[0037] Hereinafter, the vacuum cleaner of the present specification will be described with reference to the attached drawings.

[0038] FIG. 1 shows a schematic diagram of a vacuum cleaner according to one embodiment of the present invention, FIG. 2 shows a front view of a vacuum cleaner body according to one embodiment of the present invention, and FIG. 3 shows a cross-sectional view of a vacuum cleaner body according to one embodiment of the present invention.

[0039] Meanwhile, in this specification, "object to be cleaned" can be understood to mean not only the floor surface of a living room or room, but also a cleaning surface such as a carpet.

[0040] Referring to FIGS. 1 to 3, a vacuum cleaner (1) according to one embodiment of the present invention may include a vacuum cleaner body (100) having a suction motor (140) for generating suction force, a suction module (300) connected to the vacuum cleaner body (100) for sucking air and foreign matter of a cleaning object, and an extension tube (200) connecting the vacuum cleaner body (100) and the suction module (300).

[0041] The structure of the vacuum cleaner body (100) is described as follows.

[0042] Meanwhile, in one embodiment of the present invention, directions can be defined based on the extension tube (200). For example, downward may be the direction in which the suction module (300) is positioned based on the extension tube (200), and upward may mean the direction in which the handle (500) is positioned based on the extension tube (200) or the direction in which the main body of the vacuum cleaner (100) is positioned based on the extension tube (200). That is, the suction module (300) may be connected to the lower end of the extension tube (200), and the handle (500) may be connected to the upper end.

[0043] Additionally, the vacuum cleaner body (100) and the handle (500) may be arranged along the front-rear direction, where the front may be the direction in which the vacuum cleaner body (100) is arranged relative to the extension part (512) described later, and the rear may be the direction in which the handle (500) is arranged relative to the extension part (512). However, depending on the user's convenience, the vacuum cleaner body (100) may be arranged at the rear of the extension part (512) and the handle (500) may be arranged at the front of the extension part (512).

[0044] Additionally, when looking at the vacuum cleaner body (100) from the handle (500), the direction positioned on the right can be called the right, and the direction positioned on the left can be called the left.

[0045] The vacuum cleaner (1) may include a vacuum cleaner body (100). The vacuum cleaner body (100) may form an internal air passage that guides the sucked-in air to be discharged to the outside.

[0046] Specifically, the vacuum cleaner body (100) may include a body housing (110), a suction part (120), a dust separation part (130), a suction motor (140), an air discharge cover (150), a dust bin (170), a handle (500), a battery housing (180), and a battery (190).

[0047] The main body housing (110) can form the exterior of the vacuum cleaner body (100). The main body housing (110) can provide a space to accommodate the suction motor (140), dust separator (130), and pre-filter (145) inside. For example, the main body housing (110) can be configured in a shape similar to a cylinder.

[0048] The suction part (120) may protrude outward from the main body housing (110). For example, the suction part (120) may be formed in a cylindrical shape with an open interior. The suction part (120) may be coupled with an extension tube (200). The suction part (120) may provide a passage through which air containing dust can flow.

[0049] The specific configuration and effects of the suction part (120) will be described in detail later.

[0050] The dust separation unit (130) is connected to the suction unit (120) and is configured to apply the principle of a dust collector using centrifugal force to separate dust sucked into the interior of the vacuum cleaner body (100) through the suction unit (120). The space inside the dust separation unit (130) can be connected to the space inside the dust bin (170).

[0051] For example, the dust separation unit (130) may include a dust container (170) and may be equipped with a primary cyclone unit (131) and a secondary cyclone unit (132) capable of separating dust by cyclone flow. Additionally, the space inside the dust separation unit (130) may be in communication with a flow path formed in the suction unit (120). Accordingly, air and dust sucked in through the suction unit (120) flow spirally along the outer surface of the dust separation unit (130). Thus, cyclone flow can occur in the space inside the dust separation unit (130).

