The invention discloses a foam mixer of a self-service vehicle washing machine. The foam mixer comprises a shell, and the shell is internally provided with a mixing cavity. A water inlet connector, a water outlet connector and a foam inlet connector which are communicated with the mixing cavity are arranged on the shell, the water inlet connector and the water outlet connector are used for being connected with a water feeding pipe of the self-service vehicle washing machine, and the foam inlet connector is used for being connected with a foam feeding pipe of the self-service vehicle washing machine. A valve rod extending into an inner hole of the foam inlet connector is movably arranged on the shell, and a foam flowing gap is formed between the valve rod and the inner hole of the foam inlet connector. A sealing ring is arranged on the valve rod, and the valve rod is driven by a valve rod power device to enable the sealing ring and the inner hole to be in sealing fit or be separated. A foaming agent raw solution can be effectively mixed with fresh water through the foam mixer, and the service life of foaming agents in the self-service vehicle washing machine is prolonged accordingly; when the foam needs to be washed through fresh water, the fresh water can be rapidly fed, waiting time can be shortened, and the water can be saved.
