Atomizer flow guide pipe, atomizer flow guide pipe assembly and atomizer

Two groove bodies which are symmetrically arranged relative to the axial direction of a pipe body are formed in the inner wall of the pipe body, the two groove bodies penetrate through one end wall of the pipe body, openings are formed in the end wall, and two embedded assemblies are embedded into the two groove bodies through the two openings respectively and restore flow guide holes. The first connecting part and the second connecting part extend to the opening side from the bottom of the groove body and are sequentially arranged in the axial direction of the pipe body, the first connecting part is close to the outer wall of the pipe body, the second connecting part specifically comprises a plurality of first connecting units and a plurality of second connecting units, and the first connecting units and the second connecting units are sequentially arranged in the axial direction of the pipe body at intervals; the first connecting part and the plurality of first connecting units are made of high-temperature-
