Abstract

An air purification device includes a movement portion configured to move the air purification device to a target region; and a purification portion configured to purify air in the target region to improve air quality of the target region.

First claim

The invention claimed is:

1. An air purification device, comprising:
a movement portion configured to move the air purification device to a target region; and
a purification portion configured to purify air in the target region to improve air quality of the target region;
a heating portion configured to increase environmental temperature around the air purification device to accelerate release of harmful substances from the environment.

2. The air purification device according to claim 1 , further comprising:
a monitoring portion configured to monitor the air quality to determine the target region, wherein the target region is determined as having an air quality lower than a predetermined standard air quality.

3. The air purification device according to claim 2 , wherein the monitoring portion comprises an infrared sensor configured to measure the air quality.

4. The air purification device according to claim 1 , further comprising:
a control portion configured to acquire a movement path for the target region to enable the movement portion to drive the air purification device to move according to the movement path.

5. The air purification device according to claim 4 , wherein the control portion is further configured to receive the movement path sent by an electronic device coupled with the control portion.

6. The air purification device according to claim 4 , wherein the control portion is configured to automatically generate the movement path.

7. The air purification device according to claim 1 , wherein the purification portion comprises:
a recovery portion configured to cause inflow of air;
a filter portion configured to filter out pollutants from the air; and
a delivery portion configured to deliver filtered air.

8. The air purification device according to claim 7 , wherein the recovery portion comprises a fan.

9. An air purification system, comprising a charging station, and an air purification device that includes:
a movement portion configured to move the air purification device to a target region;
a purification portion configured to purify air in the target region to improve air quality of the target region; and
a built-in battery configured to power to the air purification device when the air purification device is separated from the charging station, and to couple with the charging station for charging,
wherein the air purification device is integrated with a heater configured to heat up an environment to facilitate accelerated release pollutants from the environment for the purification portion to absorb.

10. The air purification system according to claim 9 , wherein the air purification device further comprises:
a power level detection portion configured to detect remaining power level of the built-in battery, wherein when the remaining power level of the built-in battery is lower than a predetermined value, the power level detection portion sends an alarm message indicating lower power state of the movement portion, such that the movement portion drives the air purification device to return to the charging station for charging the built-in battery.

11. The air purification system according to claim 9 , wherein:
the charging station comprises a wireless charging transmitter;
the air purification device comprises a wireless charging receiver; and
the wireless charging transmitter is configured to couple with the wireless charging receiver wirelessly to supply power to the air purification device.

12. The air purification system according to claim 9 , wherein:
the charging station comprises a power output interface;
the air purification device comprises a power input interface; and
the power output interface is configured to couple with the power input interface to supply power to the air purification device.

13. The air purification system according to claim 9 , further comprising:
a monitoring portion configured to monitor air quality to determine the target region, wherein the air quality of the target region is lower than a predetermined standard air quality.

14. The air purification system according to claim 9 , further comprising:
a control portion configured to acquire a movement path for the target region to enable the movement portion to drive the air purification device to move according to the movement path.

15. The air purification system according to claim 14 , wherein the control portion is configured to receive the movement path sent by an electronic device coupled with the control portion.

16. The air purification system according to claim 14 , wherein the control portion is configured to automatically generate the movement path.

17. The air purification system according to claim 16 , further comprising a plurality of air purification devices configured to function collectively to purify air in a space optimally.

18. The air purification system according to claim 17 , wherein the plurality of air purification devices include at least one of a humidifier, a vacuum machine, or a wet-cleaning device.

19. The air purification system according to claim 18 , wherein:
the plurality air purification devices are configured to automatically generate a plurality of movement paths;
the plurality of movement paths are configured to avoid occupants or to be adjacent to the occupants based on preferences or habits of the occupants; and
at least one of the plurality of air purification devices is integrated with a floor cleaner configured to vacuum or wet-clean a floor on at least one of the plurality of movement paths.
