Refer toto, technical solutions used in this specification implementation are as follows: The easy-to-use vacuuming device includes a main body, a top of the main bodyis provided with a wide-mouth end, a bottom of the main bodyis provided with a standard-mouth end, and an inner diameter of the wide-mouth endis greater than an inner diameter of the standard-mouth end. The main bodyis provided with a first air valveand a second air valve, the first air valveis provided with a first bent pipethat is connected to the wide-mouth end, and the second air valveis provided with a second bent pipethat is connected to the standard-mouth end. The main bodyis further provided with a vacuum detector, and the vacuum detectoris connected to the first gas valve, the second gas valve, and a vacuum pumpthrough a three-way connecting pipe. When a traditional Mason jar/can is vacuumed, a vacuuming connector is usually used to connect a jar/can mouth for vacuuming. However, when a standard mouth and a wide mouth need to be vacuumed separately, the vacuuming connector needs to be disassembled and replaced for use, but connection is easily not tight during installation, which affects the effect. In this embodiment, the standard-mouth end and the wide-mouth end are disposed. After being connected to the vacuuming device, the first air valve controls a communication state of the wide-mouth end, and the second air valve controls a communication state of the standard-mouth end. During use, the wide-mouth end or standard-mouth end only needs to be connected to the jar/can mouth as needed, to quickly perform vacuuming, without the use of a conversion device for vacuuming, which not only facilitates operation, but also prevents air leakage caused by poor connection during disassembly, ensuring the vacuuming effect.

In addition, in this embodiment, the vacuum detector is also disposed to detect a vacuuming state, the vacuum detector is connected to two gas valves through the three-way connecting pipe, and the three-way connecting pipe is also connected to the vacuum pump. When any air valve is working, the vacuum detector detects a vacuuming state, and emits short-interval beeping sounds. When it is detected a pressure value reaches a preset value, the vacuum detector emits long-interval beeping sounds. If air leakage occurs for a period but a value of air leakage does not reach a preset value, a long beeping alarm is sent, so that a use state of the device can be better learned.

More specifically, a top of the first gas valveis provided with a first connecting end, and the first connecting endis provided with a first connecting portthat is connected to the first bent pipe. A top of the second gas valveis provided with a second connecting end, and the second connecting endis provided with a second connecting portthat is connected to the second bent pipe. A T-shaped three-way pipeis connected between the first gas valveand the second gas valve, and a third port of the T-shaped three-way pipeis connected to the three-way connecting pipe. In this embodiment, the three-way pipe is disposed between the two gas valves, the two gas valves are connected to the vacuum pump through the three-way connecting pipe, and only a single gas valve is used for communication during use. To be specific, when the first air valve is opened, the second air valve is closed, when the second air valve is opened, the first air valve is closed, the two air valves are communicated with the wide-mouth end and the standard-mouth end through two bent pipes for vacuuming, and state detection is performed by the vacuum detector.

More specifically, the wide-mouth endis provided with a first fastening end, the first fastening endhas a stepped horn-mouth shape, and steps of the first fastening endare provided with a first soft rubber pad. The standard-mouth endis provided with a second fastening end, the second fastening endis a stepped horn-mouth shape, and steps of the second fastening endare provided with a second soft rubber pad. Due to a specific curvature of the jar/can mouth, the wide-mouth end and the standard-mouth end have the horn-mouth shapes, and the soft rubber pads are disposed as sealing structures, to ensure the vacuuming effect.

More specifically, a center of the first fastening endis provided with a first communication port, the first communication portis connected to the first bent pipe, a center of the second fastening endis provided with a second communication port, and the second communication portis connected to the second bent pipe. Connections among the wide-mouth end, the standard-mouth end, and the air valves are implemented through connections among the two connecting ports and the bent pipes, a non-integrated structure is more easily installed and maintained, and connections are sealed.

More specifically, the main bodyis provided with a wide-mouth start button, a standard-mouth start button, and a charging port. The wide-mouth start button, the standard-mouth start button, and the charging portare all electrically connected to a control mainboard in the main body, the wide-mouth start buttonis corresponding to the first gas valve, and the standard-mouth start buttonis corresponding to the second air valve. During use, working states of the two gas valves are controlled by the start buttons in two positions. The first air valve is opened by pressing the wide-mouth start button, and the second air valve is closed. The second air valve is opened by pressing the standard-mouth start button, and the first air valve is closed. The two air valves are controlled separately, better facilitating use. It should be noted that a charger can be connected to the charging port for power supply during use, and a rechargeable battery is disposed in the main body. The charging port can charge the rechargeable battery, and the main body can be supplied with power through the battery when not plugged in.

A working principle of the present invention: during use, if the wide-mouth Mason jar/can is to be vacuumed, the wide-mouth endis connected to the jar/can mouth, so that the jar/can mouth is pressed into the first fastening endthat is sealed by the first soft rubber pad. The wide-mouth start buttonis pressed to start the first air valve, so that the wide-mouth endcan be vacuumed. When the standard-mouth Mason jar/can needs to be vacuumed, the standard-mouth endis connected to the jar/can, the jar/can mouth is pressed into the second fastening endthat is sealed by the second soft rubber pad, and the standard-mouth endcan be vacuumed by pressing the standard-mouth start button. In addition, the vacuuming state is detected by the vacuum detectorwithout experience, and a current working state of the device can be determined based on a beeping reminder of the vacuum detector.
