[0050] The present invention will be described in further detail below through the accompanying drawings and examples, through which the features and advantages of the present invention will become more clearly understood.

[0051] The word "exemplary" is used exclusively herein to mean "serving as an example, example, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0052] According to the utility model, an air purifier with a dual-motor and dual-wind wheel top air outlet structure is provided. Figure 1-2 As shown, an air outlet 2 is provided at the upper end of the purifier body 1, a first fan 3 is provided below the air outlet 2, and a first filter 4 is provided below the first fan 3;

[0053] A second fan 5 is provided below the first filter 4, and a second filter 6 is provided between the second fan 5 and the first filter 4;

[0054] A first air inlet 71 is provided on the circumference of the first filter 4 , and a second air inlet 72 is provided on the bottom of the second fan 5 ;

[0055] The wind force generated by the first fan 3 and the second fan 5 is directed vertically upward.

[0056] Traditional air purifiers typically use a single fan. When purification efficiency needs to be improved, this is often achieved by increasing the fan speed. Increasing fan speed increases motor quality control requirements and noise. In this utility model, the efficiency of the air purifier is improved by increasing the number of fans.

[0057] Furthermore, when implementing the present invention, it was found that when dual motors or multiple fans are combined in parallel, which is easier to imagine, there will be interference between the multiple fans, that is, the wind force generated by the multiple fans will be disturbed, resulting in reduced efficiency of the purifier.

[0058] In the present invention, by arranging the first fan and the second fan vertically, the problem of mutual interference between the multiple fans is solved, so that the purification efficiency can be superimposed to the greatest extent.

[0059] Specifically, if Figure 1 As shown, an air outlet 2 is provided at the upper end of the purifier body 1, a first fan 3 is provided below the air outlet 2, a first air inlet 71 is circumferentially provided below the first fan 3, a second fan 5 is provided below the first air inlet 71, and a second air inlet 72 is provided at the bottom of the second fan 5; the wind force generated by the first fan 3 and the second fan 5 is directed vertically upward.

[0060] Furthermore, a first filter 4 is provided at the first air inlet, and a second filter 6 is provided between the first filter 4 and the second fan 5 .

[0061] Specifically, if Figure 2 As shown, when the purifier is working, the second fan works to discharge the air at the second air inlet upward, so that the air passes through the second filter and enters the first filter and is discharged from the air outlet; further, when the first fan works, it accelerates the upward discharge of the air inside the first filter, so that the inside of the first filter is under negative pressure, and the air around the first filter is affected by the negative pressure and enters the first filter through the first filter, thereby purifying the air, and the purified air is discharged from the air outlet.

[0062] In a preferred embodiment, the axes of the first fan 3, the first filter 4, the second fan 5, and the second filter 6 are collinear.

[0063] In a preferred embodiment, Figure 1 As shown, the first filter 4 is trumpet-shaped, with openings at both ends, and the upper opening is larger than the lower opening. This trumpet-shaped design not only increases the area of ​​the first filter, improving the air purification capacity, but also reduces the collision between the airflow filtered by the first filter and the airflow discharged upward by the second fan, reducing disturbances between the two airflows.

[0064] Specifically, if Figure 2 As shown, the air flowing in from the second air inlet 72 flows out through the second fan 5, the second filter 6, the lower opening of the first filter 4, the upper opening of the first filter 4, the first fan 3 and the air outlet 2 in sequence;

[0065] The air flowing in from the first air inlet 71 flows out through the first filter 4 , the upper opening of the first filter 4 , the first fan 3 and the air outlet 2 in sequence.

[0066] In a preferred embodiment, Figure 3 、 4 As shown, the first fan 3 and the second fan 5 each include an upper shell 31, a motor 32, a motor fixing frame 33, a wind wheel 34 and a lower shell 35.

[0067] The upper shell 31 and the lower shell 35 can be buckled together to form a fan housing, and an air duct running through the fan housing is provided.

[0068] The motor fixing frame 33 is disposed in the air duct, the motor 32 is fixed on the motor fixing frame 33 , and the wind wheel 34 is mounted on the rotating shaft of the motor 32 .

[0069] It should be noted that the sizes and shapes of the specific components of the first fan 3 and the second fan 5 can be the same or different, and are not limited in the present invention.

[0070] Further preferably, a shock-absorbing rubber pad 36 is provided at the contact position between the motor fixing bracket 33 and the motor 32 .

[0071] In a preferred embodiment, Figure 1 As shown, in the first fan 3, the lower shell 35 is trumpet-shaped, so that the lower part of the lower shell 35 can be sleeved together with the upper part of the first filter 4, thereby enhancing the airtightness of the connection between the two.

[0072] In a preferred embodiment, the diameter of the lower opening of the first filter screen 4 is larger than the diameter of the air duct of the second fan 5 .

[0073] In the present invention, there is no limitation on the specific materials of the first filter 4 and the second filter 6. Those skilled in the art can select the filter materials commonly used in the field according to actual needs. Furthermore, the first filter 4 and the second filter 6 can adopt a single filtering structure or a combination of multiple filtering results.
