[0002] In the prior art, hair dryers are common electrical appliances in daily life, widely used in homes, barbershops, beauty salons, and other places, providing people with a convenient way to dry hair and surfaces. With increasing demands for hair dryer performance, people not only require hair dryers with heating functions, but also require other additional functions such as negative ion hair care. However, these functions often take up extra space, and excessive accessories in a hair dryer can easily cause airflow disturbances in the air duct, resulting in uneven airflow distribution and the formation of localized strong or weak wind areas, affecting the user experience.

[0005] The present application discloses a hair dryer comprising a housing assembly, an air distributor, and a blower assembly. The air distributor forms two independent airflow channels within the hair dryer—a first airflow channel and a second airflow channel. Air drawn in through the air inlet can flow to the first air outlet through the first and second airflow channels, respectively. This means that air drawn in through the air inlet can flow to the first air outlet through both channels, thereby reducing turbulence within the airflow channels. Furthermore, since the airflow within the hair dryer is improved, noise levels are also reduced. Furthermore, the design of the air distributor provides more space within the hair dryer, facilitating the integration of various accessories with additional functions. For example, a negative ion generator can be installed within the air distributor to deliver negative ions to the air outlet through the first or second airflow channels, achieving hair care. Alternatively, a heating assembly and temperature sensor can be installed to achieve constant temperature control, further enhancing the performance of the hair dryer. The air guide assembly reduces noise through its honeycomb structure as air flows through it, preventing excessive noise from the passing wind.

[0006] In one embodiment, the first airflow channel is formed between the outer side of the air distributor and the inner surface of the air outlet assembly, the air outlet assembly is provided with the first air outlet and an opening, the opening is respectively connected to the first airflow channel and the second airflow channel, the fan assembly is located in the air inlet channel, and the air inlet is connected to the opening. By connecting the handle assembly to the air outlet assembly, the handle assembly can provide a gripping portion for the user. Particularly, the handle assembly is provided with an air inlet and an air inlet channel, and a fan assembly is provided in the air inlet channel. During operation, the fan assembly can allow external air to enter the interior of the hair dryer from the air inlet, and flow through the opening to the first airflow channel and the second airflow channel in the air outlet assembly. Furthermore, a first airflow channel is formed between the outer side of the air distributor and the air outlet assembly, and a second airflow channel is formed on the inner side of the air distributor, and the first airflow channel and the second airflow channel then flow out to the first air outlet. The first and second airflow channels are arranged inside and outside, improving space utilization within the air outlet assembly and allowing for a more rational arrangement of the internal structure of the air outlet assembly. For example, a heating element can be placed in the first airflow channel, and a negative ion generator in the second airflow channel, facilitating various additional functions. Furthermore, the optimized design of the airflow channels allows for smoother air flow, thereby reducing noise levels.

[0007] In one embodiment, the air distributor comprises a connected shaft end and a radially extending plate, wherein the outer surface of the shaft end and the inner surface of the air outlet assembly form a first airflow channel, and the inner surface of the shaft end forms a second airflow channel. One radial end of the radially extending plate is connected to the outer surface of the shaft end, and the other radial end of the radially extending plate extends away from the outer surface. The radially extending plate is at least partially located at the opening so that airflow flows along one side of the radially extending plate to the first airflow channel and along the other side of the radially extending plate to the second airflow channel. By arranging the shaft end so that the axial direction of the shaft end is arranged along the axial direction of the air outlet assembly, the shaft end can divide the air outlet assembly into two channels, wherein the first airflow channel is formed between the outer surface of the shaft end and the inner surface of the air outlet assembly, and the second airflow channel is formed by the inner surface of the shaft end. Furthermore, the radially extending plate at least partially extends to the opening so that when air passes through the opening, it flows along one side of the radially extending plate to the first airflow channel and along the other side of the radially extending plate to the second airflow channel, thereby facilitating smooth airflow and avoiding airflow chaos and turbulence. Moreover, the airflow can be distributed into two channels, and the airflow in each channel can be better controlled and utilized, so that the hair dryer can provide more stable and concentrated wind force when blowing, thereby enhancing the blowing effect.

