[0025] The following will disclose multiple embodiments of the present invention with drawings. For the purpose of clear description, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not necessary. In addition, for the purpose of simplifying the drawings, some conventional structures and components will be depicted in a simple schematic manner in the drawings.
[0026] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
[0027] Combination Figures 1 to 4As shown, an ultrasonic treatment device with adjustable focal depth of the present invention comprises a handle 100 and a treatment head 200, and the handle 100 and the treatment head 200 are detachably connected. The handle 100 comprises a housing 1, a control panel 2 and a driving assembly 3, the housing 1 is provided with an installation cavity 10, and the control panel 2 and the driving assembly 3 are both arranged in the installation cavity 10. The control panel 2 is electrically connected to the driving assembly 3, and the control panel 2 is used to control the operation of the driving assembly 3.
[0028] The treatment head 200 includes a shell 4, a cover 5 and a transducer 6. The shell 4 is provided with a receiving cavity 40. The transducer 6 is arranged in the receiving cavity 40. The shell 4 is provided with a mounting port 41 at one end close to the handle 100, and a sound-transmitting port 42 at the other end. The cover 5 is sealed on the mounting port 41, and the sound-transmitting port 42 is sealed and covered with a sound-transmitting membrane 43, so that the receiving cavity 40 forms a sealed cavity, which is conducive to filling the conducting liquid in the receiving cavity 40. The sound-emitting surface of the transducer 6 faces the sound-transmitting port 42, ensuring that the ultrasonic energy emitted by the transducer 6 is emitted facing the sound-transmitting port 42, thereby improving the treatment effect.
[0029] The driving assembly 3 is provided with a driving rod 32 capable of outputting a linear displacement, and the cover body 5 is provided with a driving hole 51, through which the driving rod 32 is sealed and passes through the driving hole 51 to be detachably connected to the transducer 6 by magnetic attraction. The driving assembly 3 can make the driving rod 32 output a linear displacement, thereby driving the transducer 6 to perform a reciprocating linear motion, and then the focal position of the transducer 6 can be adjusted, thereby achieving the purpose of adjustable focal depth.
[0030] Furthermore, since the driving rod 32 of the driving assembly 3 in the handle 100 is detachably connected to the transducer 6 in the treatment head 200 by magnetic attraction, the driving rod 32 can be quickly connected to or disconnected from the transducer 6 when the treatment head 200 and the handle 100 are assembled and disassembled, thereby improving the convenience of assembling and disassembling the treatment head 200 and the handle 100. When the treatment head 200 or the handle 100 is damaged, it can be replaced in time, thereby avoiding the entire ultrasonic treatment device from being scrapped and minimizing the loss.
[0031] A boss 52 is provided on the end surface of the cover 5 close to the transducer 6, and the driving hole 51 passes through the boss 52. A waterproof telescopic capsule 7 is provided in the accommodating cavity 40, and the waterproof telescopic capsule 7 is sleeved on the boss 52 to seal the driving hole 51 to prevent the conductive liquid from flowing out of the driving hole 51. The portion of the driving rod 32 extending into the accommodating cavity 40 is arranged in the waterproof telescopic capsule 7, and the waterproof telescopic capsule 7 wraps the driving rod 32 to prevent the conductive liquid from contacting the driving rod 32.
[0032] A first magnetic body is provided at a position corresponding to the transducer 6 and the driving rod 32. Since the driving rod 32 is made of ferromagnetic material and can be attracted by the first magnetic body, the driving rod 32 and the transducer 6 can be detachably connected by magnetic attraction through the first magnetic body.
[0033] Alternatively, a second magnetic body 33 is provided at the end of the driving rod 32 , a third magnetic body 65 is provided at a position corresponding to the transducer 6 and the driving rod 32 , and the driving rod 32 and the transducer 6 are magnetically connected via the second magnetic body 33 and the third magnetic body 65 .
[0034] Combination Figure 3 and Figure 4 As shown, the end face of the cover 5 facing away from the shell 4 is provided with a rotation buckle 53, and the end face of the shell 1 close to the treatment head 200 is provided with a rotation slot 11 corresponding to the position of the rotation buckle 53, and the rotation buckle 53 is correspondingly inserted into the rotation slot 11 to achieve rotational connection.
