Hair dryer

Abstract

The application relates to a hair dryer, which comprises a wind tube shell and a light-emitting piece. The wind tube shell is provided with a containing cavity, and the circumferential side wall of the wind tube shell is provided with a light-transmitting part. The light-emitting piece is arranged in the containing cavity or the wind tube shell, and the light-emitting piece is arranged in correspondence with the light-transmitting part, and the light generated by the light-emitting piece can transmit through the light-transmitting part and be exposed to the circumferential side wall of the wind tube shell. When a user uses the hair dryer, since the circumferential side wall of the wind tube shell is always within the visual range of the user, the light-transmitting part and the light-emitting piece are arranged in correspondence with the circumferential side wall of the wind tube shell, the light generated by the light-emitting piece can be exposed to the circumferential side wall of the wind tube shell, so that the user can directly observe the color of the light while blowing hair, identify the current working mode of the hair dryer through the color of the light, and improve the user interaction experience. When the user stands in front of a mirror and holds the hair dryer, the user perceives soft ambient diffuse light instead of dazzling direct light, avoids the user from feeling uncomfortable, simultaneously creates a warm light and atmosphere, and makes the hair blowing experience of the user more comfortable.

Description

Technical Field

[0001] This application relates to the field of personal care product technology, and in particular to a hair dryer. Background Technology

[0002] Hair dryers are common personal care products used daily, primarily for drying hair. Since the heating element is located inside the nozzle, a PCB board is typically installed on the hair dryer to help users determine its current operating status. The light emitted from this PCB board changes color to indicate the current operating mode. However, the PCB board is usually located on the rear cover of the hair dryer, making it difficult for users to see the light color, resulting in a poor user experience. Furthermore, when users try to observe the light color, direct sunlight can cause glare in their eyes, further impacting the user experience. Utility Model Content

[0003] Therefore, it is necessary to provide a hair dryer in which users can identify the current working mode of the hair dryer by the color of the light emitted by the light-emitting component, thereby improving the user's interactive experience and avoiding glare caused by direct eye contact with the light, thus enhancing the user experience.

[0004] A hair dryer, comprising:

[0005] A ventilation duct shell, wherein the ventilation duct shell has a receiving cavity, and the peripheral sidewall of the ventilation duct shell has a light-transmitting portion; and

[0006] A light-emitting element is disposed in the accommodating cavity or the air duct shell. The light-emitting element is disposed corresponding to the light-transmitting part. The light emitted by the light-emitting element can pass through the light-transmitting part and be exposed on the peripheral wall of the air duct shell.

[0007] In the aforementioned hair dryer, since the peripheral wall of the nozzle shell is always within the user's line of sight when using it, the light-transmitting part and the light-emitting element are positioned corresponding to the peripheral wall of the nozzle shell. The light emitted by the light-emitting element can be seen on the peripheral wall of the nozzle shell, allowing the user to directly observe the color of the light while drying their hair and identify the current working mode of the hair dryer by the color of the light, thereby enhancing the user's interactive experience. When using a hair dryer, the user typically stands in front of a mirror and holds the hair dryer, raising it to the side, behind, or in front of their head. In this hair drying scenario, the user's main line of sight intersects with the axis of the nozzle shell. At the same time, the light emitted by the light-emitting element shines perpendicularly from the peripheral wall of the nozzle shell, and the propagation path of the light forms an angle with the user's line of sight. Thus, the user perceives soft, diffused ambient light rather than glaring direct light, which avoids user discomfort and improves the user experience. In addition, the light emitted from the nozzle shell can supplement the surrounding environment, creating warm light and a sense of atmosphere, making the user's hair drying experience more comfortable.

[0008] In one embodiment, the hair dryer further includes an air outlet and a bracket connected to the air outlet. Both the air outlet and the bracket are disposed within the receiving cavity and located on the air outlet side of the blower housing. The light-emitting element is mounted on at least one of the air outlet and the bracket. Thus, at least one of the air outlet and the bracket provides a mounting position for the light-emitting element, improving the convenience of installing the light-emitting element within the blower housing and the stability of the light-emitting element's installation.

[0009] In one embodiment, the air outlet component has a first mounting portion extending axially along the air duct shell; the bracket has a second mounting portion extending axially along the air duct shell, and the first mounting portion and the second mounting portion are connected; the light-emitting component is disposed on the first mounting portion and the second mounting portion. Thus, the first mounting portion and the second mounting portion are connected to form a circumferential side surface, which better supports the light-emitting component, improving the reliability of the light-emitting component's installation, making the light-emitting component more stable during use, and preventing the light-emitting component from falling off.

[0010] In one embodiment, the first mounting portion is a first mounting groove, and the second mounting portion is a second mounting groove. Both the first mounting groove and the second mounting groove extend axially along the duct shell, and the first mounting groove and the second mounting groove communicate with each other. At least a portion of the light-emitting element is disposed within the first mounting groove and the second mounting groove. Thus, the groove walls of the first and second mounting grooves can limit the position of the light-emitting element, improving the reliability of its installation. Simultaneously, by housing at least a portion of the light-emitting element within the first and second mounting grooves, the duct shell prevents the light-emitting element from being damaged by pressure, extending its service life and ensuring safe operation.

