Description

Technical Field

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

[0002] In the cosmetic treatment industry, treatment heads, as a type of medical aesthetic device, are widely used in home settings due to their ease of operation. There are many types of treatment heads, including ultrasonic treatment heads and light therapy heads. Different types of treatment heads generate different types of energy (such as ultrasound and light waves) that act on the treatment area to achieve different therapeutic effects, enabling targeted treatment of the skin.

[0003] In practical treatment applications, the energy from the treatment head needs to be focused within a certain depth under the skin. Exceeding this depth will result in poor treatment effects and may lead to safety accidents. The depth of energy application affects the treatment effect; therefore, to ensure treatment effectiveness, it is necessary to adjust the position of the transducer in the treatment head to regulate the depth of energy application during treatment.

[0004] Current treatment heads primarily rely on motor drives to adjust transducer positions, controlling the motor's speed or rotation time to achieve treatment at different depths. However, in home settings, users often lack professional guidance and skilled operation, making it difficult to accurately and quickly move the transducer to the desired position. This not only affects treatment effectiveness but also reduces the user experience. Utility Model Content

[0005] The main purpose of this invention is to provide a treatment head and a treatment device that aims to solve the problem that users cannot accurately and quickly move the transducer to the required position when using existing treatment heads for treatment.

[0006] To achieve the above objectives, the present invention proposes a treatment head comprising a housing assembly, a transducer, a connecting assembly, a first elastic element, and a button structure. The housing assembly has a sound-transmitting opening; the transducer generates ultrasonic energy through the sound-transmitting opening; a first end of the connecting assembly is movably connected to the housing assembly, and a second end of the connecting assembly is connected to the transducer; the connecting assembly and the housing assembly have at least two contact points with a distance different from the distance from the sound-transmitting opening; the first elastic element presses the connecting assembly against the housing assembly; the button structure is movably mounted on the housing and drives the connecting assembly to move, thereby switching between different contact points.

[0007] In one embodiment of the present invention, the connecting assembly includes a first connector, the outer periphery of which is provided with a mating block, the housing assembly includes a housing and a limiting seat, the limiting seat is installed in the housing, the first connector is rotatably disposed in the housing, the limiting seat has at least two slots of different depths, the mating block mates with different slots, and forms different abutment positions.

[0008] In one embodiment of the present invention, the limiting seat has an adjustment channel that extends through both ends, and the inner wall of the adjustment channel has at least two slots that extend along the axial direction of the adjustment channel. One end of the first connector is rotatably embedded in the adjustment channel.

[0009] In one embodiment of the present invention, the connecting assembly further includes a second connecting member, which is rotatably connected to the first connecting member and connected to the transducer. The first elastic member is used to press the second connecting member against the first connecting member to keep the mating block pressed against a slot.

[0010] In one embodiment of the present invention, the treatment head further includes a connector and a plurality of signal terminals, the plurality of signal terminals being spaced apart within the housing along the moving direction of the transducer, and the connector being mounted on the connection assembly;

[0011] The mating block is embedded in a slot, and the connecting component drives the connector to communicate with a signal terminal.

[0012] In one embodiment of the present invention, one end of the button structure is provided with at least two abutting blocks of different heights. Each abutting block is located in a slot and is used to abut against a mating block. The abutting block is used to drive the first connector to rotate.

[0013] In one embodiment of this utility model, the abutting surface of at least one of the abutting block and the mating block is an inclined surface.

[0014] In one embodiment of the present invention, the treatment head further includes a second elastic element, which is disposed between the button structure and the housing and is used to provide a restoring force after the button structure moves.

[0015] In one embodiment of this utility model, the button structure has a guide hole, the limiting seat has a protruding guide post, the guide post is movably inserted into the guide hole and is used to guide the button structure to move along the slot.

[0016] In one embodiment of the present invention, the treatment head further includes a display panel disposed on the surface of the housing assembly and used to display the position of the transducer.

