Description

Technical Field

[0001] This application relates to the field of hair styling devices, and in particular to a multifunctional styling tool with an electrically powered accessory that is activated by pressing. Background Technology

[0002] As people's living standards improve, multi-functional styling tools (such as curling irons and straighteners) have become increasingly popular household items. These tools allow for easy curling and straightening of hair, enabling users to blow-dry and style their hair independently, making them very convenient. Multi-functional styling tools can be used as both hair dryers and styling tools (e.g., curling and straightening functions). To achieve longer-lasting styles, current technology utilizes electrically powered accessories, which incorporate heating elements (such as PTC or MCH) to provide both continuous heating and hot air. These electrically powered accessories are powered by the main unit, and to ensure user safety, they typically include additional mechanical mechanisms or detection devices to enhance safety.

[0003] In existing technologies, power to the electrical accessories and the main body is typically achieved through conductive spring pins. These conductive spring pins are embedded quite deeply within the main body, approximately 15mm below the air outlet end face, ensuring conductivity upon installation of the electrical accessories. The disadvantages of this method are that it is prone to poor contact, sparking, and low safety. Utility Model Content

[0019] Reference Figures 1 to 3 As shown, the multi-functional molding tool with an electrically powered accessory disclosed in this application includes a main unit 100, a connector 200, and a detachable accessory 300. The first end of the connector 200 is connected to the main unit 100, and the second end of the connector 200 is provided with a conductive part. The detachable accessory 300 is provided with a conductive contact piece, and the connector 200 is provided with a mechanical switch. When the conductive part and the conductive contact piece are combined, the mechanical switch needs to be triggered to achieve power supply.

[0020] In detail, the main unit 100, as the core control unit of the modeling machine, incorporates key components such as a power management module and control circuitry, responsible for providing power and control signals to the entire modeling machine. The connector 200 connects the main unit 100 to the detachable accessory 300. The first end of the connector 200 connects to the main unit 100, ensuring a stable electrical connection with the internal circuitry of the main unit 100. The second end of the connector 200 has a conductive part, and the detachable accessory 300 is correspondingly equipped with conductive contact pieces (not shown). When the accessory 300 and the connector 200 are installed, the conductive part and the conductive contact pieces can precisely align and engage, thereby achieving circuit continuity.

[0021] The conductive part 210 can be a spring pin or a spring piece, with several spring pins arranged circumferentially along the second end of the connector 200. At least one mechanical switch is provided and located between the spring pins. The mechanical switch is automatically triggered when the spring pins engage with the conductive contact piece, thus energizing the device. Once triggered, the mechanical switch sends an energizing signal to the main unit, connecting the molder's circuitry and enabling automatic energization. This automatic energization design, requiring no manual operation, greatly simplifies the user's workflow. Users only need to install the accessories, and the molder will automatically energize and operate, significantly improving ease and smoothness of use. Simultaneously, the mechanical switch's location between the spring pins fully utilizes the internal space of the connector, making the overall structure more compact and rational. Furthermore, it allows for timely and accurate sensing of the connection status between the conductive part and the conductive contact piece, ensuring the reliability and stability of the energizing function.

[0022] In one specific embodiment, a plurality of spring pins 210 are arranged circumferentially at the second end of the connector 200. The second switch 211 is a spring-reset mechanical switch, which can connect or disconnect the circuit by pressing or other means. At least one second switch 211 is provided and located among the plurality of spring pins 210. When the detachable accessory 300 is installed, the conductive contact piece on the detachable accessory 300 contacts the spring pins 210, and at the same time the second switch 211 is pressed, so that the circuit is connected and the detachable accessory 300 is energized. When the detachable accessory is removed, the mechanical switch 211 springs up to disconnect the power.

[0023] Several spring pins 210 are arranged circumferentially along the second end of the connector 200, significantly increasing the conductive contact area. Compared to a single conductive component, the larger contact area effectively reduces contact resistance, minimizes energy loss during transmission, and ensures a stable and sufficient power supply for the molding tool during operation, guaranteeing its stable operation. The circumferentially distributed spring pins provide support and fixing force to the accessory 300 from multiple directions when it is connected to the connector 200. This multi-directional force connection method makes the connection between the accessory 300 and the connector 200 more robust and reliable. Even if the molding tool is subjected to external shaking or slight impact during use, it can effectively avoid poor conductive contact caused by loose connections, improving the overall reliability and durability of the molding tool. The layout of multiple spring pins 210 is equivalent to a redundant design. Even if individual spring pins malfunction, such as due to wear or deformation, the other normally functioning spring pins can still maintain basic conductivity. This ensures that the molding machine will not completely fail to work due to problems with local conductive components, reducing the probability of the molding machine stopping due to conductivity failure and improving the overall stability of the product and the continuity of user operation.

