Specific embodiments

[0027] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Now, in combination with the drawings, the preferred embodiments of the present invention will be described in detail.

[0028] Refer to Figures 1 to 5 As shown, it shows an embodiment of the discharge device and the sterilization device of the present invention. The discharge device includes a first voltage component 1 and a second voltage component 2. The voltage of the first voltage component 1 is greater than the voltage of the second voltage component 2. A spacing channel 3 is provided between the first voltage component 1 and the second voltage component 2. The first voltage component 1 is provided with a plurality of air inlet holes 11 penetrating both sides thereof, and the second voltage component 2 is provided with a plurality of air outlet holes 23 penetrating both sides thereof; wherein, air enters the spacing channel 3 from one side of the first voltage component 1 through the air inlet holes 11, is ionized and then flows out through the air outlet holes 23.

[0029] Specifically, in a confined space, due to scenarios with a narrow space, poor ventilation, and a complex environment, as the enclosure time extends, a series of problems such as aerosol pollution, microbial reproduction, and the growth of various odors occur, seriously threatening human respiratory health. The discharge device of the present application is used in such a scenario. The discharge device is used to break down the air medium under high voltage, thereby ionizing neutral gas into gas-phase active particles containing O3, NO2, NO, etc. with strong oxidizing properties to achieve the effect of inhibiting and killing bacteria in the space.

[0030] The discharge device includes a first voltage component 1 and a second voltage component 2. The voltage of the first voltage component 1 is greater than that of the second voltage component 2. The first voltage component 1 and the second voltage component 2 are used to cooperate together to form a discharge structure for ionizing air. The first voltage component 1 and the second voltage component 2 are arranged at intervals, so that there is an interval channel 3 between the first voltage component 1 and the second voltage component 2, that is, there is a spacing between the first voltage component 1 and the second voltage component 2. The first voltage component 1 and the second voltage component 2 are respectively connected to a power supply. After being powered on, an electric field is formed in the interval channel 3, and the electric field is used to ionize air to form gas-phase active particles and free radicals. A plurality of air inlet holes 11 are provided on the first voltage component 1. The plurality of air inlet holes 11 are arranged at intervals. The air inlet holes 11 penetrate both sides of the first voltage component 1, and the air inlet holes 11 communicate the interval channel 3 and the side of the first voltage component 1 away from the second voltage component 2. The air inlet holes 11 are used to guide air into the interval channel 3 for ionization to occur in the interval channel 3.

[0031] The second voltage component 2 is provided with a plurality of air outlet holes 23. The air outlet holes 23 penetrate both sides of the second voltage component 2, and the air outlet holes 23 communicate the interval channel 3 and the side of the second voltage component 2 away from the first voltage component 1. The air outlet holes 23 are used to guide the ionized gas-phase active particles and free radicals to the outside of the discharge device.

[0032] Among them, when starting the discharge device, both the first voltage component 1 and the second voltage component 2 are energized, and an electric field is formed in the interval channel 3. Air enters the interval channel 3 from the side of the first voltage component 1 away from the second voltage component 2 through the air inlet hole 11, and is ionized into gas-phase active particles and free radicals with strong oxidizing properties such as in the electric field. The gas-phase active particles and free radicals generated after ionization flow through the air outlet hole 23 to the side of the second voltage component 2 away from the first voltage component 1, that is, the gas-phase active particles and free radicals are flowed into the external space. The gas-phase active particles can react with lipids and proteins in the microbial cell membrane, destroying its integrity and causing the leakage of cell contents (such as proteins, DNA); the gas-phase active particles can also bind to enzymes (such as dehydrogenase, ATPase) in the microorganism, making them inactivated and blocking energy metabolism and material synthesis; the free radicals can attack the nucleic acid chain, resulting in DNA double-strand breakage or base damage, making the microorganism lose its replication ability, and finally realizing the antibacterial and bactericidal effect on air.

