Technical Field

[0001] The invention relates to an interaction method between a vacuum base and a sealing box. Background Art

[0002] As people's living standards improve, they pay more attention to the freshness of food. Vacuum storage is very popular because it can truly preserve food freshness, extend its shelf life, and increase its utilization value. Especially when storing perishable foods or pharmaceuticals and biological products with demanding storage conditions, a highly sealed vacuum storage box is often required.

[0003] Currently, the vacuum storage boxes on the market and the devices that evacuate the vacuum storage boxes are unable to sense each other. That is, the vacuum extraction device can only evacuate the vacuum storage box, but cannot determine whether the items in the vacuum storage box need to be preserved in a vacuum. In other words, the vacuum storage box and the vacuum extraction device cannot exchange information, resulting in a single working mode of the vacuum extraction device. Summary of the Invention

[0004] The object of the present invention is to provide an interaction method between a vacuum base and a sealing box, so as to overcome the problem that the existing vacuuming device and the sealing box cannot perform information interaction, resulting in a single working mode of the vacuuming device.

[0005] To achieve one of the above-mentioned objectives, a method for interacting between a vacuum base and a sealed box is provided, wherein the vacuum base and the sealed box can sense each other, and the method for interacting between the vacuum base and the sealed box comprises:

[0010] As an optional technical solution, S102 further includes recording the first item information in the NFC chip of the sealed box.

[0011] As an optional technical solution, S102 further includes extracting a sealed box image from the first image, numbering the sealed box according to the sealed box image, and recording the number in the NFC chip of the sealed box, so that the number is associated with the corresponding first item information.

[0012] As an optional technical solution, S102 further includes recording the number and the corresponding first item information in a storage unit of the vacuum base.

[0013] As an optional technical solution, it also includes:

[0014] S105, opening the sealed box in S104, taking out the items in the sealed box, and putting new items into the same sealed box;

[0015] S106, placing the same sealed box containing new items on the vacuum base to obtain a second image;

[0016] S107, extracting the sealed box image in the second image, obtaining the serial number of the sealed box, and reading the first item information corresponding to the serial number;

[0017] S108, extract the second object image from the second image, output the second object information, and determine whether the type information of the second object information is consistent with the type information in the first object information; if so, proceed to S109; if not, proceed to S110.

[0023] Compared to existing technologies, the present invention proposes a method for interacting with a vacuum base and a sealed box. By inducing communication between the vacuum base and the sealed box, information exchange can be performed, ensuring that items stored within the sealed box are stored in an optimal vacuum environment. Furthermore, the vacuum base and the sealed box continuously sense each other, and when the information about the items stored in the sealed box changes, the vacuum base can be reset to maintain the optimal vacuum environment. This information exchange between the vacuum base and the sealed box helps overcome the problem of existing vacuuming devices being unable to interact with sealed boxes, resulting in a single operating mode for the vacuuming devices.

[0039] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0040] like Figure 1 As shown, an embodiment of the present invention provides a vacuum assembly 100, which includes a vacuum base 10 and a sealing box 20. The vacuum base 10 is used to remove air from an inner cavity of the sealing box 20, so that a vacuum is formed in the inner cavity.

[0041] In a preferred embodiment, the vacuum base 10 and the sealed box 20 are independent of each other and can be sold separately as separate products. In other words, the vacuum base 10 and the sealed box 20 can each be used independently. In other words, the vacuum base 10 can be used to vacuum a variety of other sealed boxes; the sealed box 20 can also be combined with other vacuum bases to achieve the same vacuuming purpose.

[0042] like Figures 1 to 4 As shown, the vacuum base 10 includes a housing 11, with an exhaust structure provided on the top surface of the housing 11. The exhaust structure is interconnected with the inner cavity 110 of the housing 11; the housing 11 is also provided with an external exhaust hole 14, which is connected to the inner cavity 110 and an exhaust pipeline (not shown) of a pump assembly (not shown). Air in the inner cavity 110 is discharged through the external exhaust hole 14 and the exhaust pipeline, forming a vacuum. The external exhaust hole 14 can be provided at any position of the housing 11. In this embodiment, the external exhaust hole 14 is provided on the side of the housing 11, the side surface surrounding the top surface and extending toward the bottom surface 114 of the housing 11, and the top and bottom surfaces 114 are arranged opposite each other.

[0043] It should be noted that the top surface and the bottom surface 114 refer to the state where the vacuum base 10 is placed horizontally. When the vacuum base 10 is placed upright, the top surface may be the front surface facing the user, and the bottom surface 114 may be the rear surface away from the user.

[0044] like Figure 1 As shown, the top surface includes a first surface 111 and a second surface 112 arranged at an angle, and the angle between the first surface 111 and the second surface 112 is between 0-180 degrees. In this embodiment, the angle between the first surface 111 and the second surface 112 is an obtuse angle, that is, the second surface 112 extends obliquely upward from a side edge of the first surface 111.

