As an example, the locking protrusion 131 may be separably inserted into the plurality of locking grooves 122. For example, the locking protrusion 131 may be provided in the shape of a protrusion extending along the second direction (Y) perpendicular to the first direction (N).

The locking protrusion pressing unit 132 is a pressing member that applies pressure to the locking protrusion 131. As an example, the locking protrusion pressing portion 132 may be supported to slide along the first direction (N) or the direction opposite to the first direction (-N) with respect to the locking protrusion support portion 135. At this time, the locking protrusion pressing portion 132 may receive pressure from the push button portion 133 and move along the first direction (N).

The push button unit 133 may move along the second direction (Y) perpendicular to the first direction (N) by pressure applied from the outside. As an example, the push button unit 133 may be disposed on the outer peripheral surface of the first extension pipe 110 to protrude in a direction (-Y) opposite to the second direction. Accordingly, the push button portion 133 may be supported on the push button support portion 134 supported on the outer peripheral surface of the upper end of the first extension pipe 110 to be movable along the second direction (Y). For example, the push button unit 133 may move along the second direction (Y) by receiving pressure from the lock release unit 230.

The push button support part 134 may be arranged to be fixed to the outer peripheral surface of the first extension tube 110. According to one example, the push button portion protrusion 1330 may be arranged to be inserted into the push button support portion penetration hole 1340 provided in the push button support portion 134. Accordingly, the push button protrusion 1330 can guide the movement path of the push button unit 133. Additionally, the push button protrusion 1330 may apply pressure to the locking protrusion pressing portion guide portion 1320 provided on the locking protrusion pressing portion 132.

Accordingly, the locking protrusion 131 may be arranged to be inserted into the locking protrusion through-hole 1350 and supported to move along the second direction (Y) or the direction opposite to the second direction (-Y). Hereinafter, the locking position (L ₁ ) and unlocking position (L ₂ ) of the locking device 130 will be described in more detail with reference to FIGS. 3C to 3E.

Referring to FIG. 3C, the locking protrusion 131 is disposed along the second direction (Y) or the direction opposite to the second direction (-Y) with respect to the locking protrusion support portion 135 supported on the outer periphery of the first extension pipe 110. It can be supported so that it can slide. Additionally, the push button portion 133 may be disposed on the outer peripheral surface of the first extension pipe 110 to protrude along a direction (-Y) opposite to the second direction perpendicular to the first direction (N).

As an example, the locking protrusion 131 may be separably inserted into a plurality of locking grooves 122 arranged along the longitudinal direction of the second extension tube 120, for example, in the first direction (N). For example, as shown in FIG. 3C, the locking protrusion 131 may be inserted into any one of the plurality of locking grooves 122. When the locking protrusion 131 is inserted into any one of the plurality of locking grooves 122, the locking device 130 may be placed in the locking position (L ₁ ). At this time, the position of the second extension pipe 120 relative to the first extension pipe 110 may be fixed.

Referring to FIGS. 3B, 3D, and 3E, pressure may be applied to the locking device 130 according to an example in the second direction Y. At this time, the pressure applied to the locking device 130 may be provided from the unlocking unit 230 as the vacuum cleaner 1 and the docking station 2 are coupled.

At this time, the push button portion protrusion 1330 provided on the push button portion 133 may pass through the push button support portion hole 1340 and apply pressure to the locking protrusion pressing portion guide portion 1320. As pressure is applied to the locking protrusion pressing part guide part 1320, the locking protrusion pressing part 132 may rise along the first direction (N). As the locking protrusion pressing portion 132 moves along the first direction (N), the pressure applied to the locking protrusion 131 along the second direction (Y) is released, and the locking protrusion 131 supports the locking protrusion. It may move in the direction opposite to the second direction (-Y) along the guide 1351. Accordingly, the locking protrusion 131 may separate from the plurality of locking grooves 122. When the locking protrusion 131 deviates from the plurality of locking grooves 122, the locking device 130 may be disposed in the unlocked position (L ₂ ). At this time, the second extension pipe 120 may move along the first direction (N) or the direction opposite to the first direction (-N) with respect to the first extension pipe 110.