[0033] Therefore, through the discharge device of the present application, air is ionized in the interval channel 3 between the first voltage component 1 and the second voltage component 2 to form gas-phase active particles and free radicals with strong oxidizing properties. The gas-phase active particles and free radicals can destroy the cell membrane, enzyme system and genetic material of microorganisms, thereby realizing the efficient disinfection and killing of microorganisms (such as bacteria, viruses, fungi, etc.) in the space, so as to achieve a strong antibacterial and bactericidal effect; at the same time, during the process of the discharge device ionizing air and during the reaction process of the gas-phase active particles and free radicals, no toxic substances harmful to the human body are generated, realizing a green and harmless sterilization effect, realizing the coexistence of humans and machines, and the discharge device has a small volume and strong applicability, and can achieve the antibacterial and bactericidal effect in a small space.

[0034] More specifically, the discharge form of the discharge device belongs to dielectric barrier discharge, and both the first voltage component 1 and the second voltage component 2 are driven by an alternating voltage, and the voltage range is 6 - 9 KV.

Specifically, the first voltage component 1 is used to introduce a high-voltage current and form an electric field with the second voltage component 2 in the interval channel 3. The first voltage component 1 includes a high-voltage insulating layer 12 and a high-voltage electrode 13. The high-voltage insulating layer 12 is used for insulation, avoiding the occurrence of conductive phenomena on the outside of the first voltage component 1, affecting the normal operation of the first voltage component 1 and avoiding potential safety hazards.

[0036] The high-voltage electrode 13 is fixedly arranged inside the high-voltage insulating layer 12. The high-voltage electrode 13 is electrically connected to a power supply, so that the high-voltage electrode 13 has a conductive function. At the same time, both the high-voltage insulating layer 12 and the high-voltage electrode 13 are penetrated by the air inlet hole 11, that is, the air inlet hole 11 penetrates through the high-voltage electrode 13 and the high-voltage insulating layer 12 respectively, so that air can flow through the high-voltage insulating layer 12 and the high-voltage electrode 13 from one side of the first voltage component 1 through the air inlet hole 11 and enter the spacer channel 3, ensuring the flow direction of the air and its ionization.

[0037] Among them, when the power supply is turned on, a current flows through the high-voltage electrode 13, so as to form an electric field with the second voltage component 2 to realize the ionization of air. The high-voltage electrode 13 is arranged inside the high-voltage insulating layer 12, which can protect the high-voltage electrode 13, avoid the risk of electric leakage of the first voltage component 1, improve the service life of the high-voltage electrode 13, and improve the structural stability of the first voltage component 1.

[0039] More specifically, the overall shapes of the first voltage component 1 and the second voltage component 2 are not limited to circular or square. The air inlet holes 11 and the air outlet holes 23 are evenly distributed on the first voltage component 1 and the second voltage component 2 respectively. The aperture ranges of the air inlet holes 11 and the air outlet holes 23 are 1-3 mm.

[0040] In a specific embodiment, referring to Figure 4 As shown, the high-voltage insulating layer 12 includes a first insulating layer 121 and a second insulating layer 122 which are fixedly connected.

Specifically, the high-voltage insulating layer 12 includes a first insulating layer 121 and a second insulating layer 122. The first insulating layer 121 and the second insulating layer 122 are fixedly connected, and both the first insulating layer 121 and the second insulating layer 122 have insulating effects.

[0041] The first insulating layer 121 and the second insulating layer are respectively located on both sides of the high-voltage electrode 13, that is, the high-voltage electrode 13 is fixedly arranged between the first insulating layer 121 and the second insulating layer 122. The first insulating layer 121, the second insulating layer 122 and the high-voltage electrode 13 have the same shape and structure, so as to ensure the structural stability of the first voltage component 1. The first insulating layer 121 and the second insulating layer 122 provide comprehensive insulation for the high-voltage electrode 13 to ensure the normal operation of the first voltage component 1 and reduce potential safety hazards.

