Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ultrasonic technology and relates to an ultrasonic device. Background Technology
[0002] Ultrasonic equipment refers to equipment that uses ultrasonic waves to clean workpieces or to pulverize, disperse, homogenize, and emulsify materials. Specifically, ultrasonic equipment includes, but is not limited to, ultrasonic cleaning equipment and ultrasonic pulverizing / dispersing / homogenizing / emulsifying equipment.
[0003] These ultrasonic devices typically consist of a container and an ultrasonic generator. The container has an opening at the top and is used to hold the workpiece to be cleaned or the material to be pulverized / dispersed / homogenized / emulsified. The transducer of the ultrasonic generator is inserted into the liquid inside the container through this opening. When the device is working, the ultrasonic waves generate intense cavitation in the liquid, effectively removing dirt, oil stains, and particles from the surface and crevices of objects; or they generate high shear forces that break droplets / particles into very small pieces, achieving uniform mixing, emulsification, or dispersion.
[0004] In existing designs, ultrasonic devices are usually built-in, which means that the transducer part of the ultrasonic device occupies part of the space inside the container, sacrificing the effective working volume of the container and hindering possible loading and unloading operations. Therefore, there is room for improvement. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing an ultrasonic device.
[0006] The objective of this utility model can be achieved through the following technical solution: An ultrasonic device, comprising:
[0007] A container having an opening at the top and a base plate at the bottom capable of transmitting mechanical vibrations;
[0008] An ultrasonic module includes multiple ultrasonic transducers, each of which is tightly attached to the outer wall of the base plate. Each ultrasonic transducer is configured to transmit ultrasonic waves from outside the container into the container through the base plate.
[0009] Preferably, the container and the base plate are integrally formed metal parts.
[0010] Preferably, each of the ultrasonic transducers is evenly distributed across the entire base plate.
[0011] Preferably, the container is configured as a cylindrical can structure, and the outer wall of the container has a circular or elliptical outline.
[0012] Preferably, it also includes a heat dissipation element, which is in close contact with the outer wall of the container.
[0013] Preferably, the heat dissipation element is a liquid cooling pipe, which is spirally wound around the outer wall of the container, and the wall of the liquid cooling pipe is in close contact with the outer wall of the container.
[0014] Preferably, the device also includes a drive element and a stirring shaft, the stirring shaft being connected to the drive element and the drive element being capable of driving the stirring shaft to rotate, the stirring shaft extending into the container through the opening, and the portion of the stirring shaft extending into the container being provided with stirring blades.
[0015] Preferably, the driving element is a motor.
[0016] Preferably, the container also includes a lid, which is disposed on top of the container and seals the opening, and the drive element is mounted on the lid.
[0017] Preferably, it also includes an air pump and an air tube, one end of which is connected to the air pump and the other end of which extends into the container through the opening.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] 1. The ultrasonic transducer is located outside the container, forming an external structure. The ultrasonic transducer can indirectly transmit mechanical vibration (ultrasound) through the base plate, thereby realizing functions such as cleaning / crushing / dispersing / homogenizing / emulsifying. Furthermore, the ultrasonic transducer does not occupy the internal space of the container, ensuring the effective working volume of the container. The reserved space can be used to install a stirring device without hindering possible loading and unloading operations, thus improving the flexibility of using the ultrasonic equipment.
[0020] 2. Low-temperature coolant flows in the liquid cooling pipe. Since the liquid cooling pipe is in contact with the outer wall of the container, the coolant in the liquid cooling pipe exchanges heat with the liquid in the container, thereby effectively controlling the temperature of the liquid in the container and preventing the temperature rise caused by the continuous action of ultrasound from having an adverse effect on the material.
[0021] 3. Since the ultrasonic generator no longer occupies the container's opening and internal space, the freed-up space can be used to install a stirring shaft. The stirring shaft agitates the liquid within the container, allowing the equipment to perform ultrasonic treatment while simultaneously stirring, effectively eliminating dead zones in the ultrasonic process and resulting in more uniform pulverization, dispersion, homogenization, and emulsification.

[0027] In the diagram, 100 is the container; 110 is the opening; 120 is the base plate; 130 is the lid; 200 is the ultrasonic transducer; 300 is the liquid cooling pipe; 400 is the driving element; 500 is the stirring shaft; and 510 is the stirring blade. Detailed Implementation
[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0029] like Figures 1 to 5 As shown, an ultrasonic device includes:
[0030] The container 100 has an opening 110 at the top and a base plate 120 at the bottom that can transmit mechanical vibrations (ultrasonic energy).
