Abstract
The utility model relates to a small ultraviolet air sterilizer for medical and domestic application. An air filter (3), a centrifugal fan (4), and a quartz ultraviolet sterilizing lamp (5) are installed in a box body (1) with an air return port (2) and an air supply port (6). The ultraviolet sterilizing lamp is installed in an outlet air channel or an inlet air channel of the centrifugal fan by parallel to the air flow direction. The ultraviolet irradiation time to air flows is increased, so that the number of sterilizing lamp tubes can be decreased correspondingly. In addition, the centrifugal fan driven by an external rotor electric motor with a built-in spiral casing is adopted, so that the size and the production cost of the ultraviolet air sterilizer are reduced greatly.
Description
This utility model relates to a kind of medical and household small-size ultraviolet air sterilizing apparatus.
Because carrying out and implementing of GB15982-1995 " medical disinfecting sanitary standard " and medical standards such as " medical clean operation department Building technology standards ", routine disinfection means such as Burdick lamp irradiation and the disinfecting drug that generally uses in the hospital at present sprays, fumigates, can't satisfy sterile air control requirement, only take air filtration to purify air-supply, could guarantee that the clean operation environmental air contains the bacteria concentration requirement.Air filtration purifies air-supply because of equipment investment and operating cost height, and operational management is strict, is difficult to large tracts of land and uses.A kind of ultraviolet air sterilizing apparatus appears on the market recently, it is that air filter, centrifugal blower and quartz ultraviolet ray sterilamp are housed in the casing that has return air inlet and air outlet, utilizes the high-intensity ultraviolet irradiation to kill the airborne planktonic bacteria of the sterilizing machine of flowing through.In this air sterilizing apparatus, quartz burner is perpendicular to that airflow direction arranges, and air-flow laterally skims over surface of the light tube, is subjected to ultraviolet irradiation time extremely short, is to guarantee Disinfection Effect, must adopt many tubes (4～6) arranged side by side; Add two again and split motor-driven centrifugal blower, thereby this air sterilizing apparatus volume is big, the production cost height is not suitable for family and uses.
The purpose of this utility model provides the small-sized ultraviolet air sterilizing apparatus of a kind of suitable hospital and family's use, and it can not only kill the planktonic bacteria in the space air quickly and efficiently, realizes air sterillization, and has characteristics such as volume is little, production cost is low.
The purpose of this utility model is achieved in that because the ultraviolet sterilization effect depends primarily on irradiation intensity, irradiation distance and irradiation time, so in the small-sized ultraviolet air sterilizing apparatus except adopting high strength quartz ultraviolet ray sterilamp, also the ultraviolet disinfection lamp fluorescent tube is contained in blower fan outlet or the import air channel, and being parallel to airflow direction arranges, make air-flow flow, accept ultraviolet irradiation time and can increase by 2～3 times along the fluorescent tube length direction; The air channel inwall that disinfecting tube is housed is a reflector, has further increased ultraviolet irradiation intensity, thereby uses a small amount of disinfection by ultraviolet light fluorescent tube, just can reach the bactericidal effect of many tubes arranged side by side in the existing ultraviolet air sterilizing apparatus.It in the small-sized in addition ultraviolet air sterilizing apparatus low-noise centrifugal fan that adopts the built-in outer rotor motor driven of spiral case, draught fan impeller directly is contained on the motor outer rotor, dwindle taking up room of blower fan (comprising motor), thereby reduced the volume and the production cost of ultraviolet air sterilizing apparatus significantly.According to the different instructions for uses of user, the profile of small-sized ultraviolet air sterilizing apparatus can be made desk-top or console model.
Compare with existing ultraviolet air sterilizing apparatus, this utility model can not only be killed the airborne bacterial strain that swims fast, control space air effectively and contain bacteria concentration, have simultaneously volume little, in light weight, save that raw material, production cost are low, series of advantages such as power saving, noise are low, especially be fit to the medium and small operating room of hospital, ward and family room and use, be the condition created that popularizes of ultraviolet air sterilizing apparatus.
Accompanying drawing is the structural representation according to the small-sized ultraviolet air sterilizing apparatus of desk-top and console model that the utility model proposes.Under the centrifugal blower entrance negative pressure attracted, space air entered blower fan (4) by return air inlet (2), air filter (3), sent into the outlet air channel after the supercharging through quartz ultraviolet ray sterilamp (6) radiation sterilization, sent into the room by air outlet (6).Quartz burner is to be parallel to airflow direction to be installed in the outlet air channel, and the air channel inwall is a reflector.Blower fan (4) is the low-noise centrifugal fan of the built-in outer rotor motor driven of spiral case, and draught fan impeller directly is contained on the outer rotor of motor.Have in the casing (1) of return air inlet (2) and air outlet (6), the electric control gear (not shown) also is housed.Air outlet (6) then is equipped with movable guide vane, is used for regulating air supply direction.
Claims (4)
1. medical and household small-size ultraviolet air sterilizing apparatus, it is that air filter, centrifugal blower, quartz ultraviolet ray sterilamp and electric control gear are housed in the casing that has return air inlet and air outlet, it is characterized in that quartz ultraviolet ray sterilamp fluorescent tube is mounted in blower fan outlet or the import air channel and is parallel to airflow direction to arrange; Centrifugal blower then adopts the built-in outer rotor motor driven of spiral case.
2. small-sized ultraviolet air sterilizing apparatus according to claim 1, the air channel inwall that it is characterized in that being equipped with the quartz ultraviolet ray sterilamp is a reflector.
3. small-sized ultraviolet air sterilizing apparatus according to claim 1 is characterized in that centrifugal blower fan blade wheel is to be fixed on the outer rotor of motor.
4. according to claim 1,2 or 3 described small-sized ultraviolet air sterilizing apparatus, it is characterized in that having desk-top and two kinds of different outward appearance patterns of console model.
