Description

Technical Field

[0001] This utility model relates to a portable, consumer-grade self-heating food device, belonging to the technical field of food heating appliances for consumers. Background Technology

[0002] Self-heating food containers, or self-heating pots, are appliances used for quickly heating food. They have a built-in heat source, are portable, and can solve the problem of dining in the wild or other specific environments. The heat source of self-heating pots generally uses chemical reagents. Water is added during use, and the heat generated through a chemical reaction heats the food, ultimately cooking it. Compared to compressed gas cylinders or alcohol gel heating, chemical heating methods do not involve open flames, eliminating the risk of fire. The products have a high safety level during both transportation and use. Self-heating pots have a wide range of applications, including mountainous areas, parks, earthquake and mudslide disaster areas, flood-affected areas, and areas with water supply disruptions. They can also replace open flames in hot pot restaurants, preventing fires and ensuring public safety in densely populated areas. Despite these advantages, self-heating pots require users to add water to initiate the chemical reaction. In mountainous or forested environments, when users do not have enough water and there are no nearby water sources, they often need to walk longer distances to find water, which can delay their meals. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a water-storage self-heating food box that does not rely on external water supply and can simultaneously add water to both the food cavity and the heating cavity to quickly cook food and meet the user's need for dining anytime, anywhere.

[0004] This utility model provides a water-storage self-heating food box, including a food cavity and a heating cavity fixed at the lower part of the food cavity, and also includes a water storage cavity. The water storage cavity is connected to a water inlet pipe. The water inlet pipe is connected to a first branch pipe and a second branch pipe. The end of the first branch pipe is connected to the food cavity, and the end of the second branch pipe is connected to the heating cavity. A synchronous water injection mechanism is sleeved inside the water inlet pipe. When the synchronous water injection mechanism is in operation, it controls the water flowing out of the water storage cavity to simultaneously enter the food cavity and the heating cavity.

[0005] Furthermore, the synchronous water injection mechanism includes a piston rod, which is hollow and sleeved inside the water inlet pipe. The piston rod has a first through hole and a second through hole perpendicular to the piston rod's pushing direction. In the working state, the first through hole is connected to the food cavity, while the second through hole is connected to the heating cavity.

[0006] Furthermore, the water inlet pipe has a side hole that is connected to the water outlet of the water storage chamber, and the piston rod has a water inlet hole that is connected to the side hole in the working state.

[0007] Furthermore, the outer side of the food cavity is sealed with a thin film, and the end of the piston rod is pointed to pierce the thin film.

[0008] Furthermore, the inner sidewall of the food cavity is movably connected to a float block that can block the first branch pipe by the buoyancy of the water in the food cavity.

[0009] Furthermore, the float is slidably connected to the chute, which is fixed to the inner wall of the food cavity. The cross-section of the chute is two L-shaped structures arranged opposite each other. In the working state, when the water level in the food cavity rises to a predetermined target value, the float floats up and blocks the lower end of the first through hole.

[0010] Furthermore, the water storage cavity is annular and fixed above the heating cavity.

[0011] Furthermore, the water storage cavity is provided with an annular cover, which engages with the annular groove on the water storage cavity via an annular protrusion on the bottom surface.

[0012] Furthermore, a shell is fixedly connected to the outside of the heating cavity, and a heat insulation layer is fixed to the inside of the shell.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. A water storage structure is set up to store water, which is convenient for users to use in outdoor environments where there is no water source. The water storage structure fills the inner cavity with water through the water inlet pipe, without the need to disassemble the heating chamber to add water. The operation is simple and meets the user's dining needs anytime and anywhere.

[0015] 2. The synchronous water injection mechanism inside the water inlet pipe allows water to be simultaneously injected into the food cavity and heating cavity via one and two pipes. Compared to traditional self-heating pots, it eliminates the need to disassemble the structure to add water to the food cavity and then to the heating cavity separately, making water addition faster and more convenient than traditional products. The synchronous water injection mechanism has low manufacturing costs and is easy to mass-produce.

[0016] 3. The central area of ​​the annular water storage chamber, located above the lid of the food chamber, can hold tableware such as chopsticks, as well as emergency supplies such as flashlights and medicines, making it suitable for outdoor emergencies or disaster relief.

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Other solutions obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the protection scope of this utility model.

[0027] like Figures 1 to 5As shown in the figure, a water-storage self-heating food box according to an embodiment of the present invention includes a food cavity 1 and a heating cavity 2 fixed to the lower part of the food cavity 1, and also includes a water storage cavity 3. The water storage cavity 3 is connected to a water inlet pipe 4. The water inlet pipe 4 is connected to a first branch pipe 5 and a second branch pipe 6. A first cavity hole 102 is opened on the upper side of the food cavity 1. The end of the first branch pipe 5 is connected to the food cavity 1 through the first cavity hole 102. A second cavity hole 201 is opened on the upper side of the second branch pipe 6. The end of the second branch pipe 6 is connected to the heating cavity 2. The second branch pipe 6 is connected to the water inlet pipe 4 through the second cavity hole 201. A synchronous water injection mechanism 7 is sleeved inside the water inlet pipe 4. When the synchronous water injection mechanism 7 is in working state, it controls the water flowing out of the water storage cavity 3 to simultaneously enter the food cavity 1 and the heating cavity 2. The synchronous water injection mechanism 7 includes a piston rod 701, which is hollow and sleeved inside the water inlet pipe 4. The piston rod 701 has a first through hole 702 and a second through hole 703 perpendicular to its thrust direction. In operation, the first through hole 702 communicates with the food cavity 1, while the second through hole 703 communicates with the heating cavity 2. The first branch pipe 5 and the second branch pipe 6 can be integrally formed with the water inlet pipe 4, or they can be processed in sections and then assembled together. The piston rod 701 can be cylindrical or square. The cross-sections of the first through hole 702 and the second through hole 703 are both smaller than the cross-section of the side hole 401 to ensure a stable water flow.

