Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic therapy, in particular to an ultrasonic therapy instrument. Background Art

[0002] Existing home ultrasonic therapy products mainly include a handle and a treatment head. The transducer in the treatment head is the core component for generating ultrasonic waves and has a limited service life. In order to reduce the cost of use for users, some products adopt a technical solution that the treatment head and the handle are detachably connected. A guide surface and a guide ridge are set at the connection between the output shaft of the handle and the input shaft of the treatment head. The cooperation of the guide surface and the guide ridge enables the output shaft of the handle to drive the rotation of the transducer assembly of the treatment head.

[0003] However, the output end of the handle cannot rotate freely due to the action of the reduction box mechanism, while the input end of the treatment head is subject to the torque of the focusing mechanism, which also produces a certain rotational resistance. When the treatment head needs to be replaced, the treatment head is docked with the handle. At this time, the guide surface of the handle output shaft and the guide ridge of the treatment head input shaft may be misaligned. Since the output shaft is subject to the resistance of the handle reduction box and the input shaft is subject to the resistance of the treatment head focusing mechanism, it is difficult for the handle and the treatment head to dock and the connection is not smooth. When the user is docking, he may need to apply additional torque, which not only increases the difficulty of operation, but may also cause damage to the reduction box mechanism of the handle and the automatic focusing mechanism of the treatment head.

[0007] A treatment head, the treatment head is detachably connected to the handle, the treatment head comprises a transducer assembly and a first adapter, the first adapter is rotatably connected to the transducer assembly, and the first adapter is used to rotate around the first direction to drive the transducer assembly to move along the first direction;

[0008] a second adapter, the second adapter is rotatably connected to the first adapter, and the docking member can drive the second adapter to rotate relative to the first adapter within a first preset range;

[0009] Wherein, the docking member is suitable for driving the transducer assembly to move along the first direction through the first adapter and the second adapter.

[0010] In one embodiment of the utility model, a limiting portion is provided on the end face of the second adapter, and a stopping portion is provided on the end face of the first adapter. When the docking member drives the second adapter to rotate beyond the first preset range, the limiting portion abuts against the stopping portion, so that the second adapter drives the first adapter to rotate.

[0011] In one embodiment of the utility model, the docking member is provided with an inserting end, and the second adapter is provided with an inserting slot. When the inserting end is inserted into the inserting slot, the docking member presses and drives the second adapter to rotate relative to the docking member within a second preset range.

[0012] In an embodiment of the present invention, the maximum rotation angle of the second adapter relative to the docking member within the second preset range is smaller than the rotation angle of the second adapter relative to the first adapter within the first preset range.

[0013] In an embodiment of the present invention, the maximum rotation angle of the second adapter relative to the docking member within the second preset range is 90 degrees.

[0014] In an embodiment of the present invention, a rotation angle of the second adapter relative to the first adapter within the first preset range is 120 degrees.

[0015] In one embodiment of the utility model, a guide portion is convexly provided on the outer side surface of the plug end, a guide groove is provided on the inner wall of the second adapter, the guide portion and the guide groove are matched, and the surface of the guide portion is a curved surface;

[0016] When the plug-in end is inserted into the plug-in slot, the guide portion can press and drive the second adapter to rotate relative to the docking member, so that the plug-in end and the plug-in slot are aligned up and down.

[0017] In one embodiment of the utility model, at least two guide portions are provided, the number of the guide portions matches the number of the guide grooves, and the guide portions are arranged adjacent to each other in sequence along the rotation direction of the docking member;

[0019] In one embodiment of the utility model, the transducer assembly includes a transducer and a lifting rod, one end of the lifting rod is connected to the transducer, and the other end is drivingly connected to the first adapter, and the first adapter rotates to drive the lifting rod to drive the transducer to move along the first direction.

[0020] In an embodiment of the present invention, the first adapter is provided with a threaded hole extending along its axial direction, and the other end of the lifting rod is disposed in the threaded hole and is threadedly connected to the first adapter.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0036] The utility model provides an ultrasonic therapeutic apparatus 1.

[0037] Combination Figure 1-Figure 5 As shown, in one embodiment of the utility model, the ultrasonic therapeutic apparatus 1 includes a handle 10, a treatment head 20 and a second adapter 30; the handle 10 includes a docking member 12, and the docking member 12 is suitable for rotating around a first direction; the treatment head 20 is detachably connected to the handle 10, and the treatment head 20 includes a transducer assembly 21 and a first adapter 22, the first adapter 22 is rotatably connected to the transducer assembly 21, and the first adapter 22 is used to rotate around the first direction to drive the transducer assembly 21 to move along the first direction; the second adapter 30 is rotatably connected to the first adapter 22, and the docking member 12 can drive the second adapter 30 to rotate relative to the first adapter 22 within a first preset range; wherein, the docking member 12 is suitable for driving the transducer assembly 21 to move along the first direction through the first adapter 22 and the second adapter 30.

