[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0041] It should be noted that all the direction indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative position relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the direction indications will also change accordingly.

[0042] In addition, the descriptions involving "first", "second", etc. in the present application are only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" can be explicitly or implicitly included in the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the fact that a person skilled in the art can realize it, and when the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the protection scope required by the present application.

[0043] In the present application, unless otherwise explicitly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense, for example, "fixation" can be fixed connection, or detachable connection, or integral; can be mechanical connection, or electrical connection; can be direct connection, or indirect connection through intermediate medium; can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For a person skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0044] With reference to Figures 1 to 13 The present application provides a skin beautifying and introducing instrument 100 kit, which comprises a skin beautifying and introducing instrument 100 and a charging base 200 for charging the skin beautifying and introducing instrument 100, the skin beautifying and introducing instrument 100 comprises a main body 10 and an introducing head 30 mounted on the main body 10, an inner side of the introducing head 30 is provided with a circuit board 33, and an outer side is provided with a contact part 31 in contact with a human body, the contact part 31 is provided with a first contact pole piece 311 and a second contact pole piece 312 arranged at intervals; the circuit board 33 is provided with an output electronic element, the output electronic element outputs current to the first contact pole piece 311 and the second contact pole piece 312 under the current driving of a power supply 11, so as to form a skin beautifying area between the first contact pole piece 311 and the second contact pole piece 312;

[0045] The main body 10 is internally provided with a power supply 11 to be electrically connected with the circuit board 33; the output electronic element is an output circuit arranged on the circuit board 33, and the main body 10 can output different types of currents to the first contact pole piece 311 and the second contact pole piece 312 of the lead-in head 30 through the output circuit. For example, the RF radio frequency module inside the main body 10 outputs RF radio frequency waves to the first contact pole piece 311 and the second contact pole piece 312 through the output circuit. The RF radio frequency waves directly penetrate the skin, and when the RF radio frequency waves pass through the impedance formed by the skin, the RF radio frequency waves can also make the cell molecules produce strong resonance rotation (in the order of millions per second) to generate heat energy, so as to achieve the purpose of heating the collagen tissue and heating the fat cells, so that the temperature of the bottom layer of the skin instantaneously increases. The stimulation of the dermis layer can produce immediate collagen tightening and stimulate collagen regeneration. For another example, the first contact electrode and the second contact electrode are outputted with micro-current through the output circuit, so that the skin cells are in the electric field, the cell membrane becomes very permeable, and the cosmetic molecules are reduced in size through electrolysis, penetrate into the stratum corneum, and then the high-molecular nutritional substances are directly introduced into the cell interior through the electric pulse, so as to realize the nourishing effect of ordinary skin care for tens of times.

[0046] Further, the circuit board 33 is further provided with a charging electronic element, the charging electronic element forms a charging circuit, and the output circuit and the charging circuit can be switched through the arrangement of the switching electronic element. When the switching electronic element is triggered, the electrical loop between the output circuit and the first contact pole piece 311 and the second contact pole piece 312 is disconnected, and the electrical loop between the charging circuit and the first contact pole piece 311 and the second contact pole piece 312 is connected, so that the first contact pole piece 311 and the second contact pole piece 312 form the contact electrodes for charging of the power supply 11.

[0047] Specifically, the charging seat 200 includes a seat body and a PCB board 240. The seat body is provided with a receiving cavity 2101 for inserting the skin beautifying lead-in instrument 100. The PCB board 240 is accommodated in the seat body and is electrically connected with a charging terminal 241. The contact part 31 of the charging terminal 241 is located in the receiving cavity 2101 and is used for charging the skin beautifying lead-in instrument 100. The charging seat 200 is further provided with a trigger piece 250. When the skin beautifying lead-in instrument 100 is inserted into the receiving cavity 2101, the charging electrodes of the skin beautifying lead-in instrument 100, i.e., the first contact pole piece 311 and the second contact pole piece 312, are in abutting connection with the charging terminal 241 and are electrically connected. The trigger piece 250 is used for triggering the internal charging circuit of the skin beautifying lead-in instrument 100. That is, the trigger piece 250 triggers the switching electronic element, so that the internal charging circuit of the skin beautifying lead-in instrument 100 establishes an electrical loop with the charging terminal 241. The charging seat 200 charges the battery 243 inside the skin beautifying lead-in instrument 100 through the charging terminal 241 and the charging circuit.

