Description

Technical Field

[0001] This utility model relates to the field of self-heating bowl technology, and more specifically, to a water storage structure for a self-heating bowl and the self-heating bowl itself. Background Technology

[0002] Most existing self-heating bowl structures, such as the self-heating food box disclosed in Chinese patent CN222656467U, involve a water storage cavity extending vertically inward from the bottom of the main body, with the port end face of the water storage cavity sealed with a thin film. Rotating the bottom cover punctures the film, allowing water from the storage cavity to flow into the bottom cover and react with the heating pack. In this type of design, the water storage cavity is integrated into the main body, requiring its material and appearance to match, resulting in high costs. This also means that when the main body changes color or shape, the water storage cavity must also be modified, leading to poor compatibility. Furthermore, the water storage cavity occupies a significant amount of space within the main body, severely restricting the shape of the bowl used to hold food, further contributing to the poor compatibility of the main body. Utility Model Content

[0003] This utility model discloses a water storage structure for a self-heating bowl, aiming to improve the problems of low compatibility and high cost of existing self-heating bowl water storage structures.

[0004] The present invention adopts the following solution:

[0005] A water storage structure for a self-heating bowl for supplying water to a heating pack located in a lower housing includes a water storage component fitted inside the self-heating bowl and detachably connected to the bottom of an upper housing. The water storage component has a water storage cavity, an inlet communicating with the water storage cavity, and at least one outlet. The inlet is sealed by a first seal, and the outlet is provided with a second seal. The water storage structure is configured such that when the lower housing rotates relative to the upper housing, a peeling portion of the lower housing peels the second seal from the outlet, allowing water in the water storage cavity to flow into the lower housing.

[0006] As a further improvement, the water storage component is arranged in a ring shape, and the water storage cavity is similar in shape to the water storage component.

[0007] As a further improvement, the water inlet is located at the top of the water storage component, the water outlet is located at the bottom of the water storage component, the first sealing element is a thin film, and the second sealing element is a sealing plug.

[0008] As a further improvement, a stop portion for limiting the sealing plug is provided on both sides of the outlet.

[0009] As a further improvement, the bottom surface of the water storage chamber is inclined, and at least one water outlet is located at the lowest point of the bottom surface.

[0010] As a further improvement, the bottom of the water storage component is provided with two water outlets at different heights, and the lower housing has abutment parts that correspond one-to-one with the two water outlets. The two abutment parts are at different heights to abut against the second sealing element on the corresponding water outlet.

[0011] As a further improvement, the bottom surface of the water storage component is provided with a positioning part, which is used to align with the latch of the upper housing during assembly so that the two abutting parts are aligned with the corresponding water outlets.

[0012] As a further improvement, a first assembly part is provided on the outer wall of the water storage component, and a second assembly part is provided on the inner wall of the upper shell. The first assembly part and the second assembly part are engaged to limit the position of the water storage component.

[0013] As a further improvement, the stripping part is located on the inner bottom surface of the lower housing and is configured as a plate extending along the diameter direction of the lower housing.

[0014] Another self-heating bowl is provided, comprising a bowl body, a lid, an upper shell, a lower shell, and a water storage structure as described in any of the preceding self-heating bowls. The bowl body is suspended inside the upper shell for holding food. The top end of the upper shell is connected to the lid, and its bottom end is connected to the lower shell. The water storage component is detachably disposed at the bottom of the upper shell. The lower shell is operably driven to rotate relative to the upper shell, causing the second seal on the water storage component to detach from the water outlet, allowing water to flow into the lower shell and react with the heating pack, thereby heating the food inside the bowl.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0016] 1. The water storage component of this application is located inside the self-heating bowl and is detachably connected to the upper shell, making the water storage component an independent part that can be produced independently. This facilitates the storage and management of the water storage component, allowing for mass production before assembly with the upper shell. Furthermore, the structure is simple, with few parts, and is unaffected by changes in appearance. Changes in the color or appearance of either the upper or lower shell have no impact on the water storage component, resulting in high compatibility. In addition, since the water storage component is located inside the self-heating bowl, its material requirements can be lowered; recycled or mixed-color materials can be used, reducing the cost of the self-heating bowl. Positioning the water storage component at the bottom of the upper shell reduces the space occupied by the water storage cavity, allowing the upper shell to adapt to bowls of different shapes, improving its compatibility and further reducing costs.

