[0012] Regarding the realization of the objectives, functional features and advantages of this application, further explanations will be given in conjunction with the embodiments with reference to the accompanying drawings.

[0013] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments.

[0014] In addition, the descriptions related to "first", "second", etc. in the present application are only for the purpose of description and should not be understood as indicating or implying their relative importance or implicitly indicating the number of technical features. Thus, the features limited by "first" and "second" may explicitly or implicitly include at least one such feature. Furthermore, the technical solutions between the embodiments may be combined with each other, but they must be based on what can be realized by those skilled in the art. If the combination of technical solutions conflicts with each other or cannot be realized, such a combination of technical solutions does not exist and is not included within the protection scope required by the present application.

[0015] The treatment handle of a conventional ultrasonic therapeutic apparatus usually includes a treatment head and a handle, and it is necessary to manually align and connect the input axis of the treatment head and the output axis of the handle, which is time-consuming and affects efficiency. Therefore, the present application provides a treatment handle that can quickly attach a handle body and a treatment head.

[0016] This application proposes a treatment handle 10, which is a handle body 1 including a drive assembly 11. The drive assembly has an output shaft 12 that rotates. The handle body 1 has a first guide member at a first end of the output shaft 12, and a treatment head 2 including 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 treatment head 2 has a second guide member at the other end of the input shaft 22. The first end of the output shaft 12 is disposed opposite to the other end of the input shaft 22. By connecting and attaching the first guide member and the second guide member, the output shaft 12 drives the rotating input shaft 22, and the transducer assembly 21 is linearly moved by the input shaft 12.

[0017] In this embodiment, the drive assembly 11 is used to drive the output shaft 12 to rotate. It may be a driving device such as a stepping motor or a servo motor, or other devices that can drive the output shaft 12 to rotate. Here, it is not limited further. Both the input shaft 22 and the output shaft 12 adopt a metal material such as stainless steel or titanium alloy, which is 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, converts the rotational motion of the input shaft 22 into a linear reciprocating motion to drive the transducer body 212 to perform a linear reciprocating motion, and realizes 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 of the output shaft 12 abuts against the second guide member of the input shaft 22, and then the relative sliding and cooperation between the first guide member and the second guide member can realize a rapid connection between the output shaft 12 and the input shaft 22, and thus realize a rapid connection between the handle body 1 and the treatment head 2, improving the working efficiency.

[0018] In the technical solution of the present application, a first guide member is provided at the first end of the output shaft 12, a second guide member is provided at the other end of the input shaft 22, the first end and the other end are arranged opposite to each other, and when the other end of the output shaft 12 is connected to the first end of the input shaft 22, the connection and attachment between the first guide member and the second guide member realize the rapid connection between the output shaft 12 and the input shaft 22. After the drive shaft of the drive assembly 11 drives the output shaft 12 to rotate, it drives the input shaft 22 to rotate, and finally drives the transducer assembly 21 to move, saving the installation time and improving the working efficiency.

[0019] The connection and attachment between the first guide member and the second guide member are any mechanical connection method, specifically including one or more of magnetic connection, screw connection, slide connection, bayonet connection, key connection, coupling, welding, or any other known connection. Specifically, in one embodiment, the first guide member includes a plurality of bosses 121 protruding from the first end of the output shaft 12. The plurality of bosses 121 are provided 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 the end of the boss 121 close to the treatment head 2, and two first transmission slopes 123 are formed at the end of the boss 121 far 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. The plurality of protrusions 221 are distributed at intervals along the circumferential direction of the input shaft 22, and an accommodation groove 222 for accommodating the boss 121 is formed by surrounding the boss 121 with two adjacent protrusions 221. Two guide ribs 223 are formed on both sides of each boss 221 respectively, and two second transmission slopes 224 forming an angle are formed between the two guide ribs 223.

