Description

Technical Field

[0001] This utility model relates to the field of food cans, and in particular to a rotary-triggered self-heating empty food can. Background Technology

[0002] With the fast pace of modern life, people's demand for convenient and immediate food is increasing. Traditional heating methods, such as using stoves and microwave ovens, are limited by space and equipment conditions and cannot meet people's needs for hot food outdoors or while traveling. Although the number of self-heating foods on the market is gradually increasing, they generally suffer from problems such as poor heating effect and inadequate safety. The heating packs of some self-heating foods do not react sufficiently, resulting in insufficient heat and failure to heat the food to the appropriate temperature; some self-heating foods have unreasonable sealing and pressure relief designs, posing safety hazards during the heating process.

[0003] Furthermore, existing self-heating food packaging is complex in structure and inconvenient to operate, affecting user experience. Therefore, developing a self-heating food container that is efficient in heating, safe, reliable, and easy to operate is of significant practical importance. Utility Model Content

[0004] The purpose of this invention is to provide a rotary-triggered self-heating food can, which solves the problems mentioned above.

[0005] This utility model is achieved through the following technical solution:

[0006] A rotary-triggered self-heating food can includes a heating base and an upper sidewall. The heating base and the upper sidewall are movably connected to allow the heating base to rotate. A vent plate is fixedly installed on the heating base near the connection with the upper sidewall. A water bag is installed in the middle of the lower surface of the vent plate. Water bag breaking components are installed on both sides of the water bag through the sidewall of the heating base. A horizontal water distribution plate is installed below the water bag. A heating pack is placed between the water distribution plate and the base. A food compartment is fixedly installed on the upper surface of the vent plate.

[0007] Furthermore,

[0008] The top of the side wall of the heating base has a first groove and a second groove with openings facing outwards. The opening of the second groove is smaller than that of the first groove. The vertical side wall of the first groove has shallow arc-shaped grooves evenly distributed along the groove.

[0009] Furthermore,

[0010] Near the bottom end of the upper sidewall, a protrusion is formed that protrudes inward and matches the first groove. The bottom end of the upper sidewall is bent inward and inserted into the second groove. A sealing plate is fixedly connected to the top of the inner side of the upper sidewall, and a pressure relief hole is opened on the sealing plate. Elastic silicone is provided on the outer side of the upper sidewall to block the pressure relief hole.

[0011] Furthermore,

[0012] The vertical outer wall of the protrusion is uniformly provided with elastic rubber columns along the protrusion, and each elastic rubber column has a ball at its end, which corresponds and matches the shallow groove one by one.

[0013] Furthermore,

[0014] The water bag destruction component includes a button, a spring, a stop block, and a pointed blade. The stop block is vertically disposed on the lower surface of the vent plate and distributed on both sides of the water bag, with holes for the blade to pass through. The button passes through the side of the heating base and a pointed blade is fixedly disposed on the end of the button facing the stop block. The pointed blade is fitted with a spring, and the two ends of the spring are connected to the button and the stop block respectively. When the spring is in its normal state, the end of the pointed blade is exactly in the hole of the stop block.

[0015] Furthermore,

[0016] The water bag is divided into an installation part and a water storage part, and the installation part is fixedly connected to the lower surface of the breathable plate.

[0017] Furthermore,

[0018] A movable groove is provided at the upper part of the outer side of the food compartment, which allows the sealing plate to be inserted.

[0019] The beneficial effects of this utility model are:

[0020] 1. The heating base and the upper sidewall are connected via a "first groove + second groove" and the protrusions and bends of the upper sidewall, ensuring a tight and rotatable connection. The shallow arc-shaped groove on the sidewall of the first groove matches the ball at the end of the elastic rubber column on the upper sidewall, providing rotational damping and positioning functions. This provides clear tactile feedback during operation, preventing over- or under-rotation from affecting use, while also preventing accidental slippage or detachment and ensuring structural stability.

