Description

Technical Field

[0001] This utility model relates to the field of air sterilizer technology, and in particular to a plasma air sterilizer. Background Technology

[0002] Plasma air purifiers are devices that use plasma technology to purify and sterilize the air. They are widely used in homes, hospitals, laboratories, and other environments requiring highly clean air. By generating high concentrations of positive and negative ions, plasma air purifiers effectively remove bacteria, viruses, allergens, and various fine particulate matter from the air, providing a fresher and healthier indoor air environment.

[0003] However, traditional plasma air sterilizers have significant design flaws, primarily in that their air inlets are typically located at the top of the machine, while the air outlets are at the bottom. This layout prevents effective air circulation, severely limiting the sterilization area and effectiveness, and making it difficult to evenly distribute the treated clean air throughout the room, thus affecting overall air purification efficiency. Utility Model Content

[0004] This application provides a plasma air sterilizer that solves the technical problem that the layout of the air inlet and outlet of the plasma air sterilizer in the prior art leads to the inability to effectively circulate indoor air.

[0005] This application provides a plasma air sterilizer, characterized in that it includes:

[0006] chassis;

[0007] An air inlet is located at the bottom of the housing.

[0014] In some embodiments, the plasma air sterilizer further includes a second partition, which is perpendicular to the air inlet and air outlet. The second partition divides the interior of the casing into a control chamber and an air guide chamber. The plasma generator, the cross-flow fan, and the first partition are all located in the air guide chamber. The control chamber is equipped with a controller and a display screen. The motor of the cross-flow fan is located in the control chamber. The display screen is embedded in the casing. The motor of the cross-flow fan, the plasma generator, and the display screen are all electrically connected to the controller.

[0015] In some embodiments, a baffle is fixedly disposed inside the housing, and the baffle is installed at the air inlet.

[0016] In some embodiments, the baffle includes a frame and a plurality of baffles. The frame is arranged around the outer ring of the air inlet, and the baffles are arranged in a plurality of spaced intervals along the long side of the frame. The baffles on the two long sides of the frame are inclined toward the center of the plasma generator.

[0017] In some embodiments, the spoilers on the two long sides of the frame are staggered.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0031] This application provides a plasma air sterilizer, which solves the technical problem in the prior art where the layout of the air inlet and outlet of the plasma air sterilizer leads to ineffective circulation of indoor air.

[0032] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0033] like Figures 1-3 As shown, this application provides a plasma air sterilizer, characterized in that it includes a housing 10, an air inlet 11, an air outlet 12, and a plasma generator 13. The air inlet 11 is located below the housing 10 to ensure that untreated air can be drawn in from a lower position in the room, which helps to capture dust and pollutants near the ground. The air outlet 12 is located above the housing 10 and is inclined. The plasma generator 13 is installed inside the housing 10.

[0034] The bottom air inlet 11 draws in air from a lower position, which is then subjected to efficient sterilization and purification by the plasma generator 13. The clean air is then discharged through the inclined air outlet 12, forming a forced air circulation that allows the air in the room to be fully mixed and purified, increasing the disinfection area.

[0035] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0036] Specifically, the air outlet 12 has an inclination angle ranging from 10° to 55°, allowing the device to draw in unpurified air from the bottom of the room. After sterilization by the built-in plasma generator 13, the purified air is discharged obliquely upwards at a certain angle. By adjusting the angle of the air outlet 12, the diffusion direction and range of clean air can be effectively controlled, thereby forcing the circulation of indoor air and ensuring a uniform improvement in air quality throughout the space.

[0037] Preferably, the air outlet 12 is tilted at a 45° angle. The treated clean air is discharged through the air outlet 12, which is located above the housing 10 and tilted at a 45° angle, ensuring that the purified air is effectively dispersed throughout the room, covering a wider range and improving the overall air quality of the space.

[0038] Preferably, a filter 14 is installed in the air inlet 11. When the equipment is running, the unpurified air first enters the machine through the air inlet 11 at the bottom. Large particulate pollutants in the air, such as dust and hair, are initially filtered by the filter 14 built into the air inlet 11, reducing the burden on the subsequent plasma generator 13. This not only improves the air purification efficiency but also extends the service life of the plasma generator 13.

[0039] After the filter 14 is embedded in the air inlet 11, it is locked by a locking block to prevent the filter 14 from falling off.

[0040] Preferred, such as Figure 2 , Figure 3 As shown, a first partition 15 is sealed and fixed inside the housing 10. The first partition 15 is arranged parallel to the air inlet 11 and the air outlet 12. The plasma generator 13 is located between the air inlet 11 and the first partition 15. The first partition 15 is provided with a through hole 151 corresponding to the outlet position of the plasma generator 13.

[0041] Air enters through the bottom air inlet 11 and is initially filtered by the filter 14 before being guided to the plasma generator 13 for sterilization. The treated air then flows through the through-hole 151 on the first partition 15 to the air outlet 12. The first partition 15 not only isolates and guides the airflow but also enhances the overall structural stability of the equipment. The through-hole 151 is precisely aligned with the outlet of the plasma generator 13, ensuring that all the clean air treated by the plasma generator 13 is blown to the air outlet 12, thus avoiding energy waste.

