Micro-bubble generator
A micro-bubble generator is provided between an input end and an output end of a water outlet device. The micro-bubble generator includes a water inlet member and a water outlet member. A gas inlet gap is remained between the water inlet member and the water outlet member, with the gas inlet gap being communicated to external air, such that the external air is allowed to enter the micro-bubble generator for gas-liquid mixing and generate minute and dense bubbles.
1. A micro-bubble generator provided between an input end and an output end of a water outlet device, said micro-bubble generator comprising:
a water inlet member, including a first main body adjacent to said input end, and a first channel penetrating said first main body, said first main body being provided at one end penetrated by said first channel with a first junction surface; and
a water outlet member, including a second main body adjacent to said output end, and a second channel penetrating said second main body, said second main body being provided at one end penetrated by said second channel with a second junction surface,
wherein said water inlet member and said water outlet member are abutted against each other, with said first junction surface facing said second junction surface, said first channel being communicated with said second channel, and one of said first junction surface and said second junction surface is provided with a plurality of chiseled shallow recesses which forms a gas inlet gap after said first junction surface is engaged with said second junction surface, said gas inlet gap communicates external air to said first channel and said second channel.
2. The micro-bubble generator according to claim 1 , wherein said water inlet member includes a plurality of first branching channels arranged alongside of said first channel, wherein said water outlet member includes a plurality of second branching channels arranged alongside of said second channel, and an engagement between one of said plurality of first branching channels and one of said plurality of second branching channels is communicated with said gas inlet gap.
3. The micro-bubble generator according to claim 2 , wherein said water inlet member, on one side adjacent to said input end, includes a raised platform penetrated by said first channel, and a notch depressed around said raised platform and penetrated by each of said plurality of first branching channels.
4. The micro-bubble generator according to claim 2 , wherein each of said plurality of first branching channels and/or each of said plurality of second branching channels may be inclined with respect to said first channel and said second channel, respectively.
5. The micro-bubble generator according to claim 1 , further comprising a sleeve and an air vent perforation penetrating said sleeve, said water inlet member and said water outlet member being put into said sleeve and fixed, while said gas inlet gap being communicated with said air vent perforation.
6. The micro-bubble generator according to claim 5 , further comprising an eddy current guiding pipe located at one end, adjacent to said second main body, of said sleeve, said eddy current guiding pipe including a plurality of blades in a spiral manner, a plurality of eddy current passages, wherein each of said plurality of eddy current passages is arranged between two of said plurality of blades, and an outer casing tube surrounding said plurality of blades and said plurality of eddy current passages, a plurality of stepped surfaces being provided on a surface of each of said plurality of blades corresponding to each of said plurality of eddy current passages.
