Description

[0001] The present invention relates to a sliding detachable air filter having an improved structure,

The present invention relates to an air filter inserted into an air cleaner for a vehicle, and more particularly, to an air filter which is inserted and fixed in a sliding manner through a side portion of an air cleaner other than a conventional upper and lower insertion type air filter, The present invention relates to a sliding detachable air filter for improving the adhesion force and fixing force between an air cleaner and an air filter as well as more easily inserting, fixing and separating the air filter.

Generally, an automobile is a mixture of fuel and air, and generates power. The fuel is supplied from the fuel tank to the engine, while air is supplied from the outside through the air cleaner and supplied to the engine. And then the suction, compression, explosion and exhaust strokes are repeated to obtain the power and propulsion of the automobile.

In this way, it is essential that the outside air is introduced into the automobile, and the inflow of the outside air is performed through the air cleaner provided in the engine room of the automobile. The air cleaner includes an air filter, And supplies purified air to the intake manifold.

In the air filter, a filter made of non-woven fabric or the like is folded and inserted in a zigzag form in the filter body, which is generally rectangular in plan view, so that the outside air flowing into the air cleaner is spread over a wide area And only the filtered air passing through the filter can be provided as an intake manifold.

At this time, when the air filter is used for a long time, a large amount of foreign matter is adsorbed toward the inflow side of the filter due to the filtering action of the outside air containing various foreign substances. As the adsorption amount of the foreign matter increases, The above-described air filter is a consumable material that needs to be replaced periodically.

In addition, in the above-described filter, normally, the upper side (lid) of the air cleaner is opened, the filter is placed in the filter, and the upper side (lid) of the air cleaner is closed to seal the inside.

However, since the air cleaner and the air filter mounting structure as described above can flow the air filter by the inflow air pressure, unfiltered air can be introduced due to the flow of the air filter, Noise is generated.

As a result, as disclosed in Korean Patent Laid-Open Nos. 10-2013-0061599 and 10-1318188, the air filter is slidably inserted into the air cleaner through the opened side by opening the side portion of the air cleaner The structure of the air cleaner has been revealed.

Since the air cleaner inserts the air filter through the side portion and rotates the handle provided on both sides of the inserted air filter so that the air filter can be closely fixed to the inside of the air cleaner, It is possible to prevent the unfiltered air from being supplied to the engine by eliminating the gap, and it is excellent in the close fixing force between the air cleaner and the air filter to prevent the air filter from flowing due to the vibration of the vehicle, It is known to be able to do.

However, the above-described sliding detachable air filter has a structure in which the air filter is raised inside the air cleaner by rotating the handle, and when the rotation amount of the handle is insufficient or abrasion of the cam portion occurs, the air filter is tightly fixed So that the unfiltered air flows into the engine of the vehicle through the generated gap.

That is, the handle has a structure in which a plurality of cam portions are formed, and the air filter is upwardly brought into close contact with the cam due to the eccentric amount of the cam portion by rotation of the handle. And when the load is continuously applied, the pressing and abrasion at the weakest corner of the cam occurs, and the force of pushing up the air filter is weakened, and eventually the air filter is lowered due to the abrasion of the cam portion, And a gap is generated.

In addition, the method of tightly fixing the air filter through the above-described handle rotation method is not suitable for the air cleaner of the vehicle in which the vibration is continuously generated. The vibrations of the vehicle are more frequent in the upward and downward directions than in the forward and backward directions When the vibration is applied to the handle of the air filter through the air cleaner, the fixed handle is rotated back to its original position due to the vibration, and the air filter is not tightly fixed in the inside of the air cleaner, And this causes the unfiltered air to flow into the engine.

Particularly, the air filter having the above-described rotary handle has to rotate the handle so that the handle is gripped by the user's finger at the side of the cramped air cleaner, and the handle is rotated so that at least two fingers are gripped It is very frequent that the handle can not be rotated sufficiently because the handle must be rotated by a strong force. Even when the air filter in such a state is to be replaced, the steering of the handle is very cumbersome and unnatural .

The present invention has been made to solve the problems described above. It is an object of the present invention to provide a sliding detachable air filter in which a separate detachable rod is coupled to both sides of a case of an air filter, The lifting and lowering supporting members for lifting and lowering the lifting and lowering rod of the lifting and lowering rod are respectively protruded and formed so that the lifting and lowering rod can be pushed or pulled in the forward and backward directions to be mounted or separated through the air filter ,

It is possible to solve the problem that the air filter is lowered from the inside of the air cleaner due to the vibration of the vehicle, and it is also possible to perform a stable filtering function for a long time because of its excellent durability as compared with the existing cam type. The present invention provides a sliding detachable air filter of an improved structure, which is characterized in that attachment and replacement of an air filter can be made very simple by pushing or pulling the air filter so that the air filter can be firmly fixed and separated.

