Technical Field

[0001] This application relates to the field of electrical technology, and in particular to dehumidification devices. Background Technology

[0002] In the field of dehumidification equipment, to improve dehumidification efficiency, some existing solutions add adjustable airflow angle circulating fans to the air outlet. These fans typically have multi-directional motion capabilities, such as changing the pitch angle and height to expand the airflow coverage area, thereby accelerating the equalization of indoor humidity. However, the mechanical structure that realizes this complex motion function is often quite complex, resulting in a large overall module size, a significantly increased number of parts, and higher manufacturing costs.

[0073] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0074] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0075] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0076] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0077] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0078] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0079] See Figure 1 , Figure 2a and Figure 5a One embodiment of this application provides a dehumidification device including a housing 100, a fan module 200, and a drive module. See also... Figure 1 The housing 100 has an air inlet 111 and an air outlet 121. (See also...) Figure 1 and Figure 8 The fan module 200 includes a fan 210 and a fan driver 220 connected to each other. The fan 210 is located on the air outlet side of the air outlet 121, and the fan driver 220 is used to drive the fan 210 to rotate. (See reference...) Figures 2a to 2c ,as well as Figure 4 , Figure 5a and Figure 6a The drive module includes a flip assembly 300 rotatably connected to the housing 100, and a fan module 200 rotatably connected to the flip assembly 300. The flip assembly 300 includes a first drive member 310, which is used to drive the flip assembly 300 to rotate relative to the housing 100 and to simultaneously drive the fan module 200 to rotate relative to the flip assembly 300.

[0080] The dehumidification device in the above embodiment drives the flip assembly 300 to rotate relative to the housing 100 through a single first driving component 310, and simultaneously drives the fan module 200 to rotate relative to the flip assembly 300. While maintaining the multi-directional air delivery capability of the fan 210 (the flip assembly 300 rotates as a whole, and the fan module 200 rotates relative to the flip assembly 300 to coordinately adjust the air delivery angle), the mechanical structure is significantly simplified, the number of driving components and parts is reduced, thereby effectively reducing module complexity and manufacturing costs.

[0081] See Figure 5a and Figure 6aIn some embodiments, the flip assembly 300 includes a first transmission mechanism 330 and a second transmission mechanism 340. The first transmission mechanism 330 is tractively connected to the first drive member 310 and the fan module 200, and the second transmission mechanism 340 is tractively connected to the first drive member 310 and the housing 100. The first drive member 310 can drive the flip assembly 300 to rotate relative to the housing 100 through the second transmission mechanism 340, and can simultaneously drive the fan module 200 to rotate relative to the flip assembly 300 through the first transmission mechanism 330.

[0082] In the above embodiment, by setting up a dual transmission mechanism, the power output from the first drive component 310 is cleverly split. On one hand, the second transmission mechanism 340 drives the tilting component 300 to rotate relative to the housing 100 for pitch and height adjustment; on the other hand, the first transmission mechanism 330 drives the fan module 200 to rotate relative to the tilting component 300 for pitch and height adjustment. This integrated transmission design avoids the need for separate drive sources for the two movements, eliminates redundant structures, and makes the overall device more compact and economical.

[0083] In some embodiments, the transmission ratio of the power output from the first drive member 310 to the first transmission mechanism 330 is x, and the transmission ratio of the power output from the first drive member 310 to the second transmission mechanism 340 is y, where 2≤y / x≤6, and y / x is an integer.

[0084] In the above embodiment, by limiting the range of the transmission ratio y / x between the first drive member 310 outputting power to the first transmission mechanism 330 and the second transmission mechanism 340, a coordinated proportional relationship is maintained between the rotation angle of the fan module 200 relative to the flip assembly 300 and the rotation angle of the flip assembly 300 relative to the housing 100, so that the fan module 200 can rotate from the first drive member 310 to the second drive member 340. Figure 2a The horizontal folding state shown is raised to Figure 2b and Figure 2c Throughout the entire motion process at different angles, its rotation trajectory never interferes with the internal structure of the housing 100 or other components, thus ensuring the smoothness and reliability of the composite motion function.

[0085] Preferably, in some embodiments, the value of y / x is 2.

[0086] By further defining the transmission ratio y / x between the first drive unit 310 and the first transmission mechanism 330 and the second transmission mechanism 340 as a specific value (e.g., 2), the angular linkage between the fan module 200 and the flipping component 300 can be precisely locked, ensuring that both maintain a preset, interference-free motion trajectory during deployment. This specific transmission ratio not only optimizes motion coordination but also maximizes space utilization structurally, effectively avoiding the risk of mechanical collisions at specific angles and improving the overall reliability and stability of the motion.

[0087] In other embodiments, the value of y / x is 3, 4, 5, or 6.

[0088] See Figure 5a and Figure 6a In some embodiments, the flipping assembly 300 includes a flipping member 320, and a first driving member 310 is connected to the flipping member 320 and disposed inside the flipping member 320.

[0089] By setting the first driving component 310 inside the flipping component 320, the structural space of the flipping component 320 itself is fully utilized, and the built-in layout of the driving component is realized. This effectively reduces the extra space occupied by the flipping component 300 in the housing 100, making the overall structure more compact and the integration higher. This is beneficial for reducing the size of the dehumidification device and improving space utilization efficiency.

