DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0045] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0046] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0047] The embodiment of the present application provides a ceiling air outlet device, Figure 1 This is the structural explosion diagram of the ceiling air outlet device. Figure 1 As shown, the ceiling air outlet device includes a shell 1, an air outlet assembly 2, a connecting bracket 3, a first driving assembly 4 and a second driving assembly 5.

[0048] A first rotating portion 31 is provided on the outer wall of the connecting bracket 3, and the shell 1 includes a panel 11 and a chassis 12. The chassis 12 is open on one side and has a accommodating cavity inside, which is used to accommodate multiple functional components of the ceiling air outlet device including the air outlet assembly 2, the connecting bracket 3, the first drive assembly 4 and the second drive assembly 5; the panel 11 is covered on the open side of the chassis 12, and an air outlet 111 is provided on the panel 11, which is connected to the accommodating cavity to allow the airflow generated inside the chassis 12 to be blown out therefrom.

[0049] The vent assembly 2 is installed at the air outlet 111 and has an air guide port. The air flow blown out from the inside of the chassis 12 is blown out through the air guide port of the vent assembly 2. The vent assembly 2 plays a guiding role and can control the direction of the air flow blown out from the inside of the chassis 12. Among them, one side of the vent assembly 2 is exposed to the shell 1 through the air outlet 111 to ensure the smooth blowing of the air flow. It should be noted that one side of the vent assembly 2 is "exposed to" the shell 1, including the situation that the vent assembly 2 is completely located inside the shell 1 and one side of the vent assembly 2 can be seen along the axial direction of the air outlet 111, and also includes the situation that one side of the vent assembly 2 extends to the outside of the shell 1 through the air outlet 111.

[0050] The connecting bracket 3 is on the other side surrounding the air outlet assembly 2, and is used to connect the air outlet assembly 2 and the shell 1. The connecting bracket 3 is rotatably connected to the air outlet assembly 2 around the first axis to change the position and orientation of the air outlet assembly 2 in the air outlet 111, so that the air outlet assembly 2 can blow out airflow in different directions on the circumference; and the connecting bracket 3 is rotatably installed on the shell 1 around the second axis to change the position and orientation of the connecting bracket 3 relative to the shell 1, so that the connecting bracket 3 drives the air outlet assembly 2 to rotate in different directions on the circumference. Since the first axis and the second axis intersect or stagger with the axis of the air outlet 111 respectively, and the orthographic projection of the first axis on the opening plane of the air outlet 111 intersects with the orthographic projection of the second axis on the opening plane, the air outlet assembly 2 can blow out airflow in different directions in the space, thereby increasing the air sweeping range of the air outlet assembly 2 and improving the air supply flexibility. It should be noted that, in the embodiment of the present application, the axis of the air outlet 111 refers to a straight line passing through the center of the air outlet 111 and perpendicular to the opening plane of the air outlet 111, wherein the opening plane of the air outlet 111 is the plane where the air outlet 111 is located. The first axis and the second axis intersect or stagger with the axis of the air outlet 111, respectively, which means that the first axis and the second axis are neither parallel to each other nor coincide with each other. For example, the first axis and the second axis can be located on the same plane and intersect with each other (including perpendicular situations), or the first axis and the second axis can be located on different planes and staggered with each other. For example, Fig.21 As shown, on the opening plane of the air outlet 111 , the orthographic projection of the first axis is perpendicular to the orthographic projection of the second axis.

[0051] The first drive assembly 4 and the second drive assembly 5 are connected to the connection bracket 3 and the tuyere assembly 2, respectively, and are used to drive the connection bracket 3 and the tuyere assembly 2 to rotate. The following is an example in which the first drive assembly 4 is used to drive the connection bracket 3 to rotate around the second axis, and the second drive assembly 5 is used to drive the tuyere assembly 2 to rotate around the first axis. The first drive assembly 4 and the second drive assembly 5 can be either drive devices manually controlled by the user, or drive devices that can be automatically controlled based on electrical signals.

