Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to a detour air guide assembly and a hair dryer. Background Art

[0002] With the development of the economy and the improvement of people's living standards, people's requirements for the quality of life are getting higher and higher, making hair dryers gradually become essential items for most families. In the prior art, the structural design of the air guide assembly of the hair dryer is not reasonable, resulting in a relatively large structure of the main body of the hair dryer, which is inconvenient for storage and carrying. At the same time, it also causes the air outlet of the hair dryer to be uneven and not strong, resulting in a poor user experience. Content of the Utility Model

[0003] Based on this, in view of the problem of unreasonable structural design of the air guide assembly of the hair dryer, it is necessary to provide a detour air guide assembly and a hair dryer.

[0004] A detour air guide assembly for a hair dryer, the detour air guide assembly comprising: a front shell assembly provided with a receiving cavity and an air outlet, the receiving cavity communicating with the air outlet; a rear cover assembly disposed on the front shell assembly, the rear cover assembly being provided with an air inlet and a first flow channel, the air inlet communicating with the first flow channel, the rear cover assembly being provided with a second arc-shaped channel located outside the first flow channel; a bracket fixing sleeve disposed in the receiving cavity on the front shell assembly, a third flow channel being formed between the bracket fixing sleeve and the front shell assembly, the bracket fixing sleeve being provided with a first arc-shaped channel, the rear cover assembly extending to the first arc-shaped channel, a second flow channel being formed between the bracket fixing sleeve and the rear cover assembly, and the air inlet, the first flow channel, the first arc-shaped channel, the second flow channel, the second arc-shaped channel, the third flow channel and the air outlet being sequentially communicated.

[0005] The present application discloses a detour air guiding assembly for a hair dryer. By providing a receiving cavity in the front shell assembly, the rear cover assembly and the bracket fixing sleeve can be placed inside, enabling the various components of the hair dryer to be compactly combined together, reducing the overall volume, facilitating handheld operation, and being more conducive to storage and portability. At the same time, it protects the assembly from external dust, moisture, and physical collisions, extending its service life. The front shell assembly, the rear cover assembly, and the bracket fixing sleeve are combined to form a detour air guiding assembly. In the structure of this detour air guiding assembly, the outside air first enters from the air inlet provided in the rear cover assembly and passes through the first flow channel. Since the first flow channel is designed relatively wide, it can accommodate the outside air entering to the greatest extent, increasing the air intake volume. After passing through the first flow channel, due to the first arc-shaped channel provided in the bracket fixing sleeve, the direction of the outside air is changed, and the outside air is returned to the second flow channel. Since the second flow channel is designed relatively narrow, it can well increase the pressure of the outside air, increasing the wind speed to a certain extent. After passing through the second flow channel, it reaches the second arc-shaped channel provided in the rear cover assembly. The second arc-shaped channel changes the flow direction of the outside air again, guiding the outside air to the third flow channel provided in the front shell assembly. The third flow channel is also designed relatively narrow, increasing the wind pressure again, and delivering the air to the air outlet, finally completing the blowing function of the hair dryer. This design of the detour air guiding assembly compresses and accelerates the air in a limited space, thereby increasing the blowing speed and air volume, enabling the motor of the hair dryer to more effectively convert energy into wind energy, improving the energy utilization efficiency, thus obtaining a better blowing effect under the same power input. At the same time, it can make the blown wind energy more evenly distributed, avoiding the situation of excessive or too small local wind force. Moreover, the detour air duct can play a certain buffering and sound-absorbing role on the air flow, reducing the noise generated by air flow. The design of the detour air guiding assembly can minimize the volume of the hair dryer, facilitating daily storage and portability when going out, meeting the actual needs of users, and improving the market competitiveness to a certain extent.

[0006] In one embodiment, the second arc-shaped channel is arranged to surround the first flow channel. By arranging the second arc-shaped channel to surround the first flow channel, the structure of the detour air guiding assembly is made more complete, ensuring that the air flow can change direction in all directions from the second arc-shaped channel, guiding the air flow to turn correctly in the predetermined direction, and achieving precise control of the air flow direction.

[0007] In one embodiment, the third flow channel is arranged to surround the first arc-shaped channel. By arranging the third flow channel to surround the first arc-shaped channel, the structure of the detour air guiding assembly is made more complete, ensuring that the air flow can be blown out from the third flow channel in all directions and more evenly towards the user, enabling the user to dry their hair faster and ensuring that the user can better experience this hair dryer.

