Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0041] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] The following is for reference. Figures 1-4 A fan blade assembly 200 according to an embodiment of the present invention is described.

[0043] Combination Figures 1 to 4 According to the present invention, the wind turbine assembly 200 includes: a plurality of wind turbines 210, which are arranged sequentially at intervals in the axial direction; and a connecting assembly 220, which includes a first connecting shaft 221, which is coaxially arranged with the wind turbines 210 and disposed between two adjacent wind turbines 210, and the two ends of the first connecting shaft 221 are respectively fixedly and non-detachably connected to the two wind turbines 210.

[0044] Specifically, multiple impellers 210 are arranged along the axial direction, and a first connecting shaft 221 is arranged between every two adjacent impellers 210. The first connecting shaft 221 is coaxial with the impellers 210, that is, impellers 210 are arranged at both ends of the first connecting shaft 221. Two adjacent impellers 210 can be fixedly connected by the first connecting shaft 221, and the first connecting shaft 221 and the impellers 210 are not detachable.

[0045] In related technologies, adjacent wind turbines are fixedly connected by connecting shafts and couplings, which results in complex components and numerous installation steps for the wind turbine assembly, affecting the production and assembly efficiency of the wind turbine assembly and leading to high production costs.

[0046] This application simplifies the component arrangement of the wind turbine assembly 200 by setting a first connecting shaft 221 between two adjacent wind turbines 210, and the first connecting shaft 221 can be directly and non-detachably fixedly connected to the wind turbines 210 located at both ends, without the need for a coupling. This effectively reduces the production cost of the wind turbine assembly 200, simplifies the installation process of the wind turbine assembly 200, and improves the production and installation efficiency of the wind turbine assembly 200.

[0047] According to the present invention, the wind turbine assembly 200 simplifies the component arrangement of the wind turbine assembly 200 by making the first connecting shaft 221 directly and non-detachably fixedly connected to the wind turbine 210 located at both ends of its axial direction, effectively reducing the production cost of the wind turbine assembly 200, and also simplifies the installation process of the wind turbine assembly 200 and improves the installation efficiency of the wind turbine assembly 200.

[0048] In some embodiments of the present invention, there are at least three wind turbines 210, and the multiple wind turbines 210 are arranged at equal intervals in the axial direction.

[0049] Specifically, at least three wind turbines 210 are provided. For example, the wind turbine assembly 200 can be provided with three wind turbines 210, four wind turbines 210, etc., to improve the air delivery capacity of the wind turbine assembly 200. Each pair of wind turbines 210 is fixedly connected by a first connecting shaft 221, which helps to ensure the coaxiality between multiple wind turbines 210.

[0050] Furthermore, multiple impellers 210 are arranged at equal intervals in the axial direction to ensure the uniformity of airflow from the impeller assembly 200 and improve the airflow performance of the impeller assembly 200.

[0051] It is understandable that the number of wind turbines 210 can be determined according to the actual air output requirements, and no specific limit is made here.

[0052] Combination Figure 3 and Figure 4 In some embodiments of the present invention, the connecting assembly 220 further includes a second connecting shaft 222, which is disposed on one side of the plurality of impellers 210 in the axial direction, and is coaxially arranged and connected with the impeller 210 located at the end in the arrangement direction. The second connecting shaft 222 is used for power connection with the motor 300.

[0053] Specifically, multiple impellers 210 and the first connecting shaft 221 are coaxially arranged in the axial direction. The second connecting shaft 222 is connected to the side of the impeller 210 located at the axial end that is away from the first connecting shaft 221. The motor 300 is arranged on the same side as the second connecting shaft 222, and the motor 300 can drive the second connecting shaft 222 to rotate. The second connecting shaft 222 can drive the impeller 210 connected to it to rotate. The multiple impellers 210 are fixedly connected through the first connecting shaft 221, so that the motor 300 can drive the multiple impellers 210 to rotate synchronously.

