As used herein, the terms “first,” “second,” and “third,” etc., are used interchangeably to distinguish one component from another and are not intended to indicate the location or importance of individual components.

[0047] like Figures 1 to 3 As shown, according to an embodiment of this application, a vacuum machine 10 is provided, which is applied to a Mason flask 21. The vacuum machine 10 includes a body 101, which includes two end faces, namely a first end face 102 and a second end face 103. In an embodiment of this application, the first end face 102 and the second end face 103 are located in opposite directions of the body 101. However, in other embodiments, the first end face 102 and the second end face 103 may be in other directions, and no specific limitation is made here.

[0048] The first end face 102 is provided with an inwardly recessed first vacuum chamber 1021, which includes a first chamber bottom 1022 and a first sealing ring 104. The first chamber bottom 1022 is provided with a first air intake hole 1023. The second end face 103 is provided with an inwardly recessed second vacuum chamber 1031, which includes a second chamber bottom 1032 and a second sealing ring 105. The second chamber bottom 1032 is provided with a second air intake hole 1033.

[0049] The difference between the first vacuum chamber 1021 and the second vacuum chamber 1031 lies in the different specifications of the bottle neck 211 of the Mason flasks 21 that can be contained in the two vacuum chambers. Specifically, the first vacuum chamber 1021 is configured to contain a standard bottle neck for the Mason flask 21, while the second vacuum chamber 1031 is configured to contain a non-standard bottle neck for the Mason flask 21. Figure 5In the illustrated embodiment, the opening radius R2 of the second vacuum chamber 1031 is larger than the opening radius R1 of the first vacuum chamber 1021. The first vacuum chamber 1021, corresponding to R1, can accommodate standard bottle necks, while the second vacuum chamber 1031, corresponding to R2, can accommodate non-standard bottle necks. In this embodiment, the standard bottle neck can be 70mm, commonly used in the industry, and the non-standard bottle neck can be 86mm, also commonly used in the industry. Other sizes can also be chosen; no specific limitations are imposed here. In some embodiments, the first vacuum chamber 1021, corresponding to R1, can accommodate non-standard bottle necks, while the second vacuum chamber 1031, corresponding to R2, can accommodate standard bottle necks; this arrangement is also unrestricted.

[0050] The machine body 101 is equipped with a vacuum assembly 30, which includes a first pipe 3051 and a second pipe 3052. The first end of the first pipe 3051 is connected to the end of the first suction port 1023 facing away from the first vacuum chamber 1021; the first end of the second pipe 3052 is connected to the end of the second suction port 1033 facing away from the second vacuum chamber 1031. The second ends of both the first pipe 3051 and the second pipe 3052 are connected to different inlets of a three-way valve 307, and the outlet of the three-way valve 307 is connected to a vacuum pump 302. The three-way valve 307 is an electrically controlled valve, and both the three-way valve 307 and the vacuum pump 302 are electrically connected to the main control board 301. The main control board 301 can selectively control the connection state of the three-way valve 307 to connect the vacuum pump 302 to either the first suction port 1023 or the second suction port 1033.

[0051] In some embodiments, the main control board 301 is provided with a control switch, and the main control board 301 controls the connection state of the three-way valve 307 and the working state of the vacuum pump 302 according to different states of the control switch. In some embodiments, the main control board 301 can receive the number of times the control switch is touched; for example, the first touch of the control switch starts the vacuum pump 302, and the three-way valve 307 connects the first suction port 1023 to the vacuum pump 302; the second touch of the control switch controls the main control board 301 to control the three-way valve 307 to connect the second suction port 1033 to the vacuum pump 302; the third touch of the control switch stops the vacuum pump 302.

