Description

Technical Field

[0001] This utility model relates to a multifunctional comb. Background Technology

[0002] Combs, as a daily grooming product, are primarily used for detangling hair and massaging the scalp. Their structure is typically simple, consisting mostly of fixed-shape comb teeth and a handle. With the diversification of personal care needs, some combs have gradually integrated other functions, such as heating, ion generators, and scalp massage. However, existing multi-functional combs generally suffer from the following shortcomings: Existing multi-functional combs typically come with specific functional modules integrated at the factory, such as heating elements or ion generators, and users cannot replace or upgrade these functions as needed. If different functions are required, multiple different combs often need to be purchased, which not only increases the cost of use but also makes them inconvenient to carry and store.

[0003] Most of the functional modules of existing combs are fixedly connected to the comb body. Once one of the functional components is damaged, the entire comb often needs to be replaced, resulting in high maintenance costs and wasted resources.

[0004] In the existing technology, the power supply and control circuit of functional components are integrated into a single design, lacking a unified interface standard, which makes it impossible to achieve the universality, interchangeability and scalability of functional modules. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional comb with expandable functions and modular replacement capability.

[0006] The purpose of this utility model is achieved as follows: A multifunctional comb includes a comb, a battery, a circuit board, and a functional module. The comb has an installation opening, and a power supply contact is provided on the inner wall of the installation opening. The battery and the circuit board are disposed inside the comb, and the power supply contact and the battery are electrically connected to the circuit board respectively. The functional module is provided with conductive contacts, the functional module is shaped to match the mounting port, the functional module is detachably mounted on the mounting port, the conductive contacts and the power supply contacts are electrically connected, the battery supplies power to the functional module, and the circuit board controls the start, stop and operation of the functional module.

[0007] By opening installation ports and setting power supply contacts on the comb body, combined with detachable functional modules, a modular design is achieved. Users can quickly replace different functional modules according to actual needs, which significantly improves the comb's functional expandability and applicability.

[0008] The electrical connection method between the power supply contacts and the conductive contacts enables the battery to provide stable power to different functional modules, and the circuit board uniformly controls the start-up, shutdown and operation of the modules, improving the product's compatibility and intelligence.

[0009] The objective of this utility model can also be achieved by the following technical measures: Furthermore, the comb includes a comb body and a handle. The comb body has the mounting port, and the power supply contact is provided on the inner wall of the comb body corresponding to the mounting port. The battery and circuit board are disposed inside the handle.

[0010] By placing the mounting port on the comb body and placing the battery and circuit board inside the handle, the weight is concentrated in the handle while ensuring the comb body remains lightweight, thus improving the user's grip and comfort.

[0011] The power supply contacts are located on the inner wall of the comb body at the corresponding installation port, allowing the functional modules to be directly plugged in and electrically connected, avoiding additional wiring and improving the convenience of installation and the reliability of use.

[0012] Furthermore, it also includes a comb holder and a drive device, wherein the comb holder includes a mounting base and comb teeth, and the comb teeth are spaced apart on the mounting base; The comb body is provided with movable openings at intervals along the periphery of the mounting opening, the mounting base is movably disposed in the movable openings, and the comb teeth extend outwards; The drive device is installed inside the comb and electrically connected to the circuit board. The drive device is connected to the mounting base. When the drive device is working, it drives the mounting base to swing, thereby driving the comb teeth to swing and producing a massage effect.

[0013] By incorporating a drive mechanism within the comb body, the comb teeth oscillate, causing them to either converge toward the center of the comb or expand outwards, mimicking the pinching effect of fingers and producing a massage effect. This not only enhances the comb's care function but also promotes scalp blood circulation and improves the user's scalp health.

[0014] The comb teeth holder is movably connected to the comb body through a movable opening. The structure is compact and the movement is flexible. While ensuring the normal combing function, it adds an extra massage function, enriching the functional experience of the comb.

[0015] Furthermore, the comb body is provided with comb teeth at intervals along the periphery of the mounting opening.