[0052] In summary, the ceiling air outlet device provided in the embodiment of the present application uses one side of the air outlet assembly 2 to discharge air, and the other side is rotatably connected to the connecting bracket 3. The second driving assembly 5 can drive the air outlet assembly 2 to rotate around the first axis; the connecting bracket 3 is rotatably connected to the shell 1, and the first driving assembly 4 can drive the connecting bracket 3 to rotate around the second axis. Among them, the first axis and the second axis are respectively intersected or staggered with the axis of the air outlet 111, so as to realize the rotational sweeping of air in two intersecting planes with the rotation of the air outlet assembly 2 and / or the connecting bracket 3, the ceiling air outlet device can realize the rotational sweeping of air in two intersecting planes, that is, realize the rotational sweeping of air in a 360° space, and the air supply angle can be flexibly and accurately controlled, which significantly expands the air supply range.

[0053] The connecting bracket 3 can be installed on the panel 11. In some embodiments of the present application, such as Figure 2 As shown, the inner surface 112 of the panel 11 facing the accommodating cavity is provided with a first rotating portion 31, and the outer wall of the connecting bracket 3 is provided with a first rotating portion 31. The first rotating portion 31 and the second rotating portion 13 are rotatably connected around the second axis, so as to realize the installation of the connecting bracket 3 on the panel 11. Exemplarily, an axial hole can be provided on the second rotating portion 13, and the first rotating portion 31 can be rotatably located in the axial hole of the corresponding first rotating portion 31.

[0054] In one example, the number of the first rotating parts 31 is two, the two first rotating parts 31 are arranged on opposite sides of the air outlet 111, and the axes of the two first rotating parts 31 coincide with the second axis respectively; the number of the first rotating parts 31 is two, the two first rotating parts 31 are arranged on opposite sides of the connecting bracket 3, and the axes of the two first rotating parts 31 coincide with the second axis respectively, and the two first rotating parts 31 are rotatably located in the axial holes of the two first rotating parts 31 respectively.

[0055] Of course, in some other embodiments of the present application, the connecting bracket 3 may also be installed on the chassis 12. In this case, the first rotating portion 31 is arranged at a suitable position inside the chassis 12, so that the connecting bracket 3 can drive the air outlet assembly 2 to rotate in the air outlet 111. Alternatively, in other embodiments, the connecting bracket 3 may also be installed on other components of the ceiling air outlet device according to actual needs, such as on an air guide baffle between the panel 11 and the wind wheel assembly 6, and the air guide baffle may be provided with an air inlet for conveying outside air to the wind wheel assembly 6. Optionally, the air inlet of the ceiling air outlet device may be provided on the side of the shell 1, such as between the panel 11 and the chassis 12, and the outside air enters between the air guide baffle and the panel 11 from the air inlet, and enters the wind wheel assembly 6 from the air inlet on the air guide baffle.

[0056] In some embodiments of the present application, Figure 3As shown, the orthographic projection of the connecting bracket 3 on the opening plane of the air outlet 111 has an overlapping area with the panel 11 , so that the first rotating part 31 on the connecting bracket 3 can be assembled to the first rotating part 31 arranged on the periphery of the air outlet 111 .

[0057] At the same time, in order to prevent the connecting bracket 3 that can rotate around the second axis from colliding with the inner surface 112 of the panel 11 during the rotation process, thereby preventing the rotation from being blocked or generating collision noise, such as Figure 4 As shown, along the opening direction of the air outlet 111, there is a first interval 100 between the connecting bracket 3 and the inner surface 112 of the panel 11, and at any time during the rotation of the connecting bracket 3, the width of the first interval 100 is greater than or equal to zero, wherein the width direction of the first interval 100 is parallel to the axial direction of the air outlet 111. Due to the existence of the first interval 100, during the rotation of the connecting bracket 3 and when the connecting bracket 3 reaches the maximum rotation angle, the distance between the connecting bracket 3 and the inner surface 112 of the panel 11 is always greater than or equal to zero, thereby avoiding a strong collision between the connecting bracket 3 and the panel 11.

[0058] The driving method of the first driving component 4 for the connecting bracket 3 and the related structure can be designed according to actual needs.

[0059] In some embodiments, the first driving assembly 4 can be directly connected to the first rotating portion 31 to directly drive the connecting bracket 3 to rotate. Figure 7 As shown, the first rotating part 31 has one of a rotating shaft and an axial hole, and the second rotating part 13 has the other of the rotating shaft and the axial hole; the first driving assembly 4 includes a first motor 41, and the output shaft of the first motor 41 is directly in phase with the rotating shaft to drive the first rotating part 31 to rotate. It should be noted that the first motor 41 is "directly connected" to the first rotating part 31, which means that there is no other connection structure between the first motor 41 and the first rotating part 31.

