[0021] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort.

[0022] Please refer to Figures 1-3 As shown, this utility model provides a plasma air sterilizer. A first battery 16 is provided at the upper end of the housing 1, and a plasma emitter 17 is connected to the lower end of the first battery 16. The first battery 16 can provide power to the plasma emitter 17 and the control panel 25. Under the action of electrical energy, the plasma emitter 17 excites plasma for air purification and sterilization.

[0023] The first battery 16 is also connected to a light source (not shown in the figure). The light source is located on the top surface inside the housing 1. The first battery 16 supplies power to the light source, and the light source shines onto the photocatalytic filter 6 to achieve the effect of photocatalytic sterilization and purification.

[0024] Ventilation ducts 18 are installed on both sides of the housing 1. A dust filter plate 19 is installed on the side of the ventilation duct 18 away from the housing 1. A pair of bolts 20 are installed on the dust filter plate 19, and a threaded hole 21 is opened on the ventilation duct 18 at the corresponding position. The threaded hole 21 cooperates with the bolt 20 to realize the detachable connection of the dust filter plate 19. The dust filter plate 19 can be reused and can be cleaned with water when it gets dirty.

[0025] When facing the control panel 25 of the enclosure 1, the ventilation duct 18 on the left side of the enclosure 1 is the air inlet, and the ventilation duct 18 on the right side is the air outlet. The ventilation duct 18 on the left side passes through the side of the enclosure 1 and is connected to a fan blade 24. The fan blade 24 is located inside the enclosure 1, and a drive device 23 is provided inside the fan blade 24. The drive device 23 is connected to the bottom surface of the enclosure 1 via a support rod. The output end of the drive device 23 is connected to the fan blade 24. The fan blade 24 and the drive device 23 cooperate to draw outside air into the enclosure 1 under the action of electrical energy; both are a type of exhaust fan. A second battery 22 is provided at the bottom of the enclosure 1, which can power the drive device 23.

[0026] The upper part of the housing 1 is equipped with a control panel 25, which is electrically connected to the drive unit 23, the first battery 16, the second battery 22, the plasma emitter 17, and the light source. It can display the power level and working status of the plasma air sterilizer, and can input commands to control the drive unit 23, the plasma emitter 17, and the light source to operate.

[0027] When in use, the drive unit 23 starts and drives the fan blades 24 to rotate. The rotation of the fan blades 24 causes the outside air to enter the box 1 through the ventilation pipe 18. At the same time, the plasma emitter 17 starts and generates plasma. The air is deodorized by passing through the activated carbon filter layer 5. The plasma ionizes odor molecules, bacteria, viruses and other substances in the air, achieving the effect of air purification and disinfection. The photocatalytic filter 6 further kills bacteria and viruses in the air and decomposes gases such as formaldehyde, benzene and ammonia. Finally, the disinfected and purified air is discharged through the ventilation pipe 18 on the right side.

[0028] As a further implementation of this embodiment, such as Figures 1-4 As shown, the housing 1 is equipped with two pairs of slide rails 2, which are distributed on both sides of the plasma emitter 17. A first frame 3 and a second frame 4 are slidably mounted within the two pairs of slide rails 2. An activated carbon filter layer 5 is mounted on the second frame 4, and a photocatalytic filter 6 is mounted on the first frame 3. The activated carbon filter layer 5 filters and adsorbs gases in the air, while the photocatalytic filter 6 exerts a high-intensity oxidation function to destroy bacterial cells, resulting in more thorough purification and disinfection. Limiting holes 7 are provided on both the first frame 3 and the second frame 4. A fixing plate 8 is fixedly connected to the bottom of the housing 1, and two baffles 9 are fixedly connected to the upper end of the fixing plate 8. Limiting rods 10 pass through each of the two baffles 9. A first connecting plate 11 and a second connecting plate 12 are fixedly connected to one end of each limiting rod 10. Springs 13 are fixedly connected between the first connecting plate 11, the second connecting plate 12, and the two baffles 9, respectively. A first magnet 14 is mounted on one side of the first connecting plate 11, and a second magnet 15 is mounted on one side of the second connecting plate 12.

