[0003] There are certain problems with existing introduction instruments: 1. Current introduction instruments are generally single-headed, and have poor skin adhesion during use, resulting in poor introduction effect; 2. Introduction instruments generally need to be used in conjunction with a membrane cloth, which carries effective ingredients and is introduced through the membrane cloth. However, when used, the membrane cloth needs to be attached to the skin first, and then introduced through the introduction instrument. During the introduction process, the membrane cloth may shift; 3. Current introduction instruments have a single function and can only perform a single introduction method, which cannot meet the user's various skin care / treatment needs. Introduction instruments equipped with multiple different functions are expensive and inconvenient to carry. Summary of the Invention

[0040] like Figure 1-6As shown, this embodiment provides a multi-head introduction instrument, which includes a handle 1, an introduction component 2 and a membrane cloth component 3. The handle 1 can be provided with components such as buttons 17 and a display screen 18 to facilitate operation and viewing. The handle 1 is preferably designed to be curved to facilitate human hand holding. The introduction component 2 includes a base 21, one end of which is detachably mounted on the handle 1. The detachable method can be optional but not limited to a snap-on or magnetic connection. The other end of the base 21 is circumferentially spaced with multiple working heads 22. Each working head 22 is flexibly mounted on the base 21 and is preferably evenly spaced. The membrane cloth assembly 3 includes a membrane cloth 31 and a carrier 32. The membrane cloth 31 can be welded or bonded to the carrier 32 to form a whole. The membrane cloth 31 is detachably mounted on the base 21 with the aid of the carrier 32. The detachable method may be optional but not limited to snap-on or magnetic connection. After installation, the membrane cloth 31 covers the working surface of each working head 22, so that each working head 22 can be introduced through the membrane cloth 31.

[0041] Thus, the multi-head introduction instrument provided in this embodiment has an introduction component 2 that includes multiple working heads 22, and the multiple working heads 22 are flexibly installed, so that when in use, each working head 22 can better fit the skin for introduction, and the introduction effect is good; moreover, the membrane cloth component 3 is directly installed on the introduction component 2 for use, and the membrane cloth 31 is always fixed to the introduction component 2 during the introduction process, and there will be no problem of displacement; in addition, the introduction component 2 and the handle 1 are detachably connected, and different introduction components 2 can be replaced and installed on the handle 1 for use, and each introduction component 2 can correspond to a different introduction function, so that the function of the introduction instrument can be expanded, and compared with being equipped with multiple introduction instruments, the overall volume is smaller and easy to carry.

[0042] like Figure 3-4 As shown in Figures 8 and 8, the introduction component 2 and the handle 1 of this embodiment are connected by a snap-fit method. Specifically, a plug-in column 211 is provided at one end of the base 21 in the introduction component 2, and a corresponding plug-in slot 11 is provided on the handle 1. The inner side wall of the plug-in slot 11 is also symmetrically provided with two retaining springs 12. The outer side wall of the plug-in column 211 is provided with two retaining grooves 2111 at a certain distance from the end face. When the introduction component 2 and the handle 1 are installed, the plug-in column 211 of the base 21 is inserted into the plug-in slot 11, and the retaining spring 12 in the plug-in slot 11 is deformed under stress, avoiding the end face of the plug-in column 211, and then snapped into the retaining groove 2111 on the side wall of the plug-in column 211 to connect the two. When the introduction component 2 and the handle 1 need to be disassembled, the introduction component 2 is pulled out, and the retaining spring 12 is deformed under stress, avoiding the end face of the plug-in column 211, and then returns to its original state after the introduction component 2 is pulled out. If necessary, an anti-fool structure can also be provided to prevent reverse insertion. Of course, in other embodiments, a magnetic connection structure may also be used, for example, magnetic components are respectively provided on the base 21 and the handle 1 .