[0090] See Figure 2a ,as well as Figure 4 , Figure 5a and Figure 6a The drive module includes a first connecting component 400 connected to the housing 100. The flip component 300 includes a flip member 320 rotatably connected to the first connecting component 400. A first drive component 310 is mounted on the flip member 320. A first transmission mechanism 330, a second transmission mechanism 340, and a fan module 200 are all rotatably connected to the flip member 320. The second transmission mechanism 340 is drively connected between the first drive component 310 and the first connecting component 400. The first drive component 310 can drive the flip component 300 to rotate relative to the first connecting component 400 through the second transmission mechanism 340, and can simultaneously drive the fan module 200 to rotate relative to the flip component 320 through the first transmission mechanism 330.

[0091] The above embodiment, through a single first driving component 310 in conjunction with a linked flipping component 320, a first connecting assembly 400, and a dual transmission mechanism, maintains the multi-directional airflow capability of the fan 210 (the flipping assembly 300 rotates relative to the first connecting assembly 400, and the fan module 200 rotates relative to the flipping component 320, coordinating to adjust the airflow angle) while significantly simplifying the mechanical structure and reducing the number of driving components and parts, thereby effectively reducing module complexity and manufacturing costs. Specifically, the power output from the first driving component 310 is cleverly split: on the one hand, the second transmission mechanism 340 drives the flipping assembly 300 to adjust its pitch and height relative to the housing 100; on the other hand, the first transmission mechanism 330 drives the fan module 200 itself to adjust its pitch and height. This integrated transmission design avoids the need for separate drive sources for the two movements, eliminates redundant structures, and makes the overall device more compact and economical.

[0092] See Figure 2a , Figure 3 and Figure 4 In some embodiments, the housing 100 includes a side shell portion 110, a top shell portion 120, and a bottom shell portion 130, with the top shell portion 120 fixedly connected to the top end of the side shell portion 110. An air inlet 111 is disposed on the side shell portion 110, and an air outlet 121 is disposed on the top shell portion 120.

[0093] See Figure 2a ,as well as Figure 4 , Figure 5a and Figure 6a In some embodiments, the first transmission mechanism 330 is connected between the first drive member 310 and the fan module 200 via tooth meshing, and the second transmission mechanism 340 is connected between the first drive member 310 and the first connecting assembly 400 via tooth meshing.

[0094] Specifically, gear meshing transmission can be achieved by setting up gear sets. By limiting the first transmission mechanism 330 and the second transmission mechanism 340 to use gear meshing for transmission connection, the reliability and control accuracy of the overall mechanism are significantly improved. Gear meshing has advantages such as constant transmission ratio, high efficiency in power transmission, compact structure, and good rigidity. This not only ensures that the power output by the first drive component 310 can be accurately, synchronously, and without slippage transmitted to the tilting component 300 and the fan module 200 respectively, achieving stable and coordinated movement of the two, thereby accurately controlling the air delivery angle; at the same time, the meshing transmission structure itself is relatively simple and durable, further making the integrated composite motion mechanism more reliable and longer-lasting.

[0095] In other embodiments, the tooth meshing drive can be replaced by friction wheel drive, belt drive, or linkage drive, etc.

[0096] See Figure 5a , Figure 5b , Figure 6a and Figure 6b In some embodiments, the flipping assembly 300 includes a drive gear 350 connected to the first drive member 310, the first transmission mechanism 330 includes a first gear 331 rotatably connected to the flipping assembly 320, and the second transmission mechanism 340 includes a second gear 341 rotatably connected to the flipping assembly 320. Both the first gear 331 and the second gear 341 are meshed with the drive gear 350, and the first gear 331 is tractively connected to the fan module 200, while the second gear 341 is tractively connected to the first connecting assembly 400.

[0097] Specifically, the first driving member 310 is fixedly installed on the flipping member 320. The output shaft of the first driving member 310 is connected to the driving gear 350 to drive the driving gear 350 to rotate. The first gear 331 and the second gear 341 are both meshed with the driving gear 350. Therefore, when the driving gear 350 rotates, it will drive the first gear 331 and the second gear 341 meshed with it to rotate synchronously.

[0098] In the above embodiment, the first driving member 310 is directly connected to the drive gear 350, which simultaneously meshes with the first gear 331 and the second gear 341, further optimizing integration and transmission efficiency. This compact coplanar meshing design (both the first gear 331 and the second gear 341 directly mesh with the drive gear 350) simplifies the transmission chain, reduces intermediate transmission links and required installation space, making the overall structure simpler, more compact, and lighter. Simultaneously, the two driven gears (first gear 331 and second gear 341) share the same driving wheel (drive gear 350), ensuring the synchronization and stability of power distribution. This allows for precise coordination between the rotation of the fan module 200 and the overall rotation of the flipping assembly 300, improving the reliability and response speed of the airflow angle adjustment, and enhancing the cost and space advantages brought about by structural simplification.

[0099] See Figure 5a , Figure 5b , Figure 6a , Figure 6b , Figure 7 and Figure 8 In some embodiments, the first transmission mechanism 330 includes a third gear 332 coaxially connected to the first gear 331, and the fan module 200 includes a support 230 rotatably connected to the flipper 320. The support 230 has a first toothed portion 231, and the third gear 332 meshes with the first toothed portion 231.