According to an aspect of the present invention, there is provided a filter case, comprising: a filter case having an outward flange portion formed on an upper end thereof and having a packing groove formed on an upper surface of the flange portion; Wherein the filter case is moved up and down by moving the attaching / detaching rod, which is coupled to both sides of the filter case, before and after the filter case is lifted and lowered,

Wherein the filter case has an engaging support piece having guide grooves for allowing the detachable rod to move upward and downward in a state in which the detachable rod is inserted and a lifting and lowering support piece having an engaging groove into which the lifting / The filter case is lowered while the tip end of the guide groove is brought into close contact with the upper end of the attaching / detaching rod. When the lifting / lowering rod of the attaching / detaching rod is inserted into the fitting groove, And the filter case is raised by the outer diameter.

According to the present invention, not only is the intimate contact and fixation within the air cleaner achieved by pushing the detachable rod of the air filter, but also the detachment rod is pulled out and released from the air cleaner, And the abrasion of the lifting and lowering portion of the attaching / detaching rod does not occur due to the vibration of the vehicle, so that the air tightness of the air cleaner can be maintained. Therefore, And it is very economical because it is possible to realize cost reduction through mass production because of excellent assembly and productivity.

A packing groove 102 having a concave shape is formed on an upper surface of the flange portion 101, A packing 103 made of a soft elastic material is inserted so as to protrude from the upper surface of the flange portion 101. [

In the present invention, a separate detachable rod 10 (10 ') is coupled to the filter case 100, and as the detachable rod 10 (10') is moved in the forward and backward directions, 100 are raised or lowered in the upward and downward directions.

In order to realize this, each of the engaging and supporting pieces 110 and 110 'and the lifting and supporting pieces 120 and 120' are formed on both sides of the filter case 100 so as to protrude downward, 110 'are formed with flow grooves 111 which can flow upward and downward while the detachable rods 10, 10' are inserted inward. The elevating support pieces 120, 120 ' The lower ends of the coupling support pieces 110 and 110 'and the lower and upper ends of the lift supporting pieces 120 and 120' are formed to have the same height .

At this time, the flow grooves 111 and the fitting grooves 121 have a slightly narrower opening than the outer diameters of the detachable rods 10 and 10 'so that the flow grooves 111 and the fitting grooves 121 When the detachable rod 10 or 10 'is forcibly pressurized and coupled to the inside of the detachable rod 10 or 10', the flow of the detachable rod 10 or 10 ' Instead, they are not randomly separated until an artificial force acts.

The guide supporting pieces 130 and 130 'separated from each other are protruded downward between the coupling supporting pieces 110 and 110' and the elevating supporting pieces 120 and 120 ' Guide grooves 131 are formed in the guide support pieces 130 and 130 'so as to be able to move up and down with the detachable rods 10 and 10' inserted therein.

The attachment and detachment rods 10 and 10 'coupled to the respective support pieces are formed in the shape of long bars along the longitudinal direction of the filter case 100. The detachable rods 10 and 10' The elevating protrusions 11 and 11 'having an outer diameter larger than the outer diameter of the detachable rods 10 and 10' are formed in the pair of the elevating protrusions 11 and 11 ' 12 ', 12', 12 ', 12', 12 ', 12', 12 ', 12', 12 '

When the attachment and detachment rods 10 and 10 'are coupled to the filter case 100 and the attachment and detachment rods 10 and 10' are pushed upward from below the respective support pieces, And the insertion and removal rods 10 and 10 'are connected to the fitting groove 121 by the flow grooves 111 and the fitting grooves 121 So that they can move in the upward and downward directions.

The coupling supporting pieces 110 and 110 'and the elevating supporting pieces 120 and 120' are disposed apart from the outer side of the filter case 100 along the longitudinal direction. The elevating supporting pieces 120 and 120 ' Are respectively positioned at outer end portions of the filter case 100 and the coupling supporting pieces 110 and 110 'are provided between the elevating supporting pieces 120 and 120' , And the guide support pieces 130 and 130 'are disposed and formed so as to be spaced apart from each other between the engagement support pieces 110 and 110' .

Accordingly, when the detachable rods 10 and 10 'are engaged with the support pieces, the detachable rods 10 and 10' are inserted into the flow grooves 111 of the engaging and supporting pieces 110 and 110 ' The elevating protrusions 11 and 11 'formed on the detachable rods 10 and 10' may be separated from the coupling holding pieces 110 and 110 'according to the flow. It is possible to flow in the forward and backward direction while being in contact with the side surface of the pipe.

