Because the first gear, the second gear and the third gear are higher in gear and higher in wind speed, users feel uncomfortable when the air is blown for a long time, and the second phase is started after the first phase is operated for a first time. The first gear is higher than the third gear in the first stage, and the third gear is higher than the second gear, so that the gear is firstly reduced from the first gear to the second gear, then increased from the second gear to the third gear, then increased from the third gear to the first gear, and the gear is more fit with the transformation form of natural wind. The duration of the second stage is the second duration, the sequence of gear changes is that the gear changes are operated in the fourth gear, then in the fifth gear and then in the sixth gear, and the first stage is entered again after the second preset duration is circulated. In the second stage, the fourth gear is higher than the sixth gear, and the sixth gear is higher than the fifth gear, so that the gear is firstly reduced from the fourth gear to the fifth gear, then increased from the fifth gear to the sixth gear, then increased from the sixth gear to the fourth gear, and the natural wind conversion form is more attached.

In one embodiment, the fourth gear is equal to the preset gear.
In this embodiment, if the current gear is higher than the fourth gear, which means that the current ambient temperature is higher, and therefore, the gear that the user just starts to select is higher, the first phase and the second phase are cycled, the duration of the first phase is a first period, the sequence of gear changes is to operate in the first gear, then in the second gear, then in the third gear, and so forth, and the first period is cycled. Because the first gear, the second gear and the third gear are higher in gear and higher in wind speed, users feel uncomfortable when the air is blown for a long time, and the second phase is started after the first phase is operated for a first time. The first gear is higher than the third gear in the first stage, and the third gear is higher than the second gear, so that the gear is firstly reduced from the first gear to the second gear, then increased from the second gear to the third gear, then increased from the third gear to the first gear, and the gear is more fit with the transformation form of natural wind.

Of course, in other alternative embodiments, the preset gear may be higher than the fourth gear.
In one embodiment, the preset gear is 4.
Since a conventional fan has 8 gears, it may be appropriate to select 4 gears as the preset gears.
Specifically, if the current gear is higher than 4 gears, which means that the current environmental temperature is higher, so that the gear which is just selected by the user is higher, the first stage and the second stage are circulated, the duration of the first stage is a first period, the sequence of gear change is to operate in the first gear, then operate in the second gear and then operate in the third gear, and the first period is circulated. Because the first gear, the second gear and the third gear are higher in gear and higher in wind speed, users feel uncomfortable when the air is blown for a long time, and the second phase is started after the first phase is operated for a first time. The first gear is higher than the third gear in the first stage, and the third gear is higher than the second gear, so that the gear is firstly reduced from the first gear to the second gear, then increased from the second gear to the third gear, then increased from the third gear to the first gear, and the gear is more fit with the transformation form of natural wind. The duration of the second stage is the second duration, the sequence of gear changes is that the gear is operated in 4 th gear, then in fifth gear and then in sixth gear, and the first stage is entered again after the second preset duration is circulated. In the second stage, the 4 th gear is higher than the sixth gear, and the sixth gear is higher than the fifth gear, so that the gear is firstly reduced from the 4 th gear to the fifth gear, then increased from the fifth gear to the sixth gear, then increased from the sixth gear to the 4 th gear, and the gear is more fit with the transformation form of natural wind. The first stage and the second stage are circulated, the wind speed is continuously changed, and the user feel more comfortable.
If the current gear is lower than 4 gears, the current environment temperature is not very high, so that the current environment temperature is cyclically operated according to the sequence of 4 gears, the fifth gear and the sixth gear, the gear is firstly reduced from the 4 gears to the fifth gear, then is increased from the fifth gear to the sixth gear, and then is increased from the sixth gear to the 4 gears, and the current environment temperature is more suitable for the transformation form of natural wind, so that the body feeling of a user is more comfortable.
Of course, in other alternative embodiments, the preset gear may be 5 when the fan has more gears.