When the combination of the vacuum cleaner 1 and the docking station 2 is released and the pressure applied to the locking device 130 is released, the locking protrusion pressurizing portion 132 is moved to the first position by the elastic force of the elastic member (not shown). You can descend in the opposite direction (-N). At this time, the push button unit 133 may be returned to its original position along the direction (-Y) opposite to the second direction. As the locking protrusion pressing portion 132 descends in a direction (-N) opposite to the first direction, pressure may be applied to the locking protrusion 131 in the second direction (Y). Accordingly, the locking protrusion 131 can move along the second direction (Y). At this time, the locking protrusion 131 may be inserted into any one of the plurality of locking grooves 122. When the locking protrusion 131 is inserted into any one of the plurality of locking grooves 122, the locking device 130 may be placed in the locking position (L ₁ ) again.

Referring to FIGS. 5A and 5B, the extension tube assembly clamp 240 is a position that fixes the position of the extension tube assembly 100 to the extension tube assembly receiving portion 220 as the cleaner 1 is connected to the docking station 2. It is a fixed member. As an example, when the vacuum cleaner 1 is connected to the docking station 2, the extension tube assembly 100 may pass through the second opening 222 and be seated in the second receiving portion 221. In order to fix the position of the extension tube assembly 100 accommodated in the second receiving portion 221, the extension tube assembly clamp 240 may support the extension tube assembly 100.

As an example, the extension pipe assembly clamp 240 may include a first clamp 241 and a second clamp 242 that are arranged to be spaced apart at a predetermined distance therebetween. For example, the first clamp 241 and the second clamp 242 may be arranged to be spaced apart from each other with the second opening 222 therebetween. Accordingly, the extension tube assembly 100 can enter or exit between the first clamp 241 and the second clamp 242.

The first clamp 241 may be arranged to be rotatable about one axis 2410. For example, when the extension tube assembly 100 enters or exits between the first clamp 241 and the second clamp 242, the first clamp 241 and the extension tube assembly rotate around one axis 2410. (100) It is possible to prevent interference between At this time, a first roller 243 may be disposed at one end of the first clamp 241. As the first roller 243 rotates while contacting the outer peripheral surface of the extension tube assembly 100, the extension tube assembly 100 can more easily enter or exit between the first clamp 241 and the second clamp 242. Additionally, after the first clamp 241 rotates about one axis 2410, an elastic member (not shown) may be disposed to apply a restoring force so that the first clamp 241 can return to its original position. For example, the elastic member (not shown) may be a torsion spring disposed on one axis 2410, but the present disclosure is not limited thereto. A driving device that applies a restoring force through a driving force may be disposed instead of an elastic member (not shown). Additionally, one surface of the first clamp 241 may have a shape corresponding to the outer peripheral surface of the extension tube assembly 100.

The second clamp 242 may be arranged to be rotatable about one axis 2420. For example, when the extension tube assembly 100 enters or exits between the first clamp 241 and the second clamp 242, the second clamp 242 and the extension tube assembly rotate around one axis 2420. (100) It is possible to prevent interference between At this time, a second roller 244 may be disposed at one end of the second clamp 242. The technical feature of allowing the extension tube assembly 100 to more easily enter or exit between the first clamp 241 and the second clamp 242 by rotating the second clamp 242 around one axis 2420 is the first. Since it is substantially the same as the clamp 241, description is omitted here.

6A is a partial front view of a docking station according to one embodiment. 6B is a partial perspective view of a vacuum cleaner and a docking station according to one embodiment.

Referring to FIGS. 6A and 6B, the position guide groove 250 is a guide member that engages with the position fixing guide protrusion 170 included in the cleaner 1 as the cleaner 1 is connected to the docking station 2. . According to one example, when the position fixing guide protrusion 170 and the position guide groove 250 are arranged to engage with each other, the position of the vacuum cleaner 1 with respect to the docking station 2 may be fixed.

As an example, the position guide groove 250 may be disposed at a position corresponding to the position fixing guide protrusion 170 included in the vacuum cleaner 1. According to one example, the position fixing guide protrusion 170 may be disposed on one side of the suction unit 13. At this time, the position guide groove 250 may be disposed on at least one side of the suction unit accommodating part 210. For example, as shown in FIG. 6A, when the positioning guide protrusion 170 is arranged to protrude from the rear of the suction unit 13, the position guide groove 250 is provided in the shape of a step to accommodate the suction unit receiving portion 210. ) can be placed on the bottom of the. However, the present disclosure is not limited to this, and the position guide groove 250 may be provided in any structure corresponding to the position fixing guide protrusion 170.

