[0023] As attached Figure 1 The image shows the nozzle assembly of the hair dryer of this utility model, including an air guide tube 1. The air guide tube 1 includes an air inlet end 11 for connection with the hair dryer and an air outlet end 12 away from the air inlet end 11. An air duct is formed between the air inlet end 11 and the air outlet end 12, and the air duct gradually widens from the air inlet end 11 to the air outlet end 12. A detachable comb plate 2 is installed inside the air duct near the air outlet end 12. Several comb teeth 3 are installed on the comb plate 2, and the comb teeth 3 extend outside the air guide tube 1, as shown in the attached figure. Figure 5 As shown, the comb plate 2 has several holes 21, and a grid 22 is formed between adjacent holes 21. The holes 21 are distributed around the comb teeth 3, and the comb teeth 3 are located at the junction of the grid 22, so that the connection of the comb teeth 3 has sufficient strength. When in use, the comb teeth 3 can be inserted into the hair to loosen the wet hair that is stuck together, making it easier to blow dry. You can comb your hair while blow-drying, which improves the efficiency of blow-drying.

[0024] A removable cover plate 4 is installed inside the air duct, located on the outside of the comb plate 2. The cover plate 4 has several air vents 41 corresponding to the comb teeth 3, as shown in the attached figure. Figure 2 As shown, the comb teeth 3 pass through the center of the vent 41. The vent 41 and the hole 21 are intersected. The projection of the grid 22 on the cover plate 4 divides the vent 41 into small holes surrounding the comb teeth 3, so that the air blows out from around the comb teeth 3. The combed hair is exposed to the dispersed airflow, and the hair dries faster and more evenly.

[0025] In this embodiment, the comb teeth 3 are arranged in a square array, the holes 21 are square, and the comb teeth 3 are located at the four corners of the holes 21. While ensuring sufficient strength, the ventilation area of ​​the comb plate 3 is increased. The ventilation opening 41 is also square. The projection of the grid 22 on the cover plate 4 divides the ventilation opening 41 into four square holes surrounding the comb teeth 3, so that the air is evenly discharged and the ventilation area is increased.

[0026] When hair gets tangled on the comb teeth 3 after use, simply remove the cover plate 4 to remove the hair from the comb teeth 3. There is no need to pick and pull the hair, making cleaning easy.

[0027] As attached Figure 5 As shown, several axially extending columns 23 are formed around the edge of the comb plate 2. A slot 231 is formed on the side of the column 23 near the inner wall of the air guide duct 1. The end of the slot 231 near the air inlet 11 is open, and the end of the slot 231 near the air outlet 12 is sealed, as shown in the attached diagram. Figure 4 As shown, the inner wall of the air duct 1 has a protruding rib 13 corresponding to the slot 231. The slot 231 and the protruding rib 13 are axially connected. During installation, the comb plate 2 is pushed inward from the air inlet end 11, so that the protruding rib 13 is embedded in the slot 231 and securely connected. This installation structure allows the end of the protruding rib 13 to abut against the comb plate 2, keeping the comb plate 2 stable when the comb teeth 3 come into contact with the scalp or encounter other resistance. In this embodiment, the column 23 is elastic, and the size of the protruding rib 13 gradually decreases from the outside to the inside along the axial direction. After the protruding rib 13 enters the slot 231, the end of the column 23 will contract inward to provide a certain wrapping effect on the protruding rib 13, preventing the protruding rib 13 from easily coming out of the slot 231, making the connection more reliable. When it is necessary to remove the comb plate 2, it can be pushed out from the air inlet end 11 by using a tool to hold the comb plate 2.

[0028] As attached Figure 4 As shown, the inner wall of the air duct 1 has an annular limiting strip 14 located on the outer side of the comb plate 2. The inner diameter of the limiting strip 14 is larger than the outer diameter of the comb plate 2. Parallel and spaced baffles 15 are formed on the outer side of the limiting strip 14. The cover plate 4 can be pressed and inserted between the limiting strip 14 and the baffles 15. The air outlet 12 of the air duct 1 is elliptical, and the shape of the cover plate 4 corresponds to the air outlet 12. A long strip-shaped leverage groove 42 is formed on the edge of the cover plate 4 near the major axis of the ellipse. When disassembling the cover plate 4, it can be easily pried open from the leverage groove 42 with a tool. Installation and disassembly are convenient.

[0029] The air duct 1 is equipped with an air guide 5 to ensure even airflow distribution, prevent airflow from concentrating in certain areas and generating excessively high temperatures, protect fragile and easily damaged hair, make blow-drying gentler, and prevent local hair from becoming dry, split, or damaged due to excessive heat.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
