It is a cross section.

Referring to FIG. 5, the locking unit 400 may be installed in the third portion 300. In detail, the mode setting member 410 of the locking unit 400 is disposed outside the third portion 300, and the remaining components of the locking unit 400 are formed inside the first portion 300. 2 between the support (320, 340).

The locking unit 400 may include a mode setting member 410, an elastic member 430, a latch 450, and a slider 470.

The mode setting member 410 is slidably disposed in the groove 329 (see FIG. 3) formed on the outer surface of the first support part 320 of the third part 300. The recess 329 is formed to be longer than the length of the mode setting member 410. In addition, the recess 329 is formed along the circumferential direction of the first support part 320. Accordingly, the mode setting member 410 may move to the first position corresponding to the fixed mode and the second position corresponding to the rotation mode in the recess 329.

The mode setting member 410 may be integrally formed with a non-slip protrusion 411 on the outer surface for the user's convenience of operation.

The mode setting member 410 may be fastened to the slider 470 through the screw 480. In this case, the mode setting member 410 has a fastening hole 413 to which the screw 480 is fastened to an inner surface thereof.

The elastic member 430 elastically presses the latch 450 toward the slider 470. The elastic member 430 is a coil spring, one end of which is inserted into the fixing groove 324 formed on the inner side surface of the first support part 320, and the other end of the elastic member 430, which includes the fixing protrusion 451 (see FIG. 6). )

The latch 450 is slidably disposed in the evacuation space 327 formed between the

guide ribs

325 and 326 formed on the inner side surface of the first support part 320.

As the latch 450 is elastically pressed toward the slider 470 by the elastic member 430, the latch 450 may slide toward the first support 320 or the second support 340 in association with the movement of the slider 470. .

The latch 450 has a contact surface 453 on the side facing the slider 470. The contact surface 453 may slide in contact with the first inclined surface 473 (see FIG. 6) and the second inclined surface 475 (see FIG. 6) of the slider 470, which will be described later.

When the latch 450 is inserted into the evacuation space 327 of the first support part 320, the first and

second support parts

100 and 200 may be rotatable with each other. Accordingly, the first and

second portions

100 and 200 may be set in the rotation mode.

On the other hand, when the latch 450 is completely separated from the evacuation space 327 and inserted into any one of the plurality of fixing grooves 345 formed in the second support part 340 as shown in FIG. 6, the first and second support parts ( 100,200 is in a state that can not rotate with each other. Accordingly, the first and

second portions

100 and 200 may be set in the fixed mode.

Referring to FIG. 5, the slider 470 has a through hole 471 to which the screw 480 is fastened. The slider 470 is fastened to the mode setting member 410 at predetermined intervals by the screw 480. In this case, an elastic member 430 and a latch 450 are disposed between the mode setting member 410 and the slider 470.

The first support part 320 is formed with a guide hole 323 through which the screw 480 for fastening the mode setting member 410 and the slider 470 to each other can be moved. Accordingly, when the mode setting member 410 is moved to the first position (see FIGS. 6 and 7) for setting the fixed mode or the second position (see FIGS. 8 and 9) for setting the rotation mode, The slider 470 also moves together with the mode setting member 410 to move to the first position or the second position.

6 and 7, the slider 470 has first and second

inclined surfaces

473 and 475 inclined in the same direction on the side facing the latch 450. The first inclined surface 473 is located closer than the second inclined surface 475 based on the one surface 340a of the second support part 340.

When the mode setting member 410 moves to the first position (fixed mode), the slider 470 slides along one surface 340a of the second support part 340 such that the first inclined surface 473 latches 450. At a position corresponding to the contact surface 453 of. In this case, the latch 450 is completely removed from the space 327 (see FIG. 5), and then inserted into one of the plurality of fixing grooves 345. Accordingly, the first and

second support parts

320 and 340 are locked to each other, and the first and

second parts

100 and 200 are not rotatable about the rotation axis 360.

8 and 9, when 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 part 340 to move the second. The inclined surface 475 comes at a position corresponding to the contact surface 453 of the latch 450. In this case, the latch 450 is inserted into the evacuation space 327 (see FIG. 5). Accordingly, since the first and

second support parts

320 and 340 are released from each other, the first and

second parts

100 and 200 are rotatable with each other.

