The maintenance cost for users is high, and the connection structure of the fan is still relatively complex with low structural stability, requiring further improvements to the fan. Utility Model Content

[0005] The purpose of this utility model is to provide a duct fan structure that aims to solve at least one of the technical problems in the prior art.

[0006] To achieve the above objectives, the present invention provides a duct fan structure, comprising:

[0007] The base has mounting seats at both ends, and each mounting seat has a first annular groove.

[0008] Two connecting ports are provided, and a limiting step is provided on the opposite side of each of the two connecting ports. By at least partially embedding the limiting step into the first annular groove, the connecting ports are laterally limited and installed on the mounting base, and an installation space is formed between the two connecting ports.

[0009] A duct fan, wherein the duct fan is installed within the installation space;

[0010] The bottom of the limiting step is provided with a support platform structure to support the duct fan. Each mounting base is provided with a limiting component. One end of the limiting component is rotatably connected to one end of the mounting base, so that the other end of the limiting component can be closed with the other end of the mounting base to longitudinally position the duct fan and the connecting pipe.

[0011] Furthermore, the limiting step is a protruding annular wall formed by the radial outward extension of the end of the connecting pipe, and the two ends of the pipe fan are respectively connected to the two connecting pipes.

[0012] Furthermore, the support platform structure includes:

[0013] A structural plate, wherein the structural plate is formed by the outer peripheral edge of the bottom of the limiting step protruding outward along the axial direction of the duct fan, and an mounting surface is formed on the upper surface of the structural plate;

[0014] Multiple ribs are disposed on the mounting surface so that at least one of the ribs supports the duct fan when the duct fan is installed into the mounting space.

[0015] Furthermore, the outer contour of the structural plate is adapted to the contour of the inner wall of the first annular groove, so that when the limiting step is embedded in the first annular groove, the outer peripheral surface of the support platform structure abuts against the inner wall of the first annular groove.

[0016] Furthermore, multiple ribs are spaced apart on the mounting surface along a direction perpendicular to the axis of the duct fan.

[0017] Furthermore, the outer peripheral surface of the duct fan is arc-shaped, wherein the height of the plurality of ribs gradually decreases from left to middle and gradually increases from middle to right, so that the plurality of ribs can jointly contact and support the outer peripheral surface of the duct fan.

[0018] Furthermore, the inner circumferential surface of the limiting member is provided with a second annular groove, so that when the other end of the limiting member is closed with the other end of the mounting base, the limiting step is at least partially embedded in the second annular groove.

[0019] Furthermore, the outer peripheral surfaces of both ends of the duct fan are formed with connecting rings, and when the other end of the limiting member is closed with the other end of the mounting base, the connecting ring can be at least partially embedded in the second annular groove.

[0020] Furthermore, the duct fan includes:

[0021] A housing is disposed within the installation space, and a motor mount is disposed within the housing, with a receiving cavity formed on the motor mount;

[0022] A sound-absorbing duct, wherein the sound-absorbing duct is disposed at both ends inside the outer casing;

[0023] An electric motor is disposed within the accommodating cavity, and fan blades are provided on the output shaft of the motor.

[0024] Furthermore, the outer casing is provided with a receiving box to form a receiving cavity inside the receiving box, and a control component is provided inside the receiving cavity;

[0025] The outer surface of the housing has a wiring channel communicating with the accommodating cavity. The axis of the wiring channel is perpendicular to the axis of the duct fan. The control component is electrically connected to the motor through the wiring channel.

[0026] As can be seen from the above technical solution, the duct fan structure of this utility model, by setting mounting seats at both ends of the base, uses the mounting seats to respectively limit the installation of two connecting pipe ports to the two sides of the base, so as to form an installation space between the two connecting pipe ports. The installation space provides installation space for the duct fan. By setting a first annular groove on each of the two mounting seats and setting a limiting step on the opposite side of each of the two connecting pipe ports, the connecting pipe ports are installed on the base by embedding the limiting steps into the first annular grooves, and the connecting pipe ports are laterally limited. Supports are set on the limiting steps. The support structure ensures that the duct fan is supported when installed in the installation space, preventing accidental shaking after installation and improving its stability during operation. It also reduces the frequency of user maintenance. A limiting device on the mounting base allows the duct fan and connecting pipe to be longitudinally positioned on the base, ensuring strong fan stability and preventing accidental shaking. The simple and compact connection structure prevents loosening, ensuring stability, reliability, and easy assembly, resulting in better fan performance.

[0041] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] Please refer to the following: Figures 1 to 8 This embodiment provides a duct fan structure, the key features of which include a base 100, two connecting pipe ports 200, and a duct fan 300. Mounting seats 110 are respectively provided at both ends of the base 100. Each mounting seat 110 has a first annular groove 111. Limiting steps 210 are provided on opposite sides of the two connecting pipe ports 200. By at least partially embedding the limiting steps 210 into the first annular grooves 111, the connecting pipe ports 200 are laterally limited and mounted on the mounting seats 110. An installation space 230 is formed between the pipe ports 200. The duct fan 300 is installed in the installation space 230. A support platform structure 240 is provided at the bottom of the limiting step 210 to support the duct fan 300. Each mounting base 110 is provided with a limiting member 112. One end of the limiting member 112 is rotatably connected to one end of the mounting base 110 so that the other end of the limiting member 112 can be closed with the other end of the mounting base 110 to longitudinally position the duct fan 300 and the connecting pipe port 200.