[0042] Furthermore, such as Figure 2 , Figure 3 As shown, the plasma air sterilizer also includes a cross-flow fan 16, which is installed inside the housing 10. The cross-flow fan 16 is located between the air outlet 12 and the first partition 15, and is arranged along the length of the air inlet 11.

[0043] Unpurified air first enters through the bottom air inlet 11 and is initially filtered by the filter screen 14. It is then guided to the plasma generator 13 for sterilization. The treated clean air passes through the through holes 151 on the first partition 15 and is powered by the cross-flow fan 16, ensuring that the air can circulate evenly and efficiently throughout the room, while also improving the overall efficiency of air purification.

[0044] Furthermore, such as Figure 2 , Figure 3As shown, the plasma air sterilizer also includes a second partition 17, which is perpendicular to the air inlet 11 and the air outlet 12. The second partition 17 divides the interior of the housing 10 into a control chamber 101 and an air guide chamber 102. The plasma generator 13, the cross-flow fan 16, and the first partition 15 are all located in the air guide chamber 102. The control chamber 101 is equipped with a controller 18 and a display screen 19. The motor of the cross-flow fan 16 is located in the control chamber 101. The display screen 19 is embedded in the housing 10 for easy operation and monitoring by the user. The motor of the cross-flow fan 16, the plasma generator 13, and the display screen 19 are all electrically connected to the controller 18.

[0045] Unpurified air enters through the bottom air inlet 11 and is initially filtered by the filter 14. It is then guided to the plasma generator 13 for sterilization within the air guide chamber 102. The treated air is accelerated by the cross-flow fan 16 and discharged through the 45° angled air outlet 12. The controller 18 coordinates the operation of the motor of the cross-flow fan 16, the plasma generator 13, and the display screen 19, ensuring efficient and stable operation of the entire purification process. The design of the first partition 15 and the second partition 17 not only optimizes the internal space utilization of the equipment but also effectively separates the electrical control system from the air purification system, reducing electromagnetic interference and improving the reliability and safety of the equipment. The motor of the cross-flow fan 16 is located inside the control room 101, keeping it away from high humidity environments and extending its lifespan. Furthermore, users can intuitively view the equipment's operating status through the display screen 19 and adjust settings as needed. All operations are centrally managed by the controller 18, ensuring coordinated operation of all components. Combined with the easily replaceable front-pull filter 14, users can conveniently and quickly complete daily maintenance without disassembling the entire machine.

[0046] Preferred, such as Figures 2-5 As shown, a spoiler 20 is fixedly installed inside the housing 10. The spoiler 20 is installed at the air inlet 11 to optimize the airflow path.

[0047] Specifically, the spoiler 20 includes a frame 201 and multiple spoiler plates 202. The frame 201 is arranged around the outer ring of the air inlet 11. Multiple spoiler plates 202 are spaced apart on the long side of the frame 201. The spoiler plates 202 on the two long sides of the frame 201 are inclined towards the middle of the plasma generator 13. There is a gap between the spoiler plates 20 on both sides of the frame 201 to ensure that the gap in the middle does not affect the airflow.

[0048] Furthermore, the spoilers 202 on the two long sides of the frame 201 are staggered.

[0049] When unpurified air enters through the bottom air inlet 11, it first encounters the baffle 20. The baffle 202 divides and guides the straight-in airflow, effectively dispersing and redirecting the incoming air, avoiding laminar flow, and ensuring that the air can fully contact the plasma generator 13. This increases the contact time and area between the air and the plasma sterilizer, thereby improving the sterilization effect.

[0050] Preferred, such as Figure 2 , Figure 3 As shown, a guide plate 21 is fixedly installed inside the housing 10. The guide plate 21 is installed at the air outlet 12. The guide plate 21 has an arc-shaped guide surface. The cross-section of one end of the guide surface is vertically downward and corresponds to the outlet of the plasma generator 13. The cross-section of the other end of the guide surface is horizontal and corresponds to the air outlet 12.

[0051] The clean air processed by the plasma generator 13 first enters the air guide chamber 102 through the through hole 151 on the first partition 15, and is then guided to the guide plate 21 by the cross-flow fan 16. The arc design of the guide plate 21 makes the air flow smoother and more uniform, which can effectively reduce air turbulence and resistance. One end of the plate has a vertical downward cut corresponding to the outlet of the plasma generator 13, ensuring that the purified air can be efficiently collected and guided; the other end has a horizontal cut corresponding to the air outlet 12, ensuring that the air is discharged from the 45° inclined air outlet 12 at the optimal angle and speed, so that the air smoothly transitions from the outlet of the plasma generator 13 to the air outlet 12, improving the air circulation efficiency and achieving effective circulation and uniform distribution of indoor air.
