[0002] Mason jars are glass jars with threaded metal lids, offering excellent sealing and suitable for storing dry foods or for pickling. Due to the unique design of the jar's opening and lid, their sealing is primarily achieved using specialized Mason jar vacuum sealers.

[0003] Chinese utility model patent CN 221138784U discloses a vacuum sealer suitable for bottles of different sizes. This utility model features a first and second sleeve for fitting Mason jars of varying sizes within a single cavity, allowing both sleeves to share a common space. This enables the fitting of Mason jars of different diameters in a single location, achieving multi-purpose functionality. A single vacuum sealer can be used for both large and small Mason jars. Furthermore, the main body has a connector for an external vacuum tube, located within the first sleeve and integrated with one of the guide holes. While the main body can also be adapted for other vacuum packaging, the connector requires an external vacuum tube and a connecting cap for connecting to a vacuum bag. The external vacuum tube and connecting cap need to be disassembled and stored when not in use, which users often forget or easily lose. Therefore, we provide a multi-functional Mason jar vacuum preservation machine. Utility Model Content

To provide a comprehensive understanding of this utility model, many details are described below; however, those skilled in the art can implement this utility model without these details. Well-known components, methods, and processes will not be described in detail below.

[0019] Example 1

[0020] This embodiment provides a multifunctional Mason jar vacuum preservation machine, see reference. Figure 1 and Figure 2 The system includes a vacuum pump main body 10 and a connecting sleeve 20. The vacuum pump main body includes a vacuum housing 11, which has an exhaust port communicating with the outside. A vacuum pump 12, a battery 13, a solenoid valve 14, and a control circuit board 15 are installed inside the vacuum housing 11. The vacuum pump 12 and the solenoid valve 14 are electrically connected to the control circuit board 15. The vacuum control principle of the vacuum pump 12 is conventional technology in the field and is not the focus of this invention; therefore, it will not be described in detail here.

[0021] Reference Figure 2 and Figure 3 The aforementioned socket 20 has at least two sockets with different inner diameters. This embodiment shows two sockets with different inner diameters. Specifically, a convex opening groove is formed in the lower part of the socket. The upper part of the convex opening groove forms a first socket 21, and the lower part forms a second socket 22. The first socket 21 and the second socket 22 are located on the same central axis. Of course, the two sockets can be detachably assembled by means of a threaded connection.

[0022] Reference Figure 2 and Figure 3 The upper inner wall of the aforementioned sleeve 20 is provided with a first internal connecting thread 201, and the lower inner wall of the sleeve 20 is provided with a second internal connecting thread 202.
