[0059] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0060] The following describes a disinfection device 1 according to an embodiment of the present invention with reference to the accompanying drawings.

[0061] like Figure 1-Figure 8 As shown, the disinfection device 1 according to the embodiment of the present invention includes a housing 10 , a plasma generator 20 and a negative ion generator 30 .

[0062] The plasma generator 20 is arranged in the shell 10. The plasma generator 20 includes a first discharge part 210. After the plasma generator 20 is powered on, a strong electric field will be generated at the first discharge part 210. The generated strong electric field ionizes the surrounding air, thereby generating positive ions and negative ions. The generated positive ions and negative ions generate huge energy release at the moment of neutralization of positive and negative charges in the air, causing the surrounding bacterial structure to change and kill the surrounding bacteria, thereby achieving a sterilization effect to sterilize the air near the first discharge part 210.

[0063] Among them, the number of negative ions generated by ionization of the air around the first discharge part 210 is greater than the number of positive ions. The negative ions remaining after the neutralization of the positive ions and the negative ions can float in the air. The negative ions floating in the air will combine with the smoke and dust particles in the air to charge the smoke, dust and other particles. Due to the electrostatic effect, the charged smoke, dust and other particles are attracted to the ground and settle to the ground, thereby facilitating the improvement of air quality.

[0064] The negative ion generator 30 is arranged in the shell 10, and the negative ion generator 30 includes a second discharge part 310. After the negative ion generator 30 is powered on, the second discharge part 310 can generate high corona and release a large number of electrons. The electrons will be captured by oxygen molecules in the air to form air negative ions. After the air negative ions meet and combine with bacteria, they can change the structure of the bacteria or transfer the energy of the bacteria, and then eliminate the bacteria to achieve sterilization of the air near the second discharge part 310.

[0065] In addition, negatively charged air ions can undergo electrode neutralization with positively charged smoke, dust and other particles floating in the air, causing the smoke, dust and other particles to settle naturally, thereby facilitating the improvement of air quality.

[0066] The shell 10 defines a first installation space 11 and a second installation space 12 separated from each other. The first discharge section 210 is located in the first installation space 11, and the second discharge section 310 is located in the second installation space 12, so that the first discharge section 210 and the second discharge section 310 can work separately in independent spaces. The air in the first installation space 11 is ionized to produce positive ions and negative ions, and the air in the second installation space 12 is combined with electrons to form air negative ions. The first installation space 11 and the second installation space 12 are separated from each other to avoid the first discharge section 210 and the second discharge section 310 from influencing each other, and to avoid the positive ions and negative ions in the first installation space 11 from meeting the air negative ions in the second installation space 12, so as to ensure the air sterilization effect of the disinfection device 1.

[0067] In addition, the disinfection device 1 utilizes two generators, namely the plasma generator 20 and the negative ion generator 30, to sterilize the air. The disinfection device 1 can utilize one of the plasma generator 20 and the negative ion generator 30 for sterilization, or can utilize both the plasma generator 20 and the negative ion generator 30 for sterilization at the same time, thereby enriching the product functions of the disinfection device 1 and further facilitating the promotion and introduction of the disinfection device 1.

[0068] Therefore, the disinfection device 1 according to the embodiment of the present invention can use the plasma generator 20 for sterilization, and can also use the negative ion generator 30 for sterilization, which is convenient for enriching the sterilization function of the disinfection device 1 and achieving better publicity effect. At the same time, the shell 10 is used to separate the first discharge part 210 and the second discharge part 310 to avoid mutual influence between the plasma generator 20 and the negative ion generator 30, so as to ensure the sterilization effect of the disinfection device 1.

[0069] The following describes a disinfection device 1 according to a specific embodiment of the present invention with reference to the accompanying drawings.

[0070] like Figure 1-Figure 8As shown, the disinfection device 1 according to the embodiment of the present invention includes a housing 10 , a plasma generator 20 and a negative ion generator 30 .

[0071] In some embodiments of the present invention, one of the first installation space 11 and the second installation space 12 is located inside the shell 10, and the other of the first installation space 11 and the second installation space 12 is located outside the shell 10, so as to separate the first installation space 11 and the second installation space 12, and further separate the first discharge section 210 and the second discharge section 310, so that the first discharge section 210 can generate positive ions and negative ions inside the shell 10, and the second discharge section 310 can generate air negative ions outside the shell 10, thereby avoiding mutual influence between ions in the first installation space 11 and ions in the second installation space 12, thereby ensuring the sterilization effect of the disinfection device 1.

[0072] In some embodiments, the first installation space 11 is located inside the shell 10, and the second installation space 12 is located outside the shell 10. The shell 10 extends in the left-right direction, and the left side of the shell 10 is recessed to define a second installation space 12 outside the shell 10 on the left side of the shell 10; or, the right side of the shell 10 is recessed to define a second installation space 12 outside the shell 10 on the right side of the shell 10; or, the middle of the shell 10 is recessed to define a second installation space 12 outside the shell 10 in the middle of the shell 10; or, the middle of the shell 10 is convex to define a second installation space 12 outside the shell 10 on the left and right sides of the shell 10.

[0073] In other embodiments, the first installation space 11 is located outside the shell 10, the second installation space 12 is located inside the shell 10, the shell 10 extends in the left-right direction, and the left side of the shell 10 is recessed to define the first installation space 11 outside the shell 10 on the left side of the shell 10; or, the right side of the shell 10 is recessed to define the first installation space 11 outside the shell 10 on the right side of the shell 10; or, the middle part of the shell 10 is recessed to define the first installation space 11 outside the shell 10 in the middle part of the shell 10; or, the middle part of the shell 10 is convex to define the first installation space 11 outside the shell 10 on the left and right sides of the shell 10.

