[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1: As Figures 1-10 shown, the portable and reliable swing cycle air supply hair dryer includes a frame 1, an air duct group 2 and a hot air assembly 3. The air duct group 2 includes an air outlet duct 201 that can reciprocally swing relative to the frame 1. The air outlet duct 201 is strip-shaped and has an air outlet channel 202 extending along its length direction. On the side of the air outlet duct 201 facing away from the frame 1, a plurality of air outlet openings 203 communicating with the air outlet channel 202 are provided. The plurality of air outlet openings 203 are spaced apart in the length direction of the air outlet duct 201. The hot air assembly 3 is disposed in the air duct group 2 for supplying air to the air outlet channel 202. The frame 1 has a connecting rod group 102 extending up and down, and the air outlet duct 201 can swing left and right relative to the frame 1 and deviate from the connecting rod group 102.

[0032] When using this portable and reliable swing cycle air supply hair dryer to dry hair, the user stands or sits on one side of the air outlet duct 201, and the air outlet duct 201 swings left and right reciprocally and the air outlet openings 203 blow air. Since the air outlet duct 201 covers the user's hair surface when swinging left and right reciprocally, the user's hair can be dried by the left and right reciprocal swing of the air outlet duct 201 and the blowing of the air outlet openings 203.

[0033] In summary, this embodiment provides a portable and reliable swing cycle air supply hair dryer to solve the problem that the existing hair dryer is equipped with multiple air ducts that blow air through corresponding air outlet openings in the hair drying hood, the air ducts in the hair drying hood are complex, and the overall volume of the hair dryer is huge. The main solution is to configure an air outlet duct 201 on the frame 1 that can reciprocally swing left and right relative to it. The air outlet duct 201 is configured to be strip-shaped and has an air outlet channel 202 extending along its length direction and a plurality of air outlet openings 203 communicating with the air outlet channel 202. The plurality of air outlet openings 203 are arranged on the side of the air outlet duct 201 facing away from the frame 1 and are spaced apart in the length direction of the air outlet duct 201, so that when the air outlet duct 201 swings left and right reciprocally, it can cover the user's hair surface and blow the user's hair surface. By adopting a single air duct with multiple air outlet openings, the air duct structure is simple and the overall volume of the hair dryer is small.

[0034] In Embodiment 1 of the present invention, the air duct group 2 further includes an air inlet duct 204 extending forward and backward. The air inlet duct 204 is rotatably connected to the frame 1 and connected to the air outlet duct 201. At least part of the air outlet duct 201 is arranged at an angle with the air inlet duct 204. A power mechanism 4 is provided on the frame 1. The air inlet duct 204 is driven by the power mechanism 4 to reciprocally rotate around the axis of the air inlet duct 204. When the air inlet duct 204 rotates, it drives the air outlet duct 201 to swing. The above arrangement, by configuring the air inlet duct 204 and the power mechanism 4 on the frame 1, with the air inlet duct 204 extending forward and backward and being driven by the power mechanism 4 to rotate around the axis of the air inlet duct 204, and the air outlet duct 201 being connected to the air inlet duct 204 and at least part of it being arranged at an angle with the air inlet duct 204, enables the air outlet duct 201 to be driven to swing and blow the hair surface when the air inlet duct 204 rotates.

[0035] In Embodiment 1 of the present invention, the power mechanism 4 includes a first motor 401, a driving gear 402 and a driven gear 403. The first motor 401 is provided on the frame 1. The driven gear 403 is sleeved on the air inlet duct 204. The driving gear 402 is provided on the output shaft of the first motor 401 and meshes with the driven gear 403. The above arrangement, by configuring the power mechanism 4 as the driven gear 403 sleeved on the air inlet duct 204, the driving gear 402 meshing with the driven gear 403 and the first motor 401 driving the driving gear 402 to rotate, enables the power mechanism 4 to drive the air inlet duct 204 to swing, and the driving structure is simple and easy to implement.

