The cavity 74 (only shown in FIG. 8) generates positive and negative pressure changes to form the drawing power. As the bellows body 73 of the bellows-type telescopic tube 70 continuously expands and contracts, as shown in FIG. The head 23 (see Figure 2) enters the oil and water flowing along the lower pipe section 22 of the introduction pipe 20 to the upper pipe section 21. During the flow, the check direction is set by the check valve 30, so that the oil and water can only flow from the bottom to the bottom. Pass the inlet pipe 20 upward (as shown by arrow L2) without flowing back, so with the negative pressure generated by each elongation of the bellows body 73, the oil and water in the inlet pipe 20 will produce a In this way, the oil-water extraction function of the power extraction device disclosed in the present invention is achieved; and the present invention uses a bellows-type telescopic cylinder 70 to generate telescopic motion to form a type characteristic of drawing power. Since this structure can be integrated with plastic materials Injection molding, so mass production is very easy, fast and low cost, and its interlocking parts are achieved by eccentric driving members 60 that have simple components and save space in the configuration, which can greatly reduce the number of components of the oil-water separator power extraction device and The volume of the structure is configured, thereby effectively reducing the installation cost and having better extraction benefits.
