[0002] It is a common method to store food or inject seasoning into food using a vacuum system provided with a container such as a bag or a box and a vacuum device such as a vacuum pump. However, it still takes too much time to complete the injection of seasoning using a conventional vacuum system. Thus, there is a need for improvement. SUMMARY

[0003] It is an object of the present application to provide a seasoning injection system and a vacuum device thereof.

[0004] To achieve the above object, the present application discloses a seasoning injection system. The seasoning injection system comprises a container assembly and a vacuum device. The container assembly comprises a container and a control valve. An accommodation space is formed in the container.

[0007] According to an embodiment of the present application, the control valve passes through the opening, and when the control valve is mounted on the container, part of the control valve is located in the recess.

[0008] According to an embodiment of the present application, a protruding ring is provided on the cover portion and surrounds the outer edge of the recess, and the protruding ring is in sealing contact with a sealing member of the vacuum device.

[0010] According to one embodiment of the present invention, the control valve includes a base, a first cover, and a second cover. The first cover is fixed between the second cover and the base. When the control valve is in the first use position, the first cover and the base are respectively close to the outer and inner sides of the container, and the opening is not completely covered by the first cover located on the outer side of the container, allowing internal gas to flow out of the containment space through the opening and external gas to flow into the containment space through the opening. When the control valve is in the second use position, the first cover and the second cover are respectively close to the inner and outer sides of the container, and the opening is completely covered by the second cover located on the outer side of the container, allowing internal gas to flow out of the containment space through the opening and preventing external gas from flowing into the containment space through the opening.

[0011] According to one embodiment of the present invention, the size of the opening is smaller than the size of the second cover and larger than the size of the first cover.

[0012] According to one embodiment of the present invention, the vacuum device includes a circuit board and a vacuum pump electrically connected to the circuit board. When the vacuum device is in a first operating mode, the circuit board controls the vacuum pump to extract internal gas from the containment space, and then repeatedly stops extracting internal gas from the containment space. When the vacuum device is in a second operating mode, the circuit board controls the vacuum pump to extract internal gas from the containment space, and then stops extracting internal gas from the containment space only once; when the control valve is in the first operating position, the vacuum device is in the first operating mode. When the control valve is in the second operating position, the vacuum device is in the second operating mode.

[0013] According to one embodiment of the present invention, the vacuum device further includes a solenoid valve electrically connected to the circuit board, the circuit board further controlling the opening of the solenoid valve to introduce external gas into the containment space during a period of time when the vacuum pump stops extracting internal gas from the containment space while the vacuum device is in the first operating mode.

[0014] According to one embodiment of the present invention, the vacuum device further includes a one-way valve connected to the suction end of the vacuum pump.

[0015] According to one embodiment of the present invention, the vacuum device further includes a pressure sensor electrically connected to the circuit board and enabling the circuit board to perform pressure control.

[0016] According to one embodiment of the present invention, the vacuum device further includes a timer electrically connected to the circuit board and enabling the circuit board to perform time control.

[0017] According to one embodiment of the present invention, the vacuum device further includes a discharge pipe connected to the discharge end of the vacuum pump.

[0018] According to one embodiment of the invention, the flavoring agent injection system further includes an isolator and a level sensor. The isolator is connected between the vacuum device and the container, and provides an isolation space for containing liquid flowing out of the containing space. The level sensor detects the liquid level within the isolation space.

[0019] According to one embodiment of the present invention, the container is a flexible bag or a rigid box.

[0020] To achieve the above objectives, the present invention also includes a vacuum device for a flavoring agent injection container assembly. The vacuum device includes a circuit board and a vacuum pump electrically connected to the circuit board. In a first operating mode, the circuit board controls the vacuum pump to extract internal gas from a containment space formed within the container assembly, and then repeatedly stops extracting internal gas from the containment space. In a second operating mode, the circuit board controls the vacuum pump to extract internal gas from the containment space formed within the container, and then stops extracting internal gas from the containment space only once.

[0021] According to one embodiment of the present invention, the vacuum device further includes a solenoid valve electrically connected to the circuit board, the circuit board further controlling the opening of the solenoid valve such that when the vacuum device is in a first operating mode, during a period of time when the vacuum pump stops extracting internal gas from the containment space, external gas is introduced into the containment space.

[0022] According to one embodiment of the present invention, the vacuum device further includes a one-way valve connected to the suction end of the vacuum pump.

[0023] According to one embodiment of the present invention, the vacuum device further includes a pressure sensor electrically connected to the circuit board and enabling the circuit board to perform pressure control.

[0024] According to one embodiment of the present invention, the vacuum device further includes a timer electrically connected to the circuit board and enabling the circuit board to perform time control.

