[0034] Specifically, the filtering component 2 is located at the air inlet end of the blower component 4, filtering the airflow entering the blower component 4. Before the airflow enters the blower component 4, other impurities such as hair and dust are blocked by the filtering component 2, preventing them from entering the interior of the blower component 4, reducing the accumulation of pollutants inside the blower component 4, and prolonging the service life of the hair dryer. Moreover, when the airflow passes through the filtering component 2, the turbulent airflow will be dispersed and redirected to form a smooth airflow, avoiding the formation of turbulence and vortices, and preventing the occurrence of airflow disturbance inside the blower component 4, thereby reducing the noise generated when the hair dryer is in use.

[0035] It should be specifically noted that in this embodiment, the drive motor in the blower component 4 is a high-speed brushless motor with a speed of 100,000 revolutions per minute, making the hair dryer lighter and significantly superior to similar products in terms of performance such as wind speed, air volume, and air pressure.

[0036] For the hair dryer proposed in this embodiment, the filtering component 2 is arranged at the air inlet end of the blower component 4, preventing impurities such as hair and dust from entering the interior of the blower component 4 and prolonging the service life of the hair dryer. Moreover, the filtering component 2 can disperse and redirect the turbulent airflow to form a smooth airflow, reducing the noise generated when the hair dryer is in use.

[0037] Please refer to Figures 2 to 3 , the filtering component 2 is detachably connected to the housing component 1.

[0038] Specifically, the filtering component 2 is detachably connected to the air duct 11 in the housing component 1, facilitating the user to clean or replace the filtering component 2 and reducing the maintenance cost of the hair dryer. In this embodiment, the filtering component 2 is magnetically connected to the housing component 1.

[0039] In one embodiment, the filtering component 2 is installed on the air duct 11 in the housing component 1 by screws.

[0040] Please refer to Figures 2 to 4 , the filtering component 2 includes: a cover plate 21, a bracket 22 installed on the cover plate 21, and a filter net 23 installed on the bracket 22. The bracket 22 is connected to the cover plate 21, and the filter net 23 radially covers the air inlet end of the blower component 4. The cover plate 21 is used to install the bracket 22 on the housing component 1.

[0041] Specifically, the filter net 23 is installed on the bracket 22, and then magnetically connected to the air duct 11 of the housing component 1 through the cover plate 21, making the filtering component 2 an integral whole, facilitating the user to disassemble the filtering component 2 from the air duct 11 of the housing component 1 for cleaning.

[0042] In one embodiment, the filter screen 23 is detachably connected to the bracket 22. When the filtering performance of the filtering component 2 deteriorates, the user only needs to replace the filter screen 23, which reduces the maintenance cost compared to replacing the entire filtering component 2.

[0043] Please refer to Figure 3 , in this embodiment, a protruding portion 211 is provided on the outer side of the cover plate 21. Since the filtering component 2 is magnetically connected to the housing component 1, the user only needs to push the protruding portion 211 to remove the filtering component 2 from the air duct 11 of the housing component 1 without the need for additional tools.

[0044] Please refer to Figures 3 to 4 , the hair dryer further includes: a magnetic attraction component 3, and the magnetic attraction component 3 includes: a first magnetic attraction member 31 provided on the housing component 1 and a second magnetic attraction member 32 provided on the cover plate 21.

[0045] Specifically, the first magnetic attraction member 31 is installed on the air duct 11 of the housing component 1, and the second magnetic attraction component 3 is installed on the cover plate 21. The magnetic connection between the first magnetic attraction member 31 and the second magnetic attraction member 32 provides a stable attraction force to ensure that the filtering component 2 will not easily move or fall off the air duct 11 during use. The magnetic connection between the filtering component 2 and the air duct 11 facilitates the user to disassemble the filtering component 2 for cleaning or replacement.

[0046] In one embodiment, the first magnetic attraction member 31 and the second magnetic attraction member 32 are respectively two magnets that attract each other. The use of a magnet structure for the first magnetic attraction member 31 and the second magnetic attraction member 32 can ensure the magnetic attraction force when the filtering component 2 is connected to the housing component 1.

[0047] In one implementation, the first magnetic attraction member 31 is a magnet, and the second magnetic attraction member 32 is a metal block, and the metal block can be an alloy commonly used in industry, etc.

[0048] Please refer to Figure 3 , the housing component 1 is provided with a mounting position 14, and the first magnetic attraction members 31 are provided at both ends of the mounting position 14.

[0049] Specifically, the mounting position 14 is provided on the air duct 11 of the housing component 1, and the mounting position 14 is in an open shape. The open-shaped mounting position 14 and the first magnetic attraction members 31 located at both ends of the mounting position 14 can guide the installation of the filtering component 2 and improve the installation efficiency of the filtering component 2.