Therefore, the state in which the detachable rods 10 and 10 'are pulled out in the outer direction of the filter case 100 will be the same as that shown in FIG. 4. In this state, a cross section taken along line A-A' B-B 'will be as shown in Fig.

That is, when the air filter of the present invention is pushed into the filter insertion portion 301 formed on the side of the air cleaner 300, the filter insertion portion 301 having a width higher than the upper and lower heights of the filter case 100, The air filter will be easily inserted without any resistance.

At this time, since the elevation protrusions 11 and 11 'of the detachable rods 10 and 10' are not inserted into the elevation support pieces 120 and 120 ', the elevation protrusions 11 and 11' The bottom surface is in contact with the bottom surface of the filter insertion portion 301 and the inside end of the flow groove 111 and the fitting groove 121 and the guide groove 131 is in contact with the top of the detachable rods 10 and 10 ' The filter case 100 will enter the filter insertion portion 301 of the air cleaner 300 in the lowest state.

In this state, if the detachable rods 10 and 10 'on both sides of the filter case 100 are pushed inward as shown in FIG. 6, the lifting rods 11 and 11' of the detachable rods 10 and 10 ' Is inserted into the fitting groove 121 of the lifting and supporting piece 120 or 120 'as shown in the sectional view taken along line B-B' of FIG. 7 by the guide insertion portion 11a having a tapered shape at one end. The inner tip of the fitting groove 121 is positioned at the upper end of the elevating protrusions 11 and 11 'through the guide insertion portion 11a so that the filter case 100 is entirely raised as a result will be.

On the other hand, the guide grooves 131 of the flow guide grooves 111 and the guide support pieces 130 and 130 'of the coupling support pieces 110 and 110' A space is formed between the front ends of the detachable rods 10 and 10 'so that the space corresponds to the rising width of the filter case 100, and more specifically, the space between the detachable rods 10 and 10' 11 " and 11 ".

Therefore, the filter case 100 is lifted up to a predetermined height through insertion of the detachable rods 10 and 10 'in the forward direction, and the packing 103 inserted into the flange portion 101 at the front end of the filter case 100 Is in tight contact with the inner surface of the filter insertion portion 301 of the air cleaner 300 so that the airtight coupling state can be achieved.

Accordingly, in the air filter of the present invention, the process of inserting the air filter into the filter insertion portion 301 of the air cleaner 300 can be performed very easily. In the state where the air filter is inserted, The filter case 100 is lifted to a height corresponding to the elevation protrusions 11 and 11 'of the detachable rods 10 and 10' only by pushing the inner case 10 and 10 'inside the air cleaner 300 Tight coupling state of the air cleaner 300 with respect to the filter insertion portion 301 is achieved due to the compression of the packing 103.

Therefore, the air introduced from the lower side of the air cleaner 300 passes through the filter paper 200 of the filter case 100 and can be supplied to the engine through the upper side of the air cleaner 300 along the intake manifold.

When the air filter of the present invention is to be separated and removed from the air cleaner, the handle groove 13 provided at the hook portion 14 of the detachable rod 10 (10 ') exposed to both sides of the filter case 100 When the finger of the operator is lightly pulled, it is possible to pull the finger from the fitting groove 121 of the lifting support piece 120 (120 ') of the filter case 100 to the lifting projection 11 ( The filter case 100 is entirely lowered while the flow grooves 111 and the guide grooves 131 which have been lifted due to the removal of the filter inserts 301 and 11 ' .

Particularly, since the detents 12 and 12 'formed on the detachable rods 10 and 10' are configured to be spaced apart from one or both sides of the guide retention pieces 130 and 130 ' 10 and the detent jaws 12 and 12 'and the guide support pieces 130 and 130' are interfered with each other in the forward direction insertion or reverse direction separation process of the filter case 100, (10 ') can be prevented from being separated due to excessive force.

Therefore, in the air filter of the present invention, by simply pressing the detachable rods 10 and 10 'together with the air filter in the insertion direction in the process of attaching the air filter to the air cleaner 300, The air filter can be easily separated even when the detachable rod 10 or 10 'is simply pulled out without any operation or process even when the air filter is to be removed. It is.

The elevating protrusions 11 and 11 'formed along the longitudinal direction of the detachable rods 10 and 10' are inserted into the fitting grooves 121 of the lifting and supporting pieces 120 and 120 ' Therefore, even if the vertical vibration of the vehicle is repeatedly and continuously operated, it is possible to maintain the engagement state more stably from the vertical vibration through the coupling structure in the lateral direction, No gap is generated.