[0011] In one embodiment, at least one of the air outlet and the bracket is provided with a first positioning part, and the light-emitting element is provided with a second positioning part, with the first positioning part and the second positioning part engaging in a positioning fit. This improves the reliability of the light-emitting element's positioning.

[0012] In one embodiment, the peripheral sidewall of the duct shell is further provided with a light-transmitting hole, which communicates with the accommodating cavity and is disposed opposite to the light-emitting element. The light-transmitting part includes a first light-transmitting plate and a second light-transmitting plate. The first light-transmitting plate is disposed at the light-transmitting hole, and the second light-transmitting plate covers the first light-transmitting plate. In use, the light generated by the light-emitting element enters the first light-transmitting plate, which reflects and refracts the light, thereby homogenizing the concentrated and high-brightness light spot and making the light fully mixed within the first light-transmitting plate to form a light-emitting plane with a relatively uniform brightness distribution. Then, the light enters the second light-transmitting plate, which diffuses the light, blurring the brightness differences and making the duct shell present a smooth brightness transition effect.

[0013] In one embodiment, the peripheral sidewall of the blower housing is further provided with a recessed portion. The light-transmitting hole, the first light-transmitting plate, and the second light-transmitting plate are all located in the recessed portion. The outer surface of the second light-transmitting plate is located on the same circumference as the outer surface of the peripheral sidewall of the blower housing. By providing the recessed portion, the first and second light-transmitting plates are embedded in the recessed portion. The outer surface of the second light-transmitting plate and the outer surface of the peripheral sidewall of the blower housing form a continuous and smooth curved surface, achieving a seamless visual integration and smooth, stepless movement. When the user holds the blower housing or runs their fingers across it, it avoids a scratchy feeling and improves the grip experience of the hair dryer. Embedding the first and second light-transmitting plates in the recessed portion makes it less likely for dust to accumulate and facilitates cleaning and wiping the peripheral sidewall of the blower housing. In addition, the recessed portion provides a precise positioning reference for the installation of the first and second light-transmitting plates, simplifying the assembly process and helping to ensure assembly accuracy and stability. Furthermore, by placing the first and second light-transmitting plates on the peripheral sidewalls of the duct shell, they are positioned away from the heating wire. This prevents the first and second light-transmitting plates from warping or deforming due to internal stress generated by thermal expansion and contraction within the duct shell, thus ensuring the stability of the light output visible through the duct shell. Simultaneously, it also prevents the first and second light-transmitting plates from being disturbed by airflow, ensuring the stability of the light output visible through the duct shell.

[0014] In one embodiment, the blower housing is further provided with an air inlet and an air outlet, both of which are connected to the accommodating cavity; the blower also includes an air inlet screen, which is disposed at the air inlet, and the light-emitting element is disposed at one end of the blower housing near the air inlet screen. Thus, the cold air entering the blower housing through the air inlet screen can dissipate heat from the light-emitting element, reducing its temperature.

[0015] In one embodiment, the light-emitting element includes a first light-emitting part and a second light-emitting part. The first light-emitting part has a ring-shaped structure and is disposed on the peripheral sidewall of the blower housing. The second light-emitting part has a strip-shaped structure and extends from the first light-emitting part along the axial direction of the blower housing towards the air outlet. In use, both the first and second light-emitting parts can generate light. From the outside, the end of the blower housing with the air inlet forms a light ring, and the peripheral sidewall of the blower housing forms a light strip parallel to the axis. This dual light effect superimposed creates a unique visual identifier, thereby improving the recognizability of the hair dryer.

[0016] In one embodiment, the first light-emitting part is sleeved on the peripheral sidewall of the air inlet mesh and located between the peripheral sidewall of the air inlet mesh and the peripheral sidewall of the air duct shell. In this way, the peripheral sidewall of the air inlet mesh can provide support for the first light-emitting part, improving the reliability of its installation. Furthermore, by using the air inlet mesh to house the first light-emitting part, there is no need for additional components to support the light-emitting element, reducing the number of parts and thus lowering costs.

[0017] In one embodiment, the peripheral wall of the air inlet mesh is provided with a limiting protrusion, which abuts against the inner surface of the peripheral wall of the air duct shell. The limiting protrusion has a clearance opening through which the second light-emitting part passes. During assembly, the air duct shell is fitted over the air inlet mesh, with the inner surface of the peripheral wall of the air duct shell abutting against the limiting protrusion. The limiting protrusion can radially position the air duct shell, ensuring that the air duct shell and the air inlet mesh are coaxial and do not wobble. At the same time, it can also prevent the air duct shell from squeezing the light-emitting element and causing damage to the light-emitting element, thus extending the service life of the light-emitting element.

[0018] In one embodiment, the hair dryer further includes an inner housing for housing the blower. The inner housing is disposed within the receiving cavity and located on the side of the air inlet mesh facing the air outlet. The inner housing is connected to the air inlet mesh. The inner housing has a mounting groove, and the second light-emitting part is disposed within the mounting groove. Thus, the groove wall of the mounting groove can limit the position of the second light-emitting part, improving the reliability of its installation. Simultaneously, housing the second light-emitting part within the mounting groove prevents the blower casing from compressing and damaging the second light-emitting part, extending its service life.

