Patent number: 11129416Abstract: An electronic cigarette has an installing cavity formed at a bottom of the oil chamber, and a first internal thread arranged on an inner wall of the installing cavity. The glass guiding pipe has a pipe body and a flange sleeved and fixed on the pipe body, a first external thread connected with the first internal thread is arranged on a lateral side of the flange. The atomization core has a glass heating coil and an atomizing medium arranged at a top of the glass heating coil. Oil guiding holes are arranged on the flange, the oil guiding holes guide oil to the atomization core. An opening corresponding to the oil guiding hole is arranged on an inner wall of the oil chamber. A through-hole corresponding to the pipe body is arranged through a lengthways in the oil chamber, the through-hole connected with the installing cavity.Type: GrantFiled: January 7, 2020Date of Patent: September 28, 2021Assignee: Ygreen, Inc.Inventor: Guolin Yuan

Patent number: 10919334Abstract: An anti-counterfeiting pattern having an optically variable structure, comprising lithographic lines and gravure blind embossed relief lines printed on a carrier. The lithographic lines are a set of lithographic curve lines having a curvature, the widths of the lithographic curve lines changing from thick to thin, or thin to thick. The gravure blind embossed relief lines are a set of curve lines corresponding to the lithographic lines, and having the same curvature. The relief lines are overprinted on the lithographic lines with a width variation identical to that of said lithographic lines. Accurate overprinting of the two printing types forms a curved relief structure wherein the width of the lines changes continuously. When a printed product is rotated and observed, a continuously variable optical effect will be seen, which is visual, readily to identify, anti-copying and difficult to forgery.Type: GrantFiled: December 29, 2018Date of Patent: February 16, 2021Assignees: CHINA BANKNOTE INK CO., LTD., CHINA BANKNOTE PRINTING AND MINTING CORPORATIONInventors: Xing Zhang, Qingfei Meng, Yong Zhang, Xiaoquan Zhou, Guolin Yuan, Shifan Zhang
