[0007] As a further optimization of the present invention, there are a plurality of connecting blocks, the connecting blocks are arranged between the filter shell and the silencer column shell, there are a plurality of through holes, and the cross-section of the through holes is square.

[0008] As a further optimization of the present invention, the first externally threaded column tube, the connecting ring plate, the transparent column shell, the guide ring, the second externally threaded column tube, the annular adsorption plate and the one-way valve are on the same axis, and the second externally threaded column tube is spirally connected to the exhaust hole.

In the present invention, the noise generated by the exhaust gas can be further eliminated by setting up a filtering and silencing unit to improve the surrounding working environment of the electronic-grade pneumatic pump. At the same time, in the actual application process, the impurities and water vapor can be simply adsorbed by the filter shell to ensure the stability of the overall operation of the device.
