Description

Technical Field

[0001] This application relates to the field of air purification technology, specifically to an air purification device. Background Technology

[0002] Currently, the main pollutants in indoor air are formaldehyde, odors, and dust. Therefore, air purification devices are generally equipped with filters, negative ion generators, and ozone generators. Dust is removed through the filters; negative ions combine with air pollutants such as dust, bacteria, and viruses, causing them to clump together and settle, thus purifying the air; ozone has very strong oxidizing properties, capable of oxidizing and decomposing harmful substances in the air, such as formaldehyde and benzene, converting them into harmless substances such as water and carbon dioxide. Ozone can also destroy the cell walls and cell membranes of bacteria and viruses, rendering them inactive, thus achieving sterilization and disinfection. Both ozone and negative ions can decompose odor molecules in the air, such as cigarette smoke and pet odors, making the air fresher.

[0003] To purify the air, the filter, negative ion generator, and ozone generator need to be in direct contact with the air duct of the purification device. Since the air duct is generally located inside the purification device, only a simple installation structure suitable for lightweight installation tools is suitable for installing the filter, negative ion generator, and ozone generator. To avoid disrupting the air duct's flow, the filter, negative ion generator, and ozone generator are installed separately within the air duct. However, this dispersed installation method lacks the stability of a simple installation structure, easily leading to positioning errors during installation. Inaccurate installation of the filter, negative ion generator, and ozone generator within the air duct directly affects the purification effect of each component, reducing the purification efficiency of the air purifier.

[0033] An air purification device, as shown in the attached Figure 1-4 As shown, it includes:

[0034] The housing 1 has an air inlet 11 and an air outlet 12 at both ends for air circulation;

[0035] The frame 2 is disposed inside the housing 1. The frame 2 includes a fan assembly 21, a filter assembly 22, a negative ion assembly 23 and an ozone assembly 24. The frame 2 has a through chamber. The chamber is connected to the air inlet 11 and the air outlet 12 of the housing 1. The chamber sequentially includes a first chamber 25 and a second chamber 26 along the air flow direction 20.

[0036] The first chamber 26 is provided with a first mounting structure for installing the fan assembly 21 and a second mounting structure for installing the filter assembly 22. The second chamber 26 is provided with a third mounting structure for installing the ozone assembly 24 and a fourth mounting structure for installing the negative ion assembly 23.

[0037] Compared with the prior art, this application has the following advantages: On the integrated frame, installation structures adapted to the fan assembly, filter assembly, negative ion assembly and ozone assembly are set respectively, which can achieve stable and accurate installation of each component while simplifying the installation, ensuring the purification effect of each component and improving the purification efficiency of the air purification device.

[0038] Specifically, a limiting step 251 is provided on the inner side wall of the first chamber 25. The limiting step 251 includes a first step surface 252 and a second step surface 253 that are connected to each other. The first step surface 252 is closer to the second chamber 26 than the second step surface 253. The first mounting structure includes the first step surface 252. The fan assembly 21 is installed in the first chamber 25 corresponding to the first step surface 252.

[0039] In addition, a guide strip 254 is provided on the first step surface 252. When the fan assembly 21 is installed on the first mounting structure, the outer side of the fan assembly 21 is attached to the surface of the guide strip 254.

[0040] Specifically, the second mounting structure includes a second stepped surface 253. The filter assembly 22 is installed in the first chamber 25 between the second stepped surface 253 and the opening of the first chamber 25. When the filter assembly 22 is installed in the second mounting structure, the inner end face of the filter assembly 22 abuts against the second stepped surface 253, the outer side face of the filter assembly 22 is in contact with the inner wall of the first chamber 25, and the outer end face of the filter assembly 22 is flush with the opening of the first chamber 25.

[0041] Within the first chamber 25, the fan assembly 21 is located near the second chamber 26, while the filter assembly 22 is located near the opening of the first chamber 25. Driven by the fan assembly 21, the airflow direction 20 within the chamber is from the first chamber 25 to the second chamber 26. Therefore, the first chamber 25 is under negative pressure, while the second chamber 26 is under positive pressure. Outside air is drawn into the first chamber 25 through its opening. Since the filter assembly 22 is located near the opening of the first chamber 25, the air entering the first chamber 25 first passes through the filter assembly 22 to remove dust. The fan assembly 21 continuously operates in the clean air after dust filtration, reducing dust adsorption caused by long-term operation, improving the cleanliness within the chamber, and avoiding secondary pollution during the purification process.

