[0026] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0027] A preferred embodiment of the utility model is a hair dryer with high blowing efficiency and gentle wind force; Figure 1-3 As shown, it includes a housing 3, one end of which is connected to a handle 1, a connecting line 7 is connected to the lower end of the handle, a control board 2 electrically connected to the connecting line is arranged in the handle, and a button 8 is arranged on the handle. A heating component 10 and a motor 11 connected to the control board are arranged in the housing, a first air inlet net 12 is arranged on the side of the housing close to the motor, and a back cover 13 is arranged outside the first air inlet net; an air outlet net 4 is arranged on the side of the housing close to the heating component, a fan 5 is arranged between the air outlet net and the heating component, and the fan is fixed in the housing through a bracket 9. The hair dryer is powered on by connecting the mains through the connecting line, and the working state of the control board 2 is adjusted by the button 8, so that the heating component is heated at different temperatures, and the motor drives the fan to rotate to blow out the hot air, thereby performing the blowing operation.

[0028] Specifically, Figure 2-4 As shown, the housing 3 is set in a three-way form, which includes an air outlet 30, a first air inlet 31 placed at the same horizontal plane as the air outlet, and a second air inlet 32 ​​arranged vertically with the air outlet. A handle connecting column 33 is arranged near the second air inlet of the housing, and the handle is fixed on the outside of the handle connecting column. In order to facilitate the air to enter through the second air inlet, the inside of the handle connecting column is a hollow part 330. An inner ring wall 24 is also arranged at the first air inlet 31, and the radius of the inner ring wall is smaller than the radius of the first air inlet. The rear cover 13 is placed at the first air inlet 31, and in order to facilitate air circulation, a plurality of groups of air inlet holes should be arranged on the rear cover. The first air inlet net 12 is fixed in the housing and placed at the inner ring wall 24, and a plurality of groups of air inlet holes (not shown in the figure) are also arranged on the first air inlet net. The air inlet holes on the first air inlet net should be set as small air inlet holes, and the number can cover the bottom surface of the first air inlet net, so as to prevent large particles of dust from passing through the first air inlet net and entering the housing. A gap 14 may also be left between the outer wall of the first air inlet net and the inner ring wall, and air may circulate through the gap. It should be noted that the radius of the first air inlet net should be larger than the radius of the first air inlet.

[0029] Furthermore, if Figure 1-3 and Figure 7As shown, the second air inlet net 6 is placed at the end of the handle, and a plurality of air inlet holes 60 are arranged on its side, and a conical connecting surface 61 is arranged at the bottom. The connecting line passes through the conical connecting surface and enters the handle to connect with the control panel. The air enters the second air inlet through the air inlet holes on the second air inlet net 6 and then enters the inside of the shell. It should be noted that the first air inlet net can also adopt the same structure as the second air inlet net, except that its air inlet holes are arranged on the conical connecting surface 61, and no air inlet holes are arranged on the side, and its conical connecting surface is arranged corresponding to the inner ring wall. At the same time, the handle is placed outside the end of the handle, and the handle and the handle end can be connected by a conventional detachable connection method, such as locking by screw connection after insertion, or fixing by snap-fit, or connecting by thread, etc., or fixed by injection molding, which will not be described in detail here.

[0030] Furthermore, if Figure 2 and 3 As shown, the heating component 10 is placed between the second air inlet 32 ​​and the air outlet 30, so that the air can be heated by the heating component and then blown out by the fan to form hot air regardless of whether the air enters through the first air inlet or the second air inlet.

[0031] Furthermore, if Figure 2-3 and Figure 5 As shown, a bracket 9 is provided in the shell 3, a fan fixing hole 90 is provided in the middle of the bracket, and a fan connecting column 50 is provided in correspondence with the fan fixing hole of the fan, so as to fix the fan on the bracket. The fan includes multiple sets of blades 51, and the blades are eccentric. The blades of the same shape as the existing fan can be used, and no repetition is made here. The heated air forms hot air under the action of the fan and diffuses to the surroundings. Due to the action of the fan, the diffusion range is wider and the heat dissipation effect is better. Multiple sets of blades cut the hot air into smaller blocks, making the hot air softer and lower in noise. At the same time, the air flow is increased, the blowing efficiency is improved, and the experience of use is better.

[0032] Furthermore, if Figure 6 As shown, multiple groups of anti-breaking parts 70 are provided at the upper end of the connecting line 7, and annular grooves 71 are provided between the anti-breaking parts. The radius of the anti-breaking part increases as it is closer to the handle end, so that the anti-breaking part is in an inverted cone shape, which is convenient for protecting the connecting line during the pulling process of the hair dryer and avoids the breakage of the connecting line.

[0033] When in use, plug the connecting wire 7 into the socket and connect it to the AC power to power the hair dryer. Press the button 8 to start the hair dryer. The control panel 2 drives the motor 11 to rotate so that air enters the shell through the first air inlet net 12 and / or the second air inlet net 6, and then passes through the heating component to heat the air to form hot air. The hot air is then blown out by the fan to act on the working position of the hair dryer. Since the fan cuts the hot air into blocks, the utilization rate of the hot air is higher, the noise is smaller, and the blowing work is completed faster.

[0034] It should be understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present invention.