[0074] In some examples, such as Figure 3 As shown, the first installation space 11 is located inside the shell 10, and the second installation space 12 is located outside the shell 10, so that the second discharge section 310 is arranged outside the shell 10. Since the second discharge section 310 can release electrons and the number of electrons is large, the second discharge section 310 is arranged outside the shell 10 so that the electrons can fully combine with the oxygen outside the shell 10 to form enough negative air ions, thereby facilitating the use of negative air ions for sterilization.

[0075] In some other embodiments of the present invention, the first installation space 11 and the second installation space 12 are both located in the shell 10, and the first installation space 11 and the second installation space 12 are separated in the shell 10 to separate the first discharge section 210 and the second discharge section 310, so that the first discharge section 210 generates positive ions and negative ions in the first installation space 11, and the second discharge section 310 generates air negative ions in the second installation space 12, thereby avoiding mutual influence between ions in the first installation space 11 and ions in the second installation space 12, and avoiding affecting the sterilization effect of the disinfection device 1.

[0076] At the same time, the shell 10 is used to define an independent first installation space 11 and a second installation space 12, and the first discharge part 210 in the first installation space 11 and the second discharge part 310 in the second installation space 12 can also be protected to prevent objects in the external environment from scratching the first discharge part 210 and the second discharge part 310.

[0077] In some optional embodiments of the present invention, Figure 3 As shown, at least two first installation spaces 11 are defined in the housing 10 , and the middle portion of the housing 10 is recessed to define a second installation space 12 outside the housing 10 , and the second installation space 12 is located between the two first installation spaces 11 .

[0078] At least one first discharge section 210 is provided in each first installation space 11, so that the first discharge section 210 is used to ionize the air in the first installation space 11, thereby forming positive ions and negative ions in the first installation space 11. At least one second discharge section 310 is provided in the second installation space 12, so that the second discharge section 310 can release electrons in the second installation space 12, thereby forming air negative ions in the second installation space 12. The first discharge section 210 and the second discharge section 310 are separated by the shell 10 to avoid mutual influence between the first discharge section 210 and the second discharge section 310.

[0079] like Figure 3 As shown, in the present embodiment, two first installation spaces 11 and one second installation space 12 are defined in the shell 10, and the middle portion of the shell 10 is recessed inward to form a second installation space 12. The two first installation spaces 11 are spaced apart in the left-right direction in the shell 10, and the second installation space 12 is located outside the shell 10, so as to separate the first installation space 11 and the second installation space 12, thereby separating the first discharge section 210 and the second discharge section 310, thereby avoiding mutual influence between the first discharge section 210 and the second discharge section 310.

[0080] In some other optional embodiments of the present invention, at least two second installation spaces 12 are defined in the shell 10, and a central protrusion of the shell 10 is arranged to define second installation spaces 12 located outside the shell 10 on both sides of the shell 10, and the first installation space 11 is located between the two second installation spaces 12.

[0081] In some embodiments of the present invention, Figure 1 , Figure 3 As shown, the disinfection device 1 is suitable for being arranged in an air duct, and the first installation space 11 has a first air inlet 111 and a first air outlet 112. The first air inlet 111 and the first air outlet 112 are arranged relatively to each other in the air flow direction in the air duct. When the air flows in the air duct, the air can enter the first installation space 11 from the first air inlet 111, and the air in the first installation space 11 can flow from the first air outlet 112 to the designated area.

[0082] Among them, the first air inlet 111 and the first air outlet 112 are arranged relatively to each other in the air flow direction in the air duct. For example, when the air flow flows in the front-to-back direction, the first air inlet 111 and the first air outlet 112 are arranged opposite to each other in the front-to-back direction. This can reduce the flow path of the air in the first installation space 11, so that the positive ions and negative ions in the first installation space 11 can flow smoothly to the designated area with the air, avoiding that the ions are blown onto the inner wall of the first installation space 11 when the ions flow to the designated area with the air.

[0083] It should be understood here that the aforementioned front-to-back direction is only described as an example and will not limit the flow direction of the airflow in the air duct.

[0084] Among them, the positive ions and negative ions in the first installation space 11 will flow to the designated area together with the air. On the one hand, the positive ions and negative ions are used to sterilize the environment in the designated area. On the other hand, the negative ions can combine with the smoke and dust particles in the designated area to make the smoke, dust and other particles charged. Due to the electrostatic effect, the charged smoke, dust and other particles are attracted to the ground and settle to the ground, thereby improving the air quality in the designated area.

[0085] like Figure 2 As shown, the second installation space 12 has a second air inlet 121 and a second air outlet 122, and the second air inlet 121 and the second air outlet 122 are arranged relatively to each other in the air flow direction in the air duct. When the air flows in the air duct, the air can enter the second installation space 12 from the second air inlet 121, and the air in the second installation space 12 flows from the second air outlet 122 to the designated area.

[0086] Among them, the second air inlet 121 and the second air outlet 122 are arranged relative to each other in the air flow direction in the air duct. For example, when the air flow flows in the front-to-back direction, the second air inlet 121 and the second air outlet 122 are arranged opposite to each other in the front-to-back direction. This makes it easy to reduce the flow path of air in the second installation space 12, so that the negative air ions in the second installation space 12 can flow smoothly to the designated area with the air, and avoid the negative air ions being blown onto the inner wall of the second installation space 12 when the negative air ions flow to the designated area with the air.

[0087] It should be understood here that the aforementioned front-to-back direction is only described as an example and will not limit the flow direction of the airflow in the air duct.

