A sputum suction tube (100) for oral care comprises a housing (1), a water suction tube (2), a water intake tube (3), a toothbrush head (4), and a switch (5) capable of controlling the traffic of the water suction tube (2). The water suction tube (2) and the water intake tube (3) are mounted in the housing (1). The toothbrush head (4) is mounted on the far end of the housing (1). The far end of the water suction tube (2) is connected to the far-end inner-port of the water suction tube (2) disposed on the far end of the housing (1), and the far end of the water intake tube (3) is connected to the far-end inner-port of the water intake tube (3) disposed on the far end of the housing (1). A water suction opening (4-1) formed on the toothbrush head (4) is corresponding to a water suction opening (1-10) formed on the housing (1), and a water intake opening (4-2) formed on the toothbrush head (4) is corresponding to a water intake opening (1-9) formed on the housing (1). The switch (5) is mounted in a switch mounting groove (1-5) formed in a hand-held portion of the housing (1). The switch (5) comprises a rolling wheel (5-1) and a slope plate (5-2). The rolling wheel (5-1) is mounted in the switch mounting groove (1-5), and the water suction tube (2) is mounted between the rolling wheel (5-1) and the slope plate (5-2). Because the water suction tube (2) and the water intake tube (3) are separated, sucked sputum flows away through a sealed passage, thereby avoiding cross-infection. By using a rolling-wheel-type switch structure, the sputum suction tube for oral care is normally located in a suction-out state, and undesired choke when a mouth cavity is cleaned is effectively avoided, thereby providing higher safety.La présente invention concerne un tube d'aspiration d'expectoration (100) pour des soins bucco-dentaires comprenant un boîtier (1), un tube d'aspiration d'eau (2), un tube d'admission d'eau (3), une tête de brosse à dents (4), et un commutateur (5) capable de com
