Description

Technical Field

[0001] This utility model relates to the technical field of air purification, specifically to a sterilization and deodorization device. Background Technology

[0002] Everyday life and industrial production inevitably produce pollutants such as harmful gases, bacteria, and viruses. For example, the stench from places like garbage rooms, toilets, sewage rooms, and factories affects people's production, life, and health.

[0003] Compared to traditional activated carbon adsorption and biological deodorization technologies, plasma sterilization and deodorization technology has advantages such as simple structure, convenient maintenance, and no secondary pollution. Among them, the two more common technologies that generate plasma under normal pressure are corona discharge technology and dielectric barrier discharge technology.

[0004] Corona discharge has a low initiation voltage and a large discharge space, making it easy to implement. However, it has disadvantages such as low discharge power and low electron density.

[0005] Dielectric barrier discharge technology, also known as silent discharge technology, is a non-equilibrium, unstable, and non-uniform discharge technology. Under atmospheric pressure, it is usually a microfilament discharge. Among them, the dual dielectric barrier discharge technology has more stable and uniform discharge, consumes less power, and makes energy easier to utilize effectively.

[0006] Currently, there is a lack of a dual-dielectric barrier discharge technology that can effectively reduce discharge voltage, increase plasma concentration, reduce ozone release, increase sterilization efficiency, and enable sterilization and deodorization devices that allow humans to coexist with the machine.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] Please see Figures 1 to 10According to an embodiment of the present invention, a sterilization and deodorization device is provided. The sterilization and deodorization device includes: a power supply component 1 and a plasma reaction component 2. The power supply component 1 is electrically connected to the plasma reaction component 2 and is used to supply power to the plasma reaction component 2. The plasma reaction component 2 includes: a dielectric barrier 20, a high-voltage electrode 21, and a low-voltage electrode 22. The dielectric barrier 20 is provided with a receiving cavity adapted to the high-voltage electrode 21. The high-voltage electrode 21 is disposed in the receiving cavity. The dielectric barrier 20 and the high-voltage electrode 21 are integrally formed. The power supply terminal of the power supply component 1 is electrically connected to the input terminal of the high-voltage electrode 21 through a first wire passing through the dielectric barrier. The low-voltage electrode 22 is sleeved on the dielectric barrier 20. The side of the low-voltage electrode 22 close to the dielectric barrier 20 is in contact with the dielectric barrier 20. The output terminal of the low-voltage electrode 22 is electrically connected to the ground terminal of the power supply component 1.

[0034] As can be seen, the sterilization and deodorization device provided by this utility model simply sets up a power supply component 1 and a plasma reaction component 2. The plasma reaction component 2 consists of a dielectric barrier 20, a high-voltage electrode 21, and a low-voltage electrode 22. The high-voltage electrode 21 is disposed within a cavity adapted to the dielectric barrier 20, and the dielectric barrier 20 and the high-voltage electrode 21 are integrally formed. The power supply terminal of the power supply component 1 is connected to the input terminal of the high-voltage electrode 21 through a first wire passing through the dielectric barrier, and the output terminal of the low-voltage electrode 22 is electrically connected to the ground terminal of the power supply component 1. It is evident that placing the high-voltage electrode 21 within the cavity of the dielectric barrier 20 can protect the high-voltage electrode 21, and the integral formation of the dielectric barrier 20 and the high-voltage electrode 21 can prevent water vapor or water from entering the cavity through the dielectric barrier 20, thereby improving the service life of the plasma reaction component 2 and reducing maintenance costs. Meanwhile, by integrally molding the dielectric barrier 20 and the high-voltage electrode 21, there is no air between them. Therefore, the plasma reaction component 2 only needs surface drying after cleaning before operation, improving the safety and stability of the equipment. It also improves insulation performance, reduces current leakage and energy loss, and helps maintain the stability of the plasma reaction. This sterilization and deodorization device has the technical advantages of simple and compact structure, low discharge voltage, convenient assembly and maintenance, ultra-low ozone release, high plasma density, high sterilization efficiency, and wide applicability.

[0035] In specific implementation, the dielectric barrier 20 is provided with a connection hole corresponding to at least a portion of the input terminal of the high-voltage electrode 21. The first wire passes through the connection hole and connects to the input terminal of the high-voltage electrode 21. Both sides of the high-voltage electrode 21 are tightly fitted to the dielectric barrier 20, and there is no air between the high-voltage electrode 21 and the dielectric barrier 20.

