Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of air purification equipment technologies, and in particular, to an air purifier having one motor and two wind wheels.BACKGROUND

[0002] In existing technology, air purifiers are usually equipped with a motor and a wind wheel, that is, one motor drives one wind wheel to rotate. This technical solution has at least the following technical shortcomings: (1) due to one motor only driving one wind wheel to rotate, generated air volume is relatively small. If a larger air volume is wanted to obtain, it is needed to increase the motor power, increase the size of the wind wheel, and the overall size of the air purifier; (2) single trajectory of air intake and exhaust makes it difficult to effectively purify indoor air through the air purifiers. With rearing to the above technical issues, the present application provides a new technical solution that can increase the air volume of the air purifier and increase the trajectory of the inlet and outlet air.

[0003] It can be seen that the existing technology still needs improvement and enhancement.SUMMARY

[0004] In view of the shortcomings of the existing technology mentioned above, a purpose of the present disclosure is to provide an air purifier having one motor and two wind wheels, aiming to solve the technical problem of using a single motor and a single wind wheel in an air purifier in the existing technology.

[0005] In order to achieve the above objectives, the present disclosure adopts the following technical solutions.

[0006] An air purifier having one motor and two wind wheels, including a housing, where the housing is provided with a motor therein; one end of the motor is provided with a first wind wheel and the other end thereof is provided with a second wind wheel; one end of the housing is provided with a first air inlet, and the other end thereof is provided with a second air inlet; the housing is provided with a first air outlet at a position corresponding to the first wind wheel, and a second air outlet at a position corresponding to the second wind wheel.

[0007] Furthermore, the housing is provided with a first filter at a position corresponding to first air inlet and a second filter at a position corresponding to the second air inlet.

[0008] Furthermore, a main shaft of the motor is coaxially arranged with the housing.

[0009] Furthermore, the first wind wheel and the second wind wheel have a same specification and are symmetrically provided.

[0010] Furthermore, two first air outlets are provided on the housing, and two second air outlets are provided on the housing.

[0011] Beneficial effects: the present disclosure provides an air purifier having one motor and two wind wheels, which has at least the following technical advantages: compared to existing air purifiers with one motor and one wind wheel: (1) by driving two wind wheels simultaneously with one motor, the air volume and air purification efficiency of the air purifier are improved; (2) due to the presence of a first air inlet, a second air inlet, a first air outlet, and a second air outlet, the airflow trajectory becomes more complex, allowing indoor air to be purified more effectively.BRIEF DESCRIPTION OF DRAWINGS

[0012] FIG. 1 is a schematic structural diagram of an air purifier having one motor and two wind wheels provided by the present disclosure.DESCRIPTION OF EMBODIMENTS

[0013] The present disclosure provides an air purifier having one motor and two wind wheels. In order to render the purpose, technical solution, and effect of the present disclosure clearer and more specific, the following provides a further detailed explanation of the present disclosure. It should be understood that the specific embodiments described here are only used to explain the present disclosure and are not intended to limit the present disclosure.

[0014] Please refer to FIG. 1, the present disclosure provides an air purifier. The accompanying drawing is only used to explain the structural and is not drawn according to an actual proportional of an actual product. The drawing does not show all cross-sectional lines. The accompanying drawing only depicts the structures related to the present disclosure, and does not specifically depict some conventional structures. The arrows in the drawing represent a direction of airflow flow.

[0015] Terms "first", "second", etc. mentioned in this specification are only used to name similar structures for ease of explanation, and are not intended to limit the scope of the present application.

[0016] The air purifier having one motor and two wind wheels includes a housing 9, in which a motor 1 is provided therein. One end of the motor (shown as an upper end) is provided with a first rotor 21, and the other end thereof (shown as a lower end) is provided with a second rotor 22; one end of the housing (shown as the upper end) is provided with a first air inlet 911, and the other end thereof (shown as the lower end) is provided with a second air inlet 912; the housing is provided with a first air outlet 921 at a position corresponding to the first wind wheel, and a second air outlet 922 at a position corresponding to the second wind wheel.

[0017] As can be seen from the accompanying drawing, the housing is provided with a motor mounting bracket 19 therein, and the motor is mounted on the motor mounting bracket. A main shaft 11 of the motor extends from both ends of the motor, with one end connected to the first wind wheel and the other end connected to the second wind wheel.

[0018] Furthermore, the housing is provided with a first filter 31 at a position corresponding to the first air inlet and a second filter 32 at a position corresponding to the second air inlet. As shown in the accompanying drawing, the housing is provided with a first filter bracket 319 at a position corresponding to the first filter, and a second filter bracket 329 at a position corresponding to the second filter. The first filter is connected to the first filter bracket, and the second filter is connected to the second filter bracket.

[0019] Preferably, the main shaft of the motor is coaxially provided with the housing.

[0020] Preferably, the first wind wheel and the second wind wheel have a same specification and are symmetrically arranged. This setting is beneficial for ensuring dynamic balance during the rotation of the two wind wheels.

[0021] Preferably, there are two first air outlets 921 systematically provided on the housing. There are two second air outlets 922 systematically provided on the housing. This setting allows the purified air to be discharged from more air outlets, increasing the trajectory of air flow.

[0022] It can be understood that for those skilled in the art, equivalent substitutions or changes can be made based on the technical solution and concept of the present disclosure, and all these changes or substitutions should fall within the protection scope of the present disclosure.
