Description

TECHNICAL FIELD

[0001] The utility model relates to ultrasonic technology field, specifically, relate to an ultrasonic transducer, further relate to the ultrasonic equipment of application this ultrasonic transducer. BACKGROUND

[0002] Ultrasonic transducer is the device that utilizes piezoelectric effect to change the mechanical vibration of ultrasonic wave into electric signal or produces mechanical vibration under electric field drive to emit ultrasonic wave. The existing ultrasonic transducer usually adopts split type ultrasonic transducer, and the flange of different materials (usually soft metal) is used to fix the transducer on the ultrasonic equipment. Since it is split type assembly mode, a part of the power of ultrasonic transducer is consumed on the flange, which leads to the increase of power loss and inconvenient installation.

[0003] Therefore, it is necessary to consider a more optimized ultrasonic transducer structure. SUMMARY

[0004] The first object of the utility model is to provide an ultrasonic transducer which has a damping function and can reduce power loss.

[0005] The second object of the utility model is to provide an ultrasonic equipment which has a damping function and can reduce power loss.

[0006] In order to achieve the above-mentioned first object, the ultrasonic transducer provided by the utility model comprises a transducer main body, a flange structure is arranged on the outer periphery of the transducer main body, and the transducer main body and the flange structure are integrally formed; the flange structure cooperates with the outer peripheral wall of the transducer main body to form a first damping groove around the outer peripheral wall, and the depth direction of the first damping groove is arranged in the same direction as the axial direction of the transducer main body.

[0007] According to the above-mentioned scheme, the ultrasonic transducer of the utility model has the flange structure arranged on the outer periphery of the transducer main body, and the transducer main body and the flange structure are integrally formed, which reduces the power loss caused by fixing the transducer main body through the split flange. At the same time, the transducer does not need to be assembled, and can be directly installed on the equipment, improving the installation efficiency. In addition, the flange structure cooperates with the outer peripheral wall of the transducer main body to form the first damping groove, which enables the ultrasonic transducer to have a damping function. At the same time, the heat dissipation area is increased, the heat dissipation effect is improved, and the power loss of the transducer is reduced.

[0008] In a further scheme, the flange structure is provided with a second damping groove, which is located outside the first damping groove in the radial direction of the transducer main body, and the depth direction of the second damping groove is arranged in the same direction as the axial direction of the transducer main body.

[0009] Therefore, by setting a second damping groove in the flange structure, the damping effect and heat dissipation effect can be further improved.

[0010] In a further embodiment, the openings of the first damping groove and the second damping groove are arranged in opposite directions along the axial direction of the transducer body.

[0011] Therefore, it can be seen that the openings of the first damping groove and the second damping groove are set in opposite directions, which can optimize the damping mechanism and improve the damping effect.

[0012] In a further embodiment, the bottom of the second damping groove is provided with multiple through holes, which are evenly arranged along the circumference of the flange structure at the bottom of the second damping groove.

[0013] Therefore, by setting multiple through holes at the bottom of the second damping groove, heat dissipation can be improved, and the damping effect can be further enhanced.

[0014] In a further design, threads are provided on the outer peripheral wall of the flange structure.

[0015] Therefore, it can be seen that by setting threads on the outer peripheral wall of the flange structure, the installation of ultrasonic transducers can be facilitated.

[0016] In a further embodiment, the transducer body includes a head and a wave-emitting section, which are connected axially along the transducer body, and the diameter of the head is larger than the diameter of the wave-emitting section.

[0017] It can be seen that the diameter of the head of the transducer body is larger than the diameter of the output section, which can make the ultrasonic waves more powerful and the power more stable. The principle is that the power is transmitted over a large area at the head and concentrated into a small area at the output section.

[0018] In a further design, a wrench-like disassembly mechanism is provided at the end of the wave-emitting section furthest from the head.

[0019] Therefore, the addition of a wrench-equipped disassembly and assembly structure allows operators to disassemble and assemble ultrasonic transducers more quickly.

[0020] In a further design, the diameter of the wave output section gradually decreases along the direction away from the head in the axial direction of the transducer body.

[0021] As can be seen, the diameter of the wave-emitting part is gradually reduced along the direction away from the head. As the diameter gradually decreases, the sound waves will converge towards the central axis during propagation, which can concentrate the sound wave energy more in a specific area and enhance the sound wave intensity in the target area.

