[0022] Such as Figure 1 and Figure 2As shown in the figure, a self-heating food box includes a box cover 1, an inner box 3, a box body 2, and an outer box 4. The inner box 3 is disposed inside the box body 2, the box cover 1 is closed on the box body 2, and the outer box 4 is nested outside the box body 2. There is a gap 26 between the outer box 4 and the box body 2. The setting of the outer box supports the box body and also prevents the heating part of the box body from directly contacting the outside world, ensuring safe use.
[0023] As Figure 1 shown in the figure, the box body 2 includes a first accommodation step 21, a second accommodation step 23, and a third accommodation cavity 25. The first accommodation step 21 and the second accommodation step 23 are in an L shape. A first accommodation cavity is formed inside the first accommodation step 21, and a second accommodation cavity is formed inside the second accommodation step. The first accommodation cavity, the second accommodation cavity, and the third accommodation cavity communicate with each other. The box cover 1 is disposed inside the first accommodation cavity. An air outlet 11 is provided on the box cover 1, and the air outlet is set at the middle position of the box cover. Since the water vapor in the third accommodation cavity flows upward from the edge of the side wall of the box body, setting the air outlet in the middle of the box body can prevent the water vapor at the bottom from directly flowing out upward from the air outlet, improving the utilization rate of the water vapor. A second accommodation cavity is formed inside the second accommodation step 23, and the inner box 3 is disposed inside the second accommodation cavity. A protruding edge 12 is provided below the box cover 1. During installation, the protruding edge 12 is snap-fitted on the first accommodation step 21, and a snap-fastening device is also provided at the edge of the protruding edge and the first accommodation step. The snap-fastening device increases the sealing performance between the box cover and the box body.
[0024] A ventilation hole 24 is provided at the edge of the second accommodation step 23. The diameter of the inner box 3 is smaller than the inner diameter of the second accommodation cavity, which is convenient for placing or taking out the inner box. A third accommodation cavity 25 is provided below the second accommodation step. The first accommodation cavity, the second accommodation cavity, and the third accommodation cavity 25 communicate with each other. During use, a heating pack and water are placed in the third accommodation cavity 25 to generate heat and water vapor. The water vapor heats the bottom of the inner box and at the same time flows upward through the ventilation hole 24 to heat the side wall of the inner box. An outer box 4 is also provided below the first accommodation step 21. The outer box 4 is nested outside the box body 2 from below the first accommodation step 21, and there is a gap 26 between the outer box 4 and the box body 2. The outer box 4 is nested below the L-shaped first accommodation step of the box body, which will not increase the width of the entire food box. At the same time, the setting of the outer box prevents the heating part of the box body from directly contacting the outside world, ensuring safe use. At the same time, it plays a supporting role for the box body when the box body is softened and tilted during heating.
[0025] As Figure 1 and Figure 2As shown, the inner box 3 includes an inner layer 31 and an outer layer 32, and the inner layer 31 is enclosed in the outer layer 32. The inner box 3 is circular, and the inner layer 31 and the outer layer 32 are both annular. A first heating area is formed in the inner layer 31, and a second heating area is formed between the outer layer 32 and the inner layer 31. The heating position of the first heating area is mainly concentrated at the bottom of the inner box, that is, the heat conduction in the third accommodating cavity, and the heating position of the second heating area is mainly concentrated at the bottom of the inner box and the side wall of the inner box, that is, the heat conduction in the third accommodating cavity and the second accommodating cavity. The setting of the inner box can hold foods with different heating requirements separately, and foods with a high degree of heating are placed in the second heating area to ensure that foods with different heating requirements can be fully heated and eaten.
[0026] The diameter of the first accommodating cavity is greater than the diameter of the second accommodating cavity, the diameter of the second accommodating cavity is greater than the diameter of the third accommodating cavity 25, and the thickness of the side wall and bottom wall of the third accommodating cavity 25 is greater than the thickness of other parts of the box body 2. The second accommodating step is L-shaped, and the thickness of the side wall formed below the L-shape is greater than the thickness above, and the bottom thickness is equivalent to the side wall thickness, forming a third accommodating cavity. The area with extra side wall thickness forms the second accommodating step, and the inner box is placed on the second accommodating step. At the same time, a plurality of vents are provided on the second accommodating step. When the inner box is placed on the second accommodating step, water vapor flows into the second accommodating cavity from the vents and heats the side wall of the inner box.
[0027] The box body and the outer box are mutually engaged and installed, specifically: a first embedding portion 22 is provided below the first accommodating step 21, a second embedding portion 27 is provided at the bottom of the box body 2, and the box body 2 is engaged and connected with the outer box 4 through the first embedding portion 22 and the second embedding portion 27.
[0028] The utility model provides a safe self-service heating food box. Through the outer box, the heating part of the food box is prevented from directly contacting the outside world and plays a certain degree of supporting role on the box body, avoiding possible safety hazards. In addition, the bottom and side walls of the box body where the heat is the largest are thickened to prevent the box body from softening during heating, causing tilting and collapse, thereby causing the food in the inner box to spill out. The inner box of the utility model is provided with two heating areas with different heating degrees. The different heating surfaces during heating make the heating degrees in the same time different. Foods with different heating requirements are placed in different areas, and the food with different heating requirements can be heated at one time.
[0029] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
