[0002] With increasing public awareness of indoor air quality, air purifiers have become common household appliances. Among them, electrostatic air purifiers are widely used due to their advantages of requiring no consumables and high purification efficiency. However, most existing air purifiers rely solely on electrostatic adsorption modules, lacking primary filtration for large particles. This leads to rapid dust accumulation on the electrostatic plates, requiring frequent cleaning. Furthermore, the lack of a fine filtration module prevents effective interception of residual fine particles or odor molecules after electrostatic adsorption, resulting in limited purification effects. Therefore, we propose an electrostatic air purifier. Summary of the Invention

This invention solves the problems of most existing air purification devices relying solely on electrostatic adsorption modules, lacking primary filtration for large particulate impurities, leading to rapid dust accumulation on the electrostatic electrode plates and requiring frequent cleaning. Furthermore, the lack of a fine filtration module prevents effective interception of residual microparticles or odor molecules after electrostatic adsorption, resulting in limited purification effectiveness.

[0014] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0015] like Figure 1-4 As shown, this utility model is an electrostatic air purification device, including a housing 1. An mounting plate 2 is provided at the upper end of the housing 1. An air inlet 3 is provided on the side of the housing 1 below the mounting plate 2. A first fixing frame 4 is provided on one side of the air inlet 3.

A high-voltage generator 6 is provided below the mounting plate 2 on the housing 1. The high-voltage generator 6 has a negative electrode plate 7, which is a metal needle array plate. When the high-voltage generator 6 is working, negative charges can be released through the negative electrode plate 7. A positive electrode plate 8, which matches the negative electrode plate 7, is a metal plate, provided at the bottom of the housing 1. A high-voltage electrostatic field is formed between the negative electrode plate 7 and the positive electrode plate 8. When the airflow passes between the negative electrode plate 7 and the positive electrode plate 8, the particulate matter in the airflow is polarized and adsorbed. On the positive electrode plate 8, a partition 9 is provided below the side of the mounting plate 2 away from the high voltage generator 6. A fan 10 is provided on the side of the mounting plate 2 away from the high voltage generator 6. A guide groove 11 is provided at the air inlet of the fan 10.

A second fixing frame 13 is provided in the installation groove 12. An activated carbon filter 14 is provided in the second fixing frame 13. When the airflow passes through the activated carbon filter 14, the activated carbon filter 14 can effectively adsorb harmful gases and odors in the airflow. An air outlet 15 is provided at the upper end of the side of the housing 1 away from the air inlet window 3. When the fan 10 is working, the fan 10 drives the airflow, so that the airflow can enter the interior of the housing 1 through the air inlet window 3.

[0020] Each of the four corners of the housing 1 is equipped with a brake caster 24, which makes it easier to move and position the purification device.
[0021] Specifically, in this utility model, the positioning block 17 can be inserted into the positioning hole 18, and the limiting block 19 can limit the first fixed frame 4 and the second fixed frame 13. Through the cooperation between the positioning block 17 and the positioning hole 18, the installation stability of the first fixed frame 4 and the second fixed frame 13 is effectively guaranteed. The shear groove 20 allows the positioning block 17 to deform when the limiting block 19 is pressed, thereby making it easier to install and disassemble the positioning block 17 with the first fixed frame 4 and the second fixed frame 13. When the fan 10 is working... At this time, the fan 10 drives the airflow, allowing the airflow to enter the housing 1 through the air inlet window 3. When the airflow passes through the filter screen 5, the filter screen 5 can filter the solid impurities in the airflow. When the airflow passes between the negative electrode plate 7 and the positive electrode plate 8, the particulate matter in the airflow will be polarized and adsorbed on the positive electrode plate 8. When the airflow passes through the activated carbon filter screen 14, the activated carbon filter screen 14 can effectively adsorb harmful gases and odors in the airflow. The door 22 is movably connected to the housing 1 by a pin, and the setting of the door 22 makes it easier for staff to clean the inside of the purification device.
