Description

Technical Field

[0001] This invention relates to an air purifier, and more specifically, to an air purifier that incorporates a filter support structure comprising a first body and a second body. The first body supports a filter component and has a protrusion on its lower side. The second body is disposed below the first body and has a recessed portion. One side of the recessed portion has an inclined surface that contacts the protrusion. This allows the filter component, which is being guided into the interior space of the housing and directed outwards, to move upwards while simultaneously sealing the retaining portion. This improves the ease of filter maintenance. Background Technology

[0002] An air purifier is a device that forcibly draws in polluted outside air, purifies it, and then discharges the purified, filtered air to the outside. An air purifier includes an air supply unit and a filter element. The air supply unit allows outside air to enter the purifier, and the filter element filters out impurities such as dust and bacteria from the air. This type of known air purifier is configured to forcibly draw in polluted air in an indoor space such as a home or office, collect and filter it, and then recirculate the purified air back into the room.

[0003] The air purifier disclosed in Korean Patent Publication No. 2015-0126328 by KVRK Co., Ltd. has a filter unit housed in a filter housing in the main body. This filter unit consists of multiple filters, including a pre-filter, a pre-treatment filter, a functional filter, a HEPA filter, and a deodorizing filter. In this design, the filter unit itself cannot be mechanically removed structurally. Therefore, to remove the filter unit from the filter housing, the user must directly hold the filter unit with both hands, which presents a hygiene problem. Furthermore, when only a portion of the filter, such as a HEPA filter, needs to be replaced, it is inconvenient to completely separate the filter unit outside the filter housing.

[0004] Korean Patent Publication No. 2020-0097574, issued by Bodefraud Co., Ltd., discloses an air purifier with an easily replaceable filter. When the user presses a button-connector exposed to the outside, the force transmitted therefrom causes the filter pressing component to laterally press the airtight retaining portion of the filter component, thus exposing a portion of the filter component to the outside of the housing component. However, in this case, since the filter component is pressed laterally, it is somewhat in an unstable state, tilted in the opposite direction to the pressurized portion exposed to the outside of the housing component. Furthermore, there is no component that applies pressure to the filter component perpendicular to the ground when the air purifier is running, thus resulting in a drawback in effectively maintaining the airtightness of the filter component. Summary of the Invention

[0005] Technical Problem to be Solved

[0006] In order to solve the above problems, the air purifier of the present invention aims to introduce a filter support structure, which includes a first main body and a second main body.

[0012] The purpose of the air purifier according to an embodiment of the present invention is that the mounting portion of the first body is configured as a protruding structure corresponding to the shape of the filter element, and the connecting portion of the third body is formed as a shape corresponding to the mounting portion, thereby improving the bonding force between the first body and the third body.

[0013] The purpose of the air purifier according to an embodiment of the present invention is to have a pressure stop on one side of the third body, the pressure stop temporarily pressurizing a portion of the second body, thereby allowing the second body to be extended only when an external force is applied, preventing the filter element from suddenly moving vertically in the locked position.

[0014] The purpose of the air purifier according to an embodiment of the present invention is to have a support portion on one side of the third main body, the support portion protruding towards the ground to support the load of the filter support structure, thereby preventing the filter support structure from separating or being damaged during discharge and improving the stability of the filter support structure.

[0015] The purpose of the air purifier according to an embodiment of the present invention is to include a locking part that temporarily restricts the relative movement of the second body with respect to the first body before the filter support structure is fully inserted into the housing, thereby causing the filter element to rise or fall only at a predetermined position.

[0016] The purpose of the air purifier according to an embodiment of the present invention is to introduce a locking part, the locking part including a locking groove and an elastic stop member, the elastic stop member protruding from a third body and descending toward the locking groove, thereby improving the accuracy of the relevant control of the locking part.

[0017] The purpose of the air purifier according to an embodiment of the present invention is to form an inclined surface on one side of the locking groove included in the locking part, so that the elastic stop can rise or fall smoothly without obstruction.

[0018] The purpose of the air purifier according to an embodiment of the present invention is to have a guide portion on one side of the fourth body, the guide portion being combined with an elastic stop to guide the rise or fall of the elastic stop, thereby improving the operational accuracy and stability of the locking portion.