[0020] In this embodiment, a plurality of bosses 121 are protrudingly provided at the other end of the output shaft 12. One end of each boss 121 converges to an intermediate position of the output shaft 12, and the other ends of each boss 121 are uniformly distributed in the circumferential direction of the output shaft 12. The angle between every two bosses 121 should be the same. The plurality of bosses 121 are symmetrically distributed about the center of the output shaft 12, and the number of bosses 121 should be three or more, and may be three, four, five, etc., and is not limited further herein. Correspondingly, a plurality of protrusions 221 are protrudingly provided at the other end of the input shaft 22. The plurality of protrusions 221 are uniformly distributed along the circumferential direction of the input shaft 22. The angle between every two protrusions 221 should be the same. The plurality of protrusions 221 are symmetrically distributed about the center of the input shaft 22. The number of protrusions 221 must be equal to the number of bosses 121, and may be three, four, five, etc. The plurality of protrusions 221 surround and form an accommodation groove 222. The shape of the accommodation groove 222 is the same as the shape formed by combining the plurality of bosses 121. The plurality of bosses 121 are provided in the accommodation groove 222 so that the output shaft 12 drives the input shaft 22 to rotate together. On both sides of the upper surface of each boss 121, two guide surfaces 122 provided at an angle are formed. Correspondingly, on both sides of the upper surface of each protrusion 221, two guide ribs 223 provided at an angle are formed. The angle between two adjacent guide ribs 223 that are close to each other between two adjacent protrusions 221 should be the same as the angle between the two guide surfaces 122 on the same boss 121. Each boss 121 is inserted between two adjacent protrusions 221, so that the output shaft 12 drives the input shaft 22 to rotate together. With such a structure of the mutual cooperation between the boss 121 and the protrusion 221, the output shaft 12 and the input shaft 22 can be assembled integrally in any state, eliminating the need to manually adjust the positions of the output shaft 12 or the input shaft 22, saving time and improving efficiency.At the end far from the treatment head 2 of the boss 121, two first transmission slopes 123 are further formed. Correspondingly, between the two guide ribs 223, two second transmission slopes 224 forming an angle are formed. After the attachment of the output shaft 12 and the input shaft 22 is completed, one first transmission slope 123 abuts against one second transmission slope 224, and the first transmission slope 123 presses the second transmission slope 224, enabling the output shaft 12 to drive the input shaft 22 to rotate together. By arranging the first transmission slope 123 and the second transmission slope 224, the connection between the input shaft 22 and the output shaft 12 can be made more stable, and the transmission effect is better.

[0021] In one embodiment, a first chamfer 124 is provided between the two first transmission slopes 123 between two adjacent bosses 121, and a second chamfer 225 is provided between the two second transmission slopes 224 on the same protrusion 221. The first chamfer 124 and the second chamfer 225 are in interference fit.

[0022] 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 slopes 123 between two adjacent bosses 121. Correspondingly, a second chamfer 225 is provided between the two second transmission slopes 224 on the same protrusion 221. After the output shaft 12 and the input shaft 22 are assembled and connected, the second chamfer 225 is in interference fit with the first chamfer 124, making the connection between the input shaft 22 and the output shaft 12 tighter.

[0023] In one embodiment, the angle between the two guide surfaces 122 on the same boss 121 is 10° - 120°.

[0024] In this embodiment, the angle between two guide surfaces 122 on the same boss 121 is 10° to 120°, for example, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110° or 120°. Of course, it may be any angle within the above range, and the present application does not limit this further. The larger the angle, the more difficult it is to assemble the treatment head 2, but the connection becomes more stable. The smaller the angle, the easier it is to assemble the treatment head 2, but the connection becomes less stable.

[0025] In one embodiment, the guide surface 122 includes a guide inclined surface or a guide curved surface.

[0026] In this embodiment, the guide surface 122 is a guide inclined surface that can press against the guide rib 223 to push the input shaft 22 to rotate, and it may also be a flat surface. The guide surface 122 may also be a guide curved surface. It should be understood that by designing the curvature of the curved surface and the angle of the guide rib 223, it is also possible to realize that the guide curved surface presses against the guide rib 223 to push the input shaft 22 to rotate.

[0027] In one embodiment, a first safety plane 125 is provided at the intersection of two guide surfaces 122 on the same boss 121, and the width of the first safety plane 125 is 0.01 to 2 mm.

[0028] In this embodiment, in order to prevent the intersection of the two guide surfaces 122 from being sharp and causing injury to the operator, a first safety plane 125 is provided at the intersection of the two guide surfaces 122 to blunt the sharp corner and prevent the operator from being injured. The width of the first safety plane 125 adopts 0.01 to 2 mm, for example, 0.01 mm, 0.08 mm, 0.4 mm, 1 mm, 1.5 mm, 2 mm, etc. Of course, it may be any value within the above range, and the present application does not limit this further.

[0029] In one embodiment, two cutting slopes 226 forming an angle are formed on each protrusion 221. A guide rib 223 is provided at the connection location between one cutting slope 226 and one second transmission slope 224. A second safety plane 227 is provided at the connection location between the two cutting slopes 226, and the width of the second safety plane 227 is 0.01 - 2 mm.