[0052] The suction motor (140) can be positioned on the flow path to generate a flow force that moves air within the flow path. The suction motor (140) can generate a suction force that sucks in air. Meanwhile, in this embodiment, a virtual motor axis line (V1) can be formed by extending the central axis of the suction motor (140). At this time, the motor axis line (V1) may be a virtual line connecting the centers of gravity of each plane that appear when the suction motor (140) is cut radially along the axial direction.

[0053] The suction motor (140) may include a motor shaft and an impeller that rotates according to the rotation of the motor shaft. Accordingly, air flow force can be generated according to the rotation of the impeller. As a result, the suction motor (140) can generate suction force by rotation.

[0054] The suction motor (140) may include, for example, an annular stator, a shaft penetrating the center of the stator, and a rotor axially mounted on the shaft and generating rotational force by the stator. Meanwhile, in this embodiment, the suction motor (140) uses a BLDC motor (brushless direct current motor; BLDC motor), but is not limited thereto and various types of motors may be applied.

[0055] The vacuum cleaner (1) may include a pre-filter (145) that filters air before it is sucked into the suction motor (140). The pre-filter (145) may be positioned, for example, so that a portion of it surrounds the impeller. Air in the suction path may pass through the pre-filter (145), for example, to reach the impeller. The pre-filter (145) may be positioned inside the vacuum cleaner body (100). The pre-filter (145) may be positioned below the air discharge cover (150). The user may remove the pre-filter (145) from inside the vacuum cleaner body (100) by separating the air discharge cover (150) from the body housing (110).

[0056] The vacuum cleaner body (100) may include an air guide (not shown) that guides air discharged from the dust separation unit (130). The air guide may be positioned between the body housing (110) and the housing of the suction motor (140).

[0057] According to this configuration, air and dust sucked in through the passage inside the suction section (120) by the operation of the suction motor (140) can be separated from each other by flowing through the passage inside the dust separation section (130), for example. The air from which dust has been separated in the dust separation section (130) can flow upward and can be introduced into the suction passage inside the fan drive section. The suction passage can guide the air toward the pre-filter (145). The air that has passed through the pre-filter (145) and the impeller sequentially can be introduced into the exhaust passage and, after passing through the HEPA filter (153), can be discharged to the outside through the exhaust ports (151, 152).

[0058] Here, the intake passage within the fan drive unit is connected to the passage within the dust separation unit (130), and air passing through the dust separation unit (130) can flow through it. The intake passage within the fan drive unit can be formed to allow air passing through the dust separation unit (130) to flow to the impeller.

[0059] Meanwhile, the vacuum cleaner (1) according to an embodiment of the present invention may include a printed circuit board (PCB) (not shown) for controlling a suction motor (140). The printed circuit board may be placed between the suction motor (140) and the dust separation unit (130), or between the suction motor (140) and the air discharge cover (150), but is not limited thereto.

[0061] The air exhaust cover (150) can form the upper exterior of the vacuum cleaner body (100) and can cover the upper part of the suction motor (140).

[0062] An air exhaust cover (150) can be placed on one side in the axial direction of the main body housing (110).

[0063] In the air discharge cover (150), an exhaust port (151) may be formed through which air within the airway is discharged to the outside of the vacuum cleaner body (100).

[0064] The exhaust port (151) may be positioned to face a specific direction, for example. For example, a plurality of exhaust ports (151) may be divided from one another in a circumferential direction. A plurality of exhaust ports (151) may be arranged spaced apart from one another along the circumferential direction.

[0065] Additionally, the air exhaust cover (150) may additionally be provided with a side exhaust port (152).

[0066] The air exhaust cover (150) can, for example, form the exterior of the upper outer surface of the vacuum cleaner body (100), and the side exhaust ports (152) can be formed in multiple numbers on the outer surface of the air exhaust cover (150) and arranged at a certain distance from each other along the circumferential direction.

[0067] Accordingly, the air inside the Euro can be discharged upward through the exhaust port (151) and also radially through the side exhaust port (152).