[0036] In actual operation, the end of the high-voltage electrode 21 closest to the power supply component 1 is the input end of the high-voltage electrode 21. The power supply terminal of the power supply component 1 can be electrically connected to any point of the high-voltage electrode 21 closest to the power supply component 1 through the first wire.

[0037] In actual operation, the power supply terminal of power supply component 1 is connected to one end of the first wire, and the other end of the first wire passes through the connection hole and is connected to the input terminal of high-voltage electrode 21 by soldering. The grounding terminal of power supply component 1 is connected to one end of the second wire, and the other end of the second wire is connected to the output terminal of low-voltage electrode 22. To prevent water from entering through the connection hole, solder is used to seal the connection hole, thereby sealing it.

[0038] In actual operation, the working principle of the plasma reaction component 2 is as follows: the high-voltage electrode 21 and the low-voltage electrode 22 of the plasma reaction component 2 are electrically connected to the power supply terminal and the ground terminal of the power supply component 1, respectively. Thus, the high-voltage electrode 21 and the low-voltage electrode 22 form a circuit through their connection to the power supply terminal and the ground terminal of the power supply component 1, generating an electric field between them. Preferably, the power supply provided by the power supply component 1 is a pulsed AC high-voltage power supply. When the power supply component 1 supplies power to the plasma reaction component 2, the dielectric barrier component 20 achieves dielectric barrier discharge with the high-voltage electrode 21 and the low-voltage electrode 22, generating micro-plasma, thereby achieving the purpose of sterilization and deodorization.

[0039] In this embodiment, as Figures 1 to 5As shown, the sterilization and deodorization device further includes: a limiting component and a fixing component 3. The limiting component is installed on the fixing component 3, and a limiting space is provided inside the limiting component. At least a portion of the plasma reaction component 2 is installed in the limiting space, and the plasma reaction component 2 is connected to the fixing component 3 through the limiting component. The limiting component includes a first limiting component 4 and a second limiting component 5 arranged opposite to each other. The first limiting component 4 and the second limiting component 5 are respectively located on both sides of the plasma reaction component 2, and at least a portion of the first limiting component 4 is detachably connected to at least a portion of the second limiting component 5. The side of the first limiting component 4 near the plasma reaction component 2 is provided with a first limiting groove 40 adapted to the plasma reaction component 2, and the side of the second limiting component 5 near the plasma reaction component 2 is provided with a second limiting groove 50 adapted to the plasma reaction component 2. A limiting space is formed between the first limiting groove 40 and the second limiting groove 50. With this structural arrangement, the plasma reaction component 2 can be fixed and positioned by the first limiting component 4 and the second limiting component 5. Furthermore, the first limiting component 4 and the second limiting component 5 can shield at least a portion of the plasma reaction component 2, thereby preventing it from being damaged by external impacts such as vibration, thus protecting the plasma reaction component 2. Simultaneously, the detachable connection between at least a portion of the first limiting component 4 and at least a portion of the second limiting component 5 facilitates the installation and removal of the plasma reaction component 2 from the first limiting component 4 and the second limiting component 5.

[0040] In the specific implementation process, the first limiting component 4 and the second limiting component 5 are arranged opposite to each other. Both the first limiting component 4 and the second limiting component 5 extend along the height direction of the plasma reaction component 2, and their heights are the same. The first limiting groove 40 extends along the height direction of the plasma reaction component 2, and the second limiting groove 50 extends along the height direction of the plasma reaction component 2. At least two sides of the plasma reaction component 2 are respectively inserted into the first limiting groove 40 and the second limiting groove 50, so as to limit and fix the plasma reaction component 2 by the first limiting component 4 and the second limiting component 5, and to shield at least a portion of the plasma reaction component 2, thereby protecting the plasma reaction component 2.

[0041] In actual operation, the height of the first limiting component 4 and the height of the second limiting component 5 are both higher than the height of the plasma reaction component 2. With this structural arrangement, the first limiting component 4 and the second limiting component 5 can provide a certain degree of shielding and protection for the plasma reaction component 2.

[0042] In actual operation, both the first limiting component 4 and the second limiting component 5 can be made of conductive or insulating materials.

