Detailed Description
At present, the common disinfection methods are divided into a physical method and a chemical method. The physical method mainly adopts a common ultraviolet lamp for irradiation, the ultraviolet light emitted by the ultraviolet lamp has a destructive effect on microorganism DNA, and when the irradiation dose reaches a certain degree, the microorganism is killed, thereby playing a role in disinfection. The chemical method mainly adopts chemical agents with the effect of killing microorganisms, and the microorganisms are killed through the toxic action of the agents, so that the disinfection effect is achieved.
The inventors have found that both of the above-mentioned sterilization methods have their drawbacks. For a common ultraviolet lamp irradiation method, the ultraviolet lamp has low sterilization efficiency due to the fact that the energy conversion efficiency of the ultraviolet lamp is only about 20% and the luminous intensity is weak, and the ultraviolet lamp generally needs to be irradiated for more than 30 minutes in a certain volume of space to achieve the effect of complete sterilization; meanwhile, since ultraviolet rays themselves are harmful to human bodies, they must be used in unmanned environments. For chemical agents, the chemical agents are harmful to human bodies, so that the chemical agents cannot be used under certain conditions, and more importantly, when the chemical agents are used for disinfection for a long time, part of living microorganisms can generate drug resistance and evolve into super microorganisms which are difficult to kill, so that the disinfection is more difficult.

So that the disinfection effect and efficiency are improved.
The inventor also finds that the ultraviolet module is an ozone-free electrodeless ultraviolet module and an ozone-generating electrodeless ultraviolet module; when a person exists, the ozone-free electrodeless ultraviolet module and the pulse strong light module work simultaneously to disinfect the air in the accommodating cavity; when nobody, lifting unit rises the pulse highlight module to the outside that holds the chamber, produces electrodeless ultraviolet module of ozone and pulse highlight module simultaneous working, disinfect to the air that holds intracavity portion and the outside air that holds the chamber simultaneously, realize the sterile mode of multiplex condition, strengthen the effect of killing to the microorganism greatly, the mutual replacement of pulse highlight module and ultraviolet module guarantees that the microorganism kill rate is high, does not have the residue, the post-production thing of killing is organic matter or water basically, harmless to the human body, make sterile process unrestricted.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
FIG. 1 is a schematic view of a disinfection apparatus according to an embodiment of the invention; fig. 2 is a distribution diagram of a pulse tube according to an embodiment of the invention.
Referring first to fig. 1, a sterilization device 100 includes: a containing cavity 101, a fan unit 102 and a sterilizing unit 103.
The air conditioner comprises an accommodating cavity 101, wherein an air inlet 104 and an air outlet 105 are arranged on the accommodating cavity 101;
a blower unit 102 located at the air inlet 104, for introducing external air into the interior of the accommodating chamber 101;
disinfecting unit 103 fixes hold the inside of chamber 101, including pulse highlight module 106 and ultraviolet module 107, pulse highlight module 106 is located the top of ultraviolet module 107, be used for right hold the inside air in chamber 101 and carry out disinfection treatment, the air after the disinfection is followed air outlet 105 discharges hold the outside of chamber 101.
In this embodiment, the combination of the pulsed strong light module 106 and the ultraviolet module 107 is utilized to sterilize the air outside the accommodating cavity 101, so as to greatly improve the sterilization efficiency and shorten the sterilization time, and thus the sterilization device 100 has a wider application range, because the pulsed strong light module 106 can generate strong light with an intensity several ten thousand times higher than that of a common ultraviolet lamp in a unit time, and the strong light can complete the killing effect on microorganisms in a very short time, and simultaneously, because the generated energy is large enough to destroy the microorganism structure, the killing of the microorganisms is thorough, and the light revival problem cannot occur; the ultraviolet module 107 can kill microorganisms directly while the high-intensity pulse light module 106 sterilizes the microorganisms, and the ultraviolet module and the high-intensity pulse light module are combined with each other, so that the final disinfection effect and efficiency are greatly improved, and the disinfection device 100 has a wide application range.
Referring to fig. 2, in the present embodiment, the high pulse light module 106 is a pulse tube.
In other embodiments, the pulsed intense light module 106 can also be a combination of a pulser and a pulse tube.
