[0002] In some enclosed spaces, there are common problems such as small space and poor air circulation. Furthermore, as the enclosed time gradually increases, a series of problems such as aerosol pollution, microbial growth, and the generation of various odors seriously threaten human respiratory health.

[0003] Traditional methods for space disinfection and sterilization are numerous, such as high temperature, steam, and chemical disinfection. However, these methods often involve high energy consumption and the risk of overdosing. For public areas, methods typically include ultraviolet (UV) irradiation, ozone disinfection, and peracetic acid aerosol spraying. While these methods offer good air and surface sterilization effects, they have limitations. UV light only acts on object surfaces and has limited penetration, resulting in a limited sterilization range. Ozone and peracetic acid can damage sensitive and precision instruments and are toxic to humans.

Detailed Implementation

[0040] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0041] In some enclosed spaces, there are common problems such as small space and poor air circulation. Furthermore, as the enclosed time gradually increases, a series of problems such as aerosol pollution, microbial growth, and the generation of various odors seriously threaten human respiratory health.

[0042] Traditional methods for space disinfection and sterilization are numerous, such as high temperature, steam, and chemical disinfection. However, these methods often involve high energy consumption and the risk of overdosing. For public areas, methods typically include ultraviolet (UV) irradiation, ozone disinfection, and peracetic acid aerosol spraying. While these methods offer good air and surface sterilization effects, they have limitations. UV light only acts on object surfaces and has limited penetration, resulting in a limited sterilization range. Ozone and peracetic acid can damage sensitive and precision instruments and are toxic to humans. Furthermore, personnel must be isolated outside the enclosed space during the sterilization process, significantly reducing the convenience of sterilization.

[0043] Based on the aforementioned technical problems, an embodiment of the present invention is proposed. This embodiment may include a water storage tank 1, at least one discharge tip 2, and a discharge net 3. The water storage tank 1 contains a water storage cavity 101. The discharge tip 2 is located at the bottom of the water storage tank 1 and has a water guiding hole 201. The water guiding hole 201 is connected to the liquid path of the water storage cavity 101. The cross-sectional area of ​​the water guiding hole 201 in the horizontal direction gradually decreases from the direction closer to the water storage tank 1 to the direction farther away from the water storage tank 1, so that the water sprayed from the water guiding hole 201 is in a mist form. The discharge net 3 is installed at the bottom of the water storage tank 1 and surrounds the discharge tip 2. The discharge net 3 is grounded. When the discharge tip 2 is connected to a high voltage, a discharge region is formed between the discharge tip 2 and the discharge net 3, generating plasma, which forms a plasma spray with the water sprayed from the water guiding hole 201. This allows for the expansion of the sterilization range through plasma spraying, enabling human-machine coexistence. The compact structure allows it to be directly suspended in areas requiring sterilization, thereby improving the convenience of sterilization in enclosed spaces.

[0044] Reference Figures 1-6 This invention provides a sterilization component, which may include a water storage tank 1, at least one discharge tip 2, and a discharge net 3. The water storage tank 1 is provided with a water storage cavity 101. The discharge tip 2 is located at the bottom of the water storage tank 1 and has a water guiding hole 201, wherein the water guiding hole 201 is connected to the liquid path of the water storage cavity 101.

[0045] The cross-sectional area of ​​the water guiding hole 201 in the horizontal direction gradually decreases from the direction near the water storage tank 1 to the direction away from the water storage tank 1, so that the water sprayed from the water guiding hole 201 is in the form of a mist. The discharge net 3 is installed at the bottom of the water storage tank 1 and surrounds the discharge tip 2, wherein the discharge net 3 is grounded. When the discharge tip 2 is connected to high voltage, a discharge area is formed between the discharge tip 2 and the discharge net 3 to generate plasma, which forms a plasma spray with the water sprayed from the water guiding hole 201.

[0046] In this embodiment of the invention, the sterilization component includes at least a water storage tank 1, at least one discharge tip 2, and a discharge mesh 3. The water storage tank 1 has a water storage cavity 101 for storing water. The opening of the water storage cavity 101 faces upwards, and the water storage tank 1 can be made of metal.

