(15) Hereinafter, a pipe 100, which is easy to assemble and separate, according to an embodiment of the present disclosure will be described with reference to FIGS. 1 to 3.

(16) Referring to FIG. 1, the pipe 100 that is easy to assemble and separate includes a rear end pipe 110 formed in a cylindrical shape, an insertion pipe 120 located at the other end of the rear end pipe 110, and a front end pipe 130 that has one end into which the insertion pipe 120 is inserted and is connected to the rear end pipe 110. The other end described above may indicate a 6-o'clock direction of FIG. 1, and the one end may indicate a 12-o'clock direction of FIG. 1. In other words, the front end pipe 130 and the rear end pipe 110 may communicate with each other as the insertion pipe 120 is inserted into the front end pipe 130.

(17) In addition, the pipe, which is easy to assemble and separate, may include a first fixed portion 124 that is located at one end of the insertion pipe 120 and has magnetism and a second fixed portion 131 that is located in the front end pipe 130 to correspond to the first fixed portion 124 when the insertion pipe 120 is inserted into the front end pipe 130. In addition, the rear end pipe 110 and the front end pipe 130 may be fixed by a magnetic force generated between the first fixed portion 124 and the second fixed portion 131.

(18) In addition, one of the first fixed portion 124 or the second fixed portion 131 may be a magnet having a magnetic force, and the other may be a ferromagnetic material. For example, when the first fixed portion 124 is a magnet, the second fixed portion 131 is a ferromagnetic material, and when a distance between the first fixed portion 124 and the second fixed portion 131 is reduced to a certain distance or less, the front end pipe 130 may be fixed without being separated from the insertion pipe 120 by pulling the second fixed portion 131 by using a magnetic force of the first fixed portion 124. In contrast to this, when the second fixed portion 131 is a magnet, the first fixed portion 124 is a ferromagnetic material, and when the distance between the first fixed portion 124 and the second fixed portion 131 is reduced to a certain distance or less, the front end pipe 130 may be fixed without being separated from the insertion pipe 120 by pulling the first fixed portion 124 by using a magnetic force of the second fixed portion 131.

(19) However, the present disclosure is not limited thereto, and both the first fixed portion 124 and the second fixed portion 131 may be magnets having a magnetic force. In this case, the first fixed portion 124 and the second fixed portion 131 may have surfaces which face each other and have polarities different from each other. For example, the above-described magnet may be a neodium magnet but is not limited thereto.

(20) In other words, the front end pipe 130 and the insertion pipe 120 may be fixed by the magnetic forces of the first fixed portion 124 and the second fixed portion 131, and when a user rotates the front end pipe 130 or the rear end pipe 110 by using a force greater than the magnetic force, the first fixed portion 124 and the second fixed portion 131 may be separated from each other.

(21) An outer diameter of the insertion pipe 120 may be formed to be smaller than an outer diameter of the rear end pipe 110 and may be formed to be equal to an inner diameter of the front end pipe 130. Accordingly, when the insertion pipe 120 is inserted into the front end pipe 130, an outer surface of the insertion pipe 120 may come into close contact with an inner surface of the front end pipe 130.

(22) Referring to FIG. 2, the rear end pipe 110 may have a shape in which the other end is obliquely cut, and the front end pipe 130 may have a shape in which one end is obliquely cut to correspond to the rear end pipe 110.

(23) Referring to FIG. 3, when the suction pipe 100 is separated, the rear end pipe 110 and the front end pipe 130 are separated from each other by rotating the rear end pipe 110 or the front end pipe 130, and accordingly, there is an effect that the front end pipe 130 may be easily separated.

(24) Referring to FIG. 4, the pipe 100 for easy assembly and separation according to the present disclosure may be a suction pipe 100 having one end that is connected to a main body 11 of a vacuum cleaner 10 and transmits a suction force generated by the main body 11 of the vacuum cleaner 10.

(25) Hereinafter, the suction pipe 100 for a vacuum cleaner according to an embodiment of the present disclosure will be described with reference to FIGS. 4 to 7.

(26) Referring to FIG. 4, the vacuum cleaner 10 is an apparatus that sucks dust on a floor by using a vacuum generated by rotation of an electric blower mounted on the main body 11.

