Description

Technical Field

[0001] The present disclosure relates to a cleaner, and more particularly, to a portable stick vacuum cleaner, which can be used as a stick type by combining an extension tube and a brush head, or can be used as a handheld type by separating accessories. Background Art

[0002] Handheld, stick and portable stick vacuum cleaners are usually smaller than horizontal and upright vacuum cleaners, so they are light and easy to hold. In addition, these vacuum cleaners are equipped with rechargeable batteries for self-powering, and these vacuum cleaners are usually cordless.

[0003] In the case of such a cordless vacuum cleaner, it can clean window frames, bookcases, sofas, etc., as well as bottom surfaces (eg, floors) more easily than a vacuum cleaner using a cord.

[0004] In this case, the position and orientation of the user's hands, wrists, and arms using the vacuum cleaner may vary depending on the place and location of vacuuming.

[0005] In other words, since the handle is fixed to the main body, it is usually necessary to twist the wrist or arm to perform cleaning in the direction desired by the user. Therefore, during cleaning, a large load is applied to the wrist or arm, which makes the user easily tired. Summary of the invention

[0006] To solve the above problems, an object of the present disclosure is to provide a portable stick vacuum cleaner capable of selectively adjusting the angle of a handle so that a user can clean in a comfortable posture without twisting the wrist or arm.

[0086] Best Mode for Carrying Out the Invention

[0087] In order to fully understand the structure and effect of the present disclosure, the preferred embodiments of the present disclosure will be described with reference to the accompanying drawings. However, the present disclosure is not limited to the following embodiments, but can be implemented in different forms and various modifications can be made. However, it should be understood that the description of the present embodiment is provided to make the present disclosure complete and to fully convey the scope of the present disclosure to those skilled in the art. In the accompanying drawings, components are enlarged for ease of explanation, and the proportions of components may be exaggerated or reduced.

[0088] The terms "first", "second", etc. may be used to describe various components, and the components should not be limited by the terms. The terms may be used only for the purpose of distinguishing one component from another component. For example, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component without departing from the scope of the present disclosure.

[0089] Unless otherwise defined, terms used in the embodiments of the present disclosure may be construed as being well known to those skilled in the art.

[0090] Hereinafter, the structure of a portable stick vacuum cleaner according to an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

[0091] Figure 1 is a perspective view showing a portable stick vacuum cleaner according to an embodiment of the present disclosure, and

[0092] Figure 2 is a diagram illustrating a state in which a first portion is rotated relative to a second portion in a portable stick vacuum cleaner according to an embodiment of the present disclosure.

[0093] Reference Figure 1 , a portable stick vacuum cleaner 10 according to an embodiment of the present disclosure may include: a first portion 100 in which a dust collecting member 110 is disposed; and a second portion 200 in which a handle 210 is formed.

[0094] Reference Figure 2 , the first part 100 and the second part 200 are rotatably connected to each other through the third part 300. In this case, the first part 100 can rotate relative to the second part 200 around the rotation axis 360 of the third part 300 at a predetermined angle θ. Figure 2 , the angle θ at which the first part 100 is rotatable relative to the second part 200 is shown as approximately an acute angle. However, the present disclosure is not limited thereto. The portable stick vacuum cleaner 10 may be manufactured such that the angle θ at which the first part 100 is rotatable relative to the second part 200 is an obtuse angle.

[0095] On the other hand, the third part 300 may be provided with a mode setting member 410 capable of setting the first part 100 and the second part 200 to a rotation mode in which they are rotatable relative to each other and a fixed mode in which they are fixed relative to each other.

[0096] In this embodiment, the mode setting member 410 exposed to the outside of the third part 300 can be operated to fix the first part 100 and the second part 200 to each other or to keep them in a rotatable state relative to each other. In addition, in this embodiment, when the mode setting member 410 is set to the rotation mode, the first part 100 and the second part 200 are arranged at a desired angle relative to each other. Thereafter, when the mode setting member 410 is set to the fixed mode, the first part 100 and the second part 200 can be maintained at the above arranged angle.

[0097] The mode setting member 410 is a component constituting the locking portion 400 (see Figure 5 ). The structure and operation of the locking portion 400 will be described later.

[0098] In the following, reference will be made to Figure 3 and Figure 4 The third portion 300 configured to rotatably connect the first portion 100 and the second portion 200 relative to each other is described.

[0099] Figure 3 and Figure 4 is an exploded perspective view showing a portable stick vacuum cleaner according to an embodiment of the present disclosure, the portable stick vacuum cleaner being exploded into a first portion and a second portion while having a flexible tube communicating the first portion and the second portion.

[0100] Reference Figure 3 and Figure 4 The third part 300 connecting the first part 100 and the second part 200 may include: a pair of first support parts 320; a pair of second support parts 340 corresponding to the pair of first support parts 320; and a pair of rotating shafts 360 connecting the pair of first support parts 320 and the pair of second support parts 340.

[0101] A pair of first support parts 320 are formed to protrude from both sides of the rear end of the first part 100 in the longitudinal direction of the first part 100. The pair of first support parts 320 are provided with through holes 321 formed on the same axis. Rotating shafts 360 are coupled to the through holes 321, respectively.

[0102] The pair of second support parts 340 are formed to protrude from both sides of the front end of the second part 200 along the longitudinal direction of the second part 200. The width of the pair of second support parts 340 is formed to be smaller than the width of the pair of first support parts 320, and the pair of second support parts 340 are positioned inside the pair of first support parts 320. The pair of second support parts 340 are provided with through holes 341 formed on the same axis and into which the rotating shaft 360 is inserted.

[0103] A pair of rotating shafts 360 are coupled to the through-holes 321 of the first support portion 320 and the through-holes 341 of the second support portion 340 , respectively, so that the first support portion 320 and the second support portion 340 facing each other are rotatably connected.

[0104] Through the third part 300 configured as above, a first axis A1 (see Figure 2 ) and a second axis A2 perpendicular to the rotation axis 360 and along the longitudinal direction of the second portion 200 (see Figure 2 ) can be rotated relative to each other to form a specific angle.

[0105] Therefore, when cleaning is performed using the portable stick vacuum cleaner 10 according to the present embodiment, since the first part 100 can be rotated at a specific angle around the rotation axis 360 relative to the second part 200, the operation of bending or twisting the wrist holding the handle 210 of the second part 200 can be minimized, thereby significantly reducing the load applied to the wrist.

[0106] In the following, reference will be made to Figures 5 to 9 The structure of the locking portion 400 capable of setting the first portion 100 and the second portion 200 to the fixed mode or the rotation mode by locking or unlocking the third portion 300 is described.

[0107] Figure 5is an exploded perspective view showing a locking portion configured to set the first portion and the second portion to a rotation mode or a fixed mode. Figure 6 2 is a diagram showing a locking portion in which a first portion and a second portion are set to a fixed mode in which the first portion and the second portion are not rotatable relative to each other. Figure 7 is shown along Figure 6 A cross-sectional view of the locking portion taken along line AA shown in FIG. Figure 8 is a diagram showing the locking portion in which the first portion and the second portion are set to a rotation mode in which they are rotatable with respect to each other. Fig. 9 is along Figure 8 BB is a cross-sectional view of the locking portion taken along the line shown in FIG.

[0108] Reference Figure 5 , the locking portion 400 may be disposed in the third portion 300. In detail, the mode setting member 410 of the locking portion 400 may be disposed outside the third portion 300, and the remaining components constituting the locking portion 400 may be disposed inside the third portion 300 (between the first supporting portion 320 and the second supporting portion 340).

[0109] The locking portion 410 may include a mode setting member 410 , an elastic member 430 , a latch 450 , and a slider 470 .

[0110] The mode setting member 410 is slidably disposed in the groove 329 (see Figure 3 ), a groove 329 is formed on the outer surface of the first support portion 320 of the third part 300. The length of the groove 329 is formed to be longer than the length of the mode setting member 410. In addition, the groove 329 is formed along the circumferential direction of the first support portion 320. Therefore, the mode setting member 410 can move to a first position corresponding to the fixed mode and a second position corresponding to the rotation mode in the groove 329.

[0111] For user's convenience in operation, the mode setting member 410 may be integrally provided with an anti-slip protrusion 411 on its outer surface.

[0112] The mode setting member 410 may be fastened to the slider 470 by a screw 480. In this case, the mode setting member 410 is provided in an inner surface thereof with a fastening hole 413 to which the screw 480 is fastened.

[0113] The elastic member 430 elastically presses the latch 450 toward the slider 470. The elastic member 430 may be a coil spring, and one end of the elastic member 430 is inserted into the fixing groove 324 formed in the inner surface of the first support portion 320, and the other end is inserted into the fixing protrusion 451 formed on the surface of the latch 450 (see Figure 6 ).

[0114] The latch 450 is slidably disposed in the retracted space 327 between the guide ribs 325 and 326 formed on the inner surface of the first support portion 320 .

[0115] Since the latch 450 is elastically pressed toward the slider 470 by the elastic member 430 , the latch 450 may slide toward the first support portion 320 or the second support portion 340 in cooperation with the movement of the slider 470 .

[0116] The latch 450 has a contact surface 453 formed on a surface facing the slide member 470. The contact surface 453 may contact a first inclined surface 473 (see FIG. 44 ) of the slide member 470 described later. Figure 6 ) and a second inclined surface 475 (see Figure 6 )Slide on contact.