[0100] Specifically, the fan module 200 includes a perforated fan housing 240, a fan drive component 220 fixedly mounted on the fan housing 240, and a fan 210 located inside the fan housing 240 and connected to the output shaft of the fan drive component 220. When the fan drive component 220 drives the fan 210 to rotate, airflow can pass through the perforated fan housing 240. A support base 230 is fixedly connected to the fan housing 240, and a first tooth 231 is provided at its end opposite to the fan housing 240. The support base 230 is rotatably connected to the flipping component 320 via a bearing. A third gear 332 is coaxially connected to the first gear 331, meaning that both are fixed on the same shaft. Therefore, they can rotate synchronously. When the third gear 332 rotates with the first gear 331, it will drive the support base 230 to rotate, thereby enabling the fan module 200 to rotate relative to the flipping component 320.

[0101] In the above embodiment, by setting a third gear 332 at the end of the first transmission chain and directly meshing it with the first tooth 231 on the support seat 230 of the fan module 200, efficient and compact power transmission from the tilting component 320 to the fan module 200 is achieved. This design significantly simplifies the transmission path of the pitch motion of the fan module 200 itself, reducing the number of parts and assembly complexity. At the same time, the meshing transmission between the third gear 332 and the first tooth 231 has the characteristics of good rigidity, precise transmission, and sensitive response, ensuring accurate and reliable control of the angle of rotation of the fan module 200 relative to the tilting component 320, and effectively transmitting torque and bearing load, thus enhancing the stability and durability of the overall mechanism.

[0102] In other embodiments, the third gear 332 may be omitted, and the first gear 331 may directly mesh with the first tooth portion 231. Alternatively, in other embodiments, other gears may be added between the third gear 332 and the first tooth portion 231 to indirectly achieve power transmission.

[0103] See Figure 5a , Figure 5d , Figure 6a , Figure 7 and Figure 8 In some embodiments, the support base 230 is provided with a torsion spring 232 connected to the flipping member 320. The torsion spring 232 is configured to drive the support base 230 to rotate relative to the flipping member 320 in a preset orientation by means of a rebound force.

[0104] Specifically, the flipping component 320 includes a flipping plate 321 and a flipping shell 322 fixedly connected. The flipping shell 322 covers the flipping plate 321, the first driving component 310, the driving gear 350, the first transmission mechanism 330, the second transmission mechanism 340, and other components. That is, the first driving component 310 is located inside the flipping shell 322. The support base 230 is rotatably connected to the flipping plate 321 via a bearing. The spring coil of the torsion spring 232 is sleeved on the support base 230, with one end pin connected to the support base 230 and the other end pin connected to the flipping plate 321. The first driving component 310 is fixedly installed on the flipping plate 321, and the first gear 331, the second gear 341, and the third gear 332 are all rotatably connected to the flipping plate 321. The preset orientation refers to the fan module 200 being in the position... Figure 2a The orientation at the horizontal angle shown.

[0105] like Figure 5d As shown, the flip shell 322 includes a first shell portion 3221 and a second shell portion 3222, which are connected by fixing screws.

[0106] In the above embodiments, when the drive stops or there is an unexpected power failure, the torsion spring 232 can automatically pull the fan module 200 back to its initial position (such as a horizontal angle), preventing the fan module 200 from accidentally drooping and hitting other components due to gravity, thereby improving the safety and reliability of the equipment.

[0107] See Figure 4 , Figure 5a , Figure 5c , Figure 6a and Figure 6b In some embodiments, the second transmission mechanism 340 includes a fourth gear 342 coaxially connected to the second gear 341, and the first connecting assembly 400 includes a connecting seat 410, a portion of the outer peripheral surface of the connecting seat 410 is provided with a second tooth portion 411, and the fourth gear 342 meshes with the second tooth portion 411.

[0108] Specifically, the connecting seat 410 is rotatably connected to the tilting plate 321 via a bearing, and the fourth gear 342 is also rotatably connected to the tilting plate 321. For example... Figure 5a and Figure 5d As shown, the flip-top shell 322 has a notch 3223 at the end of the connecting seat 410 opposite to the fourth gear 342, meaning that the connecting seat 410 is not completely covered by the flip-top shell 322. Figure 5a and Figure 5cAs shown, the fourth gear 342 is coaxially connected to the second gear 341, meaning they are both fixed on the same shaft. Therefore, they can rotate synchronously. When the fourth gear 342 rotates with the second gear 341, the connecting seat 410, being connected to the housing 100 and fixed in height relative to the housing 100, cannot rotate with the fourth gear 342. This causes the entire flip assembly 300 to rotate around the central axis of the connecting seat 410, thereby raising the position of the fan module 200. The flip shell 322 has a notch, primarily to allow for positional avoidance during the axial rotation of the entire flip assembly 300 around the connecting seat 410, preventing positional interference between the flip shell 322 and the connecting seat 410.

[0109] In the above embodiment, by having the fourth gear 342 at the end of the second transmission chain directly mesh with the second tooth portion 411 in a specific area on the outer circumferential surface of the connecting seat 410, a direct and efficient drive for the overall rotation of the flipping assembly 300 is achieved. This design transforms the connecting seat 410 itself into a transmission element, eliminating the need for additional complex linkage mechanisms, simplifying the structure, and reducing the number of parts. Furthermore, the partial tooth design (not full-circumferential teeth) of the connecting seat 410 ensures reliable meshing within the required rotational stroke while significantly reducing the weight of the connecting seat 410 and lowering its processing difficulty and cost. The meshing of the fourth gear 342 with the second tooth portion 411 provides advantages of high rigidity and precise transmission, ensuring accurate and reliable control of the rotation angle of the flipping assembly 300 relative to the housing 100 and effectively transmitting power, further strengthening the core advantages in structural simplification, compact layout, and cost control, while ensuring motion stability.

