    • PURPOSE: A substrate having a bypass valve structure, an inkjet print head and a micro pump are provided to enhance the discharge performance of ink since after discharging ink, flow resistance occurs on the flow of the ink flowing back to a flow path of an inkjet print head. CONSTITUTION: A substrate having a bypass valve structure(200) comprises a slant path(250), and bypass flow paths(240,260). The slant path connects a first straight part to a second straight part. The bypass flow paths are communicated with at least one of the first straight part(220) and a second straight part(280). The bypass flow paths are formed in a curved shape. The first straight part and the second straight part are repetitively connected by the slant path. The first straight part and the second straight part are respectively communicated with the bypass flow paths. The first straight part and the slant path are respectively formed on different substrates. The first straight part and the second straight part are formed on a first substrate.
    • 目的:提供具有旁通阀结构的基板,喷墨打印头和微型泵,以提高油墨的排出性能,因为在排出墨后,流过墨水的流动回到喷墨打印机的流动路径 打印头。 构成:具有旁通阀结构(200)的基板包括倾斜路径(250)和旁路流路(240,260)。 倾斜路径将第一直线部分连接到第二直线部分。 旁通流路与第一直线部分(220)和第二直线部分(280)中的至少一个连通。 旁路流路形成为弯曲形状。 第一直线部分和第二直线部分通过倾斜路径重复连接。 第一直线部分和第二直线部分分别与旁路流路连通。 第一直线部分和倾斜路径分别形成在不同的基板上。 第一直线部分和第二直线部分形成在第一基板上。
