[0033] See also Figure 1-Figure 4 .
[0034] Some embodiments of the present application disclose a sterilization device of an air disinfector, comprising a housing 1, a plasma generator 2 and an ozone catalyst 3, wherein the plasma generator 2 and the ozone catalyst 3 are installed in the housing 1.
[0035] Among them, the plasma generator 2 is used to sterilize the air, and the excess negative ions generated float in the air to eliminate smoke, dust and odor;
[0036] The ozone catalyst 3 is used to decompose the ozone generated by the plasma generator 2 to reduce the amount of ozone discharged into the air.
[0037] The sterilization device of the air disinfector disclosed in the present application processes the air through a combination of a plasma generator 2 and an ozone catalyst 3 to reduce viruses and bacteria in the indoor air and improve the indoor air quality. Specifically, the plasma generator 2 forms a charged plasma region through a high-voltage electric field, and the oxygen in the air entering the region is ionized to form high-energy oxygen ions and electrons. The oxygen ions and electrons react with water molecules and nitrogen molecules in the air under a high-energy state to generate active oxygen molecules and active nitrogen molecules. The active oxygen molecules and active nitrogen molecules have strong oxidizing and bactericidal properties, and can directly react with microorganisms, bacteria and viruses to destroy their cell structures, oxidize metabolites and nucleic acids, and remove microorganisms, bacteria and viruses in the air; at the same time, the plasma region also produces a certain amount of negative ions and ozone, and the negative ions can adsorb particulate matter and harmful gases in the air, and the ozone also has a strong bactericidal effect, which can further kill bacteria and viruses in the air.
[0038] Due to the active chemical properties of ozone, part of the ozone generated by the plasma generator 2 decomposes by itself, and the other part of the ozone generated by the plasma generator 2 is catalytically decomposed by the ozone catalyst to decompose into oxygen, thereby reducing the ozone emitted into the air. At the same time, the oxygen content discharged into the air from the sterilization device of the air disinfector further improves the air quality and optimizes the purification effect.
[0039] The sterilization device of the air disinfector disclosed in the present application combines a plasma generator with an ozone catalyst, which reduces the ozone discharged into the air while ensuring the purification and disinfection of the air by the plasma generator, so as to avoid the harm caused by excessive ozone concentration.
[0040] The sterilization device of the air disinfector disclosed in the present application can effectively remove bacteria and viruses in the air, and can also remove dust and smoke in the air, thereby effectively improving the indoor air quality.
[0041] The ozone generated by the plasma generator 2 exists not only downstream of the plasma generator 2 but also upstream of the plasma generator 2 in the space enclosed by the casing 1. In the present application, the ozone catalyst 3 can be arranged only upstream of the plasma generator 2, or only downstream of the plasma generator 2, or both upstream and downstream of the plasma generator 2. Preferably, the ozone catalyst 3 is arranged both upstream and downstream of the plasma generator 2. The upstream and downstream are determined according to the flow direction of the air in the sterilization device of the air disinfector.
[0042] The sterilization device of the air disinfector also includes a fan, which is located downstream of the plasma generator 2. When the sterilization device of the air disinfector is working, the fan provides circulation power for the air, and the ozone generated by the plasma generator 2 moves toward the downstream of the plasma generator 2 under the power of the wind, so that the ozone concentration downstream of the plasma generator 2 is higher than the ozone concentration upstream of the plasma generator 2.
[0043] In order to improve the decomposition effect of ozone downstream of the plasma generator 2, in this solution, the number of ozone catalysts 3 arranged downstream of the plasma generator 2 is greater than or equal to the number of ozone catalysts 3 arranged upstream of the plasma generator 2. The ozone located downstream of the plasma generator 2 is decomposed in sequence by multiple ozone catalysts 3 so that the ozone concentration discharged into the air meets the requirements.
[0044] The ozone catalyst 3 located upstream of the plasma generator 2 can not only decompose the ozone generated by the plasma generator 2, but also decompose the ozone in the air circulating into the sterilization device of the air sterilizer.
[0045] At least one ozone catalyst 3 is arranged upstream of the plasma generator 2 , and correspondingly, at least one ozone catalyst 3 is also arranged downstream of the plasma generator 2 .
[0046] In some embodiments of the present application, eight ozone catalysts 3 are arranged on the sterilization device of the air sterilizer, and at least four ozone catalysts 3 are arranged downstream of the sterilization device of the air sterilizer.
[0047] The outer peripheral shape of the plasma generator 2 is the same as that of the ozone catalyst 3, and correspondingly, the inner wall shape of the housing 1 is the same as that of the ozone catalyst 3. Along the air flow direction, the front end face and the rear end face of the housing 1 are both open end faces, and the front end face and the rear end face of the housing 1 are both blocked by the ozone catalyst 3.
