Description

vacuum cleaner

The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner capable of compressing dust collected inside a dust container.

In general, a vacuum cleaner is a household appliance that sucks in small garbage or dust by sucking air using electricity and fills the dust bin in the product, and is generally called a vacuum cleaner.

Such a vacuum cleaner may be divided into a manual cleaner in which the user directly moves the cleaner to perform cleaning, and an automatic cleaner in which the user performs cleaning while driving by themselves. Manual vacuum cleaners may be classified into canister-type cleaners, upright cleaners, handy-type cleaners, stick-type cleaners, and the like, depending on the type of cleaner.

In the past, canister-type vacuum cleaners were often used in household cleaners, but recently, a hand-held cleaner and a stick cleaner, which are convenient to use by providing a dust container and a cleaner body, are increasingly being used.

The canisty type vacuum cleaner is connected to the main body and the suction port by a rubber hose or pipe, and in some cases, it can be used by inserting a brush into the suction port.

The Hand Vacuum Cleaner maximizes portability, and since it is light in weight but short in length, there may be restrictions on the cleaning area while sitting. Therefore, it is used to clean localized places such as on a desk or sofa, or in a car.

The stick vacuum cleaner can be used while standing, so you can clean without bending your back. Therefore, it is advantageous for cleaning while moving a large area. If a hand-held vacuum cleaner cleans a narrow space, the stick-type vacuum cleaner can clean a wider space than that, and can clean a high place that cannot be reached by hand. Recently, a stick cleaner is provided in a module type, and the cleaner type is actively changed and used for various objects.

Meanwhile, Korean Patent Laid-Open Patent KR10-2020-0031509A discloses a cleaner capable of compressing dust in a dust bin and discharging the dust in the dust bin from the dust bin.

In the vacuum cleaner, a compression lever for compressing the dust container is disposed on the left side of the handle when the user holds the handle and puts the suction unit in front of the user.

Accordingly, in the case of a right-handed person, the dust in the dust container can be compressed by holding the handle with the right hand and pulling the compression lever with the left hand. However, since it is difficult to pull the compression lever with the right hand in the case of a left-handed person who generally holds the handle with the left hand, there is an inconvenience of having to pull the compression lever after changing the hand holding the handle.

In addition, since a suction motor is provided on the upper part of the dust container, there is a spatial limitation in increasing the capacity of the dust container, and accordingly, there is a limitation in that the stroke length of the compression lever is short.

The present invention was created to improve the problems of the prior art as described above, and it is an object of the present invention to provide a cleaner that can easily pull the compression lever not only for right-handed people but also for left-handed people.

Another object of the present invention is to provide a cleaner capable of further increasing a length for compressing dust.

In order to achieve the object as described above, a cleaner according to the present invention includes: a suction unit having a suction passage through which air can flow; a suction motor generating a suction force for sucking air along the suction unit; a dust separation unit including a cyclone for separating dust from the air introduced through the suction unit; and a dust container for storing the dust separated through the dust separation unit.

The dust container may include a dust container body accommodating the dust separation unit therein; a compression lever disposed on the outside of the dust container body and provided to be movable by a stroke; a compressor moving in association with the compression lever and moving along a space between an inner peripheral surface of the dust container body and the dust separation unit; and a transmission unit that passes through the dust container body to connect the compressor and the compression lever, and is positioned radially outside the inner peripheral surface of the dust container body where the cyclone flow is formed.

At this time, the transmission unit, the lever coupling portion to which the compression lever is coupled; and a transfer unit housing accommodating the lever coupling unit to be movable in a straight line, positioned radially outside the inner circumferential surface of the dust container body, and having a pair of through-holes formed therein.

The lever coupling part may be coupled to the two compression levers.

The compression lever may be symmetrically disposed with respect to the transmission unit housing.

The transfer unit may further include a compression rod connecting the lever coupling unit and the compressor.

The compression rod may include: a first compression rod having one end coupled to the lever coupling part; a second compression rod having one end coupled to the compressor; and a rod coupling part to which the other end of the first compression rod and the other end of the second compression rod are coupled.

The transfer unit may further include a spring for elastically supporting the lever coupling unit.

The transfer unit may further include a support bar coupled to the transfer unit housing through the lever coupling unit and guiding the linear movement of the lever coupling unit.

The through hole may be formed in the form of a long hole along the length direction of the dust container body, and the length of the through hole may be 90 mm or more.