[0088] Among them, the negative air ions in the second installation space 12 flow to the designated area together with the air. On the one hand, the negative air ions can be used to sterilize the environment in the designated area. On the other hand, the negatively charged negative air ions can be electrode-neutralized with the positively charged smoke, dust and other particles floating in the air, so that the smoke, dust and other particles are naturally deposited, thereby improving the air quality in the designated area.

[0089] In some specific embodiments of the present invention, Figure 2 , Figure 6 As shown, the first installation space 11 is located in the shell 10, and the two oppositely arranged side walls of the shell 10 corresponding to the first installation space 11 are respectively provided with a grille structure 162 to form a first air inlet 111 and a first air outlet 112. The air in the air duct can enter the first installation space 11 from the first air inlet 111 through the grille structure 162, and flow from the first air outlet 112 to the designated area. The positive ions and negative ions in the first installation space 11 will flow to the designated area with the air, so as to utilize the positive ions and negative ions generated by the plasma generator 20 to sterilize the designated area.

[0090] A portion of the shell 10 is recessed to define a second installation space 12, and the second installation space 12 is located outside the shell 10. The opposite sides of the second installation space 12 are open to form a second air inlet 121 and a second air outlet 122. When the air in the air duct flows, the air can enter the second installation space 12 from the second air inlet 121 and flow to the designated area from the second air outlet 122. The negative air ions in the second installation space 12 will flow to the designated area with the air, so that the negative air ions generated by the negative ion generator 30 can be used to sterilize the designated area.

[0091] The second installation space 12 is located outside the shell, and the two opposite sides of the second installation space 12 are opened to form a second air inlet 121 and a second air outlet 122, so that the negative air ions in the second installation space 12 can easily flow to the designated area with the air.

[0092] like Figure 6 As shown, in the present embodiment, the front side wall and the rear side wall of the shell 10 constitute the front side wall and the rear side wall of the first installation space 11, and the front side wall and the rear side wall of the shell 10 are respectively provided with a grille structure 162 to form a first air inlet 111 and a first air outlet 112. When the air flows in the front-to-back direction, the air can enter the first installation space 11 from the first air inlet 111, and flow to the designated area from the first air outlet 112, so as to reduce the path of the air flowing in the first installation space 11, thereby allowing the positive ions and negative ions in the first installation space 11 to flow smoothly to the designated area.

[0093] In some embodiments of the present invention, the length direction of the shell 10 extends along the first direction, and the plasma generator 20 and the negative ion generator 30 are arranged in the first direction, so that the plasma generator 20 and the negative ion generator 30 are reasonably arranged at different positions of the shell 10, and at the same time, the shell 10 is conveniently used to separate the first discharge section 210 and the second discharge section 310 to avoid mutual influence between the first discharge section 210 and the second discharge section 310.

[0094] Among them, the number of at least one of the plasma generator 20 and the negative ion generator 30 is multiple, and the plasma generator 20 and the negative ion generator 30 are arranged in the first direction to make full use of the space defined by the shell 10. The plasma generator 20 and the negative ion generator 30 are set at appropriate positions on the shell 10, and the plasma generator 20 is used to generate sufficient positive ions and negative ions, and the negative ion generator 30 is used to generate sufficient air negative ions, thereby facilitating the improvement of the disinfection efficiency of the disinfection device 1.

[0095] For example, the disinfection device 1 includes multiple plasma generators 20 and one negative ion generator 30; or, the disinfection device 1 includes one plasma generator 20 and multiple negative ion generators 30; or, the disinfection device 1 includes multiple plasma generators 20 and multiple negative ion generators 30. When designing the number of plasma generators 20 and negative ion generators 30 in the disinfection device 1, it can be specifically determined according to the size of the required disinfection range.

[0096] In some embodiments, Figure 3 As shown, the first direction extends along the left-right direction, and the shell 10 defines two first installation spaces 11 and one second installation space 12. The first installation space 11 is located inside the shell 10, and the second installation space 12 is located outside the shell 10. The two first installation spaces 11 are located on the left and right sides of the second installation space 12.

[0097] The disinfection device 1 includes two plasma generators 20 and a negative ion generator 30. The negative ion generator 30 is arranged between the two plasma generators 20. The plasma generator 20 includes a plurality of first discharge sections 210. The negative ion generator 30 includes a plurality of second discharge sections 310. The plurality of first discharge sections 210 are arranged in a first installation space 11 at intervals along the left-right direction, and the plurality of second discharge sections 310 are arranged in a second installation space 12 at intervals along the left-right direction, so that the first discharge section 210 can generate sufficient positive ions and negative ions, and the second discharge section 310 can generate sufficient air negative ions.

[0098] Specifically, multiple plasma generators 20 or multiple negative ion generators 30 are provided to increase the number of positive ions and negative ions generated by the plasma generator 20 and the number of air negative ions generated by the negative ion generator 30, thereby increasing the range of disinfection of the disinfection device 1 and improving the disinfection efficiency of the disinfection device 1.

[0099] In some embodiments of the present invention, Figure 7 As shown, the plasma generator 20 also includes a first positive electrode portion 220 and a first negative electrode portion 230, and the first positive electrode portion 220 and the first negative electrode portion 230 are both arranged in the first installation space 11, and the first positive electrode portion 220 and the first negative electrode portion 230 are arranged opposite to each other in the second direction. The first discharge portion 210 is formed on the side of the first negative electrode portion 230 facing the first positive electrode portion 220. After the first positive electrode portion 220 and the first negative electrode portion 230 are energized, a high voltage is formed between the first positive electrode portion 220 and the first negative electrode portion 230. At this time, a strong electric field is generated at the first discharge portion 210, and the air near the first discharge portion 210 is ionized by the strong electric field and generates a large number of positive ions and negative ions. The generated positive ions and negative ions generate huge energy release at the moment of neutralization of positive and negative charges in the air, thereby causing changes in the structure of bacteria around them or conversion of energy, thereby causing the death of bacteria and achieving its sterilization effect.

