Abstract: A device for deodorization and disinfection is provided. The aforementioned device includes a supporter, a fan module, a high voltage generating module, a controlling circuit, a battery module, and a cover body used to contain aforementioned elements. Aforementioned supporter includes a first supporting portion, a second supporting portion, and a third supporting portion. The fan module attaches to a setting plane of the first supporting portion. The high voltage generating module is configured at the third supporting portion and below the fan module, and a corona generator of the high voltage generating module is configured at an air outlet of the fan module. The battery module is configured at a holding space formed by the second supporting portion and the third supporting portion. The controlling circuit makes the battery module provide power to the fan module and the high voltage generating module.

Abstract: An improved corona generator structure includes a ground tube body sheathed within an insulating sleeve. One end of the ground tube body is provided with a sealing lid for being firmly coupled to the end portion of the ground tube body. At least one piece of high voltage electrode plate is coupled with the insulating sleeve. The high voltage electrode plate is provided with a plurality of spacers for allowing a gap of a substantially equal height to be formed between every area of the high voltage electrode plate and the insulating sleeve so as to uniformly distribute the corona on the high voltage electrode plate when electricity conducts therethrough. Furthermore, the two retaining sleeves are coupled to both end portions of the high voltage electrode plate and the insulating sleeve such that the high voltage electrode plate is firmly positioned on the insulating sleeve.

Abstract: An apparatus to generate corona discharges that consists of (a) a ground electrode tube, (b) a single-opening insulating tube inserted into the ground electrode tube, (c) a high-voltage electrode tube inserted into the insulating tube, and (d) two insulating caps. An air gap is formed between the ground electrode tube and the insulating tube. The high-voltage tube is inserted in the center of the assembly, which is held in position by the insulating caps.