In one embodiment, the first gear is 7, the second gear is 5, the third gear is 6, the fifth gear is 2, and the sixth gear is 3.
In this embodiment, if the current gear is higher than 4, it indicates that the current ambient temperature is higher, so that the gear that the user just begins to select is higher, the first phase and the second phase are cycled, the duration of the first phase is a first period, the sequence of gear changes is to operate in 7 th gear, then in 5 th gear, then in 6 th gear, and so on, thus cycling for the first period. Because the gears of 7, 5 and 6 are higher, the wind speed is higher, and the long-time blowing can cause uncomfortable feeling to users, so that the first stage is operated for a first time and then the second stage is started. In the first stage, 7 th gear is higher than 6 th gear and 6 th gear is higher than 5 th gear, so that the gear is firstly reduced from 7 th gear to 5 th gear, then increased from 5 th gear to 6 th gear, then increased from 6 th gear to 7 th gear, and the gear is more fit with the transformation form of natural wind. The duration of the second stage is the second duration, the sequence of gear change is that the gear is operated at 4 th gear, then at 2 nd gear and then at 3 rd gear, and the first stage is entered again after the second preset duration is circulated. In the second stage, the 4 th gear is higher than the 3 rd gear and the 3 rd gear is higher than the 2 nd gear, so that the gear is firstly reduced from the 4 th gear to the 2 nd gear, then is increased from the 2 nd gear to the 3 rd gear, then is increased from the 3 rd gear to the 4 th gear, and is more fit with the transformation form of natural wind. The first stage and the second stage are circulated, the wind speed is continuously changed, and the user feel more comfortable.
If the current gear is lower than 4 grades, the current environment temperature is not very high, so that the current environment temperature is circularly operated according to the sequence of 4 grades, 2 grades and 3 grades, the gear is firstly reduced from 4 grades to 2 grades, then is increased from 2 grades to 3 grades, then is increased from 3 grades to 4 grades, and the current environment temperature is more suitable for the transformation form of natural wind, so that the user feel more comfortable.
It should be noted that "1 st gear" to "6 th gear" refer to the actual gear of the physical electric fan itself.
In one embodiment, the first time period is less than or equal to 20 minutes, and/or the second time period is less than or equal to 10 minutes.
In this embodiment, when the first stage is operated, the gear is relatively high, the wind speed is relatively high, and the user is uncomfortable when the user continuously blows for 20 minutes under the condition of relatively high wind speed, so that the first time length is less than or equal to 20 minutes, and then the second stage is operated, and the user feel more comfortable. The second period of time for the second phase operation is shorter because the current ambient temperature is higher.
In particular, in one embodiment, the first time period is equal to 20 minutes and the second time period is equal to 10 minutes.
In this embodiment, if the current gear is higher than 4, it means that the current ambient temperature is higher, so that the gear that the user just begins to select is higher, the cycle is divided into a first stage and a second stage, the duration of the first stage is 20min, the sequence of gear changes is that 7 th, then 5 th, then 6 th are operated, and the cycle is 20min. Because the gears of 7, 5 and 6 are higher, the wind speed is higher, and the user can feel uncomfortable when blowing for a long time, the device enters the second stage after 20 minutes of operation in the first stage. In the first stage, 7 th gear is higher than 6 th gear and 6 th gear is higher than 5 th gear, so that the gear is firstly reduced from 7 th gear to 5 th gear, then increased from 5 th gear to 6 th gear, then increased from 6 th gear to 7 th gear, and the gear is more fit with the transformation form of natural wind. The duration of the second stage is 10min, the sequence of gear change is that the gear is operated at 4 th gear, then at 2 nd gear and then at 3 rd gear, and the first stage is entered again after the second preset duration is circulated. In the second stage, the 4 th gear is higher than the 3 rd gear and the 3 rd gear is higher than the 2 nd gear, so that the gear is firstly reduced from the 4 th gear to the 2 nd gear, then is increased from the 2 nd gear to the 3 rd gear, then is increased from the 3 rd gear to the 4 th gear, and is more fit with the transformation form of natural wind. The first stage and the second stage are circulated, the wind speed is continuously changed, and the user feel more comfortable.
