As shown in fig. 1 to 5, the novel smoke guide machine in this embodiment includes an air guide pipe 1100, a controller 1200 and a fan 1300, an air outlet 1101 is formed on an upper end surface of the air guide pipe 1100, the fan 1300 is a centrifugal fan, an air outlet of the fan 1300 is communicated to one end of the air guide pipe 1100, the other end of the air guide pipe 1100 is plugged onto the controller 1200, a plurality of air guide devices are arranged inside the air guide pipe 1100, and the air guide devices are used for guiding an air flow generated by the fan 1300 to be vertically discharged upwards; both ends of the controller 1200 are connected with an air guide pipe 1100, and the air guide pipe 1100 and the controller 1200 are connected into a rectangular structure with an opening on one side or an annular structure with an opening on one side.

According to the scheme of the embodiment, a centrifugal fan blows air into the air guide pipe 1100, so that the air pressure in the air guide pipe 1100 is increased, high air pressure can extrude out of the air guide pipe 1100 through the air outlet 1101 under the guiding action of the air guide device, and the air guide device can guide the obliquely blown air flow to blow out vertically upwards, so that a vertical air curtain is formed; this device simple structure adopts centrifugal fan, compares in cross-flow fan cost cheaper, has solved the problem that centrifugal fan can't effectively produce the air curtain moreover.

The controller 1200 in this embodiment is used to control the on and off of the fan 1300 and the air output of the fan 1300, and the controller 1200 is provided with buttons such as a switch and an indicator light, and a transformer and a control circuit board are arranged inside the controller.

In this embodiment or other embodiments, two sides of the air outlet 1101 are bent toward the inside of the air duct 1100 to form mounting portions 1102, the air outlet 1101 is a gap between the two mounting portions 1102, and the air guiding device is fixed to the mounting portions 1102. This setting not only can provide the mounted position for air ducting, and installation department 1102 can also play the effect of strengthening rib, improves the stability and the compressive capacity at guide duct 1100 top, prevents to pound and warp because of the pan.

In this embodiment or other embodiments, the wind guiding device includes a wind guiding strip 1410 and a wind disturbing plate 1420, the wind guiding strip 1410 includes a plurality of wind guiding blocks 1411 connected in series, the wind guiding blocks 1411 are vertically arranged and arranged at a certain distance, and the wind guiding strip 1410 is fixed between two of the mounting portions 1102; the wind-disturbing plates 1420 are vertically disposed and mounted on the mounting portion 1102 below the wind-guiding strips 1411. The wind sent into the wind guide pipe 1100 by the fan 1300 flows forwards in the wind guide pipe 1100 due to the action of dynamic pressure, and when the wind is sent out from an air outlet, the wind flows obliquely upwards at an angle of 30-45 degrees instead of right angles due to the action of kinetic energy, in the embodiment, the wind obliquely blown out of the wind guide pipe 1100 is corrected to be blown out vertically upwards by utilizing the guiding action of the wind guide block 1411 in the wind guide strip 1410, and as shown in fig. 3, the wind flows along the direction of an arrow, so that a perfect wind curtain is formed, and the integrity of the wind curtain is ensured;

because the air blown out by the fan 1300 has a certain flow velocity after entering the air guide pipe 1100, especially the air flow velocity is the highest near the fan 1300, the air near the fan 1300 can be sucked into the air guide pipe 1100 through the bernoulli principle, and the air flow can be discharged upwards far away from the fan 1300, so that a complete air curtain cannot be formed, or the width of the air curtain is insufficient, and the closer to the tail end of the air guide pipe 1100, the larger the static pressure of the air is, the more the air output is, and the uniform air curtain cannot be formed. The air baffle 1420 is used to reduce dynamic pressure in the air duct 1100, increase static pressure, stabilize air flow, and finally achieve uniform delivery of air entering the air duct 1100 from the air outlet 1101 to form an air curtain.

The air disturbance plate 1420 divides the air outlet 1101 into a plurality of air outlets, under the blocking of the first air disturbance plate 1420, part of the air is blown out from the first air outlet, but because the air outlet is not infinite, only a proper amount of air escapes from the air outlet, more air continues to flow forward under the action of the air pressure and the dynamic pressure, under the action of the second air disturbance plate 1420, the air is blown out from the second air outlet, and so on, and finally, under the action of all the air disturbance plates 1420, the air is uniformly blown out from each air outlet, so that an air curtain is formed; the spoiler 1420 has both: reduce vibration and reduce noise.

The air guide strip 1410 in this embodiment may be an integrated structure, and is connected and fixed by a connecting strip or the like, or may be a split structure, and is directly fixed to the mounting portion 1102; or the installation part 1102 is a connection strip, and the installation part 1102 is fixed to the exhaust outlet 1101.

In this embodiment or other embodiments, the bottom of the mounting portion 1102 is bent towards a direction away from the air outlet 1101, a clamping portion 1103 is disposed at an end of the mounting portion 1102, and two sides of the air deflector 1420 are mounted on the clamping portion 1103. Fixing the air baffle 1420 to the right below the air outlet 1101 to ensure that the air baffle 1420 can guide the air flow to the air outlet 1101; and the bending direction of the mounting portion 1102 can also function as a guide for the air flow.

In this embodiment or other embodiments, the height and width of the wind-disturbing plate 1420 are smaller than the length and width of the inner portion of the wind-guiding pipe 1100, respectively. Ensuring that there is sufficient space for the airflow to flow to the extreme end of the duct 1100.

In this embodiment or other embodiments, the distance between the wind-disturbing plates 1420 is greater than the distance between the wind-guiding blocks 1411. The number of the air disturbance plates 1420 is less than that of the air guide blocks 1411, so that the kinetic energy of the air flow is prevented from being weakened by the excessive air disturbance plates 1420, and the blocking effect of the air curtain is weakened.

In this embodiment or other embodiments, the wind guide pipe 1100 includes a plurality of wind guide pipe sections 1110, the wind guide pipe sections 1110 are in a straight shape, the wind guide pipe sections 1110 are connected by hollow elbows 1120, and the wind guide pipe sections 1110 are connected by the hollow elbows 1120 into a desired shape.
