[0028] The realization of the objectives, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. Modes for Carrying Out the Invention

[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0031] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. 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 this application.

[0032] The existing ultrasonic therapeutic device's treatment handle usually includes a treatment head and a handle. The input shaft of the treatment head and the output shaft of the handle need to be manually aligned and connected, which is time-consuming and affects efficiency. Therefore, the present application provides a treatment handle that can quickly install the handle body and the treatment head.

[0033] The present application proposes a treatment handle 10, comprising a handle body 1 and a treatment head 2, the handle body 1 comprising a drive assembly 11, the drive assembly having a rotating output shaft 12, the first end of the output shaft 12 having a first guide; the treatment head 2 comprises a transducer assembly 21 and an input shaft 22, one end of the input shaft 22 is connected to the transducer assembly 21, and the other end of the input shaft 22 has a second guide; the first end of the output shaft 12 is arranged opposite to the other end of the input shaft 22, and is connected and installed via the first guide and the second guide, so that the output shaft 12 drives the rotating input shaft 22, and the input shaft 12 drives the transducer assembly 21 to move linearly.

[0034] In this embodiment, the drive assembly 11 is used to drive the output shaft 12 to rotate. It can be a drive device such as a stepper motor or a servo motor, or it can be other devices that can drive the output shaft 12 to rotate, and no further limitation is given here. The input shaft 22 and the output shaft 12 are both made of metal materials, such as stainless steel, titanium alloy, etc., which are strong and wear-resistant. The transducer assembly 21 includes a transducer motion assembly 19 and a transducer body 212. The transducer motion assembly 19 is connected to the input shaft 22 and can convert the rotational motion of the input shaft 22 into linear reciprocating motion, and drive the transducer body 212 to perform linear reciprocating motion, thereby achieving the planar treatment effect of the treatment handle 10. A first guide member is formed at the other end of the output shaft 12, and a second guide member is formed at the other end of the input shaft 22. When the handle body 1 and the treatment head 2 are assembled, the first guide member on the output shaft 12 abuts against the second guide member of the input shaft 22, and then the first guide member and the second guide member slide relative to each other to achieve a quick connection between the output shaft 12 and the input shaft 22, and then achieve a quick connection between the handle body 1 and the treatment head 2, thereby improving work efficiency.

[0035] The technical solution of the present application sets a first guide member at the first end of the output shaft 12 and a second guide member at the other end of the input shaft 22. The first end and the other end are arranged opposite to each other. When the other end of the output shaft 12 is connected to the first end of the input shaft 22, the output shaft 12 and the input shaft 22 are quickly connected by connecting and installing between the first guide member and the second guide member. The driving shaft of the driving assembly 11 drives the output shaft 12 to rotate, and then drives the input shaft 22 to rotate, and finally drives the transducer assembly 21 to move, saving installation time and improving work efficiency.

[0036] The connection between the first guide member and the second guide member is any mechanical connection method, including one or more of magnetic connection, threaded connection, sliding connection, bayonet connection, key connection, coupling, welding or any other known connection.

[0037] Specifically, in one embodiment, the first guide member includes a plurality of bosses 121 protruding from the first end of the output shaft 12, and the plurality of bosses 121 are arranged at intervals along the circumferential direction of the output shaft 12, and each boss 121 extends along the radial direction of the output shaft 12. Two guide surfaces 122 are formed at one end of the boss 121 close to the treatment head 2, and two first transmission inclined surfaces 123 are formed at one end of the boss 121 away from the treatment head 2; the second guide member includes a plurality of protrusions 221 provided at the other end of the input shaft 12, and the plurality of protrusions 221 are distributed at intervals along the circumferential direction of the input shaft 22, and an accommodating groove 222 is formed between two adjacent protrusions 221 for accommodating the boss 121; two guide ribs 223 are formed on both sides of each protrusion 221, and two second transmission inclined surfaces 224 are formed at an angle between the two guide ribs 223.

