Description

The low-temperature plasma bubble generator

The utility model relates to a kind of ozonizer, especially can produce the ozone bubbles that high density has certain pressure again, is fit to do washing machine sterilization, sterilization, deodorizing, raising wash degree, the device that family's water purifies.

At present, ozone generating element and device be old technology mostly still, and the earliest a kind of is to adopt point discharge to produce ozone, and another kind is that the ozone lamp that is referred to as that generally adopts is the glass tubular ozone generator.The service voltage of Glass tubing ozonizer divides two kinds of power frequency and high frequencies, though the ozone amount that the latter is taken place than the former height, circuit complexity cost height.Above-mentioned ozonizer common defective is that volume is big, the life-span is low, power consumption is big, efficient is low; The ozone generating element of above-mentioned form produces certain temperature in discharge process, and ozone is reduced into oxygen O very soon under this temperature ₂, bring certain loss with regard to low producer for again original benefit rate, limited the widespread use of ozone owing to above reason.

The purpose of this utility model provides a kind of low-temperature plasma bubble generator, and it not only overcomes the defective of above-mentioned ozonizer, and can produce high density plasma ozone bubbles at low temperatures, for exploitation ozone type washing machine, water-purification plant provide condition.

The utility model is achieved in that producing the above high-frequency voltage of 3KV through boost-up circuit in producer connects a kind of " radio ceramics creeping discharge low-temperature plasma generation sheet ", this speciogenesis sheet has adopted up-to-date " the radio ceramics creeping discharge generates ozone technology ", this technology changes former point discharge, Glass tubing cylinder discharge generation ozone along dielectric surface discharge generation ozone into, has improved ozone production efficiency significantly.(the structure of low-temperature plasma generation sheet: with ceramic plate as medium, at electrode on the sintering separately on two planes, the electrode of one side is by last insulation layer, the another side electrode is exposed), the core that the radio ceramics creeping discharge generates ozone technology is: pole distance very little (about 0.6mm), contrasted between solid dielectric is pottery or glass etc., when counter electrode applies high-frequency alternating voltage, the magnitude of voltage on the dielectric medium and the electrostatic capacity of electrode are inversely proportional to, ionization of gas when reaching gas breakdown intensity (approximately 3KV/mm) along with the rising of voltage on the electrode, produce the needle-like corona discharge pulse in exposed one side, therefore put aside a large amount of negative ions at dielectric surface, change with air, produce a large amount of ozone and other composition as negative ion.It is low that sheet temperature rise in the continuous discharge process takes place.Volume is the generation sheet of 37 * 15 * 0.6mm, per hour can produce 100mg ozone, quite is 190 times of Glass tubing producer (lamp) generating capacity, and watt consumption very low (being not more than 5W).The ozonizer volume that adopts this principle to produce is very little again.The ozone type washing machine can only adopt this type of efficient ozone generating device to the demand (approximately 30-70ppm) of ozone.Configuration has the air pump of certain pressure in the one-piece construction of the present utility model, will mix the generation ozone water in the entry of ozone with high concentration gas pump with water.

Owing to adopt such scheme to make ozone generator efficiency height, little, the power consumptive province of volume, thereby satisfy the requirement of washing machine, family's water-purification plant.

Below in conjunction with drawings and Examples the utility model is further specified.
