Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a neutral electrode connector and a desktop radio frequency skin therapeutic device. Background Art

[0002] The neutral electrode of the desktop radio frequency skin therapy device is connected to the return end of the radio frequency line of the pipeline through a connector. The connector includes a shell, a cover and a terminal. The shell and the cover are detachably connected and enclosed to form a wire passage for the pipeline to pass through. The shell is provided with a through hole passing through in the front-to-back direction. The inner end of the terminal passes through the through hole and is fastened by a fastening nut. The return end of the radio frequency line is connected to the inner end of the terminal, and the wire of the neutral electrode is connected to the outer end of the terminal.

[0003] Since the inner cavity of the shell is relatively small and the terminal extends roughly along the front-to-back direction of the shell, it is very troublesome, time-consuming and laborious to rotate the locking nut. In the related art, the locking nut is directly welded to the inner end of the terminal. This makes the terminal difficult to assemble, cannot be disassembled and has poor reliability. In addition, the shell is easily damaged during welding. In addition, during use, it is easy for the connection between the terminal and the neutral electrode wire to become unstable, affecting conductivity. In the related art, the solution is to set two wires for the neutral electrode, set two terminal blocks, and add a return end to form two return ends. The two wires of the neutral electrode are connected to the two return ends respectively through the two terminal blocks. However, since a return end needs to be added, not only is the operation more troublesome, but the cost is also increased. Summary of the Invention

DETAILED DESCRIPTION

[0019] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0020] Reference below Figures 1 to 9 A neutral electrode connector and a desktop radio frequency skin treatment device according to embodiments of the present invention are described.

[0021] refer to Figure 4 、 Figure 5 、 Figure 8 and Figure 9 As shown, the neutral electrode connector 10 according to the embodiment of the first aspect of the present invention is applied to a desktop radio frequency skin therapy device. The desktop radio frequency skin therapy device includes a device body 40. The device body 40 can be connected to a pipeline 30. The end of the pipeline 30 can be connected to a radio frequency handle 50. The pipeline 30 may include a sleeve and a radio frequency wire, a water pipe, etc. arranged in the sleeve. The radio frequency wire has a radio frequency end and a return end 600. The radio frequency end of the radio frequency wire is connected to the radio frequency electrode on the radio frequency handle 50. The neutral electrode connector 10 of the present invention is used to connect the two connecting wires 500 of the neutral electrode 20 to the return end 600 of the radio frequency wire.

[0022] When performing skin treatment, the RF electrode on the RF handle 50 can contact the skin of the treatment area of ​​the human body, and the neutral electrode 20 can be attached to the skin of other areas of the human body, such as the skin on the back of the neck. The RF current generated by the RF electrode enters the human skin and then returns to the return end 600 of the RF line through the neutral electrode 20 to form a closed loop. When the RF current enters the human skin, it will act on the human tissue to produce a thermal effect, thereby playing a cosmetic treatment effect, so as to achieve the effect of treating skin sagging, reducing skin wrinkles, and tightening the skin. The neutral electrode 20 can be set to a sheet structure with a large contact area with the human skin, so that when the RF current enters the neutral electrode 20 from the human body, it can avoid the RF current being too concentrated, causing discomfort or even burns to the skin.

[0023] refer to Figures 1 to 8 As shown, the neutral electrode connector 10 includes a housing 100 , a cover 200 , a wiring structure 300 and two fasteners 400 .

[0024] The housing 100 is formed with a first cavity 101, which is open at the top. Two mounting holes 102 extending in the vertical direction are provided in the first cavity 101. For example, two mounting portions may be provided at the bottom of the first cavity 101, and the two mounting holes 102 may be provided in the two mounting portions, respectively. The extending direction of the mounting holes 102 may be perpendicular to the plane of the opening area at the top of the housing 100. The side wall of the housing 100 is provided with two through holes 103 extending in the front-to-back direction. For example, the two through holes 103 may both be provided in the front wall of the housing 100, or both be provided in the rear wall of the housing 100. The through holes 103 connect the first cavity 101 with the outside of the housing 100, and the penetration direction of the through holes 103 may be parallel to the plane of the opening area at the top of the housing 100.

[0025] The cover body 200 is detachably connected to the top of the shell 100, for example, it can be connected by bolt connection, clamping or other suitable methods. The cover body 200 covers the opening area at the top of the shell 100, and the cover body 200 forms a second cavity 201. The first cavity 101 of the shell 100 and the second cavity 201 of the cover body 200 are enclosed to form a wire passage for the pipeline 30 to pass through.