[0048] In order to further optimize the above technical solution, the present application provides a first ozone catalyst layer on the inner wall of the housing 1, and the first ozone catalyst layer is used to decompose ozone. In this embodiment, the ozone catalyst 3 cooperates with the first ozone catalyst layer to decompose ozone, which not only improves the ozone decomposition ability, but also can appropriately reduce the number of ozone catalysts 3, thereby reducing the cost of the sterilization device of the air disinfector.
[0049] In this solution, the plasma generator 2 includes multiple groups of electrodes, each group of electrodes includes a high voltage electrode and a ground electrode. The multiple groups of electrodes are cross-crossed and stacked side by side along the flow direction of the air, so that the air can be sterilized and dusted in multiple groups in the plasma generator 2, so as to further improve the sterilization effect of the sterilization device of the air disinfector.
[0050] It should be noted that the multiple groups of electrodes are at least two groups of electrodes. Specifically, the number of electrodes can be two groups, three groups or even more groups.
[0051] Two adjacent groups of electrodes are arranged in a cross-shaped manner and stacked side by side, which can improve the uniformity of the corona field of the plasma generator 2 to a certain extent and improve the sterilization effect on the air. Figure 4 As shown, the electrode includes a positive electrode 21 and a negative electrode 22, and arc discharge is generated by the positive electrode 21 and the negative electrode 22. The negative electrode 22 is formed by a plurality of parallel aluminum sheets, and the positive electrode 21 is a steel wire, which is reciprocally wound in a "J" shape along the length direction of the aluminum sheet, and the arrangement direction of the plurality of "J" shapes is consistent with the direction in which the plurality of aluminum sheets are arranged side by side, and the aluminum sheets of the negative electrodes 22 of two adjacent electrodes are perpendicular to each other, and the winding direction of the steel wires of the positive electrodes 21 of two adjacent electrodes is perpendicular.
[0052] In the embodiment where the plasma generator 2 has two electrodes, the two electrodes are named as the first electrode and the second electrode, respectively. The first electrode includes a first positive electrode and a first negative electrode, and the second electrode includes a second positive electrode and a second negative electrode. The positive electrode 21 and the negative electrode 22 of the two electrodes are arranged as the first negative electrode, the first positive electrode, the second positive electrode and the second negative electrode. The steel wire of the first positive electrode is reciprocatingly wound in a "J" shape along the length direction of the aluminum sheet parallel to the first negative electrode, and the arrangement direction of the multiple "J" shapes is consistent with the direction in which the multiple aluminum sheets are arranged side by side. The steel wire of the second positive electrode is reciprocatingly wound in a "J" shape along the length direction of the aluminum sheet parallel to the second negative electrode, and the arrangement direction of the multiple "J" shapes is consistent with the direction in which the multiple aluminum sheets are arranged side by side. The length direction of the aluminum sheet of the first negative electrode is perpendicular to the length direction of the aluminum sheet of the second negative electrode, and the "J" shape of the first positive electrode is perpendicular to the "J" shape of the second positive electrode. This arrangement can increase the contact area between the plasma generator and the gas, and improve the killing effect on viruses and bacteria in the air.
[0053] In the test of a third party, the sterilization device of the air disinfector disclosed in the present application has a killing rate of 91% for bacteria and viruses in the first hour and 99.7% in the second hour, and the ozone detection is ≤0.078mg / m 3 .
[0054] In some embodiments of the present application, the ozone catalyst 3 includes a honeycomb mesh plate and a second ozone catalyst layer, and the second ozone catalyst layer is arranged on the meshes of the honeycomb mesh plate.
[0055] The ozone catalyst 3 adopts a honeycomb mesh plate, which increases the contact area between the ozone catalyst 3 and the gas and enhances the ozone decomposition capability of the ozone catalyst 3 .
[0056] The meshes of the honeycomb mesh panel are designed according to actual needs and are not specifically limited here.
[0057] Preferably, the meshes of the honeycomb mesh plate of the ozone catalyst 3 located on the same side of the plasma generator 2 are staggered to further increase the contact area between the sterilization device of the air disinfector and the gas, and enhance the ozone decomposition ability of the ozone catalyst 3.
[0058] The honeycomb mesh panel can be a metal mesh panel or a plastic mesh panel.
[0059] The honeycomb mesh plate with an ozone catalyst layer has a strong electrostatic adsorption ability under the action of high pressure, and can adsorb dust or smoke in the air. The present application increases the contact area between the ozone catalyst 3 and the air through the honeycomb mesh plate, thereby enhancing the adsorption effect of the ozone catalyst 3 on dust or smoke.
[0060] The ozone catalyst 3 located upstream of the plasma generator 2 can perform a first adsorption of dust and smoke in the air to reduce the amount of dust and smoke entering the sterilization device of the air disinfector.
[0061] The sterilization device of the air disinfector disclosed in the present application has a large circulating air volume and low noise.
[0062] In some embodiments of the present application, the honeycomb mesh panel is snap-connected to the housing.
[0063] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used, and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. The scope of application involved in the present application is not limited to the technical solution formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned application concept. For example, the above-mentioned features are replaced with the technical features with similar functions disclosed in this application (but not limited to) to form a technical solution.
