The utility model provides a reciprocating type drying device of an intelligent toilet and belongs to the technical field of sanitary ware. The reciprocating type drying device of the intelligent toilet solves the problem that the position of the conventional drying device is fixed and cannot be adjusted automatically when the conventional drying device is in use. The reciprocating type drying device of the intelligent toilet is arranged on the toile and comprises a bracket, an air inlet component and a reciprocating type drying mechanism for transmitting warm air, wherein the drying mechanism comprises a drying inner pipe, a drying pipe and a power component; the drying inner pipe is fixedly connected with the air inlet component; the drying pipe is sleeved outside the drying inner pipe; the power component can drive the drying pipe to do reciprocating motion along the bracket; and the power component is connected with a central processing unit (CPU) of a main control panel. The drying pipe is sleeved outside the drying inner pipe and can do reciprocating linear motion along the axial direction of the drying inner pipe under the control of the CPU of the main control panel and the power component, so that the position of an air outlet hole of the drying pipe can be adjusted automatically. The reciprocating type drying device of the intelligent toilet has the advantages of sufficient air quantity, high efficiency, capacity of performing reciprocating type drying and reliable performance.
