Description

Technical Field

[0001] This utility model relates to the field of hair styling device technology, and specifically to a hair comb. Background Technology

[0002] As people's living standards improve, perming and hair styling have become an indispensable part of women's lives. Hair styling requires various tools for perming, curling, and straightening, and while there are many types, their functions are often limited. Usually, people need to go to a hair salon to receive services from professionals. Of course, women can also purchase various hair styling tools themselves, allowing them to enjoy the fun of perming at home.

[0003] Chinese patent CN209628894U discloses a detachable hair curler, including a handle for gripping, a control switch on the surface of the handle, a latching part at one end of the handle, and an output copper plate near the latching part. The detachable hair curler also includes a straightening component, one end of which is recessed inward to form a first interface that engages with the latching part. Near the first interface is a first input copper plate that cooperates with the output copper plate to provide power to the straightening component. This technical solution independently sets up the hair curler and the straightening component, and achieves detachment from the handle and functional replacement based on the adaptable first interface and latching part.

[0004] In the aforementioned prior art, an output copper plate is disposed near the latching part, and a first input copper plate is disposed near the first interface part, forming an electrical connection through their cooperation. This connection method is quite unstable. Over a long period of use, misalignment may occur between the latching part and the first interface part, and metal fatigue and oxidation of the copper plate may easily lead to malfunctions such as poor contact, affecting the use of the product.

[0005] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0006] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a hair comb that is structurally reasonable, flexible in use, and stable and reliable.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] The present invention discloses a hair comb, comprising a handle and a combing device. The handle is provided with a socket, the socket having a slot, and the slot having a power-connecting structure. The combing device is provided with a plug, the plug having an opening, and the opening having a power-receiving structure. The plug can be inserted into the slot to pair and connect the power-connecting structure and the power-receiving structure. A locking structure is provided between the socket and the plug, allowing the combing device to be detachably mounted on the handle.

[0009] The handle has a slot via a socket, and the combing device has a plug that mates with the slot. The plug is inserted into the slot and paired with the socket. It is understood that the slot and the plug have the same cross-section, for example, both the slot and the plug have a circular cross-section. After the plug is inserted into the slot, the plug and the socket form a form-position fit, and then a detachable connection is formed by a locking structure, resulting in a high connection strength.

[0010] Furthermore, the fit between the plug and the socket can improve the stability of the fit between the plug-in structure and the receiving structure. Specifically, the plug-in structure is set in the slot and the receiving structure is set in the opening of the plug. After the plug is connected to the socket, the plug-in structure and the receiving structure are paired to form an electrical connection, which improves the connection stability and insulation and can effectively avoid problems such as poor contact.

[0011] According to the above scheme, the plug-in structure includes several conductive pins, and a plug-in bracket is provided inside the handle. Several conductive pins are arranged on the plug-in bracket. The socket has several pin holes, and several conductive pins pass through corresponding pin holes, so that the first end of the conductive pin is positioned in the slot. The several conductive pins arranged on the plug-in bracket form the plug-in structure. The plug-in bracket is easy to assemble; after the plug-in bracket is paired and connected to the socket, several conductive pins pass through the pin holes and are correspondingly positioned in the slot.

[0012] According to the above scheme, the power supply bracket is provided with several distribution holes, and the second ends of several conductive pins are inserted into the corresponding distribution holes. The handle contains a power supply assembly, and the conductive pins are grouped and welded together to be electrically connected to the power supply assembly. It is understood that the power supply structure of this utility model adopts a pin-type connection. The power supply bracket has two rows of distribution holes for inserting conductive pins, and then the two groups of conductive pins are welded together to form a live wire terminal and a neutral wire terminal, which are then connected to the power supply assembly via wires. It is understood that typically a live wire or neutral wire is configured with at least two conductive pins. Multiple conductive pins can improve the electrical connection stability between the power supply structure and the receiving structure. Of course, they can also distribute the total current, avoiding oxidation problems caused by excessive current passing through a single conductive pin.

[0013] According to the above scheme, the power receiving structure includes several pin sockets, a connector is provided in the opening of the plug, several sockets are arranged on the connector, and several pin sockets are inserted into the corresponding sockets; the combing device contains functional components, and several pin sockets are grouped and welded to the functional components for electrical connection. Similarly, the plug contains pin sockets arranged through several sockets on the connector. These pin sockets are divided into two groups and welded to form a live wire terminal and a neutral wire terminal, which are then connected to the functional components via wires. The pairing of the pin sockets and conductive pins forms a tight structural fit to ensure stable electrical connection. It is understood that the above-mentioned combing devices include hair straighteners, curling combs, and flat iron combs, etc., and correspondingly, different combing devices are equipped with corresponding functional components, which are usually heating modules.

[0014] Furthermore, to ensure the plug and slot are compatible, and to facilitate the assembly of the comb device and handle, the outer edge of the plug has a cut surface, and the slot has a guide block. When the guide block mates with the cut surface, the plug can be inserted into the slot axially, allowing several conductive needles to align and be inserted into the needle holder. Of course, the cross-sections of the slot and plug can be non-circular, which also ensures accurate matching of the conductive needles and the needle holder.

