Description

Ozone sterilizer for bedclothes

What the present invention relates to is a kind of sterilizing machine that is used for health care and relative article sterilization field, particularly be a kind of hospital ward cotton-wadded quilt disinfectant ozone sterilizer for bedclothes that is used for.

Owing to cross infection control work in the hospital is more and more paid attention to, country several times revises constantly perfect to the disinfection standard of hospital in recent years.With regard to air and body surface, all have new sterilization means to produce frequently, but the article that carry disease germs in a large number such as similar cotton-wadded quilt, medicated pillow, woollen blanket do not have effective sterilization means all the time in the hospital lesion, as the traditional approach ultraviolet radiation, exist penetration power poor, a disinfecting surface; Use sunlight exposure, then be subjected to weather, environmental limit and out-of-date already.For now, still not having a kind of effective device sterilizes completely to above-mentioned article.

In view of above reason, the objective of the invention is in order to provide a kind of penetration strong the ozone sterilizer for bedclothes that Disinfection Effect is good.

The object of the present invention is achieved like this: sterilizing machine of the present invention comprises air filter, the ozonator that is connected with air filter by pipeline, by the disinfecting container that pipeline and inflating pump are connected with ozonator, the air vent of disinfecting container is equipped with exhaust pump (referring to Fig. 1～Fig. 3).

In the above-mentioned sterilizing machine container filled with water is arranged, the two ends of the pipeline that communicates with container filled with water are connected (referring to Fig. 1) with ozonator respectively with disinfecting container, under dry season or dry environment, when making ozone enter disinfecting container, increase the humidity in the disinfecting container, improve sterilization effect.

Above-mentioned ozonator comprises the corrosion resistant airtight casing of insulation, is fixed on the tubular ozone generator in the airtight casing, air inlet, venthole is arranged (referring to Fig. 2～Fig. 3) on the airtight casing.

Termination electrode head in the above-mentioned tubular ozone generator places that closed box is external (referring to Fig. 2～Fig. 4), can stop generator tube two electrodes because of the arcing phenomenon that life-time service produces, to increase the service life.

There are silicone rubber or viton seal ring (referring to Fig. 3) in above-mentioned tubular ozone generator and airtight casing junction, and sealing effectiveness is good.

In the above-mentioned sterilizing machine automatic control circuit is arranged, automatic control circuit comprises power circuit, the chip controls circuit that is connected with power circuit, the control output interface circuit (referring to Fig. 1, Fig. 4) that is connected with the chip controls circuit with power circuit respectively.

Above-mentioned power circuit comprises by capacitor C 10, C11, the civil power anti-jamming circuit that inductance coil L1, L2 form, step-down transformer T1, by D4-D7, C8, the current rectifying and wave filtering circuit that C9 forms, by ic chip 2, capacitor C 5, C6, the three-terminal voltage-stabilizing circuit (referring to Fig. 4) that ic chip 3, capacitor C 6, C7 form.

The electrify restoration circuit of the IC1 that above-mentioned chip controls circuit comprises ic chip 1, be made up of capacitor C 1, resistance R 1,20 feet of C1 one termination IC1 and divide a termination reset switch AN to ground, R1 is connected on (referring to Fig. 4) between C1 and the ground.

Above-mentioned control output interface circuit comprises IC 4, audion BG3, BG4, BG5, BG6 (referring to Fig. 4).

Referring to Fig. 1～Fig. 5, when the present invention works, earlier minute ozone concentration is reached greater than 1000～2000mg/m by ozonator work number ³Restarting exhaust pump bleeds to disinfecting container, after air in the disinfecting container is by basic the eliminating, close exhaust pump and open switch between disinfecting container and the ozonator simultaneously and inflating pump makes ozone be transported in the disinfecting container and is penetrated into fully in cotton-wadded quilt or the sterilizing objects, article in the disinfecting container begin to carry out disinfection under the effect of ozone, when disinfecting container returns to normal barometric pressure, ozone in the container is because of being subjected to physical absorption, organic chemical reaction, the temperature reduction, factors such as biological respinse can make ozone concentration reduce in a large number, need enough ozone concentrations and keep certain disinfecting time and reach the hospital disinfection standard, at this moment inflating pump works on and made the ozone amount in the container obtain further replenishing in several minutes, through the airtight fumigation of 30～60 minutes ozone, sterilizing objects such as cotton-wadded quilt surface and inner natural bacteria can descend 70～90%.

The present invention has following advantage:

1, penetration is strong, and it is thorough, effective to sterilize;

2, ozone does not have residual hazard, non-secondary pollution;

3, easy and simple to handle, safety, whole process is once finished, and can manually also can carry out fully automatic sterilizing.
