Description

FIELD OF THE INVENTION

[0001] The present disclosure relates to a cleaning device.

BACKGROUND OF THE INVENTION

[0002] Cleaning devices can be divided into manual cleaning devices that the user personally moves during cleaning, and automatic cleaning devices that automatically move during cleaning.

[0003] Manual cleaning devices can be divided, depending on the types, into container-type cleaning devices, vertical-type cleaning devices, manual cleaning devices and rod-type cleaning devices.

[0004] Hand-held cleaning devices mainly include a suction assembly, a housing, and a handle.

[0005] An extension tube having a suction nozzle may be connected to the suction assembly. In addition, a battery for supplying power may be located in the handle.

[0006] When the suction nozzle includes a carpet cleaning unit and an electric motor for rotating the cleaning unit, it is assumed that the electric motor is powered by a battery.

[0007] In order to supply power to the electric motor from the battery located in the handle, the battery must be connected to the electric motor using the supply wire and the control signal wire. The wires are connected to the suction unit through the housing.

[0008] The main body may include a dust collector that stores dust, and the dust collector may be transparent or translucent, so that the user can visually check the dust in the dust collector.

[0009] However, the wires pass through the main body, so it is necessary to prevent the wires from being visible from the outside through the dust collector.

[0010] Moreover, in the prior art, a hand-held vacuum cleaner was disclosed in Korean Patent No. 10-1127088 (registered March 8, 2012).

Disclosure of invention

Technical problem

[0011] The present disclosure provides a cleaning device whose wires are not visible from the outside through a transparent or translucent dust collector.

[0012] The present disclosure provides a cleaning device in which the cap for preventing wires from exiting to the outside has a terminal for electrically connecting between the main body and the handle assembly.

[0013] The present disclosure provides a cleaning device in which the terminal of the main body and the terminal of the handle on the handle assembly are easily connected by a cover.

[0014] The present disclosure provides a cleaning device in which the possibility of capsizing of the main body when connecting the handle terminal to the main body terminal is prevented.

Technical solution

[0015] The cleaning device includes a suction unit that directs air and dust, a main body that is connected to the suction unit and has a dust separation unit that separates dust from the air, and a dust collector storing dust separated by the dust separation unit, wherein at least a part of the dust bag is transparent or translucent, a handle assembly that is connected to the main body and has a battery, a power component that is located in the main body to supply battery power, a wire a, which are connected to the component for receiving power, and a cover that is connected to the main body and is located between the main body and the wires to prevent the wires from being visible from the outside of the dust collector.

[0016] The cleaning device includes a pen assembly that has a printed circuit board assembly, a battery that is removably coupled to the pen assembly and connected to the printed circuit board assembly when connecting the battery to the pen assembly, a main body that has a component for receiving power for its power supply from the battery and which is combined with the handle assembly, the handle terminal, which is located on the handle assembly and connected to the circuit board assembly, and the main body terminal, which is mechanically connected to the handle terminal when connecting the handle assembly to the main body and when it is connected to power receivers via wires.

Positive results

[0017] According to the present invention, since the lid is located on a transparent or translucent dust collector and the wires are directed to the terminal of the main body by the lid, the lid closes the wires, and thus, the wires are not visible from the outside of the dust collector.

[0018] In addition, since the terminal of the main body is supported by a cover, the terminal of the main body is not visible from the outside of the dust collector.

[0019] In addition, the handle assembly has a handle terminal connected to a terminal of the main body, and slidably connected to the cover. Accordingly, the terminal of the main body and the battery terminal can be connected by connecting the handle assembly to the cover.

[0020] In addition, since the terminal of the main body is connected to the connecting ribs and held in this position, the terminal of the main body is not pressed when the handle terminal is connected to the main body terminal, so improper assembly of the handle terminal and the main body terminal can be prevented.

