Description

Technical Field

[0001] This utility model relates to the field of ultrasonic cleaning, specifically an ultrasonic cleaning machine. Background Technology

[0002] An ultrasonic cleaner is a device that uses high-frequency ultrasonic vibration to generate cavitation effect in the cleaning fluid, thereby achieving efficient cleaning. Its working principle is to convert electrical energy into mechanical vibration through a transducer, causing the cleaning fluid to generate dense microbubbles that burst instantly, releasing a powerful impact force to remove stains, grease, or particles from the surface of objects.

[0003] Existing ultrasonic cleaners typically have a cleaning tank and a mounting bracket. The cleaning tank and the mounting bracket together form a mounting cavity for installing the electronic control module, thus achieving concealed installation and protection of the electronic control module. However, due to the lack of a reliable sealing structure at the connection between the cleaning tank and the mounting bracket, moisture generated during the operation of the ultrasonic cleaner can easily seep into the mounting cavity through the gap between the two, causing the electronic control module to become damp and short-circuit. This not only affects the normal operation of the ultrasonic cleaner but also shortens the service life of the equipment.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] The aforementioned problem arises because existing ultrasonic cleaners often lack a reliable sealing structure at the connection between the water tank and the mounting bracket, allowing moisture to easily seep into the mounting cavity through the gap between the water tank and the bracket, leading to moisture-induced short circuits in the electronic control module. The technical solution adopted by this invention to solve this problem is as follows: An ultrasonic cleaner includes a water tank, a mounting base, and a mounting bracket. The mounting base and the bottom of the water tank form a mounting cavity for accommodating an electronic control module. Double-sided adhesive tape is provided between the mounting base and the water tank. One side of the mounting bracket is connected to the bottom of the water tank, and the other side of the mounting bracket is connected to the mounting base to press the mounting base and the water tank tightly together.

[0006] Furthermore, a transducer is provided inside the mounting cavity, the mounting bracket is located inside the mounting cavity, the transducer is fixedly installed at the bottom of the water tank of the cleaning machine, an adhesive is provided between the mounting bracket and the water tank of the cleaning machine, and an elastic shock absorber is provided between the transducer and the mounting bracket.

[0007] Furthermore, the mounting bracket is provided with a first mating part, and the mounting support is provided with a second mating part. The first mating part and the second mating part cooperate to make the mounting bracket and the mounting support detachably connected.

[0008] Furthermore, the mounting bracket is provided with an avoidance opening and a mounting part, the transducer is located in the avoidance opening, the elastic damping member is provided on the mounting part, and the mounting part communicates with the avoidance opening.

[0009] Furthermore, the mounting bracket is provided with an adhesive injection mechanism, which includes an adhesive injection port and an adhesive joint connected to the adhesive injection port. The adhesive joint is used to increase the contact area between the mounting bracket and the adhesive and is inclined.

[0010] Furthermore, the mounting part is a mounting groove, which extends along the circumferential direction of the clearance opening.

[0011] Furthermore, the glue injection mechanism includes a glue joint groove communicating with the glue injection port, the glue joint portion being located within the glue joint groove and extending along the depth direction of the glue joint groove.

[0012] Furthermore, multiple glue injection mechanisms are provided, and these multiple glue injection mechanisms are spaced apart along the circumferential direction of the mounting bracket.

[0013] Furthermore, the water tank of the cleaning machine is made of glass.

[0014] Furthermore, the elastic damping element is a foam strip.

[0015] The beneficial effects of this utility model are as follows: This invention utilizes double-sided adhesive tape between the mounting bracket and the cleaning machine's water tank. This tape fills the tiny gaps at the connection point, forming a primary sealing layer. Combined with the clamping action of the mounting bracket, one side of the bracket connects to the bottom of the cleaning machine's water tank, and the other side connects to the mounting bracket.

