[0047] The second end of the ultrasonic transducing element 130 forms a second electrode end with the bottom shell 110 and the top shell 120.

[0048] Specifically, the top (i.e. the first end) of the ultrasonic transducing element 130 is positive, the bottom (i.e. the second end) is negative, and the sidewall is not conductive, so that the sidewall of the ultrasonic transducing element 130 is not conductive with the bottom shell 110, and only the bottom of the ultrasonic transducing element 130 is conductive with the bottom shell 110.

[0049] In this embodiment, both the bottom shell 110 and the top shell 120 are made of conductive material, which not only provides structural support, but also enables them to participate in conduction as part of the circuit.

[0050] The bottom shell 110 is provided with a receiving groove 111 for mounting the ultrasonic transducing element 130, and the top shell 120 is provided with a receiving through hole 121 that is in communication with the receiving groove 111 of the bottom shell 110, forming a closed cavity to protect the internal elements.

[0051] The bottom shell 110 and the top shell 120 are fixedly connected by sealing, ensuring the sealing of the cavity and preventing the ultrasonic transducing element 130 inside from being affected by external environment such as moisture and dust.

[0053] With reference to Figures 1 to 3 The ultrasonic transducing unit further comprises a limiting fixing part 150, which is fixedly and sealingly nested in the receiving through hole 121, and the bottom end of the electrically connecting part 140 is arranged in the limiting fixing part 150.

[0054] The sealing of the ultrasonic transducing element 130 is realized by the sealing connection of the bottom shell 110 and the top shell 120 and the sealing treatment of the containing through hole 121 and the containing groove 111 by the limiting fixing part 150. The limiting and fixing of the ultrasonic transducing element 130 are realized by the containing groove 111 and the limiting fixing part 150. The indirect connection of the ultrasonic transducing element 130 and the external electrode connecting wire (i.e. the wire; the positive electrode connecting wire and the negative electrode connecting wire) or the positive and negative electrode ends of the power supply is realized by the first electrode end formed by the first end of the ultrasonic transducing element 130 and the electrically connecting part 140 and the second electrode end formed by the second end of the ultrasonic transducing element 130, the bottom shell 110 and the top shell 120. In general, the ultrasonic transducing unit 100 of the utility model can realize the sealing and fixing of the ultrasonic transducing element 130 and the indirect electrically connecting with the external electrode connecting wire, thereby avoiding the unstable connection of the ultrasonic transducing element 130 and the external electrode connecting wire, the poor contact and the problem of the poor sealing of the shell and the damp.

[0055] With reference to Figures 1 to 3 The electrically connecting part 140 comprises a first electrically connecting part 141 and a second electrically connecting part 142, the first electrically connecting part 141 is embeddedly connected with the second electrically connecting part 142 and arranged in the limiting fixing part 150.

[0056] The second electrically connecting part 142 has a first connecting part and a second connecting part which are not electrically connected with each other, the first end of the ultrasonic transducing element 130 forms a first electrode end through the first electrically connecting part 141 and the first connecting part of the second electrically connecting part 142, and the second end of the ultrasonic transducing element 130 forms a second electrode end through the bottom shell 110, the top shell 120 and the second connecting part of the second electrically connecting part 142.

[0057] In the embodiment, the embeddedly connected first electrically connecting part 141 and the second electrically connecting part 142 ensure the stability and reliability of the circuit connection. Meanwhile, the sealing nesting design of the limiting fixing part 150 also enhances the stability and sealing of the whole structure and prevents the interference of the external environment on the circuit connection. The isolation between the circuits is ensured through the first connecting part and the second connecting part which are not electrically connected with each other, and unnecessary current interference or short circuit is avoided.

[0058] With reference to Figures 1 to 3 The second electrically connecting part 142 comprises a positive connecting layer 1421, an insulating layer 1422 and a negative connecting layer 1423, the positive connecting layer 1421 is the first connecting part, and the negative connecting layer 1423 is the second connecting part.