[0054] In related technologies, the motor is positioned between two impellers, resulting in a greater distance between the impellers on both sides of the motor than between other adjacent impellers. This means that the distances between multiple impellers are different, affecting the uniformity of airflow from the impeller assembly.

[0055] This application connects multiple impellers 210 via a first connecting shaft 221, and the motor 300 is located on one side of the multiple impellers 210 in the axial direction. This facilitates the assembly of the multiple impellers 210 while ensuring that the spacing between the multiple impellers 210 is the same, thereby further ensuring the uniformity of the airflow from the impeller assembly 200.

[0056] Furthermore, the second connecting shaft 222 is coaxially arranged with the multiple wind turbines 210, which helps to ensure the effect of the second connecting shaft 222 driving the multiple wind turbines 210 to rotate, and also helps to reduce the risk of breakage at the connection between the second connecting shaft 222 and the wind turbines 210.

[0057] Combination Figure 3 and Figure 4 In some embodiments of the present invention, a flexible connector 230 is provided at the axial end of the second connecting shaft 222 away from the impeller 210, and the flexible connector 230 is connected between the second connecting shaft 222 and the motor 300.

[0058] Specifically, the second connecting shaft 222 is connected to the motor 300 through the flexible connector 230 to achieve a flexible connection between the second connecting shaft 222 and the motor 300, effectively preventing the second connecting shaft 222 from vibrating, reducing the wear and vibration noise of the second connecting shaft 222, thereby preventing the impeller 210 from vibrating and reducing the noise generated when the fan blade assembly 200 is working.

[0059] like Figure 3 As shown, in some embodiments of the present invention, the axial end of the second connecting shaft 222 away from the wind turbine 210 is provided with a transmission shaft section 2221, and the flexible connector 230 is constructed as a rubber coupling, which is connected to the transmission shaft section 2221 and the motor 300 shaft of the motor 300 respectively.

[0060] Specifically, the end of the drive shaft section 2221 away from the impeller 210 is connected to a rubber coupling, and the end of the motor shaft 300 close to the impeller 210 is connected to a rubber coupling. By setting the rubber coupling, it is easy to achieve the centering installation of the drive shaft end and the motor shaft 300, ensuring the transmission effect. In addition, the rubber coupling can effectively absorb vibration and shock, and reduce the noise generated by vibration.

[0061] Optionally, the drive shaft section 2221 can be integrally formed with the second connecting shaft 222 to simplify the assembly process of the fan blade assembly 200; the drive shaft section 2221 can be separately formed and connected with the second connecting shaft 222 to facilitate the processing of the second connecting shaft 222 and the drive shaft section 2221, effectively reducing the processing difficulty of the second connecting shaft section 222 and the drive shaft section 2221.

[0062] Reference Figure 4 In some embodiments of the present invention, the flexible connector 230 is constructed as a rubber insert, which is embedded in the second connecting shaft 222 and connected to the motor 300 shaft of the motor 300.

[0063] Specifically, the end of the second connecting shaft 222 facing away from the impeller 210 is open. A rubber insert is embedded in the open end of the second connecting shaft 222 and is fixedly connected to the second connecting shaft 222. The motor shaft of the motor 300 can be inserted into the rubber insert and connected to the rubber insert, so that the motor shaft can be flexibly connected to the second connecting shaft 222 through the rubber insert to prevent the impeller 210 from vibrating and to reduce the noise generated when the fan blade assembly 200 is working.

[0064] Furthermore, since the rubber insert is embedded in the second connecting shaft 222, the second connecting shaft 222 can provide a mounting position for the rubber insert. There is no need to design assembly space for the rubber insert in the axial direction, which helps to shorten the axial dimension of the fan blade assembly 200 and reduce the axial space required to arrange the fan blade assembly 200.

[0065] Combination Figures 1 to 4 In some embodiments of the present invention, the connecting assembly 220 further includes a third connecting shaft 223, which is disposed on the other side of the plurality of impellers 210 in the axial direction, and is coaxially arranged and connected with the impeller 210 located at the other end in the arrangement direction. The third connecting shaft 223 is used to connect and cooperate with the support member.

