Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a treatment head and a treatment device. Background Technology

[0002] Currently, in the field of energy beauty or treatment devices, this type of device uses focused ultrasound energy or light energy (such as laser, intense pulsed light, etc.) to act on human tissues to achieve effects such as skin tightening, skin rejuvenation, and fat reduction.

[0003] However, existing energy-based beauty or treatment devices typically only output a single type of energy per treatment head, such as ultrasound energy or light energy. When different energy modes need to be combined for better results or to address different indications during treatment, the operator must frequently change the corresponding treatment head. This switching process not only interrupts the continuity of treatment, increases the overall operation time, and reduces treatment efficiency, but also increases operational complexity and inconvenience. Utility Model Content

[0004] The main purpose of this invention is to propose a treatment head and a treatment device that can output multiple types of energy at once while integrating EMS function without widening the treatment area, thereby reducing the operational complexity of the treatment device and facilitating its miniaturization and improved treatment efficiency.

[0005] To achieve the above objectives, the present invention provides a treatment head, the treatment head comprising:

[0006] A housing having a treatment end and an internal accommodating cavity;

[0007] An ultrasonic energy module, installed within the accommodating cavity and facing the treatment end, is used to output ultrasonic energy to the skin; and

[0016] In one embodiment, the treatment head further includes an inner shell and an acoustic membrane. The inner shell is disposed within the accommodating cavity and is used to load a medium for transmitting ultrasonic waves. The acoustic membrane is disposed on the side of the inner shell near the treatment end. The ultrasonic energy module includes a transducer, which is installed within the inner shell and is positioned opposite the acoustic membrane.

[0017] In one embodiment, the treatment head further includes a plurality of contact springs fixed to the outer wall of the inner housing, each of the contact springs being electrically connected to the main control circuit board and elastically abutting against the EMS electrode.

[0018] In one embodiment, the treatment head further includes a phototherapy module disposed on the housing and spaced apart from the ultrasonic energy module and the EMS electrode, for outputting phototherapy energy to the skin.

[0019] In one embodiment, the phototherapy module includes:

[0020] Phototherapy control panel, the phototherapy control panel being installed within the housing; and

[0021] The phototherapy lamp bead is integrated into the phototherapy control board and is electrically connected to the phototherapy control board.

[0022] In one embodiment, the treatment head further includes two phototherapy modules, which are located on both sides of the housing and arranged symmetrically.

[0023] In one embodiment, the treatment head further includes at least two sensing modules, which are disposed on both sides of the housing. Each sensing module is spaced apart from the ultrasonic energy module, the EMS electrode, and the phototherapy module, and is used to detect whether the treatment head moves and / or whether the treatment head is in contact with the skin.

[0024] In one embodiment, the sensing module is a light sensor or a linear Hall sensor.

[0040] In existing technologies, energy-based beauty devices typically employ a single-energy-output treatment head design. When switching energy modes is required during operation, the treatment process must be interrupted and the corresponding treatment head replaced. This not only prolongs the overall treatment time but also increases the complexity of device operation. Especially when multiple energy sources are needed to work synergistically, frequent treatment head changes directly impact treatment efficiency and user experience.

[0041] To address these issues, it was discovered during the research and development process that traditional treatment heads, due to structural limitations, could not simultaneously accommodate both ultrasound and electrical stimulation modules. Analysis of the spatial requirements for the two energy transmission paths revealed that planar electrode layouts would hinder the effective transmission of ultrasound. After multiple structural simulations and experimental verifications, a non-circular electrode design was ultimately adopted, ensuring sufficient contact area for electrical stimulation while avoiding any obstruction effect on ultrasound propagation.

[0042] Therefore, please refer to Figure 1 and Figure 2 This application proposes a treatment head structure including a housing 10, an ultrasonic energy module 20, and an EMS electrode 30. The housing 10 has a treatment end 10a and a receiving cavity inside the housing 10. The ultrasonic energy module 20 is installed in the receiving cavity and is positioned towards the treatment end 10a for outputting ultrasonic energy to the skin. The EMS electrode 30 is disposed on the end face of the treatment end 10a for outputting a therapeutic current to the skin. The EMS electrode 30 includes a transverse electrode portion 31 and a longitudinal electrode portion 32 connected to one end of the transverse electrode portion 31. The transverse electrode portion 31 extends along the end face of the treatment end 10a, and the longitudinal electrode portion 32 extends along the side of the housing 10.

