Description

Technical Field

[0001] The present application relates to the technical field of air handling equipment, and in particular to an air guide assembly and air handling equipment. Background Art

[0002] Air handling equipment, such as air conditioning equipment, generally includes an air outlet and an air guide plate disposed at the air outlet. The air guide plate is rotatably connected to the air outlet, and the air supply direction of the air outlet is changed by changing the opening angle of the air guide plate relative to the air outlet.

[0003] However, the above-mentioned method of adjusting the air supply direction results in a relatively limited air supply area of ​​the air handling equipment. Summary of the invention

[0004] One aspect of the present application provides an air guide assembly, which is installed at the air outlet of an air handling device, and the air guide assembly includes: N adjustment assemblies, each of which is movably connected in sequence along the length direction of the air outlet; wherein the adjustment assembly includes a bearing plate and a plurality of air guide blades, the bearing plate is movably arranged at the air outlet, each of the air guide blades is connected to the bearing plate and is arranged in sequence along the plate surface of the bearing plate; at least one first drive assembly, the first drive assembly is connected to the adjustment assembly, and drives the bearing plate of the corresponding adjustment assembly to move, so that the bearing plates of all the adjustment assemblies are linked; wherein N is a positive integer greater than or equal to 4, the N adjustment assemblies include 2 end adjustment assemblies and N-2 middle adjustment assemblies, the end adjustment assemblies are adjustment assemblies located at both ends of the length direction of the air outlet, and one end of the end adjustment assembly facing away from the middle adjustment assembly is rotatably connected to the air outlet.

[0005] The present application provides an air guide assembly and an air treatment device, wherein the air guide assembly is installed at the air outlet of the air treatment device, and the air guide assembly includes N adjustment assemblies and at least one first drive assembly. The N adjustment assemblies are movably connected in sequence along the length direction of the air outlet, and the first drive assembly can drive the adjustment assembly to move. The adjustment assembly includes a bearing plate and a plurality of air guide blades, the bearing plate is movably arranged at the air outlet, and each air guide blade is connected to the bearing plate and arranged in sequence along the plate surface of the bearing plate.

[0006] In this way, by sequentially arranging N adjusting components in the length direction of the air outlet, the airflow at the air outlet can flow outward under the guidance of the N adjusting components. Since the bearing plates in the N adjusting components are movably arranged at the air outlet, the bearing plates in the N adjusting components can move relative to the air outlet and extend out of the air outlet under the drive of the first driving component, so that the air supply angle can be adjusted by the bearing plates extending out of the air outlet and the multiple air guide blades arranged on the bearing plates, thereby expanding the air supply range of the air guide components, reducing the air supply blind area, increasing the coverage range of the air handling equipment, and making the air supply efficiency of the air handling equipment higher, achieving efficient temperature control, and better comfort.

[0007] In addition, N is a positive integer greater than or equal to 4. The N adjusting components include 2 end adjusting components and N - 2 intermediate adjusting components. The 2 end adjusting components are located at both ends in the length direction of the air outlet, and can adjust the air supply angles on both sides of the air outlet, expand the air supply coverage area of the air handling device, and achieve large-area air supply. The N - 2 intermediate adjusting components are located between the two end adjusting components, and can guide and adjust the air in the central area of the air outlet, avoiding the too strong local air flow velocity or uneven temperature distribution caused by the direct blowing of the intermediate air flow. Through the cooperation of the 2 end adjusting components and the N - 2 intermediate adjusting components, the air supply angle of the air handling device can be flexibly adjusted. While expanding the air supply coverage area of the air handling device, the air supply blind area at the edge area of the air handling device and the strong wind aggregation phenomenon in the central area can be effectively eliminated, the air supply uniformity of the air guiding component can be improved, the indoor temperature uniformity can be improved, and the indoor comfort can be enhanced.

[0008] In a possible implementation manner, the number of the first driving components is two, and the two first driving components are respectively connected to the two end adjusting components, and the first driving component drives the carrier plate of the end adjusting component to rotate.

[0009] In this way, the two first driving components can respectively drive the 2 end adjusting movements, so that the carrier plates of the 2 end adjusting components and the N - 2 intermediate adjusting components are linked.

[0010] In a possible implementation manner, the first driving component is connected to one end of the end adjusting component close to the air outlet.

[0011] In this way, the parts of the end adjusting component and the intermediate adjusting component that can extend out of the air outlet are more, and almost the whole can be exposed. The interference and limitation of the air duct on the end adjusting component and the intermediate adjusting component can be avoided, the air supply blind area can be avoided, and the air supply area of the adjusting component can be further expanded.

[0012] In a possible implementation manner, the first driving component also drives each air guiding blade in the end adjusting component to rotate relative to the carrier plate. The first driving component includes: a driving motor; a transmission member, and the transmission member is drivingly connected between the driving motor and the adjusting component; wherein, the transmission member drives the carrier plate to rotate, and one of the driving motor and the transmission member drives each air guiding blade to rotate.

[0013] In this way, the first driving component can drive each air guiding vane in the end regulating component to rotate relative to the bearing plate, and adjust the air supply angle by changing the deflection angle of the air guiding vane, which can better expand the air supply area of the first regulating component and further expand the air supply coverage area of the air handling device. Moreover, the first driving component only cooperates with a driving motor and a transmission component, which not only drives each air guiding vane on the bearing plate of the end regulating component to rotate, but also drives the bearing plate of the end regulating component to rotate, simplifying the driving mode of the end regulating component.

[0014] In a possible implementation manner, the transmission component includes: a first gear pair, which is in transmission connection with the driving motor; a second gear pair, which is in transmission connection between the first gear pair and the bearing plate, and the second gear pair drives the bearing plate to rotate; wherein, the driving motor or the first gear pair drives each air guiding vane to rotate.

[0015] In this way, during the continuous operation of the driving motor, the driving motor or the first gear pair drives each air guiding vane to rotate continuously. Moreover, by transmitting the power of the driving motor to the second gear pair through the first gear pair and designing the transmission of the first gear pair and the second gear pair, it can be realized that the first gear pair transmits power to the second gear pair or the first gear pair does not transmit power to the second gear pair. Furthermore, the second gear pair can drive the bearing plate to move or keep the bearing plate stationary.

[0016] In a possible implementation manner, the air guiding component further includes N - 2 second driving components, and each second driving component is respectively connected to each intermediate regulating component; wherein, the second driving component drives each air guiding vane in the corresponding intermediate regulating component to rotate relative to the bearing plate.

[0017] In this way, the angles of the air guiding vanes of each intermediate regulating component can be flexibly adjusted through the second driving component, which can not only allow the air in the intermediate regulating component area to pass through smoothly, but also control the air supply direction in the intermediate regulating component area by changing the deflection angles of the air guiding vanes. With such a setting, the adjustment ability of the air flow in the central area of the air outlet is greatly improved, enabling the air handling device to better adapt to different usage scenarios and requirements, and enhancing the uniformity and comfort of the air supply of the air handling device.

[0018] In a possible implementation manner, when N is an odd number, the intermediate regulating component includes a central regulating component located at the central position of the air outlet; the air guiding component further includes N - 3 second driving components, and each second driving component is respectively connected to other intermediate regulating components except the central regulating component, and each air guiding vane in the central regulating component is fixed to the bearing plate, and the leaf surface direction of the air guiding vane is the length direction of the bearing plate; wherein, the second driving component drives each air guiding vane in the corresponding intermediate regulating component to rotate relative to the bearing plate.

[0019] In this way, the air guide vanes of the central adjustment component can form a directional air guiding structure for the air flow in the central area of the air outlet. The air guide vanes of each of the other intermediate adjustment components except the central adjustment component can rotate relative to the carrier plate under the drive of the second drive component, and the air supply angle can be adjusted by changing the deflection angle of the air guide vane. This makes the adjustment of the air supply area by the intermediate adjustment component more flexible, thereby expanding the air supply coverage area of the air handling equipment.

[0020] In a possible implementation manner, N is an odd number greater than or equal to 5, and N - 2 intermediate adjustment components include a central adjustment component located at the central position of the air outlet; the number of the first drive components is one, and the first drive component is connected to the central adjustment component; wherein, the first drive component includes a first drive part, and the first drive part drives the carrier plate of the central adjustment component to translate in and out relative to the air outlet.

[0021] In this way, the carrier plate of the central adjustment component can be driven by the first drive part to translate in and out relative to the air outlet, and the flexible adjustment of the air outlet condition in the central area of the air outlet can be realized. When the carrier plate of the central adjustment component translates inwards, the air outlet area in the central area can be reduced, making the air more concentrated and enhancing the air supply intensity. When the carrier plate of the central adjustment component translates outwards, the air outlet can be enlarged to disperse the air flow. At the same time, the carrier plate of the central adjustment component drives the carrier plates of other adjustment components to rotate, and the air supply angles of the carrier plates of each adjustment component can be adjusted, so that the air supply coverage area of the air handling equipment can be flexibly adjusted, the air supply uniformity and flexibility of the air handling equipment can be improved, and the air conditioning requirements of different scenarios can be met.

[0022] In a possible implementation manner, the first drive part includes: a stepping motor, which is installed on the carrier plate of the central adjustment component; a transmission chain, which is arranged at the air outlet, and the transmission chain is in transmission connection with the stepping motor and expands and contracts along the direction perpendicular to the air outlet.

[0023] In this way, through the cooperation of the transmission chain and the stepping motor, efficient and reliable power transmission can be realized to ensure the stability and efficiency of the telescopic movement of the carrier plate of the central adjustment component along the direction perpendicular to the air outlet. And, since the transmission chain has high strength and rigidity, the above structure can provide sufficient power and load-bearing capacity for the in-and-out translation of the carrier plate of the central adjustment component.

[0024] In a possible implementation manner, in the central adjustment component, each air guide vane is fixed to the carrier plate, and the leaf surface direction of the air guide vane is the length direction of the carrier plate.

