[0036] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0039] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if the meaning of "and / or" appearing in the full text is to include three parallel schemes, taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0040] An air handling device typically has multiple different operating gears, and the air outlet direction changes when the operating gear is switched. For example, the air handling device has three operating gears, namely, gear 1, gear 2, and gear 3. When the air handling device is in gear 1, the fan of the air handling device tends to blow air toward the left side of the air outlet 110; when the air handling device is in gear 2, the fan of the air handling device tends to blow air toward the center of the air outlet 110; when the air handling device is in gear 3, the fan of the air handling device tends to blow air toward the right side of the air outlet 110. That is, the three operating gears of the air handling device correspond to air outlet directions toward the left side, center, and right side of the air outlet 110, respectively, and the three operating gears correspond to three air outlet directions.

[0041] A traditional air treatment device is provided with an air outlet on its air outlet frame, and an air outlet grille is provided at the air outlet. The air outlet grille is fixedly connected to the air outlet frame, and the air outlet grille and the air outlet frame are integrally formed, so that the angle of the air outlet grille cannot be adjusted. Such a setting makes it impossible for the air outlet grille to adaptively adjust its angle as the air outlet direction changes, and the air outlet grille will block the air outlet airflow of one or more gears, thereby affecting the circulation of the airflow.

[0042] In order to solve the above problems, the present invention proposes an air outlet component 10 and an air treatment device 20 including the air outlet component 10. The air outlet component 10 can improve the smoothness of the air flow at the air outlet 110, avoid the air outlet grille in the traditional air treatment device from affecting the circulation of the air flow, thereby improving the applicability of the air treatment device.

[0043] See also Figures 1 to 3 In one embodiment of the present invention, the air outlet assembly 10 includes an air outlet frame 100, an air guide plate 200 and a limiting member 300. The air outlet frame 100 is provided with an air outlet 110; the air guide plate 200 is rotatably mounted on the air outlet 110, and the air guide plate 200 is adapted to be driven to rotate by the air flow blown out of the air outlet 110; the limiting member 300 is provided on one side of the air guide plate 200, so as to abut against the air guide plate 200 and limit the position of the air guide plate 200 when the air guide plate 200 rotates until its air guide surface is consistent with the flow direction of the air flow.

[0044] It is understood that the air guide plate 200 has an air guide surface, which is the outer wall surface of the air guide plate 200. The air guide surface can guide the airflow blown out of the air outlet 110, so that the airflow can be blown out of the air outlet 110 along the air guide surface of the air guide plate 200. The air guide plate 200 can be provided with a rotating shaft 220. The air outlet 110 of the air outlet frame 100 is provided with an axial hole 130 that is compatible with the rotating shaft 220. The rotating shaft 220 is inserted into the axial hole 130, so that the air guide plate 200 is rotatably mounted at the air outlet 110. In this embodiment, the air guide plate 200 is provided with a rotating shaft 220 at both ends along its length direction. The air outlet 110 of the air outlet frame 100 is provided with an axial hole 130 that is compatible with the two rotating shafts 220. This arrangement improves the stability of the air guide plate 200 in rotation at the air outlet 110.

[0045] Furthermore, the air deflector 200 in this embodiment rotates driven by the outlet airflow, meaning that the flow direction of the outlet airflow affects the rotation direction of the air deflector 200. For ease of explanation, the air deflector 200 is arranged in the height direction, and the air outlet 110 is arranged directly in front. For example, when the outlet airflow blows toward the left side of the air outlet 110, the air deflector 200 tends to rotate clockwise around the rotation axis 220; when the outlet airflow blows toward the right side of the air outlet 110, the air deflector 200 tends to rotate counterclockwise around the rotation axis 220. Of course, in other embodiments, the flow direction of the outlet air flow can be blown toward the top of the air outlet 110, or the flow direction of the outlet air flow can be blown toward the bottom of the air outlet 110. At this time, the air guide plate 200 can be set in the horizontal direction, or the air guide plate 200 can be set at an angle to the horizontal direction so that the rotation direction of the air guide plate 200 is adapted to the flow direction of the outlet air flow. The specific arrangement direction of the air guide plate 200 is not limited.