[0029] Spring 13 is a tension spring, which tends to contract when no external force is applied, causing a portion of the limiting rod 10 to pass through the limiting hole 7. The first magnet 14 and the second magnet 15 have opposite polarities, and the magnetic force they exert upon attraction is greater than the combined elastic force of the two tension springs. When the first magnet 14 and the second magnet 15 attract each other, spring 13 is further stretched, and the first magnet 14 and the second magnet 15 will not separate without external force. When an external force is applied, the first magnet 14 and the second magnet 15 separate, and the limiting rod 10 contracts under the elastic force of the tension spring, thus inserting a portion of the limiting rod 10 into the limiting hole 7. When it is necessary to disassemble and replace the activated carbon filter layer 5 and the photocatalytic filter 6, the first connecting plate 11 and the second connecting plate 12 can be pulled at the same time, so that the first connecting plate 11 and the second connecting plate 12 drive the spring 13 to stretch. At the same time, the two limiting rods 10 leave the limiting hole 7 until the first magnet piece 14 on the first connecting plate 11 and the second magnet piece 15 on the second connecting plate 12 are attracted and fixed. At the same time, the first connecting plate 11 and the second connecting plate 12 are fixed by magnetic attraction. At this time, the first frame 3 and the second frame 4 are not restricted, so the first frame 3 and the second frame 4 can be quickly slid out from the slide rail 2. After the activated carbon filter layer 5 and photocatalytic filter 6 are replaced, they are placed behind the second frame 4 and the first frame 3. The two frames can quickly slide into the slide rail 2. At the same time, the first connecting plate 11 and the second connecting plate 12 are pulled, so that the first magnet 14 and the second magnet 15 on the first connecting plate 11 and the second connecting plate 12 are separated. Under the elastic force of the spring 13, the first connecting plate 11 and the second connecting plate 12 are moved in opposite directions, so that the two limiting rods 10 can be inserted into the limiting hole 7 again and the first frame 3 and the second frame 4 are fixed. The activated carbon filter layer 5 and the photocatalytic filter 6 can be easily disassembled and replaced through this device. It is very convenient to use and does not affect the air purification and disinfection effect.

[0030] Specific working principle: During use, the drive device 23 is started and drives the fan blades 24 to rotate. The rotation of the fan blades 24 causes the outside air to enter the chamber 1 through the ventilation pipe 18 on the left. At the same time, the plasma emitter 17 and the light source are activated. The air passes through the activated carbon filter layer 5, where odors and some large dust particles are adsorbed. Then, through the ionization effect of the plasma excited by the plasma emitter 17, the air is purified and disinfected. Then, through the photocatalytic filter 6, the high-intensity oxidation function destroys the cells of bacteria, making the purification and disinfection more thorough. Finally, the disinfected and purified air is discharged through the ventilation pipe 18 on the right. When it is necessary to disassemble and replace the activated carbon filter layer 5 and the photocatalytic filter 6, the first connecting plate 11 and the second connecting plate 12 can be pulled simultaneously. This causes the first connecting plate 11 and the second connecting plate 12 to stretch the spring 13, while the two limiting rods 10 move away from the limiting hole 7 until the first magnet 14 on the first connecting plate 11 and the second magnet 15 on the second connecting plate 12 are attracted and fixed together. At the same time, the first connecting plate 11 and the second connecting plate 12 are attracted and fixed together, thereby allowing the first frame 3 and the second frame 4 to be removed from the slide rail 2 and taken out. The unused first frame 3, which contains the activated carbon filter layer 5 and the photocatalytic filter 6, can then be removed from the slide rail 2. The second frame 4 and the first frame 3 slide into the slide rail 2, and at the same time pull the first connecting plate 11 and the second connecting plate 12, so that the first magnet 14 and the second magnet 15 on the first connecting plate 11 and the second connecting plate 12 are separated. Under the elastic force of the spring 13, the first connecting plate 11 and the second connecting plate 12 are driven to move in opposite directions, so that the two limiting rods 10 can be inserted into the limiting hole 7 again and the first frame 3 and the second frame 4 are fixed. With this device, the activated carbon filter layer 5 and the photocatalytic filter 6 can be easily disassembled and replaced. It is very convenient to use and does not affect the air purification and disinfection effect.
