Description

Technical Field

[0001] This utility model relates to the field of self-heating packaging boxes, specifically to self-heating pack structures and self-heating food packaging boxes. Background Technology

[0002] Self-heating mala tang is a convenient fast food product that combines self-heating technology with the traditional mala tang flavor. It achieves rapid heating through a built-in heating pack, without the need for an additional fire source or electrical appliance. It is suitable for various scenarios such as outdoor, office, and home consumption. The package usually contains a heating pack (the main ingredients are iron powder, activated carbon, salt, etc.) and a food packet. After adding cold water, the heating pack generates high temperature through a chemical reaction (exothermic oxidation of iron), and the steam heats the upper food. It can be eaten in 10-15 minutes.

[0003] Existing self-heating mala tang (a type of spicy hot pot) requires users to first place the heating pack and cold water into the heating bowl, and then quickly place the food bowl into the heating bowl for heating. This causes the heating pack and cold water to heat up too quickly. If the food bowl is not placed into the heating bowl in time, the hot water may boil over, creating a safety hazard. Furthermore, the heating bowl is very hot when the heating pack is in use, which can easily cause burns to the user's hands. In addition, the heating pack lacks a restraining function, which makes it easy for the food bowl to be squeezed and tilted, resulting in uneven heating of the food in the heating bowl. Utility Model Content

[0004] The purpose of this utility model is to provide a self-heating pack structure and a self-heating food packaging box to solve the problems in the prior art that there are safety hazards if the food container is not placed into the heating container in time when the heating pack is heating, and the lack of limiting functions when using the heating pack.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-heating pack structure and a self-heating food packaging box, including a heating basin containing a food container, and further including: a water injection mechanism disposed on the heating basin, the water injection mechanism including a water injection cavity opened in the side wall of the heating basin, a plurality of water injection ports penetrating the water injection cavity being opened at the top of the heating basin, and a plurality of overflow holes penetrating the water injection cavity being opened inside the heating basin; a heating mechanism disposed on the inner bottom side of the heating basin, the heating mechanism including a limiting groove opened in the inner bottom side of the heating basin, the heating basin being positioned by limiting the heating pack through the limiting groove; and an observation mechanism fixedly disposed on the side wall of the heating basin, the observation mechanism including a plurality of observation windows fixedly disposed on the side wall of the heating basin.

[0006] Furthermore, the water injection mechanism also includes a water injection trough located at the top of the heating basin, and several of the water injection ports are located on the bottom side inside the water injection trough.

[0007] Furthermore, the heating mechanism also includes several snap-fit ​​holes fixedly disposed on the bottom side inside the limiting groove, and several snap-fit ​​protrusions fixedly disposed on the heating pack; and the snap-fit ​​holes and snap-fit ​​protrusions are engaged with each other.

[0008] Furthermore, the observation mechanism also includes scales engraved on the observation window, and the observation window is made of transparent material.

[0009] Furthermore, a protective cover is fitted onto the top of the heating basin, and a vent hole is provided on the top of the protective cover; and the vent hole is connected to the interior of the heating basin.

[0010] Furthermore, a sealing ring is fixedly provided on the top of the heating basin, and the heating basin is sealed to the protective cover through the sealing ring.

[0011] Compared with existing technologies, the self-heating pack structure and self-heating food packaging box provided by this utility model, by setting up a heating basin, makes it easy to place the food container inside the heating basin, and then the heating pack, together with cold water, heats the food. A water injection cavity is opened on the side wall of the heating basin, and a water injection groove and several water inlets are opened on the top of the heating basin. This allows the food container and food to be placed inside the heating basin first, and then cold water is injected from the water injection groove to fill the water injection cavity, ensuring that the water injection cavity is filled with water. Cold water then flows into the heating basin through several overflow holes, thus avoiding the need to add water first to react with the heating pack before quickly placing the food and ingredients into the heating basin. This improves the safety of using the heating basin and the food basin. At the same time, the water inlet chamber filled with cold water can improve the heat insulation effect of the heating basin's side wall, preventing burns caused by excessively high side wall temperatures. Furthermore, the heating pack can be positioned by the limiting groove during use, ensuring that the heating pack is directly below the food basin for heating, resulting in more even heating of the food in the basin.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] As attached Figure 1 To be continued Figure 6 As shown:

