Description
Technical Field
[0001] This utility model relates to the field of food container technology, specifically to a self-heating pot structure. Background Technology
[0002] Self-heating pots work by heating food through the contact between water and a heating pack inside the container. Traditional self-heating pots consist of a pot body, an inner pot, and a lid. During use, water and the heating pack react at the bottom of the pot body, heating the food inside the inner pot. However, the inner pot of traditional self-heating pots is only supported by flanges around its opening, as shown in patent application number CN202322887181.1. However, if the food inside the inner pot is heavy, the flanges cannot support its weight, and the inner pot may fall to the bottom of the pot body, affecting normal heating. Furthermore, traditional self-heating pots have vents on the lid to release high-temperature steam generated during heating, preventing the pot from "exploding" due to excessive pressure. However, the high-temperature, high-speed steam ejected from the vents can easily burn the user, posing a significant safety hazard. To solve these problems, this application provides a self-heating pot structure. Utility Model Content
[0003] The purpose of this invention is to solve the above-mentioned problems by providing a self-heating pot structure that can better support the inner pot and prevent it from falling to the bottom of the pot; at the same time, it can effectively reduce the risk of burns to personnel.
[0004] The objective of this utility model is achieved through the following technical solution: a self-heating pot structure, comprising:
[0005] The pot body has a supporting protrusion at its bottom, and a heating cavity is formed between the supporting protrusion and the inner wall of the pot body; the inner wall of the pot body is provided with supporting bosses in the circumferential direction.
[0006] The inner liner is placed inside the pot; the upper end of the inner liner is circumferentially provided with a flange. When the inner liner is placed inside the pot, the flange on it is supported on the support protrusion, and its bottom is supported on the support protrusion.
[0007] A lid is placed on the pot body; a pressing protrusion is provided on the lower surface of the lid, and when the lid is placed on the pot body, the circumferential edge of the pressing protrusion presses against the flange of the inner pot.
[0008] This invention solves the problem that traditional methods, which rely solely on the flanges on the inner liner for support, can easily cause the inner liner to fall to the bottom of the pot.
[0009] Furthermore, the upper surface of the support protrusion is provided with several slots circumferentially communicating with the heating cavity. By creating slots on the support protrusion, high-temperature steam in the heating cavity can enter the slots, thereby heating the inner liner at the corresponding part of the support protrusion, making the inner liner more evenly heated.
[0010] The support protrusion is located at the center of the bottom of the pot body.
[0011] The pressing boss has a buffer cavity inside, and the lower surface of the pressing boss has a steam inlet hole communicating with the buffer cavity. The upper surface of the pot lid has a steam outlet hole communicating with the buffer cavity.
[0012] During the heating process, when the pressure inside the self-heating pot is too high, high-temperature steam enters the buffer chamber through the steam inlet. The high-temperature, high-speed steam is buffered in the buffer chamber to slow down the speed at which the steam is ejected from the steam outlet. At the same time, the high-temperature steam is cooled to a certain extent after being buffered, which reduces the temperature of the steam discharged from the steam outlet and reduces the risk of burns to personnel.
[0013] The steam inlet and outlet are staggered, which allows the steam entering the buffer chamber to stay in the buffer chamber, resulting in better buffering and cooling effects.
[0014] The side wall of the pressing boss is provided with a drain outlet communicating with the buffer cavity, and the side wall of the pot body is provided with a water return channel. The water return inlet of the water return channel is located on the supporting boss and corresponds to the position of the drain outlet. The water return outlet of the water return channel is communicating with the heating cavity.
[0015] When high-temperature steam comes into contact with the wall of the buffer chamber, condensate will be generated. The condensate is discharged into the return water channel through the drain outlet, and then flows back into the heating chamber for reuse.
[0016] The bottom of the buffer chamber gradually rises from the side closest to the drain outlet to the other side, which facilitates the collection of condensate into the drain outlet.
[0017] The steam outlet is equipped with an adsorption element, which can adsorb moisture in the steam. By reducing the moisture content of the steam, the steam becomes relatively dry steam. In this way, even if a person accidentally comes into contact with the steam discharged from the steam outlet, the degree of burn can be reduced.