[0022] To achieve the second objective mentioned above, the ultrasonic device provided by this utility model includes an ultrasonic transducer, which employs the aforementioned ultrasonic transducer. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0028] Example of an ultrasonic transducer:

[0029] like Figure 1 As shown, in this embodiment, the ultrasonic transducer includes a transducer body 1, and a flange structure 2 is provided on the outer periphery of the transducer body 1. The transducer body 1 and the flange structure 2 are integrally formed.

[0030] In this embodiment, the transducer body 1 includes a head 11 and a wave-emitting part 12, which are connected along the axial direction of the transducer body 1. The diameter of the head 11 is larger than the diameter of the wave-emitting part 12. The larger diameter of the head 11 compared to the wave-emitting part 12 allows for more powerful and stable ultrasonic wave transmission. This is because power is transmitted over a large area in the head 11, and then concentrated into a smaller area in the wave-emitting part 12. Preferably, the diameter of the wave-emitting part 12 gradually decreases along the axial direction away from the head 11. This gradual decrease in diameter allows the sound waves to converge towards the central axis, concentrating the sound energy within a specific area and enhancing the sound intensity in the target area.

[0031] In this embodiment, a wrench removal and assembly structure 121 is provided at the end of the wave-emitting part 12 away from the head 11. The wrench removal and assembly structure 121 is a structure that is configured to cooperate with a wrench. By providing the wrench removal and assembly structure 121, the operator can remove and assemble the ultrasonic transducer more quickly.

[0032] In this embodiment, see Figure 2 , Figure 3 and Figure 4The flange structure 2, in conjunction with the outer peripheral wall of the transducer body 1, forms a first damping groove 3 surrounding the outer peripheral wall of the transducer body 1. The depth direction of the first damping groove 3 is aligned with the axial direction of the transducer body 1. The flange structure 2 is provided with a second damping groove 21. In the radial direction of the transducer body 1, the second damping groove 21 is located outside the first damping groove 3, and its depth direction is aligned with the axial direction of the transducer body 1. In the axial direction of the transducer body 1, the openings of the first damping groove 3 and the second damping groove 21 are opposite in orientation. By providing the first damping groove 3 and the second damping groove 21 in the flange structure 2, the damping effect can be improved, and the heat dissipation area can be increased, thus improving heat dissipation. The opposite orientation of the openings of the first damping groove 3 and the second damping groove 21 makes the cross-section of the flange structure 2 square-wave shaped, optimizing the damping structure and contributing to improved damping performance.

[0033] In this embodiment, the bottom of the second damping groove 21 is provided with a plurality of through holes 22, which are evenly arranged along the circumference of the flange structure 2 at the bottom of the second damping groove 21. By providing a plurality of through holes 22 at the bottom of the second damping groove 21, heat dissipation can be improved, and the damping effect can be further improved.

[0034] In addition, threads 23 are provided on the outer peripheral wall of flange structure 2. By providing threads 23 on the outer peripheral wall of flange structure 2, the installation of ultrasonic transducers can be facilitated.

[0035] In this embodiment, when the ultrasonic transducer is installed on the ultrasonic equipment, it is screwed onto the corresponding structure of the ultrasonic equipment via threads 23. By turning a wrench on the disassembly / removal structure 121, the transducer body 1 rotates, thereby tightening the ultrasonic transducer onto the ultrasonic equipment. During operation, the first damping groove 3 and the second damping groove 21 buffer the vibration of the ultrasonic transducer, reducing the force exerted by the ultrasonic equipment on the ultrasonic transducer and minimizing power loss.

[0036] As described above, the ultrasonic transducer of this invention, by providing a flange structure 2 on the outer periphery of the transducer body 1 and integrally molding the transducer body 1 and the flange structure 2, reduces the power loss caused by fixing the transducer body 1 with a separate flange. Furthermore, it eliminates the need for transducer assembly, facilitating direct installation on equipment and improving installation efficiency. In addition, the flange structure 2, in conjunction with the outer peripheral wall of the transducer body 1, forms a first damping groove 3, enabling the ultrasonic transducer to have vibration damping capabilities. Simultaneously, it increases the heat dissipation area, improves heat dissipation, and reduces the power loss of the transducer.

[0038] In this embodiment, the ultrasonic device includes an ultrasonic transducer, and the ultrasonic transducer is the ultrasonic transducer described in the above embodiment.

[0039] Ultrasonic equipment can be devices that require ultrasonic transducers, such as ultrasonic welding machines, ultrasonic cutting machines, ultrasonic cleaning machines, ultrasonic testing instruments, or ultrasonic physiotherapy instruments.

Any non-substantial modifications made to the present utility model using this concept shall also fall within the protection scope of the present utility model.
