Abstract

A method for a device to acquire air quality, includes: controlling a fan to rotate; measuring air quality by an air-quality detector; and generating air-quality information according to a measurement result of the air-quality detector.

First claim

What is claimed is:

1 . A method for a device to acquire air quality, comprising:
controlling a fan to rotate; measuring air quality by an air-quality detector; and generating air-quality information according to a measurement result of the air-quality detector.

2 . The method according to claim 1 , wherein the measuring of the air quality by the air-quality detector comprises:
detecting whether a rotation time of the fan reaches a predetermined length of time; and measuring the air quality through the air-quality detector if the rotation time reaches the predetermined length of time.

3 . The method according to claim 1 , wherein the controlling of the fan to rotate comprises:
detecting whether an air-flowing speed in an environment surrounding the device reaches a predetermined speed; and controlling the fan to rotate if the air-flowing speed does not reach the predetermined speed.

4 . The method according to claim 1 , further comprising:
receiving a trigger signal sent by a mobile terminal, the trigger signal being configured to trigger the measurement of the air-quality; and controlling the fan to rotate according to the trigger signal.

5 . The method according to claim 4 , further comprising at least one of:
sending the air-quality information to the mobile terminal for displaying; sending the air-quality information to a server, the server being configured to send the air-quality information to the mobile terminal for displaying; or sending the air-quality information to a gateway device, the gateway device being configured to send the air-quality information to the mobile terminal for displaying.

6 . The method according to claim 1 , further comprising:
detecting whether a predetermined time is reached, the predetermined time being one of a plurality of times at a predetermined time interval, or a time set by a user; and controlling the fan to rotate if the predetermined time is reached.

7 . The method according to claim 6 , further comprising:
sending the air-quality information to at least one of a server or a gateway device, the at least one of the server or the gateway device being configured to:
receive from a mobile terminal a trigger signal for displaying air-quality information; and
send to the mobile terminal most recently received air-quality information or all historically received air-quality information.

8 . A device for acquiring air quality, comprising:
a processor; and a memory for storing instructions executable by the processor; wherein the processor is configured to perform: controlling a fan to rotate; controlling an air-quality detector to measure air quality; and generating air-quality information according to a measurement result of the air quality detector.

9 . The device according to claim 8 , wherein the processor is further configured to perform:
detecting whether a rotation time of the fan reaches a predetermined length of time; and controlling the air quality detector to measure the air quality if the rotation time reaches the predetermined length of time.

10 . The device according to claim 8 , wherein the processor is further configured to perform:
detecting whether an air-flowing speed in an environment surrounding the device reaches a predetermined speed; and controlling the fan to rotate if the air-flowing speed does not reach the predetermined speed.

11 . The device according to claim 8 , wherein the processor is further configured to perform:
receiving a trigger signal sent by a mobile terminal, the trigger signal being configured to trigger the measurement of the air quality; and controlling the fan to rotate according to the trigger signal.

12 . The device according to claim 11 , wherein the processor is further configured to perform at least one of:
sending the air-quality information to the mobile terminal for displaying; sending the air-quality information to a server, the server being configured to send the air-quality information to the mobile terminal for displaying; and sending the air-quality information to a gateway device, the gateway device being configured to send the air-quality information to the mobile terminal for displaying.

13 . The device according to claim 8 , wherein the processor is further configured to perform:
detecting whether a predetermined time is reached, the predetermined time being one of a plurality of times at a predetermined time interval, or a time set by a user; and controlling the fan to rotate if the predetermined time is reached.

14 . The device according to claim 13 , wherein the processor is further configured to perform:
sending the air-quality information to at least one of a server or a gateway device, the at least one of the server or the gateway device being configured to:
receive from a mobile terminal a trigger signal for displaying air-quality information; and
send to the mobile terminal most recently received air-quality information or all historically received air-quality information.

15 . A non-transitory computer-readable storage medium storing instructions that, when executed by a processor of a device, cause the device to perform a method for acquiring air quality, the method comprising:
controlling a fan to rotate; measuring air quality by an air-quality detector; and generating air-quality information according to a measurement result of the air quality detector.

16 . The medium according to claim 15 , wherein the measuring of the air quality by the air-quality detector comprises:
detecting whether a rotation time of the fan reaches a predetermined length of time; and measuring the air quality through the air-quality detector if the rotation time reaches the predetermined length of time.

17 . The medium according to claim 15 , wherein the controlling of the fan to rotate comprises:
detecting whether an air-flowing speed in an environment surrounding the device reaches a predetermined speed; and controlling the fan to rotate if the air-flowing speed does not reach the predetermined speed.

18 . The medium according to claim 15 , wherein the method further comprises:
receiving a trigger signal sent by a mobile terminal, the trigger signal being configured to trigger the measurement of the air-quality; and controlling the fan to rotate according to the trigger signal.

19 . The medium according to claim 18 , wherein the method further comprises at least one of:
sending the air-quality information to the mobile terminal for displaying; sending the air-quality information to a server, the server being configured to send the air-quality information to the mobile terminal for displaying; and sending the air-quality information to a gateway device, the gateway device being configured to send the air-quality information to the mobile terminal for displaying.

20 . The medium according to claim 15 , wherein the method further comprises:
detecting whether a predetermined time is reached, the predetermined time being one of a plurality of times at a predetermined time interval, or a time set by a user; and controlling the fan to rotate if the predetermined time is reached.