[0031] The ultrasonic module includes multiple ultrasonic transducers 200, each of which is tightly attached to the outer wall of the base plate 120. Each ultrasonic transducer 200 is configured to transmit ultrasonic waves from outside the container 100 to inside the container 100 through the base plate 120.
[0032] The core of this equipment lies in the design of the ultrasonic transducer 200 on the bottom plate 120 of the container 100, thus forming an external structure (i.e., the transducer is located outside the container 100). Ultrasonic energy is indirectly transmitted from outside the container 100 to the liquid inside the container 100 through the bottom plate 120, achieving functions such as cleaning, pulverizing, dispersing, homogenizing, or emulsifying. The bottom plate 120 at the bottom of the container 100 has excellent mechanical vibration transmission performance. The ultrasonic transducer 200 is typically a transducer made of piezoelectric ceramic material. All ultrasonic transducers 200 are tightly fitted to the outer wall of the bottom plate 120, so the ultrasonic transducers 200 do not occupy the effective working space inside the container 100 and do not come into contact with the cleaning fluid or materials inside the container 100.
[0033] When the ultrasonic generator drives the ultrasonic transducer 200 to operate, the ultrasonic transducer 200 generates high-frequency mechanical vibrations based on the piezoelectric effect. Since the ultrasonic transducer 200 is tightly fitted to the base plate 120 and the two remain fixed, the base plate 120 and / or the entire container 100 can generate high-frequency mechanical vibrations together. This high-frequency mechanical vibration can act on the liquid inside the container 100, creating a cavitation effect within the liquid. Overall, this device can also be viewed as an ultrasonic system where the bottom of the container 100 mechanically vibrates, thereby driving the base plate 120 and / or the entire container 100 to vibrate together.
[0034] It should be noted that when using this equipment as an ultrasonic cleaning device, the container 100 needs to be pre-filled with cleaning fluid (e.g., water). The workpiece to be cleaned is then placed inside the container 100 for cleaning, and can be removed directly after cleaning. When using this equipment as an ultrasonic pulverizer / dispersion / homogenizer / emulsifier, the particulate material and solution are injected together into the container 100 for pulverization / dispersion / homogenization / emulsification.
[0035] The ultrasonic transducer 200 is installed outside the container 100, preventing it from entering the container and avoiding problems such as contamination and corrosion. This makes it suitable for applications requiring high cleanliness, such as food, pharmaceuticals, and biological products. Furthermore, it does not occupy internal space within the container 100, facilitating the placement of other equipment (such as stirring devices, pipelines, and sensors) and making automated loading and unloading operations easier. Additionally, the external location of the ultrasonic transducer 200 facilitates maintenance, replacement, or upgrades.
[0036] Preferably, the container 100 and the bottom plate 120 are integrally formed metal parts. Metal parts can better transmit mechanical vibrations and withstand stress fatigue caused by long-term high-frequency vibrations.
[0037] Preferably, each ultrasonic transducer 200 is evenly distributed across the entire base plate 120. Cavitation effect is one of the core mechanisms of ultrasonic action, and its intensity and distribution are directly affected by the vibration source. The evenly arranged ultrasonic transducers 200 can uniformly transmit ultrasonic energy to the liquid in the container 100, thereby forming a more uniform distribution of cavitation bubbles in the liquid and enhancing the overall processing efficiency.
[0038] Based on the above embodiments, the container 100 is configured as a round can structure, and the outline of the outer wall of the container 100 is circular or elliptical.
[0039] Example 1:
[0040] like Figures 1 to 5 As shown, based on the above embodiments, a heat dissipation element is also included, which is in close contact with the outer wall of the container 100.
[0041] In ultrasonic equipment, as the ultrasonic transducer 200 continues to operate, the temperature of the liquid inside container 100 gradually increases. If the equipment is performing pulverization / dispersion / homogenization / emulsification operations, some materials are sensitive to temperature. If the liquid temperature inside container 100 becomes too high, it may damage the material's structure (e.g., protein denaturation, inactivation of active ingredients, deterioration of material properties, runaway reaction, or generation of byproducts). Therefore, heat dissipation elements are installed on the outer wall of container 100 to remove heat from inside container 100, thereby cooling the liquid inside.