[0043] In this embodiment, the housing 10 refers to the main structure that carries each functional module. It can be made by injection molding of engineering plastics and has a receiving cavity. One end of the housing 10 is the treatment end 10a, which is the end face from which the ultrasonic energy module 20 and EMS motor 30 output energy. The ultrasonic energy module 20 is a device that generates and transmits ultrasonic waves, forming an energy transfer interface with the skin through the treatment end 10a. The EMS electrode 30 is a conductive component that outputs electrical stimulation signals. It can be made of a silver-plated irregularly shaped metal sheet, whose special shape can adapt to different human body curves. The transverse electrode portion 31 is a flat structure extending along the end face of the housing 10. It can be formed by bending a metal sheet and is used to cover the area where the end face of the housing 10 contacts the skin. The longitudinal electrode portion 32 is a sheet-like structure extending upward from one end of the transverse electrode portion 31. It can be a bent metal sheet integrally formed with the transverse electrode portion 31, and its tilt angle matches the curvature of the side of the housing 10, used to conform to the curved surface of the side of the housing 10 that contacts the skin.

[0044] Specifically, the ultrasound energy module 20 is positioned parallel to the external skin via the treatment end 10a, ensuring that the ultrasound energy is transmitted vertically to the treatment area. The ultrasound energy module 20 and the EMS electrode 30 are arranged in a spatially staggered layout within the housing 10, ensuring that the ultrasound transmission path and the electrode conductive path do not overlap, thus avoiding energy interference.

[0045] Compared to existing technologies, traditional treatment heads only have a single energy output module, while this solution achieves the physical integration of two energy modules through structural optimization. Existing planar electrodes can obstruct the propagation path of ultrasound waves. The EMS electrode 30 of this application, while maintaining the same area of ​​the treatment end of the original treatment head, integrates EMS functionality without increasing the area of ​​the original treatment end. This is because the longitudinal electrode portion 32 of the EMS electrode 30 extends along the side of the housing 10. In other words, through the three-dimensional design of the EMS electrode 30, it is embedded in the treatment end 10a and side of the housing 10 of the treatment head. This ensures that even a small area in contact with the skin can be used for precise treatment. The transverse electrode portion 31 and the longitudinal electrode portion 32 are integrally molded, thus increasing the overall structural strength of the EMS electrode 30.

[0046] Through the above technical solution, this application solves the problem that a single treatment head cannot simultaneously output ultrasound and electrical stimulation. Treatment can be performed without interruption to change the treatment head, and the two energy modes can be applied alternately or simultaneously to the same treatment area. Since the ultrasound energy module 20 and EMS electrode 30 can output multiple energy sources at once, single treatment time is saved, significantly shortening the treatment time and simplifying the operation process, reducing the operational complexity of the treatment device, thereby improving treatment efficiency. Furthermore, the three-dimensional design of the longitudinal electrode portion 32 of the EMS electrode 30 extending along the side of the housing ensures the electrical stimulation effect while integrating EMS functionality without widening the treatment end area of ​​the original treatment head, facilitating the miniaturization of the treatment device.

[0047] Please see Figure 1 and Figure 2 This application further proposes a plurality of EMS electrodes 30 arranged at intervals around the periphery of the housing 10.

[0048] In this embodiment, "surrounding the periphery of the housing 10" refers to the distribution of multiple EMS electrodes 30 along a ring-shaped path along the outer edge of the housing 10. Specifically, they can be fixed to the end face of the treatment end 10a of the housing 10 by adhesive or snap-fit ​​methods, thereby ensuring uniform pressure distribution when the EMS electrodes 30 come into contact with the skin. "Interval arrangement" means that adjacent EMS electrodes 30 maintain a preset distance, which can be achieved by equidistant or gradient spacing. This distance is adaptively adjusted according to the size of the EMS electrodes 30 and the coverage range of the current field.

[0049] Specifically, multiple EMS electrodes 30 form a ring array along the outer edge of the housing 10, with each EMS electrode 30 independently outputting a therapeutic current. When the treatment head contacts the skin, the multiple EMS electrodes 30 form multiple current loops with the skin surface, and the electric fields generated by each loop form a superimposed region in the subcutaneous tissue. The spacing between the multiple EMS electrodes 30 is set to be larger than the effective radius of a single EMS electrode 30 to avoid excessive overlap of adjacent electric fields leading to energy concentration. Simultaneously, dynamic switching of the current path is achieved by adjusting the electrode energizing sequence.