[0008] In one embodiment, the bracket fixing sleeve is provided with a recessed groove, the rear cover assembly extends to the recessed groove, the bottom of the recessed groove forms the first arc-shaped channel, and the second flow channel is formed between the rear cover assembly and the side wall of the recessed groove. By forming the first arc-shaped channel at the bottom of the recessed groove provided on the bracket fixing sleeve, it is ensured that the airflow realizes the first turning, and the arc-shaped design helps to reduce the pressure loss during the flow process and improve the utilization rate of the airflow. The side wall of the recessed groove and the rear cover assembly form the second flow channel, which provides space for the subsequent flow of the airflow and ensures the continuity of the airflow. At the same time, the second flow channel also realizes the function of pressurizing the airflow, ensuring the normal use of the hair dryer.

[0009] In one embodiment, the rear cover assembly is provided with a guide groove surrounding the first flow channel, the bottom of the guide groove forms the second arc-shaped channel, part of the bracket fixing sleeve extends into the guide groove, and the second flow channel is formed between one side of the bracket fixing sleeve and the side wall of the guide groove close to the first flow channel. By providing the guide groove surrounding the first flow channel in the rear cover assembly and forming the second arc-shaped channel at the bottom of the guide groove, the second turning of the airflow is achieved, and the airflow is guided to the direction in which it is finally required to be blown out. At the same time, the arc-shaped design helps to reduce the pressure loss during the flow process and improve the utilization rate of the airflow. Part of the bracket fixing sleeve extends into the guide groove, providing a preliminary guiding direction for the airflow. At the same time, the second flow channel is formed between one side of the bracket fixing sleeve and the side wall of the guide groove close to the first flow channel, so that the guide channel of the detour air guide assembly is more complete and connected, ensuring that the airflow can pass through or bypass these specific areas more smoothly, and realizing the basic function of the hair dryer.

[0010] In one embodiment, the third flow channel is formed between the other side of the bracket fixing sleeve and the front shell component and / or the rear cover component. By forming the third flow channel between the other side of the bracket fixing sleeve and the front shell component and / or the rear cover component, the airflow is pressurized for the last time, so that the airflow can be blown to the user more efficiently and powerfully, and the internal space of the hair dryer is effectively used to realize the layout of the flow channel, and the overall structure is more compact and complete, thereby improving the market competitiveness of the hair dryer.

[0011] In one embodiment, the bracket fixing sleeve includes an inner liner and an outer cylinder sleeve. The inner liner is disposed on the outer cylinder sleeve and is located inside the outer cylinder sleeve. One end of the inner liner is arc-shaped, and the first arc-shaped channel is provided at one end of the arc-shaped portion. The outer cylinder sleeve and the rear cover assembly form the second flow channel, and the outer cylinder sleeve and the inner side wall of the front shell assembly form the third flow channel. By disposing the inner liner inside the outer cylinder sleeve, a circuitous air guiding assembly can be better formed, which helps to guide the gas to flow more smoothly, increases the wind speed and air volume, and achieves a more efficient blowing effect. At the same time, disposing the inner liner inside the outer cylinder sleeve can make the inner liner more stable, reducing the possibility of damage to the inner liner caused by vibration or shaking during the operation of the hair dryer. Since one end of the inner liner is arranged in an arc shape, the first arc-shaped channel can be better formed, thereby reducing the resistance in the channel, increasing the wind speed and air volume, and reducing losses. In addition, the arc-shaped structure is relatively stable, capable of withstanding a certain amount of internal pressure and external impact, increasing the overall stability of the inner liner. At the same time, the arc-shaped channel is not prone to dust accumulation, facilitating cleaning and maintenance, and ensuring the unobstructedness of the circuitous air guiding assembly. Since the outer cylinder sleeve and the rear cover assembly form the second flow channel, and the structure of the second flow channel is relatively narrow, the wind speed can be increased, the diffusion of the air flow in the channel and the loss of energy can be reduced, improving the energy utilization rate. At the same time, it also helps to make the passing air flow more stable and concentrated, reducing the disorder and fluctuation of the air flow. In combination with the third flow channel formed by the outer cylinder sleeve and the front shell assembly, the wind pressure is further enhanced, further increasing the wind speed and wind force, while improving the working stability of the hair dryer, meeting the user's demand for hairstyle design, and enhancing the user experience.