[0047] The discharge tip 2 is made of a conductive material, such as a metal. The discharge tip 2 is electrically connected to a high-voltage power supply, and the discharge grid 3 is electrically connected to a grounding terminal. The voltage range of the high-voltage power supply can be between 3 and 8 kV. Thus, corona discharge can be achieved through the structural cooperation between the discharge tip 2 and the discharge grid 3. High-voltage breakdown of the air medium can ionize neutral gas into a plasma containing strongly oxidizing gaseous phases such as O3 (ozone), NO2 (nitrogen dioxide), and NO (nitric oxide), i.e., plasma gas.

[0048] The discharge tip 2 is fixedly connected to the water storage tank 1, and a water guiding hole 201 is provided in the vertical direction of the discharge tip 2. The water guiding hole 201 completely penetrates the discharge tip 2 and is connected to the liquid path of the water storage cavity 101, so that water in the water storage cavity 101 can be introduced into the discharge tip 2 through the water guiding hole 201. The cross-sectional area of ​​the water guiding hole 201 in the horizontal direction gradually decreases from the direction closer to the water storage tank 1 to the direction farther away from the water storage tank 1. In other words, the cross-sectional area of ​​the water guiding hole 201 in the horizontal direction gradually decreases from top to bottom, and finally forms a pinhole at the tip of the discharge tip 2 (also called the bottom of the discharge tip 2), so that the water sprayed from the discharge tip 2 is in the form of a mist.

[0049] The fusion of gaseous plasma and aqueous solution can generate a wide variety of reactive oxygen and nitrogen particles, such as O3 (ozone), H2O2 (hydrogen peroxide), NO2- (nitrite ions), NO3- (nitrate ions), O (oxygen ions), OH- (hydroxyl ions), and NO (nitric oxide). This gas-liquid mixture, coated with an aqueous phase, is released into the environment via plasma spraying, achieving excellent sterilization effects with a wide sterilization range and thorough coverage. Specifically, the reactive oxygen and nitrogen particles directly impact microorganisms, altering their surface structure, disrupting the integrity of the outer cell membrane, and damaging intracellular components, thus achieving sterilization.

[0050] The discharge net 3 is fixedly installed at the bottom of the water storage tank 1, and the discharge net 3 surrounds the discharge tip 2. Firstly, the discharge net 3 ensures that the plasma spray is released evenly from the net 3, expanding the sterilization range of the plasma spray. Secondly, the surrounding of the discharge tip 2 by the discharge net 3 makes the corona discharge more uniform, allowing for the generation of more plasma gas in the discharge area formed between the discharge net 3 and the discharge tip 2. Thirdly, the mesh structure of the discharge net 3 also serves as a visual observation port, allowing users to check whether the discharge tip 2 is functioning properly, thus facilitating routine maintenance.

[0051] Furthermore, when corona discharge occurs between the discharge tip 2 and the discharge grid 3, an ion wind can be generated simultaneously. For example, when the voltage of the high-voltage power supply is between 3 and 8 kV, the wind speed of the generated ion wind can reach up to 0.59 m / s. Therefore, during the corona discharge process, the outward diffusion speed of the plasma spray can be increased, thereby further expanding the sterilization range. The sterilization component also allows for human-machine coexistence, meaning that the user can remain in the current sterilization environment while the sterilization component is performing sterilization. Moreover, the sterilization component has a simple structure and small size. During use, it can be directly suspended in the area requiring sterilization, thereby improving the convenience of sterilization in enclosed spaces.

[0052] An optional embodiment of the invention, referring to... Figure 1 , Figure 2 as well as Figure 3 As shown, when there are at least two discharge tips 2, the at least two discharge tips 2 are distributed at intervals at the bottom of the water storage tank 1. The water storage tank 1 is connected to high voltage to power the at least two discharge tips 2, and an insulating layer 4 is provided at the connection between the water storage tank 1 and the discharge network 3.