[0042] Based on Embodiment 1, the heat dissipation element is a liquid cooling pipe 300, which is spirally wound around the outer wall of the container 100, with the pipe wall tightly fitted to the outer wall of the container 100. Low-temperature coolant flows within the liquid cooling pipe 300. Because the liquid cooling pipe 300 is in contact with the outer wall of the container 100, heat exchange occurs between the coolant in the liquid cooling pipe 300 and the liquid inside the container 100, thereby effectively controlling the temperature of the liquid inside the container 100 and preventing adverse effects on the material caused by the continuous action of ultrasound.
[0043] It should be further explained that, because the container 100 adopts a cylindrical tank structure design, its outer wall surface has good roundness and continuity. Therefore, the liquid cooling pipe 300 can be easily spirally wound around the outer wall surface of the container 100 to form a spiral liquid cooling structure, ensuring full contact between the liquid cooling pipe 300 and the outer wall surface of the container 100. This layout not only increases the thermal contact area between the liquid cooling pipe 300 and the container 100, but also makes the temperature distribution of the entire container 100 more uniform in the circumferential and axial directions, thereby significantly improving cooling efficiency.
[0044] Example 2:
[0045] like Figures 3 to 5 As shown, based on the above embodiment, it also includes a drive element 400 and a stirring shaft 500. The stirring shaft 500 is connected to the drive element 400, and the drive element 400 can drive the stirring shaft 500 to rotate. The stirring shaft 500 extends into the container 100 through the opening 110, and the part of the stirring shaft 500 extending into the container 100 is provided with stirring blades 510.
[0046] Since the ultrasonic generator no longer occupies the opening 110 and internal space of the container 100, the freed-up space can be used to install the stirring shaft 500. By stirring the liquid in the container 100 with the stirring shaft 500, the equipment can perform stirring function while performing ultrasonic treatment, effectively eliminating dead zones in ultrasonic treatment, thereby making the crushing, dispersing, homogenizing and emulsifying effects more uniform.
[0047] In Example 2, while the container 100 is subjected to ultrasonic treatment, the drive element 400 drives the stirring shaft 500 to rotate, and the stirring blades 510 agitate the liquid, thereby stirring the liquid in the container 100. Through the synergistic effect of stirring and ultrasound, the effect and efficiency of processes such as pulverization, dispersion, homogenization, and emulsification are significantly improved.
[0048] Preferably, the drive element 400 is configured as a motor.
[0049] Preferably, it also includes a lid 130, which is disposed on top of the container 100 and seals the opening 110, and the drive element 400 is mounted on the lid 130.
[0050] The cover 130 effectively prevents liquid spillage, dust ingress, or harmful gas escape during processing. Furthermore, the drive element 400 is integrated into the cover 130, forming a detachable mixing module. Removing the cover 130 allows the entire mixing system to be removed. Additionally, using the cover 130 as a support platform for the drive element 400 saves on external supports, making the overall structure more compact.
[0051] Example 3:
[0052] It also includes an air pump and an air tube, one end of which is connected to the air pump and the other end of which extends into the container 100 through an opening 110.
[0053] In Example 3, the liquid in container 100 is stirred by injecting air through an air tube. Example 3 and Example 2 provide two different stirring methods. Compared with Example 2, Example 3 does not require a motor and stirring shaft 500, and is structurally simpler.
[0054] In this example, the container 100 has an opening 110 at the top and a base plate 120 at the bottom. Multiple ultrasonic transducers 200 are tightly attached to the outer wall of the base plate 120 (outside the container 100). After receiving the working signal from the ultrasonic generator, they transmit high-frequency vibrations to the liquid inside the container 100 through the base plate 120. A liquid cooling pipe 300 is spirally wound around the outer wall of the container 100 and is in contact with the outer wall of the container 100 for cooling. A motor can drive the stirring shaft 500 inside the container 100 to rotate, thereby stirring the liquid inside the container 100.
[0055] In actual operation, the ultrasonic generator drives the ultrasonic transducer 200 to work. The transducer generates high-frequency mechanical vibration based on the piezoelectric effect. The high-frequency vibration energy (ultrasonic waves) is transferred to the liquid inside the container 100 through the base plate 120 and / or the entire container 100. The ultrasonic waves generate a cavitation effect in the liquid. The coolant continuously flows in the spiral liquid cooling pipe 300. The heat generated during the operation of the container 100 is conducted to the liquid cooling pipe 300 through the container 100 wall and carried away by the flowing coolant, achieving effective cooling of the liquid inside the container 100 and controlling the temperature rise. At the same time, the motor drives the stirring shaft 500 to rotate, which in turn drives the stirring blades 510 immersed in the liquid to rotate, stirring the liquid. The stirring action promotes material movement and liquid circulation.
[0056] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0057] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0058] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0059] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