[0100] Among them, the negative ions produced after the air is ionized are more than the positive ions. The excess negative ions will float in the air. After the negative ions combine with the smoke, dust and other particles in the air, the smoke, dust and other particles will be charged. Due to the static electricity, the charged smoke, dust and other particles are attracted to the ground and settle to the ground, thereby improving the air quality.

[0101] In some optional embodiments of the present invention, the first positive electrode portion 220 and the first negative electrode portion 230 both form a plate-like structure, and the first discharge portion 210 is arranged on the peripheral side of the first negative electrode portion 230. After the first positive electrode portion 220 and the first negative electrode portion 230 are energized, a high voltage can be formed between the first positive electrode portion 220 and the first negative electrode portion 230, so that a strong voltage is formed at the first discharge portion 210 and a corona effect is generated, so that the air can be ionized to produce a large number of positive ions and negative ions.

[0102] Among them, the arc transition is formed at the corner of the peripheral side of the first negative electrode portion 230, so that the charges between the first negative electrode portion 230 and the first positive electrode portion 220 can be concentrated and accumulated at the first discharge portion 210, avoiding that the charges between the first negative electrode portion 230 and the first positive electrode portion 220 will accumulate at other positions of the first negative electrode portion 230, affecting the intensity of the electric field at the first discharge portion 210, and affecting the ionization of the surrounding air by the first discharge portion 210.

[0103] In some embodiments, the first positive electrode portion 220 is arranged horizontally, and the first negative electrode portion 230 is arranged horizontally, that is, the thickness directions of the first positive electrode portion 220 and the first negative electrode portion 230 extend in the same direction, and multiple first discharge portions 210 are arranged at intervals in the first negative electrode portion 230, and the first discharge portion 210 is placed perpendicular to the first negative electrode portion 230, so that the end of the first discharge portion 210 facing the first positive electrode portion 220 is located between the first positive electrode portion 220 and the first negative electrode portion 230, and then after the first positive electrode portion 220 and the first negative electrode portion 230 are energized, a strong electric field can be formed at the end of the first discharge portion 210 facing the first positive electrode portion 220.

[0104] In other embodiments, the first positive electrode portion 220 is arranged horizontally, and the first negative electrode portion 230 is arranged upright. The thickness directions of the first positive electrode portion 220 and the first negative electrode portion 230 are perpendicular to each other. A plurality of first discharge portions 210 are arranged at intervals on the first negative electrode portion 230. After the first discharge portion 210 is arranged on the first negative electrode portion 230, the first discharge portion 210 is placed upright on the first negative electrode portion 230 so that the first discharge portion 210 can be perpendicular to the first positive electrode portion 220, so that the end of the first discharge portion 210 facing the first positive electrode portion 220 is located between the first positive electrode portion 220 and the first negative electrode portion 230. Further, after the first positive electrode portion 220 and the first negative electrode portion 230 are energized, a strong electric field can be formed at the end of the first discharge portion 210 facing the first positive electrode portion 220.

[0105] like Figure 7 , Figure 8As shown, in this embodiment, the end of the first discharge portion 210 facing the first positive electrode portion 220 is formed as a first pointed end portion 211. After the first positive electrode portion 220 and the first negative electrode portion 230 are energized, a high voltage is formed between the first positive electrode portion 220 and the first negative electrode portion 230. A strong electric field can be formed at the first pointed end portion 211 of the first discharge portion 210, thereby forming a pointed discharge and generating a corona effect, so as to ionize the air near the first discharge portion 210, thereby generating positive ions and negative ions.

[0106] In some specific embodiments of the present invention, Figure 8 As shown, the plasma generator 20 includes a plurality of first discharge sections 210, and the plurality of first discharge sections 210 are spaced apart along the length direction of the first cathode section 230, so that the first cathode section 230 can supply power to the plurality of first discharge sections 210, so as to utilize the plurality of first discharge sections 210 to ionize the air near them, so as to expand the range of ionized air, thereby being able to generate more positive ions and negative ions.

[0107] In some optional embodiments of the present invention, Figure 8 As shown, the distance H between the first positive electrode portion 220 and the first negative electrode portion 230 in the second direction is 5 mm to 8 mm. If the distance H between the first positive electrode portion 220 and the first negative electrode portion 230 is too small, the air content between the first positive electrode portion 220 and the first negative electrode portion 230 will be too small. When the first discharge portion 210 ionizes the air, the content of positive ions and negative ions generated by ionization is low. If the distance H between the first positive electrode portion 220 and the first negative electrode portion 230 is too large, the intensity of the electric field formed on the first discharge portion 210 will be too small, which is not conducive to the ionization of the air by the first discharge portion 210.

[0108] Therefore, the distance H between the first positive electrode portion 220 and the first negative electrode portion 230 in the second direction is 5 mm to 8 mm to ensure the electric field strength formed at the first discharge portion 210 so that the first discharge portion 210 can ionize enough air to form enough positive ions and negative ions.

[0109] Optionally, the distance H between the first positive electrode portion 220 and the first negative electrode portion 230 in the second direction is 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, or 8 mm, so that a stronger electric field can be formed on the first discharge portion 210, so that the first discharge portion 210 can fully ionize the air to generate sufficient positive ions and negative ions.

