[Abstract] The utility model relates to a filter, in particular to a filter for a vacuum packaging machine. A filter for a vacuum packaging machine includes a shell, an exhaust pipe joint, an exhaust pipe joint, and a filter core. A sinking cavity formed by a spiral down channel is disposed in the shell, and the upper end of the sinking cavity communicates with the exhaust pipe joint. A relatively large volume decompression chamber is provided at the lower outlet of the chamber, and a decompression chamber is disposed below the filter cartridge. An ascending chamber is provided between the filter cartridge and the decompression chamber. The utility model is provided with a sinking cavity, a decompression cavity and an ascending cavity in the shell. The cavity communicates with each other and is in communication with the filter element. A descending spiral guide plate is arranged on the sinking cavity. The flow rate of the powder-carrying gas entering the shell is reduced, so that the gas and the powder are separated, the powder is not easily brought into the vacuum pump, and the precipitated powder is left in the filter for easy recovery. The filter has a simple structure and is filtered. The effect is good and practical.
