[0028] In Embodiment 1 of the present utility model,

[0029] As Figure 1 shown in to, the present utility model provides a fixed support structure for a double-layer fan, including a fan body 1. The fan body 1 includes a first fan group 2 and a second fan group 3 arranged in an upper and lower stacked manner. The first fan group 2 is arranged at the upper end of the second fan group 3 through a fixed bracket unit 4. A control unit 5 is arranged in the fixed bracket unit 4. The fixed bracket unit 4 includes an annular fixed bracket 6, a water receiving tray 7 arranged in the annular fixed bracket 6, and a positioning fixed bracket 8 arranged at the upper end of the annular fixed bracket 6. The annular fixed bracket 6 is fixedly connected to the second fan group 3. The first fan group 2 is detachably arranged on the annular fixed bracket 6 through the positioning fixed bracket 8.

[0030] By setting the fixed support unit 4, the first fan group 2 is detachably arranged on the annular fixed frame 6 through the positioning fixed frame 8, which facilitates the assembly and disassembly of the double-layer fan. When it is necessary to repair or replace the first fan group 2, only the corresponding fixed connection needs to be released, and the operation is simple and fast, saving time and labor.

[0031] The positioning fixed frame 8 includes an outer ring fixed frame 9 and an inner ring positioning piece 13. The inner ring positioning piece 13 is arranged at intervals inside the outer ring fixed frame 9. The first fixing holes 11 are arranged at any position of the outer ring fixed frame 9. The first fan group 2 is clamped between the outer ring fixed frame 9 and the inner ring positioning piece 13 and is detachably connected through the first fixing holes 11 and arranged at the upper end of the positioning fixed frame 8.

[0032] Through the cooperation of the outer ring fixed frame 9 and the inner ring positioning piece 13 of the positioning fixed frame 8, the first fan group 2 can be accurately fixed, ensuring the accuracy and stability of its installation position. At the same time, through the first fixing holes 11, detachable connection is realized, which facilitates the separate disassembly, installation and maintenance of the first fan group 2.

[0033] At least one or more fixing columns 12 and positioning pieces 13 are arranged along the inner side of the annular fixed frame 6. The positioning pieces 13 and the fixing columns 12 are integrally or separately arranged on the inner side of the annular fixed frame 6. The second fixing holes 14 are arranged on the outer surface of the annular fixed frame 6. The third fixing holes 15 corresponding to the fixing columns 12 are arranged inside the second fan group 3. The annular fixed frame 6 sleeves the upper end of the second fan group 3 through the positioning pieces 13 and is fixedly connected through the fixing columns 12 and the third fixing holes 15, and the annular fixed frame 6 is fixedly arranged at the upper end of the second fan group 3 through the second fixing holes 14.

[0034] The design of the fixing columns 12, the positioning pieces 13 on the inner side of the annular fixed frame 6 and the second fixing holes 14 on the outer surface makes the connection between the annular fixed frame 6 and the second fan group 3 firm and reliable. The positioning pieces 13 can accurately sleeve and position. The cooperation of the fixing columns 12 and the third fixing holes 15 and the fixing of the second fixing holes 14 ensure the stability of the overall structure of the double-layer fan.

[0035] The control unit 5 includes a control panel 16 and a control box 17. The control panel 16 penetrates the outer surface of the annular fixed frame 6, and the control box 17 is arranged inside the annular fixed frame 6 and connected to the control panel 16.

[0036] By penetrating the control panel 16 through the outer surface of the annular fixed frame 6 and arranging the control box 17 inside the annular fixed frame 6, convenient control of the double-layer fan is realized. At the same time, this layout saves space and makes the structure more compact.

[0037] A boss 18 is provided at the inner bottom of the water receiving tray 7, and water distribution holes 19 and water guiding grooves 20 are arranged at any position along the edge of the boss 18.

[0038] Through the design of the water receiving tray 7, the water droplets generated during the operation of the fan can be collected. The boss 18, the water diversion holes 19 and the water guiding grooves 20 at the bottom can effectively guide the water flow, avoid water accumulation, and keep the environment around the fan dry.

[0039] The annular fixing frame 6 and the water receiving tray 7 are integrally formed.

[0040] Through the integral formation of the annular fixing frame 6 and the water receiving tray 7, not only the number of components is reduced, the production process is simplified, and the cost is lowered, but also the strength and stability of the overall structure are enhanced.

[0041] As Figure 1 As shown in the figure, the first fan group 2 is detachably arranged on the annular fixing frame 6 through the positioning fixing frame 8. The cooperation between the outer ring fixing frame 9 and the inner ring positioning piece 13 enables the first fan group 2 to be accurately and stably installed, and convenient disassembly, assembly and maintenance are realized through the first fixing holes 11. The fixing columns 12 on the inner side of the annular fixing frame 6, the positioning pieces 13 and the second fixing holes 14 on the outer surface can be firmly connected with the second fan group 3 to ensure the stability of the overall structure. The control panel 16 of the control unit 5 penetrates through the outer surface of the annular fixing frame 6, and the control box 17 is located inside, which is convenient for control and saves space. The boss 18, the water diversion holes 19 and the water guiding grooves 20 at the inner bottom of the water receiving tray 7 can effectively handle the water droplets and avoid water accumulation. The annular fixing frame 6 and the water receiving tray 7 are integrally formed, reducing the number of components, simplifying the process, lowering the cost, and enhancing the structural strength and stability.

[0042] In Embodiment 2,

[0043] As Figure 1 As shown in the figure, when the power is turned on, the first fan group 2 and the second fan group 3 are started simultaneously. The airflows generated by the first fan group 2 and the second fan group 3 interact with each other to jointly provide stronger wind power and a wider air supply range for the user. During the operation, the fixed support unit 4 plays a key supporting and fixing role. The annular fixing frame 6 firmly fixes the second fan group 3, and the fixing columns 12 and the positioning pieces 13 on the inner side ensure the accuracy and stability of the connection. The outer ring fixing frame 9 and the inner ring positioning piece 13 of the positioning fixing frame 8 accurately fix the first fan group 2 to ensure its stable operation. The control unit 5 is used to control functions such as the rotation speed and the wind speed mode of the fan. The user sends instructions to the control box 17 by operating the control panel 16, thereby realizing various adjustments of the fan. The water receiving tray 7 is used to collect the water droplets generated during the operation of the fan. After the water droplets fall into the water receiving tray 7, under the action of the boss 18, they flow to the water diversion holes 19 and the water guiding grooves 20 at the edge and are orderly guided out to keep the environment around the fan dry.

[0044] In Embodiment 3,

[0045] As Figure 1 shown in to , when assembly is required, first sleevethe annular fixing bracket 6 on the upper end of the second fan group 3 through the positioning piece 13 on its inner side, align the fixing column 12 with the corresponding third fixing hole 15 in the second fan group 3, and then fix it through a connecting piece. Next, snap the first fan group 2 between the outer fixing bracket 9 and the inner positioning piece 13 of the positioning fixing bracket 8, and fix it to the upper end of the positioning fixing bracket 8 through the first fixing hole 11 using a connecting piece to complete the assembly of the double-layer fan. When disassembly is required, just loosen the screws and other connecting pieces at the first fixing hole 11 and the fixing column 12, and the first fan group 2 and the annular fixing bracket 6 can be removed from the positioning fixing bracket 8 and the second fan group 3 respectively. This detachable design enables each part to be separated conveniently and quickly when the fan needs maintenance, cleaning or component replacement, greatly improving the operation convenience and efficiency.