[0021] In addition, since the terminal of the main body is supported by the terminal support, the terminal of the main body is not pressed when connecting the handle terminal to the terminal of the main body, thus, improper assembly of the handle terminal and the terminal of the main body can be prevented.

[0046] As shown in FIGS. 1-5, the cleaning device 1 according to an embodiment of the present invention may include a main body 2.

[0047] The cleaning device 1 may further include a suction unit 5 connected to a front side of the main body 2. The suction unit 5 may direct dust containing air to the main body 2.

[0048] The cleaning device 1 may further include a handle unit 3 connected to the main body 2. The handle unit 3 may be located opposite the suction unit 5 on the main body 2.

[0049] That is, the main body 2 may be located between the suction assembly 5 and the handle assembly 3.

[0050] The main body 2 may include a first body 10 and a second body 12 on the first body 10.

[0051] The first housing 10 and the second housing 12 may be, although not limited to, formed in a cylindrical shape.

[0052] The suction assembly 5 can be connected to the main body 2 so that the center of the suction assembly 5 is located approximately at the boundary between the first housing 10 and the second housing 12.

[0053] The main body 2 may further include a dust separation unit that separates dust from air drawn in through the suction unit 5.

[0054] The dust separation unit may include a first cyclone unit 110 that can separate dust, for example using a cyclone stream. The first housing 10 includes a first cyclone assembly 110 in this structure.

[0055] Air and dust sucked through the suction unit 5 pass in a spiral along the inside of the first cyclone unit 110.

[0056] The axis of the cyclone flow in the first cyclone assembly 110 may extend vertically.

[0057] The dust separator assembly may further include a second cyclone assembly 130 that secondarily separates dust from air discharged from the first cyclone assembly 110. A second cyclone assembly 130 may be located within the first cyclone assembly 110 to minimize the size of the dust separation assembly. The second cyclone assembly 130 may include a plurality of cyclone bodies arranged in a row.

[0058] As another example, the dust separation unit may include one cyclone unit in which the axis of the cyclone stream may also extend vertically.

[0059] The first housing 10 functions as a dust collector that stores dust separated by cyclone assemblies 110 and 130. The upper part of the first housing 10 is the first cyclone assembly 110, and the lower part of the first housing 10 is a dust collector. The first housing 10 may be partially or completely transparent or translucent to allow the user to visually check the amount of dust in the dust collector.

[0060] The main body 2 may further include a cover 16 for opening / closing the lower part of the first body 10. The housing cover 16 may open / close the first body 10 by rotation. A key 18 for pivoting the housing cover 16 may be located on the first housing 10.

[0061] The hinge 162 of the housing cover 16 may be connected to the connecting parts 620 of the hinge of the battery case 60.

[0062] At least a portion of the second cyclone assembly 130 may be located inside the first housing 10.

[0063] A dust storage guide 124, which directs the dust separated by the second cyclone assembly 130, can be located in the first housing 10. A dust storage guide 124 can be connected to the lower part of the second cyclone assembly 130 in contact with the upper part covers 16 of the housing.

[0064] The dust storage guide 124 may divide the inner region of the first housing 10 into a first dust storage portion 121 in which dust separated by a first cyclone assembly 110 is stored and a second dust storage part 123 in which dust separated by a second cyclone is stored node 130.

[0065] The inner region of the dust storage guide 124 is the second dust storage part 123, and the area between the dust storage guide 124 and the first housing 10 is the first dust storage part 121.

[0066] The housing cover 16 may open / close both the first dust storage part 121 and the second dust storage part 123.

[0067] The cleaning device 1 may further include a suction motor 20 for generating a suction force and a battery 40 for supplying power to the suction motor 20.

[0068] The suction motor 20 may be located in the second housing 12. At least a portion of the suction motor 20 may be located above the dust separation unit. Accordingly, the suction motor 20 is located above the first housing 10.

[0069] The suction motor 20 may communicate with the outlet of the second cyclone assembly 130.