[0060] In this case, the output shaft of the first motor 41 is coaxial with the first rotating part 31, that is, the axes are both the second axis, wherein the second axis can be parallel, perpendicular or intersecting with the width direction of the panel 11. Since the axis of the output shaft of the first motor 41 coincides with the second axis, when the extension direction of the second axis is parallel to the width direction of the panel 11, the first motor 41 usually needs to be arranged on one side of the air outlet 111 along the width direction of the panel 11, that is, it is necessary to reserve the installation position of the first motor 41 in the width direction of the panel 11. In order to avoid the installation position of the first motor 41 causing the opening area of ​​the air outlet 111 to be reduced and thus affecting the air volume, in some embodiments, the installation position of the first motor 41 can be offset relative to the air outlet 111 in the width direction of the panel 11, that is, the orthographic projection of the second axis on the opening plane of the air outlet 111 is offset relative to the center of the air outlet 111.

[0061] In other embodiments, the first driving assembly 4 may be indirectly connected to the first rotating portion 31 through other transmission components to indirectly drive the connecting bracket 3 to rotate. Figure 2 A first transmission part 32 is disposed on the outer wall of the connecting bracket 3. The first transmission part 32 is located on one side of the first rotating part 31 and is connected to or matched with the first driving component 4. Figure 5 As shown, there is a second interval 200 between the orthographic projection of the first transmission part 32 on the opening plane of the air outlet 111 and the orthographic projection of the first rotating part 31 on the opening plane of the air outlet 111 .

[0062] In this case, the output shaft of the first driving assembly 4 is not coaxial with the first rotating part 31, for example, see Figure 2 and Figure 3 , the axis of the output shaft of the first drive assembly 4 is parallel to and does not overlap with the second axis, wherein the second axis may be parallel to, perpendicular to, or intersecting with the width direction of the panel 11. Optionally, when the extension direction of the second axis is parallel to the width direction of the panel 11, the orthographic projection of the axis of the output shaft of the first drive assembly 4 on the opening plane of the air outlet 111 is offset relative to the center of the air outlet 111, so as to avoid the installation position of the first drive assembly 4 causing the opening area of ​​the air outlet 111 to be reduced and thus affecting the air volume.

[0063] In some embodiments, Figure 6 As shown, the first transmission part 32 has a first gear 321, and the first driving component 4 cooperates with the first gear 321 to drive the connecting bracket 3 to rotate. Among them, the center of the first gear 321 is located on the second axis, and there is a second interval 200 between the first gear 321 and the first rotating part 31. Compared with the solution in which the first driving component 4 directly drives the first rotating part 31, this embodiment indirectly drives through the first gear 321 of the first transmission part 32, amplifies the torque of the first driving component 4, can achieve a more labor-saving effect, and reduce costs. Optionally, the first transmission part 32 can be a circular gear, a sector gear or an arc rack.

[0064] Optionally, continue to see Figure 6 The first driving assembly 4 can be installed on the panel 11, and includes a first motor 41 and a first gear 42. The output shaft of the first motor 41 is passed through the shaft hole of the first gear 42 and is fixedly connected to the first gear 42; the first gear 42 is engaged with the first gear teeth 321 of the first transmission part 32, so that when the output shaft of the first motor 41 rotates, the power is transmitted to the first rotating part 31 through the first gear 42, thereby driving the connecting bracket 3 to rotate.

[0065] See also Figure 8 and Fig. 9In some embodiments of the present application, the air outlet assembly 2 includes a first air guide 21, one side of the first air guide 21 is located inside the connection bracket 3 to receive the airflow generated in the chassis 12, and the other side of the first air guide 21 is exposed from the air outlet 111 to allow the airflow to pass through and be blown out to the outside of the chassis 12. A third rotating portion 22 is provided on the outer wall of one side of the first air guide 21 located inside the connection bracket 3, and a fourth rotating portion 33 is provided on the connection bracket 3. The third rotating portion 22 and the fourth rotating portion 33 can be rotatably connected around the first axis, thereby realizing the installation of the first air guide 21 and the connection bracket 3.

