Detailed Implementation

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] This utility model embodiment provides a linear treatment head, see [link]. Figure 1 and combined Figures 2 to 9 The linear treatment head includes: a handle housing 1, a power assembly 2, a push rod 3, a transducer assembly, an elastic element 7, and a treatment head housing 8;

[0054] The first end of the handle housing 1 is detachably connected to the first end of the treatment head housing 8;

[0055] The power unit 2 is located inside the handle housing 1;

[0056] The first end of the handle housing 1 has a first opening for the push rod 3 to pass through, and the first end of the treatment head housing 8 has a second opening for the push rod 3 to pass through;

[0057] The transducer assembly is movably disposed within the treatment head housing 8;

[0058] The transducer bracket assembly has a mating port 51 that engages with the first end of the push rod 3;

[0059] The second end of the push rod 3 is connected to the power component 2 for transmission. The power component 2 is used to drive the push rod 3 to reciprocate along the axial direction of the push rod 3.

[0060] The elastic element 7 is disposed inside the treatment head housing 8, and the elastic element 7 can generate elastic deformation when the transducer assembly is away from the power assembly 2.

[0061] It should be noted that, since the transducer assembly is engaged with the first end of the push rod 3, and the elastic element 7 is located inside the treatment head housing 8, the elastic element 7 can undergo elastic deformation when the transducer assembly moves away from the power assembly 2. Therefore, when the power assembly 2 drives the push rod 3 to move towards the treatment head housing 8, the push rod 3 will drive the transducer assembly away from the power assembly 2 and cause the elastic element 7 to undergo elastic deformation. At this time, the elastic element 7 is in an energy storage state. When the power assembly 2 drives the push rod 3 to move towards the power assembly 2, the push rod 3 will drive the transducer assembly closer to the power assembly 2. At this time, the elastic element 7 provides an elastic restoring force for the transducer assembly, causing the transducer assembly to follow the push rod 3 to move towards the first end of the power assembly 2, effectively preventing the transducer assembly from separating from the push rod 3.

[0062] It is worth noting that the elastic element of this application can undergo tensile deformation or compressive deformation when the transducer assembly is far away from the power assembly 2.

[0063] It should also be noted that the snap-fit ​​is an interlocking assembly structure. In this application, the transducer assembly and the first end of the push rod 3 are snap-fitted together, so that the connection between the transducer assembly and the push rod 3 has a certain strength and can be easily disassembled and assembled during later maintenance.

[0064] In this embodiment of the invention, the first end of the handle housing 1 is detachably connected to the first end of the treatment head housing 8. A power assembly 2 is disposed within the handle housing 1, and a first opening for the push rod 3 to pass through is provided at the first end of the handle housing 1. A second opening for the push rod 3 to pass through is provided at the first end of the treatment head housing 8. A transducer assembly is movably disposed within the treatment head housing 8, and the transducer assembly has a mating opening 51 for engaging with the first end of the push rod 3. The second end of the push rod 3 is connected to the power assembly 2. An elastic element 7 is disposed within the treatment head housing 8, and the elastic element 7 can undergo elastic deformation when the transducer assembly moves away from the power assembly 2. Through the aforementioned handheld assembly, the engagement of the push rod 3 with the transducer assembly not only allows the motor assembly to drive the transducer assembly to perform reciprocating linear motion within the handle housing 1, but also effectively prevents the transducer assembly from disengaging from the push rod 3 when the motor assembly drives the push rod 3 towards the first end of the handle housing 1.

[0065] Specifically, it is fitted with port 51 as the fastener;

[0066] The first end of the push rod 3 is provided with a groove structure 31 that engages with the latch.

[0067] It should be noted that the mating port 51 is a snap-fit ​​position, and a groove structure 31 that mates with the snap-fit ​​position is provided at the first end of the push rod 3. The connection between the push rod 3 and the transducer assembly can be achieved by the snap-fit ​​position and the groove structure 31 engaging.