[0008] In one embodiment, the air distribution member further includes a guide plate, which is provided at the connection between the shaft end and the radial extension plate. The guide plate is at least partially located within the first airflow channel, and the guide plate is used to guide the airflow within the first airflow channel to flow toward the first air outlet. By providing a guide plate at the connection between the shaft end and the radial extension plate, the guide plate is located within the first airflow channel. When the airflow enters the first airflow channel, the guide plate reduces the dispersion and loss of the airflow, reduces the occurrence of turbulence within the first airflow channel, and enables the airflow to flow toward the first air outlet more efficiently. Furthermore, the hair dryer can provide a stable and concentrated blowing effect while reducing energy consumption and noise.

[0009] In one embodiment, the deflector is located on the side of the shaft end away from the opening. The deflector has an axially extending surface, which is used to guide the airflow in the first airflow channel axially toward the first air outlet. By positioning the deflector on the side of the shaft end away from the opening, airflow from the opening enters the first airflow channel in a vertically upward direction, passes through the shaft end, and then flows toward the side where the deflector is located. The deflector has an axially extending surface, which allows the airflow to flow along the axial direction of the surface. This allows the airflow in the first airflow channel to flow more directly and efficiently axially toward the first air outlet, thereby improving the efficiency and effectiveness of the hair dryer. Due to the more effective guidance and concentration of the airflow, the hair dryer requires less energy to achieve the same blowing effect. Furthermore, due to the reduced turbulence of the airflow in the channel, the noise level is also reduced. This helps to improve the energy efficiency and environmental performance of the hair dryer.

[0010] In one embodiment, the guide plate has a radial first end and a radial second end. The radial first end of the guide plate is disposed at the connection between the shaft end and the radially extending plate, and the radial second end of the guide plate abuts against the inner surface of the air outlet assembly. By configuring the guide plate to have a radial first end and a radial second end, when the airflow at the opening enters the first airflow channel in a vertically upward direction, the radially disposed plate body of the guide plate can guide the airflow during its ascent. This is conducive to enhancing the stability of the airflow guidance. The stable airflow guidance improves the blowing efficiency and reduces airflow waste and energy loss.

[0011] In one embodiment, the other radial end of the radial extension plate abuts against the inner surface of the air outlet assembly, and the radial extension plate can separate the air outlet assembly into a first accommodating space and a second accommodating space along the axial direction, the first air outlet is arranged close to the first accommodating space, the shaft end is located in the first accommodating space, and the second air flow channel connects the first air outlet and the second accommodating space. Specifically, the shaft end is cylindrical as a whole, and a radial extension plate is provided on one axial end of the shaft end, and the air outlet assembly is separated into a first accommodating space and a second accommodating space along the axial direction by the radial extension plate, the first accommodating space is arranged close to the first air outlet, and the second air flow channel formed on the inner surface of the shaft end connects the first air outlet and the second accommodating space, so that the airflow formed in the first accommodating space and the second accommodating space can flow out through the first air outlet, thereby achieving smooth flow and distribution of the airflow. Moreover, under the action of the radial extension plate, different accessories can be respectively provided in the first accommodating space and the second accommodating space of the air outlet assembly to realize different functions.

[0012] Furthermore, a first air flow channel is formed in the first accommodating space, and a second air flow channel is formed in the second accommodating space, wherein a through hole is formed on the inner surface of the shaft end, and the through hole connects the first accommodating space and the second accommodating space, so that the airflow in the first accommodating space and the second accommodating space can flow out to the first air outlet.

[0013] In one embodiment, the device further includes a circuit board assembly, which is disposed on the air outlet assembly and is at least partially located within the second storage space. By locating the circuit board assembly within the second storage space, the circuit board assembly can more effectively utilize the airflow flowing into the second airflow channel to dissipate heat, which helps reduce the operating temperature of the circuit board assembly and improve its stability and reliability. Furthermore, this allows for more efficient utilization of the space within the hair dryer, not only reducing the overall size of the hair dryer and making it more compact, but also providing ample space for other key components.