[0038] In this embodiment, a plurality of bosses 121 are provided on the other end of the output shaft 12, one end of each boss 121 converges at the middle position of the output shaft 12, and the other end of each boss 121 is evenly distributed in the circumferential direction of the output shaft 12. The angle between each two bosses 121 should be the same, and the plurality of bosses 121 are symmetrically distributed around the center of the output shaft 12. The number of bosses 121 should be more than three, and can be three, four or five, etc., and is not further limited here. Correspondingly, a plurality of protrusions 221 are provided on the other end of the input shaft 22, and the plurality of protrusions 221 are evenly distributed along the circumferential direction of the input shaft 22. The angles between each two protrusions 221 should be the same, and the plurality of protrusions 221 are symmetrically distributed with the center of the input shaft 22 as the center. The number of protrusions 221 should be consistent with the number of bosses 121, which can be three, four or five, etc. The plurality of protrusions 221 enclose a receiving groove 222, and the shape of the receiving groove 222 is the same as the shape formed by the combination of the plurality of bosses 121. The plurality of bosses 121 are arranged in the receiving groove 222 so that the output shaft 12 can drive the input shaft 22 to rotate together. Two guide surfaces 122 set at an angle are formed on both sides of the top surface of each boss 121. Correspondingly, two guide ribs 223 set at an angle are formed on both sides of the top surface of each protrusion 221. The angle between the two guide ribs 223 with a close distance between two adjacent protrusions 221 should be the same as the angle between the two guide surfaces 122 on the same boss 121, so that each boss 121 can be inserted between two adjacent protrusions 221, and then the output shaft 12 drives the input shaft 22 to rotate together. The mutually cooperating structure of the boss 121 and the protrusion 221 as above can enable the output shaft 12 and the input shaft 22 to be assembled into one in any state without manually adjusting the position of the output shaft 12 or the input shaft 22, thereby saving time and improving efficiency. Two first transmission bevels 123 are also formed at the end of the boss 121 away from the treatment head 2. Correspondingly, two second transmission bevels 224 are formed at an angle between the two guide ridges 223. When the output shaft 12 and the input shaft 22 are installed, a first transmission bevel 123 abuts against a second transmission bevel 224, and the first transmission bevel 123 pushes the second transmission bevel 224 so that the output shaft 12 can drive the input shaft 22 to rotate together. The provision of the first transmission bevel 123 and the second transmission bevel 224 can make the connection between the input shaft 22 and the output shaft 12 more stable and the transmission effect better.

[0039] In one embodiment, a first chamfer 124 is provided between two first transmission slopes 123 between two adjacent bosses 121 ; a second chamfer 225 is provided between two second transmission slopes 224 on the same protrusion 221 ; and the first chamfer 124 and the second chamfer 225 are interference fit.

[0040] In order to further improve the transmission effect between the input shaft 22 and the output shaft 12, in this embodiment, a first chamfer 124 is provided between the two first transmission inclined surfaces 123 between two adjacent bosses 121. Correspondingly, a second chamfer 225 is provided between the two second transmission inclined surfaces 224 on the same boss 221. When the output shaft 12 and the input shaft 22 are assembled and connected, the second chamfer 225 is interference fit with the first chamfer 124, making the connection between the input shaft 22 and the output shaft 12 tighter.

[0041] In one embodiment, the included angle between the two guide surfaces 122 on the same boss 121 is 10°-120°.

[0042] In this embodiment, the angle between the two guide surfaces 122 on the same boss 121 is 10°-120°, for example, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, or 120°. Of course, any angle within this range is also possible, and this application does not impose any further restrictions. A larger angle makes assembly of the treatment head 2 more difficult, but the connection is more stable. A smaller angle makes assembly of the treatment head 2 easier, but the connection is less stable.

[0043] In one embodiment, the guide surface 122 includes a guide slope or a guide curved surface.

[0044] In this embodiment, the guide surface 122 can be either a guide slope or a flat surface, capable of pushing against the guide ribs 223 to rotate the input shaft 22. It is understood that the guide surface 122 can also be a guide curved surface. By designing the curvature of the curved surface and the angle of the guide ribs 223, the curved surface can also push against the guide ribs 223, thereby driving the input shaft 22 to rotate.

[0045] In one embodiment, a first safety plane 125 is provided at the intersection of the two guide surfaces 122 on the same boss 121 , and the width of the first safety plane 125 is 0.01-2 mm.

[0046] In this embodiment, in order to prevent the angle at the intersection of the two guide surfaces 122 from being too sharp and causing injury to the operator, a first safety plane 125 is provided at the intersection of the two guide surfaces 122 to soften the sharp angle and prevent injury. The width of the first safety plane 125 is 0.01-2 mm, for example, 0.01 mm, 0.08 mm, 0.4 mm, 1 mm, 1.5 mm, 2 mm, etc. Of course, it can also be any value within the above range, and this application does not impose any further restrictions on this.

[0047] In one embodiment, each protrusion 221 is further formed with two cutting bevels 226 at an angle, a guide ridge 223 is provided at the connection between a cutting bevel 226 and a second transmission bevel 224, and a second safety plane 227 is provided at the connection between the two cutting bevels 226, and the width of the second safety plane 227 is 0.01-2 mm.

[0048] In this embodiment, two cutting bevels 226 are formed at an angle on the protrusion 221. The guide rib 223 is provided at the junction of one cutting bevel 226 and a second transmission bevel 224, which facilitates machining to form the guide rib 223 on the protrusion 221. A second safety plane 227 is provided at the junction of the two cutting bevels 226 to soften the sharp angle and prevent injuries to the operator. The width of the second safety plane 227 is 0.01-2 mm, for example, 0.01 mm, 0.08 mm, 0.4 mm, 1 mm, 1.5 mm, 2 mm, etc., and of course any value within the above range may also be used, and this application does not impose any further restrictions on this.

[0049] The present application also provides an installation method, which is applied to install the treatment handle 10 as described above, comprising the following steps:

[0050] Step S1: controlling the guide surface 122 to abut against the guide ridge 223;

[0051] Step S2: controlling the guide surface 122 to move along the guide ridge 223 .

