[0001] This utility model relates to the field of household appliance technology, and in particular to a hair dryer. Background Technology

[0002] A hair dryer typically includes a nozzle, a fan assembly, and a heating element, with a handle for the user to hold. The fan and heating elements are located inside the nozzle. The fan assembly draws in outside air and blows it out from the nozzle's outlet (cold air), or the heating element heats the air and then blows it out from the nozzle's outlet (hot air). A display screen can be installed on the nozzle to show information such as temperature and airflow.

[0003] However, in related technologies, the display screen of the hair dryer is located on the outer circumference of the blower casing. This installation method encroaches on the internal space of the blower casing, which is typically circular, and the internal fan components are also circular in design to fit the casing. The display screen placement disrupts this fit, making it inconvenient for the layout and installation of the internal fan and heating components. Furthermore, the display screen on the outer circumference of the blower casing is also difficult for the user to see during use. Utility Model Content

[0078] The hairdryer of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0079] Reference Figures 1 to 8 As shown, the hair dryer provided according to the embodiment of the present utility model includes a blower 10, a blower assembly 20, a display screen 30, and an air inlet cover assembly 40.

[0080] Specifically, the ventilation duct 10 has an air inlet and an air outlet. The ventilation duct 10 can be made of materials with high temperature resistance, corrosion resistance, and good strength. For example, the ventilation duct 10 is typically made of high-performance engineering plastics, such as polycarbonate (PC) or specially treated nylon plastic, or aluminum alloy. These materials not only have high heat resistance and can withstand high-temperature environments, but also have good impact resistance, wear resistance, and molding processing capabilities, ensuring the stable performance of the ventilation duct 10 during long-term use.

[0081] The fan assembly 20 is located inside the air duct 10 and adjacent to the air inlet. It draws in outside air and delivers it to the air outlet. During this process, the air passes through the heating assembly 70, which can either heat the air to form hot air or keep it as cold air without heating.

[0082] The display screen 30 is located at the air inlet end and on the side of the blower assembly 20 away from the air outlet end along the axial direction of the blower duct 10. This arrangement avoids placing the display screen 30 on the outer peripheral surface of the blower duct 10, thus avoiding occupation and interference with the internal structure of the blower duct 10. The display screen 30 can display information such as temperature and airflow, allowing consumers to intuitively observe the working status of the blower during use, improving the convenience and safety of operation.

[0083] The air inlet cover assembly 40 is detachably mounted on the air inlet end. The air inlet cover assembly 40 covers the display screen 30, allowing external air to flow into the air duct 10 while also exposing the display screen 30. In other words, the air inlet cover assembly 40 allows external air to flow smoothly into the air duct 10, ensuring the blower assembly 20 can draw in sufficient air, while also partially exposing the display screen 30 for easy monitoring of data information during use. Furthermore, the detachable nature of the air inlet cover assembly 40 facilitates later maintenance and cleaning, effectively preventing dust and other impurities from clogging the air inlet end, further ensuring the long-term stability and service life of the blower.

[0084] According to the hairdryer provided in this embodiment of the present invention, the display screen 30 is arranged at the air inlet end of the air duct 10 and is axially positioned on the side away from the air outlet end of the fan assembly 20. At the same time, a detachable air inlet cover assembly 40 is used to cover the display screen 30. This arrangement does not encroach on the space inside the air duct 10 used to accommodate the fan assembly 20 and the heating assembly 70, while ensuring that external air can flow smoothly into the air duct 10 and that the display screen 30 is exposed at the air inlet end. This makes it easy for the user to observe the display screen during use, thereby simplifying the structural layout of the internal components and improving the user experience.

[0085] It is understood that the hair dryer may also include a heating element 70, which is located inside the blower duct 10 and adjacent to the air outlet. When the blower assembly 20 draws in external air from the air inlet and blows it to the air outlet, if hot air is required, the heating element 70 is turned on to heat the air. The heated air forms hot air and is blown out from the outlet to achieve the function of blowing hot air.

[0086] Reference Figures 2 to 3 As shown, in one embodiment of this utility model, the fan assembly 20 includes a fan bracket 201 and a blower 202. The fan bracket 201 is fixed inside the air duct 10. Exemplarily, the fan bracket 201 is formed to fit the radial cross-section of the air duct 10, ensuring that the fan bracket 201 is snapped into the air duct 10 and remains relatively fixed to the air duct 10. The blower 202 is installed inside the fan bracket 201, with the air inlet side of the blower 202 facing the air inlet end of the air duct 10, ensuring that when the blower 202 is working, air is introduced from the air inlet end and blown out to the air outlet end.

[0087] The fan bracket 201 has multiple support legs 2011 near the air inlet end. These support legs 2011 are spaced apart circumferentially along the fan duct 10, and each support leg 2011 extends axially away from the air outlet end along the fan duct 10. The display screen 30 is fixed to the multiple support legs 2011 and forms an air inlet cavity P20 between itself and the fan bracket 201.

