[0001] The present invention relates to the technical field of beauty instruments, and specifically to a dual - impedance detection pulsed electrode head. Background Art

[0002] With the improvement of living standards and the enhancement of beauty awareness, the demand for skin care has increased significantly. Especially in the urban environment, air pollution, stress, and irregular lifestyles have exacerbated skin problems, prompting people to seek more efficient skin care solutions. The micro - current introduction technology of electrode needles stimulates the regeneration of collagen and elastic fibers through micro - current, fades fine lines, and delays aging. Compared with traditional topical skin care products, this electro - conductance penetration technology greatly improves the absorption rate of ingredients and has more significant and lasting effects. With the development of non - invasive beauty technologies, electrode needles integrate the advantages of electroporation introduction and mesotherapy, with more precise, safe, and convenient operation, and can intelligently adjust the energy intensity according to skin types, becoming a new trend in the field of scientific skin care.

[0006] Preferably, the electrode housing includes a housing body, a locking through - hole, an air vent, a needle - applying plane, a fixed jack, and a negative - pressure groove.

[0008] Preferably, the negative pressure tube is made of silicone, the filter cotton is medical-grade polyester foam, and the O-ring is made of fluororubber.

[0009] Preferably, the impedance detection assembly includes an electrode plate bracket, a locking jack, a buckle, a push pin connecting column, an electrode needle plate, a buckle bracket, a positioning column, a PCB-in assembly, a plug, and impedance electrode rods. The electrode plate bracket is slidably connected to the inside of the electrode housing through a limiting rib. A locking jack is fixedly connected to one side end face of the electrode plate bracket. Buckles are fixedly connected to both sides of the lower end of the electrode plate bracket. A push pin connecting column is fixedly connected to the upper end face of the electrode plate bracket. The electrode plate bracket is snap-connected to the electrode needle plate through the buckle.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The present invention is provided with impedance electrode rods for detecting whether the skin touches the needle application plane inside the bottom of the electrode housing.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0019] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0021] Please refer to Figures 1-5 , an embodiment provided by the present invention: a dual - impedance - detection pulse electrode head, which includes an electrode housing 1 and a model - identification sticker 2. The model - identification sticker 2 is adhered to the right side of the electrode housing 1, and a negative - pressure adsorption component 3 is fixedly connected to the left side of the electrode housing 1. An impedance - detection component 4 is inserted into the electrode housing 1.

[0022] Specifically, the electrode housing 1 includes a housing body 101, a locking through - hole 102, an air - vent nozzle 103, a needle - applying plane 104, a fixing jack 105, and a negative - pressure groove 106. A locking through - hole 102 is opened on the side wall of the housing body 101, an air - vent nozzle 103 is fixedly connected to the lower side wall of the housing body 101, a needle - applying plane 104 is fixedly connected to the lower - end surface inside the housing body 101. Four fixing jacks 105 are opened at the four corner ends of the center of the needle - applying plane 104, and a negative - pressure groove 106 is arranged on the outer layer of the needle - applying plane 104 and is in communication with the air - vent nozzle 103.

[0023] Specifically, the negative pressure adsorption assembly 3 includes a negative pressure tube 301, a pre-filter chamber 302, a post-filter chamber 303, an O-ring 304, and a filter cotton 305. One end of the negative pressure tube 301 is inserted into the left side of the electrode housing 1 through a vent nozzle 103, and the other end of the negative pressure tube 301 is inserted into the pre-filter chamber 302. The pre-filter chamber 302 is welded to the post-filter chamber 303 at the top. An O-ring 304 is sleeved at the top interface of the post-filter chamber 303, and a filter cotton 305 is sleeved inside the post-filter chamber 303. An external negative pressure machine is connected to the top interface of the post-filter chamber 303, so that the negative pressure pump is connected to the negative pressure groove 106 provided inside the electrode housing 1. When the negative pressure machine pump starts to work, the air inside the negative pressure groove 106 can be sucked out to form a pressure difference. At this time, the lower end of the electrode head is close to the skin surface, and the skin is adsorbed at one end of the electrode housing 1 due to the action of the pressure difference. Since the needle application plane 104 protrudes from the negative pressure groove 106, when the skin is adsorbed by the electrode housing 1 due to the pressure difference, the skin will first come into contact with the needle application plane 104. Such a setting can make the target needle application area form a standard plane and be fixed at a unified position, avoiding the phenomenon of needle displacement caused by skin displacement during the needle application process, and making the skin unified in one plane, so that the needle application depth can be accurately controlled, reducing the stinging pain caused by inconsistent needle application depths, and greatly improving the comfort of the patient.

[0024] Specifically, the material of the negative pressure tube 301 is silicone, the filter cotton 305 is medical-grade polyester foam, and the material of the O-ring 304 is fluororubber. The O-ring 304 can enhance the sealing performance and stability of the connection between the negative pressure adsorption assembly 3 and the negative pressure machine.

