Description

Technical Field

[0001] This utility model relates to the field of hair dryer and hair straightener technology, and in particular to a hair dryer and hair straightener with a built-in probe-type temperature controller. Background Technology

[0002] A hair straightener (also known as a hair clipper, flat iron, electric hair clip, etc.) is an electric beauty tool mainly used to heat hair and straighten and smooth it. It achieves the effect of straightening hair by clamping the hair and heating it, which heats up the hair cuticles and makes them smooth. Hair straighteners are commonly used for daily hair styling, especially for those with naturally curly or voluminous hair.

[0003] Hair straighteners typically consist of a handle, temperature control system, heating plate, and clamping plates. When using them, first turn on the straightener, and the internal heating element will quickly heat up to the preset temperature. During the heating process, the straightener monitors the temperature change of the heating plate through 3 to 4 NTC temperature sensors to ensure that the temperature remains stable. Next, the user divides the hair into several small sections, clamps one section of hair with the straightener, and ensures that the clamping plates are parallel and clamp the hair tightly. By sliding the straightener from the roots to the ends of the hair, the heat will open the hair cuticles, thereby changing the shape of the hair and gradually straightening it, ultimately making the hair smooth and straight.

[0004] Although hair straighteners can monitor the temperature changes of the heating plate using 3 to 4 NTC temperature sensors, the traditional 3 to 4 NTC temperature sensors are distributed in different positions on the heating plate. Each temperature sensor has a different measurement range and position, which leads to inconsistent temperature feedback between the temperature sensors. This temperature difference interference can cause some areas to be overheated while other areas are underheated, thus affecting the uniformity of the temperature. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a hair dryer with a built-in probe-type temperature controller, which aims to improve the problem in the existing technology where 3-4 NTC temperature sensors are distributed in different positions on the heating plate, and each temperature sensor has a different measurement range and position, resulting in inconsistent temperature feedback between the temperature sensors.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A hair dryer with a built-in probe-type temperature controller includes a handle, a lower clamp plate installed on the lower outer side of the handle, an upper clamp plate installed on the upper outer side of the handle, a heating plate fixedly connected to the exterior of both the upper and lower clamp plates, a heating wire installed inside both the upper and lower clamp plates, and a temperature control component provided inside both the upper and lower clamp plates.

[0008] The temperature control component includes a locking block, which is fixedly connected to the inside right side of the upper clamping plate and the lower clamping plate, and a needle-type temperature controller body is disposed inside the locking block.

[0009] Furthermore, both the upper clamping plate and the lower clamping plate have air vents on their exteriors.

[0010] Furthermore, the card block has an internal mounting slot, and the needle-type temperature controller body is inserted into the mounting slot.

[0011] Furthermore, the card block is made of silicone.

[0012] Furthermore, a button is mounted on the outside of the handle.

[0013] Furthermore, air inlets are provided around the outer perimeter of the handle.

[0014] Furthermore, a power cord is fixedly connected to the outside of the handle.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, when installing the needle-type thermostat body, it is snapped into the mounting groove inside the clip. The silicone clip has the characteristics of softness and high temperature resistance, which can ensure that the thermostat and the clip fit tightly, improve stability, prevent loosening or displacement, and withstand high temperature without deformation or damage, thereby ensuring the stable operation of the thermostat. Compared with the traditional method of using multiple NTC temperature sensors, the probe-type thermostat can monitor the core temperature of the heating plate or heating element in real time, avoid temperature difference interference, provide stable and uniform temperature feedback, and ensure that the temperature of the heating element is uniform and stable.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-4 This utility model provides an embodiment of a hair straightener with a built-in probe-type temperature controller, including a handle 1 for user convenience. A lower clamping plate 2 is installed on the lower outer side of the handle 1, and an upper clamping plate 3 is installed on the upper outer side of the handle 1. The upper and lower clamping plates 3 and 2 facilitate straightening of the hair. Heating plates 10 are fixedly connected to the exterior of both the upper and lower clamping plates 3 and 2. The function of the heating plates 10 is to ensure that the straightener can heat and straighten the hair evenly and effectively. Heating wires 4 are installed inside both the upper and lower clamping plates 3 and 2. Heating wires 4 are installed inside the upper plate 3 and the lower plate 2 to provide heat by directly heating the plates, so that the hair straightener can straighten the hair quickly and effectively. Temperature control components are installed inside the upper plate 3 and the lower plate 2 to facilitate the monitoring of the temperature of the hair straightener. Air vents 7 are opened on the outside of the upper plate 3 and the lower plate 2. Buttons 8 are installed on the outside of the handle 1 to facilitate the opening and closing of the upper plate 3 and the lower plate 2. Air inlets 12 are opened on all four sides of the outside of the handle 1. A power cord 9 is fixedly connected to the outside of the handle 1 to facilitate the hair straightener to obtain power.

