[0013] A plurality of valve plates are slidably mounted in the plurality of rectangular holes, and the valve plates are used to control the opening and closing of the blowing pipe;

[0014] The locking mechanism is provided on the diverter box and is used to lock the valve plate.

[0015] Preferably, the steering mechanism includes a base arranged below the fan box body, a rotating cavity is opened on the base, a rotating column is rotatably installed on the bottom inner wall of the rotating cavity, and the top of the rotating column extends to the top of the base and is fixedly connected to the bottom of the fan box body.

[0016] Preferably, the outer fixed sleeve of the rotating column is provided with a driven gear.

[0017] Preferably, a motor is fixedly mounted on the inner wall of the bottom of the rotating chamber, a driving gear is fixedly mounted on the output shaft of the motor, and the driving gear is meshed with the driven gear.

[0018] Preferably, two locking grooves are provided on one side of each of the plurality of valve plates.

[0029] The technical solution of this embodiment will be clearly and completely described below in conjunction with the drawings in this embodiment. Obviously, the described embodiment is only a part of this embodiment, rather than all the embodiments. Example

[0030] Reference Figure 1-Figure 3 , a fire protection ventilation fan box without volute, comprising:

[0031] Fan box body 1;

[0032] A steering mechanism, connected to the fan box body 1, for driving the fan box body 1 to turn;

[0033] The air inlet 2 and the air outlet 3 are respectively arranged on both sides of the fan box body 1;

[0034] The diverter box 4 is fixedly connected to the air outlet 3;

[0035] A plurality of blowing pipes 5 are respectively fixedly connected to the outside of the diversion box 4;

[0036] A plurality of rectangular holes 6 are provided on the top of the diverter box 4;

[0037] A plurality of valve plates 7 are slidably mounted in the plurality of rectangular holes 6 , and the valve plates 7 are used to control the opening and closing of the blowing pipe 5 ;

[0038] The locking mechanism is provided on the diverter box 4 and is used to lock the valve plate 7 .

[0039] In this embodiment, the steering mechanism includes a base 13 arranged below the fan box body 1, a rotating chamber 15 is opened on the base 13, and a rotating column 14 is rotatably installed on the bottom inner wall of the rotating chamber 15. The top of the rotating column 14 extends to the top of the base 13 and is fixedly connected to the bottom of the fan box body 1.
