Description

Technical Field

[0001] This utility model relates to the technical field of sculptors, and in particular to a folding sculptor that can dynamically measure distance and adjust temperature. Background Technology

[0002] Hair stylers are household appliances that people use frequently in their daily lives. They generally consist of a hair dryer body and various nozzles. The hair dryer body generates heat through a heating element, and the airflow generated by a high-speed motor expels the heat through the air outlet, allowing the hot air to style our hair.

[0003] Current styling tools are not compact enough, taking up a lot of space and making them inconvenient to store and carry, thus failing to meet users' daily storage and portability needs.

[0004] Chinese Patent No. CN221129102U, authorized and published on June 14, 2024, discloses a foldable hair dryer. It includes a housing comprising a horizontal shell and a vertical shell connected together. The horizontal shell has an air outlet. The vertical shell includes a first shell and a second shell, with one end of the first shell connected to the horizontal shell and the other end connected to the second shell. A rotating structure is disposed between the first shell and the second shell for rotatably connecting them. A nozzle is connected to the air outlet of the horizontal shell. When the hair dryer is folded, the second shell and the horizontal shell are arranged at a preset angle. This disclosure utilizes the rotatable connection between the first and second shells to fold the second shell, creating a preset angle between the second shell and the horizontal shell, effectively reducing the space occupied by the hair dryer and facilitating its storage and portability.

[0005] The aforementioned patent solves the problem of inconvenient storage and carrying of styling tools on the market. However, during use, if air is continuously supplied to a certain area of ​​the head or the air outlet is too close to the scalp, the heat generated by the heating element will often accidentally burn the scalp, or even cause burns, which is not conducive to safe use. Utility Model Content

[0006] The present invention aims to overcome the shortcomings of existing styling tools that can easily cause burns to the scalp and are not conducive to safe use, and provides a foldable styling tool that is safe to use and can dynamically measure distance and adjust temperature.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A folding molded object with dynamic ranging and temperature adjustment, comprising: The cylinder body has an air inlet at one end and an air outlet at the other end. The handle is hinged to the outer wall of the cylinder body and has a main control board inside. Buttons and power cords that are electrically connected to the main control board are located on the outside of the handle. The handle is hinged to the cylinder body to realize the folding function of the handle, so as to facilitate the carrying of the whole shape. According to actual needs, a negative ion high-voltage pack can also be set inside the handle. The motor is detachably and fixedly connected to the air inlet and electrically connected to the main control board; The heating element is detachably and fixedly connected to the air outlet and electrically connected to the main control board. The MCU is detachably fixed inside the cylinder and located on the side of the motor. The MCU is communicatively connected to the main control board. The air outlet is located at the edge of the air outlet end and corresponds to the heating element; The intelligent sensing module is detachably and fixedly connected to the center of the air outlet and isolated from the air outlet. It includes a ranging module and a temperature measuring module, both of which are communicatively connected to the MCU.

[0008] The temperature measurement module senses the surface temperature of the hair, and the distance measurement module measures the distance from the scalp to the air outlet. Both signals are processed and transmitted to the MCU, which analyzes and processes them in real time to determine the temperature adjustment range. Simultaneously, it sends a command to the main control board, which outputs the signal to the heating element. Therefore, by measuring the scalp surface temperature and the distance between the air outlet and the scalp in real time, the entire fan temperature is automatically adjusted to prevent scalp burns and ensure safe use. The intelligent sensing module is connected to the center of the air outlet and isolated from it, which helps improve the measurement accuracy of the distance and temperature measurement modules.

[0009] Preferably, the intelligent sensing module further includes a PCBA board, an MCU chip, a lighting display module, and a cover plate. The lighting display module, ranging module, temperature measuring module, and MCU chip are all fixed to the PCBA board and electrically connected to it. The PCBA board is electrically connected to the main control board. The lighting display module, ranging module, and temperature measuring module are all located between the cover plate and the PCBA board. One side of the cover plate is detachably and fixedly connected to the PCBA board and is connected to the center of the air outlet with a snap fastener. A lighting lens matching the lighting display module is embedded in the cover plate. A ranging lens matching the ranging module is integrated on the cover plate. A light-transmitting plate corresponding to the ranging lens is fixed on the other side of the cover plate. Both the light-transmitting plate and the cover plate are provided with temperature measuring holes corresponding to the temperature measuring module. The lighting display module, ranging module, and temperature measurement module can be arranged in a triangular pattern on the PCBA board, but are not limited to this. For the lighting display module, the concept of lens splicing is used to realize the function of light dispersion display effect of micro-structure. The lighting display module, ranging module, and temperature measurement module are integrated into a single module to facilitate product expansion and upgrades. The MCU chip is used for information processing and analysis of the whole machine.

