Description

Technical Field

[0001] This application relates to the field of lunch box technology, and in particular to a split-type portable heated lunch box. Background Technology

[0002] As people's living standards improve, their demands for food are gradually increasing, and disposable lunch boxes are being replaced by environmentally friendly, reusable heated lunch boxes. Heated lunch boxes are a relatively new type of electronic product in recent years, offering heating, storage, and portability functions.

[0003] In daily life and work, people who don't want to eat fast food or quick meals often pack a pre-packaged, heated lunchbox from home so they can enjoy safe and nutritious food at school, work, or on hikes. When the food cools down, users can plug in the lunchbox to reheat it, ensuring both the food's quality and their health.

[0004] Regarding the aforementioned technologies, most heated food containers on the market currently consist of a heating element and a main body. The main body is used to hold food, while the heating element is installed at the bottom of the main body and is used to heat it. Because the main body and heating element are integrated, users need to be careful about the position of the heating element when cleaning the container after use to avoid water ingress. Existing heated food containers have certain shortcomings and therefore require improvement. Utility Model Content

[0005] To facilitate cleaning of the lunchbox and improve the user experience, this application provides a detachable portable heated lunchbox.

[0006] The technical solution for a modular portable heated lunch box provided in this application is as follows:

[0007] A detachable portable heated lunch box includes a lunch box body and a heating base. The lunch box body is detachably connected to the heating base. The heating base is provided with a protruding ring. The bottom of the lunch box body is provided with an annular groove, and the protruding ring is engaged in the annular groove. A heat-conducting plate is provided on the bottom surface of the lunch box body, and the heat-conducting plate is used to transfer heat from the heating base.

[0008] By adopting the above technical solution, the heat-conducting plate has excellent thermal conductivity. The heat generated by the heating base when powered on can be conducted to the main body of the lunchbox through the heat-conducting plate, thereby heating the food inside the lunchbox. When it is necessary to clean the lunchbox, the user can remove the entire lunchbox from the heating base and then clean it separately, thus improving the user experience.

[0009] Preferably, the main body of the food container includes a lid and a body, the body having an opening for holding food; the lid is detachably connected to the body and is used to cover the opening of the body.

[0010] By adopting the above technical solution, food can be placed inside the box, and then the lid can be placed on the box to cover the food and prevent it from being contaminated.

[0011] Preferably, the lid is connected to the box body by a snap-fit ​​mechanism, and a fixing block is provided on one side of the edge of the lid.

[0012] By adopting the above technical solution, the lid is snapped onto the box body, and the lid and box body are detachably connected by static friction. The presence of the fixing block allows the user to easily apply external force to the lid, thereby separating the lid and box body.

[0013] Preferably, the outer periphery of the box body is provided with a heat insulation layer.

[0014] By adopting the above technical solution, the insulation layer can keep the box warm and reduce the heat loss of the food inside the box.

[0015] Preferably, it also includes a sealing element, wherein the lid has an exhaust hole, the sealing element is detachably connected to the lid, and is used to block the exhaust hole.

[0016] By adopting the above technical solution, when the heating base heats the main body of the food container, the sealing element blocks the vent, achieving a seal and improving the heating effect of the food. After the food is heated, the sealing element can be removed from the vent, and the hot air is discharged into the atmosphere through the vent, achieving heat dissipation.

[0017] Preferably, the outer surfaces of both the lid and the body of the box are coated with a paint layer.

[0018] By adopting the above technical solution, the paint layer can improve the aesthetics of the outer surface of the box lid and body.

[0019] Preferably, the heating base is provided with a socket for connecting a power supply cable.

[0020] By adopting the above technical solution, one end of the wire can be plugged into a power socket, and the other end can be plugged into a socket to power the heating base.

[0021] Preferably, the heating base is provided with a push switch and an indicator light. The indicator light is located on one side of the push switch. The push switch is used to control the operation of the heating base, and the indicator light is used to display the working status of the heating base.

[0022] By adopting the above technical solution, after the heating base is powered on, the user manually controls the push switch to make the heating base run and heat the main body of the lunch box. The user can observe the indicator light to judge the working status of the heating base, and can promptly disconnect the power when the main body of the lunch box has finished heating.

[0023] Preferably, the bottom of the heating base is provided with a plurality of support pads, which are spaced apart and are made of anti-slip material.

[0024] By adopting the above technical solution, the support pad can support the entire heating base. At the same time, the support pad made of anti-slip material has a high coefficient of friction, making it less likely to move relative to the contact surface, thus improving the stability of the heating base.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] (1) By separating the main body of the lunch box and the heating base, when the main body of the lunch box needs to be cleaned, the user can remove the entire main body of the lunch box from the heating base and clean it separately without having to worry about whether the heating base will get wet.