[0045] like Figure 1 、 Figure 3 and Figure 4 As shown, an air extraction structure is provided on the first surface 111 , and the air extraction structure is provided in the middle area of ​​the first surface 111 . Even if the sealing box 20 is placed with deviation on the first surface 111 , the vacuuming effect of the vacuum base 10 will not be affected.

[0046] The exhaust structure includes a recessed portion 15 formed on the first surface 111, a cap 12 and a sealing gasket 13. The cap 12 and the sealing gasket 13 are both located in the recessed portion 15. The cap 12 has an extension portion 121. The sealing gasket 13 has an opening facing the extension portion 121, and a step portion 131 is provided in the opening. The card groove of the sealing gasket 13 is engaged with the side wall of the recessed portion 15. The cap 12 is inserted into the opening of the sealing gasket 13, and the extension portion 121 and the step portion 131 are in contact with each other, preferably elastically abutting to prevent the cap 12 from falling off from the opening of the sealing gasket 13.

[0047] The sealing gasket 13 is further provided with a through hole 132 , which is located at the bottom of the sealing gasket 13 , opposite to the opening, and protrudes toward the inner cavity 110 of the shell 11 , wherein the through hole 132 is connected to the inner cavity 110 , and the inner cavity 110 is connected to the external air extraction hole 14 .

[0048] like Figure 3 and Figure 4 As shown, a plurality of mutually spaced extension portions 121 extend from the cap 12 , and gaps 122 are formed between the mutually spaced extension portions 121 . In other words, the cap 12 has gaps 122 .

[0049] In a preferred embodiment, the top surface of the cap 12 protrudes from the top surface of the sealing gasket 13. Preferably, the top surface of the cap 12 is slightly higher than or flush with the first surface 111. The top surface of the cap 12 protrudes from the top surface of the sealing gasket 13, so that the gap 122 has a portion protruding from the top surface of the sealing gasket 13, which facilitates air flow from the gap 122 to the through hole 132.

[0050] In addition, there is a gap between the edge of the cap 12 and the inner side surface of the first recess 115, so that when vacuuming, air can pass through the gap 122, the through hole 132, the inner cavity 110 and the external exhaust hole 14 and be extracted by the pump assembly.

[0051] In a preferred embodiment, the cap 12 and the sealing gasket 13 are both made of elastic materials such as silicone, rubber, etc.

[0052] like Figure 1 and Figure 3 As shown, the first surface 111 and the second surface 112 are set at an obtuse angle, for example, and an identification unit 13 is set on the side of the second surface 112 facing the first surface 111. The identification unit 13 is used to identify items stored in the sealed box 20 to be vacuumed and placed on the first surface 111.

[0053] In this embodiment, the angle between the first surface 111 and the second surface 112 is an obtuse angle, and the identification unit 13 is provided on the side of the second surface 112 facing the first surface 111, so that the identification unit 13 is always facing the sealed box 20 placed on the first surface 111, that is, as long as the sealed box 20 is placed on the first surface 111, the identification unit 13 can smoothly obtain the items and related information stored in the sealed box 20.

[0054] It should be noted that when the identification unit 13 obtains the items stored in the sealed box 20 and related information, the sealed box 20 is, for example, a transparent box body, and the outer packaging of the items in the sealed box 20 is, for example, removed.

[0055] In a preferred embodiment, the identification unit 13 is, for example, a camera module, which includes a camera and an image processing unit. The camera captures an image of the sealed box 20, and the image processing unit obtains the image and extracts the image of the object in the image. The vacuum base 10 also includes a control unit, which is electrically connected to the camera module. After obtaining the image of the object, the control unit compares it with the object information table in the storage unit of the vacuum base 10 to obtain object information, and determines whether the object in the sealed box 20 can be vacuum preserved based on the object information. The control unit controls the vacuum base 10 to output voice and text prompts to inform the user of the object information and whether it is suitable for vacuum preservation.

[0056] In addition, the vacuum base 10 may also include a wireless or wired communication module, that is, the vacuum base 10 can be connected to the internet or cloud via a data cable or Wi-Fi. For example, if the recognition unit 13 is a camera module, the camera captures an image of the sealed box 20, the image processing unit acquires the image and extracts the image of the item in the image, and the control unit compares it with the item information table in the storage unit. If no information similar to the item image is found in the item information table, the control unit activates the wireless or wired communication module to query the network for information on an item identical to the item in the item image, and determines whether the corresponding item can be vacuum preserved. The control unit then controls the voice unit or display unit of the vacuum base 10 to output voice or text prompts to inform the user of the item information and whether it is suitable for vacuum preservation.

[0057] Of course, if the control unit determines that the items in the sealed box (such as fresh vegetables, fresh fruits, etc.) are not suitable for vacuum preservation, the control unit controls the voice unit or the display unit to output voice, text or a combination thereof to prompt the user, and further outputs a control signal to control the vacuum pump component to be in a non-startable state.

