Description

Technical Field

[0001] This utility model relates to the field of ultrasound, and in particular to a transducer assembly. Background Technology

[0002] An ultrasonic transducer is a device that converts electrical energy into acoustic energy (i.e., high-frequency mechanical vibration energy). Ultrasonic cleaning achieves a good cleaning effect by generating ultrasonic vibrations through the transducer, which create cavitation effects in water, producing instantaneous high-pressure bubbles that impact the object being cleaned.

[0003] Traditional ultrasonic transducers can be broadly classified into two categories based on their usage and installation characteristics: fixed ultrasonic transducers and portable ultrasonic transducers.

[0004] Fixed ultrasonic transducers are typically permanently installed or fixed in one location for ultrasonic treatment of objects that are stationary or continuously passing through that location.

[0005] Portable ultrasonic transducers offer high flexibility, allowing them to be moved to different locations or work areas as needed. These transducers are typically combined with handheld devices, robotic arms, or other mobile platforms to enable ultrasonic treatment of complex-shaped objects or hard-to-reach areas. Portable ultrasonic transducers have wide applications in cleaning, descaling, surface treatment, and medical applications.

[0006] However, portable ultrasonic transducers consist of a transducer body and a solid ultrasonic rod connected to the transducer body. The solid ultrasonic rod is a variable cross-sectional area solid rod, and its local circumferential (radial) vibration is achieved through the angle of the variable cross-section, thereby realizing the output of multi-dimensional ultrasonic energy in both the axial and circumferential directions at the end of the solid ultrasonic rod. Because the solid ultrasonic rod is a variable cross-sectional area solid rod, it has a large mass and high vibration inertia. Therefore, traditional portable ultrasonic transducers are generally suitable for low-frequency applications. Portable ultrasonic transducers suffer from problems such as large mass, high vibration inertia, complex structure, and high cost. Utility Model Content

[0007] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a transducer assembly to solve the technical problems existing in the prior art.

[0008] To achieve the above and other related objectives, this utility model provides a transducer assembly, which includes at least a transducer body and an ultrasonic rod; the transducer body is electrically connected to an ultrasonic generator, and the transducer body includes at least one piezoelectric feature component; the piezoelectric feature component can directly or indirectly transmit the kinetic energy of mechanical vibration to the ultrasonic rod;

[0009] The ultrasonic rod comprises at least one rod structure. The ultrasonic rod is typically made of materials with high mechanical strength and good ultrasonic wave conduction properties, such as ceramics, quartz, or titanium alloys. These materials can effectively convert electrical energy into high-frequency mechanical vibration energy and ensure stable propagation of ultrasonic waves within the rod.

[0010] The structural design of the rod directly improves the transmission efficiency and effectiveness of ultrasound. At least one section of the rod structure has a cavity feature. This cavity feature enhances the circumferential ultrasound effect.

[0011] Furthermore, the voltage range of the ultrasonic generator output is 100V-1800V; the amplitude of the mechanical vibration is linearly related to the voltage output of the ultrasonic generator.

[0012] Furthermore, the ratio of the length of the cavity feature in the ultrasonic rod to the length of the ultrasonic rod is L, and 0 < L ≤ 0.9.

[0013] Furthermore, the wall thickness of the cavity feature in the ultrasonic rod is T, and 0.2 mm < T < 15 mm.

[0014] Furthermore, the frequency range of the transducer assembly is 15kHz to 200kHz.

[0015] Furthermore, the cavity feature in the ultrasonic rod has a closed outer contour, and its cross-section is a closed shape.

[0016] Furthermore, the closed shape can be any one of a circle, an ellipse, or a polygon.

[0017] Furthermore, at least a portion of the cavity features in the ultrasonic rod are non-variable cross-section cavities.

[0018] Furthermore, the piezoelectric feature is directly connected to the ultrasonic rod.

[0019] Furthermore, the piezoelectric feature component is connected to the ultrasonic rod via a mass matching block or an amplitude transformer.

[0020] As described above, the transducer assembly of this utility model has the following beneficial effects:

[0021] The ultrasonic rod comprises at least one rod structure. The piezoelectric feature can directly or indirectly transmit the kinetic energy of mechanical vibration to the ultrasonic rod; the kinetic energy is transmitted through the rod structure to achieve ultrasonic processing. Since at least one section of the rod structure has a cavity feature, the circumferential area covered by the kinetic energy can be expanded, thereby improving the ultrasonic effect. Compared with other rod transducers, less energy is required to achieve the same ultrasonic effect; and because the ultrasonic rod has a cavity, it is also lighter in weight.

[0031] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0032] Please see Figures 1 to 5 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0033] like Figure 1As shown, this utility model provides a transducer assembly, including at least a transducer body and an ultrasonic rod 2. The transducer body is electrically connected to an ultrasonic generator, and the transducer body includes at least one or more piezoelectric feature components 1. The voltage that the piezoelectric feature component 1 can withstand directly affects the amplitude of the ultrasound. The number of piezoelectric feature components 1 can be increased or decreased as needed. The ultrasonic rod 2 has a proximal end and a transmitting end opposite to the proximal end. The proximal end is closer to the piezoelectric feature component 1 than the transmitting end. The piezoelectric feature component 1 can directly or indirectly transmit the kinetic energy of mechanical vibration to the ultrasonic rod 2.