[0025] According to one embodiment of the present invention, the vacuum device further includes a discharge pipe connected to the discharge end of the vacuum pump.

[0026] In summary, the vacuum device in this invention can be used in different operating modes for different purposes. When it is necessary to inject seasoning into food, the vacuum device can be switched to the first operating mode to extract the gas in the containment space formed within the container, and then the extraction of gas in the containment space can be stopped, or even external gas can be repeatedly introduced into the containment space to create an oscillating negative pressure environment in the containment space to facilitate the seasoning of the food, i.e., accelerate the injection of seasoning. Furthermore, the vacuum device can also be switched to the second operating mode to create a stable, pressure-free, oscillating negative pressure environment in the containment space for conventional vacuum use.

Therefore, the drawings and descriptions should be considered illustrative rather than restrictive. Furthermore, unless otherwise specified, the term “connection” refers to an indirect or direct electrical / mechanical connection. Thus, if a first device is connected to a second device, the connection can be a direct electrical / mechanical connection or an indirect mechanical connection through other means or connection methods.

[0045] Please see Figures 1 to 3 . Figure 1 This is a schematic diagram of the flavoring agent injection system 1 in the first embodiment of the present invention. Figure 2 This is a schematic diagram of the container assembly 11 of the seasoning injection system 1 in the first embodiment of the present invention. Figure 3 This is an exploded view of the container assembly 11 in the flavoring injection system 1 according to the first embodiment of the present invention. Figures 1 to 3As shown, the flavoring agent injection system 1 includes a container assembly 11 and a vacuum device 12. The container assembly 11 includes a container 111 and a control valve 112. A containing space S is formed within the container 111 for holding food and flavoring substances. An opening O communicating with the containing space S is formed on the container 111. The control valve 112 is detachably mounted on the container 111, allowing unidirectional or bidirectional gas flow through the opening O. The vacuum device 12 is used to extract internal gas, causing it to flow out of the containing space S through the opening O, or to introduce external gas into the containing space S through the opening O.

[0046] Specifically, such as Figure 2 and Figure 3 As shown, the container 111 includes a receiving portion 1112 and a cover portion 1111 detachably mounted on the receiving portion 1112. More specifically, in this embodiment, the container 111 is a rigid box. However, the invention is not limited thereto. The opening O is provided on the cover portion 1111, and the receiving space S is formed between the receiving portion 1112 and the cover portion 1111. Preferably, a recess C is provided on the cover portion 1111, and the opening O is provided on the wall of the recess C. When the control valve 112 is mounted on the container 111, the control valve 112 passes through the opening O and is partially received within the recess C.

[0047] Please see Figures 4 to 7 . Figure 4 This is a schematic diagram of the control valve 112 in the container assembly 11 of the flavoring injection system 1 according to the first embodiment of the present invention. Figure 5 This is a top view of the lid 1111 of the container 111 in the container assembly 11 of the seasoning injection system 1 according to the first embodiment of the present invention. Figure 6 This is a schematic diagram of the seasoning injection system 1 when the control valve 112 is in the first use position P1 in the first embodiment of the present invention. Figure 7 This is a schematic diagram of the seasoning injection system 1 when the control valve 112 is in the second usage position P2 according to the first embodiment of the present invention. The control valve 112 can... Figure 6 The first usage position P1 shown is... Figure 7 The second usage position P2 is shown. Figure 6 As shown, when the control valve 112 is in the first operating position P1, the opening O is not completely covered by the control valve 112, allowing internal gas to flow out of the containing space S through the opening O, and allowing external gas to flow into the containing space S through the opening O, thereby achieving bidirectional gas flow. Figure 7As shown, when the control valve 112 is in the second use position P2, the opening O is completely covered by the control valve 112, allowing internal gas to flow out of the containment space S through the opening O, and preventing external gas from flowing into the containment space S through the opening O, so as to achieve one-way gas flow.