[0048] The skin beautifying and introducing instrument 100 of the present application, by adding charging electronic elements and switching electronic elements to the circuit board 33 of the introducing head 30, when the skin beautifying and introducing instrument is used, the power supply 11 outputs current to the first contact pole 311 and the second contact pole 312 through the output electronic elements, to realize the RF frequency physiotherapy or ion introduction function. When charging is needed, the switching electronic elements are used to disconnect the electrical circuit between the output electronic elements and the first contact pole 311 and the second contact pole 312, and make the electrical circuit between the charging electronic elements and the first contact pole 311 and the second contact pole 312 conductive, so that the first contact pole 311 and the second contact pole 312 become the contact electrodes of the power supply 11, without the need to additionally set a charging plug interface or a charging electrode at the tail of the main body 10, saving space, making the battery 243 space larger, increasing the endurance, and reducing the risk of water and dust entering. At the same time, by setting the trigger 250 in the charging base 200, when the skin beautifying and introducing instrument 100 is inserted into the accommodating cavity 2101 of the charging base 200, the trigger 250 triggers the switching electronic elements to activate the charging circuit, preventing the trigger 250 from being set on the main body 10 of the skin beautifying and introducing instrument 100, and the user forgetting to trigger, resulting in a safety hazard of the charging base 200 continuously outputting current to the first contact pole 311 and the second contact pole 312 in the state of the charging circuit not being activated. At the same time, it can also prevent the user from charging with other unknown charging bases 200, resulting in a safety hazard due to the mismatch of the charging voltage.

[0049] In addition, by using the charging base 200, after the skin beautifying and introducing instrument 100 is used, the introducing head 30 is inserted into the charging base 200, the skin beautifying and introducing instrument 100 is stored, and at the same time, the skin beautifying and introducing instrument 100 can be charged, and the introducing head 30 is stored in the accommodating cavity 2101 and is not easy to contact with the external dust, reducing the attachment of bacteria and dust.

[0050] Specifically, the trigger 250 in the charging base 200 is a magnet, and the switching electronic element is a magnetic Hall switch. When the magnetic Hall switch is static, the electrical loop between the output electronic element and the first and second contact pieces 311 and 312 is conducted. When the magnetic Hall switch is triggered, the electrical loop between the output electronic element and the first and second contact pieces 311 and 312 is disconnected, and the electrical loop between the charging electronic element and the first and second contact pieces 311 and 312 is conducted. Through the magnetic Hall switch, the charging circuit is automatically switched under the external magnetic environment without manual operation by the user. That is, when the user inserts the introduction head 30 of the skin introduction instrument 100 into the charging base 200, the magnet provided in the charging base 200 triggers the magnetic Hall switch, so that the output circuit is switched to the charging circuit. Further, the first and second contact pieces 311 and 312 form two charging electrodes of the skin introduction instrument 100 and establish an electrical loop with the charging terminal 241 of the charging base 200. Thus, the user operation is facilitated, and the phenomenon of failure to charge due to forgetting to switch is avoided.

[0051] It can be understood that in actual application, the method of using a magnetic Hall switch and a magnet is not limited to the above-mentioned embodiment. For example, in other embodiments of the present application, a control button can be provided on the main body 10 of the skin introduction instrument 100 to switch the circuit, or a trigger pressing area can be provided on the introduction head 30, and a trigger protrusion can be provided on the bottom wall of the accommodating cavity 2101. The trigger pressing area is used to open and close the charging circuit. When the trigger pressing area is static, the charging circuit is disconnected. When the skin introduction instrument 100 is inserted into the accommodating cavity 2101, the trigger protrusion presses the trigger pressing area, thereby triggering the charging circuit to be in electrical connection with the battery 243 in the main body 10 of the skin introduction instrument 100. This method also belongs to the protection scope of the present application, and thus will not be described in detail here.

