Description

Technical Field

[0001] This utility model belongs to the technical field of hair dryer cover plates, specifically relating to a hair dryer cover plate that is easy to fix. Background Technology

[0002] Hair dryer covers are usually located at the rear or side of the device to prevent foreign objects from entering the dryer, thus avoiding damage to critical components such as the fan, motor, and heating element, and extending the dryer's lifespan. For example, a cover at the air inlet can prevent dust, hair, and other debris from entering.

[0003] In traditional technology, the cover plate is snapped onto the hair dryer using clips. To ensure a tight seal and a close fit between the cover plate and the hair dryer, when the cover plate needs to be removed, a blade or thin metal object is inserted into the gap between the cover plate and the hair dryer and pried outwards to separate the clips. The clips are usually made of plastic and are small in size, so there is a chance that the clips will break when pried, making it impossible for the cover plate to continue to fit with the hair dryer.

[0017] This specific embodiment is a hair dryer cover plate that is easy to fix, and its structural diagram is shown below. Figure 1-6 As shown, the hair dryer includes a hair dryer body 1. A through groove 2 is provided at one end of the hair dryer body 1. A cover plate 3 is slidably connected inside the through groove 2. A grid mesh 4 is fixedly connected to the middle of the inside of the cover plate 3. A locking post 5 is fixedly connected to the outside of the cover plate 3. A connecting groove 6 is provided on the inner side wall of the through groove 2 at a position corresponding to the locking post 5. An arc-shaped groove 7 is provided at one end of the connecting groove 6. A U-shaped frame 8 is fixedly connected to the inner side wall of the through groove 2 and outside the arc-shaped groove 7. A pressing block 9 is symmetrically slidably connected inside the U-shaped frame 8. Through the design of the grid mesh 4 in the middle of the cover plate 3, and since the cover plate 3 is located at the air inlet of the hair dryer body 1, the grid mesh 4 will block external debris and prevent it from entering the interior of the hair dryer body 1. By inserting the cover plate 3 into the interior of the through groove 2, the locking post 5 will then enter the interior of the connecting groove 6. The cover plate 3 will then be pushed until the locking post 5 is in contact with the other end of the connecting groove 6. The cover plate 3 will then be rotated to allow the locking post 5 to slide inside the arc-shaped groove 7 and then into the interior of the U-shaped frame 8, completing the installation. In this embodiment, the interiors of the connecting groove 6 and the arc-shaped groove 7 are interconnected. The two sets of extrusion blocks 9 are fixedly connected to the opposite sides with a first spring, and the adjacent sides of the extrusion blocks 9 are coated with rubber particles. After the locking post 5 enters the interior of the U-shaped frame 8, it will squeeze the extrusion block 9. Then the extrusion block 9 will contact the locking post 5 and slide in opposite directions under the energy storage of the extension and retraction of the first spring until the locking post 5 is completely inside the interior of the U-shaped frame 8. Then the extrusion block 9 will reset and block and limit the locking post 5, thus completing the fixation after installation. Secondly, in this embodiment, a fixed sleeve 10 is symmetrically fixedly connected to one end of the hair dryer body 1. A compression sleeve 11 is slidably connected inside the fixed sleeve 10. A second spring 12 is fixedly connected to the top of the inner side of the compression sleeve 11. A plug 13 is fixedly connected to the bottom of the second spring 12. A limit frame 14 is fixedly connected to the top of the inner side of the fixed sleeve 10. The plug 13 is slidably connected inside the limit frame 14. By pressing the compression sleeve 11 with a finger, the fixed sleeve 10 limits the compression sleeve 11, causing it to move along a predetermined path. Then, the second spring 12 is compressed. At this time, the plug 13 will slide inside the limit frame 14. Furthermore, in this embodiment, the insertion post 13 extends into the interior of the through groove 2 and is slidably connected to the through groove 2. An insertion hole 15 is provided on the surface of the cover plate 3 at a position corresponding to the insertion post 13. Guide blocks 16 are symmetrically fixedly connected to the inner sidewall of the fixing sleeve 10. One side of the guide block 16 is designed with an inclined structure. An inclined groove is provided inside the insertion post 13. A driven rod 17 is slidably connected inside the inclined groove. The driven rod 17 is designed with an inclined structure. Connecting blocks 18 are fixedly connected at both ends of the driven rod 17 at positions corresponding to the guide block 16. When the compression sleeve 11 is lowered, the guide block 16 will follow it and lower synchronously. Then the guide block 16 will compress the connecting block 18. The surfaces in contact with each other are both designed with an inclined surface, so that the guide block 16 will generate a pushing force on the connecting block 18. Subsequently, the driven rod 17 will slide inside the inclined groove and generate a lifting force on the inclined groove. At the same time, it will drive the insertion post 13 to rise and apply a reaction force to the second spring 12.

[0018] Furthermore, in this embodiment, a slot is provided on the inner sidewall of the limiting frame 14, and the driven rod 17 passes through the outside of the slot. Multiple sets of guide vanes 19 are fixedly connected to the left end of the cover plate 3. The guide vanes 19 have sound-absorbing holes 20 inside. Through the design of the guide vanes 19, a uniform and robust airflow is formed, which enhances the wind-gathering effect and maintains the wind-gathering state to propagate a long distance. When the sound wave propagates into the interior of the sound-absorbing hole 20, through the reflection and diffraction of the inner wall, some of the sound energy will be converted into heat energy and dissipated, thereby reducing noise.

[0019] When using the device of this technical solution, pressing the squeezing sleeve 11 with a finger, and the fixing sleeve 10 limiting the squeezing sleeve 11, causes it to move along a predetermined path. The guide block 16 descends synchronously, and then the guide block 16 squeezes the connecting block 18. The contact surfaces of the two are both designed with slopes, so that the guide block 16 generates a pushing force on the connecting block 18. Subsequently, the driven rod 17 slides inside the inclined groove and generates a lifting force on the inclined groove. At the same time, it drives the insert post 13 to rise and applies a reaction force to the second spring 12. By inserting the cover plate 3 into the through groove 2, the locking post 5 will then enter the connecting groove 6. The cover plate 3 is then pushed further until the locking post 5 engages with the connecting groove. The other end of 6 is attached, and then the cover plate 3 is rotated to allow the locking post 5 to slide inside the arc groove 7 and then enter the U-shaped frame 8. After the locking post 5 enters the U-shaped frame 8, it will squeeze the pressing block 9. Then the pressing block 9 contacts the locking post 5 and slides in the opposite direction under the extension and retraction of the first spring until the locking post 5 is completely inside the U-shaped frame 8. Then the pressing block 9 resets and blocks and limits the locking post 5, completing the fixation after installation. Then the pressing sleeve 11 is released. Under the action of the second spring 12, the insertion post 13 resets and is inserted into the insertion hole 15. Compared with the existing hair dryer cover plate, this utility model can improve the overall practicality of the hair dryer cover plate through design.

[0020] 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.