[0110] In other embodiments, the fourth gear 342 may be omitted, and the second gear 341 may directly mesh with the second tooth portion 411. Alternatively, in other embodiments, other gears may be added between the fourth gear 342 and the second tooth portion 411 to indirectly achieve power transmission.

[0111] See Figure 5a and Figure 6a In some embodiments, the first gear 331 and the second gear 341 are respectively disposed on both sides of the drive gear 350 along its own radial direction, and the rotation of the drive gear 350 can simultaneously drive the rotation of the first gear 331 and the second gear 341.

[0112] In the above embodiments, by arranging the first gear 331 and the second gear 341 on both sides of the drive gear 350 along its radial direction, the spatial layout and mechanical performance of the transmission structure are significantly optimized. This symmetrical or reasonably staggered distribution effectively utilizes the annular space around the drive gear 350, greatly compressing the volume of the overall transmission module, making the structure more compact, and is particularly beneficial for integration within the limited space inside the dehumidification device. At the same time, this layout helps to balance the radial force experienced by the drive gear 350 during meshing transmission, reducing gear bearing load and potential vibration, improving transmission smoothness, reducing operating noise, and extending the service life of the mechanism.

[0113] See Figures 2a to 2c ,as well as Figure 5a and Figure 6a The rotation axis of the flip assembly 300 relative to the first connecting assembly 400 is the A-axis, and the rotation axis of the fan module 200 relative to the flip member 320 is the B-axis. The A-axis and B-axis are parallel in space. Specifically, the B-axis is the central axis of the first gear 331 and the third gear 332, and the A-axis is the central axis of the connecting seat 410. Figure 2a In the position shown, both axis A and axis B are located in the horizontal plane and are parallel to one of the radial directions of the housing 100 (cylindrical).

[0114] When fan module 200 is in Figure 2a When the fan 210 is in the horizontal folded position (air outlet facing upwards), the rotational power output by the first drive member 310 drives the drive gear 350 to rotate counterclockwise, thereby driving the first gear 331 and the second gear 341 meshing with it to rotate clockwise. The third gear 332, which is coaxial with the first gear 331, and the fourth gear 342, which is coaxial with the second gear 341, also rotate clockwise synchronously. Since the fourth gear 342 meshes with the second tooth portion 411 provided on the outer peripheral surface of the connecting seat 410, and the connecting seat 410 is connected to the housing 100 (specifically, the connecting seat 410 is indirectly connected to the housing 100 through the rotating member 420, and the specific connection structure will be described in detail in the subsequent embodiments), the connecting seat 410 is fixed in the height direction relative to the housing 100. Therefore, the fourth gear 342 rotates clockwise around the trajectory of the second tooth portion 411, thereby causing the entire flip assembly 300 to rotate clockwise around the A-axis, realizing the lifting of the flip assembly 300 and the fan module 200. At the same time, since the third gear 332 meshes with the first tooth 231 provided on the connecting seat 230 in the fan module 200, when the third gear 332 rotates clockwise, it will drive the first tooth 231 that it is engaged with to rotate counterclockwise, thereby causing the entire fan module 200 to rotate counterclockwise relative to the flipping component 300.

[0115] by Figure 2a The position shown is the starting position, such as... Figure 2b As shown, when the flip assembly 300 rotates 45 degrees clockwise relative to the connecting seat 410 around axis A, the fan module 200 rotates 90 degrees counterclockwise relative to the flip assembly 300 around axis B. Figure 2c As shown, when the flip assembly 300 rotates 90 degrees clockwise around axis A relative to the connecting seat 410, the fan module 200 rotates 180 degrees counterclockwise around axis B relative to the flip assembly 300. This also matches the transmission ratio of 2 mentioned in the previous embodiment.

[0116] When fan module 200 is in Figure 2c In the vertically unfolded position shown (with the airflow outlet of fan 210 facing left), the rotational power output by the first drive member 310 drives the drive gear 350 to rotate clockwise, thereby causing the first gear 331 and the second gear 341 meshing with it to rotate counterclockwise. The third gear 332, which is coaxial with the first gear 331, and the fourth gear 342, which is coaxial with the second gear 341, also rotate counterclockwise synchronously. Since the fourth gear 342 meshes with the second tooth portion 411 provided on the outer peripheral surface of the connecting seat 410, and the connecting seat 410 is connected to the housing 100, the connecting seat 410 is fixed in the height direction relative to the housing 100. Therefore, the fourth gear 342 rotates counterclockwise around the trajectory of the second tooth portion 411, thereby causing the entire flip assembly 300 to rotate counterclockwise around the A-axis, realizing the lowering of the position of the flip assembly 300 and the fan module 200. At the same time, since the third gear 332 meshes with the first tooth 231 provided on the connecting seat 230 in the fan module 200, when the third gear 332 rotates counterclockwise, it will drive the first tooth 231 that it is engaged with to rotate clockwise, thereby causing the entire fan module 200 to rotate clockwise relative to the flipping component 300.