Specifically, referring to fig. 2, when the ambient temperature is 28 ℃, the electric fan is operated under different gear conditions, the thermal acceptability value of the user is continuously reduced, and particularly, after the electric fan is operated for 20min in 7 th gear and 8 th gear, the user can not receive the wind blowing 7 th gear and 8 th gear, so that the first time period is set to be 20min more appropriately.
Referring to fig. 3, when the ambient temperature is 30 ℃, the electric fan is operated in different gear, the thermal acceptability value of the user is continuously reduced, and because the ambient temperature is higher, the thermal acceptability value of the user is reduced relatively quickly when the user operates in a low gear such as 1 gear, 2 gear and 3 gear, and is reduced to 0 between 10 min and 15min, so that the second time period is more suitable than 10 min, and the thermal acceptability value of the user is reduced to 0 after the 7 gear and 8 gear are approximately operated for 20min, so that the first time period is more suitable to be set to 20 min.
Referring to fig. 4, a thermal sensation voting was performed for the scheme of this example, and the results are shown in fig. 4, wherein 3 represents heat, 2 represents warmth, 1 represents slightly warmth, 0 represents no coldness or no warmth, -1 represents little coolness, -2 represents coolness, -3 represents coolness. According to the voting result, the experience of the experimenter on the environment is hot at the beginning, and becomes cold and hot after one period is finished, so that the expected result is met.
In one embodiment, cycling in the order of the first gear, the second gear, and the third gear includes:
and circularly running according to the sequence of respectively running the first gear, the second gear and the third gear for a first preset time period.

In particular, in one embodiment, the first preset duration and/or the second preset duration is 20s.
In this embodiment, if the current gear is higher than 4, it means that the current ambient temperature is higher, so that the gear that the user just starts to select is higher, the cycle is divided into a first stage and a second stage, the duration of the first stage is 20min, the sequence of gear change is that the gear is operated for 20s at 7 th, then for 20s at 5 th, then for 20s at 6 th, and the cycle is thus 20min. Because the gears of 7, 5 and 6 are higher, the wind speed is higher, and the user can feel uncomfortable when blowing for a long time, the device enters the second stage after 20 minutes of operation in the first stage. In the first stage, 7 th gear is higher than 6 th gear and 6 th gear is higher than 5 th gear, so that the gear is firstly reduced from 7 th gear to 5 th gear, then increased from 5 th gear to 6 th gear, then increased from 6 th gear to 7 th gear, and the gear is more fit with the transformation form of natural wind. The duration of the second stage is 10min, the sequence of gear change is that the gear is firstly operated for 20s in 4 th gear, then operated for 20s in 2 nd gear and then operated for 20s in 3 rd gear, and the first stage is entered again after the second preset time period is circulated. In the second stage, the 4 th gear is higher than the 3 rd gear and the 3 rd gear is higher than the 2 nd gear, so that the gear is firstly reduced from the 4 th gear to the 2 nd gear, then is increased from the 2 nd gear to the 3 rd gear, then is increased from the 3 rd gear to the 4 th gear, and is more fit with the transformation form of natural wind. The first stage and the second stage are circulated, the wind speed is continuously changed, and the user feel more comfortable.
If the current gear is lower than 4 grades, the current environment temperature is not very high, so that the current environment temperature is circularly operated according to the sequence of 4 grades of operation 20s, 2 grades of operation 20s and 3 grades of operation 20s, the gear is firstly reduced from 4 grades to 2 grades, then is increased from 2 grades to 3 grades, then is increased from 3 grades to 4 grades, and is more fit with the transformation form of natural wind, so that the user feel more comfortable.