The pulse tube is a lamp tube filled with rare gas, and can utilize electrodes to discharge instantly to excite the rare gas in a pulse form to emit high-intensity white light, wherein an ultraviolet light wave band can instantly kill microorganisms, so that the disinfection effect is achieved.
In this embodiment, the number of the pulse tubes is 9, including pulse tubes 1 to 9, the 9 pulse tubes are divided into 3 groups, including groups 1 to 3, the pulse tubes in each group are connected in parallel, and the pulse tubes in each group are connected in parallel.
In other embodiments, the number of pulse tubes can be any multiple of 3, since 3 lamps are primarily considered to be 120 ° angular, i.e. all the surrounding space can be irradiated from three angles, and the 3 lamps can be grouped together to emit light simultaneously. However, because the light-emitting interval of one group of pulse lamps is 1s, the effective light-emitting time is only 40-50 mus, and a plurality of groups can be configured at the same position, and each group alternately emits light to make up for the light-emitting interval time.
In this embodiment, the reason why the parallel connection is adopted between the pulse tubes is that: one pulse tube is out of order, the work of other pulse tubes is not influenced, and the whole equipment still has the sterilization effect.
In this embodiment, the wavelength of the light generated by the pulsed strong light module 106 is 200-850 nm, the pulse width is 40-50 μ s, and the intensity of the pulsed strong light module is higher than that of the pulsed strong light moduleIs 8.52 multiplied by 104μW/cm2～9.52×104μW/cm2。
In this embodiment, the pulse tubes are in a group of 3, and the problem of the ineffective light-emitting time interval of the pulse light can be solved by means of alternate light emission.
In this embodiment, the pulse tube produces light having an intensity of 8.52 x 104μW/cm2The intensity of the light is tens of thousands of times of that of the common ultraviolet lamp, and the effective irradiation dose per unit time is far higher than that of the common ultraviolet lamp. Therefore, the strong light generated by the pulse tube can complete the killing of the microorganisms in a very short time. In addition, because the sterilization energy of a common ultraviolet lamp is weak, part of microorganisms can not be completely killed after being irradiated, and the phenomenon of light revival exists, namely, the phenomenon that a small amount of microorganisms irradiated by ultraviolet light revival after being irradiated by visible light. The pulse tube generates high-intensity pulse strong light, and the energy is strong enough to destroy the structure of the microorganism, so that the microorganism can be thoroughly killed, and the problem of light revival cannot occur.
In this embodiment, the fan unit 102 is an axial fan; in other embodiments, the fan unit 102 may also be a centrifugal fan.
In this embodiment, the fan unit 102 is located in the accommodating cavity 101 and located at the air inlet 104.
In other embodiments, the blower unit 102 may also be located outside the accommodating cavity 101 and at the air inlet.
In this embodiment, the fan unit 102 is located at the bottom of the sterilizing unit 103, the fan unit 102 introduces the air outside the accommodating chamber 101 into the accommodating chamber 101, and the air sterilized by the sterilizing unit 103 is discharged outside the accommodating chamber 101 through the air outlet 105, so that the external air and the internal air of the accommodating chamber 101 are continuously circulated, thereby continuously sterilizing the air.
In this embodiment, the ultraviolet module 107 is an ozone-free electrodeless ultraviolet module 108 and an ozone-generating electrodeless ultraviolet module 109.
The ultraviolet module 107 includes a high-frequency generator (not shown), an energy coupler (not shown), and a lamp (not shown), where the high-frequency generator generates high energy, converts electric energy into a strong electromagnetic field, and introduces the high energy into the lamp through the energy coupler coupling, and the lamp has rare gas therein, so that the rare gas in the lamp is ionized and excited to a high energy state, and when the high energy state gas atoms return to a ground state, the ultraviolet module can radiate ultraviolet light.
In this embodiment, the ozone-free electrodeless ultraviolet module 108 can directly kill microorganisms in the air.
In this embodiment, the electrodeless ultraviolet module 109 for generating ozone can not only directly kill microorganisms in the air, but also react oxygen in the air to generate ozone, and the ozone further reacts to generate OH (hydroxyl radical) with stronger oxidizing property under the action of the strong pulse light, thereby killing the microorganisms.