(27) The vacuum cleaner 10 may include a suction nozzle 12 that comes into contact with a bottom surface to suck dust, the suction pipe 100 connected to the suction nozzle 12, a hose portion 13 that is connected between the suction pipe 100 and the main body 11 and is formed of a flexible material, and the main body 11 that includes an electric blower for generating a suction force of the vacuum cleaner and a built-in dust filter for collecting the sucked dust.

(28) When the vacuum cleaner operates, the electric blower of the main body 11 may rotate to generate a vacuum for generating a suction force, and the generated suction force may be sequentially transmitted to the hose portion 13, the suction pipe 100, and the suction nozzle 12 to suck dust on the floor.

(29) In addition, a handle 14 may be formed at an end of the hose portion 13, and a controller for adjusting the suction force may be located in the handle 14.

(30) The vacuum cleaner 10 illustrated in FIG. 4 may be a wired cleaner generally used at home, and the present disclosure may include the suction pipe 100 mounted in a handy vacuum cleaner 10 used wirelessly. In the handy vacuum cleaner 10, the suction pipe 100 may be directly connected to the main body 11 to transmit a suction force generated by the main body 11 to the suction nozzle 12.

(31) Referring to FIG. 4, the rear end pipe 110 may have a cylindrical shape, and one end thereof may be connected to the main body 11 or the hose portion 13 of the vacuum cleaner 10.

(32) Referring to FIGS. 5 to 6B, the insertion pipe 120 may include a cylindrical portion 121 having a cross-section of a cylindrical shape, and an elliptical portion 122 that extends in a direction of the other side from the cylindrical portion 121 and has an elliptical cross-section and has a long axis becoming longer as going from one side to the other and has a short axis becoming shorter as going from the one side to the other. That is, the insertion pipe 120 may have the other end formed in an elliptical cylindrical shape, and thereby, it is possible to easily clean a window frame or a gap.

(33) In addition, the insertion pipe 120 may be made of a flexible material, and the end of the elliptical portion 122 may be transformed into a circular shape when inserted into the front end pipe 130. In addition, when the insertion pipe 120 is separated from the front end pipe 130, the insertion pipe 120 may return to an original shape by a restoring force.

(34) In addition, an outer circumferential length of the insertion pipe 120 may be the same as an inner circumferential length of the front end pipe 130. In addition, an outer circumferential length of the cylindrical portion 121 may be the same as an outer circumferential length of the elliptical portion 122, and thereby, when the insertion pipe 120 is inserted into the front end pipe 130, an outer surface of the insertion pipe 120 may be in close contact with an inner surface of the front end pipe 130 such that air may smoothly pass through the suction pipe 100. However, the present disclosure is not limited thereto, and a stepped portion may be formed in the inside of the front end pipe 130 such that the insertion pipe 120 is inserted into the stepped portion of the front end pipe 130, and in this case, an inner diameter of the insertion pipe 120 may also be the same as an inner diameter of the front end pipe 130.

(35) Referring to FIG. 6B, the elliptical portion 122 of the insertion pipe 120 may have a shape in which the other end thereof is obliquely cut. The other end of the elliptical portion 122 may be in the 6-o'clock direction of FIG. 3. Accordingly, the insertion pipe 120 may be easily inserted into the front end pipe 130, and an opening formed at the other end of the insertion pipe 120 may be formed to be larger such that foreign matter may be more smoothly sucked therein.

(36) In addition, referring to FIG. 6A, the elliptical portion 122 may include a cutout portion 123, which is formed by being cut in a predetermined length in the longitudinal direction of the insertion pipe 120, at one end of the obliquely cut portion. The one end may indicate the 12-o'clock direction of FIG. 3. In other words, as the cutout portion 123 is formed at the other end of the insertion pipe 120, the opening formed at the other end of the insertion pipe 120 may be more expanded, and thus, foreign matter may be more smoothly sucked, and when the insertion pipe 120 is inserted into the front end pipe 130, there is an effect that the other end of the insertion pipe 120 may be easily transformed.

(37) The above description of the present disclosure is for illustrative purposes only, and those skilled in the art related to the present disclosure will be able to understand that the present embodiments may be easily modified into other specific forms without changing the technical idea or essential features of the present disclosure. Therefore, it should be understood that the embodiments described above are illustrative and non-limiting in all respects. For example, each component described as a single type may also be implemented in a distributed manner, and similarly, components described in a distributed manner may also be implemented in a combined form.

(38) The scope of the present disclosure is indicated by the claims to be described below rather than the above detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalent concepts should be construed as being included in the scope of the present disclosure.