[0014] In some specific embodiments, a negative ion component can be provided in the second air flow channel and the second accommodating space. In this way, the negative ion component can be directly electrically connected to the circuit board component located in the second accommodating space, which is conducive to improving the compactness of the space, effectively utilizing the installation space in the hair dryer, and also improving the reliability of the electrical connection.

[0015] In one embodiment, the radially extending plate is provided with a wire hole extending through the plate surface, connecting the first and second storage spaces. By passing wires through the wire hole in the radially extending plate, the design of the wire hole allows wires to pass between the circuit board assembly and other electrical components located in the first storage space, helping to reduce the clutter and entanglement of wires within the hair dryer and making the wiring layout more rational and compact. Furthermore, pre-setting the wire hole in the radially extending plate simplifies the assembly process of the hair dryer, eliminating the need for assemblers to perform additional drilling or other complex operations during assembly, thereby improving assembly efficiency and product quality.

[0016] In one embodiment, the air outlet assembly includes an air duct shell and an air outlet nozzle, the air outlet nozzle is arranged on one axial end of the air duct shell, the air outlet nozzle is provided with the first air outlet, the air duct shell is provided with the opening, and the second air outlet and the third air outlet connected to the opening, the second air outlet and the third air outlet are both located on one end of the air duct shell near the air outlet nozzle, the second air outlet is connected to the first air flow channel, and the third air outlet is connected to the second air flow channel, so that the airflow of the first air flow channel and the second air flow channel both flow out through the first air outlet. By arranging the second air outlet connected to the first air flow channel and the third air outlet connected to the second air flow channel on the air duct shell, and arranging the air outlet nozzle on the end near the air duct shell where the second air outlet and the third air outlet are arranged, the air outlet nozzle is the final outlet position of the air flow, and the arrangement of the air outlet nozzle can concentrate and direct the air flow, thereby providing a better blowing effect. Furthermore, since the airflow from both the first and second airflow channels flows out through the first air outlet, the user can experience the effect of the mixed airflow from different airflow channels during use. Specifically, a heating component can be provided in one of the first and second airflow channels, and a negative ion component can be provided in the other of the first and second airflow channels. This allows the hair dryer to achieve both heating and negative ion air output functions, and the air is mixed and blown out together through the air outlet, thereby increasing the diversity and flexibility of the hair dryer and meeting the different blowing needs of users.

[0017] In one embodiment, a heating component is further included, and the heating component is arranged on the housing component or the air dividing component, and the heating component is at least partially located in the first air flow channel. By setting the heating component, the heating component can directly heat the air passing through the first air flow channel, so that the air flow out of the hair dryer has a certain temperature, so that the hair dryer can output hot air in addition to providing a blowing function. Furthermore, since the first air flow channel and the second air flow channel are arranged inside and outside through the air dividing component, the first air flow channel is located on the outside of the second air flow channel. During the operation of the heating component, the air flowing through the first air flow channel can also be heated under the action of heat conduction.

[0018] In one embodiment, a negative ion assembly is further included, disposed on the housing assembly or the air distributor, and at least partially located within the second airflow channel. The negative ion assembly within the second airflow channel generates negative ions. These negative ions, when in contact with the hair during hair drying, neutralize static electricity on the hair, reducing frizz and static electricity, thereby making the hair smoother and easier to comb. Furthermore, negative ions help moisturize and nourish the hair, improving its gloss and elasticity.

[0019] The positions of the heating component and the negative ion component can also be interchanged. For example, the heating component is located in the second air flow, and the negative ion component is located in the first air flow. The above-mentioned structure improves the internal structure of the hair dryer to provide a limited installation space for the heating component and the negative ion component, so that the air flow flows along a preset path in the hair dryer, which not only improves the air outlet effect, but also makes the internal structure of the hair dryer more compact.