[0050] Please refer to Figure 2 , the housing component 1 includes: an air duct 11 and a handle 12 connected to the side of the air duct 11. The air duct 11 and the handle 12 are connected in an L shape or a T shape. It can be understood that the longitudinal central axis of the handle 12 is perpendicular to the transverse central axis of the air duct 11, which is convenient for the user to operate the hair dryer proposed in this embodiment.

[0051] In one embodiment, the handle 12 is columnar, and the air duct 11 is columnar. The columnar handle 12 allows the user's fingers to be evenly distributed during use, reducing local pressure and improving the holding comfort. The columnar air duct 11 can reduce the turning or blocking of the air flow inside the air duct 11, reduce the resistance of air flow, and reduce the noise during the operation of the hair dryer.

[0052] In this embodiment, a receiving cavity 15 and a display board 16 are further provided on the air duct 11. The display board 16 is clamped in the receiving cavity 15 to prevent the display board 16 from being impacted by external forces.

[0053] Please refer to Figure 6 , the ventilation cavity 13 includes: a first air duct 131 and a second air duct 132 that are in communication with each other. Both the first air duct 131 and the second air duct 132 are provided in the air duct 11. The first air inlet 111 and the air outlet 112 are both provided in the air duct 11. The air outlet 112 is in communication with the first air duct 131, and the first air inlet 111 is in communication with the second air duct 132.

[0054] Specifically, the fan assembly 4 is provided in the first air duct 131. During use, the fan assembly 4 drives the air flow to enter the second air duct 132 from the first air inlet 111, then flows from the second air duct 132 to the first air duct 131 and is blown out from the air outlet 112, avoiding the disturbance of the air flow inside the air duct 11 and reducing the noise during the use of the hair dryer.

[0055] Please refer to again Figure 6 , the ventilation cavity 13 further includes: a third air duct 133. The third air duct 133 is provided in the handle 12. The third air duct 133 is in communication with the first air duct 131. The handle 12 is provided with a second air inlet 121, and the second air inlet 121 is in communication with the third air duct 133.

[0056] Specifically, the second air inlet 121 and the third air duct 133 are provided in the handle 12. The air flow can enter the fan assembly 4 from both the first air inlet 111 and the second air inlet 121 at the same time, increasing the air intake volume. When the driving motor of the fan assembly 4 has the same power, more air volume is output, making the hair dryer proposed in this embodiment more energy-efficient.

[0057] When the hair dryer proposed in this embodiment is in use, the fan assembly 4 drives the air flow to enter the ventilation cavity 13 from both the first air inlet 111 and the second air inlet 121 at the same time. The air flow entering the housing assembly 1 from the first air inlet 111 enters the first air duct 131 through the second air duct 132. The air flow entering the housing assembly 1 from the second air inlet 121 enters the first air duct 131 through the third air duct 133. The air flow passes through the first air duct 131 and is blown out from the air outlet 112. Adopting the air flow design of multiple air ducts can reduce the noise generated by the high-speed air flow and its own operation during the operation of the fan assembly 4.

[0058] Please refer to Figure 5 and Figure 6 The hair dryer further includes a heating element 6, the heating element 6 is installed on the air duct 11, and the fan assembly 4, the heating element 6 and the air outlet 112 are arranged in sequence.

[0059] Specifically, the heating element 6 is adjacent to the air outlet 112, so that the heated air flow can be quickly transferred to the user, reducing the loss of hot air during transmission.

[0060] Please refer to again Figure 5 and Figure 6 The hair dryer further includes an electronic control board 5, the electronic control board 5 is installed on the handle 12, and both the heating element 6 and the fan assembly 4 are controlled by the electronic control board 5.

[0061] Specifically, the electronic control board 5 can adjust the power of the heating element 6 and the fan assembly 4 and monitor the working state, avoiding safety hazards such as overheating and overload, and improving the use safety.

[0062] In this embodiment, a plurality of buttons 7 are provided on the handle 12, and the plurality of buttons 7 are all electrically connected to the electronic control board 5. The plurality of buttons 7 include: a power on / off button, a wind speed adjustment button, a temperature adjustment button, a cold and hot air switching button, and a mode switching button.

[0063] Compared with the prior art, in the hair dryer proposed by the present utility model, the filtering assembly 2 is arranged at the air inlet end of the fan assembly 4, preventing impurities such as hair and dust from entering the interior of the fan assembly 4, and improving the service life of the hair dryer. Moreover, the filtering assembly 2 can disperse and redirect the disordered air flow to form a stable air flow, reducing the noise generated when the hair dryer is in use.

[0064] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto.
