Description

Technical Field

[0001] This application relates to the field of electric heating shears technology, and in particular to an electric heating hair clipper. Background Technology

[0002] From the very beginning of its growth, hair endures multiple stresses: chemical dyes and perms, and alcohol-based conditioning products damage the keratin structure; mechanical friction from brushing, blow-drying, and straightening causes the hair cuticles to lift and crack; and ultraviolet rays and high temperatures hydrolyze and lose the binding substances between the cortex layers. As damage accumulates, the gaps between fibers widen, the ability to retain moisture decreases, the refractive index drops, and hair loses its shine, volume, and elasticity. Hair becomes fragile, sparse, and prone to breakage, and these problems are almost always caused by split ends. Damage usually starts at the ends and spreads upwards. Once split ends occur, the effective cross-sectional area of ​​the fiber decreases, and its mechanical strength drops significantly, ultimately leading to fragile, brittle ends and a noticeably worse overall appearance.

[0003] In traditional haircuts, conventional scissors only cut hair mechanically, without any subsequent treatment of the ends. While this cutting method can change the length of the hairstyle, it has minimal impact on the physical structure and health of the hair itself. As a result, the cuticles of the hair are raised, and the cracks expand during subsequent combing and blow-drying. The split end rate rises again within 1-2 weeks after the cut, and the cut ends become the starting point for splitting and breakage, leading to new splits. Therefore, even with conventional haircutting scissors, the split end rate remains high.

[0004] To improve split ends, traditional scissors alone are not enough; additional treatments such as hair masks, hair oils, and hot perms are necessary. However, these methods require a long time to be effective and increase costs. Summary of the Invention

[0046] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0047] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "including," "comprising," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0048] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, an electrically heated hair clipper is provided, including a first cutting blade 1 and a second cutting blade 1 that are hinged together, and also includes: a heating tube, a temperature sensor, and a control circuit;

[0049] At least one of the first shear blade 1 and the second shear blade 2 is configured as a heated shear blade. A first groove 31 is formed on the outer surface of the heated shear blade along the longitudinal direction of the cutting edge. A heating tube 3 is fixedly installed in the first groove 31 to form an external heat seal in the shearing zone. Figure 1 As shown.

[0050] A second groove 32 is longitudinally formed on the inner side of the heated shear blade behind the cutting edge. A temperature sensor is fixedly installed in the second groove 32 to collect the temperature of the shearing area. Figure 2 As shown.

[0051] The first groove 31 and the second groove 32 are connected to each other at the end away from the blade tip to form a common wiring port;

[0052] Starting from the wiring port, a continuous hollow channel 4 is provided inside the heating shear and the corresponding handle body. The hollow channel 4 begins at the wiring port of the heating shear, passes through the handle, and extends to the tail of the handle. The power supply wire of the heating tube and the signal wire of the temperature sensor enter the hollow channel 4 through the wiring port and exit together from the tail of the handle to connect to an external power supply and control circuit. Figure 3 As shown.

[0053] The control circuit includes: a main controller, a power supply circuit, a power output voltage acquisition circuit, a temperature acquisition circuit, a Bluetooth module, a button circuit, and a display. The main controller is connected to the power supply through the power supply circuit to obtain working power, and is also connected to the power supply through the power output voltage acquisition circuit to monitor the power supply voltage. The main controller is also connected to the button circuit, the display, and the Bluetooth module to achieve human-computer interaction and wireless communication. The main controller is also connected to a temperature sensor through the temperature acquisition circuit. The main controller is also connected to the heating element to drive the heating element and keep the temperature of the cutting zone constant at a preset value that seals the hair tip surface and prevents it from being scorched. Figure 4 As shown.

[0054] In this embodiment, the control circuit of this application is connected to the power supply via a power-drawing circuit, thereby ensuring safety and avoiding the need to draw 12V power from a power bank. U2 and U7 respectively provide 5V and 3.3V to power the entire system, converting the external DC source into the stable operating voltage required by the electric heating scissors.

[0055] The Bluetooth module in the control circuit of this application can also communicate with the user terminal device for data and command interaction. The terminal can acquire the actual temperature collected by the temperature sensor and issue commands.

[0056] The display shows the temperature from the temperature sensor, allowing the hairdresser to instantly view the temperature collected by the sensor and control the heating element accordingly.

[0057] The power supply output voltage acquisition circuit obtains the power supply's output voltage, allowing real-time monitoring of whether the output voltage remains within a safe range. Upon detecting a voltage drop, PD renegotiation, or low battery, the heating power is immediately reduced or an alarm is triggered to prevent temperature runaway and sealing failure due to insufficient power supply, while simultaneously protecting the power supply and the entire power circuit.

