As shown in fig. 1, the present embodiment provides an insulation container 10, which has an insulation function, and can insulate the temperature of water stored therein, so that the water is in a suitable temperature range for cooling operation within a certain period of time, thereby better cooling operation.

Specifically, the thermal container 10 is used for containing liquid. Specifically, in the present embodiment, the heat-insulating container 10 is used for storing a liquid for cooling, such as a clean water source, for performing a cooling operation on a human body by using the clean water source. However, the liquid provided in this embodiment is not limited to be a clean water source, and may also be applied to a disinfection occasion, where the liquid may be 75% alcohol, and may be specifically selected according to an actual application scenario, and this is not specifically limited in this embodiment. In addition, the liquid stored in the thermal container 10 should be at a liquid temperature suitable for the cooling operation.

Further, the thermal insulation container 10 includes: the container comprises a housing top wall 110, a housing bottom 130 and a housing side wall 120 arranged between the housing top wall 110 and the housing bottom 130 and used for connecting the housing top wall 110 and the housing bottom 130 respectively, wherein the housing top wall 110, the housing bottom 130 and the housing side wall 120 together form a container 10 with an inner cavity 140, and the inner cavity 140 is used for containing liquid at a proper temperature required for cooling operation.

Further, the container 10 has a thermal insulation function, embodied in particular by: the housing sidewall 120 includes an inner sidewall 1201 and an outer sidewall 1202 covering the inner sidewall 1201, wherein a first gap 1203 between the outer sidewall 1202 and the inner sidewall 1201 is filled with a thermal insulation material 1204, or the first gap 1203 between the outer sidewall 1202 and the inner sidewall 1201 is in a vacuum state (a schematic diagram of the embodiment is not shown, and fig. 1 may be obtained by removing the thermal insulation material 1204), so that the temperature of the liquid in the inner cavity 140 of the container 10 is not transmitted to the outer sidewall 1202 through the inner sidewall 1201, thereby well avoiding the temperature of the housing sidewall 120 for heat dissipation, ensuring that the temperature of the liquid in the inner cavity 140 can be kept near an initial temperature value within a certain time, and preventing the temperature of the liquid from dropping to make the liquid unsuitable for cooling operation. The heat insulating material 1204 may be any of glass fiber, asbestos, rock wool, silicate, and aerogel felt, as long as it can perform the function of heat insulation and preventing heat diffusion, and this embodiment is not particularly limited.

In summary, the thermal insulation container 10 provided in this embodiment has a thermal insulation function, and can perform long-term thermal insulation on the liquid stored therein, so as to be used for cooling operation. In addition, the housing sidewall 120 has two layers, which are an inner sidewall 1201 and an outer sidewall 1202, respectively, and a vacuum state is formed between the inner sidewall 1201 and the outer sidewall 1202 or a heat insulating material is filled between the inner sidewall 1201 and the outer sidewall 1202, so that heat dissipation of the liquid stored in the container 10 can be better prevented, the heat preservation time can be prolonged, and the temperature of the liquid in the container 10 can be further ensured.

The temperature of the liquid in the inner cavity 140 can be kept near the initial temperature value within a certain time, and the liquid temperature is prevented from being reduced so that the liquid is not suitable for cooling operation.

In addition, in this embodiment, the top wall 110 of the housing extends to a side away from the inner cavity 140 to form a connecting portion 150 having a hollow structure 1501, the hollow structure 1501 is communicated with the inner cavity 140, an external connecting nozzle (not shown in the figure) is provided on an outer wall of the connecting portion 150, so that the liquid in the thermal insulation container 10 is sprayed out through the connecting portion 150, so that the liquid in the thermal insulation container 10 can be gasified into steam for spraying to a portion of a human body requiring cooling, and the nozzle is used for spraying the liquid in the thermal insulation container 10 in a mist state, so as to meet the requirement of an actual cooling operation.

Specifically, if only the water at the proper temperature required for the cooling operation needs to be stored in an insulated state, the insulated container 10 shown in fig. 1 can be selected, which can be used only for storing the liquid in an insulated state. If the temperature reduction operation is convenient, a nozzle may also be directly installed on the connecting portion 150 of the thermal insulation container 10 to atomize and spray the liquid for performing the actual temperature reduction operation, and the specific structure of the thermal insulation container 10 may be selected according to the actual use scene, which is not specifically limited in this embodiment.

In this embodiment, the gap value range of the first gap 1203 or the second gap 1103 is between 2-5mm, and it is sufficient that the gap can be used to provide a space for filling the thermal insulation material 1204, and this embodiment is not particularly limited thereto.

In this embodiment, for the thermal insulation container 10, the bottom 130, the inner top wall 1101, the outer top wall 1102, the inner side wall 1201, and the outer side wall 1202 of the casing are all made of thermal insulation materials for insulating liquid in the thermal insulation container 10, and the specific thermal insulation material may be an organic thermal insulation material, such as polyurethane foam, polystyrene board, phenolic foam, or other materials, which is specifically selected according to actual needs, and this embodiment is not specifically limited thereto.