[0025] In this way, the air guide vanes of the central adjustment assembly can form a directional air guiding structure for the air flow in the central area of the air outlet. Through the blocking and guiding effects of the air guide vanes, only a small part of the air flow is allowed to flow out from the gaps between the adjacent air guide vanes of the second adjustment assembly. Most of the air flow in the central area can be guided along the length direction of the air outlet to both ends of the air outlet, and flow outwards through the air guiding channels formed by the air guide vanes on the end adjustment assembly and other intermediate adjustment assemblies. It can effectively avoid the problems of too strong local air flow velocity or uneven temperature distribution in the central area of the air outlet, significantly improve the air supply uniformity in the central area of the air outlet, and achieve efficient diffused air supply of the air handling equipment.

[0026] In a possible implementation manner, in the central adjustment assembly, each air guide vane is rotatably connected to the carrier plate; the first driving assembly further includes a second driving part, and the second driving part drives each air guide vane in the central adjustment assembly to rotate relative to the carrier plate.

[0027] In this way, the angles of the air guide vanes in the central adjustment assembly can be flexibly adjusted by the second driving part, which can not only allow the air in the central area to pass through smoothly, but also control the air supply direction in the central area of the air outlet by changing the deflection angles of the air guide vanes. With such a setting, the adjustment ability of the air flow in the central area of the air outlet is greatly improved, enabling the air handling equipment to better adapt to different usage scenarios and requirements, and enhancing the air supply uniformity and comfort of the air handling equipment.

[0028] In a possible implementation manner, the air guide assembly further includes N - 1 second driving assemblies, and each second driving assembly is respectively connected to other adjustment assemblies except the central adjustment assembly; wherein, the second driving assembly drives each air guide vane in the corresponding adjustment assembly to rotate relative to the carrier plate.

[0029] In this way, the air guide vanes of other adjustment assemblies except the central adjustment assembly can be driven to rotate relative to the carrier plate by the second driving assembly, and the air supply direction in the central area of the air outlet can be controlled by changing the deflection angles of the air guide vanes. With such a setting, the adjustment ability of the air flow at the air outlet is greatly improved, enabling the air handling equipment to better adapt to different usage scenarios and requirements, and enhancing the air supply uniformity and comfort of the air handling equipment.

[0030] In a possible implementation manner, at least part of the inner ends of the carrier plates of adjacent adjustment assemblies are rotatably and slidably connected, and the inner end of the carrier plate is the end of the carrier plate facing the inside of the air outlet; the outer ends of the carrier plates of all adjacent adjustment assemblies are rotatably and slidably connected, and the outer end of the carrier plate is the end of the carrier plate facing the outside of the air outlet.

[0031] In this way, during the process of the bearing plate of each adjustment component moving outward relative to the air outlet, it can slide along the length direction of the air outlet while rotating, thereby avoiding the bearing plate of each adjustment component from being stuck due to movement interference and unable to operate normally. Ensure that the bearing plates of each adjustment component can cooperate smoothly and move along the expected trajectory. Thus, each adjustment component can flexibly and stably achieve movement relative to the air outlet, effectively improving the coordination and reliability of the operation of the air handling equipment.

[0032] On the other hand, the present application provides an air handling equipment, including: an equipment body, the equipment body includes a housing and an evaporator and a fan located inside the housing; and the air guiding component as described above, the air guiding component is installed at the air outlet surrounded by the housing.

[0033] For the air handling equipment provided by the present application, since it includes the aforementioned air guiding component, it has all the technical effects of the air guiding component, which will not be elaborated here.

[0034] In a possible implementation manner, the evaporator is located within the coverage area of the second adjustment component of the air guiding component.

[0035] In this way, the evaporator can be correspondingly arranged in the middle area in the length direction of the housing, so that air can flow more evenly on both sides of it, forming a relatively symmetric flow field. This can avoid large disturbances or uneven flow phenomena in air flow, allowing air to pass through the evaporator for heat exchange more smoothly, and then blowing out smoothly from the air outlet, which can further improve the uniformity and stability of air supply, reduce the uneven distribution of indoor air flow and the generation of local eddies, and create a more comfortable indoor air environment for users.

[0057] As described in the background technology, conventional air conditioners are equipped with swingable air guide plates in the air duct to adjust the air supply angle. For example, the horizontally arranged air guide plates swing up and down to achieve up and down air sweeping, and the vertically arranged air guide plates move left and right to achieve left and right air sweeping. Among them, the swing angles of all air guide plates are uniformly controlled by connecting rods, thereby adjusting the overall air supply area of ​​the air conditioner.

[0058] However, in the above-mentioned method of adjusting the air supply area, the size of the air supply area is positively correlated with the size of the air outlet area. This will result in a relatively limited air supply area for the air conditioner, a small air supply coverage area, and inability to achieve air supply over a large area. In addition, since the air guide plate is located in the air duct and can only be deflected at the same rotation angle, there will be an air supply blind area when adjusting the air supply angle, resulting in a significant indoor temperature difference and the comfort needs to be improved.

[0059] In view of this, an embodiment of the present application provides an air guide assembly and an air treatment device, wherein the air guide assembly is installed at the air outlet of the air treatment device, and the air guide assembly includes N adjustment assemblies and at least one first drive assembly. The N adjustment assemblies are movably connected in sequence along the length direction of the air outlet, and the first drive assembly can drive the adjustment assembly to move. Among them, the adjustment assembly includes a bearing plate and a plurality of air guide blades, the bearing plate is movably arranged at the air outlet, and each air guide blade is connected to the bearing plate and arranged in sequence along the plate surface of the bearing plate.

[0060] In this way, by sequentially arranging N adjusting components in the length direction of the air outlet, the airflow at the air outlet can flow outward under the guidance of the N adjusting components. Since the bearing plates in the N adjusting components are movably arranged at the air outlet, the bearing plates in the N adjusting components can move relative to the air outlet and extend out of the air outlet under the drive of the first driving component, so that the air supply angle can be adjusted by the bearing plates extending out of the air outlet and the multiple air guide blades arranged on the bearing plates, thereby expanding the air supply range of the air guide components, reducing the air supply blind area, increasing the coverage range of the air handling equipment, and making the air supply efficiency of the air handling equipment higher, achieving efficient temperature control, and better comfort.

[0061] Wherein, N is a positive integer greater than or equal to 4, and the N adjustment components include 2 end adjustment components and N-2 intermediate adjustment components, the end adjustment components are located at both ends of the length direction of the air outlet, the intermediate adjustment component is located between the two end adjustment components, and the end of the end adjustment component away from the intermediate adjustment component is rotated and connected to the air outlet. In this way, the two end adjustment components are respectively close to the two ends of the length direction of the air outlet, and the air supply angles on both sides of the air outlet can be adjusted to expand the air supply coverage area of ​​the air treatment equipment and realize air supply in a large area. The N-2 intermediate adjustment components are located between the two end adjustment components, and the wind in the central area of ​​the air outlet can be guided and adjusted to avoid excessive local air flow velocity or uneven temperature distribution caused by direct blowing of the intermediate airflow. Through the cooperation of the two end adjustment components and the N-2 intermediate adjustment components, the air supply angle of the air treatment equipment can be flexibly adjusted, and while expanding the air supply coverage area of ​​the air treatment equipment, the air supply blind area in the edge area of ​​the air treatment equipment and the strong wind gathering phenomenon in the central area can be effectively eliminated, the uniformity of the air supply of the air guide component is improved, the temperature uniformity in the room is improved, and the comfort in the room is improved.

[0062] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0063] The embodiment of the present application provides an air treatment device, which includes but is not limited to air conditioning equipment, humidifiers, dehumidifiers, ventilation equipment, heat recovery ventilation systems, air purifiers, and fresh air equipment. In the embodiment of the present application, the air treatment equipment is an air conditioning equipment as an example for description. Among them, the air conditioning equipment may include a wall-mounted air conditioner, a vertical air conditioner, a central air conditioner, a duct air conditioner, etc.

[0064] The following description will be specifically made by taking the air handling device 1 as a wall-mounted air conditioner as an example.

[0065] Figure 1 A schematic diagram of the structure of an air treatment device provided in an embodiment of the present application. Figure 2 This is a top view of an air treatment device provided in an embodiment of the present application. Figure 1 and Figure 2As shown, the air handling device 1 includes a device body 10. The device body 10 includes a housing 11. The housing 11 defines an air outlet 12. The air handling device 1 can send air out through the air outlet 12. Taking a wall-mounted air conditioner as an example, the air handling device 1 is installed on an indoor wall. The air outlet 12 can be arranged on the front surface of the device body 10 (the surface facing away from the wall) and near the lower part. For example, the air outlet 12 can be arranged to incline downward, so that the air supply area of the air handling device 1 is more appropriate.

[0066] A wind guiding component 20 is arranged at the air outlet 12 of the device body 10. The wind guiding component 20 is used to adjust the air supply direction and air supply area of the air handling device 1, so as to realize flexible air supply of the air handling device 1.

[0067] Figure 3 It is a schematic structural diagram of a wind guiding component provided by an embodiment of the present application. Refer to Figures 1 to 3 As shown, the wind guiding component 20 includes N adjusting components 100, where N is a positive integer greater than or equal to 4. The N adjusting components 100 are all arranged in the air duct of the device body 10. There is an installation base for the N adjusting components 100 in the air duct, and the N adjusting components 100 can be installed on this installation base.

[0068] For the convenience of description, in this embodiment, a basic air duct wall 13 is defined (see Figure 1 and Figure 3 shown). The basic air duct wall 13 is, for example, the side wall surface of the air duct close to the wall. The N adjusting components 100 can be installed on the basic air duct wall 13. The N adjusting components 100 can be directly installed on the basic air duct wall 13, or can be installed on the basic air duct wall 13 through other supporting components. Moreover, the N adjusting components 100 can be located at the air outlet 12 of the device body 10 and are sequentially movably connected along the length direction of the air outlet 12. For example, the N adjusting components 100 can cover most of the area of the air outlet 12, so as to adjust the air supply direction and air supply area of the device body 10 through the adjusting components 100.

