Abstract
The utility model relates to an automatic control device which is used when an ultraviolet sterilizing lamp carries out sterilization to local space areas and irradiated surfaces of objects in industries of medical treatment, sanitation, biochemical medical preparation, etc. The utility model is composed of a power supply, an oscillating unit (a clock), a cycle counting unit (a timing unit), a resetting unit, a driving unit, etc. The utility model has the advantage that when an ultraviolet sterilizing lamp controlled by the utility model is used for sterilization, the utility model can realize the timing automatic start and the timing stop of the ultraviolet lamp for two times a day according to the requirements of 'sterilizing technical specification and standard '. As a result, the ultraviolet disinfecting and sterilizing effect is guaranteed, the possibility that workers are damaged by ultraviolet rays without meaning, and simultaneously, the human power is saved.
Description
The utility model is the special designed a kind of automatic control equipment of uviol lamp for using ultraviolet sterilization lamp that the air and the object exposure surface in certain local space zone carried out disinfection and sterilize in the industries such as medical treatment, health, biochemical pharmacy.
At present, when using ultraviolet sterilization lamp (hereinafter to be referred as sterilamp) to carry out ultraviolet irradiation sterilization (hereinafter to be referred as sterilization), most units are fixedly mounted on indoor certain position with sterilamp, and all do not have timing control apparatus.During sterilization, at first the staff leaves the workplace that is sterilized, and connects the sterilamp power supply again.Closed sterilamp by staff on duty more later in 30 minutes.If this workplace is that (being meant might be by the area of patient's indirect pollution in the Semi-Contaminated Zone, comprise between the buffering of ward, inside corridor, Staff Office, therapeutic room and allly worn the auxiliary room that white frock is come in and gone out by doctor's anti-personnel) time, then such zone must be carried out twice above disinfect (referring to the 81st page of " disinfection technology standard and standard " (first volume)) every day at least and just needed the special messenger in this class department like this and went to work preceding 1 hour and After Hours to this working region disinfection in every day.Adopt the weak point of manual operation to be; 1. no matter carrying out several times to certain zone every day, sterilizing operation must have the special messenger to be responsible for.2. the staff might be subjected to the damage of sterilamp when closing sterilamp.3. when if every day must be carried out the above sterilization of twice or twice in this working region, disinfection might can not get guaranteeing that long-term so its hidden danger may be bigger.
The purpose of the utility model design just is that when using the sterilamp of the utility model control to carry out disinfection to certain local space zone at any time, as long as connect the power supply of sterilamp, sterilamp is closed in this sterilamp sterilization beginning timing simultaneously automatically after 45 minutes.Particularly when this zone must carry out sterilizing more than twice every day, it can be controlled sterilamp and starts sterilamp once more automatically and sterilamp work is closed after 45 minutes voluntarily when playing 12 hours when once opening the sterilamp power supply last, is implemented in the work that carries out disinfection automatically under the unwatched situation.

As the above analysis, when the ultraviolet sterilization lamp that uses the utility model control carries out disinfection, as long as the user connects the power supply of ultraviolet sterilization lamp, ultraviolet disinfection begins, automatically close uviol lamp after 45 minutes, sterilization for the first time finishes, and starts ultraviolet sterilization lamp after after this 11 hours 15 minutes again for the second time environment is carried out the sterilization second time ...For example; Open at 5 o'clock in afternoon one day behind the sterilamp to 5: 45 timesharing, sterilization for the first time finishes, 5 o'clock the next mornings the utility model start sterilamp once more and this environment is carried out second time sterilize ...Powered-down at any time when the user does not need to sterilize stops work of the present utility model.
The utlity model has following advantage; One, regularly 45 minutes automatically after starting Close sterilamp. Can again start also voluntarily when two, starting rear 12 hours for the first time Regularly closed sterilamp in 45 minutes. Three, when not carrying out disinfection, can arbitrarily interrupt certainly Start building to do (closing the ultraviolet sterilization power switch) state. It is reliable to have disinfecting time, Control easy saving manpower and eliminated ultraviolet ray to the meaningless infringement of staff Meaning.
