DETAILED DESCRIPTION

[0047] In the description of this embodiment, it should be understood that the terms "length", "width", "height", "up", "down", "left", "right", "vertical", "horizontal", "bottom", "inside", "outside", "front", "back", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0048] As a specific embodiment of the present invention, Figure 1-Figure 5As shown, this embodiment provides an air treatment device 100, which may include a housing 110, at least one air guide mechanism 120, at least one driving mechanism 130 and a controller (not shown in the figure), wherein the housing 110 may include an air outlet duct 111. At least one air guide mechanism 120 is arranged at the air outlet duct 111, and swings at the air outlet duct 111 in a controlled manner. Each air guide mechanism 120 is also provided with a bottom plate 121 and at least one air guide blade 122 rotatably connected to the bottom plate 121. At least one driving mechanism 130 is arranged at the corresponding air guide mechanism 120, and each driving mechanism 130 is connected to the bottom plate 121 of the air guide mechanism 120 and at least one air guide blade 122 on the bottom plate 121 to controllably drive the corresponding bottom plate 121 and the air guide blade 122 to rotate. The controller is used to control the driving mechanism 130 to drive the bottom plate 121 and / or the air guide blades 122 to rotate, and is configured to control the driving mechanism 130 to drive the bottom plate 121 and the air guide blades 122 to rotate simultaneously when the air supply angle is greater than a preset angle. When the air supply angle is less than or equal to a preset angle, the driving mechanism 130 is controlled to drive the air guide blades 122 to rotate. The preset angle is the maximum angle at which the air guide blades 122 rotate.

[0049] Specifically, the air treatment device 100 of this embodiment may include a housing 110, at least one air guide mechanism 120, at least one driving mechanism 130 and a controller. The controller may control the driving mechanism 130 to drive the bottom plate 121 and the air guide blades 122 on the air guide mechanism 120 to rotate, thereby increasing the air guide angle of the air guide mechanism 120, improving the blowing coverage area of ​​the air treatment device 100, making the temperature uniformity of the room better, improving the comfort of different positions in the room, and improving the user experience. In addition, since the bottom plate 121 and the air guide blades 122 of the same air guide mechanism 120 are driven by the same driving mechanism 130, the problem of a large number of driving mechanisms 130 and a large occupied space caused by the driving mechanisms 130 of the bottom plate 121 and the air guide blades 122 being driven separately is avoided, thereby reducing the number and occupied space of the driving mechanisms 130 of the entire air treatment device 100.

[0050] Specifically, the number of the air guide mechanism 120 of this embodiment may be one or more, and at least one air guide blade 122 may be provided on each air guide mechanism 120. Preferably, a plurality of air guide blades 122 may be provided on each air guide mechanism 120. Specifically, each air guide mechanism 120 may drive the bottom plate 121 and the plurality of air guide blades 122 to rotate. Preferably, the number of the air guide mechanism 120 of this embodiment is two. The number of the driving mechanism 130 may also be two, which are respectively provided at the corresponding air guide mechanism 120.

[0051] As a specific embodiment of the present invention, Figure 4 and Figure 5As shown, each driving mechanism 130 of this embodiment may include a driving motor 131 and a driving assembly 132. The driving motor 131 is connected to the controller to receive the control instruction of the controller and moves according to the control instruction. The driving motor 131 may include an output shaft. One side of the driving assembly 132 is connected to the output shaft of the driving motor 131, and the other side is connected to the bottom plate 121 and the wind guide blade 122 to drive the bottom plate 121 and / or the wind guide blade 122 to rotate under the drive of the driving motor 131.

[0052] Specifically, in this embodiment, the same drive motor 131 and drive assembly 132 can drive the base plate 121 and the wind guide blades 122 to move, thereby reducing the number of motors used and the space occupied, reducing the occupied volume of the air treatment device 100, and facilitating the miniaturization of the device.

[0053] As a specific embodiment of the present invention, each driving assembly 132 of this embodiment may include a first gear 1321, which is connected to one of the wind guide blades 122 and is coaxially linked with the wind guide blade 122. The first gear 1321 rotates under the drive of the driving motor 131, thereby driving the wind guide blade 122 connected to the first gear 1321 to rotate.

[0054] Specifically, the driving assembly 132 of this embodiment may include a first gear 1321, one end of which is connected to the output shaft of the driving motor 131, and the other end of which is connected to the wind guide blade 122. The driving motor 131 directly drives the first gear 1321 to rotate, thereby driving the wind guide blade 122 to rotate synchronously. In the air treatment device 100 of this embodiment, when the driving motor 131 drives the bottom plate 121 or the wind guide blade 122 to rotate, as long as the driving motor 131 starts to rotate, the wind guide blade 122 will inevitably rotate accordingly.

[0055] As a specific embodiment of the present invention, the first gear 1321 of this embodiment may further include a protrusion 1322. The driving assembly 132 may further include a second gear 1323, and the second gear 1323 is rotatably connected to the housing 110. The second gear 1323 may include at least one first slot 1324. When the first gear 1321 rotates, when the protrusion 1322 enters the first slot 1324, the second gear 1323 is driven to rotate, and when the protrusion 1322 comes out of the first slot 1324, the second gear 1323 does not move.