[0117] When the latch 450 is inserted into the retracted space 327 of the first support portion 320, the first part 100 and the second part 200 may be rotated relative to each other. Therefore, the first part 100 and the second part 200 may be set to a rotation mode.

[0118] On the other hand, when the latch 450 is completely released from the retracted space 327 and inserted into any one of the plurality of fixing grooves 345 formed in the second support portion 340 (eg, Figure 6 ), the first part 100 and the second part 200 are not rotatable relative to each other. Therefore, the first part 100 and the second part 200 can be set to a fixed mode.

[0119] Reference Figure 5 The slider 470 is provided with a through hole 471 through which the screw 480 is fastened. The slider 470 is fixed to the mode setting member 410 at a predetermined interval by the screw 480. In this case, an elastic member 430 and a latch 450 are provided between the mode setting member 410 and the slider 470.

[0120] The first support portion 320 is provided with a guide hole 323 so that the screw 480 fastening the mode setting member 410 and the sliding member 470 can move through the guide hole 323. Therefore, when the mode setting member 410 moves to the first position for setting the fixed mode (see Figure 6 and Figure 7 ) or to a second position for setting the rotation mode (see Figure 8 and Fig. 9 ), the sliding member 470 also moves to the first position or the second position together with the mode setting member 410.

[0121] Reference Figure 6 and Figure 7The slider 470 is formed with a first inclined surface 473 and a second inclined surface 475 which are inclined in the same direction on a side surface facing the latch 450. The first inclined surface 473 is located closer to one surface 340a of the second support portion 340 than the second inclined surface 475.

[0122] When the mode setting member 410 moves to the first position (fixed mode), the slide 470 slides along the one surface 340a of the second support portion 340 so that the first inclined surface 473 reaches a position corresponding to the contact surface 453 of the latch 450. In this case, the latch 450 is completely separated from the retracting space 327 (see Figure 5 ), and then, the latch 450 is inserted into any one of the plurality of fixing grooves 345. Therefore, the first support portion 320 and the second support portion 340 are locked to each other, and the first part 100 and the second part 200 cannot rotate around the rotation axis 360.

[0123] Reference Figure 8 and Fig. 9 , the mode setting member 410 moves to the second position (rotation mode), the slider 470 slides along the one surface 340a of the second support portion 340 so that the second inclined surface 475 reaches a position corresponding to the contact surface 453 of the latch 450. In this case, the latch 450 is inserted into the retracted space 327 (see Figure 5 As a result, the first support portion 320 and the second support portion 340 are released from the locked state, so that the first part 100 and the second part 200 can rotate relative to each other.

[0124] When the first part 100 and the second part 200 are rotated to a certain angle around the rotation axis 360 in this state and the mode setting member 410 is moved to the first position, the latch 450 is inserted into any one of the plurality of fixing grooves 345 and the first support portion 320 and the second support portion 340 are locked to each other. Therefore, the first part 100 and the second part 200 cannot rotate around the rotation axis 360.

[0125] However, cleaning can be performed even when the mode setting member 410 moves to the second position. In this case, the first part 100 is maintained in a state where the first part 100 is continuously rotated at an arbitrary angle about the rotation axis 360 relative to the second part 200 .

[0126] In the following, we will refer again to Figure 3 and Figure 4 A structure is described in which the first portion 100 and the second portion 200 are connected to each other by the flexible tube 500 so as to be able to communicate therewith.

[0127] The flexible tube 500 is formed of a flexible material so that it can be easily bent. The flexible tube 500 has one end 510 connected to the rear end of the first part 100 and the other end 530 connected to the front end of the second part 200. Therefore, the first part 100 and the second part 200 are connected to each other through the flexible tube 500 so as to be able to communicate with each other.

[0128] With the suction flow path (see Fig.10 The flexible tube 500 corresponding to the portion between the first part 100 and the second part 200 of the embodiment of the present invention can be naturally bent and maintain the suction flow path when the first part 100 and the second part 200 are rotated relative to each other around the rotation axis 360.

[0129] In this case, in order to prevent air leakage at the connection portion between one end 510 of the flexible tube 500 and the first part 100 and the connection portion between the other end 530 of the flexible tube 500 and the second part 200, the flexible tube 500 needs to have a structure that firmly connects the flexible tube 500 to the first part 100 and the second part 200.

[0130] To this end, the flexible tube 500 may be formed with a spiral protrusion substantially on its outer circumferential surface. The spiral protrusion may be formed on the entire outer circumferential surface of the flexible tube 500, or may be formed only on one end and the other end of the flexible tube 500. The first portion 100 may be provided with a first coupling member 130 (see Figure 3 ), one end 510 of the flexible tube 500 is screwed to the first coupling member 130, and the second part 200 may be provided with a second coupling member 230 on its front end (see Figure 4 ), the other end 530 of the flexible tube 500 is screwed to the second coupling member 230. Each of the first coupling member 130 and the second coupling member 230 is provided with a threaded portion on an inner circumferential surface thereof.

[0131] One end 510 of the flexible tube 500 is screwed to the first coupling member 130, and the other end 530 of the flexible tube 500 is screwed to the second coupling member 230. Therefore, even when the first part 100 and the second part 200 are repeatedly rotated around the rotation axis 360, the one end 510 and the other end 530 of the flexible tube 500 are not separated from the first coupling member 130 and the second coupling member 230, but remain firmly connected to the first coupling member 130 and the second coupling member 230 (see FIG. Fig.10 ).

[0132] On the other hand, when the first part 100 and the second part 200 rotate relative to each other, the flexible tube 500 bends. At this time, when the inside of the bent portion of the flexible tube 500 is too narrow, the suction efficiency may be reduced. Therefore, in order to prevent the suction efficiency from being reduced, a shape retaining member (not shown) may be coupled to the inside of the flexible tube 500. The shape retaining member may be formed in a spiral coil spring shape coupled along a spiral groove formed in the inner surface of the flexible tube 500. Here, the spiral groove corresponds to the inner side of the spiral protrusion formed on the outer circumferential surface of the flexible tube 500.

[0133] In addition, the flexible tube 500 may not be provided with a shape maintaining member. In this case, the flexible tube 500 may be made of a material capable of maintaining a predetermined strength, or may be formed in a bellows shape that is easily expanded and contracted and bent.

[0134] In the fixed mode, the cyclone S1, the flexible pipe 500 and the suction motor 250 may be arranged in one line. In this case, the central axis X1 of the cyclone S1 (see Fig.10 ) and the central axis X2 of the suction motor 250 (see Fig.10 ) may be arranged parallel to or coaxially with each other. In addition, in the rotation mode, the central axis X1 of the cyclone S1 and the central axis X2 of the suction motor 250 may be arranged at an obtuse angle.

[0135] In the following, reference will be made to Figures 10 to 14 The structures of the first portion 100 and the second portion 200 of the portable stick vacuum cleaner 10 will be described in detail.

[0136] Reference Fig.10 and Fig.11a The first part 100 is provided with a suction hole 103 at one end of its front end 101, and air containing dust is introduced through the suction hole 103. Fig.15 As shown in , when the extension tube 30 is used for cleaning, one end of the extension tube 30 may be inserted into the suction hole 103 and mounted to the internal channel 102 of the front end 101. The suction hole 103 is provided at one end of the internal channel 102, and the discharge hole 106 is provided at the other end of the internal channel 102. A locking button 105 for locking or unlocking one end of the extension tube 30 may be provided on the outer surface of the front end 101.

[0137] Although not shown, the diameter of the front end 101 of the first part 100 may be formed to be smaller than the diameter of one end of the extension tube 30, and the front end 101 of the first part 100 may be detachably inserted into one end of the extension tube 30. In this case, the locking button 105 may be provided at one end of the extension tube 30.

[0138] The first part 100 is provided with an installation space 107, in which the dust collecting member 110 and the filter member 120 are detachably installed. The installation space 107 is in fluid communication with the internal passage 102 of the front end 101 through a discharge hole 106 formed in one side surface thereof. In addition, the installation space 107 is provided with a grid filter 116 for filtering dust on the opposite side of the discharge hole 106.

[0139] Reference Fig.12 The interior of the dust collecting member 110 is partitioned into a cyclone S1 and a dust collecting chamber S2 by a partition wall 111 .

[0140] The cyclone S1 may be formed in a cylindrical shape to form a vortex with the vortex guide member 112. In addition, the cyclone S1 is fluidly connected to an inflow hole 114 formed in one side of the dust collecting member 110. The inflow hole 114 is arranged to correspond to the discharge hole 106 so that the internal channel 102 of the front end 101 is fluidly connected to the cyclone S1.

[0141] A vortex induction member 112 for vortexing the air introduced into the cyclone S1 through the inflow hole 114 is provided in the cyclone S1. The vortex induction member 112 includes a cylinder 113 and a spiral blade 115 formed in a spiral direction along the outer peripheral surface of the cylinder 113. The spiral blade 115 forms a spiral passage with the inner wall of the cyclone S1.

[0142] The dust collecting chamber S2 is in fluid communication with the cyclone S1 through a passage, through which dust separated from air by centrifugal force is discharged from the cyclone S1.

