[0001] The present invention relates to the technical field of cleaning and disinfection vehicles, in particular to a multifunctional cleaning and disinfection vehicle. Background Art

[0002] Decontamination fire trucks are the primary equipment used by fire brigades to decontaminate hazardous chemical incidents. They are used to decontaminate and disinfect weapons, ground, and fortifications. Currently, fire brigades employ decontamination trucks primarily equipped with decontamination tanks, heaters, and hot water or decontamination agent sprayers for decontamination of hazardous chemical incidents. However, decontamination trucks struggle to simultaneously perform both disinfection and decontamination at the scene. After disinfection, decontamination requires the tanks to be completely drained, rinsed, and refilled with clean water before decontamination can proceed. This wastes decontamination fluid and reduces on-site operational efficiency.

[0003] Summary of the Invention

[0004] Based on this, it is necessary to provide a multifunctional cleaning and disinfection vehicle that can avoid waste of cleaning fluid and improve on-site operation efficiency in response to the above technical problems.
