To sum up, the present invention is to install the first net 10 and the second net 20 in the body 40 of the shower head or the faucet, and to make the first connection surface 11 of the first net 10 and the second connection surface 22 of the second net 20 oppositely disposed, at this time, the first through hole 12 and the second through hole 21 will form the diversion channel T for the liquid L to pass through, when the liquid L flows in from the liquid inlet 41 of the water inlet unit 42 of the body 40, the liquid L will generate negative pressure at the connection position of the first connection surface 11 and the second connection surface 22 through the diversion channel T, so that the external air is sucked from the air inlet through hole 13 of the first net 10 and mixed with the liquid L at the connection position, the user can directly spray on the body, wherein, the first air inlet groove 15 will be formed between the air inlet through hole 13 and the first through hole 12, therefore, after the first mesh body 10 and the second mesh body 20 are assembled, the distance between the first mesh body 10 and the second mesh body 20 does not need to be adjusted, so as to ensure the quality of the microbubble generation module 100.
The present invention has been described in detail, but the above embodiments are only examples of the present invention, and the scope of the present invention should not be limited thereby, and all equivalent changes and modifications made in the claims of the present invention should be covered by the present invention.