[0043] Furthermore, in this embodiment, a first electrical connection component 212 is provided on the end face of the plug-in column 211 of the base body 21, and the first electrical connection component 212 includes a first power electrical connector 2121 and a first signal electrical connector 2122. A second electrical connection component 13 is provided on the bottom surface of the plug-in slot 11 of the handle 1, and the second electrical connection component 13 includes a second power electrical connector 131 and a second signal electrical connector 132. In this way, power transmission, i.e., electric energy transmission, between the introduction component 2 and the handle 1 can be achieved by docking the first power electrical connector 2121 with the second power electrical connector 131, for example, providing the electric energy required by each working head 22; signal transmission between the introduction component 2 and the handle 1 can be achieved by docking the first signal electrical connector 2122 with the second signal electrical connector 132, for example, controlling and providing feedback to each working head 22.

[0044] like Figure 12 As shown, a main controller 14 and a battery 15 are also provided in the handle 1. The battery 15 is connected to the main controller 14 and the second power electrical connector 131 in the handle 1 via a cable in the handle 1, and can supply power to the main controller 14. It can also supply power to the first power electrical connector 2121 via the second power electrical connector 131. The main controller 14 is connected to the second signal electrical connector 132 in the handle 1 via a cable in the handle 1, and can supply power and transmit signals to the first signal electrical connector 2122. This embodiment also has a charging port 16 on the handle 1. In this embodiment, the battery 15 is provided in the handle 1, which reduces the volume and cost of the import assembly 2 compared to providing the battery 15 in the import assembly 2.

[0045] A drive module 213 and a sub-controller 214 are also provided in the base 21 of the introduction component 2. The drive module 213 is connected to the first power electrical connector 2121 and multiple working heads 22 through cables in the base 21. The drive module 213 is a voltage conversion circuit that matches the working head 22, which converts the voltage provided by the battery 15 into the working voltage required by the corresponding working head 22. For the same introduction component 2, its multiple working heads 22 are the same, but the working heads 22 of different introduction components 2 are different and can have different functions such as current, ultrasound, heating, ion, etc., so their working voltages will also be different. In this embodiment, a corresponding drive module 213 is provided in the base 21. When the drive module 213 is closed and working, each working head 22 can be powered and work. The sub-controller 214 is connected to the first signal electrical connector 2122 and the drive module 213 through cables in the base 21, that is, the sub-controller 214 can control the circuit on and off of the drive module 213 and can communicate with the main controller 14 in the handle 1. Thus, in this embodiment, a sub-controller 214 is provided in the import component 2 , and the drive module 213 can be controlled by the sub-controller 214 . In addition, the functions of the import component 2 can be conveniently increased by the sub-controller 214 .

[0046] Specifically, in this embodiment, a sensing element 33 is provided on the carrier 32, and an identification module 215 is correspondingly provided on the base body 21. The identification module 215 is electrically connected to the sub-controller 214 through a cable in the base body 21. The sensing element 33 and the identification module 215 can be optional but not limited to electronic tags and readers, so that it can be determined whether the membrane cloth component 3 is installed on the import component 2, and the information stored in the membrane cloth component 3 can be identified. When the membrane cloth assembly 3 is installed, the sensing element 33 enters the magnetic field range of the reader, obtains the induced current and sends the stored internal information. The reader in the base body 21 can read and identify this information, which is the type information of the current membrane cloth 31. Specifically, different membrane cloths 31 contain different functional substances, and different functional substances have different corresponding optimal introduction methods. For example, functional substances with small molecular weight can be introduced by ion introduction, while functional substances with large molecular weight need to be introduced into the deep layer of the skin through electroporation and other methods. Therefore, the membrane cloth assembly 3 in this embodiment is also set to correspond to the introduction assembly 2. In this way, the drive module 213 can be controlled to work after it is identified that the membrane cloth assembly 3 is compatible with the introduction assembly 2, avoiding incorrect selection and waste of the membrane cloth assembly 3; when the membrane cloth assembly 3 is not installed, the sub-controller 214 cannot recognize the sensing element 33. At this time, the drive module 213 can be controlled not to work and a prompt can be given.

