An annular inner cavity 21 is arranged inside the annular air pipe 2, an air inlet 22 communicated to the annular inner cavity 2 is arranged at the lower end of the annular air pipe, and an air outlet 23 is arranged on the outer side wall of the annular air pipe. The annular air pipe 2 is fixedly arranged at the upper end of the inner cavity of the urinal 1 (the gluing fixing mode can be selected), and is matched with the edge contour of the upper end of the inner cavity of the urinal 1 (the matching means that the outer side wall surface of the annular air pipe 2 is mutually attached to the inner side wall surface of the urinal 1).
The air exhaust joint 3 is arranged in the joint mounting hole 11 of the urinal 1, one end of the air exhaust joint is detachably connected to the air outlet 23 of the annular air pipe 2, and the other end of the air exhaust joint extends out of the urinal 1.
The two ends of the air duct 4 are respectively provided with an air inlet and an air outlet, the air duct 4 is arranged on the wall of the toilet, the air inlet is communicated to the inside of the toilet, and the air outlet is communicated to the outside of the toilet.
The exhaust fan 5 is fixedly arranged in the air duct 4.
One end of the connecting pipe 6 is connected with the exhaust joint 3, and the other end is communicated with the air inlet of the air duct 4.
Preferably, when the urinal 1 is a toilet bowl, the outer wall of the upper end of the urinal 1 is provided with a vent hole 12 communicated with the inner cavity of the urinal 1. When the user sits on the toilet bowl like the lavatory, the user's buttock probably covers the uncovered complete in toilet bowl upper end, makes the inner chamber of toilet bowl form a relatively sealed space, and this will lead to exhaust fan 5 to bleed air the difficulty, and the setting of air vent 12 can be convenient for during the outside air admission toilet bowl inner chamber of toilet bowl, ensures that exhaust fan 5 can bleed air smoothly.
Preferably, the annular air duct 2 is a split structure, which includes an annular groove member 24 and an annular upper cover 25. The upper end of the annular groove member 24 is provided with an annular opening. An annular upper cover 25 is removably mounted at an annular opening at the upper end of the annular channel member 24. When the annular upper cover 25 is mounted on the annular opening of the annular groove member 24, the annular opening is closed, and when the annular upper cover 25 is removed, the annular opening is opened.
Preferably, the lower end of the annular upper cover 25 is provided with two sets of oppositely arranged positioning sheets 251, and when the annular upper cover 25 is covered on the annular opening at the upper end of the annular trough member 24, the two sets of positioning sheets 251 of the annular upper cover 25 respectively form transition fit with the inner side walls of two sides of the annular trough member 24.