[0017] 2. The bottom of the water storage chamber is inclined so that the water flow in the water storage chamber can be gathered at the lowest point of the outlet, ensuring that the water flow in the water storage chamber can be fully drained and improving the utilization rate of the water flow.

[0018] 3. The abutment part ensures the sealing of the second seal during transportation. The two outlets are at different heights, and can only be installed when aligned with the corresponding abutment part, thus avoiding misinstallation.

[0019] 4. The peeling part is located on the inner bottom surface of the lower housing and is configured as a plate extending along the diameter direction of the lower housing to ensure the area of ​​the peeling part acting on the second seal during rotation, thus ensuring rapid peeling.

The terms “first,” “second,” etc., are only used to distinguish different objects and should not be construed as indicating or implying relative importance or the quantity, specific order, or primary or secondary relationship of the indicated technical features. The term “several” means one or more, and “multiple” means two or more, unless otherwise explicitly specified. Example

[0035] Combination Figures 1 to 10This embodiment provides a water storage structure for a self-heating bowl to supply water to a heating pack located in the lower shell 3. The water storage component 1 is sleeved inside the self-heating bowl and detachably connected to the bottom of the upper shell 2. Specifically, the water storage component 1 has a water storage cavity 11 and a water inlet 12 and at least one water outlet 13 communicating with the water storage cavity 11. The water inlet 12 is sealed by a first sealing member, and a second sealing member 131 is disposed on the water outlet 13. The water storage structure is configured such that when the lower shell 3 rotates relative to the upper shell 2, the peeling part 31 of the lower shell 3 peels the second sealing member 131 from the water outlet 13, so that water in the water storage cavity 11 flows into the lower shell 3.

[0036] It should be noted that in this embodiment, the water storage component 1 is located inside the self-heating bowl and is detachably connected to the upper shell 2, making the water storage component 1 an independent part that can be produced independently. This facilitates the storage and management of the water storage component 1, allowing for mass production before assembling it with the upper shell 2. Furthermore, the structure is simple, with few parts, and is not affected by external appearance. Changes in the color or appearance of either the upper shell 2 or the lower shell 3 have no impact on the water storage component 1, thus ensuring high compatibility. In addition, since the water storage component 1 is located inside the self-heating bowl, its material requirements can be lowered; recycled materials or mixed-color materials can be used, reducing the cost of the self-heating bowl. The water storage component 1 is positioned at the bottom of the upper shell 2, reducing the space occupied by the water storage cavity 11 on the upper shell 2. This allows the upper shell 2 to adapt to bowls of different shapes, improving its compatibility and further reducing costs.

[0037] In a preferred embodiment, the water storage component 1 is arranged in a ring shape, and the water storage cavity 11 is similarly shaped to the water storage component 1, making the space arrangement inside the self-heating bowl more reasonable and compact. The heating pack inside the lower shell 3 can directly heat the bowl body when heating, ensuring heating efficiency.

[0038] Furthermore, the water inlet 12 is located at the top of the water storage component 1, and the water outlet 13 is located at the bottom of the water storage component 1. The first sealing element is a thin film, which can be tin foil or the like, sealed by heat shrinking. The second sealing element 131 is a sealing plug, preferably made of rubber or silicone. During installation, it can be directly inserted into the water outlet 13 to achieve a seal, which is convenient for disassembly and assembly, facilitates production, and ensures a smooth peeling process. Preferably, stop portions 132 are provided on both sides of the water outlet 13 to limit the sealing plug, so as to avoid the sealing plug deflecting during the peeling process and thus failing to peel off, and also to prevent the sealing plug from falling off due to shaking during transportation.

