As shown in fig. 1 to 6, the present invention provides a blower generating a spiral wind, including:
the fan blade comprises a fan blade shell 2, fan blades 3, a driving shaft 4, a coupling 5, a driving motor 6 and a fan blade shell bracket 8;
the blade surface of the fan blade 3 is arc-shaped, and is fixed on the inner side of the fan blade shell 2 along the circumferential direction of the fan blade shell 2 and at an included angle with the axial direction of the fan blade shell 2;
one end of the coupler 5 is connected with the driving shaft 4, and the other end of the coupler is connected with the driving motor 6;
the fan blade shell support 8 is symmetrically distributed at the front end and the rear end of the fan blade shell 2, one end of the fan blade shell support 8 is connected with the driving shaft 4, and the other end of the fan blade shell support is connected with the fan blade shell 2.
The driving motor 4 can convert the electric energy into mechanical energy, and the power is transmitted to the fan through a shaft of a driving motor 4 body; the shaft coupling 5 transmits the shaft power of the driving motor 4 to the fan blade shell support 6, drives the fan blade shell 2 to rotate through the fan blade shell support 6, and simultaneously drives the fan blades fixed on the fan blade shell 2 to rotate; the blade surface of the fan blade 3 is arc-shaped and connected with the fan blade shell 2 at a certain angle, when the fan blade 3 rotates, negative pressure is generated at the inlet end to suck air into the fan, the air is driven between the fan blade 3 and the fan blade shell 2 to generate centrifugal force, the air is thrown out of the fan under the action of the shearing force and the thrust force of the fan blade 3 with the angle, the air between the two fan blades 3 forms rotating air under the action of the centrifugal force and the rotating inertia force, and when the fan works, the rotating air is continuously generated to form constant-current vortex air.
The fan that produces spiral shell whirlwind that this embodiment provided, when driving motor 6 rotates, driving motor passes through shaft coupling 5 and drives drive shaft 4 and rotate, drive shaft 4 rotates and drives fan blade shell support 8, fan blade shell 2 and fan blade 3 are rotatory together, the air is under the effect of the rotatory power of fan blade 3 and fan blade shell 2, produce the whirlwind, the whirlwind produces adsorption under the inertial action, drive peripheral air and debris and rotate together, the air that rotates up plays the stirring effect, it is rotatory to drive peripheral dust also, the rethread exhaust system is arranged dirty air to other purification area. This is in narrow and small region, and the smoke and dust is abominable, in the operating environment that constructor is more, for example during the construction in environment such as boats and ships, as long as fan system work, the fan of this embodiment is outdoor new trend and is inhaled from the import of fan through the pipeline to the fan effect through this embodiment forms rotatory spiral new trend with the air in this region, just is rotatory and drives the dust and rotate together, just as "tornado" form is the same, can effectually discharge narrow and small region's dust, impurity or harmful toxic gas. Specifically, the mechanism of the fan of the present embodiment for generating the spiral wind is as follows: when the drive shaft 4 drives the fan blades 3 to rotate, an effective space is formed between every two fan blades 3, the rotating fan blades 3 extrude the air in the effective space, under the pushing action of the fan blades 3, the air is thrown out by the fan blades 3 rotating at a high speed to form spiral wind, under the action of a plurality of fan blades 3, the air in the space is divided into a plurality of independent spiral wind by the fan blades 3, the spiral wind mutually affects to form airflow similar to the shape of a tornado, and in the airflow rotating at a high speed, three air pressure areas can be formed:
as shown in fig. 6, the 1 st air pressure region 13 is a calm air pressure region. At the center of the spiral wind, the wind blade shells are distributed along the axial direction of the wind blade shells 2, and the air pressure at the position has almost the same difference with the air pressure of the surrounding environment, and is similar to the central zone of the 'tornado'.
The 2 nd air pressure region 14 is a rotating low air pressure region. In the middle of the inner periphery and the outer periphery of the airflow, the airflow is in a low-pressure area formed by obtaining kinetic energy of high-speed rotation after the fan does work. The greater the power of the fan shaft, the greater the rotational speed of the air flow and the lower the corresponding air pressure in the surrounding area. Under the action of both rotation and propulsion, the movement track of the airflow is more forwards and more forwards from the outlet of the fan in the rotating way. And finally stopping the movement after the kinetic energy is exhausted.
The 3 rd air pressure region 15 is an adsorption region. Under the dual action of the spiral low-pressure area and the standard atmospheric pressure, the air in the area is continuously sucked by the air flow formed in the 2 nd air pressure area 14 at the periphery of the air flow formed in the 2 nd air pressure area 14 and obtains the rotation kinetic energy to form a new rotation air flow. In this area, smoke from the surrounding environment or light weight debris on the floor can be agitated.
As shown in fig. 4, as an example, an axial included angle between the fan blade 3 and the fan blade shell 2 is between 15 ° and 80 °. For example, an axial included angle between the fan blade 3 and the fan blade shell 2 may be 30 °, 40 °, 50 °, 60 °, or 70 °, or may be other included angle values, and specifically, the selection of the included angle may be determined according to a design value of the fan.
As shown in fig. 3, for example, seven blades 3 are uniformly fixed along the circumferential direction of the blade shell 2. Seven fan blades 3 are arranged, and the design can effectively reduce wind noise generated when the fan runs.
As shown in fig. 2 and 6, for example, six blade shell brackets 8 are provided at the front end and the rear end of the blade shell 2 in the circumferential direction of the blade shell 2.

As shown in fig. 4, as a preferred example, the front end and the rear end of the housing 1 are provided with protective covers 10 to protect the fan from being damaged by foreign matters sucked in during operation.
As shown in fig. 3 and 4, as a preferred example, the blower generating the spiral wind further includes a driving motor fixing bracket 7, and one end of the driving motor fixing bracket 7 is connected to the driving motor 6, and the other end is connected to the housing 1. The reverse torque generated by the driving motor 6 can be transmitted to the housing 1 through the driving motor fixing bracket 7. More preferably, 3 driving motor fixing brackets 7 are uniformly arranged along the circumferential direction of the housing 1.