[0036] In Embodiment 1 of the present invention, the air outlet duct 201 includes a lower air outlet duct 205 and an upper air outlet duct 206. The lower air outlet duct 205 is arranged at the front end of the air inlet duct 204 and at an angle with the air inlet duct 204. The upper air outlet duct 206 extends forward from the upper end of the lower air outlet duct 205. The lower air outlet duct 205 and the upper air outlet duct 206 are smoothly transitioned to form an arc-shaped duct 207. Specifically, the lower air outlet duct 205 and the upper air outlet duct 206 are perpendicular to each other, and the lower air outlet duct 205 and the air inlet duct 204 are perpendicular to each other. The above arrangement, by configuring the air outlet duct 201 as the lower air outlet duct 205 and the upper air outlet duct 206, makes the air outlet duct 201 in an L shape, which adapts to the shape of the user's head. When the air outlet duct 201 rotates, it can cover most of the hair surface, and the hair drying effect is good.

[0037] In Embodiment 1 of the present invention, the lower air outlet pipe 205 has a lower air outlet nozzle 208, and the upper air outlet pipe 206 has an upper air outlet nozzle 209. The upper air outlet nozzle 209 is inclined backward from top to bottom, and the lower air outlet nozzle 208 is inclined forward from top to bottom. The air outlet ends of the lower air outlet nozzle 208 and the upper air outlet nozzle 209 form a plurality of air outlets 203. The above setting configures the upper air outlet nozzle 209 to be inclined backward from top to bottom, so that the upper air outlet nozzle 209 blows air backward and downward to blow the hair in front of the user's forehead, preventing the hair in front of the user's forehead from floating forward to cover the user's face and affecting the comfort of hair drying. At the same time, by configuring the lower air outlet nozzle 208 to be inclined forward from top to bottom, the lower air outlet nozzle 208 blows air forward and downward to blow the hair, preventing the hair at the back end of the user from floating backward and winding around the rack 1, affecting the comfort of hair drying.

[0038] In Embodiment 1 of the present invention, there are a plurality of upper air outlet nozzles 209, and the plurality of upper air outlet nozzles 209 are spaced apart in the length direction of the upper air outlet pipe 206. The angle between the plurality of upper air outlet nozzles 209 and the horizontal plane gradually decreases in the direction away from the lower air outlet pipe 205. The above setting configures the angle between the plurality of upper air outlet nozzles 209 and the horizontal plane to gradually decrease in the direction away from the lower air outlet pipe 205, so that the effect of the plurality of upper air outlet nozzles 209 blowing air backward gradually weakens from front to back, enabling the plurality of upper air outlet nozzles 209 to blow the hair in front of the user's forehead backward and also blow the hair at the back of the user's head downward, with an overall good blowing effect.

[0039] In Embodiment 1 of the present invention, among the plurality of upper air outlet nozzles 209, the frontmost upper air outlet nozzle 209 is in the shape of a flat cylinder, and the remaining upper air outlet nozzles 209 are in the shape of a cylinder. The above setting configures the frontmost upper air outlet nozzle 209 to be in the shape of a flat cylinder, so that the frontmost upper air outlet nozzle 209 has a good blowing effect backward.

[0040] In Embodiment 1 of the present invention, there are a plurality of lower air outlet nozzles 208, and the plurality of lower air outlet nozzles 208 are spaced apart in the length direction of the lower air outlet pipe 205. Among the plurality of lower air outlet nozzles 208, the upper lower air outlet nozzles 208 are in the shape of a flat cylinder, and the lower lower air outlet nozzles 208 are in the shape of a cylinder. The above setting configures the plurality of lower air outlet nozzles 208 such that the upper lower air outlet nozzles 208 are in the shape of a flat cylinder and the lower lower air outlet nozzles 208 are in the shape of a cylinder, making the configuration of the plurality of lower air outlet nozzles 208 reasonable and having a good blowing effect forward and downward.