[0047] like Figure 5-9As shown, the membrane cloth 31 in this embodiment is located on the side of the carrier 32 away from the seat body 21, and a through hole 321 is provided on the carrier 32 corresponding to each working head 22, so that each working head 22 can be attached to the membrane cloth 31 for introduction work. The membrane cloth 31 is preferably a dry membrane cloth, for example, formed by drying, freeze-drying, etc., which can prevent bacteria from growing during storage and has a longer storage time. The membrane cloth 31 can be moistened when needed. In this embodiment, a liquid outlet module 34 is provided on the side of the carrier 32 facing the seat body 21. The liquid outlet module 34 includes a accommodating chamber 341, a diversion channel 342, a liquid storage bag 343 and a puncture body 344. The accommodating chamber 341 is formed in the middle of the carrier 32 and close to one side of the introduction component 2. The diversion channel 342 is located on the bottom surface of the accommodating chamber 341, that is, the middle of the carrier 32, and can divert the liquid in the accommodating chamber 341 to the membrane cloth 31 on the other side. A liquid storage bag 343 is also placed in the accommodating chamber 341, and the liquid storage bag 343 can store pure water. The puncture body 344 is provided with a puncture tip 3441 at one end facing the liquid storage bag 343, and the puncture body 344 is slidably sealed at the opening of the accommodating cavity 341 close to the seat body 21 side with the help of a sealing ring. In the initial state, the puncture body 344 is fixed to the accommodating cavity 341, for example, by gluing or welding a tiny connecting strip. When in use, the puncture body 344 can be pushed toward the liquid storage bag 343 to puncture the liquid storage bag 343, and the liquid in the liquid storage bag 343 flows through the diversion channel 342 to the membrane cloth 31 to moisten it.

[0048] Preferably, if Figure 7 The diversion channel 342 includes a plurality of intermediate diversion holes 3421 penetrating the bottom surface of the accommodating cavity 341 and a plurality of diversion grooves 3422 extending radially outward from the intermediate diversion holes 3421 on the side of the carrier 32 facing the membrane cloth 31. By setting a plurality of small intermediate diversion holes 3421, compared with setting a large-sized diversion hole, support can be provided when the liquid storage bag 343 is under pressure. On the one hand, these intermediate diversion holes 3421 allow the liquid to flow to the middle of the membrane cloth 31, and on the other hand, the liquid is diverted radially outward, so that the membrane cloth 31 can be wetted faster and more fully.

[0049] In this embodiment, a push rod 216 is further provided in the middle of the base 21, corresponding to the liquid outlet module 34. The push rod 216 may be, but is not limited to, a lead screw structure and is electrically connected to the sub-controller 214 via a cable within the base 21. A hook 3411 is provided on the outer wall of the accommodating cavity 341, and a notch 217 is provided in the middle of the base 21. The carrier 32 is mounted on the base 21 via the hook 3411 and the notch 217. In other embodiments, the connection may also be magnetic. After the membrane cloth assembly 3 and the import assembly 2 are installed, the sensing part 33 enters the sensing range of the identification module 215. The identification module 215 can sense the sensing part 33 and identify the type of the membrane cloth assembly 3. When the type of the membrane cloth assembly 3 is compatible with the import assembly 2, the sub-controller 214 first controls the movement of the push rod 216. The push rod 216 pushes the puncturing body 344 for a preset time, so that the liquid storage bag 343 is punctured, and the liquid inside flows to the membrane cloth 31 until the membrane cloth 31 is completely wetted, and then controls the driving module 213 to turn on to enable each working head 22 to start working.