[0019] In one embodiment, at least one of the air inlet mesh and the inner housing is provided with a first positioning structure, and at least one of the first light-emitting part and the second light-emitting part is provided with a second positioning structure, wherein the first positioning structure and the second positioning structure are positioned and engaged. This ensures the reliability of the positioning of the light-emitting element.

[0020] In one embodiment, the light-transmitting portion includes a first light-transmitting element and a second light-transmitting element. The first light-transmitting element is disposed on the inner surface of the peripheral sidewall of the air duct shell and covers the first light-emitting portion; the second light-transmitting element is disposed on the outer surface of the peripheral sidewall of the air duct shell and covers the second light-emitting portion, with one end of the second light-transmitting element covering the first light-transmitting element. In use, the light generated by the first light-emitting portion passes through the first light-transmitting element to form a light ring at the end of the air duct shell with an air inlet. Simultaneously, the light generated by the second light-emitting portion passes through the second light-transmitting element to form a light strip on the peripheral sidewall of the air duct shell.

[0021] In one embodiment, the inner surface of the peripheral sidewall of the duct shell is provided with a first receiving groove, the first receiving groove extending circumferentially along the duct shell, and the first light-transmitting element is disposed in the first receiving groove; thus, by disposing the first light-transmitting element in the first receiving groove, the groove wall of the first receiving groove can limit the first light-transmitting element, improve the stability of the installation of the first light-transmitting element, and at the same time, the first light-transmitting element and the duct shell share a portion of the wall thickness, eliminating the additional radial assembly space required for independently installing the first light-transmitting element, thereby also reducing the radial dimension of the duct shell.

[0022] And / or, the outer surface of the peripheral sidewall of the blower housing is further provided with a second receiving groove, the second receiving groove extending along the axial direction of the blower housing, the second light-transmitting element being disposed within the second receiving groove, and the outer surface of the second light-transmitting element being located on the same circumference as the outer surface of the peripheral sidewall of the blower housing. By providing the second receiving groove, the second light-transmitting element is embedded within it, and the outer surface of the second light-transmitting element and the outer surface of the peripheral sidewall of the blower housing form a continuous and smooth curved surface, achieving a seamless visual integration and smooth, stepless movement. This avoids a scratchy feel when the user holds the blower housing or runs their fingers across it, improving the user experience. Embedding the second light-transmitting element within the second receiving groove also prevents dust accumulation, making it easier to clean and wipe the peripheral sidewall of the blower housing. Furthermore, the second receiving groove provides a precise positioning reference for the installation of the second light-transmitting element, simplifying the assembly process and helping to ensure assembly accuracy and stability.

[0023] In one embodiment, the light-transmitting portion further includes a third light-transmitting element, the third light-transmitting element being symmetrically positioned relative to the second light-transmitting element with respect to the blower housing, and one end of the third light-transmitting element covering the first light-transmitting element. In use, the light generated by the first light-emitting portion can pass through the first and second light-transmitting elements and be revealed on the side of the blower housing opposite to the handle housing. Simultaneously, the light generated by the first light-emitting portion can also pass through the first and third light-transmitting elements and be revealed on the side of the blower housing closest to the handle housing, thus avoiding a "yin-yang" effect where one side of the blower housing is brighter than the other. Furthermore, when the user uses the hair dryer, a complete and symmetrical light strip is visible, which helps improve the visibility of the hair dryer's indicator light.

[0024] In one embodiment, the outer surface of the peripheral sidewall of the blower housing is further provided with a third receiving groove. The third receiving groove is disposed opposite to the second light-transmitting element and extends along the axial direction of the blower housing. The third light-transmitting element is disposed within the third receiving groove, and the outer surface of the third light-transmitting element and the outer surface of the peripheral sidewall of the blower housing are located on the same circumference. By providing the third receiving groove, the third light-transmitting element is embedded in the third receiving groove, and the outer surface of the third light-transmitting element and the outer surface of the peripheral sidewall of the blower housing form a continuous and smooth curved surface, achieving a seamless visual integration and smooth, stepless movement. When the user holds the blower housing or runs their fingers across the blower housing, it avoids a scratchy feeling and improves the user experience of the hair dryer. Embedding the third light-transmitting element in the third receiving groove makes it less likely for dust to accumulate and makes it easier to clean and wipe the peripheral sidewall of the blower housing. In addition, the third receiving groove also provides a precise positioning reference for the installation of the third light-transmitting element, simplifying the assembly process and helping to ensure assembly accuracy and stability.

[0025] In one embodiment, the hair dryer further includes a handle housing connected to the blower housing, with at least a portion of the light-transmitting portion located on the side of the blower housing opposite to the handle housing. This prevents light exposed on the peripheral wall of the blower housing from being blocked, ensuring that light is always visible and improving the user experience. Furthermore, when a user stands in front of a mirror and holds the hair dryer to the side or in front of their head, regardless of how they hold the handle, they can still see the light exposed on the peripheral wall of the blower housing.

Detailed Implementation

[0043] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0044] See Figure 1 and Figure 4 The hair dryer provided in one embodiment of this application includes a hair dryer housing 10 and a light-emitting element 20.

[0045] See Figure 3 The duct shell 10 is provided with a receiving cavity 11, and the peripheral sidewall of the duct shell 10 is provided with a light-transmitting part 12. It should be noted that the peripheral sidewall of the duct shell 10 refers to the cylindrical surface surrounding the axial direction of the duct shell 10, and S is used to represent the axial direction of the duct shell 10.

