[0027] This specific embodiment is a concealed, reverse-opening hair dryer handle, as shown in the schematic diagram below. Figure 1-7 As shown, the device includes a first handle 1, a second handle 2 located at the center of the upper surface of the first handle 1, a reverse button 3 located on one side of the center of the upper surface of the second handle 2, a blower push block 4 located on one side of the reverse button 3 and on the upper surface of the second handle 2, a mounting structure 5 located on one side wall of the first handle 1 and the second handle 2, a protective structure 6 fitted on the inner side wall of both the first handle 1 and the second handle 2, a cable management structure 7 located on the inner side wall of both protective structures 6, and a mounting interface 8 fitted on one side of the center of the outer side wall of the first handle 1 and the second handle 2. Both the first handle 1 and the second handle 2 are semi-circular. The reverse button 3 and the blower push block 4 are designed to change the airflow direction, wind speed, or other blowing modes of the blower. When the reverse button 3 is pressed, the blower push block 4 is moved through the linkage mechanism, thereby changing the internal air duct structure of the blower and realizing the reverse blowing of the air.

[0028] First, in this embodiment, the specific structures of the two protective structures 6 are as follows:

[0029] The two protective structures 6 include a first inner layer 601, which is fitted onto the inner wall of the first handle 1, and a second inner layer 602, which is fitted onto the inner wall of the second handle 2. Three mounting blocks 603 are arranged in a ring on the outer walls of both the first and second inner layers 601 and 602. Mounting grooves 604 are fitted onto the inner walls of both the first and second handles 1 and 2. The six mounting blocks 603 are slidably connected to the center of the six mounting grooves 604. Both the six mounting blocks 603 and the six mounting grooves 604 are convex in shape. The convex shape of the mounting blocks 603 and the mounting grooves 604 facilitates the installation of the protective structure 6. While ensuring the stable connection of the protective structure 6 to the inner walls of the first and second handles 1 and 2, the mounting blocks 603 have a certain buffer sliding space within the mounting grooves 604 when the handles are subjected to slight impacts or vibrations, absorbing some of the impact force and protecting the internal structure. Furthermore, they are easy to disassemble and replace, facilitating maintenance.

[0030] Furthermore, the mounting structure 5 includes two grooves 509, which are respectively located at the center of the upper end face of the first handle 1 and the center of the lower end face of the second handle 2. An outer tube 501 is located at the center of the inner wall of the upper groove 509, and a compression spring 502 is located at the center of the inner wall of the outer tube 501. One end of the compression spring 502 is fixedly connected to an inner tube 503, which is slidably connected to the center of the inner wall of the outer tube 501. A retaining tube 504 is located at the center of the lower inner wall of the lower groove 509, and the inner tube 503 and the retaining tube 504 are mutually compatible. A threaded groove 506 is located on the other side of the center of the outer wall of the first handle 1 and the second handle 2, and a sleeve 505 is threaded onto the outer wall of the threaded groove 506. Multiple positioning blocks 507 are arranged laterally at the front and rear of the center of the upper end face of the first handle 1, and multiple positioning grooves 508 are arranged laterally at the front and rear of the center of the lower end face of the second handle 2, with the multiple positioning blocks 507 mutually compatible.

[0031] During installation, first align the positioning block 507 with the positioning groove 508 to initially determine the relative position and direction of the first handle 1 and the second handle 2. Then, the compression spring 502 in the upper groove 509 pushes the inner tube 503 into the lower clamping tube 504 to achieve positioning and elastic connection. This can buffer the external forces such as vibrations that the handles are subjected to during use to a certain extent. Then, by rotating the sleeve 505, it is tightened on the threaded groove 506 to further strengthen the connection between the two handles and ensure the stability of the entire handle structure, meeting the requirements of the handle structure strength of the hair dryer during operation. When disassembly and maintenance are required, simply rotate the sleeve 505 in the opposite direction and lift the inner tube 503 upwards to compress the compression spring 502, which will easily separate the two first handles 1 and the second handle 2.

[0032] Furthermore, the cable management structure 7 includes multiple cable management racks 701, which are arranged in a ring of three. These cable management racks 701 are arranged laterally on the inner walls of the first handle 1 and the second handle 2. Each set of cable management racks 701 has a rubber elastic block 702 at the center of its front and rear inner walls. Each set of rubber elastic blocks 702 has a force-bearing spring 703 fitted around its outer side. Each set of rubber elastic blocks 702 has a clamping block 704 fixedly connected to one end. The multiple cable management racks 701 are arranged in a ring on the inner walls of the handles. This device is used to organize and secure the hair dryer's power cord, preventing it from swinging or tangling inside the handle. The rubber elastic block 702, the force spring 703, and the clamping block 704 work together. The force spring 703 provides elastic force to the rubber elastic block 702, allowing the clamping block 704 to firmly hold the power cord. Even as the handle swings and rotates during use, the power cord remains securely fixed, preventing any impact on the stability of the internal circuitry due to power cord movement. It also prevents wear on the power cord's outer sheath, avoiding potential short circuits and other safety issues.

[0033] When using the device of this technical solution, the internal air duct structure of the blower is controlled by the reverse button 3 and the blower push block 4 to change the airflow direction, wind speed or other blowing modes. When the reverse button 3 is pressed, the linkage mechanism pushes the blower push block 4 to move, causing the internal air duct structure to change, thereby realizing the reverse blowing of air. The protective structure 6 is composed of a first inner layer 601 and a second inner layer 602. The mounting block 603 on its outer wall is slidably connected to the mounting groove 604 on the inner side wall of the first handle 1 and the second handle 2, and has a convex structure, which ensures that the protective structure 6 is stably installed on the inner side wall of the handle. Moreover, when the handle is subjected to slight impact or vibration, the mounting block 603 can slide in the mounting groove 604 to provide buffer space, absorb impact force, protect the internal structure, and facilitate the disassembly and replacement of the protective structure, making maintenance convenient.

[0034] The positioning block 507 engages with the positioning groove 508 to determine the relative position and orientation of the first handle 1 and the second handle 2 during installation. The compression spring 502 within the upper groove 509 pushes the inner tube 503 into the lower retaining tube 504, achieving axial positioning and elastic connection, thus buffering vibrations experienced by the handles during use. Furthermore, the threaded groove 506 and sleeve 505 on the outer wall, when rotated, tighten the sleeve 505 onto the threaded groove 506, reinforcing the connection between the two handles and ensuring structural stability. This meets the strength requirements of the handles during operation of the hair dryer. When disassembly and maintenance are required, the sleeve 505 is rotated in the opposite direction. By lifting the inner tube 503 and compressing the spring 502, the first handle 1 and the second handle 2 can be separated. The cable management bracket 701 is arranged in a ring on the inner wall of the handle to organize and fix the hair dryer's power cord, preventing the power cord from shaking and getting tangled. The rubber elastic block 702, the force spring 703, and the clamping block 704 work together. The force spring 703 gives the rubber elastic block 702 elastic force, so that the clamping block 704 firmly clamps the power cord. During the use of the hair dryer, even if the handle swings and rotates, the power cord can be fixed, ensuring the stability of the internal circuit connection, while preventing the outer sheath of the power cord from being worn and avoiding safety issues such as short circuits.

[0035] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
