| 摘要 |
The present invention relates to a device for detecting bubbles of a vacuum container for manufacturing cosmetic contents, in which bubbles filling a vacuum container can be detected through electrode bar assemblies becoming electrically conductive by using bubbles as a medium when the bubbles fill the vacuum container at a predetermined level or more through providing a plurality of electrode bar assemblies in the vacuum container, in which a positive power source is connected to one electrode bar assembly and a negative power source is connected to the remaining electrode bars or the negative power source is connected to one electrode bar assembly and the positive power source is connected to the remaining the electrode bars. The device includes a vacuum container (100); a stirring device (10); a sensor part (20) installed at an upper end of the vacuum container and including two or more electrode bar assemblies (21), in which the electrode bar assemblies include an electrode bar (21-1) and an insulator (21-2) surrounding an exterior of the electrode bar (21-1), one of the electrode bar assemblies (21) is connected to a positive power source and remaining electrode bar assemblies are connected to a negative power source, or one of the electrode bar assemblies (21) is connected to the negative power source and remaining electrode bar assemblies are connected to the positive power source; and a controller (30) that reads information from the sensor part (20) and commands to output an alarm signal by determining that bubbles are filled up to an upper part of the vacuum container when the electrode bar assemblies (21) become conductive. |
