Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, specifically to a vacuum cleaner airflow assembly. Background Technology

[0002] Vacuum cleaners are a common household cleaning tool with many uses. When using a vacuum cleaner, its internal airflow components work with filter cotton to filter the air.

[0003] Existing technology (Chinese patent publication number CN215305523U, published on December 28, 2021) discloses a dust extraction airflow assembly, a dust collection pile, and a cleaning system. The dust extraction airflow assembly includes a body, a filter element, and a baffle plate. The filter element is disposed within the body. The baffle plate includes a first surface and a second surface facing each other. The first surface is positioned opposite the air outlet surface of the filter element to form a baffle channel, and the second surface is positioned opposite the body to form an air outlet channel. The bottom end of the baffle channel is connected to the bottom end of the air outlet channel, allowing airflow discharged from the air outlet surface to enter the air outlet channel from the bottom end of the baffle channel. By placing the baffle plate between the body and the filter element, the airflow discharged from the filter element flows into the air outlet channel along the bottom end of the baffle plate under the action of the baffle plate, thereby lengthening the airflow path and reducing airflow noise.

[0004] Currently, when filtering airflow, a single filter structure is generally used, which has a poor filtration effect. Furthermore, when using a secondary filter structure, the two filter structures need to be installed on separate brackets, which requires more installation space inside the equipment, increases the overall space occupied by the equipment, and also increases costs. Utility Model Content

[0005] The purpose of this utility model is to provide a vacuum cleaner airflow assembly to solve the problems mentioned in the background art, which currently use a single filter structure for airflow filtration, resulting in poor filtration effect. Furthermore, when using a secondary filter structure, the two filter structures are installed on separate brackets, which requires a large installation space within the equipment and increases the overall space occupied by the equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a vacuum cleaner air duct assembly, including a body and an air intake mechanism inside it, wherein a mounting bracket is provided inside the body, a first filter assembly is installed below the mounting bracket, and a second filter assembly is provided above the mounting bracket, and the air intake mechanism is located outside the first filter assembly and the second filter assembly.

[0007] To further optimize this technical solution, the air intake mechanism includes an air inlet, a cyclone separation component, and a fan component. The air inlet is located at the bottom of the machine body, and the cyclone separation component is located above the air inlet. The fan component is located above the cyclone separation component.

[0008] To further optimize this technical solution, the first filter component is filter cotton, and the second filter component is HEPA paper.

[0009] To further optimize this technical solution, the first filter component has a bowl-shaped structure, and the lower part of the first filter component has a concave structure design, and an auxiliary support mechanism is provided on the upper part of the first filter component.

[0010] To further optimize this technical solution, the auxiliary support mechanism includes a central support component, a through groove, and a connector. The central support component has an arc-shaped structure design, and a through groove is provided inside the central support component. The upper part of the central support component is connected to the mounting bracket through the connector.

[0011] To further optimize this technical solution, an annular docking groove is provided above the mounting bracket, and the second filter assembly is connected to the mounting bracket through the docking groove.

[0012] To further optimize this technical solution, a first mounting groove is provided at the bottom of the mounting bracket to provide horizontal positioning for the mounting bracket when it is locked inside the machine body, and a second mounting groove is provided on the outside of the mounting bracket to provide vertical positioning for the mounting bracket when it is locked inside the machine body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The first filter component and the second filter component can be installed through a set of mounting brackets, which helps to save costs and installation space. The second filter component can perform secondary filtration, reducing the amount of dust discharged into the air and preventing dust from damaging the motor.

[0015] (2) By setting the first filter component in a bowl shape, the effective filtration area of ​​the filter cotton can be increased, and the filtration effect can be improved. At the same time, the bottom is recessed, which can also increase the distance between it and the channel below, and prevent airflow blockage.

[0016] (3) The middle support can provide stable support for the middle part of the first filter assembly, so that it can maintain its own stability, maintain the bowl structure, prevent the first filter assembly from deforming, and ensure its filtration effect. Attached Figure Description

A second mounting groove 13 is provided outside the mounting bracket 6 to provide vertical positioning for the mounting bracket 6 inside the body 1.

[0025] The mounting bracket 6 provides mounting support for the first filter assembly 5 and the second filter assembly 7, reducing the number of brackets required. At the same time, the mounting bracket 6 can be installed in the body 1 by being snapped into the first mounting groove 12 and the second mounting groove 13, thus maintaining good stability of the mounting bracket 6.

[0029] The first filter component 5 with its bowl-shaped structure can increase its filtration area and improve the filtration effect. At the same time, it can also increase the distance between the first filter component 5 and the lower airflow channel to prevent airflow blockage. An adhesive layer can also be provided on the surface of the middle support 8 to improve the connection stability between the middle support 8 and the first filter component 5. A corresponding adhesive layer can also be provided in the docking groove 11 to bond the second filter component 7 and prevent it from moving.
