Description

Technical Field

[0001] The invention relates to the technical field of tableware, and in particular to an intelligent portable multifunctional lunch box. Background Art

[0002] A lunch box is a container used to hold and carry food, usually for carrying homemade or purchased meals, bento, etc. when going out. It is a portable container that can easily store food and keep it fresh and warm. Lunch boxes vary in design and material, common types of lunch boxes include:

[0003] Plastic lunch boxes: Plastic lunch boxes are lightweight and durable, and are commonly found among students, office workers, and travelers. They are usually designed with good sealing properties to effectively prevent food leakage and contamination.

[0004] Stainless steel lunch box: Stainless steel lunch box has excellent durability and corrosion resistance, and usually adopts a layered design to separate different types of food and avoid mixed food flavors.

[0005] Glass lunch box: Glass lunch boxes are easy to clean and do not easily produce odors, making them suitable for storing all kinds of food. However, glass lunch boxes are relatively heavy and are not suitable for situations where they need to be carried frequently.

[0006] Vacuum insulated lunch box: Vacuum insulated lunch box usually has heat preservation and cold preservation functions, which can keep the temperature of food for a period of time. It is suitable for situations where the temperature of food needs to be kept for a long time.

[0007] Electric lunch box: The electric lunch box has a built-in heating device that can heat food through power supply. It is suitable for occasions where food needs to be heated at any time, such as office workers or travelers.

[0008] Multi-layer lunch box: The multi-layer lunch box is designed with multiple layers, which can be loaded with different types of food separately, maintaining the original flavor of the food and making it convenient to carry a variety of food.

[0009] Regardless of the type of lunch boxes, they are portable containers commonly used in people's daily lives. They can meet the needs of different groups of people and are convenient for carrying food to dine out or storing food.

[0010] The groups that often use lunch boxes are generally office workers, students, and people who engage in production and business activities in specific or unspecified places for a long time, such as truck drivers, vendors, etc. The above groups mainly need to keep warm and heat lunch boxes, but due to site conditions, the places where they are located often do not have heating conditions or heating requires a long queue and delays rest time. At the same time, as people pay more attention to physical health, they pay more attention to nutritional matching and calorie intake management during meal preparation, but homes generally do not have the corresponding conditions. Most of the existing lunch boxes can only meet the needs of holding meals, and a few can achieve plug-in heating or charging heating. The refrigeration of meals requires the use of refrigerators, but most users do not have this condition. In the hot summer, meals are easy to go out. The deterioration phenomenon affects physical health and safety. At present, lunch boxes with heating function mostly use resistance wire to generate heat and then heat the food. The resistance wire is mostly concentrated at the bottom, and the upper layer of food is heated unevenly, which may cause the lower layer and the outer layer of food to be overheated while the upper layer of food is still not heated. At the same time, the staple food and dishes are often separated in the national eating habits, and the degree of heating required is not the same, so they need to be distinguished during the heating process. In addition, after the meal, the existing working and living conditions often cannot meet the timely cleaning of lunch boxes and tableware. Food residues that are not cleaned in time are likely to cause odor and the breeding of bacteria and viruses. From the perspective of the lunch box user group, self-heating, differentiated heating, nutritional matching and timely cleaning after meals are all urgent problems to be solved.

[0044] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0045] See also Figure 1-Figure 6 , a smart portable multifunctional lunch box, comprising a housing 1, and further comprising:

[0046] The inner liner 2 is clamped to the top of the inner cavity of the outer shell 1, and a sealing gasket is fixedly installed at the clamping position between the inner liner 2 and the outer shell 1, and the sealing gasket can achieve sealing at the clamping position between the inner liner 2 and the outer shell 1;

[0047] The temperature control element 3 is fixedly mounted at the bottom of the inner cavity of the housing 1;

[0048] A flip cover 11, which is hinged to the top of one side of the housing 1;

[0049] Smart components 4, which are installed on both sides of the flip cover 11;

[0050] The ultrasonic oscillator 5 is fixedly mounted on the bottom of the flip cover 11 .

