[0028] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0029] like Figure 1 As shown, a fascia knife according to this application includes a plastic body 1, a first metal massage head 2, a second metal massage head 3, a transparent partition 4, a heating wire 8, a microcurrent positive electrode 6, and a microcurrent negative electrode 7. This design aims to improve the practicality and therapeutic effect of the device.

[0030] The plastic body 1 of this fascia knife serves as the main outer shell, primarily supporting other components. One side is designed with an ergonomic handle for easy gripping and operation; the other side has a pre-installed recessed space for mounting metal massage heads 2 and 3. The plastic body 1 can be injection molded, and corresponding grooves 31 and fixing slots are provided inside to ensure the metal massage heads can be securely installed.

[0031] The metal massage head 2 is a massage component made of metal. Its shape is designed according to human anatomy to fit specific parts of the body in an arc or curved form, allowing for better skin contact and massage therapy. The metal massage head 2 is located only on one side of the plastic body 1 and is embedded within it using an interference fit or other fixing structure. During manufacturing, it can be processed using a metal material with good electrical conductivity, such as aluminum alloy or copper alloy, and polished to make its surface smoother and less irritating.

[0032] The second metal massage head 3 is mirror-symmetrical in shape to the first metal massage head 2, designed to meet the need for symmetrical treatment of both sides of the limbs or muscle tissues. Like the first metal massage head 2, it is mounted on the same side of the plastic body 1, but positioned at opposite ends. Similarly, the second metal massage head 3 can be manufactured using the same technology as the first metal massage head 2.

[0033] The transparent partition 4 is designed to be inserted between the metal massage head 1 2 and the metal massage head 2 3 (see details). Figure 3 Its function is not only to physically separate the two to prevent accidental interference that may be caused by direct contact, but also to make the device more visible so as to facilitate observation of the actual working status or hygiene inspection during the cleaning process. In order to ensure stable insertion and prevent falling off, a snap-fit ​​or locking device can be added to both ends of the transparent partition 4 to lock it in the corresponding position. At the same time, this component should be made of a transparent material with good impact resistance and abrasion resistance, such as polymethyl methacrylate (PMMA) or polycarbonate (PC).

[0034] There are two sets of heating wires 8, which are respectively arranged inside the metal massage head 1 2 and the metal massage head 2 3 (see details). Figure 4 The function of the heating wire 8 is to generate appropriate heat during use to further promote blood circulation and thus enhance the fascia relaxation effect. Each set of heating wires 8 is connected to the power supply of the controller via leads, forming an independent and controllable heating circuit. Technically, resistive materials such as nickel-chromium wire can be wound to a suitable length and diameter, and then fixed to the predetermined position and encapsulated by adhesive or welding.

[0035] The microcurrent positive electrode 6 is one of the core components for achieving muscle relaxation through auxiliary electrical pulses. Each massage head has a set of microcurrent positive electrodes 6 located in the area above the corresponding metal massage head. It typically consists of conductor leads and connected contacts, and needs to be precisely inserted into pre-designed micro-mounting channels. In actual manufacturing, the tiny contact parts can be made using stainless steel needle tips, and then accurately implanted into the target area using precision assembly tools to complete the assembly.

[0036] The installation position and function of the microcurrent negative electrode 7 are similar to those of the aforementioned microcurrent positive electrode 6, only in the opposite direction, located at the other end of each group. This arrangement forms a complete closed circuit to guide a weak direct current within a set range through the surface of the skin to penetrate deeper into the tissues, providing an additional relaxing effect. The manufacturing process is roughly similar, including selecting appropriate materials to create components and fixing them in place using micro-pressing and riveting techniques.

[0037] By setting up two sets of independent, non-interfering, yet flexibly coordinated microcurrent mechanisms, the possibilities of microcurrent paths formed during the operation of the entire system are effectively increased. This diverse combination results in a wider and more uniform current coverage per unit area, enhancing its potential to provide targeted services to different muscle groups, ultimately achieving excellent effects in strengthening and assisting in muscle relaxation. Specifically, when the device is turned on, the two microcurrent sources drive current flow along different paths, which significantly widens the entire effective range, allowing users to reach an optimal state of relaxation in a short time, while avoiding discomfort that might occur due to a single current path.

[0038] like Figure 3 As shown, in one embodiment, the plastic body 1 of a fascia knife according to this application is composed of two parts, which are spliced ​​together by a mirror-symmetrical design. This design makes the entire plastic body 1 form a complete integral structure, which facilitates production and assembly while ensuring structural strength. The mating surfaces of the two symmetrical parts are precisely designed to ensure a tight and gapless fit during installation, while also facilitating the embedding of other internal components. Specifically, splicing is achieved by setting buckles, screws, or other connection methods to ensure that the assembled body has good mechanical properties and safety in use.