Detailed Implementation

[0018] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figures 1 to 10 An ultrasonic cleaner is shown, including a cleaning machine tank 1, a mounting base 2, and a mounting bracket 3. The mounting base 2 and the bottom of the cleaning machine tank 1 form a mounting cavity 11 for accommodating an electronic control module. Double-sided adhesive tape 4 is provided between the mounting base 2 and the cleaning machine tank 1. One side of the mounting bracket 3 is connected to the bottom of the cleaning machine tank 1, and the other side of the mounting bracket 3 is connected to the mounting base 2 to press the mounting base 2 and the cleaning machine tank 1 tightly together. This invention utilizes double-sided adhesive tape between the mounting bracket and the cleaning machine's water tank. This tape fills the tiny gaps at the connection point, forming a primary sealing layer. Combined with the clamping action of the mounting bracket, one side of the bracket connects to the bottom of the cleaning machine's water tank, and the other side connects to the mounting bracket. This ensures the double-sided adhesive tape adheres tightly to the contact surfaces, effectively eliminating gaps and leaks. The dual structure together creates a sealing structure, preventing moisture generated during ultrasonic cleaning from seeping into the mounting cavity. This effectively solves the problem that existing ultrasonic cleaners often lack a reliable sealing structure at the connection between the cleaning machine's water tank and the mounting bracket, allowing moisture to easily seep into the mounting cavity through the gap, leading to moisture-induced short circuits in the electronic control module.

[0020] Furthermore, the mounting bracket 3 connects the bottom of the cleaning machine water tank 1 to the mounting support 2, forming a stable overall structure between the cleaning machine water tank 1 and the mounting support 2. Compared to the connection method that relies solely on adhesive, this can effectively resist the vibration and impact during equipment transportation or operation, and prevent the mounting support 2 from shifting and causing seal failure. Secondly, the mounting bracket 3 helps ensure that the double-sided adhesive tape 4 is always in a tight fit, avoiding gaps due to adhesive aging during long-term use, and thus extending the service life of the sealing structure.

[0021] Furthermore, the double-sided adhesive tape 4 is a pre-made pressure-sensitive adhesive tape, which does not require on-site dispensing, curing, or the use of fasteners. After simply removing the release paper, it can be directly attached between the mounting bracket 2 and the bottom wall of the water tank 1 of the cleaning machine, which can achieve quick and tool-free assembly and help shorten the assembly time.

[0022] Furthermore, compared to mechanical connection methods such as screws or riveting, the use of double-sided adhesive tape 4 eliminates the need to drill holes in the water tank 1 of the cleaning machine, effectively avoiding structural strength reduction, water leakage hazards, or stress concentration problems caused by drilling, and helping to ensure the integrity of the bottom of the water tank 1 of the cleaning machine and long-term sealing reliability.

[0023] Furthermore, the double-sided adhesive tape 4 forms a continuous and uniform adhesive layer on the contact surface, resulting in a more balanced force distribution. Secondly, its adhesive layer has a certain degree of elasticity, which can absorb some of the vibration and impact from the mounting bracket 2 or the outside, thus reducing noise transmission and improving the overall stability of the machine's operation.

[0024] Specifically, the cleaning tank 1 is mainly used to hold items to be cleaned, such as electronic components, precision parts, jewelry, etc., as well as cleaning fluid, providing a closed and stable working space for ultrasonic cleaning; it works in conjunction with the bottom transducer 5 to enable the ultrasonic waves generated by the transducer 5 to propagate efficiently in the cleaning fluid, and achieve the cleaning of items by means of cavitation effect.

