[0038] The other end of the frame is provided with a vibrating plate 430, and the vibrating module is used to realize the vibration of the filter module by driving the vibrating plate 430.

[0039] The specific structure of the vibrating module is as follows: a support plate 440 is arranged below the vibrating plate 430, a group of vertical guide rods 450 are arranged on the support plate 440, and a group of springs 460 are sleeved on the guide rods 450 between the vibrating plate 430 and the support plate 440.
