Title:
LIQUID INJECTOR WITH PRECISE LIQUID OUTPUT
Document Type and Number:
WIPO Patent Application WO/2019/100817
Kind Code:
A1
Abstract:
The invention relates to a liquid injector (2) with precise liquid output, comprising a controller (8), a cavity part (21) and a piston rod (22). The cavity part (21) is provided with a liquid storage cavity (211), a liquid outlet channel (213) and a liquid inlet channel (212) communicating with each other. The cavity part (21) is made of acrylic material, the piston rod (22) is of alumina ceramic material, valves (3) are provided on the liquid outlet channel (213) and the liquid inlet channel (212), and the valves (3) are connected with the controller (8). The cavity part (21) of the acrylic material is not only light in weight, but also has a high heat distortion temperature and does not deform during normal use, thereby avoiding the occurrence of unstable liquid discharge due to deformation of the cavity part (21). The piston rod (22) is made of alumina ceramic material. The piston rod (22) made of alumina not only has high mechanical strength, but also has good high temperature resistance, and does not deform when it is used normally, thereby avoiding the occurrence of unstable liquid discharge due to deformation of the piston rod (22).
