The oscillation sheet is fixed between the fixing plate and the nozzle plate and covers the receiving groove. The security assembly includes a fixing component, an elastic component, a fixing element, an anti-detachable component, and a pointed tip extending from a distal end of the anti-detachable component. The security assembly is fixed to the fixing plate, the elastic component and the anti-detachable component are received in the receiving groove with the pointed tip pointed towards the oscillation sheet.
