Description

Technical Field

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

[0002] Currently, most hair dryer heating elements on the market use a single heating element design. This design is relatively simple to manufacture and the cost is relatively controllable, so it is widely used in hair dryer products. However, this type of heating element has a significant drawback in terms of voltage adaptability. Most hair dryer heating elements are designed to operate on a single voltage, meaning they can only function normally at specific voltage values ​​(such as 220V or 110V).

[0003] With the improvement of people's living standards and the booming development of tourism, users are traveling to other countries more and more frequently. Different countries have different electricity standards and voltage values. For example, some countries use a 220V voltage standard, while others use 110V. When users bring hair dryers designed for single voltage to countries with different voltage standards, voltage incompatibility problems will occur.

[0004] Because the heating element can only adapt to a single voltage, the hair dryer will not function properly when connected to a power source that does not meet the product's voltage requirements. Specifically, the heating element may fail to generate enough heat, resulting in poor drying performance and ineffective hair drying; or the heat generated by the heating element may be unstable, affecting the user experience. More seriously, this voltage mismatch can also cause overload in the hair dryer's internal circuitry, leading to overheating and damaging internal electronic components and the heating element. This not only damages the product but may also pose safety hazards, such as causing a fire.

[0005] Therefore, the existing single-voltage hair dryer heating pad design is significantly inadequate in meeting the needs of users traveling across borders. There is an urgent need for a hair dryer heating pad technology that can adapt to multiple voltages to improve the versatility and safety of hair dryer products. Utility Model Content

[0009] In one specific embodiment, the middle section of the mica support is provided with an isolation protrusion, which is used to separate the first heating wire and the second heating wire.

[0016] In one specific embodiment, the mica support is formed by combining two mica sheets at a 90-degree angle or three mica sheets at a 60-degree angle.

[0018] Secondly, this utility model embodiment provides a hair dryer, including the hair dryer heating frame structure as described above.

[0019] The advantages of this utility model hair dryer compared to existing technologies are as follows: By setting a heating frame structure in the hair dryer, and then setting a first heating wire with a working voltage range of 100-125V and a second heating wire with a working voltage range of 200-245V on the mica bracket, when users use it in countries with different voltage standards, they can select the appropriate heating wire according to the local voltage.

[0031] See Figures 1 to 2 The specific embodiment shown in this utility model discloses a hair dryer heating frame structure, including: a mica support 10, a first heating wire 20 and a second heating wire 30. The first heating wire 20 and the second heating wire 30 are respectively connected to the upper and lower ends of the mica support 10. The working voltage range of the first heating wire 20 is 100-125V, and the working voltage range of the second heating wire 30 is 200-245V.

[0032] Specifically, by separately installing a first heating wire 20 with a working voltage range of 100-125V and a second heating wire 30 with a working voltage range of 200-245V on the mica bracket 10, users can select the appropriate heating wire according to the local voltage when using the product in countries with different voltage standards. This ensures that the hair dryer can work stably in countries with voltage ranges of 100-125V and 200-245V, greatly improving the product's practicality and market competitiveness. Furthermore, single-voltage hair dryers are prone to overheating or failure to heat properly due to excessive or insufficient current when the voltage is mismatched, potentially leading to damage to electronic components or even a fire risk. This invention, through its dual-voltage heating wire design, ensures that the product always operates within its rated voltage range. For example, at 110V, only the first heating element 20 (100-125V) operates, preventing the second heating element 30 (200-245V) from overloading due to low voltage; at 220V, only the second heating element 30 operates, preventing the first heating element 20 from burning out due to high voltage. This precise adaptation mechanism effectively reduces the product failure rate, extends the lifespan of the heating element and the entire hair dryer, and significantly improves user safety.

[0033] More specifically, a voltage sensor is integrated inside the hair dryer to monitor the input voltage in real time. When the voltage is between 100-125V, the circuit of the first heating wire 20 is automatically closed, and the circuit of the second heating wire 30 is opened; when the voltage is between 200-245V, the circuit of the second heating wire 30 is closed, and the circuit of the first heating wire 20 is opened. Users can also manually select the heating element (e.g., activating only the first heating wire 20 or the second heating wire 30) according to their needs via a physical switch or smart touch button, enhancing the personalized experience.

[0034] In one embodiment, the mica support 10 has an isolation protrusion 11 in the middle section, which is used to separate the first heating wire 20 and the second heating wire 30.