[0088] The display screen 30 is mounted on the support legs 2011 on the fan bracket 201, creating a certain gap between the display screen 30 and the fan bracket 201, thus forming an air inlet cavity P20. This ensures that the air introduced by the air inlet cover assembly 40 can flow smoothly into the air inlet cavity P20, and then be delivered to the air outlet by the blower 202. In other words, the existence of this air inlet cavity P20 ensures that the air inlet of the duct 10 can not only ensure smooth airflow, but also maintain good visibility of the display screen 30 without being obstructed.

[0089] The air inlet cover assembly 40 is provided with an air inlet hole H41a for introducing external air into the air inlet chamber P20. This air inlet cover assembly 40 not only serves to prevent dust and foreign objects from being sucked in, but also allows external air to be smoothly introduced through the air inlet hole H41a, resulting in a more even air distribution and thus improving the overall air delivery effect and airflow efficiency of the unit.

[0090] In this embodiment, the fan assembly 20 is a combination of a fan bracket 201 and a blower 202. Multiple axially extending legs 2011 are provided on the fan bracket 201 for mounting the display screen 30. Based on this, the air inlet cavity P20 and the air inlet hole H41a provided on the air inlet cover assembly 40 work together to effectively introduce external air into the air duct 10. This not only ensures the efficient operation of the blower 202, but also allows the display screen 30 to be reasonably arranged without encroaching on the internal functional area, maintaining a good visual effect. This significantly improves airflow efficiency, structural stability, and the overall user experience of the blower.

[0091] Reference Figures 2 to 3 As shown, in one embodiment of the present invention, the air inlet cover assembly 40 includes an air inlet cover 401. One end of the air inlet cover 401 is an open end and is detachably connected to the air inlet end. The detachable nature facilitates the disassembly and assembly of the air inlet cover 401, thereby facilitating the cleaning of the air inlet cover 401 and the interior of the air inlet end, such as cleaning the dust in the air inlet hole H41a on the air inlet cover 401, and cleaning the dust, hair, etc. inside the air inlet end.

[0092] The other end of the air inlet shroud 401 has a window H41b for displaying the display screen 30. By displaying the display screen 30 located at the air inlet end, the display screen 30 can be more easily seen during use, resulting in better visibility.

[0093] There are multiple air inlets H41a, which are spaced apart along the circumference of the air inlet cover 401. This ensures that external air can flow into the internal air inlet cavity P20 evenly and stably.

[0094] Reference Figure 3 As shown, in one embodiment of the present invention, the air inlet end is further provided with a dustproof mesh cylinder 50, which is sleeved outside the air inlet cavity P20 and located inside the air inlet cover 401.

[0095] In this embodiment, the dustproof mesh cylinder 50 ensures that external air can be smoothly drawn into the air inlet cavity P20, while also providing dust protection. This prevents lint, hair, dust, and other debris from being drawn into the fan assembly 20, thereby improving the safety of the hair dryer.

[0096] Preferably, the dustproof screen 50 is plugged into the air inlet. This plug-in connection method facilitates the disassembly and assembly of the dustproof screen 50, thereby facilitating subsequent cleaning and maintenance. When cleaning is required, the air inlet cover 401 can be removed first, and then the dustproof screen 50 can be removed to clean the dust and other debris on the dustproof screen 50. The cleaning operation is simple and convenient.

[0097] To improve the reliability of the connection between the dustproof mesh cylinder 50 and the air inlet, a rib structure can be provided between the dustproof mesh cylinder 50 and the air inlet. When one end of the dustproof mesh cylinder 50 is inserted into the air inlet, the rib structure between the two fits together, thereby reliably fixing the dustproof mesh cylinder 50 to the air inlet.

[0098] Reference Figures 2 to 3 As shown, in one embodiment of this utility model, the air inlet cover assembly 40 further includes an air inlet bracket 402. One end of the air inlet bracket 402 is connected to the air inlet end, and the other end of the air inlet bracket 402 has a light-transmitting cover 403. The light-transmitting cover 403 is located on the side of the air duct 10 axially opposite to the display screen 30 away from the air outlet end, and is used to display information on the display screen 30. That is, the data information on the display screen 30 can be seen from the outside through the light-transmitting cover 403. The light-transmitting cover 403 can isolate and protect the display screen 30 while maintaining visibility.

[0099] An air inlet hood 401 is detachably mounted on the air inlet bracket 402. A light-transmitting cover 403 is located in the window H41b. The peripheral wall of the air inlet bracket 402 has multiple perforated openings H42a opposite to the air inlet chamber P20. The multiple perforated openings H42a are arranged at intervals along the circumference of the air inlet bracket 402 and communicate with the air inlet holes H41a. Externally introduced air enters the shaft through the air inlet holes H41a on the air inlet hood 401, passes through the perforated openings H42a on the peripheral wall of the air inlet bracket 402 and the dustproof mesh cylinder 50, and enters the air inlet chamber P20.

[0100] In this embodiment, by configuring an air inlet bracket 402 and a light-transmitting cover 403 on the air inlet cover assembly 40, the air inlet cover 401 and the air inlet bracket 402 can be detachably combined, facilitating the disassembly and assembly of the air inlet cover 401. At the same time, the light-transmitting cover 403 also provides protection for the display screen 30.