[0052] Specifically, the magnetic Hall switch includes a normally closed reed tube and a normally open reed tube. The normally closed reed tube is arranged between the electrical loop of the output electronic element and the first and second contact pieces 311 and 312. The normally open reed tube is arranged between the electrical loop of the charging electronic element and the first and second contact pieces 311 and 312. When the normally closed reed tube is close to an external magnet, the contact points of the spring in the normally closed reed tube are separated under the magnetic action, so that the electrical loop between the output circuit formed by the output electronic element and the first and second contact pieces 311 and 312 is disconnected. The contact points of the spring in the normally open reed tube are contacted under the magnetic action, so that the electrical loop between the charging circuit formed by the charging electronic element and the first and second contact pieces 311 and 312 is conducted, thereby realizing the switching of the circuit.

[0053] Specifically, the seat body comprises a first shell 210 and a second shell 220, the first shell 210 is sleeved outside the second shell 220, and is provided with the accommodating cavity 2101, the second shell 220 is internally provided with a cavity, and the second shell 220 is provided with a mounting groove 2201 on the surface facing the accommodating cavity 2101 of the first shell 210, the PCB 240 is mounted in the cavity, and one end of the charging terminal 241 is located in the accommodating cavity 2101 after penetrating through the second shell 220 and the first shell 210, the magnet is mounted in the mounting groove 2201, and the magnet is covered when the first shell 210 is mounted on the second shell 220, and the magnet is limited in the mounting groove 2201. The product is more beautiful, and the magnet is covered to prevent direct exposure in the accommodating cavity 2101, thereby preventing rust caused by external moisture.

[0054] It can be understood that the magnet is not limited to being mounted on the second shell 220, for example, a blind groove corresponding to the inner side of the accommodating cavity 2101 of the first shell 210 can also be provided for mounting the magnet, which also belongs to the protection scope of the present application. In order to facilitate the user to press and mount the magnet, it is preferred that the second shell 220 is provided with the mounting groove 2201 for mounting the magnet.

[0055] Specifically, one of the first contact pole piece 311 and the second contact pole piece 312 is annular, and the axis of the annular is coincident with the axis of the lead-in head 30, and the other is located in the ring and at least partially located at the axis. In the technical solution, the annular includes but is not limited to a circular ring, an elliptical ring, a square ring, a triangular ring, etc., which are not limited here. In order to enable the lead-in head 30 to rotate at various angles to achieve contact with the charging terminal 241 and establish an electrically conductive connection, the first contact pole piece 311 is provided in a circular ring shape, and the axis of the lead-in head 30 coincides with the center of the circular ring, that is, the center of the circular ring coincides with the center formed by the outer periphery of the lead-in head 30. The second contact pole piece 312 is a solid plate, which is in contact with the human skin. Of course, it can also be annular, which is not limited here, and all belong to the protection scope of the present application, and the second contact pole piece 312 is only partially located in the center of the lead-in head 30, so as to ensure that the lead-in head 30 can establish stable electrical connection when rotating at various angles.

[0056] Further, the charging terminal 241 is two charging contact spring needles 2411, the two charging contact spring needles 2411 of the charging seat 200 are arranged at intervals, and one of them is located in the middle to abut against the contact pole piece in the middle to establish electrical connection, and the other is located at a position corresponding to the ring surface of the annular contact pole piece to establish electrical connection with the annular contact pole piece. So that the lead-in head 30 can establish stable electrical connection with the charging contact spring needle 2411 in the charging seat 200 at different angles.

[0057] It can be understood that, in actual use, the two charging contact springs 2411 provided in the charging base 200 are not limited to being arranged in the middle, for example, in another embodiment of the present application, the two charging contact springs 2411 can be arranged eccentrically. Therefore, the first contact piece 311 and the second contact piece 312 are annular, and the first contact piece 311, the second contact piece 312 and the lead-in head 30 are coaxially arranged to achieve a mode in which the lead-in head 30 can be stably and electrically connected to the charging contact springs 2411 in the charging base 200 at different angles, which also belongs to the protection scope of the present application.

[0058] At the same time, the number of the charging contact springs 2411 is not limited to two, for example, in other embodiments of the present application, in order to prevent the phenomenon that the lead-in head 30 is tilted due to uneven force caused by one charging contact spring 2411 arranged in the middle and the other charging contact spring 2411 arranged eccentrically, the number of the charging contact springs 2411 is three, one of which is arranged in the middle, and the other two are symmetrically and spaced apart with respect to the charging contact spring 2411 arranged in the middle, so as to provide uniform support force for the lead-in head 30.