Of course, in other alternative embodiments, the first preset duration and the second preset duration may be 10s.
According to an embodiment of the present invention, a third aspect provides a control device of an electric fan, including:
the judging module is used for judging whether the current gear is higher than a preset gear after entering a natural wind mode;
the first execution module is used for circularly running according to the sequence of a first stage and a second stage when the current gear is higher than a preset gear, wherein the first stage comprises circularly running for a first duration according to the sequence of a first gear, a second gear and a third gear, the second stage comprises circularly running for a second duration according to the sequence of a fourth gear, a fifth gear and a sixth gear, the first gear is higher than the third gear, the third gear is higher than the second gear, the second gear is higher than the preset gear, the fourth gear is higher than the sixth gear, the sixth gear is higher than the fifth gear, and the fourth gear is equal to or lower than the preset gear;
And the second execution module is used for circularly running according to the sequence of the fourth gear, the fifth gear and the sixth gear when the current gear is equal to or lower than the preset gear.

Because the first gear, the second gear and the third gear are higher in gear and higher in wind speed, users feel uncomfortable when the air is blown for a long time, and the second phase is started after the first phase is operated for a first time. The first gear is higher than the third gear in the first stage, and the third gear is higher than the second gear, so that the gear is firstly reduced from the first gear to the second gear, then increased from the second gear to the third gear, then increased from the third gear to the first gear, and the gear is more fit with the transformation form of natural wind. The duration of the second stage is the second duration, the sequence of gear changes is that the gear changes are operated in the fourth gear, then in the fifth gear and then in the sixth gear, and the first stage is entered again after the second preset duration is circulated. In the second stage, the fourth gear is higher than the sixth gear, and the sixth gear is higher than the fifth gear, so that the gear is firstly reduced from the fourth gear to the fifth gear, then increased from the fifth gear to the sixth gear, then increased from the sixth gear to the fourth gear, and the natural wind conversion form is more attached. The first stage and the second stage are circulated, the wind speed is continuously changed, and the user feel more comfortable.
If the current gear is lower than the preset gear, the current environment temperature is not very high, so that the gear is cyclically operated according to the sequence of the fourth gear, the fifth gear and the sixth gear, the gear is firstly reduced from the fourth gear to the fifth gear, then is increased from the fifth gear to the sixth gear, and then is increased from the sixth gear to the fourth gear, and the change form of natural wind is attached, so that the user feel more comfortable.

Because the first gear, the second gear and the third gear are higher in gear and higher in wind speed, users feel uncomfortable when the air is blown for a long time, and the second phase is started after the first phase is operated for a first time. The first gear is higher than the third gear in the first stage, and the third gear is higher than the second gear, so that the gear is firstly reduced from the first gear to the second gear, then increased from the second gear to the third gear, then increased from the third gear to the first gear, and the gear is more fit with the transformation form of natural wind. The duration of the second stage is the second duration, the sequence of gear changes is that the gear changes are operated in the fourth gear, then in the fifth gear and then in the sixth gear, and the first stage is entered again after the second preset duration is circulated. In the second stage, the fourth gear is higher than the sixth gear, and the sixth gear is higher than the fifth gear, so that the gear is firstly reduced from the fourth gear to the fifth gear, then increased from the fifth gear to the sixth gear, then increased from the sixth gear to the fourth gear, and the natural wind conversion form is more attached. The first stage and the second stage are circulated, the wind speed is continuously changed, and the user feel more comfortable.
If the current gear is lower than the fourth gear, the current environment temperature is not very high, so that the gear is cyclically operated according to the sequence of the fourth gear, the fifth gear and the sixth gear, the gear is firstly reduced from the fourth gear to the fifth gear, then is increased from the fifth gear to the sixth gear, and then is increased from the sixth gear to the fourth gear, and the change form of natural wind is attached, so that the user feel more comfortable.
