Automatic reminder method and device for vehicle air conditioner filter element replacement

Abstract

The invention provides a method for automatically reminding replacement of an automobile air conditioner filter element. The method comprises the following steps: calculating the voltage difference of a driving circuit of a blower before and after airflow passes through the automobile air conditioner filter element, wherein the voltage difference is named as a first voltage difference; and comparing the first voltage difference with a voltage difference threshold, and sending automobile air conditioner filter element replacement reminding information if the first voltage difference is greater than a voltage difference threshold. According to the method provided by the embodiment of the invention, the voltage difference of the driving circuit of the air conditioner blower before and after airflow passes through the automobile air conditioner filter element is calculated and automobile air conditioner filter element replacement reminding information is sent if the first voltage difference is greater than the voltage difference threshold, so that compared with the prior art, the method has the advantages that the automobile air conditioner filter element replacement reminding information can be sent under conditions of not increasing the cost and volume of an automobile air conditioner, and the sent automobile air conditioner filter element replacement reminding information is accurate and timely, therefore, the filtration effect of air in an automobile is ensured, and economic waste caused by replacing the air conditioner filter element uniformly according to time due to automobile air conditioner use frequency difference of users is avoided.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an automatic prompting method and device for replacing a vehicle-mounted air-conditioning filter element. Background technique [0002] At present, the ambient air quality is worrying, and the interior of the vehicle is a closed environment, and the air flow is not smooth. Therefore, in order to ensure the air quality in the vehicle, more and more vehicle air conditioners are installed in various vehicles. The car air conditioner can filter the debris, impurities, tiny particles, pollen, bacteria, industrial waste gas and dust in the air, so as to improve the cleanliness of the air in the car, provide a good air environment for the passengers in the car, and protect the safety of the people in the car. Healthy body. [0003] Due to the limited dust holding capacity of the air conditioning filter, when the dust holding capacity of the air conditioning filter is saturated, the car ...

Problems solved by technology

[0004] However, due to the difference in the mileage of the vehicle and the frequency of use of the air conditioner, replacing the air conditioner filter by timing may cause a certain amount of waste, and users generally do not clearly remember the time to replace the air conditioner filter; The way of judging and prompting the user to replace the car air conditioning filter element due to the change of wind resistance not only increases the cost of the car air conditioner, but also increases the volume of the car air conditioner, making the space in the car narrower