[0030] In this embodiment, two cutting slopes 226 forming an angle are formed on the protrusion 221, and the guide rib 223 is provided at the connection location between one cutting slope 226 and one second transmission slope 224, thereby facilitating processing. The guide rib 223 is formed by processing the protrusion 221. A second safety plane 227 is provided at the connection location between the two cutting slopes 226, which can prevent sharp corners from hurting the operator. The width of the second safety plane 227 adopts 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, any value within the above range may be used, and the present application is not limited thereto.

[0031] The present application further proposes an installation method applicable to the treatment handle 10 as described above. Step S1 of controlling the guide surface 122 to abut against the guide rib 223; Step S2 of controlling the guide surface 122 to move along the guide rib 223.

[0032] In this embodiment, first, the guide surface 122 is controlled to abut against the guide rib 223 to achieve a preliminary guiding effect for initially connecting the output shaft 12 and the input shaft 22. Then, the guide surface 122 is controlled to move along the guide rib 223, thereby realizing the movement of the output shaft 12 relative to the input shaft 22, achieving a rapid connection between the output shaft 12 and the input shaft 22, and improving work efficiency.

[0033] In one embodiment, the guide surface 122 includes a plurality of bosses protruding convexly at the first end, the plurality of bosses are provided at intervals along the circumferential direction of the output shaft 12, each boss is provided to extend along the radial direction of the output shaft 12, two guide surfaces are formed at the end of the boss close to the treatment head 2, the guide rib 223 includes a plurality of protrusions provided at the other end of the input shaft 12, the plurality of protrusions are distributed at intervals along the circumferential direction of the input shaft 12, and two adjacent protrusions surround to form a receiving groove for receiving the boss. Two guide ribs 223 are respectively formed on both sides of each protrusion. The mounting method is controlling to bring the guide surface into contact with the guide rib 223; and controlling to move the guide surface along the guide rib 223.

[0034] In one embodiment, the treatment handle 10 further includes an output shaft 12 control assembly. Before the step of controlling the guide surface 122 to contact the guide rib 223, it further includes a step S1' of controlling the output shaft 12 control assembly to lock the output shaft 12.

[0035] In this embodiment, an output shaft 12 control assembly is further provided at the end of the treatment handle 10. Before controlling the guide surface 122 to abut against the guide rib 223, the output shaft 12 control assembly is controlled to lock the output shaft 12 so that it cannot rotate, preventing the output shaft 12 from being pushed by the input shaft 22 to cause misalignment and connection failure. The output shaft 12 control assembly may be a combination of a shaft sleeve and a photoelectric sensor. One end of the shaft sleeve is fitted onto the drive shaft of the drive assembly 11, the other end is connected to the output shaft 12, and a flapper is provided on the outer peripheral wall of the shaft sleeve. The flapper has two states: a state of blocking the optical path of the photoelectric sensor and a state of avoiding the optical path of the photoelectric sensor. The output shaft 12 is preset to be in a corrected state when the optical path of the photoelectric sensor is blocked. When the photoelectric sensor cannot detect the optical signal, it indicates that the output shaft 12 is in the initial state at this time. At this time, the photoelectric sensor controls the drive assembly 11 to lock the drive shaft, and thus locks the output shaft 12, and the output shaft 12 and the input shaft 22 are directly assembled and connected. Note that the output shaft 12 control assembly may be other devices, such as an angle sensor, which determines and controls whether it is in the initial state by detecting the change in the angle of the output shaft 12.

[0036] 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 a linear reciprocating motion of the transducer body 212. The transducer body 212 has an initial mounting position. After the step of controlling the guide surface 122 to move along the guide rib 223, The method further includes a step S3 of controlling the transducer body 212 to return to the initial mounting position.

[0037] In this embodiment, the transducer assembly 21 includes a transducer motion assembly 19 and a transducer body 212. The rotary motion part 211 is connected to the input shaft 22 and can convert the circumferential rotation of the input shaft 22 into a linear reciprocating motion, thereby driving the transducer body 212 to perform a linear reciprocating motion. The transducer motion assembly 19 may be a crank-slider mechanism or a combination of a missing-tooth gear and a rack, but the present application is not limited thereto any further. When the locked output shaft 12 is connected to the input shaft 22, the first guide slope can press against the second guide slope, thereby driving the input shaft 22 to rotate. The input shaft 22 also rotates to the correction state. Subsequently, the transducer motion assembly 19 is driven to move together with the transducer body 212 so that the transducer body 212 returns directly below the input shaft 2 to the initial position, facilitating the next treatment.

[0038] The present application further proposes a treatment handle 10. Referring to FIGS. 7 to 9 in combination, it 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 and is used 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 input shaft to rotate, and the input shaft drives the transducer assembly 21 to perform a linear movement.