[0058] If the control unit determines that the items in the sealed box (such as meat, dairy products, etc.) are suitable for vacuum preservation, the control unit outputs voice, text or a combination thereof to prompt the user. Furthermore, the control unit outputs a control signal to control the vacuum pump component to be in a startable state. When the pump component is started, the sealed box 20 can be vacuumed through the vacuum base 10.

[0059] In addition, based on the image captured by the recognition unit 13, the control unit obtains the item information including: item name, item category (raw food, cooked food, medicine, etc.), vacuum degree required for storage, storage period, storage temperature (low temperature storage, room temperature storage, etc.), etc.

[0060] In one embodiment of the present invention, this item information can be printed onto an item label using a printing device, which the user then affixes to the sealed box 20. The printing device can be integrated into the vacuum base 10, or the vacuum base 10 can be connected to an external printer for printing. The item label can be, for example, a paper label, but is not limited thereto.

[0061] In another embodiment of the present invention, this item information can be transmitted to the NFC chip in the sealed box 20 via the NFC chip in the vacuum base 10. That is, the item information can be stored in the NFC chip in the sealed box 20. When the sealed box 20 is placed in a household appliance, such as a refrigerator, the NFC chip in the sealed box 20 can continue to interact with the NFC chip in the household appliance, facilitating the household appliance's management of the sealed box. In other words, the vacuum assembly 100 provided by the present invention interacts with the sealed box 20 via the vacuum base 10, using the sealed box 20 as a carrier of item information and continuing to interact with the household appliance, making the application of the vacuum assembly 100 more intelligent and improving the user experience.

[0062] In a preferred embodiment, the vacuum base 10 further includes a reset button. When the items stored in the same sealed box 20 are replaced, the reset button is turned on to re-identify the items in the sealed box 20 and update the new item information.

[0063] It should be noted that after the camera of the identification unit 13 of the vacuum base 10 captures the image information of the sealed box and the item, the image processing unit can also obtain the sealed box image, the control unit obtains the sealed box image, and numbers the sealed box 20 currently placed on the vacuum base 10. The number can be printed out through the item label, or transmitted through the NFC chip of the vacuum base 10 and recorded in the NFC chip of the sealed box 20, and the number is associated with the corresponding item information.

[0064] like Figure 14 As shown, in another embodiment of the present invention, a method for interacting between the vacuum base 10 and the sealing box 20 is provided, including:

[0065] S101, acquiring a first image of the sealed box;

[0066] S102, extracting a first object image from the first image and outputting first object information;

[0067] S103, based on the first item information, it is determined whether the item needs to be stored in a vacuum, and if so, proceeds to S104;

[0068] S104: Based on the preset vacuum level in the first article information, the sealed box is evacuated by a pump assembly according to the preset vacuum level.

[0069] In a preferred embodiment, S102 further includes recording the item information into the NFC chip of the sealed box.

[0070] In a preferred embodiment, S102 further includes extracting a sealed box image from the first image, numbering the sealed box according to the sealed box image, and recording the number in the NFC chip of the sealed box, so that the number is associated with the corresponding first item information.

[0071] In a preferred embodiment, S102 further includes recording the serial number and the corresponding first item information in a storage unit of the vacuum base.

[0072] In a preferred embodiment, it also includes:

[0073] S105, opening the sealed box in S104, taking out the items in the sealed box, and putting new items into the same sealed box;

[0074] S106, placing the same sealed box containing new items on the vacuum base to obtain a second image;

[0075] S107, extracting the image of the sealed box in the second image, obtaining the serial number of the sealed box, and reading the first item information corresponding to the serial number;

[0076] S108, extracting the second object image from the second image, outputting the second object information, and determining whether the type information of the second object information is consistent with the type information of the first object information; if so, proceeding to S109; if not, proceeding to S110;

[0077] S109 , comparing the difference information between the second item information and the first item information, and updating the difference information to the NFC chip of the sealed box, or directly recording the second item information to the NFC chip of the sealed box to cover the first item information.

[0078] S110 , resetting the vacuum base 10 so that the vacuum base re-executes the operations in S101 to S104 ; and recording the second item information into the NFC chip of the sealed box to cover the first item information.

[0079] The serial number is associated with the second item information.

[0080] Furthermore, the method includes updating the second item information in the storage unit.

[0081] In addition, the method of the sealed box 20 in the present invention for interacting with a household appliance using the NFC chip storing item information will be described in detail in the method of interacting with a vacuum component and a refrigerator in the present invention.

[0082] In a preferred embodiment, after obtaining the item information, the control unit of the vacuum base 10 can control the vacuum level within the sealed box 20 drawn by the pump assembly, such as a low vacuum state, a high vacuum state, etc., based on the required vacuum level information stored in the item information. In this embodiment, the vacuum level can be read from a pressure gauge on the pump assembly.

