Description

Technical Field

[0001] This utility model relates to the field of hair drying equipment technology, and in particular to a connecting part for the upper and lower shells of a hair dryer with an air inlet filter. Background Technology

[0002] A hair dryer is an electrical device used to quickly dry hair, widely used in homes, hotels, hair salons, and other places. It not only saves time but also protects hair quality to some extent. The main function of a hair dryer is to quickly dry hair using high-speed airflow while avoiding high-temperature damage to the hair and scalp.

[0003] When a hair dryer malfunctions internally, such as a damaged motor or a short circuit, the outer casing needs to be disassembled for repair. If the connectors are difficult to disassemble, repair personnel will need to spend more time and effort, increasing repair costs and difficulty. In severe cases, the inability to disassemble successfully may damage the outer casing, further increasing repair costs. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology by proposing a connecting part for the upper and lower shells of a hair dryer with an air inlet filter. By pulling the pull rod, the connecting column moves the connecting plate, which in turn moves the insertion rod. The insertion rod will disengage from the inside of the fixing hole, and then the mounting bracket can be removed. This saves maintenance time and reduces the risk of shell damage that may be caused by difficult disassembly, thereby reducing maintenance costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A hair dryer with an air inlet filter and an upper and lower outer shell connector includes: an upper shell as the connecting body, a lower shell at the right end of the upper shell, a mounting bracket at the top of the upper and lower shells, fixing rings fixedly connected to both sides of the outer wall of the mounting bracket, connecting posts connected to the inner walls of the fixing rings via sliding components, connecting plates rotatably connected to opposite ends of the connecting posts, insert rods rotatably connected to opposite ends of the connecting plates, pull rods fixedly connected to the top of each connecting post, and springs provided between the fixing rings and the inner walls of the connecting posts.

[0007] Furthermore, the sliding assembly includes sliding grooves located on both sides of the inner wall of the fixed ring, and the inner walls of the sliding grooves are slidably connected to limit plates, with one end of each limit plate fixedly connected to the outer wall of the connecting column.

[0008] Furthermore, each of the upper and lower shells is fixedly connected to a mounting post at one end, and the bottom end of the mounting bracket is fixedly connected to a positioning post, with the inner wall of the positioning post slidably connected to the inner wall of the mounting post.

[0009] Furthermore, the inner walls of the upper and lower shells are provided with fixing holes corresponding to the insertion rods, and the inner walls of the fixing rings are slidably connected to the inner walls of the upper and lower shells.

[0010] Furthermore, one end of each spring is connected to a connecting post, and the other end of each spring is connected to the inner wall of a fixing ring.

[0011] This utility model has the following beneficial effects:

[0012] In this invention, pulling the pull rod drives the connecting column, which in turn drives the connecting plate, which in turn drives the insert rod. The insert rod then disengages from the fixing hole, allowing the mounting bracket to be removed. This saves maintenance time and reduces the risk of damage to the outer casing due to disassembly difficulties, thereby reducing maintenance costs. Attached Figure Description

[0020] 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.

[0021] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a hair dryer with an air inlet filter and an upper and lower shell connecting component, comprising: an upper shell 1 as the connecting body, a lower shell 2 at the right end of the upper shell 1, a mounting bracket 3 at the top of the upper shell 1 and the lower shell 2, a fixing ring 6 fixedly connected to both sides of the outer wall of the mounting bracket 3, a connecting post 9 connected to the inner wall of the fixing ring 6 via a sliding component, a connecting plate 10 rotatably connected to the opposite end of the connecting post 9, a plug rod 11 rotatably connected to the opposite end of the connecting plate 10, a pull rod 12 fixedly connected to the top of the connecting post 9, a spring 13 provided between the fixing ring 6 and the inner wall of the connecting post 9, and the sliding component including a sliding groove 7 located on both sides of the inner wall of the fixing ring 6, a limiting plate 8 slidably connected to the inner wall of the sliding groove 7, and the opposite end of the limiting plate 8 fixedly connected to the outer wall of the connecting post 9.