[0035] Specifically, the first heating wire 20 and the second heating wire 30 are wound around the upper and lower ends of the mica support 10, respectively. An isolation protrusion 11 is located in the middle section of the mica support 10, precisely separating the winding areas of the first heating wire 20 and the second heating wire 30, ensuring no electrical connection between the two heating wires. Furthermore, heating wires operating at different voltage levels may generate electromagnetic interference during operation. The isolation protrusion 11 reduces electromagnetic coupling between the two heating wires, minimizing the impact of electromagnetic interference on other electronic components of the hair dryer, and improving the stability and reliability of the equipment. In addition, the isolation protrusion 11 provides independent working spaces for the two heating wires, allowing each heating wire to heat up normally according to design requirements. The first heating wire 20 operates in a low-voltage environment, while the second heating wire 30 operates in a high-voltage environment, without interference, thereby improving heating efficiency.

[0036] In one embodiment, the mica support 10 is also connected to a current fuse 40.

[0037] Specifically, based on the hair dryer's operating parameters, such as rated voltage and rated power, calculate the normal operating current and, considering a certain safety margin, select a suitable current fuse 40. For example, if the hair dryer's rated power is 1500W and rated voltage is 220V, the normal operating current is approximately 6.8A, so a current fuse 40 with a rated current of 8A or 10A can be selected. Simultaneously, the fuse's fusing characteristics should be considered, selecting a fuse that can quickly melt when the current exceeds a certain multiple of the rated value to ensure timely circuit disconnection in case of overload or short circuit. Place the selected current fuse 40 into the mounting structure of the mica bracket 10 according to the design requirements. If it is a slot-type installation, gently place the fuse into the slot, ensuring a tight fit; if other installation methods are used, follow the corresponding operating steps. After installation, reliably connect both ends of the current fuse 40 to the connection terminals on the mica bracket 10. Connection methods can include welding, crimping, or plugging, ensuring a firm connection and low contact resistance.

[0038] In other words, when the hair dryer malfunctions, such as a short circuit in the heating element or a stuck fan causing excessive current, the fuse 40 will quickly melt, cutting off the circuit and stopping the heating element from working. This prevents the heating element from overheating due to prolonged overload, which could lead to melting, insulation damage, and other problems, thus extending the lifespan of the heating element. Furthermore, excessive current may cause overheating and electromagnetic forces in the hair dryer's internal electrical components, creating mechanical stress on the heating element. The timely melting of the fuse 40 eliminates this mechanical stress, protecting the structural integrity of the heating element and preventing deformation or damage.

[0039] In one embodiment, the mica support 10 has an opening area, and the current fuse 40 is disposed in the opening area.

[0040] Specifically, by creating an opening on the mica bracket 10 to mount the current fuse 40, the need for separate additional mounting space for the current fuse 40 is avoided, thereby reducing the overall size of the heating element. This is particularly important for the design of miniaturized, portable hair dryers, enabling the product to meet functional requirements while being more compact and lightweight, making it easier to carry and use. Furthermore, the opening allows for a more compact arrangement of the current fuse 40, the mica bracket 10, and the heating wire, improving space utilization. At the same time, this rational layout also reduces interference between components, improving product performance and reliability.

[0041] In one embodiment, the mica support 10 is also connected to a temperature modulator 50.

[0042] Specifically, select a suitable temperature modulator 50 based on the hair dryer's operating temperature range and protection requirements. The operating temperature of the temperature modulator 50 should be set to 105℃, while also considering its accuracy and reliability. Furthermore, the rated current and voltage of the temperature modulator 50 should match the hair dryer's circuit parameters to ensure normal operation. For example, select a temperature modulator 50 with an operating temperature of 105℃±3℃, a rated current of 10A, and a rated voltage of 250V.

[0043] In other words, when the temperature of the heating element exceeds 105℃, the temperature modulator 50 automatically disconnects the circuit, cutting off the power supply to the heating element to prevent the heating wire from melting due to overheating and the insulation layer from being damaged. It also prevents other circuit components from aging and being damaged due to high temperatures, thus protecting the safety of the entire circuit system. When the temperature drops, the temperature modulator 50 automatically reconnects the circuit, allowing the heating element to return to normal operation. This automatic recovery function avoids product damage caused by untimely manual intervention or improper operation, improving product reliability and stability. Furthermore, because the temperature modulator 50 can respond promptly to over-temperature conditions and automatically recover, it reduces equipment downtime caused by over-temperature protection, improving product efficiency.

[0044] In one embodiment, the mica support 10 is also connected to a positive ion emitting brush 60.

[0045] Specifically, to ensure a reliable connection between the positive ion emitting brush 60 and the mica support 10, various connection methods can be used. Common methods include snap-fit ​​connection, screw fixing, or adhesive bonding. If a snap-fit ​​connection is used, mutually cooperating snap-fit ​​structures are designed on both the mica support 10 and the positive ion emitting brush 60, and the connection is achieved through the snap-fit. If screw fixing is used, screw holes are pre-drilled on the mica support 10, and threaded holes are designed at corresponding positions on the mounting base of the positive ion emitting brush 60, and screws are used to fix it. If adhesive bonding is used, an adhesive with good high-temperature resistance should be selected to attach the positive ion emitting brush 60 to the mica support 10.