[0039] In this embodiment, a sensor assembly 6 for detecting the position state of the drive shaft 20 of the drive assembly 11 is provided on the handle body 24 of the treatment handle 10, and is electrically connected to the drive assembly 11, automatically controlling the drive shaft 20 of the drive assembly 11 to rotate to a specified position, and stopping and locking the drive shaft 20 at an appropriate timing, and then aligning and connecting it with the input shaft of the treatment head. As a result, it is no longer necessary to repeatedly perform manual calibration, and labor costs and time costs can be saved. The sensor assembly 6 may employ a hall sensor provided on the outer peripheral wall of the drive shaft 20, and by measuring the rotation angle of the drive shaft 20, it is determined whether the position of the drive shaft 20 has been corrected. A photoelectric sensor may also be employed, and a notched convex plate for blocking the reception of the optical signal of the photoelectric sensor is provided around the outer peripheral wall of the drive shaft 20. The correction position of the drive shaft 20 is set such that when the photoelectric sensor receives the optical signal, the drive shaft 20 is at the correction position, and automatic correction of the drive shaft 20 can also be realized. The present application is not limited further herein. The drive assembly 11 is a motor assembly commonly seen in the market, and the model and specifications should be specifically selected based on the specifications of the treatment handle 10 and the requirements for the rotation speed. The present application is not further limited thereto.

[0040] The technical solution of the present application is to employ a sensor assembly 6 to detect the rotation angle state of the drive shaft 20 of the drive assembly 11, and to be electrically connected to the drive assembly 11, controlling the drive shaft 20 of the drive assembly 11 to rotate or stop at an appropriate timing, thereby realizing automatic correction of the drive shaft 20 of the handle body 24, and being able to lock the drive shaft 20 after the drive shaft 20 rotates to the correction position, realizing the rapid attachment of the handle body 24 and the treatment head, and saving labor costs and time costs.

[0041] In one embodiment, the handle body 24 further includes a first position limiting portion 5 for limiting the rotation angle of the drive shaft 20.

[0042] In this embodiment, a first position limiting portion 5 for limiting the rotation angle of the drive shaft 20 is provided on the handle body. When the drive shaft 20 abuts against the first position limiting portion 5 and can no longer continue to rotate, the rotation position of the drive shaft 20 at this time is set as the correction position. Then, it is only necessary to control the drive shaft 20 of the drive assembly 11 by the sensor assembly 6 to rotate until it abuts against the first position limiting portion 5. Thereby, the step of detecting the current rotation angle of the drive shaft 20 is omitted, the speed of correcting the drive shaft 20 is further improved, and thus the handle body 24 and the treatment head are quickly connected, saving labor costs and time costs.

[0043] In one embodiment, the transducer assembly 21 includes a transducer motion assembly 21 and a transducer body 212. One side of the transducer motion assembly 21 is connected to the other end of the input shaft, and the other side is connected to the transducer body, converting the rotational motion of the input shaft into a linear reciprocating motion of the transducer body.

[0044] 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 a linear reciprocating motion, thereby driving the transducer body 212 to perform a linear reciprocating motion and realizing a planar treatment effect. The transducer motion assembly 21 may be a crank-slider mechanism or a combination of a missing-tooth gear and a rack, but the present application is not limited thereto any further here.

[0045] In one embodiment, the transducer body 212 has a preset position. When the drive shaft 20 in the correction position is connected to the input shaft, the transducer body 212 returns to the preset position.

[0046] In this embodiment, in order to facilitate subsequent treatment, for the transducer body 212, a preset position may be set, and the preset position may be the intermediate position of the treatment head, one side of the treatment head, or any position, but it is not further limited here. When the drive shaft 20 at the correction position is connected to the input shaft, the drive shaft 20 is locked, driving the input shaft to rotate, and thus driving the transducer motion assembly 21 to move, and further driving the transducer body 212 to move, so as to return it to the preset position.

[0047] In one embodiment, the treatment head further includes a second position limiting part (not shown) for limiting the displacement distance of the transducer body 212.

[0048] In this embodiment, by providing a second position limiting part for limiting the displacement distance of the transducer body 212 on the treatment head, it is possible to prevent the transducer body 212 from becoming immovable due to excessive displacement.