[0069] Refer to Figure 2 and Figure 3 shown. The N adjusting components 100 include 2 end adjusting components 100a and N - 2 intermediate adjusting components 100b. Among them, the end adjusting components 100a are located at both ends of the length direction of the air outlet, and can adjust the air supply angles on both sides of the air outlet 12. By flexibly changing the air flow directions on both sides of the air outlet 12, the air flow can be guided to a wider space area, expanding the air supply coverage area of the air handling device 1 and realizing large-area air supply.

[0070] It can be understood that when the two end adjustment components 100a expand outward relative to the air outlet 12 to supply air to both sides, a certain blank area will be generated in the middle part of the air outlet 12. A part of the air flowing out of the air outlet 12 can directly flow out from the blank area in the middle without being guided, which may affect the uniformity of air supply of the air guide component 20.

[0071] Therefore, the middle adjustment component 100b is located between the two end adjustment components 100a, and the middle adjustment component 100b can guide and adjust the wind in the central area of ​​the air outlet 12, effectively avoiding problems such as excessive local wind speed and uneven temperature caused by direct blowing of the middle airflow, thereby making the airflow output in the central area of ​​the air outlet 12 more balanced and smooth, thereby improving the indoor comfort.

[0072] In this way, through the coordinated cooperation of the end adjustment component 100a and the middle adjustment component 100b, the air supply angle of the air treatment equipment 1 can be flexibly adjusted. While expanding the air supply coverage area of ​​the air treatment equipment 1, the air supply blind spots in the edge areas of the air treatment equipment 1 and the strong wind gathering phenomenon in the central area can be effectively eliminated, so that the air supply uniformity of the air treatment equipment is better, the indoor temperature uniformity is improved, and the indoor comfort is enhanced.

[0073] As an implementation method, N adjustment components 100 can be symmetrically arranged. Specifically, the N adjustment components 100 are symmetrically arranged with the center line between them as the axis of symmetry. In this way, for the air guide component 20 as a whole, the structural symmetry is better, the overall force is more balanced, the stability is better, and the reliability is higher. In addition, the symmetrical arrangement can keep the coverage of the air supply area of ​​the N adjustment components 100 symmetrical, the air supply coverage area on both sides of the air outlet is the same and there is no obvious difference, the air guide component 20 has better universality, and the application scenarios of the air treatment equipment 1 are richer.

[0074] In addition, in order to achieve smooth rotation of N adjustment components 100 relative to the air outlet 12, the end of the supporting plate 110 of the two end adjustment components 100a that is away from the middle adjustment component 100b needs to be rotated and connected to the air outlet 12 to form a stable rotation fulcrum to ensure the stability of the supporting plate 110 of the two end adjustment components 100a during the rotation process and avoid shaking during the rotation process.

[0075] Continue to refer to Figure 3As shown in the figure, the adjustment assembly 100 may include a carrier plate 110 and a plurality of air guide vanes 120. The carrier plate 110 is movably arranged at the air outlet 12. Each carrier plate 110 can be close to the base air duct wall 13, so as to facilitate the installation of the adjustment assembly 100 on the base air duct wall 13 through the carrier plate 110. Each air guide vane 120 is connected to the carrier plate 110 and is sequentially arranged along the plate surface of the carrier plate 110. When the carrier plate 110 moves relative to the air outlet 12, the air guide vanes 120 on the carrier plate 110 move accordingly, and each air guide vane 120 can flexibly adjust the flow direction and flow angle of the flowing air.

[0076] Continue to refer to Figure 3 As shown in the figure, the air guide assembly 20 further includes at least one first driving assembly 200. The first driving assembly 200 can be connected to the adjustment assembly 100 and drive the corresponding carrier plate 110 to move. In this way, by driving the N adjustment assemblies 100 to move through the first driving assembly 200, the angle adjustment or position movement of the carrier plate 110 can be realized. Thus, the adjustment of the air supply direction and air supply area by the adjustment assembly 100 can be realized to adapt to different air supply requirements. In this way, the N adjustment assemblies 100 can supply air to different areas respectively, which can expand the air supply area of the air guide assembly 20 and expand the air supply coverage area of the air handling device 1.

[0077] Taking the air handling device 1 as a wall-mounted air conditioner as an example, the air conditioner has a larger air supply coverage area, can adjust the temperature of the entire indoor space more evenly, reduce the indoor temperature difference, and improve the overall comfort of the indoor environment. Moreover, with a larger air supply coverage area, the air conditioner can also reach the set temperature target faster. The air conditioner can complete the refrigeration target or heating target in a shorter time, and the energy efficiency of the air conditioner is higher. In addition, with a larger air supply coverage area, the air flow distribution area blown by the air conditioner is wider and the air flow velocity is more gentle, which can reduce the discomfort caused by strong wind in local areas and provide a more gentle air supply effect, making users feel more natural and comfortable in the air-conditioned environment.

[0078] It should be noted that since the N adjustment assemblies are all movably connected, therefore. The first driving assembly 200 only needs to drive the carrier plate 110 of any one of the N adjustment assemblies 100 to move, and the power can be transmitted to the carrier plates 110 of all the adjustment assemblies 100 through the linkage structure between the adjustment assemblies 100, so as to realize the synchronous linkage of the N adjustment assemblies.

[0079] In this way, the number of the first driving assemblies 200 is reduced to the greatest extent, the structure of the first driving assembly 200 is simpler, the overall space occupied by the first driving assembly 200 is smaller and the weight is lighter. It can save the layout space of the air handling device 1, facilitate the setting of other components, and effectively reduce the manufacturing cost and operation energy consumption of the air handling device 1.

[0080] In some embodiments, the air guiding assembly 20 may include two first driving assemblies 200. The two first driving assemblies 200 are respectively connected to two end adjusting assemblies 100a, and the two first driving assemblies respectively drive the carrier plates of the two end adjusting assemblies 100a to rotate.

[0081] On this basis, the two first driving assemblies 200 may be respectively connected to one end of the two end adjusting assemblies 100a away from the central adjusting assembly 100c. That is to say, the positions of the first driving assemblies 200 are closer to the ends in the length direction of the air outlet 12.

[0082] In this way, since the rotation centers of the two end adjusting assemblies 100a are respectively located at the positions where the two first driving assemblies 200 are located, by making the first driving assemblies 200 closer to the ends in the length direction of the air outlet 12, the rotating arms between the rotation centers of the two end adjusting assemblies 100a and the other ends of the two end adjusting assemblies 100a are longer.

[0083] When the first driving assemblies 200 have the same driving efficiency, compared with the first driving assemblies 200 being close to the opposite ends of the two end adjusting assemblies 100a and the intermediate adjusting assembly 100b, when the first driving assemblies 200 are close to the ends of the two end adjusting assemblies 100a that are away from the intermediate adjusting assembly 100b, the two end adjusting assemblies 100a and the intermediate adjusting assembly 100b can extend further out of the air outlet 12.

[0084] In this way, when the two end adjusting assemblies 100a and the intermediate adjusting assembly 100b move outward relative to the air outlet 12, the two end adjusting assemblies 100a and the intermediate adjusting assembly 100b can extend further out of the air outlet 12, and more parts are exposed outside the air outlet 12.

[0085] In this way, the air supply areas of the two end adjusting assemblies 100a and the intermediate adjusting assembly 100b are larger, and the overall air supply coverage area of the air guiding assembly 20 is wider. At the same time, the parts of the two end adjusting assemblies 100a and the intermediate adjusting assembly 100b located inside the air duct are fewer, and the air duct blocks the adjusting assemblies less, which can avoid the occurrence of air supply blind spots. And since the parts of the two end adjusting assemblies 100a and the intermediate adjusting assembly 100b located inside the air duct are very few, the movement space required by the two end adjusting assemblies 100a and the intermediate adjusting assembly 100b inside the air duct is also smaller, which can avoid interference between the two end adjusting assemblies 100a and the intermediate adjusting assembly 100b and the air duct wall, and is beneficial to reducing the overall volume of the air handling device 1.

[0086] In addition, the first driving assembly 200 can also drive each air guiding vane 120 in the end adjusting assembly 100a to rotate relative to the bearing plate 110, causing the positions of the air guiding vanes 120 in the end adjusting assembly 100a to change relative to the bearing plate 110. In this way, when the first driving assembly 200 drives the bearing plate 110 of the end adjusting assembly 100a to move, the air guiding vanes 120 on the bearing plate 110 of the end adjusting assembly 100a move together with the bearing plate 110, and at the same time, the air guiding vanes 120 can also move relative to the bearing plate 110.

[0087] Figure 4 This is a schematic three-dimensional structure diagram of an adjusting assembly provided by an embodiment of the present application. Refer to Figure 4 As shown, as an implementation manner, each air guiding vane 120 of the end adjusting assembly 100a can be rotatably connected to the bearing plate 110. When the air guiding vane 120 is rotatably connected to the bearing plate 110, the air guiding vane 120 can further include a vane body 121 and a rotating shaft 122. The rotating shaft 122 is connected to the vane body 121, and the rotating shaft 122 can be integrally formed on the vane body 121 to form an integrally formed air guiding vane 120. The rotating shaft 122 can be connected to one end of the vane body 121 facing the bearing plate 110, the rotating shaft can be perpendicular to the plate surface of the bearing plate 110, and the vane surfaces of the air guiding vanes 120 can also be perpendicular to the plate surface of the bearing plate 110. The first driving assembly 200 can drive each air guiding vane 120 to rotate along its own rotating shaft to realize the overall unified swing of all the air guiding vanes 120 to the left and right ends of the air outlet 12.

[0088] In addition, the rotating shaft 122 can be located on the central axis of the vane body 121. In this way, the air guiding vane 120 has good force balance, better stability and higher reliability during the rotation process. Moreover, the widths of the vane body 121 on both sides of the central axis are kept the same, which is more conducive to the layout and installation of the air guiding vanes 120. The distance between adjacent vanes can be designed according to the width of the vane body 121, so that the air guiding vanes 120 are evenly spaced. In addition, the air guiding vane 120 can also be better applied to the scenario of 360° rotation. The movement range of the air guiding vane 120 is the smallest, and the required movement space of the air guiding vane 120 is also the smallest, which can reduce the occupied space of the air guiding assembly 20 and is beneficial to the miniaturization of the air treatment device 1.

