Description

A hair dryer with a power-off anti-scalding indicator. Technical Field

[0001] This utility model relates to the technical field of hair dryers, and in particular to a hair dryer with a power-off anti-scalding reminder function. Background Technology

[0002] Currently, most hair dryers on the market cause burns when the power is switched off abruptly or suddenly cut off while the hot air setting is on. To heat the air being blown out, the heating element is typically mounted on the inner wall of the hair dryer near the air outlet. While heating the air, the heating element also transfers heat to the inner wall of the air outlet, causing the temperature near the outlet to rise. During the drying process, because the hot airflow is continuously blowing out, users usually do not directly touch the air outlet, thus avoiding the risk of burns.

[0003] However, when a hair dryer is suddenly turned off or the power is cut off, the fan motor inside immediately stops rotating, and no more airflow comes out of the vent. At this time, the heating element still has a lot of residual heat that cannot be dissipated in time, which may even aggravate the high temperature buildup at the vent. Since there is no airflow, users are likely to come into contact with the vent when placing, storing, or moving the hair dryer, which may result in burns.

[0004] To address this issue, some solutions have been attempted in existing technologies, such as:

[0005] One solution uses a temperature control element: a temperature sensor is installed inside the hair dryer, which automatically cuts off the power when the temperature gets too high to prevent overheating. However, this solution cannot solve the problem of residual heat after power is cut off.

[0006] Using heat insulation materials: Heat insulation materials are used around the air outlet to reduce surface temperature. However, the heat insulation effect of these materials is limited, and they also increase the size and cost of the hair dryer.

[0007] Warning stickers: High-temperature warning stickers are placed on hair dryers to remind users of the risk of high temperatures. However, this method of warning is not intuitive and is easily overlooked by users.

[0008] Therefore, existing technologies still have shortcomings and cannot effectively solve the problem of burns caused by residual heat from the air outlet after a hair dryer is powered off. Summary of the Invention

[0009] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0010] This utility model provides a hair dryer with a power-off anti-scalding warning function, including a hair dryer body and a fan component and a heating component installed on the body. The fan component is installed inside the body and drives air to enter from the air inlet of the body. The air is accelerated in the airflow channel inside the body to form a high-speed airflow that is blown out from the air outlet. The heating component is installed in the airflow channel inside the body and heats the high-speed airflow so that the air outlet blows out high-temperature air with a certain temperature. It also includes a power supply component and an indicator component that are electrically connected to each other. The power supply component provides operating power to the indicator component, and the indicator component issues an anti-scalding warning message.

[0011] Furthermore, the power supply component is set as a supercapacitor.

[0012] Furthermore: the identification components are set with LED beads.

[0013] Furthermore, the marking component is set with multiple LED beads, and the multiple LED beads are evenly spaced and installed on the outer wall of the hair dryer body.

[0014] Furthermore, the marking component is set as a light ring composed of LED beads, which is installed on the side wall of the hair dryer body in the circumferential direction.

[0015] Furthermore, the marking component is set as a light strip composed of LED beads, which is installed on the side wall of the blower body along the axial direction.

[0016] Furthermore, it also includes a temperature sensor, which is electrically connected to the power supply component and configured to allow the identification component to issue a scalding warning message based on the temperature value detected by the temperature sensor.

[0017] Furthermore, the LED beads of the marking component are configured in a blinking mode with an intermittent switch, and the interval time of the intermittent switch is adjusted according to the temperature value detected by the temperature sensor.

[0018] Furthermore, the LED beads of the marking component are configured to a continuously lit mode with gradually decreasing brightness, and their brightness is adjusted according to the temperature value detected by the temperature sensor or according to the remaining power of the power supply component.

[0019] Furthermore: the power supply component is set as an energy storage battery, and the labeling component is set as an electronic screen. The energy storage battery provides operating power to the electronic screen, enabling the electronic screen to issue a heat protection warning.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. Prevent burns: The anti-scalding warning prevents users from coming into contact with high-temperature parts when handling the hair dryer, thus preventing the risk of burns and improving safety.

