Embodiment 1

[0024] Such as Figure 1 to Figure 3 As shown, a portable cold box includes a box body 1 with an opening and a cover body 2 for blocking the opening. The box body 1 includes an inner waterproof layer 13, a first thermal insulation layer 12 and an outer shell 11. The inner wall of the box body 1 is fixed and useful. For the reaction box 14 where the dry ice is placed, the cover 2 is provided with an exhaust fan 21 and an exhaust fan hole, and the exhaust fan 21 is installed on the exhaust fan hole through an exhaust fan frame 24 . The portable cold box has a refrigeration state and a refrigeration state. In the refrigeration state, the dry ice is sublimated in the reaction box 14, and the exhaust fan 21 rotates to discharge the gas produced by the sublimation of the dry ice. In the refrigeration state, the exhaust fan 21 stops rotating.

[0025] The cover body 2 is provided with a battery box 23, the battery box 23 is electrically connected with the exhaust fan 21, a dry batter...

Abstract

The invention discloses a portable refrigerated container and relates to the technical field of refrigeration. The portable refrigerated container comprises a container body and a cover body. The container body is provided with an opening. The container body comprises an inner waterproof layer, a first heat preservation layer and a shell. A reaction box used for accommodating dry ice is fixed to the inner wall of the container body. An exhaust fan is arranged on the cover body. The portable refrigerated container has a refrigerating state and a cold storage state. In the refrigerating state, the dry ice sublimes in the reaction box, the exhaust fan rotates, and gas generated during sublimation of the dry ice is exhausted; and in the cold storage state, the exhaust fan stop rotating. The portable refrigerated container is simple and reliable in structure and can achieve refrigeration outdoors.

Description

【Technical field】 [0001] The invention relates to the technical field of refrigeration, in particular to a portable cold box. 【Background technique】 [0002] When people travel or participate in outdoor activities, they often use boxes to carry some cold drinks for the purpose of relieving heat and cooling down. In the prior art, the prepared refrigerators only have the function of heat preservation, but cannot be refrigerated. Therefore, when people need to cool down some beverages and foods, they are often helpless when traveling or participating in outdoor activities. 【Content of invention】 [0003] In order to solve the above technical problem, the present invention provides a portable cold box, which has a simple and reliable structure and can realize refrigeration outdoors. [0004] In order to achieve the above object, the present invention adopts following technical scheme: [0005] A portable cold box, comprising a box body with an opening and a cover body to bl...
