Is the difference between the durations less than or equal to the preset threshold? If so, a reminder message will be output to let the user know in time that the service life of the dehumidification module is about to be exhausted, so that the dehumidification module can be replaced in a timely manner so that the updated dehumidification module can continue It plays a dehumidifying role, improves the user experience, and improves the intelligence level of the fresh air fan.

In one embodiment of the present invention, the air parameters may include air intake volume and/or air humidity. The steps to obtain the air parameters of the air that needs to enter the fresh air fan according to the start instruction may include:

Obtain the unit air intake volume and/or unit air humidity corresponding to the preset unit time according to the opening command.

In this embodiment, the air parameters may also include air pollution index, temperature, etc. Different air inlet volumes and different air humidity will have different losses on the dehumidification module. Obtain the unit air inlet volume and/or unit air humidity corresponding to the preset unit time, that is, divide the air inlet volume and/or air humidity into multiple sections according to the preset unit time to ensure the unit air inlet volume and unit air in each section Humidity stability. In addition, the outdoor air humidity can be obtained through the network, and then the unit air humidity can be obtained. Of course, the outdoor air humidity can also be obtained through the humidity measuring device. When obtaining the unit air inlet volume, the unit air inlet volume can be obtained based on the air volume set on the fresh air fan.

In one embodiment of the present invention, the step of obtaining the unit loss time corresponding to the preset unit time based on the unit air intake volume and/or unit air humidity may include:

Match the unit air inlet volume and/or unit air humidity with the preset unit loss time length comparison table; wherein the unit loss time length comparison table includes multiple different unit air inlet volume ranges and/or unit air humidity ranges of preset unit time lengths The corresponding unit loss time;

Determine the unit air volume range and/or unit air humidity range to which the unit air volume and/or unit air humidity belongs, thereby obtaining the unit loss time corresponding to the preset unit time.

In this embodiment, the unit loss time corresponding to multiple different unit air volume ranges and/or unit air humidity ranges of preset unit time included in the unit loss time comparison table can be obtained through a large number of experiments. In the unit loss time comparison table, the unit air humidity range and the unit air inlet volume range can be a group, that is, the unit air humidity range and the unit air inlet volume range can correspond to the same unit loss time. Match the unit air inlet volume and unit air humidity with the preset unit loss time comparison table to determine the unit air inlet volume range and unit air humidity range to which the unit air inlet volume and unit air humidity belong, thereby obtaining the unit loss corresponding to the preset unit time period.

In one embodiment of the present invention, the preset unit duration is any value between 1-4 hours; and/or

The size of the preset unit time is inversely proportional to the amount of air intake and/or air humidity.

In this embodiment, specifically, for example, the preset unit duration may be 2 hours or 3 hours, etc. Because the air humidity and air inlet volume may change, if the preset unit time is too large, the unit air inlet volume and unit air humidity obtained may be inaccurate. If the preset unit time is too small, the unit air inlet volume obtained may be inaccurate. There are too many data and unit air humidity, which increases unnecessary calculations. Setting the preset unit duration to any value between 1 and 4 hours can avoid these problems. In addition, the greater the values of air intake volume and/or air humidity, the faster the life of the dehumidification module will be lost. When the values of air inlet volume and/or air humidity are large, the total loss time of the dehumidification module needs to be obtained as soon as possible. Therefore, the preset unit time needs a smaller value, that is, the size of the preset unit time is related to the inlet air volume and/or The air humidity is inversely proportional, and the total loss of the dehumidification module can be obtained as quickly as possible.

Get the signal that the dehumidification module is updated;

Resets the total loss duration to 0.

In this embodiment, a signal that the dehumidification module is updated is obtained, and the total loss duration is reset to 0, so that the total loss duration of the updated dehumidification module can be re-calculated.

In one embodiment of the present invention, the step of obtaining a signal that the dehumidification module is updated may include:

The signal fed back by the terminal device in response to the reminder information is obtained as a signal that the dehumidification module is updated.

In this embodiment, the signal fed back by the terminal device in response to the reminder information is obtained as the signal that the dehumidification module is updated.
