Immersion type self-heating device and kettle made of same

Technical Field

The utility model relates to the technical field of self-heating, in particular to an immersion type self-heating device and a kettle made of the same.

Background

Along with the change of seasons, in cold winter, bottled water, canned beverages, food and the like purchased by people are easy to stimulate intestines and stomach to generate uncomfortable feeling due to low temperature when being eaten. However, it is difficult to heat beverages and foods in an outdoor environment where there is no fire source or power source. The heating bag made of lime powder and other substances can react chemically with water to release heat, thereby providing a new heat source. With such heat sources, the skilled person has proposed many disposable self-heating solutions.

In order to fully exert the chemical efficiency of the heat generating powder and release the maximum amount of heat, it is necessary to provide a non-compressed space for the heat generating pack in the self-heating apparatus so that it can be sufficiently mixed with the reaction liquid and freely expand the volume. On the other hand, the heat generating pack is relatively hot when an exothermic reaction occurs, and if the heated food/drink is in direct contact with the heat generating pack, the packaging material of the heated food/drink may be deformed to be damaged or even a harmful chemical reaction occurs, and therefore, it is necessary to take measures to separate the heated food/drink from the heat generating pack from the viewpoint of safety in use.

As is well known, the application environment of the self-heating technology is mainly outdoors, and the outdoor application environment is divided into a static application environment and a dynamic application environment. Static application environments and dynamic application environments have significant application requirement differences. The self-heating device in the prior art mainly considers a static application environment and has poor applicability to a dynamic application environment. In the case of hiking behavior, the dynamic application environment needs to consider the volume and weight load of the self-heating product, the operability during walking, the versatility of the heated product (i.e., the versatility of the product), and other problems.

At present, the existing self-heating device mainly has the following defects:

(1) is a disposable product, has large volume and is inconvenient to carry and operate.

(2) In the dynamic application environment, the heating device has shaking vibration with a certain amplitude, and the problem of reaction liquid overflow is not considered, so that the carrying convenience is influenced, and the product practicability is obviously reduced.

(3) It is difficult to achieve convenient and safe pick-and-place and replacement of the heat generating pack for repeated heating in a dynamic application environment.

(4) It is difficult to achieve convenient eating or addition of heated food during heating in a dynamic application environment.

(5) The quantity of reaction liquid used for one time is large, the problem of storage and reutilization of residual water in the previous time is not considered, a plurality of water bags need to be carried, and more weight is increased.

(6) The heating cabin is arranged at a position where the hand is easy to touch, and the hand is easy to scald when being held.

As shown in fig. 1 to 7, the present invention provides an immersion type self-heating apparatus for use in a dynamic application environment. The immersion type self-heating apparatus includes: a container body 3, a container cover 4, a heating compartment 1 and a heating compartment cover 2. The heating compartment 1 is a cavity integrally formed on the container cover, with an opening facing upward and protruding downward relative to the back of the container cover. The heating cabin 1 can contain a reaction liquid 7 and a heating bag 5. The container body 3 can contain food to be heated. After the container lid 4 is fastened to the container body 3, the heating compartment 1 is accommodated in the container body 3 and can be partially or entirely immersed in the food to be heated to heat it. When the heating compartment is used, the process of buckling the container body and the corresponding cover body is the process of connecting the heating compartment and the container body into a whole, and is also the process of immersing the heating compartment into food in the container body. The heating of the heated food is stopped when the container cover is opened, and then the container body can be inclined to enable the food to flow into the opening, and the heated food can be drunk as if a cup is taken for drinking water at ordinary times. In addition, at any time in the heating use process, the heating cabin cover is opened to take and place the heating bag and/or supplement the reaction liquid, and the operation is simple, convenient, safe and reliable.

In a specific embodiment of the present invention, the heating compartment 1 may be provided as a cylinder extending in the axial direction of the container body 3. The cross-sectional shape of the heating compartment 1 may be one of a triangle, a quadrangle, a polygon, a circle, or an ellipse. As shown in fig. 2, the heating compartment 1 has a rectangular cross-sectional shape.

The heating chamber 1 is used for accommodating the heating bag 5 and the reaction liquid 7, and is a space where chemical reaction occurs to release heat. The heat generating pack 5 is a substance that generates a chemical reaction to release heat after being mixed with the reaction solution, and is usually packaged with a nonwoven fabric. The reaction solution 7 is a substance that can be mixed with the heat generating pack to cause a chemical reaction and release heat, and has good thermal conductivity. Tap water is preferably used. The reaction solution 7 of the present invention contains a reaction solution in a liquid state and a vapor state. In addition, the heating chamber 1 may serve as a storage container for the reaction solution. After each heating, only the heating bag is taken out of the heating chamber, and the rest of the reaction liquid can be still stored in the heating chamber. Therefore, when the heating cabin cover is used next time, the heating cabin cover is opened, and the heating bag is placed in the heating cabin cover to generate chemical reaction and release heat. The immersion type self-heating device can obviously reduce the carrying amount of the reaction liquid, only needs to supplement the reaction liquid in time after being used for many times, simplifies the operation and is beneficial to being used in a dynamic application environment.

