[0050] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0051] Reference will be made below Figures 1 - 12 to describe the disinfection device 100 according to the first aspect embodiment of the present utility model.

[0052] As Figures 1 - 7 shown, the disinfection device 100 according to the first aspect embodiment of the present utility model includes: a seat body 10, a cover body 20, a negative ion generator 30, and a plasma generator 40.

[0053] A first cavity 101 is defined inside the seat body 10; the cover body 20 is covered on the seat body 10, and the seat body 10 and the cover body 20 cooperate to define a second cavity 102; the negative ion generator 30 is disposed inside the first cavity 101 and has a first discharge portion 31 extending to the outside of the first cavity 101; the plasma generator 40 is disposed inside the second cavity 102 and has a second discharge portion 41 located inside the second cavity 102.

[0054] For example, the cover 20 is disposed above the base 10. Further, the connection between the cover 20 and the base 10 can be a snap connection. The negative ion generator 30 is disposed in the first cavity 101. After the negative ion generator 30 is powered on, the first discharge part 31 can generate a 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. The plasma generator 40 is disposed in the second cavity 102. After the plasma generator 40 is powered on, the second discharge part 41 can generate a strong electric field, and the generated strong electric field ionizes the air around the second discharge part 41, thereby generating positive ions and negative ions.

[0055] It should be noted that after the air negative ions generated by the first discharge part 31 of the negative ion generator 30 meet and combine with bacteria, they can change the structure of the bacteria or transfer the energy of the bacteria, thereby being able to eliminate the bacteria. In addition, the negatively charged air negative ions can perform electrode neutralization with the positively charged smoke, dust and other particles floating in the air, so that the smoke, dust and other particles are naturally deposited, thus facilitating the improvement of air quality.

[0056] It should be noted that the positive ions and negative ions generated by the second discharge part 41 of the plasma generator 40 can generate huge energy at the moment of positive and negative charge neutralization in the air, resulting in a change in the structure of the surrounding bacteria and causing the surrounding bacteria to die, thereby achieving a bactericidal effect. In addition, the number of negative ions generated by the ionization of the air around the second discharge part 41 is greater than the number of positive ions. The negative ions remaining after the neutralization of the positive ions and negative ions can float in the air. The negative ions floating in the air will combine with the soot and dust particles in the air, making the soot and dust particles charged. Due to the electrostatic effect, the charged soot and dust particles are attracted to the ground and settle to the ground, thus facilitating the improvement of air quality.

[0057] In this embodiment, when the negative ion generator 30 is powered on, the air negative ions generated by the first discharge part 31 of the negative ion generator 30 can effectively sterilize and remove dust from the air near the first discharge part 31. When the plasma generator 40 is powered on, the positive and negative charge neutralization of the positive ions and negative ions generated by the second discharge part 41 of the plasma generator 40 can perform a bactericidal treatment on the air around the second discharge part 41. In addition, the negative ions generated by the second discharge part 41 can also effectively remove dust from the air. Thus, the negative ion generator 30 and the plasma generator 40 can effectively improve the purification efficiency of the disinfection device 100. In addition, the first discharge part 31 and the second discharge part 41 are separated from each other, so as to effectively prevent the air negative ions generated by the first discharge part 31 from meeting the positive ions and negative ions generated by the second discharge part 41, thereby effectively ensuring the bactericidal effect of the disinfection device 100.

[0058] The disinfection device 100 according to an embodiment of the present utility model, by arranging a base body 10, a cover body 20, a negative ion generator 30 and a plasma generator 40 in the disinfection device 100, a first cavity 101 is defined in the base body 10, the cover body 20 is covered on the base body 10, the base body 10 and the cover body 20 cooperate to define a second cavity 102, the negative ion generator 30 is arranged in the first cavity 101 and has a first discharge part 31 extending to the outside of the first cavity 101, the plasma generator 40 is arranged in the second cavity 102 and has a second discharge part 41 located in the second cavity 102, which can effectively isolate the negative ions generated by the first discharge part 31 from the plasma generated by the second discharge part 41, reduce the interference between the plasma and the negative ions, and thus effectively improve the air purification efficiency.

[0059] In an embodiment of the present utility model, as Figure 6 and Figure 7 shown, the number of the first cavities 101 is multiple and they are respectively arranged on both sides of the cover body 20 in the first direction (for example Figure 6 and Figure 7 shown in the left - right direction), and the number of the negative ion generators 30 corresponds to that of the first cavities 101 one by one. For example, the number of the first cavities 101 can be two, three, four, five, six or more, and the multiple first cavities 101 are respectively arranged on both sides of the cover body 20 in the first direction. In a specific example, the number of the first cavities 101 is two and the two first cavities 101 are arranged symmetrically left and right.

[0060] Wherein, for the convenience of description, it is set that the length direction of the disinfection device 100 is the first direction, the height direction of the disinfection device 100 is the second direction, the width direction of the disinfection device 100 is the third direction, and the first direction, the second direction and the third direction intersect pairwise. In a specific example, the first direction, the second direction and the third direction are pairwise perpendicular to each other, the first direction is the left - right direction, the second direction is the up - down direction, and the third direction is the front - back direction.

[0061] In this embodiment, by setting the number of the first cavities 101 to be multiple and the multiple first cavities 101 are respectively arranged on both sides of the cover body 20 in the first direction, and the number of the negative ion generators 30 corresponds to that of the first cavities 101 one by one, the number of the air negative ions generated by the negative ion generator 30 can be effectively increased, thereby effectively improving the air purification effect and effectively expanding the range of the purification area.