The delivery unit housing may include a guide groove formed to correspond to the shape of the lever coupling part to guide the linear movement of the lever coupling part.

At least a portion of the compression rod may be exposed to the outside of the dust container in association with the linear movement of the compression lever.

As described above, according to the vacuum cleaner according to the present invention, a pair of compression levers are symmetrically provided, so that not only right-handed people but also left-handed people can easily pull the compression levers.

In addition, by disposing the suction motor in the rear, the length of the dust bin is increased, and the stroke length of the compression lever is increased to increase the amount of dust compressed.

(1) is a plan view, and FIG. 4 is a cross-sectional view of the cleaner 1 according to an embodiment of the present invention.

1 to 4 , the cleaner 1 according to an embodiment of the present invention may include a body 10 . The body 10 may include a suction unit 100 through which air containing dust is sucked.

In one embodiment of the present invention, the direction may be defined based on when the bottom surface (lower surface) of the dust container 400 and the battery housing 600, which will be described later, are placed on the ground.

In this case, the front may indicate a direction in which the suction unit 100 is disposed with respect to the dust container 400 , and the rear may indicate a direction in which the suction motor 200 or the handle 500 is disposed. In addition, a direction disposed on the right side when the suction unit 100 is viewed from the suction motor 200 may be called a right side, and a direction disposed on the left side may be called a left side. In addition, in an embodiment of the present invention, upper and lower sides may be defined along a direction perpendicular to the ground based on when the bottom surface (lower surface) of the dust container 400 and the battery housing 600 is placed on the ground. .

The body 10 may have an external shape formed by a plurality of housings.

For example, the body 10 may include a first housing 11 having a substantially cylindrical shape, and a second housing 12 coupled to an upper side of the first housing 11 and having a substantially cylindrical shape. In addition, the main body 10 may include a rear housing 14 disposed behind the first housing 11 or the second housing 12 . At this time, the second housing 12 may be connected to the rear housing 14 through the third housing 13 , and the longitudinal directions of the first housing 11 and the second housing 12 are the upper and lower sides of the main body 10 . direction and the longitudinal direction of the rear housing 14 may be disposed to be perpendicular to both the front-rear direction and the vertical direction. In other words, when the direction in which the longitudinal axis A1 of the suction unit 100 is disposed is the x-axis direction, the rear housing 14 may be disposed in the y-axis direction in the longitudinal direction, and the first housing ( 11) and the second housing 12 may be disposed in the z-axis direction in the longitudinal direction.

On the other hand, in expressing that the first housing 11 and the second housing 12 are disposed in front of the main body 10 and the rear housing 14 is disposed in the rear of the main body 10, a handle 500 to be described later The longitudinal axis A4 of the gripper 510 may be a reference (refer to FIG. 2).

The upper end of the first housing 11 and the lower end of the second housing 12 may each have an open shape. That is, the first housing 11 may have an open upper side and the second housing 12 may have an open lower side. The coupling of the second housing 12 to the upper side of the first housing 11 may mean that the upper open part of the first housing 11 and the lower open part of the second housing 12 are coupled.

The body 10 may include a suction unit 100 , a suction motor 200 , a dust separation unit 300 , a dust container 400 , a handle 500 , and a power supply unit 600 .

The suction unit 100 may have a hollow cylindrical shape, may suction air containing dust, and may provide a suction flow path through which air containing dust may flow. Air including dust may be guided to the first housing 11 through the suction unit 100 .

Here, the suction motor 200 may generate an air flow (ie, airflow) by generating a suction force so that air including dust may be introduced into the suction unit 100 . The suction motor 200 may be accommodated in the rear housing 14 (refer to FIG. 4).

The rear housing 14 has a cylindrical shape having a predetermined diameter, and in this case, the suction motor 200 may be seated and accommodated in parallel in the longitudinal direction of the rear housing 14 .

The suction motor 200 may include a motor shaft 210 and an impeller connected to the motor shaft 210 to rotate.

The suction motor 200 may be a brushless DC (BLDC) motor. A BLDC motor is a brushless type DC motor. The BLDC motor has no brushes, which are abrasive parts, so there is less electrical and mechanical noise, and there are no problems with high-speed rotation and low rotational noise.

The dust separation unit 300 communicates with the suction unit 100 and applies the principle of a dust collector using centrifugal force to separate dust sucked into the body 10 through the suction unit 100 .