[0083] In a preferred embodiment, the vacuum base 10 also includes a time module, and the time module can communicate with the control unit. When the recognition module 13 takes a picture of the items in the sealed box 20 and the control unit determines that the items are suitable for vacuum storage, the sealed box 20 is evacuated and the time module is started to record the initial storage date, which facilitates subsequent users to judge the shelf life of the items in the sealed box 20.

[0084] When the vacuum base 10 outputs the paper label, the initial shelf life date and the maximum shelf life date may be printed on a page of the paper label and attached to the outside of the sealed box 20 .

[0085] When the item information obtained by the vacuum base 10 is transmitted through the NFC chip and recorded in the NFC chip in the sealed box 20 , the initial storage date and the maximum storage date are recorded in the NFC chip in the sealed box 20 along with other item information.

[0086] In a preferred embodiment, the sealed box 20 includes a display unit, which is electrically connected to the NFC chip. The item information recorded in the NFC chip can be displayed on the display unit, so that the user can understand the item information more intuitively.

[0087] In a preferred embodiment, the vacuum base 10 further includes a weighing module, which can be used to weigh the weight of items stored in the sealed box 20. The weighing method includes but is not limited to placing the sealed box 20 on the first surface 111, zeroing, placing items into the sealed box 20, and weighing the weight of the placed items.

[0088] In a preferred embodiment, the vacuum base 10 further includes a voice module. In a first prompt mode, the voice module only outputs usage information for the vacuum base 10; in a second prompt mode, the voice module only outputs usage information for the sealing cartridge 20. The first prompt mode refers to various usage states when the vacuum base 10 is not in place; the second prompt mode displays usage information for the sealing cartridge 20 after the sealing cartridge 20 is in place.

[0089] like Figure 1 、 Figure 2 and Figure 4 As shown, a gravity sensor (not shown) is provided in the vacuum base 10. The gravity sensor is used to sense the placement state of the vacuum base 10. The placement state of the vacuum base 10 includes at least horizontal placement and upright placement. When placed horizontally, the bottom surface 114 contacts the placement platform; when placed upright, any side surface between the bottom surface 114 and the top surface can contact the placement platform.

[0090] In this embodiment, the first side surface 113 is located on a side of the first surface 111 away from the second surface 113 and is connected to a side of the bottom surface 114. Anti-slip pads 16 are provided on the bottom surface 114 and the first side surface 113. The anti-slip pads 16 can be used to prevent the vacuum base 10 from shaking when placed horizontally or upright.

[0091] In a preferred embodiment, the gravity sensor and the control unit are electrically connected (or data transmission is possible). After the gravity sensor senses the position state of the vacuum base, the control unit obtains the corresponding position state and controls the corresponding functional module to start.

[0092] Specifically, when the gravity sensor detects that the vacuum base 10 is in a first placement state, such as a horizontal placement state, the control unit controls the vacuum base 10 to enter a first usage mode, including an identification mode and / or a vacuuming mode. The control unit also uses the voice module to inform the user of the currently available functions of the vacuum base 10 and the specific operating procedures for these functions. Furthermore, when the sealed box 20 is placed on the first surface 111 of the top surface of the vacuum base 10, the voice module can output voice information related to the usage status of the sealed box 20.

[0093] The gravity sensor senses that the vacuum base 10 is in a second placement state, such as an upright placement state, and the control unit controls the vacuum base 10 to enter a second usage mode, such as a timing mode, and turns off the vacuuming mode. In the timing mode, the user can be prompted with the current date through the voice module.

[0094] In addition, when the vacuum base 10 is placed upright, it can save space and is easy to store.

[0095] like Figures 3 and 4 As shown, the housing 11 of the vacuum base 10 further includes a second side surface 115. One side edge of the second side surface 115 connects to the side edge of the second surface 112 away from the first surface 111, and the second side surface 115 is connected to the bottom surface 114 via an arc. In this embodiment, a touch screen display can be provided on the second side surface 115. The touch screen display can display text prompts output by the control unit.

[0096] like Figure 1 、 Figures 5 to 11As shown, the sealing box 20 includes an upper cover 21, a sealing assembly, a box body 25 and a gasket 26 stacked from top to bottom, the sealing assembly includes an upper partition 22, a lower partition 23 and a sealing ring 24 around the periphery of the upper partition 22, and the sealing assembly seals the opening 258 of the box body 25; a first opening 221 and a second opening 229 are provided on the upper partition 22 of the sealing assembly, and the second opening 229 is communicated with the internal storage space of the box body 25; an exhaust port 2531 is provided on the bottom plate 254 of the box body 25; the first opening 221 and the exhaust port 2531 are respectively communicated with the exhaust channel 253; wherein, when the sealing box 20 is placed on the vacuum base 10, the air in the storage space inside the sealing box 20 flows out from the second opening 229, enters the vacuum base 10 from the first opening 221, the exhaust channel 253 and the exhaust port 2531, and is then removed by the pump assembly.

