As shown in fig. 1 to 2, an intelligent disinfection lighting and deodorization system comprises a relay K1, a relay K2, a relay E1, an MCU controller for controlling the relay K1, the relay K2 and the relay E1, and a normally closed switch SB, wherein the normally closed switch SB is connected in series with the relay K1, the relay K2 and the relay E1 which are connected in parallel, the MCU controller is respectively connected with the relay K1, the relay K2 and the relay E1, the rear ends of the relay K1 and the relay K2 are respectively connected in series with a disinfection component XS1 and a deodorization component XS2, the rear end of the relay E1 is connected in series with the lighting component E L1 and the lighting component E L2 which are connected in parallel, the lighting component E L1 and the lighting component E L2 are lamps, and the whole system is externally connected with a power supply AC 110V-220V.

The normally closed switch SB is a rocker self-recovery switch or a contact normally closed switch, and in a default state, the normally closed switch SB is in an open state, is in a closed state after being pressed down, and is recovered to be in an open state after being released.

The disinfecting assembly XS1 is an ultraviolet lamp, and the deodorizing assembly XS2 is an ozone generator and is used for sterilizing and deodorizing the surrounding environment;

the relay K1, the relay K2 and the relay E1 are normally-open relays and are not affected by a normally-closed switch SB, the relay E1 is a normally-open circulating relay and only controls a lighting assembly, an output circuit of the relay E1 is in a closed state in a default state, when the normally-closed switch SB performs 'opening-closing' operation once, the lighting assembly E L is opened, the lighting assembly E L2 is closed, when the normally-closed switch SB performs 'opening-closing' operation once again, the lighting assembly E L is closed, the lighting assembly E L is opened, and when the normally-closed switch SB performs 'opening-closing' operation once again, all output circuits of the relay E1 are closed.