According to one example, a roller unit 171 may be disposed at one end of the position guide protrusion 170. As the roller unit 171 is disposed at one end of the position guide protrusion 170, when the user removes the vacuum cleaner 1 from the docking station 2, the position guide protrusion 170 moves the roller unit 171. Accordingly, it can be more easily separated from the position guide groove 250.

7A is a partial perspective view of a docking station according to one embodiment. 7B is a partial projection perspective view of a docking station according to one embodiment. 7C is a partial perspective view of a vacuum cleaner and docking station according to one embodiment.

Referring to FIGS. 7A to 7C, the shock absorber 260 absorbs shock that may occur between the vacuum cleaner 1 and the docking station 2 as the vacuum cleaner 1 is connected to the docking station 2. There is no shock cushioning. As an example, when the cleaner 1 is connected to the docking station 2, the second extension tube 120 moves toward the first extension tube 110 due to the weight of the cleaner main body 11 and the dust collection container 12. It can be inserted along the direction opposite to direction 1 (-N). At this time, an impact may occur when the upper surface of the docking station 2 and the lower surface of the cleaner main body 11 or the dust collection container 12 contact each other. The shock absorber 260 according to one example may be arranged to protrude from the upper surface of the docking station 2. For example, when the cleaner 1 is connected to the docking station 2, the shock absorber 260 may be disposed to face the lower surface of one or more of the cleaner main body 11 or the dust collection container 12. Accordingly, the shock absorber 260 can absorb the shock between the upper surface of the docking station 2 and the lower surface of the cleaner main body 11 or the dust collection container 12.

As an example, the shock absorber 260 may include a case portion 261 and a restoring force application device 262 that applies a restoring force to the case portion 261. For example, the case portion 261 may include a rigid material. Additionally, the case portion 261 may be arranged to be rotatable about one axis 2610. A roller member 2611 may be disposed at one end of the case portion 261. The roller member 2611 may absorb shock during contact with the lower surface of one or more of the cleaner body 11 or the dust collection container 12. A first gear unit 2612 is disposed at the other end of the case unit 261 to receive power from the restoring force application device 262.

The restoring force application device 262 may include a driving motor 2620 and a second gear unit 2622 that receives power from the driving motor 2620. The second gear unit 2622 is connected to the rotation shaft of the drive motor 2620 and can receive power. The second gear unit 2622 may be arranged to engage with the first gear unit 2612. Accordingly, power can be transmitted from the second gear unit 2622 to the first gear unit 2612.

As an example, when the cleaner 1 is connected to the docking station 2, the lower surface of one or more of the cleaner main body 11 or the dust collection container 12 may contact the upper surface of the case portion 261. At this time, the case portion 261 may rotate clockwise around one axis 2610. Also, at this time, the drive motor 2620 may generate power and transmit the power to the second gear unit 2622. The second gear unit 2622 may transmit power through the first gear unit 2612. Accordingly, the case portion 261 may receive rotational force along a counterclockwise direction about one axis 2610. As the lower surface of one or more of the cleaner body 11 or the dust collection container 12 contacts the upper surface of the case part 261, the case part 261 rotates clockwise around one axis 2610. The rotational speed may be reduced by the rotational force applied through the first gear unit 2612. Accordingly, the impact generated during contact between the upper surface of the docking station 2 and the lower surface of one or more of the cleaner main body 11 or the dust collection container 12 can be alleviated.

Additionally, as another example, the shock absorber 260 may include a buffer material that is deformed when pressure is applied and can be restored when the pressure is released. For example, the shock absorber 260 may include an elastic material with a high elastic modulus, such as rubber. Additionally, the shock absorber 260 may include a member with high restoring elastic force, such as a spring.

Hereinafter, a structure in which the extension tube assembly 100 is reduced as the vacuum cleaner 1 is connected to the docking station 2 will be described.