[0043] In the specific implementation process, such as Figures 2 to 5 As shown, the first limiting component 4 includes: a first side plate 41, a first base plate 42, and a first support plate 43. The first side plate 41 is disposed above the first base plate 42. The first side plate 41 is provided with a first slot 410. The length of the first slot 410 extends along the height direction of the plasma reaction component 2. The first base plate 42 is provided with a second slot 420 that communicates with the first slot 410. The length of the second slot 420 extends along the height direction of the plasma reaction component 2. The first support plate 43 is disposed in the second slot 420 and close to the bottom end of the first base plate 42. The length of the first support plate 43 extends along the length direction of the plasma reaction component 2. A first limiting groove 40 is formed between the first slot 410, the second slot 420, and the first support plate 43. The second limiting component 5 includes: a second side plate 51, a second bottom plate 52, and a second support plate 53. The second side plate 51 is disposed above the second bottom plate 52. The second side plate 51 has a third slot 510, the length of which extends along the height direction of the plasma reaction component 2. The second bottom plate 52 has a fourth slot 520 connected to the third slot 510, the length of which extends along the height direction of the plasma reaction component 2. The second support plate 53 is disposed in the fourth slot 520 and close to the bottom end of the second bottom plate 52. The length of the second support plate 53 extends along the length direction of the plasma reaction component 2. A second limiting groove 50 is formed between the third slot 510, the fourth slot 520, and the second support plate 53. The first slot 410 is disposed opposite to the third slot 510, the second slot 420 is disposed opposite to the fourth slot 520, the first support plate 43 is disposed opposite to the second support plate 53, and the first bottom plate 42 is detachably connected to the second bottom plate 52.

[0044] In actual operation, the side wall of the first support plate 43 abuts against the inner wall of the second slot 420, and the side wall of the second support plate 53 abuts against the inner wall of the fourth slot 520. The depths of the second slot 420 and the fourth slot 520 are both half the length of the plasma reaction component 2. The length of the first support plate 43 is less than the depth of the second slot 420, and the length of the second support plate 53 is less than the depth of the fourth slot 520. When the first base plate 42 and the second base plate 52 are connected, mounting holes are formed by the end face of the first support plate 43 near the second support plate 53, the inner wall of the second slot 420, the inner wall of the fourth slot 520, and the end face of the second support plate 53 near the first support plate 43. With this structural arrangement, a first support plate 43 is provided in the second slot 420 and a second support plate 53 is provided in the fourth slot 520 to support and limit the plasma reaction component 2, preventing the plasma reaction component 2 from moving downward. At the same time, mounting holes are provided to facilitate the electrical connection between the power supply component 1 and the plasma reaction component 2.

[0045] In the specific implementation process, such as Figure 3 As shown, a first insertion portion 421 is provided on the side of the first base plate 42 near the second base plate 52, and a second insertion portion 521 adapted to the first insertion portion 421 is provided on the side of the second base plate 52 near the first base plate 42. The first insertion portion 421 and the second insertion portion 521 are inserted and engaged. This structural arrangement allows the first base plate 42 and the second base plate 52 to be positioned and controlled by the first insertion portion 421 and the second insertion portion 521 during connection, thus achieving a better connection and installation. At the same time, the first insertion portion 421 and the second insertion portion 521 ensure a tight connection between the first base plate 42 and the second base plate 52.

[0046] In the specific implementation, the high-voltage electrode 21 is a sheet-like conductive material; the low-voltage electrode 22 is a metal electrode wire, which is evenly wound around the dielectric barrier 20, with both ends of the electrode wire fixed to the dielectric barrier 20; wherein, the end of the electrode wire closest to the power supply component 1 forms the output terminal of the low-voltage electrode 22. This structural arrangement fixes both ends of the electrode wire to the dielectric barrier 20, preventing the electrode wire from detaching from the dielectric barrier 20.

[0047] In the specific implementation process, the dielectric barrier 20 is made of insulating materials such as ceramic, quartz, mica or glass.

[0048] In actual operation, the medium blocking component 20 is preferably made of ceramic material.

[0049] In actual operation, the high-voltage electrode 21 is made of conductive material, such as ink material or stainless steel sheet.

[0050] In actual operation, the low-voltage electrode 22 is made of stainless steel electrode wire. Simultaneously, when the stainless steel electrode wire is evenly wound around the dielectric barrier 20, it needs to cover a large area of ​​the dielectric barrier 20's surface. The starting and ending positions of the stainless steel electrode wire correspond to the top and bottom positions of the high-voltage electrode 21, respectively. This structural arrangement, using stainless steel for the electrode wire, effectively improves conductivity and reduces corrosion. Furthermore, evenly winding the electrode wire around the dielectric barrier 20 and covering a large area of ​​its surface increases the contact area with air and the discharge space, thereby increasing plasma generation and purification efficiency.

