A sliding groove is provided on the side of the connecting block 102 away from the connecting plate 101. A limiting shaft is provided in the sliding groove. A sliding block 103 is sleeved on the surface of the limiting shaft. A support plate 104 is fixedly connected to the side of the sliding block 103 away from the connecting block 102. A mounting plate 105 is fixedly connected to one side of the support plate 104. Through holes are provided on both sides of the mounting plate 105.

[0029] The main body 2 includes a body 201. A stabilizing plate 202 is fixedly connected to one side of the body 201. A stabilizing frame is fixedly connected to the side of the stabilizing plate 202 away from the body 201. A control box 203 is fixedly connected inside the stabilizing frame. A cover 204 is fixedly connected to one side of the control box 203.
[0030] An air vent is provided at the bottom of the cover 204, and a dustproof net is provided at the air vent. The dustproof net is fixedly connected to the cover 204.
[0031] The silencing mechanism 3 includes a first silencing plate 301, a silencing block 302 fixedly connected to the side of the first silencing plate 301 away from the body 201, a second silencing plate 303 fixedly connected to the side of the silencing block 302, a connecting column provided on the side of the first silencing plate 301, and the first silencing plate 301 and the second silencing plate 303 fixedly connected by the connecting column.
[0032] The first silencer plate 301 and the second silencer plate 303 are symmetrically distributed through the body 201, and there are four of each.
[0033] The implementation principle of one embodiment of this application is as follows: When the ventilation and air conditioning system is started and running, the air flows in the system, and the noise generated spreads to all directions. The noise first reaches the first silencer plate 301, and the high-frequency noise is initially blocked by the first silencer plate 301. Subsequently, the remaining noise enters the silencer block 302. Inside the silencer block 302, after multiple reflections and scattering, the noise energy of different frequencies is absorbed in large quantities. Finally, the noise after being processed by the silencer block 302 reaches the second silencer plate 303. The second silencer plate 303 further blocks the remaining noise and reduces the noise intensity to a low level, thereby effectively reducing the impact of the noise generated by the ventilation and air conditioning system on the surrounding environment. During the operation of the ventilation and air conditioning system, the control box 203 in the main structure 2 controls and monitors the entire silencer device. The stabilizing plate 202 and the stabilizing frame ensure that the control box 203 is in a stable working state and is not affected by the vibration of the ventilation and air conditioning system. At the same time, the dustproof net at the air outlet on the cover 204 prevents dust from entering the control box 203 and ensures the normal operation of the electrical components inside the control box 203.
