Technical Field
[0001] The utility model belongs to the technical field of food lunch boxes, and particularly relates to a multifunctional lunch box. Background Art
[0002] In people's daily life, lunch boxes are often needed to deliver or carry meals to facilitate work, study or taking care of patients. However, the food in the lunch box will quickly get cold and is not suitable for people to eat. To overcome this problem, various styles of heat-insulated lunch boxes have emerged on the market for people to use. Existing heat-insulated lunch boxes usually include a lid, a housing and an inner pot. In order to keep warm for a long time after heating, some heat-insulated lunch boxes are also provided with a heat-insulating structure inside the housing, and the heat transfer efficiency between the inside and outside of the heat-insulating structure is reduced to slow down the heat transfer speed between the inside and outside of the housing, so as to achieve the purpose of long-term heat preservation. However, the heat-insulating structure with good heat preservation effect has too high manufacturing cost and is difficult for people to bear. Moreover, after the food gets cold, adding hot water again cannot quickly heat the food. It is necessary for the hot water to dissipate heat to heat the heat preservation cavity and then heat the food, which also causes heat loss. Content of the Utility Model
[0003] In view of this, the purpose of the utility model is to provide a multifunctional lunch box to solve the problem that after the food gets cold, adding hot water again cannot quickly heat the food. It is necessary for the hot water to dissipate heat to heat the heat preservation cavity and then heat the food, which also causes heat loss.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:
[0005] A multifunctional lunch box of the utility model includes a main box and a lid. The lid is buckled on the upper part of the main box. A plurality of food compartments are arranged in the main box. A heat preservation layer is detachably connected to the lower part of the main box. A water storage tank is slidably connected in the heat preservation layer. A waterproof pipe is connected in the water storage tank. A screw rod is rotatably connected to the outside of the heat preservation layer. The screw rod penetrates through the heat preservation layer. The screw rod penetrates through the waterproof pipe and is threadedly connected to the waterproof pipe.
[0006] Further, the areas of the plurality of food compartments are different.
[0007] Further, the screw rod located outside the heat preservation layer is connected with a handle.
[0008] Further, a placement groove is arranged on the upper part of the lid. Tableware can be placed in the placement groove. A sliding lid is slidably connected to the upper part of the placement groove. A baffle is connected to one side of the sliding lid.
[0009] Further, a handle is connected to the upper part of the lid.
[0010] The beneficial effects of the utility model are as follows:
[0011] The utility model relates to a multifunctional lunch box. The water storage tank is driven by a screw rod to move closer to the main box to heat the main box, so as to improve the heating efficiency of the main box. Different kinds of food can be placed in multiple food compartments. Tableware can be placed in a placement groove, and then a sliding cover is used to prevent dust from entering the placement groove.
[0012] Other advantages, objectives and features of the utility model will be described in the following specification, and to some extent, they are obvious to those skilled in the art, or those skilled in the art can be taught from the practice of the utility model. The objectives and other advantages of the utility model can be achieved and obtained through the following specification. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] As Figures 1 to 5As shown in the figure, a multifunctional lunch box of the present utility model includes a main box 1 and a lid 2. The lid 2 is buckled on the upper part of the main box 1, and a handle 7 is connected to the upper part of the lid 2 for easy holding. A plurality of food compartments 10 are provided in the main box 1 for placing food, and the areas of the plurality of food compartments 10 are different to place different types of food. A heat preservation layer 3 is detachably connected to the lower part of the main box 1 to keep the food warm. A water storage tank 11 is slidably connected in the heat preservation layer 3 for placing hot water to keep the food warm. A waterproof pipe 12 is connected in the water storage tank 11 to prevent water leakage. A screw rod 8 is rotatably connected to the outside of the heat preservation layer 3. The screw rod 8 located outside the heat preservation layer 3 is connected with a handle 9. Rotating the handle 9 makes the screw rod 8 rotate, and the screw rod 8 drives the water storage tank 11 to move. The screw rod 8 passes through the heat preservation layer 3, and the screw rod 8 passes through the waterproof pipe 12 and is threadedly connected with the waterproof pipe 12, and the screw rod 8 drives the waterproof pipe 12 to move.