[0051] In the specific implementation process, such as Figure 6 and Figure 7 As shown, the dielectric blocking member 20 has a plurality of first positioning grooves 201 on the side near the first limiting member 4, and the plurality of first positioning grooves 201 are evenly spaced along the height direction of the dielectric blocking member 20; the dielectric blocking member 20 has a plurality of second positioning grooves 202 on the side near the second limiting member 5, and the plurality of second positioning grooves 202 are evenly spaced along the height direction of the dielectric blocking member 20; so as to position the electrode wire through the first positioning grooves 201 and the second positioning grooves 202.

[0052] In actual operation, when the electrode wire is wound, it is positioned in each of the first positioning grooves 201 and the second positioning grooves 202 so that the electrode wire can be evenly wound on the medium blocking member 20 through the first positioning grooves 201 and the second positioning grooves 202. At the same time, the first positioning grooves 201 and the second positioning grooves 202 can limit the electrode wire, thereby preventing the electrode wire from falling off the medium blocking member 20.

[0053] In actual operation, the connection process between the dielectric barrier 20 and the electrode wire is as follows: First, the starting end of the electrode wire is fixed to the surface of the dielectric barrier 20 through solder points 7, and the starting end of the electrode wire is close to either side of the dielectric barrier 20. At the same time, in order to strengthen the firmness, two solder points 7 are set at the starting position of the electrode wire, and these two solder points 7 are close to the two sides of the dielectric barrier 20 respectively. Then, after the starting position of the electrode wire is fixed, the electrode wire is wound around the surface of the dielectric barrier 20 according to the arrangement of the first positioning groove 201 and the second positioning groove 202. Finally, when the electrode wire is wound to the last turn, the end position of the electrode wire is fixed to the surface of the dielectric barrier 20 through a solder point 7, and this solder point 7 is close to either side of the dielectric barrier 20. At the same time, when fixing the end position of the electrode wire, the end end of the electrode wire (i.e., the output end of the low-voltage electrode 22) needs to be left so as to facilitate electrical connection with the grounding terminal of the power supply component 1.

[0054] In actual operation, the connection process between the plasma reaction component 2 and the power supply component 1 is as follows: the power supply terminal of the power supply component 1 is connected to one end of the first wire, and the other end of the first wire passes through the mounting hole and the connection hole in sequence and is connected to the input terminal of the high-voltage electrode 21 by welding. The grounding terminal of the power supply component 1 is connected to one end of the second wire, and the other end of the second wire passes through the mounting hole and is connected to the end of the electrode wire.

[0055] In the specific implementation process, such as Figure 4 and Figure 5 As shown, the first limiting groove 40 is provided with at least one first clearance hole 44, which is used to avoid the fixing point of the electrode wire and the dielectric blocking member 20; and / or, the second limiting groove 50 is provided with at least one second clearance hole 54, which is used to avoid the fixing point of the electrode wire and the dielectric blocking member 20.

[0056] In actual operation, the first limiting groove 40 is provided with two first clearance holes 44, which are spaced apart along the length of the first limiting groove 40. The second limiting groove 50 is provided with two second clearance holes 54, which are spaced apart along the length of the second limiting groove 50.

[0057] In the first embodiment of the fixing component 3 in the sterilization and deodorization device provided by this utility model, such as Figure 1 and Figure 8 As shown, the fixing component 3 includes: a base 30, which is disposed on the power supply component 1. The base 30 is provided with a mounting groove 300 that is adapted to at least one component of the limiting component. At least one component of the limiting component is inserted into the mounting groove 300, and the limiting component is connected to the power supply component 1 through the base 30.

[0058] In actual operation, the base 30 is mounted on the power supply component 1. This structural arrangement is adopted to save space.

[0059] In the specific implementation process, after assembling the plasma reaction component 2 with the first limiting component 4 and the second limiting component 5, the first base plate 42 and the second base plate 52 are installed in the mounting groove 300, and then the base 30 is fixed with the first limiting component 4 and the second limiting component 5 by two fasteners 8.

