[0023] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] As mentioned above, the existing technology is a linear air supply duct fan, the shell thickness is much larger than the duct thickness, resulting in the problem of occupying too much space, and generally only has one air inlet, which cannot meet the requirements of occupying less space and having more air inlets. Therefore, there is an urgent need for a multi-inlet ultra-thin duct fan, which uses an extremely thin shell to greatly reduce the overall thickness and improve space utilization; at the same time, a single duct fan has multiple air inlets, and without increasing the number of duct fans, multiple air inlet ducts can be connected to achieve the effect of multi-directional air intake.

[0025] The application of the multi-inlet ultra-thin duct fan provided by the present invention in high-rise buildings will be introduced below.

[0026] Please refer to Figure 1 and Figure 7 A multi-inlet ultra-thin duct fan comprises: an extremely thin shell, one end of which is provided with an air outlet, and the other end of which is provided with multiple air inlets, wherein at least two air inlets are located on the left and right sides of the extremely thin shell; the air inlets are equipped with detachable blocking gaskets; a motor bracket, which is mounted on the extremely thin shell by screws, and the motor bracket is provided with a non-disassembly screw structure; so that the motor bracket can be disassembled and assembled on the extremely thin shell without removing the screws; and an installation bracket, which is rotatably installed on both sides of the extremely thin shell for storage in a non-installed state.

[0027] Exemplarily, the extremely thin shell is formed by fixing an upper shell and a lower shell.

[0028] Exemplarily, the disassembly-free screw structure includes an arc-shaped narrow groove opened on the motor bracket, the number of the arc-shaped narrow grooves is several, and the arc-shaped narrow grooves are distributed in a ring array, and an entrance hole is provided at one end of the arc-shaped narrow groove.

[0029] Exemplarily, the screw is threadedly connected to a screw hole provided on the extremely thin shell, and the screw passes through the arc-shaped narrow groove.

[0030] Exemplarily, the width of the arc-shaped narrow groove is smaller than the diameter of the head of the screw, and the diameter of the access hole is larger than the diameter of the head of the screw.

[0031] Exemplarily, a pin is provided in the middle of the mounting bracket, and the mounting bracket is rotatably connected to the extremely thin shell through the pin.

[0032] In some embodiments, the multi-inlet ultra-thin duct fan of the present disclosure further includes an impeller assembly; the impeller assembly is mounted on a motor bracket.

[0033] Specifically, Figure 1 and Figure 7As shown, the multi-inlet ultra-thin duct fan described in this scheme includes an upper shell 1, a lower shell 2, an air inlet 3, a mounting bracket 4, a pin 401, an air outlet 5, a motor bracket 6, an impeller assembly 7, a screw 8, a sealing gasket 9, an arc-shaped narrow groove 10, and an inlet and outlet hole 11.

[0034] The upper shell 1 and the lower shell 2 are riveted together by cold riveting equipment to form an extremely thin shell, and an air outlet 5 is formed at one end of the extremely thin shell, and multiple air inlets 3 are formed at the other end; the middle part of the mounting bracket 4 is installed on the extremely thin shell through a pin 401, and the mounting bracket 4 and the pin 401 are rotatable, and then the impeller assembly 7 is installed on the motor bracket 6, and the motor bracket 6 is fixed to the extremely thin shell with a screw 8.

[0035] like Figure 7 As shown, the thickness of the multi-inlet ultra-thin duct fan disclosed in the present invention is only 25 mm thicker than the air inlet 3 and the air outlet 5 connected to the duct, and the thickness of the air inlet 3 and the air outlet 5 is the same as that of the duct; thus, the extremely thin shell of the multi-inlet ultra-thin duct fan is much smaller than the shell of the traditional linear air supply duct fan.

[0036] Usage and steps:

[0037] 1) In the non-installed state, the mounting bracket 4 is stored in the extremely thin shell, and the mounting bracket 4 is completely in contact with the extremely thin shell without being exposed to prevent collision with foreign objects;

[0038] 2) Install the blocking gasket 9 to the air inlet 3 according to the on-site requirements to block the air inlet 3 that is not in use;

[0039] 3) By rotating the mounting bracket 4, the mounting bracket 4 is turned over and unfolded, and extends out from one side of the extremely thin shell, such as Figure 4 As shown, to provide a mounting position, the mounting bracket 4 is fixed to the high-rise building by bolts;

[0040] 4) When the impeller assembly 7 needs maintenance, loosen the screw 8, then rotate the motor bracket 6 to align the screw 8 with the access hole 11, and then pull the motor bracket 6 to quickly remove the motor bracket 6 assembly. To install the motor bracket 6 assembly, rotate it in the opposite direction. The screw 8 is located at one end of the arc-shaped narrow groove 10 away from the access hole 11. Then tighten the screw 8 to fix the motor bracket 6.

[0041] In the prior art, the shell thickness of the fan is much larger than the pipe thickness, resulting in the problem of occupying too much space, and generally only has one air inlet, which cannot meet the requirements of occupying less space and having more air inlets. Compared with the prior art, this technical solution uses a specific multi-inlet ultra-thin duct fan and an extremely thin shell to greatly reduce the overall thickness, thereby saving space and improving space utilization; at the same time, a single duct fan has multiple air inlets, which can be connected to multiple air inlet ducts without increasing the number of duct fans, and further, multiple air inlets are located in different directions to achieve the effect of multi-directional air intake; and by providing a non-disassembly screw structure on the motor bracket, the motor bracket does not need to be removed during the disassembly and assembly process on the extremely thin shell, which facilitates the maintenance of the motor bracket and the structure on the motor bracket. At the same time, the mounting bracket adopts a rotatable design, and is stored in the extremely thin shell when not installed to prevent bumps. When installing, it is unfolded and extended for installation.
