Description

Technical Field

[0001] This utility model relates to the field of ultrasonic cleaning machine technology, and in particular to a low-noise ultrasonic cleaning machine. Background Technology

[0002] Ultrasonic cleaning machines utilize the cavitation, acceleration, and direct flow effects of ultrasonic waves in liquids to directly and indirectly act on liquids and contaminants, thereby dispersing, emulsifying, and peeling off the contaminant layer to achieve the purpose of cleaning. They are widely used in the cleaning of various items such as electronic components, mechanical parts, medical devices, and optical lenses.

[0003] The above-mentioned and existing technologies have the following drawbacks: When the ultrasonic cleaner is working, the vibration generated by the ultrasonic cleaner will be transmitted to the machine frame, causing the machine to resonate. At the same time, the ultrasonic waves will also generate a certain amount of noise when they propagate in the liquid. The superposition of these noises will form strong noise pollution, which will affect the hearing of the operator, especially in confined spaces or long-term operation scenarios.

[0004] Therefore, a low-noise ultrasonic cleaning machine is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing ultrasonic cleaning machines, which are characterized by high noise levels, noise pollution, and negative impact on the working environment of operators. This invention proposes a low-noise ultrasonic cleaning machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a low-noise ultrasonic cleaner, comprising an ultrasonic cleaner body, four base frames fixedly mounted on the surface of the ultrasonic cleaner body, a noise-reducing shell fixedly mounted on the surface of the ultrasonic cleaner body, a sound-insulating cavity formed between the surface of the noise-reducing shell and the ultrasonic cleaner body, the inner wall of the sound-insulating cavity being filled with sound-absorbing cotton, a cover plate rotatably connected to the surface of the noise-reducing shell, a plurality of vent holes evenly opened on the surface of the cover plate, sound-absorbing cotton plugs provided on the inner wall of the vent holes, and a handle fixedly mounted on the surface of the cover plate.

[0007] The effects achieved by the above components are as follows: by setting up noise-reducing shells and sound-insulating chambers, a multi-layered noise-blocking structure is constructed, which can effectively block the propagation path of noise and reduce noise pollution caused by airborne and structural sound transmission at the source. Combined with the sound-absorbing design of ventilation holes and sound-absorbing cotton plugs on the cover, a multi-directional noise reduction protection is formed, which further improves the noise reduction effect and provides operators with a quieter and more comfortable working environment in confined spaces or long-term work scenarios, reducing the impact of noise on the operator's hearing.

[0008] Preferably, the surface of the noise-reducing housing is provided with an electrostatic powder coating layer.

[0009] The effects achieved by the above components are as follows: the electrostatic powder coating layer can not only improve the corrosion resistance of the noise reduction shell, resist the erosion of the shell by environmental factors such as moisture, acid and alkali, and extend the service life of the shell, but also enhance the wear resistance and smoothness of the shell surface, making it easy to clean and maintain daily, while not affecting the sound insulation effect of the noise reduction shell.

[0010] Preferably, the cover plate is fixedly installed with a sealing strip, and the cross-section of the sealing strip is U-shaped.

[0011] The effects achieved by the above components are as follows: the sealing strip can tightly fill the gap between the cover plate and the ultrasonic cleaner body, enhance the sealing between the soundproof cover plate and the ultrasonic cleaner body, completely prevent noise from leaking out from the gap at the connection, make up for the defect of noise leakage that is easy to occur in the opening and closing structure, and form a synergistic noise reduction effect with the soundproof cavity and soundproof cotton plug, further improving the overall sound insulation performance.

[0012] Preferably, the sound-absorbing cotton is made of polyester fiber.

[0013] The effects achieved by the above components are as follows: Polyester fiber sound-absorbing cotton has good sound absorption performance and flame retardancy. Its fluffy structure can efficiently absorb residual noise in the sound insulation cavity, especially the mid-to-high frequency noise generated by ultrasonic vibration, which has a significant absorption effect, further improving the noise reduction effect of the sound insulation cavity. At the same time, the material has good air permeability, and when filled in the sound insulation cavity, it will not hinder the heat dissipation of the machine body, ensuring smooth heat dissipation of the equipment and avoiding the impact of poor heat dissipation on the stability of equipment operation.

[0014] Preferably, rubber shock-absorbing pads are fixedly installed on the surfaces of all four base frames.