[0039] For example, two independent plastic parts can be produced using injection molding. For instance, two perfectly symmetrical plastic shells can be machined using a mold, and then these shells can be joined together at specific locations using slots or adhesive bonding. During assembly, metal massage head 2 and metal massage head 3 are pre-positioned on their respective sides, ensuring that the transparent partition 4 can be accurately inserted between the two metal massage heads. This joining method helps improve the assembly efficiency of the equipment and the stability of the overall structure.

[0040] like Figure 3As shown, in one embodiment, the metal massage head of a fascia knife of this application is connected to the plastic body 1 in a specific manner, forming a robust and compact whole. As an important component of the fascia knife, the position and structural arrangement of the metal massage head are crucial to the product's function. The metal massage head consists of two parts: a first metal massage head 2 and a second metal massage head 3, which are mirror-symmetrical in shape and respectively installed on both sides of the front end of the plastic body 1. This design helps improve operational flexibility and force uniformity during use. Furthermore, to further optimize component assembly, the metal massage head is designed to be embedded inside the plastic body 1, thus forming a smooth and unobtrusive overall appearance, and is separated by a transparent partition 4, ensuring the independence and stability of the structures.

[0041] The plastic body 1 consists of two components: a first plastic shell 11 and a second plastic shell 12, which are spliced ​​together. The first metal massage head 2 and the second metal massage head 3 are fixed to designated positions on the two plastic shells using snap-fit ​​or adhesive methods. This modular assembly method facilitates production and subsequent maintenance. For example, in the production process, precise positioning can be achieved by first assembling the metal massage heads with the transparent partition 4 and then sealing the entire assembly.

[0042] Specifically, a dedicated hole can be reserved on the inside of the plastic shell for the embedded assembly of the metal massage head, and the connection can be ensured by ultrasonic welding or screw fastening. At the same time, it can be ensured that the transparent partition 4 can be smoothly inserted and firmly placed between the two metal massage heads, thereby completing the assembly of the entire structure.

[0043] like Figure 3 and Figure 4 As shown, in one embodiment, the metal massage head 2 and metal massage head 3 of the fascia knife of this application are respectively disposed on the other side of the plastic body 1, and their shapes are mirror-symmetrical. To achieve the electrothermal function, both metal massage head 2 and metal massage head 3 have grooves 31 inside, and the heating wire 8 is embedded in the grooves 31, forming a tight mounting structure. This design not only ensures that the heating wire 8 is effectively fixed in the corresponding position, but also facilitates the positioning of components during processing and assembly. Furthermore, a transparent partition 4 is inserted between metal massage head 2 and metal massage head 3, further ensuring the separation and stability of the two metal massage heads.

[0044] For example, a metal massage head with a groove 31 can be prepared using a molding process. Then, the heating wire 8 is placed in the groove 31 and fixed by gluing or pressing to ensure that the heating wire 8 does not shift or loosen. Specifically, the heating wire 8 can use a resistance heating material and be connected to an external circuit module via wires to supply current for heating. Simultaneously, this assembly method can also match the respective layout requirements of the micro-current positive electrode 6 and the micro-current negative electrode 7, thereby constructing a complete functional component.

[0045] like Figure 5 As shown, in one embodiment, the fascia knife of this application further incorporates an infrared light strip 5. This light strip is disposed inside a transparent partition 4, thereby optimizing its specific location. The transparent partition 4 itself acts as a separating structure, separating the metal massage head 2 from the metal massage head 3. Its spatial arrangement allows its central area to accommodate the infrared light strip 5 without direct contact or interference with the massage heads, ensuring structural integrity and functional zoning. The infrared light strip 5 is a device with wavelength-specific radiation light sources. The transparent partition 4 allows its light to penetrate to the external space, while avoiding the potential risks associated with exposing the light source to the outside.

[0046] For example, an embedded installation method can be used. First, the infrared light strip 5 is fixed within a customized frame, and then it is fully assembled into the reserved cavity of the transparent partition 4. The transparent partition 4 is designed with a certain support structure and fixing channels to ensure the positional accuracy of the infrared light strip 5, preventing loosening or displacement, and also facilitating later maintenance or replacement of parts. Specifically, through welding, snap-fit ​​connection, or bonding processes, the transparent partition 4 is firmly assembled with the metal massage head 2 and the metal massage head 3, ultimately completing the integrated construction of the fascia knife.

[0047] like Figure 1 As shown, in one embodiment, the handle portion of the plastic body 1 of the fascia knife of this application has been improved to better fit the user's grip requirements. By adding anti-slip texture 13, the friction between the hand and the handle is increased during gripping, effectively preventing slippage due to sweating or improper force during use. The anti-slip texture 13 consists of a surface structure with a certain geometric shape or concave-convex design, and can cover the handle surface in a dot matrix, stripe, or irregular distribution. The position of the anti-slip texture 13 corresponds to the user's tiger's mouth area and fingertip area, optimizing ergonomic performance.