[0038] In this embodiment, a driving mechanism 11 is disposed inside the handle 10, and a power output shaft of the driving mechanism 11 is drivingly connected to the docking member 12 to drive the docking member 12 to rotate. Figure 4 The circumferential direction of the docking piece 12. The handle 10 and the treatment head 20 are detachably connected to facilitate the replacement of the treatment head 20. The detachable connection can be a plug connection, a threaded connection, or a clamping connection.

[0039] The treatment head 20 includes a housing 23, a transducer assembly 21 and a first adapter 22 disposed in the housing 23, wherein the transducer assembly 21 is used to emit ultrasonic waves, and achieves cosmetic treatment of the skin by focusing the ultrasonic waves under the skin. The first adapter 22 can drive the transducer assembly 21 to move along a first direction, so that under the drive of the driving structure, the transducer 211 can move in a vertical direction, thereby achieving the focus adjustment of the transducer 211, so that the ultrasonic therapeutic device 1 can be used for treatment at different depths under the skin.

[0040] At the same time, the present application also provides a second adapter 30, which is provided between the first adapter 22 and the docking member 12, and the second adapter 30 can rotate relative to the first adapter 22, and can also rotate relative to the docking member 12. Therefore, when the handle 10 and the treatment head 20 are assembled or the treatment head 20 is replaced, the connection position of the handle 10 and the treatment head 20 is first aligned up and down, and then the handle 10 and the treatment head 20 are docked and connected. At this time, the docking member 12 is also docked and connected with the second adapter 30 in theory.

[0041] When the docking member 12 and the second adapter 30 may be misaligned, the docking member 12 drives the second adapter 30 to rotate relative to the docking member 12 to adjust the second adapter 30 to be aligned with the docking member 12, and the treatment head 20 and the handle 10 are now docked. When the transducer 211 needs to be rotated to adjust the focal length, the driving mechanism 11 drives the docking member 12 to rotate, so as to drive the second adapter 30 to rotate. When the second adapter 30 rotates beyond the first preset range, the second adapter 30 abuts against the first adapter 22. At this time, the second rotating member continues to rotate, which can drive the first adapter 22 and the transducer 211 to rotate, thereby adjusting the focal length of the transducer 211. The first preset range is the maximum rotation angle of the second adapter 30 relative to the first adapter 22.

[0042] The present application solves the problem that the handle 10 and the treatment head 20 of existing ultrasonic treatment products are difficult to dock and the connection is not smooth, reduces the difficulty of operation when connecting the handle 10 and the treatment head 20, and the risk of components being easily damaged when the handle 10 and the treatment head 20 are docked, thereby improving the user experience.

[0043] Combination Figure 5 As shown, in one embodiment of the present invention, a limit portion 33 is provided on the end surface of the second adapter 30, and a stop portion 221 is provided on the end surface of the first adapter 22. When the docking member 12 drives the second adapter 30 to rotate beyond the first preset range, the limit portion 33 abuts against the stop portion 221, so that the second adapter 30 drives the first adapter 22 to rotate.

[0044] In this embodiment, the cross-sectional shape of the stopper 221 can be a rectangle, a rhombus, a triangle, etc., and it protrudes on the end face of the first adapter 22. The cross-sectional shape of the limiter 33 can be a fan-shaped, a rectangle, etc., and the height protruding from the second adapter 30 is the same or similar to the height of the stopper 221. Therefore, when the first adapter 22 and the second adapter 30 are assembled, the stopper 221 abuts against the end face of the second adapter 30, the limiter 33 abuts against the end face of the first adapter 22, and the stopper 221 and the limiter 33 are spaced apart. When the treatment head 20 and the handle 10 are docked, the docking member 12 drives the second adapter 30 to rotate so that the limiter 33 approaches the stopper 221. When the second adapter 30 rotates to the first preset range, the limit portion 33 rotates to abut against the stop portion 221. At this time, the second rotating member can be rotated continuously to drive the first rotating member to rotate, so as to achieve the function of adjusting the focus of the transducer 211. It can be understood that the limit portion 33 and the stop portion 221 are in surface contact when they abut, and the shapes of the two are adapted, thereby improving the stability of the second rotating member driving the first rotating member to rotate.

[0045] Combination Figure 3 As shown, in one embodiment of the present invention, the docking member 12 is provided with an inserting end 121, and the second adapter 30 is provided with an inserting slot 31. When the inserting end 121 is inserted into the inserting slot 31, the docking member 12 presses and drives the second adapter 30 to rotate relative to the docking member 12 within a second preset range.