[0042] More specifically, the first insulating layer 121, the high-voltage electrode 13 and the second insulating layer 122 are arranged in sequence and integrally formed by pressing to improve the structural stability of the first voltage component 1 and extend the service life of the first voltage component 1.

[0043] In a specific embodiment, referring to Figure 3 As shown, there is a first distance between the edge of the air inlet hole 11 and the high-voltage electrode 13, and the first distance is 1-2.5 mm. Specifically, the air inlet hole 11 penetrates through the high-voltage insulating layer 12 and the high-voltage electrode 13. The air inlet hole 11 and the high-voltage electrode 13 are arranged at intervals, that is, there is a certain distance between the high-voltage electrode 13 and the outer edge of the air inlet hole 11. The high-voltage electrode 13 is arranged around the outside of the air inlet hole 11 at intervals. There is a first distance between the high-voltage electrode 13 and the edge of the air inlet hole 11, and the first distance is set to 1-2.5 mm. The specific value can be selected according to the area of the first voltage component 1, so that when the first voltage component 1 discharges at high voltage, a safety distance is provided between the high-voltage insulating layer 12 and the high-voltage electrode 13 to prevent creepage and improve safety.

[0044] In an embodiment, referring to Figure 2 and Figure 4 As shown, the second voltage component 2 includes a low-voltage insulating layer 21 and a low-voltage electrode 22.

Specifically, the second voltage component 2 is used to introduce a low-voltage current and form an electric field with the first voltage component 1 in the interval channel 3. The second voltage component 2 includes a low-voltage insulating layer 21 and a low-voltage electrode 22. The low-voltage insulating layer 21 is used for insulation to prevent conduction on the outside of the second voltage component 2, which affects the normal operation of the second voltage component 2 and avoids potential safety hazards.

[0045] The low-voltage electrode 22 is fixedly arranged inside the low-voltage insulating layer 21. The low-voltage electrode 22 is electrically connected to a power source, so that the low-voltage electrode 22 has a conductive function. At the same time, both the low-voltage insulating layer 21 and the low-voltage electrode 22 are penetrated by the air outlet holes 23, that is, the air outlet holes 23 penetrate through the low-voltage electrode 22 and the low-voltage insulating layer 21 respectively, so that the gas-phase active particles and free radicals generated after ionization can flow through the low-voltage insulating layer 21 and the low-voltage electrode 22 from the side of the second voltage component 2 close to the spacer channel 3 through the air outlet holes 23 to the outside space, so as to ensure the flow direction of the gas-phase active particles and free radicals generated after ionization.

[0046] Wherein, when the power source is turned on, a current flows through the low-voltage electrode 22, so as to form an electric field with the first voltage component 1 to realize the ionization effect on air. The low-voltage electrode 22 is arranged inside the low-voltage insulating layer 21, which can protect the low-voltage electrode 22, avoid the risk of electric leakage of the second voltage component 2, improve the service life of the low-voltage electrode 22, and improve the structural stability of the second voltage component 2.

[0047] More specifically, the insulating material of the low-voltage insulating layer 21 can be selected from PCB, PTFE, ceramics, etc., and the material of the low-voltage electrode 22 can be selected from easily conductive metals such as copper foil and aluminum foil.

[0048] In a specific embodiment, referring to Figure 4 As shown, the low-voltage insulating layer 21 includes a third insulating layer 211 and a fourth insulating layer 212 fixedly connected, and the third insulating layer 211 and the fourth insulating layer 212 are respectively located on both sides of the low-voltage electrode 22. Specifically, the low-voltage insulating layer 21 includes a third insulating layer 211 and a fourth insulating layer 212, the third insulating layer 211 and the fourth insulating layer 212 are fixedly connected, and both the third insulating layer 211 and the fourth insulating layer 212 have an insulating effect.