[0012] In one embodiment, one end of the inner container is provided with a plurality of second buckles. The second buckles are arranged along the circumferential direction of one end of the inner container. The front shell assembly is provided with a plurality of second card holes. The plurality of second buckles are clamped in the plurality of second card holes. The front shell assembly is provided with an inner groove, and one end of the outer cylinder sleeve is arranged in the inner groove. By providing a plurality of second buckles at the other end of the inner container and arranging the plurality of second buckles around one end of the inner container, and at the same time, the front shell assembly is provided with a plurality of second card holes which are also arranged around the front shell assembly, and arranging the plurality of second buckles in the plurality of second card holes one by one, the inner container can be clamped inside the front shell assembly in all directions. The stable clamping can effectively reduce the noise and vibration generated during the operation of the inner container, so that the inner container will not be displaced or loosened due to the impact of the high-speed rotating motor and the airflow during the operation of the hair dryer, reducing the possibility of failure or danger caused by the shaking of the bracket fixing sleeve. Arranging one end of the outer cylinder sleeve in the inner groove provided in the front shell assembly can make the bracket fixing sleeve and the front shell assembly be more firmly combined together, enhancing the structural stability of the whole hair dryer. The long-term stable fixation helps to extend the service life of the hair dryer. At the same time, the design of the inner groove helps to improve the sealing performance between the front shell assembly and the bracket fixing sleeve, reducing air leakage, thereby improving the performance and efficiency of the hair dryer.

[0013] In one embodiment, the rear cover assembly includes an arc member and a cylindrical member. The arc member is arranged on the cylindrical member and surrounds the outside of the cylindrical member. The arc member is provided with the second arc-shaped channel. One end of the cylindrical member is provided with the air inlet. The first flow channel is arranged inside the cylindrical member. Part of the cylindrical member is located in the accommodating cavity. By arranging the arc member outside the cylindrical member, the stability of the cylindrical member is increased, ensuring that the cylindrical member can stably intake and supply air. By arranging the second arc-shaped channel in the arc member, the airflow direction can be changed again, so that the airflow can return to the correct blowing direction again. Combining with the design of the first arc-shaped channel, the air duct of the hair dryer can be minimized, making efficient use of the internal space of the hair dryer, enabling the internal components of the hair dryer to be arranged more closely, and reducing the need for a straight-line length air duct. Since the cylindrical member is provided with an air inlet and a first flow channel and the cylindrical member is located in the accommodating cavity provided in the front shell assembly, a wind source is provided for the internal detour air guiding assembly of the hair dryer. At the same time, since the space of the first flow channel is larger than that of the second flow channel and the third flow channel, more airflow can be provided and guided into the internal detour air guiding assembly, thus ensuring the stable operation of the hair dryer.

[0014] In one embodiment, the arc-shaped member is provided with a plurality of first buckles. The first buckles are arranged along the arc-shaped member. The front shell assembly is provided with a plurality of first card holes. The number of the first card holes is also a plurality. The plurality of first buckles are correspondingly arranged on the plurality of first card holes. By providing a plurality of first buckles on the arc-shaped member and arranging the plurality of first buckles around the arc-shaped member, and at the same time, the front shell assembly is provided with a plurality of first card holes, and the plurality of first buckles are respectively and correspondingly matched with the plurality of first card holes. The distribution of the plurality of buckles can increase the connection points between the arc-shaped member and the front shell assembly, thereby improving the strength and stability of the entire structure, realizing the stable connection between the rear cover assembly and the front shell assembly, and ensuring that the rear cover assembly will not loosen or fall off during use, maintaining the stable working state of the hair dryer. Through the design of the buckles, the rear cover assembly and the front shell assembly can be conveniently assembled or disassembled, which helps to improve the assembly efficiency during the production and manufacturing process and is also convenient for users to disassemble and clean when needed.

[0015] In one embodiment, the arc-shaped member is further provided with a plurality of limiting blocks. The limiting blocks are arranged along the arc-shaped member and are located beside the first buckles. The plurality of limiting blocks abut against the front shell assembly. By providing a plurality of limiting blocks on the arc-shaped member, arranging the plurality of limiting blocks around the arc-shaped member and beside the first buckles, and abutting the plurality of limiting blocks against the front shell assembly, it can help the arc-shaped member and the front shell assembly to be correctly positioned during assembly, ensure the accurate relative positions between the components. The limiting blocks can limit the installation of the front shell assembly within a certain range, preventing the front shell assembly from shifting or rotating during the operation of the hair dryer and affecting normal use. When the hair dryer is subjected to external forces, the limiting blocks can disperse the force to multiple positions, to a certain extent, reducing the local stress and the risk of damage.

