Explosion-proof vending and refueling all-in-one machine and arrangement method thereof

The invention discloses an explosion-proof vending and refueling all-in-one machine, which is arranged in a gas station, and comprises a machine housing and an oiling machine, a vending system and a collection and payment system, which are arranged on the machine housing. The vending system comprises a refrigerating system, a goods channel, a goods channel propelling mechanism and a storage cabinet, and is characterized in that the height from the refrigerating system and the goods channel propelling mechanism to the ground of the gas station is not smaller than the safety concentration height, and the safety concentration height is the minimum height where the all-in-one machine can be located in the safety oil gas concentration environment where the gas station is located. According to the scheme, the refrigerating system and the goods channel propelling mechanism which possibly generate electric sparks or dangerous temperature are arranged above the safety concentration height; compared with a method for i