[0052] like Figure 5 As shown, in some embodiments, the main control board 301 is electrically connected to a direction sensing switch 3010, which is mounted on the body 101. The direction sensing switch 3010 can detect changes in the direction of the vacuum machine 10, and the main control board 301 can control the connection state of the three-way valve 307 according to the changes in the direction of the vacuum machine 10. Figure 5As shown, assuming the vacuum pump 10 in the figure is in the first orientation state, the main control board 301 controls the three-way valve 307 to connect the first suction port 1023 to the vacuum pump 302. In this state, the Mason flask 21 can be placed in the first vacuum chamber 1021, and after starting the vacuum pump 302, a vacuum will be drawn from the Mason flask 21. If... Figure 5 When the vacuum pump 10 is flipped up and down, it is in the second orientation state. The main control board 301 controls the three-way valve 307 to connect the second suction port 1033 to the vacuum pump 302. The Mason flask 21 is placed in the second vacuum chamber 1031, and the vacuum is drawn as described above, so it will not be repeated here.

[0053] The vacuuming time can be preset in the main control board 301 or controlled by the user. However, the vacuuming time will vary depending on the filling amount and material of the Mason flask 21. It is difficult to ensure operational quality solely through preset time or user control. Therefore, as... Figure 3 , Figure 7 and Figure 8 As shown, in some embodiments, a three-way valve 307 is connected to the vacuum pump 302. Specifically, the three-way valve 307 and the three-way valve 307 are connected via a third pipe 3053, and the three-way valve 302 is connected via a fourth pipe 3054. The other end of the three-way valve is connected to a vacuum sensor switch 304 via a fifth pipe 3055. The vacuum sensor switch 304 is electrically connected to the main control board 301. When the vacuum pump 302 starts, the main control board 301 can obtain the current negative pressure value of the Mason flask 21 in real time through the vacuum sensor switch 304. The vacuum pump 302 is shut off after the negative pressure value reaches a threshold, and the vacuum extraction is completed. This implementation allows the vacuum machine 10 to control the vacuum extraction time according to the actual situation of the Mason flask 21, improving the quality of operation.

[0054] After vacuum extraction is completed, the vacuum chamber remains in a vacuum state, making it difficult for the Mason flask 21 to detach. Therefore, in some embodiments, the vacuum pump 302 can be a bidirectional pump, capable of both evacuating and pumping air. After vacuum extraction is complete, the vacuum pump 302 can inject air into the vacuum chamber to release the vacuum. In another embodiment, the three-way connector in the above embodiment is replaced with a four-way connector 306. The four-way connector 306 is connected to a normally closed one-way valve 303 via a sixth pipe 3056. The one-way valve 303 is electrically connected to the main control board 301. After vacuum extraction is complete, the one-way valve 303 opens, allowing the vacuum chamber to connect with the outside world and balance the internal and external air pressures, thus releasing the vacuum.

[0055] like Figure 1 and Figure 9As shown, in some embodiments, the body 101 is provided with a panel 308, and the panel 308 is provided with a power switch. The power switch is electrically connected to the main control board 301 and can control the working state of the vacuum machine 10. The above-mentioned working state includes, but is not limited to, controlling the connection state of the three-way valve 307 and the start and stop of the vacuum pump 302 in some embodiments; controlling the start and stop of the vacuum pump 302 in some embodiments; and controlling the pumping / airing state of the vacuum pump 302 in some embodiments.

[0056] In some embodiments, the panel 308 is further provided with at least one indicator light 3082, all of which are electrically connected to the main control board 301. The indicator light 3082 is used to display the operating status of the vacuum machine 10, which includes, but is not limited to, displaying the status of the vacuum pump 302, the status of the one-way valve 303, the status of the vacuum sensor switch 304, and the status of the three-way valve 307, etc.

[0057] In some embodiments, the panel 308 is further provided with a power interface 3083, which is electrically connected to the main control board 301 and is used to connect an external power adapter. The vacuum machine 10 of this application can be powered by an external power source or can have a built-in battery 309. The battery 309 can be a rechargeable battery. The main control board 301 is provided with a power management circuit, which includes a charging circuit. When the vacuum machine 10 is connected to a power adapter, it can charge the rechargeable battery 309.

