A device for detecting bubbles of a vacuum container for manufacturing cosmetic contents, the bubble detection device comprising: a vacuum container installed to remove air from the cosmetic contents and including a space part having a cylindrical shape or a polygonal shape to accommodate the cosmetic contents therein; a stirring device including an electrical motor installed at an upper part of the vacuum container and a stirrer coupled to the electrical motor, in which the electrical motor is operated to operate the stirrer so that air existing in the cosmetic contents in the vacuum container is degassed to outside; a sensor part installed at an upper end of the vacuum container and including two or more electrode bar assemblies and a humidity sensor part, in which the electrode bar assemblies include an electrode bar and an insulator surrounding an exterior of the electrode bar, one of the electrode bar assemblies 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 is connected to the negative power source and remaining electrode bar assemblies are connected to the positive power source, and the humidity sensor part is installed at the upper end of the vacuum container to check a humidity in the vacuum container; a controller that reads information from the sensor part 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 become conductive, and when a conduction signal of the electrode bar assemblies is received while a humidity value measured by the humidity sensor is equal to or higher than a reference value, to disregard the conduction signal and output a state of the humidity value being equal to or higher than the reference value; and an alarm generating part to output an alarm to outside according to the command of the controller so that a worker may appropriately manipulate the vacuum container. a vacuum container installed to remove air from the cosmetic contents and including a space part having a cylindrical shape or a polygonal shape to accommodate the cosmetic contents therein; a stirring device including an electrical motor installed at an upper part of the vacuum container and a stirrer coupled to the electrical motor, in which the electrical motor is operated to operate the stirrer so that air existing in the cosmetic contents in the vacuum container is degassed to outside; a sensor part installed at an upper end of the vacuum container and including two or more electrode bar assemblies and a humidity sensor part, in which the electrode bar assemblies include an electrode bar and an insulator surrounding an exterior of the electrode bar, one of the electrode bar assemblies 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 is connected to the negative power source and remaining electrode bar assemblies are connected to the positive power source, and the humidity sensor part is installed at the upper end of the vacuum container to check a humidity in the vacuum container; a controller that reads information from the sensor part 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 become conductive, and when a conduction signal of the electrode bar assemblies is received while a humidity value measured by the humidity sensor is equal to or higher than a reference value, to disregard the conduction signal and output a state of the humidity value being equal to or higher than the reference value; and an alarm generating part to output an alarm to outside according to the command of the controller so that a worker may appropriately manipulate the vacuum container.
