(A)

Referring to fig. 1 to 5, the portable self-heating device according to the present invention can separate the heat source 5 from the heated object 4 during the heating process, and form a reusable portable heating structure, and keep the temperature during and after the heating process. Accordingly, in a preferred embodiment, the portable self-heating device consists essentially of: the container comprises a container body 1, a container cover 2, a heat source body 5 and a reaction liquid 7, wherein the container cover 2 is preferably matched and connected with the container body 1 in a threaded connection mode in the embodiment so as to cover the container body 1 and define a heating cavity in the container body 1.

Meanwhile, in order to separate the heated object 4 and the heat source body 5 in the heating chamber, a support member 3 is provided at an inner wall of the container body 1 to support the heated object 4 to be suspended in the heating chamber, thereby defining a heat source region 12 and a heating region 11, and the heat source body 5 is accommodated in the heat source region 12, and the reaction liquid 7 is filled in the heating chamber to react with the heat source body 5.

It is worth mentioning that, in this embodiment, the supporting member 3 does not completely support the object 4, but at least three points of support relationship are formed by the object 4 itself, the inner wall of the container body 1 and the supporting member 3, so as to construct a stable support relationship, for example, the bottom of the object 4 is supported by the supporting member 3, and the object 4 itself can lean against the inner wall of the container body 1 to form at least two support points, so that under the support structure, the supporting member 3 can be designed into a smaller boss structure, so as to enlarge the area of the communication between the heat source region 12 and the heating region 11 as much as possible, thereby reducing the obstruction when putting in/taking out the heat source 5, on the other hand, reducing the shielding of the heat source region 12, and improving the efficiency of the heat source region 12 to introduce heat into the heating region 11.

For example, in one embodiment, the reaction liquid 7 may be water, the heat source body 5 may be a lime heating bag, and then a proper amount of the reaction liquid 7 is filled into the heat source zone 12, and reacts with the heat source body 5 to form steam, and during the steam rises to the heating zone 11, the steam flow is increased by reducing the shielding, so that the heating effect is improved, and the heat loss is reduced.

For example, in another embodiment, the reaction liquid 7 may be water, the heat source 5 may be a lime heating bag, and at this time, an appropriate amount of the reaction liquid 7 is filled into the heating area 11, and can react with the heat source 5 and form boiling heating for the heated object 4, and when the reaction liquid 7 serves as a heat transfer medium, shielding reduction can improve the heat transfer efficiency of the heat transfer medium, thereby improving the heating effect and reducing heat loss.

In addition, in a preferred embodiment, in order to facilitate replacement of the heat source 5, a tether 6 may be provided to the heat source 5 so that the heat source can be taken out of the container body 1 by pulling and the reaction solution 7 can be separated to provide a draining effect.

Meanwhile, in order to avoid the loss when the container cover 2 is separated from the container body 1, in a preferred embodiment, a connecting member 9 can be arranged between the container cover 2 and the container body 1, so that the container cover 2 and the container body 1 are bound to avoid the loss.

In another preferred embodiment, in order to better anchor the heat source body 5 and prevent the tether 6 from falling into the heating cavity together by accident, the support member 3 is preferably formed by recessing the sidewall of the container body 1 to form a convex shape at the inner wall of the container body 1 and recessing the wire groove portion 32 at the outer wall thereof, so that two functional portions are defined by a structural change, and the tether 6 on the heat source body 5 can be easily removed by being sleeved at the wire groove portion 32 to anchor the movement limit of the heat source body 5 on the container body 1 and binding the position of the tether 6 to facilitate the removal/release of the heat source body 5.

On the other hand, since the thermal reaction between the heat source body 5 and the reaction liquid 7 generates water vapor, which causes a rise in the internal pressure of the heating chamber and thus poses a safety hazard, in a preferred embodiment, the portable self-heating apparatus further comprises: a venting module 8 connected to the container lid 2 and communicating with the heating chamber for venting the exhaust gas, wherein the venting module 8 comprises: an air pipe 81 and an air plug 86, wherein the air pipe 81 is arranged on the container cover 2 and is communicated with the heating cavity, and the air plug 86 opens/closes an air outlet of the air pipe 81 at proper time.

Wherein in order to further pin the moisture content in the heating chamber, avoid moisture content to run off the overspeed because of steam drives, form similar empty fever state, ventilate module 8 in this embodiment still includes: a gas-liquid separating member 85, wherein the gas-liquid separating member 85 is disposed at the first position of the gas pipe 81, and the gas-liquid separating member 85 is preferably made of a material or a structure, such as a capillary array, a hydrophobic sponge, etc., through which gas easily penetrates and liquid does not easily penetrate, thereby retaining water and discharging internal pressure.

On the other hand, in order to control the internal pressure of the heating chamber to a certain extent and lock up a certain amount of steam heat source, and to control the amount of heat loss, in a possible preferred embodiment, as shown in fig. 11, the ventilation module 8 comprises: the gas pipe 81, the gas-liquid separation piece 85, the blocking plate 83, and the elastic piece 82 (such as a spring), wherein the gas pipe 81 is communicated with the heating chamber, the gas-liquid separation piece 85 is disposed at the first position of the gas pipe 81, the gas hole 84 is disposed on the pipe wall at the second position of the gas pipe 81, and the blocking plate 83 is connected with the gas pipe 81 through the elastic piece 82, so that the blocking plate 83 elastically seals the gas hole 84 at the second position of the gas pipe 81.

Therefore, when the internal pressure of the heating cavity reaches a certain degree, the blocking plate 83 is pushed away to release air pressure, and once the internal pressure of the heating cavity is stabilized within a preset range, the blocking plate 83 is driven by the elastic piece 82 to return, so that the heating cavity can be sealed, the internal liquid is prevented from seeping out, and the heating cavity is convenient to carry. It is noted that the control of the internal pressure of the heating chamber may be set according to the adjustment of the elastic force of the elastic member 82.

It should be noted that if the container lid 2 and the container body 1 are designed to withstand a certain pressure, the ventilation module 8 may not be provided, so that a pressure is formed in the heating chamber, and a hot working environment similar to that of a pressure cooker is created, thereby meeting the heating requirements of a wider variety of objects 4 to be heated.

It should be noted that, in this embodiment, the supporting member 3 on the loading frame 30 does not completely support the object 4 to be heated, but forms at least three-point supporting relation with the inner wall of the container body 1 and the supporting member 3 by the heated object 4 itself, thereby constructing a stable supporting relation, such as that the bottom of the heated object 4 is supported at least one supporting point by the supporting member 3, and the heated object 4 itself can form at least two support points against the inner wall of the container body 1, so that under the support structure, the supporting member 3 can be designed to be a small boss structure, so that the area of the communication part between the heat source region 12 and the heating region 11 can be enlarged as much as possible, thereby reducing the obstruction when the heat source body 5 is put in/taken out on one hand, reducing the shielding of the heat source region 12 on the other hand, and improving the efficiency of leading heat from the heat source region 12 to the heating region 11.

It should be noted that the above situations are all defined by the spatial division of the heating region 11 and the heat source region 12 in the present embodiment, and the fundamental principles and the main features of the present invention are not violated. Therefore, absolute isolation of the two is not critical in practical implementation. It can be seen that the present invention can be adjusted to the treatment of the object 4 with different volume forms according to the actual situation, and is within the scope of the disclosure of the present embodiment as long as the basic principle and the main features of the present invention are not violated.