[0058] like Figures 10 to 12 As shown, Figure 10 A Mason jar 21 is shown with a lid 212 on top. Figure 11 The cap 212 is placed at the mouth 211 of the Mason jar 21, and then the vacuum machine 10 is placed above the Mason jar 21, housing the mouth 211 and cap 212 within the first vacuum chamber 1021. The inlet 1042 of the first sealing ring 104 has a smaller radius than the mouth 211, but the first sealing ring 104 is made of a rubbery material, giving it a certain degree of elasticity. Therefore, even with an interference fit, the mouth 211 and the inlet 1042 of the first sealing ring 104 can still be embedded in the first vacuum chamber 1021, and the sidewall of the mouth 211 is tightly wrapped by the first sealing ring 104, thus creating a relatively sealed environment for the mouth 211 and cap 212. Figure 12 As shown, since there is a gap between the cap 212 and the bottle mouth 211, when the vacuum machine 10 is started, the air in the Mason bottle 21 is drawn into the first vacuum chamber 1021 by the vacuum pump 302 through the gap, and then enters the vacuum pump 302 through the first suction hole 1023 and the three-way valve 307, and is then discharged.

[0059] In some embodiments, such as Figure 6 As shown, the first sealing ring 104 is detachably and movably connected to the first cavity bottom 1022. One purpose of this movable connection is that the material of the first cavity bottom 1022 does not need to be elastic compared to the first sealing ring 104. Therefore, the first cavity bottom 1022 and the first sealing ring 104 can be made of different materials and can be processed independently. The movable connection is one way to combine the two. Secondly, due to wear and material aging, the sealing performance of the first sealing ring 104 on the bottle mouth 211 will gradually decrease. The detachable structure makes the replacement of the first sealing ring 104 easier and more economical. Thirdly, the inlet 1042 radius of the first sealing ring 104 of different sizes can be adapted to bottle mouths 211 of different specifications, so that the vacuum machine 10 of this application can be adapted to Mason flasks 21 of different standards.

[0060] like Figure 6 One of the detachable structures shown includes a first sealing ring 104 having a first connecting end 1041 facing the bottle opening 211 and a second connecting end 1043 facing the first cavity bottom 1022. The inner wall of the first connecting end 1041 has an inwardly protruding annular inlet 1042, which can tightly wrap around the outer side of the bottle opening 211. The first cavity bottom 1022 has an annular interface 1024 extending towards the first sealing ring 104, and the second connecting end 1043 of the first sealing ring 104 is fitted onto the outer side of the annular interface 1024. The inner wall of the second connecting end 1043 of the first sealing ring 104 has a sealing ring 1044, which tightly abuts against the outer wall of the annular interface 1024 to seal the first sealing ring 104 to the first cavity bottom 1022.

[0061] like Figure 3 As shown, for ease of assembly and subsequent maintenance, in some embodiments, the first end face 102 of the body 101 is provided with a detachable cover 106, and the aforementioned first vacuum chamber 1021 is disposed on the cover 106. The body 101 has an open cavity, in which the vacuum assembly 30 is placed. The cover 106 is installed at the opening of the cavity and encapsulates the vacuum assembly 30 within the cavity.

[0062] like Figure 13As shown, the vacuum machine 10 of this application can also be applied to a vacuum storage bag via an adapter 22. The first end of the adapter 22 can be selectively inserted into the second suction port 1033, and the second end of the adapter 22 is connected to the air extraction port of the vacuum storage bag. Starting the vacuum machine 10 will evacuate the vacuum storage bag. The diameters of the first suction port 1023 and the second suction port 1033 can be the same or different, which is not limited here. In this embodiment, the diameters of the first suction port 1023 and the second suction port 1033 are different, allowing for the adaptation of different adapters 22. In some embodiments, the inner walls of the first suction port 1023 and the second suction port 1033 are provided with sealing rings 1034 to improve sealing performance.

[0063] The above descriptions are merely examples of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
