Description

Technical field

[0001] The present invention relates to the field of automatic cleaning machines, in particular to an automatic elevator handrail cleaning machine based on ultrasonic principles. [Background Technology]

[0002] In daily life, we can observe that the cleanliness of supermarket escalator handrails continues to be a problem that needs improvement. Most escalator handrails are cleaned by first wiping them with a damp cloth, then applying polish with a dry cloth after drying, and then wiping them again with a dry cloth after the polish has dried. This cleaning method requires considerable manpower, is ineffective, and results in low-quality cleaning. Some supermarkets even neglect to clean their escalator handrails, resulting in excessive bacterial counts on the handrails, some even approaching contamination levels. Since there are currently no mandatory regulations for the cleanliness of supermarket escalator handrails, it is generally impossible for supermarkets to regularly clean and disinfect them daily.

[0003] An investigation of existing cleaning machines on the market revealed that few are specifically designed to clean escalator handrails. Even those that do exist only perform simple scrubbing operations similar to manual operations, resulting in ineffective cleaning results. Therefore, developing an ultrasonic-based automatic cleaning machine for supermarket escalator handrails is of great value and significance. [Summary of the invention]

[0020] The automatic elevator handrail cleaning machine based on ultrasonic principle of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Ultrasonic elevator handrail automatic cleaning machine, such as Figure 1-3As shown, it includes a circuit board sealed box 1 and a water tank sealed box 2. The circuit board sealed box 1 and the water tank sealed box 2 are connected by guide rails 3 to facilitate disassembly and installation. The circuit board sealed box 1 is equipped with an ultrasonic vibrator 4 and an ultrasonic generator. The water tank sealed box 2 has a cavity. The head of the ultrasonic vibrator 4 passes through the circuit board sealed box 1 and enters the cavity of the water tank sealed box 2. The water tank sealed box 2 also has an elevator handrail entrance 8 and exit 9.

[0022] The circuit board sealed box 1 has a through-hole on the surface connecting it to the water tank sealed box 2. The head of the ultrasonic transducer 4 passes through this through-hole and enters the cavity of the water tank sealed box 2. A power switch button 5 is provided on the circuit board sealed box 1 to facilitate activating the cleaning machine. The water tank sealed box 2 has a water inlet 6 on its upper surface and a water outlet 7 on its lower surface. Each water inlet 6 and outlet 7 is equipped with a water cap. The water inlet 6 is used to add clean water or other cleaning agents, while the water outlet 7 is used to discharge clean water or other cleaning agents.

[0023] The water tank sealed box 2 has a handrail outlet 9 on its top surface and a handrail inlet 8 on its bottom surface, facilitating handrail movement and ensuring more comprehensive cleaning. A glass clamping notch 10 is provided on the side of the water tank sealed box 2 for clamping the glass. When installing the cleaning machine, the handrail is inserted through the glass clamping notch 10 into the handrail inlet and outlet positions, and the glass clamping notch 10 clamps the elevator glass next to the handrail. The contact area between the glass clamping notch 10 and the elevator glass is sealed, preventing the cleaning machine from shifting and preventing water or cleaning agent from leaking from the water tank sealed box.

[0024] A power cord socket 11 is provided at the bottom of the side of the circuit board sealing box 1 for connecting to an external power source.

[0025] The ultrasonic vibrator 4 and the ultrasonic generator are connected via a circuit and installed in the circuit board sealing box 1 to facilitate dustproof and waterproofing.

[0026] The ultrasonic generator and ultrasonic vibrator 4 in the circuit board sealing box 1 are designed and selected according to the working frequency required for ultrasonic cleaning.

[0027] Principle of the present invention: The present invention is installed in Figure 4The handrail of the supermarket escalator shown in the figure has a glass clamping notch 10 that precisely matches the elevator glass. A water cover is used to seal the water outlet 7 at the bottom of the water tank sealing box 2. Clean water or detergent is added through the water inlet 6 at the top of the water tank sealing box 2. After adding clean water or detergent, another water cover is used to seal the water inlet 6. The power cord socket 11 is plugged into the power supply, and the power switch button 5 is turned on. The ultrasonic generator operates, converting electrical energy into a high-frequency AC signal that matches the ultrasonic vibrator 4. The ultrasonic vibrator 4 operates, converting the high-frequency electrical energy into mechanical vibration, wherein the mechanical vibration process is completed in the clean water or detergent in the water tank sealing box 2. The ultrasonic wave radiates in the water, and the pressure difference therein causes the liquid to flow, generating tens of thousands of tiny bubbles. When the bubbles close, a strong shock wave is generated, which continuously impacts the surface of the object, rapidly peeling off the dirt on the surface and in the gaps of the object, thereby playing the role of cleaning the surface of the object. Using this cleaning machine to clean the supermarket escalator handrail is more effective than traditional manual cleaning and has a high cleaning efficiency.

[0028] The above is only a preferred embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. In other words, simple equivalent changes and modifications made according to the scope of the patent application and the content of the invention description are still within the scope of the patent of the present invention.
