Method and device for generating microbubble water

Abstract

The invention relates to a microbubble water generation method and a generation device. The microbubble water generation method comprises the following steps: by pressing down a start key, a to-be-filled gas is imported into a dissolved gas tank from a to-be-filled gas conveying source, and gas is stopped conveying when the input to-be-filled gas reaches the needed amount; then a compression pump starts working, then water is conveyed into the dissolved gas tank until a pressure switch actuates, a controller controls an effluent water electromagnetic valve to switch on, to obtain the prepared microbubble water, then the compression pump continues working and stops working until the needed ratio of the import amount of water to the amount of the imported to-be-filled gas is achieved; and the controller controls a drain mechanism to work, and the microbubble generation device is under standby state until the remaining microbubble water in the dissolved gas tank is drained out. The invention further discloses a microbubble generation device corresponding to the method. By adopting the method and the device, a gas inlet channel is not easily plugged, the defects in the prior art can be avoided, so that the device can reliably work for long time, and the device also has a water-saving function.

Description

technical field [0001] The invention relates to the technical field of producing microbubble water by mixing air and water in a certain proportion, and specifically refers to a method and device for producing microbubble water mainly used for bathing. Background technique [0002] Microbubble is a general term for bubbles with a diameter of less than 50 μm. When a large number of microbubbles form milk-like water, it is called microbubble water. Existing micro-bubble water generating devices generally include a compression pump (i.e. a high-pressure water pump), a water inlet pipe connected to the inlet of the compression pump, an air dissolving tank connected to the outlet of the compression pump, and an outlet pipe connected to the outlet of the dissolving air pipe. The water pipe, such as the structure disclosed in the Chinese patent application publication number CN102728251AY "Inlet and Outlet Water Module of Microbubble Generator". When the microbubble generator is wo...

Problems solved by technology

[0005] However, it was found during use that because the above-mentioned microbubble water is generated online, that is, water and air (or other gases) are simultaneously input into the dissolved gas tank through a compression pump, the precondition for generating microbubbles is air (or other gases) ) and water should be input in a certain ratio. If air (or other gases) is excessively mixed into the water, the microbubble water flowing out from the shower will form a short-term shock wave due to too many large bubbles, which will cause unstable microbubble water.

If the amount of air (or other gases) mixed into the water is insufficient, the number of microbubbles formed will be small, which will not achieve better cleaning and massaging effects on the human body.

And the proportion of air (or other gases) relative to water is very small, so in this device for generating microbubble water online, the aperture of the gas delivery channel will be made very small to ensure the delivery flow, but this A channel with a small aperture, which is prone to clogging after a long time of use, resulting in the failure of the microbubble water dispenser to work normally

Moreover, in this online production method, the microbubble water that just comes out of the water outlet of the dissolved air tank often needs to be discharged for a period of time before it can be used because the initial pressure in the dissolved gas tank is still low and the content of microbubbles is small. There is also a waste of water resources
