[0022] The present invention is further described in detail below with reference to the accompanying drawings.

[0023] like Figures 1 to 4 As shown, the air duct structure of the disinfection cabinet includes:

[0024] The box body 1 and the inner liner 2 installed in the box body 1, the inner liner 2 is provided with a disinfection unit (not shown in the figure), which can be an ultraviolet generator, an ozone generator, a disinfection steam generator or other types of disinfection units; there is a gap 11 between the box body 1 and the inner liner 2. The box body and the inner liner and the assembly structure of the two are all conventional structures of disinfection cabinets.

[0025] An air outlet 21 is provided on the top surface of the inner container 2 , and an air return outlet 22 is provided on the rear wall plate of the inner container 2 near the bottom plate.

[0026] The air duct 3 is arranged in the gap 11 between the box body 1 and the inner tank 2; it is roughly "U"-shaped, with its upper section located in the gap between the top plate of the inner tank and the top plate of the box body, and its middle section located in the gap between the rear wall plate of the inner tank and the rear wall plate of the box body; the upper section and the middle section of the air duct 3 constitute a first air duct 31; the lower section of the air duct 3 is located in the gap between the bottom plate of the inner tank and the bottom plate of the box body, and the lower section of the air duct 3 is a second air duct 32 connected to the first air duct 31.

[0027] The wall of the upper section of the first air duct is provided with an air inlet 33 connected to the gap 11, and the terminal end of the second air duct 32 is the air outlet 34 of the air duct. The air outlet 34 is located below the door of the disinfection cabinet, exposed to the box body 1 and facing the ground in front of the disinfection cabinet.

[0028] The air outlet 21 and the air return outlet 22 are both connected to the first air duct 31 .

[0029] The fan 4 is arranged in the air duct 3, and is used to circulate the air in the inner container through the first air duct 3; or to extract the air in the surrounding environment through the gap 11 and blow the air flow to the ground around the disinfection cabinet. The fan 4 in this embodiment is arranged in the gap between the top plate of the inner container and the top plate of the box body, and is arranged near the exhaust port 21 and the air inlet 33. The fan 4 can be selected from any one of the existing technologies as needed.

[0030] The heating component 7 is arranged in the air duct, located in the first air duct between the fan 4 and the return air port 22, and is used to heat the air entering the first air duct 31. The heating component can be selected from any one of the prior art as needed.

[0031] The first valve is arranged in the upper air duct, and includes a first valve plate 5 and a first driving mechanism (not shown in the figure); wherein the first edge of the first valve plate 5 is rotatably connected to the outer wall of the inner tank top plate through a first rotating shaft (not shown in the figure), and the first driving mechanism drives the first valve plate 5 to rotate relative to the first rotating shaft. When the first valve plate 5 closes the air inlet 33, the air outlet 21 is opened; when the first valve plate 5 opens the air inlet 33, the air outlet 21 is closed.

[0032] The second valve is arranged between the return air port 22 and the middle air duct, and includes a second driving mechanism of the second valve plate 6 (not shown in the figure); wherein the first edge of the second valve plate 6 is rotatably connected to the outer wall of the rear wall plate of the inner tank through a second rotating shaft (not shown in the figure); the second driving mechanism drives the second valve plate 6, so that when the second valve plate 6 opens the return air port 22, the connection between the first air duct 31 and the second air duct 32 is closed; when the second valve plate 6 closes the return air port 22, the first air duct 31 and the second air duct 32 are connected.

[0033] The first driving mechanism and the second driving mechanism are both existing technologies, and any one of the existing technologies can be selected according to needs.

[0034] The temperature controller 8 is disposed in the first air duct 31 and is used to detect the air flow temperature in the first air duct 31 and control the operation of the heating component 7 .

[0035] When the disinfection cabinet enters the heating and drying program, the air in the inner tank needs to be heated; at this time, the control system of the disinfection cabinet controls the first drive mechanism and the second drive mechanism to work, drives the first valve plate and the second valve plate to rotate, opens the exhaust port and the return air port on the inner tank, closes the air inlet of the air duct and blocks the connection between the first air duct and the second air duct, such as Figure 2 As shown; the heating component and the fan are controlled to work at the same time; under the action of the fan, the air in the inner tank is discharged from the return air port, enters the first air duct, and returns to the inner cavity of the inner tank from the exhaust port after being heated by the heating component, heating and drying the items in the inner tank. When the temperature of the air flow passing through the thermostat is lower than the set value, the thermostat controls the heating component to work and heat the air flow in the first air duct. This cycle is repeated until the heating and drying process is completed.

[0036] When it is necessary to blow air to the ground around the disinfection cabinet to dry the ground, the control system of the disinfection cabinet controls the first driving mechanism and the second driving mechanism to work, drives the first valve plate and the second valve plate to rotate in opposite directions, closes the exhaust port and the return port on the inner tank, opens the air inlet of the air duct, and connects the first air duct and the second air duct. Figure 3 As shown; at the same time, the fan is controlled to work, and the heating component is controlled to work or not according to the user's instructions. Under the action of the fan, the ambient air enters the first air duct from the air inlet through the gap, is heated by the heating component and discharged from the air outlet, and blows to the ground around the disinfection cabinet or the surrounding environment to dry the ground or change the ambient temperature.
