By implementing the utility model, when the current vacuum value is not within the preset vacuum threshold range, the vacuum pump is driven to perform vacuum, and when the current vacuum value is within the preset vacuum threshold range, the vacuum pump is stopped to perform vacuum, thereby shortening the continuous operation time of the vacuum pump and extending the service life of equipment parts;