[0068] Additionally, the air exhaust cover (150) may only have a side exhaust port (152) formed therein, which prevents air within the flow path from being discharged to the outside and directed toward the user.

[0069] The air exhaust cover (150) may accommodate a filter for filtering air before it is discharged through the exhaust port (151) and the side exhaust port (152). For example, the air exhaust cover (150) may accommodate a HEPA filter (153).

[0070] Air passing through the intake motor (140) can be discharged to the outside through the exhaust port (151) and the side exhaust port (152) after passing through the HEPA filter (153). The HEPA filter (153) can be placed on the exhaust path.

[0071] A filter receiving space for accommodating a HEPA filter (153) may be formed in the air exhaust cover (150). The filter receiving space may be an inner space of the side exhaust port (152) and may be formed so that the lower side is open, allowing the HEPA filter (153) to be accommodated at the lower side of the air exhaust cover (150).

[0072] The exhaust port (151) may be formed to face the HEPA filter (153). For example, the HEPA filter (153) may be positioned below the exhaust port (151). The HEPA filter (153) may be positioned to extend circumferentially along the exhaust port (151), for example. Additionally, the side exhaust port (152) may be positioned to surround the HEPA filter (153).

[0073] The handle (500) can be grasped by a user. The handle (500) can be positioned on the outside of the main body housing (110). For example, the handle (500) can be formed in a shape similar to a cylinder. Alternatively, the handle (500) can be formed in a curved cylinder shape.

[0074] A control unit (not shown) may be placed on the handle (500). The control unit may be placed in the upper area of ​​the handle (500). The user can input a command to operate or stop the vacuum cleaner (1) through the control unit.

[0075] The dust bin (170) may be positioned on the other side of the axial direction of the main body housing (110). That is, the dust bin (170) may be positioned on the lower side of the main body housing (110), may be detachably coupled to the main body housing (110), or may be provided integrally with the main body housing (110). The dust bin (170) may accommodate a dust separation unit (130) inside. The dust bin (170) may be included in the dust separation unit (130), communicate with the suction unit (120), and may form a primary cyclone flow inside.

[0076] Also, the dust container (170) may be a dust container that provides a space for storing dust separated from the dust separation unit (130), and may be equipped with a primary dust collection unit (171) and a secondary dust collection unit (172) inside.

[0077] For example, the dust bin (170) may be formed in a shape similar to a cylinder and provided so that the lower side can be opened. In this case, a discharge cover (173) is provided on the lower side of the dust bin (170) so that the lower side of the dust bin (170) can be selectively opened.

[0078] The discharge cover (173) may be provided to open and close the lower side of the dust bin (170). The discharge cover (173) may be rotatably connected to the lower side of the dust bin (170). The discharge cover (173) may be hinge-connected to the dust bin (170) so that the lower side of the dust bin (170) can be opened and closed by rotational movement.

[0079] Meanwhile, according to an embodiment, the dust bin (170) may further include a dust bin compression lever (not shown) and a compressor (not shown) that move up and down within the dust bin (170) and drop dust.

[0080] A dust bin compression lever may be positioned outside the dust bin (170) or dust separator (130), positioned to move up and down, and connected to a compressor. This dust bin compression lever may move downward together with the compressor by an external force and return to its original position by an elastic member (not shown).

[0081] The compressor can be placed inside the dust container (170) or the dust separation unit (130) and can move up and down within the dust container (170) to compress the dust inside the dust container (170) downward. Additionally, when the discharge cover (173) is separated from the dust container (170) and the bottom of the dust container (170) is opened, the compressor can move from the top to the bottom of the dust container (170) to remove foreign substances, such as residual dust, inside the dust container (170). By doing so, the suction power of the vacuum cleaner can be improved by ensuring that no residual dust remains inside the dust container (170). Furthermore, by ensuring that no residual dust remains inside the dust container (170), odors caused by residue can be removed.