[0039] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0041] The hair dryers according to some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0042] Please refer to the attached Figure 1 To the attached Figure 11, this embodiment discloses a hair dryer, including a shell component 1, the shell component 1 is provided with a accommodating cavity 101, and an air inlet 102 and a first air outlet 103 connected to the accommodating cavity 101; an air distribution piece 2, the air distribution piece 2 is arranged on the shell component 1, the air distribution piece 2 is located in the accommodating cavity 101, the outer side of the air distribution piece 2 and the air distribution piece 2 are enclosed to form a first air flow channel 201, the air inlet 102 and the first air flow channel 201 are connected to the first air outlet 103, and the inner side of the air distribution piece 2 forms a second air flow channel 202, the air inlet 102 and the second air flow channel 202 are connected to the first air outlet 103; a fan component 3, the fan component 3 is arranged on the shell component 1, the fan component 3 is located in the accommodating cavity 1 01, the shell assembly 1 includes a handle assembly 11 and an air outlet assembly 12, the air outlet assembly 12 is connected to the handle assembly 11, the air distributor 2 is arranged in the air outlet assembly 12, the handle assembly 11 is provided with an air inlet 102 and an air inlet channel 104, an air guide assembly 7, the air guide assembly 7 is arranged on the handle assembly, the air guide assembly 7 is located in the air inlet channel 104 and is arranged close to one end of the air inlet 102; the air guide assembly 7 is a honeycomb structure, the honeycomb structure has a plurality of ventilation holes 701, the ventilation holes 701 connect the air inlet 102 and the air inlet channel 104; the surface of the air guide assembly 7 facing the air inlet 102 is configured as an arc surface 702.

[0043] In a first aspect, the present application discloses a hair dryer comprising a housing assembly 1, an air distributor 2, and a blower assembly 3. The air distributor 2 forms two independent airflow channels within the hair dryer—a first airflow channel 201 and a second airflow channel 202. Air drawn into the air inlet 102 can flow to the first air outlet 103 through the first airflow channel 201 and the second airflow channel 202, respectively. This means that air drawn into the air inlet 102 can flow to the first air outlet 103 through both channels, thereby reducing turbulence within the airflow channels. Furthermore, since the airflow within the hair dryer is improved, noise levels are also reduced. Furthermore, the design of the air distributor 2 provides more space within the hair dryer, facilitating the integration of various accessories with additional functions. For example, a negative ion generator can be installed within the air distributor 2 to deliver negative ions to the air outlet through the first airflow channel 201 or the second airflow channel 202, thereby providing hair care. Alternatively, a heating assembly 5 and a temperature sensor can be installed to provide constant temperature control, further enhancing the performance of the hair dryer. The provision of the air guide assembly can reduce noise through the honeycomb structure when wind flows through, thereby preventing the passing wind from causing excessive noise.

[0044] like Figure 2 、 Figure 3 as well as Figure 7As shown, in addition to the features of the above-mentioned embodiment, this embodiment is further defined as follows: a first air flow channel 201 is formed between the outer side of the air dividing member 2 and the inner surface of the air outlet assembly 12, the air outlet assembly 12 is provided with a first air outlet 103 and an opening 105, the opening 105 is respectively connected to the first air flow channel 201 and the second air flow channel 202, the handle assembly 11 is provided with an air inlet 102 and an air inlet channel 104, the fan assembly 3 is located in the air inlet channel 104, and the air inlet 102 is connected to the opening 105. By connecting the handle assembly 11 with the air outlet assembly 12, the handle assembly 11 can provide a gripping portion for the user. Among them, the fan assembly 3 is provided in the air inlet channel 104, and the fan assembly 3 can allow external air to enter the interior of the hair dryer from the air inlet 102 during operation, and flow through the opening 105 to the first air flow channel 201 and the second air flow channel 202 in the air outlet assembly 12 for communication. Further, as Figure 5 and Figure 6 As shown, a first airflow channel 201 is formed between the outer side of the air distribution member 2 and the air outlet assembly 12, and a second airflow channel 202 is formed on the inner side of the air distribution member 2. The first airflow channel 201 and the second airflow channel 202 then flow out to the first air outlet 103. The first airflow channel 201 and the second airflow channel 202 are arranged inside and outside, thereby improving the space utilization within the air outlet assembly 12 and making it possible to arrange the internal structure of the air assembly reasonably. For example, a heating assembly 5 can be provided in the first airflow channel 201, and a negative ion generator can be provided in the second airflow channel 202, providing convenience for various additional functions. Furthermore, due to the optimized design of the airflow channel, the air flows more smoothly, thereby reducing the noise level.