[0066] Specifically, multiple impellers 210 and a third connecting shaft 223 are coaxially arranged in the axial direction. The third connecting shaft 223 is connected to the impeller 210 located at the end of the multiple impellers 210 that is away from the second connecting shaft 222. The third connecting shaft 223 is connected to the side of the impeller 210 away from the first connecting shaft 221. The third connecting shaft 223 is connected and cooperated with a support (e.g., a bearing or support seat) to facilitate the rotation of the third connecting shaft 223 and reduce the wear of the third connecting shaft 223.

[0067] Furthermore, the first connecting shaft 221, the second connecting shaft 222, the third connecting shaft 223, and the multiple impellers 210 are coaxially arranged, which helps to ensure the rotation effect of the impeller assembly 200 and can prevent the impeller assembly 200 from breaking due to shear force during rotation.

[0068] Combination Figures 1 to 4 In some embodiments of the present invention, a support shaft 2231 is provided at the axial end of the third connecting shaft 223 away from the impeller 210. The support shaft 2231 is used to connect and cooperate with the support member. For example, a bearing can be provided on the support shaft 2231. When the motor 300 drives multiple impellers 210 to rotate, the impellers 210 drive the third connecting shaft 223 and the support shaft 2231 to rotate. The bearing can support the rotation of the support shaft 2231 and reduce the friction when the support shaft 2231 rotates, making the rotation of the support shaft 2231 smoother.

[0069] Optionally, the support shaft 2231 can be integrally formed with the third connecting shaft 223 to simplify the assembly process of the fan blade assembly 200; the support shaft 2231 can be separately formed and connected with the third connecting shaft 223 to facilitate the processing of the third connecting shaft 223 and the support shaft 2231, effectively reducing the processing difficulty of the third connecting shaft 223 and the support shaft 2231.

[0070] Combination Figure 2 and Figure 3 In some embodiments of the present invention, the first connecting shaft 221 is provided with a first positioning part 2211 at both ends. The first positioning part 2211 is used to position and cooperate with the wind turbine 210 so as to facilitate the positioning and installation of the first connecting shaft 221 and the wind turbine 210, which helps to ensure the coaxiality between the first connecting shaft 221 and the multiple wind turbines 210, and ensure the assembly accuracy of the wind blade assembly 200.

[0071] Combination Figure 2 and Figure 3 In some embodiments of the present invention, the first positioning part 2211 is constructed as a positioning groove, and the impeller 210 is provided with a positioning protrusion 211, and the positioning groove and the positioning protrusion 211 are positioned and engaged.

[0072] Specifically, the positioning groove is recessed into the first connecting shaft 221 at its end along the axial direction. The impeller 210 has positioning protrusions 211 formed on both end faces along the axial direction. The positioning protrusions 211 extend away from the impeller 210 along the axial direction. The positioning protrusions 211 can be inserted into the positioning groove to achieve positioning and cooperation between the positioning groove and the positioning protrusions 211. This facilitates the positioning and cooperation between the first connecting shaft 221 and the impeller 210, ensures the assembly accuracy of the impeller 210 and the first connecting shaft 221, and helps to ensure the coaxiality between multiple impellers 210 and the first connecting shaft 221.

[0073] In some embodiments of the present invention, a second positioning part is provided at the end of the second connecting shaft 222 opposite to the wind turbine 210, and the second positioning part is used to position and cooperate with the wind turbine 210 arranged adjacent thereto. A third positioning part is provided at the end of the third connecting shaft 223 opposite to the wind turbine 210, and the third positioning part is used to position and cooperate with the wind turbine 210 arranged adjacent thereto.

[0074] The second and third positioning parts can both be constructed as positioning grooves so that the second and third positioning parts can be positioned and engaged with the positioning protrusions 211 on the wind turbine 210, so as to ensure the assembly accuracy of the wind turbine assembly 200 and help ensure the coaxiality of the wind turbine assembly 200.