[0027] (2) By setting a fixing block on the lid, the presence of the fixing block makes it convenient for the user to apply external force to the lid, thereby separating the lid and the body of the box.

[0028] (3) By setting push switches and indicator lights, users can control the operation of the heating base by pushing switches and judge the operating status of the heating base by the indicator lights, thereby improving the safety of use. Attached Figure Description

[0039] This application discloses a split-type portable heated lunch box. (Refer to...) Figure 1 and Figure 2 The heated lunchbox includes a lunchbox body 1 and a heating base 2. The lunchbox body 1 is detachably connected to the heating base 2. A protruding ring 3 is connected to the side of the heating base 2 facing the lunchbox body 1. An annular groove 4 is formed at the bottom of the lunchbox body 1, and the protruding ring 3 is engaged in the annular groove 4. The connection between the lunchbox body 1 and the heating base 2 is achieved by the action of static friction. A heat-conducting plate 5 is provided on the bottom surface of the lunchbox body 1 to transfer the heat generated by the heating base 2.

[0040] After the food in the main body 1 of the lunchbox cools down, the heating base 2 can be powered on. Due to the excellent thermal conductivity of the heat-conducting plate 5, the heat generated by the heating base 2 can be conducted to the interior of the lunchbox 1 through the heat-conducting plate 5, thereby heating the food inside the lunchbox 1. When it is necessary to clean the lunchbox 1, the user can remove the entire lunchbox 1 from the heating base 2 and then clean it separately, thereby improving the user experience.

[0041] Specifically, the main body 1 of the food container includes a lid 11 and a body 12. The body 12 has an opening and is used to hold food. A heat-conducting plate 5 is disposed on the bottom surface of the body 12, and the body 12 is detachably mounted on the heating base 2. The lid 11 is detachably connected to the body 12 and is used to cover the opening of the body 12 to prevent the food inside the body 12 from being contaminated. In this embodiment, the lid 11 is connected to the body 12 by a snap-fit ​​mechanism. A fixing block 14 is also integrally connected to one edge of the lid 11. The fixing block 14 is used for the user to apply force with their thumb, making it convenient for the user to apply external force to the lid 11, thereby separating the lid 11 and the body 12 from each other.

[0042] Combination Figure 3 A sealing element 7, made of elastic material such as rubber, is detachably connected to the lid 11. The lid 11 also has a vent 6, and the sealing element 7 is detachably installed on the vent 6 by snap-fit ​​or plug-in connection, thus blocking the vent 6. When the heating base 2 heats the food container body 1, the sealing element 7 blocks the vent 6, achieving a seal and improving the heating effect of the food. After the food is heated, the sealing element 7 can be removed from the vent 6, and the hot air is discharged into the atmosphere through the vent 6, achieving heat dissipation. In some embodiments, a heat insulation layer is fixedly connected to the outer periphery of the container body 12, and the heat insulation layer is made of heat-insulating material. The heat insulation layer can keep the container body 12 warm, reducing heat loss from the food inside the container body 12. The outer surfaces of both the lid 11 and the container body 12 are coated with a paint layer, which can improve the aesthetics of the entire food container body 1, thereby increasing user satisfaction.

[0043] Combination Figure 4 In addition, the heating base 2 is equipped with a socket 8 for connecting the power cord. A push switch 9 and an indicator light 10 are also installed on one side of the socket 8. The push switch 9 controls the operation of the heating base 2, and the indicator light 10 displays the working status of the heating base 2. When the heating base 2 is powered on, the user manually controls the push switch 9 to activate the heating base 2 and heat the lunchbox body 1. The user can observe the indicator light 10 to determine the working status of the heating base 2 and promptly disconnect the power after the lunchbox body 1 has finished heating, improving safety.

[0044] The heating base 2 is further equipped with four support pads 13 fixedly connected to its bottom. These support pads are made of anti-slip material, which may be, but is not limited to, rubber or polyurethane. The support pads 13 are spaced apart and lie on the same plane. The support pads 13 can support the entire heating base 2. At the same time, the support pads 13 have a high coefficient of friction, making it less likely to move relative to the contact surface, thus improving the stability of the heating base 2 when placed.

[0045] The implementation principle of the detachable portable heated lunch box in this application embodiment is as follows: After the food in the lunch box body 1 cools down, the heating base 2 can be powered on. Due to the good thermal conductivity of the heat-conducting plate 5, the heat generated by the power-on heating base 2 can be conducted to the lunch box body 1 through the heat-conducting plate 5, thereby heating the food inside the lunch box body 1. When it is necessary to clean the lunch box body 1, the user can remove the entire lunch box body 1 from the heating base 2 and then clean it separately, thereby improving the user experience.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