[0059] Specifically, the first contact piece 311 and the second contact piece 312 protrude from the surface of the contact portion 31. The first contact piece 311 and the second contact piece 312 are prevented from being in poor contact with the charging contact terminals of the external charging base 200 due to unevenness of the contact portion 31 caused by production and processing errors of parts. At the same time, the first contact piece 311 and the second contact piece 312 protrude from the surface of the contact portion 31, so that a liquid accumulation gap is formed between the first contact piece 311 and the second contact piece 312. When the lead-in head 30 is moved on the human skin, excessive skin care essence can be accumulated in the liquid accumulation gap and uniformly coated on the surface of the human skin along with the movement of the lead-in head 30, which is convenient for user operation.

[0060] Specifically, the first contact pole 311 is made of conductive material or is sprayed with a conductive coating made of plastic material; and the side of the first contact pole 311 facing the outside is constructed into a shell of the lead-in head 30, the middle part is hollowed out, the inner side of the first contact pole 311 is provided with a recessed cavity 3114, the opening of the recessed cavity 3114 is larger than the size of the circuit board 33, and the inner wall of the recessed cavity 3114 is provided with a support bone 3115, which abuts against the support bone 3115 when the circuit board 33 is installed in the recessed cavity 3114, so that there is a space for arranging electronic elements between the circuit board 33 and the bottom cavity wall of the recessed cavity 3114, and the outer periphery of the circuit board 33 is spaced apart from the recessed cavity 3114 to prevent the outer periphery of the circuit board 33 from contacting the first contact pole 311 to cause short circuit. The hollow area 3112 is provided with an insulating bracket 313, and the middle part of the insulating bracket 313 is provided with a mounting space 3131 for mounting the second contact pole 312, thereby preventing the first contact pole 311 and the second contact pole 312 from contacting and causing short circuit, and the circuit board 33 is provided with a conductive spring, a charging contact spring needle 2411, a conductive column and the like at a position opposite to the second contact pole 312, so that the circuit board 33 and the second contact pole 312 are electrically connected without welding wire, which is effective and convenient for processing and production. The switching electronic element is arranged on the side of the circuit board 33 facing the hollow area 3112, so it is located close to the outside, and is easily triggered by a magnet or other magnetic element, thereby improving the triggering accuracy.

[0061] Specifically, the end of the edge of the lead-in head 30 is tapered, thereby forming a wedge-shaped or arc-shaped guide part 3111, which is convenient for insertion into the charging base 200.

[0062] At the same time, when the charging base 200 is designed, the height of the side wall surrounding the accommodating cavity 2101 gradually increases from one side to the other side, so that when the lead-in head 30 is inserted, it supports the main body 10 of the skin beautifying lead-in instrument 100, preventing the skin beautifying lead-in instrument 100 from easily separating from the charging base 200 when only the lead-in head 30 is inserted.

[0063] Specifically, the insulating bracket 313 is a light-transmitting piece, the circuit board 33 is provided with a light source 334, and the light emitted by the light source 334 can be transmitted through the light-transmitting piece to the outside. The light source 334 can be a multi-color LED lamp bead, which emits light of different colors, frequencies and intensities under the control of a current and PWM module circuit to achieve the skin therapy effect. At the same time, it can also be used as an indicator light when the switching electronic element is triggered, which is convenient for indicating the charging state and reminding the user whether the charging is normal.

[0064] Specifically, the lead-in head 30 is further provided with a connecting bracket 34 and a locking screw 35. The connecting bracket 34 is installed on the side of the circuit board 33 away from the contact part 31 and is provided with a first connecting column 341 and a second connecting column 342. The first connecting column 341 is provided with a threaded connection hole toward the end face of the circuit board 33. The locking screw 35 passes through the circuit board 33 and is connected with the threaded connection hole of the first connecting column 341 to fix the circuit board 33 to the connecting bracket 34 to form an assembly. At the same time, the second contact pole piece 312 is clamped in the insulating bracket 313 and then integrally installed in the hollow area 3112 of the first contact pole piece 311. Then, the assembly of the circuit board 33 and the connecting bracket 34 is installed in the recess 3114 to press the second contact pole piece 312 and the insulating bracket 313 against the first contact pole piece 311. At the same time, the first contact pole piece 311 is provided with a third connecting column 3113.
