[0028] The present utility model provides an ultrasonic therapeutic apparatus 100.

[0029] Please refer to Figures 1 to 4 , an embodiment of this ultrasonic therapeutic apparatus 100 includes a liquid storage bin structure 1, a transducer assembly 2, and a driving assembly 3. The liquid storage bin structure 1 is filled with an acoustic transmission medium. The transducer assembly 2 is arranged in the liquid storage bin structure 1. The transducer assembly 2 includes a transducer bracket 21 and a transducer 22 mounted on the transducer bracket 21. The driving assembly 3 includes a movable push rod 31. The push rod 31 is in transmission connection with the transducer bracket 21 to drive the transducer assembly 2 to move. The transducer bracket 21 is provided with water-permeable holes 211. The water-permeable holes 211 are arranged at intervals in the length direction of the transducer bracket 21, and the axial direction of the water-permeable holes 211 is parallel to the moving direction of the transducer bracket 21.

[0030] It should be noted that the ultrasonic therapeutic device 100 also includes a therapeutic handle (not marked) and a therapeutic head (not marked) installed at one end of the therapeutic handle. The axis of the therapeutic handle is arranged along the first direction, and the axis of the therapeutic head is arranged along the second direction, and the first direction and the second direction are arranged crosswise, so that the overall shape of the ultrasonic therapeutic device 100 presents a "pistol" shape, which is convenient for the operator to hold and use. Then, the liquid storage tank structure 1 is arranged in the therapeutic head, the transducer assembly 2 is immersed in the liquid storage tank structure 1, and the driving assembly 3 is arranged in the therapeutic handle. The therapeutic head has a therapeutic surface for fitting with the skin, and a sound-transmitting membrane is attached to the therapeutic surface. The transducer assembly 2 includes a transducer bracket 21 and a transducer 22 installed on the transducer bracket 21. The transducer 22 is used to emit ultrasonic waves toward the sound-transmitting membrane. The ultrasonic waves are transmitted to the sound-transmitting membrane through the sound-conducting medium and then act on the skin tissue, thereby achieving a therapeutic effect. The driving assembly 3 includes a push rod 31 and a motor (not shown) for driving the push rod 31 to move. The transducer bracket 21 is arranged between the transducer 22 and the push rod 31 to drive the transducer 22 and the push rod 31, and the length direction of the transducer bracket 21 is parallel to the axial direction of the treatment head and perpendicular to the axial direction of the push rod 31. In the embodiment shown in the figure, the motor is a linear motor. The axial movement of the motor driving the push rod 31 will drive the transducer bracket 21 and the transducer 22 to make linear reciprocating motion (lateral motion), thereby adjusting the treatment area. At this time, the axial direction of the water-permeable hole 211 is parallel to the direction of the lateral movement of the transducer bracket 21. In other embodiments, the motor can be a rotary motor, and the motor will drive the push rod 31 to rotate. At this time, a transmission mechanism can be arranged between the push rod 31 and the transducer bracket 21, such as a worm and gear meshing mechanism, which can convert the rotational motion of the push rod 31 into the linear motion (longitudinal motion) of the transducer bracket 21, thereby adjusting the treatment depth of the transducer 22. At this time, the axial direction of the water permeable hole 211 is parallel to the longitudinal movement direction of the transducer bracket 21 .

[0031] Since the liquid storage tank structure 1 is filled with liquid sound-conducting medium, the transducer bracket 21 will inevitably need to overcome liquid resistance during the reciprocating movement. When the liquid resistance is too large, a jamming phenomenon will occur. For this reason, the ultrasonic therapeutic device 100 is provided with water-permeable holes 211 on the transducer bracket 21. The water-permeable holes 211 are evenly spaced in the length direction of the transducer bracket 21, and the axial direction of the water-permeable holes 22 is arranged parallel to the moving direction of the transducer bracket 21. The water-permeable holes 211 can be circular holes, square holes or other shapes, which are not limited here. The setting of the water-permeable holes 211 can reduce the direct impact area between the sound-conducting medium and the transducer bracket 21, thereby reducing the movement resistance and avoiding the jamming problem of the transducer bracket 21 during the movement.

[0032] Reference Figure 2 , Figure 3 or Figure 4, in an embodiment of the present utility model, the transducer bracket 21 includes a vertical portion 212 and transverse portions 213 protruding from both sides of the vertical portion 212. The vertical portion 212 is used for drivingly connecting the transducer 22 and the push rod 31. The water-permeable holes 211 are arranged at intervals in the length direction of the vertical portion 212. Wherein, the transverse portions 213 can be hollowly connected to the vertical portion 212 through connecting ribs 215, so as to allow the sound guiding medium to pass through the hollow area between the water-permeable holes 211 and the connecting ribs 215, reduce the impact area, and reduce the movement resistance. Moreover, guide rods 4 are respectively inserted through the two transverse portions 213, and the extending direction of the guide rods 4 is consistent with the movement direction of the transducer assembly 2. The transducer bracket 21 stably moves under the guiding action of the two guide rods 4, and the problem that the transducer bracket 21 shakes during the movement can be avoided.

[0033] Further, the vertical portion 212 may include a first bent section 2121, a second bent section 2122, and a third bent section 2123 that are sequentially arranged from top to bottom and are in a semi-cylindrical shape. The first bent section 2121 and the third bent section 2123 are arched towards the first direction, the second bent section 2122 is arched towards the second direction, and the first direction and the second direction are the forward direction and the backward direction of the transducer bracket 21 respectively. Wherein, the forward direction of the transducer bracket 21 is the direction from the stroke starting point to the stroke ending point, and the backward direction is the direction from the stroke ending point to the stroke starting point. Moreover, the first bent section 2121, the second bent section 2122, and the third bent section 2123 are sequentially disconnected, so that a first water passing opening 2124 is formed at the connection between the first bent section 2121 and the second bent section 2122, and a second water passing opening 2125 is formed at the connection between the second bent section 2122 and the third bent section 2123. At this time, the water-permeable holes 211 are arranged at the most convex points of the first bent section 2121, the second bent section 2122, and the third bent section 2123.