[0034] When the transducer body includes only one piezoelectric feature component 1, the first end of the piezoelectric feature component 1 is electrically connected to the ultrasonic generator via a cable, and the second end of the piezoelectric feature component 1 is directly connected to the proximal end of the ultrasonic rod 2. (See...) Figure 1 .

[0035] Alternatively, the piezoelectric feature component 1 may have a mass matching block at its head end, and the tail end of the piezoelectric feature component 1 may be directly connected to the proximal end of the ultrasonic rod 2; or, not only may the piezoelectric feature component 1 have a mass matching block at its head end, but the tail end of the piezoelectric feature component 1 may also have a mass matching block, and the head end of the piezoelectric feature component 1 may be connected to the proximal end of the ultrasonic rod 2 through the corresponding mass matching block; of course, a membrane structure or an amplitude transformer may also be designed at the tail end of the piezoelectric feature component 1; in another embodiment, refer to Figure 4 The first end of the piezoelectric feature component 1 is connected to the proximal end of the ultrasonic rod 2 via a membrane structure, or the first end of the piezoelectric feature component 1 is connected to the proximal end of the ultrasonic rod 2 via an amplitude transformer. Specifically, they are directly bonded together with glue, or connected together by mechanical connection methods such as threaded connection or snap-fit.

[0036] The ultrasonic rod 2 comprises at least one rod structure. The ultrasonic rod 2 is typically made of materials with high mechanical strength and good ultrasonic wave conduction properties, such as ceramics, quartz, or titanium alloys. These materials can effectively convert electrical energy into high-frequency mechanical vibration energy and ensure stable propagation of ultrasonic waves within the rod.

[0037] refer to Figure 1 The design of the rod structure directly improves the transmission efficiency and effect of ultrasound. At least one section of the rod structure has a cavity feature 21. Ultrasound propagates outwards from the surface of the cavity feature 21 and decreases in intensity, expanding the circumferential area covered by the ultrasound and thus improving the ultrasound effect. Compared with other rod transducers, it requires less input energy to achieve the same ultrasound effect.

[0038] The ultrasonic generator of this invention outputs a voltage range of 100V–1800V; the amplitude of the mechanical vibration is linearly related to the output voltage of the ultrasonic generator; that is, the higher the voltage, the larger the amplitude. The output amplitude (e.g., displacement, sound wave intensity, etc.) of this transducer assembly changes proportionally with the input voltage. Specifically, the amplitude A can be expressed as a linear function of the voltage V: A = k * V + b

[0039] in:

[0040] k is the proportionality coefficient, which represents the amplitude's responsiveness to voltage.

[0041] b is the amplitude offset, typically the amplitude value when the voltage is zero (if the system has zero amplitude when the voltage is zero, then b may be zero).

[0042] To ensure optimal ultrasonic coverage of this transducer assembly, the length ratio of the cavity feature 21 in the ultrasonic rod 2 to the length of the ultrasonic rod 2 is designed to be L, where 0 < L ≤ 0.9. Furthermore, the wall thickness of the cavity feature 21 in the ultrasonic rod 2 is T, where 0.2 mm < T < 15 mm.

[0043] refer to Figure 1 and Figure 2 The cavity feature 21 in the ultrasonic rod 2 of this invention has a closed outer contour, and its cross-section is a closed shape. The closed shape can be circular or elliptical; see reference. Figure 3 In other embodiments, the closed shape can also be designed as a polygon.

[0044] The cavity feature 21 in the ultrasonic rod 2 is a non-variable cross-section cavity, or a portion of the cavity feature 21 in the ultrasonic rod 2 is a non-variable cross-section cavity and a portion is a variable cross-section cavity 22, see Figure 5 .

[0045] Preferably, regardless of whether the cavity feature 21 in the ultrasonic rod 2 is a non-variable cross-section cavity or a variable cross-section cavity, the center of the cavity feature 21 in the length direction of the ultrasonic rod 2 coincides with the center of all cross-sections.

[0046] Preferably, both ends of the cavity feature 21 are closed, or at least one end of the cavity feature 21 is closed.

[0047] The frequency range of the transducer assembly is 15kHz to 200kHz.

[0048] In summary, the ultrasonic rod 2 of this invention comprises at least one rod structure. The piezoelectric feature 1 can directly or indirectly transmit the kinetic energy of mechanical vibration to the ultrasonic rod 2; the kinetic energy is transmitted through the rod structure to achieve ultrasonic processing. Since at least one section of the rod structure has a cavity feature 21, the circumferential area covered by the kinetic energy can be expanded, thereby improving the ultrasonic effect. Compared with other rod transducers, less energy is required for the same ultrasonic effect; and because the ultrasonic rod 2 has a cavity, its weight is also lighter. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0049] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
