Abstract
A method for detecting filter status is applicable to an electronic device including a filter, and the method includes the following steps. In response to activation of the electronic device, timing is started and an accumulated operating time is obtained. In response to the accumulated operating time being greater than or equal to a time threshold value, a level of dirtiness of the filter is detected through an optical sensing element. The time threshold value is adjusted according to the level of dirtiness of the filter. A notification related to the filter is provided according to the level of dirtiness of the filter.
Claims18
A method for detecting filter status applicable to an electronic device having a filter, comprising:
- starting timing and obtaining an accumulated operating time in response to activation of the electronic device;
- detecting a level of dirtiness of the filter through an optical sensing element in response to the accumulated operating time being greater than or equal to a time threshold value;
- adjusting the time threshold value according to the level of dirtiness of the filter;
- and
- providing a notification related to the filter according to the level of dirtiness of the filter,
- wherein the step of adjusting the time threshold value according to the level of dirtiness of the filter comprises:
- maintaining the time threshold value at a first value in response to determining the level of dirtiness of the filter being a first level;
- and
- increasing the time threshold value from the first value to a second value according to a first weight corresponding to a second level in response to determining the level of dirtiness of the filter being the second level.
An electronic device, comprising:
- a filter;
- an optical sensing element;
- a human-machine interface device;
- and
- a processor coupled to the optical sensing element and the human-machine interface device and configured to:
- start timing and obtain an accumulated operating time in response to activation of the electronic device,
- detect a level of dirtiness of the filter through an optical sensing element in response to the accumulated operating time being greater than or equal to a time threshold value,
- adjust the time threshold value according to the level of dirtiness of the filter,
- provide a notification related to the filter according to the level of dirtiness of the filter through the human-machine interface device,
- maintain the time threshold value at a first value in response to determining the level of dirtiness of the filter being a first level, and
- increase the time threshold value from the first value to a second value according to a first weight corresponding to a second level in response to determining the level of dirtiness of the filter being the second level.
