Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, specifically a twist-type hair dryer. Background Technology

[0002] Hair dryers are commonly used devices in daily personal care and household cleaning. Their core functions revolve around airflow drive and temperature control. The motor drives the fan blades to generate airflow, and the heating element enables the switching between hot and cold air to meet diverse needs such as drying and styling.

[0003] Existing hair dryers still have certain shortcomings in practical use: First, most products use traditional metal or plastic materials, which makes it difficult to balance structural strength and overall lightweight design. Coupled with the wired power supply design, they are not portable and cannot meet the needs of mobile use. Second, the angle of the nozzle is mostly fixed, which makes it difficult to adapt to the angle requirements of different use scenarios. They are not portable enough and their practicality needs to be improved.

[0004] In view of this, we propose a twist-type hair dryer. Utility Model Content

[0005] The purpose of this invention is to provide a twist-type hair dryer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A rotary hair dryer includes a handle and a blower casing. The handle has a switch and a wireless battery internally mounted. An asynchronous motor is fixedly installed on the inner wall of the handle, and a drive gear is fixedly installed on the output shaft of the asynchronous motor. A rotating column is rotatably mounted inside the handle via a bearing. The outside of the rotating column is fixedly connected to the inside of one end of the blower casing. A rotating cylinder is fixedly installed inside the center of the rotating column, and a driven gear is fixedly installed outside the rotating cylinder. The drive gear meshes with the driven gear. An air duct is formed inside the blower casing, communicating with the inside of the rotating cylinder. A brushless motor is fixedly installed on the inner wall of the blower casing, and a bionic fan blade is fixedly installed at the output end of the brushless motor. A bracket is fixedly installed on the inner wall of the blower casing, and a heating element is fixedly installed on the bracket. An air inlet is formed on the blower casing.

[0007] In a further embodiment, both the handle and the air duct are integrally die-cast from recycled magnesium alloy made of negative carbon material, which ensures structural strength while reducing the weight of the entire machine.

[0008] In a further embodiment, the switching element includes a wind speed switch, a temperature switch, and a rotation amplitude switch.

[0009] A further solution also includes an intelligent temperature control system, which comprises a multi-channel NTC sensor and a PID algorithm module. The multi-channel NTC sensor is used to detect the temperature at the air outlet of the duct, and the PID algorithm module controls the temperature based on the detected temperature.

[0010] In a further embodiment, a filter plate is snapped onto the air duct, the filter plate is located inside the air inlet, and a protruding post is fixedly installed in the center of the filter plate to better prevent external impurities from entering the air duct.

[0011] In a further embodiment, the handle is provided with heat dissipation holes, which are connected to the internal cavity of the handle for better heat dissipation.

[0012] In a further embodiment, a baffle is fitted inside the end of the air duct furthest from the handle to better prevent external impurities from entering the air duct.

[0013] Compared with the prior art, this utility model provides a twist-type hair dryer, which has the following beneficial effects: 1. This twist-type hair dryer, designed for greater portability and practicality, features a brushless motor that rotates the bionic fan blades. Combined with the speed and temperature controls and the heating element on the stand, external airflow is drawn into the nozzle through the air inlet, achieving hurricane-level wind speeds and producing both hot and cold air. Made from recycled magnesium alloy using negative carbon materials, it is integrally die-cast to ensure structural strength while reducing overall weight. The wireless battery further enhances its battery life. The rotation angle switch activates the asynchronous motor, causing the drive gear to rotate. This, along with the driven gear, drives the rotating column and cylinder, rotating the nozzle on the handle. This allows for multi-angle adjustment, improving operational flexibility and adapting to different usage scenarios. The ductwork facilitates cable management, further enhancing the hair dryer's portability and practicality.

[0014] 2. To enhance the practicality of this twist-type hair dryer, an intelligent temperature control system is incorporated. This system includes a multi-channel NTC sensor and a PID algorithm module. The multi-channel NTC sensor detects the temperature at the air outlet of the blower, while the PID algorithm module achieves precise temperature control within ±1℃ based on the detected temperature. Combined with a filter plate and baffle strip, this system better prevents external impurities from entering the blower. The protruding posts facilitate the installation and removal of the filter plate, and the ventilation holes improve heat dissipation, thereby enhancing the practicality of the hair dryer.

[0019] Please see Figures 1-7 This utility model provides a technical solution: A twist-type hair dryer includes a handle 1 and a blower tube 2. The handle 1 is equipped with a switch 3. A wireless battery 4 is snapped into the handle 1. An asynchronous motor 5 is fixedly installed on the inner wall of the handle 1. A drive gear 6 is fixedly installed on the output shaft of the asynchronous motor 5. A rotating column 7 is rotatably installed inside the handle 1 via a bearing. The rotating column 7 is fixedly connected to the inside of one end of the blower tube 2. A rotating cylinder 8 is fixedly installed inside the center of the rotating column 7. A driven gear 9 is fixedly installed on the outside of the rotating cylinder 8. The drive gear 6 meshes with the driven gear 9. An air duct 10 is opened inside the blower tube 2 and is connected to the inside of the rotating cylinder 8. A brushless motor 11 is fixedly installed on the inner wall of the blower tube 2. A bionic fan blade 12 is fixedly installed at the output end of the brushless motor 11. A bracket 13 is fixedly installed on the inner wall of the blower tube 2. A heating element 14 is fixedly installed on the bracket 13. An air inlet 15 is opened on the blower tube 2.

