Detailed implementation mode

[0027] To better illustrate and elaborate on the content of the present utility model, the following will be described in conjunction with the accompanying drawings and implementation examples:

[0028] There is Figures 1 - 10 As shown, the present utility model discloses a disassembly structure for the air duct of a backpack hair dryer, including a first pipe body 1, a second pipe body 2, and a third pipe body 3. One end of the first pipe body 1 is inserted into the second pipe body 2 and locked and unlocked through a switch 4, and the other end of the second pipe body 2 is inserted into the third pipe body 3 and locked and unlocked through the switch 4.

[0029] Furthermore, a first installation groove 31 for installing the switch 4 is provided on the outside of the third pipe body 3, a first spring abutting portion 32 is provided in the first installation groove 31, and a first clamping groove 33 and a first locking groove 34 are provided inside the third pipe body 3.

[0030] Furthermore, a first clamping block 22 and a first mating convex block 21 are provided at one end of the second pipe body 2 that cooperates with the third pipe body 3. The first clamping block 22 can be inserted into the first locking groove 34, and the first mating convex block 21 can be inserted into the first clamping groove 33.

[0031] Furthermore, the switch 4 includes a locking portion 41, a rotating portion 42, and a spring portion 43. One switch 4 is installed in the first installation groove 31 through the rotating portion 42. A first compression spring (not shown) is provided between the spring portion 43 of the switch 4 installed in the first installation groove 31 and the first spring abutting portion 32, and the first compression spring drives the locking portion 41 to clamp the first clamping block 22.

[0032] Furthermore, a second installation groove 23 for installing the switch 4 is also provided on the second pipe body 2. A second spring abutting portion 24 is provided in the second installation groove 23, and a second clamping groove 25 and a second locking groove 26 are provided inside the second pipe body 2.

[0033] Furthermore, a plurality of second clamping blocks 11 and second matching protrusions 12 are provided at one end of the first tube body 1 that matches with the second tube body 2 . The second matching protrusion 12 can be inserted into the second clamping groove 25 , and the second clamping block 11 can be inserted into the second locking groove 26 .

[0034] Furthermore, another switch 4 is installed in the second mounting groove 23 through the rotating portion 42, and a second compression spring (not shown) is arranged between the spring portion 43 of the switch 4 in the second mounting groove 23 and the second spring abutment portion 24, and the second compression spring drives the locking portion 41 to clamp the second clamping block 11.

[0035] Specifically, during installation, the first tube body 1 is inserted into the second tube body 2, so that the second matching protrusion 12 is inserted into the second clamping groove 25, and the second clamping block 11 is inserted into the second locking groove 26. At the same time, the locking portion 41 of the switch 4 is close to the second clamping block 11 under the elastic force of the second compression spring and is clamped by the second clamping block 11.
