The present invention relates to a bubble detection device for a vacuum container for manufacturing cosmetic contents, which can detect bubbles filling a vacuum container through a phenomenon in which electrode bar assemblies are electrically conductive by means of bubbles when the bubbles fill the vacuum container at a certain level or more by providing a plurality of electrode bar assemblies in the vacuum container, wherein the plurality of electrode bar assemblies are provided by a method for connecting a positive power source to one electrode bar assembly and connecting a negative power source to the rest electrode bars or for connecting the negative power source to one electrode bar assembly and connecting the positive power source to the rest of the electrode bars, the bubble detection device comprising: a vacuum container (100); a stirring device (10); a sensor unit (20) provided on one upper end of the vacuum container and having two or more electrode bar assemblies (21), wherein the electrode bar assemblies (21) have electrode bars (21-1) and insulators (21-2) for encasing the outside of the electrode bars (21-1), and a positive power source is connected to one of the electrode bar assemblies (21) and a negative power source is connected to the rest electrode bar assemblies, or the negative power source is connected to one electrode bar assembly and the positive power source is connected to the rest of the electrode bar assemblies; and a control unit (30) for reading information from the sensor unit (20) and commanding an alarm signal to be outputted by determining that the bubbles are filled up to the top of the vacuum container when the electrode bar assemblies (21) are conductive. |
