The gravity of breathing machine pipeline depends on water collecting cup

The utility model relates to the field of breathing machine auxiliary instruments, in particular to a breathing machine pipeline gravity-dependent water collecting cup which comprises a cup body withan upward opening and a cup cover arranged at the top end of the cup body, two vent pipes are arranged on the cup cover, and the two vent pipes are symmetrically arranged on the two sides of the cup cover in an adhesive mode. Wherein the two breather pipes are respectively communicated with the cup body through the cup cover, a connecting cover is sleeved on the breather pipes, a rotating bearingis arranged between the connecting cover and the breather pipes, the connecting cover is connected with the breather pipes through the rotating bearing, a balancing weight is adhered to the bottom endof the cup body, and a water collection control device is arranged between the cup body and the cup cover. The cup cover and the cup body are connected through the water collection control device. The gravity-dependent water c