[0053] In this embodiment of the invention, when there are at least two discharge tips 2, the at least two discharge tips 2 are distributed horizontally at intervals at the bottom of the water storage tank 1. For example, the at least two discharge tips 2 can be evenly distributed. Furthermore, a high-voltage power supply can be electrically connected to the water storage tank 1, thereby allowing the water storage tank 1 to act as a conductive element, simultaneously supplying power to multiple discharge tips 2 connected to the water storage tank 1, thus improving power supply convenience. Moreover, to avoid direct contact between the positive and negative electrodes, an insulating layer 4 is provided at the connection between the water storage tank 1 and the discharge mesh 3. The insulating layer 4 is fixed inside the water storage tank 1, and the discharge mesh 3 is fixed to the insulating layer 4. The number of discharge meshes 3 is adapted to the number of discharge tips 2; that is, each discharge mesh 3 encloses one discharge tip 2. Those skilled in the art can also use an insulating coating or an insulating shell on the outer surface of the water storage tank 1 for electrical insulation, thereby improving the safety performance of the sterilization component; however, no further limitations are imposed here.

[0054] The cross-sectional shape of the insulating layer 4 in the horizontal direction is adapted to the cross-sectional shape of the discharge grid 3 in the horizontal direction. In some embodiments, both the cross-sectional shape of the insulating layer 4 and the cross-sectional shape of the discharge grid 3 can be annular, wherein the annular shape can include square annular and circular annular, etc. (Refer to...) Figure 2 As shown, in a preferred embodiment, the cross-sectional shape of the insulating layer 4 and the cross-sectional shape of the discharge grid 3 can both be annular.

[0055] In one optional embodiment of the invention, the mesh size of the discharge mesh 3 is set between 40 and 60 meshes.

[0056] In this embodiment of the invention, the mesh count refers to the number of mesh openings arranged along the one-inch length of the discharge mesh 3. The mesh count of the discharge mesh 3 is set between 40 and 60 meshes. This ensures clear observation of the discharge at the discharge tip 2 and also slows down the outward diffusion rate of the plasma gas within the confines of the discharge mesh 3. Consequently, the plasma gas and aqueous solution can fully mix in the discharge space formed between the discharge mesh 3 and the discharge tip 2, generating a wide variety of active oxygen and active nitrogen particles. The aqueous-coated gas-liquid mixture is then released into the environment via plasma spraying, achieving excellent sterilization effects, a wide sterilization range, and thorough disinfection.

[0057] Those skilled in the art can determine the mesh count of the discharge mesh 3 according to actual design requirements. For example, the mesh count of the discharge mesh 3 can be 40 mesh, 50 mesh, or 60 mesh, etc., without further limitation.

[0058] An optional embodiment of the invention, referring to... Figure 1 and Figure 2 As shown, the discharge tip 2 has a conical structure.

[0059] In this embodiment of the invention, the discharge tip 2 can be a conical structure. That is, when the cross-sectional area of ​​the water guide hole 201 in the horizontal direction gradually decreases from the direction closer to the water storage tank 1 to the direction farther away from the water storage tank 1, the wall thickness of the discharge tip 2 can be ensured to be uniform from top to bottom. On the other hand, the conical discharge tip 2 can be located at the center of the discharge mesh 3, thereby making the distance from the periphery of the discharge tip 2 to the discharge mesh 3 consistent, which can improve the discharge uniformity of the discharge tip 2 and improve the processing convenience of the discharge tip 2.

[0060] An optional embodiment of the invention, referring to... Figure 1 and Figure 3 As shown, the sterilization component may include a water storage tank 1, at least one discharge tip 2, a discharge mesh 3, a molecular sieve layer 5, an insulating frame 6, and a heating element 7. The water storage tank 1 is provided with a water storage cavity 101. The discharge tip 2 is located at the bottom of the water storage tank 1 and has a water guiding hole 201, wherein the water guiding hole 201 is connected to the liquid path of the water storage cavity 101.