[0016] In one embodiment, it further includes a plurality of brackets. The plurality of brackets are arranged along the side wall of the bracket fixing sleeve. The bracket fixing sleeve is provided with a plurality of installation grooves. The number of the installation grooves is also a plurality and they are arranged along the bracket fixing sleeve. The plurality of brackets are correspondingly clamped in the plurality of installation grooves. By providing a plurality of installation grooves on the bracket fixing sleeve and arranging them around the bracket fixing sleeve, and at the same time clamping the plurality of brackets in the plurality of installation grooves, a storage position is provided for the brackets, ensuring that the brackets remain stable at the designated positions, capable of jointly bearing external forces and vibrations, not easily moving or misaligning, which plays a crucial role in maintaining the integrity and stability of the internal structure of the hair dryer. At the same time, the clamping mechanism can make the assembly of the hair dryer faster and more efficient, improving the production efficiency, and the simple connection method reduces the production cost.

[0017] In one embodiment, it further includes a heating wire. The bracket is provided with a plurality of heating wire slots, and the heating wire is arranged on the plurality of heating wire slots and located in the third flow channel. The heating wire is arranged along the plurality of brackets. By providing a plurality of heating wire slots on the bracket, support is provided for the heating wire. At the same time, the heating wire is arranged around the slots and located in the third flow channel, so that the heating wire can be evenly distributed, the contact area between the heating wire and the air in the third flow channel can be increased, good heat conduction can be ensured and the heating efficiency can be improved, enabling the hair dryer to blow out hot air faster and ensuring that the hair dryer can blow out hot air evenly, enhancing the user experience and satisfaction. At the same time, this design can fix the heating wire more stably on the bracket, preventing the heating wire from shaking or shifting during use, thereby prolonging the service life of the heating wire. Moreover, when the heating wire fails, only the heating wire needs to be replaced, without replacing the entire bracket, reducing the maintenance cost.

[0018] In one embodiment, it further includes a heat insulation sleeve. The heat insulation sleeve is arranged on the bracket and along the length direction of the plurality of brackets, and the heat insulation sleeve is arranged opposite to the heating wire. By arranging the heat insulation sleeve around the bracket and opposite to the heating wire, it can prevent users from contacting the high temperature generated by the heating wire or directly contacting the heating wire and getting burned when using the hair dryer to blow out hot air, reducing the risk of burns or other safety accidents caused by accidental contact with high temperature, and playing a role in protecting users. At the same time, the setting of the heat insulation sleeve can also prevent other components inside the hair dryer, such as electronic components, from being damaged or aged due to the high temperature generated by the heating wire, prolonging their service life. The heat insulation sleeve also helps to keep the temperature environment around the heating wire relatively stable, reducing the influence of external factors on the working temperature of the heating wire, and can reduce unnecessary heat dissipation to the outside, thereby ensuring the stable performance of the hair dryer.

[0019] The second aspect of the present application discloses a hair dryer, which includes: the above-mentioned detour air guiding component; a fan, the fan is arranged in the detour air guiding component; a housing component, the housing component is provided with a component accommodation cavity, and the detour air guiding component is located in the component accommodation cavity; a handle component, the handle component is arranged on the housing component.

[0020] The hair dryer disclosed in the second aspect of the present application has a blower disposed in the circuitous air guiding assembly, which sucks in and propels the surrounding air, providing a stable air flow supply for the circuitous air guiding assembly, ensuring that the hair dryer can continuously blow air during use and meet the needs of users. Since the housing assembly is provided with an assembly accommodation cavity, it provides a storage location and stable support for the circuitous air guiding assembly, preventing this channel from being physically damaged by the outside world, such as collision, extrusion, etc., and extending its service life. At the same time, the complex circuitous air guiding assembly is hidden in this accommodation cavity, making the appearance of the hair dryer more concise and beautiful. Combining with the handle assembly being disposed on the housing assembly, the overall structure of the hair dryer is integrated and complete, allowing users to hold and control it when using the hair dryer. Coupled with the structure of the circuitous air guiding assembly making the overall volume of the hair dryer smaller, thus this hair dryer meets the actual usage requirements of users and enhances the market position of this hair dryer.

Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0037] The following describes some embodiments of the present invention with reference to the accompanying drawings, the detour air guiding assembly and the hair dryer.

