the quick-release unit 30, and the other end is detachably and cooperatively connected to the air conditioner body 10 through the connection unit 80.

[0172] When the air deflector 20 is assembled with the air conditioner body 10, first, the other end on the rotation axis of the air deflector 20 is assembled and connected to the air conditioner body 10 through the connection unit 80, and then one end on the rotation axis of the air deflector 20 is quickly assembled with the air conditioner body 10 through the quick-release unit 30 to install the air deflector 20 to the air conditioner body 10. When the air deflector 20 is disassembled from the air conditioner body 10, first, one end on the rotation axis of the air deflector 20 is quickly disconnected from the air conditioner body 10 through the quick-release unit 30, and then the other end on the rotation axis of the air deflector 20 is disassembled from the air conditioner body 10 through the connection unit 80 to separate the air deflector 20 from the air conditioner body 10.

[0173] In some embodiments of the present invention, as Figure 25 shown, the connection unit 80 includes: a second rotating shaft 81 and a rotating shaft seat 82. The rotating shaft seat 82 has a shaft hole 821, and the shaft hole 821 is open along the axis direction of the second rotating shaft 81. The second rotating shaft 81 is inserted and cooperated with the shaft hole 821.

[0174] One of the rotating shaft seats 82 and the second rotating shaft 81 is arranged on the air deflector 20, and the other one of the rotating shaft seats 82 and the second rotating shaft 81 is arranged on the air conditioner body 10. The rotating shaft seat 82 and the second rotating shaft 81 are rotatably matched, and the matching selection of the rotating shaft seat 82 and the second rotating shaft 81 with the air deflector 20 and the air conditioner body 10 can be selected according to actual needs.

[0175] After the air deflector 20 is assembled to the air conditioner body 10, the first rotating shaft and the second rotating shaft 81 are coaxially arranged. The air deflector 20 rotates relative to the air outlet 11 with the axis of the second rotating shaft 81 as the rotation axis. The length direction of the air deflector 20 and the length direction of the air outlet 11 are consistent with the axial direction of the second rotating shaft 81. When the air deflector 20 and the air conditioner body 10 are assembled, first, the air deflector 20 moves relative to the air conditioner body 10 along the length direction of the air outlet 11, and the second rotating shaft 81 is inserted and matched with the shaft hole 821. Subsequently, the air deflector 20 is driven to move relative to the air conditioner body 10 along the direction perpendicular to the axis of the first rotating shaft, and the first rotating shaft and the quick-release assembly 32 can be assembled.

[0176] The disassembly of the air deflector 20 and the air conditioner body 10 is the same in principle, but the steps are opposite. First, the air deflector 20 is driven to move relative to the air conditioner body 10 along the direction perpendicular to the axis of the first rotating shaft to separate the first rotating shaft and the quick-release assembly 32; then, the air deflector 20 is driven to move relative to the air conditioner body 10 along the length direction to take out the second rotating shaft 81 from the shaft hole 821 and separate the second rotating shaft 81 and the rotating shaft seat 82.

[0177] In some other embodiments of the present invention, both ends on the rotation axis of the air deflector 20 are detachably and assembled with the air conditioner body 10 through the quick-release unit 30. By directly driving the air deflector to move relative to the air conditioner body 10 along the direction perpendicular to the axis of the first rotating shaft, both ends on the rotation axis of the air deflector 20 can be assembled or disassembled with the quick-release assembly 32, further improving the disassembly and assembly efficiency of the air deflector 20.

[0178] In some embodiments of the present invention, as Figure 1 shown, the rotation axis of the air deflector 20 extends in the up and down direction, the quick-release unit 30 is arranged at the upper end of the air outlet 11, and the connecting unit 80 is arranged at the lower end of the air outlet 11.

[0179] When the air deflector 20 and the air conditioner body 10 are assembled, the lower end of the air deflector 20 is first assembled with the air conditioner body 10, and then the upper end of the air deflector 20 is assembled with the air conditioner body 10. After the lower end of the air deflector 20 is assembled with the air conditioner body 10 through the connecting unit 80, the lower end of the air outlet 11 supports the air deflector 20, and it is not necessary to hold the air deflector 20 for assembly. The gravity influence of the air deflector 20 is small, reducing the operation difficulty.

[0180] In some embodiments of the present invention, as Figure 25 and Figure 26As shown, a rotating shaft seat 82 is provided at the lower end of the air deflector 20, and a second rotating shaft 81 is correspondingly provided on the air conditioner main body 10. When the air deflector 20 moves downward along the axial direction of the second rotating shaft 81 to insert and fit the second rotating shaft 81 with the shaft hole 821, one end of the air deflector 20 can be assembled with the air conditioner main body 10.

[0181] As Figure 25 and Figure 26 shown, the connecting unit 80 includes a second motor 83. The output shaft 831 of the second motor is the second rotating shaft 81 and extends upward. The rotating shaft seat 82 is sleeved downward outside the second rotating shaft 81 through the shaft hole 821, and the second rotating shaft 81 is in driving cooperation with the rotating shaft seat 82.

[0182] The output shaft 831 of the second motor is the second rotating shaft 81. The second rotating shaft 81 can not only be inserted and fitted with the rotating shaft seat 82, but also provide power for the rotation of the air deflector 20 to drive the air deflector 20 to rotate relative to the air outlet 11.

[0183] In some embodiments of the present utility model, a rotating shaft seat 82 is provided at the lower end of the air deflector 20, and a second rotating shaft 81 is correspondingly provided on the air conditioner main body 10; a first rotating shaft is provided at the upper end of the air deflector 20, and a quick-release assembly 32 is provided at the upper end of the air outlet 11 of the air conditioner main body 10.

[0184] The connecting unit 80 includes a second motor 83. The output shaft 831 of the second motor is the second rotating shaft 81 and extends upward. The rotating shaft seat 82 is sleeved downward outside the second rotating shaft 81 through the shaft hole 821, and the second rotating shaft 81 is in driving cooperation with the rotating shaft seat 82; the quick-release assembly 32 includes a first motor 6 and a mating shaft 4. A side opening 412 is formed on the outer peripheral surface of the mating shaft 4. The first rotating shaft extends into and is connected with the mating shaft 4 through the side opening 412. The first motor 6 is provided below the mating shaft 4, and the output shaft 61 of the first motor is inserted upward into the mating shaft 4 to drive the first rotating shaft to rotate through the mating shaft 4.

[0185] The first rotating shaft and the second rotating shaft 81 are coaxially arranged. The first motor 6 and the second motor 83 jointly drive the air deflector 20 to rotate relative to the air conditioner main body 10 from the upper and lower ends of the air deflector 20. By driving the air deflector 20 to rotate at both the upper and lower ends of the air deflector 20 body, the rotation stability of the air deflector 20 can be improved, and the working reliability of the air deflector 20 can be improved.