[0070] For this purpose, the main body 2 may further include an exhaust guide 28 connected to the second cyclone assembly 130, and a flow guide 22 that communicates with the exhaust guide 28.

[0071] For example, the exhaust guide 28 is located on the second cyclone assembly 130, and the flow guide 22 is located above the exhaust guide 28.

[0072] In addition, at least a portion of the suction motor 20 is located inside the flow guide 22.

[0073] Accordingly, the axis of the cyclone flow in the first cyclone assembly 110 may pass through the suction motor 20.

[0074] When the suction motor 20 is located above the second cyclone assembly 130, air leaving the second cyclone assembly 130 can directly pass to the suction motor 20, so that the channel between the dust separation assembly and the suction motor 20 can be minimized.

[0075] The suction motor 20 may include a rotating impeller 200. The impeller 200 may be mounted on the shaft 202. The shaft 202 is located vertically.

[0076] An extension line from the shaft 202 (which may be regarded as the axis of rotation of the impeller 200) may extend through the first housing 10. The axis of rotation of the impeller 200 and the axis of the cyclone flow in the first cyclone assembly 110 may be located on the same line.

[0077] In accordance with the present invention, an advantage is provided that the channel through which the air exiting the dust separation unit, that is, the air exiting upward from the second cyclone assembly 130, passes to the suction motor 20, can be reduced, and the change air direction can be reduced, so that airflow loss can be reduced.

[0078] Since the loss of air flow is reduced, the suction force can be increased, and the life of the battery 40 for supplying power to the suction motor 20 can be increased.

[0079] The cleaning device 1 may further include an upper motor casing 26 covering a portion of the upper portion of the suction motor 20, and a lower motor casing 27 covering a portion of the lower portion of the suction motor 20. The lower motor casing 27 may be integral with the second housing 12 or may be connected to the second housing 12.

[080] The suction motor 20 may be located inside the motor housings 26 and 27, and the flow guide 22 may be located to close the upper motor housing 26.

[0081] At least a portion of the flow guide 22 may be spaced apart from the upper motor housing 26. In addition, at least a portion of the flow guide 22 may be located at a distance from the second housing 12.

[0082] Accordingly, the first air channel 232 is formed by the inner side of the flow guide 22 and the outer side of the upper motor casing 26, and the second air channel 234 is formed by the outer side of the flow guide 22 and the inner side of the second housing 12.

[0083] The air leaving the second cyclone assembly 130 passes into the suction motor 20 through the first air channel 232, and the air leaving the suction motor 20 passes through the second air channel 234, and then the outside is exhausted. Accordingly, the second air channel 234 performs the function of an exhaust channel.

[0084] The handle assembly 3 may include a handle 30 for holding by a user and a battery case 60 under the handle 30.

[0085] The handle 30 may be located behind the suction motor 20.

[0086] Regarding the directions relative to the suction motor 20 in the cleaning device 1, the direction in which the suction unit 5 is located is the forward direction, and the direction in which the handle 30 is located is the back direction.

[0087] The battery 40 may be located behind the first housing 10. Accordingly, the suction motor 20 and the battery 40 may be located without vertical overlap with each other and may be located at different heights.

[0088] According to the present invention, since the suction motor 20, which is heavy, is located in front of the handle 30, and the battery 40, which is heavy, is located behind the handle 30, thus, the weight can be evenly distributed in the cleaning device 1 . Damage to the user's wrist can be prevented when the user performs the cleaning process with the handle 30 in his hand. That is, since the heavy components are distributed at the front and rear and at different heights in the cleaning device 1, concentration of the center of gravity of the cleaning device 1 on any one side can be prevented.

[0089] Since the battery 40 is located under the handle 30 and the suction motor 20 is located in front of the handle 30, there is no component above the handle 30. That is, the upper part of the handle 30 forms part of the appearance of the upper part of the cleaning device 1.