[0097] like Figures 6 to 11 As shown, the upper cover 21 includes a cover body 211 and a first side wall 212 surrounding the cover body 211. The first side wall 212 extends toward the sealing assembly and covers the portion of the sealing assembly protruding from the top end surface 257 of the box body 25. In other words, when the upper cover 21 is placed on the box body 25, the end of the first side wall 212 away from the cover body 211 contacts a portion of the top end surface 257 of the box body 25.

[0098] In this embodiment, the end of the first side wall 212 away from the cover body 211 forms a first coupling portion 2121 . The first coupling portion 2121 is an inverted L-shaped structure that covers the raised portion 241 of the sealing ring 24 and contacts a portion of the top surface 257 .

[0099] A deflation button 27 is provided on the upper side of the lid body 211. This button 27 also includes a first sealing column 272, one end of which is fixedly connected to the deflation button 27. A deflation hole 271 extends through the lid body 211. When the deflation button 27 is closed, the first sealing column 272 on the button 27 fills the deflation hole 271. The lower side of the lid body 211 faces the upper partition 22.

[0100] In this embodiment, the first sealing column 272 is preferably made of soft or elastic materials, such as silicone, rubber, etc. When the first sealing column 272 is inserted into the air vent 271, it can maintain better sealing with the air vent 271, and will not leak during the vacuum process, and the sealing is good.

[0101] In a preferred embodiment, the deflation button 27 is rotatably connected to the cover body 211 via a rotating portion 273. The rotating portion 273 and the first sealing column 272 are respectively located on the side of the deflation button 27 facing the upper partition 22 and are distributed at opposite ends of the deflation button 27. The rotating portion 273 is, for example, a conical protrusion.

[0102] In a preferred embodiment, the cover body 211 is provided with a plurality of positioning protrusions 214 on the side facing the upper partition 22. These protrusions 214 protrude toward the upper partition 22 and penetrate into positioning recesses 225 in the upper partition 22, facilitating alignment and assembly of the upper cover 21 and the sealing assembly. Furthermore, the positioning protrusions 214 penetrate into the positioning recesses 225 and, together with the filling columns 228 therein, seal the positioning recesses 225, preventing air leakage. Specifically, these protrusions 214 prevent air from flowing in or out of the positioning recesses 225.

[0103] In a preferred embodiment, a receiving hole 213 is further provided on the cover body 211 , and the sealing button 28 coupled to the upper side of the upper partition 22 is received in the receiving hole 213 and exposed from the receiving hole 213 , making it convenient for the user to open or close the sealing button 28 .

[0104] like Figures 6 to 11 As shown, in the sealing assembly, a sealing ring 24 is disposed around the upper partition 22, which is provided with a second recess 222. A sealing button 28 is rotatably mounted in the second recess 222. The sealing button 28 includes a second sealing post 281, and a second opening 229 is located in the second recess 22. When the sealing button 28 is in a closed state, the second sealing post 281 is inserted into the second opening 229. When the sealing button 28 is in an open state, the second sealing post 281 is withdrawn from the second opening 229, releasing the vacuum and facilitating removal of the upper cover 21 and the sealing assembly from the opening 258 at the top of the box body 25.

[0105] like Figure 8 and Figure 9 As shown, the sealing button 28 also includes a rotating arm 282 and a rotating shaft 283. The rotating shaft 283 is fixed in the second recess 222. The rotating arm 282 is connected to the rotating shaft 283, so that the sealing button 28 rotates around the rotating arm 283, and then the second sealing column 281 is inserted into or removed from the second opening 229.

[0106] like Figure 6 、 Figure 8 and Figure 9 As shown, the upper partition 22 further includes a second sidewall 223 protruding toward the lower partition 24. A groove 224 is formed on the outer surface of the second sidewall 223, and the sealing ring 24 is embedded in the groove 224. In addition, a plurality of engaging protrusions 226 are formed on the inner surface of the second sidewall 223. The edge of the lower partition 23 protrudes toward the upper partition 22 with an engaging groove 232. The engaging groove 232 engages with the engaging protrusion 226, so that the lower partition 23 and the second sidewall 223 of the upper partition 22 are mutually engaged and connected.

[0107] In this embodiment, the periphery of the lower partition 23 contacts the inner side surface of the second sidewall 223 .

[0108] like Figures 7 to 9 As shown, the side of the sealing ring 24 facing the box body 25 includes a protrusion 241 , and the protrusion 241 is embedded in the upper end of the air extraction channel 253 .

[0109] Corresponding to the protrusion 241 , a first avoidance portion 227 is provided on the upper partition 22 , and a second avoidance portion 233 is provided on the lower partition 23 . The protrusion 241 passes through the first avoidance portion 227 and the second avoidance portion 233 and is stuck in the upper end of the exhaust channel 253 .

[0110] A third opening 242 is defined in the protruding portion 241 , and the third opening 242 is communicated with the first opening 221 .

