The invention relates to a resonant sound absorbing structure of an electric breast pumping device. The resonant sound absorbing structure includes a regulating valve connected to the suction pipe ofthe cylinder, the regulating air valve is connected with one end of the resonator through a connecting pipe, The other end of the resonator is connected with one end of the inlet and outlet pipe, andthe suction pipe is communicated with the connecting pipe. The resonator comprises a resonant cavity body and a pipe connecting head arranged at both ends of the resonant cavity body, and a pluralityof air columns are arranged inside the resonant cavity body. The resonant sound absorbing structure has reasonable structure and designed a resonance structure, which can effectively consume sound energy, reduce noise and improve the use effect of the electric breast pumping device. 本发明涉及种电动吸乳器的共振吸声结构，包括与气缸的吸气管相连的调节气阀，所述的调节气阀通过连接气管与共振器的端相连，该共振器的另端与进出气管的端相连，所述的吸气管与连接气管相连通，所述的共振器包括共振腔体和布置在共振腔体两端的气管连接头，所述的共振腔体的内部布置有若干个空气柱。本发明结