[0050] Compared to existing technologies, traditional treatment heads typically only have a single electrode in the central area, resulting in limited current coverage and a high risk of localized burns. This approach expands the treatment area by using multiple EMS electrodes 30 arranged in a ring, while the discrete current paths formed by their spaced arrangement reduce electromagnetic interference between electrodes, enabling large-area uniform stimulation in a single treatment.

[0051] Through the above technical solution, this application achieves synchronous current output in multiple regions, covering a larger skin area without repeatedly adjusting the treatment head position, thus reducing the number of operation interruptions. The multiple EMS electrodes 30 arranged at intervals effectively disperse the current density, avoiding local tissue overheating. At the same time, the ring layout allows the EMS electrodes 30 to form a mechanical fit with the structure of the housing 10, improving the contact stability between the electrodes and the skin during treatment.

[0052] Please see Figure 1 and Figure 2 This application further proposes multiple EMS electrodes 30 positioned close to the edge of the ultrasonic energy module 20.

[0053] In this embodiment, "closely attached" means that the EMS electrode 30 maintains a minimum distance from the outer surface of the ultrasonic energy module 20. This can be achieved using conductive adhesive or a snap-fit ​​fixing structure to ensure a stable physical connection between the EMS electrode 30 and the edge of the ultrasonic energy module 20. The edge position refers to the area extending outward from the outer periphery of the ultrasonic energy module 20, specifically limited to a range extending no more than 5 millimeters outward from the outer edge of the ultrasonic energy module 20. By arranging the EMS electrode 30 in this area, effective overlap with the ultrasonic energy field of the ultrasonic energy module 20 can be achieved.

[0054] Specifically, multiple EMS electrodes 30 are closely arranged along the outer edge of the ultrasonic energy module 20, causing the release area of ​​the treatment current and the ultrasonic energy field to spatially overlap on the skin surface. Because the EMS electrodes 30 are in close contact with the edge of the ultrasonic energy module 20, the current conduction path and the direction of ultrasonic wave propagation are complementary, preventing the two energies from canceling each other out or interfering during transmission. The close contact between the EMS electrodes 30 and the edge of the ultrasonic energy module 20 also reduces energy loss in the transmission path, ensuring that the treatment current can accurately act on the target area. At the same time, this layout makes full use of the annular space at the outer edge of the ultrasonic energy module 20, avoiding an increase in the overall size of the treatment head due to a dispersed arrangement of the EMS electrodes 30.

[0055] Existing EMS electrode layouts may also create ineffective current regions due to their offset position from the edge of the energy module, reducing energy utilization. This solution directly solves the problem of fragmented energy field distribution by arranging the EMS electrodes 30 close to the edge of the ultrasonic energy module 20, enabling the two energy sources to form a superposition effect in space.

[0056] Through the above technical solution, this application achieves effective overlap between the ultrasonic energy field and the treatment current distribution area, enabling the two energy modes to produce a synergistic effect within the skin tissue. The layout of the EMS electrode 30 close to the edge of the ultrasonic energy module 20 avoids cross-interference of energy transmission paths, ensuring that the treatment current can be uniformly released along the coverage area of ​​the ultrasonic energy field. This structural design also optimizes the internal space configuration of the treatment head, achieving an integrated layout of multifunctional energy output within a limited volume.

[0057] Please see Figure 1 and Figure 2 This application further proposes that the treatment head also includes a main control circuit board 40 installed in the housing 10, and the EMS electrode 30 also includes a conductive electrode 33, which is connected to the longitudinal electrode part 32 and electrically connected to the main control circuit board 40.

[0058] In this embodiment, the main control circuit board 40 refers to the core circuit unit that integrates control signal processing and energy output. Specifically, it can be implemented using a multilayer printed circuit board and is mounted in the internal cavity of the housing 10 via a fixed bracket. It is used to centrally process the control signals of the ultrasonic energy module 20 and the EMS electrode 30. The conductive electrode 33 refers to the conductive element that connects the longitudinal electrode part 32 to the main control circuit board 40. It forms a conductive loop with the corresponding contact of the main control circuit board 40 through physical contact, and is used to establish a stable electrical signal transmission path.

[0059] Specifically, the main control circuit board 40 is fixed at a predetermined position inside the cavity of the housing 10, and its surface is provided with multiple conductive contacts. One end of the conductive electrode 33 is welded, riveted, or integrally formed with the back of the longitudinal electrode portion 32, while the other end extends into the interior of the housing 10 and makes contact with the conductive contacts of the main control circuit board 40. This layout eliminates the need for additional fasteners when installing the EMS electrode 30. By bonding and fixing it to the conductive electrode 33, the assembly process is simplified, and the poor contact problems that may occur with traditional welding or screw connections are avoided.