[0046] Furthermore, the position limiting member 300 is used to limit the position of the air guide plate 200 so that the air guide plate 200 stops rotating when it rotates to the direction in which the air flow is in line with the flow direction of the air flow. The position limiting member 300 abuts against the air guide plate 200 to limit the position of the air guide plate 200 so that the air guide plate 200 does not rotate. At this time, the position of the air guide plate 200 is adapted to the flow direction of the air flow, reducing the obstruction of the air guide plate 200 to the air flow, thereby facilitating the air flow to flow along the air guide plate 200. Blown out to the outside of the air outlet 110, that is, the position where the air guide plate 200 is limited by the limiting member 300 after rotation is the optimal position for guiding the air. The flow directions of different airflows correspond to different positions. The air guide plate 200 of this solution cooperates with the limiting member 300 to realize the adaptive adjustment of the rotation direction of the air guide plate 200 along with the flow direction of the airflow, so as to ensure the smoothness of the airflow at the air outlet 110, thereby making the air volume of the air blown out from the air outlet 110 larger.

[0047] When the flow direction of the outlet air flow changes, the air guide plate 200 can rotate with the drive of the air flow and rotate again to be consistent with the changed flow direction of the outlet air flow. The limiter 300 can adaptively adjust the position of the air guide plate 200 with the rotation of the air guide plate 200. The structure of the limiter 300 is not specifically limited, for example but not limited to: the limiter 300 is elastic, and the limiter 300 can adaptively move elastically with the rotation of the air guide plate 200 to limit the position of the air guide plate 200; or, the limiter 300 is connected by an elastic member, and the elastic member can drive the limiter 300 to move, so that the limiter 300 can move in cooperation with the elastic member with the rotation of the air guide plate 200, thereby limiting the position of the air guide plate 200, and the elastic member can be reset, so that after the flow direction of the outlet air flow changes, the air guide plate 200 can rotate again with the drive of the air flow.

[0048] The air outlet assembly 10 of this scheme includes an air outlet frame 100, an air guide plate 200 and a limiting member 300. The air outlet frame 100 is provided with an air outlet 110, and the air guide plate 200 is rotatably installed on the air outlet 110. The air guide plate 200 is suitable for being driven to rotate by the air flow blown out of the air outlet 110. The limiting member 300 is provided on one side of the air guide plate 200, so as to abut against the air guide plate 200 and limit the position of the air guide plate 200 when the air guide plate 200 is rotated until its air guide surface is consistent with the flow direction of the air flow. With such a configuration, with the cooperation of the limiting member 300, the rotation direction of the air guide plate 200 can be adaptively adjusted according to the flow direction of the air flow, so as to ensure that the air guide plate 200 can guide the air flow blown out from the air outlet 110, so as to increase the air volume, thereby improving the smoothness of the air flow at the air outlet 110.

[0049] In one embodiment, there are multiple air guide plates 200, and the multiple air guide plates 200 are arranged in sequence at intervals. The multiple air guide plates 200 are all provided with the limiting member 300 on the same side, so that the air guide plates 200 are arranged correspondingly to the limiting member 300. It is understood that the multiple air guide plates 200 are arranged in sequence at intervals, which is conducive to guiding the outgoing air flow in sequence. The multiple air guide plates 200 are all provided with the limiting member 300 on the same side, that is, there are multiple limiting members 300, and the multiple limiting members 300 can be provided on the same side of the multiple air guide plates 200. Of course, the multiple limiting members 300 can also be provided on opposite sides of the multiple limiting members 300.

[0050] That is, a limit member 300 is provided on one side of each air deflector 200, and the limit member 300 limits the rotational position of the air deflector 200 on one side of the air deflector 200; alternatively, a limit member 300 is provided on both sides of each air deflector 200, and the limit members 300 limit the rotational position of the air deflector 200 on opposite sides of the air deflector 200. As for the number of limit members 300, there is no limit, and it is only necessary that the limit members 300 are provided in correspondence with the air deflectors 200. This solution, by providing multiple air deflectors 200 and multiple limit members, and the limit members 300 correspondingly cooperate with the air deflectors 200, can fully guide the outgoing airflow, thereby facilitating smoother circulation of the outgoing airflow.