[0016] The comb teeth are spaced apart around the comb body mounting port, so that it can still be used as a regular comb when the user does not install the functional module, maintaining the product's basic combing function.

[0017] Furthermore, the handle is equipped with control buttons and a charging port, which are electrically connected to the circuit board.

[0018] The handle features control buttons and a charging port, allowing users to easily operate and control different functional modules. It also supports battery charging, extending the comb's lifespan.

[0019] The control buttons are electrically connected to the circuit board, allowing users to easily start, stop, and switch modes of the functional modules, making the operation intuitive and convenient.

[0020] Furthermore, the functional module is a liquid-pushing care module with liquid-pushing function and phototherapy function, or a spraying device with spraying function and phototherapy function, or a scalp detection module with photography function and data uploading function, or a plasma care module with plasma care function, or a phototherapy care module with multiple photon combination care function, or a laser hair growth module with laser care function. The functional module is detachably mounted on the mounting port, allowing the conductive contacts and the power supply contacts to be electrically connected. The battery supplies power to the functional module, and the circuit board controls the start, stop, and operation of the functional module.

[0021] By designing functional modules in various types, such as liquid dispensing module, spraying device, scalp detection module, plasma care module, photon care module, and laser hair growth module, it can meet the diverse scalp and hair care needs of users and achieve "one comb for multiple uses".

[0022] All functional modules are detachably installed on the mounting port, with a unified power supply and control method, enabling users to quickly switch between different care functions according to the scenario, greatly improving the intelligence level of the comb and the user experience.

[0023] Furthermore, the plasma care module includes a base and a plasma light source assembly. The plasma light source assembly includes a bulb capable of generating plasma, an RF power amplifier, and a control circuit board. The bulb is filled with inert gas. The top of the base has a bulb receiving cavity. The side wall of the base is provided with conductive contacts. The conductive contacts, the RF power amplifier, and the control circuit board are placed inside the base and are electrically connected. The bulb is placed inside the bulb receiving cavity and is electrically connected to the RF power amplifier.

[0024] By setting a bulb housing cavity at the top of the base, the bulb can be easily assembled and replaced; conductive contacts on the side wall enable plug-in power supply, avoiding the inconvenience of traditional soldering methods; at the same time, the bulb is filled with inert gas, which not only ensures the stable generation of plasma, but also produces different colors due to different gases, improving the visual appeal; in addition, the RF power amplifier and control circuit board are built into the base, making the overall structure compact, reducing the size, and facilitating portable applications.

[0025] Furthermore, the plasma care module includes a base, a lens, and a plasma light source assembly. The plasma light source assembly includes a conductive sheet, electrodes, an RF power amplifier, and a control circuit board. The RF power amplifier and the control circuit board are placed inside the cavity of the base. The conductive contacts are provided on the side wall of the base, and the conductive contacts are electrically connected to the RF power amplifier. The base is provided with an inert gas receiving cavity with an open top, the lens is disposed on the inert gas receiving cavity and closes the inert gas receiving cavity, and the inert gas receiving cavity is filled with inert gas. The conductive sheet is placed inside the inert gas containment cavity, the electrode is placed inside the base, one end of the electrode is connected to the conductive sheet, and the other end of the electrode is electrically connected to the RF power amplifier.

[0026] By integrating the RF power amplifier and control circuit board into the internal cavity of the housing, and employing a structure design of conductive sheets and electrodes, along with a top-sealed inert gas containment chamber, plasma can be generated without the need for traditional light bulbs. This design achieves miniaturization and structural simplification, while avoiding the problems of fragile and short-life bulbs. Furthermore, the use of inert gas allows for a variety of plasma emission colors, expanding application scenarios.