[0143] Reference Fig.10 , the filter member 120 may include: a grille filter 116, which is arranged to be partially inserted into the cyclone S1; and a filter chamber S3, which is arranged behind the grille filter 116 and in which an additional filter 117 is arranged. An annular seal 118 coupled to the first coupling member 130 is provided on one side surface of the filter chamber S3. In this case, the first coupling member 130 may be rotatably coupled to the seal 118, wherein the first coupling member 130 and the seal 118 are in close contact with each other to maintain air tightness. The seal 118 maintains air tightness between the filter chamber S3 and the first coupling member 130. The seal 118 is fluidly connected to a through hole 119 formed in the rear wall of the filter member 120, so that air can move from the filter chamber S3 to the flexible tube 500.

[0144] Reference Fig.11a , the filter member 120 can be detachably mounted to the mounting space 107 of the first portion 100 together with the dust collecting member 110. Fig.11bAs shown in FIG. 1 , the filter member 120 separated from the installation space 107 may be separated from the dust collecting member 110 .

[0145] Reference Fig.13 , the suction motor 250 is disposed inside the second part 200. The inlet of the suction motor 250 is disposed to communicate with the other end 530 of the flexible tube 500. The suction motor 250 discharges the air introduced into the inlet of the suction motor 250 through the impeller 251 to the rear of the second part 200.

[0146] Since the through hole 119 and one end 510 of the flexible tube 500 are connected to each other at the rear end of the first part 100, and the other end 530 of the flexible tube 500 is connected to the inlet of the suction motor 250 at the front end of the second part 200, the air filtered in the first part 100 is sucked into the second part 200 through the flexible tube 500 and then discharged to the outside through the exhaust chamber S4.

[0147] Reference Fig.14 , the exhaust chamber S4 is formed at the rear of the second part 200. A through hole 280 is formed in one side surface of the exhaust chamber S4, so that the air exhausted from the suction motor 250 flows into the exhaust chamber S4. In addition, the exhaust chamber S4 may be provided with an exhaust filter 292 to filter fine dust introduced into the exhaust chamber S4. The exhaust filter 292 may be a HEPA filter capable of filtering fine dust or ultrafine dust.

[0148] The exhaust filter 292 may be formed in a substantially annular shape, and a blocking cover 293 may be coupled to a rear surface of the exhaust filter 292. The blocking cover 293 blocks the rear surface of the exhaust filter 292 and guides air to be discharged through a side surface of the exhaust filter 292.

[0149] The exhaust cover 290 is provided at the rear of the second part 200 to surround the exhaust filter 292. A plurality of ribs 291 are arranged on the rear surface of the exhaust cover 290 in the circumferential direction. Each of the ribs 291 may be inclined at a predetermined angle so as to form a ventilation gap between two adjacent ribs. Therefore, the air discharged to the outside of the second part 200 through the exhaust cover 290 is dispersed in the circumferential direction while being discharged.

[0150] On the other hand, the second part 200 may be provided with a handle 210 extending from a portion where the suction motor 250 is provided. In addition, the second part 200 may be provided at the front of the handle 210 with a battery mounting groove 213 in which a rechargeable battery 220 is mounted.

[0151] Hereinafter, the operation of the portable stick vacuum cleaner according to an embodiment of the present disclosure will be described.

[0152] Fig.15is a diagram illustrating a situation in which cleaning is performed using a portable stick vacuum cleaner to which an extension tube to which a suction nozzle is connected is coupled according to an embodiment of the present disclosure.

[0153] Reference Fig.15 The user can connect the extension tube 30 to the front end 101 of the portable stick vacuum cleaner 10, and then repeatedly move the portable stick vacuum cleaner 10 forward and backward to clean the floor while holding the handle 210 with the hand 60. The suction nozzle 40 can be hinged to the lower end of the extension tube 30 by the rotating shaft 50.

[0154] When cleaning is performed while the portable stick vacuum cleaner 10 repeatedly moves forward and backward, the first part 100 rotates clockwise and counterclockwise about the rotation axis 360 relative to the second part 200. At this time, the angle between the first axis A1 and the second axis A2 may continuously change between a first angle β1 and a second angle β2.

[0155] However, when the portable stick vacuum cleaner 10 is repeatedly moved forward and backward for cleaning, the angle α between the third axis A3 along the longitudinal direction of the handle 210 and the fourth axis A4 extending from the user's hand 60 to the lower arm may remain constant or may change by a slight angle.

[0156] Since the angle between the third axis A3 and the fourth axis A4 remains substantially constant, the user can smoothly perform cleaning while holding the handle 210 without bending or twisting the wrist during cleaning.

[0157] At this time, if Fig.15 As shown in FIG. 1 , the angle γ2 between the first axis A1 and the third axis A3 can also be as shown in FIG. Figure 2 In other words, the angle γ2 in the rotating mode is greater than the angle γ1 in the fixed mode. In addition, the third axis A3 is aligned with the central axis X1 of the cyclone S1 (see Fig.10 ) can also be changed, and the angle in the rotating mode is greater than that in the fixed mode.

[0158] As described above, in the portable stick vacuum cleaner 10 according to the embodiment of the present disclosure, since the second part 200 provided with the handle 210 is rotatably connected to the first part 100, the user does not need to make a motion of bending or twisting the wrist holding the handle 210 during cleaning. Therefore, the load applied to the wrist during cleaning is greatly reduced, so that cleaning can be performed more comfortably.

[0159] On the other hand, the portable stick vacuum cleaner 10 according to an embodiment of the present disclosure may be provided with a dust collecting member 600 instead of the above-mentioned dust collecting member 110, and the dust collecting member 600 has a structure capable of effectively discharging thin and flexible dirt (such as human hair or pet hair) from the dust collecting member. Figures 16 to 26 The dust collecting member 600 provided in the portable stick vacuum cleaner 10 according to an embodiment of the present disclosure is described in detail.

[0160] Reference Fig.16 The dust collecting member 600 may include: a container 610 configured to collect dust by separating dust sucked together with the air from the air by centrifugal force; and a cover 630 configured to open and close the rear side of the container 610 .

[0161] The front surface of the container 610 is provided with an air inlet 618, and the air containing dust is discharged from the exhaust hole 106 (see FIG. Fig.10 ) is sucked in. The first sealing member 618a is coupled along the inner circumference of the air inlet hole 618. Therefore, air is prevented from leaking between the discharge hole 106 of the first part 100 and the air inlet hole 618. The first sealing member 618a is formed with a hole 618b, and the discharge hole 106 of the first part 100 and the air inlet hole 618 are connected to each other through the hole 618b.

[0162] A handle 675 of a grille filter member 670 (to be described later) is provided in a state of being exposed around the air inlet hole 618 of the container 610. Therefore, when the grille filter member 670 is to be operated, the user can easily access the handle 675. The grille filter member 670 is provided to be linearly movable inside the container 610 so as to easily separate the hair entangled on the outside of the grille portion 671. The construction and operation of the grille filter member 670 will be described later.

[0163] Reference Fig.17 The cover 630 is detachably coupled to the rear side of the open container 610. The container 610 and the cover 630 are mounted to the mounting space 107 (see FIG. 1 ) of the first portion 100 of the portable stick vacuum cleaner 10. Fig.11a ) are combined with each other at the same time. In this case, the sealing member 632 is combined along the outer edge of the side surface of the cover 630 combined with the container 610. In a state where the cover 630 is combined to the rear side of the container 610, the sealing member 632 prevents air from leaking from between the container 610 and the cover 630, thereby preventing pressure loss. On the other hand, when the dust collected in the container 610 is discharged, the cover 630 is detached from the container 610 to open the rear side of the container 610.

[0164] The cyclone 611 is disposed inside the container 610 , and a dust collecting chamber 610 a for collecting dust discharged from the cyclone 611 is disposed outside the cyclone 611 .

[0165] A plurality of dust discharge portions 611a are formed by cutting off the upper end of the cyclone 611, so that the dust centrifugally separated inside the cyclone 611 can be discharged to the dust collecting chamber 610a (see Fig.19 ). In other cases, the dust discharge part 611a may not be formed in a plurality but may be formed in a single one. The dust discharge part 611a is a passage for connecting the inside of the cyclone 611 and the dust collecting chamber 610a.

[0166] Reference Fig.18 , the grid filter member 670 is arranged inside the cyclone 611 to be able to move forward and backward in the axial direction of the cyclone 611. A cylindrical guide pipe 619 is formed at the inner center of the cyclone 611 in the axial direction, and a spiral guide 613 is formed between the outer peripheral surface of the cylindrical guide pipe 619 and the inner peripheral surface of the cyclone 611 in the spiral direction.

[0167] The spiral guide 613 guides the dust and air introduced into the cyclone 611 through the air inlet 618 in a spiral direction. The dust and air pass through the inlet hole 615 (which is the inlet of the spiral guide 613), and then move toward the dust discharge part 611a along the spiral guide 613. At this time, the dust is introduced into the dust collecting chamber 610a through the dust discharge part 611a by centrifugal force.

[0168] Reference Figures 19 to 21 , the guide pipe 619 is provided with a plurality of catching protrusions 616 protruding from a distal end 619a of the guide pipe 619, and the plurality of catching protrusions 616 are separated from each other by a predetermined interval.

