Description

Technical Field

[0001] The utility model relates to an air purifier with a dual-mode air outlet, belonging to the field of air purification. Background Art

[0002] In the modern field of air purification, the diversity and efficiency of the air outlet mode have always been important directions for research and development. Traditional air purification equipment often only has a single air outlet mode and is difficult to meet the increasingly complex and diverse usage requirements.

[0003] With the continuous progress of technology and the improvement of people's living standards, the requirements for air circulation and environmental comfort are also getting higher and higher. In many scenarios, such as large industrial workshops, commercial places, office areas, and home environments, etc., it is required that air purification equipment can flexibly adjust the air outlet mode according to different situations.

[0004] In commercial and office places, people have relatively high requirements for air comfort and uniformity. The traditional single air outlet mode may cause excessive or insufficient local airflows, affecting the body feeling comfort of indoor personnel, and even may cause the flying of dust or the accumulation of peculiar smells.

[0005] In the home environment, the ventilation requirements of different rooms and activity areas are also different. For example, the kitchen needs a strong exhaust air volume to remove cooking fumes during cooking, while the bedroom requires a softer and more uniform air current to ensure the sleep quality.

[0006] In the existing air purification technologies, although some equipment can achieve the adjustment of air volume, they often cannot take into account the advantages of both the large air volume mode and the jet air outlet mode at the same time. The large air volume mode can quickly achieve the air exchange of the overall space, but it is inadequate when precise air supply is required, avoiding air flow disturbance, or improving the local air purification effect. The jet air outlet mode can concentrate the air current to a specific area, but its coverage range is relatively narrow and cannot meet the requirements of large-area ventilation.

[0007] In summary, the existing air purification equipment has limitations in the air outlet mode and cannot meet the complex requirements for air circulation in various scenarios. Therefore, developing an air purification and ventilation technology with both large air volume and jet air outlet dual modes has become an urgent problem to be solved in the current air purification field, with important practical significance and broad application prospects.

[0031] (3) The air outlet component 4 has a central circular air duct and a circumferential annular air duct, which can simultaneously form an upward air flow and an air flow in the circumferential direction. This design can provide more diverse air flow patterns to adapt to different use environments and requirements.

[0032] (4) The jet air duct assembly 5 can be rotatably installed on the air outlet assembly 4, which means that the user can adjust the direction of the jet air duct as needed to optimize air flow and purification effect.

[0053] The jet air duct assembly 5 can be rotatably installed, providing the ability to flexibly adjust the airflow direction to adapt to different usage environments.

[0054] Through the jet action of the jet air outlet, the circulation of indoor air can be strengthened, improving the overall purification efficiency of the air purifier.

[0055] The working principle of the present utility model is:

[0056] (1) Air filtration: Air is first filtered through the filter element assembly 1. The filter element assembly is located at the lower end of the volute assembly 2 and is hermetically connected to the volute assembly to ensure that the air is effectively filtered before entering the fan assembly.

[0057] (2) Air delivery: The filtered air is delivered to the fan assembly 3. The fan assembly is installed on the upper part of the volute assembly and is responsible for further diverting the air.

[0058] (3) Air distribution: The fan assembly 3 diverts the air to the upper air outlet assembly 4. The air outlet assembly 4 has a central circular air duct and a circumferential annular air duct, which are respectively used to form an upward airflow and a circumferential airflow. The upward airflow not only blows directly to the outside, but can also enter the jet air duct assembly at the same time.

[0059] (4) Damper control: The damper 8 is installed between the upper air outlet plate 6 and the lower air outlet plate 6, and the opening and closing of the damper are controlled by a damper drive assembly (including a damper synchronous motor 10 and a damper gear 9), thereby realizing the switching between the circumferential air flow and the upward air flow.

[0060] (5) Dual-mode air outlet: According to the position of the damper, air can enter the air outlet assembly through the air inlet holes of the upper air outlet plate 7 and the lower air outlet plate 6, forming an upward or circumferential air flow. The opening and closing of the damper allow switching or combination between the two air outlet modes.

[0061] (5) Jet air duct adjustment: The jet air duct assembly 5 is rotatably installed on the air outlet assembly 4, and the direction of the jet air duct is controlled by a transmission assembly (including a rotary bearing 11, a bearing gear ring 12, a rotating head gear 13 and a rotating head synchronous motor 14).

[0062] (6) Jet formation: The air flow passes through the air inlet of the jet air duct frame 15, is guided and accelerated by the arc-shaped guide plate 17, and then forms a jet through the jet air outlet of the support frame 16, and finally jets to the outside through the external communication hole on the jet air duct housing 18.

[0063] Through the above structure, the air purifier realizes the effective circulation and purification of indoor air. The central circular air duct and the circumferential annular air duct provide diversified air flow patterns, and the rotatable installation of the jet air duct assembly 5 realizes the adjustment of the air flow direction according to needs, optimizing the air flow and purification effect.