[0060] Compared to existing technologies, traditional treatment heads typically use wire soldering to connect the EMS electrodes to the internal circuit board. These solder joints are susceptible to breakage due to vibration or temperature changes, and require screws to fix them to the surface of the housing 10, complicating the structure. This solution replaces mechanical fastening with adhesive bonding, eliminating the assembly complexity caused by screw installation. Furthermore, it uses conductive electrodes 33 to directly contact the contacts of the main control circuit board 40, avoiding the reliability defects of the soldering process and simplifying the overall structure while ensuring electrical connection stability.

[0061] Through the above technical solution, this application solves the problem of easy loosening of the connection between the EMS electrode 30 and the main control circuit board 40. Through the synergistic effect of the design and adhesive fixation of the conductive electrode 33, the stability of the treatment current transmission path is ensured. At the same time, the assembly steps are reduced, which improves the installation efficiency of the electrode module and reduces the maintenance cost.

[0062] Please see Figure 3 and Figure 4 This application further proposes that the longitudinal cross-sectional shape of the EMS electrode 30 is L-shaped or arc-shaped.

[0063] In this embodiment, the L-shaped longitudinal cross-section means that the EMS electrode 30 presents a right-angle turn in a plane perpendicular to the end face of the housing 10. Specifically, a bending structure combining the longitudinal electrode part 32 and the transverse electrode part 31 can be formed by metal stamping process.

[0064] The longitudinal cross-sectional shape being arc-shaped refers to the EMS electrode 30 exhibiting a continuously curved geometric shape in a plane perpendicular to the end face of the housing 10. Specifically, it can be formed into an arc-shaped structure with a single radius of curvature using a molding process. This shape can match the natural curvature of the human skin surface, achieving a curved surface fit.

[0065] Specifically, when the EMS electrode 30 adopts an L-shaped cross-section, the transverse electrode portion 31 maintains parallel contact with the end face of the housing 10, and the longitudinal electrode portion 32 extends along the side of the housing 10, forming a double contact area. During the movement of the treatment head, the longitudinal electrode portion 32 guides the skin surface to slide through the tilt angle, while the transverse electrode portion 31 maintains the basic contact area.

[0066] For the EMS electrode 30 with a longitudinal cross-sectional shape of arc, its continuously curved surface forms a progressive pressure distribution upon contact with the skin, and the bending radius can be adjusted according to different treatment sites. Both cross-sectional shapes are optimized through geometric features to eliminate sharp edges at the contact interface while ensuring structural strength.

[0067] Compared to existing technologies, traditional planar electrode pads can only achieve point or line contact on a single plane, which is prone to contact interruption when the treatment head is tilted. This solution, however, increases the contact area between the EMS electrode 30 and the skin through a three-dimensional cross-section design, reducing current density and alleviating stinging sensation. The front of the transverse electrode portion 31 of the EMS electrode 30 is in direct contact with the skin. Before treatment, a gel is applied, and during the sliding treatment, the gel is pushed back and forth onto the side of the longitudinal electrode portion 32. The gel contacts the side of the longitudinal electrode portion 32 and the skin, directly conducting electricity, effectively increasing the contact area between the EMS electrode 30 and the skin.

[0068] Please see Figure 3 and Figure 4 This application further proposes that the longitudinal electrode portion 32 is inclined relative to the transverse electrode portion 31, the connection between the transverse electrode portion 31 and the end face of the housing 10 is smoothly transitioned, and the connection between the longitudinal electrode portion 32 and the side face of the housing 10 is smoothly transitioned.

[0069] In this embodiment, the smooth transition setting refers to the use of rounded or chamfered edges at the connection between the EMS electrode 30 and the housing 10. This can be achieved through mold forming or mechanical grinding to eliminate sharp edges of the electrode.

[0070] Specifically, when the transverse electrode portion 31 extends along the end face of the housing 10, its planar area in contact with the skin provides a stable current conduction path, while the upwardly inclined structure of the longitudinal electrode portion 32 adapts to the curvature of the side surface of the housing 10 in contact with the skin. The rounded corner design at the connection between the transverse electrode portion 31 and the end face of the housing 10 reduces local pressure on the skin from the electrode edge, while the rounded corner treatment at the connection between the longitudinal electrode portion 32 and the side surface of the housing 10 prevents skin irritation caused by friction during treatment. The inclined connection of the transverse electrode portion 31 and the longitudinal electrode portion 32 forms an irregular structure, ensuring that the EMS electrode 30 maintains close contact with the skin in different areas of the end face and side surface of the housing 10, thereby ensuring a uniform distribution of the treatment current on the skin surface.