[0169] The plurality of catching protrusions 616 are formed in such a shape that, when the grille filter member 670 is retracted, hair wound on the outer surface of the grille portion 671 of the grille filter member 670 can be easily separated from the outer surface of the grille filter member 670. In other words, the plurality of catching protrusions 616 are inclined at a predetermined angle toward the center of the guide tube 619 so that the plurality of catching protrusions 616 are positioned further inward from the outer surface of the grille portion 671 of the grille filter member 670 from the lower end 616b to the distal end 616a of the catching protrusions 616. The grille portion 671 of the grille filter member 670 is formed with a plurality of grooves 671a along the longitudinal direction of the grille filter member 670 to correspond to the shape of the plurality of catching protrusions 616.

[0170] In addition, the plurality of catching protrusions 616 may have a shape that gradually widens from the tip 616a to the lower end 616b, for example, a trapezoid or a triangle.

[0171] When the grill filter member 670 is moved in the rearward direction (see Fig.26 When the hair 700 (see arrow F in FIG. 1 ) is wound on the outer surface of the grid portion 671 of the grid filter member 670, Fig. 27 ) retracts together with the grille portion 671 and separates from the grille portion 671 when captured by the outer surfaces of the plurality of capturing protrusions 616.

[0172] Reference Fig.18 , when the grille filter member 670 is retracted, a receiving space 619b for receiving the grille portion 671 is provided in the guide pipe 619. In addition, the guide pipe 619 is formed with a through hole 619c through which the connecting rod 673 of the grille filter member 670 passes. With this structure, when the grille filter member 670 moves forward and backward, the guide pipe 619 can guide the grille filter member 670 to move in a straight line direction.

[0173] Reference Fig. 22 , an inflow hole 631 is formed in the front surface of the cover 630, and the air having passed through the grille portion 671 flows into the inside of the cover 630 through the inflow hole 631. An annular gasket 635 for maintaining airtightness between the inflow hole 631 and the grille portion 671 is coupled to the inflow hole 631. The gasket 635 prevents dust and air from flowing directly into the cover 630 through the inflow hole 631 without passing through the grille portion 671.

[0174] When the end 671c of the grille 671 is inserted, the gasket 635 is engaged with the grille 671 under pressure. In this case, the gasket 635 is provided with a plurality of sealing protrusions 635a corresponding to the plurality of grooves 671a along the inner surface to prevent air from leaking through the plurality of grooves 671a of the grille 671.

[0175] Reference Fig.18 A filter 637 for filtering dust (fine dust) contained in the air introduced into the cover 630 through the inflow hole 631 is provided inside the cover 630 .

[0176] Reference Fig.18 , a discharge hole 633 is formed in the rear surface of the cover 630 to discharge the air filtered of fine dust through the filter 637 to the outside of the cover 630. The discharge hole 633 of the cover 630 may be connected to the flexible tube 500 (see Figure 4 ) to communicate with the flexible tube 500. In this case, the discharge hole 633 and the end 510 of the flexible tube 500 can be connected by an intermediary member (such as the first coupling member 130 (see Figure 3 )) are connected to each other.

[0177] The dust collecting member 600 may be detachably mounted in the mounting space 107 of the first part 100. In this case, the discharge hole 106 of the first part 100 is connected to the air inlet 618 of the dust collecting member 600, and the discharge hole 633 of the dust collecting member 600 is connected to the flexible tube 500, thereby forming a flow path. The flexible tube 500 may be disposed inside the third part.

[0178] In the fixed mode, the cyclone 611, the flexible tube 500 (see Fig.10 ) and suction motor 250 (see Fig.10 ) can be arranged on a line. In this case, the central axis (not shown) of the cyclone 611 and the central axis X2 (see Fig.10 ) can be arranged parallel to or coaxially with each other. In addition, in the rotation mode, the central axis of the cyclone 611 and the central axis X2 of the suction motor 250 can be arranged at an obtuse angle.

[0179] Reference Fig.23 The grill filter member 670 may include a grill portion 671 for filtering dust, a handle 675 for moving the grill portion 671 , and a connecting rod 673 for connecting the grill portion 671 and the handle 675 .

[0180] The grille portion 671 may be formed in a cylindrical shape having a plurality of holes having a size larger than that of fine dust to filter dust, hair, etc. The grille portion 671 has an open front surface and a closed rear surface connected to one end of the connection rod 673.

[0181] The front surface of the handle 675 is connected to the other end of the connecting rod 673, and the rear surface of the handle 675 is exposed to the rear side of the container 610 (see Fig.16 ). Accommodating groove 676 (see Fig. 22 ) may be formed on the rear surface of the handle 675 so that it can be hooked and pulled with fingers or the like.

[0182] An engagement groove 675a ​​and a locking claw 675c for holding a position (hereinafter referred to as a filtering position) at which the grille portion 671 of the grille filter member 670 is pressed against and coupled to the pad 635 are formed on the bottom surface of the handle 675. Fig.24 As shown in FIG. 6 , in the filtering position, the engagement protrusion 621 provided in the container 610 can be engaged with the engagement groove 675a. The engagement protrusion 621 is formed on the bottom surface of the guide member 620 for accommodating the handle 675. Fig.25 As shown in FIG. 6 , the engagement protrusion 621 may be formed on a protrusion portion 621 a having a cantilever shape to facilitate snapping of the engagement groove 675 a .

[0183] The locking claw 675c prevents the grill filter member 670 from returning by itself in the filtering position when the user does not pull the handle 675.

[0184] The guide groove 675b is formed in the bottom surface of the handle 675 and is separated from the engagement groove 675a ​​by the locking claw 675c. The guide groove 675b is formed along the moving direction of the grill filter member 670 so that when the grill filter member 670 is moved along the moving direction, the grill filter member 670 is locked. Fig.26 When the handle 675 is pulled in the direction of arrow F shown in the figure to release the snap connection between the engagement groove 675a ​​and the engagement protrusion 621, the bottom surface of the handle 675 does not interfere with the engagement protrusion 621. The width and depth of the guide groove 675b may be greater than the width and depth of the engagement protrusion 621, respectively.

[0185] The grill filter member 670 may have a length such that when the engagement groove 675a ​​of the handle 675 is engaged with the engagement protrusion 621, the end 671a of the grill portion 671 presses against the pad 635 and engages with the pad 635. The length of the grill filter member 670 may be the length from the front surface of the grill portion 671 to the engagement groove 675a ​​of the handle 675.

[0186] One end of the connecting rod 673 is connected to the rear surface of the grille portion 671, and the other end of the connecting rod 673 is connected to the front surface of the handle 675. The connecting rod 673 is always kept in the through hole 619c (see Fig.18 ) status.

[0187] In the following, reference will be made to Figure 27 to Figure 29 A process of separating the hair entangled on the outer surface of the grid portion 671 from the grid portion 671 and discharging the hair from the container 610 is described.

[0188] Reference Fig. 27 When dust on the surface to be cleaned is sucked by the portable stick vacuum cleaner 10, air containing various dirt (such as dust, hair, etc.) flows into the interior of the container 610 through the air inlet hole 618. Subsequently, the dirt and air pass through the inlet hole 615 (which is the inlet of the spiral guide 613), and then move toward the grille portion 671 along the spiral guide 613.

[0189] The relatively heavy dirt in the dirt is discharged by the centrifugal force through the dust discharge part 611a (see Fig.19 ) is introduced into the dust collecting chamber 610a. At this time, relatively light dirt (for example, hair, fine dust, etc.) in the dirt is sucked into the grille portion 671 together with the air.

[0190] In this case, air and fine dust are sucked into the cover 630 through the inside of the grille portion 671, and the fine dust is filtered by the filter 637 provided inside the cover 630. Most of the thin and long dirt (such as hair) does not pass through the many holes of the grille portion 671, but is entangled on the outer surface of the grille portion 671 by the vortex airflow formed inside the cyclone 611.

[0191] When the surface to be cleaned is cleaned using the above-described portable stick vacuum cleaner 10 and dirt collected in the container 610 is discarded, the dust collecting member 600 is separated from the installation space 107 of the first part 100 (see FIG. 11 ), and then the cover 630 is detached from the container 610 .

[0192] Then, if Fig.28 As shown in FIG. 6 , when the handle 675 of the grid filter member 670 is pulled in the direction of arrow F, the grid portion 671 is retracted and inserted into the accommodation space 619b of the guide tube 619. At this time, the hair 700 wound on the outer surface of the grid portion 671 moves together with the grid portion 671 and is separated from the outer surface of the grid portion 671 by the plurality of capture protrusions 616. At this time, the hair 700 surrounds the outer surface of the plurality of capture protrusions 616, thereby being completely separated from the grid portion 671.

[0193] In this state, if Fig.29 As shown in FIG. 6 , when the container 610 is tilted, the hair 700 inside the cyclone 611 and the dust 701 collected in the dust collecting chamber 610a can be emptied. Fig.29 , reference numeral 800 denotes a trash can.

[0194] Since the size of the grill portion 671 of the grill filter member 670 is larger than the diameter of the accommodation space 619b, the grill filter member 670 is not separated from the container 610 when the snap fit between the engagement protrusion 621 and the engagement groove 675a ​​is released and the grill filter member 670 is retracted.