[0052] In this embodiment, the guide surface 122 is first controlled to abut against the guide ridge 223 to perform a preliminary guiding effect to preliminarily connect the output shaft 12 and the input shaft 22, and then the guide surface 122 is controlled to move along the guide ridge 223, thereby realizing the movement of the output shaft 12 relative to the input shaft 22, realizing a quick connection between the output shaft 12 and the input shaft 22, and improving work efficiency.

[0053] In one embodiment, the guide surface 122 includes a plurality of bosses protruding from the first end, the plurality of bosses being spaced apart along the circumference of the output shaft 12, and each boss extending in the radial direction of the output shaft 12; two guide surfaces are formed on one end of the boss proximal to the treatment head 2; the guide ribs 223 include a plurality of protrusions provided at the other end of the input shaft 12, the plurality of protrusions being spaced apart along the circumference of the input shaft 12, and a receiving groove being formed between two adjacent protrusions for receiving the bosses; two guide ribs 223 are formed on each side of each protrusion; and the installation method includes the following steps:

[0054] Control the guide surface to abut against the guide ridge 223;

[0055] The guide surface is controlled to move along the guide ridge 223 .

[0056] In one embodiment, the treatment handle 10 further includes an output shaft 12 control assembly, and before the step of controlling the guide surface 122 to abut against the guide ridge 223, the step further includes:

[0057] Step S1 ′: controlling the output shaft 12 control component to lock the output shaft 12 .

[0058] In this embodiment, the end of the treatment handle 10 is further provided with an output shaft 12 control assembly. Before the control guide surface 122 abuts the guide rib 223, the output shaft 12 control assembly locks the output shaft 12, preventing it from rotating. This prevents the output shaft 12 from being pushed by the input shaft 22 and misaligned, which could lead to connection failure. The output shaft 12 control assembly can be a combination of a sleeve and a photoelectric sensor. One end of the sleeve is mounted on the drive shaft of the drive assembly 11, and the other end is connected to the output shaft 12. A baffle is provided on the outer wall of the sleeve. The baffle has two states: blocking the optical path of the photoelectric sensor and avoiding the optical path of the photoelectric sensor. The output shaft 12 is pre-set to be in the calibration state when it blocks the optical path of the photoelectric sensor. Once the photoelectric sensor detects no optical signal, indicating that the output shaft 12 is in the initial state, the photoelectric sensor controls the drive assembly 11 to lock the drive shaft, thereby locking the output shaft 12 and directly assembling and connecting the output shaft 12 to the input shaft 22. It should be noted that the output shaft 12 control component can also be other devices, such as an angle sensor, which detects the angle change of the output shaft 12 to determine and control whether it is in the initial state.

[0059] In one embodiment, the transducer assembly 21 includes a transducer motion assembly 19 and a transducer body 212. The transducer motion assembly 19 is connected to one end of the input shaft 22 and is used to convert the rotational motion of the input shaft 22 into linear reciprocating motion of the transducer body 212. The transducer body 212 has an initial installation position. After the step of controlling the guide surface 122 to move along the guide ridge 223, the method further includes:

[0060] Step S3: controlling the transducer body 212 to restore the initial installation position.

[0061] In this embodiment, the transducer assembly 21 includes a transducer motion assembly 19 and a transducer body 212. The rotary motion portion 211 is connected to the input shaft 22 and can convert the circumferential rotation of the input shaft 22 into linear reciprocating motion, thereby driving the transducer body 212 to perform linear reciprocating motion. The transducer motion assembly 19 can be a crank slider mechanism or a combination of a toothless gear and a rack, which is not further limited in this application. When the locked output shaft 12 is connected to the input shaft 22, the first guide bevel can push against the second guide bevel, thereby driving the input shaft 22 to rotate, causing the input shaft 22 to also rotate to a correction state, thereby driving the transducer motion assembly 19 and the transducer body 212 to move together until the transducer body 212 returns to directly below the input shaft 22 and returns to its initial position, facilitating the next treatment.

[0062] The present application also proposes a treatment handle 10, which, in conjunction with Figures 7 to 9, includes a handle body 24 and a treatment head (not shown). The handle body 24 includes a drive assembly 11 and a sensor assembly 6. The sensor assembly 6 is electrically connected to the drive assembly 11 to detect and control the rotation angle of the drive shaft 20 of the drive assembly 11. The drive shaft 20 has a preset correction position; the treatment head includes an input shaft and a transducer assembly 21, one end of the input shaft is connected to the drive shaft 20, and the other end of the input shaft is connected to the transducer assembly 21; the drive shaft 20 drives the rotating input shaft; and the transducer assembly 21 is driven by the input shaft to move linearly.