[0056] Specifically, in this embodiment, a protrusion 1322 is provided on the first gear 1321, and a first groove 1324 is provided on the second gear 1323. The protrusion 1322 and the first groove 1324 cooperate with each other, so that when the first gear 1321 rotates, the second gear 1323 can be driven to rotate in stages, and then the mechanism linked with the second gear 1323 can be driven to rotate in stages.

[0057] As a specific embodiment of the present invention, each driving assembly 132 of this embodiment may further include a third gear 1325, which is coaxially arranged with the first gear 1321 and rotates following the first gear 1321. The second gear 1323 has at least two grooves 1326, and the two grooves 1326 are located on both sides of the first groove body 1324. And the grooves 1326 contact the outer periphery of the third gear 1325 when the first groove body 1324 is separated from the protrusion 1322.

[0058] Specifically, in this embodiment, the position of the second gear 1323 can be limited by setting the third gear 1325 to contact the groove 1326, thereby limiting the position of the first groove body 1324 on the second gear 1323, thereby avoiding the misalignment of the first groove body 1324 and the protrusion 1322 on the first gear 1321, resulting in inability to cooperate with each other.

[0059] Specifically, the third gear 1325 may include a second slot body 1327 , and the second slot body 1327 is used to avoid the second gear 1323 when the protrusion 1322 enters the first slot body 1324 .

[0060] Specifically, the driving assembly 132 of this embodiment may include a third gear 1325 , and the second slot 1327 provided on the third gear 1325 may avoid the second gear 1323 to prevent the second gear 1323 from interfering with the third gear 1325 when being driven to rotate by the first gear 1321 .

[0061] As a specific embodiment of the present invention, the driving assembly 132 of this embodiment may further include a fourth gear 1328 . The fourth gear 1328 is coaxially arranged with the second gear 1323 and rotates following the second gear 1323 .

[0062] As a specific embodiment of the present invention, each driving assembly 132 of this embodiment may further include a fifth gear 1329, which is coaxially arranged with the first gear 1321. The fifth gear 1329 is meshed with the fourth gear 1328 to rotate under the drive of the fourth gear 1328. The fifth gear 1329 is connected to the bottom plate 121 to drive the bottom plate 121 to rotate when the fifth gear 1329 rotates.

[0063] Each driving assembly 132 may include a fourth gear 1328 and a fifth gear 1329, and the rotation of the second gear 1323 is transmitted to the fifth gear 1329 through the fourth gear 1328, and the fifth gear 1329 is then connected to the bottom plate 121 to drive the bottom plate 121 to rotate. The first gear 1321 and the second gear 1323 cooperate with each other, resulting in the first gear 1321 and the second gear 1323 rotating in opposite directions, and because the fourth gear 1328 and the second gear 1323 rotate synchronously, the fifth gear 1329 is meshed with the fourth gear 1328, so the fifth gear 1329 eventually rotates in the opposite direction to the second gear 1323, thereby making the fifth gear 1329 and the first gear 1321 rotate in the same direction, and follow the second gear 1323 to rotate in stages, so that the final rotation direction of the bottom plate 121 is the same as the rotation direction of the wind guide blades 122 on the bottom plate 121, and the bottom plate 121 rotates in stages. In addition, since the bottom plate 121 , the fifth gear 1329 and the first gear 1321 are all coaxially arranged, the wind guide blade 122 that finally rotates coaxially with the first gear 1321 can rotate coaxially with the bottom plate 121 .

[0064] As a specific embodiment of the present invention, in this embodiment, there are multiple air guide blades 122 at each bottom plate 121. The multiple air guide blades 122 are linked by a connecting rod, so that when one of the air guide blades 122 rotates in a controlled manner, the other air guide blades 122 rotate synchronously.

[0065] Specifically, the number of the air guide blades 122 of this embodiment is multiple, and the multiple air guide blades 122 are linked. When one of the air guide blades 122 is driven by the first gear 1321 to rotate, it can drive all the air guide blades 122 to rotate. The air guide blades 122 of this embodiment are linked by a connecting rod (not shown in the figure), and the multiple air guide blades 122 are parallel to each other or located in the same plane, and the rotation angles of the multiple air guide blades 122 are consistent.

[0066] As a specific embodiment of the present invention, a radially extending connecting arm (not shown in the figure) is provided at the rotation axis of each wind guide blade 122 of this embodiment, and the connecting arms at multiple wind guide blades 122 have the same length, one end of the connecting arm is connected to the rotation of the corresponding wind guide blade 122, and the other end is connected to the connecting rod. Specifically, a connecting arm is provided at each wind guide blade 122 of this embodiment, and the same length of all the connecting arms can ensure that the rotation angles of all the wind guide blades 122 are the same. In addition, when all the wind guide blades 122 are arranged in parallel, all the wind guide blades 122 rotate synchronously.

