Description

Novel electron sterilization water dispenser

The utility model belongs to living-hygienic apparatus technical field, and being specifically related to does not a kind ofly need heat temperature raising and tap water is carried out germ-resistant novel electron sterilization water dispenser.

Utilizing type of heating that tap water is carried out germicidal treatment is a kind of usual way, yet it is slow that this thermal treatment method for disinfection has sterilization speed, energy expenditure height, the shortcomings such as physical and chemical index of change water.Thereby the sterilization of present non-heat treated tap water is just obtaining people's attention, people begin one's study and seek new sterilization technology, as technology such as Micvowave Sterilization, ultrasonic sterilization, laser sterilizations, though achievement out of the ordinary is arranged, but or because of use technology requirement harshness, or be difficult to promote, so at present also not really towards this class sterilization water dispenser of consumers in general because of the sterilization cost significantly increases.

At the problem that prior art exists, the utility model has designed a kind of high electric field pulse sterilization that utilizes, and cost is low, the novel electron sterilization water dispenser that eradicative rate is high.

The implementation of present technique is as follows:

Novel electron sterilization water fountain adopts has installed a cover electronic mycocidal device in the water fountain of routine, the electronic mycocidal electrode is installed in the water exit of water fountain.Described electronic mycocidal device provides power supply by the 220V civil power, and controls a pulse generating circuit by controller, and this pulse generating circuit connects high voltage generating circuit, connection electrode again.Described electrode directly contacts with water, and the water-in of water fountain can directly connect tap water, and the water outlet water outlet is capable of direct drinking.

This device is in order to widen the adaptability to mains supply, and power source circuit is selected the parallel connection selfexciting switch voltage-stabilizing circuit for use, and has strengthened its transient error ability, guarantees the stability and the reliability of instrument work; Pulse generating circuit then produces under the control of pilot circuit and helps germ-resistant train of impulses.This train of impulses is delivered to electrode and is formed the sterilization electric field after high voltage generating circuit boosts to the 20-50 kilovolt.

The sterilization mode of this machine utilization is the high-voltage pulse sterilization mode, and it is essentially different with tradition sterilization mechanism, makes these facility be equipped with following outstanding advantage:

1. sterilization speed is fast.During sterilization, liquid flow is through high-voltage electric field, and bacterium just is killed at once under the high-voltage electric field effect.The sterilization of liquids flow reaches 60ML/S-360ML/S.Be fit to multiple occasion under sterilization of liquids.

2. sterilization rate height.To intestinal bacteria, sterilization rates such as Salmonellas reach 100%, and to aspergillus tubigensis, sterilization rates such as yeast are greater than 98%, and once sterilization back liquid can reach standard for drinking.

3. temperature rise heat is little.Actual probe temperature rises less than 0.5-1 degree centigrade during sterilization, also reaches little to the physical and chemical index influence of water.

4. use easy and simple to handlely, water outlet is promptly sterilized.

5. it is low to consume energy.Power consumption also need not be assisted consumable material less than 1 degree/ton, is the minimum and free of contamination state-of-the art sterilising method of present energy consumption.

Below in conjunction with drawings and Examples present technique is described further:

Fig. 1 is this novel electron sterilization water dispenser structural representation;

Fig. 2 is an electronic mycocidal device circuit functional block diagram;

Fig. 3 is the power supply and the controller circuitry figure of electronic mycocidal device;

Fig. 4 is the high voltage generating circuit figure of electronic mycocidal device.

Embodiment: referring to Fig. 1, this water dispenser is by integrating conventional water dispenser electric heating function and the distinctive electronic mycocidal of present technique, the structure of water dispenser can keep conventionally form, top is water tank 1, and tap water is entered by water-in 2, divides two-way, one the tunnel enters electrically heated case 9, carry out heat-sterilization by electric heater unit 7, flow out, realize conventional water dispenser function by boiling water outlet 8.In the water exit 3 on another road electrode 4 is set, controls by electronic mycocidal device 6 circuit.Water purification behind electronic mycocidal is flowed out by pure water inlet 5.

The electronic mycocidal device circuit block diagram of this water dispenser is made up of power supply, controller, pulse generating circuit, high voltage generating circuit and electrode referring to Fig. 2.Its physical circuit is referring to Fig. 3 and Fig. 4: as shown in Figure 3, the 220V AC power is delivered to D1-4 through switch S 301 1, after rectification, obtain about 300V direct current, Q302, Q301 etc. are converted to DC pulse again with it under the control of controller, this DC pulse obtains stable 150V direct current output through the T303 transformation after the D8 rectification.R3023, R3024, RW301, D9 etc. form sampling circuit, and its sampling result is delivered to the working order of controller regulation and control Q301, Q302, make the output all-the-time stable on 150V.Controller also produces suitable sterilization train of impulses simultaneously and opens by 16 pin and export.The button that 12,13,15,17 pin of controller are formed can be adjusted output voltage and train of impulses wave mode.Fig. 4 is a high voltage generating circuit, and it amplifies train of impulses and boost to 20-50KV and delivers to electrode and sterilize.
