[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1-7 As shown:

[0033] Example 1:

[0034] The fan body includes a housing 2 and a motor 4. The housing 2 has a hollow through slot inside, and a support 20 is provided on one side of the through slot. The support 20 is a protruding structure. The motor 4 has a base 40 on one side. The base 40 has a sliding groove inside, and the sliding groove and the support 20 are through-connected. One end of the motor 4 has a protruding drive shaft 5, which passes through the interior of the first fan 6 and the second fan 60. Its structural design is simple and reasonable, with a double-layer exhaust structure. The first fan 6 and the second fan 60 are driven by the same drive shaft 5, realizing energy saving of double-layer exhaust.

[0035] The first fan 6 has multiple ventilation holes 62 on one side and multiple first fan blades 7 on the outer periphery of the first fan 6. The first fan blades 7 are fixed on the top of the ventilation holes 62 and are in a shape that rotates around the motor 4. When the first fan blades 7 rotate, they can help to dissipate heat from the outside of the motor 4 and also guide and discharge air through the ventilation holes 62 and the channel.

[0036] The second fan 60 is surrounded by multiple second fan blades 70. The top of the second fan blades 70 and the bottom of the ventilation hole 62 are adjacent to each other. However, the fan body of this application realizes a double-layer exhaust structure. The first fan 6 is a single-layer exhaust structure to expand the exhaust range. The second fan 60 is located in the middle of the first fan 6, but it is a structure that concentrates the exhaust in the middle, forming a double-layer exhaust structure.

[0037] A protruding key block 61 is provided on one side of the drive shaft 5. The drive shaft 5 has a keyway in the hole through which the first fan 6 and the second fan 60 pass, which helps the drive shaft 5 to form a snap-fit ​​connection with the first fan 6 and the second fan 60. However, the first fan 6 and the second fan 60 form a structure driven by the same drive shaft 5, realizing energy saving of double-layer exhaust.

[0038] The outer shell 2 is provided with multiple reinforcing ribs 22 around its perimeter, and each reinforcing rib 22 has a hole on one side. One end of the outer shell 2 is provided with a first mesh 3, and the other end is provided with a second mesh 30. Each of the first mesh 3 and the second mesh 30 has a hole on one side. The holes provided by the reinforcing ribs 22 and the holes provided by the first mesh 3 and the second mesh 30 are locked with bolts, which facilitates the improvement of the stability of the installation of the first mesh 3 and the second mesh 30.

[0039] Example 2:

[0040] On the other side of the first fan 6, there is a limiting ring 63. The limiting ring 63 is a protruding structure. The limiting ring 63 passes through a groove provided at one end of the motor 4. The groove is located on the top surface of one end of the motor 4, and the groove and the drive shaft 6 are on the same end.

[0041] Example 3:

[0042] The first mesh 3 has a limiting block 300 in the middle, and a positioning hole 301 is provided on one side of the limiting block 300. One end of the drive shaft 5 passes through the positioning hole 301. The first mesh 6 and the second mesh 60 form a structure in which the motor 4 and the first mesh 3 are clamped, which helps to improve the stability of the rotation of the first mesh 6 and the second mesh 60.

[0043] Example 4:

[0044] A support base 21 is provided on one side of the outer casing 2. The support base 21 is a protruding structure, which facilitates the stable placement of the fan body.

[0045] Example 5:

[0046] The support 20 is L-shaped, and the first fan blade 7 rotates around the support 20 when it rotates.

[0047] Example 6:

[0048] The second blade 70 and the first mesh 3 are opposite to each other, but the first blade 6 and the second blade 60 form a structure that discharges in the direction of the first mesh 3.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
