The micro-nano bubble generating device is a device capable of generating micro-nano bubbles, is also called as a micro-nano bubble generating device and is generally arranged in a water path system, when tap water enters the water path system from a water inlet, the filtered tap water is mixed with air to form water-gas mixed liquid, and then micro-nano bubbles are generated in the micro-nano bubble generating device to form bubble water. The existing micro-nano bubble generating device generally leads water-gas mixed liquor to flow through a conical channel and flow from a large opening to a small opening of the conical channel from bottom to top so as to limit the flow of the water-gas mixed liquor, accumulate pressure in the process, and lead the water-gas mixed liquor to be released instantaneously when passing through the small opening, thereby generating micro-nano bubbles in the process. However, the existing micro-nano bubble generating device has a short tapered channel, insufficient pressure accumulation to water flow and insufficient pressure release, and has low efficiency of generating micro-nano bubbles and poor bubbling effect.

Based on the technical scheme, the utility model provides the micro-nano bubble generating device, the water path system and the household appliance, and aims to solve the technical problems that the micro-nano bubble generating device in some technologies has low efficiency of generating micro-nano bubbles and has poor bubbling effect.

The utility model provides a micro-nano bubble generating device, which comprises a main body 100 and a foaming piece 200, as shown in figures 1 and 2; the main body 100 is provided with a water inlet 300 and a water outlet 400, and the water inlet 300 and the water outlet 400 are respectively arranged at two opposite ends of the main body 100; the foaming member 200 is disposed in the main body 100, and a spiral passage surrounding the foaming member 200 is provided on the foaming member 200, the spiral passage forming a spiral water path, and the spiral passage spirally extends in a direction from the water inlet 300 to the water outlet 400.

In the process, compared with the existing conical channel, the spiral channel prolongs the length of the channel, prolongs the flowing time of water flow in the channel, and increases the dissolved air quantity along the spiral flow of the water flow, so that more micro-nano bubbles can be generated. The utility model solves the technical problems of low efficiency and poor bubbling effect of the micro-nano bubble generation device for generating micro-nano bubbles.

The micro-nano bubble generating device realizes pressure release of water flow through the foaming piece 200 and generates a large amount of micro-nano bubbles in the pressure release process. Specifically, after water flows into the micro-nano bubble generating device from the water inlet 300, the water flows in from a port of the spiral channel in the foaming piece 200, which is close to the water inlet 300, flows through the whole spiral channel, flows out from a port close to the water outlet 400, the pressure of the water flow is released when the water flows out, and a large amount of micro-nano bubbles can be generated by the water flow in the pressure release process, so that the purpose of preparing the micro-nano bubbles by the micro-nano bubble generating device is achieved.
