The diameter of the movable sterilization device is 20cm, the light-emitting angle is 150 degrees, and the radiation intensity of the first ultraviolet light source 6 is equal to 2000 muW/cm2For purposes of illustration:
considering factors such as moving corners or obstacles of the mobile sterilization device, the diameter of an irradiation surface is 24cm, and the irradiation area S1 of a single light source is pi × r2＝3.14×(78.14÷2)2≈47.93cm2；
Wherein r is the irradiation radius of a single light source;
irradiation area S ═ pi × R of mobile sterilization device2＝3.14×(24÷2)2≈452.16cm2；
Wherein R is the radius of the irradiation surface of the mobile sterilization device;
this results in the number of light sources required being: the number of light sources is equal to the irradiation area of the mobile sterilization device and the irradiation area of a single lamp bead is equal to 452.16 and 47.93 which is approximately equal to 9.4

Irradiation dose K (. mu.Ws/cm)2) UVC radiation intensity I (μ W/cm)2) × irradiation time t(s)
＝2000×6＝12000μWs/cm2。
Thus, with 12 first UV sources according to the present application, a movement speed of 4cm/s, the radiation intensity of said first UV sources being equal to 2000. mu.W/cm2The resulting irradiation dose was 48000. mu.Ws/cm2The irradiation dose is 12000 mu Ws/cm higher than the irradiation dose capable of killing 99 percent of bacteria and viruses2Therefore, the mobile sterilization device can kill most of bacteria and viruses, and can sterilize by adopting the parameters under the condition of good surrounding environment.
When the machine is moving at a speed of 1cm/S, the dose of radiation at this time is calculated as:
moving sterilizer irradiation time t is irradiation diameter ÷ moving sterilizer speed is 24cm ÷ 1cm/s ÷ 24s
Irradiation dose K (. mu.Ws/cm)2) UVC radiation intensity I (μ W/cm)2) × irradiation time t(s)
＝2000×24＝48000μWs/cm2
Thus, with 12 first UV sources according to the present application, a movement speed of 1cm/s and a radiation intensity of said first UV sources equal to 2000. mu.W/cm2The resulting irradiation dose was 48000. mu.Ws/cm2The irradiation dose of 46200 muW/c capable of killing over 99 percent of bacteria and virusesm2Therefore, the mobile sterilization device can kill more than 99% of bacteria and viruses.