[0071] Compared to existing technologies, traditional treatment heads typically employ planar electrode structures, which cannot simultaneously accommodate the varying curvatures of the end face and sides of the housing 10, resulting in insufficient contact area between the electrode and the skin or concentrated local pressure. This solution utilizes an irregularly shaped combination of the transverse electrode portion 31 and the longitudinal electrode portion 32, enabling the EMS electrode 30 to cover the contact areas of different curved surfaces of the housing 10. The tilted longitudinal electrode portion 32 further optimizes the fit between the electrode and the curved skin. Simultaneously, the tilted longitudinal electrode portion 32 increases the overall structural strength and installation space of the EMS electrode 30, allowing sufficient space to install the contact spring 70 and the conductive electrode 33, enabling external electrical energy to be transmitted to the EMS electrode 30 and ultimately applied to the human body.

[0072] In addition, existing electrode pads often have right-angled edges, which can easily cause mechanical irritation to the skin during treatment. The smooth transition structure of this solution significantly reduces the risk of skin damage by eliminating edge sharpness.

[0073] Through the above technical solution, this application can improve the stability of the EMS electrode 30 in contact with the skin, avoid the problem of uneven current distribution caused by poor contact, and reduce the mechanical stimulation of the skin by the electrode edge, thereby improving the safety and comfort of the treatment process.

[0074] Please see Figures 2 to 4 This application further proposes that the EMS electrode 30 in the treatment head also includes a mounting post 34, which is connected to the longitudinal electrode part 32; the mounting post 34 is used to snap onto the cavity wall.

[0075] In this embodiment, the mounting post 34 refers to a columnar support structure that is integrally or separately connected to the EMS electrode 30. It can be achieved through injection molding or machining, and its length and diameter can be adjusted according to the internal space of the housing 10. Physical embedding enhances the contact area between the EMS electrode 30 and the housing 10. "Snap-fitted to the inner wall of the housing 10" means that the end of the mounting post 34 is provided with a barb or protrusion structure, which can be made of elastic plastic or metal. When the mounting post 34 is inserted into the housing 10, the barb forms an interference fit with the pre-set groove on the inner wall of the housing 10, achieving self-locking fixation through the elastic deformation of the material.

[0076] Specifically, after the mounting post 34 and the EMS electrode 30 are rigidly connected by integral molding or welding, they are inserted into the internal cavity of the housing 10 through a pre-drilled hole on the side wall of the housing 10. The barb at the end of the mounting post 34 undergoes elastic deformation under pressure from the inner wall of the housing 10 during insertion. When the barb moves to the corresponding groove position, it returns to its original shape, forming a mechanical interlock. This embedded fixing method ensures that when the treatment head contacts the skin, the lateral displacement of the EMS electrode 30 is limited by the snap-fit ​​structure between the mounting post 34 and the inner wall of the housing 10, while the longitudinal displacement is constrained by the interlocking action of the barb and the groove. Simultaneously, the snap-fit ​​structure eliminates the auxiliary processes required for welding or screw fixing; during assembly, only pressing is needed to position the electrode assembly.

[0077] Compared to existing technologies, traditional electrodes are only fixed to the surface of the housing 10 by adhesive bonding. This makes them prone to displacement under high-frequency vibration of the treatment head or external pressure, resulting in poor contact between the electrode and the circuit board. This solution forms a dual fixing mechanism by engaging the mounting post 34 with the inner wall of the housing 10. This maintains the flatness of the EMS electrode 30 in contact with the skin and counteracts the influence of external forces on the electrode position through internal mechanical interlocking. It also simplifies the assembly steps of the electrode assembly.

[0078] Please see Figures 2 to 4 The present application further proposes that the treatment head also includes an inner shell 50 and an acoustic membrane 60. The inner shell 50 is disposed in the accommodating cavity and is used to load the medium for transmitting ultrasound. The acoustic membrane 60 is disposed on the side of the inner shell 50 near the treatment end 10a. The ultrasound energy module 20 includes a transducer, which is installed in the inner shell 50 and is positioned opposite the acoustic membrane 60.

