Description

Technical Field

[0001] This utility model relates to the field of air sterilizer technology, and more specifically, to an air duct structure for an air sterilizer. Background Technology

[0002] Air purifiers filter air through internal filter components. Current technology typically uses a multi-layered filter structure with the filter screen perpendicular to the airflow direction, achieving good filtration results. However, this results in significant airflow resistance, affecting the purified airflow. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a low-resistance air duct structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an air duct structure for an air sterilizer, comprising an air inlet section, a filter section, and an air outlet section arranged sequentially from bottom to top. The air inlet section is provided with an air inlet, the air outlet section is provided with an air outlet, and the filter section is provided with multiple filter components. The multiple filter components are arranged equidistantly in the horizontal direction. The multiple filter components include a first filter component near the air inlet section and a second filter component near the air outlet section. The first filter component and the second filter component are spaced apart so that the first filter component and the second filter component are staggered in the vertical direction.

[0005] Furthermore, a bracket extending from one end toward the air outlet section to the other end toward the air inlet section is provided within the filter section, and the filter assembly is embedded within the bracket.

[0006] Furthermore, the bracket includes two limiting plates, each of which is provided with a support plate extending toward the other, and the filter assembly is placed on the support plate.

[0007] Furthermore, the filter assembly includes a support frame, and a baffle is provided on the top surface of the support frame. When the filter assembly is placed on the support plate, the baffle abuts against the support plate.

[0008] Furthermore, the top of the support frame is provided with an outwardly inclined elastic sheet, which abuts against the limiting plate when the filter assembly is placed on the support plate.

[0009] Furthermore, a flow guide is provided at the bottom of the support frame. The flow guide includes a first flow guide plate and a second flow guide plate. The ends of the first flow guide plate and the second flow guide plate facing the air inlet are connected to each other so that the first flow guide plate and the second flow guide plate are both inclined.

[0010] In summary, this utility model has the following beneficial effects:

[0011] Two adjacent first filter components form an air inlet channel at the end near the air inlet section. The second filter component is located inside the air inlet channel. The airflow entering the air inlet channel is diverted by the second filter component, impacting the first filter components on both sides and flowing into the corresponding filter channels, ensuring filtration efficiency. Simultaneously, at the end facing the air outlet section, two adjacent second filter components form an air outlet channel. Without the obstruction of the first filter components, the corresponding two filter channels can converge in the air outlet channel, reducing airflow resistance and ensuring sufficient airflow.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] See Figures 1 to 3 This embodiment discloses an air duct structure for an air sterilizer, including an air inlet section 100, a filter section 200, and an air outlet section 500 arranged sequentially from bottom to top. The air inlet section 100 is provided with an air inlet 110, and a fan 120 is installed in the air inlet section 100 at a position corresponding to the air inlet 110. The air inlet section 100 is located at the bottom, and the air outlet section 500 is located at the top. Driven by the fan 120, air enters the filter section 200 from the air inlet 110 at the bottom for filtration and is then blown out from the air outlet 510 at the top.

[0018] Multiple filter components for filtering impurities in the air are provided within the filter section 200. These filter components are arranged equidistantly in the horizontal direction, including a first filter component 300 near the air inlet section 100 and a second filter component 400 near the air outlet section 500. The first filter component 300 and the second filter component 400 are spaced apart so that they are staggered in the vertical direction. Multiple filter channels 230 are formed between adjacent first filter components 300 and second filter components 400. Due to the staggered arrangement of the first filter components 300 and second filter components 400 in the vertical direction, adjacent first filter components 300 form an air inlet channel 210 at the end near the air inlet section 100. The second filter component 400 is located within the air inlet channel 210. The airflow entering the air inlet channel 210 is diverted by the second filter component 400, impacting the first filter components 300 on both sides and flowing into the corresponding filter channels 230, thus ensuring filtration efficiency. Meanwhile, at one end facing the air outlet section 500, the two adjacent second filter components 400 form an air outlet channel 220. Since there is no obstruction from the first filter component 300, the two corresponding filter channels 230 can converge in the air outlet channel 220, which can reduce the air outlet resistance and thus ensure the air outlet volume.

[0019] The filter assembly includes a rectangular support frame 310, within which a filter screen 320 is disposed. A bracket 240 extending from one end toward the air outlet section 500 to the end toward the air inlet section 100 is disposed within the filter section 200. The bracket 240 includes two limiting plates 241, which form a mounting groove 242. Each limiting plate is also provided with a support plate 243 extending toward the other, forming an L-shaped structure with the limiting plates 241. A baffle 311 extending horizontally is disposed on the top surface of the support frame 310. During filter assembly installation, the support frame 310 is inserted into the mounting groove 242 until the baffle 311 abuts against the support plate 243, thereby fixing the filter assembly.

[0020] To ensure stability during filter assembly installation, an outwardly inclined elastic sheet 312 is installed on the top surface of the support frame 310. When the filter assembly is placed on the support plate 243, the elastic sheet 312 abuts against the limiting plate 241. The elastic sheet 312 is made of iron. When the elastic sheet 312 contacts the limiting plate 241, it is subjected to pressure and deforms. The elastic sheet 312 increases the friction between itself and the limiting plate 241 through its own elasticity, thereby enhancing the stability of the filter assembly during installation.

[0021] The bottom of the support frame 310 is provided with a flow guide, which includes a first flow guide plate 313 and a second flow guide plate 314. The ends of the first flow guide plate 313 and the second flow guide plate 314 facing the air inlet 110 are connected to each other so that the first flow guide plate 313 and the second flow guide plate 314 are both inclined and form a triangular structure. The flow guide can divert the airflow to enter each filter channel 230, thereby enhancing the filtration efficiency.

[0022] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