[0048] like Figure 4 As shown, to achieve the above-mentioned functions of the control valve 112, the control valve 112 has an integral structure and is made of an elastic or deformable material. Specifically, the control valve 112 includes a first cover 1121, a second cover 1122, and a base 1123. The first cover 1121 is fixedly connected between the second cover 1122 and the base 1123. More specifically, as... Figure 4 and Figure 5 As shown, one dimension of the base 1123 is larger than one dimension of the first cover 1121 and smaller than one dimension of the second cover 1122; for example, diameter D3 is larger than diameter D1 and smaller than diameter D2. Furthermore, one dimension between the two distal ends of the opening O is smaller than one dimension of the second cover 1122 and larger than one dimension of both the first cover 1121 and the base 1123; for example, distance D0 is smaller than diameter D2 and larger than both diameters D1 and D3. Figure 6 As shown, when the control valve 112 is in the first operating position P1, the first cover 1121 and the base 1123 are close to the outer and inner sides of the container 111, respectively, for example, the outer and inner sides of the wall of the recess C; the opening O is not completely covered by the first cover 1121 located on the outer side of the container 111, nor is it completely covered by the second cover 1122, so as to allow internal gas to flow out of the containing space S through the opening O, and to allow external gas to flow into the containing space S through the opening O. When the control valve 112 is in the second operating position P2, the first cover 1121 and the second cover 1122 are close to the inner and outer sides of the container 111, respectively, and the second cover 1122 located on the outer side of the container 111 completely covers the opening O, while the first cover 1121 does not completely cover the opening O. At this time, the second cover 1122 located outside the container 111 can be elastically lifted by the internal gas extracted by the vacuum device 12, so that the internal gas of the containment space S can flow out through the opening O, and the second cover 1122 can be elastically pressed to the outside of the container 111 by the external gas to close the opening O, thereby preventing external gas from flowing into the containment space S through the opening O.

[0049] Preferably, such as Figure 2 , Figure 3 , Figure 6 andFigure 7 As shown, a protruding ring R is provided on the cover 1111 surrounding the outer edge of the recess C. The protruding ring R engages with the sealing element 120 of the vacuum device 12 in a sealing manner, thereby achieving an airtight connection between the vacuum device 12 and the container 111 when the vacuum device 12 is connected to the container 111, such as the cover 1111 of the container 111. The sealing element 120 may be made of an elastic material, allowing it to elastically deform to allow gas flow to release the airtight connection between the vacuum device 12 and the container 111, thus making it easy to separate the vacuum device 12 from the container 111.

[0050] Please see Figures 8 to 10 . Figure 8 This is a cross-sectional view of the vacuum device 12 in the flavoring injection system 1 of the first embodiment of the present invention. Figure 9 This is an exploded view of the vacuum device 12 in the flavoring injection system 1 of the first embodiment of the present invention. Figure 10 This is a block diagram of the vacuum device 12 in the flavoring injection system 1 according to the first embodiment of the present invention. Figures 8 to 10 As shown, 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 controls the vacuum pump 122 to extract internal gas from the containment space S, and then, when the vacuum device 12 is in a first operating mode, such as a flavoring injection mode, repeatedly stops extracting internal gas from the containment space S. The circuit board 121 further controls the vacuum pump 122 to extract internal gas from the containment space S, and then, when the vacuum device 12 is in a second operating mode, such as a normal mode, stops extracting internal gas from the containment space S only once.

[0051] like Figures 8 to 10 As shown, the vacuum device 12 also includes a solenoid valve 123 electrically connected to the circuit board 121. The circuit board 121 further controls the solenoid valve 123 to open, so that when the vacuum device 12 is in the first operating mode, for a period of time during which the vacuum pump 122 stops extracting internal gas from the containment space S, external gas is introduced into the containment space S. It is understood that the solenoid valve 123 can be replaced with any other pressure regulator.

[0052] Preferably, such as Figure 9 As shown, in order to achieve airflow control, the vacuum device 12 also includes a one-way valve 124 connected to the suction end of the vacuum pump 122 to prevent external gas from flowing into the containment space S through the vacuum pump 122.

[0053] Preferably, such as Figure 9As shown, in order to prevent damage to the internal parts of the vacuum device 12, the vacuum device 12 also includes a discharge pipe 125 connected to the discharge end of the vacuum pump 122 and an outlet E of the vacuum device 12, so as to guide the internal gas that may contain particles and / or moisture directly out of the vacuum device 12, thereby preventing the internal parts of the vacuum device 12 from contacting particles or moisture.

[0054] In addition, such as Figure 9 and Figure 10 As shown, in order for the circuit board 121 to control the pressure, the vacuum device 12 also includes a pressure sensor 126 electrically connected to the circuit board 121 and detecting the pressure of the containment space S.

[0055] In addition, such as Figure 10 As shown, in order for the circuit board 121 to control time, the vacuum device 12 also includes a timer 127 electrically connected to the circuit board 121 and counting in hours, minutes, or seconds. The timer 127 can be set by the user or the manufacturer.

[0056] For example, via the pressure sensor 126 and the timer 127, in one cycle of the first operating mode, the circuit board 121 can turn on the vacuum pump 122 and close the solenoid valve 123 to extract the internal gas from the containment space S, thereby reducing the pressure in the containment space S to a first predetermined pressure, for example -8.5 psi, for 3 minutes. Then, the circuit board 121 can further turn off the vacuum pump 122 and turn on the solenoid valve 123 to introduce external gas into the containment space S, thereby increasing the pressure in the containment space S to a second predetermined pressure, for example -6.5 psi, for 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 containment space S to a third predetermined pressure, for example -6 psi, and then turn off the vacuum pump 122 to stop extracting internal gas.