[0117] by Figure 2a The position shown is the starting position, such as... Figure 2b As shown, when the flip assembly 300 rotates 45 degrees counterclockwise around axis A relative to the connecting seat 410, the fan module 200 rotates 90 degrees clockwise around axis B relative to the flip assembly 300. Figure 2c As shown, when the flip assembly 300 rotates 90 degrees counterclockwise relative to the connecting seat 410 around axis A, the fan module 200 rotates 180 degrees clockwise relative to the flip assembly 300 around axis B.

[0118] See Figure 3 , Figure 4 , Figure 5a and Figure 9aIn some embodiments, the drive module includes a second connection component 500 fixedly connected to the housing 100. The first connection component 400 includes a rotating member 420 rotatably connected to the housing 100 and a second drive member 430 mounted on the rotating member 420. The second drive member 430 is throttlely connected to the second connection component 500 to drive the first connection component 400 to rotate relative to the second connection component 500.

[0119] Specifically, the rotating component 420 includes a rotating inner shell 421 and a rotating outer shell 422 fixedly connected (e.g., fixedly connected by screws). The rotating outer shell 422 is located outside the rotating inner shell 421, and the rotating inner shell 421 is fixedly connected to the connecting seat 410. The second connecting assembly 500 includes a fixedly connected bracket 520 and an impeller cover 530. The impeller cover 530 covers the outside of the impeller 610, and the bracket 520 is fixedly connected to the top shell portion 120. The rotating inner shell 421 is rotatably connected to the second connecting assembly 500 via a bearing 511, and thus indirectly rotatably connected to the housing 100.

[0120] In the above embodiments, by adding a second connecting component 500, a rotating component 420, and a second driving component 430, the first connecting component 400 (which in turn drives the entire flip component 300 and the fan module 200) is given the ability to rotate horizontally relative to the housing 100 around another axis (the vertical axis). This significantly expands the adjustable dimension of the airflow direction, enabling the fan 210 to perform omnidirectional adjustment of the horizontal azimuth angle on the basis of the original pitch adjustment, greatly improving the flexibility of airflow coverage and the efficiency of indoor humidity balance. The second connecting component 500 is fixed to the housing 100, and the second driving component 430 is directly installed on the rotating component 420 and drives the rotating component 420 to rotate relative to the second connecting component 500. This integrated design, while adding key degrees of freedom, maintains the directness of the transmission path, avoids introducing too many complex structures, effectively controls the complexity and space occupation of the added structure, and makes the realization of the three-dimensional airflow function more compact, efficient, and reliable.

[0121] See Figure 3 , Figure 4 , Figure 5a , Figure 9a and Figure 9b In some embodiments, the first connecting component 400 includes a fifth gear 440 connected to the second drive component 430, and the second connecting component 500 includes a sixth gear 510 fixedly connected to the housing 100, with the fifth gear 440 meshing with the sixth gear 510.

[0122] Specifically, the fifth gear 440 is connected to the output shaft of the second drive member 430 and is driven to rotate by the second drive member 430. In the second connecting assembly 500, the sixth gear 510 is fixedly connected to the bracket 520. The rotating member 420 is rotatably connected to the sixth gear 510 through the bearing 511. Since the sixth gear 510 is fixed in position relative to the housing 100 and cannot rotate, when the second drive member 430 drives the fifth gear 440 to rotate, the entire first connecting assembly 400, including the fifth gear 440, will rotate relative to the sixth gear 510, thereby driving the entire tilting assembly 300 and the fan module 200 to rotate horizontally.

[0123] In the above embodiment, the direct meshing of the fifth gear 440 and the sixth gear 510 fixed to the housing enables the second drive component 430 to drive the first connecting assembly 400 (and the entire tilting assembly 300 and fan module 200) to rotate horizontally. This design provides an extremely simple and rigid transmission path, reducing the number of intermediate transmission links and parts. The gear meshing ensures precise and reliable transmission, strong torque transmission capability, and accurate positioning, effectively supporting the precise adjustment of the horizontal airflow angle.

[0124] See Figure 9a , Figure 9b , Figure 9e and Figure 9f In some embodiments, in the rotating component 420, the rotating inner shell 421 is rotatably connected to the sixth gear 510 via the bearing 511, thereby achieving an indirect rotatable connection to the housing 100.

[0125] Specifically, the rotating inner housing 421 includes a downwardly extending cylindrical protrusion 4211, which is inserted into the sixth gear 510. The sixth gear 510 includes an upwardly protruding annular boss 512, and a bearing 511 is mounted between the outer wall of the protrusion 4211 and the inner wall of the boss 512. The rotating outer housing 422 has a central circular hole (20-32 mm in diameter), and the boss 512 extends into the central circular hole of the rotating outer housing 422.

[0126] As previously stated, the connecting base 410 is indirectly connected to the housing 100 via the rotating member 420. For details, please refer to... Figure 5a , Figure 5d , Figure 5e and Figure 9eIn some embodiments, the connecting seat 410 is fixedly connected to the rotating inner shell 421. For example, the bottom end of the connecting seat 410 is exposed through a notch 3223 provided on the flip shell 322 and is fixed to the rotating inner shell 421 by screws. Since the rotating inner shell 421 can only rotate horizontally relative to the sixth gear 510 (around the C-axis), the connecting seat 410 can only rotate horizontally with the rotating inner shell 421. Therefore, when the aforementioned fourth gear 342 rotates, the entire flip assembly 300 can rotate up and down around the central axis of the connecting seat 410 to achieve position raising and lowering.

