Description

Technical field:

[0001] The utility model relates to the field of self-heating food of daily necessities. Background technology:

[0002] As people's living standards continue to improve, their pace of life is accelerating and traveling has become normalized, self-heating food has naturally become people's first choice.

[0003] The self-heating boxes on the market require people to tear open the water bag and mix it with the heating pack. Some people put the heating pack in the box first, then add water, and then place the inner liner containing food on limestone to heat the food. The disadvantage is that the outer shell of the box is large, which increases the cost of the product. Therefore, it is urgent to design a self-heating box that heats quickly and at a low cost to solve the above problems, so this self-heating box that is easy to use, simple to operate and low in cost was produced.

[0004] Compared with a multifunctional self-heating box disclosed by our company in 2021 (patent number: ZL202120677397.3), the volume of this self-heating box will be smaller, thereby reducing the cost. Summary of the invention:

[0005] The utility model aims to provide a self-heating box which has lower cost, simple structure and convenient and quick use. The self-heating box is in a square or cylindrical shape.

[0006] The content of the invention is:

[0007] The task of the utility model is to provide a self-heating box with a simple structure and convenient use. The self-heating box has a square shape and is composed of three parts, namely, a heating box body 4, an inner box 6 and a water cup 5. A heating pack 14 is installed in the heating box body 4. The main component of the heating pack is calcium oxide. A heating box air outlet 3 is provided on the heating box body 4. The heating box air outlet 3 is sealed with a plastic sealing film 10, so that the interior of the heating box body 4 forms a closed space, which can effectively prevent the heating pack 14 from absorbing moisture from the outside air. The upper surface of the inner box 6 is sealed with a plastic sealing film 10. The lid 1 is sealed, and an air outlet pipe 2 is provided inside the inner box 6 and fixed together with the box bottom 9 to form a whole. An air outlet pipe cap 7 is provided on the top of the air outlet pipe 2. The function of the air outlet pipe cap 7 is that when the lid 1 is covered on the top of the inner box 6, the inside of the inner box 6 can form a closed space, which protects the food in the inner box 6 from spoiling. The water cup 5 is filled with water 12, and the top of the water cup 5 is sealed with a sealing film 13. The bottom of the water cup 5 is provided with a cup bottom air inlet pipe 11, and the bottom of the cup bottom air inlet pipe 11 is sealed with an air inlet pipe cap 8 to prevent the water 12 in the water cup 5 from flowing out.

[0010] Figure 3 This is the appearance of the components of the utility model self-heating box

[0011] The utility model is a self-heating box. The self-heating box of the device in the figure has a square appearance and comprises: a cover 1; an air outlet pipe 2; a heating box air outlet 3; a heating box body 4; a water cup 5; an inner box 6; an air outlet pipe cap 7; an air inlet pipe cap 8; a box bottom 9; a plastic sealing film 10; an air inlet pipe 11 at the bottom of the cup; water 12; a sealing film 13; a heating pack 14; Specific implementation method:

[0012] The utility model provides a self-heating box. The technical scheme in the embodiment of the utility model is described clearly and completely below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention. Please refer to Figure 1 -- Figure 3 .

[0013] First, tear off the plastic sealing film 10 from the air outlet 3 of the heating box, then tear off the sealing film 13 on the water cup 5, and then pour water 12 into the heating box body 4 from the air outlet 3 of the heating box. At this time, the heating pack 14 will absorb the water 12. When the calcium oxide in the heating pack 14 reacts with the water, a large amount of heat and water vapor will be released. At this time, unscrew the air inlet pipe cap 8 on the air inlet pipe 11 at the bottom of the cup and put it into the air outlet 3 of the heating box. When the water cup 5 is placed steadily, you can see the water vapor in the heating box body 4 coming out from the bottom of the cup. The air enters the water cup 5 through the air inlet pipe 11 and is released to the outside. At this time, the cover 1 on the inner box 6 is unscrewed. After opening the cover 1, the air outlet pipe cap 7 is unscrewed from the air outlet pipe 2. At this time, the inner box 6 is put into the water cup 5. At this time, the water vapor in the water cup 5 will be discharged through the air outlet pipe 2 arranged in the inner box 6. At this time, the cover 1 is gently covered on the inner cup 6. When the water vapor is discharged, the food in the inner box 6 will absorb the heat from the water vapor, so that the food in the inner box 6 is heated.

[0014] The above is only one embodiment of the present invention. A person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, which all fall within the protection scope of the present invention.
