The plasma sterilization mechanism can be applied to not only an air purifier but also other equipment requiring air purification, and is not limited. The plasma sterilization mechanism mainly performs sterilization treatment by generating a strong plasma electric field. In the mechanism, a certain electric field is formed between the negative electrode plate 3 and the positive electrode needle 2, and a plasma electric field is generated by the action of the electric field. The plasma electric field can effectively destroy microbial cell membranes and DNA, thereby realizing sterilization effect and ionization decomposition of pollutants such as dust. In order to more clearly and accurately understand the structure and the working principle of the plasma sterilization mechanism, the following details are described:
referring to fig. 1 to 4, a plasma sterilization mechanism includes:
a sterilization case 1;
the positive electrode needle 2 is positively charged and arranged on the sterilization shell 1;
the negative electrode plate 3 is negatively charged and arranged on the sterilization shell 1, the negative electrode plate 3 and the positive electrode needle 2 are oppositely arranged, the negative electrode plate 3 is provided with an electric field hole 31, the projection of the positive electrode needle 2 is positioned in the projection of the electric field hole 31 along the direction of the positive electrode needle 2 towards the negative electrode plate 3;
wherein the electric field hole 31 has a rounded polygonal shape.
The technical scheme that this application provided is mainly through utilizing positive pole needle 2 and negative plate 3 to form the plasma electric field, then utilizes the plasma electric field to ionize the air to reach the effect of purification sterilization, and be the polygon shape of fillet through adopting electric field hole 31, can effectively strengthen the energy intensity of plasma electric field. Specifically, the electric field hole 31 is formed in the negative electrode plate 3, the positive electrode needle 2 is disposed at the electric field hole 31, when the positive electrode needle 2 and the negative electrode plate 3 are conducted, a plasma electric field can be formed at the electric field hole 31, and the electric field hole 31 is also used for air circulation, that is, air can pass through the plasma electric field in the flowing process, so that the air is ionized, and the sterilization and purification effects are achieved. In addition, compared with the square hole in the prior art, the electric field hole 31 with the rounded polygonal shape in the application can more effectively concentrate the electric field in the plasma electric field generating process, so that the electric field distribution is more uniform, and the strength of the plasma electric field is increased. Therefore, the holes with radian can generate stronger plasma electric field, thereby realizing better sterilization effect. In addition, the holes with radian can also reduce the electric leakage and escape of the plasma electric field, so that the plasma electric field is more stable and durable.
The rounded polygon refers to a polygon having rounded corners. It is a graph formed by connecting a plurality of line segments and circular arcs, and each corner is a round angle. And, to the positive electrode needle 2 and negative electrode plate 3, its electric energy supply comes from the power in the outer casing, the positive electrode needle 2 is conducted with the positive electrode of the power, the negative electrode plate 3 is conducted with the negative electrode of the power.
In some embodiments, referring to fig. 2 and fig. 3, the electric field holes 31 are provided in a plurality of array arrangements, and the plurality of electric field holes 31 may be specifically rectangular array arrangements, circular array arrangements, triangular array arrangements, etc., and the specific array arrangements are not limited. Preferably, in this embodiment, the number of the electric field holes 31 is four, and the four electric field holes 31 are arranged in a matrix array, so that the electric field holes 31 are simpler to open, the arrangement is simpler, and the precision is easier to ensure. The plurality of electric field holes 31 arranged in an array is advantageous in making the electric field distribution more uniform. The positive electrode needles 2 are arranged in a plurality, and the positive electrode needles 2 are arranged in an array. The array arrangement of the positive electrode needles 2 is the same as that of the electric field holes 31, so that one positive electrode needle 2 and one electric field hole 31 corresponding to one position form a plasma electric field, and the plasma electric field is uniformly distributed.
Specifically, as for the shape of the electric field hole 31, it may be a rounded square, a rounded pentagon, a rounded hexagon, a rounded octagon, or the like, and in this embodiment, it is preferable that the electric field hole 31 be a rounded regular octagon. By setting the electric field hole 31 to be round-corner regular octagon, compared with the round hole or square hole in the prior art, the plasma electric field with higher intensity can be generated, and the ionization sterilization effect is better. Specifically, the shape with more corners can generate a stronger electric field at the same aperture area, so that the rounded polygonal hole can more effectively concentrate the electric field and thus generate a stronger plasma field, because of having more corners than the circular hole. And compared with square holes, the round-corner polygonal holes can reduce edge effect, and are more uniform in electric field distribution, so that the plasma electric field is more stable.
In some embodiments, referring to fig. 5 and 6, the negative electrode plate 3 is provided with two, specifically, a first negative electrode plate 3 and a second negative electrode plate 3. Wherein, the first negative plate 3 is located one side of sterilization casing 1, and the opposite side of sterilization casing 1 is located to the second negative plate 3, and first negative plate 3 is relative setting with second negative plate 3. The positive electrode needle 2 is arranged between the first negative electrode plate 3 and the second negative electrode plate 3, and two ends of the positive electrode needle 2 are respectively close to electric field holes 31 on the two negative electrode plates 3. 31 when the positive electrode needle 2, the first negative electrode plate 3 and the second negative electrode plate 3 are electrically conducted, the positive electrode needle 2 is close to one end of the first negative electrode plate 3, and forms a plasma electric field with the first negative electrode plate 3; the positive electrode needle 2 is adjacent to one end of the second negative electrode plate 3, and forms a plasma electric field with the second negative electrode plate 3. Therefore, the two negative plates 3 are matched with the same positive needle 2, so that a double plasma electric field can be formed, the structure of the plasma sterilization mechanism is more compact, the sterilization efficiency and strength are increased, and the sterilization is more thorough.
In some embodiments, referring to fig. 4, sterilization housing 1 includes a main body portion 11 and a beam portion 12. The beam portion 12 is connected to one side of the main body portion 11, the positive electrode needle 2 is provided on the beam portion 12, and the negative electrode plate 3 is provided on one side of the main body portion 11 facing away from the beam portion 12. Specifically, the positive electrode pin 2 is inserted into the beam portion 12, and extends to the outside of the beam portion 12 through the thickness of the beam portion 12, so that one end of the positive electrode pin 2 is positioned above the corresponding electric field hole 31 or within the electric field hole 31 to form a plasma electric field.
In some embodiments, sterilization housing 1 forms a plasma sterilization group with positive needle 2 and negative plate 3. In this embodiment, two plasma sterilization groups are provided, and the two plasma sterilization groups are arranged in mirror symmetry to form a dual plasma electric field.