[0025] The temperature control component includes a locking block 5, which is fixedly connected to the inside right side of the upper clamping plate 3 and the lower clamping plate 2. The locking block 5 has a needle-type thermostat body 6 inside, which can monitor the temperature of the hair straightener heating plate or heating element in real time to ensure that the heating temperature is maintained within the preset range. The locking block 5 has an installation slot 11 inside, and the needle-type thermostat body 6 is inserted into the installation slot 11, which improves the installation stability of the needle-type thermostat body 6. The locking block 5 is made of silicone, which has excellent high temperature resistance and can withstand high temperatures during the hair straightener heating process without easily deforming, melting or decomposing.

[0026] Specifically, when installing the needle thermostat body 6, firstly, the needle thermostat body 6 is inserted into the mounting groove 11 inside the clip 5. The clip 5 is made of silicone. The softness and elasticity of silicone ensure a tight fit between the thermostat and the clip 5, allowing the thermostat to be firmly fixed in the predetermined position. This design effectively improves the stability of the thermostat body, preventing the thermostat from loosening or shifting during operation, and ensuring that the thermostat can always accurately monitor the temperature of the heating element. The silicone material has excellent high-temperature resistance, which makes the clip 5 particularly suitable for the high-temperature working environment of hair straighteners. Since hair straighteners generate a lot of heat during use, the thermostat will also be in a high-temperature state during operation. Silicone can withstand prolonged high-temperature environments without deforming, softening, or decomposing due to excessive heat. This provides crucial assurance for the stable operation of the temperature controller. By installing a pin-type temperature controller, the hair straightener overcomes the problem of uneven temperature distribution caused by the traditional method of using 3-4 NTC temperature sensors to monitor different parts of the heating plate. While multiple NTC temperature sensors can monitor temperature changes at different locations on the heating plate, the different measurement ranges and locations of each sensor can easily lead to temperature interference between them. This results in some areas being overheated while others are underheated, affecting the temperature uniformity of the heating plate 10. In contrast, installing a probe-type temperature controller allows for real-time monitoring of the core temperature of the heating plate 10 or heating element. By adjusting the working state of the heating element in real time based on the monitoring results, the temperature difference interference between different temperature sensors is avoided. This monitoring method provides more stable and uniform temperature feedback, ensuring that the temperature of the heating element remains within the set range throughout the entire working process. Through this optimized temperature control method, the hair straightener can achieve a more uniform heat distribution, avoiding the uneven heating problems that may be caused by traditional multi-temperature sensor designs. During use, users can experience a more stable and consistent temperature effect, thereby reducing the risk of damage caused by uneven heating of the hair, making the straightening effect of the hair last longer, and providing better protection. Overall, the application of probe-type temperature controllers greatly improves the temperature control accuracy, working efficiency, and safety of hair straighteners.

[0027] Working principle: When installing the needle-type thermostat body 6, firstly, the needle-type thermostat body 6 is inserted into the mounting slot 11 inside the clip 5. Since the clip 5 is made of silicone, the silicone can ensure a tight fit between the thermostat and the clip 5, thereby improving the stability of the thermostat and preventing it from loosening or shifting during operation. At the same time, the high temperature resistance of silicone makes it very suitable for use in high-temperature environments such as hair straighteners. Even if the thermostat generates high temperatures during monitoring, the silicone material can effectively withstand these temperatures without deformation or damage, thus ensuring the stable operation of the thermostat. This realizes the installation of a probe-type thermostat inside the hair straightener, replacing the traditional method of using 3-4 NTC temperature sensors to maintain temperature uniformity. By installing a probe-type thermostat, the core temperature of the heating plate 10 or heating element can be monitored in real time. It can avoid temperature difference interference between multiple temperature sensors, providing a more stable and uniform temperature feedback, ensuring that the temperature of the heating element remains within the set range, resulting in a more uniform temperature.