[0015] The effects achieved by the above components are as follows: The rubber shock-absorbing pads utilize the elastic buffering properties of rubber material to not only increase the friction when the cleaning machine is placed, improve the stability of the equipment placement, and effectively prevent displacement caused by vibration during operation, but also further play an auxiliary role in shock absorption, absorbing the vibration energy generated during equipment operation, reducing the transmission of vibration to the placement surface, reducing the noise caused by structural sound transmission from the root, and protecting the placement surface from wear.

[0016] Preferably, the surface of the ultrasonic cleaner body is provided with a plurality of heat dissipation holes evenly distributed, and a dustproof net is fixedly installed on the surface of the ultrasonic cleaner body by means of bolts.

[0017] The above components achieve the following effects: the heat dissipation holes can promptly expel the heat generated by the ultrasonic generator during operation, ensuring the heat dissipation requirements of the core components of the equipment and preventing the equipment from being affected by overheating, thus reducing its service life and working efficiency; the dustproof net can effectively block dust and particulate matter in the air from entering the machine body, preventing dust from adhering to the surface of electrical components and affecting their working performance, reducing the equipment failure rate; at the same time, the bolt fixing method facilitates the disassembly and cleaning of the dustproof net, making maintenance convenient.

[0018] Preferably, a sound-absorbing cover is fixedly installed on the surface of the dustproof net by means of bolts, and the sound-absorbing cover is coaxially arranged with the heat dissipation holes and the dustproof net.

[0019] The effect achieved by the above components is as follows: without blocking the heat dissipation holes or affecting air circulation and heat dissipation efficiency, the soundproof cover absorbs the electromagnetic noise and airflow noise generated when the ultrasonic generator is working through the internal sound absorption structure, fills the noise protection gap at the heat dissipation holes, further reduces the overall noise level of the equipment, and achieves the dual functions of heat dissipation and noise reduction, allowing the equipment to maintain a low noise state while operating stably.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting up components such as a noise-reducing shell and a sound-insulating cavity, a multi-layered noise-blocking structure is constructed, which can effectively block the propagation path of noise and reduce noise pollution caused by airborne and structural sound transmission at the source. Combined with the sound-absorbing design of the ventilation holes and sound-absorbing cotton plugs on the cover plate, a multi-directional noise reduction protection is formed, which further improves the noise reduction effect and provides operators with a quieter and more comfortable working environment in confined spaces or long-term work scenarios, reducing the impact of noise on the operator's hearing.

Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] like Figure 1-4As shown, this utility model provides a low-noise ultrasonic cleaner, including an ultrasonic cleaner body 1. Four base frames 15 are fixedly mounted on the surface of the ultrasonic cleaner body 1. A noise-reducing shell 2 is fixedly mounted on the surface of the ultrasonic cleaner body 1, forming a sound-insulating cavity 7 between the surface of the noise-reducing shell 2 and the ultrasonic cleaner body 1. The inner wall of the sound-insulating cavity 7 is filled with sound-absorbing cotton 6. A cover plate 3 is rotatably connected to the surface of the noise-reducing shell 2. Several vent holes 8 are evenly distributed on the surface of the cover plate 3, and sound-absorbing cotton plugs 9 are provided on the inner wall of the vent holes 8. A handle 4 is fixedly mounted on the surface of the cover plate 3. By setting up components such as the noise-reducing shell 2 and the sound-insulating cavity 7, a multi-layered noise-blocking structure is constructed, which can effectively block the propagation path of noise and reduce airborne sound transmission and noise at the source. The noise pollution caused by the sound transmission is mitigated by the combination of the ventilation holes 8 and the sound-absorbing cotton plugs 9 on the cover plate 3, forming a multi-faceted noise reduction protection. This further enhances the noise reduction effect, providing operators with a quieter and more comfortable working environment in confined spaces or long-term work scenarios, reducing the impact of noise on the operators' hearing. The surface of the noise-reducing shell 2 is covered with an electrostatic powder coating layer 5. This layer not only improves the corrosion resistance of the noise-reducing shell 2, resisting the erosion of the shell by environmental factors such as moisture and acids and alkalis, and extending the service life of the shell, but also enhances the wear resistance and smoothness of the shell surface, facilitating daily cleaning and maintenance, without affecting the sound insulation effect of the noise-reducing shell 2. A sealing strip 10 is fixedly installed on the cover plate 3. The cross-section of the sealing strip 10 is U-shaped. The sealing strip 10 tightly fills the gap between the cover plate 3 and the ultrasonic cleaner body 1, enhancing the sealing between them and completely preventing noise from leaking out. This compensates for the noise leakage inherent in open and closed structures, and works synergistically with the sound insulation cavity 7 and the sound-absorbing cotton plug 9 to further improve overall sound insulation performance. The sound-absorbing cotton 6 is made of polyester fiber, which has excellent sound absorption and flame retardancy. Its fluffy structure effectively absorbs residual noise in the sound insulation cavity 7, especially showing significant absorption of mid-to-high frequency noise generated by ultrasonic vibration, further enhancing the noise reduction effect of the sound insulation cavity 7. Simultaneously, this material has good air permeability and will not leak when filled in the sound insulation cavity 7. To prevent heat dissipation and ensure smooth heat dissipation, thus avoiding disruption to equipment stability due to poor heat dissipation, rubber shock-absorbing pads 11 are fixedly installed on the surfaces of the four base frames 15. These pads utilize the elastic cushioning properties of rubber to not only increase friction when the cleaning machine is placed, improving its stability and effectively preventing displacement due to vibration during operation, but also to further assist in shock absorption, absorbing vibration energy generated during operation and reducing the transmission of vibration to the placement surface. This reduces noise from structural sound transmission at its source and protects the placement surface from wear. The surface of the ultrasonic cleaning machine body 1 is evenly provided with several heat dissipation holes 12, and a dustproof net 13 is fixedly installed on the surface of the ultrasonic cleaning machine body 1 using bolts.The heat dissipation vents 12 effectively dissipate the heat generated by the ultrasonic generator during operation, ensuring the heat dissipation needs of the core components and preventing overheating from affecting the equipment's lifespan and efficiency. The dust filter 13 effectively blocks dust and particulate matter from entering the machine, preventing dust from adhering to the surface of electrical components and affecting their performance, thus reducing the equipment failure rate. The bolt-fixed design facilitates the disassembly and cleaning of the dust filter 13, making maintenance convenient. A silencer cover 14 is bolted to the surface of the dust filter 13. The silencer cover 14 is coaxially arranged with the heat dissipation vents 12 and the dust filter 13. Without obstructing the heat dissipation vents 12 or affecting airflow and heat dissipation efficiency, the silencer cover 14 absorbs the electromagnetic and airflow noise generated by the ultrasonic generator through its internal sound-absorbing structure, filling the noise protection gap at the heat dissipation vents 12 and further reducing the overall noise level of the equipment. This achieves the dual functions of heat dissipation and noise reduction, allowing the equipment to maintain a low-noise state while operating stably.

[0026] The overall working principle is as follows: when using an ultrasonic cleaner to clean parts, the soundproof cavity 7 formed between the noise-reducing outer shell 2 and the ultrasonic cleaner body 1, together with the polyester fiber sound-absorbing cotton 6 filled inside, blocks noise. The fluffy structure of the sound-absorbing cotton 6 can efficiently absorb the mid-to-high frequency noise generated by ultrasonic vibration, while blocking the noise from spreading outward through the air. After the cover plate 3 is closed, the sound-absorbing cotton plug 9 in the vent holes 8 on its surface further absorbs the noise overflowing from the top during equipment operation, and the U-shaped sealing strip 10 tightly fills the gap between the cover plate 3 and the body to prevent noise leakage from the connection, forming a top noise reduction and protection system. The rubber shock-absorbing pads 11 at the bottom of the four base frames 15 utilize the elastic buffering properties of rubber to absorb the vibration energy generated during equipment operation, reduce the transmission of vibration to the placement surface, reduce noise caused by structural sound transmission from the source, and improve the stability of equipment placement, avoiding displacement interference caused by vibration. The heat generated by the ultrasonic generator during operation is discharged in time through the heat dissipation holes 12 to ensure stable operation of the equipment. The coaxially set silencer 14 absorbs electromagnetic noise and airflow noise at the heat dissipation holes 12 without affecting the airflow of heat dissipation, filling the noise protection gap of the heat dissipation channel and achieving the dual effect of heat dissipation and noise reduction.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