For example, the dust separation unit 300 may include at least one cyclone capable of separating dust by cyclone flow. The cyclone may communicate with the suction unit 100 . Air and dust sucked through the suction unit 100 are spirally flowed along the inner circumferential surface of the cyclone. The axis A3 of the cyclone flow of the cyclone may extend in the vertical direction.

The dust separation unit 300 may further include a secondary cyclone that again separates dust from the air discharged from the cyclone. In this case, the secondary cyclone may be located inside the cyclone so that the size of the dust separation unit is minimized. The secondary cyclone may include a plurality of cyclone bodies arranged in parallel. Air discharged from the cyclone may be divided into a plurality of cyclone bodies and passed through.

At this time, the axis (A3) of the cyclone flow of the secondary cyclone may also extend in the vertical direction, and the axis (A3) of the cyclone flow of the cyclone and the axis (A3) of the cyclone flow of the secondary cyclone are A coaxial axis may be formed in the vertical direction, and this may be collectively referred to as the axis A3 of the cyclone flow of the dust separation unit 300 .

The dust separation unit 300 may further include a cyclone filter disposed to surround the secondary cyclone unit 330 . The cyclone filter, for example, is formed in a cylindrical shape and guides the air separated from the dust in the cyclone to the secondary cyclone. A cyclone filter can filter out dust as the air passes through it.

To this end, the cyclone filter may include a mesh portion having a plurality of holes. The mesh portion is not limited, but may be formed of a metal material.

Meanwhile, as another example, it is also possible for the dust separation unit 300 to have a single cyclone, and even in this case, the axis A3 of the cyclone flow may extend in the vertical direction.

The handle 500 is a component that allows the user to grip and move the cleaner 1, is disposed in the opposite direction to the suction unit 100 with respect to the dust separation unit 300, and is a part that the user grips with his/her hand. A gripper 510 may be included. Here, the gripper 510 has a substantially cylindrical shape and has an axis A4 in the longitudinal direction. Also, the gripper 510 may be disposed with an upper portion inclined toward the front. The handle 500 and the third housing 13 may be integrally formed.

The power supply unit 600 is a component for supplying power to the suction motor 200 , and includes a battery housing 610 and a battery 620 accommodated in the battery housing 610 . The power supply unit 600 may be disposed to be adjacent to the handle 500 in the upper side, and may be disposed to be adjacent to a lower portion of the outer circumferential surface of the dust container 400 , which will be described later, in the front side. For example, the battery housing 610 may be disposed to be adjacent to the handle 500 in an upper direction, and a lower portion of an outer circumferential surface of the dust container 400 to be described later may be disposed to be adjacent to the front side. In addition, the battery 620 may be provided detachably from the battery housing 610 , but is not limited thereto, and may be provided integrally with the battery housing 610 .

The dust container 400 may store the dust separated by the dust separation unit 300 .

The dust container 400 may include a cylindrical dust container body 410 . For example, it is possible that the cyclone does not exist separately, and the upper portion of the dust container body 410 functions as a cyclone. All or at least a portion of the secondary cyclone may be located in the dust container 400 .

A dust storage guide 414 for guiding the storage of dust separated from the secondary cyclone may be disposed in the dust container body 410 . The dust storage guide 414 may be coupled to the lower side of the secondary cyclone.

The dust storage guide 414 includes a space inside the dust container body 410, a first dust storage unit 412 in which dust separated from the cyclone is stored, and a second dust storage unit 412 in which the dust separated from the second cyclone 330 is stored. It is divided into 2 dust storage units 416 . In other words, the inner space of the dust storage guide 414 is the second dust storage unit 416 , and the space between the dust storage guide 414 and the dust container body 410 is the first dust storage unit 412 .

The body 10 may further include a filter unit 700 disposed on the dust separation unit 300 . The filter unit 700 may include a pre-filter and a HEPA filter.

The pre-filter is configured to filter out dust not collected by the dust separation unit 300 . Here, the pre-filter may be a mesh filter. For example, the pre-filter may include a material of nylon and a spun-bonded fabric. The spunbond nonwoven fabric is a type of nonwoven fabric made by spinning synthetic fibers such as polypropylene (PP, polypropylene) and then applying heat to adhere them.