[0010] Preferably, the temperature measurement module is an infrared thermopile temperature measurement module, with an aluminum tube encasing it to reduce the impact of the surrounding environment. The ranging module is preferably an infrared TOF ranging module. Currently, there are three types of ranging modules on the market: laser ranging, infrared ranging, and ultrasonic ranging. Laser ranging has poor environmental adaptability, is susceptible to rain, fog, and glare, and is the most expensive, making it unsuitable for hair dryers. Ultrasonic ranging is also unsuitable because temperature and wind speed changes affect its accuracy. Infrared TOF is susceptible to strong light, but hair dryers are used in environments without strong light, so it is not affected. Furthermore, it is inexpensive, consumes little power, and is small in size, making it the most suitable ranging module. However, single infrared TOF ranging has the drawback of low measurement accuracy, only reaching the centimeter level. Therefore, using a single TOF ranging module for temperature control results in low temperature control accuracy due to the low accuracy of the ranging. Adding a real-time temperature measurement module allows for better temperature calibration and timely adjustments, ensuring accurate temperature control.

[0011] Preferably, the heating element has a hollow channel and several hot air ducts corresponding to the air outlets. The hollow channel is located at the center of the heating element and is isolated from the hot air ducts. The hot air ducts are evenly distributed around the hollow channel along the edge of the heating element. One end of the hollow channel is close to the motor and has several wiring holes. The other end of the hollow channel is away from the motor and located at the center of the air outlet. The end of the hollow channel away from the motor has a mounting slot that matches the intelligent sensing module. The intelligent sensing module is snap-fitted into the mounting slot. This dedicated hollow channel design facilitates wiring at the rear end and separates the hot air ducts of the heating element, reducing the impact of high temperatures on the intelligent sensing display device.

[0012] Preferably, the heating frame is equipped with a heating wire, an NTC temperature sensor, a thermal fuse, and a temperature controller. These components are all fixed within the hot air duct. The NTC temperature sensor is communicatively connected to the MCU, and the heating wire, thermal fuse, and temperature controller are connected in series and electrically connected to the main control board. The NTC temperature sensor measures the temperature in the airflow channel near the air outlet in real time; the thermal fuse and temperature controller protect the entire molding unit from high-temperature damage.

[0013] Preferably, an inner cylinder is detachably fixed inside the cylindrical body, the motor is detachably fixed inside one end of the inner cylinder, the heating element is detachably fixed inside the other end of the inner cylinder, and the MCU is detachably fixed to the outer wall of the inner cylinder and located inside the cylindrical body.

The MCU is placed outside the inner cylinder and inside the cylindrical body, and is attached to the heat dissipation aluminum fin located between the motor and the heating element. The MCU chip dissipates heat through contact between the cold air surface of the motor and the heat dissipation aluminum fin.

[0014] Preferably, the cylinder body houses a thyristor that communicates with the MCU. The thyristor is electrically connected to the main control board, located to the side of the MCU, and detachably fixed to the outer wall of the inner cylinder. A second heat-dissipating aluminum fin is attached to the thyristor. The inner cylinder has a second through-hole matching the second heat-dissipating aluminum fin, and the second heat-dissipating aluminum fin is detachably connected to the second through-hole. The second through-hole is located between the motor and the heating element. The thyristor is located inside the cylinder body but outside the inner cylinder, and it contacts the cool air blown out by the motor through the second heat-dissipating aluminum fin, facilitating heat dissipation from the thyristor.

[0015] Preferably, the motor is covered with a shock-absorbing sleeve, and the motor is connected to the inner wall of the inner cylinder through the shock-absorbing sleeve. The shock-absorbing sleeve on the outside of the motor reduces vibration and noise during operation.

[0016] Preferably, an air inlet hood is provided at the air inlet end. The air inlet hood is detachably connected to and locked in place with the cylinder body. A filter screen is provided inside the air inlet hood, and the edges of the filter screen are fixed with soft rubber. The filter screen is sealed to the air inlet hood through the soft rubber. The soft rubber on the outside of the filter screen facilitates the sealing between the filter screen and the air inlet hood and allows for easy removal and cleaning of the filter screen.

[0017] Preferably, the buttons include a temperature control button for adjusting the air temperature, a power button, and an AI smart button for controlling the on / off state of the intelligent sensing module. The power button controls the entire hair dryer to turn on and off; the temperature control button is made of transparent material to adjust the air temperature, and the color change with the air temperature can be clearly observed from the light-transmitting area of ​​the temperature control button; the AI ​​smart button turns the intelligent sensing module on and off.

A shock-absorbing sleeve is installed on the outside of the motor to reduce vibration and noise during motor operation; 8. The filter screen is covered with soft rubber on the outside, which facilitates the sealing between the filter screen and the air inlet cover, and makes it easy to remove and wash the filter screen.
