The indoor air of walk-in inhales the adsorption solution of preservation box through first air pump in, through adsorption and the filtration of adsorption solution, forms clear air, and the gathering is at the upper portion cavity of preservation box, and when more and more gaseous gathering in the upper portion cavity of preservation box, gaseous certain pressure that forms, then the diffusion flow arrives in the walk-in.
In order to make the air in the refrigerating chamber fresher, as an improvement, the preservation box is connected with a second air transmission pipe, the input end of the second air transmission pipe is communicated with the air outside the box body, and the output end of the second air transmission pipe is also positioned in the adsorption solution in the preservation box; and a second air pump is arranged in the second air transmission pipe and used for sucking air outside the box body into the adsorption solution of the preservation box.