A high-efficiency particulate air filter (HEPA filter) serves to finally filter out fine dust that has not been filtered out by the pre-filter.

Meanwhile, in the present embodiment, the filter unit 700 is disposed above the dust separation unit 300 , but is not limited thereto, and may be disposed on a flow path through which air flows inside the body 10 .

Hereinafter, a preferred embodiment of the vacuum cleaner 1 according to the present invention will be described focusing on the arrangement relationship of each configuration.

Referring back to FIGS. 1 to 4 , the first housing 11 may include a dust separation unit 300 and a dust container 400 . More specifically, the upper portion of the first housing 11 may be defined as a cyclone, the secondary cyclone may be accommodated in the first housing 11 , and the lower portion of the first housing 11 may be defined as the above-mentioned It may be defined as one dust container 400 .

The suction unit 100 may be disposed where the first housing 11 and the second housing 12 are coupled. More specifically, a portion of the suction passage of the suction unit 100 may be disposed in communication with the first housing 11 and the other portion may be disposed in communication with the second housing 12 .

In addition, the handle 500 and the power supply unit 600 are disposed at the rear of the first housing 11 , and the third housing 13 is disposed at a portion connecting the second housing 12 and the rear housing 14 . do.

On the other hand, in the cleaner 1 according to the preferred embodiment of the present invention, the longitudinal axis A2 of the suction motor 200 is disposed to be perpendicular to the longitudinal axis A1 of the suction unit 100, and the power supply unit ( 600) is arranged parallel to the bottom surface of the. At this time, the longitudinal axis A1 of the suction unit 100 is also disposed parallel to the bottom surface of the power supply unit 600 .

Unlike the preferred embodiment of the present invention, it is assumed that the longitudinal axis A2 of the suction motor 200 is arranged to be parallel to the longitudinal axis A1 of the suction unit 100 . That is, this is a case in which the suction motor 200 extends along the longitudinal axis A1 of the suction unit 100 . In this arrangement, since the long axis of the suction motor 200 is disposed along the front-rear direction, the main body of the cleaner protrudes long in the direction in which the wrist extends when the handle 500 is gripped. Therefore, there is a problem that the grip feeling is not good.

In contrast, in the cleaner 1 according to the preferred embodiment of the present invention, since the long axis A2 of the suction motor 200 is disposed perpendicular to the front-rear direction of the cleaner 10, one It is possible to prevent the configuration from excessively protruding to the rear of the gripper 510 . Accordingly, when the user holds the handle 500 for cleaning, it is possible to reduce a portion that contacts and interferes with the wrist.

In addition, in the cleaner 1 according to the preferred embodiment of the present invention, the outer peripheral surface of the rear housing 14 has a circular shape when the cleaner 1 is viewed from the side. Due to this, when the user holds the handle 500 for cleaning, a curved surface may be naturally formed in a direction in which the wrist extends from the back of the hand. Accordingly, there is an advantage in that the user's grip on the cleaner 1 is further improved.

The handle extension lines L1 and L2 formed by extending a tangent line contacting the outer circumferential surface of the gripper 510 may be disposed to be spaced apart from the suction motor 200 by a predetermined distance in a radial direction.

More specifically, the handle extension lines L1 and L2 are the outermost of the gripping part 510 when the main body 10 is cut and viewed in a plane including the longitudinal axis A1 of the suction part 100 . It may mean virtual extension lines L1 and L2 formed by extending a tangent line contacting the gripper 510 from the protruding outermost points P1 and P2 (see FIG. 4 ).

Since the handle extension lines L1 and L2 are disposed to be spaced apart from the suction motor 200 by a predetermined distance in the radial direction, the handle extension lines L1 and L2 do not pass through the suction motor 200 . In other words, the handle extension lines L1 and L2 and the suction motor 200 do not come into contact at any one point. In other words, the handle extension lines L1 and L2 are disposed so as not to meet any part of the suction motor 200 .

Through this, the center of gravity (G1) of the suction motor 200 may be disposed to be positioned at the rear of the handle extension lines (L1, L2). Also, the center of gravity G1 of the suction motor 200 may be disposed in the opposite direction to the suction unit 100 with respect to the longitudinal axis A4 of the gripper 510 .

Through this arrangement relationship, the center of gravity G1 of the suction motor 200 may be formed close to the user's wrist. Therefore, it is possible to reduce the moment force due to the center of gravity (G1), the load applied to the user's wrist is reduced, has the effect of feeling less fatigue in performing a cleaning operation for a long time.