[0049] As shown in FIGS. 7 to 9, in one embodiment, the handle body 24 further includes a shaft sleeve 3. One end of the shaft sleeve 3 is fitted to the drive shaft 20, and a blocking part 31 is provided on the outer peripheral wall of the shaft sleeve 3. The sensor assembly 6 is a photoelectric sensor assembly 332, and the photoelectric sensor assembly 332 is provided close to the shaft sleeve 3. The blocking part 31 has a first state of blocking the optical signal of the photoelectric sensor assembly 332 and a second state of avoiding the optical signal of the photoelectric sensor assembly 332.

[0050] In this embodiment, the photoelectric sensor assembly 332 is used as the sensor assembly 6 for detecting the position state of the drive shaft 20. At the same time, a shaft sleeve 3 is fitted on the outer periphery of the drive shaft 20. The shaft sleeve 3 can rotate together with the drive shaft. A blocking portion 31 is provided on the outer peripheral wall of the shaft sleeve 3. When the blocking portion 31 is in the first state, the reception of the optical signal of the photoelectric sensor can be blocked. When the blocking portion 31 is in the second state, the optical signal of the photoelectric sensor can be avoided. The position of the shaft sleeve 3 is preset. When the blocking portion 31 is in the first state, the position of the drive shaft 20 at this time is defined as the correction position. If it is necessary to correct the position of the drive shaft 20, the photoelectric sensor determines whether it has received an optical signal. If it has received an optical signal, it indicates that the blocking portion 31 is in the second state at this time and the position of the drive shaft 20 is not the correction position. Until the photoelectric sensor can no longer receive the optical signal, the drive assembly 11 is controlled to drive the drive shaft 20 to rotate. If the optical signal cannot be received, it indicates that the blocking portion 31 is in the first state at this time and the position of the drive shaft 20 is at the correction position, and there is no need to correct it. The material of the shaft sleeve 3 may be a metal material, such as stainless steel or titanium alloy, or may be an engineering plastic, but it is not further limited here. On the premise that the optical signal can be blocked, it can be understood that the shorter the length of the blocking portion 31, the more accurate the position correction of the drive shaft 20 will be. The specific length should be selected by oneself according to the actual needs, but it is not further limited in this application.

[0051] In one embodiment, referring to FIG. 9, there are two blocking portions 31, and the two blocking portions 31 are symmetrically arranged on the outer peripheral wall of the shaft sleeve 3.

[0052] In this embodiment, since the drive shaft 20 generally has a cylindrical structure and the tip portion has a centrosymmetric structure, the correction position of the drive shaft 20 is not unique. Therefore, by symmetrically arranging the two blocking portions 31 on the outer peripheral wall of the shaft sleeve 3, the time required for correcting the drive shaft 20 can be shortened, the time cost can be further saved, and the efficiency can be improved. Referring to FIGS. 7 and 8, in one embodiment, the handle body 24 further includes a housing (not shown) and a bracket 4.

Both the housing and the bracket 4 may be made of a metal material such as aluminum alloy or titanium alloy, or may be made of a material such as hard engineering plastic, and will not be further limited herein.

[0056] This application further proposes an ultrasonic therapeutic apparatus (not shown). The ultrasonic therapeutic apparatus includes a treatment handle 10. For the specific structure of the treatment handle 10, reference is made to the above embodiments. Since this ultrasonic therapeutic apparatus adopts all the technical solution means of the above all embodiments, it has at least all the beneficial effects brought about by the technical solution means of the above embodiments, but this will not be described again here.

[0057] An embodiment of this application proposes a treatment head 2. Referring to FIGS. 10 and 11 in combination, it includes an input shaft 22, a transducer motion assembly 19, and a transducer 18 (the same as the transducer body 212 in the previous 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 rotary motion part 211 and a linear motion part 1222. The rotary motion part 211 is drivingly connected to the other end of the input shaft 22 away from the output shaft 12. The linear motion part 1222 is drivingly connected to the rotary motion part 211. The transducer 18 is connected to the linear motion part 1222. The input shaft 22 drives the rotary motion part 211 to rotate, and the rotary motion part 211 drives the linear motion part 1222 that moves linearly to linearly move the transducer 18.

[0058] In this embodiment, the input shaft 22 is used to transmit the driving force from the output shaft 12 of the driving assembly 11. One end of the input shaft 22 is connected to the output shaft 12. Since the rotational speeds of the input shaft 22 and the output shaft 12 are relatively low, a direct connection method may be adopted for the connection method, or other connection methods such as coupling or key connection may be adopted, as long as the input shaft 22 can follow the output shaft 12 and rotate together. The present application does not further limit this. The transducer motion assembly 19 includes a rotary motion part 211 and a linear motion part 1222. The rotary motion part 211 is connected to the other end of the input shaft 22. The connection method between the rotary motion part 211 and the input shaft 22 may be a screw connection, or may be engagement or welding, as long as the rotary motion part 211 can rotate together with the input shaft 22. The present application does not further limit this.