[0049] The third insulating layer 211 and the fourth insulating layer are respectively located on both sides of the low-voltage electrode 22, that is, the low-voltage electrode 22 is fixedly arranged between the third insulating layer 211 and the fourth insulating layer 212. The third insulating layer 211, the fourth insulating layer 212 and the low-voltage electrode 22 have the same shape and structure, so as to ensure the structural stability of the second voltage component 2. The third insulating layer 211 and the fourth insulating layer 212 provide a comprehensive insulating effect on the low-voltage electrode 22 to ensure the normal operation of the second voltage component 2 and reduce potential safety hazards.

[0050] More specifically, the third insulating layer 211, the low-voltage electrode 22, and the fourth insulating layer 212 are arranged in sequence and integrally pressed and formed to improve the structural stability of the second voltage component 2 and extend the service life of the second voltage component 2.

[0051] More specifically, compared with a three-insulating-layer two-electrode integrated dielectric barrier module (with the same dielectric layer thickness and the same number of holes), the first voltage component 1 and the second voltage component 2 can significantly reduce the operating voltage, and the specific value is reduced from 18 kV to 6 kV.

[0052] In one embodiment, referring to Figures 1 to 3 As shown, there is a second spacing between the edge of the air outlet hole 23 and the low-voltage electrode 22, and the second spacing is 1 - 2.5 mm. Specifically, the air outlet hole 23 penetrates through the low-voltage insulating layer 21 and the low-voltage electrode 22, and the air outlet hole 23 is arranged at an interval from the low-voltage electrode 22, that is, there is a certain distance between the low-voltage electrode 22 and the outer edge of the air outlet hole 23.

[0053] In one embodiment, referring to Figure 4 and Figure 5 As shown, the thickness of the spacing channel 3 is 1 - 2 mm. Specifically, the ionization of air occurs in the spacing channel 3 between the first voltage component 1 and the second voltage component 2. By adjusting the thickness of the spacing channel 3, the corona inception voltage and the stable operating voltage of the dielectric barrier discharge can be reduced. Among them, the smaller the thickness of the spacing channel 3, the relatively lower the excitation voltage required for the discharge device. To ensure the normal operation of the discharge device, in this embodiment, the thickness of the spacing channel 3 is set to 1 - 2 mm, that is, the spacing between the first voltage component 1 and the second voltage component 2 is 1 - 2 mm, so that air can be stably ionized into gas-phase active particles and free radicals in the spacing channel 3, and at the same time, the stable operating voltage is controlled within 6 - 9 kV to ensure the stable operation of the discharge device.

[0054] In a specific embodiment, referring to Figures 1 to 3As shown, the multiple intake holes 11 are arranged at intervals, and the edge distance between two adjacent intake holes 11 is 1-4 mm; and / or, the multiple outlet holes 23 are arranged at intervals, and the edge distance between two adjacent outlet holes 23 is 1-4 mm. Specifically, the multiple intake holes 11 are arranged at intervals and evenly on the first voltage member 1, so that air can efficiently enter the interval channel 3 from the multiple intake holes 11 and be efficiently ionized. In this embodiment, the edge distance between two adjacent intake holes 11 is set to 1-4 mm, that is, the distance between the outer edges of two adjacent intake holes 11 is 1-4 mm, so as to ensure that as many intake holes 11 as possible are arranged on the first voltage member 1, improve the air intake efficiency of the discharge device, and then improve the bactericidal and antibacterial efficiency, and ensure the structural strength of the first voltage member 1 and improve the service life of the first voltage member 1.

[0055] And / or, the multiple outlet holes 23 are arranged at intervals and evenly on the second voltage member 2, so that the gas-phase active particles and free radicals generated after ionization flow from the interval channel 3 to the external space through the multiple outlet holes 23 to sterilize and inhibit bacteria on the microorganisms in the external space. In this embodiment, the edge distance between two adjacent outlet holes 23 is set to 1-4 mm, that is, the distance between the outer edges of two adjacent outlet holes 23 is 1-4 mm, so as to ensure that as many outlet holes 23 as possible are arranged on the second voltage member 2, improve the air outlet efficiency of the discharge device, and then improve the bactericidal and antibacterial efficiency, and ensure the structural strength of the second voltage member 2 and improve the service life of the second voltage member 2.

