Abstract: The utility model relates to a ventilator with a functional module, belonging to the technical field of ventilator equipment. Customers cannot add or reduce functions in existing ventilator products, which lowers the flexibility of use, generates waste or fails to meet demands, and also increases production cost. In the utility model, a functional component is of an independent modular design: the functional component is independently placed in the module case to become a functional module such that the function can be customized according to demands. The utility model adopts the common micro-USB as a connecting terminal, and the ventilator body is provided with a plurality of micro-USB receptacles as connecting ports, realizing modular plug-and-pull and ensuring random plug-and-pull. Thus, the utility model is simple in connection operation, ensures plug-and-pull, is easy to identify, avoids mis-connection, and increases safety.
