Description

Technical Field

[0001] This utility model belongs to the field of air sterilizer technology, specifically a plasma air sterilizer. Background Technology

[0002] As people's demands for indoor air quality continue to increase, air purifiers, as key devices for improving and maintaining a healthy environment, are also undergoing continuous design and technological advancements. Traditional air purifiers primarily remove particulate matter, harmful gases, and microorganisms from the air through a series of filters and various disinfection technologies.

[0003] In existing technologies, many air purifiers lack effective means to monitor the filter status in real time. This often forces users to rely solely on the manufacturer's approximate usage time recommendations to determine whether the filter needs replacement, ignoring the impact of actual usage conditions (such as pollution levels and operating frequency) on filter lifespan. This can result in premature replacement leading to resource waste, or delayed replacement affecting purification efficiency and machine performance. This invention provides a plasma air purifier that allows real-time monitoring of the filter's operating status, thereby determining when timely filter replacement is necessary.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] Reference Figure 1-5 As shown, a plasma air sterilizer includes a cabinet 1. A hinged door 2 is connected to the front end of the cabinet 1. An air pump 3 is installed on the outer periphery of the bottom of the cabinet 1, and an air outlet 4 is opened on the outer periphery of the top of the cabinet 1. A filter frame 5 is installed inside the cabinet 1 above the air pump 3. An installation assembly is also installed inside the cabinet 1 above the air pump 3. The installation assembly includes a drive motor 6, a conveyor belt 7, and an installation platform 8. The installation platform 8 is located on the front and rear inner walls of the cabinet 1. Both the drive motor 6 and the conveyor belt 7 are mounted on the installation platform 8. The output end of the drive motor 6 is rotatably connected to a drive roller inside the conveyor belt 7. A flow equalization membrane assembly 9 is installed inside the cabinet 1 above the installation platform 8. Differential pressure sensors 10 are installed on the two side walls of the flow equalization membrane assembly 9 inside the cabinet 1. The installation platform 8 is only located on the front and rear inner walls of the cabinet 1, leaving the middle of the cabinet 1 hollow, which does not affect the subsequent installation of the filter frame 5 or the subsequent airflow.

[0023] Furthermore, an installation port 11 is provided on the right side of the cabinet 1 at the same horizontal level as the conveyor belt 7. The filter frame 5 can be slidably mounted on the conveyor belt 7 through the installation port 11. An opening and closing device for closing the installation port 11 is provided on the inner wall of the cabinet 1 above the installation port 11. The opening and closing device includes a servo motor 12 and a closing plate 13. A fixing plate 14 is fixedly provided on the inner wall of the cabinet 1 above the installation port 11. The servo motor 12 is fixedly mounted on the fixing plate 14. The closing plate 13 is in contact with the inner wall of the cabinet 1. A first sliding groove 15 is vertically provided on the inner wall of the cabinet 1. A sliding block 16 is provided on the side of the closing plate 13 near the cabinet 1. A rack 1301 is provided on the side of the closing plate 13 away from the cabinet 1. The sliding block 16 is slidably mounted in the first sliding groove 15. A transmission gear is provided at the output end of the servo motor 12. The servo motor 12 is meshed with the rack 1301 on one side of the closing plate 13 through the transmission gear.

[0024] Furthermore, a groove 17 is provided below the mounting opening 11, and the bottom end of the closing plate 13 can be engaged in the groove 17. The engagement of the bottom end of the closing plate 13 in the groove 17 can make the cabinet 1 sealed, preventing internal gas leakage.

[0025] Furthermore, several sets of ion tube assemblies 18 are installed inside the cabinet 1 above the flow equalization membrane assembly 9. The ion tube assemblies 18 sterilize the gas passing through the filter frame 5.

[0026] Furthermore, a one-way valve 19 is installed at the end of the air pump 3 that extends into the cabinet 1. The one-way valve 19 can prevent gas backflow, which can increase the safety of the equipment and reduce energy loss.

[0027] Furthermore, an exhaust fan 20 is installed inside the cabinet 1 at a position corresponding to the air outlet 4. The exhaust fan 20 can guide the disinfected gas out of the cabinet 1 through the air outlet 4.

[0028] Furthermore, a control panel 21 is provided on the door 2. The control panel 21 is equipped with buttons that can control the drive motor 6 and the servo motor 12. At the same time, the differential pressure sensor 10 can transmit signals to the control panel 21 for the operator to view in real time.

[0029] In this embodiment of the utility model, please refer to Figure 1-4The working principle is as follows: The operator first turns on the air pump 3 at the bottom of the cabinet 1. The air pump 3 can draw external air into the cabinet 1 for disinfection. One-way valve 19 is installed at the end of the air pump 3 that extends into the cabinet 1 to prevent gas backflow. After the gas enters the cabinet 1, it first passes through the filter frame 5 on the conveyor belt 7. The filter frame 5 is equipped with a filter that can adsorb and filter out dust. The filtered gas will pass through the flow equalization membrane assembly 9, and finally pass through the ion tube assembly 18 above the flow equalization membrane assembly 9 for disinfection. After being guided by the exhaust fan 20 on the cabinet 1, it will be discharged from the cabinet 1.

[0030] Please see Figure 1-5 A differential pressure sensor 10 is installed above the flow equalization membrane assembly 9. When the differential pressure sensor 10 detects a significant decrease in the airflow velocity and flow rate through the flow equalization membrane, it sends a signal to the control panel 21 on the switch door 2. This indicates that the filter screen inside the filter frame 5 has accumulated a large amount of dust and needs to be replaced. At this time, simply start the servo motor 12 installed on the fixed plate 14. The gear at the output end of the servo motor 12 engages and drives the closing plate 13 to move upward from the groove 17 at the bottom of the mounting port 11. Then, start the drive motor 6. The output end of the drive motor 6 drives the drive roller in the conveyor belt 7 to rotate. The conveyor belt 7 then moves the filter frame 5 outward through the mounting port 11. The operator can then clean and replace the filter screen inside the filter frame 5. After replacement, simply insert one end of the filter frame 5 into the mounting port 11, then turn on the drive motor 6 and use the conveyor belt 7 to place the filter frame 5 inside the cabinet 1. Next, start the servo motor 12 to re-lock the closing plate 13 into the groove 17 of the mounting port 11, so that the cabinet 1 is sealed again. This completes the entire replacement process.