[0111] In addition, there is a spacing space 243 between the top end of the third opening 242 and the bottom end of the first opening 221, wherein the bottom end of the first opening 221 of the upper partition 22 extends and enters the spacing space 243. On the premise of maintaining the interconnection between the first opening 221, the protrusion 241 and the exhaust channel 253, it can also ensure that when vacuuming, better sealing performance can be maintained between the upper partition 22, the sealing ring 24 and the exhaust channel 253 to avoid air leakage.

[0112] like Figure 6 and Figure 7 As shown, the lower partition 23 includes a plurality of cutouts 231 , and the plurality of cutouts 231 penetrate the lower partition 23 , thereby enabling the storage space in the box body 25 to communicate with the second opening 229 on the upper partition 22 .

[0113] like Figures 6 to 9 As shown, the air extraction channel 253 is located in the storage space of the box body 25 , and the tube wall 252 of the air extraction channel 253 is connected to the inner wall surface 251 of the box body 25 . The tube wall 252 is roughly a U-shaped structure, and the opening of the U-shaped structure faces the inner wall surface 251 .

[0114] It should be noted that the shape of the tube wall is not limited to U-shape or C-shape.

[0115] In this embodiment, the space between the tube wall 252 and the inner wall surface 251 is an air extraction channel 253 .

[0116] Preferably, the top of the exhaust channel 253 engages with the raised portion 241 of the sealing ring 24; the bottom outlet of the exhaust channel 253 is the exhaust port 2531. The bottom outlet of the exhaust channel 253 extends and passes through the bottom plate 254 of the box body 25, so that the exhaust port 2531 passes through the bottom plate 254.

[0117] like Figures 7 to 9As shown, the bottom plate 254 of the box body 25 protrudes a mounting groove 255 toward the gasket 26, and the mounting groove 255 is arranged around the periphery of the bottom plate 254. The gasket 26 includes an upper protrusion 261 and a lower gasket 262. The upper protrusion 261 is embedded in the mounting groove 255 to assemble the gasket 26 and the box body 25. The lower gasket 262 contacts the first surface 111 of the vacuum base 10, wherein the lower gasket 262 extends toward the outer edge of the gasket 26, thereby being better adsorbed on the first surface 111, maintaining the sealing state between the gasket 262 and the bottom plate 254, that is, ensuring the vacuum degree between the sealing box 20 and the vacuum base 10.

[0118] In this embodiment, the washer 26 is adapted to the shape of the bottom plate 254, and is, for example, rectangular, but not limited thereto. In other embodiments of the present invention, the washer may also be in other shapes such as circular, elliptical, polygonal, or the like.

[0119] In addition, the gasket 26 is preferably made of soft or elastic materials such as silicone, rubber, etc., so as to improve the sealing reliability when it contacts the vacuum base 10 .

[0120] The following will be combined with the accompanying drawings Figures 1 to 11 The flow path of gas during the vacuuming process of the vacuum assembly 100 is described.

[0121] The sealed box 20 is placed on the first surface 111 of the vacuum base 10, with the sealing button 28 and the deflation button 27 in the closed state. The pump assembly is turned on, generating negative pressure, causing the air in the storage space within the box body 25 to flow out of the slots 231 and the second opening 229, enter the exhaust channel 253 through the first opening 221 and the third opening 242, and be discharged from the exhaust port 2531 into the gap 122 in the first surface 111 of the vacuum base 10, pass through the through hole 132 and the inner cavity 110, and finally be discharged from the external exhaust hole 14, thereby achieving vacuumization of the sealed box 20.

[0122] like Figure 10 and Figure 11 As shown, after the pump assembly is activated, it generates a strong suction force, which attracts the second sealing post 281 of the sealing button 28 inserted into the second opening 229 and slightly lifts it, creating a small gap, allowing airflow from the storage space of the box body 25 to flow outward. In other words, after the pump assembly is activated, the second opening 229 and the sealing button 28 form a one-way valve.

[0123] After the vacuuming is completed, the pump assembly stops working, and the second sealing column 281 is removed due to the suction effect. The second sealing column 281 is reinserted into the second opening 229 to re-seal the box body 25.

[0124] In addition, when the sealed box needs to be removed from the first surface 111, at this time, the vent button 27 is opened, and the first sealing column 272 is pulled out from the vent port 271. The air enters between the cover body 211 and the upper partition 22 of the upper cover 21 from the vent port 271, and then enters the space between the bottom plate 254 of the box body 25 and the first surface 111 from the first opening 221, the third opening 242, the exhaust channel 253 and the exhaust port 2531. The vacuum adsorption between the bottom plate 254 and the first surface 111 is removed, and the sealed box 20 can be smoothly removed from the first surface 111.

[0125] Since the sealing button 28 is integrated into the second opening 229 , the process of exhausting and releasing the sealing box 20 will not affect the vacuum degree of the box body 25 , so that the sealing box 20 has the advantage of being less prone to air leakage.