[0015] According to the above scheme, the needle holder is a hollow tube with an open end facing the insertion structure. Several conductive petals are provided on the open end of the needle holder, and these conductive petals are spaced at equal angles around the inner hole of the needle holder. Preferably, the conductive petals on the open end of the needle holder allow the conductive needle to contact and connect with the conductive petals after insertion, ensuring better coverage and fit of the conductive needle and thus guaranteeing electrical connection stability. It is understood that the needle holder and the conductive petals are integrally stamped, and the tail end of the needle holder is tapered for easy welding.

[0016] According to the above scheme, the locking structure includes a pin and a positioning hole. The socket has a keel with a lock hole that passes through the keel and connects to the slot. The plug has a positioning hole, and the pin is movably inserted through the lock hole. When the plug is inserted into the slot, the lower end of the pin can be inserted into the positioning hole. The keel is used to install the locking structure. The outer diameter of the keel is larger than that of the socket and has a certain thickness, thus forming a lock hole for installing the pin. The pin can move a certain distance along the lock hole. It can be understood that the direction of pin movement is perpendicular to the insertion direction of the plug, or the pin is arranged radially along the handle. Furthermore, when the plug is inserted into the socket slot along the axial direction of the handle, the positioning hole and the lock hole are opposite each other, allowing the pin to be inserted into the positioning hole, thereby locking the plug inside the socket.

[0017] According to the above scheme, the latch structure also includes a knob ring and a spring pin bracket. A positioning seat is provided on the keel, and the lock hole is opened on the positioning seat. The spring pin bracket is assembled on the positioning seat and slidably connected thereto. The pin is assembled on the spring pin bracket, and a spring is provided between the spring pin bracket and the positioning seat. The knob ring is rotatably fitted onto the keel, and the upper end of the pin abuts against the inner wall of the knob ring, and the inner wall of the knob ring has a clearance groove. It can be understood that the keel and the socket are integrally formed, and the keel has a hollow groove structure to reduce weight and material usage. A positioning seat is provided on the keel to provide the lock hole. Further, the spring pin bracket has a U-shaped structure and is inverted on the positioning seat, allowing the elastic bracket to slide radially on the positioning seat, thereby allowing the pin to be inserted into or disengaged from the positioning hole.

[0018] Furthermore, the knob ring is rotatably fitted onto the keel. In the normal state, the upper end of the pin corresponds to the clearance groove, causing the lower end of the pin to retract into the lock hole, at which point the plug can be inserted into or removed from the socket. Rotating the knob ring pushes the pin through its inner wall, causing the lower end of the pin to insert into the positioning hole, thus fixing the comb device to the handle.

[0019] According to the above scheme, the power assembly includes a battery and a charging interface. The battery is located inside the handle, and the charging interface is located at the rear end of the handle. The handle contains a circuit board, which is connected to the battery and the charging interface via lines. The side wall of the handle has control buttons, which are paired and connected to the circuit board.

[0020] This utility model discloses a hair comb with a handle having a slot provided through a socket. The combing device has a plug that is compatible with the slot. The plug is inserted into the slot to form a mating connection with the socket, and then a detachable connection is formed through a locking structure, resulting in high connection strength. This allows the plug-in structure and the receiving structure to be mated and connected, ensuring good safety and stability, and effectively avoiding problems such as poor contact.

The handle 1 is provided with a socket 11, which has a slot and a power-connecting structure inside the slot. The combing device 2 is provided with a plug 21, which has an opening and a power-receiving structure inside the opening. The plug 21 can be inserted into the slot to pair and connect the power-connecting structure with the power-receiving structure. A locking structure is provided between the socket 11 and the plug 21 to allow the combing device 2 to be detachably mounted on the handle 1.

[0031] The handle 1 has a slot provided through the socket 11, and the comb device 2 has a plug 21 that is adapted to the slot. The plug 21 is inserted into the slot and paired with the socket 11. It can be understood that the slot and the plug 21 have the same cross-section, for example, both the slot and the plug 21 have a circular cross-section. After the plug 21 is inserted into the slot, the plug 21 and the socket 11 form a form-position fit, and then a detachable connection is formed by the locking structure, resulting in a high connection strength.

[0032] Furthermore, the cooperation between the plug 21 and the socket 11 can improve the stability of the cooperation between the plug-in structure and the power-receiving structure. Specifically, the plug-in structure is set in the slot, and the power-receiving structure is set in the opening of the plug 21. After the plug 21 is connected to the socket 11, the plug-in structure and the power-receiving structure are paired to form an electrical connection, which improves the connection stability and insulation and can effectively avoid problems such as poor contact.

