The plasma sterilization device 400 is used for exciting plasma under the condition of power-on and providing raw materials for indoor air purification operation. In one embodiment, the power supply 420 may be a rechargeable battery. Specifically, when the power supply 420 has sufficient electric quantity or is electrically connected to an external power supply, the power supply 420 applies voltage to two ends of the low-temperature plasma module 410, so that the high-voltage plate and the low-voltage plate of the low-temperature plasma module 410 discharge respectively, an electric field is formed between the high-voltage plate and the low-voltage plate, and reaction gas arranged between the two plates is ionized, so that ionized gas-like substances composed of positive and negative ions are generated, the stability of the ionized gas-like substances is poor, the positive and negative ions are easily neutralized, electric current is generated and great energy is released, the electric current is easily introduced into viruses and bacteria, and the viruses and the bacteria are denatured and inactivated, so that the purpose of killing the viruses and the bacteria is achieved. In addition, the released energy can also promote the decomposition reaction of the indoor volatile organic compounds to generate carbon dioxide and other small molecular substances, thereby reducing the content of the indoor volatile organic compounds. It should be noted that the low-temperature plasma module 410 of the present embodiment may be any commercially available low-temperature plasma reactor, and the structure is not limited to that shown in the drawings, and the low-temperature plasma reactor may also have other shapes according to different processing technologies, and will not be described herein again.
The air collecting device 500 is used for collecting air at the interrogation site so as to perform centralized purification treatment on the air. In one embodiment, the deformable tube 510 is a support-free universal bamboo joint tube, and can be bent or twisted at will while supporting the gas-collecting hood 520, so as to adjust the orientation and the horizontal height of the input end of the gas-collecting hood 520 and the distance between the input end and the interrogation site, so that the air at the interrogation site can be absorbed by the gas-collecting hood 520 to the maximum extent, thereby improving the applicability and reliability of the air sterilizer 10 and further improving the indoor air purification efficiency. In one embodiment, the gas-collecting hood 520 has a trumpet-shaped structure. By arranging the gas collecting channel 520 in a trumpet-shaped structure, the air inlet area of the gas collecting channel 520 is increased, and the resistance of the inner surface of the gas collecting channel 520 to the air flow is reduced, so that the air inlet amount in the housing 100 is increased, and the air to be purified can be rapidly introduced into the purifying chamber 110.
It should be noted that, in the actual production, the air sterilizer 10 may be made into a sterilizer with a smaller size so as to be placed on the table of an office or hung on a wall, and of course, the size of the air sterilizer 10 may be increased and attached to a dental chair so as to absorb tooth dust generated in the dental operation and gas exhaled from the oral cavity of the patient during the dental operation, thereby avoiding the threat that the gas exhaled from the patient may cause to the medical staff and improving the reliability of the dental operation. In addition, the air sterilizer 10 may be attached to a plurality of apparatuses for oral treatment and interrogation, and the size of the air sterilizer may be adjusted to be suitable for the medical apparatuses, so as to improve the safety of treatment and interrogation, which will not be described herein.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