[0110] like Figure 8As shown, in this embodiment, the second direction extends in the up-down direction, and the distance H between the first positive electrode portion 220 and the first negative electrode portion 230 in the up-down direction is 7 mm. The first discharge portion 210 is arranged at the upper end of the first negative electrode portion 230 to avoid the distance between the first positive electrode portion 220 and the first discharge portion 210 being too far, and then after the first positive electrode portion 220 and the first negative electrode portion 230 are energized, it is ensured that a high voltage can be formed between the first positive electrode portion 220 and the first negative electrode portion 230, so that a strong electric field can be generated at the first discharge portion 210, so that the first discharge portion 210 can ionize the air around it, and then generate positive ions and negative ions.

[0111] Among them, the first discharge portion 210 extends upward in the up-down direction, and the upper end of the first discharge portion 210 forms a first tip portion 211. After the first positive electrode portion 220 and the first negative electrode portion 230 are energized, a high voltage will be loaded between the first positive electrode portion 220 and the first negative electrode portion 230, and a strong electric field will be generated at the first tip portion 211 of the first discharge portion 210, so that the air around the first discharge portion 210 can be ionized, thereby generating positive ions and negative ions.

[0112] In some optional embodiments of the present invention, Figure 7 As shown, the negative ion generator 30 also includes a second negative electrode portion 320, and the second discharge portion 310 is connected to the second negative electrode portion 320. The second negative electrode portion 320 can provide a negative voltage to the second discharge portion 310 to utilize the second discharge portion 310 to generate a high corona, thereby enabling the second discharge portion 310 to release electrons and form negative air ions in the second installation space 12.

[0113] In some specific embodiments of the present invention, Figure 7 As shown, a positioning and mounting portion 321 is provided on the second negative electrode portion 320, and the positioning and mounting portion 321 protrudes from the second negative electrode portion 320, and the second discharge portion 310 is connected to the positioning and mounting portion 321, so that when the second discharge portion 310 is installed on the second negative electrode portion 320, the positioning and mounting portion 321 can be used to determine the position of the second discharge portion 310 on the second negative electrode portion 320, and then the second discharge portion 310 can be accurately installed at the specified position on the second negative electrode portion 320, so that the second negative electrode portion 320 can smoothly provide a negative voltage for the second discharge portion 310, so that the second discharge portion 310 can release electrons in the second installation space 12, and then form negative air ions in the second installation space 12.

[0114] like Figure 8As shown, in this embodiment, the second negative electrode portion 320 extends in the left-right direction, and the negative ion generator 30 includes two second discharge portions 310. Two positioning and mounting portions 321 are provided on the second negative electrode portion 320. The two positioning and mounting portions 321 are arranged on the second negative electrode portion 320 at intervals along the left-right direction. The two positioning and mounting portions 321 correspond one-to-one to the two second discharge portions 310. When installing the second discharge portion 310, the position of the second discharge portion 310 on the second negative electrode portion 320 along the left-right direction can be quickly determined, and then the second discharge portion 310 can be set at a specified position on the second negative electrode portion 320.

[0115] In some examples, the positioning mounting portion 321 protrudes from the second cathode portion 320 in the up and down directions, so that when the second discharge portion 310 is installed to the second cathode portion 320 , the position of the positioning mounting portion 321 can be quickly determined, thereby quickly determining the position of the second discharge portion 310 on the second cathode portion 320 .

[0116] Specifically, the second discharge portion 310 is arranged on the rear side of the positioning and mounting portion 321, and the second discharge portion 310 is connected to the rear side wall of the positioning and mounting portion 321 by welding to fix the second discharge portion 310 at a designated position on the second negative electrode portion 320, so that the second negative electrode portion 320 can provide a negative voltage for the second discharge portion 310.

[0117] In some embodiments, Figure 8 As shown, the second discharge portion 310 is a carbon brush, and the second negative electrode portion 320 is used to provide a negative voltage to the carbon brush, thereby generating a high corona at the end of the carbon brush and releasing a large number of electrons. The electrons will be captured by oxygen molecules in the air to form negative air ions. After the negative air ions meet and combine with bacteria, they can change the structure of the bacteria or transfer the energy of the bacteria, thereby eliminating the bacteria, thereby sterilizing the air near the second discharge portion 310.

[0118] In other embodiments, the second discharge portion 310 is a conductive material, and a second tip portion is formed at one end of the second discharge portion 310 away from the second cathode portion 320. The second cathode portion 320 can provide a negative voltage for the second discharge portion 310. At this time, a high corona can be generated at the second tip portion and a large number of electrons can be released. The electrons will be captured by oxygen molecules in the air to form negative air ions. After the negative air ions meet and combine with bacteria, they can change the structure of the bacteria or transfer the energy of the bacteria, thereby eliminating the bacteria, thereby sterilizing the air near the second discharge portion 310.

[0119] In some specific embodiments of the present invention, Figure 8As shown, the second negative electrode portion 320 is connected to the first negative electrode portion 230 so as to conduct electricity to the first negative electrode portion 230 and the second negative electrode portion 320 at the same time, so that the first negative electrode portion 230 can provide a negative voltage for the first discharge portion 210, and the second negative electrode portion 320 can provide a negative voltage for the second discharge portion 310. There is no need to provide negative voltages for the first discharge portion 210 and the second discharge portion 310 separately, which is convenient to reduce the complexity of the structure and save costs.

[0120] In some examples, the disinfection device 1 can control one of the plasma generator 20 and the negative ion generator 30 to work or control both of them to work.

[0121] In some examples, the disinfection device 1 has a first preset voltage and a second preset voltage, and the second preset voltage is higher than the first preset voltage. When the disinfection device 1 only needs the plasma generator 20 to work and the negative ion generator 30 is not working, the first positive electrode part 220 is energized, and the first negative electrode part 230 and the second negative electrode part 320 are energized with the first preset voltage. At this time, a strong electric field can be generated at the first discharge part 210.

