Description

Technical Field

[0001] This utility model relates to the field of ultrasonic cleaning technology, specifically to an ultrasonic cleaning water tank that can reduce local pitting corrosion in the tank. Background Technology

[0002] With the rapid development of science and technology, ultrasonic technology has been increasingly applied in the cleaning industry. It primarily uses transducers to convert the acoustic energy of ultrasonic frequencies into mechanical vibrations, which then clean the objects inside the cleaning tank by passing through the tank walls. Water tanks with ultrasonic cleaning capabilities are widely used for cleaning precision parts, medical devices, laboratory equipment, and other items.

[0003] In existing ultrasonic cleaning tanks, there are two main methods for bonding the ultrasonic transducer to the tank body: one is to directly bond the transducer to the back of the tank body; the other is to spot weld studs to the back of the tank body, then fix the transducer with the studs and apply adhesive around the perimeter to enhance the connection. Of these two methods, the first method suffers from weak adhesion and easy loosening, leading to equipment failure or even safety accidents. While the second method provides a more secure connection, the localized high temperatures (reaching over 1400℃) during the spot welding process can cause microscopic damage and stress concentration in the tank material, leading to pitting corrosion. This corrosion is accelerated by ultrasonic cavitation, ultimately resulting in tank perforation and equipment failure. Furthermore, inconsistent welding quality can lead to uneven vibration transmission, poor cleaning effect, high energy consumption, and high noise levels. Utility Model Content

[0004] To address some or all of the problems existing in the prior art, this utility model provides an ultrasonic cleaning tank that can reduce local pitting corrosion in the tank body. The tank body includes a cleaning tank and an ultrasonic transducer. A metal sheet is adhered to the lower outer surface of the cleaning tank body. The surface area of ​​the metal sheet is larger than the end face area of ​​the ultrasonic transducer. Multiple reinforcing lugs are provided along the edge of the metal sheet. These lugs are spot-welded to the lower outer surface of the cleaning tank body. A fixing member is welded to the center of the surface of the metal sheet on the side away from the cleaning tank body. The ultrasonic transducer is connected to the fixing member, and the end face of the ultrasonic transducer is in contact with the metal sheet.

[0005] As a further improvement of this utility model, the end face of the ultrasonic transducer is bonded and fixed to the surface of the metal sheet.

[0006] As a further improvement of this utility model, the reinforcing lug is fixed to the lower outer surface of the cleaning tank by laser welding or brazing spot welding.

[0007] As a further improvement of this utility model, there are three reinforcing lugs, and the three reinforcing lugs are distributed in a circumferential array on the edge of the metal sheet.

[0008] As a further improvement of this utility model, the material of the metal sheet is stainless steel.

[0009] As a further improvement of this utility model, the thickness of the metal sheet is less than or equal to 1 mm.

[0010] As a further improvement of this utility model, the surface area of ​​the metal sheet is at least 1.2 times the end face area of ​​the ultrasonic transducer.

[0011] As a further improvement of this utility model, the fixing member is a stud, and the ultrasonic transducer is threadedly connected and fixed to the fixing member.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this invention, the metal sheet and the tank body are mainly connected by adhesive bonding. The reinforcing lugs are spot-welded to the tank body only for auxiliary reinforcement, and low-heat-input laser welding or brazing is used. The fixing bracket is welded to the metal sheet rather than directly to the tank body, avoiding direct thermal damage to the tank body. This invention can greatly reduce the thermal impact and structural damage to the tank body, thereby reducing the problem of pitting corrosion and extending the service life of the tank body.

[0014] 2. By setting a metal sheet, this utility model can increase the vibration transmission area, making the ultrasonic energy distribution more uniform, the cleaning efficiency higher, and the energy consumption lower.

[0015] 3. This product has a simple structure, low cost, and can be made from scraps, making it economical and environmentally friendly. Attached Figure Description

Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

[0018] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used in the specification is for the purpose of describing particular embodiments only and is not intended to limit the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0019] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, an ultrasonic cleaning tank capable of reducing localized pitting corrosion includes a cleaning tank body 1 and an ultrasonic transducer 2. A metal sheet 3 is bonded to the lower outer surface of the cleaning tank body 1 using a high-strength adhesive. This metal sheet 3 is preferably made of stainless steel and can be made from scraps from the production process of the ultrasonic cleaner's housing. The thickness of the metal sheet 3 does not exceed 1 mm, and the surface area of ​​the metal sheet 3 should be at least 1.2 times the end face area of ​​the ultrasonic transducer 2. Furthermore, the surface area of ​​the metal sheet 3 should be greater than the radiation area of ​​the ultrasonic transducer 2 to ensure sufficient vibration transmission area and structural stability. The metal sheet 3 can be made into a circular, square, or other regular shape.

[0022] Three reinforcing lugs 31 are provided on the edge of the metal sheet 3, and the three reinforcing lugs 31 are distributed in a circumferential array along the circumferential edge of the metal sheet 3. In other embodiments, the number of reinforcing lugs 31 can also be any other number. The reinforcing lugs 31 are spot welded to the lower outer surface of the cleaning tank 1 by laser spot welding or brazing.

[0023] It should be noted that the metal sheet 3 and the cleaning tank 1 are mainly bonded and fixed by high-strength adhesive; the spot welding between the metal sheet 3 and the tank is mainly used for auxiliary reinforcement, and brazing or laser welding with a very small heat-affected zone is adopted. The welding area is small and the heat input is low, which will not cause significant heat impact on the tank material, thereby avoiding microstructural damage and pitting corrosion origin.

[0024] A fixing element 4 is welded to the center of the side of the metal sheet 3 facing away from the cleaning tank 1. In this embodiment, the fixing element 4 is a stud; in other embodiments, the fixing element 4 can also be other mechanical structures that can be connected and fixed to the ultrasonic transducer 2. The ultrasonic transducer 2 is mechanically connected to the fixing element 4 through the threaded hole on its housing, so that the ultrasonic transducer 2 is connected and fixed to the metal sheet 3, that is, connected and fixed to the cleaning tank 1; at the same time, an adhesive is applied between the end face of the ultrasonic transducer 2 and the metal sheet 3, so that the end face of the ultrasonic transducer 2 is bonded and fixed to the surface of the metal sheet 3, further ensuring the firmness of the connection and the vibration transmission efficiency.

[0025] The work process is as follows:

[0026] When the ultrasonic transducer 2 is powered on, it generates high-frequency mechanical vibration, which is transmitted to the cleaning tank 1 through the fixing component 4 and the metal plate 3. Because the metal plate 3 has a large area and is well bonded to the tank, the vibration is evenly distributed throughout the bottom of the tank, avoiding excessive local stress and effectively inhibiting cavitation corrosion. The spot-welded structure of the three reinforcing lugs 31 ensures connection strength while minimizing the risk of damage to the tank material.

[0027] This invention significantly reduces the probability of pitting corrosion in the cleaning tank 1 while ensuring structural reliability through a composite connection method (adhesion + limited spot welding), thereby improving cleaning efficiency and equipment lifespan. It has high practicality and economy.

[0028] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