[0089] Exemplarily, the rotating shaft 122 may include a disc structure (not shown in the figure). An installation groove (not shown in the figure) may be provided on the bearing plate 110. The disc structure may rotate within the installation groove to enable the air guiding vanes 120 to rotate on the bearing plate 110. Among them, the disc structure may be completely accommodated within the installation groove. For example, the disc structure is flush with the front surface of the bearing plate 110 (the surface of the bearing plate 110 facing the vane body 121). In this way, the disc structure does not protrude on the surface of the bearing plate 110, which helps to reduce the wind resistance of the adjusting assembly 100. Moreover, the flatness of the adjusting assembly 100 is better and more aesthetically pleasing.

[0090] In this way, the first driving assembly 200 can drive the movement of each air guiding vane 120 on the bearing plate 110 of the end adjusting assembly 100a, causing the position of each air guiding vane 120 of the end adjusting assembly 100a to change relative to the bearing plate 110 of the end adjusting assembly 100a. The angle between each air guiding vane 120 and a certain direction of the plate surface of the bearing plate 110 changes, and each air guiding vane 120 deflects uniformly towards one side of the air outlet 12 to adjust the air supply angle of the air guiding assembly 20.

[0091] With such a setting, by driving the movement of the bearing plate 110 of the end adjusting assembly 100a through the first driving assembly 200, the position of the bearing plate 110 of the end adjusting assembly 100a changes relative to the air outlet 12, and the distance between the bearing plate 110 and the base air duct wall 13 changes. The bearing plate 110 moves together with each air guiding vane 120 on the bearing plate 110, which can change the position of the air guiding vane 120 relative to the air outlet 12, weakening or even eliminating the limitation of the deflection angle of the air guiding vane 120 by the air duct. Thus, the deflection angle range of the air guiding vane 120 relative to the bearing plate 110 can be increased. When the deflection angle of the bearing plate 110 relative to the air outlet 12 is adjustable, on the basis of changing the deflection angle of the bearing plate 110, adjusting the deflection angle of the air guiding vane 120 relative to the bearing plate 110 can further increase the deflection angle range of the air guiding vane 120 relative to the air outlet 12.

[0092] In this way, the first driving component 200 not only drives the movement of each air guiding vane 120 on the bearing plate 110, but also drives the bearing plate 110 together with the air guiding vanes 120 to move, making the driving mode of the first driving component 200 for the adjusting component 100 more flexible. The air supply angle of the air guiding component 20 can be flexibly adjusted, the air supply area of the air guiding component 20 can be expanded, and the adjustment accuracy of the air guiding component 20 for the air supply area can be improved. Thus, by adjusting the air supply angle of the air guiding component 20 through the first driving component 200, the air supply area of the air guiding component 20 can be made to avoid the user's activity area, preventing physical discomfort or health problems caused by the cold air blowing directly on the user. It is also possible to drive the air supply angle of the air guiding component 20 to continuously change through the first driving component 200, avoiding the air guiding component 20 blowing directly on a certain area for a long time and improving the uniformity of the overall indoor temperature.

[0093] Figure 5 This is a schematic diagram of the driving mode of the first driving component driving the end adjusting component 100a provided by the embodiment of the present application. Refer to Figure 5 As shown, in this embodiment, the first driving component 200 used to drive the movement of the end adjusting component 100a includes a driving motor 210 and a transmission member 220. The transmission member 220 is connected between the first driving motor 210 and the end adjusting component 100a. The driving motor 210 is used to provide driving force, and the driving motor 210 can be electrically connected to a control member to control the operation of the driving motor 210 through the control member. The transmission member 220 is used to transmit the power of the driving motor 210 to the end adjusting component 100a to drive the movement of the end adjusting component 100a.

[0094] Among them, the bearing plate 110 of the end adjusting component 100a can be in transmission connection with the transmission member 220. The first driving component 200 transmits the driving force to the transmission member 220, and drives the bearing plate 110 to move through the transmission member 220. Each air guiding vane 120 on the bearing plate 110 can be directly connected to the output end of the driving motor 210, and each air guiding vane 120 is directly driven to rotate by the driving motor 210. Alternatively, each air guiding vane 120 can also be connected to the transmission member 220, and each air guiding vane 120 is driven to rotate by the transmission member 220.

[0095] With such a setting, only by the cooperation of a driving motor 210 and a transmission member 220, the driving motor 210 not only drives the rotation of each air guiding vane 120 on the bearing plate 110, but also drives the movement of the bearing plate 110. The structure of the first driving assembly 200 is simpler, and the driving mode of the end adjusting assembly 100a is simplified. Moreover, there are no other driving components in the first driving assembly 200. The first driving assembly 200 as a whole occupies less space and is lighter in weight, which can save the space of the air guiding assembly 20, facilitate the layout design of other components in the air handling device 1, and is beneficial to the overall light weight of the air handling device 1. In addition, only by a first driving motor 210 driving the end adjusting assembly 100a to move, the number of the first driving motors 210 used is reduced to the greatest extent, and the energy consumption of the air guiding assembly 20 can be reduced.

[0096] Figure 6 The sectional view of the transmission member provided by the embodiment of the present application. Refer to Figure 6 As shown, in the first driving assembly 200, the transmission member 220 may include a first transmission portion 221 and a second transmission portion 222. The first transmission portion 221 is connected to the driving motor 210, and the second transmission portion 222 is drivingly connected between the first transmission portion 221 and the bearing plate 110. Among them, the driving motor 210 can directly drive the rotation of each air guiding vane 120, or the driving motor 210 drives each air guiding vane 120 to rotate through the first transmission portion 221. And, the driving motor 210 can transmit power to the first transmission portion 221, the first transmission portion 221 and the second transmission portion 222 drive each other, and finally drive the bearing plate 110 to move through the second transmission portion 222.

[0097] The first transmission portion 221 is directly connected to the driving motor 210. During the continuous operation of the driving motor 210, the first transmission portion 221 can also operate continuously. In this way, whether the driving motor 210 directly drives the rotation of each air guiding vane 120, or the driving motor 210 drives each air guiding vane 120 to rotate through the first transmission portion 221, the continuous rotation of each air guiding vane 120 can be realized.

[0098] By designing the architecture of the first transmission part 221 and the second transmission part 222, it is achieved that the first transmission part 221 can transmit power to the second transmission part 222, and the first transmission part 221 may not transmit power to the second transmission part 222. When the first transmission part 221 transmits power to the second transmission part 222, the second transmission part 222 operates, and the second transmission part 222 drives the bearing plate 110 to move. At this time, each wind guide blade 120 rotates relative to the bearing plate 110, and the bearing plate 110 also moves relative to the air outlet 12. When the first transmission part 221 does not transmit power to the second transmission part 222, the second transmission part 222 stops operating, and the second transmission part 222 limits the bearing plate 110 to the current position (for example, the initial position or the limit position). At this time, only each wind guide blade 120 rotates relative to the bearing plate 110, and the bearing plate 110 does not move.

[0099] Exemplarily, the second transmission part 222 can be located on a side of the first transmission part 221 close to the carrier plate 110. In this way, the first transmission part 221 and the second transmission part 222 are adjacent to each other, which facilitates the transmission of power between the two. The second transmission part 222 is also closer to the carrier plate 110, which facilitates the connection between the second transmission part 222 and the carrier plate 110. In addition, the first transmission part 221 and the second transmission part 222 are stacked, the volume of the transmission member 220 is smaller, the space occupied by the drive assembly 200 as a whole is smaller, and the degree of integration is higher.

[0100] It should be noted that the second transmission part 222 in this embodiment is located on the side of the first transmission part 221 close to the carrier plate 110, which does not limit the second transmission part 222 to be completely located on one side of the first transmission part 221. The second transmission part 222 and the first transmission part 221 may also have parts located in the same space to facilitate transmission cooperation between the second transmission part 222 and the first transmission part 221.

[0101] In this embodiment, the transmission member 220 connected between the first driving assembly 200 and the supporting plate 110 of the end adjustment assembly 100a can be a gear set 220a. The gear set 220a is used as the transmission member 220 to realize the transmission between the driving motor 210 and the supporting plate 110 through gear transmission.

[0102] The gear set 220a mainly realizes transmission by setting gears that mesh with each other and are coaxial, and is mainly used to drive the target structural member to rotate. In this way, the gear set 220a can drive the bearing plate 110 of the end adjustment assembly 100a to swing, so as to change the included angle of the bearing plate 110 in the length direction relative to the air outlet 12. Moreover, the gear set 220a is tightly matched, and the gears in the gear set 220a mesh, stack, and butt. The overall volume of the gear set 220a is small, which is beneficial to reducing the overall occupied space of the first driving assembly 200. In addition, the gear set 220a can achieve precise transmission, not only with high transmission efficiency but also high transmission accuracy, which can improve the driving accuracy of the first driving assembly 200 and make the accuracy of the air guiding assembly 20 for adjusting the air supply angle higher.

[0103] Of course, in other embodiments, the transmission member 220 can also be in other structural forms, and the transmission member 220 can transmit power through other transmission methods. For example, the transmission member 220 can be other transmission structures such as link transmission, telescopic rod transmission, and gear rack transmission. This embodiment does not limit this.

[0104] Figure 7 For Figure 6 the planar perspective view of the transmission member in. Refer to Figure 6 and Figure 7 As shown, the gear set 220a may specifically include a first gear pair 221a and a second gear pair 222a. The first gear pair 221a and the second gear pair 222a respectively correspond to the aforementioned first transmission part 221 and the second transmission part 222. The first gear pair 221a is in transmission connection with the driving motor 210. For example, the first gear pair 221a can be connected to the output shaft of the driving motor 210. The second gear pair 222a is in transmission connection between the first gear pair 221a and the bearing plate 110.

[0105] The second gear pair 222a can be located on the side of the first gear pair 221a close to the bearing plate 110, which is convenient for the transmission connection between the first gear pair 221a and the second gear pair 222a and for the connection between the second gear pair 222a and the bearing plate 110. In the thickness direction of the bearing plate 110, the second gear pair 222a and the first gear pair 221a can have parts located in the same thickness space to facilitate the transmission cooperation between the second gear pair 222a and the first gear pair 221a. Details are not described here again.