[0060] In actual operation, the two fasteners 8 are located on both sides of the base 30. Alternatively, the two fasteners 8 are located at the bottom of the base 30, and the two fasteners 8 are respectively set to correspond to the first limiting component 4 and the second limiting component 5.

[0061] In the specific implementation process, such as Figure 1 As shown, the fixing component 3 also includes: a mounting flange 9, which is disposed on the top of the power supply component 1 and is located between the base 30 and the power supply component 1. The sterilization and deodorization device is fixed to the plate structure such as the duct wall by the mounting flange 9.

[0062] In the second embodiment of the fixing component 3 in the sterilization and deodorization device provided by this utility model, such as Figure 9 As shown, there are multiple plasma reaction components 2 and multiple limiting components, with each plasma reaction component 2 corresponding to one of the multiple limiting components. All plasma reaction components 2 are electrically connected to the power supply component 1. The fixing component 3 includes a support base 31, on which multiple limiting components are mounted, spaced apart along the length of the support base 31. Each plasma reaction component 2 is mounted on the support base 31 via its corresponding limiting component. This mechanism allows multiple plasma reaction components 2 to be powered by a single power supply component 1, reducing manufacturing costs, saving installation space, and effectively saving energy. Simultaneously, it simplifies wiring and control, enabling centralized control.

[0063] In the specific implementation process, the fixing component 3 also includes multiple bases 30, which are disposed on the support base 31 and are spaced apart along the length of the support base 31. Each base 30 is corresponding to a multiple limiting component. Each base 30 is provided with a mounting groove 300 that is adapted to at least one of the limiting components. At least one part of each limiting component is disposed on the corresponding base 30, so that each limiting component can be installed on the support base 31 through each base 30.

[0064] In actual operation, the base 30 and the limiting component are fixed by fasteners 8.

[0065] In actual operation, the support base 31 is provided with a connecting port and a connecting channel communicating with the connecting port. The connecting channel extends along the length of the support base 31. The first wire and the second wire enter the connecting channel from the connecting port of the support base 31, so that the end of the first wire away from the power supply terminal of the power supply component 1 is connected to the input terminal of the high voltage electrode 21 in each plasma reaction component 2, and the end of the second wire away from the ground terminal of the power supply component 1 is connected to the output terminal of the low voltage electrode 22 in each plasma reaction component 2.

[0066] In actual operation, the base plate of the support 31 and the side plate of the support 31 are detachably connected. This structural design facilitates maintenance.

[0067] In the specific implementation process, such as Figure 9 As shown, the fixing component 3 also includes a mounting flange 9, which is located on the top of the power supply component 1. Connecting plates are provided on both sides of the support base 31. The fixing component passes through the connecting plates and the mounting flange 9 in sequence and connects to the plate structure such as the duct wall. This structural arrangement allows the power supply component 1 to be connected to the support base 31, while simultaneously allowing the sterilization and deodorization device to be fixed to the plate structure such as the duct wall via the mounting flange 9.

[0068] In this embodiment, a mesh-like low electrode is provided on the outer surface of the dielectric barrier 20 near the output terminal of the low-voltage electrode 22. The output terminal of the low electrode is located on the side of the dielectric barrier 20 near the power supply component 1. Both the output terminal of the low electrode and the output terminal of the low-voltage electrode 22 are electrically connected to the ground terminal of the power supply component 1. This structural arrangement improves the discharge efficiency through the mesh-like low electrode.

[0069] In actual operation, when the electrode wire is finished winding, the end of the electrode wire coincides with the output end of the low electrode. The end of the electrode wire, the output end of the low electrode, and the other end of the second wire are connected together by welding, so that the output end of the low electrode and the end of the electrode wire are both connected to the grounding terminal of the power supply component 1 through the second wire.

[0070] In this embodiment, as Figure 10 As shown, the sterilization and deodorization device further includes a protective component 6. Both ends of the protective component 6 are connected to the first limiting component 4 and the second limiting component 5, respectively. The protective component 6 is disposed at the top of the plasma reaction component 2. The protective component 6 has a mounting groove adapted to the plasma reaction component 2, extending along the length of the plasma reaction component 2. At least a portion of the plasma reaction component 2 is engaged within the mounting groove. This structural arrangement, by providing the protective component 6, further shields and protects the plasma reaction component 2.