[0025] like Figures 1 to 10The mounting cavity 11 shown is provided with a transducer 5, the mounting bracket 3 is located in the mounting cavity 11, the transducer 5 is fixedly installed at the bottom of the cleaning machine water tank 1, an adhesive is provided between the mounting bracket 3 and the cleaning machine water tank 1, and an elastic shock absorber 6 is provided between the transducer 5 and the mounting bracket 3. Specifically, in existing ultrasonic cleaners, the transducer 5 and the mounting bracket 3 are respectively bonded to the bottom of the cleaning tank 1 by applying adhesive to achieve structural stability and vibration transmission. However, in some small or compact ultrasonic cleaners, due to the small gap between the mounting bracket 3 and the transducer 5, the adhesive easily overflows and fills the space between them during the adhesive application process. This causes the mounting bracket 3 and the transducer 5 to be rigidly connected by the adhesive, thus restricting the free vibration of the transducer 5 and resulting in poor vibration performance. In contrast, this invention provides an elastic damping element 6 between the transducer 5 and the mounting bracket 3. The elastic damping element 6 can physically isolate the transducer 5 from direct contact with the mounting bracket 3, which helps to avoid accidental rigid adhesion caused by adhesive overflow. In addition, the elastic damping element 6 has good elasticity and flexibility, which can provide sufficient vibration space for the transducer 5, avoid the rigid constraint of the mounting bracket 3 on the vibration of the transducer 5, and allow the transducer 5 to vibrate freely, which helps to improve vibration transmission efficiency.

[0026] Optionally, in some embodiments, the elastic damping element 6 is a silicone rubber gasket, which is an integrally molded ring structure made of high-purity silicone material. Silicone rubber has excellent high and low temperature resistance, aging resistance and chemical stability. Even in high-frequency vibration environment, it can still maintain stable elasticity and sealing performance. The silicone rubber gasket is tightly attached between the transducer 5 and the mounting bracket 3 to achieve flexible isolation.

[0027] Optionally, in some embodiments, the elastic damping element 6 is a rubber damping pad. The rubber damping pad is made of nitrile rubber and has a sheet-like structure with uniformly distributed protruding particles on its surface. During installation, the rubber damping pad is sandwiched between the transducer 5 and the mounting bracket 3. The protruding particles can increase the contact gap. When the adhesive is applied, it only fills the gap between the particles, thus preventing the transducer 5 from directly adhering to the mounting bracket 3.

[0028] Optionally, in some embodiments, the elastic damping element 6 is a damping strip made of thermoplastic elastomer (TPE) material, which is formed by extrusion or molding into an arc or ring structure that matches the outer contour of the transducer 5 or the inner sidewall of the mounting bracket 3. The TPE damping strip has moderate hardness and excellent dynamic resilience, forming a stable elastic interface between the transducer 5 and the mounting bracket 3, which not only prevents rigid adhesion caused by adhesive overflow, but also avoids permanent material deformation due to long-term vibration.

[0029] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the elastic shock absorber 6 is a foam strip.

[0030] Furthermore, the use of adhesive connections eliminates the need for mechanical fixing structures such as screws and clips, avoiding the need to drill holes or add complex assembly structures at the bottom of the water tank 1 of the cleaning machine. This simplifies the overall structural design, helps reduce the number of parts and assembly difficulty, and eliminates the risk of water leakage caused by drilling holes, effectively improving the reliability of the seal.

[0031] Optionally, in some embodiments, the adhesive is a silicone sealant, which has good elasticity, strong weather resistance and excellent waterproof performance, and is suitable for connection parts that require a certain degree of flexibility and sealing.

[0032] Optionally, in some embodiments, the adhesive is polyurethane adhesive. The high flexibility of polyurethane adhesive can adapt to the vibration and impact during equipment transportation, and it is not easy to crack under long-term high-frequency vibration environment, which is conducive to ensuring the long-term stable connection between the mounting bracket 3 and the bottom of the cleaning machine water tank 1.

[0033] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the adhesive is an epoxy resin adhesive. Epoxy resin adhesive has advantages such as high strength, water resistance, aging resistance and low shrinkage. After curing, it can form a rigid structure and is suitable for occasions requiring high bonding strength.

[0034] like Figures 1 to 10 The mounting bracket 2 shown is provided with a first mating part 21, and the mounting bracket 3 is provided with a second mating part 31. The first mating part 21 and the second mating part 31 are mated to make the mounting bracket 2 and the mounting bracket 3 detachably connected. Furthermore, the first mating part 21 and the second mating part 31 can form a mechanical interlock through snap-fit, plug-in, threaded and other mating methods. While ensuring disassembly, it ensures that the connection part does not loosen or shift under ultrasonic high-frequency vibration conditions, which is conducive to maintaining the sealing integrity and structural rigidity of the mounting cavity 11.