[0066] In one example, there are two fourth rotating parts 33, which are arranged on opposite sides of the inner wall of the connecting bracket 3, and the axes of the two fourth rotating parts 33 coincide with the first axis respectively; there are two third rotating parts 22, which are arranged on opposite sides of the first air guide member 21, and the axes of the two third rotating parts 22 coincide with the first axis respectively, and the two third rotating parts 22 are rotatably located in the two fourth rotating parts 33 respectively.

[0067] A third interval 300 is provided between the outer wall of the first air guide 21 and the connecting bracket 3 to prevent the first air guide 21 from colliding with the connecting bracket 3 when the first air guide 21 rotates under the drive of the second driving assembly 5, thereby preventing the first air guide 21 from being blocked from rotating or generating collision noise, such as Fig. 9 As shown, along the opening direction of the air outlet 111, there is a third interval 300 between the inner wall of the connecting bracket 3 and the outer wall of the first air guide 21 (except for the part with the third rotating part 22), and at any time during the rotation of the first air guide 21, the width of the third interval 300 is greater than or equal to zero, wherein the width direction of the third interval 300 is parallel to the radial direction of the air guide port of the first air guide 21. Due to the existence of the third interval 300, during the rotation of the first air guide 21, and when the first air guide 21 reaches the maximum rotation angle, the distance between the first air guide 21 and the connecting bracket 3 is always greater than or equal to zero, thereby avoiding a strong collision between the first air guide 21 and the connecting bracket 3.

[0068] The driving method and related structures of the second driving component 5 for the first air guide member 21 can be designed according to actual needs.

[0069] In some embodiments, the second driving assembly 5 can be directly connected to the third rotating part 22 to directly drive the connecting bracket 3 to rotate. Fig.17As shown, the third rotating part 22 has one of a rotating shaft and an axial hole, and the fourth rotating part 33 has the other of a rotating shaft and an axial hole; the second driving assembly 5 includes a second motor 51, and the output shaft of the second motor 51 is directly in phase with the rotating shaft to drive the third rotating part 22 to rotate. In this case, the output shaft of the second motor 51 is coaxial with the third rotating part 22. When the extension direction of the first axis is parallel to the width direction of the housing 1, it is usually necessary to reserve the installation position of the second motor 51 in the width direction of the panel 11. In order to avoid the installation position of the second motor 51 causing the opening area of ​​the air guide port of the first air guide member 21 to be reduced and affect the air volume, in some embodiments, the installation position of the second motor 51 can be offset relative to the air guide port in the width direction of the panel 11, that is, the orthographic projection of the first axis on the opening plane of the air guide port is offset relative to the center of the air guide port. Optionally, the orthographic projection of the center of the air guide port on the opening plane of the air outlet 111 coincides with the center of the air outlet 111.

[0070] In other embodiments, the second driving assembly 5 may be indirectly connected to the third rotating part 22 through other transmission components to indirectly drive the first air guide member 21 to rotate. Fig. 9 As shown, a second transmission part 23 is provided on the outer wall of the first air guide member 21, the second transmission part 23 is located on one side of the third rotating part 22, and is connected to or cooperates with the second driving assembly 5, wherein there is a fourth interval 400 between the orthographic projection of the second transmission part 23 on the opening plane of the air outlet 111 and the orthographic projection of the third rotating part 22 on the opening plane of the air outlet 111.

[0071] In this case, the output shaft of the second drive assembly 5 is not coaxial with the third rotating part 22, for example, see Fig. 9 , the axis of the output shaft of the second drive assembly 5 is parallel to and does not overlap with the first axis, wherein the first axis may be parallel to, perpendicular to, or intersecting with the width direction of the panel 11. Optionally, when the extension direction of the first axis is parallel to the width direction of the panel 11, the orthographic projection of the axis of the output shaft of the second drive assembly 5 on the opening plane of the air guide port is offset relative to the center of the air guide port, so as to avoid the installation position of the second drive assembly 5 causing the opening area of ​​the air guide port to be reduced and thus affecting the air volume.