[0024] In other embodiments, the mechanical switch can also be a mechanical switch 202 located on the outer shell of the connector. After the spring pin 210 engages with the conductive contact, the mechanical switch 202 is manually triggered to energize the device. Once the spring pin 210 and the conductive contact are engaged, establishing circuit continuity, the user needs to manually operate the mechanical switch located on the outer shell of the connector to ultimately energize the molder. This manual triggering mode provides users with greater operational autonomy. Users can choose whether to energize immediately after the attachments are connected, based on actual usage needs, increasing the flexibility of product use. For example, when the user needs to debug, inspect, or prepare the molder, they can first complete the attachment 300 connection and then manually trigger the switch to energize, avoiding unnecessary energy consumption and safety risks. Simultaneously, placing the mechanical switch on the outer shell of the connector makes it easy for users to quickly locate and operate, improving user convenience and comfort.

[0025] The detachable accessory 300 is equipped with multiple air outlets, with a minimum distance of more than 10mm between the conductive part and the air outlet. This prevents the airflow (especially high-temperature airflow) from directly contacting the conductive parts, reducing the risk of short circuits or the possibility of the conductive parts aging due to high temperatures. For humid airflow, sufficient distance prevents moisture from condensing on the surface of the conductive parts, reducing the risk of short circuits. In addition, the air outlet adopts a streamlined guide channel design, which, while ensuring efficient airflow discharge, further reduces the impact of airflow on the conductive parts by changing the airflow direction. Seven spring pins are provided, and the mechanical switch and the spring pins are evenly distributed along the second end circumferentially. When the detachable accessory is removed, the mechanical switch disconnects to cut off power. The seven spring pins are evenly distributed to form a ring-shaped conductive contact, which, compared with the traditional linear arrangement, reduces contact resistance, reduces power loss, provides uniform contact pressure, makes the connection more stable, and improves vibration resistance.

[0026] The main unit includes a connecting protrusion 101, and the connector includes a connecting groove 201. An elastic component is connected below the connecting protrusion 101, allowing the connecting protrusion 101 to connect with the connecting groove 201. Specifically, a stainless steel helical spring is connected below the connecting protrusion 101. During installation, the connecting protrusion 101 compresses the spring under force, and after entering the connecting groove 201, the spring rebounds and locks.

[0027] The mechanical switch 202, the connecting groove 201, and the connecting protrusion 101 are located on the same axis. This design ensures more even force transmission when the main unit 100 is connected to the accessory 300, effectively preventing loosening due to uneven force. When the accessory 300 is connected to the main unit 100, the connecting protrusion 101 and the connecting groove 201 cooperate to form a preliminary positioning, and then are tightened to ensure that the molding device will not shake or fall off during operation.

[0028] The main unit 100 also includes a control unit 102, through which the user can operate the molding device. The main unit may also include an electrical connector, which can be detachably connected to a power supply assembly, facilitating the carrying of the molding device.

[0029] When users need to replace accessories, hold the accessory and gently pull it outwards to disengage the clip on the accessory from the slot on the main unit. Then, select the desired accessory, align the clip on the accessory with the slot on the main unit, ensuring the locating pin is inserted into the locating hole, and gently push the accessory in until the clip is fully engaged in the slot. The accessory installation is complete. Select the appropriate working mode according to the type of accessory installed. For example, after installing the curling iron, select the curling mode on the main unit's control panel, set the appropriate temperature and time, then wrap the hair around the curling iron and wait for the set time to finish to complete the curling style. If the power cord is found to be damaged during use, the main unit's power connector can be disconnected from the low-voltage output of the power supply unit, allowing for quick and easy replacement of the power supply unit alone.

[0030] Although preferred embodiments of this application have been described, those skilled in the art can make various modifications and variations to the embodiments of this application without departing from the spirit and scope of the embodiments of this application. Thus, these modifications and variations are also within the protection scope of this application.
