[0002] Radiofrequency (RF) therapy devices are widely used in modern beauty and medical fields. RF technology generates a thermal effect through the action of high-frequency electromagnetic waves, stimulating the metabolism of deep skin tissues and promoting collagen remodeling and regeneration, thereby achieving effects such as skin tightening, wrinkle removal, and improved skin texture. In these devices, the handpiece is a crucial part for user operation; it needs to achieve a reliable electrical and fluid connection with the main unit to ensure stable transmission of high-frequency energy and effective water cooling.

[0003] Traditional radiofrequency therapy device handpiece connection mechanisms typically suffer from the following problems: First, the electrical signal and cooling water paths at the connection mechanism are often separated, making it impossible to simultaneously control electrical signals and monitor the water cooling system using the same connection mechanism. Second, traditional connectors have weak anti-interference capabilities, especially in high-frequency signal transmission, making them susceptible to external electromagnetic interference, leading to signal attenuation or even distortion. Third, connecting and disconnecting the handpiece from the main unit is complex, requiring screws or other fixing tools, which hinders rapid device replacement and maintenance. Finally, traditional designs lack effective protective measures, making the connection points susceptible to environmental factors such as dust and moisture, reducing the reliability and lifespan of the device.

[0035] Example 1

[0036] like Figure 1-4 As shown, this embodiment discloses a plug-in mechanism, including a connector 1 and a fixed connector base 2, which are detachably connected.

[0037] The fixed connector base 2 is provided with a high frequency path output terminal 201, a low frequency signal path output terminal 202 and a water path output port 203 respectively; the connector 1 is provided with a high frequency path receiving terminal 101, a low frequency signal path receiving terminal 102 and a water path input port 103.

[0038] The high-frequency path output terminal 201 is connected to the high-frequency path receiver terminal 101; the low-frequency signal path output terminal 202 and the low-frequency signal path receiver terminal 102 are connected in conjunction; the water path output port 203 is connected to the water path input port 103.

[0039] The fixed connector base 2 is provided with a fixing washer 204, which is fixed to the fixed connector base 2; the fixing method is screw or bolt locking connection.

[0040] The connector 1 is also provided with a terminal assembly fastener 104 that is adapted to and connected to the fixing gasket 204. The terminal assembly fastener 104 is locked onto the connector 1 by a nut.

[0041] This plug-in mechanism integrates high-frequency electrical paths, low-frequency signal paths, and water channels into a single interface. By cooperating with the connector 1 and the fixed connector base 2, it simplifies the connection complexity of the device, improves the convenience of operation and the integration of the system. This design reduces the hassle of needing multiple independent interfaces for connection and improves the efficiency of the device.

[0042] The fixing pad 204 is provided with a metal pin 2041 that is connected to the high frequency path; the terminal assembly fixing part 104 is provided with a metal pin groove 1041 that is adapted to and connected to the metal pin 2041; the number of metal pins can be set to one or more, depending on the component selection and matching relationship of the corresponding equipment.

[0043] The metal ejector pin 2041 and the metal ejector pin slot 1041 are each connected to a high-frequency path transmission module at their respective ends. The metal ejector pin 2041 and the high-frequency path output module together constitute the high-frequency path output terminal 201; the metal ejector pin slot 1041 and the high-frequency path receiving module together constitute the high-frequency path receiving terminal 101.

[0044] By providing a metal pin 2041 on the fixed connector base 2 and a metal pin slot 1041 on the connector 1, a stable path for high-frequency electrical signals can be ensured during connection. The precise fit between the metal pin 2041 and the metal pin slot 1041 helps reduce resistance and interference in electrical signal transmission, ensuring high-quality transmission of high-frequency electrical signals.

[0045] The materials for the fixed connector base 2 and connector 1 can be selected according to different conductivity and heat resistance materials according to application requirements. For example, the metal pin 2041 and the metal pin groove 2041 can be made of copper-plated gold material to improve the conductivity and corrosion resistance of signal transmission.

[0046] The connector 1 is equipped with a dustproof housing 105, and there are push-to-unlock buttons 106 on both sides of the dustproof housing; the surface of the push-to-unlock button 106 has raised strips to increase friction. The dustproof housing 105 is concave, and the tail end of the dustproof housing 105 is also equipped with a water and electricity connection pipe.

[0047] The mechanism uses a press-to-unlock button 106 to control the connection and disconnection operation. The press-to-unlock button 106 has a raised strip to increase friction, ensuring a comfortable feel and preventing slippage during operation. This design allows the operator to achieve connection or disconnection with a simple press operation, providing the ability to connect and disconnect quickly. At the same time, the fixing washer 204 and the terminal assembly fastener 104, which are locked by nuts, ensure the firmness and safety of the connection.

[0048] In addition to the raised strip design, an anti-slip rubber pad or surface texture can be added to the press-to-unlock button 106 to further improve the feel and friction during operation, especially in humid environments or when operating with gloves, which can improve the convenience of the operator's work and the versatility of the scenario.