[0195] As described above, when the grill filter member 670 is retracted, the hair 700 wrapped around the outer surface of the grill portion 671 is mostly separated from the grill portion 671 by the plurality of capture protrusions 616, but some hair may be stuck in the plurality of holes of the grill portion 671, etc. Fig.30 As shown, in order to effectively separate the some hair from the grid portion 671 , the grid filter member 670 may be elastically disposed in the container 610 by coupling the elastic member 690 to the connecting rod 673 .

[0196] In this case, in order to remove the hair stuck in the plurality of holes of the grille portion 671, when the handle of the grille filter member 670 is pulled in the direction of the arrow F and then released, the grille filter member 670 moves forward by the elastic force of the elastic member 690. At this time, when the front surface of the handle 675 collides with the partition wall 623, the vibration caused by the collision is transmitted to the grille portion 671 through the connecting rod 673.

[0197] When the grid portion 671 vibrates, hair stuck in the plurality of holes of the grid portion 671 can be easily separated. In addition, when the grid filter member 670 is repeatedly retracted and then the handle 675 is released, hair adhered to the grid portion 671 can be more effectively separated.

[0198] The portable stick vacuum cleaner 10 according to an embodiment of the present disclosure has a structure in which a first portion 100 including a dust collecting member 110 and a second portion 200 including a suction motor 250 and a handle 210 rotate around a rotation axis 360 of a third portion 300 disposed between the first portion 100 and the second portion 200, and the dust collecting member 110 of the first portion 100 and the suction motor 250 of the second portion 200 are fluidically connected to each other through a flexible tube 500 disposed inside the third portion 300. However, the structure of the portable stick vacuum cleaner according to an embodiment of the present disclosure is not limited thereto.

[0199] In other words, in the portable stick vacuum cleaner according to another embodiment of the present disclosure, the dust collecting member, the suction motor, the rechargeable battery, and the handle may be arranged in the first part, the second part, and the third part in different ways.

[0200] In the following, reference will be made to Figures 31 to 46 The portable stick vacuum cleaner described below is different from the portable stick vacuum cleaner 10 according to the above-described embodiment in that the dust collecting member and the suction motor are not connected using a flexible tube.

[0201] First, refer to Figure 31 to Figure 34 A portable stick vacuum cleaner 1000 is described in accordance with an embodiment of the present disclosure.

[0202] Fig.31 is a diagram illustrating a portable stick vacuum cleaner according to another embodiment of the present disclosure. Fig.32 yes Fig.31 A cross-sectional view of a portable stick vacuum cleaner. Fig.33 is along Fig.32 2 is a cross-sectional view of a portable stick vacuum cleaner taken along line DD shown in FIG. Fig.34 It is shown Fig.31A diagram showing a state in which the handle of a portable stick vacuum cleaner is rotated at a specific angle.

[0203] Reference Figure 31 to Figure 34 , a portable stick vacuum cleaner 1000 according to an embodiment of the present disclosure may include: a first part 1100 provided with a dust collecting member 1110 ; a second part 1200 provided with a handle 1210 ; and a third part 1300 provided with a suction motor 1310 .

[0204] In detail, the first part 1100 is provided with a dust collecting member 1110, a connection pipe 1120 and a rechargeable battery 1130. The dust collecting member 1110, the connection pipe 1120 and the rechargeable battery 1130 may be as shown in FIG. Fig.31 and Fig.32 Arranged side by side as shown in .

[0205] The dust collecting member 1110 may include a cyclone 1111 for separating dust from the incoming air by vortexing the incoming air, and a dust collecting chamber 1112 for collecting the dust separated by the cyclone 1111. The first portion 1100 is provided with a mounting portion 1140 in which the dust collecting member 1110 is disposed. The mounting portion 1140 is provided with an exhaust passage 1141 configured to guide the air exhausted from the dust collecting member 1110 to the suction motor 1310. The dust collecting chamber 1112 may be detachably provided.

[0206] The connecting pipe 1120 is provided at one side of the dust collecting member 1110, and has an inlet 1121 at one end of the connecting pipe 1120 (through which external air is introduced), and has an outlet 1122 at the other end of the connecting pipe 1120 (the outlet 1122 is communicated with the inlet of the dust collecting member 1110). Fig.15 The extension pipe 30 shown in FIG. 1 may be detachably connected to the inlet 1121 of the connection pipe 1120 . Therefore, external air is introduced into the cyclone 1111 of the dust collecting member 1110 through the connection pipe 1120 .

[0207] The rechargeable battery 1130 is provided at one side of the connection pipe 1120. In detail, the rechargeable battery 1130 is provided to face the dust collecting member 1110, and the connection pipe 1120 is interposed between the rechargeable battery 1130 and the dust collecting member 1110. Therefore, the connection pipe 1120 and the rechargeable battery 1130 are integrally fixed to the mounting portion 1140 at one side of the dust collecting member 1110. The rechargeable battery 1130 supplies power to the suction motor 1310.

[0208] In the third part 1300, a suction motor 1310 and a filter 1320 are provided. The third part 1300 is formed integrally with the first part 1100 and includes a motor housing 1330 in which the suction motor 1310 and the filter 1320 are embedded. The motor housing 1330 is provided with an inlet for communicating with the exhaust passage 1141 of the first part 1100, and a plurality of exhaust slots 1331 for exhausting the air that has passed through the suction motor 1310 and the filter 1320 to the outside of the motor housing 1330. A HEPA filter may be used as the filter 1320. Therefore, the air introduced into the inlet of the housing 1330 of the third part 1300 passes through the suction motor 1310 and the filter 1320, and then is exhausted to the outside of the third part 1300 through the exhaust slot 1331.

[0209] A pair of first support parts 1340 for supporting the rotation of the second part 1200 may be provided at both ends of the motor housing 1330 of the third part 1300 .

[0210] The second part 1200 is provided with a handle 1210. The second part 1200 is formed as a rotatable structure relative to the third part 1300. For example, the second part 1200 may include a pair of second support parts 1220 corresponding to a pair of first support parts 1340 of the third part 1300 and a handle 1210 connected to the pair of second support parts 1220. The pair of second support parts 1220 and the handle 1210 are connected to each other by a connecting part 1230. The pair of first support parts 1340 and the pair of second support parts 1220 are rotatably connected to each other by a pair of rotating shafts 1240. At this time, the pair of rotating shafts 1240 may be arranged coaxially with the rotating shaft 1311 of the suction motor 1310 provided in the motor housing 1330 of the third part 1300.

[0211] Therefore, the handle 1210 of the second part 1200 can be rotated relative to the first part 1100 about a pair of rotation axes 1240 by a predetermined angle. For example, the handle 1210 can be made by making the handle 1210 (such as Fig.31 ) is rotated counterclockwise around a pair of rotating shafts 1240 by a predetermined angle, and is substantially in a line with the dust collecting member 1110 (as shown in Fig.34 ).

[0212] In addition, the third part 1300 is provided with a mode setting member 1400, which is configured to set the first part 1100 and the second part 1200 to a rotation mode (wherein the first part 1100 and the second part 1200 can rotate around each other) or a fixed mode (wherein the first part 1100 and the second part 1200 are fixed to each other).

[0213] The first part 1100 and the second part 1200 can be fixed to each other or rotatable relative to each other by operating the mode setting member 1400. In addition, when the mode setting member 1400 is set to the rotation mode, the first part 1100 and the second part 1200 are arranged at a desired angle. Thereafter, when the mode setting member 1400 is set to the fixed mode, the first part 1100 and the second part 1200 can maintain the arranged angle. Since the structure and operation of the mode setting member 1400 are the same or similar to the structure and operation of the mode setting member 410 of the above-mentioned embodiment, a detailed description thereof is omitted.

[0214] In the following, reference will be made to Fig.32 The operation of a portable stick vacuum cleaner according to an embodiment of the present disclosure is described.

[0215] When the suction motor 1310 is operated by power supplied from the rechargeable battery 1130, suction force is generated and external air is sucked into the inlet 1121 of the connection pipe 1120. The sucked external air moves along the connection pipe 1120 and enters the cyclone 1111 of the dust collecting member 1110.

[0216] While the external air passes through the cyclone 1111, dust and dirt contained in the external air are separated from the air and collected in the dust collecting chamber 1112. The cleaned air flows into the suction motor 1310 provided in the motor housing 1330 through the exhaust passage 1141 provided in the mounting portion 1140.

[0217] The air introduced into the suction motor 1310 passes through a filter 1320 disposed below the suction motor 1310 and is then discharged to the outside of the motor housing 1330 through a plurality of discharge grooves 1331 .

[0218] As described above, when cleaning is performed using the portable stick vacuum cleaner 1000 according to the embodiment of the present embodiment, the second part 1200 provided with the handle 1210 can be rotated at a certain angle around the rotation axis 1240 relative to the first part 1100. Therefore, the bending or twisting operation of the wrist holding the handle 1210 of the second part 1200 can be minimized, thereby greatly reducing the load applied to the wrist.

[0219] Then, refer to Figure 35 to Figure 39 A portable stick vacuum cleaner 2000 is described in accordance with an embodiment of the present disclosure.

[0220] Fig.35 is a diagram illustrating a portable stick vacuum cleaner according to another embodiment of the present disclosure.

