Referring to
The positive electrode holder 6 is grid-shaped, and the positive electrode holder 6 is positioned on a top of the insulation enclosure 7 and spaced apart from the air outlet 10 of the metal cylinder-shaped tube 3.
There is an electrode needle 5 suspended directly above an axis center of each metal cylinder-shaped tube 3, with an end of the electrode needle 5 mounted at a skeleton of the positive electrode holder 6, with a spacing (5-10 mm is appropriate) between a tip of the electrode needle 5 and the air inlet 9 of the metal cylinder-shaped tube 3.
with the above configuration, the tip of the electrode needle 5 can be located inside the metal cylinder-shaped tube 3, but still apart from a tube mouth (air inlet 9) with a safe distance, which can achieve an uniform discharge of the tip of the needle, and prevent the generation of ozone, forming an effective corona layer 11 between the needle tip of the electrode needle and walls of the tube, that is: an area from the air inlet 9 to a position 5 mm above the tip of the electrode needle become a corona zone, while the area from the position 5 mm above the tip of the electrode needle to the air outlet 10 is an adsorption area 12.
In specific embodiments, a high-speed rotating corona field 11 is formed between the electrode needle 5 (for example, a discharge alloy needle) and the metal cylinder-shaped tube 3, releasing a large number of positive ions and free radicals to achieve strong mineralized sterilization of the viruses passing through the module, while the large number of positive ions would be enriched on particles and adsorbed by the adsorption zone 12 under Coulomb forces, thus achieving air sterilization in a manned environment.
It should also be noted that the electrode needle 5 must be kept strictly in an axis-center position of the metal cylinder-shaped tube 3, which facilitates controlling the uniform discharge of the needle tip, preventing the ozone generation, and ensuring the corona field effect.
In some embodiments, the apertured negative electrode plate 4 and positive electrode holder 6 are fixedly connected to the insulation enclosure 7 via insulating connecting posts 8, respectively.
In some embodiments, the apertured negative electrode plate 4 is configured parallelly to the positive electrode holder 6.
In some embodiments, the positive electrode holder 6 is spaced more than 10 mm from the cylinder-shaped tube 3 to achieve air insulation.
The insulation enclosure 7 is also provided with an external power connection case 1 and a high voltage pack 2, and the external power connection case 1 is electrically connected with the high voltage pack 2. The high voltage pack 2 has a positive pole electrically connected to the positive electrode holder 6, while the negative pole of the high voltage pack 2 is electrically connected to the apertured negative electrode plate 4. In some embodiments, the high voltage pack has a voltage of 4000v-8000v, and a current is 200 μA-1 mA, with a current limit achieved at 1 mA to ensure the safety of human touch.
In the above embodiments, the cylinder-shaped tube 3 has a height of 1 cm-3.6 cm. The present example creatively focuses on the sterilization ability, weakens the dust removal ability, and strictly controls the height of the cylinder-shaped tube 3 between 1-3.6 cm, so that the overall thickness of the product can be controlled between 2-6 cm, thus achieving an ultra-thin design.
The ultra-thin design of the present disclosure is obtained because that the present disclosure focuses a function on air sterilization ability, and does not require a high adsorption ability. Overly long metal cylinder-shaped tube and electrode needle cannot effectively increase the dust removal ability, but the overly long metal cylinder-shaped tube will easily cause electric field breakdown after dust removal and lead to ozone exceeding, and also increase the difficulty of maintenance. More importantly, an overly long tube length will lead to an increased overall thickness of the equipment, which is not beneficial to usage in practical environment. Moreover, in some key epidemic prevention areas, it is needed to achieve a sterilization rate of 90% at one time, which may require 2 layers of equipment to achieve, so the ultra-thin design becomes particularly important.
Therefore, the ultra-thin design of the present disclosure facilitates the sterilization equipment (the overall thickness of the equipment is as thin as 2.5 cm) being adaptable to air conditioners in any style and has a more aesthetically pleasing appearance, and can be the sterilization equipment with more convenient usage. It can also be designed by a combination of multi-layer of the present design to form a combined equipment with enhanced sterilization ability.
The disclosure has been described by using specific examples above, which are merely for the purpose of facilitating understanding of the disclosure and are not intended to limit the disclosure. For a person of ordinary skill in the art, simple deductions, deformations or changes may be made to the above specific implementations according to the idea of the disclosure.
