The filter 3 includes three partitions 31 which allow the internal area of the main body 1 to be divided into three and a central point of the partition 31 so as to be selectively fixed to the axis of the stepping motor 6. Any one of the conical filter cartridge 33 and the partitions 31 are installed in the horizontal direction from the upper surface portion between each of the partition walls 31 to be coupled to filter the impurities in the air introduced from the outside. It consists of a magnet (34) for use expiration notification is installed on the top edge of the bulkhead,

It is selectively operated by the magnet 34 in a state where it is installed on one side of the lid 4, causing the controller 8 to contaminate several conical filter cartridges 33 installed in the filter 3. A magnet sensor 5 for recognizing a state of being in a closed state;

It is selectively rotated in response to the output signal of the controller 8 in the state of being installed at the bottom of the main body 1 to generate rotational power to the rotating shaft 32 so that the filter 3 is rotated by a predetermined angle at a time. A stepping motor 6;

An air quantity detection sensor (7) installed on the outlet duct (41) of the lid (4) to detect the amount of air passing through the filter (3) as an electrical signal and output it to the controller (8);

Several conical filter cartridges 33 installed in the filter 3 by driving the stepping motor 6 by a certain angle in one direction whenever the air amount per unit volume detected by the air quantity detecting sensor 7 is equal to or less than a reference value. If the contaminated filter cartridge is located toward the outside air inlet 11 of the main body 1 and a predetermined output signal is inputted from the magnet sensor 5, a light signal is output to the filter replacement time notification lamp 9. A control unit 8 for making it;

Since several conical filter cartridges 33 installed in the filter 3 in the state of being installed inside the vehicle are all contaminated, the filter replacement time notification to be turned on when a predetermined output signal is generated from the control unit 8 It is characterized in that an additional lamp 9 is provided.

Referring to the operation and effect of the device of the present invention configured as described above are as follows.

First, in the present invention, the filter 3 itself, which is detachably installed into the cylindrical body 1 and filters out various impurities contained in the air introduced from the outside, does not form as one conventionally, but has an angle of 120 degrees. Three partitions 31 for dividing the internal area of the main body 1 into three, and a rotating shaft 32 fixedly installed at the center point of the partitions 31 and selectively coupled to the axis of the stepping motor 6, It is installed in the upper surface portion between each partition wall 31 in the horizontal direction to filter the impurities in the air introduced from the outside of the conical filter cartridge 33 and the upper edge of any one of the partition walls (31) Will be configured as a magnet 34 for use expiration notification.

Therefore, only one filter can be rotated properly so that the non-contaminated conical filter cartridge 33 can be located on the outside air inlet 11 side installed at one side of the main body 1. You can use (3) three times.

Of course, when the filter 3 is replaced, the magnet 34 for use expiration notification that is installed on the upper edge portion of one of the partition walls 31 is fixed to one side of the lid 4. In consideration of the rotation direction of the sensor 5 and the stepping motor 6, the position of the sensor 5 and the magnet sensor 5 must be accurately known and installed. All conical filter cartridges 33 can be used for external air filtering.

On the other hand, the filter 3 having the above-described configuration is mounted in the main body 1 so that the lid 4 is closed and the engine is started while the rotary shaft 32 is connected to the shaft of the stepping motor 6. When the controller 8 is placed, the air flow rate per unit volume of the filter 3 is measured by the air amount detection sensor 7 installed on the outlet duct 41 of the lid 4 as shown in FIG. It will continue to determine if it is above the prescribed value.

As a result, if the amount of air passing through the conical filter cartridge located at the outside air inlet 11 side of the main body 1 of the several conical filter cartridges 33 installed in the filter 3 is higher than the reference value, it is recognized as a normal state. If no output signal is generated but less than the reference value, it is determined that the corresponding conical filter cartridge is mistaken and generates a control signal for driving the stepping motor 6 by a certain angle in one direction.

Accordingly, the next conical filter cartridge, which is not contaminated, among the several conical filter cartridges 33 installed in the filter 3 is automatically rotated toward the external air inlet 11 of the main body 1, so that the filter 3 Even if it is not replaced, it is possible to continuously filter the outside air through the uncontaminated conical filter cartridge installed in the engine and supply it to the engine side.

On the other hand, by repeating the above process all three conical filter cartridges 33 installed in the filter 3 is continuously rotated in a contaminated state, so any one of the partition walls of the partition wall 31 of the filter (3) The use expiration notification magnet 34 installed at the upper edge portion is in contact with the magnet sensor 5 fixedly installed at one side of the lid 4 to output a predetermined output signal from the magnet sensor 5. Is generated, the driver 8 recognizes that the filter has to be replaced and outputs a lighting signal to the use expiration notification lamp 9 installed in the vehicle. By seeing the lighting condition of (9), it is possible to recognize the replacement time of the filter accurately, so that a new filter can be replaced in a short time.

As described above, according to the present invention, one air filter can be rotated according to the degree of contamination so that it can be used continuously for three times, thereby replacing one air filter while maintaining an appropriate environment of engine combustion conditions. Since the cycle can be greatly increased, the economic burden of the borrower can be greatly reduced, and it is a very useful invention that can solve the hassle caused by frequent filter changes.