[0059] The rotary motion part 211 is drivingly connected to the linear motion part 1222, and the rotary motion of the rotary motion part 211 can be converted into the linear motion of the linear motion part 1222. As a result, the transducer 18 connected to the linear motion part 1222 is driven to perform a linear reciprocating motion. The combination of the rotary motion part 211 and the linear motion part 1222 may be a crank-slider structure. The crank and the slider are connected, and a sliding groove is installed to limit the motion locus of the slider to be linear. The input shaft 22 drives the crank to rotate together, and then drives the slider to perform a linear reciprocating motion along the sliding groove, and then drives the transducer 18 to perform a linear reciprocating motion.

[0060] In one embodiment, the combination of the rotary motion part 211 and the linear motion part 1222 may be a combination of a spur gear with missing teeth and a rack. Two racks are symmetrically arranged on both sides of the spur gear with missing teeth, and both racks are movable. When the spur gear with missing teeth is driven by the input shaft 22 to rotate in one direction and the tooth part of the spur gear with missing teeth meshes with the tooth part of one rack, the rack moves along the tangential direction of the rotation direction of the spur gear with missing teeth. When the tooth part of the spur gear with missing teeth rotates to the opposite side, it meshes with the tooth part of the other rack and drives the rack to move along the tangential direction of the rotation direction of the spur gear with missing teeth. Since the rotation directions on both opposite sides of the spur gear with missing teeth are opposite, the linear reciprocating motion of the rack can be realized.

[0061] In one embodiment, the combination of the rotary motion part 211 and the linear motion part 1222 may be a combination of a gear and a rack. In this case, the input shaft 22 needs to have a periodic bidirectional rotary motion state. The tooth part of the gear meshes with the tooth part of the rack, and the input shaft 22 drives the gear to perform a periodic bidirectional rotary motion, and thus drives the rack and the transducer 18 connected thereto to perform a linear reciprocating motion. The combination of the rotary motion part 211 and the linear motion part 1222 is not unique, as long as the rotary motion of the input shaft 22 can be converted into the linear reciprocating motion of the transducer 18, and no further limitation is imposed here.

[0062] The treatment head 2 proposed by the technical solution of the present application includes an input shaft 22, a transducer motion assembly 19, and a transducer 18. The transducer motion assembly 19 further includes a rotary motion part 211 and a linear motion part 1222. The output shaft 12 of the drive assembly 11 is connected to the input shaft 22 to transmit the power of the drive assembly 11 to the input shaft 22 of the treatment head 2. Next, the input shaft 22 is drivingly connected to the rotary motion part 211 to rotate it. Finally, the linear motion part 1222 is driven to convert the rotary motion of the input shaft 22 into a linear reciprocating motion of the linear motion part 1222. The transducer 18 is connected to the linear motion part 1222 and performs a linear reciprocating motion following and together with the linear motion part 1222, thereby realizing planar treatment of the treatment head 2 and saving labor costs. The treatment head 2 proposed in the present application realizes the lateral movement of the transducer 18 through the combination of the rotary motion part 211 and the linear motion part 1222, has a simple and compact structure, and high transmission efficiency.

[0063] Referring to FIG. 11, in one embodiment, the input shaft 22 drives the rotary motion part 211 to reciprocate in both directions. A plurality of first tooth parts 1211 are provided on the side of the rotary motion part 211 facing the linear motion part 1222. A plurality of second tooth parts 1221 are provided on the surface of the linear motion part 1222 facing the rotary motion part 211. The plurality of first tooth parts 1211 are engaged and connected with the plurality of second tooth parts 1221 to drive the linear motion part 1222 to perform a linear reciprocating motion.

[0064] In this embodiment, the output shaft 12 of the drive assembly 11 has a periodic bidirectional rotation state. A plurality of first tooth portions 1211 are provided on one side of the rotary motion portion 211. On the surface of the linear motion portion 1222 facing the rotary motion portion 211, a plurality of second tooth portions 1221 that mesh with the first tooth portions 1211 are provided. Through the meshing of the first tooth portions 1211 and the second tooth portions 1221, the rotary motion portion 211 drives the linear motion portion 1222 to move along the tangential direction of the rotation of the rotary motion portion 211. Since the rotary motion portion 211 performs a periodic bidirectional rotary motion together with the drive of the input shaft 22, the linear motion portion 1222 and the transducer 18 connected to the linear motion portion 1222 are driven by the rotary motion portion 211 to perform a horizontal linear reciprocating motion, realizing the planar scanning treatment of the treatment head 2. The transmission method by the meshing of the tooth portions has high transmission efficiency. Specifically, the lengths of the first tooth portions 1211 and the second tooth portions 1221, as well as the specific parameters of the tooth portions, such as the number of tooth portions or the tooth portion coefficient, etc., should be selected by oneself according to specific needs, but this application does not further limit this. As the materials of the linear motion portion 1222 and the rotary motion portion 211, they may be lightweight engineering plastics with self-lubricating properties, or may be metal materials such as stainless steel or aluminum alloy that are strong and wear-resistant. This application does not further limit this.