[0048] Specifically, a specific anti-slip texture structure can be formed directly on the surface of the handle after the plastic body 1 is produced using a molding process. Another method is post-processing, where anti-slip textures 13 are created on the smooth handle surface using equipment such as a knurling machine. Regardless of the method used, it is essential to ensure the strong connection between the anti-slip textures 13 and the plastic body 1, as well as surface consistency, to ensure that the overall aesthetics and functionality of the handle are not affected.

[0049] like Figure 1 As shown, in one embodiment, the metal massage head 2, metal massage head 3, and transparent partition 4 of the fascia knife of this application feature a unique design. The outer edges of these three components adopt a wavy structure, which not only conforms to the complex curves of the human body surface but also provides additional massage effects. Simultaneously, to reduce skin irritation during use, the surfaces of the aforementioned components are all streamlined and smooth, avoiding sharp angles or uneven areas. This structural design is suitable for areas requiring precise control of force and comfort, and ensures consistency across different usage orientations. The aforementioned wavy and streamlined design features are directly formed through mold processing, thus eliminating the need for additional post-processing steps.

[0050] Specifically, the first metal massage head 2 is located at one end of the plastic body 1 and is recessed inward; a mirror-symmetrical second metal massage head 3 is installed on the opposite side of the body; and a transparent partition 4 is inserted between the two to separate them. The transparent partition 4 is fixed with a snap-fit ​​mechanism, making overall assembly more convenient and reliable. For example, during the manufacturing stage, massage head parts with wavy edges and smooth curved surfaces can be machined using CNC machine tools, ensuring dimensional accuracy to meet assembly requirements and thus satisfying specific structural requirements in the design.

[0051] In one embodiment, one side of the plastic body 1 of the fascia knife of this application is a handle structure for easy operation, while the other side integrates related components with physiotherapy functions. Metal massage heads 1 and 2 are respectively mounted on this side of the plastic body 1, and are mirror-symmetrical to achieve multi-angle pressing effects. Two sets of heating wires 8 are embedded inside the metal massage heads 1 and 2 to provide the heat support required for heat therapy. The microcurrent positive electrode 6 and microcurrent negative electrode 7 are located at one end and the other end of the two metal massage heads respectively, forming a key part of the microcurrent output circuit.

[0052] A transparent partition 4 is inserted between the first metal massage head 2 and the second metal massage head 3, ensuring their independence while not obstructing the user's observation of the device's operation. The power supply design is crucial for the functionality of this fascia knife. By fixing the power cord to the plastic body 1 and connecting it to an external power source, a stable operating energy is provided to the heating wire 8, infrared lamp strip 5, and micro-current positive and negative electrodes, thus constructing a complete circuit architecture.

[0053] For example, detachable or embedded interfaces can be used to ensure reliable connection between the power cord and the external power source, while ensuring a reasonable and concealed wiring path. This improves the overall integration of the product's appearance while maintaining power transmission efficiency. Specifically, a circuit branching control scheme can be used to precisely deliver the required power to the locations of each functional component, achieving the goal of normal equipment operation.

[0054] like Figure 2 As shown, in one embodiment, the plastic body 1 of a fascia knife of this application is provided with a structure for connecting an external device at one end. This structure is a threaded connector 14, which is installed at the end of the plastic body 1 away from the handle and is fixedly connected to the plastic body 1. The specific design of the threaded connector 14 allows the external device to be connected to the fascia knife via a thread. Through this installation method, the fascia knife can expand its functions during use while ensuring the stability of the device connection.

[0055] The threaded connector 14 has a standard external or internal thread structure, depending on the actual requirements. For example, in one implementation, a metal insert with a threaded portion can be pre-embedded into the plastic body 1 using injection molding, followed by assembly using a mold. In another implementation, the threaded connector 14 can be designed as an integral structure that mates with the plastic body 1, with the thread shape formed through subsequent machining to ensure overall structural consistency. This achieves precise installation and secure connection of the components.

[0056] In actual operation, when using this device, the user can hold the handle to control the movement and direction of the entire fascia knife. Then, the heating wire 8, once energized, heats the metal massage head, generating an appropriate temperature that helps soothe muscles and improve blood circulation. Simultaneously, the microcurrent positive electrode 6 and microcurrent negative electrode 7 are respectively located at both ends of the metal massage head, delivering a stable, weak current stimulation to the body during use, further enhancing the massage effect. Because the transparent partition 4 is inserted between the first metal massage head 2 and the second metal massage head 3, it effectively isolates the two and prevents them from contacting each other. The operator can choose to use either the first metal massage head 2 or the second metal massage head 3 to contact the skin, achieving symmetrical pressure and physiotherapy functions during exercise or rehabilitation treatment, thus completing the entire fascia knife's working process.

[0057] The specific embodiments described above further illustrate the purpose, technical solutions, and beneficial effects of the embodiments of this disclosure. It should be understood that the above descriptions are merely specific embodiments of the embodiments of this disclosure and are not intended to limit the scope of protection of the embodiments of this disclosure.