[0071] In a specific embodiment, such as Figure 10 As shown, the protective component 6 includes: a first protective plate 60, one end of which is disposed at the top of the first limiting component 4, and the other end of which is disposed in a direction away from the first limiting component 4. A fifth slot adapted to the plasma reaction component 2 is provided on the side of the first protective plate 60 near the plasma reaction component 2, and the length of the fifth slot extends along the length direction of the plasma reaction component 2; the fifth slot communicates with the first slot 410. A second protective plate 61, one end of which is disposed at the top of the second limiting component 5, and the other end of which is disposed in a direction away from the second limiting component 5. A sixth slot adapted to the plasma reaction component 2 is provided on the side of the second protective plate 61 near the plasma reaction component 2, and the length of the sixth slot extends along the length direction of the plasma reaction component 2; the sixth slot communicates with the third slot 510. The first protective plate 60 and the second protective plate 61 are disposed opposite each other, and the fifth and sixth slots form a mounting groove.

[0072] In actual operation, the first protection plate 60 and the second protection plate 61 are detachably connected.

[0073] In this embodiment, as Figure 1 , Figure 8 and Figure 9 As shown, the power supply component 1 includes an electrical housing 11 and a cover plate 12. The electrical housing 11 has a mounting cavity and a mounting port communicating with the mounting cavity. The power supply terminal and grounding terminal of the power supply component 1 are installed in the mounting cavity. The cover plate 12 matches the mounting port and is disposed on the mounting port. The cover plate 12 is detachably connected to the electrical housing 11 to seal the mounting port. This structural arrangement, which makes the cover plate 12 and the electrical housing 11 detachably connected, facilitates electrical maintenance.

[0074] In the specific implementation process, the power supply terminal of the power supply component 1 is connected to the external power supply through the power supply line 10.

[0075] In another embodiment of the low-pressure electrode 22 in the sterilization and deodorization device provided by this utility model, the low-pressure electrode 22 has a mesh structure. Furthermore, when the low-pressure electrode 22 has a mesh structure, neither the first positioning groove 201 nor the second positioning groove 202 needs to be provided on the first limiting component 4 or the second limiting component 5.

[0076] This utility model provides a sterilization and deodorization device, which includes: a power supply component 1 and a plasma reaction component 2. The power supply component 1 is electrically connected to the plasma reaction component 2 and is used to supply power to the plasma reaction component 2. The plasma reaction component 2 includes: a dielectric barrier 20, a high-voltage electrode 21, and a low-voltage electrode 22. The dielectric barrier 20 is provided with a receiving cavity adapted to the high-voltage electrode 21. The high-voltage electrode 21 is disposed in the receiving cavity. The dielectric barrier 20 and the high-voltage electrode 21 are integrally formed. The power supply terminal of the power supply component 1 is electrically connected to the input terminal of the high-voltage electrode 21 through a first wire passing through the dielectric barrier. The low-voltage electrode 22 is sleeved on the dielectric barrier 20. The side of the low-voltage electrode 22 closest to the dielectric barrier 20 is in contact with the dielectric barrier 20. The output terminal of the low-voltage electrode 22 is electrically connected to the ground terminal of the power supply component 1.

[0077] As can be seen, the sterilization and deodorization device provided by this utility model simply sets up a power supply component 1 and a plasma reaction component 2. The plasma reaction component 2 consists of a dielectric barrier 20, a high-voltage electrode 21, and a low-voltage electrode 22. The high-voltage electrode 21 is disposed within a cavity adapted to the dielectric barrier 20, and the dielectric barrier 20 and the high-voltage electrode 21 are integrally formed. The power supply terminal of the power supply component 1 is connected to the input terminal of the high-voltage electrode 21 through a first wire passing through the dielectric barrier, and the output terminal of the low-voltage electrode 22 is electrically connected to the ground terminal of the power supply component 1. It is evident that placing the high-voltage electrode 21 within the cavity of the dielectric barrier 20 can protect the high-voltage electrode 21, and the integral formation of the dielectric barrier 20 and the high-voltage electrode 21 can prevent water vapor or water from entering the cavity through the dielectric barrier 20, thereby improving the service life of the plasma reaction component and reducing maintenance costs. Meanwhile, by integrally molding the dielectric barrier 20 and the high-voltage electrode 21, there is no air between them, improving the safety and stability of the equipment. This sterilization and deodorization device boasts advantages such as a simple and compact structure, low discharge voltage, convenient assembly and maintenance, ultra-low ozone release, high plasma density, high sterilization efficiency, and wide applicability.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