[0017] This utility model also proposes a therapeutic device, which includes a therapeutic handle and a therapeutic head as described above, wherein the therapeutic handle and the therapeutic head are detachably connected.

[0018] The treatment head proposed in this utility model includes a housing assembly, a transducer, a connecting assembly, a first elastic element, and a button structure. The housing assembly forms a mounting cavity with a sound-transmitting opening and an operation window. The connecting assembly and the transducer are movably disposed within the mounting cavity.

[0033] This utility model proposes a treatment head 1.

[0034] Combination Figures 1 to 3 As shown, in one embodiment of this utility model, the treatment head 1 includes a housing 10 assembly, a transducer 20, a connecting assembly 40, a first elastic member 43, and a button structure 31. The housing 10 assembly has a sound-transmitting port 14. The transducer 20 is used to generate ultrasonic energy through the sound-transmitting port 14. The first end of the connecting assembly 40 is movably connected to the housing 10 assembly, and the second end of the connecting assembly 40 is used to connect to the transducer 20. The connecting assembly 40 and the housing 10 assembly have at least two contact points with different distances from the sound-transmitting port 14. The first elastic member 43 is used to press the connecting assembly 40 against the housing 10 assembly. The button structure 31 is movably installed on the housing 10 and is used to drive the connecting assembly 40 to move, so as to realize the switching of different contact points.

[0035] In this embodiment, the sound-transmitting port 14 refers to the channel opening for ultrasonic energy output, which can be a circular or elliptical channel. The transducer 20 is used to emit ultrasonic waves, and the connecting component 40 is a mechanical linkage mechanism that converts the pressing driving force of the button structure 31 into a mechanism for controlling the movement of the transducer 20 and adjusting the focusing depth. Specifically, it can include one or more of the following: a support structure, a rotating shaft structure, a hinge structure, etc.

[0036] The abutment position refers to the contact point of the limiting structure between the connecting component 40 and the housing 10 component. Specifically, it is a physical limiting structure formed by a boss or a groove. There can be two, three, six, eight, etc. The distance difference between each abutment position and the sound-transmitting port 14 is different. For example, it can be 0.5-2 mm, 0.5 mm, 1 mm, or 2 mm. It is understood that the above range is only to make the technical solution of this embodiment clearer and is not intended to limit the distance difference between the abutment position and the sound-transmitting port 14. The distance difference between each abutment position and the sound-transmitting port 14 can also be other values ​​or ranges.

[0037] The first elastic element 43 can be a spring, sheet metal, or other elastic element. The elastic pressure continuously applied by the first elastic element 43 keeps the connecting assembly 40 and the housing 10 assembly stably in a certain abutting position. The button structure 31 drives the connecting assembly 40 to switch between different abutting positions. The button structure 31 is an operating component that is at least partially exposed on the housing 10 assembly, specifically designed as a long slider or button structure.

[0038] Specifically, when the button is pressed, the connecting component 40 rotates around the movable fulcrum. Under the elastic pressure of the first elastic member 43, the connecting component 40 enters different grooves or slides, allowing the connecting component 40 and the housing 10 to switch different abutment positions and form a positioning. Each abutment position corresponds to a specific distance between the transducer 20 and the sound-transmitting port 14. Through the above operation, the distance between the transducer 20 and the skin contact surface can be changed. The first elastic member 43 provides elastic pressure during the switching of abutment positions. When the connecting component 40 and the housing 10 switch to another abutment position, it pushes the connecting component 40 and the housing 10 to maintain stable contact.

[0039] Compared to existing technologies, traditional motor drives require circuit boards, encoders, and reduction gear sets, resulting in complex structures and high costs. This solution eliminates the need for an electronic control system, reducing failure rates and production costs. Through this technical solution, this application achieves rapid and precise adjustment of treatment depth. Users only need to push or press the button structure 31 to switch the contact position between the connecting component 40 and the housing 10 component. Since the positions of each contact position are relatively fixed, meaning that the focusing positions of the transducer 20 and the housing 10 component are all preset positions, users do not need professional or skilled operating techniques to precisely and quickly drive the transducer 20 to the desired position using the button structure 31, improving treatment effectiveness and user experience.

