Technical Field

[0001] This utility model relates to the field of ultrasonic transducer technology, specifically to an ultrasonic transducer with a self-cleaning function. Background Technology

[0002] The function of an ultrasonic transducer is to convert input electrical power into mechanical power and then transmit it, while consuming very little power itself.

[0003] Electrode connectors are key components in ultrasonic transducers used for transmitting electrical signals. They are typically made of metals with good electrical conductivity, such as copper and aluminum. During long-term use, these metals may experience increased contact resistance due to oxidation, corrosion, or contact with dirt, which in turn affects the transmission efficiency of electrical signals and the normal operation of the ultrasonic transducer. To address this issue, we propose an ultrasonic transducer with a self-cleaning function. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an ultrasonic transducer with a self-cleaning function, thus solving the problems mentioned in the background.

The grinding surface of the grinding disc contacts the electrode plate connector. The end of the drive shaft is equipped with a built-in motor, and the output shaft of the built-in motor is fixedly connected to the drive shaft. The sleeve assembly includes a sleeve, a support column is fixedly installed on the side of the sleeve, the upper end of the support column is fixedly connected to the U-shaped seat, a positioning column is fixedly installed on the inner side of the sleeve, and a secondary threaded hole is also opened on the sleeve. The lower end face of the device body is provided with a positioning groove and a main threaded hole. The sleeve is threadedly connected to a fastening bolt through the secondary threaded hole, and the fastening bolt can also be screwed into the main threaded hole.

[0006] By adopting the above technical solution, the electrode plate connector is placed inside the U-shaped seat, and the upper and lower surfaces of the electrode plate connector are polished by the polishing disc to clean the surface impurities and ensure the conductivity of the electrode plate. Furthermore, the establishment of two sets of driven gears and drive gears allows the two polishing discs to be driven to rotate and polish simultaneously by a single built-in motor as the power output source. The sleeve ensures that the U-shaped seat is stably fixed on the device body, ensuring that the internal polishing discs have stable working conditions to complete the polishing and cleaning process.

[0007] Preferably, the built-in motor is located in the cavity inside the support column, and the output shaft of the built-in motor passes through the support column and is fixedly connected to the drive shaft.

[0008] By adopting the above technical solution, the drive shaft can rotate on its own after the built-in motor is started, thus serving as a power output source to drive the entire structure to operate. The built-in motor can increase its rotation speed to meet the actual needs of grinding and cleaning impurities.

[0009] Preferably, the U-shaped seat is provided with two grinding discs, and the grinding surfaces of both grinding discs can contact the connector surface of the electrode sheet.

[0010] By adopting the above technical solution, the grinding disc can directly contact the impurities on the connector surface of the electrode sheet after it rotates, and then the rough surface of the grinding disc is used to remove the impurities.

[0011] Preferably, both the driving gear and the driven gear are located in the internal cavity of the U-shaped seat. There are two driving gears in total, and the number of driven gears is the same as the number of driving gears.

[0012] By adopting the above technical solution, the transmission effect of the overall structure can be improved, so as to achieve the effect of simultaneously driving multiple grinding discs to rotate synchronously for grinding. The cavity inside the U-shaped seat can accommodate the driving gear and the driven gear, so that the driving gear and the driven gear have enough space to rotate, and prevent the structure inside the U-shaped seat from interfering with the rotation of the driving gear and the driven gear.

[0013] Preferably, the positioning post can be inserted into the positioning groove, and there are two positioning posts in total.

[0015] Preferably, the positioning groove has an arc-shaped structure design, and both ends of the positioning groove are closed designs.

[0016] By adopting the above technical solution, the sleeve can achieve directional rotation by utilizing the cooperation between the positioning pin and the positioning groove, thereby driving the U-shaped seat to rotate together, so that the electrode plate connector is placed at the notch of the U-shaped seat, and the grinding disc of the U-shaped seat comes into contact with the electrode plate connector.

[0017] Preferably, the bottom surface of the sleeve has an opening for accommodating the end cap of the fastening bolt.

[0018] By adopting the above technical solution, the flatness of the bottom surface of the sleeve after it is locked into the body can be guaranteed, thus facilitating the stable placement of the overall structure.

[0019] Preferably, after the sleeve is spliced ​​onto the body, the axis of the secondary threaded hole coincides with the axis of the main threaded hole.

