[0019] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] In the description of this application, it should be noted that for directional words, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, the directions and positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of this application.

[0021] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0022] One of the preferred embodiments of this application is as follows: Figures 1 to 5 The fan is connected to the fan wheel 4 by a shaft 6 and a gear 7. The fan is connected to the fan wheel 4 by a shaft 6. The fan is connected to the fan wheel 4 by a shaft 6.

[0023] The present application provides an assembled fan with independent fan units. Specifically, when in use, since the volute main body 1, the fan impeller 4, the balancing bracket 5 and the fan shaft 6 constitute an independent fan unit, when a strong fan air volume is needed, it is only necessary to connect the fan shafts 6 on the two independent fan units through the flexible coupling 7. Thereafter, the top end of the fan shaft 6 on the topmost fan unit is connected to the drive motor to complete the series operation between the two fan units. Thus, starting the drive motor can make the fan shafts 6 on each fan unit in series rotate. When the fan shaft 6 rotates, its bottom will drive the fan impeller 4 to rotate inside the volute main body 1, thereby achieving a large air volume discharge effect.

[0024] When the fan units are connected, the two fan units can be quickly controlled on a horizontal line with the assistance of the auxiliary mechanism. Thus, they can be quickly connected through the flexible coupling 7. The whole process does not require a lot of time for alignment, and the operation is fast and efficient.

[0025] As a further preferred basis of this embodiment Figure 1 and Figure 4 As shown, the auxiliary mechanism includes a fixed shell 2 and a positioning mechanism 3. The positioning mechanism 3 is provided in the internal hollow structure of the fixed shell 2. The two sides of the fixed shell 2 are connected to the outer wall of the volute body 1 in an arc-shaped structure, and the volute body 1 and the fixed shell 2 are fixed by bolts.

[0026] Preferably, the alignment mechanism 3 includes a pushing handle 31, an alignment plate 32 and an extrusion plate 33. The alignment plate 32 is arranged in a hollow structure inside the fixed shell 2, and the top of the alignment plate 32 is integrally installed with the pushing handle 31, and the pushing handle 31 passes through the through groove at the top of the fixed shell 2.

[0027] Preferably, the top of both sides are provided with an alignment plate 32, and the alignment plate 32 is arranged in an inclined shape, and the alignment plate 32 is made of metal;

[0028] Specifically, when positioning, the staff needs to pull the pushing handle 31 on the alignment mechanism 3 to make it slide in the through groove at the top of the fixed shell 2, thereby controlling the alignment plate 32 at the bottom thereof to slide, so that one side of the alignment plate 32 slides out of the internal hollow structure of the fixed shell 2. At this time, the slid-out alignment plate 32 is engaged with the inside of the fixed shell 2 on the adjacent fan unit. Since the entire auxiliary mechanism is provided at the upper and lower positions of the volute body 1 of the fan unit, when the upper and lower positions of the adjacent fan units are engaged through the alignment plates 32, the alignment work is completed.

[0029] Since an extrusion plate 33 is also provided on the outside of the alignment plate 32, the extrusion plate 33 can be reset when the alignment plate 32 enters the interior of the fixed shell 2 on the adjacent fan unit, thereby ensuring that the alignment plate 32 can be tightly engaged with the hollow structure inside the fixed shell 2, ensuring that there will be no loosening or displacement when the flexible coupling 7 is subsequently installed.

[0030] As a further preferred embodiment of the present invention, according to Figure 5 As shown, a damping rubber 8 is further provided between the balancing bracket 5 and the bearing 9 . The inside of the damping rubber 8 is engaged with the bearing 9 , and the outside of the damping rubber 8 is engaged with the balancing bracket 5 .

[0031] The balancing bracket 5 includes a fixing ring 51, a connecting rod 52, and a mounting sleeve 53. The middle of the fixing ring 51 is engaged with the damping rubber 8, and three connecting rods 52 are distributed at equal angles on the outside of the fixing ring 51. The top of the connecting rod 52 is integrally mounted with a mounting sleeve 53 with a hollow structure. The mounting sleeve 53 is used to connect and fix with the volute body 1 by a bolt engaged in the middle.

[0032] Specifically, the exterior of the bearing 9 is covered with high-quality damping rubber 8, which can eliminate the noise generated by vibration and ensure that the entire fan unit is quieter when working.

[0033] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments.
