Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to a dual-fan air purifier. Background Technology

[0002] With the increasing severity of air pollution, air purifiers are gradually entering homes and offices. Current air purifiers generally use a single fan and single filter structure, primarily achieving air purification through side or bottom air intake.

[0003] The existing technology has the following drawbacks:

[0004] The purification range is limited, making it difficult to simultaneously and efficiently treat near-ground pollutants (hair, debris) and suspended particles in the air.

[0005] Single-fan structures generate more noise and increase resistance at high air volumes, resulting in a poor user experience.

[0006] The airflow path is singular, the overall air exchange rate is low, and the purification efficiency is not ideal.

[0007] Therefore, there is an urgent need for an air purification device that can simultaneously purify air on the ground and in the air, improve air circulation efficiency, and reduce noise. Utility Model Content

[0014] The barrel-shaped filter element is arranged around the middle of the machine body and is used to filter the air entering from the air intake path around the machine body;

[0015] The top fan is arranged above the barrel-shaped filter element and is used to drive the air entering through the bottom air inlet path and the air inlet paths around the machine body to converge at the top of the machine body and be discharged from the top air outlet.

[0016] Furthermore, the bottom filter element is arranged on the base of the machine body.

[0017] Furthermore, the bottom fan and the top fan are composed of a motor and an air wheel and are used to drive the air to flow in the machine body.

[0018] Furthermore, the barrel-shaped filter element is a multi-layer composite filter element.

[0019] Furthermore, the barrel-shaped filter element includes a primary filter screen, a HEPA filter screen and an activated carbon layer and is used to filter suspended particles, bacteria, peculiar smells and gaseous pollutants.

[0020] Furthermore, the top air outlet is provided with air guiding blades for adjusting the air supply direction.

[0021] By means of the above solution, through the double-fan air purifier, adopting the air duct structure with independent air inlet at the bottom and around and unified air outlet at the top, by setting the bottom sheet-shaped filter element and the barrel-shaped filter element and respectively driving them by independent fans, double-path air purification is realized, and finally a unified air flow output is formed at the top, which can purify the ground air and the suspended air at the same time, is especially suitable for the environment with children or pets in the family, and improves the air purification speed and effect.

[0022] The above description is only an overview of the technical solution of the present invention. In order to be able to understand the technical means of the present invention more clearly and implement it according to the content of the description, the following takes the preferred embodiments of the present invention and combines them with the attached drawings to describe in detail as follows. Brief Description of the Drawings

[0023] Figure 1 is a schematic structural diagram of the double-fan air purifier of the present invention;

[0024] Figure 2 is a schematic diagram of the air inlet path and the air flow in the machine body of the double-fan air purifier of the present invention. Detailed Embodiments

[0025] The following combines the attached drawings and embodiments to further describe in detail the specific embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0026] Refer Figure 1 、 Figure 2As shown, this embodiment provides a dual-fan air purifier, including a body 1. Inside the body 1, from bottom to top, are a bottom purification module, a surrounding purification module, and a top exhaust module. The bottom purification module includes a sheet-like bottom filter element 2 and a bottom fan 3. The surrounding purification module includes a cylindrical filter element 4. The top exhaust module includes a top fan 5 and a top air outlet 6. The bottom filter element 2 is installed at the bottom of the body 1 and is used to filter the air entering through the bottom air intake path. Ground air is filtered by the bottom sheet-like filter element to remove large particles such as hair and dust. The bottom fan 3... Located above the bottom filter element 2, it drives the air to flow from bottom to top. After being pressurized by the bottom fan, the airflow enters the interior of the machine and is transported upwards. The barrel-shaped filter element 4 is arranged around the middle of the machine body and is used to filter the air entering from the air intake path around the machine body. The air enters the barrel-shaped filter element from the sides of the machine body and is filtered through multiple layers to remove pollutants such as PM2.5 and VOCs. The top fan 5 is located above the barrel-shaped filter element 4 and is used to drive the air entering from the bottom air intake path and the air intake path around the machine body to converge at the top of the machine body (and be transported to the top air outlet), and then discharged from the top air outlet 6.

[0027] In this embodiment, the bottom filter element 2 is located on the base of the machine body and is mainly used to filter pollutants such as large particles, hair, and dust.

[0028] In this embodiment, the bottom fan 3 and the top fan 5 are composed of a motor and a fan wheel, and are used to drive air to flow inside the body 1 (between the filter elements).

[0029] In this embodiment, the barrel-type filter element 4 is a multi-layer composite filter element.

[0030] In this embodiment, the barrel-type filter element 4 includes a pre-filter, a HEPA filter, and an activated carbon layer, used to filter suspended particles, bacteria, odors, and gaseous pollutants.

[0031] In this embodiment, the top air outlet 6 is equipped with air guide vanes to adjust the air delivery direction.

[0032] This utility model has the following technical effects:

[0033] 1) Wider purification range: Independent air intake at the bottom and around the sides achieves dual purification of air on the ground and in the space.

[0034] 2) High-efficiency dust and hair removal: The bottom filter element is close to the ground, which can quickly adsorb heavier pollutants such as hair and lint.

[0035] 3) Airflow optimization: Top air outlets enhance air circulation and improve indoor air exchange rate.

[0036] 4) Dual fan division of labor: Reduces the load on a single fan, improves purification efficiency, and reduces noise.

[0037] 5) Enhanced user experience: Fast purification speed and significant improvement in air quality, making it especially suitable for home and pet environments.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
