Description

technical field [0001] The invention relates to an electronic display, in particular to a weighing display used on an electronic scale. Background technique [0002] The weighing indicator is provided with a display screen and buttons, which can operate the electronic scale and display the value of the electronic scale. The existing weighing display has no waterproof measures, or the waterproof measures are not comprehensive, especially the power plug part and signal plug part on the weighing display, because it involves external connection, it is difficult to achieve sealing; there is also a power switch part, due to This is a movable part, so it is also difficult to seal. When electronic scales are used to weigh wet goods with water, moisture can easily enter the inside of the weighing indicator, causing the internal circuit to be damaged by moisture. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a weighing display...