[0027] Furthermore, the liquid-pushing nursing module includes a phototherapy component, a liquid aspiration device, a liquid dispenser, a base and a face cover. The base is provided with a liquid storage bottle cavity, and the base is provided with a bottle nozzle connection cavity corresponding to the position of the liquid storage bottle cavity. The bottle nozzle connection cavity has a liquid inlet. The liquid dispenser has a built-in liquid dispensing chamber, and the liquid dispenser is provided with a liquid inlet and a liquid outlet that communicate with the liquid dispensing chamber. The liquid dispenser is located in the inner cavity of the base. The liquid extraction device is installed in the inner cavity of the seat body, the inlet of the liquid extraction device is connected to the liquid inlet, and the outlet of the liquid extraction device is connected to the liquid guide inlet; The phototherapy component is disposed in the inner cavity of the seat, the face cover is connected to the seat, the liquid outlet extends outward through the face cover, and the face cover is provided with a light-transmitting area corresponding to the position of the phototherapy component; The conductive contacts are provided on the side wall of the seat, and the liquid aspiration device and phototherapy component are electrically connected to the conductive contacts respectively.

[0028] The fluid delivery module integrates the phototherapy components, fluid extraction device, and fluid dispenser into the base, enabling automatic extraction and distribution of the nursing fluid and synergistic effects with phototherapy, thus improving nursing efficiency and ease of use. The fluid outlet passes through the cover for easy output of the nursing fluid, and the conductive contact design on the side wall of the base supports electrical connection between the module and external devices, enabling unified power supply and control, and enhancing the overall integration and safety of the functions.

[0029] Furthermore, the injection device includes a base, a motor, a diaphragm, a compression assembly, and a valve body. The base is provided with a compression channel and a liquid inlet channel. The junction of the outlet of the compression channel and the outlet of the liquid inlet channel forms an injection chamber. The diaphragm is movably disposed at the outlet of the injection chamber. The base has an injection port that communicates with the outlet of the injection chamber. The valve body is installed in the liquid inlet channel, and the valve body controls whether liquid enters the liquid inlet channel; The compression assembly is disposed in the seat body. The compression assembly includes a transmission device for converting rotational motion into linear motion and a compression rod. The compression rod is slidably disposed in the compression channel and is connected to the transmission device. The motor is installed in the base, the output shaft of the motor is connected to the transmission device, and the side wall of the base is provided with conductive contacts, and the motor is electrically connected to the conductive contacts; The motor drives the compression rod to rise and fall along the compression channel through the transmission device. When the compression rod rises, the injection chamber forms a negative pressure. Under the action of the negative pressure, the diaphragm seals the outlet of the injection chamber. At the same time, the valve body opens the liquid inlet channel, and the external liquid enters the injection chamber along the liquid inlet channel. When the compression rod descends, it squeezes the liquid in the injection chamber. The liquid in the injection chamber pushes the diaphragm to open the outlet of the injection chamber and spray it outward along the injection port. At the same time, the valve body closes the liquid inlet channel.

[0030] The compression assembly is driven by a motor, which raises and lowers the compression rod, creating an alternating process of negative pressure liquid intake and positive pressure spraying within the spray chamber. This structure allows the liquid to be evenly drawn in and sprayed out at high speed, significantly improving the spraying effect. It overcomes the shortcomings of existing technologies where hair care liquids and water can only be discharged by gravity or simple separation, achieving fine atomization and uniform distribution, thus enhancing the care effect.

[0031] The beneficial effects of this utility model are as follows: This invention achieves a modular design by opening an installation port and setting power supply contacts on the comb body, combined with detachable functional modules. Users can quickly replace different functional modules according to actual needs, which significantly improves the comb's functional expandability and applicability.

[0032] This utility model, through the electrical connection method between the power supply contact and the conductive contact, enables the battery to stably supply power to different functional modules, and the circuit board to uniformly control the start-up, shutdown, and operation of the modules, thereby improving the product's compatibility and intelligence.

[0033] This invention, by incorporating a driving device within the comb body, causes the comb teeth to oscillate, resulting in the comb teeth retracting towards the center of the comb body or expanding outwards, simulating the effect of finger grasping and producing a massage effect. This not only enhances the comb's care function but also promotes scalp blood circulation and improves the user's scalp health. Attached Figure Description