[0221] Reference Figures 35 to 38 , a portable stick vacuum cleaner 2000 according to an embodiment of the present disclosure may include: a first part 2100 provided with a dust collecting member 2110 and a suction motor 2120 ; a second part 2200 provided with a handle 2210 ; and a third part 2300 provided with a rechargeable battery 2310 .

[0222] In detail, the dust collecting member 2110 and the suction motor 2120 are provided in the first part 2100. The dust collecting member 2110 and the suction motor 2120 may be as follows. Fig.36 As shown in , they are arranged in a straight line.

[0223] The first part 2100 may include a housing 2130 in which the dust collecting member 2110 and the suction motor 2120 are disposed. The suction motor 2120 is disposed in the lower portion of the housing 2130, and the dust collecting member 2110 is disposed in the upper portion of the housing 2130 (ie, above the suction motor 2120).

[0224] The inlet 2131 is provided at one side of the housing 2130, and external air containing dust is sucked in through the inlet 2131. An internal passage 2132 for guiding external air to the inlet 2113 of the dust collecting member 2110 is provided between the inlet 2131 and the dust collecting member 2110. Fig.15 The extension pipe 30 shown in FIG. 21 may be detachably connected to the inlet 2131 of the housing 2130 . Therefore, external air is introduced into the dust collecting member 2110 through the inlet 2131 of the housing 2130 and the internal passage 2132 .

[0225] The dust collecting member 2110 may include a cyclone 2111 for separating dust from incoming air by vortexing the incoming air, and a dust collecting chamber 2112 for collecting dust separated by the cyclone 1111. The dust collecting chamber 2112 may be detachably provided in the housing 2130.

[0226] The discharge port 2114 of the dust collecting member 2110 is in fluid communication with the inlet of the suction motor 2120. A filter 2140 for filtering air is provided at the outlet of the suction motor 2120. A plurality of discharge slots 2141 are provided at the lower portion of the housing 2130, and air having passed through the filter 2140 is discharged through the plurality of discharge slots 2141. A HEPA filter may be used as the filter 2140.

[0227] The battery mounting portion 2320 is disposed at the other side of the housing 2130 , that is, a portion of the housing 2130 opposite to a portion of the housing 2130 where the inlet 2131 is disposed.

[0228] The rechargeable battery 2310 is disposed in the third part 2300. The third part 2300 is integrally formed with the first part 2100, and includes a battery mounting portion 2320 in which the rechargeable battery 2310 is embedded. The battery mounting portion 2320 is formed in a substantially hollow cylindrical shape and is fixed to the housing 2130 by a fixing portion 2330. A cylindrical rechargeable battery 2310 having a plurality of battery cells 2311 arranged in a circle may be disposed in the battery mounting portion 2320.

[0229] A pair of first support portions 2340 for supporting the rotation of the second portion 2200 may be provided at both ends of the battery mounting portion 2320 of the third portion 2300 .

[0230] The handle 2210 is provided in the second part 2200. The second part 2200 is formed to be rotatable relative to the third part 2300. For example, the second part 2200 may include a pair of second support parts 2220 corresponding to the pair of first support parts 2340 of the third part 2300 and a handle 2210 connected to the pair of second support parts 2220. The pair of second support parts 2220 and the handle 2210 are connected to each other through the connecting part 2230. The pair of first support parts 2340 and the pair of second support parts 2220 are rotatably connected through a pair of rotating shafts 2240.

[0231] Therefore, the handle 2210 of the second part 2200 can be rotated relative to the first part 2100 about a pair of rotation axes 2240 to a specific angle. Fig.35 ) is rotated counterclockwise about a pair of rotation axes 2240 by a specific angle so that the handle 2210 can be positioned substantially perpendicular to the housing 2130 (as shown in Fig.38 ).

[0232] In addition, the third part 2300 may be provided with a mode setting member 2400, which is used to set the first part 2100 and the second part 2200 to one of a rotation mode (in which the first part 2100 and the second part 2200 can rotate relative to each other) and a fixed mode (in which the first part 2100 and the second part 2200 are fixed to each other).

[0233] The first part 2100 and the second part 2200 can be kept in a fixed state or a rotatable state relative to each other by operating the mode setting member 2400. In addition, when the mode setting member 2400 is set to the rotation mode, the first part 2100 and the second part 2200 are arranged at a desired angle. Thereafter, when the mode setting member 2400 is set to the fixed mode, the first part 2100 and the second part 2200 can maintain the arranged angle. Since the structure and operation of the mode setting member 2400 are the same or similar to the structure and operation of the mode setting member 410 according to the above-mentioned embodiment, a detailed description thereof is omitted.

[0234] In the following, reference will be made to Fig.36 The operation of a portable stick vacuum cleaner according to an embodiment of the present disclosure is described.

[0235] When the suction motor 2310 is operated by power supplied from the rechargeable battery 1130, suction force is generated, and external air is sucked into the inlet 2131 of the housing 2130. The sucked external air is introduced into the cyclone 2111 of the dust collecting member 2110 through the internal passage 2131 of the housing 2130.

[0236] While the external air passes through the cyclone 2111, dust and dirt contained in the external air are separated from the air and collected in the dust collecting chamber 2112. The cleaned air flows into the suction motor 2120 through the exhaust port 2114 of the dust collecting chamber 2110.

[0237] The air introduced into the suction motor 2120 passes through a filter 2140 disposed below the suction motor 2120 and is then discharged to the outside of the housing 2130 through a plurality of discharge grooves 2141 .

[0238] When cleaning is performed using the portable stick vacuum cleaner 2000 having such a structure according to the present embodiment, the second part 2200 provided with the handle 2210 can be rotated at a certain angle around the rotation axis 2240 relative to the first part 2100. Therefore, the bending or twisting operation of the wrist holding the handle 2210 of the second part 2200 can be minimized, so that the load applied to the wrist can be greatly reduced.

[0239] In the above description, the portable stick vacuum cleaner 2000 having a structure in which the air exhausted from the suction motor 2120 is directly exhausted to the outside through the plurality of exhaust slots 2141 of the housing 2130 has been described. However, as another example, the portable stick vacuum cleaner may be configured so that the exhausted air cools the rechargeable battery 2310 of the third part 2300.

[0240] Fig.39A portable stick vacuum cleaner 2000 having a structure for cooling a rechargeable battery 2310 provided in a third portion 2300 with exhausted air is illustrated.

[0241] Reference Fig.39 , the exhaust duct 2150 is provided at one side of the housing 2130 so that the air outlet 2133 of the lower portion of the housing 2130 communicates with the battery mounting portion 2320. The fixing portion 2330 of the battery mounting portion 2320 is provided with an air passage 2331 communicating with the exhaust duct 2150. Therefore, the exhaust duct 2150 of the housing 2130 and the air passage 2331 of the fixing portion 2330 form an exhaust passage for guiding air exhausted from the suction motor 2120 provided in the housing 2130 to the rechargeable battery 2310.

[0242] In addition, the rechargeable battery 2310 is formed in a cylindrical shape, and a through hole 2312 through which air can pass is provided at the center of the rechargeable battery 2310. In addition, a plurality of exhaust grooves (not shown) through which air can be exhausted are provided at one end of the battery mounting portion 2320. Therefore, the air introduced into the battery mounting portion 2320 through the exhaust passage passes through the through hole 2312 of the rechargeable battery 2310 and is then exhausted to the outside of the battery mounting portion 2320 through the exhaust groove.

[0243] When the rechargeable battery 2310 is cooled by using the air exhausted from the suction motor 2310, the rechargeable battery 2310 can be effectively cooled.

[0244] In addition to the above-mentioned discharge channels, Fig.39 The portable stick vacuum cleaner 2000 shown in FIG. Figures 35 to 38 The portable stick vacuum cleaner 2000 shown in FIG. 1 is the same as the portable stick vacuum cleaner 2000 shown in FIG. 1 , and thus a detailed description thereof is omitted.

[0245] Next, refer to Figures 40 to 44 A portable stick vacuum cleaner 3000 according to an embodiment of the present disclosure is described.

[0246] Fig.40 is a diagram illustrating a portable stick vacuum cleaner according to another embodiment of the present disclosure. Fig.41 yes Fig.40 A cross-sectional view of a portable stick vacuum cleaner. Fig.42 is along Fig.41 A cross-sectional view of a portable stick vacuum cleaner taken along line FF shown in FIG. Fig.43 It is shown Fig.40 A diagram showing a state in which the handle of a portable stick vacuum cleaner is rotated at a specific angle. Fig.44 It is shown Fig.40 sectional view of a modified example of a portable stick vacuum cleaner.

[0247] Reference Figure 40 to Figure 42 , a portable stick vacuum cleaner 3000 according to an embodiment of the present disclosure may include: a first part 3100 provided with a dust collecting member 3110 ; a second part 3200 provided with a handle 3210 and a rechargeable battery 3250 ; and a third part 3300 provided with a suction motor 3310 .

[0248] In detail, the dust collecting member 3110 is disposed in the first part 3100. The first part 3100 may include a mounting portion 3120 in which the dust collecting member 3110 is disposed. An air inlet 3130 is disposed at one side of the dust collecting member 3110, and external air containing dust is sucked through the air inlet 3130. The air inlet 3130 may be formed integrally with the mounting portion 3120. The dust collecting member 3110 may be disposed between the mounting portion 3120 and the air inlet 3130.