[0045] like Figure 5 、 Figures 7 to 9As shown, in addition to the features of the above embodiment, this embodiment further defines that: the air distributor 2 includes a connected shaft end 21 and a radially extending plate 22. A first airflow channel 201 is formed between the outer surface of the shaft end 21 and the inner surface of the air outlet assembly 12, and a second airflow channel 202 is formed on the inner surface of the shaft end 21. One radial end of the radially extending plate 22 is connected to the outer surface of the shaft end 21, and the other radial end of the radially extending plate 22 extends away from the outer surface. The radially extending plate 22 is at least partially located at the opening 105, so that airflow flows along one side of the radially extending plate 22 to the first airflow channel 201 and along the other side of the radially extending plate 22 to the second airflow channel 202. By providing the shaft end 21, the axial direction of the shaft end 21 is arranged along the axial direction of the air outlet assembly 12, and the shaft end 21 can divide the air outlet assembly 12 into two channels: the first airflow channel 201 formed between the outer surface of the shaft end 21 and the inner surface of the air outlet assembly 12, and the second airflow channel 202 formed on the inner surface of the shaft end 21. Furthermore, radially extending plate 22 at least partially extends to opening 105, so that when air passes through opening 105, it flows along one side of radially extending plate 22 toward first airflow channel 201 and along the other side toward second airflow channel 202. This facilitates smooth airflow and avoids confusion and turbulence. Furthermore, the airflow is distributed into two channels, allowing the airflow in each channel to be better controlled and utilized, allowing the hair dryer to provide more stable and concentrated wind force, thereby enhancing the blowing effect.

[0046] like Figure 8 and Figure 9 As shown, in addition to the features of the above-described embodiment, this embodiment further provides that: the air divider 2 also includes a deflector 23, which is disposed at the junction of the shaft end 21 and the radially extending plate 22. The deflector 23 is at least partially located within the first airflow channel 201 and is configured to guide the airflow within the first airflow channel 201 toward the first air outlet 103. By disposing the deflector 23 at the junction of the shaft end 21 and the radially extending plate 22 and within the first airflow channel 201, airflow entering the first airflow channel 201 is guided by the deflector 23, reducing airflow dispersion and loss, and reducing turbulence within the first airflow channel 201, thereby enabling airflow to flow more efficiently toward the first air outlet 103. Furthermore, the hair dryer can provide a stable, concentrated blowing effect while also reducing energy consumption and noise.

[0047] It should be noted that Figure 7 The air distribution member 2 shown in FIG includes an axial end portion 21 and a radially extending plate 22. Figure 8The air distribution member 2 shown in FIG. 1 includes a shaft end portion 21 and a radially extending plate 22 , and a guide plate 23 provided at the connection between the shaft end portion 21 and the radially extending plate 22 .

[0048] like Figure 5 and Figure 9 As shown, in addition to the features of the above-described embodiment, this embodiment further provides that: a deflector 23 is located on the side of the shaft end 21 away from the opening 105. The deflector 23 has an axially extending surface that guides the airflow within the first airflow channel 201 axially toward the first air outlet 103. By positioning the deflector 23 on the side of the shaft end 21 away from the opening 105, airflow from the opening 105 enters the first airflow channel 201 in a vertically upward direction, passes through the shaft end 21, and then flows toward the side where the deflector 23 is located. The axially extending surface of the deflector 23 directs airflow along the axial direction of the surface, allowing airflow within the first airflow channel 201 to flow more directly and efficiently axially toward the first air outlet 103, thereby improving blowing efficiency and effectiveness. Due to the more effective guidance and concentration of airflow, the hair dryer requires less energy to achieve the same blowing effect. Furthermore, due to the reduced turbulence in the airflow channel, noise levels are also reduced. This helps improve the energy efficiency and environmental performance of the hair dryer.