[0040] Combination Figures 3 to 6 As shown, in one embodiment of the present invention, the connecting component 40 includes a first connecting member 41, and a mating block 411 is provided on the outer periphery of the first connecting member 41. The housing 10 component includes a housing 10 and a limiting seat 33. The limiting seat 33 is installed inside the housing 10. The first connecting member 41 is rotatably disposed inside the housing 10. The limiting seat 33 has at least two slots 331 of different depths. The mating block 411 mates with different slots 331 and forms different abutment positions.

[0041] In this embodiment, the first connecting member 41 refers to a rotatable component with an outer peripheral mating block 411. Specifically, it can be implemented using a ring structure with a shaft hole, and the position of the mating block 411 can be changed by rotation. The mating block 411 is a protruding structure located on the outer periphery of the first connecting member 41, specifically a trapezoidal, rectangular, or rhomboid protrusion, used to embed into the slot 331 to form a support and positioning. The limiting seat 33 is a positioning component fixed within the housing 10, specifically a metal or plastic part, with a slot 331 formed inside. The slot 331 refers to a groove structure formed within the limiting seat 33, extending axially with a gradually changing depth. Here, the axial direction is... Figure 3 In the vertical direction, that is, the up-and-down movement direction of the transducer 20, different depths of the slot 331 correspond to different abutment positions formed by the mating block 411.

[0042] The housing 10 includes an upper housing 12 and a lower housing 11, which are detachably connected, for example, by plug-in or snap-fit ​​connections, to facilitate the installation of various components within the housing 10. Additionally, a balance tube 50 is provided inside the housing 10, made of a flexible material such as silicone or rubber. An acoustic medium is provided inside the housing 10, and the transducer 20 is disposed within the acoustic medium. The balance tube 50 is located on the outer periphery of the connecting assembly 40, isolating the connecting assembly 40 from the acoustic medium. The balance tube 50 is designed to be larger in the middle and smaller at the ends; the larger size in the middle provides more pressure relief space, allowing for timely and effective release of internal pressure during transportation or user use when the acoustic medium expands and contracts due to temperature changes.

[0043] When the user operates the button structure 31, the first connector 41 is driven to rotate, causing the mating block 411 to disengage from the current slot 331 and slide into a slot 331 of a different depth. The slots 331 of different depths force the first connector 41 to undergo axial displacement relative to the housing 10, thereby changing the distance between the connecting assembly 40 and the sound-transmitting port 14. For example, when the mating block 411 is inserted into a deeper slot 331, the connecting assembly 40 as a whole moves away from the sound-transmitting port 14, the distance between the transducer 20 and the sound-transmitting port 14 increases, and the focal length of the transducer 20 is adjusted accordingly.

[0044] Combination Figure 5 and Figure 6 As shown, in one embodiment of the present invention, the limiting seat 33 has an adjustment channel 333 that extends through both ends. The inner wall of the adjustment channel 333 has at least two slots 331 that extend along the axial direction of the adjustment channel 333. One end of the first connector 41 is rotatably embedded in the adjustment channel 333.

[0045] In this embodiment, the adjustment channel 333 is a cavity structure that runs through both ends of the limiting seat 33. Specifically, it can be a cylindrical or rectangular channel, which provides movement space for the rotation and axial movement of the first connector 41 and improves the stability of the first connector 41 during the adjustment process.

[0046] The slot 331 is formed on the inner wall of the adjustment channel 333, and its extension direction is parallel to the axis of the adjustment channel 333. It is used to constrain the movement path of the mating block 411 so that the mating block 411 can form different abutment positions by mating with different slots 331.

[0047] One end of the first connector 41 is embedded in the adjustment channel 333. Specifically, it can be a shaft hole mating structure to realize the rotation of the first connector 41. The adjustment channel 333 limits the radial offset of the first connector 41 and maintains the consistency of the rotation axis of the first connector 41, thus preventing the transducer 20 from deflecting during the position switching process.