[0075] It should be noted that the above positioning and matching method is only one embodiment of the present invention. The first connecting shaft 221, the second connecting shaft 222 and the third connecting shaft 223 can also be positioned and matched with the wind turbine 210 in other ways, as long as the coaxiality between the first connecting shaft 221, the second connecting shaft 222, the third connecting shaft 223 and the multiple wind turbines 210 is guaranteed. The specific positioning and matching method is not limited here.

[0076] In some embodiments of the present invention, the end of the first connecting shaft 221 is welded and fixed to the impeller 210. Specifically, the end of the first connecting shaft 221 can be fixed to the axial end face of the impeller 210 by ultrasonic welding to ensure the reliability of the connection between the first connecting shaft 221 and the impeller 210. Furthermore, there is no need to provide a connector for connecting the first connecting shaft 221 and the impeller 210, which helps to reduce the number of components in the wind turbine assembly 200 and reduce the production cost of the wind turbine assembly 200.

[0077] It should be noted that the specific method of fixing the first connecting shaft 221 and the impeller 210 can be determined according to the actual production and assembly requirements. No specific limitation is made here, as long as the first connecting shaft 221 and the impeller 210 are fixed in a non-detachable manner.

[0078] Combination Figure 1 and Figure 2In some embodiments of the present invention, flange structures are provided at both ends of the first connecting shaft 221 along the axial direction. The flange structures extend along the circumferential direction of the first connecting shaft 221 and are perpendicular to the axis of the first connecting shaft 221. The flange structures can increase the connection area between the first connecting shaft 221 and the impeller 210, which is beneficial to improving the connection reliability between the impeller 210 and the first connecting shaft 221.

[0079] Further reference Figure 1 A reinforcing rib 2212 is provided between the outer peripheral wall of the first connecting shaft 221 and the flange structure. The reinforcing rib 2212 connects the first connecting shaft 221 and the flange structure. The reinforcing rib 2212 is constructed in a triangular shape to support the flange structure and the outer peripheral wall of the first connecting shaft 221, thereby improving the structural strength between the flange structure and the first connecting shaft 221 and preventing the flange structure from folding or being damaged.

[0080] Furthermore, multiple reinforcing ribs 2212 are provided, and the multiple reinforcing ribs 2212 are evenly spaced in the circumferential direction of the first connecting shaft 221 to further improve the structural strength between the flange structure and the first connecting shaft 221.

[0081] In some embodiments of the present invention, the structure of the end of the second connecting shaft 222 and the third connecting shaft 223 near the impeller 210 can be the same as the structure of the end of the first connecting shaft 221. That is, the end of the second connecting shaft 222 and the third connecting shaft 223 near the impeller 210 is provided with a flange structure and a reinforcing structure, and the connection method between the second connecting shaft 222 and the third connecting shaft 223 and the impeller 210 can be the same as the connection method between the first connecting shaft 221 and the impeller 210, so as to facilitate the processing and assembly of the wind turbine assembly 200. These details will not be elaborated here.

[0082] The duct air conditioner 10 according to the present invention includes the above-described fan blade assembly 200.

[0083] Since the duct machine 10 is equipped with the aforementioned fan blade assembly 200, by directly connecting the first connecting shaft 221 to the impeller 210 located at both ends of its axial direction, the component arrangement of the fan blade assembly 200 is simplified, the production cost of the fan blade assembly 200 is effectively reduced, and the installation process of the fan blade assembly 200 is simplified, thereby improving the installation efficiency of the fan blade assembly 200.

[0084] The following reference Figures 5 to 7 A duct air conditioner 10 according to an embodiment of the present invention is described.