[0072] In some embodiments, Fig.10As shown, the second transmission part 23 has a second gear 231, and the second drive assembly 5 cooperates with the second gear 231 to drive the first air guide 21 to rotate. Among them, the center of the second gear 231 is located on the first axis, and there is a gap between the second gear 231 and the third rotating part 22. Compared with the solution in which the second drive assembly 5 directly drives the third rotating part 22, this embodiment indirectly drives through the second gear 231 of the second transmission part 23, amplifying the torque of the second drive assembly 5, achieving a more labor-saving effect, and reducing costs. Optionally, the second transmission part 23 can be a circular gear, a sector gear or an arc-shaped rack.

[0073] Alternatively, if Figures 9 to 11 As shown, the second driving assembly 5 can be installed and fixed on the connecting bracket 3, including a second motor 51 and a second gear 52. The second motor 51 is fixed on the outer side of the connecting bracket 3, and the output shaft of the second motor 51 passes through the through hole 34 on the connecting bracket 3 and extends into the inner side of the connecting bracket 3; the second gear 52 is located on the inner side of the connecting bracket 3, and the part of the output shaft of the second motor 51 located on the inner side of the connecting bracket 3 is passed through the shaft hole of the second gear 52 and is fixedly connected to the second gear 52. The second gear 52 is also engaged with the second gear teeth 231 of the second transmission part 23, so that when the output shaft of the second motor 51 rotates, the power is transmitted to the third rotating part 22 through the second gear 52, thereby driving the connecting bracket 3 to rotate.

[0074] In some embodiments of the present application, Fig.11 As shown, a limiting portion 35 is provided on the inner wall of the connecting bracket 3, and the limiting portion 35 and the through hole 34 on the connecting bracket 3 have a fifth interval 500 in the axial direction of the through hole 34, and the orthographic projection of the limiting portion 35 on the setting plane and the orthographic projection of the through hole 34 on the setting plane have an overlapping area, wherein the setting plane is perpendicular to the axial direction of the through hole 34. That is to say, in the axial direction of the through hole 34, the limiting portion 35 and the through hole 34 have a portion that is directly opposite to each other.

[0075] The second gear 52 is located in the fifth interval 500, that is, between the limiting portion 35 and the through hole 34, wherein the width dimension of the fifth interval 500 is greater than the axial length of the second gear 52, so that the second gear 52 can rotate in the fifth interval 500, and the width direction of the fifth interval 500 is parallel to the axial direction of the second gear 52 and parallel to the axial direction of the through hole 34.

[0076] In some embodiments of the present application, Fig.12As shown, the second gear 52 has a first structure 521 on the side away from the second motor 51, and the center line of the first structure 521 coincides with the axis of the output shaft of the second motor 51; the surface of the limiting portion 35 facing the through hole 34 has a second structure 351, and the second structure 351 and the first structure 521 can cooperate in relative rotation to support the second gear 52 and limit the position of the second gear 52 in the fifth interval 500.

[0077] Optionally, the first structure 521 and the second structure 351 are respectively one of a concave structure and a convex structure, and at least a portion of the convex structure is located in the concave structure to play a supporting and limiting role. Exemplarily, the first structure 521 is a concave structure, and the second structure 351 is a convex structure; or, the first structure 521 is a convex structure, and the second structure 351 is a concave structure.

[0078] In some embodiments, the recessed structure may be a groove 5211, and the groove 5211 may be in a frustum shape, such as Fig.13 As shown, the groove 5211 has an opposite open end 52111 and a bottom wall 52112, and the cross-sectional area of ​​the groove 5211 gradually decreases from the open end 52111 of the groove 5211 to the bottom wall 52112. Correspondingly, the protrusion structure can be a protrusion 3511, and the protrusion 3511 is conical or frustum-shaped. Fig.13 The protrusion 3511 has a top end 35111 and a bottom end 35112 opposite to each other, and the cross-sectional area of ​​the protrusion 3511 gradually increases from the top end 35111 to the bottom end 35112 of the protrusion 3511. When the protrusion 3511 is located in the groove 5211, the top end 35111 of the protrusion 3511 is close to or in contact with the bottom wall 52112 of the groove 5211; the bottom end 35112 of the protrusion 3511 is close to the opening end 52111 of the groove 5211.