[0049] like Figure 5 and Figure 9 As shown, in addition to the features of the above-described embodiment, this embodiment further defines: the deflector 23 has a radial first end 231 and a radial second end 232. The radial first end 231 of the deflector 23 is disposed at the connection between the shaft end 21 and the radially extending plate 22, and the radial second end 232 of the deflector 23 abuts against the inner surface of the air outlet assembly 12. By configuring the deflector 23 with the radial first end 231 and the radial second end 232, when the airflow from the opening 105 enters the first airflow channel 201 in a vertically upward direction, the radially disposed plate body of the deflector 23 can guide the airflow during its upward movement. This helps enhance the stability of the airflow guidance. Stable airflow guidance improves blowing efficiency and reduces airflow waste and energy loss.

[0050] like Figure 2 and Figure 5As shown, in addition to the features of the above-mentioned embodiment, this embodiment is further defined as follows: the other radial end of the radial extension plate 22 abuts against the inner surface of the air outlet component 12, and the radial extension plate 22 can separate the air outlet component 12 into a first accommodating space and a second accommodating space 203 along the axial direction, the first air outlet 103 is arranged close to the first accommodating space, the shaft end 21 is located in the first accommodating space, and the inner surface of the shaft end 21 forms a second air flow channel (202) connecting the first air inlet 103 and the second accommodating space 203. Specifically, the shaft end portion 21 is generally cylindrical in shape, and a radially extending plate 22 is disposed on one axial end of the shaft end portion 21. The radially extending plate 22 divides the air outlet assembly 12 into a first accommodating space and a second accommodating space 203 along the axial direction. The first accommodating space is located near the first air outlet 103, while a second airflow channel 202 formed on the inner surface of the shaft end portion 21 connects the first air inlet 103 and the second accommodating space 203. This allows airflow formed within the first accommodating space and the second accommodating space 203 to flow out through the first air outlet 103, thereby achieving smooth flow and distribution of airflow. Furthermore, the radially extending plate 22 allows different accessories to be placed in the first accommodating space and the second accommodating space 203 of the air outlet assembly 12 to achieve different functions.

[0051] Furthermore, a first air flow channel 201 is formed in the first accommodating space, and a second air flow channel 202 is formed in the second accommodating space 203, wherein the inner surface of the shaft end 21 forms the second air flow channel 202, and the second air flow channel 202 connects the first accommodating space and the second accommodating space 203, so that the airflow in the first accommodating space and the second accommodating space 203 can flow out to the first air outlet 103.

[0052] like Figure 2 As shown, in addition to the features of the above-described embodiment, this embodiment further defines: it also includes a circuit board assembly 4, which is disposed on the air outlet assembly 12, and at least partially located within the second accommodating space 203. By arranging the circuit board assembly 4 within the second accommodating space 203, on the one hand, the circuit board assembly 4 can more effectively utilize the airflow flowing into the second airflow channel 202 to dissipate heat, which helps to reduce the operating temperature of the circuit board assembly 4 and improve its stability and reliability. On the other hand, it can make more rational use of the space inside the hair dryer, not only helping to reduce the overall volume of the hair dryer, making it more compact, but also providing sufficient space for other key components.

[0053] In some specific embodiments, a negative ion component 6 can be provided in the second air flow channel 202 and the second accommodating space 203. In this way, the negative ion component 6 can be directly electrically connected to the circuit board component 4 located in the second accommodating space 203, which is conducive to improving the compactness of the space, effectively utilizing the installation space in the hair dryer, and also improving the reliability of the electrical connection.

