As shown in fig. 1 to 4, a modular fan for increasing wind pressure includes a fan module 1 and a driving module 2; the fan module 1 comprises a main frame 11 and a mounting seat 12, wherein a limiting opening 121 is formed in the side wall of the mounting seat 12; the driving module 2 comprises a driving main body 21 and a limiting block 22 extending along the side surface of the driving main body 21, the driving main body 21 is circular, the limiting block 22 is arc-shaped, and a first air guide inclined surface 221 is arranged on the outer side of the limiting block 22; the driving module 2 is detachably mounted on the fan module 1, the driving body 21 is disposed in the mounting seat 12, and the limiting block 22 passes through the limiting opening 121 and is erected between the main frame 11 and the mounting seat 12.

Specifically, firstly, the driving module 2 is installed at a position, corresponding to the fan motor, on one side where the fan module 1 blows air, the driving module 2 is set to be circular and is close to the fan motor in shape and size, and the design can avoid influence on air output caused by the fact that partial structure on the driving module 2 protrudes to shield air outlet of the fan; and the circular design can also increase the practical usable area of the fan module 1, so that the drive circuit board can be designed to be larger. Secondly, since the mounting seat 12 is provided with the limiting opening 121, the driving main body 21 extends out of the limiting block 22 from the side surface, when the driving module 2 is mounted, the driving main body 21 is aligned with the mounting seat 12, and the limiting block 22 is aligned with the limiting opening 121, so that the driving module 2 can be quickly positioned, and the problem that alignment and butt joint are difficult to achieve due to the round design of the driving main body 21 during mounting is solved; then, the driving main body 21 is placed into the mounting seat 12, the limiting block 22 penetrates through the limiting opening 121 and is erected between the mounting seat 12 and the main frame 11, the driving module 2 and the fan module 1 can be assembled after the limiting block 22 is fixed, and the limiting block 22 also plays a role in connecting and supporting the mounting seat 12 and the main frame 11. Furthermore, the limiting block 22 is set to be arc-shaped, so that the resistance to the airflow is smaller than that of a straight design, and the rotating airflow blown out by the fan is guided, so that the turbulence is reduced, and the air outlet pressure of the fan is increased; still be provided with first wind-guiding inclined plane 221 on the stopper 22, reduced the area of contact of stopper 22 with the air current, avoid the air current to be obstructed, the stopper 22 of being convenient for cuts the air current and realizes the guide effect, reduces the turbulent flow, further increases the pressure of fan air-out to avoided air current and stopper 22 surface vertical collision to kick-back and played the effect of noise reduction. In addition, drive module 2 and fan module 1 detachable connected mode, the drive module 2 of being convenient for to change different power modes, and then improve the operating efficiency of fan. This modularization fan's simple structure is practical, and reasonable in design is ingenious, the quick location installation of being convenient for, stopper 22 realizes location, joint support, wind-guiding cutting, increases a plurality of functions of atmospheric pressure, noise reduction, and the practicality is high, and use value is high.

Further, a PCB is arranged in the driving main body 21, a lead is arranged in the limiting block 22, and the lead is electrically connected with the PCB. The driving main body 21 and the limiting block 22 extending along the side face of the driving main body 21 form an integrated design, so that the wire and the PCB are wrapped and protected, the connecting part of the wire and the PCB is prevented from being damaged and broken, and the service life is prolonged; and the wiring arrangement of the fan is more concise and clearer.

Further, the fan module 1 further includes fan blades 13, the fan blades 13 are arranged in an arc shape, and the arc shape of the fan blades 13 and the arc shape of the limiting block 22 are arranged in opposite directions. The radian of the fan blades can enable blown air flow to be concentrated in a columnar space right in front of an air outlet, so that air pressure can be increased; and because the arc direction of flabellum 13 sets up with the arc direction of stopper 22 is opposite, the air current direction of rotation that produces when flabellum 13 operates is opposite with the arc direction of stopper 22, is convenient for stopper 22 to cut the direction to the air current, reduces the turbulent flow, increases the wind pressure.

Further, a plurality of flow guide supporting pieces 14 are further arranged between the main frame 11 and the mounting seat 12, the plurality of flow guide supporting pieces 14 are arranged in an arc shape with a bending angle, and the arc shape of the plurality of flow guide supporting pieces 14 is opposite to the arc shape of the fan. On one hand, the flow guide supporting pieces 14 play a role in connecting and supporting the mounting seat 12; on the other hand, since the guiding support member 14 is set to be in the shape of an arc of a bend and the arc of the guiding support member 14 and the arc of the fan are set in opposite directions, the rotation direction of the air flow generated when the fan blades 13 operate is opposite to the arc direction of the guiding support member 14, so that the limiting block 22 can conveniently cut and guide the air flow, reduce turbulence and increase wind pressure.

Further, the fan module 1 further includes an air inlet 101 and an air outlet 102, and the sides close to the air inlet 101 and the air outlet 102 are both provided with a second wind guiding inclined plane 15. The contact area between the air inlet 101 and the air outlet 102 and the airflow is increased, so that the air intake and the air output of the fan are increased, and the air pressure is increased; and the effect of reducing noise caused by the vertical collision and rebound of the air flow of the air inlet 101 and the main frame 11 is avoided.

Further, the fan module 1 is provided with a fastening hole 103, and the driving body 21 and the limiting block 22 are both provided with a fastening 201, so as to detachably connect the driving module 2 and the fan module 1. The snap-in connection eliminates the troublesome process of screwing the screw to install, and the driving module 2 and the fan module 1 can be assembled or disassembled quickly.

For the embodiments of the present invention, it should be further explained that, under the condition of no conflict, the features in the embodiments and embodiments of the present invention can be combined with each other to obtain a new embodiment.