[0060] The bottom end of the positive electrode connecting layer 1421 is electrically connected to the first electrical connecting member 141, and the top end thereof is electrically connected to the positive electrode connecting wire. The outer sidewall of the negative electrode connecting layer 1423 is electrically connected to the top shell 120, and the top end thereof is electrically connected to the negative electrode connecting wire.

[0061] In this embodiment, the insulating layer 1422 plays a role of electrical isolation, prevents short circuit between the positive electrode connecting layer 1421 and the negative electrode connecting layer 1423, and ensures that the current can only flow along the predetermined path. The insulating layer 1422 is usually made of non-conductive materials such as plastic, rubber or ceramic, and has high insulation strength and stability.

[0062] The negative electrode connecting wire, the negative electrode connecting layer 1423, the top shell 120, the bottom shell 110, the ultrasonic transducer element 130, the first electrical connecting member 141, the positive electrode connecting layer 1421, and the positive electrode connecting wire constitute a complete circuit loop.

[0063] In summary, the above-mentioned structures jointly constitute an efficient and stable electrical connection system.

[0064] In other embodiments, the positive electrode connecting layer 1421, the insulating layer 1422, and the negative electrode connecting layer 1423 are sequentially stacked in a stacking manner along the radial direction of the accommodating through hole 121.

[0065] Referring to Figures 1 to 3 , the first electrical connecting member 141 is an electrode spring needle. The first electrical connecting member 141 includes an elastic connecting end 1411 and a first extending end 1412. The bottom of the elastic connecting end 1411 abuts against the ultrasonic transducer element 130, and the first extending end 1412 is arranged at the top of the elastic connecting end 1411.

[0066] The bottom end of the positive electrode connecting layer 1421 is provided with a second extending end 1424. The bottom end of the second extending end 1424 is provided with an extending embedding groove 14241, and the first extending end 1412 is embedded and fixed in the extending embedding groove 14241.

[0067] In this embodiment, the elastic connecting end 1411 is designed to be elastic. When subjected to a certain pressure, the elastic connecting end 1411 can deform, thereby ensuring close contact with the ultrasonic transducer element 130 and improving the stability and reliability of the electrical connection.

[0068] The first electric connection piece 141 and the positive electrode connection layer 1421 are stably connected through the extension slot 14241 in the first extension end 1412 and the second extension end 1424, and the embedded fixing mode is simple and easy to implement and can effectively prevent poor contact caused by vibration or impact.

[0069] In summary, the ultrasonic transducing unit 100 has high reliability and good contact performance, and is easy to install and maintain.

[0070] With reference to Figures 1 to 3 The limiting fixing piece 150 comprises an insulating limiting layer 151 and a conductive limiting layer 152, and the conductive limiting layer 152 is arranged outside the insulating limiting layer 151,

[0071] The bottom of the conductive limiting layer 152 is sealingly connected in the accommodating through hole 121, and the top thereof abuts against the bottom of the negative electrode connection layer 1423, and the first electric connection piece 141 is embedded in the insulating limiting layer 151.

[0072] The second end of the ultrasonic transducing element 130 forms a second electrode end through the bottom shell 110, the top shell 120, the conductive limiting layer 152 and the negative electrode connection layer 1423.

[0073] In the embodiment, the insulating limiting layer 151 mainly plays an electrical isolation role, prevents current from flowing in an unnecessary path, i.e., prevents short circuit caused by the communication of the first electric connection piece 141 and the conductive limiting layer 152, and ensures the safety and stability of the circuit. The insulating limiting layer 151 is usually made of non-conductive materials, such as plastic, rubber or ceramic.

[0075] Specifically, the conductive limiting layer 152 realizes electrical connection with the negative electrode connection layer 1423, and the bottom thereof is connected with the accommodating through hole 121 through a threaded connection mode, and the connection mode is not only stable and reliable, but also facilitates installation and disassembly.

