[0029] With people's pursuit of a comfortable life, there is a need for air purifiers that can purify room air and also function as fans. However, in existing air purifiers, the cord rotates with the airflow, posing a risk of cord breakage. To solve the above problem, this application provides an air purifier that resolves the issue of cord breakage risk in existing air purifiers when the cord rotates with the airflow.

[0030] In some embodiments, such as Figures 1-7 As shown, an air purifier is provided, including,

[0031] The base 1 is provided with an air inlet 121 and an air outlet 111, and a fan 2 is provided inside the base 1;

[0032] The rotating component 3 includes a fixed bracket 31, a drive motor 32, and a turntable 33. The fixed bracket 31 is connected to the base 1 and is located at the air outlet 111. The drive motor 32 is connected to the fixed bracket 31, and the turntable 33 is movably connected to the fixed bracket 31. The drive motor 32 can drive the turntable 33 to rotate.

[0033] Rotating head assembly 4, the turntable 33 is connected to the rotating head assembly 4, the rotating head assembly 4 is provided with an air outlet 43, the fan 2 can draw air in from the air inlet 121 and enter the air outlet 43 through the air outlet 111 to realize air outlet.

[0034] By connecting the fixed bracket 31 to the base 1, and fixing the drive motor 32 to the fixed bracket 31, the operation of the drive motor 32 causes the turntable 33 to rotate. The rotation of the turntable 33 drives the rotating head assembly 4 to rotate, thus achieving rotational air outlet. Since the drive motor 32 is fixedly set in the fixed bracket 31, the connecting wires on the stepper motor will not be twisted or deformed, thereby avoiding the connection wires from breaking. The structure is simple and ensures that the air purifier can rotate stably.

[0035] In some embodiments, such as Figures 3-5 As shown, the rotating assembly 3 also includes a drive gear 34, the output end of the drive motor 32 is connected to the drive gear 34, and the turntable 33 is provided with a gear ring, which meshes with the drive gear 34. The gear transmission design ensures smooth rotation.

[0036] In some embodiments, the drive motor 32 is a stepper motor, and the output end of the drive motor 32 is directly connected to the turntable 33 to drive the turntable 33 to rotate. As long as the turntable 33 can rotate, the connection method between the drive motor 32 and the turntable 33 is not limited.

[0037] In some embodiments, such as Figure 1 and Figure 7 As shown, the rotating head assembly 4 includes an air guide bracket 41 and an air outlet housing 42 connected to each other. The air outlet housing 42 is provided with the air outlet duct 43, and the air guide bracket 41 is connected to the turntable 33. The rotation of the turntable 33 drives the air guide bracket 41 to rotate, and the air guide bracket 41 in turn drives the air outlet housing 42 to rotate, thereby realizing the rotational air outlet.

[0038] In some embodiments, such as Figure 1 , Figure 6 and Figure 7 As shown, the air outlet end face of the base 1 near the air outlet 111 is inclined, the turntable 33 and the air guide bracket 41 are both parallel to the air outlet end face, and the end face of the air outlet housing 42 away from the air guide bracket 41 forms a first angle with the air guide bracket 41.

[0039] By tilting the air outlet end face and forming a first angle between the end face of the air outlet housing 42 away from the air guide bracket 41 and the air guide bracket 41, oblique air blowing is achieved. When the turntable 33 rotates, the orientation of the air outlet housing 42 will change with the rotation process, which can increase the air outlet range.

[0040] In some embodiments, such as Figure 1 and Figure 7 As shown, a second angle is formed between the air outlet end face and the horizontal plane, and the first angle and the second angle are equal. By making the first angle and the second angle equal, when the rotating head assembly 4 rotates to a certain angle, the end face of the air outlet housing 42 away from the air guide bracket 41 is parallel to the horizontal plane. At this time, the air outlet housing 42 emits air vertically, so that during the entire rotation of the air outlet housing 42, air can be emitted both at an angle and vertically, further increasing the air outlet range.

[0041] In some embodiments, the first included angle is 15°-60°. The size of the first included angle can be selected according to the air outlet range.

[0042] In some embodiments, such as 1 and Figure 7 As shown, the first included angle is 25° and the second included angle is 25°. By making the first included angle equal to the second included angle, when the rotating head assembly 4 rotates to a certain angle, the end face of the air outlet housing 42 away from the air guide bracket 41 is parallel to the horizontal plane. At this time, the air outlet housing 42 is upright and the air is discharged, so that during the entire rotation of the air outlet housing 42, the air can be discharged at an angle or upright, further increasing the air discharge range.

[0043] In some embodiments, the air outlet end face of the base 1 near the air outlet 111 is horizontally arranged, the turntable 33 and the air guide bracket 41 are both parallel to the air outlet end face, and the end face of the air outlet housing 42 away from the air guide bracket 41 forms a first angle with the air guide bracket 41. By forming the first angle between the end face of the air outlet housing 42 away from the air guide bracket 41 and the air guide bracket 41, that is, by tilting the end face of the air outlet housing 42 away from the air guide bracket 41, oblique air outlet can be achieved, and as the air outlet housing 42 rotates, the orientation of the air outlet housing 42 changes, increasing the air outlet range.

[0044] In some embodiments, such as Figure 1 As shown, the drive motor 32 is located on the central axis of the air outlet face. By positioning the drive motor 32 on the central axis of the air outlet face, the air purifier is subjected to uniform force, ensuring smooth rotation, reducing operating noise, and minimizing vibration.

[0045] In some embodiments, such as Figure 1As shown, the base 1 includes an upper housing 11 and a lower housing 12, which are detachably connected. The upper housing 11 has an air outlet 111, and the lower housing 12 has an air inlet 121. A filter element is installed inside the lower housing 12, and the fan 2 is located inside the upper housing 11. After a period of use, the filter element can be cleaned and replaced by disassembling the upper housing 11 and the lower housing 12.

[0046] In some embodiments, the air purifier further includes a circuit board connected to the mounting bracket 31, and the drive motor 32 electrically connected to the circuit board. The circuit board is fixed to the mounting bracket 31 and will not rotate with the rotating head assembly 4, thus preventing the connecting wires on the circuit board from being broken.
