The technical scheme of the invention is further described below with reference to the accompanying drawings.

Referring to fig. 1-2, the vaporization device comprises a housing 1 having a hollow inner cavity 2, a feed inlet 3 and a discharge outlet 4 provided at the top of the housing 1, a hot air duct 5 extending into the hollow inner cavity 2 through the feed inlet 3, an atomizing nozzle 6 positioned in the hot air duct 5, a compressed air pipeline 7 and a hydrogen peroxide pipeline 8 respectively communicated with the atomizing nozzle 6, a finned tube 9 positioned below the hot air duct 5 in the hollow inner cavity 2, a first heating mechanism (not shown in the figure) for introducing high-temperature steam into the finned tube 9, a fan housing 10 with an upper end connected to the lower end of the hot air duct 5 and used for housing the finned tube 9, and a gap for allowing the hydrogen peroxide steam to flow upwards to the discharge outlet 4 is provided between the fan housing 10 and the inner surface of the housing 1.

In the present embodiment, the gap includes a first space 12 provided between the bottom of the hood 10 and the inner bottom surface of the housing 1, and a second space 13 provided between the outer peripheral portion of the hood 10 and the inner peripheral portion of the housing 1. Through this setting, the hydrogen peroxide vapor contacts the inner bottom surface of the shell 1 first and then upwards flows to the discharge port 4, so that condensed water is condensed on the inner bottom surface of the shell 1, and the hydrogen peroxide vapor upwards flows, thereby greatly reducing the condensed water carried when the hydrogen peroxide vapor upwards flows, and enabling the hydrogen peroxide vapor to be drier and relatively good in disinfection effect.

In this embodiment, the housing 1 is a heat-conducting housing 1 with a certain thickness, and the device further includes a first pipe 11 penetrating the housing 1, and a second heating mechanism (not shown in the figure) for introducing high-temperature steam into the first pipe 11. By this arrangement, the whole housing 1 is kept at a high temperature, further preventing the hydrogen peroxide vapor from generating condensed water in the upward flowing process, and ensuring the sterilization and disinfection effects.
