Problems solved by technology
It is composed of an inner tank, an outer shell and additional parts. The existing vacuum flask has the following disadvantages: because its inner tank is composed of two glass bottles inside and outside, during use, if it is accidentally knocked down, the inner tank will be cut. cracks, causing hot water to spray out, which is easy to cause injury accidents; the existing thermos bottle only uses the inner tank for heat preservation, and its heat preservation effect is limited. After a period of use, the heat preservation effect is obviously reduced

The invention discloses a self-heating vacuum flask, which belongs to the technical field of thermal insulation appliance preparation, and comprises a first thermal insulation layer (1), a body (2), electric heating wire layers (3), a second thermal insulation layer (4), a vacuum layer (5), a heat absorption layer (6), a shell (7), an anti-skid pad (8), a flask opening (9), a switch valve (10) anda water outlet (11). A main body (2) is arranged on the inner layer of the first thermal insulation layer (1), and electric heating wire layers (3) are longitudinally installed on the left and rightsides of the main body (2). The self-heating vacuum flask is simple in structure, convenient to use, stable in quality, not prone to breakage and capable of effectively avoiding injury accidents, meanwhile, due to the arrangement of the first heat preservation layer, the electric heating wire layer, the second heat preservation layer, the vacuum layer and the heat absorption layer, when the watertemperature in the vacuum flask is reduced to a set value, heating of the electric heating wire is automatically controlled, and the heat preservation effect is good.
Description
technical field [0001] The invention relates to the technical field of heat preservation appliance preparation, in particular to a self-heating thermos bottle. Background technique [0002] Vacuum bottle is also called electric kettle. It is a kind of modal daily necessities. It is composed of an inner tank, an outer shell and additional parts. The existing vacuum flask has the following disadvantages: because its inner tank is composed of two glass bottles inside and outside, during use, if it is accidentally knocked down, the inner tank will be cut. cracks, hot water is sprayed out, which is easy to cause injury accidents; existing thermos bottles only use the inner tank for heat preservation, and their heat preservation effect is limited. After using for a period of time, the heat preservation effect obviously declines. Contents of the invention [0003] The present invention overcomes the above-mentioned shortcoming, and provides a kind of self-heating thermos bottle....