[0063] The words and terms used in this specification and claims should not be interpreted in their usual or dictionary sense, but rather should be interpreted in accordance with the principle that the inventor may define terms and concepts in order to best explain his invention, so as to conform to the meaning and interpretation of the technical idea of ​​the invention.

[0064] Therefore, the embodiments described in this specification and the structures shown in the accompanying drawings are preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Thus, at the time of application of the present invention, there may be various equivalents and modifications of this structure.

[0065] In this specification, the terms "including" or "having" should be understood to specify the presence of features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, without precluding the possibility of the presence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.

[0066] When a component is located "in front of," "behind," "above," or "below" another component, it means, unless there are special circumstances, that it is not only positioned in front of, behind, above, or below another component in direct contact with it, but also includes situations where other components are positioned in between. Furthermore, when a component is "connected" to another component, it means, unless there are special circumstances, that it includes not only direct connections but also indirect connections.

[0067] Hereinafter, an air purifier according to an embodiment of the present invention will be described with reference to the accompanying drawings. Figure 1 This is a perspective view showing the state in which the filter element is exposed outside the housing in an air purifier according to an embodiment of the present invention. Figure 2 This is a perspective view of an air purifier according to an embodiment of the present invention, viewed from below and looking upwards. Figure 3 This is a side view showing the locked position state of an air purifier according to an embodiment of the present invention; Figure 4 This is a side view showing the disassembled position of an air purifier according to an embodiment of the present invention; Figure 5 This is a side view showing the filter component exposed outside the housing in the disassembled position of an air purifier according to an embodiment of the present invention. For clarity of the invention, parts unrelated to the description are omitted in the drawings.

[0068] An air purifier 100 according to an embodiment of the present invention includes a fan 32 and a filter element 20, and is a device that draws in polluted air, purifies it, and then discharges the purified air. In particular, the air purifier 100 according to an embodiment of the present invention incorporates a unique filter support structure 40, which improves the convenience for users to replace and maintain the filter element 20. Hereinafter, the various structures of the air purifier 100 according to an embodiment of the present invention will be described, with a focus on the structure and effect of the filter support structure 40.

[0069] Reference Figure 1 and Figure 2 An air purifier 100 according to an embodiment of the present invention includes: a housing 10; a filter element 20 disposed inside the housing 10 and filtering external air; a retaining part 30 disposed inside the housing 10 on the upper side of the filter element 20; and a filter support structure 40 for mounting the filter element 20 and for being extendable to the outside of the housing 10.

[0070] First, the outer casing 10 forms the exterior of the air purifier 100 and can be formed in a box shape to provide internal space for configuring the various structures. At this time, as... Figure 1 As shown, the outer casing 10 can be formed in the shape of a right-angled hexahedron, or, although not shown in the figures, in the shape of a cylinder. However, the shape of the outer casing 10 is not limited to these, and various shapes of outer casings that form internal spaces can be used.

[0071] In one embodiment of the present invention, reference is made to... Figure 2The outer casing 10 may have a plurality of intake ports 13, which penetrate at least a portion of the outer casing 10, thereby allowing the intake of external air. As an example, as shown in the figure, the intake ports 13 may be formed into the shape of a slot extending in one direction or a circular opening, etc. In addition, the intake ports 13 may be evenly distributed along the outer surface of the outer casing 10 to uniformly intake external air without being biased towards a particular direction.

[0072] In one embodiment of the invention, the housing 10 may be configured such that at least a portion of one side 12 is open to expose the interior space to the outside. As a non-limiting example, a portion of the outer side of the housing 10 may be completely detachable from the housing 10, or a portion of the outer side of the housing 10 may be hinged to the housing 10 and rotatable about a rotation axis. Thus, making one side 12 of the housing open allows the filter element 20 disposed inside the housing 10 to be routed to the outside of the housing 10 by the movement of the filter support structure 40, which will be described later. A detailed description of this will follow with a description of the filter support structure 40.

