Disclosed is an air control device, comprising an air pump (3) and at least one electromagnetic valve (2), and further comprising a connecting piece (1), wherein the connecting piece (1) is provided with at least one first airflow passage (11) and at least one second airflow passage (12), an air inlet end of the first airflow passage (11) is sheathed with an air outlet (31) of the air pump (3)in a sealing manner, an air outlet end of the first airflow passage (11) is sheathed with an air inlet (21) of the electromagnetic valve (2) in a sealing manner, an air inlet end of the second airflow passage (12) is sheathed with the air outlet (31) of the electromagnetic valve (2) in a sealing manner, and an air outlet end of the second airflow passage (12) opens into the outside. The present invention adopts a connecting piece to realize the connection fit of an air pump and an electromagnetic valve, thereby not only solving the problem of difficult and complex connection caused by the inconsistent calibre sizes of the air pump and the electromagnetic valve, but also making the structure of the whole assembly after installation more compact with less occupied space. |
