[0002] Households need rice containers to store rice and other grains. However, if stored for a long time, changes in temperature and humidity can easily lead to insect infestation or mold and spoilage of the grains. To avoid such situations, vacuum rice containers have become a good choice for modern families. However, as people's living standards improve and the requirements for the preservation of other foods increase, traditional vacuum rice containers can no longer meet the needs and cannot achieve the goal of efficient and airtight preservation of family food. Other equipment needs to be added to meet these requirements. In addition to increasing living costs, multiple devices also take up a lot of family space. Summary of the Invention

[0003] In view of the fact that traditional vacuum rice containers cannot achieve the purpose of efficient sealing and preservation of household food safety, the present invention provides a multifunctional vacuum rice container, its control method and vacuum grain storage device. By creatively adding sterilization, vacuuming and sealing functions to the original functions of the vacuum rice container, it can meet the purpose of sterilization and preservation of other foods without adding household equipment, and make full use of the space inside the rice container, thereby improving space utilization.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional vacuum rice bucket, comprising a bucket body and a top cover, wherein the top cover is provided with a sterilization and sealing chamber, wherein the sterilization and sealing chamber is provided with a sealing component and a sterilization component, wherein the sealing component is used to heat seal the sealing end of the packaging bag, and the top cover also includes a vacuuming component, wherein the vacuuming component is provided with an air extraction end communicating with the sealing component.

[0005] As a further improvement of the present invention: the sealing component includes a sealing cavity and a heat-sealing structure disposed on one side of the sealing cavity, and the air extraction end is connected to the sealing cavity so that the sealing end of the packaging bag passes through the heat-sealing structure and is rolled into the sealing cavity.

[0006] As a further improvement of the present invention: the heat-sealing structure includes two rollers and heating rollers disposed on the two rollers. The outer surfaces of the two heating rollers are close together and arranged so that the packaging bag can pass between the two heating rollers and can be guided and rolled into the sealing cavity by the rolling of the two heating rollers.

[0007] As a further improvement of the present invention: the sterilization component includes an ultraviolet sterilization lamp, which is disposed on the bottom wall and / or side wall of the sterilization and packaging chamber.

[0008] As a further improvement of the present invention: the vacuuming component includes a vacuum pump, the vacuum pump is disposed inside the upper cover and the exhaust end of the vacuum pump is disposed on one side of the upper cover, the suction end of the vacuum pump is connected to the sealing cavity of the sealing component so that the vacuum pump extracts the gas in the sealing cavity and discharges it outside the upper cover through the exhaust end when vacuuming.

[0009] As a further improvement of the present invention: the vacuuming component includes a vacuum pump and a three-way valve. The vacuum pump is connected to one outlet of the three-way valve through an air extraction pipe. The two inlets of the three-way valve are respectively connected to the sealing cavity of the sealing component and the rice storage space formed between the barrel body and the top cover through air extraction pipes.

[0010] As a further improvement of the present invention: the upper cover also includes a pressure relief structure, the pressure relief structure including a pressure relief valve communicating with the rice storage space and a pressure relief rod or pressure relief button disposed on the upper cover for opening the pressure relief valve.

[0012] On the other hand, the present invention adopts the following technical solution: a control method for a multifunctional vacuum rice bucket, comprising the following control steps:

[0013] When the user places the sealed portion of the food-filled packaging bag between the two heated rollers of the sealing component, an automatic sensing signal is triggered, and the rollers rotate so that the sealed portion is rolled into the sealing cavity of the sealing component.

[0014] When the cover is closed, the sterilization components in the sterilization and packaging chamber are activated, and the food is sterilized by ultraviolet sterilization lamps. At the same time, the vacuum pump of the vacuum component is activated, and the gas in the sealed cavity and packaging bag is extracted through the extraction end to obtain the air pressure at the extraction end of the vacuum component. When the air pressure at the extraction end reaches the preset standard, the vacuum pump stops running.

[0015] The heat-sealing structure is activated to heat the two heating rollers and seal the packaging bag. After a set time, the heating stops and a power-off prompt is given.