[0073] On the other hand, such as Figure 2 and Figure 3 As shown, a retaining portion 30 can be formed on one side of the internal space of the outer casing 10. The retaining portion 30 is formed as a plate extending in a direction parallel to the ground, and can be configured such that the outer edge of the retaining portion 30 is connected to the inner side of the outer casing 10. Through the retaining portion 30, the internal space of the outer casing 10 can be divided into an upper space and a lower space. The upper space is located above the retaining portion 30 and is where the fan 32 is disposed, while the lower space is located below the retaining portion 30 and is where the filter element 20 is disposed. Referring to... Figure 2 In order to connect the upper and lower spaces of the housing 10, the retaining part 30 includes multiple through holes, so that the air filtered by the filter component 20 can move towards the upper space of the housing 10. In this way, the air moving towards the upper space of the housing 10 is finally discharged to the outside through the exhaust port 14 formed on the upper part of the housing 10 by the fan 32.

[0074] In one embodiment of the present invention, such as Figure 3As shown, the lower part of the retaining portion 30 can contact the filter element 20. In this case, the portion of the retaining portion 30 that contacts the filter element 20 can be shaped to correspond to the upper end of the filter element 20, so that the filter element 20 can be fixed to the retaining portion 30. As an example, it can be shaped such that a portion of the retaining portion 30 surrounds the outer edge of the upper end of the filter element 20. Accordingly, when the filter element 20 rises through the filter support structure 40 (described later) and contacts the retaining portion 30, the filter element 20 can be stably fixed by the retaining portion 30, resulting in a portion of the filtered air discharged from the filter element 20 not flowing laterally out of the filter element 20. That is, by blocking the movement between the filter element 20 and the retaining portion 30 by the retaining portion 30, the airtightness between the filter element 20 and the retaining portion 30 can be improved. Hereinafter, the position where the filter element 20 contacts the retaining portion 30 and is fixed therein will be defined as the "locked position".

[0075] In one embodiment of the present invention, the filter element 20 disposed below the locking part 90 can be a known filter element. As a non-limiting example, the filter element 20 can be composed of a dust collection filter or an antibacterial filter. The dust collection filter collects ultrafine dust of 0.1 to 0.3 μm or micro dust of 0.3 μm or larger from the air, such as ULPA (Ultra-Low Permeability Filter Air) filter, HEPA (High Efficiency Particulate Air) filter, medium efficiency filter, pre-filter, etc., while the antibacterial filter filters bacteria or microorganisms from the inhaled air. In addition, the filter element 20 can be formed as a part of the structure of the above-mentioned filter elements that can only partially separate. Then, the accompanying drawings show a filter element 20 with a quadrilateral prism shape, but the shape of the filter element 20 is not limited to this, and includes filter elements with cylindrical shapes, etc., and filter elements of various shapes can be applied.

[0076] On the other hand, such as Figure 3 As shown, the filter element 20 rises towards the locking part 30 via the filter support structure 40 (described later) and then contacts the locking part 30, or it can be in a locked position in a fixed state; or it can be as follows: Figure 4 As shown, the filter element 20 descends towards the ground via the operation of the filter support structure 40, and can also be positioned in a disassembled position at a predetermined distance a from the locking part 30. In particular, in the disassembled position, the airtightness between the locking part 30 and the filter element 20, which is achieved in the locked position, can be released.

[0077] Figure 6 This is a perspective view showing a filter support structure of an air purifier according to an embodiment of the present invention; Figure 7 and Figure 8 It is separation Figure 6 An exploded perspective view of the filter support structure is shown. Figure 9This is a cross-sectional perspective view of the filter support structure showing the locked position. Figure 10 This is a cross-sectional perspective view of the filter support structure showing its disassembled position. Figure 11 This is a cross-sectional perspective view showing a portion of the filter support structure exposed outside the housing. Figure 12 This is a perspective view of the filter support structure in the locked position from the rear side. Figure 13 This is a perspective view of the filter support structure from the rear, showing its disassembled position.