[0085] Combination Figure 5 and Figure 7In some embodiments of the present invention, the duct air conditioner 10 further includes a housing assembly 120, the fan blade assembly 200 is mounted on the housing assembly 120, and the housing assembly 120 includes: a first housing 121, the first housing 121 having a plurality of fan wheel mounting portions 1211 arranged sequentially along a first direction, each fan wheel mounting portion 1211 having an air outlet 1212; a plurality of second housings 122, the plurality of second housings 122 being respectively connected to the plurality of fan wheel mounting portions 1211 and forming mounting cavities respectively, each mounting cavity being able to accommodate a fan wheel 210.

[0086] It should be noted that "first direction" refers to the axial direction of wind turbine 210. A detailed directional diagram can be found in [reference needed]. Figure 5 As shown.

[0087] Specifically, multiple wind turbine mounting parts 1211 are formed on the first shell 121, that is, multiple wind turbine mounting parts 1211 are integrally formed with the first shell 121 to simplify the component arrangement of the shell assembly 120, thereby simplifying the assembly steps of the shell assembly 120 and improving the assembly efficiency of the shell assembly 120.

[0088] Furthermore, multiple wind turbine mounting portions 1211 are spaced apart in the first direction, and the shell assembly 120 also includes multiple second shells 122. The multiple second shells 122 are correspondingly arranged and connected to the multiple wind turbine mounting portions 1211. By separately setting the second shells 122, it is easier to install the wind turbine 210 in the wind turbine mounting portion 1211, thereby improving the assembly convenience of the wind turbine 210.

[0089] Furthermore, the second shell 122 and the impeller mounting part 1211 together define a mounting cavity for mounting the impeller 210. Each impeller mounting part 1211 has an air outlet 1212, which can drive airflow when the impeller 210 rotates in the mounting cavity.

[0090] In related technologies, the first shell and multiple wind turbine mounting parts are separately set up. Each wind turbine mounting part needs to be assembled onto the first shell through connectors, resulting in a large number of parts in the shell assembly and a large number of assembly processes, which reduces the assembly efficiency of the shell assembly.

[0091] This application simplifies the component arrangement of the shell assembly 120 by forming multiple wind turbine mounting portions 1211 on the first shell 121, thereby simplifying the assembly steps of the shell assembly 120, improving the assembly efficiency of the shell assembly 120, and helping to ensure the coaxiality of the multiple wind turbine mounting portions 1211, which in turn helps to ensure the coaxiality of the multiple wind turbines 210. In addition, by separately providing a second shell 122 to facilitate the installation of the wind turbines 210 into the wind turbine mounting portions 1211, the assembly efficiency of the shell assembly 120 is improved while the assembly convenience of the wind turbines 210 is also improved.

[0092] Combination Figure 5and Figure 6 In some embodiments of the present invention, the duct air conditioner 10 further includes a chassis 110, the chassis 110 having an air outlet frame 111, a first housing 121 mounted on the chassis 110 and disposed opposite to the air outlet frame 111, and airflow can flow to the air outlet frame 111 through the air outlet 1212.

[0093] Combination Figure 5 and Figure 6 In some embodiments of the present invention, the first housing 121 is further provided with a motor mounting part 1213, which is located on one side of the plurality of wind turbine mounting parts 1211 in the first direction and is used to mount the motor 300.

[0094] Specifically, the motor mounting part 1213 is formed at one end of the first housing 121 in the first direction, that is, the motor mounting part 1213, the first housing 121 and the multiple wind turbine mounting parts 1211 are integrally arranged to further simplify the component arrangement of the housing assembly 120 and simplify the processing steps of the housing assembly 120.

[0095] Furthermore, the motor mounting part 1213 and the wind turbine mounting part 1211 are arranged opposite to each other in the first direction. The motor mounting part 1213 is used to mount the motor 300. The motor 300 is connected to the transmission shaft section 2221 and is used to drive the multiple wind turbines 210 to rotate.

[0096] Combination Figures 5 to 7 In some embodiments of the present invention, the first housing 121 is further provided with a bearing seat mounting portion 1214, which is located on the other side of the plurality of wind turbine mounting portions 1211 in the first direction and is used to mount the bearing seat 1218.