[0049] The dustproof housing 105 effectively protects the internal connection terminals from dust and other impurities, while also helping to extend the service life of the equipment and reduce the probability of poor contact and failure caused by environmental factors.

[0050] Example 2

[0051] like Figure 1-4 As shown, this embodiment discloses another insertion and removal mechanism, which is similar to that of embodiment 1, except that:

[0052] The low-frequency signal path output terminal 202 is provided with a male signal connector plug 2021, and the low-frequency signal path receiving terminal 102 is provided with a female signal connector plug 1021.

[0053] The tail end of the male connector 2021 is connected to the low-frequency signal output module; the tail end of the female connector 1021 is connected to the low-frequency signal receiving module.

[0054] The male signal connector 2021 and the low-frequency signal output module together form the low-frequency signal path output terminal 202; the female signal connector 1021 and the low-frequency signal receiving module together form the low-frequency signal path receiving terminal 102. The male signal connector 2021 is a D-sub connector; the female signal connector 1021 is a D-sub connector, and the end of the D-sub receiver female connector is connected to a PCBA board for receiving low-frequency signals.

[0055] Example 3

[0056] like Figure 1-4 As shown, this embodiment discloses another plug-in mechanism, which is similar to that of embodiment 1, except that: the water passage outlet 203 of the fixed plug-in base 2 is provided with a CPC female interface 2031; the water passage inlet 103 of the plug 1 is provided with a CPC male connector 1031, and the CPC female interface 2031 and the CPC male connector 1031 are adapted to each other. One end of the CPC female interface 2031 is connected to the water tank supplying cooling water, and the other end is connected to the CPC male connector 1031. The end of the CPC male connector 1031 is connected to the cooling water delivery pipe.

[0057] The end of CPC male connector 1031 is connected to the water supply pipeline, and one end of CPC female connector 2031 is connected to the water supply tank, and the other end is connected to CPC male connector 1031.

[0058] The design employs a CPC female connector 2031 and a CPC male connector 1031 to ensure a stable water circuit connection. The CPC connector is renowned for its excellent sealing performance and durability, effectively preventing cooling water leakage. Reliable cooling water transmission is crucial for the operation of radiofrequency therapy, especially in high-frequency radiofrequency applications. The use of cooling water effectively reduces physiological discomfort caused by overheating in the treated patient, ensuring a synchronous supply of cooling water during radiofrequency therapy. During the selection process, a CPC connector equipped with a water flow sensor can be chosen based on the performance of the host machine and the control system. This allows for control of the cooling water output according to the specific treatment plan during operation, improving treatment effectiveness.

[0059] The connector 1 has a dustproof housing 105, and push-to-unlock buttons 106 are provided on both sides of the dustproof housing 105. The dustproof housing 105 is connected to the fixed connector base 2 by a snap-fit, and the push-to-unlock buttons 106 are connected to the snap-fit. The surface of the push-to-unlock buttons 106 has raised strips to increase friction. The dustproof housing 105 is concave and also has water and electricity connection pipes.

[0060] The CPC female interface 2031 is provided with a press-to-unlock mechanism 205 and a locking pin 206 on the interface surface;

[0061] The press-to-unlock mechanism 205 includes a metal buckle 2051. The buckle groove of the metal buckle 2051 is locked to the locking pin 206 on the interface surface of the CPC female interface 2031. One end of the metal buckle 2051 is connected to a pressure end 2052 and a return spring. One end of the return spring is connected to the metal buckle 2051, and the other end is connected to the CPC female interface 2031. The pressure end 2052 is fixed on the metal buckle 2051.

[0062] By applying external force to press the end face of the pressure end 2052, the pressure end 2052 presses the return spring, thereby pushing the metal buckle 2051 to move and locking the pin 206 away from the buckle groove of the metal buckle 2051.

[0063] The combination of the locking pin 206 and the metal clip 2051 provides a dual locking function, ensuring the firmness of the connection and preventing failure under high-intensity use. If the user forcibly pulls out the connector 1 without pressing the unlock button 106 at both ends of the dustproof housing 105 after locking the connector 1 and the fixed connector base 2, the relative position between the locking pin 206 and the metal clip 2051 will not move, thus locking the connector structure and improving the overall safety and reliability of the equipment. The press-to-unlock mechanism 205 applies external force to the press-to-unlock button 106. This external force is further applied to the pressure end 2052 via the press-to-unlock button 106. When the pressure end 2052 is subjected to external force, it compresses the return spring, forcing the metal latch 2051 to move in the direction of the applied force. At this time, the locking pin 206 retracts, and the metal latch 2051 continues to move in the direction of the applied force. The locking pin 206 is then lifted, and the insertion / removal mechanism completes the unlocking process. The connector 1 and the fixed connector base 2 are in the unlocked state. The entire operation process simplifies the user's operation, especially in emergency situations, allowing the user to quickly disconnect the connection and improving work efficiency.
