[0038] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0039] This application provides an air guiding device, such as... Figures 1 to 18 As shown, the air guiding device includes a bracket 100 with an air outlet 110 and an air guiding mechanism 200 mounted on the bracket 100. The air guiding mechanism 200 includes a drive assembly 210, a connecting shaft 220, and multiple air guiding plates 230. The multiple air guiding plates 230 are rotatably mounted on the air outlet 110 and arranged in the vertical direction. The air guiding plates 230 are provided with internal toothed holes 231. The connecting shaft 220 passes through the internal toothed holes 231 of the multiple air guiding plates 230. The drive assembly 210 can drive the connecting shaft 220 to move in the vertical direction while rotating. Multiple linkage gears 240 are sleeved on the connecting shaft 220. The multiple linkage gears 240 are arranged sequentially in the vertical direction and can mesh with the internal toothed holes 231 of the multiple air guiding plates 230 one by one. The distance between two adjacent linkage gears 240 is smaller than the distance between the internal toothed holes 231 of two adjacent air guiding plates 230.

[0040] Among them, the axial direction of the internal tooth hole 231 and the axial direction of the connecting shaft 220 are both parallel to the vertical direction; "the distance between the internal tooth holes 231 on two adjacent air guide plates 230" refers to the center distance between the internal tooth holes 231 on two adjacent air guide plates 230; "the distance between two adjacent linkage gears 240" refers to the distance between the same end face of two adjacent linkage gears 240, such as the distance between the upper end face of two adjacent linkage gears 240, or the distance between the lower end face of two adjacent linkage gears 240.

[0041] The air guiding device provided in this application embodiment has multiple air guiding plates 230 arranged in the vertical direction. The driving component 210 can drive the connecting shaft 220 to rotate and move in the vertical direction at the same time. Multiple linkage gears 240 arranged in the vertical direction are sleeved on the connecting shaft 220. The connecting shaft 220 passes through the internal tooth holes 231 of the multiple air guiding plates 230, and the multiple linkage gears 240 can mesh with the internal tooth holes 231 of the multiple air guiding plates 230 one-to-one. The distance between two adjacent linkage gears 240 is smaller than the distance between the internal tooth holes 231 of two adjacent air guiding plates 230. Therefore, during the process of the connecting shaft 220 rotating and moving in the vertical direction at the same time, the multiple air guiding plates 230 can rotate intermittently in segments. This can make the air supply direction more diverse, expand the air supply angle, realize the whole-area air supply mode, and thus improve the user experience.

[0042] Understandably, since the distance between two adjacent linkage gears 240 is smaller than the distance between the internal tooth holes 231 on two adjacent air guide plates 230, the intermittent rotation of multiple air guide plates 230 can be achieved by utilizing the time difference between the engagement of multiple linkage gears 240 on the connecting shaft 220 and the internal tooth holes 231 on multiple air guide plates 230. This transforms the existing integrated air sweeping into intermittent air sweeping by multiple air guide plates 230, enriching the air delivery direction and expanding the air delivery angle, achieving a full-area air delivery mode, and improving the user experience. Furthermore, by disassembling the existing integrated air guide plate 230 into multiple air guide plates 230 arranged in the vertical direction, each air guide plate 230 can be individually disassembled and replaced. This avoids the problem of replacing the entire component when the integrated air guide plate 230 is damaged, thereby reducing costs and improving efficiency.

[0043] In some embodiments of this application, the air guiding mechanism 200 is configured such that when the middle part of the linkage gear 240 located at the rear end of the moving direction of the connecting shaft 220 meshes with the corresponding internal tooth hole 231, the linkage gear 240 located at the front end of the moving direction of the connecting shaft 220 begins to mesh with the corresponding internal tooth hole 231. This allows for more effective control of the intermittent rotation of multiple air guide plates 230, achieving the effect of intermittent sweeping and air delivery without dead zones.

[0044] For ease of understanding, the gear 240 located at the rear end of the connecting shaft 220 in the moving direction can be defined as the first gear, and the gear 240 located at the front end of the connecting shaft 220 in the moving direction can be defined as the second gear. The air guide mechanism 200 is configured such that, during the rotation of the connecting shaft 220 and its simultaneous movement in the up and down direction, the second gear only begins to mesh with the corresponding internal tooth hole 231 when the middle part of the first gear 240 meshes with the corresponding internal tooth hole 231.