[0079] In this embodiment, the inner shell 50 refers to a closed container for containing the ultrasonic transmission medium. Specifically, it can be implemented using an injection-molded plastic shell. Its inner cavity shape matches the transducer's shape. It is installed within the cavity of the shell 10 via a fixing structure to stably store the liquid or gel medium to form an ultrasonic transmission path. The ultrasonic energy module 20 includes a transducer, which is a piezoelectric element that converts electrical energy into ultrasonic waves. Specifically, it can be implemented using a spherical cap-shaped piezoelectric ceramic. Its electrode surface is connected to an external power source via wires and is installed at the bottom of the inner shell 50. It is used to generate high-frequency mechanical vibrations in water to generate ultrasonic waves. The acoustic membrane 60 is a flexible sealing layer that allows ultrasonic waves to penetrate. Specifically, it can be implemented using a silicone film. Its edges are sealed to the end face of the treatment end 10a via heat fusion. It is used to isolate the external environment while ensuring that ultrasonic energy is transmitted to the skin surface with minimal loss. Furthermore, the inner shell 50 is equipped with a pressure balancing tube to balance the pressure difference caused by thermal expansion and contraction inside the inner shell 50; at the same time, the inner shell 50 is also equipped with an NTC temperature sensor to detect the temperature inside the inner shell 50, preventing the temperature of the inner shell 50 from becoming too high due to continuous operation and causing harm to the human body.

[0080] Specifically, when the transducer is powered on, the generated ultrasonic waves are transmitted through the medium inside the inner housing 50 to the acoustic diaphragm 60, and then act on human tissue. The rigid structure of the inner housing 50 provides a stable mounting platform for the transducer, and its internal medium capacity can be set to, for example, 50 ml to ensure the continuity of the ultrasonic wave transmission path. The acoustic diaphragm 60 is aligned with the transducer, allowing the focusing area of ​​the ultrasonic beam to be precisely aimed at the treatment site. This layout allows the ultrasonic energy module 20 to form an independent functional unit inside the housing 10, with its external contour adapted to the shape of the housing 10, reserving installation space for the integration of other treatment modules.

[0081] Through the above technical solution, this application achieves spatial integration of ultrasound therapy functions and other energy therapy modules within a single treatment head. Operators can switch between different energy modes without changing the treatment head, ensuring the continuity of the treatment process and reducing operation time. The sealed fit between the inner shell 50 and the acoustic membrane 60 prevents liquid leakage and ensures efficient ultrasound transmission. The suspended installation of the transducer within the inner shell 50 effectively reduces the transmission of mechanical vibration to the shell 10 structure, lowering the equipment's operating noise.

[0082] Please see Figure 2 and Figure 3 This application further proposes that the treatment head also includes a plurality of contact springs 70 fixed to the outer wall of the inner housing 50, each contact spring 70 being electrically connected to the main control circuit board 40 and elastically abutting against the EMS electrode 30.

[0083] In this embodiment, the contact spring 70 refers to an elastic metal component with conductive properties, specifically made of phosphor bronze or beryllium copper through stamping. It generates contact pressure through elastic deformation. The design of fixing the contact spring 70 to the outer wall of the inner housing 50 allows the inner housing 50, as a carrier of functional modules, to pre-integrate the contact spring, achieving standardized docking with the main control circuit board 40. Elastic contact refers to the pressure contact formed between the contact spring 70 and the EMS electrode 30 through elastic deformation. This can be achieved using an arc-shaped or wave-shaped structure design, which compensates for assembly tolerances through the spring's own deformation, ensuring reliable contact between the EMS electrode 30 and the main control circuit board 40 at all times.

[0084] Specifically, after the contact spring 70 is fixed to the outer wall of the inner housing 50, it forms an electrical connection with the main control circuit board 40 through plug-in or soldering. When the EMS electrode 30 is installed into the housing 10, the free end of the contact spring 70 makes elastic contact with the conductive electrode 33 of the EMS electrode 30, and the deformation of the contact spring 70 is automatically adjusted according to the electrode position. This contact method eliminates the need for additional soldered wires, reducing the complexity of the circuit layout. The elastic contact between the contact spring 70 and the EMS electrode 30 can offset positional deviations during assembly, avoiding contact failure caused by vibration or thermal expansion and contraction.

[0085] In some specific embodiments, the contact spring 70 can be configured as a dual-contact structure, such as a forked design, simultaneously forming contact with two different positions of the EMS electrode 30, thereby improving conductivity reliability. The contact spring 70 can be fixed by screw fastening or snap-fit ​​embedding, for example, by providing a positioning groove on the outer wall of the inner housing 50, inserting the contact spring 70 into the positioning groove, and fixing it by heat fusion.