[0106] Among them, the gear set 220a can avoid the output shaft of the drive motor 210. The output shaft of the drive motor 210 is directly drivingly connected to each air guide vane 120, and the drive motor 210 drives each air guide vane 120 to continuously rotate. Alternatively, the first gear pair 221a is connected to the output shaft of the drive motor 210, and is drivingly connected to each air guide vane 120 by the first gear pair 221a, and the first gear pair 221a drives each air guide vane 120 to continuously rotate. The second gear pair 222a is drivingly connected to the carrier plate 110. When the first gear pair 221a drives the second gear pair 222a, the second gear pair 222a drives the carrier plate 110 to swing; when the first gear pair 221a does not drive the second gear pair 222a, the carrier plate 110 remains stationary.

[0107] Combined with Figure 6 and Figure 7 , the first gear pair 221a may include a driving wheel 2211, and the driving wheel 2211 is connected to the output shaft of the drive motor 210. The second gear pair 222a may include a first transmission wheel 2221, and the first transmission wheel 2221 is disposed on a side of the driving wheel 2211 close to the carrier plate 110. The first transmission wheel 2221 and the driving wheel 2211 are in driving cooperation, and the first transmission wheel 2221 is drivingly connected to the carrier plate 110.

[0108] After the drive motor 210 is started, the drive motor 210 can drive the driving wheel 2211 to continuously rotate. Through the transmission design of the driving wheel 2211 and the first transmission wheel 2221, during the rotation of the driving wheel 2211, it is realized that the driving wheel 2211 can drive the first transmission wheel 2221 to rotate, and the driving wheel 2211 can also not drive the first transmission wheel 2221 and the first transmission wheel 2221 remains stationary. For example, when the driving wheel 2211 rotates within a certain angle range, the driving wheel 2211 drives the first transmission wheel 2221 to rotate; when the driving wheel 2211 rotates within other angle ranges, the first transmission wheel 2221 remains stationary.

[0109] Continue to refer to Figure 6 and Figure 7 , as an implementation manner, the first transmission wheel 2221 and the driving wheel 2211 may be partially overlapped, and a transmission rod 22111 may be disposed on a side of the driving wheel 2211 facing the first transmission wheel 2221. A transmission groove 22211 may be formed on the first transmission wheel 2221, and the transmission groove 22211 may communicate with the side wall of the first transmission wheel 2221. When installing the first transmission wheel 2221, the transmission groove 22211 on the first transmission wheel 2221 is disposed facing the driving wheel 2211, so that the notch of the transmission groove 22211 is within the coverage range of the driving wheel 2211, and the notch of the transmission groove 22211 is on the circumferential path of the rotation of the transmission rod 22111 on the driving wheel 2211.

[0110] During the process of the driving motor 210 driving the driving wheel 2211 to rotate, the transmission rod 22111 on the driving wheel 2211 performs a circular motion. When the transmission rod 22111 on the driving wheel 2211 rotates to the notch position of the transmission groove 22211 on the first transmission wheel 2221, with the continuous rotation of the driving wheel 2211, the transmission rod 22111 will enter the transmission groove 22211. Moreover, the transmission rod 22111 will slide along the transmission groove 22211. During this period, under the external force exerted by the transmission rod 22111, the first transmission wheel 2221 will rotate synchronously with the driving wheel 2211. Thus, it is realized that the driving motor 210 or the driving wheel 2211 drives the air guide vane 120 to swing, and at the same time, the first transmission wheel 2221 drives the bearing plate 110 to swing.

[0111] With the continuous rotation of the driving wheel 2211, the transmission rod 22111 will disengage from the transmission groove 22211. After the transmission rod 22111 disengages from the transmission groove 22211, the first transmission wheel 2221 will no longer be subject to an external force, and the first transmission wheel 2221 will stop rotating and stay in the current position (at this time, the bearing plate 110 can stay in the limit position). After that, when the driving wheel 2211 continues to rotate in the original direction, the transmission rod 22111 will move away from the first transmission wheel 2221, and the notch of the transmission groove 22211 can no longer correspond to the transmission rod 22111, and the driving wheel 2211 will no longer drive the first transmission wheel 2221 to rotate.

[0112] If you want the driving wheel 2211 to drive the first transmission wheel 2221 to rotate again, the driving motor 210 can be rotated in the reverse direction to make the driving wheel 2211 rotate in the reverse direction. During the process of the driving wheel 2211 rotating in the reverse direction, the transmission rod 22111 on the driving wheel 2211 moves towards the first transmission wheel 2221, and the transmission rod 22111 can rotate to correspond to the notch of the transmission groove 22211. When the transmission rod 22111 enters the transmission groove 22211, during the process of the transmission rod 22111 sliding along the transmission groove 22211, it can drive the first transmission wheel 2221 to rotate again. At this time, the first transmission wheel 2221 also rotates in the reverse direction, and the first transmission wheel 2221 drives the bearing plate 110 to swing in the reverse direction so that the bearing plate 110 returns to the initial position.

[0113] Among them, the transmission groove 22211 can extend along the radial direction of the first transmission wheel 2221. During the process of the driving wheel 2211 driving the first transmission wheel 2221 to rotate, the movement trajectory of the transmission groove 22211 always matches the circumferential trajectory of the movement of the transmission rod 22111. That is to say, the center line in the width direction of the transmission groove 22211 always maintains a tangent state with the circumferential trajectory of the transmission rod 22111. In this way, it can be ensured that the transmission rod 22111 smoothly slides along the transmission groove 22211, and there will be no problems such as interference or jamming between the two, and the driving wheel 2211 can smoothly drive the first transmission wheel 2221 to rotate.

[0114] Continue to refer to Figure 6 and Figure 7 , the first gear pair 221a can also include a first driven wheel 2212, and the first driven wheel 2212 is coaxially arranged on the side of the driving wheel 2211 close to the bearing plate 110. In other words, the first driven wheel 2212 and the first transmission wheel 2221 can be arranged side by side in the same space. In this way, on the basis that only part of the first transmission wheel 2221 and the driving wheel 2211 overlap, the first driven wheel 2212 makes the gear set 220a have more overlapping parts, and the first driven wheel 2212 increases the weight of the gear set 220a, and the stability and reliability of the gear set 220a are higher.

[0115] There should be no interference between the first driven wheel 2212 and the first transmission wheel 2221, and there are no overlapping or lapping parts between the two. In this way, the rotation of the first driven wheel 2212 will not affect the rotation of the first transmission wheel 2221, so as to ensure that the driving wheel 2211 can smoothly drive the first transmission wheel 2221 to rotate.

[0116] As an implementation manner, the outer peripheral wall of the first transmission wheel 2221 can have at least one concave arc surface 22212, and the concave arc surface 22212 matches the outer circular surface of the first driven wheel 2212. In other words, the center of the circle of the circumference where the concave arc surface 22212 of the first transmission wheel 2221 is located should coincide with the center of the outer circular surface of the first driven wheel 2212. When assembling the gear set 220a, the transmission groove 22211 on the first transmission wheel 2221 faces the first driven wheel 2212. At the same time, the part of the outer peripheral wall of the first transmission wheel 2221 facing the first driven wheel 2212 should also be the concave arc surface 22212. While ensuring that the transmission rod 22111 can enter the transmission groove 22211, the concave arc surface 22212 of the first transmission wheel 2221 can cooperate with the outer circular surface of the first driven wheel 2212.

[0117] During the process of the driving wheel 2211 driving the first transmission wheel 2221 to rotate, the outer circumferential surface of the first driven wheel 2212 slides along the concave arc surface 22212 of the first transmission wheel 2221. In this way, there is no interference between the first driven wheel 2212 and the first transmission wheel 2221, and it does not affect the rotation of the first transmission wheel 2221. Moreover, there is a mutually cooperating friction surface between the first driven wheel 2212 and the second transmission wheel 2223, and a certain frictional force is generated between the two, which can make the movement of the first transmission wheel 2221 smoother and more reliable.

[0118] Exemplarily, there may be more than two concave arc surfaces 22212 on the outer peripheral wall of the first transmission wheel 2221, and the concave arc surfaces 22212 are evenly spaced along the circumferential direction of the first transmission wheel 2221. In this way, the contour of the first transmission wheel 2221 is more regular and has better symmetry. It is convenient for the processing and manufacturing of the first transmission wheel 2221. The transmission groove 22211 can be set corresponding to any concave arc surface 22212, which can reduce the processing difficulty of the first transmission wheel 2221 and improve the processing efficiency of the first transmission wheel 2221. Moreover, the structure of the first transmission wheel 2221 is more regular and has better stability. The volume of the first transmission wheel 2221 extending outside the driving wheel 2211 is smaller, and the overall operating reliability of the gear set 220a is higher.

[0119] Of course, on the premise of ensuring the operating reliability of the gear set 220a, only one concave arc surface 22212 may be provided on the outer peripheral wall of the first transmission wheel 2221, and the rest of the outer peripheral wall of the first transmission wheel 2221 is an outer circumferential surface. This embodiment does not make specific restrictions on this.

[0120] Since a transmission rod 22111 is provided on the surface of the driving wheel 2211 facing the first driven wheel 2212, in order to ensure that the transmission rod 22111 can reliably cooperate with the transmission groove 22211 of the first transmission wheel 2221, a relief recess 22121 may also be provided on the outer peripheral wall of the first driven wheel 2212. The relief recess 22121 is used to avoid the transmission rod 22111 on the driving wheel 2211. The transmission rod 22111 is located on the side of the relief recess 22121 to leave a certain space outside the circumference of the transmission rod 22111 to avoid interference with the cooperation between the transmission rod 22111 and the relief groove.

