The value is compared with the first rotation speed value. If the first rotation speed value is greater than the preset rotation speed value, it means that the first rotation speed value of the fan 11 is abnormal, and starts to count the second time. On the contrary, if the first rotation speed value is smaller than the preset rotation speed value When the value of the first rotational speed of the fan 11 is normal, continue to count the first time, and at the first preset time, obtain the rotational speed value again and compare it with the preset rotational speed value, that is, the rotational speed of the fan 11 is continuously monitored for a fixed time. value.

If the first speed value is greater than 3700RPM, the second time is counted, and the second time reaches the second preset time. When the time is set, that is, 1 minute later, the second rotational speed value of the fan 11 is obtained again. If the second rotational speed value is still greater than 3700 RPM, it means that the blocking rate of the filter device 12 reaches 90%, and a prompt to replace the lamp is activated.

When the fan of the air purifying device 1 is turned on at a high-speed wind speed of 5000 RPM, the preset rotational speed is 5400 RPM and the preset second time is 1 minute. Therefore, the first time is counted up to the preset first time, such as 30 minutes, that is, every Obtain the first rotational speed value of the fan 11 within 30 minutes. If the first rotational speed value is greater than 5400 RPM, count the second time, and when the second time reaches the second preset time, that is, 1 minute later, obtain the second rotational speed of the fan 11 again. The rotation speed value, if the second rotation speed value is still greater than 5400RPM, it means that the blockage rate of the filter device 12 reaches 90%, and a prompt to replace the light signal is activated.

Step ST25: When the arithmetic processing module compares the second temperature value according to the first preset temperature value and the second preset temperature value, the second temperature value is greater than the first preset temperature value or the temperature value When the temperature is less than the second preset temperature value, the operation processing module stops working.

Also reviewing the second figure, the optimized filter replacement system of the present invention further includes a temperature sensing device S2, which is electrically connected to the computing processing module P.

As shown in step ST19, the temperature sensing device S2 can further sense the ambient temperature around the air purification device 1 to obtain a first temperature value, and then as shown in step ST21, when the arithmetic processing module P according to the first preset When the temperature value and the second preset temperature value are compared to the first temperature value, if the first temperature value is greater than the first preset temperature value or the first temperature value is less than the second preset temperature, a fourth time is counted.

As shown in step ST23, when the arithmetic processing module P determines that the fourth time reaches the fifth preset time, the temperature sensing device S2 senses the ambient temperature and obtains the second temperature value, and continues as in step ST25, when the arithmetic processing module P When group P compares the second temperature value according to the first preset temperature value and the second preset temperature value, if the second temperature value is greater than the first preset temperature value or the first temperature value is less than the second preset temperature, then It means that the ambient temperature of the air purification device 1 is bad, and the operation processing module P stops operation, that is, when the operation processing module P senses the abnormal environment through the temperature sensing device S2, it also detects the duration of its inclination. When the preset time is reached, the operation of the air purification device 1 is suspended to avoid danger.

In order to express the method flow of the present invention more clearly, an example will be given to illustrate. The temperature limit of the air purification device 1 is to protect the electronic components and the battery, and the charging and discharging under the high temperature or low temperature conditions of the surrounding environment will seriously affect the battery life. As set, in this embodiment, the first preset temperature value is 60 degrees, the second preset temperature is -5 degrees, and the fourth preset time is 5 seconds as an example, when the temperature sensing device S2 measures the first temperature When the value is greater than 60 degrees or less than -5 degrees, count the fourth time, and when the fourth time reaches the fifth preset time, that is, 5 seconds, measure the second temperature value again, if the second temperature value is still greater than 60 degrees When the temperature is less than -5 degrees, it means that the air purification device 1 is placed abnormally and stops working.
