Description

Technical Field

[0001] This utility model relates to the field of ultrasonic cleaning equipment technology, and in particular to an ultrasonic cleaning machine that combines aluminum alloy and plastic, which aims to solve the shortcomings of existing pure plastic, all-aluminum shell, or stainless steel in terms of structural strength, sealing performance, aesthetics and service life. Background Technology

[0002] Existing ultrasonic cleaners typically use pure plastic, all-aluminum, or stainless steel casings. While pure plastic casings are cheaper, they have the following problems: short lifespan, prone to yellowing and discoloration after prolonged use, especially in commercial and medical environments, which makes the equipment appear aged and affects its aesthetics and user experience; insufficient strength, easy deformation, and poor sealing performance, making it difficult to meet the demands of high-intensity use. All-aluminum casings, while strong, have the following problems: higher cost, with higher material and processing costs, hindering large-scale production and cost reduction; and heavier weight, reducing portability and increasing the user's burden. Utility Model Content

The bottom shell 31, made of ABS material, supports the entire equipment, ensuring its stability. The rubber elbow 30 connects to the outlet of the steel tank at one end and to the second direct connector 28 at the other. The entire assembly is located at the bottom and exposed, eliminating the need for disassembly for maintenance and repair.

[0031] The filter PCB board 32 and heater distribution board 33 are made of 94V material, managing power and signals to ensure normal equipment operation. The temperature sensor clamp 34 and temperature sensor 36 are made of PA+30% glass fiber and standard components, monitoring and controlling temperature to ensure precise control of the cleaning process. The adhesive-backed foam 35 is made of EVA material, providing heat insulation and shock absorption to protect internal components. The inner knob cover 37 and outer knob cover 38 are made of ABS material, protecting the knob and preventing dust and water ingress. The stainless steel decorative ring 39 is made of SUS 304 material, enhancing aesthetics. The knob fixing cover 40 is made of ABS material, securing the knob and ensuring its stability during use. The label 41 is made of PC material, providing product information for user understanding of the equipment.

[0032] The aluminum alloy front panel 42, made of AL6063 material, forms the front of the equipment, protecting internal components and providing an aesthetically pleasing appearance. The control box lens 43 is colorless and transparent, while the viewing window lens 44 is amber-colored and translucent, forming a double-layered waterproof structure that effectively protects the control PCB board and the digital tube PCB. The control PCB board 45, made of 94V material, manages the control logic, ensuring the normal operation of all equipment functions. The left side cover 46 and left side handle 47 are made of ABS material, protecting the left side of the equipment and facilitating transport. The main drive PCB board 48, made of 94V material, drives the main functions such as start, stop, and mode selection. The digital tube PCB board 49, made of 94V material, displays information such as equipment status and parameters. The stainless steel hexagonal screws 50, made of SUS 304 material, are used to secure structural components, ensuring the stability of the equipment.
