DETAILED DESCRIPTION
[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0026] Please refer to Figures 1-6 The present application provides a technical solution: a folding hair dryer, which comprises an air duct assembly 1 and a handle 2 rotatably connected with the air duct assembly 1. A heating assembly 10 is installed in the air duct assembly 1, so that the air blown out of the air duct assembly 1 becomes hot air. A noise reduction dust screen 11 is arranged at the air inlet end of the air duct assembly 1 and in the handle 2. The noise reduction dust screen 11 is a layered structure with holes. When the hair dryer is used, the air flow is introduced into the handle 2 from the tail end of the handle 2, and then is guided to flow into the air duct assembly 1. The holes of the noise reduction dust screen 11 disperse the air flow gathered together when the air flow flows in the handle 2 and flows into the air duct assembly 1, so that the air flow is regularly guided to flow by being separated and dispersed through the holes. Thus, the air flow is prevented from colliding and generating noise. An air gathering cover 12 is arranged at the air outlet end of the air duct assembly 1. The air outlet end of the air gathering cover 12 is folded, so that it can gather the air to be blown out of the air duct assembly 1 at the air outlet end of the air duct assembly 1, thereby increasing the pressure and improving the air speed.
[0027] The air duct assembly 1 comprises an air duct shell 13, an inner duct 14 arranged in the air duct shell 13, and a heating assembly 10 arranged in the inner duct 14. The inner duct 14 is provided with an annular groove 140 at an air inlet end. The handle 2 is provided with an annular convex ring 20 corresponding to the annular groove 140 at the end close to the air duct assembly 1. The air duct assembly 1 is rotatable around the handle 2 by the limiting rotation cooperation between the annular groove 140 and the annular convex ring 20. The air duct shell 13 is provided with a slope at the end close to the handle 2, and the handle 2 is also provided with a slope at the end close to the air duct assembly 1. Therefore, when the air duct assembly 1 is not rotated, the slopes on the air duct shell 13 and the handle 2 correspond to each other. By rotating the air duct assembly 1, the limiting rotation between the annular groove 140 and the annular convex ring 20 is achieved, so that the relative position between the two slopes on the air duct shell 13 and the handle 2 can be adjusted, and the air duct assembly 1 and the handle 2 are arranged in a 7-shaped manner, thereby achieving the folding of the hair dryer.
[0028] The heating assembly 10 comprises a plurality of mica sheets 100 for heating air to blow hot air. The mica sheets 100 are arranged in intersecting manner to increase the heating area. The heating assembly 10 further comprises a heat insulation mica paper cylinder 101 sleeved on the periphery of the mica sheets 100. The heat insulation mica paper cylinder 101 is used for heat insulation of the mica sheets 100 to avoid overheating of the air duct shell 13. A noise reduction and dust prevention net 11 arranged on the air duct assembly 1 is arranged at the end of the heat insulation mica paper cylinder 101 close to the handle 2.
[0029] The air collecting cover 12 is arranged in the air duct shell 13 and at the end of the heat insulation mica paper cylinder 101 away from the handle 2. The air outlet safety net 120 is arranged at the air outlet end of the air collecting cover 12, which is mainly used to avoid scalding caused by accidental finger touch into the air duct assembly 1.
[0030] The inner duct 14 comprises a duct body 141 and a connecting elbow 142 connected to the duct body 141. The annular groove 140 is arranged on the connecting elbow 142. The connecting elbow 142 is further provided with a positioning ball 143 in rotation cooperation therewith. The handle 2 is provided with an annular table 21 corresponding to the positioning ball 143. The annular table 21 is provided with two mutually corresponding positioning grooves 22. The relative rotation angle between the annular convex ring 20 and the annular groove 140 is 180°. Therefore, by providing the two mutually corresponding positioning grooves 22, when the air duct assembly 1 is rotated to the position, the positioning ball 143 can be limitedly matched with the positioning grooves 22, and a "ding" sound will occur when the positioning ball 143 is embedded in the positioning groove 22, thereby prompting the rotation to the position.
[0031] The circuit board 23 is electrically connected with the mica sheet 100 in the heating assembly 10, and an air inlet cylinder 24 is further arranged at the tail end of the handle 2, the side of the air inlet cylinder 24 is also a mesh structure, so that dust and impurities are avoided to be inhaled, and a switch knob 25 in sliding connection with the handle 2 is further arranged on the handle 2, and the start and stop of the hair dryer can be controlled by pushing the switch knob 25.
[0032] The hair dryer has the advantages that: when the hair dryer is used, the mesh holes on the noise reduction and dust prevention net 11 can disperse the airflow, so that the airflow is avoided to gather together to cause mixed flow and collision to generate wind noise, and the air outlet cover 12 is arranged at the air outlet end of the air cylinder assembly 1, when the hair dryer is used, the air outlet cover 12 can collect the air to improve the air pressure in the air cylinder assembly 1, and the air speed is faster when the air in the air cylinder assembly 1 is blown out.
[0033] Finally, it should be noted that the above only for the preferred examples of the utility model, and not for limiting the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can modify the technical scheme recorded in the foregoing embodiments, or equivalent replacement for part of the technical features. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
