Description

Technical Field

[0001] This utility model relates to the field of convenience food, and in particular to a heating device and a self-heating instant beverage. Background Technology

[0002] Existing self-heating convenience foods typically use a self-heating pack immersed in room temperature water to heat the food with the generated steam (adding hot water could cause splashing and injury), which is not suitable for brewing beverages.

[0003] Currently, the main self-heating technology solutions for instant beverages on the market integrate the heating device with the container, such as self-heating cups for brewing tea or coffee. The drawbacks of this existing solution are: it is bulky and inconvenient to carry; as a disposable product, it incurs high transportation and material costs; and it generates a lot of waste after use.

[0004] Based on this, this application provides a heating device suitable for brewing beverages and a self-heating brewing beverage to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art. Therefore, the present invention provides a heating device suitable for brewing beverages and a self-heating brewing beverage.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] In a first aspect, a heating device is provided, comprising a housing and a self-heating pack disposed within the housing; the housing has a structure with a sealed bottom and an open top, with a plurality of inlet and outlet ports at the bottom and a telescopic cover sealed at the top; the interior of the housing is provided with a closed heating chamber above the inlet and outlet ports by a partition, the partition at the top of the heating chamber is provided with a water passage hole, and a water vapor channel connecting the inlet and outlet ports and the water passage hole is formed between the heating chamber and the housing, and the self-heating pack is disposed within the heating chamber.

[0008] In some alternative embodiments, the top partition of the heating chamber is configured as a concave structure in the middle, and the water passage is located in the middle of the partition.

[0009] In some alternative embodiments, a water-soluble film is provided inside the water passage.

[0010] In some optional embodiments, the inlet and outlet include a plurality of bottom holes provided on the bottom plate of the housing and a plurality of grid holes provided on the side wall of the housing.

[0011] In some alternative embodiments, the telescopic cover is bonded to the housing.

[0012] In some alternative embodiments, the housing is made of heat-resistant food-grade plastic or waterproof paper.

[0013] In some alternative embodiments, the telescopic cover is a folded film bag or a waterproof paper bag, wherein the film bag is made of high-temperature resistant food-grade plastic.

[0014] Secondly, a self-heating instant beverage is provided, comprising a beverage pack for brewing and the heating device, wherein the beverage pack is disposed within the housing of the heating device below the heating chamber.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The heating device is designed with a self-heating pack encapsulated inside the shell, allowing water of any temperature to be added directly to the container without the risk of hot water splashing and causing injury. Adding hot water can extend the time the water remains at a high temperature, making it especially suitable for cold climates.

[0017] 2. The heating device floats after generating steam, so there is no need to worry about excessive water filling or water overflowing from the heating chamber and contaminating the food. In addition, the center of gravity of the heating device is located in the lower middle part, so it will not tip over when floating in water.

[0018] 3. The self-heating instant beverage design combines the beverage pack with the heating device.

[0030] Example 1

[0031] This embodiment provides a heating device, as shown in the attached figure. Figure 1 As shown, it includes a housing 1, a telescopic cover 2, a heating chamber 3, and a self-heating pack 4, wherein:

[0032] The shell 1 has a structure with a sealed bottom and an open top, and its bottom is provided with a number of inlet and outlet ports 1.1; preferably, the inlet and outlet ports 1.1 include a number of bottom holes 1.1a provided on the bottom plate of the shell 1 and a number of grid holes 1.1b provided on the side wall of the shell 1; the shell 1 is made of high temperature resistant food-grade plastic or waterproof paper.

[0033] The telescopic cover 2 is fitted and glued to the top opening of the shell 1 to close the shell; preferably, the telescopic cover 2 is a folded film bag or waterproof paper bag, wherein the film bag is made of high-temperature resistant food-grade plastic.

[0034] The interior of the housing 1 is surrounded by a closed heating chamber 3 above the inlet / outlet 1.1 by a partition 1.2. The partition 1.2 at the top of the heating chamber 3 is provided with a water passage 1.2.1, and a water vapor channel 1.3 is formed between the heating chamber 3 and the housing 1, connecting the inlet / outlet 1.1 and the water passage 1.2.1.

[0035] The self-heating pack 4 is located inside the heating chamber 3. The size of the self-heating pack is determined according to the heat required to brew the food, and the shape is determined according to the spatial shape of the heating chamber, so that the self-heating pack is basically in contact with the inner wall of the heating chamber. At the same time, the heating chamber needs to leave a certain space for the self-heating pack to react and expand.

[0036] Preferably, the top partition 1.2 of the heating chamber 3 is designed with a concave shape in the middle, and the water passage 1.2.1 is located in the middle of the partition. Preferably, a water-soluble film 5 is provided inside the water passage 1.2.1. The water-soluble film 5 can be a starch film. The thicker the starch film, the slower the film is dissolved and penetrated. Therefore, the opening time of the water passage can be controlled by controlling the thickness of the starch film. It is usually designed to dissolve and penetrate in 15 to 20 seconds, during which time the user has generally completed the water filling operation.