[0045] For example, in combination Figure 1 , Figure 3 , Figure 5 , Figure 8 , Figure 9 , Figure 11 and Figure 12 As shown, the air guiding mechanism 200 includes three air guiding plates 230, which are, from top to bottom, an upper air guiding plate 230a, a middle air guiding plate 230b, and a lower air guiding plate 230c. Three linkage gears 240 are provided on the connecting shaft 220, which are, from top to bottom, an upper linkage gear 240a, a middle linkage gear 240b, and a lower linkage gear 240c. The upper linkage gear 240a, middle linkage gear 240b, and lower linkage gear 240c respectively engage with the internal toothed holes 231 on the upper air guiding plate 230a, middle air guiding plate 230b, and lower air guiding plate 230c, and the engagement timing is different: during the rotation of the connecting shaft 220 and its simultaneous downward movement, the internal toothed hole 231 on the upper air guiding plate 230a first engages with the lower end of the upper linkage gear 240a, and the connecting shaft 220 moves downwards... When the connecting shaft 220 moves downward to the middle position of the upper linkage gear 240a and engages with the internal tooth hole 231 on the upper guide plate 230a, the lower end of the middle linkage gear 240b begins to engage with the internal tooth hole 231 on the middle guide plate 230b. When the connecting shaft 220 moves downward to the upper end of the upper linkage gear 240a and engages with the internal tooth hole 231 on the upper guide plate 230a, the middle position of the middle linkage gear 240b engages with the internal tooth hole 231 on the middle guide plate 230b. At this time, the lower end of the lower linkage gear 240c begins to engage with the internal tooth hole 231 on the lower guide plate 230c, thereby realizing the intermittent rotation of the three guide plates 230. When the connecting shaft 220 rotates and moves upward at the same time, the movement sequence is reversed, that is, the lower guide plate 230c rotates first, then the middle guide plate 230b rotates, and finally the upper guide plate 230a rotates.

[0046] In some embodiments of this application, such as Figure 13 As shown, the linkage gear 240 includes a meshing portion 241 and two guide portions 242. One guide portion 242, the meshing portion 241, and the other guide portion 242 are connected sequentially in the vertical direction, that is, the two guide portions 242 are respectively connected to the two ends of the meshing portion 241 in the vertical direction. The meshing portion 241 is used to mesh with the corresponding internal tooth hole 231. The outer diameter of both guide portions 242 gradually decreases in the direction away from the meshing portion 241. The distance between the meshing portions 241 of two adjacent linkage gears 240 is smaller than the distance between the internal tooth holes 231 on two adjacent air guide plates 230. By providing guide portions 242 at both ends of the meshing portion 241 in the vertical direction, the linkage gear 240 can more easily enter the corresponding internal tooth hole 231 during the vertical movement with the connecting shaft 220.

[0047] In some embodiments of this application, such as Figures 15-17 As shown, the air guide plate 230 includes an air guide plate body 232 and a first connecting plate 233. The air guide plate body 232 has an air guiding surface and a leeward surface. The first connecting plate 233 is disposed on the air guiding surface, and an internal toothed hole 231 is formed on the first connecting plate 233. It can be understood that the air guiding surface of the air guide plate body 232 faces the airflow, and the leeward surface faces away from the airflow. By providing the first connecting plate 233 on the air guiding surface of the air guide plate body 232 and forming the internal toothed hole 231 on the first connecting plate 233, the assembly of the air guide plate 230 and the connecting shaft 220 is facilitated, and the structural strength of the air guide plate body 232 is avoided by directly drilling holes in it.

[0048] Optionally, the air guide plate 230 further includes a reinforcing plate 234 and two second connecting plates 235. The reinforcing plate 234 is located on the air guide side of the air guide plate body 232, and the two ends of the air guide plate body 232 are connected to the two ends of the reinforcing plate 234 respectively through the two second connecting plates 235. The connecting shaft 220 passes through at least one second connecting plate 235, and the first connecting plate 233 is located between the two second connecting plates 235 and connected to the reinforcing plate 234. By setting the reinforcing plate 234 and the second connecting plates 235, the balance of the air guide plate 230 during rotation can be improved, avoiding noise and uneven air delivery caused by the shaking of the air guide plate 230 during rotation.

[0049] For example, when there are two air guide plates 230, the two air guide plates 230 are defined as upper air guide plate 230a and lower air guide plate 230c, respectively. The connecting shaft 220 can pass through the two second connecting plates 235 of the upper air guide plate 230a, and also through a connecting plate of the lower air guide plate 230c near the upper air guide plate 230a. When there are three air guide plates 230, the three air guide plates 230 are defined as upper air guide plate 230a, middle air guide plate 230b and lower air guide plate 230c, respectively. The connecting shaft 220 passes through the two second connecting plates 235 of the upper air guide plate 230a and the two second connecting plates 235 of the middle air guide plate 230b, and also through a second connecting plate 235 of the lower air guide plate 230c near the end of the middle air guide plate 230b.