[0067] As a specific embodiment of the present invention, Figure 6 As shown, this embodiment provides a method for controlling the air outlet angle of an air treatment device 100, and the control method includes:

[0068] Step S100, based on the control instruction, determine whether the air outlet angle of the air guide mechanism 120 is greater than the preset angle; wherein the control instruction includes the air outlet angle; when the air outlet angle is less than or equal to the preset angle, execute step S200; when the air outlet angle is greater than the preset angle, execute step S300.

[0069] Step S200, controlling the driving motor 131 to drive the first gear 1321 to rotate from the initial position along the first preset direction, so as to drive the air guide blade 122 to rotate to the air outlet angle; wherein the initial position is the position of the first gear 1321 when the protrusion 1322 of the first gear 1321 is located at the opening position of the first slot 1324 of the second gear 1323;

[0070] In step S300, the driving motor 131 is controlled to drive the first gear 1321 to rotate from the initial position along the second preset direction, so as to drive the bottom plate 121 and the air guide blades 122 of the air guide mechanism 120 to rotate together to the air outlet angle; wherein the second preset direction is opposite to the first preset direction.

[0071] Specifically, in this embodiment, the driving mechanism 130 drives the driving component 132, and the driving component 132 then drives the base plate 121 and / or the air guide blades 122 to rotate. When the air outlet angle is small, it is only necessary to drive the air guide blades 122 to rotate to achieve the purpose of sweeping the air. When the air outlet angle is large, if only driving the air guide blades 122 to rotate cannot meet the requirements, the base plate 121 can be driven to rotate while driving the air guide blades 122 to rotate, thereby achieving the purpose of a large air sweeping angle.

[0072] As a specific embodiment of the present invention, the control method of this embodiment may also include:

[0073] When a shutdown command is received, the driving motor 131 is controlled to drive the first gear 1321 to rotate to an initial position.

[0074] Specifically, when the shutdown command is received, the first gear 1321 is driven to rotate to the initial position to ensure that the bottom plate 121 and the air guide blades 122 are restored to their original positions and are located in the housing 110, which is beneficial for the next drive. Specifically, when the first gear 1321 of the embodiment is in the initial position, the plurality of air guide blades are in the same plane, and the plane is perpendicular to the air outlet direction at the air outlet duct 111 of the housing 110.

[0075] Specifically, the control method and action steps of using a driving mechanism 130 to drive the corresponding bottom plate 121 and the air guide blades 122 located on the bottom plate 121 to rotate are as follows:

[0076] When the received output angle is greater than the preset angle, the state of the driving mechanism 131 is as follows: Figure 7 (a)- Figure 7 As shown in (d), the state of the wind guide blade 122 and the base 121 is as follows Figure 8 (a)- Figure 8 (d) is shown. The driving motor 131 drives the first gear 1321 to rotate counterclockwise from the initial position, and the wind guide blade 122 rotates counterclockwise following the first gear 1321. The first gear 1321 enters the first slot 1324 of the second gear 1323 through the protrusion 1322, thereby driving the second gear 1323 to rotate clockwise. At this time, the third gear 1325 rotates counterclockwise with the first gear 1321, and the second slot 1327 on the third gear 1325 gives way to the second gear 1323. The second gear 1323 drives the fourth gear 1328 to rotate clockwise, and the fourth gear 1328 drives the fifth gear 1329 to rotate counterclockwise, thereby causing the bottom plate 121 to rotate counterclockwise. At this time, the wind guide blade 122 and the bottom plate 121 both rotate counterclockwise. When the first gear 1321 continues to move counterclockwise under the drive motor 131 until the protrusion 1322 is separated from the first slot 1324, the second gear 1323 stops moving, and only the wind guide blade 122 rotates, while the bottom plate 121 does not rotate. During this movement, when the air outlet angle reaches the preset angle, the drive motor 131 is controlled to stop driving the first gear 1321 to rotate.

[0077] When the air outlet angle is less than the preset angle, the state of the driving mechanism 131 is as follows: Fig. 9 (a)- Fig. 9 As shown in (d), the state of the wind guide blade 122 and the base 121 is as follows Fig.10 (a)- Fig.10 (d). The driving motor 131 drives the first gear 1321 to rotate clockwise from the initial position, and the first gear 1321 drives the wind guide blade 122 to rotate clockwise. At this time, since the protrusion 1322 of the first gear 1321 is far away from the first slot 1324, the second gear 1323 will not be driven by the first gear 1321 to rotate. Since the third gear 1325 rotates clockwise with the first gear 1321, the outer periphery of the third gear 1325 and the groove 1326 of the second gear 1323 cooperate with each other, so that the second gear 1323 is immobile under the restriction of the third gear 1325 until the wind guide blade 122 rotates to the wind outlet angle, and the driving motor 131 is controlled to stop driving the first gear 1321 to move.

[0078] When a shutdown command is received, the above movements are reversed to restore to the initial state, ensuring that the bottom plate 121 and the air guide blades 122 are both located in the air outlet duct 111 of the shell 110, and the air guide blades 122 are located in the same plane to close the air outlet duct 111.

[0079] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
