description The invention discloses an emptying structure of a self-suction pipeline of a high-pressure cleaning machine, which comprises an emptying pipe connected to an outlet of a pump body pipeline, a multi-section-shaped hole cavity is axially formed in the emptying pipe in a penetrating manner, a cylindrical body is radially formed on the emptying pipe, an emptying valve cavity vertically communicated with the hole cavity is formed in the cylindrical body, and the emptying valve cavity is communicated with the hole cavity. An emptying valve for realizing air discharge and liquid backflow by utilizing the mass difference of air and liquid is mounted in the emptying valve cavity; and the emptying valve is formed by assembling an emptying valve core, an emptying valve spring and an emptying valve nut. The self-suction device is reasonable in design and convenient to install, the self-suction time can be shortened to the maximum extent, part abrasion is reduced, and the service life of the cleaning machine is prolonged
