Embodiment Construction

[0018] Attached below figure 1 , 2 , 3, 4 describe the present invention in detail:

[0019] A self-heating tank with a double-layer cover, which includes a double-layer cover 1, the double-layer cover 1 has an outer layer card slot 11 and an inner layer card slot 12; the outer layer card slot 11 and the outer layer The layer tank 2 is snap-connected, and the inner layer card slot 12 is snap-connected with the tank 3 to be heated;

[0020] The middle part of the double-layer cover 1 is an easy-pull loop structure 4, and a drawstring 5 is fixed on the back of the easy-pull loop structure 4, and the other end of the drawstring 5 is connected to the water bag 6 in the outer tank 2 For fixing, the water bag 6 is fixedly connected to the fixing plate 7; the self-heating bag 8 is placed on the bottom of the outer tank 2.

[0021] A plurality of vent holes 9 are opened on the double-layer cover body 1.

[0022] The outer edge of the easy-pull ring structure 4 is connected to the inner wall ...

Abstract

The invention relates to a self-heating tank body with a double-layer cover, belonging to the field of self-heating equipment. It includes a double-layer cover body, the double-layer cover body has an outer layer card slot and an inner layer card slot; the outer layer card slot is engaged and connected with the outer layer tank body, and the inner layer card slot is locked with the tank body to be heated The middle part of the double-layer cover is an easy-to-pull ring structure, and a pull rope is fixed on the back of the easy-to-pull ring structure. The other end of the pull rope is connected and fixed with the water bag in the outer tank. The bag is fixedly connected to the fixed plate; the self-heating bag is placed on the bottom of the outer tank. The structure of the invention is ingenious, and the design of the double-layer cover makes it possible to open a relatively closed space between the outer tank body and the tank body to be heated even if the easy-to-pull ring structure is opened, and the safety and heating effectiveness are better. It is guaranteed that the heat generated by the reaction is only discharged through the vent hole to balance the pressure difference inside and outside. After heating, the double-layer cover can be opened to take out the ingredients in the tank to be heated, which is convenient and quick.

Description

Technical field [0001] The invention relates to a self-heating tank with a double-layer cover, belonging to the field of self-heating equipment. Background technique [0002] There are many self-heaters now, all of which require consumers to bring their own water, and then turn on the heater and pour the water into the self-heating bag, chemically react with the substance in the self-heating bag to generate heat, and then put the object to be heated Place it on the upper layer of the self-heating bag for heating. The whole procedure is cumbersome for customers who use it for the first time, and many people are unwilling to read the operation steps of the manual carefully, which is not convenient to use. [0003] There are also patents for hand-held self-heaters, but there is no hand-held self-heater that uses the cover to fix the position of the limit tank, so as to more effectively pull the water bag and the self-heating bag by chemical reaction. Heat. This kind of design that d...
