The utility model discloses a pressure sensor packaging structure, which relates to the technical field of pressure sensors, and comprises a substrate and a packaging shell, two sides of the top of the packaging shell are connected with a first labyrinth ring and a second labyrinth ring, an ash storage groove is arranged between the first labyrinth ring and the second labyrinth ring, the second labyrinth ring is sleeved with a labyrinth frame, and the labyrinth frame is sleeved with an ash storage groove. And a filter screen is connected into the labyrinth frame. Through the arrangement of the first labyrinth ring, the second labyrinth ring, the ash storage groove, the labyrinth frame and the filter screen, the first labyrinth ring, the second labyrinth ring and the labyrinth frame are matched to form a shorter labyrinth, so that part of impurities can be separated through centrifugal force when airflow passes through the labyrinth, and the filter screen can block large-particle impurities; the intercepted impurities can fall into the ash storage groove, more impurities can be contained in the ash storage groove, the phenomenon that airflow passing is affected by accumulated dust is reduced, and therefore the cleaning interval is prolonged; and most of large and medium particle impurities are effectively taken out, so that the blockage of the waterproof breathable film is slowed down.

This invention discloses a method for the coordinated removal of products from near-atomic-scale electrochemical machining, along with its system apparatus and applications. The core of this method lies in the synergistic use of chemical complexation, pulsed electric field modulation, and interfacial electrostatic repulsion to proactively address the problem of product blockage within near-atomic-scale machining channels. Specifically, by adding a strong complexing agent to the electrolyte, the metal ions generated during machining are converted in situ into soluble complexed anions. A composite waveform, including an anodic pulse during machining, a zero-potential intermittent period during diffusion, and a reverse cathode pulse during impurity removal, provides dual impurity removal momentum through diffusion and electromigration. Simultaneously, the inner wall of the ion channel protein is negatively modified to reduce product transport resistance and adsorption through electrostatic repulsion. The synergistic effect of these three mechanisms enables effective and continuous product management without compromising machining locality. Correspondingly, this invention also provides a dedicated machining system for implementing this method and its application in the machining of easily passivated metal materials.