[0063] In this embodiment, a sensor assembly 6 is provided on the handle body 24 of the treatment handle 10 to detect the position of the drive shaft 20 of the drive assembly 11. The sensor assembly 6 is electrically connected to the drive assembly 11, automatically controlling the rotation of the drive shaft 20 of the drive assembly 11 to a specified position and promptly stopping and locking the drive shaft 20, thereby aligning and connecting the drive shaft 20 with the input shaft of the treatment head. This eliminates the need for repeated manual calibration, saving manpower and time. The sensor assembly 6 can be a Hall effect sensor disposed on the outer wall of the drive shaft 20, which determines whether the position of the drive shaft 20 is corrected by measuring the rotation angle of the drive shaft 20. Alternatively, a photoelectric sensor can be provided, wherein a notched convex plate is disposed on the outer wall of the drive shaft 20 to block the light signal received by the photoelectric sensor. The corrected position of the drive shaft 20 is set so that when the photoelectric sensor receives the light signal, the drive shaft 20 is in the corrected position, thereby achieving automatic correction of the drive shaft 20. This is not further defined in this application. The drive assembly 11 is a common commercially available motor assembly. The model and specifications should be selected based on the specifications and speed requirements of the treatment handle 10, and this is not further defined in this application.

[0064] The technical solution of the present application adopts a sensor component 6 to detect the rotation angle state of the driving shaft 20 of the driving component 11, and is electrically connected to the driving component 11, so as to control the rotation or timely stop of the driving shaft 20 of the driving component 11, thereby realizing automatic correction of the driving shaft 20 of the handle body 24, and being able to lock the driving shaft 20 after the driving shaft 20 rotates to the correction position, thereby realizing rapid installation of the handle body 24 and the treatment head, saving manpower and time costs.

[0065] In one embodiment, the handle body 24 further includes a first limiting portion 5 , which is used to limit the rotation angle of the driving shaft 20 .

[0066] In this embodiment, a first limit portion 5 is provided on the handle body for limiting the rotation angle of the drive shaft 20. When the drive shaft 20 abuts the first limit portion 5 and cannot continue to rotate, the rotation position of the drive shaft 20 at this time is set as the correction position. Subsequently, it is only necessary to control the drive shaft 20 of the drive assembly 11 to rotate to abut the first limit portion 5 through the sensor assembly 6. This can save the step of detecting the current rotation angle of the drive shaft 20, further improve the speed of correcting the drive shaft 20, and then quickly connect the handle body 24 and the treatment head, saving manpower and time costs.

[0067] In one embodiment, the transducer assembly 21 includes a transducer motion assembly 21 and a transducer body 212. The transducer motion assembly 21 is connected to the other end of the input shaft on one side and to the transducer body on the other side to convert the rotational motion of the input shaft into linear reciprocating motion of the transducer body.

[0068] In this embodiment, the transducer assembly 21 includes a transducer motion assembly 21 and a transducer body 212. The transducer motion assembly 21 is connected to the other end of the input shaft and can convert the circumferential rotation of the input shaft into linear reciprocating motion, thereby driving the transducer body 212 to perform linear reciprocating motion, thereby achieving a planar therapeutic effect. The transducer motion assembly 21 can be a crank slider mechanism or a combination of a toothless gear and a rack, which is not further limited in this application.

[0069] In one embodiment, the transducer body 212 has a preset position, and when the driving shaft 20 in the calibration position is connected to the input shaft, the transducer body 212 returns to the preset position.

[0070] In this embodiment, to facilitate subsequent treatment, the transducer body 212 is configured with a preset position. The preset position can be the center of the treatment head, a side of the treatment head, or any other position, without further limitation. When the drive shaft 20, in the calibrated position, is connected to the input shaft, the drive shaft 20 is locked, driving the input shaft to rotate, which in turn drives the transducer motion assembly 21, and thus the transducer body 212, returning it to the preset position.

[0071] In one embodiment, the treatment head further includes a second limiting portion (not shown), which is used to limit the displacement distance of the transducer body 212 .

[0072] In this embodiment, a second limiting portion is provided on the treatment head, and the second limiting portion is used to limit the displacement distance of the transducer body 212 to prevent the transducer body 212 from being displaced too much and causing a stuck phenomenon.

[0073] As shown in Figures 7 to 9, in one embodiment, the handle body 24 also includes a sleeve 3, one end of which is sleeved on the drive shaft 20, and the outer peripheral wall of the sleeve 3 is provided with a shielding portion 31; the sensor component 6 is a photoelectric sensor component 332, and the photoelectric sensor component 332 is arranged close to the sleeve 3, and the shielding portion 31 has a first state of blocking the optical signal of the photoelectric sensor component 332 and a second state of avoiding the optical signal of the photoelectric sensor component 332.