[0048] Combination Figure 3 As shown, in one embodiment of the present invention, the connecting component 40 further includes a second connecting member 42, which is rotatably connected to the first connecting member 41 and connected to the transducer 20. The first elastic member 43 is used to press the second connecting member 42 against the first connecting member 41 to keep the mating block 411 pressed against a slot 331.

[0049] The second connector 42 is a component connected to the transducer 20. Specifically, it can be a connecting rod or support structure made of metal or plastic. Its function is to transmit the position adjustment action of the first connector 41 to the transducer 20, thereby adjusting the distance between the transducer 20 and the sound-permeable opening 14. A magnet 15 can be placed between the second connector 42 and the transducer 20, and connected to the transducer 20 via the magnet 15. The first elastic element 43 can be a helical spring or a disc-shaped spring, which generates axial pressure against the second connector 42 through elastic deformation, causing the mating block 411 to abut against the groove wall of the slot 331. The end face of the first connector 41 facing the sound-permeable opening 14 has a rotating hole. One end of the second connector 42 is rotatably inserted into the rotating hole, so that the second connector 42 remains relatively fixed when the first connector 41 rotates. When the first connector 41 moves axially, it drives the transducer 20 to move towards or away from the sound-permeable opening 14.

[0050] Specifically, when the user triggers the movement of the connecting component 40 via the button structure 31, the second connecting member 42, under the pressure of the first elastic member 43, drives the transducer 20 to move along a preset trajectory. The axial pressure applied by the first elastic member 43 continuously presses the mating block 411 into the slot 331 of the limiting seat 33, forming a mechanical self-locking state, thereby fixing the position of the transducer 20. When it is necessary to switch the abutting position, an external force is applied to overcome the elastic force of the first elastic member 43, causing the mating block 411 to disengage from the current slot 331. Then, the first connecting member 41 is rotated to align the mating block 411 with the next target slot 331, and the restoring force of the first elastic member 43 presses the mating block 411 into the new slot 331 again to complete the locking.

[0051] Combination Figure 3 As shown, in one embodiment of the present invention, the treatment head 1 further includes a connector 70 and a plurality of signal terminals 80. The plurality of signal terminals 80 are spaced apart in the housing 10 along the moving direction of the transducer 20. The connector 70 is installed in the connecting assembly 40. The mating block 411 is embedded in a slot 331. The connecting assembly 40 drives the connector 70 to communicate with a signal terminal 80.

[0052] The connector 70 includes a body 71, a connecting terminal 73, and a third elastic member 72. The body 71 is mounted on the connecting assembly 40. The connecting terminal 73 is movably connected to the body 71 and is communicatively connected to the signal terminal 80. The connecting terminal 73 can move relative to the body 71 in a direction toward the signal terminal 80. The third elastic member 72 is disposed between the connecting terminal 73 and the body 71 and provides a restoring force after the connecting terminal 73 moves, so that the connecting terminal 73 abuts against the signal terminal 80 and is electrically connected.

[0053] Multiple signal terminals 80 are spaced apart within the mounting cavity 13 along the moving direction of the transducer 20. The connecting assembly 40 drives the connector 70 and mating block 411 to move. As the mating block 411 sequentially switches connections with different abutment blocks 311, the connecting terminals 73 in the connector 70 sequentially switch connections with different signal terminals 80 to form test circuits. For example, when the transducer 20 moves to the first abutment position, the connecting terminal 73 contacts the first signal terminal 80, forming a closed circuit; when switched to the second abutment position, the connecting terminal 73 shifts to the position of the second signal terminal 80 and forms a closed circuit with it. Because the signal terminals 80 are spaced apart and correspond one-to-one with each abutment position, mechanical positioning and electrical signal feedback form a dual confirmation mechanism. While the user senses the abutment position switching through touch, the circuit system can instantly identify the actual position of the transducer 20 and display the current position of the transducer 20 through the display panel 60 or the main unit, thereby improving the accuracy of the user's transducer 20 position adjustment and preventing potential misjudgments of intermediate positions during continuous adjustment.