[0022] 2. Independent power supply, still effective even when power is off: It uses an independent power supply component, so even if the hair dryer is powered off, the indicator component can still work normally, ensuring the reliability of the anti-scalding warning.

[0023] 3. Diverse prompting methods: The signage components can take various forms, such as LED beads, light rings, and light strips, and can adopt flashing or constant-on modes to meet the needs of different users.

[0024] 4. Enhanced alerts: The flashing frequency or brightness of the LED beads can be adjusted based on the temperature value detected by the temperature sensor or the remaining power of the power supply components, thereby achieving a more intuitive and effective anti-scalding alert.

[0025] 5. Simple structure and low cost: This anti-scalding reminder device has a simple structure, is easy to implement, and has a low cost, making it a promising candidate for market application.

[0026] 6. Improve user experience: This solution can significantly improve the user experience and enhance user trust and satisfaction with the product.

[0027] With the above improvements, this utility model provides a safe, reliable, effective, simple, and low-cost anti-scalding solution for hair dryers when the power is off. It has significant beneficial effects, can effectively solve the problems existing in the prior art, and has high practical value and market competitiveness.

[0038] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] Please refer to Figures 1 to 6. In this embodiment of the present invention, a hair dryer with a power-off anti-scalding reminder function includes a hair dryer body 10 and a fan component 50 and a heating component 60 installed on the body 10. The fan component 50 is installed inside the body 10 and drives air to enter from the air inlet 11 of the body 10. The air is accelerated in the airflow channel 13 inside the body 10 to form a high-speed airflow that is blown out from the air outlet 12. The heating component 60 is installed in the airflow channel 13 inside the body 10 and heats the high-speed airflow so that the air outlet 12 blows out high-temperature air with a certain temperature. It also includes a power supply component 30 and an indicator component 21 that are electrically connected to each other. The power supply component 30 provides operating power to the indicator component 21, and the indicator component 21 issues an anti-scalding reminder message.

[0040] Specifically, a common problem with current hair dryers on the market is the high temperature and potential burns at the air outlet 12 when the hair dryer is turned off or suddenly powered off during hot air operation. To heat the blown air, the heating element 60 is typically installed on the inner wall of the body 10 attached to the air outlet 12. While heating the air, heat is also transferred to the inner wall of the body 10, causing its temperature to rise. During operation, the continuous flow of hot air prevents direct contact with the air outlet 12, thus avoiding burns. However, when the hair dryer is suddenly turned off or powered off, the motor stops immediately, and no more airflow comes out of the air outlet 12. The heating element inside remains hot and cannot dissipate quickly enough, potentially exacerbating the heat buildup at the air outlet 12. Without airflow, users are more likely to come into contact with the air outlet 12 when placing, storing, or moving the hair dryer, posing a risk of burns.

[0041] Therefore, through research and development, this utility model has improved by setting a power supply component 30 and an indicator component 21 on the hair dryer body 10. The power supply component 30 is used to provide independent power, so even if the hair dryer is turned off or the power is cut off, it can still provide operating power to the indicator component 21, so that the indicator component 21 can issue anti-scalding warning information to warn the user and prevent the user from coming into contact with high-temperature parts when handling the hair dryer body 10, thereby preventing the risk of burns.

[0042] Secondly, since the power supply component 30 of the hair dryer has relatively little power after the power is cut off, to reduce energy consumption, it is preferable to only set up LED beads 22 for alarm. For example, a certain number of LED beads 22 can be set in the externally observable parts of the hair dryer body 10, so that the power supply component 30 directly drives the LED beads 22 after the hair dryer is cut off, causing them to emit alarm lights. For example, the LED beads 22 can be set as red alarm lights, and the illumination time of the LED beads 22 can be controlled by delay, so that after illuminating for a certain period of time to indicate high temperature, they will automatically turn off. For example, the LED beads 22 are preferably set as red alarm lights, and turn off after a 3-minute delay. After the high-temperature component has cooled down naturally for 3 minutes, its temperature will have dropped significantly, and there will be no risk of burns to the human body.

