Description

Technical Field

[0001] The invention relates to the field of hair styling appliances, and in particular to a hair styling appliance and an air guide box thereof, and a method for coating graphene in the air guide box. Background Art

[0002] A hair straightener, also known as an electric flat iron, is a type of hair styling tool. Its function, as the name implies, is to straighten the hair. The hair is heated, softened, and then cooled by a heating element to achieve the purpose of straightening the hair. Similarly, by changing the technique, straight hair can be made curly to achieve the purpose of styling. As hair straighteners entered the Chinese household market, they have gradually developed into a must-have product for personal care, as popular as a comb.

[0003] The original hair straighteners rely on ceramic heaters, PTC heaters or MCH heaters to heat the hair when working. However, these methods of heating the hair have an obvious defect: since these heaters need to be heated by direct contact with the hair, they are easy to damage the hair during use. Long-term use will lead to dry hair, split ends and other phenomena.

[0004] With the development of related fields, existing hair straighteners have begun to combine the technology of the original hair dryers. A fan and a heating element are set inside the hair straightener. The airflow generated by the fan blows through the heating element to form hot air, which then heats the user's hair. This heating method is less harmful to the hair than the original direct contact. At the same time, since this type of hair straightener can blow out hot air, it can also be used as a hair dryer, making it more functional.

[0005] In addition to the fan and the heating body for generating hot air, the existing hair straighteners with hot air function on the market also retain the original contact heating method of hair, so that this type of hair straightener has multiple usage methods. For example, the Chinese patent with patent number ZL202411510616.3 discloses: "A hair straightener, comprising a lower handle, an inner cylinder, a heating frame, a motor, a circuit board, a wire protection sleeve, a filter bracket, a tail ring, an upper handle, a lower aluminum plate, a handle cover, a locking twist, an upper cover plate, an upper aluminum plate, a fixing plate, a lower cover plate, an air outlet frame, and a button circuit board. Compared with the prior art, the present invention is based on a hair straightener and has a hair dryer function, and can blow out hot air at high speed, so that the hair straightener and the hair dryer are two-in-one, which is more convenient to use"; However, including the solution in the above patent, this type of hair straightener with hot air blowing function in the prior art has a defect. Since the hair dryer is generally arranged in a cylindrical shape, the blowing port is opened at its end, so the hot air of the hair dryer is uniform when it blows out hot air. However, since the hair straightener is generally in a straight plate shape, the blowing port can only be arranged in a straight strip shape when the blowing port is arranged on the head thereof. Moreover, due to the limited space inside the hair straightener, the air suction port and the air supply motor thereof need to be arranged in the handle, which results in part of the airflow transported from the handle of the hair straightener to the head being blown out from the blowing port before being completely heated by the heating element, and the remaining part of the airflow is blown out from the blowing port after completely passing through the heating element, which results in different temperatures of the hot air blown out from the front and back, and further results in the hot air temperature of the existing hair straightener with hot air blowing function being not uniform enough. Summary of the invention

The hot airflow entering the diffusion air cavity will be diffused on both sides along the longitudinal direction and blown out through the blowing holes on one side of the diffusion air cavity, so that hot air can be formed at the blowing port of the head of the upper component, so as to dry or style the hair located between the heads of the upper component and the lower component; When the hair styling appliance needs to style the hair by direct heating, it is also necessary to first relatively flip the upper component and the lower component to separate the heads, and then flip the upper component and the lower component together after placing the hair between the heads. Then, the second heating device can be controlled to start by pressing the control button, so that the second heating device can heat and style the hair that is in direct contact with it.

[0018] The beneficial effects of the present invention are: 1. A transition air chamber is added to the air supply mechanism of the hair styling appliance, and is divided into a front chamber and a rear chamber by a partition plate, so as to ensure that the airflow flowing through the transition air chamber can be fully heated by the first heating device in the front chamber, thereby ensuring that the hot air blown out from the transition air chamber is fully heated, thereby avoiding the problem of uneven temperature of the blown hot air; 2. A diffusion air cavity is also provided behind the transition air cavity, and the air outlet opening connecting the transition air cavity and the diffusion air cavity is opened in the middle position of the diffusion air cavity in the longitudinal direction, so as to ensure that the hot air entering the transition air wall can be evenly diffused into the entire diffusion air cavity. When the hot air is discharged from the blowing holes on the side of the diffusion air cavity, the air volume at each blowing hole is ensured to be relatively uniform, so that the air volume of the hot air blown out by the hair styling device is also more uniform; 3. An intelligent control button and an intelligent control element are provided. The intelligent control button can be used to start the intelligent control mode of the hair styling appliance with one click. In this mode, the user does not need to perform any further operations. The electronic control panel can automatically adjust the air supply motor and the first heating device according to information such as the use time and the implemented temperature, so as to complete the hair drying or styling, making the hair styling appliance more intelligent and simplifying the operation of the user.

[0019] 4. The inner wall of the air guide box is coated with a graphene coating, so that the first heating device in the air guide box has a higher heating efficiency for the airflow and heats the airflow more evenly, further ensuring the uniformity of the hot air blown out by the hair styling device; 5.