[0033] The plug-in structure includes a plurality of conductive pins 12. A plug-in bracket 13 is provided inside the handle 1, and the plurality of conductive pins 12 are arranged on the plug-in bracket 13. The socket 11 has a plurality of pin holes 14, and the conductive pins 12 pass through the corresponding pin holes 14, thereby placing the first end of the conductive pin 12 in the slot. The plurality of conductive pins 12 arranged on the plug-in bracket 13 form the plug-in structure. The plug-in bracket 13 is easy to assemble; after the plug-in bracket 13 is paired and connected to the socket 11, the plurality of conductive pins 12 pass through the pin holes 14 and are correspondingly placed in the slot.

[0034] The plug-in bracket 13 is provided with several distribution holes 15, and the second ends of several conductive pins 12 are inserted into the corresponding distribution holes 15. The handle 1 is provided with a power supply component, and the conductive pins 12 are grouped and welded together to be electrically connected to the power supply component. It is understood that the plug-in structure of this utility model adopts a pin-type plug-in connection. The plug-in bracket 13 is provided with two rows of distribution holes 15, each with conductive pins 12 inserted. The two groups of conductive pins 12 are then welded together to form a live wire terminal and a neutral wire terminal, which are then connected to the power supply component via wires. It is understood that typically a group of live or neutral wires is configured with at least two conductive pins 12. Multiple conductive pins 12 can improve the electrical connection stability between the plug-in structure and the receiving structure. Of course, they can also distribute the total current, avoiding oxidation problems caused by excessive current passing through a single conductive pin 12.

[0035] The power receiving structure includes several pin sockets 22. A connector 23 is provided inside the opening of the plug 21, and several insertion holes 24 are arranged on the connector 23. The pin sockets 22 are inserted into the corresponding insertion holes 24. The combing device 2 contains functional components, and the pin sockets 22 are electrically connected to the functional components after being grouped and welded together. Similarly, the plug 21 contains pin sockets 22 arranged through the insertion holes 24 on the connector 23. These pin sockets 22 are divided into two groups and welded together to form a live wire terminal and a neutral wire terminal, which are then connected to the functional components via wires. The pin sockets 22 and the conductive pins 12 can form a tight structural fit to ensure stable electrical connection. It is understood that the aforementioned combing device 2 includes hair straighteners, curling combs, and flat iron combs, etc., and correspondingly, different combing devices 2 are equipped with corresponding functional components, which are typically heating modules.

[0036] Furthermore, to ensure the plug 21 fits into the slot and facilitates the assembly of the comb device 2 and the handle 1, the outer edge of the plug 21 is provided with a cut surface, and a guide block is provided inside the slot. When the guide block aligns with the cut surface, the plug 21 can be inserted into the slot axially, allowing several conductive pins 12 to align and be inserted into the pin seat 22. Of course, the cross-sections of the slot and the plug 21 can be non-circular, which can also ensure accurate matching between the conductive pins 12 and the pin seat 22.

[0037] The needle holder 22 is a hollow tube with an open end facing the insertion structure. Several conductive flaps 25 are provided on the open end of the needle holder 22, spaced at equal angles around the inner hole of the needle holder 22. Preferably, the conductive flaps 25 at the open end of the needle holder 22 allow the conductive needle 12 to contact and connect with the conductive flaps 25 after insertion into the needle holder 22. The conductive flaps 25 can better cover and fit the conductive needle 12, thus ensuring the stability of the electrical connection. It is understood that the needle holder 22 and the conductive flaps 25 are integrally stamped, and the tail end of the needle holder 22 is tapered for easy welding.

The plug 21 has a positioning hole 26, and the pin 16 is movably inserted through the locking hole 31. When the plug 21 is inserted into the slot, the lower end of the pin 16 can be inserted into the positioning hole 26. The support frame 3 is used to install the locking structure. The outer diameter of the support frame 3 is larger than that of the socket 11 and has a certain thickness, thus forming the locking hole 31 to install the pin 16, allowing the pin 16 to move a certain distance along the locking hole 31. It can be understood that the direction of movement of the pin 16 is perpendicular to the insertion direction of the plug 21, or the pin 16 is arranged radially along the handle 1. Further, when the plug 21 is inserted into the slot of the socket 11 along the axial direction of the handle 1, the positioning hole 26 and the locking hole 31 are opposite each other, allowing the pin 16 to be inserted into the positioning hole 26, thereby locking the plug 21 inside the socket 11.

[0039] The locking structure also includes a knob ring 32 and a spring pin bracket 33. A positioning seat 34 is provided on the keel 3, and a lock hole 31 is formed on the positioning seat 34. The spring pin bracket 33 is mounted on the positioning seat 34 and slidably connected thereto. The pin 16 is mounted on the spring pin bracket 33, and a spring 35 is provided between the spring pin bracket 33 and the positioning seat 34. The knob ring 32 is rotatably fitted onto the keel 3, and the upper end of the pin 16 abuts against the inner wall of the knob ring 32.

In the normal state, the upper end of the pin 16 corresponds to the relief groove 36, causing the lower end of the pin 16 to retract into the lock hole 31. At this time, the plug 21 can be inserted into or removed from the socket 11. Rotating the knob ring 32 pushes the pin 16 through its inner wall, causing the lower end of the pin 16 to insert into the positioning hole 26, thereby fixing the comb device 2 to the handle 1.