[0061] The cross-sectional area of ​​the water guiding hole 201 in the horizontal direction gradually decreases from the direction near the water storage tank 1 to the direction away from the water storage tank 1, so that the water sprayed from the water guiding hole 201 is in the form of a mist. The discharge net 3 is installed at the bottom of the water storage tank 1 and surrounds the discharge tip 2, wherein the discharge net 3 is grounded. When the discharge tip 2 is connected to high voltage, a discharge area is formed between the discharge tip 2 and the discharge net 3 to generate plasma, which forms a plasma spray with the water sprayed from the water guiding hole 201.

[0062] The molecular sieve layer 5 is disposed above the water storage tank 1 to enclose the water storage cavity 101, and the molecular sieve layer 5 is provided with flow guide holes 501. The insulating frame 6 is installed above the molecular sieve layer 5 to cooperate with the molecular sieve layer 5 to form an airflow channel 601, wherein the insulating frame 6 is provided with a water inlet hole 602. The heating element 7 is fixed on the insulating frame 6 and located in the airflow channel 601, so that the operation of the heating element 7 generates positive pressure on the water in the water storage cavity 101.

[0063] In this embodiment of the invention, the sterilization component includes at least a water storage tank 1, at least one discharge tip 2, and a discharge mesh 3. The water storage tank 1 has a water storage cavity 101 for storing water. The opening of the water storage cavity 101 faces upwards, and the water storage tank 1 can be made of metal.

[0064] The discharge tip 2 is made of a conductive material, such as a metal. The discharge tip 2 is electrically connected to a high-voltage power supply, and the discharge grid 3 is electrically connected to a grounding terminal. The voltage range of the high-voltage power supply can be between 3 and 8 kV. Thus, corona discharge can be achieved through the structural cooperation between the discharge tip 2 and the discharge grid 3. High-voltage breakdown of the air medium can ionize neutral gas into a gaseous plasma containing O3 (ozone), NO2 (nitrogen dioxide), and NO (nitric oxide), i.e., plasma gas.

[0065] The discharge tip 2 is fixedly connected to the water storage tank 1, and a water guiding hole 201 is provided in the vertical direction of the discharge tip 2. The water guiding hole 201 completely penetrates the discharge tip 2 and is connected to the liquid path of the water storage cavity 101, so that water in the water storage cavity 101 can be introduced into the discharge tip 2 through the water guiding hole 201. The cross-sectional area of ​​the water guiding hole 201 in the horizontal direction gradually decreases from the direction closer to the water storage tank 1 to the direction farther away from the water storage tank 1. In other words, the cross-sectional area of ​​the water guiding hole 201 in the horizontal direction gradually decreases from top to bottom, and finally forms a pinhole at the tip of the discharge tip 2 (also called the bottom of the discharge tip 2), so that the water sprayed from the discharge tip 2 is in the form of a mist.

[0066] The fusion of gaseous plasma and aqueous solution can generate a wide variety of reactive oxygen and nitrogen particles, such as O3 (ozone), H2O2 (hydrogen peroxide), NO2- (nitrite ions), NO3- (nitrate ions), O (oxygen ions), OH- (hydroxyl ions), and NO (nitric oxide). This gas-liquid mixture, coated with an aqueous phase, is released into the environment via plasma spraying, achieving excellent sterilization effects with a wide sterilization range and thorough coverage. Specifically, the reactive oxygen and nitrogen particles directly impact microorganisms, altering their surface structure, disrupting the integrity of the outer cell membrane, and damaging intracellular components, thus achieving sterilization.

[0067] The discharge net 3 is fixedly installed at the bottom of the water storage tank 1, and the discharge net 3 surrounds the discharge tip 2. Firstly, the discharge net 3 ensures that the plasma spray is released evenly from the net 3, expanding the sterilization range of the plasma spray. Secondly, the surrounding of the discharge tip 2 by the discharge net 3 makes the corona discharge more uniform, allowing for the generation of more plasma gas in the discharge area formed between the discharge net 3 and the discharge tip 2. Thirdly, the mesh structure of the discharge net 3 also serves as a visual observation port, allowing users to check whether the discharge tip 2 is functioning properly, thus facilitating routine maintenance.

