[0042] Please refer to Figure 1-9 ,

[0043] like Figure 1 As shown, the utility model provides a connection structure between a hair dryer body and a handle, comprising a hair dryer shell 1, a handle shell 2, and a connector 3, characterized in that a recessed groove 4 is provided on the outer surface of the hair dryer shell 1, a convex block 41 is provided in the recessed groove 4, and the height of the convex block 41 does not exceed the surface of the hair dryer shell 1. The recessed groove 4 can make the product appearance surface smooth and free of parting lines when the hair dryer shell 1 is integrally formed, and the height of the convex block 41 in the recessed groove 4 does not exceed the surface of the hair dryer shell 1, so that the hair dryer shell 1 can be easily removed from the mold, and the internal features of the recessed groove 4 can be processed by a small position, and the small size of the position means that the volume of the entire mold is small, which can save the mold production cost and can also produce multiple batches of molds at one time. The manufacturing method of the wind duct shell 1 in this embodiment requires a fixed mold, and multiple movable molds can be inserted into the fixed mold. The movable mold is used to make the inner cavity of the wind duct shell 1, and the fixed mold is used to make the outer cavity of the wind duct shell 1. Because the surface of the outer cavity is smooth, the movable mold can bring the wind duct shell out of the fixed mold. In the fixed mold, each movable mold position is provided with a slide position on the side, and the slide position is used to make the connection part feature of the wind duct shell 1, that is, the recessed groove 4. Since the height of the connection part feature, the protrusion, that is, the convex block 41, does not exceed the surface of the wind duct shell 1, it will not affect the structure of the wind duct shell 1 when it is removed after injection molding, and it also has the advantage of hiding the joining line.

[0044] like Figure 2 As shown, the top of the connector 3 is provided with a connecting wall 31 and a connecting surface 32, the connecting wall 31 can fit the groove wall 44 of the concave groove 4, and the connecting surface 32 can fit the bottom surface 45 of the concave groove 4. The design of the connecting wall 31 and the connecting surface 32 can make the connection between the connector 3 and the air duct housing 1 smooth and have a curved surface, which can enhance the high-end brand image of the product and increase the user experience.

[0045] like Figure 3As shown, the recessed groove 4 is provided with a positioning hole 42, and the connecting member 3 includes a positioning block 33 corresponding to the positioning hole 42. The protrusion 41 is provided with a hole 1 411, and the connecting member 3 includes a groove 34 corresponding to the protrusion 41, and a hole 2 35 corresponding to the hole 1 411 is provided in the groove 34. The hole 1 411 is a threaded hole, and a screw fastener can pass through the hole 2 35 and be threadedly connected to the hole 1 411.

[0046] ① Through the cooperation between the positioning hole 42 and the positioning block 33, the connecting member 3 can be prevented from shaking on the air duct housing 1.

[0047] ② Through the cooperation between the protrusion 41 and the groove 34, the connecting member 3 can be prevented from shaking on the air duct housing 1.

[0048] ③ By the cooperation between the positioning hole 42 and the positioning block 33 and the cooperation between the protrusion 41 and the groove 34, the connecting part 3 can be prevented from shaking on the wind duct housing 1; by the screw fastener passing through the hole 2 35 and being threadedly connected to the hole 1 411, the connecting part 3 can be fixed on the wind duct housing 1.

[0049] like Figure 4 As shown, the recessed groove 4 is further provided with a harness hole 43, and a wire passing seal 431 is sleeved on the harness hole 43. The wire passing seal 431 can be made of a soft and elastic rubber material, and the wire passing seal 431 sleeved on the harness hole 43 can protect the line from being cut, causing safety hazards, and can also play a certain sealing role.

[0050] like Figure 5 As shown, the handle housing 2 contains an inner support member 5, and a step 56 is provided inside the inner support member 5, and the step 56 can support the bottom of the connecting member 3. The step 56 supports the bottom of the connecting member 3 to prevent the connecting member 3 from sliding down.

[0051] like Figure 6 As shown, Figure 6 The inner support member 5 is in a disassembled state. Figure 6The dotted line in the figure is the disassembly guide line of the inner support member 5. The lower part of the connecting member 3 is a clamping end 36. A hole three 361 and a hole four 362 are provided in the middle of the clamping end 36. The hole three 361 and the hole four 362 are coaxially designed to face each other at both ends of the clamping end. The inner support member 5 includes a shell 1 51 and a shell 2 52. The shell 1 51 and the shell 2 52 can hold the clamping end 36. The inner wall of the shell 1 51 is provided with a column 1 511, and the two ends of the column 1 511 are respectively provided with countersunk holes 571; the inner wall of the shell 2 52 is provided with a column 2 521, and the column 2 521 is provided with a threaded hole 572. The column 2 521 can be inserted into the countersunk hole of the column 1 511. The hole three 361 can be nested in the column 1 511, and the hole four 362 can be nested in the column 2 521. Pass the column 1 511 on the shell 1 51 through the hole 361 of the connecting member 3, and then pass the column 2 521 on the shell 2 52 through the hole 4 362 of the connecting member 3, insert the screw 573 into the column 1 511, and lock the screw 573 into the threaded hole in the column 2 521. At this time, the shell 1 51 and the shell 2 52 clamp the clamping end 36, so that the shell 1 51, the shell 2 52 and the connecting member 3 are fixedly connected to each other as a whole.

[0052] like Figure 6 , Figure 7 As shown, the connecting member 3 is provided with a groove 39 , and the housing 1 51 and the housing 2 52 are provided with protrusions 55 corresponding to the groove 39 one by one, and the protrusions 55 can be stuck in the groove 39 . After the connecting member 3 is fixed by the column 1 511 and the column 2 521, the connecting member 3 may still shake. By inserting the protrusion 55 on the shell into the groove 39 of the connecting member 3, the shaking of the connecting member 3 can be eliminated or slowed down. The groove 39 is long and narrow, symmetrically distributed on both sides of the hole 361 and the hole 4 362, and is connected to the hole 361 and the hole 4 362. After the connecting member 3 is connected to the inner support member 5, theoretically due to the assembly clearance, it may rotate and shake with the axis line of the hole 361 as the rotation axis. The groove 39 is long and narrow and symmetrically distributed on both sides of the hole 361 and the hole 4 362, and cooperates with the protrusion 55 which is also long and narrow, to form a large torque limit with the axis line of the hole 361 as the rotation axis, thereby eliminating or slowing down the shaking of the connecting member 3 relative to the inner support member 5 to a large extent.

[0053] like Figure 8 As shown, the connector 3 is provided with a connecting surface 37, and the top of the clamping end 36 of the connector 3 is provided with a second step 38, through which the handle housing 2 can be smoothly connected to the connecting surface 37, and the connecting surface 37 and the outer surface of the wind tube housing 1 are also smoothly transitioned. The second step 38 allows the handle housing 2 to transition flush with the table surface, improving the hand feel.

[0054] like Fig. 9As shown, the wind tube housing 1 contains a wind tube 11, and the wind tube 11 is detachably connected to the wind tube housing 1; the inner support 5 is provided with a main control component 53, and the main control component 53 is electrically connected to the wind tube 11; the handle housing 2 is provided with a switch component 54, and the switch component 54 is electrically connected to the main control component 53. The wind tube 11 is controlled by sending a command to the main control component 53 through the switch component 54.