[0082] A battery (190) can be accommodated in the battery housing (180). The battery housing (180) can be placed on the handle (500), for example, and can be detachably coupled to the handle (500).

[0083] For example, the battery housing (180) may be integrally provided with the battery (190) housed inside. The battery (190) is configured to supply power to the vacuum cleaner (1). Specifically, the battery (190) can supply power to the suction motor (140) and can supply power to electronic circuits and electronic components, etc. through wires built into the vacuum cleaner (1). In addition, the battery (190) can supply power to the suction module (300).

[0084] The specific configuration and effects of the battery (190) and battery housing (180) will be described in detail later.

[0086] Meanwhile, the vacuum cleaner (1) may include an extension tube (200).

[0087] The extension tube (200) can be combined with the vacuum cleaner body (100) and the suction module (300). One end of the extension tube (200) can be detachably connected to the suction part (120). And, the other end of the extension tube (200) can be detachably connected to the suction module (300).

[0088] For example, the extension tube (200) may be formed in a long cylindrical shape. Thus, the internal space of the extension tube (200) may be in communication with the internal space of the cleaning module (300). Additionally, the extension tube (200) may be in communication with the suction path formed in the suction part (120) of the vacuum cleaner body (100).

[0089] When suction power is generated through the suction motor (140), suction power can be provided to the suction module (300) through the suction part (120) and the extension tube (200). Accordingly, external dust and air can be introduced into the vacuum cleaner body (100) through the cleaning module (300) and the extension tube (200). Additionally, dust and air introduced through the suction module (300) can be introduced into the vacuum cleaner body (100) after passing through the extension tube (200). Furthermore, dust and air introduced into the vacuum cleaner body (100) and passing through the suction part (120) can be separated in the dust separation part (130), after which the dust is stored in the dust bin (170) and the air can be discharged to the outside through the air discharge cover (150).

[0091] The suction module (300) can move along the floor surface and suck up dust present on the floor surface. The suction module (300) can be connected to the vacuum cleaner body (100) through the extension tube (200).

[0092] For example, the suction module (300) may be equipped with an agitator capable of guiding dust from the floor surface to the suction port by rotation. Alternatively, the suction module (300) may be further equipped with a mop that wipes the floor surface by rotation.

[0093] Meanwhile, although not shown, the suction module (300) can be directly connected to the main body of the vacuum cleaner (100) without the extension tube (200).

[0095] Meanwhile, the present invention places the suction part (120) inside the handle (500) to increase space utilization. That is, the main body housing (110) has the handle (500) placed on one side, and the suction part (120) can be formed inside the handle (500). The main body housing (110) is formed to have a roughly cylindrical shape, and only the handle (500) is placed on the outside thereof, thereby providing a simple exterior design.

[0096] Additionally, the main body housing (110) may be provided with an inlet hole (111) formed through the inner surface and the outer surface of the outer wall to which the handle (500) is connected. The internal space of the main body housing (110) may be connected to the internal space of the handle (500) through the inlet hole (111).

[0097] The inlet hole (111) can be positioned, for example, between the suction motor (140) and the dust separation unit (130), and can be formed so that air passing through the inlet hole (111) flows along the inner surface of the dust container (170) toward the discharge cover (173). That is, the air passing through the inlet hole (111) can flow cyclone downwards.

[0098] Accordingly, the main body housing (110) has a handle (500) connected between the suction motor (140) and the dust separation unit (130), and the part of the main body housing (110) where the handle (500) is connected can be positioned below the side exhaust port (152). That is, the side exhaust port (152) is positioned above the handle (500).

[0099] The handle (500) is provided with a handle body (510) that is connected to the main body housing (110) and the extension tube (200) and forms a suction part (120) inside. The suction part (120) is connected to an inlet hole (111) so that the internal space of the extension tube (200) can communicate with the internal space of the main body housing (110). The handle body (510) is provided with an extension tube (200) at one end and a main body housing (110) at the other end. Here, the extension tube (200) can be detachably installed at one end of the handle body (510), and the other end of the handle body (510) can be provided to be integrally connected to the main body housing (110) or coupled to the main body housing (110).

