Cavitation part of micro-bubble generator, micro-bubble generator and clothes processing device

Abstract

The invention discloses a cavitation part of a micro-bubble generator, the micro-bubble generator and a clothes processing device. The cavitation part is provided with a cavitation inlet and a cavitation outlet, wherein water flow enters and exits from the cavitation inlet and the cavitation outlet. A plurality of Venturi channels extending from the cavitation inlet to the cavitation outlet are defined in the cavitation part. Each Venturi channel sequentially comprises a gradually-shrinking section, a throat pipe and a gradually-expanding section in the water flow flowing direction, wherein the flow area of the gradually-shrinking section is gradually reduced in the direction from the cavitation inlet to the throat pipe, and the flow area of the gradually-expanding section is gradually increased in the direction from the throat pipe to the cavitation outlet. According to the cavitation part, on one hand, the bubble making capacity of the cavitation part can be ensured; and on the otherhand, the structure is simple, machining is convenient, and the cost is easy to control.

AI Technical Summary

Problems solved by technology

At present, most of the microbubble generators used in the above fields have complex structures, some require additional water pumps, and some require multiple valves to control. At the same time, there are many restrictions on the way of entering the water, resulting in high costs.

Among them, the setting of the cavitation part of the micro-bubble generator not only occupies a large volume, but also has an unreasonable structure, and it is very inconvenient to install and manufacture.