[0054] Combination Figures 5 to 7 As shown, in one embodiment of the present invention, one end of the button structure 31 is provided with at least two abutting blocks 311 of different heights. Each abutting block 311 is located in a slot 331 and is used to abut against a mating block 411. The abutting block 311 is used to drive the first connecting member 41 to rotate.

[0055] In this embodiment, the different heights of the abutment blocks 311 refer to the different protrusion dimensions of each abutment block 311 in the axial direction, such that each abutment block 311 corresponds to a specific depth position of the slot 331. When the user presses the button structure 31, the abutment blocks 311 are displaced along the axial movement path of the slot 331. Due to the height difference of each abutment block 311, when an abutment block 311 of a certain height contacts the mating block 411, the lateral thrust applied by the abutment block 311 forces the mating block 411 to move along the depth direction of the slot 331. The movement of the mating block 411 causes the first connecting member 41 to rotate around its axis, thereby changing the abutment position between the first connecting member 41 and the limiting seat 33. The depth difference of the slot 331 ensures that the mating block 411 can only stay in a preset fixed position after rotation, thereby realizing the switching of different abutment positions. The height difference of the abutting block 311 allows the pressing button structure 31 to quickly abut against the mating block 411 and drive the abutting block 311 out of the slot 331 when the mating block 411 is in the slot 331 at different depths.

[0056] Combination Figure 5 As shown, in one embodiment of the present invention, at least one of the abutting block 311 and the mating block 411 has an inclined surface as its abutting surface.

[0057] The abutting block 311 and the mating block 411 can be wedge-shaped, trapezoidal, or triangular in cross-section, with their inclined surfaces guiding the mating block 411 to produce lateral displacement. Alternatively, the abutting block 411 and the abutting block 311 can also be wedge-shaped, trapezoidal, or triangular in cross-section. Or, both ends of the abutting block 311 and the mating block 411 can be wedge-shaped, trapezoidal, or triangular in cross-section.

[0058] The contact surface is an inclined plane, which means that the relative surfaces are inclined planes. Figure 3 The vertical direction (the direction of movement of transducer 20) is an inclined planar or curved structure, and the specific inclination angle can be in the range of 5° to 80°.

[0059] Specifically, when the button structure 31 is pressed, the inclined contact area between the abutting block 311 and the mating block 411 generates an interaction force. The vertical tangential component pushes the mating block 411 to move along the axial direction of the slot 331, causing the first connecting member 41 to rotate against the elastic force of the first elastic member 43. The horizontal tangential direction pushes the mating block 411 to rotate, so that the mating block 411 disengages from the current slot 331 and rotates to the next slot 331. Then, during the reset process of the button structure 31, it slides into the next slot 331, realizing the switching of the abutting position.

[0060] Furthermore, such as Figure 6 As shown, a chamfered surface 332 is provided at the opening of the slot 331. The inclined direction of the chamfered surface 332 is towards the rotation direction of the first connector 41. Therefore, when the abutment block 311 and the mating block 411 cooperate to realize the rotation of the first connector 41, the chamfered surface 332 of the slot 331 can further improve the smoothness of the rotation of the first connector 41 and facilitate the insertion of the mating block 411 into the next slot 331.

[0061] Combination Figure 3 As shown, in one embodiment of the present invention, the treatment head 1 further includes a second elastic member 32, which is disposed between the button structure 31 and the housing 10 and is used to provide a restoring force after the button structure 31 moves.

[0062] In this embodiment, the second elastic element 32 can be a coil spring, a sheet spring, or an elastic rubber block. The second elastic element 32 is disposed between the button structure 31 and the housing 10. When the button structure 31 is pressed and moved, the restoring force of the second elastic element 32 drives the button structure 31 back to its initial position, ensuring that the button automatically returns to its original position after operation. This allows the button structure 31 to automatically reset without manual operation, thereby avoiding the risk of misoperation due to failure to reset, while reducing operation steps and improving adjustment efficiency.