[0038] Embodiment 1

[0039] As Figures 1 to 7 shown, this embodiment discloses a detour air guiding assembly and a hair dryer, including a front shell assembly 1.

The rear cover assembly 2 is provided with a second arc-shaped channel 203. The second arc-shaped channel 203 is located outside the first flow channel 202; a bracket fixing sleeve 3, the bracket fixing sleeve 3 is arranged on the front shell assembly 1 and is located in the receiving cavity. A third flow channel 101 is formed between the bracket fixing sleeve 3 and the front shell assembly 1. The bracket fixing sleeve 3 is provided with a first arc-shaped channel 301. The rear cover assembly 2 extends to the first arc-shaped channel 301. A second flow channel 302 is formed between the bracket fixing sleeve 3 and the rear cover assembly 2. The air inlet 201, the first flow channel 202, the first arc-shaped channel 301, the second flow channel 302, the second arc-shaped channel 203, the third flow channel 101 and the air outlet 102 are communicated in sequence.

[0040] The present application discloses a detour air guiding assembly for a hair dryer. By providing a receiving cavity in the front shell assembly 1, the rear cover assembly 2 and the bracket fixing sleeve 3 can be placed inside, enabling the various components of the hair dryer to be compactly combined together, reducing the overall volume, facilitating handheld operation, and being more conducive to storage and portability. At the same time, it protects the assembly from external dust, moisture, and physical collisions, extending its service life. Combining the front shell assembly 1, the rear cover assembly 2 and the bracket fixing sleeve 3 forms a detour air guiding assembly. In the structure of this detour air guiding assembly, the external air first enters from the air inlet 201 provided in the rear cover assembly 2 and passes through the first flow channel 202. Since the first flow channel 202 is designed relatively wide, it can accommodate the external air entering to the greatest extent, increasing the air intake volume. After passing through the first flow channel 202, due to the first arc-shaped channel 301 provided in the bracket fixing sleeve 3, the direction of the external air is changed, and the external air is returned to the second flow channel 302. Since the second flow channel 302 is designed relatively narrow, it can effectively increase the pressure of the external air, increasing the wind speed to a certain extent. After passing through the second flow channel 302, it reaches the second arc-shaped channel 203 provided in the rear cover assembly 2. The second arc-shaped channel 203 changes the flow direction of the external air again, guiding the external air to the third flow channel 101 provided in the front shell assembly 1. The third flow channel 101 is also designed relatively narrow, further increasing the wind pressure and delivering the air to the air outlet 102, finally completing the blowing function of the hair dryer. The design of this detour air guiding assembly compresses and accelerates the air in a limited space, thereby increasing the blowing speed and air volume, enabling the motor of the hair dryer to more effectively convert energy into wind energy, improving the energy utilization efficiency, thus obtaining a better blowing effect under the same power input. At the same time, it can make the blown wind energy more evenly distributed, avoiding the situation of excessive or too small local wind force. Moreover, the detour air duct can play a certain buffering and sound-absorbing role for the air flow, reducing the noise generated by air flow. The design of the detour air guiding assembly can minimize the volume of the hair dryer, facilitating daily storage and carrying when going out, meeting the actual needs of users, and improving the market competitiveness to a certain extent.

[0041] As Figure 2 shown, in addition to the features of the above embodiments, this embodiment further defines that: the second arc-shaped channel 203 is arranged around the first flow channel 202. By arranging the second arc-shaped channel 203 around the first flow channel 202, the structure of the detour air guiding assembly is made more complete, ensuring that the air flow can change direction in all directions from the second arc-shaped channel 203, guiding the air flow to turn correctly in the predetermined direction, and achieving precise control of the air flow direction.

[0042] As Figure 2As shown, in addition to the features of the above embodiments, this embodiment further defines that the third flow channel 101 is arranged around the first arc-shaped channel 301. By arranging the third flow channel 101 around the first arc-shaped channel 301, the structure of the detour air guiding component is made more complete, ensuring that the air flow can blow out from the third flow channel 101 in all directions and blow more evenly towards the user, enabling the user to dry their hair faster and ensuring that the user can better experience this hair dryer.

