Description

Technical Field

[0001] This utility model belongs to the field of air purifier technology, and in particular relates to an ozone negative ion integrated formaldehyde removal device. Background Technology

[0002] With increasing public concern about indoor air quality, various air purification technologies have emerged. Among them, utilizing the strong oxidizing properties of ozone to decompose organic pollutants such as formaldehyde, and using negative ions to charge and agglomerate particulate matter for sedimentation, are two effective technical methods.

[0003] However, existing air purification equipment has some limitations in dealing with formaldehyde, and purifiers using a single technology often have limited effectiveness. Integrated units that simply combine ozone and negative ion functions often suffer from interference between the two technologies due to unreasonable structural layouts. This can lead to ozone inhibiting the generation of negative ions, or negative ions causing particulate matter to adhere to the ozone generator, affecting its efficiency. Furthermore, there are problems such as inconvenient component replacement, excessive wind resistance in the support structure leading to increased fan load, higher energy consumption, and louder noise. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an ozone negative ion integrated formaldehyde removal device that is compact in structure, highly efficient in purification, safe and reliable.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: it includes an outer shell, on the top of which a fan and a dust cover are installed, and a horizontally penetrating wind tunnel is provided on the outer shell. An annular air outlet cavity is installed inside the wind tunnel, and the annular air outlet cavity is connected to the fan through a flexible hose. Rubber feet are installed at the four corners of the bottom of the outer shell. A closed cover is installed at one end of the wind tunnel, and a negative ion output carbon brush rolled into a ring and tied tightly is provided inside the closed cover. A quartz ozone tube is also installed inside the wind tunnel.

[0006] Furthermore, the sealed hood seals one end of the wind tunnel outlet, causing the annular air outlet cavity to generate negative pressure when air is discharged, adsorbing negative ions and outputting negative ions generated by the carbon brush.

[0007] Furthermore, the quartz ozone tube is located downstream of the air outlet of the annular air outlet cavity, and the negative ion output carbon brush is located upstream of the annular air outlet cavity.

[0008] Furthermore, after the air forms a negative pressure, it first adsorbs negative ions, which then become charged and condense. These ions then flow through the quartz ozone tube and are deeply oxidized, avoiding mutual interference and forming a synergistic and orderly purification process.

[0009] Furthermore, the enclosed hood is connected to the outer shell and completely seals the port of the wind tunnel. Several wire clips are fixed on the inner wall of the enclosed hood, and the negative ion output carbon brush is rolled into a ring and inserted into several of the wire clips.

[0010] Furthermore, the high-voltage negative ion output carbon brush is completely sealed to effectively prevent the risk of electric shock to users. At the same time, the installation and replacement of the negative ion output carbon brush are made very simple by fixing it with a wire clamp.

[0011] Furthermore, the two sides of the quartz ozone tube are connected to the inner wall of the wind tunnel via a U-shaped bracket. The U-shaped bracket is installed in the middle section of the wind tunnel, and the volume of the central hole inside the U-shaped bracket is not less than 75% of the total volume of the bracket.

[0012] Furthermore, the highly transparent U-shaped support not only ensures stable support for the quartz ozone tube, but also greatly reduces airflow resistance, ensuring efficient airflow and purification, and reducing equipment operating noise.

[0013] Furthermore, the edge of the open port at the other end of the wind tunnel is designed with rounded corners. The main control module, power module, and negative ion generator are also installed inside the outer shell. The output end of the power module is electrically connected to the main control module. The main control module is electrically connected to the negative ion generator and the discharge electrode of the quartz ozone tube.

