DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 3 The utility model provides a technical solution: a self-heating convenient box with an inner liner having a vent hole, comprising a lunch box 1, a bottom bracket 2, an inner bracket component 3 and a box cover 4. The bottom bracket 2 is arranged at the lower side of the lunch box 1, the inner bracket component 3 is nested and installed inside the lunch box 1, and the upper end of the lunch box 1 is nested and connected with the box cover 4. The lunch box 1 is composed of a main box body 11, an air outlet 12, an insulation block 13 and a convex ring 14. The lower end surface of the main box body 11 is provided with an air outlet 12, and the outer surface of the main box body 11 is provided with an air outlet 12. An insulating block 13 is arranged on the side, a convex ring 14 is arranged on the inner side of the main box body 11, the bottom support 2 is composed of a heating box 21, a support platform 22, an anti-overflow ring 23, a handle 24, a first reinforcing rib 25 and an insulating ring 26, a support platform 22 is arranged in the heating box 21, an anti-overflow ring 23 is fixed on the upper end surface of the heating box 21, the inner support assembly 3 is composed of a support plate 31, a conical hole 32, a second reinforcing rib 33 and an extension ring 34, and a conical hole 32 is arranged at the center of the support plate 31.

[0020] The main box body 11 is in contact with the support 22, and the outer side of the main box body 11 is in contact with the heating box 21 to achieve a limiting effect. The main box body 11 is also evenly provided with air outlet holes 12, and the dispersed diameter of the air outlet holes 12 is smaller than the inner diameter of the support 22. When the main box body 11 and the heating box 21 are assembled, the support 22 can achieve a lifting effect on the main box body 11. With the help of the heating box 21 to limit the main box body 11, the main box body 11 can be prevented from shaking left and right, and the stability of the main box body 11 can be ensured. The design of the air outlet holes 12 can facilitate the high-temperature steam generated in the heating box 21 to enter the main box body 11 to achieve the effect of heating food.

[0021] The heat insulation blocks 13 are distributed at equal angles on the main box body 11, and the heat insulation blocks 13 can be square, strip or trapezoidal structures. Through the above structure, deformation and damage of the main box body 11 can be avoided, and burns to the user can be avoided, thereby ensuring the safety of the device.

[0022] The outside of the heating box 21 is also provided with first reinforcing ribs 25 evenly distributed at an angle, and a heat-insulating ring 26 is also fixed to the lower end surface of the heating box 21; a handle 24 is also fixed symmetrically on the anti-overflow ring 23, and the anti-overflow ring 23 and the handle 24 are an integrated structure. The first reinforcing ribs 25 can prevent the heating box 21 from being deformed and damaged, and the handle 24 can be used to facilitate the user to take it and avoid burns. In combination with the heat-insulating ring 26, damage to the desktop can be avoided during heating.

[0023] A second reinforcing rib 33 is fixed at an equal angle inside the support plate 31, and the height of the support plate 31 is less than the distance from the convex ring 14 to the lower end surface of the main box body 11; an extension ring 34 is also fixed to the outside of the support plate 31, and the extension ring 34 contacts with the convex ring 14 to achieve a positioning effect. The second reinforcing rib 33 can prevent the support plate 31 from being deformed and damaged. By cooperating with the extension ring 34 and the convex ring 14, the installation position of the second reinforcing rib 33 can be limited. By limiting the size of the support plate 31, it can be avoided that the support plate 31 blocks the normal air outlet of the air outlet 12, thereby ensuring normal heating.

[0024] Working principle: When using the self-heating convenience box with air holes in the inner liner, Figure 1-Figure 3 As shown, first put the heating bag into the heating box 21, and add a proper amount of cold water, cooperate with the anti-overflow ring 23 to prevent water from overflowing, and then assemble the main box body 11 and the heating box 21 until the lower end of the main box body 11 contacts the support 22, so as to ensure the stability of the installation of the main box body 11. After the main box body 11 is installed, the support plate 31 is nested into the main box body 11 until the extension ring 34 contacts the convex ring 14 to achieve the positioning of the support plate 31. After the assembly is completed, the food to be heated is placed on the support plate 31, and the food is prevented from blocking the tapered hole 32. Finally, the box cover 4 and the main box body 11 are nested and sealed to complete the assembly of the entire device. During heating, the heating bag in the heating box 21 reacts with cold water to release heat, thereby generating high-temperature water vapor. At this time, the water vapor enters the main box body 11 through the air outlet 12 and the tapered hole 32, and is evenly dispersed in the main box body 11, thereby achieving uniform heating of the food on the support plate 31. In addition, the sealing effect of the box cover 4 can prevent the high-temperature steam from escaping quickly, thereby effectively ensuring the heating effect of the food. This is the working principle of the self-heating convenience box with air holes in the inner tank.