In this embodiment, when the pulsed high light module 106 and the electrodeless ultraviolet module 109 for generating ozone work simultaneously, the killing of microorganisms is realized by using the strong oxidation effect of OH active radicals. Standard electrode potential for OH active free radicals is 2.8V, second only to F22.87V of (fluorine gas), very strong oxidizing power, and reaction rate constant of 10 with most organic substances6-108L/mol·s。
In this embodiment, in the state that the pulse high light module 106 and the ozone generating electrodeless ultraviolet module 109 work simultaneously, O in air2(oxygen) firstly, generating O according to formulas (1) and (2) under the action of ultraviolet light of an ozone-generating electrodeless ultraviolet module3(ozone).
O2+ hv (ultraviolet) → 2. O (oxygen free radical) (1)
O2+·O→O3 (2)
Under the action of the ultraviolet light of the pulsed strong light module 106, O3Excited according to formulas (3) and (4) to generate H2O2Further, OH may be formed, and OH may be formed from a part of water.
O3+H2O+hv→H2O2(Hydrogen peroxide) + O2 (3)
H2O2+hv→2·OH (4)
H2O + hv →. H (hydrogen radical) +. OH (5)
Under the action of water in the air, part of O generated by the electrodeless ultraviolet module for generating ozone is also generated into OH.
·O+H2O→2·OH (6)
When the microorganism contacts with OH active free radical, it will be oxidized and deactivated quickly, so as to further raise the sterilizing effect of the equipment. Based on the above principle, the sterilization device 100 is at 30m3Under the unmanned working condition, the disinfection time can be shortened to 5 minutes from 30 minutes of a common ultraviolet lamp to 30m3Under the working condition of people, the comprehensive disinfection of air can be realized within 10 minutes.
In this embodiment, the method further includes: the lifting assembly 110 is used for fixing the pulsed strong light module 106 inside the accommodating cavity 101 through the lifting assembly 110.
In this embodiment, the pulsed strong light module 106 is lifted to the outside of the accommodating cavity 101 or lowered to the inside of the accommodating cavity 101 by the lifting assembly 110, so as to achieve multi-condition disinfection.

In this embodiment, the lifting assembly 110 is welded to the accommodating chamber 101.
In other embodiments, the lifting assembly 110 is fixed to the accommodating chamber 101 by screws.
In this embodiment, under an unmanned working condition, the lifting assembly 110 is utilized to lift the pulsed light module 106 from the accommodating cavity 101, pulsed light is radiated to the surrounding environment, the electrodeless ultraviolet ozone generating module 109 works simultaneously, and the fan unit 102 draws in ambient air from the air inlet 104 of the accommodating cavity 101 and discharges the ambient air from the air outlet 105 of the accommodating cavity 101. In this mode, the pulsed strong light module 106 emits strong light with a wave band containing ultraviolet light and an intensity several tens of thousands of times of natural sunlight, and can directly kill microorganisms on the surface of the surrounding air and objects. The electrodeless ultraviolet module 109 for generating ozone continuously emits broadband ultraviolet light, wherein ultraviolet light with a certain wavelength, especially light with wavelength of 253nm, has a direct killing effect on microorganisms in the air pumped into the accommodating cavity 101, and the light with wavelength of 185nm can enable oxygen in the air to generate ozone. Ozone itself has strong oxidizing property, can kill microorganisms, and can quickly generate hydroxyl free radicals (. OH) after being irradiated by strong ultraviolet light, and the free radicals have stronger oxidizing property than ozone, so that the killing effect on the microorganisms can be greatly enhanced. In this mode, remote control can be achieved by a remote control module included in the disinfection apparatus 100.
In this embodiment, under a working condition of a person, the pulsed strong light module 106 operates in the accommodating chamber 101, the ozone-free electrodeless ultraviolet module 108 operates simultaneously, and the fan unit 102 draws in ambient air from the air inlet 104 of the accommodating chamber 101 and discharges the ambient air from the air outlet 105 of the accommodating chamber 101.

Under the working condition of large ventilation flow rate, the sterilizing effect of continuous luminescence of the ozone-free electrodeless ultraviolet module 108 can supplement the sterilizing effect of intermittent luminescence of the high-pulse light module, thereby improving the sterilizing efficiency.
In this embodiment, since the disinfection principle utilizes the combination of the pulsed strong light module 106 and the ultraviolet module 107, based on the light energy and the oxidation principle, the microorganism killing rate is high, no residue exists, and the product after killing is basically organic matter or water, which is harmless to human body and has a wide application range.
