[0037] The inventor of this application found in the design research of air environment machine products that Figure 1 As shown, the air environment machine will lay out the fresh air structure by increasing the length of the air outlet side 1, and the later disassembly and maintenance of the fresh air structure will also be carried out on the air outlet side 1. The specific disassembly process is to first unscrew the countersunk screws 2 on the air outlet side 1, and then remove the fresh air fan 3 from the air outlet side 1. In this process, on the one hand, due to the narrow disassembly and maintenance space, maintenance personnel are required to find the correct screw hole position in the narrow space during disassembly and maintenance, which makes disassembly and assembly difficult; on the other hand, the length of the air outlet grille is increased, which increases the overall volume of the air environment machine. In addition, when the air environment machine is installed, a certain space must be reserved with the ceiling or wall, so that the fresh air fan 3 can be disassembled and removed during later disassembly and maintenance. Based on this, the inventor of the present application proposed an air environment machine with a design concept that disassembly and maintenance are carried out on the return air side, which can effectively solve the above-mentioned problems currently existing in the air environment machine. The embodiment of the air environment machine is described in detail as follows.