[0046] See Figure 3 and Figure 4 The light-emitting element 20 is disposed within the receiving cavity 11; or, the light-emitting element 20 is disposed in the peripheral wall of the duct shell 10. The light-emitting element 20 is disposed corresponding to the light-transmitting part 12, and the light generated by the light-emitting element 20 can pass through the light-transmitting part 12 and be exposed on the peripheral wall of the duct shell 10.

[0047] When a user uses a hair dryer, since the peripheral wall of the hair dryer housing 10 is always within the user's line of sight, the light-transmitting part 12 and the light-emitting element 20 are positioned corresponding to the peripheral wall of the hair dryer housing 10. The light emitted by the light-emitting element 20 can be exposed on the peripheral wall of the hair dryer housing 10. In this way, the user can directly observe the color of the light while drying their hair and identify the current working mode of the hair dryer by the color of the light, thereby improving the user's interactive experience.

[0048] When using a hair dryer, users typically stand in front of a mirror and hold the hair dryer, positioning it to the side, behind, or in front of their head. In this scenario, the user's main line of sight intersects the axis of the hair dryer housing 10, while the light emitted from the light-emitting element 20 shines perpendicularly from the peripheral wall of the hair dryer housing 10, with the light's propagation path forming an angle with the user's line of sight. Thus, the user perceives soft, diffused ambient light, rather than glaring direct light, preventing discomfort and enhancing the user experience. Furthermore, the light emanating from the hair dryer housing 10 can supplement the surrounding environment, creating warm lighting and a sense of atmosphere, making the hair drying experience more pleasant.

[0049] In one embodiment, the light-emitting element 20 includes a PCB board and multiple LED beads, all of which are disposed on the PCB board. The LED beads can emit light of different colors corresponding to different air temperatures. The hair dryer has different speed settings, each corresponding to a different air temperature. The PCB board can control the LED beads to emit different colors of light according to different air temperatures. This allows the user to determine the current working mode of the hair dryer based on the color of the light, while also creating an ambient lighting effect and enhancing the user experience.

[0050] In one embodiment, see Figure 3 and Figure 10 The hair dryer also includes a handle housing 70. The handle housing 70 is connected to the nozzle housing 10, and at least a portion of the light-transmitting part 12 is located on the side of the nozzle housing 10 opposite to the handle housing 70. During use, the user typically holds the handle housing 70. Therefore, in this embodiment, at least a portion of the light-transmitting part 12 is located on the side of the nozzle housing 10 opposite to the handle housing 70. This prevents the light exposed on the peripheral wall of the nozzle housing 10 from being blocked, ensuring the light is always visible and improving the user experience. Furthermore, whether the user stands in front of a mirror and holds the hair dryer to the side or in front of their head, regardless of how the user holds the handle, the light exposed on the peripheral wall of the nozzle housing 10 can be seen.

[0051] In one embodiment, see Figure 2 and Figure 4 The hair dryer also includes an air outlet 30 and a bracket 40 connected to the air outlet 30. Both the air outlet 30 and the bracket 40 are located within the receiving cavity 11 and on the air outlet side of the hair dryer housing 10. The air outlet 30 has an air outlet 32 ​​that communicates with the receiving cavity 11. Thus, the airflow entering the receiving cavity 11 through the air inlet 14 can be blown out through the air outlet 32, forming a stable airflow for rapid hair drying. The heating element and circuit board are both mounted on the bracket 40, which provides a mounting position for the heating element and circuit board, improving the ease of installation.

[0052] Furthermore, the light-emitting element 20 is mounted on at least one of the air outlet element 30 and the bracket 40. Optionally, the light-emitting element 20 is mounted on the air outlet element 30; or, the light-emitting element 20 is mounted on the bracket 40; or, see [reference] Figure 4 The light-emitting element 20 is mounted on the air outlet 30 and the bracket 40. Thus, at least one of the air outlet 30 and the bracket 40 provides a mounting position for the light-emitting element 20, improving the convenience of installing the light-emitting element 20 inside the air duct housing 10 and the stability of the installation of the light-emitting element 20.

[0053] In one embodiment, see Figure 7 The air outlet component 30 is provided with a first mounting part 31, which extends along the axial direction of the air duct shell 10.

[0054] It should be noted that the extension of the first mounting portion 31 along the axial direction of the duct shell 10 means that the extension direction of the first mounting portion 31 is approximately the same as the axial direction of the duct shell 10. Optionally, the extension direction of the first mounting portion 31 is parallel to the axial direction of the duct shell 10; or, the extension direction of the first mounting portion 31 intersects the axial direction of the duct shell 10, that is, the extension direction of the first mounting portion 31 is inclined relative to the axial direction of the duct shell 10.

[0055] See Figure 8 The bracket 40 is provided with a second mounting part 41, which extends along the axial direction of the air duct shell 10.

[0056] It should be noted that the extension of the second mounting portion 41 along the axial direction of the duct shell 10 means that the extension direction of the second mounting portion 41 is approximately the same as the axial direction of the duct shell 10. Optionally, the extension direction of the second mounting portion 41 is parallel to the axial direction of the duct shell 10; or, the extension direction of the second mounting portion 41 intersects the axial direction of the duct shell 10, that is, the extension direction of the second mounting portion 41 is inclined relative to the axial direction of the duct shell 10.