[0025] Specifically, the impedance detection component 4 includes an electrode plate bracket 401, a locking jack 402, a buckle 403, a push pin connection column 404, an electrode needle plate 405, a buckle bracket 406, a positioning column 407, a PCB-in component 408, a plug pin 409, and an impedance electrode rod 410. The inner part of the electrode housing 1 is slidably connected to the electrode plate bracket 401 through a limiting plate. One end face of the electrode plate bracket 401 is fixedly connected to the locking jack 402. Buckles 403 are fixedly connected to both sides of the lower end of the electrode plate bracket 401. The upper end face of the electrode plate bracket 401 is fixedly connected to the push pin connection column 404. The electrode plate bracket 401 is snap-connected to the electrode needle plate 405 through the buckle 403. The push pin connection column 404 at the upper end of the electrode plate bracket 401 passes through the center of the buckle bracket 406 and forms a sliding connection with the buckle bracket 406. The upper end face of the buckle bracket 406 is plugged with the PCB-in component 408 through the positioning column 407. The PCB-in component 408 is threadedly connected to the housing body 101 through screws passing through the buckle bracket 406. It is rotationally connected to the handpiece through the push pin connection column 404. At the same time, the circuit connection control contact point of the handpiece is in contact connection with the PCB-in component 408. When the handpiece is turned on, it drives the needle application plane 104 fixedly clamped inside the electrode plate bracket 401 to vibrate at the same frequency. At the same time, the handpiece generates a pulsed current through the contact connection with the PCB-in component 408, and finally applies it to the electrode needle until it reaches the patient's skin.

[0026] Specifically, the PCB-in component 408 is electrically connected to the electrode needle plate 405. The electrode needle plate 405 is fixedly connected to the electrode needles and arranged in an array. The electrode needles are made of 316L medical-grade stainless steel with gold plating.

[0027] Specifically, the plug pin 409 passes through the locking through hole 102 opened on the side wall of the electrode housing 1 and is plugged into the locking jack 402. The plug pin 409 can fix the electrode plate bracket 401 during the non-use process, prevent the irregular movement of the electrode needle plate 405 clamped by the electrode plate bracket 401, play a role in limiting the movement of the electrode needle plate 405, and prevent accidental damage to the electrode needle.

[0028] Specifically, an impedance electrode rod 410 is fixedly connected to the fixed jack 105 at the bottom end of the electrode housing 1. The other end of the impedance electrode rod 410 passes through the electrode needle plate 405, the electrode plate bracket 401, and the buckle bracket 406 and is in close fit with the PCB-in component 408. The impedance electrode rod 410 is electrically connected to the PCB-in component 408.

[0029] Specifically, two impedance electrode rods 410 are arranged diagonally. The bottom end of the impedance electrode rod 410 is flush with the needle application plane 104 provided inside the bottom end of the electrode housing 1. The diagonal arrangement of the two groups of impedance electrode rods 410 flush with the needle application plane 104 enables the skin to fully adhere to the two impedance electrode rods 410 on the needle application plane 104 at one end of the electrode housing 1, forming a series connection path to trigger the working signal of the device, thus playing a role of double insurance.

[0030] Working principle: Step 1: Connect the negative pressure machine to the O-ring 304 to ensure the stability and sealing of the negative pressure environment. Then, align and install the PCB-in component 408 on the buckle holder 406 through the positioning posts 407. Next, connect and fix the electrode needle plate 405 through the two buckles 403 at the bottom of the electrode plate bracket 401. Insert and connect the buckle holder 406 and the PCB-in component 408 through the needle pushing connection post 404 at the top of the electrode plate bracket 401. Finally, place the whole assembly in the electrode housing 1 after fixation and alignment, and fix the PCB-in component 408 and the buckle holder 406 on the threaded holes inside the electrode housing 1 through threads, keeping the electrode plate bracket 401 inside it sliding. Then, keep one end of the top of the impedance electrode rod 406 electrically connected to the PCB-in component 404, and lock the electrode plate bracket 401 through the pin 409. Step 2: When working is required, connect the handpiece to the needle pushing connection post 404, making the circuit control contact plate in contact with the PCB-in component 408 to maintain electrical connection. Then, pull out the pin 409, place the electrode head on the skin surface, and use the impedance electrode rod 410 to detect whether the skin touches the needle application plane 04 of the electrode housing 1. If it touches, the PCB-in component 408 triggers a control signal to control the negative pressure pump to suck air, creating a negative pressure environment in the negative pressure tube 301, applying a certain suction force to the skin needle application area, ensuring the close adhesion of the electrode head to the skin surface. After sucking the skin into a flat surface, control the handpiece to make the electrode plate bracket 401 reciprocate in a short distance, so that the pulse needles of the electrode needle plate 405 are inserted into the skin surface layer for pulse needle application, achieving the effect of stimulating the skin and awakening vitality.

[0031] The above are only embodiments of the present invention, and common knowledge such as specific structures and characteristics known in the solutions is not described in detail here. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
