Silencing device of foam material atomizer

The utility model relates to the technical field of muffling devices, in particular to a muffling device of a foam material atomizer, which comprises a muffling shell, one side of the muffling shell is fixedly connected with a pop-up component, the pop-up component comprises a spring, and one side of the spring is provided with a limit groove. Compared with the prior art, the silencer has the advantages that due to the fact that the vacuum chamber is arranged in the silencing shell, noise does not have a transmission medium in the vacuum chamber, the atomization column can prevent the noise from being transmitted out, then thrust is applied to the silencing cover, due to the fact that the force can change the motion state of an object, the metal column can generate a motion trend, and the noise is reduced. When the movement trend is larger than the static friction force between the metal column and the fixing hole, the metal column can move, the silencing shell and the silencing cover can be connected, the so