[0056] This embodiment also provides a sterilization device (not shown in the figure). The sterilization device includes a discharge device, and the discharge device can adopt any one of the discharge devices provided by the present invention. Since the specific structure and working principle of the discharge device have been introduced in detail in the previous description, for the sake of simplicity of the description, it will not be repeated here.

[0057] In the sterilization device of this embodiment, because the discharge device provided by the present invention is adopted, the discharge device can achieve a strong bactericidal and antibacterial effect and is green and harmless. Therefore, the sterilization device can achieve coexistence of humans and machines, that is, the sterilization device can be set in a space where people are active, thereby improving the applicability of the sterilization device, as well as the sterilization effect and sterilization efficiency of the sterilization device.

[0058] In one embodiment, the sterilization device further includes an atomization device (not shown in the figure), and the atomization device is disposed above the discharge device and is used to spray water mist toward the discharge device. Specifically, the sterilization device further includes an atomization device, the atomization device is disposed above the discharge device, and the atomization device is used to spray water mist toward the discharge device so that the water mist can wrap the gas-phase active particles generated after ionization, thereby generating a variety of reactive oxygen species (ROS) and reactive nitrogen species (RNS), such as long-lived particles such as O3, H2O2, NO2-, NO3-, etc. and short-lived particles such as O, OH, NO, etc. Then, the gas-liquid mixture of the gas-phase active particles wrapped by the water mist is released to the outside of the sterilization device, so that the gas-liquid mixture can achieve the effects of uniform sterilization, bacteriostasis, and dead-angle-free disinfection in the space.

[0059] Among them, when the sterilization device is started, the first voltage component 1 and the second voltage component 2 are both powered on, and an electric field is formed in the interval channel 3. Air enters the interval channel 3 from the side of the first voltage component 1 away from the second voltage component 2 through the air inlet hole 11, and is ionized into gas-phase active particles and free radicals with strong oxidizing properties under the action of the electric field; at the same time, the atomization device sprays water mist toward the position of the discharge device, and the water mist enters the interval channel 3 from top to bottom through the air inlet hole 11, wraps the gas-phase active particles in the interval channel 3 to form a gas-liquid mixture, and then the gas-liquid mixture is released to the outside of the sterilization device through the air outlet hole 23. The gas-liquid mixture reacts with lipids and proteins in the microbial cell membrane in the external space, destroys its integrity, and causes the leakage of cell contents (such as proteins, DNA); the gas-phase active particles can also bind to enzymes (such as dehydrogenase, ATPase) in the microorganism, inactivate them, block energy metabolism and substance synthesis, and finally achieve the effect of sterilization and bacteriostasis.

[0060] Therefore, in the sterilization device of this embodiment, the discharge device and the atomization device cooperate with each other. The water mist sprayed by the atomization device can wrap the gas-phase active particles generated by the ionization of the discharge device to form a gas-liquid mixture, so as to improve the service life of the gas-phase active particles, and the gas-phase active particles can move with the water mist, expanding the sterilization range, and cold plasma and active substances can be uniformly generated in a small space, achieving the effect of bacteriostasis and sterilization in a small space, thereby improving the sterilization effect and sterilization intensity of the sterilization device.

[0061] More specifically, the driving voltage of the atomization device is 16 - 18V, and the atomization rate is controlled at 57.4 - 103.32 g / h. Under these electrical parameters, the evaporation amount of the water mist on the surface of the discharge device can balance the heat generated on the surface of the discharge device, ensure that the surface of the discharge device is dry, and avoid abnormal situations such as water droplet condensation and water accumulation.