[0026] The wiring structure 300 includes two longitudinal members 301 and a transverse member 302. The two ends of the transverse member 302 are respectively connected to the two longitudinal members 301. For example, the transverse member 302 and the two longitudinal members 301 can be integrally formed or welded. The two longitudinal members 301 are respectively inserted into the two through holes 103. The inner ends of the two longitudinal members 301 are both located in the first cavity 101. The inner ends of the two longitudinal members 301 can be provided with connection holes 305. The inner end of one of the longitudinal members 301 is used to connect to the return end 600 of the radio frequency line. The outer ends of the two longitudinal members 301 are located outside the shell 100 and are respectively used to connect to the two connecting wires 500 of the neutral electrode 20. Since the two longitudinal members 301 are connected together by the transverse member 302, the return end 600 can be electrically conductive with both longitudinal members 301, and thus can be electrically conductive with both connecting wires 500. The wiring structure 300 is made of a conductive material, preferably bare copper.

[0027] The two fasteners 400 are respectively inserted through the connection holes 305 at the inner ends of the two longitudinal members 301 and installed in the two mounting holes 102 to cooperate with the housing 100 to clamp and secure the inner ends of the two longitudinal members 301. Because the mounting holes 102 extend in the vertical direction, the fasteners 400 installed in the mounting holes 102 also extend generally in the vertical direction, so that the axial direction of the fasteners 400 is generally toward the opening at the top end of the housing 100.

[0028] An incision is provided on the sleeve of the pipeline 30, and the return end 600 of the radio frequency line is passed through the incision and pulled out of the sleeve. The two longitudinal members 301 of the wiring structure 300 are respectively passed through the two through holes 103, and then the two fasteners 400 are respectively passed through the inner ends of the two longitudinal members 301 and installed in the two mounting holes 102. The two fasteners 400 can cooperate with the shell 100 to clamp and fix the inner ends of the two longitudinal members 301 respectively. Then, the return end 600 of the radio frequency line of the pipeline 30 is connected to the inner end of one of the longitudinal members 301, and the two connecting wires 500 connected to the neutral electrode 20 are respectively connected to the outer ends of the two longitudinal members 301. Finally, the shell 100 is connected to the cover body 200.

[0029] According to the neutral electrode connector 10 of the embodiment of the present invention, since the mounting hole 102 extends in the up-down direction, the axial direction of the fastener 400 is roughly toward the opening at the top of the shell 100. This makes it convenient for the staff to operate a screwdriver or other tools at the opening at the top of the shell 100 to install the fastener 400. At the same time, the through hole 103 penetrates in the front-to-back direction, so that the longitudinal member 301 of the wiring structure 300 extends correspondingly in the front-to-back direction, thereby facilitating the fastener 400 to be inserted into the inner end of the longitudinal member 301, thereby making the wiring structure 300 more convenient to assemble, and no welding construction is required during the installation process, thereby preventing damage to the shell 100. Since a transverse member 302 is provided between the two longitudinal members 301, only one return end 600 needs to be provided. The return end 600 is connected to the inner end of one of the longitudinal members 301, so that the return end 600 and the two longitudinal members 301 are both conductive, thereby achieving conductivity of the two connecting wires 500 with the neutral electrode 20 without the need for an additional return end 600, which is more convenient to operate. At the same time, two longitudinal members 301 are provided. Even if one of them has an unstable connection with the connecting wire 500 of the neutral electrode 20, it can still be normally conductive through the other longitudinal member 301, thereby making the conductivity between the radio frequency line and the neutral electrode 20 more stable and reliable.

[0030] It should be noted that the descriptions of the orientation or positional relationships such as up and down, front and back, and left and right mentioned in the present invention are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the contents of the present invention, rather than indicating or implying that the corresponding components must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention. refer to Figure 1 、 Figure 2 、 Figures 5 to 7 As shown, in some embodiments of the present invention, the fastener 400 is configured as a screw, and the mounting hole 102 is configured as a threaded hole. In this embodiment, when it is necessary to secure the inner end of the longitudinal member 301, the screw portion of the fastener 400 is inserted through the inner end of the longitudinal member 301 and threadedly connected to the mounting hole 102, which is configured as a threaded hole. The head of the fastener 400 and the housing 100 can then cooperate to clamp the inner end of the longitudinal member 301. This not only simplifies the structure and is easy to operate, but also provides a more stable clamping and fixing of the longitudinal member 301.

[0031] It should be noted that in some other embodiments of the present invention, the fastener 400 may also be other structures, for example, it may also be a bolt. In this case, the mounting hole 102 does not need to be set as a threaded hole, but only needs to be passed through at both ends. The bolt is sequentially passed through the inner end of the longitudinal member 301 and the mounting hole 102 and then the nut is installed.

[0032] refer to Figure 1 and Figure 6As shown, in some embodiments of the present invention, the housing 100 is provided with two hot-melt nuts 104, and the threaded holes of the hot-melt nuts 104 form the mounting holes 102. For example, the housing 100 and the two hot-melt nuts 104 can be integrally formed using a plastic injection molding process. Compared to directly machining the mounting holes 102 in the form of spiral holes on the housing 100, in this embodiment, the mounting holes 102 are formed by the hot-melt nuts 104 made of a metal material. This is not only convenient to manufacture, but also reduces wear on the internal threads of the mounting holes 102 during long-term use, thereby extending the service life.