[0078] An air purifier 100 according to an embodiment of the present invention includes a filter support structure 40, which supports the lower part of a filter element 20. In this case, with one side 12 of the outer casing 10 open, the filter support structure 40 can be extended outward along the direction of the side 12. That is, if it is necessary to separate the filter element 20 to the outside of the outer casing 10 for reasons such as replacement or maintenance, the filter support structure 40 can be extended outward by the user's external force. This will be discussed below. Figure 1 Based on this, the direction of exporting the filter support structure 40 to the outside of the housing 10 is defined as "export direction d1", and conversely, the direction of importing to the internal space side of the housing 10 is defined as "import direction d2".

[0079] More specifically, refer to Figures 6 to 8 The filter support structure 40 may include a first body 50 and a second body 60.

[0080] The first body 50 can be formed as a plate shape having an area corresponding to the internal space of the outer casing 10. In this case, a mounting portion 52 can be formed in the central portion of the first body 50, the mounting portion 52 mounting the filter component 20, and a frame portion 51 can be arranged around the outer side of the mounting portion 52. At this time, as... Figure 6 As shown, the mounting portion 52 can be formed to protrude a predetermined height from the frame portion 51 toward the filter member 20. As a specific example, the mounting portion 52 can be a protruding structure with a circular or quadrilateral shape, corresponding to the shape of the filter member 20. Thus, the mounting portion 52 protrudes toward the filter member 20, allowing it to be inserted into the lower part of the filter member 20 in an insertion portion (not shown) formed with a shape corresponding to the mounting portion 52. Accordingly, the filter support structure 40 can stably support the filter member 20 during insertion or removal, preventing the filter member 20 from tilting or falling to one side. On the other hand, a space can be formed inside the mounting portion 52 to accommodate the connecting portion 72 of the third body 70, which will be described later. This will be explained later in connection with the connecting portion 72.

[0081] Then, a protrusion 54 can be disposed below the first main body 50, and the protrusion 54 protrudes and extends in the direction of the ground. At this time, for the extension length of the protrusion 54, when the filter member 20 is in the disassembled position, it can be the same as the interval distance a between the filter member 20 and the locking portion 90. Then, the protrusion 54 can include a plurality of protrusions 54 that are spaced apart from each other along the area corresponding to the frame portion 51 and all have the same height.

[0082] In an embodiment of the present invention, a second main body 60 can be disposed below the first main body 50. At this time, in the second main body 60, a groove portion 62 can be formed at a position corresponding to the protrusion 54 of the first main body 50 described above, and the groove portion 62 has a space to accommodate the protrusion 54. Then, the groove portion 62 can have a first inclined surface 63, and the first inclined surface 63 contacts the protrusion 54 of the first main body 50 and is formed as a straight line or a curve. Accordingly, when the protrusion 54 is supported by the first inclined surface 63 and advances or retreats along the first inclined surface 63 in the lead-out direction d1 or the lead-in direction d2, the first main body 50 can rise in the direction of the blocking portion 30 or descend in the direction of the ground.

[0083] As a specific example, as Figure 7 shown, the second main body 60 can be formed in a "C" shape. In this way, the second main body 60 is formed in a "C" shape so that the coupling portion 72 of the third main body 70 to be described later penetrates the second main body 60, which will be described later through the related description of the third main body 70. On the other hand, when the second main body 60 is formed in a "C" shape, a plurality of the groove portions 62 can be respectively formed at positions corresponding to the plurality of protrusions 54 of the first main body 5 along the mutually facing sides of the "C" shape. In this way, the plurality of protrusions 54 and the groove portions 62 are respectively formed, and thus the load of the first main body 50 can be dispersed with respect to the second main body 60, and the stability of the filter member can be further improved when the first main body 50 is lifted and lowered.

[0084] Hereinafter, the operating relationship between the first main body 50 and the second main body 60 will be described in more detail. Initially, as Figure 9 shown, in the locked position where the filter member 20 is fixed by the blocking portion 30, the first main body 50 can be located at this locked position in a state of being supported by the uppermost side of the first inclined surface 63. If the user pulls the second main body 60 toward the lead-out direction d1 side in this state, the entire first inclined surface 63 moves toward the lead-out direction d1 side. Accordingly, as Figure 10As shown, the protrusion 54 of the first body 50, which contacts the first inclined surface 63, moves along the first inclined surface 63 to a position adjacent to the lowest part of the first inclined surface 63. As a result, the first body 50 descends a predetermined distance a towards the ground to the disassembly position of the removable filter component 20, and the filter component 20, fixed to the mounting portion 52 of the first body 50, also descends. In this case, the first body 50 does not need to move in a horizontal direction (either the outgoing or incoming direction), but can move only in a vertical direction (perpendicular to the ground). Then, if the second body 60 is pulled in the outgoing direction d1, then... Figure 11 As shown, the first body 50 and the second body 60 can move together and be exposed to the outside of the outer casing 10.

