Anti-freezing and sterilizing device for vehicle

The utility model relates to the technical field of disinfection equipment, and particularly provides an anti-freezing disinfection device for a vehicle. Comprising a disinfectant storage tank and a solvent storage tank, the disinfectant storage tank and the solvent storage tank are connected with a diluent tank through a disinfectant pipeline and a solvent pipeline respectively, and metering valves are arranged on the disinfectant pipeline and the solvent pipeline and used for adjusting the flow of disinfectant or solvent introduced into the diluent tank; a sprayer is arranged at the tail end of an outlet pipeline of the diluent tank and used for spraying diluent; and a pipeline blowing device is arranged on an outlet pipeline of the diluent tank. The problems that in the prior art, manual vehicle disinfectant preparation is high in cost and risk, unstable in error and high in labor intensity, potential safety hazards exist, and in order to prevent a disinfectant motor from freezing, a heat tracing band is o
