When the mounting plate moves to the point where it is about to contact the side wall of the dust storage chamber, the second magnetic block is attracted by the first magnetic block, causing the first vibrating rod to move toward the mounting plate, generating an impact force on the side plate, and shaking the dust on the surface of the side plate into the dust storage chamber, thereby facilitating the cleaning of the surface of the side plate and the continuous use of the side plate.

[0019] (4) In the present invention, after air enters the first exhaust pipe, as the air pressure inside the first exhaust pipe increases, the block is pushed downward, and then the baffle is driven downward, so that the flow slot moves to the inside of the water inlet pipe, thereby opening the water inlet pipe. At this time, the fire hydrant can discharge water. When there is no fire, the baffle closes the water inlet pipe, achieving the purpose of self-locking the fire hydrant, thereby avoiding misuse of the fire hydrant and improving the protection effect on the building.

[0036] After the first filter hole 603 filters the large dust in the smoke, the dust adheres to the back of the smoke exhaust chamber 601, which is easy to block the first filter hole 603. At this time, the motor 703 is turned on. The motor 703 is a forward and reverse motor, thereby driving the mounting plate 705 to move back and forth between the two dust storage chambers 604. During the movement of the mounting plate 705 inside the smoke exhaust chamber 601, the top rod 719 is continuously subjected to the pressure of the top block 720, so that the movable plate 716 moves back and forth under the action of the top block 720 and the movable block 711, so that the second vibration rod 718 continuously vibrates the inner wall of the smoke exhaust chamber 601, thereby shaking the dust attached to the inner wall of the smoke exhaust chamber 601 to the bottom wall of the smoke exhaust chamber 601, and then the dust is swept into the dust storage chamber 604 by the cleaning brush 706, thereby avoiding the first filter hole 603 from being blocked and improving the smoke exhaust effect;

[0037] During the movement of the mounting plate 705, the side plate 707 continuously contacts the smoke entering the smoke exhaust chamber 601, so that the second filter hole 708 blocks the dust in the smoke, and the second filter hole 708 filters the smoke. When the mounting plate 705 moves to the inside of the dust storage chamber 604 and is about to contact the side wall of the dust storage chamber 604, the second magnetic block 712 is attracted by the first magnetic block 709, so that the first vibration rod 713 moves toward the mounting plate 705, generating an impact force on the side plate 707, thereby shaking the dust on the surface of the side plate 707 into the inside of the dust storage chamber 604, thereby facilitating the discharge of smoke and dust.

[0038] The water outlet control assembly 9 includes a valve body 901 installed on the water inlet pipe 8, the valve body 901 is located below the first exhaust pipe 607, the valve body 901 is slidably connected to a baffle 902, the baffle 902 is provided with a flow slot 903, the flow slot 903 is located above the water inlet pipe 8, a pressure rod 904 is installed at the top of the baffle 902, the pressure rod 904 penetrates to the top of the valve body 901, a pressure plate 905 is installed at the top of the pressure rod 904, and a first exhaust pipe 607 is installed at the bottom of the pressure plate 905.