[0050] In this way, in this embodiment, a sub-controller 214 is set in the base 21 of the import component 2. The sub-controller 214 can control the operation of the driving module 213, identify the sensing component 33 through the identification module 215, and drive the push rod 216 to move, that is, the sub-controller 214 can increase the function of the import component 2 and improve its intelligence. Moreover, the sub-controller 214 communicates with the main controller 14 in the handle 1. Compared with the main controller 14 directly controlling the driving module 213, the push rod 216 and identifying the sensing component 33, the number of connectors in the first electrical connection component 212 and the second electrical connection component 13 can be reduced. Moreover, when the import component 2 needs to upgrade its function, for example, a pressure sensor can be added to the bottom of the spring 231 described below. When the pressure sensor detects that the working head 22 is pressurized to the set value, it controls the working head to be powered on. In this case of function upgrade, there is no need to change the plug-in structure of the base 21 and the handle 1.

[0051] like Figure 8 、 10As shown in FIG. 11 , in this embodiment, a plurality of mounting seats 218 are formed on the seat body 21 corresponding to the plurality of working heads 22 , and a mounting cavity 219 is formed in each mounting seat 218 . Each working head 22 is mounted in the mounting cavity 219 one by one with the aid of a flexible component 23 . The flexible assembly 23 includes a spring element 231, a first tapered sleeve 232, and a second tapered sleeve 233. The spring element 231 is positioned between the working head 22 and the bottom surface of the mounting cavity 219 to provide a flexible force. One end of the first tapered sleeve 232 is sealed and fixed to the inner bottom surface of the mounting cavity 219. The other end of the first tapered sleeve 232 is tilted upward and inward to form a first inclined section 2321. One end of the second tapered sleeve 233 is sealed and fixed to the working head 22. The other end of the second tapered sleeve 233 is tilted downward and outward to form a second inclined section 2331. The second inclined section 2331 is located inside the first inclined section 2321 and is blocked by the first inclined section 2321. After installation, the second inclined section 2331 cannot be dislodged upward. Furthermore, a rubber sleeve 234 is wrapped around the outer periphery of the first and second tapered sleeves 232 and 233 to prevent dust or liquid from entering through the gap between the first and second inclined sections 2321 and 2331.

[0052] Furthermore, the spring piece 231 includes a first contact section 2311, which extends outward in four directions to form four bent sections 2312, one end of each bent section 2312 is connected to the first contact section 2311, and the other end of each bent section 2312 is respectively connected to a second contact section 2313; the first contact section 2311 is used to contact and press the inner bottom surface of the mounting cavity 219, and the second contact section 2313 is used to be fixedly connected to the bottom surface of the working head 22; the bottom of the first contact section 2311 is also provided with a square protrusion 23111, and the inner bottom surface of the mounting cavity 219 is correspondingly provided with a square protrusion shaped groove 2191, the square protrusion 23111 is embedded in the square groove 2191 for positioning to prevent rotational dislocation; a sleeve hole 23112 is also provided on the first contact section 2311, and the sleeve hole 23112 is used to fix the sleeve 235, and one end of the sleeve 235 is connected to the working head 22 through a wire 2351. A part of the length of the wire 2351 needs to be reserved to facilitate the flexible movement of the working head 22. The other end of the sleeve 235 is electrically connected to the second terminal 2192 on the bottom surface of the installation cavity 219 through the first terminal 2352, and the second terminal 2192 is connected to the drive module 213 through the cable in the seat body 21.

[0053] The second terminal 2192 is preferably a resilient contact, pre-connected to the driver module 213 via a cable within the base 21. When installing the working head 22, the second conical sleeve 233 is first inserted through the bottom of the first conical sleeve 232 and secured to the working head 22, optionally using, but not limited to, screws. The second contact segment 2313 of the spring clip 231 is then secured to the working head 22. The sleeve 235 is then snapped into the first contact segment 2311 of the spring clip 231, and finally, the rubber sleeve 234 is installed. This integrated structure is then placed into the corresponding mounting cavity 219. The square protrusion 23111 snaps into the square groove 2191 to achieve positioning. Fasteners are then inserted through the outer bottom surface of the mounting base 218 to secure the first conical sleeve 232. This allows the spring clip 231 to provide a flexible force when the working head 22 is under pressure, allowing for flexible movement.