[0079] By adopting the groove 5211 and the protrusion 3511 of the above-mentioned shape, when assembling the second gear 52, the protrusion 3511 can be easily inserted into the groove 5211, thereby reducing the difficulty of assembling the second gear 52.

[0080] Continue to see Fig.13, the groove 5211 has a first side wall 52113 located between the open end 52111 and the bottom wall 52112, and the protrusion 3511 has a second side wall 35113 located between the top end 35111 and the bottom end 35112, wherein when the protrusion 3511 is located in the groove 5211, there is a sixth interval 600 between the first side wall 52113 and the second side wall 35113. That is to say, after the second gear 52 is assembled, the protrusion 3511 and the groove 5211 are in point contact or surface contact with a very small area, thereby greatly reducing the friction force suffered by the second gear 52 during rotation, reducing the power loss of the second motor 51, and helping to achieve precise control of the rotation angle of the first air guide 21.

[0081] In some embodiments of the present application, Fig.14 As shown, the second gear 52 includes a wheel portion 522 and a tooth portion 523 . The wheel portion 522 is fixedly connected to the output shaft of the second motor 51 , and the tooth portion 523 is connected to the outer peripheral wall of the wheel portion 522 , for example, connected to a portion of the outer peripheral wall of the wheel portion 522 .

[0082] like Fig.15 As shown, the limiting portion 35 includes a first plate body 352, a second plate body 353 and a stop rib 354. The first side of the first plate body 352 is connected to the inner wall of the connecting bracket 3, and the second side is suspended, the first side and the second side are opposite, the plate surface of the first plate body 352 is perpendicular to the axial direction of the through hole 34, and the fifth interval 500 is provided between the first plate body 352 and the through hole 34. The second plate body 353 is located in the fifth interval 500, and one side of the second plate body 353 is connected to the plate surface of the first plate body 352 located at the first plate body 352, and the other side of the second plate body 353 is connected to the connecting bracket 3, the plate surface of the second plate body 353 is parallel to the axial direction of the through hole 34, and the second gear 52 is located on one side of the second plate body 353 close to the second side of the first plate body 352. The stop rib 354 is provided on the plate surface of the second plate body 353 close to the second gear 52, and is opposite to the partial position of the wheel portion 522 of the second gear 52 where the tooth portion 523 is not provided, as shown in FIG. Fig.16 As shown, there is a seventh interval 700 between the stop rib 354 and the wheel portion 522 of the second gear 52, and the width of the seventh interval 700 is less than the height of the tooth portion 523 of the second gear 52. Therefore, the stop rib 354 plays a role in limiting the rotation angle of the second gear 52. Specifically, when the second gear 52 reaches the maximum rotation angle in the clockwise direction, the stop rib 354 abuts against the tooth portion 523 on one side of the second gear 52 and prevents the second gear 52 from continuing to rotate; when the second gear 52 reaches the maximum rotation angle in the counterclockwise direction, the stop rib 354 abuts against the tooth portion 523 on the other side of the second gear 52 and prevents the second gear 52 from continuing to rotate, thereby preventing the first air guide 21 from over-rotating and blocking the air guide port.

[0083] In some embodiments of the present application, Fig.18 As shown, the ceiling air outlet device also includes a wind wheel assembly 6, which is used to stir the air in the chassis 12 to form a flowing "wind" (i.e., airflow), and the wind wheel assembly 6 is installed in the accommodating cavity of the chassis 12 and is connected to the chassis 12. The wind wheel assembly 6 may include a wind wheel 61 and a second air guide 62, and the wind wheel 61 can rotate and generate wind; the second air guide 62 is fixed on the chassis 12, and is used to transport the wind generated by the wind wheel 61 to the first air guide 21, wherein the air supply end 621 of the second air guide 62 is located on the side of the first air guide 21 away from the connecting bracket 3, that is, located on the inner side of the first air guide 21, so that the wind generated by the wind wheel 61 can be transported to the first air guide 21 as completely as possible. As shown Fig.19 As shown, there is an eighth interval 800 between the air supply end 621 of the second air guide 62 and the inner wall of the first air guide 21 to prevent the first air guide 21 from colliding with the second air guide 62 during rotation, thereby preventing the rotation from being hindered or generating collision noise. Fig.19 As shown, there is an eighth interval 800 between the inner wall of the first air guide 21 and the outer wall of the second air guide 62, and at any time during the rotation of the first air guide 21, the width of the eighth interval 800 is greater than or equal to zero, wherein the width direction of the eighth interval 800 is parallel to the radial direction of the air guide port of the first air guide 21. Due to the existence of the eighth interval 800, during the rotation of the first air guide 21, and when the first air guide 21 reaches the maximum rotation angle, the distance between the inner wall of the first air guide 21 and the outer wall of the second air guide 62 is always greater than or equal to zero, thereby avoiding the strong collision of the first air guide 21 with the second air guide 62.