[0065] Referring to FIG. 11 again, in one embodiment, on the other side of the rotary motion portion 211 away from the first tooth portion 1211, a position limiting groove 1212 extending in the circumferential direction is formed. The treatment head 2 further includes a position limiting portion 14. One end of the position limiting portion 14 is provided on the transducer 18, and the other end is exposed from the position limiting groove 1212 to limit the rotation angle of the rotary motion portion 211.

[0066] In this embodiment, on the other side of the first tooth portion 1211 of the rotary motion portion 211 away from it, a position limiting groove 1212 is formed. The position limiting groove 1212 extends along the circumferential direction of the rotary motion portion 211. Further, a position limiting portion 14 is provided. The position limiting portion 14 is provided in the position limiting groove 1212 to limit the rotation angle of the rotary motion portion 211, preventing the motion distance of the linear motion portion 1222 from being too long due to the rotation angle of the rotary motion portion 211 being too large, which may cause a collision with the housing or other components and damage the device. Regarding the specific length of the position limiting groove 1212 and the mounting position of the position limiting portion 14, it should be determined according to actual needs by oneself and will not be further limited herein. In other embodiments, it should be understood that by adjusting and controlling the rotation speed and rotation period of the drive assembly 11, the rotation angle and rotation period of the rotary motion portion 211 can also be controlled, and thus the moving distance and reciprocating frequency of the linear motion portion 1222 can be controlled.

[0067] In one embodiment, as shown in conjunction with FIG. 11, there are two linear motion portions 1222. The two linear motion portions 1222 are symmetrically arranged on both sides of the rotary motion portion 211, and both sides of the transducer 18 are respectively connected to the two linear motion portions 1222.

[0068] In this embodiment, two linear motion portions 1222 are symmetrically arranged on both sides of the rotary motion portion 211. Both sides of the transducer 18 are respectively connected to the two linear motion portions 1222, making the connection between the transducer 18 and the linear motion portion 1222 more stable and the motion of the transducer 18 smoother. In other embodiments, by providing the position limiting portion 14 and the position limiting groove 1212, the rotary motion portion 211 meshes and connects with only one side of the linear motion portion 1222. Therefore, it should be understood that a connection bar without teeth can be provided on the other side of the rotary motion portion 211, thereby achieving the effect of making the connection more stable and the motion of the transducer 18 smoother.

[0069] In one embodiment, referring also to FIG. 11, the output shaft 12 can drive the rotary motion part 211 to rotate in one direction. A plurality of third tooth parts (not shown) are provided on a part of the side of the rotary motion part 211 facing the linear motion part 1222. There are two linear motion parts 1222, and the two linear motion parts are symmetrically arranged on both sides of the rotary motion part 211. A plurality of fourth tooth parts (not shown) are provided on the surfaces of the two linear motion parts 1222 facing the rotary motion part 211. The plurality of third tooth parts are engaged and connected with the plurality of fourth tooth parts 1222 to drive the two linear motion parts 1222 to perform a linear reciprocating motion.

[0070] In this embodiment, the output shaft 12 of the drive assembly 11 rotates in one direction, drives the input shaft 22 of the treatment head 2 to rotate in one direction, and thus drives the rotary motion part 211 to rotate in one direction. The two linear motion parts 1222 are symmetrically arranged on both sides of the rotary motion part 211. The rotary motion part 211 rotates in one direction. The plurality of third tooth parts of the rotary motion part 211 are engaged with the fourth tooth parts of the linear motion part 1222 on one side, and the two linear motion parts 1222 are driven to linearly move 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 is engaged with the fourth tooth parts of the other linear motion part 1222, the two linear motion parts 1222 are driven to perform a linear motion in the direction opposite to the previous direction along the tangential direction of the rotation of the rotary motion part 211. Then, the above process is repeated to linearly reciprocate the transducer 18 and realize the planar treatment effect of the treatment head 2. The transmission method by the engagement of the tooth parts has high transmission efficiency. Specifically, the lengths of the third tooth parts and the fourth tooth parts, and the specific parameters of the tooth parts, such as the number of tooth parts or the coefficient of the tooth parts, etc., should be selected by oneself according to specific needs, but the present application does not further limit this. As the materials of the linear motion part 1222 and the rotary motion part 211 according to this embodiment, they may be lightweight and self-lubricating engineering plastics, or may be metal materials such as stainless steel or aluminum alloy that are strong and wear-resistant. The present application does not further limit this.