Figure 8A is a side view of a first step in which the vacuum cleaner is connected to the docking station, according to one example. 8B is a side view of a second step in which the vacuum cleaner is connected to the docking station according to one example. Figure 8C is a side view of a third step in which the vacuum cleaner is connected to the docking station according to one example.

Referring to FIG. 8A , according to one example, when the vacuum cleaner 1 is connected to the docking station 2, the suction unit 13 may enter through the first opening 212. The suction unit 13 that has passed through the first opening 212 may be seated in the first receiving portion 211. At this time, as shown in FIG. 6B, the position fixing guide protrusion 170 included in the vacuum cleaner 1 and the position guide groove 250 included in the docking station 2 may be engaged with each other. Accordingly, the position of the suction unit 13 within the first receiving portion 211 can be fixed.

Referring to FIG. 8B, after the suction unit 13 is seated in the first receiving portion 211 according to one embodiment, the extension tube assembly 100 may rotate counterclockwise toward the second opening 222. there is. At this time, the unlocking unit 230 and the locking device 130 may contact each other, and pressure may be applied to the locking device 130 in the second direction Y, as shown in FIG. 3D. As pressure is applied to the locking device 130 along the second direction (Y), the locking protrusion 131 may move along the opposite direction (-Y) of the second direction. Accordingly, as shown in FIG. 3E, the locking protrusion 131 may be separated from the plurality of locking grooves 122. Accordingly, the locking device 130 may be placed in the unlocked position L ₂ .

Referring to FIG. 8C, as the locking device 130 according to one example is disposed in the release position (L ₂ ), the second extension pipe 120 moves in a direction opposite to the first direction with respect to the first extension pipe 110 (- You can move along N). At this time, an impact may occur when the upper surface of the docking station 2 and the lower surface of the cleaner main body 11 or the dust collection container 12 contact each other. The shock absorber 260 according to one example contacts the lower surface of one or more of the cleaner body 11 or the dust collection container 12, thereby contacting the upper surface of the docking station 2 and the cleaner main body 11 or the dust collection container 12. It can absorb shock between the lower surfaces of the. According to one example, the overall length of the extension tube assembly 100 is reduced, so that the lower surface of the dust collection container 12 can be coupled to the docking station 2.

As described above, when connecting the vacuum cleaner 1 to the docking station 2, the locking device 130 will be automatically placed in the unlocked position L ₂ by entering the vacuum cleaner 1 into the docking station 2. You can. Accordingly, the user can reduce the overall length of the extension tube assembly 100 without manipulating the locking device 130, thereby improving user convenience.

Figure 9 is a front view of a vacuum cleaner and a docking station according to another example. Figure 10 is a side view of a vacuum cleaner according to another example. Figure 11A is a partial perspective view of a vacuum cleaner according to another example. Figure 11b is an exploded perspective view of an extension tube assembly according to another example.

Referring to FIGS. 9 to 11B , a cleaning device C' according to another example may include a vacuum cleaner 3 and a docking station 4.

The cleaner 3 according to another example includes a cleaner main body 31, a dust collection bin 32 coupled to the cleaner main body 31, an extension tube assembly 300 detachably coupled to the cleaner main body 31, and an extension tube assembly ( It may include a suction unit 33 that is detachably coupled to 300). The cleaner 3 according to another example may be a vacuum cleaner that absorbs foreign substances using suction pressure, but the present disclosure is not limited thereto. Except for the extension tube assembly 300, the remaining cleaner main body 31, dust collection container 32, and suction unit 33 are shown in FIGS. 2 to 3B. ), so the description is omitted here.

The extension tube assembly 300 is disposed between the cleaner main body 31 and the suction unit 33 and can transfer foreign substances sucked from the suction unit 33 to the cleaner main body 31. The extension tube assembly 300 according to one example may have an upper end connected to communicate with the cleaner main body 31 and a lower end connected to communicate with the suction unit 33.

As an example, the extension tube assembly 300 may include a first extension tube 310, a second extension tube 320, a locking device 330, and a guide unit 340. The first extension pipe 310 and the second extension pipe 320, excluding the locking device 330 and the guide portion 340, are substantially similar to the first extension pipe 110 and the second extension pipe 120 shown in FIGS. 2 to 3B. Since it is the same, the description is omitted here.

