Description

Technical Field

[0001] This utility model belongs to the field of tableware design technology, specifically relating to a food container with intelligent heating function. Background Technology

[0002] Traditional bowls lack heating functions, causing food to cool down easily during use, which is detrimental to health and requires repeated reheating, diminishing the dining experience. This is especially true for young children, who eat more slowly and are more prone to food cooling down. Furthermore, their digestive systems are not fully developed, and cold food can be harmful to their growth. Generally, cooled food needs to be reheated multiple times, particularly during colder seasons.

[0003] To improve heat retention, sandwich-structured bowls have emerged in recent years. These bowls employ a double-layer structure with an air or vacuum layer in between. This air or vacuum layer significantly reduces the bowl's thermal conductivity, thus slowing down the cooling process of food. However, existing sandwich bowls are prone to leakage after a few uses. Water seeping into the sandwich layer not only causes hygiene problems and makes cleaning difficult, but also noticeably reduces heat retention. Therefore, the overall heat retention performance of sandwich bowls needs further improvement. Utility Model Content

[0004] This invention provides a food container with intelligent heating function. The bowl has an automatic heating function and can maintain the temperature of the food inside the bowl very well.

[0005] A food container with intelligent heating function includes a container body, the container body including an inner shell and an outer shell, the outer shell surrounding the outer wall of the inner shell and the top ends of the outer shell and sealing each other; a heating element assembly is provided in the sealed space enclosed by the inner shell and the outer shell, the heating element assembly including a heating element thermally connected to the inner shell and a power source.

[0006] The food container of this invention can be used as a bowl, plate, etc.

[0007] The inner and outer shells can be made of commonly used materials. A container lid or similar accessory can be added as needed to further enhance insulation. Alternatively, the inner shell can be made of stainless steel, and the outer shell of plastic.

[0008] Preferably, the outer shell is provided with a display window; a temperature display component is provided in the sealed space corresponding to the position of the display window. The temperature display component can adopt existing product structures, such as a digital tube display screen. With this technical solution, the temperature inside the bowl can be observed in real time through the display window. The temperature display component generally includes a light source, a light-shielding plate, and a light-transmitting film. The light source is controlled by a control board, and the light-shielding plate and light-transmitting film enable high-definition display of the target temperature.

[0009] Preferably, the top of the inner shell is provided with a folded edge for sealing and fixing with the outer shell, and a sealing element is provided between the folded edge and the outer shell. The folded edge design further improves the fixing and sealing performance between the inner shell and the outer shell.

[0010] Preferably, the folded edge is a semi-enclosed structure that partially surrounds the top of the outer shell; the sealing element is one or more sealing rings. The semi-enclosed structure better ensures a tight seal. The sealing element is generally an elastic sealing ring, and one or more can be used. To further enhance the sealing and fixing strength, a combination of sealing rings and adhesive bonding can also be used. Alternatively, an interference fit or a combination of sealing rings or adhesive bonding can be used to achieve a tight seal between the inner and outer shells.

[0011] Preferably, the sealing element includes a circumferential sealing ring disposed between the folded edge and the outer wall of the housing, and an end sealing ring disposed between the folded edge and the top of the housing. One or more of either the circumferential or end sealing rings may be provided. When fixed by adhesive bonding, the end sealing ring can be replaced with a high-temperature resistant adhesive.

[0012] Preferably, the heating element has a concave structure that surrounds the bottom of the inner shell, further improving heating performance.

[0013] Preferably, the heating element is bonded and fixed to the outer wall of the bottom of the inner shell. This bonding and fixing can be achieved using existing high-temperature resistant adhesives.

[0014] Preferably, the sealed space is further provided with a heat insulation plate; the power supply is located below the heat insulation plate; and the heating element is located above the heat insulation plate. Preferably, the sealed space is provided with a temperature sensor for detecting the inner shell temperature and a control board, which receives the temperature signal from the temperature sensor and controls the operation of the heating element. Using this technical solution, automatic heating of the bowl can be achieved.