An opening is formed on the seat cover 12, which passes through the seat cover 12 and is opposite to the open side of the second cavity 102.

[0065] In this embodiment, a base 11 is provided in the base body 10, and the base 11 defines a first cavity 101 and a second cavity 102 which are arranged at intervals and are open on one side in the second direction, thereby providing a reliable installation space for the negative ion generator 30 and the plasma generator 40; by providing a seat cover 12 on one side of the base 11 in the up and down direction, and covering the first cavity 101, and forming an opening on the seat cover 12 which passes through the seat cover 12 and is opposite to the open side of the second cavity 102, the cover body 20 is provided on the side of the seat cover 12 away from the base 11 in the second direction, and the opening cover is provided inside, thereby effectively isolating the first cavity 101 and the second cavity 102, and allowing air to smoothly enter the second cavity 102, so that the second discharge part 41 of the plasma generator 40 can ionize the surrounding air to generate positive ions and negative ions.

[0066] In one embodiment of the present invention, Figure 6 and Figure 7 As shown, the seat body 10 is provided with an isolation structure, the first cavity 101 and the second cavity 102 are respectively located on both sides of the isolation structure in the first direction, and the isolation structure includes at least one partition, which is arranged on one of the base 11 and the seat cover 12 and extends toward the other along the second direction.

[0068] In this embodiment, by providing an isolation structure in the seat body 10, and the first chamber 101 and the second chamber 102 are respectively located on both sides of the isolation structure in the first direction, it can effectively avoid the interference between the negative ion generator 30 and the plasma generator 40 during operation, thereby effectively ensuring that the negative ion generator 30 and the plasma generator 40 can give full play to their respective advantages; by providing at least one partition in the isolation structure, the partition is provided on one of the base 11 and the seat cover 12 and extends towards the other along the second direction, it can effectively ensure the isolation effect, and at the same time can effectively simplify the structure of the isolation structure, thereby effectively reducing the cost.

For example, the number of partitions can be two, three, four, five, six or more, and the plurality of partitions can form a continuous isolation layer, thereby forming a more effective isolation barrier.

[0070] In a specific example, for example Figure 6 and Figure 7 shown, the isolation structure includes two partitions, the two partitions are respectively a first partition 121 and a second partition 112, and the first partition 121 and the second partition 112 are arranged at intervals in the left-right direction.

[0074] In this embodiment, the side walls on both sides of the cover body 20 in the third direction are respectively set as a windward grille 21 and an air supply grille 22, wherein the disinfection device 100 is suitable for being arranged in the air outlet duct 501, and the third direction is the air flow direction in the air outlet duct 501, so that the air flow can flow in from the windward grille 21 and flow out from the air supply grille 22, thereby effectively carrying away the positive ions and negative ions generated by the plasma generator 40 to other areas for sterilization and dust removal.

[0075] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the cover body 20 is open at both ends in the first direction and is in a U-shape that opens toward the base 11. For example, the cover body 20 is open at both ends in the left-right direction, so that air can freely enter and exit the second cavity 102 from both ends of the cover body 20 in the first direction, thereby facilitating the circulation of airflow. For example, the projection of the cover body 20 in the left-right direction is U-shaped, so that a semi-enclosed space can be formed, thereby effectively enclosing the base 10 and the plasma generator 40.

[0076] In this embodiment, the cover body 20 is opened at both ends in the first direction, and the cover body 20 is in a U shape opening toward the base 11 , so as to effectively improve the flow of airflow and effectively cover the base 10 and the plasma generator 40 in the cover body 20 .

The first positive electrode part 42 is arranged below the first negative electrode part 43, and the second discharge part 41 is arranged on the first positive electrode part 42 and faces the first negative electrode part 43. In this way, a stable electric field can be formed around the second discharge part 41 when the plasma generator 40 works. When the plasma generator 40 is powered on, positive ions and negative ions can be generated in the second discharge part 41 between the first positive electrode part 42 and the first negative electrode part 43. The positive ions and negative ions can flow out of the second cavity 102 and diffuse to other areas under the action of the air flow.

In a specific example, for example Figure 6 and Figure 7 shown, the first positive electrode part 42 can be a rectangular plate-like structure, and the corners of the peripheral side of the first positive electrode part 42 are transitioned by arcs. The second discharge part 41 is arranged on the upper side edge of the first positive electrode part 42.

[0083] In this embodiment, by setting the first positive electrode part 42 as a plate-like structure, the second discharge part 41 is arranged on the peripheral side of the first positive electrode part 42, and the corners of the peripheral side of the first positive electrode part 42 are transitioned by arcs. It can not only effectively increase the contact area between the first positive electrode part 42 and the air, thereby effectively improving the efficiency of positive ions and negative ions generated by the second discharge part 41 ionizing the air, but also effectively avoid the accumulation of ions, thereby effectively improving the air purification effect.

The multiple escape holes 430 correspond to the multiple second discharge parts 41 one by one and are directly opposite in the second direction.

[0085] For example, the number of the second discharge parts 41 can be two, three, four, five, six or more, and the multiple second discharge parts 41 are arranged along the left-right direction. The first negative electrode part 43 is formed with multiple escape holes 430 penetrating through the first negative electrode part 43 along the up-down direction. The multiple escape holes 430 correspond to the multiple second discharge parts 41 one by one and are directly opposite in the up-down direction. Further, the distance L1 between the first positive electrode part 42 and the first negative electrode part 43 in the up-down direction is 4 mm - 8 mm.