[0034] In this embodiment, the water-permeable holes 211 are arranged at the most convex points of the bent sections, which not only enables the sound guiding medium directly impacting the transducer bracket 21 to pass through the water-permeable holes 211 more concentratedly, but also enables the turbulent flow formed by the impact between the transducer brackets 21 to flow through the water passing openings, further reducing the water flow resistance. In addition, the first bent section 2121 and the third bent section 2123 are arched towards the forward direction of the transducer bracket 21, and the second bent section 2122 is arched towards the backward direction, which can ensure that the transducer bracket 21 will not be subjected to a large water flow resistance during both the forward and backward processes.

[0035] Refer to Figure 1 and Figure 2, the ultrasonic therapeutic apparatus 100 further includes a first telescopic tube 5 and a second telescopic tube 6. The first telescopic tube 5 is disposed on the side of the transducer support 21 away from the driving assembly 3, and the second telescopic tube 6 is disposed on the side of the transducer support 21 facing the driving assembly 3. The first telescopic tube 5 and the second telescopic tube 6 are telescoped under the traction of the transducer support 21 to buffer the resistance generated by the perturbation of the acoustic medium.

[0036] To realize the connection between the first telescopic tube 5 and the second telescopic tube 6 and the transducer support 21, the transducer support 21 further includes a sleeve 214. The sleeve 214 is disposed at one end of the vertical portion 212 away from the transducer 22. A connecting rib 215 is provided between the sleeve 214 and the vertical portion 212 to connect the sleeve 214 and the vertical portion 212 in a hollowed-out manner, and the acoustic medium can flow through the hollowed-out area between the water-permeable holes 211 and the connecting rib 215. One ends of the first telescopic tube 5 and the second telescopic tube 6 facing the transducer support 21 are both connected to the sleeve 214.

[0037] The surfaces of the first telescopic tube 5 and the second telescopic tube 6 are formed into corrugations or folds. When the acoustic medium generates large fluctuations, the telescopic tubes can be squeezed, causing the volume of the telescopic tubes to change, thereby absorbing and buffering the water pressure and preventing the sound-transmitting membrane from bulging under the action of the water pressure.

[0038] At this time, the connection node between the push rod 31 and the transducer support 21 is preferably disposed inside the telescopic tube, so as to prevent the connection node from being immersed in the acoustic medium and causing rust. For this purpose, a chassis 216 is provided inside the sleeve 214, and the push rod 31 is inserted into the first telescopic tube 5 or the second telescopic tube 6 to be in transmission connection with the chassis 216.

[0039] Meanwhile, ventilation holes 2161 are formed in the chassis 216 to communicate the first telescopic tube 5 and the second telescopic tube 6, thereby preventing the problem of jamming caused by the generation of pressure difference during the movement of the chassis 216 in the first telescopic tube 5 and the second telescopic tube 6.

[0040] Refer to Figure 1 , in the ultrasonic therapeutic apparatus 100 of the present invention, the driving assembly 3 further includes an auxiliary rod 32. The auxiliary rod 32 is disposed inside the first telescopic tube 5 or the second telescopic tube 6. One end of the auxiliary rod 32 is fixedly connected to the chassis 216, and the other end of the auxiliary rod 32 is fixedly connected to the push rod 31, that is, the push rod 31 is connected to the transducer support 21 through the auxiliary rod 32. During assembly, the transducer 22, the transducer support 21, the first telescopic tube 5, the second telescopic tube 6, and the auxiliary rod 32 are first assembled as shown in Figure 2The whole shown is then placed into the liquid storage chamber structure 1. Finally, the push rod 31 is inserted into the liquid storage chamber structure 1 to be fixedly connected to the auxiliary rod 32, thereby realizing the assembly of the internal parts of the ultrasonic therapeutic apparatus 100. At this time, when the motor drives the axial movement of the push rod 31, it will drive the auxiliary rod 32 to reciprocate, thereby driving the transducer bracket 21 and the transducer 22 to reciprocate.

[0041] Referring to Figure 1 , a jack is provided on the side wall of the liquid storage chamber structure 1, and a bearing 7 is arranged in the jack. The push rod 31 passes through the central hole of the bearing 7 to be in transmission connection with the transducer bracket 21. The inner peripheral wall of the bearing 7 is attached to the peripheral side wall of the push rod 31. The precise fit between the push rod 31 and the bearing 7 can ensure the stability of the movement of the transducer assembly. However, at this time, the fitting clearance between the push rod 31 and the bearing 7 is very small, and the gas inhaled during the movement of the telescopic tube is difficult to discharge, which will cause the volume of the telescopic tube to expand. This volume change transmitted to the sound-transmitting membrane may cause the sound-transmitting membrane to bulge. For this reason, in an embodiment of the ultrasonic therapeutic apparatus 100, an air-permeable groove 71 is locally recessed on the inner peripheral wall of the bearing 7 to communicate the chamber inside the telescopic tube and the chamber outside the telescopic tube, as shown in Figure 5 . The provision of the air-permeable groove 71 enables the gas inside the telescopic tube to be discharged smoothly, avoiding the problem of the sound-transmitting membrane bulging caused by the expansion of the telescopic tube.

[0042] At the same time, a sealing ring 8 is sleeved on the bearing 7. The sealing ring 8 is located at the connection between the bearing 7 and the liquid storage chamber structure 1 to prevent the leakage of the sound guiding medium.

[0043] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
