Description

Technical Field

[0001] This utility model relates to the field of hair dryer inner shell technology, specifically to a straight-tube integrated hair dryer inner shell assembly structure. Background Technology

[0002] Hair dryers, as a common personal care appliance, are widely used in daily life. Their basic principle is to use a motor to drive a fan, generating airflow. This airflow is heated by heating wires and then blown out of the nozzle, thus quickly drying the hair. As consumers' demands for hair dryer design, performance, and safety continue to rise, straight-tube integrated hair dryers, due to their compact structure, simple appearance, and smooth airflow, have gradually become the mainstream product in the market.

[0003] In the structural design of a straight-tube hair dryer, the inner shell, as the core load-bearing and functional integration component, undertakes the installation and positioning functions of key components such as the motor, heating element, and air duct system. Traditional hair dryer inner shells mostly adopt a split structure, assembled by splicing multiple independent parts. Among them, the heating element is usually installed on the inner shell using a connection method of blocks and slots to support the frame, which has poor stability, or it is fixed with bolts, making disassembly cumbersome.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a straight-tube integrated hair dryer inner shell assembly structure to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A cylindrical integrated hair dryer inner shell assembly structure includes an inner shell cylinder with a motor slot in the middle. The motor slot is connected to the inner shell cylinder via a connecting plate. One end of the motor slot is connected to a snap-fit ​​groove. There are six snap-fit ​​grooves, which match snap-fit ​​blocks. The snap-fit ​​blocks are connected to a support frame. Two of the snap-fit ​​blocks have grooves on both sides, and telescopic springs are installed inside the grooves. One end of the telescopic spring is connected to the snap-fit ​​block, and the other end is connected to a snap-fit ​​post.

[0008] Furthermore, the snap-fit ​​groove is provided with a snap-fit ​​slot, and the snap-fit ​​post matches the snap-fit ​​slot.

[0009] Furthermore, an electric heating wire is wound and fixed on the support frame.

[0010] Furthermore, a drive motor is installed inside the motor slot, and mounting blocks are provided on both sides of the drive motor. The motor slot is also provided with a mounting groove, and the mounting blocks match the mounting groove.

[0011] Furthermore, the mounting block is connected to the motor slot using bolts.

[0012] Furthermore, the output of the drive motor is connected to the fan.

[0013] Furthermore, a baffle is connected to the outer side of the inner shell.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) By setting six snap-fit ​​grooves on the inner shell and cooperating with the snap-fit ​​blocks on the support frame, a multi-point positioning structure is formed to ensure accurate alignment and circumferential stability during the installation of the heating component. Furthermore, two of the snap-fit ​​blocks have a linkage structure between a telescopic spring and a snap-fit ​​post within their grooves, which, in conjunction with the snap-fit ​​grooves on the inner shell, achieves a flexible snap-fit ​​connection. This design not only facilitates the rapid assembly and disassembly of the heating component but also allows for stress compensation through the extension and contraction of the springs under thermal expansion and contraction conditions, effectively preventing loosening or breakage caused by high-temperature deformation, thus improving connection reliability and service life.

[0016] (2) The drive motor is embedded in the mounting slot in the motor slot through the mounting blocks on both sides, and is further tightened with bolts to ensure the structural stability of the motor under high speed operation and reduce vibration and noise. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] According to an embodiment of the present invention, a straight-tube integrated hair dryer inner shell assembly structure is provided.

