Description

Technical Field

[0001] The utility model relates to the technical field of exhaust devices, in particular to a vacuum exhaust device. Background Art

[0002] The vacuum exhaust device is a device used to extract the air inside the bulb and create a vacuum environment. During the bulb manufacturing process, the air inside the bulb must first be extracted to ensure that there is no air or impurities inside the bulb. This is to ensure a stable working environment inside the bulb and prevent problems such as oxidation or corrosion inside the bulb. The vacuum exhaust device for bulb production usually consists of a vacuum pump and an exhaust pipe. The vacuum pump is used to extract the air inside the bulb to create a low-pressure environment, and the exhaust pipe is used to exhaust the extracted air out of the bulb to ensure a vacuum environment inside the bulb. By using the vacuum exhaust device for bulb production, the air inside the bulb can be effectively removed to ensure the quality and performance of the bulb.