[0015] Preferably, the housing is provided with an input area for adjusting and controlling the temperature. The control board automatically controls the operation of the heating element based on the input temperature value and the received temperature signal from the temperature sensor. The sealed space is provided with a corresponding input circuit board and a trigger switch, etc.; the trigger switch can be a spring-loaded touch switch.

[0016] The power source can employ a common battery structure or a rechargeable battery. When using a rechargeable battery, the outer casing has contact points for charging the power source. Charging is facilitated by using these contact points and an external magnetic charging head. As a further preferred embodiment, the outer casing has recessed and raised fixing grooves, and the contact points are positioned within these grooves to further prevent the positive and negative electrodes from being reversed, thereby enabling fast and accurate charging by the magnetic charging head. Furthermore, the contact points are sealed and fixed to the outer casing by a sealing element.

[0017] Compared with the prior art, the beneficial effects of this utility model are reflected in:

[0018] The food container provided by this utility model has an automatic heating function, which solves the problem that the existing technology cannot keep the food inside the bowl warm because ordinary bowls cannot keep it warm; it is especially suitable for holding food that needs to be kept warm for a long time or for use by children, and is more practical.

[0019] The food container of this invention has an independent charging function, which greatly improves its service life; at the same time, by setting a temperature display component, users can observe the temperature inside the bowl in real time, further ensuring the heat preservation effect.

The control board receives the temperature signal from the temperature sensor 503 and controls the operation of the heating element 501.

[0030] The heating element 501 is a concave structure that surrounds the bottom of the inner shell. It is set on the outer wall of the bottom side of the inner shell and is bonded and fixed to the bottom of the inner shell 101 with a high-temperature resistant adhesive, which further improves the heating performance.

[0031] refer to Figure 4 and Figure 5 and Figure 6 The sealed space also includes a horizontally arranged heat insulation plate 505; a power supply 502 and a control board 504 are located below the heat insulation plate 505; and a heating element 501 is located above the heat insulation plate. A charging circuit board 606, electrically connected to the power supply 502, is also located in the sealed space below the heat insulation plate 505. The positive and negative contact points of the charging circuit board are located on the outer casing via a sealing element 607 (which can be a sealing gasket), and the circuit board 606 is fixed to the mounting bracket 607. During use, charging is performed using an external magnetic charging head 506. Furthermore, the outer casing has a recessed and raised fixing groove, and the contact points are located within this groove. The shape of the recessed and raised fixing groove corresponds to the shape of the external magnetic charging head 506, enabling rapid alignment and charging of the positive and negative contact points by the external magnetic charging head 506.

[0032] The outer casing has a display window 402; a temperature display component 507 is located in the sealed space corresponding to the display window.

Simultaneously, the outer casing also has a temperature input area. An input circuit board 604 connected to the control board and a spring-loaded touch switch 508 are fixed in the sealed space. The spring-loaded touch switch is in close contact with the temperature input area, triggering the switch upon contact. The controller automatically controls the heating element's operation based on the input temperature value and the received temperature sensor signal. The input circuit board 604 uses electrostatic induction input, further ensuring the overall sealing of the outer casing. The temperature display component 507, input circuit board 604, etc., are fixed to the heat insulation plate 505 via a display mounting bracket 605.

[0033] See Figure 4 and Figure 7 The inner shell 101 has a folded edge 701 at its top for sealing and fixing with the outer shell 102, and a sealing element is provided between the folded edge and the outer shell. The folded edge design further improves the sealing performance between the inner shell and the outer shell. The sealing element includes a circumferential sealing ring 702 disposed between the folded edge and the top outer wall of the outer shell, and an end sealing ring 703 disposed between the folded edge and the top of the outer shell. One or more circumferential sealing rings or end sealing rings may be provided. The end sealing ring 703 can be replaced by an adhesive. When the end sealing ring 703 is used, the inner shell and the outer shell can be fixed by an interference fit, while the circumferential sealing ring 702 further enhances the sealing performance.