[0046] In this embodiment, the docking member 12 and the second rotating member are plug-in connected, and the plug-in slot 31 of the second adapter 30 is matched with the plug-in end 121 of the docking member 12 in shape. The plug-in end 121 and the plug-in slot 31 include a plurality of mating surfaces of different or same shapes, such as a plane, an inclined surface, and a curved surface, so that the docking member 12 and the second adapter 30 need to be aligned up and down before the plug-in end 121 can be inserted into the plug-in slot 31. When the docking member 12 and the second adapter 30 are not aligned, when the plug-in end 121 is inserted into the plug-in slot 31, the plug-in end 121 will squeeze the slot wall of the plug-in slot 31 to drive the second rotating member to rotate to a state where the plug-in slot 31 and the plug-in end 121 are aligned up and down. Therefore, when replacing and disassembling the treatment head 20, even if there is a deviation between the docking member 12 and the second adapter 30, the treatment head 20 and the handle 10 can be smoothly docked and connected, which improves the convenience of assembly of the two. The second preset range is the maximum rotation angle of the second rotating member relative to the docking member 12 when driven by the docking member 12. This angle is related to the shape and size of the plug-in end 121 and the plug-in slot 31. Therefore, the second preset range can be changed by changing the shape or size of the plug-in end 121 and the plug-in slot 31.

[0047] In one embodiment of the present invention, the maximum rotation angle of the second adapter 30 relative to the docking member 12 within the second preset range is smaller than the rotation angle of the second adapter 30 relative to the first adapter 22 within the first preset range.

[0048] When the treatment head 20 and the handle 10 are not aligned, the docking member 12 is required to drive the second rotating member to rotate relative to the docking member 12 to adjust the alignment angle between the docking member 12 and the second adapter 30; at the same time, the focusing mechanism in the transducer assembly 21 will generate resistance to the rotation of the first adapter 22, and the reducer in the handle 10 will generate resistance to the rotation of the docking member 12.

[0049] Therefore, in this embodiment, the maximum rotation angle of the second adapter 30 relative to the docking member 12 within the second preset range is designed to be smaller than the rotation angle of the second adapter 30 relative to the first adapter 22 within the first preset range, so that when adjusting the alignment angle of the docking member 12 and the second adapter 30, the second adapter 30 can rotate freely relative to both the first adapter 22 and the docking member 12 without being subject to resistance from the focusing mechanism or the reducer, thereby ensuring the service life of the focusing mechanism and the reducer.

[0050] In one embodiment of the present invention, the maximum rotation angle of the second adapter 30 relative to the docking member 12 within the second preset range is 90 degrees. That is, when the handle 10 and the treatment head 20 are docked, even if there is a deviation between the plug end 121 and the plug slot 31, the plug end 121 and the plug slot 31 can be docked when the second rotating member rotates less than or equal to 90 degrees. It can be understood that, as in the above embodiment, the plug end 121 and the plug slot 31 have multiple mating surfaces, four identical mating surfaces can be set, and each mating surface is evenly arranged adjacent to each other, so that the maximum rotation angle of the second adapter 30 relative to the docking member 12 within the second preset range is 90 degrees.

[0051] In other embodiments, the plug end 121 and the plug slot 31 may be designed to have three or five identical mating surfaces, so that the maximum rotation angle of the second adapter 30 relative to the docking member 12 within the second preset range is 120 degrees or 36 degrees. The shapes and sizes of the multiple mating surfaces may also be designed to be different.

[0052] In an embodiment of the present invention, the rotation angle of the second adapter 30 relative to the first adapter 22 within the first preset range is 120 degrees.

[0053] It can be known from the above embodiment that when the second adapter 30 rotates relative to the first adapter 22, it is limited and stopped by the stopper 221 and the limiting portion 33. Therefore, the stopper 221 and the limiting portion 33 can be designed to have different arcs to achieve different rotation angles. In this embodiment, the stopper 221 extends from the edge of the first adapter 22 to the center of the first adapter 22, or extends from the edge of the first adapter 22 to the edge of the other side opposite to the first adapter 22, that is, a centrally symmetrical structure is formed, and the limiting portion 33 is also the same. At the same time, the limiting portion 33 is adapted to the contact surface of the stopper 221 to increase the limited contact area between the limiting portion 33 and the stopper 221, thereby improving the stability of the second adapter 30 driving the first adapter 22 to rotate.

[0054] In other embodiments, the rotation angle of the second adapter 30 relative to the first adapter 22 within the first preset range may also be 140 degrees, 160 degrees, etc.

