Micro-nano bubble generating device and cleaning machine applying same

Abstract

The invention relates to a micro-nano bubble generating device. The device comprises a hollow shell, a partition plate capable of dividing the internal space of the shell into a first area and a second area is arranged in the shell, the longitudinal section of the partition plate is in a U shape, the space in the U-shaped partition plate is the first area, the space outside the U-shaped partitionplate is the second area, the top of the first area is communicated with the top of the second area, a first water passing hole allowing water in the first area to slowly flow into the second area isformed in the bottom of the partition plate, a water inlet capable of inputting water flow into the first area is formed in the shell, a hole allowing water in the second area to be output is formed in the bottom wall of the second area, and the hole is shaped into a conical hole with a small upper end and a large lower end. In the process of generating micro-nano sparkling water, power does not need to be provided, electric control operation does not need to be conducted, and therefore, the equipment structure is simplified, cost is reduced, and use reliability is improved; the cavitation effect generated by micro-nano bubbles in water and the negative charges on the surface are beneficial to improving a cleaning effect.

Description

technical field [0001] The invention relates to a micro-nano bubble generating device used for washing electrical appliances, and also relates to a cleaning machine using the micro-nano bubble generating device and used for cleaning tableware, vegetables or fruits. Background technique [0002] With the gradual maturity of micro-nano bubble cleaning technology, the application in the field of household appliances has become more extensive. [0003] In the field of industrial applications, nano-scale bubbles refer to tiny bubbles below 1000nm in liquids. Further, bubbles between 1 and 100 μm are called tiny bubbles, and bubbles above 100 μm are called ordinary bubbles. In water, compared with ordinary bubbles, micro-nano bubbles have the characteristics of long existence time, high surface energy, negative charge on the surface, high gas-liquid mass transfer rate, and the ability to spontaneously generate free radicals. Therefore, micro-nano bubbles have the characteristics o...

Problems solved by technology

Most of the above-mentioned existing micro-nano bubble generating devices use an air pump to provide a power source to mix in air, and after the air and water are fully mixed and dissolved, the pressure is released to obtain micro-nano bubbles with a high concentration. The realization structure of this method is relatively complicated and costly. High, and need to rely on the circuit for control, poor reliability
