Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of convenience foods, in particular to a self-heating lunch box cooling device. BACKGROUND

[0002] Self-heating rations are a kind of portable pre-prepared food that uses chemical reaction to generate heat to heat food, usually containing a sealed outer package and an internal heating bag. The heating bag contains quicklime and other auxiliary materials. When used, the appropriate amount of water is poured into the heating bag, and the generated heat will be transferred to the food by conduction, thereby realizing the self-heating function. The whole process does not need to rely on external heat source or power supply, and will not produce smoke or open fire, so it has a wide application in the technical field of outdoor activities, emergency rescue, military operations, etc.

[0003] When water is injected into the heating bag, the quicklime in it will quickly generate a large amount of heat, causing the injected water to quickly boil and vaporize to effectively heat the food. The heated food cannot reach the palatable temperature of instant food due to the high temperature, so it still needs to be naturally cooled for a period of time. This not only affects the user's experience, but also has the potential risk of causing burns. UTILITY MODEL CONTENT

[0004] Therefore, the utility model aims to provide a self-heating lunch box cooling device, which can be used as a heating container for self-heating rations to quickly cool the heated food, and has the advantages of convenient use and high safety.

[0005] To achieve the above purpose, the technical scheme of the utility model is as follows:

[0006] A self-heating lunch box cooling device, comprising a shell with an open mouth;

[0007] A support frame is slidably arranged at the open mouth of the shell;

[0008] A cooling box is rotatably arranged on the support frame;

[0009] A crank is detachably arranged on the shell and can be inserted into the cooling box to drive it to rotate around its own axis.

[0010] Further, a pull ring is fixedly arranged on the support frame.

[0011] Further, a plurality of flow guide holes are arranged on the support frame and the cooling box;

[0012] The flow guide holes are a plurality of equidistantly arranged circular through holes.

[0013] Further, the crank comprises a rod body;

[0014] A limiting screw cap is threadedly connected to one end of the rod body;

[0015] The end of the rod body away from the screw cap is a hexagonal prism, and a limiting groove with a shape consistent with the hexagonal prism is formed in the rotating shaft of the cooling box.

[0016] Further, the outer shell is provided with a heat insulation layer outside, and the heat insulation layer is made of flexible material.

[0017] Further, the cooling box is provided with a baffle which is slidingly arranged on the cooling box.

[0018] Further, a pull tab is vertically and fixedly connected to the baffle.

[0019] Further, the support frame is provided with a protrusion at two ends, and the inner wall of the outer shell is symmetrically provided with a sliding rail, and the protrusion is clamped in the sliding rail.

[0020] Further, a drain pipe is penetratingly arranged at the bottom of the outer shell.

[0021] Compared with the prior art, the self-heating lunch box cooling device has the following advantages:

[0022] The outer shell in the self-heating lunch box cooling device can provide support and limiting for other part structures, and can serve as a container for heating self-heating rations, and compared with using a self-heating ration packaging bag as a heating container, the rigid container has better convenience and safety. The support frame slidingly arranged in the outer shell provides limiting for the installation of the cooling box, so that the cooling box installed on the support frame can enter the outer shell in a sliding manner to facilitate heating food, or can slide out of the outer shell to facilitate cooling the heated food. The cooling box rotatingly arranged on the support frame serves as a placing container for self-heating rations, and can rotate under the driving of the rocker, so as to accelerate the evaporation speed of the surface water to realize rapid cooling of the heated food, thereby improving the user experience.

[0023] Secondly, by pulling the pull ring on one side of the support frame, the user can conveniently pull out the support frame and the cooling box from the outer shell in a pulling manner, thereby reducing the risk of scalding caused by overheating of the support frame. By forming the flow guide holes on the support frame and the cooling box, liquid can flow into or out of the cooling box, thereby reducing the resistance when the support frame is pushed and pulled, and further optimizing the use experience.

[0024] Furthermore, by incorporating an external heat insulation layer, the risk of burns during use can be effectively reduced. The use of a flexible material for the heat insulation layer facilitates easy replacement and cleaning. An internal sliding rail limits the sliding of the support frame, improving its smoothness. A drain pipe at the bottom of the casing facilitates wastewater drainage, enhancing usability. A sliding baffle on the cooling box supports and limits the bagged self-heating rations placed inside, preventing slippage during rotational cooling or as the support frame slides relative to the casing. A lever on the baffle allows for easy movement. Attached Figure Description

The utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] The following will refer to the appendix. Figure 1 To be continued Figure 5 The present invention will be described in detail with reference to the embodiments.