[0046] In other words, positive ions can neutralize the negative charge on hair, effectively reducing frizz and tangles caused by static electricity. Hair is prone to static electricity in dry winters or when wearing synthetic fabrics. Using a hair dryer with a positive ion emission brush 60 can make hair smoother and easier to comb. Furthermore, because the positive ion emission brush 60 reduces static electricity and frizz, users will feel more comfortable during the blow-drying process, and hair will not stick to their face or clothing due to static electricity.

[0047] In one embodiment, the mica support 10 is also connected to a negative ion emitting brush 70 in a region offset from the positive ion emitting brush 60.

[0048] Specifically, the mica support 10 is divided into a positive ion emission area and a negative ion emission area, and these two areas are staggered to avoid the positive ion emission brush 60 and the negative ion emission brush 70 being too close in space. For example, the positive ion emission brush 60 can be installed on one edge of the mica support 10, while the negative ion emission brush 70 can be installed on the opposite side of the mica support 10, leaving a certain gap in between to ensure that the two do not interfere with each other when working.

[0049] In other words, by staggering the positive ion emitting brush 60 and the negative ion emitting brush 70, interference between them during operation is avoided, allowing for purer emission of both positive and negative ions. This allows users to simultaneously enjoy the different hair care effects of positive and negative ions while using the hair dryer; for example, positive ions reduce static electricity and nourish hair, while negative ions repair damaged hair and increase shine. Furthermore, because the positive and negative ion emitting brushes 60 and 70 do not interfere with each other, they can independently emit ions with maximum efficiency, thereby increasing the overall ion concentration emitted by the hair dryer. This higher ion concentration allows for better coverage of the hair, providing more comprehensive care. Additionally, the simultaneous action of positive and negative ions improves hair health, making it smoother, shinier, and more elastic. Users of hair dryers with this design will noticeably experience improved hair quality, such as easier combing and longer-lasting styling.

[0050] In one embodiment, the mica support 10 is further provided with a clamping seat 12 corresponding to the positive ion emitting brush 60 and the negative ion emitting brush 70.

[0051] Specifically, clamping seats 12 are provided at both the upper and lower ends of the mica support 10, which simultaneously clamp the launching brush at the upper and lower ends to ensure that the launching brush is firmly installed on the mica support 10 and will not shake or fall off during operation.

[0052] In other words, clamping the positive ion emitting brush 60 and the negative ion emitting brush 70 at both ends provides sufficient clamping force, effectively preventing the emitting brushes from loosening or falling off due to vibration, airflow impact, or other reasons during operation. This ensures the stability and reliability of the positive and negative ion emitting functions of the hair dryer during long-term use.

[0053] In one embodiment, the mica support 10 is formed by combining two mica sheets at a 90-degree angle or three mica sheets at a 60-degree angle.

[0054] Specifically, combining two mica sheets at a 90-degree angle or three mica sheets at a 60-degree angle makes full use of the limited internal space of the hair dryer. Compared to the traditional flat mica support 10, this combined structure allows for layout in three-dimensional space, enabling components such as the positive ion emitting brush 60 and the negative ion emitting brush 70 to be installed more compactly, reducing the size of the hair dryer. Furthermore, by combining mica sheets at different angles, the interior of the hair dryer can be divided into different functional areas, such as a positive ion emitting area, a negative ion emitting area, and a circuit control area. This facilitates the rational layout and coordination of components, improving the overall performance of the hair dryer. In addition, the support structure formed by combining multiple mica sheets has higher strength and rigidity. The angled design between the mica sheets increases the structural stability, enabling it to withstand greater external forces and vibrations. During the operation of the hair dryer, even under the impact and vibration of airflow, the structural integrity can be maintained, ensuring the normal operation of components such as the positive ion emitting brush 60 and the negative ion emitting brush 70. Furthermore, a well-designed angle can distribute stress and reduce deformation of the mica sheet under high temperature and stress. While mica sheets themselves have good high-temperature resistance, deformation can still occur after prolonged operation in high-temperature environments. By using a modular structure, the stress on each mica sheet can be reduced, extending its service life.

[0055] This utility model also discloses a hair dryer, including the hair dryer heating frame structure described above.

[0056] Specifically, by incorporating a heating element structure into the hair dryer, and then by installing a first heating wire 20 with a working voltage range of 100-125V and a second heating wire 30 with a working voltage range of 200-245V on the mica bracket 10, users can select the appropriate heating wire based on the local voltage when using the hair dryer in countries with different voltage standards. This ensures that the hair dryer can work stably in countries with voltage ranges of 100-125V and 200-245V, greatly enhancing the product's practicality and market competitiveness.

[0057] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
