DETAILED DESCRIPTION

[0018] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 8 A rotatable high-speed hair dryer with side air intake includes a main body 1 and a battery unit 2. A motor 3 is provided inside the main body 1, and the motor 3 is electrically connected to the battery unit 2 through a wire. The battery unit 2 supplies power to the motor 3. A side air inlet 4 is provided on the outer peripheral surface of the main body 1. The main body 1 is rotatably connected to the battery unit 2. When the main body 1 and the battery unit 2 rotate relative to each other, the main body 1 and the battery unit 2 form an angle, and the angle can reach 90°.

[0020] Preferably, the main body 1 includes a main housing 5, the motor 3 is disposed within the main housing 5, an air outlet hood 6 is disposed at one end of the main housing 5, and an air inlet hood 7 is disposed at the other end of the main housing 5. The side air inlet 4 is located on the side wall of the air inlet hood 7, the side air inlet 4 is connected to the interior of the air inlet hood 7 and the interior of the main housing 5, and the interior of the air outlet hood 6 is connected to the interior of the main housing 5. A filter (not shown) is disposed inside the air inlet hood 7 to filter dust and foreign matter entering the air through the side air inlet 4. The filter corresponding to the position of the side air inlet 4 is recessed inward. In this way, when foreign matter such as leaves or plastic bags are forcefully attracted to the air inlet hood 7, since the filter and the side air inlet 4 are not in the same plane, these foreign matter are less likely to completely block the recessed filter, leaving a partial air intake channel for continued air intake and providing partial protection for the motor.

[0021] Different from the front and rear air intake of traditional hair dryers, the rotatable high-speed hair dryer with side air intake of the present invention adopts the side air intake method, which facilitates the rotation connection between the main body 1 and the battery part 2.

[0022] Preferably, a connecting shell 8 is provided at one end of the battery unit 2, and the battery unit 2 is detachably mounted on the connecting shell 8. One end face of the connecting shell 8 is a first inclined surface 9, on which a rotating shaft 10 is obliquely provided, and the inclination angle of the rotating shaft 10 is 45°. A second inclined surface 11 is provided at one end of the air inlet cover 7, and the second inclined surface 11 is parallel to and matched with the first inclined surface 9. A rotating shaft socket 12 is provided on the second inclined surface 11, and a rotating shaft hole 13 is obliquely provided on the rotating shaft socket 12. The rotating shaft hole 13 matches the rotating shaft 10, and the rotating shaft 10 is rotatably inserted into the rotating shaft hole 13. The second inclined surface 11, the first inclined surface 9, the obliquely provided rotating shaft 10, and the rotating shaft hole 13 form a certain angle between the main body 1 and the battery unit 2 when the rotating shaft 10 rotates in the rotating shaft hole 13, so that the main body 1 can be bent at a certain angle for operation.

[0023] A button paddle 23 and a button slider 24 are provided on the connecting shell 8. The button paddle 23 is fixedly connected to the button slider 24. A spring 25 is provided between one end of the button slider 24 and one end of the battery part. Two axially extending columns (not marked in the figure) are provided at the other end of the button slider 24. Two axial holes are provided on the second inclined surface 11 of the air inlet cover 7. The two columns correspond to the two axial holes. When the two columns are inserted into the two axial holes, the main body 1 and the battery part 2 cannot rotate relative to each other.

[0024] Preferably, the inclination angles of the first inclined surface 9 and the second inclined surface 11 are 30°-45°.

[0025] Preferably, the outlet end of the motor 3 is close to the outlet cover 6. A guide cover 14 is provided at this outlet end of the motor 3. The guide cover 14 is a conical cover. The larger end of the guide cover 14 is mounted on the outlet end of the motor 3. The smaller end of the guide cover 14 is provided with a round through hole 15. The guide cover 14 not only protects the motor but also guides the air flow, reducing air resistance and noise during operation of the high-speed hair dryer.

[0026] When the rotatable high-speed hair dryer with side air intake of the present invention is in use, when the second inclined surface 11 is completely aligned with the first inclined surface 9, the main body 1 and the battery part 2 are in a straight line (such as Figure 7 As shown), the motor starts, and the outside air enters the air inlet 7 and the main housing 5 from the side air inlet 4. The airflow passes through the guide cover 14 and then enters the air outlet 6, and flows out from the air outlet 6. It can blow air to some objects that need to be blown. When there are some usage scenarios, such as some corners, the main body 1 and the battery part 2 in a straight state are difficult to reach, and the main body 1 and the battery part 2 need to be rotated to a certain angle, then the button paddle 23 is turned to drive the button slider 24 to slide axially, so that the two columns are disengaged from the two shaft holes, and one of the main body 1 and the battery part 2 is rotated, and the shaft 10 rotates in the shaft hole 13, and the main body 1 and the battery part 2 can rotate relative to each other, so that a certain angle is formed between the main body 1 and the battery part 2 (such as Figure 8 As shown), it can be used for blowing in some usage scenarios.

[0027] Preferably, a cylindrical wind guide cover 16 is provided at the other end of the air inlet cover 7, and the wind guide cover 16 covers the motor 3 in the main housing 5. The two ends of the wind guide cover 16 are open, and the air flow can pass through the wind guide cover 16. The wind guide cover 16 can guide the wind entering from the side air inlet 4 to make the air flow smooth, solve the problem of wind whistling of high-speed airflow, and greatly reduce the noise of the high-speed hair dryer when it is working.

[0028] Preferably, a wire groove 17 is provided between the outer wall of the air guide cover 16 and the inner wall of the main housing 5, and part of the wires outside the motor 3 are located in the wire groove 17 to avoid exposure of the wires. Friction will be generated between the exposed wires and the high-speed airflow, which will block the airflow to a certain extent and generate noise. Hiding the wires in the wire groove 17 can also reduce the noise when the high-speed hair dryer is working.

[0029] By using the above-mentioned multiple noise reduction measures together, the noise of high-speed hair dryers during operation can be greatly reduced, improving the consumer experience.

[0030] Preferably, one end of the battery unit 2 is provided with a plug 18 for conducting electricity, so that after the battery unit 2 is removed separately, it can be conductively connected to other electrical products through the plug 18, thereby expanding the application range of the battery.

[0031] Preferably, a buckle 19 is provided at one end of the battery part 2, and a slot 20 is provided on the connecting shell 8. The buckle 19 is stuck in the slot 20, and the connection or removal of the connecting shell 8 and the battery part 2 is very convenient.

[0032] Preferably, the other end of the battery unit 2 is provided with a plurality of anti-roll feet 21, two of which are provided with mounting holes 22. When the high-speed hair dryer is not in use, the plurality of anti-roll feet 21 can prevent the hair dryer from rolling on the ground. The two mounting holes 22 are used to attach a hand strap to the hair dryer, allowing the user to put it on their hand for convenient use.

[0033] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