[0068] It should also be noted that the mating port 51 can be set as a snap-fit, and the first end of the push rod 3 can be set as a groove structure 31 that mates with the snap-fit. Alternatively, the mating port 51 can be set as a groove structure 31, and the first end of the push rod 3 can be set as a snap-fit ​​that mates with the groove structure 31. Those skilled in the art can choose according to their needs.

[0069] Furthermore, the first end of the push rod 3 is also provided with a limiting flange 32.

[0070] It should be noted that by setting a limiting flange 32 at the first end of the push rod 3, when the push rod 3 drives the transducer assembly to move towards the second end of the handle housing 1, it can play a role in limiting the engagement when the mating port 51 of the transducer assembly is engaged with the push rod 3.

[0071] Specifically, the power assembly 2 includes: a power mechanism 21, a mounting bracket 22, a slider 23, a linear guide rail 24, and a lead screw 25;

[0072] The power mechanism 21 and the linear slide rail 24 are mounted on the mounting bracket 22;

[0073] The slider 23 is slidably mounted on the linear slide rail 24, and the slider 23 has a threaded hole that engages with the lead screw 25.

[0074] One end of the lead screw 25 is connected to the power mechanism 21 for transmission.

[0075] The second end of push rod 3 is connected to slider 23.

[0076] It should be noted that the power mechanism 21 and the linear slide rail 24 are mounted on the mounting bracket 22, and the slider 23 is slidably mounted on the linear slide rail 24. The slider 23 has a threaded hole that engages with the lead screw 25. One end of the lead screw 25 is connected to the power mechanism 21 for transmission, and the second end of the push rod 3 is connected to the slider 23. Thus, when the power mechanism 21 drives the lead screw 25 to rotate, the lead screw 25 can drive the slider 23 to slide on the linear slide rail 24 through the threaded engagement with the slider 23. Since the second end of the push rod 3 is connected to the slider 23, when the slider 23 reciprocates on the linear slide rail 24, the push rod 3 can drive the transducer assembly to reciprocate within the handle housing 1.

[0077] Preferably, the mounting bracket 22 includes a motor mounting bracket 221, a motor support bracket 222, and an electrical mounting bracket 223.

[0078] The motor mounting bracket 221 is disposed on one side of the motor bracket 222, and the motor is disposed on the motor mounting bracket 221;

[0079] Electrical mounting bracket 223 is mounted on motor bracket 222;

[0080] The linear guide rail 24 is mounted on the motor bracket 222.

[0081] Preferably, a motor stop 224 is provided on the other side of the motor bracket 222 and is located at the other end of the lead screw 25.

[0082] It should be noted that by providing a motor stop 224 on the other side of the motor bracket 222 and positioning the motor stop 224 at the other end of the lead screw 25, the slider 23 can be effectively prevented from coming off the other end of the lead screw 25.

[0083] Preferably, the power mechanism 21 is a brushless motor;

[0084] The lead screw 25 is connected to the shaft of the brushless motor via a coupling 26.

[0085] It should be noted that connecting the lead screw 25 to the shaft of the brushless motor via the coupling 26 effectively ensures the connection strength between the brushless motor and the lead screw 25, thereby ensuring that the slider 23 can reciprocate on the linear slide rail 24 following the rotation of the lead screw 25.

[0086] Preferably, the top of the transducer bracket 5 is provided with a magnet 86 for sensing and positioning.

[0087] Specifically, the elastic element 7 is a spring.

[0088] It should be noted that the elastic element 7 can be a spring or other components that can produce elastic deformation under external force (such as a spring sheet). Those skilled in the art can choose according to their needs.

[0089] In some embodiments, the transducer assembly includes: a transducer 4 and a transducer support 5;

[0090] Transducer 4 is mounted on transducer bracket 5;

[0091] The transducer 4 is provided with a mating port 51 that engages with the first end of the push rod 3;

[0092] The elastic element 7 is disposed between the transducer 4 and the treatment head housing 8.

[0093] It should be noted that, in the internal structure of an ultrasonic therapy device, when the motor assembly drives the treatment head to extend and retract via a push rod to adjust the ultrasonic focal length, placing the elastic element 7 between the transducer 4 and the treatment housing 8 can effectively prevent the push rod 3 from becoming loose from the transducer support 5.

