Description

Technical Field

[0001] This utility model relates to the field of hair styling appliance technology, and in particular to a quick-connect structure for a hot air comb. Background Technology

[0002] Traditional hot air combs typically use fixed plugs or threaded connections for power, which can lead to problems such as inconvenience in plugging and unplugging, loosening, and poor contact. Furthermore, the existing plug-to-power cord connection is usually non-rotatable, which can cause the cord to twist and break over time.

[0003] The portable hair curler disclosed in Chinese Publication No. CN110444976B features a detachable power cord structure. It attempts to connect the device's tail sleeve to the rotating cord, using a spring-loaded coil and latch at the tail to achieve elastic locking and allow the cord to rotate. However, relying on this elastic locking mechanism requires pushing the tail spring to compress the spring, resulting in numerous steps and hindering rapid insertion and removal. Therefore, there is an urgent need for a quick-connect structure that combines rapid insertion and removal, stable locking, and rotatable anti-kink design. Utility Model Content

[0004] The purpose of this invention is to provide a quick-connect structure for a hot air comb that enables rapid insertion and removal, stable locking, and ensures good electrical connection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-connect structure for a hot air comb, applied to a hot air comb, comprising:

[0007] The socket 1 is located in the housing of the hot air comb. Inside it is a conductive post 11, the top of the conductive post 11 is provided with a slot 12, and the middle is provided with a positioning block 13.

[0008] The plug 2 is inserted into the socket 1 at one end and includes a housing 21. The upper half of the housing 21 is provided with a buckle assembly 211, and the front end of the lower half is provided with a connector 212 that is inserted into the conductive post 11. The interior is provided with a conductive component 22 that is connected to the connector 212.

[0009] The snap-fit ​​assembly 211 and the slot 12 form a separable locking engagement to ensure a stable connection between the plug 2 and the socket 1.

[0010] Furthermore, the latch assembly 211 includes a button 211a, a latch 211b, a hinge 211c, and a return spring 211d. Pressing the button 211a can release the lock, making it easy to quickly unplug the plug 2.

[0011] Furthermore, the connector 212 includes a first insert body 212a and a second insert body 212b, with a positioning slot 212c between them, which cooperates with the positioning block 13 to achieve guided insertion and prevent reverse insertion.

[0012] Furthermore, the conductive element 22 includes a first conductive sheet 221 and a second conductive sheet 222, which respectively form a stable electrical connection with the conductive post 11, and slide in contact with the conductive cylinders 31 and 32 of the power line 3 through elastic conductive petals 221b and 222b to ensure reliable conductivity.

[0013] Furthermore, the power line 3 adopts a coaxial dual conductive cylinder design, with the first conductive cylinder 31 nested inside the second conductive cylinder 32, and an insulating surface 33 provided between them to prevent short circuits.

[0014] Furthermore, the housing 21 is provided with an annular groove 23 at one end near the power cord 3, which cooperates with the retaining ring 34 of the second conductive cylinder 32 to achieve axial limiting and rotation functions, thereby preventing the power cord from getting tangled.

[0015] Furthermore, the outer side of the housing 21 is covered with an anti-slip rubber sleeve 24, and an inclined block 25 is provided to reinforce the fixation of the anti-slip rubber sleeve 24, thereby improving the grip comfort.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. Quick Insertion and Removal: Utilizing a one-button latch assembly that engages with the connector's slot, simply press the button to easily remove the plug, making operation convenient. A return spring provides stable elasticity, ensuring the latch remains firmly engaged with the slot, preventing accidental loosening during use.

[0018] 2. Anti-misinsertion: The conductive component uses elastic conductive flaps to form a sliding contact with the conductive cylinder of the power cord, ensuring good conductivity even after long-term use. The conductive tube and conductive post adopt a tight insertion structure to reduce contact resistance and avoid overheating issues.

[0019] This design is particularly suitable for nighttime or blind operation scenarios, enhancing safety during use.

[0020] 3. Stable conductivity: The sliding contact between the elastic conductive petals and the conductive cylinder ensures the stability of conductivity during long-term use.

[0021] 4. Anti-tangling: The rotating engagement structure of the retaining ring and the retaining groove allows the power cord to rotate freely 360°, avoiding breakage of internal wires due to frequent twisting.

[0022] This design is particularly suitable for high-frequency use scenarios such as hair salons, reducing the risk of cable damage.

[0023] 5. Anti-slip and durable: The outer shell is covered with an anti-slip rubber sleeve, enhancing grip comfort and ensuring stable operation even with wet hands. The interlocking structure between the inclined block and the inner cavity of the anti-slip rubber sleeve prevents the sleeve from shifting or falling off, improving product durability.

[0027] Figure 4 This is a cross-sectional view of the plug of this utility model; Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] The plug 2 is pre-aligned with the socket 1, and the positioning slot 212c of the connector 212 and the positioning block 13 of the socket 1 are used for insertion guidance. During axial insertion, the conductive post 11 enters the guide hole of the connector 212, and at the same time, the latch 211b of the latch assembly 211 is inserted into the slot 12 of the conductive post 11 under the action of the return spring 211d, forming a mechanical lock. When the button 211a is pressed, the latch 211b rotates around the hinge 211c and disengages from the slot 12, so that the plug 2 can be quickly pulled out.

[0030] The first conductive piece 221 and the second conductive piece 222 of the internal conductive component 22 of the plug 2 are respectively connected to the conductive post 11 through the first conductive tube 221a and the second conductive tube 222a. The first conductive cylinder 31 and the second conductive cylinder 32 at the end of the power cord 3 are inserted into the plug 2, and the first elastic conductive petal 221b and the second elastic conductive petal 222b respectively clamp the outer circumference of the conductive cylinder, forming a conductive path of circumferential rotational sliding contact. The circumferential rotation refers to a continuous 360° rotation around the central axis.

[0031] The power cord 3 has a retaining ring 34 on the outer circumference of the second conductive cylinder 32. The annular groove 23 in the inner cavity of the plug housing 21 provides axial restraint for the retaining ring 34. When the power cord 3 rotates, the retaining ring 34 rotates circumferentially along the annular groove 23, while the first conductive cylinder 31 and the second conductive cylinder 32 slide within the elastic conductive petals 221b and 222b to prevent the cord from twisting.

[0032] The plug housing 21 is covered with an anti-slip rubber sleeve 24. The inclined block 25 at the bottom of the housing 21 is engaged and fixed with the inner cavity of the anti-slip rubber sleeve 24 to ensure grip stability. The button 211a is exposed outside the anti-slip rubber sleeve 24 for easy one-handed operation.

[0033] Operating procedure instructions:

[0034] Plug-in: Align plug 2 with socket 1, insert axially until latch 211b locks in place, and conductive tubes 221a and 222a are in full contact with conductive post 11;

[0035] Rotation: The power cord 3 can rotate freely, the retaining ring 34 rotates in the annular groove 23, and the elastic conductive petals 221b and 222b maintain a stable electrical connection.

[0036] Separation: Press button 211a to release latch 211b from locking, and pull out plug 2 axially.

[0037] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
