[0002] An air purifier is a device that filters particulate matter, harmful gases and other pollutants from indoor air, aiming to improve indoor air quality and provide users with a healthier breathing environment.

[0003] Traditional air purifiers are equipped with only one motor and one fan, resulting in limited purification area and efficiency. When a larger purification area is needed, it is usually achieved by increasing the motor speed. However, this method places high demands on motor performance, significantly increasing production costs. Furthermore, high speeds also generate considerable noise, negatively impacting the user experience.

[0004] Chinese patent CN222187263U discloses an air purifier with a multi-directional air duct structure. By setting two fans coaxially in the vertical direction, it can achieve air intake from the top and bottom and air exhaust from the middle, which can effectively increase the amount of air purified per unit time and improve the working efficiency of the air purifier.

[0005] The above-mentioned technical solution, which uses two fans coaxially arranged in the vertical direction to draw in air from the top and bottom and exhaust air from the middle, suffers from mutual interference between the airflow generated by the two fans, reducing the airflow efficiency. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a multi-fan air purifier. In this multi-fan air purifier, each fan has its own independent space, so they do not interfere with each other, thereby improving air output efficiency.

[0033] The following are specific embodiments of this utility model, in conjunction with the accompanying drawings. Figure 1-5 The technical solution of this utility model will be further described below, but this utility model is not limited to the following embodiments.

[0034] A multi-fan air purifier includes: a housing, a partition plate 200, a first fan 132, and a second fan 350. The partition plate 200 is disposed within the housing and divides the housing into an upper housing 100 and a lower housing 300. The upper housing 100 and the lower housing 300, together with the partition plate 200, form a first receiving cavity 131 and a second receiving cavity 322 that are not connected within the housing. It should be noted that the first receiving cavity 131 and the second receiving cavity 322 are not connected within the housing, meaning that gas in the first receiving cavity 131 cannot flow into the second receiving cavity 322 through the channels inside the housing, and vice versa. The first fan 132 is disposed in the first receiving cavity 131, and the second fan 350 is disposed in the second receiving cavity 322. The upper housing 100 is provided with a first air outlet 141, and the lower housing 300 is provided with a second air outlet 321. The air outlet direction of the first air outlet 141 is different from that of the second air outlet 321. By setting a partition plate 200 on the housing, the air purifier is divided into a first receiving cavity 131 and a second receiving cavity 322 that are not connected inside the housing, and two fans are respectively set in the two receiving cavities, so that the airflow generated by the two fans does not interfere with each other and improves the air outlet efficiency.

[0035] Specifically, the first fan 132 and the second fan 350 have different axial directions. In this embodiment, the axis of the first fan 132 is horizontal, and the axis of the second fan 350 is vertical. The first air outlet 141 is set on the top surface of the upper housing 100, and an air outlet grille 140 is provided on the first air outlet 141. The air outlet direction of the first air outlet 141 is vertical, and the air outlet direction of the second air outlet 321 is horizontal. By setting the first fan 132 and the second fan 350 with different axial directions, and setting the air outlet direction of the first air outlet 141 to be vertical and the air outlet direction of the second air outlet 321 to be horizontal, the air purifier can cover a wider area around the housing.

[0036] It should be noted that in this embodiment, the first fan 132 is a centrifugal fan. A centrifugal fan is a fluid machine that converts mechanical energy into gas pressure energy by generating centrifugal force through a high-speed rotating impeller. The centrifugal fan, through its streamlined impeller and diffuser optimized design, reduces airflow turbulence and energy loss, resulting in high operating efficiency. The second fan 350 is an axial flow fan. An axial flow fan is a fluid machine in which the gas flow direction is parallel to the fan impeller axis, resulting in even higher ventilation efficiency. In other embodiments, the first fan 132 and the second fan 350 may also use other fan types; this is not limited.

[0037] The multi-fan air purifier of the present invention further includes a first filter assembly 150 and a volute 130.

The filter screen 151 abuts against the first filter element 152, and the filter screen 151 is disposed outside the first filter element 152. The airflow entering from the first air inlet 111 is first coarsely filtered by the filter screen 151 and then finely filtered by the first filter element 152 before being discharged from the first air outlet 141. In this embodiment, the volute 130 includes a detachably connected first part 133 and a second part 134, which are connected to each other in a horizontal direction.

[0039] Preferably, the upper housing 100 includes a detachably connected front cover 110 and an inner housing 120. The filter screen 151 and the first filter element 152 are disposed in the inner housing 120, and the volute 130 is disposed on the inner housing 120. In this embodiment, the volute 130 and the inner housing 120 are integrally formed.