[0051] The inner liner 2 is recessed on both sides and raised in the middle to be divided into two interconnected chambers. Water outlet pipes 21 are fixedly installed on both sides of the bottom of the inner liner 2. The water outlet pipe 21 is connected to the inner cavity of the inner liner 2. The bottom of the water outlet pipe 21 is fixedly connected to the bottom of the inner cavity of the outer shell 1 and is connected to the outside. A water outlet valve 22 is fixedly installed at the connection between the bottom of the inner liner 2 and the water outlet pipe 21. Water inlet pipes 23 are fixedly installed on both sides of the inner liner 2. The water inlet pipe 23 is connected to the inner cavity of the inner liner 2. A water inlet valve 24 is fixedly installed at the connection between the outer side of the inner liner 2 and the water inlet pipe 23.

[0052] An annular groove 25 is formed on the top of the inner container 2, and an annular sealing gasket 14 is fixedly installed on the bottom of the flip cover 11. The annular sealing gasket 14 can be snapped onto the inner wall of the annular groove 25 to achieve sealing between the two.

[0053] Specific implementation method: The user puts the prepared food in the inner pot 2, and the dishes and staple food are placed in the two chambers of the inner pot 2 respectively, and flips the flap 11 to cover the top of the inner pot 2. The flap 11 and the inner pot 2 are connected and sealed at the connection through the annular groove 25 and the annular sealing gasket 14 to prevent dust and germs in the air from entering the inner pot 2 and contaminating the food;

[0054] During the carrying process, the user can use a cloth bag to place the device. During the storage process, the temperature control element 3 is controlled to cool down by controlling the display screen 42. The space between the outer shell 1 and the inner pot 2 is divided into two independent chambers by the partition 15, one of which is filled with a mixture of water and detergent, and the other is filled with water. The temperature control element 3 cools down and drives the temperature of the liquid between the outer shell 1 and the inner pot 2 to decrease, thereby reducing the temperature of the food. Since the two chambers of the inner pot 2 are cylindrical and can fully contact the liquid, they have a better heat conduction effect. Before eating, the user controls the temperature of the temperature control element 3 to increase, and finally realizes the heating of the food. The temperature control element 3 has the functions of cooling and heating. This is a prior art and will not be described in detail here. The temperature control element 3 is electrically connected to the battery 7, and the battery 7 provides it with electrical energy. At the same time, it is also controlled by the internal PLC programming program;

[0055] After the user heats the food, he / she can open the flip cover 11 and eat. After finishing eating, the user discards larger food residues such as bones, flips the flip cover 11, and covers the top of the inner pot 2. At this time, the water inlet valve 24 on one side is controlled to pump a mixture of water and detergent into the inner pot 2 through the water inlet pipe 23. At this time, the mixture of water and detergent fills the inner pot 2, and the ultrasonic oscillator 5 is started. The ultrasonic wave is transmitted to the surface of the inner pot 2 through the liquid to remove dirt such as grease and food residues attached to the surface. After the ultrasonic oscillation washing is completed, the two water outlet valves 22 are opened to discharge the mixed liquid and food residues through the water outlet pipe 21. At this time, the user closes the water outlet valve 22, opens the other water inlet valve 24, pumps water into the inner pot 2 through the water inlet pipe 23, repeats the above ultrasonic oscillation washing operation, and cleans the inner wall of the inner pot 2.

[0056] Since the heated liquid has a certain residual temperature, the use of the liquid can achieve a better cleaning effect. By separating the liquid and using it in batches, the utilization rate of the liquid can be improved and resources can be saved. The water outlet valve 22 and the water inlet valve 24 have a pressurizing function. This is a prior art and will not be described in detail here. The ultrasonic oscillator 5, the water outlet valve 22 and the water inlet valve 24 are electrically connected to the battery 7, and are also controlled by the internal PLC programming program.

[0057] The inner liner 2 and the inner side of the outer shell 1 are both made of 304 stainless steel, and the outer side of the outer shell 1 is made of materials such as rubber with good heat insulation performance.

[0058] Smart Components 4 include:

[0059] An identification element 41, which is fixedly mounted on the bottom of the flip cover 11;

[0060] A control display screen 42, which is rotatably connected to the top of the flip cover 11;

[0061] The first turn button 43 is rotatably connected to one side of the top of the flip cover 11 .