[0018] The pot body and the pot lid are respectively provided with corresponding support ears; the support ears on the pot body are provided with positioning grooves, and the support ears on the pot lid are provided with positioning protrusions that cooperate with the positioning grooves.
[0019] The inner liner is equipped with a partition plate that divides its internal space into several storage spaces.
[0020] Compared with the prior art, this application has the following beneficial effects:
[0021] (1) This utility model solves the problem that the inner liner is prone to falling into the bottom of the pot by supporting the inner liner with the support protrusion.
[0022] (2) The present invention can slow down the speed of steam ejection from the steam outlet through the buffer chamber; at the same time, the high temperature steam is cooled to a certain extent after being buffered, so that the temperature of the discharged steam is reduced and the risk of people being burned is reduced.

[0040] Example
[0041] like Figure 1 As shown, this embodiment discloses a self-heating pot structure, which includes: a pot body 1, an inner liner 2, and a pot lid 3. The pot body 1 has a supporting protrusion 6 inside, located at the center of the bottom of the pot body 1, forming an annular heating cavity between the protrusion and the inner wall of the pot body 1. In use, heating packs can be placed inside the heating cavity; multiple heating packs can be placed evenly within the heating cavity, and then water is poured into the heating cavity. The water generates a large amount of heat upon contact with the heating packs. Alternatively, the heating packs can be arranged in an annular shape to match the annular heating cavity.
[0042] The inner pot 2 is placed inside the pot body 1. The upper end of the inner pot 2 has a flanged edge, and correspondingly, the inner wall of the pot body 1 has a supporting protrusion 14. When the inner pot 2 is placed inside the pot body 1, its flanged edge is supported by the supporting protrusion 14, and its bottom is supported by the supporting protrusion 6. This embodiment solves the problem that the inner pot 2 easily falls to the bottom of the pot body 1 when supported only by the flanged edge in traditional methods.
[0043] The lid 3 is placed over the pot body 1 to seal the pot body 1. For example... Figure 3 As shown, the lower surface of the lid 3 is provided with a pressing protrusion 15. When the lid 3 is closed on the pot body 1, the circumferential edge of the pressing protrusion 15 can press against the flange of the inner pot 2, which can also help to fix the inner pot 2.
[0044] When using, add food into the inner pot 2, and add a heating pack and water into the heating chamber of the pot body 1. Quickly place the inner pot 2 into the pot body 1 and close the lid 3 on the pot body 1. The steam generated by the reaction of the heating pack and water will heat or cook the food in the inner pot 2.
[0045] As a preferred option, such as Figure 2As shown, the inner liner 2 is equipped with a partition 7 that divides its internal space into several storage compartments. In use, each storage compartment can hold different foods.
[0046] Because the bottom of the inner liner 2 is supported on the support protrusion 6, the part of the inner liner 2 supported on the support protrusion 6 is not easily in contact with steam, resulting in uneven heating. Therefore, as Figure 1 As shown, the upper surface of the support protrusion 6 has several slots 18 circumferentially arranged to communicate with the heating cavity. In this embodiment, by opening slots 18 on the support protrusion 6, high-temperature steam in the heating cavity can enter the slots 18. The high-temperature steam entering the slots 18 can contact the area on the inner liner 2 corresponding to the support protrusion 6, thereby heating that area and making the inner liner 2 more evenly heated.
[0047] like Figure 3 , 4 As shown, the pressing boss 15 has a buffer cavity 8 inside, the lower surface of the pressing boss 15 has a steam inlet 9 communicating with the buffer cavity 8, and the upper surface of the pot lid 3 has a steam outlet 5 communicating with the buffer cavity 8.
[0048] During the heating process, the steam generated by the reaction between the heating element and water can be discharged from the steam outlet 5, preventing excessive pressure within the self-heating pot structure from causing an "explosion". Due to the buffer chamber 8, high-temperature steam enters from the steam inlet 9. The high-temperature, high-speed steam is buffered within the buffer chamber 8, preventing the "pulse-like" violent eruption of steam during the initial intense reaction, resulting in smoother and more continuous steam discharge and reducing the risk of burns. Simultaneously, the high-temperature steam is cooled to a certain extent after buffering, lowering the temperature of the steam discharged from the steam outlet 5 and reducing the risk of burns. Furthermore, the high-temperature steam condenses into water upon contact with the walls of the buffer chamber 8, reducing the moisture content of the steam.