[0043] In addition, because the power supply component 30 has relatively little power and only supports the LED beads 22 to light up for a short time, a specific delay time can be omitted, allowing the LED beads 22 to remain lit until the power supply component 30 has exhausted its stored power.

[0044] As shown in Figure 1, preferably, the power supply component 30 is a farad capacitor.

[0045] Specifically, farad capacitors are characterized by fast charging speed, long cycle life, high energy conversion efficiency, and suitability for long-term discharge with low current. Therefore, farad capacitors can be used as power supply components 30 to power the marking component 21. Utilizing the rapid charging, discharging, and energy storage characteristics of farad capacitors, when the external power supply of the hair dryer is normal, the farad capacitor is in a charging and energy storage state. When the external power supply of the hair dryer is interrupted, the farad capacitor supplies power to the marking component 21, causing it to emit the set anti-scalding indicator light.

[0046] As shown in Figures 1 to 4, preferably, the marking component 21 is installed on the outer ring of the side wall of the hair dryer body 10 near the air outlet 12.

[0047] Specifically, since the part of the hair dryer body 10 that has residual heat is mainly the air outlet 12, the marking component 21 can be directly set on the outer side wall near the air outlet, so that it can more intuitively remind the user to avoid burns.

[0048] As shown in Figure 3, preferably, the marking component 21 is installed at the end of the hair dryer body 10 where the air outlet 12 is located, or at the end of the hair dryer body 10 where the circuit board is located. Since the high temperature is mainly concentrated at the end of the air outlet 12, in order to provide users with a direct anti-scalding reminder, the LED light bead 22 can be directly set at the end of the air outlet 12.

[0049] As shown in Figure 6, preferably, in another embodiment, for ease of installation, the LED beads 22 can also be mounted on an existing circuit board, such as the circuit board at the tail of a hair dryer, thereby simplifying the structure, improving production efficiency, and reducing production costs. Since the circuit board is usually installed inside the housing, in order to ensure that the light emitted by the LED beads 22 can be observed from the outside, it is preferable to make the housing corresponding to the circuit board part of the housing as a light-transmitting material, such as transparent acrylic or translucent plastic.

[0050] As shown in Figures 1 and 3, preferably, the marking component 21 is configured as an LED light bead 22.

[0051] Specifically, since the anti-scalding reminder function is mainly activated when the hair dryer body 10 is turned off or disconnected from power, and the power supply component 30 can only provide limited power, the indicator component 21 is preferably set as an LED light bead 22 with relatively low power consumption.

[0052] As shown in Figures 1 and 3, preferably, the marking component 21 is configured as a plurality of LED beads 22, and the plurality of LED beads 22 are evenly spaced and installed on the outer wall of the hair dryer body 10.

[0053] Specifically, to provide anti-scalding warnings to users from multiple angles, multiple LED beads 22 can be installed at even intervals on the outer wall of the hair dryer body 10 around its circumference. For example, four LED beads 22 can be installed at 90-degree intervals around the circumference of the hair dryer body 10, forming a structure that provides anti-scalding warnings from all four directions. In addition to this spaced installation method, to further enhance the warning effect and aesthetics, the indicator component 21 can also be set as a light ring 23 or a light strip 24.

[0054] As shown in Figure 2, preferably, the marking component 21 is set as a light ring 23 composed of LED beads 22, and the light ring 23 is installed on the circumferential side wall of the hair dryer body 10.

