Description
Technical Field
[0001] This utility model relates to the technical field of hair dryer nozzle trimming devices, specifically a hair dryer nozzle trimming device that allows for quick replacement of the blade head through magnetic attraction and Hall sensor linkage. Background Technology
[0002] In scenarios such as hair styling and industrial spot cleaning, hair dryer nozzle adjustment devices require frequent replacement of different nozzle sizes to adapt to diverse needs. However, traditional devices have long suffered from three major pain points: cumbersome replacement, safety hazards, and poor adaptability. Traditional nozzles mostly use threaded rotation or snap-fit fixing methods, requiring two-hand operation to twist or press to unlock during replacement, with each replacement taking more than 30 seconds. This seriously affects operational efficiency, especially in scenarios such as hairdressers' rapid styling and efficient industrial assembly line operations. Furthermore, threads are prone to stripping due to high-temperature aging, and snaps are prone to wear and failure, leading to loose nozzle fixation and the risk of nozzle falling off during use.
[0003] More importantly, traditional devices lack a nozzle installation detection mechanism. Without nozzles, idle operation can easily lead to airflow turbulence, not only failing to achieve directional trimming but also potentially scattering the target area due to high-speed airflow. Some devices also lack high-temperature protection at the outlet, causing surface temperatures to rise after prolonged use, easily resulting in burns to operators. Furthermore, traditional devices often have straight or fixed-angle pipes, making it difficult to flexibly adjust the airflow direction, resulting in extremely low operational flexibility in complex trimming scenarios. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hair dryer nozzle trimming device that allows for quick blade replacement via magnetic attraction and Hall effect sensing linkage.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hair dryer nozzle trimming device that can quickly replace the blade head by magnetic attraction and Hall sensor linkage, comprising: a hair dryer body, wherein a pipe is provided on the hair dryer body, one end of the pipe is provided with an outlet end, and a nozzle body is arranged on the outlet end.
[0006] As a further description of the above technical solution:
[0007] The nozzle body is provided with a magnetic connection, and the periphery of the outlet end is provided with multiple sets of magnetic components, and the magnetic connection is attracted to the magnetic components.
[0008] As a further description of the above technical solution:
[0009] The nozzle body is positioned corresponding to the outlet end and is used to fix the nozzle body.
[0010] As a further description of the above technical solution:
[0011] The hairdryer body has a circuit board inside, which is used to control the start and stop of the hairdryer body.
[0012] As a further description of the above technical solution:
[0013] The hair dryer body has a Hall sensor inside, and the Hall sensor is connected to a circuit board for transmitting signals to the circuit board.
[0014] As a further description of the above technical solution:
[0015] The pipe is curved and made of polypropylene.
[0016] As a further description of the above technical solution:
[0017] The outer surface of the outlet end is coated with a high-temperature resistant metal coating.
[0018] This utility model has the following beneficial effects:
[0019] 1. The nozzle body is quickly and firmly attached to the magnetic part at the outlet end via a magnetic connector, eliminating the need for rotation or clipping. Disassembly requires only a slight pulling force, significantly reducing replacement time. At the same time, the Hall sensor senses the magnetic field and transmits a signal to the circuit board, allowing the blower to start only when the nozzle is in place, avoiding airflow turbulence caused by running without a nozzle, thus balancing convenience and safety.
[0020] 2. The curved polypropylene pipe can flexibly adjust the air outlet direction to adapt to different maintenance scenarios. The material is heat-resistant and lightweight, and the smooth inner wall reduces airflow resistance. The high-temperature resistant metal coating on the outer surface of the outlet end can not only insulate against high temperature to prevent burns, but also resist loading and unloading friction, extend the service life of components, and solve the problems of fixed direction and easy damage at high temperatures in traditional devices.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0027] Example 1:
[0028] like Figures 1 to 2 As shown in the figure, the hairdryer nozzle trimming device with magnetic attraction and Hall sensor linkage for quick blade replacement provided in this embodiment includes: hairdryer body 1, hairdryer body 1 is provided with pipe 12, one end of pipe 12 is provided with outlet end 2, and nozzle body 3 is arranged on outlet end 2.
[0029] In this embodiment, the hair dryer body, the nozzle body, and the circuit board constitute a hair dryer nozzle trimming device with magnetic attraction and Hall sensor linkage that allows for quick replacement of the blade head, as described in this application.
[0030] Understandable, Figure 1 The diagram only schematically illustrates some of the components included in the hair dryer nozzle trimming device for changing blades. The actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, the nozzle trimming device for hair dryers with replaceable blades can also include features compared to... Figure 1More or fewer parts.
[0031] It should also be understood that the Hall sensors are all purchased from the market and are common knowledge in this field. They are only used and not modified, so the control method and circuit connection will not be described in detail.