[0127] See Figure 4 , Figure 5a , Figure 5d , Figure 5e , Figure 5f and Figure 6a In some embodiments, a through hole 4212 is provided on the rotating inner shell 421. The wire of the first driving member 310 is led out from the notch 3223, passes through the through hole 4212, and extends together with the wire of the second driving member 430 to be fixed in the wire-locking groove provided on the side of the sixth gear 510 (which is fixedly connected to the bracket 520 and does not move). Then it is fixed in the wire-locking groove provided on the middle rib of the bracket 520, and finally extends to the outside of the impeller cover 530, and then connects to the circuit board provided on the lower side of the impeller cover 530. Figure 5f The middle arrow indicates the direction of the conductor's extension.

[0128] See Figure 2a , Figure 2d and Figure 9a In some embodiments, the projections of the flip component 300 and the second drive component 430 onto the axis (B) in which the fan module 200 rotates relative to the flip component 300 at least partially overlap.

[0129] from Figure 9a It can be seen that there is an overlap between the positions of the second drive component 430 and the flip assembly 300 in the vertical direction. This allows for a compact arrangement of components, lowering the position of the flip assembly 300, thereby reducing the height of the top of the housing 100, i.e., lowering the height of the top housing 120, and thus increasing the distance H between the fan module 200 and the top housing 120. Figure 2d This makes it less likely for the fan module 200 to interfere with the top shell 120 during rotation.

[0130] See Figure 2a , Figure 3 , Figure 4 and Figure 5aIn some embodiments, the rotation axis A of the flip component 300 relative to the first connecting component 400 is parallel to the rotation axis B of the fan module 200 relative to the flip member 320; the rotation axis C of the first connecting component 400 relative to the second connecting component 500 is perpendicular to the rotation axis A of the flip component 300 relative to the first connecting component 400 in space.

[0131] Specifically, as described above, the rotation axis C of the first connecting assembly 400 relative to the second connecting assembly 500 extends vertically. The rotation axis A of the flipping assembly 300 relative to the first connecting assembly 400 and the rotation axis B of the fan module 200 relative to the flipping member 320 are both perpendicular to the vertical direction.

[0132] In the above embodiments, by explicitly defining that the rotation axis (A-axis) of the flipping component 300 relative to the first connecting component 400 is parallel to the rotation axis (B-axis) of the fan module 200 relative to the flipping component 320, and that the rotation axis (C-axis) of the first connecting component 400 relative to the second connecting component 500 is perpendicular to the A-axis, a clear, coordinated, and interference-free three-dimensional kinematic architecture is constructed. The parallel design of the A-axis and B-axis ensures that pitch adjustment (whether for the entire flipping component 300 or the fan module 200 itself) occurs within the same plane, significantly simplifying the layout and motion transmission of related transmission mechanisms (such as the first and second transmission mechanisms). The perpendicular relationship between the C-axis (horizontal rotation axis) and the A-axis naturally achieves the orthogonality between the pitch adjustment plane and the horizontal rotation plane, allowing the airflow direction to independently and collaboratively cover three-dimensional space, maximizing the airflow coverage. This optimized axis configuration ensures omnidirectional airflow capability while effectively avoiding internal interference during mechanism movement, reducing structural complexity, and improving the overall stability and reliability of the movement.

[0133] See Figure 4 , Figure 9a , Figure 9c and Figure 9d In some embodiments, one of the first connecting component 400 and the housing 100 has a roller 450 that rolls with the other.

[0134] Specifically, the top shell 120 is disposed around the outside of the rotating member 420. A plurality of circumferentially spaced rollers 450 are connected between the rotating inner shell 421 and the rotating outer shell 422. The rollers 450 roll in contact with the inner wall of the top shell 120. When the second driving member 430 drives the first connecting assembly 400 to rotate relative to the second connecting assembly 500, the rollers 450 will roll along the inner wall of the top shell 120. Alternatively, the rollers can also be mounted on the inner wall of the top shell 120 and roll along the outer wall of the rotating member 420.

[0135] In the above embodiment, the roller 450 efficiently converts the possible sliding friction into rolling friction, greatly reducing the rotational resistance torque. This not only makes the drive (the second drive component 430 driving the horizontal rotation) lighter, less strenuous, and less energy-consuming, but also improves the smoothness and response speed of angle adjustment. At the same time, rolling friction significantly reduces wear on the contact surface, extends the service life of related components, and enhances the long-term reliability of the mechanism.

[0136] Specifically, the roller 450 includes a roller shaft 451 and a roller sleeve 452. The roller shaft 451 is fixedly connected to the rotating housing 422. The roller sleeve 452 is sleeved on the roller shaft 451 and rotates with it. The roller sleeve 452 rolls with the inner wall of the top housing 120.

[0137] Furthermore, the rotating outer casing 422 is provided with an insertion hole 4221, into which the roller shaft 451 is inserted. The roller shaft 451 is a knurled shaft, and its position relative to the insertion hole 4221 remains fixed. The roller sleeve 452 and the inner wall of the top casing 120 have a concave-convex fit. For example, the circumferential surface of the roller sleeve 452 has a recessed structure, and the inner wall of the top casing 120 has a protruding structure that extends into the recessed structure. The roller sleeve 452 is preferably made of a wear-resistant material.

