Whereby the first connector 41 can be mounted to the second connector 42. [

A groove 231 perpendicular to the extending direction of the coupling pipe 23 may be continuously formed on the outer surface of the coupling pipe 23. By forming the groove 231 continuously on the outer surface of the connection pipe 23, the connection pipe 23 can move more flexibly.

The first connector 41 may be formed with a fixed rib 412. The fixed ribs 412 may be formed on the inner surface of the first connector 41. The fixed rib 412 may be provided to be inserted into the groove 231 formed in the coupling pipe 23 when the first connector 41 is mounted on the second connector 42. [

In detail, the fixed ribs 412 may protrude so as to be perpendicular to the inner surface of the first connector 41. The shape of the end of the fixing rib 412 may correspond to the shape of the groove 231 formed on the outer surface of the coupling pipe 23.

The second connector 42 may be provided with a through-hole 423 through which the fixed rib 412 can pass. The rib through-hole 423 may be formed to correspond to the shape of the fixed rib 412.

Whereby the connection tube 23 can be interfered with by the fixed rib 412. [ The connection tube 23 is interfered by the fixed rib 412 and the fusion tube is applied between the connection tube 23 and the second connector 42 so that the connection tube 23 is fixed . The connection pipe 23 can be welded to the second connector 42 by the interference of the connection pipe 23 by the fixing rib 412. In this case, 42, respectively.

The second connector 42 may further include a fixing hole 424. The fixing hole 424 may be formed at a position where the connection pipe 23 of the second connector 42 is inserted. A plurality of fixing holes 424 may be formed.

When the connection pipe 23 is inserted into the second connector 42 and the fusion liquid is applied between the connection pipe 23 and the second connector 42, And can flow out of the second connector 42 through the fixing hole 424. [ The connection pipe 23 and the second connector 42 can be more stably connected and fixed by a wide fusion area when the fusion liquid flows out of the second connector 42 through the fixing hole 424 and solidifies. The joint pipe 23 and the second connector 42 connected to each other by the fusing liquid are more likely to flow out of the second connector 42 through the fixing hole 424 because the fusion liquid that solidifies out is interfered by the fixing hole 424 So that the sealing structure between the connecting pipe 23 and the second connector 42 can be easily realized.

A recessed portion 426 may be formed on the inner surface of the second connector 42. The concave / convex portion 426 may be provided with a pattern formed by corroding the inner surface of the second connector 42 or including convex portions and concave portions. The concave and convex portion 426 may be formed on the inner side surface of the second connector 42 into which the coupling tube 23 is inserted. The inner surface of the second connector 42 is corroded or a pattern is formed, so that the contact area of the fused liquid is widened, so that the fusing force can be improved. As a result, the connection tube 23 is connected to the second connector 42 and can be more stably fixed.

As described above, it is possible to prevent the interference of the connection tube 23 by the fixed rib 412, the structure in which the fusion liquid is filled in the hole 424, the structure in which the contact surface of the fusion liquid is increased by forming the corrosion surface or the pattern surface, The tube 23 can be connected to the connector 40 and stably fixed.

According to the above structure, when the vacuum cleaner 1 is used, it is possible to prevent the connector tube 23 from being broken or torn out from the connector 40 due to frequent folding or the like. The connection pipe 23 and the connector 40 are directly connected to each other without requiring a member or a sealing member for connecting the connection pipe 23 to the connector 40 so that the material cost can be reduced and the work flow can be reduced And the hole 424 of the second connector 42 is filled with the fusion liquid so as to improve the sealing force of the connection pipe 23 and the second connector 42 as well as to improve the sealing force. In addition, by widening the fusion area through the corroded surface or the surface on which the pattern is formed, the connection pipe 23 can be mounted on the connector 40 more stably.

Although the vacuum cleaner of the canister type has been described above, the connection structure between the connector and the connector is applicable to an upright type vacuum cleaner having a connection pipe.