[0126] In a preferred embodiment, the sealed box 20 also includes a filter membrane (not shown), which is arranged at the bottom end of the second opening 229 and is used to filter water vapor and oxygen in the air in the box body 25. That is, water vapor and oxygen can pass through the filter membrane and be extracted by the pump assembly, but the nitrogen and inert gas in the air are retained in the storage space in the box body 25, ensuring that the items stored in the box body 25 are in a nitrogen and inert gas environment, which is beneficial to extending the shelf life of the sealed box 20.

[0127] In addition, for special items that need to be stored in an environment with a certain humidity, the filter membrane can allow other gas molecules except water vapor to pass through. When the pump assembly is vacuumed, the water vapor stays in the storage space of the box body 25 to maintain a suitable humidity environment.

[0128] In addition, the filter membrane can also be set at the opening 258 of the box body 25, which is close to the lower side of the lower partition 23. Preferably, the filter membrane covers the entire surface of the opening 258.

[0129] The present invention also provides an interaction method between a vacuum assembly and a household appliance, in particular, an interaction method between a sealed box of a vacuum assembly and a household appliance, wherein the household appliance is, for example, a refrigerator, preferably a smart refrigerator; it can obtain item information by sensing at least one of the vacuum base 10 and the sealed box 20 of the vacuum assembly 100, and intelligently manage items stored in the refrigerator based on the corresponding item information.

[0130] In the present invention, the articles stored in the sealed box 20 include but are not limited to food, medicine, etc.

[0131] like Figure 12As shown, the vacuum assembly 100 includes a vacuum base 10 and a sealed box 20 that are inductively coupled to each other. The vacuum base 10 includes a first sensing unit 30; the sealed box 20 includes a second sensing unit 40, and the sealed box 20 is used to store items; the refrigerator 200 includes a third sensing unit 50; preferably, the first sensing unit 30 and the second sensing unit 40 are inductively coupled to each other; the second sensing unit 40 and the third sensing unit 50 are inductively coupled to each other; that is, the vacuum base 10 and the sealed box 20 interact, and the sealed box 20 and the refrigerator 200 interact.

[0132] like Figure 13 As shown, the interaction method 300 between the vacuum assembly 100 and the refrigerator 200 includes:

[0133] S1, obtain the image of the sealed box and perform the pre-judgment operation;

[0134] S2, the pre-judgment operation includes judging whether the items stored in the sealed box need to be stored at low temperature based on the item information; if so, proceeding to S3;

[0135] S3, outputting a prompt that the sealed box can be stored in a compartment of a refrigerator; and

[0136] S4, place the sealed box in the refrigerator compartment.

[0137] In a preferred embodiment, the operation of acquiring the image of the sealed box in S1 includes:

[0138] placing the sealed box on the first surface of the vacuum base;

[0139] The recognition unit captures an image of the sealed box;

[0140] Extract the object image from the image, compare the object image with the object information table, and obtain the corresponding object information.

[0141] In a preferred embodiment, S3 further includes recording the item information in the second sensing unit of the sealed box.

[0142] In another preferred embodiment, S1 further includes: extracting an image of the sealed box from the image and numbering the sealed box based on the sealed box image; and S3 further includes: recording the number into the second sensing unit, thereby associating the number with the item information. This association of the number and item information facilitates subsequent identification and corresponding update of the item information in the sealed box by the third sensing unit of the refrigerator after it is subsequently updated.

[0143] Among them, the number of the sealed box is associated with the item information. If the item stored in the same sealed box is used or removed later, the item information in the sealed box is updated. At this time, only the item information recorded under the current number needs to be updated, and there is no need to change the number.

[0144] In addition, by associating the number of the sealed box with the item information of the items stored in the sealed box, the sealed box and the household appliance (such as a refrigerator) can help the refrigerator manage and track the sealed boxes stored in its compartment. That is, by establishing an association list of numbers and item information, when the item information recorded under the same number is updated, the item information corresponding to the same number in the association list can be updated in time, which facilitates subsequent management and tracking.

[0145] In another preferred embodiment, S3 further includes:

[0146] According to the item information, determine whether vacuum preservation is required; if so, proceed to S31; if not, proceed to S4;

[0147] In S31, based on the item information, a preset vacuum degree required for storing the item is obtained, and the pump assembly is controlled to evacuate the sealed box according to the preset vacuum degree.

[0148] In addition, S1 or S3 further includes: obtaining weight information of the article in the sealed box and recording the weight information in the second sensing unit, wherein the weight information is one type of article information.

[0149] In this embodiment, the operations in S1 to S3 are all completed in the vacuum base 10 .

