[0044] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0045] Please refer to Figures 1-6An air purifier includes an air outlet mechanism 1 and an air inlet mechanism 2 that are interconnected; a top air outlet 11 and a side air outlet 12 are respectively opened on the top and side wall of the air outlet mechanism 1; the air outlet mechanism 1 has an air guide assembly 13 and an air inlet 14 that is connected to the air inlet mechanism 2; the air guide assembly 13 is used to connect the air inlet 14 with the top air outlet 11 and / or the side air outlet 12.

[0046] It is understandable that by opening a top air outlet 11 and a side air outlet 12 on the top and side walls of the air outlet mechanism 1 respectively, air can be discharged in two directions, thereby allowing air to be directly delivered into the space where the user breathes, reducing the probability of clean air mixing with unpurified air.

[0047] In one embodiment, the air guiding assembly 13 includes a first air guiding member 131. When a first angle is formed between the air guiding surface of the first air guiding member 131 and the top of the air outlet mechanism 1, the air inlet 14 communicates only with the side air outlet 12. When a second angle is formed between the air guiding surface of the first air guiding member 131 and the top of the air outlet mechanism 1, the air inlet 14 communicates with both the top air outlet 11 and the side air outlet 12. When the air guiding surface of the first air guiding member 131 and the top of the air outlet mechanism 1 are perpendicular to each other, the air inlet 14 communicates only with the top air outlet 11. The angle of the first angle is smaller than the angle of the second angle. The first air guiding member 131 is configured to change the flow direction of the purified air, allowing the purified air to be discharged from either the side air outlet 12 or the top air outlet 11, or simultaneously from both the top air outlet 11 and the side air outlet 12, to meet different user needs. The first included angle is approximately 45°, and the second included angle is greater than 45° and less than 90°.

[0048] In another embodiment, the air guide assembly 13 includes a first air guide 131 and a second air guide 132. When the air guide surface of the first air guide 131 is flush with the air guide surface of the second air guide 132, the air inlet 14 is only connected to the side air outlet 12. When the air guide surface of the first air guide 131 and the air guide surface of the second air guide 132 are parallel to each other, the air inlet 14 is only connected to the top air outlet 11. When the air guide surface of the first air guide 131 and the air guide surface of the second air guide 132 form a third angle, the air inlet 14 is connected to both the top air outlet 11 and the side air outlet 12. By setting the first air guide 131 and the second air guide 132, the adjustment range of the air guide can be expanded, thereby allowing users to adjust the air volume and select the corresponding air outlet according to actual needs, making it more flexible. Specifically, when the air guide surface of the first air guide 131 is flush with the air guide surface of the second air guide 132, the included angle formed between the air guide surface of the first air guide 131 and the air guide surface of the second air guide 132 and the top of the air outlet mechanism 1 is approximately 45°.

The first guide member 131 and the second guide member 132 are respectively hinged to the side wall of the air outlet hood 15 through a rotating shaft to improve the stability of the first guide member 131 and the second guide member 132 when flipping. Specifically, the drive assembly includes two first drive motors, which are drivenly connected to the rotating shafts of the first guide member 131 and the second guide member 132, respectively.

[0050] In some embodiments, an auxiliary louver assembly 17 for controlling the opening and closing of the side air outlet 12 is provided inside the side air outlet 12. The auxiliary louver assembly 17 is mainly used to control the side air outlet 12 to close when the air inlet 14 is only connected to the top air outlet 11, and to open the side air outlet 12 when the air inlet 14 is connected to the side air outlet 12, so as to reduce the loss of air volume and ensure that the purified air is delivered in the designated direction.

[0051] In some embodiments, the auxiliary louver assembly 17 includes air guide louvers and a second drive motor; the second drive motor is drivenly connected to the input end of the air guide louvers so that the second drive motor controls the air guide louvers to rotate. By drivingly connecting the second drive motor to the air guide louvers, the angle of the air guide louvers can be changed, thereby changing the air outlet direction and the opening and closing state of the side air outlet 12, to meet different user needs.

In addition to adjusting the airflow direction by sensing the user's position through the sensor 18, the user can also manually adjust the airflow direction via the control panel 191.

[0054] In some embodiments, the air intake mechanism 2 includes an air intake assembly 21 and a filter assembly 22; the filter assembly 22 is disposed on the air intake side of the air intake assembly 21; the air outlet side of the air intake assembly 21 is connected to the air inlet 14 of the air outlet mechanism 1.

[0065] The air purifier in this invention has an automatic mode and a manual control mode, and the air outlet mechanism 1 has three air outlet modes regardless of whether it is in manual control mode or automatic mode.

[0066] Mode 1: The air guide surface of the first air guide 131 and the air guide surface of the second air guide 132 form a third angle, the angle of the third angle is greater than 0° and less than 45°. In this mode, the purified air will be divided into two parts.

[0069] The working principle of the automatic mode of the air purifier in this invention is as follows:

[0070] The air purifier can link its PM2.5 detection module with the air intake assembly 21 to control the operation and airflow of the air intake assembly 21.

[0071] S1: When the air purifier enters the automatic mode, adjust the air guide component 13 to mode one and keep it running in mode one for a first preset time a (5s < a < 20s). During the first preset time, the sensor 18 does not start.

[0072] S2: When the running time exceeds the first preset time, the sensor 18 is activated to detect whether there is anyone in front of the air purifier. The detection frequency is once per second, and it continues to detect for a second preset time b (5s < b < 10s). If the sensor 18 detects someone in front of the air purifier, it adjusts the air guide assembly 13 to enter mode two and maintains operation for a third preset time c (15s < c < 60s). During this period, the sensor 18 stops detecting.

[0073] S3: When the running time exceeds the third preset time, the sensor 18 is activated. If the sensor 18 detects that someone has appeared within the second preset time b, the detection time is increased to the third preset time c. If the sensor 18 detects that someone has left within the third preset time c, the air outlet mode of the air guide assembly 13 is adjusted to enter mode three, and mode three is maintained for a fourth preset time d (15s < d < 60s). When the running time exceeds the fourth preset time d, S2 is repeated.