[0097] Specifically, the bearing housing mounting portion 1214 is formed at one end of the first housing 121 away from the motor mounting portion 1213 in the first direction. That is, the bearing housing mounting portion 1214, the motor mounting portion 1213, the first housing 121 and the multiple impeller mounting portions 1211 can be integrally formed to further simplify the component arrangement of the housing assembly 120 and simplify the processing steps of the housing assembly 120.

[0098] Furthermore, the bearing housing mounting part 1214 and the impeller mounting part 1211 are arranged opposite to each other in the first direction. The bearing housing mounting part 1214 is used to install the bearing housing 1218. The support shaft 2231 can be rotatably mounted on the bearing housing 1218 through the bearing. The bearing housing 1218 can be used to support the bearing, which facilitates the rotation of the impeller 210 relative to the first housing 121 and can reduce the wear of the support shaft 2231.

[0099] The first shell 121 can be injection molded, and the motor mounting part 1213, the bearing seat mounting part 1214 and multiple impeller mounting parts 1211 can be formed on the first shell 121, realizing the integrated setting of multiple components, simplifying the components required for assembling the shell assembly 120, improving the assembly efficiency of the shell assembly 120, and the motor mounting part 1213 and the bearing seat mounting part 1214 are processed in the same production process to effectively ensure the coaxiality of the motor mounting part 1213 and the bearing seat mounting part 1214.

[0100] In some embodiments of the present invention, the motor 300 is coaxially arranged with the bearing.

[0101] Specifically, the motor mounting part 1213 and the bearing housing mounting part 1214 are coaxially arranged. By making the bearing housing mounting part 1214, the motor mounting part 1213, the first shell 121 and the multiple impeller mounting parts 1211 integrally formed, it is beneficial to ensure the coaxiality of the bearing housing mounting part 1214 and the motor mounting part 1213, so as to ensure the coaxiality of the motor 300 and the bearing housing 1218. This avoids the vibration of the machine body caused by the large coaxiality error between the motor 300 and the bearing housing 1218, thereby reducing the wear of the motor 300 and the bearing and improving the service life of the motor 300 and the bearing.

[0102] Reference Figure 5 In some embodiments of the present invention, the first shell 121 includes a base plate 1216 and a support beam 1217. The support beam 1217 is arranged perpendicular to the base plate 1216 and is arranged opposite to the air outlet frame 111. An air outlet 1212 is formed on the support beam 1217 and is arranged opposite to the air outlet frame 111. A part of the impeller mounting part 1211 is formed on the support beam 1217 and another part of the impeller mounting part 1211 is formed on the base plate 1216. The support beam 1217 can be supported at the position of the air outlet frame 111 to improve the rigidity of the shell assembly 120 and reduce the risk of deformation of the shell assembly 120.

[0103] like Figure 6 As shown, in some embodiments of the present invention, the shell assembly 120 further includes a partition 130, which is mounted on the chassis 110 and disposed between the air outlet frame 111 and the first shell 121, and the first shell 121 is connected to the partition 130.

[0104] Specifically, the partition 130 extends along the first direction and is arranged parallel to the support beam 1217. The partition 130 is mounted on the chassis 110 and located between the air outlet frame 111 and the support beam 1217. The partition 130 can further support the air outlet frame 111 to further improve the rigidity of the shell assembly 120 and reduce the risk of deformation of the shell assembly 120. For example, when the shell assembly 120 is longer in the first direction, the shell assembly 120 needs greater body rigidity to resist deformation. The rigidity of the shell assembly 120 can be improved by setting the partition 130, thereby reducing the risk of deformation of the shell assembly 120.

[0105] Furthermore, the first shell 121 is connected to the chassis 110 via a partition 130, and the first shell 121 has a motor mounting part 1213, a bearing housing mounting part 1214, and multiple impeller mounting parts 1211. That is, the motor mounting part 1213, the bearing housing mounting part 1214, and the multiple impeller mounting parts 1211 can be mounted on the chassis 110 via the partition 130, which ensures the rigidity of the shell assembly 120 while improving the assembly convenience of the shell assembly 120.