[0055] Specifically, in order to further enhance the warning effect and increase the aesthetics, the marking component 21 can preferably be set as a light ring 23, that is, multiple LED beads 22 are installed on the side wall of the hair dryer body 10 along its circumference to form an overall warning light ring 23.

[0056] As shown in Figure 4, preferably, the marking component 21 is set as a light strip 24 composed of LED beads 22, and the light strip 24 is installed on the side wall of the blower body 10 in the axial direction.

[0057] Specifically, to enrich the prompting effect of the indicator component 21, it can also be set as a long strip of light 24. That is, a certain number of LED beads 22 are installed on the side wall of the hair dryer body 10 along its axial direction to form a light strip 24 of a certain length. Moreover, multiple light strips 24 can be set and arranged along the axial direction of the hair dryer body 10 at certain intervals to form another beautiful prompting combination.

[0058] Secondly, one or two LED beads 22 can be set on both sides of the light strip 24 near the air outlet 12, so that the light strip 24 forms an arrow shape and the tip of the arrow points to the air outlet 12, further enhancing the anti-scalding reminder effect.

[0059] As shown in Figures 2 and 4, preferably, it also includes a temperature sensor 40, which is electrically connected to the power supply component 30 and configured to allow the identification component 21 to issue a scalding warning message based on the temperature value detected by the temperature sensor 40.

[0060] The LED beads 22 of the marking component 21 are set to a blinking mode with an intermittent switch, and the interval time of the intermittent switch is adjusted according to the temperature value detected by the temperature sensor 40.

[0061] Specifically, since the operating power provided by the power supply component 30 is limited, it is preferable to set the LED beads 22 to switch on and off at regular intervals, causing the emitted light to flash. The specific switching interval can be adjusted according to temperature; for example, the higher the temperature, the shorter the interval between light-emitting cycles and the faster the flashing frequency. Conversely, as the temperature naturally decreases, the interval between light-emitting cycles of the LED beads 22 becomes longer, and the flashing frequency slows down. This setting not only provides a clear indication of temperature to the user through the flashing frequency—higher temperature, faster flashing, aligning with common sense—but also conforms to the natural law of gradually decreasing internal power in the power supply component 30: faster flashing consumes more power, and slower flashing consumes less power.

[0062] Preferably, the LED beads 22 of the marking component 21 are set to a constant-on mode with gradually decreasing brightness. The brightness is adjusted according to the temperature value detected by the temperature sensor 40 or according to the remaining power of the power supply component 30.

[0063] Specifically, in another embodiment, the LED beads 22 can be set to a constantly lit mode with gradually decreasing brightness. The change in brightness serves as a temperature indicator for the user; that is, the lower the temperature, the lower the brightness. The specific curve of brightness reduction can be adjusted based on the temperature value detected by the temperature sensor 40. For example, a microcontroller unit can be installed inside the hair dryer body 10 to intelligently control all electronic components. The microcontroller unit can receive the temperature value detected by the temperature sensor 40 and then control the brightness of the LED beads 22 according to existing control algorithms, so that the brightness reduction curve matches the temperature reduction curve; that is, the higher the temperature, the higher the brightness, and the stronger the warning effect.

[0064] Secondly, since the microcontroller also consumes power, it is not suitable for applications where the power supply component 30 has limited power, such as when the power supply component 30 is a supercapacitor. Therefore, the brightness adjustment mode of the LED bead 22 can be set to adjust based on the remaining power of the power supply component 30. That is, without the intervention of the temperature sensor 40 and the microcontroller, the LED bead 22 is directly connected to the power supply component 30. When the external power supply of the hair dryer is connected, the power supply component 30 charges, and the LED bead 22 illuminates at full power, entering the brightest mode. When the external power supply is disconnected, the power supply component 30 directly supplies power to the LED bead 22, allowing it to continue illuminating. However, since the storage capacity of the supercapacitor is small, the voltage decreases synchronously with the decrease in power, and the brightness of the LED bead 22 also decreases accordingly. This setting also conforms to the characteristic that the temperature of the air outlet 12 gradually decreases after natural dissipation, thus providing a scalding warning to the user.