[0122] When the disinfection device 1 only needs the negative ion generator 30 to work and the plasma generator 20 is not working, the first positive electrode part 220 is not energized, the first negative electrode part 230 and the second negative electrode part 320 are energized at the second preset voltage, and the second discharge part 210 releases electrons.

[0123] When the disinfection device 1 requires both the plasma generator 20 and the negative ion generator 30 to work, the first positive electrode part 220 is energized, and the first negative electrode part 230 and the second negative electrode part 320 are energized at a second preset voltage. At this time, a strong electric field can be generated at the first discharge part 210, and the second discharge part 210 will release electrons.

[0124] In some specific embodiments of the present invention, Figure 1 , Figure 3 As shown, the shell 10 includes a mounting seat 15 and a cover body 16, and the mounting seat 15 and the cover body 16 are detachably connected. A first mounting space 11 is defined between the mounting seat 15 and the cover body 16, and a second mounting space 12 is defined on the outer side of the cover body 16. The first discharge part 210 is arranged in the first mounting space 11, and the second discharge part 310 is arranged in the second mounting space 12, so as to separate the first discharge part 210 and the second discharge part 310, thereby avoiding mutual interference between the ions generated by the first discharge part 210 and the ions generated by the second discharge part 310, and avoiding affecting the disinfection efficiency of the disinfection device 1.

[0125] The detachable connection between the mounting seat 15 and the cover 16 facilitates the first discharging unit 210 to be disposed in the first mounting space 11 or to be removed from the first mounting space 11 , so as to facilitate the subsequent maintenance and replacement of the first discharging unit 210 .

[0126] like Figure 7 As shown, in this embodiment, the plasma generator 20 includes a first positive electrode portion 220 and a first negative electrode portion 230, and the first positive electrode portion 220 and the first negative electrode portion 230 are both arranged in the first installation space 11, the first positive electrode portion 220 is arranged on the top wall of the first installation space 11, and the first negative electrode portion 230 is arranged on the bottom wall of the first installation space 11. The plasma generator 20 includes a plurality of first discharge portions 210, and the plurality of first discharge portions 210 are arranged on the first negative electrode portion 230 at intervals along the left-right direction. After the first positive electrode portion 220 and the first negative electrode portion 230 are energized, the first tip portion 211 of the first discharge portion 210 will form a strong electric field and ionize the air near the first discharge portion 210, thereby generating positive ions and negative ions.

[0127] In some embodiments, Figure 6 As shown, a portion of the cover body 16 is recessed toward the mounting seat 15 to define a second mounting space 12, thereby separating the first mounting space 11 and the second mounting space 12. Since the first discharge portion 210 is disposed in the first mounting space 11 and the second discharge portion 310 is disposed in the second mounting space 12, the first discharge portion 210 and the second discharge portion 310 can be separated by the shell 10, thereby avoiding the first discharge portion 210 and the second discharge portion 310 from influencing each other.

[0128] In some embodiments, Figure 3 As shown, a third installation space 13 is also defined between the mounting seat 15 and the cover body 16, and the third installation space 13 is connected to the first installation space 11, wherein the second negative electrode portion 320 is arranged in the third installation space 13, so that the mounting seat 15 and the cover body 16 can be used to protect the second negative electrode portion 320 to prevent foreign objects from scratching the second negative electrode portion 320.

[0129] Among them, the cover body 16 is provided with a through hole 161, and the second discharge part 310 passes through the through hole 161 to be connected with the second negative electrode part 320, so that when the second discharge part 310 is set in the second installation space 12, the second discharge part 310 can be connected with the second negative electrode part 320, so that the second negative electrode part 320 can supply power to the second discharge part 310, and then a high corona can be generated at the end of the second discharge part 310, so that the second discharge part 310 can release electrons, and the electrons can generate negative air ions after combining with oxygen molecules in the air.

[0130] like Figure 3As shown, in this embodiment, the first negative electrode portion 230 is arranged in the first installation space 11, and the second negative electrode portion 320 is arranged in the third installation space 13, so that the first installation space 11 is connected with the third installation space 13, so as to facilitate the connection between the first negative electrode portion 230 and the second negative electrode portion 320, and further facilitate the simultaneous power supply of the first negative electrode portion 230 and the second negative electrode portion 320.

[0131] In some examples, such as Figure 6 As shown, the hole of the via 161 transitions along an arc to prevent charges from accumulating at the hole edge of the via 161 when a high corona is generated at the end of the second discharge portion 310, thereby preventing the discharge of the second discharge portion 310 from being affected, so that the second discharge portion 310 can smoothly release electrons, and the electrons combine with oxygen molecules in the second installation space 12 to generate negative air ions.

[0132] In some optional embodiments of the present invention, Figure 5 As shown, a limiting groove 151 is provided on the inner wall of the shell 10, and the first negative electrode portion 230 and / or the second negative electrode portion 320 cooperate with the limiting groove 151 to limit the position of the first negative electrode portion 230 and / or the second negative electrode portion 320, and then the first negative electrode portion 230 and / or the second negative electrode portion 320 are arranged on the inner wall of the shell 10 to prevent the first negative electrode portion 230 and / or the second negative electrode portion 320 from falling off from the inner wall of the shell 10 when the disinfection device 1 is moved.

[0133] In some specific embodiments of the present invention, a positioning portion is provided in the limiting groove 151, and a positioning matching portion 231 that cooperates with the positioning portion is provided on the first negative electrode portion 230 and / or the second negative electrode portion 320, so that when the first negative electrode portion 230 and / or the second negative electrode portion 320 are fixed on the shell 10, the positioning portion and the positioning matching portion 231 can be used to quickly determine the position of the first negative electrode portion 230 and / or the second negative electrode portion 320 in the limiting groove 151, thereby facilitating the rapid fixing of the first negative electrode portion 230 and / or the second negative electrode portion 320 in the limiting groove 151.