In this state, if the mode setting member 410 is moved to the first position after the first and

second parts

100 and 200 are rotated at a predetermined angle about the rotation shaft 360, the latch 450 may have a plurality of fixing grooves ( 345 and is interlocked with the first and

second supports

320, 340. Therefore, the first and

second parts

100 and 200 are not rotatable about the rotation axis 360.

However, it is of course possible to clean the state in which the mode setting member 410 is moved to the second position. In this case, the first part 100 may be continuously rotated at an angle with respect to the rotation axis 360 with respect to the second part 200.

Hereinafter, referring to FIGS. 3 and 4, a structure in which the first and

second portions

100 and 200 are connected to the air through the flexible tube 500 will be described.

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 rear end 530 is connected to the front end of the second part 200, thereby providing the first and

second parts

100 and 200. Can be connected to allow for mutual ventilation.

The flexible tube 40 corresponding to the section between the first and

second portions

100 and 200 of the suction passage (refer to FIG. 10) may be rotated when the first and

second portions

100 and 200 rotate about the rotation axis 360. The suction path can be maintained while bending naturally.

In this case, the flexible tube 500 so that air does not leak from the connection portion of the one end 510 and the first portion 100 of the flexible tube and the connection portion of the other end 530 and the second portion 200 of the flexible tube. ) Needs a structure that is firmly connected to the first and

second portions

100 and 200.

To this end, the flexible tube 500 may be formed with a spiral protrusion on the outer periphery. The spiral protrusion may be formed on the entire outer circumference of the flexible tube 500 or may be formed only at one end 100 and the other end 100 of the flexible tube. The first portion 100 has a first coupling member 130 (see FIG. 3) in which one end 510 of the flexible tube is screwed to the rear end thereof, and the second portion 200 has the other end 530 of the flexible tube at the front end thereof. ) Is coupled to the second coupling member 230 (see FIG. 4). The first and

second coupling members

130 and 230 are each formed with a threaded portion on its inner circumferential surface.

The flexible tube 500 has one end 510 screwed to the first coupling member 130 and the other end 530 is screwed to the second coupling member 230. Accordingly, even if the first and

second portions

100 and 200 rotate repeatedly about the rotation axis 360, one end 510 and the other end 530 of the flexible tube are not separated from the first and

second coupling members

130 and 230. It is possible to maintain a firm coupling with the first and second coupling members (130,230) without (see Figure 10).

On the other hand, the flexible tube 500 is bent when the first and

second portions

100 and 200 rotate with each other. At this time, if the inside of the bent portion of the flexible tube 500 is excessively narrowed, the suction efficiency may decrease. . Therefore, in order to prevent the suction efficiency from being lowered, the shape maintaining member (not shown) may be coupled to the inside of the flexible tube 500. The shape retaining member may be formed in a coil spring shape formed in a spiral so as to be coupled along a spiral groove formed inside the flexible tube 500. Here, the helical groove corresponds to the inside of the helical protrusion protruding from the outer circumference of the flexible tube 500.

In addition, the flexible tube 500 may omit the shape maintaining member. In this case, it is preferable that the material of the flexible tube 500 is made of a material capable of maintaining a predetermined strength, or made of a Zaraba shape that is easily stretched and bent.

In the fixed mode, the cyclone part S1, the flexible tube 500, and the suction motor 250 may be arranged in a line. In this case, the central axis X1 (see FIG. 10) of the cyclone part S1 and the central axis X2 (see FIG. 10) of the suction motor 250 may be disposed in parallel or concentrically with each other. In addition, in the rotation mode, the central axis X1 of the cyclone part S1 and the central axis X2 of the suction motor 250 may be disposed at an obtuse angle.

Hereinafter, referring to FIGS. 10 to 14, the structures of the first part 100 and the second part 200 of the handy-stick vacuum cleaner 10 will be described in detail.

10 and 11A, the first portion 100 has a suction hole 103 into which air including dust flows into one end of the tip portion 101. If cleaning is performed using the extension tube 30 as shown in FIG. 15, one end of the extension tube 30 may be inserted into the suction hole 103 and installed in the inner passage 102 of the tip portion 101.