[0068] Furthermore, when corona discharge occurs between the discharge tip 2 and the discharge grid 3, an ion wind can be generated simultaneously. For example, when the voltage of the high-voltage power supply is between 3 and 8 kV, the wind speed of the generated ion wind can reach up to 0.59 m / s. Therefore, during the corona discharge process, the outward diffusion speed of the plasma spray can be increased, thereby further expanding the sterilization range. The sterilization component also allows for human-machine coexistence, meaning that the user can remain in the current sterilization environment while the sterilization component is performing sterilization. Moreover, the sterilization component has a simple structure and small size. During use, it can be directly suspended in the area requiring sterilization, thereby improving the convenience of sterilization in enclosed spaces.

[0069] The molecular sieve layer 5 can be made of molecular sieve material. A molecular sieve can be understood as a synthetically produced hydrated aluminosilicate (zeolite) or natural zeolite that has a sieving effect on molecules. For example, the molecular sieve layer 5 can be formed by encapsulating a molecular sieve within a shell. Thus, the molecular sieve layer 5 allows air to pass through, but water cannot pass through it. The molecular sieve layer 5 can be positioned above the water storage tank 1 to form a closed loop in the water storage cavity 101, and the molecular sieve layer 5 is provided with a flow guide hole 501 for injecting water into the water storage cavity 101.

[0070] The insulating frame 6 is installed above the molecular sieve layer 5 and fixedly connected to the water storage tank 1. The insulating frame 6 can be made of insulating resin or insulating plastic. In some embodiments, the insulating frame 6 is made of polybutylene terephthalate (PBT). In other embodiments, the insulating frame 6 is made of polyethylene glycol terephthalate (PET). In still other embodiments, the insulating frame 6 can also be made of epoxy resin glass fiber laminate (also known as epoxy fiberglass). This allows the insulating frame 6 to have advantages such as good heat resistance and excellent electrical insulation. The molecular sieve layer 5 can be fixed to the insulating frame 6. The insulating frame 6 and the molecular sieve layer 5 cooperate to form an airflow channel 601. A water inlet 602 is provided on the insulating frame 6, located above the guide hole 501, for injecting water into the water storage cavity 101.

[0071] The heating element 7 is fixed to the insulating frame 6 and located in the airflow channel 601. For example, there can be multiple heating elements 7, positioned at the top of the airflow channel 601. Changes in air temperature can generate different pressure changes in the airflow channel 601, thereby increasing the air pressure and pushing air into the water storage chamber 101, providing the power for water atomization from the discharge tip 2. This increases the amount of water atomized by the discharge tip 2 and further improves the efficiency of plasma gas and atomized water fusion, thus enhancing the sterilization efficiency of the sterilization component.

[0072] For example, the atomized water volume can be directly proportional to the heating temperature. When the air temperature in the airflow channel 601 reaches 60°C, the atomized water volume is 200 ml / h; when the air temperature in the airflow channel 601 reaches 40°C, the atomization volume is 120 ml / h.

[0073] In one optional embodiment of the invention, the height between the bottom of the discharge grid 3 and the discharge tip 2 is set between 25 and 35 mm.

[0074] In this embodiment of the invention, the height between the bottom of the discharge mesh 3 and the discharge tip 2 can be controlled between 25 and 35 mm. This ensures that the structure of the discharge mesh 3 is miniaturized while maximizing the discharge space between the discharge mesh 3 and the discharge tip 2. This facilitates the full fusion of plasma gas and atomized water before its release from the discharge mesh 3, thereby improving the product performance of the sterilization component.