[0057] See Figure 4 and Figure 5 The first mounting portion 31 and the second mounting portion 41 are connected, and the light-emitting element 20 is disposed on the first mounting portion 31 and the second mounting portion 41. In this way, the first mounting portion 31 and the second mounting portion 41 are connected to form a peripheral side surface, which can better support the light-emitting element 20, which helps to improve the reliability of the installation of the light-emitting element 20, making the light-emitting element 20 more stable during use and preventing the light-emitting element 20 from falling off.

[0058] In one embodiment, see Figure 4 , Figure 5 and Figure 6 The first mounting portion 31 is a first mounting groove 311, and the second mounting portion 41 is a second mounting groove 411. Both the first mounting groove 311 and the second mounting groove 411 extend axially along the duct shell 10 and are connected. At least a portion of the light-emitting element 20 is disposed within the first mounting groove 311 and the second mounting groove 411. Thus, the groove walls of the first mounting groove 311 and the second mounting groove 411 can limit the position of the light-emitting element 20, improving the reliability of its installation. Furthermore, by housing at least a portion of the light-emitting element 20 within the first mounting groove 311 and the second mounting groove 411, damage to the light-emitting element 20 caused by the duct shell 10 pressing against it can be prevented, thereby extending the service life of the light-emitting element 20 and improving its safety during use.

[0059] It should be noted that the statement that both the first mounting groove 311 and the second mounting groove 411 extend along the axial direction of the duct shell 10 means that the extension directions of the first mounting groove 311 and the second mounting groove 411 are approximately the same as the axial direction of the duct shell 10. Optionally, the extension directions of the first mounting groove 311 and the second mounting groove 411 are parallel to the axial direction of the duct shell 10; or, the extension directions of the first mounting groove 311 and the second mounting groove 411 intersect the axial direction of the duct shell 10, that is, the extension directions of the first mounting groove 311 and the second mounting groove 411 are inclined relative to the axial direction of the duct shell 10.

[0060] In one embodiment, see Figure 5 , Figure 6 and Figure 7 The first mounting portion 31 is provided with at least two first protruding ribs 313. Both first protruding ribs 313 extend axially along the duct shell 10 and are spaced apart circumferentially along the duct shell 10. Adjacent first protruding ribs 313 form a first mounting groove 311. The inner surface of the circumferential sidewall of the duct shell 10 abuts against the first protruding ribs 313. During assembly, the duct shell 10 is fitted over the air outlet component 30, with the inner surface of the circumferential sidewall of the duct shell 10 abutting against the first protruding ribs 313. The first protruding ribs 313 provide radial positioning for the duct shell 10, ensuring that the duct shell 10 and the air outlet component 30 are coaxial and do not wobble. They also prevent the duct shell 10 from squeezing the light-emitting component 20, thus extending the service life of the light-emitting component 20 and improving its safety during use.

[0061] Specifically, in this embodiment, see [reference] Figure 5 Four first protruding ribs 313 are provided, each extending axially along the duct shell 10 and spaced apart circumferentially along the duct shell 10. Two of the first protruding ribs 313 form a first mounting groove 311, and the other two first protruding ribs 313 also form a first mounting groove 311. Thus, the four first protruding ribs 313 form two first mounting grooves 311.

[0062] In one embodiment, see Figure 4 , Figure 5 and Figure 6The second mounting portion 41 is provided with at least two second protruding ribs 413. Both second protruding ribs 413 extend axially along the duct shell 10 and are spaced apart circumferentially along the duct shell 10. Adjacent second protruding ribs 413 form a second mounting groove 411. The inner surface of the circumferential sidewall of the duct shell 10 abuts against the second protruding ribs 413. During assembly, the duct shell 10 is fitted over the air outlet component 30, with the inner surface of the circumferential sidewall of the duct shell 10 abutting against the second protruding ribs 413. The second protruding ribs 413 provide radial positioning for the duct shell 10, ensuring that the duct shell 10 and the air outlet component 30 are coaxial and do not wobble. They also prevent the duct shell 10 from squeezing the light-emitting component 20, thus extending the service life of the light-emitting component 20 and improving its safety during use.

[0063] Specifically, in this embodiment, see [reference] Figure 5 Four second ribs 413 are provided, each extending axially along the duct shell 10 and spaced apart circumferentially along the duct shell 10. Two of the second ribs 413 form a first mounting groove 311, and the other two form a second mounting groove 411. Thus, the four second ribs 413 form two second mounting grooves 411, and the two first mounting grooves 311 and the two second mounting grooves 411 are connected in a one-to-one correspondence.

[0064] In one embodiment, at least one of the air outlet 30 and the bracket 40 is provided with a first positioning part 312, and the light-emitting part 20 is provided with a second positioning part 21. The first positioning part 312 and the second positioning part 21 are positioned and engaged. In this way, the reliability of the positioning of the light-emitting part 20 can be improved by the cooperation of the first positioning part 312 and the second positioning part 21.

