[0030] As shown in Figure 1 and Figure 2 The utility model discloses a pipeline fan, including installation base 1 and motor 2, installation base 1 includes the cylindrical shell 11 and is located in the cylindrical shell 11 and the suspension support 12 of the empty space, the suspension support 12 is equipped with the installation hole 1221 of the bottom embedding of motor 2 can, when installing, the bottom embedding installation hole 1221 of motor 2 is fixed after.

[0031] The bottom of the motor 2 can be installed by embedding through the installation hole 1221, which greatly improves the stability of the motor 2 installation. Because the bottom of the motor 2 can not be blocked by the installation base 1, the motor 2 has sufficient heat dissipation area. In actual application, the heat generated by the operation of the motor 2 can be taken away by the air flow of the duct fan itself, so that the motor 2 can operate safely and efficiently at low temperature, effectively increasing the service life of the motor 2. In addition, the embedded installation reduces the center of gravity of the fan, thereby reducing the centrifugal force when the fan rotates, and improving the basic balance value, greatly reducing the number of efficiency balance.

[0032] In an embodiment, as shown in Figure 1 The installation hole 1221 is provided with a connecting hole 1222 for fixing the motor 2.

[0033] Specifically, the number of connecting holes 1222 is usually even, commonly 4 or 6, to ensure that the stress in each direction is uniform when the motor 2 is fixed.

[0034] In an embodiment, as shown in Figure 1 The overhanging support 12 includes an overhanging plate 122, and the overhanging plate 122 is provided with an installation hole 1221 penetrating in the thickness direction thereof.

[0035] The installation hole 1221 penetrating in the thickness direction of the overhanging plate 122 is the core part of the motor 2 installation. The shape of the installation hole 1221 is adapted to the shape of the bottom of the motor 2, which is generally circular or square. When the bottom of the motor 2 is circular, the diameter of the installation hole 1221 is slightly larger than the diameter of the bottom of the motor 2.

[0036] In an embodiment, the overhanging support 12 further includes a connecting piece 121 extending from the inner side of the cylindrical shell 11 to the center thereof, and the end of the connecting piece 121 is fixedly connected with the overhanging plate 122.

[0037] The connecting piece 121 extends from the inner side of the cylindrical shell 11 to the center thereof, and the main purpose is to stably connect the overhanging plate 122 with the cylindrical shell 11, and provide reliable support for the overhanging plate 122 and the motor 2 installed thereon.

[0038] The material of the connecting piece 121 is usually consistent with that of the cylindrical shell 11 and the overhanging plate 122, for example, also adopting plastic material. The thickness of the connecting piece 121 needs to ensure that it has sufficient strength to withstand various forces generated during the operation of the motor 2.

[0039] The shape of the connecting pieces 121 is various, and the common ones are straight strip or arc structure. The arc connecting piece 121 can better fit the inner surface of the cylindrical shell 11, and reduce the stress concentration phenomenon while uniformly transmitting the force. The number of the connecting pieces 121 is generally determined according to the size of the fan and the required support strength, and is usually 36. These connecting pieces 121 are uniformly and circularly spaced along the inner side of the cylindrical shell 11, and the interval area between the adjacent two connecting pieces 121 constitutes an air duct, which not only facilitates the air circulation, but also reduces the overall structure weight.

[0040] The end of the connecting piece 121 and the overhanging plate 122 can be fixed and connected by one-piece forming, welding, bonding or clamping.

[0041] In an embodiment, the lengths of the plurality of connecting pieces 121 are the same, so that the center of the mounting hole 1221 is the same as the center of the cylindrical shell 11. In this way, when the motor 2 is installed in the mounting hole 1221 of the overhanging plate 122, the center of the motor 2 is consistent with the center of the cylindrical shell 11, and the rotation of the motor 2 is more stable when the fan is running, which effectively reduces the vibration and noise caused by eccentricity. In addition, the center coincidence makes the airflow flow more uniformly and smoothly in the fan, improving the ventilation efficiency of the fan.

[0042] In an embodiment, the motor 2 is provided with a fixed part 21 near the bottom thereof, and the fixed part 21 is provided with a fixed hole 211 corresponding to the connecting hole 1222.

[0043] The fixed hole 211 provided on the edge of the fixed part 21 corresponds to the connecting hole 1222 around the mounting hole 1221 of the overhanging support 12, and is used to realize the connection and fixation of the motor 2 and the overhanging support 12. The number of the fixed hole 211 is consistent with that of the connecting hole 1222, and the positions are accurately matched so that the bolt can smoothly pass through.

[0044] In the actual installation process, after the motor 2 is embedded in the mounting hole 1221 of the overhanging support 12, the bolt is passed through the connecting hole 1222 and then screwed into the fixed hole 211, and the bolt is tightened by using a wrench or the like, so that the motor 2 and the overhanging support 12 are tightly fixed together. This fixing method is simple to operate and firmly and reliably connected.

[0045] In an embodiment, as shown in Figure 2 The fixed part 21 is in a ring structure, and the diameter of the fixed part 21 is greater than that of the mounting hole 1221.

[0046] The fixed part 21 adopts a ring structure, which can uniformly surround the bottom of the motor 2 and provide all-around support and fixation for the motor 2. The rationality of this structure design lies in that it can uniformly disperse the force generated by the motor 2 during operation, avoiding the case that the local force is too large.

[0047] The diameter of the fixing part 21 is larger than the diameter of the mounting hole 1221, and thus the fixing part 21 with a relatively larger diameter provides a wider area for arranging the fixing hole 211 to be connected and fixed with the connecting hole 1222 on the suspension support 12. Meanwhile, the fixing part 21 with a relatively larger diameter can limit the embedding degree of the bottom of the motor 2, so as to avoid excessive embedding from affecting the assembly.

[0048] In an embodiment, as shown in Figure 1 The side wall of the cylindrical shell 11 is provided with a plurality of ventilation holes 111. The number, size and distribution of the ventilation holes 111 can be determined according to actual conditions, and the shape of the ventilation holes 111 can be circular, square or oval.

[0049] The design of the ventilation holes 111 can significantly enhance the air circulation between the inside and outside of the fan. When the fan is running, the heat generated inside can be quickly dissipated to the outside through the ventilation holes 111, effectively reducing the internal temperature of the fan.

[0050] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
