Description

Technical Field

[0001] This utility model relates to the field of air supply filtration technology, specifically a high-efficiency air supply outlet sealed filtration mechanism. Background Technology

[0002] In modern air conditioning systems and air purification equipment, the filtration function of the air outlet is crucial. Its main role is to effectively clean pollutants from the air and provide a fresh and healthy air environment. However, existing filtration mechanisms have certain limitations in terms of sealing performance and filtration effectiveness, mainly in the following aspects:

[0003] Traditional filtration systems typically employ an open design, where gaps or incomplete seals may exist at the contact surface between the filter and the air outlet. This allows unfiltered pollutants in the air to enter the air outlet through these gaps, reducing air purification effectiveness. Furthermore, air leakage may occur at the edges of the filter, affecting the overall sealing and filtration performance of the device, resulting in incomplete pollution blocking.

[0004] Existing filtration systems are structurally complex, often requiring the disassembly of air outlets or other components to replace or clean the filters. This design not only increases the difficulty and cost of maintenance but may also affect the normal operating cycle of the equipment.

[0005] Traditional filtration systems typically increase airflow resistance, affecting the airflow rate at the air outlet. Especially with high-efficiency filtration, a significant pressure drop can occur as air passes through the filter, leading to reduced system energy efficiency.

[0006] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a high-efficiency air outlet sealed filter mechanism. Utility Model Content

[0007] The purpose of this invention is to provide a high-efficiency sealed air outlet filter mechanism to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A technical solution for a high-efficiency sealed air outlet filtration mechanism includes a filter box, a sealing ring, a primary filter, a secondary filter, a tertiary filter, and a flow guide frame.

[0010] The filter box has an air inlet at the air inlet end, its inner wall forms an L-shaped angle, and its side wall has an assembly hole.

[0011] The sealing ring is located at the edge of the air vent;

[0012] The primary, secondary, and tertiary filters are stacked sequentially inside the filter box, with the edge of the primary filter abutting against the sealing ring.

[0013] As a preferred technical solution, the airflow guide frame is provided in multiple sets, and the multiple sets of airflow guide frames are sequentially arranged on the adjacent sides of the primary filter, the secondary filter and the tertiary filter, and the inner wall is set with a slope, the slope being arranged along the air inlet direction.

[0014] As a preferred technical solution, the guide frame is provided with an inclined guide surface, the inclination direction of which forms an angle of 15°-30° with the airflow direction.

[0015] As a preferred technical solution, the primary filter is a coarse filter layer, the secondary filter is a HEPA high-efficiency filter layer, and the tertiary filter is an activated carbon composite filter layer.

[0016] As a preferred technical solution, the mounting hole is a threaded hole, and a bolt is used to pass through the mounting hole to achieve detachable fixation.

[0017] As a preferred technical solution, the L-shaped included angle extends continuously along the circumferential direction of the inner wall of the filter box to form a sealing groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention relates to a high-efficiency sealed air outlet filter mechanism. The sealing ring and the sealing groove structure formed by the L-shaped angle significantly improve the sealing performance between the air outlet and the filter screen, effectively preventing unfiltered air from entering the air outlet through gaps, thereby improving air purification efficiency. Simultaneously, the sequentially stacked primary, secondary, and tertiary filters achieve multi-stage filtration, further enhancing air cleanliness. Attached Figure Description

[0024] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution for a high-efficiency air outlet sealed filter mechanism, including a filter box 1, a sealing ring 2, a primary filter screen 3, a secondary filter screen 4, a tertiary filter screen 5, and a guide frame 6. The air inlet end of the filter box 1 is provided with an air outlet 13, the inner wall of which forms an L-shaped angle 11, and mounting holes 12 are opened on the side wall. The sealing ring 2 is located at the edge of the air outlet 13 to ensure a good sealing effect between the filter box 1 and the filter screen.

[0026] The primary filter 3, secondary filter 4, and tertiary filter 5 are stacked sequentially inside the filter box 1. The edge of the primary filter 3 abuts against the sealing ring 2 to prevent air from bypassing the filter and directly entering the air outlet. The primary filter 3 is a coarse filter layer used to remove larger particles from the air; the secondary filter 4 is a HEPA high-efficiency filter layer used to remove fine particles; and the tertiary filter 5 is an activated carbon composite filter layer used to adsorb harmful gases and odors from the air.

[0027] like Figure 3 As shown, multiple sets of airflow guide frames 6 are provided, and these multiple sets of airflow guide frames 6 are sequentially arranged on the adjacent sides of the primary filter 3, the secondary filter 4, and the tertiary filter 5. Their inner walls are sloped, with the slope facing the air inlet direction. The airflow guide frames 6 have inclined guide surfaces, with their inclination direction forming an angle of 15°-30° with the airflow direction, to guide the airflow smoothly through the filters, reduce airflow resistance, and improve filtration efficiency.

[0028] In this invention, the mounting hole 12 is a threaded hole, and a bolt is inserted through the mounting hole 12 to achieve detachable fixing, which facilitates the replacement and cleaning of the filter screen. The L-shaped included angle 11 extends continuously along the inner wall of the filter box 1 to form a sealing groove, further enhancing the sealing performance.

[0029] This utility model's high-efficiency air outlet sealed filter mechanism significantly improves the sealing performance between the air outlet and the filter screen by setting a sealing groove structure formed by a sealing ring 2 and an L-shaped included angle 11. This effectively prevents unfiltered air from entering the air outlet through gaps, thereby improving the air purification effect. At the same time, multi-stage filtration is achieved through the sequentially stacked primary filter screen 3, secondary filter screen 4, and tertiary filter screen 5, further enhancing the cleanliness of the air.