[0094] It is worth noting that the transducer 4 is mounted on the transducer support 5, so when the transducer support 5 moves, it can drive the transducer 4 to move.

[0095] It should also be noted that the elastic element 7 of this application can be set in a specific position along the moving direction of the push rod 3, can be set on the side of the transducer 4 away from the push rod 3, or can be set on the side of the transducer 4 close to the push rod 3, that is, the two ends of the elastic element 7 are respectively fixed to the transducer 4 and the treatment head housing 8, or can be set on both sides of the transducer 4 at the same time.

[0096] The elastic element 7 of this application can produce elastic deformation when stretched or compressed. If the elastic element 7 is set on the side of the transducer 4 close to the push rod 3, when the push rod 3 extends towards the treatment head, it drives the transducer 4 away from the handle housing 1. At this time, the elastic element 7 is under tensile deformation. When the push rod 3 retracts, the elastic element 7 drives the transducer 4 closer to the handle housing 1 through its own elastic restoring force, ensuring that the push rod 3 is connected to the transducer bracket 5 and preventing loosening.

[0097] By placing the elastic element 7 on the side of the transducer 4 away from the push rod 3, when the push rod 3 extends towards the treatment head, it drives the transducer 4 away from the handle housing 1. The transducer 4 squeezes the elastic element 7, causing the elastic element 7 to be in a state of compression deformation. When the push rod 3 retracts, the elastic element 7 uses its own elastic restoring force to drive the transducer 4 closer to the handle housing 1, ensuring that the push rod 3 is connected to the transducer bracket 5 and preventing it from becoming loose.

[0098] In other embodiments, such as Figures 1 to 9 The handheld component also includes: a support guide post 6;

[0099] The guide post 6 is disposed inside the treatment head housing 8 and is parallel to the push rod 3;

[0100] The transducer assembly includes: transducer 4 and transducer support 5;

[0101] The transducer 4 is mounted on the transducer bracket 5, and the transducer bracket 5 has a mating opening 51 for engaging with the first end of the push rod 3.

[0102] The transducer bracket 5 has a through hole for the bracket guide post 6 to pass through;

[0103] The spring is sleeved on the guide post 6 of the bracket.

[0104] It should be noted that by setting the guide post 6, the transducer support 5 can be ensured to move back and forth within the treatment head along the guide post 6.

[0105] It is worth noting that when the spring is sleeved on the guide post 6 of the support, it can be set on the side of the transducer support 5 away from the push rod 3, or it can be set on the side closer to the push rod 3. However, both ends of the spring need to be fixed to the treatment head housing 8 and the transducer support 5 respectively. Alternatively, it can be set on both sides of the transducer support 5. Those skilled in the art can choose according to their needs.

[0106] If the elastic element 7 is placed on the side of the transducer bracket 5 close to the push rod 3, when the push rod 3 extends towards the treatment head, it will drive the transducer 4 and the transducer bracket 5 away from the handle housing 1. At this time, the elastic element 7 is under tension deformation. When the push rod 3 retracts, the elastic element 7 will drive the transducer bracket 5 closer to the handle housing 1 through its own elastic restoring force, so as to ensure that the push rod 3 is connected to the transducer 4 and avoid loosening.

[0107] Placing the elastic element 7 on the side of the transducer bracket 5 away from the push rod 3 means that when the push rod 3 extends towards the treatment head, it drives the transducer 4 and the transducer bracket 5 away from the handle housing 1. The transducer bracket 5 compresses the elastic element 7, causing the elastic element 7 to be in a state of compression deformation. When the push rod 3 retracts, the elastic element 7 uses its own elastic restoring force to drive the transducer bracket 5 closer to the handle housing 1, ensuring that the push rod 3 is connected to the transducer 4 and preventing it from becoming loose.

[0108] Specifically, port 51 is located at the upper end of the transducer assembly;

[0109] The through hole 52 is located between the mating port 51 and the transducer 4.