[0051] See also Figures 2 to 4 In one embodiment, the limiting member 300 includes a limiting block 310 and a reset member 320. The limiting block 310 is movably installed on the air outlet frame 100 along the length direction of the air guide plate 200. The limiting block 310 can be supported by the air guide plate 200 and moved in a direction away from the air guide plate 200; the reset member 320 connects the air outlet frame 100 and the limiting block 310 to accumulate elastic potential energy for reverse recovery of the limiting block 310 when the limiting block 310 moves in a direction away from the air guide plate 200.

[0052] It can be understood that the length direction of the air guide plate 200 can be the height direction. Of course, the length direction of the air guide plate 200 can also be the horizontal direction, or the length direction of the air guide plate 200 can also form an angle with the horizontal direction. The specific details are not limited here. In this embodiment, the length direction of the air guide plate 200 is the height direction.

[0053] Furthermore, the limit block 310 is provided on the side of the air guide plate 200, and the reset member 320 connects the air outlet frame 100 and the limit block 310. The reset member 320 is elastic. When the flow direction of the outlet air flow is inconsistent with the position of the air guide plate 200, the outlet air flow can drive the air guide plate 200 to rotate and abut against the limit block 310. The limit block 310 moves in the direction away from the air guide plate 200 as the air guide plate 200 rotates, so that the air guide plate 200 can rotate to be consistent with the flow direction of the outlet air flow. When the air guide plate 200 rotates to be consistent with the flow direction of the outlet air flow, the outlet air flow no longer drives the air guide plate 200 to rotate. At this time, the limit block 310 and the outlet air flow work together to limit the position of the air guide plate 200. At this time, the position of the air guide plate 200 can smoothly guide the outlet air flow. The air guide plate 200 has less obstruction to the outlet air flow, which is conducive to improving the smoothness of the air flow circulation, and realizes the function of the air guide plate 200 being able to adaptively adjust its rotation according to the flow direction of the outlet air flow.

[0054] Furthermore, the reset member 320 has elastic potential energy as the limit block 310 moves toward the reset member 320, so that the limit block 310 can abut against the air guide plate 200 and can be reset as the air guide plate 200 rotates, thereby allowing the limit member 300 to adaptively adjust as the flow direction of the outlet air flow changes. For example, when the flow direction of the outlet air flow is adjusted from the left side of the air outlet 110 to the right side of the air outlet 110, the position of the air guide plate 200 is adjusted from rotating toward the left side of the air outlet 110 to rotating toward the right side of the air outlet 110. At this time, the limit block 310 can adjust the position of abutment with the air guide plate 200 through the elasticity provided by the reset member 320, thereby making the rotation position of the air guide plate 200 consistent with the flow direction of the outlet air flow. The reset member 320 can be a spring or an elastic block, and the specifics are not limited here. It is only necessary that the reset member 320 has elasticity. The limiting member 300 of this solution has a simple structure and can easily realize the function of limiting the air guide plate 200, and ensure that the position of the air guide plate 200 is limited when the air guide plate 200 rotates to be consistent with the flow direction of the outlet air flow, thereby optimizing the structure of the air outlet component 10.

[0055] See also Figures 3 to 5 In one embodiment, the outer circumference of the stop block 310 is provided with a force-bearing surface 311 for the air deflector 200 to abut. The distance between the force-bearing surface 311 and the rotation axis of the air deflector 200 gradually increases from the end of the stop block 300 closest to the reset member 320 to the end farther from the reset member 320. This arrangement creates a clearance gap between the force-bearing surface 311 of the air deflector 200 and the air deflector 200. The clearance gap is smaller on the end closer to the reset member 320 and larger on the end farther from the reset member 320. When the flow direction of the outlet air flow is adjusted from the middle of the air outlet 110 to blow out toward the left side of the air outlet 110, the air guide plate 200 rotates toward the left side of the air outlet 110 driven by the outlet air flow. At this time, the air guide plate 200 can gradually squeeze the force-bearing surface 311 along the end close to the reset member 320 to the end away from the reset member 320. The avoidance gap formed by the force-bearing surface 311 and the air guide plate 200 has a larger space away from the end of the reset member 320, so as to reserve space for the position of the air guide plate 200 after rotation, so that the air guide plate 200 can be rotated to be consistent with the flow direction of the outlet air flow, thereby improving the smoothness of the rotation of the air guide plate 200.