[0121] For example, the relief recess 22121 may be an arc-shaped concave surface, and the axis of the transmission rod 22111 may be located on the radial line of the arc-shaped concave surface. The distances from the axis of the transmission rod 22111 to both ends of the arc-shaped concave surface are equal. In this way, the transmission rod 22111 can be used as a positioning reference to position the first driven wheel 2212 when assembling the first driven wheel 2212 and the driving wheel 2211. Moreover, the first driven wheel 2212 and the driving wheel 2211 are symmetrically structured after assembly, and the appearance effect is better.

[0122] Continue to refer to Figure 6 and Figure 7 The second gear pair 222a may further include a second driven wheel 2222. The second driven wheel 2222 is coaxially arranged on the side of the first driving wheel 2221 close to the bearing plate 110, and the bearing plate 110 is in transmission connection with the second driven wheel 2222. In this way, the second driven wheel 2222 is closer to the bearing plate 110, which is convenient for the connection between the second gear pair 222a and the bearing plate 110.

[0123] Moreover, since the second driven wheel 2222 is coaxially arranged with the first driving wheel 2221, the second driven wheel 2222 rotates synchronously with the first driving wheel 2221. When the second driven wheel 2222 rotates synchronously with the first driving wheel 2221, it drives the bearing plate 110 to swing. When the second driven wheel 2222 is stationary with the first driving wheel 2221, the bearing plate 110 is limited to the initial position or the limit position, and the bearing plate 110 remains stationary.

[0124] On this basis, the second gear pair 222a may further include a second driving wheel 2223. The second driving wheel 2223 is arranged on the side of the first driven wheel 2212 close to the bearing plate 110. Moreover, the second driving wheel 2223 meshes with the second driven wheel 2222, and the bearing plate 110 is connected to the second driving wheel 2223, and the bearing plate 110 is driven to rotate by the second driving wheel 2223.

[0125] Among them, the transmission ratio between the second driving wheel 2223 and the second driven wheel 2222 may be inconsistent. In other words, the outer diameters of the second driving wheel 2223 and the second driven wheel 2222 may be different. In this way, by setting the second driving wheel 2223 to mesh with the second driven wheel 2222, the rotational speeds of the second driven wheel 2222 and the first driving wheel 2221 remain the same, but the rotational speeds of the second driving wheel 2223 and the second driven wheel 2222 are inconsistent. In this way, according to the required swinging speed of the bearing plate 110, the size of the second driven wheel 2222 can be selected to maintain an appropriate transmission ratio between the second driven wheel 2222 and the second driving wheel 2223, and the rotational speed of the second driving wheel 2223 is controlled within a suitable range to ensure the smooth swinging of the bearing plate 110.

[0126] Since the rotational speed output by the driving motor 210 is usually high, when transmitting power to the structural member, it is often necessary to reduce the speed and increase the torque of the driving motor 210 to meet the rotational requirements of the structural member. In this regard, the outer diameter of the second driving wheel 2223 may be larger than the outer diameter of the second driven wheel 2222, and the second driving wheel 2223 can play a role in reducing speed and increasing torque to enable the bearing plate 110 to maintain an appropriate swinging speed. Moreover, the torque between the second driving wheel 2223 and the bearing plate 110 is greater, which can make the movement of the bearing plate 110 more stable and reliable.

[0127] In addition to being able to adjust the output speed of the second gear pair 222a, the second transmission wheel 2223 is arranged on the first driven wheel 2212, and the second transmission wheel 2223 can also play a role in adjusting the overall center of gravity of the gear set 220a, making the overall gear set 220a more stable and reliable. Among them, the second transmission wheel 2223 and the first transmission wheel 2221 can partially overlap, and the two sides of the first transmission wheel 2221 are supported by the driving wheel 2211 and the second transmission wheel 2223, making the overall structure of the gear set 220a more stable.

[0128] In addition, in the intermediate adjustment assembly 100b, each air guiding assembly 20 can be rotatably connected to the bearing plate 110. Thus, by driving the rotation of the air guiding vanes 120 on the bearing plate of the intermediate adjustment assembly 100b, the deflection angle of the air guiding vanes 120 on the bearing plate 110 of the intermediate adjustment assembly 100b can be changed, and further the adjustment of the air supply angle in the intermediate adjustment assembly 100b can be realized.

[0129] On this basis, the air guiding assembly can further include N - 2 second driving assemblies, and the N - 2 second driving assemblies can be respectively connected to each intermediate adjustment assembly 100b. And the N - 2 second driving assemblies drive the respective air guiding vanes in the corresponding intermediate adjustment assembly 100b to rotate relative to the bearing plate.

[0130] In this way, under the drive of the first driving assembly, the end adjustment assembly 100a, and under the drive of the first driving assembly and the second driving assembly, the intermediate adjustment assembly 100b, each bearing plate can move relative to the air outlet and extend out of the air outlet. And each air guiding vane can move relative to the bearing plate. Thus, each adjustment assembly can adjust the air supply angle through the bearing plate extending out of the air outlet and the multiple air guiding vanes arranged on the bearing plate, can flexibly adjust the air supply angle of the air guiding assembly 20, expand the air supply area of the air guiding assembly 20, and improve the adjustment accuracy of the air guiding assembly 20 for the air supply area. In this way, by adjusting the air supply angle of the air guiding assembly 20 through the first driving assembly and the second driving assembly, the air supply area of the air guiding assembly 20 can be avoided from the user's activity area, and the discomfort or health problems caused by the cold air blowing directly on the user can be avoided. It is also possible to drive the air supply angle of the air guiding assembly 20 to change continuously through the first driving assembly 200, avoid the air guiding assembly 20 from blowing directly on a certain area for a long time, and improve the uniformity of the overall indoor temperature.

[0131] In some embodiments, for N adjustment assemblies, when N is odd, the intermediate adjustment assembly 100b may further include a central adjustment assembly 100c (see Figure 2 and Figure 3), the central adjustment component 100c is located at the center of the air outlet 12. Each air guide vane 120 in the central adjustment component 100c can be fixedly arranged on the bearing plate 110, and the leaf surface direction of the air guide vane 120 is the length direction of the bearing plate 110.

[0132] Based on this, the air guide component 20 includes N - 3 second driving components, and the second driving components can drive each air guide vane in the corresponding intermediate adjustment component 100b to rotate relative to the bearing plate.

[0133] For the structural design of the second driving components, reference can be made to the structural design of the foregoing first driving component 200, as long as it can realize the movement of each air guide vane 120 on the bearing plate 110 of the intermediate adjustment component 100b, which will not be elaborated here.

[0134] In this way, the air guide vanes 120 of the central adjustment component 100c can be fixedly arranged on the bearing plate 110, and the leaf surface direction of the air guide vanes 120 is the length direction of the bearing plate 110. In this way, each air guide vane 120 of the central adjustment component 100c can form a directional flow guiding structure for the air flow in the central area of the air outlet 12. Through the blocking and guiding effects of the air guide vanes 120, most of the air flow in the central area can be guided along the length direction of the air outlet 12 to both ends of the air outlet 12, and flows out after being guided by the end adjustment component 100a and the remaining intermediate adjustment components 100b. The central adjustment component 100c only allows a small part of the air flow to flow out from the gaps between the adjacent air guide vanes 120 of the central adjustment component 100c, which can effectively avoid the problems of too strong local air flow velocity or uneven temperature distribution in the central area of the air outlet 12, and significantly improve the air supply uniformity in the central area of the air outlet 12.

[0135] In some other embodiments, when N is an odd number greater than or equal to 5, N - 2 intermediate adjustment components 100b include a central adjustment component 100c located at the center position of the air outlet. At this time, the air guide component 20 can only include one first driving component 200, and the first driving component 200 includes a first driving part, and the first driving part can be connected to the central adjustment component 100c and drive the bearing plate of the central adjustment component 100c to translate in and out relative to the air outlet.

[0136] Based on this, the length direction of the bearing plate 110 of the central adjustment component 100c can always be consistent with the length direction of the air outlet 12. The bearing plate 110 of the central adjustment component 100c can translate on the basic air duct wall 13 along the width direction of the air outlet 12, and further change the position of the bearing plate 110 of the second adjustment component 100b relative to the air outlet 12.

[0137] For example, the carrier plate 110 of the central adjustment component 100c can move in the direction towards the air outlet 12 from its position housed in the air duct. For example, the carrier plate 110 of the central adjustment component 100c moves to the plane where the air outlet 12 is located, and even the entire carrier plate 110 of the central adjustment component 100c extends outside the air outlet 12. Or, the carrier plate 110 of the central adjustment component 100c moves from a position in or outside the plane where the air outlet 12 is located towards the air duct, so that the carrier plate 110 of the central adjustment component 100c is retracted into the air duct.

[0138] Regarding the structural design of the first driving part, the precise in-and-out translation drive of the carrier plate 110 of the central adjustment component 100c can be achieved through the combination of a stepper motor and a transmission chain.

[0139] Among them, the stepper motor can be installed on the carrier plate 110 of the central adjustment component 100c and can provide driving force for the movement of the transmission chain to ensure the directness and efficiency of power transmission. And, the output shaft of the stepper motor can be in transmission connection with the transmission chain through a gear or a sprocket.

[0140] The transmission chain is arranged at the air outlet 12 and can be installed on the basic air duct wall 13, and the transmission chain can expand and contract in a direction perpendicular to the air outlet 12. For example, the transmission chain can be slidably connected to a slideway provided on the basic air duct wall 13, and the slideway extends along the length direction perpendicular to the air outlet 12. When the transmission chain moves under the drive of the stepper motor, it can slide along the slideway and can be extended and retracted relative to the air outlet 12.

[0141] The stepper motor can be electrically connected to the control component in the air guiding component 20. For example, the control component is connected to the stepper motor through a signal line, or there is a wireless communication connection between the control component and the stepper motor. By controlling the operation of the stepper motor through the control component, it is convenient to control the movement of the carrier plate 110 of the central adjustment component 100c, so as to achieve precise regulation of the air supply area of the central adjustment component 100c.