[0085] On the contrary, such as Figure 10 As shown, when the first body 50 remains stationary in the disassembled position, if the second body 60 is introduced in the inlet direction d2, which is opposite to the outlet direction d1, relative movement of the second body 60 relative to the first body 50 occurs, and the protrusion 54 rises along the first inclined surface 63 of the groove 62. Accordingly, the first body 50 rises as a whole toward the locking part 30, thereby allowing the filter component 20 to move toward a locked position where it contacts the locking part 30 and is fixed therein.

[0086] Thus, according to an embodiment of the present invention, the air purifier 100 includes a filter support structure 40, which comprises a first main body 50 and a second main body 60. The first main body 50 has a protrusion, and the second main body 60 has a groove 62. One side of the groove 62 forms an inclined surface that contacts the protrusion. This allows the filter component 20, which is being introduced into the interior space of the housing and then moved upwards, to seal against the retaining part 30. This improves the convenience for users to maintain the filter. In other words, the introduction and sealing of the filter component are achieved through a series of continuous actions. Therefore, the user can insert the filter component 20 into the housing 10 and simultaneously move it upwards towards the retaining part 30 for fixation using only a single action.

[0087] In one embodiment of the present invention, such as Figure 9As shown, the recessed portion 62 may have a engaging surface 64, which is vertically oriented except for the first inclined surface 63 that contacts the protrusion 54. In this case, the first inclined surface 63 may be formed on the outgoing direction d1 side of the recessed portion 62, and the engaging surface 64 may be formed on the incoming direction d2 side. Accordingly, if the protrusion 54 contacts the engaging surface 64 in the disassembled position, its relative movement in the incoming direction d2 is restricted by the engaging surface 64. As a result, when the second body 60 is outgoing in the outgoing direction d1, one side of the protrusion 54 receives the force transmitted from the engaging surface 64, and thus the first body 50 can also be outgoing integrally with the second body 60. In other words, before the protrusion 54 contacts the engaging surface 64, the first body 50 is restricted from moving from the locked position in the discharge direction d1, and can only move towards the ground (the filter component 20 moves from the locked position to the released position). However, if the protrusion 54 contacts the engaging surface 64, the first body 50 can move together with the second body 60 in the discharge direction d1 under the force of the engaging surface 64. Accordingly, the user does not need to distinguish between the control for raising and lowering the filter component 20 and the control for discharge to the outside of the housing, and can perform these actions continuously, thus improving the user's operational convenience.

[0088] On the other hand, such as Figure 9 As shown, a second inclined surface 55 with a predetermined angle may be formed on the end side of the protrusion 54 of the first body 50. In this case, the second inclined surface 55 may have an inclination corresponding to the first inclined surface 63 formed in the groove 62 of the second body 60. Accordingly, the first body 50 moves more stably when rising or falling via the second body 60, thereby improving the stability of the filter member 20 disposed on the first body 50. However, the protrusion 54 with the second inclined surface 55 is only one example; depending on the requirements, a protrusion 54 without the first inclined surface 63 may also be applied.

[0089] According to an embodiment of the present invention, the filter support structure 40 of the air purifier 100 may include a third body 70, which is disposed at the lower part of the second body to support the second body 60.