[0249] The air intake portion 3130 is provided with an inlet 3131 through which external air is introduced, and an internal passage 3132 through which the introduced external air is guided to the inflow hole 3113 of the dust collecting member 3110. Fig.15 The extension pipe 30 shown in FIG. 31 may be detachably connected to the inlet 3131 of the air intake portion 3130 . Therefore, external air is introduced into the dust collecting member 3110 through the inlet 3131 of the air intake portion 3130 and the internal passage 3132 .

[0250] The dust collecting member 3110 may include a cyclone 3111 for separating dust from incoming air by vortexing the incoming air, and a dust collecting chamber 3112 for collecting dust and dirt separated by the cyclone 3111 .

[0251] The dust collecting member 3110 is arranged in the mounting portion 3120 so that the cyclone 3111 is substantially parallel to the internal passage 3132 of the air inlet portion 3130. Fig.41 As shown in FIG. 3 , the dust collecting member 3110 may be arranged in the mounting portion 3120 such that the direction of the air discharged from the discharge port 3114 of the cyclone 3111 is substantially parallel to the direction of the incoming air sucked into the internal passage 3132. Fig.15 When the extension pipe 30 is disposed at the inlet 3131 of the air intake portion 3130 , the dust collecting member 3110 and the extension pipe 30 are substantially in line.

[0252] Furthermore, the mounting portion 3120 is provided with an exhaust passage 3121 to guide air exhausted from the dust collecting member 3110 to the suction motor.

[0253] The suction motor 3310 is provided in the third part 3300. The third part 3300 is integrated with the first part 3100, and includes a motor housing 3320 in which the suction motor 3310 is embedded. The motor housing 3320 may be provided with: an inlet communicating with the exhaust passage 3121 of the first part 3100; and an exhaust hole for exhausting the air having passed through the suction motor 3310 to the outside of the motor housing 3320. Therefore, the air introduced into the inlet of the motor housing 3320 of the third part 3300 passes through the suction motor 3310 and is then exhausted through the exhaust hole.

[0254] A pair of first support portions 3340 for supporting the rotation of the second portion 3200 may be provided at both ends of the motor housing 3320 of the third portion 3300 .

[0255] The second part 3200 is provided with a handle 3210 and a rechargeable battery 3250. The second part 3200 is formed as a rotatable structure relative to the third part 3300. For example, the second part 3200 may include a pair of second support parts 3220 corresponding to a pair of first support parts 3340 and a handle 3210 connected to the pair of second support parts 3220. The pair of second support parts 3220 and the handle 3210 are connected to each other by a connecting part 3230. The pair of first support parts 3340 and the pair of second support parts 3220 are rotatably connected by a pair of rotating shafts 3240. At this time, the pair of rotating shafts 3240 may be arranged to be coaxial with the rotating shaft of the suction motor 3310 arranged in the motor housing 3320 of the third part 3300.

[0256] Therefore, the handle 3210 of the second part 3200 can be rotated at a specific angle relative to the first part 3100 about the pair of rotation axes 3240. For example, the handle 3210 (eg, Fig.40 ) is rotated counterclockwise around a pair of rotation axes 3240 by a specific angle so that the dust collecting member 3110 and the handle 3210 can form an obtuse angle (as shown in Fig.43 ).

[0257] The handle 3210 may be formed in a hollow shape. In other words, the air passage 3211 may be provided inside the handle 3210. The air passage 3211 inside the handle 3210 forms an exhaust passage through which the air exhausted from the exhaust hole of the motor housing 3320 passes. At this time, the connection portion 3230 provided with the handle 3210 may be provided with a guide flow passage for guiding the air exhausted from the exhaust hole of the motor housing 3320 to the air passage 3211 of the handle 3210.

[0258] The filter housing 3260 is provided at one end of the handle 3210. The filter housing 3260 is provided with a filter 3270 for filtering the air exhausted from the suction motor 3310. A plurality of exhaust grooves 3261 through which the air is exhausted may be provided on the outer peripheral surface of the filter housing 3260. Therefore, the air having passed through the handle 3210 is filtered by the filter 3270 provided in the filter housing 3260, and then exhausted to the outside through the plurality of exhaust grooves 3261. A HEPA filter may be used as the filter 3270.

[0259] The rechargeable battery 3250 is provided at one side of the handle 3210. In detail, the rechargeable battery 3250 is provided in the connection part 3230 located at one side of the handle 3210, and is spaced apart from the handle 3210 by a predetermined distance. At this time, the handle 3210 and the rechargeable battery 3250 are separated from each other so that the user's hand can be inserted. One end of the rechargeable battery 3250 is connected to the filter housing 3260. Since both ends of the rechargeable battery 3250 are supported by the connection part 3230 and the filter housing 3260, the rechargeable battery 3250 is stably fixed to the handle 3210. The rechargeable battery 3250 supplies power to the suction motor 3310.

[0260] In addition, the third part 3300 may be provided with a mode setting member 3400, which is configured to set the first part 3100 and the second part 3200 to one of a rotation mode (in which the first part 3100 and the second part 3200 can rotate relative to each other) and a fixed mode (in which the first part 3100 and the second part 3200 are fixed to each other).

[0261] Therefore, when the mode setting member 3400 is operated, the first part 3100 and the second part 3200 may be fixed or rotatable relative to each other. In addition, when the mode setting member 3400 is set to the rotation mode, the first part 3100 and the second part 3200 are arranged at a desired angle. Thereafter, when the mode setting member 3400 is set to the fixed mode, the first part 3100 and the second part 3200 may maintain the arranged angle. Since the structure and operation of the mode setting member 3400 are the same or similar to the structure and operation of the mode setting member 410 according to the above-mentioned embodiment, a detailed description thereof is omitted.

[0262] In the following, reference will be made to Fig.41 The operation of a portable stick vacuum cleaner according to an embodiment of the present disclosure is described.

[0263] When the suction motor 3310 is operated by power supplied from the rechargeable battery 3250, suction force is generated, and external air is sucked into the inlet 3131 of the air intake portion 3130. The sucked external air moves along the internal passage 3132 and enters the cyclone 3111 of the dust collecting member 3110.

[0264] While the external air passes through the cyclone 3111, dust and dirt contained in the external air are separated from the air and collected in the dust collecting chamber 3112. The cleaned air is introduced into the suction motor 3310 provided in the motor housing 3320 through the exhaust passage 3121 provided in the mounting portion 3120.

[0265] The air that has flowed into the suction motor 3310 is discharged through the discharge hole of the suction motor 3310. The air discharged from the suction motor 3310 is introduced into the filter housing 3260 through the air channel 3211 inside the handle 3210. The air introduced into the filter housing 3260 passes through the filter 3270 and is then discharged to the outside through a plurality of discharge slots 3261.

[0266] As described above, when cleaning is performed using the portable stick vacuum cleaner 3000 according to the present embodiment, the second portion 3200 provided with the handle 3210 can be rotated at a certain angle around the rotation axis 3240 relative to the first portion 3100. Therefore, the bending or twisting operation of the wrist holding the handle 3210 of the second portion 3200 can be minimized, so that the load applied to the wrist can be greatly reduced.

[0267] In the above description, the portable stick vacuum cleaner 3000 has a structure such that air exhausted from the suction motor 3310 is exhausted to the outside through the handle 3210. However, as another example, the portable stick vacuum cleaner 3000 may be configured to cool the rechargeable battery 3250 with the exhausted air.

[0268] Fig.44 A portable stick vacuum cleaner 3000 having a structure for cooling a rechargeable battery 3250 provided in a second portion 3200 with exhausted air is illustrated.

[0269] Reference Fig.44 , the exhaust duct 3280 is provided above the rechargeable battery 3250. One end of the exhaust duct 3280 is connected to the connection part 3230 to communicate with the exhaust hole of the motor housing 3320, and the other end of the exhaust duct 3280 is connected to the filter housing 3260. The connection part 3230 provided with the exhaust duct 3280 may be provided with a guide flow channel for guiding the air exhausted from the exhaust hole of the housing 3320 to the exhaust duct 3280. At this time, an air channel for passing air is not provided inside the handle 3210.

[0270] Therefore, the air exhausted from the motor housing 3320 is exhausted to the outside through the exhaust duct 3280 and the filter housing 3260 without passing through the handle 3210. At this time, since the exhaust duct 3280 is provided on the upper side of the rechargeable battery 3250, the air exhausted from the motor housing 3320 directly contacts the rechargeable battery 3250, thereby cooling the rechargeable battery 3250.

[0271] When the rechargeable battery 3250 is cooled using the air exhausted from the suction motor 3310, the rechargeable battery 3250 can be effectively cooled.

[0272] In addition to the arrangement of the exhaust duct 3280, Fig.44 The portable stick vacuum cleaner 3000 shown in FIG. Figure 40 to Figure 43 The portable stick vacuum cleaner 3000 shown in FIG. 1 is the same as the portable stick vacuum cleaner 3000 shown in FIG. 1 , and thus a detailed description thereof is omitted.

[0273] Finally, refer to Figures 45 to 49 A portable stick vacuum cleaner 4000 according to an embodiment of the present disclosure is described.