[0021] 2. The water bag puncture component adopts a "button + spring + tip blade" linkage design. Under normal conditions, the spring keeps the blade retracted in the stop hole to prevent accidental puncture of the water bag and leakage. When the button is pressed, the blade extends and punctures the water bag. After releasing the button, the spring automatically returns to its original position. The operation is simple and reliable, achieving both rapid triggering of the heating reaction and improved safety.

[0022] 3. The sealing plate inside the upper side wall cooperates with the movable groove outside the food compartment to form a sealed space, ensuring the airtightness of the food compartment during heating. The pressure relief hole on the sealing plate is blocked by the outer elastic silicone. When the internal steam pressure is too high, the elastic silicone is pushed open to release pressure, preventing the risk of explosion due to excessive pressure and improving the safety of use.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0033] See Figures 1 to 4 :

[0034] A rotary-triggered self-heating food can includes a heating base 1 and an upper sidewall 2. The heating base 1 and the upper sidewall 2 are movably connected to allow the heating base 1 to rotate. A vent plate 4 is fixedly installed on the heating base 1 near the connection with the upper sidewall 2. A water bag 5 is installed in the middle of the lower surface of the vent plate 4. Water bag breaking components 6 are installed on both sides of the water bag 5 through the sidewall of the heating base 1. A horizontal water distribution plate 7 is installed below the water bag 5. A heating pack 8 is placed between the water distribution plate 7 and the base. A food compartment 3 is fixedly installed on the upper surface of the vent plate.

[0035] Furthermore, the top of the side wall of the heating base 1 is formed with a first groove 10 and a second groove 11 opening outwards from the base. The opening of the second groove 11 is smaller than that of the first groove 10. The vertical side wall of the first groove 10 has arc-shaped shallow grooves 12 evenly distributed along the groove.

[0036] The first groove 10, the second groove 11, and the shallow groove 12 provided on the side wall of the heating base 1 form a locking structure for connection with the upper side wall 2. The opening of the first groove 10 faces outward and is larger than that of the second groove 11, which facilitates the insertion of the protrusion 20 and the bent part of the upper side wall 2 to form a stable movable connection. The arc-shaped shallow groove 12 is evenly distributed on the side wall of the first groove 10, providing locking points for the elastic rubber pillars 201 and beads 202 of the upper side wall 2, so that the heating base 1 has a damping feel and positioning function when rotating, and avoids accidental slippage or disengagement.

[0037] Furthermore,

[0038] Near the bottom end of the upper sidewall 2, a protrusion 20 is formed inward and matches the first groove 10. The bottom end of the upper sidewall 2 is bent inward and inserted into the second groove 11. A sealing plate 21 is fixedly connected to the top of the inner side of the upper sidewall 2. A pressure relief hole 22 is opened on the sealing plate 21. An elastic silicone 23 is provided on the outer side of the upper sidewall 2 to block the pressure relief hole 22.

[0039] The protrusion 20 and the bend of the upper sidewall 2 are inserted into the groove of the heating base 1 to achieve a tight connection and rotational guidance; the sealing plate 21 and the pressure relief hole 22 work together with the elastic silicone 23 to ensure the airtightness of the food compartment 3 and to automatically relieve pressure when the internal pressure is too high, thus avoiding the risk of explosion.

[0040] Furthermore,

[0041] Elastic rubber pillars 201 are uniformly and vertically arranged along the outer wall of the protrusion 20. Each elastic rubber pillar 201 has a bead 202 at its end, and the bead 202 corresponds and matches the shallow groove 12 one by one.

[0042] The elastic rubber column 201 and the ball 202 match the shallow groove 12 to provide damped positioning for the rotation of the heating base 1, making the operation feel clear and preventing the use from being affected by excessive or insufficient rotation (such as incomplete sealing).