[0020] By adopting the above technical solution, the smoothness of tightening the fastening bolts is ensured, allowing users to use the fastening bolts to lock the sleeve onto the device body, further ensuring the rationality of the overall structural design and meeting actual usage needs.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. This self-cleaning ultrasonic transducer, by setting up a cleaning mechanism, allows the electrode plate connectors to be placed inside the U-shaped seat. Therefore, after starting the built-in motor, the two grinding discs can be rotated sequentially through the drive shaft, drive gear, driven gear, and driven shaft. The rotating grinding discs can remove dirt and oxides from the surface of the electrode plate connectors, maintaining their good conductivity and helping to ensure that the electrical signal can be transmitted efficiently and stably, thereby maintaining the normal operation of the ultrasonic transducer.

[0023] 2. This self-cleaning ultrasonic transducer uses a sleeve assembly to quickly attach the cleaning mechanism to the body, allowing for flexible adjustment of the connection between the cleaning mechanism and the ultrasonic transducer. This enhances the practicality of the overall device, and the overall structure is simple and easy to operate. Attached Figure Description

[0030] 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.

[0031] Please see Figure 1-5 An ultrasonic transducer with self-cleaning function includes: a body 1, on which electrode 2 and piezoelectric ceramic 3 are respectively disposed, the electrode 2 and piezoelectric ceramic 3 are in contact, and a cleaning mechanism 4 and a sleeve assembly 5 are also disposed on the body 1.

[0032] The cleaning mechanism 4 includes a U-shaped base 41, inside which a driven shaft 43 and a drive shaft 46 are rotatably arranged. A polishing disc 42 and a driven gear 44 are fixedly mounted at both ends of the driven shaft 43, respectively. A drive gear 45 is fixedly mounted on the outer surface of the drive shaft 46, meshing with the driven gear 44. The polishing surface of the polishing disc 42 contacts the connector of the electrode plate 2. A built-in motor 47 is located at the end of the drive shaft 46, and the output shaft of the built-in motor 47 is fixedly connected to the drive shaft 46. Both the wheel 45 and the driven gear 44 are located in the internal cavity of the U-shaped seat 41. There are two drive gears 45, and the number of driven gears 44 is the same as the number of drive gears 45. The U-shaped seat 41 is provided with two grinding discs 42. The grinding surfaces of the two grinding discs 42 can contact the joint surface of the electrode plate 2, thereby achieving the purpose of grinding and cleaning the joint of the electrode plate 2. The built-in motor 47 is located in the internal cavity of the support column 52, and the output shaft of the built-in motor 47 passes through the support column 52 and is fixedly connected to the drive shaft 46.

[0033] The sleeve assembly 5 includes a sleeve 51, a support column 52 fixedly mounted on the side of the sleeve 51, the upper end of the support column 52 fixedly connected to the U-shaped seat 41, a positioning column 53 fixedly mounted on the inner side of the sleeve 51, and a secondary threaded hole 56 opened on the sleeve 51. A positioning groove 55 and a main threaded hole 57 are opened on the lower end face of the body 1. The sleeve 51 is threadedly connected to a fastening bolt 54 through the secondary threaded hole 56. The fastening bolt 54 can also be screwed into the main threaded hole 57. The sleeve 51 is spliced. After being mounted on the device body 1, the axis of the auxiliary threaded hole 56 coincides with the axis of the main threaded hole 57, and the sleeve 51 can be fastened to the device body 1 by the fastening bolt 54, thereby facilitating the stable operation of the cleaning mechanism 4. The bottom surface of the sleeve 51 is provided with an open mouth for accommodating the end cap of the fastening bolt 54. The positioning groove 55 is designed with an arc shape, and both ends of the positioning groove 55 are closed. The positioning pin 53 can be inserted into the positioning groove 55. There are two positioning pins 53 in total.

[0034] Working principle: The positioning pin 53 on the inner side of the sleeve 51 cooperates with the positioning groove 55 at the lower end of the body 1 to splice the sleeve 51 to the bottom of the body 1. At the same time, the positioning groove 55 can limit the rotation range of the sleeve 51, so that the connector of the electrode plate 2 is engaged with the U-shaped seat 41 on the support pin 52 until the connector of the electrode plate 2 is placed between the two grinding discs 42, so that both the upper and lower sides of the connector of the electrode plate 2 are in contact with the grinding discs 42. Tighten the fastening bolt 54 to secure the connector. 54 is thus screwed into the body 1 through the sleeve 51 to fix the sleeve 51 to the body 1. Then the built-in motor 47 inside the support column 52 is started. The output shaft of the built-in motor 47 drives the drive shaft 46 to rotate. The drive gear 45 on the drive shaft 46 meshes with the driven gear 44 at the end of the driven shaft 43. After the drive shaft 46 rotates, the driven gear 44, the driven shaft 43 and the polishing disc 42 rotate synchronously to polish away the dirt and oxides on the surface of the electrode plate 2 connector.