[0038] This embodiment relates to a self-heating lunch box cooling device, which can be used as a heating container for self-heating rations and can quickly cool down the heated food. It has the advantages of being easy to use and highly safe.

[0039] In terms of overall structure, refer to Figure 1 This embodiment of a self-heating lunchbox cooling device includes a shell 1, a support frame 2, a cooling box 3, and a crank handle 4. The shell 1 can be an open, rectangular hollow box. The support frame 2 is slidably disposed at the open position of the shell 1, and can slide into or out of the shell 1 through the open opening. The cooling box 3 is rotatably disposed on the support frame 2, and the crank handle 4 is detachably mounted on the shell 1. The crank handle 4 is configured such that one end can be inserted into the cooling box 3.

[0040] As configured above, the outer shell 1 provides support and restraint for other structural components and serves as a heating container for self-heating rations. Compared to using a self-heating ration packaging bag as a heating container, a rigid container offers better convenience and safety. The support frame 2, slidably mounted within the outer shell 1, restrains the installation of the cooling box 3, allowing it to slide into the outer shell 1 for convenient heating of food, or slide out of the outer shell 1 for convenient cooling of heated food. The cooling box 3, rotating on the support frame 2, serves as a container for self-heating rations. Driven by a rocker arm, it rotates, accelerating the evaporation of surface water to rapidly cool the heated food, improving the user experience.

[0041] Reference Figure 1 and Figure 3 To facilitate pulling the support frame 2 out of the outer casing 1, a pull ring 201 is fixedly installed on the support frame 2. The pull ring 201 is configured as a thin ring with a circular cross-section. Two pull rings 201 can be configured to be arranged vertically and parallel to each other.

[0042] By using the pull ring 201 on one side of the support frame 2, users can easily pull the support frame 2 and the cooling box 3 out of the outer shell 1 by pulling, reducing the risk of burns caused by overheating of the support frame 2.

[0043] Reference Figure 3 and Figure 4 Both the support frame 2 and the cooling box 3 have through-holes. These through-holes can be circular. Multiple through-holes are provided. These through-holes are arranged at certain intervals on the support frame 2 and the cooling box 3, enabling direct communication between the bottom of the cooling box 3 and the interior of the outer shell 1.

[0044] By opening guide holes on the support frame 2 and the cooling box 3, liquid can easily flow into or out of the cooling box 3, reducing the resistance encountered when pushing and pulling the support frame 2, and further optimizing the user experience.

[0045] Reference Figure 4 and Figure 5 The crank handle 4 includes a rod 401 and a limiting nut 402. The limiting nut 402 is threaded onto one end of the rod 401. The diameter of the limiting nut 402 is larger than the diameter of the rod 401. The end of the rod 401 furthest from the limiting nut 402 is hexagonal prism-shaped. A hexagonal prism-shaped limiting groove 301 is provided at one end of the rotating shaft used to constrain the rotational connection between the cooling box 3 and the support frame 2. By inserting the hexagonal prism end of the rod 401 into the limiting groove 301, rotating the crank handle 4 drives the cooling box 3 and the support frame 2 to rotate relative to each other.

[0046] Reference Figure 1 and Figure 2 The outer casing 1 is fitted with a heat insulation layer 101. The heat insulation layer 101 is made of a flexible material. The heat insulation layer 101 can be a soft sleeve made of silicone. A slide rail 102 is provided on the inner wall of the outer casing 1. Protrusions are provided at both ends of the support frame 2. The protrusions are engaged in the slide rail 102 to achieve a sliding connection between the support frame 2 and the outer casing 1. A drain pipe 103 is provided at the bottom of the outer casing 1. The drain pipe 103 communicates with the interior of the outer casing 1.

[0047] By providing a heat insulation layer 101 on the exterior of the outer casing 1, the risk of burns during use can be effectively reduced. Making the heat insulation layer 101 a flexible material facilitates its replacement and cleaning. Providing a slide rail 102 inside the outer casing 1 limits the sliding of the support frame 2, improving the smoothness of its movement. Providing a drain pipe 103 at the bottom of the outer casing 1 facilitates wastewater discharge, enhancing ease of use.

[0048] Reference Figure 1 and Figure 4 A baffle 302 is provided on the cooling box 3, and the baffle 302 is slidably connected to the cooling box 3. A lever is vertically provided on the baffle 302.

[0049] By providing a sliding baffle 302 on the cooling box 3, the bagged self-heating rations placed in the cooling box 3 can be supported and limited, which helps to prevent them from slipping off during the rotational cooling process or when the support frame 2 slides relative to the outer shell 1. By providing a lever on the baffle 302, the movement of the baffle 302 can be facilitated.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
