The control valve 112 can be moved between the first use position P1 of Fig. 6 and the second usage position P2 of Fig. 7. As in Fig. 6, the opening O is not completely covered by the control valve 112, so that the inside air can flow out of the accommodation space S through the opening O and the outside air can flow into the accommodation space S through the opening O to achieve a bidirectional air connection when the control valve 112 is arranged at the first use position P1. As shown in Fig. 7, the opening O is completely covered by the control valve 112 so that the inside air can flow out of the accommodation space S through the opening O and the outside air is prevented from flowing into the accommodation space S through the opening O to achieve unidirectional air communication when the control valve 112 is arranged at the second use position P2.

[0032] In order to achieve the above-mentioned function of the control valve 112, the control valve 112 has, as shown in Fig. 4, has a one-piece construction and is formed from an elastic or deformable material. In particular, the control valve 112 comprises a first cover part 1121, a second cover part 1122, and a base part 1123. The first cover part 1121 is integrally connected between the second cover part 1122 and the base part 1123. In particular, as shown in Fig. 4 and Fig. 5, a dimension such as a diameter D3 of the base part 1123 is larger than a dimension such as a diameter D1 of the first cover part 1121 and smaller than a dimension such as a diameter D2 of the second cover part 1122.

If, as in Fig. 6, the control valve 112 is arranged at the first use position P1, the first lid part 1121 and the base part 1123 are arranged adjacent to an outer side and an inner side of the container 111, such as an outer side and an inner side of the wall of the concave structure C, respectively, and the opening O is not completely covered by the first lid part 1121 resting on the outer side of the container 111 or by the second lid part 1121, in order to allow the inside air to flow out of the accommodation space S through the opening O and to allow the outside air to flow into the accommodation space S through the opening O. When, as shown in Fig. 7, when the control valve 112 is disposed at the second use position P2, the first lid part 1121 and the second lid part 1122 are disposed adjacent to the outside and the inside of the container 111, respectively, and the opening O is completely covered by the second lid part 1122 resting on the outside of the container 111 and not completely covered by the first lid part 1121. At this time, the second lid part 1122 resting on the outside of the container 111 can be elastically lifted by the inside air drawn by the vacuum device 12 to allow the inside air to flow out of the accommodation space S through the opening O, and the second lid part 1122 can be elastically pressed against the outside of the container 111 by the outside air to seal the opening O and prevent the outside air from flowing into the accommodation space S through the opening O.

The sealing component 120 may be formed of an elastic material such that the sealing component 120 can be elastically deformed to allow the air connection to break the airtight engagement of the vacuum device 12 and the container 111 for easy removal of the vacuum device 12 from the container 111.

[0034] The following refers to Fig. 8 to Fig. 10 is referred to. Fig. 8 is a sectional view of the vacuum device 12 of the flavoring system 1 according to the first embodiment of the present invention. Fig. 9 is an exploded view of the vacuum device 12 of the flavoring system 1 according to the first embodiment of the present invention. Fig. 10 is a functional block diagram of the vacuum device 12 of the flavoring system 1 according to the first embodiment of the present invention. As shown in Fig. 8 to Fig. 10, the vacuum device 12 includes a circuit board 121 and a vacuum pump 122 electrically connected to the circuit board 121. The circuit board 121 repeatedly controls the vacuum pump 122 to draw the internal air from the receiving space S and then to stop drawing the internal air from the receiving space S when the vacuum device 12 is in a first operating mode, such as a flavoring mode. The circuit board 121 further controls the vacuum pump 122 once to draw the internal air from the receiving space S and then to stop drawing the internal air from the receiving space when the vacuum device 12 is in a second operating mode, such as a normal mode.

[0035] As in Fig. 8 to Fig. 10, the vacuum device 12 further includes a solenoid valve 123 electrically connected to the circuit board 121, wherein the circuit board 121 controls the solenoid valve 123 to open to introduce the outside air into the receiving space S during a period in which the vacuum pump 122 stops drawing the inside air from the receiving space S when the vacuum device 12 is in the first operating mode. Of course, any other pressure regulator may be used instead of the solenoid valve 123.

[0036] To achieve air flow control, the vacuum device 12 preferably comprises as shown in Fig. 9 further shows a one-way valve 124 which is coupled to a suction end of the vacuum pump 122 in order to prevent the outside air from flowing through the vacuum pump 122 into the receiving space S.

[0037] And to prevent damage to the internal parts of the vacuum device 12, the vacuum device 12 comprises as in Fig. 9 preferably further shows a drain pipe 125 coupled to an output end of the vacuum pump 122 and an outlet opening E of the vacuum device 12 for directing the internal air, which may contain particles and / or moisture, to flow directly out of the vacuum device 12 to prevent internal parts of the vacuum device 12 from being exposed to the particles or moisture.

[0038] To enable pressure control through the circuit board 121, the vacuum device 12 comprises, as shown in Fig. 9 and Fig. 10 further shows a pressure sensor 126 which is electrically connected to the circuit board 121 and is configured to detect a pressure in the receiving space S.

[0040] Using the pressure sensor 126 and the timer 127, the circuit board 121 can, for example, for one cycle in the first operating mode, turn on the vacuum pump 122 and close the solenoid valve 123 to draw the internal air from the receiving space S and thereby reduce the pressure in the receiving space S to a first predetermined pressure, such as -8.5 psi, for a period of three minutes. The circuit board 121 can then turn off the vacuum pump 122 and open the solenoid valve 123 to introduce the external air into the receiving space S and thereby increase the pressure in the receiving space S to a second predetermined pressure, such as -6.5 psi, for a period of 30 seconds. Furthermore, in the second operating mode, the circuit board 121 can turn on the vacuum pump 122 and close the solenoid valve 123 to reduce the pressure in the receiving space S to a third predetermined pressure, such as-6 psi, and then turn off the vacuum pump 122 to stop the internal air from being drawn.

[0041] It should be noted that the control valve 112 must be set to a correct position corresponding to an operating mode of the vacuum device 12 in order to enable correct operation of the system.

[0042] If, as in Fig. 6, if the vacuum device 12 is to be operated in the first operating mode, the control valve 112 must be moved to the first use position P1 so that the vacuum device 12 can create an oscillating negative pressure environment in the receiving space S in the first operating mode by executing the internal air to flow out of the receiving space S and introducing the external air to flow into the receiving space S, so that the food can be expanded and compressed by the pressure oscillation in order to achieve flavoring of the food and in particular to accelerate the flavoring. If, as in Fig. 7, if the vacuum device 12 is to be operated in the second operating mode, the control valve 112 must be moved to the second use position P2 so that the vacuum device 12 can create a stable negative pressure environment without pressure oscillation in the receiving space S for normal vacuum use in the second operating mode.
