At this time, the power tail line 5 is restricted by the inner fixing part 2, so that the power tail line 5 is assembled in the inner fixing part 2; then the elastic clamping part 3 is assembled to the inner fixing part 2 and part of the protruding part is placed in the anti-slip groove 21; finally, the outer fixing part 1 is sleeved on the surface of the inner fixing part 2. At this time, the extended clamping plate 11 of the outer fixing part 1 moves along the anti-slip groove 21 until it is resisted by the clamping piece 32 of the elastic clamping part 3, so that the outer fixing part 1 is indirectly fixed to the inner fixing part 2. The overall structure is simple. When the air inlet cover needs to be replaced, it only needs to be pulled out with force, which is easy to assemble and produce.

[0033] like Figure 5 As shown, the inner fixing portion 2 includes a left locking block 22 and a right locking block 23 of the same structure, the right locking block 23 is provided with a right arc-shaped platform 231 and a right stop groove 232, the left locking block 22 is provided with a left arc-shaped platform (not shown in the figure) symmetrically arranged with the right arc-shaped platform 231 and a left stop groove (not shown in the figure) symmetrically arranged with the right stop groove 232, and the power positioning end 4 is provided with a stop block 41 and an arc-shaped block 42. When the power positioning end 4 is assembled with the left locking block 22 and the right locking block 23, the left arc-shaped platform (not shown in the figure) and the right arc-shaped platform 231 are combined to limit the arc-shaped block 42, thereby limiting the position of the power positioning end 4, and the stop blocks 41 at different positions are respectively inserted into the left stop groove (not shown in the figure) and the right stop groove 232 to prevent the power positioning end 4 from rotating on the left arc-shaped platform (not shown in the figure) and the right arc-shaped platform 231.

When the power connection end 51 is assembled with the left locking block 22 and the right locking block 23, the connecting transverse card block 52 is inserted into the left transverse card groove 221 and the right transverse card groove 233, thereby realizing the fixation of the power connection end 51 by the internal fixing part 2.

[0035] like Figure 1 As shown, a hair dryer body 6 is provided on one side of the inner fixing portion 2. Figure 5 , Figure 6 and Figure 7 As shown, a support plate 61 is provided on the tail of the hair dryer body 6, and a plate supporting card hole 62 is provided on the support plate 61, a left supporting card hole 222 and a positioning bolt 223 are provided on the left locking block 22, and a right supporting card hole 234 corresponding to the position of the left supporting card hole 222 is provided on the right locking block 23. It should be noted that when the inner fixing part 2, the power positioning end 4 and the power tail line 5 are assembled, the left locking block 22 and the support plate 61 can be fixed by inserting the positioning bolt 223 into the left supporting card hole 222, and then the power positioning end 4 and the power tail line 5 are inserted into the corresponding position of the left locking block 22 fixed on the support plate 61, and finally the right locking block 23 is aligned with the left locking block 22, and the right supporting card hole 234 corresponds to the plate supporting card hole 62, and the positioning bolt 223 is further screwed into the right supporting card hole 234 to realize the assembly of the power tail line 5 and the inner fixing part 2 by the left locking block 22 and the right locking block 23;

[0036] The power connection end 51 of the power tail line 5 can also be inserted into the power positioning end 4 first, and then the left locking block 22 and the right locking block 23 are brought close to each other, and the power positioning end 4 and the power connection end 51 of the power tail line 5 are wrapped and fixed together, and then moved together to the support plate 61. At this time, the left support card hole 222, the plate support card hole 62 and the right support card hole 234 are located on the same horizontal line, and the positioning bolt 223 is directly inserted into them from the left or right side until the positioning bolt 223 is simultaneously located in the left support card hole 222, the plate support card hole 62 and the right support card hole 234. At this time, the left locking block 22 and the right locking block 23 assemble the power tail line 5 with the internal fixing part 2.

[0037] like Figure 7-10 As shown, the left locking block 22 and the right locking block 23 in this embodiment have the same structure. The structure is explained by taking the left locking block 22 as an example. The placement position on the left locking block 22 is a placement through hole 24, and the elastic member 31 and the clamping member 32 are placed in the placement through hole 24; an extended retaining wall 241 (such as a retaining wall 241 protruding in the direction of the central axis L) is provided on one side of the placement through hole 24 close to the anti-slip groove 21. Fig.10 As shown in the figure, the extended retaining wall 241 blocks the clamping member 32 and restricts its movement toward the anti-slip groove 21; a clamping hole 242 is provided on the extended retaining wall 241, through which the clamping member 32 can partially protrude and connect the placement through hole 24 with the anti-slip groove 21. The clamping member 32 partially extends into the anti-slip groove 21 through the clamping hole 242 to restrict the extended clamping plate 11.

[0038] Specifically, an inner frame 7 and an inner cover 71 are sleeved on the outer periphery of the support plate 61, a frame slot 224 is provided on the left locking block 22 at the outer side of the placement through hole 24, a plurality of vertical long plates 72 are provided on the inner frame 7, a bottom fixing hole 73 and a bottom bolt 74 are provided at the bottom of the inner frame 7, and a bottom fixing hole 225 corresponding to the position of the bottom fixing hole 73 is provided at the bottom of the left locking block 22; during assembly, the inner cover 71 is sleeved on the outer periphery of the inner frame 7, and then the inner frame 7 with the inner cover 71 is sleeved on the outer peripheral surface of the extended clamping plate 11, at this time, the vertical long plate 72 is stuck in the frame slot 224 to block the elastic member 31, so that the elastic member 31 and the clamping member 32 are located in the placement through hole 24 and will not fall off, and then the bottom bolt 74 is stuck in the bottom fixing hole 1 73 and the bottom fixing hole 225 to achieve the fixation of the inner frame 7 and the support plate 61, and this process realizes the assembly of the elastic clamping portion 3, the inner frame 7 and the inner cover 71.

[0039] Specifically, the outer fixing part 1 is an air inlet cover, and the air inlet cover is provided with a plurality of air inlet holes (not marked in the drawings) for letting air into the hair dryer body 6, and at the same time ensuring that foreign dust from the outside does not enter the hair dryer, the extension card plate 11 of the air inlet cover is provided with an anti-slip boss 12, and a clearance position 75 for the extension card plate 11 to pass through and move to the anti-slip groove 21 is provided at the bottom of the inner frame 7; during assembly, the air inlet cover is sleeved on the outer periphery of the inner frame 7 and the inner cover 71, The extended card plate 11 passes through the avoidance position 75 and enters the anti-slip groove 21, and the anti-slip boss 12 of the extended card plate 11 first presses upward against the clamping piece 32, so that the clamping piece 32 moves into the accommodation through hole 24 until the lower end surface of the anti-slip boss 12 exceeds the clamping piece 32. At this time, the clamping piece 32 moves to the empty space below the anti-slip boss 12 under the elastic action of the elastic piece 31 until the clamping piece 32 presses against the lower end of the anti-slip boss 12. In this process, the clamping piece 32 restricts and fixes the extended card plate 11.

[0040] The anti-detachment device of the utility model has a simple structure. When the inner cover needs to be cleaned, the air inlet cover can be exposed for cleaning by simply pulling it out with force. It is easy to assemble and produce. If other parts need to be replaced, such as the elastic part 31, the clamping part 32, etc., the bottom bolt and the positioning bolt 223 can be unscrewed in turn after the air inlet cover is detached, which is convenient for disassembly.