Detailed Implementation

[0030] In order to clearly and completely understand the technical solution, the present invention will be further described in conjunction with the embodiments and accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0033] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0034] Embodiments of the present invention provide a multifunctional vacuum rice container, such as... Figure 1 and Figure 2 as well as Figure 3 As shown, the device includes a barrel body 100 and a top cover 200. A rice storage space for storing grains such as rice is formed between the barrel body 100 and the top cover 200. The rice storage space is sealed when the top cover 200 is placed over the barrel body 100. It should be noted that the sealing between the top cover and the barrel body is achieved using conventional technical means, and this embodiment does not limit it to other forms.

[0035] In this embodiment, the upper cover 200 is provided with a sterilization and packaging chamber 300, which consists of an upper cover and a cover plate covering the upper cover. The sterilization and packaging chamber 300 contains a sealing component and a sterilization component. The sealing component is used to heat-seal the opening of the packaging bag. The upper cover 200 also includes a vacuum component 400, which has an air extraction end connected to the sealing component 300. This embodiment uses the vacuum component to vacuum the packaging bag containing food, the sterilization component to sterilize the food, and the sealing component to heat-seal the opening of the packaging bag. This allows for the sterilization and preservation of other foods without adding additional household equipment.

[0036] In an optional embodiment, the sterilization component includes an ultraviolet (UV) sterilization lamp, which is disposed on the bottom or side wall of the sterilization and packaging chamber. In this embodiment, oxygen, which most microorganisms depend on for survival, is removed, preventing their survival and achieving a preservation effect. Simultaneously, for anaerobic bacteria, UV sterilization is used in conjunction with other sterilization methods to further inhibit bacterial reproduction and survival, thereby improving the preservation effect on food.

[0037] To better understand, the sealing component further includes a sealing cavity and a heat-sealing structure disposed on one side of the sealing cavity. The suction end connects to the sealing cavity so that the sealed end of the packaging bag passes through the heat-sealing structure and is then rolled into the sealing cavity. In other words, when the vacuum component is activated, the suction end can extract the gas from the sealing cavity and the packaging bag. When the user has other food sterilization and packaging needs, they pack the food to be packaged in the packaging bag and place the sealed end of the packaging bag into the heat-sealing structure, which then rolls it into the sealing cavity. The packaging bag in this embodiment can be made of a composite film material, with the inner layer being polyethylene, high-temperature resistant polypropylene, etc., and the outer layer being stretched polypropylene, polyester, nylon, etc.

[0038] Furthermore, such as Figure 4 and Figure 5As shown, the heat-sealing structure includes two rollers 310 and heating rollers 320 disposed on the two rollers 310. The outer surfaces of the two heating rollers 320 are close together so that the packaging bag 500 can pass between the two heating rollers 320 and be guided and rolled into the sealing cavity 330 by the rolling of the two heating rollers 320. That is, the user places the open end or sealed part of the packaging bag 500 between the two heating rollers 320, and then the opening end or sealed part of the packaging bag 500 can be rolled into the sealing cavity 330 by the rotation of the two heating rollers 320 using friction. The gas in the sealing cavity is then sucked out by the suction end 440 of the vacuum component 400, thus achieving the effect of simultaneously sucking out the gas in the packaging bag. In some embodiments, the heating rollers are made of heating PTC material, which heats up when electricity is applied and stops heating when the power is off.

[0039] Furthermore, such as Figure 4 As shown, the vacuuming component includes a vacuum pump 410, which is disposed inside the upper cover 200, with its exhaust end 420 located on one side of the upper cover 200. The suction end of the vacuum pump 410 is connected to the sealing cavity of the sealing component 300 so that the vacuum pump extracts the gas from the sealing cavity during vacuuming and discharges it outside the upper cover through the exhaust end. In other words, when the vacuum pump starts, it extracts gas from the sealing cavity and the packaging bag through the suction end and discharges it outside the upper cover through the exhaust end, while monitoring the internal air pressure in real time. Simultaneously, during the vacuum packaging process, an ultraviolet sterilization lamp is activated to sterilize the food inside the packaging bag. When the internal air pressure reaches a preset standard, the vacuum pump stops, completing the food packaging operation, followed by heat sealing at the sealing point.