[0063] The second elastic element 32 is a spring, which is sleeved on the outer periphery of the limiting seat 33, with its other end abutting against the button structure 31. The housing 10 assembly also includes a fixing seat 34, which has a limiting channel extending through both ends. The fixing seat 34 is sleeved on the outer periphery of the second elastic element 32 to provide radial limiting for the second elastic element 32. A pressure plate is provided at the end of the fixing seat 34 facing the button structure 31. When the button structure 31 is in its initial position and not pressed, the pressure plate presses against the surface of the button structure 31. When the button structure 31 is pressed, the button structure 31 moves towards the transducer 20 and separates from the pressure plate.

[0064] Combination Figure 7As shown, in one embodiment of this utility model, the button structure 31 has a guide hole 312, and the limiting seat 33 has a guide post 334 protruding from it. The guide post 334 is movably inserted into the guide hole 312 and is used to guide the button structure 31 to move along the slot 331.

[0065] In this embodiment, the guide hole 312 can be a circular, rectangular, or polygonal through hole, with its inner diameter slightly larger than the outer diameter of the guide post 334, forming a clearance fit. This structure is used to cooperate with the guide post 334 and constrain the movement trajectory of the button structure 31, preventing the button structure 31 from shifting laterally.

[0066] The guide post 334 is a protruding structure disposed on the limiting seat 33. Specifically, it can be a cylinder or prism made of metal or plastic, and its axial direction is parallel to the extension direction of the slot 331. The guide post 334 can be integrally formed with the limiting seat 33, or it can be a fixed connection structure.

[0067] When the operator presses the button structure 31, the guide post 334 slides along the inner wall of the guide hole 312, allowing the button structure 31 to move only along the axial direction of the slot 331. Since the extension direction of the slot 331 is consistent with the displacement path of the abutment block 311, the cooperation between the guide post 334 and the guide hole 312 keeps the button structure 31 in a linear motion state. During the movement, the contact surfaces between the abutment block 311 and the slot 331 remain aligned, ensuring that different abutment blocks 311 move along different slots 331, thereby driving the first connecting member 41 to complete the rotational switching.

[0068] Combination Figures 1 to 3 As shown, in one embodiment of the present invention, the treatment head 1 further includes a display panel 60, which is disposed on the surface of the housing 10 assembly and is used to display the position of the transducer 20.

[0069] In this embodiment, the display panel 60 is a visualization component installed on the outer surface of the housing 10 assembly. Specifically, it can be a liquid crystal display screen or an LED indicator array, and its display content corresponds to the real-time position of the transducer 20.

[0070] When the transducer 20 adjusts its position via the connecting component 40, its displacement data is converted into an electrical signal through the connector 70 and signal terminal 80 and transmitted to the control module of the display panel 60. The control module reflects the displacement amount through preset indicator symbols, such as a progress bar or a digital scale. When the user presses the button structure 31 to switch the contact position, the display panel 60 synchronously updates the corresponding position information of the transducer 20. The operator can directly confirm the current energy application depth by observing the display content, without relying on external measuring tools or manual calculation, thus improving the safety and operational efficiency of the treatment process.

[0071] This utility model also proposes a therapeutic device, which includes a therapeutic handle and a therapeutic head 1. The specific structure of the therapeutic head 1 is as described in the above embodiments. Since the therapeutic device adopts all the technical solutions of all the embodiments of the therapeutic head 1 described above, 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.

[0072] The treatment handle and treatment head 1 are detachably connected. Both the treatment head 1 and the treatment handle are equipped with plug-in terminals, which are used for connection. The plug-in terminals also contain electrical connectors for communication between the two. The treatment handle contains a control unit, a power module, and other components to control the energy and supply power to the treatment head 1, while also providing a comfortable grip for the user during treatment, thus improving the user experience.

[0073] 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.