[0076] With reference to Figures 1 to 3 The insulating limiting layer 151 is provided with a first limiting hole 1511 and a second limiting hole 1512, the elastic connection end 1411 is embedded in the first limiting hole 1511, the second extension end 1424 is embedded in the second limiting hole 1512, and the diameter of the second limiting hole 1512 is smaller than that of the elastic connection end 1411.

[0077] In this embodiment, by embedding the elastic connection end 1411 and the second extension end 1424 in the first limiting hole 1511 and the second limiting hole 1512 respectively, the first insulating limiting layer 151 provides stable support and positioning for them; combined with the extension slot 14241 that the first extension end 1412 is embedded in the second extension end 1424, it reduces the risk of component loosening or displacement caused by vibration or impact, thereby improving the stability of the entire electrical connection system.

[0078] The insulating limiting layer 151 ensures the isolation and positioning between electrical components, while the conductive limiting layer 152 is responsible for guiding the current to the predetermined path. By precisely positioning the first electrical connection 141 and the second extension end 1424 of the positive connection layer 1421, the conductive limiting layer 152 can form good contact with them, thereby achieving reliable electrical connection.

[0079] The ultrasonic transduction unit 100 also includes a connection socket (not shown in the figure), one end of which is electrically connected to the top of the positive connection layer 1421, and the other end is electrically connected to the top of the negative connection layer 1423, and the connection socket is used for electrically connecting the positive and negative electrode connecting wires.

[0080] In this embodiment, the ultrasonic transduction unit 100 realizes the connection of the ultrasonic transduction element 130 and the positive and negative electrode connecting wires through plug-in, making the overall design of the ultrasonic transduction unit 100 more modular and standardized, facilitating production, installation and maintenance. The use of the connection socket improves the flexibility and scalability of the system, and users can choose different specifications and types of wires or power plugs for connection according to their needs. At the same time, the socket also plays a role in protecting the internal circuit (ultrasonic transduction element 130, first electrical connection 141, second electrical connection 142), preventing electrical failure and damage caused by external factors (such as moisture, dust, etc.).

The first sealing groove 1111 and the second sealing groove 122 are embeddedly connected and a first sealing ring 160 is arranged therebetween, and the accommodating groove 111 is sealingly connected with the first connecting groove 123.

[0082] In this embodiment, such embedded connection not only provides structural stability, but also provides a basis for sealing. When they are embedded, a relatively closed space is formed between them, which helps to prevent external impurities, moisture or gas from entering the interior of the device.

[0083] The first sealing ring 160 further enhances the airtightness. When the top shell 120 and the bottom shell 110 are fitted together, the sealing ring is compressed and fills the tiny gap between them, thus forming an effective sealing barrier. This barrier can prevent external environmental interference and ensure the normal operation of the internal components of the device. The first sealing ring 160 is usually made of materials with good elasticity and sealing performance, such as rubber, silicone, etc.

[0084] Specifically, the accommodating groove 111 is threadedly connected with the first connecting groove 123. The threaded connection not only provides strong connecting force, but also has a certain self-locking property, which can resist the influence of vibration and impact to a certain extent. This connection method ensures the stability and reliability of the device in complex working environments.

[0085] Referring to Figures 1 to 3 The accommodating groove 111 is provided with a containing boss 112 in the middle of the groove bottom, and the containing boss 112 is provided with a limiting groove 1121. The ultrasonic transduction element 130 is fixed radially in the limiting groove 1121.

[0088] In this embodiment, the top shell 120 is sealingly connected to the connecting through-hole 210, and the opening of the accommodating through-hole 121 is located in the closed cavity, which realizes the stable connection of the top shell 120 and the connecting shell 200. This connection method is simple and reliable, and can effectively resist vibration and impact.

[0089] Specifically, the top end side wall of the top shell 120 is provided with a threaded groove 1243 for threaded connection with the nut 400, and the top end of the top shell 120 penetrates the connection through hole 210 and is provided in the closed cavity and threaded connected with the nut 400; or the top end side wall of the top shell 120 is provided with a threaded groove 1243 for threaded connection with the connection through hole 210.