[0074] In this embodiment, a photoelectric sensor assembly 332 is used as the sensor assembly 6 for detecting the position of the drive shaft 20. A sleeve 3 is provided around the outer periphery of the drive shaft 20, capable of rotating with the drive shaft 20. A shielding portion 31 is provided on the outer periphery of the sleeve 3. When the shielding portion 31 is in a first state, it blocks the reception of a light signal from the photoelectric sensor; when the shielding portion 31 is in a second state, it blocks the reception of the light signal from the photoelectric sensor. The position of the sleeve 3 is preset. When the shielding portion 31 is in the first state, the position of the drive shaft 20 at that time is defined as the calibration position. When the position of the drive shaft 20 needs to be calibrated, the photoelectric sensor determines whether it receives a light signal. If a light signal is received, it indicates that the shielding portion 31 is in the second state and the position of the drive shaft 20 is not the calibration position. The drive assembly 11 is controlled to rotate the drive shaft 20 until the photoelectric sensor no longer receives a light signal. If no light signal is received, it indicates that the shielding portion 31 is in the first state and the position of the drive shaft 20 is in the calibration position, requiring no calibration. The material of the sleeve 3 can be metal, such as stainless steel or titanium alloy, or engineering plastic, and is not further limited herein. It is understood that, provided that the light signal can be blocked, the shorter the length of the shielding portion 31, the more accurate the position correction of the drive shaft 20. The specific length should be selected based on actual needs and is not further limited in this application.

[0075] In one embodiment, referring to FIG. 9 , there are two shielding portions 31 , which are symmetrically disposed on the outer peripheral wall of the shaft sleeve 3 .

[0076] In this embodiment, since the drive shaft 20 is generally cylindrical and has a centrally symmetrical structure at its end, the correcting position of the drive shaft 20 is not unique. Therefore, two shielding portions 31 are symmetrically provided on the outer peripheral wall of the sleeve 3 to shorten the time required to correct the drive shaft 20, further saving time and improving efficiency.

[0077] Please refer to Figures 7 and 8. In one embodiment, the handle body 24 also includes a shell (not shown) and a bracket 4. The shell has a accommodating cavity and is provided with an avoidance hole for the drive shaft 20 to pass through. The bracket 4 is installed in the accommodating cavity, and the drive assembly 11 is provided in the accommodating cavity and installed on the bracket 4.

[0078] In this embodiment, the handle body 24 further includes a housing and a bracket 4. The housing has a housing cavity and a clearance hole. The bracket 4, drive assembly 11, and sensor assembly 6 are all disposed within the housing cavity, protected by the housing and providing waterproof and dustproof protection. The bracket 4 is connected to the housing on one side and to the drive assembly 11 on the other, providing stable support for the drive assembly 11. The drive shaft 20 passes through the clearance hole in the housing and connects to the input shaft of the treatment head, enabling power output from the drive assembly 11 to the treatment head. Both the housing and bracket 4 can be made of metal, such as aluminum alloy or titanium alloy, or can be made of hard engineering plastic, without further limitation.

[0079] In one embodiment, with reference to Figures 7 and 8, the bracket 4 includes a base 41 for fixing the driving assembly 11 and a baffle 42 connected to the base 41, and the baffle 42 is arranged parallel to the axial direction of the sleeve 3; the photoelectric sensor assembly 332 includes two opposing support arms 213, a transmitting portion 2111 and a receiving portion 2121, the two support arms 213 are spaced apart from each other on the baffle 42, the transmitting portion 2111 and the receiving portion 2121 are respectively arranged opposite to the two support arms 213, and when the shielding portion 31 is in the first state, it is located between the transmitting portion 2111 and the receiving portion 2121.

[0080] In this embodiment, the bracket 4 includes a base 41 and a baffle 42. The base 41 is used to install and fix the drive assembly 11. The baffle 42 is arranged parallel to the axial direction of the sleeve 3 and is used to install the photoelectric sensor assembly 332. The photoelectric sensor assembly 332 includes a beam support arm 213, a transmitting part 2111 and a receiving part 2121. The two support arms 213 are spaced apart and arranged on the baffle 42 toward the direction of the sleeve 3. The transmitting part 2111 and the receiving part 2121 are also respectively arranged at the relative positions of the two support arms 213 to realize the emission and reception of light signals. When the shielding part 31 is in the first state, it can be located between the transmitting part 2111 and the receiving part 2121 to block the reception of light signals, thereby helping to judge the position state of the drive shaft 20 and correct the drive shaft 20.

[0081] The present application also proposes an ultrasonic therapeutic device (not shown), which includes a therapeutic handle 10. The specific structure of the therapeutic handle 10 refers to the above-mentioned embodiment. Since the ultrasonic therapeutic device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0082] In one embodiment of the present application, a treatment head 2 is proposed, which, with reference to Figures 10 and 11, includes an input shaft 22, a transducer motion assembly 19 and a transducer 18 (the same as the transducer body 212 in the aforementioned embodiment). One end of the input shaft 22 is connected to the output shaft 12 of the drive assembly 11; the transducer motion assembly 19 includes a rotational motion part 211 and a linear motion part 1222, the rotational motion part 211 is drivingly connected to the other end of the input shaft 22 away from the output shaft 12, and the linear motion part 1222 is drivingly connected to the rotational motion part 211; the transducer 18 is connected to the linear motion part 1222, and the input shaft 22 drives the rotational motion part 211 to rotate; the linear motion part 1222 is driven by the rotational motion part 211 to move linearly, so that the transducer 18 moves linearly.