[0056] In one embodiment, the force-bearing surface 311 is configured as a concave arc in a direction away from the rotation axis of the air deflector 200. It is understood that the concave arc configuration of the force-bearing surface 311 facilitates guiding the air deflector 200, allowing the air deflector 200 to rotate more smoothly when in contact with the stopper 300, thereby improving the efficiency of the air deflector 200's rotation.

[0057] See also Figure 3 and Figure 5 In one embodiment, the air outlet frame 100 is provided with a receiving groove 120 for accommodating the limiting member 300; wherein, the reset member 320 is provided in the receiving groove 120, and the force-bearing surface 311 of the limiting block 310 extends outward from the receiving groove 120 to be supported by the air guide plate 200.

[0058] It is understandable that by providing the receiving groove 120, the reset member 320 is provided in the receiving groove 120. At this time, the reset member 320 will not block the airflow, thereby facilitating the smoothness of the airflow. In addition, when the air guide plate 200 squeezes the force surface 311 of the limit block 310, the limit block 310 can move toward the receiving groove 120, so that the portion of the limit block 310 that is not in contact with the air guide plate 200 can also be provided in the receiving groove 120, thereby reducing the blocking area of ​​the airflow by the reset member 320 and improving the smoothness of the airflow. By providing the receiving groove 120, this solution optimizes the structure of the air outlet assembly 10, improves the space utilization rate at the air outlet 110, ensures the smoothness of the airflow, and at the same time, arranging the reset member 320 in the receiving groove 120 also makes the air outlet assembly 10 more beautiful.

[0059] See also Figure 6 and Figure 7 In one embodiment, the reset member 320 is a spring, and the sum of the minimum height of the spring when squeezed by the limit block 310 and the height of the limit block 310 is greater than the depth of the accommodating groove 120. Figure 6 and Figure 7 As shown, Figure 6 This is a structural diagram when the air guide plate does not squeeze the limit block; Figure 7 This is a structural diagram when the air guide plate rotates to squeeze the limit block and the spring is in the extreme compression position. The limit member located on the left side of the air guide plate is the first limit member 300a, and the limit member located on the right side of the air guide plate is the second limit member 300b. The sum of the minimum height of the left spring when squeezed by the limit block and the height of the limit block is H1, and the depth of the left accommodating groove is H2, H1>H2; the sum of the minimum height of the right spring when squeezed by the limit block and the height of the limit block is H3, and the depth of the left accommodating groove is H4, H3>H4. The minimum height of the spring when it is squeezed by the limit block 310 is the limit position of the air guide plate 200 rotating to squeeze the limit block 310. When the air guide plate 200 rotates to the limit position, the height of the spring and the height of the limit block 310 are greater than the depth of the accommodating groove 120, so that the limit block 310 can always limit the air guide plate 200, avoiding the air guide plate 200 rotating beyond the limit block 310 and causing the limit block 310 to lose its function of supporting the air guide plate 200, thereby improving the reliability of the limit member 300.

[0060] See also Figure 2 、 Figure 3 、 Figure 5 and Figure 7 In one embodiment, along the arrangement direction of the multiple air guide plates 200, the limiting members 300 located on both sides of the air guide plates 200 are the first limiting member 300a and the second limiting member 300b respectively; wherein, the minimum distance between the force-bearing surface 311 on the first limiting member 300a and the bottom of the accommodating groove 120 is greater than the minimum distance between the force-bearing surface 311 on the second limiting member 300b and the bottom of the accommodating groove 120.