[0041] In Embodiment 1 of the present invention, the air outlet pipe 201 is externally covered with a housing 200 that fits its shape and exposes a plurality of air outlets 203.

[0042] In Embodiment 1 of the present invention, the angle between the air outlet pipe 201 and the axis of the connecting rod group 102 is defined as the swing angle. The value range of the swing angle when the air outlet pipe 201 swings to the left is: 0° to 45°, and the value range of the swing angle when the air outlet pipe 201 swings to the right is: 0° to 45°.

[0043] In Embodiment 1 of the present invention, the air inlet pipe 204 has an air inlet passage 210 and an air inlet 211. The air inlet 211 and the air outlet 203 are opposite to each other front and back. The air inlet 211 is at the rear and the air outlet 203 is at the front. The air outlet pipe 201 is arranged at the front end of the air inlet pipe 204 and is communicated with the air inlet pipe 204. The air inlet passage 210 is communicated with the air outlet passage 202. The hot air assembly 3 is accommodated in the air inlet passage 210 and is detachably and fixedly connected to the air inlet pipe 204. An external air source member 6 for connecting an external air duct is arranged on one side of the air inlet 211.

[0044] The portable and reliable swing cycle air supply hair dryer has the following two usage modes:

[0045] Mode 1: The hot air assembly 3 is assembled in the air inlet passage 210. The hot air assembly 3 drives the gas to flow along the air inlet passage 210 from the air inlet 211 to the air outlet 203 to realize hair drying.

[0046] Mode 2: The hot air assembly 3 is detached from the air inlet passage 210. A household or commercial air duct is connected to the air inlet pipe 204 through the external air source member 6. The household or commercial air duct drives the gas to flow along the air inlet passage 210 from the air inlet 211 to the air outlet 203 to realize hair drying.

[0047] In summary, through the above settings, by configuring the hot air assembly 3 detachably and fixedly connected to the air inlet pipe 204 in the air inlet passage 210 and configuring the external air source member 6 for connecting an external air duct on one side of the air inlet 211, the portable and reliable swing cycle air supply hair dryer has multiple usage modes. Users can replace the air source according to their needs, and it is convenient to use, has good adaptability and is easy to repair.

[0048] In Embodiment 1 of the present invention, the outer wall of the hot air assembly 3 is closely attached to the inner wall of the air inlet passage 210. The hot air assembly 3 can move along the air inlet passage 210. A stop member 212 is arranged on the inner wall of the air inlet passage 210. The stop member 212 abuts against the hot air assembly 3 front and back to limit the forward movement of the hot air assembly 3. Among them, the hot air assembly 3 is inserted into the air inlet passage 210 from the air inlet 211 and can move along the air inlet passage 210. Through the above settings, by configuring the stop member 212 on the inner wall of the air inlet passage 210 that abuts against the hot air assembly 3 front and back to limit the forward movement of the hot air assembly 3, it is avoided that the hot air assembly 3 is inserted too far into the air inlet passage 210 and is difficult to pull out.

[0049] In Embodiment 1 of the present invention, a protective cover 5 covering the air inlet 211 is arranged on the air inlet pipe 204. The protective cover 5 is detachably and fixedly connected to the air inlet pipe 204 and has a suction hole 501 communicated with the air inlet passage 210. Through the above settings, by configuring the protective cover 5 covering the air inlet 211 on the air inlet pipe 204, it is avoided that when the user is in Usage Mode 1, the motor is accidentally touched, causing danger.

[0050] In Embodiment 1 of the present invention, the external air source member 6 is a magnetic member extending circumferentially along the air inlet 211. When the user uses Mode 2, the hair dryer is magnetically attracted to the external air source member 6, and the connection is simple and fast.

[0051] In an embodiment of the present invention, the external air source member 6 is provided on the outer wall of the air duct group 2. When the hair dryer is magnetically attracted to the external air source member 6, it is sleeved outside the air inlet pipe 204.
