when the novel fan is used, the motor 41 is electrified to operate and drives the first gear 42 to rotate, the first gear 42 drives the fan blades 3 to rotate through the gear ring, and the fan blades 3 are used for guiding fresh air into the ventilator 1 and entering a space area used by gas through the ventilator 1 so as to achieve the purpose of diluting the gas concentration in the area.
Can repel the magnet piece when electromagnet 46 is switched on, utilize this repulsion force to promote fixed column 49 and remove in recess 48 to promote toper piece 410 to the tapered slot of card income linkage piece 51 in, reach coordinated control subassembly 5 that keeps out the wind, toper piece 410 is gone into to the tapered slot in, and antiskid cover 411 can increase the coefficient of friction between toper piece 410 and the tapered slot inner wall, makes toper piece 410 rotatory ability drive second pivot 52 rotatory through linkage piece 51.
The rotating second rotating shaft 52 drives the first bevel gears 53 to synchronously rotate, the first bevel gears 53 drive the pair of second bevel gears 54 to rotate, each second bevel gear 54 drives the threaded column 55 connected with the second bevel gear to synchronously rotate, the threaded column 55 can stably rotate under the action of the third rotating shaft 56 and the bearing of the third rotating shaft, the rotating motion of the threaded column 55 is converted into the axial motion of the threaded cap along the threaded column 55, the third fixing rod 58 is driven by the connecting block 57 to move along the limiting groove under the limiting action of the limiting block and the limiting groove, the third fixing rod 58 drives one end of the wind-blocking cloth 59 to move, so that the wind-blocking cloth 59 can contract or expand, the movement of the wind-blocking cloth 59 can control the adjustment of the sheltered area of the vent 7, further the ventilation volume can be controlled, and the purpose of controlling the dilution of the gas concentration is achieved.
Meanwhile, when the first gear 42 rotates, the fourth rotating shaft 82 can be driven to synchronously rotate through the second gear 81, the fourth rotating shaft 82 drives the reciprocating lead screw 83 to rotate, the rotation of the reciprocating lead screw 83 is converted into axial motion of the lead screw cap along the reciprocating lead screw 83, the lead screw cap drives the first fixing rod 84 to linearly move, and the first fixing rod 84 drives the first connecting plate 85 to synchronously move so as to adjust the distance between the first connecting plate 85 and the second connecting plate 812. Leading-in water source of aqueduct 6 sprays through a plurality of dispersion nozzles 88, under the effect of articulated piece 89 and intercommunication hose 810, the interval change of first connecting plate 85 and second connecting plate 812 enables first dust fall pipe 87 and second dust fall pipe 813 and takes place relative rotation in the horizontal plane, makes the position of a plurality of dispersion nozzles 88 change, reaches the purpose that enlarges the spray area, carries out better dust fall effect for the gas region.
The present invention is not limited to the above embodiments, and any modifications, equivalent replacements, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