[0043] As can be seen, the duct fan structure of this utility model, by setting mounting seats 110 at both ends of the base 100, uses the mounting seats 110 to respectively limit the installation of two connecting ports 200 to both sides of the base 100, so as to form an installation space 230 between the two connecting ports 200. The installation space 230 provides installation space 230 for the duct fan 300. By setting first annular grooves 111 on the two mounting seats 110 respectively and setting limiting steps 210 on the opposite side of the two connecting ports 200 respectively, the limiting steps 210 are embedded in the first annular grooves so that the connecting ports 200 are installed on the base 100 and the connecting ports 200 are laterally limited. A support platform structure 240 is set on the limiting step 210. When the duct fan 300 is installed into the installation space 230, it is supported by the support platform structure 240. This can prevent the duct fan 300 from shaking unexpectedly after installation, improve the stability of the duct fan 300 during operation, and reduce the frequency of user maintenance. By setting the limiting member 112 on the mounting base 110, the other end of the limiting member 112 is closed to the other end of the mounting base 110 so that the duct fan 300 and the connecting pipe 200 are longitudinally positioned on the mounting base 110. The fan is highly stable and not prone to unexpected shaking. Its connection structure is compact and not easy to loosen, so that the fan has a better working effect.

[0044] In this embodiment, the limiting step 210 is a protruding annular wall formed by the radially outward extension of the end of the connecting pipe 200, and the two ends of the duct fan 300 are respectively connected to the two connecting pipes 200.

[0045] By setting a first snap-fit ​​structure at the other end of the limiting member 112 and a corresponding second snap-fit ​​structure at the other end of the mounting base 110, the other end of the limiting member 112 and the other end of the mounting base 110 are closed and fixed by snapping the first snap-fit ​​structure onto the second snap-fit ​​structure. The first snap-fit ​​structure and the second snap-fit ​​structure are existing technologies and will not be described in detail here. In other embodiments, screw connection or adhesive connection structures can also be used.

[0046] Please refer to the following: Figures 1 to 8 The limiting step 210 is a protruding ring wall formed by the radial outward extension of the end of the connecting pipe 200. The connecting pipe 200 and the limiting step 210 are integrally formed structures. This setting simplifies the production process and reduces the complexity of the structure. The two ends of the duct fan 300 are respectively connected to the two connecting pipes 200. The two connecting pipes 200 are used to connect different pipes so that different pipes are respectively connected to the two ends of the duct fan 300.

[0047] Further, please refer to Figure 1 and Figure 2The support platform structure 240 includes a structural plate 241 and a plurality of ribs 242. The structural plate 241 is formed by the outer peripheral edge of the bottom of the limiting step 210 extending outward along the axial direction of the duct fan 300. An mounting surface 241a is formed on the upper surface of the structural plate 241. The plurality of ribs 242 are disposed on the mounting surface 241a so that when the duct fan 300 is installed into the mounting space 230, at least one rib 242 supports the duct fan 300.

[0048] Preferably, the support platform structure 240 and the limiting step 210 are integrally formed. This arrangement allows the duct fan 300 to be placed on the rib plate 242, which can stably support the duct fan 300 in the installation space 230 between the two connecting pipes 200, ensuring that the duct fan 300 will not shake or shift unexpectedly after installation, thus improving the overall stability of the fan.

[0049] Preferably, please refer to the following: Figures 1 to 8 The outer contour of the structural plate 241 is adapted to the inner contour of the first annular groove 111, so that when the limiting step 210 is embedded in the first annular groove 111, the outer peripheral surface of the support platform structure 240 abuts against the inner wall of the first annular groove 111. This arrangement of the support platform structure 240 can better transmit the pressure applied to it by the duct fan 300 to the base 100, so that the support platform structure 240 can stably support the duct fan 300 and effectively improve the stability of the duct fan 300.

[0050] Preferably, please refer to Figure 1 and Figure 2 Multiple ribs 242 are spaced apart on the mounting surface 241a along the direction perpendicular to the axis of the duct fan 300. The multiple ribs 242 can distribute the weight of the duct fan 300 to different positions, avoiding concentrated force on the limiting step 210 or the connecting pipe 200, thereby reducing the risk of structural damage and extending the service life of each component.

[0051] Preferably, please refer to Figure 1 and Figure 2The outer peripheral surface of the duct fan 300 is arc-shaped, with the height of multiple ribs 242 gradually decreasing from left to middle and gradually increasing from middle to right. This allows multiple ribs 242 to contact and support the outer peripheral surface of the duct fan 300. When the duct fan is placed on the ribs 242 of the support platform structure 240, the stress conditions at different positions are different. This arrangement can better fit the outer contour of the duct fan 300, making the contact between the duct fan 300 and the ribs 242 more reasonable. Multiple ribs 242 can provide support force to the duct fan 300 from different positions, distributing the weight of the duct fan 300 and avoiding stress concentration. This ensures the stability of the duct fan 300 within the installation space 230, making it less prone to shaking or displacement during operation.