[0090] Accordingly, it is possible to prevent any component of the cleaning device 1 from coming into contact with the user's hand, while the user is carrying out the cleaning process with the handle 30 in his hand.

[0091] The handle 30 may include a first protruding portion 310 extending vertically for holding by the user, and a second protruding portion 320 extending to the suction motor 20 above the first protruding portion 310. The second protruding portion 320 may extend at least partially horizontally .

[0092] A stop 312 for preventing the movement of a user's hand holding the first protruding portion 310 in the longitudinal direction of the first protruding portion 310 (vertically in FIG. 2) may be formed on the first protruding portion 310. The stop 312 may extend to the suction assembly 5 from the first protruding portion 310.

[0093] The stop 312 is located at a distance from the second protruding portion 320. Accordingly, it is assumed that the user holds the first protruding portion 310 with a few fingers above the stop 312 and the remaining fingers under the stop 312.

[0094] For example, a stop 312 may be located between the index finger and the middle finger.

[0095] According to this arrangement, when the user holds the first protruding portion 310, the longitudinal axis A1 of the suction unit 5 can pass through the wrist of the user.

[0096] When the longitudinal axis A1 of the suction unit 5 passes through the wrist of the user and the hand of the user is extended, the longitudinal axis A1 of the suction unit 5 can essentially be aligned with the extended arm of the user. Accordingly, there is an advantage in this position in which the user uses minimal force when pushing or moving the cleaning device 1 with the handle 30 in his hand.

[0097] The handle 30 may include a control unit 326. For example, the control unit 326 may be located on the inclined surface of the second protruding portion 320. You can enter commands to turn on / off the cleaning device (suction motor) using the control unit 326. For example, commands can be entered to turn the suction motor on / off through the control unit 326. In addition, it is possible to control the magnitude of the suction force of the suction motor 20, which was turned on through the control unit 326.

[0098] The control unit 326 may be facing the user. The control unit 326 may be located opposite the stop 312 with a handle 30 between them.

[0099] The control unit 326 is located above the limiter 312. Accordingly, the user can easily operate the control unit 326 with his thumb with the first protruding portion 310 in his hand.

[00100] Furthermore, since the control unit 326 is located on the outside of the first protruding portion 310, it is possible to prevent the unexpected actuation of the control unit 326 when the user cleans with the first protruding portion 310 in his hand.

[00101] The battery case 60 may be located under the first protruding portion 310.

[00102] The battery 40 may be removably coupled to the battery case 60. For example, the battery 40 may be inserted into the battery case 60 from the bottom of the battery case 60.

[00103] The rear side of the battery case 60 and the rear side of the first protruding portion 310 can form a continuous surface. Accordingly, the battery case 60 and the first protruding portion 310 may be depicted as a separate unit.

[00104] When the battery 40 is inserted into the battery case 60, the bottom of the battery 40 can be opened to the outside. Accordingly, when the cleaning device 1 is located on the floor, the battery 40 may be in contact with the floor.

[00105] In accordance with this construction, it is an advantage that the battery 40 can be directly removed from the battery case 60.

[00106] In addition, since the bottom of the battery 40 extends outward, the bottom of the battery 40 can come into direct contact with the air on the outside of the cleaning device 1, so that the battery 40 can be cooled more efficiently.

[00107] The battery case 60 may include an outer case 600 and an inner case 610. The inner case 610 may be inserted under the outer case 600.

[0108] The inner casing 610 may be secured to one or more of the outer casing 600 and the first housing 10. In addition, the battery 40 may be connected to the inner casing 610.

[0109] According to the present invention, the inner casing 610 is inserted into the outer casing 600, and then the battery 40 is inserted to connect to the inner casing 610, thus, it is possible to prevent deformation of the outer casing 600 or to prevent damage to the outer casing 600 when inserting or disconnecting the battery 40 .

[0110] Obviously, it may be possible to perform as a whole the inner casing 610 with the outer casing 600 without forming with the possibility of separation of the inner casing 610.