[0075] An optional embodiment of the invention, referring to... Figure 1 and Figure 3 As shown, the sterilization component may include a water storage tank 1, at least one discharge tip 2, a discharge mesh 3, a molecular sieve layer 5, an insulating frame 6, a heating element 7, a float 8, a connecting rod 9, a support plate 10, and a stop valve 11. The water storage tank 1 contains a water storage cavity 101. The discharge tip 2 is located at the bottom of the water storage tank 1 and has a water guiding hole 201, which is connected to the liquid path of the water storage cavity 101. The cross-sectional area of ​​the water guiding hole 201 in the horizontal direction gradually decreases from the direction near the water storage tank 1 to the direction away from the water storage tank 1, so that the water sprayed from the water guiding hole 201 is in a mist form. The discharge mesh 3 is installed at the bottom of the water storage tank 1 and surrounds the discharge tip 2, wherein the discharge mesh 3 is grounded. When a high voltage is applied to the discharge tip 2, a discharge region is formed between the discharge tip 2 and the discharge grid 3 to generate plasma, which then forms a plasma spray with the water sprayed from the water guide hole 201.

[0076] The molecular sieve layer 5 is disposed above the water storage tank 1 to enclose the water storage cavity 101, and the molecular sieve layer 5 is provided with flow guide holes 501. The insulating frame 6 is installed above the molecular sieve layer 5 to cooperate with the molecular sieve layer 5 to form an airflow channel 601, wherein the insulating frame 6 is provided with a water inlet hole 602. The heating element 7 is fixed on the insulating frame 6 and located in the airflow channel 601, so that the operation of the heating element 7 generates positive pressure on the water in the water storage cavity 101.

[0077] The float 8 is disposed in the water storage cavity 101. The connecting rod 9 is fixed to the float 8 and passes through the guide hole 501, wherein the connecting rod 9 passes through the insulating frame 6 and is slidably disposed with the insulating frame 6. The support plate 10 is fixed to the connecting rod 9 and is located in the airflow channel 601. The stop valve 11 is fixed to the support plate 10, wherein when the water storage cavity 101 is full of water, the float 8 is driven by buoyancy to raise the support plate 10, so that the stop valve 11 seals the water inlet 602.

[0078] In this embodiment of the invention, the sterilization component includes at least a water storage tank 1, at least one discharge tip 2, and a discharge mesh 3. The water storage tank 1 has a water storage cavity 101 for storing water. The opening of the water storage cavity 101 faces upwards, and the water storage tank 1 can be made of metal.

[0079] The discharge tip 2 is made of a conductive material, such as a metal. The discharge tip 2 is electrically connected to a high-voltage power supply, and the discharge grid 3 is electrically connected to a grounding terminal. The voltage range of the high-voltage power supply can be between 3 and 8 kV. Thus, corona discharge can be achieved through the structural cooperation between the discharge tip 2 and the discharge grid 3. High-voltage breakdown of the air medium can ionize neutral gas into a gaseous plasma containing O3 (ozone), NO2 (nitrogen dioxide), and NO (nitric oxide), i.e., plasma gas.

[0080] The discharge tip 2 is fixedly connected to the water storage tank 1, and a water guiding hole 201 is provided in the vertical direction of the discharge tip 2. The water guiding hole 201 completely penetrates the discharge tip 2 and is connected to the liquid path of the water storage cavity 101, so that water in the water storage cavity 101 can be introduced into the discharge tip 2 through the water guiding hole 201. The cross-sectional area of ​​the water guiding hole 201 in the horizontal direction gradually decreases from the direction closer to the water storage tank 1 to the direction farther away from the water storage tank 1. In other words, the cross-sectional area of ​​the water guiding hole 201 in the horizontal direction gradually decreases from top to bottom, and finally forms a pinhole at the tip of the discharge tip 2 (also called the bottom of the discharge tip 2), so that the water sprayed from the discharge tip 2 is in the form of a mist.

[0081] The fusion of gaseous plasma and aqueous solution can generate a wide variety of reactive oxygen and nitrogen particles, such as O3 (ozone), H2O2 (hydrogen peroxide), NO2- (nitrite ions), NO3- (nitrate ions), O (oxygen ions), OH- (hydroxyl ions), and NO (nitric oxide). This gas-liquid mixture, coated with an aqueous phase, is released into the environment via plasma spraying, achieving excellent sterilization effects with a wide sterilization range and thorough coverage. Specifically, the reactive oxygen and nitrogen particles directly impact microorganisms, altering their surface structure, disrupting the integrity of the outer cell membrane, and damaging intracellular components, thus achieving sterilization.