[0134] Among them, one of the positioning portion and the positioning matching portion 231 is formed as a positioning protrusion, and the other is formed as a positioning recess, so that the positioning portion and the positioning matching portion 231 can be used to determine the position of the first negative electrode portion 230 and / or the second negative electrode portion 320 in the limiting groove 151, and then the first negative electrode portion 230 and / or the second negative electrode portion 320 can be quickly installed in the limiting groove 151.

[0135] like Figure 5 , Figure 8As shown, in the present embodiment, a first limiting plate 171 and a second limiting plate 172 are provided in the shell 10, and the first limiting plate 171 and the second limiting plate 172 are spaced apart in the front-to-back direction to define a limiting groove 151, and the disinfection device 1 includes two first negative electrode parts 230 and one second negative electrode part 320, and the second negative electrode part 320 is provided between the two first negative electrode parts 230, and the second negative electrode part 320 is connected to the first negative electrode part 230.

[0136] A positioning recess is provided at the bottom of each first negative electrode part 230, and two positioning protrusions are provided on the bottom wall of the limiting groove 151. The two positioning protrusions are arranged at intervals along the left-right direction. The first negative electrode part 230 and the second negative electrode part 320 are plugged into and matched with the limiting groove 151. The positioning recess at the bottom of the first negative electrode part 230 cooperates with the positioning protrusion at the bottom of the limiting groove 151 to quickly determine the positions of the first negative electrode part 230 and the second negative electrode part 320 in the limiting groove 151 along the front-to-back direction and the left-to-right direction, so that the first negative electrode part 230 and the second negative electrode part 320 can be quickly fixed in the limiting groove 151.

[0137] In some examples, the first discharge portion 210 is arranged at the upper end of the first negative electrode portion 230, and the second discharge portion 310 is arranged on the rear side of the second negative electrode portion 320. The second limiting plate 172 is provided with an avoidance recess that is recessed backward to avoid the second discharge portion 310. When the first negative electrode portion 230 and the second negative electrode portion 320 are inserted into the limiting groove 151, the second discharge portion 310 can be located in the avoidance recess to avoid interference between the second limiting plate 172 and the second discharge portion 310.

[0138] The following is based on the attached Figure 9-12 An air conditioner 5 according to an embodiment of the present invention is described.

[0139] The air conditioner 5 according to the embodiment of the present invention comprises an air conditioner body 50 and the disinfection device 1 according to the above-mentioned embodiment of the present invention.

[0140] The air conditioner body 50 has an interconnected air outlet channel 51 and an air outlet 52. The disinfection device 1 is arranged in the air outlet channel 51 to purify the air in the air outlet channel 51 using the disinfection device 1. At the same time, when the air in the air outlet channel 51 flows, the air flowing through the first installation space 11 will drive the positive ions and negative ions in the first installation space 11 to flow to the designated area, and the air flowing through the second installation space 12 will drive the air negative ions in the second installation space 12 to flow to the designated area, so as to disinfect the air in the designated area.

[0141] According to the air conditioner 5 of the embodiment of the present invention, by utilizing the disinfection device 1 according to the above-mentioned embodiment of the present invention, both the plasma generator 20 and the negative ion generator 30 can be used for sterilization, so that it is convenient to enrich the sterilization function of the disinfection device 1 and to achieve a better publicity effect. At the same time, the shell 10 is used to separate the first discharge part 210 and the second discharge part 310 to avoid mutual influence between the plasma generator 20 and the negative ion generator 30, so as to ensure the sterilization effect of the disinfection device 1.

[0142] In some embodiments of the present invention, Fig.10 As shown, the air conditioner body 50 includes a plurality of air guide blades 53, and the plurality of air guide blades 53 are swingably arranged in the air outlet channel 51. The plurality of air guide blades 53 are spaced apart along the length direction of the cross section of the air outlet channel 51 to control the air outlet direction of the air outlet channel 51, and further control the flow direction of the air in the air outlet channel 51, so as to transport the air in the air outlet channel 51 to a designated area according to demand.

[0143] Among them, the disinfection device 1 is arranged between at least two adjacent guide blades 53, so as to ensure that when the guide blades 53 change the flow direction of the air in the air outlet channel 51, the air in the air outlet channel 51 will flow through the first installation space 11 and the second installation space 12, and then the ions in the first installation space 11 and the second installation space 12 can be transported to the designated area, so as to use the ions generated by the disinfection device 1 to sterilize the air in the designated area.

[0144] The distance between the second discharge section 310 and the adjacent air guide vane 53 is 20 mm to 30 mm to ensure the distance between the second discharge section 310 and the air guide vane 53. If the distance between the second discharge section 310 and the air guide vane 53 is too far, it cannot be guaranteed that the air can flow smoothly through the first installation space 11 and the second installation space 12. If the distance between the second discharge section 310 and the air guide vane 53 is too close, the negative air ions generated at the second discharge section 310 will adhere to the air guide vane 53, affecting the disinfection efficiency of the disinfection device 1.

[0145] Therefore, the distance between the second discharge section 310 and the adjacent air guide vane 53 is 20 mm to 30 mm, so that the positive ions and negative ions in the first installation space 11 can flow to the designated area with the air, and the air negative ions in the second installation space 12 can flow to the designated area with the air, thereby preventing the air negative ions in the second installation space 12 from accumulating on the air guide vane 53.

[0146] Optionally, the distance between the second discharging portion 310 and the adjacent wind guide vane 53 is 20 mm, 22 mm, 24 mm, 25 mm, 26 mm, 28 mm or 30 mm.

