DETAILED DESCRIPTION

[0023] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0024] like Figure 1-Figure 6As shown, the vacuum cleaner handle with tight connection and dust leakage prevention provided in this embodiment includes a connecting part 1 and a hand-held part 2, the connecting part 1 includes an inner tube 3, a sealing strip 4 is arranged on the outer side of the inner tube 3, an outer connecting tube 5 is arranged on the outer side of the inner tube 3, a groove 6 is formed between the outer connecting tube 5 and the inner tube 3, and a sealing ring 7 is arranged at the bottom of the groove 6. When connecting, the dust suction tube 10 is inserted into the groove 6. During the insertion process, the sealing strip 4 is squeezed and tightly attached to the inner wall of the dust suction tube 10 to form a first seal. When the dust suction tube 10 is inserted to the bottom, the sealing ring 7 will be squeezed to form a second seal, which greatly reduces the escape of dust and small particles during the vacuuming process and maintains a clean working environment.

[0025] In this embodiment, if Figure 1 As shown, the inner tube 3 is a hollow frustum structure that is small outside and large inside, and the cross section of the sealing strip 4 is triangular, which can form an effective seal between the inner tube 3 and the dust suction tube 10 to prevent dust from passing through and improve the sealing effect.

[0026] In this embodiment, if Figure 1 As shown, four sealing strips 4 are provided, and the four sealing strips 4 are evenly distributed on the inner insert tube 3 and along the circumference thereof, so as to further improve the sealing and connection effects.

[0027] In this embodiment, if Figure 1 As shown, a first thread 8 is provided on the outer side of the external connecting tube 5, and a fixed threaded tube 9 is connected to the outer side of the external connecting tube 5 through the first thread 8. A dust suction tube 10 is inserted into the groove 6, and a ring platform 11 is provided on the outer side of the dust suction tube 10. A second thread 12 is provided on the outer side of the ring platform 11. The external connecting tube 5 and the dust suction tube 10 are fixed by the fixed threaded tube 9 to ensure a stable connection.

[0028] In this embodiment, if Figure 1 As shown, the outer diameter of the ring platform 11 is the same as the outer diameter of the external connecting pipe 5, which ensures the alignment and concentricity during connection, reduces the difficulty of installation, and improves the connection effect.

[0029] In this embodiment, if Figure 1 and Figure 6 As shown, the connecting part 1 also includes an inner connecting tube 13, a third thread 14 is arranged on the outer side of the inner connecting tube 13, a thread groove 15 is arranged on the top of the inner insert tube 3, the inner insert tube 3 and the inner connecting tube 13 are connected by threads, and the sealing strip 4 may cause wear during the insertion and removal process. The inner insert tube 3 can be removed and replaced with a new inner insert tube 3 with a sealing strip 4.

[0030] In this embodiment, if Figure 1 As shown, a grip 16 is provided on the outer side of the handheld portion 2 to improve the comfort and holding stability during use.

[0031] In summary, in this embodiment, the vacuum cleaner handle provided in this embodiment adopts two sealing measures, the first one is a sealing strip 4 arranged on the outside of the inner tube 3, and the second one is a sealing ring 7 at the bottom of the groove 6 between the inner tube 3 and the outer connecting tube 5. These two sealing protections cooperate with each other to effectively form a tight dustproof interface, greatly reducing the escape of dust and small particles during the vacuuming process and maintaining a clean working environment. At the same time, the outer connecting tube 5 and the vacuum tube 10 are connected by fixing the threaded tube 9, so that a firm connection between the handle and the vacuum tube 10 is achieved. This threaded connection method is not only convenient for assembly and disassembly, but also provides additional structural stability to prevent dust leakage due to loose pipes during the vacuuming process.
