Description

Technical Field

[0001] This utility model relates to small ultrasonic cleaning equipment, and more particularly to a tabletop and built-in dual-purpose ultrasonic cleaning machine. Background Technology

[0002] Existing stainless steel ultrasonic cleaning machines generally employ a structure with a single metal casing and a drive board controlling 3-10 ultrasonic generators. While this structure is simple and low-cost, the difficulty in maintaining consistent parameters among multiple generators leads to uneven electric field distribution, resulting in decreased acoustic efficiency and necessitating extended cleaning times to meet cleanliness requirements. Furthermore, traditional models mount the control circuit board directly on the bottom of the casing, making them highly susceptible to moisture and corrosion under high temperature, high humidity, and oily conditions, resulting in a high failure rate. Additionally, the metal casing lacks effective sound insulation, leading to loud noise during operation and limiting its application to open spaces.

[0003] On the other hand, existing medium-capacity models ranging from 25L to 50L generally suffer from an awkward height issue: the tabletop is too high and the floor is too low. If they are made into embedded units, complex brackets are required, resulting in large installation gaps that are neither aesthetically pleasing nor convenient to operate. Drainage methods are mostly manual mechanical valves, requiring users to frequently bend over to open and close the valves when using embedded units, leading to a poor user experience. These structural and operational shortcomings fail to meet the demands of modern industry, medical settings, and laboratories for efficient, low-noise, easy-to-maintain, and dual-purpose (embedded / tabletop) ultrasonic cleaning equipment. Utility Model Content

[0004] To address the above-mentioned shortcomings, the purpose of this utility model is to facilitate user use and maintenance, and to meet the needs of flexible multi-scenario applications.

[0022] Housing and Support Frame: The stainless steel outer shell 36 (SUS304) and the stainless steel outer shell base plate 34 are fixed with screws to form a "U"-shaped main body. The four corner rivet nuts of the base plate 34 are locked into the conical rubber feet 33 (PVC-60°) to achieve tabletop anti-slip or embedded concealment. The front bracket 37, rear bracket 18, and side bracket 22 (modified PP) are respectively hot-pressed into the front aluminum alloy support plate 39, rear aluminum alloy support plate 19, and side aluminum alloy support plate 20 (AL2024, 2.5mm anodized), forming a "plastic shell + aluminum beam" composite frame. Each bracket has an 8mm horizontal overlap surface at the top edge, flush with the top edge of the stainless steel outer shell 36. Figure 3 This is a side view of a dual-purpose ultrasonic cleaner that can be embedded in a wall-mounted unit. Figure 4 This is a front view of the dual-purpose ultrasonic cleaner for both tabletop and built-in use. A silicone pad is attached to the bottom of the overlapping surface. When installed in the built-in position, it can be placed directly on the edge of the opening on the tabletop without the need for an additional bracket. When placed on the table, it serves as a non-slip support foot, achieving "dual-purpose with zero modification".

[0023] 1. Top Cover System: The top cover 2 (modified PP) and the top cover handle 1 are integrally injection molded; the inner panel 47 (SUS304) of the top cover is fixed to the bottom of the top cover 2 by snap-fit ​​around the perimeter, forming a double-layer sound insulation and chemical corrosion protection barrier. The rear edge is hinged to the rear of the stainless steel outer shell 36 by a stainless steel pivot, with an opening angle of 90°, which facilitates the loading and unloading of the stainless steel cleaning basket 46.

[0024] 2. Cleaning-Heating-Transducer System: At least one set of transducers is glued to the bottom of the stainless steel cleaning tank 45 (SUS304 mirror-finish stretched). Each set has 1 to 4 transducers; this embodiment uses 2 transducers as an example. Each set is connected to the corresponding drive board 16. The drive board 16 is a "universal board" with three pre-installed coil pads. Two transducers 40 can be driven by inserting magnetic rings of different inductances, with parameter consistency <3%, uniform cavitation field strength, and a 20% reduction in cleaning time. PTC heating blocks 150W41 and 250W42 are simultaneously riveted to the bottom of the tank and connected in parallel. The temperature is controlled by PID control on the control PCB board 11 with a temperature control accuracy of ±0.5℃. Dual temperature protection (software + 105℃ normally closed temperature control switch) and a 60-second delay for fan cooling after shutdown ensure stable and reliable continuous operation.

[0025] 3. Sound Insulation and Heat Dissipation System: Sound insulation and vibration damping plate 44 (butyl rubber, 1-4mm thick) is applied to the outer wall of the stainless steel cleaning tank 45 around the entire circumference, reducing the sound pressure level at 1m from 82dB(A) to 49dB(A). The rear shell 13 and front shell 43 of the electrical box (ABS AF312C flame retardant) are sealed with double stop + silicone ring, with an IP54 protection rating; DC12V 9225 fan 35 (12025, bottom exhaust) and DC12V 4020 cooling fan 12 (4020, side wall exhaust) form a vertical air duct, ensuring that the temperature rise of electrical components is ≤18K and preventing condensation during 24-hour continuous operation.

[0026] 4. Independent Electromagnetic Drainage System: The stainless steel drain outlet 24 is located at the lowest point of the tank bottom, and is connected in sequence to the drain outlet sealing ring 25 → pagoda head 26 → internal and external threaded union 29 → internal and external threaded union straight ball valve 30 → union internal and external threaded elbow 31 → drain right-angle elbow 32 → DC12 rotary valve 27 (12V normally closed solenoid valve). The DC12 rotary valve 27 is locked to the right side of the stainless steel housing 36 by a stainless steel fixing plate 28; the stainless steel self-locking switch 14 (with LED) is connected in series for control, allowing users to drain water without opening the cover, making maintenance convenient.

[0027] 5. Operation and Electrical System: A three-in-one AC socket 17 (fuse + switch + EMI filter) is embedded in the rear shell 13 of the electrical box; the control PCB board 11 is connected to the operation panel lens 9 (high-transmittance PETG) via a ribbon cable. An anti-accidental touch knob is composed of an outer knob cover 7, an inner knob cover 8, a knob fixing cover 5, and a stainless steel decorative ring 6. Functions include: 1-95℃ temperature setting, ±5℃ calibration, 1min-3h time setting, and degassing. All electrical components are located at the rear, away from the damp tank. The entire machine has passed a 48-hour constant humidity and heat test at 40℃ / 95%RH, resulting in a failure rate reduction of over 50%.

[0028] An optional stainless steel cleaning basket 46 (SUS304) can be added, which can be lifted and placed; a stainless steel filter screen 23 (80 mesh) is placed at the bottom of the basket to prevent debris from clogging the drain.

[0029] The unit can switch between desktop and embedded modes within 30 seconds without any tools or additional accessories, meeting the capacity requirements of a series of 16L-30L units.

[0030] The above-disclosed embodiments are merely one example of the present utility model and should not be construed as limiting the scope of the present invention. Those skilled in the art can understand that implementing all or part of the processes of the above embodiments and making equivalent changes in accordance with the claims of the present utility model still fall within the scope of the present utility model.