[0061] It is understood that both sides of the air deflector 200 are provided with a stopper 300. The stopper 300 on one side of the air deflector 200 is a first stopper 300a, and the stopper 300 on the other side of the air deflector 200 is a second stopper 300b. The first stopper 300a and the second stopper 300b are spaced apart from each other. The magnitude of the outflow varies with different flow directions. For example, when the outflow direction is toward the left side of the air outlet 110, the outflow velocity is higher; when the outflow direction is toward the right side of the air outlet 110, the outflow velocity is lower.

[0062] On this basis, in order to make the first limiting member 300a and the second limiting member 300b better adapt to the different air flow rates, the first limiting member 300a and the second limiting member 300b of different sizes can be set, such as Figure 7As shown, in this embodiment, the volume of the first limiting member 300a is larger than that of the second limiting member 300b. Accordingly, when the air deflector 200 compresses the first limiting member 300a and the second limiting member 300b, the minimum distance between the force-bearing surface 311 of the first limiting member 300a and the bottom of the accommodating groove 120 is H5, and the minimum distance between the force-bearing surface 311 of the second limiting member 300b and the bottom of the accommodating groove 120 is H6, where H5>H6. When the air deflector 200 rotates to the extreme position toward the left side of the air outlet 110, it compresses the first limiting member 300a. At this time, the velocity of the outgoing airflow is relatively high, and the compressive force of the air deflector 200 on the first limiting member 300a is the greatest. By providing a larger first limiting member 300a, the first limiting member 300a is ensured to retain the air deflector 200. When the air guide plate 200 rotates to the extreme position toward the right side of the air outlet 110, it squeezes the second limiting member 300b. At this time, the flow rate of the outlet airflow is relatively low, and the squeezing force of the air guide plate 200 on the second limiting member 300b is relatively small. By providing a smaller second limiting member 300b, the second limiting member 300b can also support and limit the air guide plate 200. Thus, by providing the first limiting member 300a and the second limiting member 300b of different sizes, the air outlet assembly 10 can better adapt to airflow velocities of different sizes, thereby improving the applicability of the air outlet assembly 10. Of course, in other embodiments, the volume of the first limiting member 300a can also be the same as that of the second limiting member 300b, or the volume of the first limiting member 300a can be smaller than that of the second limiting member 300b. The specific setting can be based on the flow rate of the outlet airflow.

[0063] See also Figure 3 and Figure 5 In one embodiment, the air guide plate 200 is provided with an extrusion portion 210 for supporting the force-bearing surface 311 of the limiting member 300 , and the extrusion portion 210 is flush with the lower edge of the force-bearing surface 311 , or the extrusion portion 210 is higher than the lower edge of the force-bearing surface 311 .

[0064] It can be understood that the extrusion portion 210 is used to extrude the force-bearing surface 311 of the limiting member 300 so that the air guide plate 200 can be abutted against the limiting member 300, and the extrusion portion 210 is flush with the lower edge of the force-bearing surface 311, or the extrusion portion 210 is higher than the lower edge of the force-bearing surface 311, so that the air guide plate 200 can smoothly abut against the force-bearing surface 311 during the rotation process, thereby squeezing the force-bearing surface 311 during the rotation process, avoiding the situation where the extrusion portion 210 is lower than the lower edge of the force-bearing surface 311 and affecting the rotation of the air guide plate 200, thereby improving the reliability of the air outlet assembly 10.

[0065] In one embodiment, the limiting blocks 310 on both sides of each air deflector 200 abut against the air deflector 200. It is understandable that the limiting members 300 are provided on both sides of the air deflector 200, and the limiting blocks 310 of the limiting members 300 abut against the air deflector 200, so that the air deflector 200 can abut against the limiting blocks 310 during the rotation process. This configuration prevents the air deflector 200 from shaking during the rotation process, thereby improving the rotation stability of the air deflector 200.

[0066] See also Figure 1 and Figure 2 In one embodiment, the plurality of air guide plates 200 are arranged at intervals along the height direction within the air outlet 110. This arrangement allows the plurality of air guide plates 200 to evenly guide the outgoing airflow at the air outlet 110 to ensure smooth airflow. Furthermore, the plurality of air guide plates 200 arranged at intervals along the height direction can also direct the outgoing airflow to the left, middle, or right side of the air outlet 110 to meet different airflow direction requirements.