[0150] The interaction method 300 of the vacuum assembly 100 and the refrigerator 200 of the present invention further includes:

[0151] S5, controlling the third sensing unit to sense the second sensing unit, so that the refrigerator obtains the item information and number recorded in the second sensing unit of the sealed box;

[0152] S6, obtaining the position information of the sealed box in the refrigerator; and

[0153] S7, based on the location information, obtain the actual temperature of the sealed box where the compartment, determine whether the actual temperature is consistent with the preset storage temperature in the item information; if not, proceed to S8;

[0154] S8, adjusting the actual temperature of the compartment to be consistent with the preset storage temperature, or prompting the user to re-place the sealed box to another compartment where the actual temperature is consistent with the preset storage temperature for storage.

[0155] In this embodiment, the position sensor 60 is disposed in a compartment of the refrigerator. Preferably, the position sensor 60 is located on a different shelf or drawer. The position sensor 60 senses the second sensing unit 40 of the sealed box 20 to obtain position information. The position information includes, for example, the number of the shelf on which the corresponding compartment is located. The position information is recorded in the processing module of the refrigerator.

[0156] Furthermore, location information is linked to the sealed box's serial number. If a sealed box with the same serial number changes position, the box's second sensor re-sensed the location sensor, generating new location information that was then uploaded to the refrigerator's processing module. Recording this location information helps users find their desired items more quickly. Specifically, users input the item they want to remove on the refrigerator's touchpad, and the processing module automatically tracks the location information and prompts them to locate the sealed box where the item is stored, saving time.

[0157] In a preferred embodiment, S7 further includes: adjusting the actual humidity in the refrigerator compartment to be consistent with the preset humidity information according to the preset humidity information in the item information. The actual humidity in the compartment can be measured by a humidity sensor disposed in the compartment.

[0158] In addition, when the actual humidity in the current compartment differs greatly from the preset humidity information, the user is prompted to relocate the sealed box to another compartment where the actual humidity is consistent with the preset storage temperature for storage.

[0159] In this embodiment, the item information includes, but is not limited to, item name, item category, item weight, item storage temperature, item storage vacuum level, item storage ambient humidity, item storage period (including start date and end date), and other information.

[0160] In this embodiment, the first sensing unit 30 , the second sensing unit 40 , and the third sensing unit 50 are NFC chips respectively.

[0161] In one embodiment of the present invention, the item information recorded in the second sensing unit 40 can be temporarily stored in the first sensing unit 30. The second sensing unit 40 and the first sensing unit 30 transmit data so that the item information temporarily stored in the first sensing unit 30 is recorded in the second sensing unit 40.

[0162] The refrigerator also includes a timing module that activates when the sealed box 20 is placed in the compartment. For items with a short shelf life (such as fresh milk or yogurt), the module prompts the user to use them as soon as possible 24-48 hours before the expiration of the preset shelf life. After the expiration of the preset shelf life, the module prompts the user to remove the items from the refrigerator and discard them as soon as possible. This prompt may be provided by playing a voice message, displaying text, or a combination thereof.

[0163] Among them, the timing module stops timing the corresponding sealed box 20 on the day when the storage of the item reaches the preset storage period, and resets the timing module until the storage information of the same sealed box 20 is updated, and then restarts timing the storage time of the same sealed box 20.

[0164] The present invention also provides a method for updating the item information stored in the sealed box 20. The method for updating the item information is mainly implemented through the interaction between the vacuum base 10 and the sealed box 20. Specifically:

[0165] S1000, taking out the sealed box placed in the refrigerator in S4 from the compartment of the refrigerator, and recording the serial number of the taken-out sealed box;

[0166] S2000, open the sealed box, take out the items in the sealed box, obtain an empty sealed box, and put new items in it;

[0167] S3000: Place the sealed box containing new items on the vacuum base and determine whether the reset button of the vacuum base is activated; if so, proceed to S4000; if not, proceed to S5000;

[0168] S4000: Reset the vacuum base to repeat the process from S1 to S3 to obtain updated item information, which is recorded in the second sensing unit.

[0169] S5000, re-weighing the weight information of the new item, and recording the updated weight information in the second sensing unit; and

[0170] S6000: Place the sealed box in S3000 or S4000 in the refrigerator, control the second sensing unit and the third sensing unit to sense, and update the item information recorded under the number in S1000.

[0171] In this embodiment, if the new item in S3000 is, for example, an item different from the original item, it is determined that the reset button of the vacuum base needs to be activated to enter S4000; if the new item in S3000 is merely an item taken out of the sealed box and the weight change is caused by use, it is determined that the reset button of the vacuum base does not need to be activated to enter S5000.

[0172] In summary, the present invention proposes a method for interacting with a vacuum base and a sealed box. By inducing information exchange between the vacuum base and the sealed box, items stored within the sealed box can be stored in an optimal vacuum environment. Furthermore, by continuously inducing information between the vacuum base and the sealed box, when the information about the items stored in the sealed box changes, the vacuum base can be reset, allowing the items stored within the sealed box to remain in the optimal vacuum environment. This use of information exchange between the vacuum base and the sealed box helps overcome the problem of existing vacuuming devices being unable to interact with sealed boxes, resulting in a single operating mode for the vacuuming devices.