[0100] The handle body (510) forms the exterior of the handle (500) and is formed in a column shape so that a user can grasp it, and a suction part (120) may be formed inside. The part of the handle body (510) connected to the main body housing (110) is not positioned perpendicular to the motor axis (V1) of the suction motor (140) and may be provided in a straight line or a curved shape. That is, the part of the handle body (510) connected to the main body housing (110) may be provided in a straight line shape that slopes downward toward the inlet hole (111) of the main body housing (110), or in a curved shape that slopes downward toward the inlet hole (111) of the main body housing (110). Accordingly, virtual lines (L1, L3) extending the center axis of the end connected to the main body housing (110) are arranged to be spaced apart from the suction motor (140) at a predetermined distance.

[0101] For example, the handle body (510) may be composed of a connecting part (511) and an extension part (512).

[0102] The connecting part (511) has an extension tube (200) connected to one end and can be arranged along the direction in which the extension tube (200) is arranged. In this embodiment, a virtual connecting part axis line (V2) can be formed by extending the central axis of the connecting part (511). The connecting part axis line (V2) can be arranged parallel to the motor axis of the suction motor (140). That is, the connecting part axis line (V2) is arranged parallel to the motor axis line (V1) but can be spaced apart at a certain distance.

[0103] The connecting part (511) is positioned spaced apart from the vacuum cleaner body (100), but can be positioned spaced apart from the vacuum cleaner body (100) by a distance sufficient for the user to grip the handle (500). An extension part (512) and a support part (520) can be positioned between the connecting part (511) and the vacuum cleaner body (100). Accordingly, the handle (500) forms a space bordered by the outer surface of the vacuum cleaner body (100), the connecting part (511), the extension part (512), and the support part (520), allowing the user to easily grip the handle (500).

[0104] Additionally, the connecting part (511) may be provided with an extension tube connecting part (511a) that is connected to an extension tube (200) at one end. The extension tube connecting part (511a) is detachably connected to the extension tube (200).

[0105] The handle (500) may be provided with a battery mounting portion (530) on the side opposite to the side facing the main body (100) of the connecting portion (511). The battery mounting portion (530) is detachably coupled to a battery housing (180) or a battery (190). The battery mounting portion (530) is provided with a protrusion (531) arranged in an up-and-down direction to allow the battery housing (180) or the battery (190) to be mounted more easily.

[0106] The battery housing (180) may be provided in the form of a rectangular block, and the battery (190) may be integrally embedded or detachably accommodated inside. When the battery (190) is integrally embedded, at least one battery (190) is installed inside the battery housing (180). Alternatively, when the battery (190) is detachably accommodated, the battery housing (180) may be configured with one side open so that the battery (190) can be detached through the open part.

[0107] At this time, the battery housing (180) is arranged along the vertical direction, and the upper end is located lower than the upper end of the main body housing (110), and the lower end may be located higher than the lower end of the main body housing (110).

[0108] In this way, the main body housing (110) and the battery housing (180) are positioned at the front and rear of the handle (500), respectively, to prevent the weight of the vacuum cleaner (1) from being unevenly distributed. That is, the suction motor (140) is positioned on one side of the handle (500) and the battery (190) is positioned on the other side so that the overall weight of the vacuum cleaner (1) is balanced.

[0109] The extension portion (512) may be formed by extending toward the main body housing (110) from the other side of the connecting portion (511). For example, the extension portion (512) may be formed by protruding in a straight line from the other side of the connecting portion (511). One end of the extension portion (512) may be connected to the connecting portion (511) and the other end may be connected to the inlet hole (111) to allow the extension tube (200) to communicate with the internal space of the main body housing (110).

[0110] This extension (512) may be provided with a gripping projection (not shown) formed to protrude so that the user's finger rests on the outer surface, and may substantially be the part that the user grips when using the vacuum cleaner (1).

