Example 8
Referring to fig. 5, fig. 5 is a cross-sectional view of the present embodiment.
The embodiment provides an ultraviolet sterilizer, which comprises a sterilizer case 1 and a frame 2, wherein the sterilizer case 1 is fixedly arranged on the frame 2; an ultraviolet lamp 3 is arranged in the sterilizing cabinet 1, and a reflecting cover 4 is arranged on the periphery of the ultraviolet lamp 3; the sterilizing cabinet 1 is provided with an air inlet and an air outlet, and a fan 5 is arranged in the sterilizing cabinet 1; the reflection cover 4 is provided with a hydroxyl radical coating; the air inlet is arranged at the lower end of the sterilizing cabinet 1, and the air outlet is arranged at the upper end of the sterilizing cabinet 1; the reflecting cover 4 is provided with a reflecting sheet 6; the reflecting sheet 6 is arranged on the inner side of the reflecting cover 4 in a surrounding way; the bottom of the sterilizing cabinet 1 is provided with a filtering device; the filtering device comprises a filtering box with upper and lower openings, and a filtering plate is arranged in the filtering box; a plurality of filter plates are stacked in the filter box, and gaps exist between adjacent filter plates; the filtering device further comprises a rotating frame 10, two fixing frames 11 are fixedly arranged on the rotating frame 10, and openings are formed in the side faces of the fixing frames 11; the rotating frame 10 is rotatably sleeved with the frame 2. This embodiment is substantially identical to embodiment 1, with the main differences: a temperature sensor is arranged in the sterilizing cabinet 1, and a temperature adjusting device is arranged at the air inlet. Ultraviolet disinfection is under different air environment, and disinfection effect is different, and temperature regulation equipment can cooperate temperature-sensing ware to adjust air temperature. The radiation output of the ultraviolet lamp 3 of the ultraviolet sterilizer is influenced by the ambient temperature, and the sterilizing ultraviolet rays radiated by the ultraviolet lamp 3 at the ambient temperature of 40 ℃ are stronger. Generally, ultraviolet rays have a strong bactericidal effect at room temperature of 20 to 35 ℃. As the temperature decreases, the output of ultraviolet rays decreases; the ultraviolet radiation is absorbed and output is reduced due to the excessively high temperature. Most microorganisms are sensitive to ultraviolet rays at low temperature, and the low temperature can influence the output intensity of the ultraviolet lamp 3, and the output intensity of some lamp tubes at 4 ℃ is only 20-30% of that at 27 ℃. The resistance of bacteria increases when the temperature is reduced, the ultraviolet sterilization effect is weakened, and the sterilization effect is lost when the temperature is lower than 0 ℃, so that the sterilization effect is affected. Therefore, too high or too low a temperature has an influence on the sterilizing effect of ultraviolet rays.
Meanwhile, as the water molecules can absorb ultraviolet rays, the penetrating power of the ultraviolet rays can be reduced when the air humidity is high, the disinfection effect is reduced, when the air temperature is 24 ℃, the flow rate is 0.472m/s, the relative humidity is 35-85%, and the radiation intensity of the ultraviolet lamp 3 is inversely proportional to the air moisture content. When the humidity is 70%, 80%, 90%, the radiation intensity is increased by 50%, 80%, 90%, respectively, to achieve the same effect. Researches show that the indoor humidity is below 55% and the sterilizing effect of the circulating wind ultraviolet air sterilizer is not obviously affected. It is understood that the low temperature environment is better than the high temperature environment, the dry climate is better than the wet climate ultraviolet air disinfection effect, and the sterilization efficiency can be reduced to 1/3 of the original sterilization efficiency when the relative humidity is increased from 33% to 56%. Therefore, the irradiation time of the ultraviolet lamp 3 of the ultraviolet sterilizer should be increased when the humidity is high.
Further, the temperature regulating device comprises a throttling expansion device, an evaporator, a compressor and a condenser and is connected with the evaporator through a sealing pipe, and the temperature regulating device works through the compressor to compress low-temperature low-pressure refrigerant into high-temperature high-pressure gaseous refrigerant which enters the condenser; the high-temperature high-pressure gaseous refrigerant enters a condenser, heat of the high-temperature high-pressure gaseous refrigerant is radiated into the air through heat exchange of the condenser, the refrigerant is liquefied to become medium-temperature high-pressure liquid refrigerant, and the medium-temperature high-pressure liquid refrigerant enters a capillary tube; the medium-temperature high-pressure liquid refrigerant enters a capillary tube for throttling, becomes low-temperature low-pressure refrigerant, and enters an evaporator; the low-temperature low-pressure refrigerant enters an evaporator, is evaporated into low-temperature low-pressure gaseous refrigerant through heat exchange (heat absorption), and enters a compressor. The evaporator is arranged on the frame 2 to cool the filter box close to the inlet, so that overheated air can be cooled, and the temperature of the air to be disinfected is controlled to be 20-35 ℃ by adjusting the air suction speed in cooperation with the rotating speed of the fan 5, so that the disinfection efficiency is ensured; the condenser is arranged on the frame 2 to heat and dry the filter box at the inlet of the other filter box. It will be appreciated that the temperature regulating device may be provided inside the housing 2.
Further, a groove 12 is arranged on the frame 2, the filter box can rotate into the groove 12 through the rotating frame 10, and the condenser is arranged on the periphery of the groove 12; a vent hole 13 is arranged above the groove 12 and is used for radiating hot air; the vent holes 13 and the sterilizing cabinet 1 are arranged on two opposite side surfaces of the frame 2. An auxiliary bracket 14 can be arranged on the frame 2 and penetrates through the rotary frame 10 to contact the ground.
In summary, an embodiment of the present application provides an ultraviolet sterilizer, which includes a sterilizer casing 1 and a frame 2, wherein the sterilizer casing 1 is fixedly arranged on the frame 2; an ultraviolet lamp 3 is arranged in the sterilizing cabinet 1, and a reflecting cover 4 is arranged on the periphery of the ultraviolet lamp 3; the sterilizing cabinet 1 is provided with an air inlet and an air outlet, and a fan 5 is arranged in the sterilizing cabinet 1. The fan 5 sucks external air into the sterilizing cabinet 1 through the air inlet, and sterilizes and disinfects the air in the sterilizing cabinet 1, so that unnecessary side effects on the outside in the sterilizing process are avoided. The ultraviolet lamp 3 arranged in the sterilizing cabinet 1 disinfects the air in the sterilizing cabinet 1, the ultraviolet lamp 3 utilizes the ultraviolet rays emitted by the mercury lamp to realize the sterilizing function, and ultraviolet sterilization is to destroy and change the DNA (deoxyribonucleic acid) structure of microorganisms through the irradiation of the ultraviolet rays, so that bacteria die or cannot reproduce the offspring immediately, and the aim of sterilization is fulfilled. The air after disinfection in the disinfection cabinet 1 passes through the air outlet to discharge clean air. The reflecting cover 4 is arranged on the periphery of the ultraviolet lamp 3, and the ultraviolet light emitted by the ultraviolet lamp 3 outwards is reflected inwards again through the reflecting cover 4, so that the energy of the ultraviolet light in the sterilizing cabinet 1 is increased, the sterilizing efficiency on air is increased, and the sterilizing efficiency on air is improved; meanwhile, the arrangement of the reflecting cover 4 further prevents ultraviolet rays from penetrating through the outer shell of the disinfection cabinet 1 to cause damage to the outside.
