detailed description

In order to make the embodiments, technical solutions and advantages of the present invention more obvious, the technical solutions of the present invention will be described clearly and completely in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present invention, but not all Examples. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

Referring to FIG. 1, FIG. 1 is a main flowchart of a cleaning reminding method of a purification module according to an embodiment of the present invention. As shown in FIG. 1, the cleaning reminding method of the purification module of the present invention includes: S110, detecting the concentration value of PM2.5 in the air during the operation of the purification module; S120, obtaining the concentration value of PM2.5 from the first concentration value Time T taken to decrease to the second concentration value; S130. Determine whether to send a reminder message for cleaning and purification module according to the time T. It can be understood by those skilled in the art that assuming that the purification module purifies PM2.5 in the air from the first concentration value to the second concentration value every time, then in this process, the purification module purifies the PM2 in the air .5 The time T from the first concentration value to the second concentration value will vary with the cleanliness of the purification module. That is to say, with the use of the purification module, there will be more and more dust on the purification module, accordingly, the purification module is used to purify the PM2.5 in the air from the first concentration value to the second concentration value every time The time T will also increase. Therefore, according to the time T, the degree of cleanliness of the purification module can be determined, so as to determine whether to issue a reminder message for cleaning the purification module.

The first concentration value in the above is greater than the second concentration value. The first concentration value and the second concentration value may be set by those skilled in the art according to actual needs. For example, the first concentration value may be any value between 75-115. The second concentration value may be any value between 35 and 75. Specifically, the first concentration value may be set to 100, and the second concentration value may be set to 50. Those skilled in the art can also flexibly set other suitable first concentration values and second concentration values, which are not limited in the present invention.

Those skilled in the art understand that the unit of the air quality index PM2.5 is μg / m ³ , and the unit of the first concentration value and the second concentration value in the present invention is μg / m ³ .

The specific embodiments of the present invention will be further described below.

In step S130, it is determined according to the time T whether to issue a reminder message for cleaning the purification module. As an example, when T / t ≥ a preset value, a reminder message for cleaning the purification module is issued. Where t is the time it takes for the concentration value of PM2.5 in the air to decrease from the first concentration value to the second concentration value during the initial operation of the purification module. Specifically, t can be a preset standard time. In order to obtain a more accurate standard time t, run the purification module for the first time in an environment where the concentration of PM2.5 in the air is the first concentration, and record the air The time it takes for the concentration value of PM2.5 to decrease to the second concentration value is the standard time t.

Those skilled in the art can understand that with the use of the purification module, the dust on the purification module will also increase, and accordingly, the purification module purifies the PM2.5 in the air from the first concentration value to The time T used for the second concentration value will also increase, and the standard time t is the time it takes to purify the PM2.5 in the air from the first concentration value to the second concentration value when the purification module is first used. Therefore, once T exceeds t When it reaches a certain level, it can be judged that there is too much dust on the purification module, and a reminder message for cleaning the purification module can be issued.

As an example, the above preset value may be set to 4, that is, when T≥4t, that is, the current purification module reduces the PM2.5 concentration value in the air from the first concentration value to the second concentration value The time T is four times the standard time t. At this time, it means that too much dust on the purification module has affected the purification efficiency. Therefore, a reminder message for cleaning the purification module can be issued. Those skilled in the art can also set other suitable preset values according to actual application scenarios, for example, the preset value can be set to 3, 5, etc., or the preset value can be set to any value between 3-5, these Without departing from the scope of protection of the present invention.