[0065] Furthermore, one of the first positioning part 312 and the second positioning part 21 is a positioning hole, and the other of the first positioning part 312 and the second positioning part 21 is a positioning protrusion, which is disposed inside the positioning hole. During assembly, the positioning protrusion is disposed inside the positioning hole to realize the positioning of the light-emitting component 20, which simplifies the assembly process and improves assembly efficiency.

[0066] Specifically, in this embodiment, see [reference] Figure 4 The light-emitting component 20 is provided with multiple positioning holes, and the first mounting part 31 of the air outlet component 30 and the second mounting part 41 of the bracket 40 are both provided with multiple positioning protrusions. The multiple positioning protrusions are correspondingly located in the positioning holes, which improves the reliability of the positioning of the light-emitting component 20. At the same time, the positioning protrusions facilitate quick alignment and installation in the factory, improving assembly efficiency. If the light-emitting component 20 has a specific installation direction, positioning components of different specifications or styles can also be provided to facilitate accurate positioning and installation by factory workers.

[0067] In one embodiment, see Figure 2The peripheral wall of the air duct housing 10 is also provided with a light-transmitting hole 16. The light-transmitting hole 16 is located on the side of the air duct housing 10 away from the handle housing 70. The light-transmitting hole 16 communicates with the receiving cavity 11 and extends along the axial direction of the air duct housing 10 and is arranged opposite to the light-emitting element 20.

[0068] See Figure 3 The light-transmitting part 12 includes a first light-transmitting plate 121, which is disposed at the light-transmitting hole 16. Optionally, the first light-transmitting plate 121 is made of transparent or semi-transparent material. In use, the light generated by the light-emitting element 20 passes through the first light-transmitting plate 121, so that the light can be exposed on the peripheral wall of the duct shell 10.

[0069] See Figure 1 and Figure 3 The light-transmitting section 12 also includes a second light-transmitting plate 122, which covers the first light-transmitting plate 121. Optionally, the second light-transmitting plate 122 is made of transparent or semi-transparent material. In use, the light generated by the light-emitting element 20 enters the first light-transmitting plate 121. The first light-transmitting plate 121 reflects and refracts the light, thereby homogenizing the concentrated and high-brightness light spot and making the light fully mix within the first light-transmitting plate 121 to form a light-emitting plane with a relatively uniform brightness distribution. Then, the light enters the second light-transmitting plate 122, which diffuses the light, blurring the brightness differences and making the duct shell 10 exhibit a smooth brightness transition effect.

[0070] In one embodiment, see Figure 2 The outer surface of the peripheral wall of the blower housing 10 is also provided with a recess 15, which is located on the side of the blower housing 10 away from the handle housing 70 and recessed into the receiving cavity 11. The light-transmitting hole 16, the first light-transmitting plate 121, and the second light-transmitting plate 122 are all located in the recess 15. The outer surface of the second light-transmitting plate 122 is on the same circumference as the outer surface of the peripheral wall of the blower housing 10. By providing the recess 15, the first light-transmitting plate 121 and the second light-transmitting plate 122 are embedded in the recess 15, and the outer surface of the second light-transmitting plate 122 forms a continuous and smooth curved surface with the outer surface of the peripheral wall of the blower housing 10, achieving a seamless visual integration and smooth, stepless movement. When the user holds the blower housing 10 or runs their fingers over the blower housing 10, it avoids a scratchy feeling and improves the grip experience of the hair dryer. The first light-transmitting plate 121 and the second light-transmitting plate 122 are embedded in the recess 15, which makes it less likely for dust to accumulate and easier to clean and wipe the peripheral walls of the air duct shell 10. In addition, the recess 15 provides a precise positioning reference for the installation of the first light-transmitting plate 121 and the second light-transmitting plate 122, simplifies the assembly process, and helps to ensure assembly accuracy and stability.

[0071] Furthermore, by placing the first light-transmitting plate 121 and the second light-transmitting plate 122 on the peripheral sidewall of the air duct shell 10, the first light-transmitting plate 121 and the second light-transmitting plate 122 are kept away from the heating wire. This prevents the first light-transmitting plate 121 and the second light-transmitting plate 122 from warping or other deformations caused by internal stress generated by thermal expansion and contraction within the air duct shell 10, thus ensuring the stability of the light display. Simultaneously, it also prevents the first light-transmitting plate 121 and the second light-transmitting plate 122 from being disturbed by airflow, ensuring the stability of the light display. In another embodiment, see [reference needed]. Figure 9 The air duct shell 10 is also provided with an air inlet 14 and an air outlet 13, both of which are connected to the receiving cavity 11. The air inlet 14 and the air outlet 13 are respectively located at both ends of the axial direction of the air duct shell 10.

[0072] See Figure 11 and Figure 12 The hair dryer also includes an air inlet mesh 50, which is located at the air inlet 14, and a light-emitting element 20 is located at the end of the blower housing 10 near the air inlet mesh 50. In this way, the cold air entering the blower housing 10 through the air inlet mesh 50 can dissipate heat from the light-emitting element 20 and reduce its temperature.