[0035] Optionally, in some embodiments, the first mating part 21 is an elastic buckle provided on the mounting bracket 2, and the second mating part 31 is a slot provided on the mounting bracket 3; during assembly, the elastic buckle is inserted into the slot and hooks onto the slot wall, relying on the elasticity of the material to achieve locking; during disassembly, pressing the buckle will disengage it.

[0036] Optionally, in some embodiments, the first mating part 21 is a tongue provided on the mounting bracket 2, and the second mating part 31 is a corresponding slot on the mounting bracket 3; during assembly, it slides in along the guide direction to form an anti-disengagement limit.

[0037] Optionally, in some embodiments, the first mating part 21 is a permanent magnet embedded in the mounting bracket 2, and the second mating part 31 is a ferromagnetic metal sheet on the mounting bracket 3. The two are detachably connected by magnetic attraction.

[0038] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the first mating part 21 is a connecting post disposed on the mounting support 2, and the second mating part 31 is a connecting post disposed on the mounting bracket 3. Both the first mating part 21 and the second mating part 31 are provided with threaded holes at their axial centers. During assembly, the mounting bracket 3 and the mounting support 2 are aligned so that the end faces of the two connecting posts abut or fit together. Then, screws are passed through the through holes in sequence or screwed directly in to engage with the two threaded holes and lock them in place, thereby detachably and fixedly connecting the mounting support 2 and the mounting bracket 3.

[0039] like Figures 1 to 10 The mounting bracket 3 shown is provided with a clearance opening 32 and a mounting part. The transducer 5 is located in the clearance opening 32, and the elastic damping member 6 is provided on the mounting part. The mounting part communicates with the clearance opening 32. Furthermore, the elastic damping component 6 is located in the mounting section, precisely at the gap between the outer periphery of the transducer 5 and the inner sidewall of the mounting bracket 3. It can physically block the adhesive from flowing into the gap between the transducer 5 and the mounting bracket 3, fundamentally preventing the two from forming a rigid connection due to adhesive adhesion.

[0040] Furthermore, since the elastic damping element 6 is stably installed in the mounting section and can be in close contact with the transducer 5, it maintains good elastic support while achieving isolation, so that the transducer 5 obtains stable vibration boundary conditions during operation, which is beneficial to reducing energy loss and improving ultrasonic cavitation efficiency.

[0041] Optionally, in some embodiments, the mounting part is designed to avoid the annular or segmented planar recessed area formed by the partial sinking of the periphery of the opening 32, with a flat surface and no sidewalls; the elastic damping element 6 is directly attached to the platform by adhesive.

[0042] Optionally, in some embodiments, the mounting part is an L-shaped stepped structure machined at the edge of the clearance opening 32, including a horizontal bottom wall and a vertical side wall, thereby forming an "L" shaped cross section; the elastic damping member 6 sits on the bottom wall and is limited by the side wall to prevent it from moving axially or radially.

[0043] Optionally, in some embodiments, the mounting portion is an annular groove formed on the mounting bracket 3 and surrounding the inner periphery of the clearance opening 32. The elastic damping member 6 is embedded in the groove, with its outer side abutting against the outer wall of the transducer 5 and its inner side limited by the groove wall.

[0044] Optionally, in some embodiments, the mounting part is composed of multiple arc-shaped grooves spaced apart along the circumferential direction of the clearance opening 32, each groove being arc-shaped and matching the outer contour of the transducer 5; the elastic damping member 6 is embedded in each arc-shaped groove.