[0055] Combination Figures 3 to 5 As shown, in one embodiment of the present utility model, a guide portion 122 is convexly provided on the outer side surface of the plug end 121, and a guide groove 32 is provided on the inner wall of the second adapter 30, the guide portion 122 and the guide groove 32 are matched, and the surface of the guide portion 122 is a curved surface;

[0056] When the plug end 121 is inserted into the plug slot 31 , the guide portion 122 can press and drive the second adapter 30 to rotate relative to the docking member 12 , so that the plug end 121 and the plug slot 31 are aligned vertically.

[0057] In this embodiment, the raised guide portion 122 cooperates with the guide groove 32. Since the surface of the guide portion 122 is a curved surface, when the plug-in end 121 is inserted into the plug-in groove 31, the guide portion 122 plays a guiding role. At the same time, when the docking member 12 and the second adapter 30 are misaligned, the guide portion 122 presses against the groove wall of the guide groove 32 and drives the second adapter 30 to rotate.

[0058] Combination Figures 3 to 5 As shown, in one embodiment of the present utility model, at least two guide portions 122 are provided, the number of the guide portions 122 matches the number of the guide grooves 32, and both are arranged adjacent to each other in sequence along the rotation direction of the docking member 12;

[0059] And / or, the plug end 121 and the guide portion 122 are both in a contracted shape along the direction from the handle 10 to the treatment head 20 .

[0060] The number of guide portions 122 can be two, three, four, etc., and is not limited here. In this embodiment, the number of guide portions 122 is four, and the number of guide slots 32 is also four. The four guide portions 122 and guide slots 32 have the same shape and size, and are arranged adjacent to each other. Therefore, no matter what the rotation misalignment angle between the docking member 12 and the second adapter 30 is, when the plug end 121 is inserted into the plug slot 31, each guide portion 122 is rotationally connected to a guide slot 32, and together drives the second adapter 30 to rotate, thereby improving the convenience of the docking member 12 and the second adapter 30 when rotating and matching. In other embodiments, three or five guide portions 122 and guide slots 32 may also be provided.

[0061] When the number of the guide portion 122 and the guide groove 32 is limited or not limited, the plug end 121 and the guide portion 122 are designed to be contracted along the direction from the handle 10 to the treatment head 20. Since the plug groove 31 and the guide groove 32 are respectively adapted to the plug end 121 and the guide portion 122, their shapes are also the same. When the plug end 121 is inserted into the plug groove 31, the end size of the plug end 121 is small, so that the plug end 121 can be smoothly inserted into the plug groove 31 at different angles. As the plug end 121 continues to be inserted into the plug groove 31, the plug end 121 abuts against the groove wall of the plug groove 31. Since the cross-sectional dimensions of the plug end 121 and the guide portion 122 continue to increase, the second rotating member is better driven to rotate. It can be understood that when there are 4 guide portions 122, the shape of the plug end 121 is plum blossom-shaped, and the plug end 121 and the plug groove 31 have a higher rotation connection stability.

[0062] Combination Figure 3 As shown, in one embodiment of the utility model, the transducer assembly 21 includes a transducer 211 and a lifting rod 212, one end of the lifting rod 212 is connected to the transducer 211, and the other end is drivingly connected to the first adapter 22. The first adapter 22 rotates to drive the lifting rod 212 to drive the transducer 211 to move along the first direction.

[0063] In this embodiment, the transducer 211 is used to generate ultrasonic waves for treating skin tissue. In order to improve the installation stability of the transducer 211, the transducer assembly 21 also includes a bearing 213, a base 214 and a mounting seat 215. One end of the lifting rod 212 is connected to the mounting seat 215. The mounting seat 215 is provided with a mounting groove at one end away from the lifting rod 212. The transducer 211 is installed in the mounting groove. According to the shape of the transducer 211, the bottom wall of the mounting groove can be designed into an arc shape, a plane shape, etc. The bearing 213 and the base 214 are arranged between the first adapter 22 and the mounting seat 215, and are arranged around the outer periphery of the lifting rod 212, playing the role of supporting and assisting the rotation of the first adapter 22 and the lifting rod 212, thereby improving the stability of the first adapter 22, the lifting rod 212, and the transducer 211 when rotating.

[0064] Combination Figure 3 As shown, in one embodiment of the present invention, the first adapter 22 is provided with a threaded hole extending along its axial direction, and the other end of the lifting rod 212 is disposed in the threaded hole and is threadedly connected to the first adapter 22 .

[0065] In this embodiment, the lifting rod 212 and the first adapter 22 are designed to be threadedly connected, wherein the first adapter 22 rotates around its own circumference when rotating, and its position in the vertical direction does not change, so that when the first adapter 22 rotates, the lifting rod 212 is driven to move in the vertical direction. In other embodiments, the first adapter 22 can also drive the lifting rod 212 and the transducer 211 to move by gear transmission.

[0066] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