[0090] Specifically, referring to Figure 7, the third body 70 may include a coupling part 72 that couples with the mounting part 52 of the first body 50 described above. That is, when the filter member 20 is in the locked position, if the first body 50 is in a state of rising toward the blocking part 30 and then the first body 50 descends through the export of the second body 60, the mounting part 52 of the first body 50 may be coupled to the coupling part 72 of the third body 70. Thus, the first body 50 is coupled to the third body 70, and further, when the first body 50 descends, it does not move toward the export direction d1 or the import direction d2 side, but can rise or descend only or mainly in a direction perpendicular to the ground. Then, after the first body 50 completely descends, as described above, the protruding part 54 contacts the engaging surface 64, and accordingly, it receives the force transmitted from the blocking part 30 and moves in the export direction d1. The third body 70 coupled to the first body 50 is the same as the first body 50 and can be exported integrally with the second body 60. Thus, through the third body 70, when the first body 50 rises / descends or moves in the export / import direction, the first body 50 can be more effectively supported, and thus the stability of the filter member 20 located on the upper side can also be further improved.

[0091] In an embodiment of the present invention, the coupling part of the third body 70 may be formed in a shape corresponding to the mounting part of the first body 50. As an exemplary example, when the mounting part 52 of the first body 50 is formed in a quadrilateral shape, the coupling part 72 is formed in a quadrilateral shape slightly smaller than the mounting part 52 and can be coupled in a form inserted into the space formed inside the mounting part 52. Accordingly, while the mounting part 52 of the first body 50 performs the function of mounting the filter member 20, the shape itself can be coupled to the coupling part 72 of the third body 70. Therefore, without a separate coupling tool, a stable coupling force can also be obtained.

[0092] In this case, as described above, the second body 60 may be formed in a "C" shape. At this time, as Figure 9 shown, inside the second body 60 formed in a "C" shape, the coupling part 72 of the third body 70 is configured to penetrate the second body 60, and the uppermost part of the coupling part 72 may be located more above the second body 60. Accordingly, if the first body 50 descends toward the ground direction (moves to the disassembly position) through the export of the second body 60 after being in the locked position, the coupling part of the third body 70 is inserted into the mounting part of the first body 50, and further, the mounting part 52 and the coupling part 72 can be coupled to each other. Thus, the air purifier 100 according to an embodiment of the present invention can easily couple between the first body 50 and the third body 70 through the "C" shaped second body 60 and the coupling part 72 penetrating the second body 60.

[0093] On the other hand, referring to Figure 12A pressure stop 74 may be provided on one side of the third body 70, which temporarily presses a portion of the second body 60. The pressure stop 74 is formed of a resilient material and can laterally press against a position corresponding to a groove formed on one side of the second body 60. The pressure stop 74 presses the second body 60 to restrict its free movement, allowing it to be extended only when a target external force is applied by the user in the locked position. For example, if the air purifier 100 is tilted towards one side 12 of the housing in the locked position for unavoidable reasons, without a component such as the pressure stop 74 described above, the second body 60 would be extended in the extension direction d1 due to gravity, thereby allowing the first body 50 to descend to the disassembled position. The pressure stop 74 prevents the filter element 20 from moving so suddenly in the vertical direction.

[0094] Re-reference Figures 6 to 8 A support portion 76 may be provided on one side of the third main body 70, protruding towards the ground. In this case, the support portion 76 may be formed adjacent to the portion held by the user for extending the second main body 60. When extending the filter support structure 40 out of the housing 10, the support portion 76 is in direct contact with the ground, supporting the load of the filter support structure. Thus, with the support portion 76, even when extending the filter support structure 40 out of the housing 10, it will not be floating in the air, but the load can be distributed through the ground. As a result, through the load of the filter element 20, the filter support structure 40 can be completely separated from the air purifier 100, or an accident involving damage to a portion of the filter support structure 40 can be prevented.

[0095] In one embodiment of the invention, the filter support structure 40 may include a locking part 90, which temporarily restricts the relative movement of the second body 60 relative to the first body 50 before the filter support structure 40 is fully inserted into the housing 10.

[0096] As described above, when the second body 60 moves relative to the first body 50, the first body 50 can descend from the locked position to the disassembled position or rise from the disassembled position to the locked position via the second body 60. That is, when the first body 50 is not moving in a horizontal direction (outward or inward direction), and only the second body 60 moves in the outward or inward direction (relative to the first body), the first body 50 can rise or fall in a direction perpendicular to the ground. However, if the relative movement of the second body 60 occurs while the third body 70 of the first body 50 is located outside the housing 10, the filter element 20 rises to the locked position while located outside the housing 10. To prevent the filter element 20 from rising or falling in such an unpredictable position, the locking part 90 can temporarily restrict the relative movement of the second body 60 while the third body 70 is located outside the housing 10.

