Description

Technical Field

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

[0002] Current air purifier designs typically use a circular impeller as the core component. While this design possesses certain hydrodynamic characteristics, it also has several shortcomings. First, the circular impeller structure results in an inoptimized airflow path and a lack of effective airflow guidance ducts. This directly leads to insufficient guidance and acceleration of the purified air, resulting in a smaller exhaust volume. Such a design not only reduces air purification efficiency but also negatively impacts the user experience, failing to meet the continuous air quality demands of modern homes and commercial environments.

[0003] Furthermore, due to the lack of a guiding structure, airflow is affected by irregular flow patterns as it passes through the impeller gaps, causing eddies and turbulent airflow. This undesirable airflow pattern increases airflow resistance, resulting in higher noise levels during equipment operation and failing to meet users' requirements for quiet operation. In many applications, such as offices, bedrooms, and hospitals, a quiet environment is particularly important; excessive noise not only interferes with users' lives and work but may also have negative health effects.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0028] like Figures 1 to 4As shown, this embodiment discloses an air purifier, including a body 1. The body 1 has an air mesh 2 inside, a purification system 3 below the air mesh 2, a fan wheel 4 above the air mesh 2, a first air guide component 5 outside the fan wheel 4, and a second air guide component 6 around the outer ring of the air mesh 2.

This utility model embodiment forms a curved air duct assembly 7 by setting a first air guide assembly 5 and a second air guide assembly 6, which can significantly improve airflow and reduce noise, including: (1) increasing air volume: the curved air duct design can optimize the airflow path and reduce the resistance during the airflow process.

The airflow flows from the second air duct 18 into the third air duct 21, and then flows out from the air outlets 8 above the third air duct 21, exiting to the outside of the air purifier, thus completing the air exhaust cycle.

[0034] like Figure 2As shown, in addition to the features mentioned above, this embodiment further specifies that: the partition 23 is connected to a first ring plate 24 at the end away from the top shell 22, and the distance between the first ring plate 24 and the top shell 22 is set to 14-20mm, that is, the width of the air outlet 8 is within the range of 14-20mm, preferably 17mm; the first ring plate 24 is in a vertical state, and an inclined plate 25 is integrally connected to the bottom of the first ring plate 24; a second ring plate 26 is integrally connected to the end of the inclined plate 25 away from the first ring plate 24, and the second ring plate 26 is in a vertical state.

The top of the filter 35 is fixedly connected to the third annular plate 32 for filtering and purifying air.

[0037] Working principle:

[0038] Under the vortex action of the impeller 4, external air is drawn in through the air inlet 34 and enters the body 1. It passes through the annular filter 35, which captures solid particles and other foreign objects in the air. The filtered and purified air enters the air chamber 36 inside the filter 35, and then passes through the air mesh 2 and enters the impeller 4. At the same time, under the rotation of the impeller 4 driven by the drive motor 14, the air flows out along the air duct assembly 7, that is, along the first air duct 16, the second air duct 18 and the third air duct 21, and finally exits from the air outlet 8 at the top of the third air duct 21. This optimizes the airflow path and provides a curved air duct for the airflow, thereby adjusting the air volume, which can not only increase the air volume but also reduce noise.

[0039] Tests have shown that the air purifier provided by this invention increases the airflow by at least 20m³ / h. 3 From the conventional 45m 3 / h increased to 68m 3 / h, while the noise level is reduced by 1-2dB, and the overall number of mounting screws is reduced from the conventional 48 to 9, which greatly improves production efficiency and product performance.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