[0062] Specific implementation method: the user puts the food in the inner pot 2, and then flips the flap 11 and covers it on the top of the inner pot 2. The identification element 41 identifies the food and transmits the identified data to the control display screen 42. The control display screen 42 has a built-in PLC controller, which can compare the identified data with the data in the database to determine the type of food. At the same time, a pressure sensor is built-in at the bottom of the inner pot 2. The pressure sensor transmits the pressure data to the control display screen 42 and converts it into food weight data. Under the control of the PLC controller, calorie analysis data and nutritional recipe suggestions are generated and displayed on the control display screen 42, meeting the user's demand for nutritional balance. The identification element 41 has imaging and data transmission functions, and the control display screen 42 stores food image information and corresponding calorie data. This is a prior art and will not be described in detail here. The identification element 41, the control display screen 42 and the pressure sensor are electrically connected to the battery 7, and are also controlled by the internal PLC programming program.

[0063] When using the control display screen 42, the user can flip the control display screen 42 to face the front side. When not in use, the user can also flip the control display screen 42 to face the back side. The main body of the control display screen 42 is embedded in the groove on the top of the shell 1. The knob 43 is manually rotated to a certain angle. The bottom of the knob 43 respectively abuts against the back of the control display screen 42 and the top of the shell 1, thereby fixing and protecting the control display screen 42.

[0064] A partition 15 is fixedly installed in the middle of the inner cavity of the shell 1, and the partition 15 isolates the shell 1 into two independent chambers. The top of the partition 15 abuts against the bottom of the inner tank 2. Water injection hoses 12 are fixedly installed on both sides of the shell 1, and a water injection valve 13 is fixedly installed at the connection between the shell 1 and the water injection hose 12.

[0065] Specific implementation method: The user can inject water and detergent into the chamber between the outer shell 1 and the inner tank 2 through the water injection valve 13 and the water injection hose 12. After cleaning is completed, if the user believes that further cleaning is necessary, water and detergent can be added again to repeat the washing operation, which is convenient for the user to clean the lunch box anytime and anywhere. The water injection valve 13 is controlled by the internal PLC programming program, and the partition 15 plays a partition role, which is made of 304 stainless steel.

[0066] An auxiliary component 6 is installed on one side of the shell 1, and the auxiliary component 6 includes: an auxiliary warehouse 61, the auxiliary warehouse 61 is fixedly installed on one side of the shell 1, an auxiliary box 62 is slidably connected to the inner side of the auxiliary warehouse 61, a handle 63 is fixedly installed on one side of the auxiliary box 62, and a buckle 64 is rotatably connected to one side of the auxiliary warehouse 61.

[0067] Specific implementation method: When using a lunch box, users often need to prepare their own tableware, but currently most of the tableware is packaged or placed separately, and it is easy to miss it. The lunch box avoids the above problem by setting an auxiliary component 6 on one side of the outer shell 1. The auxiliary box 62 can hold tableware, seasoning packets, etc., and can slide along the inner wall of the auxiliary bin 61 under the pull of the handle 63. It can be pulled out when in use and pushed back when not in use. In order to prevent the auxiliary box 62 from naturally slipping out during carrying, after pushing the auxiliary box 62 back, manually rotate the second knob 64 until one side of the second knob 64 is respectively in contact with one side of the auxiliary box 62 and the auxiliary bin 61, so as to fix the auxiliary box 62. The corresponding tableware can be put into the inner tank 2 for washing after eating, and then put into the auxiliary box 62 after washing.

[0068] A storage battery 7 is fixedly mounted on one side of the housing 1 and is used to provide electric energy to the lunch box.

[0069] The drying element 8 is fixedly mounted at the bottom of the flap 11. After washing is completed, the drying element 8 blows out hot air to dry the inner cavity of the liner 2 to prevent the accumulation of liquid in the inner cavity of the liner 2. The drying element 8 is electrically connected to the battery 7 and is also controlled by the internal PLC programming program. The drying element 8 can blow out hot air. This is a prior art and will not be elaborated on here.

[0070] Working principle: the user places the food in the inner pot 2, flips the flap 11 to seal it, identifies the type of food through the intelligent component 4, measures the weight of the food, obtains the calorie data, provides nutritional recipe suggestions and displays them on the control display screen 42. The control display screen 42 is flipped over and fixed for protection after use. During the carrying, storage and heating process, the temperature control element 3 is controlled to cool or heat respectively to achieve refrigeration and heating of the food. After eating, the user controls the water inlet valve 24, the water outlet valve 22 and the ultrasonic oscillator 5 to oscillate and clean the food residues remaining in the inner pot 2, and performs secondary or multiple cleaning operations after oscillation and cleaning depending on the situation.