[0058] In the aforementioned electrically heated hair clippers, the electric hair clippers of this application have a first groove longitudinally formed along the blade edge on the outer side of any one of the blades to house a heating element. The heating element is controlled by a control circuit, and a temperature sensor is placed on the inner side. The temperature of the sensor is acquired by a temperature acquisition circuit within the control circuit. This allows for manual adjustment of the heating element temperature based on the actual acquired temperature of the scissor blade edge, bringing the blade edge temperature to a target level. Therefore, during haircutting, not only can the length be trimmed, but the hair ends are also sealed during the cutting process, preventing frizz during subsequent combing, reducing the incidence of split ends, and significantly delaying new splits. This allows fragile, easily broken hair to re-lock in moisture and nutrients, thereby restoring its strength, resilience, and elasticity.

[0059] This application's portable DC energy storage device can be used as a power source to enable one-step, digital, and portable high-frequency salon operations, combining safety, convenience, and hair care effects.

A first branch and a second branch are led out from the connection line between the VBUS pin of USB1 and U2, and connected to diode D1 and diode C1 respectively before being grounded. The VOUT pin of U2 is connected to the IN pin of U9. The GND pin of U2 is connected to the GND pin of U9. A third branch is led out from the connection line between the VOUT pin of U2 and the IN pin of U9, connected to capacitor C15, and then connected to the GND pin of U9.

[0065] In one embodiment, such as Figure 6 As shown, the temperature acquisition circuit includes: amplifier U7, resistors R16, R27, R28, R23, capacitors C9 and C13, and diode D3;

[0066] The inverting input terminal of amplifier U7 is connected to resistor D16. An eighth branch is led out from the connection line between the inverting input terminal of amplifier U7 and resistor D16. The eighth branch is connected to diode D3 and then grounded. C9 is connected to both sides of diode D3. The non-inverting output terminal of amplifier U7 is connected to resistor R27 and then grounded.

[0067] The output terminal of the amplifier U7 is connected to the resistor R23. A ninth branch is led out from the connection line between the output terminal of the amplifier U7 and the resistor R23. The ninth branch is connected to the resistor R28 and then connected to the inverting input terminal of the amplifier U7.

[0068] The tenth branch of the output terminal of the resistor R23 is connected to the capacitor C13 and then grounded.

[0069] In one embodiment, the control circuit further includes: an indicator light and a buzzer. For example... Figure 7 The diagram shown is a detailed circuit diagram of the indicator light. Figure 8 This is a detailed circuit diagram of the buzzer. Indicator lights D4, D5, D6, D7, and D8 enable human-machine interaction. Buzzer B1 provides the alert tone.

[0070] like Figure 9 This is the circuit diagram of the main controller; the main control unit U5 is responsible for the overall function control of the machine. For example... Figure 10 The fourth part of the button circuit module, SW3, implements the button input function. Figure 11The third part of the detailed circuit diagram for the Bluetooth module shows that the U3 module and its peripheral circuits are responsible for Bluetooth communication, unit monitoring, and parameter calibration. Figure 12 This is a power supply output voltage acquisition circuit. R9 and R11 are used to divide and acquire the power supply voltage.

[0071] In one embodiment, the outer surfaces of the first scissor blade 1 and the second scissor blade 2 are provided with a heat-insulating film. This provides heat insulation, preventing the barber from being burned by the heated blades.

[0072] In one embodiment, the heating tube 3 is a PCT, which is a thermistor heating element.

[0075] In one embodiment, the power source is a portable DC energy storage device. The portable DC energy storage device can be a power bank.

[0076] This electric hair clipper utilizes the hair's own keratin to directly seal the hair ends, while simultaneously trimming with effective heat. It effectively eliminates split ends and delays the formation of new split ends, resulting in naturally shiny hair and significantly improved volume. Split ends can be sealed off.

[0077] The time required for electrically heated hair clippers is the same as that for traditional haircuts. From cutting the hair and sealing the ends to the final touches, it can be done in just one step.

[0078] Microscopic examination of the hair revealed that the tips of hair cut with ordinary hairdressing scissors were more open and rougher than those cut with electrically heated hairdressing scissors. The sealed design makes the hair smoother and tighter. This allows the hair to better retain all its material, and the tips are better protected. Table 1 shows a comparison of the split ends of hair cut on the same person using ordinary hairdressing scissors and the electrically heated hairdressing scissors described in this application:

[0079] Table 1

[0080]

[0081] like Figure 13 This is a diagram of the split ends of a hair shaft, showing a rough cuticle and damaged fibrils. Figure 14 This is a diagram showing the tip of a haircut using regular barber scissors. Damaged fibers are cut at the tip, and the cuticle becomes rough. (Example:) Figure 15The end view of the hair cutting using the electrically heated scissors of this application shows that the cuticle is smooth and shiny, and the fiber protofibrils are protected.

[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