[0101] Reference Figure 3 As shown, in one embodiment of this utility model, the outer circumferential surface of the air inlet bracket 402 is provided with a plurality of L-shaped latches H42b at circumferential intervals, and the inner circumferential surface of the air inlet cover 401 is provided with a plurality of rotating buckles 4011. The plurality of rotating buckles 4011 correspond one-to-one with the plurality of L-shaped latches H42b. When the air inlet cover 401 is fitted onto the air inlet bracket 402, the air inlet cover 401 is rotated by a predetermined angle, and the rotating buckles 4011 engage with the L-shaped latches H42b.

[0102] During assembly, when the air inlet hood 401 is fitted onto the air inlet bracket 402, the operator first aligns the rotating buckle 4011 of the air inlet hood 401 with and inserts it into the L-shaped bayonet H42b of the air inlet bracket 402. Then, by rotating the air inlet hood 401 to a predetermined angle, the rotating buckle 4011 and the L-shaped bayonet H42b are precisely engaged. This rotation ensures that the air inlet hood 401 and the air inlet bracket 402 remain locked in the axial direction after connection, thus maintaining a reliable connection and preventing the air inlet hood 401 from easily detaching from the air inlet bracket 402.

[0103] This embodiment achieves a quick, precise, and secure assembly connection between the air inlet cover 401 and the air inlet bracket 402 through multiple L-shaped bayonets H42b on the air inlet bracket 402 and corresponding rotating buckles 4011 on the air inlet cover 401. While ensuring assembly stability, it also takes into account the convenience of subsequent disassembly and maintenance.

[0104] Preferably, the air inlet bracket 402 is snap-fitted to the air inlet end, and the dustproof mesh cylinder 50 is located inside the air inlet bracket 402 and is secured by the air inlet bracket 402. The snap-fit ​​connection between the air inlet bracket 402 and the air inlet end provides a reliable mechanical fixing effect. Furthermore, the dustproof mesh cylinder 50 is inside the air inlet bracket 402 and secured by it; for example, the other end of the dustproof mesh cylinder 50 is inserted into a slot in the air inlet bracket 402. This ensures that the dustproof mesh cylinder 50 is more reliably and stably fixed.

[0105] Reference Figures 1 to 4 As shown, in some embodiments of this utility model, the air outlet end is pluggably connected to an air outlet nozzle, which includes at least one of a flat nozzle 60 and a flared nozzle 61. Users can choose the appropriate air outlet nozzle as needed.

[0106] The flat nozzle 60 has a thinner and more uniform air outlet, which can form a concentrated and straight airflow when air is emitted, making it suitable for situations that require precise directional airflow, such as styling or localized rapid drying of hair. The trumpet nozzle 61, on the other hand, uses a trumpet-shaped diffuser structure to form a wider and more dispersed airflow at the air outlet, suitable for even drying of hair or achieving a gentle airflow effect.

[0107] By implementing a plug-in connection design, the air outlet can be flexibly matched with either a flat nozzle 60 or a flared nozzle 61, allowing users to choose the most suitable air outlet according to their own needs. This not only achieves the convenience of modular design but also improves the overall user experience and reliability of the hair dryer.

[0108] For example, the nozzle 61 has multiple protruding air vents H61 inside. This type of nozzle can be inserted into the hair to blow-dry it while combing, which is very effective in drying hair quickly, especially suitable for long hair care.

[0109] Reference Figures 5 to 6 As shown, in some embodiments of this utility model, the air duct 10 includes an upper shell 10a, a lower shell 10b, and two decorative strips 10c. The two decorative strips 10c are respectively fixed to both sides of the lower shell 10b by screws. The upper shell 10a and the two decorative strips 10c are fastened together to form the air duct. The fan bracket 201 is fixed inside the lower shell 10b by screws.

[0110] In this embodiment, the air duct 10 is composed of an upper shell 10a, a lower shell 10b, and two decorative strips 10c, which facilitates the assembly of each component. In addition, the two decorative strips 10c are located on both sides of the air duct to serve a decorative purpose and improve the appearance.

[0111] Reference Figure 2 , Figures 5 to 6 As shown, in one embodiment of the present invention, the hair dryer further includes a heating component 70, which includes a heat dissipation cylinder 701 and a heating element disposed within the heat dissipation cylinder 701. The heat dissipation cylinder 701 is disposed within the lower shell 10b, and the outer wall of the heat dissipation cylinder 701 is provided with ribs 7011. The decorative strip 10c is provided with an inwardly protruding buckle 101c, which is pressed against the ribs 7011 and is snapped together with the upper shell 10a.

[0112] During assembly, after the heating component 70 is installed inside the lower housing 10b, the two decorative strips 10c are respectively secured to both sides of the lower housing 10b with screws. Simultaneously, the snaps on the decorative strips 10c are pressed against the ribs 7011 of the heat sink 701. This ensures the reliability of the heating component 70's fixation. Furthermore, the lower housing 10b, decorative strips 10c, heating component 70, and upper housing 10a form a fixed relationship with each other, improving the reliability and stability of the various components of the hair dryer. In addition, the components are assembled sequentially during the assembly process, making assembly simple and convenient.