[0086] Existing rigid contact structures cannot compensate for component tolerances and are prone to poor contact due to vibration. This solution replaces traditional wires with the elastic contact spring 70, simplifying the circuit connection process. At the same time, the contact pressure is adaptively adjusted by the deformation of the spring, improving the stability of signal transmission.

[0087] It is worth noting that the energy connection of the EMS electrode 30 in this application is achieved by designing a flexible FPC, on which the aforementioned contact spring 70 is soldered. The contact spring 70 is connected to the EMS electrode 30 and is connected to the main control circuit board 40 through the flexible FPC.

[0088] Please see Figure 2 and Figure 3 This application further proposes that the treatment head also includes a phototherapy module, which is disposed on the housing 10 and spaced apart from the ultrasonic energy module 20 and the EMS electrode 30, for outputting phototherapy energy to the skin.

[0089] In this embodiment, the phototherapy module refers to a component capable of emitting light of a specific wavelength, which can be implemented using an LED array or a laser diode. Different wavelengths of light exert a photobiological regulatory effect on the skin. The spacing arrangement refers to the physical separation between the phototherapy module and the ultrasonic energy module 20 and EMS electrode 30. This can be achieved by setting an isolation bracket or a cavity structure inside the housing 10 to avoid mutual interference when different energy outputs occur.

[0090] Specifically, the phototherapy module is integrated into a predetermined location within the housing 10, such as at the edge of the end face of the housing 10 or circumferentially surrounding the ultrasonic energy module 20. The installation location of the phototherapy module is spatially isolated from the installation location of the ultrasonic energy module 20, ensuring that the light radiation path and the ultrasonic wave conduction area do not overlap. During treatment, the phototherapy module can independently output red, blue, or near-infrared light, working synergistically with ultrasonic energy and EMS current. For example, red light promotes collagen regeneration, ultrasonic waves heat deep tissues, and EMS current stimulates muscle contraction.

[0091] Compared to existing technologies, existing treatment heads can only achieve single energy output by replacing different modules. For example, when using ultrasound or phototherapy functions alone, the corresponding treatment head needs to be disassembled and reinstalled. This solution, through a multi-module integrated design, achieves the technical effect of simultaneously outputting phototherapy, ultrasound, and electrical stimulation energy within a single treatment head, or simultaneously outputting any two of these energies within a single treatment head. It also allows switching between outputting different types of energy, eliminating treatment interruptions caused by frequent treatment head replacements, shortening overall operation time, and reducing the complexity of equipment use. The spaced arrangement of different energy modules avoids physical interference between optical elements and the ultrasound transducer 22, ensuring the independence and stability of each energy output path.

[0092] Please see Figure 2 and Figure 3 This application further proposes a phototherapy module including a phototherapy control board installed in the housing 10 and phototherapy lamp beads integrated into the phototherapy control board.

[0093] In this embodiment, the phototherapy control board refers to the circuit board that carries the phototherapy LED beads. Specifically, it can be implemented using a flexible circuit board or a rigid printed circuit board, and the phototherapy LED beads are integrated onto the substrate using surface mount technology. This component acts as an independent control unit to regulate the output of light energy, ensuring parallel operation with the ultrasonic energy module 20.

[0094] Specifically, the phototherapy control board is fixed inside the housing 10 to form an independent installation structure. When the ultrasound energy module 20 outputs energy through the treatment end 10a, the phototherapy lamp beads synchronously emit light energy. The two energy modes are spatially separated and output in parallel to avoid mutual interference between energy fields.

[0095] Please see Figure 2 and Figure 3 Furthermore, this application proposes that the treatment head also includes two phototherapy modules, which are located on both sides of the housing 10 and arranged symmetrically.

[0096] In this embodiment, symmetrical arrangement means that the two phototherapy modules are mirror-distributed with the central axis of the housing 10 as the reference. Specifically, this can be achieved by setting the same number of mounting positions on both sides of the housing 10 and maintaining geometric symmetry, in order to balance energy distribution and expand the coverage area.

[0097] Specifically, the phototherapy control board is fixed inside the housing 10, and the two phototherapy modules are installed on the left and right sides of the housing 10 respectively. The symmetrical layout ensures that the light energy evenly covers the treatment area, avoiding local overheating or treatment blind spots caused by concentrated energy on one side.