[0142] Specifically, when the air handling device 1 needs to drive the carrier plate 110 of the central adjustment component 100c to move, the control component will send a corresponding signal to the stepper motor. After receiving the signal, the stepper motor starts to rotate according to the preset rotation angle and speed. As the stepper motor rotates, the sprocket connected to it will also rotate synchronously, and the rotation of the sprocket drives the transmission chain meshed with it to move in a direction perpendicular to the air outlet 12. Since the stepper motor is installed on the carrier plate 110 of the central adjustment component 100c, the stepper motor can be driven by the chain to expand and contract in a direction perpendicular to the air outlet 12 together, and then can drive the carrier plate 110 to translate in and out relative to the air outlet 12.

[0143] For example, when the stepper motor rotates forward to drive the sprocket, the transmission chain can be moved outward from the air outlet 12, and the transmission chain drives the stepper motor and the carrier plate 110 connected thereto to translate outward from the air outlet 12. When the stepper motor rotates in reverse to drive the sprocket to rotate in the opposite direction, the transmission chain contracts relative to the air outlet 12, pushing the stepper motor and the carrier plate 110 to translate inward into the air outlet 12.

[0144] In this way, through the cooperation of the transmission chain and the stepper motor, efficient and reliable power transmission can be achieved to ensure the stability and efficiency of the telescopic movement of the carrier plate 110 of the central adjustment assembly 100c in the direction perpendicular to the air outlet 12. Moreover, since the transmission chain has high strength and rigidity, the above structure can provide sufficient power and load-bearing capacity for the inward and outward translation of the carrier plate 110 of the central adjustment assembly 100c.

[0145] In addition, due to the flexible arrangement of the transmission chain and the small size of the stepper motor, the two can cooperate to form a relatively compact telescopic mechanism, which can flexibly adapt to the requirements of different spaces, is convenient to be installed in a limited space, and is beneficial to the miniaturization and lightweight design of the air treatment equipment.

[0146] As another implementation manner, the first driving part can also be the cooperation of a stepper motor and a rack and pinion. Among them, a rack can be fixedly arranged at the air outlet 12, and the rack extends in the direction perpendicular to the air outlet 12. The stepper motor is installed on the carrier plate 110 of the central adjustment assembly 100c, and the stepper motor can drive the gear to rotate. When the gear rotates, the gear meshes with the rack, and the gear can drive the stepper motor connected thereto to move outward or inward from the air outlet 12, so as to realize the inward and outward translation of the carrier plate 110 of the central adjustment assembly 100c relative to the air outlet 12.

[0147] In this way, through the inward and outward translation of the carrier plate 110 of the central adjustment assembly 100c relative to the air outlet 12, the air outlet condition in the central area of the air outlet 12 can be flexibly adjusted. When the carrier plate 110 of the central adjustment assembly 100c translates inward, the air outlet area in the central area can be reduced, making the air more concentrated and enhancing the air supply intensity. When the carrier plate 110 of the central adjustment assembly 100c translates outward, the air outlet can be enlarged to disperse the air flow.

[0148] Since the carrier plates 110 of the respective adjustment assemblies are movably connected to each other, when the central adjustment assembly 100c translates inward and outward relative to the air outlet, it can drive the other adjustment assemblies to move in cooperation.

[0149] It can be understood that the air guiding vanes 120 on the central adjusting assembly 100c can be fixed on the bearing plate 110 with an unchanged relative position to the bearing plate 110, or the air guiding vanes 120 on the central adjusting assembly 100c can also be rotatably connected to the bearing plate 110. Here, no limitation is made on whether relative movement occurs between the air guiding vanes 120 on the central adjusting assembly 100c and the bearing plate 110.

[0150] When the air guiding vanes in the central adjusting assembly 100c are rotatably connected to the bearing plate, at this time, the first driving assembly further includes a second driving part, and the second driving part can drive the air guiding vanes in the central adjusting assembly 100c to rotate relative to the bearing plate.

[0151] On this basis, the air guiding assembly further includes N - 1 second driving assemblies. The second driving assemblies are respectively connected to the other adjusting assemblies except the central adjusting assembly 100c, and the second driving assemblies can drive the air guiding vanes in the corresponding adjusting assemblies to rotate relative to the bearing plate.

[0152] Among them, the structural designs of the second driving part and the (N - 1)th second driving assembly can both refer to the design of the foregoing first driving assembly, which will not be elaborated here.

[0153] It should be noted that the bearing plates 110 in each group of adjusting assemblies 100 are sequentially movably connected along the length direction of the air outlet to realize the coordinated movement of the bearing plates 110 of each adjusting assembly 100. The following describes the movable connection method of the bearing plates 110 of each adjusting assembly 100. For the convenience of description, in this embodiment, the inner end 111 of the bearing plate 110 is defined as the end of the bearing plate 110 facing the inside of the air outlet 12, and the outer end 112 of the bearing plate 110 is defined as the end of the bearing plate 110 facing the outside of the air outlet 12 (see Figure 3 as shown).

[0154] When each adjusting assembly 100 is linearly arranged along the length direction of the air outlet, the bearing plates 110 of each adjusting assembly 100 are closely arranged to form a continuous air guiding plane. When all the adjusting assemblies 100 move outward along the direction of the air outlet 12 in an arc shape, the distance between the inner ends 111 of at least some adjacent bearing plates 110 will increase. At the same time, the distance between the outer ends 112 of all adjacent bearing plates 110 also increases. If only a single rotational connection method is used for the inner ends 111 and the outer ends 112 of each bearing plate 110, this rigid constraint will prevent the bearing plate 110 from adapting to the change in the distance, which may cause structural deformation or even damage to the bearing plate, thereby affecting the normal operation of the air guiding assembly 20.

[0155] Therefore, in this embodiment, the inner ends 111 of the bearing plates 110 of at least some adjacent adjusting components 100 are rotationally and slidably connected. The outer ends 112 of the bearing plates 110 of all adjacent adjusting components 100 are rotationally and slidably connected. In this way, the rotational and sliding connection method can endow the bearing plates 110 of each adjusting component 100 with translational freedom in the width direction of the air outlet 12, so that when the bearing plates 110 of each adjusting component 100 rotate outwards relative to the air outlet, they can linearly slide along a specific direction, thereby ensuring that the bearing plates 110 of each adjusting component 100 can cooperate smoothly and move along the expected trajectory, avoiding the bearing plates 110 of each adjusting component 100 from being stuck due to movement interference and unable to operate normally. Thus, each adjusting component 100 can flexibly and stably realize the movement relative to the air outlet 12, effectively improving the coordination and reliability of the operation of the air handling device 1.

[0156] In addition, in order to synchronously swing all the air guiding vanes 120 on the same bearing plate 110, as an implementation manner, at least some of the adjusting components 100 may further include a linkage mechanism to realize the coordinated movement of multiple air guiding vanes 120 on the same bearing plate 110 through mechanical coupling. In the embodiment of the present application, taking the first driving component 200 driving all the air guiding vanes 120 on the bearing plate 110 of the end adjusting component 100a to swing as an example for illustration.

[0157] Figure 8 It is an exploded view of an adjusting component provided in the embodiment of the present application. Refer to Figure 8 As shown, the end adjusting component 100a further includes a linkage member 130, and all the air guiding vanes 120 of the end adjusting component 100a are connected to the linkage member 130. When the first driving component 200 operates, it can drive the linkage member 130 to move. When the linkage member 130 moves, it can drive all the air guiding vanes 120 on the bearing plate 110 to move synchronously, so as to drive all the air guiding vanes 120 to swing synchronously through the linkage member 130.

[0158] Among them, the first driving component 200 can be connected to one of all the air guiding vanes 120 of the end adjusting component 100a. For example, the first driving component 200 is connected to the air guiding vane 120 located at the end of the bearing plate 110. The first driving component 200 drives the air guiding vane 120 to rotate, and the air guiding vane 120 drives the connected linkage member 130 to move. Furthermore, through the movement of the linkage member 130, all the air guiding vanes 120 are driven to swing synchronously.

[0159] Alternatively, the first driving component 200 can also be connected to the linkage 130. For example, the first driving component 200 is connected to a portion of the linkage 130 located between two air guiding vanes 120. The first driving component 200 drives the linkage 130 to move, and the linkage 130 drives all the air guiding vanes 120 to swing synchronously.

[0160] Continue to refer to Figure 8 As shown, the linkage 130 can be arranged inside the carrier plate 110. In this way, it is convenient for the linkage 130 to be connected to all the air guiding vanes 120. Moreover, the linkage 130 is also shielded inside the carrier plate 110, making the appearance of the air guiding assembly 20 more concise. In addition, the linkage 130 does not occupy an extra separate space and has no impact on the volume of the air guiding assembly 20, which is beneficial to the miniaturization of the air guiding assembly 20.

[0161] Among them, in order to install the linkage 130 inside the carrier plate 110 and facilitate the connection between the linkage 130 and each air guiding vane 120. The carrier plate 110 can be divided into two parts, a panel 113 and a bottom plate 114. All the air guiding vanes 120 can be installed on the panel 113, and the first driving component 200 can be installed on the bottom plate 114. Moreover, the first driving component 200 passes through the bottom plate 114 and is connected to the air guiding vane 120 or the linkage 130. The panel 113 and the bottom plate 114 jointly enclose a receiving cavity, and the linkage 130 is arranged inside the receiving cavity.

[0162] As an example, the linkage 130 can be a connecting rod 130a (see Figure 8 shown). The connecting rod 130a can extend along the extending direction of the carrier plate 110, and the connecting rod 130a is connected to all the air guiding vanes 120. The driving motor can drive one of the air guiding vanes 120 to rotate. The air guiding vane 120 drives the connecting rod 130a to reciprocate with a small swing amplitude. Through the swing and reciprocating motion of the connecting rod 130a, all the air guiding vanes 120 are driven to swing. Alternatively, the output shaft of the driving motor is connected to the connecting rod 130a. The driving motor rotates to drive the connecting rod 130a to reciprocate with a small swing amplitude, thereby driving all the air guiding vanes 120 to swing.