[0043] Furthermore,

[0044] The water bag destruction component 6 includes a button 60, a spring 61, a stop block 62, and a pointed blade 63. The stop block 62 is vertically disposed on the lower surface of the vent plate 4 and distributed on both sides of the water bag 5, and has holes for the blade to pass through. The button 60 passes through the side of the heating base 1 corresponding to the stop block 62, and the pointed blade 63 is fixedly disposed on the end of the button 60 facing the stop block 62. The pointed blade 63 is fitted with the spring 61, and the two ends of the spring 61 are connected to the button 60 and the stop block 62 respectively. When the spring 61 is in its normal state, the end of the pointed blade 63 is exactly in the hole opened in the stop block 62.

[0045] The water bag puncture component 6, through the linkage of button 60, spring 61, and tip blade 63, enables convenient puncturing of the water bag 5. Spring 61 normally keeps the blade retracted; pressing button 60 extends the blade to puncture the water bag 5 and rotates the heating base 1 to cut the water bag 5. Releasing the button automatically resets the button. The structure is simple, the operation reliable, and it avoids accidental activation or leakage. Furthermore,

[0046] The water bag 5 is divided into an installation part 50 and a water storage part 51. The installation part 50 is fixedly connected to the lower surface of the breathable plate 4.

[0047] The water bag 5 is divided into an installation part 50 and a water storage part 51. The installation part 50 is fixed on the vent plate 4 to ensure the stability of the water bag 5. The water storage part is located above the water distribution plate 7, which facilitates the even distribution of water flow after puncture and avoids uneven reaction caused by concentrated impact on the heating pack 8.

[0048] Furthermore,

[0049] A movable groove 30 is provided on the upper part of the outer side of the food compartment 3, which allows the sealing plate 21 to be inserted.

[0050] The movable groove 30 on the outer side of the food compartment 3 matches the sealing plate 21 on the upper side wall 2, ensuring that the sealing plate 21 forms a seal with the space below after insertion, preventing a large amount of hot air from being lost during heating, and at the same time, it works with the pressure relief hole 22 to achieve pressure control.

[0051] The method of using this utility model is as follows:

[0052] Firstly, assembly is achieved through the movable connection structure between the heating base 1 and the upper side wall 2: the first groove 10 and the second groove 11 at the top of the side wall of the heating base 1 engage with the protrusion 20 at the bottom of the upper side wall 2 (the inner protrusion 20 matches the first groove 10) and the end bent inward and inserted into the second groove 11. At the same time, the end ball 202 of the elastic rubber column 201 on the outer side of the protrusion 20 of the upper side wall 2 is embedded in the arc-shaped shallow groove 12 of the side wall of the first groove 10 of the heating base 1, providing rotational damping and positioning, ensuring stable connection and rotatable adjustment.

[0053] When in use, press the button 60 of the water bag breaking component 6 on the side wall of the heating base 1. The tip blade 63, which is fitted with a spring 61, overcomes the resistance of the spring 61 under the pressure of the press and extends out from the hole of the stop block 62 to puncture the water bag 5 (the water bag 5 is fixed to the mounting part 50 and the water storage part 51 on the lower surface of the vent plate 4). At the same time, the heating base 1 can be rotated to drive the tip blade 63 to cut the water bag and thus adjust the water output. During the rotation, the end ball 202 of the elastic rubber column 201 and the arc-shaped shallow groove 12 on the side wall of the first groove 10 of the heating base 1 form a stop to inform the operator of the current degree of cutting of the water bag 5. The water in the water storage part 51 flows evenly to the heating pack 8 through the water distribution plate 7 below, triggering an exothermic reaction. The heating pack 8 is commonly used in conventional self-heating food packaging.

[0054] Heat is transferred to the upper food compartment 3 through the vent plate 4 to heat the food. At the same time, the sealing plate 21 inside the upper side wall 2 is inserted into the movable groove 30 on the outer side of the food compartment 3 to form a sealed space. When the internal steam pressure is too high, the pressure relief hole 22 on the sealing plate 21 is pushed open by the outer elastic silicone 23 to release the pressure and ensure safety.

[0055] After releasing button 60, spring 61 resets and drives the blade to retract into the hole of stop block 62, completing the puncture of water bag 5 and structural reset.

[0056] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
