Description

Technical Field

[0001] This utility model relates to the field of beauty device technology, specifically a dual-impedance detection pulse electrode head. Background Technology

[0002] With rising living standards and increased awareness of beauty, the demand for skincare has grown significantly. Especially in urban environments, air pollution, stress, and irregular lifestyles exacerbate skin problems, prompting people to seek more effective skincare solutions. Electrode needle microcurrent infusion technology stimulates collagen and elastin regeneration through microcurrents, reducing fine lines and delaying aging. Compared to traditional topical skincare products, this electro-permeable technology significantly improves ingredient absorption, resulting in more noticeable and lasting effects. With the development of non-invasive cosmetic technologies, electrode needles combine the advantages of electroporation and mesotherapy, offering more precise, safe, and convenient operation. They can intelligently adjust energy intensity according to skin type, becoming a new trend in the field of technological skincare.

[0003] However, when using existing pulse electrode heads, the electrode heads usually only consider acupuncture-related issues, resulting in poor connectivity and compatibility with related equipment. Furthermore, during physiotherapy, the associated equipment maintains continuous high-frequency operation for extended periods without adjustment mechanisms, leading to short equipment lifespan, high damage rate, and low practical value. Summary of the Invention

[0004] The purpose of this invention is to provide a dual-phase impedance detection pulse electrode head to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-phase impedance detection pulse electrode head, comprising an electrode shell and a model identification sticker, characterized in that: a model identification sticker is adhered to the right side of the electrode shell, a negative pressure adsorption component is fixedly connected to the left side of the electrode shell, and an impedance detection component is inserted into the interior of the electrode shell.

[0006] Preferably, the electrode housing includes a housing body, a locking through hole, a vent, a needle application plane, a fixing insertion hole, and a negative pressure groove. The locking through hole is provided on the side wall of the housing body. The vent is fixedly connected to the lower side wall of the housing body. The needle application plane is fixedly connected to the lower inner surface of the housing body.

[0007] Preferably, the negative pressure adsorption assembly includes a negative pressure tube, a filter front chamber, a filter rear chamber, an O-ring, and filter cotton. The left side of the electrode housing is connected to one end of the negative pressure tube via a vent, and the other end of the negative pressure tube is connected to the filter front chamber. The filter rear chamber is welded to the top of the filter front chamber, and an O-ring is fitted at the top interface of the filter rear chamber. Filter cotton is fitted inside the filter rear chamber.

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

[0009] Preferably, the impedance detection component includes an electrode plate bracket, a locking socket, a snap fastener, a push pin connecting post, an electrode needle plate, a snap fastener frame, a positioning post, a PCB-in assembly, a pin, and an impedance electrode rod. The electrode plate bracket is slidably connected to the inside of the electrode housing via a limiting rib. The locking socket is fixedly connected to one end face of the electrode plate bracket. Snap fasteners are fixedly connected to both sides of the lower end of the electrode plate bracket. The push pin connecting post is fixedly connected to the upper end face of the electrode plate bracket. The electrode needle plate is snapped into the electrode plate by the snap fastener. The push pin connecting post at the upper end of the electrode plate bracket passes through the center of the snap fastener frame and forms a slidable connection with the snap fastener frame. The PCB-in assembly is inserted into the upper end face of the snap fastener frame via a positioning post. The PCB-in assembly is threadedly connected to the housing body via a screw passing through the snap fastener frame.

[0010] Preferably, the PCB-in assembly is electrically connected to the electrode needle plate, the electrode needle plate is fixedly connected to the electrode needles and arranged in an array, and the electrode needles are made of L-grade medical stainless steel with gold plating.

The impedance electrode rod is electrically connected to the PCB-in assembly.