[0083] In this embodiment, the input shaft 22 is used to transmit the driving force from the output shaft 12 of the drive assembly 11. One end is connected to the output shaft 12. The connection between the input shaft 22 and the output shaft 12 can be a direct connection because the rotation speed is relatively low. It can also be connected by other connection methods such as a coupling or a key connection. This application does not impose any further restrictions on this. As long as the input shaft 22 can rotate with the output shaft 12, it can be sufficient. The transducer motion assembly 19 includes a rotational motion portion 211 and a linear motion portion 1222. The rotational motion portion 211 is connected to the other end of the input shaft 22. The rotational motion portion 211 and the input shaft 22 can be connected by screw connection, clamping, or welding, etc. As long as the rotational motion portion 211 can rotate with the input shaft 22, this application does not impose any further restrictions on this.

[0084] The rotary motion portion 211 drives and connects to the linear motion portion 1222, converting the rotary motion of the rotary motion portion 211 into linear motion of the linear motion portion 1222, thereby driving the transducer 18 connected to the linear motion portion 1222 to perform linear reciprocating motion. It should be noted that the combination of the rotary motion portion 211 and the linear motion portion 1222 can be a crank-slider structure, where the crank is connected to the slider, and a groove is provided to limit the movement trajectory of the slider to a straight line. The input shaft 22 drives the crank to rotate together, thereby driving the slider to perform linear reciprocating motion along the groove, thereby driving the transducer 18 to perform linear reciprocating motion.

[0085] In one embodiment, the combination of the rotational motion part 211 and the linear motion part 1222 can also be a combination of a toothless gear and a rack. The two racks are symmetrically arranged on both sides of the toothless gear, and the two racks can move together. The toothless gear rotates unidirectionally under the drive of the input shaft 22. When the tooth portion of the toothless gear engages with the tooth portion of one of the racks, the rack moves in a tangential direction of the rotation direction of the toothless gear. When the tooth portion of the toothless gear rotates to the other side, it engages with the tooth portion of the other rack, driving the rack to move in a tangential direction of the rotation direction of the toothless gear. Since the rotation directions of the toothless gears on both sides are opposite, the linear reciprocating motion of the rack can be realized.

[0086] In one embodiment, the combination of the rotational motion portion 211 and the linear motion portion 1222 can also be a gear and rack combination. In this case, the input shaft 22 should exhibit periodic bidirectional rotational motion, with the gear teeth meshing with the rack teeth. The input shaft 22 drives the gear to perform periodic bidirectional rotational motion, thereby driving the rack and the transducer 18 connected thereto to perform linear reciprocating motion. The combination of the rotational motion portion 211 and the linear motion portion 1222 is not limited to a single combination, as long as it can convert the rotational motion of the input shaft 22 into linear reciprocating motion of the transducer 18. This is not further limited herein.

[0087] The treatment head 2 proposed in the technical solution of this application includes an input shaft 22, a transducer motion assembly 19, and a transducer 18. The transducer motion assembly 19 further includes a rotational motion portion 211 and a linear motion portion 1222. The output shaft 12 of the drive assembly 11 is connected to the input shaft 22, transmitting the power of the drive assembly 11 to the input shaft 22 of the treatment head 2. The input shaft 22 then drives the rotational motion portion 211 to rotate, and finally drives the linear motion portion 1222, converting the rotational motion of the input shaft 22 into linear reciprocating motion of the linear motion portion 1222. The transducer 18 is connected to the linear motion portion 1222 to follow the linear motion portion 1222 in linear reciprocating motion, thereby achieving planar treatment of the treatment head 2 and saving manpower. The treatment head 2 proposed in this application achieves lateral movement of the transducer 18 through the combination of the rotational motion portion 211 and the linear motion portion 1222, resulting in a simple and compact structure and high transmission efficiency.

[0088] Please refer to Figure 11. In one embodiment, the input shaft 22 drives the rotary motion part 211 to perform bidirectional reciprocating rotation. The rotary motion part 211 is provided with a plurality of first teeth 1211 on a side facing the linear motion part 1222, and the linear motion part 1222 is provided with a plurality of second teeth 1221 on a side facing the rotary motion part 211. The plurality of first teeth 1211 are meshed and connected with the plurality of second teeth 1221 to drive the linear motion part 1222 to perform linear reciprocating motion.

[0089] In this embodiment, the output shaft 12 of the driving component 11 has a periodic bidirectional rotation state. A plurality of first teeth 1211 are provided on one side of the rotational motion part 211, and a plurality of second teeth 1221 meshing with the first teeth 1211 are provided on the side of the linear motion part 1222 facing the rotational motion part 211. Through the meshing of the first teeth 1211 and the second teeth 1221, the rotational motion part 211 drives the linear motion part 1222 to move along the rotation tangent direction of the rotational motion part 211. Since the rotational motion part 211 performs periodic bidirectional rotation together with the input shaft 22, the linear motion part 1222 and the transducer 18 connected to the linear motion part 1222 perform horizontal linear reciprocating motion under the drive of the rotational motion part 211, thereby realizing the plane scanning treatment of the treatment head 2. The transmission method of tooth meshing has high transmission efficiency. The specific lengths of the first tooth portion 1211 and the second tooth portion 1221, as well as specific parameters of the teeth, such as the number of teeth or the module of the teeth, should be selected based on specific needs and are not further specified in this application. The linear motion portion 1222 and the rotary motion portion 211 can be made of lightweight, self-lubricating engineering plastics, or metals, such as stainless steel or aluminum alloy, which are durable and wear-resistant. This application does not further specify these materials.

