Fig. 2 is a schematic structural view of the main body of the hand-held hair dryer shown in Fig. 1 .

Detailed ways

The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

Referring to Fig. 1 and Fig. 2, the hand-held hair dryer of the present invention comprises a main body part 1 and a hand-held part 2 which communicate with each other, external air enters the said hand-held part 2 from the bottom end of the said hand-held part 2, and is sent into the said main body Part 1 is finally blown out from the air outlet 3 of the hand-held hair dryer after being heated.

Wherein, the main body 1 is set as a sleeve penetrating front and back, including an air cylinder 4, a central pipe 5, a circuit board assembly 6, a heating assembly 7, a rear end cover 8, an air nozzle assembly 9 and a windshield. The rear end cover 8 and the air nozzle assembly 9 are respectively located at opposite ends of the air cylinder 4, the rear end cover 8 is located at the rear end of the central tube 5, and the air cylinder 4 accommodates the central tube 5 and The heating component 7 and the decorative plate 11 pass through the rear end cover 8 backwards and are exposed to the outside, and the circuit board component 6 , the heating component 7 and the windshield are respectively sleeved on the central tube 5 outside.

Further, the central pipe 5 is a hollow structure penetrating front and back, including a first section and a second section, and the diameter of the second section is larger than that of the first section. In this embodiment, the wall thicknesses of the first section and the second section are the same, of course, according to product requirements, the wall thicknesses of the first section and the second section can also be adjusted adaptively. The material of the central tube 5 is preferably plastic, which can be made by integral injection molding.

The circuit board assembly 6 is located outside the first section of the central tube 5 with a smaller diameter, and partly accommodated in the central tube 5 . The heating component 7 is sleeved on the central tube 5, specifically located outside the second section of the central tube 5 with a larger diameter, and the windshield is located between the circuit board component 6 and the heating component 7, specifically It is located at the junction of the first section and the second section of the central pipe 5 . The main function of the heating element 7 is to heat the passing airflow, turn it into hot air, and blow it toward the direction of the air outlet 3, so as to play a drying role. The heating assembly 7 is electrically connected to the circuit board assembly 6, wherein the circuit board assembly 6 includes a constant temperature automatic electric control element (not marked), and the heating assembly 7 is connected in series with the constant temperature automatic electric control element. When the temperature of the heating component 7 exceeds a predetermined temperature, the constant temperature automatic electric control element cuts off the circuit, thereby playing a protective role and preventing accidents. In this embodiment, the heating element 7 is preferably an electric heating wire, which has a high melting point and can heat up rapidly in a relatively short period of time. Further, the heating element 7 is wound by a multi-turn electric heating wire.

The handle part 2 includes an air outlet end, and the windshield is disposed adjacent to the air outlet end of the main body 1 and partly located inside the air outlet end. The main function of the windshield is to guide the airflow from the handle 2 towards the heating component 7 and prevent the airflow from flowing towards the circuit board assembly 6 . On the one hand, the windshield guides the airflow from the handle 2 toward the air outlet 3 of the hand-held hair dryer, thereby avoiding turbulent flow and making the airflow smoother. On the other hand, the windshield also prevents the airflow heated by the heating component 7 from blowing to the circuit board assembly 6, so as to prevent the stability of the circuit board assembly 6 from being heated by the airflow and increase its temperature, thereby correspondingly improving The stability of the handheld hair dryer.

The front end of the central pipe 5 is also provided with an air nozzle assembly 9, the air nozzle assembly 9 is sleeved on the central pipe 5 and adjacent to the heating assembly 7, and the front end of the main body 1 is provided with an air nozzle assembly 9 Compatible buckle. The air nozzle assembly 9 outputs the hot air heated by the heating assembly 7 from the air outlet 3 , and the air nozzle assembly 9 can also change the shape and speed of the air output from the hand-held hair dryer. In this embodiment, the air nozzle assembly 9 is detachably installed on the central tube 5 through a buckle structure. wind demand.

The central pipe 5 , the heating element 7 and the rear end cover 8 are assembled together along the air outlet direction of the main body 1 , and placed inside the main body 1 from the rear end of the main body 1 forward. After the central tube 5 , the heating component 7 and the rear end cover 8 are placed in the main body 1 , the rear end cover 8 is rotated relative to the main body 1 to form a buckle fixation.

The rear end cover 8 and the central pipe 5 can be integrally formed, or can be separately formed and installed together. When the rear end cover 8 is rotated relative to the main body 1 , it simultaneously drives the air outlet 3 to rotate to form a buckle with the inside of the front end of the main body 1 . The material of the rear end cover 8 is one of metal, alloy, graphene and carbon fiber, which is convenient for heat dissipation. Further, the rear end cover 8 may also include a plurality of operation windows.

Compared with the prior art, the hand-held hair dryer of the present invention is inserted into the sleeve of the main body from the rear to the front after the functional components such as the central cylinder, the heating component and the rear end cover are connected and arranged from the front to the rear, and then rotated to form a buckle Fixed, so that it can be installed in a simple and convenient one-piece, and each of the functional parts is detachable assembly, which is convenient for subsequent maintenance. .

The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, all possible combinations of the technical features in the above-mentioned embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, should be considered as within the scope of this specification.

The above-mentioned embodiments only express several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but should not be construed as limiting the patent scope of the invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention should be based on the appended claims.
