In one embodiment, the present disclosure provides a portable nebulizer comprising a housing, a mouthpiece, a reservoir, a disk having multiple pores, and a unit that is configured to cause the disk to vibrate, wherein the vibration of the disk creates a pressure differential that causes a fluid from the reservoir to move through the disk to create an aerosol for delivery. In one embodiment, the mouthpiece may be held in place with at least one metal plate imbedded in the mouthpiece and at least one magnet imbedded in the housing. In one embodiment, the reservoir may have a non-cylindrical shape. In one embodiment, the nebulizer may comprise a battery and a USB port for charging the battery.在一項實施例中,本發明提供一種可攜式噴霧器,其包括一外殼、一口型件、一貯槽、具有多個孔之一圓盤,及經構形以使該圓盤振動之一單元,其中該圓盤之該振動產生使一流體自該貯槽移動通過該圓盤以產生用於遞送之一氣膠之一壓力差。在一項實施例中,該口型件可係用經嵌入於該口型件中之至少一個金屬板及經嵌入於該外殼中之至少一個磁體來固持於適當位置中。在一項實施例中,該貯槽可具有一非圓柱形形狀。在一項實施例中,該噴霧器可包括一電池及用於充電該電池之一USB埠。1‧‧‧前殼2‧‧‧頂部零件3‧‧‧底部零件4‧‧‧組件5‧‧‧後殼6‧‧‧前零件7‧‧‧後零件8‧‧‧鉸接蓋9‧‧‧蓋閂10‧‧‧貯槽塞/栓11‧‧‧塞12‧‧‧可撓開關頂蓋20‧‧‧外殼30‧‧‧口型件40‧‧‧貯槽