[0163] By setting the linkage 130 as the connecting rod 130a, the structure of the linkage 130 can be simplified. The processing technology of the linkage 130 is simple and the production cost is low, which is suitable for large-scale production and application. Moreover, the connecting rod 130a is a simple and reliable transmission structure, which can effectively convert the rotational motion of the driving motor into the linear reciprocating swing of the connecting rod 130a itself, helping to improve the reliability and durability of the adjusting component 100. In addition, the geometric characteristics of the connecting rod 130a determine that it can provide precise motion control, and can drive the air guiding vane 120 to make precise angular adjustments within a set range, so as to provide more precise air supply control for users.

[0164] The following provides a detailed description of the air guiding vane 120 provided in the embodiments of the present application.

[0165] Figure 9 It is a three-dimensional structure diagram of an air guiding vane provided in the embodiments of the present application. Refer to Figure 9 As shown, in this embodiment, the thickness of the vane body 121 can be between 2 mm and 3 mm. In this way, the vane body 121 has a certain thickness, meeting the processability requirements of the vane body 121 and being able to ensure the required structural strength of the vane body 121. At the same time, the thickness of the vane body 121 is also small, the space occupied by the vane body 121 is small, and there is sufficient spacing between adjacent vanes, so that the air flow in the air duct can be smoothly guided out, avoiding affecting the air outlet of the air handling equipment.

[0166] In order to enhance the flexibility of the adjustment assembly 100 to adjust the air supply area and further expand the air supply coverage area of the air guiding assembly 20, as an example, the shape of the air guiding vane 120 can also be designed as a curved surface shape. In this embodiment, the vane body 121 of at least part of the air guiding vanes 120 in the adjustment assembly 100 is set as a curved surface shape.

[0167] Taking the air guiding vane 120 of the end adjustment assembly 100a as an example, in this embodiment, the vane body 121 of the air guiding vane 120 of the end adjustment assembly 100a is set as a curved surface shape. In this way, an air guiding channel 123 is formed between the vane bodies 121 of adjacent air guiding vanes 120 in the end adjustment assembly 100a. Since the vane body 121 is in a curved surface shape, the Coanda effect can be generated on the air flow passing through the air guiding channel 123, changing the flow direction of the air flow. Furthermore, the air supply direction of the end adjustment assembly 100a is changed, and the air supply area of the air guiding assembly 20 is adjusted.

[0168] The so-called Coanda effect, also known as the wall attachment effect or the Coandă effect, is a phenomenon in fluid mechanics. Specifically, it is manifested as that during the flow process of a fluid (water flow or air flow), it will deviate from the original flow direction and instead flow along the surface of a convex object. When there is surface friction (or fluid viscosity) between the fluid and the surface of the object it flows through, as long as the curvature is not large, the fluid will flow along the surface of the object.

[0169] Specifically, the curvature profile of the blade body 121 of the air guide vane 120 in the end adjustment assembly 100a is aerodynamically optimized, and its convex outer surface can provide a flow path for the air flow that meets the conditions of the Coanda effect. When the air flow enters the air guide channel 123 formed by adjacent blade bodies 121, it first contacts the convex surface of the curved blade. Constrained by the viscous force and the curvature of the curved surface, the air flow can flow along the blade curved surface and shoot out along the tangent direction of the curved surface at the end of leaving the blade body 121, forming an air flow trajectory with a specific diffusion angle. Compared with the straight air flow or edge separation phenomenon caused by the flat blade, setting the blade body 121 as a curved surface shape can significantly increase the deflection angle of the air flow flowing out of the air guide channel 123 through the Coanda effect, and the air flows in adjacent air guide channels 123 form a cooperative diffusion effect under the guidance of the curved surface, thereby constructing a wider air supply coverage area.

[0170] A number of air outlets 12 may also be provided on the blade body 121. Taking the air guide vane 120 of the end adjustment assembly 100a as an example, a number of air outlet holes 124 may also be distributed on the blade body 121 of the air guide vane 120. The air outlet holes 124 penetrate through the two side surfaces of the blade body 121 in the thickness direction. When the blade body 121 is the aforementioned curved surface shape, a number of air outlet holes 124 may be provided on the blade body 121. Of course, when the blade body 121 is a flat surface shape, a number of air outlet holes 124 may also be provided on the blade body 121.

[0171] By providing a number of air outlet holes 124 on the blade body 121, when the air handling device 1 is in operation, the air flow blown out from the air duct can flow outwards through the air outlet holes 124 on the blade body 121.

[0172] Specifically, when the air guide vane 120 is in the open state, there is an angle between the air guide vane 120 and the plane where the air outlet 12 is located, and an air guide channel 123 is formed between adjacent air guide vanes 120. At this time, part of the air flow blown out from the air duct will flow outwards along the air guide channel 123, and part of it can also flow outwards through the air outlet holes 124 on the blade body 121. In this way, the air supply effect of the air handling device 1 is improved by using the air outlet holes 124 on the blade body 121.

[0173] When the air handling device 1 supplies air outwards through the end adjustment assembly 100a, in addition to generating a first air flow flowing outwards along the air guide channel 123, it will also generate a second air flow flowing outwards through the air outlet holes 124, and the flow direction of the second air flow is different from that of the first air flow. Under the impact of the second air flow on the first air flow, the flow rate of the first air flow can be slowed down, avoiding strong wind blowing out from the air outlet 12, making the air supply effect of the air handling device 1 softer and improving the use comfort of the air handling device 1.

[0174] It should be noted that the aperture of the air outlet holes 124 formed in the blade body 121 is very small, and the air flow in the air duct will still preferentially flow outwards through the air guiding channels 123 between the adjacent air guiding blades 120. Therefore, most of the air flow in the air duct will flow out through the air guiding channels 123 between the adjacent air guiding blades 120, and only a small part of the air flow will flow out through the air outlet holes 124. This small part of the air flow passing through the air outlet holes 124 can play a good role in counteracting and mixing the air flow, and can weaken the air flow velocity of the air outlet. At the same time, it will not have too much impact on the overall air supply direction and air supply area of the end adjusting component 100a, and can ensure the air supply adjustment effect of the end adjusting component 100a.

[0175] When the air guiding blades 120 are in the closed state, the air guiding blades 120 are generally parallel to the plane where the air outlet 12 is located. Each air guiding blade 120 of the end adjusting component 100a can be located on the same straight line, and there is only a tiny installation gap between the adjacent air guiding blades 120. At this time, the air flow blown out from the air duct basically flows outwards through the air outlet holes 124 on the blade body 121. Since the aperture of the air outlet holes 124 is very small and the opening area of the blade body 121 is limited, the flow rate of the air flow flowing out from the air outlet holes 124 of each air guiding blade 120 is small, the air supply volume of the air handling device 1 is small, and the air flow velocity is low.

[0176] Exemplarily, when the air handling device 1 is heating, the air guiding blades 120 can be in the closed state, and only rely on the air outlet holes 124 on each air guiding blade 120 to convey hot air outwards. Since the flow velocity of the hot air is low and the air resistance of the blade body 121 to the hot air is small, the hot air can be stably output outwards through the air outlet holes 124 on the blade body 121. Moreover, only by outputting hot air through the air outlet holes 124 on the blade body 121, the flow rate of the hot air can be restricted, so that the indoor space can be maintained at a suitable temperature and the energy consumption of the air handling device 1 can be reduced.

[0177] Among them, the plurality of air outlet holes 124 can be evenly distributed on the surface of the blade body 121. In this way, it can be ensured that there is sufficient opening area on the blade body 121, so that the second air flow flowing out through the air outlet holes 124 has sufficient air volume, ensuring that the second air flow can effectively play a role in weakening the flow velocity of the first air flow, and realizing the softening of the air supply of the air handling device 1. And since the air outlet holes 124 are evenly distributed in each area of the blade body 121, the pressure action of the second air flow on the blade body 121 is evenly distributed on the blade body 121, and the stress uniformity of the blade body 121 is good, which can improve the reliability and service life of the blade body 121.

[0178] Exemplarily, the air outlet holes 124 may be arranged in an array on the surface of the blade body 121. Along the height direction of the blade body 121 (the height direction of the blade body 121 is, for example, the width direction of the air outlet holes 124), there are multiple rows of air outlet holes 124 arranged in sequence. Each row of air outlet holes 124 includes a plurality of air outlet holes 124 arranged in sequence along the width direction of the blade body 121. The adjacent two rows of air outlet holes 124 may be arranged staggeredly, wherein the air outlet holes 124 in one row may be correspondingly located between two adjacent air outlet holes 124 in the other row.

[0179] In addition, continue to refer to Figure 2 As shown, the air handling device 1 further includes an evaporator 14 and a blower 15. The evaporator 14 and the blower 15 are both arranged in the housing 11. In addition, the air handling device may further include an outdoor unit (not shown in the figure), and a condenser and a compressor are arranged in the outdoor unit. The outdoor unit is communicated with the device body 10 through a pipeline.

[0180] Among them, the blower 15 can push the air to flow, circulate the indoor air, and let the air flow through the evaporator 14 or the condenser for heat exchange, so as to realize the indoor temperature adjustment and ensure the uniform distribution of the temperature. The evaporator 14 and the condenser can be communicated through a refrigerant circuit, and the compressor is arranged on the refrigerant circuit. The compressor can realize the circulation of the refrigerant between the evaporator 14 and the condenser.

[0181] As an implementation manner, the evaporator 14 may be arranged in the coverage area of the second adjustment component 100b of the air guiding component 20. Since the coverage area of the second adjustment component 100b of the air guiding component 20 is the middle area of the housing 11, correspondingly, the evaporator 14 may be arranged in the middle area in the length direction of the housing 11.

[0182] In this way, the evaporator 14 can make the air flow more evenly on both sides of it, forming a relatively symmetrical flow field. This can avoid large disorders or deflection phenomena in the air flow, make the air flow through the evaporator 14 for heat exchange more smoothly, and then flow out smoothly from the air outlet 12, further improving the uniformity and stability of the air supply, reducing the uneven distribution of the indoor air flow and the generation of local eddies, and creating a more comfortable indoor air environment for users.

[0183] Moreover, the flow rate and flow velocity of the air flow drawn into the housing by the blower from the indoor are usually the largest in the middle area. Arranging the evaporator in the middle area can also quickly cool most of the air flow, and then flow out from the air outlet, achieving a better cooling effect.