[0065] As shown in Figures 1 and 5, preferably, the power supply component 30 is configured as an energy storage battery, and the marking component 21 is configured as an electronic screen 25. The energy storage battery provides operating power to the electronic screen 25, enabling the electronic screen 25 to issue an anti-scalding warning.

[0066] Specifically, under another feasible design approach, this utility model designs different configurations for the power supply component 30 and the labeling component 21. The power supply component 30 can also be set as an energy storage battery, such as a rechargeable lithium battery, a rechargeable nickel-metal hydride battery, or a rechargeable button battery, providing a relatively large energy reserve, thereby driving the electronic screen 25 to operate and display preset prompt information. For example, the electronic screen 25 can directly display the words "Caution: Burns" or flash a prompt, both of which can provide burn prevention warnings to the user.

[0067] Secondly, since the energy storage battery has relatively sufficient power, it can also drive the microcontroller and temperature sensor 40 to operate accordingly, thereby obtaining the current temperature of the heating element 60. This current temperature can be directly displayed on the electronic screen 25 for intuitive temperature indication. Simultaneously, after the temperature of the heating element 60 has naturally dissipated for a certain period and is relatively low enough to eliminate the risk of burns, the electronic screen 25 or LED beads 22 can be turned off, disabling the anti-scalding warning function. For example, the function can be turned off when the temperature drops to 36 degrees Celsius. Alternatively, a delayed shutdown module can be set in the microcontroller to delay the shutdown of the LED beads 22 or electronic screen 25. For example, after 1-3 minutes, when the temperature of the heating element 60 has also dropped to a certain level where there is no risk of burns, the function can be turned off.

[0068] Therefore, this utility model provides a function for a hair dryer that can continue to emit light to provide a burn warning after power failure, so that the hair dryer still has a very obvious light effect or luminous icon to remind the user to be careful of burns after power failure, which has a positive practical effect.

[0069] Example 1: Anti-scalding hair dryer based on supercapacitor and LED red alarm light

[0070] Structural composition

[0071] The blower body 10 contains a fan component 50 and a heating element 60. The fan component 50 drives air to enter through the air inlet 11, accelerates it in the airflow channel 13 inside the body 10, and then blows it out through the air outlet 12. The heating element 60 is located in the airflow channel 13 and heats the high-speed airflow, causing high-temperature air to be blown out of the air outlet 12.

[0072] It also includes a power supply component 30 and an indicator component 21. The power supply component 30 is a supercapacitor, and the indicator component 21 is a red alarm light composed of one or more LED beads 22, mounted on a circuit board at the tail of the hair dryer. The supercapacitor and the LED beads 22 are electrically connected to each other through the circuit board.

[0073] Working principle

[0074] When the hair dryer is powered by an external power source, the supercapacitor is in a charging and energy storage state. At this time, the fan component 50 and the heating component 60 are working normally, and the hair dryer blows out hot air.

[0075] If the hair dryer is suddenly turned off or loses power, and the external power supply stops, the supercapacitor immediately starts supplying power to the indicator component 21, causing the LED red alarm light to illuminate and emit red light to provide a burn warning. In order to save energy, preferably, the LED beads 22 are set to a flashing mode with intermittent switching. Through this flashing mode, the user is visually alerted to the high temperature of the hot part, warning the user to avoid contact and burns.

[0076] Example 2: Anti-scalding hair dryer using a supercapacitor, temperature sensor 40, and LED light strip 24

[0077] Structural composition

[0078] It also has a conventional hair dryer body 10, with a fan component 50 and a heating component 60 inside to realize the functions of blowing and heating.