[0097] As a specific example, refer to Figure 10 The locking part may include a locking opening 92, a locking groove 94, and a resilient stop 96. First, the locking opening 92 may be an opening formed on the underside of the third body 70 and having an area corresponding to the resilient stop 96. Then, the locking groove 94 is a recessed structure formed in the base portion 16 within the housing 10, such as... Figure 10 As shown, when the third body 70 is fully inserted into the housing 10, it can be formed in a position facing the aforementioned locking opening 92, and can have an internal space corresponding to the volume of the elastic stop 96. Then, the elastic stop 96 has a built-in compression spring, which can protrude towards the lower part of the third body 70 through the locking opening 92. If it is located above the locking groove 94 formed in the base portion 16 of the housing, as... Figure 12 As shown, it descends toward the locking groove 94, thereby fixing the third body 70 and preventing it from moving in the export direction d1 or the import direction d2. Figure 11 As shown, when the elastic stop 96 is located in a position other than the locking groove 94 (when the third body 70 is being extended towards the extending direction d1), the spring is compressed by the base portion 16 of the housing 10, thereby maintaining the state of being disengaged from the locking groove 94 and rising towards the blocking portion 30. As a result, the third body 70 is not fixed to the housing 10, and therefore the third body 70 can move towards the extending direction d1 or the introducing direction d2. Thus, when the elastic stop 96 rises towards the blocking portion 30, one end 66 of the second body 60 is restricted by the rising elastic stop 96 to move in the introducing direction d2, thereby restricting the relative movement with respect to the first body 50 (see reference). Figure 13Then, the third body 70 is fully inserted into the interior of the housing 10, and the second body 60 can move in the insertion direction d2 only when it is lowered toward the locking groove 94 with the elastic stop 96 located above the locking groove 94. Accordingly, the second body 60 can move relative to the first body 50 only at a predetermined position (when the third body 70 is fully inserted into the housing 10).

[0098] At this time, as Figure 10 and Figure 11 As shown, a third inclined surface 95 can be formed on a portion of the locking groove 94 on the outgoing direction d1 side. Accordingly, when the third body 70 moves, the elastic stop 96 can smoothly rise in the direction of the blocking part 30 without being stuck by the locking groove 94.

[0099] In one embodiment of the invention, the filter support structure 40 may further include a fourth body 80. (Refer to previous text) Figures 7 to 9 The fourth body 80 can be combined with the third body 70 to move integrally with it. Furthermore, a second body 60 can be disposed between the third body 70 and the fourth body 80, and a portion of the handle side of the second body 60 can be covered by the fourth body 80. As a result, when the second body 60, partially covered by the fourth body 80, moves in the outward direction d1 or the inward direction d2, the load on the fourth body 80 can prevent the second body 60 from lifting towards the stop portion 30. Then, frame portions 84 are provided on both sides of the fourth body 80, the frame portions 84 having a predetermined height and surrounding the outer frame of the first body 50, thereby stably guiding the first body 50 to rise or fall. Additionally, as... Figure 13 As shown, a guide portion 82 may be provided inside the fourth body 80. This guide portion 82, in conjunction with the elastic stop 96, can stably guide the upward or downward movement of the elastic stop 96. At this time, a connecting protrusion or connecting groove extending in the upward or downward direction of the elastic stop can be formed on the outer peripheral surface of the guide portion 82, and a corresponding connecting groove or connecting protrusion can be formed on the elastic stop 96. Then, track components may be provided on both sides of the fourth body 80. These track components interact with other track components disposed on the inner side of the housing, thereby allowing for smooth, frictionless guidance when the filter support structure 40 slides in the outward direction d1 or the inward direction d2.

[0100] The above description illustrates one embodiment of the present invention. However, the concept of the present invention is not limited to the embodiment presented in this specification. Rather, those skilled in the art who understand the concept of the present invention can easily propose other embodiments by adding, changing, deleting, or adding components within the same conceptual scope, and these are also included within the conceptual scope of the present invention.