[0027] Example 1

[0028] like Figures 1-5 As shown, the straight-tube integrated hair dryer inner shell assembly structure according to an embodiment of this utility model includes an inner shell cylinder 1. The inner shell cylinder 1 has good electrical insulation performance and thermal stability, and can effectively withstand the structural stress and thermal deformation of the hair dryer under long-term high-temperature operation. A motor slot 2 is provided in the middle of the inner shell cylinder 1. The outer side of the motor slot 2 is connected to the inner shell cylinder 1 through a connecting plate 3. The connecting plate 3 not only plays a structural support role, but also has the functions of guiding airflow and reducing weight. It can optimize the airflow direction of the internal air duct, reduce wind resistance, and improve the air volume output efficiency while ensuring the overall structural strength. The motor slot 2... One end is connected to a snap-fit ​​groove 4, and there are six snap-fit ​​grooves 4. The snap-fit ​​grooves 4 match the snap-fit ​​blocks 5. The snap-fit ​​blocks 5 are connected to the support frame 6. The support frame 6 is wound and fixed with an electric heating wire 11. Two of the snap-fit ​​blocks 5 have grooves 7 on both sides. The grooves 7 have telescopic springs 8 inside. One end of the telescopic spring 8 is connected to the snap-fit ​​block 5, and the other end is connected to the snap-fit ​​post 9. The snap-fit ​​groove 4 has a snap-fit ​​slot 10. The snap-fit ​​post 9 matches the snap-fit ​​slot 10. When the support frame 6 is installed in place, the snap-fit ​​post 9 automatically pops out under the action of the spring force and is embedded in the snap-fit ​​slot 10 in the snap-fit ​​groove 4 to achieve self-locking fastening.

[0029] like Figures 1-4As shown, a drive motor 12 is installed inside the motor slot 2. Mounting blocks 13 are located on both sides of the drive motor 12. An mounting groove 14 is located inside the motor slot 2. The mounting blocks 13 match the mounting groove 14, and are connected to the motor slot 2 by bolts. The mounting blocks 13 can slide into or embed into the mounting groove 14 for initial positioning. Subsequently, the mounting blocks 13 are locked to the motor slot 2 with bolts, forming a secure mechanical connection. This ensures that the motor will not shift or vibrate during high-speed rotation, improving operational stability. A baffle 16 is connected to the outer side of the inner shell 1. The baffle 16 abuts against the fixed plate inside the hair dryer outer shell, forming an axial limit to prevent the inner shell from moving back and forth during assembly or use. Simultaneously, the baffle 16 has bolt holes, allowing it to be connected to the outer shell fixed plate via bolts, achieving reliable locking between the inner and outer shells.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] In summary, with the help of the above-mentioned technical solution of this utility model, in actual use, the drive motor 12 is first inserted axially from one side of the motor slot 2, so that the mounting blocks 13 on both sides slide accurately into the preset mounting slots 14 in the motor slot 2, achieving rapid positioning. This sliding design facilitates automated assembly and improves production efficiency. Subsequently, by screwing bolts into the through holes on the mounting blocks 13, the drive motor 12 is firmly locked in the motor slot 2, ensuring that the motor remains stable even when running at high speed (usually the speed can reach tens of thousands of revolutions per minute), effectively suppressing vibration and noise, and improving the smoothness and service life of the whole machine. Next, the support frame 6 with the electric heating wire 11 wound around it is aligned with the six snap-fit ​​slots 4 at the front end of the inner shell cylinder 1 and pushed in radially or axially. When the support frame 6 reaches the predetermined installation position, the telescopic springs 8 located in the grooves 7 of two of the symmetrical snap-fit ​​blocks 5 push the snap-fit ​​posts 9 outward due to the release of constraints, so that the snap-fit ​​posts 9 quickly embed into the corresponding snap-fit ​​slots 10 on the side wall of the snap-fit ​​slot 4, achieving automatic locking. This flexible snap-fit ​​structure not only ensures the circumferential fixation and axial anti-detachment of the heating component, but also has a certain buffering capacity, improving the long-term reliability of the heating system. After the installation of the motor and heating component is completed, the entire inner shell structure is basically integrated. At this time, the assembled inner shell cylinder 1 is placed into the outer cylinder of the hair dryer, so that the baffle 16 on the outside of the inner shell cylinder 1 abuts against the fixing plate on the inner wall of the outer shell, forming an axial limit to prevent the inner shell from moving back and forth during subsequent use. Finally, the baffle 16 is locked to the outer shell fixing plate through the bolt holes on the baffle 16, realizing a rigid connection between the inner shell and the outer shell, ensuring that the whole machine structure is compact, well-sealed, and avoids air leakage and abnormal noise.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