[0079] A temperature sensor 40 can also be added, while the power supply component 30 remains a supercapacitor. The marking component 21 is a long strip light bar 24, composed of multiple LED beads 22 mounted along the axial upward side wall of the blower body 10. At one end of the light bar 24 near the air outlet 12, an LED bead 22 is set on each side, making the light bar 24 form an arrow shape, with the arrow tip pointing towards the air outlet 12. The temperature sensor 40 is installed at a position that can accurately detect the temperature of the heating element 60 or the air outlet 12, and is electrically connected to the supercapacitor and the LED light bar 24.

[0080] Working principle

[0081] Under normal power supply conditions, the supercapacitor charges. The hair dryer operates, the fan generates airflow, and the heating element 60 heats the airflow.

[0082] In the event of a power outage or shutdown, the supercapacitor supplies power to the temperature sensor 40 and the LED strip 24. The temperature sensor 40 continuously monitors the temperature of the heat-generating component 60 or the air outlet 12, and transmits the detected temperature data to the control circuit of the LED bead 22. The control circuit adjusts the flashing frequency of the LED bead 22 according to the temperature. If the temperature is high, the flashing frequency of the LED bead 22 increases to alert the user to the high temperature; if the temperature is low, the flashing frequency of the LED bead 22 decreases.

[0083] Additionally, it may include a microcontroller unit (MCU): used to receive the temperature value detected by the temperature sensor 40 and control the brightness of the LED beads 22 according to the control algorithm, so that the brightness reduction curve matches the temperature reduction curve.

[0084] In addition, the LED strip 24 is set to a continuously lit mode with gradually decreasing brightness. When the external power supply to the hair dryer is connected, the supercapacitor charges, and the LED strip 24 illuminates at full power, reaching its brightest state. After the external power supply is disconnected, the supercapacitor supplies power, and as the power decreases, the voltage drops, and the brightness of the LED strip 24 gradually decreases. This brightness change matches the natural temperature decrease of the air outlet 12, allowing users to intuitively understand the temperature of the air outlet 12 through the brightness of the LED strip 24, serving as a scalding warning. When the LED strip 24 is brighter, it warns the user of high temperature; when the LED strip 24 is dimmer, it indicates that the temperature is gradually decreasing. The arrow points to the air outlet 12, further enhancing the scalding warning effect.

[0085] Example 3: Anti-scalding hair dryer based on energy storage battery and electronic screen 25

[0086] Structural composition

[0087] The hair dryer body 10 includes a fan component 50 and a heating component 60, realizing basic blowing and heating functions.

[0088] The power supply component 30 is an energy storage battery, such as a rechargeable lithium battery. The identification component 21 is an electronic display 25, installed in a location easily visible to the user on the hair dryer body 10. The temperature sensor 40 is used to detect the temperature of the heating element 60 and is electrically connected to the energy storage battery, the electronic display 25, and the microcontroller unit. The microcontroller unit can intelligently control the electronic components of the entire notification system.

[0089] Working principle

[0090] During normal operation, the energy storage battery is charged, and the blower's fan and heating element 60 operate normally.

[0091] When the hair dryer is powered off or turned off, the energy storage battery powers the electronic display 25, temperature sensor 40, and microcontroller unit. The temperature sensor 40 transmits the detected current temperature data of the heating element 60 to the microcontroller unit.

[0092] The electronic screen 25 operates according to the instructions of the microcontroller unit. It can directly display the words "Caution: Burns" or flash a warning. Simultaneously, the electronic screen 25 can also display the current temperature of the heating element 60, providing the user with intuitive temperature information. When the temperature of the heating element 60 naturally decreases to a certain level, such as 36 degrees Celsius, the microcontroller unit controls the electronic screen 25 to turn off, discontinuing the burn warning function. Alternatively, the delay-off module within the microcontroller unit can automatically turn off the electronic screen 25 after 1-3 minutes of warning, determining that the temperature of the heating element 60 has decreased to a safe range, thus ensuring safety and avoiding unnecessary energy consumption.

[0093] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
