Problems solved by technology
The present invention designs an automobile air-conditioning air intake filter and its detection method that can automatically detect the filtering effect, and the technical problem it solves is that the cleaning or replacement of the existing automobile air-conditioning air intake filter can only be done by the driver and passengers. Judging by prediction and feeling cannot truly and accurately reflect the use status of the car air-conditioning air intake filter, nor can it protect the health of drivers and passengers in a timely manner

Embodiment Construction
[0030] Combine below Figure 1 to Figure 5 , the present invention is further described:
[0031] Such as figure 1 As shown, a car air-conditioning air intake filter that can automatically detect the filtering effect includes a filter core 1, and a detection sensor is arranged on the filter core 1, and the detection sensor sends the detected signal to the air conditioner the ECU.
[0032] Such as figure 2 As shown, the detection sensor is a wind speed detection sensor 2, and the wind speed detection sensor 2 is composed of an air inlet detection unit 21 and an air outlet detection unit 22. The air inlet detection unit 21 is located on the air inlet side 3 of the filter core 1, and the air outlet detection unit The unit 22 is located at the air outlet side 4 of the filter core 1 ; the air inlet detection unit 21 and the air outlet detection unit 22 form a groove structure 23 , and the wind speed detection sensor 2 is clamped and fixed in the groove structure 23 . The widt...

The invention relates to an automobile air conditioner inlet air filter capable of automatically detecting a filtering effect and a detection method thereof. The automobile air conditioner inlet air filter capable of automatically detecting the filtering effect comprises a filter element body (1), and is characterized in that the filter element body (1) is provided with a detection sensor, and a detected signal is sent to an electronic control unit (ECU) of an air conditioner by the detection sensor. According to the automobile air conditioner inlet air filter capable of automatically detecting the filtering effect and the detection method thereof, the air speed change or the pollution density value of air at an air outlet side is detected through the detection sensor, and once the filtering effect is detected to be reduced a lot, computation is performed through an internal procedure, and the signal is sent to the ECU of the air conditioner so as to remind a user of replacing a filter element in time.
Description
technical field [0001] The invention relates to an air inlet filter for an automobile air conditioner, in particular to an air inlet filter for an automobile air conditioner which can automatically detect the filtering effect. Background technique [0002] The current car air conditioning system generally adds a filter in the air inlet or HVAC, the purpose is to purify the air in the car, and block the polluted gas and other harmful substances outside from entering the car. [0003] However, the filter has been used for a long time, and the dust and harmful substances on it will affect the filtering effect of the air. In severe cases, the filtering effect on the air will be completely lost and cause blockage, which will seriously affect the use of the air conditioner. Therefore, it is usually the user who regularly replaces the core body according to the maintenance manual or performs maintenance after feeling that the air circulation is not smooth during use. At the same t...