[0032] Furthermore, in this embodiment, the nozzle body 3 is connected to the outlet end 2 and fixed by a magnetic structure. The airflow generated by the blower body 1 is ejected from the nozzle body 3 through the pipe 12 and the outlet end 2, achieving directional blowing and trimming. The curved pipe 12 can adjust the airflow direction to adapt to different usage scenarios. The curved pipe improves operational flexibility, the polypropylene material is heat-resistant and lightweight, and the nozzle and outlet end are precisely connected to avoid airflow leakage.
[0033] Specifically, the nozzle body 3 is provided with a magnetic connection 31, and the periphery of the outlet end 2 is provided with multiple sets of magnetic components 32, and the magnetic connection 31 and the magnetic components 32 are attracted to each other.
[0034] In this embodiment, when installing the nozzle, the magnetic connection 31 of the nozzle body 3 and the magnetic component 32 of the outlet end 2 are attracted and bonded by opposite poles, achieving quick positioning and fixation; during disassembly, a slight pulling force is applied to separate them, completing the nozzle replacement. Magnetic installation requires no rotation or snap-fit, shortens replacement time, has stable adsorption force, avoids nozzle falling off during use, and is suitable for frequent replacement needs.
[0035] Specifically, the nozzle body 3 is positioned corresponding to the outlet end 2, and is used to fix the nozzle body 3.
[0036] As a preferred implementation method, during docking, the convex ring guides the nozzle body 3 to precisely fit the outlet end 2, and the magnetic attraction structure further fixes it to ensure that the central axes of the two coincide, avoid air outlet deviation, ensure concentrated airflow in the trimming area, and improve the shaping accuracy.
[0037] Specifically, the hair dryer body 1 has a circuit board 4 inside, which is used to control the start and stop of the hair dryer body 1.
[0038] In this embodiment, after the Hall sensor detects the nozzle installation signal, it transmits it to the circuit board 4, which triggers the motor to start. After the nozzle is removed, the signal is interrupted, and the circuit board 4 controls the motor to stop after a delay, thus achieving intelligent start-stop. Intelligent start-stop avoids idling without a nozzle, and the integrated circuit board design reduces circuit failures and extends the service life compared to distributed circuits.
[0039] Specifically, a Hall sensor is arranged inside the hair dryer body 1, and the Hall sensor is connected to the circuit board 4 for transmitting signals to the circuit board 4.
[0040] With this configuration, when the nozzle is installed, the magnetic field of the magnetic connection 31 acts on the Hall sensor, which generates an electrical signal and transmits it to the circuit board 4. After recognizing the signal, the circuit board 4 confirms that the nozzle is installed and allows the motor to start. When there is no nozzle, there is no magnetic field signal, and the motor is locked and cannot start. This achieves intelligent nozzle recognition and avoids airflow turbulence caused by the absence of a nozzle.
[0041] Specifically, pipe 12 is curved and made of polypropylene.
[0042] The polypropylene material is well-suited to the high-temperature airflow of hair dryers, its smooth inner wall reduces airflow resistance, and its curved structure guides airflow, minimizing pressure loss. Airflow resistance is lower than that of ordinary plastic pipes, and its temperature resistance meets long-term usage requirements with no risk of deformation or cracking.
[0043] Specifically, the outer surface of the outlet end 2 is coated with a high-temperature resistant metal coating.
[0044] In this embodiment, when the hair dryer is working, the outlet end 2 experiences a temperature increase due to the conduction of high-temperature airflow. The high-temperature resistant metal coating isolates the heat from being transferred to the outside and simultaneously resists frictional wear during nozzle installation and removal. The coating lowers the temperature of the outer surface of the outlet end, preventing burns; it also increases friction life and extends the life of the component.
[0045] In actual use, the magnetic connector 31 of the nozzle body 3 and the magnetic component 32 of the blower outlet 2 are attracted by opposite poles, and can be quickly fixed without rotation or clipping. When disassembling, a slight pulling force can be applied to separate them, which greatly shortens the nozzle replacement time and is suitable for frequent head replacement needs.
[0046] The Hall sensor inside the hair dryer body 1 senses the magnetic field, generates a signal, and transmits it to the circuit board 4. The circuit board only allows the hair dryer to start when the nozzle is installed in place, avoiding airflow turbulence caused by running without a nozzle and ensuring safe use.
[0047] The curved polypropylene pipe 12 allows for flexible adjustment of the air outlet direction, while the high-temperature resistant metal coating at the outlet end 2 isolates high temperatures to prevent burns, ensuring stable airflow output while improving operational safety and scenario adaptability.
[0048] The hair dryer body 1 is equipped with a Hall sensor; the sensor is electrically connected to the controller, which is the central hub of the entire system. It is responsible for receiving instructions, monitoring the status, and controlling the actions of each component. By pre-setting a program or adjusting parameters in real time, the automatic control of the hair dryer body 1 can be realized. The Hall sensor monitors the circuit board 4 in real time and transmits the sensed signal to the controller, which controls the operation of the hair dryer body 1.
[0049] It should be noted that the controller can be a conventional known device that is controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific embodiments of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.
[0050] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