[0049] In addition, such as Figure 4 As shown, the steam inlet 9 and the steam outlet 5 are staggered. This staggered arrangement ensures that the steam entering the buffer chamber 8 from the steam inlet 9 will not immediately exit from the steam outlet 5, but will flow within the buffer chamber 8, thus achieving a better buffering and cooling effect.
[0050] like Figure 5-8 As shown, the side wall of the pressing boss 15 is provided with a drain outlet 11 communicating with the buffer cavity 8. The side wall of the pot body 1 is provided with a water return channel 13. The water return inlet 16 of the water return channel 13 is located on the supporting boss 14 and corresponds to the position of the drain outlet 11. The water return outlet 17 of the water return channel 13 communicates with the heating cavity. Specifically, the width of the supporting boss 14 is greater than the width of the flange on the inner liner 2 to avoid the flange from blocking the water return inlet 16.
[0051] When high-temperature steam comes into contact with the wall of the buffer chamber 8, condensate will be generated. The condensate is discharged into the return water channel 13 through the drain outlet 11, and then flows back into the heating chamber for reuse. This also prevents a large amount of condensate stored in the buffer chamber 8 from leaking out when the lid 3 is opened later, causing inconvenience. In specific settings, a water level warning line will be set on the inner wall of the pot body 1 to indicate the maximum water level that can be added during use. The return water outlet 17 can be set above the water level warning line. In addition, a water-blocking sleeve can also be set at the position of the steam inlet 9. The water-blocking sleeve surrounds the steam inlet 9. Under the obstruction of the water-blocking sleeve, the condensate generated in the buffer chamber 8 will not fall into the inner liner from the steam inlet 9. Of course, the length of the water-blocking sleeve must be less than the height of the buffer chamber 8 to avoid affecting the steam entering the buffer chamber 8.
[0052] In specific settings, the drain outlet 11 can be set to tilt slightly downwards. When the lid 3 is placed on the pot body 1, the drain outlet 11 can be inserted into the return water inlet 16.
[0053] like Figure 1 As shown, the pot body 1 and the pot lid 3 are respectively provided with corresponding support ears 4; the support ears 4 on the pot body 1 are provided with positioning grooves, and the support ears 4 on the pot lid 3 are provided with positioning protrusions that cooperate with the positioning grooves. When the support ears 4 on the pot body 1 and the support ears 4 on the pot lid 3 are aligned, and the pot lid 3 is placed on the pot body 1, the positioning protrusions are engaged in the positioning grooves, and at this time the drain outlet 11 is aligned with the return water inlet 16. Two support ears 4 can be symmetrically provided on both the pot body 1 and the pot lid 3, and marked "left" and "right" for easy distinction. When the lid is closed, the "left" support ear 4 on the pot lid 3 is aligned with the "left" support ear 4 on the pot body 1, and the "right" support ear 4 on the pot lid 3 is aligned with the "right" support ear 4 on the pot body 1.
[0054] In addition, the bottom of the buffer chamber 8 gradually rises from the side closest to the drain outlet 11 to the other side, which facilitates the collection of condensate into the drain outlet 11.
[0055] As an alternative, an adsorption element 12 is provided on the steam outlet 5. The adsorption element 12 can be a food-grade sponge. During installation, the wall of the steam outlet 5 can be provided with a circumferentially oriented snap-fit, and the circumferential edge of the adsorption element 12 can be inserted into the snap-fit to fix the adsorption element 12 in place.
[0056] The adsorption element 12 can adsorb moisture in the steam, thereby reducing the moisture content of the steam and making it relatively dry. In this way, even if a person accidentally comes into contact with the steam discharged from the steam outlet 5, the degree of burn can be reduced.
[0057] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.
[0058] Furthermore, the specific embodiments described above are exemplary.

Those skilled in the art should understand that this utility model specification and its drawings are illustrative and not intended to limit the scope of the claims.
