Self-heating tank with double-layer cover

Abstract

The invention relates to a self-heating tank with a double-layer cover and belongs to the field of self-heating equipment. The self-heating tank with the double-layer cover comprises the double-layer cover. An outer-layer clamping groove and an inner-layer clamping groove are formed in the double-layer cover. The outer-layer clamping groove is in clamping connection with an outer-layer tank body. The inner-layer clamping groove is in clamping connection with a tank body to be heated. The middle of the double-layer cover is of an easy-to-pull ring structure. A pull rope is fixed to the back face of the easy-to-pull ring structure and the other end of the pull rope is fixedly connected with a water bag in the outer-layer tank body. The water bag is fixedly connected to a fixing board. A self-heating bag is placed at the bottom of the outer-layer tank body. The self-heating tank is ingenious in structure; due to the design of the double-layer cover, even though the easy-to-pull ring structure is pulled, a relatively-tight space is formed between the outer-layer tank body and the tank body to be heated, the safety and the heating efficiency are better guaranteed, heat generated by a reaction is only discharged from an air outlet, and the pressure difference between inside and outside is balanced. After heating is completed, the double-layer cover is opened, the tank body to be heated is taken out, and food in the tank body to be heated is eaten, and the self-heating tank is convenient and rapid to use.

Description

technical field [0001] The invention relates to a self-heating tank body with a double-layer cover, belonging to the field of self-heating equipment. Background technique [0002] There are many self-heating heaters now, all of which require consumers to bring their own water, then turn on the heater and pour the water into the self-heating package, which will chemically react with the substances in the self-heating package to generate heat, and then put the object to be heated It is placed on the upper layer of the self-heating bag for heating. The whole procedure is cumbersome for first-time customers, and many people are unwilling to read the operation steps in the manual carefully, so it is not convenient to use. [0003] At present, there are also patents for hand-held self-heaters, but there is no hand-drawn self-heater that uses the cover to fix the position of the limit tank, so that the chemical reaction between the water bag and the self-heating bag can be more eff...