[0138] See Figure 1 , Figure 2a and Figure 3 In some embodiments, the dehumidification device includes an impeller 610 and an impeller drive 620 connected to each other. The impeller drive 620 drives the impeller 610 to rotate, so that airflow flows in through the air inlet 111 and is discharged through the air outlet 121, forming a negative pressure zone W between the air inlet 111 and the impeller 610. The dehumidification device includes a compressor 630, a condenser 640, and an evaporator 650. The condenser 640 and the evaporator 650 are disposed in the negative pressure zone W. The outer contour of the casing 100 is cylindrical. The condenser 640 surrounds at least a portion of the compressor 630, and the evaporator 650 surrounds at least a portion of the condenser 640.

[0139] Further, in the embodiment shown in the accompanying drawings, both the condenser 640 and the evaporator 650 are arc-shaped. The condenser 640 surrounds (semi-encloses) a portion of the compressor 630, and the evaporator 650 surrounds (semi-encloses) a portion of the condenser 640. Alternatively, in other embodiments, the condenser 640 and the evaporator 650 may also be U-shaped or L-shaped. Alternatively, in other embodiments, the condenser 640 and the evaporator 650 may also be annular, completely surrounding the outside of the compressor 630.

[0140] After compressor 630 starts, it compresses the gaseous refrigerant inside and pumps it into condenser 640, turning the refrigerant into a hot liquid. The refrigerant then enters evaporator 650 and expands into a gas, which then flows back to compressor 630. During this process, outside air flows in from inlet 111 under the suction of rotating impeller 610, passes through evaporator 650 and condenser 640 (both evaporator 650 and condenser 640 include many coiled coil tubes with gaps between them for air to pass through), then through impeller 610, and finally exits from outlet 121. The air is then distributed to the surrounding area by the rotation of fan 210. As the air passes through evaporator 650, moisture in it condenses upon contact with the condenser. The condensed water droplets fall below evaporator 650, achieving dehumidification. Finally, the dry air is distributed to the surrounding area by the rotation of fan 210, thereby reducing ambient humidity.

[0141] In the above embodiments, the outer contour of the casing 100 is cylindrical, and the shape design of the condenser 640 and evaporator 650 can better match the outer contour shape of the casing 100, improving space utilization and allowing key heat exchange components to be closely arranged in a high-efficiency airflow path. Secondly, the cylindrical shape combined with the nested structure greatly reduces the internal airflow dead angles. Under the negative pressure driven by the impeller 610, air can flow more evenly and smoothly through the evaporator 650 and condenser 640, significantly improving heat exchange efficiency and dehumidification capacity. Furthermore, this layout effectively shortens the duct length, reduces wind resistance and noise, and the compact cylindrical structure reduces the overall volume and floor space of the equipment, achieving a good balance between dehumidification performance, space efficiency and miniaturization.

[0142] See Figure 2a and Figure 3 In some embodiments, the dehumidification device includes a filter assembly 660 installed inside the housing 100 and disposed corresponding to the air inlet 111.

[0143] Specifically, the filter assembly 660 includes a first filter element 661 and a second filter element 662 arranged in sequence, with the second filter element 662 located on the side of the first filter element 661 facing away from the air inlet 111. After the outside airflow enters through the air inlet 111, it flows sequentially through the first filter element 661 and the second filter element 662 before passing through the evaporator 650 and the condenser 640, thus completing the air filtration and improving the air quality discharged from the air outlet 121. One of the first filter element 661 and the second filter element 662 is used to filter dust particles, and the other is used to filter harmful gases, etc.

[0144] Additionally, a perforated support grid 150 is provided between the filter assembly 660 and the evaporator 650. The bottom end of the support grid 150 is fixed to the bottom shell portion 130, and the top end is fixed to a horizontal plate connected to the side shell portion 110. The support grid 150 increases the strength of the housing 100. The aforementioned bottom shell portion 130 is fixed to the bottom end of the filter assembly 660.

[0145] See Figure 1 , Figure 2a and Figure 3 In some embodiments, the dehumidification device includes a water tray 710, a water pump 720, and a water tank 730 detachably mounted on the housing 100. The water tray 710 is located below the evaporator 650, and the water pump 720 is used to pump liquid on the water tray 710 into the water tank 730.

[0146] Specifically, the drip tray 710 is fixedly installed on the bottom shell 130. When air passes through the evaporator 650, the moisture in it condenses upon cooling, and the condensed water droplets fall into the drip tray 710 below the evaporator 650. A water pump 720 pumps the liquid from the drip tray 710 into the water tank 730. The water tank 730 is equipped with a level sensor; when the water level reaches the upper limit, it indicates that the tank is full. Thus, the water can be emptied by lifting the tank 730, which is more convenient than removing the drip tray 710 to empty it.

[0147] See Figure 1 , Figure 2a and Figure 3 In some embodiments, the dehumidification device includes a water tank base 740 connected to one side of the housing 100, a water pump 720 installed inside the water tank base 740, and a water tank 730 detachably installed in the water tank base 740.