[0022] Specifically, when disassembling the upper and lower outer shells of the hair dryer, simply pull the lever 12. Under force, the lever 12 will mechanically move the connecting post 9. During this movement, the connecting post 9 will cause the connected plate 10 to rotate. As the connecting plate 10 rotates, the insertion rod 11 also moves. Once the insertion rod 11 has moved to a certain extent, it will disengage from the fixing hole 14. At this point, the mounting bracket 3 can be easily removed. The entire disassembly process is convenient and smooth. This design greatly saves time spent disassembling the outer shell during maintenance, eliminating the need for maintenance personnel to spend considerable effort on disassembly. By removing the difficult parts, the internal components of the hair dryer that need repair can be quickly accessed. Moreover, the risk of damage to the outer casing due to the difficulty of disassembly is greatly reduced. In the past, the outer casing might have been scratched or cracked due to factors such as forced disassembly or improper use of tools. Now these problems can be avoided, thereby reducing maintenance costs. During the movement of the connecting column 9, the limiting plate 8 will slide inside the slide groove 7. The presence of the limiting plate 8 plays a good stabilizing role for the connecting column 9, ensuring that the connecting column 9 remains stable during the movement and will not shake or deviate, thus ensuring the smooth progress of the entire disassembly and subsequent maintenance process.

[0023] Reference Figures 1-3 Mounting posts 5 are fixedly connected to one end of the upper shell 1 and the lower shell 2. A positioning post 4 is fixedly connected to the bottom end of the mounting bracket 3. The inner wall of the positioning post 4 is slidably connected to the inner wall of the mounting post 5. Fixing holes 14 are provided on the inner walls of the upper shell 1 and the lower shell 2 corresponding to the insertion rod 11. The inner walls of the fixing ring 6 are slidably connected to the inner walls of the upper shell 1 and the lower shell 2. One end of the spring 13 is connected to the connecting post 9, and the other end of the spring 13 is connected to the inner wall of the fixing ring 6.

[0024] Specifically, when installing the hair dryer, first align the upper shell 1 and lower shell 2 together. At this time, the positioning post 4 and the mounting post 5 need to be precisely aligned. Then, slowly insert the positioning post 4 into the mounting post 5 to complete the initial positioning. After the positioning post 4 is inserted into place, the fixing ring 6 will be embedded in the outer wall of the upper shell 1 and the lower shell 2, playing a certain auxiliary fixing role. Next, release the pull rod 12. Since the spring 13 was previously in a compressed state, the spring 13 will quickly rebound at the moment the pull rod 12 is released, which will forcefully bounce the connecting post 9. The connecting post 9 will move quickly under the action of the spring 13 and be precisely inserted into the fixing hole 14, thereby achieving a stable fixation of the upper shell 1 and the lower shell 2, and completing the entire installation process.

[0025] Working principle: When the upper and lower shells need to be disassembled, pull rod 12 is pulled to move connecting post 9. When connecting post 9 moves, connecting plate 10 rotates. When connecting plate 10 rotates, insert rod 11 moves. When insert rod 11 moves, it disengages from the inside of fixing hole 14 and then mounting bracket 3 is removed, thus saving maintenance time and reducing the risk of shell damage due to disassembly difficulties, thereby reducing maintenance costs. When connecting post 9 moves, limiting plate 8 slides inside slide groove 7. Limiting plate 8 improves the stability of connecting post 9. During installation, upper shell 1 and lower shell 2 are placed together. Then, positioning post 4 is aligned with mounting post 5 and inserted into mounting post 5 for positioning. When inserted into the correct position, fixing ring 6 is inserted into the outer wall of upper shell 1 and lower shell 2. At this time, pull rod 12 is released. When pull rod 12 is released, spring 13 will spring connecting post 9. When connecting post 9 is springed, it is inserted into fixing hole 14 for fixation.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