[0073] In one embodiment, see Figure 15 The light-emitting component 20 includes a first light-emitting part 22 and a second light-emitting part 23. The first light-emitting part 22 has a ring structure and is disposed on the peripheral sidewall of the blower housing 10. The second light-emitting part 23 has a strip structure and is disposed on the side of the blower housing 10 away from the handle housing 70. The second light-emitting part 23 extends from the first light-emitting part 22 along the axial direction of the blower housing 10 towards the air outlet 13. In use, both the first light-emitting part 22 and the second light-emitting part 23 can generate light. From the outside, the end of the blower housing 10 with the air inlet 14 forms a light ring, and the peripheral sidewall of the blower housing 10 forms a light strip parallel to the axis. This dual light effect superimposed forms a unique visual identifier, thereby improving the recognizability of the hair dryer.

[0074] Further, see Figure 11 and Figure 12 The first light-emitting part 22 is fitted onto the peripheral sidewall of the air inlet mesh 50 and is located between the peripheral sidewall of the air inlet mesh 50 and the peripheral sidewall of the air duct shell 10. In this way, the peripheral sidewall of the air inlet mesh 50 can provide support for the first light-emitting part 22, improving the reliability of the installation of the first light-emitting part 22. At the same time, by using the air inlet mesh 50 to set the first light-emitting part 22, there is no need to set additional components to support the light-emitting element 20, reducing the number of parts and helping to reduce costs.

[0075] In one embodiment, see Figure 12 and Figure 15The air inlet mesh 50 has a limiting protrusion 51 on its peripheral sidewall. The limiting protrusion 51 extends along the peripheral sidewall of the air inlet mesh 50 to form a ring structure, and the limiting protrusion 51 abuts against the inner surface of the peripheral sidewall of the air duct shell 10. During assembly, the air duct shell 10 is fitted over the air inlet mesh 50, and the inner surface of the peripheral sidewall of the air duct shell 10 abuts against the limiting protrusion 51. The limiting protrusion 51 can radially position the air duct shell 10, ensuring that the air duct shell 10 and the air inlet mesh 50 are coaxial and do not wobble. At the same time, it can also prevent the air duct shell 10 from squeezing the light-emitting element 20 and causing damage to the light-emitting element 20, thus extending the service life of the light-emitting element 20.

[0076] Further, see Figure 15 The limiting protrusion 51 is provided with a clearance opening 511 through which the second light-emitting part 23 passes. By providing the clearance opening 511, the clearance opening 511 can avoid the second light-emitting part 23, allowing the second light-emitting part 23 to extend from the first light-emitting part 22 toward the air outlet 13, thereby avoiding interference between the second light-emitting part 23 and the air inlet mesh 50. At the same time, a guide gap is formed between the limiting protrusion 51 and the air inlet mesh 50, so that a local negative pressure backflow is generated on the leeward side of the clearance opening 511 when the blower is working. This can remove dust from the surface of the second light-emitting part 23, thereby preventing dust accumulation on the surface of the second light-emitting part 23.

[0077] In one embodiment, see Figure 12 and Figure 13 The hair dryer also includes an inner housing 60 for housing the blower. The inner housing 60 is disposed within the accommodating cavity 11 and located on the side of the air inlet 50 facing the air outlet 13, and the inner housing 60 is connected to the air inlet 50. The blower is provided inside the inner housing 60, and the blower is used to drive outside air into the accommodating cavity 11 through the air inlet 14 and blow it out through the air outlet 13.

[0078] Further, see Figure 12 and Figure 13 The inner housing 60 is provided with an assembly groove 61, and the second light-emitting part 23 is disposed in the assembly groove 61. In this way, the groove wall of the assembly groove 61 can limit the second light-emitting part 23, improve the reliability of the installation of the second light-emitting part 23, and at the same time, by accommodating the second light-emitting part 23 in the assembly groove 61, it can prevent the second light-emitting part 23 from being squeezed and damaged by the duct shell 10, thereby extending the service life of the light-emitting component 20.

[0079] In one embodiment, at least one of the air inlet mesh 50 and the inner housing 60 is provided with a first positioning structure 611, and at least one of the first light-emitting part 22 and the second light-emitting part 23 is provided with a second positioning structure 231. The first positioning structure 611 and the second positioning structure 231 are positioned and engaged. In this way, the reliability of the positioning of the light-emitting element 20 can be guaranteed by the cooperation of the first positioning structure 611 and the second positioning structure 231.

[0080] Furthermore, one of the first positioning structure 611 and the second positioning structure 231 is a positioning hole, and the other of the first positioning part 312 and the second positioning part 21 is a positioning protrusion, which is disposed within the positioning hole. During assembly, the positioning protrusion is disposed within the positioning hole to achieve positioning of the light-emitting component 20, thereby simplifying the assembly process and improving assembly efficiency.

[0081] Specifically, in this embodiment, see [reference]. Figure 13 The second light-emitting part 23 is provided with multiple positioning holes, and the inner housing 60 is provided with multiple positioning protrusions. The multiple positioning protrusions are arranged one-to-one in the multiple positioning holes, thereby improving the reliability of the positioning of the second light-emitting part 23.

[0082] In one embodiment, see Figure 10 , Figure 12 and Figure 14 The light-transmitting portion 12 includes a first light-transmitting element 123 and a second light-transmitting element 124. The first light-transmitting element 123 is disposed on the inner surface of the peripheral sidewall of the air duct housing 10 and covers the first light-emitting portion 22. The second light-transmitting element 124 is disposed on the outer surface of the side of the air duct housing 10 opposite to the handle housing 70 and covers the second light-emitting portion 23, with one end of the second light-transmitting element 124 covering the first light-transmitting element 123. In use, the light generated by the first light-emitting portion 22 passes through the first light-transmitting element 123 to form a light ring at the end of the air duct housing 10 with the air inlet 14. At the same time, the light generated by the second light-emitting portion 23 passes through the second light-transmitting portion 12 to form a light strip on the peripheral sidewall of the air duct housing 10.