[0067] In one embodiment, the air outlet frame 100 is provided with the stoppers 300 at both ends of the air guide plate 200 in the longitudinal direction, so as to provide abutment against the two ends of the air guide plate 200. This arrangement allows the air guide plate 200 to abut against the stoppers 300 at both opposite ends along the longitudinal direction during rotation, thereby improving the stability of the stoppers 300 abutting against the air guide plate 200. This ensures that the rotation direction of the air guide plate 200 can be adaptively adjusted according to the flow direction of the outlet airflow, thereby ensuring that the air guide plate 200 can guide the outlet airflow blown out from the air outlet 110, thereby improving the reliability of the air outlet assembly 10.

[0068] The present invention also proposes an air treatment device 20, which includes the air outlet component 10 as described above. The specific structure of the air outlet component 10 refers to the above embodiment. Since the air treatment device 20 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0069] See also Figure 1 In one embodiment, the air treatment device 20 further includes a housing 21 , and the air outlet assembly 10 is disposed at an upper end of the housing 21 .

[0070] It can be understood that the air treatment device 20 also includes a fan, which has multiple working gears. The flow direction of the air flow blown out by the fan at different working gears is different. The fan of this scheme has three working gears, gear one, gear two and gear three. When the fan is in the working gear one, the fan tends to blow air toward the left side of the air outlet 110; when the fan is in the working gear two, the fan tends to blow air toward the middle of the air outlet 110; when the fan is in the working gear three, the fan tends to blow air toward the right side of the air outlet 110, that is, the three working gears of the fan, the corresponding air outlet directions are respectively towards the left side, the middle and the right side of the air outlet 110, and the three working gears correspond to three air outlet directions.

[0071] Furthermore, the air outlet frame 100 of the air outlet assembly 10 can be detachably connected to the housing 21. The detachable connection method includes, but is not limited to, a threaded connection or a snap connection. The air outlet assembly 10 is disposed at the upper end of the housing 21, so that the air flow can be blown outward from the upper end of the air treatment device 20, so that the air flow can flow from a high point to a low point, which is conducive to the air flow outside the air treatment device 20.

[0072] See also Figure 8 and Figure 9 , Figure 8 The simulation results of the air flow in the traditional air handling device are shown in Figure 2. Figure 9 This is a simulation result diagram of the air flow in the air treatment device 20 of the present application, wherein the fans are all in the third gear, that is, the fans tend to blow air to the right side of the air outlet 110, and the fan speed is 3000 rpm.

[0073] Because the traditional air handling device includes an air outlet grille, the angle of the air outlet grille cannot be adjusted, so the air outlet grille blocks the flow of air. Figure 8 It can be seen that Figure 8 The windshield area 22 where the middle air outlet grille blocks the airflow is relatively large.

[0074] Because the air treatment device 20 of this solution includes an air guide plate 200 and a stopper 300, when the fan tends to blow air to the right side of the air outlet 110, the air guide plate 200 can be rotated to be consistent with the flow direction of the air flow, reducing the obstruction of the air guide plate 200 to the air flow, which is conducive to improving the smoothness of the air flow. Figure 9 It can be seen that Figure 9 The wind shielding area 22 where the middle wind deflector 200 blocks the airflow is relatively small.

[0075] right Figure 8 The air volume at the air outlet 110 is tested and the detected air volume is 6.3m3 / h;

[0076] right Figure 9The air volume at the air outlet 110 is tested and the detected air volume is 6.7m3 / h;

[0077] The air volume data detected above indicates that the air outlet assembly 10 of this embodiment improves the air volume at the air outlet 110 of the air handling device. Compared to conventional air handling devices, the air outlet 110 of this embodiment improves the air volume by 6%. This indicates that the air outlet assembly 10 of this embodiment can improve the smoothness of airflow at the air outlet 110 of the air handling device.

[0078] The above descriptions are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present description and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