[0050] Optionally, the air guide plate 230 also includes a third connecting plate 236, which is located between the two second connecting plates 235. The third connecting plate 236 is positioned close to the first connecting plate 233 and connected to the reinforcing plate 234. By providing the third connecting plate 236, the structural strength of the air guide plate 230 can be further improved, preventing deformation of the air guide plate 230 and ensuring precise control of the airflow.

[0051] It is understandable that mounting through holes 237 can be opened on both the second connecting plate 235 and the third connecting plate 236, so that the connecting shaft 220 can be directly inserted into the mounting through holes 237 when it is connected and assembled with the second connecting plate 235 and the third connecting plate 236, thereby improving the assembly efficiency of the connecting shaft 220 with the second connecting plate 235 and the third connecting plate 236.

[0052] In some embodiments of this application, combined with Figure 6 , Figures 8-11 and Figure 14 As shown, the drive assembly 210 includes a drive member 211 and a drive gear 212. The drive member 211 can drive the drive gear 212 to rotate about an axis parallel to the vertical direction. One end of the connecting shaft 220 is provided with a driven tooth portion 221 and a helical tooth portion 222. The driven tooth portion 221 is arranged circumferentially along the connecting shaft 220, and the helical tooth portion 222 is arranged on the outer periphery of the driven tooth portion 221 and extends helically in the vertical direction. The drive gear 212 partially extends into one of the tooth grooves 223 of the helical tooth portion 222 and meshes with the driven tooth portion 221. In this way, the drive assembly 210 can drive the connecting shaft 220 to move in the vertical direction while rotating.

[0053] For example, such as Figure 10 As shown, when the driving member 211 drives the driving gear 212 to rotate counterclockwise, since the driving gear 212 meshes with the driven teeth 221 on the connecting shaft 220, the counterclockwise rotation of the driving gear 212 will drive the connecting shaft 220 to rotate clockwise. Because part of the driving gear 212 extends into the tooth groove 223 of the helical teeth 222 on the connecting shaft 220, the connecting shaft 220 will move downwards while rotating clockwise; during the downward movement of the connecting shaft 220... During the process, the upper linkage gear 240a first meshes with the internal toothed hole 231 on the upper air guide plate 230a to make the upper air guide plate 230a rotate. Then, the middle linkage gear 240b meshes with the internal toothed hole 231 on the middle air guide plate 230b to make the middle air guide plate 230b rotate. Finally, the lower linkage gear 240c meshes with the internal toothed hole 231 on the lower air guide plate 230c to make the lower air guide plate 230c rotate, thereby achieving the effect of segmented intermittent rotation of the three air guide plates 230 (e.g., Figure 3 As shown, Figure 3 The dashed arrows in the image indicate airflow.

[0054] Similarly, when the driving component 211 drives the driving gear 212 to rotate clockwise, since the driving gear 212 meshes with the driven teeth 221 on the connecting shaft 220, the clockwise rotation of the driving gear 212 will drive the connecting shaft 220 to rotate counterclockwise. Since part of the driving gear 212 extends into the tooth groove 223 of the helical teeth 222 on the connecting shaft 220, the connecting shaft 220 will move upward while rotating counterclockwise. During the upward movement of the connecting shaft 220, the lower linkage gear 240c will first mesh with the internal tooth hole 231 on the lower air guide plate 230c to make the lower air guide plate 230c rotate. Then, the middle linkage gear 240b will mesh with the internal tooth hole 231 on the middle air guide plate 230b to make the middle air guide plate 230b rotate. Finally, the upper linkage gear 240a will mesh with the internal tooth hole 231 on the upper air guide plate 230a to make the upper air guide plate 230a rotate.

[0055] Optionally, the driving component 211 is a motor, which is mounted on the top of the bracket 100, and the driving gear 212 is sleeved on the motor shaft. By driving the driving gear 212 to rotate forward and reverse, the rotation direction and movement direction of the connecting shaft 220 can be easily controlled.

[0056] In some embodiments of this application, such as Figure 1 and Figure 3 As shown, the bracket 100 has air outlets 110 and air guide mechanisms 200 on both the left and right sides, with the air guide mechanisms 200 on both sides corresponding one-to-one with the air outlets 110 on both sides. In this way, the air supply modes can be further enriched, the air supply angle can be expanded and air supply without dead angles can be achieved, thereby further improving the user experience.

The specific structure of the air guide device is as described in the above embodiments. The air guide device is installed on the casing, and an air duct is formed inside the casing. The air duct is connected to the air outlet 110 of the air guide device. Since this cabinet air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