[0013] Preferably, two impedance electrode rods are arranged diagonally, and the bottom end of the impedance electrode rod is flush with the needle application plane inside the bottom end of the electrode shell.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes impedance electrode rods to detect whether the skin is in contact with the acupuncture surface inside the electrode housing. When both impedance electrode rods are in contact with the skin, the PCB-in assembly forms a pathway, triggering a negative pressure pump. This creates negative pressure on the electrode housing, adsorbing the skin into a flat surface before electric acupuncture. The PCB-in assembly and impedance electrode rods are connected to a circuit control board, allowing the device to identify its working and non-working states. This enables the device to perform a detection function and allows for intermittent adjustment of the device's state, preventing continuous high-frequency operation after startup and reducing the device's damage rate. Furthermore, the diagonal arrangement of the two impedance electrode rods ensures that the skin is fully attached to the acupuncture surface to form a pathway, preventing accidental activation and increasing the safety and accuracy of the electrode head.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 The present invention provides an embodiment of a dual impedance detection pulse electrode head, comprising an electrode shell 1 and a model identification sticker 2. The model identification sticker 2 is adhered to the right side of the electrode shell 1, and a negative pressure adsorption component 3 is fixedly connected to the left side of the electrode shell 1. An impedance detection component 4 is inserted into the inside of the electrode shell 1.

[0027] Specifically, the electrode housing 1 includes a housing body 101, a locking through hole 102, a vent 103, a needle application plane 104, a fixing insertion hole 105, and a negative pressure groove 106. The locking through hole 102 is opened on the side wall of the housing body 101. The vent 103 is fixedly connected to the lower side wall of the housing body 101. The needle application plane 104 is fixedly connected to the lower inner surface of the housing body 101. Four fixing insertion holes 105 are opened at the four corners of the center of the needle application plane 104. The negative pressure groove 106 is provided on the outer layer of the needle application plane 104 and communicates with the vent 103.

[0028] Specifically, the negative pressure adsorption assembly 3 includes a negative pressure pipe 301, a filter front chamber 302, a filter rear chamber 303, an O-ring seal 304, and filter cotton 305. The left side of the electrode housing 1 is connected to one end of the negative pressure pipe 301 via a vent 103. The other end of the negative pressure pipe 301 is connected to the filter front chamber 302. The filter rear chamber 303 is welded to the top of the filter front chamber 302. An O-ring seal 304 is fitted at the top interface of the filter rear chamber 303. Filter cotton 305 is fitted inside the filter rear chamber 303. An external negative pressure pump is connected to the top interface of the filter rear chamber 303, thus connecting the negative pressure pump to the negative pressure groove 106 provided inside the electrode housing 1. When the negative pressure pump starts working… This design allows air inside the negative pressure groove 106 to be drawn out, creating a pressure difference. When the lower end of the electrode head is placed close to the skin surface, the skin is attracted to one end of the electrode shell 1 due to the pressure difference. Since the needle application plane 104 protrudes from the negative pressure groove 106, when the skin is attracted to the electrode shell 1 due to the pressure difference, the skin will first contact the needle application plane 104. This design allows the target needle application area to form a standard plane and be fixed in a uniform position, avoiding needle slippage caused by skin displacement during the needle application process. It also ensures that the skin is uniform on a plane, allowing for precise control of the needle application depth. This reduces the stinging sensation caused by inconsistent needle application depth and greatly improves patient comfort.

[0029] Specifically, the negative pressure tube 301 is made of silicone, the filter cotton 305 is made of medical-grade polyester foam, and the O-ring 304 is made of fluororubber. The O-ring 304 can enhance the sealing and stability of the connection between the negative pressure adsorption component 3 and the negative pressure machine.