[0111] The extension portion (512) may be formed to extend from the other side of the connecting portion (511) to the inlet hole (111) as shown in the drawing. The other end of the connecting portion (511) may be located above the inlet hole (111), and the extension portion (512) may be provided in a straight line shape that slopes downward toward the inlet hole (111).

[0112] Accordingly, the extension axis (L1), which extends the central axis of the extension part (512), can be arranged to intersect the motor axis (V1), and the extension axis (L1) can be arranged to be spaced apart from the suction motor (140) at a predetermined distance. That is, the extension axis (L1) passes through the main body housing (110) but does not come into contact with the suction motor (140). The suction motor (140) can be located above the extension axis (L1) inside the main body housing (110).

[0113] Here, the extension axis (L1) may be a virtual line extending the center axis of the end connected to the main body housing (110) of the extension (512), that is, a virtual line connecting the center of gravity of each cross section of the extension (512).

[0114] In addition, the connection portion between the connecting portion (511) and the extension portion (512) can be formed rounded so that the internal flow path does not bend abruptly.

[0115] Meanwhile, the interior of the handle body (510) may include a flow path connecting the extension tube (200) and the main body housing (110). That is, the handle body (510) may form a suction part (120) inside, and the suction part (120) may include a first flow path (121) and a second flow path (122).

[0116] The first flow path (121) is spaced apart from the main body housing (110) and can be connected to the internal space of the extension tube (200). The second flow path (122) connects the first flow path (121) and the internal space of the main body housing (110) and can be positioned between the connecting part (511) and the main body housing (110). The second flow path (122) can be positioned to intersect the first flow path (121). Additionally, the first flow path (122) can be positioned to intersect the long axis of the main body housing (110), and, for example, can be positioned in a straight line shape intersecting the long axis of the main body housing (110).

[0117] That is, the first Euro (121) can be formed inside the connecting part (511) and the second Euro (122) can be formed inside the extension part (512).

[0118] Here, the major axis of the main body housing (110) may be a virtual line connecting the centers of gravity of each plane that appear when the main body housing (110) is cut radially along the axial direction, and may be formed parallel to the motor axis line (V1) of the suction motor (140). Also, the major axis of the main body housing (110) may be the center axis of the primary cyclone flow of the dust separation unit (130).

[0119] Accordingly, air sucked in through the extension tube (200) flows through the first flow path (121) and the second flow path (122) and can be introduced into the internal space of the main body housing (110) through the inlet hole (111). That is, the air sucked in through the extension tube (200) flows through the internal space of the handle (500) before flowing into the internal space of the main body housing (110).

[0120] Additionally, the handle (500) may further be provided with a support member (520). The support member (520) is positioned between the connecting member (511) and the main body housing (110) to support the handle body (510). The support member (520) is formed to protrude from one side of the connecting member (511) toward the main body housing (110) and may be provided in the form of a solid frame or in the form of a hollow frame for weight reduction. However, the support member (520) is not connected to the internal space of the handle body (510).

[0121] For example, such a support member (520) can be formed parallel to an extension member (512). That is, a virtual support member axis line (L2) can be formed by extending the central axis of the support member (520), and the support member axis line (L2) can be arranged parallel to the extension member axis line (L1).

[0123] Meanwhile, FIG. 4 shows a front view of a vacuum cleaner body according to another embodiment of the present invention, and FIG. 5 shows a cross-sectional view of a vacuum cleaner body according to another embodiment of the present invention.

[0124] Referring to FIGS. 4 and FIGS. 5, a handle (1500) according to another embodiment of the present invention will be described.

[0125] The handle (1500) is provided with a handle body (1510) that is connected to the main body housing (110) and the extension tube (200) and forms a suction part (1120) inside. The handle body (1510) may be composed of a connecting part (1511) and an extension part (1512) that is bent. That is, the suction part (1120) may include a first fluid path (1121) arranged along the extension tube (200) and a second fluid path (1122) in a curved shape connecting the first fluid path (1121) and the internal space of the main body housing (110).