The locking device 330 allows the user to adjust the overall length of the extension tube assembly 300, that is, the overall length of the first extension tube 310 and the second extension tube 320, to a desired length. Make sure to maintain the adjusted length. As an example, the locking device 330 is installed on the outer peripheral surface of the upper end of the first extension pipe 310, and is connected to the first extension pipe 310 and the second extension pipe 320 while the second extension pipe 320 is inserted into the first extension pipe 310. Movement between the second extension pipes 320 may be selectively restricted. For example, the locking device 330 selectively slides the second extension pipe 320 along the first direction (N) or the direction opposite to the first direction (-N) with respect to the first extension pipe 310. It can be limited.

The locking device 330 according to one example may include a locking protrusion 331, a locking protrusion support portion 332, and a locking release portion 333.

It can be supported. Accordingly, the locking protrusion 331 may be arranged to be able to slide along the radial direction of the first extension tube 310 with respect to the first extension tube 310 .

As an example, the locking protrusion 331 may be separably inserted into a plurality of locking grooves 322 arranged along the longitudinal direction of the second extension pipe 320, for example, in the first direction (N). For example, as shown in FIG. 14A, the locking protrusion 331 may be inserted into any one of the plurality of locking grooves 322. At this time, the pressure applying part 3331 included in the unlocking part 333 has a locking protrusion along the second direction (Y) perpendicular to the first direction (N), for example, along the radial direction of the first extension pipe 310. Pressure can be applied to (331). When the locking protrusion 331 is inserted into any one of the plurality of locking grooves 322, the locking device 330 may be placed in the locking position (L1: see FIG. 14A). At this time, the position of the second extension pipe 320 with respect to the first extension pipe 310 may be fixed. Additionally, as shown in FIG. 14B, the locking protrusion 331 may slide along a direction (-Y) opposite to the second direction and separate from the plurality of locking grooves 322. At this time, the pressure applying part 3331 included in the unlocking part 333 does not apply pressure to the locking protrusion 331. When the locking protrusion 331 slides in the direction opposite to the second direction (-Y) and deviates from the plurality of locking grooves 322, the locking device 330 will be placed in the unlocked position (L2: see Figure 14b). You can. At this time, the second extension pipe 320 may move along the first direction (N) or the direction opposite to the first direction (-N) with respect to the first extension pipe 310.

According to one example, the lock release unit 333 may receive pressure from the outside along the first direction (N) or the direction opposite to the first direction (-N). Accordingly, the lock release unit 333 may move along the first direction (N) or the direction opposite to the first direction (-N) with respect to the first extension pipe 310. As the unlocking unit 333 moves along the first direction (N) or the direction opposite to the first direction (-N) with respect to the first extension pipe 310, the pressure applying unit included in the unlocking unit 333 The position of 3331 may also be changed along the first direction (N) or the direction opposite to the first direction (-N). By changing the position of the pressure applicator 3331, pressure may be applied to the locking protrusion 331 or the pressure applied to the locking protrusion 331 may be released.

The guide unit 340 is arranged to be fixed to the locking device 330 and can guide the movement path of the locking device 330. As an example, the guide unit 340 may guide the locking device 330 to move along the first direction (N) or the direction opposite to the first direction (-N). The guide part 340 according to one example may have a protrusion shape extending along the outer peripheral surface of the first extension tube 310. For example, the guide unit 340 may be provided in a ring shape into which the first extension tube 310 is inserted. The guide unit 340 may move along the outer peripheral surface of the first extension tube 310 in the first direction (N) or in the direction opposite to the first direction (-N). Accordingly, the locking device 330 fixed to the guide portion 340 may also move along the outer peripheral surface of the first extension pipe 310 in the first direction (N) or in the direction opposite to the first direction (-N).

12 is a partial perspective view of a docking station according to another example.

Referring to FIG. 12 , the docking station 4 according to one example may include an extension tube assembly receiving portion 420 and a lock release portion 430. The extension tube assembly receiving portion 420 is a housing member that can accommodate the extension tube assembly 300 included in the vacuum cleaner 3. As an example, the extension tube assembly accommodating part 420 may include a receiving part 421 in which the extension tube assembly 300 is accommodated and an opening 422 through which the extension tube assembly 300 can enter. The receiving portion 421 according to one example may extend along one direction to correspond to the extension tube assembly 300. However, the present disclosure is not limited to this, and the accommodating portion 421 may be provided in a shape having an arbitrary accommodating space in which the extension tube assembly 300 can be placed. The opening 422 according to one example may be provided on one side of the receiving portion 421.