[0111] The inner casing 610 may include a pair of hinge connecting parts 620 to which the hinge 162 of the housing cover 16 is connected. The joint parts 620 of the hinge can be located at a predetermined distance from each other.

[0112] The inner casing 628 may have charging table connection terminals 628 for charging a battery 40 connected to the inner casing 610. The charging table connection terminals 628 can be brought into contact with a charging table terminal (not shown) by placing the cleaning device 1 on the charging table .

[0113] The battery case 600 may have battery connection terminals 670 that are connected to battery terminals 490 on the battery 40 inserted in the battery case 60. Battery connection terminals 670 may be connected to battery terminals 490 through the top of battery 40.

[00114] As shown in FIG. 3, the cleaning device 1 may further include a filter assembly 50 having air outlets 522 for discharging air that has passed through the suction motor 20. For example, the air outlets 522 may include a plurality of openings, and the holes can be arranged in a circumferential direction.

[00115] The filter assembly 50 may be removably coupled to the upper portion of the main body 2. The filter assembly 50 may be removably inserted into the second housing 12.

[00116] When the filter unit 50 is connected to the main body 2, a part of the filter unit 50 is located outside the second body 12. Accordingly, a part of the filter unit 50 is inserted into the main body 2 through the open upper part of the main body 2, and the other part extends outward from the main body 2.

[00117] The height of the main body 2 can be substantially the same as the height of the handle 30. Accordingly, the filter assembly 50 projects upward from the main housing 2, so that the user can easily hold and separate the filter assembly 50.

[00118] When the filter assembly 50 is connected to the main body 2, air outlets 522 are located on the upper part of the filter assembly 50. Accordingly, the air leaving the suction motor 20 is discharged upward from the main body 2.

[00119] According to this embodiment, it is possible to prevent the passage of air leaving the air outlets 522 to the user while the user is carrying out a cleaning process using the cleaning device 1.

[00120] The main body 2 may further include a pre-filter 29 for filtering air passing into the suction motor 20. The pre-filter 29 may be located inside the flow guide 22. In addition, the pre-filter 29 is located above the upper casing 16 of the electric motor and can surround part of the upper casing 26 of the electric motor. That is, the upper motor housing 26 may include a filter support for supporting the pre-filter 29.

[00121] FIG. 6 is a view of a penless cleaning device according to an embodiment of the present invention, FIG. 7 is a view of a main body without a cap in accordance with an embodiment of the present invention, and FIG. 8 is an isometric view of a first housing in accordance with with an embodiment of the present invention.

[00122] As shown in FIGS. 6-8, the first housing 10 and the second housing 12 can be connected vertically to each other.

[00123] For this purpose, the first housing 10 has a first connecting portion 105, and the second housing 12 has a second connecting portion 122.

[00124] The first connecting portion 105 may be a protrusion formed on the outer side of the first housing 10. The second connecting portion 122 may extend downward from the bottom of the second housing 12. The second connecting portion 122 may be a hook that locks with the protrusion.

[00125] The first connecting portion 105 may be located at a predetermined distance downward from the upper end of the first housing 10, so that the second connecting portion 122 extending downward from the second housing 12 is connected to the first connecting portion 105.

[00126] The cover 70 may be connected to the first housing 10. The cover 70 may prevent the plurality of wires of the main housing 126 from being transmitted for transmitting control and / or power signals from the outside of the first housing 10 (or the outside of the dust collector 120).

[00127] The wires 126 and 127 of the main body can be connected to the terminal 80 of the main body. The wires 126 and 127 of the main body may include two first wires 126 of the main body connected to a terminal (not shown) on the suction unit 5, and two second wires 127 of the main body connected to the suction motor 20.