[0043] As Figure 2 , Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further defines that the bracket fixing sleeve 3 is provided with a concave groove, the rear cover assembly 2 extends to the concave groove, the bottom of the concave groove forms the first arc-shaped channel 301, and a second flow channel 302 is formed between the side wall of the concave groove and the rear cover assembly 2. By forming the first arc-shaped channel 301 at the bottom of the concave groove provided in the bracket fixing sleeve 3, it is ensured that the air flow makes the first turn, and at the same time, the arc design helps to reduce the pressure loss during the flow process, improve the utilization rate of the air flow, and the side wall of the concave groove and the rear cover assembly 2 form the second flow channel 302, providing space for the subsequent flow of the air flow, ensuring the continuity of the air flow, and at the same time, the second flow channel 302 also functions to pressurize the air flow, ensuring the normal use of the hair dryer.

[0044] As Figure 2 , Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further defines that the rear cover assembly 2 is provided with a guiding groove surrounding the first flow channel 202, the bottom of the guiding groove forms the second arc-shaped channel 203, a part of the bracket fixing sleeve 3 extends into the guiding groove, and a second flow channel 302 is formed between one side of the bracket fixing sleeve 3 and the side wall of the guiding groove close to the first flow channel 202. By providing a guiding groove surrounding the first flow channel 202 in the rear cover assembly 2 and forming the second arc-shaped channel 203 at the bottom of the guiding groove, the second turn of the air flow is achieved, guiding the air flow to the final direction where it needs to be blown out. At the same time, the arc design helps to reduce the pressure loss during the flow process and improve the utilization rate of the air flow. A part of the bracket fixing sleeve 3 extends into the guiding groove, providing a preliminary guiding direction for the air flow. At the same time, a second flow channel 302 is formed between one side of the bracket fixing sleeve 3 and the side wall of the guiding groove close to the first flow channel 202, making the guiding channels of the detour air guiding component more complete and connected, ensuring that the air flow can pass through or bypass these specific areas more smoothly, and realizing the basic function of the hair dryer.

[0045] As Figure 1 , Figure 2 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further defines that: a third flow channel 101 is formed between the other side of the bracket fixing sleeve 3 and the front shell assembly 1 and / or the rear cover assembly 2. By forming the third flow channel 101 between the other side of the bracket fixing sleeve 3 and the front shell assembly 1 and / or the rear cover assembly 2, the last pressurization function is achieved for the air flow, enabling the air flow to blow towards the user more efficiently and powerfully. At the same time, the internal space of the hair dryer is effectively utilized to implement the layout of the flow channel, making the overall structure more compact and complete, and enhancing the market competitiveness of the hair dryer.

[0046] As Figure 2 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the bracket fixing sleeve 3 includes an inner liner 31 and an outer cylinder sleeve 32. The inner liner 31 is arranged on the outer cylinder sleeve 32 and is located inside the outer cylinder sleeve 32. One end of the inner liner 31 is arc-shaped, and a first arc-shaped channel 301 is provided at the arc-shaped end. The outer cylinder sleeve 32 and the rear cover assembly 2 form a second flow channel 302, and the outer cylinder sleeve 32 and the inner side wall of the front shell assembly 1 form a third flow channel 101. By arranging the inner liner 31 inside the outer cylinder sleeve 32, a more effective detour air guiding assembly can be formed, which helps to guide the gas to flow more smoothly, improve the wind speed and air volume, and achieve a more efficient blowing effect. At the same time, arranging the inner liner 31 inside the outer cylinder sleeve 32 can make the inner liner 31 more stable, reducing the possibility of damage to the inner liner 31 caused by vibration or shaking during the operation of the hair dryer. Since one end of the inner liner 31 is arranged in an arc shape, the first arc-shaped channel 301 can be better formed, thereby reducing the resistance in the channel, increasing the wind speed and air volume, reducing losses. In addition, the arc-shaped structure is relatively stable, capable of withstanding a certain internal pressure and external impact, increasing the overall stability of the inner liner. At the same time, the arc-shaped channel is not easy to accumulate dust, facilitating cleaning and maintenance, and ensuring the unobstructedness of the detour air guiding assembly. Since the outer cylinder sleeve 32 and the rear cover assembly 2 form a second flow channel 302, and the structure of the second flow channel 302 is relatively narrow, the wind speed can be increased, the diffusion of the air flow in the channel and the loss of energy can be reduced, improving the utilization rate of energy. At the same time, it also helps to make the passing air flow more stable and concentrated, reducing the disorder and fluctuation of the air flow. In combination with the third flow channel 101 formed by the outer cylinder sleeve 32 and the front shell assembly 1, the wind pressure is further enhanced, the wind speed and wind force are further increased, and the working stability of the hair dryer is improved, meeting the user's needs for hairstyle design and enhancing the user experience.