[0083] Specifically, in this embodiment, see [reference] Figure 10 and Figure 11 The length of the second light-emitting part 23 is less than the axial length of the duct shell 10, and the length of the second light-transmitting element 124 is adapted to the axial length of the duct shell 10. Thus, the light generated by the second light-emitting part 23 can be conducted through total internal reflection and scattering, and finally emitted uniformly from the outer surface of the second light-transmitting element 124, thereby achieving a continuous and dark-area-free light emission effect in the area of ​​the duct shell 10 corresponding to the second light-transmitting element 124. Furthermore, using a shorter second light-emitting part 23 to excite the full-length light-guiding area reduces the number of LEDs required for the second light-emitting part 23 and the total power, thereby reducing the power consumption and heat of the light-emitting element 20.

[0084] In one embodiment, see Figure 11 and Figure 12The inner surface of the peripheral sidewall of the duct shell 10 is provided with a first receiving groove 17, which extends circumferentially along the duct shell 10. The first light-transmitting element 123 is disposed within the first receiving groove 17. By embedding the first light-transmitting element 123 within the first receiving groove 17, the groove wall of the first receiving groove 17 can limit the position of the first light-transmitting element 123, improving the stability of the installation of the first light-transmitting element 123. At the same time, the first light-transmitting element 123 shares a portion of the wall thickness with the duct shell 10, eliminating the additional radial assembly space required for independently installing the first light-transmitting element 123, thereby reducing the radial dimension of the duct shell 10.

[0085] See Figure 9 and Figure 10 The outer surface of the peripheral wall of the blower housing 10 is also provided with a second receiving groove 18, which extends along the axial direction of the blower housing 10. Optionally, the length of the second receiving groove 18 is adapted to the axial length of the blower housing 10. A second light-transmitting element 124 is disposed in the second receiving groove 18, and the outer surface of the second light-transmitting element 124 is located on the same circumference as the outer surface of the peripheral wall of the blower housing 10. By setting the second receiving groove 18, the second light-transmitting element 124 is embedded in the second receiving groove 18, and the outer surface of the second light-transmitting element 124 and the outer surface of the peripheral wall of the blower housing 10 form a continuous and smooth curved surface, achieving a seamless visual integration and smooth, stepless movement. When the user holds the blower housing 10 or runs their fingers over the blower housing 10, it avoids a scratchy feeling and improves the user experience of the hair dryer. Embedding the second light-transmitting element 124 in the second receiving groove 18 makes it less likely for dust to accumulate and makes it easier to clean and wipe the peripheral wall of the blower housing 10. In addition, the second receiving groove 18 provides a precise positioning reference for the installation of the second light-transmitting element 124, simplifies the assembly process, and helps to ensure assembly accuracy and stability.

[0086] In one embodiment, see Figure 12 The light-transmitting part 12 also includes a third light-transmitting element 125. The position of the third light-transmitting element 125 is symmetrically arranged with respect to the position of the second light-transmitting element 124 relative to the blower housing 10, and one end of the third light-transmitting element 125 covers the first light-transmitting element 123. In use, the light generated by the first light-emitting part 22 can be exposed on the side of the blower housing 10 away from the handle housing 70 after passing through the first light-transmitting element 123 and the second light-transmitting element 124. At the same time, the light generated by the first light-emitting part 22 can also be exposed on the side of the blower housing 10 near the handle housing 70 after passing through the first light-transmitting element 123 and the third light-transmitting element 125, thus avoiding the "yin-yang" effect of one side of the blower housing 10 being bright and the other side being dark. In addition, when the user uses the hair dryer, they can see a complete and symmetrical light strip, which helps to improve the visibility of the hair dryer's light display.

[0087] Further, see Figure 12The outer surface of the peripheral wall of the blower housing 10 is also provided with a third receiving groove 19. The third receiving groove 19 is arranged opposite to the second light-transmitting element 124 and extends along the axial direction of the blower housing 10. The third light-transmitting element 125 is disposed in the third receiving groove 19, and the outer surface of the third light-transmitting element 125 is located on the same circumference as the outer surface of the peripheral wall of the blower housing 10. By setting the third receiving groove 19, the third light-transmitting element 125 is embedded in the third receiving groove 19, and the outer surface of the third light-transmitting element 125 and the outer surface of the peripheral wall of the blower housing 10 form a continuous and smooth curved surface, achieving a seamless visual integration and smoothness without any steps. When the user holds the blower housing 10 or runs their fingers over the blower housing 10, it avoids a scratchy feeling and improves the user experience of the hair dryer. Embedding the third light-transmitting element 125 in the third receiving groove 19 makes it less likely for dust to accumulate and makes it easier to clean and wipe the peripheral wall of the blower housing 10. In addition, the third receiving slot 19 provides a precise positioning reference for the installation of the third light-transmitting element 125, simplifies the assembly process, and helps to ensure assembly accuracy and stability.