[0090] Please refer to Figure 11 again. In one embodiment, a limiting groove 1212 extending along the circumferential direction is defined on the other side of the rotational motion portion 211 away from the first tooth portion 1211. The treatment head 2 also includes a limiting portion 14. One end of the limiting portion 14 is provided on the transducer 18, and the other end is exposed in the limiting groove 1212 to limit the rotation angle of the rotational motion portion 211.

[0091] In this embodiment, a limiting groove 1212 is provided on the other side of the rotary motion part 211 away from the first tooth portion 1211. The limiting groove 1212 extends along the circumferential direction of the rotary motion part 211. A limiting portion 14 is also provided. The limiting portion 14 is provided in the limiting groove 1212 to limit the rotation angle of the rotary motion part 211. This prevents the linear motion part 1222 from moving too long due to the rotation angle of the rotary motion part 211 being too large, thereby colliding with the housing or other components and damaging the device. The specific length of the limiting groove 1212 and the installation position of the limiting portion 14 should be determined according to actual needs and are not further limited in this application. It is understandable that in other embodiments, the rotation angle and rotation period of the rotary motion part 211 can also be controlled by adjusting and controlling the speed and rotation period of the drive assembly 11, thereby controlling the movement distance and reciprocating frequency of the linear motion part 1222.

[0092] In one embodiment, as shown in FIG. 11 , there are two linear motion parts 1222 , which are symmetrically disposed on both sides of the rotary motion part 211 , and both sides of the transducer 18 are connected to the two linear motion parts 1222 , respectively.

[0093] In this embodiment, two linear motion portions 1222 are symmetrically disposed on either side of the rotational motion portion 211. The two sides of the transducer 18 are respectively connected to the two linear motion portions 1222. This provides a more stable connection between the transducer 18 and the linear motion portions 1222, and a smoother movement of the transducer 18. It will be appreciated that in other embodiments, due to the provision of the limiting portion 14 and the limiting groove 1212, the rotational motion portion 211 only engages with the linear motion portion 1222 on one side. Therefore, a non-toothed connecting strip may be provided on the other side of the rotational motion portion 211, which can also achieve a more stable connection and smoother movement of the transducer 18.

[0094] In one embodiment, with reference to FIG11 , the output shaft 12 can drive the rotary motion portion 211 to rotate in one direction. A side portion of the rotary motion portion 211 facing the linear motion portion 1222 is provided with a plurality of third teeth (not shown). There are two linear motion portions 1222 symmetrically arranged on both sides of the rotary motion portion 211. A plurality of fourth teeth (not shown) are provided on a side of the two linear motion portions 1222 facing the rotary motion portion 211. The plurality of third teeth are meshed with the plurality of fourth teeth to drive the two linear motion portions 1222 to perform linear reciprocating motion.

[0095] In this embodiment, the output shaft 12 of the driving assembly 11 rotates unidirectionally, driving the input shaft 22 of the treatment head 2 to rotate unidirectionally, and then driving the rotary motion part 211 to rotate unidirectionally. The two linear motion parts 1222 are symmetrically arranged on both sides of the rotary motion part 211. The rotary motion part 211 rotates unidirectionally, and several third teeth of the rotary motion part 211 are first engaged and connected with the fourth teeth of the linear motion part 1222 on one side, driving the two linear motion parts 1222 to perform linear motion along the tangential direction of the rotation of the rotary motion part 211. When the rotary motion part 211 rotates to the other side and engages with the fourth teeth of the other linear motion part 1222, it drives the two linear motion parts 1222 to perform linear motion along the tangential direction of the rotation of the rotary motion part 211 in the opposite direction to the previous direction. The above process is then repeated to make the transducer 18 perform reciprocating linear motion, thereby achieving the planar treatment effect of the treatment head 2. The transmission method of tooth engagement has high transmission efficiency. The specific lengths of the third and fourth tooth portions and the specific parameters of the tooth portions, such as the number of teeth or the module of the teeth, should be selected based on specific needs and are not further limited in this application. The linear motion portion 1222 and the rotary motion portion 211 of this embodiment can be made of engineering plastics, which are lightweight and have certain self-lubricating properties, or metal materials, such as stainless steel or aluminum alloy, which are strong and wear-resistant. This application does not further limit this.