[0052] Further, please refer to Figure 1 and Figure 2 The inner circumferential surface of the limiting member 112 is provided with a second annular groove 112a, so that when the other end of the limiting member 112 is closed with the other end of the mounting base 110, the limiting step 210 is at least partially embedded in the second annular groove 112a.

[0053] By embedding the limiting step 210 into the second annular groove 112a, the connecting pipe 200 can be accurately positioned and limited in the lateral direction, preventing the connecting pipe 200 from shifting or shaking in the lateral direction during operation, making the connection between the connecting pipe 200 and the mounting base 110 more stable and reliable, and ensuring the stability of the entire pipeline fan structure.

[0054] Furthermore, please refer to the following: Figures 1 to 8 The outer peripheral surfaces of both ends of the duct fan 300 are formed with connecting rings 310. When the other end of the limiting member 112 is closed with the other end of the mounting base 110, the connecting ring 310 can be at least partially embedded in the second annular groove 112a.

[0055] When the other end of the limiting member 112 is closed with the other end of the mounting base 110, the connecting rings 310 on the outer peripheral surfaces of both ends of the duct fan 300 can be at least partially embedded in the second annular groove 112a on the inner peripheral surface of the limiting member 112. This allows the duct fan 300 to be more accurately positioned in both the longitudinal and transverse directions, preventing longitudinal and transverse displacement during operation, ensuring the stability and reliability of the duct fan 300, enabling the duct fan structure to withstand greater external forces and stresses during operation, and making it less prone to component loosening or falling off, thus enhancing the overall structural stability of the duct fan.

[0056] Furthermore, please refer to the following: Figures 1 to 8The duct fan 300 includes a housing 320, a silencer duct 330, and a motor 340. The housing 320 is disposed within the installation space 230. A motor base 321 is disposed within the housing 320. A receiving cavity 322 is formed on the motor base 321. The silencer duct 330 is disposed at both ends within the housing 320. The motor 340 is disposed within the receiving cavity 322. A fan blade 350 is disposed on the output shaft of the motor 340.

[0057] The sound-absorbing duct 330 is installed at both ends inside the outer casing 320. The sound-absorbing duct 330 is provided with multiple sound-absorbing holes 331, which can effectively reduce the noise generated during the operation of the fan and improve the comfort of the user environment. The sound-absorbing duct 330 can absorb and block the airflow noise generated during the operation of the fan, and reduce the spread of noise to the surrounding environment.

[0058] Furthermore, such as Figure 8 As shown, a receiving box is provided on the outer casing 320 to form a receiving cavity 322 inside the receiving box. A control component 360 is provided inside the receiving cavity 322. A wire passage 323 communicating with the receiving cavity 322 is opened on the outer surface of the outer casing 320. The axis of the wire passage 323 is perpendicular to the axis of the duct fan 300. The control component 360 is electrically connected to the motor 340 through the wire passage 323.

[0059] By creating a wiring channel 323 on the outer casing 320 that connects to the accommodating cavity 322, and placing the control component 360 inside the accommodating cavity 322, a reasonable wiring channel is provided for the wires of components such as the motor 340. This allows for a smooth electrical connection between the motor 340 and the control component 360, thereby enabling control of the motor 340 and ensuring the normal operation of the fan. The control component 360 is used to drive the motor 340, and its specific structure is existing technology and will not be described in detail here.

[0060] In this embodiment, the structure of the wire passage 323 is reasonable by setting it in the middle of the outer surface of the housing 320. When it is necessary to increase the airflow or reverse the airflow, two accommodating cavities 322 are set on the motor base 321 to accommodate two motors 340 and fan blades 350 to achieve the corresponding effect.

[0061] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: By providing mounting seats 110 at both ends of the base 100, the mounting seats 110 are used to limit the installation of the two connecting pipe ports 200 to both sides of the base 100, so as to form an installation space 230 between the two connecting pipe ports 200. The installation space 230 provides an installation space 230 for the duct fan 300. By providing first annular grooves 111 on the two mounting seats 110 respectively and setting limiting steps 210 on the opposite side of the two connecting pipe ports 200 respectively, the limiting steps 210 are embedded in the first annular grooves so that the connecting pipe ports 200 are installed on the base 100, and the connecting pipe ports... The duct fan 300 is laterally limited, and a support platform structure 240 is set on the limiting step 210. When the duct fan 300 is installed into the installation space 230, it is supported by the support platform structure 240. This can prevent the duct fan 300 from shaking unexpectedly after installation, improve the stability of the duct fan 300 during operation, and reduce the frequency of user maintenance. By using the limiting member 112 set on the mounting base 110, the other end of the limiting member 112 is closed to the other end of the mounting base 110 so that the duct fan 300 and the connecting pipe 200 are longitudinally positioned on the mounting base 110. The fan is highly stable and not prone to unexpected shaking. Its connection structure is compact and not easy to loosen, so that the fan has a better working effect.