[0045] like Figures 1 to 10 The mounting bracket 3 shown is provided with an adhesive injection mechanism. The adhesive injection mechanism includes an adhesive injection port 331 and an adhesive joint 332 connected to the adhesive injection port 331. The adhesive joint 332 is used to increase the contact area between the mounting bracket 3 and the adhesive and is inclined. Furthermore, the adhesive portion 332 increases the contact area with the adhesive, thereby forming a more stable "surface contact" adhesive structure. Compared with traditional planar adhesive bonding, this is beneficial to improving the connection strength between the mounting bracket 3 and the bottom of the cleaning machine water tank 1. It can effectively resist the peeling force caused by the high-frequency vibration generated when the transducer 5 is working, avoid delamination and loosening problems during long-term use, and help ensure the connection stability between the mounting bracket 3 and the bottom of the cleaning machine water tank 1.

[0046] Furthermore, the injection port 331 provides a dedicated channel for adhesive injection, enabling directional injection, which helps users control the amount of adhesive and observe the filling status, thus reducing the risk of adhesive overflow or insufficient adhesive.

[0047] Optionally, in some embodiments, the adhesive part 332 has a vertically downward plate-like structure, perpendicular to the bottom end face of the water tank 1 of the cleaning machine, and its inner wall is a flat and smooth vertical surface. During installation, the adhesive is injected through the injection port 331 and flows along the inner wall of the vertical adhesive part 332, evenly filling the gap between the mounting bracket 3 and the bottom of the water tank 1 of the cleaning machine. The adhesive part 332 can be integrally formed by mold, and the vertical surface can provide a stable adhesion base for the adhesive.

[0048] Furthermore, the adhesive portion 332 is inclined relative to the bottom end face of the water tank 1 of the cleaning machine.

[0049] Furthermore, the adhesive part 332 is inclined, which allows the adhesive to form a larger effective bonding surface within the injection port 331. Compared with vertical or planar structures, the adhesive per unit volume can cover a longer interface path, thereby enhancing the bonding force between the mounting bracket 3 and the cleaning machine water tank 1, which is beneficial to improving the overall structural stability.

[0050] Furthermore, the wedge-shaped or trapezoidal adhesive layer structure formed between the inclined adhesive part 332 and the bottom wall of the washing machine water tank 1 can better disperse stress when subjected to vibration or external force, which is beneficial to improving shear resistance and peel resistance.

[0051] Optionally, in some embodiments, the adhesive portion 332 is an integral inclined plate-like structure disposed on one side of the inner wall of the glue injection port 331, and its surface is inclined at 30°-70° relative to the bottom wall of the water tank 1 of the cleaning machine. This structure is simple to process and can effectively increase the bonding area on one side.

[0052] Optionally, in some embodiments, the adhesive portion 332 is an inwardly concave arc or spherical curved surface of the inner wall of the glue injection port 331. The surface is generally concave and inclined. This curved surface structure can guide the adhesive to converge to the bottom, forming an adhesive layer of moderate thickness, avoiding adhesive accumulation or loss, and increasing the actual contact area through the curved surface.

[0053] Optionally, in some embodiments, the adhesive portion 332 includes a first adhesive portion and a second adhesive portion, which are arranged opposite to each other and have a cross-section in the shape of an "eight". Compared with a single inclined surface or a planar structure, the first adhesive portion and the second adhesive portion arranged opposite to each other in the shape of an "eight" are conducive to forming a bidirectional inclined composite adhesive surface, which helps to increase the contact area with the adhesive. Secondly, the bidirectional inclined structure can make the adhesive form a "wedge filling" effect between the first adhesive portion and the second adhesive portion, thereby enhancing the bonding force between the adhesive and the mounting bracket 3, which is beneficial to resisting the risk of delamination caused by long-term high-frequency vibration of the ultrasonic cleaner, and effectively improving the connection stability between the mounting bracket 3 and the bottom of the water tank 1 of the cleaner.

[0054] like Figures 1 to 10 The mounting part shown is a mounting groove 34, which extends along the circumferential direction of the clearance opening 32; Furthermore, the mounting groove 34 extends along the circumference of the clearance opening 32 to form an annular structure, which enables the elastic damping element 6 to fit in an annular shape against the side wall of the transducer 5, achieving full-circumferential wrapping positioning. Compared with the partial mounting structure, the annular mounting groove 34 can evenly distribute the damping support force on the transducer 5, avoiding displacement or jamming caused by uneven force during vibration, ensuring that the transducer 5 vibrates stably at high frequency along the axis, which is beneficial to improving the consistency of vibration transmission.