[00128] An extension tube connected to a suction nozzle having a rotating cleaning unit and an electric motor can be connected to a suction unit 5, wherein when the extension tube is connected to a suction unit 5, the electric motor is electrically connected to a terminal of the suction unit and can be powered from battery 40. Alternatively, a suction nozzle having a rotating cleaning unit and an electric motor can be connected directly to the suction unit 5, in which the electric motor is sucked she heads can also be supplied with power from the battery 40.

[00129] Some of the wires of the main body 126 and 127 may be inserted into the second body 12. The remaining wires 126 and 127 of the main body may extend downward from the second body 12, may be guided by the cover 70, and then may be connected to the terminal 80 of the main body.

[00130] The cover 70 may support a terminal 80 of the main body connected to wires 126 and 127 of the main body. Accordingly, the cover 70 can prevent the main body wire 80 from being visible from the outside of the first housing 10 (or the outer side of the dust collector 120).

[00131] The cover 70, although not limited to this, can be connected to the side opposite to the suction unit 5 on the first body 10. When the cover 70 is located opposite the suction unit 5 on the first case 10, it can be closed by the handle unit 3, thus , cover 70 cannot go out.

[00132] The first housing 10 may have a recessed contact surface on the outer surface of the first housing 10 for mounting the cover 70.

[00133] The contact surface may include a rounded first contact surface 101 and flat second contact surfaces 102 on both sides of the first contact surface 101.

[00134] The first housing 10 may further include a lid connecting hook 104 for connecting the lid 70.

[00135] The first housing 10 may further include a first connecting portion 105 to be connected to the second housing 12.

[00136] The lid connecting hook 104 can be positioned at a predetermined distance below the first connecting part 105. The lid connecting hook 104 can extend down under the first connecting part 105 to prevent interference between the second connecting part 112 and the lid hook 104 that has been connected to the first connecting part part 105.

[00137] Since the second contact surfaces 102 are located on both sides of the first contact surface 101, it is possible to prevent horizontal rotation of the cover 70 connected to the first housing 10 around the first housing 10.

[00138] The first housing 10 may include one or more locking ribs 103 to maintain a stable connection of the cover 70.

[00139] For example, the first housing 10 may include a plurality of locking ribs 103 to prevent up-down and left-right movement of the cover 70.

[00140] The locking ribs 103 may protrude from the first contact surface 101 of the first housing 10 and may be horizontally and vertically spaced apart.

[00141] For example, two horizontally positioned locking ribs 103 may extend from each other.

[00142] The ends 103a of at least some of the locking ribs 103 can be configured to exit to the second contact surface 102 at a predetermined distance from the second contact surface 102.

[00154] The lid body 710 may further include a groove 714 for passing the lid connecting hook 104, and a hook locking part 715 for locking the lid connecting hook 104 passing through the groove 714.

[00155] A groove 714 is located on the lower side of the receiving region 713. Therefore, in accordance with the present invention, the lid connecting hook 104 can be connected to the hook locking part 715 in series through the receiving region 713 and the groove 714. The second connecting part 122 of the second housing 12 can be inserted into the receiving region 713 without interference from the side of the cover body 710.

[00156] The receiving region 713 is an area located at a distance from both sides of the lid body 710, so when the second connecting portion 122 of the second housing 12 is inserted into the receiving region 713, the lid housing 710 cannot be moved horizontally by the second connecting part 122.

[00157] The lid body 710 may further include receiving regions 718 for ribs for accommodating the locking ribs 103 of the first housing 10, holding ribs 719 to prevent radial movement of the locking ribs 103 in the receiving regions 718 for the ribs from the first housing 10, and supporting sides 720 for ribs to support the locking ribs 103 in the receiving areas 718 for the ribs.

[00158] The holding ribs 719 may be located under the inlets 718a of the receiving regions 718 for the ribs.

[00159] The cover body 710 may further include second handle connecting parts 721 for connecting the handle assembly 3.

[00160] The second handle connecting parts 721 may include a first protruding portion 722 extending horizontally from the lid body 710, and a second protruding portion 723 extending upward from the first protruding portion 722.