[0023] Example 1:

[0024] This utility model provides a self-heating pack structure and a self-heating food packaging box, including a heating basin 1, in which a food container 7 is loaded, and further including: a water injection mechanism disposed on the heating basin 1, the water injection mechanism including a water injection cavity 14 opened in the side wall of the heating basin 1, a plurality of water injection ports 8 opened at the top of the heating basin 1 penetrating the water injection cavity 14, and a plurality of overflow holes 9 opened inside the heating basin 1 penetrating the water injection cavity 14; a heating mechanism disposed on the inner bottom side of the heating basin 1, the heating mechanism including a limiting groove 11 opened in the inner bottom side of the heating basin 1, the heating basin 1 being limited by the limiting groove 11 to hold a heating pack 10; and an observation mechanism fixedly disposed on the side wall of the heating basin 1, the observation mechanism including a plurality of observation windows 2 fixedly disposed on the side wall of the heating basin 1.

[0025] The heating basin 1 facilitates the placement of food into the food container 7, which is then heated by a heating pack 10 in conjunction with cold water. A water inlet cavity 14 is located on the side wall of the heating basin 1, and a water inlet trough 6 and several water inlets 8 are located on the top of the heating basin 1. This allows the food container 7 and food to be placed inside the heating basin 1 before cold water is injected from the water inlet trough 6 to fill the water inlet cavity 14. Excess cold water in the water inlet cavity 14 is then drained into the heating basin 1 through several overflow holes 9. The heating basin 1 is placed inside the heating plate, thus avoiding the need to add water first to react with the heating pack 10 before quickly placing the food and ingredients 7 into the heating basin 1. This improves the safety of using the heating basin 1 and the food and ingredients 7. At the same time, the water inlet 14 filled with cold water can improve the heat insulation effect of the side wall of the heating basin 1, preventing burns caused by excessively high temperature of the side wall of the heating basin 1. When in use, the heating pack 10 can be positioned by the limiting groove 11, so that the heating pack 10 can be placed directly below the food and ingredients 7 for heating, thereby making the food and ingredients 7 heated more evenly.

[0026] refer to Figure 2 , Figure 3 and Figure 6 The water injection mechanism includes a water injection chamber 14, a water injection port 8, an overflow hole 9, and a water injection tank 6;

[0027] The heating basin 1 allows the food container 7 to be placed inside for heating. A water inlet cavity 14 is provided on the side wall of the heating basin 1, and several water inlets 8 are provided on the top of the heating basin 1, connecting to the interior of the water inlet cavity 14. Several overflow holes 9 are also provided on the inner wall of the heating basin 1, connecting to the interior of the water inlet cavity 14. This allows the food container 7 to be placed directly into the heating basin 1 when heating food, and then cold water is injected into the water inlet cavity 14 through the water inlets 8. When there is too much water, the cold water in the water injection chamber 14 can flow out from several overflow holes 9 on the inner wall of the heating basin 1 to the bottom of the heating basin 1. This allows the food container 7 to be placed into the heating basin 1 first before adding water, avoiding the need to add water first to react with the heating pack 10 and then quickly place the food container 7 and food into the heating basin 1. This improves the safety of using the heating basin 1 and the food container 7. The cold water injected into the water injection chamber 14 on the side wall of the heating basin 1 also prevents the side wall of the heating basin 1 from getting too hot, further preventing the side wall of the heating basin 1 from scalding the user.

[0028] Meanwhile, a water inlet 6 is provided on the top of the heating basin 1, and several water inlets 8 are designed on the bottom inside the water inlet 6. This allows cold water to be directly injected into the water inlet 6 and then into the water inlet 14 through the water inlets 8 when the heating basin 1 and the water inlet 14 are used for water filling. This improves the ease of use of the heating basin 1, and allows water to be conveniently added to the heating basin 1 after the food is placed in the food container 7.

