The working principle of the utility model is as follows:

(1) when the tableware needs to be taken and placed or the tableware needs to be independently disinfected, as shown in fig. 4 and 5, in the first state, the pipe cover 3 is covered on the air outlet 122 and extends into the mounting box 13, the folded edge 32 of the pipe cover 3 is tightly sealed and attached to the inner wall of the liner 12 close to the air outlet 122, the bulge 62 on the baffle 6 is inserted into the air outlet 131 so that the baffle 6 covers the air outlet 131 to block the steam exhaust channel, on one hand, the disinfection lamp tube 2 can be prevented from being damaged when a user takes and places the tableware, on the other hand, the external air can be prevented from entering the disinfection cavity 121 to pollute the disinfection cavity 121 when the disinfection lamp tube 2 works independently, and meanwhile, the inner wall of the pipe cover 3 can reflect and focus disinfection light to the tableware, so that the disinfection effect is enhanced;

(2) when the tableware needs to be disinfected and dried and the disinfection cavity is exhausted, the disinfection lamp tube 2, the heating part 4 and the driving part 53 are started, the slide rod 54 drives the baffle 6 to move backwards, the baffle 6 drives the disinfection lamp tube 2 to synchronously descend to a proper height relative to the cabinet body 1 along with the tube cover 3 through the flexible belt 52, as shown in fig. 6, in the second state, the tube cover 3 is exposed out of the mounting box 13 and is positioned in the disinfection cavity 121, because the disinfection lamp tube 2 moves towards the tableware, the distance between the disinfection lamp tube 2 and the tableware is shortened, the disinfection light intensity is enhanced along with the shortening of the radiation distance, the disinfection effect on the tableware can be enhanced, and meanwhile, the disinfection light can be reflected and focused on the tableware by the inner wall of the tube cover 3, so that the disinfection effect is enhanced; the baffle 6 does not cover the air outlet 131 so as to conduct the exhaust channel, according to the chimney effect in the heat exchange principle, air generates the difference of air density due to the temperature difference, thereby forming pressure difference, hot gas rises, and water vapor in the disinfection cavity 121 enters the mounting box 13 through the flow guide channel 33 and the air outlet 122 in sequence, and is finally exhausted to the outside atmosphere through the air outlet 131 and the exhaust port 112 in sequence;

because the tube cover 3 is flexibly connected with the bottom end of the flexible belt 52, on one hand, the tube cover 3 and the disinfection lamp tube 2 can vertically droop at the bottom end of the flexible belt 52 in a state without air flow disturbance and can swing relative to the cabinet body 1 along with the flexible belt 52 under the action of hot air flow generated by heating of the heating element 4 to form dynamic radiation/reflection disinfection light, which is beneficial to further expanding the irradiation range and improving the disinfection effect; on the other hand, when the tube cover 3 and the disinfection lamp tube 2 fall down and the users cannot return normally, the users take and place the tableware, if the tube cover 3 is touched, the tableware is in soft contact with the tube cover 3, the top of the tube cover 3 is shaken and swung, the disinfection lamp tube 2 can be protected from being touched by the tableware due to rigid connection with the inner container 12 and damaged, and in addition, the users can be prompted to take control actions to move the disinfection lamp tube upwards and return the disinfection lamp tube;

because the flow guide channel 33 is formed between the outer side wall of the tube cover 3 and the inner wall of the inner container 12 close to the air outlet 122, the aperture of the flow guide channel 33 is gradually reduced along the flowing direction of the air flow, and the negative pressure range is larger when the aperture of the inlet of the flow guide channel 33 is large, the water vapor in the disinfection cavity 121 can be conveniently and quickly sucked into the mounting box 13;

in the disinfection process, the tube cover 3 and the disinfection lamp tube 2 can be driven to move up and down in a reciprocating manner by the driving piece 53 to form dynamic radiation/reflection disinfection light, so that the irradiation range can be further expanded, and the disinfection effect can be improved;

after the disinfection, the drying and the steam exhaust are finished, the tube cover 3, the disinfection lamp tube 2 and the baffle 6 are driven by the driving piece 53 to reset to the first state.
