Abstract
The utility model relates to a rapid heating type heat preservation container which comprises a casing and a sealing cover sealing the opening of the casing; a metal inner tank is fixed in the casing; nichrome heating wires are coiled on the outer side surface and/or the outer bottom surface of the metal inner tank in a clinging manner; and an electric bayonet socket is arranged on the side wall of the bottom end of the casing and is electrically connected with the nichrome heating wires. According to the heat preservation container adopting the structure, the nichrome heating wires are coiled on the outer side surface and/or the outer bottom surface of the metal inner tank in a clinging manner, so that the metal inner tank is heated uniformly during heating operation, and the nichrome heating wires have a rapid heating effect, low power and long service life, specifically, the nichrome heating wires can heat up to 50 DEG C in 30 minutes, the power of the nichrome heating wires is 20 W or 30 W generally, and the nichrome heating wires can be used for over 5000 hours.
Description
Technical field
The utility model relates to a kind of cool-bag, relates in particular to a kind of Fast Heating formula cool-bag.
Background technology
At present, existing incubation canteen adopts PTC heat tracing structure mostly, though can play the heat tracing effect, its power is big; Be generally 40W, and heating-up temperature is low, heat time heating time is long; The PTC device damages easily, uses the incubation canteen lost of life, serious restriction insulation result of use.
Summary of the invention
The purpose of the utility model is to solve the deficiency of above-mentioned prior art, and provides a kind of simple and reasonable for structure, heat time heating time weak point, long service life, Fast Heating formula cool-bag that power is low.
The utility model solves the technical scheme that its technical problem adopted: a kind of Fast Heating formula cool-bag; The seal cover that comprises housing and seal casinghousing opening; Be fixed with metal inner tube in the housing, it is characterized in that, being close to the formula coiling on the lateral surface of said metal inner tube and/or the outer bottom has the nickel chromium triangle heater strip; Housing bottom sidewall is provided with the electric mortiser joint chair, and nickel chromium triangle heater strip and electric mortiser joint chair electrically connect; The cool-bag of this structure adopts the nickel chromium triangle heater strip to be and is close to lateral surface and/or the outer bottom that formula is coiled in metal inner tube, and metal inner tube is heated when heating work evenly; And the nickel chromium triangle heater strip has Fast Heating; Be generally and can be heated to 50 degree in 30 minutes, power is low, and power is generally 20W or 30W; Long service life, the nickel chromium triangle heater strip can use more than 5000 hours.
The utility model can also adopt following technical measures to solve: as improvement further, said metal inner tube outer bottom or outer bottom edge are provided with a plurality of fixed supports by circumferencial direction, and the reference column of fixed support and housing bottom is affixed; Make the metal inner tube fixation, connect simply easy accessibility.
Said housing bottom is equipped with power source body, and power source body and nickel chromium triangle heater strip are connected, and power source body is dry cell or rechargeable battery; Power source body can adopt multiple different form structure, improves product and uses flexibility, adapts to different environments for use.
The beneficial effect of the utility model is: a kind of Fast Heating formula cool-bag of the utility model; Adopt the nickel chromium triangle heater strip to be and be close to lateral surface and/or the outer bottom that formula is coiled in metal inner tube; Metal inner tube is heated when heating work evenly; And the nickel chromium triangle heater strip has Fast Heating, and power is low, the advantage of long service life.