[0055] Furthermore, the mounting groove 34 and the clearance opening 32 are integrated, eliminating the need for additional positioning components. The elastic damping component 6 can be quickly embedded and installed using only the annular groove, which simplifies the assembly process. Secondly, the annular structure does not occupy the internal space of the clearance opening 32 and does not affect the installation depth and vibration stroke of the transducer 5, perfectly adapting to the layout requirements of small or compact ultrasonic cleaning machines.

[0056] Furthermore, the annular mounting groove 34 can circumferentially limit the elastic damping component 6, preventing the elastic damping component 6 from shifting or falling off due to equipment transportation or long-term high-frequency vibration; secondly, the side wall of the annular groove can disperse the impact force generated when the transducer 5 vibrates, which is beneficial to reducing the local stress concentration of the mounting bracket 3 and helping to improve the structural strength of the mounting bracket 3.

[0057] Optionally, the mounting groove 34 includes multiple arc-shaped groove segments, which are spaced apart along the circumferential direction of the clearance opening 32. Specifically, a single foam strip is embedded in multiple spaced arc-shaped groove segments. The arc-shaped groove segments achieve full circumferential contact between the foam strip and the transducer 5 sidewall through multi-point limiting, which not only prevents the foam strip from shifting, but also allows the foam strip to undergo elastic deformation with the high-frequency vibration of the transducer due to the small deformation space reserved between the arc-shaped groove segments, without forming a rigid constraint. Compared with a continuous annular groove, the spaced structure helps to reduce the contact area between the foam strip and the mounting bracket 3. This helps reduce vibration energy loss and effectively ensures the free vibration of transducer 5. Furthermore, multiple arc-shaped grooves do not require integral molding of a complete annular groove, reducing processing difficulty and not occupying additional installation space, perfectly fitting the compact layout of small ultrasonic cleaners. Secondly, a single foam strip can be directly embedded into all arc-shaped grooves without the need for segmented cutting and splicing, which helps reduce assembly steps and dimensional deviation risks. At the same time, the continuity of the foam strip ensures the integrity of gap filling, helping to avoid sealing leaks caused by segmented splicing, effectively improving assembly efficiency and reliability.

[0058] like Figures 1 to 10 The glue injection mechanism shown includes a glue groove 333 communicating with the glue injection port 331, and the glue part 332 is located in the glue groove 333 and extends along the depth direction of the glue groove 333. Furthermore, the adhesive groove 333 provides a space for the adhesive, and the inclined adhesive part 332 extends along the depth of the groove, which not only increases the contact area with the adhesive, but also forms an "interlocking" structure. After the adhesive is cured, it is tightly bonded to the adhesive part and the wall of the adhesive groove, forming a three-dimensional bonding effect. This can effectively resist the peeling force caused by the high-frequency vibration of the transducer 5, prevent the mounting bracket 3 from delaminating with the water tank 1 of the cleaning machine, and ensure the stability of the connection.

[0059] Furthermore, the adhesive groove 333 can hold an appropriate amount of adhesive, which, together with the precise flow guidance of the glue inlet 331, allows the adhesive to evenly fill the gaps in the groove along the inclined adhesive part 332, reducing defects such as air bubbles and voids. Secondly, the design of the adhesive part 332 extending along the depth of the groove allows the adhesive to form a multi-layer seal in the depth direction. Combined with the blocking effect of the adhesive groove 333, it completely blocks the path of moisture seeping into the installation cavity 11, preventing the electronic control module from getting damp and short-circuiting.