[0020] In one embodiment of this utility model, both the handle 1 and the air duct 2 are integrally die-cast from recycled magnesium alloy made of negative carbon material, which ensures structural strength and reduces the weight of the whole machine. In addition, the switch 3 includes a wind speed switch (to adjust the speed of the brushless motor 11), a temperature switch (to adjust the heating power of the heating element 14), and a rotation amplitude switch (to control the asynchronous motor 5). In addition, it also includes an intelligent temperature control system, which includes a multi-channel NTC sensor and a PID algorithm module. The multi-channel NTC sensor is used to detect the temperature of the air outlet of the air duct 2, and the PID algorithm module controls the temperature by ±1℃ based on the detected temperature.

[0021] In one embodiment of this utility model, a filter plate 16 is snapped onto the air duct 2. The filter plate 16 is located inside the air inlet 15. A protrusion 17 is fixedly installed in the center of the filter plate 16 to better prevent external impurities from entering the air duct 2. In addition, a heat dissipation hole 18 is provided on the handle 1. The heat dissipation hole 18 is connected to the internal cavity of the handle 1 to better dissipate heat. Furthermore, a baffle 19 is snapped onto the end of the air duct 2 away from the handle 1 to better prevent external impurities from entering the air duct 2.

[0022] Working Principle: First, the wireless battery 4 provides stable power support for the entire device. The switch 3, as the core of operation, includes a fan speed switch, a temperature switch, and a rotation amplitude switch, each corresponding to different function controls. When a working command is triggered by the switch 3, the brushless motor 11 starts. This brushless motor 11 is an ultra-high-speed brushless motor with a speed of 120,000 rpm. Its output drives the bionic fan blades 12 to rotate at high speed, generating strong suction. Combined with the cavity structure of the air duct 2, external airflow is quickly drawn into the air duct 2 through the air inlet 15, forming a hurricane-level airflow. At this time, if the switch 3 is turned on... The temperature setting switch activates the heating element 14 on the bracket 13. When current passes through the heating wire of the heating element 14, electrical energy is converted into heat energy, and the air flowing through the heating element 14 is rapidly heated to form hot air. If the temperature setting switch is turned off, the heating circuit is shut off, and the airflow flows directly through the inside of the air duct 2, blowing out cold air. The air temperature can be controlled by adjusting the power of the heating wire of the heating element 14 to meet different usage needs. The whole machine is made of recycled magnesium alloy with negative carbon material and integral die casting. While ensuring the structural strength of the handle 1 and the air duct 2, the weight of the whole machine is greatly reduced, improving the portability of the device, and the battery life of the wireless battery 4 is enhanced. Control signals are sent via the rotation amplitude switch in switch 3. Upon receiving the signal, the asynchronous motor 5 starts, and its output shaft drives the drive gear 6 to rotate synchronously. The drive gear 6 meshes with the driven gear 9, transmitting power to the rotating drum 8. The rotating drum 8 is fixedly connected to the rotating column 7, which in turn drives the rotating column 7 to rotate the air duct 2 on the handle 1, achieving multi-angle free adjustment to meet the blowing angle requirements of different usage scenarios and further ensuring the ease of use of the equipment. At the same time, the air duct 10 inside the air duct 2 provides a dedicated cable routing channel to prevent cable entanglement from affecting the rotation function. Precise temperature control relies on an intelligent temperature control system (not shown in the figure). This system includes a multi-channel NTC sensor and a PID algorithm module. The multi-channel NTC sensor detects the temperature data of the air outlet of the air duct 2 in real time and feeds the data back to the PID algorithm module. The PID algorithm module calculates the difference between the preset temperature and the detected temperature, outputs a control signal, and precisely adjusts the heating power of the heating element 14 to achieve precise temperature control of ±1℃, avoiding excessively high or low temperatures that may affect the user experience. The filter plate 16 on the air duct 2 is located inside the air inlet 15. It can intercept dust, hair and other impurities in the external airflow and prevent impurities from entering the air duct 2 and damaging components such as the brushless motor 11 and the bionic fan blade 12. The baffle 19 further reinforces the protection and prevents large particles of impurities from entering from the air outlet side of the air duct 2. The protrusion 17 is fixed in the center of the filter plate 16, which makes it easy for users to quickly disassemble and install the filter plate 16 for cleaning or replacement, improving the convenience of maintenance. The heat dissipation hole 18 on the handle 1 is connected to the internal cavity of the handle 1, which can quickly dissipate the heat generated by components such as the asynchronous motor 5 and the wireless battery 4 during operation, preventing the machine body from overheating and affecting the service life of the equipment. In addition, the switch 3, the asynchronous motor 5, the brushless motor 11 and the heating element 14 are all electrically connected to the intelligent temperature control system and the wireless battery 4 to ensure smooth signal transmission and stable power supply of each component, and to ensure the efficient and coordinated operation of all functions of the whole machine.

[0023] Among them, the switch 3, asynchronous motor 5, brushless motor 11, and heating element 14 are all electrically connected to the intelligent temperature control system and wireless battery 4. The brushless motor 11 is an ultra-high-speed brushless motor with a speed of 120,000 rpm. When current passes through the heating wire of the heating element 14, electrical energy is converted into heat energy, and the air flowing through it is heated to form hot air. If the heating circuit is disconnected, cold air is blown out. The air temperature can be controlled by adjusting the power of the heating wire. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all connected by conventional methods such as riveting and welding that are mature in the prior art. The standard parts are all of conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.

[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