[0096] Please refer to Figure 10. In one embodiment, the treatment head 2 also includes a transducer bracket 17. The transducer bracket 17 includes a fixing portion 171 and a clamping portion 172. The fixing portion 171 is used to connect with the linear motion portion 1222. The clamping portion 172 is connected to the other side of the fixing portion 171 facing away from the linear motion portion 1222. The clamping portion 172 is used to clamp the transducer 18.

[0097] In this embodiment, a transducer bracket 17 is provided for connecting the linear motion portion 1222 and the transducer 18, thereby stably connecting the transducer 18. The transducer bracket 17 includes a fixing portion 171 and a clamping portion 172. The fixing portion 171 is connected to the linear motion portion 1222, and the clamping portion 172 is connected to the side of the fixing portion 171 facing away from the linear motion portion 1222. The connection method can be screw connection or welding, which is not further limited here. The clamping portion 172 is used to clamp the transducer 18, which facilitates the removal and replacement of the transducer 18 compared to other connection methods.

[0098] In one embodiment, with reference to FIG10 , the treatment head 2 further includes a mounting base 15 , a relief hole 151 is defined in the middle of the mounting base 15 , the input shaft 22 passes through the relief hole 151 and is connected to the output shaft 12 , and a seal 152 is provided between the input shaft 22 and the mounting base 15 .

[0099] In this embodiment, the treatment head 2 is provided with a mounting base 15. The mounting base 15 has an avoidance hole 151 for the input shaft to pass through, so that it is driven by the output shaft 12 to rotate. The input shaft 22 then drives the rotational motion portion 211 and the linear motion portion 1222, converting the rotational motion of the output shaft 12 into lateral reciprocating motion of the transducer 18, thereby achieving planar treatment of the treatment head 2. Because the transducer 18 requires the assistance of an acoustic medium to transmit ultrasonic waves during operation, a seal 152 is required between the input shaft 22 and the mounting base 15 to seal the treatment head 2 and prevent leakage of the acoustic medium, which would affect the operating effect of the transducer 18. The seal 152 can be a sealing ring or a sealing strip, or even a sealing method such as glue, which is not required by this application. The mounting base 15 can be made of hard plastic or metal, such as aluminum alloy, without further limitation.

[0100] In one embodiment, with reference to Figures 10 and 11, the treatment head 2 further includes a guide rail 16, which is provided on a surface of the mounting base 15 away from the output shaft 12, and the linear motion portion 1222 is slidably connected to the guide rail 16 on the other side away from the rotational motion portion 211 to perform linear motion along the extension direction of the guide rail 16.

[0101] In order to control the motion trajectory of the linear motion portion 1222, and thereby the motion trajectory of the transducer 18, in this embodiment, a guide rail 16 is provided on the surface of the mounting base 15 facing away from the drive shaft. The guide rail 16 is slidably connected to the side of the linear motion portion 1222 facing away from the rotary motion portion 211, so that the linear motion portion 1222 can only perform linear reciprocating motion along the guide rail 16. It should be noted that a ridge may be provided on the guide rail 16, and a groove may be provided on the side of the linear motion portion 1222 facing away from the rotary motion portion 211. The ridge slides within the groove, allowing the linear motion portion 1222 to perform linear motion along the guide rail 16. Alternatively, a groove may be provided on the guide rail 16, and a ridge may be provided on the side of the linear motion portion 1222 facing away from the rotary motion portion 211. The ridge slides within the groove, allowing the linear motion portion 1222 to perform linear motion along the guide rail 16. This is not further limited in this application.

[0102] This application also provides a treatment handle (not shown) comprising a handle body 1 and a treatment head 2. The specific structure of the treatment head 2 is similar to that of the aforementioned embodiments. Since this treatment handle utilizes all the technical solutions of all of the aforementioned embodiments, it possesses at least all the beneficial effects of the technical solutions of the aforementioned embodiments, and therefore will not be further detailed here. The handle body 1 includes a drive assembly 11, and the treatment head 2 is the treatment head 2 described in any of the aforementioned embodiments. The output shaft 12 of the drive assembly 11 drives an input shaft 22 connected to the treatment head 2.

[0103] In this embodiment, the treatment handle includes a handle body 1 and a treatment head 2. A drive assembly 11 is disposed within the handle body 1. The drive assembly 11 has a rotating output shaft 22, such as a motor. A first guide member is provided at a first end of the output shaft 22, and a second guide member is provided at the other end of the input shaft 22 of the treatment head 2, thereby achieving a driving connection between the output shaft 12 of the drive assembly 11 and the rotation of the input shaft 22 of the treatment head 2. This transmits the driving force of the drive assembly 11 to the input shaft 22 of the treatment head 2, thereby driving the transducer motion assembly 19 and the transducer 18 to perform linear motion. The connection and installation of the first guide member of the output shaft 12 and the first and second guide members of the second guide member of the input shaft 22 may be achieved by any mechanical connection method, including one or more of a magnetic connection, a threaded connection, a sliding connection, a bayonet connection, a key connection, a coupling, welding, or any other known connection. Direct connection may also be employed, and this is not further limited herein.