[0029] refer to Figure 3 , Figure 4 and Figure 5 The heating mechanism includes a limiting groove 11, a snap-fit ​​hole 12, a heating pack 10, and a snap-fit ​​protrusion 13;

[0030] By opening a limiting groove 11 at the middle position of the bottom inside the heating basin 1, the heating basin 1 can be easily placed with the heating pack 10 through the limiting groove 11, so that the heating pack 10 can be easily placed in the middle position of the bottom inside the heating basin 1 through the limiting groove 11. The limiting groove 11 is in the shape of a groove, so as to prevent the food basin 7 from pushing or tilting the heating pack 10 when it is placed and used.

[0031] Meanwhile, snap-fit ​​holes 12 are fixedly connected at the four corners of the inner limit groove 11, and snap-fit ​​protrusions 13 are fixedly connected at the four corners of the heating pack 10. The snap-fit ​​holes 12 and snap-fit ​​protrusions 13 are connected to each other, so that when the heating pack 10 is placed on the inner bottom side of the heating basin 1 through the limit groove 11, several snap-fit ​​protrusions 13 can be snapped into several snap-fit ​​holes 12, thereby improving the stability of the heating pack 10 when placed in the limit groove 11, thus facilitating the uniform heating of the food inside the food basin 7.

[0032] refer to Figure 1 The observation mechanism includes observation window 2;

[0033] By fixing several observation windows 2 to the side wall of the heating basin 1 and making the observation windows 2 transparent, the water level in the water injection chamber 14 and the heating basin 1 can be observed through the observation windows 2 when the heating basin 1 is in use. The observation windows 2 are engraved with scales, so that when cold water is injected into the water injection chamber 14, the water level in the water injection chamber 14 and the heating basin 1 can be checked by referring to the scales on the observation windows 2. This makes it convenient to inject the heating pack 10 in the heating basin 1 with a suitable level of cold water for heating.

[0034] Example 2:

[0035] refer to Figure 1 and Figure 2A protective cover 4 is snapped onto the top of the heating basin 1, and a vent 5 is provided on the top of the protective cover 4. When a food container 7 is placed inside the heating basin 1, the hot steam generated by the food heating can be discharged through the vent 5. A sealing ring 3 is fixedly connected to the top side of the heating basin 1, so that when the protective cover 4 is snapped onto the top of the heating basin 1 for use, the sealing ring 3 can seal the protective cover 4 to prevent water vapor from leaking out from the connection between the heating basin 1 and the protective cover 4, thereby improving the safety of the protective cover 4.

[0036] Working Principle: A heating basin 1 is provided, allowing food containers 7 to be placed inside for heating. A water inlet cavity 14 is located on the side wall of the heating basin 1, and several water inlets 8 are located on the top of the heating basin 1, connecting to the interior of the water inlet cavity 14. Several overflow holes 9 are located on the inner wall of the heating basin 1, also connecting to the interior of the water inlet cavity 14. This allows the food container 7 to be placed directly into the heating basin 1 when heating food, and then cold water is injected into the water inlet cavity 14 through the water inlets 8. If too much cold water is injected into the water inlet cavity 14, it can flow out through the overflow holes 9 to the bottom of the heating basin 1. This ensures that the food container 7 is placed into the heating basin 1 first, and then water is added before use. This design avoids the need to add water first to react with the heating pack 10 before quickly placing the food container 7 and food into the heating bowl 1, thus improving the safety of using the heating bowl 1 and the food container 7. The water injection cavity 14 on the side wall of the heating bowl 1 is filled with cold water, which also prevents the side wall of the heating bowl 1 from overheating, further preventing burns to the user. Simultaneously, locking holes 12 are fixedly connected at the four corners of the limiting groove 11, and locking protrusions 13 are fixedly connected at the four corners of the heating pack 10. The locking holes 12 and locking protrusions 13 are interlocked, allowing the heating pack 10 to engage with the locking protrusions 13 within the locking holes 12 when it is positioned on the bottom side of the heating bowl 1 via the limiting groove 11. This improves the stability of the heating pack 10 within the limiting groove 11, facilitating even heating of the food inside the food container 7.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