[0084] In some embodiments of the present application, the second air guide 62 is spaced apart from the panel 11, and the orthographic projection of the second air guide 62 on the opening plane of the air outlet 111 is located on the inner side of the air outlet 111, so as to ensure that the airflow blown out by the second air guide 62 can flow directly to the air outlet 111 without changing direction, thereby reducing the energy loss of the airflow and ensuring the air output volume and air output range.

[0085] In some embodiments of the present application, the chassis 12 includes a box body 121 and an air guide baffle 122. The box body 121 is open on one side close to the panel 11. The air guide baffle 122 is located on the open side of the box body 121 and is located between the wind wheel 61 and the second air guide member 62. The second air guide member 62 is fixed to the air guide baffle 122. An air inlet 1221 and an air supply outlet 1222 are arranged at intervals on the air guide baffle 122. The wind wheel 61 corresponds to the position of the air inlet 1221, and the second air guide member 62 corresponds to the position of the air supply outlet 1222.

[0086] In some embodiments of the present application, the intersection of the first axis and the second axis is located on the center line of the second air guide 62. Therefore, during the rotation of the first air guide 21 relative to the shell 1, the second air guide 62 always corresponds to the rotation center of the first air guide 21, thereby ensuring that the airflow transported by the second air guide 62 can flow into the first air guide 21 as much as possible, thereby ensuring the air output of the ceiling air outlet device.

[0087] In some embodiments of the present application, the center of the air outlet 111 is located on the center line of the second air guide 62, so the second air guide 62 and the air outlet 111 are arranged on the same center line, so that the airflow blown out through the second air guide 62 can be blown out directly from the air outlet 111, reducing the direction change and kinetic energy loss of the airflow during the flow process, thereby ensuring the air volume and air outlet distance.

[0088] In some embodiments of the present application, the first air guide 21 is in the shape of a spherical table, and the center of the first air guide 21 is located on the center line of the second air guide 62. Therefore, the first air guide 21 and the second air guide 62 are ensured to be co-centered, so that no matter how the first air guide 21 rotates, the airflow conveyed by the second air guide 62 can flow into the first air guide 21 as much as possible; and visually, the relative distance between the first air guide 21 and the second air guide 62 remains unchanged, that is, the width dimension of the eighth interval 800 remains unchanged, making the structure more compact.

[0089] In some embodiments of the present application, Fig.18 and Fig. 20 As shown, the panel 11 and the chassis 12 are respectively connected to the keel assembly 7 to suspend the ceiling air outlet device on the installation carrier, and the installation carrier can be, for example, a ceiling, a suspended ceiling, etc. There is a ninth interval 900 between the connecting bracket 3 and the keel assembly 7 to prevent the connecting bracket 3 from colliding with the keel assembly 7 during the rotation process, being hindered from rotating or generating collision noise. At any time during the rotation of the connecting bracket 3, the width of the ninth interval 900 is greater than or equal to zero, wherein the width direction of the ninth interval 900 is the vertical direction of the connecting bracket 3 and the keel assembly 7. Due to the existence of the ninth interval 900, during the rotation of the connecting bracket 3, and when the connecting bracket 3 reaches the maximum rotation angle, the distance between the connecting bracket 3 and the keel assembly 7 is always greater than or equal to zero, thereby avoiding a strong collision between the connecting bracket 3 and the keel assembly 7.

[0090] In some embodiments of the present application, the ceiling air outlet device is a bathroom heater or a clothes drying machine. Optionally, the ceiling air outlet device may also have a heating component, which is used to heat the airflow blown out by the wind wheel component 6.