[0060] Furthermore, the adhesive groove 333 and the adhesive part 332 are integrated into one piece, which can be molded in one piece, simplifying the processing technology and eliminating the need for additional adhesive components. Secondly, the groove structure does not occupy too much space, which helps to adapt to the compact layout of small ultrasonic cleaning machines. Finally, the adhesive is injected directly into the groove through the injection port 331, which is convenient to operate, eliminates the need for complex positioning, and effectively improves assembly efficiency.

[0061] like Figures 1 to 10 The shown glue injection mechanism is provided in multiple ways, and the multiple glue injection mechanisms are spaced apart along the circumferential direction of the mounting bracket 3; Furthermore, multiple adhesive injection mechanisms are arranged at intervals along the circumference, allowing the adhesive to be injected simultaneously or in stages from multiple directions. This avoids uneven filling, cavities, or air bubble accumulation caused by single-point injection, which helps ensure a continuous and dense adhesive layer between the mounting bracket 3 and the bottom wall of the cleaning machine water tank 1, and helps improve the overall connection strength and structural stability.

[0062] Furthermore, when the ultrasonic cleaner is working, the high-frequency vibration of the transducer 5 is transmitted to the mounting bracket 3, thereby generating a dynamic load. The multiple circumferentially distributed glue inlets 331 form a multi-point anchoring effect, making the force on the bonding area more balanced in the circumferential direction, effectively suppressing the slight rotation or displacement of the mounting bracket 3 during vibration, which is conducive to improving the stability and durability of the equipment operation.

[0063] Furthermore, in small or compact ultrasonic cleaners, the contact area between the mounting bracket 3 and the water tank 1 of the cleaner is limited, and single-point glue application is difficult to guarantee sufficient bonding strength. By applying glue at multiple points around the perimeter, the bonding interface can be maximized within a limited space, thereby improving the connection reliability without increasing the size of the mounting bracket 3.

[0064] like Figures 1 to 10 The water tank 1 of the cleaning machine shown is made of glass. Furthermore, the glass material has excellent transparency, allowing users to clearly observe the cleaning status of the workpieces, the removal of dirt, and the flow of cleaning fluid in the water tank 1 of the cleaning machine without opening the equipment, which helps to improve ease of use and operational safety.

[0065] Furthermore, glass has extremely strong resistance to water, acids, alkalis and common cleaning agents, and is not easily corroded, swollen or aged. It does not leach harmful substances during long-term use, which helps to ensure the purity of the cleaning solution and the life of the equipment.

[0066] Furthermore, glass has high acoustic impedance matching, and is less prone to stray resonance or energy loss under high-frequency vibration, which helps transducer 5 to efficiently transmit ultrasonic energy to the cleaning fluid and helps ensure the cleaning effect.

[0067] like Figures 1 to 10The elastic damping element 6 shown is a foam strip; Furthermore, the foam strip has a porous and loose structure, which can tightly fill the narrow gap between the transducer 5 and the mounting bracket 3. When applying adhesive, the foam strip can absorb a small amount of overflowing adhesive, preventing the adhesive from spreading to the contact surface of the two and forming a rigid connection. At the same time, the physical isolation effect of the foam strip can block the flow path of the adhesive, ensuring that the transducer 5 and the mounting bracket 3 remain relatively independent, which helps to solve the vibration restriction problem caused by adhesion.

[0068] Furthermore, the foam strip is small in size and flexible, and can be flexibly cut according to the gap between the transducer 5 and the mounting bracket 3. It can be embedded and installed without additional processing of complex structures. Its softness can adapt to irregular installation gaps without increasing the size of the equipment. It perfectly fits the layout requirements of small or compact ultrasonic cleaners, and the installation process does not require professional tools, which helps to improve assembly efficiency.

[0069] Furthermore, the foam strip has good elastic deformation and resilience, which can provide sufficient buffer space when the transducer 5 vibrates at high frequency, absorb the vibration impact force, and avoid the rigid constraint of the mounting bracket 3 on the transducer 5. At the same time, its low hardness will not hinder the vibration stroke of the transducer 5, which is conducive to ensuring that the transducer 5 vibrates freely at the design frequency and helps to reduce vibration energy loss.

[0070] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments.