[0082] The discharge net 3 is fixedly installed at the bottom of the water storage tank 1, and the discharge net 3 surrounds the discharge tip 2. Firstly, the discharge net 3 ensures that the plasma spray is released evenly from the net 3, expanding the sterilization range of the plasma spray. Secondly, the surrounding of the discharge tip 2 by the discharge net 3 makes the corona discharge more uniform, allowing for the generation of more plasma gas in the discharge area formed between the discharge net 3 and the discharge tip 2. Thirdly, the mesh structure of the discharge net 3 also serves as a visual observation port, allowing users to check whether the discharge tip 2 is functioning properly, thus facilitating routine maintenance.

[0083] Furthermore, when corona discharge occurs between the discharge tip 2 and the discharge grid 3, an ion wind can be generated simultaneously. For example, when the voltage of the high-voltage power supply is between 3 and 8 kV, the wind speed of the generated ion wind can reach up to 0.59 m / s. Therefore, during the corona discharge process, the outward diffusion speed of the plasma spray can be increased, thereby further expanding the sterilization range. The sterilization component also allows for human-machine coexistence, meaning that the user can remain in the current sterilization environment while the sterilization component is performing sterilization. Moreover, the sterilization component has a simple structure and small size. During use, it can be directly suspended in the area requiring sterilization, thereby improving the convenience of sterilization in enclosed spaces.

[0084] The molecular sieve layer 5 can be made of molecular sieve material. A molecular sieve can be understood as a synthetically produced hydrated aluminosilicate (zeolite) or natural zeolite that has a sieving effect on molecules. For example, the molecular sieve layer 5 can be formed by encapsulating a molecular sieve within a shell. Thus, the molecular sieve layer 5 allows air to pass through, but water cannot pass through it. The molecular sieve layer 5 can be positioned above the water storage tank 1 to form a closed loop in the water storage cavity 101, and the molecular sieve layer 5 is provided with a flow guide hole 501 for injecting water into the water storage cavity 101.

[0085] The insulating frame 6 is installed above the molecular sieve layer 5 and fixedly connected to the water storage tank 1. The insulating frame 6 can be made of insulating resin or insulating plastic. In some embodiments, the insulating frame 6 is made of polybutylene terephthalate (PBT). In other embodiments, the insulating frame 6 is made of polyethylene glycol terephthalate (PET). In still other embodiments, the insulating frame 6 can also be made of epoxy resin glass fiber composite plastic (also known as epoxy fiberglass). This allows the insulating frame 6 to have advantages such as good heat resistance and excellent electrical insulation. The molecular sieve layer 5 can be fixed to the insulating frame 6. The insulating frame 6 and the molecular sieve layer 5 cooperate to form an airflow channel 601. A water inlet 602 is provided on the insulating frame 6, located above the guide hole 501, for injecting water into the water storage cavity 101.

[0086] The heating element 7 is fixed to the insulating frame 6 and located in the airflow channel 601. For example, there can be multiple heating elements 7, positioned at the top of the airflow channel 601. Changes in air temperature can generate different pressure changes in the airflow channel 601, thereby increasing the air pressure and pushing air into the water storage chamber 101, providing the power for water atomization from the discharge tip 2. This increases the amount of water atomized by the discharge tip 2 and further improves the efficiency of plasma gas and atomized water fusion, thus enhancing the sterilization efficiency of the sterilization component.

[0087] For example, the atomized water volume can be directly proportional to the heating temperature. When the air temperature in the airflow channel 601 reaches 60°C, the atomized water volume is 200 ml / h; when the air temperature in the airflow channel 601 reaches 40°C, the atomization volume is 120 ml / h.

[0088] The float 8 is disposed in the water storage cavity 101, allowing it to float following the liquid surface within the cavity. The connecting rod 9 is fixed to the float 8 and extends through the guide hole 501. Furthermore, the connecting rod 9 is vertically positioned and extends through the insulating frame 6. The connecting rod is slidably disposed with the insulating frame 6. Therefore, when the float 8 floats with the liquid surface, the current water level in the water storage cavity 101 can be observed based on the extension length of the connecting rod 9 located on the outer surface of the insulating frame 6.