The container body 3 is used for containing heated food. The side walls and the bottom wall of the heating compartment 1 are formed as enclosing members 9. The heated food 6 in the container body 3 is in direct contact with the enclosing member 9 of the heating compartment 1. When the food heating device is used, the reaction liquid 7 receives heat released by the heat receiving bag 5, the heat is conducted to the enclosing member 9, and the heated food 6 absorbs the heat from the enclosing member 9. In order to improve the heat conduction performance of the heating compartment 1, as shown in fig. 1 and 2, the submerged self-heating apparatus of the present invention further includes heat conduction fins 10. Preferably, the heat conducting fins 10 may be disposed on the bottom side wall of the heating compartment 1 at even intervals in the circumferential direction, and formed in a sheet structure extending in the horizontal direction and disposed vertically.

In order to release the gases produced by the chemical reaction, the heating hatch 2 is provided with a ventilation portion 8 communicating with the heating compartment 1. In one embodiment, vent 8 includes a vent tube 81 formed in heated hatch 2 and a rubber plug 82 connected to vent tube 81 and used to plug the vent tube. In addition, a hole can be formed at a suitable position of the heating chamber 1 or the heating chamber cover 2 to serve as the ventilation part 8, a rubber plug is used for sealing the ventilation part 8, and the rubber plug is pulled out at a proper time in the using process to release gas. In another embodiment, the ventilation part 8 is a one-way valve that can be automatically opened or closed according to the pressure of the gas in the heating chamber 1. Thus, when the gas pressure in the heating chamber 1 reaches a preset value, the pressure forces the one-way valve to automatically open, and the gas circulation channel is opened to realize gas release. When the pressure value in the heating chamber 1 is smaller than a preset value, the check valve is automatically closed, and the passage for gas circulation is closed. In addition, an air flow channel naturally formed at the interface when the heating chamber 1 and the heating chamber cover 2 are not tightly buckled can be used as the ventilation part 8.

In order to better adapt to dynamic application environment, the ventilation part 8 should be optimally designed to realize the effect of not easily leaking the reaction liquid when opening. Specifically, the opening of the vent part 8 should be as small as possible and should be a certain distance above the liquid surface of the reaction solution. In addition, in order to prevent the reaction liquid from flowing into the ventilating part, the immersion type self-heating device further comprises a blocking member arranged in the ventilating part, and the blocking member can be sponge which can penetrate gas and can not penetrate liquid easily.

The utility model can ensure the immersion type self-heating device to have good sealing performance by respectively arranging the cover body structures on the container body 3 and the heating cabin 1, namely the container cover 4 and the heating cabin cover 2, and is convenient to use in a dynamic application environment. Specifically, in the first embodiment, as shown in fig. 6, an annular wall is formed at the opening of the heating compartment 1 to be higher than the upper surface of the container cover 4, and a first connecting portion is formed on the annular wall. The heating hatch 2 is formed with a second connecting portion, and the first connecting portion and the second connecting portion are mutually reverse-rotation threads. In the second embodiment, as shown in fig. 8, an annular wall is formed at the edge of the container cover 4 to be higher than the upper surface of the container cover 4, and a first connecting portion is formed on the annular wall. The heating hatch 2 is formed with a second connecting portion, and the first connecting portion and the second connecting portion are mutually reverse-rotation threads. Thus, the heating cabin cover 2 is matched with the heating cabin 1, and the heating cabin cover and the heating cabin 1 have good sealing performance after being buckled, so that the immersion type self-heating device can be ensured not to leak reaction liquid 7. The container cover 4 is matched with the container body 3, and the container cover and the container body 3 have good sealing performance after being buckled, so that the immersed self-heating device can be ensured not to leak heated food 6.

The manner of using the submerged self-heating apparatus will be briefly described, and as shown in fig. 1 to 8, the reaction solution 7 is contained in the heating chamber 1 in the initial state. The heating compartment 1 is part of a container lid 4. After the heating compartment cover 2 is opened, the heating bag 5 can be placed in the heating compartment 1, after the container cover 4 is opened, the heated food 6 can be placed in the container body 3, and after the container cover 4 is buckled with the container body 3, the heating compartment 1 is immersed in the heated food 6. It can be seen that the removal of the heat pack 5 and/or the pouring of the reaction liquid 7 into the heating compartment 1 and the removal of the heated food 6 from (into) the container body 3 are two separate events, which do not affect each other. During heating, the ventilation part 8 can be opened after the heating cabin cover 2 and the heating cabin 1 are buckled. The heating hatch 2 can be opened to take out the hot pack 5 with the container lid 4 closed. When the heated food 6 is stored in the container body 3, the heated food 6 and the reaction liquid 7 can be carried along after the heating hatch 2 and the container cover 4 are fastened and the ventilation part 8 is closed.