[0106] like Figure 6 As shown, in some embodiments of the present invention, the partition 130 is provided with a plurality of ventilation holes 131, and the plurality of ventilation holes 131 are respectively arranged opposite to a plurality of air outlets 1212.

[0107] Specifically, multiple ventilation holes 131 are arranged sequentially on the partition plate 130 along the first direction, and the multiple ventilation holes 131 are corresponding to multiple air outlets 1212. When the motor 300 drives the impeller 210 to rotate, the impeller 210 drives the airflow, and the airflow can flow from the air outlet 1212 into the ventilation holes 131.

[0108] In some embodiments of the present invention, the chassis 110 also forms an installation space, which is located on the side of the air outlet frame 111 away from the shell assembly 120 and is used to install a heat exchanger.

[0109] Specifically, the installation space is located on the side of the air outlet frame 111 away from the shell assembly 120. A heat exchanger is installed in the installation space, and the air outlet 1212 and the ventilation hole 131 are connected to the installation space. When the motor 300 drives the impeller 210 to rotate, the impeller 210 drives the airflow. The airflow can flow into the installation space through the air outlet 1212 and the ventilation hole 131, and the airflow can exchange heat with the heat exchanger. The installation space is also connected to the external environment (e.g., the indoor environment). The airflow after heat exchange can be transported from the shell assembly 120 to the external environment, thereby changing the temperature of the external environment.

[0110] Combination Figure 5 and Figure 6In some embodiments of the present invention, a plurality of impeller mounting portions 1211 are spaced apart in a first direction, and the impeller mounting portions 1211 and the second shell 122 form an axial air inlet 1215.

[0111] Specifically, the second shell 122 can be fastened and connected to the impeller mounting part 1211, and after the second shell 122 and the impeller mounting part 1211 are fastened and connected, an axial air inlet 1215 is formed between them along the first direction. The axial air inlet 1215 can be connected to the external environment. Airflow can enter the mounting cavity along the axial direction through the axial air inlet 1215, and further flow into the mounting space through the air outlet 1212 and the ventilation hole 131. The airflow can exchange heat with the heat exchanger in the mounting space.

[0112] Furthermore, multiple impeller mounting portions 1211 are spaced apart in the first direction so that two adjacent axial air inlets 1215 can be spaced apart to allow airflow to enter each mounting cavity. In addition, multiple second shells 122 are individually provided and connected to the multiple impeller mounting portions 1211 one by one to effectively prevent airflow from being obstructed from entering the mounting cavity due to the connection of multiple second shells 122, thus ensuring air intake efficiency.

[0113] like Figure 7 As shown, in some embodiments of the present invention, the duct unit 10 further includes a motor mounting mating part 400, which is mounted on the first housing 121. Specifically, the motor mounting mating part 400 is mounted to engage and connect with the motor mounting part 1213. The motor mounting mating part 400 and the motor mounting part 1213 together define a cavity. The motor 300 is mounted in the cavity and is connected to the drive shaft section 2221. The motor mounting mating part 400 and the motor mounting part 1213 can be used to protect the motor 300 and improve the service life of the motor 300.

[0114] In some embodiments of the present invention, the housing assembly 120 is provided with an air inlet and an air outlet for the ducted air conditioner. The air inlet is connected to the axial air inlet 1215, and airflow from the external environment can enter the housing assembly 120 through the air inlet and flow to the axial air inlet 1215.

[0115] The air outlet of the ducted air conditioner is connected to the installation space and is directly opposite the air outlet frame 111. The heat exchanger is located between the air outlet frame 111 and the heat exchanger of the ducted air conditioner 10. The fan wheel 210 rotates to drive the airflow from the air outlet 1212 into the installation space. After the airflow exchanges heat with the heat exchanger, it can be discharged from the ducted air conditioner 10 through the air outlet.