[0039] Based on the above embodiments, in an optional embodiment of this utility model, the bottom surface of the water storage cavity 11 is inclined, and at least one outlet 13 is located at the lowest point of the bottom surface, so that the water flow in the water storage cavity 11 can converge at the outlet 13 at the lowest point, ensuring that the water flow in the water storage cavity 11 can be fully drained and improving the utilization rate of the water flow. For example, the bottom of the water storage component 1 is provided with two outlets 13 at different heights, one outlet 13 is located at the highest position of the bottom, and the other is located at the lowest position of the bottom. When the second seal 131 is peeled off, the outlet 13 located at the highest position can take in air to accelerate the drainage speed of the outlet 13 located at the lowest position. Further, the lower housing 3 has abutment portions 32 corresponding to the two outlets 13 one-to-one, and the two abutment portions 32 are at different heights to abut against the second seal 131 on the corresponding outlet 13. The abutment part 32 ensures the sealing of the second seal 131 during transportation. The two outlets 13 are at different heights, but the second seal 131 is the same, so that it can only be installed when it is aligned with the corresponding abutment part 32 during assembly, thus avoiding misinstallation.

[0040] Preferably, the bottom surface of the water storage component 1 is provided with a positioning part 14, which is used to align with the latch 21 of the upper housing 2 during assembly, so that the two abutting parts 32 are aligned with the corresponding water outlets 13. The positioning part 14 can be configured as a long strip protruding from the bottom surface of the water storage component 1. During assembly, after pointing the long strip to the position of the latch 21, the water storage component 1 is pressed into the upper housing 2. The upper housing 2 is provided with the latch 21, and the lower housing 3 is provided with a corresponding locking body 33. When the latch 21 and the locking body 33 are engaged, the two housings cannot rotate relative to each other. When heating is required, the latch 21 is opened, and the housing can be rotated to disengage the second sealing member 131 from the water outlet 13. The latch 21 and the locking body 33 can prevent accidental operation from causing the heating pack to heat up.

[0041] In another embodiment, a first mounting portion 15 is provided on the outer wall of the water storage component 1, and a second mounting portion 22 is provided on the inner wall of the upper housing 2. The first mounting portion 15 and the second mounting portion 22 engage to limit the position of the water storage component 1. For example, the first mounting portion 15 protrudes along the outer wall of the water storage component 1, and the second mounting portion 22 is a groove provided on the inner wall of the upper housing 2. The engaging arrangement facilitates the assembly and disassembly of the water storage component 1, which is beneficial for its assembly. In other embodiments, a snap-fit ​​structure may also be used, but it is not limited to this and is not specifically limited.

[0042] In other embodiments, the peeling portion 31 is disposed on the inner bottom surface of the lower housing 3 and is configured as a plate extending along the diameter direction of the lower housing 3 to ensure the area of ​​the peeling portion 31 acting on the second seal 131 during rotation, thereby ensuring rapid peeling. Preferably, reinforcing ribs 311 are provided on both sides of the peeling portion 31 to ensure the strength of the peeling portion 31.

[0043] This utility model also provides a self-heating bowl, including a bowl body, a lid 4, an upper shell 2, a lower shell 3, and a water storage structure as described in any of the above embodiments. The bowl body is suspended inside the upper shell 2 for holding food. The top end of the upper shell 2 is connected to the lid 4, and its bottom end is connected to the lower shell 3. A water storage component 1 is detachably disposed at the bottom of the upper shell 2. The lower shell 3 is operably driven to rotate relative to the upper shell 2, causing the second seal 131 on the water storage component 1 to detach from the water outlet 13. Water flows into the lower shell 3 and reacts with the heating pack, thereby heating the food inside the bowl. For example, the outer wall of the upper shell 2 is provided with an installation part 23 for connecting to the lower shell 3, and its inner wall is provided with a second assembly part 22 for connecting to the water storage component 1. During installation, the water storage component 1 is first inserted into the upper shell 2, then the lower shell 3 containing the heating pack is connected to the upper shell 2, then the bowl body is placed inside, and finally the lid 4 is disposed on the top of the upper shell 2. It should be mentioned that the connection structure between the bowl body, the lid body 4, and the lower shell 3 and the upper shell 2 is existing technology and will not be described in detail here.

[0044] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