As the cleaner 3 is connected to the docking station 4, the lock release unit 430 contacts the guide unit 340 and moves the guide unit 340 in the first direction (N) or in the direction opposite to the first direction (- It can be moved along N). The lock release unit 430 according to one example may include a first unlock unit 431 and a second unlock unit 432 that are arranged to be spaced apart from each other at a predetermined interval. For example, the first release part 431 and the second release part 432 may be arranged to be spaced apart from each other with the opening 422 therebetween. Accordingly, the extension tube assembly 300 can enter or exit between the first release part 431 and the second release part 432.

According to one example, the first release part 431 and the second release part 432 may be disposed to protrude from the side of the opening 422. At this time, the first release part 431 and the second release part 432 may be arranged to face each other with the opening 422 in between. As an example, when the vacuum cleaner 3 is coupled to the docking station 4, the first release part 431 and the second release part 432 are connected to one side of the guide part 340, for example, the guide part 340. ) is disposed to face the lower surface of the guide unit 340 to apply pressure so that it moves along the first direction (N). As the guide portion 340 moves along the first direction (N), the locking device 330 moves along the first direction (N), so that the locking device 330 moves to the locking position (L ₁ : see FIG. 14A). It can be moved to the release position (L ₂ : see Figure 14b). Accordingly, the second extension tube 320 is inserted into the first extension tube 310 and the extension tube assembly 300 can be reduced. Hereinafter, a structure in which the extension tube assembly 300 is reduced as the vacuum cleaner 3 is connected to the docking station 4 will be described.

Figure 13 is a side view of a vacuum cleaner connected to a docking station according to another example. Figure 14A is a partial cross-sectional view of the vacuum cleaner in a locked position according to another example. 14B is a partial cross-sectional view of the vacuum cleaner in the released position according to another example.

Referring to FIG. 13, according to another example, when the vacuum cleaner 3 is connected to the docking station 4, the extension tube assembly 300 enters the opening 422 and moves in the direction opposite to the first direction (-N). You can move. At this time, the unlocking unit 430 and the guide unit 340 may come into contact. For example, when the lock release part 430 includes a first release part 431 and a second release part 432 disposed on the side of the opening 422, it protrudes from the outer peripheral surface of the first extension pipe 310. The lower surface of the guide part 340 arranged so as to be in contact with the first release part 431 and the second release part 432. The guide part 340 in contact with the first release part 431 and the second release part 432 may receive an external force along the first direction (N). Accordingly, the guide unit 340 can slide in the first direction (N) along the outer peripheral surface of the first extension tube 310.

As the guide part 340 slides in the first direction (N), the locking device 330 fixed to the guide part 340 slides in the first direction (N) along the outer peripheral surface of the first extension tube 310. You can move. As the first locking device 330 slides in the first direction (N) along the outer peripheral surface of the first extension tube 310, the locking protrusion 331 forms a plurality of locking grooves 322, as shown in FIG. 14B. may be separated from, and thus the locking device 330 may be placed in the unlocked position (L ₂ ).

As the locking device 330 according to one example is disposed in the unlocked position (L ₂ ), the second extension pipe 320 may move along a direction (-N) opposite to the first direction with respect to the first extension pipe 310. there is. As an example, the user applies an external force or by the gravity of the dust collection container 32. The second extension tube 320 may be inserted into the first extension tube 310. Accordingly, the overall length of the extension tube assembly 300 may be reduced. According to one example, the overall length of the extension tube assembly 300 is reduced, so that the lower surface of the dust collection container 32 can be coupled to the docking station 4.

As described above, when connecting the vacuum cleaner 3 to the docking station 4, the locking device 330 will be automatically placed in the unlocked position (L ₂ ) by entering the vacuum cleaner 3 into the docking station 4. You can. Accordingly, the user can reduce the overall length of the extension tube assembly 300 without manipulating the locking device 330, thereby improving user convenience.