[0030] Specifically, the impedance detection component 4 includes an electrode plate bracket 401, a locking socket 402, a buckle 403, a push pin connecting post 404, an electrode pin plate 405, a buckle bracket 406, a positioning post 407, a PCB-in component 408, a pin 409, and an impedance electrode rod 410. The electrode plate bracket 401 is slidably connected to the inside of the electrode housing 1 via a limiting plate. The locking socket 402 is fixedly connected to one end face of the electrode plate bracket 401. Buckles 403 are fixedly connected to both sides of the lower end of the electrode plate bracket 401. The push pin connecting post 404 is fixedly connected to the upper end face of the electrode plate bracket 401. The electrode pin plate 405 is engaged with the electrode pin plate 405 via the buckles 403. The push pin connecting post 404 is fixedly connected to the upper end face of the electrode plate bracket 401. The needle connecting post 404 passes through the center of the buckle frame 406 and forms a sliding connection with the buckle frame 406. The upper end face of the buckle frame 406 is inserted into the PCB-in component 408 through the positioning post 407. The PCB-in component 408 is threadedly connected to the outer shell body 101 through the buckle frame 406 by a screw. It is rotated and connected to the hand tool through the push needle connecting post 404. At the same time, the circuit connection control contact point of the hand tool is in contact with the PCB-in component 408. When the hand tool is opened, it drives the needle application plane 104 fixedly snapped inside the electrode plate bracket 401 to vibrate at the same frequency. At the same time, the hand tool generates a pulse current through the contact connection with the PCB-in component 408, which is finally applied to the electrode needle and then to the patient's skin.

[0031] Specifically, the PCB-in component 408 is electrically connected to the electrode needle plate 405, and 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.

[0032] Specifically, the pin 409 penetrates the locking through hole 102 opened on the side wall of the electrode housing 1 and is inserted into the locking hole 402. The pin 409 can fix the electrode plate bracket 401 when not in use, prevent the electrode needle plate 405 that is stuck to the electrode plate bracket 401 from moving irregularly, and limit the movement of the electrode needle plate 405, thus preventing accidental damage to the electrode needle.

[0033] Specifically, an impedance electrode rod 410 is fixedly connected to the fixing socket 105 at the bottom 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 tightly attached to the PCB-in assembly 408. The impedance electrode rod 410 is electrically connected to the PCB-in assembly 408.

[0034] Specifically, there are two impedance electrode rods 410 arranged diagonally. The bottom end of the impedance electrode rod 410 is flush with the acupuncture plane 104 inside the bottom end of the electrode housing 1. The arrangement of the two sets of impedance electrode rods 410 diagonally flush with the acupuncture plane 104 ensures that the two impedance electrode rods 410 that are fully in contact with the skin and the acupuncture plane 104 at one end of the electrode housing 1 will form a series path to trigger the working signal of the device, which plays a double protection role.

[0035] 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 assembly 408 on the snap-fit ​​bracket 406 through the positioning post 407. Next, snap and fix the electrode needle plate 405 through the two snaps 403 at the bottom of the electrode plate bracket 401. Insert the snap-fit ​​bracket 406 and the PCB-in assembly 408 through the push pin connecting post 404 at the top of the electrode plate bracket 401. Finally, after fixing the whole assembly, align and place it inside the electrode housing 1. Fix the PCB-in assembly 408 and the snap-fit ​​bracket 406 in the threaded hole inside the electrode housing 1 through the thread, keeping the electrode plate bracket 401 inside it sliding. Then, keep the top end of the impedance electrode rod 406 electrically connected to the PCB-in assembly 404, and lock the electrode plate bracket 401 through the pin 409. Step 2: When working, connect the hand tool to the push pin connecting post 404. The circuit control contact plate and PCB-in component 408 are kept electrically connected. Then, the plug 409 is pulled out, and the electrode head is placed on the skin surface. The impedance electrode rod 410 is used to detect whether the skin is in contact with the acupuncture plane 04 of the electrode shell 1. If it is in contact, the PCB-in component 408 triggers a control signal to control the negative pressure pump to draw air, so that the negative pressure tube 301 generates a negative pressure environment and applies a certain suction force to the skin acupuncture area to ensure that the electrode head is in close contact with the skin surface. After the skin is adsorbed into a plane, the electrode plate support 401 is moved back and forth a short distance by controlling the hand tool, so that the pulse needle of the electrode needle plate 405 is inserted into the skin surface to perform pulse acupuncture, thereby stimulating the skin and awakening its vitality.
