[0058] Please refer to Figure 1-21 ,

[0059] like Figure 1 As shown, the utility model provides a connection structure between a hair dryer body and a handle, comprising an integrally formed tubular body shell 1 with two ends open, an intermediate connecting piece, and an integrally formed tubular handle shell 3 with two ends open, characterized in that: the body shell 1 can accommodate an inner cylinder 4, the handle shell 3 can accommodate a handle inner shell 5, a hole 11 penetrating the side wall of the body shell 1 is provided, the body shell 1 is integrally formed as a whole into a tubular shape with two ends open, the intermediate connecting piece can be placed in the body shell 1, the intermediate connecting piece can be attached to the inner wall of the body shell 1, and the intermediate connecting piece cannot be completely passed through and fall off from the hole 11 in the body shell 1. The intermediate connecting piece is a connecting component, which is in the shape of a ring or a hollow mushroom and has an overall size larger than the aperture of the hole 11, and is at least partially or completely arranged inside the body shell 1, and cannot be completely passed through and fall off from the hole 11 in the body shell 1, otherwise it cannot play a connecting role. By setting a hole 11 on the side wall of the main body shell 1, and there is no other protrusion on the side wall that is higher than the side wall surface, this structural design is simple, which greatly reduces the design difficulty of the mold of the main body shell 1. It only needs to add a row of hole 11 to the front mold and the rear mold, which can save the mold production cost and ensure that there will be no mold line on the side wall of the main body shell 1, ensuring the overall smoothness and beauty of the side wall surface of the main body shell 1. The structure of the intermediate connecting piece reduces the complexity of the injection molding or cutting and engraving processing of the main body shell 1. The intermediate connecting piece plays the role of connecting the main body shell 1 with the handle inner shell 3. The intermediate connecting piece in the utility model has a variety of different forms and installation methods. The utility model embodiment only illustrates three examples, which are named "intermediate connecting piece 1 7", "intermediate connecting piece 2 8" and "intermediate connecting piece 3 9" respectively.

[0060] like Figure 2 As shown, Figure 2This is a quarter cross-sectional view of the utility model. The intermediate connector is an intermediate connector 7. The intermediate connector 7 includes a fixing seat 71 and a limiting annular surface 72 provided below the fixing seat 71 to limit the position of the matching hole 11. The main body shell 1 and the inner tube 4 can clamp the fixing seat 71. The intermediate connector 7 is divided into two parts: the fixing seat 71 and the limiting annular surface 72. The fixing seat 71 is used to limit the intermediate connector 7 inside the main body shell 1 to prevent it from falling out. The limiting annular surface 71 is used to limit the position of the intermediate connector 7 in the main body shell 1 to prevent the intermediate connector 7 from sliding. The inner tube 4 is used to prevent the limiting annular surface 72 from falling out of the hole 11, that is, the main body shell 1, the inner tube 4 and the intermediate connector 7 can be mutually limited and fixed as a whole.

[0061] like Figure 3 As shown, a connecting portion 73 is provided below the limiting ring surface 72, and the connecting portion 73 protrudes out of the outer surface of the side wall of the main body shell 1 to the outside of the hole 11. The connecting portion 73 is provided with a second hole 731, and a cross 74 is provided on the handle inner shell 5. The second hole 731 can be passed through by the cross 74. Fig.17 As shown, the two half-molded handle inner shells 5 are clamped and fixedly connected to the connecting portion 1 73. The cross 74 plays the role of a latch here. In order to strengthen the connection effect, the cross 74 axis center is also provided with a hole 3 51, and a bolt fastener is inserted in the hole 3 51 to strengthen the connection.

[0062] like Figure 4 , Fig.16 As shown, Figure 2 This is a quarter cross-sectional view of the utility model. The outer surface of the connecting part 73 is provided with a groove 211 that is recessed inward, and the handle inner shell 5 is provided with a protrusion 212 near the inner diameter of the top. The groove 211 and the protrusion 212 can be engaged with each other. In addition to using the cross 74 as a latch, there is another connection scheme. By clamping the groove 211 of the connecting part 21 with the protrusion 212, the handle inner shell 5 can be prevented from being separated from the connecting part 21, which plays a fixing role. The groove 211 and the protrusion 212 in this embodiment include a method of replacing the groove 211 with an internal thread and replacing the protrusion 212 with a screw thread.

[0063] like Figure 5As shown, there is a gap between the connection part 173 and the hole 11, and the height a of the limiting annular surface 172 is less than the wall thickness b of the main body shell 1, and a wall surface 75 that does not touch the limiting annular surface 172 and does not touch the outer surface of the handle inner shell 5 can be formed at the hole 11, and the handle inner shell 5 and the handle outer shell 3 can be clamped between the wall surface 75 and the connection part 173. The limiting annular surface 172 does not completely cover the hole 11, and a part of the wall surface 75 that is not blocked is left at the bottom of the hole 11. The wall surface 75 can form an annular groove with the connection part 173, and this annular groove can clamp the handle inner shell 5 and the handle outer shell 3, thereby strengthening the stability of the connection structure.

[0064] like Fig.15 As shown, the middle connecting piece 7 is in the shape of a mushroom tube as a whole, and is hollow inside to form a through hole 732, which can be used to pass electrical components and circuits, and can also be used for ventilation and diversion.