[0037] Working Principle: The heating device is placed vertically into the brewing container. The beverage packet is then placed inside, and drinking water is poured in, ensuring the water level at least covers the top of the heating device. During this process, water enters the housing through the inlet and outlet. The air inside the housing cavity, under water pressure, causes the telescopic cover to expand, increasing the internal space of the housing cavity. The water level inside the cavity continues to rise until it exceeds the top partition of the heating chamber. At this point, the telescopic cover extends to its limit, and due to the compression of the air, it reaches equilibrium with the external water pressure, resulting in the highest water level inside the housing. Simultaneously, because the water level exceeds the top partition of the heating chamber, some water enters the concave structure of the top partition and slowly dissolves through the water-soluble film. Once the water-soluble film is dissolved, the water in the concave structure flows into the heating chamber. The amount of water flowing in is determined by the volume of the concave structure and can be designed according to the water requirements of the self-heating pack.

[0038] Upon immersion in water, the self-heating pack undergoes an exothermic reaction, generating a large amount of high-temperature steam. This steam accumulates, creating pressure that forces it out through the water inlet and outlet into the water within the container, thus heating the water and brewing the beverage packet. During this process, heat from the heating pack is also conducted to the water through the shell. Compared to steam heating, the self-heating pack's heat transfer process is more sustained, helping to maintain the beverage's temperature for an extended period. Once heating begins, the entire heating device floats on the beverage because the space inside the shell is filled with high-temperature steam. Since the heating device's center of gravity is located in the lower middle part, it remains upright while floating in the water, preventing it from tipping over. This effectively prevents residual solution from leaking into the beverage. Additionally, a partition prevents leakage of residual solution in case the heating device accidentally tilts. After the beverage is brewed, the floating heating device can be removed and discarded.

[0039] Example 2

[0040] This embodiment provides a self-heating instant beverage, as shown in the attached image. Figure 2 As shown, it includes a beverage pack 6 for brewing and a heating device as described in Embodiment 1. The beverage pack is disposed inside the housing 1 of the heating device and located below the heating chamber 3.

[0041] The self-heating beverage designed in this embodiment combines a beverage pack for brewing with a heating device. Compared with the first embodiment, this embodiment utilizes the high-temperature steam generated by the heating chamber to pass through the beverage pack and then enter the water, resulting in high heat exchange efficiency and faster and more thorough brewing.

[0042] Working Principle: The heating device is placed vertically into the brewing container, and drinking water is poured into the container, ensuring the water level at least covers the top of the heating device. During this process, water enters the shell through the inlet and outlet. The air inside the shell cavity, under water pressure, causes the telescopic cover to extend, expanding the internal space of the shell cavity. The water level inside the cavity continues to rise until it exceeds the top partition of the heating chamber. At this point, the telescopic cover extends to its limit, and due to the compression of the air, it reaches equilibrium with the external water pressure, resulting in the highest water level inside the shell. Simultaneously, because the water level exceeds the top partition of the heating chamber, some water enters the concave structure of the top partition and slowly dissolves through the water-soluble film. After the water-soluble film dissolves, the water in the concave structure flows into the heating chamber. The amount of water flowing in is determined by the volume of the concave structure and can be designed according to the water demand of the self-heating pack.

[0043] During this process, the internal air pressure of the device fluctuates. External water and internal high-temperature steam alternately enter the beverage pack, continuously exchanging heat within the pack and discharging the active ingredients into the water inside the container to create the beverage. Simultaneously, the heat from the self-heating pack is conducted to the water through the shell. Compared to steam heating, the self-heating pack's heat transfer process is more sustained, which helps maintain the beverage's temperature for a longer period. Once heating begins, the entire heating device floats on the beverage because the space inside the shell is filled with high-temperature steam. Since the heating device's center of gravity is located in the lower middle part, it remains upright while floating in the water, preventing it from tipping over. This effectively prevents residual solution from leaking into the beverage after the self-heating pack's reaction. Additionally, the partition prevents leakage of residual solution in case the heating device accidentally tilts. After the beverage is prepared, the floating heating device can be removed and discarded.

[0044] It is worth noting that: 1. The volume of the shell and the mass of the self-heating pack are adjusted to ensure that: during the water filling process, the heating device does not float before the water level inside the shell reaches the maximum level; when the maximum water level is reached inside the shell, water continues to be filled, and the heating device floats on the water surface (the extension of the telescopic cover increases buoyancy). After the heating reaction begins, a large amount of water vapor discharges the water in the steam channel, increasing the buoyancy of the heating device, thereby offsetting the increased mass of the self-heating pack due to water absorption, and maintaining the floating state of the heating device.

[0045] 2. The heating device can be designed in various shapes, such as a treasure chest, iceberg, swimming ring, or animal shape, after floating, making the device more beautiful and interesting.

[0046] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