[0033] It should be noted that, in some other embodiments of the present invention, the mounting hole 102 may also be directly processed on the housing 100 , which will not be described in detail here.

[0034] refer to Figure 1 、 Figure 2 、 Figures 5 to 7 As shown, in some embodiments of the present invention, the longitudinal member 301 includes a blocking portion 303 and a terminal lug 304. The blocking portion 303 is used to block the through-hole 303. The terminal lug 304 is connected to the inner end of the blocking portion 303. The terminal lug 304 is provided with a connecting hole 305 extending through the thickness of the blocking portion 303, and the fastener 400 is inserted through the connecting hole 305. For example, the outer peripheral wall of the blocking portion 303 can be adapted to at least a portion of the hole wall of the through-hole 103. The terminal lug 304 is a sheet-like structure. The thickness direction of the terminal lug 304 can be the vertical direction. The connecting hole 305 extends through the vertical direction. The thickness dimension of the terminal lug 304 can be smaller than the vertical dimension of the blocking portion 303.

[0035] In this embodiment, a blocking portion 303 is provided to block the through hole 103, thereby preventing external water and dust from entering the connector. A terminal piece 304 is provided, and the fastener 400 is inserted through the connection hole 305 of the terminal piece 304 and then installed in the installation hole 102. This makes the installation of the longitudinal member 301 more stable. Moreover, the connection hole 305 penetrates along the thickness direction of the terminal piece 304. When the return end 600 is clamped between the head of the fastener 400 and the housing 100, the end face of the terminal piece 304 in the thickness direction can be attached to the return end 600. In this way, the longitudinal member 301 and the return end 600 of the RF line are in closer contact, and the conductive stability is improved.

[0036] refer to Figure 1 、 Figure 2 and Figure 5As shown, in some embodiments of the present invention, a horizontal member 302 is positioned within the first cavity 101, with its ends connected to two connecting lugs 304. Two first spacers 105 are positioned within the first cavity 101, with the top surfaces of the first spacers 105 higher than the mounting holes 102. The top surfaces of the two first spacers 105 abut against the bottom surfaces of the two connecting lugs 304. When installing the wiring structure 300, the wiring structure 300 is first positioned within the first cavity 101, with the two longitudinal members 301 aligned with the two through-holes 103. The wiring structure 300 is then moved from the inside out, so that the blocking portions 303 of the two longitudinal members 301 of the wiring structure 300 are inserted into the two through-holes 103. The thickness of the terminal piece 304 is generally smaller than the size of the sealing portion 303 in the up and down directions. In order to prevent the terminal piece 304 from being in a suspended state and causing the wiring structure 300 to be installed unstable, in this embodiment, two first pads 105 are provided. The top surface of the first pad 105 is higher than the mounting hole 102. The top surfaces of the two first pads 105 are respectively in contact with the bottom surfaces of the two terminal pieces 304, thereby supporting the terminal piece 304, thereby making the wiring structure 300 more stable.

[0037] refer to Figures 1 to 3 as well as Figures 5 to 7 As shown, in some embodiments of the present invention, a first connection portion 106 is provided in the first cavity 101, and a second connection portion 202 is provided in the second cavity 201. The first connection portion 106 and the second connection portion 202 are detachably connected, and two mounting holes 102 are respectively located on either side of the first connection portion 106. For example, two first connection portions 106 can be provided and arranged in the front-to-back direction in the first cavity 101, and two second connection portions 202 can be provided and arranged in the front-to-back direction in the second cavity 201. The two second connection portions 202 can correspond one-to-one with the two first connection portions 106. The first connection portion 106 and the corresponding second connection portion 202 can be connected by bolts or snap-fit. In this way, the connection between the housing 100 and the cover 200 is more convenient and stable. The two mounting holes 102 can be respectively located on either side of the first connection portion 106 on the front side of the housing 100, with the mounting holes 102 close to the first connection portion 106, making the structure more compact and reliable.

[0038] refer to Figure 1 、 Figure 2 and Figure 5As shown, in some embodiments of the present invention, when the cross member 302 is located in the first cavity 101, the sidewall of the cross member 302 abuts against the sidewall of the first connecting portion 106. A second cushion block 107 is provided in the first cavity 101. The top surface of the second cushion block 107 is at the same height as the top surface of the first cushion block 105, and the top surface of the second cushion block 107 abuts against the bottom surface of the cross member 302. For example, when the through hole 103 is provided in the front sidewall of the housing 100, the front sidewall of the cross member 302 may abut against the rear sidewall of the first connecting portion 106 on the front side of the housing 100.

