Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
Fig. 1 is a schematic flow chart of a method for reminding replacement of a filter screen of an air purifier according to an embodiment of the present invention.
As shown in fig. 1, the method of the present embodiment includes:
s11: acquiring air outlet information of an air outlet when the air purifier operates;
further, the air outlet information of the air outlet may be the air speed of the air outlet; or, the air quality of the air outlet.
S12: judging whether the filter screen needs to be replaced or not according to the air outlet information of the air outlet;
further, when dust on the filter screen is more, the air speed of the air outlet is too low or the air quality of the air outlet is poor, the filter screen is judged to need to be replaced;
otherwise, judging that the filter screen does not need to be replaced
S13: and sending out replacement reminding information when the filter screen is judged to need to be replaced.
The method for reminding the replacement of the filter screen of the air purifier can judge whether the filter screen needs to be replaced according to the actual condition of the filter screen on the air purifier, and solves the problem that a countdown method is unreasonable for reminding a user of replacing the filter screen in the prior art; meanwhile, the waste of the filter screen caused by insufficient use of the filter screen due to frequent replacement of the filter screen can be avoided.
Fig. 2 is a schematic flow chart of a method for reminding replacement of a filter screen of an air purifier according to a second embodiment of the present invention.
As shown in fig. 2, the method of the present embodiment includes:
s21: acquiring the initial wind speed of the air outlet when the air purifier is used for the first time, and storing the initial wind speed;
specifically, the air purifier is generally provided with a plurality of gears, and when the air purifier is used for the first time, the wind speed of the air outlet of the air purifier at each gear is recorded, namely the initial wind speed, and the initial wind speed is stored;
s22: acquiring air outlet information of an air outlet when the air purifier operates;
s23: judging whether the filter screen needs to be replaced or not according to the air outlet information of the air outlet;
further, the basis is judged according to the air-out information of air outlet whether the filter screen needs to be changed, include:
calculating a ratio between the current wind speed and the initial wind speed;
and judging whether the filter screen needs to be replaced or not according to the ratio.
Specifically, air purifier includes at least one gear, then the ratio is at least one, and every ratio is the ratio between the current wind speed of same gear and the initial wind speed respectively, according to the ratio judgement the filter screen whether need change, include:
and when at least one of the ratios is smaller than or equal to a preset threshold value, judging that the filter screen needs to be replaced.
Further, the preset threshold is 60%.
S24: and sending out replacement reminding information when the filter screen is judged to need to be replaced.
In actual implementation, firstly, acquiring an initial wind speed of the air outlet when the air purifier is used for the first time, and storing the initial wind speed, wherein the air purifier is provided with n gears, which are recorded as 1, 2, 3, … and n gears, and wind speeds corresponding to the gears in the first use are respectively recorded as L1, L2, L3, … and Ln; after the air purifier used for a period of time, because the filter screen can pile up the dust through the use, influence the wind speed of air outlet department, at this moment, the wind speed that each gear corresponds is recorded as M1, M2, M3, …, Mn respectively. Setting j as any one of the n gears, and if Mj/Lj is less than or equal to 60%, judging that the filter screen needs to be replaced, so as to send a prompt message for replacing the filter screen to a user; and if Mj/Lj is more than 60%, judging that the filter screen does not need to be replaced.
It can be understood that, in the above process, the wind speed of each gear is determined, and in actual operation, the air flow of the air outlet at each gear may also be determined.
It should be noted that, in this embodiment, the value of the preset threshold is 60%, and when the method is actually used, the value of the preset threshold is not limited to be 60%. The value of the preset threshold value is determined according to a deep learning algorithm in combination with the actual use place of the equipment and the filter screen filtering effect expected by the user.
According to the reminding method for replacing the filter screen of the air purifier, whether the filter screen needs to be replaced or not is judged according to the air outlet information of the air outlet when the air purifier operates, and the method can ensure that reminding information for replacing the filter screen is sent in time when more dust is on the filter screen and air cannot be well purified; meanwhile, the waste of the filter screen caused by insufficient use of the filter screen due to frequent replacement of the filter screen can be avoided.
Fig. 3 is a schematic flow chart of a method for reminding replacement of a filter screen of an air purifier according to a third embodiment of the present invention.
As shown in fig. 3, the method of the present embodiment includes:
s31: acquiring air quality information of an air outlet when the air purifier operates;
s32: judging whether the filter screen needs to be replaced or not according to the air quality information of the air outlet;
further, the step S32 includes:
and when the air quality does not reach the standard, judging that the filter screen needs to be replaced.
