100,000uW.s/cm2÷70uW/cm21429s ≈ 24 minutes;
the time required for killing genetic material and propagules under the same radiation intensity is:
10,000uW.s/cm2÷70uW/cm2143s ≈ 2.4 minutes;
two inferences can be drawn from this:
1. the ultraviolet killing effect is a function of illumination and time, and the effect of adjusting the disinfection intensity can be achieved by changing the irradiation time or changing the irradiation intensity.
2. After 99.99% of microorganisms are killed by adopting the standard dose, the increase of the number of residual bacteria can be effectively inhibited only by using the bacteriostatic dose with the disinfection intensity of about one tenth to destroy the genetic structure and propagules of the microorganisms.
Therefore, the utility model discloses a radiation dose is adjusted to the mode when control ultraviolet irradiation is long, forms the disinfection mode of two different intensities, and "standard disinfection" and "antibacterial disinfection" promptly; the default work flow is sterilization and bacteriostasis, namely, the sterilization is carried out at the rate of 100,000uW.s/cm2The standard radiation dose of the Chinese medicinal composition kills 99.99 percent of viruses and bacteria, and then enters a bacteriostatic disinfection mode at intervals of 10,000uW.s/cm2The bacteriostatic dose of radiation destroys its genetic material and propagules, and minimizes the growth of residual microorganisms to achieve an extended shelf lifeThe purpose is.
The utility model discloses an operation mode does:
1. after covering the articles to be disinfected by the shielding cover 1, the power supply is switched on, and the power switch is turned on.
2. Pressing the start-stop key 3-32, turning on the ultraviolet lamp tube 2-2, the ozone generator 2-3 and the micro fan, radiating and diffusing ultraviolet rays and ozone below the rotary table 2-1 to perform standard disinfection on target objects, and driving the rotary table 2-1 to slowly swing by the servo motor 2-6 so as to reduce the condition that an ultraviolet light source is shielded.
3. The default flow of the utility model is that the sterilization is carried out before the bacteriostasis, namely, the 'standard disinfection' is automatically carried out after the 'standard disinfection' is finished, and the 'antibacterial disinfection' program is circulated until the start-stop key 3-32 is pressed down.
4. After the start-stop key 3-32 is pressed, the whole machine returns to a standby state to wait for next disinfection.
The utility model discloses a mode when adjusting ultraviolet irradiation time controls accumulative radiation dose, forms the disinfection mode of two different intensities, and the first is standard disinfection mode, and disinfection unit is the start in succession promptly to reach 100,000uW.s/cm2The standard radiation dose of (1) kills 99.99% of viruses and bacteria; the second is a bacteriostatic disinfection mode, i.e. the disinfection unit 2 is intermittently powered on in a sleep-on-re-sleep mode with 10,000uW.s/cm per power-on period2The bacteriostatic dose of (A) destroys the genetic material and propagules of the microorganism, and suppresses the reproductive growth of the microorganism to a minimum level.
The work flow diagram shown in fig. 5 demonstrates the operation method and the disinfection process of the present invention:
1. when the mode key 3-31 is pressed, the mode pointer will change in three numbers of 0, 1 and 2, and the LED indicating lamp group 3-2 gives the corresponding prompt.
2. When the strength key 3-33 is pressed, the strength pointer is changed from 0 to 15.
3. After the start-stop key 3-32 is pressed, the disinfection process formally starts, the MCU in the control box 3-1 enters a corresponding program path according to the mode pointer, and the disinfection unit 2 is controlled to execute various actions until the whole disinfection process is completed.
As can be seen from the flow chart shown in FIG. 5, after the disinfection process has started and the timer parameters have been loaded, the MCU selects the following three different program paths according to the mode pointers:
1. when the mode pointer is 0, the normal sterilization process is executed, and the sterilization unit 2 is turned off after the timing is ended, and the state returns to the standby state.
2. And (3) executing a 'standard disinfection' program, and executing a 'bacteriostatic disinfection' program in a circulating way until the start-stop keys 3-32 are pressed again, and then executing the power-off operation to return to the standby state.
3. And (3) skipping the 'standard disinfection' program by the mode pointer 2, directly and circularly executing the 'bacteriostatic disinfection' program, closing the disinfection unit 2 until the start-stop key 3-32 is stopped, and returning to the standby state.
The length of the ultraviolet light source radiation time is determined by the timing parameters loaded during standard disinfection, and the length of the ultraviolet light source radiation time is formed by adding a correction quantity to the standard disinfection reference time, wherein the correction quantity is obtained by an intensity pointer lookup table and is used for compensating the dosage error caused by light source aging, irradiation distance and angle change, and the value range of the correction quantity is 0-50% of the reference time.
In the 'bacteria inhibiting and disinfecting' program, the timer parameter is formed by adding the correction quantity to the 'bacteria inhibiting and disinfecting' reference time length, in addition, a dormancy timer is added, the dormancy time length loaded by the timer is the interval time between two times of disinfecting radiation, the value range is 1-12 hours, and the timer has the function of inhibiting the growth of residual microorganisms by the radiation dose as low as possible, so that the purpose of prolonging the shelf life is realized.