[0148] Specifically, the water tank 730 is detachably mounted vertically to the water tank base 740. The water tank base 740 is fixedly mounted on one side of the side shell 110, and the water tank 730 is detachably mounted above the water tank base 740. When there is a large amount of water in the water tank 730, it can be lifted upwards to separate from the water tank base 740, and the water can be poured out. Because the water tank 730 is detachably mounted vertically to the water tank base 740, it is more convenient, less strenuous, and less prone to spillage when emptying the water.

[0149] See Figure 1 , Figure 2a and Figure 3 In some embodiments, the bottom end of the water tank 730 is provided with a mounting ring 731, which is sleeved on the water tank seat 740 with a clearance fit. With this arrangement, when installing the water tank 730, the mounting ring 731 and the top end of the water tank seat 740 cooperate to provide quick guidance and positioning, making installation easier.

[0150] See Figure 1 , Figure 2a and Figure 3 ,as well as Figure 10a In some embodiments, the water tank 730 has an inlet 732 at its bottom end, a first valve 750 is installed at the inlet 732, and a second valve 760 is installed at the top of the water tank seat 740. When the water tank 730 is installed on the water tank seat 740, the first valve 750 and the second valve 760 are connected to conduct water between the water tank 730 and the water pump 720. When the water tank 730 and the water tank seat 740 are separated, the first valve 750 closes the inlet 732, and the second valve 760 disconnects the flow path between the water tank 730 and the water pump 720.

[0151] In the above embodiments, the dual-valve structure reduces the risk of accidental condensate leakage during the installation or removal of the water tank 730, keeping the equipment and surrounding environment dry and clean. Simultaneously, the automatic opening and closing function eliminates the need for additional valve operation by the user, simplifying the water tank placement and removal process and improving the user experience. When the water tank 730 and the water tank base 740 are separated, the dual valves close to prevent dust and contaminants from entering the piping system, ensuring pipe cleanliness and preventing the water pump 720 from drawing water from the drip tray 710 and causing leakage outside the water tank base 740.

[0152] Further, see Figures 10a to 10c In some embodiments, the second valve 760 includes a valve pipe 762 and a plugging portion 761 extending into and elastically connected to the valve pipe 762. The valve pipe 762 has an outlet 7621 communicating with the water pump 720. The first valve 750 includes a pushing portion 751 elastically connected to the water tank 730. When the water tank 730 and the water tank seat 740 are separated, the plugging portion 761 blocks the outlet 7621 under the action of elastic force, and the pushing portion 751 blocks the inlet 732 under the action of elasticity. When the water tank 730 is installed on the water tank seat 740, the pushing portion 751 and the plugging portion 761 push against each other to separate the plugging portion 761 from the outlet 7621 and the pushing portion 751 from the inlet 732.

[0153] Furthermore, in some embodiments, the first valve 750 includes a valve cap 753 and a first elastic member 752, the valve cap 753 being connected to the water tank 730, and the first elastic member 752 being connected to the valve cap 753 and the push portion 751; the second valve 760 includes a second elastic member 763, the second elastic member 763 being connected to the sealing portion 761 and the valve pipe 762;

[0154] When the water tank 730 and the water tank base 740 are separated, the second elastic member 763 uses elastic force to (e.g., pull) the sealing part 761 to seal the water outlet 7621, and the first elastic member 752 uses elastic force to (e.g., push) the pushing part 751 to seal the water inlet 732.

[0155] Specifically, the first valve 750 further includes a sleeve 755, which is fixedly installed inside the inlet 732. A valve cap 753 is fixedly installed inside the sleeve 755. The top end of the push part 751 is inserted into the valve cap 753. A first elastic element 752 (spring) is sleeved on the outside of the push part 751, with its two ends abutting against the push part 751 and the valve cap 753 respectively. A first sealing element 754 is also embedded on the outer side of the bottom portion of the push part 751. In the second valve 760, the valve pipe 762 is hollow inside, and its bottom end forms an outlet 7621 connected to the water pump 720. The sealing part 761 includes a sealing rod 7611 and a sealing sleeve 7612. The sealing rod 7611 is inserted into the valve pipe 762, and the sealing sleeve 7612 is sleeved on the outside of the bottom portion of the sealing rod 7611. The sealing sleeve 7612 is preferably made of a flexible material (e.g., rubber or silicone). The second elastic element 763 (spring) is sleeved on the outside of the sealing rod 7611, and its two ends abut against the stepped surface on the sealing rod 7611 and the stepped surface on the inner wall of the valve pipe 762, respectively.

[0156] When the water tank 730 and the water tank base 740 are separated, the rebound force of the first elastic element 752 will push the pushing part 751 downward, thereby blocking the bottom opening of the sleeve 755, and thus indirectly blocking the water inlet 732. When the water tank 730 is installed on the water tank base 740, the rebound force of the second elastic element 763 will push the sealing rod 7611 upward, thereby allowing the sealing sleeve 7612 to block the water outlet 7621.

[0157] When the water tank 730 is installed on the water tank base 740, the sealing part 761 pushes the pushing part 751 upwards, thereby separating the pushing part 751 from the water inlet 732. At the same time, the pushing part 751 pushes the sealing part 761 downwards, thereby separating the sealing part 761 from the water outlet 7621. At this time, the first elastic member 752 is compressed and deformed, and the second elastic member 763 is compressed and deformed.

[0158] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