[0274] Fig.45 is a diagram illustrating a portable stick vacuum cleaner according to another embodiment of the present disclosure. Fig.46 yes Fig.45 A cross-sectional view of a portable stick vacuum cleaner. Fig.47 is along Fig.46 2 is a cross-sectional view of a portable stick vacuum cleaner taken along line GG shown in FIG. Fig.48 It is shown Fig.45 A diagram showing a state in which the handle of a portable stick vacuum cleaner is rotated at a specific angle. Fig.49 It is shown Fig.45 sectional view of a modified example of a portable stick vacuum cleaner.

[0275] Reference Figure 45 to Figure 47 , a portable stick vacuum cleaner 4000 according to an embodiment of the present disclosure may include: a first part 4100 provided with a dust collecting member 4110 ; a second part 4200 provided with a handle 4210 and a rechargeable battery 4250 ; and a third part 4300 provided with a suction motor 4310 .

[0276] In detail, the first part 4100 includes a mounting portion 4120 and a dust collecting member 4110 disposed in the mounting portion 4120. An inlet 4121 is disposed at one side of the mounting portion 4120, and external air containing dust is sucked through the inlet 4121. An internal passage 4122 for guiding external air to the inlet 4113 of the dust collecting member 4110 is disposed between the inlet 4121 and the dust collecting member 4110. Fig.15The extension pipe 30 shown in FIG. 4 may be detachably connected to the inlet 4121 of the mounting portion 4120 . Therefore, external air is introduced into the dust collecting member 4110 through the inlet 4121 of the mounting portion 4120 and the internal passage 4122 .

[0277] The dust collecting member 4110 may include a cyclone 4111 for separating dust from incoming air by vortexing the incoming air, and a dust collecting chamber 4112 for collecting dust separated by the cyclone 4111. The dust collecting chamber 4112 may be detachably provided to the mounting portion 4120.

[0278] The dust collecting member 4110 is arranged in the mounting portion 4120 so that the cyclone 4111 is substantially perpendicular to the direction in which air is sucked into the inlet 4121 of the mounting portion 4120. Fig.46 As shown in FIG. 4 , the dust collecting member 4111 is arranged in the mounting portion 4120 so that the direction in which air is discharged from the discharge port 4114 of the cyclone 4111 is substantially perpendicular to the direction in which air is sucked into the internal passage 4122. Fig.15 When the extension pipe 30 is disposed in the inlet 4121 of the mounting portion 4120 , the cyclone 4111 of the dust collecting member 4110 is substantially perpendicular to the extension pipe 30 .

[0279] In addition, an exhaust passage 4123 for guiding the air exhausted from the dust collecting member 4110 to the suction motor 4310 is provided at the other side of the mounting portion 4120 (i.e., the opposite side of the mounting portion 4120), wherein the dust collecting member 4110 is interposed between the one side and the other side of the mounting portion 4120. The exhaust passage 4123 is provided in the mounting portion 4120 to guide the air exhausted from the exhaust port 4114 of the dust collecting member 4110 to the inlet of the suction motor 4310 in a direction substantially perpendicular to the direction in which the sucked air is sucked into the dust collecting member 4110.

[0280] The suction motor 4310 is provided in the third part 4300. The third part 4300 is integrally formed with the first part 4100, and includes a motor housing 4320 in which the suction motor 4310 is embedded. The motor housing 4320 may be provided with an inlet for communicating with the exhaust passage 4123 of the first part 4100, and an exhaust hole for exhausting the air having passed through the suction motor 4310 to the outside of the motor housing 4320. Therefore, the air sucked into the inlet of the motor housing 4320 of the third part 4300 passes through the suction motor 4310 and is then exhausted through the exhaust hole.

[0281] A pair of first support portions 4340 for supporting the rotation of the second portion 4200 may be provided at both ends of the motor housing 4320 of the third portion 4300 .

[0282] The second part 4200 is provided with a handle 4210 and a rechargeable battery 4250. The second part 4200 is formed to be rotatable relative to the third part 4300. For example, the second part 4200 may include a pair of second support parts 4220 corresponding to a pair of first support parts 4340 of the third part 4300 and a handle 4210 connected to the pair of second support parts 4220. The pair of second support parts 4220 and the handle 4210 are connected to each other by a connecting part 4230. The pair of first support parts 4340 and the pair of second support parts 4220 are rotatably connected to each other by a pair of rotating shafts 4240. At this time, the pair of rotating shafts 4240 may be arranged coaxially with the rotating shaft of the suction motor 4310 provided in the motor housing 4320 of the third part 4300.

[0283] Therefore, the handle 4210 of the second part 4200 can be rotated at a specific angle relative to the first part 4100 about a pair of rotation axes 4240. For example, the handle 4210 (eg, Fig.45 ) is rotated counterclockwise around a pair of rotation axes 4240 by a specific angle so that the mounting portion 4120 and the handle 4210 can form an acute angle (as shown in Fig.48 ).

[0284] Since the handle 4210, the rechargeable battery 4250 and the filter housing 4260 are disposed in the second portion 4200, Figure 40 to Figure 43 The handle 3210 , the rechargeable battery 3250 , and the filter housing 3260 of the portable stick vacuum cleaner 3000 shown in FIG. 1 are the same, and thus a detailed description thereof is omitted.

[0285] In addition, the third part 4300 may be provided with a mode setting member 4400, which is configured to set the first part 4100 and the second part 4200 to one of a rotation mode (in which the first part 4100 and the second part 4200 can rotate relative to each other) and a fixed mode (in which the first part 4100 and the second part 4200 are fixed to each other).

[0286] The first part 4100 and the second part 4200 can be fixed or rotated relative to each other by operating the mode setting member 4400. In addition, when the mode setting member 4400 is set to the rotation mode, the first part 4100 and the second part 4200 are arranged at a desired angle. Thereafter, when the mode setting member 4400 is set to the fixed mode, the first part 4100 and the second part 4200 can maintain the arranged angle. Since the structure and operation of the mode setting member 4400 are the same or similar to the structure and operation of the mode setting member 410 according to the above-mentioned embodiment, a detailed description thereof is omitted.

[0287] In the following, reference will be made to Fig.46 The operation of the portable stick vacuum cleaner 4000 according to an embodiment of the present disclosure is described.

[0288] When the suction motor 4310 is operated by power supplied from the rechargeable battery 4250, suction force is generated, and external air is sucked into the inlet 4121 of the mounting portion 4120. The sucked external air moves along the internal passage 4122 and enters the cyclone 4111 of the dust collecting member 4110.

[0289] While the external air passes through the cyclone 4111, dust and dirt contained in the external air are separated from the air and collected in the dust collecting chamber 4112. The cleaned air is introduced into the suction motor 4310 provided in the motor housing 4320 through the exhaust passage 4123 provided in the mounting portion 4120.

[0290] The air flowing into the suction motor 4310 is discharged through the discharge hole of the suction motor 4310. The air discharged from the suction motor 4310 is introduced into the filter housing 4260 through the air channel 4211 inside the handle 4210. The air introduced into the filter housing 4260 passes through the filter 4270 and is then discharged to the outside through a plurality of discharge slots 4261.

[0291] As described above, when cleaning is performed using the portable stick vacuum cleaner 4000 according to the present embodiment, the second portion 4200 provided with the handle 4210 can be rotated at a certain angle about the rotation axis 4240 relative to the first portion 4100. Therefore, the bending or twisting operation of the wrist holding the handle 4210 of the second portion 4200 can be minimized, so that the load applied to the wrist can be greatly reduced.

[0292] In the above description, the portable stick vacuum cleaner 4000 has a structure such that air exhausted from the suction motor 4310 is exhausted to the outside through the handle 4210. However, as another example, the portable stick vacuum cleaner 4000 may be configured to cool the rechargeable battery 4250 with the exhausted air.

[0293] Fig.49 A portable stick vacuum cleaner 4000 having a structure for cooling a rechargeable battery 4250 provided in a second portion 4200 with exhausted air is illustrated.

[0294] Reference Fig.49, the exhaust duct 4280 is disposed on the upper portion of the rechargeable battery 4250. One end of the exhaust duct 4280 is connected to the connection portion 4230 to communicate with the exhaust hole of the motor housing 4320, and the other end of the exhaust duct 4280 is connected to the filter housing 4260. The connection portion 4230 in which the exhaust duct 4280 is disposed may be provided with a guide flow passage for guiding air exhausted from the exhaust hole of the motor housing 4320 to the exhaust duct 4280. At this time, an air passage through which air passes is not provided inside the handle 4210.

[0295] Therefore, the air exhausted from the motor housing 4320 is exhausted to the outside through the exhaust duct 4280 and the filter housing 4260 without passing through the handle 4210. At this time, since the exhaust duct 4280 is provided on the upper side of the rechargeable battery 4250, the air exhausted from the motor housing 4320 directly cools the rechargeable battery 4250.

[0296] When the rechargeable battery 4250 is cooled using the air exhausted from the suction motor 4310, the rechargeable battery 4250 can be effectively cooled.

[0297] In the above, although the embodiments of the present disclosure have been shown and described, it should be understood that the present disclosure is not limited to the disclosed embodiments. It will be understood by those skilled in the art that various changes can be made in form and details without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents.