On the other hand, as described above, the grip portion 510 of the handle 500 is disposed with an upper portion inclined toward the front. Accordingly, the center of gravity G2 of the power supply unit 600 may be disposed to be located in front of the longitudinal axis A4 of the holding unit 510 . That is, the center of gravity G1 of the suction motor 200 and the center of gravity G2 of the power supply unit 600 may be disposed to be positioned in opposite directions with respect to the longitudinal axis A4 of the gripper 510 . .(See Fig. 4)

Through this arrangement relationship, the center of gravity (G2) of the power supply unit 600, which has a heavy weight, based on the grip portion 510, which is the part that the user grasps, and the suction motor 200, which is another heavy weight component, is used. Since the centers of gravity (G1) are in opposite directions to each other, there is an effect of optimizing the weight balance of the main body (10).

In addition, the handle 500 may form a connecting portion on one side of the gripper 510 adjacent to the suction motor 200 . The connecting portion may be formed in a shape that naturally extends without a step difference by forming a portion where the outer peripheral surface of the rear housing 14 and the grip portion 510 are coupled to a curved surface having a predetermined radius.

Through this, when the user grips the gripping part 510, the connection part is seated between the user's thumb and index finger, so that the heavy suction motor 200 is supported on the back of the hand, so the cleaner ( 1) has the effect that it can be supported in a more stable form.

Meanwhile, the bottom surface of the power supply unit 600 and the bottom surface of the dust container 400 (which may be referred to as the bottom surface of the first housing 11 ) do not exist on one plane and may have a step difference. That is, the bottom surface of the power supply unit 600 and the bottom surface of the dust container 400 may be configured to have different heights.

Preferably, the suction motor 200 and the battery 620, which are relatively heavy components, are disposed above the power supply unit 600, and it is preferable that the bottom surface of the power supply unit 600 protrude further downward.

Through this, when the bottom surface of the power supply unit 600 is placed on the floor surface, the main body 10 of the cleaner 1 may be stably supported without falling in the direction of the dust container 400 .

In addition, the longitudinal axis A1 of the suction part 100 may be formed above the grip part 510 of the handle 500 and may be disposed to penetrate at least a portion of the suction motor 200 . More specifically, the longitudinal axis A1 of the suction part 100 disposed at the connection part of the first housing 11 and the second housing 12 has a predetermined distance from the grip part 510 of the handle 500 . It is disposed at the upper part spaced apart, that is, the longitudinal axis A1 of the suction part 100 may be disposed in a form in which the grip part 510 of the handle 500 does not penetrate. ( FIGS. 2 and 4 ) Reference)

Conventionally, when the suction motor 200 is disposed above the dust separation unit 300 , there is a limit to increasing the height of the first housing 11 in consideration of the length of the suction motor 200 . Accordingly, the longitudinal axis A1 of the suction unit 100 to be disposed near the upper end of the first housing 11 had to be disposed to pass through the gripping unit 510 of the handle 500 .

On the contrary, according to a preferred embodiment of the present invention, since the suction motor 200 is disposed on the upper part of the handle 500, the height of the second housing 12 disposed on the upper part of the dust separation unit 300 is reduced and compared with the conventional one. It becomes possible to increase the height of the upper end of the first housing 11 .

Accordingly, when the overall height of the main body 10 is the same, the height of the first housing 11 can be higher than that of the conventional one, so that the height of the dust container 400 can also be formed high, and the dust container 400 can collect dust. The acceptable dose may be increased. This has the advantage of reducing the inconvenience of frequently emptying the dust of the dust container 400 from the user's point of view.

On the other hand, FIG. 5 is an exploded perspective view in which the compression lever, the compressor, and the transmission part are disassembled in the vacuum cleaner according to the embodiment of the present invention, FIG. 6 is a combined perspective view of FIG. 5 , and FIG. 7 is the compression lever in FIG. A perspective view expressing a pulled state is disclosed, and FIG. 8 is a perspective view viewed from another angle in a state in which the compression lever is pulled in the cleaner according to an embodiment of the present invention.

The configuration of the dust container 400 in the cleaner according to the embodiment of the present invention will be described with reference to FIGS. 5 to 8 .

The dust container 400 may include a dust container body 410 , a compression lever 420 , a compressor 430 , a transfer unit 440 , and a discharge cover 450 .