[0071] Referring to FIG. 10, in one embodiment, the treatment head 2 further 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 for connecting to the linear motion portion 1222, the clamping portion 172 is connected to the other surface of the fixing portion 171 away from the linear motion portion 1222, and the clamping portion 172 is used for clamping the transducer 18.

[0072] In this embodiment, the transducer bracket 17 is arranged to connect the linear motion portion 1222 and the transducer 18, so that the transducer 18 can be stably connected. The transducer bracket 17 includes a fixing portion 171 and a clamping portion 172. The fixing portion 171 is used for connecting to the linear motion portion 1222, and the clamping portion 172 is connected to the surface of the fixing portion 171 away from the linear motion portion 1222. The connection method may adopt screw connection or welding, etc., and will not be further limited here. The clamping portion 172 is used for clamping the transducer 18, and it is easier to remove and replace the transducer 18 compared with other connection methods.

[0073] In one embodiment, referring to FIG. 10 together, the treatment head 2 further includes a mounting base 15. A relief hole 151 is opened 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. A seal member 152 is provided between the input shaft 22 and the mounting base 15.

[0074] In this embodiment, a mounting base 15 is provided on the treatment head 2. A relief hole 151 for passing the input shaft is formed in the mounting base 15. It can be driven by the output shaft 12 to perform a rotational motion. As a result, the input shaft 22 drives the rotational motion part 211 and the linear motion part 1222 to convert the rotational motion of the output shaft 12 into a lateral reciprocating motion of the transducer 18, thereby realizing the planar treatment of the treatment head 2. Since the transducer 18 needs to use a medium for transmitting sound to contribute to the transmission of ultrasonic waves during the working process, it is necessary to provide a sealing member 152 for sealing the treatment head 2 between the input shaft 22 and the mounting base 15 to prevent the medium for transmitting sound from leaking and affecting the operating effect of the transducer 18. The sealing member 152 may employ a sealing ring or a sealing strip, etc., and may also adopt a sealing method such as caulking, but the present application does not further require this. The mounting base 15 may adopt a hard plastic, or may adopt a metal material such as an aluminum alloy, but it is not further limited here.

[0075] In one embodiment, referring to FIGS. 10 and 11 together, the treatment head 2 further includes a guide rail 16. The guide rail 16 is provided on a surface of the mounting base 15 away from the output shaft 12. The other side of the linear motion part 1222 away from the rotational motion part 211 is slidably connected to the guide rail 16 and linearly moves along the extending direction of the guide rail 16.

[0076] In order to control the movement locus of the linear motion part 1222 and thus control the movement locus of the transducer 18, in this embodiment, a guide rail 16 is provided on the surface of the mounting base 15 away from the drive shaft. The guide rail 16 is slidably connected to the other side of the rotary motion part 211 of the linear motion part 1222 away from it. Thereby, the linear motion part 1222 only performs a linear reciprocating motion along the guide rail 16. In addition, convex strips may be provided on the guide rail 16, grooves may be provided on the other side of the rotary motion part 211 of the linear motion part 1222 away from it, and the convex strips may be slidably installed in the grooves.

Grooves may be provided on the guide rail 16, convex strips may be provided on the other side of the rotary motion part 211 of the linear motion part 1222 away from it, and the convex strips may be slidably installed in the grooves. Thereby, the linear motion part 1222 can be linearly moved along the guide rail 12, and the present application does not further limit this here.

[0077] The present application further proposes a treatment handle. The treatment handle (not shown) includes a handle body 1 and a treatment head 2. The specific structure of the treatment head 2 refers to the above embodiments. Since this treatment handle adopts all the technical solution means of all the above embodiments, it has at least all the beneficial effects brought about by the technical solution means of the above embodiments, but this will not be described again here. The handle body 1 includes a drive assembly 11. The treatment head 2 is the treatment head 2 described in any of the above embodiments.

Regarding the first guide member of the output shaft 12 and the second guide member of the input shaft 22, the connection and attachment of the first guide member and the second guide member are in any mechanical connection manner.