[0098] During treatment, the two phototherapy modules can work simultaneously or alternately, switching between different energy modes without interrupting the treatment, thus maintaining treatment continuity. The symmetrical arrangement of the structural design further optimizes the center of gravity distribution of the treatment head, reducing energy output deviation caused by equipment tilting during operation.

[0099] Compared to existing technologies, where a single treatment head can only accommodate a single phototherapy module, resulting in limited energy coverage and the need for frequent head replacements, this solution utilizes two symmetrically arranged phototherapy modules on both sides. This not only expands the energy application area but also integrates multiple energy modes through a modular design, avoiding interruptions during treatment and increased operational complexity.

[0100] Please see Figure 2 and Figure 3 This application further proposes that the treatment head also includes at least two sensing modules, which are located on both sides of the housing 10. Each sensing module is spaced apart from the ultrasonic energy module 20, the EMS electrode 30 and the phototherapy module, and is used to detect whether the treatment head moves and whether the treatment head is in contact with the skin.

[0101] In this embodiment, the sensing module refers to a sensor component that can detect changes in physical position or contact status, used to detect whether the treatment head has moved and whether the treatment head is in contact with the skin.

[0102] Specifically, the left and right sensing modules need to detect skin contact simultaneously to prevent the treatment head from being pressed firmly against the skin on one side while the other side is raised or not pressed against the skin, which could cause the ultrasound energy to damage the skin.

[0103] In addition to detecting fit, the treatment head can also be detected by combining two sensing modules. When sliding close to the skin, the values ​​received by the sensing modules will fluctuate. The changes in the values ​​of the two sensing modules will not be consistent during the sliding. The state of fit and sliding of the treatment head on the skin can be determined by judging the fluctuation and consistency of the values ​​of the sensing modules.

[0104] Compared to existing technologies, traditional devices lack a real-time monitoring mechanism for the treatment head's status, requiring operators to rely on visual observation to determine the device's position, which is prone to unstable energy output due to human error. This solution, through spatial collaborative detection using dual-sensor modules, can dynamically capture the three-dimensional displacement and contact state changes of the treatment head, achieving closed-loop control of energy output.

[0105] This application further proposes that the sensing module adopts a light sensor or a linear Hall sensor.

[0106] In this embodiment, the light sensor is a device that detects the gap between objects by receiving changes in the intensity of reflected light. Specifically, it can be implemented by combining an infrared emitting tube and a photosensitive receiving tube. The degree of fit between the treatment head and the skin is determined by measuring the change in the intensity of reflected light on the skin surface.

[0107] A linear Hall sensor is a device that outputs an electrical signal by sensing a linear change in magnetic field strength. Specifically, it can be implemented using an integrated Hall effect chip. It determines whether the treatment head has moved by detecting the displacement of the magnet inside the treatment head.

[0108] Specifically, the light sensor emits light signals to the skin surface and receives reflected signals. When the treatment head is not fully in contact with the skin, the intensity of the reflected light is lower than a preset threshold, and the energy module is prohibited from starting. When the treatment head moves, causing the gap between it and the skin to increase, the intensity of the reflected light continues to fluctuate, and the output of the energy module is interrupted in real time.

[0109] Linear Hall effect sensors detect changes in the magnetic field inside the treatment head. When the treatment head moves in three-dimensional space, the change in magnetic field strength is converted into a voltage signal, triggering the energy module to stop working. Neither type of sensor requires direct contact with the skin surface, avoiding false triggering caused by sweat or oil, and is unaffected by external electromagnetic interference.

[0110] This utility model also proposes a therapeutic device, which includes a handheld component and a treatment head; the treatment head is detachably connected to the handheld component, and the specific structure of the treatment head is as described in the above embodiments. Since this therapeutic device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0111] This solution combines ultrasound, EMS electrical stimulation, and red and yellow phototherapy into a single treatment head, equipped with two photosensors. During ultrasound treatment, EMS electrical stimulation and red and blue phototherapy are simultaneously output. The ultrasound energy is focused into the subcutaneous tissue; under normal treatment energy conditions, the skin barely feels the ultrasound energy. EMS electrical stimulation acts on the skin's nerves and muscles, producing a tapping or lifting sensation, enhancing the user experience. Simultaneously, EMS electrical stimulation provides an immediate lifting effect, complementing the long-term effects of ultrasound. The phototherapy output during ultrasound treatment reduces inflammation and pain, and promotes healing. The simultaneous output of all three energy sources, or the selective output of one or two of them, significantly shortens treatment time and can be adjusted according to actual usage, thereby improving the treatment experience.

[0112] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