[0039] In this embodiment, the limiting function of the first connecting portion 106 reduces the possibility of random movement of the wiring structure 300, providing a more secure installation. Furthermore, when the sidewall of the transverse member 302 abuts the sidewall of the first connecting portion 106, the connection hole 305 of the wiring lug 304 is aligned with the mounting hole 102, allowing for quick positioning of the wiring structure 300 and facilitating installation of the fastener 400. A second spacer 107 is provided, the top surface of which is flush with the top surface of the first spacer 105. The top surface of the second spacer 107 abuts the bottom surface of the transverse member 302, thereby supporting the transverse member 302 and providing a more secure installation of the wiring structure 300.

[0040] It should be noted that the side wall of the first connecting portion 106 for abutting against the transverse member 302 can be set to be a plane to achieve a better abutting effect.

[0041] refer to Figures 6 to 8 As shown, in some embodiments of the present invention, the horizontal member 302 is located outside the housing 100, and the ends of the horizontal member 302 are respectively connected to the two blocking portions 303. When installing the wiring structure 300, the wiring structure 300 is first positioned outside the housing 100 and the two vertical members 301 are aligned with the two through-holes 103. Then, the wiring structure 300 is moved from the outside to the inside so that the blocking portions 303 of the two vertical members 301 of the wiring structure 300 are respectively inserted into the two through-holes 103, making installation more convenient.

[0042] refer to Figure 6 As shown, in some embodiments of the present invention, through-hole 103 includes a countersunk section 109 and an insertion section 110. Countersunk section 109 is disposed on the outer surface of housing 100, and insertion section 110 is disposed on the inner end surface of countersunk section 109. A terminal lug 304 is inserted through insertion section 110, and a sealing portion 303 is inserted into countersunk section 109. In this embodiment, after terminal lug 304 of longitudinal member 301 is inserted through insertion section 110, sealing portion 303 of longitudinal member 301 is inserted into countersunk section 109, thereby sealing insertion section 110 and further preventing external water and dust from entering the connector. Furthermore, the wall of countersunk section 109 can be generally circular or have other shapes.

[0043] refer to Figure 5 As shown, in some embodiments of the present invention, the return end 600 is provided with a connecting ring 601, and the fastener 400 is used to pass through the connecting ring 601 to clamp and fix the connecting ring 601. In this embodiment, when the fastener 400 passes through the inner end of the longitudinal member 301 and is installed in the mounting hole 102, the fastener 400 is also passed through the connecting ring 601. The connecting ring 601 is clamped between the longitudinal member 301 and the head of the fastener 400 or between the longitudinal member 301 and the housing 100. In this way, the electrical connection between the return end 600 of the RF line and the longitudinal member 301 can be achieved, which is simple and convenient to operate and the connection is more stable.

[0044] Of course, in some other embodiments of the present invention, the return end 600 may also be connected to the inner end of the longitudinal member 301 in other ways. For example, the return end 600 may also be snap-fitted to the inner end of the longitudinal member 301 .

[0045] refer to Figure 1 、 Figure 2 、 Figures 5 to 7 As shown, in some embodiments of the present invention, a first buckle 306 is provided at the outer end of the longitudinal member 301, and a second buckle 501 is provided at the end of the connecting wire 500, with the first buckle 306 being configured to engage with the second buckle 501.

For example, multiple groups of first protrusions 108 can be provided in the first cavity 101, and the multiple groups of first protrusions 108 can be arranged in the left-right direction, and each group can include one or more first protrusions 108; multiple groups of second protrusions 203 can be provided in the second cavity 201, and the multiple groups of second protrusions 203 can be arranged in the left-right direction, and each group can include one or more second protrusions 203.

[0048] When the shell 100 is connected to the cover body 200 and the pipeline 30 is passed through, the multiple first protrusions 108 can abut the outer surface of one side of the sleeve of the pipeline 30, and the multiple second protrusions 203 can abut the outer surface of the other side of the sleeve of the pipeline 30. Through the friction between the first protrusions 108 and the sleeve, and the friction between the second protrusions 203 and the sleeve, the random rotation of the connector along the circumferential direction of the pipeline 30 can be reduced, and the random sliding of the connector along the length direction of the pipeline 30 can be reduced. Moreover, when the sleeve is a bellows, the first protrusion 108 and the second protrusion 203 can also be located between the two corrugations of the bellows. In this way, through the cooperation between the corrugations of the bellows and the first protrusion 108 or the second protrusion 203, the random sliding of the connector along the length direction of the pipeline 30 can be further prevented.

[0049] It should be noted that, in some other embodiments of the present invention, the plurality of first protrusions 108 may be provided only in the first cavity 101 , or the plurality of second protrusions 203 may be provided only in the second cavity 201 .