[0110] It should be noted that, since the handle housing 1 is designed for easy hand gripping, based on the spatial structure of the handle housing 1, the mating port 51 is located at the upper end of the transducer bracket 5, and the through hole 52 is located between the mating port 51 and the transducer 4, so as to ensure the miniaturization of the handle housing 1 structure.

[0111] Specifically, there are multiple through holes 52;

[0112] The number of guide posts 6 is the same as the number of through holes 52.

[0113] It should be noted that by setting the number of through holes 52 to multiple, and setting multiple support guide posts 6 corresponding to the number of through holes 52, the cooperation between the multiple support guide posts 6 and the multiple through holes 52 can further ensure that the transducer support 5 can reciprocate along the multiple support guide posts 6, and further improve the smoothness of the reciprocating movement of the transducer support 5.

[0114] Furthermore, the handheld assembly also includes: a first plug 81, a second plug 82, a first telescopic tube 83, and a second telescopic tube 84 disposed within the treatment head housing 8;

[0115] The first plug 81 is located at the second opening, and a third opening is provided for the push rod 3 to pass through;

[0116] The first telescopic tube 83 is sleeved on the push rod 3, and the first end of the first telescopic tube 83 is connected to the transducer bracket 5, and the second end is connected to the first plug 81.

[0117] The first end of the second telescopic tube 84 is disposed on the transducer bracket 5 and is symmetrically arranged with the first telescopic tube 83.

[0118] The second plug 82 is located at the second end of the second telescopic tube 84.

[0119] It should be noted that the treatment head housing 8 of this application is used to fill the liquid medium of ultrasound, and the first end of the treatment head housing 8 is provided with a second opening for the push rod 3 to pass through. In order to avoid leakage of the liquid medium, this application provides a first plug 81 at the second opening, and a third opening for the push rod 3 to pass through the first plug 81. The first telescopic tube 83 is sleeved on the push rod 3, and the first end of the first telescopic tube 83 is connected to the transducer bracket 5, and the second end is connected to the first plug 81. The first end of the second telescopic tube 84 is provided on the transducer bracket 5 and is symmetrically arranged with the first telescopic tube 83. The second plug 82 is provided at the second end of the second telescopic tube 84, thereby effectively preventing the liquid medium from leaking out from the second opening.

[0120] Preferably, a sealing ring 85 is provided on the outside of the first plug 81.

[0121] It should be noted that by fitting a sealing ring 85 over the outside of the first plug 81, the sealing performance between the first plug 81 and the second opening can be further improved.

[0122] Furthermore, the linear treatment head also includes: a bushing 9;

[0123] The bushing 9 is located in the through hole 52 and is fitted onto the bracket guide post 6.

[0124] It should be noted that by placing the bushing 9 in the through hole 52 and fitting it onto the bracket guide post 6, the resistance of the transducer bracket 5 reciprocating movement is reduced, thereby improving the smoothness of the transducer bracket 5 reciprocating movement along the bracket guide post 6, reducing the noise generated during reciprocating movement, extending the lifespan of the bracket guide post 6 and the through hole 52, and effectively improving the user experience.

[0125] This application also provides an embodiment, such as in the rake-shaped handle design, by setting the above-mentioned handheld component, when the push rod drives the transducer bracket to achieve linear movement, the elastic element can also generate elastic deformation when the push rod extends and drives the transducer bracket away from one end of the handle housing, that is, to perform elastic energy storage. Then, when the push rod retracts, the elastic element can provide elastic restoring force for the transducer bracket to prevent the transducer bracket from loosening and separating from the push rod.

[0126] Based on the handheld component provided in the above embodiments, this utility model also provides an ultrasonic therapy device, which includes: a handheld component;

[0127] The handheld assembly includes: a handle housing 1, a power assembly 2, a push rod 3, a transducer assembly, an elastic element 7, and a treatment head housing 8;

[0134] The elastic element 7 is disposed inside the treatment head housing 8, and the elastic element 7 can generate elastic deformation when the transducer assembly is away from the power assembly 2.