[0035] Specifically, the rotating buckle 53 includes a clamping arm 531 and a clamping block 532 . The clamping block 532 is arranged on the side of the free end of the clamping arm 531 , so that a certain distance is set between the clamping block 532 and the end surface of the treatment head 200 . The shape of the rotating slot 11 is an arc, and the center of the rotating slot 11 coincides with the rotation axis of the driving rod 32. The rotating slot 11 includes a storage slot 111 and a limit block 112 arranged in the storage slot 111. The limit block 112 is connected to a long side wall of the storage slot 111. The gap between the limit block 112 and one end side wall of the storage slot 111 forms an insertion port 113 for the clamping arm 531 to be inserted into the storage slot 111. The gap between the limit block 112 and the other long side wall of the storage slot 111 forms a guide groove 114 when the clamping arm 531 rotates. The gap between the limit block 112 and the bottom wall of the storage slot 111 forms a storage portion 115 for storing the clamping block 532.
[0036] When the treatment head 200 is rotationally engaged with the handle 100, the engaging arm 531 of the rotating buckle 53 is first inserted into the receiving slot 111 from the insertion port 113 of the rotating slot 11, and then the treatment head 200 starts to rotate. During the rotation, the engaging arm 531 moves along the guide slot 114, so that the engaging block 532 slides smoothly into the receiving portion 115, thereby realizing the rotational engagement of the treatment head 200 with the handle 100.
[0037] When the treatment head 200 and the handle 100 are rotated and disassembled, the treatment head 200 is rotated in the opposite direction, so that the clamping arm 531 moves in the opposite direction along the guide groove 114, and the clamping block 532 leaves the storage portion 115 until the clamping arm 531 of the rotating buckle 53 moves into the insertion port 113. At this time, the clamping arm 531 can be pulled out from the insertion port 113, thereby realizing the disassembly and separation of the treatment head 200 and the handle 100.
[0038] The end face of the cover 5 facing away from the shell 4 is also provided with an anti-fool protrusion 54, and the end face of the shell 1 close to the treatment head 200 is also provided with an anti-fool groove 12. Only when the anti-fool protrusion 54 is correspondingly inserted into the anti-fool groove 12, the rotating buckle 53 can be correspondingly inserted into the rotating card slot 11 to achieve rotational engagement. The anti-fool protrusion 54 is arranged to correspond with the anti-fool groove 12 to ensure the correct combination of the treatment head 200 and the handle 100, and to ensure that the electrical connection line of the control board 2 in the handle 100 and the electrical connection line in the treatment head 200 can be correctly connected.
[0039] An adapter plate 13 is provided at one end of the shell 1 close to the treatment head 200, and the adapter plate 13 blocks the installation cavity 10 of the shell 1. A through hole 131 is provided in the middle of the adapter plate 13, and the driving rod 32 passes through the through hole 131. The rotating slot 11 and the anti-fool groove 12 are both arranged on the adapter plate 13.

When the transducer 6 reciprocates in a straight line, the guide shaft 45 guides the transducer 6 to ensure the stability of the transducer 6 and improve the treatment effect.
[0041] like Figure 1 and Figure 3 As shown, the transducer 6 includes a mounting frame 61 and a transducer unit 63, the guide sleeve 62 is arranged on the outer wall of the mounting frame 61, a connecting groove is provided on the side of the mounting frame 61 close to the sound-permeable port 42, the transducer unit 63 is embedded in the connecting groove, a connecting portion 64 is provided on the side of the mounting frame 61 close to the cover body 5, and the first magnetic body or the third magnetic body 65 is arranged on the connecting portion 64.
[0042] There are two guide shafts 45, which are respectively distributed on both sides of the transducer 6. Two fixing holes 46 are correspondingly provided on the mounting seat 44. One end of the two guide shafts 45 is respectively inserted into the fixing holes 46. The cover body 5 is provided with mounting holes 55 and fault-tolerant mounting holes 56 at positions corresponding to the two fixing holes 46. The diameter of the fault-tolerant mounting hole 56 is larger than the diameter of the mounting hole 55. The other ends of the two guide shafts 45 are respectively inserted into the mounting holes 55 and the fault-tolerant mounting holes 56. The fault-tolerant mounting holes 56 can absorb the error when the guide rod 45 is assembled with the cover body 5 and the mounting seat 44, so that the cover body 5 can be smoothly assembled and combined with the housing 4.
[0043] The driving assembly 3 includes a screw motor 31, and a driving rod 32 is disposed in the screw motor 31. The driving assembly 3 may also include a linear motor, and the driving rod 32 is disposed in the linear motor.

The driving rod 32 can drive the sensing device 81 to move linearly, so that the sensing device 81 passes through the starting switch 82 and the end switch 83 respectively. The distance between the starting switch 82 and the end switch 83 is the stroke of the focus movement of the transducer 6, and the precise control of the focus movement stroke of the transducer 6 can be achieved.
