An adapter for a suction device consists of a container (10), an anti-leak base (20) mounted on the container (10), a liquid level controller (30) attached to the anti-leak base (20) and inserted into the container (10) and a cap (40) to hold the anti-leak base (20) inside and detachably attach to the container (10). A liquid nipple and an air nipple are formed on the cap (40), and a knob (70) is rotatably mounted on the cap (40). The anti-leak base (20) has a division wall (23) with an outer periphery extending up from part of the edge and a liquid guide trench (24) in the outer periphery to operationally align with the liquid nipple (41). By turning the knob (70), the division wall (23) is aligned to block the liquid nipple (41) tightly to provide an excellent seal. |