[0057] It should be noted that, in order to ensure the normal operation of the system, the control valve 112 must be adjusted to the appropriate position according to the working mode of the vacuum device 12.

[0058] like Figure 6 As shown, when the vacuum device 12 needs to be operated in the first working mode, the control valve 112 needs to be located in the first usage position P1, so that the vacuum device 12 in the first working mode extracts internal gas out of the containing space S and introduces external gas into the containing space S, thereby creating an oscillating negative pressure environment in the containing space S, causing the food to expand and compress with the pressure oscillation, which is conducive to food seasoning, that is, accelerating the injection of seasoning.Figure 7 As shown, when the vacuum device 12 needs to be operated in the second working mode, the control valve 112 needs to be set in the second use position P2 so that the vacuum device 12 in the second working mode generates a stable negative pressure environment in the containment space S without pressure oscillation, for conventional vacuum use.

[0059] Please see Figures 11 to 14 . Figure 11 This is a schematic diagram of the flavoring injection system 1' in the second embodiment of the present invention. Figure 12 This is an exploded view of the flavoring injection system 1' according to a second embodiment of the present invention. Figure 13 This is a partial cross-sectional view of the flavoring injection system 1' in the second embodiment of the present invention. Figure 14 This is a partial block diagram of the seasoning injection system 1' in the second embodiment of the present invention. The seasoning injection system 1' in the second embodiment is similar to the seasoning injection system 1 in the first embodiment. Figures 11 to 14 As shown, unlike the first embodiment, in the second embodiment, the container 111' is a flexible bag with a seal, and the flavoring injection system 1' further includes an isolator 13' and a liquid level sensor 14'. The isolator 13' is connected between the vacuum device 12' and the container 111', for example, a detachable connection, and provides an isolation space 131' for accommodating liquid flowing out from the containment space formed within the container 111'. Preferably, the container 111' has a protruding ring R1' that is sealed to the seal 130' of the isolator 13', and a joint R2' that is sealed to the seal 120' of the vacuum device 12'. The liquid level sensor 14' is configured to detect the liquid level within the isolation space 131'. In this embodiment, the liquid level sensor 14' may include a conductor 141' disposed on the isolator 13' and a non-contact liquid level sensor 142' disposed within the vacuum device 12' and connected to the circuit board 121' of the vacuum device 12'. The non-contact liquid level sensor 142' can cooperate with the conductor 141' to detect capacitance changes, enabling the circuit board 121' to control the liquid level and prevent it from entering the vacuum device 12' when the liquid reaches the bottom of the conductor 141'. For example, when the liquid level reaches the bottom of the conductor 141', the circuit board 121' can control the vacuum pump 122' to stop working and / or control the solenoid valve 123' to open, depending on actual needs. Further detailed descriptions of the second embodiment are the same as those of the first embodiment. For simplicity, detailed descriptions are omitted herein.

[0060] Please see Figure 15 and Figure 16 .Figure 15 This is a partial cross-sectional view of the flavoring injection system 1” in the third embodiment of the present invention. Figure 16 This is a partial block diagram of the seasoning injection system 1” in the third embodiment of the present invention. The seasoning injection system 1” in the third embodiment is similar to the seasoning injection system 1' in the second embodiment. Figure 15 and Figure 16 As shown, unlike the second embodiment, in the third embodiment, the liquid level sensor 14” may include a floating element 141” disposed within the isolation space 131” of the isolator 13”. When the liquid in the isolation space 131” increases, the floating element 141” may move closer to the outlet seal 132” of the isolator 13” under the rise of the liquid to block the gas outlet 133” of the isolator 13”. When the floating element 141” blocks the gas outlet 133” of the isolator 13”, the pressure sensor 126” may detect abnormal high pressure, thereby enabling the circuit board 121” to perform liquid level control accordingly. For example, depending on actual needs, the circuit board 121” may control the vacuum pump 122” to stop working and / or control the solenoid valve 123” to open.

[0061] Compared to existing technologies, in this invention, the vacuum device can be used in different operating modes for different purposes. When it is necessary to inject seasoning into food, the vacuum device can be switched to the first operating mode to extract the internal gas in the containment space formed within the container, and then the extraction of the internal gas in the containment space can be stopped. External gas can even be repeatedly introduced into the containment space to create an oscillating negative pressure environment within the containment space, thereby facilitating the seasoning of the food, i.e., accelerating the injection of seasoning. Furthermore, the vacuum device can also be switched to the second operating mode to create a stable, pressure-free, oscillating negative pressure environment in the containment space for conventional vacuum use.

[0062] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept. Therefore, the above-described embodiments merely illustrate several implementations of the present invention and should not be construed as limiting the scope of the invention.