[0014] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects: 1. In this utility model, by arranging the negative ion generating unit and the ozone generating unit in the wind tunnel in a specific order of upstream negative ions and downstream ozone, a synergistic purification process of condensation and oxidation is formed, which significantly improves the removal efficiency of gaseous pollutants such as formaldehyde. 2. In this utility model, the negative ion output carbon brush is completely encapsulated in a closed casing, which fundamentally avoids the risk of users coming into contact with high-voltage components and meets the safety standards of home appliances. The negative ion carbon brush, which is fixed by a wire clamp, can be easily disassembled and installed without tools, which greatly facilitates the user's daily maintenance and component replacement.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Combination Figures 1 to 4 The ozone negative ion formaldehyde removal device shown includes an outer shell 1, a fan 2 and a dust cover 3 installed on the top of the outer shell 1, a horizontally penetrating wind tunnel 4 on the outer shell 1, an annular air outlet chamber 5 installed inside the wind tunnel 4, the annular air outlet chamber 5 being connected to the fan 2 via a flexible hose, rubber feet installed at the four corners of the bottom of the outer shell 1, a closed hood 6 installed at one end of the wind tunnel 4, a negative ion output carbon brush 7 rolled into a ring and tied tightly inside the closed hood 6, and a quartz ozone tube 8 installed inside the wind tunnel 4.

[0019] Among them, the closed cover 6 seals one end of the wind tunnel 4, so that when the annular air outlet cavity 5 emits air, it generates negative pressure to adsorb negative ions and output the negative ions generated by the carbon brush 7.

[0020] The quartz ozone tube 8 is located downstream of the air outlet of the annular air outlet cavity 5, and the negative ion output carbon brush 7 is located upstream of the annular air outlet cavity 5.

[0021] After the air forms a negative pressure, it first adsorbs negative ions, which then become charged and condense. The air then flows through the quartz ozone tube 8 and is deeply oxidized, avoiding mutual interference and forming a synergistic and orderly purification process.

[0022] The enclosed hood 6 is connected to the outer shell 1 and completely seals the port of the wind tunnel 4. Several wire clips 9 are fixed on the inner wall of the enclosed hood 6. The negative ion output carbon brush 7 is rolled into a ring and then inserted into several wire clips 9.

[0023] The high-voltage negative ion output carbon brush 7 is completely enclosed, effectively preventing the risk of electric shock to users. At the same time, it is fixed by the wire clip 9, making the installation and replacement of the negative ion output carbon brush 7 very simple.

[0024] The two sides of the quartz ozone tube 8 are connected to the inner wall of the wind tunnel 4 through the U-shaped bracket 10. The U-shaped bracket 10 is installed in the middle section of the wind tunnel 4, and the volume of the central hole inside the U-shaped bracket 10 is not less than 75% of the total volume of the bracket.

[0025] The highly transparent U-shaped bracket 10 ensures stable support for the quartz ozone tube 8 while greatly reducing airflow resistance, guaranteeing airflow and purification efficiency, and reducing equipment operating noise.

[0026] The edge of the open port at the other end of the wind tunnel 4 is designed with rounded corners. The main control module, power supply module and negative ion generator are also installed inside the outer shell 1. The output end of the power supply module is electrically connected to the main control module. The main control module is electrically connected to the discharge electrode of the negative ion generator and the quartz ozone tube 8 respectively.

[0027] Working Principle: When the device is powered on, the main control module starts the fan 2 and the negative ion generator. The fan 2 draws in indoor air, and the annular air outlet cavity 5 receives the air blown out by the fan 2 through the top hose and converts it into a uniform airflow around the inner wall of the wind tunnel 4. The negative ion generator generates high pressure and releases a high concentration of negative ions through the negative ion output carbon brush 7. The negative pressure causes the negative ions to move towards the annular air outlet cavity 5 and be carried by the airflow, giving the particles in the air a negative charge and initially activating some organic matter. The treated air continues to flow to the middle section of the wind tunnel and flows through the quartz ozone tube 8. Under the applied high pressure, the quartz ozone tube 8 ionizes the air to produce ozone, which reacts with the formaldehyde and other harmful gases that have been activated by negative ions, decomposing them into harmless substances such as carbon dioxide and water. Finally, the purified air is smoothly discharged from the other end of the wind tunnel 4 through the rounded corner port, completing the entire purification cycle.
