[0036] The following will be combined with the attached Figure 1-6 A detailed introduction to this application is given.

[0037] The present application provides a hair dryer, including a handle 2 and a main body 1, wherein the main body 1 is connected to the upper end of the handle 2, and the lower end of the handle 2 is connected to a power cord 3, and the handle 2 is provided with a switch and a gear adjustment mechanism of the hair dryer, and the handle 2 is provided with electronic components such as a circuit board, and the main body 1 includes a shell 11 and a hot air component provided inside the shell 11, and the hot air component generates hot air when working, and the user holds the handle 2 and aligns the air outlet on the main body 1 with the hair to dry the hair and style the hair. Specifically, the shell 11 of the main body 1 is cylindrical, and the hot air component is provided inside the shell 11, and the hot air component includes a driving motor 13, a fan blade 12, and a heating component 15. When the hair dryer is working, the driving motor 13 drives the fan blade 12 to rotate to generate airflow, and the airflow is heated by the heating component 15 and then discharged through the air outlet, and the hot air can quickly dry and style the hair.

[0038] The hair dryer of the present application also has a negative ion function. Specifically, the heating assembly 15 of the present application includes a heating bracket and a heating wire 153, the heating bracket includes an inner bracket 152 and an outer bracket 151, the inner bracket 152 is arranged inside the outer bracket 151, and an air duct 100 is formed between the inner bracket 152 and the outer bracket 151, and the heating wire 153 is installed inside the air duct 100. At the same time, the inner bracket 152 is a hollow cylindrical structure, and the inner bracket 152 forms an installation cavity 200 inside. The drive motor 13 partially extends into the installation cavity 200, and the drive motor 13 drives the fan blade 12 to rotate to generate airflow into the air duct 100, which is heated by the heating wire in the air duct 100 and discharged through the air outlet. In order to realize the negative ion function, a negative ion generator 14 is provided in the installation cavity 200, and the negative ion generator 14 is installed at one end of the installation cavity 200 close to the air outlet, and the emission needle 142 of the negative ion generator 14 extends into the air duct 100.

[0039] Since the negative ion generator 14 of the hair dryer of the present application is arranged in the installation cavity 200 inside the inner bracket 152, the negative ion generator 14 is not arranged in the air duct 100, and will not hinder the airflow, and will not affect the air volume and wind speed; the emission needle 142 of the negative ion generator 14 is arranged near the air outlet of the air duct 100, and the airflow is concentrated to the emission needle 142, which increases the release of negative ions and improves the release concentration of negative ions. At the same time, since the negative ion generator 14 is arranged inside the inner bracket 152, the space utilization is more efficient, and the entire hair dryer can be made smaller, which reduces the cost and is more beautiful.

[0040] The negative ion generator 14 includes a negative ion high-voltage package 141 and an emission needle 142 electrically connected to the negative ion high-voltage package 141, and the emission needle 142 extends outward from the inner bracket 152 to the air duct 100. The air duct 100 extends along the axial direction of the heating component 15, and the emission needle 142 has a first part perpendicular to the extension direction of the air duct 100, and a second part parallel to the extension direction of the air duct 100, and the first part is connected to the second part. In this way, the negative ion generator 14 is exposed to more airflow, which can increase the concentration of negative ions and improve the hair drying effect of the hair dryer.

[0041] In a preferred embodiment, a through hole 1523 is provided on the inner bracket 152 to allow the emission needle 142 to pass through. The emission needle 142 passes through the through hole 1523 and extends into the air duct 100. In this way, the through hole 1523 can allow the emission needle 142 of the negative ion generator 14 to pass through on the one hand, and can also fix the negative ion generator 14 on the other hand, thereby ensuring that the negative ion generator 14 is reliably fixed.

[0042] In another preferred embodiment, a through groove is provided at the end of the inner bracket 152 near the air outlet, and the slot of the through groove passes through the end of the inner bracket 152 near the air outlet. The emission needle 142 can extend into the air duct 100 from the through groove. When the emission needle 142 is aligned with the slot of the through groove, the emission needle 142 naturally extends into the air duct 100 when the negative ion generator 14 is installed.

[0043] In one example, the inner bracket 152 is composed of a hollow fixing frame 1522 and an inner shell 1521 arranged outside the fixing frame 1522, an air duct 100 is formed between the inner shell 1521 and the outer bracket 151, and the installation cavity 200 is formed inside the fixing frame 1522. The fixing frame 1522 can support the inner shell 1521, thereby improving the strength of the inner bracket 152. In addition, the inner shell 1521 can prevent hot air from entering the installation cavity 200, thereby preventing the drive motor 13 from being overheated and damaged, and improving the service life of the drive motor 13.

[0044] In order to improve the safety of electricity use, in the present application, the outer bracket 151 and the inner shell 1521 are preferably supported by mica boards. The mica boards can reduce heat loss and increase the air outlet temperature of the hair dryer. At the same time, the mica boards can separate the heating wire 153 and the driving motor 13, reduce the heat transmission into the installation cavity 200, and can isolate the heating wire 153 and the driving motor 13 to achieve strong and weak electricity separation. In addition, in order to improve the air outlet effect, a plurality of partitions 1524 are arranged between the inner shell 1521 and the outer bracket 151. The plurality of partitions 1524 are arranged at intervals along the circumference of the air duct 100 to divide the air duct 100 into a plurality of sub-air ducts 100. The plurality of sub-air ducts 100 can guide the airflow and improve the blowing effect. The negative ion generator 14 is preferably provided with a plurality of emission needles 142, each emission needle 142 extends into a different sub-air duct 100, which can increase the concentration of negative ions and improve the hair drying effect.

[0045] The negative ion generator 14 of the present application includes a negative ion high-voltage package 141, a copper belt 143, and an emission needle 142, and the emission needle 142 is connected to the negative ion high-voltage package 141 through the copper belt 143. The negative ion high-voltage package 141 is well connected and fastened to the emission needle 142 by the connection method of the copper belt 143. Specifically, the emission needle 142 is stamped from a stainless steel sheet, with a sharp needle tip and a small size; the needle tip extends into the air duct 100 without any obstruction, and the needle tip can feel the wind blown out of the entire air duct 100, thereby increasing the release of negative ion concentration.

[0046] In order to achieve reliable fixation of the negative ion generator 14, a slot 1525 and a buckle 1526 for limiting the negative ion generator 14 are provided on the fixing frame 1522 of the inner bracket 152. The negative ion high-voltage package 141 is first installed in the slot 1525. The slot 1525 can limit the negative ion high-voltage package 141 so that the emission needle 142 of the negative ion generator 14 can be aligned with the through hole 1523 on the inner bracket 152 to ensure smooth installation. The buckle 1526 on the fixing frame 1522 can finally limit the negative ion high-voltage package 141 to ensure reliable installation of the negative ion generator 14 on the inner bracket 152 and avoid shaking during use.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the present invention are covered by the scope of the claims of the present invention and will not be listed one by one here.
