[0052] In this embodiment, the fastening structure 4 includes a first fastener 41, one end of which is connected to the purification structure 3, and the other end of which is connected to the booster unit 2 through the first connection hole 113.

The end of the first fastener 41 connected to the booster unit 2 passes through the first connection hole 113 and the second connection hole in sequence and is connected to the second fastener 42. The second fastener 42 is fastened to the first fastener 41, providing a more stable connection, preventing misalignment, offset, or shaking between the purification structure 3 and the booster structure, and thus achieving very high reliability.

The first conductive structure 311 is fixedly connected to the first mounting member 11 to enhance stability. The limiting through-hole matches the shape of the head of the metal screw. For example, when the first fastener 41 is a hexagonal screw, the limiting through-hole is a hexagonal columnar through-hole.

[0073] In this embodiment, the retaining structure further includes a second retaining portion 112 protruding from the first mounting member 11. The second retaining portion 112 is a slot-shaped structure that matches the shape of the third conductive connecting portion 3221. A single connection hole secures the second conductive structure 322 to the substrate 321, preventing rotation and disconnection from the adsorption plate 321. Alternatively, the second retaining portion 112 includes at least three protrusions arranged in a triangular pattern, with the third conductive connecting portion 3221 positioned between the three protrusions and constrained by the three protrusions.