[0054] like Figure 9 As shown, in addition to the features of the above-described embodiment, this embodiment further provides that: the radially extending plate 22 is provided with a wire hole 205 extending through the surface of the radially extending plate 22, and the wire hole 205 connects the first and second accommodating spaces 203. By passing the wires through the wire hole 205 in the radially extending plate 22, the design of the wire hole 205 allows the wires to pass between the circuit board assembly 4 and other electrical components located in the first accommodating space, helping to reduce the clutter and entanglement of the wires within the hair dryer and making the wiring layout more rational and compact. Furthermore, by pre-setting the wire hole 205 in the radially extending plate 22, the assembly process of the hair dryer can be simplified. Thus, the assembler does not need to perform additional drilling or other complex operations during the assembly process, thereby improving assembly efficiency and product quality.

[0055] like Figures 3 to 6As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the air outlet assembly 12 includes an air duct shell 121 and an air outlet nozzle 122, the air outlet nozzle 122 is arranged on one axial end of the air duct shell 121, the air outlet nozzle 122 is provided with a first air outlet 103, the air duct shell 121 is provided with an opening 105, and a second air outlet 106 and a third air outlet 107 connected to the opening 105, the second air outlet 106 and the third air outlet 107 are both located on one end of the air duct shell 121 close to the air outlet nozzle 122, the second air outlet 106 is connected to the first air flow channel 201, and the third air outlet 107 is connected to the second air flow channel 202, so that the airflow of the first air flow channel 201 and the second air flow channel 202 both flow out through the first air outlet 103. By providing a second air outlet 106 connected to the first airflow channel 201 and a third air outlet 107 connected to the second airflow channel 202 on the air duct housing 121, and disposing an air outlet nozzle 122 at one end of the air duct housing 121 near the second air outlet 106 and the third air outlet 107, the air outlet nozzle 122 serves as the final outlet of the airflow. The provision of the air outlet nozzle 122 can concentrate and direct the airflow, thereby providing a better blowing effect. Furthermore, since the airflow from the first airflow channel 201 and the second airflow channel 202 both flows out through the first air outlet 103, the user can experience the effect of the mixed airflow from different airflow channels during use. Specifically, a heating component 5 can be provided in one of the first air flow channel 201 and the second air flow channel 202, and a negative ion component 6 can be provided in the other of the first air flow channel 201 and the second air flow channel 202, so that the hair dryer can achieve the functions of heating and negative ion air output, and the negative ion air is mixed and blown out together after passing through the air outlet nozzle 122, thereby increasing the diversity and flexibility of the hair dryer and meeting the different blowing needs of users.

[0056] like Figure 8 As shown, in addition to the features of the above-mentioned embodiment, this embodiment is further defined as follows: it also includes a heating component 5, the heating component 5 is arranged on the outer shell component 1 or the air distribution component 2, and the heating component 5 is at least partially located in the first air flow channel 201. By setting the heating component 5, the heating component 5 can directly heat the air passing through the first air flow channel 201, so that the air flow out of the hair dryer has a certain temperature, so that the hair dryer can output hot air in addition to providing a blowing function. Furthermore, since the first air flow channel 201 and the second air flow channel 202 are arranged inside and outside through the air distribution component 2, the first air flow channel 201 is located on the outside of the second air flow channel 202. During the operation of the heating component 5, the air flowing through the first air flow channel 201 can also be heated under the action of heat conduction.

[0057] like Figure 2As shown, in addition to the features of the above-described embodiment, this embodiment further comprises: a negative ion assembly 6 disposed on the housing assembly 1 or the air distributor 2, and at least partially located within the second airflow channel 202. The negative ion assembly 6 disposed within the second airflow channel generates negative ions. These negative ions, when in contact with the hair during hair drying, neutralize static electricity on the hair, reducing frizz and static electricity, thereby making the hair smoother and easier to comb. Furthermore, the negative ions help moisturize and nourish the hair, improving its gloss and elasticity.

[0058] In other embodiments, the positions of the heating component 5 and the negative ion component 6 can also be interchanged. For example, the heating component 5 is located in the second air flow, and the negative ion component 6 is located in the first air flow. The above-mentioned structure improves the internal structure of the hair dryer to provide a limited installation space for the heating component 5 and the negative ion component 6, so that the air flow flows along a preset path in the hair dryer, which not only improves the air outlet effect, but also makes the internal structure of the hair dryer more compact.

[0059] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
