[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] The handheld hair dryer of the preferred embodiment of the utility model is as follows Figure 1-5As shown, the hair dryer includes a housing 10, and the housing 10 includes a wind tube body 101. The two ends of the wind tube body 101 are opened to form an air inlet 1a and an air outlet 1b respectively. The hair dryer also includes a blowing module 20 arranged in the wind tube body 101, and the blowing module 20 includes a fan blade 21, a motor 22 driving the fan blade 21 to rotate, and a positioning member 23 arranged on the outer side wall of the motor 22. A snap-fit ​​position 30 for snap-fitting and fastening is provided on the inner wall of the wind tube body 101 corresponding to the positioning member 23, and the motor 22 can be removably arranged on the snap-fit ​​position 30 along the length direction of the rotating shaft through the positioning member 23. During installation, the motor 22 and the positioning member 23 can be directly installed inside the air outlet 1b of the wind tube body 101, and the motor 22 can be fixed on the inner wall of the wind tube body 101 by the positioning member 23 and the locking position 30. When disassembly is required, the positioning member 23 can be pulled out of the inner cavity of the wind tube body along the air outlet direction to complete the disassembly. There is no need to use tools such as screwdrivers for disassembly. The overall structure is simple, and the disassembly and installation of the motor 22 is convenient and quick. Among them, the matching method of the positioning member 23 and the locking position 30 can be a buckle or a rotating buckle, or an interference fit radially tight, or a magnetic attraction formed by setting a strong magnet. Different matching methods can be selected according to actual needs.

[0028] In this embodiment, the positioning member 23 and the air cylinder body are both cylindrical, the inner diameter of the positioning member 23 is greater than or equal to the diameter of the air inlet 1a, the motor 22 is arranged inside the positioning member 23, and there is a ventilation gap 40 between the motor 22 and the inner wall of the positioning member 23. When the motor 22 is started, the fan blades 21 are driven to rotate to form a high-speed wind beam in the air cylinder body 101 and blow it out through the air outlet 1b, and the airflow passing through the gap 40 can also dissipate heat for the motor 22.

[0029] In this embodiment, a plurality of fixing ribs 50 are provided on the inner wall of the positioning member 23 in the circumferential direction. When assembled in place, the fixing ribs 50 are pressed tightly against the outer wall of the motor 22, so that the motor 22 is fixed and stable.

[0030] In this embodiment, the fixed rib wall 50 is in the shape of a long arc and is arranged along the air outlet direction. A plurality of fixed rib walls 50 are arranged in the same direction so that the airflow in the gap 40 forms a rotating airflow, thereby increasing the uniformity of the blown airflow.

[0031] In the present embodiment, a groove 60 is recessed on the inner wall of the air duct body 101, and the groove 60 forms a snap-fit ​​position 30. The groove 60 passes through the end surface of the air outlet end of the air duct body 101 facing the air outlet. Preferably, the outer wall of the positioning member 23 is interference fit with the inner wall of the groove 60 to facilitate disassembly and assembly. Moreover, during the operation of the motor 22 and the fan blades 21, the reverse thrust generated by the fan blades 21 can also press the fixing member against the side wall of the groove 60 facing the air inlet 1a.

[0032] In this embodiment, a first air guide 70 is provided in the air duct body 101 at the air outlet side of the motor 22. Specifically, the first air guide 70 is conical and its smaller end faces the motor 22 to avoid the formation of turbulence at the tail of the motor 22, thereby affecting the air outlet speed and uniformity. A fixed sleeve 80 is coaxially sleeved on the outer side of the first air guide 70. The inner diameter of the fixed sleeve 80 is greater than or equal to the inner diameter of the fixed member, and the two are preferably the same to ensure that the speed of the airflow will not be reduced. Further, a connecting member 90 connected to the first air guide 70 is provided on the inner wall of the fixed sleeve 80. The connecting member 90 is provided in plurality and evenly distributed along the circumference of the first air guide 70. The connecting member 90 is specifically streamlined to reduce the obstruction to the airflow and at the same time plays a role in fixing the first air guide 70. When assembled in place, the fixing sleeve 80 is pressed against the inner wall of the wind tube body 101, and while acting as the first air guide member 70, it can also press the fixing member against the inner wall of the groove 60 facing the air inlet 1a, further enhancing the stability of the fixing member and the motor 22 after being fixed.

[0033] In this embodiment, the hair dryer also includes an air outlet tube 100 arranged on the air outlet 1b of the air outlet tube body 101. The air outlet tube 100 is provided with a connecting portion 110 adapted to the air outlet 1b. The connecting portion 110 extends into the air outlet 1b and is tightly pressed against the inner wall of the air outlet 1b by interference fit to facilitate disassembly and assembly. Specifically, the inner diameter of the connecting portion 110 is greater than or equal to the inner diameter of the fixed sleeve 80, and preferably the inner diameters of the two are the same.

[0034] In this embodiment, the air outlet port of the air outlet cylinder 100 is in a tapered shape that gradually expands or contracts along the air outlet direction. The expanded tapered structure can be used to disperse the blown airflow, making the airflow soft and comfortable. In order to further disperse the airflow, a second air guide 120 can be arranged inside the air outlet cylinder in the expanded tapered shape. By designing the diameter of the second air guide 120 to be larger than the diameter of the first air guide 70, the blown airflow can be dispersed again. The gradually reduced tapered structure can be used to further gather the blown airflow to form a high-speed airflow, which is applied to occasions requiring high-speed airflow.

[0035] In this embodiment, the shell 10 also includes a handle body 102 vertically arranged on the outer wall of the hair dryer body 101, and an inner cavity 130 is arranged in the handle body 102. The hair dryer also includes a control panel 140 arranged in the inner cavity 130. A heat dissipation air inlet 150 is provided on the handle body 102. The heat dissipation air inlet 150 is located on the end surface of the handle body 102 facing away from the hair dryer body 101, and the control panel 140 is adjacent to the heat dissipation air inlet 150 and the two are directly opposite. A heat dissipation air outlet 160 connected with the inner cavity 130 is provided on the hair dryer body 101. When the fan blades 21 rotate, a low pressure area can be formed at the position of the heat dissipation air outlet 160, and then the external air is sucked into the inner cavity 130 from the heat dissipation air inlet 150 and flows out from the heat dissipation air outlet 160, thereby achieving the purpose of cooling and dissipating the control panel 140. Furthermore, a battery 170 for supplying power to the motor 22 and the control board 140 is disposed in the inner cavity 130 to further increase portability and practicality.

[0036] In addition, in order to avoid blocking the airflow in the inner cavity 130 after installing the fixing member or the fixing sleeve 80 , a connecting hole 180 is provided on the fixing member or the fixing sleeve 80 corresponding to the heat dissipation outlet 160 . Preferably, the connecting hole 180 is provided on the fixing sleeve 80 .

[0037] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