[0126] The connecting part (1511) has an extension tube (200) connected to one end and can be positioned parallel to the motor axis of the suction motor (140). That is, the connecting part (1511) can be positioned so that a virtual connecting part axis line (V3) extending from the center axis is parallel to the motor axis line (V1).

[0127] Additionally, the connecting portion (1511) may be provided with an extension tube connecting portion (1511a) that is connected to an extension tube (200) at one end. The extension tube connecting portion (1511a) is detachably connected to the extension tube (200).

[0128] The handle (1500) may be provided with a battery mounting portion (1530) on the side opposite to the side facing the vacuum cleaner body (100) of the connecting portion (1511). The battery mounting portion (1530) may be positioned at the other end of the connecting portion (1511), and, for example, may be positioned on the upper side of the connecting portion (1511). Additionally, the battery mounting portion (1530) is provided with a protrusion (1531) positioned in the vertical direction so that the battery housing (180) or the battery (190) can be mounted more easily.

[0129] The battery mounting portion (1530) may further be provided with a connecting rib (1532) that connects the extension portion (1512) and the protrusion portion (1531). The connecting rib (1532) may be composed of a curved surface that connects the extension portion (1512) and the protrusion portion (1531), and supports the protrusion portion (1531) while allowing the user to grip the extension portion (1512) more stably.

[0130] The extension portion (1512) is formed by extending from the other end of the connecting portion (1511). For example, it may be formed in the shape of a curved tube that protrudes toward the opposite side of the support portion (1520) to be described later, so as to be formed to communicate with the main body housing (110) from the other side of the connecting portion (1511).

[0131] Additionally, a virtual extension tangent (L3) can be formed along the tangential direction at the end of the extension part (1512) connected to the main body housing (110), and the extension tangent (L3) can be formed so as not to come into contact with the suction motor (140). That is, the extension tangent (L3) is positioned to be spaced apart from the suction motor (140) at a predetermined distance, and the suction motor (140) can be located above the extension tangent (L3) inside the main body housing (110).

[0132] Here, the extension part (1512) is formed in the shape of a curved tube, and connecting the centers can form a curved centerline. Also, the tangent line that touches the end point connected to the main body housing (110) of the curved centerline may be the tangent line (L3) of the extension part.

[0133] Additionally, the suction portion (1120) may include a first flow path (1121) and a curved second flow path (1122). The second flow path (1122) is formed inside the extension portion (1512) and is formed to have a gentle curve from the first flow path (1121) to the inlet hole (111). Accordingly, the connection portion between the first flow path (1121) and the second flow path (1122) and the connection portion between the second flow path (1122) and the internal space of the main body housing (110) are not sharply bent, and losses due to flow can be minimized.

[0134] Additionally, the extension part (1512) is provided in the shape of a curved tube protruding to the opposite side of the support part (1520), so that the handle (1500) is provided in a round shape in appearance, and the user's grip can be improved.

[0135] Additionally, the handle (1500) may further be provided with a support member (1520). The support member (1520) is positioned between the connecting member (1511) and the main body housing (110) to support the handle body (1510).

[0136] For example, the support member (1520) may be provided in the form of a frame that slopes toward the extension member (1512) as it moves from the connecting member (1511) toward the main body housing (110). That is, the support member (1520) may form a virtual support member axis line (L4) that extends the central axis, and the support member (1520) may be arranged so that the support member axis line (L4) slopes upward as it moves toward the main body housing (110).

[0137] Although specific embodiments of the present invention have been described and illustrated above, the present invention is not limited to the described embodiments, and those skilled in the art will understand that various modifications and variations can be made to other specific embodiments without departing from the spirit and scope of the present invention. Accordingly, the scope of the present invention should not be determined by the described embodiments but by the technical concept described in the claims. Explanation of the symbols