[00219] FIG. 22 is a conceptual diagram showing connecting structures of a cleaning device according to the present invention.

[00220] As shown in FIGS. 4, 18 and 22, the present invention may include, as described above, a main body 2, a handle assembly 3, and a battery 40.

[00221] The cleaning device 1 according to the present invention has basically three connecting structures for supplying power.

[00222] The first connection structure is a structure for connecting the battery 40 and the handle assembly 3. The battery 40 is detachably connected to the handle assembly 3 in the present invention.

[00223] When connecting the battery 40 to the pen assembly 3, the battery 40 is connected to the main circuit assembly 340. The battery 40 and the handle assembly 3 are connected by mechanically connecting the battery terminal 490 and the battery connection terminal 670. Obviously, since the main circuit board assembly 340 is connected to the battery connection terminal 670 by wires, when the battery terminal 490 and the battery connection terminal 670 are connected, they are electrically connected, so that power from the battery 40 can be supplied to the main circuit assembly 340.

[00224] A second connecting structure of the present invention is a structure for connecting the handle assembly 3 and the main body 2.

[00225] When the handle assembly 3 is vertically slideable with the main body 2 and the main circuit board assembly 340 connected to the handle terminal 90, the handle terminal 90 and the main body terminal 80 are mechanically connected. Obviously, when the handle terminal 90 and the main body terminal 80 are connected, they are electrically connected, so that power can be supplied to the main body terminal 80 through the handle terminal 90 from the host 340 of the main circuit board.

[00226] The handle assembly 3 has a lid connecting portion 301, and the lid 70 has mounting holes 724 and a handle hook connecting part 717 for connecting the lid connecting part 301. Accordingly, the handle assembly 3 can be stably connected to the cover 70, and in this method, the handle terminal 90 can be accurately connected to the main body terminal 80. That is, the cover connecting portion 301, the mounting holes 724, and the handle hook connecting portion 717 direct the handle terminal 90 and the main body terminal 80, which are connected to each other, so that the assembly error of the handle terminal 90 and the main body terminal 80 is reduced.

[00227] Since the handle assembly 3 has a housing connecting portion 304, and the second housing 2 of the main body 2 has the first handle connecting parts 139a and 139b, the handle assembly 3 can be stably connected to the second housing 12, and in this method, the handle terminal 90 can be precisely connected to terminal 80 of the main body. That is, the housing connecting portion 304 and the first handle connecting parts 139a and 139b also direct the handle terminal 90 and the main body terminal 80, which are connected to each other, thus, the assembly error of the handle terminal 90 and the main body terminal 80 is reduced.

[00228] Furthermore, as described above, connecting ribs 716a for connecting the main body terminal 80 and a terminal support 716c for supporting the bottom of the main body terminal 80 are formed on the cover 70. Accordingly, the main body terminal 80 is not pressed down when the handle terminal 90 is connected with the main body terminal 80, thus, the assembly error of the handle terminal 90 and the main body terminal 80 is reduced.

[00229] A third connecting structure of the present invention is a connecting structure between wires of a main body electrically connected to a terminal 80 of the main body, a suction motor 20 in the main body 2 and a first terminal 139. This connecting structure is an electrically connected structure located in the main body 2 and carried out by the wires of the main body. The power supplied to the terminal 80 of the main body, ultimately, can be supplied to the suction motor 20 and the first terminal 139 due to the electrically connected design.

[00230] According to the connecting structures of the present invention, air channels are formed only in the main body 2 and are not formed in the handle assembly 3.

[00231] Accordingly, there is no need for a structure for sealing the boundary between the handle unit 3 and the main body 2 when the handle unit 3 is connected to the main body 2. Therefore, the structure for connecting the handle unit 3 to the main body 2 is simple and the connection is easy .

[00232] In the present invention, the suction motor 20 and the first terminal 139 are powered by the battery 40, so they can be called components for receiving power.