[0040] In an optional embodiment, the vacuuming component includes a vacuum pump 410 and a three-way valve 430. The vacuum pump 410 is connected to one outlet of the three-way valve 430 via an extraction pipe. The two inlets of the three-way valve 430 are respectively connected via extraction pipes to the sealing cavity of the sealing component 300 and the rice storage space formed between the barrel body 100 and the top cover 200. In this embodiment, the vacuum pump includes two extraction ends: one extraction end is located in the sealing cavity for vacuum packaging of food, and the other extraction end is located in the barrel body for vacuuming the rice storage space.

[0041] In some embodiments, an automatic vacuum setting is used for the rice storage space. Specifically, after rice is removed or the lid is opened and then closed again, the vacuum pump is activated by default, controlling the three-way valve to switch to the inlet connecting to the rice storage space, thus vacuuming the space. Once the internal pressure reaches a preset standard, the vacuum pump stops, completing the vacuuming operation. Furthermore, by monitoring the pressure in the rice storage space in real time and setting a pressure threshold, the storage space is vacuumed again when the internal pressure exceeds the threshold, maintaining a vacuum state to ensure the storage of rice and other grains.

[0042] In some embodiments, the top cover further includes a pressure relief structure, which includes a pressure relief valve communicating with the rice storage space and a pressure relief rod or pressure relief button disposed on the top cover for opening the pressure relief valve.

[0043] On the other hand, embodiments of the present invention also provide a vacuum grain storage device, which includes a multifunctional vacuum rice bucket as described in one or an optional embodiment above. This embodiment removes oxygen, which most microorganisms depend on for survival, thus preventing their survival and achieving a preservation effect. At the same time, for anaerobic bacteria, ultraviolet light sterilization is used to assist in sterilization, which further inhibits the reproduction and survival of bacteria and improves the preservation effect of food.

[0044] On the other hand, embodiments of the present invention also provide a control method for a multifunctional vacuum rice container, wherein the multifunctional vacuum rice container described in one or an optional embodiment performs the following control steps:

[0045] When a user has other food sterilization and packaging needs, the user puts the food into a packaging bag. When the user places the sealed end of the packaging bag containing the food between the two heated rollers of the sealing component, the sensing signal is automatically triggered, and the rollers rotate so that the sealed end is rolled into the sealing cavity of the sealing component.

[0046] When the cover is closed, the sterilization components in the sterilization and packaging chamber are activated, and the food is sterilized by ultraviolet sterilization lamps. At the same time, the vacuum pump of the vacuum component is activated, and the gas in the sealed cavity and packaging bag is extracted through the extraction end to obtain the air pressure at the extraction end of the vacuum component. When the air pressure at the extraction end reaches the preset standard, the vacuum pump stops running.

[0047] The heat-sealing structure is activated to heat the two heating rollers and seal the packaging bag. After a set time, the heating stops and a power-off prompt is given. The user opens the cover and the ultraviolet sterilization lamp turns off. The packaging bag is then removed, completing the food sterilization and vacuum sealing process.

[0048] In some embodiments, the ultraviolet sterilization lamp of the sterilization component can be set to turn off after a preset time. That is, if the user puts food into the automatic packaging sterilization and forgets to open the cover to take it out, the ultraviolet sterilization lamp will automatically turn off after running for a preset time.

[0049] In some embodiments, the control method further includes the following control steps:

[0050] After the user opens the rice storage space of the vacuum rice bucket and closes the top cover, the top cover reset signal is triggered.

[0051] In response to the top cover reset signal, the vacuum pump starts and controls the three-way valve to switch to the inlet of the rice storage space formed between the bucket body and the top cover, evacuating the rice storage space and monitoring the internal air pressure.

[0052] When the internal air pressure reaches the preset standard, the vacuum pump stops operating.

[0053] In some embodiments, during normal vacuum storage without depressurization or with the top cover open, the real-time air pressure of the rice storage space is acquired, and an air pressure threshold is set. When the real-time air pressure exceeds the air pressure threshold, the vacuum pump is restarted to further extract gas from the rice storage space so that the real-time air pressure reaches the preset standard. The vacuum pump is then stopped to maintain the vacuum state in the rice storage space and ensure the storage of rice and other grains and / or food.

[0054] The above disclosures are merely one or more preferred embodiments of the present invention, intended to help understand the inventive concept of the technical solution, and are not intended to limit the present invention in any other way. Any other equivalent or conventional substitution schemes made by those skilled in the art based on the features defined by the present invention shall still fall within the scope of the present invention.
