A kind of multifunctional ice bag incubator

Abstract

The invention provides a multifunctional ice bag heat preservation box. An inner bulge part presses a third elastic communication pipe at an outer bulge part, so that gas in a second elastic air bag cannot flow back gas and can be kept in the second elastic air bag, an annular elastic air bag gradually extends into an annular clamping groove and corresponds to a lower groove portion, a first communication end and a second communication end are correspondingly connected together, the gas in a gas containing cavity enters the annular elastic air bag along a second air circulation layer through asealing air guide pipe, the annular elastic air bag is expanded and tightly attached and buckled to the annular clamping groove, and an outer thread section is matched with an inner thread section toconnect a piston knob and a box cover together for fixation. The heat preservation box is carried upside down, the second elastic air bag can be used for carrying out effective elastic supporting andbuffering on the object according to the elastic supporting force accumulated by the gravity of the object, and a third elastic air bag is used for actively and periodically sucking in hot air and sucking out cold air to continuously, effectively and comprehensively preserve freshness of the object.

Description

technical field [0001] The invention relates to the field of heat preservation devices, in particular to a multifunctional ice bag heat preservation box. Background technique [0002] At present, due to the increasing number of people traveling and picnicking and the frequency is steadily increasing, and when traveling or picnicking, it is often necessary to carry ingredients and drinks for consumption on the way of travel or during picnics. In order to ensure that the ingredients and drinks are fresh and not deteriorated , you need to carry an incubator, put the ingredients and drinks in the incubator, and put a bagged ice bag in the incubator to lower the temperature in the incubator, thereby keeping the ingredients and drinks fresh. However, the bagged ice packs put into the incubator box are not effectively fixed, and are placed irregularly in the box. The function is not fully released, so it cannot keep fresh to the same degree for all items in the box, which may easi...

AI Technical Summary

Problems solved by technology

However, the bagged ice packs put into the incubator box are not effectively fixed, and are placed irregularly in the box. The function is not fully released, so it cannot keep fresh to the same degree for all items in the box, which may easily cause partial deterioration of some ingredients; and the incubator does not have the function of shock absorption, and items such as fruits are often damaged by shocks such as bumps