The dust container body 410 may be formed in a hollow cylindrical shape. For example, the lower side of the dust container body 410 is formed in an open shape, and may be opened and closed by the discharge cover 450 . Also, the upper side of the dust container body 410 may be connected to the second housing 12 . In addition, the suction unit 100 may be disposed at the front of the dustbin body 410 , and the suction motor 200 , the handle 500 , and the power supply unit 600 may be disposed at the rear of the dustbin body 410 .

On the other hand, the transmission unit 440 may be coupled to the outer circumferential surface of the dustbin body 410 , and a connection hole through which the compression rod 443 of the transmission unit 440 may pass may be formed in the dustbin body 410 . .

The dust container body 410 may accommodate the dust separation unit 300 therein, and a cyclone flow may occur inside the dust container body 410 . Also, the dust container body 410 may provide a space for storing the dust separated by the dust separation unit 300 .

The discharge cover 450 may be disposed on a lower surface of the dust container body 410 . The discharge cover 450 may selectively open and close the lower portion of the dust container body 410 that is opened downward.

The discharge cover 450 may include a cover body 451 and a hinge portion 452 . The cover body 451 may be formed to block a portion of the lower surface of the dust container body 410 . The cover body 451 may rotate downward based on the hinge part 452 . The hinge part 452 may be disposed adjacent to the battery housing 610 . The discharge cover 450 may be coupled to the dust container body 410 through a hook coupling.

The coupling lever 453 may be configured to separate the discharge cover 450 from the dust container body 410 . The coupling lever 453 may be disposed in front of the dust container body 410 . Specifically, the coupling lever 453 may be disposed on the front side outer surface of the dust container body 410 . The coupling lever 453 may release the hook coupling between the cover body 451 and the dust container body 410 when an external force is applied.

Meanwhile, in the present embodiment, the coupling lever 453 is provided to be pressed in the left and right directions, but is not limited thereto, and may be provided to be pressed in the vertical direction.

When the discharge cover 450 is coupled to the dust container body 410 , the lower surface of the dust container body 410 may be blocked (sealed) by the discharge cover 450 .

The compression lever 420 may be disposed outside the dust container body 410 or the dust separation unit 300 . The compression lever 420 may be provided on the outside of the dust container body 410 or the dust separation unit 300 to be movable in a vertical direction (lengthwise direction).

The compression lever 420 may be connected to the compressor 430 through the transmission unit 440 .

As an example, the compression lever 420 is a button portion 421 formed in a cylindrical shape, a connection portion 422 extending radially outward from the outer circumferential surface of the button portion 421, and a coupling portion protruding from the end of the connection portion, which will be described later.

Specifically, the compressor 430 may move along the space between the inner circumferential surface of the dust container body 410 and the dust separation unit 300 , and may move up and down within the dust container body 410 .

Through this, the compressor 430 may compress the dust in the dust container body 410 downward. Also, when the discharge cover 450 is separated from the dustbin body 410 and the lower part of the dustbin body 410 is opened, the compressor 430 moves from the upper part of the dustbin body 410 to the lower part of the dustbin body 410 . ) can remove foreign substances such as residual dust inside.

The transfer unit 440 may be provided to pass through the dust container body 410 to connect the compressor 430 and the compression lever 420 .

The transfer unit 440 may be located radially outside the inner peripheral surface of the dust container body 410 . Specifically, the transfer unit housing 442 of the transfer unit 440 may be coupled to the outer peripheral surface of the dust container body 410 . In addition, the compression rod 443 of the delivery unit 440 penetrates the outer circumferential surface of the dustbin body 410 and is inserted into the inner space of the dustbin body 410 , but is disposed radially outside the inner circumferential surface of the dustbin body 410 . .

The transmission unit 440 may include a lever coupling unit 441 , a transmission unit housing 442 , a compression rod 443 , a spring 444 , and a support rod 445 .

The lever coupling portion 441 may be coupled to the compression lever 420 . Specifically, the lever coupling portion 441 may be configured such that a pair of compression levers 420 can be symmetrically coupled.

For example, the lever coupling unit 441 may include a pair of coupling posts 4412 having a cylindrical shape and a connecting post 4411 connecting the pair of coupling posts 4412 . At this time, at least a portion of the connecting column 441 is formed to protrude in a curved shape, and may move linearly along the guide groove 4423 of the delivery unit housing 442 . In addition, a coupling groove 4413 coupled to the protrusion 423 of the compression lever 420 may be formed in the coupling column 4412 .