[0089] The support plate 10 is horizontally positioned and fixed to the connecting rod 9. The support plate 10 is located within the airflow channel 601, and the stop valve 11 is fixed to the support plate 10. Thus, when the float 8 floats with the liquid level in the water storage cavity 101, the support plate 10 also changes height synchronously. For example, after the water storage cavity 101 is filled with water, the float 8 is located at the guide hole 501. At this time, the support plate 10 forms surface contact with the insulating frame 6, and the stop valve 11 seals the water inlet 602. This prevents external water from continuing to enter the airflow channel 601.

[0090] An optional embodiment of the invention, referring to... Figure 1 , Figure 4 and Figure 5 As shown, the sterilization component may further include a nut 12, which is located above the insulating frame 6 and is threadedly connected to the connecting rod 9 so that the water stop valve 11 and the water inlet 602 remain sealed.

[0091] In this embodiment of the invention, the nut 12 is located above the insulating frame 6 (also referred to as the outer surface of the insulating frame 6). The connecting rod 9 has an external thread, which connects to the internal thread of the nut 12, thereby limiting the position of the stop valve 11 and maintaining a seal between the water inlet 602 and the stop valve 11. Under the limiting effect of the nut 12, when the liquid level in the water storage cavity 101 drops, the float 8 will not drop with the liquid level. When the user needs to monitor the water volume, the nut 12 can be unscrewed to observe the extension length of the connecting rod 9.

[0092] An optional embodiment of the invention, referring to... Figure 3 and Figure 6 As shown, the sterilization component may further include a sealing plug 13, which is embedded in the water inlet 602 to seal the airflow channel 601.

[0093] In this embodiment of the invention, the sterilization component may further include a sealing plug 13. The sealing plug 13 is used to seal the water inlet 602 after the water storage cavity 101 is filled with water, thereby ensuring the airtightness of the airflow channel 601 during the operation of the sterilization component. Under the sealing effect of the sealing plug 13, when the liquid level in the water storage cavity 101 drops, the float 8 also drops with the liquid level. Therefore, by observing the extension length of the connecting rod 9, it can be determined whether water needs to be added to the water storage cavity 101.

[0094] In summary, this invention discloses a sterilization component, which may include a water storage tank 1, at least one discharge tip 2, and a discharge mesh 3. The water storage tank 1 contains a water storage cavity 101. The discharge tip 2 is located at the bottom of the water storage tank 1 and has a water guiding hole 201. The water guiding hole 201 is connected to the liquid path of the water storage cavity 101. The cross-sectional area of ​​the water guiding hole 201 in the horizontal direction gradually decreases from the direction near the water storage tank 1 to the direction away from the water storage tank 1, so that the water sprayed from the water guiding hole 201 is in a mist form. The discharge mesh 3 is installed at the bottom of the water storage tank 1 and surrounds the discharge tip 2. The discharge mesh 3 is grounded. When the discharge tip 2 is connected to a high voltage, a discharge region is formed between the discharge tip 2 and the discharge mesh 3 to generate plasma, which forms a plasma spray with the water sprayed from the water guiding hole 201. This allows for the expansion of the sterilization range through plasma spraying, enabling human-machine coexistence. The compact structure allows it to be directly suspended in areas requiring sterilization, thereby improving the convenience of sterilization in enclosed spaces.

The air handling device may be a sub-component of an electrical appliance; for example, in the case of a refrigerator, the air handling device may be an air humidifier integrated into the refrigerator.

The water storage tank 1 contains a water storage cavity 101. The discharge tip 2 is located at the bottom of the water storage tank 1 and has a water guiding hole 201. The water guiding hole 201 is connected to the liquid path of the water storage cavity 101. The cross-sectional area of ​​the water guiding hole 201 in the horizontal direction gradually decreases from the direction near the water storage tank 1 to the direction away from the water storage tank 1, so that the water sprayed from the water guiding hole 201 is in a mist form.
