[0027] Please refer to Figures 1-5 The utility model provides technical schemes:

[0028] A adjustable air volume's electric hair drier, including handheld shell 1, the rear side fixed connection of handheld shell 1 has shell 2, the bottom side of shell 2 inside is provided with inner shell 3, and the top of inner shell 3 is clamped with casing 4, and casing 4 is located at the top side in the inside of shell 2, and the inside of casing 4 is provided with blowing structure 5, and the outside of casing 4 is provided with adjusting mechanism 6, and adjusting mechanism 6 is electrically connected with blowing structure 5.

[0029] Adjusting mechanism 6 includes the control circuit board 61 of setting in the inside of handheld shell 1, and control circuit board 61 is electrically connected with blowing structure 5, and the top of control circuit board 61 is electrically connected with start button 62, and the rear side of the top of control circuit board 61 is provided with air volume adjusting gear 63, and the top of the outside of casing 4 is provided with gear cover 64, and gear cover 64 is engaged with air volume adjusting gear 63, and the outside of gear cover 64 is clamped with rotating movable ring 65.

[0030] In the embodiment, when the start button 62 is pressed, the control circuit board 61 receives a signal, and the blowing structure 5 starts to work. For the adjustment of the air volume, the gear sleeve 64 is driven to rotate by rotating the movable ring 65, and the rotation of the gear sleeve 64 drives the air volume adjusting gear 63 to rotate because the gear sleeve 64 is engaged with the air volume adjusting gear 63. The air volume adjusting gear 63 transmits the rotation information to the control circuit board 61, and the control circuit board 61 adjusts the power or rotating speed of the blowing structure 5 according to the information, so as to flexibly and accurately adjust the air volume, break through the limitation of the traditional electric hair dryer which can only be coarsely adjusted by 2-3 mechanical buttons, and provide a better use experience for the user.

[0031] Specifically, as shown in Figure 3 The outer side of the control circuit board 61 is provided with a power supply structure 7. The power supply structure 7 includes a storage battery 71 arranged in the handheld shell 1. The storage battery 71 is electrically connected with the control circuit board 61.

[0032] Specifically, as shown in Figure 3 The front side of the top of the control circuit board 61 is provided with a charging interface 72. The charging interface 72 is electrically connected with the storage battery 71.

[0033] Specifically, as shown in Figure 3 The front side and the rear side of the storage battery 71 are both provided with isolation pads 73. The isolation pads 73 are made of insulating materials.

[0034] In the embodiment, the storage battery 71 is arranged in the handheld shell 1 as an electric energy storage device and is electrically connected with the control circuit board 61, so as to provide an independent power source for the whole device. When in use, the storage battery 71 can supply power for the control circuit board 61, the blowing structure 5 and other components, so that they can work normally. The charging interface 72 is arranged on the front side of the top of the control circuit board 61 and is electrically connected with the storage battery 71, so that the user can charge the storage battery 71 through the interface, ensure the endurance of the device, and make the user not limited to the socket position like using the traditional plug-in electric hair dryer, so that the user can use it more flexibly and conveniently. In addition, the isolation pads 73 made of insulating materials arranged on the front side and the rear side of the storage battery 71 can effectively prevent the storage battery 71 from leaking electricity and avoid the safety hazard caused by the leakage of electricity, so as to protect the safety of the user.

[0035] Specifically, as shown in Figure 5 The blowing structure 5 includes a spiral support 51 fixedly connected to the inside of the inner shell 3. The inside of the casing 4 is provided with a motor 52. The output end of the motor 52 penetrates through the top of the spiral support 51.

[0036] Specifically, as shown in Figure 5As shown, the output end of the motor 52 is plugged with the fan blade 53, which is located inside the inner shell 3.

[0037] In this embodiment: by setting the blowing structure 5, the inner shell 3 is fixedly connected with the spiral support 51 inside, which provides stable support for the motor 52. The motor 52, as a power source, has its output end penetrating the top of the spiral support 51 and being plugged with the fan blade 53, which is located inside the inner shell 3. When the motor 52 starts, the motor 52 drives the fan blade 53 to rotate to generate airflow, thereby realizing the blowing function. This structural layout makes the generation of airflow more stable and efficient. Meanwhile, the existence of the inner shell 3 can protect and support the motor 52 and the fan blade 53 to some extent, which helps to prolong the service life of the equipment.

[0038] Specifically, as shown in the figure, Figure 4 The outer side of the concave-convex block 8 is in contact with the inner side of the gear sleeve 64.

[0039] Specifically, as shown in the figure, Figure 5 The bottom of the inner shell 3 is clamped with the protective net 9, which is located at the bottom of the fan blade 53 and at the bottom side inside the outer shell 2.

[0040] In this embodiment: by setting the concave-convex block 8 and the protective net 9, the concave-convex block 8 fixedly connected to the top of the outer shell 4 has its outer side in contact with the inner side of the gear sleeve 64, which can enhance the friction and stability between the gear sleeve 64 and the outer shell 4, ensuring that the gear sleeve 64 will not slip or shift when rotating, and ensuring the normal operation of the air volume adjusting mechanism 6. In addition, the protective net 9 is arranged at the bottom of the inner shell 3, at the bottom of the fan blade 53 and at the bottom side inside the outer shell 2, which can prevent foreign matters from entering the inner shell 3 and avoid damage to the fan blade 53 and the motor 52 caused by foreign matters, ensuring normal operation.

[0041] Working principle: during the use of the adjustable air volume electric hair dryer, first, press the start button 62, the control circuit board 61 arranged in the handheld shell 1 receives the signal, and the blowing structure 5 is started. In the blowing structure 5, the spiral support 51 fixedly connected in the inner shell 3 provides stable support for the motor 52 in the machine shell 4. The output end of the motor 52 penetrates the top of the spiral support 51 and is inserted into the fan blade 53. The motor 52 drives the fan blade 53 to rotate to generate airflow, realizes the blowing function, and the inner shell 3 plays a certain protection and support role for the motor 52 and the fan blade 53, which is helpful to prolong the service life of the equipment. If you need to adjust the air volume, rotate the rotating ring 65, which drives the gear sleeve 64 connected therewith to rotate. Because the gear sleeve 64 is engaged with the air volume adjusting gear 63, the air volume adjusting gear 63 is driven to rotate. The rotating information is transmitted to the control circuit board 61, and the control circuit board 61 adjusts the power or rotating speed of the motor 52 and other parameters accordingly, realizes flexible and accurate adjustment of the air volume, breaks through the limitation of traditional rough adjustment, and provides users with high-quality experience. In terms of power supply, the battery 71 in the handheld shell 1 is electrically connected with the control circuit board 61 and is used as an electric energy storage device to supply power to the whole equipment, so as to ensure the normal work of the control circuit board 61, the motor 52 and other components. The charging interface 72 on the top front side of the control circuit board 61 is connected with the battery 71, which is convenient for users to charge and ensures the endurance of the equipment, breaks away from the position limitation of the socket, and the insulating isolation pad 73 on the front and back sides of the battery 71 prevents electric leakage and ensures the safety of users.

[0042] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