On the other hand, a rod coupling hole 4414 may be formed in any one of the pair of coupling pillars 4412 so that the compression rod 443 is inserted and coupled, and in the other one, a rod through hole 4415 so that the support rod 445 passes therethrough. ) can be formed. For example, a rod coupling hole 114 may be formed in the coupling pillar 4412 formed on the left side of the connection pillar 4411 , and a rod through hole 4415 may be formed in the coupling pillar 4412 formed on the right side. . In addition, the lower surface of the coupling column 4412 on which the rod through hole 4415 is formed may be elastically supported by the spring 444 .

The housing body 4421 may be coupled to the outer circumferential surface of the dust container body 410 to provide a space in which the lever coupling part 441 is linearly movably accommodated. The housing body 4421 is open in the direction (front) of the dust container body 410 , and the rear side of the housing body 4421 has a surface in contact with the handle 500 and/or the battery housing 610 .

The guide holes 4422 are formed in a pair in the housing body 4421 , and may be formed in a long hole shape along the longitudinal direction of the dust container body 410 to guide the linear movement of the compression lever 420 . In this case, the guide hole 4422 may be formed to a predetermined length to limit the compression length of the compression lever 420 . For example, the length of the guide hole 4422 may be 90 mm or more.

With this configuration, the amount of compression inside the dust bin can be increased compared to the conventional case in which a suction motor is provided on the upper part of the dust bin, and the compressed length of the dust bin is 75 mm or less due to space constraints.

The guide groove 4423 is formed in the shape of a groove having a curved surface in the housing body 4421 , and may be formed to correspond to the shape of the lever coupling part 441 to guide the linear movement of the lever coupling part 441 . For example, the guide groove 4423 may be formed in a direction parallel to the longitudinal direction of the dust container body 44212 and may be formed in a groove shape having a predetermined curvature.

With this configuration, when the compression lever 420 is moved downward by an external force, the lever coupling portion 441 may move linearly along the guide groove 4423 .

The compression rod entry/exit hole 4424 may mean a space formed by opening the lower side of the housing body 4421 . That is, the housing body 4421 is formed with an open lower side, and the compression rod 443 moving in association with the linear movement of the compression lever 420 can enter and exit the open lower space of the housing body 4421 . have.

With this configuration, when the compression lever 420 moves linearly, at least a part of the compression rod 443 may be exposed to the outside of the dust container 400 (see FIGS. 7 and 8 ).

And, the second compression rod 4432 is formed in a rod shape, both ends are formed in a D-cut shape, one end is inserted and coupled to the compressor 430 , and the other end is inserted into the rod coupling portion 4433 . can be combined. In this case, the second compression rod 4432 may have a shorter length than the first compression rod 4431 .

Meanwhile, the second compression rod 4432 may penetrate the dust container body 410 . That is, one end of the second compression rod 4432 is disposed in the inner space of the dust container body 410 and is coupled to the compressor 430 , and the other end of the second compression rod 4432 is of the dust container body 410 .

In addition, there is an effect of maintaining the cleanliness of the dustbin 400 by minimizing the space in which dust is trapped inside the dustbin body 410 .

The first compression rod 4431 and the second compression rod 4432 may be inserted and coupled to the rod coupling portion 4433 .

The spring 444 may accommodate the support rod 445 therein, and elastically support the lower surface of the lever coupling portion 441 . For example, the spring 444 may be a coil spring.

The support rod 445 may pass through the lever coupling part 441 to be coupled to the delivery unit housing 442 , and may guide the linear movement of the lever coupling part 441 . Specifically, the support rod 445 may be fixedly coupled to the upper surface of the delivery unit housing 442 by passing through the rod through hole 4415 formed in the lever coupling portion 441 . In this case, the outside of the support rod 445 may be provided so that the spring 444 surrounds.

With this configuration, when an external force is applied to the compression lever 420 , the lever coupling portion 441 may compress the spring 444 while linearly moving downward along the support rod 445 . And, when the external force applied to the compression lever 420 disappears, the restoring force of the spring 444 is applied to the lever coupling part 441, and the compression lever 420 and the lever coupling part 441 can be returned to their original positions. have.