[0065] like Figure 6 , Fig.18 and Fig.19 As shown, the intermediate connecting member is the intermediate connecting member 2 8, and the intermediate connecting member 2 8 includes a fixing seat 2 81, a connecting portion 2 82 protruding from the hole 11 below the fixing seat 2 81, and the fixing seat 2 81 is provided with a hole 4 112, and a symmetrically distributed extension block extends from the hole 11 of the side wall of the body shell 1 to the center of the hole circle, and a circle inner hole 63 is opened on the extension block, and the intermediate connecting member 2 8 is fixed to the body shell 1 through the hole 4 112 and the circle inner hole 63. By setting the hole 4 112 above the fixing seat 2 81, the hole 4 112 is a threaded hole, and the circle inner hole 63 corresponding to the hole 4 112 is opened on the body shell 1, the intermediate connecting member 2 8 can be more firmly installed on the body shell 1.

[0066] like Fig.19 As shown, the middle connecting member 2 8 is in the shape of a mushroom tube as a whole, and is hollow inside to form a through hole 2 83, which can be used to pass electrical components and circuits, and can also be used for ventilation and diversion.

[0067] like Figure 7 As shown, a pressing block 25 is provided under the main body shell 1, and the pressing block 25 and the second fixing seat 81 can squeeze and fix the main body shell 1. By fastening the pressing block 25 and the second fixing seat 81, the main body shell 1 can be clamped, and the fastening connection method in this embodiment can be a buckle clamping and locking screws.

[0068] like Figure 8 , Fig. 20 and Fig.21As shown, the intermediate connector is intermediate connector three 9, and the intermediate connector three 9 is arranged inside the main body shell 1. The handle inner shell 5 is a semi-open structure. A hole five 61 is arranged around the hole one 11, and the hole five 61 is connected with the hole one 11, which can allow errors during assembly and reduce the area occupied by the hole five 61 to help reduce the overall diameter of the handle. Of course, when there is enough space, a plurality of independent outer circle holes 62 that are not connected with the hole one 11 can be evenly arranged around the hole one 11. A flange 66 is radially extended inward from the top end of the handle inner shell 5, and an inner shell connecting hole 661 is arranged on the flange 66, which can be fixed to the intermediate connector three 9 through the hole five 61 or the outer circle hole 62. An inwardly protruding flange 66 is provided at the top of the handle inner shell 5, where the flange 66 acts as a flange. A hole 5 61 is provided around the hole 11, and the hole 5 61 is a wall-breaking hole. The flange 66 can be fastened to the intermediate connecting piece 3 9 through the hole 5 61 to clamp the main body outer shell 1. The reason why the handle inner shell 5 is a semi-open structure is to facilitate the locking of screws.

[0069] like Fig.21 As shown, the intermediate connecting member 3 9 is annular as a whole, and is hollow inside to form a through hole 3 91, which can be used to pass electrical components and circuits, and can also be used for fluid to pass through; the inner shell connection clamping hole 92 on the intermediate connecting member 3 9 corresponding to the hole 5 61 or the outer hole 62 of the ring is provided for fastener connection.

[0070] like Fig. 20 As shown, when a plurality of independent outer holes 62 not connected to the hole 11 are evenly arranged around the hole 11, the outer holes 62 can be set as threaded holes, and bolt fasteners are passed through the inner shell connecting holes 661 to directly thread the outer holes 62, thereby realizing the direct connection between the handle inner shell 5 and the main body outer shell 1. This structure does not require the cooperation of the intermediate connecting member three 9. Of course, for the firmness of the structure, it is more reliable for the intermediate connecting member three 9 to clamp and cooperate with the structure from the inside of the main body outer shell 1. It should be noted that the plurality of inner shell connecting holes 661 or the plurality of holes five 61 are distributed around the hole 11. Compared with the inner circle holes 63 distributed in the hole 11, the blockage of the liquid passing through the hole 11 can be reduced, and the passing space of the components and circuits in the hole 11 can be increased.

[0071] like Fig. 9 As shown, the tail end of the handle outer shell 3 is provided with a protrusion 692 extending inward, and the handle inner shell 5 is provided with a protrusion 691 extending inward near the tail end. The protrusion 691 can be connected to the protrusion 692, and both can be provided with perforations for fastening with fasteners to prevent the handle outer shell 3 from falling off. The protrusion 691 and the protrusion 692 are locked with each other to prevent the handle outer shell 3 from falling off from the handle inner shell 5. The locking method in this embodiment can be snap, glue or screw locking.

[0072] like Fig.10 , Fig.21 As shown, a groove 2 113 is provided around the hole 11, and a handle shell block hole 64 is provided at the bottom of the groove 2 113. The top of the handle shell 3 is inserted into the groove 2 113, and a handle shell block 31 is provided at the top of the handle shell 3, and the handle shell block 31 is inserted into the handle shell block hole 64; by inserting the handle shell 3 into the groove 2 113, the top of the handle and the outer surface of the body can be adapted to be connected, thereby increasing the appearance after the connection; by inserting the handle shell block 31 into the handle shell block hole 64 structure, the stability of the overall structure can be enhanced; in addition to the hole 11, the hole 5 61 or the outer hole 62, the side wall of the body shell 1 is additionally provided with a groove 2 113 and a handle shell block hole 64. If a metal pipe processing method is adopted, in addition to cutting and drilling, engraving is also required, or a mold position demoulding method is adopted. Although the processing cost will increase, it is still a better way to achieve a smooth overall appearance of the body shell 1 and the product after assembly.