[0147] In some embodiments of the present invention, Fig.12As shown, the air conditioner body 50 includes an air guide plate 54, which is rotatably disposed at the air outlet 52 to open or close at least a portion of the air outlet 52, wherein when the air guide plate 54 opens the air outlet 52, a distance M between the air guide plate 54 and the disinfection device 1 is greater than 50 mm. When the disinfection device 1 generates ions to sterilize the air, the disinfection device 1 generates ions in the first installation space 11 and the second installation space 12, so that the air guide plate 54 and the disinfection device 1 maintain a certain distance, so as to prevent the ions in the first installation space 11 and the second installation space 12 from adhering to the air guide plate 54 when the ions flow to the designated area with the air, thereby affecting the disinfection efficiency of the disinfection device 1.

[0148] Optionally, the distance M between the air guide plate 54 and the disinfection device 1 is 50 mm, 55 mm, 60 mm, 65 mm, 70 mm, 75 mm, 80 mm, 85 mm, 90 mm, 95 mm, or 100 mm.

[0149] In some embodiments of the present invention, the wall of the air outlet channel 51 includes an installation wall 511, and the installation wall 511 is provided with an installation hole. The disinfection device 1 cooperates with the installation hole to set the disinfection device 1 in the air outlet channel 51, so that the disinfection device 1 can disinfect the air in the air outlet channel. At the same time, when the air flows in the air outlet channel 51, the ions generated in the disinfection device 1 will flow to the designated area with the air, so as to be able to sterilize or reduce dust in the designated area.

[0150] In some optional embodiments of the present invention, Fig.13 As shown, the second installation space 12 is located outside the shell 10, and the distance L between the surface where the second discharge part 310 in the second installation space 12 is located and the inner surface of the installation wall 511 is 1mm to 5mm. If the distance L between the surface where the second discharge part 310 in the second installation space 12 is located and the inner surface of the installation wall 511 is too small, the ions generated by the second discharge part 310 will adhere to the installation wall 511. If the distance L between the surface where the second discharge part 310 in the second installation space 12 is located and the inner surface of the installation wall 511 is too large, the height of the shell 10 will be too high, which is not conducive to the installation and disassembly of the disinfection device 1.

[0151] Therefore, the distance L between the surface where the second discharge part 310 is located in the second installation space 12 and the inner surface of the installation wall 511 is 1 mm to 5 mm, so that a certain distance is maintained between the second installation space 12 and the inner surface of the installation wall 511, so that the ions generated by the second discharge part 310 can smoothly reach the designated area with the air, thereby ensuring the disinfection efficiency of the disinfection device 1.

[0152] like Fig.13As shown, in this embodiment, the distance L between the bottom wall of the second installation space 12 and the inner bottom wall of the installation wall 511 is 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm or 5 mm.

[0153] In some optional embodiments of the present invention, a card slot 143 is provided in one of the shell 10 and the hole wall of the mounting hole, and a card connection portion is provided in the other of the shell 10 and the hole wall of the mounting hole. The card slot 143 is engaged with the card connection portion to set the shell 10 in the mounting hole, and then set the disinfection device 1 in the air outlet channel 51.

[0154] In some specific embodiments of the present invention, the side wall of the shell 10 is provided with a first protrusion 141 and a second protrusion 142 arranged in the height direction thereof, a card slot 143 is defined between the first protrusion 141 and the second protrusion 142, and a clamping portion is provided on the hole wall of the mounting hole. When the disinfection device 1 is set in the air outlet channel 51, the disinfection device 1 is passed through the mounting hole so that the card slot 143 cooperates with the clamping portion of the hole wall of the mounting hole to fix the disinfection device 1 in the air outlet channel 51.

[0155] Among them, one of the first protrusion 141 and the second protrusion 142 close to the air outlet channel 51 has a guide surface 145, and the guide surface 145 extends from the outside of the air outlet channel 51 to the inside in the direction close to the side wall of the shell 10, so that when the shell 10 passes through the mounting hole, the guide surface 145 is used to guide the moving direction of the shell 10, thereby achieving smooth cooperation between the shell 10 and the mounting hole, so that the card slot 143 on the shell 10 can be smoothly cooperated with the card connection part of the hole wall of the mounting hole.

[0156] like Figure 4 As shown, in the present embodiment, the height direction of the shell 10 extends in the up-down direction. It should be understood here that the above-mentioned direction limitation is only for the convenience of describing the accompanying drawings, and will not limit the actual setting position and direction of the disinfection device 1. The first protrusion 141 and the second protrusion 142 are arranged at intervals in the up-down direction, and the first protrusion 141 is arranged above the second protrusion 142. The first protrusion 141 is provided with a guide surface 145. When the shell 10 is installed in the mounting hole, the shell 10 should be moved from bottom to top so that the guide surface 145 on the first protrusion 141 cooperates with the inner wall of the mounting hole, thereby guiding the moving direction of the shell 10 so that the shell 10 can smoothly cooperate with the mounting hole.

[0157] Among them, the guide surface 145 extends from bottom to top toward the direction close to the side wall of the shell 10, that is, when the shell 10 is installed in the mounting hole, the upper end of the guide surface 145 first cooperates with the inner wall of the mounting hole, and when the shell 10 is moved, the clamping portion of the inner wall of the mounting hole has an extrusion force on the guide surface 145 toward the side wall of the shell 10, so that the first protrusion 141 can be deformed, and then the shell 10 can be smoothly moved from bottom to top. When the shell 10 is moved to a specified position, the clamping portion of the mounting hole cooperates with the clamping groove 143 below the first protrusion 141 to fix the position of the shell 10, so that the shell 10 can be fixed in the air outlet channel 51.