[0042] It should be noted that the greater the negative pressure suction capacity of the first chamber 25, the greater the resistance that air can overcome as it passes through the filter element assembly 22. This allows for the use of filter elements with smaller gaps to improve the filtration capacity for smaller dust particles, or for filter elements to maintain good filtration capacity even when nearing saturation, thereby improving the filtration capacity of the filter assembly 22. Therefore, the cross-sectional area of ​​the second chamber 26 perpendicular to the flow direction 20 is smaller than that of the first chamber 25 perpendicular to the flow direction 20. This causes the air entering the second chamber 26 from the first chamber 25 to be compressed and its flow velocity to increase, promoting the rapid flow of air from the first chamber 25 into the second chamber 26 and facilitating negative pressure suction within the first chamber 25.

[0043] With the combined action of the first step surface 252 of the second chamber 26 and the guide bar 254 of the first chamber 25, the fan assembly 21 is accurately and stably installed in the first chamber 25 on the side close to the second chamber 26, that is, installed at the junction of the first chamber 25 and the second chamber 26, thus ensuring the operating effect of the fan assembly 21.

[0044] With the combined action of the second step surface 253 of the first chamber 25 and the inner wall of the first chamber 25, the filter assembly 22 is accurately and stably installed at the opening of the first chamber 25, so that the outside air can enter the first chamber 25 only after the dust is completely filtered out by the filter assembly 22, thus ensuring the filtration and purification effect of the filter assembly 22.

[0045] In another exemplary embodiment, the third mounting structure includes a groove 261 provided on the inner wall of the second chamber 26. The grooves 261 are arranged in pairs facing each other, and the extension direction of the grooves 261 is along the air flow direction 20. When the ozone component 24 is installed to the third mounting structure, both ends of the ozone component 24 are inserted into the grooves 261.

[0046] Specifically, the ozone component 24 is an ozone ceramic sheet. When the ozone ceramic sheet is installed in the third mounting structure, both ends of the ozone ceramic sheet are inserted into the sliding groove 261, and the surface of the ozone ceramic sheet is parallel to the air flow direction 20. Since the ozone generated by the ozone ceramic sheet is generated from its surface, it achieves maximum contact area with the air in the second chamber 26, thus realizing the ozone purification effect on the air.

[0047] It should be noted that the surface of the ozone ceramic sheet is parallel to the airflow direction 20, which reduces the obstruction of airflow by the ozone ceramic sheet and ensures the efficiency of airflow. The ozone generated by the ozone ceramic sheet is carried away after reacting with the passing air, reducing the amount of ozone remaining in the second chamber 26 and preventing ozone from corroding the internal components of the air purification device.

[0048] Specifically, the fourth mounting structure includes a first through hole 262, which is located on the inner wall of the second chamber 26 between the slide grooves 261. When the negative ion component 23 is installed in the fourth mounting structure, it passes through the first through hole 262. The negative ion component 23 is a negative ion generator. When the negative ion generator is installed in the fourth mounting structure, its main body can be fixed to the outer wall of the frame 2. The emission needle 231 of the negative ion generator is inserted into the first through hole 262 and extends into the second chamber 26, thereby generating negative ions that purify the air within the second chamber 26.

[0049] It should be noted that the slide 261 and the first through hole 262 are positioned and installed by inserting the ozone component 24 and the negative ion component 23 respectively. The installation process is simple, the positioning is accurate, and the installation is stable and reliable, ensuring the purification effect of the ozone component 24 and the negative ion component 23.

[0050] In another exemplary embodiment, the air inlet 11 of the housing 1 is provided with an air inlet hood 13 and an adapter plate 14. One side of the adapter plate 14 is connected to the frame 2, and the other side of the adapter plate 14 is connected to the air inlet hood 13. A second through hole 141 corresponding to the filter assembly 22 is opened in the middle of the adapter plate 14. A bracket 131 protrudes from the middle of the air inlet hood 13 toward the adapter plate 14. When the air inlet hood 13 is connected to the adapter plate 14, the bracket 131 abuts against the outer end face of the filter assembly 22, further restricting the filter assembly 22 and preventing the filter assembly 22 from sliding out of the opening of the first chamber 25 due to the loss of the suction force of the fan assembly 21 when the air purification device is not running.

[0051] For details, see attached. Figure 4-5As shown, the outer edge of the adapter plate 14 is provided with a protruding ring 142 extending towards the air inlet shroud 13. The inner wall of the protruding ring 142 is provided with a slot 143. The outer edge of the air inlet shroud 13 is provided with a locking block 132 that cooperates with the slot 143. The connection between the air inlet shroud 13 and the adapter plate 14 can be achieved by aligning the locking block 132 with the slot 143 and locking it in.

[0052] In another exemplary embodiment, an air outlet hood 15 is provided at the air outlet 12 of the housing 1, and the air outlet hood 15 faces the second chamber 26. The purified air in the second chamber 26 is discharged through the air outlet hood.

[0053] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