[0028] The water inlet pipe 4 has a side hole 401, which connects to the outlet 301 of the water storage chamber 3. The piston rod 701 has a water inlet hole 704. In the working state, the water inlet hole 704 connects to the side hole 401. At this time, the first through hole 702 connects to the food chamber 1, and the second through hole 703 connects to the heating chamber 2 via the second cavity hole 201. Water flowing out of the water storage chamber 3 flows downward into the food chamber 1 and the heating chamber 2. In the default state, the water inlet hole 704 and the side hole 401 are completely misaligned, and water will not flow downward from the water storage chamber 3. When in use, the piston rod 701 is pushed to align the water inlet hole 704 with the side hole 401.

[0029] Preferably, the outer side of the food cavity 1 is sealed with a thin film to ensure that the food cavity 1 is dry and clean. The piston rod 701 has a pointed end. When the piston rod 701 is pushed forward, the end of the piston rod 701 can pierce the thin film and pass through the first cavity hole 102, which facilitates the addition of water to the food cavity 1. A limiting plate 705 is fixed to one end of the piston rod 701 facing the outside of the housing 9. The limiting plate 705 is fixedly connected to the end of the push-pull rod 706.

[0030] like Figure 7As shown, a float 8 is movably connected to the inner wall of the food cavity 1, capable of blocking the first branch pipe 5 by the buoyancy of the water in the food cavity 1. The float 8 is slidably connected in the slide groove 103, which is fixed to the inner wall of the food cavity 1. The upper end of the slide groove 103 is directly opposite the position of the first cavity hole 102. The upper shape of the float 8 is adapted to the shape of the first through hole 702. The cross-section of the slide groove 103 is two L-shaped structures arranged opposite each other, which hold the float 8 in place and prevent the float 8 from drifting horizontally and falling out of the slide groove 103. In operation, the piston rod 701 extends from the first cavity hole 102. When the piston rod 701 is pushed to the bottom, it is restricted by the limiting plate 705. At this time, the first through hole 702 is located directly above the slide groove 103. When the water level in the food cavity 1 rises to the predetermined target value, the float 8 floats up in the slide groove 103 with the water level and blocks the lower end of the first through hole 702. The first branch pipe 5 stops adding water to the food cavity 1, which can prevent the food cavity 1 from overflowing due to excessive water or the food from becoming bland due to excessive water.

[0031] As an optional implementation, the water storage chamber 3 is annular and fixed above the heating chamber 2. The water storage chamber 3 is equipped with a ring cover 302, which engages with an annular groove 304 on the water storage chamber 3 via an annular protrusion 303 on its bottom surface. A sealing rubber strip is fixed to the bottom of the groove or to the position adjacent to the protrusion on the bottom surface of the ring cover 302. The water storage chamber 3 can be used to directly store water, or multiple arc-shaped bags can be used to fill the water, which are then placed inside the water storage chamber 3. When in use, the opening of the arc-shaped bags is unscrewed to pour the water into the water storage chamber 3. In situations of water shortage during disaster relief or outdoor hiking, excess water in the arc-shaped bags can be used as emergency drinking water. Multiple compartments can be set in the middle area of ​​the annular water storage chamber 3, above the food cover 101, to store chopsticks and other tableware, as well as emergency supplies such as flashlights and medicines, suitable for use in outdoor emergencies.

[0032] A shell 9 is fixedly connected to the outside of the heating chamber 2. A heat insulation layer is fixed to the inside of the shell 9. The heat insulation layer can be made of clay, foam insulation material, etc., which can prevent the outer shell from getting too hot during use and also provide a certain heat insulation for the inner cavity.

[0033] like Figure 5 and Figure 6As shown, during use, the piston rod 701 is first pushed, and the piston rod 701 moves forward. The pointed end of the piston rod 701 pierces the film on the outside of the food cavity 1 and then passes through the first cavity hole 102. At this time, the front end of the piston rod 701 is deeply inserted into the food cavity 1. Then, adjust the position of the piston rod 701 so that the water inlet 704 is aligned with the side hole 401 of the water inlet pipe 4. In this state, the first through hole 702 is connected to the food cavity 1, and the second through hole 703 is connected to the heating cavity 2. Water in the water storage cavity 3 flows downward from the outlet 301, enters the piston rod 701 through the water inlet 704, and then part of it flows into the food cavity 1 through the first through hole 702, while the other part flows into the heating cavity 2 through the second through hole 703, thus simultaneously adding water to the food cavity 1 and the heating cavity 2. After adding a certain amount of water, pull the piston rod 701 in the opposite direction, causing the water inlet 704 to be misaligned with the side hole 401 of the water inlet pipe 4, and the bottom of the water storage cavity 3 is closed, thereby stopping the addition of water to the food cavity 1 and the heating cavity 2. The water flowing into the heating cavity 2 reacts chemically with the heating reagent in the heating cavity 2 to generate heat energy, cooking the food in the upper food cavity 1. The heating reagent can be a commercially available quicklime or similar material package.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various combinations, substitutions and modifications can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
